Description

[Technical field]

[0001] The present invention relates to a container having a lid. [Background technology]

[0002] Conventionally, a container for storing items such as medical waste has been known which comprises a box-shaped container body that opens upward and a lid body that can close the opening of the container body, the lid body having an insertion opening through which items can be inserted and which is attached to the container body, and a door member that opens and closes the insertion opening (see, for example, Patent Document 1, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2003-285856 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the container of Patent Document 1 is configured such that once the input opening is closed with the door member, the locking portion provided on the lid body is locked to the back side of the lid body, resulting in a sealed state and basically making it impossible (difficult) to open. For this reason, there are concerns that the convenience of opening and closing the door member is low, such as the need to discard the container as it is because the door member was accidentally closed when there is still room in the container's storage space, or the need to carefully damage the container without touching the contents in order to open it in order to search the container's storage space after sealing.

[0005] The present invention has been made to solve the problems exemplified above, and an object of the present invention is to provide a container that can improve convenience in terms of opening and closing a door member. [Means for solving the problem]

[0006] The following describes each of the means suitable for achieving the above objects. Note that, as necessary, the specific effects of the corresponding means will be added.

[0007] Means 1. A container body having a generally box-like shape that opens upward and has a storage section capable of storing an article, and a lid body that can close the opening of the container body. The lid body is attached to the container body and is made of a synthetic resin. The lid body has an insertion opening through which an article can be inserted. The lid body is made of a synthetic resin and is displaceable between an open position that opens the insertion opening and a closed position that closes the insertion opening. The door element includes an operating portion that is operated when displacing the door element, and a first locking portion that is locked to a first locked portion provided on the lid main body when the door element is in the closed position, A container comprising a temporary holding means for holding the door member in a temporary closed position between the open position and the closed position.

[0008] According to the means 1, the door element is configured to be held in a temporary closed position, which is a position between the open position and the closed position. As a result, although the door element has not yet reached the stage of being in the closed position, for example, the door element can be held in the temporary closed position except when an article is put into the container, and the space between the container storage section and the outside of the container can be blocked as much as possible, and the environment of the container storage section and the environment outside the container can be prevented from interfering with each other as much as possible. Therefore, it is possible to improve convenience in a situation where it is not desired that the environment of the container storage section affects the outside of the container (for example, a person touches an article stored in the container) or that the environment outside the container affects the container storage section (for example, unnecessary items such as garbage get into the container, or various tools get into the container).

[0009] Means 2. The temporary holding means is A second locking portion provided on the door member; a temporary locking portion provided on the lid body or the door member and configured to restrict the door member from being displaced toward the closed position when in the temporary closed position; The container described in Means 1 is characterized in that it is provided with a second engaged portion provided on the lid body and abuts against the second engaging portion of the door element in the temporary closed position to restrict displacement of the door element toward the open position.

[0010] According to the second aspect, the second locking portion and the temporary locking portion restrict the door element in the temporary closed position from being displaced toward the closed position, and restrict the door element in the closed position from being displaced toward the open position. Therefore, it is possible to more reliably prevent the door element in the closed position from being displaced toward the open position while suppressing the complexity of the configuration.

[0011] Means 3. A container as described in Means 2, characterized in that when the door element is changed from the open position to the temporary closed position, the second locking portion is configured to be displaceable from a state in which it is located inside the lid body to a state in which it slides against the second locked portion and is displaceable toward the input opening side relative to the second locked portion.

[0012] According to the third aspect, the second locking portion is released from the sliding contact with the second locked portion, and the user can know that the door element has been placed in the temporary closed position by a tactile sensation (click feeling). This makes it possible to prevent a situation in which the door element is mistakenly moved from the open position to the temporary closed position to the closed position.

[0013] Means 4. A container as described in Means 2 or 3, characterized in that the door element is provided with a regulating portion which abuts against the temporary locking portion when in the open position to regulate the displacement of the door element toward the closed position.

[0014] According to the fourth aspect, since it is possible to maintain the door element in the open position, it is possible to prevent, for example, a situation in which the door element is unintentionally displaced to the closed position when storing an article in the storage section of the container. In addition, the configuration that maintains the open state by utilizing the temporary locking portion makes it possible to suppress the complication of the configuration, and it is possible to prevent situations in which the operability of opening and closing the door element is reduced, dust and the like are easily accumulated, the design is deteriorated, and the like, which are caused by the complication of the configuration, are reduced.

[0015] Means 5. The door element includes a closing portion that closes the input opening when the door element is in the closed position, and a cover portion that protrudes from a leading edge of the closing portion toward the closed position of the door element when the door element moves from the open position to the closed position, A container described in any one of means 1 to 4, characterized in that the lid body is provided with a lid cover portion that overlaps with the cover portion in the inward and outward directions of the container when the door element is in the temporary closed position, and the overlapping area is increased in the closed state.

