[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a base sheet and an outer box constituting a packaging box according to the present invention. FIG. 2 is an enlarged view of a part thereof.
In the figure, reference numeral 10 denotes a base sheet, and reference numeral 20 denotes an outer box.
[0018]
First, the base sheet 10 includes a rectangular flat portion 11 on which an article to be packaged is placed, and flaps 12 provided on a pair of opposed side edges 11a of the peripheral edge of the flat portion 11. Each of the flaps 12 is formed in a horizontally long rectangular shape along the side edge 11a, and is provided so as to rise from the plane portion 11 at a right angle. From both side edges of each flap 12, elongated insertion portions 13 are respectively provided extending in opposite directions in parallel along the side edges 11a of the plane portion 11, respectively.
[0019]
As shown in FIG. 2, each insertion portion 13 is constituted by a band-shaped body portion 14 extending straight and a trapezoidal tip portion 15. The body 14 is provided with bending lines m and n at the base end position and the middle position in the length direction, and cuts off both sides of the middle position in the length direction in a semicircle to form a finger hook 14a there. On the other hand, the distal end portion 15 has a short side 15a of a pair of parallel trapezoidal sides as a distal side, a long side 15b as a proximal side, and lengths a and b, respectively.
[0020]
Note that the bending lines mn are formed by thinning or perforating along the lines.
[0021]
Next, the outer box 20 has a cubic shape whose bottom is opened, and insertion holes 22 are formed near the lower corners of the opposing side surfaces 21, respectively. As shown in FIG. 2, each insertion hole 22 has a length (height) c. And
a <c <b
So that the relationship is
[0022]
That is, the length a of the short side 15a of the trapezoidal tip 15 is made smaller than the length c of the insertion hole 22, while the length b of the long side 15b is made larger than the length c of the insertion hole 22. Note that if the width of the body 14 is d, d <c.
[0023]
Now, when a product such as a copying machine is packaged as an article to be packaged using this packaging box, the product is placed on the base sheet 10 and the outer box 20 is covered from above so as to cover the product. Each flap 12 is applied to the outside of the opposing side surface 21 of the outer box 20. Then, the distal end portion 15 of the insertion portion 13 is inserted into the insertion hole 22, and the long side 15 b of the distal end portion 15 is forcibly pushed into the insertion hole 22, and as shown in FIG. Hang both ends of the to prevent it from falling out.
[0024]
At this time, since the length a of the short side 15a of the trapezoidal tip 15 is smaller than the length c of the corresponding insertion hole 22, the tip 15 of the insertion portion 13 is easily inserted into the insertion hole 22. be able to. In addition, since the length b of the long side 15b is made larger than the length c of the insertion hole 22, once inserted, both ends of the long side 15b are hooked on the edge of the hole, and the tip end 15 of the insertion portion 13 is inserted from the insertion hole 22. It can be prevented from coming off easily.
[0025]
When unpacking the packaging box and taking out the product, put a finger on the finger hook 14a of the insertion portion 13 and pull in the direction indicated by the arrow A in FIG. Then, as shown in FIG. 4B, the insertion portion 13 is bent at the bending lines mn to release the long side 15 b of the distal end portion 15 from being hooked, and the distal end portion 15 of the insertion portion 13 is pulled out from the insertion hole 22. Thereafter, the outer box 20 is lifted to remove the cover.
[0026]
In addition, the shape and the number of the flap 12, the insertion portion 13, and the insertion hole 22 are not limited to the examples described above, and can be appropriately changed.
[0027]
【The invention's effect】
As described above, according to the present invention, when packaging an object to be packaged, the object to be packaged is placed on the base sheet and covered with the outer box, and the insertion portion provided on the flap is inserted into the insertion hole of the outer box. In this case, even an inexperienced person can easily perform the packaging operation. In addition, since a separate fastening member is not required, it is possible to reduce the cost without adding extra parts, and it is not necessary to use a plastic material or the like.
[0028]
According to the second aspect of the present invention, since the insertion portion extends in the parallel direction along the periphery of the flat portion, the direction in which the insertion portion provided on the flap is inserted into the insertion hole of the outer case is set so that the outer case is separated from the base sheet. Direction, so that even when a force in the direction of separating the outer box is applied, the insertion part does not easily come out of the insertion hole even when a force is applied, and the connection between the base sheet and the outer box is ensured. it can.
[0029]
According to the third aspect of the present invention, the tip of the insertion portion has a trapezoidal shape, and the shorter side of the pair of parallel sides of the trapezoidal shape is the tip side, so that the tip of the insertion portion can be easily inserted into the insertion hole. On the other hand, since the long side is set as the base end side, once inserted, the long side is hooked, so that the insertion portion can be prevented from easily coming out of the insertion hole.
[0030]
According to the invention according to claim 4, since the length of the short side of the trapezoidal shape is smaller than the length of the insertion hole, the tip of the insertion portion is easily inserted by the insertion hole, while the length of the long side is reduced by the insertion hole. Since the length is longer than the length of the insertion portion, the insertion portion can be more easily prevented from coming out of the insertion hole by being hooked after the insertion.
[0031]
According to the fifth aspect of the present invention, since the insertion portion is provided with the folding line, the tip of the insertion portion can be easily pulled out from the insertion hole by bending at the folding line, and the workability when unpacking is improved. Can be.
[0032]
According to the invention according to claim 6, since the finger hook portion is formed in the insertion portion, the tip of the insertion portion can be easily pulled out from the insertion hole by putting a finger on the finger hook portion, and the workability when unpacking the package. Can be increased.
