- Albert in U.S. Pat. No. 4,186,842 (1980) shows a normally closed lid in which access slits are formed by downward force.
- lids all have one or more disadvantages, including complexity, unreliability, costliness, difficulty of use, awkwardness, high cost, etc.
- a lid with a closure member that (9) covers the drink opening completely until it is opened by the user, (10) once opened remains in a stable open position until closed by the user, (11) can be re-closed by the user, (12) is made from a single piece of material, (13) can be opened and closed with a one-hand operation, (14) is sanitary, (15) is integrated into a standard style of lid with a raised drink through spout configuration, (16) the user can more easily use for drinking through the lid, and (17) is more resistant to splashing when the drink hole is open.
- a new and improved lid has a raised drink-through spout with a valved drink opening.
- the lid is formed from one piece of material.
- the lid has a mounting portion at its base which includes a resilient annular gripping groove configured to grip the bead on the top of the cup.
- An annular outer sidewall or turret preferably frusto-conical in shape, extends upward and inward from the mounting portion and has an annular top surface or rim having a generally circular periphery at the top of the outer sidewall.
- the turret has a central recess portion which forms a center panel of the lid. The rim is higher and wider at one side, thereby forming a raised drinking spout.
- the drink-through valve in the drinking spout comprises a rectangular flap in the top surface or ridge of the rim.
- the flap has an integrally formed upward protrusion or post.
- the flap is defined by a cut line along the front edge, a curved cut line on each side edge, and a hinge along the back edge.
- the hinge line preferably is a “living” or integral hinge at the inner edge of the top wall.
- the user opens the valve applying downward force to the top of the post, forcing the flap to bend downwardly along the hinge line so that the flap extends downwardly at an angle from the ridge or surface of the rim.
- the hinge of the flap has a spring action that urges the flap to return to its closed and horizontal orientation.
- the top edge of the post is pushed past the cut front or catch edge of the top wall, it will catch under this edge and lock the flap in an open position. This will preventing the flap from returning and hold the flap—and hence the valve—in an open position to create a drink-through opening.
- the user can then simply drink from the lid as normal by placing their lips around the raised drink spout.
- the user applies inward force to a point on the outer sidewall below the cut front edge.
- inward force to a point on the outer sidewall below the cut front edge.
- it causes the front wall to deflect inwardly and the cut front edge of the drink hole to distort outwardly, widening the hole.

- This lid has an annular, bottom rim 10 which has a slight flange 10 F extending out from its bottom.
- the underside of rim 10 forms a downwardly facing annular cup-rim-gripping and sealing groove 12 (best seen in FIG. 2C ).
- a turret or domed portion 14 extends up from inside of groove 12 ; turret 14 has a truncated conical shape and has an annular vertical wall 16 .
- Turret 14 has an annular top horizontal surface, or ridge 18 that extends in from the top of wall 16 , and a recess 20 that is surrounded and below ridge 18 .
- wall 16 , ridge 18 , and recess 20 form an annular upper rim 22 .
- rim 22 is the top portion of turret 14 and encircles and defines recess 20 .
- the front half of rim 22 slopes upwardly and then levels off to form a raised or higher and wider drinking portion or spout 24 at the front.
- Spout 24 has a drink opening 26 which is cut out of ridge 18 .
- a small air-relief hole 26 A is also cut in ridge 18 , opposite opening 26 .
- opening 26 is always patent or op en. This is problematic to people that want to purchase a beverage and then take it somewhere else, such as their office, to be consumed. A beverage inside the cup below (not shown) can splash out from the lid while the cup is being carried. Additionally, heat readily escapes from the open hole before the user is ready to consume their drink. As a result, some beverage shop owners have resorted to placing a piece of tape over the hole for the customer so that beverage and heat do not escape until the user is ready to enjoy their drink. This solution is time consuming, messy, and not sanitary.
- valved lids are known that prevent splashing and reduce heat loss, but these have many disadvantages, including interference with the user's drinking, dripping of the beverage within when the valve is opened, use of a relatively large amount of material, excess time and labor to use, high expense to make, a large amount of material to fabricate, complexity, unreliability, difficulty and awkwardness to use, and an inability to stay in an open configuration until closed by a user.
- FIG. 2A Lid with Valve-Overall Description
- FIG. 2A shows a lid with a valve according to the invention.
- the lid is similar to that of FIG. 1 , and bears all of the same reference numerals except that in lieu of a patent or open drinking hole 26 , it has a valve 28 .
- Valve 28 comprises a generally rectangular hinged flap 28 F that has an integral upstanding post or protrusion 28 P. Flap 28 F has curved sides and a straight front edge and a back edge that is hinged to top surface 18 by a living or natural hinge 28 H. I.e., hinge 28 H is at the inner, hinge edge of the hole (now designated 26 ′). The hinge is formed along the inner or back edge of the annular top surface adjacent the recess.
