Abstract

A self-heating container assembly has a housing with a first portion and a second portion, each having a cylindrical cross-section. The first portion and the second portion are mated together in a manner that permits the first portion to rotate about a common axis relative to the second portion. A ring gear (or partial ring gear) is on or attached to the first portion and rotates with the first portion of the housing relative to the second portion. A rotatable cutting element is supported by a support connected to the second portion of the housing. There is a pinion gear on the rotatable cutting element. The pinion gear is coupled to the ring gear. A reactant container containing a reactant is adjacent to the rotatable cutting element, such that rotation thereof cuts into the reactant container.

Dependent claims

A self-heating container assembly comprising:

a housing comprising:
a first portion having a cylindrical cross-section;
and
a second portion having a cylindrical cross-section,
wherein the first portion of the housing and the second portion of the housing are mated together in a manner that permits the first portion to rotate about a common axis relative to the second portion;
a ring gear on or attached to the first portion of the housing and configured to rotate with the first portion of the housing relative to the second portion of the housing;
a rotatable cutting element supported by a support connected to the second portion of the housing;
a pinion gear on the rotatable cutting element and coupled to the ring gear;
and
at least one reactant container containing a reactant adjacent to the rotatable cutting element, such that rotation of the rotatable cutting element results in the rotatable cutting element cutting into the at least one reactant container.
