Description

  The present invention relates to a packaging box for protecting an object to be packed during transportation or storage.

  When a product such as an image forming apparatus is transported or stored, an A-type packing box having a shape in which an opening of a box-shaped main body portion is opened and closed with a folding flap may be used. Since the A-type packing box is relatively inexpensive, it is generally widely used. However, in recent years, there is a tendency to reduce the size of the packing box in consideration of the space during storage and transportation, and the distance between the packing box and the product that has been secured 70 mm to 80 mm in the past is about 30 mm in recent years. It is getting shorter. For this reason, in such an A-type packaging box, it is difficult to put a hand in the gap between the packaging box and the product, and there has been a problem in unpacking work.

  On the other hand, when transporting and storing tall products, a vertically divided packaging box in which a box-shaped lower case with an open top and a box-shaped upper case with an open bottom is connected by a joint member is used. Sometimes it is done. After removing the joint member, the upper case and the outer peripheral surface of the product are exposed by pulling out the upper case, so that the product can be easily taken out. However, in such a vertically divided type packaging box, there is a part in which the upper case and the lower case partially overlap, and there is a problem that the material cost becomes high.

  Therefore, in Patent Document 1, in the A-type packaging box, perforations are formed on both sides of the side plate forming one side surface, and one side surface is opened by separating the side plate along the perforation when unpacking. A packaging box configured as described above has been proposed. Further, in Patent Document 2, a lid and a part of the front side plate continuous with the lid are provided so as to be separable along the perforation, and the lid and a part of the front side plate are separated at the time of unpacking. A packaging box that facilitates removal has been proposed.

Japanese Utility Model Publication No. 6-2702 Japanese Utility Model Application No. 7-5564

  However, in the packaging box described in Patent Document 1 and Patent Document 2, the side plate and the lid are separated at the time of unpacking, and thus cannot be reused. Further, in order to be able to separate the side plate and the lid, perforations are formed at the corners of the side plate and the lid. Thus, if a sewing machine surface is provided at a corner that greatly affects the strength of the packaging box, the strength of the packaging box may be reduced.

  In view of the above-described circumstances, an object of the present invention is to provide a packaging box in which a packaged item can be easily taken out even when the gap between the packaged box and the packaging box is narrow without reducing the strength.

  In order to achieve the above object, a packaging box of the present invention has a rectangular bottom plate and a side plate erected from four sides of the bottom plate, and a fold line at the upper edge of the main body having an open top surface. Each of the pair of opposing side plates and the flap connected to the upper edge of the side plate. A notch forming portion is provided at the corner, and the notch forming portion includes one or two cutting lines formed so as to intersect the folding line, and the cutting line and the folding line. A fold line extending along a part of the fold line at an intersection with the fold line, folding the flap at the fold line and folding it outward, and folding the both fold lines at the valley By means of this, at the corners of the flaps bent to the outside and the side plates, Characterized in that it is configured to the packaging material is graspable space is formed.

  By adopting such a configuration, even when the distance between the packaged item and the packaging box is narrow, a space is formed at the corner of the flap and the side plate by folding the flap outward, so that a hand can be passed from this space. The packaged object can be gripped, and the packaged object can be easily taken out. Furthermore, since there is no portion that can be separated from the main body and the flap when unpacking, strength reduction can be prevented and the packaging box can be reused.

  In the packaging box of the present invention, the notch forming portion includes two cutting lines formed so as to intersect the folding line, and an intersection between the two cutting lines and the folding line. A double fold line extending along the upper edge, an upper mountain fold line extending between the upper ends of the two cutting lines, and a lower mountain fold line extending between the lower ends of the two cutting lines, and the flap The fold line is folded at the fold line and folded outward, the both fold lines are folded at the valleys, and the upper fold line and the lower fold line are folded at the fold, and the flap folded outward and the It is good also as the structure comprised so that the space which can hold | grip a to-be-packaged object is formed in the corner | angular with a side plate.

  By adopting such a configuration, the mountain can be folded at the upper mountain fold line and the lower mountain fold line, so that a space can be easily formed. Moreover, since the shape of the space becomes a substantially rectangular parallelepiped shape, which makes it easy to put in a hand, it becomes easy to grip the object to be packed.

  In the packaging box of the present invention, the notch forming portion is formed along a fold line with one cutting line formed so as to intersect the fold line and an intersection of the cutting line and the fold line as one end. A fold line extending a predetermined distance, an upper mountain fold line extending between the other end of the fold line and the upper end of the cutting line, and the other end of the fold line and the lower end of the cutting line. A lower mountain fold line extending between the upper fold line and the upper mountain fold line and the lower mountain fold line. It is good also as a structure that the space which can hold | grip a to-be-packaged object is formed in the corner | angular of the said flap bent by the side and the said side plate by folding in a mountain.

