         8 . The adjustable container of  claim 7 , wherein the floor comprises a second unfoldable part formed along at least two second fold lines, and
 wherein in the first state, the second unfoldable part is folded, and in the second state, the second unfoldable part is unfolded.   
     
     
         9 . The adjustable container of  claim 7 , wherein each of the at least two first fold lines correspond to each of the at least two second fold lines. 
     
     
         10 . The adjustable container of  claim 7 , wherein a top side of the peripheral wall comprises a top side of the first unfoldable part, and a bottom side of the sheet-type lid directly contacts with the first unfoldable part. 
     
     
         11 . The adjustable container of  claim 7 , wherein each of the top side of the first unfoldable part and the upper opening comprises a zig-zag shape. 
     
     
         12 . The adjustable container of  claim 7 , wherein the sheet-type lid comprises a flat part and a third unfoldable part, and in the first state, the third unfoldable part is folded, and in the second state, the third unfoldable part is unfolded. 
     
     
         13 . The adjustable container of  claim 7 , wherein in the first state, a bottom side of the third unfoldable part is attached to a top side of the peripheral wall. 
     
     
         14 . The adjustable container of  claim 7 , wherein an area of a bottom side of the flat part is smaller than the second area. 
     
     
         15 . An adjustable container of  claim 7 , the adjustable container further comprises at least one string, and
 wherein each end of the string fixes at each side of the first unfoldable part,   wherein in the first state, the string provides tension to keep the first unfoldable part folded, and   in the second state, the string is ripped.   
     
     
         16 . The adjustable container of  claim 7 , the sheet-type lid further comprises perforated line between the third unfoldable part and the flat part, and
