A vessel for safe handling of substances and having a first connection member through which the interior of the vessel is accessible by a device, e.g., an injection syringe, for removing or adding material thereto. At least a part of the vessel is expandable and contractable. The vessel is further provided with a second connection member, which is interconnected or interconnectable with the first connection inside the vessel. The second connection member is connectable to a further vessel outside the vessel, so that substance can be transferred directly from the injection syringe to said further vessel via the first and second connection members.

A vessel and a material stored therein, said material being in concentrated form such as freeze-dried material, said vessel being adapted for storing said material in an at least partly evacuated condition, said vessel being adapted for storage and transport, said vessel being adapted for dissolving or diluting said material by a solvent; said vessel comprising; outer walls defining an inner space for holding said material, at least a part of said outer walls being flexible so that said inner space is expandable and contractible, said concentrated material only taking up a small part of said inner space, said inner space being at least partly evacuated during storage and transport of said vessel; a first connection member on said outer walls through which said inner space is accessible by a first device containing said solvent, said first device being an injection syringe or the like; a second connection member on said outer walls opposite said first connection member, said second connection member being operative for connection thereto of a second device, said second device being a cannula, vein catheter, infusion assembly or the like; said connection members each having an inward portion, said inward portions being interconnectable inside said inner space so as to provide a communication path between said first and second devices when said devices are connected to said first and second connection members and said inner space is contracted; whereby said material can be handled by adding said solvent into said inner space to dissolve or dilute said material and expand said inner space, and then drawing dissolved or diluted material into said first device and contracting said inner space to permit interconnection of said connection members to form said communication path; and wherein said second connection member is provided with a perforatable sealing member; and further including a puncturing member attached to said first connection member for penetrating the sealing member of said second connection member.
