Description

  The present invention relates to a carton case with a corner handle hole for packing.

  As shown in FIG. 1, the conventional carton case has two locations corresponding to the facing position among the four side surfaces 14 existing in the vertical direction of the case (the vertical direction when used in a normal state). In this structure, a handle hole 12 is opened, and a handle (finger) is inserted into the handle hole 12 for transport. The handle hole 12 maintains strength only by the thickness of the carton case. When there is sufficient space inside the carton case, there is a space where the handle (finger) can be sufficiently hooked, but in other cases, the fingertip is only caught.

In the process of using the carton case in FIG. 1, when the handle is put into the handle hole 12 on the side surface, the contents often occupy the full volume up to the inner side surface of the carton case, and the handle (finger) can be sufficiently inserted. There was a problem that it was difficult to secure only a space. For this reason, when carrying a heavy object in a case and carrying it for a long time, the heavy load was put on the body (fingertip), when the weight was applied to the narrow range of the handle (finger) and it was carried for a long time. In some cases, there was a risk that the fingertip would come off and the carton case would fall.
Furthermore, since the handle hole 12 has only the strength of the thickness of the carton case, when carrying a heavy object, force is applied to the B part of FIG. 1 in the direction of the arrow (C direction), and the case is torn and damaged. There was also a problem of doing. For this reason, the contents sometimes jump out of the case, and there is a possibility that the contents are contaminated by breakage or dust.

  The conventional carton case with a handle string as shown in FIG. 2 is a small carton case in which the handle string 15 is inserted into two positions in the facing position among the four side surfaces existing in the vertical direction of the case, that is, two positions near the center of those surfaces. A structure in which a hole is made, and this hole is used as a handle attachment portion hole 13, and both ends of the string are inserted from the outer surface, and metal clasps are attached to both ends of the handle string 15 from the inner surface side to prevent pull-out. Thus, the handle string 15 is grasped and transported. The carton case containing the product is structured so that it weighs in two small holes on the left and right.

  In the process of using the carton case with a handle string shown in FIG. 2, there is a problem that a small hole of only the thickness of the carton case cannot withstand the load of a heavy object and breaks through the hole with the clasp of the handle string 15, The carton case sometimes dropped on the operator's feet during transportation. Further, since the materials of the carton case and the handle string 15 are different, recently, it has been required to carry out a separation process for each material when disposing, and this separation work is also a problem. In terms of price, the carton case, handle string, fasteners and parts were separated, and the problem was that it was expensive.

  An object of the present invention is to propose a carton case with good workability, in which the handle hole portion in the carton case is not easily damaged, and the finger is easily put on the handle hole portion.

  Therefore, in order to solve the above-described conventional problems, the present invention can increase the strength of the hole portion by providing the position of the handle hole portion at the corner portion that is originally strong from the side surface portion of the conventional method, and further provide an inner surface pad. In this way, it is possible to improve the strength and workability of the carton case itself.

  That is, according to the present invention, in a carton case in which one carton sheet is punched and formed, holes for handles are formed at two diagonal positions among four corners existing in the vertical direction of the carton case. The hole strength is improved by opening the handle hole at a corner having a relatively strong strength with respect to the surface of the carton case. In addition, since the handle holes are provided at the corners, it is easy for a finger to enter the corner space, and the structure can be easily held by a handle (finger).

  The position in the height direction of the handle hole in the carton case is basically the center in the height direction, but depending on the size of the carton case, especially the height, it may be higher than the center. Or can be provided below.

  The size of the carton case of the present invention is not particularly limited, but is usually 200 to 500 mm in length, 200 to 500 mm in width, 130 to 400 mm in height, and 3 to 10 mm in thickness. In addition, the size of the hole for the handle of the carton case is not particularly limited as long as it is a size that allows a hand to be gripped, but the length from the corner to the tip of the hole for the handle horizontally is 60 to 90 mm, and the upper and lower The standard width is 20-40 mm.

  Further, the inner pad with the crease shown in the development view in FIG. 6 is provided so as to overlap the inner vertical surface of the carton case, so that the strength of the carton case itself can be improved, and it is easy to secure a space for fingers to enter the inner corner. It is a way to solve problems. The term “overlap” means that the inner surface pad may be provided simply in contact with the inner vertical surface of the carton case, or a part or the whole surface may be adhered as necessary. In addition, the material of the carton case and the inner surface pad in the present invention is not limited, and any material may be used in combination, but it is preferable to use the same material. The carton case is usually made of paper, and in the present invention, it is preferable to use a combination of paper, but in some cases, both can be made of synthetic resin such as polyethylene.

  As mentioned above, according to the present invention, the handle (finger) is easy to enter the carton case because the handle hole part is not at the side of the carton case but at the corner where the gap is relatively easy. It became possible to hold. For this reason, when moving and transporting a carton case packed with products, it is easier to carry than a conventional product and can be transported physically.

  In terms of strength, in addition to the fact that the corner portion is originally a strong position, the force applied to the hole portion is complicatedly distributed, so that the strength of the handle hole portion is improved. This eliminates the risk of falling due to breakage, and allows safe work.

  Moreover, when the inner surface pad was used, the strength of the entire carton case was improved. In addition, it is now easy to secure a space for inserting a handle (finger) by using a pad, and even if the inside of a carton case is filled with a small package, the space can be secured. ing.

  Compared to the conventional carton case with handle straps of the type shown in Fig. 2, the carton case of the present invention is made of the same material for the carton case and the inner pad and does not use different handle straps or clasps. This eliminates the need for sorting work and improves the efficiency of the discarding work. In addition, since there is no handle string, there is less space for stock storage and the stock location can be used effectively. Also in terms of price, since one carton sheet is punched and molded, the number of parts is reduced and the cost is reduced.

In FIG. 4, the alternate long and short dash line is a fold line. When the development view is assembled, a handle hole portion is formed at a portion 2 in FIG. 3 which is a perspective view. A finger is put into this part to move and carry.
