Description

[Technical field]

[0001] The present invention relates to a trash can. [Background technology]

[0002] There is known a trash can in which a lid is provided at the rear end of the trash can as a pivot part so as to be rotatable relative to a trash insertion opening provided at the top of the trash can (for example, Patent Documents 1 and 2).

[0003] Furthermore, a trash can is known in which a rectangular second trash opening is provided in front of the lid of the trash can, and a flap plate for closing the second trash opening is arranged to be freely rotatable toward the bottom of the lid and is given a biasing force in the closing direction (Patent Document 3).

[0004] On the other hand, a trash can in which a lid is pivotally attached to the rear end of the trash can and can rotate freely around a trash opening at the top of the trash can body, with a gasket interposed between the lid and the trash can body, is also known (Patent Document 4). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2003-112801 [Patent Document 2] Patent Publication 2002-167001 [Patent Document 3] Patent Publication No. 2018-90363 [Patent Document 4] Patent Publication No. 2018-090364 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] The trash can described above is convenient for throwing in large trash because the trash opening at the top of the trash can is widely exposed when the lid is opened, but it is troublesome to have to open the lid wide every time even to throw out small trash.

[0007] In the above case, assuming a kitchen where this type of trash can is often used, the fact that the trash opening is widely exposed by opening the lid even when throwing away small trash means that the food waste thrown inside is exposed, which not only looks unsightly but also causes undesirable problems such as the emission of odors.

[0008] In addition, when throwing out small trash, the above problem can be solved by opening the lid only a little and throwing the trash in through the gap between the lid and the trash can body. However, in this case, the trash tends to be concentrated at the front of the trash can body, resulting in the problem that the internal volume cannot be fully utilized.

[0009] In contrast, the trash can described in Patent Document 3 has a second trash opening at the front of the lid, so that when throwing out small trash, it is possible to throw it out through this second trash opening without having to open the lid all the way each time, which has the effect of improving usability and preventing unsightly appearance.

[0010] On the other hand, in this trash can, the flap plate for closing the second trash opening is freely rotatable toward the bottom of the lid body and merely exerts a biasing force in the closing direction. Therefore, the flap plate does not fit tightly with the edge of the trash opening at the point where it comes into contact, and it was desired to prevent odors from leaking out from there.

[0011] One possible means for achieving this would be to provide a ring-shaped gasket at the point where the waste inlet comes into contact with the flap plate around its periphery; however, because the waste inlet and flap plate are rectangular, if the gasket changes and deforms over time, it may not adhere well to the corners where it comes into contact, and the gasket may become twisted at that point, causing problems when opening and closing.

[0012] Furthermore, in the case of a trash can that has a gasket between the lid and the trash can body, except for the case of the trash can described in Patent Document 4, in which one end is a hinge portion and the other end is a lock portion and the lid is closed with strong pressure, in a pedal-opening trash can in which the lid is pushed up by a lifting member that rises and falls with the up and down movement of a pedal provided below the trash can, the lid is closed only by its own weight, so there is a risk that simply fitting the gasket into the groove will not provide a tight fit. [Means for solving the problem]

[0013] The present invention has been created with the objective of providing a trash can which overcomes the problems of the prior art described above, and which has a lid which is pivotally attached to the rear end of the trash can and which is pivoted about a trash inlet provided at the top of the trash can body, and which is pushed up by a lifting member which rises and falls with the up and down movement of a pedal provided below the trash can; a second trash inlet is provided in front of the lid, and a flap plate for closing the second trash inlet is pivotally attached toward the bottom of the lid, and a biasing force is applied in the closing direction, and the airtight means for closing the lid and the trash can body, and the lid and the flap plate, are configured as follows (1) and (2): Configuration (1): A first packing made of an elastic material is interposed at the contact point of the back surface of the lid with the top end of the trash can body when closed, said packing is in the form of a flat, annular, thin plate that covers the top end of the trash can body and has an attachment edge raised from its inner peripheral end for attachment to the back surface of the lid, said attachment edge of said packing is fitted into a groove provided on the back surface of the lid so that the parts other than the attachment edge are flexible relative to the lid, and said flexible part comes into contact with the top end of the trash can body when the lid is closed, which is an airtight means between the lid and the trash can body. Configuration (2): The second garbage inlet is rectangular with rounded corners, and a flat rectangular annular groove with rounded corners is formed on the back side of the periphery of the second garbage inlet. A second annular gasket made of an elastic material and having a cross-sectional dimension larger than the inner dimension of the groove is forcefully inserted into the groove, thereby forming an airtight means between the lid body and the flap plate, whereby the flap plate abuts against the gasket when the flap plate is closed.

[0014] In addition, the trash can of claim 2 is characterized in that when the first gasket is fitted into a groove provided on the back surface of the lid, a protrusion on the side of the mounting edge overcomes a protrusion in the groove provided on the back surface of the lid, thereby preventing the first gasket from coming loose. Effect of the Invention

[0015] According to the trash can of the present invention, a second trash opening is provided in front of the lid, so that when throwing away small trash, it is not necessary to open the lid wide each time, but the trash can can be thrown away through this second trash opening, making the trash can easy to use and preventing unsightly appearance and the emission of odors.

