Folding container with adjustable height

Abstract

An exemplary folding container ( 20 ) includes a main body ( 22 ). The main body includes four fixed sidewalls ( 221 ), four folding sidewalls ( 222 ), and a bottom wall. The four fixed sidewalls, the bottom wall, and optionally the four folding sidewalls cooperatively form a receptacle. A size of the receptacle is adjustable according to a selected position of the four folding sidewalls.

1 . A folding container comprising:
 a main body, the main body comprising four fixed sidewalls, four folding sidewalls, and a bottom wall; wherein   the four fixed sidewalls and the bottom wall, and optionally the four folding sidewalls, cooperatively form a receptacle, a size of the receptacle being adjustable according to a selected position of the four folding sidewalls.   
   
   
       2 . The folding container as claimed in  claim 1 , wherein the four folding sidewalls are hingedly connected to the four fixed sidewalls. 
   
   
       3 . The folding container as claimed in  claim 1 , wherein each of the folding sidewalls comprises two folding portions, the folding portions being hingedly connected to each other, and a lower one of the folding portions being hingedly connected to a respective one of the fixed sidewalls. 
   
   
       4 . The folding container as claimed in  claim 1 , further comprising a cover, the cover comprising a cover body and four blocking portions, the four blocking portions being at four corners of the cover body respectively. 
   
   
       5 . The folding container as claimed in  claim 4 , further comprising a base, wherein the main body is provided on the base. 
   
   
       6 . The folding container as claimed in  claim 5 , wherein the main body and the base are integrated together as a single body. 
   
   
       7 . The folding container as claimed in  claim 5 , wherein the main body and the base separate parts attached together. 
   
   
       8 . The folding container as claimed in  claim 4 , wherein the main body further comprises a metal frame, the metal frame comprising:
 a first set of support members extending vertically along substantially an entire height of the fixed sidewalls; and   a second set of support members extending horizontally along a perimeter of the bottom wall.   
   
   
       9 . The folding container as claimed in  claim 4 , wherein each of the blocking portions comprises a right-angled structure. 
   
   
       10 . The folding container as claimed in  claim 9 , wherein a height of the blocking portion is greater than a thickness of the cover body. 
   
   
       11 . The folding container as claimed in  claim 8 , wherein the four fixed sidewalls are made from aluminum. 
   
   
       12 . The folding container as claimed in  claim 11 , wherein the folding sidewalls are made from magnetized iron. 
   
   
       13 . A folding container comprising a main body, the main body defining a box having a top opening, a size of the box being changeable by manual adjustment of movable portions of the main body. 
   
   
       14 . The folding container as claimed in  claim 13 , further comprising a cover, wherein the cover covers the opening of the box. 
   
   
       15 . The folding container as claimed in  claim 13 , wherein the main body comprises:
 four fixed sidewalls;   four folding sidewalls, each of the folding sidewalls being hingedly connected to a corresponding one of the fixed sidewalls; and   a bottom wall adjoining bottoms of the fixed sidewalls;   the fixed sidewalls and the bottom wall, and optionally the folding sidewalls, cooperatively forming five sides of the box.   
   
   
       16 . The folding container as claimed in  claim 13 , further comprising a base below and integrated with the main body, the base comprising a top surface, the main body comprising:
 four fixed sidewalls; and   four folding sidewalls, each of the folding sidewalls being hingedly connected to a corresponding one of the fixed sidewalls;   wherein the fixed sidewalls and the top surface of the base, and optionally the folding sidewalls, cooperatively form five sides of the box.   
   
   
       17 . The folding container as claimed in  claim 15 , wherein the main body further comprises a metal frame, and the metal frame comprises:
 a first set of support members extending vertically along substantially an entire height of the fixed sidewalls; and   a second set of support members extending horizontally along a perimeter of the bottom wall.   
   
   
       18 . The folding container as claimed in  claim 15 , wherein each of the folding sidewalls comprises at least two folding portions, the folding portions being hingedly connected to each other. 
   
   
       19 . The folding container as claimed in  claim 15 , wherein the fixed sidewalls are made from aluminum. 
   
   
       20 . The folding container as claimed in  claim 15 , wherein the folding sidewalls are made from magnetized iron.
