Description
TWO COMPARTMENT CONTAINER
[0001] The present application claims the benefit of U.S. Provisional Application
Serial No. 61/414,695 filed 17 November 2010, which is incorporated herein by reference in its entirety.
[0002] 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.
[0003] Typically, 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 effectiveness over a product that is mixed prior to shipping. Applications for such containers include, but are not limited to, storage of cosmetic creams and lotions, skin cleaners, shampoos, conditioners and hair coloring. While many two compartment containers exist, many contain complicated stopper configurations such as US Patent
No. 5,692,644 while some require the user to actually connect the two containers prior to mixing, see for example US Patent No. 6,910,573.
[0004] Many of the two-compartment containers in the prior art require the user to screw the mechanisms together, see for example, US Patent No. 6,126,032 or to use a driving force to cause the mechanisms to mix See US Patent No. 5,692,644. Such an action often times requires the user to exert significant force to cause the mixing.
Accordingly, a need exists for a two-compartment container that requires minimal effort to mix the two ingredients and that does not dispense a stopper within the main compartment.
[0005] Further, it has been determined that by presenting the mixing of the two ingredients in a particular way certain qualities associated with the product may be enhanced. For example, if the ingredients to be mixed are intended to reduce the signs of aging, one may wish to present them in such a manner as to convey a “fountain of youth” for example. Similarly, by representing the ingredients to the user in the form of a fountain might convey a sense of nature or purity. Traditional two compartment containers are not concerned with the impressions and feelings experienced by the user during the mixing of ingredients and therefore do not present the user with a container that allows the user to observe the mixing of ingredients.
[0006] Accordingly, a need exists for a two compartment container that allows a user to easily mix the separated ingredients, that does not leave any stoppers or other foreign matter in the main compartment and/or that allows the user to observe the mixing of ingredients. Furthermore, a need exists for a two compartment container that allows the ingredients to be mixed in such a manner as to elicit a specific response from the user. Further a need exists for a two compartment container that creates an impression of a fountain when the two ingredients are mixed. The present disclosure addresses those needs.
[0007] 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.
[0008] The fluids may be liquids or gases or a combination of liquids and gases.
Examples of fluids include water based liquids, alcohol based liquids, oil based liquids, petroleum based ointments, viscous liquids, such as gels, oils, and ointments.
[0009] 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. lt 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.
[0010] 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.
[0011] In the present invention, 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. In particular, by utilizing 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 compartments 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.
[0012] Once mixed, 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.
[0013] In one embodiment, 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. 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. At the top of the lower compartment is a valve that is formed from a solid disc of polyethylene material although other valve configurations are possible such as a diaphragm valve, a duck bill valve, a flapper valve, etc., or any valve that will contain the second fluid until mixing is desired. Likewise, the valve may be made of other materials, such as latex, plastic, rubber, etc. Above the valve is a valve adapter. The 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.
[0014] 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. Upon release of 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. Thus, when the fluid is forced against the valve upon release of the first spring, the force exerted against the second spring by the valve is greater than the spring constant which results in compression of the second spring and lifting of the valve from the top of the cylindrical extension. Other tensioning mechanisms might be, for example, the valve itself or the valve adapter composed from compressible materials. In the present embodiment, 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.
[0015] In an embodiment, 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.
[0016] In another embodiment, 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.

[0043] FIG. 1 depicts two-compartment container 100 in accordance with an exemplary embodiment. Two-compartment container 100 is comprised of an upper portion 200 containing top cap 1, dispenser bulb 2, outer neck cap 3, inner neck cap 4,
shoulder band 5, upper piston 6, dispenser tube 7 and upper compartment 8. Two- compartment container further comprises a lower portion 300 comprised of disk 9, valve adapter 10, valve 11, lower piston 12, piston adapter 13, lower compartment 14, base 15, packing ring 16, o-ring 17, pad 18, retaining spring 19 and release spring 20.
[0044] In one embodiment, lower compartment 14 sits on lower piston 12 that is surrounded by a compressed release spring 20 or other tensioning mechanism that is held in compression by a latch mechanism of lower compartment 14 and base 15.
Upon turning base 15, the latch mechanism releases release spring 20 which forces lower piston 12 upward which in turn compresses the fluid stored in lower compartment 14 and forces the fluid upward. For purposes of this embodiment, the fluid in the lower compartment is a liquid and the fluid in the upper compartment is a liquid. At the top of the lower compartment is valve 11 that is formed from a solid disc of polyethylene material although other valve configurations are possible such as a diaphragm valve, a duck bill valve, a flapper valve, etc. or any valve that will contain the second fluid until mixing is desired. Likewise, the valve may be made of other materials, such as latex, plastic, rubber, etc. Above valve 11 is valve adapter 10 and disk 9. Valve adapter 10 has a single opening that is slightly inward of the outer edge of valve adapter 10. 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.
