Locking portions 23b provided at both ends of the grip portion 23a are integrally formed of synthetic resin.
The b is inserted and locked in the locking hole 25 so as to be detachably attached.

The handle 2 attached to the side holding portion 36
Reference numeral 3 protrudes outside from an opening 22 formed in the third side wall 3c. Thereby, the packing box 1 can be carried by the handle 23.

It should be noted that the handle 23 may be formed by packing the object to be packed 31 and then engaging the engaging portion 23b with the engaging hole 25 exposed at the opening 22 to attach it. When the holding buffer member 33 is covered on the upper surface side of the article to be packed 31, the upper surface side of the holding buffer member 33 is
Accessories 37 such as manuals and accessories as shown in
Is placed. By placing the small articles 37, the upper surface of the article to be packed 31 is placed on the upper lids 5a to 5a through the small articles 37.
By d, the whole is pressed and held.

When the holding buffer member 33 is pressed against the upper surface of the article 31 to be packed, the first step portion 14 and the second step portion 15 are pressed.
And a load will be applied. However, the shape of the first step 14 is maintained by the second tongue piece 17a, and the shape of the second step 15 is maintained by the support piece 19. The steps 14 and 15 are not damaged.

As described above, when the holding buffer member 33 is placed on the article to be packed 31, the second and fourth upper lids 5b,
After bending 5d, the third upper lid 5c is bent,
Next, the first upper lid 5a is bent, and the locking piece 5e is inserted and locked into an engagement hole 5f formed in the base end of the third upper lid 5c.

If necessary, the tip of the first upper lid 5a and the upper end of the third side wall 3c where the tip abuts against each other are adhered to each other with an adhesive tape (not shown), so as to be covered. The packaging box 1 in which the packaging material 31 is stored and held can be closed so that it cannot be opened.

After the handle 23 is placed on the article to be packed 31 with the holding buffer member 33, the third side wall 3
The locking portion 23b is inserted and locked into the pair of locking holes 25 of the side surface pressing portion 36 exposed at the opening 22 of FIG.

According to the packing device having such a configuration, the handle 23 for carrying the packing box 1 is held by the holding buffer member 33.
The opening 22 formed in the third side wall 3c of the packing box 1 is attached to the locking hole 25 formed in the side pressing portion 36 of the packing box 1.
From the outside. That is, the handle 23 for carrying the packing box 1 is not provided directly on the packing box 1, but is provided on the holding buffer member 33 for holding the article 31 in the packing box 1.

Therefore, when carrying the packing box 1 with the handle 23, the weight of the object to be packed 31 is such that the outer side surface of the side holding portion 36 in which the pair of locking holes 25 is formed is entirely covered by the packing box 1. The third side wall 3c is received in contact with the inner surface. That is, the weight of the packaged object 31 is dispersed throughout the third side wall 3c.

As a result, unlike the case where the handle 23 is provided directly on the third side wall 3c of the packing box 1, only a part of the side wall 3c does not receive the weight of the article 31 to be packed. It is possible to prevent the side wall portion 3c from being easily damaged by the weight of the packaged object 31.

Further, since the handle 23 is provided using the holding buffer member 33 for holding the packaged object 31, there is no need for a dedicated member for providing the handle 23, which is economical. In addition, the configuration does not become complicated.

The handle 23 is formed with a locking portion 23b, and the locking portion 23b is inserted and locked into a pair of locking holes 25 of the side surface pressing portion 36 and attached. Therefore, the handle 23 is detachable from the locking hole 25 and can be attached only when necessary. For example, in a case where the packing boxes 1 are stacked and arranged in a warehouse or the like, the handle 23 is removed. With this arrangement, it is possible to prevent the packing boxes 1 from being arranged without any gaps, and to prevent the packing boxes 1 from being caught by the handle 23 and breaking the loaded state.

When the handle 23 is not provided in the packing box 1, the one side holding portion 36 in which the locking hole 25 of the holding buffer member 33 is formed is replaced with the second side holding portion 36 in which the opening 22 of the packing box 1 is not formed. 1 side wall portion 3a, and the other side surface pressing portion 36 on which the locking hole 25 is not formed is connected to the third side wall portion 3a.
It is provided so as to be located on the c side.

As a result, the opening 22 is closed by the outer side surface of the side pressing portion 36, and the locking hole 25 is not exposed to the outside from the opening 22, so that the appearance is good. Alternatively, it is possible to prevent foreign matter and dust from entering the packing box 1 through the opening 22 and the locking hole 25.

