Abstract: An assembleable container for storing a liquid includes an upper main body having a first connector and a lower main body having a second connector. The first connector has a convex portion or a concave portion formed on an outer periphery of the upper main body. The second connector has a concave portion or a convex portion that is formed on an inner periphery of the lower main body and configured to fit into the convex portion or the concave portion of the first connector. When the first connector and the second connector are coupled to each other, a bottom surface of the first connector and a bottom surface of the second connector are disposed facing each other. The first connector and the second connector are coupled to provide a leakage prevention portion for preventing the liquid from leaking.
