Description

  The present invention relates to a packaging box that can accommodate products having different sizes and products having different quantities without generating a 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, each product may have a different size. Moreover, even if it is the same size, the quantity ordered may differ. Therefore, packaging boxes having a plurality of sizes (shapes and volumes) 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 on such a packaging box, there is the following.

Japanese Utility Model Publication No. 57-167016

  This patent document describes a packaging box in which a pair of first lateral dimension adjustment folding lines and a pair of second lateral dimension adjustment folding lines are provided on a side wall. In this packaging box, the side wall is bent along the first horizontal dimension adjusting fold line and overlapped with the adjacent end wall, whereby the width of the side wall is changed and the volume can be changed. In addition, a flap continuous with each side wall is provided with a break line having a perforation shape in order to separate unnecessary portions by changing the width.

  However, in the packaging box of this patent document, since the adjustment part of the side wall folded inside protrudes elastically in the sealed state, the accommodation workability of the product is poor and the accommodation state is not good. Moreover, since it is necessary to break the unnecessary portion of the flap, there is a problem that the sealing workability is poor.

  The present invention has been made in view of conventional problems, and it is an object of the present invention to provide a packaging box that can improve the workability of goods and can be well accommodated in a sealed state.

  In order to solve the above-described problems, a 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 the upper and lower end edges of each of the side walls and the continuous flaps. A first horizontal dimension adjustment fold line extending in the vertical direction from the side end to a position of about 1/6 of the horizontal width, and a vertical direction from the first horizontal dimension adjustment fold line to a position of about 1/6 of the horizontal width. A second horizontal dimension adjustment fold line extending in the vertical direction, and a third horizontal dimension adjustment fold line extending in the vertical direction from the second horizontal dimension adjustment fold line to a position of about 1/3 of the horizontal width. The side wall can be changed to a width of about 2/3 by folding the side wall and the flap so as to overlap each other along the second horizontal dimension adjustment folding line, and the second and third horizontal dimension adjustment folding lines. By folding each side wall and flap along Are the possible changes constituting the side wall about one third of the width.

  In this packaging box, when it is used in a state where the volume is the largest, the side wall is not folded in any of the lateral dimension adjusting fold lines, and the respective sealed flaps are folded into the end wall and the side wall. . When the packaging box is used in a volume of about 2/3, the side wall is partially folded into the first and second lateral dimension adjustment folding lines, and each flap is bent with respect to the end wall and the side wall. The second sealed state. Further, when the packaging box is used at a volume of about 1/3, the side wall is partially folded along the second and third lateral dimension adjustment fold lines so that each flap is placed on the end wall and the side wall. The third sealed state is bent.

  And according to this packaging box, when storing goods inside the second and third seals with a reduced volume, since the flaps continuous with the side walls are also folded together, the ridges due to the folding Then the bent state is fixed. Therefore, in the conventional example, the folded portion protrudes toward the accommodation space when the product is accommodated, which hinders the accommodation operation. However, it is possible to prevent such a problem from occurring. And in a sealed state, since a folding part is fixed in the state where it overlapped reliably on the upper and lower sides, a favorable accommodation state can be maintained reliably. In addition, since it is not necessary to cut off unnecessary portions, the sealing workability can be improved.

In this packaging box, the first lateral dimension adjustment fold line has a fold line formed so as to compress the thickness of the side wall, and a plurality of cutting lines extending along the fold line at a predetermined interval. It is preferable to form the lead ruled line or the reverse folding line formed so as to compress the thickness of the side wall from the outer surface of the side wall.
Further, the second lateral dimension adjustment folding line is formed by a lead ruler having a folding line formed so as to compress the thickness of the side wall, and a plurality of cutting lines extending along the folding line at a predetermined interval. It is preferable to configure.
In this way, the repulsive force in the folded state can be further reduced.

