Description

  The present invention relates to a packaging box, and more specifically, to a packaging box that can be determined at a glance that it has been opened at the time of purchase, and can be re-sealed with an insertion flap.

  In recent years, there has been a situation in which a foreign object is mixed in a merchandise department and looks as if unopened. In order to prevent this, various tamper-proof packaging boxes have been proposed.

  For example, Japanese Patent Application Laid-Open No. 2003-137277 (Patent Document 1) discloses a packaging box having a structure in which left and right inner flaps are provided in an opening at the top of a box body so that both inner flaps are bonded to the back of the top surface. It is disclosed. In this packaging box, the left and right inner flaps are cut when the top surface is opened.

  Japanese Patent Laid-Open No. 2003-327242 (Patent Document 2) is provided with a cut line on a crease line that partitions the top surface and the insertion flap, a break line is provided on the front surface of the box body, and the part surrounded by the break line There is disclosed a packaging box provided with an insertion piece extending upward. In this packaging box, since the insertion piece is inserted into the cut on the crease line that partitions the top surface and the insertion flap, the breaking line is broken when the top surface is opened.

  In JP 2004-269031 A (Patent Document 3), an insertion flap is provided on the top surface so as to be cut, and a cut is provided at a connection portion between the top surface and the insertion flap, and one of the left and right inner flaps is provided. Discloses a packaging box provided with a protrusion that can be inserted into the cut. In this packaging box, since the projection of the inner flap is inserted into the cut, the insertion flap is cut off when the top surface is opened.

  Japanese Patent Application Laid-Open No. 2003-137274 (Patent Document 4) has a top surface that closes the upper opening of the box body, and an outer flap that is glued to the back surface of the top surface, and the top surface includes a scheduled cutting portion. Disclosed packaging boxes are disclosed. In this packaging box, the planned cutting part is cut and opened.

  In Japanese Patent Laid-Open No. 2003-165529 (Patent Document 5), notches are provided in the vicinity of the both ends of the fold line that divides the top surface and the insertion flap and in the center thereof, and inserted into the left and right inner flaps at the cuts at the both ends. A packaging box is disclosed in which a protrusion is provided and an insertion piece to be inserted into the central cut of the crease line is extended to the opening of the box body.

  In this packaging box, since the protrusions provided on the left and right inner flaps are inserted into the cuts, the lid is firmly fixed, and when opening, the inserted piece is damaged or the box is broken and tampering is easily determined.

JP 2003-137277 A JP 2003-327242 A JP 2004-269031 A JP 2003-137274 A JP 2003-165529 A

  However, it is necessary to glue the top surface and the inner flap in the packaging box of Patent Document 1 and the top surface and the outer flap in the packaging box of Patent Document 4, and the assembly is troublesome.

  On the other hand, in the packaging boxes of Patent Document 2, Patent Document 3, and Patent Document 5, it is necessary to insert the insertion piece at each cut, and there is a problem in that it takes time to assemble.

  And in these packaging boxes, after opening, the packaging box is destroyed or the insertion flap is cut, so there is a problem that the opening at the top of the box body cannot be closed again on the top surface .

  The present invention has been made in view of the above-described background art, and an object of the present invention is to reduce tampering during assembly and to prevent tampering by allowing the top opening of the box body to be closed again on the top surface. Is to provide a packaging box.

  Therefore, in the present invention, the front end of the insertion flap is provided with a cutting flap provided in the insertion flap so as to be detachable in a state of being partially connected thereto, and the cutting flap is opened to the insertion flap. It is made to insert in the state folded in V shape inside.

  In this packaging box, when opened, the cutting flap folded in a V shape with respect to the insertion flap attempts to move upward in a state folded in a V shape, but this movement is suppressed by the inner flap. Further, as the insertion flap moves upward, the break flap folded in a V-shape is about to open, but its movement is hindered by the articles stored in the packaging box. As a result, an upward force is applied from the insertion flap and a half downward force is applied from the breaking flap to the connection portion between the insertion flap and the cutting flap, so that the connection portion is cut.

