DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment will be described below with reference to the drawings. As shown in Figures 1 to 3, 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 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 operated by a user by stepping on it with the toes, and an interlocking member 6 that interlocks the lid member 4 in response to the operation of the pedal 5.

[0013] 1, 4, 5, etc., the container body 2 includes a bottom wall component 12 that is generally rectangular in plan view, a storage section 11 that includes a pair of opposing long side wall portions 13 extending upward from a pair of opposing long side edges of the bottom wall component 12, and a pair of opposing short side wall portions 14 extending upward from a pair of opposing short side edges of the bottom wall component 12, a protruding portion 15 that protrudes from the entire periphery of the upper edge of the storage section 11 toward the outer periphery of the container body 2, and an edge wall portion 16 that protrudes upward from the tip edge of the protruding portion 15. The storage section 11 is configured in a tapered shape that widens upward. Note that the container body 2 of this embodiment is integrally formed from polypropylene.

[0014] 5, the protruding portion 15 of this embodiment includes a lower wall portion 17 extending from the upper edge of the storage portion 11 toward the outer periphery of the container body 2, a vertical wall portion 18 extending upward from the tip edge of the lower wall portion 17, and an upper wall portion 19 extending from the upper edge of the vertical wall portion 18 toward the outer periphery of the container body 2. Furthermore, the container body 2 of this embodiment is provided with a folded wall portion 20 that is connected to the upper edge of a portion of the edge wall portion 16 that corresponds to one of the short side wall portions 14 (hereinafter also referred to as the "front side side wall portion 14a") and extends downward at an angle outward from the container body 2. The folded wall portion 20 extends until its lower edge is at the same height as the underside of the protruding portion 15. In addition, folded wall portions 20 are also provided on the other short side side wall portion 14 (hereinafter also referred to as the "rear side side wall portion 14b") and the portion corresponding to the pair of long side side wall portions 13, and these folded wall portions 20 extend downward from the upper wall portion 19 (until their lower edge portions are at the same height as the underside of the protrusion portion 15) in a manner that extends the lower edge portion of the edge wall portion 16 downward.

[0015] 6, 7, etc., each lid member 4 includes a generally 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 generally cylindrical shaft portion 23 protruding outward from a portion of the frame wall portion 22 near one side end of the outer surface of the portion corresponding to the short side edge of the top wall portion 21. The lid member 4 of this embodiment is integrally made of polypropylene.

[0016] 3 and other figures, the lid member 4 of this embodiment is rotatably attached to correspond to each long-side sidewall portion 13 of the container body 2. Specifically, at an upper position of the upper wall portion 19 of the overhanging portion 15 at a portion corresponding to each long-side sidewall portion 13, a rotation shaft 24 (see FIG. 6 and other figures) of the lid member 4 is configured to extend along the upper edge of the long-side sidewall portion 13 and parallel to the width direction of the long-side sidewall portion 13. That is, as shown in FIG. 5, for portions of the edge wall portion 16 having surfaces corresponding to each short-side sidewall portion 14 (surfaces facing the same side as the outer surfaces of the short-side sidewall portions 14), shaft holes 25 for rotatably supporting the shaft portions 23 of the lid member 4 are provided above both end portions of the upper wall portion 19 of the overhanging portion 15 at portions corresponding to each long-side sidewall portion 13.

[0017] The lid member 4 extends generally parallel to the upper edges of the short-side sidewalls 14 and is rotatable between a closed position (see FIG. 1, etc.) in which it closes the opening 3 of the container body 2 and an open position (see FIG. 3, etc.) in which it extends generally perpendicularly upward to the upper edges of the short-side sidewalls 14 and opens the opening 3 of the container body 2. When the lid member 4 is in the closed position, the lower edges of the frame wall 22 of the lid member 4 abut against and are supported by upper wall portions 19 corresponding to the short-side sidewalls 14 of the container body 2 (see FIGS. 13, 15, etc.). As shown in FIG. 19, etc., the upper wall portions 19 corresponding to the long-side sidewalls 13 are positioned slightly lower than the upper wall portions 19 corresponding to the short-side sidewalls 14, so that the upper wall portions 19 corresponding to the long-side sidewalls 13 do not interfere with the rotation of the lid member 4. On the other hand, as shown in Figure 22, when the cover member 4 is in the open position, the top wall portion 21 of the cover member 4 is supported by abutting against the inner surface of the edge wall portion 16 corresponding to the long side side wall portion 13.

[0018] As shown in FIG. 9 and other figures, the interlocking member 6 includes a lifting base 31 serving as a base including a pair of left and right vertical bars 32 extending up and down and an interlocking connector 33 connecting the lower ends of the pair of vertical bars 32, an extending portion 34 extending 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 extending portion 34. The extending portion 34 is provided so as to protrude laterally beyond the pair of left and right vertical bars 32. As shown in FIG. 4 and other figures, the extending portion 34 in this embodiment is slightly longer than the distance between the upper edges of the pair of long-side sidewall 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 sidewall portions 13.

[0019] 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 is a portion that comes into contact with the corresponding cover member 4 in response to the displacement of the interlocking member 6, and applies a force to the cover member 4 toward the open position and the closed position. Note that the interlocking member 6 in this embodiment is integrally formed by appropriately bending a metal rod-shaped body having a substantially circular cross section.

