The present invention relates to a dispensing closure used to house a secondary supply or dose of product and when the closure is activated dispense the secondary product or dose into a receiving vessel to which it is attached. Methods for dosing or supplying a dose of product are also provided.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates generally to the field of packages and containers, and in particular, pertains to containers having two compartments and that may be used to keep two components separate until use and dispense of one component into the other at the point of use.
2. Related Art
It is desirable to fit a device to the top of a beverage or other like product that can dose or supply a second product thereto.
Twist to open technology provides limited opening port increased operational forces and a steep learning curve for use by the end user. Ingredients housed are often compromised when the mating components are not properly aligned. This failure breaches the seal integrity for the ingredients and may not be readily known by the manufacturer or the end user. These devices may also contain multiple parts to achieve the actions needed to house product and twist to dispense. Other products require a great deal of force to open the closure and is commonly opened by slamming the head of the closure down onto a hard surface in order to breach the sealed portion of the closure thereby allowing access to ingredients. There remains a need for a storing and dispensing closure device that can store a product separately from a second product so as to retain its ingredient integrity over time and to dose or supply the product at a predetermined dose or supply into a receptacle, vessel or container for consumption without contamination or spilling, that is easily assembled, filled and operated.

DETAILED DESCRIPTION OF THE INVENTION

Detailed descriptions of embodiments of the invention are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

Inverted Press Part Dispensing Closure

In one aspect the present invention relates to novel inverted press part dispensing closure devices. The press part may be a convex dome or frustum cone that becomes inverted when pressed or activated. The inverted press part dispensing closure may be used to separately house, store or carry a dose or supply of a product or one or more ingredients to maintain freshness and integrity of the ingredients until dispensed into a separate receiving vessel. When activated the inverted press part dispensing closures of the present invention deliver the dose to the receiving vessel and allows the end user to dispense the dose or supply of product without the removal of the dispensing closure from a bottle or container thereby eliminating spills and contamination. The combined contents of the receiving vessel can be dispensed for consumption by removing the dispensing closure from the receiving vessel.
In some embodiments the inverted dome dispensing closure comprises a housing and an attachment means for attaching the inverted press part dispensing closure to a receiving vessel. In other embodiments the inverted dome dispensing closure comprises a housing, an attachment means for attaching the inverted press part dispensing closure to a receiving vessel, and a receiving vessel.

