Further, as shown in FIG. 6, on the upper surface of the rear portion of the second lid 30, there is a locking claw accommodating recess for accommodating each locking claw 44 between each arc portion 37h and each short straight portion 37i. 34 are formed respectively. Each locking claw 44 is accommodated in each locking claw accommodating recess 34 when the door 40 is closed until the base thereof is bent. Further, between the short straight portions 37i, an operation portion accommodating recess 33 for accommodating the operation portion 43 when the door 40 is closed is formed. The bottom wall of the operation unit accommodating recess 33 is flush with the top 32c.
The pair of locking claws 44 are formed so as to project rearward from the outer portion of each locking protrusion 46 of the rear end wall 42d of the door 40. Retaining pieces 44a are formed on the left and right side surfaces of the locking claws 44, respectively. Each of the locking claws 44 is formed so as to be bendable downward from the base portion, and by bending downward, the tip of each retaining piece 44a is formed so as to face upward.

Each locking claw accommodating recess 34 is formed with a locking claw insertion hole 34a for inserting and locking each locking claw 44 bent downward. Each downwardly bent locking claw 44 is inserted into each corresponding locking claw insertion hole 34a. Each retaining piece 44a of each locking claw 44 is elastically deformed and folded when passing through the locking claw insertion hole 34a, and each tip of each retaining piece 44a is in a locked claw insertion hole 34a. When it escapes downward from, it returns to its original expanded state due to its own elastic force. As a result, each locking claw 44 is locked in each locking claw insertion hole 34a and cannot be pulled out upward. That is, the opening of the door 40 due to vibration or the like when the second container with a lid 2 is transported is prevented, and the contained injection needle or the like is prevented from popping out or leaking.

Further, the operation unit 43 housed in the operation unit accommodating recess 33 is in a floating state from the bottom wall of the operation unit accommodating recess 33, and a finger can be easily hooked when opening the door 40. There is. Further, as shown in FIG. 3, the second container with a lid 2 has a structure in which the opened door 40 is supported by the upper surface 31a (FIG. 2) of the upper wall 31. At this time, the operation portion 43 of the door 40 and each locking claw 44 fit into the operation recess 36 (FIG. 2). Further, since the operation unit 43 is housed in a state of floating from the bottom wall of the operation recess 36, it is possible to easily put a finger on the operation unit 43 when closing the door 40.

As shown in FIG. 12, the lid peripheral wall 32 of the second lid 30 includes the above-mentioned top portion 32c, the lid first side wall 32a, the lid second side wall 32e, the locking portion 32f, and the inner side wall 32b. It is provided with a fitting groove 32d. The first side wall 32a of the lid extends downward from the outer peripheral edge of the top 32c and is formed over the entire outer peripheral edge of the top 32c. The second side wall 32e of the lid is formed in a flange shape that projects outward from the lower edge of the first side wall 32a of the lid and bends downward from the middle. The second side wall 32e of the lid is formed over the entire lower edge of the first side wall 32a of the lid. The inner wall surface of the second side wall 32e of the lid is formed in a shape that substantially matches the outer wall surface of the peripheral wall flange 17 of the container body 10.

The locking portion 32f is formed so as to project inward from the inner wall of the second side wall 32e of the lid, and is formed over the entire inner wall of the second side wall 32e of the lid. The inner side wall 32b is formed so as to project downward from the lower surface of the top portion 32c, and is formed over the entire circumference of the lower surface of the top portion 32c. The fitting groove 32d is formed between the inner side wall 32b and the first side wall 32a of the lid, and is formed over the entire circumference between the inner side wall 32b and the first side wall 32a of the lid.
The fitting groove 32d is formed so that the upper end 14c (FIG. 4) of the peripheral wall 14 of the container body 10 can be fitted. The opposing inner walls of the fitting groove 32d come into contact with each other at predetermined locations. When the upper end 14c is fitted into the fitting groove 32d, the second side wall 32e of the lid covers the peripheral wall flange 17, and the second side wall 32e of the lid and the peripheral wall flange 17 come into contact with each other at predetermined positions. Further, the locking portion 32f is locked to the lower end 17a of the peripheral wall flange 17. As a result, the second side wall 32e of the lid covers the peripheral wall flange 17, the locked state is maintained, and the second lid 30 does not easily come off from the container body 10. The second side wall 32e of the lid may be formed so as to be in close contact with the peripheral wall flange 17, so that the airtightness can be further improved.

