Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a washable slipper in which the slipper and the sole are integrally heat-sealed using a thermoplastic synthetic resin sheet or the same leather as a material.

Conventionally, slippers have been manufactured by heat-sealing slipper-based components made of thermoplastic synthetic resin sheets or the same leather by means such as high-frequency welding, but the soles of conventional slippers of this type are The slipper base is molded as a structure consisting of a foamed resin cushioning material interposed between the upper cover piece and the lower cover piece, and at most one core plate. The sole has a weak waist as a whole, and even if it is initially given some rigidity, it becomes soft in a short period of time, loses its tension and becomes less comfortable to wear, and its durability deteriorates. On the other hand, the peripheral edge of the bottom body is
Since the fused part of the upper and lower pieces is molded to protrude like a brim, there is a risk that the protruding edge may get caught on the sock or damage the sock when worn. had the disadvantage that moisture easily adhered to it.

This invention was devised for the purpose of eliminating the drawbacks of this type of synthetic resin slipper mentioned above, and its intended purpose is to provide extremely high robustness, durability, and comfort. It is an object of the present invention to provide a slipper which is easy to manufacture and inexpensive, has no fused protrusion exposed at the peripheral edge of the sole, and has a completely airtight structure.

The gist of the present invention will be explained below based on the examples shown in the drawings. A sole-shaped core plate 2 made of cardboard is brought into contact with the back side of the shoe 1, and a cushioning material 3 made of foamed resin is interposed between the upper cover piece 1 and the middle core plate 2 at a portion corresponding to the heel. Periphery 1 of top covering piece 1
The upper base A is formed by bending and adhering ' to the periphery of the back surface of the core plate 2.
A sole-shaped core board 6 made of cardboard is placed on the upper surface of the foamed resin sole cushioning material 5 which is interposed on the entire back side of the lower jacket piece 4 which is made of the same material as the upper jacket piece 1. Lower cover piece 4
The lower base B is formed by bending and adhering the peripheral edge 4' to the upper peripheral edge of the core plate 6, and the upper cover piece 1 and the lower cover piece 4 are made of the same material as the upper cover piece C. The periphery 7 is adhered to the back side periphery of the front part of the upper sole A, and the upper surface of the lower sole B is overlapped with the lower surface of the upper sole A, so that the periphery 1' where the upper sole A, the lower sole B, and the flap C are in contact with each other is formed. .

7.4' is characterized by a configuration in which parts are welded by high frequency.

Since the product of the present invention is constructed as described above, during manufacturing, the peripheral edge 1' of the upper cover piece 1 is bent and glued to the back peripheral edge of the cardboard core board 2 with the heel cushion material 3 interposed therebetween. The formed upper sole A and the peripheral edge 4' of the upper cover piece 4 are covered with a sole cushioning material 5.
The lower sole B is formed by bending and adhering to the upper surface periphery of the cardboard core board 6 with the wafer interposed therebetween, and the ridge C constitutes the periphery 7 of the ridge C. After gluing to the bottom B
Lay the top surface on the bottom surface of the top base A,
By heat-sealing the mutually abutting peripheral parts 1' and 7.4' of the lower sole B from the back side of the lower sole B all at once using high-frequency welding means, the upper sole A, the lower sole B, and the flap C are bonded together. A slipper body constituted by the integral joint is formed.

In the thus manufactured slipper of the present invention, the heel part is formed high by inserting the heel cushion material 3, and the front part from the arch part to the toe is made of two cardboard core plates 2.
, 6 are formed as a thin sole body which is sandwiched and joined by the upper cover piece 1 and the lower cover piece 4 under the interposition of the sole cushioning material 5, and as a result, when worn, it imparts appropriate elasticity. At the same time, the front part of the sole of the foot fits well with the sole of the foot, as if in direct contact with the floor surface, and provides a light, stable and comfortable feeling when worn.

Therefore, the front part of the bottom body, which is formed to be relatively thin as described above, is formed by sandwiching and joining the cardboard core plates 2 and 6 with the upper cover piece 1 and the lower cover piece 4. The sole is much stronger than conventional synthetic resin slippers of this type, maintains a stable tension state at all times, prevents deformation, and is highly durable.

Furthermore, the bottom body, which is the main component of the slipper of the present invention, has the upper sole A, the lower sole B, and the collar C integrally formed at the peripheral portions 1' and 7.4' where they contact each other, as described above. As a result of adopting a heat-sealed structure, the peripheral side of the bottom body is formed into a beautiful integral structure with almost no seams exposed, and at the same time the core plates 2, 6 and cushioning material 3.5 are completely sealed. Since the product is housed in an airtight state, the product of the present invention can reliably prevent moisture from entering the bottom body even if the product is soaked in water and washed.

As mentioned above, the slippers of the present invention are simple in structure and manufacture, and the bottom body of the slipper is provided with sufficient tension by the two inexpensive cardboard core plates 2 and 6. This strengthens the waist and makes the shoes comfortable to wear, while at the same time, the circumferential side of the sole is designed so that the heat-fused parts of the upper sole A, lower sole B, and lace C are not exposed to the outside. Because it is molded with a good airtight structure, the product of this invention exhibits outstanding practical effects, especially when used as slippers for bathrooms and toilets with a lot of water, where a low price is desired. .
