  As shown in FIG. 8A, the lid-side hinge cylinder 21 is smaller than the interval between the body-side hinge cylinders 20, 20, so that the rotation lid 50 is in the direction of the rotation axis with respect to the container body 11. It is possible to move directly. Hereinafter, the side where the rotating lid 50 approaches the lid closing engagement portion 26 in the linear motion direction is referred to as “front side”, and the opposite side is referred to as “rear side”.

  As shown in FIG. 8B, when the rotating lid 50 is moved to the front side with the lid fully closed, the main body side hinge cylinder 20 and the lid side hinge cylinder 21 come into contact with each other and are positioned at the fully closed front end position. The lid closing engagement portion 26 is engaged with a protrusion receiving portion 58 described below in the lid 50, and the rotation of the rotation lid 50 is restricted. As shown in FIG. 7 (A), the protrusion receiving portion 58 is formed by recessing the corners of the lid lower surface reinforcing rib 55 and the band plate 52A of the lid upper surface flange 52, as shown in FIG. 10 (B). As described above, when the lid closing engagement portion 26 engages with the protrusion receiving portion 58, the lid closing engagement portion 26 faces the locking bottom surface 58 </ b> A at the bottom in the protrusion receiving portion 58 from above, and Regulates rotation. Further, as shown in FIG. 10A, an inner surface protrusion 59 is formed on the inner surface of the lid lower surface reinforcing rib 55 on the back side of the protrusion receiving portion 58, and the inner surface protrusion 59 has a lower surface. A guide slope 59A is formed by obliquely cutting a corner with the outer surface of the lid lower surface reinforcing rib 55.

  In the state where the rotating lid 50 is disposed in the fully closed front end position in the fully closed state, the position of the rotating lid 50 facing the locking hole 29A (see FIG. 3) of the container body 11 is on the lid side. Locking holes 52M (see FIG. 7A) are formed through. The rotating lid 50 can be locked in a closed state by aligning the locking holes 29A and the lid side locking holes 52M and inserting a padlock (not shown), for example.

The movement is restricted. Therefore, if the one end of the rotating lids 50, 50 is slightly lifted to disengage the upper surface stopper 30, the rotating lid 50 can be moved rearward. Then, when the rotating lid 50 is moved to the rear side, the locking protrusion 27 of the container body 11 and the inner surface protrusion 59 of the rotating lid 50 shown in FIG. 12 (B), one side surface of the second guide protrusion 57T on the back surface side of the belt receiving groove 57 shown on the left side shown in FIG. ), The engagement with the lid closing engagement portion 26 is released. At the fully closed rear end position, the rear end portion of the rotary lid 50 protrudes to the side of the container main body 11 by the dimension L1 shown in FIG.

  When the rotating lid 50 is rotated in a state in which the engagement with the lid closing engagement portion 26 is released, and the lid is fully opened (see FIG. 1) hanging from the hinge portion 16, the lid is fully closed. The range in which the rotation lid 50 can move directly with respect to the container body 11 is narrowed. Specifically, when the rotating lid 50 is moved to the front side with the lid fully opened, the main body side hinge cylinder 20 and the lid side hinge cylinder 21 are moved as shown in FIG. By contacting, the rotation lid 50 is positioned at the fully open front end position. At this position, the rotating lid 50 does not protrude laterally from the container body 11 in the direction of the rotation axis, and the end of the rotating lid 50 opposite to the lid closing engagement portion 26 is the end of the container body 11. It will be in the state which retracted only the dimension L2 shown in the figure from the part.

  Further, when the rotating lid 50 is moved to the rear side in the fully opened state, the side surface of the belt contact projection 18 and the inner side surface of the belt receiving groove 57 are in contact with each other as shown in FIG. The moving lid 50 is positioned at the fully opened rear end position. Even at this position, the rotating lid 50 does not protrude laterally from the container body 11 in the direction of the axis of rotation, and the end of the rotating lid 50 opposite to the lid closing engagement portion 26 is the end of the container body 11. And placed in the same position in the rotation axis direction. That is, the fully opened rear end position of the rotating lid 50 in the fully open state (see FIG. 9B) with respect to the fully closed rear end position of the rotating lid 50 in the fully closed state (see FIG. 8A). Is close to the front. Therefore, in order to guide the rotating lid 50 to the front side when the rotating lid 50 disposed in the fully closed rear end position is rotated in the opening direction in the fully closed state, the “first slide” according to the present invention is used. The “contact guide portion” is provided at the belt contact protrusion 18 and the edge of the belt receiving groove 57.

