[0013] An embodiment will be described below with reference to the drawings. As shown in Figures 1 to 3, the trash can 1, as a container with a lid, comprises a roughly box-shaped container body 2 having an opening 3 that opens upward, a pair of lid members 4 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 the user stepping on it with their toes, and an interlocking member 6 that interlocks the lid members 4 in accordance with the operation of the pedal 5.

[0014] As shown in Figures 1, 4, and 5, the container body 2 comprises a storage section 11 having a bottom wall component 12 that is substantially rectangular in plan view, a pair of opposing long side wall components 13 that extend upward from a pair of opposing long sides of the bottom wall component 12, and a pair of opposing short side wall components 14 that extend upward from a pair of opposing short sides of the bottom wall component 12, an overhang 15 that protrudes from the entire circumference of the upper edge of the storage section 11 toward the outer circumference of the container body 2, and an edge wall component 16 that protrudes upward from the tip edge of the overhang 15. The storage section 11 is configured in a tapered shape that widens toward upward. The container body 2 in this embodiment is integrally constructed of polypropylene.

[0015] Furthermore, as shown in Figure 5, the overhang portion 15 of this embodiment includes a lower wall portion 17 extending from the upper edge of the storage portion 11 towards the outer circumference of the container body 2, a vertical wall portion 18 extending upward from the leading edge of the lower wall portion 17, and an upper wall portion 19 extending from the upper edge of the vertical wall portion 18 towards the outer circumference of the container body 2. In addition, the container body 2 of this embodiment is provided with a folded wall portion 20 that is connected to the upper edge of the portion corresponding to one of the short-side side wall portions 14 of the edge wall portion 16 (hereinafter also referred to as the "front side side wall portion 14a"), and extends downward and inclined outward toward the container body 2. The folded wall portion 20 extends until its lower edge is at the same height as the lower surface of the overhang portion 15. In addition, folded wall portions 20 are also provided in the other short-side side wall portion 14 (hereinafter also referred to as the "rear side side wall portion 14b") and in the portions corresponding to the pair of long-side side wall portions 13. These folded wall portions 20 extend downward from the upper wall portion 19 (until their lower edges are at the same height as the lower surface of the overhang portion 15) in such a manner that they extend the lower edge of the edge wall portion 16 downward.

[0016] As shown in Figures 6 and 7, each lid member 4 comprises 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 projecting downward from the outer peripheral edge of the top wall portion 21, and a substantially cylindrical shaft portion 23 projecting outward from near one side end of the outer surface of the portion of the frame wall portion 22 corresponding to the short side of the top wall portion 21. In this embodiment, the lid member 4 is integrally constructed from polypropylene.

[0017] Furthermore, as shown in Figure 3 and other figures, the lid member 4 of this embodiment is rotatably mounted to correspond to each long-side side wall portion 13 of the container body 2. Specifically, the rotation axis 24 of the lid member 4 (see Figure 6, etc.) is configured to extend along the upper edge of the long-side side wall portion 13, parallel to the lateral width direction of the long-side side wall portion 13, at a position above the upper wall portion 19 of the protruding portion 15 that corresponds to each long-side side wall portion 13. In other words, as shown in Figure 5, an axial hole 25 is provided above both ends of the upper wall portion 19 of the protruding portion 15 that corresponds to each long-side side wall portion 13, for the portion of the edge wall portion 16 that has a surface corresponding to each short-side side wall portion 14 (a surface facing the same side as the outer surface of each short-side side wall portion 14), thereby rotatably supporting the shaft portion 23 of the lid member 4.

[0018] Furthermore, the lid member 4 extends substantially parallel to the upper edge of the short-side side wall portion 14 and is configured to be rotatably displaceable between a closed position (see Figure 1, etc.) that closes the opening 3 of the container body 2 and an open position (see Figure 3, etc.) that extends substantially perpendicularly upward to the upper edge 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 edge of the frame wall portion 22 of the lid member 4 abuts against and is supported by the upper wall portion 19 corresponding to the short-side side wall portion 14 of the container body 2 (see Figures 13, 15, etc.). As shown in Figure 19, etc., 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, so that the upper wall portion 19 corresponding to the long-side side wall portion 13 does not hinder the rotation of the lid member 4. On the other hand, as shown in Figure 22 and other figures, when the lid member 4 is in the open position, the top wall portion 21 of the lid member 4 is supported by contacting the inner surface of the edge wall portion 16, which corresponds to the long side wall portion 13.

[0019] As shown in Figure 9, the interlocking member 6 comprises a lifting base portion 31 as a base portion having a pair of left and right vertical bars 32 extending vertically and an interlocking connecting portion 33 connecting the lower ends of the pair of vertical bars 32, an extension portion 34 extending in a direction perpendicular to the vertical bars 32 and connected to the upper ends of the pair of vertical bars 32, and arm portions 35 provided at both ends of the extension portion 34. The extension portion 34 is provided so as to protrude laterally from the pair of left and right vertical bars 32. As shown in Figure 4, the extension portion 34 in this embodiment is slightly longer than the distance between the upper edges of the pair of long-side wall portions 13 and slightly shorter than the distance between the vertical wall portions 18 of the overhang portion 15 corresponding to the pair of long-side wall portions 13.

[0020] Furthermore, each arm portion 35 protrudes from the end of the extension portion 34 in a direction that intersects with the extension direction of the extension portion 34 and also intersects with the extension direction of the lifting base portion 31. As will be described in detail later, each arm portion 35 contacts the corresponding lid member 4 in accordance with the displacement of the interlocking member 6, and is a part that applies force to the lid member 4 toward the open position and the closed position. The interlocking member 6 in this embodiment is integrally constructed by appropriately bending a metal rod-shaped body with a substantially circular cross-section.

