Description

The present invention relates to a foot cover that hides inside shoes such as pumps (mainly women's shoes with a wide open instep) when worn, and in particular, at least one toe with a wide open instep. The present invention relates to a foot cover that does not easily come off or shift due to movements such as walking, even if it is an ultra-shallow foot cover that covers at least one foot cover and does not cover the base of one toe.

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 get stuffy, which causes discomfort.
Therefore, we propose a foot cover that covers the toes and the sole including the heel and exposes the instep and ankle, and a thin foot cover with a large cut so that it will not be exposed from the pumps when worn. Has been done. If you wear this foot cover and put on 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 being lost.

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 you make the opening small, it will be exposed from the pumps. A foot cover developed in view of such problems is disclosed in the following prior art documents.

Utility Model Registration No. 3165733 (Patent Document 1) discloses a foot cover that does not bite into the wearer's foot and does not cause the foot to become shaped, feel pain, or cause discomfort. This foot cover is made of a material that covers the wearer's foot and has an opening for putting the foot in and out on the upper side. A flat rubber is provided along the peripheral edge of the opening so that one side of the foot cover touches the foot. It is characterized by forming a strip-shaped stretchable portion.

Utility Model Registration No. 3165733 Gazette

However, in the flat rubber provided on the foot cover disclosed in Patent Document 1, since the flat rubber is provided over the entire peripheral edge of the opening, the opening is not sufficiently opened when the foot cover is put on. It may be difficult to wear it, or if the elasticity of the flat rubber is increased so that the opening is sufficiently opened to make it easier to stretch, there is a problem that the foot cover comes off or shifts due to movements such as walking. be.

In particular, as in the case of the foot cover disclosed in Patent Document 1, when a strip-shaped elastic portion is provided with flat rubber or the like over the entire peripheral edge of the opening, the entire peripheral portion expands and contracts uniformly. Two contradictory problems: (1) The elasticity of the flat rubber is small (low) and it is difficult to stretch, so the opening does not open sufficiently when wearing the foot cover, and (2) the elasticity of the flat rubber is difficult to wear. Simultaneously solving the problem that the foot cover comes off or shifts due to movements such as walking because it is large (high) and easy to stretch, covers at least one toenail and does not cover at least one toe base. It is extremely difficult to wear an ultra-shallow foot cover like this.

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 although it is easy to put on and take off when putting on and taking off, the present invention may come off when walking or the wearing position may shift. The purpose is to provide a foot cover that can prevent the foot cover from being damaged.

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 toe and the sole including the sole and exposes the ankle, and is a toe that covers the sole, the side, the sole, and the instep. An opening is provided on the opposite side of the sole of the foot for putting the foot in and out, and an elastic narrow cloth made of a single material is provided along the peripheral edge of the opening. The stretchable narrow fabric has at least a part thereof having a region having low elasticity and being difficult to stretch.

Preferably, the region is a region in which the stretchable narrow fabrics are overlapped and joined, and the stretchable narrow fabrics that are vertically aligned and the stretchable narrow fabrics that are overlapped are aligned. It can be configured to be substantially parallel.
More preferably, the foot cover is formed by joining a first elastic knitted fabric, a second elastic knitted fabric, and a third elastic knitted fabric, and the first elastic knitted fabric is formed by joining the first elastic knitted fabric. The front side side portion, the toe portion, and the toe side opening are formed, the second elastic knitted fabric constitutes the sole portion, and the third elastic knitted fabric constitutes the rear side. The side side portion, the heel portion, and the heel side opening are formed, and the stretchable narrow cloth provided on the peripheral edge of the toe side opening and the elasticity provided on the peripheral edge of the heel side opening. The first elastic knitting having the region formed by joining the narrow cloth so as to overlap each other in the vicinity of the boundary between the first elastic knitted fabric and the third elastic knitted fabric. The ground and the third stretchable knitted fabric can be configured to be joined to the second stretchable knitted fabric.

