DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock which has an effect of preventing the heel and the sole of the foot from drying out on the keratinized portion.

[0002]

2. Description of the Related Art When the air is dry as in winter, the skin tends to dry and become keratinized. In particular, the keratin of the soles of the soles and the skin of the fingers are remarkably keratinized, and if it becomes severe, cracks will occur, causing severe pain when touching objects and hanging on the fibers of socks etc. Is the cause. Therefore, the inventor of the present invention has disclosed Japanese Patent Application No. 3-12887.
No. 2, Japanese Patent Application No. 7-195566, Japanese Utility Model Application No. 7-7904
Proposed an anti-drying sock.

The drying prevention sock proposed by the inventor in Japanese Patent Application No. Hei 3-128872 has an inner layer 11 as shown in FIG.
In a two-layered sock consisting of an outer layer 12 and an outer layer 12, a non-breathable sheet 13 is attached between the inner layer 11 and the outer layer 12 at the heel to prevent the heel from drying and keep the entire foot warm. This is a sock 10 for preventing drying, which has an effect of enhancing the soybeans. As shown, the inner layer 11 and the outer layer 12
Are mutually attached and integrated at the fingertip portion P1 and the opening portion P2.

The drying prevention socks proposed by the inventor in Japanese Patent Application Nos. 7-195566 and 7-7904 are envelopes made of a non-breathable sheet at the inner heel of a two-layered sock. The covered socks for drying prevention and the heel are covered with an enclosure made of a non-breathable sheet, and both sides of the sole except for the toe are covered with a pair of enclosures made of a non-breathable sheet to form an inner layer. It is a drying prevention sock that has been attached to the sock.

[0005]

The drying prevention socks proposed in the above-mentioned application are intended to prevent the heel from drying, so that the heel of the sole of the foot can be surely prevented from drying. However, in all of the anti-drying socks, 2
Because of the layered structure, there is a problem in that the shoe becomes thick and becomes cramped when the socks of the present invention are worn, even if the shoe is of an optimal size when wearing ordinary socks. It is uneconomical to prepare shoes of different sizes to wear the socks of the above invention, and there is a demand for women to wear shoes as small as possible. There was a problem that it was difficult. In addition, there is a problem that socks having a two-layer structure as a whole are difficult to dry when washed. In particular, such socks are worn more often in winter, but in winter the temperature is low and the sunshine is low, so it is difficult to dry.

Under these circumstances, there has been a demand for a sock that is as thin and easy to dry as possible, while having a structure that can prevent the heel from drying. The applicant has separately filed a so-called anti-drying sock having a single-layer structure in which only the heel portion has a two-layer structure and a non-breathable layer is interposed between the inner layer and the outer layer. did. Since this is a single-layer structure as a whole, it became thinner and was not cramped even when wearing conventional shoes. It also became easier to dry even after washing. However, since it is not possible to obtain the heat-retaining effect as much as a two-layer sock for drying prevention, it is a two-layer sock for drying prevention and a so-called drying sock that is easy to dry after washing. Socks were desired.

In view of the above, the present invention provides an anti-drying sock having a two-layer structure when used, and an inner layer and an outer layer which can be separated during washing. It is intended for.

[0008]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, there is provided a first sock having a one-layer structure in which a non-breathable layer is formed on an outer surface of a heel portion; It is characterized in that it can be separated from the second sock of a single-layer structure that can be put on the outside of one sock and has no non-breathable layer formed thereon. According to the second aspect of the present invention, the first sock having a one-layer structure in which a non-breathable layer is formed on the inner surface of the heel portion can be placed on the inside of the first sock. The one-layered second sock on which the non-ventilating layer is not formed is characterized in that it is configured to be separable. The non-breathable layer may be composed of a non-breathable sheet fixed to the first sock.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION
This will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a sock for preventing drying according to an embodiment of the present invention, and reference numeral 2 denotes an inner layer formed in a one-layer sock shape covering a foot, which is made of cotton, acrylic, wool, nylon, polyurethane, or the like. It is formed by knitting in the same manner as ordinary socks using a mixed yarn.

Reference numeral 3 denotes a resin non-breathable sheet large enough to cover the heel. This non-breathable sheet is formed of a thin film made of a polyvinyl chloride resin having a high degree of polymerization and a high degree of polymerization of the polyvinyl chloride resin, and forms a non-breathable layer. The non-breathable sheet 3 is fixed to the outer surface of the heel portion of the inner layer 2 by welding, or by fusing using a high-frequency welder or a heater. With the above configuration, the inner layer 2 has a one-layer structure, but has a two-layer structure having a drying prevention function by fixing the non-breathable sheet 3 only at the heel portion.

