Abstract
A spread strap flexible bulk container comprises a flexible bulk container having a plurality of panels seamed together to form a substantially square container with vertical seams connecting the panels located equidistant between adjacent corners of the container as opposed to the seams being located at the corners. Lift straps for supporting the container are attached at opposed ends to the container beginning at adjacent seams and extending diagonally upwardly to loop over the corners of the container. Bridge panel may be inserted into the container and each bridge panel attached to a single panel or a portion of a single panel.
Claims18
A flexible container for receiving, transporting, and storing flowable materials comprising:
- two side panels each having four edges;
- one elongate panel having a pair of opposed elongate edges and a pair of opposed shorter edges and seamed along the length of said elongate edges to three sides of each of the side panels to form an upwardly open container;
- a top panel having four corners and seamed to the remaining edge of each of the side panels and to the opposed shorter edges of the elongate panel such that the corners of the top panel are attached at points equidistant from the seams connecting the side panels to the elongate panel;
- and
- at least one strap having two opposed ends with said opposed ends of the strap attached to the container at adjacent seams connecting a side panel to the elongate panel with a center portion of the strap extending above the top panel to form a loop.
A flexible container for receiving, transporting, and storing flowable materials comprising:
- two side panels each having a bottom, a top, and two side edges;
- one elongate panel having first and second opposed edges equal in length to the total length of the bottom and the two side edges of one side panel and third and fourth opposed shorter edges and attached along the length of said first and second opposed edges to the two side and the bottom edges of said side panels to form an upwardly open container having a substantially square shape;
- a top panel having four corners and seamed to the top edges of the side panels and the third and fourth opposed edges of the elongate panel such that the corners of the top panel are attached at points equidistant from the seams connecting the side panels to the elongate panel;
- and
- at lease one strap having first and second ends with the first end of the strap attached to the container at one of the seams connecting one of the side panels to the elongate panel and the second end of the strap attached to the container at the next adjacent seam connecting one of the side panels to the elongate panel with a center portion of the strap extending above the top panel to form a loop.
A flexible container for receiving, transporting, and storing flowable materials comprising:
- two side panels each having a bottom, top, and two side edges;
- one elongate panel having first and second opposed edges equal in length to the total length of the bottom and the two side edges of one side panel and having third and fourth opposed shorter edges and attached along the length of said first and second opposed edges to the two side and the bottom edges of said side panels to form an upwardly open container having a substantially square shape;
- a top panel having four corners and an opening in the center of said top panel for receiving and discharging flowable materials and seamed to the top edges of the side panels and the third and fourth opposed edges of the elongate panel such that the seams connecting the side panels to the elongate panel are seamed to the top panel at points equidistant from adjacent corners of the top panel;
- and
- at lease one strap having first and second ends with the first end of the strap attached to the container at one of the seams connecting one of the side panels to the elongate panel and continuing diagonally upwardly to the seam connecting the top panel to the side panels and the elongate panel and the second end of the strap attached to the container at the next adjacent seam connecting the elongate panel to one of the side panels and continuing diagonally upwardly to the seam connecting the top panel to the side panels and the elongate panel with the center portion of the strap extending above the top panel to form a loop for lifting and suspending the container.
