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 rod-shaped cosmetic material feeding container has a container front portion and a container rear portion which are relatively rotatable in a delivering direction. A piston body is slidably inserted in a closely attached state to an inner portion of the container front portion. A moving body is arranged in a rear side of the piston body within the container rear portion and is provided in an outer periphery with the male thread connecting by screw to a female thread provided within the container rear portion. The piston body and the moving body are separated so as not to be engaged to each other, thereby a cosmetic material can be directly filled in a melting state from an opening portion in a leading end of the container in a state in which only the piston body is arranged at a predetermined position within the container front portion.

Abstract: When rotating a main body tube and an operation tube in a disclosed container toward a first direction, a moveable screw tube advances a predetermined amount. When further rotating toward the first direction, a screwing part urges a moving body forward. A female thread of the screwing part in the moveable screw tube is radially outwardly expandable via a slit. When the moveable screw tube advances toward the first direction, the outer diameter of the front end part is restricted and expansion thereof is prevented. When further rotating toward the first direction and the screwing part urges the moving body forward, expansion of the front end part and the female thread of the screwing part may be suppressed. Accordingly, the screwing part reliably exerts screw function when the moving body advances.
