[0002]

2. Description of the Related Art At present, as a form of selling photos at a store, there is known a method of selling photos in a wagon or selling them hanging on a display stand. A typical form of a 135-size film that is sold by being hung on a display stand is a tongue end in a container such as a resin patrone or a metal patrone standardized by the ISO standard while being wound on a shaft. After being stored in a state where it comes out of the film door, it is packed in a resin container (also called a resin can) and packaged.
There are known a form in which a plurality of pieces are collectively sealed and packaged in a thermoplastic film bag on which the identification design is printed, and a form in which a plurality of pieces are put in an outer box on which the identification design is printed and packed with a shrink film.

In recent years, there is a tendency that the ratio of purchasing a plurality of such films, which is cheaper than purchasing films one by one, is increasing. Furthermore, in order to effectively use the display space in stores, various display packages have been proposed. For example, in Japanese Patent Application Laid-Open No. 8-262463, a patrone is stored in a film case (resin can),
Further, there is disclosed a package in which film cases are configured to be connectable to each other by attachment and detachment, and the film case is attached to a support board. Japanese Patent Application Laid-Open No. 9-586283 discloses a package in which a plurality of decorative boxes having hanging portions for hanging small boxes containing patrones are integrated. Japanese Patent Application Laid-Open No. 9-90569 discloses a package in which a case accommodating a patrone is accommodated in a storage box having horizontally long hanging pieces for accommodating a case horizontally in a vertical position.

[0004] These packaging forms are certainly convenient when used, but from the viewpoint of environmental friendliness in recent years, the used resin cans, outer boxes, etc. come out as waste, so they can be said to be preferable packaging forms. Further improvements have been desired.

[0005] As a package responding to these demands, Japanese Patent Application Laid-Open No. H11-258737 discloses a package of patrone housed in a blister container having a transparent plastic cover and a hanging portion made of a base material. I have. By storing in a transparent container, the design of the patrone can be seen directly, so the outer box used conventionally is not required, so it is an excellent packaging form from an environmentally friendly viewpoint, but it has the following problems. understood.

[0006] 1) Fog caused by light piping from the tongue end of the patrone coming out of the film inlet / outlet, which was not considered a problem because it was housed in an outer box.

2) Since the tongue end must be stored in a state wound around the patrone, the design is hidden.
Poor identification of stored patrone.

[0008] 3) When the patrone stored during transportation is rotated and the patrone is displayed at a store for a long time with the film entrance facing upward, there is a risk of light leakage from the film entrance.

[0009]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to eliminate the fogging caused by light piping, to make it easy to identify a patrone, to prevent light leakage from a film entrance and exit, It is an object of the present invention to provide a photographic film package having a good shape.
