DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates includes a footwear in a bottom insole consisting of a pair of sheet forming the left-right symmetric, and methods of manufacturing such as sheet intended for the bottom insole classes in the toilet seat and footwear About.

[0002]

2. Description of the Related Art For example, a toilet seat seat detachably mounted on the left and right sides of the upper surface of a toilet seat is widely known in Japanese Utility Model Laid-Open No. 4-89097. The toilet seat sheet is formed by integrally laminating an adhesive layer on the back surface of the mat body and is cut into a symmetrical substantially crescent shape as a set of two sheets. Such a toilet seat sheet is formed by punching one sheet at a time from an original mat having a pressure-sensitive adhesive layer applied to one side thereof. When the product is sold as a product, the toilet seat sheets formed separately are realigned into a set of left and right pairs and packaged.

[0003]

However, since this type of toilet seat sheet is a set of two sheets, and is flat and substantially crescent-shaped, it is punched and cut one by one from the raw sheet before packaging. In the case of the conventional toilet seat sheet that has been set, it is troublesome to set it in a single line. Still, only one of the left and right sides may be packed in two sheets. The left and right sides differed in size and color, and the left and right design patterns became irregular. Such a situation is a problem that is common to a pair of symmetrical sheets such as slippers and insole of shoes, and is troublesome in terms of inventory management.

Accordingly, an object of the present invention is to provide a bilaterally symmetrical pair of sheets having an adhesive layer on the back surface of a mat body,
It is an object of the present invention to provide a sheet body which can be obtained in a joined state of two upper and lower sheets by utilizing the re-adhesiveness of the pressure-sensitive adhesive layer, and which can save the trouble of prior to packaging, and a method of manufacturing the same.

[0005]

In FIG. 1, a sheet body A according to the present invention comprises an adhesive layer 3 on one side of a mat body 2.
And a release sheet 10 interposed between the pressure-sensitive adhesive layers 3 of the two sheets 1.
The two sheets 1.1 are separable via the release sheet 10, but are joined via the two pressure-sensitive adhesive layers 3.3. When the two sheets 1.1 are separated, they are symmetrical. It is formed so that it becomes.

More specifically, as shown in FIG. 5, two mat webs 5a, 5a having an adhesive layer 3 integrally laminated on one side surface, and an adhesive layer of both mat webs 5a, 5a 3.
The sheet body A is punched from a web laminate 12 in which three sheets of the release sheet web 10a interposed between the three sheets are joined in three layers. Thus, the two sheets 1.1 having the pressure-sensitive adhesive layer 3 on the mat body 2 are punched and formed with the two mat raw materials 5a so that they become symmetric when separated. , Release sheet material 1
It is stamped and formed at 0a. The pressure-sensitive adhesive layer 3 may be formed by coating on the raw material mat 5a, or may be laminated and formed by integrally bonding the raw material mat 5a and a sheet constituting the pressure-sensitive adhesive layer 3 under heat and pressure.

In the sheet member A according to the first aspect of the present invention,
Means that a pair of sheets 1 and 1 has an adhesive layer 3
· 3 Ru used respectively detachably bottom insole for footwear which is to be attached via. The invention according to claims 2 to 4.

It has a lunar shape and is used as a seat for toilet seat.
Can be.

In manufacturing such a sheet body A, first, as shown in FIG.
After the adhesive 3a is applied to one side surface (upper surface) while the adhesive 3a is not cured, the scraper 7
Then, a groove 4 is formed in the adhesive 3a. As shown in FIG. 3, the grooves 4 are formed at a predetermined pitch in the width direction of the raw material mat 5 over the entire length in the longitudinal direction. Thus, the adhesive 3a is dried, and the adhesive layer 3 with the groove 4 is integrally laminated on the raw material mat 5.

Next, as shown in FIG. 4, the mat raw material 5 is slitted, and the mat raw material 5 is cut so as to be bisected in the longitudinal direction at the center in the width direction, and the half width mat raw materials 5a and 5a thus obtained are once obtained. Take up in a roll. Thereafter, as shown in FIG. 5, three half-width raw mats 5a and 5a and a raw release film 10a made of a plastic film are overlapped with each other. At this time, the release sheet raw material 10a is passed through the pressure-sensitive adhesive layers 3.3 of the upper and lower half-width mat raw materials 5a. Finally, a sheet A having a desired shape is punched out from the three-ply raw laminate 12 by a press 13 to form the same.
When the upper and lower sheets 1 and 1 are separated from each other, the sheet body A thus obtained is formed in a symmetrical form as a pair (one set) in the state of FIG. The state is maintained. As the raw mat 5, for example, a sheet formed by entanglement of polyester fibers in a felt shape can be used. In the adhesive 3a,
For example, an ecryl resin or a polyurethane resin containing a foaming agent can be used. For example, a polypropylene film can be used as the release sheet raw material 10a.

