TWM601543U - Foot pad for shoes. - Google Patents

Abstract

Foot odor has always been a problem that plagues many people. There are various deodorizing ideas on the market. Common products that inhibit foot odor include deodorizing insoles and deodorizing functional socks. However, whether it is advertised How to deodorize insoles, or socks that do not need to be washed for a few days, bacteria will start to grow after its effectiveness disappears, and its residual substances will continue to accumulate in the shoes, so it will start when a certain level of concentration is reached In view of this, this patent conceives an economical and affordable product that can be replaced anytime and anywhere in order to make up for the shortcomings of the above-mentioned products. Therefore, it designs an insole that can be attached to various shoes. The sweat-absorbent pads on sandals or slippers can be replaced immediately if you want to replace them with new ones.

Description

Sweat pads for shoes

Foot odor has always been a problem that bothers many people, especially after going out early in the morning, there is almost no time to take off their shoes to breathe air, coupled with the hot and humid socks inside the shoes, it is a hotbed for rapid growth of bacteria. It is reported. The average human foot has 620 sweat glands per square centimeter. The average adult’s feet are estimated to have more than 250,000 sweat glands, and the amount of sweat secreted every day can reach several milliliters or even tens of milliliters. Although sweat has no smell, it takes a long time. The air is not able to circulate effectively in the airtight shoes, which causes the lactic acid, lipoprotein and urea in the sweat to accelerate the decomposition and decomposition, and the residual substances keep accumulating in the shoes, so as long as the concentration reaches a certain level, it will start Produce a disturbing smell.

Therefore, in order to solve the problem of foot odor, various ideas or inventions have emerged on the market. At present, the common ways to suppress foot odor are: deodorizing insoles, deodorizing functional socks, deodorizing spray and prickly heat powder, etc. Among them, the design and application of deodorizing functional socks and deodorizing insoles are the most inked. However, whether it is an insole that advertises how to deodorize or a socks that can be washed for a few days, bacteria will start to grow after the effect disappears. Moreover, when the residual material accumulates to a certain extent, it will still produce odor. Therefore, this patent turns to thinking about sticking a multi-layered sweat-absorbing material pad on the insole. After a period of use, if the odor begins to appear, it can be removed and replaced. The chemical substances such as lactic acid, lipoprotein and urea accumulated on the sweat-absorbent pad can be removed immediately.

There are conventional deodorizing insoles that add grooves or grooves to the structure of the insole. The main purpose of the insole is to let sweat flow through the grooves, or to add antibacterial and deodorizing powder in the grooves. There are other ways to do it. In the process of forming the insole, let the negative ion material be integrated into it, or the application of Chinese medicine material in the insole interlayer to prevent bacteria or deodorize, and the above products or ideas are very unique, but the world With the passage of time, most of the above substances will gradually reduce their effectiveness until they disappear. Therefore, even the most powerful or top-notch products cannot escape this rule.

In view of this, the idea of this patent comes from the fact that since the product has a lifespan, why not conceive an economical product that can be replaced anytime and anywhere, so as to make up for the above-mentioned shortcomings of the product, so it designs a product that can be attached to each product. The insoles, sandals, or sweat-absorbent pads on slippers of similar shoes can be removed and replaced as soon as they want to replace the sweat-absorbent pads with new ones, which are collectively referred to as the sweat-absorbent pads 14 for shoes in this creation.

The shoe sweat pad 14 is somewhat similar to the layering concept of a mask, that is, the conventional contact layer, the middle layer, and the outermost layer. The contact layer needs to be in contact with the foot, so the skin-friendly material is selected so as to be able to Reduce friction, and the middle layer is the main absorbent layer, its function is to absorb, inhibit bacteria, and deodorize, the outermost layer is the adhesive layer 21, its function is to stick the entire shoe sweat-absorbent pad 14 on the parts required by the insole 10 In addition, if there are other application requirements, additional materials can be added between each layer for the application of more detailed layers, and finally all the edges of the layers can be hot pressed, glued, or It is sealed by high frequency and other methods.

Since the last of each shoe style is different, each user has a different The needs of the product are not the same, so if you want to achieve the cost pressure of tearing and sticking, and reducing the cost of molds of various product sizes, you can make a single size and cut-size sweat-absorbent pad, and this sweat-absorbent pad can be cut by cutting The trimming line 13 is trimmed to the required size and then pasted for use. This is referred to as a tailorable full-foot shoe sweat-absorbent pad 11. This will help reduce the cost of different molds during production, but this specification is used There are also relatively many materials, so if you want to save material costs, you can develop products with corresponding symptoms based on sweating conditions. However, if you don’t consider material costs, you can also make various full-foot or half-foot sizes. The sweat-absorbent pad.

Generally speaking, the most prone part of the feet to accumulate a lot of sweat is in the forefoot. If the forefoot is too wet for a long time, it will easily cause the skin's protective power to decrease. Therefore, there is a high probability that mold or bacteria will invade and tighten. Then there may be symptoms such as Hong Kong foot or palmar plantar beetle. The most common parts of Hong Kong foot are different from each other, but it is common in areas such as the interdigital and forefoot metatarsals, so it is targeted at this sweating area , You can develop a sweat-absorbent pad 12 for half-foot shoes that can be tailored. In addition, metatarsal disease often occurs in the forefoot metatarsal area. The symptom is that the stratum corneum on the skin surface will be dissolved, which will cause many small pits and produce Because of the unpleasant odor, the sweat-absorbent pad 14 for shoes that only has the forefoot metatarsal area is designed for this symptom.

Figure 2 is a schematic diagram of the sweat-absorbent pad and the interior of this creative shoe.

Please refer to Figure 1 and Figure 2. The sweat-absorbent pads can be divided into cut-out full-foot sweat-absorbent pads 11, cut-out half-foot sweat-absorbent pads 12, and shoes sweat-absorbent pads 14 The basic design methods of the above three sweat-absorbent pads are divided into eight-layer structure. The layering can be added or reduced according to different needs, or the placement position can be changed. The structure of this sweat-absorbent pad is designed as: The first layer is the foot contact layer 15, which must be a skin-friendly cotton soft surface layer and has the properties of water absorption and non-recurrence; the second layer is the antibacterial and deodorizing layer 16, which functions to inhibit the number of bacteria and eliminate odor; The layer is a water-locking coating layer 17, whose function is to further lock water; the fourth layer is a polymer absorption layer 18, which functions to absorb water at a high rate; the fifth layer is a strong water-absorbing layer 19, whose effect is strong absorption Remaining moisture; the sixth layer is the breathable and waterproof layer 20, its function is to use the vent holes to exhaust heat, so that it is not stuffy; the seventh layer is the release adhesive layer 21, its role is to make it can be attached to insoles, sandals, or Slippers; the eighth layer of release paper 22, its role is to protect the viscosity of the upper layer.

In addition to the sweat-absorbent pad 14 for shoes and other fixed-size sweat-absorbent pads developed during use, the other two cut-out models can be tailored according to the needs of different shoe models. After confirming the size is correct, then Tear off the bottom release paper 22, and stick it on the required parts of various insoles, sandals, or slippers.
