A can for packaging food, comprising a metal can body and a diaphragm lid () formed of lidding material which comprises a multilayer structure with at least an aluminum layer of from 6 to 90 microns thickness and a bond layer for fixing the lid () directly to the can body. One method for forming the can forms the lidding material by using an outwardly extending curl () at one end of the metal can body as the draw die. Lidding material which is carried by the body maker punch is drawn around the curl of the can body draw die so as to form the lidding material into a cup shape.

Packaging can and method and apparatus for its manufacture

Aerosol can body

In a method of fitting a top or a bottom to the body of a can, the top or bottom is placed inside a die having a rolling surface. The top or bottom has an inwardly rolled edge defining a support surface adapted to be substantially mated with at least part of the rolling surface. An end portion of the can body is inserted between this rolling surface and this support surface. Thrust is then applied to the can body until it causes the end portion to roll around and envelop the support surface. The corresponding machine comprises at least one rolling die incorporating a bush defining a first rolling surface facing radially inwards and a plurality of jaws disposed along a perimeter corresponding to the shape of the can. The jaws are movable towards an inside wall of this bush and are shaped to define at least part of a second rolling surface which faces radially outwards. This second rolling surface is adapted to form an extension of the first rolling surface when the jaws are positioned close to the inside wall of the bush.
