Abstract: A screw-operated dispenser providing for prevention of breakage of an engaged screw when a user rotates a turn member in the wrong direction, i.e., repels rather than propels an elevator. A tubular body holds a supply of product, which is dispensed by action of the elevator along a threaded shaft upon turning a base to either propel or repel the elevator along the shaft which is threadably engaged with the elevator. Certain lowermost revolutions of the thread on the shaft are chamfered at the bottom edge thereof so that when the elevator is in a lowermost position on the screw shaft and a user mistakenly rotates the turn member in a repel direction, the thread of the elevator will not engage, i.e., will override, the thread of the screw shaft thereby eliminating stress and/or pressure between the threads which may result in breakage of the screw shaft and render the dispenser inoperable.

Abstract: A propel/repel dispenser having one or more features in combination to provide improved manufacture, assembly and use of the dispenser. Such features include a wide single lead thread, a “click” feature to provide sound and feel to a user so that propelling and repelling can be controlled, and a retention element involving a single slot extending from a central opening through which a screw structure passes upon assembly of the dispenser.

Abstract: A multi-compartmented propel container is provided for a viscous product, such as gels, creams, etc. that maintain separate certain components of the product during storage and allows combination of the components just prior to use. The container includes multiple compartments and a turning mechanism that propels the components of the product simultaneously from the separate compartments into a dispensing outlet where the components come together in admixture and are then ready for application by a user. The turning mechanism also can be structured to allow for repel of the product components, if desired.

Abstract: Dual pack applicators capable of holding two separate volumes of product are described. The respective product volumes are separately accessible from opposite ends of the applicator. The applicator has an outer sleeve which holds two individual applicator assemblies. Each individual assembly has its own reservoir and dispensing mechanism and can be a pre-existing self-sufficient applicator. Each individual applicator assembly is secured within the sleeve by a friction fit or by a snap fit mechanism.

Abstract: A screw operated stick applicator providing for controlled dispensing of a product in predetermined increments based on a click action mechanism. A tubular body holds a supply of product, which is dispensed by the action of a dispensing screw having a control member adjacent the base wall of the tubular body and a threaded shaft inside the body. The shaft is threadably engaged to a movable product support. Protrusions on the dispensing screw interact with the base wall of the body to provide resistance to the smooth rotation of the control member and cause the control member to favor certain predetermined positions. The base wall includes an inner wall surface at its lower end which interacts with the protrusions to provide click action and, thus, controlled incremental dispensing.
