Description

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

  When transporting or storing an image forming apparatus such as a printer or a multifunction peripheral, or parts constituting the image forming apparatus, an A-type packaging box formed of a packaging material such as cardboard is often used. . The A-type packing box is a box having a shape in which the opening of the box-shaped main body is opened and closed by a folding inner and outer flap, and is widely used because it is relatively inexpensive.

  Such a packaging box is formed by bending a pair of inner flaps inward and then bending the pair of outer flaps so as to overlap the upper side of the pair of inner flaps. It is sealed by applying an adhesive tape along the edge. At this time, the adhesive tape is preferably attached so that the center in the width direction is along the leading edge of the pair of outer flaps that are abutted. However, since this operation is generally performed manually, the operator visually adjusts the center of the adhesive tape in the width direction to the abutted leading edge.

  Then, as shown in FIG. 4 (A), the center in the width direction of the adhesive tape 102 is shifted in the front-rear direction from the leading edge 101a against which the pair of inner flaps 101 are abutted, or in FIG. 4 (B). As shown in the drawing, the adhesive tape may be stuck with the tip edges 101a of the pair of outer flaps 101 being shifted in the left-right direction. Or the adhesive tape 102 may be affixed in the direction which cross | intersects the front-end | tip edge 101a with which the pair of inner flaps 101 were abutted. As described above, when the adhesive tape 102 is pasted from the regular position, there is a problem that the appearance of the packaging box 100 is deteriorated.

  Therefore, conventionally, as in Patent Document 1, a thin portion is formed by compressing a range wider than the width of the adhesive tape along the leading edge of the abutted outer flap, and the adhesive portion is adhered along the thin portion. There has been proposed a packaging box configured to suppress swelling of the central portion of the packaging box due to the thickness of the adhesive tape by applying the tape.

JP 2001-72043 A

  In the packaging box disclosed in Patent Document 1, a thin-walled portion indicating the sticking position of the adhesive tape is formed along the front edge of the outer flap, but the thin-walled portion absorbs the thickness of the adhesive tape. It is intended, and is not intended to indicate the normal position of the adhesive tape. In other words, a convex part is provided on the transport drum for performing flexographic printing on the packing box, and the leading edge of the outer flap is compressed by this convex part to form a thin-walled part. There is no positioning. Therefore, there is a possibility that the thin portion may be formed to be shifted in the front-rear direction or the left-right direction from the leading edge of the outer flap, so that the thin portion follows the center of the adhesive tape to the leading edge of the abutted outer flap. It cannot be a guide.

  In view of the above circumstances, the present invention provides a packaging box that can be sealed with a good appearance with an adhesive tape by guiding the leading edge of the abutted outer flap along the center in the width direction of the adhesive tape. With the goal.

  In order to achieve the above object, a packaging box according to the present invention includes a rectangular tubular body, a pair of inner flaps connected to one opposing edge of the body and bent inward, and the body of the body. A pair of outer flaps connected to the other opposing end edge, bent inwardly and stacked on the upper side of the pair of inner flaps, and the tip edges of the pair of outer flaps abut against each other A packaging box sealed by sticking an adhesive tape along the tip edge, wherein the pair of outer flaps are respectively attached to both side edges orthogonal to the tip edge from the tip edge to the adhesive. The mark part which shows the position of the half length of the width | variety of a tape is provided.

  By adopting such a configuration, the adhesive tape is attached at the center in the width direction by abutting the end edges of the pair of outer flaps to each other and sticking both side edges of the adhesive tape along the mark portions. Affixing can be performed along the abutted leading edge, and the packaging box can be nicely sealed with an adhesive tape.

  In this invention, the said mark part is a notch part formed in the corner | angular of each of the said front-end edge and each said both-sides edge of a pair of said outer flap, The length of the direction along the said side edge of this notch part The thickness may be equal to half the width of the adhesive tape.

  By adopting such a configuration, the deviation of the pair of outer flaps can be made inconspicuous. Moreover, since the side edge of an adhesive tape is latched by the side surface of a notch part, the shift | offset | difference of a pair of outer flap can be controlled.

  According to the present invention, since the center of the adhesive tape in the width direction can be attached to the leading edge of the abutted outer flap, the packaging box can be nicely sealed with the adhesive tape.

It is a perspective view which shows the state which a pair of outer flap shifted | deviated to the left-right direction.

  Hereinafter, a packaging box according to an embodiment of the present invention will be described with reference to the drawings.

  A packaging box according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a packaging box, FIG. 2 is a development view of the packaging box, and FIG. 3 is a perspective view showing a state in which an adhesive tape is attached to a notch portion in the packaging box. 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.

  The packaging box 1 has a square cylindrical body 2, a pair of upper and lower inner flaps 3A and 3B, and a pair of upper and lower outer flaps 4A and 4B. The packaging box 1 is made of a high-strength packaging material such as cardboard.

  The trunk | drum 2 has a pair of short side plate 2a which opposes, and a pair of long side plate 2b which opposes. As shown in FIG. 2, the pair of short side plates 2 a and the pair of long side plates 2 b are alternately connected via fold lines, and are bent at right angles along the fold lines so that a rectangular tube is obtained. A cylindrical body 2 is formed. Square openings are respectively formed at the upper and lower ends of the body 2.

  The pair of upper inner flaps 3 </ b> A are connected to the upper edges of the pair of short side plates 2 a of the body portion 2 so as to be foldable inward via a fold line. The pair of lower inner flaps 3 </ b> B are connected to the lower edges of the pair of short side plates 2 a of the body portion 2 so as to be bent inward via a fold line.

