Description

  The present invention relates to a slipper, and more particularly to a bottom member of a simple slipper which can be easily manufactured.

Conventional slippers are known to have a simple configuration and many components in consideration of ease of wearing. Generally, there are many components but easy-to-wear and long-lasting slippers are widely used in the house.
The component-rich slipper has an insole member that directly abuts the sole, an upper covering member that wraps the toes and the instep, a bottom member that is located on the underside of the slipper and that contacts the floor surface, and It is comprised by the support member etc. which position and couple | bond a base member, a shell covering member, and a bottom member. In addition, it is required that the insole member, the shell cover member, and the support member be wounded with a cosmetic tape around or in the periphery from the viewpoint of aesthetics. Such a slipper has a problem that the manufacturing cost becomes expensive due to the fact that the assembling process is complicated due to the large number of components and that the cosmetic tape needs to be wound.

On the other hand, simple types of slippers are often provided in lodging facilities such as hotels and ryokans and vehicles such as airplanes and buses.
For example, as disclosed in JP-A-7-51101 (Patent Document 1), as a slipper which can be mass-produced inexpensively by an automatic bag making machine, an upper cover member is made of a thermoplastic synthetic resin and is constituted by a bag having a gusset portion A slipper, the bottom member comprising a thick cardboard, a thermoplastic synthetic resin layer provided on one side thereof, and a cushion layer made of fabric provided on the opposite side, wherein the upper cover member and the bottom member are heat-sealed Has been proposed.

However, since this slipper is complicated and long in manufacturing process, the cost becomes high, and the bottom member also has poor cushioning properties, and there is a problem that it is not comfortable to wear.
Further, according to Japanese Patent Application Laid-Open No. 2005-124726 (Patent Document 2), the upper cover member is made of a synthetic resin non-woven fabric having gusset folds, the bottom member is made of a heat embossed non-woven fabric, and both side ends of the upper cover member are A slipper is disclosed which is adhered to the side edges of the bottom member.
However, since the bottom member of this slipper is made of non-woven fabric, it has poor cushioning properties, is easily wetted by water, and although it is a simple slipper, the desired durability can not be obtained.

  Japanese Utility Model Application Publication No. 6-14561 (patent document 3) is a slipper comprising an epithelium and a shell band adhered to a bottom plate and a bottom plate, the bottom plate is formed of a synthetic resin foam, and at least one of the epithelium and the shell band. The surface is made of a thermoplastic resin-laminated creped paper, and the laminated surface of the epithelium and the band is made to face each other, and both ends of the band are adhered to the back surface of the epithelium by an adhesive. It is disclosed that the above-mentioned adhered back surface is adhered to the upper surface of the bottom plate with an adhesive to produce a simple slipper.

  Although the slipper of patent document 3 has cushioning property than the slipper of patent document 1 or patent document 2 by using the synthetic resin foam of 1.5 mm for the baseplate, it can not be said that it is comfortable yet. In addition, it is necessary to use an adhesive to bond the epithelium and the band together and further to bond them to the upper surface of the bottom plate, which causes a problem in that the production takes time and the cost is increased.

Japanese Patent Application Laid-Open No. 7-51101 JP, 2005-124726, A Japanese Utility Model 6-14561

  The present invention solves the problems of the conventional simple slipper, and provides a laminate serving as the bottom member of the slipper that is comfortable to wear, looks good, and can easily be manufactured with durability. In addition, it aims at providing the slipper using this layered product.

In the present invention, the lamination is preferably performed by dry lamination or hot melt lamination.
According to the present invention, the method comprises the steps of: cutting the laminate manufactured by the manufacturing method into the shape of the bottom member of the slipper; and attaching the back member of the slipper to the cut bottom member. The above object is achieved by a method of manufacturing slippers.

Further, according to the present invention, a flexible foam in which the bottom member of the slipper is a cushion, a surface material which is a front portion in the bottom member of the slipper laminated on one side of the flexible foam, and the flexible foam The foam is composed of ethylene vinyl acetate copolymer laminated on the other side, and the bottom member of the slipper is a laminate of three layers composed of a flexible foam, a surface material and a foam of polyvinyl acetate copolymer. The object is achieved by a slipper characterized in that it is cut into the shape of the bottom of the slipper and the back of the slipper is attached to the front side of the bottom of the slipper.
In the present invention, the instep member is made of a flexible foam and a surface material, the foam and the surface material are laminated, and the foam is the side facing the surface material of the bottom member. Is preferred.

According to the present invention, the process of laminating the sheet of the front material which becomes the front part in the bottom member of the slipper on the single side of the flexible foam sheet which becomes the cushion in the bottom member of the slipper A laminate is manufactured by the process of laminating with the foam sheet which consists of an ethylene vinyl acetate copolymer used as the bottom part in the bottom member of a slipper on the other side of a foam sheet. Accordingly, since this laminate can be manufactured from a long sheet, it is possible to manufacture a great number of bottoms for the slippers at one time.
Further, when cutting the laminate manufactured by the above manufacturing method into the shape of the bottom member of the slippers, the bottom members of many slippers can be manufactured at one time by punching or the like.

  According to the present invention, the flexible foam in which the bottom member of the slipper is a cushion, the surface material of the bottom member in the bottom member of the slipper laminated on one side of the flexible foam, and the flexible foam Since it consists of a foam made of ethylene vinyl acetate copolymer laminated on the other side, it has excellent cushioning properties and is very comfortable. In addition, since the surface of the bottom member of the slipper that comes in contact with the floor is made of a foam made of ethylene vinyl acetate copolymer, it is strong and not slippery, and the surface material of the bottom member is also wet when the floor is wet with water. Water does not penetrate until it does not wet the foot.

