BACKGROUND OF THE INVENTION

This invention solves at least the following two problems: (1) Most athletic sneakers have very rare and exclusive “insoles” that only come in the foot ware when you buy the sneakers. Once the insoles are dirty, and stinky they cannot be replaced with the same insole because Shoe/Sneaker brands/manufacturer typically do not sell the insoles separately. Having used, dirty insoles deplete the value of the sneaker and for sneaker traders and resellers this is a significant problem. This invention preserves the original insole that comes in the sneakers and protects it from dirt, bacteria, sweat, odors, viruses etc . . . ; and (2) A Logo on the insole that identifies the brand or style gets worn off after so many wearings. This also depletes the value of the foot-ware and ruins the insole or at least limit this unwanted absorption.

SUMMARY OF THE INVENTION

A system and method and apparatus comprising an anti-microbial, self-adhesive film, are provided which prevents dirt, sweat, fungus, and bacteria from absorbing into the insole and the sides and bottoms of the insole. The antimicrobial, self-adhesive film of the invention is provided in a size suitable for application to an insole so as to prevent dirt, sweat, bacteria, foot wort fungus etc. from absorbing into an insole, through its sides, top and bottom surfaces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is not intended to limit the scope of the invention in any way as it is exemplary in nature, serving to describe the best mode of the invention known to the inventors as of the filing date hereof. Consequently, changes may be made in the arrangement and/or function of any of the elements described in the exemplary embodiments disclosed herein without departing from the spirit and scope of the invention.

Most shoes come with insoles and most insoles are made from a soft absorbent material. Especially rare and expensive footwear like “NIKE”™, “YEEZY”™, etc. come with their own branded insoles that are not replaceable unless you buy another pair of the same sneakers. Some of these sneakers can cost up to $10,000 USD, so they can be very expensive. When the insole absorbs sweat, bacteria, dirt and other elements, it causes your shoes to hold germs, look used and dirty and worst of all, stink.

The original equipment manufacturer (OEM) insoles that come in all “NIKE”™, “JORDAN”™'s and “YEEZYS”™ exclusive footwear for example, are not produced for separate sale. Consequently, you can't replace the insoles once they are dirty and looking worn out and old. This devalues the sneaker or footwear.

The invention offers the ability to protect the insole so as to:

1. preserve a logo on the insole from rubbing off from wearing your shoes;

2. keep your insoles looking new and germ free; and

3. preserve them while being worn, all while keeping them on an essentially germ-free anti-microbial path thus maintaining healthy shoes (and therefore also feet) for months and years to come.

Referring now to FIG. 1, an exemplary embodiment of an exclusive “NIKE”™ sneaker 10 with an insole 12 that cannot be re purchased is shown. It's a must to keep the insoles clean and looking new because, practically speaking, one cannot replace the insoles. The various insoles 12 that come in footwear essentially all include important identifying logos 14, typically on the heel area or in their center area. These logos 14 help identify the brand and often are critical in determining whether the footwear is authentic. If these logos can be maintained as good as new, this solves a huge problem and helps preserve the irreplaceable and valuable insole.

Referring now to FIGS. 2A and 2B, show a comparison of one shoe 16 with the film 18 of the invention (FIG. 2A) and one shoe 20 without (FIG. 2B). These insoles are both white and have the same exact black Logo 14 on them. It is apparent from the figure that the logo on the bottom sneaker 20 has been rubbed off and it is very dirty. In contrast, the top sneaker 16 still has the brand name 14 and is being preserved and protected. Such logos and brand names 14 identified on these insoles 12′ are very important, but unfortunately start to wear off after just several wears and eventually completely fade away, if not protected by the present invention.

Referring now to FIG. 3, the film 18 of the invention is made up of a plastic layer 25 to which an adhesive backing layer 24 is applied, optionally with special treatment of the plastic layer 25 to promote adhesion.

Referring now to FIG. 4, an insole 12″ is shown where the upper portion 12a did not benefit from the protective film 18 (shown in FIG. 5) of the invention and the lower portion 12b did. In this view, the protective film 18 is removed to show the contrast. Clearly, the upper portion 12a of the insole is soiled, and the lower portion 12b is clean, as new.

Referring now to FIG. 5, the result of an experiment is illustrated. In an experiment, the thin anti-microbial adhesive film combination 18 was wrapped around only to a part of the insole 12. Only after one week of wearing the shoes, one can already see how much dirt and germs (see area 12b) it's protecting the insole 12 from absorbing. The thin, anti-microbial adhesive film 18 wraps insoles 12 to preserve them and protect them from the elements listed above and provide a safer, healthier environment for both the wearer's foot and the footwear. They are user friendly and easy to install. These will especially be appreciated by consumers who share, sell, trade sneakers/shoes.

The device 18 according to the invention is made from a special plastic film that is extremely strong, stretchy, durable and made with an anti-microbial material.

In one embodiment, one side 22 (the interior side 22 directed towards the insole 12 when installed on the insole) incorporates an adhesive to enable the film to stick to and therefore cover and protect insoles. The adhesive 24 is a fixation means that provides as the effect that the plastic layer 25 does not dislodge or move out of place while the sneaker/shoe is being used. The other side 26 (the side directed towards the wearer's foot when worn) of the device 18 may be smooth, textured (for “non slip”/stop from sliding in the shoe), or slotted or perforated (to permit breathing/air flow).