[0016] According to Means 5, when the door element is in the temporary closed position, the closing part does not completely close the input opening, but the cover part located on the closed position side of the door element from the closing part and the lid cover part can keep the input opening almost closed even when the door element is in the temporary closed position. Therefore, the door element is in the temporary closed position except when an article is being input into the container, blocking the space between the container storage part and the outside of the container as much as possible, thereby further achieving the effect of minimizing interaction between the environment of the container storage part and the environment outside the container.

[0017] Means 6. The door element has a placement portion on which an article can be placed inside the lid body when the door element is in the open position; The door member in the open position is displaced toward the closed position, so that an article placed on the placement section falls into the storage section of the container body, A container as described in any one of means 1 to 5, characterized in that the lid body has an inclined portion capable of guiding an article that has fallen from the placement portion toward the inside of the container.

[0018] According to the sixth aspect, the door member is provided with a placement portion, which makes it possible to suppress variations in the posture and falling speed of the articles stored (thrown) into the container. Furthermore, the inclined portion of the lid body makes it possible to prevent the articles from piling up in one place in the storage portion of the container body at a position that would prevent the opening and closing of the door member. Therefore, the articles can be efficiently stored in the container without the need for special work by an operator (for example, the work of leveling the articles stored in the container).

[0019] Means 7. The container body includes a bottom wall component having a generally rectangular shape in a plan view, and side wall components extending upward from the side edges of the bottom wall component, The bottom wall component includes a bottom inclined portion that is inclined downward from a connecting portion with a side wall portion at a position corresponding to the input opening of the side wall portion toward the opposing side wall portion, A container described in any one of means 1 to 6, characterized in that the side wall portion connected to the upper edge portion of the bottom inclined portion has a shape in which the portion directly below the portion connected to the bottom inclined portion is cut out.

[0020] Means 8. The door member is connected to the lid body so as to be pivotally displaceable; the door element has a substantially arc-shaped cross section in a direction perpendicular to the rotation axis direction of the door element, and includes a closing portion that closes the input opening when the door element is in the closed position; A container described in any one of means 1 to 7, characterized in that the closure portion is configured to fit inside the lid body when viewed from the side from the direction of the rotation axis of the door element when the door element is in the open position.

[0021] According to Means 8, the closing portion of the door element has a substantially arc-shaped cross section, and the door element is connected to the lid body so as to be rotatably displaceable, thereby ensuring a wide opening area of ​​the input opening while minimizing the increase in size of the lid body. Also, by configuring the closing portion of the door element in the open position to fit inside the lid body in a side view (not to protrude outside the container beyond the lid body), the door element (first locking portion, release operation portion, etc.) can be protected when the container is in the open state, and the door element is maintained in a state where it is not damaged or has only minimal damage until the container is closed, allowing the door element to function more reliably when the container is in the closed state.

[0023] An embodiment will be described below with reference to the drawings. As shown in Fig. 1, Fig. 2, etc., the container 1 is in the shape of a substantially square box that opens upward, and includes a container body 2 having a storage section 3 inside which an article (e.g., a used syringe, etc.) can be stored, and a lid body 4 that can close the opening of the container body 2. The lid body 4 is attached to the container body 2 and includes a lid body 5 having an input opening 6 through which an article can be input, 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] 2 and other figures, the container body 2 includes a bottom wall component 11 having a generally rectangular shape in plan view, a pair of opposing long side wall portions 12 extending upward from a pair of opposing long side edges of the bottom wall component 11, a pair of opposing short side wall portions 13 extending upward from a pair of opposing short side edges of the bottom wall component 11, a generally rectangular frame-shaped overhanging portion 14 protruding outward from the container body 2 from the entire upper edge portions of the long side wall portions 12 and the short side wall portions 13, and an edge wall portion 15 protruding downward from the entire outer edge portion of the overhanging portion 14. The container body 2 is configured with a tapered shape in which the long side wall portions 12 and the short side wall portions 13 are slightly inclined upward toward the outer side of the container body 2. 4, the container body 2 includes an upper frame reinforcing portion 16 that connects between the edge wall portion 15, the protruding portion 14, and the long side wall portion 12 or the short side wall portion 13. The container body 2 of this embodiment is integrally formed from polypropylene.

[0025] In addition, as shown in Fig. 2 etc., the bottom wall constituent part 11 has a bottom inclined part 17 that inclines downward from a connection part with one of the pair of long side sidewall parts 12 toward the other long side sidewall part 12. The bottom inclined part 17 is provided at a position spaced apart from each of the short side sidewall parts 13, and a part of the bottom wall constituent part 11 between the bottom inclined part 17 and each of the short side sidewall parts 13 extends in the horizontal direction. Also, the long side sidewall part 12 connected to the upper edge part of the bottom inclined part 17 has a shape in which a part directly below the part connected to the bottom inclined part 17 is cut out.