  In the packaging box of the present invention, since the flaps that are continuous with the side wall are also folded together, it is possible to prevent the folded portion from protruding toward the storage space when storing the product, and to prevent the storage operation from being hindered. . And in a sealed state, since a folding part is fixed in the state where it overlapped reliably on the upper and lower sides, a favorable accommodation state can be maintained reliably. In addition, since it is not necessary to cut off unnecessary portions, the sealing workability can be improved.

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

  FIG. 1 shows a blank of a packaging box according to an 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 to 17A, 17B are connected to the upper and lower ends of the end walls, respectively. By making the horizontal dimension of 11B changeable, the capacity that can be accommodated can be changed.

  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. 1 by a known paper punching device (not shown). The predetermined part is pasted and formed by gluing.

  The blank of the packaging box is provided such that each pair of end walls 10A and 10B and side walls 11A and 11B 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.

  Upper end first flaps 14A and 14B are connected to the upper end edges of the end walls 10A and 10B, and lower first flaps 15A and 15B are connected to the lower end edges. The side walls 11A and 11B have upper second flaps 16A and 16B connected to the upper edge, and lower second flaps 17A and 17B connected to the lower 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. The projecting dimensions of the first flaps 14A, 14B, 15A, 15B that are continuous with the end walls 10A, 10B are set to be about 1/3 of the lateral width of the side walls 11A, 11B. Further, the projecting dimensions of the second flaps 16A, 16B, 17A, and 17B that are continuous with the side walls 11A and 11B are set to about ½ of the lateral width of the end walls 10A and 10B. The 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 dimensions extending in the vertical direction from the upper and lower edges of the second flaps 16A, 16B, 17A, and 17B to the side walls 11A and 11B and the second flaps 16A, 16B, 17A, and 17B that are continuous in the vertical direction. Adjustment folding lines 19A to 19C are provided in parallel. Among them, the first lateral dimension adjusting fold line 19A located in the vicinity of the end wall 10A is separated from the boundary line (fold line 13) with the first end wall 10A which is the side end of the side walls 11A, 11B. It is provided at a position about 1/6 of the horizontal width of 11B. Further, the second lateral dimension adjusting fold line 19B located at the center is provided at a position about 1/6 of the lateral width of the side walls 11A, 11B from the first lateral dimension adjusting fold line 19A. Further, the third lateral dimension adjusting fold line 19C is provided at a position about 1/3 of the lateral width of the side walls 11A and 11B from the second lateral dimension adjusting fold line 19B. The first and second folding lines 19A and 19B for adjusting the horizontal dimension have a folding line formed with a ruled line so as to compress the thickness of the side walls 11A and 11B, and a predetermined interval along the folding line. The lead ruler has a plurality of cutting lines extending. Further, the third lateral dimension adjusting fold line 19C is constituted by a folding line formed by ruled lines so as to compress the wall thickness from the inner surface side of the side walls 11A, 11B. As a result, between the folding line 13 and the first lateral dimension adjusting folding line 19A, a first folding part 20A having a lateral width of about 1/6 in the lateral width of the side walls 11A and 11B is formed. Further, between the first and second lateral dimension adjusting fold lines 19A and 19B, a second fold portion 20B having a lateral width of about 1/6 in the lateral width of the side walls 11A and 11B is formed. Further, a third folded portion 20C having a lateral width of about 1/3 of the lateral width of the side walls 11A, 11B is formed between the second and third lateral dimension adjusting folding lines 19B, 19C.

  The packaging box having the above-described configuration bends the first side wall 11A with respect to the first end wall 10A, and bends the second end wall 10B with respect to the second side wall 11B so as to overlap the end portion 12 and the end portion. The wall 10B is glued with an adhesive such as a vinyl acetate emulsion, and is delivered to a predetermined manufacturer in this state.

  And when using the said packaging box in the state with the largest volume, as shown to FIG. 2 (A) and (B), fold side wall 11A, 11B in any folding line 19A-19C for horizontal dimension adjustment. Without being bent, the first flaps 14A, 14B, 15A, 15B continuous to the end walls 10A, 10B are bent as inner flaps, and then the second flaps 16A, 16B continuous to the side walls 11A, 11B, as in the known cardboard box. , 17A, 17B are bent as outer flaps. And the front-end | tip of 2nd flap 16A, 16B, 17A, 17B which face | matched mutually is stuck by adhering means, such as an adhesive tape. Thereby, it can seal in the 1st sealing state shown to FIG. 2 (B).

