Description

Packing box

Technical field

TECHNICAL FIELD [0001] The present invention relates to a packaging box used for an electronic device such as a television receiver.

Background art

[0002] Conventionally, when a thin television receiver such as a liquid crystal is transported, a top-center cushioning material is used between the top-left cushioning material and the packing box. The top and bottom cushioning materials were fixed inside the packing box because they were placed in the corners of the packing box. However, since the top center cushioning material is placed in the center, it was necessary to use a separate part such as an inner lid for fixing. For this reason, there was a problem that the cost was increased and the number of work steps was increased.

[0003] Japanese Patent Application Laid-Open No. 2004-106923 discloses a configuration in which the buffer material is fixed by extending the inner flap as a method of fixing the buffer material without increasing the number of parts. In other words, as shown in FIG. 21 [shown here], the cushioning member 2003 is fixed by applying the lids 2023A and 2023C of the outer box 2002 to the cushioning material 2003.

[0004] However, the packing boxes used for thin television receivers differ greatly in the ratio of width to depth. Therefore, in order to fix the top cushioning material based on the conventional configuration, the inner flap must be considerably long. Therefore, there are problems such as poor production efficiency and high cost, and poor handling at the time of distribution and packing at the factory. Disclosure of the invention

[0005] A packaging box of the present invention is a packaging box provided with a cushioning material for protecting a packaged object inside an outer box having at least a pair of flaps on one surface, and the pair of at least one pair of flaps. The inner flap includes a bent portion having at least one cut portion and a fold line portion, and each fold portion is bent at the fold line portion, and the tip of each bent portion is between the pair of inner flaps. It is characterized by sandwiching the installed cushioning material

[0006] In this way, the load at the time of physical distribution or the packing work in the factory without lengthening the inner flap. It is possible to provide a packing box with no problem in handling.