[0026] As shown in Figures 2 to 4, the lid body 5 comprises a substantially rectangular frame-shaped flange portion 21 that is placed on the protruding portion 14 of the container body 2 when attached to the container body 2, a long side vertical wall portion 22 that extends upward from the inner edges of a pair of opposing long sides of the flange portion 21, a short side vertical wall portion 23 that extends upward from the inner edges of a pair of opposing short sides of the flange portion 21, a top wall component 24 that connects the upper sides of the long side vertical wall portion 22 and the short side vertical wall portion 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 outer side of the container 1 when attached to the container body 2. In addition, the lid body 5 is provided with an attachment claw portion 26 that protrudes from the entire lower edge portion of the covering portion 25 toward the inner circumference of the covering portion 25, and an inner frame portion 27 that protrudes downward from the underside of the flange portion 21 around the entire circumference of the flange portion 21 and faces the inner surfaces of the long side side wall portion 12 and short side 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 FIG. 4 and other figures, when the lid body 5 (lid 4) is attached to the container body 2, the portions between the edge wall 15 and the long side wall 12 and the short side wall 13 of the container body 2 are inserted between the cover 25 and the inner frame 27 of the lid body 5, and the mounting claws 26 are engaged with the lower edge of the edge wall 15 of the container body 2. This basically makes it difficult (or impossible) to remove the lid 4 from the container body 2. The lower edge of the inner frame 27 is located higher than the lower edge of the cover 25. The lid body 5 of this embodiment is integrally formed of polypropylene. In addition, the mounting claws 26 can be provided partially in the circumferential direction of the cover 25 (for example, provided at multiple locations on each side of the cover 25).

[0028] 2, 3, etc., the lid body 5 is configured to have an R-shape that draws a substantially quarter-circular arc from a position slightly above the lower side of one of the long side vertical wall parts 22 to the top wall component 24, and the input opening 6 is provided in the R-shaped part so as to open the other part while leaving only a small part on both sides. In addition, a substantially U-shaped handle 28 is connected to the upper surface side of the top wall component 24 so as to be rotatable and displaceable. The handle 28 is configured to be displaceable between a lying position where it is accommodated in a concave handle accommodating part 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 Fig. 5 to Fig. 7, the door element 7 includes a pair of opposing side plate portions 31 each having a substantially quarter-circular plate shape, a closing portion 32 having a substantially arc-shaped cross section connecting between the arc-shaped portions of the pair of side plate portions 31, a back plate portion 33 connecting between one of the linear portions of the pair of side plate portions 31, and a shaft portion 34 protruding to the side of the door element 7 from a position of each side plate portion 31 that is substantially the center of the arc of the side plate portion 31. The peripheral portion of the shaft portion 34 of the side plate portion 31 is stepped so that the base portion of the shaft portion 34 protrudes slightly to the side beyond the side plate portion 31. The door element 7 of this embodiment is integrally formed from polypropylene.

[0030] On the other hand, as shown in Figs. 1 and 2, the lid body 5 is provided with a pivot support portion 35 on each short side vertical wall portion 23, which supports each shaft portion 34 of the door element 7 so as to be rotatable and displaceable. The distance between the outer surfaces of the pair of side plate portions 31 of the door element 7 is configured to be slightly shorter than the distance between the inner surfaces of the pair of short side vertical wall portions 23 of the lid body 5. The shaft portion 34 of the door element 7 is inserted into the pivot support portion 35 of the lid body 5, so that the door element 7 is connected to the lid body 5 so as to be rotatable and displaceable. As shown in Figs. 2 and 3, the pivot support portion 35 is formed by providing a circular through hole in the short side vertical wall portion 23 and slightly bulging outward at a lower portion of the through hole, and is configured to support the lower side of the shaft portion 34 with the arc-shaped upper edge portion 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 element 7 is connected to the lid body 5 from the lower side of the inner surface of the lid body 5).

[0031] In addition, the arc shape of the side plate portion 31 of the door element 7 corresponds to the R-shaped portion of the lid body 5, and as shown in Fig. 1 etc., when the door element 7 is connected to the lid body 5, both sides of the closing portion 32 are disposed opposite and adjacent to (or in contact with) the inner surface (rear surface) of the R-shaped portion 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 element 7 in which the input opening 6 is closed by the closing portion 32 as shown in Figs. 1 and 8 corresponds to the closed position, and the state in which the door element 7 is in the closed position corresponds to the closed state of the container 1.

[0032] Furthermore, as shown in Fig. 5 etc., the door element 7 is provided with a restricting portion 36 that protrudes outward from the door element 7 from the edge of the closing portion 32 on the side that is not connected to the back plate portion 33. As shown in Fig. 1 etc., when the door element 7 is connected to the lid body 5, the restricting portion 36 penetrates the input opening 6 and protrudes outward from the lid body 5, and as shown in Figs. 8 and 10, when the door element 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 Fig. 5 and Fig. 8, the restricting portion 36 in this embodiment is provided in a range including both end vicinity portions of the closing portion 32 (positions that do not interfere with the R-shaped portion of the lid body 5) in the direction of the rotation axis of the door member 7 (horizontal width direction), but is not provided in a range including the center portion of the closing portion 32. Instead, an operating portion 37 is provided that protrudes outward 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 forward of the front edge of the restricting portion 36 in the front-rear direction of the container 1, with the surface that is visible when the long side vertical wall portion 22 where the input opening 6 of the container 1 is viewed from the front is the front surface of the container 1 (see Figs. 8 to 10).

