RESIN CONTAINER MANUFACTURING DEVICE
The apparatus for manufacturing a resin container includes a heating unit configured to heat a preform using heaters and, a blow molding unit configured to blow-mold the preform that has been heated, accumulators that are connected to the blow molding unit and for storing a pressurized gas to be used for blow molding, and a connection pipe that connects the heating unit and the accumulators via an electrically driven valve, in which the electrically driven valve is closed when electric power is supplied, and is opened when electric power is not supplied to cause the gas in the accumulators to flow to the heating unit.

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.
CONTAINERS FORMED OF POLYOLEFIN RESIN
A preform configured to form a container when the preform is seated in a cavity of a mold and the preform is expanded within the cavity of the mold by introducing an incompressible fluid under a blow pressure into the preform to stretch the preform to assume a shape of the surrounding cavity. The preform includes a high-density polyethylene (HDPE) resin having: a melt flow index of between 0.3 and 10.0 grams per 10 minutes at a temperature of 190° C. under 2.16 kilograms of load through a test fixture of ASTM D1238; a polydispersity index of 4-24; and a density of between 0.943 and 0.965 grams per cubic centimeter.
POLYOLEFIN RESINS FOR CONTAINERS
A high-density polyethylene (HDPE) resin configured to be molded into a preform that can be biaxially expanded within a cavity of a container mold by introducing an incompressible fluid under pressure into the preform to stretch the preform to assume a shape of a surrounding mold cavity of the container mold. The HDPE resin has: a melt flow index of between 0.3 and 10.0 grams per 10 minutes at a temperature of 190° C. under 2.16 kilograms of load; a polydispersity index of 4-24; and a density of 0.943-0.965 grams per cubic centimeter.
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.
Method of delivering a liquid volume and associated apparatus
An apparatus and method of delivering a predetermined volume of a liquid product, defined as the liquid end product, formed by addition of a first and second liquid product, into a thermoplastic container formed from a heated preform positioned in a mold and having an opening opposite an injection head. Prior to injecting the second liquid product into the preform causing expansion of the container, the preform is at least partially, filled with the first liquid product.
Injection nozzle with finish cooling and counter pressure
An injection nozzle for cooling and providing counter pressure to a neck of a preform during a forming of a container from the preform. The injection nozzle includes a manifold that defines a receiving space into which the neck of the preform is received. A cavity is also defined in a part by an inner wall and an outer wall of the manifold and a plurality of ports are provided through the inner wall to communicate the cavity with the receiving space. When a cooling medium is received into the cavity, the cooling medium is directed through at least some of the ports toward the neck of the preform located within the receiving space.

The HDPE resin has: a melt flow index of between 0.3 and 10.0 grams per 10 minutes at a temperature of 190? C. under 2.16 kilograms of load; a polydispersity index of 4-24; and a density of 0.943-0.965 grams per cubic centimeter.
Method and apparatus for packaging a liquid food product
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.
