  • Patent number: 5938449
    Abstract: A pressure sensitive reusable writing board is provided which includes a backing member that includes an upper section that folds down over the lower section that accommodates the wax layer and polyester writing sheet. As a result, the upper section provides a protective cover for the lower section. A distal edge of one of the upper or lower sections includes a loop which is in registry with a slot disposed in the distal edge of the other of the upper or lower sections. As a result, when the board is folded together to assume a closed position, the loop may be folded forward through the slot disposed in the opposing section or panel and the stylus may be inserted through the loop to lock the board into a closed position. As a result, any writing or artwork made on the reusable writing surface can be preserved while the board is being transported or handled.

  • Patent number: 5791910
    Abstract: A pressure sensitive reusable writing board is provided which includes a backing layer printed with a background color and coated with wax and a single polyester sheet attached to a wax-free strip of the backing and which overlies the wax layer. Pressure applied to a front surface of the polyester sheet causes the sheet to cling to the wax layer thereby showing the writing as a dark color (i.e., the color of the wax) on a white or light background. The white or light background is provided by printing on the undersurface of the polyester sheet with a white opaque finish. Graphics, such as lines, maps or other educational or functional graphics may be disposed on the undersurface of the sheet. The backing may also be mounted onto a larger panel which may include additional informational or decorative graphic presentations.