Reference numeral 4 denotes a sock-like outer layer which covers the foot in substantially the same size as the outer layer 2, and is manufactured to have substantially the same size as the non-breathable sheet 3 or slightly larger. The outer layer 4 is also formed by knitting using a blended yarn made of acrylic, wool, nylon, polyurethane or the like in the same manner as ordinary socks. As shown in FIG. 2, the first sock A serving as the inner layer 2 and the second sock B serving as the outer layer 4 are completely separated and independent, and are used in an overlapping manner. It is configured so that it can be separated or separated freely.

The anti-drying sock 1 having the above structure can be manufactured by the following steps. First, a non-breathable sheet 3 sized to cover the heel portion is placed on the first sock A serving as the inner layer 2.
To form a non-breathable layer on the heel. At this time, if the non-breathable sheet 3 is gathered around the peripheral edge while forming a gather, it becomes easy to adjust the shape to cover the convex part of the heel. In this manner, the first sock A including the inner layer 2 in which only the heel portion has the two-layer structure is completed. The second sock B to be the outer layer 4 is manufactured in the same process as the conventional one with the same structure as the conventional one. When the second sock B is superimposed on the first sock A manufactured as described above, the socks 1 for drying prevention have a three-layer heel portion.

The above process is only an example,
Of course, it can be manufactured in different steps.
For example, when fastening the non-breathable sheet 3 to the inner layer 2,
The entire periphery of the non-breathable sheet 3 does not have to be fixed, and only a part may be fixed so as not to shift.

There are three modes of use of the drying prevention sock having the above configuration as follows. The first mode of use is a mode in which a first sock A and a second sock B are worn one upon another. Such a usage form is a basic form,
In addition to preventing the heel from drying out to prevent bulking and cracking, the double footing of the entire foot prevents the foot from getting cold, so the heat retention effect is high. Also, when washing, by separating and washing, a sufficient washing effect can be obtained, and when drying, it is possible to obtain the effect of being easily dried by separating and drying.

The second mode of use is a mode in which only the first socks A are worn. In this case, the effect of preventing the heel portion from drying and preventing the heel portion from being bulky or cracked can be obtained. Also, when washing
Since it has a one-layer structure, a sufficient washing effect can be obtained, and an effect that it is easy to dry when it is dried is obtained. The third usage mode is a mode in which only the second socks B are worn. In this case, the effect of preventing the heel from drying can not be obtained, but it can be used as ordinary socks. Furthermore, since the second sock B can be replaced with a conventional sock on the first sock A, the second sock B can be replaced at any time or a stylish sock that suits one's preference can be used. It is now possible. Thus, the first sock A and the second sock A
Various effects can be obtained by making it possible to separate the sock B from the sock.

In the above embodiment, the case where the non-breathable layer is provided outside the heel portion of the inner layer according to claim 1 has been described. When providing a ventilation layer and using it so as to overlap, the second sock may be overlapped with the inside of the first sock. In addition,
The non-breathable layer may be a layer formed by applying a non-breathable resin to the inner layer. In addition, as a non-breathable sheet,
It is also possible to use not only a high polymerization degree vinyl chloride resin but also various synthetic resins or natural resins such as rubber. The present invention does not limit the shape, material, and fastening means of the non-breathable layer, and the shape of the non-breathable layer is formed only on the heel portion regardless of the shape, material, and fastening method. It is claimed that the first sock A and the second sock B having no non-breathable layer are formed so as to be separable.

[0017]

According to the present invention, when only the first sock on which the non-breathable layer is formed is removed, the first sock has a one-layer structure.
Compared to a conventional three-layered anti-drying sock, it is thinner and has the effect that the shoe is not cramped, and also has the effect of being easy to dry when washed. By laminating the first sock and the second sock, as in the case of the conventional three-layered sock-drying sock, the effect of preventing the heel from drying and the effect of keeping the heat can be obtained, and the sock can be separated when washing. The effect that it becomes easy to dry is also obtained. Also, since you can put ordinary socks on the first sock,
You can also do fashion according to your preference. Furthermore, even if only the second sock B is used, it can be used as a normal sock. As described above, the drying prevention sock of the present invention has an effect that it can be used for various purposes.
