  • Dental film packet improvement and method for effecting same
    Patent number: 5077779
    Abstract: A convenience-enhancing improvement upon a known dental film packet (FP) having sensitized film and protective opaque sheets (10 and 12, 14) enclosed by an openable light-tight envelope (16), one of whose opaque sheets (12c) covers substantially all of the film sheet (10) when both (12c and 10) are partially withdrawn after its envelope (16) has been opened, rendering the film sheet (10) inconvenient to grasp and remove alone. In a first embodiment, the improvement comprises shortening said one opaque sheet (12c') so that it (12c') remains sufficiently protective without covering a graspable end portion (10L') of the film sheet (10').