[0010]

The sheet A is wrapped one by one or several sheets with a wrapping film. The release sheet 10 is interposed during the distribution, but the upper and lower sheets 1 and 1 maintain the bonded state of the sheet A via the adhesive layers 3 and 3. When the user unpacks and uses the package, the upper and lower sheets 1.1 are separated from one end of the sheet A. At this time, since the release sheet 10 remains attached to the one sheet 1, the release sheet 10 is subsequently peeled off from the one sheet 1. The release sheet 10 is removed. The separated sheets 1.1 have a symmetrical shape as shown in FIG. 6 (a), and are attached to the toilet seat sheet so as not to be inadvertently peeled off via the adhesive layer 3 on the upper left and right sides of the toilet seat when used as a toilet seat sheet. it can. Since the pressure-sensitive adhesive layer 3 has re-adhesiveness, the mounting surface of the sheet 1 can be easily peeled off, and can be mounted again after washing if necessary.

[0011]

The sheet A obtained by the present invention is
Since the upper and lower sheets 1 and 1 are simultaneously punched and formed under a polymerization state with the release sheet 10 interposed therebetween, and are maintained in a three-layer joined state via the adhesive layers 3 and 2, two sheets are formed. The sheets 1.1 are always of the same size and are a pair of left-right symmetrical ones. Therefore,
When managing inventory and packaging, it is convenient to handle both sheets 1.1 as a set of two sheets at all times, and the left and right sheets 1.1 are only one of two sheets, or there is a difference in shape between them. There is no room for irregularities to occur.

In addition, according to the method of the present invention, one sheet of the raw mat 5 is divided into two, and the half-width mat raw sheets 5a and 5a are stacked into three sheets with the release sheet raw 10a interposed therebetween. Since the body A is punched, it is possible to surely prevent the set of sheets 1.1 from being left and right with different colors and causing inconsistency in the design and pattern. Furthermore, when the adhesive layer 3 is applied and formed on the mat stock 5, if the grooves 4 are formed in a streak shape, the applied amount of the adhesive 3 a is reduced by the interposition of the grooves 4, and the manufacturing cost of each sheet 1 is reduced. Contribute to In addition, there is an advantage that when the two sheets 1 are separated, they can be easily separated from the edges by using the open ends of the grooves 4.

[0013]

And a pressure-sensitive adhesive layer 3 laminated on the back surface of the pressure-sensitive adhesive layer. On the outer surface of the pressure-sensitive adhesive layer 3, grooves 4 are formed so as to extend substantially in the vertical direction in the figure. The sheet 1 is a pair of left and right symmetrical ones, and can be detachably attached to the left and right sides of the toilet seat via the adhesive layer 3, and the adhesive layer 3 does not slip off even when the toilet seat is standing. The adhesive layer 3 is adjusted so that even if the mat body 2 is strongly pressed against the toilet seat in the summer, the adhesive layer 3 does not displace and adhere to the toilet seat surface.
The adhesive layer 3 is made of a material that can be repeatedly adhered to the seat 1 after the sheet 1 is once peeled off from the toilet seat, washed, and then attached again.

The manufacturing process of the sheet 1 will be described. As shown in FIG. 2, a 180-cm wide roll-shaped matte material 5 having a colored or patterned pattern on its outer surface is fed out in the direction of arrow P, and the back side thereof is The pressure-sensitive adhesive 3a discharged from the die 6 is uniformly applied on the entire surface of the raw mat 5 with the surface facing upward. The adhesive 3a is mainly composed of an acrylate copolymer containing a foaming agent, and a groove 4 is formed on the adhesive 3a by a scraper 7 while the adhesive 3a on the raw mat 5 is uncured. The scraper 7 has a large number of claws 7a projecting downward at a constant pitch in the front-rear direction. By bringing the lower end of each of the claws 7a into contact with the adhesive layer 3, the scraper 7 is placed on the adhesive layer 3 as shown in FIG. A groove 4 is formed along the entire length in the longitudinal direction at a specified pitch in the width direction of the raw material mat 5, and the surface is smoothed while scraping off the adhesive 3a in the portion of the groove 4.

Subsequently, the adhesive material 3a is heated and dried at a temperature of 180 ° C. by passing the raw material mat 5 through an oven 9 to foam it, and the adhesive layer 3 is integrally laminated on the raw material mat 5. Next, as shown in FIG. 4, the center of the width direction of the raw mat 5 is cut by a slitter so as to be bisected in the longitudinal direction, and both ends of the raw mat 5 are cut and removed.
