Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, once the insertion opening of the container of Patent Document 1 is closed by the door member, the locking portion provided on the lid body is locked to the back surface side of the lid main body to be in a sealed state, and it is basically configured to be impossible (difficult) to open. For this reason, there may be a need to discard the container as it is because the door member is accidentally closed when there is a margin in the storage space of the container, or there may be a need to carefully break and open the container without touching the contents in order to search including the storage space of the container after sealing. There is concern that the convenience regarding the opening and closing of the door member is low.

[0005] The present invention has been made to solve the above-exemplified problems and the like, and an object thereof is to provide a container capable of improving the convenience regarding the opening and closing of the door member.

Means for Solving the Problems

[0006] The following sections will describe each means suitable for achieving the above objectives. Additionally, specific effects and benefits of each means will be noted as needed.

[0007] Means 1. A container body having a roughly box-like shape with an opening at the top and a storage section capable of accommodating articles, and a lid that can close the opening of the container body, The container comprises a lid body made of synthetic resin that is attached to the container body and has an opening into which an article can be inserted, and a door member made of synthetic resin that is displaceable between an open position that opens the opening and a closed position that closes the opening, The door member comprises an operating part that is operated when the door member is displaced, and a first locking part that is locked to a first locking part provided on the lid body when the door member is in the closed position. The door member is provided with temporary holding means that allows it to be held in a temporarily closed position between the open position and the closed position. 、 The temporary holding means is, The second locking portion provided on the door member, A temporary locking portion is provided on the lid body or the door member, which restricts the displacement of the door member in the temporarily closed position toward the closed position, The lid body is provided with a second locking portion which contacts the second locking portion of the door member in the temporarily closed position to restrict the displacement of the door member toward the open position, When the door member is moved from the open position to the temporarily closed position, the second locking portion is configured to slide against the second locked portion from its position on the inside of the lid body, and to be displaceable toward the input opening side of the second locked portion. A container characterized by the following features.

[0008] According to means 1, the door member is configured to be held in a temporarily closed position, which is a position between the open position and the closed position. As a result, although the door member has not yet been moved to the closed position, the door member can be kept in the temporarily closed position except when, for example, an item is being placed into the container, thereby minimizing the separation between the container's contents and the outside of the container, and minimizing contact between the environment of the container's contents and the environment outside the container. Therefore, it is possible to improve convenience in situations where it is undesirable for the environment of the container's contents to affect the outside of the container (for example, for a person to come into contact with an item contained in the container), or for the environment outside the container to affect the container's contents (for example, for unwanted items such as garbage or various tools to enter the container).

[0010] Also, The second locking part and the temporary locking part restrict the displacement of the door member in the temporarily closed position toward the closed position, and also restrict the displacement of the door member in the closed position toward the open position. Therefore, while suppressing the complexity of the structure, it is possible to more reliably prevent the displacement of the door member in the closed position toward the open position.

[0012] Also, When the second locking part is released from a state in which it is slidingly in contact with the second locked part, the user can perceive that the door member has been placed in the temporarily closed position by feel (click sensation). Therefore, it is possible to prevent the door member from being accidentally moved to the closed position when it was intended to be moved from the open position to the temporarily closed position.

[0013] means 2 . It comprises a container body that is roughly box-shaped with an opening at the top and has a storage section capable of accommodating articles, and a lid that can close the opening of the container body. The container comprises a lid body made of synthetic resin that is attached to the container body and has an opening into which an article can be inserted, and a door member made of synthetic resin that is displaceable between an open position that opens the opening and a closed position that closes the opening, The door member comprises an operating part that is operated when the door member is displaced, and a first locking part that is locked to a first locking part provided on the lid body when the door member is in the closed position. The door member is provided with a temporary holding means that allows it to be held in a temporarily closed position between the open position and the closed position. The temporary holding means is, The second locking portion provided on the door member, A temporary locking portion is provided on the lid body or the door member, which restricts the displacement of the door member in the temporarily closed position toward the closed position, The lid body is provided with a second locking portion which contacts the second locking portion of the door member in the temporarily closed position to restrict the displacement of the door member toward the open position, The door member is characterized by having a restricting portion that, when in the open position, contacts the temporary locking portion to restrict the displacement of the door member toward the closed position. content vessel.

[0014] means 2According to this, since it is possible to hold the open state in which the door member is in the open position, for example, it is possible to prevent a situation in which the door member is displaced unintentionally to the closed position side when an article is stored in the storage portion of the container. In addition, with the configuration that holds the open state using the temporary locking portion, it is possible to suppress the complication of the configuration, and due to the complication of the configuration, the opening and closing operability of the door member is reduced, dust and the like are likely to accumulate, or the design property is reduced, etc. It is possible to suppress situations.

[0015] Means 3 . It comprises a container body that is roughly box-shaped with an opening at the top and has a storage section capable of accommodating articles, and a lid that can close the opening of the container body. The container comprises a lid body made of synthetic resin that is attached to the container body and has an opening into which an article can be inserted, and a door member made of synthetic resin that is displaceable between an open position that opens the opening and a closed position that closes the opening, The door member comprises an operating part that is operated when the door member is displaced, and a first locking part that is locked to a first locking part provided on the lid body when the door member is in the closed position. The door member is provided with a temporary holding means that allows it to be held in a temporarily closed position between the open position and the closed position. The door member includes a closing portion that closes the charging opening when the door member is in the closed position, and a cover portion that protrudes from the leading edge of the closing portion on the side of the door member toward the closed position when the door member moves from the open position to the closed position. The lid body is provided with a lid cover portion that overlaps the cover portion in the inner and outer directions of the container in a state where the door member is in the temporarily closed position, and increases the overlapping area in the closed state. content Container.

