Characterized in that a plurality of flaps integrated with the tubular body are passed through slit-shaped openings provided in the sides of the side plate in advance so that the flaps pass outward, and the flaps are joined to the folding side plates from the outside. Achieved by a magazine for roll photosensitive materials.

In the present invention, the material used for the body of the magazine is preferably cardboard or corrugated cardboard in consideration of disposability, but resin, aluminum, ceramics or other materials are combined with cardboard or corrugated cardboard in consideration of moisture resistance. It may be a composite material.

In the present invention, the material of the side plate is A
Thermoplastic resins such as BS resin and polyethylene, paperboard, and other materials are also used, but thermoplastic resins are preferable.

As a method of joining the flap and the side plate,
It is preferable to bond the contact surface between the flap and the side plate with an adhesive or the like, and a method of sticking and bonding the flap to the side plate with adhesive tape or the like can be mentioned, but if there is no problem in fixing the tubular body and the side plate. It is not limited to the above.

As a material for joining the flap and the side plate,
For example, thermosetting adhesive (eg, amino resin, polyester resin, polyurethane resin, etc.), thermoplastic adhesive (eg, polyvinyl acetate resin, vinyl acetate, vinyl chloride copolymer, acrylic resin, polyamide resin, etc.), hot melt Adhesives (Generally thermoplastic adhesives based on other components; eg ethylene-vinyl acetate copolymer (EVA) polyethylene, atactic polypropylene (APP) ethylene-ethyl acrylate copolymer (EEA) polyamide,
Curable adhesives such as polyester).

[0014]

The present invention will be described below in detail with reference to examples.

FIG. 1 is a perspective view showing an embodiment of the magazine of the present invention. 2 shows an exploded perspective view of the magazine of the present invention. The flap 4 integrated with the tubular body 1
Was passed through a slit-shaped opening 5 provided in advance on the side of the side plate 2 so that the flap 4 would pass outward, was folded from the outside, and was joined to the side plate 2 to fix the tubular body and the side plate. In this embodiment, the body 1 is made of cardboard and the side plate 2 is made of ABS resin.

The side plate used in the magazine of the present invention is one designed so that a step is provided at the portion where the side plate and the flap are joined so as not to hinder the setting of a plate making machine or the like, and the flap does not rise from the side plate surface. use. FIG. 3 shows a plan view of a side plate provided with steps, and FIG. 4 shows a side view of the side plate provided with steps.

As a portion for joining the flap and the side plate,
Although it may be joined with multiple flaps, one side is joined to one side of the side plate and one place is joined to the opposite side in consideration of facilitating magazine separation work after using the photosensitive material. Is preferred. Further, it is preferable to remove the side plate notch 9 on the drawer opening 8 of the magazine in order to maintain the light shielding property. In the present invention,
The slit-shaped opening 5 through which the flap passes was provided on two sides opposite to the position where the notch 9 of the side plate was removed, and the flap and the side plate were joined.

Regarding the folding direction of the flap, the flap was joined to the center of the side plate so as not to affect the light blocking effect of the magazine. At this time, in order to facilitate folding, it is preferable to put a ruled line inside the flap to be folded. On the other hand, if they are folded and joined, light easily enters the magazine from the slit-shaped opening 5 through which the flap passes, and the light-shielding property becomes insufficient, so the photosensitive material stored inside is exposed before use and cannot be used. May be.

The size of the flap is not particularly limited as long as it does not hinder the fixation of the tubular body and the side plate, but it is necessary to facilitate workability in assembling the magazine and facilitating the magazine separation work after the photosensitive material is used up. Considering this, it is preferable that the width dimension is set to 1/5 to 1/2 of the side plate width dimension, and the length dimension is designed so as not to overlap the flap on the opposite side when the flap is folded. In the present invention, the flap width dimension is 1/3 of the side plate width dimension, and the length dimension is designed to be 15 mm, and the tubular body and the side plate are fixed.

At the joint portion, three points of adhesive were applied to the wall of the step 6 in the side view of the side plate shown in FIG. 4, the flap and the side plate were joined, and the tubular body and the side plate were fixed. If the number of places where the adhesive is applied to the wall of the step 6 is increased, the tubular body and the side plate can be more firmly fixed, but it goes without saying that the separating operation becomes difficult.

When the magazine is discarded after the photosensitive material is used up, the flap joined to the side plate is peeled off, the tubular body and the side plate are removed, and the magazine is separated and discarded. Alternatively, the side portion where the flap is folded back may be cut or a perforation may be made in advance so that the side portion can be easily peeled off.

[0022]

According to the magazine of the present invention, the body and the side plate can be easily separated at the time of disposal after use of the photosensitive material, and the load of the separation work, which conventionally required a great deal of labor, has been significantly reduced. . In particular, when the body is made of paper and the side plate is made of resin, the sorting and disposal work can be performed more smoothly, and a great effect is obtained. Also, in the case of collecting the magazine after using the photosensitive material, it is possible to obtain advantages such as space saving in storage and transportation by decomposing the empty magazine. Through these effects, we were able to contribute to the overall improvement of our image as an environmentally friendly product.