The mounting structure for mounting the second lid 30 to the container body 10 is composed of an inner side wall 32b, a lid first side wall 32a, and a fitting groove 32d. The inner side wall 32b and the lid first side wall 32a forming the fitting groove 32d form the inner side wall 22d and the lid first side wall 22a forming the fitting groove 22g in the first lid 20 of the first lid-attached container 1 (FIG. It is the same as 11).
That is, the mounting structure for mounting the second lid 30 on the container body 10 is the same as the mounting structure for mounting the first lid 20 on the container body 10. Further, each mounting structure is provided on each lower surface of the first lid 20 and the second lid 30, respectively.
As described above, since the first lid 20 and the second lid 30 each have a common mounting structure for mounting in the opening 14d of the container body 10, the first lid 20 or the second lid 30 is used as a container. Workability when attaching to the opening 14d of the main body 10 can be improved.
Further, since both the first lid 20 and the second lid 30 having different shapes can be attached to the opening 14d of the container body 10, the container body 10 can be shared, so that the first one can be used. It is also possible to reduce the manufacturing cost of the container 1 with a lid and the container 2 with a second lid.

As shown in FIG. 12, a straight portion 37f forming the convex portion 37 is formed so as to project upward inside the top portion 32c. The outer wall 37a forming the straight portion 37f is formed so as to rise from the peripheral edge of the top portion 32c, and the upper wall 37c is continuously formed substantially horizontally from the upper edge of the outer wall 37a toward the inside. An inner wall 37b is formed so as to fall from the inner peripheral edge of the upper wall 37c, and a wall 37d is formed substantially horizontally inward from the lower edge of the inner wall 37b. Further, from the inner peripheral edge of the wall 37d, the wall 37e is formed substantially vertically downward. The door convex wall 42 has an inner wall 42b formed so as to rise from the bottom wall 41a of the door recess 41, an upper wall 42c formed substantially horizontally from the upper end of the inner wall 42b, and an outer end of the upper wall 42c. It has a side wall 42a formed by falling from the side wall 42a. The wall 37d and the inner wall 37b form the periphery of the lid opening 31c. The side wall 42a of the door convex wall 42 and the inner wall 37b of the straight portion 37f face each other at positions close to each other. Further, as shown by reference numeral E3 in FIG. 12, the lower surface of the boundary portion between the lower end of the inner wall 42b of the door convex wall 42 and the bottom wall 41a of the door recess 41 is in contact with the upper surface of the wall 37d. That is, the lid opening 31c is sealed by the door 40.

Further, as indicated by reference numeral E4, the lower end of the side wall 42a of the door convex wall 42 is in contact with the upper surface of the wall 37d. That is, the door 40 has a double structure in which the door 40 is in contact with each other at two locations on the upper surface of the wall 37d. In other words, when the lid opening 31c is closed by the door 40, the portion where the door 40 and the peripheral edge of the lid opening 31c come into mutual contact has a double structure. Therefore, for example, even if the contained object leaks from the lid opening 31c, the leakage can be prevented at the portion (E4) where the side wall 42a of the door 40 and the wall 37d are in contact with each other. As shown in FIG. 6, the wall 37d is also formed in a region extending from one arc portion 37h to the other arc portion. That is, the second lid 30 is configured to effectively prevent the leakage of contained matter in the entire region where the door convex wall 42 abuts when the door 40 is closed. Further, as shown in FIG. 12, by fitting the upper end 14c of the peripheral wall 14 of the container body 10 into the fitting groove 32d, leakage of the contained material in a region other than the lid opening 31c is prevented.

In particular, when the second lidded container 2 is used for accommodating a used injection needle, the tip of the contained injection needle does not pop out, so that the second lidded container 2 is transported. There is no risk of the operator being injured by the injection needle. That is, it is possible to provide a highly safe container with a lid.
Further, the operation recess 36 projects downward from the lower surface 31b of the upper wall 31, but the lowermost surface thereof does not exceed the lower edge of the second side wall 32e of the lid. That is, the second lid 30 is devised so that the capacity of the container body 10 that can be accommodated is not reduced as much as possible.
The lid peripheral wall 32, the convex portion 37, and the upper wall 31 constituting the second lid 30 are integrally formed. In this embodiment, the second lid 30 and the door 40 are each formed by injection molding using a synthetic resin such as polypropylene as a raw material.
As shown in FIG. 8, in the first lidded container 1 and the second lidded container 2, the lid of the lidded container arranged on the upper side and the lid of the lidded container arranged on the lower side are the first, respectively. Both the first lid 20 and the second lid 30 are configured to be vertically stackable. Therefore, the work efficiency of stacking can be improved.

