摘要： A method of feeding a composite molten resin capable of easily forming amulti-kind-multi-layer preform. An apparatus for feeding the composite molten resin has a nozzle portion which includes an outer discharge port in which an outermost annular flow path through which a main layer-forming molten resin flows, meets an outer annular flow path through which a sub-layer-forming molten resin flows inside of the outermost annular flow path; and an inner discharge port in which a shell layer-forming molten resin annularly flowing inside of the outer conflux path, meets the core layer-forming molten resin flowing inside the shell layer; the outer discharge port and the inner discharge port being arranged in this order from the downstream toward the upstream in a direction in which the molten resins flow; wherein provision is made of a shaft-like opening/closing valve for opening and closing the inner discharge port, and a gear pump for intermittently discharging the sub-layer-forming molten resin.

摘要： A preform suitable for subsequent blow-molding into a final-shaped container comprises: a neck portion; a base portion; and a body portion extending between the neck portion and the base portion; the body portion being defined between an inner surface having a circular transverse cross-sectional shape and an outer surface also having a circular transverse cross-sectional shape, the inner and outer surfaces being non-concentric, such that a wall thickness of the body portion varies circumferentially around the preform. A preform handling apparatus for retrieving a preform from a mold comprises a take-off device having a preform carrier and a take-off device alignment mechanism for maintaining the preform carrier in alignment with a contact surface of a body portion of the preform regardless of any offset between a longitudinal axis of a cylindrical outer surface of the body portion and a longitudinal axis of a cylindrical inner surface of the body portion.

摘要： The invention aims at solving problems caused by the incorporation of a gas barrier layer, that is, lowering in the dimensional accuracy of the mouth portion by thermal crystallization and delamination of the bottom, independent of the dislocation of a gas barrier layer occurring in the coinjection of a PET resin layer and the gas barrier layer. A biaxially oriented blow-molded bottle in which a gas barrier layer (3) is incorporated in a PET resin layer (2) by lamination and which is provided with a functional section (5) consisting of a screw (8) formed in the upper part of a mouth portion (4) and a stop ring (6) formed under the screw (8) and a neck ring (7) formed in the lowest part of the mouth portion (4) and a perform thereof, wherein the leading edge (3a) of the gas barrier layer (3) is set in the mouth portion (4) in such a way that the top of the leading edge (3a) does not reach the central part of the stop ring (6) constituting the functional section (5) to thereby enable the thermal crystallization of the mouth portion (4) without the influence of shrinkage and deformation due to the presence of the gas barrier layer (3) in the functional section (5) of the mouth portion (4).

摘要： A blow molded container (22) is blow molded with improved gripping areas. The gripping areas of the container contain a layer (20 (a), 20 (b) ) of an elastomer which has a greater coefficient of friction than the coefficient of friction of the container surface. The elastomer preferably is selectively on the gripping areas for that container with the surface of the remainder of the container being that of the container as formed. The container is formed from a preform (10) that has an elastomer layer (20 (a), 20 (b) ) of a size and shape to produce the elastomer on the gripping area of the container, providing a blow mold with a negative of the container and gripping area on the inner surface of the mold, orienting the preform in the mold such that the elastomer layer on the preform is adjacent to the negative of the gripping area on the inner surface of the mold, and injecting a gas into the preform to blow mold the container with the gripping areas overmolded with a layer of the elastomer.

摘要： A preform (1) having an inverted truncated conical bottom section is used. The inclined inner surface of a bottle bottom surface-forming portion (13b) of the bottom section is formed into a gently curved convex surface that extends from the lower portion of a bottle bottom edge-forming portion (13c) of the bottom section to a curved portion (13d) in the lower portion of the bottom section so that the thickness (t 3 ) of the bottle bottom surface-forming portion (13b) is greater than the thickness (t 1 ) of the barrel section (11) of the preform (1) and the thickness (t 4 ) of the bottle bottom edge-forming portion (13c). The increase in thickness of the bottom section improves the efficiency of stretching the bottom section, and the circumferential wall of the bottom section can thereby be efficiently stretched. This allows a reduction in weight (thickness) of the bottom surface section of a stretch blow molded bottle, and a reduction in weight of the bottle is thereby achieved.