[0034] As shown in Fig. 14 etc., the door element 7 is rotated and displaced from the closed position by about 90 degrees so as to bring the restricting portion 36 closer to the upper edge of the input opening 6, to the open position. When the door element 7 is in the open position (the container 1 is in the open state), the portion of the closing portion 32 located closer to the back plate portion 33 than the restricting portion 36 and the operating portion 37 is accommodated inside the container 1 (lid body 5), and most of (almost the entire) the input opening 6 is opened. In addition, by placing a fingertip on the underside of the operating portion 37 with respect to the door element 7 in the closed position, it is possible to relatively easily displace the door element 7 to the open position.

[0035] 2, 3, etc., the top wall forming portion 24 of the lid main body 5 forms the upper edge of the input opening 6 and has an upper edge defining portion 38 extending in the vertical direction. Also, as shown in Figs. 2 and 14, the upper edge defining portion 38 has an operation accommodating recess 39 in which the operation portion 37 of the door element 7 is accommodated when the door element 7 is in the open position. This allows the restricting portion 36 to abut against the upper edge (upper edge defining portion 38) of the input opening 6 (see Fig. 6), and the restricting portion 36 abuts against the upper edge defining portion 38 to restrict further rotational displacement of the door element 7.

[0036] As shown in Figs. 14 and 15, the top wall forming part 24 of the lid body 5 is provided with an operation allowable recess 40 that lowers the height of a part of the upper edge defining part 38 including the central part in the width direction of the operation accommodation recess 39. As a result, even when the door element 7 is in the open position and the operation part 37 is accommodated inside the operation accommodation recess 39, it is possible to hook a finger on the rear side of the container 1 of the operation part 37 through the operation allowable recess 40 (pinch the operation part 37) and displace the door element 7 to the closed position (closing operation of the operation part 37). Also, as shown in Fig. 8, the closing part 32 is formed to extend toward the operation accommodation recess 39 side so that the part of the input opening 6 corresponding to the operation accommodation recess 39 can also be closed by the closing part 32 by setting the door element 7 to the closed position (see Fig. 6).

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

[0038] In this embodiment, even if the door element 7 is moved to the open position by operating the operation part 37 of the door element 7 in the closed position, the first locking part 44 and the first locked part 45 are locked relatively firmly (the overlapping area in the direction of the rotational displacement of the door element 7, i.e., the locking margin, is relatively large), so that the door element 7 cannot be moved to the open position. However, as shown in Fig. 8, by pressing a part of the closing part 32 of the door element 7 that is slightly displaced from the first locking part 44 toward the center of the closing part 32 (hereinafter referred to as "release operation part 46") toward the inside (downward) of the container 1, the vicinity of the part is deformed so as to bend toward the inside of the container 1. Furthermore, the first locking portion 44 is displaced inwardly of the container 1 based on the deformation (or the first locking portion 44 is tilted and displaced toward the front of the container 1), and by operating the operation portion 37 (operating the release operation portion 46 and the operation portion 37 simultaneously) while maintaining the displaced state, the locked state between the first locking portion 44 and the first locked portion 45 can be released and the door element 7 can be displaced to the open position. As shown in Fig. 9, the corners of the locking protrusion 43 on the front side of the container 1 when the door element 7 is in the closed position are rounded, while the corners on the rear side of the container 1 are not chamfered.

[0039] Furthermore, although the resolving operation unit 46 and the operation unit 37 are disposed apart from each other, they are disposed so that an operator can simultaneously operate both the resolving operation unit 46 and the operation unit 37 with one hand. In this embodiment, the container 1 is not provided with a mark indicating the resolving operation unit 46 or a display showing how to operate the resolving operation unit 46, and only an operator who is aware in advance of the operation of the resolving operation unit 46 can open the container 1 from the closed state.

[0040] 11, in this embodiment, the door element 7 is configured to be able to be held in a temporary closed position between the open position and the closed position. That is, the lid body 5 is provided with a temporary locking portion 47 that protrudes inwardly from 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 FIGS. 2 and 3).

[0041] In contrast, the door element 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 closure portion 32, as shown in Fig. 5. The second locking portion 49 is located forward of the temporary locking portion 47 when the door element 7 is in the closed position as shown in Fig. 9, and is located rearward of the container 1 (inside the container 1) of a portion of the upper edge defining portion 38 on the side of the operation-accommodating recess 39 (hereinafter referred to as "second locked portion 48") when the door element 7 is in the open position as shown in Fig. 13.