Housing

The housing of the inverted dome dispensing disclosure has a proximal top, a distal base, side walls and an internal volume. In one embodiment the side walls of the housing are curved to give the housing a tubular shape. The housing is also referred to herein as the tube or housing tube. The tubular shape of the housing may be conical including any tapered tubular form or cylindrical including an elliptic cylinder shape, parabolic cylinder shape, hyperbolic cylinder shape, circular cylinder shape and generalized cylinder (in which the cross-section may be any curve) shape. In another embodiment the side walls of the housing are flat having three or more side walls forming an angular tube shape. The angular tube shape of the housing includes a triangular shaped tube, square shaped tube, rectangular shaped tube, polygon shaped tube. The proximal top of the housing comprises a press part described in greater detail below. The distal base of the housing comprises an end cap and/or end plate seal as described in greater detail below. In some embodiments the internal volume of the housing is predetermined for dosing and supplying methods.
As shown in FIG. 6, the housing further comprises internal hollow dose chamber. The hollow dose chamber is used to house the one or more ingredients, formulations or products. The distal base of the housing further comprises a dispensing port when the closure device is activated. Upon actuation, there is provided a spaced opening at the distal end of the housing allowing one or more ingredients to exit the dose chamber and be dispensed. Ingredients
The type and form of one or more ingredients, formulations or products stored in the dose chamber is unlimited. In some embodiments there is a single ingredient, formulation or product and in other embodiments there is a combination of ingredients, formulations and/or products. Non-limiting exemplary forms of ingredients, formulations or products include powders, dehydrated constituents, liquids, liquid concentrate and suspensions. Non-limiting examples of the types of ingredients, formulations or products that can be stored and dispensed from the dispensing closure include dietary supplements (e.g., fiber and vitamins), sport nutrition ingredients (e.g., amino acids, fat burning agents, muscle builders), diet nutrition ingredients (e.g., appetite suppressants, fat burning agents, ingredients causing a feeling satiety), ingredients with anti-aging benefits, immune supporting ingredients (e.g., prebiotics, probiotics), energy boosting agents, stimulants, anti-oxidants.
The ingredients capable of being stored and dispensed from the dispensing closure device can also include medicaments, drugs and pharmaceuticals. It is desirable to formulate a point of use form of delivering medicine that avoids the need to swallow hard tablets, capsules, avoids bad taste associated with more traditional forms of medicines and maintains the product integrity.
Any of the one or more ingredients or products stored and dispensed by the dispensing closure device of the present invention may be store independently or in combination with other ingredients, flavoring, sweetening, acidulants, excipients, preservatives and/or coloring agents.
The housing further comprises a user-actuated means for dispensing the one or more ingredients. In another embodiment the dispensing means comprises a press part, a septum and an end cap. In another embodiment further comprises an end plate seal. In another embodiment the dispensing means comprises a press part, a septum, a septum end attachment and end plate seal. In some embodiments the dispensing means comprises a press part having a convex dome shape. In some embodiments the press part is a frustum cone shape. The dispensing means is intended to be actuated at the point of use by an end user. The end user activates dispension by applying a force to the convex press part. The end user applies a pressing force to the convex dome or frustum cone causing inversion into a concave configuration. In one embodiment, movement of the press part into a concave configuration applies a force on to the septum causing the septum to move in a distal direction and press upon the end plate seal, end cap or septum end attachment. In one embodiment, the force of the septum pressing upon the end plate seal causes the end plate seal to shear, break or fracture. In another embodiment, the force of the septum pressing upon the end cap causes the end cap to shear, break or fracture the end plate seal and move beyond the distal end of the housing. In another embodiment, the force of the septum pressing upon the septum end attachment causes the septum end attachment to shear, break or fracture the end plate seal and hold the flexible end plate seal within the radial beads positioned to the inside of the cupped end of the septum end attachment. In all embodiments, there is created a spaced opening in the distal end of the housing allowing one or more ingredients to exit the dose chamber and be dispensed.

Closure Radial Skirt

The housing is attached to a closure radial skirt. The closure radial skirt serves to attach the inverted dome dispensing closure device to a receiving vessel capable of receiving the one or more ingredients dispensed from the housing. The closure radial skirt has a greater diameter than the housing. The closure radial skirt has a proximal upper deck, peripheral side walls, and a distal annular edge. As shown in FIGS. 3 and 6, in one embodiment there are longitudinal finger recess elements on the outer side walls of the closure radial skirt for better grasping by the end user. In one embodiment, the closure radial skirt has threads on the internal side walls capable of being rotatably coupled to a receiving vessel opening. In another embodiment the closure radial skirt is non-threaded. In some embodiments, the closure comprises a depending radial flexible member that fits to the inner diameter of a receiving vessel opening. The depending radial member is designed to have interfering engagement with the inner diameter of the opening of a receiving vessel such that it seals the contents of the receiving vessel from leaking out and still allows sufficiently low application and removal forces to be readily applied and removed by the end user. As shown in FIG. 8, in one embodiment there is a flexible depending radial member referred to as the plug seal capable of plugging the opening of a receiving vessel. This seal protrudes inside the opening of a receiving vessel keeping its contents secure from leakage.

Press Part

The press part is located at the proximal top of the housing and is the component actuated by the end user. In one embodiment, the press part is a convex dome, as shown in FIGS. 3, 6, 8-11, and 13-15. In one embodiment the press part is a frustum cone as shown in FIGS. 21 and 22. The press part is made of a thin uniform wall of material that can be readily deformed into an inverted concave configuration when sufficient force is applied to it. Applying a force against the press part to cause a concave configuration initiates the dispensing. In some embodiments the end user actuates the dispensing by applying a force against the press part causing the press part to depress into an inverted concave configuration.
In some embodiments the convex dome press part is configured with a plurality of radial hinge members that are spaced apart throughout the arc of the dome. In some embodiments there are radial hinge elements placed at the upper radial edge of the tube, at the upper radial edge of the septum and combinations thereof, as shown in FIG. 8. The radial hinges are configured in a manner to allow the convex dome to flex to a maximum inverted position. When the convex dome is molded in anything but white colored material, the flexing portion of the dome creates a crease at the areas where the dome bends. The whitening is a function of the material or resin used to mold the press point. The crease is also influenced by the design of fillet radii in that flexing area. One skilled in the art will know the specific geometry needed to make sure these areas bend or flex without shearing as the material is stressed beyond its natural elastic limits at the outer and inner portions of the dome.
In some embodiments the underside of the convex dome has supporting axial ribs, radial ribs or combinations thereof. The supporting dome ribs provide actuation feel for the end user.
In other embodiments, the frustum cone press part having a general convex shape and capable of being pressed into a concave configuration is configured with radial hinges, axial ribs, radial ribs or combinations thereof.

