Abstract
Abstract A container for viscous materials having volatile components is constructed to have substantial transparency. The container includes a tubular housing having first and second closing structures at opposite ends. The housing may be entirely constructed of amorphous nylon, but preferably is formed as a laminate having a relatively thin inner lining of high barrier amorphous nylon and an outer sleeve of low barrier plastic, such as plyethylene terephthalate. In one embodiment the container is adapted for caulking compounds wherein the first closing structure is an end wall, nozzle and snout assembly and wherein the second closing structure is defined by a moveable piston slideably received in the housing interior. The transparent side wall of the housing and the snout are indexed whereby the snout is severed at a desired location, which determines the outlet size, and the side wall indexing is correlated to outlet size to inform the user of the length of the caulking bead that may be obtained from the contents remaining in the housing as shown by the position of the piston relative to the side wall indexing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
227 words
A product for use in the building industry, comprising a cartridge formed as an elongated tubular housing having a longitudinal axis and surrounding sidewall fabricated of a transparent material, said housing having a hollow interior, a nozzle member enclosing a downstream end of said cartridge, a substantially transparent caulking compound contained in said cartridge, said caulking compound adapted to be placed on a substrate, and a piston member slideably received in the interior of said cartridge and enclosing an upstream end thereof so that the piston member may be pressed against the caulking compound to force the caulking compound out of said nozzle member as said piston member is moved downstream through said housing to dispense said caulking material onto said substrate whereby the combination of said housing and said caulking compound is substantially transparent in the transverse direction so as to allow a user to see completely through the surrounding sidewall and through the caulking compound from one side of the cartridge to the other whereby the substrate may be viewed through the combination of the housing and the caulking material placed therein so that the apperance of the substrate as affected by the caulking material may be seen prior to application of the caulking material and whereby the position of the piston member may be viewed as the caulking material is dispensed from the housing.
Claim 2
Dependent Claim
227 words
A product for use in the building industry, comprising a cartridge formed as an elongated tubular housing having a longitudinal axis and surrounding sidewall fabricated of a transparent material, said housing having a hollow interior, a nozzle member enclosing a downstream end of said cartridge, a substantially transparent caulking compound contained in said cartridge, said caulking compound adapted to be placed on a substrate, and a piston member slideably received in the interior of said cartridge and enclosing an upstream end thereof so that the piston member may be pressed against the caulking compound to force the caulking compound out of said nozzle member as said piston member is moved downstream through said housing to dispense said caulking material onto said substrate whereby the combination of said housing and said caulking compound is substantially transparent in the transverse direction so as to allow a user to see completely through the surrounding sidewall and through the caulking compound from one side of the cartridge to the other whereby the substrate may be viewed through the combination of the housing and the caulking material placed therein so that the apperance of the substrate as affected by the caulking material may be seen prior to application of the caulking material and whereby the position of the piston member may be viewed as the caulking material is dispensed from the housing.
Claim 3
Dependent Claim
15 words
A product according to claim 1 wherein said caulking compound is a block copolymer rubber.
Claim 4
Dependent Claim
15 words
A product according to claim 1 wherein said side wall is fabricated of amorphous nylon.
Claim 5
Dependent Claim
42 words
A product according to claim 1 wherein said side wall includes an outer sleeve and an inner lining, said outer sleeve fabricated of a transparent plastic having an index of refraction of approximately 1.45 and said inner lining fabricated of amorphous nylon.
Claim 6
Dependent Claim
21 words
A product according to claim 4 wherein said outer sleeve and said inner lining are bonded together by a transparent adhesive.
Claim 7
Dependent Claim
25 words
A product according to claim 4 wherein said outer sleeve and said inner lining each include mating corrugations longitudinally extending along their respective facing surfaces.
Claim 8
Dependent Claim
84 words
A produce according to claim 4 wherein one of said outer sleeve and said inner lining has a plurality of micro-channels having channel openings facing the other one of said outer sleeve and said inner lining, said channel openings having a smaller circumferential dimension than the circumferential width of the micro-channels, the other one of said outer sleeve and said inner lining having a plurality of ribs dimensioned to be received in said micro-channels to mechanically lock the outer sleeve and inner lining together.
Claim 9
Dependent Claim
93 words
A product according to claim 1 including first index markings on said side wall whereby the position of the piston member indicates the amount of viscous material remaining in the tubular housing and second index markings on said snout for indicating the size of the outlet when the snout is severed at a selected second index marking, said first and second index markings correlated whereby, for a selected second index marking, the first index markings determine the linear length of the bead which may be applied by the remaining volume of viscous material.
