Laminated materials container

Claim 2

A container in combination with a compound having organic solvent components, said container for storage and use of said compound, comprising: a tubular housing having a hollow interior amd a surrounding side wall for holding a material having an organic solvent component, said side wall formed out of an inner lining of first high barrier transparent plastic material facing said interior to contact material placed therein and an outer sleeve of a second transparent plastic material different from said first high barrier transparent plastic material such that said side wall is transparent around its circumference; first closure means on a first end of said tubular housing for enclosing said first end said first closure means including an end wall having a dispensing nozzle in fluid communication with said hollow interior; second closure means in spaced relation to said first closure means for enclosing a second end of said tubular housing said second closure means including a movable wall slideably received in said tubular housing whereby forced movement of the movable wall toward said end wall will expel the contained material from said nozzle, and said outer sleeve fabricated of a material selected from transparent and rigid plastic materials and selected to approximately match the index of refraction of said compound to be held by the container.

Claim 3

A container for holding materials having organic solvent components for storage and use, comprising: a tubular housing having a hollow interior and a surrounding side wall for holding a material having an organic solvent component, said side wall formed out of an inner lining of first high barrier transparent plastic material facing said interior to contact material placed therein and an outer sleeve of a second transparent plastic material different from said first high barrier transparent plastic material such that said side wall is transparent around its circumferences: first closure means on a first end of said tubular housing for enclosing said first end said first closure means including an end wall having a dispensing nozzle in fluid communication with said hollow interior: second closure means in spaced relation to said first closure means for enclosing a second end of said tubular housing said second closure means including a movable wall slideably received in said tubular housing whereby forced movement of the movable wall toward said end wall will expel the contained material from said nozzle, and one of said outer sleeve and said inner lining has a plurality of longitudinal 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 longitudinal ribs dimensioned to be received in said micro-channels to increase the contact surface area between the inner lining and outer sleeve thereby frictionally locking the outer sleeve and inner lining together to prevent longitudinal movement of one relative to the other.

Claim 4

A container for holding materials having organic solvent components for storage and use, comprising: a tubular housing having a hollow interior and a surrounding side wall for holding a material having an organic solvent component, said side wall formed out of an inner lining of first high barrier transparent plastic material facing said interior to contact material placed therein and an outer sleeve of a second transparent plastic material different from said first high barrier transparent plastic material such that said side wall is transparent around its circumferences: first closure means on a first end of said tubular housing for enclosing said first end said first closure means including an end wall having a dispensing nozzle in fluid communication with said hollow interior: second closure means in spaced relation to said first closure means for enclosing a second end of said tubular housing said second closure means including a movable wall slideably received in said tubular housing whereby forced movement of the movable wall toward said end wall will expel the contained material from said nozzle, and one of said outer sleeve and said inner lining has a plurality of longitudinal 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 longitudinal ribs dimensioned to be received in said micro-channels to increase the contact surface area between the inner lining and outer sleeve thereby frictionally locking the outer sleeve and inner lining together to prevent longitudinal movement of one relative to the other.

Claim 5

A container for holding materials having organic solvent components for storage and use, comprising: a tubular housing having a hollow interior and a surrounding side wall for holding a material having an organic solvent component, said side wall formed out of an inner lining of first high barrier transparent plastic material facing said interior to contact material placed therein and an outer sleeve of a second transparent plastic material different from said first high barrier transparent plastic material such that said side wall is transparent around its circumference: firt closure means on a first end of said tubular housing for enclosing said first end, said first closure means including an end wall having a dispensing nozzle in fluid communication with said hollow interior: second closure means in spaced relation to said first closure means for enclosing a second end of said tubular housing said second closure means including a movable wall slideably received in said tubular housing whereby forced movement of the movable wall toward said end wall will expel the contained material from said nozzle, and said outer sleeve and said inner lining each include mating corrugations longitudinally extending along their respective facing surfaces and positioned circumferentially therearound to provide increased surface contact are between the inner lining and outer sleeve to frictionally lock the outer sleeve and inner lining together to prevent their longitudinal movement relative to one another.

Claim 6

A container for holding materials having organic solvent components for storage and use, comprising: a tubular housing having a hollow interior and a surrounding side wall for holding a material having an organic solvent component, said side wall formed out of an inner lining of first high barrier transparent plastic material facing said interior to contact material placed therein and an outer sleeve of a second transparent plastic material different from said first high barrier transparent plastic material such that said side wall is transparent around its circumference: firt closure means on a first end of said tubular housing for enclosing said first end, said first closure means including an end wall having a dispensing nozzle in fluid communication with said hollow interior: second closure means in spaced relation to said first closure means for enclosing a second end of said tubular housing said second closure means including a movable wall slideably received in said tubular housing whereby forced movement of the movable wall toward said end wall will expel the contained material from said nozzle, and said outer sleeve and said inner lining each include mating corrugations longitudinally extending along their respective facing surfaces and positioned circumferentially therearound to provide increased surface contact are between the inner lining and outer sleeve to frictionally lock the outer sleeve and inner lining together to prevent their longitudinal movement relative to one another.

Claim 7

A container according to claim 3 wherein said inner lining is fabricated of amorphous nylon.

Claim 8

A container according to claim 3 wherein the outer sleeve is fabricated of polyethylene teraphthalate.

Claim 9

A container according to claim 3 wherein said ratio of the thickness of the inner lining to the thickness of the outer sleeve is approximately 1:x where 2.5 <X<5.0.
