Mode for Carrying Out the Invention

[0016] Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIGS. 1 to 3 and the like, a trash can 1 as a container with a lid includes a substantially box-shaped container body 2 having an opening 3 that opens upward, a pair of lid members 4 that are attached to the container body 2 so as to be able to open and close the opening 3, a pedal 5 as an operating member that is operated by a user stepping on it with the tip of the foot, and a linkage member 6 that interlocks the lid members 4 in response to the operation of the pedal 5.

[0017] As shown in FIGS. 1, 4, 5 and the like, the container body 2 includes a bottom wall component 12 that is substantially rectangular in plan view, a pair of long side side wall components 13 that extend upward from a pair of opposite long side portions of the bottom wall component 12, and a pair of short side side wall components 14 that extend upward from a pair of opposite short side portions of the bottom wall component 12. The container body 2 further includes a projecting portion 15 that projects outward from the entire circumference of the upper edge portion of the accommodating portion 11, and a peripheral wall portion 16 that projects upward from the leading edge of the projecting portion 15. The accommodating portion 11 is configured in a tapered shape that widens upward. Note that the container body 2 of the present embodiment is integrally formed of polypropylene.

[0018] Also, as shown in FIG. 5, the overhanging portion 15 of the present embodiment includes a lower wall portion 17 extending from the upper edge portion of the accommodating portion 11 to the outer peripheral side of the container body 2, a vertical wall portion 18 extending upward from the leading edge portion of the lower wall portion 17, and an upper wall portion 19 extending from the upper edge portion of the vertical wall portion 18 to the outer peripheral side of the container body 2. Further, in the container body 2 of the present embodiment, a folding wall portion 20 is provided which is connected to the upper side portion of the portion corresponding to one of the short side side wall portions 14 (hereinafter also referred to as "front side side wall portion 14a") of the edge wall portion 16 and extends obliquely downward and outward of the container body 2. The folding wall portion 20 extends until its lower edge portion reaches the same height position as the lower surface of the overhanging portion 15. In addition, the folding wall portion 20 is also provided at the portion corresponding to the other short side side wall portion 14 (hereinafter also referred to as "rear side side wall portion 14b") and the pair of long side side wall portions 13. For the folding wall portion 20, it extends downward from the upper wall portion 19 in such a manner that the lower side portion of the edge wall portion 16 is extended downward (until its lower edge portion reaches the same height position as the lower surface of the overhanging portion 15).

[0019] As shown in FIGS. 6, 7, etc., each lid member 4 includes a substantially rectangular plate-shaped top wall portion 21 capable of closing the opening 3 of the container body 2, a frame wall portion 22 protruding downward from the outer peripheral edge of the top wall portion 21, and a substantially cylindrical shaft portion 23 protruding outward from the vicinity of one side end of the outer surface of the portion of the frame wall portion 22 corresponding to the short side portion of the top wall portion 21. Incidentally, the lid member 4 of the present embodiment is integrally formed of polypropylene.

[0020] Further, as shown in FIG. 3 and the like, the lid member 4 of the present embodiment is rotatably displaceably attached corresponding to each long-side side wall portion 13 of the container body 2. Specifically, at an upper position above the upper wall portion 19 of the portion corresponding to each long-side side wall portion 13 among the overhanging portions 15, the rotation axis 24 (see FIG. 6 and the like) of the lid member 4 is configured to extend along the upper side portion of the long-side side wall portion 13 and parallel to the lateral width direction of the long-side side wall portion 13. That is, as shown in FIG. 5, with respect to the portion having a surface corresponding to each short-side side wall portion 14 among the edge wall portions 16 (the surface facing the same side as the outer surface of each short-side side wall portion 14), at upper positions on both end sides of the upper wall portion 19 of the portion corresponding to each long-side side wall portion 13 among the overhanging portions 15, shaft holes 25 for rotatably supporting the shaft portion 23 of the lid member 4 are provided.

[0021] Also, the lid member 4 extends substantially parallel to the upper side portion of the short-side side wall portion 14 and is configured to be rotatably displaceable between a closed position (see FIG. 1 and the like) for closing the opening 3 of the container body 2 and an open position (see FIG. 3 and the like) that extends substantially orthogonally upward with respect to the upper side portion of the short-side side wall portion 14 and opens the opening 3 of the container body 2. When the lid member 4 is in the closed position, the lower side portion of the frame wall portion 22 of the lid member 4 is configured to abut against and be supported by the upper wall portion 19 corresponding to the short-side side wall portion 14 of the container body 2 (see FIGS. 13 and 15 and the like). Incidentally, as shown in FIG. 19 and the like, the upper wall portion 19 corresponding to the long-side side wall portion 13 is located slightly lower than the upper wall portion 19 corresponding to the short-side side wall portion 14, and the upper wall portion 19 corresponding to the long-side side wall portion 13 is configured not to hinder the rotation of the lid member 4. On the other hand, as shown in FIG. 22 and the like, when the lid member 4 is in the open position, the top wall portion 21 of the lid member 4 is configured to abut against and be supported by the inner surface of the edge wall portion 16 corresponding to the long-side side wall portion 13.

[0022] As shown in FIG. 9 and the like, the interlocking member 6 includes a lifting base portion 31 as a base portion having a pair of left and right vertical bars 32 extending vertically and an interlocking connection portion 33 connecting between the lower end portions of the pair of vertical bars 32, an extending portion 34 extending in a direction orthogonal to the vertical bars 32 and connected to the upper end portions of the pair of vertical bars 32, and arm portions 35 provided at both end portions of the extending portion 34. The extending portion 34 is provided so as to protrude laterally from the pair of left and right vertical bars 32. As shown in FIG. 4 and the like, the extending portion 34 of the present embodiment is slightly longer than the distance between the upper side portions of the pair of long side side wall portions 13 and slightly shorter than the distance between the vertical wall portions 18 of the overhanging portion 15 corresponding to the pair of long side side wall portions 13.

[0023] Further, each arm portion 35 protrudes from the end portion of the extending portion 34 in a direction intersecting the extending direction of the extending portion 34 and also intersecting the extending direction of the lifting base portion 31. Although details will be described later, each arm portion 35 is a portion for contacting the corresponding lid member 4 according to the displacement of the interlocking member 6 and applying a force toward the open position side and the closed position side to the lid member 4. Note that the interlocking member 6 of the present embodiment is integrally formed by appropriately bending a metal rod-shaped body having a substantially circular cross-sectional shape.

