Embodiments of a tamper-evident closure are disclosed which prevent unauthorized access to a container and its contents, deterring adulteration or introduction of counterfeit product. In one embodiment the tamper-evident closure can be fitted to an associated container and closure, and includes a portion which is removed by fracture of the tamper-evident closure to gain access to the container closure. In another embodiment, an arrangement of wedge-like tongues permit fitment of the tamper-evident closure to associated container for temper-evidence. In another embodiment, the tamper-evident closure is joined by frangible bridges to the container closure to provide the desired tamper-evidence. In another embodiment, the tamper-evident closure is movable axially of the associated container closure to thereby provide evidence of removal.

A closure device for a container having a neck including an annular flange, the closure device comprising: a cap body; a tamper evident (TE) band positioned below the annular flange when assembled in the container; a first hinge and a second hinge defined on the cap body; a leash connected to the TE band, the first hinge and the second hinge; the leash allowing for the cap body to be separated from the TE band during opening, but to remain connected thereto via the leash; a tongue protruding from the cap body between the first and second hinges; when the cap body is actuated from a closed configuration relative to the neck to a fully open position: the leash is configured to retain the cap body to the TE band; an interaction of the tongue and the neck is configured to retain the cap body in the fully open position.

A securing ring is snap-fittingly engageable over and around an annular mounting flange of a foldable pouring spout in a container closure assembly, with a frangible connection between the securing ring and a spout closure member (e.g. a screw cap) intact. The assembled closure assembly is snap-fittingly engageable over and around a container neck which is received in a groove extending circumferentially about the mounting flange. The groove is defined in part by a radially outer wall having a proximal portion lying towards the pouring end of the spout and a distal end portion lying away from the pouring end of the spout. The radially outer wall comprises a central flexure zone of reduced radial width relative to the proximal and distal end portions, whereby the distal end portion is hingeingly deflectable between a radially outer position for extraction of the spout from a mold tool, and a radially inner position for engagement in an annular undercut in a radially outer surface of the container neck. When the securing ring is snap-fittingly engaged over and around the mounting flange, the distal end portion is held in the radially inner position. The distal end portion comprises a chamfer at its radially inner side and which extends radially inwards towards the pouring end of the spout for guiding the closure assembly into snap-fitting engagement with the container neck.
