Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to insoles.

[0002]

[Background technology and problems to be solved by the device]

 A shoe insole having a plurality of dots formed at predetermined intervals on the surface of a main body of the insole is commercially available. In addition to the anti-slip effect, such insoles also have the effect of promoting blood circulation because the dots stimulate the soles of the feet. However, such a conventional insole is not preferable in terms of design because dots are exposed on the surface.

Therefore, as shown in FIGS. 3 and 4, conventionally, a pad 2 of natural or artificial / synthetic leather is sewn to a part of the insole 1 (the part of the heel) with a sewing machine to improve the design. Although some insoles have been proposed, such an insole 1 was time-consuming to manufacture and costly. Furthermore, since the dots 3 of the conventional insole 1 are formed only of synthetic resin such as polyvinyl chloride, although the effect of promoting blood circulation in the foot can be obtained due to the dot structure, if sweating is high, the There was a problem of peeling. Then, the peeling caused a foul odor. Therefore, an object of the present invention is to provide an insole capable of providing a good feel and appearance and also having an effect of preventing unevenness.

[Means and Actions for Solving the Problems]

 The insole according to the first aspect of the present invention is characterized in that dots are formed on the back surface side of the insole body. The surface side of the insole body may be subjected to suitable surface treatment such as anti-slip treatment. The insole according to the second aspect of the present invention is characterized in that, in the first aspect, the dots contain an antibacterial agent.

The antibacterial agents include organic antibacterial substances and inorganic antibacterial substances. Specific examples of the organic antibacterial substance include benzimidazole, triazole, dithiocarbamate, organic tin, antibiotics and the like. Specific examples of the inorganic antibacterial substances include copper agents, inorganic sulfur agents, silver salts and the like. The insole according to a third aspect of the present invention is characterized in that, in the first aspect, the dots contain a deodorant.

The deodorant includes an organic deodorant and an inorganic deodorant. The organic deodorant is classified into an aroma-releasing type and a decomposing type. The aroma-releasing type includes terpenes, esters, aldehydes and the like, and the decomposing type includes peroxides and the like. Specific examples of the inorganic deodorant are adsorption type silica gel, activated carbon, zeolite and the like.

An insole according to a fourth aspect of the present invention is characterized in that, in the first aspect, the dots contain magnet powder. The magnet has a magnetic health effect such as promoting blood circulation, and has a magnetic flux density of, for example, 50 to 1000 gauss. An insole according to a fifth aspect of the present invention is characterized in that, in the first aspect, the dots contain a sweat absorbing substance.

Specific examples of the sweat absorbing substance are collagens, chitin, silk (fibroin), wool (keratin), gelatin, cellulose and the like. The collagens include collagen, reticuline, vitrocin, ichthiochol, ichtylepidine, elastoidin, cornein, spongin and the like. Further, the dots may contain a plurality of kinds of substances selected from the above-mentioned antibacterial agent, deodorant, magnet powder and sweat absorbing substance according to a desired function.

The material of the dots is arbitrary, and for example, polyurethane, polyvinyl chloride, acrylic acid resin, latex or the like can be used. The method of dot processing is arbitrary, and for example, dots can be formed on the surface of the sheet base material by a method similar to rotary screen printing. As the base material of the sheet, artificial / synthetic leather, natural leather, synthetic resin (polyurethane, polyvinyl chloride, polyethylene, etc.), non-woven fabric, woven fabric, knitted fabric and the like can be used.

EXAMPLES Referring to Examples 1 FIGS. 1 and 2, illustrating a shoe insole according to the present embodiment with a manufacturing method thereof. First, using a dot processing device, hemispherical dots were formed by printing a coating liquid on the back surface of a synthetic leather sheet substrate to manufacture a dot processed sheet. The dot processing device has a structure similar to that of a rotary type screen printing machine, and has a plurality of holes having a diameter of about 0.5 to 3 mm for forming dots formed at predetermined intervals on the surface of a plate cylinder.

The composition of the coating liquid for forming the dots is as follows. Polyvinyl chloride 100 parts by weight Plasticizer (phthalate ester) 60 parts by weight Stabilizer (metal soap) 4 parts by weight Filler (calcium carbonate) 40 parts by weight Thinner 10 parts by weight

Next, this dot-processed sheet was cut into a shoe insole to obtain an insole 11 according to this embodiment as shown in FIGS. As shown in the figure, in the insole 11 of this shoe, dots 12 are formed on the back surface side of the insole body 13. With regard to the shoes with this insole 11, the comfort, design and cost were evaluated. The results are shown in Table 1. In the evaluation column of this table, ⊚ indicates very good, ∘ indicates good, Δ indicates normal, and x indicates bad. The comfort and design were evaluated by having 10 healthy adults wear shoes with the insole according to the present example and listening to the feel or impression.

Examples 2 to 5 2 parts by weight of an antibacterial agent, 10 parts by weight of a deodorant, 10 parts by weight of magnet powder and 20 parts by weight of a sweat absorbing substance were added to the coating liquids of Examples 1 and 2, respectively. By the same manufacturing method, the insole 11 according to each of Examples 2 to 5 was obtained. With respect to the insole 11 of each example, the comfort, design and cost were evaluated in the same manner as in Example 1. The results are shown in Table 1.

Comparative Examples 1 and 2 Insole in which dots are formed on the surface side of the insole body (Comparative Example 1) and dots are formed on the surface side of the insole body, and a part of natural leather pad is sewn on With respect to the shoes provided with the insole (Comparative Example 2, see FIG. 3), the comfort, design and cost were evaluated in the same manner as in the above Examples. The results are shown in Table 1. No antibacterial agent was added to the dots of the insole of the comparative example.

[0015]

[Table 1]

As shown in Table 1, in the insole 11 according to each example, the dots 12 are formed on the back surface side of the insole body 13, and thus it is understood that the shoes are comfortable to wear. Also, the design is good. Further, since it is not necessary to sew the pad on, it is advantageous in terms of cost.

The insoles 11 of Examples 2 to 5 in which the dots contain the antibacterial agent, deodorant, magnet powder or sweat absorbing substance have a function based on each additive component. . Even when the dots 12 are formed on the back side of the insole body 13, when the shoe is put on, there are depressions between the dots 12 on the back side on the front side, while the dots 12 on the back side are convex. As a result, a blood circulation promoting effect that is substantially the same as when the dots 12 are formed on the surface side is obtained.

On the other hand, in the case of the insole according to Comparative Example 1, some people did not like the design. In addition, in the case of the insole according to Comparative Example 1, the pad is sewn on, which is a disadvantage in terms of cost.

[0019]

[Effect of device]

 According to the insole of the present invention, the feel and the appearance can be improved. Further, the insole containing the antibacterial agent, deodorant, magnet powder or sweat absorbing substance in the dots has a function based on each additive component.