[0021] In contrast, as shown in Figures 2, 4, and 5, the rear side wall portion 14b is provided with an interlocking housing portion 37, which is formed by recessing the center of the rear side wall portion 14b in the width direction inward of the container body 2, in order to position the lifting base portion 31 of the interlocking member 6 on the outer surface side of the container body 2 and to prevent the lifting base portion 31 from protruding outward from the outer surface of the container body 2. Furthermore, the lower wall portion 17 of the overhang portion 15 corresponding to the rear side wall portion 14b (above the interlocking housing portion 37) is provided with an insertion hole 38 that penetrates vertically, through which the lifting base portion 31 is inserted, and for positioning the lifting base portion 31 in the horizontal direction. The width of the insertion hole 38 in the width direction of the rear side wall portion 14b is slightly wider than the width of the lifting base portion 31, and the width of the insertion hole 38 in the thickness direction of the rear side wall portion 14b is slightly wider than the diameter of the vertical bar 32.

[0022] Then, the interlocking member 6 is attached to the container body 2 by inserting the lifting base portion 31 of the interlocking member 6 into the insertion hole 38 from above the container body 2. In this embodiment, the interlocking member 6 is attached to the container body 2 in a direction in which the arm portion 35 protrudes outward from the extending portion 34. Furthermore, when the interlocking member 6 is attached, the lifting base portion 31 is housed in the interlocking housing portion 37, and the extending portion 34 is housed inside the container body 2.

[0023] As shown in Figure 11, the pedal 5 comprises a roughly rectangular parallelepiped operating section 41 and a roughly rectangular parallelepiped pedal body 42 connected to the center of one of the long sides of the operating section 41, forming a roughly T-shape in plan view. Furthermore, the operating section 41 and the pedal body 42 are open downwards, and reinforcing ribs 43 are provided on the inside. In addition, a pedal connecting section 44 with a roughly C-shaped cross-section that opens upwards is provided at the end of the pedal body 42 that is not connected to the operating section 41. Furthermore, a roughly cylindrical pedal shaft section 45 is provided at an intermediate position in the longitudinal width direction of the pedal body 42, projecting laterally from the side surface of each long side of the pedal body 42. The pedal 5 in this embodiment is integrally constructed from polypropylene.

[0024] In contrast, as shown in Figure 2, a pedal housing section 46 for housing the pedal 5 is provided on the lower surface side of the bottom wall component 12 of the container body 2. The pedal housing section 46 extends along the longitudinal width direction of the container body 2 in the center of the short width direction of the container body 2 and includes a communication section 47 for housing the pedal body 42 of the pedal 5, an operation housing section 48 for housing the operation section 41 of the pedal 5, and a connection housing section 49 for housing the pedal connection section 44.

[0025] As shown in Figure 1, the operating part 41 of the pedal 5 is located on the front side wall portion 14a, and the operating housing portion 48 is also provided on the front side wall portion 14a. Furthermore, the portion of the front side wall portion 14a corresponding to the area above the operating housing portion 48 is recessed inward into the container body 2, and in particular, the lower part is recessed relatively large so that the toes can be pressed down on the upper surface of the operating part 41. In addition, as shown in Figure 2, pedal shaft holes 50 are provided in the left and right side walls of the communication portion 47 to rotatably support the pedal shaft portion 45. The pedal shaft portion 45 of the pedal 5 is fitted into the pedal shaft hole 50, so that the pedal 5 is rotatably attached to the container body 2 on the lower surface of the bottom wall component portion 12. In this embodiment, the pedal 5 is configured so that when attached to the container body 2, its entirety fits into the pedal housing portion 46, and the pedal 5 does not protrude outward from the outer circumferential surface of the container body 2.

[0026] Furthermore, as shown in Figure 2, the connecting housing portion 49 also serves as the lower part of the interlocking housing portion 37, and is the portion that positions the pedal connecting portion 44 below the interlocking member 6 housed in the interlocking housing portion 37. The interlocking connecting portion 33, which has a circular cross-section and corresponds to the lower end of the interlocking member 6, is fitted inside the pedal connecting portion 44, which has a roughly C-shaped cross-section, thereby rotatably connecting the interlocking member 6 (interlocking connecting portion 33) and the pedal 5 (pedal connecting portion 44). As a result, the interlocking member 6 is displaced up and down in response to the operation of the pedal 5.

[0027] In other words, as shown in Figures 1 and 2, when the pedal 5 is not being operated on the operating section 41 (not being pressed), the weight of the interlocking member 6 causes it to maintain a posture in which the pedal connecting section 44 side (rear end) is lowered and the operating section 41 side (front end) is raised, within a range in which it can rotate around the pedal shaft 45. Furthermore, when the pedal 5 is not being operated on the operating section 41, the extended portion 34 and the arm portion 35 of the interlocking member 6 are housed inside the container body 2 (see Figure 16).

[0028] On the other hand, as shown in Figure 3, when the operating section 41 is operated, the pedal 5 is positioned with the operating section 41 side (front end) lowered and the pedal connecting section 44 side (rear end) raised, causing the interlocking member 6 to be displaced upward. Furthermore, as will be described in more detail later, when the operating section 41 of the pedal 5 is operated, the extended portion 34 and the arm portion 35 of the interlocking member 6 protrude upward above the container body 2 (see Figure 22).