  By adopting such a configuration, the mountain can be folded at the upper mountain fold line and the lower mountain fold line, so that a space can be easily formed. Moreover, since the number of cutting lines can be reduced, the strength reduction of the packaging box resulting from the provision of the cutting lines can be reduced.

  In the packing box of the present invention, the packaged object has a handle on an upper part of the opposite side surface, and the notch forming part is the side surface on which the handle of the packaged object is formed. Are formed at the corners of the side plate corresponding to the side plate and the flap connected to the side plate, and the two cutting lines are narrower toward the position corresponding to the handle of the packaged object. It is good also as a characteristic that it is formed.

  By adopting such a configuration, the space becomes narrower toward the inner side and the lower side, and is formed so as to be guided by the handle. Therefore, even if it is difficult to confirm the position of the handle, if the hand is put into the space, the handle is naturally guided to the position of the handle, so that the packaged item can be taken out more easily.

  According to the present invention, since an object to be packed can be gripped through the space, the object to be packed can be easily taken out even when the gap between the box to be packed and the packing box is narrow.

In the following description, the up / down / left / right and front / back directions indicate the up / down / left / right front / rear directions shown in the drawings.

  As shown in FIG. 1, the packaging box 1 includes a main body 2 having an upper surface opened, and an outer flap 3 and an inner flap 4 that seal the opening of the main body 2. The main body 2, the outer flap 3, and the inner flap 4 are formed of a packaging material such as cardboard. In this example, the object to be packed 20 is an image forming apparatus in which an image reading device is provided on the upper surface of a rectangular parallelepiped main body, and handles 21 are formed on the left and right side surfaces of the image reading device.

  As shown in FIG. 1, the main body 2 is erected from a rectangular bottom plate 2a, a pair of long side plates 2b erected from the opposing long sides of the bottom plate 2a, and an opposing short side of the bottom plate 2a. A pair of short side plates 2c. An outer flap 3 is connected to the upper edges of the pair of long side plates 2b via a fold line 6, and an inner flap 4 is connected to the upper edges of the pair of short side plates 2c via a fold line 6. Yes. After the pair of inner flaps 4 are folded at the folding line 6 and folded inward, the pair of outer flaps 2 are folded at the folding line 6 and overlapped on the upper surface of the inner flap 4, so that the opening of the main body 2 is opened. Sealed. A notch forming portion 10 is provided at each corner of the pair of short side plates 2c and the inner flap 4 connected to the upper edge of each short side plate 2c.

  As shown in FIG. 2, the notch forming portion 10 includes two cutting lines 11, both fold lines 12 extending along the fold line 6, and upper and lower mountain fold lines 13 and 14. The handle 21 of the packaged object 20 is formed so as to correspond to the position.

  The two cutting lines 11 are formed in a straight line between the short side plate 2 c and the inner flap 4 so as to intersect the folding line 6. The two cutting lines 11 are formed so that the distance between the cutting lines narrows downward and is symmetrical with respect to a line orthogonal to the folding line 6 in the front-rear direction. The distance between the two cutting lines 11 is about the width that can be inserted by the operator's hand, and the distance D1 between the upper ends of the two cutting lines 11 and the folding line 6 and the two cutting lines 11 The distance D2 between the lower end of the fold line and the folding line 6 is formed to be equal. The distances D1 and D2 are substantially equal to the distance from the upper surface of the packaged object 20 to the handle 21. The cutting line 11 includes a perforation that can be cut.

  Both fold lines 12 extend along the fold line 6 between the intersections of the two cutting lines 11 and the fold line 6, and can be valley-folded and mountain-folded.

  The upper mountain fold line 13 is formed in the inner flap 4 so as to extend in the front-rear direction between the upper ends of the two cutting lines 11. The lower mountain fold line 14 is formed so as to extend in the front-rear direction between the lower ends of the two cutting lines 11 in the short side plate 2c. The upper and lower mountain fold lines 13 and 14 are parallel to the fold line 6. The upper and lower mountain fold lines 13 and 14 are formed as ruled lines in which the inner flap 4 and the short side plate 2c are recessed from the inside, respectively.

  With such a configuration, the notch forming portion 10 has an inverted base surrounded by two cutting lines 11 and upper and lower mountain fold lines 13 and 14, as shown in FIG. 2A and FIG. It has a shape, and is defined by a fold line 12 into a portion 10 a on the short side plate 2 c side and a portion 10 b on the inner flap 4 side.

  A method for unpacking the packaging box 1 having the above configuration will be described. First, the outer flap 3 is folded at the folding line 6 and bent outward, and then the inner flap 4 is folded at the folding line 6 and bent outward (see FIG. 2B). And in the notch formation part 10, both the folding lines 12 are pushed to an outer downward direction. Then, as shown in FIG. 3, the notch forming portion 10 is valley-folded at both fold lines 12, and the upper mountain fold line 13 and the lower mountain fold line 14 are mountain-folded. Thereby, a space 16 is formed at the corner between the inner flap 4 and the short side plate 2c that are bent outward.