[0016] Means 3 According to this, in a state where the door member is in the temporarily closed position, the closing portion does not completely close the charging opening, but the cover portion located on the closed position side of the door member with respect to the closing portion and the lid cover portion are provided. Even when the door member is in the temporarily closed position, the charging opening can be made in a substantially closed state. Therefore, except when an article is put into the container, the door member is set to the temporarily closed position, and the environment between the storage portion of the container and the outside of the container is shielded as much as possible, and the environment of the storage portion of the container and the outside environment of the container are prevented from intersecting as much as possible. The effect of suppressing this is further enhanced.

[0017] Means 4 . It comprises a container body that is roughly box-shaped with an opening at the top and has a storage section capable of accommodating articles, and a lid that can close the opening of the container body. The container comprises a lid body made of synthetic resin that is attached to the container body and has an opening into which an article can be inserted, and a door member made of synthetic resin that is displaceable between an open position that opens the opening and a closed position that closes the opening, The door member comprises an operating part that is operated when the door member is displaced, and a first locking part that is locked to a first locking part provided on the lid body when the door member is in the closed position. The door member is provided with a temporary holding means that allows it to be held in a temporarily closed position between the open position and the closed position. The door member is provided with a placement portion on the inside of the lid that allows an article to be placed when the door member is in the open position. The door member, which is in the open position, is displaced toward the closed position, causing the article placed on the aforementioned storage area to fall into the storage area of ​​the container body. The lid body is characterized by having an inclined portion that can guide an item that has fallen from the aforementioned resting portion toward the inside of the container. content vessel.

[0018] means 4 According to the invention, the door member having a support section helps to suppress variations in the orientation and falling speed of items placed (put into) the container. Furthermore, the inclined section of the lid body prevents items from piling up in one place in the container's storage area in a position that would obstruct the opening and closing of the door member. Therefore, items can be efficiently placed into the container without the need for special work by the worker (for example, leveling the items placed in the container).

[0019] means 5 . It comprises a container body that is roughly box-shaped with an opening at the top and has a storage section capable of accommodating articles, and a lid that can close the opening of the container body. The container comprises a lid body made of synthetic resin that is attached to the container body and has an opening into which an article can be inserted, and a door member made of synthetic resin that is displaceable between an open position that opens the opening and a closed position that closes the opening, The door member comprises an operating part that is operated when the door member is displaced, and a first locking part that is locked to a first locking part provided on the lid body when the door member is in the closed position.

[0023] An embodiment will be described below with reference to the drawings. As shown in Figures 1 and 2, the container 1 is a roughly rectangular box shape with an opening at the top and comprises a container body 2 having a storage section 3 inside that can accommodate articles (for example, used syringes, etc.) and a lid 4 that can close the opening of the container body 2. The lid 4 is attached to the container body 2 and comprises a lid body 5 having an input opening 6 into which articles can be inserted, and a door member 7 that can be displaced between an open position that opens the input opening 6 and a closed position that closes it.

[0024] As shown in Figure 2, the container body 2 comprises a bottom wall component 11 which is roughly rectangular in plan view, a pair of opposing long side wall components 12 which extend upward from a pair of opposing long sides of the bottom wall component 11, a pair of opposing short side wall components 13 which extend upward from a pair of opposing short sides of the bottom wall component 11, a roughly square frame-shaped overhang 14 which protrudes outward from the entire upper surface of the long side wall components 12 and the short side wall components 13, and an edge wall component 15 which protrudes downward from the entire outer surface of the overhang 14. The container body 2 is configured in a tapered shape in which the long side wall components 12 and the short side wall components 13 are slightly inclined outward from the container body 2 towards the top. Furthermore, as shown in Figure 4, the container body 2 includes an upper frame reinforcing portion 16 that connects the edge wall portion 15, the overhang portion 14, and the long side wall portion 12 or the short side wall portion 13. The container body 2 in this embodiment is integrally formed from polypropylene.

[0025] In addition, as shown in Figure 2, the bottom wall component 11 is provided with a bottom inclined portion 17 that slopes downward toward the other long side wall component 12 from the connection point with one of the pair of long side side wall components 12. The bottom inclined portion 17 is provided at a position spaced apart from each short side wall component 13, and the portion of the bottom wall component 11 between the bottom inclined portion 17 and each short side wall component 13 extends in the horizontal direction. Furthermore, the long side wall component 12 connected to the upper edge of the bottom inclined portion 17 has a shape in which the portion directly below the portion connected to the bottom inclined portion 17 is notched.