[0024] On the other hand, as shown in FIGS. 2, 4, 5, etc., on the back side side wall portion 14b, the lifting base portion 31 of the interlocking member 6 is arranged on the outer surface side of the container body 2, and the lifting base portion 31 is not protruded outward from the outer peripheral surface of the container body 2. An interlocking accommodation portion 37 is formed by recessing the central portion in the lateral width direction of the back side side wall portion 14b inward of the container body 2. Further, in the lower stage wall portion 17 (above the interlocking accommodation portion 37) of the overhanging portion 15 corresponding to the back side side wall portion 14b, an insertion hole 38 is provided which penetrates vertically and allows the lifting base portion 31 to be inserted therethrough and positions the lifting base portion 31 in the horizontal direction. The width of the insertion hole 38 in the lateral width direction of the back side side wall portion 14b is slightly wider than the lateral width of the lifting base portion 31, and the width of the insertion hole 38 in the thickness direction of the back side side wall portion 14b is slightly wider than the diameter of the vertical bar 32.

[0025] Then, by inserting the elevating base portion 31 of the interlocking member 6 into the insertion hole 38 from above the container body 2, the interlocking member 6 is attached to the container body 2. In the present embodiment, the interlocking member 6 is attached to the container body 2 with the arm portion 35 protruding outward from the extending portion 34 toward the outside of the container body 2. Further, in the attached state of the interlocking member 6, the elevating base portion 31 is accommodated in the interlocking accommodation portion 37, and the extending portion 34 is accommodated inside the container body 2.

[0026] As shown in FIG. 11 and the like, the pedal 5 includes a substantially rectangular parallelepiped operation portion 41 and a substantially rectangular parallelepiped pedal main body 42 connected to the central portion of one long side portion of the operation portion 41, and has a substantially T-shaped configuration in plan view. Further, the operation portion 41 and the pedal main body 42 are open downward, and reinforcing ribs 43 are provided inside thereof. In addition, at the end of the pedal main body 42 on the side not connected to the operation portion 41, a pedal connection portion 44 having a substantially C-shaped cross section opening upward is provided. Further, at an intermediate position in the longitudinal width direction of the pedal main body 42, substantially cylindrical pedal shaft portions 45 protruding laterally from the side surfaces on each long side portion side of the pedal main body 42 are provided. Note that the pedal 5 of the present embodiment is integrally formed of polypropylene.

[0027] On the other hand, as shown in FIG. 2 and the like, a pedal accommodation portion 46 for accommodating the pedal 5 is provided on the lower surface side of the bottom wall component 12 of the container body 2. The pedal accommodation portion 46 extends along the longitudinal width direction of the container body 2 at the central portion in the short width direction of the container body 2, and includes a communication portion 47 for accommodating the pedal main body 42 of the pedal 5, an operation accommodation portion 48 for accommodating the operation portion 41 of the pedal 5, and a connection accommodation portion 49 for accommodating the pedal connection portion 44.

[0028] As shown in Fig. 1 and the like, the operation part 41 of the pedal 5 is arranged on the side of the front side wall part 14a, and the operation accommodation part 48 is also provided on the side of the front side wall part 14a. Further, the part of the front side wall part 14a corresponding to the upper part of the operation accommodation part 48 is formed in a shape recessed inside the container body 2. In particular, the lower part is formed in a shape that is recessed relatively largely so that the tip of the foot can be stepped on the upper surface side of the operation part 41. In addition, as shown in Fig. 2, pedal shaft holes 50 for rotatably supporting the pedal shaft part 45 are provided on the left and right side wall parts of the communication part 47. Then, by fitting the pedal shaft part 45 of the pedal 5 into the pedal shaft hole 50, the pedal 5 is rotatably attached to the container body 2 on the lower surface side of the bottom wall forming part 12. Incidentally, the pedal 5 of the present embodiment is configured so that when it is attached to the container body 2, its entire body is accommodated in the pedal accommodation part 46, and the pedal 5 does not protrude outward from the outer peripheral surface of the container body 2.

[0029] Furthermore, as shown in Fig. 2, the connection accommodation part 49 is a part that also serves as the lower part of the interlocking accommodation part 37, and is a part for positioning the pedal connection part 44 below the interlocking member 6 accommodated in the interlocking accommodation part 37. Then, by fitting the interlocking connection part 33 having a circular cross-section corresponding to the lower end part of the interlocking member 6 inside the pedal connection part 44 having a substantially C-shaped cross-section, the interlocking member 6 (interlocking connection part 33) and the pedal 5 (pedal connection part 44) are rotatably connected. Thereby, the interlocking member 6 is displaced up and down according to the operation of the pedal 5.

[0030] That is, as shown in Figs. 1 and 2, when no operation is performed (stepping) on the operation part 41 of the pedal 5, due to the weight of the interlocking member 6, within the range where it can rotate and displace around the pedal shaft part 45, the pedal connection part 44 side (rear end part side) is lowered, and the operation part 41 side (front end part side) is maintained in an upward posture. Further, when no operation is performed on the operation part 41 of the pedal 5, the extending part 34 and the arm part 35 of the interlocking member 6 are accommodated inside the container body 2 (see Fig. 16).

[0031] On the other hand, as shown in FIG. 3, when an operation is performed on the operation unit 41, the pedal 5 assumes a posture in which the operation unit 41 side (front end side) descends and the pedal connection part 44 side (rear end side) ascends, and the interlocking member 6 is displaced upward. Further, although details will be described later, in a state where an operation is performed on the operation unit 41 of the pedal 5, the extending part 34 and the arm part 35 of the interlocking member 6 protrude above the container body 2 (see FIG. 22).

[0032] In addition, since the interlocking member 6 is connected to the pedal 5, the elevating base part 31 of the interlocking member 6 is provided along the back side wall part 14b of the container body 2 and abuts or is close to the outer surface of the back side wall part 14b. Further, as described above, since the interlocking member 6 is provided on the outer surface side of the container body 2, a situation where the interlocking member 6 and the contents of the container body 2 interfere with each other, the elevating operation of the interlocking member 6 is inhibited, or the contents are adversely affected is avoided. Also, the connection between the interlocking member 6 and the pedal 5 can be performed relatively easily outside the container body 2.

