[0002]
[Prior art]
Conventionally, a corrugated cardboard box having a structure as shown in FIGS. 5 to 7B has been used as a corrugated cardboard box for storing and transporting this type of roll body.
[0003]
Specifically, as shown in FIG. 5, the conventional cardboard box has a longitudinal folding curve, and the side plate 51, the end plate 52, the side plate 53, and the end plate 54 are successively arranged in the left-right direction, and these side plates 51, 53 are provided. Further, lid plates 55 and 56 and bottom plates 57 and 58 are connected to the upper and lower edges of the end plates 52 and 54, respectively, and a joining piece 59 is connected to the left end of the side plate 51 to provide a blank plate 60 of a cardboard box. It was composed.
[0004]
In assembling and constructing a cardboard box using the blank plate 60, as shown in FIGS. 6 and 7B, the joining piece 59 connected to the side plate 51 is attached to the end plate 56, and the side plate 51, A corrugated cardboard box was constructed by forming a quadrangular frame made up of a frame 53 and end plates 52 and 54, and bending the bottom plates 57 and 58 to the lower surface of the frame and fixing them with adhesive tape (not shown). .
[0005]
When the roll body 63 in which the photosensitive film 62 or the like is wound around the core 61 as shown in FIG. 7A is stored and packed in the cardboard box configured as described above, FIG. As shown, core holders 64 are attached to and supported at both ends of the core 61 of the roll body 63, and the core holder 64 and the roll body 63 are integrally stored in the box. Are folded at the opening of the box, and an adhesive tape (not shown) is adhered to these joints, or fixed by an adhesive, staple, or the like.
[0006]
[Problems to be solved by the invention]
However, in the above-described conventional cardboard box, the frame body is erected and maintained even when the cover plates 55 and 56 are opened, so that the core holders 64 provided at both ends of the roll body 63 are maintained. Is in close contact with the inner peripheral surface of the cardboard box, and when removing the roll body 63 from the cardboard box, a finger is inserted between the core holder 64 and the standing inner periphery of the cardboard box, and the core holder 64 is held by hand. There was a problem that it was difficult to hold.
[0007]
In order to solve this problem, it is possible to use a cardboard box having an inner diameter larger than the axial length of the roll body 63 and insert a finger between the core holder 64 and the inner periphery of the cardboard box. There is also known a technique in which a gap is formed and the gap 65 is filled with a spacer 65 so that the roll body 63 can absorb vibrations and shocks generated during transportation or storage.
[0008]
However, in the technique using the latter spacer 65, a cardboard box having a dimension larger than the axial length of the roll body 63 must be used, and the spacer 65 is required in addition to the cardboard box. Therefore, there was a problem that was extremely uneconomical. Furthermore, before taking out the roll body 63 from the cardboard box, the spacer 65 has to be removed from the inside of the box, which causes problems such as complicated work and poor efficiency.
[0009]
The corrugated cardboard box for transporting a roll body according to the present invention is a completely new technology developed in view of the above-described many problems of the prior art, and in particular, a side plate, a twill plate, and a lid plate via folding lines around the bottom plate. The box is assembled and packed with only one adhesive tape without using conventional joining pieces and adhesives, etc. by sequentially connecting the bent horizontal pieces and the bent overlapping pieces, etc., and assembling them. In addition, the present invention provides a completely new technique in which a roll body stored in the box can be taken out simply by flattening the box by removing the adhesive tape.
[0010]
[Means for Solving the Problems]
A cardboard box for transporting a roll body according to the present invention is an invention that has fundamentally improved the above-mentioned conventional problems, and the gist of the first invention is that of a roll body in which a film or the like is wound around a core. In a cardboard box for supporting and transporting a winding core from both ends, a side plate and a cover plate are sequentially connected to both side edges of the bottom plate through a folding line, and both ends of the bottom plate The end plate is formed by connecting a bending plate and a horizontal bending piece in order to each other through a bending curve, and further, a bent overlapping piece is connected to each end edge of the tapping plate through a bending curve. It is a corrugated cardboard box for transporting a roll body, characterized in that the roll body stored in the box can be easily taken out by developing it into a shape.
[0011]
In the first aspect of the invention, the side plate, the end plate, the cover plate, the bent horizontal piece, the bent overlapping piece, etc. are sequentially arranged around the bottom plate through the folding line. Thus, a box that can be easily disassembled can be formed by raising the side plate and the end plate and abutting the bent overlapping pieces respectively connected to both end edges of the end plate to the inner surface of the side plate.
[0012]
The roll body accommodated in the box can be assembled with the above-described box in a state where the core holder is mounted on the bottom plate in advance with the core holders attached to both ends thereof. The box constructed in this manner tilts the left and right folded horizontal pieces to the upper opening, and then tilts the lid plate on these folded horizontal pieces to seal the box, and adhesive tape is attached to the joints of the left and right lids. The box can be packed by sticking.
[0013]
Therefore, when taking out the roll body from the inside of the box, by removing the adhesive tape attached to the joint part of the left and right lids, the entire box is developed in a flat shape, and the roll body on the bottom plate can be easily You can take it out.
[0014]
The gist of the second invention of the corrugated cardboard box according to the present invention is that the height dimension of the bent overlapping piece is adjusted to the height dimension in the corrugated box and the dimension of the bent overlapping piece with respect to the axial width dimension of the bottom plate is set. It is a corrugated cardboard box for transporting a roll body according to the first invention, characterized in that it is equal to or more than one-fifth and the corner portions of the bent horizontal piece and the bent overlap piece are formed in an arc shape.
[0015]
In the second invention described above, since the height dimension of the bent overlapping piece is the height dimension in the cardboard box, the upper and lower edges of the left and right bent overlapping pieces in contact with the inner surface of the side plate are the bottom plate. In addition, it is in close contact with the cover plate, thereby supporting the end plate and preventing the end plate from falling down and preventing backlash in the box of the stored roll body.
[0016]
Since the width dimension of the bent overlapping piece with respect to the shaft width of the bottom plate is equal to or more than 1/5, the upper and lower edges of the bent overlapping piece can be brought into contact with the bottom plate and the cover plate relatively long, respectively. It is possible to support the wife board stably by this.
[0017]
By making the corner portions of the bent horizontal piece and the bent overlap piece into an arc shape, the box can be smoothly assembled and disassembled, and safety during operation can be ensured.