The protrusion 18 is detached from the belt receiving groove 57, and the lower end of the back surface of the belt receiving groove 57 (second guide protrusion 57T) is separated from the inside of the side wall upper recess 17. In this state, when a force is applied to the side where the rotating lid 50 is separated from the lid closing engagement portion 26, the rotating lid 50 is moved to the semi-closed rear end position where the main body side hinge cylinder 20 and the lid side hinge cylinder 21 abut. 50 moves away from the lid closing engagement portion 26 from the fully closed rear end position. Therefore, the “second sliding contact guide” according to the present invention is used to guide the rotating lid 50 arranged at the half-closed rear end position in the half-closed state to the full-closed rear end position when the lid 50 is rotated in the closing direction. Part "is provided at the lower edge of the second guide protrusion 57T and the upper edge of the side wall upper end recess 17. Specifically, of the pair of triangular slopes 17S, 17S of the side wall upper end recess 17 shown in FIG. 1, one triangular slope 17S disposed on the side away from the lid closing engagement portion 26 is related to the present invention. It is a “second sliding contact guide portion”. Further, as shown in FIG. 11A, a corner portion between the lower surface and the outer surface of the second guide protrusion 57T is cut obliquely to form an inclined surface 57F, and the inclined surface 57F according to the present invention is “ It is a “second sliding contact guide portion”.

  In addition, when a force that pushes the rotary lid 50 forward is applied in the half-closed state of the lid, the rotary lid 50 approaches the lid closing engagement portion 26 side, and the main body side hinge cylinder 20 and the lid side hinge cylinder 21 are moved. It abuts and moves to the same semi-closed front end position as the fully closed front end position in the incompletely closed state. Therefore, when the rotating lid 50 disposed at the half-closed front end position is rotated toward the fully-closed state in the half-closed state of the lid, The “third sliding contact guide portion” according to the invention is provided on the upper surface of the lid closing engagement portion 26 and on the rear surface of the rotating lid 50. Specifically, the guide slope 26A of the lid closing engagement portion 26 shown in FIG. 10A is the “third sliding contact guide portion” according to the present invention. Further, the guide inclined surface 59A of the inner side surface projection 59 in the rotary lid 50 shown in the figure is the “third sliding guide portion” according to the present invention.

  The description regarding the structure of the container 10 with a lid of this embodiment is above. Next, the effect of this lidded container 10 will be described. As shown in FIG. 2, in order to bring the lid-covered container 10 in which the rotation of the rotation lids 50 and 50 is restricted by the lid closing engagement portion 26 in the fully closed state to the fully open state, first, the rotation is performed. The lids 50 and 50 are moved to the rear side. Then, the inner surface protrusion 59 and the locking protrusion 27 shown in FIG. 10B come into contact with each other, or one side surface of the back side of the belt receiving groove 57 shown on the left side in FIG. The rotation lid 50 is positioned at the fully closed rear end position by contact with one inner side surface of 17 and the engagement with the lid closing engagement portion 26 is released, thereby enabling rotation. Then, the rotating lids 50 and 50 may be rotated in the opening direction so that the lids are fully opened depending on the hinge portions 16 and 16.

  Here, when the rotary lids 50 and 50 are arranged at the fully closed rear end position, the rotary lids 50 and 50 protrude from one end side in the longitudinal direction of the container main body 11 as shown in FIG. However, in the process of opening the rotating lid 50, the side-constituting wall 18A of the belt contact protrusion 18 and the inclined surface 57S of the belt receiving groove 57 are in sliding contact as shown in FIGS. 11 (A) to 11 (B). Thus, the rotating lid 50 is guided to the fully opened rear end position where it does not protrude from the container body 11 as shown in FIGS. Thereby, the protrusion of the rotation lid 50 in the container body 11 in the fully open state of the lid is suppressed, and the rotation lid 50 can be prevented from being damaged due to a collision with an obstacle. Specifically, when the lid-covered container 10 is fed by the belt conveyor to increase the efficiency of the luggage storage operation, the rotating lid 50 collides with an obstacle along the belt conveyor and is damaged. Can be prevented.