[0026] As shown in Figures 2 to 4, the lid body 5 comprises a substantially rectangular frame-shaped flange portion 21 that rests on the protruding portion 14 of the container body 2 when attached to the container body 2, long-side vertical wall portions 22 extending upward from the inner edges of a pair of opposing long sides of the flange portion 21, short-side vertical wall portions 23 extending upward from the inner edges of a pair of opposing short sides of the flange portion 21, a top wall component portion 24 connecting the upper edges of the long-side vertical wall portions 22 and the short-side vertical wall portions 23, and a covering portion 25 that protrudes downward from the entire outer edge of the flange portion 21 and covers the edge wall portion 15 of the container body 2 from the outside of the container 1 when attached to the container body 2. Furthermore, the lid body 5 includes mounting claws 26 that protrude from the entire lower edge of the covering portion 25 towards the inner circumference of the covering portion 25, and an inner frame portion 27 that protrudes downward from the lower surface of the flange portion 21 along the entire circumference of the flange portion 21 and faces the inner surfaces of the long side wall portion 12 and the short side wall portion 13 of the container body 2 when the lid body 5 is attached to the container body 2.

[0027] As shown in Figure 4, when the lid body 5 (lid 4) is attached to the container body 2, the portion between the edge wall portion 15 of the container body 2 and the long side wall portion 12 and the short side wall portion 13 is inserted between the covering portion 25 and the inner frame portion 27 of the lid body 5, and the mounting claw portion 26 is locked to the lower edge of the edge wall portion 15 of the container body 2. As a result, it is basically difficult (or impossible) to remove the lid body 4 from the container body 2. The lower edge of the inner frame portion 27 is located above the lower edge of the covering portion 25. In addition, the lid body 5 in this embodiment is integrally formed from polypropylene. Furthermore, regarding the mounting claw portion 26, it is also possible to provide it partially in the circumferential direction of the covering portion 25 (for example, providing it in multiple places on each side of the covering portion 25).

[0028] Furthermore, as shown in Figures 2 and 3, the lid body 5 is configured to have an R-shape, which is roughly a semi-circular arc extending from a position slightly above the lower edge of one of the long side vertical wall portions 22 to the top wall component 24. The input opening 6 is provided in this R-shaped portion, with the rest of the opening being open while leaving a small portion of both sides intact. In addition, a roughly U-shaped handle 28 is rotatably connected to the upper surface of the top wall component 24. The handle 28 is configured to be displaceable between a reclining position where it is housed in a concave handle housing portion 29 provided in the top wall component 24, and an upright position where it protrudes above the upper end of the top wall component 24.

[0029] As shown in Figures 5 to 7, the door member 7 comprises a pair of opposing side plate portions 31 that are roughly semicircular in shape, a closing portion 32 with a roughly arc-shaped cross-section that connects the arc-shaped portions of the pair of side plate portions 31, a back plate portion 33 that connects the straight portions of one of the pair of side plate portions 31, and a shaft portion 34 that protrudes laterally from the door member 7 from a position approximately at the center of the arc of each side plate portion 31. The peripheral portion of the shaft portion 34 of the side plate portion 31 is stepped in such a way that the base of the shaft portion 34 protrudes slightly laterally than the side plate portion 31. Furthermore, the door member 7 of this embodiment is integrally formed from polypropylene.

[0030] On the other hand, as shown in Figures 1 and 2, the lid body 5 is provided with pivot supports 35 on each short-side vertical wall 23 that allow each shaft portion 34 of the door member 7 to rotate and displace. The distance between the outer surfaces of the pair of side plate portions 31 of the door member 7 is slightly shorter than the distance between the inner surfaces of the pair of short-side vertical wall portions 23 of the lid body 5. By inserting the shaft portion 34 of the door member 7 into the pivot supports 35 of the lid body 5, the door member 7 is connected to the lid body 5 in a way that allows it to rotate and displace. As shown in Figures 2 and 3, the pivot supports 35 are formed by providing a circular through hole in the short-side vertical wall 23 and slightly bulging the lower part of the through hole outwards, with the lower side of the shaft portion 34 supported by the arc-shaped upper edge of the bulging portion (a groove-shaped portion is formed on the inside of the lid body 5 at the bulging portion, and the door member 7 is connected to the lid body 5 from the lower inner side of the lid body 5).

[0031] Furthermore, the arc shape of the side plate portion 31 of the door member 7 corresponds to the R-shaped portion of the lid body 5. As shown in Figure 1 and other figures, when the door member 7 is connected to the lid body 5, both sides of the closing portion 32 are positioned in close proximity to (or in contact with) the inner surfaces (back surfaces) of the R-shaped portions on both sides of the input opening 6, and the closing portion 32 is configured to be able to close the entire input opening 6. In this embodiment, the position (posture) of the door member 7 in which the input opening 6 is closed by the closing portion 32, as shown in Figures 1 and 8, corresponds to the closed position, and the state in which the door member 7 is in the closed position corresponds to the closed state of the container 1.

[0032] Furthermore, as shown in Figure 5 and other figures, the door member 7 is provided with a restricting portion 36 that protrudes outward from the edge of the closing portion 32 on the side not connected to the back plate portion 33. As shown in Figure 1 and other figures, when the door member 7 is connected to the lid body 5, the restricting portion 36 protrudes through the input opening 6 to the outside of the lid body 5, and as shown in Figures 8 and 10, when the door member 7 is in the closed position, the lower surface of the restricting portion 36 abuts against and is supported by the lower edge of the input opening 6 (further rotational displacement is restricted).

