A durable, lightweight sign or display device having a desired three-dimensional, contoured surface and a self-sticking backing to facilitate easy mounting is disclosed. The sign has a rigid plastic display sheet which is formed into the desired three-dimensional, contoured surface and formed with a peripheral flange. A plastic backing is heat-sealed to the display sheet along its peripheral flange. Pressure-sensitive adhesive is applied to the outer surface of the backing and a removable protective layer is used to cover the adhesive to prevent contamination thereof prior to use. The sign is relatively inexpensive to fabricate and mass-produce. The sign is ideally suited for temporary display purposes such as sales, promotions, or seasonal decorations.
A sign comprising a rigid plastic display sheet having a desired three-dimensional, contoured display surface formed thereon, the display sheet being secured to a planar plastic backing and together with the planar plastic backing defining a space therebetween a rigid foamed plastic at least partially occupying the space between the planar plastic backing and the display sheet, the rigid foamed plastic having sufficient rigidity to provide support and dimensional stability for the contoured display surface of the display sheet, and matter contained within the space between the display sheet and the backing, said matter having a display surface, a portion of the display sheet being transparent to allow viewing of said display surface of said matter contained within the sign.
A sign comprising a rigid plastic display sheet having a desired three-dimensional, contoured display surface and a peripheral flange, the display sheet being fused to a planar plastic backing along the peripheral flange and together with the planar plastic backing defining a space therebetween, a rigid foamed plastic at least partially occupying the space between the planar plastic backing and the display sheet, the rigid foamed plastic having sufficient rigidity to provide support and dimensional stability for the contoured display surface of the display sheet, and matter contained within the space between the display sheet and the backing, at least a portion of the display sheet being transparent to allow viewing of said display surface of said matter contained within the sign.
A sign comprising a rigid, plastic display sheet formed in to a desired three-dimensional, contoured display surface and formed with a peripheral flange, a plastic backing heat-sealed to the display sheet along the peripheral flange and together with the display sheet defining a space therebetween, a rigid foamed plastic at least partially occupying the space between the planar plastic backing and the display sheet, the rigid foamed plastic having sufficient rigidity to provide support and dimensional stability for the contoured display surface of the display sheet, pressure sensitive adhesive applied to at least to a portion of an outer surface of the backing, a removable protective layer which covers the portion of the outer surface of the backing having the pressure sensitive adhesive applied thereto, and printed matter contained within the space between the display sheet and the backing, at least a portion of the display sheet being transparent to allow viewing of the printed matter contained within the sign.