[0029] Furthermore, by connecting the interlocking member 6 to the pedal 5, the lifting base portion 31 of the interlocking member 6 is provided along the rear side wall portion 14b of the container body 2, and is in contact with or close to the outer surface of the rear side wall portion 14b. In addition, as described above, because the interlocking member 6 is provided on the outer side of the container body 2, interference between the interlocking member 6 and the contents of the container body 2 is prevented, which could hinder the lifting operation of the interlocking member 6 or adversely affect the contents. Moreover, the connection between the interlocking member 6 and the pedal 5 can be made relatively easily on the outside of the container body 2.

[0030] In addition, as shown in Figures 3 and 4, the trash can 1 of this embodiment is equipped with a pair of bag-holding members 53 for holding the top of a bag (garbage bag) that is attached to the inside of the container body 2. As shown in Figure 12, the bag-holding member 53 is equipped with a roughly U-shaped bag-holding body 54 and bag-holding shafts 55 that protrude outward from both ends of the bag-holding body 54. The bag-holding shafts 55 are cylindrical and have an enlarged diameter at the tip.

[0031] In contrast, as shown in Figure 5, the container body 2 is provided with a pair of bag-holding shaft holes 56 near the center in the lateral direction of the long-side wall portion 13, on the vertical wall portion 18 of the protruding portion 15 corresponding to each long-side wall portion 13. The bag-holding member 53 is rotatably attached to the container body 2 by fitting the bag-holding shaft portion 55 into the bag-holding shaft hole 56, with the bag-holding body 54 positioned so as to be placed along the inside of the upper edge of the container body 2.

[0032] The bag-fastening body 54 basically has a portion that is supported by the lower wall portion 17 of the protruding portion 15 and a portion that fits inside the storage portion 11, and has a roughly L-shaped cross-section (see Figures 12 and 22). In addition, both ends of the bag-fastening body 54 protrude upward in order to position the bag-fastening shaft portion 55 above the lower wall portion 17 (see Figures 3 and 12). Furthermore, as shown in Figure 4, the pair of bag-fastening members 53 use the same shape. In addition, of the pair of bag-fastening members 53, the bag-fastening member 53 provided on the back side wall portion 14b side is not supported by the lower wall portion 17 on both sides in the width direction of the back side wall portion 14b due to the fact that the back side wall portion 14b is uneven in the inner and outer directions of the container body 2, but near the center of the back side wall portion 14b in the width direction, it is supported by the portion of the lower wall portion 17 adjacent to the insertion hole 38.

[0033] Now, as shown in Figures 4, 9, 10, 21, etc., each arm portion 35 of the interlocking member 6 in this embodiment includes a first arm 61 that extends from the end of the extending portion 34, substantially perpendicular to the extending portion 34 and projecting substantially horizontally, and a second arm 62 that is provided so as to project upward from the tip of the first arm 61. In the state in which the interlocking member 6 is attached to the container body 2, the first arm 61 in this embodiment projects outward from the extending portion 34 that extends along the width direction of the rear side wall portion 14b (on the opposite side from the central part in the width direction of each long side side wall portion 13), and extends in a direction along the rotation axis 24 of the lid member 4 (see Figures 4, 6, and 17) (parallel to the rotation axis 24 of the lid member 4). Furthermore, the second arm 62 is substantially L-shaped and includes a first hanging portion 63 extending upward from the tip of the first arm 61, and a second hanging portion 64 extending from the tip of the first hanging portion 63, perpendicular to the first hanging portion 63, and toward the center of each short-side side wall portion 14 in the lateral direction.

[0034] In contrast, as shown in Figures 3, 4, and 7, the lid member 4 has a back-side projection 65 that protrudes from the lower surface when it is in the closed position, on the side of the back side wall 14b of the container body 2, and from a portion closer to the rotation axis 24 than the center in the short-width direction of the lid member 4. As shown in Figures 8, 16, 18, and 21, the back-side projection 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 direction of the short-side wall 14 when the lid member 4 is in the closed position. With the provision of this locking hole 66, the back-side projection 65 is composed of a pair of outer pieces 67 and an inner piece 68 arranged along the lateral direction (rotation axis 24 direction) of the lid member 4, and a tip-side piece 69 that connects the tip of the outer piece 67 and the tip of the inner piece 68 (see Figures 8 and 18). Furthermore, the outer piece 67 of this embodiment is connected to the inner surface of the frame wall portion 22, which corresponds to the short side portion of the lid member 4.

[0035] Furthermore, as shown in Figures 8 and 18, the lid member 4 is equipped with an auxiliary piece 70 that connects the inner piece 68 to the portion of the frame wall 22 on the rotation axis 24 side of the lid member 4. The auxiliary piece 70 extends parallel to the short side of the lid member 4 (see Figure 17). In addition, the projection length of the rear side projection piece 65 from the top wall 21 is longer than the projection length of the frame wall 22 from the top wall 21, and the projection length of the auxiliary piece 70 from the top wall 21 is approximately the same as the projection length of the frame wall 22 from the top wall 21, and shorter than the projection length of the rear side projection piece 65 from the top wall 21. In this embodiment, the distance between the auxiliary piece 70 and the tip side piece 69 of the rear side projection piece 65 is slightly longer than the width of the second arm 62 in the lateral direction of the rear side wall 14b.

[0036] In addition, as shown in Figure 18 and other figures, the container body 2 is provided with projection receiving recesses 71 that accommodate the back side projection 65 when the lid member 4 is in the closed position, such that the vertical wall portion 18 and the upper wall portion 19 are omitted at both ends of the protruding portion 15 corresponding to the back side side wall portion 14b (the edge wall portion 16 extends directly from the lower wall portion 17).

