ABSTRACT:
An expandable container comprising two or more slidably engaged sections which are adapted to telescope into a compact unit for storage, but for use the sections are extended to provide two to four times the volume capacity of the closed or unextended container. The fluid and vacuum integrity of the system is obtained by a closure means at each juncture of telescoping sections such as flexible film which is sealed over junctures of the sections, thus leaving the sections free to slide in and out. The expandable container has found particular utility in vacuum liquid collection systems employed by hospitals.
