Definitions

  • This invention relates generally to a package for use in the marketing of various types of fluids wherein the fluid is contained in a container forming part of the package and the fluid is dispensed from the container without exposing the fluid in the container to the atmosphere and is more particularly directed to containers of this nature wherein the fluid contained in the container is a carbonated beverage, such as beer, soft drinks and sparkling wines and the package is disposable.
  • a carbonated beverage such as beer, soft drinks and sparkling wines
  • the equivalent internal pressures generated in the container with these carbonation levels can reach 55 psig at room temperature and 110 psig at 110°F. While some success has been obtained, even the use of excess carbonation levels does not prevent product quality degradation if the product is not consumed within a relatively short time after initial opening. In addition, the decay in product quality becomes more apparent as the container approaches empty. The characteristics associated with beer would not permit beer to be marketed under such packaging techniques.
  • the entire package must be as light as possible and provided with suitable means to facilitate transportation and placement at desired locations.
  • This invention provides a disposable package for marketing fluids in containers, preferably a bottle designed to be capable of withstanding the internal pressures necessary to ensure the dispensation of the fluid from the container and having dispensing means so that the fluid may be fully or partially dispensed from the container without exposing the fluid in the container to any deleterious conditions as those discussed above in association with conventional packaging techniques.
  • the disposable package includes means for supporting the disposable package at a relatively fixed location and in a position so that the dispensing means associated therewith is readily accessible so that fluid may be dispensed therefrom.
  • the fluid may be dispensed from the container with the package in any position
  • the preferred embodiment of the invention is provided with means so that the package may be positioned on a horizontal surface, such as a table top or refrigerator shelf, while the fluid is being dispensed therefrom.
  • the fluid is a carbonated beverage and in particular the fluid is beer.
  • the disposable package comprises a hollow integrally molded plastic container having the desired capacity and having a hemispherical bottom portion, an annular central portion and a hemispherical top portion with an opening of a desired size in the top portion.
  • the dispensing means for the container is secured in the opening in the top portion.
  • the disposable package includes support, protective and decorative means which are secured to the container and are comprised of two separate integrally molded plastic members each of which is secured to the container by suitable means. One of the members surrounds the top portion of the container and means are provided on the top portion of the container and the one member so as to prevent relative linear movement between the top portion of the container and the one member.
  • the other member surrounds the bottom portion and may be secured thereto by suitable means such as an adhesive.
  • the one and the other members are each provided with means forming aligned planar surfaces so that the dispensable package may be supported in a relative fixed position at any desired location lying generally in one plane, such as a table top or refrigerator shelf.
  • the other member is also provided with a generally planar surface for supporting the disposable package on a plane perpendicular to the one plane.
  • a handle is secured to the top portion of the one member to facilitate the carrying of the disposable package.
  • the one and the other members are shaped so that when the disposable package is being supported solely by the support means on the other member, one disposable package may be stacked on another disposable package with a portion of the one member nested in a portion of the other member for shipping and storage.
  • the dispensing means includes a nozzle through which the fluid is dispensed; a passageway leading to the nozzle; means for opening and closing the passageway leading to the nozzle; a flow modulator for locking the dispensing means in an inoperative position during shipment, for placing the dispensing means in condition so that fluid may be dispensed from the container and for limiting the movement of the means for opening the passageway leading to the nozzle; a flow restrictor for reducing the pressure on the fluid as it flows therethrough; and means for ensuring that there is no passageway between the fluid in the container and the means for opening and closing the passageway leading to the nozzle until it is desired to use the dispensing means for the first time to dispense fluid from the container.
  • the means for opening and closing the passageway leading to the nozzle is maintained and locked in ⁇ -closed position during shipment and commercial storage, there is in effect a double seal until it is desired to use the dispensing means for the first time to dispense fluid from the container.
  • Means are provided to maintain the pressures within the container within a desired range of pressures throughout the shelf life and dispensing cycle until the fluid is completely dispensed from the container and to ensure that substantially all of the fluid is dispensed from the container.
  • It is an additional object of this invention to provide dispensing means for dispensing fluid from a container including means for opening and closing a passageway leading to a nozzle through which the fluid is dispensed from the container which means are maintained and locked in a closed position during shipment and commercial storage and means for ensuring that there is no passageway between the fluid in the container and the means for opening and closing the passageway leading to the nozzle during shipment and commercial storage so that there is in effect a double seal until it is desired to use the dispensing means for the first time to dispense fluid from the container.

  • the container 10 is rinsed and a pressure pouch 30 is activated and placed in the container 10.
  • the container 10 is then placed in an upright position and filled with a desired amount of fluid, which in the preferred embodiment is beer.
  • a dispenser means such as that illustrated in Fig.
  • the dispenser handle 270 is in a closed position with the flow modulator 294 in place to prevent accidental opening of the dispenser handle 270.
  • the flow restrictor 258 is in the location illustrated in Fi g. 13.
  • the container 10 is then moved into the protective and support member 32 until the projection 54 has moved over the tapered surface 52 and into its final assembled position with the surfaces 90 and 92 in contacting relationship'and the surfaces 82 and 88 in contacting relationship so as to prevent relative linear movement between the container 10 and the protective and support member 32, as described above.
  • the close fit of the surfaces 90 and 92 and 82 and 88 provides sufficient frictional forces to prevent relative rotational movement between the container 10 and the protective support member 32.
  • the pressure in the container be kept substantially constant and equal to or somewhat greater than the natural carbonation pressure of the beer. This is particularly important during the dispensing of the beverage from the container in order to minimize foaming.
  • the nature of the design is such that the pressure that remains in the container when all the fluid has been evacuated therefrom is approximately the same as the pressure when full. This enables the use of lower pressures that are close to the natural carbonation pressures of the beverages in the container.
  • the disposable package of this invention is preferably for use in the marketing of relatively large quantities of fluids such as four or more liters of a beverage and is particularly suited for use in marketing beer in one container containing the equivalent of twenty-four twelve fluid ounce containers.
