Title: Method for removing thin film
Inventor: HIRAI MASAAKI
IPC: B05D3/12
Filed: 1990-08-24
Abstract: PURPOSE:To easily remove a thin film while preventing the occurrence of damage to a work by spraying a mixture of fluid and abrasive material onto a thin film on the surface of a work at the prescribed angle or less. CONSTITUTION:A thin film 7 of SiO2, Si3N4, etc., adhering to the surface of a work 1, such as glass substrate, is removed by using an abrasive material. At this time, the angle formed by the surface of the work 1 and the spray direction of the abrasive material 3 sprayed from a spray gun 2 is set at <90 deg., preferably <60 deg.. As a result, the abrasive material 3 is accelerated by pressed air and allowed to collide with the thin film 7 on the work 1 surface. At this time, among the kinetic energy of the abrasive material 3, the components in the direction perpendicular to the work 1 surface break the thin film 7, and, on the other hand, the components in the parallel direction remove the thin film 7 by peeling. By this method, the thin film can be removed under the optimum conditions while obviating the necessity of the spraying of the abrasive material at excessive speed.

Abstract: PURPOSE:To easily obtain a lightweight bottle with the thin-walled bottom part by a method wherein the bottom part of a bottomed parison is formed into a spherical shape in such a manner that the curvature radius at the inner side of the bottom part is made smaller than that at its outer side and the wall thickness at the central part of the bottom part is made thinner. CONSTITUTION:A bottomed parison 3 is formed by injection-molding thermoplastic resin in an injection mold 1 so as to form the bottom part of the bottomed parison 3 into a spherical shape in such a manner that the curvature radius R1 at the inner side of the bottom part is made smaller than the curvature radius R3 at its outer side and the wall thickness at its central part is made thinner. The curvature radius R2 at the port of transition from the tip to the cylinder is made smaller than R3 and at the same time larger than R1 so as to make the transition from the curved part to the straight part smoother. At the same time, when the runner part solidifies itself so as to be able to remove from a mold, the solidified part of the injection-molded bottomed parison is only the central part 31 of the bottom part. The part 32, which is a little apart from the central part keeps on being thermoplastic or easily restores to be thermoplastic by controlling temperature. Accordingly, the remaining part excluding the central part 31 of the bottom part are fully stretched by blow molding so as to obtain a bottle the wall thickness at the bottom part of which is thin is obtained.
