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

A closure device for a container neck having a cap which is pivotable between closed open configurations, comprising: a base; an outer wall extending circumferentially around the base; a plug seal extending from the base, at an inner face of the cap, and spaced from the outer wall to define a channel for receiving the container neck and for forming a seal against an inner wall of the container neck when the cap is in the closed configuration; a lifting member extending from the base and positioned radially inwardly from the plug seal, the lifting member being positioned at a pivot-side of the cap and having a contact face at a free end of the lifting member for contacting a top end of the container neck before the top end contacts the plug seal during actuation of the cap from the open configuration to the closed configuration.

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.

A closure () with a shell () for securement to a container neck () and a lid () pivotally connected to the shell () by a pair of hinge elements (). A hinge line () in the side wall () delineates a deformable latch () having an external grip tab () and an internal engaging tab () between the grip tab () and a top wall () of the lid (). The grip tab () extends radially from a side wall () of the lid () and the engaging tab () engages a lip () surrounding the mouth of the container neck (). The deformable latch () is configured to deform along the hinge line () when an opening force is applied to the grip tab (), thereby to disengage the engaging tab () from the lip () of the container neck ().

Closure for a container neck

Closure cap

The present invention provides a closure cap for a container comprising a lid and a shell, and a hinge region for pivotally connecting the lid to the shell and for locking the lid in an open position thereof. The lid comprises a top panel having a tongue adjacent the hinge region and a cylindrical wall suspended from a bottom face of the top panel and connected to the shell via a plurality of bridges which break upon a first opening of the lid. The hinge region comprises a pair of elongate hinge elements spaced apart from each other, and a ratchet-like member disposed therebetween.
