Abstract

PURPOSE:To inject and mold a plastic vessel, an upper end surface of the mouth section thereof is horizontal, easily by removing a projecting plug formed at an upper section of the mouth section by bringing down the plug and opening the spout. CONSTITUTION:The plastic vessel, the mouth section 30 thereof has the projecting plug 29 and a thin section 31, is injected and molded, said projecting plug 29 is contacted with a plug removing member 32 and brought down, the thin section 31 is cut and torn, the projection plug 29 is removed completely and the spout 33 is opened. The upper end surface 34 of the mouth section 30 is horizontal and smooth, and perfect airtight property is kept when engaging a cap. The mouth section need not be opened by means of a hot cutter, etc. as seen in conventional devices, and the plastic vessels can easily be mass-produced.
