Abstract: The present invention is a mechanically operating device used for packaging and applying a product. A molded product traverses through a barrel as an actuator sleeve is rotated. The actuator sleeve rotates an actuator, propelling a driver through the barrel. The driver is keyed into the barrel using a clutch washer—the clutch washer prevents the rotation of the driver. Mechanical actuating splines on the actuator engage the threads of the driver. The forward motion of the driver transversely pushes a cup out from an orifice of the barrel. The molded product is fitted within the cup. A cap is hermetically sealed to a barrel to create dynamic vapor chamber that prevents any contamination or alteration of the molded product. Primary and secondary seals between the barrel and the cap as well as between the cup and the barrel maintain the airtight feature of the dynamic vapor chamber.

Abstract: A cosmetic tester (10, 110, 210, 310, 410) comprises a base (12, 112, 212, 312, 412) and a cap or matrix (14, 414). The base includes a pedestal (18, 418), a support (20, 120, 220, 320, 420) and an intermediate portion (22, 122, 222, 322, 422) which connects the support to the pedestal. A sample (16, 116, 216, 316, 416) of lip creme or other cosmetic, which is configured as a shell, is secured to the support. The matrix/cap is disposed over the shell and includes a tubular wall (32, 432) which is configured to mate closely with the intermediate portion sufficient for essentially preventing passage of any of the sample between the wall and the intermediate portion, but for permitting escape of air therebetween. The matrix terminates in opposed open (34, 434) and closed (36, 136, 436) ends. The closed end is provided with an inner surface (38, 138, 438) in intimate contact with the sample to provide the it with an external surface whose configuration matches that of the matrix's inner surface.

Abstract: A container (12) includes a discharge outlet (18) and a pliant tubular wall (16) which extends longitudinally from the outlet. The wall of the container is adapted to be deformed by being squeezed for dispensing a mass (24) from the container through the outlet. A piston follower (26, 126) in the container, which is movable towards the outlet and against the mass, has seals (60, 61; 160, 162) that slide on, yet remain sealed with the wall to prevent both leakage of the mass past the seals out of the container and leakage of air past the seals into the container. Degradation in the sealing engagemenet of the seals with the container wall, when the wall is squeezed, even under excessive force, is essentially prevented by a rigid support (72), which is embodied as a ring (138) or radially and longitudinally extending webs (42) acting as struts. The rigid support ensures that the seals will not lose contact with the inner wall surface (17) of container (12).

Abstract: A spring actuated pump device is mounted on a container for fluids, the device including a pump chamber into which fluid from the container can flow, the spring expanding and forcing a cylinder structure against the fluid in the chamber to pressurize it, in order that opening of a discharge valve will effect spraying of a desired quantity of fluid from the device, a suitable nut being threadedly connected to the cylinder structure to enable such structure to be shifted axially, in response to rotation of the nut relative to the container and cylinder structure, to compress the spring and store additional fluid pressure energy therein. A check valve permits ambient air to enter the container to prevent a vacuum condition from developing therein as fluid is withdrawn therefrom. Moreover, fluid is prevented from dribbling from the discharge valve of the device as the spring nears the end of its expansion range.

Abstract: A spring actuated pump device is mounted on a container for fluid, the device including a pump chamber into which fluid from the container can flow, the spring forcing a cylinder structure against the fluid in the chamber to pressurize it, in order that opening of a finger actuated discharge valve will effect spraying of a desired quantity of fluid from the device, a suitable captive nut being swivelly mounted on the container against axial movement with respect thereto, the nut being threadedly connected to the cylinder structure to enable such structure to be shifted axially in response to rotation of the nut relative to the container and cylinder structure to compress the spring and store additional fluid pressurizing energy therein.

Abstract: A device for dispensing fluids employs a manually actuated pump mounted in the neck of a conventional container. The pump includes a stationary piston and a shiftable cylinder which form a pump chamber. The piston includes a check valve which controls the fluid inlet to the pump chamber. The cylinder is spring biased in a direction which pressurizes the fluid in the pump chamber. An upwardly extending neck of the cylinder is exteriorly threaded and carries a discharge valve. A cap which fits over the container neck, cylinder neck and discharge valve has an internally threaded tubular portion which can be engaged with the thread on the cylinder neck. The cap can be turned with the threads engaged to lift the cylinder against the bias of the spring and draw fluid into the pump chamber. With the cap removed, the discharge valve can be opened to allow fluid in the pump chamber to flow through the cylinder neck and exit from the discharge valve.

Abstract: A roll-on dispenser comprises a generally tubular barrel having an open forward end and a generally tubular ball-carrying member having an open rear end which is slidably received in the chamber of the barrel. The ball-carrying member has a ball applicator rollably mounted in its forward end. The rear end of the barrel is vented to the atmosphere, and a one-way follower device is slidably disposed in the barrel chamber for forward sliding movement. A cap is adapted to be threaded on the ball-carrying member and, when screwed thereon, pulls the ball-carrying member forwardly in the barrel chamber to increase the effective volume of the chamber and create a partial vacuum or sub-atmospheric pressure therein, whereupon the atmospheric pressure in the rear end of the barrel chamber will force the one-way follower forwardly by a distance corresponding to the volume of fluent material previously dispensed.

Abstract: A cosmetic applicator, such as a lipstick applicator, includes an inner cosmetic holder or cup in which a cosmetic mass or lipstick is securable, and which is disposed within a carrier sleeve fixed to a base and surrounded by a tubular member having an internal helical groove or thread receiving one or more cup keys extending through longitudinal slots in the sleeve into the helical groove, or meshing with the internal helical thread, so that relative turning between the tubular member and the carrier and base effects advancing and retracting movements of the cup and cosmetic mass along the carrier sleeve. The carrier sleeve has an unslotted forward extension on which an enclosing cap can be mounted which has substantially the same external diameter as the tubular member and base, resulting in an applicator of greater slimness than prior applicators, better appearance and requiring less material.
