Abstract

An easily removable innerseal for a container and method of application relates to an improved arrangement having a body portion (22) adapted for fitting over the upper rim of a container and a flexible element (24) attached to the body portion for a user to grip. The body portion is provided with a lower bonding layer, which includes a first bonding portion (26) and a second bonding portion (28) adhered to the first portion, and a layer (30) to prevent fluid from passing therethrough. The bonding force between the first and second bonding portions is designed to be weaker than the bonding force between the bonding layer and the container. In addition, the rupture strength of the first bonding portion is less than either of the bonding forces. As a result, the force required to remove the innerseal from the container is not dependent upon the amount of heat applied during sealing, because delamination will occur between the two bonding portions in an area over the container rim (14), leaving a residue of the first adhesive portion attached to the rim. By gripping the flexible element and pulling it upwardly, a user can remove the innerseal from the container without having to puncture or scrape the innerseal with a sharp object, which is frequently required to remove innerseals of the type commonly in use today. The method of application includes the steps of applying the body portion of the innerseal around the rim portion of a container and passing the container through an induction type heating station.