- a section of the hinging edge can be made straight.
- the hinge can be designed as part of the top surface by forming a groove where flap 28 F is intended to bend. When flap 28 F is coplanar with ridge or top surface 18 as shown, the valve is closed, but it can easily be opened by depressing flap 28 F, as will be described, to provide a drinking opening.
- the lid of FIG. 2A preferably is made by thermoforming, but can also be made by any of a variety of manufacturing processes, such as injection molding, and/or vacuum forming. Preferably it is made from a plastic such as polystyrene (preferred), polypropylene, polyethylene, or any other suitable plastic material.
- Post 28 P preferably is an integral part of flap 28 F and is made by thermoforming so that the material of the post is stretched out of the body of the flap.
- the lid was sized to mate with a paper cup (not shown) having a 90 mm diameter rim that was 3 mm wide. Flap 28 F was 14 mm by 4 mm and post 28 P was 4 mm high and 3 mm in diameter. The rest of its dimensions were sized proportionately.
- valve 28 improves upon prior-art lids since, inter alia, it is easily resealable, does not interfere or hinder with the user's drinking, prevents the beverage in the cup from splashing out, and keeps the beverage warmer.
- FIGS. 2 B and 2 C Top and Side-Sectional Views
- FIGS. 2B and 2C show top and side sectional views of the lid, with FIG. 2C taken as indicated by section lines 2 C- 2 C in FIG. 2B .
- recess 20 is in the center of the lid and is surrounded by rim 22 with its ridge 18 .
- Spout 24 includes valve 28 with flap 28 F and its post 28 P.
- flap 28 F has an elongated rectangular shape with curved side edges, similar to the shape of hole 26 of FIG. 1 or hole 26 ′ of FIG. 2B .
- FIG. 2C shows bottom rim 10 and groove 12 in section; groove 12 is forced over the top rim of a paper cup (not shown) so that the groove will hold the lid tightly to the cup.
- Wall 16 extends up inside rim 10 to form turret or domed portion 14 .
- Ridge 18 of turret 14 has raised portion or spout 24 and the top portion of the turret forms upper rim 22 that forms and encircles recess 20 . Note that the portion of upper rim 22 comprising spout 24 is slightly wider than the rest of upper rim 22 .
- FIGS. 3A, 3B , and 3 C Perspective, Top-Enlarged, and Part-Side-Sectional Views of Lid with Open Valve
- FIG. 3A shows a perspective view of the lid with valve 28 pushed down and open to form drinking aperture or hole 26 ′.
- Hole 26 ′ is similar to hole 26 of FIG. 1 , except that flap 28 F extends down from the inner edge of the hole.
- Post 28 P is also pushed down below the adjacent portion of ridge 18 .
- FIG. 3B shows an enlarged plan view of the lid of FIG. 3A .
- flap 28 F is bent down at living hinge 28 H, creating a patent or open hole 26 ′. I.e., one side of the flap is attached to the back or hinge side of hole 26 ′ at living hinge 28 H.
- the tip of post 28 P is locked under the opposite, front, or catch edge of hole 26 ′. If the tip of the post were not locked under the catch edge of the hole, hinge 28 H would tend to cause the flap to return to its closed, horizontal position. However since the post is locked under the catch edge, the flap is bistable, i.e., it has two stable positions: open and closed.
- the post is sized so that when the flap is rotated so that it extends down at an acute angle to top surface 18 of the spout, and the post is subtended by top surface 18 and flap 28 F, the tip of the post will contact the catch edge of hole 26 ′, so that the flap will remain in the open position.
- FIG. 3C shows a side, sectional, detailed view of the portion of the lid containing valve 28 as taken along line 3 C- 3 C of FIG. 3B .
- flap 28 F is bent down at living hinge 28 H, creating hole 26 ′.
- the tip of post 28 P is locked under the front or catch edge of hole 26 ′.
- FIG. 4 Part-Side-Sectional Views of Lid with Closing Valve
- FIG. 4 is a side sectional view of the lid of FIG. 3A showing the valve returning to its closed position.
- a user pushes in on wall 16 with a finger 30 as indicated, the portion of the wall contacted by finger 30 is deformed or pushed in as indicated. This causes the top portion of the wall above the finger and the adjacent part of ridge 18 including the catch edge of hole 26 ′ to be deformed outwardly as indicated. This will allow the tip of post 28 P to slip up past the catch edge as also indicated.
- Flap 28 F is shown in the process of rotating back to its horizontal or closed position. Living hinge 28 H will cause the flap to rotate or spring back until it is substantially closed and coplanar with ridge 18 , as shown in FIGS. 2A to 2 C.
