Concentrate cartridge for sport drink

1. A concentrate cartridge comprising:

a hollow main body having a first open end forming a closure seat and a spaced apart second end including a neck finish including threads formed on an outer surface thereof, a closure cap having threads formed on an inner surface thereof adapted to engage threads formed on an outer surface of a neck finish of a diluting and dispensing container, an annular collar, and an annular web having a generally U-shaped cross-section interconnecting the collar and the neck finish of the hollow main body;

a hollow tube having a first end portion in substantially fluid-tight sliding relation with the main body, and a second end portion including a radially outwardly extending closure adapted to selectively seat with the closure seat of the main body to form a substantially fluid-tight closure therebetween; and

a closure valve member having a hollow cylindrical skirt provided with threads formed on an inner surface thereof adapted to engage the threads of the neck finish of the hollow main body, wherein the closure valve member includes a hollow cylindrical sleeve adapted to be received within the neck finish of the main body.

2. A concentrate cartridge body, cap, and valve for a diluting and dispensing container comprising:

a hollow main body having a first open end forming a closure seat and a spaced apart second end including a neck finish having threads formed on an outer surface thereof, an annular collar, an annular web having a generally U-shaped cross-section interconnecting the collar and the finish, and a cap having threads formed on an inner surface thereof adapted to engage threads formed on an outer surface of a neck finish of a diluting and dispensing container, wherein an inner surface formed by the juncture of the annular collar and the annular web is inclined inwardly and upwardly from an inner surface of a hollow portion of the main body to an inner portion of the neck finish of the main body;

a hollow tube having a first end portion in substantially fluid-tight sliding relation with the main body, and a second end portion including a radially outwardly extending closure adapted to selectively seat with the closure seat of the main body to form a substantially fluid-tight closure therebetween;

a closure valve member including a hollow cylindrical skirt provided with threads formed on an inner surface thereof adapted to engage the threads of the neck finish of the main body, and a hollow cylindrical sleeve adapted to be received within the neck finish of the main body for engagement with the hollow tube, wherein a one-way valve forms the terminus of the hollow interior of the sleeve; and

a means to militate against an undesired tightening of the closure valve member and release of a concentrated material into the diluting and dispensing container.

3. The concentrate cartridge body, cap, and valve for a diluting and dispensing container according to claim 2 , wherein the means to prevent tightening of the closure valve member and release of the concentrated material into the diluting and dispensing container is a plastic safety seal.

4. The concentrate cartridge body, cap, and valve for a diluting and dispensing container according to claim 2 , wherein the main body and hollow tube are produced from polypropylene.

5. A concentrate cartridge assembly comprising:

a cartridge including a hollow main body having a first open end forming a closure seat and a spaced apart second end having a flange formed around the outer peripheral surface, and a hollow tube having a first end portion in substantially fluid-tight sliding relation with the main body, and a second end portion including a radially outwardly extending closure adapted to selectively seat with the closure seat of the main body to form a substantially fluid-tight closure therebetween;

a means to couple including a neck finish having threads formed on an outer surface thereof, an annular collar, an annular web having a generally U-shaped cross-section interconnecting the collar and the neck finish of the means to couple, and a cap having threads formed on an inner surface thereof adapted to engage threads formed on an outer surface of a neck finish of a diluting and dispensing container; and

a closure valve member including a hollow cylindrical skirt provided with threads formed on an inner surface thereof adapted to engage the threads of the neck finish of the means to couple, and a hollow cylindrical sleeve adapted to be received within the neck finish of the means to couple, a one-way valve forming a terminus of the hollow cylindrical sleeve, wherein the means to couple facilitates a coupling of the closure valve member to the cartridge.

6. The concentrate cartridge assembly according to claim 5 , wherein a juncture of the annular collar and the annular web forms a recess adapted to receive the flange of the cartridge.

7. The concentrate cartridge assembly according to claim 5 , wherein the cartridge is adapted to contain a concentrated material.

8. The concentrate cartridge assembly according to claim 7 , wherein the second end of the main body further includes a means to prevent tightening of the closure valve member and release of the concentrated material into the diluting and dispensing container.

9. The concentrate cartridge assembly according to claim 8 , wherein the means to prevent tightening of the closure valve member and release of the concentrated material into the diluting and dispensing container is a plastic safety seal.

10. The concentrate cartridge assembly according to claim 5 , wherein the main body and the hollow tube are produced from polypropylene.
