Claim 9:
10. A self-heating container comprising:
an inner cup;
an outer cup, wherein the inner cup is at least partially inside the outer cup to define a space beneath a downward-facing surface of the inner cup and above an upward-facing surface of the outer cup, wherein the space contains:
a granular first substance and a liquid second substance that are adapted to produce an exothermic reaction upon contact with each other,
a soluble container or bag containing and completely surrounding the granular first substance, wherein the soluble container or bag is made entirely of a soluble material that is soluble in the liquid second substance; and
a frangible membrane physically separating the liquid second substance from the soluble container or bag;

a means for rupturing the frangible membrane,
wherein the inner cup is able to rotate about a concentric axis relative to outer cup without moving in an axial direction relative to the outer cup,
the self-heating container further comprising:
a cam or a screw thread configured to cause the means for rupturing the frangible membrane to move in an axial direction toward and through the frangible membrane as the inner cup is rotated about the concentric axis relative to the outer cup; and
a fitment coupled to the means for rupturing the frangible membrane and arranged such that as the means for rupturing the frangible membrane moves in the axially downward direction, the fitment also moves in the axially downward direction pushing the soluble container toward the second substance.
