Abstract

PROBLEM TO BE SOLVED: To solve the problem that the heel parts are brought into a state in which keratinization is easily progressed by drying of the heel parts caused by evaporation of moisture included in the heel parts of feet from the heel covering parts during wearing socks as conventional socks have air permeability in the whole part of them. SOLUTION: In these socks comprising an air permeable fabric, evaporation of moisture in the heel parts of feet is prevented and, in case when the part is already keratinized, the keratinized part can be cured by enhancing moisture retention of the heel part in a state of wearing the socks by attaching an impermeable sheet 3 to the heel-covering part 2 of the sock body 1 to inhibit the air permeability of the heel-covering part 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock for preventing heel dryness, which can prevent cracking and keratinization of a heel portion of a foot.

[0002]

BACKGROUND OF THE INVENTION In winter, when the air is dry, the skin of a person is also apt to dry, especially at the heel of the foot, where the skin is too thick and tends to dry out. And when the heel part of the foot becomes excessively dry,
Since the skin is thick, the skin becomes keratinized and easily becomes rusty, and when it becomes more severe, cracks may be formed in the rusted heel.

[0003] By the way, while socks need a heat retaining function, they need a function to prevent stuffiness of the feet due to sweating when worn (when they get humid, they tend to propagate athlete's foot and are unsanitary). Socks are generally made of breathable fabrics.

[0004]

However, in the conventional socks, since the entire sock has air permeability, moisture (moisture) at the heel portion of the foot also diffuses from the heel covering portion of the sock into the atmosphere. This impairs the moisture retention of the heel portion of the foot. In particular,
In the winter season, the air is easy to dry and the sweat is hard to sweat at low temperatures, so that, for example, the degree of dryness of the heel portion of the foot is significantly higher than in the summer season. In addition, people who have long life time wearing shoes have a relatively good moisturizing property of the heel part by covering the heel part even with shoes, but for example, living with socks like a housewife at home For a person who has been in the room for a long time, the amount of water released from the heel portion through the sock increases, and the heel portion tends to be keratinized.

[0005] As described above, in the conventional socks, since the heel covering portion also has air permeability, moisture in the heel portion of the foot diffuses from the heel covering portion of the sock when the sock is mounted, and the heel covering portion of the foot is worn. There was a problem that keratinization (and thus cracking) easily proceeded.

The present invention has been made in view of the above-mentioned problems of the conventional socks, and provides a heel drying prevention sock capable of preventing moisture from escaping from the heel covering portion of the sock when the sock is worn. The purpose is.

[0007]

The present invention has the following structure as means for solving the above-mentioned problems. still,
The present invention is directed to a heel drying prevention sock that can prevent the heel portion of the foot from drying. The invention according to claim 1 of the present invention is directed to a sock made of air-permeable fabric, in which a non-breathable sheet is attached to a heel covering portion of a sock body to prevent the heel covering portion from breathing. It is characterized by having. In addition, the heel drying prevention sock of the present application also includes stockings.

[0008] The sock body is formed into a sock shape by knitting a yarn (including an elastic yarn in general) with a knitting machine. Further, as the non-breathable sheet used in the first aspect, an appropriate thin sheet having no breathability can be adopted.

The non-breathable sheet is sewn with a thread, bonded with an adhesive, or heat-fused to the heel covering portion of the sock body (when the non-breathable sheet is a heat-fusible resin film). And so on. or,
When this non-breathable sheet is attached to the inner surface of the heel covering,
Although it is not visible from the outside, the appearance does not deteriorate, but when it is attached to the outer surface of the heel covering portion, the outer surface of the non-breathable sheet may be covered with a decorative cloth so that the non-breathable sheet is not exposed to the outer surface of the sock.

In the sock for preventing heel drying according to the first aspect, the non-breathable sheet attaching portion faces the heel portion of the foot when worn, and covers the heel portion of the foot with the non-breathable sheet substantially in close contact. Become. Therefore, in the wearing state of the socks for preventing heel drying, moisture (for example, sweat water) in the heel portion of the foot is blocked by the non-breathable sheet and is not radiated to the outside from the heel covering portion of the sock. Can have good moisturizing properties. The invention according to claim 2 of the present invention relates to a sock made of a breathable fabric, wherein a non-breathable synthetic resin is applied to a heel covering portion of a sock body to prevent the heel covering portion from breathing. It is characterized by doing so.

As the non-breathable synthetic resin used in the second aspect, for example, a resin (for example, a urethane-based resin) having a property of being liquid when heated and solidifying to a flexible state at normal temperature is employed. The non-breathable synthetic resin may be applied to only one of the inner surface and the outer surface of the heel covering portion of the sock body, or may be applied to both the inner and outer surfaces of the heel covering portion.

