Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe with a sterilizing function capable of suppressing the generation of malodor caused by bacteria and athlete's foot caused by mold.

[0002]

2. Description of the Related Art Generally, men's leather shoes and high heels have less breathability than sports shoes and sandals, so that they are apt to sterilize and mold, which tends to cause foul odors and athlete's foot. is there.

In order to prevent this, conventionally, an insole made of antibacterial fibers having an antibacterial effect, an insole woven with activated carbon having a high deodorizing effect, or an insole made of a copper plate or a plastic containing copper powder having a bactericidal effect, etc. By laying the shoes on the bottom of the shoes, the malodor and mold growth that occurs from inside the shoes are suppressed.

[0004]

By the way, such a conventional method for preventing malodor has the following drawbacks. First, the method of using an insole made of antibacterial fiber having an antibacterial effect has a drawback that the bactericidal effect period is short because the fiber itself is coated with a bactericide. Next, the method of using an insole woven with activated carbon, which has a high deodorizing effect, can exert a high deodorizing effect, but it does not have the ability to sterilize the bacteria and mold that have propagated in the shoes. No fundamental solution to prevent athlete's foot is made. Further, the method of using a copper plate having a sterilizing effect or an insole made of a plastic containing copper powder has a drawback that a large sterilizing effect cannot be obtained. Moreover, in the method of using the insole as described above, when the shoes are taken off or put on, in addition to being easily lost or bent and damaged, in order to maintain the sterilization effect for a long time,
These have to be replaced regularly, which is disadvantageous in that the cost increases.

Therefore, the present invention has been devised in order to effectively solve such a problem, and an object of the present invention is to achieve a novel bactericidal effect economically and for a long period of time. To provide shoes with various sterilization functions.

[0006]

In order to solve the above-mentioned problems, the present invention comprises, on the inner surface of the shoe body, a copper fiber layer made of copper fibers or a silver fiber layer made of silver fibers, or made of copper fibers and silver fibers. It is provided with a sterilization layer composed of a mixed fiber layer.

That is, according to the present invention, a sterilizing layer made of metal fibers such as copper or silver is provided on the inner surface of a shoe in which various bacteria and molds (particularly white bacillus) are easily propagated. The so-called trace metal action such as) is used to prevent the growth of bacteria and mold that propagate on the inner surface of shoes.

Further, by fixing the sterilization layer to the inner surface of the shoe with a plurality of fastening needles, the sterilization layer will not be displaced or damaged when the shoe is taken off or put on. Further, in addition to this, by providing a porous protective layer on the upper surface of the sterilization layer, it is possible to prevent discomfort caused by direct contact of the bare feet with the sterilization layer and damage to the sterilization layer. Moreover, by making it porous, the ventilation between the bare feet and the sterilization layer is favorably performed. Further, it is desirable that the diameter of the copper fiber or the silver fiber forming the sterilization layer is about 30 μm or less. That is, the larger the diameter of these metal fibers, the better the production cost,
Since the bactericidal effect of these metals is proportional to their surface,
This is because the use of thick fibers reduces the surface area, reduces the bactericidal effect, and increases the weight of the entire shoe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a longitudinal sectional view showing an embodiment of a shoe with a sterilizing function according to the present invention, and FIG. 2 is a partially enlarged view showing details of a portion A in FIG.

As shown in the figure, this shoe with sterilization function 1
A sheet-shaped sterilization layer 5 is provided from the inner surface of the sole 3 of the shoe body 2 to the inner surface of the toe 4. This sterilization layer 5
Is one or a plurality of laminated sheets in which ultrafine copper fibers having a diameter of about 30 μm are woven vertically and horizontally, and as shown in FIG. 2, a plurality of clasps 8, 8 ... It is fixed over the upper surface of the toe-toe 4.

On the upper surface of the sterilization layer 5, a porous protective layer 6 is attached. The protective layer 6 is obtained by weaving a cotton yarn, a tetron yarn having excellent hygroscopicity, or a mixed yarn of these into a sheet shape, and perforating a plurality of ventilation holes 7 at intervals of several mm. It has a buffer property and serves to protect the sterilization layer 5.

In the shoe 1 with a sterilizing function of the present invention thus constructed, the copper component, which is the material of the sterilizing layer 5, makes the inner surface of the shoe body 2 highly antibacterial. In addition, bactericidal properties, antifungal properties, etc. can be exhibited.
It is considered that the copper ions in the copper fibers are eluted around the presence of a trace amount of water such as perspiration from bare feet to exert a bactericidal effect. Further, the protective layer 6 is attached to the toe 4 from the inner surface of the sole 3 by a plurality of clasps 8, 8.
Since it is fixed over the upper surface, even if a shock is applied when the shoes are repeatedly taken off or put on, there is no possibility that the shoes will be displaced or bent and damaged. Further, by providing the protective layer 6 as described above on the surface of the sterilization layer 5, it is possible to prevent discomfort caused by the bare feet directly touching the sterilization layer 5 or damage to the sterilization layer 5. Further, by making the protective layer 6 porous, the bare feet and the sterilization layer 5 can be well ventilated, and the surface of the sole 3 and the toes can be prevented from getting wet. Moreover, by providing the sterilizing layer 5 up to the upper surface of the toe 4, the entire toe portion is covered with the sterilizing layer 5, so that athlete's foot caused by white bacillus occurring between the toes is particularly effectively prevented. You can

In this embodiment, the sterilization layer 5 made of copper fibers is used as an example. However, silver fibers are used instead of copper fibers, or a sterilization layer made of mixed fibers thereof is used. Also, the same bactericidal and antifungal effects as copper fibers can be obtained.

[0015]

In summary, according to the present invention, the following excellent effects can be exerted.

As long as the copper fibers forming the sterilization layer are present, an effective sterilization effect can be maintained for a long period of time.

Moreover, since the sterilizing layer is fixed in advance on the inner surface of the sole by a plurality of clasps, damage such as displacement of the sterilizing layer or bending and breaking is prevented.

Further, unlike the conventional insole, there is no need to replace it, so that it is excellent in economic efficiency.

Further, by providing the porous protective layer, damage to the sterilization layer is prevented, and stuffiness and discomfort of the foot are prevented, so that the wearing comfort is improved.
