Description

  The present invention relates to a packaging box, and more particularly, to a packaging box in which handle holes are formed on opposing side walls.

  As shown in FIG. 6, many of the conventional packaging boxes 1 ′ are formed with a pair of long hole-shaped handle holes 6 in the substantially central portions of the opposing side walls 11 b and 11 d. The packaging box 1 'was lifted and carried. However, if the weight of the packing box after packing is light, in the case of a packing box of a size that can be carried by a person of about 10 kg, and trying to lift such a packing box, FIG. As shown in Fig. 2, the body was bent into a "<" shape and both hands were lowered in the vertical direction, so that the packaging box 1 'was lifted, which caused a heavy burden on the muscles of the hips and wrists including the back muscles. . And if the burden was too great, there was a case of so-called tight waists.

However, as far as the applicants have examined applications related to packaging boxes, proposals from the viewpoint of facilitating provision with one hand have been made so far (for example, Patent Document 1), but a packaging box with a certain amount of weight can be held with both hands. There was no proposal from the viewpoint of making it easier to hold.
JP 2000-351166 A

  The present invention has been made in view of such problems, and its object is to provide a packaging box that is easy to hold with both hands and does not place a heavy burden on the waist even when lifting a heavy packaging box. is there.

  It is another object of the present invention to provide a packaging box that can be easily lifted and carried by a plurality of people and can be lifted from any direction.

  A further object of the present invention is to prevent foreign matter from entering the packing box from the handle hole.

  According to the present invention, there is a packaging box in which two sets of handle holes are formed on opposite side walls, wherein the handle holes are long holes inclined with respect to the horizontal direction, and are substantially parallel to the width direction of the side walls. Provided is a packaging box characterized in that it is formed symmetrically about the center.

  Here, from the viewpoint of making it easier to hold with both hands, the shape of the handle hole is preferably a shape inclined upward toward the approximate center in the width direction of the side wall.

  Further, from the viewpoint of suppressing foreign matter from entering the packing box from the handle hole, the handle hole is formed by bending a bent piece in which at least a part of the outer periphery is formed by a cut or perforation. preferable.

  In the packing box of the present invention, since the two sets of handle holes are each a long hole inclined with respect to the horizontal direction, the body can be lifted by holding it with both hands without bending it into a "<" shape. Become. Thereby, a big burden is not applied to the waist and the wrist. In addition, since the handle hole is formed symmetrically about the substantially center in the width direction of the side wall, it can be held from either side when lifted by one person, and can also be held by two persons.

  Further, when the shape of the handle hole is inclined upward substantially toward the center in the width direction of the side wall, it becomes easier to hold the packaging box with both hands.

  Furthermore, if the handle hole is formed by bending a bent piece with at least a part of the outer periphery formed by a cut or perforation, the handle hole is sealed with the bent piece when the handle hole is unused. It is possible to prevent foreign matter from entering the packaging box from the outside. Further, the handle hole can be easily formed by bending the bent piece when necessary.

  Hereinafter, although the packaging box concerning the present invention is explained based on a figure, the present invention is not limited to these embodiments at all.

  FIG. 1 is a perspective view showing an embodiment of a packaging box according to the present invention, and FIG. 2 is a development view of the packaging box 1 of FIG. As shown in FIG. 2, the packaging box 1 of this figure has four side walls 11a, 11b, 11c, and 11d formed continuously via folding lines 71a, 71b, and 71c. And the margin piece 10 is formed in the side of the side wall 11a via the bending line 71d. Further, upper flaps 12a, 12b, 12c, and 12d are connected to the upper end edges of the side walls 11a, 11b, 11c, and 11d via folding lines 72a, 72b, 72c, and 72d, respectively, and each side wall 11a, 11b, Lower flaps 13a, 13b, 13c, and 13d are connected to lower end edges of 11c and 11d via folding lines 73a, 73b, 73c, and 73d, respectively. Note that the lengths of the upper and lower sides of the upper flaps 12a and 12c and the lower flaps 13a and 13c from the side walls 11a and 11c are substantially half of the lateral width L (shown in FIG. 3) of the side walls 11b and 11d.

  On the side walls 11b and 11d that face each other when assembled, the bent pieces 2a and 2b and the bent pieces 3a and 3b are formed integrally with the side walls 11b and 11d. FIG. 3 shows a specific configuration of these bent pieces. Since the bent pieces 2a and 2b and the bent pieces 3a and 3b have the same shape, the bent pieces 2a and 2b will be described as a representative. As shown in FIG. 3, the combined shape of the bent pieces 2 a and 2 b is an inverted heart shape, and the center of the inverted heart shape on the left and right is exactly coincident with the center of the side wall 11 b in the width direction. In other words, the bent pieces 2a and 2b are symmetrical with respect to the center in the width direction of the side wall 11b. The bent pieces 2a and 2b have an inclination angle θ with respect to the horizontal direction. The inclination angle θ is not particularly limited, and may be appropriately determined from the weight of the article to be stored, the size of the packing box, and the like, but is generally in the range of 30 ° to 60 °.

