Description

Shoe insole {Bio-ceramic insole}

The present invention relates to a sanitary shoe insole for improving the health preservation of a shoe wearer.

The shoes used for walking on foot are various kinds such as sneakers, basketball shoes, hiking boots, cold weather shoes, and boots, and the material and structure of the shoe rugs used here vary greatly depending on the purpose of use. Footwear cushioning, deodorization, hygroscopicity, antibacterial and breathability have been required for shoe rugs, such as low fatigue and comfort, and no foot odor or moisture to prevent athlete's foot, eczema and bacteria. Carrying shoe rugs have developed a lot by using physical phenomena and developing various materials.

Conventionally developed shoe insoles attach magnet pieces to the surface of the insole, and the magnetic force lines generated here stimulate the capillaries distributed on the soles of the feet to release germanium and far-infrared rays that release oxygen ions in addition to the usual insoles that promote blood circulation. Mixed with soft resins such as PVC and EVA, and injection molding in shoe insole molds to remove athlete's foot, eczema and bacteria by oxygen ions released from germanium, and are distributed on soles with far-infrared rays emitted from silicon compounds. There is a manufacturing method of a shoe insole containing germanium component that stimulates blood and activates various organs of the human body (Patent application No. 94-23021, 1994) and also transfers sanitary processing material to textile fabrics such as absorbent nonwoven fabric as a breathable insole. After bonding by treatment method, teaching or monofilament with cushion material Breathable sanitary insole with antibacterial, deodorant, sweat absorption, and far-infrared light, characterized in that obtained by welding by weaving or weaving into a honeycomb tissue and inserting the sanitized fabric between the cushioning fabric and putting it in a mold for insole. (Application No. 92/32/1992, Patent Application No. 92-3293), and the upper and lower covers of perforated surface cover and waterproof sheet for perforating the feet to quickly absorb sweat from the bottom of the shoe. It is made by inserting the primary absorbent paper and the secondary absorbent fiber, which is a multi-fiber multi-chain, containing the sterilized deodorant such as metal ions or ceramics inside the sweat absorbent chamber by forming a sweat absorbing chamber inside by high frequency bonding. There are also sweat absorbers for shoes (filed March 9, 1997, patent application No. 1997-9730), but these shoe rugs partially meet the requirements to be provided. As well as attempting to solve the problem had a weak practicality.

The present invention is mixed with a large amount of ocher and a little jade, biotite and rosin powder in viscous body supplemented with pulp to the tough fiber of Doc, a raw material of Korean paper, mixed with a large amount of ocher, biotite and rosin powder. The conventional cardboard is cut into a shape of a shoe rug, and then a large number of pores are laid to form a rug board (1), and the EVA resin boards with a plurality of holes (4) installed on both sides of the rug board (1) are interposed. Press welding was carried out.

1: Rug board 2: Perforation 2 ': Perforated fusion part 3, 3': EVA resin sheet

4,4 ': Long field 5: surrounding fusion zone 6,6': space

The shoe insole of the present invention is ocher 55% (weight ratio), jade 7.5% (weight ratio), biotite 7.5% (thickness) on the viscous body of 20% (weight ratio), pulp 10% (weight ratio) By mixing powder of powder and some rosin and cutting the paperboard and floating dry cardboard in the shape of a shoe rug, and then laying a large number of pores to form a rug board (1) and thus forming a rug board ( 1) There are many long holes (4) (4 ') on both sides of upper and lower sides, and the EVA resin plates (3) (3'), which are slightly wider than the rug board (1), are pressed against each other. This is the configuration.

The insole of the present invention configured as described above is insole made of cardboard mixed with 55% of far-infrared radiation loess, based on conventional Korean paper supplemented with 10% of pulp and 10% of strong fiber. Silica, alumina, zirconia, and fume titanium, which have various emission wavelengths, can cover 4-16 microns (µm), which is the absorption wavelength of the human body, and efficient and far-infrared radiation is distributed on the sole and connected to each part of the body. Promotes blood circulation by stimulating meridians, which contributes to peripheral vascular circulation and metabolism.

In addition, far-infrared rays are hygroscopic, deodorant, and antibacterial, so they absorb and remove sweat or moisture from the soles of the feet to maintain cleanliness and deodorize odors, thus acting as a bacterium for athlete's foot.

In addition, the rug substrate 1 mixed with a large amount of loess, which is a far-infrared radiator, serves to maintain and reinforce the shape of the rug substrate 1 as a cardboard made of a raw material of strong fibrous ducts. Sex, warmth, and hygroscopicity further extended the effect of yellow soil.

On the other hand, the covering board 1 is formed on the EVA resin plate 3, 3 'wider than the covering board 1 at the top and bottom edges of the pores 2 of the covering board 1 and the edges of the EVA resin sheet 3, 3'. (2 ') (3) (3'), which is covered by EVA resin sheet (3) (3 '), and reinforced by EVA resin plate (3) (3'). There is a lot of snow and space (6) (6 ') is formed between the EVA resin thin plate (3) (3') and the rug board (1) to help the moisture absorption, deodorization, antibacterial action in the shoes The spaces 6 and 6 'provide cushioning to maintain foot comfort, and the uneven surface of the long holes 4 and 4' has an acupuncture effect by acupressure.

In addition, rosin promotes aeration by inhibiting excessive moisture absorption of the rug and the mattress board (1) and the adhesive action to strengthen the bonding of far-infrared powders such as fiber and ocher of doc and pulp as a material in the papermaking process.

The shoe insole of the present invention configured as described above can be used upside down alternately.

The present invention configured as described above has a blood circulation promoting and metabolic effect due to far-infrared radiation, a cushioning effect and a bedding effect due to buffering, and breathability, hygroscopicity, and antimicrobial properties.
