Abstract
A washing system for dispensing a liquid cleanser or lotion includes a housing enclosing a first and second reservoir, a tube system for connecting in fluid communication the first and second reservoirs to a manual valve that is located on or outside of the housing. The first reservoir comprises a collapsible, airtight bag containing liquid cleanser or lotion, and is located above the second reservoir, such that soap or lotion will flow into the second reservoir from the first reservoir due to gravity when the first reservoir bag is installed. The second reservoir provides additional liquid storage for use between replacement of the first reservoir.
Description
- This invention relates to systems for dispensing soap or lotion. Soap and lotion dispensers add convenience to users of both public and private restrooms by allowing users to operate a manual valve to dispense an appropriate amount of soap or lotion onto the user's hands. The manual valve can be a pump or an on/off type valve.
- Such soap or lotion dispensers include a reservoir for holding an amount of soap or lotion to be dispensed that can be refilled or replaced when the soap or lotion is entirely dispensed. Frequently, soap or lotion is entirely dispensed before the owner of the dispenser has time to refill or replace it so that when the manual valve is operated by a user, no liquid is dispensed. Further, since the soap or lotion is emptied from the pipes or tubes when the reservoir is emptied, the pipes must be reprimed when refilling the liquid. This priming process adds to the time that the soap or lotion cannot be dispensed.
- Also known in the art are liquid dispensing systems that use a “bag in the box” arrangement. In these dispensing systems, soap or lotion fills the inside of an airtight bag, which in turn is placed inside a box. As the liquid is dispensed, the bag collapses within the box. When the bag is emptied, the box may be thrown away and a new box of liquid can be attached. These systems avoid the messiness of refilling the reservoirs, but usually are not replaced until all of the liquid is gone. Otherwise, the extra liquid is wasted. Therefore, if another box of soap or lotion is not immediately installed, an interim time exists when the dispenser will not dispense any liquid. Alternatively, to avoid this inconvenience to the users, janitors replace the boxes before they become empty, resulting in waste.
- Some known dispensing systems attach the manual valve through a pipe or tube to a large reservoir of soap or lotion that is hidden under the sink or in another room. An auxiliary reservoir near the first reservoir can be filled with soap or lotion at the time that the first reservoir is refilled or replaced so that the soap or lotion may be dispensed continuously. See, e.g., U.S. Pat. No. 6,129,245, incorporated herein by reference.
- It is an object of the present invention to provide a new and improved system for dispensing soap or lotion which will improve upon the current “bag in the box” system and/or earlier systems. In particular, it is an object to provide a new and improved system in which the initial and maintenance costs of the various components will be reduced, placement and storage of the system will require minimal installation or alteration of the facilities, and/or the system will provide continuous dispensing of liquid in the interim period when the reservoir of soap or lotion is being refilled or replaced.
- Other objects, advantages, features and results will more fully appear in the course of the following description.
- The washing system of the present invention includes a housing, a manual valve in the housing, a first reservoir that is replaceable, a second reservoir, and a connecting line that connects the first and second reservoirs in fluid communication with each other and with the valve. The first and second reservoirs, manual valve, and connecting line are all contained within the housing, or the manual valve can be located outside of the housing. When a new collapsible, airtight bag containing soap or lotion is installed in the housing as the first reservoir, some of the soap or lotion falls down the connecting line due to gravity. The second reservoir is below the first reservoir, and is therefore filled with the lotion or soap falling down the connecting line after the first bag is installed. Therefore, when the collapsible bag in the first reservoir is emptied, soap or lotion may still be dispensed through the valve from the second reservoir. Thus, soap or lotion can still be dispensed during the period when the first reservoir is empty. Further, when the reservoirs, connecting line, and valve are all on or within the housing, installation of the dispenser does not require bringing a tube or pipe through walls or the sink to link the reservoir with the valve or exposing tubes or pipes, nor does it require substantial storage space.

