Abstract: A dispenser assembly for dispensing a substance from a receptacle is provided. Preferably the collar therefore comprises outwardly projecting and elongated angled ribs for forming complementary elongated grooves in the outer surface of the ferrule. A method of assembling such a dispenser assembly upon a receptacle is also provided and comprises the important step of allowing the collar to rotate over the outer surface of the ferrule and towards the receptacle, such that the elongated ribs form complementary elongated grooves in the outer surface of the ferrule thereby forming an airtight seal between the dispensing assembly and the receptacle.

Abstract: A cosmetic preparation dispenser is provided that has a resilient tab formed on the lower end of the innerbody that presses against the cam sleeve to provide a desirable swivel drag, and which tab is prevented from undesirable deformation that reduces the swivel torque by providing a relaxation zone in the cam sleeve where the tab can recall its original shape. The relaxation zone is preferably a thin walled section of the cam sleeve that is formed by the combination of a flat outer wall and a circular inner wall, which thin walled section is deformable by pressure from the tab when the tab is seated against the thin walled section. The tab presses against the cam sleeve which causes the cam sleeve to move up a bevelled shoulder to enhance swivel drag between the cam sleeve and a retaining lip on the innerbody. The bevelled shoulder also engages the cam sleeve when force is applied to the elevator.

Abstract: A cosmetic preparation dispenser is provided that has an incremental feel created by the interaction of a resilient tab extending outwardly from the dispenser's innerbody with a plurality of rib elements provided on a surrounding wall of a cam sleeve so that the tab cams up and down on the ribs to increase and decrease resistance to relative rotation of innerbody and cam sleeve to give the desired incremental feel.

Abstract: A lipstick dispenser having a propel/retract mechanism that permits shaped pomades and shaped outer casings, without requiring excessive length to accommodate the mechanism, comprises a base, a helical spring affixed to and extending from the base, a sleeve fitted over the helical spring and having an engaged end which is rotably affixed to the base, and an elevator cup fitted into the sleeve and having an extending stem with a threaded portion for engaging with the helical spring. Relative rotation of the spring and the threaded portion caused by rotation of the base and sleeve causes axial movement of the elevator cup. During retraction of the elevator cup, the spring accumulates and is compressed in the zone of the stem between the cup and the threaded portion of the elevator cup.

Abstract: A water-closet installation is disclosed, which comprises two pans (2, 2'; 20, 20') inside a housing (10) which pans are fixed to a rotary shaft (W; 27), and which, by rotation of the shaft around 180.degree. are movable into each others position. Hereby the upper pan is lowered after utilization and primary rinsing to be fine-washed, disinfected and dried.
