Description

The present invention relates to a foot cover that is hidden inside shoes such as pumps (mainly women's shoes with a wide open instep) when worn, and is particularly easy to wear and can be removed by walking or other movements. The present invention relates to a foot cover that is also preferable for a person who has little resistance to a specific chemical substance (represented by a silicone resin described in detail later) with little misalignment.

Wearing shoes such as pumps on bare feet has become a well-established fashion. In this case, if the pumps and the sole of the foot are in direct contact with each other, the sweat generated on the foot causes the inside of the shoe to become stuffy, which causes discomfort.
Therefore, we propose a thin foot cover that covers the toes and the sole including the heel and exposes the instep and ankle, and the opening is greatly cut so that it will not be exposed from the pumps when worn. Has been done. If you wear this foot cover and wear pumps, it looks like you are wearing pumps on your bare feet, and because the foot cover is between the sole and the pumps, sweat makes the inside of your shoes stuffy. It is possible to prevent it from happening.

In addition, although such a foot attachment is described as a foot cover in this specification, it may be described as a sock cover, an inner sock, a nude sock, a cover sock, or the like.
Since such a foot cover has a large cut so that it is not exposed from the pumps, the wearing position may shift or come off due to friction during walking or the like. On the other hand, if the opening is made smaller, it will be exposed from the pumps. A foot cover developed in view of such a problem is disclosed in the following prior art documents.

Japanese Patent Application Laid-Open No. 10-292206 (Patent Document 1) states that the foot cover may come off from bare feet due to friction between the pumps and the foot cover during walking, or the foot cover may come off when the pumps are put on or taken off. In order to prevent the foot cover from being displaced, a foot cover having a friction imparting body attached to the inner surface of the heel contact portion is disclosed.
In Utility Model Registration No. 3165733 (Patent Document 2), if a rubber cord is provided along the peripheral edge of the opening of the foot cover disclosed in Patent Document 1, the rubber cord bites into the foot, so that the rubber is attached to the foot. In view of the problems that the string is attached, it feels painful, and it is not comfortable to wear, a flat rubber is provided along the periphery of the opening so that one side is in contact with the foot. The foot cover forming the portion is disclosed.

Japanese Unexamined Patent Publication No. 10-292206 Utility Model Registration No. 3165733

Here, the friction-imparting body of the foot cover disclosed in Patent Document 1 may not be sufficient. In this case, the foot cover may come off or the wearing position may be displaced when walking or taking off and putting on the pumps. Relax. In the flat rubber disclosed in Patent Document 2, since the flat rubber is provided over the entire peripheral edge of the opening (depending on the elasticity of the flat rubber), the opening is sufficiently opened when the foot cover is worn. In addition to the fact that it may be difficult to put on the foot cover without opening it, there is also a problem that the foot cover may come off or the wearing position may shift when the pumps are put on and taken off, as in the case of the foot cover disclosed in Patent Document 1.

Further, a silicone resin, which is a specific chemical substance, is often preferably used as the friction imparting body, and the foot cover is formed by directly adhering the skin of the foot and the silicone resin by using the adhesive property of the silicone itself. Solves the problem that the silicone is removed or the wearing position is misaligned.
However, while silicone resins are suitable for solving such problems, they are less resistant to certain chemicals, silicone resins (because such foot covers are worn on bare feet) (the skin of the feet is specific). The skin of the foot that adheres to the silicone resin may be fogged (disappeared) by the silicone resin, which is a chemical substance, or the silicone resin does not have breathability due to reasons such as (weak against chemical substances). Therefore, there is a possibility that you may get stuffy and irritated by your own sweat that sweats from the feet that adhere to the silicone resin.

The present invention has been developed in view of the above-mentioned problems of the prior art, and an object of the present invention is that the foot cover may come off or the wearing position may shift when walking or taking off and putting on the pumps. It is an object of the present invention to provide a foot cover capable of suppressing a foot skin irritation caused by a silicone resin without causing a rash.

