Abstract
Official abstract text for this publication.
A blow molding device includes a blow molding mold to which a preform is fitted, a blow nozzle that is fitted to a mouth tubular portion of the preform, and a pressurized liquid supply unit configured to supply a pressurized liquid to the blow nozzle, the preform being to be molded into a shape conforming to a cavity of the mold by filling the liquid into the preform through the blow nozzle. The blow nozzle includes a central hole and a plurality of peripheral holes having an inner diameter smaller than an inner diameter of the central hole and arranged to surround the central hole. The liquid is filled into the preform through the central hole and the plurality of peripheral holes.
First claim
Opening claim text (preview).
1 . A blow molding device, including a blow molding mold to which a bottomed tubular preform is fitted, a blow nozzle that is fitted to a mouth tubular portion of the preform fitted to the mold, and a pressurized liquid supply unit configured to supply a pressurized liquid to the blow nozzle, the preform being to be molded into a shape conforming to a cavity of the mold by filling the liquid into the preform through the blow nozzle, wherein the blow nozzle includes a central hole arranged on an axis of the blow nozzle and a plurality of peripheral holes having an inner diameter smaller than an inner diameter of the central hole and arranged to surround the central hole, the liquid being filled into the preform through the central hole and the plurality of peripheral holes. 2 . The blow molding device of claim 1 , wherein the plurality of peripheral holes is arranged at an equal interval in a circumferential direction about the central hole. 3 . The blow molding device of claim 2 , wherein the plurality of peripheral holes is arranged in a plurality of layers located at different distances from a center of the central hole, and in each layer, the corresponding peripheral holes are arranged at an equal interval in the circumferential direction about the central hole. 4 . The blow molding device of claim 1 , wherein the blow nozzle is configured to have a length that allows a tip of the blow nozzle to align with a border area between the mouth tubular portion and a main body portion of the preform. 5 . The blow molding device of claim 1 , wherein the blow nozzle is configured to have a length that allows a tip of the blow nozzle to protrude into a main body portion of the preform. 6 . The blow molding device of claim 1 , wherein the mold includes a receiving member that is displaceable along an axis of the preform from a predetermined position in the cavity to a bottom surface of the mold. 7 . The blow molding device of claim 2 , wherein the blow nozzle is configured to have a length that allows a tip of the blow nozzle to align with a border area between the mouth tubular portion and a main body portion of the preform. 8 . The blow molding device of claim 3 , wherein the blow nozzle is configured to have a length that allows a tip of the blow nozzle to align with a border area between the mouth tubular portion and a main body portion of the preform. 9 . The blow molding device of claim 2 , wherein the blow nozzle is configured to have a length that allows a tip of the blow nozzle to protrude into a main body portion of the preform. 10 . The blow molding device of claim 3 , wherein the blow nozzle is configured to have a length that allows a tip of the blow nozzle to protrude into a main body portion of the preform. 11 . The blow molding device of claim 2 , wherein the mold includes a receiving member that is displaceable along an axis of the preform from a predetermined position in the cavity to a bottom surface of the mold. 12 . The blow molding device of claim 3 , wherein the mold includes a receiving member that is displaceable along an axis of the preform from a predetermined position in the cavity to a bottom surface of the mold. 13 . The blow molding device of claim 4 , wherein the mold includes a receiving member that is displaceable along an axis of the preform from a predetermined position in the cavity to a bottom surface of the mold. 14 . The blow molding device of claim 7 , wherein the mold includes a receiving member that is displaceable along an axis of the preform from a predetermined position in the cavity to a bottom surface of the mold. 15 . The blow molding device of claim 8 , wherein the mold includes a receiving member that is displaceable along an axis of the preform from a predetermined position in the cavity to a bottom surface of the mold. 16 . The blow molding device of claim 5 , wherein the mold includes a receiving member that is displaceable along an axis of the preform from a predetermined position in the cavity to a bottom surface of the mold. 17 . The blow molding device of claim 9 , wherein the mold includes a receiving member that is displaceable along an axis of the preform from a predetermined position in the cavity to a bottom surface of the mold. 18 . The blow molding device of claim 10 , wherein the mold includes a receiving member that is displaceable along an axis of the preform from a predetermined position in the cavity to a bottom surface of the mold.