[Regulatory structure]
The container with a lid placed on the upper side and the container with a lid placed on the lower side restrict the horizontal movement of the container with a lid placed on the upper side during transportation of the container with a lid arranged vertically. It has a regulatory structure to do so. The regulatory structure will be explained with reference to the figure.

(When the second container 2 with a lid is stacked on the first container 1 with a lid)
As shown in FIGS. 9 and 11, the second container with a lid 2 is stacked on the first container with a lid 1. A first lid 20 is attached to the first lidded container 1 arranged on the lower side, and a second arranged on the upper side inside the recessed side wall 22b constituting the first lid 20. A rib 13 projecting downward from the bottom wall 11 of the container 2 with a lid is arranged. The lower end 13c of the rib 13 is in contact with the upper surface of the bottom wall 21a of the recess 21. The outer surface 13a of the rib 13 and the inner surface 22e of the recessed side wall 22b are in close proximity to each other, and when the second container with a lid 2 arranged on the upper side moves to the right during transportation, the outer surface 13a of the rib 13 Is in contact with the inner surface 22e of the recessed side wall 22b, so that the movement of the second container with a lid 2 arranged on the upper side to the right is restricted. Further, when the second container with a lid 2 arranged on the upper side moves to the left during transportation, the outer surface 13a of the rib 13 (FIG. 9) located on the left abuts on the inner surface 22e of the recessed side wall 22b. Therefore, the movement of the second container with a lid 2 arranged on the upper side to the left is restricted.
Therefore, the horizontal movement of the second lidded container 2 arranged on the upper side when the second lidded container 2 is transported in a stacked state on the first lidded container 1 is restricted. Therefore, stable transportation can be performed.

Further, since the container body 10 of the first lidded container 1 and the second lidded container 2 is common, even when the first lidded container 1 is stacked on top of the first lidded container 1. Since the rib 13 of the first lidded container 1 arranged on the upper side is arranged inside the recessed side wall 22b of the first lidded container 1 arranged on the lower side, the first one arranged on the upper side. The horizontal movement of the container 1 with a lid can be restricted.
Therefore, the horizontal movement of the first lidded container 1 arranged on the upper side when the first lidded container 1 is transported in a stacked state on the first lidded container 1 is restricted. Therefore, stable transportation can be performed.
Further, the outer surface 13a of the rib 13 and the inner surface 22e of the recessed side wall 22b are in close proximity to each other, but a gap is formed and they are not in contact with each other. This is to facilitate stacking of the second container 2 with a lid on the first container 1 with a lid. That is, when the container with a lid is configured so as to eliminate the above-mentioned gap, the lower end 13c of the rib 13 of the second container with a lid 2 arranged on the upper side and the concave portion of the first container with a lid 1 arranged on the lower side. This is because the inner surface 22e of the side wall 22b easily collides with the inner surface 22e, and it becomes difficult to stack the second lidded container 2 on the first lidded container 1.

(When the first container 1 with a lid is stacked on the second container 2 with a lid)
As shown in FIGS. 10 and 12, the first container with a lid 1 is stacked on the second container with a lid 2. A second lid 30 is attached to the second lidded container 2 arranged on the lower side, and a first arranged on the upper side is provided on the outside of the outer wall 37a constituting the second lid 30. A rib 13 projecting downward from the bottom wall 11 of the container 1 with a lid is arranged. The lower end 13c of the rib 13 is in contact with the upper end of the top 32c. The inner surface 13b and the outer wall 37a of the rib 13 are in close proximity to each other, and when the first container with a lid 1 arranged on the upper side moves to the left during transportation, the inner surface 13b of the rib 13 becomes the outer wall 37a. Since it abuts on the outer surface, the movement of the first container with a lid 1 arranged on the upper side to the left is restricted. Further, when the first container with a lid 1 arranged on the upper side moves to the right during transportation, the inner surface 13b of the rib 13 (FIG. 10) located on the left side abuts on the outer surface of the outer wall 37a. The movement of the first container with a lid 1 arranged on the upper side to the right is restricted.
Therefore, the horizontal movement of the first lidded container 1 arranged on the upper side when the first lidded container 1 is transported in a stacked state on the second lidded container 2 is restricted. Therefore, stable transportation can be performed.