[0033] As shown in Figures 5 and 8, the restricting portion 36 of this embodiment is provided in the direction of the rotation axis (width direction) of the door member 7, including the vicinity of both ends of the closing portion 32 (positions that do not interfere with the R-shaped portion of the lid body 5), but not in the area including the central part of the closing portion 32. Instead, an operating portion 37 is provided that protrudes outward from the door member 7 from a position on the edge side of the closing portion 32 that is connected to the back plate portion 33, rather than the edge where the restricting portion 36 is provided. Both sides of the operating portion 37 are connected to the sides of the restricting portion 36, and when the door member 7 is in the closed position, the front edge of the operating portion 37 is located in front of the front edge of the container 1, with the front of the container 1 being the surface visible when viewing the long side vertical wall portion 22 where the input opening 6 is formed (see Figures 8 to 10).

[0034] As shown in Figure 14, the door member 7 is opened by rotating it approximately 90 degrees from the closed position, bringing the restricting portion 36 closer to the upper edge of the input opening 6. When the door member 7 is in the open position (the container 1 is open), the portion of the closing portion 32 that is located on the back plate portion 33 side of the restricting portion 36 and the operating portion 37 is housed inside the container 1 (lid body 5), and most of the input opening 6 (almost the entirety) is opened. Furthermore, by placing a fingertip on the underside of the operating portion 37 relative to the door member 7 in the closed position, the door member 7 can be displaced to the open position relatively easily.

[0035] As shown in Figures 2 and 3, the top wall component 24 of the lid body 5 constitutes the upper edge of the input opening 6 and is equipped with an upper edge defining portion 38 that extends in the vertical direction. Furthermore, as shown in Figures 2 and 14, the upper edge defining portion 38 is equipped with an operation housing recess 39 that accommodates the operation portion 37 of the door member 7 when the door member 7 is in the open position. This allows the restricting portion 36 to come into contact with the upper edge of the input opening 6 (upper edge defining portion 38) (see Figure 6), and the contact of the restricting portion 36 with the upper edge defining portion 38 restricts further rotational displacement of the door member 7.

[0036] As shown in Figures 14 and 15, the top wall component 24 of the lid body 5 is provided with an operation-allowing recess 40 that reduces the height of the portion of the upper edge defining portion 38 that includes the lateral center of the operation-receiving recess 39. This makes it possible to displace the door member 7 to the closed position (close the operation-receiving recess 37) by placing a finger on the rear side of the operation-receiving recess 37 of the operation-receiving recess 39 via the operation-allowing recess 40 (grabbing the operation-receiving recess 37). Furthermore, as shown in Figure 8, when the door member 7 is in the closed position, the closing portion 32 is extended toward the operation-receiving recess 39 so that the portion of the input opening 6 corresponding to the operation-receiving recess 39 can also be closed by the closing portion 32 (see Figure 6).

[0037] Now, as shown in Figures 2 and 3, the lid body 5 has a locking projection 41 that protrudes downward from the center in the lateral direction of the operation housing recess 39 within the upper edge defining portion 38. In contrast, as shown in Figures 6 and 9, the door member 7 has an insertion recess 42 into which the locking projection 41 is inserted when the door member 7 is in the closed position, and a locking projection 43 adjacent to the insertion recess 42 that protrudes outward (upward) from the closing portion 32 of the door member 7. As shown in Figures 8 and 9, when the door member 7 is in the closed position, the portion of the insertion recess 42 that is continuous with the locking projection 43, and the rear side surface of the locking projection 43 on the container 1, are in substantially contact with the portion of the upper edge defining portion 38 (operation housing recess 39) that is continuous with the locking projection 41, and the front side surface of the locking projection 41 on the container 1, thereby creating a locked state. Hereinafter, the locking projection 43 and the portion of the insertion recess 42 that is continuous with the locking projection 43 will be collectively referred to as the "first locking portion 44," and the locked projection 41 and the portion of the upper edge defining portion 38 that is continuous with the locked projection 41 will be collectively referred to as the "first locked portion 45."

[0038] In this embodiment, even if the operating part 37 of the door member 7, which is in the closed position, is operated to displace the door member 7 towards the open position, the locking state between the first locking part 44 and the first locked part 45 is relatively strong (the overlapping area in the rotational displacement direction of the door member 7, i.e., the engagement allowance is relatively large), so basically, the door member 7 cannot be displaced towards the open position. However, as shown in Figure 8, by pressing the part of the closing part 32 of the door member 7 that is slightly displaced from the first locking part 44 toward the central part of the closing part 32 (hereinafter referred to as the "release operation part 46") toward the inward (downward) side of the container 1, the area around that part deforms so that it bends toward the inward side of the container 1. Furthermore, based on this deformation, the first locking portion 44 is displaced inward from the container 1 (or the first locking portion 44 is displaced to tilt forward from the container 1), and by operating the operating unit 37 while maintaining this displaced state (operating the release operating unit 46 and the operating unit 37 simultaneously), it is possible to release the locking state between the first locking portion 44 and the first locked portion 45 and displace the door member 7 to the open position. As shown in Figure 9, the locking projection 43 has a rounded chamfer shape at the front corner of the container 1 when the door member 7 is in the closed position, while the rear corner of the container 1 does not have a chamfered shape.

[0039] Furthermore, although the release operation unit 46 and the operation unit 37 are spaced apart from each other, they are positioned so that an operator can operate both the release operation unit 46 and the operation unit 37 simultaneously with one hand. In this embodiment, the container 1 is not provided with any markings indicating the release operation unit 46 or any indication of how to operate the release operation unit 46, so that only an operator who is already familiar with how to operate the release operation unit 46 can open the container 1 from its closed state.

