Description

  The present invention relates to a packaging box that can store commodities of different sizes without generating useless space.

  In recent years, various products can be ordered and purchased by telephone or the Internet. And a purchaser may purchase goods which are not packed with a packaging box, or two or more goods simultaneously. For this reason, a mail-order company that sells this type needs to prepare a dedicated packaging box for transportation.

  However, since each product has a different size, a plurality of types of packaging boxes including a shape in plan view are required. The preparation of a plurality of types of packaging boxes is problematic in that the cost is high and the storage space is also required. If a large packaging box is prepared, it is of course possible to accommodate small items, but the wasteful space created inside must be filled with cushioning material, which increases the cost. A storage space for cushioning materials is required.

  Therefore, there is a demand for a packaging box that can change the form after assembly. As prior art document information relating to such a packaging box, there is the following.

Japanese Patent No. 3432209

  This Patent Document 1 describes a packaging box including a 12-side preformed panel having a strip shape and an extension portion provided continuously with upper and lower edges of the 4-side preformed panel. Specifically, each preformed panel has the same width extending in the vertical direction, is provided so as to be continuous in the horizontal direction, and a crease is provided in each boundary portion. Each preformed panel is provided with an auxiliary crease at a position having the same dimensions as the width of the preformed panel from the upper and lower end edges. Thereby, the square-shaped lid | cover structure part enclosed by the crease | fold is each formed in the upper-lower end of each preforming panel.

  Further, the extension portion is provided at upper and lower edges of a first preformed panel located at one end, an adjacent second preformed panel, a seventh preformed panel located at an intermediate portion, and an adjacent eighth preformed panel. It is connected and a crease is provided at a boundary portion with each panel. These extensions have a protrusion with the same dimensions as the width of the preformed panel. Thereby, square-shaped lid components are further formed on the upper and lower ends of the first, second, seventh and eighth preformed panels.

  Furthermore, a pair of creases extending respectively diagonally are provided in all the lid constituent parts including the lid constituent part which is the extension part.

  As a result, the first sealed state in which the walls are each constituted by three consecutive preformed panels, and the walls are respectively constituted by two opposing preformed panels and four opposing preformed panels. In a two-sealed state, a third sealed state in which walls are formed by a preformed panel on one surface and a preformed panel on five surfaces facing each other can be achieved.

  However, this packaging box can change the dimensions in the lateral direction (width and depth), but the deformable dimensions are uniquely defined by the width of each panel. That is, when the preformed panels are formed to have different widths, a state where the end cannot be closed occurs. Therefore, the shape of the plan view is based on a square shape, and the pair of walls can be adjusted only in equal parts such as a width of 2/3, a width of 1/3, and the degree of freedom in adjusting dimensions is low. There is.

  This invention is made in view of the conventional problem, and makes it a subject to provide the packaging box which can improve the freedom degree of the design change which concerns on the dimension adjustment of planar view shape.

In order to solve the above-mentioned problems, the packaging box of the present invention includes a pair of end walls and side walls, and a packaging box in which flaps constituting a lid are connected to upper and lower end edges of the packaging boxes. A folding line for adjusting the horizontal dimension extending in the vertical direction over the upper and lower end edges of the pair of flaps, and a boundary line with the end wall and the folding line for adjusting the horizontal dimension on each flap continuous to the end wall. the fold for folding lines consisting of lead ruling of Ru extending at an inclination angle of approximately 45 degrees from the intersection toward the side edge provided, wherein a first closure a folded state at the boundary portion between the flap and the wall, the end wall and a continuous the flaps, to allow the second sealing state width is wide depth narrower than occluded the first closure state the flap is folded along a transverse dimension adjusting bending lines and folding for folding lines, folding lines for the folding Provided The point angle of the flap has a configuration in which a notch extending toward fold line for the fold.

