A molding system (10) for hydraulic blow molding of a container from a preform (18). The molding includes a pressurization unit (38) that is configured to receive liquid molding medium from a source; a fill head unit (12) coupled to the pressurization unit (38) to receive the liquid molding medium therefrom; a mold assembly (14) defining a mold cavity (22) in the shape of the container. During forming of the container, a nozzle piston is moved from a retracted position to an extending position where the nozzle piston (42) is engaged to inject the molding medium into the preform, thereby forming and filling the container. The fill head unit (12) defines a receiving chamber (48) for the liquid molding medium that maintains a constant volume during movement of the nozzle piston between the retracted and extended positions.
A method of forming a container (14) from a plastic preform (12) while using a liquid as a blow medium. The method is characterized by the opening of a recirculation valve (90) in communication with the liquid when the liquid is at a residual pressure. The opening of the recirculation valve (90) allowing air dispersed within the liquid to rise to the top of the container (14) before disengaging of a forming head (34) from the container (14). As a result, splashing and spillage of liquid from the neck (18) of the container (14) is eliminated when the forming head (34) disengages from the container (14).
A method of forming a container (14) from a plastic preform (12) while using a liquid as a blow medium. During the method, liquid is withdrawn from the container (14) to reduce pressure within the container (14) prior to disengaging of the injection head (34) from the container (14). In one aspect the method involves the opening of a recirculation valve (90) to reduce the pressure. The opening of the recirculation valve (90) allowing air dispersed within the liquid to rise to the top of the container (14) before disengaging of a forming head (34) from the container (14). As a result, splashing and spillage of liquid from the neck (18) of the container (14) is eliminated when the forming head (34) disengages from the container (14).
A one-step hydraulic blow molding system and method for forming a preform and a liquid filled container from the preform. The machine and method include a sealing mechanism that forms a seal primarily utilizing compressive forces in an axial direction to prevent the leakage of liquid blow medium. The sealing mechanism includes an axial end face of a forming head and an upper axial surface of a neck ring.
A method of analyzing preforms for potential bursting during forming and filling by injecting an incompressible liquid to shape the successive heating preforms into containers and fill the containers. The method defines at least one stress parameter correlated to the internal stress of the thermoplastic material of the preform and defines a range of acceptable values for the stress parameter. The method includes analyzing each successive initial preform and each successive heated preform, determining a value of the stress parameter, comparing the determined value to a range of acceptable values, and emitting an output signal when the determined value is outside the acceptable range of values.
A hydraulic blow molding system (1) for forming a container from a preform (19) by injecting a liquid product into the preform (19) thereby expanding the preform (19) into the shape of the container.

In a further aspect, the seal pin (16) is a portion of an integrated seal pin/stretch rod (16).
A hydraulic blow molding apparatus having a container forming station (32) with a forming head (42) coupled to a source (54) of liquid blow medium. The container forming station further includes a mold (34) configured to receive a preform (18) and has interior surfaces (48) that define the container shape. The container forming station (32) injects a liquid end product into the preform (18) and expands the preform (18) to simultaneously form and fill a container (28) with the liquid end product. Prior to the container (28) being removed from the container forming station (32) and while it is still full of the liquid end product, a seal (76, 176) is engaged with the container (28).
An apparatus for forming a thermoplastic container from a cylindrical preform and for delivering a predetermined volume of a beverage component into the container. The apparatus includes: a mold defining a shape of the container; a member configured to inject at least one beverage component into a recess in the preform so as to promote expansion of the preform inside the mold into the shape of the container, the member being further configured to inject the at least one beverage component in a first volume intentionally greater than the predetermined volume; and the member also being configured to remove a fraction of the first volume of the beverage component until a second volume of beverage component remaining in the container is equal to the predetermined volume.
