  • Patent number: 5547465
    Abstract: A finger patch with a pressure-sensitive adhesive backing, is a molded solid rubber body which is concave in the undeformed condition, and has a relatively thick mid-portion and a relatively thin edge entirely surrounding the body. The outer surface of the edge is disposed at an acute angle to the underside of the body that contacts the fingertip of the user, thereby to avoid catching of the patch on the edges of papers handled by the user. The patch has a thickness of the thickened mid-portion of 0.023 to 0.049 inch, a Shore "A" hardness of 43-47 and a concavity of about 1/8 inch in its undeformed condition. A release paper covers the pressure-sensitive adhesive, the finger patch being oval and the release paper having a tail that extends from only one end of the oval finger patch.
