[Prior Art] As a box with a handle hole, which has been already proposed, the one disclosed in Japanese Utility Model Publication No. 56-49866 is known. The box with a handle hole disclosed in this publication is shown in FIGS.
As shown in the figure, at the time of manufacturing, the fastening portion 2 at the tip of the inner lid wall 1 is folded back inward along a folding curve 3, and the fastening portion 2 is attached so as to be aligned with the upper end portion of the handle hole 4, and the handle hole 4 The upper edge of the surrounding area is reinforced.

[Problems to be solved by the invention] However, in the conventional box with a handle hole, as shown in FIG. 6, when the box 5 is lifted in the direction of arrow A by placing the hand 5 on the upper end of the handle hole 4, reinforcement is provided. Although the effect is obtained, as shown in FIG. 7, the hand 5 may be hung on the lower end of the handle hole 4 to move the box 6 in the direction indicated by the arrow B. In this case, the handle hole 4
Since the periphery of the lower end of the handle is not reinforced, the periphery of the handle hole 4 may be broken.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a box with a handle hole configured to reinforce the entire periphery of the handle hole.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is a box with a handle hole having a handle hole in an opposing side wall, which is continuously provided to the upper end side of the opposing side wall through a folding curve. And an inner lid wall, and a fastening portion connected to the inner lid wall via a fold curve and a slit. When the fastening portion is folded back inside the facing side wall, A hole is provided at a position corresponding to the handle hole, and the upper and lower sides of the handle hole of the fastening portion and the opposing side wall are stuck and fixed.

[Operation] As described above, in the present invention, when the fastening portion is folded back to the inside of the opposite side wall, the fastening portion reaches below the handle hole. Reinforced. Therefore, even if the lower side of the handle hole is reached and the box is moved laterally, the periphery of the handle hole is not damaged.

[Embodiment] The present invention will be described in detail below with reference to an embodiment shown in the drawings.

FIG. 1 is a developed plan view showing an embodiment of a box with a handle hole according to the present invention. The box with a handle is a box made of cardboard or the like, and has a sticking portion 11 provided on the left side of the first side wall 10 and vertical folding curves 12 to 14 on the right side of the first side wall 10. The second to fourth side walls 15 to 17 are sequentially connected to each other via the. Further, at the time of assembly, the first side wall 10 and the third side wall 16 face each other, and the second side wall 15 and the fourth side wall 17 face each other. The second side wall 15 and the fourth side wall 17 face each other.
Handle holes 18 and 19 are provided at the upper positions of the side walls 17 of the respective ones so as to correspond to each other.

Further, at the lower portions of the first to fourth side walls 10 and 15 to 17, the first to fourth bottom part constituting walls 24 to 27 are continuously provided via lateral folding curves 20 to 23. Further, outer lid walls 30 and 31 are continuously provided on the upper portions of the first and third side walls 10 and 16 via lateral folding curves 28 and 29, and the second and fourth side walls 15 and 17 are connected. Horizontal curve 3 at the top
Inner lid walls 34, 35 are connected in series via 2, 33. Further, insertion pieces 38, 39 are continuously provided on the upper portions of the outer lid walls 30, 31 through lateral folding curves 36, 37, and a lateral folding curve 40 is provided on the upper portions of the inner lid walls 34, 35. , 41 and slits 42, 43 are provided to connect fastening portions 44, 45 which form a reinforcing member. In addition, insertion holes 46 and 47 into which the insertion pieces 38 and 39 are inserted are provided in the upper portions of the inner lid walls 34 and 35.

On the other hand, holes 48, 49 are provided in the fastening portions 44, 45,
As shown in FIG. 2, the holes 48, 49 have the fastening portions 44, 45 with the second and fourth side walls through the transverse bending curves 40, 41 and the slits 42, 43.
When folded back inside 15,17, the second and fourth side walls 1
5, 17 are formed so as to coincide with the handle holes 18, 19 formed in the holes 5, 19, and the fastening portions 44, 45 and the second and fourth side walls 15, 17 are formed.
The upper and lower sides of the overlapping handle holes 18 and 19 and holes 48 and 49 are adhered and fixed by glue. It should be noted that this gluing has an important meaning for the integrated effect of the gluing, rather than simply combining the second and fourth side walls 15, 17 with the fastening portions 44, 45. That is, the upper glue contributes to lifting the box, while the lower glue contributes to preventing damage to the box during pulling and improving stability when gripped.

Thus, according to the structure of the present embodiment, as shown in FIG. 2, when the fastening portions 44 and 45 are folded back inside the second and fourth side walls 15 and 17, the upper side of the holes 48 and 49 is increased. Since this portion is attached to the lower side of the handle holes 18 and 19, the entire periphery of the handle holes 18 and 19 is reinforced. Therefore, the handle hole 18,1
Even if the lower part of 9 is grasped and the box is pulled laterally, the box is not deformed, the lower parts around the handle holes 18 and 19 are not torn or cracked.

In addition, according to the structure of this embodiment, the size of the blanks is the same as that of the conventional one, so that the reinforcing effect can be improved without changing the cost.

Further, as a structure for reinforcing the entire periphery of the handle holes 18 and 19, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 52-64639. However, in this structure, since the hole corresponding to the handle hole is provided on the inner lid wall side instead of the fastening portion, the inner lid wall must be folded back inside the side wall. However, in the case of automatic box making using the hook of the suck machine, since it hooks on the hook and folds back, the structure described in the above publication does not catch on the hook.
I cannot make automatic boxes.

On the other hand, when the outer fastening portions 44 and 45 are folded back as in this embodiment, the free end can be easily hooked and bent, but the inner lid walls 34 and 35 are folded back because of the operation of the hook. Have difficulty. Therefore, between the two, handle holes 18,19
The technical idea is different in that it can be manufactured by an ordinary box-making machine even if it can function as a reinforcement.

FIG. 3 shows another embodiment of the box with a handle hole according to the present invention. In the above-described embodiment, the upper ends of the insertion pieces 38, 39 and the upper ends of the fastening portions 44, 45 are located in a horizontal straight line in the expanded state, and the slits 42, 43 of the folded portion are deeply cut. However, in the present embodiment, the fastening portion 4 is provided without changing the depth of the slits 42, 43 of the folded-back portion from the conventional depth.
4,45 are extended upward, and the second and fourth side walls 1 are provided on the extended portion.
Holes 48 and 49 that match the handle holes 18 and 19 of 5, 17 are provided. The rest of the configuration is the same as the configuration of the first embodiment described above, so further description is omitted. Of course, even with such a configuration, the same effect as that of the above-described first embodiment can be obtained.

[Effect of the Invention] As described above, according to the box with the handle hole according to the present invention,
The inner lid wall is continuously provided on the upper end side of the opposing side wall via a folding curve, and the fastening portion is continuously provided on the inner lid wall via the folding curve and the slit. By providing a hole at a position that coincides with the handle hole when the fastening portion is folded back to the inside of the opposite side wall, and by sticking and fixing both upper and lower sides of the handle hole of the fastening portion and the opposite side wall. When the fastening portion is folded back inside the opposing side wall, the fastening portion reaches below the handle hole, so that the entire periphery of the handle hole is reinforced. Therefore, even if the lower side of the handle hole is grabbed and pulled in the lateral direction, it is possible to reliably prevent the lower peripheral portion of the handle hole from being damaged as in the conventional case.
