Z-tab innerseal for a container and method of application

摘要

A z-tab innerseal for a container and method of application involves an innerseal having a first sealing portion for sealing a first portion of an opening defined by an upper rim of a container, a second sealing portion for sealing the remainder of the container opening and a flap portion between the first and second sealing portions which is adapted to be grasped and pulled upwardly by a user to remove the innerseal from the container opening. An advantage of the flap portion is that it allows the innerseal to be removed without having to penetrate or scrape the innerseal with a sharp object such as a knife. A method of forming the improved innerseal includes providing a blank of stock material having a folded portion, cutting the blank to form an innerseal, mounting the innerseal onto the rim of a container and sealing the innerseal to the container by passing the assembly through a heating station.
