Abstract

PURPOSE:To improve the sealability by injection molding semi-molded forms of a cover, a body by hollow article injection molding, opening molds, then sliding the stationary mold to a position where both the semi-molded forms of a cavity are superposed, interposing a two-layer filter, closing the molds, and secondarily forming to form it in a headband-like state to be integrated. CONSTITUTION:A cover 1 and a body 2 are molded as semi-molded forms in molds in an injection molding step. The one mold is a stationary mold X, the other mold is a movable mold Y, and the molds are opened with the cover 1 and the body 2 retained in its cavity. Then, the mold X is moved to a position where the semi-molded forms of the cavity are superposed by a die slide hydraulic mechanism Z provided at the mold X side. The molds are closed while interposing a two-layer filter 3 at the cover 1 or the body 2. Then, a headband- like state is formed at the periphery of the hollow molded form to integrate the cover 1 with the body 2.
