The present application includes an injection molding step and a stretch blow molding step. The stretch blow molding step is configured to include: a first step in which preliminary blow air is introduced into a preform to stretch the preform in a state in which a stretching rod does not contact the bottom of the preform; a second step which is executed after the first step, and in which the preliminary blow air is introduced into the preform and the stretching rod is moved at a set speed and pressed against the bottom of the preform to stretch the preform; and a third step which is executed after the second step, and in which final blow air is introduced into the preform to stretch the preform.

A synthetic resin preform has a cylindrical mouth portion provided with a male thread on an outer peripheral surface, a cylindrical body portion continuous with the mouth portion and a bottom portion configured to close a lower end of the body portion, the preform being formed into a container of a predetermined shape by blow molding, the synthetic resin preform further including, between the mouth portion and the body portion, a holding surface continuous with the outer peripheral surface of the mouth portion and extending radially inward relative to the outer peripheral surface. Also, a container contains contents having a container filled with contents and configured to close the mouth portion with a cap, the container being formed by blow molding the preform.

This invention provides a plastic container characterized in that an expanded layer comprising expanded cells having a flat shape with an average major axis of not more than 400 m and an average aspect ratio (L/t) of not less than 6 as viewed in cross section of the container wall along the maximum stretch direction, which are oriented in the stretch direction and are distributed so as to be superimposed on top of each other in the thickness-wise direction, is formed within the container wall. In this container, expanded cells having a flat shape are distributed so as to orient in a given direction and, thus, has light shielding properties and has a pearl-like appearance, that is, has a very high commercial value. Further, since any colorant is not contained, the suitability for recycling is excellent.

A syringe for use in pressurized injection of a fluid is provided herein. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by compression molding of an inner diameter of the barrel with a core member. In certain configurations of the syringe barrel, the stretch blow molding is provided through a nozzle of the syringe. Similarly, according to a further embodiment, a syringe for use in pressurized injection of a fluid is provided. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by shrinking an inner diameter of the syringe barrel about a core member.

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

A blow moulding machine for blow moulding a container having an integrally formed handle; said container blow moulded from a previously injection moulded 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 plastic intermediate article including a container portion and a trim portion. The container portion includes a neck portion having a plurality of threads. In embodiments, each of the plurality of threads include a first portion and a second portion, wherein the first portion is provided at a first angle relative to a centerline of the plastic blow molded intermediate article, the second portion is provided at a second angle relative to the centerline of the plastic blow molded intermediate article, and the first angle and second angle are different. A method for making a plastic container includes providing a plastic preform, blow molding the preform into an intermediate article that includes a neck portion with a plurality of blown threads, and removing an upper portion of the intermediate article.
