  • Publication number: 20040222224
    Abstract: The invention includes aseptic packages and methods and systems allowing aseptic filling on a conventional filling line, with relatively small and inexpensive equipment modifications. The invention allows avoidance of the conventional need to encase all or part of the filling equipment in a sterile air atmosphere. The invention includes a package, fitted with a flexible membrane, which can trap and carry its own sterility through the filling steps, whereby the membrane finally becomes part of the cap of the package. The invention reduces product risk, operator specialisation and the costs of aseptic filling.

  • Publication number: 20030233980
    Abstract: Methods and systems are provided for making a coated plastic container, such as for packaged beverages, possessing a gas barrier and having enhanced resistance to loss in barrier due to handling abuses expansion of walls of the container. The system comprises a vacuum cell, a coating source in the vacuum cell for supplying a coating vapor to an external surface of a plastic container positioned within the vacuum cell, and gas feeds for supplying one or more process gases into an interior space of the vacuum cell. The coating source heats and evaporates an inorganic coating material, such as metal or silicon, to form a coating vapor, which is energized to form a plasma. The process gases include a carbon-containing gas, such as acetylene.

  • Patent number: 6610210
    Abstract: A disposable cartridge device is provided for use in a heated cartridge water treatment system in which particles, formed by the heat-induced reaction of bicarbonates in the water, can be efficiently collected in non-turbulent particle settling zones. The cartridge includes multiple containers which are assembled to fit into each other and which form channels for the flow of water within gaps between the walls of the containers. When the particle collecting section becomes full, the water flow automatically is blocked, or cut-off, which signals the need to replace the cartridge. The cartridge also can include a polishing filter and a heater mounted to a surface of the outer container.

  • Patent number: 6599569
    Abstract: A coated plastic container provides for low permeability to gases and vapors. A method and system for coating plastic containers includes applying a thin inorganic oxide layer to the external surface of the containers with plasma-assisted vacuum vapor deposition. For example, the coating can include silica which is bonded to the external surface of the container. This coating is flexible and can be applied regardless of the container's internal pressure or lack thereof. The coating firmly adheres to the container and possess an enhanced gas barrier effect after pressurization even when the coating is scratched, fractured, flexed and/or stretched. Moreover, this gas barrier enhancement will be substantially unaffected by filling of the container. A method of recycling coated plastic containers and a method and system for packaging a beverage using the coated containers are also disclosed.

  • Publication number: 20030077400
    Abstract: A method, composition and system for coating an external surface of containers and in particular, plastic containers, provides for low permeability to gases and vapors. The coating applied to the external surface of the containers is very thin and is comprised of one or several inorganic substances or layers of substances. For example, the coating can include silica which is bonded to the external surface of the container. This coating will be flexible and can be applied regardless of the container's internal pressure or lack thereof. The coating will firmly adhere to the container and possess an enhanced gas barrier effect after pressurization even when the coating is scratched, fractured, flexed and/or stretched. Moreover, this gas barrier enhancement will be substantially unaffected by filling of the container.

  • Publication number: 20030007786
    Abstract: Apparatuses and methods for use in vacuum vapor deposition coating provide for simpler, economical and continuous operation. A system and method for continuously melting and evaporating a solid material for forming a coating vapor includes the use of a separate melting crucible and evaporating crucible. A system and method for energizing the evaporative solids to form a plasma which includes first and second electrodes and a device for selectively switching polarity between the first and second electrodes to avoid coating vapor deposition on the electrodes. Another a system and method for energizing the evaporative solids to form a plasma which includes an electric arc discharge apparatus with a cathodic and an anodic part. A continuously fed electrode is disclosed for continuous vaporization of electrode members in an electric arc discharge. An apparatus and method provides for measurement of the rate of evaporation from an evaporator and the degree of ionization in a vapor deposition coating system.

  • Patent number: 6451211
    Abstract: A water treatment method uses a removable, disposable cartridge having an internal mesh structure. A permanent heater heats water fed to the cartridge. Precipitated solids collect on the mesh surface provided temperature and residence time are appropriately maintained. The heat breaks down the bicarbonate hardness of the water thereby depositing carbonates on the mesh surface and heavy metals will be codeposited due to the resultant change in pH. The cartridge has a head-space for collecting entrained gasses such as volatile organic compounds, chlorine and air. Water sterility is achieved by heating the water over an appropriate period of time. Turbidity is removed within the cartridge due to settling induced by the low fluid velocity controlled by a controller and by a filter provided at the outlet of the cartridge. The filter will become blocked when bicarbonate hardness is carried over forcing a user to replace a spent cartridge.

  • Patent number: 6444155
    Abstract: A very thin inner layer composed of a polymer chosen for its barrier and/or inertness properties is fabricated within a container preform constructed mainly from another polymer, or a structure of polymers. The inner layer on the preform is produced either by a controlled coating method involving coating of the injection mold core rod prior to injection molding or by a coating applied directly to the preform after injection molding. This enables both inner and main layers to be brought together at a time when the interface between them is molten. A tie layer can be employed, when desirable, to enable the layers to be combined without melting the layer interface.

  • Publication number: 20010042510
    Abstract: Plasma assisted polymerization and deposition of a very thin inner surface coating in a plastic or metal container without an undesirable increase in container surface temperature is provided to change the surface properties of the internal plastic surface of a container by reaction of the surface with a reactive gas which has been energized to produce a plasma or the surface is activated by a plasma of reactive gas so that it becomes receptive to a further surface reaction.
