ABSTRACT OF THE DISCLOSURE The present invention provides a vessel for storing material in concentrated form, particularly freeze-dried mate- rial which is to be dissolved or diluted by a solvent prior to use, said vessel being adapted to store said material in air- evacuated condition and said vessel comprising: a flexible bag having a closed end and an opening at its opposite end, the opening having peripheral side edges; a rigid cup-shaped cover having walls and an opening towards the atmosphere, the peripheral side edges of the opening in the flexible bag being hermetically connected to the walls of the rigid cover such that the inside of the flexible bag and the inside of the rigid cover define a closed interior space; a connection mem- ber on the outside of the rigid cover forming an integrated part with the rigid cover, the connection member having an opening therethrough and a perforatable, resilient, self-seal- ing membrane extending across the opening, through which mem- brane said interior space is accessible by a puncturing member for adding said solvent to or removing the dissolved or diluted material from said interior space; and a protection member supported by the rigid cup-shaped cover within said interior space at the location of the connection member, for preventing a puncturing member inserted through the connection member from contacting the flexible bag, the protection member having at least one opening therein in communication with said interior space; said concentrated material only taking up a small part of said interior space, which during storage and transport of the vessel is intended to be at least partly evacuated, at which the flexible bag is drawn up against the inside of the rigid cup-shaped cover and totally received therein and protected inside the walls of said cup-shaped cover, and when adding the solvent into said interior volume for dissolving or diluting said concentrated material the flexible bag is allowed to expand in said rigid cover.
