ABSTRACT:
The present invention is a package for housing and mixing two materials, such as epoxy resin and polyamine adduct, together to form an adhesive. Two sheets are joined together to form the outer periphery of the bag. A third sheet is secured between the outer sheets and divides the package into two compartments. One compartment includes a line of perforation holes that are easily ruptured when a user applies pressure to the external area of the compartment. A cap covers the perforation holes so that the material contained within the rupturable bag will not leak into the other compartment. When the one compartment is ruptured, the adduct that is contained therein is released into the other compartment and mixes with the resin. After the two materials are completely mixed the adhesive is ready for use.