[0020] 2, 4, 5, etc., the rear side wall 14b is provided with an interlocking housing section 37 formed by recessing the central portion of the rear side wall 14b inward in the width direction of the container body 2 so that the lifting base section 31 of the interlocking member 6 is disposed on the outer surface of the container body 2 and the lifting base section 31 does not protrude outward beyond the outer circumferential surface of the container body 2. Furthermore, the lower wall 17 of the protruding section 15 corresponding to the rear side wall 14b (above the interlocking housing section 37) is provided with an insertion hole 38 that penetrates vertically, through which the lifting base section 31 is inserted and which positions the lifting base section 31 in the horizontal direction. The width of the insertion hole 38 in the width direction of the rear side wall 14b is slightly wider than the width of the lifting base section 31, and the width of the insertion hole 38 in the thickness direction of the rear side wall 14b is slightly wider than the diameter of the vertical rod 32.

[0021] The interlocking member 6 is attached to the container body 2 by inserting the lifting / lowering 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 with the arm portion 35 projecting outward from the extension portion 34 of the container body 2. In addition, when the interlocking member 6 is attached, the lifting / lowering base portion 31 is housed in the interlocking housing portion 37, and the extension portion 34 is housed inside the container body 2.

[0022] As shown in FIG. 11 and other figures, the pedal 5 includes a substantially rectangular parallelepiped operating portion 41 and a pedal body 42 also having a substantially rectangular parallelepiped shape connected to the center of one long side of the operating portion 41, forming a substantially T-shape in a plan view. The operating portion 41 and the pedal body 42 are open downward, and a reinforcing rib 43 is provided on the inside thereof. The end of the pedal body 42 that is not connected to the operating portion 41 is provided with a pedal connecting portion 44 that is open upward and has a substantially C-shaped cross section. A substantially cylindrical pedal shaft 45 is provided at a central position in the longitudinal width direction of the pedal body 42, protruding laterally from the side surface of each long side of the pedal body 42. The pedal 5 of this embodiment is integrally formed from polypropylene.

[0023] 2 and other figures, a pedal accommodating section 46 for accommodating the pedal 5 is provided on the underside of the bottom wall forming section 12 of the container body 2. The pedal accommodating section 46 extends along the longitudinal 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 that accommodates the pedal body 42 of the pedal 5, an operation accommodating section 48 that accommodates the operation section 41 of the pedal 5, and a connection accommodating section 49 that accommodates the pedal connection section 44.

[0024] As shown in FIG. 1 and other figures, the operating portion 41 of the pedal 5 is disposed on the front side wall 14a, and the operating storage portion 48 is also disposed on the front side wall 14a. The portion of the front side wall 14a above the operating storage portion 48 is recessed inwardly of the container body 2. The lower portion, in particular, is recessed relatively deeply so that the user can step on the upper surface of the operating portion 41. Additionally, as shown in FIG. 2, pedal shaft holes 50 are provided on the left and right side walls of the communication portion 47 to rotatably support the pedal shaft 45. The pedal shaft 45 of the pedal 5 is fitted into the pedal shaft holes 50, thereby rotatably attaching the pedal 5 to the container body 2 on the underside of the bottom wall forming portion 12. The pedal 5 of this embodiment is configured so that, when attached to the container body 2, its entirety is accommodated in the pedal storage portion 46, and the pedal 5 does not protrude outward beyond the outer circumferential surface of the container body 2.

[0025] 2, the linkage housing 49 also serves as the lower portion of the interlocking housing 37, and is a portion for positioning the pedal connecting portion 44 below the interlocking member 6 housed in the interlocking housing 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 into the pedal connecting portion 44, which has a substantially C-shaped cross section, thereby rotatably connecting the interlocking member 6 (interlocking connecting portion 33) and the pedal 5 (pedal connecting portion 44). This allows the interlocking member 6 to be displaced up and down in response to operation of the pedal 5.

[0026] 1 and 2, when the operation unit 41 of the pedal 5 is not being operated (depressed), the pedal 5 maintains a posture in which the pedal connecting unit 44 side (rear end side) is lowered and the operation unit 41 side (front end side) is raised within a range of rotational displacement around the pedal shaft 45 due to the weight of the interlocking member 6. Furthermore, when the operation unit 41 of the pedal 5 is not being operated, the extension part 34 and the arm part 35 of the interlocking member 6 are accommodated inside the container body 2 (see FIG. 16).

[0027] 3, when the operation unit 41 is operated, the operation unit 41 side (front end side) of the pedal 5 is lowered and the pedal connecting portion 44 side (rear end side) is raised, and the interlocking member 6 is displaced upward. In addition, as will be described in detail later, when the operation unit 41 of the pedal 5 is operated, the extension portion 34 and the arm portion 35 of the interlocking member 6 are configured to protrude upward beyond the container body 2 (see FIG. 22).

