Abstract: A preform for biaxial stretching blow molding. The preform being formed into a closed-end cylinder by direct blow molding and which is to be shaped into a container using a pressurizing liquid medium. The preform has either a single-layer or a multilayer structure constituted of one of a polyethylene resin having an MFR of 1.0-1.5 g/10 min. or a polypropylene resin having an MFR of 0.8 to 2.3 g/10 min.

Abstract: A construction that prevents liquid from dripping from a nozzle and adhering to a product when the nozzle is separated from a mouth of the product after liquid-blow molding. A preform includes a mouth, a body, and a neck support portion, and is provided with a step surface on an inner peripheral face adjacent to the neck support part. A liquid blow molding apparatus includes a nozzle that is inserted in the mouth of the preform, a pressurized liquid-supply unit that supplies pressurized liquid to the nozzle, and a sealing member that is formed in a cylinder and fits on an outer peripheral face of the nozzle abuts the step surface, in an axial direction, when the nozzle is inserted in the mouth of the preform to seal the gap between the nozzle and the inner peripheral face of the preform.

Abstract: A liquid blow molding apparatus for liquid blow molding a resin preform into a container having a prescribed shape. The apparatus includes a blow molding mold in which the preform is disposed; a blow nozzle that engages in an opening of the preform; a pressurized liquid supply that supplies a pressurized liquid to a supply path that is connected to the blow nozzle; and a seal member that is provided inside the supply path and opens and closes the supply path with respect to the blow nozzle. The pressurized liquid supply is configured to start supplying the pressurized liquid to the supply path after the seal member has begun to open.

Abstract: A preform formed from polypropylene or high density polyethylene and with which a container of a desired shape can be precisely molded by liquid blow molding. When formed of polypropylene as a closed-bottom cylinder shape having an open end section and a body section, the preform is molded into the container by stretching the body section in the axial direction by a stretch ratio of 2.25-4.34, inclusive, and in the radial direction by a stretch ratio of 1.95-5.00, inclusive. When formed of high density polyethylene as a closed-bottom cylinder shape having an open end section and a body section, the preform is molded into the container by stretching the body section in the axial direction by a stretch ratio of 1.69-2.50, inclusive, and in the radial direction by a stretch ratio of 2.26-5.07, inclusive.

Abstract: A composite container having a paper label adhered without adhesives to a container body at at least one of the top end edge outer circumferential surface of the container body and the bottom end edge outer circumferential surface of the base part of the container body. Adherence of the paper label to the container body being effectuated by disposing the paper label in a mold and biaxial stretch blow shaping a preform into the container body with a liquid as a pressurized medium.
