BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an ingredient dispensing cap that is mounted on a primary container for storing ingredients to be dispensed into the primary container contents at time of use, and specifically to a dispensing cap having an ingredient storage chamber and a push-pull drink spout (with a drink through passage) that is used to dispense the stored ingredients.

2. Description of Related Art

Many beverages, cleaning products, oil products, pharmaceuticals, and other chemicals and substances, do not retain their stability, strength, and effectiveness, for long after the ingredients have been mixed in a solution or suspension with a different liquid or substance. Many liquids, gels, or acquiesce type solutions are formulated for shelf life rather than for quality, effectiveness, and potency of a product. In many cases, ingredients such as: stabilizers, fillers, preservatives, binders, and other types of chemicals and substances are added that now can be reduced or eliminated by this invention. This reduced shelf life after mixing mandates that the mixed product be utilized relatively soon after mixing to obtain full strength and effectiveness, to prevent loss of effective strength, deterioration, discoloration, interactions between ingredients and reduced effectiveness. Also it is estimated that 60 billion empty bottles go into landfills in the United States every year. A liquid dosing cap with concentrate can be used to allow a consumer to use a reusable bottle, reducing the problem of empty bottles in landfills.

A dispensing cap can be used for any primary container to store different ingredients to be mixed in the primary container. The dispensing cap includes its own ingredient storage and release chamber. Any ingredients that are stored in the dispensing cap can be dispensed into any container (whether threaded, snapped or adhered to any type of primary container) for mixing with the container contents manually by an individual when ready for use. The shelf life of the combined ingredients in this invention can be extended indefinitely. The dispensing cap can be used as a storage chamber of one or more storage tanks in a dosing cap to release a combination of liquids and or powders for any ingredients that can be admixed with any other contents that are stored in a primary container.

Many current bottle caps include a drinking spout and flow valve to allow the user to drink directly from the primary container. Water bottles are good example that includes caps with drinking spouts. The invention disclosed herein provides for a dispensing cap that includes a drink through drinking spout and liquid or semi liquid flow valve that is also used to activate the ingredient dispensing into the primary container.

Applicants' U.S. Pat. No. 6,644,471, issued Nov. 11, 2003, describes a dispensing capsule that permits drinking through the dispensing capsule. Applicants' pending patent application, U.S. Ser. No. 12/649,438, filed Dec. 30, 2009, describes a drinkable storage and dispensing ingredient cap.

BRIEF SUMMARY OF THE INVENTION

A dispensing cap with one or more chambers combined for storing and releasing one or more ingredients into a primary container. The dispensing cap includes a drinking spout.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings and in particular FIG. 1, the present invention is shown at 10 including a cap body 12 to which a dust cover 14 is attached. The cap body 12 is attached to a primary container 16. The container neck threads 16a are partially shown.

The primary container 16 can be a bottle or other type of container that houses an ingredient such as a liquid. The cap body 12 contains one or more ingredients that upon activation will be dispensed into the contents of primary container 16 at time of use. After the cap body dispensing has been activated, the cap body also has a drinking spout and valve to allow the user to drink directly from the primary container 16 through the cap body 12. The user can also close the drinking valve after the cap body 12 has been activated to prevent liquid form spilling out of container 16.

Referring now to FIG. 2, the invention is shown at 10 comprising dispensing cap 12 and dust cover 14. The dispensing cap 12 includes fastening threads or any kind of attachment which allows the cap 12 to be threadably fastened to primary container 16 over container opening 16b and attachable to primary container threads 16a. The dispensing cap 12 includes a push-pull drinking spout 18 that also includes an open/close liquid flow valve 18aa that can be manually positioned by the user. Once the ingredients in the dispensing cap 12 have been activated, the user can drink directly from the primary container 16 through cap 12 and drinking spout 18. The dispensing cap 12 includes a cap body for storing ingredients that includes activating member 12c and resilient octagonal wall 12b that connects the activating member 12c to the ingredient storage chamber 24 formed by cylinder 12d. The cap body includes a cap cylindrical wall 12a that is used to manually twist the cap 12 on or off the primary container 16. The dust cover 14 is removed before use.

