Abstract
A vessel for receiving fluid includes a flexible part having a closed end and an opening at its opposite end, and a rigid protective cover, the edges of the opening in the flexible part being attached to the rigid cover in a manner such that the inside of the flexible part and the inside of the cover define a closed interior space, the flexible part being capable of being drawn up against the inside of the protective cover upon evacuation of the interior space whereby the flexible part is received within the protective cover. A connection member is provided on the outside of the protective cover, the connection member having a bore therethrough and a perforatable, resilient, self-sealing membrane extending across the bore, through which membrane a puncturing member may be inserted for removing material from or adding material to the interior space. A protection member is supported by the protective cover within the interior space at the location of the connection member for preventing a puncturing member inserted through the connection member from contacting the flexible part, the protection member having at least one opening therein in communication with the interior space.
