Definitions

  • the present invention relates in general to two compartment containers and in particular to a two-compartment container, each compartment holding a separate component to be mixed with one another by the end user prior to use.
  • a variety of formulations for human use such as various nutritive formulas, including baby formula, dietetic powders and a variety of drugs, are known to have a limited shelf life, which is the result of the active ingredient in the formula losing its activity due to accelerated oxidation and/or hydrolysis once this active ingredient is mixed with a liquid.
  • the formulation can also be more susceptible to micro-organism contamination. This disadvantage of prepared formulations creates the need to keep the ingredients separate and prepare the formulation just prior to use.
  • Containers having separate compartments for storing two components which are mixed together prior to use are known.
  • a major problem with these known designs is the seal of the internal partition, which may not completely separate the two ingredients, so that liquid leaks or liquid fumes may cross the partition and cause partial mixture a long time before use.
  • a two-compartment container for separately storing two components, mixing the components and dispensing a formulation formed by mixing the two components
  • the container including (a) a housing having an opening at each of its top and bottom ends and a sealing wall located between the top and bottom ends which divides the housing into two separate compartments; (b) at least one connecting member extending between the sealing wall and an inner wall of the housing defining at least one opening for flow communication between the connecting member and the housing; (c) a substantially hollow displaceable member having a sealable sleeve, the displaceable member being disposed in the housing; (d) wherein the displaceable member is axially displaceable between a first position where the sealing sleeve sealingly engages the sealing wall forming a seal which divides the housing and the displaceable member into two separate fluid-tight compartments, and a second position where the sleeve and the sealing wall are disengaged, providing flow communication between the compartments.
  • the displaceable member further includes a frangible seal for sealing a component inside a compartment defined by the displaceable member, the frangible seal being coupled to the sealing wall for breaking by the sealing wall during displacement of the displaceable member.
  • a wall of the displaceable member includes a chamfered edge serving as cutting blade for cutting a portion of the sealing wall.
  • a two-compartment container for separately storing two components, mixing the components and dispensing a formulation formed by mixing the two components
  • the container including: (a) a housing having an opening at each of its top and bottom ends and a U-shaped extension extending inwardly from a wall of the housing; wherein an innermost wall of the U-shaped extension is chamfered to define a cutting blade; (b) a substantially hollow displaceable member having a sealing wall at its bottom end which divides the container into two separate compartments, the displaceable member being disposed in the housing; (c) wherein the displaceable member is axially displaceable between a first position where the sealing wall sealingly engages the housing forming a seal which divides the housing and the displaceable member into two separate fluid-tight compartments, and a second position where the cutting blade cuts the sealing wall, thereby providing flow communication between the compartments.
  • a two-compartment container for separately storing two components, mixing the components and dispensing a formulation formed by mixing the two components
  • the container including: (a) a housing having an opening at each of its top and bottom ends and an annular flange dividing the housing into two compartments; (b) a displaceable member disposed in the housing, the displaceable member including a shaft supporting a disk-like sealing wall having an upstanding flange complementary to and adapted to sealingly engage flange in housing; (c) wherein the displaceable member is axially displaceable between a first position where the sealing wall flange seals against the flange of the housing forming a seal which divides the housing and the displaceable member into two separate fluid-tight compartments, and a second position where the shaft of the displaceable member is pushed into the housing, causing disengagement of the sealing wall flange and the housing flange, thereby permitting flow communication between the two compartments.
