The pair of opposing walls 30C are each formed with a shaft 30J that protrudes toward each other. Note that the circumferential length of the lock member receiving portion 30 is about 5 to 10 times the radial length.

Further, as shown in the figure, a notch 23K is formed in a portion of the lid skirt portion 23 located below the lock member receiving portion 30, which is cut upward from the lower end. The length of the notch 23K in the vertical direction is approximately half that of the lid skirt portion 23, and the length of the notch 23K in the circumferential direction is approximately the same as or slightly larger than the length of the lock member receiving portion 30 in the circumferential direction. ing.

As shown in FIG. 5, a handle 32 is provided at the center of the top surface of the lid body 21. In detail, in the vicinity of the two locking member receiving parts 30 among the outer edges of the bulging part 27, the bulging part A raised portion 31 having a V-shape in plan view is formed, which merges in front of the center of the portions 27 . Each of the protrusions 31 protrudes more from the entire bulge 27 as it goes from the outer edge of the lid 20 toward the center, and its side surfaces are inclined so as to narrow toward the top. A handle 32 is formed so that the upper ends of these two raised portions 31 communicate with each other. The handle 32 has the shape of a slightly curved strip so that the central part of the lid body 21 is the highest, and the upper surface thereof has a slightly depressed recessed portion 32U formed over the entire longitudinal direction of the strip. is formed.

A portion of the bulge 27 of the lid body 21 below the handle 32 is a central bulge 33 that bulges in a rectangular shape in plan view. Further, as shown in FIG. 8, the back sides of the raised part 31 and the central bulge part 33 are formed with corresponding side recessed parts 34 and central recessed parts 35, and as shown in FIG. 20 are stacked on top of each other, the handle 32 of the lower lid 20 is received in the central depression 35 of the upper lid 20. At this time, the upper surface of the handle 32 of the lower lid 20 comes into contact with the ceiling surface of the central depression 35 of the upper lid 20, thereby stabilizing the stacking.

Now, the locking member 40 is shown in FIGS. 10 and 11. The lock member 40 has a substantially doglegged cross section and extends in the longitudinal direction of the lock member receiving portion 30 (see FIG. 7). Specifically, as shown in FIG. 3, when the lid body 20 is locked to the container 11, the first band part 41 facing the bottom part 30A of the locking member receiving part 30 and the first band part 41 that is curved from the first band part 41, It has a second band part 42 that extends downward and overlaps the lid skirt part 23, and has a shaft hole 40J provided at the end of the first band part 41 opposite to the second band part 42 (see FIG. By inserting the shaft 30J (see FIG. 7) of the lock member receiving portion 30 into the lock member 40 (see FIG. 10), the lock member 40 is rotatable relative to the lid body 21. Note that the shaft hole 40J and shaft 30J correspond to the "rotation support section" in the claims.

As shown in FIGS. 3 and 11, at both longitudinal ends of the second band portion 42 on the opposite side to the first band portion 41, a container-side skirt of the container 11 protrudes toward the container 11 side. A locking claw 43 that locks at the lower end of the portion 13C is provided. This locking pawl 43 is disposed below the lower end of the lid skirt portion 23 and locks with the lower end of the container-side skirt portion 13C, thereby locking the lid body 20 with the container 11. The position of the locking member 40 at this time is appropriately referred to as a "first position." Further, the lower end of the container-side skirt portion 13C corresponds to the “locking portion” in the claims. Moreover, the space between the locking claws 43 in the second band portion 42 is a "receiving recess 44" in the claims (see FIG. 11). As shown in FIG. 1 etc., even if the locking member 40 is locked between the pair of facing plates 15 of the handle portion 14, there is a space between the locking member 40 and the gripping portion 16, so that the gripping portion 16 cannot be held. It is possible to grasp the part 16.

As shown in FIG. 10, the first band portion 41 of the locking member 40 has upright portions 45 that stand up from short sides facing each other in the longitudinal direction and from long sides opposite to the second band portion 42. is formed. The end portion of the short-side upright portion 45 opposite to the second band portion 42 is thick, and the above-mentioned shaft hole 40J is disposed in this end portion. Further, as shown in FIGS. 3 and 12, the long side upright portion 45 faces the back wall 30B of the lock member receiving portion 30. The locking member 40 is rotatable to a position (hereinafter referred to as the "second position" as appropriate) where the upright portion 45 on the short side abuts the back wall 30B of the locking member receiving portion 30 (see FIG. 13). ).

