Abstract
Abstract A heat exchange container for use in effecting a temperature change in consumable products is disclosed. Inner and outer containers are connected at one end by a flexible member and define chambers for separating the consumable products from the reaction chamber. The heat exchange occurs through the interaction of a solid chemical mixture and a liquid chemical. The liquid chemical is separated from the solid chemical by an independent container secured within the outer container.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A heat exchange container comprising: an inner container defining a consumable products chamber; an outer container; flexible means connecting said inner and outer containers at one end, said inner and outer containers defining a first chemical chamber surrounding said first contaiNer; and a rupturable container defining a second chemical chamber secured at the other end of said outer container, said rupturable container being a cup-like member having a plurality of crushable ribs extending inwardly from the periphery, a cover extending over the open end of said cup-like member and being sealed to the body portion of said cup-like member wherein said inner container is supported by said ribs whereby pressure exerted on said inner container causes a rupturing of said rupturable container so that chemicals maintained in said first and second chemical chambers become intermixed causing a temperature change to occur.
Claim 2
Dependent Claim
141 words
A heat exchange container comprising: an inner container defining a consumable products chamber; an outer container; flexible means connecting said inner and outer containers at one end, said inner and outer containers defining a first chemical chamber surrounding said first contaiNer; and a rupturable container defining a second chemical chamber secured at the other end of said outer container, said rupturable container being a cup-like member having a plurality of crushable ribs extending inwardly from the periphery, a cover extending over the open end of said cup-like member and being sealed to the body portion of said cup-like member wherein said inner container is supported by said ribs whereby pressure exerted on said inner container causes a rupturing of said rupturable container so that chemicals maintained in said first and second chemical chambers become intermixed causing a temperature change to occur.
Claim 3
Dependent Claim
42 words
A container as set forth in claim 1 further comprising spring means mounted between said inner container and said rupturable container wherein said spring means will urge said inner container upward upon removal of the rupturing force applied to said inner container.
Claim 4
Dependent Claim
151 words
A heat exchange container comprising: an inner container defining a consumable products chamber; an outer container; flexible means connecting said inner and outer containers at one end, said inner and outer containers defining a first chemical chamber surrounding said first container, and a rupturable container defining a second chemical chamber secured at the other end of said outer container, said rupturable container being an inverted cup-like member, a cover sealingly attached to the open end of said cup-like member, a lip projecting outwardly from said inverted cup-like member for receiving said inner container, said inverted cup-like member being formed with an area of reduced cross section extending around said lip wherein pressure exerted on said inner container will cause said inverted cup-like member to fracture along said area of reduced cross section so that chemicals maintained in said first and second chemical chambers become intermixed causing a temperature change to occur.
Claim 5
Dependent Claim
151 words
A heat exchange container comprising: an inner container defining a consumable products chamber; an outer container; flexible means connecting said inner and outer containers at one end, said inner and outer containers defining a first chemical chamber surrounding said first container, and a rupturable container defining a second chemical chamber secured at the other end of said outer container, said rupturable container being an inverted cup-like member, a cover sealingly attached to the open end of said cup-like member, a lip projecting outwardly from said inverted cup-like member for receiving said inner container, said inverted cup-like member being formed with an area of reduced cross section extending around said lip wherein pressure exerted on said inner container will cause said inverted cup-like member to fracture along said area of reduced cross section so that chemicals maintained in said first and second chemical chambers become intermixed causing a temperature change to occur.
Claim 6
Dependent Claim
142 words
A heat exchange container comprising: an inner container defining a consumable products chamber; an outer container; flexible means connecting said inner and outer containers at one end, said inner and outer containers defining a first chemical chamber surrounding said first container; and a rupturable container defining a second chemical chamber secured at the other end of said outer container, said rupturable container being a cup-like member having an annular groove about the periphery of the walls at the open end thereof, a cover sealingly mounted in said annular groove and closing said cup-like member, said cover being formed with an area of reduced cross section for receiving said inner container whereby pressure exerted on said inner container causes a rupture of said cover so that chemicals maintained in said first and second chemical chambers become intermixed causing a temperature change to occur.
Claim 7
Dependent Claim
142 words
A heat exchange container comprising: an inner container defining a consumable products chamber; an outer container; flexible means connecting said inner and outer containers at one end, said inner and outer containers defining a first chemical chamber surrounding said first container; and a rupturable container defining a second chemical chamber secured at the other end of said outer container, said rupturable container being a cup-like member having an annular groove about the periphery of the walls at the open end thereof, a cover sealingly mounted in said annular groove and closing said cup-like member, said cover being formed with an area of reduced cross section for receiving said inner container whereby pressure exerted on said inner container causes a rupture of said cover so that chemicals maintained in said first and second chemical chambers become intermixed causing a temperature change to occur.