  Therefore, in the packaging box of the present invention, whether or not the cutting flap is appropriately cut depends on the relationship between the article and the packaging box, for example, the distance between the article and the inside of the box body, the size of the insertion flap and the size of the inner flap. The size and shape of the rupture flap are determined so that these effects are exhibited.

  The packaging box of the present invention can be easily assembled without gluing at the time of assembly or without inserting the insertion piece into the cut. Further, when the top surface is opened at the time of opening, it is immediately known that the broken flap has been excised and opened. And since the insertion flap is provided even after opening, it can be resealed.

  The packaging box of the present invention is a type of packaging box in which an insertion flap is inserted between the top edge of the top surface and the front inner surface of the box body, and is V-shaped inside the opening so as to be separable from the distal end of the insertion flap. It is a packaging box provided with a breaking flap that is folded into two, and the breaking flap is cut and removed by lifting the top surface when opened. In this packaging box, when the top surface is lifted by the opening operation, the breaking flap is lifted in a state of being folded in a V shape with respect to the insertion flap, but the movement of lifting the breaking flap is hindered by the inner flap. On the other hand, the movement to open the break flap folded in a V shape is hindered by the stored article. In the packaging box of the present invention, the size and shape of the breaking flap are determined so that such an action is exhibited. Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of a packaging box 1 according to an embodiment of the present invention, and FIG. 2 is a development view of the packaging box 1. In the developed view, a mountain fold line that is mountain-folded on the back side of the drawing is indicated by a one-dot chain line. The packaging box 1 includes a box body 10, a top surface 21 that serves as a lid for the opening 11 at the top of the box body 10, and left and right opening edges adjacent to the opening edge provided with the top surface 21. The inner flap (the left inner flap 24 and the right inner flap 25) and four bottom flaps 27 serving as lids for the lower opening of the box body 10 are provided. The box body 10 is produced from four continuous side surfaces 26 and one margin piece 28. The packaging box 1 is assembled from a single piece of paper 20 produced in the state shown in the developed view by punching or the like. The paper piece 20 is made of a flexible paper or plastic sheet. In the following, the surface where the front face of the insertion flap can be seen during assembly is the front surface, the one located on the front side is the front, the left-right direction with respect to the front surface is the width direction, and the direction perpendicular to the width direction ( The longitudinal direction will be described regardless of the longitudinal direction or the vertical direction. Moreover, about each flap, the edge which is distant from the crease line with a box main body is demonstrated as a tip edge.

  The top surface 21 is provided at the upper edge of the side surface 26 (the opening edge on the back side of the opening 11) located on the back surface during assembly, and is mountain-folded along the crease line 14. An insertion flap 22 is provided at the tip of the top surface 21 and is folded at a crease line 13. The insertion flap 22 has substantially the same width as the inner width of the upper opening 11 of the box body 10. The illustrated insertion flap 22 is manufactured such that the corner of the tip is processed into an arc shape and the width of the tip edge is shorter than the length of the crease line 13 with the top surface 21.

  A breaking flap 23 is provided at the tip of the insertion flap 22 so as to be separable from the insertion flap 22. This breaking flap 23 is provided in the insertion flap 22 in a state where it is partially connected to the insertion flap 22 and the other part is cut off. In the packaging box 1 shown in FIG. 1, a breaking flap 23 is provided via a breaking line 12 such as a sewing machine line. The breaking flap 23 is cut off at the breaking line 12 at the time of opening, and serves as a mark indicating that it has been opened. The breaking flap 23 is folded at the breaking line 12 when the packaging box 1 is assembled, and is inserted into the box body 10 while being folded in a V shape with respect to the insertion flap 22 inside the opening of the box body. The rear end corner of the breaking flap 23 is processed in an arc shape so that the breaking flap 23 shown in the figure overlaps with the corner of the front end of the insertion flap 22 when folded.

