Description

[Detailed description of the invention] [Industrial application field] (The invention relates to a shoe insole suitable for preventing athlete's foot.

[Prior art and its problems] Focusing on the fact that copper and aluminum ions have IR bactericidal activity, there is an insole for shoes in which a thin plate of copper or aluminum is fixed to a synthetic resin substrate.

In such a conventional shoe insole, copper or aluminum 13 is caulked to a synthetic resin substrate 11 as shown in FIG. A large number of holes 12 are drilled, and an eyelet-like cylindrical rivet 13 made of copper or aluminum and having 7 flanges + 3b is press-fitted into the upper part of the cylindrical portion 13a using a press machine and crimped.

Therefore, in this method, it is necessary to manufacture a cylindrical rivet, and it is also necessary to attach the rivet 13 to the hole 12 drilled in the substrate by pressing it.

Moreover, in the insole as a product, the L part flange 13 of the cylindrical rivet and one part of the caulking claw 13c must be in close contact with the board so that they bite into the board, otherwise the socks may get caught on the rivet flange 13b. It has the disadvantage of being broken.

(Objective of the present invention) In the present invention, a metal foil pattern is formed by adhering to a substrate and a body, so socks will not get caught in the butter 7, and the pattern will not exert jQ interleaving force. We are now able to provide insoles for shoes that can prevent the occurrence of athlete's foot.

L Structure of the Present Invention The insole for shoes according to the present invention has a large number of metal foils made of a metal on which copper or aluminum τ ions exert a bactericidal effect on at least one side of the insole substrate made of soft synthetic resin. It has a structure in which the pattern is integrally formed with the medium gL substrate by adhesion.

Since the shoe insole of the present invention has a substrate made of a soft synthetic resin material, it can be inserted into the shoe without any inconvenience.

In addition, since a metal foil pattern made of metals such as copper and aluminum is attached to the substrate, ions exert a sterilizing effect, so when the metal foil pattern is electrolyzed by sweat, the metal ions exert a sterilizing effect and are effective against athlete's foot. You can prevent +h from being affected.

Further, the patterned foil can be easily formed on the substrate by plate-making techniques such as photoetching and photoengraving, or by various printing techniques.

[Embodiment] Next, an embodiment of the present invention will be described with reference to a specific example shown in the accompanying drawings.

In Fig. 1.2, reference numeral 1 indicates a shoe insole according to the present invention, which is made of soft synthetic resin.

However, on the upper surface of the insole substrate 1, there is a pattern of metal foil that generates sterilizing power through ionization, for example '! In addition, an appropriate number of metal foil patterns 2 made of 4 are integrally attached to the insole substrate l by photoetching, photoengraving, or other printing means, or by an appropriate printing method. Accordingly, a large number of through holes 3 are made in the insole substrate to prevent moisture from forming on the front and back sides.

Since the shoe insole substrate l of this embodiment is made of a soft synthetic resin material, it does not feel strange even if it is scattered on shoes, and it can be used without damaging the feet.

But inside! In addition, a metal foil pattern 2 made of copper, which is a metal that exhibits sterilizing power through ionization, is formed on the top surface of the substrate l, so that the inside of the shoes and the feet are always sterilized, and the proliferation of various bacteria is prevented. It can be expected to be effective in preventing athlete's foot.

In addition, since the metal foil pattern is not caulked but is integrally formed on the insole substrate by adhesion, the metal foil pattern can be formed into 8-plates by plate-making methods such as photoetching or photoengraving, or by various printing methods. Can be formed.

Moreover, since the metal foil pattern 2 is closely attached to the insole board by the above-mentioned means, there is no fear that the edge of the metal piece will get caught on the sock as in the case of caulking, and it can be used safely.

Furthermore, since the metal foil pattern 2 can be formed by plate-making or printing means as described above, it can be formed into any desired shape and arrangement, making it possible to provide a shoe insole with excellent design effects and high added value.

The insole for shoes according to the present invention has the structure as described above, and an example of its manufacturing method will be described using a photo-etching method as an example.

First, a copper foil layer 2a is formed above a soft synthetic resin substrate 1a (in some cases, a through hole 3 for preventing dampness may be made in advance) which will become an insole substrate. This connects the copper foil to the board 1a.
It is formed by vacuum deposition or by vacuum deposition.

Next, a photosensitive material layer 4 is formed on the upper surface of the copper foil J#2a, a mask plate 5 is pasted on top of the photosensitive material layer 4, and a resist layer portion is formed by exposure to light at a portion of the photosensitive material layer 4 that corresponds to the pattern transparent portion 6 of the mask plate 5. After forming 4a, the non-exposed parts of the photosensitive material layer (excluding the resist layer) and the parts of the copper foil layer other than the resist layer are sequentially dissolved and removed by an appropriate etching process, and an appropriate number of metal foils are formed on the substrate. A pattern 72 is formed, and then the substrate is cut into a foot shape to produce an insole.

In addition to the above-mentioned photoetching method, the insole for shoes of the present invention may be manufactured by photolithography or other appropriate printing methods, but a detailed explanation of these methods will be omitted.

L effect] The shoe insole according to the present invention described above has a metal foil pattern formed on the upper surface of the insole body, which is made of a metal that exhibits sterilizing power through ionization.

The inside of the shoes and the feet are sterilized by the ions generated during electrolysis of the metal foil pattern due to sweat, etc., and it is possible to sufficiently prevent athlete's foot from getting infected.

Moreover, since the pattern on the substrate is made of metal foil and is integrally formed with the substrate by adhesion, the shoes F will not be caught on the edges of the pattern and be torn, and can be used safely.

Furthermore, the metal foil pattern is made by photo etching or photo g11.
It can be easily formed on the substrate by printing or by printing, at a much lower cost than the conventional method of attaching metal cylindrical ribs by caulking. It has the advantage of being able to manufacture shoe insoles with excellent design effects.
