  It is fixed to the container body by the crease line at the opening of the container body with a bottomed cylindrical shape. The top is divided into a fixed part that attaches and an opening and closing part that rotates and opens and closes using the fold line as a hinge. A box-shaped container (actual open flat 3-534) configured by externally assembling a short tubular lid. No. 63) is known.

[0003]   In the conventional box-shaped container described above, the opening edge of the container body and the upper end of the cylinder wall are directed outward. It has a structure in which it is bent and inverted into an L shape, and a seal projection is provided on the upper end of the inner peripheral surface of the cylinder wall. With the assembly that fits the opening edge of the container body to the peripheral edge of the lower surface of the top wall of the lid The outer cylinder wall piece and the inner cylinder wall piece that form the groove are provided, and the outer peripheral surface of the inner cylinder wall piece is closely sealed to the seal projection. Locking by contacting with the opening edge of the container body from below on part of the inner peripheral surface of the outer cylinder wall piece A ridge is projected, and the knob is attached to the outer peripheral wall of the outer cylinder wall that is far from the locking ridge. It is extended to the direction.

[0004]   Open and close the lid with the lid firmly attached to the container body with the fixing portion of the lid. Uses the fold line as a hinge to rotate and open and close. Seal the container body with the opening edge of the container body fitted in the groove for assembling the lid. Place the inner cylinder wall piece of the lid in close contact with the ridge and fit the opening edge of this container body into the assembly groove. Is held by locking the locking ridges of the lid to the opening edge of the container body. Therefore, the container is closed with relatively high airtightness.

[0005]   When opening the container from this closed state, grasp the knob with your fingertips and pull the open / close part of the lid. Although it is lifted up, since the tab and the locking ridge are located separately, By pulling up, it is easy to unlock the locking ridges on the opening edge of the container body.

The most effective use of this prior art is to place the tab on the “corner” part. It will be a configuration that can be demonstrated.

[0007]

[Problems to be solved by the device]

  However, in the above-mentioned conventional technique, the opening edge of the container body is attached to the lid by the outer cylinder. The inner cylinder wall piece of the lid is inserted into the assembling groove formed by the wall piece and the inner cylinder wall piece. Airtight closing of the container body by the lid by closely contacting with the seal ridge of the container body Is achieved and maintained, the container wall provided with the seal ridge and the cylinder wall and When the inner cylinder wall piece of the lid and lid is a simple cylindrical structure molded with a constant radius of curvature, The close contact of the inner cylinder wall piece with the sealing ridge is achieved almost uniformly over the entire area. However, in the case of the rectangular tube structure, the radius of curvature of the “corner” part is larger than that of the “side” part. Of the inner cylinder wall piece against the seal ridge at this "corner" because the Contact is not achieved, which causes the airtight chain of the container body by the lid to deteriorate significantly. There was a problem.

[0008]   Also, for the same reason as described above, the opening edge of the container body at the “side” part Compared with the strength of the fitting assembly between the assembly groove of the lid and the assembly groove of the lid, The strength of the fitting between the opening edge and the groove for assembling the lid is such that the inner cylinder wall piece is in close contact with the seal ridge. What you cannot do and make sure that the locking ridges that lock the opening edge of the container body are not profitable. And and are much weaker, which makes it easier to close the lid when the container is closed. Instability occurs, and there is no proper sense of resistance when opening and closing the lid. There was a problem that the closed state could not be felt by touch.

[0009]   Therefore, the present invention was devised to solve the above-mentioned problems in the conventional example. Therefore, even for the "corner" part of the opening edge of the container body molded into a bottomed rectangular tube structure, The "corner" part of the assembly groove formed on the lid body is the same as other "side" parts on the inner cylinder wall. The technical issue is to fit the piece in close contact with the seal ridge, and Ensures the airtight closure of the container body by the body and is suitable for opening and closing the lid The purpose is to give a sense of resistance.

