ABSTRACT:
A method and apparatus for lining the interior of a container with plastic sheet material. An open topped container is elevated upon a support through a passage in a lower die member into contact with the under surface of a sheet of heated thermoplastic material overlying the upper end of the passage. A plug assist member is then employed to deform the sheet into conformation with the interior of the container. Upon withdrawal of the plug assist member, an upper die member is lowered into shearing relationship with the lower die member to shear the sheet around the upper periphery of the container. The support, with the lined container in place, is then further elevated to raise the lined container upwardly through the opening thus sheared in the sheet and through a passage extending vertically through the upper die member. The plastic lined container is discharged from the apparatus by pushing it transversely across the flat upper surface of the upper die member.
