Abstract
Abstract In the construction of a collapsible receptacle there is provided a length of fabric material and a length of webbing material formed from the same material as the length of fabric material. A plurality of lift loops formed from length of webbing material are positioned at spaced points along the length of fabric material with the lower ends of the lift loops located more than a predetermined distance above the lower edge of the material. After the lift loops are secured to the length of fabric material, the assembly is secured around the upper end of a collapsible receptacle body panel with the lift loops projecting above the upper edge of the panel. A line of stitching is used to at least partially secure the assembly to the body panel, with the line of stitching positioned at least the predetermined distance below the lowermost end of the lift loops.