- Valve Closed The inventive lids are supplied with their valves 28 in the closed state ( FIG. 2A ).
- Valve flap 28 F is coplanar with its seat, which is part of upper rim 22 .
- the flap will normally have this position, or bent or rotated slightly upwardly to a position just above its seat (not shown) after it is cut in the punching die. If after punching it is rotated to a position just above the seat, it can be pushed down in the die so that it is coplanar with its seat as shown in FIG. 2A ; this will enable the user to push down the flap to open the valve more easily. (It can also be pushed lower, as discussed infra in connection with FIG. 5 .)
- a cup (not shown) is filled with a beverage, either at a beverage store, a home, a vendor, etc. and the lid is snapped down over the rim of the cup.
- the user or drinker carries the lidded cup away, e.g., to a place of employment, a vehicle, a work site, etc. Since the valve is closed, the lid is substantially entirely closed so that the beverage within will not splash out, despite rough handling. Also, the escape of heat (or the entrance of heat if the beverage is chilled) will be reduced.
- valve provides splash resistance even when the drink hole is open.
- hinged flap 28 F and post 28 P act as a splash guard on the inside of the lid to block some liquid from splashing through opening 26 ′.
- Valve Closing if the user wishes to interrupt their drinking before consuming all of the beverage in the cup, they can close valve 28 as follows: As shown in FIG. 4 , the user uses a finger 30 to push inwardly on wall 16 , below ridge 18 . This causes this portion of wall 16 to deflect inwardly as shown, which in turn causes the upper part of wall 16 and front and catch edge of hole 26 ′ to distort outwardly far enough to allow the tip of post 28 P to slip upwardly, past the front edge of hole 26 ′ so that flap 28 F closes and re-seals opening 26 ′. Thus the cup can now be carried and handled without its beverage splashing out and reducing the transmission of heat though hole 26 ′. The user removes their finger 30 from wall 16 , allowing the wall to return to its normal, undistorted conformation and allowing hole 26 ′ to return to its normal conformation.
- Drink spout 24 can be squeezed or rolled between a finger and thumb. This will distort this portion of the lid and thereby release the post from the catch edge and allow the flap to close.
- the user can remove the lid from the cup and push the underside of the flap up with a finger to close the flap. The user can then reattach the lid to the cup.
- FIG. 5 Value Flap Pushed Below Seat
- the lids may be formed with valve flap 28 F coplanar with its seat as shown in FIG. 2A , or just above its seat (not shown).
- FIG. 3C This position can be created at the time the lid is formed in the punching die (not shown) by providing the female die with a spring-loaded stripper pin (not shown, but well-known to those skilled in the art) to push the flap slightly downward, below its seat after it is punched.
- the flap will self-rotate upwardly to this position after it is pushed down lower and released since its hinge 28 H will rotate it upwardly until its edge contacts the edge of its seat, which will stop it.
- a drinking cup lid with a drinking orifice that (1) improves upon prior-art lids, (2) does not require the use of tape to close the drink hole, (3) is easily resealable, (4) does not interfere or hinder with the user's drinking, (5) does not have any part that drips when opened, (6) uses a relatively small amount of material, (7) requires little time, materials, and labor to use, (8) is simple, reliable, economical, and facile to use, (9) covers the drink opening completely until it is opened by the user, (10) once opened will remain in a stable open position until closed by the user, (11) can be re-closed by the user, (12) is made from a single piece of material, (13) can be opened and closed with a one-hand operation, (14) is sanitary, (15) is integrated into a standard style of lid with a raised drink through spout configuration, (16) the user can more easily use for drinking through the lid, and (17) is more resistant to splashing when the
- the material, size, and plastic forming method can be changed.
- the valve need not be on the top surface of the spout, but instead can be on a side surface.
- the post can be glued on, rather than being stamped from the flap.
- a nubbin, mound, or other protrusion can be used.
- the shape of the flap can be changed to oval, circular, triangular, rectangular, etc.
- the flap can be hinged to the outer edge of the hole, or a side edge, rather than the inner edge.
- the flap can be larger than the drink-through opening so that when closed it will lie adjacent, either slightly above or below the top surface of the spout, but not coplanar with the top surface.
- the arrangement for attaching the lid to the cup can be changed to, e.g., screw-on, glue-on, etc.
- a recess in the lid need not be provided; instead the top of the lid can be flat with an upstanding valved spout.
- the lid can have shapes other than circular, such as oval, rectangular, triangular, polygonal, etc.
- the lid can be used for cold beverages and for containers for substances other than beverages, i.e., containers for non-potable liquid and particulate products.
- Embossed lettering such as the word(s) “push” or “push down” can be embossed or debossed into the surface of the raised drink spout on either side of the valve to instruct the user on how to open the lid.
