TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box for accommodating a roll, which is one of the final product forms of a recording material such as a photosensitive material, an ink jet recording material, a thermal paper, and a pressure sensitive paper, and a package of the roll. In particular, a package that improves the workability of storing the roll-shaped material, that can easily remove the stored roll-shaped material in a suspended state, and that can be stored in a suspended state even after the roll-shaped material is removed. About.
[0002]
[Prior art]
In general, a roll-shaped recording material wound around a core (hereinafter, referred to as a roll) is stored or transported in a state of being housed in a packaging box, and delivered to an end user. There are various types of packaging boxes. In recent years, a packaging box in which a storage portion for storing rolls and a lid portion are formed of one piece of cardboard has been adopted. For example, it is disclosed in JP-A-6-21041, JP-A-11-338106, JP-A-2000-185726, JP-A-2001-301744, and the like.
[0003]
Roll materials of recording materials come in a variety of sizes with different widths and winding lengths.Especially for rolls that are wide and have a relatively long winding length, when the roll moves in the packaging box, the weight of the recording surface increases. There is a problem that scratches and the like occur on the surface. Therefore, it is necessary to store the roll so that the roll does not move in the packaging box. As one of the means, there is known a method of storing a roll in a suspended state in a packaging box. For example, a hanging member has been proposed in which a hanging shaft is inserted into a hollow portion of a roll core and the shaft is held by a side plate. For example, suspended members are disclosed in JP-A-10-181789 and JP-A-2001-139085.
[0004]
When a relatively heavy roll is stored in the conventional packaging box as described above, there is a problem that the end user cannot easily take out the roll from the packaging box. In particular, when the roll is suspended in the air and stored in the packaging box using the suspension member, it is increasingly difficult to remove the roll. Further, in the manufacturing process of the roll-shaped package, there is a problem that workability when storing the roll in the packaging box is poor.
[0005]
[Problems to be solved by the invention]
Therefore, an object of the present invention is to provide a packaging box in which the roll can be easily taken out of the packaging box and the roll can be easily stored in the packaging box. In particular, the roll can be easily stored in a suspended state, and the storage portion of the packaging box can be easily dismantled while the roll is stored in the suspended state, and the roll can be taken out in the suspended state. It is to provide a package.
[0006]
[Means for Solving the Problems]
The above object of the present invention has been basically achieved by the following inventions.
(1) A packaging box for a roll-shaped recording material in which a storage section and a lid section are integrally formed of one corrugated cardboard sheet, wherein the storage section can be disassembled in a state where the roll-shaped recording material is stored. Rolled recording material packaging box.
(2) A package of roll-shaped recording material, wherein the roll-shaped recording material is stored in a suspended state by a member for hanging in the packaging box.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
First, a conventional packaging box will be specifically described with reference to the drawings. FIG. 2 is a development view of a conventional packaging box, which is formed by punching out one corrugated cardboard sheet. In this packaging box, a storage portion for storing rolls and a lid portion are integrally formed of one corrugated cardboard sheet.
[0008]
In FIG. 2, the H surface and the I surface are doubled to form the front surface of the lid. That is, the H surface is folded toward the near side (inside) and overlapped with the I surface to form a front portion of the two-layered lid portion. The J surface is the upper surface of the lid. The K surface is the rear surface of the storage unit, the L surface is the same bottom surface, the M surface and the N surface are the same front surface, and the N surface is folded forward (inside) like the front surface of the lid. By overlapping with the M surface, a front portion of the two-storage storage unit is formed.
[0009]
The J1 surface and the J11 surface constitute the left side surface of the lid, and the J11 surface is folded forward (inside) and overlapped with the J1 surface to form a two-layered lid left side surface. Similarly, the J2 surface and the J21 surface constitute the lid right side surface. Then, the J12 surface and the J22 surface are inserted between the H surface and the I surface constituting the front surface of the lid, and fix the front and side surfaces of the lid.
[0010]
The L1 surface and the L11 surface constitute the left side surface of the storage unit. The L11 surface is folded inward (inside), and the L1 surface is overlapped with the L1 surface to form a double-layered storage unit left side surface. The surface and the right side constitute the storage unit. The L12 surface and the L22 surface are inserted between the M surface and the N surface constituting the front surface of the storage unit, and fix the side surface and the front surface of the storage unit. The K1 surface is inserted into the storage unit left side surface (between the L1 surface and the L11 surface), and the K2 surface is inserted into the storage unit right side surface (between the L2 surface and the L21 surface). Is fixed.
[0011]
By trapping the trapezoidal pieces 16a to 16f outward, the H-side, N-side, J11-side, J21-side, L11-side, and L21-side are folded inside the container to assemble the packaging box. (H side to L21 side) has a function of preventing and trying to return to the original position.
[0012]
In this way, the packaging box formed by assembling the developed view shown in FIG. 2, that is, the L12 surface and the L22 surface are inserted between the M surface and the N surface forming the front surface of the storage unit, and the left and right side surfaces are inserted. Since the L11 surface and the L21 surface forming the left and right side portions are fixed inward, the roll (not shown) is placed on the bottom portion (L surface). The storage cannot be dismantled. Further, in the state of the developed view (only the lid may be assembled in advance), the storage unit cannot be assembled with the roll placed on the bottom surface (L surface).
