Abstract
Abstract A parallel tube resin bolting package is disclosed for use in resin bolting operations. The composite package has a generally figure 8 shape in cross-section, with one compartment containing a polyester resin while the other compartment contains a hardener composition. The resin bolting package is particularly useful in applications where the pre-drilled hole has a relatively small diameter.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
119 words
A resin bolting package comprising: two elongated tubular containers formed from a frangible material, and disposed in side by side relation along the longitudinal axes of said elongated tubular containers and joined therebetween such that said package has a configuration which is generally a figure 8 shape in cross-section, with one of said tubular containers being filled with a polyester resin, and with the other said tubular container being filled with a hardener, such that said resin bolting package may be placed in a pre-drilled hole whereby when a bolt is thereafter inserted in said hole, said frangible tubular containers are ruptured with the contents therein mixing and forming a cured two-part plastic producing system for securing the bolt.
Claim 2
Dependent Claim
119 words
A resin bolting package comprising: two elongated tubular containers formed from a frangible material, and disposed in side by side relation along the longitudinal axes of said elongated tubular containers and joined therebetween such that said package has a configuration which is generally a figure 8 shape in cross-section, with one of said tubular containers being filled with a polyester resin, and with the other said tubular container being filled with a hardener, such that said resin bolting package may be placed in a pre-drilled hole whereby when a bolt is thereafter inserted in said hole, said frangible tubular containers are ruptured with the contents therein mixing and forming a cured two-part plastic producing system for securing the bolt.
Claim 3
Dependent Claim
19 words
A resin bolting package as recited in claim 1 wherein said tubular containers are joined together by an adhesive.
Claim 4
Dependent Claim
27 words
A resin bolting package as recited in claim 1 wherein said tubular containers are formed from a thermoplastic material and are joined together by a heat seal.
Claim 5
Dependent Claim
21 words
A resin bolting package as recited in claim 1 wherein said frangible tubular containers are made from a synthetic plastic film.
Claim 6
Dependent Claim
121 words
A resin bolting package comprising: two elongated tubular containers, formed from a frangible synthetic plastic film and disposed in side by side relation along the longitudinal axes of said elongated containers and joined therebetween, such that said resin bolting package has a configuration which is generally figure 8 shaped in cross-section, with one of said tubular containers being filled with a polyester resin, and with the other said tubular container being filled with a hardener, such that said resin bolting package may be placed in a pre-drilled hole whereby when a bolt is thereafter inserted in said hole, said frangible tubular containers are ruptured with the contents therein mixing and forming a cured two-part plastic producing system thereby securing the bolt.
Claim 7
Dependent Claim
121 words
A resin bolting package comprising: two elongated tubular containers, formed from a frangible synthetic plastic film and disposed in side by side relation along the longitudinal axes of said elongated containers and joined therebetween, such that said resin bolting package has a configuration which is generally figure 8 shaped in cross-section, with one of said tubular containers being filled with a polyester resin, and with the other said tubular container being filled with a hardener, such that said resin bolting package may be placed in a pre-drilled hole whereby when a bolt is thereafter inserted in said hole, said frangible tubular containers are ruptured with the contents therein mixing and forming a cured two-part plastic producing system thereby securing the bolt.
Claim 8
Dependent Claim
18 words
A resin bolting package as recited in claim 5 wherein said tubular containers are joined by an adhesive.
Claim 9
Dependent Claim
29 words
A resin bolting package as recited in claim 5 wherein said synthetic plastic film is a thermoplastic material and said tubular containers are joined together by a heat seal.
