A plastic preform includes a hollow body portion including a closed base portion and a lower portion and a lower portion extending upwardly from the closed bottom portion; and a neck portion extending upwardly from the lower portion. The neck portion includes a dispensing opening positioned at a top of the neck portion, threads positioned below the dispensing opening, a tamper-evident formation having a lower surface and positioned directly below the threads, and a support flange having an upper surface and a lower surface and positioned below the tamper-evident formation. In an embodiment, the plastic preform is formed of a material comprising polyethylene terephthalate (PET), and a vertical distance from the lower surface of the tamper-evident formation to the lower surface of the support flange is from 0.125 to 0.150 inches. Containers and methods for molding preforms and making containers are also disclosed.

This invention relates to a container (1) which is pre-filled or pre-fillable with one or more substances, such as a medical liquid and similar, comprising a squeezable activation compartment (2) intended to contain said one or more substances, a dispensing compartment (3) including a first portion (31) equipped with at least one dispensing member (311, 312, 314) of said one or more substances, and a second portion (32), wherein said second portion (32) of said dispensing compartment (3) and said activation compartment (2) are fluid-dynamically connected, and an activator element (4) arranged inside said container (1).

This invention also relates to a method for dispensing at least one substance by means of a container (1), and to a production method of a container (1).

A container production method including a preform setup step of disposing a preform in a blow molding mold and engaging a filling nozzle with a mouth of the preform; a blow molding step of liquid blow molding the preform by supplying a pressurized liquid into the preform; a liquid discharge step of releasing the blow molding mold and pressing a trunk of the container after molding with a pressing portion that is inserted from a clearance between separated mold pieces adjacent to each other to discharge a liquid in the container to the outside of the container by a predetermined amount; and a headspace forming step of forming a headspace in the container by separating the filling nozzle from a mouth of the container.

A method for the production of blow-molded containers that are sterile at least in certain regions, and a blow-molding machine configured to carry out the method. In accordance with the method, blowing stations are arranged on a rotating blowing wheel. A preform of a thermoplastic material is first heated and then stretched in a blowing station by a stretching rod and subjected to a pressurized blowing fluid via a blowing nozzle. A sterilizing fluid is supplied to the preform in the blowing station to perform a sterilization. The sterilizing fluid is fed into the preform from an outlet and is carried away again via an inlet and in between follows a flow path. The sterilizing fluid is made to pass through or pass by the stretching rod on its flow path, and the sterilizing fluid is supplied while the blow-molding machine continues to operate.
