A foldable frame for containers has a polygonal base mount made of studs and an upper mount parallel to the base mount made of studs. The polygonal base mount and the upper mount are connected together by means of columns of equal length. The columns are formed of at least two sections of the same length, and the adjacent sections are joined together by a hinged member, the hinged member containing a first bushing connected to a slider movably disposed in the cavity of the first section, a second bushing having common axle with the first bushing and secured to the locking member arranged in the inner cavity of the adjacent second section, with a hinge pin provided in the bushings.
