A trash can system and component elements are described. Folded or interfolded trash bags are provided in a container beneath a flexible insert. The flexible insert provides separation between a trash bag in an operative position within the trash can, and provides support to the container against the pulling operation performed by a user to pull a full trash bag out of the container and dispense a new, refill trash bag from the container. According to another exemplary embodiment, folded or interfolded trash bags are provided in a tray which slidably connect to a lid associated with a box disposed in the trash can.