[0040] As shown in Figure 11, in this embodiment, the door member 7 is configured to be held in a temporarily closed position between the open position and the closed position. Specifically, the lid body 5 is provided with a temporary locking portion 47 that protrudes inward from the vicinity of the upper edge defining portion 38 on one side edge of the input opening 6 (in this example, the right side edge when viewed from the front) (see Figures 2 and 3).

[0041] In contrast, as shown in Figure 5, the door member 7 is provided with a second locking portion 49 that protrudes outward from a portion near the back plate portion 33 on one side (the right side in this example) of the closing portion 32. As shown in Figure 9, the second locking portion 49 is located in front of the container 1 when the door member 7 is in the closed position, and as shown in Figure 13, it is located behind the container 1 (inside the container 1) when the door member 7 is in the open position, beyond the portion of the upper edge defining portion 38 that is lateral to the operation receiving recess 39 (hereinafter referred to as the "second locked portion 48").

[0042] Furthermore, as shown in Figures 11 to 13, the second locking portion 49 is positioned between the temporary locking portion 47 and the second locked portion 48, thereby setting the door member 7 to a temporarily closed position. In this embodiment, when the door member 7 is in the temporarily closed position, the second locking portion 49 is in substantially contact with both the temporary locking portion 47 and the second locked portion 48. The contact between the second locking portion 49 and the temporary locking portion 47 restricts displacement toward the closed position, and the contact between the second locking portion 49 and the second locked portion 48 restricts displacement toward the open position. In addition, the second locking portion 49 is provided only near the right side of the closing portion 32, corresponding to the temporary locking portion 47 which is provided only on the right edge of the input opening 6 (see Figure 5). In this embodiment, the temporary holding means is composed of the second locking portion 49, the temporary locking portion 47, and the second locked portion 48. Furthermore, as shown in Figure 13, the second locking portion 49 has a rounded chamfer shape on both the front corner of the container 1 and the rear corner of the container 1 when the door member 7 is in the closed position. In addition, the protrusion length of the second locking portion 49 from the closing portion 32 is shorter than the protrusion length of the regulating portion 36 from the closing portion 32 (see Figure 13), and is about the same as the protrusion length of the locking projection 43 from the closing portion 32 (see Figure 12).

[0043] Furthermore, when the second locking portion 49 passes the second locked portion 48 in the rotational direction of the door member 7, the second locking portion 49 passes by sliding inward (downward) relative to the second locked portion 48. That is, when the door member 7 is moved from the open position to the temporarily closed position, the second locking portion 49 is configured to be displaceable from a state where it is located inside the container 1, sliding in contact with the second locked portion 48 and moving toward the input opening 6 side (outside the container 1) relative to the second locked portion 48. Moreover, when the second locking portion 49 passes the temporary locking portion 47 in the rotational direction of the door member 7, the second locking portion 49 passes by sliding in contact with the temporary locking portion 47 and sliding inward (downward) relative to the container 1. In addition, as shown in Figures 8 to 10, in this embodiment, when the door member 7 is in the closed position, the rear surface of the second locking portion 49 on the container 1 is in substantially contact with the front surface of the temporary locking portion 47 on the container 1. As a result, even the side (right side) of the door member 7 in the closed position is restricted from moving toward the open position.

[0044] Furthermore, as shown in Figures 14 and 16, when the door member 7 is in the open position, the right side of the restricting portion 36 is positioned between the second locked portion 48 and the temporary locked portion 47, and the restricting portion 36 contacts the temporary locked portion 47, thereby restricting the displacement of the door member 7 toward the closed position. Here, when the restricting portion 36 passes the temporary locked portion 47 in the rotational direction of the door member 7, the restricting portion 36 does not pass by going under the temporary locked portion 47 toward the inside (downward) side of the container 1, but rather passes by avoiding the inside side of the input opening 6.

[0045] As shown in Figures 10, 13, and 16, the closing part 32 is configured such that, regardless of whether the door member 7 is in the closed position, the temporarily closed position, or the open position (even in a predetermined position other than the temporarily closed position between the open and closed positions), the container 1 fits inside the lid body 5 when viewed from the direction of the rotation axis of the door member 7 (it does not protrude outside the container 1 beyond the lid body 5). In this embodiment, the only parts of the door member 7 that are visible when viewing the container 1 from the side are the tip portions of the operating part 37 and the restricting part 36 (and the connecting parts between the operating part 37 and each restricting part 36) (see Figures 9 and 10). Furthermore, as shown in Figures 8 and 11, when the door member 7 is in the temporarily closed position or the closed position, the second locking part 49 provided on the outer surface (surface) of the closing part 32 is visible from outside the container 1.

[0046] As shown in Figures 5, 9, and 10, the door member 7 has a cover portion 51 that protrudes from the leading edge of the closing portion 32 (the edge not connected to the back plate portion 33) when the door member 7 moves from the open position to the closed position, toward the closed position side of the door member 7 (downward when the door member 7 is in the closed position). In contrast, as shown in Figures 3 and 12, the lid body 5 has a lid cover portion 52 that overlaps with the cover portion 51 in the inward and outward direction of the container 1 when the door member 7 is in the temporarily closed position, and is provided such that the overlapping area increases when the container is closed, as shown in Figure 9. In this embodiment, the lid cover portion 52 is formed by the portion of the vertical wall portion 22 on one of the long sides where the input opening 6 is provided, located below the input opening 6, and the upper edge of the lid cover portion 52 forms the lower edge of the input opening 6. Furthermore, the portion of the vertical wall 22 on one of the longer sides where the input opening 6 is provided that constitutes the lid cover portion 52 is configured to be located on the inner side of the lid body 5 than the portions on either side thereof.

