This application is a continuation in part of my pending application Serial No. 11,881, for Liquid Dispenser, filed February 28, 1948, now abandoned.

The invention herein has relation to a device for dispensing liquid substances. In the disclosure as made, the 'device is especially useful for the purpose of dispensing cream.

In the accompanying drawings forming a part of this specification,

Fig. 1 is an elevational view of a liquid dispenser made according to the invention as when applied to use;

Fig. 2 is a vertical central sectional view of the liquid dispenser, taken on line 22 in Fig. 1;

Fig. 3 is an enlarged fragmentary vertical central sectional view corresponding with the disclosure of a midportion of Fig. 2;

Fig. 4 is a view generally similar to the disclosure of Fig. 3, but showing parts in different positions; and

Fig. 5 is a detail sectional view, taken as on line 5-5 in Fig. 3.

A supporting frame of or for the liquid dispenser is constituted as an annular member I0 retained by a supporting stand in such manner that an opening through said annular member will be vertically disposed. As disclosed, a supporting stand for the frame or annular member It] consists of a base [I to be rested on a horizontal surface and an upright l2 integral with said base and also integral with said frame or annular member. The supporting frame or annular member I!) defines or provides a horizontal upwardly facing annular surface l3 surrounding the upper end of the vertical opening through said frame or annular member, a lower portion of said vertical opening is of reduced diameter by reason of the provision of an interiorly extending annular flange l4 upon the lower end of the frame or annular member, and said annular flange I4 defines or provides a horizontal upwardly facing annular surface I5, within said frame or annular member and in spaced, concentric relation to the annular surface I 3, surrounding the upper end of the portion of the vertical opening which is of reduced diameter.

A holder for a vessel, such as a cream bottle t6, having liquid substance to be dispensed consists of an upper hollow cylindrical portion l1, an intermediate downwardly tapering annular portion [8 and a lower interiorly extending annular flange portion [9 adapted to be squarely rested upon the annular surface I 3 of the supporting frame or annular member H) when said 7 Claims. (01. 222-183) holder is situated above and in vertical alinement with the opening through said frame or annular member.

A lifter 20 adapted to be manually actuated to cause a valve member 2! of the liquid dispenser to be elevated is constituted as an annular element 22, loosely slidably fitted, against the possibility of rotative movement, in the lower reduced portion of the vertical opening through the supporting frame or annular member In, having an exteriorly extending annular flange 23 upon the upper end thereof adapted normally to rest upon the annular surface l5 of said frame or annular member I0. The annular element 22 of the lifter 20 is as disclosed cut away, as at 24, at opposite sides thereof, and the lower end of said annular element 22 is open and integrally supports a usual piece, disposed below the elevation of the supporting frame or annular member II], to be engaged in the accomplishment of actuation of said lifter.

The lower interiorly extending annular flange portion IQ of the vessel or bottle holder provides or defines an upwardly facing annular surface 25, within said vessel or bottle holder and opposite the surface of said annular flange portion rested upon the annular surface I 3, :for supporting an exteriorly extending annular flange 26 integral with a cup shape housing 21! of the liquid dispenser.

The housing 21 additionally consists of an intermediate portion constituted as a hollow cylindrical member 28 open at its upper end and a lower portion constituted as a closure wall 29 for the lower end of said hollow cylindrical member. The hollow cylindrical member 28 is loosely situated in the upper portion of the lifter 20 and a lower part of said hollow cylindrical member extends downwardly to position below the lower end of the supporting frame or annular member I0. An outer annular part of the closure wall 29 slants downwardly and inwardly and is substantially of conical configuration and a fiat central part 30 of said closure wall, above and in spaced relation to the lower end of the lifter,

2D, is disposed in perpendicular relation to the hollow cylindrical member 28.

The valve member 2| includes an upper portion constituted as a hollow cylindrical element 3| slidably fitted to the interior surface of the hollow cylindrical member 28 and a lower portion constituted as an ordinary valve 32. The upper end of the hollow cylindrical element 3| integrally supports an internally extending annular flange 33, and vertical straps 34, extending downwardly from the inner margin of said annular flange 33, integrally support the valve 32. Said valve is situated below the lower end of the cylindrical element 3| within a dispensing or measuring chamber 35 provided by the lower part of the hollow cylindrical member 28 and the closure wall 29. The flat central part 39 of said closure wall 29 is provided with a discharge orifice and the valve 32 includes a conical valve element adapted to be engaged with and removed from an annular valve seat provided by the flat central part 3i) in surrounding relation to said discharge orifice.

