Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present application relates to an insertion file configured to store paper sheets such as documents and to allow the contents of the paper sheets to be seen through the surface.

Prior art and its problems Conventionally, the left and right wings of an opaque synthetic resin base sheet are sandwiched between transparent synthetic resin top sheets folded in half, and their upper and lower edges are welded together, or the above base sheet is Both the left and right wings are inserted into a flat cylindrical surface sheet made of a transparent synthetic resin sheet, and their outer edges are welded together, so that both the left and right wings of the base sheet are coated.
A plurality of 2-page storage sheets each having a bag-like portion opened on the inside for storing paper sheets such as documents are superimposed on the inner surface of the file cover, and the central binding portion of the base sheet is attached to the back of the file cover. An insert file which is integrally welded to the left and right bag portions is well known and widely used, and this insert file has the advantage of being able to store two-page paper sheets across the left and right pouch-like portions.

By the way, this type of insertion file is generally
Since the paper is stored upright on a bookshelf, the two-page paper sheets stored across the left and right bag-like parts are placed down to the lower edge of the bag-like part. Furthermore, when opening the insert file and turning the pages, as shown in FIG.
It is placed in a state where it is raised above the central binding part. Therefore, since the paper sheet a has descended to the lower edge of the bag-shaped part b and the central binding part of the paper sheet a is raised from the surface of the base sheet c, when turning the page,
The cuff of clothing often comes into contact with the central lower edge (front edge) of paper sheet a, and there is a risk that the central lower edge of sheet a may be damaged, and if the sheet is an important document, It had become a big problem.

OBJECTS, EMBODIMENTS, AND AFFECTS OF THE INVENTION The present application aims to improve the above-mentioned deficiencies of the conventional products. A bifold-shaped top sheet or a flat cylindrical top sheet 3 made of a transparent synthetic resin sheet is covered, and the upper and lower edges or outer edges of the top sheet 3 are welded to each other on both the left and right wings of the base sheet 2. This storage sheet is formed by forming bag-like portions 4 that open on the inside, and the present application is directed to the lower edge of the base sheet 2 at the intermediate binding portion 5 of the bag-like portions 4, 4 that face each other on the left and right wings of the storage sheet 1. , a trapezoidal tongue piece 6 is extended, and the storage sheet 1 configured in this way is
As in the past, it is integrally welded 8 to the back of a file cover 7 made of a slightly larger synthetic resin.

Note that the extended length of the tongue piece 6 is the same as that of the file cover 7.
The length is set to almost reach the bottom edge of the .

However, in the unfolded state, as shown in FIG. However, due to the extension of the tongue piece 6, the paper sheet a
The situation is the same as if the central lower edge of the pouch 4 had moved upward from the lower edge of the pouch 4 in a manner corresponding to the extended length of the tongue piece 6, and as a result, when the page was turned, the cuffs of the clothes were Before contacting the central lower edge of leaf a, the tongue piece 6 comes into contact with the peripheral edge, and therefore there is almost no possibility that the cuff of the garment will come into contact with the central lower edge of paper sheet a.

Effects of the Invention Since the present application is constructed as described above, even if a paper sheet such as a two-page document is stored across the left and right pouch-like portions, the central lower edge of the paper sheet will not be damaged. It has the advantage that the pages can be turned without any trouble, and that the lower edge of the back of the file cover is reinforced by welding the tongue piece when the file is stored upright on a bookshelf or the like.

[Brief explanation of drawings]

The drawings show an embodiment of the present application, and FIG. 1 is a plan view of the opened book, FIG. 2 is a partially cutaway plan view of the storage sheet, FIG. 3 is a partially enlarged view, and FIG. FIG. 2 is a partially enlarged view of a conventional configuration corresponding to the figure. In the figure, 1 is a storage sheet, 2 is a base sheet, 3 is a top sheet, 4 is a bag-shaped portion, 5 is a central binding portion, 6 is a tongue piece, 7 is a file cover, and 8 is a welded portion.

Claims (1)

[Claims] 1. A two-page base sheet made of an opaque synthetic resin sheet is formed with a top sheet made of a transparent synthetic resin sheet on both sides of the wings, and a bag-shaped portion that opens on the inside is formed, and a bag-shaped portion is formed on the lower edge of the center of the base sheet. A storage sheet is constructed by extending tongue pieces, a plurality of these storage sheets are superposed on the inner surface of a file cover made of synthetic resin, and a central binding edge portion including the tongue pieces of the base sheet is integrated with the file cover. An insert file characterized by being welded.
