Abstract

PURPOSE:To manufacture the captioned bath cover which is light, strong, gorgeous and inexpensive by a method wherein the main body is a hollow plate body manufacuted by air-blowing a parison and the intended number of reinforced plates are made up of part of the parison. CONSTITUTION:The parison 27 of synthetic resin is inserted into a blow mold 21 and clamped and as the side walls of the parison are pressed partially by a sliding plate 25, a hollow plate body having reinforced plates 10, 11 is molded by air blowing, side walls 4 to four sides between the upper plate 2 and the lower one 3 are molded in a unitary body with the reinforced plates 10, 11, the geometrical moment of inertia is large in either a vertical or a lateral direction and a specially large thickness is not required to obtain a light bath cover 1.
