Description

DETAILED DESCRIPTION OF THE INVENTION The industrial field of application relates to a 7-isle insert configured to store paper sheets and to allow the contents of the paper sales business to be seen through the surface.

PRIOR ART AND PROBLEMS Conventionally, an opaque synthetic resin base sheet is folded in half and a transparent synthetic resin top sheet is inserted, and the top and bottom sheets are welded together, or the base sheet is It is inserted into a flat cylindrical surface sheet made of a transparent synthetic resin sheet, and their outer edges are welded together.
on both sides of the base sheet.

A plurality of 1-page-sized single-sided storage sheets or 2-page-sized double-sided storage sheets that form an open bag-like part inside to store 111 sheets of documents etc. are placed on the inside of a synthetic resin file cover. At the same time as polymerization, in the former case, the binding part of the nine base sheets extends from the sapon-like part, and in the latter case, the central binding part of the base sheet is integrally melted on the spine of the file cover. The 7-isle insertion is well known and widely used, but according to this woodcutter's insertion file.

Both the base sheet and the front sheet are very thin sheets, and the oversheet and -eUiJ sheet are in a closely polymerized state, so in order to store paper sheets such as pleated 5KIIllF, it is necessary to When the mouth edge is opened, as shown in Fig. 5, the Ueda edge of the base seam hB is 1 ml;
The upper edge of the base sheet HL is often damaged due to being forcibly pulled by the upper edge, folded in a complicated manner, rolled up, and used for a long period of time or by a large opening operation. In the structure where the upper edges of the one-sided sheet b are welded to each other, the welded portion tends to be damaged.

OBJECTS, EMBODIMENTS, AND OPERATIONS OF THE INVENTION The present application aims to improve the above-mentioned conventional defects, and embodiments thereof will be described in detail below with reference to the drawings. Figures 1 and 2 show the case of two-page storage sheets on both sides. Insert it into a bifold top sheet made of a transparent synthetic resin sheet, or insert it into a flat cylindrical shape! Insert it into the first sheet (3), and connect the upper and lower edges or the outer edges to V! This is a storage sheet that is taken by forming bag-shaped portions (4) that open on the inside on both sides of the base sheet (11), and the present application describes pouch (4).

At least one of the upper and lower edges of the base sheet (3) in the intermediate binding portion of (4), preferably the upper and lower edges, is provided with a U-shaped 9
A trapezoidal cut-out recess (6) is provided, and the storage sheet (1) configured in this manner is placed on the inner surface of the file cover (7) made of slightly thick synthetic resin, as in the past. *
A sheet is polymerized, and in this state, the central binding part (5) of the storage sheet (1) is integrally welded (81) to the back of the file cover (7).
It consists of

The table and Figure 3 show the inserted files when using the lJ [large piece R storage sheet 1, etc.].

When the opening of the bag-shaped part (4) is opened to store paper products such as documents, the upper edge of the base sheet (1) and the top edge of the top sheet ( 1) The notch recess (6) is removed without applying excessive tensile force to the southern part of the upper edge.
Each JIJK is bent from the side edge of the opening li of one bag-shaped part.
& opens wide.

Effects of the Invention As described above, according to the present application, when the bag-shaped portion is opened, the upper part of the base sheet is easily bent into the notch recess, and the upper part of the base sheet is folded as in the conventional case. There is no risk of excessive tensile force being applied to the upper (G) edge of F) I# and the top sheet, there is no risk of damage, and the bag-shaped portion can be opened easily. Moreover, since the opening of the bag-shaped part is wide open, it has the advantage of being convenient for putting in and taking out paper sheets such as documents.

[Brief explanation of drawings]

The drawings show an embodiment of the present application, and FIGS. 1 and 3 are plan views of the book in an open state, FIG. 2 is a partially cutaway plan view of the storage sheet, and FIG. . Partially enlarged plan view, fang 5 is in the figure corresponding to figure 4 (
1), (1)' are storage sheets, (2) are base sheets, (3
) is the bag surface sheet 14) is the bag-shaped part 2 (5) is the binding part, (6)
(7) is the file cover, (8) is the welded part.

Claims (2)

[Claims] (1) On both sides of an opaque synthetic resin base sheet, a transparent synthetic resin top sheet is used to form a bag-like part that opens on the inside, and a base sheet that extends inward from the bag-like part. A storage sheet is constructed by providing a notched recess on at least one of the upper and lower edges of the binding portion of the sheet, and a plurality of these storage sheets are superimposed on the inner surface of a synthetic resin file cover to form the binding portion of the base sheet. An insertion file characterized by being integrally welded to the file cover. (2) The insertion file according to claim 1, which is composed of a two-page-sized storage sheet for both wings, and has a cutout recess extending over both wings.
