DETAILED DESCRIPTION OF THE PRESENT INVENTION
[0024] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.
[0025] As noted above, there is a long-felt need in the art for a device that can improve or reduce odors coming from footwear. There is also a long-felt need in the art for a novel device that is in the form of a shoe liner capable of absorbing sweat from the feet of a user. Additionally, there is a long-felt need in the art for a novel shoe liner that prevents footwear from becoming odorous and embarrassing to take off. Moreover, there is a long-felt need in the art for a device that can function like a shoe liner and provides a practical, convenient, and inexpensive method of keeping shoes smelling pleasant and fresh. Further, there is a long-felt need in the art for a device that eliminates use of baking soda, perfume, and more in shoes/footwear for removing odors and unpleasant smells. Furthermore, there is a long-felt need in the art for a device that can keep different types of footwear fresh and fragrant. Finally, there is a long-felt need in the art for an improved footwear liner that securely fits inside a footwear and gives off a pleasant odor from within the shoe.
[0026] The present invention, in one exemplary embodiment, is a shoe assembly that releases a pleasant fragrance throughout the day. The shoe assembly including a removable shoe liner having a top absorbing layer made of non-woven material, a bottom adhesive layer having a polyurethane adhesive, the shoe liner fits inside the shoe and substantially covers the insole of the footwear, in use the adhesive layer attaches to the insole, an essential oil(s) infusing the top layer releases fragrance when a user wears the shoe and places the foot on top of the shoe liner.
[0027] Referring initially to the drawings,
[0028] The liner device 100 is shaped to cover a substantial portion (i.e., a majority of the area) of the insole surface of a footwear and can be designed in different shapes and sizes to fit different types of footwear. The adhesive layer 104 can be made from one or more of polyurethane, neoprene, butadiene, and more. Preferably, the adhesive layer 104 is made from a castor oil-based polyurethane adhesive. The adhesive layer 104 provides a peel strength from about 1 g/25 mm to about 5 g/25 mm for effective adhesive strength.
[0029] The elastomeric layer 102 is infused with natural and skin friendly essential oil fragrances and is in a non-woven arrangement to absorb moisture and sweat from the foot of a user. The elastomeric layer 102 preferably has essential oils including a flavor or a scent of one or more of lavender, lemon, wood, mint, jasmine, rose, and many more. In the preferred embodiment, the shoe liner 100 is disposable and provides better grip and security to a user. The elastomeric layer 102 provides a coefficient of friction of about 0.4 .Math. to about 0.5 .Math. for prohibiting any slippage of foot and providing adequate gripping.
[0030] Structurally, the liner device 100 has a heel end 108 and a front end 110 extending between a longitudinal portion. The heel end 108 and the front end 110 are designed to adequately support and balance the weight of a user and preferably, the heel end 108 is 40% thicker than the remaining portion of the liner device 100. The design of the heel end 108 and the front end 110 can be designed on the basis of different types of footwear.
[0031] The liner 100 can be designed to be accommodated in different types of shoes, flip-flops, high-heels, sandals, moccasins, high boots, and more. The liner 100 can be easily peeled off from the insole of the footwear at the end of the day and can be replaced with a new liner device 100. The liner 100 is especially useful for users who like to wear their footwear without any socks or stockings as the elastomeric layer 102 effectively absorbs sweat and moisture, while simultaneously providing a fragrance. In some embodiments of the present invention, the elastomeric layer 102 may have a coating of an anti-microbial substance to kill any bacteria or microbes that may be present in the footwear.
[0032]
[0033] Preferably, the heel end 108 overlaps the heel portion 204 of the footwear 200 and the front end 110 overlaps the toe portion 206 of the footwear 200 for adequately providing support and grip to a user’s foot. The liner 100 is flexible and therefore, can be easily placed inside the footwear 200. The liner 100 can be easily placed manually inside the footwear 200 without need of any applicator device. Further, as illustrated, the liner 100 is not visible from outside when positioned inside the footwear 200 and therefore, provides an aesthetic appeal while providing a feel of a sock or stocking to a user. The liner 100 also provides protection from wear and tear to the insole 202 of the footwear when the liner 100 is repeatedly used in the footwear 200.
[0034]
[0035] The slits 301, 305, 307 and the cut-outs 302, 306, 308 are designed to accommodate the straps of the flip flop and/or sandal footwear such that the liner 300 is effectively and securely positioned on the insole of the flip flop.
[0036] The liner device 100, 300 can be designed to fit any type of footwear and is designed to mirror both the right and left foot in each of the various sizes, in order to be more convenient and easier to use. The custom sizing enables proper insertion into footwear since cutting of the device and use of an applicator is obviated. Further, the liners of different embodiments may have different styles, colors, and logos printed on the surface including, but not limited to, cartoon characters, sport team logos, Bible scriptures, and more.
[0037]
[0038] The footwear can then be worn in a conventional manner by a user, such that the fragrance from the liner is released when the liner is compressed by the weight of the user during walking, running, or even sitting (Step 408). Finally, after the footwear has been worn for a specific duration such as 8 hours, 10 hours, 12 hours, or 16 hours, the liner can be removed by pulling the adhesive layer (Step 410) away from the insole.
[0039] Certain terms are used throughout the following description and claims to refer to particular features or components.