Referring now to FIG. 3, the invention 10 is shown in cross-section. An important feature of the dispensing cap is the use of two seals to encapsulate the ingredients stored in the dispensing cap before use. The ingredients are protected by the two seals (upper and lower) from moisture and the ambient environment until the time of use when both seals are ruptured. FIG. 3 shows both the upper seal 22, which is a molded plastic liquid barrier, and lower aluminum foil seal 20 intact and/or a line of weakening.

The aluminum foil seal 20 may be attached to the cylinder 12d by electromagnetic (RF) energy that heats the foil or any other means of attaching. A plastic barrier could be attached by ultrasonic welding in lieu of a foil seal or in combination thereof 20 or a molded plastic barrier could be used with a line of weakening.

The dust cover 14 is shown as a snap in-place using an annular lip 14a that snaps into a recess in the body 12a top edge. The dust cover 14 prevents the dispensing cap 12 from being accidentally activated until the dust cover is removed because of the rigidity of the dust cover 14 and to help eliminate any contaminates to adhere to the drinking spout during storage. The dispensing activating member 12c is shielded from contact when the dust cover 14 is in place. Therefore, the dust cover 14 is a very important element of the present invention to prevent the dispensing cap from being activated accidentally before the time of use.

The dispensing cap 12 has an annular cylindrical wall 12a that includes fastening threads or other means 12aa disposed on the inside surface of the annular wall 12a which are used to fasten the dispensing cap 12 to a primary container neck 16c that also has fastening threads 16a. The dispensing cap wall 12a is integrally constructed with an ingredient storage chamber 24 formed by cylinder 12d and are molded as one piece. A thin octagonally-shaped flexible wall 12b is connected at its base to cylinder 12d and at its top to dispensing activating member 12c. The thin octagonally shaped flexible wall 12b has flat segments forming a stair step array for up and down movement. The flexible wall 12b could be rectangular or hexagonal in shape. The activating member 12c encloses a secondary ingredient storage chamber 26 and includes one or more jagged teeth 12cc along its base which are used to break through the foil seal 20 that covers the bottom of the ingredient storage chamber 24 formed by cylinder 12d when the dispensing cap is activated. Thus, the cap body 12 is a single molded device having a cylindrical wall 12a with threaded fasteners 12aa, an ingredient storage chamber 24 formed by cylinder 12d, and a dispensing activating member 12c movably attached to the cap body wall 12a by a flexible wall 12b. The activating member 12c could have its lower section divided into two separate semi cylindrical elements each forming almost half a cylinder in shape. This would allow the ingredients stored in the cap to escape easier and more completely.

The dispensing cap 12 also includes a drinking spout 18 that has a push-pull valve to allow a user to drink the mixed contents after the dispensing cap has been activated and to close the valve to prevent liquid from flowing out when not in use. The push-pull drinking spout 18 is also used to manually depress downwardly the activating member 12c causing the foil seal 20 to be ripped open. The drinking spout 18 also includes a seal piercing element 18a. When the drinking spout 18 is pushed downwardly, the piercing element 18a pierces the molded top seal barrier 22 which then allows the liquid contents in the primary container 16 to flow into the drinking spout 18. FIG. 4 shows an enlarged view of the drinking spout piercing element 18a positioned adjacent seal barrier 22 molded with activating member 12c as part of the molded dispensing cap. When the drinking spout piercing element 18a is pushed downwardly against seal barrier 22, the barrier 22 will tear apart along lines of weakening in the center area of the upper seal to prevent the seal barrier 22 from falling into the primary container 16. The upper seal barrier 22 can also be molded with peripheral lines of weakening 22a and 22b.

Referring now to FIG. 5, the primary container 16 is filled with a liquid 28 which is the contents of the primary container 16. The attached dispensing cap 12 has ingredients 30 located both in the storage chamber 24 and the secondary ingredient storage chamber 26. The ingredients 30 to be dispensed into the liquid contents 28 of container 16 can completely fill the storage compartments of dispensing cap 12. As shown in FIG. 5, the dust cover has been removed and the dispensing cap 12 is ready to be activated.