  The pair of upper outer flaps 4 </ b> A are connected to the upper edges of the pair of long side plates 2 b of the body portion 2 so as to be bent inward via a fold line. The pair of upper outer flaps 4A are folded outside the pair of upper inner flaps 3A, the leading edge 10 of each upper outer flap 4A is abutted against each other, and the adhesive tape 5 is applied along the abutting leading edge 10 By this, the upper side opening of the trunk | drum 2 is closed.

  The pair of lower outer flaps 4B are connected to the lower edges of the pair of long side plates 2b of the body 2 so as to be foldable inward via a fold line. The pair of lower outer flaps 4B are folded outside the pair of lower inner flaps 3B, the leading edges 10 of the respective lower outer flaps 4B are abutted against each other, and the adhesive tape ( By sticking (not shown), the lower opening of the trunk 2 is closed. Thereby, the packaging box 1 is sealed.

  Cutouts 7 are formed at the corners of the leading edge 10 and the side edges 11 in each of the pair of upper outer flaps 4A and each of the pair of lower outer flaps 4B.

  As shown in FIGS. 2 and 3, the notch 7 has a rectangular shape that is long in the direction of the side edge 11 of each outer flap 4A, 4B, and extends along the side edge 11 of each outer flap 4A, 4B. The length L1 is the same as the half of the width of the adhesive tape 5 or slightly longer than the half of the width of the adhesive tape 5, and is along the leading edge 10 of each outer flap 4A, 4B. The length L2 is about the thickness of the outer flaps 4A and 4B. However, the length L <b> 2 along the tip edge 10 may be such that the cutout portion 7 can be confirmed. As the adhesive tape 5, the adhesive tape used for sealing of a general packaging box can be used.

  A method for sealing the packaging box 1 having the above configuration will be described. First, the pair of upper inner flaps 3A are folded inward via a fold line, and then the pair of upper outer flaps 4A are folded inward via a fold line and overlapped on the outside of the pair of upper inner flaps 3A. And the front-end edge 10 of each upper side outer flap 4A is mutually abutted. At this time, as shown in FIG. 3, the pair of upper outer flaps 4 </ b> A are positioned so that the respective notches 7 are arranged in a straight line along the side edges 11 of the outer flaps 4 </ b> A. Thereby, the notch part 7 which opposes forms the recessed part 8 of the width | variety comparable as the width | variety of the adhesive tape 5 along the left-right side edge 11 of a pair of upper outer flap 4A. The tip edge 10 against which the pair of upper outer flaps 4 </ b> A are abutted becomes the center of the recess 8.

  And the adhesive tape 5 is stuck between the recessed parts 8 of the left and right side edges 11 of the packaging box 1. At this time, by sticking the adhesive tape 5 so as to fit into both the concave portions 8, the center in the width direction of the adhesive tape 5 is along the abutted leading edge 10. Thereby, the upper side opening of the trunk | drum 2 of the packaging box 1 is closed.

  Next, the pair of lower inner flaps 3B and the pair of lower outer flaps 4B are similarly bent, and the lower opening of the packaging box 1 is closed with an adhesive tape. Thereby, the packaging box 1 is sealed.

  As described above, in the packaging box 1 according to the present embodiment, if the adhesive tape 5 is attached along the concave portion 8 having a width approximately equal to the width of the adhesive tape 5, the center in the width direction of the adhesive tape 5 is a pair. The outer end flaps 4A and 4B of the outer side flaps 4A and 4B come into contact with the abutted tip edge 10. Further, the pair of outer flaps 4A and 4B can be positioned so that the pair of outer flaps 4A and 4B are not displaced in the width direction by arranging the notches 7 along the side edges 11 in a straight line.

  Accordingly, the sticking position of the adhesive tape 5 is shifted in the width direction of the adhesive tape 5 from the tip edge 10 against which the pair of outer flaps 4A, 4B are abutted, or the tip edge 10 of each of the pair of outer flaps 4A, 4B. However, without sticking the adhesive tape 5 in a state shifted in the width direction, the adhesive tape 5 can be applied with good appearance.

  Further, as shown in FIG. 3, even if the front edge 10 of each of the pair of outer flaps 4 </ b> A and 4 </ b> B is slightly displaced in the width direction, each outer flap 4 </ b> A has an end surface 7 a side of the notch 7. Since the corner C <b> 1 with the edge 11 is separated via the notch 5, the shift becomes inconspicuous. Note that the shift in the position of the corner C <b> 2 between the side surface 7 b of the notch 7 and the tip edge 10 is hidden by the adhesive tape 5.

  Furthermore, since the side edge of the adhesive tape 5 is locked to the end surface 7a of the notch 7, the pair of outer flaps 4A and 4B can be prevented from being displaced by an external force.

  In the present embodiment, the cutout portion 7 has a rectangular shape, but the length L1 of the cutout portion 7 along the side edges 11 of the pair of outer flaps 4A and 4B is half the width of the adhesive tape 5. Other shapes may be used as long as the width is sufficient. For example, it is good also as a triangular shape which cut off the angle | corner of each front edge 10 and the side edge 11 of a pair of outer flap 4A, 4B diagonally, or a fan-shaped shape which cut off the corner | angular shape. In addition, a line or the like serving as a mark is printed on the side edges 11 of the pair of outer flaps 4A and 4B, not the notches, at positions separated from the front edge 10 by half the width of the adhesive tape 4. May be.

  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. The description of the embodiment of the present invention described above does not limit the contents of the invention described in the claims.
