A removable tab for metal/air cell, particularly miniature zinc/air button cells which have a principal use as hearing aid batteries. The tab covers air holes in the surface of the cell. The tab has a stiff elongated member that has an extended portion which forms a handle for removing the tab from the cell in order to activate the cell. The tab also comprises a resilient material, preferably a polymeric foam. A portion of the resilient material is adhered to at least a portion of one side of the stiff elongated member and another portion of the resilient material is adhered to cover air holes in the cell surface. A polymeric film can be inserted between the foam and cell surface. The resilient material conforms better to the cell surface which can typically have curved, grooved or depressed regions in addition to the air holes. The resilient material provides more uniform adhesion of the tab to the cell surface with releasable pressure sensitive adhesives. |