[0037] Here, the interlocking mechanism between the interlocking member 6 and the lid member 4 will be described. As shown in Figures 13, 14, 16, and 17, when the lid member 4 is in the closed position, the back-side projection 65 and the second arm 62 are positioned relative to each other at positions offset horizontally (in this example, in the width direction of the back-side wall 14b). In this embodiment, the back-side projection 65 is positioned adjacent to the center of the back-side wall 14b of the second arm 62 in the width direction. Also, as shown in Figure 15, the upper surface of the first arm 61 is in contact with or close to the lower edge of the auxiliary piece 70.

[0038] Next, when the lid member 4 is in the closed position, the pedal 5 is operated (the operating part 41 is pressed), causing the interlocking member 6 to be displaced upward. As shown in Figures 18 and 19, the auxiliary piece 70 of the lid member 4 comes into contact with the first arm 61 of the interlocking member 6, and an external force is applied from the first arm 61 toward the open position. This causes the lid member 4 to rotate upward. Furthermore, in this embodiment, as the interlocking member 6 is displaced upward and the lid member 4 is moved to the open position, the auxiliary piece 70 is pressed upward and toward the outside of the container body 2 by the first arm 61. Then, the inner piece 68 of the back-side projection 65 comes into contact with the upper surface of the first arm 61 and is pressed upward, causing the lid member 4 to be moved to the open position, which extends approximately vertically upward from the rotation axis 24. Of course, when the pedal 5 is operated, the pair of lid members 4 are displaced synchronously to the open position.

[0039] Furthermore, as shown in Figure 20 and other figures, in this embodiment, when the lid member 4 is opened by operating the pedal 5, the second hanging portion 64 of the second arm 62 and the upper part of the first hanging portion 63 are inserted into the locking hole 66 of the back side projection portion 65. Then, as shown in Figures 21 to 24, when the lid member 4 is fully open, the first hanging portion 63 penetrates the locking hole 66, and the second hanging portion 64 is positioned opposite (in this example, in contact with or close to) the upper surface of the tip side piece portion 69.

[0040] As shown in Figures 17, 24, etc., the auxiliary piece 70 and the back-side projection piece 65 (inner piece 68) extend in a direction perpendicular to the rotation axis 24 of the lid member 4, while 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). Therefore, when the lid member 4 is opened, the first arm 61 is prevented from coming off the auxiliary piece 70 and the back-side projection piece 65 (inner piece 68) during sliding motion, and stable sliding motion is ensured. In addition, as shown in Figures 8, 19, 21, etc., the portion of the auxiliary piece 70 that can come into contact with the first arm 61 has a shorter projection length from the top wall 21 than the other portions, and both ends are configured in an arc shape. This allows for the formation of a locking hole 66 in the back-side projection 65 that allows the second arm 62 to be inserted, while suppressing the protruding length of the back-side projection 65. Furthermore, when opening the lid member 4, the sliding from the auxiliary piece 70 of the first arm 61 to the back-side projection 65 (inner piece 68) becomes relatively smooth.

[0041] Next, as shown in Figures 21 to 23, when the pedal 5 is operated and the lid member 4 is in the open position, and the operation on the pedal 5 is released (the foot is removed from the pedal 5), the interlocking member 6 is displaced downward, and the lower surface of the second hook portion 64 of the second arm 62 of the arm portion 35 of the interlocking member 6 comes into contact with the upper-facing surface of the tip portion 69 of the rear side projection portion 65. As a result, an external force is applied to the lid member 4 (tip portion 69) from the interlocking member 6 (second hook portion 64) toward the closed position, and based on this external force, it is tilted and displaced toward the closed position (see Figure 18, etc.). As the lid member 4, which 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 displaced synchronously toward the closed position.

[0042] In addition, as shown in Figures 18 and 20, when the pedal 5 is operated and the lid member 4 is displaced from the open position to 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), and when the lid member 4 is in the closed position, as described above (as shown in Figures 14, 16, and 17), the back side projection 65 and the second arm 62 are positioned relative to each other in a horizontally offset position.

[0043] In this embodiment, the opening contact portion is formed by the lower edge portion of the auxiliary piece 70 when the lid member 4 is in the closed position and the inner piece 68 of the back side projection piece 65 (particularly the lower edge portion when the lid member 4 is in the open position). Furthermore, the opening action portion is formed by the first arm 61 (particularly the upper surface). In addition, the closing contact portion is formed by the tip side piece 69 of the back side projection piece 65 (particularly the upper surface when the lid member 4 is in the open position). Furthermore, the closing action portion is formed by the second arm 62 (particularly the lower surface of the second hook portion 64).

[0044] Furthermore, in this embodiment, the lid member 4 and the interlocking member 6 are configured not to interfere with each other when the lid member 4 is displaced from the closed position to the open position without operating the pedal 5. In other words, when the pedal 5 is not operated, the second arm 62 (second hook portion 64) of the arm portion 35 of the interlocking member 6, which is located below, is positioned outside the trajectory of the projection portion 65 on the back side of the lid member 4, which is displaced between the open position and the closed position. Therefore, the lid member 4 can be displaced to the open position without engaging the interlocking member 6, for example, by directly placing your hand on the lid member 4.

[0045] Furthermore, as shown in Figure 25, the trash can 1 of this embodiment is configured to be stacked vertically (nested) by setting the lid member 4 to the open position without operating the pedal 5 as described above (without displacing the interlocking member 6 upward), so that the lower part of the upper trash can 1 (container body 2) is housed inside the lower trash can 1 (container body 2). In addition, as shown in Figure 26, the trash can 1 can be configured without the bag-holding member 53 attached (in Figure 26, only the interlocking member 6 and pedal 5 are attached to the container body 2), and nesting is performed to enable more efficient storage.

