Description

This application is a continuation of U.S. application Ser. No. 12/418,498 files Apr. 3, 2009 which claims is a continuation-in-part of U.S. application Ser. No. 11/024,026, filed Dec. 24, 2004 and claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Ser. No. 61/042,306, filed Apr. 4, 2008, which is expressly incorporated by reference herein.

BACKGROUND

The present disclosure relates to closures, and particularly to closures for mounting on the top of bottles or other containers. More particularly, the present disclosure relates to a closure configured to dispense a solute into a solvent contained in a container coupled to the closure.

SUMMARY

A solute-dispensing closure in accordance with the present disclosure is adapted to be coupled to a filler neck of a container. The solute-dispensing closure can be operated to discharge a solute into a solvent stored in the container.

In illustrative embodiments, the solute-dispensing closure includes a solute-carrier cartridge mounted for movement in a tubular inner guide from a raised solute-storage position to a lowered solute-dispensing position. The tubular inner guide is included in a cartridge-support body that is adapted to mount on a container filler neck to place the tubular inner guide in fluid communication with any solvent stored in an underlying container. A cartridge-piercing unit is coupled to a lower end of the tubular inner guide and arranged to puncture a downwardly moving solute-carrier cartridge to produce a solute-dispensing opening in the solute-carrier cartridge freeing any solute carried in the cartridge to flow into the solvent stored in the container.

In illustrative embodiments, the solute-carrier cartridge is arranged in the tubular inner guide to extend upwardly through a top aperture formed in the tubular inner guide to cause an exposed portion of the solute-carrier cartridge to lie outside the tubular inner guide when the solute-carrier cartridge is retained in the raised solute-storage position. In use, a consumer can easily apply an external impact force (using, for example, the palm of the consumer's hand) to dislodge the solute-carrier cartridge and move it downwardly in a cartridge-guiding passageway formed in the tubular inner guide to engage and be punctured by the cartridge-piercing unit. Once solute carried in the solute-carrier cartridge is discharged into solvent extant in the companion container, the consumer can shake the container vigorously to dissolve the solute in the solvent to produce a drink mixture in a solvent reservoir formed in the container.

In illustrative embodiments, a removable outer lid is coupled to the cartridge-support body. The outer lid is configured to cover the exposed portion of the movable solute-carrier cartridge to shield the movable solute-carrier cartridge from exposure to a premature external impact force to block premature movement of the solute-carrier cartridge to engage the cartridge-piercing unit and cause premature puncture of the solute-carrier cartridge and discharge of solute carried therein into an underlying pool of solvent in a container coupled to the cartridge-support body.

Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.

DETAILED DESCRIPTION

A package 10 in accordance with the present disclosure includes a container 12 and a solute-dispensing closure 14 coupled to container 12. As suggested in FIGS. 2 and 4, solute-dispensing closure 14 includes a solute-carrier cartridge 16 formed to include an interior solute-storage region 18 containing a solute 20. As suggested in FIGS. 3 and 5, solute-carrier cartridge 16 is mounted for movement in vertical cartridge-guiding passageway 22 formed in a cartridge-support body 24 included in solute-dispensing closure 14 and coupled to container 12. Once solute-carrier cartridge 16 is moved in a downward direction 26 in cartridge-guiding passageway 22, it is punctured by a cartridge-piercing unit 28 included in solute-dispensing closure 14 to cause solute 20 to be dispensed into solvent 30 stored in container 12 through an opening 32 formed in solute-carrier cartridge 16 as shown best in FIG. 5.

Once a user has applied a downward external impact force 101 to cause solute-carrier cartridge 16 to move downwardly and be punctured by underlying cartridge-piercing unit 28 to cause solute 20 to be dispensed into solvent 30, the user is instructed to shake package 10 to hasten the rate at which solute 20 dissolves in solvent 30 to produce a drink mixture in an interior solvent-storage region 50 formed in container 12. The user then removes solute-dispensing closure 14 from a filler neck 13 included in container 12 so that the user can access and consume the drink mixture. Should the user elect to store unconsumed drink mixture in container 12, solute-dispensing closure 14 or any other suitable filler-neck closure can be coupled to filler neck 13 to close an opening into the interior solvent-storage region 50 formed in container 12.

Solute-carrier cartridge (or cap) 16 includes an inverted cup 34 and a sealing member 36 coupled to a brim 38 of cup 34 to define interior region 18 of solute-carrier cartridge 16 as shown, for example, in FIGS. 4 and 7. Solute 20 is deposited into a cavity 40 formed in cup 34 before sealing member 36 is coupled to brim 38 of cup 34 to retain solute 20 in interior region 18. It is within the scope of this disclosure to use a powdered (as shown) or liquid solute to define solute 20 or to use any other suitable fluid solute.

Cup 34 in solute-carrier cartridge 16 includes a round end wall 341 and a cylindrical side wall 342 coupled to a perimeter edge of round end wall 341 in an illustrative embodiment as shown, for example, in FIG. 1.