[0028] 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 back side wall portion 14b of the container body 2 and is in contact with or close to the outer surface of the back side wall portion 14b. Furthermore, by providing the interlocking member 6 on the outer surface of the container body 2 as described above, it is possible to avoid situations in which the interlocking member 6 interferes with the contents of the container body 2, hindering the lifting and lowering operation of the interlocking member 6 or adversely affecting the contents, and it is also possible to connect the interlocking member 6 to the pedal 5 relatively easily outside the container body 2.

[0029] 3, 4, etc., the trash can 1 of this embodiment is provided with a pair of bag stopper members 53 for holding the upper part of a bag (garbage bag) attached to the inside of the container body 2. As shown in Fig. 12, the bag stopper members 53 are provided with a substantially U-shaped bag stopper main body 54 and bag stopper shafts 55 that protrude outward from both ends of the bag stopper main body 54. The bag stopper shafts 55 are cylindrical and have an enlarged diameter portion on the tip end side.

[0030] 5, the container body 2 is provided with a pair of bag stopper shaft holes 56 at positions near the center of the width direction of the long side wall portions 13 on the vertical wall portions 18 of the protruding portions 15 corresponding to each long side side wall portion 13. The bag stopper main body 54 is oriented so as to be able to be disposed along the inside of the upper edge portion of the container body 2, and the bag stopper shaft portions 55 are fitted into the bag stopper shaft holes 56, whereby the bag stopper member 53 is rotatably attached to the container body 2.

[0031] The bag stopper body 54 basically has a portion 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 generally L-shaped cross section (see FIGS. 12 and 22). Both ends of the bag stopper body 54 protrude upward so that the bag stopper shaft 55 is positioned above the lower wall portion 17 (see FIGS. 3 and 12). As shown in FIG. 4, the pair of bag stopper members 53 have the same shape. Furthermore, the bag stopper member 53 provided on the rear side wall portion 14b side of the pair of bag stopper members 53 is not supported by the lower wall portion 17 on both sides of the rear side wall portion 14b in the width direction because the rear side wall portion 14b is uneven in the inner and outer periphery directions of the container body 2. However, the bag stopper member 53 is supported by a portion of the lower wall portion 17 adjacent to the insertion hole 38 near the center of the rear side wall portion 14b in the width direction.

[0032] 4, 9, 10, 21, etc., each arm portion 35 of the interlocking member 6 of this embodiment includes a first arm 61 that protrudes from an end of the extending portion 34 in a substantially horizontal direction, substantially perpendicular to the extending portion 34, and a second arm 62 that protrudes upward from the tip of the first arm 61. When the interlocking member 6 is attached to the container body 2, the first arm 61 of this embodiment protrudes outward from the container body 2 (the opposite side to the center in the horizontal direction of each long side side wall portion 13) from the extending portion 34 that extends along the horizontal direction of the back side side wall portion 14b, and extends in a direction along (parallel to) the rotation axis 24 of the lid member 4 (see FIGS. 4, 6, 17). Furthermore, the second arm 62 has 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 the width of each short side wall portion 14, and is approximately L-shaped.

[0033] 3, 4, 7, etc., the lid member 4 has a backside protrusion 65 that protrudes from the underside of the lid member 4 when in the closed position, toward the backside sidewall 14b of the container body 2 and toward the rotation axis 24 from the center of the lid member 4 in the short width direction. As shown in FIGS. 8, 16, 18, 21, etc., the backside protrusion 65 has a locking hole 66 that penetrates vertically when the lid member 4 is in the open position by operating the pedal 5, and penetrates the short side sidewall 14 in the lateral direction when the lid member 4 is in the closed position. By providing the locking hole 66, the backside protrusion 65 is configured by a pair of outer and inner pieces 67 and 68 that are aligned along the lateral width direction (the direction of the rotation axis 24) of the lid member 4, and a tip side piece 69 that connects the tip of the outer piece 67 to the tip of the inner piece 68 (see FIGS. 8 and 18). In this embodiment, the outer piece 67 is connected to the inner surface of the frame wall 22 corresponding to the short side of the cover member 4.

[0034] 8, 18, etc., the cover member 4 includes an auxiliary piece 70 that connects the inner piece 68 and a portion of the frame wall 22 on the rotation shaft 24 side of the cover member 4. The auxiliary piece 70 extends parallel to the short side of the cover member 4 (see FIG. 17). Furthermore, the protruding length of the rear surface-side protruding piece 65 from the top wall 21 is longer than the protruding length of the frame wall 22 from the top wall 21, and the protruding length of the auxiliary piece 70 from the top wall 21 is approximately the same as the protruding length of the frame wall 22 from the top wall 21 but shorter than the protruding length of the rear surface-side protruding piece 65 from the top wall 21. In this embodiment, the distance between the auxiliary piece 70 and the tip piece 69 of the rear surface-side protruding piece 65 is slightly longer than the width of the second arm 62 in the lateral direction of the rear surface-side sidewall 14b.

[0035] In addition, as shown in Figure 18, etc., the container body 2 has a protrusion accommodating recess 71 at both ends of the protrusion portion 15 corresponding to the back side side wall portion 14b, in such a manner that the vertical wall portion 18 and the upper wall portion 19 are omitted (the edge wall portion 16 extends directly from the lower wall portion 17), and which accommodates the back side protrusion portion 65 when the lid member 4 is in the closed position.

