INVENTOR. SEYMOUR BREAKSTONE BY Afforney Patented Dec. 25, 1951 VALVED CLOSURE PLUG FOR INSERTION IN THE NECK OF A BOTTLE Seymour Breakstone, Chicago, Ill. Application April 15, 1946, Serial No. 662,351

1 Claim. 1

This invention relates to devices for aerating and dispensing whipping cream.

It is customary to produce whipped cream by dispensing whipping cream under pressure through a rather fine nozzle. Liquid whipping cream is placed into a container and the head space above the whipping cream is filled with gas under appropriate pressure. The liquid cream is adapted to be discharged into the atmosphere through a nozzle. When this occurs the cream becomes aerated and in effect whipped as it leaves the nozzle.

It is one of the objects of the present invention to provide a dispenser suitable for whipping cream which dispenser has a self-sealing closure valve through which may be injected a filling tube for placing into the container either the whipped cream or gas under pressure, or both, and which may then be removed and leave the container sealed and under pressure, the arrangement being such that a valve nozzle may thereafter be inserted through the bottle cap for facilitating the discharge of the liquid contents. It is one of the objects of the present invention to provide an improved closure cap for bottles of the above mentioned character. It is a still fur ther object of the present invention to provide an improved shut-off valve for bottles of the above mentioned character.

The attainment of the above and further objects of the present invention will be apparent from the following detailed description taken in conjunction with the accompanying drawing, in which Figure 1 is a top view of a container embodying the present invention;

Figure 2 is a longitudinal sectional view through the container;

Figure 3 is a fragmentary top view of the container with a dispensing valve in place; and

Figure 4 is a bottom view of the closure cap.

The present invention is particularly designed for the provision of appropriate containers which may be properly filled at a distance from the ultimate user, transported to him in any suitable manner, and then be stored on ice until the time of use. At the desired time the user may insert a dispensing valve through the closure into the container and use as desired. As such use may be in the home, with all the contents not being used at one time, provision has been made so that the dispensing valve may be removed for cleaning, etc., while the unused contents may again be stored on ice.

Referring to Figure 2, a glass bottle or container II has been provided, glass being preferable in order that the user may ascertain readily the amount of contents on hand. The bottle is provided with a hollow neck terminating in an opening surrounded by a lip I2. A metal closure cap, of the crown cap type, indicated generally as I2, is utilized on the top of the bottle II, being provided with the usual crimped edge I3 to allow easy removal from the bottle. I

The metal cap I2 has a rubber insert I4 which is secured to the inside of the cap and which has a projecting portion I6 which extends within the neck of the bottle I I and fits tightly therein. The extremity of the insert I4 is formed of a projecting portion I! having a smaller diameter than the portion Hi.

The metal cap I2 is provided at the center thereof with a small circular opening I8. The in sert I4 is provided with an aligning circular opening I9 which extends only partly through the projecting portion I6, the opening I9 terminating in a self-closing valve comprising straight line out or slit 2| extending through the remainder of the portion I6 and through the portion H.

In use, a closing cap -I2 is capped on the top of a clean sterilized bottle II. Thereafter a filling tube may be inserted through the opening I8 in the cap I2, and through the opening I9 in the insert I4. By applying pressure to the filling tube it may be forced through the straight line out or slit 2I' in the projecting portions I6 and II, the rubber expanding sufliciently to allow it to pass therethrough while making a sealing fit around the tube. The bottle may be partially filled with whipping cream to a suitable level 22 before the cap is applied, or through the filling tube after application of the cap. The remaining space 23 in the bottle is then filled with a suitable gas, such as nitrous oxide, under pressure, which is introduced through the filling tube. The filling tube may be withdrawn. The resilience of the rubber closes the straight line out or slit 2| in the insert I4, with pressure exerted from within the bottle I I on the side of the projecting portion I! aiding such closure. The filled bottle may now be transported and stored until it is desired to use the contents thereof.

The contents are removed through an appropriate dispensing valve, indicated generally as 26 in Figure 3. The valve includes a cylindrical body portion 2! divided into two sections or chambers by a partition 28. A spout 29 extends from the upper section and a tube ill from the lower section.

A plunger 34 having a stem portion 36 and a larger diameter valve head 37 extends within the body portion '27, passing throughsuitable openings in the top and in the partition 28. A

of. pressure the tube 3| may be pushed through the straight valve slit 2| in the portions I8 and H, the rubber expanding, as was previously described. However, no pressure will escape at this time, as the plunger 34 will be in. its-upward position and the valve 32 will-be-closed. The bottle ll may then be tilted or inverted, the spout 29 positioned lowermost. As finger pressure is applied to the plunger 34 the valve head 3.! will be moved away from the under .side of the partition 21, thus uncovering the opening in the partition '2]. Whipping cream underpressure will now be forced through the tube 3|, the opening in the partition 28 through which the stem 38 passes, and out of the spout 29. When the .cream under pressure issues to the atmos: phere it issues as whipped cream.

After a sufiicient quantity of the contents has been dispensed the plunger 34 will be released and the bottle ll returned to its original posi-- tion. The valve head 37 will engage the under side of the partition 28 forming a seal.

The valve 26 may now be removed from the bottle I I, the rubber insert sealing itself upon removal of the tube 3!, as was described previously. The bottle I! may now be stored on ice for future use and the valve 26 may be washed to be inreadiness for future use.

After the contents has all been used the cap 12, may be removed, by any suitable bottle opener. It may be reused or thrown away, or the rubber valve insert may be-reused. v

In compliance with the requirements of the patent statutes I have here shown and described a preferred embodiment of my invention. It is, however, to be understood that the invention 4 V is not limited to theprecise construction here shown, the same being merely illustrative of the principles of the invention. What, I consider 7 new and desire to secure by'Letters Patent is:

A valved closure plug for insertion into the neck of a bottle, said plug comprising a yielding cylindrical rubber body having a peripheral flange at its upper end and having a substan- 'tially smaller diametercylindrical projection at its lower end, a self closing slitextending through thecylindrical projection and into the body of the plug and extending through a substantial portion of the body of the plug above the projection and terminating at its top in an enlarged opening which opens at the top of the closure plug, the lower cylindrical projection at the bottomof the plug constituting a valve forcing the bottom'of the slit radially inwardly to the closed position by the action of the pressure of the surrounding atmosphere when the pressure at the bottom of the plug is greater-than the pressure at the top of the plug, the plug: being solid above the cylindrical projection and the slit surfaces being in contact with each other in the part of the-rubber body above the projection, whereby the rubber above the top of the projection prevents upward flexing of the rubber of the projection at the slit thereof.
