Description

  The present invention relates to a method for manufacturing a box member having a box body having an upper part opened to accommodate a product or a lid having a lower part opened to be externally fitted to the box body.

  Conventionally, as a packaging box for packaging products, a box body whose upper part is opened to accommodate the product and a cover body whose lower part is opened to be externally fitted to the box body are cut (punched) into a predetermined shape. Is formed by bending.

  Such a box body or lid is provided as a box member for constituting a packaging box. The box member includes a rectangular sheet portion having a rectangular shape in plan view, and both ends and both ends of the rectangular sheet portion. And four wall portions extending in a direction orthogonal to the rectangular sheet portion. Thereby, when the box member is the box body, the rectangular sheet portion is the bottom, the four wall portions constitute a peripheral wall erected on the outer periphery of the bottom, and the box member is the lid. In this case, the rectangular sheet portion becomes the top portion, and the four wall portions constitute a peripheral wall depending from the outer periphery of the top portion.

  By the way, since a packaging box wraps a product, a decorative property is required on the outer surface of the box body or the lid. Therefore, in general, printing is performed on the outer surface of the box body or lid, but it is not possible to give texture or three-dimensionality by printing. Some decorative sheets such as the above are attached to the outer surface of the rectangular sheet portion and the wall portion with an adhesive to enhance the decorativeness.

  However, as described above, when a decorative sheet is pasted using an adhesive, there is a problem that the characteristics of the decorative sheet are destroyed and the decorativeness and appearance are seriously impaired.

  That is, if the entire surface of the decorative sheet is affixed to the square sheet part or wall part with an adhesive, the entire decorative sheet becomes hard or adheres too much to the square sheet part or wall part as the adhesive hardens. Therefore, there is a problem that the texture of the decorative sheet is destroyed.

  Also, when multiple places on the decorative sheet are affixed to the square sheet or wall with an adhesive, the decorative sheet will adhere to the square sheet or wall while the adhesive is present. There is a problem that the part that does not float is floating from the rectangular sheet part or the wall part, and the appearance is deteriorated.

  Then, in view of such a situation, this invention makes it a subject to provide the manufacturing method of the member for boxes which can decorate with a decoration sheet well without destroying the characteristic of a decoration sheet.

  In the method for manufacturing a box member according to the present invention, a rectangular sheet portion having a square shape in plan view and four wall portions extending in a direction orthogonal to the rectangular sheet portion from both ends and both side ends of the rectangular sheet portion are decorated. In a method of manufacturing a box member, which is either a box body decorated with a sheet and having an upper part opened to accommodate a product, or a lid having a lower part opened to be externally fitted to the box body. A rectangular region having a shape, a pair of first extending regions extending from both ends of the rectangular region, a pair of second extending regions extending from the tip of each first extending region, and both ends of the rectangular region One having at least one surface decorated with a spread sheet having a pair of third extending regions extending from the pair and a fourth extending region extending from the tip of each third extending region The decorative sheet is shaped so that the other side faces one side of the unfolded sheet and has four corners. A sheet stacking step of overlapping so as to protrude from the second extension region and the fourth extension region, and a decorative sheet protruding from the second extension region and the fourth extension region to the second extension region and the fourth extension A sheet folding process that folds back to the other surface side of the unfolded sheet along the leading edge of the protruding area, and after the sheet folding process, the first extending area is bent at the boundary with the rectangular area to stand substantially perpendicular to the rectangular area After the first standing step and the sheet folding step, the second extending region is folded back to the other surface at the boundary with the first extending region, and the third extending after the sheet folding step. After the second standing step for folding the region at the boundary with the square region and standing at a right angle with respect to the square region, and the sheet folding step, the fourth extending region is connected to the other surface at the boundary with the third extending region. A second folding process for folding back to the side. The features. Here, “one side is decorated” is a concept that includes a single color or a plurality of colors as well as a pattern or design applied to one side of the decorative sheet. It is.

  According to the method for manufacturing a box member having the above-described structure, the decorative sheet protruding from the leading end of the second extending region and the leading end of the fourth extending region in the sheet folding step is folded back to the other surface side of the unfolded sheet. On the sheet, a ridge line by folding is formed along the leading end of the second extending region and the leading end of the fourth extending region, and each corner of the decorative sheet is in a state of facing the developing sheet.

  Then, in the first standing step and the second standing step, when the first extending region and the second extending region are erected so as to be substantially perpendicular to the rectangular region, the decorative sheet in which the four corners are folded back Is pulled between the corners at the diagonal positions, and the region facing the square region is in a moderately tensioned state. And in the first folding step and the second folding step, the second extending region overlaps the first extending region by folding the second extending region and the fourth extending region, and the fourth extending region is In this state, the third extension region is overlapped. As described above, the decorative sheet in which the four corners are folded is also pulled between the corners at the diagonal positions by folding the second extension region and the fourth extension region in this manner. The area facing the square area is in a moderately tensioned state.