  According to this packaging box, the first sealed state folded at the boundary between each wall and the flap, and the second sealed case where the end wall is folded along the lateral dimension adjusting folding curve and the continuous flap is folded along the folding folding curve. Depending on the state, the dimensions in the lateral (width and depth) direction can be changed. In addition, these sealed states can be reliably closed even if the lateral dimension is changed by the flaps continuously provided on the end wall and the flaps provided continuously on the side wall. And when adjusting the horizontal dimension in the second sealed state, the entire outer shape of the blank is also changed by changing the position of the folding curve for adjusting the horizontal dimension, and accordingly changing the position of the folding curve for folding. do not have to. Therefore, the degree of freedom related to dimensional adjustment can be improved.

Further, the point angle of the flap provided with folding lines for folding write, since the provided cut-out portion extending toward fold line for folding write, the workability can be improved folding the flap along a fold line for folding.

  In the packaging box of the present invention, since the shape can be changed to a sealed state depending on the shape required for the product to be stored, the number of packaging boxes to be prepared and the amount of cushioning material can be reduced, and the cost can be reduced. Can be planned. Further, these sealed states can be reliably closed even if the formation position of the lateral dimension adjustment folding curve changes. Therefore, the degree of freedom related to dimensional adjustment can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 5 show a packaging box according to a first embodiment of the present invention. This packaging box is provided with a pair of end walls 10A, 10B and side walls 11A, 11B, and flaps 14A, 14B-17A, 17B are connected to the upper and lower edges of these, respectively, and these flaps 14A, 14B-17A, 17B. Thus, two types of sealing, that is, a first sealed state closed by the first sealed state and a second sealed state having a narrower depth and a wider width than the first sealed state are made possible.

  This packaging box is formed by punching a well-known corrugated cardboard sheet having a corrugated shin between the front and back sheets as a single continuous blank shown in FIG. 5 using a well-known paper punching device (not shown). The predetermined part is pasted and formed by gluing.

  As shown in FIG. 5, the packaging box blank is provided such that each pair of end walls 10 </ b> A and 10 </ b> B and side walls 11 </ b> A and 11 </ b> B having a rectangular shape are alternately and linearly continuous. Among these, the margin part 12 for adhering to the end wall 10B located in the right end part is continuously provided at the edge of the side wall 11A located in the left end part. In each of the boundary portions of the end walls 10A and 10B, the side walls 11A and 11B, and the adhesive margin 12, a folding line 13 is provided which is formed with a ruled line so as to compress the thickness.

  On the end walls 10A and 10B, upper inner flaps 14A and 14B are connected to the upper end edge, and lower inner flaps 15A and 15B are connected to the lower end edge. The side walls 11A and 11B have upper outer flaps 16A and 16B connected to the upper end edge, and lower outer flaps 17A and 17B connected to the lower end edge. A folding line 18 similar to the above is provided between the flaps 14A, 14B to 17A, 17B and the continuous walls 10A, 10B, 11A, 11B. Note that the projecting dimensions of these flaps 14A, 14B to 17A, 17B are set to approximately half of the lateral dimensions of the end walls 10A, 10B. Further, these flaps 14A, 14B to 17A, 17B are formally defined as an upper side and a lower side, but there is no upper and lower limit in actual use.

  In the present embodiment, the lateral dimension adjustment extending in the vertical direction from the upper and lower edges of the inner flaps 14A, 14B, 15A, 15B to the end walls 10A, 10B and the inner flaps 14A, 14B, 15A, 15B that are continuous in the vertical direction. A working curve 19 is provided. These lateral dimension adjustment folding lines 19 are formed with a ruled line so as to compress the wall thickness, and extend in the vertical direction at the same interval from the folding lines 13 located on the left side in the end walls 10A and 10B. It is provided as follows. Thereby, in the assembly state shown in FIG. 1, it is comprised so that it may become a line symmetrical position with respect to the centerline extended longitudinally in end wall 10A, 10B. However, in the present embodiment, the second sealed state is set so that the width of the end walls 10A and 10B is halved with respect to the first sealed state. It is provided so as to be located at the center of 10A and 10B.