More preferably, the length in the foot length direction in which the stretchable narrow cloth is overlapped in the region is configured to be equal to or larger than the width in the height direction of the stretchable narrow cloth in the side view of the foot cover. Can be done.
More preferably, the toe portion can be configured to cover at least one toenail and not to cover the base of at least one toe.

According to the foot cover of the present invention, although it is easy to put on and take off when putting on and taking off, it is possible to prevent the foot cover from being taken off or the wearing position is displaced when walking.

It is an overall perspective view of the foot cover which concerns on embodiment of this invention. It is a partially enlarged view of (A) the side view of the little finger side, (B) the side view of the thumb side, and (C) (A) in the state where the foot cover of FIG. 1 is turned upside down.

Hereinafter, the foot cover 100 according to the embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall perspective view showing a wearing state in which the foot cover 100 according to the present embodiment is worn on the foot F, and FIG. 2A is a small finger side in a state where the foot cover 100 shown in FIG. 1 is turned upside down. 2 (B) is a side view of the thumb side thereof, FIG. 2 (C) is a partially enlarged view of FIG. 2 (A). Here, FIGS. 1 and 2 assume a state in which the foot cover 100 is worn on the wearer's foot F. That is, since the foot cover 100 according to the present embodiment is formed of a thin elastic knitted fabric used for pantyhose or the like, if it is not shown in this way, it will be in a shrunk state and have a shape. Since it is difficult to understand, it is assumed as described above. In particular, in FIG. 2, in order to easily understand the characteristics of the foot cover 100, the sole portion 104 is drawn so as to be clearly visible compared to the state in which the foot cover 100 is actually worn.

Hereinafter, the foot cover 100 will be described in detail based on these figures. Here, 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. However, it does not matter basically what kind of fabric constitutes the foot cover, the pattern of the fabric, and the method of joining the fabric. In this foot cover 100, a knitted fabric is used as the fabric. The foot cover structure itself shown below is merely an example.

The fabric forming the foot cover 100 is knitted using a bare heaven (bare heavenly yarn: a yarn (covered yarn, etc.) wound with yarns of other materials (cotton, wool, etc.) around a polyurethane yarn as an axis. 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 change in shape after washing, and (3) soft texture and excellent fit. , (4) It is hard to wrinkle and crease, (5) It has a porous structure and is breathable, and (6) When it contains cotton, it has good touch and hygroscopicity, which is preferable for a foot cover.

Further, the foot cover 100 according to the present embodiment covers the toes and the sole including the heel and exposes the ankle. Here, when the foot cover 100 is worn, it does not matter whether the instep is exposed or not, but when the foot cover 100 is worn, the pumps (mainly the instep portion, which is the opening of the foot, is wide open). When wearing women's shoes), it is preferable that the instep is exposed and the foot cover 100 is hidden by the pumps. Further, in the foot cover 100 according to the present invention, in addition to exposing the instep in this way, the toe portion 102 covering the toe on the instep side covers at least one toenail and covers at least one toe base. It is also preferable to have an ultra-shallow wearing type that does not cover it, and in such an ultra-shallow wearing type, the foot cover 100 is hidden by the pumps even if the instep part, which is the toe, is extremely wide open. preferable.

The foot cover 100 is formed by a sole portion 104, a side side portion 106 (more specifically, a front side side portion 106A and a rear side side portion 106B), a heel portion 108, and a toe portion 102 that covers the toe on the instep side. The opening 118 (more specifically, the opening 118A on the toe side (consisting of the first elastic knitted fabric 120)) and the opening 118A (third) for moving the foot F in and out on the opposite side to the sole 104. An opening 118B) on the heel side (composed of the elastic knitted fabric 130) is provided.

