Disclosed herein is a bin that has a first portion configured to hold at least one item therein and an adjustable second portion. The adjustable second portion is configured to couple with the first portion and slide relative to the first portion between a collapsed position and an expanded position. The collapsed position provides a minimum combined height for the first portion and the adjustable second portion in which the adjustable second portion encapsulates the first portion in order for the bin to be placed inside a receptacle. The expanded position provides a maximum combined height for the first portion and the adjustable second portion in order for the bin to interface with a mechanical device for disposing of the at least one item. The bin also includes one or more holding mechanisms for securing the bin in at least one of the collapsed and expanded positions.

A second flap encloses a top portion the second inner area. A pushbutton latch secures and releases the second flap. A hook attaches the second component to a dog leash.

A waste disposal system with a compact footprint. The waste disposal system device accepts a cassette having a length of tubular liner film. The waste disposal device and cassette can have similar cross-sectional geometry. The waste disposal device and/or cassette comprise a first wall, a second wall, and a first included angle defined therebetween between about sixty and about one-hundred twenty degrees.

A garbage box includes an opening-closing unit and a switch on a predetermined surface, the switch being a switch by which the opening-closing unit is opened. The garbage box is installed such that the predetermined surface faces a base surface with a predetermined interval from the base surface, the base surface being a floor surface or a ground surface.

A trash box is a trash box including a trash box main body in which trash is accommodated. A top surface or a side surface of the trash box main body includes an input port via which the trash is put into the trash box main body. A bottom surface of the trash box main body includes an opening-closing portion. The trash box main body is placed such that the opening-closing portion faces a reference plane that is a floor face or ground. The trash box main body is changeable in height from the reference plane.

The garbage box includes an opening-closing unit on a predetermined surface, and the garbage box is installed such that the opening-closing unit faces a base surface with a predetermined interval from the base surface, the base surface being a floor surface or a ground surface. The garbage box opens the opening-closing unit when the garbage box detects that an autonomous mobile robot has come to a predetermined position in a vicinity of an installation position of the garbage box.

Various receptacle embodiments with expandable cavities are disclosed. In some embodiments, a receptacle comprising a first and second frame with a hinge permitting the first frame to pivot about the axis defined by the hinge to expand the volume of the cavity defined by the first and second frame is disclosed. In another embodiment, a receptacle comprising a first and second frame comprising a tension gear mated into a corresponding track is disclosed, permitting lateral movement between the first and second frames to expand the volume of the cavity defined by the first and second frame is disclosed. Other disclosed embodiments comprise lid and foot pedal assemblies as well as spring assist systems and other features.

A trash can for the collection and disposal of trash is disclosed. The trash can includes a base and a separable sidewall allowing for easy removal of a bag from the trash can by lifting the sidewall around the bag, rather than lifting the bag through the top of the trash can. The base of the trash can is connected to straps with a handle positioned between the straps. The handle may be engageable with the sidewall so that the straps hold the sidewall and base together. The handle allows for convenient carrying of the base. The separable sidewall includes a bottom opening defined by the sidewall without a constriction in the width of a base end of the sidewall. The base includes a perimeter wall to inhibit material from escaping the base. The trash may have an outwardly tapered shape to increase the overall volume of the trash can.

A cart lifter assembly is provided that is adapted to be mounted to an intermediate refuse collection container that includes a scissors-type extension assembly for moving the lifter between a first/retracted and a second/extended position. The scissors extension assembly further comprises an elongated channel member configured to be secured to the wall of the intermediate container; a mounting block slidably received in the elongated channel member; first second, third and fourth scissor arms; and a bracket configured to be fixedly mounted to the wall of the intermediate container in spaced relationship to the elongated channel member. A rotary actuator is secured to the bracket and has a rotatable shaft extending from opposite ends thereof, for moving the lifter relative to the intermediate container between the first/retracted position and the second/extended position, with one end of the second scissor arm being removably secured to the rotatable shaft.
