An apparatus for reshaping a container includes a mold of the split type. The container has a body member, a closed lower end member and a cone-shaped open upper end member. The mold has a pair of upper clamping members and a lower clamping member which slide along a liner. The upper clamping members and a seal for closing the container act on the double seam between the upper end member and the body member, thus ensuring that the upper end member and the double seam do not deform during reshaping. The seam between the lower end member and the body member is gripped between the lower clamping member and a support member. During reshaping, compressed air is supplied to the interior of the container, causing it to expand outwardly while the clamping members move inwardly.
An apparatus for reshaping a hollow container having first and second ends, at least one of said first and second ends being open, said container comprising a body member and at least one end member joined to the body member by a double seam, said apparatus comprising a mold having an inner surface which defines a chamber for accommodating the container, first clamping means for clamping the container at said first end thereof with respect to the mold, second clamping means for clamping the container at said second end thereof with respect to the mold, means for sealing the or each open end of the container, means for supplying a fluid under pressure to the interior of the container so as to expand the container outwardly onto the inner surface of the mold, and means for preventing the or each double seam from deforming during expansion of the container.
A method of reshaping a hollow container having first and second ends, at least one of said first and second ends being open, said container comprising a body member and at least one end member joined to the body member by a double seam, said method comprising the steps of placing the container in a mold having an inner surface which defines a chamber for accommodating the mold, clamping the container at said first end thereof with respect to the mold, clamping the container at said second end thereof with respect to the mold, sealing the or each open end of the container, supplying a fluid under pressure to the interior of the container so as to expand the container outwardly onto the inner surface of the mold, and preventing the or each double seam from deforming during expansion of the container.