Further, although not limited, the foot cover 100 shown below is shared on the left and right sides, and is preferable in that the left and right sides are not mistakenly worn because the foot cover 100 is 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. As mentioned above, this foot cover 100 is worn on the foot F, and sneakers (so-called athletic shoes regardless of gender) and pumps (shoes mainly for women whose instep part, which is the opening of the foot, is wide or extremely wide open). If you wear shoes such as, the foot cover 100 will not be visible because it will be hidden inside the shoes and the foot cover 100 will not be exposed from the shoes. Here, the fact that the foot cover 100 is not exposed from the shoes when worn includes the fact that the foot cover 100 is hidden by the shoes and becomes invisible or difficult to see.

And, characteristically, this foot cover 100 is made of a single material along the periphery of the opening 118 (more specifically, the elastic narrow fabric 116A on the front side and the elastic narrow fabric 116A on the front side). The elastic narrow cloth 116B) on the rear side is provided. Further, the stretchable narrow cloth 116 includes at least a part thereof having a region having low elasticity and being difficult to stretch (more specifically, a polymerization region 110 described later). The stretchable narrow cloth 116 made of a single material along the peripheral edge of the opening 118 indicates that the material is single, and is limited to one as a member. It does not matter if the stretchable narrow cloth 116 is composed of one or more members instead of the ones.

As for the area where the elasticity is low and it is difficult to stretch, as will be described in detail later, this foot is not the same material and the same dimension (the same dimension here is not the length in the foot length direction (L shown in FIG. 2C)). The width (H shown in FIG. 2C) of the stretchable narrow cloth 116 in the side view of the cover 100 or the short side of the stretchable narrow cloth 116 before being provided on the foot cover 100. The elastic narrow fabric 116 is composed of two members, that is, the front elastic narrow fabric 116A and the rear elastic narrow fabric 116B) that have substantially the same length). In the polymerization region 110, the front elastic narrow fabric 116A and the rear elastic narrow fabric 116B overlap with each other, so that at least a part of the elastic narrow fabric 116 has a low elasticity and is difficult to stretch (polymerization). Area 110) is realized.

However, the region of the foot cover 100 according to the present invention, which is provided by at least a part of the stretchable narrow cloth 116 and has low elasticity and is difficult to stretch, is limited to that realized by superimposing the stretchable narrow cloth 116. It is not something that will be done. For example, the elastic narrow fabric 116 is attached to the elastic knitted fabric (first elastic knitted fabric 120 or the third elastic knitted fabric 130), and the elastic narrow fabric 116 is attached (without overlapping). Even when a part of the pasted fabric is sewn to the elastic knitted fabric (since sutures that are more elastic and easy to stretch than the elastic narrow fabric are not common), the elastic narrow fabric is made into the elastic fabric. By stitching to, it is possible to realize a region that is difficult to stretch in a part of the stretchable narrow fabric.

The front elastic narrow cloth 116A (hereinafter sometimes referred to as the front elastic narrow cloth 116A) has an opening 118A on the toe side (hereinafter referred to as a toe) made of the first elastic knitted fabric 120. The rear elastic narrow fabric 116B (hereinafter sometimes referred to as the rear elastic narrow fabric 116B) provided in the side opening 118A) is a third elastic knitted fabric. It is provided in the heel side opening 118B (hereinafter, may be referred to as a heel side opening 118B) configured by 130.

Here, with respect to the opening 118, the foot cover 100 has a large opening area because it is for shallow wear (suitable for pumps) or for ultra-shallow wear, and does not cover the instep (at all). However, the foot cover according to the present invention having the above-mentioned features is not limited to such shallow wear and ultra-shallow wear. For example, by making the first elastic knitted fabric 120 in which the toe side opening 118A is extended to the instep side to cover the instep, the toe side opening 118A is retracted to the rear side (heel side). The opening area of the opening 118 can be reduced. By changing the first elastic knitted fabric 120 in this way, a foot cover 100 for deep wearing (which does not hide when wearing pumps but hides when wearing sneakers) is realized while maintaining the characteristics of the present invention. It is possible. In this case, the front side side portion 106A covers the instep and the side of the foot.

