ABSTRACT:
A container with a tamper-resistant closure system has a minimum umber of simple parts yet effectively has a tamper-resistant function. A container neck has an annular flange spaced from an upper opening. A locking ring is positioned surrounding the neck below the annular flange and has a hook element that extends upwardly past the annular flange. A cap closes the upper opening of the neck and has an annular lip at an open end, a notch formed in the lip having a width slightly greater than the width of the hook element. The hook element passes through the notch and then engages the annular lip to prevent detachment of the cap unless the hook element and notch are aligned. The locking ring may have an inwardly-extending radial flange which passes through a cut-out in the annular flange to allow the locking ring to be moved into position. Preferably, internal threads are provided in the cap cooperating with external threads on the neck, and cutouts may be formed in the external thread aligned with the cutout in the annular flange.
