Abstract

(57) [Abstract] [Purpose] E flute One side of the insole made of corrugated cardboard is bonded as a set so that it does not come apart. [Structure] Apply adhesive to the top of one insole member,
This step top and the step valley of the other insole member are in contact with each other so as to be separably bonded to each other to form a pair of insoles. Just before use, separate the left and right hands and lay them in your shoes.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disposable insole made of single-sided corrugated board as a material.

[0002]

[Prior art]

 Shoe insoles using single-sided corrugated board have already been commercialized, and some applications for utility model registration have been made (for example, Japanese Utility Model Publication No. 3-30007 and Japanese Utility Model Publication No. 5-68005). In this way, the insole made of single-sided corrugated board is "disposable", "it does not contain plastics so there is no danger of generating harmful gas", "recyclable", etc. Has achieved. However, since it is made of single-sided corrugated board, it remains bulky and easily bent, and the packaging work and its space factor remain a problem.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention is intended to provide an insole with a simple packaging work and an improved space factor without changing the structure of the one-sided cardboard insole.

[0004]

[Means for Solving the Problems]

 As a result of earnest studies to solve the above problems, the present inventor found that if the flute (step) faces of a pair of left and right insole members face each other and the step peaks and step valleys contact each other. We have found that the packaging efficiency, that is, the space factor, improves. The present invention is based on this finding.

[0005]

【Example】

 Hereinafter, the insole of the present invention will be described in detail with reference to the drawings, but it goes without saying that the present invention is not limited thereto.

FIG. 1 illustrates a side view of the insole of the present invention, which is a pair of left and right, that is, one pair. When the left insole member 10 and the right insole member 20 are peeled off and separated, a pair of insole members as shown in the plan view of FIG. 2 is obtained. FIG. 3 is an enlarged cross-sectional view of the main part of FIG. The left insole member 10 is composed of a first liner 12 and a first corrugated core 14, and the first corrugated core 14 has a step peak 16 and a step valley 18. Similarly, the right insole member 20 is composed of a second liner 22 and a second corrugated core 24, and the second corrugated core 24 has a peak 26 and a corrugation valley 28.

If the step peaks and step troughs of the left insole member 10 and the right insole member 20 are simply brought into contact with each other, they will not be one set but will be separated. This is unavoidable because it is made of single-sided corrugated board. Therefore, in the present invention, as shown in FIG. 3, the insole members 10 and 20 on the left and right are bonded together by partially using the adhesive 30 to form one set. It is inconvenient if the entire surface of the fruit is pasted because it cannot be separated during use.

To apply the adhesive to the top of at least one insole member, use a roll coater or the like before cutting the insole member, that is, in the state of a single-faced corrugated sheet (usually rectangular). Is preferred. By doing so, rather than applying an adhesive to the insole member itself, cutting is performed in the bonded state, so that the cut surfaces on the left and right completely match. In some cases, the adhesive may be applied to both tops of the steps, but it is easy to control the adhesive to be applied to only one side in order to make the content too strong. Needless to say, the adhesive may be applied in a streak shape. The coating method is not limited to the roll coater, and other methods such as a spray method can be applied.

The adhesive may be applied in the form of a corrugated board web. For example, an adhesive may be applied to the corrugated top of one corrugated board web in-line with corrugated board production, and this may be bonded to the other corrugated corrugated web.

It is preferable that the amount of the adhesive is small and the concentration thereof is low. In the case of a roll coater, the coating amount is usually about 5 to 15 μm (μm), so that the solid content of the adhesive is preferably about 10 to 20% by weight. If the amount of adhesive applied is too large, the adhesive strength will be too strong, making it difficult to remove.

The type of adhesive is preferably an aqueous emulsion type or a water-soluble adhesive, for example, a styrene-maleic acid resin emulsion. Although it is sticky, it is not preferable because it may give discomfort during use.

The shoe insoles made in this manner are stacked on one another on the left and right, and stored in a cosmetic box or the like for distribution. When used, the left and right sides can be separated and laid inside the shoe, and after use they can be discarded as recyclable waste. .

[0013]

[Effect of device]

 Since the left and right pairs of the insole of the present invention are separably bonded to each other, the space factor is improved, which is convenient for distribution, and the left and right pairs are always one pair so that the left and right pairs can be packed together. The advantage is that the numbers will definitely match. In addition, the adhesiveness has the advantage that it does not warp or bend like an insole member with exposed single-sided corrugated board and has a beautiful appearance. Further, in the cutting or punching process, one set of right and left is processed in one process, so that the efficiency is doubled as compared with the conventional cutting process of the insole.