And preferably, the polymerization region 110 in this foot cover 100 is a region where the front side elastic narrow cloth 116A and the rear side stretchable narrow cloth 116B are overlapped and joined. Specifically, the front elastic narrow fabric 116A and the rear elastic narrow fabric 116B align the positions of the elastic narrow fabric in the vertical direction, and the front elastic narrow fabric 116A and the rear elastic fabric 116A are overlapped with each other. It is substantially parallel to the narrow cloth 116B. As shown in FIGS. 1 and 2, the positions of the elastic narrow fabric 116A on the front side and the elastic narrow fabric 116B on the rear side are displaced by the amount of deviation G in the vertical direction (FIG. 2 (FIG. 2). C)) Although it is represented by shifting, even in such a case, the stretchable narrow region is low in elasticity and difficult to stretch due to the large overlapping portion indicated by H shown in FIG. 2 (C). Since it is realized in the fabric, it means that the positions of the elastic narrow fabric in the vertical direction are aligned. That is, even if the front stretchable narrow cloth 116A and the rear stretchable narrow cloth 116B are slightly misaligned, the area where the stretchability is low and the stretch is difficult because the overlapping portion indicated by H shown in FIG. 2C is large. If the above can be realized in the stretchable narrow cloth, it is satisfied that the front side stretchable narrow cloth 116A and the rear side stretchable narrow cloth 116B are aligned in the vertical direction of the stretchable narrow cloth. And. In terms of design, it is preferable that the front stretchable narrow cloth 116A and the rear stretchable narrow cloth 116B align the positions of the stretchable narrow cloth in the vertical direction without any deviation.

More preferably, the foot cover 100 is formed by joining the first elastic knitted fabric 120, the second elastic knitted fabric 122, and the third elastic knitted fabric 130. The first elastic knitted fabric 120 constitutes a front side side portion 106A (hereinafter, may be referred to as a front side side portion 106A) toe portion 102 and a toe side opening 118A. The second elastic knitted fabric 122 constitutes the sole portion 104. The third elastic knitted fabric 130 constitutes a rear side side portion 106B (hereinafter, may be referred to as a rear side side portion 106B), a heel portion 108, and a heel side opening portion 118B. In the above-mentioned polymerization region 110, the front elastic narrow cloth 116A provided on the peripheral edge of the toe side opening 118A and the posterior elastic narrow cloth 116B provided on the peripheral edge of the heel side opening 118B are the first. It is formed by being joined so as to overlap in the vicinity of the boundary between the elastic knitted fabric 120 of 1 and the elastic knitted fabric 130 of the third. The first elastic knitted fabric 120 and the third elastic knitted fabric 130 having the polymerization region 110 thus formed are joined to the second elastic knitted fabric 120 having the sole shape. There is. The polymerization region 110 is not limited and may be reversed, but in the foot cover 100, the outer side (the side opposite to the side where the foot F contacts: the shoe side) is the first elastic knitted fabric. 120, the inside (the side in contact with the foot F: the skin side) is overlapped so as to be the third elastic knitted fabric 130.

Here, the joining may be any of an adhesive tape, an adhesive, a suture, and other joining methods. That is, the first elastic knitted fabric 120 and the third elastic knitted fabric 130 are joined even in the polymerization region 110 which is the overlapping region of the front elastic narrow fabric 116A and the rear elastic narrow fabric 116B. In either case, the first elastic knitted fabric 120 and the third elastic knitted fabric 130 are joined to the second elastic knitted fabric 120 constituting the sole portion 104, whichever joining method is used. It doesn't matter.

