A tubular body provided with a first end wall is filled through the open end thereof and sealed by a second end wall. One of these walls has a hole therethrough closed by a closing means, this wall being initially of generally concave configuration with the closing means disposed entirely inwardly of a plane passing through the rim of the wall. The concave wall is subsequently changed to a generally convex configuration with the closing means disposed at least partially outwardly of the plane.

Method of making a filled container and product

The invention relates to a method of manufacturing a body for a container, in which a body having a weldseam along its longitudinal direction is formed by bending material in sheet form and welding the overlapping edges of the bended material together, and the wall of the body having the longitudinal weldseam is thinned. Preferably thinning is obtained by wall-ironing. It is advantageous that the wall thickness of a wall part close to wall end of the body is larger than that of a remaining part of the body and eventually prior to thinning has been reduced and that prior to being reduced the body is provided with a gripping rim and/or cover.
