Dispenser with turn cap

Abstract

Abstract A small dispenser of the type intended to be held in the hand, for discharging various substances such as powdered talc or other fine particulate material, granulated substances and the like, as well as certain viscous substances. The dispenser comprises a plastic container or small jar having a transverse top wall provided with a large central opening and with a plurality of discharge openings (or a single opening) disposed radially outward of the central opening. Turnably mounted on and engaged with the transverse top wall is a captive cap having similar dispensing openings (or single opening) adapted to be registered with the corresponding openings or opening of the transverse container wall when the cap is properly rotatably positioned. The cap has a centralized depending bearing and retainer skirt which is adapted to fit into the large central opening of the transverse wall of the container, said skirt having a detent bead or shoulder means around its bottom rim. One of the parts, preferably the cap, is of resilient or yieldable plastic substance, whereas the other is preferably of a more rigid plastic composition, the arrangement being such that the cap can be press or snap fitted to the container by forcing the depending skirt thereof with its detent bead into and through the large central opening of the transverse container wall at the top. To facilitate such snap type assemblage, the central opening of the transverse wall is made tapered or with sloping edges which tend to cam inwardly the detent bead of the depending skirt of the cap as the latter is forced downward onto the container, whereby the detent bead is radially compressed or reduced in size and forced completely past the bottom edge of the large wall opening. Upon this occurring, the detent bead radially expands to its original shape, whereby it effectively locks the cap to the container top while permitting the cap to be turned with respect thereto. At the underside of the cap there is a stop lug which is received in a movement-limiting slot of the transverse wall, the slot being so arranged that for one stopped or limited position of the cap the discharge openings thereof are out of registration with those of the top wall of the container. For the other limiting position, the discharge openings of both parts are in registration, enabling dispensing of the contents of the container to be effected. The assemblage of the cap to the container is very quickly and economically effected, without requiring separate fastenings of any kind, or additional operations to be performed on either the container or the cap.