[0046] Furthermore, as shown in Figure 27, the trash cans 1 of this embodiment are configured to be connectable to each other when placed side by side. That is, as shown in Figure 2, a side-by-side connecting portion 73 is provided on the outer surface of one of the long side walls 13 of the container body 2. Furthermore, as shown in Figure 1, a side-by-side connecting portion 74 is provided on the outer surface of the other long side wall 13, which is connected to the side-by-side connecting portion 73. The side-by-side connecting portion 73 and the side-by-side connecting portion 74 are configured to be detachable by relative vertical displacement, and when connected, relative horizontal displacement between the connected trash cans 1 is prevented.

[0047] As described in detail above, according to this embodiment, when the lid member 4 is in the closed position, the back-side projection 65 and the second arm 62 are positioned relative to each other at horizontally offset positions. Therefore, when the lid member 4 is in the closed position, the interlocking member 6, including the second arm 62 (second hanging portion 64, etc.), is not positioned opposite the upper surface of the back-side projection 65 (tip side projection 69, etc.). This configuration makes it possible to avoid situations such as the lid member 4 getting caught on the interlocking member 6 when removing the lid member 4 from the container body 2 in the closed position. Furthermore, it is possible to avoid situations where the attachment of the lid member 4 is hindered by the interlocking member 6 when attaching the lid member 4 to the container body 2 to which the interlocking member 6 is attached.

[0048] On the other hand, when the lid member 4 is in the open position due to operation of the pedal 5, the second hook portion 64 of the second arm 62 is positioned opposite the upper surface of the tip portion 69 of the rear side projection portion 65. Therefore, even if the lid member 4 and the interlocking member 6 are not connected, when the operation of the pedal 5 is released (when the interlocking member 6 is displaced downward), the second hook portion 64 of the second arm 62 comes into contact with the tip portion 69 of the rear side projection portion 65, applying an external force toward the closed position to the lid member 4. Thus, an interlocking mechanism between the pedal 5, the interlocking member 6, and the lid member 4 can be established. Therefore, when assembling the trash can 1, the lid member 4 can be made to work in conjunction with the pedal 5 simply by attaching it to the container body 2 (fitting the shaft portion 23 of the lid member 4 into the shaft hole 25 of the container body 2). Compared to a configuration where, for example, the lid member 4 needs to be connected to the interlocking member 6 in addition to being attached to the container body 2, the ease of assembly of the trash can 1 can be improved. Furthermore, the ease of removal of the lid member 4 from the container body 2 can also be improved.

[0049] Furthermore, when the lid member 4 is in the open position due to operation of the pedal 5, even if the lid member 4 is pulled upward or otherwise displaced in a direction that would cause it to detach from the container body 2, the second hook portion 64 of the second arm 62 contacts the tip portion 69 of the back surface projection portion 65, thereby restricting such displacement. Therefore, for example, if the pedal 5 is operated forcefully, the lid member 4 will be forcefully opened, and the recoil will cause the lid member 4 to detach from the container body 2, thus preventing accidental detachment of the lid member 4.

[0050] Furthermore, in this embodiment, when the lid member 4 is moved from the closed position to the open position without operating the pedal 5, the lid member 4 and the interlocking member 6 do not interfere with each other. Therefore, when the lid member 4 is moved from the closed position to the open position by directly touching it with one's hand without operating the pedal 5, situations such as the lid member 4 getting caught on the interlocking member 6 or the interlocking member 6 lifting up in conjunction with the lid member 4 are avoided, making it relatively easy to move the lid member 4 to the open position. Consequently, the operability when moving the lid member 4 to the open position by directly touching it with one's hand can be improved.

[0051] Furthermore, in this embodiment, the second arm 62 is composed of a first hook portion 63 that protrudes upward from the tip of the first arm 61, and a second hook portion 64 that protrudes from the tip of the first hook portion 63 toward the center of the longitudinal width direction of the extended portion 34. When the lid member 4 is opened by operating the pedal 5, the first hook portion 63 is inserted into the locking hole 66 of the back surface projection portion 65, and the lower surface of the second hook portion 64 and the upper surface of the tip side portion 69 are positioned opposite each other. In other words, when the lid member 4 is opened by operating the pedal 5, the second hook portion 64 of the second arm 62 and the first arm 61 are positioned vertically, and the tip side portion 69 and a part of the inner portion 68 of the back surface projection portion 65 are positioned between the second hook portion 64 and the first arm 61. This configuration makes it possible to make the structure of the interlocking member 6, specifically the parts that apply force to the lid member 4 toward the open and closed positions (first arm 61 and second hook 64), and the parts that receive force from the interlocking member 6 toward the open and closed positions (backside projection 65), as compact as possible.

[0052] Furthermore, the first arm 61 of the interlocking member 6 extends in a direction along the rotation axis 24 of the lid member 4 (approximately parallel to the rotation axis 24). As a result, the range over which the first arm 61 can contact the auxiliary piece 70 and the inner piece 68 of the rear side projection 65 can be increased (contact can be made along a line rather than just at a point), and when the pedal 5 is operated to open the lid member 4, the first arm 61 can be reliably brought into contact with the auxiliary piece 70 and the inner piece 68. Furthermore, for example, when the first arm 61 extends perpendicular to the rotation axis 24 of the lid member 4, even a slight misalignment between the first arm 61, the auxiliary piece 70, and the inner piece 68 when opening the lid member 4 can eliminate the sliding contact between them. Alternatively, when the first arm 61 is tilted relatively significantly with respect to the rotation axis 24, when opening the lid member 4, the lid member 4 may be pushed to one side or the other side in the direction along the rotation axis 24, making rotational displacement difficult. These situations can be avoided. Therefore, the operability when operating the pedal 5 to open the lid member 4 can be improved. In particular, when the contact area between the first arm 61 and the auxiliary piece 70 and the inner piece 68 increases, damage to the first arm 61, the auxiliary piece 70, and the inner piece 68 can be more reliably suppressed.

