second embodiment

[0019]FIG. 2 provides an exploded perspective elevation view of the invention for cooling a beverage bottle 30 with a disposable self-cooling jacket 33 that is sandwiched between an insulating layer 18 and the bottle 30. The exterior of the insulating layer 18 is suitable for printing on and thus serves also as the product label 32. The cooling jacket 33 has an upper compartment with a liquid 22 and a lower compartment with a reactive solid 34. A membrane 25 separates the two compartments until deliberately ruptured. Preferably, the membrane 25 may be ruptured by a pull string 26, or alternatively by firm pressure where membrane 26 is a pressure-sensitive membrane. Massaging the insulating layer further mixes the two ingredients causing an endothermic physical or chemical reaction that cools the beverage in the bottle 30. Water is the typical liquid ingredient 22, and examples of acceptable solids are urea and ammonium nitrate, but many others also are acceptable. For product design...

third embodiment

[0020]FIG. 3 depicts the invention illustrating in a sectional elevation view a reusable portable method of heating the contents of a baby bottle 12. A flexible polymeric pouch 20 is attached at the outer surface to a thin flexible outer foam layer 18 that insulates and holds the pouch and its liquid contents 28 in close contact to the outer surface 16 of the bottle 12. A hook and loop fastener 19, such as Velcro®, along the two lateral vertical edges of the foam layer 18 enable easy securing and removal of the two layers to the bottle surface 16. Accessible through a small window, not shown, in the outer foam layer 18 is a flexible activation disk 38 that triggers a phase change of the super-cooled liquid 28. Examples of a suitable liquid and activator are disclosed in U.S. Pat. Nos. 4,077,390 and 4,872,442, and are hereby incorporated by reference. Aqueous sodium acetate solution would be a preferred liquid. Upon activation by manually flexing activator 38, the solution rapidly st...

Abstract

A portable temperature changing apparatus for containers includes a cylindrical annular moisture-proof pouch divided into a first compartment filled with a liquid and a second separate compartment holding a solid material capable of producing an endothermic or exothermic reaction upon mixing with the liquid. The seal separating the two separate compartments can be ruptured partially, when desired, enabling communication of the liquid with the solid to activate the temperature altering reaction. A flexible foam insulating layer surrounds the exterior of the annular cylindrical pouch providing insulation, damage protection, and labeling.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This patent application is related to and claims priority from U.S. Provisional Patent Application Ser. No. 60 / 883,546 filed Jan. 5, 2007.FIELD OF THE INVENTION[0002]The present invention relates, in general, to portable methods of heating and cooling beverages and, more particularly, this invention relates to outer wraps of chemicals which when forced to mix or change phase can either heat or cool the contents of the beverage container.BACKGROUND OF THE INVENTION[0003]Prior to the conception and development of the present invention, mothers traveling with infants have had to search for sources of heat to warm a baby's bottle. Or those wanting a cold beverage would need ice or refrigeration to cool a beverage down. Ice or gel packs will eventually melt or warm up, thus they provide only a temporary solution. There are numerous methods or devices disclosed in the prior art literature for on-demand heating and cooling of beverages.[0004]U.S....
