  • Patent number: 6039185
    Abstract: A thin flexible sheet of PETG or similar plastic has a disk shaped body with a number of radially protruding petals. The outer perimeter of one side of the inserter is coated with a pressure sensitive adhesive. A hearing aid battery with its connected selectively-gas-permeable tab is adhered to each of the inserter petals. Each petal has a small through hole positioned in alignment with the vent hole on the battery, which permits exchange of gases through the semipermeable tab. A battery is inserted into a hearing aid while attached to the inserter by gripping the inserter between the thumb and forefinger, and positioning the battery into an adjacent hearing aid battery compartment and then separated from the inserter by a sliding or wiping motion. The inserter is retained in a container fixed by removable side strips to a backing card.