In the foot cover 100 according to the present embodiment, sewing with sutures is adopted as a joining method. Here, in the polymerization region 110, since the front elastic narrow fabric 116A and the rear elastic narrow fabric 116B are overlapped and joined (because the degree of expansion and contraction of the elastic narrow fabric is doubled). In), the polymerization region 110 is a region that is difficult to extend due to polymerization. Further, since the suture thread for joining in this way is generally less elastic than the elastic narrow cloth 116 and is difficult to stretch, the polymerization region 110 is a region that is difficult to stretch by suturing. This is the same even with other joining methods (adhesion with adhesive tape, adhesion with adhesive).

As described above, the foot cover 100 is a first elastic knitted fabric 120 in which the front elastic narrow fabric 116A and the posterior elastic narrow fabric 116B are overlapped and sewn so as to include the polymerization region 110. And the third elastic knitted fabric 130 are integrated, and then the integrated first elastic knitted fabric 120 and the third elastic knitted fabric 130 are combined with the entire second elastic knitted fabric 122. It is formed into a three-dimensional shape by suturing the peripheral edge and the sole suture line 114.

More preferably, the length in the foot length direction (L shown in FIG. 2C) in which the stretchable narrow fabric 116 is overlapped in the overlapping region 110 of the foot cover 100 is the stretchability in the side view of the foot cover 100. It is longer (L ≧ H) than the width (H shown in FIG. 2C) of the narrow cloth 116 in the height direction (short direction). Regarding the degree of overlap of the stretchable narrow fabric 116 in such a polymerization region 110, basically L ≧ H as shown in FIG. 2C, but the elasticity of the stretchable narrow fabric 116 Depending on the case, L ≧ H / 2 may be satisfied, and it is also preferable that the upper limit of L is 2H. That is, for the length L in the foot length direction in which the elastic narrow cloth 116 is overlapped, H / 2 ≦ L ≦ 2H is preferable, especially H ≦ L ≦ 2H, and L≈H (in terms of design). )preferable.

The details of the foot cover 100 having such a feature will be described in more detail.
As described above, the stretchable narrow cloth 116 stretches at least a part thereof over the entire circumference of the upper edge of the opening 118 provided for putting the foot in and out on the opposite side to the sole portion 104. It is provided so as to have a polymerization region 110 which is low and difficult to stretch. In this foot cover 100, the front elastic narrow fabric 116A is placed in the toe side opening 118A of the first elastic knitted fabric 120, and the rear elastic narrow fabric 116B is attached to the third elastic knitted fabric 130. It is attached to each of the heel side openings 118B (without overlapping). Then, when the first elastic knitted fabric 120 and the third elastic knitted fabric 130 are sewn with the side stitch line 112, the front elastic narrow fabric 116A and the posterior elastic narrow fabric 116B are overlapped with each other. The combined polymerization region 110 is formed.

In addition to providing the stretchable narrow cloth 116 over the entire circumference of the upper edge of the opening 118 in this way, the stretchable narrow cloth 116 includes at least a part thereof having a polymerization region 110 having low elasticity and being difficult to stretch. Therefore, when the elastic narrow fabric 116 is stretched when the foot cover 100 is worn, the opening 118 is wide open, so that it is easy to wear, and after the foot cover 100 is worn, the elastic narrow fabric 116 is easy to wear. The foot cover 100 does not come off during walking because the opening 118 is reduced by contracting. That is, in this foot cover 100, although the stretchable narrow cloth 116 is provided over the entire circumference of the upper edge of the opening 118 like the conventional foot cover, the whole thereof does not expand and contract uniformly. As shown by the black-painted arrow (shorter than the white-painted arrow) in FIG. 2C, the polymerization region 110 is less likely to expand and contract than the other regions, and is longer than the black-painted arrow (longer than the black-painted arrow). As shown, the other regions are provided with a polymerization region 110 which is more likely to expand and contract than the polymerization region 110, and which is difficult to partially expand and contract on the side of the foot cover 110. When the foot cover 100 is worn, the stretchable narrow cloth 116 (occupying most of the stretchable narrow cloth 116) other than the overlapping region 110 is large and can be easily stretched, so that the opening 118 is wide open. It is easy to wear, and after wearing this foot cover 100, the stretchable narrow fabric 116 of the overlapping region 110 (although it is small as a region) cannot be easily stretched, so that it is lateral to the opening 118 (of the foot). The foot cover 100 does not shift or come off during walking in order to firmly tighten the foot on the side).