Referring now to FIGS. 6A and 6B, schematic top views of the invention are shown. For example, an insole 402 is shown. In FIG. 6A, for example, two different sizes of insoles 402a, 402b are shown in order to visualize the applicability of the invention of a certain size to different sizes of insoles. As described above, the device according to the invention is made from a special plastic film that is extremely strong, stretchy, durable and made with an anti-microbial material. In a preferred embodiment, the outer contour of the film 404 overlaps the outer contour of the insole when placed on the insole. In another preferred embodiment, the outer contour of the films comprises flaps 406 that facilitate installation. The border area 410 along the outer contour of the film 404 can be sticky for easy application but not too sticky so as to facilitate easy removal. The sticky border area is configured to seal to the bottom of the insole when installed in order to prevent odors.

In one embodiment, the side of the film 404 directed towards the insole when installed on the insole is free of adhesive in the area where it gets in contact with the upper part of the insole, so it does not leave any sticky residue in the insole when it is removed and any logo/pattern/etc. present on the upper part of the insole will not be pulled off when the film is removed from that insole. However, in another embodiment, said area may be covered, either partially or fully, with adhesive. Exemplary, said area may be as large as the crossed area 405 in FIG. 6B. In one preferred embodiment, the film comprises extra margins 412 overlapping the outer contour of the insole, such to be securely foldable over the bottom of the insole. This embodiment further provides, optionally, cuttings 414, allowing portions of the film to overlap or to strut apart from each other when folded over the bottom of the insole. The cuttings shown in FIG. 4A are shown at preferred positions, however, they may be as well on other positions. Co-branding on the film is possible such that on one hand the logo/pattern/etc. of the insole is visible to an observer, and on the other hand a logo/pattern/etc. may be present on the film.

Pine tree rosin mixed with a polymer can be used as a natural shield against harmful microbes. See products offered by PREXELLENT (see prexellent.com). In addition, 3M™ Durable Protective Film 7750AM using a semi-permanent adhesive (Part Number 7750AM, 3M Product Number 7750AM, 3M ID 70000244056) may also be used. The protective film is typically 2 mil thick with an adhesive for semi-permanent applications includes antimicrobial additive. The film is optionally transparent with a hard-coat layer that resists scratches, abrasion and chemicals. It is also resistant to various common cleaning products such as bleach, isopropanol and hydrogen peroxide. The PET film provides robust protection with high clarity. It uses 3M™ Adhesive 400: good wet-out and clarity, non-yellowing when exposed to UV light. It includes an EPA-registered antimicrobial agent*. The EPA-registered silver ion antimicrobial additive* helps the hard-coat resist the growth of microbes, odour-causing bacteria, mould and mildew between cleanings. The silver ion antimicrobial agent that protects the film is integrated into the structure of the hard-coating and will reasonably last the lifetime of the coating. This product uses 3M™ Adhesive 400, which offers good wet-out and clarity and is non-yellowing when exposed to UV light; it is intended for permanent to semi-permanent applications. The hard-coat provides protection against scratches, abrasion and cleaning chemicals for surfaces in high-touch environments and, in addition, inhibits most bacteria, mould and mildew on the hard-coat between cleanings. Note that full protection against microbes and pathogens is impossible. Therefore, the user must take additional measures to better ensure their safety against contagious viruses such as COVID-19. Note that 3M™ Durable Protective Film 7760AM is specifically made for removable applications such as required by the invention.

A suitable anti-microbial film is preferably treated in areas where an adhesive film is to be provided via an abrasion treatment, a corona light treatment, or other treatment suitable for increasing the adherence of the adhesive to the film, in order to avoid that it comes off on the insole, separating from the plastic anti-microbial film due to the abrasion caused by foot movement in the shoe. Separation causes the film to fail to protect the insole. After the adhesive film is provided, a peel-off protective tab is applied to the adhesive (such as exists with band-aids) to allow exposure of the adhesive at the time chosen by the user, just prior to applying the adhesive film to the foot, the insole, or the shoe.

Another suitable anti-microbial film can be found on: silverdefender.com. Installation is Simple. First, make sure the surface to be protected is clean and dry. Second, peel and stick. Optionally, application instructions are printed on the protective film covering the adhesive. These instructions therefore are removed from the adhesive backed sheet and so available for reference when installing the film. Optionally, the adhesive on the film is pressure sensitive. Make sure to press down thoroughly, including all the edges for optional adhesion.

The present invention is suitable for various types of footwear. From sneakers or shoes with insoles to sandals or flip flops. As is clear, one can also apply the invention to the tops of flip flops or sandals to protect and help keep the top area clean, new and preserved.

A detailed description on how the invention works is now provided. The invention is typically die-cut and may be substantially of a rectangular shape or cut to an insole shape. The film should be wider and longer than the actual “insole” so that the excess portion can be wrapped around the insole from the top of the insole then wrapping around to the bottom of the insole to optionally create an air tight fit. A user simply peels off the backing protecting the adhesive and carefully applies the adhesive side to the insole. The firm can be flattened out with the user's fingers so there are no air bubbles in it. Then wrap the excess film around the insole. For sandals or flip flops, there is optionally provided a dotted perforated line in between the big toe and pointer toe to allow for the piece of the sandal that is often disposed in between those specific toes to pass through. This feature may be pre made at the factory or the consumer may simply cut the film of the invention at the appropriate location to accommodate that piece of the sandal.

Note that it is recommended, for example, to replace the film of the invention every 90 days or after 90 wearings. However, more frequent replacement results in better protection.