In order to achieve the above object, the foot cover according to the present invention takes the following technical measures.
That is, the foot cover according to the present invention is a foot cover that covers the toes and the sole including the heel and exposes the instep and ankle, and is knitted with elastic fabric, such as the sole, the side surface, and the foot cover. An opening formed by the heel and the toe covering the toe is provided on the opposite side of the sole with respect to the sole, and the side and the heel along the peripheral edge of the opening. A strip-shaped non-slip portion having elasticity and adhesiveness is provided on at least one of the portions, and the non-slip portion is formed of a styrene-based thermoplastic elastomer.

Preferably, the non-slip portion can be configured to be formed of a mesh sheet of a styrene-based thermoplastic elastomer.

According to the foot cover of the present invention, the foot cover does not come off or the wearing position does not shift when walking or taking off and putting on the pumps, and it is possible to suppress skin irritation of the foot due to the silicone resin. A foot cover can be provided.

It is an overall perspective view of the foot cover 100 which concerns on 1st Embodiment of this invention. It is a perspective view which turned over the foot cover 100 of FIG. It is an overall perspective view of the foot cover 200 which concerns on the 2nd Embodiment of this invention. It is a perspective view which turned over the foot cover 200 of FIG.

Hereinafter, the foot cover according to the embodiment of the present invention will be described in detail with reference to the drawings. There are various structures of the foot cover, and the present invention is not limited to a specific structure, and any structure of the foot cover can be used as long as it has the features described later. Basically, it does not matter what kind of fabric is used to form the foot cover, the pattern of the fabric and the method of joining the fabric. Therefore, the structure of the foot cover shown below is merely an example.

In addition, the fabric that forms this foot cover is knitted using bare heaven (bare heaven: a thread (covered yarn, etc.) wound with threads of other materials (cotton, wool, etc.) around a polyurethane thread. Flat knitted fabric), tricot (warp knitted fabric knitted by a tricot machine which is a kind of warp knitting machine), fabric for pantyhose (knitted fabric containing polyurethane yarn and nylon yarn) and the like are preferably used. In particular, among these, bare heaven has (1) excellent elasticity, (2) good shape stability and little shape change after washing, and (3) soft texture and excellent fit. , (4) It is hard to wrinkle and crease, (5) It has a porous structure, so it is breathable, and (6) When it contains cotton, it has good touch and hygroscopicity, which is preferable for a foot cover. In the following, the fabric and the knitted fabric may not be distinguished.

Further, the foot cover according to the present embodiment is a foot cover that covers the toes and the sole including the heel and exposes the instep and the ankle, and covers the sole, the side surface, the heel, and the toe. It is formed at the tip of the toe. Further, although not limited, the foot covers shown below are shared on the left and right sides, and are preferable in that the left and right sides are not mistakenly worn because they are shared on the left and right sides. If the foot cover is not shared on the left and right sides, the left foot cover and the right foot cover have symmetrical shapes.

And what is characteristic is that at least one of the side and heel along the periphery of the opening for putting in and out of the foot is provided with a strip-shaped non-slip portion having elasticity and adhesiveness. This is a point where the non-slip portion is formed of a mesh-like sheet of styrene-based thermoplastic elastomer. The foot cover according to the present embodiment is composed of a plurality of fabrics (a fabric forming the toe portion 102, a fabric forming the sole portion 104, and a fabric forming the side side portion 106 and the heel portion 108). It may be composed of a plurality of fabrics other than these), but the joining of these fabrics is not limited. For example, the fabrics may be joined to each other by stitching, or by heating with an adhesive tape having an adhesive coated on one surface of the strip-shaped member, the adhesive melts and the fabrics are heat-bonded to the fabrics. It does not matter if they are joined together. Here, this joining includes those by thermocompression bonding, those by heat welding, those by heat welding, and the like.