[0047] As shown in Figures 14 to 16, the door member 7 is equipped with a placement section 54 on the inside of the lid 4 that allows an item to be placed when the door member 7 is in the open position. The door member 7 is configured to fall into the storage section 3 of the container body 2 when it is displaced from the open position toward the closed position. As shown in Figure 6, etc., the back side of the placement section 54 is provided with placement reinforcing ribs 55 that are provided at predetermined intervals in the width direction of the container 1. The back plate section 33 of the door member 7 extends approximately vertically at the top when the door member 7 is in the closed position, and the lower part is inclined downward toward the rear of the container 1. The placement section 54 extends approximately vertically downward from the lower edge of the back plate section 33 when the door member 7 is in the closed position.

[0048] As shown in Figure 15, the lid body 5 has an inclined portion 56 that curves downward from the area on the inner edge of the flange portion 21 where the lid cover portion 52 is provided and protrudes toward the inner circumference of the flange portion 21, and is capable of guiding items that have fallen from the resting portion 54 toward the inside of the container 1. The lower edge of the inclined portion 56 is located slightly above the lower edge of the cover portion 25. In addition, a lid reinforcing portion 57 is provided that connects the inclined portion 56 and the inner frame portion 27.

[0049] As detailed above, according to this embodiment, even if the container 1 is equipped with a release operation unit 46, and the configuration makes it impossible to displace the door member 7 to the open position by simply operating the operation unit 37 when the container 1 is in the closed position with the door member 7 in the closed position, it becomes possible to displace the door member 7 to the open position and open the container 1 by operating the operation unit 37 (closing operation) while pressing the release operation unit 46. This allows an operator who recognizes the operation of the release operation unit 46 to open the container 1 from the closed position without damaging it, while also making the container 1 relatively difficult to open (sealable) once closed, thus preventing accidental or inappropriate contact with the articles (contents) contained in the container 1 after the container 1 has been closed. Therefore, while relatively strict control is maintained over contact with the articles contained in the container 1, even if the door member 7 is accidentally closed when there is ample space in the container 1, for example, the container 1 can be opened again and used more efficiently. Furthermore, for example, if there is no set method for opening a container that is in a closed state, and the container is forcibly opened while being damaged, it is possible to avoid situations where the contents spill out unintentionally when opening the container, thus allowing the operation of opening container 1 to be performed suitably (safely). As a result, the convenience of opening and closing the door member 7 can be improved. Moreover, compared to a configuration in which, for example, container 1 cannot be opened and becomes unusable once it is closed, it is possible to prevent unintentional contact with the items between the point where items are placed and the point where items are removed. This further expands the ways in which container 1 can be used.

[0050] Furthermore, in this embodiment, the closing portion 32 of the door member 7 has a substantially arc-shaped cross-section, and the door member 7 is connected to the lid body 5 so as to be rotatably displaceable, thereby ensuring the opening area of ​​the input opening 6 as wide as possible while minimizing the enlargement of the lid body 4. In addition, by configuring the closing portion 32 of the door member 7 in the open position to fit inside the lid body 5 in a side view (not protruding outside the container 1 beyond the lid body 5), the door member 7 (first locking portion 44, release operation portion 46, etc.) can be protected when the container 1 is open, and the door member 7 is kept undamaged or with minimal damage until the container 1 is closed, allowing the door member 7 to function more reliably when the container 1 is closed. Moreover, by arranging the release operation portion 46 and the operation portion 37 spaced apart from each other, it is possible to prevent the operation portion 37 from being displaced or deformed based on operation of the release operation portion 46. In addition, the arrangement allows the operator to simultaneously operate both the release operation unit 46 and the operation unit 37 with one hand, thereby improving the work efficiency when opening the container 1 from a closed state (by holding the container 1 with the other hand to safely open it).

[0051] Furthermore, the door member 7 is configured to be held in a temporarily closed position, which is a position between the open position and the closed position (a state in which most of the input opening 6 is closed by the closing part 32, but the closing part 32 does not completely close the input opening 6). As a result, even though the door member 7 has not yet reached the stage of being in the closed position, the door member 7 can be kept in the temporarily closed position except when an item is being put into the container 1 (for example, when there is a plan to store items in the container 1 in the future), thereby shielding the storage area 3 of the container 1 from the outside of the container 1 as much as possible and minimizing contact between the environment of the storage area 3 of the container 1 and the environment outside of the container 1. Consequently, it is possible to improve convenience in situations where it is undesirable for the environment of the storage area 3 of the container 1 to affect the outside of the container 1 (for example, for a person to come into contact with an item stored in the container 1), or for the environment outside of the container 1 to affect the storage area 3 of the container 1 (for example, for unwanted items such as garbage to enter the container 1, or for various instruments (for example, medical equipment or writing instruments) to enter the container 1).

