Patent abstract
A tube assembly includes an inner tube telescoped into an outer tube. The inner tube is dimensioned to define a substantially annular space between the inner and outer tubes. Portions of the inner tube near its open top are configured to permit venting as the inner tube is inserted into the open top. However, the vent is closed during insertion of a closure into the tube assembly or prior to inserting a closure into the tube assembly.