  Further, when the packaging box is used in a volume of about 2/3, as shown in FIGS. 3A and 3B, the side walls 11A and 11B along the first lateral dimension adjustment folding line 19A. The side walls 11A and 11B are mountain-folded along the second lateral dimension adjustment folding line 19B. Then, the folding portions 20A and 20B located between the lateral dimension adjusting folding lines 19A and 19B are superimposed on the side walls 11A and 11B and the second flaps 16A, 16B, 17A and 17B. In this state, the second flaps 16A, 16B, 17A, and 17B that are continuous to the side walls 11A and 11B are bent as inner flaps, and then the first flaps 14A, 14B, 15A, and 15B that are continuous to the end walls 10A and 10B are outer flaps. Bend as. And the front-end | tip of 1st flap 14A, 14B, 15A, 15B which face | matched mutually is stuck by adhering means, such as an adhesive tape. Thereby, it can seal in the 2nd sealing state shown to FIG. 3 (B). The flaps 14A, 14B to 17A, 17B may be bent with the first flaps 14A, 14B, 15A, 15B as inner flaps, and then with the second flaps 16A, 16B, 17A, 17B as outer flaps.

  Further, when the packaging box is used in a volume of about 1/3, as shown in FIGS. 4A and 4B, the side walls 11A and 11B are taken along the second lateral dimension adjustment folding line 19B. And the side walls 11A and 11B are folded along the third lateral dimension adjusting fold line 19C. Then, the folding portions 20A and 20B and the folding portion 20C positioned between the lateral dimension adjusting folding lines 19B and 19C are superimposed on the side walls 11A and 11B and the second flaps 16A, 16B, 17A, and 17B. In this state, the second flaps 16A, 16B, 17A, and 17B that are continuous to the side walls 11A and 11B are bent as inner flaps, and then the first flaps 14A, 14B, 15A, and 15B that are continuous to the end walls 10A and 10B are outer flaps. Bend as. And the front-end | tip of the 1st flap 14A and the end wall 10B which were overlapped on the outermost side are stuck by sticking means, such as an adhesive tape. Thereby, it can seal in the 3rd sealing state shown to FIG. 4 (B).

  In addition, when storing the product in which only the lower flaps 15A, 15B, 17A, and 17B are stored, the folding portions 20A to 20C act so as to protrude inward due to the elasticity of the cardboard paper itself. However, in the present embodiment, the first and second lateral dimension adjustment folding lines 19A and 19B located on the inner surface side are constituted by lead rules that are less likely to generate repulsive force. Moreover, the bent state at the ridges is fixed by bending the lower second flaps 17A and 17B continuous to the side walls 11A and 11B. Therefore, as shown in FIG. 3A and FIG. 4A, the folding portions 20A to 20C do not protrude toward the accommodation space when the merchandise is accommodated, thereby preventing the accommodation operation from being hindered. And in the state which sealed upper flap 14A, 14B, 16A, 16B, since folding part 20A-20C is fixed in the state superimposed on the upper and lower sides reliably, a favorable accommodation state can be maintained reliably. In addition, since it is not necessary to cut off unnecessary portions, the sealing workability 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 first lateral dimension adjustment folding line 19A is constituted by a lead rule. However, since the bent state of this part is only folded inwardly, the thickness is compressed from the outer surface. Alternatively, it may be constituted by a folding line formed by dents in the opposite direction formed by ruled lines.

  Moreover, in the said embodiment, although the folding line 19A-19C for horizontal dimension adjustment was provided only from the end wall 10A side, and it was set as the structure superimposed on one end wall 10A side in an assembly state, one side is made into an end. While providing from the side of wall 10A and providing the other from the side of end wall 10B, you may comprise so that the overlapping part folded in the substantially diagonal may be located.