  Then, when all of the first folding process, the second folding process, the first standing process and the second standing process are completed, the rectangular sheet part constituted by the square region and either one of both ends or both side edges of the rectangular sheet part Extending from the first extending region and the second extending region, and extending from either one of both ends or both ends of the rectangular sheet portion, the third extending region and the fourth extending A box member having a double wall portion formed with the exit region is completed. The box member is used as a box body whose upper part is opened or a lid body that is externally fitted to the box body so as to cover the upper part of the box body. Therefore, when each of the box main body and the lid body is constituted by the box member, the box body has a different size so that the wall portion of the lid body can be fitted or fitted to the wall portion of the box main body. Two will be produced.

  As described above, according to the present invention, since the entire surface or a plurality of locations of the decorative sheet are not attached to the rectangular sheet portion or the wall portion, the decorative sheet adheres unevenly to the outer surface of the rectangular sheet portion or the wall portion, or is cured. Thus, the exterior can be satisfactorily decorated without destroying the characteristics of the decorative sheet.

  As one aspect of the present invention, the spread sheet further includes a fifth extension region extending in the same direction as the third extension region from both ends of each first extension region, and before the first standing step, A third folding step of folding the first extension region at the boundary with the rectangular region so as to overlap the square region; and a first extension region where the tip side of the fifth extension region is connected to the fifth extension region. A fourth folding step of folding back each fifth extending region to the other surface side so as to extend in the same direction as the extending direction, a second folding step and a second folding step, and a third folding step; After the fourth folding step, the fifth extension region further includes a fifth extension region sticking step of sticking at least one surface of the tip portion of the fifth extension region to the other surface of the third region. You may make it perform a 2nd standing up process with a 1st standing up process after an adhesion process.

  In this way, in the fourth folding step, each of the fifth extending regions extends in the same direction as the extending direction of the first extending region to which the fifth extending region is connected. After the extension region is folded back to the other surface side, in the fifth extension region sticking step, at least one surface of the tip portion in the fifth extension region is attached to the other surface of the third region. Therefore, by performing the second standing step together with the first standing step in this state, the fifth extending region is extended at the boundary with the first extending region while the fifth extending region folded back in the fourth folding step is extended. The first extension region and the third extension region stand up by bending. That is, by raising one of the first extension region and the third extension region, the other is pulled or pushed by the fifth extension region to stand.

  And both sides of the decorative sheet corresponding to the first extension region and the second extension region (both sides including a pair of corners in a diagonal position protruding from the tip of the second extension region in the sheet arranging step) By going through the first folding step and the third folding step, the first extended region and the second extended region are involved. Therefore, after the fifth extension region sticking step, both sides of the decorative sheet (both sides including the pair of corner portions) are in a state of covering the fifth extension region. Thereby, when performing the 2nd standing up process with the 1st standing up process as mentioned above, the part which had covered the 5th extending area of the decoration sheet changes the posture of the 3rd extending area and the 5th extending area. Accordingly, the state is sandwiched between the third extension region and the fifth extension region. Therefore, as a result of hiding the extra portion of the decorative sheet, the appearance is good.

  As another aspect of the present invention, the sheet folding step preferably includes a sticking step of sticking a corner portion of the decorative sheet folded on the other surface side of the unfolded sheet to the other surface. In this way, the portion exposed to the outside of the decorative sheet is not attached to the unfolded sheet, and the positioning of the decorative sheet and the unfolded sheet can be ensured at an early stage, so that the subsequent process is smooth. Can be done.

  As another aspect of the present invention, the adhering step may be applied to the spread sheet via a double-sided pressure-sensitive adhesive tape that has been previously attached to a region including at least the corners of the other surface of the decorative sheet. . If it does in this way, a decoration sheet can be stuck on a development sheet smoothly and reliably.

  According to the method for manufacturing a box member according to the present invention, it is possible to achieve an excellent effect that the exterior can be nicely decorated with the decorative sheet without destroying the characteristics of the decorative sheet.

  The decoration sheet 11 is appropriately made of materials according to the decoration, for example, Japanese paper, watermark paper, fancy paper, Masasen paper, semi-paper, paper, tang paper, stencil paper, dyed stencil paper, stencil paper, stencil paper, and Japanese alphabet. Blowing paper, cloud paper, ink-washed paper, gold-silver foil paper, resin sheets, etc. can be employed.

