Sunbeam A-309 ABSTRACT OF THE DISCLOSURE A child-resistant, tamper indicating package includes a container having a body portion with a tubular neck and a closure for the neck which is removable and re- closable. The container has a shoulder at the juncture of the body and the neck and the neck has a radially outwardly extending annular rib spaced from the shoulder. The rib has opposed upper and lower converging surfaces such that the included angle at which the lower surface intersects the tubular neck is greater than the included angle at which the upper surface intersects the tubular neck. The closure has a disc-shaped top and a flexible annular skirt the lower edge of which is formed with an inwardly directed flange. The inside diameter of the flange is less than the outside diameter of the rib on the neck so that the flange engages the upper surface of the rib to flex the skirt radially outwardly during downward movement of the closure on the neck until the flange snaps beneath the neck rib to hold the closure in sealing engagement with the neck. The greater lower angular surface prevents manual removal of the closure without a tool. Provision for the use of such a tool is provided by a space between the lower lip of the skirt of the closure and the shoulder on the container. A tear strip extends at least partially circumferentially around the closure skirt in the close proximity to the shoulder to prevent insertion of the tool and to conceal the space in which the tool can be inserted. Upon removal of the tear strip, a tool can be inserted for prying off the closure.
