Abstract
Abstract A safety package assembly for isolating chemically reactive constituents until ready for intermixing comprising inner and outer tubular containers, the opposite ends of the inner container being charged with proper quantities of the two reactive constituents and previously held isolated by a detachable divider clamp assembly applied crosswise of the collapsed midportions of said container. A wall failure at either or both ends of the inner container merely permits a constituent to escape into the contiguous compartment of the outer container. Even when both ends of the inner compartment fail the constituents are retained captive and positively isolated until removal of the clamp. The divider clamp assembly is formed of differentially resilient materials, the stiffer more resilient outer member having sharp edged ribs positioned to press the container walls against the softer inner clamping member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
167 words
A safety package assembly for retaining chemically reactive constituents isolated until ready for intermixing comprising elongated inner and outer non-compartmented tubular containers of impervious thermoplastic sheet material, said inner container being generally as long as but smaller than and enclosed within said outer container and the opposite ends of both containers being sealed closed, a divider assembly detachably embracing said containers crosswise of their compactly flattened midportions effective to divide each container into separate fluid-tight compartments at the opposite ends thereof, said separate compartments of said inner container being charged one with one constituent and one with a different constituent reactive with one another upon removal of said divider assembly, the separate compartments of said outer container outwardly of said inner container being normally free of either of said constituents, and said divider assembly being effective to maintain said chemically reactive constituents isolated from one another within the respective contiguous ends of said inner and outer containers despite a failure in the wall of said inner container.
Claim 2
Dependent Claim
167 words
A safety package assembly for retaining chemically reactive constituents isolated until ready for intermixing comprising elongated inner and outer non-compartmented tubular containers of impervious thermoplastic sheet material, said inner container being generally as long as but smaller than and enclosed within said outer container and the opposite ends of both containers being sealed closed, a divider assembly detachably embracing said containers crosswise of their compactly flattened midportions effective to divide each container into separate fluid-tight compartments at the opposite ends thereof, said separate compartments of said inner container being charged one with one constituent and one with a different constituent reactive with one another upon removal of said divider assembly, the separate compartments of said outer container outwardly of said inner container being normally free of either of said constituents, and said divider assembly being effective to maintain said chemically reactive constituents isolated from one another within the respective contiguous ends of said inner and outer containers despite a failure in the wall of said inner container.
Claim 3
Dependent Claim
21 words
A safety package assembly as defined in claim 1 characterized in that said inner container is separate from said outer container.
Claim 4
Dependent Claim
28 words
A safety package assembly as defined in claim 1 characterized in that said inner and outer containers are sealed closed at their opposite ends independently of one another.
Claim 5
Dependent Claim
41 words
A safety package assembly as defined in claim 1 characterized in that said inner container is enclosed within said outer container with its walls and opposite ends in close proximity to but disconnected from the juxtaposed walls of said outer container.
Claim 6
Dependent Claim
138 words
A safety package assembly as defined in claim 1 characterized in that said divider assembly comprises a pair of internesting differentially resilient first and second members each having a length greater than the flattened width of said containers, said first member being relatively soft and said second member being relatively stiff and U-shaped in cross section with the inner surface shaped to embrace and press said first member and the flattened sides of said inner and outer containers snugly opposite a major portion of the girth and length of said first member, and the inner surface of said second member being formed with a plurality of sharp edged nonresilient ribs extending lengthwise thereof in position to compress the juxtaposed walls of said containers forcibly against one another and against the underlying relatively soft surface of said first member.
Claim 7
Dependent Claim
27 words
A safety package assembly as defined in claim 5 characterized in that said sharp edged ribs are integral with a respective leg of said U-shaped second member.
Claim 8
Dependent Claim
32 words
A safety package assembly as defined in claim 5 characterized in that said U-shaped member is formed of nonmetallic elastomeric material having a durometer of approximately Rockwell 78 on the D Scale.
Claim 9
Dependent Claim
42 words
A safety package assembly as defined in claim 5 characterized in that said first member is tubular and having a cross-sectional shape generally conforming to the juxtoposed interior contour of that portion of said second member free of said sharp edged ribs.
Claim 10
Dependent Claim
28 words
A safety package as defined in claim 1 characterized in that the wall strength of said outer container is greater than the wall strength of said inner container.
Claim 11
Dependent Claim
57 words
A safety package as defined in claim 1 characterized in that said inner and outer containers are sealed closed independently of one another whereby a sealing failure at either end of said inner container merely releases the contents of the adjacent end half of said inner container into the associated surrounding end half of said outer container.