[0036] Here, the interlocking mode between the interlocking member 6 and the cover member 4 will be described. As shown in Figures 13, 14, 16, and 17, when the cover member 4 is in the closed position, the rear surface-side protrusion 65 and the second arm 62 are relatively positioned at positions offset in the horizontal direction (in the width direction of the rear surface-side sidewall 14b in this example). In this embodiment, the rear surface-side protrusion 65 is positioned adjacent to the center of the rear surface-side sidewall 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 positioned in contact with or close to the lower side of the auxiliary piece 70.

[0037] Next, when the pedal 5 is operated (the operating portion 41 is stepped on) to displace the interlocking member 6 upward from the closed position, as shown in FIGS. 18 and 19 , the auxiliary piece 70 of the lid member 4 abuts against 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 displaces upward and the lid member 4 is placed in the open position, the auxiliary piece 70 is pressed upward and outward from the container body 2 by the first arm 61, and then the inner piece 68 of the back-side protrusion 65 abuts against the upper surface of the first arm 61 and is pressed upward. This causes the lid member 4 to be placed in 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.

[0038] 20 and other figures, in this embodiment, when the pedal 5 is operated to place the cover member 4 in the open position, the second hook portion 64 of the second arm 62 and the upper part of the first hook portion 63 are inserted into the locking hole 66 of the rear surface protrusion portion 65. Then, as shown in Figures 21 to 24, when the cover member 4 is in the completely open position, the first hook portion 63 passes through the locking hole 66, and the second hook portion 64 is arranged to face the upper surface of the tip side piece 69 (in this example, it is in contact with or close to it).

[0039] 17, 24, etc., the auxiliary piece 70 and the back-side protrusion 65 (inner piece 68) extend in a direction perpendicular to the rotation axis 24 of the cover member 4, while the first arm 61 extends parallel to the rotation axis 24 of the cover member 4 (furthermore, the second arm 62 is configured to be able to be inserted into the locking hole 66). Therefore, when the cover member 4 is in the open position, the first arm 61 is prevented from coming off the auxiliary piece 70 and the back-side protrusion 65 (inner piece 68) during sliding with the auxiliary piece 70 and the back-side protrusion 65 (inner piece 68), ensuring stable sliding movement. In addition, as shown in FIGS. 8, 19, 21, etc., the portion of the auxiliary piece 70 that can come into contact with the first arm 61 is configured to protrude shorter from the top wall 21 than the other portions, and both ends thereof are configured in an arc shape. This makes it possible to form a locking hole 66 in the back side protrusion portion 65 through which the second arm 62 can be inserted while suppressing the protrusion length of the back side protrusion portion 65, and also makes the sliding from the auxiliary piece portion 70 of the first arm 61 to the back side protrusion portion 65 (inner piece portion 68) relatively smooth when the cover member 4 is opened.

[0040] Next, as shown in FIGS. 21 to 23 , when the pedal 5 is operated to place the cover member 4 in the open position, the pedal 5 is released (the foot is removed from the pedal 5), causing the interlocking member 6 to move downward. The lower surface of the second hook 64 of the second arm 62 of the arm portion 35 of the interlocking member 6 abuts against the upward-facing surface of the tip piece 69 of the back-side protrusion 65. As a result, an external force is applied from the interlocking member 6 (second hook 64) toward the closed position, causing the cover member 4 (tip piece 69) to tilt toward the closed position (see FIG. 18 , etc.). As the cover member 4, which was in the open position, tilts toward the closed position to some extent, the cover member 4 moves to the closed position under its own weight. Of course, when the pedal 5 is released, the pair of cover members 4 move synchronously toward the closed position.

[0041] In addition, as shown in Figures 18, 20, etc., when the pedal 5 is operated to displace the cover member 4 from the open position to the closed position, the second arm 62 is released from the engagement hole 66 (the second arm 62 comes out of the engagement hole 66), and when the cover member 4 is in the closed position, the back side protrusion portion 65 and the second arm 62 are arranged relative to each other at positions offset in the horizontal direction, as described above (as shown in Figures 14, 16, and 17).

[0042] In this embodiment, the opening contact portion is formed by the lower side of the auxiliary piece 70 when the cover member 4 is in the closed position and the inner piece 68 of the rear surface projection 65 (particularly the lower side when the cover member 4 is in the open position). Furthermore, the opening action portion is formed by the first arm 61 (particularly the upper surface). Furthermore, the closing contact portion is formed by the tip side piece 69 of the rear surface projection 65 (particularly the upper surface when the cover 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 64).

[0043] Furthermore, in this embodiment, the cover member 4 and the interlocking member 6 are configured not to interfere with each other when the cover member 4 is moved 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 positioned below, is positioned out of the path of the rear surface projection 65 of the cover member 4, which moves between the open position and the closed position. Therefore, the cover member 4 can be moved to the open position without interlocking the interlocking member 6, for example by placing a hand directly on the cover member 4.

[0044] Furthermore, as shown in Fig. 25, the trash cans 1 of this embodiment are configured so that they can be stacked (nested) one above the other 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). As shown in Fig. 26, the trash cans 1 are configured so that they do not have the bag stopper member 53 attached (in Fig. 26, only the interlocking member 6 and the pedal 5 are attached to the container body 2), and can be nested, allowing for more efficient storage, etc.

