A blow molding device of the invention includes a pair of blow cavity split molds (50A, 50B), a chuck member (80) that chucks a mouth portion (20) and conveys a preform (10A), a blow core mold (70) that includes a tubular portion (71) which surrounds circumferences of the mouth portion and a flange (25) and introduces blow air into the preform, and a pair of projecting members (60A, 60B) which have a halved ring shape and are provided detachably on each upper surface of the pair of blow cavity split molds. Each of the pair of projecting members includes an airtight sealing portion (61) which is in contact with a lower end face of the tubular portion of the blow core mold, and a positioning portion (62) which positions the flange of the preform.

摘要:
An injection nozzle for cooling and providing counter pressure to a neck of a preform during a forming of a container from the preform. The injection nozzle includes a manifold that defines a receiving space into which the neck of the preform is received. A cavity is also defined in a part by an inner wall and an outer wall of the manifold and a plurality of ports are provided through the inner wall to communicate the cavity with the receiving space. When a cooling medium is received into the cavity, the cooling medium is directed through at least some of the ports toward the neck of the preform located within the receiving space.

The injection device (4, 68, 101) for forming a preform (2) into a container and filling said container comprises: - a main housing (22, 73) comprising an inlet (16), an outlet (18) and an injection chamber (44), - a closing body (30), movable relative to the outlet (18) between a closed position and an opened position, - a closing diaphragm (38, 102) attached at least to the closing body (30), the injection chamber (44) being delimited at least by an inner surface (48) of said closing diaphragm (38, 102), said closing diaphragm (38, 102) having an outer surface (50) defining an outside area (46, 108), - a bearing surface against which a supported portion of the outer surface (50) of the closing diaphragm (38, 102) is applied, the closing diaphragm (38) further comprising a free portion (49, 79, 112) forming with the supported portion the whole outer surface (50) of the closing diaphragm. The bearing surface is arranged such that the surface of the free portion (49, 79, 112) decreases when the closing body (30) moves from the closed position to the opened position.