[0045] Valve adapter 10 interposes between a transition chamber located above valve 11 and upper compartment 8 of container 100. The valve includes a lip that sits on the top a cylindrical extension of the lower compartment. Upon release of retaining spring 20 or other tensioning mechanism, the second fluid is forced upward against valve 11. Valve 11 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.
Thus, when the fluid is forced against valve 11 upon release of retaining spring 20, the force exerted against retaining spring 19 by valve 11 is greater than the spring constant which results in compression of retaining spring 19 and lifting of valve 11 from the top of the cylindrical extension. Other tensioning mechanisms might be, for example, the valve itself or the valve adapter composed from compressible materials. In the present embodiment, the pressure resulting from decompression of the release spring 20 causes the fluid from lower compartment 14 to force valve 11 upward and passes the lip of valve 11 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.
[0046] 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.
[0047] FIG. 2 shows upper portion 200. Dispenser bulb 2 has an outside surface and an inside surface 21, thereby creating cavity 22. Dispenser bulb 2 is intended to be press fit into inner neck cap 4 and is molded with notch 23 and rim 24. Notch 23 and rim 24 pressingly mate with tab 43 thereby creating gap 44 between inner neck cap 4 and upper compartment 8. Packing ring 16 fills gap 44 creating a flat seating surface 161 to allow the dispenser assembly to rest on the neck of upper compartment 8.
Packing ring 16 is a washer shaped ring having a top, a bottom and an inner and outer circumference. Inner neck cap 4 is a generally cylindrical open tube having a reduced opening 42 on the top to allow bulb dispenser 2 to pass though. Inner neck cap 4 has an interior surface 43 and an outer surface 45. Interior surface 43 contains screw threads 41 that mate with screw threads 81 on upper compartment 8. Outer neck cap 3 is a generally cylindrical tube with a reduced opening 31 at the top to allow bulb dispenser 2 to pass through the opening and is generally open at the bottom. Outer neck cap 3 is conformed to fit in direct contact with inner neck cap 4 on all exterior surfaces. Outer neck cap 3 may be manufactured from a material different then inner cap 4, such as aluminum or a different plastic coated with a reflective surface, although other esthetically pleasing materials are contemplated.
[0048] Dispenser tube 7 contains an open top end 71 adjacent to dispenser bulb 2 and an open distal end 72 that is housed within upper compartment 8. Distal end 72 may terminate in an end 75 that is bulb shaped, straight, or curved. Dispenser tube 7 has a shoulder 73 located adjacent top end 71. Shoulder 73 mates into grove 25 on dispenser bulb 2, creating a press fitting. Dispenser tube 7 is hollow and contains inner cavity 74 for drawing in fluid contained in upper container 8.
[0049] In one embodiment a piston is located above the fluid contained in the upper compartment. FIG. 3 depicts upper piston 6. Upper piston 6 contains a substantially flat bottom piston face 61 and top piston face 62, stem portion 63 which has an inner surface 64 and an outer surface 65. Surrounding the radial outer surface of piston face 61 and 62 is groove 66 for receiving o-ring 17. O-ring 17 forms a fluid tight seal with wall 84 of upper compartment 8, thereby preventing fluid from passing above upper piston 6 into cavity 82. Inner surface 64 of piston stem portion 63 forms a hollow tube for conveying there through dispenser tube 7 and accordingly access to the fluid in upper container 8. Adjacent the distal end of stem portion 63 is flare 67. At its widest exterior point, piston stem 63 is the same diameter as the inner surface of neck 83 of upper container 8. Flare 67 provides a contacting surface between upper piston 6 and neck 83 as piston 6 is forced into cavity 82. In operation, as the fluid from the lower compartment 14 is driven into the upper compartment 8 by lower piston 12, upper piston 6 is forced upwardly into cavity 82.
[0050] Upper container 8 seen in FIG. 4 is a generally cylindrical container constructed from clear plastic, such as PCTA, glass, or other highly transparent material such as Lucite® or Lexan®. It contains screw threads 81, neck 83, first shoulder 85, wall 84, bottom side wall 86, bottom 87, opening 88 and retaining ridge 89. Bottom 87 is open to allow insertion of disk 9, valve adapter 10, valve 11, lower piston 12, piston adapter 13, lower compartment 14, pad 18, retaining spring 19 and release spring 20.