<First Embodiment>
Hereinafter, the foot cover 100 according to the first embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.
1 and 2 show the foot cover 100 according to the embodiment of the present invention. FIG. 1 is an overall perspective view of the foot cover 100, and FIG. 2 is a perspective view of the foot cover 100 turned inside out. In each of the views, it is assumed that the foot cover is worn on the wearer's foot F. ing. That is, since the foot cover according to the embodiment of the present invention is made of an elastic fabric such as pantyhose, it will be in a shrunk state if it is not shown in this assumption, and the shape should be understood. Is difficult, so it is assumed as described above.

The foot cover 100 is a foot cover that covers the toes of the wearer's foot F and the sole including the heel, and exposes the instep and ankle. The foot cover 100 is made of a thin elastic fabric having a large opening, which is a opening, so as not to be exposed from the pumps when worn.
The foot cover 100 is formed of a toe portion 102, a sole portion 104, a side side portion 106, and a heel portion 108. An opening for putting the foot in and out is provided on the opposite side of the sole 104. The opening will be formed in the upper part of the toe part 102, the upper part of the side side part 106, and the upper part of the heel part 108.

In this foot cover 100, for example, the toe portion 102, the sole portion 104, the side side portion 106, and the heel portion 108 are separately knitted (the side side portion 106 and the heel portion 108 are integrally knitted), and the side side portion 106 is formed. And the heel portion 108 and the toe portion 102 are sewn and integrated, and further, these integrated toe portion 102, the side side portion 106 and the heel portion 108 and the sole portion 104 are sewn and integrated. ing. The non-slip tape 116 (which is a non-slip portion and is formed by cutting a mesh-like sheet of styrene-based thermoplastic elastomer into a tape shape) is a foot before sewing (that is, before being integrated). It does not matter whether it is adhered to the fabric of the cover 100 or after being sewn (that is, after being integrated) to the fabric of the foot cover 100. Further, in the method of cutting the mesh-like sheet of the styrene-based thermoplastic elastomer provided as the non-slip tape 116 into a strip shape and then providing the mesh-like sheet on the knitted fabric of the foot cover 100, the elastomer is thermally bonded by utilizing the fact that the elastomer is thermoplastic. It is preferable to attach it to the cloth, but other methods may be used.

Here, as such a styrene-based thermoplastic elastomer, an elastic member having biocompatibility, elasticity (flexibility) and adhesiveness is used, and a thermoplastic elastomer such as a styrene-based elastomer is preferably used. .. In this embodiment, a polystyrene-based elastomer Arneston (registered trademark) was used.
In the foot cover 100, openings for putting in and out the foot, which are provided on the opposite sides of the sole 104, are formed by the toe 102, the side 106, and the heel 108. Then, on at least one of the side side portion 106 and the heel portion 108 along the peripheral edge of the opening (in the foot cover 100, both the side side portion 106 and the heel portion 108, and all of the side side portions 106 and All of the heel portion 108), a strip-shaped non-slip tape 116 (formed by cutting a mesh-like sheet of a styrene-based thermoplastic elastomer into a tape shape) having elasticity and adhesiveness are provided. In addition, in this foot cover 100, the toe portion 102 along the peripheral edge of the opening (about 5 mm to 15 mm having appropriate elasticity to prevent the foot cover 100 from coming off or shifting from the foot F). The stretchable narrow fabric 112 is provided (for example, thermally adhered to the skin contact side of the fabric with a thermoplastic adhesive), but in place of / in addition to this, a strip-shaped slip having elasticity and adhesiveness. A stop tape (formed by a mesh sheet of a styrene-based thermoplastic elastomer) may be provided. In some cases, a non-slip tape (formed by a mesh-like sheet of a styrene-based thermoplastic elastomer) may not be provided on either the side side portion 106 or the heel portion 108 along the peripheral edge of the opening. That is, in the foot cover according to the present invention, it is sufficient that at least one of the side side portion 106 and the heel portion 108 along the peripheral edge of the opening is provided with the non-slip tape 116 having elasticity and adhesiveness. Absent.

