Disclosed is a device and method for forming a curl in a closable container. A process of forming a pre-curl is used, which is followed by a second separate step of forming the completed curl. The two-step process provides for higher tolerances with respect to the shape of the curl that allows the curl to be used as a sealing surface for a recloseable metal bottle. A three-step process provides for even greater tolerances and reduces longitudinal forces by completing the curl using lateral forces.

Apparatus and method for forming (e.g. die necking) open ends of open-ended metal container bodies. An exemplary embodiment provides a number of movable holders for container bodies that move the container bodies along a path extending through the apparatus. A motor advances the holders and container bodies along the path in steps with pauses between each step. Each step advances one or more container bodies (and preferably two or more). One or more groups of work stations positioned adjacent to the path provides tool sets for carrying out a forming operation on one (and preferably two or more) container bodies simultaneously. Individual container bodies, or more preferably groups of two or more, are subjected to one or more forming operations during passage along the path (preferably the periphery of one or more star wheels).

A container end member is provided and has a first severable tab portion which is defined by a score line groove and has an integral hinge portion for permanently securing it to the container end member and a force applying tab portion permanently pivotally mounted on the container end member and used to apply a force on the first severable tab portion to form a pour opening in the container end member and a second severable tab portion having an integral hinge portion for permanently securing it to the container end member and having a raised surface projecting outwardly from the container end member so that a force may be applied thereto to sever the second severable tab portion and form a vent opening in the container end member.

A container end member having a peripheral wall portion and an integral central wall portion is provided and which has at least one severable tab portion integral with the central wall portion and having a hinge portion having spaced apart ends and wherein a recessed portion is formed between the central end wall portion and the severable tab portion and has an axial thickness less than the axial thickness of the remaining portions of the central end wall portion and the severable tab portion and at least one severable score line groove having a main body portion and integral end portions defining the spaced apart ends of the hinge portion is formed in the recessed portion and at least a portion of the at least one score line groove extends in a transverse direction in the recessed portion. Also, apparatus is provided for controlling the amount of force applied to a container end member during the formation of a score line groove therein.

The disclosed invention describes a container end that can be easily opened and does not rely on a conventional metal tab, riveted onto the end, thereby avoiding the problems and the cost associated with such a tab. The invention utilizes a traditional container end shell with a separate and distinct piece that is formed independently and is inserted into a countersink which is placed on the outer surface of the container end shell. The removal of this separate piece exerts a force or causes a change in the properties of the container wall in the countersink area, initiating and proliferating a discontinuity in the container wall, thereby creating an opening in the container. This change in the properties of the container wall can be mechanical, chemical, thermal or any other modality, which has the ability to influence the integrity of the container wall.