[0053] In addition, the lifting base portion 31 of the interlocking member 6 is provided along the rear side wall portion 14b of the container body 2 and is positioned to abut against or be close to the outer surface of the rear side wall portion 14b. Furthermore, the arm portion 35 protrudes outward from the tip of the extended portion 34 toward the outside of the container body 2. As a result, it is possible to minimize the reduction in the volume of the container body 2 due to the interlocking member 6. Moreover, for example, when stacking (nesting) trash cans 1 with the lid member 4 in the open position, or when nesting container bodies 2 with the interlocking member 6 attached but the lid member 4 not attached, the interlocking member 6 can be made to minimize the obstruction of nesting, thereby improving nesting efficiency and, consequently, the transportation and storage efficiency of the trash cans 1 (container body 2).

[0054] Furthermore, the lid members 4 are provided in pairs, and the lifting base portion 31 of the interlocking member 6 extends vertically at a position between the pair of lid members 4, while the extending portion 34 is provided to extend to a position near the rotation axis 24 of each of the pair of lid members 4. As a result, a pair of lid members 4 can be opened and closed simultaneously with a single interlocking member 6, and the structure of the interlocking member 6 can be simplified. In addition, since the lifting base portion 31 is provided at a position between the pair of lid members 4, when the lid members 4 are provided in pairs, the structure of the interlocking member 6 can be simplified, and the interlocking members 6 can be arranged in a balanced manner. Furthermore, since the extending portion 34 extends to a position near the rotation axis 24 of the lid members 4, the arm portions 35 (first arm 61 and second arm 62) provided at the tip of the extending portion 34 also come into contact with the back side projection portion 65 and auxiliary portion 70 at a position near the rotation axis 24 of the lid members 4. Therefore, the stroke amount of the interlocking member 6 when opening and closing the lid member 4 can be minimized, improving the operability of the pedal 5 (reducing the stroke amount of the pedal 5 when the lid member 4 is in the open position, improving the response speed in which the lid member 4 is opened and closed in response to the operation of the pedal 5, etc.).

[0055] In addition, the rear side projection 65 is provided with a locking hole 66 through which the second arm 62 is inserted when the pedal 5 is operated and the lid member 4 is in the open position. Therefore, interference between the second arm 62 (second hook portion 64) and the rear side projection 65 (tip portion 69) when the lid member 4 is in the open position by operating the pedal 5 can be efficiently avoided. When the lid member 4 is in the open position by operating the pedal 5, the time from when the pedal 5 is released until the second hook portion 64 comes into contact with the tip portion 69 and the lid member 4 is displaced to the closed position can be shortened (improvement of the response speed of the lid member 4). Consequently, the operability of opening and closing the lid member 4 by the pedal 5 can be improved.

[0056] Furthermore, the embodiment is not limited to the description above, and may be implemented as follows, for example. Of course, other applications and modifications not exemplified below are also possible.

[0057] (a) In the above embodiment, the arm portion 35 (first arm 61) protrudes outward from the end of the extension portion 34 perpendicular to the extension portion 34 and outward from the container body 2, but it may also protrude inward from the end of the extension portion 34 perpendicular to the extension portion 34 and outward from the container body 2. However, as in the above embodiment, by making the arm portion 35 (first arm 61) protrude outward from the end of the extension portion 34 perpendicular to the extension portion 34 and outward from the container body 2, the arm portion 35, the back side projection portion 65, and the auxiliary piece portion 70 can be positioned outside the storage portion 11. This makes it possible to avoid the arm portion 35, the back side projection portion 65, and the auxiliary piece portion 70 interfering with the contents when the lid member 4 is in the closed position, and also makes it possible to avoid the back side projection portion 65 of the lower trash can 1 interfering with the upper trash can 1 when the trash cans 1 are nested together with the lid member 4 in the open position without operating the pedal 5.

[0058] Furthermore, in the above embodiment, the first arm 61 extends parallel to the rotation axis 24 of the lid member 4, but the configuration is not limited to this, and it is sufficient that when the interlocking member 6 rises in response to the operation of the pedal 5, it comes into contact with the auxiliary piece 70 and the inner piece 68 of the lid member 4, thereby applying an external force toward the open position to the lid member 4. Moreover, the cross-sectional shape of the first arm 61 is not particularly limited and can be changed as appropriate. However, if the portion of the first arm 61 that can come into contact with the auxiliary piece 70 and the inner piece 68 is made of a curved surface, and the first arm 61 is configured to extend parallel to the rotation axis 24 of the lid member 4, the lid member 4 can be rotated and displaced more smoothly.

[0059] In addition, the shape of the second arm 62 is not particularly limited, and it is sufficient that it is configured such that when the operation of the pedal 5 is released and the interlocking member 6 descends, it comes into contact with the tip side piece 69 of the lid member 4 and applies an external force toward the closed position to the lid member 4 (in the state where the lid member 4 is in the open position due to the operation of the pedal 5, the second arm is positioned opposite the upper surface of the back side projection piece 65). For example, the second arm 62 may be configured to extend upward from the tip of the first arm 61, tilting toward the central part of the extending portion 34.

