A beverage container is provided with an integral cooling element to maintain a beverage at a cooled temperature after exposure to a warmer environment. The cooling element incorporates use of solid/liquid phase change material. When the beverage is chilled, the phase change material is maintained in a solid state below its melting temperature. When the beverage container is exposed to a warmer environment, such as during consumption, the phase change material undergoes a phase change thereby absorbing heat from the surrounding beverage. The cooling element can either be attached to the inside of the container or free-floating, but in either case, is in direct contact with the beverage.

Container incorporating integral cooling element

An expandable pouch for applying a pressure to a material to be dispensed from a container wherein two sheets of a fluid impervious material are permanently joined together at their edges and divided into a plurality of compartments by semi-permanent peelable strips. One of the compartments is divided into sub-compartments with fluid communication being provided between two sub-compartments. One of a two component chemical gas generating system is located in each of the two sub-compartments so that when the pouch is inverted, the chemicals combine to start generating gas to force open the peelable strips.

Apparatus and method for generating pressures for a disposable container

A self-generating gas pressure apparatus such as an expandable closed pouch for placement within a container from which a flowable material therein is to be dispensed under pressure. The apparatus has a plurality of internal compartments formed by pressure-rupturable seals and containing two respective chemical compounds which, when mixed, produce a gas. One of the chemical compounds is in aqueous solution, while the other is a precipitate present in a water-dispersible suspension medium such as a gum, an algin, pectin, or mixtures thereof. The suspension provides for uniform dispersal of the precipitated chemical and a resultant effective reaction rate with the aqueous chemical reactant.