  As shown in FIG. 4, the decorative sheet 11 is cut into a square shape in a plan view. When the decorative sheet 11 is superimposed on the development sheet 10, the rectangular area 100, the first extension area 101 a, and the third extension area are displayed. All areas 101c are set to a size that overlaps without any shortage. Specifically, when four corners P1, P2, P3, and P4 are arranged on two axes X and Y that pass through the center of the rectangular region 100 perpendicular to both ends and both side ends of the rectangular region 100 ( 3), the size is set so as to overlap all of the rectangular region 100, the first extending region 101a, and the third extending region 101c. That is, when the four corners P1, P2, P3, and P4 are aligned on the two axes X and Y passing through the center of the rectangular region 100, all four sides are the first extension region 101a and the third extension. The size is set so as to be located outside the exit area 101c.

  And the decorative sheet 11 which concerns on this embodiment is a double-sided adhesive tape in the area | region containing at least the corner | angular part of the other surface on the opposite side of one surface (surface which becomes the outer surface of the box member 1) to which the pattern etc. were given. Tb is stuck. The double-sided adhesive tape Tb is formed in a band shape, and is provided along each side of the decorative sheet 11 so as to be L-shaped at the corners.

  Next, the method to manufacture the box member 1 using the expansion | deployment sheet | seat 10 and the decoration sheet | seat 11 of the said structure is demonstrated.

  First, as shown in FIG. 5A, the decorative sheet 11 is opposed to the unfolded sheet 10, the other surface is opposed to one surface of the unfolded sheet 10, and the four corners are the second extension region 101b. And it overlaps so that it may protrude from the 4th extension area | region 101d (sheet | seat overlap process). That is, when the back surface of the decoration sheet 11 is overlapped with the development sheet 10, the four corners P1, P2, P3, and P4 of the decoration sheet 11 are positioned on two axes X and Y passing through the center of the development sheet 10. Deploy.

  And as shown in FIG.5 (b), the decoration sheet 11 which protruded from the 2nd extension area | region 101b and the 4th extension area | region 101d is followed along the front-end | tip of the 2nd extension area | region 101b and the 4th extension area | region 101d. The sheet is folded back to the other surface side of the unfolded sheet 10 (sheet folding process). And the other surface (back surface) of the corner | angular part of the decoration sheet 11 is partially affixed on the other surface of the expansion | deployment sheet | seat 10 in connection with turning up the corner | angular part of the decoration sheet | seat 11. FIG. In this embodiment, since the double-sided pressure-sensitive adhesive tape Ta is adhered to the other surface of the decorative sheet 11 so as to include a corner, the release sheet is peeled off from the double-sided pressure-sensitive adhesive tape Tb in advance, so that the decorative sheet 11 By simply turning the corner, the corner is stuck to the spread sheet 10 (sticking step).

  In the present embodiment, the corner portion reaches the first extension region 101a in a state in which the corner portion of the decorative sheet 11 on the axis X extending in the extension direction of the first extension region 101a is folded. On the other hand, in the state where the corner portion of the decorative sheet 11 on the axis Y extending in the extending direction of the third extending region 101c is folded, the corner portion remains in the fourth extending region 101b. Therefore, by peeling off the release paper of the double-sided pressure-sensitive adhesive tape Ta attached to the second extension region 101b in advance, the corner portion (folded portion) of the decorative sheet 11 is not the self-double-sided pressure-sensitive adhesive tape Tb. Affixed to the center of the double-sided adhesive tape Ta in the exit area 101b. Therefore, the double-sided adhesive tape Ta in the second extension region 101b is still in a state where nothing is stuck on both sides of the corner (folded portion) of the decorative sheet 11, and the double-sided adhesive tape Ta in the third extension region 101b is It will be in the state where nothing has stuck yet over the full length.

  Thereafter, as shown in FIG. 6A, the second extension region 101b is folded back to the other surface side at the second ruled line L2 (boundary with the first extension region 101a) (first folding step). In this embodiment, since the double-sided pressure-sensitive adhesive tape Ta is adhered to the second extension region 101b, the release paper of the double-sided pressure-sensitive adhesive tape Ta is peeled off in advance, and the second extension region 101b is defined as the second ruled line L2. The second extension region 101b (actually, the corner portion of the decorative sheet 11 wound around the second extension region 101b) is attached to the first extension region 101a. In addition, since the double-sided adhesive tape Ta in the second extension region 101b is not yet attached to both sides of the corner portion of the decorative sheet 11 as described above, the second extension region 101b is folded back. Thus, as described above, the first extension region 101a and the second extension region 101b are bonded to each other via the double-sided adhesive tape Ta.

  By folding back the second extension region 101b in this way, the decorative sheet 11 is also folded in the same manner as the second extension region 101b, and the corners attached to the unfolded sheet 10 are the first extension region 101a. It is interposed between the second extension region 101b. Further, since the second extension region 101b is on both sides of the square region 100, the decorative sheet 11 is pulled outward by folding the second extension region 101b along the second ruled line L2, and the square region 100 and The corresponding area will be tense.

