The lid body 20 of this embodiment includes an elastically deformable holding part 23 that holds the lower flange part 12, and a hinge part 26 that rotatably connects the holding part 23 to the closing part 21. has been done. Two holding portions 23 and two hinge portions 26 are each disposed at the rear end portion of the lid body 20 at intervals in the left-right direction Y.

FIG. 4(c) is an enlarged view of the vicinity of the holding portion 23 in FIG. 3. As shown in FIG. 4(c), the holding part 23 has an upper contact part 23a, a connecting part 23b, a lower contact part 23c, and a guide part 23d. The upper contact portion 23a is in contact with the lower flange portion 12 from above, and the lower contact portion 23c is in contact with the lower flange portion 12 from below. The lower contact portion 23c is in contact with the inner surface of the recess 12b formed on the lower surface of the lower flange portion 12. The upper contact portion 23a and the lower contact portion 23c are arranged at positions facing each other in the vertical direction Z with the lower flange portion 12 interposed therebetween. The connecting portion 23b connects the upper contact portion 23a and the lower contact portion 23c. The connecting portion 23b is formed in a C-shape when viewed in cross section along the up-down direction Z and the front-back direction X.

The guide portion 23d extends downward from the lower contact portion 23c. The guide portion 23d is inclined so as to gradually move toward the front as it goes downward. A gap in the front-rear direction X is provided between the front end of the guide portion 23d and the main body portion 11 of the container body 10.
The clamping part 23 is formed to be elastically deformable as a whole, and is configured to clamp the lower flange part 12 of the container main body 10 by a restoring force.

As shown in FIG. 4C, the hinge part 26 is located between the clamping part 23 and the closing part 21, and connects the clamping part 23 to the closing part 21. A groove 22b recessed upward is formed in the lower surface of the upper flange portion 22. In the portion where the groove 22b is formed, the thickness of the upper flange portion 22 is reduced, making it easy to elastically deform. In this embodiment, the portion of the upper flange portion 22 whose wall thickness is reduced by the groove 22b functions as the hinge portion 26.

Further, as shown in FIGS. 1 and 2, a fitting portion 25 is formed in the lid body 20. The fitting portion 25 is located at the center of the closing portion 21 in the left-right direction Y and at the rear end of the closing portion 21 . The fitting part 25 is located between the two clamping parts 23 in the left-right direction Y. The left end surface and right end surface of the fitting portion 25 are tapered surfaces 25a. Each tapered surface 25a gradually extends toward the center in the left-right direction Y as it goes upward. Thereby, the length of the fitting portion 25 in the left-right direction Y gradually becomes smaller as it goes upward. The length of the lower end portion of the fitting portion 25 in the left-right direction Y is greater than the distance between the two clamping portions 23 . The length of the upper end portion of the fitting portion 25 in the left-right direction Y is smaller than the distance between the two clamping portions 23 .

As shown in FIG. 3, the lid 20 is formed with ribs 24 that protrude downward from the top wall of the closing portion 21. As shown in FIG. The rib 24 is formed from the top wall of the closing part 21 to the peripheral wall thereof, and faces the stepped part 11b of the container body 10 in the vertical direction Z. A plurality of ribs 24 are arranged at intervals in the circumferential direction. The ribs 24 increase the rigidity of the closing portion 21. Further, when the lid 20 is moved in the left-right direction Y relative to the container body 10 in the closed state, the rib 24 comes into contact with the upper cylinder portion 11c of the container body 10. Therefore, the ribs 24 restrict the displacement of the lid 20 in the left-right direction Y with respect to the container body 10.

Next, the operation of the lidded container 1A configured as above will be explained.

When assembling the lidded container 1A, as shown in FIG. 4(a), the lid 20 is placed above the container main body 10 and brought closer to the container main body 10. At this time, the holding part 23 is in a state in which the connecting part 23b is located above the hinge part 26.

Next, as shown in FIG. 4B, the holding part 23 is rotated downward around the hinge part 26 while the upper flange part 22 and the lower flange part 12 are in contact with each other. At this time, while the guide portion 23d slides against the rear end portion of the lower flange portion 12, the clamping portion 23 as a whole is elastic so that the gap between the upper contact portion 23a and the lower contact portion 23c widens. transform.

When the holding part 23 is further rotated downward around the hinge part 26, the lower contact part 23c enters into the recess 12b of the lower flange part 12, as shown in FIG. 4(c). Then, the flange portion 12 is held between the upper contact portion 23a and the lower contact portion 23c, and the lid 20 is connected to the container body 10. Thereby, the lid body 20 is connected to the container body 10 in a rotatable state around the hinge portion 26.

