It is.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention forms two groups of sachets in the longitudinal and lateral continuity directions, and forms an uneven air-permeable nonwoven sheet 1 in which the sachets 2 are filled with charcoal particles 3, and a predetermined thickness. The intermediate core material 4 and the backing material 5 are cut in accordance with the shape of the bottom of the footwear, and at least the entire periphery of the breathable nonwoven sheet 1 is covered among the cut surfaces of the edges of each material in which they are overlapped. Cover with sheet band 6. Then, the breathable nonwoven sheet 1 and the intermediate core material 4 or the peripheral portions of the intermediate core material 4 and the backing material 5 are integrally sewn, and a bottom structure of the shoe is formed by superposing on the upper surface of the bottom of the shoe.

[0006] Further, a group of small bags 2 is formed in a continuous vertical and horizontal direction, and the uneven air-permeable nonwoven sheet 1 formed by filling the small bags 2 with charcoal particles 3 is cut in accordance with the bottom shape of the footwear. The air-permeable nonwoven sheet 1 is superimposed on the upper surface of the intermediate core material 4 of the shoe, and the bottom lower surface material 8 is arranged below the lower surface material. In both cases, the entire periphery of the breathable nonwoven sheet 1 is covered with the covering sheet band 6. The footwear has a bottom structure in which the air-permeable nonwoven sheet 1 and the intermediate core member 4 or the edge portions of the intermediate core member 4 and the bottom lower surface member 8 are integrally stitched.

Further, in each of the above configurations, the size of the pouch 2 is about 5 mm in width and about 20 mm in length.

Further, in each of the above configurations, the size of the charcoal particles 3 is set to 0.1 to 1. 0 mm.

[Embodiment of the invention]

 The present invention relates to the structure of the bottom part of footwear such as shoes, sandals, clogs or slippers. The embodiment of the present invention is described below with respect to a slipper shown in FIG. 1 and a shoe insole shown in FIG. explain in detail.

First, the shoe insole according to the present invention will be described. As shown in FIGS. 4 and 5, two groups of pouches are formed in a continuous longitudinal and lateral direction, and the pouches 2 are filled with charcoal particles 3. Fit the uneven breathable nonwoven sheet 1 made of PP resin, the intermediate core material 4 made of felt or EVA foamed resin and the like, and the backing material 5 made of PVC laser etc. according to the bottom shape of the footwear. To cut. In order to prevent the charcoal particles 3 from escaping from the pouch 2, at least the entire circumference of the air-permeable nonwoven sheet 1 is cut out of a cut surface of each material edge portion made of cloth or resin sheet. Is covered with the covering sheet band 6. Then, the periphery of the breathable nonwoven sheet 1 and the intermediate core material 4 or the intermediate core material 4 and the backing material 5 are integrally sewn with a thread 9 and placed on the bottom upper surface of the shoe.

Next, the slipper of the present invention will be described. As shown in FIG. 3, two groups of pouches are formed in a continuous vertical and horizontal direction, and the pouches 2 are made of PP resin in which charcoal particles 3 are filled. The uneven breathable nonwoven sheet 1 is cut in accordance with the bottom shape of the footwear. Then, the breathable non-woven sheet 1 is superimposed on the upper surface of the intermediate core material 4 made of felt or EVA foamed resin, and the bottom lower surface material 8 is arranged below the lower surface. In order to prevent the charcoal particles 3 from spilling out of the pouch 2 from the cut surface of the edge, at least the entire periphery of the breathable nonwoven sheet 1 is covered with a covering sheet band 6 made of cloth or resin. I do. Also, the cut surfaces of the peripheral portions of the intermediate core member 4 and the bottom lower surface member 8 are covered with a covering sheet band 7 made of cloth, resin sheet or the like all around. Then, the peripheral edge portions of the air-permeable nonwoven sheet 1 and the intermediate core member 4 or the intermediate core member 4 and the bottom lower surface member 8 are integrally stitched with a thread 9. The intermediate core material 4 may be further laminated in a plurality,

The size and the shape of the pouch 2 in the configuration of the insole and the slipper can be various, but it is most preferable that the width is about 5 mm and the length is about 20 mm. The size of the pouch 2 may be 5 mm in both the vertical and horizontal directions, and may be about 5 mm in length and about 20 mm in width.

The size of the charcoal particles 3 to be filled therein is 0.1 to 1.0 mm in order to form a gap between the particles and maintain high air permeability. In particular, 0.5 to 1.0 mm is preferable. Therefore, it is preferable that the cloth of the breathable nonwoven sheet 1 does not allow the charcoal particles 3 to pass through and can ensure the maximum breathability. The raw material of the charcoal particles 3 may be either white coal or black coal, and among them, bincho charcoal is preferred.

In order to prevent damage due to abrasion or the like caused by use, and to prolong the durability, a cloth having a higher ventilation property may be provided on the upper surface of the breathable nonwoven sheet 1. The fibers of the cloth may be those containing chemicals such as fungicides and deodorants.

[0015]

[Effect of the invention]

 As described above, the bottom structure of the footwear of the present invention is such that the charcoal particles 3 are filled in each of the pouches 2 of the pouch 2 of the breathable non-woven sheet 1 and each time the user walks, the pouch 2 is placed in the pouch 2. When the sole of the foot is stepped on, the ventilation is forcibly generated, and the sweat of the sole increases the humidity, and the air containing the bad smell generated by the propagation of bacteria actively contacts the surface of the charcoal particles 3. Effective performance such as fungicide, deodorant and moisture absorption is exhibited. Then, due to the continuous uneven surface of the two groups of pouches filled with the charcoal particles 3 formed on the surface, an appropriate acupressure effect can be obtained without pain.
