A tubular container is molded with a cap by defining; at least one portion of a cavity for molding a neck portion between a female die for receiving a cap having a screw on the inside thereof and a male die having a fixed guide rod for insertion into the cap centrally thereof. A top end portion of a preformed container body is partly inserted into the cavity. A synthetic resin, which possesses compatibility with the container body and is not fused together with the cap, is injected into the cavity to form the neck portion integrally with the container body.
