Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a roll-shaped photosensitive material package.

[Background of the invention]

Generally, a roll of photosensitive material is housed in a light-shielding package so that it can be loaded into a machine such as a developing and printing machine in a bright room. Conventionally, there have been two types of packaging: refillable types made of metal or synthetic resin, and disposable types made of paper.

However, although the above-mentioned package is composed of an interior body that supports the roll-shaped photosensitive material and an exterior body for the purpose of blocking light, the light-shielding property at the exit of the photosensitive material formed in the interior body and the exterior body is If the holder holding the rolled photosensitive material tube is made of paper and has a larger diameter than the one currently in use (for example, 400 feet or more), the photosensitive material drawer must be removed. The disadvantage was that the load was large. On the other hand, even if the above-mentioned disadvantages could be solved with the packaging, it was troublesome to collect it for refilling, and in the case of resin molded products, it was very expensive due to mold costs etc. Not only that, but the disposal process was troublesome.

[Purpose of the invention]

The present invention is aimed at solving the above-mentioned drawbacks, and provides a disposable roll-shaped photosensitive material package that has light blocking performance that can withstand loading in a bright room and can reduce the load of pulling out a photosensitive material with a large diameter. The purpose is to

[Structure of the invention]

In order to achieve the above object, the present invention includes a back plate and side plates connected to both edges of the back plate, each side plate having both ends of a tube of photosensitive material wound in a roll shape. The interior body has a supporting member and has a light-shielding means on the back plate and an outlet for the photosensitive material, and a portion of the interior body corresponding to the back plate has an opening/closing plate that can be opened and closed; It is constructed so that it is covered with an exterior body in which a cutout window is formed in the opening/closing plate to expose the outlet.

〔Example〕

Next, the present invention will be described based on embodiments shown in the accompanying drawings.

In the figure, 1 is a package body, and the package body 1 includes an inner body 2 and an outer body 3 that encloses the inner body 2.
It consists of The interior body 2 has a back plate 2 as shown in the fourth diagram.
1, and side plates 22 and 2 connected to both edges of the back plate 21.
3. The connecting portions of the side plates 22 and 23 can be bent at approximately right angles, and the center portions of the side plates 22 and 23 have a roll shape when the side plates 22 and 23 are bent oppositely as shown in FIG. It has support members 24 and 25 that can support both ends of the winding tube 41 of the photosensitive material 4 wound therein. In the embodiment, the supporting members 24 and 25 are made of laminated cardboard and punched out into a disk shape, and are rotatably supported, but there is no need to limit the material, and the pull-out load of the photosensitive material 4 is may be fixed as long as it does not become unnecessarily large.

Reference numeral 26 denotes an outlet (slit) for the photosensitive material 4 provided near the upper edge of the back plate 21, and the outlet 26 is provided with a light shielding means 27. In the embodiment, as the light shielding means 27, passage forming members 28, 28' for passing the photosensitive material 4 are installed on the inner surface of the outlet 26, facing each other, and light shielding cloths 29, 29 are provided on the opposing surfaces of the passage forming members 28, 28'. ' is attached to prevent outside light from entering. Note that the passage forming members 28, 28'
Although it is preferable to have a diagonal configuration as shown in the figure from the viewpoint of light shielding, it is not necessarily oblique. Further, the passage forming members 28, 28' are integrally molded and provided with fixing flaps 28a, 28b in order to reinforce them so that they do not deform due to the working method, but they may be freely replaced with other suitable reinforcing means. be.

The exterior body 3 is made of relatively thin paperboard, and has an opening 31 in a portion corresponding to the back plate 21 of the interior body 2.
The main part 32 has a dark box shape, and the opening/closing plate 33 is connected to the lower side of the opening 31 of the main part 32, and the opening/closing plate 33 can be inserted into the opening 31 of a flap 33' provided around the main part 32. The opening 26 for the photosensitive material 4 can be closed by
A cutout window 34 is formed to expose the.

Note that the ends of the light shielding cloths 29, 29' attached to the opposing surfaces of the passage forming members 28, 28' are shown in FIG. 2A.
Although it is made to protrude from the cutout window 34 in this case, it may be prevented from protruding from the cutout window 34 by folding it back and fixing it to the outer surface of the back plate 21 of the interior body 2, as shown in FIG.

Next, the operation of the above embodiment will be explained.

When the photosensitive material 4 wound in a roll on a tube is housed in the package main body 1, first, the side plates 22 and 23 connected to the back plate 21 of the inner body 2 are bent to face each other in a dark room. At the same time, both ends of the winding tube 41 of the photosensitive material 4 are supported by support members 24 and 25 provided at the center of each. After that, the leader tape 4' extended at the tip of the photosensitive material 4 is attached to the passage forming member 28,
A portion of the light shielding cloth 28' is made to protrude from the outlet 26 by passing between the light shielding cloths 29 and 29' attached to the opposing surfaces of the light shielding cloth 28'. Then,
After storing the opening/closing plate 33 in the open exterior body 3, closing the opening/closing plate 33, and pulling out the outer end of the leader tape 4' from the cutout window 32, the opening/closing plate 33 and the main part 32 of the exterior body 3 are connected. Seal the gap with light-shielding tape 35 or the like. As a result, the photosensitive material 4 is housed in the package body 1 in a desirable light-shielded state with the leader tape 4' partially protruding from the outlet 26 as shown in FIGS. 4 and 2. Therefore, the photosensitive material 4 can be transported as is in a bright place, and the leader tape 4'
When the photosensitive material 4 is pulled, the both ends of the winding tube 41 are rotatably supported by the side plates 22 and 23 of the inner body 2 and supported by the supporting members 24 and 25, as shown in the third figure, so the photosensitive material 4 is smoothly moved. , it becomes possible to pay out with less resistance.

〔Effect of the invention〕

As described above, the roll-shaped photosensitive material package according to the present invention includes a back plate and side plates connected to both edges of the back plate, each side plate having a tube containing the photosensitive material wound in a roll. The inner body has members supporting both ends of the inner body, and the back plate has an outlet for the photosensitive material provided with a light shielding means, and the inner body has an opening/closing plate that can open and close a portion corresponding to the back plate. Since the opening/closing plate is covered with an exterior body in which a cutout window is formed to expose the outlet, it has a light-shielding performance that can withstand loading in a bright room, and has a simple structure and can be manufactured at low cost. Furthermore, it is robust and has the excellent effect of being able to be constructed so as to reduce the pull-out load of a photosensitive material having a large winding diameter.
