Cosmetics dispenser

An elevator cup configured for vertical sliding movement and for retaining a portion of a solid stick-form product within a dispensing container. The dispensing container has an internal surface, an open top end, a closed bottom end, and means for selectively reciprocally moving the elevator cup in a piston-like manner between a retracted position adjacent the closed bottom end and a fully advanced position adjacent the open top end. The elevator cup includes a horizontal base with top and bottom portions. The top portion is configured for retaining an end portion of the stick-form product. A ductile flange extends along a perimeter of the base for sealing against the internal surface of the container to prevent seepage of liquid product and product volatiles, and to substantially absorb and distribute shock associated with handling of the container, away from the product.

High product retention elevator cup

An applicator for cream-like or gel-like compounds having an elevator in a container that is advanced toward a dome applicator head at one end of the container by turning a helical ramp that engages ramp follows attached to the elevator, the ramp having valleys therein that allow pressure that is present in the compound after a portion has been dispensed through the apertures to force the elevator away from the dome so as to relieve the pressure and prevent the formation of liquid-phase separation products from weeping through the apertures.

Immunoassay test cartridge

A dispenser for liquids includes a dispenser head having an upper section captively mounted upon a lower section over a container of liquid to be dispensed. Removal of a cap from the dispenser head causes the upper section to move upward upon the lower section, for moving a plug out of a fluid flow channel or orifice. When the container is inverted in this open condition, liquid flows out of the container, through the orifice, and wets a rigid porous applicator mounted on top of the dispenser head upper section, for dispensing the liquid. When the cap is replaced on the dispenser head, its upper section is moved downward upon the lower section, causing the plug to enter and seal off the orifice, thereby closing the dispenser.
