Abstract: The invention concerns a plastic cap (1) and a container (4) using same. The plastic cap (1) comprises an oxygen-tight liner (8) to be joined to an opening end surface (6) of a spout (5) on the container (4). The cap (1) has a circumferential skirt (2) with an internal annular bead (3) adapted for snap connection with a corresponding annular groove (7) in the spout (5). The liner (8) has on the side facing the cap (1) a first plastic layer (81), which is arranged to be permanently joined, when injection-molding the cap (1), to the plastic material of the cap (1), and on the side facing the container (4) a second plastic layer (82), which is arranged to be temporarily hermetically sealed to said opening end surface (6).

Abstract: A plastic cap comprises an oxygen-tight liner to be joined to an opening end surface of a spout on a container. The cap has a circumferential skirt with an internal annular bead adapted for snap connection with a corresponding annular groove in the spout. The liner has on the side facing the cap a first plastic layer, which is arranged to be permanently joined, when injection-moulding the cap, to the plastic material of the cap, and on the side facing the container a second plastic layer, which is arranged to be temporarily hermetically sealed to the opening end surface. On the end facing the container, the skirt has a radial projection which serves as a thumb grip and which when opening the container allows the cap to be bent away from the opening end surface so that the temporary, hermetic seal between the second plastic layer of the liner and the opening end surface of the spout is gradually broken.

Abstract: A disposable assembly comprises a drug container (2) having at one end an opening which is surrounded by an outwardly directed flange (7). A connector (1) has a sleeve (13) which is closed (14) at one end and open at its opposite end to receive the flanged end of the drug container as a plunger. Positioning means (18,19) provided within the sleeve and cooperating with the flange define an inserted and a retracted position of said sleeve relative to the flanged end of the drug container. A piercing member (15) provided at the closed end of the sleeve is directed towards the open sleeve end. A connecting member (16) provided at the closed sleeve end is directed opposite to said piercing member (15) and communicating therewith by means of a through passage (17).
