Description

  The present invention relates to a packaging material suitable for housing long containers having the same cross-sectional size and different lengths, such as an electrophotographic toner container and a developer container.

  The electrophotographic toner container and developer container are mounted in a limited space of the electrophotographic copying apparatus in such a movable manner that the toner and developer can be gradually discharged by a required amount when the electrophotographic copying apparatus is in operation. In order to correspond to various types of electrophotographic copying apparatuses, there are a plurality of products having a cylindrical container, the same diameter, and different lengths (see FIG. 1). Conventionally, a plurality of packing boxes (FIG. 2) are also present along with the product. For this reason, there are multiple packaging boxes of similar sizes, and when manufacturing the packaging box itself, it becomes a typical small quantity and multi-product, and there is a problem that costs increase due to the time required for changing the size. there were. Further, the side that manufactures the toner and developer products has to manage a large number of packing materials, and there has been a business of ordering the materials.

It is not a packaging material for storing electrophotographic toner containers and developer containers, but as a general packing box, a part for fixing the product is provided in a part of the box, and the part is assembled to fix the product. The broad concept itself has been known for some time.
For example, in Patent Document 1, as shown in FIG. 16, it is formed integrally with a packaging box (22) for the purpose of providing a packaging device that reduces the number of packaging materials and improves the workability of packaging. The product contact part (31) is formed in a part of the part that closes the opening part of the packaging box (22), and the product contact part (31) regulates the position of the object to be packed. An apparatus is described.
However, the integrally formed product contact portion (31) has a complicated shape, and the workability is poor when producing the original plate shape. Also, when the contact portion (31) is assembled from above the box The workability is further deteriorated. Similarly, workability is poor when the installation portion (31) is assembled before manufacturing. Moreover, since the size of the packaging box becomes larger than before the contact portion (31) is provided, the cost of the packaging box itself also increases. In addition, no special device for packing products of different sizes with the same packaging material has been made.

  In Patent Document 2, as shown in FIG. 17, a part of the packaging box (1) is used to ensure that the product stored in the packaging box (1) can be reliably protected from impact and the like at low cost. It is described that a certain inner flap (4) is folded inward to form a hollow box-shaped buffer portion (6) inside the box body (2). In this case as well, the shape of the inner flap is complicated and the assembly workability is deteriorated. Further, since the size of the inner flap is increased, the cost of the packaging box is also increased. In addition, there is no description about a method of packing products of different sizes with the same packaging material.

In Patent Document 3, in order to provide a packaging container having a cost merit and an excellent buffering effect, as shown in FIG. 18, auxiliary flaps (10) (11) not used for forming the upper surface or the bottom surface of the container are used. ) (12) (13) are bent to form hollow buffer portions (10 ') (11') (12 ') (13'), which are arranged at the corners of the container, and the buffer portions ( 10 '), (11'), (12 '), and (13') describe the formation of notches (10 ₅ ), (11 ₅ ), (12 ₅ ), and (13 ₅ ) that fit into the package. In this case as well, the shape of the inner flap is complicated and the assembly workability is deteriorated. Again, there is no description on how to pack products of different sizes with the same packaging material.

  In Patent Document 4, in order to prevent the cushioning material arranged inside the cardboard packaging box from moving unnecessarily, as shown in FIG. 19, the bottom of the packaging box (1) is connected to the outer flap (1a) and the inner flap (1b). ), Two cuts (1c) are made at a predetermined interval in the center of the front end side of the inner flap (1b), and a portion surrounded by the two cuts (1c) is a cushioning material fixing member (1d) None, both ends of the cushioning material fixing member (1d) stood upright by folding up the base end of the cushioning material fixing member (1d) as a crease and folding up However, it touches the side surface of the shock absorbing material (2) arrange | positioned at the bottom part of the packaging box (1), and it is described that a shock absorbing material (2) does not move steadily. However, this technique is not related to the fixing of the packaged product itself, and there is no way to pay attention to the method of packing products of different sizes with the same packaging material.

  As described above, the technology for fixing the product by providing a part for fixing the product in a part of the conventional packaging box and assembling the part makes the assembly of the packaging box complicated, and the workability is poor. Moreover, there is a problem that the surface area of the packaging box is increased and the material cost is increased. Further, these conventional techniques do not make any knowledge of packaging materials suitable for housing long containers having the same cross-sectional size and different lengths.

As described above, there are a plurality of electrophotographic toner and developer containers having a cylindrical shape, the same diameter, and different lengths (see FIG. 1). Conventionally, a plurality of packing boxes (FIG. 2) are also present along with the product. For this reason, there are a plurality of packaging boxes of similar sizes, and the quantity of manufacturing the packaging box itself is small, and there is a problem that costs increase due to the time required for changing the size. Further, the side that manufactures the toner and developer products has to manage a large number of packing materials, and there has been a business of ordering the materials.
So, if you design the packing material for the product with the longest length and pack the product with the short length in it, the product will move during transportation, scratch the product, worst, cap etc. There was a problem that the contents leaked.
