Abstract: A system is disclosed for automatically lining a trash receptacle. The system includes a trash receptacle having a side wall portion, an open upper end and a floor portion interconnected to the side wall portion at a lower end of the receptacle. The floor portion has a slot formed therein. A holder includes a peripheral wall portion, a bottom portion interconnected to the peripheral wall portion and an opening that receives the lower end of the receptacle. The receptacle and the holder are interengaged such that the floor of the receptacle is spaced above the bottom portion of the holder to define a bag accommodating chamber in the holder. A spindle carries a roll of perforated plastic trash bags. The spindle is rotatably mounted to the holder such that the spindle extends across the holder chamber.
