Abstract
Abstract A canister for an explosive primer containing capsensitive aqueous gel explosive is formed from a thermoplastic by blow-molding a pair of semi-cylindrical bottles connected by an integral hinge which have one or more corresponding grooves in their mating flat longitudinal surfaces. When the flat surfaces of the two containers are placed in contact and the containers are fastened together to form a cylinder, the matching grooves form a central longitudinal tubular passage through the canister and, if desired, one or more cylindrical wells in close proximity to the central passage.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
83 words
A canister for an aqueous gel explosive primer which comprises a pair of semi-cylindrical plastic bottles joined by an integral hinge along one longitudinal edge of each bottle, said bottles having corresponding grooves in their mating flat longitudinal surfaces so that when the flat surfaces are brought together to form a cylindrical structure the corresponding grooves come together to form a central longitudinal tubular passage through the canister and one or more cylindrical cavities in close proximity to said central longitudinal tubular passage.
Claim 2
Dependent Claim
83 words
A canister for an aqueous gel explosive primer which comprises a pair of semi-cylindrical plastic bottles joined by an integral hinge along one longitudinal edge of each bottle, said bottles having corresponding grooves in their mating flat longitudinal surfaces so that when the flat surfaces are brought together to form a cylindrical structure the corresponding grooves come together to form a central longitudinal tubular passage through the canister and one or more cylindrical cavities in close proximity to said central longitudinal tubular passage.
Claim 3
Dependent Claim
32 words
A canister according to claim 1 in which there is a connecting conduit between the pair of semi-cylindrical bottles when the flat longitudinal surfaces are brought together to form a cylindrical structure.
Claim 4
Dependent Claim
17 words
A canister according to claims 1 or 2 which is filled with a cap-sensitive aqueous gel explosive.