Septum

At the apex of the press part there is a depending septum extending towards the distal base of the housing as exemplified in FIGS. 3, 8 and 15. In some embodiments the septum is integrally molded to the underside of the press part. In some other embodiments the septum is interferingly engaged with the underside of the press part. The septum is actuated by the inverted press part pressing on its proximal end and moving it toward the distal base of the housing. In some embodiments, the distal end of the septum is configured to receive an end cap in mating engagement. In other embodiments, the distal end of the septum is attached to a septum end attachment. The septum is configured to be in axial alignment with the housing in an non-activated state and maintains axial alignment during actuation of the dispensing means and accepting of the end cap.
The septum is substantially rigid and not intended to bend or flex to a deformable position. The rigidity of the septum aids assembly so that it can readily accept the end cap as there is interfering engagement in between the septum and the end cap. The end cap is intended to remain engaged in the septum and not readily removed from the septum. As the press part is inverted the septum forces the end cap in a downward direction beyond the distal base of the dose chamber and housing. The strength of the septum needs to be structurally sound enough to forcibly remove the end cap from the product chamber where there is diametrical interference.

End Cap

The end cap is located at the distal base of the housing and is mating engagement with the distal end of the septum as exemplified in FIGS. 8 and 15. In some embodiments the end cap is configured to receive the distal end of the septum in a recess to maintain axial alignment within the housing. In other embodiments the septum is configured to receive the proximal end of the end cap. The end cap is in interfering engagement with the internal side walls of the housing sufficient to provide sealing integrity alone and maintain the one or more ingredients in the dose chamber of the housing tube. In some embodiments, the end cap is comprised of propylene and ethylene materials. In some embodiments the end cap and internal side walls of the housing tube are made of a highly polished mating surfaces. These highly polished faces when in intimate contact provide superior seal integrity against moisture and maintain product integrity. Such polishing methods are known to one of skill in the art.
The end cap can be configured to include a liner in between the end of the septum and the bottom portion of the end cap to provide sealing interface and added removal resistance. A small foil disc with materials coated on the outside is cut and placed into the bottom of the recess formed to accept the septum. The liner welds to both portions the end cap and the septum using an RF (radio frequency) sealing process common in the foil liner applications. This process is very similar to the foil liner found on catsup bottles only the liner can be configured to seal both portions. When other portions are welded with this type of liner the strength of the weld is very strong and the end cap cannot be readily separated from the septum. The advantage is this avoids spin welding which would weld the outer portion of the end cap to the product chamber. Sonic welding and heat stake welding processes are not directional enough to avoid heating the adjacent areas of the product chamber and end cap thus adhering them together.

End Plate Seal

In some embodiments an end plate seal is used to provide a protective seal at the distal base of the housing. The end plate seal extends across the distal base of the housing tube as exemplified in FIGS. 3 and 8. The end plate seal may be made from a variety material that are thin and frangible in nature to fracture when the press part is inverted to a concave shape causing the engaged septum to apply a force against the end cap causing force against the end plate seal. In some embodiments a foil liner is applied at the distal base of the end cap and distal base of the housing tube to seal the interior of the housing tube. The closure created by the end plate seal is used to add to product efficacy and provide tamper evidence if prematurely breached.
In other embodiments the foil end plate seal is supported by plastic across the entire face of the foil to provide sufficient mechanical support to pass common shipping, filing and drop tests and to maintain product integrity. Use of a supporting plastic also allows for a majority of the foil to by intimately attached to both the polypropylene (PP) and high density polyethylene (HDPE) polymers used to mold the inverted dome dispensing closure device components thereby reducing the amount of foil particulates falling into the receiving vessel upon dispension.

