Description

  The present invention relates to an assembly container for storing powdery chemicals and the like, particularly to a large assembly paper tube.

  2. Description of the Related Art Conventionally, a container in which a circular container bottom is attached to a lower end edge of a cylindrical container body is often used as a container for storing powdery chemicals and the like. However, when the container body is cylindrical, the container body cannot be folded and is bulky. Therefore, there is a problem in that it costs storage and transportation even when the contents are not stored.

  Therefore, as shown in Patent Document 1, a cylindrical box body whose top and bottom are open, a container body consisting of a bottom material detachably attached to the bottom of the box body, and the top of the box body are fitted. The box body has an N-shaped horizontal cross section, extends from the N side body surfaces and the lower end of each side body surface, and bends inward. And a tongue piece having two side surfaces and an end surface, and the bottom surface material is a bottom surface body having an N-square planar shape substantially similar to the cross-sectional shape of the box body, and each of the bottom surface body It consists of a hanging piece that extends downward from the side, and a paperboard body that is affixed to the bottom surface of the bottom surface body and has a slightly smaller outer shape than the bottom surface body. The piece is in the space formed between the side body surface of the box body and the tongue piece. The bottom surface body of the bottom surface material is supported by the end surface of the tongue piece, and the end portion of the tongue piece is accommodated in a space formed between the hanging piece of the bottom surface material and the end surface of the paperboard body. An assembly-type box-like container characterized by the above has been proposed.

  By configuring in this way, it is easy to assemble and disassemble the container, and when the contents are not stored, the bottom material can be removed from the box body and the box body can be folded. The cost of transportation can be reduced.

  However, in the above-described configuration, when the container is assembled and folded, the container body and the bottom of the container are separated, so that it is easy to lose one of them, and it is necessary to combine separate parts when assembling. There is a problem of poor work efficiency. Furthermore, since the paperboard body is affixed to the lower surface of the bottom surface main body, thereby supporting the tongue piece extending from the lower end portion of the box main body, there is a problem that the bottom surface becomes complicated and costly. Therefore, it can be said that there is still room for improvement.

On the other hand, considering the work efficiency and the like, it is conceivable to integrally form the container body and the bottom of the container. However, in this case, there is a problem that the material handling is poor and the production cost is increased.