FIG. 6 shows the invention 10 and specifically the dispensing cap 12 fully activated. The drinking spout 18 has been manually depressed downwardly, forcing the cap body dispensing activating member 12c to move downwardly, allowing the teeth 12cc to engage and rip open foil seal 20. This allows the ingredients 30 to fall or be dispersed into the primary container 16 interior which has liquid contents 28 that now mixes with the ingredients 30 at the time of use. Also shown in FIG. 6 is that the upper seal barrier 22 has also been forced open and downwardly by the piercing element 18a due to the downward movement of the drinking spout 18 and stays attached to the liquid flow area and does not disengage and fall into the container. Once piercing this seal barrier 22, the user can now drink the contents that have been mixed in primary container 16 through the drinking spout 18 that includes a passageway 18b. The wall 12b connected to the dispensing activating member 12c is shown in the downward position. The bottom end of activating member 12c can be positioned to engage the ripped seal 20 segments to ensure the ingredients empty from the cap storage and the seal 20 segments do not rise up and block the passage once torn open.

As shown in FIG. 6, the drinking spout 18 also acts as a liquid flow valve 18aa to allow the liquid contents in primary container 16 to flow through passage 18b when the liquid flow valve 18aa is open and to not flow out of the primary container 16 when the push-pull drinking spout 18 is in the closed position as shown in FIG. 6.

The dispensing cap 12 can be molded as a single piece as shown in FIG. 6 excluding the drinking spout 18 and in FIG. 14 without the drinking spout. The dispensing cap 12 also utilizes a drinking spout that can be manually activated with a push-pull action that allows the user to drink the contents directly from a primary container 16 and to close the valve so that the contents 28 and 30 cannot be spilled from primary container 16 when the device is not in use.

Referring now to FIG. 7, the dispensing cap 12 is shown in a mode of operation after the ingredients have been activated and dispensed into primary container 16. Specifically, the drinking spout 18 which operates as a push-pull is shown in the full up position after activation which allows for a liquid (the contents of primary container 16) to flow through the internal passage of the activating member 12c namely through secondary ingredient storage chamber 26, past the liquid flow valve 18aa which includes the piercing element 18a and out through the spout 18. In the configuration shown in FIG. 7, the dispensing cap is in an activated mode for drinking the mixed contents at the time of use after the ingredients that were stored in the dispensing 12 have been dispensed into primary container 16 contents.

FIG. 8 shows an alternate embodiment of the invention wherein the bottom foil seal shown in FIG. 3 as foil seal 20 has been replaced by a cup-shaped molded plastic seal 32 which includes a bottom wall 32a. The cylindrical cup seal 32 is made of a liquid barrier such as plastic or other sealing material and is sized to snuggly fit around the outside surface of cylinder 12d so that the cylinder 12d is completely sealed (air and liquid) around its open bottom by the cup-shaped seal 32.

FIG. 9 shows an additional sealing tab 32b that is the top lip of the cup seal 32 shown in FIG. 8. The cap body 12d upper perimeter has a female tab shaped recess that receives tab 32b so that once the cup seal 32 has been inserted over cylinder 12d and the tab 32b inserted in place in the female recess along cylinder 12d, the cup seal 32 is firmly in place.

Referring now to FIG. 10, the inside surface of the cup seal 32 is shown having longitudinal ribs 32c protruding inwardly to allow air to escape when the cup seal 32 is snuggly fit over the cylinder 12d shown in FIG. 8. FIG. 10 also shows the cup seal 32 having a floor 32a which is a sealed barrier for liquid or dry ingredients until the floor is ruptured by the activating member 12c.

FIG. 11 is a top plan view of the cup seal 32. The cup seal floor 32a is shown. A hinge 32aa interrupts a line of weakening 32bb to prevent wall 32a from falling into container 16 after activation and can be attached at any location of the body of the cap.

Referring now to FIG. 12a bottom plan view of the dispensing cap 12 is shown with the bottom foil seal removed. The activating member 12c is shown surrounding seal 22 which includes lines of weakening 22a in the center area of the seal. Also shown is the base of cylinder 12d which is part of the cap body. The activating member 12c that is shown is used to disperse the ingredients by tearing open the bottom foil seal (not shown).

FIG. 13 shows the drinking spout 18 in a bottom perspective view. Also shown as part of the drinking spout 18 is the push-pull piercing member 18a which is projecting from the bottom section of the push-pull drinking spout that allows flow through of liquids from a primary container through the drinking spout 18.

FIG. 14 shows a perspective view of an alternate embodiment of the invention that includes the invention 100 having a dust cover 140 tethered by band 160 to the dispensing cap 120, connected to the primary container 160 with the dust cover 140 removed from the top of the dispensing cap 120.

The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made there from within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