- embossed lettering such as the word(s) “push”, “push here” or “push here to close” can be embossed or debossed into the front surface of the lid along wall 16 just below the value to educate the users on how to reclose the lid.
- an embossed button, semi sphere, or bump can be formed at this location on wall 16 to facilitate closing of the flap more easily.
Abstract
Description
- This patent issued from an application that is a continuation of application Ser. No. 10/944,387, filed 2004 Sep. 17, now abandoned.
- 1. Field of Invention
- This invention relates generally to drinking containers, specifically to valved lids for such containers.
- 2. Prior Art
- Fast food restaurants, beverage shops, and other food-service establishments serve hot beverages in disposable cups with lids or covers. The lids keep the cup's contents hot and prevent the liquid from spilling. Many lids have openings so the user can drink the beverage from the cup below without removing the lid. Some lids have raised drink-through spouts that allow the user to place both lips around the spout to more easily and safely sip the beverage.
- For example U.S. Pat. No. 4,589,569 to Clements (1986) discloses a dome lid with a raised and wide drink-through spout. An open drink hole is cut out of the top of the spout.
- Pat. Des 417,845 to Sadlier (the present inventor) et al. (1999) also discloses a dome lid with a wide raised drink-through spout having an open drink hole in the top of the spout.
- Both of the above lids have been commercially accepted in the market—many millions are sold each week. Despite their success, one disadvantage is that the drink hole is always open. This is problematic to people that want to purchase a beverage and then take it somewhere else, such as their office, to be consumed. The beverage can splash out from the open drink hole while the cup is carried. Additionally, heat readily escapes from the open drink hole before the user is ready to consume their drink. As a result, some beverage shop owners have resorted to placing a piece of tape over the hole so that beverage and heat do not escape until the user is ready to enjoy their drink. This solution is time consuming, messy, and unsanitary.
- In order to address this problem inventors have come up with solutions such as disclosed in U.S. Pat. No. 4,899,902 to DeMars (1990) and U.S. Pat. No. 6,644,490 to Clarke (2003). These patents disclose lids with raised drink-through spouts having open drink holes. The lids further include a flexible arm portion connected to the lid with a closure plug at the end of the arm. When a user or vendor wants to close the drink opening, they insert the plug-end of the arm into the open drink hole. When they want to open the lid again, they remove the plug from the drink hole. While an improvement over non-closable raised drink spout lids, these lids have not gained widespread use because the attached flexible arm is awkward and can interfere with the user when they attempt to drink from the cup. After the plug is removed from the drink hole it is often wet with the beverage, which tends to drip from the plug onto the user's clothing. Also, this type of lid uses more material and lid more difficult to make than a standard raised drink-through spout lid. The operation of opening and closing the hole is cumbersome and requires two hands. The lids are produced and boxed with the hole initially open; therefore the server must manually insert the plug into the lid at the time the beverage is served to the consumer. This takes more labor time at the service counter. Because of these deficiencies, these types of lid have not gained widespread commercial acceptance or use.
- U.S. Pat. No. 6,732,875 to Smith et al. (2004) and published patent application 2002/0,011,494 to Lukacevic show other two-piece reclosable lids with raised drink-through spouts. These lids have two parts: an external cover having the raised drink through spout with an open drink hole, and an internal rotatable disk having a drink-hole-closing member. The movable disk also has a post that extends up through a slot in the external cover. By moving the post from one side of the slot to the other, the disk can be rotated to open and close the drink hole. While a functional improvement over the lids mentioned above, the two-piece construction is expensive to make. Additional plastic material is required to form both the external cover and the internal movable disk, and additional machinery processing is required to fasten the two parts together. Thus these lids have a significant cost disadvantage over the other prior-art lids discussed above.
- Herbst, in U.S. Pat. No. 4,925,051 (1990), and Albert, in U.S. Pat. No. 4,186,842 (1980), shows a normally closed lid in which access slits are formed by downward force.
- Zoellick, in U.S. Pat. No. 4,081,103 (1978), Schaefer, in U.S. Pat. No. 5,799,814 (1998), and Warden et al., in U.S. Pat. No. 5,398,843 (1995), show a lids with a normally closed flap that can be depressed for drinking.
- Schutz, in U.S. Pat. No. 3,860,162 (1975), shows a lid with a slit that is sealed by a normally closed valve that can be opened by a user's upper lip.
- Yamazaki, in U.S. Pat. No. 4,113,135 (1978), Galloway et al., in U.S. Pat. No. 4,345,695 (1982), Boller, in U.S. Pat. No. 5,911,331 (1999), and Amberg et al., in U.S. Pat. No. 4,184,604 (1980), show lids with drinking-hole-sealing flaps that can also be opened by a user's lip.