  Further, the inner flaps 14A, 14B, 15A, and 15B have 45 to the left side edge from the intersection of the folding line 18 and the lateral dimension adjusting folding line 19 that are boundary lines with the continuous end walls 10A and 10B. A folding fold line 20 is provided that extends at an inclination angle of degrees. The folding line 20 for folding is composed of a folding line formed with a ruled line so as to compress the thickness, and a lead ruled line in which cutting lines are provided at predetermined intervals on the folding line.

  Further, the inner flaps 14A, 14B, 15A, and 15B are provided with a notch 21 that extends to the folding curve 20 at the tip corner located in the direction in which the folding curve 20 extends. The notch 21 is formed by an L-shaped square chamfer including a first cutting line extending in the vertical direction over the folding line 20 for folding and a second cutting line extending in the horizontal direction from the intersection.

  When setting the dimensions of the packaging box having the above-described configuration, first, the lateral dimensions S1 and S2 of the end walls 10A and 10B and the side walls 11A and 11B are set based on the necessary planar view shape (width and depth) and height. In addition to setting, a vertical dimension T is set. Thereafter, a position (width dimension S3) for forming the lateral dimension adjusting folding line 19 is set based on the second necessary planar view shape. And the folding line 20 for folding is formed in each inner flap 14A, 14B, 15A, 15B, and the notch part 21 is formed.

  Here, the blank of the said structure is a general general purpose packaging box, if the folding curve 19 for horizontal dimension adjustment, the folding curve 20 for folding, and the notch part 21 are not formed. And this general-purpose packaging box can be manufactured by a general-purpose processing machine such as a flexogluer which has low equipment costs and high mass productivity, rather than a die cutter with high equipment costs and low mass productivity. Therefore, if the packaging box of this embodiment forms only the partial type | mold which forms the folding curve 19 for horizontal dimension adjustment, the folding curve 20 for folding, and the notch part 21, it is possible to produce by the said flexogluer.

  Next, the usage method of the said packaging box is demonstrated.

  First, when this packaging box is in the first sealed state where the end walls 10A and 10B are wide (depth), the end walls 10A and 10B and the side walls 11A and 11B are moved along the folding line 13 as shown in FIG. These are spread out to form a square cylinder. Next, the lower inner flaps 15A and 15B are bent with respect to the end walls 10A and 10B, and then the lower outer flaps 17A and 17B are bent. And the front-end | tip part of lower outer flap 17A, 17B which faced is stuck by sticking means, such as an adhesive tape (not shown). Thereafter, the upper inner flaps 14A and 14B are bent with respect to the end walls 10A and 10B, the upper outer flaps 16A and 16B are bent, and the tip portions of the upper outer flaps 16A and 16B that are similarly abutted are attached with an adhesive tape. To wear. Thereby, as shown in FIG. 2, a packaging box can be made into a 1st sealing state.

  On the other hand, when the end walls 10A and 10B are in the second sealed state where the width (depth) is narrow, as shown in FIG. 3, the end walls 10A and 10B are folded along the lateral dimension adjustment folding curve 19, and the folding curves 13, the side wall 11A is bent with respect to the end wall 10A, and the side wall 11B is bent with respect to the end wall 10B. Next, as shown in FIG. 4A using the upper inner flap 14A, the lower inner flap 15A is bent along the folding curve 20 so as to be overlapped inward. Similarly, after the lower inner flap 15B is bent along the folding curve 20, the lower outer flaps 17A and 17B are bent and closed. And while sticking an adhesive tape along the front-end edge of the lower outer flap 17B located in the surface side, the side edge of lower outer flap 17A, 17B is stuck with an adhesive tape. Similarly, the upper inner flaps 14A and 14B are folded inward along the folding curve 20, and the upper outer flaps 16A and 16B are folded and closed. And while sticking an adhesive tape along the front-end edge of the upper outer flap 16B, the side edges of the upper outer flaps 16A and 16B are stuck with an adhesive tape. Thereby, as shown to FIG. 4 (B), a packaging box can be made into the 2nd sealing state whose width | variety is wider than a 1st sealing state, and depth is narrow.

  In addition, in order to set it as a 2nd sealing state, the procedure which bends each flap 14A, 14B-17A, 17B can be variously changed according to an operator's wish.