As described above, according to the foot cover 100, two contradictory problems, which are the problems to be solved by the present invention, are (1) when the foot cover is worn because the elasticity of the flat rubber is small (low) and it is difficult to stretch. At least one problem is that the opening is not fully opened and it is difficult to wear, and (2) the foot cover comes off or shifts due to movements such as walking because the flat rubber has large elasticity (high) and is easy to stretch. Even an ultra-shallow foot cover that covers one toenail and does not cover the base of at least one toe can be solved at the same time.

In the foot cover 100 according to the present embodiment, the stretchable narrow cloth 116 covers only the inside of the foot cover 100 (the side in contact with the foot F: the skin side) over the entire circumference of the upper edge of the opening 118. Is provided. Further, the elastic narrow cloth 116 is provided only on the outside of the foot cover 100 (the side opposite to the side where the foot F contacts: the shoe side), or on the outside and the inside over the entire circumference of the upper edge of the opening 118. It doesn't matter.

Here, the case where the stretchable narrow cloth 116 is provided on the outside and the inside in this way is not limited, but is described in JP-A-2014-133952, for example, which has been filed and published by the applicant of the present application. The stretchable narrow cloth 116 may be folded back and provided so that the folded line substantially coincides with the upper edge of the opening 118. As a result, approximately half of the width of the elastic narrow fabric 116 is on the inside of the foot cover 100 (inside where the foot F is in contact: the skin contact surface side), and the other side of the width of the elastic narrow fabric 116. A stretchable narrow cloth 116 is provided straddling the outside of the foot cover 100 (the outside on the opposite side where the foot F is in contact: the opposite surface of the skin contact surface), which is approximately half of the foot cover 100. In this case, the width of the stretchable narrow cloth 116 in the height direction (H shown in FIG. 2C) in the side view of the foot cover 100 is approximately 1/2 of the stretchable narrow cloth 116. Also in this case, the length in the foot length direction (L shown in FIG. 2C) on which the elastic narrow fabric 116 is overlapped is the height direction of the elastic narrow fabric 116 in the side view of the foot cover 100. Needless to say, it satisfies the condition that it is longer (L ≧ H) than the width (H = approximately 1/2 of the stretchable narrow cloth 116 shown in FIG. 2C).

Further, the inside of the foot cover 100 (the side in contact with the foot F: the skin side) at the upper edge of the heel portion 108 of the foot cover 100 is formed of a thin transparent sheet such as a linear silicone resin or a silicone resin. It is also preferable to provide the heel non-slip 150. In this foot cover, not a sheet but three corrugated and linear silicone resins are provided. Then, in the portion where the heel non-slip 150 is provided, the stretchable narrow cloth 116 (more specifically, the heel side stretchable narrow cloth 116B) is placed in the height direction in the side view of the foot cover 100 (FIG. 2 (FIG. 2). The width in the direction parallel to H shown in C) is larger than that of the other portions. As described above, in the heel portion 108 of the foot cover 100, the width of the elastic narrow cloth 116 is widened to provide the heel portion non-slip 150, so that the adhesion of the foot F to the heel is improved and the foot cover 100 is attached to the foot. It is possible to further prevent the F from shifting from the heel portion. It should be noted that such a structure of the heel portion 108 is not an essential structure in the foot cover according to the present invention.