lower side wall 106 of thehousing 12 includes amantle 140 at the same distance from thefloor 116 as thelower shelf 112. - With reference to FIG. 3, the
housing 12 encloses afirst reservoir 200, e.g., a “bag-in-box”, and asecond reservoir 202. Thereservoirs upper shelf 110 and thelower shelf 112, respectively. The bag of thefirst reservoir 200 is surrounded by abox 203, although this is not necessary. Thefirst reservoir 200 includes an on/off valve 204 (shown in more detail in FIGS. 4a and b) with a central,cylindrical shaft 206, first and secondcircumferential ledges shaft 206, acap 212, andflexible arms 214 connecting thecap 212 to theshaft 206. The firstcircumferential ledge 208 is sealed to the collapsible bag by methods known in the art. The firstcircumferential ledge 208,cap 212,arms 214, and upper portion of theshaft 206 are located within thefirst reservoir 200. The lower portion of theshaft 206 and secondcircumferential ledge 210 protrudes from an opening in thefirst reservoir 200 and thebox 203. Thevalve 204 is initially in the “off” position, as shown in FIG. 4a, where thecap 212 blocks the opening to theshaft 206. - A
connector 216 includes abase 220 and a pair offingers 222 extending up from thebase 220, each finger having ahooked end portion 224. Extending above and below from the center of thebase 220 is aconnection tube 226. The tube has an upper portion and a lower portion. The upper portion of the tube has acircumferential groove 228 for receiving aseal ring 230. Thehooked end portions 224 extend upwards to clasp the secondcircumferential ledge 210 of thevalve 204, discussed in more detail below. - The
first reservoir 200 is secured to theconnector 216 by pushing thevalve 204 onto theconnection tube 226, as shown in FIG. 4b. When thevalve 204 is pressed onto theconnector 216, theconnection tube 226 pushes thecap 212 up and into the open position, thereby allowing relatively free flow of the soap or lotion from thereservoir 200 through theconnection tube 226. Further, the secondcircumferential ledge 210 on thevalve 204 is pressed into engagement with thehooked end portions 224 of thefingers 222 on theconnector 216 so that the secondcircumferential ledge 210 is beneath thehooked end portions 224. Thevalve 204 is therefore held in place relative to theconnector 216. Theseal ring 230 forms a seal for the junction of theconnection tube 226 and theshaft 206. Theconnector 216 andvalve 204 can alternatively be held together withoutfingers 222 by the friction of theseal ring 230 or by fixing theconnector 216 to the housing. - This process is performed when the
connector 216 is in the uninstalled position, i.e., outside of the dispenser, in order to lessen the stress on theupper shelf 110. After theconnector 216 and the on/offvalve 204 are installed, theconnector 216 is slid into place withincutout 128. Alternatively, the on/offvalve 204 can be coupled to theconnector 216 while theconnector 216 is secured to the upper shelf so that it cannot fall throughcutout 128. Other types of valves and/or connectors are known for permitting the flow of soap and lotion from the first reservoir and it is not intended that the present invention be limited by the type of valve or connector. For example, other types of fittings, valves, etc., may be used. Thefirst reservoir 200 can alternatively include a fitting 232 that is sealed with analuminum sealing cover 234 instead ofarms 214 andcap 212, as shown in FIG. 4c. When theconnector 216 is pushed onto the fitting 232, thealuminum sealing cover 234 is punctured, allowing flow of soap or liquid through theconnection tube 226. - Referring again to FIG. 3, the
second reservoir 202 has a flexibleplastic outlet nozzle 300 with acollar 310 extending below thelower shelf 112 and pointing in the direction of a “T” fitting 312, which projects upwards throughslot 138. After the “T” fitting 312 is installed inhousing 12, the hingedportions hinges mantel 140. Thus, hingedportions lower shelf 112. Theoutlet nozzle 300 is fixed to an outlet of thesecond reservoir 202 and can be made with any material that can form a tight seal with the “T” fitting 312. Alip 314 of a “T” fitting 312 (discussed in more detail with reference to FIG. 5) engages thecollar 310 of theoutlet nozzle 300 of thesecond reservoir 202 to form a sealed connection. A tube may also be used to connect the outlet nozzle to the “T” fitting. The outlet of the “T” fitting 312 connects throughtubing system input tube 126 leading to the pump-typemanual valve 8. Other types of fittings or nozzles are known for forming a sealed connection and it is not intended that the present invention be limited by the type of fitting or nozzle. - FIGS. 2b and 5 depict the “T” fitting 312 in more detail. The
middle tube 316 of the “T” fitting 312 has alip 314 that engages thecollar 310 of theoutlet nozzle 300 of the second reservoir 202 (FIG. 3). Onetube 318 can intake soap or lotion from thefirst reservoir 200, and thelast tube 320 can output the soap or lotion from both the first andsecond reservoirs - The first and
second reservoirs type valve 8 are coupled together by atubing system reservoirs valve 8. - The
connector 216 couples thefirst reservoir 200 to a flexibleplastic tube 324 by acable tie 322. Thetube 324 extends from theconnector 216, through theopening 128 in the upper shelf 110 (see FIG. 2a) and thefirst opening 136 in thelower shelf 112 to anelbow 328. Theelbow 328 has barbed edges (not shown) that grip the inside of the flexibleplastic tube 324, and the connection is sealed on the outside of thetube 324 by a clamp or cable tie (not shown), as is known in the art. Theelbow 328 is connected to the “T” fitting 312, e.g., by a flexible tube. The length of thetube 324 is long enough to reach theconnector 216 when it is uninstalled fromcutout 128 in order to attach it to a newfirst reservoir 200 outside of the housing. The “T” fitting 312 is located beneath thesecond reservoir 202. - The