Since the non-slip tape 116 formed of the mesh-like sheet of the styrene-based thermoplastic elastomer having elasticity and adhesiveness is provided in the opening, the adhesion between the foot F and the foot cover is improved and the foot cover 100 is provided. Can be prevented from coming off or slipping off the foot F.
Further, in the sole portion 104, on the side opposite to the side in contact with the foot F (the side in contact with the inner sole of the pumps when the pumps are worn), a non-slip sole portion formed of a mesh-like sheet of styrene-based thermoplastic elastomer is provided. It is also preferable to provide it. As a result, it is possible to improve the adhesion with the inner bottom of the pump and prevent the position of the foot cover 100 in the pump from being displaced.

It is also preferable to provide the sole portion 104 with a cushion portion having better elasticity than the other portions forming the foot cover 100 by using a styrene-based thermoplastic elastomer.
The non-slip tape 116 of the foot cover 100 having such a feature will be described in more detail.
The non-slip tape 116 is obtained by cutting a mesh-like sheet of styrene-based thermoplastic elastomer into a narrow tape (about 5 mm to 15 mm) and heat-adhering it to a knitted fabric forming a foot cover 100 by utilizing the thermoplasticity. It is (pasted). The method of providing the non-slip tape 116 on the knitted fabric of the foot cover 100 is a method other than the method utilizing such thermoplasticity (adhesion using an adhesive, a method other than adhesion, etc.), for example, the following. The method shown may be used.

As described above, in the foot cover 100 according to the present embodiment, the non-slip tape 116 having elasticity and adhesiveness is provided on the side side portion 106 and the heel portion 108 along the peripheral edge of the opening. Although described as, it may be a strip-shaped or continuous point-shaped styrene-based thermoplastic elastomer instead of tape, and may not be adhesive. That is, instead of heat-bonding a mesh-like sheet cut into a narrow tape (about 5 mm to 15 mm) to the knitted fabric as the non-slip tape 116, for example, the elastomer is a rotary type as a non-slip portion. It may be adhered in a band shape or a continuous dot shape by a machine like silk printing. Further, instead of silk printing by such a rotary type machine, the elastomer may be provided in a band shape or a continuous point shape on the peripheral edge of the opening by a jet type machine.

The non-slip tape 116 in the foot cover 100 is a mesh sheet of a styrene-based thermoplastic elastomer cut into a narrow tape shape (about 5 mm to 15 mm), and is (1) a styrene-based thermoplastic elastomer. In addition, it is possible to suppress the irritation of the skin of the foot due to the silicone resin, and (2) it is possible to suppress the irritation caused by the sweat of oneself sweating from the foot due to the mesh shape.

Further, since the non-slip tape 116 in the foot cover 100 has (3) elasticity, the opening can be greatly opened when the foot cover 100 is put on and taken off, and the opening is opened after the foot cover 100 is put on. It is possible to prevent the foot cover 100 from shrinking and coming off or slipping off from the foot F, and (4) preventing the foot cover 100 from coming off or slipping off from the foot F after being worn for adhesiveness. It can be suppressed.

Further, since the non-slip tape 116 in the foot cover 100 is (5) a thermoplastic elastomer, it can be easily heat-bonded to the fabric, so that the manufacturing cost can be suppressed.
As described above, according to the foot cover according to the present embodiment, the opening of the foot cover is not provided with rubber (Patent Document 1) and flat rubber (Patent Document 2), and the side along the peripheral edge of the opening. A strip-shaped non-slip tape 116 (a mesh sheet of a styrene-based thermoplastic elastomer is cut into a narrow tape (about 5 mm to 15 mm) on at least one of the side portion 106 and the heel portion 108) having elasticity and adhesiveness. (Formed by what was done) was provided. For this reason, it is not necessary to provide rubber or flat rubber in the opening and a non-slip material separate from the flat rubber in the heel, and it is not necessary to impair the comfort of wearing, and when walking and putting on and taking off the pumps. It is possible to prevent the foot cover from being removed or the wearing position from being displaced at times, while suppressing the skin irritation of the foot due to the silicone resin.
