Definitions

  • the present invention relates to a two compartment container, and more particularly, to a two compartment container for holding two fluids separate until such time as mixing is desired.
  • a two-compartment container has independent vessels or storage compartments that can hold various combinations of fluids, powders, or pastes that are stored in a separated state until the user decides to mix and utilize the products.
  • These types of containers are most useful in applications where keeping product ingredients separate until use extends shelf life or enhances product
  • the present disclosure relates to a container for storing at least two fluids comprised of a first compartment for holding a first fluid and a second compartment for holding a second fluid until such time as the user decides to mix the fluids.
  • the fluids may be liquids or gases or a combination of liquids and gases.
  • fluids include water based liquids, alcohol based liquids, oil based liquids, petroleum based ointments, viscous liquids, such as gels, oils, and ointments.
  • the first or main compartment is typically clear which allows the user to observe the mixing of the fluids, although the compartment may be translucent or even opaque. It is large enough to house the volumes of both the first and second fluids once combined. Additionally, there is typically a removable dropper or other form of dispenser, such as, for example, a pump, in communication with the first compartment for dispensing the fluid after it has been mixed.
  • a removable dropper or other form of dispenser such as, for example, a pump
  • the second compartment is typically smaller in size, although it could be of equal or larger volume than the first compartment. It is typically located at the base of the first compartment opposite the dispenser.
  • the second fluid stored in the second container is driven into the first container to mix with the first fluid by stored energy or tension.
  • tension mechanisms such as springs, valves, and a piston
  • the fluids are mixed without much effort by the user, and without causing any puncturing, tearing or removal of any membrane or stopper deployed between the two
  • valves and fluids Various tensioning, valve, and piston configurations can be employed without departing from the scope of the invention as long as the release of stored energy causes the second fluid to cause the opening of a valve or other reusable barrier interposed between the first and second compartments, thereby allowing the mixing of the two fluids. Additionally, the valve or other reusable barrier may allow the flow of fluid in only one direction, or in multiple directions depending on the forces that are applied to the first fluid and second fluid.
  • the combined fluids may be dispensed from the upper compartment. It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive.
  • the lower compartment sits on a piston that is surrounded by a compressed spring or other tensioning mechanism that is held in compression by a latch mechanism.
  • the latch mechanism Upon turning a base portion of the lower container, the latch mechanism releases the spring which forces the piston upward which in turn compresses the fluid stored in the lower compartment and forces the fluid upward.
  • a valve At the top of the lower compartment is a valve that is formed from a solid disc of
  • valve adapter has a single opening that is slightly inward of the outer edge of the valve adapter.
  • the valve adapter may also include a plurality of openings extending circumferentially to the valve adapter and slightly inward of the outer edge of the valve adapter. Other opening configurations are possible as well, without departing form the spirit of the invention.
  • the valve adapter interposes between a transition chamber located above the valve and the upper compartment of the container.
  • the valve includes a lip that sits on the top a cylindrical extension of the lower compartment.
  • a first spring or other tensioning mechanism below adjacent to or corresponding to the lower compartment, the second fluid is forced upward against the valve.
  • the valve is held in place against the top of the cylindrical extension by a slightly tensioned second spring or other tensioning mechanism.
  • the value of the spring constant of the second spring is less than the spring constant of the first spring.
  • tensioning mechanisms might be, for example, the valve itself or the valve adapter composed from compressible materials.
  • the pressure resulting from decompression of the lower spring causes the fluid from the lower compartment to force the valve upward and passes the lip of the valve to enter the transition chamber and to pass through the valve adapter into the upper compartment causing the mixing of the first and second fluids.
  • the container for mixing two stored fluids comprises a first compartment for holding a first fluid and a second compartment for holding a second fluid.
  • the container has a valve for preventing the mixing of the first and second fluid, a first tension mechanism for maintaining the valve in a normally closed position, and a piston held in position by a second tension mechanism.
  • the container also comprises a release mechanism for releasing the second tension mechanism, wherein the release of the second tension mechanism causes the piston to open the normally closed valve, allowing the second fluid to flow past the valve into the first compartment.
  • a method for preparing a two compartment container for mixing two isolated fluids comprises inserting a first fluid in a first compartment, inserting a second fluid in a second compartment, wherein the first compartment and the second compartment are coupled. Isolating, via a valve between the first compartment and second compartment, the first and second fluid, positioning a first tension mechanism to maintain the valve in a normally closed position and positioning a second tension mechanism to hold a piston in a first position. Such that upon release of the second tension mechanism the piston moves to a second position providing for the second fluid to flow past the valve into the first compartment.

  • Valve 1 1 is held in place against the top of the cylindrical extension by a slightly tensioned retaining spring 19 or other tensioning mechanism.
  • the spring constant of retaining spring 19 is less than the spring constant of release spring 20.
  • tensioning mechanisms might be, for example, the valve itself or the valve adapter composed from compressible materials.
  • the pressure resulting from decompression of the release spring 20 causes the fluid from lower compartment 14 to force valve 1 1 upward and passes the lip of valve 1 1 to enter the transition chamber and to pass through the opening in valve adapter 10 and disk 9 into upper compartment 8 causing the mixing of the first and second fluids.
  • Top cap 1 is a generally cylindrical hollow cap with a solid top portion on one end and an open portion on the opposite end. Top cap 1 engages with the neck band 5 and is held in place by ridge 703, although other methods of retention, such as screw threads, press releases or the like could be used. Top cap 1 is large enough to cover dispenser 2, thereby preventing accidental dispensing of the fluid. Although FIG. 1 depicts top cap 1 as generally cylindrical, it is to be appreciated by those skilled in the art, that top cap 1 can take on other geometries, such as, for example, oval, square, or conical.
  • FIG. 2 shows upper portion 200.
  • Dispenser bulb 2 has an outside surface 20 and an inside surface 21 , thereby creating cavity 22.
