Description

[Detailed Description of the Invention] This invention relates to a storage book for documents, etc., and particularly to a storage book that can store documents whose width is twice the width of the storage book.

Conventionally, a required number of bag-shaped storage plates made of thermoplastic synthetic resin film and approximately the same size as the cover plate are superposed on the inner surface of a bifoldable cover plate made of thermoplastic synthetic resin, and A storage book for documents and the like is known in which the central part of the overlapping storage plate is heat-sealed to the inner surface of the back of the cover plate along a vertical line so that it can be folded into two.

However, in the known device, the size of the storage plate is the same as the size of the cover plate, so the maximum size of documents that can be stored is limited to half the size of the cover plate.

In other words, when the cover plate and storage plate are Ba, the maximum size that can be stored is 85 plates since the storage plate is stacked on top of the cover plate and then fused at the center. Ta.

Therefore, in order to be able to store documents that are twice the width, it is necessary to use a cover board and storage board that are twice the width, so new cover boards and storage boards must be manufactured. The disadvantage is that the completed storage book is large, making it inconvenient to store and transport.

This idea allows documents with twice the width to be stored without changing the size of the cover board or storage board.
The present invention will be explained below based on the embodiment shown in the drawings. 1 is a relatively thick thermoplastic synthetic resin board made of polypropylene or vinyl chloride, and the cover board is foldable in two at the back 1'; 2 is made of an extremely thin transparent film made of thermoplastic synthetic resin, and has a bag-like shape with an opening 2' at the upper edge, and is slightly smaller than the cover plate 1. It is suitable for storing documents of, for example, 84 editions. This storage board 2 is placed such that one end thereof is located at the center of the cover board 1 and is oriented in one direction, and the other end is located in the center of the cover board 1. The storage boards are placed so that one end thereof is located at the center of the cover board 1 and oriented toward the other side, and the one end parts of the storage boards are stacked, and in this way, the cover board 2 is sequentially stacked. One end of each sheet is stacked alternately as shown in FIG. 2, or a plurality of sheets are oriented toward one side of the cover plate 1 and a plurality of sheets are oriented toward the other side of the cover plate 1, as shown in FIG. 4. A plurality of storage plates 2 are stacked together with their one side ends together, and in this state, one end of all the stacked storage plates 2 is simultaneously heated and melted onto the back 1' of the cover plate 1. This is the third time I have arrived.

The drawing shows the most preferred embodiment in which the upper and lower ends of the storage board 2 are heat-sealed 3 with only a small portion remaining, and the upper and lower portions of the storage board 2 that remain without being heat-sealed to the back 1' of the cover board 1 are This shows the case where the ends are heat-sealed 4 between the storage plates 2 as shown in FIG. 3, and in this way, as shown in FIG. 1,
Approximately half of each storage board 2 constitutes a storage book that protrudes from both sides of the cover board 1, respectively.

However, when storing documents after storing them in the storage board 2 through the upper edge opening 2', first fold back the hand portion of the storage board 2 that protrudes from the side edge of the cover board 1, and then fold back the cover. It is formed to a size corresponding to half of the plate 1.

After all the storage plates 2 have been folded in this way, the cover plate 1 can be folded in half to a size convenient for storage and transportation.

The storage board is usually made by extruding a long transparent film strip into a cylindrical shape and separating it sequentially by welding and cutting to match the vertical dimension of the cover plate.The left and right side edges are closed, and the top and bottom edges are sealed by welding and cutting. After creating a storage blank, the upper edge sealing part is cut to form a bag shape, and in this application,
The storage plate configured in this way can be used, and in this case, when configured into a storage book, the welded and cut portion is located only on the lower edge, giving it a good appearance. It has the advantage that the long transparent film strip and the welding/cutting device can be used as they are, and as shown in the embodiment, the upper and lower ends of the storage plate 2 are not fused to the cover plate, and the storage plate 2 is When they are heat-sealed together, it is possible to easily store and pull out documents, etc., and it is also useful for reinforcing the storage plate 2 when it is turned over.

This invention has the advantage of being constructed as described above, and can be reduced to approximately half its size when not in use, making it extremely convenient for storage and the like, as well as being easy to transport.

[Brief explanation of the drawing]
