Container assembly for warming beverages and method of forming and using it

A method of manufacturing a container assembly for warming beverages, comprising the steps of:

• (a) forming from a mold a generally cylindrical plastic container having an open top, a flexible closed bottom and a lower compartment extending upward from the bottom, said lower compartment including a lower compartment outer wall and including an annular central divider perpendicular to the closed bottom, the annular divider having an sufficiently sharp upper edge for piercing a partition,
• (b) placing a salt compound in the lower compartment in a first amount so that the salt compound is as high or higher than the annular divider, and so that the salt compound is placed in the lower compartment between the annular central divider and the lower compartment outer wall,
• (c) covering an inside of the lower compartment with a pierceable partition that divides a water compartment from the salt compound so that the annular divider is lower than the partition,
• (d) pouring an amount of water into the water compartment, said first amount of salt compound and said amount of water defined in proportion to each other and defined sufficient to heat the quantity of the particular beverage to a specified temperature that is ideal for consumption when the salt compound mixes with the water,
• (e) affixing a generally U-shaped cup capable of holding in an interior of the cup a particular beverage in need of being warmed, the cup having an upper portion that fits snugly with an upper perimeter of the container, said cup made of a heat transmitting material, and said cup being sufficiently rigid to withstand penetration of salt water into the interior of the cup, the cup being in sufficient contact with the water so as to absorb heat from the water at least when the container assembly is turned upside down,
• (f) placing a particular beverage that needs to be warmed in the interior of the cup,
• (g) placing a cover on the cup, the container assembly allowing a user to manually pressure the bottom of the container to deform said bottom thereby causing the annular divider to pierce the partition and upon shaking the container assembly causing the salt compound to dissolve in the water thereby generating an exothermic reaction that warms the particular beverage to a specified temperature that is ideal for consumption.

A container assembly for warming beverages, comprising:

• a generally rectangular container with substantially rounded corners,
• a flexible closed bottom,
• a lower compartment extending from the bottom upward,
• a water compartment including a first amount of water, said water having a water surface,
• a generally U-shaped cup that holds a substantially full quantity of a particular beverage that needs to be warmed in an interior of the cup, the cup having a cover, and the cup having an upper portion that fits snugly with an upper perimeter of the container and a remaining lower portion that is narrower than the container, said cup made of a heat transmitting material, and said cup being sufficiently rigid to withstand penetration of salt water into the interior of the cup, the cup being in sufficient contact with the water so as to absorb heat from the water at least when the container assembly is turned upside down,
• the lower compartment being bounded above by a pierceable partition made of foil material,
• an annular central divider perpendicular to the bottom and having a sufficiently sharp upper edge for piercing the partition when a manual pressure is applied upwardly to a central portion of the flexible bottom sufficient to deform the bottom,
• a salt compound stored in the lower compartment between the anular central divider and a lower compartment outer wall, in a second amount defined in proportion to the first amount of water and sufficient to heat the quantity of the particular beverage to a specified temperature that is ideal for consumption when the salt mixes with the water after the partition of foil material is pierced and the container assembly is turned upside down and shaken, wherein the salt compound fills the lower compartment to a top of the lower compartment.
