Abstract: A metal end is applied and sealed to a plastic or paper/plastic composite container body by a crimp-seaming or double-seaming operation. The metal end has an outer curl joined to a compound-angle chuck wall that extends down from the curl. The chuck wall has an upper part that is substantially linear and at an angle ?1 with respect to an axis of the end, and a lower part that is substantially linear and at a larger angle ?2 with respect to the axis. The compound-angle chuck wall allows a substantial diametral clearance between a lower end of the lower part of the chuck wall and the inner surface of the container body, while there is substantially zero clearance, or preferably an interference fit, between the upper part of the chuck wall and the inner surface of the container body. Accordingly, the chuck wall guides the end into concentric alignment with the container body during application.

Abstract: A method of sealing a peelable lid (2) to a flange (4) provided within a metal can body (1) which involves inserting an induction coil (6) into the can body to primarily heat the sealing surface (5) of the flange, whilst keeping the exterior wall of the can relatively cool to avoid tin reflow and decoration degradation of the exterior wall. The induction coil is subsequently removed from the can body and a peelable lid applied to the flange, whereby residual heat in the flange aids the sealing of the lid to the flange, e.g. by allowing activation of a bonding material.

Abstract: In can production, a press apparatus is provided for tightly connecting a first contact surface of the can wall running around an axis to a second contact surface of a base, a lid or a closure membrane. If the press parts (16) are arranged essentially fixed in the axial direction or are held in a radial guide and can be moved radially by an actuating element (8) displaceable in the axial direction, the can need not also be moved during pressing.

Abstract: A method for preparing a glass container, and for sealing a glass mouth of a container and the seal are described. The sealing surface, or finish, of the container is subjected to a hot end treatment after forming and before annealing to enhance adhesion between the container finish and a thermoplastic membrane seal. The container is next annealed and after annealing is subjected to a cold end treatment in which the exterior container surface is coated with a material which enhances the lubricity and increases the abrasion and scratch resistance of the container. The container finish only is then subjected to a brief heat treatment sufficient to remove any lubricity enhancing material from the finish. A membrane comprising a thermoplastic film is pressed onto the container finish and heated causing glass-plastic adhesion and forming a closure.