Here, as shown in FIG. 11, the locking member 40 of this embodiment is provided with a protrusion 50 projecting downward below the shaft hole 40J at both ends of the first band 41 in the longitudinal direction. ing. The projection 50 has a triangular shape when viewed from the axial direction of the shaft hole 40J, and the distance from the center of the shaft hole 40J in the lock member 40 to the lower end of the projection 50 is equal to the center of the shaft 30J in the lock member receiving portion 30. It is larger than the distance from the bottom part 30A to the bottom part 30A. As a result, as shown in FIG. 14, while the locking member 40 is being rotated from the second position to the first position, the projection 50 comes into contact with the bottom 30A of the locking member receiving part 30, and the locking member 40 is held. Ru. This position corresponds to the "special rotation position" in the claims. In this special rotation position, the tip of the locking member 40 (latching pawl 43) is located above the lower end of the lid skirt portion 23 (see FIG. 16). Then, after the locking member 40 further rotates downward and the projection 50 passes over the bottom 30A of the locking member receiving portion 30, the locking pawl 43 locks with the lower end of the container side skirt portion 13C. The lid 20 is locked to the container 11. Note that the protrusion 50 and the bottom portion 30A of the lock member receiving portion 30 correspond to a “holding portion” in the claims.

The structure of the lidded container 10 of this embodiment is as described above. Next, the effects of the lidded container 10 will be explained. When transporting the lidded container 10 or attaching/detaching the lid 20, only the lid 20 may be placed on the installation surface (for example, the ground, the top surface of a pallet, etc.). At this time, according to the lid body 20 of the present embodiment, the protrusion 50 of the locking member 40 comes into contact with the bottom 30A of the locking member receiving portion 30, so that the tip of the locking member 40 (locking claw 43) Since the locking member 40 is held at the special rotation position located above the lower end of the skirt portion 23, the lid 20 can be mounted without the tip of the locking member 40 (locking pawl 43) coming into contact with the installation surface. Therefore, damage to the lock member 40 can be prevented. This makes it possible to stabilize the locking of the lid 20 to the container 11, making it difficult for the lid 20 to come off, for example, even if the container 10 with a lid falls down.

Furthermore, when transporting the lidded container 10, it is conceivable that the container 11 and the lid body 20 are stacked separately and transported. As shown in FIG. 9, when the lids 20 are stacked on top of each other, the upper surface of the handle 32 of the lower lid 20 comes into contact with the ceiling surface of the central depression 35 of the upper lid 20, resulting in stable stacking. be done. Here, since a notch 23K is formed in the lid skirt portion 23 of the lid 20, when the lids 20 are stacked so that the locking members 40 overlap each other vertically, the notch of the upper lid 20 The locking member 40 of the lower lid body 20 is received at 23K. As a result, the lids 20 can be stacked even when the locking member 40 is held at the special rotation position, and the stacking height of the lids 20 can be reduced, improving the efficiency of transportation and storage. improves. Further, since the height of the notch portion 23K is suppressed to about half the height of the lid skirt portion 23, a decrease in the strength of the lid skirt portion 23 and a decrease in sealing performance can be suppressed.

Next, attachment and detachment of the lid body 20 will be explained. First, when removing the lid body 20 from the container 11, the locking members 40 are locked by hooking your fingers on the receiving recesses 44 or the locking claws 43 of the two locking members 40 and rotating the locking members 40 upward. (See Figure 15). Then, by lifting the lid 20, the lid 20 is removed from the container 11 (see FIG. 16). At this time, if the lock member 40 is rotated to the special rotation position, the tip of the lock member 40 (locking pawl 43) is held in a state located above the lower end of the lid skirt part 23. When lifting the lid 20, the locking member 40 can be lifted smoothly without being caught on the container 11.

When attaching the lid 20 to the container 11, the procedure is reversed. That is, the lid 20 is fitted into the container 11 with the lock member 40 held at the special rotation position. Then, the locking member 40 is rotated downward to elastically deform the projection 50 or the bottom 30A of the locking member receiving portion 30 to cause the projection 50 to ride over the bottom 30A of the locking member receiving portion 30, and then the locking member 40 is engaged. The retaining claw 43 is engaged with the lower end of the container side skirt portion 13C. This locks the lid 20 to the container 11.

Here, in this embodiment, the location where the locking claw 43 of the locking member 40 locks is the lower end of the container-side skirt portion 13C provided around the entire circumference of the container 11, so the locking member 40 can be placed. The range is wide, and the degree of freedom in attaching the lid body 20 is high (FIG. 1 etc. show an example in which the locking member 40 is arranged between a pair of opposing plates 15 of the handle part 14. FIG. 4 shows an example in which the locking member 40 is disposed between two handle portions 14). Moreover, the locking member 40 is provided with a receiving recess 44 between the two locking claws 43, and as shown in FIGS. Even if arranged so as to straddle the opposing plate 15, the receiving recess 44 can receive the opposing plate 15 and the locking claws 43 can be locked on both sides thereof (both sides in the circumferential direction), so that the opposing plate 15 and the locking pawl 43 can be locked. The lid body 20 can be attached in any direction other than the direction in which the claws 43 overlap.