- Montemerano, in U.S. Pat. No. 4,333,583 (1982), and Ryan et al., in published patent application 2004/0,094,549, show lids with a spout that has a cover that can be opened for drinking.
- Coy, in U.S. Pat. No. 4,782,975 (1988), shows a lid with a spout with a valve in the spout. The valve can be opened by lip pressure.
- Kick, in U.S. Pat. No. 5,894,950 (1999), and Van Melle, in U.S. Pat. No. 6,089,397 (2000), show lids with a flap with a frangible attachment so that it can be broken away from the rest of the lid to open it to allow drinking.
- Bruce et al., in U.S. Pat. No. 6,419,105 (2002), shows a lid with a partial spout or funnel (of a non-drink through variety) and a cylindrical portion below the spout that can be deformed to open or close it in a bistable manner. The operation of this lid does not allow for a drink-through type drink spout popular with consumers and food-service operators alike.
- Hundley et al., in U.S. Pat. No. 6,612,456 (2003), and Schmidtner et al., in published patent application 2003/0,218,017, show lids with a drinking hole and a hinged valve comprising a hollow raised tab that can be depressed to open the hole.
- These lids all have one or more disadvantages, including complexity, unreliability, costliness, difficulty of use, awkwardness, high cost, etc.
- Thus, all present lids with raised drink-through spouts have various disadvantages: the beverage can to splash out and lose heat, tape is awkward to use and is not resealable, sealing plugs interfere with the user's drinking, drip the beverage within when opened, use a relatively large amount of material, and require excess time and labor to use, two-part lids are expensive to make and require excess material, and other lids are complex, unreliable, expensive, difficult to use, and awkward.
- Therefore several advantages of the present invention are to provide a drinking cup lid with a drinking orifice that (1) improves upon prior-art lids, (2) does not require the use of tape to close the drink hole, (3) is resealable, (4) does not interfere or hinder with the user's drinking, (5) does not have any part that drips when opened, (6) uses a relatively small amount of material, (7) requires little time, materials, and labor to use, (8) is simple, reliable, economical, and facile to use.
- Other advantages are to provide a lid with a closure member that (9) covers the drink opening completely until it is opened by the user, (10) once opened remains in a stable open position until closed by the user, (11) can be re-closed by the user, (12) is made from a single piece of material, (13) can be opened and closed with a one-hand operation, (14) is sanitary, (15) is integrated into a standard style of lid with a raised drink through spout configuration, (16) the user can more easily use for drinking through the lid, and (17) is more resistant to splashing when the drink hole is open.
- Further advantages will become apparent from a consideration of the drawings and ensuing description.
- According to the invention, a new and improved lid has a raised drink-through spout with a valved drink opening. The lid is formed from one piece of material. The lid has a mounting portion at its base which includes a resilient annular gripping groove configured to grip the bead on the top of the cup. An annular outer sidewall or turret, preferably frusto-conical in shape, extends upward and inward from the mounting portion and has an annular top surface or rim having a generally circular periphery at the top of the outer sidewall. The turret has a central recess portion which forms a center panel of the lid. The rim is higher and wider at one side, thereby forming a raised drinking spout.
- The drink-through valve in the drinking spout comprises a rectangular flap in the top surface or ridge of the rim. The flap has an integrally formed upward protrusion or post. The flap is defined by a cut line along the front edge, a curved cut line on each side edge, and a hinge along the back edge. The hinge line preferably is a “living” or integral hinge at the inner edge of the top wall.
- The user opens the valve applying downward force to the top of the post, forcing the flap to bend downwardly along the hinge line so that the flap extends downwardly at an angle from the ridge or surface of the rim. The hinge of the flap has a spring action that urges the flap to return to its closed and horizontal orientation. However, when the top edge of the post is pushed past the cut front or catch edge of the top wall, it will catch under this edge and lock the flap in an open position. This will preventing the flap from returning and hold the flap—and hence the valve—in an open position to create a drink-through opening. The user can then simply drink from the lid as normal by placing their lips around the raised drink spout.
- To re-close the valve, the user applies inward force to a point on the outer sidewall below the cut front edge. When such force is applied at this release point, it causes the front wall to deflect inwardly and the cut front edge of the drink hole to distort outwardly, widening the hole. This releases the top edge of the post, allowing it to move upwardly so that the flap can spring back to its horizontal and closed position.

