Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 193 words
A package for reactive multi-component compositions having a multi-layer sandwich-like construction composed of a first heat seal responsive packaging material initially folded lengthwise substantially in V-shape form, a second heat seal responsive material constituting a dividing wall also initially folded lengthwise in substantially V-shape form and disposed in substantially parallel relationship within the opening of the first packaging material; a continuous first seal extending all along the fold line to bond or adhere together the adjacent surfaces at said fold line of the first and second flexible material; a continuous second and third seal extending substantially at right angle to the first seal and axially spaced relative to each other joining at one end said first seal; and a continuous fourth seal extending substantially vertically spaced parallel to said first seal and between and connecting to said second and third seal, all of said seals being of substantially identical construction and located as a margin along the periphery of the package; each of the packaging material surfaces facing each other establishing, except for the seal areas, a non-adhesive relationship to provide three separate and sealed compartments each for containing a dissimilar reacting material.
Claim 2
Dependent Claim 193 words
A package for reactive multi-component compositions having a multi-layer sandwich-like construction composed of a first heat seal responsive packaging material initially folded lengthwise substantially in V-shape form, a second heat seal responsive material constituting a dividing wall also initially folded lengthwise in substantially V-shape form and disposed in substantially parallel relationship within the opening of the first packaging material; a continuous first seal extending all along the fold line to bond or adhere together the adjacent surfaces at said fold line of the first and second flexible material; a continuous second and third seal extending substantially at right angle to the first seal and axially spaced relative to each other joining at one end said first seal; and a continuous fourth seal extending substantially vertically spaced parallel to said first seal and between and connecting to said second and third seal, all of said seals being of substantially identical construction and located as a margin along the periphery of the package; each of the packaging material surfaces facing each other establishing, except for the seal areas, a non-adhesive relationship to provide three separate and sealed compartments each for containing a dissimilar reacting material.
Claim 3
Dependent Claim 40 words
A package according to claim 1, wherein the V-like shaped form of the first and the second material each has a folding edge proximate to the bottom of the V, and each said folding edges are in substantially abutting relationship.
Claim 4
Dependent Claim 21 words
A package according to claim 1, wherein said first and second materials are formed from a continuous web of packaging material.
Claim 5
Dependent Claim 27 words
A package according to claim 1, wherein said package consists of two outer walls formed of said first material and two inner walls of said dividing wall.
