Cutting device

A method of sealing a container, the method comprising:

• cutting a web of electrically conductive material carrying a thermosensitive adhesive, using a linearly displaceable cutting member, to provide a cut portion of the electrically conductive material, and thereafter transferring the cut portion of the electrically conductive material to an open top of a container using the linearly displaceable cutting member, wherein the linearly displaceable cutting member cuts the web of electrically conductive material to provide the cut portion and thereafter transfers the cut portion to an open top of a container in a single linear stroke;
• inductively heating the cut portion of electrically conductive 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 inductively heating the cut portion of the electrically conductive material melts the thermosensitive adhesive carried thereby to seal the cut portion of the electrically conductive material to the open top of the container to seal the container, and further wherein the cutting member is formed from a material which is electrically insulating whereby the cutting member is not inductively heated during said step of inductively heating the cut portion of electrically conductive material.