[0045] 27, the trash cans 1 of this embodiment are configured so that they can be connected to each other when placed side by side. That is, as shown in FIG. 2, a horizontal connecting portion 73 is provided on the outer surface of one of the long side wall portions 13 of the container body 2. Furthermore, as shown in FIG. 1 and other figures, a horizontally connected portion 74 that is connected to the horizontal connecting portion 73 is provided on the outer surface of the other long side wall portion 13. The horizontal connecting portion 73 and the horizontally connected portion 74 are configured so that they can be attached and detached by being displaced relative to each other in the vertical direction, and in the connected state, relative displacement in the horizontal direction between the connected trash cans 1 is prevented.

[0046] As described above in detail, according to this embodiment, when the lid member 4 is in the closed position, the rear projection 65 and the second arm 62 are positioned at positions offset from each other in the horizontal direction. Therefore, when the lid member 4 is in the closed position, the interlocking member 6 including the second arm 62 (second hook 64, etc.) can be configured not to face the upper surface of the rear projection 65 (tip piece 69, etc.). This configuration makes it possible to avoid, for example, a situation in which the lid member 4 gets caught on the interlocking member 6 when removing the lid member 4 in the closed position from the container body 2. Furthermore, when attaching the lid member 4 to the container body 2 to which the interlocking member 6 is attached, it is possible to avoid a situation in which the interlocking member 6 interferes with the attachment of the lid member 4.

[0047] On the other hand, when the cover 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 side piece 69 of the back side protrusion portion 65.Therefore, even if the cover member 4 and the interlocking member 6 are not connected, when the operation of the pedal 5 is released (the interlocking member 6 is displaced downward), the second hook portion 64 of the second arm 62 abuts against the tip side piece 69 of the back side protrusion portion 65, and an external force is applied to the cover member 4 toward the closed position, thereby establishing an interlocking mechanism between the pedal 5, the interlocking member 6, and the cover member 4. Therefore, when assembling the trash can 1, the lid member 4 can be linked to the operation of the pedal 5 simply by attaching it to the container body 2 (by fitting the shaft portion 23 of the lid member 4 into the shaft hole 25 of the container body 2), which improves the workability of assembling the trash can 1 compared to a configuration that requires, for example, not only attaching the lid member 4 to the container body 2 but also connecting it to the linking member 6. It can also improve the workability when it becomes necessary to remove the lid member 4 from the container body 2.

[0048] Furthermore, when the pedal 5 is operated to place the lid member 4 in the open position, even if the lid member 4 is pulled upward or otherwise displaced in a direction that would cause it to come off the container body 2, the second hook portion 64 of the second arm 62 comes into contact with the tip piece 69 of the back surface side protrusion 65, thereby restricting such displacement. Therefore, for example, it is possible to prevent the lid member 4 from accidentally falling off, such as when the pedal 5 is operated forcefully and the lid member 4 is forcefully moved to the open position, causing the lid member 4 to come off the container body 2 in reaction.

[0049] In this embodiment, when the lid member 4 is moved from the closed position to the open position without operating the pedal 5, there is no interference between the lid member 4 and the interlocking member 6. Therefore, when moving the lid member 4 from the closed position to the open position by directly placing a hand on it without operating the pedal 5, it is possible to avoid situations 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, and therefore the lid member 4 can be moved to the open position relatively easily. This improves operability when moving the lid member 4 to the open position by directly placing a hand on it.

[0050] In this embodiment, the second arm 62 is composed of a first hook 63 that protrudes upward from the tip of the first arm 61 and a second hook 64 that protrudes from the tip of the first hook 63 toward the center in the longitudinal width direction of the extending portion 34, and when the pedal 5 is operated to place the cover member 4 in the open position, the first hook 63 is inserted into the locking hole 66 of the back surface projection 65, and the lower surface of the second hook 64 is arranged opposite to the upper surface of the tip surface 69. In other words, when the pedal 5 is operated to place the cover member 4 in the open position, the second hook 64 of the second arm 62 and the first arm 61 are arranged vertically, and the tip surface 69 and part of the inner surface 68 of the back surface projection 65 are arranged between the second hook 64 and the first arm 61. This configuration allows the parts of the interlocking member 6 that apply force to the cover member 4 toward the open position and the closed position (first arm 61 and second hanging portion 64), and the parts that receive force from the interlocking member 6 toward the open position and the closed position (rear side protrusion portion 65) to be configured as compactly as possible.

[0051] Furthermore, the first arm 61 of the interlocking member 6 extends in a direction along the rotation axis 24 of the cover member 4 (substantially parallel to the rotation axis 24). This increases the range over which the first arm 61 can come into contact with the auxiliary piece 70 and the inner piece 68 of the back-side protruding piece 65 (contact along a line rather than a point), and when the pedal 5 is operated to place the cover member 4 in the open position, the first arm 61 can reliably come 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 cover member 4, even a slight misalignment between the first arm 61 and the auxiliary piece 70 or inner piece 68 can eliminate the sliding contact therebetween when the cover member 4 is in the open position. Alternatively, when the first arm 61 is tilted relatively greatly with respect to the rotation axis 24, the cover member 4 can be prevented from being pulled to one side or the other in the direction along the rotation axis 24, making it difficult to rotate. This can improve operability when operating the pedal 5 to place the cover member 4 in the open position. In particular, when the contact area between the auxiliary piece 70 and inner piece 68 of the first arm 61 increases, damage to the first arm 61, auxiliary piece 70, and inner piece 68 can be more reliably prevented.

