ABSTRACT:
A cap adapted to cooperate with a container to seal and unseal the container. The cap comprises a circle-shaped knife carried by an inner surface of the cap and a lid adhesively secured to a portion of the inner surface of the cap. The container is sealed by positioning the cap over an opening of the container, which opening is defined by a container edge, and then securing the lid of the cap to the container edge by induction or conduction. The container is unsealed by exerting pressure on the cap whereby the knife cuts through the lid thereby cutting a circular portion out of the lid and unsealing the container. The circular portion cut out the lid remains adhesively secured to the cap.
