Method of delivering a liquid volume and associated apparatus

An apparatus for forming a container from a preform and delivering a predetermined volume of a liquid end product, formed by the addition of first and second liquid products, into the container. The apparatus includes a heating oven to heat the preform, a mold defining a cavity in the shape of the container, a stretch member coupled to an actuator to stretch the preform in the mold, an injection head configured to inject the second liquid product through the mouth of the preform so as to cause expansion of the preform within the mold thereby obtaining the container, and a preform filler to at least partially fill the preform with the first liquid prior to injecting of the second liquid product and before expanding of the preform into the container.

In a method of forming a container from a thermoplastic material, a thermoplastic preform may be introduced into a blow cavity at a temperature greater than or equal to a glass transition temperature of a thermoplastic material and less than a melting temperature of the thermoplastic material. A fluid pressure may be introduced into a preform that may expand the preform radially outwardly to form a semi-finished container. An external surface of the semi-finished container may be engaged with a wall of the blow cavity. The wall of the blow cavity may be rapidly heated. Heat may be transferred to the external surface of the semi-finished container. A surface finish may be imparted from the wall of the blow cavity onto the external surface of the semi-finished container.

To simply sterilize a blow-molding machine. A mist or gas of hydrogen peroxide or a mixture thereof is introduced through a valve block disposed adjacent to a molding die, thereby sterilizing at least the molding die and an extension rod that extends into the molding die through the valve block.

Blow molding apparatus

A blow molding apparatus comprises: a continuous transport section provided with a loop-shaped transport path for continuously transporting a preform; an intermittent transport section for intermittently transporting the preform to a blow molding section; and a delivery section for holding the preform being transported on the transport path, and delivering it to the intermittent transport section. The delivery section is equipped with a cooling means for jetting a cooling fluid from a first nozzle member onto an outer surface of the preform to cool the preform locally.

Method and system for forming a self-sealing volume using a breather system

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.