  The upper sides of the bent pieces 2a and 2b are formed by fold lines 21a and 21b, and the other outer circumferences of the bent pieces 2a and 2b are formed by perforations 20, 22a and 22b. Of course, the folding lines 21a and 21b may be replaced by perforations, or the perforations 20, 22a and 22b may be replaced by notches, and all the outer circumferences of the bent pieces 2a and 2b may be perforated. What is necessary is just to determine suitably the processing state of the outer periphery of bending piece 2a, 2b from the material etc. of a packaging box.

  In assembling the packaging box 1 having such a configuration, first, the glue piece 10 is fixed to the side of the side wall 11d to form a three-dimensional shape. The opposed lower flaps 13b and 13d are bent inward substantially perpendicular to the side walls 11b and 11d. Next, the lower flaps 13a and 13c are folded inward substantially perpendicular to the side walls 11a and 11c so as to overlap the lower flaps 13b and 13d. At this time, as described above, the length of the lower sides of the lower flaps 13a and 13c from the side walls 11a and 11c is substantially half the lateral width of the side walls 11b and 11d, so that the lower flaps 13a and 13c are inward. When bent, the lower sides of the lower flaps 13a and 13c come into contact with each other. And an adhesive tape is affixed so that the contact part of lower flap 13a, 13c may be covered, and the bottom wall of a packaging box is formed. Of course, the lower flaps 13a and 13c may be joined using staples or the like. The state in which the bottom wall of the packaging box is thus formed is the perspective view of FIG.

  In the state shown in FIG. 1, when an article to be packed is accommodated in the packing box, the upper flaps 12b and 12d are bent inward substantially perpendicularly to the side walls 11b and 11d, and then the upper flap 12b and The upper flaps 12a and 12c are folded inward substantially perpendicular to the side walls 11a and 11c so as to overlap with 12d. At this time, as described above, the lengths of the upper sides of the upper flaps 12a and 12c from the side walls 11a and 11c are substantially half of the lateral width of the side walls 11b and 11d, so that the upper flaps 12a and 12c are inward. When bent, the upper sides touch each other. And an adhesive tape is affixed so that the contact part of upper flap 12a, 12c may be covered, and a series of packing processes are completed.

  When holding and carrying the packing box that has been packed with both hands, bend one of the two opposing folding pieces 2a, 2b, 3a, 3b formed on the opposing side walls 11b, 11d, respectively. A handle hole is formed, a finger is inserted into the handle hole, and the packing box is lifted and carried. Specifically, as shown in FIG. 4, an external force is applied from the outside to the inside on the bent piece 3b blocking the required handle hole 5b. Since the outer periphery of the bending piece 3b is formed by the perforation 32b and the bending line 31b, the perforation 32b is broken by the applied external force to form a continuous cut, and the bending piece 3b is packed with the bending line 31b as a boundary. Folded into a box. As a result, the handle hole 5b is formed. At this time, the other bent piece 3a is still integrated with the side wall.

  In addition, when punching and forming a packaging box in an unfolded state from a raw material plate such as cardboard, it is of course possible to punch and form the handle hole at the same time. There is a risk. In this regard, when the handle hole 5b is required as in the above-described configuration, if the bent piece 3b is bent to form the handle hole 5b, foreign matter can be mixed into the packaging box from the handle hole 5b. This is desirable because it can be prevented.

  FIG. 5 is a perspective view showing another embodiment of the packaging box according to the present invention. The packaging box of FIG. 5 is different from the packaging box of the above-described embodiment in that the handle holes 4a and 4b are formed apart from each other. That is, the handle holes 4a and 4b are formed at positions that are symmetrically separated from each other about the center in the width direction of the side wall 11b. If the handle holes 4a and 4b are formed so as to be separated from each other in this manner, the packaging box can be lifted and carried in the form of two people facing each other, which is particularly useful when the packaging box cannot be held alone. . What is necessary is just to determine the space | interval of the handle holes 4a and 4b suitably from the material of a packaging box, the weight of a to-be-packaged object, etc.

  Although the folded piece is not shown in the packaging box of FIG. 5, it is preferable that the handle hole is formed by bending the folded piece from the viewpoint of preventing foreign matter from being mixed, as in the above-described embodiment.

  In the embodiment described above, two sets of handle holes are provided on a pair of opposing side walls, but it is needless to say that two sets of handle holes may be provided on each of two opposing side walls. Moreover, the packaging box of this invention is not limited to a thing with four side walls, You may have many more side walls.
