Container assembly and method for making assembly

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.
