Abstract

The present invention is directed to a method of assembling a container including an inner tube contained within an outer tube. The method includes providing an outer tube, providing a spacing element adjacent the open top of the outer tube and inserting an inner tube within the outer tube. The spacing element provides for venting of air from between the inner and outer tubes through the top of the container during assembly thereof.

First claim

The invention claimed is:

1. A container assembly kit comprising:
an outer tube having a closed bottom, an open top and a side wall extending therebetween, said side wall defining an inner surface and an outer surface;
an inner tube disposed within the outer tube and having a closed bottom, an open top and a side wall extending therebetween, the side wall of the inner tube being shorter than the side wall of the outer tube and flared outwardly adjacent the open top of the inner tube for sealing and supporting engagement with the side wall of the outer tube;
an annular gap extending between the inner surface of the outer tube and an outer surface of the inner tube in equilibrium with atmospheric pressure at the time of assembly; and
a removable separate spacing element positionable at the open end of the outer tube,
wherein the annular gap is vented to atmospheric pressure during assembly of the container assembly by imparting an interference engagement between the inner tube and the outer tube adjacent the open top of the outer tube, wherein the interference engagement deforms at least one of the inner tube and the outer tube to form a venting gap that is not present after the container assembly has been assembled, wherein the interference engagement between the inner tube and the outer tube is established through the separate spacing element at the open end of the outer tube during assembly, and
wherein at least a portion of the inner surface of the outer tube and an entire upper circumferential surface of the outer surface of the inner tube are sealingly engaged after the container assembly has been assembled.

2. The container assembly kit of claim 1 , wherein the outer container is formed from a polymeric material.

3. The container assembly kit of claim 2 , wherein the outer container comprises polyethylene terephthalate.

4. The container assembly kit of claim 1 , wherein the inner tube is formed from a polymeric material.

5. The container assembly kit of claim 4 , wherein the inner tube comprises polypropylene.

6. The container assembly kit of claim 1 , wherein the spacing element includes at least one extending member extending within the open top of the outer tube during assembly.

7. The container assembly kit of claim 6 , wherein the extending member of the spacing element comprises a material which is at least as hard as a material forming the outer tube.