  The position where the breaking flap 23 is provided is preferably a position where the force for cutting the breaking flap 23 is as large as possible. This position varies depending on the relationship with the stored article 30, for example, the shape of the article 30, the shape of the cap 31, the distance from the inner surface of the box body 10, and the sizes of the inner flaps 24 and 25. In the packaging box 1 shown in the first embodiment, the front end edge (the upper edge in a state of being folded in a V shape) 23 a is made to be substantially the same width as the width of the box body 10.

  In the packaging box 1 of the present invention, the breaking flap 23 is separated from the insertion flap 22 by the force received by the breaking flap 23 from the inner flap 24 and the inner flap 25 and the force received from the article 30 by contacting the article 30. In order to increase the force received from the inner flaps 24, 25, the position near the attachment position of the inner flaps 24, 25 to the opening edge, that is, the vicinity of the crease line 15 of the left inner flap 24 or the crease line of the right inner flap 25. It is preferable to provide a breaking flap 23 in the vicinity of 16.

  On the other hand, in order to receive a force from the article 30, the breaking flap 23 needs to be in contact with at least the article 30. In order to receive a large force from the article 30, it is preferable that a region in contact with the article 30 is wide, and it is desirable that the article 30 is reliably contacted. By the way, in the packaging box 1 for cosmetics, an article 30 composed of a cylindrical cap (a cap whose head is circular when viewed in plan) and a cylindrical main body is often stored. FIG. 3 shows a state in which an article 30 consisting of a cap 31 having a circular head and a cylindrical main body 32 is stored as a representative article to be stored. The position where the article 30 and the cutting flap 23 come into contact is the position where the article 30 is closest to the inner surface of the box body 10, that is, the vicinity of the center of the box body 10 in the width direction. Accordingly, the breaking flap 23 is provided near the center of the box body 10 in the width direction. As shown in the figure, when the inner width of the box body 10 and at least the width of the front edge 23a of the breaking flap 23 are set to be substantially the same, the left inner flap 24 and the right Since force is applied from both of the inner flaps 25, and the force is reliably applied from the head of the cap 31 of the article 30 (in some cases, the shoulder of the main body 32 or the side surface of the main body 32) in the center of the breaking flap 23, It can be said that it is a preferable shape and size as the shape of the breaking flap 23.

  The breaking line 12 needs to be cut at the time of opening. In order for the breaking flap 23 to be surely cut off at the time of opening, it is desirable that the length of the breaking line 12, that is, the connection area between the insertion flap 22 and the breaking flap 23 is as short as possible. However, if it is too short, there is a high possibility that it will be cut off during assembly or sealing. Therefore, for example, if the corner of the front end of the insertion flap 22 or the rear end corner of the breaking flap 23 or both are cut into an arc shape as shown in the drawing, the length of the breaking line 12 can be shortened.

  It is necessary that the breaking line 12 does not lose the force for returning the breaking flap 23 folded in a V shape to the expanded state, that is, the force for opening the breaking flap 23. Otherwise, when the insertion flap 22 is inserted, the breaking flap 23 does not come into contact with the article 30. As a result, it is considered that the force by the article 30 is not applied to the breaking flap 23 and the breaking line 12 is not cut. From such a viewpoint, it is preferable that the paper-like piece 20 has appropriate flexibility, and the mountain fold is not completely mountain-folded, and it is desired that the paper-shaped piece 20 be folded to an extent that is not sufficient.