Further, since the container body 10 of the first lidded container 1 and the second lidded container 2 is common, even when the second lidded container 2 is stacked on top of the second lidded container 2. , Since the rib 13 of the second lidded container 2 arranged on the upper side is arranged outside the outer wall 37a of the second lidded container 2 arranged on the lower side, the second lid arranged on the upper side. The horizontal movement of the attached container 2 can be regulated.
Therefore, the horizontal movement of the second lidded container 2 arranged on the upper side when the second lidded container 2 is transported in a stacked state on the second lidded container 2 is restricted. Therefore, stable transportation can be performed.
Further, the inner surface 13b of the rib 13 and the outer surface of the outer wall 37a are in a state of being close to each other, but a gap is formed and they are not in a state of being in contact with each other. This is to facilitate stacking of the first container 1 with a lid on the second container 2 with a lid. That is, when the container with a lid is configured so as to eliminate the above-mentioned gap, the lower end 13c of the rib 13 of the first container with a lid 1 arranged on the upper side and the outer wall of the second container with a lid 2 arranged on the lower side are formed. This is because the outer surface of 37a is likely to collide with each other, and it becomes difficult to stack the first container with a lid 1 on the second container with a lid 2.

As described above, the regulation structure for restricting the horizontal movement of the container with the lid arranged on the upper side is the rib 13 protruding downward from the bottom wall 11 of the container body 10 and the top of the first lid 20. It is composed of a concave portion 21 recessed downward from 22c and a convex portion 37 protruding upward from the top 32c of the second lid 30. Then, in the first lid-covered container 1 and the second lid-covered container 2, when the lid of the lid-covered container arranged on the lower side is the first lid 20, the rib of the lid-covered container arranged on the upper side is used. 13 is arranged inside the recess 21 recessed downward from the top 22c of the first lid 20, and when the lid of the container with a lid arranged on the lower side is the second lid 30, it is on the upper side. The rib 13 of the container with a lid to be arranged has a structure to be arranged outside the convex portion 37 protruding upward from the top portion 32c of the second lid 30.

Further, as shown in FIG. 12, the upper wall 37c constituting the second lidded container 2 arranged on the lower side is in a state of being close to the bottom wall 11 of the first lidded container 1 arranged on the upper side. Although the upper wall 37c is not configured to support the bottom wall 11, it may be configured to support the bottom wall 11. If this configuration is implemented, the area for supporting the first lidded container 1 or the second lidded container 2 arranged on the upper side becomes large, so that the first lidded container 1 or the first lidded container 1 or the second arranged on the upper side becomes large. The container 2 with a lid of 2 can be supported more stably.
Further, the upper wall 42c of the door convex wall 42 constituting the door of the second lidded container 2 arranged on the lower side is the first lidded container 1 or the second lidded container arranged on the upper side. It can also be configured to support the bottom wall 11 of 2. If this configuration is implemented, the area for supporting the first lidded container 1 or the second lidded container 2 arranged on the upper side becomes even larger, so that the first lidded container 1 arranged on the upper side Alternatively, the second container with a lid 2 can be supported more stably.

Further, since the upper wall 42c of the door convex wall 42 constituting the door of the second lidded container 2 arranged on the lower side does not exceed the upper wall 37c of the straight portion 37f, the first arranged on the upper side. Since the bottom wall 11 of the container 1 with a lid does not float from the upper wall 37c of the straight portion 37f and the lower end 13c of the rib 13 does not float from the top 32c, the first container with a lid 1 arranged on the upper side does not float. Alternatively, the second container with a lid 2 can be stably supported. Further, since the door 40 is provided between the pair of straight portions 37f included in the convex portion 37, the rib 13 protruding from the bottom wall 11 of the container with the lid arranged on the upper side does not interfere with the door 40. Since the rib 13 can be arranged on the outside of the convex portion 37, the horizontal movement of the container with the lid arranged on the upper side can be reliably regulated.
