Abstract
Abstract To close a container having an open mouth, a mass of synthetic resin is adhesively bonded to this mouth and/or positively interlocked therewith to form a seal with or without the aid of a separate cap also engaged by this mass. A flexible element may be projectingly imbedded in the mass to aid in the removal of the seal.
