说明书全文 | This patent application claims priory in U.S. Provisional Patent Application Ser. No. 61/577,153 filed Dec. 19, 2011. This invention is directed to the field of perfumery and odor control, and more specifically to a shoe freshener capable of being rejuvenated after use. Odor generating from footwear is a common problem. One of the most common causes of foot odor is perspiration being deposited into the material of footwear. Perspiration contains water, salt, urea, and fatty acids. When these ingredients combine with microorganisms on the skin, the organisms can reproduce and grow in the footwear so that the footwear contains growing bacteria and fungus. There have been many attempts to “deodorize” footwear such as U.S. Pat. No. 5,732,485 which discloses a deodorizer for masking foot and shoe odors having a retainer with an opening, a pressure-sensitive adhesive for securing the retainer to the interior surface of a shoe and a patch comprising a carrier, fragrance and polymer, wherein the fragrance is admixed with the polymer to retard evaporation or release of fragrance from the patch during storage and the carrier carries the fragrance and polymer. However, this invention requires that the deodorizer be installed in and remain in place even when the shoe is worn. U.S. Pat. No. 4,228,549 attempts to solve the problem of footwear odor with socks or stockings of woven synthetic resin yarn in which activated charcoal is present in powder and small particles form in sufficient quantities to deodorize foot odors that may be present when the socks or stockings are worn. United States Patent Application 2002/0083535 discloses a device for deodorizing and disinfecting a shoe by means of irradiation of biocidal ultraviolet (UV) light into the shoe interior. The device includes a substantially tubular light pipe that at one end incorporates a UV lamp connected to a power source, while the opposite end of the light pipe is inserted into a shoe. The inserted end may be covered by a protective cover fabricated of a thin polymer film that is substantially transparent in the UV spectral range. The light pipe has a reflective inner surface. U.S. Pat. No. 7,047,671 discloses a disposable shoe insert that can include a deodorizer, such as a time-release fragrance, and/or odor neutralizer to help reduce or eliminate foot odor. However, none of these inventions lend themselves to an easy-to-use device for managing foot odor in footwear or a device that can be rejuvenated once its effectiveness declines. Therefore, it is an object of this invention to provide a system and method for controlling foot odor that is removable from the shoe when the shoe is worn and can be rejuvenated when effectiveness is lowered without having to add additional fragrance, deodorizer, and the like. The above objective is accomplished by providing an odor nullifier for footwear comprising: a moisture-absorbing fabric bag having a first and second fold, a vertical seam, an opening and a sealing member for sealing the opening, the fabric bag having a length and width for being received internally in a shoe; a scent carrier manufactured from a mixture consisting of 49% by weight of fine cut cellulose fiber, 49% by weight of granular vermiculite and 2% by weight of fragrant oil, the scent carrier disposed inside the fabric bag; wood shavings and dried flowers contained inside the fabric bag wherein the wood shaving are present in a quantity of at least 50% of the total weight. The invention can also include dried flowers wherein the dried flowers are present in a quantity of at least 7.5% of the total weight. The dried flowers can weigh between 0.05 and 0.15 ounces. Further, the fabric bag can weigh between 0.10 and 0.30 ounces; the scent carrier can weigh between 0.30 and 0.40 ounces; and, the wood shavings weigh between 0.60 and 0.70 ounces. The moisture regain of the fabric bag is between 7.1% and 8.5%. The fabric bag containing the scent carrier and the wood shavings weights between 1.0 and 1.6 ounces. The fabric bag can have a depth of about 1.5 inches, width of about 3.0 inches and length of about 5.0 inches so that the fabric bag, when received in the shoe, occupies at least 40% of the volume of the shoe cavity. The fabric bag fabric and the closing member can be 15.4% of the total weight; the scent carrier can be 26.9% of the total weight and the wood shavings are 50.0% of the total by weight. The scent carrier can be taken from a mixture of 20 quarts of fine cut cellulose fiber, 20 quarts of granular vermiculate and 3½ cups of fragrant oil. The invention will be more readily understood from a reading of the following specifications and by reference to the accompanying drawings forming a part thereof, wherein an example of the invention is shown and wherein: Referring to Referring to Referring to In one embodiment, the scent carrier is a blend of approximately 50% fine cut cellulose fiber and 50% granular vermiculite. It has been discovered that use of vermiculite in this blend is highly absorbent and blends well with cellulose fiber with acceptable levels of resulting dust for the working and manufacturing environment. Blends or vermiculite in higher quantities leads to undesirable levels of dust production for the working and manufacturing environment. In one embodiment, the scent carrier is 100% cut cellulose. In one embodiment, the scent carrier is approximately 49% fine cut cellulose fiber, 49% granular vermiculite, and 2% nautica premium fragrant oil. In one embodiment, the scent carrier is 48.93% fine cut cellulose fiber, 48.93% granular vermiculite, and 2.14% nautica premium fragrant oil. The nautica oil can be substituted with any desirable fragrant oil to obtain different scents. This composition results in a significantly stronger fragrance than that of the common household air freshener or even potpourri resulting in an effective odor nullifying agent. Further, since the cellulose absorbs the carrier scent, when the nullifying properties are less effective over time, the bags can be agitated (e.g., shaken, rolled between your hands, kneaded, otherwise compressed or subjected to friction), which results in more of the fragrance absorbed in the scent carrier being released, thereby rejuvenating the odor nullifying properties of the invention. The resulting composition has resulted in the useful life of the invention to exceed 6 months. The odor nullifying content can be mixing in volume and subsequently divided and placed in individual bags. In one embodiment, the volume composition of the nullifying content includes 20 quarts of fine cut cellulose fiber, 20 quarts of granular vermiculite, and 3½ cups of nautica premium fragrant oil or a substituted fragrant oil. In one embodiment, the invention comprises the following components by weight: between 12.3% and 18.5% bag fabric and closing member; 21.5% and 32.3% scent carrier; 40.0% and 60.0% wood shavings and 6.2% and 9.2% dried flower. The bag fabric can be a moisture-absorbing fabric for absorbing moisture from the interior of a shoe when the bag in placed in the shoe. In one embodiment, the moisture regain is between 7.1% and 8.5%. In one embodiment, the invention comprises the following components by weight: 15.4% bag fabric and closing member; 26.9% scent carrier; 50.0% wood shavings; and 7.7% dried flowers. In one embodiment, the invention consists of 0.20 ounces of the fabric bag, 0.35 ounces of scent carrier, 0.65 ounces of cedar wood shavings, 0.10 ounces of dried flowers for a total weight of 1.30 ounces per bag. The bag can be of any fabric and can include designs such as a sport theme, flowers or any combination of designs as is common on fabrics. In one embodiment, the dried flowers can be eliminated and replaced with cedar wood shavings for 0.75 ounces. The closure member can be a ribbon of approximately 8 inches in length and ⅜ inches in width and can be double-sided satin. It is important to note that the content mixture can vary by 33% or more so that precise measurements are not necessary for the invention to provide its utility. For example, scent carrier can be measured at 2 tablespoons, and the cedar wood shavings can be measured by two level cups. This would result in variations in the actual weight of the ingredients. Typically, a shoe has a larger cross-section at the shoe opening than at the toe section. This is generally due to the shoe being designed to contour the shape and physiology of the human foot. The use of a fabric bag allows the bag to have a larger diameter at the shoe opening when inserted into the shoe and to compress due to the reduced cross-section of the shoe as the bag is received into the shoe. Referring to While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. |
