Abstract

A method for applying an end plate to a container body includes applying a heated end blank made of deformable material to one end of the container body and creating a pressure difference between the two sides of the end blank to seal the edges of the end blank to the edges of the container body. The apparatus for applying an end plate to a container body includes a jacket having a chamber into which the container body can be fitted. A vacuum source is provided at one end of the jacket and a lid or clamping device is located at the opposite end of the jacket. The chamber into which the container body is fitted is not as deep as the container body so that when the container body is fitted into the chamber, the upper edges of the container body extend above the surface of the jacket. In that, the end blank can be applied to the container body and thereafter, the clamping device is used to clamp the end blank between the upper edge of the jacket and the clamping device. A device is then utilized to create a pressure differential between opposite sides of the end blank to seal the end blank to the container body.
