Description

  The present invention relates to a method for manufacturing a storage box for a recording medium holding case such as a video cassette case or a DVD case.

  2. Description of the Related Art Conventionally, a flat box type storage box is known in which a top side is opened as a loading / unloading port for a recording medium holding case such as a video cassette case or a DVD case by a front part, a rear part, a pair of side parts and a bottom part. .

  This storage box has a front blank, a back, a pair of side faces, a bottom face, and an overlapping part that overlaps the back face of the front face and the back face of the bottom face in an assembled state on one unfolded blank. In the state where these are assembled and assembled, the overlapping portion is fixed by a stapler or glue.

  Since such a storage box is well known, it is not necessary to describe the patent document.

  By the way, in general, when this type of storage box is used, it is usual to hold the front and back portions with one hand with the loading / unloading port facing forward, and to insert / remove the recording medium holding case in that state. At this time, if the storage box does not have a certain amount of waist when the recording medium holding case is not inserted, the opening of the inlet / outlet becomes narrow when grasped with one hand, making it difficult to insert or remove the recording medium holding case.

  Therefore, conventionally, a paper material such as cardboard having a certain thickness (for example, a thickness of about 1.5 mm to 3 mm) is used for the unfolded blank, and this is assembled into the box shape described above. For this reason, it was difficult to assemble due to the thickness, and the material cost increased. In addition, when there is no printing on the surface, there is no offset printing machine that prints thick paper material as described above. There is a problem that it is necessary to carry out a process of attaching paper or a film, which further increases material costs and manufacturing costs.

  The present invention pays attention to such a problem, and an object of the present invention is to provide a method for manufacturing a storage box for a recording medium holding case that simultaneously reduces material costs and manufacturing costs.

  In order to achieve this object, the present invention takes the following measures.

  That is, the method for manufacturing a storage box for a recording medium holding case according to the present invention includes a front portion, a rear portion, a pair of side portions and a bottom portion, and the top portion is placed in and out of a recording medium holding case such as a video cassette case or a DVD case. A flat box-shaped storage box body opened as a mouth, a folded piece of the storage box body that is folded back from the longitudinal edges of the access port to the front side and the back side of the back side; and the storage box body A storage box comprising an insert piece that is folded inward from the back surface portion and inserted into a gap between the front portion and the folded piece is assembled and manufactured from a single unfolded blank having a fold line formed at a required location. In doing so, the front and back portions are folded to the facing position via the bottom surface while the folded piece is folded inside the front and back portions. A first folding step of bending, and the insertion piece in the gap between the front part and the folded piece while bending the side part at a position to close the side opening partially surrounded by the front part, the back part and the bottom part The storage box is temporarily assembled by the second folding step of inserting the sheet, and then the insertion piece is pulled out from the gap between the front part and the folded piece to form a glue surface, and again the gap between the front part and the folded piece It is characterized by performing the finishing process which pastes an insertion piece on the back surface of a front part by inserting in.

  According to such a manufacturing method, the process from folding to temporary assembly and finishing can be completed in a short time through simple folding work and gluing work. In addition, the front part and the back part are doubled by the folded piece, and the insertion piece is raised from the back part and inserted between the front part and the folded piece and adhered, so that the front part, the back part, and the side part are attached. Since the bottom portion and the bottom portion are inseparably integrated, it is easy to secure a required strength even if the development blank is thinned, and it is possible to reduce the material cost and further simplify the operation.

  In particular, the storage box includes an overlapping portion that is folded back from the side surface portion to the back surface side of the bottom surface portion, and the overlapping portion is provided from the side surface portion to the back surface side of the bottom surface portion during the second folding process. If folded, the overlapping part is positioned between the front part and the back part on the back side of the bottom part, and the bottom part is reinforced, with almost no increase in work procedures. It becomes difficult for the portion to deform in the direction of narrowing the space between the front portion and the back portion, and the strength of the storage box can be effectively increased.

  The storage box includes an overlapping portion that is folded back from the bottom surface to the back surface side of the side surface portion, and the overlapping portion is folded from the bottom surface portion to the back surface side of the side surface portion during the second folding process. Even so, the same effects as described above can be obtained.

  Further, the storage box includes an auxiliary folding piece that is folded back from the both edges in the short direction of the outlet / inlet to the back side of the side surface portion, and the step of folding the auxiliary folding piece after the first folding step is performed. For example, the auxiliary folding piece is positioned in a state of being stretched between the front portion and the back portion, so that the entrance / exit between the front portion and the back portion is not easily deformed in a narrowing direction, and the strength of the storage box is made more effective. It is possible to prevent the recording medium holding case from being hindered.

  In addition, before the first folding step, one surface of the double-sided tape is attached in advance to the position to be the glue surface of the development blank, and the release paper is removed from the other surface of the double-sided tape in the finishing step. If the adhesive surface is formed by peeling, the adhesive surface can be instantly and appropriately formed at a required location, and the working time can be further shortened.