FIG. 1 shows a perspective view of a prior-art drink-through domed cup lid similar to the lid shown in the Sadlier et al. design patent, supra. This lid has an annular, bottom rim 10 which has aslight flange 10F extending out from its bottom. The underside ofrim 10 forms a downwardly facing annular cup-rim-gripping and sealing groove 12 (best seen inFIG. 2C ). A turret ordomed portion 14 extends up from inside ofgroove 12;turret 14 has a truncated conical shape and has an annularvertical wall 16.Turret 14 has an annular top horizontal surface, orridge 18 that extends in from the top ofwall 16, and arecess 20 that is surrounded and belowridge 18. Thuswall 16,ridge 18, andrecess 20 form an annularupper rim 22. Stated differently, rim 22 is the top portion ofturret 14 and encircles and definesrecess 20. The front half ofrim 22 slopes upwardly and then levels off to form a raised or higher and wider drinking portion or spout 24 at the front.Spout 24 has adrink opening 26 which is cut out ofridge 18. A small air-relief hole 26A is also cut inridge 18,opposite opening 26. - As stated, the lid of
FIG. 1 has been commercially accepted in the market and many millions are sold each week. Despite its success, one disadvantage is that opening 26 is always patent or op en. This is problematic to people that want to purchase a beverage and then take it somewhere else, such as their office, to be consumed. A beverage inside the cup below (not shown) can splash out from the lid while the cup is being carried. Additionally, heat readily escapes from the open hole before the user is ready to consume their drink. As a result, some beverage shop owners have resorted to placing a piece of tape over the hole for the customer so that beverage and heat do not escape until the user is ready to enjoy their drink. This solution is time consuming, messy, and not sanitary. - As also stated, valved lids are known that prevent splashing and reduce heat loss, but these have many disadvantages, including interference with the user's drinking, dripping of the beverage within when the valve is opened, use of a relatively large amount of material, excess time and labor to use, high expense to make, a large amount of material to fabricate, complexity, unreliability, difficulty and awkwardness to use, and an inability to stay in an open configuration until closed by a user.

FIG. 2A —Lid with Valve-Overall Description -
FIG. 2A shows a lid with a valve according to the invention. The lid is similar to that ofFIG. 1 , and bears all of the same reference numerals except that in lieu of a patent oropen drinking hole 26, it has avalve 28.Valve 28 comprises a generally rectangular hingedflap 28F that has an integral upstanding post orprotrusion 28P.Flap 28F has curved sides and a straight front edge and a back edge that is hinged totop surface 18 by a living ornatural hinge 28H. I.e., hinge 28H is at the inner, hinge edge of the hole (now designated 26′). The hinge is formed along the inner or back edge of the annular top surface adjacent the recess. In order to assist in the hinging function, a section of the hinging edge can be made straight. Alternatively the hinge can be designed as part of the top surface by forming a groove whereflap 28F is intended to bend. Whenflap 28F is coplanar with ridge ortop surface 18 as shown, the valve is closed, but it can easily be opened by depressingflap 28F, as will be described, to provide a drinking opening. - The lid of
FIG. 2A preferably is made by thermoforming, but can also be made by any of a variety of manufacturing processes, such as injection molding, and/or vacuum forming. Preferably it is made from a plastic such as polystyrene (preferred), polypropylene, polyethylene, or any other suitable plastic material.Post 28P preferably is an integral part offlap 28F and is made by thermoforming so that the material of the post is stretched out of the body of the flap. In one embodiment, the lid was sized to mate with a paper cup (not shown) having a 90 mm diameter rim that was 3 mm wide.Flap 28F was 14 mm by 4 mm and post 28P was 4 mm high and 3 mm in diameter. The rest of its dimensions were sized proportionately. - As will be shown,
valve 28 improves upon prior-art lids since, inter alia, it is easily resealable, does not interfere or hinder with the user's drinking, prevents the beverage in the cup from splashing out, and keeps the beverage warmer. - FIGS. 2B and 2C—Top and Side-Sectional Views
-
FIGS. 2B and 2C show top and side sectional views of the lid, withFIG. 2C taken as indicated bysection lines 2C-2C inFIG. 2B . As shown inFIG. 2B ,recess 20 is in the center of the lid and is surrounded byrim 22 with itsridge 18.Spout 24 includesvalve 28 withflap 28F and itspost 28P. Note thatflap 28F has an elongated rectangular shape with curved side edges, similar to the shape ofhole 26 ofFIG. 1 orhole 26′ ofFIG. 2B . -
FIG. 2C showsbottom rim 10 andgroove 12 in section;groove 12 is forced over the top rim of a paper cup (not shown) so that the groove will hold the lid tightly to the cup.Wall 16 extends up insiderim 10 to form turret ordomed portion 14.Ridge 18 ofturret 14 has raised portion or spout 24 and the top portion of the turret formsupper rim 22 that forms and encirclesrecess 20. Note that the portion ofupper rim 22 comprisingspout 24 is slightly wider than the rest ofupper rim 22. -
FIGS. 3A, 3B , and 3C—Perspective, Top-Enlarged, and Part-Side-Sectional Views of Lid with Open Valve -
FIG. 3A shows a perspective view of the lid withvalve 28 pushed down and open to form drinking aperture orhole 26′.Hole 26′ is similar tohole 26 ofFIG. 1 , except thatflap 28F extends down from the inner edge of the hole.Post 28P is also pushed down below the adjacent portion ofridge 18. -
