Substantially Concentric Compartments Patents (Class 220/506)
  • Patent number: 6053401
    Abstract: A container is disclosed, including an outer shell with an integral handle and two flexible bags within the outer shell. The outer shell has a top, a bottom and sidewalls. The outer shell also defines two openings on opposing walls. Each of the bags within the outer shell defines an aperture sealed to and surrounded by a mouth, which defines a fluid passageway from the interior of the corresponding mouth to the outside of the container. The mouth is sized and shaped such that fluid can be poured through the mouth from a source having an outlet spaced above the mouth. The handle extends outwardly from the top of the outer shell and has sufficient strength to provide essentially all support for the container when the bags are filled with liquid in either of two positions: in the first position, one of the openings is facing upwards; in the second position, each of the openings is facing sideward.

  • Patent number: 6036046
    Abstract: A container for fluids comprises an outer casing of flexible, pressure resistant material, a gas tight inner casing of flexible material lying inside of the outer casing and being separated therefrom, and a filling connection for filling the inner casing. As a result, the container is collapsible so that filling the container may take place from the collapsed condition and filling is therefore possible without pressure difference while the fluid does not enter an empty space. The egress of gas from the fluid is substantially reduced.

  • Patent number: 5607076
    Abstract: The instant invention is a beverage container having a primary purpose of lowering the temperature of a beverage directly before consumption. The device is used in combination with a conventional beverage cup defined by an outer sleeve which operates in association with the beverage cup to form a passageway for the convection of heat to lower the temperature of beverage passing through the passageway. In operation the beverage cup is placed in an inverted sealed position thereby maintaining the beverage in a hot or cold serving temperature for a longer period of time. The passageway further prevents spills and lessens the possibility of skin burning by limiting the amount of beverage that can be spilled as well as providing a radiant cooling affect for lowering of beverage temperature. A lid is further provided for concealing the beverage cup and sleeve formed passageway providing a free air space for uninhibited beverage consumption.
