Abstract:
1. A method of sealing a container, the method comprising: cutting sealing material carrying a thermosensitive adhesive, using a linearly displaceable electrically insulating cutting member, to provide a cut portion of the sealing material, and thereafter transferring the cut portion of the sealing material to an open top of a container using the linearly displaceable cutting member, wherein the linearly displaceable cutting member cuts the sealing material to provide the cut portion and thereafter transfers the cut portion to an open top of a container in a single linear stroke; heating the cut portion of the sealing material, using an electrical induction coil, following transfer to the open top of the container by the linearly displaceable cutting member and whilst held against the open top of the container by the linearly displaceable cutting member; wherein the step of heating the cut portion of the sealing material melts the thermosensitive adhesive carried thereby to seal the cut portion of the sealing material to the open top of the container to seal the container.
