Abstract: The invention relates to disposable devices for introducing substances into body cavities of a patient. The device comprises a container for holding a substance which is connected to a tube ending in an opening which is inserted into a body cavity. The opening is sealed by a frangible seal located inside the opening. An actuating rod ruptures and removes the seal upon actuation. The actuating rod is provided with supporting rods extending to the container which are connected to the container by frangible connections. The supporting rod serves as a safe-guard against accidental rupture of the seal and as a guide for a controlled movement of said the actuating rod. The supporting rod also defines and protects an area to be kept sterile. The invention also relates to a moulding apparatus and to a method for making said device.

Abstract: A sealing device for bag-shaped, liquid containers for sick-care of flexible material. An opening for filling or emptying the container is sealed by means of a disc-shaped member which has a tube made in one piece therewith and extending in use towards the interior of the container. One end of the tube adjacent the disc-shaped member being closed by a cover which seals against the outside surface of the disc-shaped member level therewith, and the other end of the tube is sealed by means of a flattening of the tube, to produce a sterile space between the two closed ends of the tube, said flattened portion of the tube extending transversely to the longitudinal direction of the tube to form two tube sidewall portions converging towards the flattened portion of the tube, at least one of said sidewall portions being penetrable by a cannula when inserted through the mouth of the tube and extending through the tube.

Abstract: The neck opening of a filled plastic bottle is sealed by a sealing unit ultrasonically welded to the top of the neck. The sealing unit can be a one-piece member having an upwardly projecting hollow portion arranged to be broken off to provide an opening for dispensing the contents of the bottle. Alternatively, the sealing unit can be composed of an inner cap, an outer cap and a sealing disc interposed between the caps, this unit being arranged to be pierced by a cannula for withdrawing the contents of the bottle.