  Alternatively, in the finishing step, if the insertion piece is pulled out from the gap between the front portion and the folded piece, and glue is attached to the drawn insertion piece, the place where no glue is required at the assembly stage Therefore, it is possible to form a reliable glue surface.

  Furthermore, even if the development blank is thinned, the required strength is ensured in the storage box, so that the printing process for applying the required print to the development blank itself can be performed in advance. In addition to simplifying the manufacturing process and reducing the manufacturing cost, the design can be diversified, such as printing inside the box.

  Furthermore, if the punched hole is punched out in the portion along the longitudinal direction of the loading / unloading port in a state of being folded in advance with respect to the development blank, when the storage box is assembled, the loading / unloading port of the recording medium holding case Since a semicircular recess is formed at the edge along the longitudinal direction, the recording medium holding case can be smoothly put in and out without touching the storage box when the recording medium holding case is put in and out.

  Since the present invention has the configuration described above, the required strength can be ensured even with a thin material with reduced cost, and assembly can be completed in a short time by simple bending work and gluing work, reducing the material cost and reducing the manufacturing cost. It is possible to provide a storage box for a recording medium holding case that realizes reduction at the same time.

FIG. 6 is an explanatory diagram and FIG. 6 is a diagram showing an outline of the entire assembly process.

  This storage box is used for storing a recording medium holding case (not shown) such as a video cassette case or a DVD case.

  First, the storage box A shown in FIGS. 1 and 6 is a flat box type in which the top side is opened as a loading / unloading port B of the recording medium holding case by the front part 1, the back part 2, the pair of side parts 4 and the bottom part 3. Storage box body A, folded pieces 11 and 12 folded back from the longitudinal edges of the insertion / exit port B of the storage box body A to the back side of the front part 1 and the back part 2, and the storage box body A An insertion piece 5 that is folded inward from the bottom surface portion 3 and inserted into a gap between the front surface portion 1 and the folded piece 11, and an overlapping portion that is folded back from the side surface portion 4 to the back surface side of the bottom surface portion 3. 6 and auxiliary folding pieces 7 which are folded back to the back side of the side surface portion 4 from both edges in the short direction of the loading / unloading port B.

  The developed blank shown in FIG. 2 is a Thomson process that simultaneously processes punching and pushing a single sheet of paper material (e.g., a paperboard having a thickness of about 0.5 mm to 0.7 mm) that is thick enough to pass through an offset printing press. The folding part 11, the front part 1, the bottom part 3, the back part 2, the folding part 12 are formed adjacent to each other in one direction, and the short part of the back part 2 is formed in the short direction. The side surface portion 4 and the insertion piece 5 are formed adjacent to each other in the direction orthogonal to the one direction on both edges, and the bottom surface portion 3 is formed when the storage box A is assembled on one side in the short side direction of the both side surface portions 4. The overlapping portion 6 is formed adjacent to one side in contact, and the auxiliary folded piece 7 is formed adjacent to the other side. The fold line is formed in advance by a press or the like at the boundary of each region such as the front portion 1 and the bottom portion 3. One surface of the double-sided tape 15 (see FIG. 5) is pasted in advance on the surface side of the insertion piece 5 at a position to be the glue surface 15a, and the release paper is peeled off from the other surface at the end of the assembly. It is comprised so that the paste surface 15a may be formed.

  Next, the process of assembling the storage box A from the developed blank will be described. This process includes a process of temporarily assembling the storage box A and then gluing and finishing a required portion.

  The temporary assembly process includes a first folding process shown in FIG. 3 and a second folding process shown in FIG.

  In the first folding step, the folded pieces 11 and 12 are folded back to the back surfaces of the front surface portion 1 and the back surface portion 2 as indicated by arrows in FIG. 6, while the front surface portion 1 and the back surface portion 2 are bottom surfaces in the back surface direction of the bottom surface portion 3. The front part 1 and the back part 2 are bent so as to face each other through the bottom part 3 so as to be perpendicular to the part 3.

  In the second folding step, first, the insertion piece 5 and the overlapping portion 6 are folded in the back direction as indicated by arrows in FIG. The insertion piece 5 is inserted into a gap Δ (see FIG. 6) between the front portion 1 and the folded piece 11, and the overlapping portion 6 is formed on the bottom portion 3. Stack on the back.

  In the finishing step, as shown in FIG. 5, one surface of the double-sided tape 15 that once pulled out the insertion piece 5 inserted into the gap Δ between the front portion 1 and the folded piece 11 and adhered to the surface side of the insertion piece 5. Then, the release paper is exposed to form the glue surface 15a, and the insertion piece 5 is again inserted into the gap Δ between the front portion 1 and the folded piece 11 to adhere the back surface of the insertion piece 5 and the front portion 1.

  In addition, although the auxiliary | assistant folding | turning piece 7 folds in the back surface side of the side part 4, the timing to fold may be any step of each process shown in FIGS. The assembly of the storage box A shown in FIG. 1 is completed through the above steps.

