Abstract
To support the trash bag for filling, a conical frustum trash bag support having an open circular top and bottom is placed on the ground in inverted position with its top, which is the smaller of the top and bottom, down and the trash bag is pulled over its larger side and draped downwardly, after which, conical frustum and trash bag are reversed so that the trash bag is open end up and the conical frustum is right side up, and a ring is dropped over the top so that it rests on the bag at a location part way down from the top of the frustum to hold the bag in place with the upper end of the bag draped over the ring. The conical frustum is then filled with trash. To remove the conical frustum from the bag, the ring is pulled upwardly to straighten the bag and the conical frustum is pulled up, with the trash causing the bag to remain on the ground as the ring and conical frustum are removed, thus leaving the filled bag ready for disposal.