  The space 16 has a substantially rectangular parallelepiped shape as shown in FIGS. 3 and 4, the lower surface is surrounded by the portion 10 a on the short side plate 2 c side of the notch forming portion 10, and the inner flap of the notch forming portion 10. The outer surface is surrounded by the four-side portion 10b, and the upper surface, the inner surface, and the front and rear surfaces are open. Further, the width becomes narrower toward the inner side and the lower side. Therefore, as shown in FIG. 4, by putting a hand through the upper opening of the space 16 and holding the handle 21 of the packed object 20 from the inner opening, the packed object 20 is gripped and the packing box 1 can be taken out.

  As described above, in the packaging box 1 according to this embodiment, after folding the outer flap 3 and the inner flap 4 to the outside, the both fold lines 12 of the notch forming portion 10 are pushed outwardly downward, thereby A space 16 is formed at the corner between the short side plate 2 and the short side plate 2 c, and the handle 21 of the packaged object 20 can be gripped through the space 16. Therefore, even when the gap between the object to be packed 20 and the packaging box 1 is narrow, a space 16 is formed in which the upper side and the outer side of the handle 21 are open, so that the handle 21 of the object to be packed 20 can be easily grasped, The package 20 can be taken out. For this reason, even when the height of the article to be packed 20 is high, it is not necessary to use a vertically divided packing box, so that the packaging material cost can be reduced.

  Further, the space 16 is formed so that the width becomes narrower toward the inner side and the lower side, and is formed so as to be guided to the handle 21 of the packaged object 20. Therefore, even when it is difficult to confirm the position of the handle 21 from the upper side with the outer flap 3 and the inner flap 4 being opened, when the hand is put into the space 16, it is naturally guided to the position of the handle 21. .

  Moreover, in the packaging box 1 which concerns on this embodiment, since the perforation etc. are not formed in the corner | angular of the inner flap 4 and the short side plate 2c, strength reduction can be prevented. Further, there is no part that is separated from the main body 2 and the inner and outer flaps 3 and 4 when unpacking. For this reason, by returning the notch forming part 10 from the posture in which the space 16 is formed (see FIG. 3) to the posture along the short side plate 2c and the inner flap 4 (see FIG. 2), the packaging box 1 is Can be reused.

  Next, with reference to FIGS. 6-7, the packaging box 1 which concerns on other embodiment of this invention is demonstrated. 6A is a perspective view showing a state in which the outer flap of the packaging box is opened and the inner flap is raised, FIG. 6B is a perspective view showing a state in which the outer flap and the inner flap of the packaging box are opened, and FIG. It is a perspective view which shows the state which opened the inner flap and outer flap of the packaging box, and formed the space.

  In the packaging box 1 according to this embodiment, the notch forming portion 10 includes a single linear cutting line 11 and a double fold extending along the folding line 6 starting from the intersection of the cutting line 11 and the folding line 6. It has a line 12 and upper and lower mountain fold lines 13, 14.

  The cutting line 11 is formed substantially at the center in the front-rear direction of the folding line 6 so as to be orthogonal to the folding line 6. The distance D1 between the upper end of the cutting line 11 and the fold line 6 and the distance D2 between the lower end of the cutting line 11 and the fold line 6 are formed equally. The distances D1 and D2 are substantially equal to the distance from the upper surface of the packaged object 20 to the handle 21.

  Both fold lines 12 are formed so as to extend from the intersection point P1 between the cutting line 11 and the fold line 6 to the point P2 that is separated from the intersection point P1 by a predetermined distance to the rear along the fold line 6. Folding and mountain folding are possible.

  As shown in FIG. 6A, the upper mountain fold line 13 is formed in a straight line between the upper end of the cutting line 11 and the point P <b> 2 on the fold line 6 in the inner flap 4. The lower mountain fold line 14 is linearly formed between the lower end of the cutting line 11 and the point P2 on the fold line 6 in the short side plate 2c.

  With such a configuration, the notch forming portion 10 has a triangular shape surrounded by one cutting line 11 and upper and lower mountain fold lines 13 and 14, and the short side plate 2 c is formed by both fold lines 12. A side portion 10a and a portion 10b on the inner flap 4 side are defined.

  A method for unpacking the packaging box 1 having the above configuration will be described. First, after folding the outer flap 3 at the folding line 6 and bending it outward, the inner flap 4 is folded at the folding line 6 and bent outward (see FIG. 6B). And in the notch formation part 10, both the folding lines 12 are pushed back rearward. Then, as shown in FIG. 7, the notch forming portion 10 is valley-folded at both fold lines 12, and the upper mountain fold line 13 and the lower mountain fold line 14 are mountain-folded. Thereby, a space 16 is formed at the corner between the inner flap 4 and the short side plate 2c that are bent outward.

