Dispensing closure employing standards with bearings to receive spout

Abstract

A dispensing closure consisting of a cap with a cavity defined in its upper surface, and a spout to fit within the cavity. The spout has an enlarged base, and a central passage extending through the base and the remainder of the spout. Aligned trunnions are formed on the opposite sides of the base of the spout. An opening in the cap allows communication between the container upon which the cap is seated and the central passage in the spout. A pair of standards are integrally molded within the cavity in the cap, and one standard is situated on each side of the opening. A U-shaped bearing, with a slightly restricted opening, is located at the upper end of each standard and spaced fingers define the entrance into each bearing. The trunnions are forced downwardly into the opening in each bearing. The fingers deform momentarily to accept the trunnions and return to their unstressed condition to capture same, thus securing the spout to the cap and exerting a downwardly directed force upon the spout. The spout is mounted for pivotal movement between a closed position, and an opened position, which permits the discharge of the contents of the container. The sealing characteristics are materially improved by the addition of a flexible sealing flange surrounding the upper side of the opening through the cap.
