がある。2. Description of the Related Art As a plastic case having a transparent window that has been generally used in the past, a paper box is provided with a window hole, and a transparent plastic film or sheet is adhered from the inside around the window hole. There are a transparent plastic film attached to the entire outer surface of the paper box, a transparent plastic sheet with a window portion left for printing, and a plastic case having a see-through window.

ために紙の厚みを大きくするため窓孔周囲において紙の
断面が外から見えて美しい箱とならず高級感が出ない。In a paper box in which a transparent plastic film or sheet is adhered from the inside around the window hole, the thickness of the paper is increased to maintain the strength of the box, so that the cross section of the paper around the window hole is visible from the outside and is beautiful. It does not look like a box and does not give a high-class feel.

チックフイルムに皺が多発する恐れがある。A box in which a transparent plastic film is adhered to the entire outer surface of the paper box has a glossy appearance of the plastic, which makes the outer surface feel cold, and a difference in shrinkage between the plastic film and the paper due to humidity or the like is large. Wrinkles may occur frequently on the part of the plastic film.

フト感を出したい商品には採用出来ない問題がある。In the case where the entire box is composed of printed plastic sheets, the cost of printing on the plastic sheets tends to be high, and the yield tends to be significantly inferior to that of paper, and the gloss of the plastic tends to appear on the outer surface and feel cold. There is a problem that it can not be adopted for products that want to give a soft feeling.

基づいて説明する。SUMMARY OF THE INVENTION The present invention has improved appearance and cold feeling which were problems of the prior art. Paper having a soft feeling, transparency, waist strength, and dimensions against humidity. By combining a plastic sheet with advantages such as stability, a transparent and soft plastic case is obtained, and a paper with a window hole and a plastic sheet are combined with a hot melt adhesive layer. It is a blank sheet formed by stacking through, punching into a case expanded shape, and laying folding ruled lines, which will be described below with reference to the accompanying drawings.

が好ましいが印刷をほどこしてもよい。As the plastic sheet 2, a single or composite sheet made of hard or semi-rigid polyvinyl chloride, polystyrene, polypropylene, polyethylene terephthalate or the like can be adopted, and the wall thickness is 0.1 to 1.0 mm.
Some of them have high rigidity, the strength of the assembled plastic case is increased, and wrinkles do not occur in the window portion, so that they can be preferably used. A transparent plastic sheet is preferred but may be printed.
【0011】紙1とプラスチックシート2とを積層する
ためには、例えば図3〜図6に示す工程が採用できる。In order to stack the paper 1 and the plastic sheet 2, the steps shown in FIGS. 3 to 6 can be adopted.

ある。That is, first, as shown in FIG. 3, a hot melt adhesive 3 is applied to the back surface of the paper 1 on which printing 13 is applied,
Once cooled and cured, the paper 1
Is punched out to form the window hole 11, and then the paper 1 is heated and pressed to the transparent plastic sheet 2 via the hot melt adhesive 3 as shown in FIG. This has an advantage that the adhesive layer can be formed in a necessary portion without excess or deficiency, and the step of punching the paper 1 and providing the window hole 11 is easy because the adhesive layer is cured.

るので効率的である。Then, as shown in FIG. 6, the laminated body of the paper 1 and the plastic sheet 2 in a bonded state is punched out into a developed shape of a plastic case, and a folding ruled line 4 is laid to manufacture a blank sheet. Here, the bonding step is efficient because the paper 1 and the plastic sheet 2 which are still long can be used.

形成する方法で良好に加工できる。Here, the window hole 11 is punched in the paper 1, the laminated body is punched in the expanded shape of the plastic case,
In order to lay the folding ruled lines 4 into a blank sheet, as shown in FIG. 4, punch out an outline shape with a Thomson die 6, 61 or the like used in general paper or plastic sheet processing, and at a predetermined depth. Good processing can be performed by a method of pressing to form the bent ruled line 4.

When assembling the plastic case as shown in FIG. 7, the glue margin 5 is adhered to the other end 51 to form a tubular shape with the layer of the paper 1 of FIGS.
It is preferable to fold and assemble the paper 1 because the soft feeling of the paper 1 is exposed. Further, since the transparent window 11 has a step corresponding to the thickness of the paper 1 and the surface of the plastic sheet 21 is lowered, scratches and the like during transportation are less likely to occur.

Printing 13 is performed on the high-quality processed paper of 2 , and an ethylene-vinyl acetate-based hot melt adhesive is applied as an adhesive layer to the surface opposite to the printed surface and cooled, and one day later, as shown in FIG. Punch the window hole 11 in the position with Thomson type 6,
As shown in FIG. 5, an amorphous polyethylene terephthalate sheet having a wall thickness of 0.25 mm is continuously pressed between the heating roll 7 (diameter 200 mm) at 120 ° C. and the receiving roll 71 on the side of the paper 1 to achieve complete adhesion. It was

This blank sheet is formed into a tubular shape by adhering the glue margin 5 to the other end 51 so that the layer of the paper 1 is on the outer surface, and then bent from the folding ruled line 4 to form a plastic case as shown in FIG. When assembled, a soft feeling was obtained as a whole, and the plastic sheet 21 which became the see-through window had a beautiful finish without wrinkles.