  Thus, the packaging box of this embodiment includes the first sealed state bent at the boundary between the walls 10A, 10B, 11A, 11B and the flaps 14A, 14B-17A, 17B, the end walls 10A, 10B, and the inner walls. In the second sealed state in which the flaps 14A, 14B, 15A, and 15B are bent at the lateral dimension adjustment folding line 19 and the folding line for folding 20, the lateral dimension can be changed.

  Each sealed state can be reliably closed even if the width of the end walls 10A, 10B is changed by the outer flaps 16A, 16B, 17A, 17B connected to the side walls 11A, 11B. That is, these sealed states are not uniquely defined by the dimensions of the end walls 10A and 10B and the side walls 11A and 11B that are the first sealed state. And when adjusting the width of the end walls 10A, 10B in the second sealed state, the formation position of the lateral dimension adjustment folding curve 19 is changed, and accordingly the position of the folding folding curve 20 is changed, It is not necessary to change the entire outer shape of the blank only by changing the extension amount of the notch 21. Moreover, when performing such dimensional adjustment, as shown in FIG. 6, it is possible to easily cope with the problem by replacing only the flexogluer partial mold.

  In this way, the packaging box of the present invention can be in a sealed state with different lateral dimensions depending on the plan view required for the goods to be accommodated, so the number of packaging boxes to be prepared and the amount of cushioning material can be reduced. Cost reduction can be achieved. In addition, these sealed states can be reliably closed by the inner flaps 14A, 14B, 15A, 15B and the outer flaps 16A, 16B, 17A, 17B provided with the folding lines 20 for folding. Can be improved.

  Moreover, in this embodiment, since the notch part 21 is provided in inner flap 14A, 14B, 15A, 15B which forms the folding line 20 for folding, when it is set as a 2nd sealing state, the corrugated cardboard itself which is a raw material is used. Repulsion due to the waist can be suppressed, and the workability of folding the inner flaps 14A, 14B, 15A, 15B can be improved.

  7 to 13 show the packaging box of the second embodiment. In the second embodiment, as shown in FIG. 13, a pair of left and right lateral dimension adjustment folding curves 19A and 19B, folding folding curves 20A and 20B and cutout portions 21A and 21B are provided for the end walls 10A and 10B, respectively. By providing it, it is different from the first embodiment in that the lateral dimension can be adjusted in three stages.

  In the present embodiment, the dimension S4 between the lateral dimension adjusting folding curves 19A and 19B is set to be half the width (dimension S2) of the end walls 10A and 10B. Further, a dimension S5 between the lateral dimension adjustment folding lines 19A and 19A and the folding lines 13 and 13 that are boundaries between the side walls 11A and 11B located on the left side in the assembled state, and the lateral dimension adjustment folding curves. The dimension S6 between 19B and 19B and the folding lines 13 and 13 which are the boundary lines between the side walls 11B and 11A located on the right side in the assembled state is further half, that is, 1 / of the width of the end walls 10A and 10B. The dimension setting is 4. However, the settings of these dimensions S4, S5, and S6 can be changed as desired, and the dimensions S5 and S6 can be set differently.

  Further, in the present embodiment, the protrusion amount of the inner flaps 14A, 14B, 15A, 15B prevents the extension dimension of the notches 21A, 21B from becoming unnecessarily long and improves the workability during assembly. It is set short. However, the protruding amount is set longer than the dimensions S5 and S6 between the folding curves 19A and 19B for adjusting the horizontal dimension and the folding curves 13 and 13 adjacent to each other in the assembled state, and the exposed portion in the third sealed state described later. It is prevented from occurring.

  When this packaging box is in the first sealed state where the width (depth) of the end walls 10A, 10B is the widest, as shown in FIG. 7, the end walls 10A, 10B and the side walls 11A, 11B are moved along the folding line 13, These are spread so as to form a square cylinder. Next, after folding the lower inner flaps 15A and 15B with respect to the end walls 10A and 10B, the lower outer flaps 17A and 17B are bent, and the tips of the lower outer flaps 17A and 17B are attached with an adhesive tape. . Thereafter, the upper inner flaps 14A and 14B are bent with respect to the end walls 10A and 10B, the upper outer flaps 16A and 16B are bent, and the tip portions of the upper outer flaps 16A and 16B are attached with an adhesive tape. Thereby, as shown in FIG. 8, a packaging box can be made into a 1st sealing state.

