Self-chilling beverage container and method
An iceless method of providing a chilled beverage to a customer by supplying a container that not only contains the beverage but also contains a compartment filled with a compressed gas for selectively cooling the liquid in the container before consuming it. The apparatus is characterized by the fact that the end of the gas compartment adjacent the mouth of the beverage compartment occupies less than the entire mouth of the beverage compartment so that when the closure member is removed, a liquid contained in the beverage compartment may be conveniently poured out, whether or not the frangible cover of the gas compartment has first been punctured for releasing the gas.
This application claims priority of my U.S. Provisional Application Ser. No. 60/762,228 filed Jan. 27, 2006.
BACKGROUND OF THE INVENTIONThere are situations in which a person would like to have a cool drink, but ice or refrigeration is not available. That kind of situation is amply described in my U.S. Pat. No. 6,530,235 issued Mar. 11, 2003, entitled “Self-Chilling Portable Beverage Container Assembly, and Method”.
SUMMARY OF THE INVENTIONThe present invention is an iceless method of providing a chilled beverage to a customer by supplying a container that not only contains the beverage but also contains a compartment filled with a compressed gas, the gas compartment being closed by a frangible member, wherein the customer can conveniently puncture the frangible member to release the gas and thereby cool the liquid in the container before consuming the liquid.
More specifically, the invention provides an apparatus system in which a beverage container has an elongated configuration and forms a beverage compartment with a mouth at one end thereof. A separate compartment extends longitudinally within the beverage compartment for receiving and storing compressed gas, the gas compartment having an end adjacent the mouth of the beverage container and a frangible member that normally covers that end of the gas compartment. A closure member normally closes the mouth of the beverage compartment and also extends over the frangible cover of the adjacent end of the gas compartment. The end of the gas compartment adjacent the mouth of the beverage compartment occupies less than the entire mouth of the beverage compartment so that when the closure member is removed, a liquid that is contained in the beverage compartment may be poured out whether or not the frangible cover of the gas compartment has first been punctured for releasing the gas in order to cool the liquid in the container.
As shown in
A closure member 30 normally closes the mouth of the beverage compartment 12 and also extends over the frangible cover 25 of the adjacent end of the gas compartment. Closure member 30 is preferably threaded to the top of container 10. The end 22 of the gas compartment occupies less than the entire inner area of the mouth of the beverage compartment. When the closure member 30 is removed, as shown in
A puncturing device 50 is normally secured inside the closure member 30, and is operable after removal of the closure member for puncturing the frangible cover of the gas compartment.
In the alternate embodiment of
A significant feature of my invention is that the end of the gas compartment within the mouth of the beverage compartment occupies less than the entire width of the mouth of the beverage compartment, so that when the closure member or cap is removed, a liquid contained in the beverage compartment may be poured out whether or not the frangible cover of the gas compartment has first been punctured for releasing the gas and thereby cooling the liquid in the container. In other words, the beverage container may still be used either as an iceless container for a cooled drink, or for a drink that is not cooled.
While the presently preferred embodiment of my invention has been disclosed in detail in order to comply with the requirements of the patent laws, there are possible modifications and alternative forms that would be understood by those persons skilled in the art. The scope of my invention, therefore, is to be limited only in accordance with the appended claims.

Claims
1. An iceless method of providing a chilled beverage to a customer by supplying a container that not only contains the beverage but also contains a compartment filled with a compressed gas, the gas compartment being closed by a frangible member, and wherein the customer punctures the frangible member to release the gas and thereby cool the liquid in the container before consuming the liquid.
2. An apparatus for providing a chilled beverage to a customer, comprising:
- a beverage container for not only containing the beverage but that also has a compartment to be filled with a compressed gas;
- the gas compartment being closed by a frangible member; and
- the apparatus being adapted for the customer to puncture the frangible member to release the gas and thereby cool the liquid in the container before consuming the liquid.
3. Apparatus as in claim 2 which further includes a puncturing device adapted to operate cooperatively with the beverage container for puncturing the frangible member.
4. Apparatus as in claim 3 wherein the puncturing device is not normally attached to the beverage container.
5. Apparatus as in claim 3 wherein the puncturing device is normally attached to the beverage container.
6. An apparatus system for providing a chilled beverage to a customer, comprising:
- a beverage container having an elongated configuration and forming a beverage compartment with a mouth at one end thereof;
- a separate compartment extending longitudinally within the beverage compartment for receiving and storing compressed gas, the gas compartment having an end adjacent the mouth of the beverage container and a frangible member which normally covers that end;
- a closure member normally closing the mouth of the beverage compartment and also extending over the frangible cover of the adjacent end of the gas compartment; and
- the end of the gas compartment adjacent the mouth of the beverage compartment occupying less than the entire mouth of the beverage compartment so that when the closure member is removed, a liquid contained in the beverage compartment may be poured out whether or not the frangible cover of the gas compartment has first been punctured for releasing the gas and thereby cooling the liquid in the container.
7. Apparatus as in claim 6 which additionally includes a puncturing device normally secured inside the closure member and operable after removal of the closure member for puncturing the frangible cover of the gas compartment.
8. Apparatus as in claim 6 which additionally includes a puncturing device normally separate from the beverage container and which is operable after the closure member has been removed for puncturing the frangible cover of the gas compartment.
