Abstract
A self-heating foodstuff container is capable of generating heat by utilizing an exothermic reaction and includes a body having a first chamber for containing a foodstuff and a second chamber for receiving an exothermic reaction agent, and a liquid container including a body portion and a conduit connected to the body portion for discharging the liquid into the second chamber. The body portion is disposed outside of the second chamber and is capable of contracting upon pressure. The container further includes a support member carrying the body portion and slidably mounted with respect to the body in such a manner that the sliding movement of the support member presses the body portion and causes the liquid to discharge through the conduit into the second chamber for initiating the exothermic reaction.
Claims22
A self-heating foodstuff container comprising:
- a body having formed therein a first chamber for containing a foodstuff and a second chamber for receiving an exothermic reaction agent;
- a liquid container including a body portion and a conduit connected to said body portion, said body portion being capable of contracting upon the application thereto of pressure to thereby reduce the volume thereof and being disposed outside of and separated from said second chamber, and said conduit extending into said second chamber and having an open end;
- a support member carrying said body portion of said liquid container and slidably mounted with respect to said body, whereby sliding movement of said support member relative to said body presses and contracts said body portion and causes the liquid to discharge through said conduit into said second chamber for initiating the exothermic reaction;
- and
- said body portion including means for enabling adjustment of the amount of the liquid to be discharged into said second chamber to thereby control the amount of thermal energy to be generated by the exothermic reaction.
A self-heating foodstuff container comprising:
- a body having defined therein a first chamber for containing a foodstuff and a second chamber for receiving an exothermic reaction agent;
- and
- a liquid container including a lower part disposed outside of and separated from said second chamber, an upper part positioned with said second chamber and having an open end for discharging the liquid into said second chamber, and a conduit connecting said lower and upper parts together, said lower part being capable of contracting upon the application thereto of pressure thus reducing the volume thereof and of recovering to a normal volume upon removal of the pressure, said upper part being formed of a material capable of being melted by heat generated by the exothermic reaction, whereby the volume of the liquid supplied for causing the exothermic reaction is adjustable by said lower part to thereby control the amount of thermal energy to be generated.
In a self-heating foodstuff container comprising a body including a first chamber for containing a foodstuff and a second chamber for receiving an exothermic reaction agent and a liquid container for supplying liquid to said exothermic reaction agent to thereby cause an exothermic reaction, said liquid container comprising:
- a body portion having a pleated wall adapted to contract upon the application thereto of pressure thus reducing the volume of said body portion;
- a conduit connected to said body portion and having a funnel-shaped open end;
- and
- a plug fitted in said open end and adapted to be disengaged therefrom by pressure of the liquid when said body portion is contracted, thereby permitting the liquid to discharge from said open end.
