DESCRIPTION:
BRIEF SUMMARY
BACKGROUND
According to Robert T. Maleeny and William F. Palmer, Environmental Odor Control, Soap/Cosmetics/Chemical Specialties for January 1991, pp. 28-31, malodors are usually caused by chemicals that are perceived at very low concentrations. Although malodors may not be dangerous to health at low levels, they can affect one's enjoyment of the environment. Maleeny and Palmer disclose that the perfumers of ancient Egypt and Medieval Europe practised masking by deodorizing through the use of perfumes, colognes and sachets. The authors also suggested that foot care can be one of many applications for malodor counteractants. However, there are few, if any commercially available perfume deodorizers in which the perfume component of the deodorizer can be releasably attached to and removed from the interior of a shoe, and still provide sufficient perfume to mask foot or shoe odors. Part of the problem of constructing such a deodorizer lies in the relatively high loading of fragrance in the component containing the perfume (ie. about 10 milligrams (mg) or greater) necessary to mask the foot and shoe odors. Such concentrated loadings of fragrance in the perfume component can cause the adhesive holding the deodorizer to the footwear to soften, causing the deodorizer to loosen from the footwear. In view of the foregoing, it would be desirable to provide a convenient deodorizer for masking foot and shoe odors in which the perfume component could be easily applied to and removed from the shoe interior. It would also be desirable to provide a deodorizer for masking foot and shoe odors through controlled release of fragrance.
SUMMARY OF THE INVENTION
In one embodiment, the present invention is directed toward a deodorizer for masking foot and shoe odors, comprising: odors, wherein the patch is held in place within the retainer opening by contact of the edge of the fragrance patch with the edge of the retainer opening.
Preferably, the retainer and patch are circular in shape. Also preferred is that the means for securing said retainer to the interior of a shoe is a pressure-sensitive adhesive. In a more preferred embodiment, the patch is made from a carrier containing a mixture of fragrance and polymer binder. Preferably both the carrier and the retainer are made of a non-woven felt, such as derived from polypropylene fibers. Also preferred is that the amount of fragrance in the patch ranges from about 10 milligrams or greater. Also preferred is that the polymer binder is polyvinylpyrrolidone.
In another embodiment, the present invention is directed towards an insole/deodorizer for cushioning a foot and deodorizing foot and shoe odors comprising: odors, wherein the patch is held in place within the insert opening by contact of the edge of the fragrance patch with the edge of the insert opening.
In yet another embodiment, the present invention is directed toward a method for deodorizing foot and shoe odors comprising attaching to the interior of a shoe a deodorizer, wherein the deodorizer comprises: odors, wherein the patch is held in place within the retainer opening by contact of the edge of the fragrance patch with the edge of the retainer opening.
In yet another embodiment, the present invention is directed toward a method for cushioning a foot and deodorizing foot and shoe odors comprising inserting into a shoe an insole/deodorizer wherein the insole/deodorizer comprises: odors, wherein the patch is held in place within the insert opening by contact of the edge of the fragrance patch with the edge of the insert opening.
The present invention has the advantage of masking undesirable odors in a shoe by the controlled release of fragrance lasting over a normal day's wear. A second advantage is that the controlled fragrance release can be triggered by moisture from the foot, thus minimizing fragrance loss from the patch prior to application to the foot or footwear. Where a felt carrier is employed, a third advantage of present invention is that it reduces the tackiness at the exposed surface of the fragrance patch.