  The space 16 has an inner rear surface surrounded by a portion 10a on the short side plate 2c side of the notch forming portion 10, an outer rear surface is surrounded by a portion 10b on the inner flap 4 side of the notch forming portion 10, and an upper surface. The inner surface and the front surface are open. Therefore, the object to be packed 20 can be taken out from the packing box 1 by putting a hand through the upper opening of the space 16 and grasping the handle 21 of the object to be packed 20 from the inner opening.

  As described above, also in the packaging box 1 according to the present embodiment, the space 16 in which the upper side and the outer side of the handle 21 are opened is formed even when the gap between the packaged object 20 and the packaging box 1 is narrow. The handle 21 of the package 20 can be easily gripped, and the package 20 can be taken out.

  Moreover, in the packaging box 1 which concerns on this other embodiment, since the cutting line 11 is one in the notch formation part 10, the fall of the intensity | strength of the packaging box 1 resulting from providing the cutting line 11 can be reduced. .

  Next, with reference to FIGS. 8-9, the packaging box 1 which concerns on further another embodiment of this invention is demonstrated. FIG. 8 is a perspective view showing a state in which the outer flap of the packing box is opened and the inner flap is raised, and FIG. 9 is a perspective view showing a state in which a space is formed by opening the inner flap and the outer flap of the packing box.

  In the packaging box 1 according to this embodiment, the notch forming portion 10 is folded at one straight cutting line 11 and the intersection of the cutting line 11 and the folding line 6 as shown in FIG. The front fold line 12F and the rear fold line 12R extend in the front-rear direction along the line 6, and the upper front and rear mountain fold lines 13F and 13R and the lower front and rear mountain fold lines 14F and 14R.

  The cutting line 11 is formed substantially at the center in the front-rear direction of the folding line 6 so as to be orthogonal to the folding line 6.

  The front both fold lines 12F are formed so as to extend from the intersection point of the cutting line 11 and the fold line 6 to the end point separated from the intersection point along the fold line 6 by a predetermined distance. The rear both fold lines 12R are formed so as to extend from the intersection of the cutting line 11 and the fold line 6 to the end point separated from the intersection along the fold line 6 by a predetermined distance.

  The upper front and rear mountain fold lines 13F and 13R are linearly formed in the inner flap 4 between the upper end of the cutting line 11 and the end points of the front and rear fold lines 12F and 12R. Lower front and rear mountain fold lines 14F and 14R are formed in a straight line between the lower end of the cutting line 11 and the end points of both front and rear fold lines 12F and 12R in the short side plate 2c.

  With such a configuration, the notch forming portion 10 has a rhombus shape surrounded by the upper front and rear mountain fold lines 13F and 13R and the lower front and rear mountain fold lines 14F and 14R.

  In the packaging box 1 having the above-described configuration, after the outer flap 3 and the inner flap 3 are bent outward, the notch forming portion 10 pushes the portion of the cutting line 11 outward. Then, as shown in FIG. 9, the notch forming portion 10 is valley-folded by the front and rear fold lines 12F and 12R, and the upper front and rear mountain fold lines 13F and 13R and the lower mountain fold line 14F, 14R is folded in a mountain. Thereby, a space 16 is formed at the corner between the inner flap 4 and the short side plate 2c that are bent outward.

  The space 16 is a portion in front of the cutting line 11 of the notch forming portion 10 and the front surface is surrounded, and a portion of the notch forming portion 10 in the rear of the cutting line 11 is surrounded by the rear surface. The upper surface, the inner surface, and the outer surface are open. Therefore, the object to be packed 20 can be taken out from the packing box 1 by putting a hand through the upper opening of the space 16 and grasping the handle 21 of the object to be packed 20 from the inner opening.

  Also in the packaging box 1 according to this embodiment, the volume of the space 16 can be formed relatively large while reducing the strength reduction of the packaging box 1 with one cutting line 11 in the notch forming portion 10. It becomes easier to grip the article 20 to be packed.

  In the embodiment of the present invention, the shape, size, and position of the notch forming portion 10 are appropriately changed so as to correspond to the position and size of the handle 21 or to correspond to the shape of the packaged object 20. Can do. Moreover, in embodiment of this invention, although the case where the handle 21 was formed in the to-be-packaged object 20 was demonstrated, the to-be-packaged object 20 in which the handle 21 is not formed, and the some to-be-packaged object 20 are packed. It can also be applied to cases.

  Furthermore, since the above description of the embodiment of the present invention describes a preferred embodiment of the packaging box according to the present invention, there may be various technically preferable limitations. The technical scope of the invention is not limited to these embodiments unless specifically described to limit the present invention. That is, the above-described components in the embodiment of the present invention can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible.