[0052] In addition, the lifting base portion 31 of the interlocking member 6 is provided along the rear sidewall portion 14b of the container body 2 and is disposed so as to abut against or be close to the outer surface of the rear sidewall portion 14b. Furthermore, the arm portion 35 protrudes outward from the tip of the extension portion 34 toward the outside of the container body 2. This minimizes the possibility of the interlocking member 6 reducing the volume of the container body 2. Furthermore, for example, when stacking (nesting) trash cans 1 with the lid members 4 in the open position, or when nesting container bodies 2 with the interlocking member 6 attached but the lid members 4 not attached, the interlocking member 6 can minimize the interference with nesting, thereby improving nesting efficiency and, ultimately, the efficiency of transporting and storing the trash can 1 (container body 2).

[0053] Furthermore, the cover members 4 are provided in pairs, and the lifting / lowering base portion 31 of the interlocking member 6 extends vertically between the pair of cover members 4, and the extension portion 34 is provided to extend to a position near each rotation shaft 24 of the pair of cover members 4. This allows the pair of cover members 4 to be opened and closed simultaneously with one interlocking member 6, simplifying the structure of the interlocking member 6. Furthermore, because the lifting / lowering base portion 31 is provided between the pair of cover members 4, when a pair of cover members 4 are provided, the structure of the interlocking member 6 can be simplified and the interlocking members 6 can be arranged in a balanced manner. Furthermore, because the extension portion 34 extends to a position near the rotation shaft 24 of the cover member 4, the arm portion 35 (first arm 61 and second arm 62) provided at the tip of the extension portion 34 also abuts against the back-side protruding piece 65 and the auxiliary piece 70 in a position near the rotation shaft 24 of the cover member 4. Therefore, the stroke amount of the interlocking member 6 when opening and closing the cover member 4 can be made as small as possible, thereby improving the operability of the pedal 5 (reducing the stroke amount of the pedal 5 when placing the cover member 4 in the open position, improving the response speed of opening and closing the cover member 4 in response to operation of the pedal 5, etc.).

[0054] In addition, the rear surface side protrusion 65 is provided with an engagement hole 66 through which the second arm 62 is inserted when the pedal 5 is operated to place the lid member 4 in the open position. This makes it possible to efficiently avoid interference between the second arm 62 (second hook 64) and the rear surface side protrusion 65 (tip side piece 69) when the pedal 5 is operated to place the lid member 4 in the open position. This makes it possible to shorten the time from when the pedal 5 is released until the second hook 64 comes into contact with the tip side piece 69 and the lid member 4 is displaced to the closed position (improving the response speed of the lid member 4), when the pedal 5 is operated to place the lid member 4 in the open position. This makes it possible to improve the operability of opening and closing the lid member 4 using the pedal 5.

[0055] The present invention is not limited to the above-described embodiment, and may be implemented as follows: Of course, other applications and modifications not exemplified below are also possible.

[0056] (a) In the above embodiment, the arm portion 35 (first arm 61) protrudes from the end of the extension portion 34 to the outside of the container body 2, perpendicular to the extension portion 34. However, it may also protrude from the end of the extension portion 34 to the inside of the container body 2, perpendicular to the extension portion 34. However, by having the arm portion 35 (first arm 61) protrude from the end of the extension portion 34 to the outside of the container body 2, perpendicular to the extension portion 34, as in the above embodiment, the arm portion 35, the backside projection 65, and the auxiliary piece 70 can be disposed outside the storage section 11. This prevents the arm portion 35, the backside projection 65, and the auxiliary piece 70 from interfering with the contents when the lid member 4 is in the closed position. Furthermore, when trash cans 1 are nested with each other with the lid member 4 in the open position without operating the pedal 5, it prevents the backside projection 65 of the lower trash can 1 from interfering with the upper trash can 1.

[0057] Furthermore, in the above embodiment, the first arm 61 extends parallel to the rotation axis 24 of the cover member 4, but this is not a limitation and the first arm 61 may be configured so that when the interlocking member 6 rises in response to operation of the pedal 5, the first arm 61 comes into contact with the auxiliary piece 70 and the inner piece 68 of the cover member 4, thereby applying an external force to the cover member 4 toward the open position. Furthermore, the cross-sectional shape of the first arm 61 is not a limitation and can be changed as appropriate. However, by configuring the first arm 61 so that the portions of the first arm 61 that can come into contact with the auxiliary piece 70 and the inner piece 68 are curved and the first arm 61 extends parallel to the rotation axis 24 of the cover member 4, the cover member 4 can be rotated and displaced more smoothly.

