Abstract
A self-cooling beverage container comprising a space between outer and inner walls, the space containing a liquid that is mixed with a chemical contained within a compartment within the base of the beverage container. The compartment within the base of the beverage container has a rupture portion located within the space between the outer and inner walls, and pressure on the base of the beverage container causes the rupture portion to open, allowing mixing of the chemical and the liquid. The chemical and the liquid react in an endothermic reaction, cooling the contents of the beverage container.
Description
- 1. Field of the Invention
- The present invention relates to the field of beverage containers. More particularly, it relates to a beverage container that is self-cooling, allowing a beverage to be made cold without the necessity of an external cooling source.
- 2. Background and Description of the Prior Art
- Commercial beverage can production is a large enterprise. Canned beverages range from soda to juice to beer and mixed drinks. Canned beverages are dispensed by machines and sold by stores and venues such as baseball and football stadiums. People carry canned beverages to parks, beaches, or simply to work for lunch. However, canned beverages require cooling. This is accomplished either by using a refrigerator or ice. When going to a park or the beach, this requires taking a cooler filled with ice and beverages, adding to the amount of material that a person has to carry with them.
- Prior designs have been used to create containers that are intended to chill beverages and/or keep beverages cold. U.S. Pat. No. 5,325,680 to Baroso-Lujan for a “Self-Cooling Beverage Container With Evacuated Refrigerant Receiving Chamber” teaches a beverage can that cools a beverage within the can through a liquid refrigerant. However, the '680 patent has several drawbacks. First, it is a complex design that would make the manufacture of the can expensive and potentially not cost effective given the relatively low cost of canned beverages. Secondly, the can in the '680 patent requires the refrigerant to be pressurized in compartment of the can, while a second chamber holds a vacuum, so that when the partition between the compartments is mechanically broken, the refrigerant expands into the second chamber. Because the can requires both a pressurized chamber and a chamber that is under vacuum, the cost of manufacture increases and the can must have enough structural strength to hold the pressure and the vacuum. Finally, any potential leakage could be dangerous as the design relies upon refrigerant products that may not be safe for human consumption.
- U.S. Pat. No. 4,485,636 to Hilado for a “Container With Cooling Capability” teaches a double-walled structure with a refrigerant compartment to contain water or some other fluid that can be frozen so as to keep the container, and the beverage within it, cold. The container has a diaphragm that expands when the liquid freezes, allowing the refrigerant liquid to be frozen without rupturing the container. There are several drawbacks to this design, however. First, the container must be placed in a freezer prior to use so that the refrigerant liquid can be frozen. Second, the design cannot be adapted for use in cans that are shipped with a beverage already in them; the beverage needs to be poured into the container after the container is prepared by being frozen. In adapting such a design for sealed beverage cans from a bottling/canning company, the end user would have to freeze the container with the beverage in it—making the design unusable for such a purpose.
- U.S. Pat. No. 5,555,741 to Oakley for a “Self-Cooling Fluid Container With Internal Refrigerant Chamber” teaches a beverage can with a refrigerant chamber integral to the base of the can. The can has a second chamber and, as with the '680 to Baroso-Lujan, the second chamber contains a vacuum and the refrigerant chamber is manufactured with the refrigerant liquid under pressure. By puncturing the bottom of the vacuum chamber, the refrigerant is allowed to expand into the vacuum chamber, cooling the beverage in the same manner as the '680 patent. The '741 patent is therefore subject to the same drawbacks as the '680 patent as they relate to manufacturing a beverage container that has a pressurized compartment and a compartment that is required to hold a vacuum. In addition, the design of the '741 invention provides cooling for the beverage in a localized manner; i.e., only at the base of the container.
- What is needed, therefore, is a new design for a beverage container that is portable, and provides a self-contained cooling means without the need to freeze or chill the container or beverage first. It is also desirable to have such a container efficiently cool a beverage within by surrounding the beverage with a compartment containing a cooling liquid. It is further desirable to have a beverage container that doesn't require either high pressure refrigeration liquids or chambers that must be placed under a vacuum.
- The present invention is drawn to the cooling of beverages and, more particularly, to providing a self-cooling beverage container.
- It is an object of the present invention to provide a simple, self-contained self-cooling beverage container that doesn't require the use of external cooling means in order to chill a beverage.
- It is a further object of the present invention to provide a self-cooling beverage container that may be manufactured simply, and be used by beverage companies to contain and ship their beverages in a manner that is similar to the current means of canning and shipping.
- It is a further object of the present invention to provide a self-cooling beverage container that doesn't require toxic refrigerants to cool beverages.

FIG. 2 a is a cutaway view of a bottom portion of a can in accordance with an embodiment of the present invention. -
FIG. 2 b is a view of a push top container in accordance with an embodiment of the present invention. -
FIG. 3 is a view of an embodiment of a beverage container showing the insertion of a push top container into the bottom portion of the beverage container. -
FIG. 4 is a view of an embodiment of the present invention showing an insert with a rupture portion opened between the can and the insert. - Referring now to
FIG. 1 , a diagram of an embodiment of the present system is shown. As shown, this embodiment of the present invention comprises abeverage container 101, thebeverage container 101 having anexterior wall 102 and aninterior wall 104, theinterior wall 104 disposed within thebeverage container 101 such that afirst space 105 exists between theexterior wall 102 and theinterior wall 104. Thefirst space 105 is continuous around the exterior of theinner wall 104 with the exception of the top portion of theinner wall 104; the top portion of theinner wall 104 is joined with the top portion of theexterior wall 102 such that an opening (not shown) may be disposed in the top portion of thebeverage container 101 and a beverage drink is contained within theinterior space 103 created by theinterior wall 104. The exterior wall accepts aninsert 108, which is comprised of a hollowcylindrical portion 106 attached to abase 107; thebase 107 is attached to the bottom of thebeverage container 101. Thefirst space 105 contains a first chemical, and the hollowcylindrical portion 106 contains a second chemical. Theinsert 108 further comprises arupture portion 109, which opens when pressure is applied to the bottom of theinsert 108, allowing the first chemical to mix with the second chemical. In a preferred embodiment, the first chemical is water and the second chemical is a power form of ammonium nitrate. When mixed, the water and the ammonium nitrate react endothermically, cooling thebeverage container 101 and the contents of theinterior space 103. - The
insert 108 is show inFIG. 1 positioned within an opening 201 (FIG. 2 ) in thebeverage container 101.FIG. 2( a) shows theopening 201 within thebeverage container 101, - Referring now to
FIG. 2 , thebeverage container 101 is shown with theopening 201 shown, with theinsert 108 shown outside of thebeverage container 101. -
FIG. 3 shows the invention with theinsert 108 in position below thebeverage container 101 and oriented to be inserted 301 into theopening 201. -
FIG. 4 shows thebeverage container 101 with theinsert 108 positioned within theopening 201.Pressure 401, usually applied manually, to thebottom portion 107 of theinsert 108 causes arupture 402 in therupture portion 109. Therupture 402 allows the contents of theinsert 108 to mix with the contents of thefirst space 105, the resulting chemical reaction being endothermic and cooling the contents of the beverage container.