  When the luggage is accommodated in the containers 10 with lids, the rotary lids 50 and 50 are closed. Then, when the rotary lids 50, 50 are in the lid half-closed state, the trapezoidal protrusions 51, 51 of the rotary lids 50, 50 intersect each other. Then, when the rotating lid 50 is rotated from the lid half-closed state to the lid fully-closed state, the other rotating lid 50 is placed on the projecting piece flat plate 54 (see FIG. 7A) of the one rotating lid 50. In a state where the trapezoidal projecting pieces 51 overlap, the lid locking projections 54T are locked to the lower surface of the trapezoidal projecting pieces 51, and both the rotating lids 50, 50 are connected.

  Here, when a rearward force is applied to the rotary cover 50 in the lid half-closed state, the rotary lid 50 is arranged at the rear half-closed end position behind the fully-closed rear end position in the lid fully closed state. The However, when the rotating lid 50 is rotated as it is toward the fully closed state, the inclined surface 57F of the second guide projection 57T rides on the triangular inclined surface 17S of the side wall upper end recess 17 as shown in FIG. Then, the rotary lid 50 moves forward and is guided to the fully closed rear end position.

  On the other hand, when a forward-facing force is applied to the rotating lid 50 in the semi-closed state of the lid, the rotating lid 50 is disposed at the same semi-closed front end position as the fully closed front end position in the fully closed state of the lid. Then, when the rotating lid 50 is rotated as it is toward the fully closed state, as shown in FIG. 10A, the guide slope 26A of the lid closing engagement portion 26 and the guide slope 59A of the inner side projection 59 are obtained. The sliding lid 50 moves to the front side and is guided to the fully closed rear end position.

  That is, in the container 10 with a lid of the present embodiment, the rotating lid 50 is rotated in the closing direction regardless of whether the rotating lid 50 in the half-closed state is closer to the front side or the rear side of the linearly movable range. It can be easily moved to the fully closed rear end position in the fully closed state simply by moving. When the rotary lid 50 is moved from the fully closed rear end position to the fully closed front end position in the fully closed state, the lid closing engagement portion 26 is engaged with the rotating lid 50 and is held in the fully closed state. The Thus, according to the configuration of the present embodiment, it is possible to smoothly perform the closing rotation operation and the linear movement operation until the opened rotation lid 50 is engaged with the lid closing engagement portion 26.

  When the rotating lid 50 is engaged with the lid closing engagement portion 26, the belt 101 is wound around the entire container 10 with lid, as shown in FIG. Then, the belt 101 is settled in the belt receiving groove 57 of the rotating lid 50 and the belt engaging groove 13M of the container body 11 and is stabilized. Since the tightening force from the side by the belt 101 at this time is received by the pair of belt contact protrusions 18, 18, the load on the rotating lids 50, 50 due to the tightening of the belt 101 is reduced. Further, as shown in FIG. 1, each belt contact protrusion 18 is received by the belt receiving groove 57 of the rotation cover 50 when the cover is fully opened. The rotation range of the lid 50 is not narrowed.

  Note that there are cases where a plurality of containers 10 with lids are arranged on a pallet and transported together with the pallet in order to transport efficiently. Then, another pallet 100 may be stacked on the lidded containers 10 group as shown in FIG. In such a case, in the lidded container 10 of the present embodiment, the upper surface 56A of the load receiving portion 56 provided in the rotary lid 50 is located on the inner upper side with respect to the hinge portion 16 and is the most in the lidded container 10. Since it is arranged at a high position, the pallet 100 stacked above does not contact the hinge portion 16. In addition, since the lower surface 56B that comes into contact with the upper end portion of the first side wall 13 is provided vertically below the upper surface 56A of the loading load receiving portion 56, the load received from the upper side is not passed through the hinge portion 16. 1 side wall 13 can be transmitted. Thereby, the load of the pallet 100 piled up on does not apply to the hinge part 16, and damage to the hinge part 16 is prevented. Moreover, since the load receiving part 56 has a shape extending along the upper end of each first side wall 13, the loads received by the load receiving part 56 and the first side wall 13 are dispersed, and these load Damage to the receiving portion 56 and the first side wall 13 is also prevented.