[0042] Further, as shown in Figs. 11 to 13, the second locking portion 49 is positioned between the temporary locking portion 47 and the second locked portion 48, so that the door element 7 is in the temporary closed position. In this embodiment, when the door element 7 is in the temporary closed position, the second locking portion 49 is in a state of substantially abutment with both the temporary locking portion 47 and the second locked portion 48, and the second locking portion 49 abuts against the temporary locking portion 47 to restrict displacement toward the closed position, and the second locking portion 49 abuts against the second locked portion 48 to restrict displacement toward the open position. The second locking portion 49 is provided only near the right side of the closing portion 32 in correspondence with the temporary locking portion 47 provided only on the right edge of the input opening 6 (see Fig. 5). In this embodiment, the second locking portion 49, the temporary locking portion 47, and the second locked portion 48 form a temporary holding means. 13 and other figures, the second locking portion 49 has a rounded chamfer shape at both the corners on the front side of the container 1 when the door member 7 is in the closed position and at the corners on the rear side of the container 1. Furthermore, the protruding length of the second locking portion 49 from the closing portion 32 is shorter than the protruding length of the restricting portion 36 from the closing portion 32 (see FIG. 13) and is approximately the same as the protruding length of the locking projection 43 from the closing portion 32 (see FIG. 12).

[0043] Furthermore, when the second locking portion 49 passes through the second locked portion 48 in the rotation direction of the door element 7, the second locking portion 49 passes through while slipping under the second locked portion 48 toward the inside (below) of the container 1. That is, when the door element 7 is changed from the open position to the temporary closed position, the second locking portion 49 is configured to be displaceable from a state in which it is located inside the container 1 to the input opening 6 side (outside the container 1) beyond the second locked portion 48 by sliding against the second locked portion 48. Furthermore, when the second locking portion 49 passes through the temporary locking portion 47 in the rotation direction of the door element 7, the second locking portion 49 passes through while sliding under the temporary locking portion 47 toward the inside (below) of the container 1. 8 to 10, in this embodiment, when the door element 7 is in the closed position, the surface of the second locking portion 49 on the rear side of the container 1 is in a state of substantially abutting against the surface of the provisional locking portion 47 on the front side of the container 1. This restricts the displacement of the door element 7 towards the open position even at the side (right side) of the door element 7 in the closed position.

[0044] 14 and 16, when the door element 7 is in the open position, the right side of the restricting portion 36 is located between the second locked portion 48 and the temporary locking portion 47, and the restricting portion 36 comes into contact with the temporary locking portion 47, thereby restricting the displacement of the door element 7 toward the closed position. Here, when the restricting portion 36 passes through the temporary locking portion 47 in the rotation direction of the door element 7, the restricting portion 36 does not pass under the temporary locking portion 47 so as to go under the temporary locking portion 47 on the inside side of the container 1, but passes by avoiding the inside of the input opening 6.

[0045] As shown in Figs. 10, 13, 16, etc., the closing part 32 is configured to be accommodated inside the lid body 5 (does not protrude outside the lid body 5) when the container 1 is viewed from the side in the direction of the rotation axis of the door element 7, regardless of whether the door element 7 is in the closed position, the temporary closed position, or the open position (even if the door element 7 is in a predetermined position other than the temporary closed position between the open position and the closed position). In this embodiment, the only parts of the door element 7 that are visible when the container 1 is viewed from the side are the operation part 37 and the tip side parts of the restriction part 36 (as well as the connection part between the operation part 37 and each restriction part 36) (see Figs. 9, 10, etc.). Furthermore, as shown in Figs. 8 and 11, when the door element 7 is in the temporary closed position and the closed position, the second locking part 49 provided on the outer surface (front surface) side of the closing part 32 is visible from the outside of the container 1.

[0046] As shown in Figs. 5, 9, 10, etc., the door element 7 has a cover part 51 that protrudes from the leading edge part (the edge part not connected to the back plate part 33) of the closing part 32 when the door element 7 moves from the open position to the closed position to the closed position side of the door element 7 (downward when the door element 7 is in the closed position). In contrast, as shown in Figs. 3, 12, etc., the lid body 5 has a lid cover part 52 that overlaps with the cover part 51 in the inside and outside direction of the container 1 when the door element 7 is in the temporary closed position, and is provided so that the overlapping area increases in the closed state as shown in Fig. 9, etc. In this embodiment, the lid cover part 52 is formed by a part located below the input opening 6 of one of the long side vertical wall parts 22 on which the input opening 6 is provided, and the lower edge part of the input opening 6 is formed by the upper side part of the lid cover part 52. Furthermore, the portion of one of the long side vertical walls 22 on which the insertion opening 6 is provided that constitutes the lid cover portion 52 is configured to be located more inward of the lid main body 5 than the portions on both sides thereof.

[0047] As shown in Figs. 14 to 16, the door element 7 has a placement portion 54 on which an article can be placed inside the lid body 4 when the door element 7 is in the open position. The door element 7 in the open position is displaced toward the closed position, so that the article placed on the placement portion 54 falls into the storage portion 3 of the container body 2. As shown in Fig. 6 and other figures, placement reinforcement ribs 55 are provided on the back side of the placement portion 54 at predetermined intervals in the width direction of the container 1. When the door element 7 is in the closed position, the upper part of the back plate portion 33 of the door element 7 extends in a substantially vertical direction, and the lower part is inclined downward toward the rear of the container 1. When the door element 7 is in the closed position, the placement portion 54 extends in a substantially vertical direction downward from the lower edge of the back plate portion 33.