FIG. 3B shows an enlarged plan view of the lid ofFIG. 3A . Note thatflap 28F is bent down at livinghinge 28H, creating a patent oropen hole 26′. I.e., one side of the flap is attached to the back or hinge side ofhole 26′ at livinghinge 28H. The tip ofpost 28P is locked under the opposite, front, or catch edge ofhole 26′. If the tip of the post were not locked under the catch edge of the hole, hinge 28H would tend to cause the flap to return to its closed, horizontal position. However since the post is locked under the catch edge, the flap is bistable, i.e., it has two stable positions: open and closed. The post is sized so that when the flap is rotated so that it extends down at an acute angle totop surface 18 of the spout, and the post is subtended bytop surface 18 andflap 28F, the tip of the post will contact the catch edge ofhole 26′, so that the flap will remain in the open position. -
FIG. 3C shows a side, sectional, detailed view of the portion of thelid containing valve 28 as taken alongline 3C-3C ofFIG. 3B . Again note thatflap 28F is bent down at livinghinge 28H, creatinghole 26′. Note also that the tip ofpost 28P is locked under the front or catch edge ofhole 26′. -
FIG. 4 —Part-Side-Sectional Views of Lid with Closing Valve -
FIG. 4 is a side sectional view of the lid ofFIG. 3A showing the valve returning to its closed position. When a user pushes in onwall 16 with afinger 30 as indicated, the portion of the wall contacted byfinger 30 is deformed or pushed in as indicated. This causes the top portion of the wall above the finger and the adjacent part ofridge 18 including the catch edge ofhole 26′ to be deformed outwardly as indicated. This will allow the tip ofpost 28P to slip up past the catch edge as also indicated.Flap 28F is shown in the process of rotating back to its horizontal or closed position. Livinghinge 28H will cause the flap to rotate or spring back until it is substantially closed and coplanar withridge 18, as shown inFIGS. 2A to 2C. - Operation
- Valve Closed: The inventive lids are supplied with their
valves 28 in the closed state (FIG. 2A ).Valve flap 28F is coplanar with its seat, which is part ofupper rim 22. The flap will normally have this position, or bent or rotated slightly upwardly to a position just above its seat (not shown) after it is cut in the punching die. If after punching it is rotated to a position just above the seat, it can be pushed down in the die so that it is coplanar with its seat as shown inFIG. 2A ; this will enable the user to push down the flap to open the valve more easily. (It can also be pushed lower, as discussed infra in connection withFIG. 5 .) - A cup (not shown) is filled with a beverage, either at a beverage store, a home, a vendor, etc. and the lid is snapped down over the rim of the cup. The user or drinker carries the lidded cup away, e.g., to a place of employment, a vehicle, a work site, etc. Since the valve is closed, the lid is substantially entirely closed so that the beverage within will not splash out, despite rough handling. Also, the escape of heat (or the entrance of heat if the beverage is chilled) will be reduced.
- Valve Opening: To drink the beverage, the user merely pushes post 28P down with a finger or thumb (not shown), causing
flap 28F to rotate downwardly onhinge 28H. When the flap rotates far enough, the tip ofpost 28P will snap past the front or catch edge ofhole 26′ as shown inFIGS. 3A to 3C. Whilehinge 28H will urgeflap 28F to re-close, the flap will not be able to do so and it will remain in the open position (FIG. 3 ) sincepost 28P is locked belowridge 18 and the catch edge ofhole 26′. The flap will thus remain stably in the open position. The user (not shown) now places their lips aroundspout 24 and drinks from the cup, throughopen hole 26′. The beverage will flow freely throughhole 26′,past flap 28F and itspost 28P, into the user's mouth. - As an added benefit, the valve provides splash resistance even when the drink hole is open. When the valve is open, as shown in
FIG. 3B , hingedflap 28F and post 28P act as a splash guard on the inside of the lid to block some liquid from splashing through opening 26′. - Valve Closing: if the user wishes to interrupt their drinking before consuming all of the beverage in the cup, they can close
valve 28 as follows: As shown inFIG. 4 , the user uses afinger 30 to push inwardly onwall 16, belowridge 18. This causes this portion ofwall 16 to deflect inwardly as shown, which in turn causes the upper part ofwall 16 and front and catch edge ofhole 26′ to distort outwardly far enough to allow the tip ofpost 28P to slip upwardly, past the front edge ofhole 26′ so thatflap 28F closes andre-seals opening 26′. Thus the cup can now be carried and handled without its beverage splashing out and reducing the transmission of heat thoughhole 26′. The user removes theirfinger 30 fromwall 16, allowing the wall to return to its normal, undistorted conformation and allowinghole 26′ to return to its normal conformation. - I presently believe the following explanation is correct, but do not wish to be bound by it. I believe that the upper part of
wall 16 and front and catch edge ofhole 26′ distort outwardly when the user pushes inwardly at the lower part ofwall 16 becausewall 16 acts as a lever whose fulcrum is between the point where force is applied and the top of the wall. The fulcrum is created by the stiffness of the lid due to its circular shape. - There are other ways to close hinged
flap 28F, in addition to the method described above. Drinkspout 24 can be squeezed or rolled between a finger and thumb. This will distort this portion of the lid and thereby release the post from the catch edge and allow the flap to close. Alternatively the user can remove the lid from the cup and push the underside of the flap up with a finger to close the flap. The user can then reattach the lid to the cup. - Valve Re-Opening When the user desires to drink again, they push post 28P down to open the flap again.
