Abstract

A closure for a waste receptacle is provided. The closure comprises a moveable component mounted to the closure for movement between a closed position, wherein the moveable component prohibits waste from entering the waste receptacle and an open position wherein the moveable component facilitates the entry of waste into the waste receptacle. A motor is coupled to the moveable component and configured to move the moveable component between the open position and the closed position. A sensor is adapted to transmit a signal when waste is proximal or contacting the closure, wherein the sensor communicates with the motor to move the moveable component between the open position and the closed position to deposit the waste into the waste receptacle.

Claims

1. A closure for a waste receptacle comprising:

a first moveable component mounted to said closure for movement relative to the closure between a closed position wherein said first moveable component prohibits waste from entering the waste receptacle, and an open position wherein said first moveable component facilitates the entry of waste into the waste receptacle;

a second moveable component mounted to said closure for movement relative to the closure between a closed position wherein said second moveable component prohibits waste from entering the waste receptacle, and an open position wherein said second moveable component facilitates the entry of waste into the waste receptacle;

a motor coupled to both of said first and second moveable components and configured to move said moveable components relative to the closure between said open position and said closed position, the motor having an output shaft, the closure including a rod attached to the output shaft of the motor such that rotational movement of the output shaft causes corresponding rotational movement of the rod; and

a sensor adapted to transmit a signal when waste is proximal to or contacting said closure, wherein the sensor communicates with the motor to move said first and second moveable components from said open position toward said closed position to deposit the waste into the waste receptacle, wherein the closure defines an aperture through which the waste is inserted.

2. The closure of claim 1, wherein said first moveable component is a door, and said door is configured to expose said aperture to facilitate the entry of waste into the waste receptacle in the open position of said door, and conceal said aperture to prohibit waste from entering the waste receptacle in the closed position of said door.

3. The closure of claim 2, wherein said door is pivotably coupled to said closure to pivot between said open position and said closed position.

4. The closure of claim 1, wherein said second moveable component is a tumbler that is rotatably coupled to said closure, wherein said tumbler is configured to rotate to the open position to facilitate the entry of waste into the waste receptacle.

5. The closure of claim 1, wherein said sensor is a motion sensor adapted to sense waste proximal to said closure.

6. The closure of claim 1, wherein said sensor is a weight sensor adapted to sense waste contactinq said closure.

7. The closure of claim 1, wherein both the first and second moveable components are operatively connected to the rod.

8. The closure of claim 7, further comprising a gear having teeth attached to the rod, and wherein:

the first moveable component is a door having gear teeth; and

rotational movement is transferred from the motor to the door through engagement of the teeth of the gear attached to the rod with the gear teeth of the door.

9. The closure of claim 8, wherein:

the second moveable component is a tumbler having a plurality of arms extending from the rod; and

at least one of the plurality of arms prohibits waste from entering the waste receptacle when the tumbler is in the closed position.