[0052] Furthermore, the second locking portion 49 and the temporary locking portion 47 restrict the displacement of the door member 7 in the temporary closed position toward the closed position, and also restrict the displacement of the door member 7 in the closed position toward the open position. Therefore, while suppressing the complexity of the structure, the displacement of the door member 7 in the closed position toward the open position can be prevented more reliably (in cooperation with the first locking portion 44 and the first locked portion 45).

[0053] Furthermore, when the door member 7 is in the temporarily closed position, the second locking portion 49 is visible from outside the container 1. Therefore, it is possible to visually confirm and understand that the second locking portion 49 is located between the temporary locking portion 47 and the second locked portion 48, and consequently, that the door member 7 is in the temporarily closed position. In addition, when moving the door member 7 from the open position to the temporarily closed position, the second locking portion 49 moves from a state of sliding contact with the second locked portion 48 to a state where this sliding contact is released, allowing the user to understand that the door member 7 has been moved to the temporarily closed position by feel (click sensation). Thus, it is possible to prevent the door member 7 from being accidentally moved to the closed position when it was intended to be moved from the open position to the temporarily closed position.

[0054] In addition, the door member 7 is equipped with a restricting portion 36 that, when in the closed position, abuts against the lower edge of the loading opening 6 to restrict further rotational displacement. When the door member 7 is in the open position, the right end of the restricting portion 36 is positioned between the temporary locking portion 47 and the second locked portion 48, and abuts against the temporary locking portion 47 to restrict the displacement of the door member 7 toward the closed position. This makes it possible to maintain the open state of the door member 7, thus preventing situations such as the door member 7 unintentionally displacing toward the closed position when, for example, an item is placed in the storage section 3 of the container 1. Furthermore, by using the temporary locking portion 47 and the restricting portion 36 to maintain the open state, complexity of the structure can be suppressed, preventing situations such as reduced ease of opening and closing the door member 7, increased accumulation of dust, and reduced aesthetic appeal that can result from such complexity.

[0055] Furthermore, there are concerns that, for example, if manufacturing errors related to the second locking portion 49 or the temporary locking portion 47 occur, the engagement between the second locking portion 49 and the temporary locking portion 47 may become too large when the door member 7 is in the temporarily closed position, making it difficult (or impossible) to displace the door member 7 towards the closed position, or that when the container 1 is in the closed position, the engagement between the second locking portion 49 and the temporary locking portion 47 may become too large, making it difficult (or impossible) to displace the door member 7 towards the open position (temporarily closed position). In addition, there are concerns that it may be difficult to release the lock between the regulating portion 36 and the temporary locking portion 47 when the container 1 is in the open position. In this embodiment, the second locking portion 49 and the temporary locking portion 47 are provided only on the same side of the door member (the right side in this embodiment) in the width direction (axis direction of the door member 7) of the door member 7, and the temporary locking portion 47 is provided protruding inward from the side edge of the input opening 6 into the input opening 6. Therefore, when displacing the door member 7, the door member 7 is relatively displaced to the other side (left side) in the width direction of the door member 7, which reduces the engagement between the second locking portion 49 and the temporary locking portion 47 (and the engagement between the restricting portion 36 and the temporary locking portion 47), and the displacement of the door member 7 between the temporary closed position and the closed position (and the displacement of the door member 7 between the open position and the temporary closed position) can be performed relatively smoothly.

[0056] Furthermore, when the door member 7 is in the temporarily closed position, the closing part 32 does not completely close the input opening 6. However, the cover part 51, which is located on the closed side (below) the door member 7 than the closing part 32, and the lid cover part 52, which overlaps the cover part 51 in the inward and outward direction of the container 1 when the door member 7 is in the temporarily closed position and the closed position, allow the input opening 6 to be almost completely closed even when the door member 7 is in the temporarily closed position. Therefore, by keeping the door member 7 in the temporarily closed position except when inserting items into the container 1, the effect of minimizing contact between the storage area 3 of the container 1 and the outside of the container 1 is further enhanced. Furthermore, even if the container 1 were to tip over while the door member 7 is in the temporarily closed position, if the door member 7 is maintained in the temporarily closed position (the door member 7 is structured so that it will not fall off even if force is applied from the inside to the outside of the container 1, and when the door member 7 is pressed from the inside of the container 1, the locking state between the second locking part 49, the second locked part 48 and the temporary locking part 47 becomes stronger, making it easier to maintain the temporarily closed position), the cover part 51 and the lid cover part 52 can prevent items from flowing out of the container 1 through the input opening 6.

[0057] In addition, the door member 7 is equipped with a placement section 54 on the inside of the lid 4, which allows items to be placed when the door member 7 is in the open position. This helps to suppress variations in the orientation and falling speed of items placed (put into) the container 1. Furthermore, the inclined section 56 of the lid body 5 prevents items from piling up in one place in the storage section 3 of the container body 2 in a position that would obstruct the opening and closing of the door member 7. Therefore, items can be efficiently stored in the container 1 without the need for special work by the worker (for example, leveling the items stored in the container 1). In addition, by providing the inclined section 56 on the lid 4, the container body 2 can have a relatively simple shape, and the container bodies 2 can be stacked vertically, improving convenience during storage and transportation. Furthermore, even if the container 1 were to tip over while the door member 7 was in the open position, if the door member 7 remained in the open position (the door member 7 is designed so that it will not fall off even if force is applied from the inside to the outside of the container 1, and when the door member 7 is pressed from the inside of the container 1, the locking state between the restricting part 36, the second locking part 48, and the temporary locking part 47 becomes stronger, making it easier to maintain the open position), the placement part 54 and the inclined part 56 would restrict the displacement of the articles contained in the container 1 toward the input opening 6, thereby preventing the articles from flowing out of the container 1 through the input opening 6.