[0033] In addition, as shown in FIGS. 3 and 4, etc., the trash can 1 of the present embodiment includes a pair of bag fixing members 53 for holding the upper part of a bag (trash bag) mounted inside the container body 2. As shown in FIG. 12, the bag fixing member 53 includes a substantially U-shaped bag fixing body 54 and bag fixing shaft parts 55 that protrude outward at both end parts of the bag fixing body 54. The bag fixing shaft part 55 has a columnar shape and has a diameter-expanded part on the tip side.

[0034] On the other hand, as shown in FIG. 5, in the container body 2, a pair of bag fixing shaft holes 56 are provided at positions near the center in the lateral width direction of the long side side wall part 13 with respect to the vertical wall part 18 of the protruding part 15 corresponding to each long side side wall part 13. Then, with the bag fixing body 54 arranged along the inner side of the upper edge part of the container body 2, the bag fixing member 53 is rotatably attached to the container body 2 by fitting the bag fixing shaft part 55 into the bag fixing shaft hole 56.

[0035] Still, the bag stopper body 54 basically includes a portion supported by the lower wall portion 17 of the protruding portion 15 and a portion fitted inside the accommodating portion 11, and has a substantially L-shaped cross section (see FIGS. 12 and 22). Further, both ends of the bag stopper body 54 protrude upward so that the bag stopper shaft portion 55 is positioned above the lower wall portion 17 (see FIGS. 3 and 12). Furthermore, as shown in FIG. 4, the pair of bag stopper members 53 have the same shape as each other. In addition, regarding the bag stopper member 53 provided on the side of the back side side wall portion 14b among the pair of bag stopper members 53, due to the fact that the back side side wall portion 14b is concave and convex in the inner and outer circumferential directions of the container body 2, although it is not supported by the lower wall portion 17 on both side portions in the width direction of the back side side wall portion 14b, it is supported by a portion of the lower wall portion 17 adjacent to the insertion hole 38 near the central portion in the width direction of the back side side wall portion 14b.

[0036] Now, as shown in FIGS. 4, 9, 10, 21, etc., each arm portion 35 of the interlocking member 6 of the present embodiment includes a first arm 61 that protrudes from the end portion of the extending portion 34, is substantially orthogonal to the extending portion 34, and protrudes in a substantially horizontal direction, and a second arm 62 provided so as to protrude upward from the tip end portion of the first arm 61. The first arm 61 of the present embodiment protrudes outward from the container body 2 (to the side opposite to the central portion side in the width direction of each long side side wall portion 13) from the extending portion 34 extending along the width direction of the back side side wall portion 14b in the state where the interlocking member 6 is attached to the container body 2, and extends in a direction along the rotation shaft 24 of the lid member 4 (parallel to the rotation shaft 24 of the lid member 4) (see FIGS. 4, 6, and 17). Furthermore, the second arm 62 includes a first hanging portion 63 that extends upward from the tip end portion of the first arm 61, and a second hanging portion 64 that extends from the tip end portion of the first hanging portion 63, is orthogonal to the first hanging portion 63, and extends toward the central portion side in the width direction of each short side side wall portion 14, and has a substantially L shape.

[0037] In contrast, as shown in FIGS. 3, 4, 7, etc., the lid member 4 has a rear surface side protruding piece portion 65 that protrudes from a portion on the side wall portion 14b on the rear surface side of the container body 2 and on the rotation axis 24 side rather than the central portion in the short side width direction of the lid member 4 among the lower surfaces when in the closed position. As shown in FIGS. 8, 16, 18, 21, etc., the rear surface side protruding piece portion 65 has a locking hole 66 that penetrates vertically when the lid member 4 is in the open position when the pedal 5 is operated, and penetrates in the lateral width direction of the short side wall portion 14 when the lid member 4 is in the closed position. By providing the locking hole 66, the rear surface side protruding piece portion 65 is composed of a pair of outer piece portions 67 arranged along the lateral width direction (rotation axis 24 direction) of the lid member 4, an inner piece portion 68, and a tip side piece portion 69 that connects between the tip end portion of the outer piece portion 67 and the tip end portion of the inner piece portion 68 (see FIGS. 8 and 18). In addition, the outer piece portion 67 of the present embodiment is connected to the inner surface of the frame wall portion 22 corresponding to the short side portion of the lid member 4.

[0038] Also, as shown in FIGS. 8, 18, etc., the lid member 4 includes an auxiliary piece portion 70 that connects between the inner piece portion 68 and the portion of the frame wall portion 22 on the rotation axis 24 side of the lid member 4. The auxiliary piece portion 70 extends parallel to the short side portion of the lid member 4 (see FIG. 17). Further, the protruding length of the rear surface side protruding piece portion 65 from the top wall portion 21 is longer than the protruding length of the frame wall portion 22 from the top wall portion 21, and the protruding length of the auxiliary piece portion 70 from the top wall portion 21 is substantially the same as the protruding length of the frame wall portion 22 from the top wall portion 21 and shorter than the protruding length of the rear surface side protruding piece portion 65 from the top wall portion 21. In the present embodiment, the distance between the auxiliary piece portion 70 and the tip side piece portion 69 of the rear surface side protruding piece portion 65 is slightly longer than the width of the second arm 62 in the lateral width direction of the rear surface side wall portion 14b.

[0039] In addition, as shown in FIG. 18, etc., in the container body 2, at both ends of the overhanging portion 15 corresponding to the rear surface side wall portion 14b, the vertical wall portion 18 and the upper stage wall portion 19 are omitted (the edge wall portion 16 extends directly from the lower stage wall portion 17), and a protruding piece accommodating recess 71 for accommodating the rear surface side protruding piece portion 65 is provided when the lid member 4 is in the closed position.