  And in this embodiment, since the 5th extension area | region 102 is provided in the expansion | deployment sheet | seat 10, after folding the 2nd extension area | region 101b (after a 1st folding | turning process), as shown in FIG.6 (b). Each fifth extension region 102 is extended to the sixth ruled line so that the front end side of the fifth extension region 102 extends in the same direction as the extension direction of the first extension region 101a to which the fifth extension region 102 is connected. Fold back to the other surface side at L6 (fourth folding step).

  Thereafter, as shown in FIG. 7A, the first extended region 101a is folded at the first ruled line L1 (boundary with the rectangular region 100) so as to overlap the rectangular region 100 (third folding step). By doing in this way, the decorative sheet 11 is also folded similarly to the 1st extension area | region 101a.

  Thus, by folding back the first extension region 101a at the first ruled line L1, the tip of the fifth extension region 102 folded back at the sixth ruled line L6 overlaps with the third extension region 101c. In this state, the tip of the fifth extension region 102 is attached to the other surface of the third extension region 101c (fifth extension region attaching step). In this embodiment, since the double-sided adhesive tape Ta is affixed to the third extending region 101c, the release paper is peeled off from the double-sided adhesive tape Ta before the first extending region 101a is folded at the first ruled line L1. Thus, the front end portion of the fifth extension region 102 is attached to the third extension region 101c via the double-sided adhesive tape Ta in conjunction with turning back the first extension region 101a at the first ruled line L1. (Fifth extension region pasting step).

  After that, as shown in FIG. 7B, the first extension region 101a is bent at the first ruled line L1 (boundary with the rectangular region 100) to stand up at a substantially right angle with respect to the rectangular region 100 (first standing step). ) And the third extending region 101c is bent at the third ruled line L3 (boundary with the rectangular region 100) to stand substantially perpendicular to the rectangular region 100 (second standing step). In the present embodiment, as described above, the tip end portion of the fifth extension region 102 folded back at the sixth ruled line L6 is attached to the third extension region 101c. The fifth extension region 102 is folded at the fifth ruled line L5 while the fifth extension region 102 folded back at the sixth ruled line L6 is expanded so as to follow the standing of the 101a (first standing step) ( It will return to the original extended state).

  Along with this, the third extension region 101c to which the tip of the fifth extension region 102 is stuck is pulled by the fifth extension region 102 and automatically stands up (second standing step). . When the third extension region 101c is erected, the fifth extension region 102 is bent at the fifth ruled line L5 so as to follow the erection of the third extension region 101c (second erection process). On the other hand, the fifth extension region 102 folded back at the sixth ruled line L6 expands (returns to the original extension state). Along with this, the first extension region 101a is pushed by the fifth extension region 102 and automatically stands up (first standing step).

  As described above, when the first extending region 101a is bent and raised at the first ruled line L1, the decorative sheet 11 is bent similarly when the third extending region 101c is bent and raised at the third ruled line L3. Become. In the present embodiment, the second extending region 101b is folded back along the second ruled line L2 before the first extending region 101a is raised (before the first standing step). Along with raising the extension area 101a, the second extension area 101b is also raised. Thereby, the 1st extension area | region 101a and the 2nd extension area | region 101b form double wall part 3a, 3b.

  Furthermore, before raising the first extension region 101a and the third extension region 101c, by folding back the second extension region 101b and then folding back the first extension region 101a at the first ruled line L1, Since the decorative sheet 11 is in a state of covering the fifth extension region 102, the first extension region 101a and the third extension region 101c are erected (the second erection step is performed together with the first erection step). In addition, the portion (excess part of the decoration sheet 11) that covers the fifth extension region 102 of the decoration sheet 11 is changed to the third extension region 101c and the fifth extension region 102 in accordance with the posture change. The state is sandwiched between the extension region 101 c and the fifth extension region 102. Thereby, as a result of hiding the excess part of the decorative sheet 11, the appearance is good.

  Moreover, since each of the 1st extension area | region 101a and the 3rd extension area | region 101c exists in the both sides of the square area | region 100, if the 1st extension area | region 101a and the 3rd extension area | region 101c are bent, the decoration sheet 11 will be outside. The region corresponding to the square region 100 is tensioned. In the present embodiment, since the first extended region 101a folded at the first ruled line L1 is raised, the tension on the decorative sheet 11 tends to be weakened with the rising of the first extended region 101a. As described above, by pulling back the second extension region 101b, the decoration sheet 11 is sufficiently pulled, and the decoration sheet 11 is maintained in a tension state.
