Description

    The present invention relates to a packaging box for storing merchandise.

  Generally, when a certain product is shipped, the product is stored in a packaging box so as not to break the product or to bundle instructions, parts, etc. attached to the product. In the case where the product is small and the corresponding packaging box is also small, it is carried out by applying collective packaging in which a plurality of packaging boxes containing the products are put in one outer box. FIG. 7 shows a conventional collective packaging of packaging boxes, and four packaging boxes 55 are accommodated in one exterior box 51.

  As a method of taking out a plurality of packaging boxes 55 containing products from one exterior box 51 on which collective packaging has been applied as shown in FIG. 7, (1) using a gap formed when a plurality of packaging boxes 55 are stored. And (2) a method of attaching a separate part such as a ribbon to the packaging box 55 itself and taking it out through the separate part, or (3) a packaging box 55 with the exterior box 51 turned upside down. It is possible to take out.

  When the method (1) is adopted, the packaging box 55 is not able to be taken out because the hands are not put in the gaps created by storing the plurality of packaging boxes 55, or the packaging box 55 is heavy even if the hands are put. It is thought that it cannot slide out from the hand. Further, when the method (2) is adopted, the cost is increased by preparing a separate part dedicated to the packaging box 55, and the labor for attaching the separate part is required. When the method (3) is adopted, when the outer box 51 is turned upside down, the packaging box 55 may fall to the ground and damage the stored product.

Therefore, a method for easily removing the packaging box 55 from the exterior box 51 by providing a mechanism for easily removing the packaging box 55 stored in the exterior box 51 by hand in the structure of the packaging box 55 itself can be considered.
