Abstract

A heater device that includes an outer container formed from a vapor impervious material and holds a quantity of heat generating material. A second container is positioned inside the outer container and hold an activation material. A seal on the second container is adapted to be opened to transfer the activation material into contact with the heat generating material to generate heat. The device is useful in heating food such as military field rations.

Claims

exact text as granted — not AI-modified
1 . A heater device, comprising:
 an outer container formed from a vapor impervious material and having a quantity of heat generating material therein;   a second container positioned proximate the outer container and having an activation material therein; and   a seal on the second container adapted to be opened to transfer the activation material into contact with the heat generating material to generate heat.   
   
   
       2 . The device of  claim 1 , wherein the seal includes a strip detatchably mounted on the second container and having an end extending through the outer container, whereby movement of the end opens the seal. 
   
   
       3 . The device of  claim 1 , wherein the seal includes a valve on the second container that is operable to be opened through the outside container. 
   
   
       4 . The device of  claim 1 , wherein the seal includes an activator comprising a sharp element positioned to pierce the wall of the second container. 
   
   
       5 . The device of  claim 1 , wherein the second container includes a rigid side and a flexible side, and the seal is a score cut into the rigid side that is adapted to rupture upon bending to open the second container to allow the activation material to enter the outer container to react with the heat generating material. 
   
   
       6 . The device of  claim 1 , wherein the second container is formed by a wall inside the outer container to thereby divide the outer container into the outer container and the second container. 
   
   
       7 . The device of  claim 6 , wherein the second container further contains sufficient air to break the wall upon application of pressure on the outer container proximate the second container. 
   
   
       8 . The device of  claim 1 , wherein the heat generating material is a mixture of calcium oxide, polyethylene glycol and zeolite. 
   
   
       9 . The device of  claim 8 , wherein the activation agent is water. 
   
   
       10 . The device of  claim 8 , wherein the amount of calcium oxide ranges from about 30 to about 70 weight percent, the amount of polyethylene glycol ranges from about 15 to about 35 weight percent, and the amount of zeolite ranges from about 15 to about 35 weight percent, based on the total weight of heat generating material. 
   
   
       11 . The device of  claim 10 , wherein the amount of water ranges from about 75 to about 125 weight percent, based on the total weight of heat generating material, 
   
   
       12 . The device of  claim 1 , wherein the outer container is sized to cover two sides of a MRE. 
   
   
       13 . The device of  claim 1 , wherein a pair of heater devices are positioned on a MRE, with one of the pair on each side of the MRE. 
   
   
       14 . The device of  claim 13 , wherein the MRE and the pair of heater devices are positioned inside a container. 
   
   
       15 . The device of  claim 1 , wherein the outer container is sized to cover a tray. 
   
   
       16 . A heater device, comprising:
 an outer container formed from a vapor impervious material and having a quantity of heat generating material therein comprising calcium oxide ranges from about 30 to about 70 weight percent, the amount of polyethylene glycol ranges from about 15 to about 35 weight percent, and the amount of zeolite ranges from about 15 to about 35 weight percent, based on the total weight of heat generating material;   a second container positioned proximate the outer container and having an activation material therein comprising water in an amount ranging from about 75 to 125 weight percent, based on the total weight of heat generating material; and   a seal on the second container adapted to be opened to transfer the activation material into contact with the heat generating material to generate heat.   
   
   
       17 . The device of  claim 16 , wherein the outer container is sized to cover two sides of a MRE. 
   
   
       18 . The device of  claim 16 , wherein a pair of heater devices are positioned on a MRE with one of the pair on each side of the container. 
   
   
       19 . The device of  claim 18 , wherein the MRE and the pair of heater devices are positioned inside a container. 
   
   
       20 . The device of  claim 16 , wherein the outer container is sized to cover a tray.