[0048] 15 and other figures, the lid body 5 has an inclined portion 56 that protrudes downward and curves toward the inner periphery of the flange 21 from the range of the inner edge of the flange 21 where the lid cover portion 52 is provided, and can guide an article that has fallen from the placement 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 that connects the inclined portion 56 and the inner frame portion 27 is provided.

[0049] As described above in detail, according to this embodiment, since the container 1 includes the cancellation operation unit 46, even if the door element 7 cannot be displaced to the open position side by only operating the operation unit 37 in the closed state of the container 1 with the door element 7 in the closed position, the door element 7 can be displaced to the open position and the container 1 can be opened by operating the operation unit 37 (closing operation) while pressing the cancellation operation unit 46. This allows a configuration in which an operator who recognizes the operation of the cancellation operation unit 46 can open the container 1 in the closed state as necessary without damaging it, and the container 1 can be made relatively difficult to open by closing it (sealable), and it is possible to prevent accidental or inappropriate contact with the items (contained items) contained in the container 1 after the container 1 is closed. Therefore, while relatively strict management of contact with the items contained in the container 1 is performed, for example, even if the door element 7 is mistakenly closed when there is a margin of storage space in the container 1, the container 1 can be opened again and the container 1 can be used more efficiently. In addition, for example, when a method for opening a container in a closed state is not set and the container is opened (forcefully) while damaging it, it is possible to avoid a situation in which the contents accidentally fly out when opening the container 1, and the operation of opening the container 1 can be performed suitably (safely). As a result, it is possible to improve the convenience of opening and closing the door member 7. Furthermore, compared to a configuration in which the container 1 cannot be opened once it is closed and cannot be used thereafter, it is possible to prevent accidental contact with an item between a point where an operation for storing an item is performed and a point where an operation for removing the item is performed. This allows the number of ways in which the container 1 can be used to be further increased.

[0050] In addition, in this embodiment, the closing portion 32 of the door element 7 has a substantially arc-shaped cross section, and the door element 7 is connected to the lid body 5 so as to be rotatably displaceable, so that the opening area of ​​the input opening 6 can be secured as wide as possible while minimizing the increase in size of the lid body 4. In addition, the closing portion 32 of the door element 7 in the open position is configured to be accommodated inside the lid body 5 in a side view (does not protrude outside the container 1 beyond the lid body 5), so that the door element 7 (the first locking portion 44, the release operation portion 46, etc.) can be protected when the container 1 is in the open state, and the door element 7 is maintained in a state where there is no or only a small amount of damage until the container 1 is closed, so that the door element 7 can function more reliably when the container 1 is closed. Furthermore, the release operation portion 46 and the operation portion 37 are arranged apart from each other, so that the operation portion 37 can be prevented from being displaced or deformed based on the operation of the release operation portion 46. In addition, by arranging the operation unit 46 and the operation unit 37 so that an operator can simultaneously operate both with one hand, the ease of operation when opening a closed container 1 can be improved (the operator can hold the container 1 with the other hand to safely open it).

[0051] Furthermore, the door element 7 is configured to be able to be held in a temporary closed position (a state in which the closing portion 32 closes most of the input opening 6 but does not completely close the input opening 6) which is a position between the open position and the closed position. As a result, although the stage of setting the door element 7 to the closed position has not been reached, for example, the door element 7 can be set to the temporary closed position except when putting an article into the container 1 (when there is a plan to store articles in the container 1 in the future), and the door element 7 can be kept in the temporary closed position, blocking the space between the storage section 3 of the container 1 and the outside of the container 1 as much as possible, thereby minimizing the interaction between the environment of the storage section 3 of the container 1 and the environment outside the container 1. Therefore, it is possible to improve convenience in a situation in which it is not desired that the environment of the storage section 3 of the container 1 affects the outside of the container 1 (for example, a person touches an article stored in the container 1) or that the environment outside the container 1 affects the storage section 3 of the container 1 (for example, unnecessary items such as garbage enter the container 1, or various instruments (for example, medical equipment and writing utensils) enter the container 1).

[0052] Furthermore, the second locking portion 49 and the temporary locking portion 47 regulate the door element 7 in the temporary closed position from being displaced toward the closed position, and also regulate the door element 7 in the closed position from being displaced toward the open position. Therefore, it is possible to more reliably prevent the door element 7 in the closed position from being displaced toward the open position (in cooperation with the first locking portion 44 and the first locked portion 45) while suppressing a complex configuration.