[0040] Here, the interlocking mode between the interlocking member 6 and the lid member 4 will be described. As shown in FIGS. 13, 14, 16, and 17, when the lid member 4 is in the closed position, the rear surface side protruding piece portion 65 and the second arm 62 are relatively arranged at positions displaced in the horizontal direction (in this example, the lateral width direction of the rear surface side wall portion 14b). In the present embodiment, the rear surface side protruding piece portion 65 is arranged adjacent to the central portion side in the lateral width direction of the rear surface side wall portion 14b of the second arm 62. Further, as shown in FIG. 15, the upper surface of the first arm 61 is in contact with or adjacent to the lower side portion of the auxiliary piece portion 70.

[0041] Next, when the pedal 5 is operated (the operation portion 41 is stepped on) and the interlocking member 6 is displaced upward from the state where the lid member 4 is in the closed position, as shown in FIGS. 18 and 19, the auxiliary piece portion 70 of the lid member 4 comes into contact with the first arm 61 of the interlocking member 6, and an external force directed toward the open position side is applied from the first arm 61. As a result, the lid member 4 rotates and displaces upward. Further, in the present embodiment, in the process where the interlocking member 6 is displaced upward and the lid member 4 is set to the open position, after the auxiliary piece portion 70 is pressed upward and outward of the container body 2 by the first arm 61, the inner piece portion 68 of the rear surface side protruding piece portion 65 comes into contact with the upper surface side of the first arm 61 and is pressed upward, so that the lid member 4 is set to the open position extending substantially vertically upward from the rotation shaft 24. Of course, when the pedal 5 is operated, the pair of lid members 4 are synchronously displaced to the open position.

[0042] Also, as shown in FIG. 20 and the like, in the present embodiment, when the lid member 4 is set to the open position by operating the pedal 5, the second hanging portion 64 of the second arm 62 and the upper portion of the first hanging portion 63 are inserted into the locking hole 66 of the rear surface side protruding piece portion 65. Then, as shown in FIGS. 21 to 24, when the lid member 4 is completely set to the open position, the first hanging portion 63 penetrates the locking hole 66, and the second hanging portion 64 is arranged to face (in this example, in contact with or adjacent to) the upper surface side of the tip side piece portion 69.

[0043] As shown in FIGS. 17, 24, etc., the auxiliary piece portion 70 and the back surface side projecting piece portion 65 (inner piece portion 68) extend in a direction orthogonal to the rotation axis 24 of the lid member 4. On the other hand, the first arm 61 extends parallel to the rotation axis 24 of the lid member 4 (furthermore, the second arm 62 is configured to be insertable into the locking hole 66). For this reason, when the lid member 4 is in the open position, the first arm 61 is prevented from coming off from the auxiliary piece portion 70 and the back surface side projecting piece portion 65 (inner piece portion 68) during sliding with them, and a stable sliding operation is ensured. In addition, as shown in FIGS. 8, 19, 21, etc., for the portion of the auxiliary piece portion 70 that can contact the first arm 61, the protruding length from the top wall portion 21 is shorter than that of other portions, and both ends thereof are configured in an arc shape. Thereby, while suppressing the protruding length of the back surface side projecting piece portion 65, a locking hole 66 that allows the second arm 62 to be inserted into the back surface side projecting piece portion 65 can be formed, and the sliding of the first arm 61 from the auxiliary piece portion 70 to the back surface side projecting piece portion 65 (inner piece portion 68) when the lid member 4 is opened becomes relatively smooth.

[0044] Subsequently, when the operation on the pedal 5 is released (the foot is removed from the pedal 5) from the state where the pedal 5 is operated and the lid member 4 is in the open position as shown in FIGS. 21 to 23, and the interlocking member 6 is displaced downward, the lower surface of the second hanging portion 64 of the second arm 62 of the arm portion 35 of the interlocking member 6 contacts the surface of the tip side piece portion 69 of the back surface side projecting piece portion 65 that faces upward. As a result, an external force directed toward the closed position side is applied to the lid member 4 (tip side piece portion 69) from the interlocking member 6 (second hanging portion 64), and the lid member 4 is tilted and displaced toward the closed position based on such an external force (see FIG. 18, etc.). When the lid member 4 that was in the open position tilts toward the closed position to a certain extent, the lid member 4 is displaced to the closed position by its own weight. Of course, when the operation on the pedal 5 is released, the pair of lid members 4 are synchronously displaced to the closed position.

[0045] In addition, as shown in FIGS. 18, 20, etc., when the pedal 5 is operated and the lid member 4 is displaced from the open position toward the closed position, the insertion state of the second arm 62 into the locking hole 66 is released (the second arm 62 comes out of the locking hole 66). When the lid member 4 is in the closed position, as described above (as shown in FIGS. 14, 16, and 17), the rear surface side protruding piece portion 65 and the second arm 62 are relatively arranged at positions shifted in the horizontal direction.

[0046] In this embodiment, an opening contact portion is formed by the lower side portion of the auxiliary piece portion 70 when the lid member 4 is in the closed position and the inner piece portion 68 of the rear surface side protruding piece portion 65 (particularly, the lower side portion when the lid member 4 is in the open position). Further, an opening acting portion is formed by the first arm 61 (particularly, the upper surface). Also, a closing contact portion is formed by the tip side piece portion 69 of the rear surface side protruding piece portion 65 (particularly, the upper surface when the lid member 4 is in the open position). Further, a closing acting portion is formed by the second arm 62 (particularly, the lower surface of the second hanging portion 64).

[0047] Also, in this embodiment, when the lid member 4 in the closed position is displaced to the open position without operating the pedal 5, the lid member 4 and the interlocking member 6 are configured not to interfere with each other. That is, when the pedal 5 is not operated, the second arm 62 (second hanging portion 64) of the arm portion 35 of the interlocking member 6 located below is arranged at a position outside the orbit of the rear surface side protruding piece portion 65 of the lid member 4 that is displaced between the open position and the closed position. For this reason, the lid member 4 can be displaced to the open position without directly touching the lid member 4 or the like and without interlocking the interlocking member 6.

[0048] Furthermore, as shown in Fig. 25, the trash can 1 of the present embodiment can be stacked vertically (nested) by placing the lid member 4 in the open position without operating the pedal 5 (without displacing the interlocking member 6 upward) as described above, so that the lower part of the upper trash can 1 (container body 2) is accommodated inside the lower trash can 1 (container body 2). Incidentally, as shown in Fig. 26, the trash can 1 is in a form in which the bag fixing member 53 is not attached (in Fig. 26, only the interlocking member 6 and the pedal 5 are attached to the container body 2), and by nesting, storage and the like can be performed more efficiently.

