Description

[Detailed description of the invention] (Field of industrial application) The present invention is a method for packaging cylindrical containers such as bottles and tubes in which a storage space formed on both sides of a central partition wall is partitioned by a partition wall having a buffer space. This relates to a partition box.

(Prior Art) The inventor of the present invention previously devised a partition box for packaging cylindrical containers such as bottles and tubes, which had a structure in which storage sections were formed on both sides of a central partition plate.
This is disclosed as Publication No. 103309, but the buffer space is not formed between the storage parts, and the inventor of the present invention devised a partition piece with a buffer space formed therein. This is disclosed in Japanese Patent No. 62-45218, but the housing spaces are formed in a line.

(Problem to be Solved by the Invention) Therefore, in order to meet the demand for two rows of storage sections formed by partition pieces each having a buffer space, the inventor of the present invention developed the technique of the former of the known partition boxes. We devised and produced a prototype using the latter technique, but since there are many bent parts when the separator pieces are made to stand up, it is necessary to glue the pieces into a flat state and then make the separator pieces stand up to create a three-dimensional state. There were problems to be solved in that not only did a large amount of operating force be required to erect the separator piece, but also that the bent part was difficult to bend when the separator piece was raised, and the glued part was peeled off, making it impossible to form an orderly accommodating part.

This invention increases the adhesive area at both ends of the dividing piece that forms the buffer space to make it stronger, and also makes it easier to stand up the dividing piece, which has a holding effect that suppresses the movement of cylindrical containers such as bottles and tubes. It is an object of the present invention to provide a partition box for packaging cylindrical containers such as bottles and tubes, which exhibits a buffering effect to reduce collision forces between containers and can accommodate cylindrical containers in two rows.

(Means for Solving the Problems) Next, the partition box for packaging cylindrical containers such as bottles and tubes according to the present invention will be explained based on the drawings as follows.
