  • Publication number: 20160287800
    Abstract: In a conventional laminated gasket production method, when a product of a laminated gasket is demolded from a mold, the product is rubbed against the mold and, therefore, minute scratches are formed on a surface of the laminated gasket. These minute scratches are liable to prevent reliable sealing of a liquid drug. The present invention is a method for producing a gasket to be used for a medical syringe and is characterized by including the steps of: preparing a gasket molding mold; molding a gasket having a circumferential surface portion in the mold with the gasket being laminated with a lamination film; and demolding the gasket from the mold, and then forming a groove only in the lamination film circumferentially of the circumferential surface portion of the gasket.