[0049] Also, as shown in Fig. 27, the trash cans 1 of the present embodiment are configured to be connectable to each other side by side. That is, as shown in Fig. 2, a side-by-side connecting portion 73 is provided on the outer surface side of one long side wall portion 13 of the container body 2. Further, as shown in Fig. 1 and the like, a side-by-side connected portion 74 to be connected to the side-by-side connecting portion 73 is provided on the outer surface side of the other long side wall portion 13. The side-by-side connecting portion 73 and the side-by-side connected portion 74 are configured to be detachable by relative displacement in the vertical direction, and in the connected state, relative displacement in the horizontal direction between the connected trash cans 1 is prevented.

[0050] As described in detail above, according to the present embodiment, in the state where the lid member 4 is in the closed position, the rear surface side protruding piece portion 65 and the second arm 62 are relatively arranged at positions shifted in the horizontal direction. Therefore, in the state where the lid member 4 is in the closed position, it is possible to configure such that the interlocking member 6 including the second arm 62 (such as the second hanging portion 64) is not opposed to the upper surface side of the rear surface side protruding piece portion 65 (such as the tip side piece portion 69). With this configuration, for example, when removing the lid member 4 in the closed position from the container body 2, a situation where the lid member 4 is caught by the interlocking member 6 can be avoided. Further, when attaching the lid member 4 to the container body 2 to which the interlocking member 6 is attached, a situation where the attachment of the lid member 4 is hindered by the interlocking member 6 can be avoided.

[0051] On the other hand, when the lid member 4 is in the open position by operating the pedal 5, since the second engaging portion 64 of the second arm 62 is disposed to face the upper surface side of the distal end side piece portion 69 of the back surface side protruding piece portion 65, even if the lid member 4 and the interlocking member 6 are not connected, when the operation of the pedal 5 is canceled (when the interlocking member 6 is displaced downward), the second engaging portion 64 of the second arm 62 abuts against the distal end side piece portion 69 of the back surface side protruding piece portion 65, and an external force toward the closed position side is applied to the lid member 4, thereby establishing an interlocking mechanism among the pedal 5, the interlocking member 6, and the lid member 4. Therefore, in the assembly work of the trash can 1, with respect to the lid member 4, it is only necessary to simply attach it to the container body 2 (fit the shaft portion 23 of the lid member 4 into the shaft hole 25 of the container body 2) to be in a state interlocked with the operation of the pedal 5. For example, compared with a configuration that requires not only attaching the lid member 4 to the container body 2 but also connecting it to the interlocking member 6, the assembly workability of the trash can 1 can be improved. Also, the workability can be improved when it is necessary to remove the lid member 4 from the container body 2.

[0052] Furthermore, in a state where the lid member 4 is in the open position by operating the pedal 5, even if the lid member 4 is pulled upward or the like and is about to be displaced in a direction away from the container body 2, the second engaging portion 64 of the second arm 62 abuts against the distal end side piece portion 69 of the back surface side protruding piece portion 65, thereby restricting such displacement. Therefore, for example, by operating the pedal 5 forcefully, it is possible to prevent the lid member 4 from accidentally falling off, such as the lid member 4 being forcefully opened to the open position and then coming off from the container body 2.

[0053] Further, in the present embodiment, when the lid member 4 in the closed position is displaced to the open position without operating the pedal 5, the lid member 4 and the interlocking member 6 are prevented from interfering with each other. For this reason, when directly touching the lid member 4 in the closed position and displacing it to the open position without operating the pedal 5, a situation where the lid member 4 gets caught on the interlocking member 6 or the interlocking member 6 is lifted in conjunction with the lid member 4 is avoided. Thus, the lid member 4 can be displaced to the open position relatively easily. Therefore, it is possible to improve the operability when directly touching the lid member 4 to set it to the open position.

[0054] Also, in the present embodiment, the second arm 62 is composed of a first hanging portion 63 that protrudes upward from the tip of the first arm 61 and a second hanging portion 64 that protrudes from the tip of the first hanging portion 63 toward the central portion side in the longitudinal width direction of the extending portion 34. In a state where the lid member 4 is set to the open position by operating the pedal 5, the first hanging portion 63 is inserted into the locking hole 66 of the back surface side protruding piece portion 65, and the lower surface side of the second hanging portion 64 and the upper surface side of the tip side piece portion 69 are arranged to face each other. That is, in a state where the lid member 4 is set to the open position by operating the pedal 5, the second hanging portion 64 of the second arm 62 and the first arm 61 are arranged vertically, and between the second hanging portion 64 and the first arm 61, a part of the tip side piece portion 69 and a part of the inner piece portion 68 of the back surface side protruding piece portion 65 are arranged. With this configuration, the configurations of the portions (the first arm 61 and the second hanging portion 64) that apply forces to the lid member 4 of the interlocking member 6 in the open position side and the closed position side, and the portion (the back surface side protruding piece portion 65) that receives forces from the interlocking member 6 in the open position side and the closed position side can be made as compact as possible.

[0055] Furthermore, the first arm 61 of the interlocking member 6 extends in a direction along the rotation axis 24 of the lid member 4 (substantially parallel to the rotation axis 24). Therefore, the range within which the auxiliary piece portion 70 and the inner piece portion 68 of the back surface side protruding piece portion 65 of the first arm 61 can come into contact can be increased (contact is made along a line rather than at a point), and when the pedal 5 is operated to bring the lid member 4 to the open position, the first arm 61 can be surely brought into contact with the auxiliary piece portion 70 and the inner piece portion 68. Further, for example, when the first arm 61 extends orthogonally to the rotation axis 24 of the lid member 4, when the lid member 4 is brought to the open position, the sliding contact state between the first arm 61, the auxiliary piece portion 70, and the inner piece portion 68 is eliminated just by a slight displacement, or when the first arm 61 is inclined relatively greatly with respect to the rotation axis 24, when the lid member 4 is brought to the open position, a situation where the lid member 4 is rotated and displaced in a state of being biased to one side or the other side in the direction along the rotation axis 24 and it becomes difficult to rotate can be avoided. Therefore, the operability when the pedal 5 is operated to bring the lid member 4 to the open position can be improved. In particular, when the contact area between the auxiliary piece portion 70 and the inner piece portion 68 of the first arm 61 increases, damage to the first arm 61, the auxiliary piece portion 70, and the inner piece portion 68 can be more surely suppressed.