[0010]

[Means for Solving the Problems]

  Means of the present invention for solving the above technical problems are A rim cylinder wall with an L-shaped cross section bent downward at the upper edge of the outer peripheral surface of the cylinder wall having a rectangular cylinder shape. A bottomed corner in which one piece is provided and a seal ridge with a low protruding height is provided around the upper end of the inner peripheral surface of the cylinder wall. Having a tubular container body, An outer cylinder wall piece having a low height is hung from the peripheral edge of the lower surface of the top wall to form a topped short-angled cylinder shape. Cage, which is attached to the outer shape of the container body so as to close the opening, and the container line A fixed part that is fixedly attached to the body, and an opening and closing part that rotates and opens and closes using this fold line as a hinge Having a lid divided into On the lower surface of the top wall of the opening / closing part of the lid body, between the outer cylinder wall piece, the cylinder wall upper edge and the lip cylinder wall piece. An assembly groove is formed in which the opening edge of the container body, which is composed of The inner cylinder wall piece in the shape of a short cylinder that hangs closely with the projections. At the lower end of the inner peripheral surface of the lid, avoiding the corners of the outer cylinder wall piece, attach the edge cylinder wall piece of the container body. Providing a locking projection that locks to the lower edge, Attaching a knob piece extending outward to the outer peripheral surface of the corner portion of the outer cylinder wall piece of the lid, On the inner peripheral surface of the corner portion of the outer cylinder wall piece of the lid, project a pressing projection piece that presses the rim cylinder wall piece of the container body. To set up, It is in.

[0011]

[Action]

  The lid body is a container main body composed of an upper end edge of the cylinder wall and a lip cylinder wall piece with respect to the container body. It is attached to the opening edge of the body in an external fitting manner, but for the attachment of this lid to the container body At this time, the fixing portion is firmly and immovably assembled and fixed to the container body.

[0012]   Therefore, the opening / closing part of the lid body is fixed to the container body with the fixed part as a stationary part. The fold line functions as a hinge, and is assembled so that it can be rotated and displaced in the opening and closing directions. Will be.

[0013]   When closing the container body by the opening / closing part of the lid, the opening edge of the container body should be placed in the opening / closing part. This can be achieved by fitting it in the groove for assembling. In this state, the locking ridge is locked to the bottom edge of the wall of the rim cylinder wall of the container body, and The seal ridge of the main body is in close contact with the outer peripheral surface of the inner cylindrical wall piece.

[0014]   Further, the pressing protrusions provided on the inner peripheral surface of the corner portion of the outer cylinder wall piece in the opening / closing portion of the lid body, Since the corners of the container cylinder wall piece are pressed inward, this pressing force is the same. The outer peripheral surface of the inner cylinder wall piece in the section is pressed against the seal ridge, which closes it. In this state, close contact between the inner cylindrical wall piece and the seal ridge at the corner can be achieved and maintained. Becomes

[0015]   To open the opening and closing part of the lid, pick the knobs made at the corners with your fingertips and move upward Achieved by raising to. At this time, the pulling force acting on the knob is Since the outer cylinder wall piece on the “side” is bent while being pulled up, it is attached to the lower edge of the lip cylinder wall piece. The locking ridge that has been stopped will be unlocked from the end of the rim cylinder wall piece. Therefore, the engagement of the locking ridge with the rim cylinder wall piece can be released smoothly with a comparatively weak operating force. Becomes

[0016]   When the lid is closed by the opening / closing part, the pressing protrusion presses the rim cylinder wall piece. As a matter of course, fit the assembly groove of the lid into the opening edge of the container body. During the closing operation, and when opening the lid assembly groove from the opening edge of the container body. At the time of releasing operation, due to this pressing, sliding friction resistance force is generated between the pressing projection and the rim cylinder wall piece. Occurs, and this resistance acts as resistance to the closing and opening operations.

[0017]   Therefore, the resistance force generated between the pressing protrusion and the rim cylinder wall piece causes the opening / closing of the lid. It provides a proper resistance to operation and gives a proper tactile sensation when opening and closing the lid. You can do it.

[0018]   In addition, the pressing of the pressing protrusion against the corner of the wall of the rim cylinder causes the lid body to be closed. Since it is maintained for the entire length of the container, the locking ridge is not Even at the corners of the lid that have a weak force to maintain a fixed posture with respect to the body, Due to the pressure, the assembled posture with respect to the container body is stably maintained.
