Abstract
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 reclosable. 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 a manual removal of the closure without a tool.
