Folding collapsible bag

Abstract

A folding collapsible bag includes a soft collapsible bag body, a first base member and a second base member bilaterally and separately set in and affixed to the bag body for stretching the bottom side of the bag body into a planar shape, a first supporting element and a second supporting element respectively made by bending a resilient wire rod into shape and bilaterally obliquely set in and affixed to the bag body to support the periphery of the bag body in shape, and a set of matching fastening members fastenable to each other to hold the bag body in a collapsed condition when the first base member and the second base member are respectively upwardly biased toward the first supporting element and the second supporting element.

1 . A folding collapsible bag, comprising:
 a bag body made from a soft collapsible sheet material, said bag body having a top open side;   a first base member and a second base member bilaterally and separately set in and affixed to said bag body at a bottom side for stretching a bottom side of said bag body into a planar shape;   a first supporting element and a second supporting element bilaterally obliquely set in and affixed to said bag body to support the periphery of said bag body in shape;   first fastening means and second fastening means mounted inside said bag body and fastenable to each other to hold said bag body in a collapsed condition;   wherein said first base member and said second base member are respectively upwardly turnable toward said first supporting element and said second supporting element to collapse said bag body.   
     
     
         2 . The folding collapsible bag as claimed in  claim 1 , wherein said first base member and said second base member are flat plate members. 
     
     
         3 . The folding collapsible bag as claimed in  claim 1 , wherein said first base member, said second base member, said first supporting element and said second supporting element are respectively prepared from a resilient wire rod and bent into a predetermined shape. 
     
     
         4 . The folding collapsible bag as claimed in  claim 1 , further comprising a third supporting element vertically set in and affixed to said bag body between said first supporting element and said second supporting element. 
     
     
         5 . The folding collapsible bag as claimed in  claim 4 , wherein said third supporting element has a board member fixedly mounted thereon for dividing the inside space of said bag body into two compartments. 
     
     
         6 . The folding collapsible bag as claimed in  claim 5 , wherein said first fastening means comprises two first fastening members affixed to said bag body on the inside at two opposite locations; said second fastening means comprises two second fastening members respectively fixedly located on two opposite sides of said board member for the fastening of said two first fastening members. 
     
     
         7 . The folding collapsible bag as claimed in  claim 4 , wherein said third supporting element has a cord handle fixedly provided at a top side thereof. 
     
     
         8 . The folding collapsible bag as claimed in  claim 1 , wherein said first fastening means is prepared from a hook material, and said second fastening means is prepared from a loop material fastenable to said hook material. 
     
     
         9 . The folding collapsible bag as claimed in  claim 1 , wherein said first fastening means and said second fastening means are reversely arranged magnets. 
     
     
         10 . The folding collapsible bag as claimed in  claim 1 , further comprising a third supporting element and a fourth supporting element vertically set in and affixed to said bag body between said first supporting element and said second supporting element in a parallel manner. 
     
     
         11 . The folding collapsible bag as claimed in  claim 10 , wherein said third supporting element and said fourth supporting element each have a board member fixedly mounted thereon for dividing the inside space of said bag body into three compartments. 
     
     
         12 . The folding collapsible bag as claimed in  claim 11 , wherein said first fastening means comprises two first fastening members affixed to said bag body on the inside at two opposite locations; said second fastening means comprises two second fastening members respectively fixedly located on the board members at said third supporting element and said fourth supporting element for the fastening of said two first fastening members.
