Abstract: A holder assembly for use with refuse bags is disclosed. The assembly includes a dish-shaped base member supporting ground engaging wheels. A frusto-conically shaped bag support removably and snugly engages the base member. The bag support is sized such that its larger end engages the base member. It is also sized such that the closed end of a refuse bag will engage the base member while the open end of the bag extends out of the support so that the bag may be folded over to engage the upper end portion of the support. The lower end portion of the support is also sized such that a full refuse bag will not engage the inner lower portion of the support. A handle is provided on the base member for moving it on the wheels. A simple pin and slot type lock is provided on the support and base member.
