It can be prevented from coming off. Further, since the flange portion 140 and the flange portion 240 are vertically overlapped and in contact with each other, it is possible to prevent dust or the like from entering the inside of the container 300 from the outside. Further, in FIG. 3C, the engaging portion 150 of the lid body 100 and the engaged portion 250 of the container body 200 are engaged with each other with a slight gap in the vertical direction. The engaging portion 150 and the engaged portion 250 may have the same shape and be engaged with each other in close contact with each other. Further, since the flange portion 240 around the engaged portion 250 is reversibly deformed, the lid body 100 can be repeatedly engaged with the container body 200.

As described above, according to the container 300 of the present invention, the flange portion 240 of the container body 200 is formed with a pair of recesses 260 on both sides of the engaged portion 250, and the lid 100 is engaged with the container body 200. When the engaging portion 150 is brought into contact with the engaged portion 250, the flange portion 240 around the engaged portion 250 is elastically deformed downward, so that the lid 100 can be easily engaged with the container body 200. ing. In particular, when the worker seals the container 300, the engaging portion 150 comes into contact with the engaged portion 250 by simply pushing the central wall 120 side of the lid 100 downward lightly, and the area around the engaged portion 250 Since the flange portion 240 is easily elastically deformed downward, the lid 100 can be easily and surely engaged with the container body 200. Further, even when the container 300 is sealed by using an engaging device instead of the worker, the engaging portion 150 is covered by simply pushing the central wall 120 side of the lid 100 downward lightly. Since the flange portion 240 around the engaged portion 250 is easily elastically deformed downward in contact with the engaging portion 250, the lid 100 can be easily and surely engaged with the container body 200.

Further, after the lid 100 is engaged with the container body 200, the flange 240 around the engaged portion 250 is reversibly deformed and returned to the original state before the elastic deformation, so that the lid 100 is lifted upward. Even if the lid 100 is engaged, the engaging portion 150 of the lid 100 engages with and is locked with the engaged portion 250 of the container body 200, so that the lid 100 can be prevented from being inadvertently disengaged. As described above, in the container 300 of the present invention, the lid 100 is easily engaged with the container body 200, while the lid 100 is difficult to be disengaged from the container body 200.

Further, according to the container 300 of the present invention, since the lid body 100 includes a vertically long rib 170 that connects the side wall 130 and the flange portion 140, the lid body 100 is engaged with the container body 200 when the lid body 100 is engaged with the container body 200. The force applied downward from the central wall 120 side of 100 is transmitted from the central wall 120 to the side wall 130 and the vertically elongated rib 170, and is effectively transmitted to the flange portion 140 via the vertically elongated rib 170. Therefore, the engaging portion 150 of the flange portion 140 of the lid 100 more reliably elastically lowers the flange portion 240 around the engaged portion 250 of the container body 200 by the downward pressing force effectively transmitted. It can be deformed, and the lid 100 can be easily and surely engaged with the container body 200.

Further, as shown in FIGS. 1 and 2, the engaging portion 150 of the lid 100 is provided at the corner portion 110, and the engaged portion 250 of the container body 200 corresponds to the position of the engaging portion 150. Although it is provided at the corner portion 210 of the container body 200, the present invention is not limited to this, and the engaging portion 150 may be provided at the side portion of the lid 100 and the engaged portion 250 may be provided at the side portion of the container body 200. good. However, when the lid body 100 is polygonal, the rigidity around the corner portion is higher than the rigidity of the side portion. Therefore, if the engaging portion 150 is provided at the corner portion, the lid body 100 is engaged with the container body 200. Since the downward pressing force is strongly transmitted by the engaging portion 150, the lid body 100 can be easily and surely engaged with the container body 200. Further, the vertically elongated rib 170 is provided at the corner portion 110 of the lid body 100, but the present invention is not limited to this, and the vertically elongated rib 170 may be provided at the side portion of the lid body 100. However, when the lid 100 is polygonal, the rigidity around the corners is higher than the rigidity of the sides. Therefore, it is better to provide the vertically elongated ribs 170 at the corners when engaging the lid 100 with the container body 200. Since the downward pressing force is strongly transmitted to the flange portion 140 and the engaging portion 150 via the vertically elongated rib 170, the lid body 100 can be easily and surely engaged with the container body 200.

Further, as shown in FIG. 1, the engaging portion 150 is located on an extension line of the end 172 of the vertically elongated rib 170 of the lid body 100. In other words, in a plan view, the vertically elongated rib 170 and the engaging portion 150 of the lid 100 are aligned in a straight line. Therefore, the force when the lid 100 is put on the container body 200 and pressed downward is directly transmitted from the vertically elongated rib 170 by the engaging portion 150, so that the lid 100 is easily and surely engaged by the container body 200. Can be combined.

Further, as shown in FIG. 2D, the recess 260 has a shape cut out in the skirt portion 241 of the flange portion 240 so as to go upward from the tip. Therefore, the flange portion 240 can be easily elastically deformed downward about the notched portion on the tip end side of the recess 260, but is less likely to be elastically deformed on the opposite upper side. Therefore, since the flange portion 240 around the engaged portion 250 is easily elastically deformed downward, it is easy to engage the lid 100 with the container body 200, but on the other hand, the flange portion 240 around the engaged portion 250 is Since it is hard to be elastically deformed upward, it is difficult for the engaging portion 150 and the engaged portion 250 to be disengaged, and it is possible to prevent the lid 100 from being inadvertently disengaged from the container body 200.

Further, as shown in FIG. 1, according to the lid body 100 of the present invention, the circumference of the lid body 100 protrudes downward from the flange portion 140 between the flange portion 140 provided with the engaging portion 150 and the side wall 130. A groove 160 extending in the direction is provided. Therefore, when the lid 100 is engaged with the container body 200, it is possible to effectively prevent dust and the like from entering the container 300 through the flange portion 140. Further, since the vertically long rib 170 extends from the side wall 130 to the flange portion 140 so as to cross the groove portion 160, the rigidity of the flange portion 140 around the groove portion 160 is improved. Therefore, when the lid 100 is engaged with the container body 200, even if the lid 100 is pushed downward, the flange portion 140 does not sink from the groove 160 as the starting point, so that the engagement provided in the flange portion 140 is provided. The portion 150 can be firmly engaged with the engaged portion 250 of the container body 200.

Further, since the vertically long rib 170 connects the side wall 130 and the flange portion 140, the downward pressing force applied to the lid 100 when the lid 100 is engaged with the container body 200 is the vertically long rib. It is effectively transmitted to the flange portion 140 via 170. Therefore, the vertically long rib 170 reinforces the flange portion 140, and the force for pushing the lid 100 downward at the time of engagement is firmly transmitted to the engaging portion 150, so that the lid 100 is transferred to the container body 200. It can be reliably and easily engaged.

Further, according to the lid body 100 of the present invention, since the vertically elongated rib 170 has a shape that spreads toward the end 172 from the tip end 171, when the lid body 100 is engaged with the container body 200, the lid body 100 is used. The force applied downward from the central wall 120 side is transmitted so as to spread uniformly from the terminal 172 side of the vertically extending rib 170 to the flange portion 140. Therefore, the force that pushes the lid 100 downward at the time of engagement is more firmly transmitted to the flange portion 140 and the engaging portion 150, so that the lid 100 is securely and easily engaged with the container body 200. It can be made to.