[0058] Furthermore, the embodiment is not limited to the description above, and may be implemented as follows, for example. Of course, other applications and modifications not exemplified below are also possible.

[0059] (a) The position of the release operation part 46 in the above embodiment is not particularly limited and can be changed as appropriate depending on the shape and use of the door member 7 and the lid body 5. For example, in the above embodiment, the release operation part 46 is provided on the door member 7, but the release operation part may be provided on the lid body 5. As an example of the configuration, a finger rest part may be provided in or near the operation housing recess 39 of the lid body 5, which protrudes toward the input opening 6 side and allows an operator to place their fingertips on the lower side and apply upward force, or a gripping part may be provided which protrudes upward and allows an operator to pinch it and apply upward force. When this configuration is adopted, when opening the door member 7 from the closed state, the finger rest part or gripping part can be operated to deform the surrounding part upward, thereby displacing the first locked part 45 upward, and the locked state between the first locked part 44 and the first locked part 45 can be released by operating the operation part 37 while maintaining that state. When this configuration is adopted, the release operation part is composed of a part operated by the worker, such as a finger rest or a gripping part, and a part that deforms in response to the operation to displace the first locking part 45. The configuration of the first locking part 44 and the first locking part 45 and their surrounding parts is not particularly limited, and can be modified as appropriate, for example, by omitting the locking projection 41 to improve the rotational operability of the door member 7, or by omitting the locking projection 43 so that the location of the locking structure is difficult to see from the outside when the container 1 is closed, and the locking structure can be housed inside the lid 4.

[0060] Furthermore, although the above embodiment provides one release operation unit 46, for example, multiple release operation units (i.e., locations where the locking state needs to be released in order to open the container 1) may be provided. For example, multiple release operation units (e.g., two locations) may be provided spaced apart from each other, so that it is impossible for one worker to operate all the release operation units and the operation unit 37 at the same time, even if using both hands. In this case, multiple people (e.g., two people) will be required to open a container that is in a closed state, and handling of the items contained in the closed container can be made more stringent. The distance between the release operation unit 46 and the operation unit 37 can be changed not only by changing the position of the release operation unit 46, but also by changing the position of the operation unit 37.

[0061] (b) In the above embodiment, the closing portion 32 of the door member 7 has a substantially arc-shaped cross-section and is configured to be rotatably displaceable, but the shape and operation of the door member 7 can be changed as appropriate. For example, the door member may be substantially flat, the input opening may be square frame-shaped, and rail portions supporting the sides of the door member may be provided at a pair of opposing side edges of the input opening, thereby configuring the door member to be slidably displaceable by changing the opening area of ​​the input opening. In the door member with this configuration, by providing a first locking portion and a second locking portion, it is held in the closed position and the temporarily closed position, respectively, and when the door member is in the closed position, the peripheral portion of the first locking portion (release operation portion) is pressed inward towards the container 1, and when the operation portion provided on the door member is operated, the locking state between the first locking portion and the first locked portion is released, and it is configured to be displaceable to the open position.

[0062] (c) In the above embodiment, the door member 7 is held in a temporarily closed position by positioning the second locking portion 49 of the door member 7 between the second locked portion 48 and the temporary locking portion 47 of the lid body 5 in the rotational direction of the door member 7. However, for example, in addition to the second locking portion 49, the door member 7 may be provided with a third locking portion that faces the second locking portion 49 in the rotational direction of the door member 7 and protrudes outward from the closing portion 32 toward the container 1. The door member 7 may be positioned in a temporarily closed position by positioning the temporary locking portion 47 or the second locked portion 48 (the temporary locking portion 47 can be omitted if the second locked portion 48 is used) between the second locking portion 49 and the third locking portion in the rotational direction of the door member 7.

[0063] (d) In the above embodiment, the operating part 37 is provided at a position spaced apart from the edge of the closing part 32 that is not connected to the back plate part 33. However, it may also be configured to protrude outward from such edge to the door member 7 (protruding more outward from the door member 7 than the restricting part 36). In this case, it becomes possible to omit the operating housing recess 39 (omit the extended shape of the closing part 32). Furthermore, a configuration in which the operating part 37 is used in conjunction with the restricting part 36 may be adopted, including a configuration in which the operating part 37 protrudes outward from the edge of the closing part 32 that is not connected to the back plate part 33 to the door member 7 (for example, a configuration in which the operating part 37 is provided continuously in the horizontal direction with the restricting part 36). For example, if the shape that constituted the operating part 37 in the above embodiment is omitted, the door member 7 will be opened and closed by operating the restricting part 36.

[0064] (e) In the above embodiment, the container body 2, the lid body 5, and the door member 7 are made of polypropylene, but they may be made of other resin materials such as polyethylene, PET, or polyamide. Furthermore, the articles to be contained in the container 1 are not particularly limited and can be changed as appropriate. However, since the container has a configuration that makes it relatively difficult to open when closed, the function of the container 1 can be fully demonstrated by using it as a container for transporting articles that require careful handling, such as used syringes.
