Description

  The present invention relates to a packaging box used for accommodating, for example, a filter element for an air cleaner.

  Conventionally, a packaging box such as this type of filter element is generally constructed using cardboard and is formed in a shape that matches the size and shape of the object to be accommodated. Therefore, since packaging boxes that match the size and shape of the items to be stored are prepared for each type of items to be stored, it is avoided that the number of types of packing boxes increases and the cost required for manufacturing the packing boxes increases. Can not. In addition, in order to use a common packaging box, when a small container is stored using a large-capacity packaging box, the container is rattled in the storage space. In the case of display in the market, the product value may be reduced.

  As configurations that can cope with these problems, there are also configurations described in Patent Document 1 and Patent Document 2, for example. In the conventional configuration described in Patent Literature 1, a partition is provided in the box, and the object to be accommodated is slanted by contact with the partition, so that the amount of the object can be increased or decreased. In the conventional configuration described in Patent Document 2, the stopper piece in the box regulates the movement of the object to be accommodated at the edge thereof, so that it can cope with the objects of different sizes.

  In the conventional configuration of Patent Document 1, the side surface of the flat partition is in contact with the object to be stored, so that it corresponds to the objects to be stored having different sizes only depending on the inclination angle of the partition. . Therefore, in the structure of this patent document 1, it cannot respond flexibly to the change of the magnitude | size and shape of a to-be-contained object. That is, this Patent Document 1 has a narrow correspondence width with respect to the objects to be accommodated, and it is difficult to accommodate various objects to be accommodated having different sizes and shapes.

  Moreover, in the conventional structure of patent document 2, since the to-be-contained object is controlled in the edge of a stopper piece, the restriction | limiting depends on the dimension from the base of a stopper piece to an edge. For this reason, it can respond to only one type of object to be stored, and is less flexible than the conventional configuration of Patent Document 1 for the type of object to be stored.

As described above, neither Patent Document 1 nor Patent Document 2 has a sufficient function to cope with the size and shape of the objects to be accommodated, so it is necessary to prepare various types of packaging boxes.
The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide a packaging box that can be shared for accommodating objects to be stored having different sizes and shapes, and that can reduce the manufacturing cost of the packaging box.

It is characterized by providing a pressing piece that can be used to press the object to be contained.

  Therefore, in the packaging box of the present invention, even when the objects to be stored having different sizes are stored, the objects to be stored are pressed and held in the packaging box by the elasticity of the pressing pieces. Therefore, unlike the conventional configuration, there is no need to prepare various types of packaging boxes that fit the size of the items to be stored. The cost required for manufacturing can be reduced. In addition, since the object to be stored is pressed and held by the holding piece, even when a small object is stored in the packaging box, the object can be held without rattling.

  The said structure WHEREIN: It is good to provide the said holding | suppressing piece in the edge part of at least one side plate among right-and-left side plates. When configured in this manner, the holding piece can be easily folded into the packaging box, and the holding object is pressed and held in the packaging box by bringing the holding piece into contact with the outer surface of the holding object. can do.

  The said structure WHEREIN: It is good to form a crease line in the front-end | tip part of the said pressing piece. When configured in this manner, the tip of the pressing piece can be bent along the crease line and brought into pressure contact with the outer surface of the object.

  The said structure WHEREIN: It is good to form the perforation for isolation | separation in the base end part of the said pressing piece. In the case of such a configuration, when the pressing piece is unnecessary, the pressing piece can be easily separated from the perforation and removed.

  The said structure WHEREIN: It is good to form the perforation for dividing | segmenting the press piece in the width direction in the said press piece. When comprised in this way, a holding piece can be divided | segmented into the width direction from a perforation, and those division pieces can be contact | abutted with another outer surfaces, such as the upper surface of a to-be-contained object, and a back surface.

  As described above, according to the present invention, it can be used for the accommodation of objects to be stored having different sizes, the cost required for manufacturing the packaging box can be reduced, and the objects to be stored can be stabilized. The effect of being able to be accommodated is exhibited.