When the lid body 20 is rotated upward around the hinge portion 26 from the state shown in FIG. 4(c), a part of the fitting portion 25 (see FIG. 1) enters between the two clamping portions 23. . Since the fitting portion 25 has a tapered surface 25a, when the lid body 20 is further rotated, the fitting portion 25 is press-fitted between the two clamping portions 23. Thereby, the lid body 20 can be maintained in an open state.

As described above, according to the lidded container 1A of the present embodiment, the lid body 20 includes the clamping part 23 that clamps the lower flange part 12, and the clamping part 23 is rotatably connected to the closing part 21. A hinge portion 26 is formed. With this configuration, the upper end opening of the container body 10 can be easily opened by rotating the lid body 20 with respect to the container body 10 around the hinge portion 26. Further, since the holding portion 23 holds the lower flange portion 12, the state in which the lid body 20 is connected to the container body 10 is maintained. Therefore, operability can be improved.
Moreover, the mass and manufacturing cost of the lid 20 can be reduced compared to, for example, a case where the lid 20 is provided with a peripheral wall surrounding the lower flange portion 12.

Moreover, the lidded container 1A is configured such that the lid body 20 is connected to the container body 10 by the gripping portion 23 gripping the lower flange portion 12. Therefore, as shown in FIG. 4(a), the lid 20 can be separated from the container body 10 before assembly. Therefore, when filling the container body 10 with contents, the lid 20 is prevented from occupying the space of the filling line. Therefore, it becomes easier to arrange the container bodies 10 closely on the filling line, and filling efficiency can be improved.

Furthermore, the holding part 23 includes an upper contact part 23a that contacts the upper surface of the lower flange part 12, a lower contact part 23c that contacts the lower surface of the lower flange part 12 (inner surface of the recess 12b), and an upper contact part 23a and a lower contact part 23a that contacts the upper surface of the lower flange part 12. It has a connecting part 23b that connects the contact parts 23c to each other, and a guide part 23d extending downward from the lower contact part 23c. With this configuration, as shown in FIGS. 4(a) to 4(c), when the lid body 20 is assembled to the container body 10, the guide part 23d is brought into sliding contact with the lower flange part 12, and the guide part 23d guides the lid body 20. The lower abutting portion 23c that has been lowered can easily enter the lower side of the lower flange portion 12. Thereby, the assembly work of the lidded container 1A can be facilitated.

Further, since at least a portion of the holding portion 23 (lower contact portion 23c) is located within the recess 12b of the lower flange portion 12, the holding portion 23 is difficult to be disengaged from the lower flange portion 12. Therefore, the lid body 20 is prevented from accidentally coming off from the container body 10, and the operability can be further improved.

Further, the recess 12b is formed along the entire circumference of the lower flange portion 12 along the shape of the upper end portion of the main body portion 11. Therefore, when the container body 10 is viewed from below, the recess 12b is formed in a substantially rectangular shape. That is, the recessed portion 12b has a long side portion extending along the left-right direction Y and a short side portion extending along the front-rear direction X. A portion of the holding portion 23 is located inside the long side portion of the recess 12b. With this configuration, when an attempt is made to move the lid 20 in the left-right direction Y with respect to the container body 10 with the lid 20 open, the inner surface of the recess 12b at the transition from the long side to the short side The holding portion 23 makes contact. This restricts movement of the lid 20 relative to the container body 10. Therefore, the recess 12b and the clamping part 23 also have the role of regulating the movement of the lid 20 in the left-right direction Y with respect to the container body 10 when the lid 20 is opened.

(Second embodiment)
Next, a second embodiment according to the present invention will be described, which has the same basic configuration as the first embodiment. Therefore, similar configurations will be given the same reference numerals and their explanations will be omitted, and only the different points will be explained.

In the lidded container 1B of this embodiment, as shown in FIG. 5, a clamping part 23 and a hinge part 26 are formed at both the front end and the rear end of the lid 20. The configurations of each holding part 23 and each hinge part 26 are the same as in the first embodiment. That is, the front clamping part 23 clamps the front part of the lower flange part 12, and the rear clamping part 23 clamps the rear part of the flange part 12.

In the case of this embodiment, by elastically deforming the front or rear holding part 23 to release the lock from the lower flange part 12, the lid body 20 is rotated relative to the container body 10, and the lid body 20 is rotated relative to the container body 10. 10 can be opened. Therefore, it is possible to open the lid body 20 from either the front side or the rear side, and the operability is further improved.

Note that the technical scope of the present invention is not limited to the embodiments described above, and various changes can be made without departing from the spirit of the present invention.

For example, in the first embodiment, two holding parts 23 and two hinge parts 26 are provided, but the number of holding parts 23 and hinge parts 26 may be one or three or more.

In addition, the components in the embodiments described above can be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the embodiments and modifications described above may be combined as appropriate.
