ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention concerns a packaged skin product which includes an adhesive dermal patch packaged within an outer container providing potential customers an accurate representation of the enclosed patch.
2. The Related Art
Dermal patches have been available to the public for a number of years. These devices deliver chemicals to the skin for improving its condition.
Illustrative of the art is U.S. Pat. No. 5,785,978 (Porter et al.) which describes use of transdermal delivery devices known colloquially as patches adhering to the skin of an individual. These allow for sustained release of an active ingredient. The devices are said to be useful for improving the appearance of aging or photodamaged skin. Alpha-hydroxyacids and vitamins such as Vitamin C are suggested as suitable actives. A variety of shapes to fit various areas of the face are illustrated in the drawings.
WO 97/48387 (Fotinos) assigned to Lavipharm Corporation discloses use of pressure-sensitive adhesive patches in the treatment of acne. The Examples describe the patches as multi-layer laminates of circular shape (size of 1 cm
2
) formed as a siliconized polyester film coated with an acrylate adhesive containing active ingredient. A film of polyethylene serves as a backing. The resultant circular dots spacedly disposed on the backing layer are then further packaged in a laminated sealed pouch. Several of these pouches are then packaged within a carton. These patches are available under the trademark Vichy. They are advertised for the treatment of pimples and blemishes. Ordinarily the patches number from 2 to 12 units attached onto a peelable backing sheet.
Potential customers have no way of knowing the physical nature of the product prior to purchase. Encasement by pouch and then outer carton hides the patches from view. It would be advantageous to educate customers about the product form prior to the purchase.
Accordingly it is an object of the present invention to provide a skin treatment product packaged to deliver dermal patches held within an outer container permitting the potential customer to visualize the patch.
SUMMARY OF THE INVENTION
A packaged skin product is provided which includes:
(i) at least one regular or irregular polygonal shaped patch for adhesive application to the skin; and
(ii) an outer carton being formed of a plurality of walls for containing the at least one polygonal shaped patch in a manner preventing viewing of the patch from outside the walls, and one of the walls including a window of a size and shape identical to one of the patches.
Ordinarily patches of this invention will include a plastic layer and an adhesive layer. A backing sheet is used as a support onto which the patches adhere. Advantageously about 4 to about 30 patches are adhesively positioned on a single backing sheet. More preferably about 6 to about 12 patches are placed per single backing sheet. Each of these sheets may then be enclosed within a sealed pouch. Typically the pouches are of laminate construction and heat sealed to exclude moisture.
Patches of this invention may contain cosmetic skin treatment actives formulated within the adhesive layer. Acrylic hydrogels are the most preferred form of adhesive.
Windows and patches of this invention preferably are of a round configuration. Alternative shapes are not excluded and may be rectangular, square, star-shaped, semicircular, rectangular or of non-regular borders.
In a first embodiment, an at least translucent plastic strip is held against an inner surface of the one wall and covers the window. Plastic strip and patch preferably have about an equivalent light transmission. Equivalence of light transmission and shape allows a potential purchaser to visualize the patch without the necessity of exposing it to atmospheric moisture. Information can be placed on an outer surface of the one wall, especially directly below the window, advising purchasers that the window represents the actual size of the patch. These windows and patches will normally range from about 0.5 to about 10 cm, preferably from about 0.8 to about 3 cm, more preferably from about 1 to about 2 cm, optimally about 1.5 cm. Light transmittance of the patches are very close to transparent but visually have a matte finish appearance.
