-- A B S T R A C T -- Disclosed is a tamperproof package comprising a container sealed by means of a turn-off type cap wherein the container has a circumferential sealing finish with a sealing rim at the upper end of the circumferential finish and including cam surfaces with a locking shoulder there- below on the circumferential ceiling finish. The closure cap includes a top wall with a peripheral skirt depending therefrom and having internal camming surfaces for mating engagement with the cam surfaces on the circumferential finish of the container. One or more locking lugs or de- tents are flexibly connected to the skirt for flexing in radial planes toward and away from the axis of the con- tainer with the locking lugs or detents and adjacent edges of the skirt having interlocking tongues and sockets to retain the locking lugs or detents engaged with the locking shoulder of the container. When the cap is turned for re- moval the cam surfaces urge the cap upwardly with the engagement of the locking detents with the shoulder provid- ing a camming action that forces the detents radially out- wardly, breaking or damaging the tongues and visually indicating the breaking of the seal. The locking detents and all portions of the closure cap remain as a removable unit for reuse or disposal with no separable portions remaining on the container or otherwise requiring disposal.
