DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail based on embodiments shown in the drawings. FIG.
FIG. 2 is a front view and a side view of the cylindrical container of the present invention.
[Fig. 4] is a plan view of the tubular container showing the internal shape when opened at the hinge portion.

As shown in FIG. 1, a container (10) for a tubular body according to the present invention comprises a pair of half-cut hollow tubular bodies (1, 1 '), a hinge part (2) for connecting them in an openable and closable manner, and It is composed of cushioning members (3, 3 ') provided in the vicinity of both ends of both half-cut hollow cylinders. Thus, the pair of half-cut hollow cylinders (1, 1 ') has a size capable of accommodating the cylindrical body inside thereof, specifically, the inner diameter thereof, and the cylindrical body and the flange portion of the cylindrical body. Of these, it is necessary to be larger than the maximum outer diameter. The material of the hollow cylinder is not particularly limited as long as it does not substantially deform during handling,
Usually, it is preferable to use a commercially available paper tube cut in half, which is prepared by stacking papers, in terms of strength and economy. The hinge part (2) is not particularly limited in its form and material as long as it can connect the side edges of the pair of half-cut hollow cylinders (1, 1 '). In the illustrated case, a cloth adhesive tape is applied over almost the entire length of the side edge to form the hinge portion (2), but as long as it can be bent by opening and closing a number of times, an adhesive tape made of paper or a plastic sheet is used. But it doesn't matter.

Further, since the cushioning members (3, 3 ') are used to support both ends of the tubular body, it is not necessary to provide them over the entire length of the half-cut hollow tubular body (1, 1'), but rather the tubular body. It is usually provided only in the vicinity of both ends of the half-cut hollow cylindrical body so as not to come into contact with the photoconductor layer on the surface of the cylindrical body. In addition, the cushioning members (3, 3 ') are half-cut hollow cylinders (1,
It is fixed to the inner surface of 1 ') using suitable means, for example an adhesive. Then, on the inner surface of the cushioning member (3, 3 ′), as shown in FIG. 2, the recessed portions (31, 31 ′) necessary for sandwiching both ends of the tubular body without allowing them to move. Is provided. In particular, when the tubular body has a flange portion at one end or both ends, it is necessary to design the shape of the concave portions (31, 31 ') according to the shape of the flange portion. Of course, the recessed portion may be a shape in which the flange portion is completely fitted, but even if only part of the flange is fitted, when both half-cut hollow cylindrical bodies (1, 1 ') are closed, both ends of the cylindrical body are closed. Any recess may be used as long as it has a shape that can be clamped without moving the part. It should be noted that one end that does not have a flange portion is usually provided with a recessed portion that matches the outer diameter of the tubular body and is shorter than the length without the photoconductor layer.

Further, on the outer surface of the cushioning member (3, 3 '), the plane portion (32) shown in FIG. 1 (a) or the same figure (b) is shown.
The leg portion (33) shown in FIG. Then, in the case of the illustration,
In order to ensure stability when the container for a tubular body is placed on a flat surface in either open or closed state, the flat surface portion (3
2) and the leg part (33) are formed by a hollow cylinder (1,
1 ') have both, but it is sufficient if either one of the half-cut hollow cylinders has this, as long as it secures the stability in the closed state. When the flat portion (32) is provided, it is parallel to the half-cut surface of the hollow cylindrical body, and its height is not less than 1/2 of the outer diameter of the hollow cylindrical body.
In other words, it is necessary that the distance from the half-cut surface to the flat surface portion is equal to or larger than 1/2 of the outer diameter of the hollow cylindrical body, and the area can return to the original state without starting rotation with a slight inclination. It should be large enough to ensure stability. When the leg part (33) is provided,
You need at least four legs that have the same height,
It is preferable that two buffer members are provided at both ends. The distance between the two must be large enough to ensure stability so that it can return to its original position without starting rotation even if it is slightly inclined. The height of the leg portion (33) is the same as that of the flat portion, and the height is not smaller than 1/2 of the outer diameter of the hollow cylindrical body. In other words, the height from the half-cut surface of the hollow body to the tip of the leg portion. It is necessary that the distance to is equal to or larger than 1/2 of the outer diameter of the hollow cylindrical body.

The flat portion (32) and the leg portion (33)
1A and 1B, it is necessary to partially cut out the vicinity of both ends of the half-cut hollow cylindrical body so that the outer surface of the cushioning member is exposed from this. It is convenient for manufacturing the container (10) for a body. In addition, the flat part (3
2) or the leg portion (33) is usually provided in the buffer members at both ends of the half-cut hollow cylinder, but when the height is the same as the outer diameter of the hollow cylinder, only the buffer member at one end is a flat surface. It may have only a part. The cushioning member (3, 3 ') is generally made of styrofoam, but if it is a material that is easy to manufacture the recess and has appropriate cushioning properties and physical strength,
There is no particular limitation.

[0010]

According to the present invention, the main part of the container is
By avoiding the risk of the container being deformed during transportation and the inner drum being contacted and damaged, the hollow semi-cylindrical body located near the outer surface of the drum, which is vulnerable to damage, is made of paper tube that is strong and does not substantially deform. it can. Also, since the entire container can be made small, when the user attaches it to the machine and transports it,
Space saving can be achieved. According to the present invention, the outer surface of the cushioning member provided in the vicinity of both ends of the container has a flat portion or four legs, so that the stability of the container is good, and if this is housed in the outer box, it will be inside the outer box. Stability is also good. In the present invention, when using the paper tube double-halved hollow cylinder, the styrofoam cushioning member, and the adhesive tape hinge part, and when using an outer box made of corrugated cardboard, the price is low, so one-way use is used. Can be disposable.