[0056] In addition, the elevating base portion 31 of the interlocking member 6 is provided along the back surface side wall portion 14b of the container body 2 and is arranged so as to contact or be close to the outer surface of the back surface side wall portion 14b. Further, the arm portion 35 protrudes outward from the container body 2 from the tip of the extending portion 34. Therefore, a situation where the volume of the container body 2 is reduced by the interlocking member 6 can be suppressed as much as possible. Also, for example, when stacking (nesting) trash cans 1 with the lid member 4 in the open position, or when nesting the container bodies 2 in a state where the interlocking member 6 is mounted and the lid member 4 is not mounted, the interlocking member 6 can be made to not hinder nesting as much as possible, and the nesting efficiency, and thus the transportation and storage efficiency of the trash can 1 (container body 2) can be improved.

[0057] Also, a pair of lid members 4 are provided, the elevating base portion 31 of the interlocking member 6 extends vertically at a position between the pair of lid members 4, and the extending portion 34 is provided so as to extend to a position near each rotation axis 24 of the pair of lid members 4. Therefore, the pair of lid members 4 can be simultaneously opened and closed by one interlocking member 6, and simplification of the configuration of the interlocking member 6 and the like can be achieved. Further, since the elevating base portion 31 is provided at a position between the pair of lid members 4, when the lid members 4 are provided in a pair, the interlocking member 6 can be arranged in a well-balanced manner while simplifying the structure of the interlocking member 6. Furthermore, since the extending portion 34 extends to a position near the rotation axis 24 of the lid member 4, the arm portions 35 (the first arm 61 and the second arm 62) provided at the tip end portion of the extending portion 34 also come into contact with the back surface side protruding piece portion 65 and the auxiliary piece portion 70 at a position near the rotation axis 24 of the lid member 4. Therefore, the stroke amount of the interlocking member 6 when the lid member 4 is opened and closed can be minimized as much as possible, and improvement in the operability of the pedal 5 and the like (reduction in the stroke amount of the pedal 5 when the lid member 4 is in the open position, improvement in the reaction speed at which the lid member 4 is opened and closed in response to the operation of the pedal 5, etc.) can be achieved.

[0058] In addition, the back surface side protruding piece portion 65 is provided with a locking hole 66 through which the second arm 62 is inserted in a state where the pedal 5 is operated and the lid member 4 is in the open position. Therefore, interference between the second arm 62 (the second hanging portion 64) and the back surface side protruding piece portion 65 (the tip side piece portion 69) when the lid member 4 is brought into the open position by operating the pedal 5 can be efficiently avoided, and after canceling the operation of the pedal 5 in a state where the lid member 4 is in the open position by operating the pedal 5, the second hanging portion 64 comes into contact with the tip side piece portion 69, and shortening of the time until the lid member 4 is displaced to the closed position side (improvement in the reaction speed of the lid member 4) and the like can be achieved. Therefore, improvement in the opening and closing operability of the lid member 4 by the pedal 5 and the like can be achieved.

[0059] Note that the present invention is not limited to the description of the above embodiment, and for example, it may be implemented as follows. Of course, other application examples and modification examples not illustrated below are also naturally possible.

[0060] (a) In the above embodiment, the arm portion 35 (the first arm 61) protrudes outward from the container body 2 orthogonally to the extending portion 34 from the end of the extending portion 34. However, it may protrude inward from the end of the extending portion 34 orthogonally to the extending portion 34 and into the container body 2. However, as in the above embodiment, by protruding the arm portion 35 (the first arm 61) outward from the end of the extending portion 34 orthogonally to the extending portion 34 and into the container body 2, the arm portion 35, the back surface side protruding piece portion 65, and the auxiliary piece portion 70 can be arranged outside the accommodating portion 11. Thereby, when the lid member 4 is in the closed position, it is possible to avoid the arm portion 35, the back surface side protruding piece portion 65, and the auxiliary piece portion 70 from interfering with the contents. Also, when nesting the trash cans 1 with the lid member 4 in the open position without operating the pedal 5, it is possible to avoid the back surface side protruding piece portion 65 of the lower trash can 1 from interfering with the upper trash can 1.

[0061] Also, in the above embodiment, the first arm 61 extends parallel to the rotation axis 24 of the lid member 4. However, it is not particularly limited to such a configuration. When the interlocking member 6 rises in response to the operation of the pedal 5, it is only necessary to be configured so that the auxiliary piece portion 70 of the lid member 4 and the inner piece portion 68 can come into contact with each other to apply an external force toward the open position side to the lid member 4. Furthermore, the cross-sectional shape of the first arm 61 is not particularly limited and can be changed as appropriate. However, among the first arm 61, the portion that can come into contact with the auxiliary piece portion 70 and the inner piece portion 68 is formed of a curved surface, and the first arm 61 is configured to extend parallel to the rotation axis 24 of the lid member 4, so that the lid member 4 can be rotated and displaced more smoothly.

[0062] In addition, the shape of the second arm 62 is not particularly limited, and when the operation of the pedal 5 is canceled and the interlocking member 6 descends, it can contact the tip-side piece portion 69 of the lid member 4 and apply an external force toward the closed position side to the lid member 4 (in a state where the lid member 4 is in the open position when the pedal 5 is operated, the second arm is configured to be disposed opposite the upper surface side of the back surface-side protruding piece portion 65). For example, the second arm 62 may be configured to extend obliquely upward from the tip of the first arm 61 toward the center side of the extending portion 34.

[0063] Furthermore, the shape of the portion of the lid member 4 that contacts the arm portion 35 and to which an external force for moving to the open position side or the closed position side is applied is not particularly limited. For example, the auxiliary piece portion 70 may be omitted, and when the pedal 5 is operated, the arm portion 35 may contact the lower surface of the top wall portion 21 of the lid member 4 so that the lid member 4 is displaced to the open position side.

