Apparatus and method for forming a container

摘要

The combination of a carrier for a container, a squaring plate, a drive for the squaring plate, and a sealing assembly. The carrier accepts a container having first and second spaced flat walls that are substantially parallel to each other with the container in an erected state and third and fourth walls each connecting between the first and second flat walls. The carrier has a first edge against which the first wall of the container can be abutted so that the first wall is thereby supported in a first orientation with the container operatively held by the carrier. The squaring plate is guided in movement relative to the carrier towards the first edge. The squaring plate has a guide edge for engaging the second wall of the container operatively held by the carrier as the guide edge moves relative to the carrier towards the first edge and thereby repositioning the second wall relative to the first wall as an incident of which the first wall is urged toward the first orientation and the first and second walls are urged into substantially parallel relationship with each other. The sealing assembly has a sealer element that is guidingly advanced towards and against a part of the container operatively held by the carrier to thereby reconfigure and close the part of the container operatively held by the carrier.