In practical operation of the liquid dispenser, the valve member 21 is manually slid upwardly in the cup shape housing 21 to cause the valve 32 to be removed from the valve seat and slid downwardly by gravity to cause said valve to be engaged against said valve seat. As disclosed, an upper portion of the hollow cylindrical element 3| of said valve member 21 integrally or rigidly supports diametrically opposed, exteriorly extending actuator pieces or lugs 31 which project through and are slidable in vertical slots 38 in the upper portion of the hollow cylindrical mem ber 28 of the cup shape housing 21. Outer end portions of the actuator pieces or lugs 3'! are disposed above the annular flange 23 of the lifter 20, and the construction and arrangement are such that the valve 32 will be lifted from its seat, as in Fig. 4 of the drawings, in response to raising of said lifter and permitted to return to its seat, as in Figs. 2, 3 and 5, by gravity with lowering of the lifter.

The exteriorly extending annular flange 26 integral with the cup shape housing 2'! carries an upwardly extending annular flange 39 which is integral with the outer margin of said exteriorly extending annular flange, and a supporting member, constituted as a gasket Ml, for a vessel or bottle is situated within the upwardly extending annular flange 39 and rested upon the upper surface of the exteriorly extending annular flange 2%. As disclosed, the supporting member or gasket 4%) is composed of rubber. It could, however, consist of any material suitable to its purpose. An upwardly facing intermediate annular surface 4| of said supporting member or gasket merges at its outer margin into an upwardly and exteriorly extending annular surface provided by an annular flange 42 supported by the internal surface of said upwardly extending annular flange 39 and at its inner margin into an upwardly and interiorly extending annular surface provided by a conical plug 13 situated above and in alined relation to the cup shape housing 21. An annular projection M on the supporting member or gasket 40 extends downwardly from the central portion of said supporting member or gasket, and a central opening 45 extending through the supporting member or gasket 40 is contiguous at its upper end with the upper end of the conical plug :13 and at its lower end with the lower end of the annular projection 44. An annular trough as between the conical plug 43 and the annular flange i2 is adapted to receive the open end of a vessel, such as the bottle l6, into the open end of which said conical plug is adapted to project to provide an annular seal precluding the passage of liquid substance from the vessel or bottle into the liquid dispenser other than liquid substance which passes downwardly through the central opening 45. Inasmuch as the plug it is conical, it is capable of being sealingly fitted to the open ends of vessels or bottles which vary in diameter.

A tubular member M, for conveying liquid substance from position above the supporting member or gasket Iii! into the cup shape housing 21, has its upper end portion frictionally and removably supported upon the annular projection 2 5 of the supporting member or gasket 5%, and said tubular member extends downwardly into the valve member 2|. The tubular member cl has diameter considerably less than that of the hollow cylindrical member 28 of said cup shape housing, and as shown said tubular member and hollow cylindrical member are in concentric rela tion. The upper portion of the valve member 2| is in slightly spaced relation to the lower portion of the tubular member ll, and the lower end of said tubular member terminates in spaced relation to a fiat upper surface 48 of the valve 32 when said valve is in closed position, as in Figs. 2, 3 and 5 of the drawings.

The manner in which the liquid dispenser is adapted to function will be apparent. Upon manually raising the lifter 29, as by employment of a container for receiving a measured quantity of liquid substance from the dispensing or measuring chamber 35 placed beneath said lifter, the valve member 2| will be slid upwardly to cause the valve 32 to be removed from the annular valve seat surrounding the discharge orifice 3% and the flat upper surface '28 of said valve to become engaged against the lower end of the tubular member 4? in sealing relation thereto. Assuming the dispensing or measuring chamber 35 to be loaded with liquid substance when the.