In the sock for preventing heel drying according to the second aspect, the heel covering portion coated with the non-breathable synthetic resin at the time of wearing faces the heel portion of the foot. The part is covered almost in close contact. Therefore, even when the heel drying prevention sock is worn, moisture in the heel portion of the foot is blocked by the non-breathable synthetic resin applied portion (heel covering portion) and does not emanate to the outside from the heel covering portion of the sock. Can improve the moisture retention of the heel portion of the heel.

The heel drying prevention sock of the first embodiment shown in FIGS. 1 to 4 is configured by attaching a non-breathable sheet 3 to a heel covering portion 2 of a sock body 1. The sock body 1 employs ordinary socks, but also includes stockings.

As the non-breathable sheet 3, a suitable thin sheet having no air permeability and flexibility such as a synthetic resin film (for example, a polyvinyl chloride resin film or a polyurethane resin film) or a rubber thin sheet can be used. It is.
In the first embodiment, the non-breathable sheet 3 is the same as that shown in FIG.
As shown in FIG. 3, a notch 3c is provided in a part of the bottom surface 3a to form a horseshoe shape, and a rising side surface 3 having a predetermined height (for example, a height of about 20 to 30 mm) is formed on an outer edge of the bottom surface 3a.
b. That is, the non-breathable sheet 3 is formed into a shape that is substantially in contact with the outer surface of the heel except for the center of the bottom of the heel of the foot.

The non-breathable sheet 3 is sewn to the inner surface of the heel covering portion 2 of the sock body 1 with a thread, bonded with an adhesive, or heat-fused (using a heat-fusible resin film). Case) and the like.
In the sock for preventing heel drying according to the first embodiment, the non-breathable sheet 3 is attached to the inner side of the heel covering part 2 of the sock main body 1. It may be attached to. In this case, since the non-breathable sheet 3 is exposed to the outside and its appearance deteriorates, it is preferable to cover the outer surface of the non-breathable sheet 3 with a decorative cloth.

The sock for preventing heel dryness according to the first embodiment also has a non-breathable portion at the position corresponding to the vicinity of the forward side of the foot when wearing the sock (the portion which is likely to become keratinous next to the heel). Seat 4 is attached. The non-breathable sheet 4 at a position corresponding to the vicinity of the side of the foot at the time of mounting may be provided on each of the left and right sides of the sock body 1.

In the sock for preventing heel drying according to the first embodiment, as shown in FIG. 4, when worn on the foot, the non-breathable sheet 3 faces the heel of the foot. Heel portion of the heel is almost covered. still,
In this mounting state, the non-breathable sheets 4 provided near the feet also face the respective forward side faces of the feet in a substantially close contact state. Therefore, in the wearing state of the heel drying prevention sock, the moisture of the heel portion of the foot is blocked by the non-breathable sheet 3 and is not radiated to the outside from the heel covering portion of the sock. By making it good, it is possible to prevent keratinization of the heel portion. In addition, at the time of wearing, each non-breathable sheet 4 near the forefoot also covers each forward side surface of the foot, and each of the non-breathable sheets 4 also prevents the diffusion of moisture on each side portion near the front of the foot. Is done. The non-breathable sheets 3 and 4 in the sock body 1
In the part without the water, the moisture (moisture) is freely radiated, so that there is no stuffiness (unsanitary) in the socks.

In the sock for preventing heel drying according to the second embodiment shown in FIG. 5, a non-breathable synthetic resin
Is applied to prevent air permeability of the heel covering portion 2. Also in the second embodiment, a similar non-breathable synthetic resin 6 is applied to a position corresponding to the vicinity of each side near the toe.

The non-breathable synthetic resins 5 and 6 used in the heel drying prevention socks of the second embodiment are, for example, those which have a property of being liquid in a heated state and being soft and solidified at room temperature (for example, a urethane-based resin). Adopted. The non-breathable synthetic resin 5 of the heel covering portion 2 may be applied to only one of the inner surface and the outer surface of the heel covering portion 2 of the sock main body 1, or may be applied to both the inner and outer surfaces of the heel covering portion 2. It may be applied. When the non-breathable synthetic resin 5 is applied to the heel covering part 2 in this way, the mesh of the cloth of the heel covering part 2 is filled with the synthetic resin 5 and the heel covering part 2 loses air permeability. .

Even in the heel drying prevention socks of the second embodiment (FIG. 5), the heel covering portion 2 coated with the non-breathable synthetic resin 5 at the time of wearing faces the heel portion of the foot, and The heel portion of the foot is almost completely covered with the resin application portion (heel covering portion 2). Therefore, even in the state of wearing the heel drying prevention socks, moisture (for example, perspiration water) in the heel portion of the foot is blocked by the non-breathable synthetic resin applied portion and is not radiated to the outside from the heel covering portion 2 of the sock. The moisturizing property of the heel portion of the foot is improved, and the keratinization of the heel portion can be prevented from progressing.
