[Example] Figures 1 to 3 show a first embodiment of the film packaging body according to the present invention. Figure 1 is an overall side view, Figure 2 is a side view during production, and Figure 3 is a partial view. FIG. In each figure, 1 is a spool molded from a light-shielding resin material that is difficult to transmit moisture, and 2a and 2b are flanges formed at the ends of the spool 1.

Reference numeral 3 denotes a film, and this film 3 is wound around the spool 1. 4 is formed in a tapered shape on the connection side, has a width wider than the width of the film 3, that is, a width slightly wider than the width between the flange 2a and the flange 2b, and is made of a light-shielding material that does not easily allow moisture to pass through. He is a leader. The length m of this leader 4 must be such that when the leader 4 is wound around the outer periphery of the film 3 wound on the spool 1, it will be wound at least once around the flanges 2a and 2b. Yes, preferably flange 2
The length is such that it can be wound around a and 2b at least one and a half times, more preferably at least three times.

Reference numerals 5a and 5b are hooks (holes) formed at the tip of the leader 4. Note that the hooking portions 5a and 5b may be formed directly on the leader 4, or may be formed by, for example, a metal plate with a thickness of less than 5 mm or the same material as the leader 4, and connected to the leader 4. It's okay. As shown in FIGS. 1 and 2, after the film 3 is wound around the spool 1, a leader 4 is connected to the end of the film 3.
The film package F according to the present invention is obtained by winding the leader 4 and then heat-sealing and bonding both end portions of the leader 4 to the end faces of the flanges 2a, 2b at the ends of the spool 1. In FIG. 1, the parts indicated by A and B are heat-sealed parts.

Furthermore, as shown in FIG. 2, the flanges 2a,
The end surfaces of the flanges 2b are flat in consideration of heat sealing properties, and as shown in FIG. 4, the end surfaces of the flanges 2a and 2b are preferably wide in consideration of heat sealing strength. Further, as shown in FIG. 5, the flanges 2a and 2b may have a rectangular shape such as a square to facilitate heat sealing, and are not limited to a circular shape.

[0014] When the film package F is constructed as described above, the film 3 has a complete light-shielding property even if it is not housed in a paper box as in the past, and
The moisture proofing measures are also perfect. In addition, since there is no need to use conventional plastic cans or paper boxes to ensure light-shielding properties and moisture-proofing, it is also effective in preventing dust.

Furthermore, the trouble of storing the product in a plastic can or paper box can be saved. FIG. 6 is a side view showing a second embodiment of the film packaging body according to the present invention. The film package F of this embodiment has the structure of the first embodiment, but the bonded parts of the wound leaders 4 are bonded to each other with a weakly adhesive adhesive 6, and the bonded separation surfaces of the leaders are bonded together. The structure is designed to prevent light and moisture from entering the interior through the gaps.

[0016] Therefore, the material of this example is even more excellent in moisture-proofing and light-shielding properties than those of the previous example. Furthermore, 7
is a pin integrated with the adhesive 6, and is configured such that by pulling out this pin 7, the adhesive 6 is peeled off from the leader 4, and the adhesive state between the wound leaders 4 is released.

FIG. 7 is a perspective view showing a third embodiment of the film packaging body according to the present invention. In the film package of this embodiment, the film package F of the first and second embodiments is further housed in a plastic container 8 having a predetermined shape. This container 8 is constructed by integrating two halves, for example, and is configured to be opened as shown in FIG. 8 by removing a pin 9. In this open state, the container 8 is provided with arc-shaped flanges 10a and 10b that are hooked onto the flange 2a or 2b so that the film package F stored therein does not lose its posture. That is, when the container 8 is closed, the flange 10a and the flange 10b hold the flange 2a or 2b of the film package F with their one ends close together, as shown in FIG. In this state, as shown in FIG. 10, the flange 10a and the flange 10b hold the flange 2a or 2b of the film package F with their other ends close together, and in any case, the flange 10a, 10b of the container 8 The structure is such that the posture of the film package F is maintained.

As shown in FIG. 7, even if the hooks 5a and 5b at the tip of the leader 4 of the film package F are housed inside the container 8, or as shown in FIG.
The hooking parts 5a and 5b at the tip of the container 8 may be exposed outside the container 8. However, as shown in FIG. 7, when the container 8 is stored inside, the positions of the hooks 5a and 5b at the tip of the leader 4 are in a predetermined position when the container 8 is opened. It is preferable from the viewpoint of the film drawing operation to keep it at

In the case where the container 8 is provided outside the film package F as described above, this container 8
There are no major restrictions on the constituent material or shape of the container 8, and therefore, it can be made into a unique shape, that is, a character design can be adopted as the shape of the container 8, and added value can be increased. In addition, FIG. 12 shows a part of the mechanism on the camera side, where 11 is a film winding shaft, 12a and 12b are hooked to hooks 5a and 5b at the tip of the leader 4, and are used to pull out the film. It is the nail of. That is, when the film package F is loaded into the camera, the claws 12a and 12b are hooked to the hooks 5a and 5b at the tip of the leader 4, and the film winding shaft 11
The rotation causes the film to travel one frame at a time. Note that 13 is a slit formed in the film winding shaft 11, into which the tip of the leader 4 is housed.