[0060] Furthermore, the shape of the part of the lid member 4 that comes into contact with the arm portion 35 and to which an external force is applied toward the open or closed position 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 come into contact with the lower surface of the top wall portion 21 of the lid member 4, causing the lid member 4 to be displaced toward the open position.

[0061] (b) In the above embodiment, when the lid member 4 is in the open position due to the operation of the pedal 5, the second hook portion 64 of the interlocking member 6 and the first arm 61 are arranged vertically, and the back side projection portion 65 (tip side portion 69 and inner portion 68) is arranged between the second hook portion 64 and the first arm 61. However, the configuration is not limited to this, and it is sufficient that the lid member 4 opens and closes in conjunction with the operation of the pedal 5, and that the interlocking member 6 does not get caught on the lid member 4 when the lid member 4 is lifted from the closed position (for example, displaced to the open position) without operating the pedal 5.

[0062] For example, the lid member 82 of the trash can 81 shown in Figures 28 and 29 (instead of the back-side projection 65 and auxiliary piece 70 of the above embodiment) includes a first projection 83 and a second projection 84 that project downward from the lower surface of the lid member 82 in the closed position and are spaced apart vertically from each other when the lid member 82 is in the open position, and an auxiliary piece 85 that connects the side edges of the first projection 83 and the second projection 84 on the side of the lid member 4 in the lateral direction center. Furthermore, the arm portion 87 of the interlocking member 86 is composed of a first arm 89 that projects outward from both ends of the extending portion 88 perpendicular to 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. Furthermore, when the lid member 82 is in the open position due to pedal operation, the lower end of the second arm 90 is positioned opposite the upper surface of the second projection 84 (the first arm 89 and the second arm 90 are positioned between the first projection 83 and the second projection 84).

[0063] When the lid member 82 is in the closed position, the upper surface of the first arm 89 and the lower edge of the auxiliary piece 85 are positioned opposite each other (in this example, they are in contact or close to each other). Then, as shown in Figure 29, when the pedal is operated and the interlocking member 86 is displaced upward, the auxiliary piece 85 is pressed upward by the first arm 89, and the lid member 82 is displaced to the open position. Subsequently, the first arm 89, which was sliding against the auxiliary piece 85, slides against the lower surface of the first projection 83, and the first projection 83 is pressed upward by the first arm 89, after which the lid member 82 is set to the open position. The second projection 84 is provided with a hole 91 to avoid interference with the second arm 90 when the lid member 82 rotates.

[0064] As shown in Figure 28, when the lid member 82 is in the open position due to pedal operation, the second arm 90 is positioned opposite the upper surface of the second projection 84, as described above. Furthermore, when the pedal operation is released from the state where the lid member 82 is in the open position due to pedal operation, the lower end of the second arm 90 comes into contact with the upper surface of the second projection 84 as the interlocking member 86 is displaced downward, thereby applying an external force to the lid member 82 toward the closed position. As the lid member 82 tilts to the closed position to a certain extent from the open position, the lid member 82 is displaced toward the closed position by its own weight.

[0065] Furthermore, when the lid member 82 is in the closed position, the second projection 84 (and the first projection 83) and the arm portion 87 are positioned relative to each other at horizontally offset positions. In other words, when the lid member 82 is in the closed position, the interlocking member 86, including the arm portion 87, is not positioned opposite the upper surface of the second projection 84. In this embodiment, the first arm 89 corresponds to the opening action portion, the second arm 90 corresponds to the closing action portion, the auxiliary piece 85 and the first projection 83 correspond to the opening contact portion, and the second projection 84 corresponds to the closing contact portion.

[0066] Even when adopting the above configuration, similar to the above embodiment, when the pedal is operated, the lid member 82 can be linked to the pedal operation, and when the lid member 82 is lifted without operating the pedal (for example, when it is displaced to the open position), the linkage member 86 can be configured not to get caught on the lid member 82. As a result, the assembly workability of the trash can 81 can be improved.

[0067] Furthermore, the shapes of the arm portion 87, the first projection portion 83, and the second projection portion 84 are not particularly limited. As shown in Figures 30 and 31, the second arm 90 may be omitted from the arm portion 87, and when the pedal operation is released and the lid member 82 is placed in the closed position, the lower surface of the first arm 89 may contact the upper surface of the second projection portion 84, thereby applying an external force to the lid member 82 toward the closed position. In addition, if this configuration is adopted, the hole 91 of the second projection portion 84 can be omitted. Incidentally, by providing the second arm 90, when 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 projection portion 84 can be minimized, thereby shortening the time from when the pedal operation is released until the lid member 82 begins to close. Furthermore, instead of the first arm 89 protruding outward from the container body 92 perpendicular to the extension portion 88, it is also possible to protrude inward from the container body 92 perpendicular to the extension portion 88.

[0068] Furthermore, the lid member 82 of the trash can 81 shown in Figures 28 and 29 (Figures 30 and 31) has a frame wall portion 94 that protrudes downward from the outer peripheral edge of the top wall portion 93 of the lid member 82. On the side portion extending perpendicular to the rotation axis of the lid member 82 (particularly the open end portion of the lid member 82), a handle portion 95 is provided that is concave in shape so that a fingertip can be inserted between the side edge of the lid member 82 in the closed position and the container body 92, and also so that a fingertip can be placed on the side edge of the lid member 82. The provision of the handle portion 95 makes it easier to directly open and close the lid member 82, such as by directly placing a hand on the lid member 82 in the closed position and displacing it towards the open position. The shape of the handle portion 95 is not particularly limited, and for example, it may be configured to have a roughly hook-shaped cross-section that provides a better grip for the fingertip.