  The left inner flap 24 and the right inner flap 25 are mountain-folded at crease lines 15 and 16 which are attachment portions to the opening edge, respectively. The left inner flap 24 and the right inner flap 25 have substantially the same size, the length of the leading edge 24a of the left inner flap 24 is shorter than the length of the crease line 15, and the leading edge 25a of the right inner flap 25 Is made in a substantially trapezoidal shape with a length shorter than that of the crease line 16. At this time, the width at the front edge is slightly shorter than the width of the opening 11, and the front edges of the inner flaps 24, 25 overlap almost the entire region in the width direction. The front edges of the left and right inner flaps 24, 25 are located in the vicinity of the front opening edge of the box body 11, and the insertion flaps are disposed between the front edges of the left and right inner flaps 24, 25 and the front opening edge of the box body 11. Both 22 and the breaking flap 23 folded in a V shape are inserted.

  In the packaging box 1 of the present invention, when the article 30 is stored, the breaking flap 23 folded in a V shape inside the opening slightly opens, and the leading edge 23a of the breaking flap 23 is below the back of the inner flaps 24, 25. To position. At the time of opening, the breaking flap 23 folded as the top surface 21 is lifted is also lifted. The upward movement and the movement of the breaking flap 23 caused by this movement are opened in the packaging box 1. Utilization that the stored article and the left and right inner flaps 24, 25 block. That is, as shown in FIG. 4, for example, in the state where the substantially cylindrical article 30 having the cap 31 having a circular head shown in FIG. The front end 23a of the flap 23 is positioned on the lower surfaces of the inner flaps 24 and 25, and the breaking flap 23 is held in a V-shaped open state with respect to the insertion flap 22 while being in contact with the cap 31. When the top surface 21 is lifted to open the packaging box 1, the insertion flap 22 moves upward, and the breaking flap 23 moves upward while keeping the V shape. However, since the inner flaps 24 and 25 are positioned at the leading edge 23a of the breaking flap 23, the leading edge 23a of the breaking flap 23 hits the inner flaps 24 and 25, and the breaking flap 23 cannot move further upward. On the other hand, as the breaking flap 23 moves upward, the breaking flap 23 tries to open in a direction in which the angle between the breaking flap 23 and the insertion flap 22 increases, but the breaking flap 23 opens greatly because it is in contact with the article 30. This movement is also limited. When the top surface 21 is further lifted, due to the restriction, a force that pulls upward from the insertion flap 22 is applied to the breaking line 12, and a force that goes downward from the breaking flap 23 to the breaking line 12. Will be added. As a result, the breaking line 12 is broken and only the breaking flap 23 is cut ((c) in the figure). Then, the insertion flap 22 is pulled upward from between the front edges of the inner flaps 24, 25 and the front opening edge of the opening 11, and the seal is opened ((d) in the figure).

  In the present invention, it is considered that the opening movement of the breaking flap 23 is hindered by the article 30 as described above, but the action that the article 30 hinders the opening movement of the breaking flap 23 is to break the insertion flap 22. The flap 23 is used not to maintain the V-shape when inserted into the opening 11 of the box body 10 but to mean that it cannot be opened freely. That is, in a state where the article 30 is not stored, the breaking flap 23 is not restricted by the article 30 and thus opens widely, and the breaking flap 23 is opened without being cut. The present invention uses the article 30 that is housed so that the breaking flap 23 does not greatly open with respect to the insertion flap 22 as described above, and generates a so-called downward force on the breaking flap 23.

  In the packaging box 1 of the present invention, only the breaking flap 23 is broken by the operation as described above. Accordingly, the shape of the breaking flap 23, the length L2 of the breaking flap 23, and the length L1 of the insertion flap 22 are determined by the article 30 (main body and cap) stored in the packaging box 1 so that such an effect is exhibited. It is designed as appropriate according to the size and shape of 31). In particular, since the breaking flap 23 folded in a V shape needs to come into contact with the article 30 and its movement needs to be restricted, a length L2 that comes into contact with the article 30 when inserted is required.