  Further, when the end walls 10A and 10B have the second sealed state in which the width (depth) is narrowed by one step, for example, as shown in FIG. 9, the end walls 10A along one of the lateral dimension adjustment folding curves 19A and 19A. , 10B and the side walls 11A, 11B are bent along the folding line 13 with respect to the end walls 10A, 10B. Next, as shown in FIG. 10 (A) using the upper inner flap 14B, the lower inner flap 15A is folded along the folding folding curve 20A so as to overlap inwardly, and the lower inner flap 15B is folded. Bend along the folding line 20A. Thereafter, each of the lower outer flaps 17A and 17B is bent, and an adhesive tape is attached along the leading edge of each of the lower outer flaps 17A and 17B. Similarly, the upper inner flaps 14A and 14B are folded inward along the folding curve 20, and the upper outer flaps 16A and 16B are folded, and the adhesive tape is applied along the front edge of each upper outer flap 16A and 16B. Adhere. Thereby, as shown to FIG. 10 (B), a packaging box can be made into the 2nd sealing state whose width | variety is wider than a 1st sealing state, and depth is narrow.

  Further, in the case of the third sealed state in which the end walls 10A and 10B have the narrowest width (depth), as shown in FIG. 11, a pair of lateral dimension adjustment folding curves 19A without folding along the folding curves 13. , 19B, the end walls 10A, 10B are bent and widened to form a square cylinder. Next, as shown in FIG. 12A using the upper inner flap 14B, the lower inner flaps 15A and 15B are folded inward along the folding fold lines 20A and 20B, respectively, and then each lower outer flap is folded. 17A and 17B are bent, and both side edges thereof are adhered with an adhesive tape. Similarly, after folding the upper inner flaps 14A and 14B inward along the folding lines 20A and 20B, the upper outer flaps 16A and 16B are folded, and the leading edges thereof are adhered with an adhesive tape. Thereby, as shown to FIG. 12 (B), a packaging box can be made into the 3rd sealing state whose width | variety is wider and depth is narrower than a 2nd sealing state.

  In addition, in order to set it as the 2nd and 3rd sealing state, the procedure which bends each flap 14A, 14B-17A, 17B can be variously changed according to an operator's wish.

  Thus, in the packaging box of the second embodiment, the end walls 10A, 10B and the inner flaps 14A, 14B, 15A, 15B are provided with a pair of folding curves 19A, 19B for adjusting the horizontal dimension, folding curves 20A, 20B for folding, By providing the notches 21A and 21B, the horizontal dimension of the packaging box can be adjusted in three stages. And the adjustment range is not uniquely defined by the dimensions of the end walls 10A and 10B and the side walls 11A and 11B in the first sealed state, as in the first embodiment. It can be improved.

  In addition, the packaging box of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the above-described embodiment, the sealed state in which the end walls 10A and 10B have the narrowest width (the second sealed state in the first embodiment and the third sealed state in the second embodiment) is the same as the end walls 10A and 10B. Although the half dimension is set, of course, a dimension narrower than half can be set. In this case, since the outer flaps 16A, 16B, 17A, and 17B cross over the edges of the opposing side walls 11B and 11A in the sealed state, the outer flaps 16A, 16B, 17A, and 17B have folding folding curves extending in the lateral direction. It is preferable to fold and overlap in a substantially U shape.

  Moreover, in the said embodiment, although the external appearance applied to the packaging box which consists of a hexahedron, for example in the 1st sealing state, the packaging box etc. which provided the chamfering wall between end wall 10A, 10B and side wall 11A, 11B etc. The same applies. Of course, it is possible to form the chamfered wall in the second or third sealed state in which the shape in plan view is changed.
