Abstract: The present invention is a positive displacement dispenser which is particularly useful in dispensing viscous materials such as toothpaste. This dispenser has a longitudinally-extending housing which defines a chamber for material to be dispensed, a discharge orifice in the housing through which the material is dispensed from the chamber, a threaded rod having an axis extending through the chamber, a piston with a threaded opening mounted on the rod so that rotation of the rod moves the piston, an actuating lever pivotally mounted to the housing, and a rotatable wheel operatively coupling the threaded rod and the actuating lever so that depression of the actuating lever causes the wheel to turn the threaded rod and advance the piston. The rotatable wheel is coaxially-mounted to the threaded rod and has a plurality of pins mounted on a circular path surrounding the axis of the wheel.

Abstract: A ram gun for dispensing viscous fluid products such as adhesive, caulking materials and the like is disclosed. The gun can be rechargeable or can be employed as a single charge, disposable device. In a particular embodiment, the gun is formed in two parts by molding from plastic material. One part comprises the ram. The other comprises a container section for the material to be dispensed and is provided with integrally formed nozzle, handle and trigger. The trigger has an integrally formed pawl. The trigger is attached to the handle by a thin plastic strip acting as a living hinge and biasing the trigger away from the handle. The ram is slidably mounted in the container section and is incrementally advanced therein by operation of the pawl and rack which is actuated by squeezing of the handle and trigger.

Abstract: Solid or liquid products, such as deodorants are advanced for use and retracted for storage in a dispenser which includes a container, a product supporting cup slidably-mounted within the container, and a delivery mechanism to move the cup upwardly and downwardly within the container. The delivery mechanism which is integrally-formed from plastic with the cup includes a first arm and a second arm each of which have first and second ends connected by an intermediate hinge. The first ends of the first and second arms are connected to the cup with cup hinges. The first and second arms of the delivery mechanism are bent at their intermediate and cup hinges so that the first and second arms form a scissor arrangement with the first ends of the first and second arms crossing and the second ends of the first and second arms crossing. After the arms of the delivery mechanism are positioned in this scissor arrangement, the cup containing a product and the delivery mechanism are inserted into the container.

Abstract: A portable cooler assembly embodying a reversible lid with a handle actuated latch mechanism for latching the lid in either of its two possible positions. The body portion of the cooler is formed with an upstanding flange around the lid so that the top of the lid is substantially flush with the body of the cooler regardless of how it is placed on the cooler body. The handle is nested between this upstanding flange and the lid when the handle is in a storage position so as to provide an uncluttered appearance and to protect the handle from accidental damage.

Abstract: Disclosed is a package for dispensing flowable materials such as powders and liquids, particularly those intended for cosmetic use. A cover (30) fits snugly against chamber wall (12) and overlies dispensing opening (14). Removal of the cover draws a measured quantity of flowable product (50) through conduit (40) and out of the dispensing opening. A vent opening (22) through the chamber wall is preferably provided to permit the interior of the chamber to adjust to atmospheric pressure. And, a cover relief opening (32) is preferably provided to permit easy replacement of the cover and control of the quantity of product dispensed.

Abstract: An improved insulated tray having both of its top and bottom surfaces configured so that either may receive food articles. In addition, the configuration is such that the trays may be stacked one upon the other in a wide variety of configurations. When so stacked, the depressions in the upper tray serve to provide a closure for the depressions in the lower tray.

Abstract: A safety goggle including a one-piece wrap-around front with hinged temples continuing rearwardly therefrom. The goggle features improved anti-fogging ventilation and universal nasal area face fitting.

Abstract: A battery-powered apparatus, for inducing air flow past a product capable of being vaporized, includes a compact housing that comprises a hollow outer shell and a hollow, generally cylindrical inner shell, having an axis, on which the operating components of the apparatus are supported. The inner shell is mounted with the outer shell by a hinge to pivot substantially on the axis between closed and open positions. In the closed position the inner shell compliments the outer shell to define an enclosed space and shield the apparatus components. In the open position, the inner shell is nested within the outer shell to expose the apparatus components. The product and a battery for powering the apparatus may be assembled into a cartridge formed to be received in the apparatus housing. Electrical battery contacts and a support for the cartridge in the housing are also disclosed.
