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.
