Next, the structure of the movable member 4 will be described.

In the description of the structure below, directions such as up and down are based on the state in which the movable member 4 is in the closed position (see FIGS. 1 to 4, FIG. 8, etc.).

As shown in FIG. 9 and the like, the movable member 4 includes a support frame 41 that is U-shaped when viewed from the front, and a stepped plate 42 that extends inwardly D2 from the edge portion on the inner peripheral side of the support frame 41 . , a door plate 43 extending upward from the edge portion of the inner side D2 of the step plate 42 and a connecting portion 44 rotatably connected to the fixing member 3 are integrally provided.

The support frame 41 has a horizontal frame 412 that is long in the horizontal direction, and a pair of left and right vertical frames 414 that extend upward from both left and right ends of the horizontal frame 412 . A protrusion 416 protrudes outward D1 from the lower end of the lateral center portion of the horizontal frame 412 . The protrusion 416 is formed in a straight line in the left-right direction so that the user can hook a finger thereon.

The step plate 42 has a hooking portion 423 on which the hooking portion 333 of the fixing member 3 is hooked. The hook portion 423 is formed in the central portion of the step plate 42 in the left-right direction. The hooking portion 423 is a through hole penetrating vertically, but may be a non-penetrating groove.

The door plate 43 integrally has a plate-like substrate 431 extended from the step plate 42 and a curved plate 433 further extended upward from the substrate 431 .

When the movable member 4 is in the closed posture, the substrate 431 of the door plate 43 is positioned inside the handle hole 8 (see FIG. 3, etc.). The substrate 431 stands straight up from the edge portion of the inner side D2 of the step plate 42 . The curved plate 433 is entirely curved in an arcuate cross-section so that its tip protrudes outward D1. The tip of the curved plate 433 is positioned away from the handle hole 8 in the outer direction D1.

The convexly curved surface of the curved plate 433 forms the convexly curved surface 49 of the movable member 4 . The convex curved surface 49 is a surface that can be gripped by the user when the movable member 4 is in the open position (see FIGS. 5 to 7).

The connecting portion 44 is a pair of left and right shaft portions 441 formed at the upper end portions of the pair of left and right vertical frames 414 . The pair of left and right shaft portions 441 are projecting shafts protruding toward each other in the left-right direction (see FIGS. 9, 10, etc.).

Next, the operation of attaching the inner part 1, fixed member 3 and movable member 4 of the above structure will be described.

The inner part 1 is attached to the handle hole 8 of the rocking plate 95a from the inner side D2. The insertion wall 13 of the inner part 1 is inserted into the handle hole 8 of the rocking plate 95a.

The insertion wall 33 of the fixing member 3 is inserted into the handle hole 8 of the rocking plate 95a. A pair of left and right projecting flat portions 321 of the fixing member 3 are in contact with the rocking plate 95a.

With the insertion walls 13 and 33 inserted into the handle hole 8 from both the inner and outer sides, the insertion wall 33 of the fixing member 3 is positioned inside the insertion wall 13 of the inner part 1 and is inserted into the handle hole 8. Located along wall 13 (see FIG. 4). A pair of left and right locking portions 331 protruding from the insertion wall 33 are fitted into a pair of left and right locking portions 131 formed through the insertion wall 13 in a one-to-one manner. Thereby, the inner part 1 and the fixing member 3 are locked to each other.

The movable member 4 is rotatably attached to the fixed member 3 . The pair of left and right shaft portions 441 of the movable member 4 are fitted into the pair of left and right bearings 341 of the fixed member 3 (see FIG. 2, etc.). In this state, the movable member 4 is rotatable around the pair of left and right shaft portions 441 .

In a state in which the movable member 4 is connected to the fixed member 3 and no particular external force is applied to the movable member 4, the weight of the movable member 4 acts to maintain the closed posture.

When the movable member 4 is in the closed posture, the hooking portion 333 protruding from the fixed member 3 is elastically hooked on the hooking portion 423 penetrating the movable member 4 (see FIG. 3, etc.). As a result, the movable member 4 is maintained in the closed posture, and the contents of the container 9 are prevented from spilling out through the handle hole 8 .

When the movable member 4 is in the closed posture, the support frame 41 of the movable member 4 is positioned so as to cover the outer frame portion 31 of the fixed member 3 from the outer side D1. The door plate 43 of the movable member 4 is positioned so as to cover the handle hole 8 of the rocking plate 95a from the outer side D1.

When the movable member 4 is in the closed posture, the support frame 41 abuts against the outer frame portion 31 of the fixed member 3, and the movable member 4 cannot be rotated further inward D2. Therefore, according to the mounting member 7 of one embodiment, animals such as rats and insects are effectively prevented from entering the inside of the container 9 through the handle hole 8 .

For example, if the user hooks a finger on the projection 416 of the movable member 4 and applies an external force toward the outer side D1 to release the elastic hooking between the hooks 423 and 333, the movable member 4 is moved to the outer side D1. It can be turned towards (see arrow in FIG. 7).

As shown in FIGS. 5 to 7, the open posture of the movable member 4 is the posture when the movable member 4 is rotated most toward the outer side D1. The movable member 4 is rotatable within a range of 180 degrees. 180 degrees here is not strictly interpreted, and includes cases of about 180 degrees. When the movable member 4 is viewed along its rotation axis, the closed posture and the open posture of the movable member 4 are point symmetrical with respect to the rotation axis.

When the movable member 4 is in the open posture, the projection 416 of the movable member 4 abuts against the mouth frame 93 to restrict further rotation. The support frame 41 and the door plate 43 of the movable member 4 are positioned so as to overlap the mouth frame 93 of the container 9 in a front view, and the handle hole 8 of the rocking plate 95a is open. The user can grasp the handle hole 8 with the hand inserted from the outer side D1 without the movable member 4 becoming an obstacle.

When the movable member 4 is in the open position, the entire door plate 43 is positioned outward D1 from the handle hole 8 (see FIG. 7, etc.). At this time, the substrate 431 , which is the upper portion of the door plate 43 , is positioned above the handle hole 8 .

When the movable member 4 is in the open position, the substrate 431 hangs straight down from the edge portion of the outer side D1 of the step board 42 . A curved plate 433, which is a lower portion of the door plate 43, is curved in an arcuate cross-section so that its tip protrudes toward the inner side D2.

The convex curved surface 49 of the curved plate 433 is located at the lower portion of the movable member 4 when the movable member 4 is in the open position. The lower portion of the movable member 4 in the open posture is the portion of the movable member 4 closer to the handle hole 8 .

As shown in FIG. 7, the convex curved surface 49 in the open posture has a shape that smoothly bulges obliquely downward (downward toward the outer side D1). The curvature radius of the convex curved surface 49 is preferably set within a range of 2 to 13 mm, more preferably within a range of 5 to 10 mm. The radius of curvature here is the radius of curvature when the convex curved surface 49 is viewed from the left-right direction.

The direction of the convex curved surface 49 (orientation of the normal to that point) becomes closer to the horizontal direction at a point closer to the substrate 431 (upper point), and the orientation becomes closer to the horizontal direction at a point farther from the substrate 431 (lower point). It curves smoothly so as to be close to vertical downward.

After opening the movable member 4 to the outside, the user can insert his/her hand into the handle hole 8 from the outside and bring the convex curved surface 49 into contact with, for example, the palm of the hand. Since the convex curved surface 49 of the movable member 4 fits the hand, the user can hold the handle hole 8 and the convex curved surface 49 located on the outer side D1 of the handle hole 8 and hold the container while suppressing pain during operation. 9 transportation work can be performed.