tube 320 of the “T” fitting 312 is coupled to asecond elbow 330, e.g., by a flexible tube. Elbow 330 is coupled to aflexible tube 326, which connects to athird elbow 332. Elbow 332 is connected to a fitting 158 which is threaded into theinput tube 126 of the pump-type valve 8. Theelbows elbows - Therefore, when a
first reservoir 200 is installed to theconnector 216, soap or lotion drains from thefirst reservoir 200, through the on/offvalve 204,tube 324,elbow 328, and into the “T” fitting 312. From the “T” fitting 312, the soap or lotion re-fills thesecond reservoir 202 and thetubing system type valve 8. Thus, when thefirst reservoir 200 is empty, a continuous flow of soap or lotion from thesecond reservoir 202 is still possible before thefirst reservoir 200 is re-filled. - The pump-type
manual valve 8 shown in FIG. 6 is similar to the replaceable valve disclosed in U.S. Pat. No. 5,887,762, incorporated herein by reference. The pump-typemanual valve 8 has aninlet 50 and anoutlet 52 and comprises anouter sleeve 54, aninner sleeve 56, and aplunger 58. Theouter sleeve 54 is hollow, slides intochamber 118 and is secured by aset screw 60 that projects throughhousing 12 intochamber 118 and within aseat 62 on theouter sleeve 54. - The
plunger 58 is also hollow and slidable within theouter sleeve 54. Theplunger 58 can be held inside theouter sleeve 54 by aguide pin 64 carried by theouter sleeve 54 projecting into agroove 66 of theplunger 58 and agroove 68 ofchamber 118. A one-way valve 70 is located at the inlet end of theplunger 58 to allow soap or lotion to move from the inlet end to the outlet end. - The
inner sleeve 56 is carried inside theouter sleeve 54 and is located near the inlet end of the pump-type valve 8. Theinner sleeve 56 is urged away from theplunger 58 by aspring 72 between them. A second one-way valve 74 is located at the inlet end of theinner sleeve 56. - When the
plunger 58 is manually pressed in the direction of therear wall 108, the space between theplunger 58 and theinner sleeve 56 is compressed and the soap or lotion residing in that space is forced out of the first one-way valve 70 and out through theoutlet 52. When theplunger 58 is released, the space between theinner sleeve 56 and theplunger 58 is increased, and the vacuum formed opens the second one-way valve 74 to allow soap or lotion from theouter sleeve 54 into theinner sleeve 56. - Other manual valves can be substituted for pump-
type valve 8 with similar effect. In particular, U.S. Pat. No. 4,949,877, incorporated herein by reference, discloses a fluid dispenser valve with a relocated outer seal to seal against a cylindrical cavity, and this valve can also be used in accordance with the instant invention. Other appropriate manual valves that can be used in accordance with the instant invention will be evident to those skilled in the art. - The reservoirs and manual valve can alternatively be connected via a rigid channel. In FIGS.7-9, the
cover 18,floor 116,valve chamber 118, and side walls (not shown) are similar to those discussed in reference to the previous figures. However, an on/offvalve 400, similar to that described is reference to FIG. 4c, is fixed to the bottom rear of thefirst reservoir 410 and directed toward theback wall 412. The bottom rear of thesecond reservoir 414 is also fixed to an on/off valve 416 similar to that described in reference to FIG. 4c, and the on/off valve 416 is directed toward theback wall 412. Thevalve chamber inlet 126 is threaded to acoupling 418 that has threads on one end and barbs on the other end. - A
back wall 412 is fastened to the side walls (not shown) and includes threenozzles valves 400, 416 and the inlet of thepump chamber 126. Thenozzles surround openings 426 in theback wall 412. Thenozzles inner channel cylindrical surface pointed end portion cylindrical surface 434, 436 includesopenings 446 that lead to the cylindricalinner channel ring 448 fits around the outercylindrical surface 434, 436 to the rear of theopenings 446. Thebottom nozzle 424 includes abarbed end portion 444. - When the
back wall 412 is fixed to the side walls (not shown), the top andmiddle nozzles valves 400, 416 coming from the first andsecond reservoirs rings 448. The junction of thebottom nozzle 424 and thecoupling 418 is surrounded by aflexible sleeve 450 and thesleeve 450 is sealed by two cable ties 452, 454 surrounding thesleeve 450 at each of the sleeve's 450 ends. Thesleeve 450 can alternatively be sealed with a clamp at each end, if needed. - A
channel 456 is fastened, e.g., by welding, at its edges to the rear of theback wall 412. Aseal 458 lines the edges of thechannel 456. A outwardly-curved center portion 460 extends linearly down the center of thechannel 456 and, when thechannel 456 is fixed to theback wall 412, defines a channel linking the threeopenings 426 in theback wall 412. Above the top edge of thechannel 456, theback wall 412 includesprotrusions 462 extending horizontally to the rear of theback wall 412 to stabilize the dispenser when it is mounted on a wall. - Although FIGS. 7 and 9 describe a valve chamber inside the housing and a bottom nozzle directed toward the front of the dispenser, the bottom nozzle can be directed downward or otherwise away from the housing and the flexible sleeve can extend outside of the housing to an external pump. It should also be noted that the arrangements of tubes and fittings described in earlier embodiments may also be used in connection with external pumps, i.e., pumps not located inside of the reservoir housing.
- Although the foregoing describes the invention in terms of embodiments, this is not intended to limit the invention. Rather, the foregoing is intended to cover all modifications and alternative constructions falling within the spirit and scope of the invention.