[0016] In this case, the flap plate that closes the second garbage inlet is arranged so as to be freely rotatable toward the bottom of the lid body and is biased in the closing direction 4, so that it can be opened with one touch by pushing it down against the biasing force, thereby achieving the effect of enabling one to simply open the flap plate with the hand holding the garbage and throw away the garbage.

[0017] The second garbage inlet is rectangular with rounded corners, and a flat rectangular annular groove with rounded corners is formed on the back side of the periphery of the second garbage inlet. A second annular gasket made of an elastic material and having a cross-sectional dimension larger than the inner dimension of the groove is forcefully fitted into the groove. Therefore, the gasket has no corners and contacts the periphery of the garbage inlet evenly all around, so that adhesion is not hindered even if the gasket deforms over time, and since the gasket does not twist, there is no risk of it interfering with the fit when opening and closing.

[0018] On the other hand, a first gasket made of an elastic material is interposed at the contact point of the back surface of the lid with the top end of the trash can body when closed, and the gasket is in the form of a flat, annular, thin plate that covers the top end of the trash can body, and has an attachment edge raised from its inner edge for attachment to the back surface of the lid, and the attachment edge of the gasket is fitted into a groove provided on the back surface of the lid, making the parts other than the attachment edge flexible relative to the lid, and since the flexible part comes into contact with the top end of the trash can body when the lid is closed, it can be expected that the gasket will reliably fit tightly against the top end of the trash can body, even in a pedal-opening trash can in which the lid is closed only by its own weight.

[0019] As described above, the trash can of the present invention provides reliable airtightness between the lid and the trash can body, and between the lid and the flap, preventing odors from leaking out. [Brief description of the drawings]

[0020] [Figure 1] FIG. [Diagram 2] FIG. [Diagram 3] Same as above, cross-sectional view. [Figure 4] FIG. [Diagram 5] FIG. [Figure 6] FIG. [Figure 7] FIG. [Figure 8] FIG. 2 is a perspective view of the lid from the back side with the packing removed. [Figure 9] FIG. 2 is a perspective view of the lid from the back with the packing removed. [Figure 10] FIG. 4 is an enlarged cross-sectional view of a portion of the lid showing the first gasket attached to the lid; BEST MODE FOR CARRYING OUT THEINVENTION

[0021] The present invention is applied to a known pedal-operated trash can in which a lid is pivotally attached to a trash inlet at the top of the trash can, with the rear end of the trash can as a pivot, and the lid is pushed up by a lifting member that moves up and down in response to the up and down movement of a pedal attached below the trash can.

[0022] In the drawing, reference numeral 1 denotes the main body of the trash can made of a plastic material. The trash can main body 1 is a container-like shape with a rectangular cross section and a bottom, with a trash inlet 6 open at the top, and a lid 10 is attached to the trash inlet so as to be able to rotate freely. The lid 10 is attached to the end of the trash inlet 6 with a pivot part 11 so as to be able to be opened and closed, and is provided with the following mechanism that allows the user to open and close it by operating a pedal.

[0023] That is, a lifting rod 5 is disposed vertically at the rear of the trash can body 1 so as to be movable up and down, and the lower end of the lifting rod is connected by a pivot part 4 to the rear end of a rotating rod 3 which rotates up and down like a seesaw with a pivot part 7 provided on the underside of the bottom of the trash can body as a fulcrum, and the abutment part 5A at the upper end of the lifting rod is disposed so as to abut against an abutment part 11A provided near the pivot part 11 on the underside of the lid body 10 (see Fig. 3). A pedal 2 which can be operated by foot protrudes from the lower front of the trash can in front of the rotating rod 3, and when the pedal is lowered, the lifting rod 5 rises and pushes open the lid body 10 (see Fig. 2).

[0024] The lid 10 has a first packing 13 interposed at the contact point of the back surface with the upper end of the trash can body 1 when closed. The first packing 13 is made of an elastic material and has a flat annular thin plate shape that covers the upper end of the trash can body 1, and an attachment edge 13A for attachment to the back surface of the lid 10 is raised from the inner peripheral end. On the other hand, an annular groove 12 sandwiched between two protruding annular ridges is provided on the back surface of the lid 10, and the first packing is fixed to the back surface of the lid by fitting the attachment edge 13A of the first packing 13 into this groove. In this case, as shown in FIG. 10, the first packing 13 is flexible with respect to the lid body at the other points than the attachment edge 13A, and the flexible part is in contact with the upper end of the trash can body when the lid is closed. In this case, the protrusion 13B provided on the side of the attachment edge 13A is made to go over the protrusion 12A provided in the groove 12 to prevent the first packing 13 from coming off.

[0025] In the drawing, reference numeral 14 denotes a second garbage insertion opening provided in the lid body 10, which opens in the front third of the lid body 10. The second garbage insertion opening 14 is closed by a flap plate 16 located on the back side of the lid body 10. The flap plate 16 is provided at a pivot part 18 so as to be able to rotate toward the bottom of the lid body 10, and a biasing force in the closing direction is applied by a torsion coil spring (not shown).

[0026] The second garbage inlet 14 is rectangular with rounded corners, and a groove 15 is formed on the back side of the periphery of the second garbage inlet, sandwiched between two annular ridges having a rectangular planar shape with rounded corners. A second annular gasket 17 made of an elastic material and having a cross-sectional dimension larger than the inner dimension of the groove is forcefully fitted into the groove, so that the flap plate 16 abuts against the gasket when the flap plate is closed.
