Abstract: A shaped elongate strap enables a plastic grocery bag to be used for trash disposal in a vehicle. It has a shaped headrest post-gripping top portion at one end and forward and rearward grocery bag handle grips at the other end. The ends are connected by a flexible corrugated strip. The orientation of the corrugations and the spacing of the grips keep the strap from twisting and the grips forward of the back of the seat.
