Definitions

  • the present invention relates generally to containers for storing and dispensing substances. More particularly, the invention relates to containers comprising container bodies and container closures that are penetrable by a filling member for filling the sealed container bodies with substances, such as beverage whiteners, and are thermally resealable for resealing the penetrated region of the container closures, and over closures that are engageable with the container closures and removable relative to the container bodies to remove the container closures from their respective container bodies.
  • FIGS IA and IB illustrate a container typically produced by prior art systems.
  • the containers are created by vacuum-sucking preformed rolls of stock into the desired shape, which are then pre-sterilized by flushing the interior and exterior surfaces of the open containers with a fluid sterilant, such as peroxide vapor or vaporized hydrogen peroxide ("VHP"), to sterilize the food contacting surfaces.
  • VHP peroxide vapor or vaporized hydrogen peroxide
  • the containers are flushed with heated sterile air in order to re -vaporize any fluid sterilant that condenses on the container surfaces and to flush away the sterilant.
  • the containers are filled through their respective open mouths with the desired product and, after filling, the containers are capped with a peel-back paper or foil cover to seal the product within the containers.
  • the sterilizing, flushing, filling and capping processes are all performed within the same sterile zone of the filling system.
  • Another drawback is that filling the containers with a number of separate liquids, for example, to create containers holding liquids of varying flavors, can be cumbersome and prohibitively expensive, as many manufacturing assembly lines are currently designed to fill containers with one liquid at a time and, therefore, in order to fill containers with multiple liquids, such systems must be shut down, completely flushed out, cleaned, connected to a new liquid source and then started up again. Alternatively, multiple assembly lines may need to be built and set up for each desired liquid or flavoring, which would add to the overall manufacturing expense and complicate the filing and sterilization process.
  • the present invention is directed to a container comprising a container body defining a storage chamber therein for receiving a substance, a first aperture in fluid communication with the storage chamber, and a container closure for sealing the storage chamber.
  • the container closure includes a container closure base defining a second aperture in fluid communication with the storage chamber, a closure stopper that overlies the second aperture and is penetrable by a filling member for aseptic filling through a filling member aperture formed therein, and a sealing portion engageable with the container body prior to aseptically filling the storage chamber with the substance.
  • the sealing portion preferably forms a substantially dry hermetic seal between the container closure and container body.
  • the container also includes an over closure engageable with the container closure, preferably after filling the container and thermally or otherwise sealing the filling member aperture.
  • the over closure is removable relative to the container body to substantially simultaneously remove the container closure from the first aperture and allow the substance to be dispensed from the container.
  • the container closure base defines a plurality of apertures angularly spaced relative to each other and extending about a periphery of the container closure base. Accordingly, the closure stopper material is allowed, during the molding process, to flow through the plurality of apertures and be received within an annular groove formed on an underside of the container closure base to, in turn, form an annular seal between the container closure and container body.
  • the over closure is pivotally secured to the container body and is movable between a first position and a second position relative to the container body.
  • the over closure removes the container closure from the container body when the over closure is moved between the first and second positions.
  • the over closure is connectable to the container body by a at least one frangible member for providing evidence of tampering and, in one such embodiment, a pull tab is connected to the frangible member for breaking the connection between the frangible member and the over closure.
  • the frangible member is mechanically interconnected with the body to releasably secure the over closure to the body.
  • the frangible member In order to open the container, the frangible member is pulled away from the body to disconnect the frangible member from the body and, in turn, allow removal of the over closure and container closure from the body.
  • the over closure is fixedly secured to the container closure and pivotally attached to the container body to remove the container closure from the first aperture and allow dispensing therethrough.
  • the storage capacity of the container is within the range of about 15 ml to about 45 ml. In other embodiments of the present invention, the storage capacity of the container is within the range of about 25 ml to about 35 ml.
  • the present invention is directed to a method comprising the following steps: providing at least one container body defining a storage chamber therein for receiving a substance, and a first aperture in fluid communication with the storage chamber; a container closure removably attached to the container body for sealing the storage chamber, including a container closure base defining a second aperture in fluid communication with the storage chamber, a closure stopper overlying the second aperture and penetrable by a filling member through a filling member aperture therein for aseptically filling the storage chamber with a substance, such as a liquid product or products, wherein the filling member aperture is thermally resealable to seal the substance within the storage chamber with respect to the ambient atmosphere, and a sealing portion engageable with the container body prior to aseptically filling the storage chamber with the substance and forming a substantially dry hermetic seal between the container closure and container body.
  • the method further includes providing at least one over closure engageable with at least one of the container closure and container body after filling and thermally resealing the filling member aperture, and removable relative to the container body, wherein removal of the over closure results in substantially simultaneous removal of the container closure from the first aperture to allow dispensing of the substance therethrough; and providing a first liquid source and a first filling member coupled in fluid communication with the first liquid source.
  • the method further includes penetrating the stopper with the first filling member through the filling member aperture; introducing a first liquid component through the first filling member and into the storage chamber; withdrawing the first filling member from the storage chamber; thermally resealing the filling member aperture to hermetically seal the filled storage chamber with respect to the ambient atmosphere; securing the over closure to the container; and at least one of (i) removing the over closure and, with it, the container closure to expose the first aperture for dispensing product therethrough, and (ii) pivotally moving the over closure between a first position and a second position relative to the container body and, in turn, removing with the over closure the container closure from the container body as the over closure is moved from the first position to the second position.
  • the method further comprises: providing at least one additional liquid source and at least one additional filling member coupled in fluid communication with the at least one additional liquid source in fluid communication with the storage chamber of the container through the first aperture, and aseptically introducing the at least one additional liquid component through the at least one additional filling member and into the storage chamber and, in turn, combining the first and the at least one additional liquid components into a liquid product formulation within the sterile chamber of the container.
  • One advantage of the present invention is that the product can be aseptically filled into sealed, empty sterile containers, thus avoiding the need to sterilize the product by retort after filling and the negative effects of retort on the filled product.
  • Another advantage of the present invention is that the stopper is sealed to the container body prior to filling the container, thereby forming a dry seal between the stopper and container body and avoiding the seal integrity problems encountered with "wet" seals in the prior art.
  • Another advantage of some embodiments of the present invention is that multiple products or product components may be aseptically filled into the same sealed, empty, sterile container at discrete time intervals, and the container and its contents remain sterile during the entirety of the process.
  • Another advantage of some embodiments of the present invention is that filling the containers with a number of separate liquids in the manner described, for example to create containers holding different flavors, is now possible in one assembly line.
  • Another advantage of the present invention is that removal of the over closure results in substantially simultaneous removal of the container closure and stopper thereby providing a convenient way of opening the container to dispense the substance without having to separately manipulate the container closure and stopper.