[0053] Furthermore, when the door element 7 is in the temporary closed position, the second locking portion 49 is visible from the outside of the container 1. Therefore, it is possible to visually confirm that the second locking portion 49 is located between the temporary locking portion 47 and the second locked portion 48, and therefore that the door element 7 is in the temporary closed position. In addition, when the door element 7 is moved from the open position to the temporary closed position, the second locking portion 49 goes from a state of sliding contact with the second locked portion 48 to a state of being released from the sliding contact, and it is possible to know by a tactile sensation (click sensation) that the door element 7 is in the temporary closed position. Therefore, it is possible to prevent a situation in which the door element 7, which is intended to be moved from the open position to the temporary closed position, is mistakenly moved to the closed position.

[0054] In addition, the door element 7 includes a restricting portion 36 that, when in the closed position, abuts against the lower edge of the input opening 6 to restrict further rotational displacement, and when the door element 7 is in the open position, the right end of the restricting portion 36 is located between the provisionally locked portion 47 and the second locked portion 48, and abuts against the provisionally locked portion 47 to restrict the displacement of the door element 7 toward the closed position. This allows the door element 7 to be held in the open position, so that it is possible to prevent, for example, the door element 7 from being unintentionally displaced toward the closed position when storing an article in the storage section 3 of the container 1. In addition, the configuration that uses the provisionally locked portion 47 and the restricting portion 36 to hold the open state can suppress the complexity of the configuration, and can suppress situations such as a decrease in the opening and closing operability of the door element 7, an increase in the tendency for dust to accumulate, and a decrease in design due to the complexity of the configuration.

[0055] In addition, for example, if a manufacturing error or the like occurs related to the second locking portion 49 or the temporary locking portion 47, there is a concern that when the door element 7 is in the temporary closed position, the engagement between the second locking portion 49 and the temporary locking portion 47 becomes too large, making it difficult (unable to displace) the door element 7 to the closed position, or when the container 1 is in the closed state, the engagement between the second locking portion 49 and the temporary locking portion 47 becomes too large, making it difficult (unable to displace) the door element 7 to the open position (temporarily closed position). Furthermore, there is a concern that when the container 1 is in the open state, it is difficult to release the engagement between the restricting portion 36 and the temporary locking portion 47. In this respect, in the present embodiment, in the width direction of the door element 7 (axial direction of the door element 7), the second locking portion 49 and the temporary locking portion 47 are provided only on the same side (the right side in the present embodiment) of the door element, and the temporary locking portion 47 is provided protruding from the side edge of the input opening 6 toward the inside of the input opening 6. Therefore, by relatively displacing the door element 7 toward the other side (left side) in the width direction of the door element 7 when displacing the door element 7, the engagement allowance between the second locking portion 49 and the temporary locking portion 47 (as well as the engagement allowance between the restricting portion 36 and the temporary locking portion 47) can be reduced, and the door element 7 can be displaced relatively smoothly between the temporary closed position and the closed position (as well as between the open position and the temporary closed position).

[0056] Furthermore, when the door element 7 is in the temporary closed position, the closing part 32 does not completely close the input opening 6, but the input opening 6 can be almost closed even when the door element 7 is in the temporary closed position by the cover part 51 located on the closed position side (lower) of the door element 7 than the closing part 32 and the lid cover part 52 overlapping the cover part 51 in the inward and outward directions of the container 1 when the door element 7 is in the temporary closed position and the closed position. Therefore, the door element 7 is in the temporary closed position except when an article is being input into the container 1, blocking the space between the storage part 3 of the container 1 and the outside of the container 1 as much as possible, thereby further achieving the effect of minimizing interaction between the environment of the storage part 3 of the container 1 and the environment outside the container 1. Furthermore, even if the container 1 falls over while the door element 7 is in the temporary closed position, as long as the door element 7 is maintained in the temporary closed position (the door element 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 element 7 is pressed from the inside of the container 1, the engagement between the second locking portion 49 and the second locked portion 48 and the temporary locking portion 47 becomes stronger, making it easier to maintain the temporary closed position), the cover portion 51 and the lid cover portion 52 can prevent items from spilling out of the container 1 through the input opening 6.

[0057] In addition, the door element 7 is provided with a placement section 54 on which an article can be placed inside the lid body 4 when the door element 7 is in the open position. This makes it possible to suppress variations in the posture and fall speed of the article stored (thrown) in the container 1. Furthermore, the inclined section 56 of the lid body 5 makes it possible to prevent the articles from piling up in one place in the storage section 3 of the container body 2 at a position that would prevent the door element 7 from opening and closing. Therefore, the articles can be efficiently stored in the container 1 without special work by the worker (for example, work to level the articles stored in the container 1). In addition, by providing the inclined section 56 on the lid body 4, the container body 2 can be made to have a relatively simple shape, and the container bodies 2 can be configured to be stacked one on top of the other, thereby improving convenience during storage and transportation. Furthermore, even if the container 1 falls over while the door element 7 is in the open position, as long as the door element 7 is maintained in the open position (the door element 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 element 7 is pressed from the inside of the container 1, the engagement between the regulating portion 36 and the second engaged portion 48 and the temporary engaged portion 47 becomes stronger, making it easier to maintain the open position), the placement portion 54 and the inclined portion 56 restrict the displacement of items contained in the container 1 toward the input opening 6, thereby preventing the items from spilling out of the container 1 through the input opening 6.