A plate-like member 2 for forming the packing box 1
The bent portion 13 for holding the packaged object 31 is integrally formed, and the bent portion 13 is bent stepwise so that the packaged object 31 can be held on the first step portion 14. .

Therefore, the first step portion 14 can be used as a buffer member for supporting the lower surface side of the article 31 to be packed, so that the first step portion 14 can be used as compared with the case where a buffer member made of a member different from the packing box 1 is used. Not only can the number of parts be reduced,
Since the labor of parts management and the like can be omitted, the packing work is also facilitated.

The bent portion 13 has not only the first step portion 14 but also a second step portion 15. The second step portion 15 has a holding buffer for holding the upper surface side of the article 31 to be packed. Member 33
Can be engaged and held.

Therefore, the bent portion 13 bent stepwise can be used not only for holding the article to be packed 31 but also for holding the buffer member 33 for holding down, thereby reducing the number of parts. it can.

Further, the first step portion 14 of the bent portion 13 is held by the second tongue piece 17a so as not to lose its shape, and the second step portion 15 is held by the support piece 19 so as not to lose its shape. Is held in.

Therefore, the first and second step portions 14 and 15
In the configuration, even if the bent portion 13 is simply bent in a stepped manner, the stepped shape is not damaged by the load applied from the upper surface side. That is, since the bent portion 13 bent in a stepped manner has a predetermined strength without being reinforced by using a reinforcing member or the like, the number of parts can be reduced also by that.

In the above embodiment, the opening 22 is formed only in the third side wall 3c of the packing box 1. However, the opening 22 is also formed in the first side wall 3a, and the holding buffer member 33 is provided. The locking holes 25 for providing the handles 23 may be formed in the pair of side surface pressing portions 36.

The opening formed in the packing box 1 is shown in FIG.
As shown in the figure, the size of the locking portion 23b of the handle 23, that is, the opening area is sufficiently smaller than the opening portion 22 of the above-described embodiment, and the locking hole 25 formed in the side pressing portion 36 is formed. It may be formed by two through-holes 22a having substantially the same size as the above.

As a result, a decrease in the strength of the side wall portion where the through hole 22a of the packing box 1 is formed can be reduced, so that when the packing boxes 1 are stacked, not only is the lower packing box 1 hard to be crushed, but also the side walls are hardly crushed. If you want to print on the outside of a copy,
In some cases, the missing portion of the print information can be reduced.

The opening formed in the side wall 3c of the packing box 1 may be a substantially inverted U-shaped groove-like opening 22b as shown in FIG. 6 (a). Not only can the area be reduced, but even if the handle 23 is previously fixed to the side holding portion 36, the handle 23 can be removed from the groove-shaped opening 22b as shown by the arrow in FIG. 1 can be projected outside.

FIGS. 7 and 8 show another embodiment of the packing box 1 according to the present invention. In this embodiment, the handle 23 is directly attached to the packing box 1. That is, FIG. 7 is an exploded view of the plate-like member 2. The pair of second paste margins 20 are attached to the plate-like member 2, and the second and fourth glue margins 20 are bonded and fixed to the plate-like member 2. A pair of band-shaped locking holes 27 into which the locking portions 23b of the handle 23 can be inserted are respectively formed in the side wall portions 3b and 3d.

As shown in FIG. 8, the second glue margin 20 and the locking holes 27 formed in the side walls 3b and 3d are used to bond and fix the second glue margin 20 to the side walls 3b and 3d, respectively. It is formed so as to be in a communication state when it is turned on. The handle 23 can be detachably attached to the pair of locking holes 27 by inserting and locking the locking portion 23b.

In this embodiment, FIGS.
The same reference numerals are given to the same parts as in the embodiment shown in FIG. According to such a configuration, the second glue margin portion 20 and the side wall portions 3b and 3d are joined and fixed to form a double structure (
Since the handle 23 is attached to the portion where the two pieces of corrugated cardboard are stacked), the attachment portion of the handle 23 is not easily damaged.

In addition, the side walls 3b and 3d are
1 and a second buffer portion 20 of the bent portion 13 provided for holding the holding buffer member 33,
Because there is no need to use a dedicated reinforcing member for that reinforcement,
There is no increase in cost or complication of the configuration due to an increase in the number of parts.

In this embodiment, a pair of locking holes 27 are formed in both the pair of bent portions 13 and the second and fourth side walls 3b and 3d.