  As described above, the manufacturing method of the storage box A according to the present embodiment is configured such that the front portion 1 and the rear portion 2 are connected to the bottom portion 3 while the folded pieces 11 and 12 are folded inside the front portion 1 and the rear portion 2. The front part 1 while folding the side part 4 at a position to close the side opening partially surrounded by the front part 1, the rear part 2 and the bottom part 3 The storage box A is temporarily assembled by the second folding step of inserting the insertion piece 5 into the gap Δ between the folded pieces 11 and 12, and then the insertion piece 5 is connected to the front portion 1 and the folded pieces 11 and 12. The glue surface 15a is formed by being drawn out from the gap Δ and is inserted into the gap Δ between the front portion 1 and the folded pieces 11 and 12 again to perform a finishing process in which the insert piece 5 is glued to the back surface of the front portion 1. For which Unishi, can be completed in a short period of time through a temporary set, until a simple folding work and gluing, finishing work from folding. Moreover, the front part 1 and the back part 2 are doubled by the folded piece, and the insertion piece 5 is raised from the back part 2 and inserted between the front part 1 and the folded pieces 11 and 12 and adhered. Because the front part 1, the back part 2, the side part 4 and the bottom part 3 are inseparably integrated, it becomes easy to ensure the required strength even if the paper of the development blank is a thin material with reduced cost, Work can be further simplified while reducing material costs. Therefore, even if the storage box A is gripped with one hand with the front and rear portions 1 and B facing forward, and the recording medium holding case is put in and out in this state, It is possible to avoid the disadvantage that the opening is narrowed and it is difficult to insert and remove the recording medium holding case.

  In addition, since the overlapping portion 6 is folded back from the side surface portion 4 to the back surface side of the bottom surface portion 3 during the second folding process, the overlapping portion 6 can be formed in the bottom surface portion without increasing the work procedure. 3 is positioned in a state of being stretched between the front part 1 and the back part 2 and the bottom part 3 is also reinforced, so that the bottom part 3 is deformed in a direction to narrow the space between the front part 1 and the back part 2. It becomes difficult, and the strength of the storage box A can be effectively increased.

  Further, after the first folding step, the auxiliary folding piece 7 is folded back to the back side of the side surface portion 4 from both edges in the short direction of the top portion B, so that the auxiliary folding piece 7 becomes the front portion 1. Since it is positioned in a state of being stretched between the back surface portion 2 and the back surface portion 2, it becomes difficult for the entrance B between the front surface portion 1 and the back surface portion 2 to be narrowed, and the strength of the storage box A is increased more effectively. It is possible to prevent troubles in inserting and removing the recording medium holding case.

  In particular, one surface of the double-sided tape 15 is pasted in advance at a position that becomes the paste surface 15a of the unfolded blank, and the release paper is exposed from the other surface of the double-sided tape 15 in the finishing step to paste the paste surface 15a. Therefore, the glue surface 15a can be instantly and appropriately formed at the required location, and there is no need to re-glue or fix with a stapler as in the prior art. Beauty is planned.

  The specific configuration of each unit is not limited to the above-described embodiment.

  For example, in the above-described embodiment, the overlapping portion 6 is adjacent to the side that contacts the bottom surface portion 3 when the storage box A is assembled among the one sides of the side surface portions 4 in the short direction. It is also possible to form it so as to be adjacent to both sides in the hand direction so that the overlapping portion is folded back from the bottom surface portion 3 to the back surface side of the side surface portion 4 in the second folding process.

  In addition, since a printing process for performing a required print on the unfolded blank itself can be performed in advance, a print film becomes unnecessary, so that not only the manufacturing process is simplified, but also the manufacturing cost can be reduced. . Moreover, the integral storage box A which consists of one expansion | deployment blank which does not require a back film and a cover is the top part B used as an opening part by folding and assembling, even if it is single-sided printing, and the inside of a box. Since the folded portions 11 and 12 can also be printed, it is easy to enjoy detailed design. Of course, it does not preclude coating or masking a thin film on the development blank as long as the basic effects of the present invention are achieved.

  Further, when punching out the unfolded blank, a hole that is a part of the top portion B, for example, a midpoint of a side where the front portion 1 and the folded piece 11 or the back portion 2 and the folded piece 12 are in contact, is made a center point. May be. When the storage box A is assembled in this state, a semicircular recess is formed at the edge along the longitudinal direction of the inlet / outlet B of the recording medium holding case, so that the storage box is not touched when the recording medium holding case is put in and out. The recording medium holding case can be inserted and removed smoothly.

  Further, in the finishing process, if the insertion piece is pulled out from the gap between the front portion and the folded piece, and glue is attached to the drawn insertion piece, a place where no glue is required at the assembly stage Therefore, it is possible to form a reliable glue surface.

  Furthermore, the manufacturing method of this storage box A can provide storage boxes corresponding to all sizes by changing each size of one development blank.

  Other configurations can be variously modified without departing from the spirit of the present invention.
