Abstract

(57) [Summary] [Purpose] To provide an inexpensive insole with good usability. [Structure] A pair of left and right insoles, wherein a part of the inner edge or the outer edge of the pair of insoles is connected by a cutting line 10 that can be easily cut off.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an insole.

[0002]

[Prior art]

 At present, the insoles on the market are made for the left and right shoes using breathable material with clear front and back. Regarding sizes, there are cases where different sizes are manufactured and consumers choose it, and cases where a certain size is used for both.

[0003]

[Problems to be solved by the device]

 Therefore, when using it, it is necessary to distinguish between the front and back and the left and right, and it is very careful and sometimes mistaken. It may also be dissipated during storage. On the other hand, if different sizes are manufactured, the manufacturing cost will increase accordingly. In addition, it is necessary to cut a product of a certain size according to its own size, which is troublesome. Since the insole is a consumable item, it is absolutely necessary that it be inexpensive and last long. The present invention addresses such a problem, and an object of the present invention is to provide a shoe insole that is comfortable to use at low cost.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a sock insole characterized in that a part of the inner edge or the outer edge of a pair of left and right sock insoles are connected by a cutting line that can be easily cut.

[0005]

[Action]

 By taking the above means, the cut line portions may be separated to be used separately on the left and right sides, or the cut line may be left as it is and the left and right portions may be folded back to be used as two sheets.

[0006]

【Example】

 1 and 2 are plan views of a shoe insole according to the present invention. In the present invention, a part of the inner edge or the outer edge of a pair of left and right insoles A is connected by a tear line 10 that can be easily cut. Of. Since such an insole A can be easily formed by press-cutting using a mold, even if the left and right ones are connected to each other, the processing cost is almost unchanged except the material cost. The perforation line 10 is preferably a perforation line, and may be performed simultaneously in the molding process.

For the shoe insole A, a material that is inexpensive and has a good feeling of use is selected, and a single-faced corrugated board is a material that satisfies this. FIG. 3 is an enlarged cross-sectional view of a single-sided corrugated board, and the single-sided corrugated ball is one in which a liner 14 is attached to one side of a core 12 formed in corrugations. If this is applied to the insole A, an inexpensive and hygroscopic material can be obtained, and the stepped portion hits the foot, giving an appropriate stimulating feeling. FIG. 4 is a plan view of a shoe insole A made of single-sided corrugated board, but it is the same in that a part of the inner edge or the outer edge thereof is connected by a cutting line 10 that can be easily cut.

If the cut line 10 is cut, insert the left and right shoes into the left and right shoes with the steps facing up. If not cut, fold them so that the steps are on the outside and insert into the shoes. To do. Therefore, in the latter case, two pieces connected left and right are required, but the same as using double-faced cardboard, and the usability is further improved. It should be noted that although it will not be greatly displaced even if it is simply folded back and inserted into the shoe, it is more preferable if it is lightly bonded.

FIG. 5 is a plan view of the insole A in which a crush line 16 for crushing a step is inserted in a single-faced corrugated board, and FIG. 6 is an enlarged cross-sectional view thereof. By inserting the crush line 16 in this way, the step is strengthened. It also improves comfort and durability. In this sense, the crush line 16 is preferably inserted so as to intersect the step (more preferably, at a right angle to the step). The crush line 16 may be formed by a forming roller or a mold, but the latter has the advantage that it can be processed simultaneously with molding.

Next, regarding the size adjustment, there are the following two methods. FIG. 7 is a plan view of the insole A showing the first method, which is a method of forming a plurality of perforation lines 18 corresponding to large and small sizes around the connecting portion from the toe to the heel. This allows the consumer to cut (or manually peel off) the perforation line 18 according to the size of their feet. The cut line 18 may also have perforations. This method has the advantage of conforming to the shape of the foot (shoe) for each size.

FIG. 8 is a plan view of the insole A showing the second method, but this method provides the cutoff line 18 only on the heel portion. Since the shape of the insole A does not have to completely match the shape of the shoe, this can be sufficiently dealt with. This method has the advantages of low manufacturing cost and easy separation.

[0012]

[Effect of device]

 As described above, according to the insole according to the present invention, the cutoff line of the connected portion may be separated and used, or this portion may be folded and used as it is. In the former case, many can be used and it is economical, and in the latter case, durability is increased. Furthermore, if the insole is made of single-faced cardboard, it is possible to provide a product that does not dissatisfy usability at a very low cost.
