  • Patent number: 4643380
    Abstract: A form having a tapered enclosure with open end, the top being larger than the bottom having handles, or handholes, on each side. The enclosure is placed into a plastic trash bag with the top lapped over the upper lip, leaving the handles exposed. A bottom pan having a strap retained across the underside is nested into the bag covered enclosure forming a structured base and the straps is attached to the handles, or holes, with integral hooks. Trash is placed inside the assembly and compressed manually against the sides of the enclosure and the base. A lid is placed on the top of the assembly for storage and transportation and the bag is removed by disconnecting the straps along with the pan, slipping the enclosure upward out of the bag. As the enclosure is tapered inversely, the compacted trash remains inside the bag sliding easily from the form.