Furthermore, according to the present invention, the bottom member of the slipper is cut into the shape of the bottom member of the slipper in a state where three layers consisting of a flexible foam, a surface material and a foam of polyvinyl acetate copolymer are laminated. So the cutting surface is beautiful. Thus, it is not necessary to trim the sides of the slippers with a cosmetic tape as in conventional slippers.
According to the present invention, both ends of the back member can be easily attached to the bottom member by sewing or the like, and it does not take time and effort.
In addition, since the back member is also made of a flexible foam and a front material, and the foam and the front material are laminated, manufacture is easy. In addition, since the foam of the back member is the side facing the front material of the bottom member, that is, the side where the foam is in contact with the back of the foot, the slippers are comfortable to wear.

It is sectional drawing of the laminated body used as the bottom member of the slipper of this invention. FIG. 2 (a) is a plan view showing in dotted lines a portion for cutting the laminate to be the bottom member of the slipper into the shape of the bottom member of the slipper, and FIG. 2 (b) is cut to form the bottom member of the slipper It is a perspective view of a layered product. It is sectional drawing of the back member of the slippers of this invention. It is a perspective view of the slippers of the present invention.

Hereinafter, the present invention will be described in detail with reference to the drawings.
The laminate 10 as the bottom member of the slipper manufactured by the method of the present invention has a three-layer structure as shown in FIG. 1 and is made of an ethylene vinyl acetate copolymer as the bottom of the bottom member of the slipper. It comprises a foam sheet 11, a flexible foam sheet 12 serving as a cushion, and a sheet 13 of a front material serving as the front portion of the bottom member of the slippers.
The foam sheet 11 made of an ethylene-vinyl acetate copolymer is preferably a closed-cell foam, and the thickness of the sheet is preferably about 2.0 to 5.0 mm. The closed-cell foam has a higher cushioning property than the open-cell foam, and water does not enter the inside of the foam from the bottom of the slippers.

  Although the material of the flexible foam sheet 12 which becomes a cushion is not specifically limited, A urethane sponge is easy to use. The thickness of the flexible foam sheet 12 is preferably about 2.0 to 3.0 mm. Since there is a foam sheet 11 made of ethylene vinyl acetate copolymer at the bottom, the thickness of the flexible foam sheet 12 is sufficient even at this level, and the comfort does not deteriorate.

The sheet 13 of the front material, which is the front part of the bottom member of the slipper, is in contact with the sole when the slippers is worn, so non-woven fabric, woven fabric, etc. are preferable because they have good feel. It may be a resin film or sheet.
In the present invention, on one side of the flexible foam sheet 12 serving as a cushion in the bottom member of the slipper, the sheet 13 of the front material serving as the front portion of the bottom member of the slipper is laminated. The foam sheet 11 made of ethylene vinyl acetate copolymer is laminated on the opposite side of the flexible foam sheet 12. Although the flexible foam sheet 12 is laminated with the foam sheet 11 and the sheet 13 made of ethylene vinyl acetate copolymer, either sheet 11 or 13 may be laminated first.

  Ease of winding of the laminated sheet if, after laminating the two sheets, winding up the laminated sheet and then laminating the other sheet to the opposite side of the flexible foam sheet 12 From the point of view, it is preferable to first laminate the sheet 13 of the front material and the flexible foam sheet 12 to be a cushion, and then laminate the foam sheet 11 made of ethylene vinyl acetate copolymer. Preferably, three sheets can be laminated continuously.

The lamination in the present invention is performed by dry lamination or hot melt lamination. Although dry lamination is a lamination using a solvent, in the present invention, dry lamination is suitable because it is not a film but to laminate three different types of sheets having a thickness.
Although hot melt lamination has the advantage of being able to be carried out in a small apparatus, the adhesive strength is somewhat inferior to dry lamination. However, since the slipper of the present invention is not supposed to be used for a long time, three sheets may be laminated by hot melt lamination.

As shown in FIG. 3, the back member 2 is made of a flexible foam 21 and a front material 22, and both 21 and 22 are laminated by lamination. The edge of the back member 2 is attached to the bottom member 1 with the foam body 21 of the back member 2 facing the front material 13 of the bottom member 1. Although the method of attachment is not particularly limited, it is preferable because sewing with a sewing machine is strong. In addition, since the flexible foam 21 is attached to the inside (that is, the side that contacts the foot when wearing slippers), it is comfortable to wear.
Nonwoven fabric, woven fabric, knitted fabric, film, etc. can be used for the front material 22 of the back member 2. The front material 22 of the back member 2 may be the same as the front material 13 of the bottom member 1, but another material may be used in consideration of design and the like.

  As mentioned above, the slipper of this invention is manufactured by attaching the back member 2 to the bottom member 1 which consists of a laminated body 10. FIG. That is, the flexible foam 12 in which the bottom member 1 of the slipper is a cushion, the surface material 13 in the bottom of the bottom member 1 of the slipper laminated on one side of the flexible foam 12, and the flexible foam 12 The bottom member 1 of the slipper is composed of a flexible foam 12, a surface material 13 and a foam 11 of polyvinyl acetate copolymer. It is cut into the shape of the bottom member 1 of the slipper in the form of a laminate 10 in which three layers are laminated, and the slipper attached to the back material 2 of the slipper is obtained on the front material side 13 of the bottom member 1 of the slipper .
