Abstract:
A container assembly comprising an outer container formed from a first plastic material and having a closed bottom wall, an open top and a side wall extending therebetween, an inner container formed from a second plastic material and having a closed bottom wall, an open top, a side wall extending from said closed bottom wall of said inner container toward said open top thereof, portions of said inner container adjacent said open top defining an enlarged section having a roughened outer surface defining an array of peaks and valleys, said inner container being disposed within said outer container such that said bottom wall of said inner container abuts said bottom wall of said outer container and such that said roughened outer surface of said inner container adjacent said open top engages said side wall of said outer container, said inner container being spaced inwardly from said side wall of said outer container to define a substantially continuous annular space between said bottom wall and said enlarged section for facilitating insertion of said inner container into said outer container, whereby said roughened outer surface adjacent said open top of said inner container defines circuitous paths for permitting an escape of air from the space between said inner and outer containers.