Further, but not limited to, in the foot cover 100, the second elastic knitted fabric 122 constituting the sole 104 absorbs moisture so as to absorb the sweat generated when the foot cover 100 is worn. It is also preferable to prepare. For example, the second elastic knitted fabric 1
As 22, a fabric having a higher hygroscopicity and easier to absorb sweat than the first elastic knitted fabric 120 and / or the third elastic knitted fabric 130 is adopted. Thereby, the entire region of the sole portion 104 can be provided with hygroscopicity. It should be noted that such a hygroscopic region may be provided not on the entire sole but on a part of the sole.

Further, in the sole portion 104, the sole portion formed of a thin sheet such as silicone resin is formed on the side opposite to the side in contact with the foot F (the side in contact with the inner sole of the pump when wearing the pump, which is an example of shoes). It is also preferable to provide a non-slip. This makes it possible to improve the adhesion to the inner bottom of the pump and prevent the position of the foot cover 100 from shifting in the pump. It should be noted that this non-slip sole is not an essential configuration for the foot cover according to the present invention.

In the foot cover 100, the first elastic knitted fabric 120, the second elastic knitted fabric 122, the third elastic knitted fabric 130, and the elastic narrow fabric 116 forming the foot cover 100 are formed. And may be formed of the same fabric. That is, the foot cover 100 may be all made of the same elastic knitted fabric (tricot or the like) with respect to the knitted fabric. In the foot cover 100, the elastic narrow fabric 116 is used as the elastic knitted fabric (more specifically, the front elastic narrow fabric 116A is used as the first elastic knitted fabric 120, and the rear elastic narrow fabric 116 is used as the elastic knitted fabric. The 116B is attached to the third elastic knitted fabric 130), and the adhesive applied to the elastic narrow fabric 116 is melted by heating with a hot press device and is heat-bonded to the elastic knitted fabric. ..

Further, in the foot cover 100, the first elastic knitted fabric 120, the second elastic knitted fabric 122, and the third elastic knitted fabric 130 forming the foot cover 100 are formed instead of the same fabric. It doesn't matter (three different knitted fabrics or two are the same knitted fabric), the first elastic knitted fabric 120, the second elastic knitted fabric 122, the third elastic knitted fabric 130, and the elastic narrow width. It does not matter if the fabric 116 is formed instead of the same fabric (four different knitted fabrics or at least two are the same knitted fabric).

As described above, according to the foot cover 100 according to the present embodiment, the stretchable narrow cloth 116 (front side stretchable narrow cloth 116A and the rear side) made of a single material along the peripheral edge of the opening 118. Elastic narrow fabric 116B) is provided, and the elastic narrow fabric 116 has at least a part thereof having low elasticity and difficult to stretch (front elastic narrow fabric 116A and rear elastic narrow fabric 116B). It is provided with a polymerization region 110) in which the above layers are overlapped and sewn together. In addition to providing the stretchable narrow cloth 116 over the entire circumference of the upper edge of the opening 118 in this way, the stretchable narrow cloth 116 includes at least a part thereof having a polymerization region 110 having low elasticity and being difficult to stretch. Therefore, when the elastic narrow fabric 116 is stretched when the foot cover 100 is worn, the opening 118 is wide open, so that it is easy to wear, and after the foot cover 100 is worn, the elastic narrow fabric 116 is easy to wear. The foot cover 100 does not come off during walking because the opening 118 is reduced by contracting. For this reason, even with an ultra-shallow foot cover that covers at least one toenail and does not cover the base of at least one toe, (1) the elasticity of the opening is small (low) and it is difficult to stretch. When wearing the foot cover, the opening does not open sufficiently and it is difficult to wear it. (2) The elasticity of the opening is large (high) and it is easy to stretch, so the foot cover may come off or shift due to movements such as walking. The problem can be solved at the same time.

It should be noted that the embodiments disclosed this time are exemplary in all respects and are not restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

The present invention is suitable for a foot cover worn with bare feet, and is particularly preferable in that it is easy to put on and take off when putting on and taking off, and the foot cover does not come off or the wearing position does not shift when walking.
