This invention relates to a novel bandage and the construction thereof for providing skin tone matching for conventional bandages. In particular, the present invention is directed to a low cost method of manufacturing in which the skin tone is applied to one side of an absorbent pad forming the bandage. The absorbent pad is attached to a transparent strip so that the bandage appears very close to the skin tone of the user.
Adhesive bandages having skin tone properties are known in the art. However, skin tone bandages have not been widely accepted because their construction was complicated, and the techniques for skin matching were not adequate. Consequently, these various attempts to hide the bandage have met with only mixed success, and the desire for matching skin tone bandages remains unresolved. Included in prior art attempts are U.S. Pat. No. 2,905,174 ('174) in which a transparent bandage is imprinted along the backing with a plurality of visible flesh colored markings. U.S. Pat. No. 3,687,136 ('136) discloses a bandage with a transparent backing, a gauze dressing, and a piece of colored film there between to obscure the gauze dressing. While the '136 patent might work for its intended purpose, it does not provide adequate skin matching capabilities, and the method of construction is complicated and unsuitable for mass production. U.S. Pat. No. 4,161,176 provides a bandage with many layers releasably secured atop one another. Each layer is a different color. With this construction, the wearer peals off layers to select a desired color.
None of these attempts recognize that a solution to pigmentation could be obtained by imprinted in the gauze portion of the bandage itself, so that extremely simple, and low cost method of construction, is provide, that construction being one in which a variety of skin tones can be present to a user.
In accordance with this invention, generally stated, a cosmetic bandage is provided which includes a transparent backing layer having a top side and a bottom side. A transparent adhesive layer is applied to the bottom side of the backing layer. An absorbent pad having a top side and a bottom side is arranged so that one of the sides has a non-toxic pigment composition applied to it so as to be derma matching and having a melanin likeness and appearance. The composition preferably is applied by flood printing or a silk screening process, in which a dot matrix arrangement is employed to provide improved skin matching capabilities. In the preferred embodiment, the absorbent pad it self provides the dot matrix arrangement. In other embodiments, the dot matrix is provided by the printing method employed for transferring the pigment to the pad. The pigmented side of the pad is attached to the backing layer and is intended to be visible therethrough. The adhesive bandages of the present invention aid in the healing of external wounds or injuries and provide a cosmetic concealment of the wound or injury by color matching and pattern matching the appearance of the human skin or derma.
The objects of the invention are achieved as set forth in the illustrative embodiments shown in the drawings, which form a part of the specification.
Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.
The following detailed description illustrates the invention by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what I presently believe is the best mode of carrying out the invention. As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
Referring now to
The backing layer 2 includes a first side 10 and a second side 12. One of the sides 10 and 12 has a suitable adhesive 5 applied to it. In the preferred embodiment, the adhesive is pressure sensitive, but any suitable adhesive is compatible with the broader aspects of the present invention. The backing layer 2 preferably is transparent tape.
As will be appreciated by those skilled in the art, the backing layer 2 may assume a number of design shapes, and the silhouette of the backing layer maybe altered to conform to the desired shape.
The pad 3 preferably has a pattern construction 16 associated with it, best shown in
As indicated, the pad 3 preferably has the matrix structure 16 associated with it, which permits the pad to have the pigment flood printed or silk screened on the pad. Preferably, the pigment maybe applied in a single step. In the alternative, a number of printing steps may be employed with one or more pigment tones or shades, to provide the proper color for the bandage. The printed side 21 of the pad 3 is then attached to the side 10 of the backing layer 2, so that the pigmented side of the pad 3 appears through the transparent backing 2. As will be appreciated by those skilled in the art, other printing or application processes are compatible with the broader aspects of our invention.
Alternatively, when the pad 3 is not formed with the dot matrix structure 20 initially, a plurality of these steps may be employed to provide the appearance of the pigmented layer.

As shown in
Numerous variations will occur to those skilled in the art in view of the forgoing description of the company drawings. As indicated, the shape and design silhouette of the bandage 1 may vary in other embodiments of this invention. Likewise, while certain techniques for applying the pigment to the pad for described, other methods are compatible with the broader aspects of this invention. The adhesive used in connection with the bandage may change in other embodiments of the invention. These variations are merely illustrative.
In view of the above, it will be seen that the several objects and advantages of the present invention have been achieved and other advantageous results have been obtained.
This application is related to U.S. Provisional Patent Application No. 60/493,169 filed Aug. 7, 2003 from which priority is claimed.
