Collapsible tube

Claim 2

A collapsible dispensing container comprising a deformable body having low permeability, a thermoplastic headpiece including a peripheral band portion united to an end of said body, and a barrier member of impermeable material fixed to the inner surface of said headpiece and having a peripheral edge disposed within and spaced from the inner wall of said tube end, said headpiece band portion including an annular lip underlying said peripheral edge of said barrier member.

Claim 3

The container of claim 1 wherein said barrier member includes a hollow neck extending centrally through said headpiece for receiving a closure element.

Claim 4

The container of claim 1 wherein said barrier member includes a central apertured portion with valve means for limiting air being drawn into the interior of the container.

Claim 5

A collapsible dispensing container, comprising a deformable body having low permeability, a thermoplastic headpiece, united along a peripheral band portion to an end of said body, and a barrier member of impermeable material fused to the inside surface of said headpiece, said barrier member including spaced rings and ribs projecting from the upper surface of said barrier member, embedded in said headpiece for anchoring the two together.

Claim 6

A collapsible dispensing container, comprising a deformable body having low permeability, a thermoplastic headpiece, united along a peripheral band portion to an end of said body, and a barrier member of impermeable material fused to the inside surface of said headpiece, said barrier member including spaced rings and ribs projecting from the upper surface of said barrier member, embedded in said headpiece for anchoring the two together.

Claim 7

In a collapsible dispensing tube which includes a deformable body having low permeability and a thermoplastic headpiece united along a peripheral band portion to an end of the body, the improvement which comprises a low permeability, barrier member located adjacent to the inside surface of the headpiece; and a plurality of spaced, radial ribs projecting from a surface of the barrier member, embedded in the headpiece, for anchoring the barrier member to the headpiece.

Claim 8

In a collapsible dispensing tube which includes a deformable body having low permeability and a thermoplastic headpiece united along a peripheral band portion to an end of the body, the improvement which comprises a low permeability, barrier member located adjacent to the inside surface of the headpiece; and a plurality of spaced, radial ribs projecting from a surface of the barrier member, embedded in the headpiece, for anchoring the barrier member to the headpiece.

Claim 9

A collapsible dispensing container, comprising: a deformable body having low permeability; a thermoplastic headpiece united along a peripheral band portion to an end of said body; a barrier member of low permeability, secured to the inside surface of said headpiece; a portion of the surface of said barrier member being located adjacent to the inside surface of said headpiece and including a plurality of spaced projections embedded in said headpiece; said plurality of spaced projections, as viewed in a cross-sectional view taken normal to said surface portion of said barrier member, including an inner projection, an outer projection and an intermediate projection separated from said inner and outer projections by a region of said barrier member having a reduced cross section thickness; and said inner projection being more remote from said deformable body than said outer and intermediate projections; and said intermediate projections being located between said inner and outer projections on said surface portion of said barrier member.

Claim 10

A collapsible dispensing container, comprising: a deformable body having low permeability; a thermoplastic headpiece united along a peripheral band portion to an end of said body; a barrier member of low permeability, secured to the inside surface of said headpiece; a portion of the surface of said barrier member being located adjacent to the inside surface of said headpiece and including a plurality of spaced projections embedded in said headpiece; said plurality of spaced projections, as viewed in a cross-sectional view taken normal to said surface portion of said barrier member, including an inner projection, an outer projection and an intermediate projection separated from said inner and outer projections by a region of said barrier member having a reduced cross section thickness; and said inner projection being more remote from said deformable body than said outer and intermediate projections; and said intermediate projections being located between said inner and outer projections on said surface portion of said barrier member.

Claim 11

A container, as defined in claim 6, wherein said spaced projections take the form of annular rings.

Claim 12

A container, as defined in claim 6, wherein said barrier member is made of a material, the melting point of which is substantially higher than the headpiece, and said plurality of projections, embedded in said headpiece, anchor the barrier member to said headpiece.

Claim 13

A container, as defined in claim 8, wherein said spaced projections take the form of annular rings.

Claim 14

A container, as defined in claim 8, wherein said barrier member is a molded member made from a thermosetting material.

Claim 15

A container, as defined in claim 10, wherein said thermosetting material is urea formaldehyde.
