Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film packaging container and a photographic film packaging body for accommodating a plurality of cartridges or cartridges in which a scroll in which a photographic film is wound around a spool is rotatably housed in a light-tight state.

[0002]

2. Description of the Related Art A typical form of a 135-size film currently sold at a store in consideration of environmental compatibility is as follows.
After being wound around a shaft, it is stored in a container such as a resin patrone or a metal patrone standardized by the ISO standard, and light-shielded, and then placed in a moisture-proof resin container (also referred to as a resin can), and then subjected to moisture-proof packaging. There are known a form in which a plurality of pieces are combined with a thermoplastic film on which an identification design print is applied, and a form in which a plurality of pieces are put in an outer box on which the identification design is printed and packaged with a shrink film. Advanced Photo Film (APS)
In the case of film, the ISO
After being housed in a resin cartridge standardized by a standard, a form similar to that of a 135-size film is known. In recent years, there is a tendency that the rate of purchasing a plurality of such films, which is cheaper than purchasing films one by one, is increasing.

[0003] These packaging forms are certainly convenient when used, but further improvement has been desired since the used resin cans come out as waste from the viewpoint of environmental friendliness in recent years. As a packaging container that meets these demands, for example, Japanese Patent Application Laid-Open No. 5-49619 discloses a form in which a 135-size film light-shielded and packaged is placed in parallel in a resin tray container, and the upper portion of the tray container is sealed. . Certainly, this form is effective in reducing the number of resin cans, but as a problem in use, it cannot be completely sealed after opening, so it should be stored for a long time in a place with high humidity. There was a danger that the photographic film was wasted because it could not be kept and had to be used in a short time.
Also, if used as a container for storing photographic film after shooting, if it is put in a shooting bag, it may be mixed with unphotographed film spilled from the tray container and there is a risk of misuse. It was inconvenient because it had to be put in a container that had been damaged. Japanese Patent Application Laid-Open No. 6-67355 discloses a container improved in light of these drawbacks.
By storing 35 size film in series in a cylindrical resin container with a sealing lid at the front and rear opening, after filming is completed, it is stored again from another opening to avoid mixing with unphotographed film. Although it can be resealed after opening, it can be used without taking care of the storage place, but the improvement is recognized, but the only problem is that the cylindrical shape and the length of the body make it weak in strength and travel If you carry it in your bag and carry it around, it may be pushed by a hard object, denting the cylindrical resin container and deforming the stored patrone, making it unusable. Care must be taken not to store it on the side of objects that have, and it is difficult for users to use it, and improvements have been desired.

In Japanese Utility Model Application Laid-Open No. 5-90488, individual film containers are connected in order to improve the drawbacks of being scattered and inconvenient to handle when carrying a plurality of items, and of being bulky in space.
A technique for reducing the number of outer boxes by forming a collective package has been disclosed. Although it is effective to reduce bulk and packaging material by using a collective package, it is necessary to remove the connecting part when taking out the film, open the lid, and take out the film when using it. Therefore, it has been desired to develop a package that is more complicated and easier to use in terms of use.

[0005] In over-the-counter sales,
A package that is convenient for use is desired, and in particular, a package in which a plurality of containers as described above is packaged with a thermoplastic resin film for travel and outdoor use is sold at a store, but all have the same form. It has been turned into a rut and has become inconspicuous, and the development of a conspicuous package has been desired by the sales side.

[0006]
