Abstract: A rotary dispenser with internal pressure relief includes a housing; an elevator slidably and non-rotatably disposed in the housing; a rotatable drive member rotatably disposed in the housing and engaged with the elevator whereby rotation of the drive member slides the elevator relative to the housing; a dome slidably and non-rotatably mounted relative to the housing and having at least one aperture for dispensing product from inside of the housing; and a pressure relief member having a cam and a cam follower, one of the cam and the cam follower being associated with the rotatable drive member and the other of the cam and the cam follower being associated with the dome, the cam follower being rotatably engaged with the cam, whereby rotation of the rotatable drive member relative to the dome rotates one of the cam and the cam follower relative to the other of the cam and the cam follower, the cam having at least one cam surface for causing axial movement of the dome toward the elevator and at least one second

Abstract: A product dispenser including a body housing defining a product cavity for holding a product, a piston movably disposed within the product cavity and a ram assembly aligned with the piston, the ram assembly being adjustable between a storage position for engaging the piston at a storage height and a dispensing position for engaging the piston at a dispensing height, the dispensing height being larger than the storage height.

Abstract: A cosmetic dispenser, includes an applicator having an applicator portion and a cap portion, the cap portion having an inwardly facing screw thread; a container member having a body portion defining a product reservoir and having a neck portion extending from the body portion to receive the applicator, the neck portion having an outwardly facing screw thread for threadedly engaging the inwardly facing screw thread; and a smooth-walled thread guide portion extending from one screw thread of the inwardly facing screw thread and the outwardly facing screw thread toward an opposing screw thread of the inwardly facing screw thread and the outwardly facing screw thread, the thread guide portion being sized to slidingly engage the opposing screw thread so as to guide the opposing screw thread to the one screw thread in proper alignment for threaded engagement.

Abstract: A product dispenser including a product cylinder having a cylinder wall defining a cavity for holding a product, and a housing having a flexible wall defining an inner space for releaseably holding the product cylinder wherein the flexible wall is configurable between a dispensing configuration, wherein the product cylinder is held within the housing, and a refillable configuration, wherein the product cylinder can be removed from the housing.

Abstract: A method and apparatus for applying extrudable product to an application surface while avoiding breakdown of the product into its constituent parts or avoiding undesirable product weeping.

Abstract: A product dispenser includes a housing defining an inner space for a product; a piston member movably disposed in the inner space for dispensing product from the inner space; a ram slidably associated with the housing for driving the piston in the inner space, and movable relative to the housing between an active position wherein the ram is aligned with the piston for dispensing product, and a neutral position wherein the ram is not aligned with the piston whereby the ram in the neutral position is slidable relative to the housing without dispensing product.

Abstract: A dispenser assembly includes an inner housing having an upper end, a lower end, and a wall defining a product space for containing a product to be dispensed; an outer housing having an upper end, a lower end, and a wall defining an inner space, the inner housing being rotatably mounted within the outer housing so that the inner housing can be rotated relative to the outer housing; structure within the housing for advancing product toward the upper end responsive to rotation of the inner housing relative to the outer housing; and a transfer member fixed relative to the outer housing and rotatably associated with the upper end of the inner housing, the transfer member having an applicator surface for applying product to a desired area, and at least one slot in the applicator surface for allowing transfer of product from the product space through the transfer member to the applicator surface.

Abstract: A dispenser-applicator having an elevator for advancing product disposed within a housing having opposed, through sidewall slots. The slots are formed with ratchets and the elevator is actuated by a driver extending through and guided by said slots. The driver is formed with pawls which engage the ratchets so that the elevator can be indexed manually in step by step fashion.

Abstract: A product dispenser includes a housing defining an inner space for a product; a piston movably disposed in the inner space for dispensing product from the inner space; a ram slidably mounted to the housing for driving the piston in the inner space, and rotatable relative to the housing between an active position wherein the ram is aligned with the piston for dispensing product, and a neutral position wherein the ram is not aligned with the piston whereby the ram in the neutral position is slidable relative to the housing without dispensing product.

Abstract: A product dispenser includes a cartridge containing a product; a housing having a base member and a cartridge receiving member movably mounted to the base member between a shipping position wherein the cartridge receiving member is substantially extended from the base member, and a use position wherein the cartridge receiving member is at least partially retracted relative to the base member from the shipping position, the cartridge receiving member having a sidewall defining an interior space for receiving the cartridge; an access defined by the sidewall for installing and removing the cartridge in the interior space; structure associated with the housing for dispensing the product from the cartridge; and structure for resisting dispensing motion of the cartridge receiving member relative to the base member from the shipping position toward the use position.

Abstract: A dispenser for extruding cosmetic gels and cremes including a description of basic sub-assemblies, method of loading the dispenser and method of combining the sub-assemblies.

Abstract: A product dispenser includes a cartridge containing a product; a housing having a sidewall defining an interior space for receiving the cartridge; an access cutout formed in the sidewall for installing and removing the cartridge in the interior space; and a ram and plunger structure associated with the housing for dispensing the product from the cartridge.
