Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll-shaped product holding member.

[0002]

2. Description of the Related Art There are various types of roll-shaped (hollow-shaped products having both ends opened) products such as a thermal transfer ribbon, a photosensitive drum, and a roll-shaped photosensitive material. Will be sent out. At this time, the protruding portions (locking portions) of the holding member as shown in FIG. 5 are fitted into the hollow portions at both ends of the roll-shaped product, and are housed in a box in that state. The holding member in FIG. 5A is an example of an injection molded product, and the holding member in FIG. 5B is an example of a foamed plastic molded product. The holding member shown in FIG. 5C is an example in which sheets are laminated and a paper tube having a size large enough to be inserted into a hollow portion of a roll-shaped product is bonded to the center of the sheets.

[0003]

However, resin molded articles such as injection molded articles and foamed plastic molded articles require a large cost for a mold, so that the product cost of the holding member is increased. The resin holding member is cumbersome for the subsequent treatment. The paper holding member of FIG.
Since the laminated sheet material and the paper tube are different members made individually and manufactured by combining them, the production cost tends to increase. SUMMARY OF THE INVENTION It is an object of the present invention to provide a roll-shaped product holding member which can be easily assembled from a single sheet material, and the sheet material can be formed by using a punching die, thereby reducing investment costs. It is.

[0004]

According to the present invention, first, folds (61), (62) and (63) are formed on a substantially square bottom wall (1) having a cross or X-shaped cut in the center. ) (64)
The upper walls (21), (22), (23), and (24) are connected to each other via one side, and one of the opposing upper walls (21) and (23) is parallel to one of the cuts in the bottom wall (1). The locking piece (3) provided with cuts (81) and (83) extending from the edge on the extension line
1) and (33) are connected to each other through folds (71) and (73), and the other opposing upper walls (22) and (24) are parallel to the other cut of the bottom wall (1). Alternatively, the notches (82) (8) extending to the upper walls (22) (24) which are
The locking pieces (32) and (34) provided with 4) are folded (72).
(74) is made of a sheet material connected continuously, and the upper walls (22) and (24) are folded back so as to be in contact with the bottom wall (1);
Further, the locking pieces (32) and (34) are bent at 90 ° and inserted into the cuts of the bottom wall (1) so as to protrude, and similarly, the upper walls (21) and (23) and the locking pieces (31) and (33). Are provided, and the locking pieces (31) and (33) are inserted into and cut out from the cuts of the bottom wall (1) to assemble the roll-shaped product holding member.

[0005] Secondly, there is provided the above-mentioned first roll-shaped product holding member, characterized in that the shape of the location for holding the product end is X-shaped. Thirdly, there is provided the first roll-shaped product holding member, wherein a shape of a portion for holding a product end is a cross. Fourth, the first
There is provided a roll-shaped product holding member characterized in that two sheet materials before the second assembling are continuously connected and assembled.

[0006] The holding member for the roll-shaped product of the present invention is obtained from a single sheet material, and this sheet material may be formed by laminating a plurality of sheets of paper, paper having a large rejection amount, corrugated paper, paperboard, or the like. Used. Preferred sheet materials have a thickness of 0.5 to
It is in the range of 5 mm. Although no adhesive is used for assembling the holding member, it may be used as needed.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail with reference to the drawings. FIG. 1A is a developed view showing a state where the sheet material of the holding member of the present invention has been punched out.
(B) is a perspective view of the assembled state, in which the place for holding the product becomes an X-shape. FIG. 2 (a) is a development view of another example, and FIG. 2 (b) is a perspective view of a state where the product is assembled, where a place for holding a product has a cross shape. Here, the sheet material of FIG.
A major difference from the sheet material of FIG. 7A is that the cut provided in the center of the bottom wall 1 is an X-shaped cut but a cross-shaped cut. Since there is no difference, the description will be made with reference to the sheet material shown in FIG.

[0008] The bottom wall 1 is square, but the square may be slightly cut. Upper wall 21, 22, 23, 2
4 and the length of the locking pieces 31, 32, 33, 34 are half of the length (L) of one side of the bottom wall 1 or slightly shorter. Further, a cross cut is provided at the center of the bottom wall 1, but cuts 81 and 83 are provided in the locking pieces 31 and 33 on the extension of the cut 11 in the vertical direction in the drawing, and Cuts 82 and 84 are provided on the upper wall 22 and the locking pieces 32, and on the upper wall 24 and the locking pieces 34 over the folds 72 and 74 on the extension of the cut 12 in the horizontal direction in the drawing. Here, the cuts 8 provided in the locking pieces 31 and 33 are provided.
Nos. 1 and 83 extend from the edge to a position almost in the middle, and have a length of approximately L / 4. On the other hand, the cut 8
2 and 84 straddle the folds 72 and 74, and the folds 72 and 7
4, the upper wall 22 and the locking pieces 32, and the upper wall 24 and the locking pieces 34
Both are approximately the length of L / 4.

In order to assemble the sheet material shown in FIG. 2A as shown in FIG. 2B, first, the upper walls 22, 24 are to be assembled.
Are bent inward on the paper surface, and the locking pieces 32 and 34 are further
Into the notch 11 so as to project toward the back side of the paper. Next, the upper walls 21 and 23 are bent inwardly, and the locking pieces 31 and 33 are inserted into the notches 12 of the bottom wall (1) through the notches 82 and 84 of the already bent upper walls 22 and 24, and the back side of the paper is inserted. It should just be made to protrude. Cuts 81, 83 of locking pieces 31, 33 are cuts 82, 84 of locking pieces 32, 34.
Thus, a cross-shaped engaging piece is formed.

FIG. 3 (a) shows a suitable sheet material in which two members having the structure shown in FIG. 1 (a) are arranged.
A holding member as shown in (b) is obtained. According to this, two roll-shaped products can be arranged and packaged. FIG. 4 shows an example in which a roll-shaped product 5 is packaged using the holding member 4 of the present invention. 6 is a box in the figure.

The roll-shaped product holding member of the present invention can be easily manufactured simply by assembling a die-cut sheet material. Since the holding member is in a sheet shape before assembly, storage and transportation are easy. Further, since the holding member is formed of a sheet material such as paper, there is no problem in disposal such as disposal.

[0012]

【The invention's effect】

(1) According to the first aspect of the present invention, since the holding member is a single sheet material such as a paper material, the material cost is low, and the assembling is easy, so that the member cost can be reduced. (2) According to the second aspect of the present invention, the shape of holding the roll-shaped product is X-shaped, so that the load of a relatively heavy product can be held evenly above the X-shape. (3) According to the third aspect of the present invention, the holding member material is changed to 3
-10%. (4) According to the invention of claim 4, since the two holding members of claim 2 or 3 are connected, two roll-shaped products can be packaged side by side.
