Composite Storage Bin

Abstract

The present disclosure relates to a composite storage bin comprising a frame and a sack body: the frame comprises four U-shaped elbows with identical designs in length and bending for cubic contouring and multidirectional placement of the assembled frame; the sack body mounted on the assembled frame coordinates an orientation of placing the frame to deflect an opening of the sack body upward or sideways. The sack body, which is internally hung in or externally encloses the frame, has an opening around which positioning units stopped at elbows are prepared for supporting and positioning the sack body.

1 . A composite storage bin, comprising:
 a frame consisting of four U-shaped arms and being formed in cubic contouring and being able to be placed multidirectionally; and   a sack body mounted on the frame and letting an opening on the sack body facing upward or sideways,   wherein each of the four U-shaped arms is formed in identical shape and size.   
     
     
         2 - 3 . (canceled) 
     
     
         4 . The composite storage bin as claimed in  claim 1  wherein each of the four arms is provided with fastening units at both ends by which any two of the four arms are assembled. 
     
     
         5 . The composite storage bin as claimed in  claim 1  wherein the sack body is provided with two positioning units around the opening and the two positioning units are stopped at the corresponding arms for holding the sack body. 
     
     
         6 . The composite storage bin as claimed in  claim 5  wherein each of the two positioning units is an annular tube enclosing and stopped at the corresponding arm. 
     
     
         7 . The composite storage bin as claimed in  claim 5  wherein each of the positioning units is a cord tied up to the corresponding arm. 
     
     
         8 . The composite storage bin as claimed in  claim 5  wherein each of the two positioning units is a sling which circles the corresponding arm for fixing the sack body on the frame and has one end fixed at the sack body with a button or a hook-and-loop fastener. 
     
     
         9 . The composite storage bin as claimed in  claim 8  wherein the sling is extended and formed from one edge of the opening of the sack body directly. 
     
     
         10 . The composite storage bin as claimed in  claim 5  wherein each of the two positioning units is extended and bent from edges of the opening of the sack body directly and stopped and formed at the corresponding arm. 
     
     
         11 . The composite storage bin as claimed in  claim 1  wherein the sack body is provided with a cover lid at the opening which is shielded by the cover lid. 
     
     
         12 . The composite storage bin as claimed in  claim 11  wherein the cover lid is extended and formed from one edge of the opening of the sack body directly. 
     
     
         13 . The composite storage bin as claimed in  claim 11  wherein the cover lid is tightly sealed at the sack body with a sealing unit at the junction of the cover lid and the sack body. 
     
     
         14 . The composite storage bin as claimed in  claim 13  wherein the sealing unit can be a zipper, a seal strip or a hook-and-loop fastener by which the cover lid and the sack body are tightly sealed. 
     
     
         15 . The composite storage bin as claimed in  claim 11  wherein the cover lid comprises a window from which the interior of the sack body is checked. 
     
     
         16 . The composite storage bin as claimed in  claim 1  wherein the sack body comprises bores at corners through which the sack body encloses the elbows for supporting.
