Application 29, 1940, Serial No. 354,672
12 Claims. (Cl. 222-505) This invention relates to improvements in a dispenser, particularly adapted for dispensing beverages under pressure and designed especially for dispensing whipped cream. Cream and the like, canned under pressure with nitrous oxide or some other inert gas, absorbs the gas and when the pressure is released the bubbles of gas forming in and escaping from the cream whip the cream and this principle is now being used in dispensing whipped cream at soda fountains and elsewhere. The dispenser herein disclosed is particularly adapted for such service.
It is the primary object of the invention to provide a novel, simple and convenient dispensing apparatus peculiarly adapted to be incorporated in a crown cap to provide a valve therefor and means for operating the valve for dispensing the contents of the container to which the crown cap is adapted. It is a further object of the invention to provide like-apparatus which may be built into a container which does not have a crown cap.
- Other objects will appear from the following disclosure.
In the drawing:
Fig. 1 is a view in vertical section through a dispensing device provided with a crown cap embodying my invention, the dispensing tip and valve operating device being likewise illustrated in section and in a position approximate to that in which it is used.
Fig. 2 is a detail view showing in perspective the separate parts comprising the crown cap, the
valve, and the operating mechanism.
Fig. 3 is a view in perspective showing on a reduced scale the dispensing container and dispensing fitting associated in the position in which they are to be used.
Fig. 4 is an enlarged detail view showing a preferred embodiment of the invention as incorporated in a crown cap. Fig. 5 is a fragmentary detail view similar to the upper portion of Fig. 1, showing a modified embodiment of the invention in which the valve mechanism, operable by the same dispensing fitting shown in Fig. 1, is incorporated directly into the container.
Like parts are identified by the same reference characters throughout the several views.
The container 1 may comprise an ordinary can having a tapered top 8 provided wtih an apertured mount 9 beaded at It to receive the crown cap l5.
As shown in Figs. 1 and 2, the crown cap l5 t is provided with the usual cork gasket at it to closed, corresponding to conventional practice which is usually made of cork composition and impregnated with wax or the like so that it is somewhat adhesive. This adhesive quality of the gasket is taken advantage of to connect temporarily to the gasket a perforated disk I! which is made of extremely light metal such as foil.
Loosely fitting within the central opening it of the gasket is a valve 20 which may be made of or surfaced with rubber. Preferably it comprises a light wafer 2| of metal and a rubber disk 22 mounted thereon. The pressure of the contents of container 1 holds the valve 20 tightly to the inner surface of the crown cap [5 to cover the orifice 23 through which the contents of the container are dispensed. Aside from this orifice the crown cap and its gasket are otherwise of entirely conventional design.
The dispensing fitting 25 comprises a cupshaped member applicable over the top of the crown cap and having a dispensing tube at 26 opening within an interior gasket 21. Projecting through the gasket immediately adjacent the opening into tube 26 is a pin 28 of sufficient length to be adapted to reach through the orifice 23 of the crown cap and to displace the valve 20 in the interior thereof.
When the crown cap is applied to the container l the apertured wafer I1 is clamped and permanently confined between the gasket Hi of the crank cap and the mouth of the container. Pending such application the apertured foil wafer II adheres to'the gasket It with sufiicient tenacity to hold the valve in place and to maintain the parts assembled to the crown cap.
As above indicated, the gas pressure of the contents of container 1 maintains the valve normally seated to close the orifice 23, but when the prong 2B displaces the valve, the container being held in an inverted position as shown in Fig. 3, the cream will escape through the apertures IQ of the wafer l1 and about the valve, and will pass through the orifice 23 of the crown cap and I through the. interior of gasket 21 of fitting 25. Thereupon the whipped cream will be dispensed through the tube 26. The dispensing operation will continue only so long as suflicient pressure is exerted by the operators fingers upon the fitting 25 to keep the valve 2o displaced. As soon as the pressure on fitting 25 is relievedthe valve 20 will reseat itself and cut oil the discharge of cream from the nozzzle.
In the device shown in Fig. 4, which illustrates the preferred embodiment of the invention, the crown cap I5 is identical with that above disexcept for the provision of the orifice at 23. In this device, the apertured wafer I" which serves as a retainer for the valve instead of comprising a disk adhesively connected to the gasket i6 and confined between the gasket and the mouth of the container, is here made in the shape of an inverted hat provided with a flange at 29 which is held between the gasket l8 and the crown cap The depressed central portion of the wafer re ceives the valve 220 and has apertures at l9 to permit access of the liquid in the container. The fitting through which dispensing occurs is identical with that previously described, and it will be apparent that the prong 28 inserted through orifice 23 will displace the valve 220 to permit the escape of liquid from the inverted container through the nozzle tube 28 of the fitting 25.
It is possible to build the valve structure directly into the container as shown in Fig. 5, where the container Ill has a double wall top comprising an inner portion 8| and an outer portion 82. The inner portion BI is spaced at 83 from the portion 84 of the outer wall at the top, leaving a clearance within which the valve 20 is disposed. The
inner wall portion 83 has apertures I90 corresponding to the apertures IS in wafer II. The outer wall portion 84 at the top of the container has an orifice at 230 corresponding to the orifice above described at 23 in the crown cap.
The same type of dispensing fitting 250 is applicable to this structure, the only difierence being that the body portion is preferably flared at 30 sufiiciently to fit the taper of the outer wall portion 82 at the top of the container so as to facflitate handling during the discharge of the liquid contents in the manner shown in Fig. 3. In each embodiment of the invention it is preferred that the inner form of the dispensing fitting should be complementary to that of the dispenser or the crown cap of the dispenser, as the case may be. It will be understood that where the dispenser is provided with a cap the cap may be regarded, for some purposes, as a part of the dispenser.