Post 28P will again be locked under the catch edge ofhole 26′ since the hole has returned to its original conformation. -
FIG. 5 —Valve Flap Pushed Below Seat - As stated, the lids may be formed with
valve flap 28F coplanar with its seat as shown inFIG. 2A , or just above its seat (not shown). However I have found that users find it easier to push down the flap to the open position (FIG. 3C ) if the lids are supplied with the flap bent down to a position just below the seat, or top surface of the spout, as shown in the fragmentary view ofFIG. 5 . This position can be created at the time the lid is formed in the punching die (not shown) by providing the female die with a spring-loaded stripper pin (not shown, but well-known to those skilled in the art) to push the flap slightly downward, below its seat after it is punched. The flap will self-rotate upwardly to this position after it is pushed down lower and released since itshinge 28H will rotate it upwardly until its edge contacts the edge of its seat, which will stop it. - When the lids are supplied with the flap in this position (
FIG. 5 ), the fluid within will not splash out since the valve is still closed. However the user can push it down to the open position (FIG. 3C ) very easily since it is already below its seat. The open valve can be closed and returned to the closed state ofFIG. 5 in the same manner discussed above. - Accordingly the reader will see that, according to the invention, I have provided a drinking cup lid with a drinking orifice that (1) improves upon prior-art lids, (2) does not require the use of tape to close the drink hole, (3) is easily resealable, (4) does not interfere or hinder with the user's drinking, (5) does not have any part that drips when opened, (6) uses a relatively small amount of material, (7) requires little time, materials, and labor to use, (8) is simple, reliable, economical, and facile to use, (9) covers the drink opening completely until it is opened by the user, (10) once opened will remain in a stable open position until closed by the user, (11) can be re-closed by the user, (12) is made from a single piece of material, (13) can be opened and closed with a one-hand operation, (14) is sanitary, (15) is integrated into a standard style of lid with a raised drink through spout configuration, (16) the user can more easily use for drinking through the lid, and (17) is more resistant to splashing when the drink hole is open.
- While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but as exemplifications of the presently preferred embodiments thereof. Many other ramifications and variations are possible within the teachings of the invention. For example, the material, size, and plastic forming method can be changed. The valve need not be on the top surface of the spout, but instead can be on a side surface. The post can be glued on, rather than being stamped from the flap. In lieu of the post, a nubbin, mound, or other protrusion can be used. The shape of the flap can be changed to oval, circular, triangular, rectangular, etc. The flap can be hinged to the outer edge of the hole, or a side edge, rather than the inner edge. In this case the release point would be on the inside or side surface of the spout. The flap can be larger than the drink-through opening so that when closed it will lie adjacent, either slightly above or below the top surface of the spout, but not coplanar with the top surface. The arrangement for attaching the lid to the cup can be changed to, e.g., screw-on, glue-on, etc. A recess in the lid need not be provided; instead the top of the lid can be flat with an upstanding valved spout. The lid can have shapes other than circular, such as oval, rectangular, triangular, polygonal, etc. The lid can be used for cold beverages and for containers for substances other than beverages, i.e., containers for non-potable liquid and particulate products. Embossed lettering, such as the word(s) “push” or “push down” can be embossed or debossed into the surface of the raised drink spout on either side of the valve to instruct the user on how to open the lid. Similarly embossed lettering such as the word(s) “push”, “push here” or “push here to close” can be embossed or debossed into the front surface of the lid along
wall 16 just below the value to educate the users on how to reclose the lid. In addition an embossed button, semi sphere, or bump can be formed at this location onwall 16 to facilitate closing of the flap more easily. - Thus the scope of the invention should be determined by the appended claims and their legal equivalents, and not by the examples given.
