Closures with a tamper evidence feature that is reshaped to connect it to the container neck are disclosed. Methods and systems for carrying out the methods, and to mold stacks for making the closures are also disclosed. The tamper evidence feature can be a band, a portion of a cylindrical skirt or a panel formed in the cylindrical skirt. The application of heat may deform the band inwardly to create a lip for engaging a flange on the container neck, or it may weld the tamper evidence feature to the flange.

Closures with tamper evidence

Method of securing a closure on a container

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.

Closure device for a container

A closure for sealingly closing a container neck having a tubular body with a top wall, an annular side wall, an intermediate wall joining the side wall to the top wall and an annular tamper evidence band frangibly connected to an open end described by the side wall. The band includes retaining cams protruding from its inner surface. Each cam has a lead-in ramp for engaging, in use, the flange of a container neck as the neck is introduced into the open end of the body and a stop for engaging the flange to separate the band from the body when the closure is subsequently removed from the neck. Each lead-in ramp has a central recess therein.
