Decal Assembly for Inside-Outside Application Having a Reflectorized Surface

It is realized that various types of decals have been provided heretofore. These have invariably consisted of a pictorial or symbol representation having a press-on adhesive secured to its back side, but none have featured a composite structure such as can be adhered either to the inside or the outside of a window simply by separating the components and rearranging them in a prescribed sequence.

The invention comprehends the provision of a novel composite decal assembly having sections arranged in a stack such that by peeling them apart they can be reassembled to self-adhere on the inside or the outside of a window or the like.

The invention comprehends making a multi-sheet assembly including a decal having its back side coated with a pressure-sensitive releasable adhesive which adheres to a first plasticized backing sheet to one side of which the adhesive side of the decal is temporarily adhered, the opposite side of the backing sheet being releasably adhered to a second backing sheet which is adhesively coated on its front side, the rear side of the second backing sheet having no adhesive on its back side, both backing sheets being dimensionally in both length and width preferably larger than the decal, so that when both sheets are separated from the decal it may be adhered directly with the adhesive on its back side to an opposing support surface, and alternatively, the two backing sheets may be separated and the adhesive side of the decal centered on the adhesive side of the second backing sheet and adhered thereto, the marginal edge of the second backing sheet providing a tacky margin about the edge of the decal, and may thus be adhered to the internal side of a window.

These and other objects and advantages inherent in an encompassed by the invention are disclosed in the specification and drawings, wherein:

FIG. 1 is a perspective view of the invention showing the sheets partially peeled apart;

FIG. 2 is a cross-sectional view taken substantially on line 2--2 of FIG. 1;

FIG. 3 is a cross-sectional view similar to FIG. 2, showing the mounting of the decal on the outside of a window;

FIG. 4 is a cross-section showing mounting of the decal with the rear backing sheet on the inside of the window;

FIG. 5 is a perspective view showing the parts in assembled condition;

FIG. 6 is a cross-sectional view on line 6--6;

FIG. 7 is a cross-section showing the decal adhered to the backing sheet and the backing sheet adhered to the outside of the window;

FIG. 8 shows the rear backing sheet adhered to the back of the decal and at its margins adhered to the interior of a window.

The invention as depicted in the drawings comprises a decal 1 made of reflective aluminum or metal foil 2 which has a swirled reflective face 3 upon which there is imprinted a picture or other indicia 5 which is herein shown as a flag upon a shield 7.

The back side 8 of the decal is provided with a pressure-sensitive adhesive A which is centered on a front face 10 of a first backing sheet 12 which is larger dimensionally lengthwise and widthwise to provide a marginal edge portion 13 forming a peripheral frame about the decal. The front face is covered with a coating of plastic such as polyethylene so that the sheet 12 may easily peel off from the adhesive A.

The rear side 14 of the first backing sheet 12 is provided with pressure sensitive adhesive B which is peelably adhered to the front face 15 of the second backing sheet 17, which is coated with a coating of plastic such as polyethylene. Both sheets are made of paper and the back side of each sheet is porous, uncoated and rough textured so that the adhesive clings thereto.

In order to mount the decal in both FIGS. 4 and 8 the intermediate or front backing sheet 12, which is of the same size as the rear sheet 17, is stripped off from both the decal and the rear sheet. Sheet 12 is then inverted or rotated 180.degree. and the adhesive B is then adhered to A, care being taken to center the decal on sheet 17. The marginal edge portion 13 of sheet 12 is then pressed toward the window as seen in FIGS. 4 and 8 and the adhesive B is adhered to the internal surface 19 of the window 22.

FIG. 7 shows an alternative method of external application. In this method the rear sheet 17, which may be translucent plastic, is removed, exposing adhesive B which then is pressed against external surface 20 of the support such as a window.