  If the gap between the article 30 and the lower surfaces of the inner flaps 24, 25 is excessively widened, the movement of the breaking flap 23 to be opened may not be suppressed. This is because the breaking flap 23 enters between the article 30 and the inner flaps 24, 25, and the breaking flap 23 becomes parallel to the inner flaps 24, 25, so that no force is applied to the breaking flap 23. Accordingly, in the present invention, it is also necessary that the gap between the article 30 and the lower surfaces of the inner flaps 24 and 25 is not too large. Of course, when the insertion flap 22 is lifted, even if the breaking flap 23 enters between the article 30 and the lower surfaces of the inner flaps 24 and 25, and the breaking flap 23 opens widely, the movement of the breaking flap 23 is caused by the movement of the article 30. As a result of being constrained between the inner flaps 24 and the lower surfaces of the inner flaps 24 and 25, a half downward force is applied to the breaking line 12 from the breaking flap 23, and the breaking line 12 may be cut. The packaging box 1 of the present invention can perform such an action.

  Further, since the left and right inner flaps 24 and 25 must prevent the breaking flap 23 folded in a V shape from moving upward, the leading edge 25a of the right inner flap 25 is provided with the left side face 26 and the left inner flap. The function may not be fulfilled if it is separated from the 24 crease lines 15 (the width becomes shorter). Similarly, if the front edge 24 a of the left inner flap 24 is separated from the right side surface 26 and the crease line 16 of the right inner flap 25, the function may not be performed. Moreover, like the conventional packaging box having the insertion flap 22, it is necessary to prevent the insertion flap 22 from which the breaking flap 23 has been removed from floating. For this purpose, the front end of the left inner flap 24 is positioned in the vicinity of the crease line 16, and the front end of the right inner flap 25 is positioned in the vicinity of the crease line 15, thereby increasing the overlap width of both the inner flaps 24, 25. It is preferable to reduce the floating of the flaps 24 and 25. This is because the force for breaking the breaking line 12 increases as the distance by which the inner flaps 24 and 25 are lifted is smaller than the distance by which the insertion flap 22 is lifted.

  On the other hand, if these functions can be achieved, the shape of the inner flaps 24 and 25 may be determined so that the left and right inner flaps 24 and 25 do not overlap, and one inner flap of the left inner flap 24 and the right inner flap 25 may be determined. May be provided. However, in this case, the left and right inner flaps 24 and 25 may be easily opened. As a result, the rupture flap 23 folded in a V shape easily opens, and the rupture flap 23 is not cut off, and from above between the front edge of the inner flaps 24, 25 and the front opening edge of the box body 11. It is possible to come out. In the packaging box 1 of the first embodiment, the left and right inner flaps 24, 25 are formed in a symmetrical shape, so that the left inner flap 24 and the right inner flap 25 overlap at approximately the center position of the box body 10. This makes it easier to balance the left and right when opening.

  In this packaging box 1, after opening as mentioned above, since the fracture | rupture flap 23 is cut | disconnected, it turns out that it opened at first glance. In addition, even after opening, the top surface 21 is provided with the insertion flap 22 that is mountain-folded with respect to the top surface 21 so that it can be sealed again.

  As described above, in the packaging box 1 of the present invention, the breaking flaps 23 are cut by preventing the opening of the breaking flaps 23 in which the left and right inner flaps 24 and 25 and the stored articles 30 are folded in a V shape. What is necessary is just what the shape of the insertion flap 22 and the shape of the fracture | rupture flap 23 are not ask | required.

  The insertion flap 22 shown in FIG. 5 is produced in a rectangular shape having a width length substantially equal to the width of the top surface 21. Further, the breaking flap 23 is produced in a substantially rectangular shape having a width shorter than the width of the insertion flap 22, and the insertion flap is provided via a breaking line 12 provided at a substantially central position of the insertion flap 22. 22 is provided at the tip. The breaking flap 23 may be a simple rectangular shape as illustrated, and the opening of the breaking flap 23 is suppressed by the article 30 stored in the packaging box 1.