[0013]
Therefore, when the rolls are stored in a fixed state (suspended state) so as not to move in the packaging box, it is not easy to remove the heavy rolls from the storage section. Therefore, the present invention proposes a packaging box and a packaging body that can be disassembled in a state in which the rolls are housed, and can withstand the falling or falling of the packaging body during handling or transportation.
[0014]
Hereinafter, the packaging box of the present invention will be described in detail. The packaging box of the present invention is characterized in that it can be disassembled (deployed) with the rolls stored therein as described above. The packaging box of the present invention is formed by assembling a corrugated cardboard sheet obtained by cutting a single corrugated cardboard sheet with a die-cutting machine or the like. FIG. 1 is a development view showing an embodiment of the packaging box of the present invention.
[0015]
In FIG. 1, a storage unit for storing rolls includes a rear surface C, a bottom surface D, a front surface E, and flaps (D1, D2, E1, E2) forming left and right side surfaces. The lid includes an upper surface B, a front surface A, and left and right side surfaces (B1, B11, B2, and B21). The upper surface B is connected to a rear surface C of the storage unit. Although not shown, H and N planes corresponding to FIG. 2 can be connected to the front parts A and E of the lid part and the storage part, respectively.
[0016]
The packaging box is assembled by folding inward along a folding ruled line shown by a dotted line. At this time, the single dotted line is bent at approximately 90 degrees, and the double dotted line is bent at approximately 180 degrees. The feature of the present invention resides in flaps connected to both left and right ends of a bottom surface portion D and a front surface portion E forming a storage portion. That is, the flaps E1 and E2 serving as the inner surfaces of the side portions are connected to the left and right ends of the front portion E, and the flaps D1 and D2 connected to the left and right ends of the bottom portion D form the outer surfaces of the side portions. The flaps D11 and D21 connected to the flaps D1 and D2, respectively, are folded at substantially 90 degrees to form a part of the upper surface. Furthermore, flaps D12 and D22 are respectively connected to the flaps D1 and D2, and the flaps overlap a part of the rear surface portion C on the inside. Further, the flaps D11 and D21 are connected to flaps D13 and D23 which overlap with a part of the front surface portion E on the inside. With such a configuration, it is possible to disassemble (deploy) the storage unit with the roll stored.
[0017]
A further feature of the present invention is the harm caused by facilitating the disassembly of the storage section, that is, it is difficult to maintain the form as a box with a certain strength, and as a result, the quality of the stored rolls is reduced. It is to solve the problem that it becomes difficult to maintain. In the conventional packaging method, it was general that the packaging box was assembled beforehand in the structure of the packaging box, and then the rolls were stored. The storage unit is assembled in a state where the roll suspended in the state of being suspended by the suspension member is placed on the upper side (on the bottom surface portion D of the storage unit). At this time, the lid may be assembled in advance, or may be assembled at the same time or after the storage.
[0018]
Making it possible to assemble the storage unit with the suspended roll placed on the bottom surface D of the storage unit, that is, it is possible to disassemble the roll with the roll stored in the storage unit. However, if the storage unit is simply dismantled, it is difficult to maintain the storage unit as a box, and the lid unit cannot be put on the storage unit. Therefore, the packaging box of the present invention has a structure in which the storage section can maintain the form as a box with a certain strength. That is, it is necessary that the flaps D11 and D21 forming part of the upper surface and the front surface portion E are directly or indirectly connected. In the method for bonding, the bonding means is formed in one corrugated cardboard sheet forming the packaging box without using external means such as an adhesive or a clasp.

[0021]
The above-mentioned hook-shaped joints are preferably provided at positions near the tips of the respective flaps, and the hook-shaped joints are connected near the tips of the flaps D11 and D12 and the flaps D21 and D22, and the projections ( 1a, 1b) and the cutouts (2a, 2b) are combined near the roots of the flaps D11 and D22 (near the folding ruled lines shown by dotted lines), and the flaps D11 and D21 are repelled. It can be effectively prevented from trying to return to. As a result, it is possible to maintain the form of the storage section as a box with a certain degree of strength, and it becomes easier to cover the storage section with the lid.
[0022]
Flaps D13 and D23 are further connected to flaps D11 and D21. By inserting the flaps D13 and D23 between the front part E and the roll in the suspended state by the suspended member, the fixing of the flaps D11 and D21 is further strengthened.
[0023]
Next, assembly of the lid will be described. The flaps B1 and B2 connected to the left and right ends of the upper surface B respectively form the outer surfaces of the side surfaces of the lid, and the flaps B11 and B21 connected to the flaps B1 and B2, respectively, are folded by approximately 180 degrees to cover the lid. The inner surface of the side portion of the portion is formed. The connecting portion between the flaps B1 and B11 and the connecting portion between the flaps B2 and B21 are provided with two perforated cut lines 7a so that the rebound of the folded flaps B11 and B21 is suppressed and the bending position is accurate. 7b are provided at intervals slightly wider than the thickness of the cardboard sheet.
