Abstract
Abstract A compartmented flexible pouch is provided for filling with at least two liquid materials which are to be stored in isolation from each other. The pouch is made of a thin liquid-impervious flexible film and has front and rear panels joined to each other about all edges except one to leave an opening. Extending from the opening toward the opposite edge there is a linear permanent seal between the inner faces of the two panels extending a first portion of the distance and a linear clamp seal extending the remainder of the distance. The clamp may be removed just prior to use of the composition to permit the two components to blend within the pouch.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
172 words
A compartmented, flexible pouch, suitable for filling with at least two liquid materials which are to be stored in isolation from each other, comprising a front pouch panel and a rear pouch panel, each made of a thin, liquid-impervious, flexible film, said panels facing each other and joined to each other about all edges but one to provide a pouch with an opening a seal between the inner surfaces of said facing panels along a line normal to said opening, extending from said opening toward a closed edge of said panels opposite said opening, dividing said opening into two mouths and terminating at a point spaced from said closed opposite edge and closer to said opening than to said closed opposite edge, a clamp extending from the terminal point of said seal to said closed opposite edge, said clamp being arranged to pinch between its elements both panels of said pouch along a line extending from said terminal point to said closed opposite edge, whereby separate compartments are formed in said pouch.
Claim 2
Dependent Claim
172 words
A compartmented, flexible pouch, suitable for filling with at least two liquid materials which are to be stored in isolation from each other, comprising a front pouch panel and a rear pouch panel, each made of a thin, liquid-impervious, flexible film, said panels facing each other and joined to each other about all edges but one to provide a pouch with an opening a seal between the inner surfaces of said facing panels along a line normal to said opening, extending from said opening toward a closed edge of said panels opposite said opening, dividing said opening into two mouths and terminating at a point spaced from said closed opposite edge and closer to said opening than to said closed opposite edge, a clamp extending from the terminal point of said seal to said closed opposite edge, said clamp being arranged to pinch between its elements both panels of said pouch along a line extending from said terminal point to said closed opposite edge, whereby separate compartments are formed in said pouch.
Claim 3
Dependent Claim
32 words
The compartmented flexible pouch of claim 1 wherein said clamp comprises an elongated C-shaped resilient retention member and a rod dimensioned to fit closely within the hollow of said C-shaped retention member.
Claim 4
Dependent Claim
16 words
The compartmented flexible pouch of claim 1 wherein said liquid-impervious flexible film is a thermoplastic film.
Claim 5
Dependent Claim
26 words
The compartmented flexible pouch of claim 3 wherein said closed edge opposite said opening is a folded edge and wherein said seal is a heat seal.
Claim 6
Dependent Claim
15 words
The compartmented flexible pouch of claim 1 wherein said pouch is of generally rectangular configuration.
Claim 7
Dependent Claim
194 words
A compartmented, flexible pouch, suitable for filling with at least two liquid materials which are to be stored in isolation from each other, comprising a generally rectangular front pouch panel and a generally rectangular rear pouch panel, each made of a thin, liquid-impervious, flexible, thermoplastic film material, said panels facing each other and joined to each other about all edges but one to provide a pouch with an opening, a heat seal between the inner surfaces of said facing panels along a line normal to said opening, extending from said opening toward the edge of said panels opposite said opening, dividing said opening into two mouths and terminating at a point spaced about one-quarter of the distance to said opposite edge, a clamp extending from the terminal point of said seal to said opposite edge, said clamp comprising an elongated C-shaped retention member and a rod dimensioned to fit closely within the hollow of said C-shaped retention member, said rod and retention member being arranged to pinch between them both panels of said pouch along a line extending from said terminal point to said opposite edge whereby separate compartments are formed in said pouch.
Claim 8
Dependent Claim
194 words
A compartmented, flexible pouch, suitable for filling with at least two liquid materials which are to be stored in isolation from each other, comprising a generally rectangular front pouch panel and a generally rectangular rear pouch panel, each made of a thin, liquid-impervious, flexible, thermoplastic film material, said panels facing each other and joined to each other about all edges but one to provide a pouch with an opening, a heat seal between the inner surfaces of said facing panels along a line normal to said opening, extending from said opening toward the edge of said panels opposite said opening, dividing said opening into two mouths and terminating at a point spaced about one-quarter of the distance to said opposite edge, a clamp extending from the terminal point of said seal to said opposite edge, said clamp comprising an elongated C-shaped retention member and a rod dimensioned to fit closely within the hollow of said C-shaped retention member, said rod and retention member being arranged to pinch between them both panels of said pouch along a line extending from said terminal point to said opposite edge whereby separate compartments are formed in said pouch.
Claim 9
Dependent Claim
168 words
A compartmented, flexible package, containing at least two liquid materials stored in isolation from each other, comprising a front pouch panel and a rear pouch panel, each made of a thin, liquid-impervious, flexible film, said panels facing each other and joined to each other about all edges, a seal between the inner surfaces of said facing panels along a line normal to one edge, extending from said edge toward an opposite edge and terminating at a point spaced from said opposite edge and closer to said opening than to said closed opposite edge, a clamp extending from the terminal point of said seal to said opposite edge, said clamp being arranged to pinch between its elements both panels of said pouch along a line extending from said terminal point to said opposite edge, one of said liquid materials being retained in said pouch on one side of said seal and clamp and another of said liquid materials being retained on the other side of said seal and clamp.
Claim 10
Dependent Claim
168 words
A compartmented, flexible package, containing at least two liquid materials stored in isolation from each other, comprising a front pouch panel and a rear pouch panel, each made of a thin, liquid-impervious, flexible film, said panels facing each other and joined to each other about all edges, a seal between the inner surfaces of said facing panels along a line normal to one edge, extending from said edge toward an opposite edge and terminating at a point spaced from said opposite edge and closer to said opening than to said closed opposite edge, a clamp extending from the terminal point of said seal to said opposite edge, said clamp being arranged to pinch between its elements both panels of said pouch along a line extending from said terminal point to said opposite edge, one of said liquid materials being retained in said pouch on one side of said seal and clamp and another of said liquid materials being retained on the other side of said seal and clamp.