[0064] (b) In the above embodiment, in a state where the lid member 4 is in the open position when the pedal 5 is operated, the second engaging portion 64 of the interlocking member 6 and the first arm 61 are arranged vertically, and the back surface-side protruding piece portion 65 (the tip-side piece portion 69 and the inner piece portion 68) is arranged between the second engaging portion 64 and the first arm 61. However, it is not particularly limited to such a configuration. When the lid member 4 opens and closes in conjunction with the operation of the pedal 5, and when the lid member 4 in the closed position is lifted (for example, displaced to the open position side) without operating the pedal 5, it is only necessary to configure the lid member 4 so that the interlocking member 6 is not caught.

[0065] For example, the lid member 82 of the trash can 81 shown in FIGS. 28 and 29 projects downward from the lower surface of the lid member 82 in the closed position (instead of the rear side projecting piece portion 65 and the auxiliary piece portion 70 of the above-described embodiment), and in a state where the lid member 82 is in the open position, a first projecting piece portion 83 and a second projecting piece portion 84 that are vertically spaced apart from each other, and an auxiliary piece portion 85 that connects the side portions on the center side in the lateral width direction of the lid member 4 between the first projecting piece portion 83 and the second projecting piece portion 84 are provided. Further, the arm portion 87 of the interlocking member 86 is composed of a first arm 89 that projects outward orthogonally to the extending portion 88 from both ends of the extending portion 88 (extending parallel to the rotation axis of the lid member 82), and a second arm 90 that projects downward from the tip of the first arm 89. Also, in a state where the lid member 82 is in the open position when a pedal operation is performed, the lower end portion of the second arm 90 is disposed to face the upper surface side of the second projecting piece portion 84 (the first arm 89 and the second arm 90 are disposed between the first projecting piece portion 83 and the second projecting piece portion 84).

[0066] When the lid member 82 is in the closed position, the upper surface side of the first arm 89 and the lower side portion of the auxiliary piece portion 85 are disposed to face each other (in this example, to be in contact or close proximity). Then, as shown in FIG. 29, when a pedal operation is performed and the interlocking member 86 is displaced upward, the auxiliary piece portion 85 is pressed upward by the first arm 89, and the lid member 82 is displaced toward the open position side. Thereafter, the first arm 89 that was in sliding contact with the auxiliary piece portion 85 comes into sliding contact with the lower surface side of the first projecting piece portion 83, and after the first projecting piece portion 83 is pressed upward by the first arm 89, the lid member 82 is set to the open position. Incidentally, a hole portion 91 for avoiding interference with the second arm 90 is provided in the second projecting piece portion 84 when the lid member 82 rotates and displaces.

[0067] As shown in Fig. 28, in the state where the lid member 82 is in the open position by pedal operation, as described above, the second arm 90 is arranged to face the upper surface side of the second protruding piece portion 84. Further, when the pedal operation is canceled from the state where the pedal operation is performed and the lid member 82 is in the open position, as the interlocking member 86 is displaced downward, the lower end portion of the second arm 90 abuts on the upper surface of the second protruding piece portion 84, whereby an external force toward the closed position side is applied to the lid member 82. When the lid member 82 in the open position is tilted to a certain extent toward the closed position side, the lid member 82 is displaced to the closed position by its own weight.

[0068] Further, in the state where the lid member 82 is in the closed position, the second protruding piece portion 84 (and the first protruding piece portion 83) and the arm portion 87 are arranged relative to each other at positions shifted in the horizontal direction. That is, in the state where the lid member 82 is in the closed position, the interlocking member 86 including the arm portion 87 is configured not to face the upper surface side of the second protruding piece portion 84. In this exemplary embodiment, the first arm 89 corresponds to the opening action portion, the second arm 90 corresponds to the closing action portion, the auxiliary piece portion 85 and the first protruding piece portion 83 correspond to the opening abutting portion, and the second protruding piece portion 84 corresponds to the closing abutting portion.

[0069] Even when the above configuration is adopted, as in the above-described embodiment, when the pedal operation is performed, the lid member 82 can be interlocked with the pedal operation, and when the lid member 82 is lifted without performing the pedal operation (for example, when it is displaced to the open position side), the interlocking member 86 can be configured not to catch on the lid member 82. As a result, it is possible to improve the assembly workability of the trash can 81 and the like.

[0070] Furthermore, the shapes of the arm portion 87, the first protruding piece portion 83, and the second protruding piece portion 84 are not particularly limited. As shown in FIGS. 30 and 31, the second arm 90 is omitted from the arm portion 87, and when the pedal operation is canceled and the lid member 82 is in the closed position, the lower surface side of the first arm 89 abuts against the upper surface side of the second protruding piece portion 84, so that an external force toward the closed position side is applied to the lid member 82. Also, when adopting this configuration, the hole portion 91 of the second protruding piece portion 84 can be omitted. Incidentally, by providing the second arm 90, in a state where the pedal operation is performed and the lid member 82 is in the open position, the gap between the arm portion 87 and the second protruding piece portion 84 can be minimized as much as possible, and the time from canceling the pedal operation until the lid member 82 starts to close can be shortened. Note that, instead of protruding the first arm 89 outward from the container body 92 orthogonally to the extending portion 88, it is also possible to protrude it inward from the container body 92 orthogonally to the extending portion 88.

[0071] Also, on the lid member 82 of the trash can 81 shown in FIGS. 28 and 29 (FIGS. 30 and 31), among the frame wall portions 94 protruding downward from the outer peripheral edge of the top wall portion 93 of the lid member 82, at the side portion (particularly, the portion on the open end side of the lid member 82) extending orthogonally to the rotation axis direction of the lid member 82, it is formed in a concave shape so that a fingertip can be inserted between the side portion of the lid member 82 in the closed position and the container body 92, and a handle portion 95 is provided so that a fingertip can be placed on the side portion of the lid member 82. By providing the handle portion 95, it is easier to perform a direct opening and closing operation on the lid member 82, such as directly placing a hand on the lid member 82 in the closed position and displacing it to the open position side. Note that the shape of the handle portion 95 is not particularly limited, and for example, it may be configured in a substantially hook-shaped cross section or the like that is easy to hang on a fingertip.

