Description

[Detailed Description of the Invention] The present invention relates to a storage bag for rolled photographic film and a method for manufacturing the same. In storage bags, when the storage bags are appropriately cut and provided to general households, the cut storage bags are rolled into rolls that can be directly organized and bound into a set of binders such as loose-leaf ones at home. The present invention relates to a photographic film storage bag and a manufacturing method thereof.

At the photo lab, where a large amount of photographic film collected from photo shops is developed, the bag for storing the developed negative film is used by the captain, so the film is wound into a roll and used to process the negative film. The film is cut and used as appropriate depending on the amount of film.

However, when the cut negative film is placed in a bag, it is very troublesome to take it home and bind it into a binder, etc., as it requires drilling holes each time. In the end, I didn't organize it and left it in a mess, so I'll do it at a later date.

Even if an attempt was made to print the film again, it would be difficult to find the desired negative film.

Therefore, in view of the above-mentioned points, this invention has been developed in order to facilitate the organization of negative films by allowing storage bags for photographic film to be directly organized and bound into a loose-leaf type binder. The gist of the roll-shaped storage bag for photographic film is that it is a strip-shaped storage bag in which a plurality of long and narrow storage bags for photographic film made of film sheets are connected in parallel in one direction. A storage bag for photographic film is formed, and this storage bag is wound into a roll shape, and binding holes are formed at predetermined intervals along this edge near the continuous edge of the bottom side of the storage bag. The gist of the manufacturing method for storage bags is as follows:
A plurality of elongated storage bags for photographic film made of film sheets are connected in parallel in one direction to form a belt-shaped storage bag for photographic film, and the storage bag is rolled up into a roll. At the same time, the stitching holes are sequentially punched at regular intervals along this edge near the continuous edge of the bottom side of the bag. .

Hereinafter, the present invention will be described in detail with reference to the drawings.

That is, the reference numeral 1 shown in the figure is a storage bag for photographic film, and in order to accommodate a plurality of photographic films, one bag is formed into a band shape with openings 11111 connected in parallel in one direction. By shifting one long strip-shaped film sheet so that the open edge of the film sheet 3 located on the top surface is slightly inward from the open edge of the film sheet 4 located on the bottom surface, a step-like σ old film sheet is formed. It is folded in two parallel to the technique direction so as to provide a corner 5, and a sealing portion is attached parallel to the folded edge 6 near the folded edge 6, which is the bottom end on the opposite side of the first opening 50. 7 is welded in a linear or dotted line shape, and further a linear or dotted seal portion 8 is formed in a direction perpendicular to the stopper seal portion 7 from the vicinity of the stopper seal portion 7 toward the vicinity of the opening 5, and is attached to the photographic film. The space 2 for storage 18J and the adjoining auxiliary gap 9, which is not bathed, are arranged alternately.

The photographic film storage bag 1 is wound into a roll, and between the bent edge 6 and the stopper seal part 7 there are 2 parts defined by the standards for binders of a type such as loose-leaf. Binding holes 10 are provided continuously in parallel with the bent edge 6 at different hole diameters and intervals.

Moreover, as shown in FIG. 2, this photographic film storage bag 1 is manufactured by automatically performing the steps of folding in half and forming the stopper seal portion 7 and the seal portion 8 by a storage bag manufacturing machine 11, as shown in FIG. What comes out of the storage bag making machine 11,
The binding hole 10 is punched in the continuous surface by the perforator 12 as described above, and then the sheet is sequentially wound into a roll by the winder 11A13.

The binding hole 10 can be made stronger by attaching a herring-shaped reinforcing sole (not shown) to the binding hole 10.

Since this invention is constructed as described above, if the developed negative film is stored in a developing laboratory, cut into appropriate pieces, and used, the binding holes 10 are already punched, so that it can be carried at home. It's very convenient because you can bind the items directly into the binder when you get home and organize them.

This makes it easy to organize negative films.

That is, a plurality of elongated storage bags for photographic film made of film sheets are connected in parallel with their open sides in one direction to form a belt-shaped storage bag for photographic film. By winding up the cover 1 into a roll,
If you cut the photographic film according to the length and use it,
It is very convenient in photo labs where photographic film is developed into various types of thick weave, and in addition to winding it up as described above, it is also possible to wrap it around the continuous edge of the bottom side of the storage bag. Coupled with the fact that the binding holes 10 are provided at predetermined intervals, it is possible to bind the photographic film directly into a binder such as a loose-leaf binder, and at that time, the photographic film can be stored and taken out from the direction opposite to the binding side. This makes it easier to organize photographic film.

Then, the photographic film storage bag 1 is rolled up into a roll, and at the same time, the binding holes 10 are sequentially opened, so that when the photographic film storage bag 1 is wound into a roll, the binding holes 10 are not punched. Because of this, there is no need to open the binding holes 10 after cutting the storage bag 1 into 1 pieces, which is very convenient in places where large quantities are used, such as in photo labs. 1 is a series of steps in which the binding holes 10 are opened at the same time as winding, and the time for opening the binding holes 10 is included in the winding time, so it is a simple process.

As explained above, according to the present invention, it can be used very economically in photo labs that develop large quantities of photographic film, and it can also be cut as appropriate and provided to ordinary households. 2+ (+ method σ) You can organize and bind directly and easily.

You can organize your photographic film very easily]
This has a 1 degree effect.
