A hub assembly includes a retainer housing, a retaining member, a biasing element, and an occlusion. The retainer housing includes a wheel mounting sleeve and a pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle. The pin sleeve has a first end and a second end. The pin sleeve includes a conduit between the first end and the second end. The first end is in fluid communication with the axle bore. The retaining member and the biasing element are in the conduit. The retaining member is configured to engage a groove in an axle. The biasing element is configured to bias the retaining member towards the axle bore. The occlusion is proximate to the second end of the pin sleeve. The occlusion is configured to inhibit the retaining member from exiting the conduit at least prior to coupling the hub assembly to a wheel.

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 pet waste collection system includes a first component and a second component detachably connected to each other. The first component has a first inner area to hold a roll of dog waste bags that is formed from a solid outer cylindrical wall and a solid bottom. A first flap encloses a top portion of the first inner area and has an aperture retrieving a dog waste bag. A pushbutton latch secures and releases the first flap. A hook attaches the first component to a dog leash. The second component has a second inner area for holding a filled dog waste bag and is formed from an outer cylindrical wall including a plurality of perforations and a solid bottom. 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 refuse container lid opening device includes a lid hingedly attached to a container body for covering the container body's top opening. The lid is free of grabbable handles or protuberances but an elongated tongue descending from its underside is received in a slot in the top rim of the container body and is accessible outward of the container body. Upward movement of the tongue when the lid is closed raises the lid above the top rim of the container body to form a manually accessible gap in which a hand can be inserted to fully open the lid.