[0058] The present invention is not limited to the above-described embodiment, and may be implemented as follows: 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 appropriately changed according to the shapes, applications, etc. of the door element 7 and the lid body 5. For example, in the above embodiment, the release operation part 46 is provided on the door element 7, but the release operation part may be provided on the lid body 5. As an example of the mode, a finger hook part that protrudes toward the input opening 6 side and enables an operator to hook his / her fingertips on the underside to apply upward force, or a knob part that protrudes upward and enables an operator to pinch and apply upward force, may be provided on the operation accommodation recess 39 of the lid body 5 or in its vicinity. When this configuration is adopted, when the door element 7 in the closed state is opened, the finger hook part or knob part is operated to deform the peripheral part upward, thereby displacing the first locked part 45 upward, and the operation part 37 is operated while maintaining that state, thereby disengaging the locked state between the first locked part 44 and the first locked part 45. When this configuration is adopted, the release operation section is made up of a portion operated by an operator, such as a finger hook or a knob, and a portion that deforms in response to this operation to displace first locked portion 45. The configuration of first locked portion 44 and first locked portion 45 and their surroundings is not particularly limited, and can be modified as appropriate, for example, by omitting locked protrusion 41 to improve the operability of turning door member 7, or by omitting locking protrusion 43 to configure the locking structure to fit inside lid 4 so that the location of the locking structure is difficult to see from the outside when container 1 is in the closed state.

[0060] In the above embodiment, the release operation unit 46 is provided at one location, but for example, the release operation unit (i.e., the location where the locked state needs to be released in order to open the container 1) may be provided at multiple locations. For example, the release operation units may be provided at multiple locations (e.g., two locations) spaced apart from each other, so that a single operator cannot operate all the release operation units while operating the operation unit 37 even with both hands. In this case, multiple people (e.g., two people) are required to open a container that is in a closed state, and the handling of the items contained in the container in the closed state can be made stricter. 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 element 7 has a substantially arc-shaped cross section and is configured to be rotatably displaceable, but the shape and operation of the door element 7 can be changed as appropriate. For example, the door element may be configured to be substantially flat, the input opening portion may be configured to have a rectangular frame shape, and rail portions that support the sides of the door element may be provided at a pair of opposing side edges of the input opening portion, so that the opening area of ​​the input opening portion may be changed to allow the door element to be slidably displaceable. In the door element configured as described above, the first locking portion and the second locking portion are provided to hold the door element in each of the closed position and the temporary closed position, and when the door element is in the closed position, the peripheral portion of the first locking portion (unlocking operation portion) is pressed toward the inside of the container 1, and the operation portion provided on the door element is operated to release the locking state between the first locking portion and the first locked portion, so that the door element can be displaced to the open position.

[0062] (c) In the above embodiment, the door element 7 is held in the temporary closed position by positioning the second locking portion 49 of the door element 7 between the second locked portion 48 and the temporary locked portion 47 of the lid body 5 in the rotation direction of the door element 7. However, for example, in addition to the second locking portion 49, the door element 7 may be provided with a third locking portion that protrudes from the closing portion 32 to the outside of the container 1 opposite the second locking portion 49 in the rotation direction of the door element 7, and the temporary locking portion 47 or the second locked portion 48 (the temporary locking portion 47 can be omitted when the second locked portion 48 side is used) may be positioned between the second locking portion 49 and the third locking portion in the rotation direction of the door element 7, so that the door element 7 is held in the temporary closed position. It is also possible to omit the configuration for holding the door element 7 in the temporary closed position.

[0063] (d) In the above embodiment, the operation unit 37 is provided at a position separated from the edge of the closing unit 32 on the side not connected to the back plate 33, but may be configured to protrude from the edge toward the outside of the door element 7 (protrude farther toward the outside of the door element 7 than the restricting unit 36). In this case, it is possible to omit the operation accommodation recess 39 (omit the expanded shape of the closing unit 32). In addition, a configuration in which the operation unit 37 is provided so as to protrude from the edge of the closing unit 32 on the side not connected to the back plate 33 toward the outside of the door element 7 (for example, a configuration in which the operation unit 37 is provided horizontally in a continuous line with the restricting unit 36) and the operation unit 37 also serves as the restricting unit 36 ​​may be adopted. For example, when the shape constituting the operation unit 37 in the above embodiment is omitted, the door element 7 is opened and closed by operating the restricting unit 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, polyamide, etc. In addition, the items stored in the container 1 are not particularly limited and can be changed as appropriate. However, since the container 1 has a configuration that makes it relatively difficult to open it when it is in the closed state, the functions of the container 1 can be fully exhibited by using it as a container for transporting items that require careful handling, such as used syringes.
