Method and apparatus for making a thermal compress

Abstract

A thermal compress has an outer container defining an inner space. An inner wall provided within the container divides the space into two separate compartments each bounded in part by the outer container in one embodiment of the invention. A control is physically associated with the wall to provide, on the application of manual forces to the container, a passage through the wall at a localized and predictable position. Different substances are respectively located in the above mentioned compartments and separated by the wall until the formation of the passage through the wall whereupon the substances contact each other and perform a thermal reaction to provide heat or cold. With respect to the outer container, two sheets are connected together to form the inner space with a wall being provided in the inner space to divide the same into two compartments with the aforesaid substances being respectively located in these compartments and adapted on contact to effect a thermal reaction. As one form of control, a tear strip is connected between the sheets and to the wall to enable tearing a passage into the wall to permit the substances to mix. Preferably the tear sheet is connected to the wall along a V-shaped seam adapted to form a passage through the wall at a localized and predictable position.
