Abstract:
A folding container (10) comprises a bottom plate (11), a first ring (12), a second ring (13), a spring (14), a coating layer (15), and at least two fastening portions (16). The first ring (12) is disposed at the periphery of the bottom plate (11). The aperture of the second ring (13) is smaller than the aperture of the first ring (12). Two ends of the spring (14) are respectively connected to the first ring (12) and the second ring (13), so that a distance is maintained between the first ring (12) and the second ring (13). When the spring (14) is compressed, the second ring (13) moves and is accommodated in the inner edge of the first ring (12). The coating layer (15) covers the bottom plate (11), the first ring (12), the second ring (13) and the spring (14) to form a storage cavity (20). The at least two fastening portions (16) are symmetrically arranged on the outer side of the first ring (12), and when the second ring (13) moves to the inner side of the first ring (12), the second ring (13) is fastened and fixed.
