Abstract

(57) [Summary] [PROBLEMS] To provide a high-quality sheet-like holder which is harmless to the environment, easy to manufacture, and high in quality. SOLUTION: In a holder composed of a pair of rectangular sheets 1 and 1 superposed in the same shape and having peripheral edges of each of the sheets 1 and 1 except one side thereof fixed via a spacer 5, polyethylene terephthalate ( PET)
Of at least one of the peripheral portions of the rectangular sheets 1 and 1 are provided with folded portions 4 on three sides thereof, and the peripheral portions of the rectangular sheets 1 and 1 are fused together with the folded portions 4 interposed therebetween. It was done. Since it is formed from PET, it can be collected and recycled. Since the folded portions 4 and 4 are provided integrally with the rectangular sheets 1 and 1, no displacement occurs when the sheets 1 and 1 are fixed to each other. Since the peripheral portions are fused together, no adhesive is required.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a holder for storing sheets, such as documents, which is suitable for recycling and can be manufactured to a stable quality.

[0002]

[Prior art]

 As a document holder, for example, there is a holder made of a pair of rectangular sheets superimposed in the same shape. In this holder, the peripheral portions of the respective sheets are fixed to each other via a spacer except one of the sides, and a pocket having an opening at the non-fixed side is formed so that a document can be taken in and out freely. It is designed to be stored.

The spacer is made of a shaft material having a length corresponding to each side of the rectangular sheet, and is fixed by an adhesive. As a material of the holder, a resin such as PVC (polyvinyl chloride) is mainly used.

[0004]

[Problems to be solved by the invention]

 However, the above-mentioned holder has a problem that it cannot be discarded as it is because toxic substances such as chlorine gas and dioxin are generated from PVC when incinerated.

In addition, since the spacer is a separate member from the rectangular sheet, a positional shift may occur when the sheets are fixed to each other, resulting in poor workability, and the need to apply the adhesive evenly. For example, there was a problem that not only did the finished product become poor due to unevenness, but also its strength was deteriorated, so that a stable high quality product could not be obtained.

Accordingly, an object of the present invention is to provide a high-quality sheet-like holder which is harmless to the environment, easy to manufacture, and high in quality.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention relates to a holder comprising a pair of rectangular sheets superimposed in the same shape, and fixing the peripheral portions of each sheet via a spacer except for one of the sides. At least one of the peripheral portions of the rectangular sheet made of polyethylene terephthalate (PET) was provided with a folded portion at three peripheral portions, and the peripheral portions of the rectangular sheets were fused together while sandwiching the folded portion. It is.

Since the holder is made of PET, it can be collected and recycled, and does not generate toxic substances such as chlorine gas or dioxin due to its molecular structure when incinerated.

In addition, since the folded portion is provided integrally with the rectangular sheet, no displacement occurs when the sheets are fixed to each other, and the peripheral portions are fused to each other, so that no adhesive is required, and high quality is achieved. Products can be obtained.

[0010]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The holder shown in FIG. 1 is composed of a pair of transparent PET rectangular sheets 1, 1 superposed in the same shape, and the peripheral portions of the sheets 1, 1 are fused together in a rack shape except for one long side. It is. As shown in the figure, the one side that is not fused serves as a slot 2 for a sheet-like material s such as a document.

As shown in FIGS. 2 (a) and 2 (b), a large number of recesses 3 are formed in the peripheral portion and are continuous in the longitudinal direction. A spacer 5 composed of folded portions 4 and 4 provided in the portion is provided. Each of the rectangular sheets 1 and 1 has a thickness of about 0.4 mm. As shown in FIG. 3, each corner is cut diagonally, and a groove having a depth of about 0.2 mm extends along the outer periphery. 6 are provided on the three peripheral edges.

In order to manufacture the holder, first, as shown in FIG. 4A, the periphery of each of the sheets 1 and 1 is folded from the groove 6 to the same surface side to form the folded portions 4 and 4. The sheets 1 and 1 are overlapped in the same shape with the folded portions 4 and 4 sandwiched therebetween.

Subsequently, as shown in FIG. 4B, when the overlapping portions of the folded portions 4 and 4 are fused with a high-frequency welder having a toothed edge w, the folded portions 4 and 4 are integrally formed. The spacers 5 are formed, the rectangular sheets 1 and 1 are fixed to each other, and a holder having a peripheral portion formed in a rack shape by a large number of concave portions 3 is completed. The folded portion 4 may be provided on only one of the rectangular sheets 1 as shown in FIG.

Since the holder is made of PET, it can be collected and recycled, and does not generate toxic substances such as chlorine gas or dioxin due to its molecular structure even when incinerated.

Further, since the folded portion 4 is provided integrally with the rectangular sheet 1, no displacement occurs when the sheets 1, 1 are fixed to each other, and the peripheral portions are fused to each other. Good quality products can be obtained.

Further, by forming the fused portion in a rack shape, the fixing area between the rectangular sheets 1 and 1 is increased, so that the strength and the design are excellent.

[0017]

[Effect of the invention]

 As explained above, the sheet holder according to the present invention is made of PET, so that it can be recycled when collected, and does not generate toxic substances such as chlorine gas or dioxin due to its molecular structure when incinerated. Contribute to environmental protection and resource saving.

[0018] Furthermore, since the folded portion is provided on the rectangular sheet and the peripheral edge portion is fused together with the folded portion, no misalignment occurs when the sheets are fixed to each other, the sheet can be easily manufactured, and the workability is improved. At the same time, the fixing area between the rectangular sheets is increased, and the strength and design are improved, so that a stable high-quality product can be obtained.