  The breaking flap 23 shown in FIG. 6 is formed in a substantially concave shape in plan view, and has a rectangular cutout 23c at the center of the tip, and has protrusions 23b on both sides of the tip. The protruding portion 23b of the breaking flap 23 is restrained by the inner flaps 24, 25, and the upward movement of the breaking flap 23 is restrained. Further, the leading edge of the notch 23c of the breaking flap 23 comes into contact with the stored article 30, and the movement of the breaking flap 23 to be opened is prevented. Even the rupture flap 23 having such a shape may be used. Only the breaking flap 23 is cut by the same action as described above.

  In this way, the breaking flap 23 has a shape in which the upward movement is suppressed on the lower surfaces of the inner flaps 24 and 25 and the opening of the breaking flap 23 by the contact between the breaking flap 23 and the stored article 30 is suppressed. As long as it has.

  FIG. 7 is a developed view in which a part of a packaging box 1 according to still another embodiment of the present invention is broken. In the packaging box 1, only the vicinity of the left and right ends of the breaking flap 23 is connected to the insertion flap 22 through the breaking line 12. In this manner, the insertion flap 22 and the breaking flap 23 may be partially connected, and the remaining region may be provided as the cutting line 18 and the breaking flap 23 may be provided at the tip of the insertion flap 22. In this case, the region to be the breaking line 12 is preferably the left and right ends of the breaking flap 23 as shown in FIG. This is because the closer to the crease lines 15 and 16 of the inner flaps 24 and 25, the greater the force received from the inner flaps 24 and 25, the easier it is to cut them.

  FIG. 8 is a developed view in which a part of a packaging box 1 according to still another embodiment of the present invention is broken. In this packaging box 1, only the both ends of the breaking flap 23 are connected to the insertion flap 22 by a very short solid line, and a cut 19 in the width direction is provided at the center of the breaking flap 23. As described above, the breaking flap 23 may be provided at the front end of the insertion flap 22 by a combination of a narrow solid line and a wide cutting line without using the breaking line 12 such as a sewing machine line, so that both can be separated. . Although not shown, it is not necessary to provide the cut 19 as long as the two are separated. The breaking flap 23 and the insertion flap 22 may be provided with a part having a very short width, for example, a line close to a point, in the width direction, with the most part as the cutting line 18, and the two may be connected.

  FIG. 9 is a perspective view of a packaging box 1 according to still another embodiment of the present invention, and FIG. 10 is a development view of the packaging box 1. In the packaging box 1, only the right flap 25 is provided in the box body 10 by the crease line 16. The width of the breaking flap 23 is shorter than that of the insertion flap 22. The breaking flap 23 is provided in the vicinity of the crease line 16 which is an attachment site of the right flap 25. Also in the packaging box 1, when the top surface 21 is lifted at the time of opening, the breaking flap 23 tends to move upward, but the movement is suppressed by the inner flap 25. Further, the movement to open the breaking flap 23 is hindered by the stored article. For an article (not shown) having a cap that is rectangular in plan view, the packaging box 1 having such a breaking flap 23 may be used.

  As in the packaging box 1 of the sixth embodiment, if the structure is such that a large force is applied from the inner flap 25 to the leading edge 23a of the breaking flap 23 and the opening operation of the breaking flap 23 by the article 30 is suppressed, the left It does not matter even if any one of the inner flap 24 and the right flap 25 is provided.

  Needless to say, the present invention is not limited to the above-described embodiments, and various modifications can be considered. For example, in the above-described embodiment, the case where the breaking flap 23 is provided in the insertion flap 22 in the upper opening 11 of the box body 10 has been described. However, also in the case where the insertion flap is provided in the lower opening of the box body. The same applies.

  According to the present invention, there is provided a tamper-proof packaging box that can be seen at first glance by an assembling method similar to a conventional general packaging box having an insertion flap. In particular, it is possible to assemble without gluing the top surface and the inner flap or inserting an insertion piece. Moreover, even if it opens once, it can be resealed with an insertion flap.
