The mounting cylinder 23 sandwiches the upper end portion of the mounted cylinder 12 together with the lower end portion 22A of the side wall portion 22 in the radial direction, and provides high sealing performance to prevent the contents from drying.

Next, the usage method of the box-shaped container 1 of the above structures is demonstrated.
First, at the time of distribution or display of the box-shaped container 1, for example, the surrounding cylinder 13 surrounds the mounting cylinder 23 of the lid 3 from the radially outer side over the entire circumference, and the outer peripheral edge of the annular projecting portion 23A of the mounting cylinder 23 is surrounded by The mounting cylinder 23 is in contact with the inner peripheral surface of the cylinder 13 and is undercut fitted to the mounted cylinder 12. In order to remove the lid 3 from the container body 2, it is necessary to elastically deform the mounting cylinder 23 of the lid 3 radially outward to release the undercut fitting with the mounted cylinder 12. Since the outer peripheral edge of the annular projecting portion 23A is in contact with the inner peripheral surface of the surrounding cylinder 12, elastic deformation of the mounting cylinder 23 outward in the radial direction is restricted. Therefore, it is difficult to easily remove the lid 3 from the container body 2.

Subsequently, when removing the lid 3 from the container main body 2 of the box-shaped container 1, first, the other end in the circumferential direction of the movable band part 16 is picked and pulled up to weaken the fixed band part 15 and the like. The connecting part 19 is broken. Then, the movable band portion 16 is pulled in the circumferential direction toward one end portion in the circumferential direction. Thereby, the weakening connection part 18 between the lower end of the movable belt | band | zone part 16 and the lower end of the to-be-mounted cylinder 12 of the container main body 2 is fractured | ruptured sequentially along the circumferential direction. After the weakening connection portion 18 is broken, the movable band portion 16 is rotated radially outward around one end portion in the circumferential direction, and the locking hole portion 15A formed at the other end portion of the movable band portion 16 is fixed to the fixing band portion. It is made to latch on the latching protrusion 16A formed in 15. At this time, since the vertical groove 16C is formed on the inner peripheral surface of the movable band portion 16, the movable band portion 16 can be easily along the fixing band portion 15 when folded around the one end portion and reversed. Placed in.
As a result, the portion of the mounting cylinder 23 of the lid 3 that is exposed by folding the movable band portion 16 is released from the restriction by the surrounding cylinder 13 and can be elastically deformed radially outward. Then, the lid 3 is removed from the container body 2 by placing a finger on this portion. Thereafter, the contents are taken out as appropriate.

According to the box-shaped container 1 having the above-described configuration, at the time of distribution or display, the surrounding cylinder 13 surrounds the mounting cylinder 23 of the lid 3 from the outside in the radial direction, so that the lid 3 is removed from the container body 2. Removal is restricted, and when removing the lid 3 from the container body 2, the movable belt portion 16 is broken and turned so as to be folded around one end portion thereof, and then the locking hole portion 15 </ b> A is formed. Since the movable belt portion 16 is not detached from the container body 2 by being engaged with the engagement protrusion 16A, the function of preventing unauthorized opening can be imparted to the box-type container 1 without generating waste at the time of opening.
Further, since the longitudinal groove 16C is formed on the inner peripheral surface of the movable band portion 16, the movable band portion 16 can be easily arranged along the fixing band portion 15 when the movable band portion 16 is folded around one end thereof. The locking hole 15A and the locking projection 16A can be easily locked. Here, since the outer peripheral surface of the movable band portion 16 is a smooth surface, the appearance of the movable band portion 16 before the lid 3 can be removed from the container main body 2 can be maintained.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the locking portion is a locking hole and the locked portion is a locking protrusion, but the locking portion is a locking protrusion and the locked portion is a locking hole. You may change suitably the structure of a part and a to-be-latched part. Further, a plurality of locking portions and locked portions may be provided.
A vertical groove is formed on the inner peripheral surface of the movable band portion and the outer peripheral surface is a smooth surface. A groove may be formed, and the shape of the movable band portion may be another shape.
The movable band part is turned around the other end part in the circumferential direction and folded back along the fixing band part, but is not necessarily fixed if the locking protrusion and the locking hole part can be locked. It is not necessary to be folded back along the belt.
Although the weakened connecting portion and the weakened connecting portion can be broken by being thin, they may be formed by other configurations such as a breakable bridge.
The lower end of the movable band portion is connected to the lower end of the mounted cylinder via the weakened connecting portion. It does not have to be done.
The movable band portion may be provided at a plurality of locations on the surrounding cylinder.
An annular protrusion is formed at the lower end of the mounting cylinder, and the outer peripheral edge of the annular protrusion is in contact with the inner peripheral surface of the surrounding cylinder, but may not be in contact with the inner peripheral surface of the surrounding cylinder.
The container body, the lid, the mounting cylinder, and the surrounding cylinder have an elliptical cylinder shape, but may have other shapes such as a square shape.

  According to the present invention, industrial applicability is recognized with respect to a box-shaped container provided with an unauthorized opening prevention function that does not generate waste at the time of opening.
