Abstract: A valve, which is especially suited for use in connection with a urine bag, has a cylindrical valve body, which is displaceably and rotatably mounted in a tubular valve housing having a transverse flow passage defined therein. A projection formed at one end of the valve body may be brought into engagement with a cut-out or notch in the adjacent end of the valve housing. In this position in which the projection engages with the notch, the valve is open, because the transverse bore of the valve body is aligned with the flow passage. The valve may be closed by displacing the valve body in relation to the valve housing so as to bring the projection out of engagement with the notch, and the valve body may be rotated in relation to the valve housing, if desired. The engagement between the projection and the notch ensures that the transverse bore of the valve body extends coaxially with the flow passage in the open position of the valve.

Abstract: An ejection piston for use in cylindrical dispensing containers or packages of the type containing viscous or plastic masses such as sealing compounds and adhesives. The piston assembly comprises a piston part having a peripheral skirt as well as an arched piston top, and a separate piston actuating member arched in a direction opposite to the piston top. An ejection pressure is applied to the actuating member and transmitted to the piston top whereby the effective diameter of the piston top is slightly increased. An annular sealing sleeve for receiving the piston skirt and the adjacent free end of the cylindrical container during storage may be formed integrally with the piston actuating member.

Abstract: A closure, preferably for pharmaceutical containers or bottles, and composed by a metal cap member with a central opening and a depending skirt, and a cover member closing the central opening of the cap member and sealingly engaging with the inner rim portion thereof. According to the invention the inner rim portion of the cap member is inclined inwardly at an acute angle, and when the cover member is later removed the rim portion is deformed or bent outwardly. The inner rim portion of the cap member is preferably bent to its inclined position when the cover member is mounted in the central opening of the cap member.