[0058] In addition, the shape of second arm 62 is not particularly limited, as long as it is configured so that when operation of pedal 5 is released and interlocking member 6 descends, it comes into contact with tip piece 69 of cover member 4 and can apply an external force to cover member 4 toward the closed position (so that when cover member 4 is in the open position due to operation of pedal 5, second arm 62 is positioned opposite the upper surface of back surface protrusion 65). For example, second arm 62 may be configured to extend upward from the tip of first arm 61 at an angle toward the center of extension portion 34.

[0059] Furthermore, the shape of the part of the cover member 4 that comes into contact with the arm portion 35 and applies an external force to the open position or the 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 underside of the top wall portion 21 of the cover member 4, causing the cover member 4 to be displaced to the open position.

[0060] (b) In the above embodiment, when the pedal 5 is operated to place the cover member 4 in the open position, the second hook portion 64 of the interlocking member 6 and the first arm 61 are arranged one above the other, and the back side protrusion portion 65 (tip side piece 69 and inner piece 68) is arranged between the second hook portion 64 and the first arm 61. However, this configuration is not particularly limited to this, and it is sufficient that the cover 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 cover member 4 when the cover member 4 is lifted from the closed position (for example, displaced toward the open position) without operating the pedal 5.

[0061] 28 and 29, the lid member 82 of the trash can 81 includes a first protrusion 83 and a second protrusion 84 (instead of the rear protrusion 65 and auxiliary piece 70 of the above embodiment) that protrude downward from the underside of the lid member 82 in the closed position and are spaced apart vertically when the lid member 82 is in the open position, and an auxiliary piece 85 that connects the side edges of the first protrusion 83 and the second protrusion 84 that are located on the central side in the width direction of the lid member 82. Furthermore, the arm portion 87 of the interlocking member 86 is composed of a first arm 89 that protrudes outward from both ends of the extension portion 88, perpendicular to the extension portion 88 (extending parallel to the rotation axis of the lid member 82), and a second arm 90 that protrudes downward from the tip of the first arm 89. In addition, when the pedal is operated to place the cover member 82 in the open position, the second arm 90 (its lower end) is positioned opposite the upper surface of the second protrusion portion 84 (the first arm 89 and the second arm 90 are positioned between the first protrusion portion 83 and the second protrusion portion 84).

[0062] When the cover member 82 is in the closed position, the upper surface of the first arm 89 and the lower side of the auxiliary piece 85 are arranged opposite to each other (in this example, they are in contact with or close to each other). Then, as shown in FIG. 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 cover member 82 is displaced toward the open position. Thereafter, the first arm 89, which was in sliding contact with the auxiliary piece 85, comes into sliding contact with the lower surface of the first protruding piece 83, and the first protruding piece 83 is pressed upward by the first arm 89, and the cover member 82 is set to the open position. The second protruding piece 84 is provided with a hole 91 to avoid interference with the second arm 90 when the cover member 82 is rotated and displaced.

[0063] 28, when the cover member 82 is in the open position due to pedal operation, the second arm 90 is arranged to face the upper surface of the second protrusion 84, as described above. Furthermore, when the pedal operation is performed to place the cover member 82 in the open position and then the pedal operation is released, the lower end of the second arm 90 comes into contact with the upper surface of the second protrusion 84 as the interlocking member 86 moves downward, and an external force is thereby applied to the cover member 82 toward the closed position. As the cover member 82 in the open position tilts to some extent toward the closed position, the cover member 82 is displaced to the closed position due to its own weight.

[0064] Furthermore, when the cover member 82 is in the closed position, the second protrusion 84 (and the first protrusion 83) and the arm 87 are positioned at positions offset in the horizontal direction relative to each other. In other words, when the cover member 82 is in the closed position, the interlocking member 86 including the arm 87 is not positioned opposite the upper surface of the second protrusion 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 protrusion 83 correspond to the opening contact portion, and the second protrusion 84 corresponds to the closing contact portion.

[0065] Even when the above-described configuration is adopted, as in 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 linking member 86 can be configured not to get caught on the lid member 82. As a result, the workability of assembling the trash can 81 can be improved.

[0066] The shapes of the arm portion 87, the first protrusion 83, and the second protrusion 84 are not particularly limited. As shown in FIGS. 30 and 31 , the second arm 90 may be omitted from the arm portion 87. When the pedal is released and the lid member 82 is in the closed position, the lower surface of the first arm 89 abuts against the upper surface of the second protrusion 84, thereby applying an external force to the lid member 82 toward the closed position. In this configuration, the hole 91 in the second protrusion 84 can be omitted. By providing the second arm 90, the gap between the arm portion 87 and the second protrusion 84 can be minimized when the pedal is operated and the lid member 82 is in the open position, thereby shortening the time from when the pedal is released until the lid member 82 begins to close. The first arm 89 may protrude inwardly from the container body 92, rather than perpendicularly protruding from the extension 88.

[0067] Furthermore, in the lid member 82 of the trash can 81 shown in FIGS. 28 and 29 (FIGS. 30 and 31), a frame wall portion 94 protruding downward from the outer periphery of a top wall portion 93 of the lid member 82 has a side portion (particularly a portion near the open end of the lid member 82) extending perpendicular to the rotation axis direction of the lid member 82, which is recessed to allow fingertips to be inserted between the side edge of the lid member 82 in the closed position and the container body 92, and a handle portion 95 is provided to allow fingertips to be hooked 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 moving it to the open position. The shape of the handle portion 95 is not particularly limited, and it may be configured, for example, to have a generally hook-shaped cross section that provides a good grip for the fingertips.

