Description

[Detailed description of the invention] The present invention provides a pocket for organizing paper sheets such as negative film, and more specifically, it is possible to easily store and take out paper sheets, prevent the stored sheets from falling out, and The present invention relates to a pocket that allows for good page turning when the book is bound into an album.

Conventionally, various pockets have been proposed that are convenient for organizing paper sheets such as negative film.

For example, the one shown in Figure 2 is a pocket for negative film, in which one synthetic resin sheet 1 is folded over so that the back sheet 2 partially protrudes from the top sheet 3, and then both sheets 2 and 3 are integrated. and at appropriate intervals (negative film A
The storage pocket portion 4 is defined by adhesion or heat welding 5 at intervals satisfying the width of .

However, at the entrance of the pocket section 4, both sheets 2
The thermal welding 5 of 3 and 3 is not completed completely to the end but is interrupted midway.

When storing the negative film A in such a pocket, the top sheet 3 at the entrance of the pocket section 4 is turned over and stored, but even if it is easy to store, it is also easy to fall off.

Since the entrance is always open as shown in the figure, it is inevitable that the negative film will become dirty or dusty from this point.

Furthermore, when an album is bound, there is a drawback that page turning cannot be carried out well due to the difference in level between the front sheet and the back sheet.

The present invention was completed in order to eliminate the drawbacks of the conventional pocket for organizing paper sheets, and its feature is that the protruding part of the back sheet in the conventional pocket has an end surface on the end surface of the top sheet. This means that the sheets are bonded or thermally welded together in contact with each other.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

In FIG. 1, reference numeral 11 is a synthetic resin sheet made by overlapping cylindrical sheets, and the top sheet 12 is cut at a position that satisfies the length of the negative film A to be stored, and is separated from the storage area 13. It is divided into a prevention section 14.

Furthermore, a storage pocket 16 is defined in the storage area 13 by gluing or thermally welding the top sheet 12 and the back sheet 15 integrally at appropriate intervals (an interval that satisfies the width of the negative film A). There is.

The applicable range of the thermally welded portion 17 is such that it can be opened and closed freely by pinching at least the tip portion as shown in B, similar to the conventional pocket.

With this configuration, the negative film A can be easily stored, and the stored negative film A can be easily taken out.

The corresponding piece sheet is fixedly held 18 in the drop-off prevention part 14 by adhesive or heat welding so that the folded part does not open.

The fixation 18 may be located along the folding direction as shown in the figure, or may be a continuous seal in the direction perpendicular to the folding direction.

The synthetic resin sheet used in the present invention does not need to be provided in the form of a cylindrical sheet, as its initial shape is as described above, but may be provided in the form of, for example, a single sheet folded as appropriate, or a combination of two sheets. There is no problem with that either.

In short, it is only necessary that the piece sheet be fixed to the fall prevention part in contact with the end surface of one sheet at the entrance of the storage area.

In addition, such a contact sheet may be provided by folding the back sheet as described above, or may be provided as a separate contact sheet.

Examples of the synthetic resin sheet include ordinary polyethylene films (high pressure method, medium pressure method, low pressure method), polypropylene films (stretched or unstretched), other plastic films, or composite films thereof.

Although the above specific example has been described with respect to a pocket for organizing negative films, it must be understood that the present invention can also be applied to albums for organizing similar paper sheets such as photographs, stamps, and business cards.

In the invented pocket configured in this way,
The negative film can be easily stored by pinching the cut end of the top sheet and opening it, and can be completely stored by closing it after storage.

For this reason, there is no dirt or dust build-up that occurs in conventional pockets, and the problem of negative films stored therein falling out during sorting is eliminated.

Furthermore, even when removing stored negative film,
This can be easily done using the operations described above.

Moreover, since the drop-off prevention part is composed of two sheets like the storage area, the thickness of the pocket is the same as a whole, making it easy to turn the pages when bound, and the appearance of the bound album is also good. It can be said to be a thing.

[Brief explanation of the drawing]

FIG. 1 is a perspective view showing an example of the pocket of the present invention, and FIG. 2 is a perspective view showing an example of a conventionally known pocket for organizing negative films, in which 11 is a synthetic resin sheet, 14 is a fall prevention part, and 16 is a perspective view showing an example of a pocket for organizing negative films. Storage pocket portion 17 indicates a heat welded portion.

Claims (1)

[Scope of utility model registration request] It consists of a combination of a topsheet and a backsheet that has a part protruding from the topsheet on one side of the topsheet, with the end of the topsheet at the protruding part of the backsheet serving as an entrance, and both sides of the entrance serving as an entrance. A storage pocket is formed by fixing the three sides of the front and back sheets to each other while leaving them open at a certain distance. A pocket for organizing paper sheets, characterized in that a protruding part is fixed to form a fall-preventing part.
