A stretch blow-molded article comprising: a first polyester; and a second polyester having a structure different from a structure of the first polyester, wherein an intrinsic viscosity value of the first polyester is 0.60 to 0.74 dL/g, and the second polyester has a structure corresponding to terephthalic acid and a structure corresponding to bisphenol A.

A stretch blow-molded article comprising: at least one selected from the group consisting of an inorganic layered double hydroxide and zeolite: a styrene-based resin; and a wax.

A method of producing a stretch-blow-molded article, comprising: a process of producing a preform from a melt-kneaded product of a resin mixture comprising at least a wax, a styrene-based resin and a carbodiimide compound; and a process of stretch-blow molding the preform to produce the stretch-blow-molded article.

A stretch blow-molded article comprising: a polyester; a wax; and at least one selected from the group consisting of an inorganic layered double hydroxide and zeolite.

A blow molding machine for blow molding a container having an integrally formed handle; said container blow molded from a previously injection molded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.

A carrier assembly for injection molding a parison with internal threads. The carrier assembly may be used with an injection stretch blow molding machine that includes a core rod. The carrier assembly comprises a carrier insert surrounding a portion of the core rod. The carrier insert includes a thread-forming portion presenting an interior radial surface and an exterior radial surface. The interior radial surface is configured to be positioned adjacent to the core rod, and the exterior radial surface includes a threaded protrusion configured to extend away from the core rod. The carrier assembly also includes a pinion insert surrounding at least a portion of the threaded protrusion of the thread-forming portion of the carrier insert. The pinion insert is spaced apart from the thread-forming portion of the carrier insert so as to present a thread-forming cavity between the pinion insert and the carrier insert.

Machine for forming containers made of thermoplastic material by blow-molding preforms obtained by means of injection/molding within the machine, for which at least one longitudinal direction for feeding of the preforms between the stations thereof is defined, said machine including: an injection unit provided with a longitudinal injector; a station for molding the preforms, comprising a mold with a predefined number of cavities for injection/molding of preforms; a station for blowing the preforms, comprising a blowing assembly for forming finished containers; said blowing assembly comprising a smaller number of blowing cavities than the number of injection/molding cavities in the mold and being displaceable in both senses of the longitudinal direction on fixed longitudinal guides.

An apparatus for producing plastic containers includes: a forming machine for producing plastic preforms; a blow-molding machine for blowing the preforms to obtain containers, provided with a blow-molding carousel having a plurality of blow-molding molds that expand the preforms to obtain the containers; a thermal conditioning station interposed between the forming machine and the blow-molding machine; a storage station, configured for receiving and containing preforms; a supplying system for feeding the thermal conditioning station with preforms contained in the storage station.

A hollow container manufacturing method comprises; an injection molding step of forming a preform having a neck portion and a barrel portion, at least a part of the barrel portion being solid, by injection molding; an intermediate product formation step of inserting a boring rod 134 from the neck portion side into the barrel portion 23 to form a space pare of at least a predetermined depth in the barrel portion, thereby converting the preform into an intermediate molded product; and a final blow molding step of blow-molding the intermediate molded product within a final blow mold to form a hollow container which is a final molded product.

In various embodiments, a molded product delivery apparatus or a blow molding machine includes a first transfer member that includes first paired chucks that hold a portion of an outer wall of a neck portion of a molded product, and a second transfer member that includes second paired chucks that hold another portion of the outer wall of the neck portion of the molded product. From a state where the molded product is held by both of the first paired chucks and the second paired chucks simultaneously, by opening one of the first paired chucks and the second paired chucks without interfering with the other, the molded product is delivered between the first paired chucks and the second paired chucks.