[0068] (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 links the lid members 4 and the linking member 6 and shorten the time required to open and close the trash can 1. Also, in the above embodiment, the lid members 4 are attached to correspond to the long side wall portions 13 (so that the rotation shafts 24 extend along the width direction of the long side wall portions 13), but they may also be attached to correspond to the short side wall portions 14.

[0069] Furthermore, in the above embodiment, the interlocking member 6 is attached to the short-side side wall 14 (rear-side side wall 14b) rather than to the long-side side wall 13 to which the lid member 4 is attached. However, the interlocking member 6 may be attached to the same side wall as the side wall to which the lid member 4 is attached (particularly when only one lid member 4 is attached to the container body 2). In this case, the arm portion may be, for example, a first arm serving as an opening portion extending from the extension portion 34 (formed by 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 serving as a closing portion extending horizontally from the tip of the first hook portion and substantially perpendicular to the first arm. In addition, in the above embodiment, the container body 2 is shaped like a square box. However, the shape of the container body 2 is not particularly limited and may be, for example, substantially cylindrical.

[0070] In the above embodiment, the pair of cover members 4 are configured to have different shapes (the positions at which the rear surface side protrusions 65 and the auxiliary pieces 70 are formed are different), but they may have the same shape (the rear surface side protrusions 65 and the auxiliary pieces 70 may be provided in pairs, resulting in bilateral symmetry). In this case, the cover members 4 can be standardized, which can improve workability and convenience in inventory management, etc.

[0071] Additionally, in the above 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 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 may be adopted. Furthermore, a configuration in which the lid member 4 can be set to the open position without operating the pedal 5, thereby facilitating removal of the lid member 4 from the container body 2 (for example, the shaft hole provided in the lid member 4 has a generally C-shape that opens downward when the lid member 4 is in the open position, making it easy to remove the lid member 4 in the open position) may be adopted. Note that when the pedal 5 is operated to set the lid member 4 to the open position, the second arm 62 of the interlocking member 6 gets caught on the rear-side protruding piece 65 (tip-side piece 69) of the lid member 4, preventing removal of the lid member 4 from the container body 2.

[0072] (d) The shapes and arrangements 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 can be displaced relative to one another. However, considering the ease of manufacturing the trash can 1 and the cost, it is desirable to minimize the number of parts. Furthermore, the pedal 5 and the interlocking member 6 may be configured to protrude outward from the outer circumferential surface of the container body 2. However, in order to save space when installing 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 circumferential surface of the container body 2. Furthermore, as in the above embodiment, the portion of the short-side sidewall 14 corresponding to the upper portion of the operation storage portion 48 (up to or near the upper edge of the short-side sidewall 14) is recessed inward from the container body 2. This makes it easier to check the position of the operation portion 41 of the pedal 5 from above and improves the strength of the short-side sidewall 14.

[0073] In addition, in the above embodiment, the operating member that the user operates to open the trash can 1 is embodied as a pedal 5 that is intended to be operated with the toes, but it is not limited to this configuration and can also be applied to a handle, button, etc. that is intended to be operated by hand.

[0074] Furthermore, in the above embodiment, a pair of (two) lid members 4 are configured to be opened and closed using one interlocking member 6 and one pedal 5. However, an interlocking member and pedal may be provided for each lid member 4. For example, a pair of left and right pedals may be provided adjacent to each other, and 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 may be provided, so that pressing one of the left and right pedals opens one lid member, and pressing both pedals opens both lid members. Furthermore, for example, when there are three or more lid members, the device may be configured to include an interlocking member and pedal that open and close multiple lid members at once, and an interlocking member and pedal that open and close a single lid member other than the multiple lid members.

[0075] Additionally, although the interlocking member 6 has a symmetrical shape in the above embodiment, it may have an asymmetrical shape. For example, in response to the pedal 5 being provided at a position shifted to the right of the widthwise center of the container body 2, the lifting base portion 31 may also be provided at a position shifted to the right of the widthwise center of the interlocking member 6 (the extension portion 34 extending leftward from the lifting base portion 31 may have different extension lengths from the extension portion 34 extending rightward). Furthermore, for example, in a configuration in which one of the pair of lid members 4 has a different area in a plan view (different weight), the position of the lifting base portion 31 in the widthwise direction of the interlocking member 6 may be set according to the balance of the pair of lid members 4.

[0076] (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, polyamide, etc. Furthermore, the interlocking member 6 is made by bending a metal rod, but it may also be made of a resin material, etc.

[0077] Furthermore, in the above embodiment, the trash can 1 is embodied as a container with a lid, but it can also be used as a storage box for storing and keeping items other than trash (for example, balls, toys, miscellaneous goods, materials, etc.). In addition, in the above embodiment, it is configured so that trash cans 1 with the lid members 4 in the open position can be nested together, or so that container bodies 2 with the lid members 4 removed can be nested together, or so that trash cans 1 can be simply connected side by side by a locking structure, but it is also possible to apply this to trash cans 1 that do not allow these operations.
