Abstract

PURPOSE: To provide an insole with superior sweat absorptivity, made at a low cost and is disposable, by composing the insole with a polymer absorptive body and nonwoven fabric placed on both upper and lower sides. CONSTITUTION: A polymer absorptive body 12 retained by paper layers 16 and 18 on top and bottom faces is surrounded by an upper and lower pair of nonwoven fabric 14 with a shape slightly larger than that of the absorptive body 12. On the edge part of the absorptive body 12 protruding from the shape of the absorptive body, a thermosensitive or pressure-sensitive adhesive 22 is applied. The edge part of the nonwoven fabric is adhered by heating or pressurizing the adhesive 22, the nonwoven fabric 14 thoroughly surrounds the polymer absorptive body 12. A fixing means 24 comprising a pressure sensitive adhesive double coated tape, etc., is equipped on the lower side nonwoven fabric 14 so as to fix this insole 10 on the sole. Thus, the polymer absorptive body 12 as the core part absorbs sweat and the nonwoven fabric surrounding the same retains the shape of the insole. It is also possible to impregnate a deodorant, an antibacterial agent or preferable fragrance into the polymer absorptive body.

Description

[Detailed description of the invention] Skin millet ■ 1l JiL standing The present invention relates to a shoe insole.

Conventional ■ Limb strain Until now, shoe insoles have been used for purposes such as moisture absorption, heat retention, and deodorization, and are made of, for example, rubber containing activated carbon, fabric, or plastic fibers woven into a double structure. Ta.

Most conventional shoe insoles are of the type that are placed over the entire sole of the shoe to prevent the insole from moving inside the shoe along with the toes when the shoe is put on and taken off. A lot of consideration has been given to the top and structure. However, conventional insoles have poor sweat absorption due to the material they are made of, are not easy to process, do not have a good appearance due to the material and structure, and are too expensive to be used as disposable items. However, the deodorizing effect could not be expected to be sufficient. The present invention solves this problem.

- In order to solve the above-mentioned problems, the core of the shoe insole is made of a polymeric absorbent material, and the upper and lower surfaces of this are covered with a non-woven fabric to form a disposable shoe insole. This is what I did.

(2) According to the insole of the present invention, the polymeric absorber as the core absorbs sweat, and the nonwoven fabric surrounding it maintains the shape of the insole. In addition to deodorants and antibacterial agents, the polymer absorbent material can also be impregnated with fragrances if desired. Since the material is only a polymer absorbent material such as a paper valve and nonwoven fabric, it is inexpensive and can be used as a disposable item.

Back markings FIG. 1 is a plan view of the insole of a shoe according to the present invention, and FIG. 2 is a sectional view taken along the line ■-■ in FIG.

As can be seen from these figures, the insole 10 of the shoe consists of a polymeric absorbent 12 and a nonwoven fabric 14 surrounding it.

The polymer absorbent material 12 is made of a material having a property of absorbing moisture such as sweat, which is used for example in sanitary napkins.
These polymeric absorbents 12 are made of 5III thick paper pipe, absorbent cotton, etc. 2 These polymer absorbers 12 are molded into a shape that follows the inside of the shoe. Considering that the insole has a small part, an insole without a bow part as shown in FIG. 4 may be used. The insole having such a shape is particularly suitable for people who do not want the insole 10 to be visible when they take off their shoes. Of course, the shape and thickness themselves are not limited at all.

On the upper and lower surfaces of the polymer absorbent body 12, thin sheets 16 and 18 with high absorbency, such as those used as toilet paper, are arranged. These edges 16 and 18 have substantially the same shape as the absorbent body 12, or have a slightly smaller shape (see FIG. 2 or FIG. 5). Polymer absorbent body 12 and these paper layers 16.18
As shown in FIGS. 5 and 6, the paper layer 16.18
A pressing portion 20 is formed by applying a pressing force, preferably in a knurled manner, to the upper and lower surfaces of the two, and the pressing portions 20 are temporarily fixed and integrated with each other.

The number, length, etc. of the pressing portions 20 can be appropriately determined depending on the pressing device or the like. These shields 16 and 18 have a function of improving the work when surrounding the polymer absorbent body 12 with the nonwoven fabric 14, but are not necessarily essential.

The polymer absorbent body 12, which is preferably held on its upper and lower surfaces with a layer of N16.18, is surrounded by a pair of upper and lower nonwoven fabrics 14, 14 each having a slightly larger shape than the absorbent body 12. Preferably, a heat-sensitive or pressure-sensitive adhesive 22 is applied to the edges of the nonwoven fabric that protrude from the shape of the absorbent body 12, and the edges of the nonwoven fabric are bonded by heating or pressurizing this adhesive 22. In this way, the nonwoven fabric 14 becomes the polymer absorbent material 12.
is completely surrounded.

By applying deodorizing and antibacterial finishing to the polymeric absorbent material or nonwoven fabric, the effect of preventing athlete's foot and the like can be obtained. Furthermore, fragrances can also be added.

In order to fix the insole 10 to the sole of the shoe, the lower nonwoven fabric 14 is provided with a fixing means 24 made of, for example, double-sided adhesive tape as shown in FIG. 3 or 4.

When using the insole of the present invention, it is only necessary to fix the insole IO to the sole of the shoe using the fixing means 24, and if it gets dirty, the insole 10 can be peeled off from the sole. Replace. It is a so-called disposable item.

As is obvious to those skilled in the art, the nonwoven fabric does not need to be formed by joining a pair of upper and lower separate members to each other, and may instead be of a type in which the absorbent body is sandwiched between folded integral nonwoven fabrics. In addition, absorber 1
2 integrally has paper layers 16.1B on the top and bottom, so
Its handling is easy.

Since the insole of the present invention has good absorbency for sweat, etc., is easy to process, lightweight, has a clean appearance, is inexpensive, and is disposable. It is also possible to prevent athlete's foot through deodorizing and antibacterial processing, and fragrances can also be added. In addition, it is surrounded by a polymer absorbent material and partially pressurized non-woven fabric, which provides solid stability throughout. Furthermore, by coloring the non-woven fabric, it is possible to prevent others from noticing the presence of the insole, and by using double-sided tape, etc., it is stable to the sole of the shoe.