[0069] (c) In the above embodiment, a pair of lid members 4 are provided, but the opening 3 of the container body 2 may be opened and closed by a single lid member. However, by opening and closing the opening 3 of the container body 2 with a pair of lid members 4, it is possible to reduce the burden on the mechanism that interlocks the lid members 4 and the interlocking member 6, shorten the time required to open and close the trash can 1, etc. Also, in the above embodiment, the lid members 4 are attached in accordance with the long side wall portion 13 (so that the rotation shaft 24 extends along the width direction of the long side wall portion 13), but they may also be attached in accordance with the short side wall portion 14.

[0070] Furthermore, in the above embodiment, the interlocking member 6 is mounted on the short side wall portion 14 (back side wall portion 14b) rather than the long side side wall portion 13 to which the lid member 4 is mounted; however, it may be mounted on the same side wall portion to which the lid member 4 is mounted (especially when only one lid member 4 is mounted on the container body 2). In this case, the arm portion may be such that, for example, the first arm as the opening action portion is provided so as to extend the extension portion 34 (composed of both ends of the extension portion 34), and the second arm may include a first hook portion extending upward from the tip of the first arm and a second hook portion as the closing action portion extending horizontally and substantially perpendicular to the first arm from the tip of the first hook portion. In addition, in the above embodiment, the container body 2 is in the shape of a square box, but the shape of the container body 2 is not particularly limited, and for example, it may be configured in a substantially cylindrical shape.

[0071] Furthermore, in the above embodiment, the pair of lid members 4 are configured to have different shapes (the formation positions of the back-side projection 65 and the auxiliary piece 70 are different), but they may also be of the same shape (for example, by providing a pair of back-side projection 65 and auxiliary piece 70 to create a symmetrical shape). In this case, the lid members 4 can be standardized, improving work efficiency and convenience in inventory management, etc.

[0072] In addition, in the above embodiment, the lid member 4 is provided with a protruding shaft portion 23 and the container body 2 is provided with a shaft hole 25. However, the container body 2 may be provided with a shaft portion and the lid member 4 may be provided with a shaft hole or a bottomed shaft hole. Furthermore, a configuration may be adopted in which the lid member 4 can be opened without operating the pedal 5, making it easier to remove the lid member 4 from the container body 2 (for example, the shaft hole provided in the lid member 4 has a roughly C-shape that opens downward when the lid member 4 is in the open position, making it easier to pull the open lid member 4 upward). Note that when the pedal 5 is operated to open the lid member 4, the second arm 62 of the interlocking member 6 catches on the back side protruding piece 65 (tip side piece 69) of the lid member 4, so that the lid member 4 cannot be removed from the container body 2.

[0073] (d) Furthermore, the shape and arrangement of the interlocking member 6 and the pedal 5 are not particularly limited. For example, the interlocking member 6 may be composed of multiple parts that are displaceable relative to each other. However, considering the workability and cost of manufacturing the trash can 1, it is desirable to keep the number of parts to a minimum. Furthermore, the pedal 5 and the interlocking member 6 may be configured to protrude outward from the outer surface of the container body 2. However, in order to save space when installing the trash can 1 and to 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 surface of the container body 2. Furthermore, as in the above embodiment, by making the part of the short-side wall portion 14 that corresponds to the part above the operation housing portion 48 (up to the upper edge of the short-side wall portion 14 or its vicinity) recessed inward from the container body 2, it is possible to easily confirm the position of the operation portion 41 of the pedal 5 from above, and the strength of the short-side wall portion 14 can be improved.

[0074] Furthermore, in the above embodiment, the operating member that the user operates when opening the trash can 1 is embodied as a pedal 5 intended for operation with the toes, but the configuration is not limited to this, and it can also be applied to a handle, button, etc. intended for operation with the hands.

[0075] Furthermore, in the above embodiment, a pair (2) of lid members 4 are configured to be opened and closed by one interlocking member 6 and one pedal 5, but an interlocking member and 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 sides, with an interlocking member that interlocks the left pedal with the left lid member, and an interlocking member that interlocks the right pedal with the right lid member, so that when one pedal is pressed, one lid member opens, and when both pedals are pressed, both lid members open. Also, for example, if there are three or more lid members, the system may be configured to include an interlocking member and pedal that opens and closes multiple lid members at once, and an interlocking member and pedal that opens and closes one lid member separate from the multiple lid members.

[0076] In addition, although the interlocking member 6 has a symmetrical shape in the above embodiment, it may also have an asymmetrical shape. For example, in accordance with the fact that the pedal 5 is provided at a position shifted to the right of the center of the container body 2 in the width direction, the lifting base portion 31 may also be provided at a position shifted to the right of the center of the interlocking member 6 in the width direction (the extension portion 34 extending to the left from the lifting base portion 31 and the extension portion 34 extending to the right may have different extension lengths). Furthermore, for example, in a configuration where one of a pair of lid members 4 has a different area in plan view (different weight), the position of the lifting base portion 31 in the width direction of the interlocking member 6 may be set according to the balance of the pair of lid members 4.

[0077] (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, or polyamide. Furthermore, the interlocking member 6 is made by bending a metal rod, but it can also be made of a resin material or the like.

[0078] Furthermore, although the above embodiment is embodied as a trash can 1 with a lid, it can also be used as a storage box for storing items other than trash (for example, balls, toys, miscellaneous goods, materials, etc.). In addition, although the above embodiment is configured to allow nesting of trash cans 1 with the lid member 4 in the open position, or container bodies 2 with the lid member 4 removed, or to connect trash cans 1 side by side using a locking structure, it can also be applied to trash cans 1 that do not allow these features.
