Abstract
A tape for sealing a dispensing opening in a container. The tape is permanently bonded at one end to the container adjacent a dispensing opening in the container, has an intermediate portion overlying the dispensing opening and sealed to the container wall around the dispensing opening, and a free end portion functioning as a grip. The tape differs from other similar tapes in that it is a laminate of two materials with one of the materials being a load bearing material and the other material being a rubbery material, whereby when the tape is removed from the dispensing opening in the usual manner, the load bearing material is stretched beyond its elastic limit and thus when the tape is released it will automatically coil up to an out-of-the-way position relative to the dispensing opening.