[0051] Base 15 as seen in FIGS. 5A and 5B is generally cup shaped with vertical side walls 151, substantially flat base 152, inner base 156, base notch 153, teeth 154,
teeth rim 155 and open top 157. In one embodiment, side wall 151 may have a transparent window 158 or other opening to provide indication that base 15 has been rotated from its starting position with respect to the upper compartment 8. After disk 9, valve adapter 10, valve 11, lower piston 12, piston adapter 13, lower compartment 14, pad 18, retaining spring 19 and release spring 20 are inserted into bottom side wall portion 86 through opening 87. Base 15 is press fit into place with upper compartment 8 by inserting side wall portion 86 into open top 157 of base 15 until base notch 153 engages retaining ridge 89, thereby mating base 15 onto upper compartment 8. In this configuration, as will be explained more fully below, the interconnection of base notch 153 and retaining ridge 89 allow base 15 to be axially rotatable with respect to upper container 8.

In one embodiment lower compartment 14 is filled with a fluid and fitted into base 15. Base notch 146 and base lip 147 mesh with teeth 154, and teeth rim 155 of base 15. In one embodiment, the rotation of base with respect to upper compartment 8 causes teeth 154 to engage base notch 146 causing lower compartment 14 to rotate as base 15 is rotated. As will be explained further, with respect to a particular embodiment, such rotation releases the trigger mechanism releasing the energy in spring 20 and forcing the second fluid into the first compartment.
[0053] FIG. 7 depicts top cap 1. Top cap 1 is a generally cylindrical hollow cap with a solid top portion 701 on one end and an open portion 702 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. Top cap 1 may be any shape such as square, trapazoidal, oval, dome, or conical, or any other geometries as will be appreciated by those skilled in the art.
[0054] FIG. 8 depicts outer cap 3. Outer cap or neck cap 3 is a generally cylindrical tube with a reduced opening 31 at the top 350 to allow bulb dispenser 2 to pass through the opening and is generally open at the bottom 351. Outer neck cap 3 is conformed to fit in direct contact with inner neck cap 4 on all exterior surfaces. Outer neck cap 3 may be manufactured from a material different than inner cap 4, such as aluminum or a different plastic coated with a reflective surface, although other esthetically pleasing materials are contemplated.

Bottle disk 9 is generally cylindrical and circumferentially surrounded by side wall 90, containing wall notch 91, upper notch 92, lip 93, disk notch 94, valve adapter notch 96, valve adapter wall 97, center opening 98, and valve shelf 99. FIG. 14 depicts valve 11 which sits in contact with valve shelf 99. Valve 11 is generally cylindrical and contains a top lip 111 that is larger then the base 112. Base 112 is sized to fit within center opening 98 of bottle disk 9 with top lip 111 sufficiently large enough not to pass through center opening 98. Top lip 111 rests on valve shelf 99 and is held closed by retaining spring 19.
[0059] FIG. 13 depicts valve adapter 10. Valve adapter 10 is generally cylindrical and contains openings 100. Valve adapter 10 is sized to fit within bottle disk 9 resting on lip 93. openings 100 in Valve adapter 10 are circumferentially placed around valve adapter 10 such that when the tension in release spring 20 is released, the liquid in the bottom bottle passes through valve openings 100 causing the mixing of the two fluids in the upper bottle. Interposed between valve adapter 10 and bottle disk 9 are valve 11 and retaining spring 19. Retaining spring 19 is sufficiently strong to keep valve 11 closed until the tension in spring 20 is released. Once it is desired to mix the liquids and the tension in release spring 20 is released, the expansion force in retaining spring 19 is insufficient to keep valve 11 in a closed position such that the fluids are forced to be mixed in the upper container.
[0060] FIG. 15 depicts an embodiment of lower piston 12. Lower piston 12 is generally cylindrical having piston side walls 120, piston face 121, piston bottom 122, piston stem 123, piston rim 124, piston notch 125 and piston lip 126. The diameter of piston 12, including piston face, 121, piston rim 124, piston notch 125 and piston lip 126 is such that it fits inside lower compartment 14 and contacts the inner surface of sidewalls 151. In the depicted embodiment, piston side walls 120 circumferentially extend down from piston face 121 and taper to a chiseled flared end 127. Flared chiseled end 127 ensures contact between piston side walls 120 and inner compartment side walls 151. While this specific piston configuration is depicted, it should be appreciated by one skilled in the art, that other piston configurations are possible. For example, piston face 121 could extend the full diameter of the piston face without the need for piston rim 124, piston notch 125 and piston lip 126. Likewise, a sealing ring or other means could be utilized in place of side walls 120 and chiseled end 127 to ensure a tight fit with respect to sidewalls 151 of lower compartment 14.
[0061] FIG. 16 depicts piston adapter 13. Piston adapter 13 is generally cylindrical and hollow with an inner portion 133, an upper portion 130 and a lower portion 131.
