Abstract
Abstract A container such as a vial for medicines, and a one-piece safety closure therefor. The container is provided with an annular, outwardly extending shoulder or lip adjacent the upper end of the open neck. A one-piece closure, preferably molded from plastic material, has a top wall which includes a central circular section, a downwardly sloping conical section, and an annular flat section which integrally connects to a depending cylindrical skirt section. The interior sidewall of the skirt is provided with an inwardly projecting, preferably beveled, shoulder or lip which, when pressed on the lip or shoulder of the container, snaps over and provides solid engagement of the closure cap with the container. The cap can be removed by applying pressure with one''s thumb to the central section while lifting the peripheral skirt with one''s fingers. In a second embodiment, a container, such as a vial, is provided with a second shoulder below and immediately adjacent to the upper or first shoulder on the vial. The second shoulder has a sloping undersurface and an annular, flat top surface which preferably makes abutment with the lower periphery of the cap skirt preventing engagement of one''s fingers with the lower end of the skirt of the cap, except when the top of the cap is depressed.
