ABSTRACT:
A plural compartment package for housing and storing at least two different materials which are to be mixed together so as to form a compound mixture at the time of use comprises first, second, and third sheets of film material with the third sheet of film interposed between the first and second sheets of film. The three sheets of film material have substantially the same length and width dimensions and are peripherally sealed to each other such that the peripheral seal of the package comprises a three-layer laminate. In addition, the third intermediate sheet of film is secured at a mid-point thereof to one of the first and second sheets of film such that three compartments are formed within the package. The third sheet of film material is provided with easily rupturable perforations so as to facilitate discharge of one material from one compartment into another compartment for mixture with the second material, rupture occurring as a result of pressure applied to the package. A non-porous, rupturable cap overlies the rupturable perforations so as to prevent premature discharge of the first material from the first compartment into the second compartment for mixture with the second material. The pressurizing forces may be concentrated by V-shaped heat-sealed regions, and in addition, an end portion of the package may be torn off so as to define a dispensing spout for the compound mixture.