[0072] (c) In the above embodiment, a pair of lid members 4 are provided, but the opening 3 of the container body 2 may be configured to be opened and closed by a single lid member. However, by configuring the opening 3 of the container body 2 to be opened and closed by a pair of lid members 4, it is possible to reduce the burden on the mechanism for interlocking the lid member 4 and the interlocking member 6, shorten the time required for opening and closing the trash can 1, and the like. Further, in the above embodiment, the lid member 4 is mounted corresponding to the long-side side wall portion 13 (such that the rotation axis 24 extends along the width direction of the long-side side wall portion 13), but it may be mounted corresponding to the short-side side wall portion 14.

[0073] Furthermore, in the above embodiment, the interlocking member 6 is mounted corresponding to the short-side side wall portion 14 (the back-side side wall portion 14b) instead of the long-side side wall portion 13 to which the lid member 4 is mounted, but it may be mounted on the same side wall portion as the side wall portion to which the lid member 4 is mounted (particularly, when there is only one lid member 4 mounted on the container body 2). In this case, the arm portion may be provided such that, for example, the first arm as the opening action portion extends the extension portion 34 (constituted by both ends of the extension portion 34), and the second arm includes a first hanging portion extending upward from the tip of the first arm and a second hanging portion as the closing action portion extending horizontally from the tip of the first hanging portion and substantially orthogonal to the first arm. In addition, in the above embodiment, the container body 2 has a square box shape, but the shape of the container body 2 is not particularly limited and may be configured, for example, in a substantially cylindrical shape.

[0074] Also, in the above embodiment, the shapes of the pair of lid members 4 are different (the formation positions of the back-side protruding piece portion 65 and the auxiliary piece portion 70 are different), but they may have the same shape (by providing a pair of back-side protruding piece portions 65 and auxiliary piece portions 70 respectively to form a symmetric shape). In this case, the lid members 4 can be made common, and it is possible to improve workability and convenience in inventory management and the like.

[0075] In addition, in the above-described embodiment, the lid member 4 is provided with the protruding shaft portion 23, and the container body 2 is provided with the shaft hole 25. However, a configuration may be adopted in which the container body 2 is provided with a shaft portion, and the lid member 4 is provided with a shaft hole or a bottomed shaft hole. Further, by setting the lid member 4 to the open position without operating the pedal 5, a configuration (for example, the shaft hole provided in the lid member 4 has a substantially C-shaped opening downward in a state where the lid member 4 is in the open position, and it is easy to remove the lid member 4 in the open position upward) may be adopted so that the lid member 4 can be easily removed from the container body 2. Incidentally, when the lid member 4 is set to the open position by operating the pedal 5, the second arm 62 of the interlocking member 6 is caught by the rear surface side protruding piece portion 65 (tip side piece portion 69) of the lid member 4, so that the lid member 4 cannot be removed from the container body 2.

[0076] (d) Further, the shape, arrangement, etc. of the interlocking member 6 and the pedal 5 are not particularly limited. For example, the interlocking member 6 may be configured by a plurality of parts that can be relatively displaced with respect to each other. However, in view of workability, cost, etc. related to the manufacture of the trash can 1, it is desirable that the number of parts be as small as possible. Furthermore, the pedal 5 and the interlocking member 6 may be configured to protrude outward from the outer peripheral surface of the container body 2. However, in order to save space in the installation of the trash can 1 and prevent tripping over the pedal 5, it is desirable that the pedal 5 and the interlocking member 6 are configured not to protrude from the outer peripheral surface of the container body 2. Further, as in the above-described embodiment, by forming the portion (up to the upper edge portion of the short-side side wall portion 14 or the vicinity thereof) corresponding to the upper side of the operation accommodation portion 48 in the short-side side wall portion 14 to be recessed inside the container body 2, it is possible to easily confirm the position of the operation portion 41 of the pedal 5 from above, and it is possible to improve the strength of the short-side side wall portion 14.

[0077] In the above-described embodiment, as the operation member that the user operates when opening the trash can 1, it is embodied as the pedal 5 assuming operation with the toe, but it is not particularly limited to such a configuration, and it can also be applied to a handle, a button, etc. assuming operation by hand.

[0078] Furthermore, in the above embodiment, the pair (two sheets) of lid members 4 are configured to be opened and closed by one linkage member 6 and one pedal 5. However, a linkage member and a pedal may be provided corresponding to each lid member 4. For example, a pair of left and right pedals may be provided adjacent to each other on the left and right, and a linkage member that interlocks the left pedal and the left lid member, and a linkage member that interlocks the right pedal and the right lid member may be provided. It may be configured such that when one of the left and right pedals is depressed, one lid member opens, and when both the left and right pedals are depressed, both lid members open. Further, for example, when there are three or more lid members, it may be configured to include a linkage member and a pedal for opening and closing the plurality of lid members at once, and a linkage member and a pedal for opening and closing one lid member different from the plurality of lid members.

[0079] In addition, in the above embodiment, the linkage member 6 has a bilaterally symmetric shape, but it may have an asymmetric shape. For example, in accordance with the pedal 5 being provided at a position shifted to the right of the center in the lateral width direction of the container body 2, the lifting base portion 31 may also be provided at a position shifted to the right from the center in the lateral width direction of the linkage member 6 (the extending lengths of the extending portion 34 extending leftward from the lifting base portion 31 and the extending portion 34 extending rightward being different). Further, for example, in a configuration in which the areas (weights) of one and the other of the pair of lid members 4 are different in plan view, the position of the lifting base portion 31 in the lateral width direction of the linkage member 6 may be set according to the balance of the pair of lid members 4.

[0080] (e) In the above embodiment, the container body 2, the lid member 4, and the pedal 5 are made of polypropylene, but they may be made of other resin materials such as polyethylene, PET, and polyamide. Further, the linkage member 6 is configured by bending a rod-shaped body made of metal, but it can also be configured with a resin material or the like.

[0081] In addition, in the above-described embodiment, the garbage bin 1 is embodied as a container with a lid. However, for example, it can also be used as a storage box for storing and preserving articles other than garbage (such as balls, toys, sundries, materials, etc.). In addition, in the above-described embodiment, the garbage bins 1 with the lid member 4 in the open position or the container bodies 2 with the lid member 4 removed can be nested, or the garbage bins 1 can be simply connected side by side by a locking structure. However, it is also possible to apply it to a garbage bin 1 that cannot perform these operations.