valve member 2! is slid upwardly, the contents of said chamber will be removed by gravity from the liquid dispenser by way of the discharge orifice 36. The flow of liquid substance into the dispensing or measuring chamber will be prevented while the valve 32 is open by reason of the fact that the flat upper surface 48 is engaged against the lower end of the tubular member ii. Upon release of the lifter 233 after each manual actuation, gravity will cause the valve member 2i to be slid downwardly to cause the valve 32 be engaged with the annular valve seat surround-- ing the discharge ormce 36 and the flat upp r surface 68 to become removed from the lower end space 49 between the lifter 2i! and the internally extending annular flange i l and. an annular chamber 50 of the supporting frame or annular member H) surrounding the hollow cylindrical member 28 of the cup shape housing 21, and thence interiorly through the vertical slots 38 in said hollow cylindrical member. Head pressure on the liquid substance in the tubular memher 4'! and said dispensing or measuring cham ber will be insuflicient to cause liquid substance to flow upwardly to the elevation of the vertical slots 38, and tendency toward upward flow of liquid substance into said vertical slots will be resisted by atmospheric pressure communicated to the dispensing chamber by way of said annular space 49, said annularchamber 50 and the vertical slots.

The open upper end of the upper hollow cylindrical portion ll of the vessel or bottle holder is closed by a removable cover As disclosed in Fig. 2 of the drawings, a box 52 for refrigerant, ice as shown, is rested upon the closed end of the bottle I6 and situated within the removable cover 5|. Said cover is removable from the box 52, as well as from the holder, and said box is open at its top to receive refrigerant.

Attention is called to the fact that each of the vessel or bottle holder, the lifter 2!], the valve member 2|, the cup shape housing 21, the supporting member or gasket 40 and the tubular member 47 is a separate and complete entity or instrumentality. The parts of the liquid dispenser are capable of being readily and easily assembled and disassembled. There are no threaded elements or positive connections. The

vessel or bottle holder rests upon the supporting frame or annular member Ill. The cup shape housing 21 is removably seated within said vessel or bottle holder. The supporting member or gasket 40 is removably seated within said cup shape housing. The tubular member 41 is removably supported by said supporting member or gasket. The valve member 2| is slidably disposed in the cup shape housing 27 and removable therefrom. The lifter 20 is slidably and removably disposed in the reduced portion of the vertical opening through the supporting frame or annular member ID.

When the parts of the liquid dispenser are to be assembled, the lifter 20 will be inserted downwardly into the supporting frame or annular member ID. The valve member 2| will be inserted in the cup shape housing 21. The tubular member 4! will be placed upon the annular projection 44 of the supporting member or gasket 40 until the upper end of said tubular member is up against the body of said supporting member or gasket, and the supporting member or gasket, with the tubular member applied, will be fitted to the upwardly extending annular flange 39 and rested upon the exteriorly extending annular flange 26 of said cup shape housing. The vessel or bottle holder will be slid upwardly over the cup shape housing 21 until the internally extending annular flange I9 of said holder is seated against the lower surface of the exteriorly extending annular flange 255 of said cup shape housing, and, finally, the assembled unit, including all of the parts of the liquid dispenser except the lifter 20, will be associated with the supporting frame or annular member ID so that said internally extending annular flange 19 of the holder rests upon the upwardly facing annular surface 13 of said supporting frame or annular member. Disassembly of the parts of the liquid dispenser can be accomplished by reversal of the operations as described.

A vessel or bottle containing liquid substance to be dispensed will be assembled with the unit of the liquid dispenser including parts thereof except the lifter before the unit is associated with the supporting frame or annular member If). The vessel or bottle will be retained upright while assembly with the unit is accomplished, and after assembly, the unit and vessel or bottle will be grasped together and inverted and set upon the supporting frame or annular member ID.

When a vessel or bottle, either empty or loaded, is to be removed, the unit with vessel or bottle will be lifted from the supporting frame or annular member ID and turned upright so said unit can be lifted from said vessel or bottle. In an instance when a vessel or bottle being removed contains liquid substance, the valve member 2| will be elevated, by pushing the actuator pieces or lugs 3! upwardly, to position causing the flat upper surface 18 of the valve 32 to close off the lower end of the tubular member 47 after the unit is lifted and until the vessel or bottle is made upright. Elevation of said valve member will of course permit the dispensing or measuring chamber 35 to become emptied before the unit is set upright, and sealing the tubular member 4'! closed will preclude possibility of spilling of liquid substance from the vessel or bottle. Of course, the externally extending annular flange 25 on the cup shape housing 21 will be held engaged against the internally extending annular flange I9 of the holder while the unit with vessel or bottle is being removed and until said vessel or bottle is made upright.
