INTERNALLY DELAMINATING TABBED INNERSEAL FOR A CONTAINER AND METHOD OF APPLYING

摘要

An improved innerseal for sealing containersincludes a body portion (22) having an upper surfaceand structure (24) connected to the upper surface forgrasping by a user, whereby the body portion may beremoved from a container quickly and efficiently. Thebody portion includes structure for preventing passageof fluid therethrough, and structure for bonding thebody portion against the upper rim of the containerwith a first bonding force. The bonding structure has afirst bonding portion for sealing against the containerrim and a second bonding which is adhered to the firstbonding with a second bonding force which is greaterthan the first bonding force. Consequently, a first partof the first bonding portion will delaminate from thesecond bonding portion over the container rim and re-main adhered to the rim, while a second part of thefirst bonding portion will remain adhered to the sec-ond bonding portion, thereby exposing the opening inthe container when the grasping structure is pulled. Amethod for manufacturing containers so sealed is alsodisclosed.
