  • Patent number: 4832942
    Abstract: The present disclosure is directed to a touch-effective disinfectant tape suitable for mounting on a substrate facility to enable a user to disinfect his/her hand(s) during use of such facility. This tape can be enclosed in a liquid-proof covering, e.g., shrink sealed package, aluminum or other metal foil, etc., and has an upper perforate tape cover layer, a central liquid disinfectant-containing foam layer, a double adhesive-backed lower layer and a bottom release liner. For application to the substrate, the release liner is removed and the bottom adhesive layer is applied to the door knob, door plate, urinal handle, commode handle, or other surface. When such surface is touched by the hands of the person(s) using such facility, the user's hand(s) are disinfected/sterilized without any conscious effort on the user's part to accomplish such.
