Abstract
Abstract A cartridge containing the inter-active components of a resin mix such as a polyester, epoxy or polyurethane, comprises tubular flexible containers, each containing an interactive component, the containers being sealed to prevent egress of their contents, the containers lying in side-by-side relation and preferably secured together by an adhesive such as a double sided adhesive tape.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
The method of making a cartridge containing inter-active components of a self-setting mix comprising the following steps of separately locating a first component of self-setting mix in a first tubular flexible container, separately locating a second component of a self-setting mix in a second tubular flexible container, said containers extending longitudinally, sealing each of said containers at both ends, placing the containers in a side-by-side relationship and securing said containers together to form a cartridge, said first container being filled to assume a generally circular cross-sectional shape and said second container being partially filled and forming said second container to have a generally convex outer surface and a generally concave inner surface in contact with said first container when placed in said side-by-side relationship.
Claim 2
Independent Claim
124 words
The method of making a cartridge containing inter-active components of a self-setting mix comprising the following steps of separately locating a first component of self-setting mix in a first tubular flexible container, separately locating a second component of a self-setting mix in a second tubular flexible container, said containers extending longitudinally, sealing each of said containers at both ends, placing the containers in a side-by-side relationship and securing said containers together to form a cartridge, said first container being filled to assume a generally circular cross-sectional shape and said second container being partially filled and forming said second container to have a generally convex outer surface and a generally concave inner surface in contact with said first container when placed in said side-by-side relationship.
Claim 3
Dependent Claim
17 words
The method of claim 1 including adhesive means interposed between said first container and said second container.
Claim 4
Dependent Claim
13 words
The method of claim 2 wherein said adhesive means is an adhesive tape.
Claim 5
Dependent Claim
15 words
The method of claim 3 wherein said adhesive tape is a double sided adhesive tape.
Claim 6
Dependent Claim
15 words
The method of claim 4 wherein said adhesive tape is a double sided adhesive tape.
Claim 7
Independent Claim
133 words
A method of making a cartridge containing first and second inter-active components of a self-setting mix comprising the steps of providing first and second separate tubular flexible containers, filling said first container with a first component of said self-setting mix so that first container assumes a generally circular cross-sectional shape, partially filling said second container with a second component of said self-setting mix such that such partially filled second container can assume a generally convex outer surface and a generally concave inner surface, said containers extending longitudinally and lying in a side-by-side relationship, forming said second container into a generally and convexo-concave shape by positioning said second container against a circumferential portion of said first container and utilizing adhesive means in contact with said containers to join said containers to form a cartridge.
Claim 8
Independent Claim
133 words
A method of making a cartridge containing first and second inter-active components of a self-setting mix comprising the steps of providing first and second separate tubular flexible containers, filling said first container with a first component of said self-setting mix so that first container assumes a generally circular cross-sectional shape, partially filling said second container with a second component of said self-setting mix such that such partially filled second container can assume a generally convex outer surface and a generally concave inner surface, said containers extending longitudinally and lying in a side-by-side relationship, forming said second container into a generally and convexo-concave shape by positioning said second container against a circumferential portion of said first container and utilizing adhesive means in contact with said containers to join said containers to form a cartridge.
Claim 9
Dependent Claim
13 words
The method of claim 6 wherein said adhesive means is an adhesive tape.
Claim 10
Dependent Claim
19 words
The method of claim 7 wherein said adhesive tape is a double sided adhesive tape interposed between said containers.