Septum End Attachment

In some embodiments the inverted dome dispensing closure further comprises a septum end attachment as exemplified in FIG. 6. This separate attachment is used to capture a foil type of an end plate seal. The septum end attachment is configured in a manner to apply uneven pressure on the end plate to reduce the force required to fracture or open the end plate. The septum end attachment is generally reduced in diameter from the dose chamber to allow free movement of the septum and dome inversion. The septum end attachment is configured to include one or more radial beads and is largely cupped in configuration. Once the dome is inverted the septum end attachment acts against the end plate in sufficient force to break-away the end plate seal. The end plate seal being flexible enough to accept the cup shaped septum end attachment and hold the flexible seal within the radial beads positioned to the inside of the cupped end of the septum end attachment.

Receiving Vessel

The receiving vessel may be any container, receptacle, vessel of varying size and shape capable of being attached to the dispensing closure devices of the present application. It may be constructed from glass, plastic or other similar material. In some embodiments the receiving vessel has a threaded neck for attachment thereto. In some embodiments the receiving vessel is attached to a dispensing closure of the present invention by a manufacturer. In other embodiments the receiving vessel is attached to a dispensing closure device of the present invention at the point of use by an end user. In some embodiments the receiving vessel has a pliable seal at the land of the vessel opening that can be removed by an end user at point of use before attachment. The pliable seal at the land of the vessel opening is used to maintain product integrity of the receiving vessel. In other embodiments the receiving vessel has a removable screw cap or such other removable top that once removed it is capable of attaching to the dispensing closure devices.
Non-limiting exemplary receiving vessels include bottles, other beverage containers, cartons, canteens, stand-up pouches, cans, flasks, glass bottles, and the like.
The type and form of one or more ingredients of the receiving vessel is unlimited. Non-limiting exemplary forms of ingredients of the receiving vessel includes beverages, drinks, infusions, liquids, shots, suspensions, syrups and swills. Non-limiting examples of the one or more ingredients of the receiving vessel include water, sports drinks, meal replacement beverages, diet beverages, energy drinks. The receiving vessel may also contain excipients, acidulants, sweeteners, flavoring agents and coloring agents for easier consumption by the end-user of a medicament, drug or pharmaceutical dispensed therein.

Materials

In some embodiments, the materials of the inverted dome dispensing closure device are primarily comprised of propylene and ethylene materials or combinations thereof. In some embodiments the material is polypropylene (PP) and/or polyethylene (PE) materials. In some embodiments the material is a high density polyethylene (HDPE). Alternate materials of flexible nature can also be employed like thermoplastic elastomers and others of a lower modulus sufficient to provide flexibility.

Tamper Evident and Protective Components

It is another aspect of the invention to provide a point of use dispensing closure device that indicates to the end user whether inadvertent dispension or tampering with the product has occurred and that protects from accidental, inadvertent or premature dispension.

Inverted Dome Configuration

The convex dome itself is configured to indicate tampering. The convex dome is designed in such a manner as to not be readily re-inverted, or moved from a concaved activated position back to a convex armed and ready for use position. The dome once activated, does not return to the pre-flexed position on its own accord. The radial hinges act to maintain the inverted concave position of the activated dome. Once it is inverted, the dome then in a concave configuration resides below the proximal upper edge of the housing tube sufficient to not allow re-inversion. Inversion of the dome prior to the point of use is indicative of tampering and/or premature dispension.

Fold Away Tab

As seen in FIGS. 7-10, in some embodiments there are a fold away tab or truss added to the convex dome to protect against inadvertent activation and dispension. The fold away attachment can be configured to extend from the housing tube to which the dome is attached or from the deck of the closure radial skirt. The truss has an outboard hinged attachment to the housing tube or the deck of the closure radial skirt. In some embodiments the truss also has a break-away attachment centered to the dome and truss between the outer dome and the truss. A broken break-away attachment such that it no longer connects the underside of the truss to the outer diameter of the convex dome indicates that tampering has occurred. A space is provided between the truss configuration and tube of the closure and the convex dome for ease of customer use. The truss and break-away attachment are also used to prevent the dome from premature inversion in the event a vacuum is formed on the end of the closure inside a vessel.
The inverted dome dispensing closure is activated by pressing on the truss in a manner to fold it away from the dome top. The folding motion shears the break-away attachment and is hingedly pivoted beyond the outer edge of the dome toward the radial edge of the tube. The truss is configured to have interfering engagement with the radial edge of the housing tube to prevent the truss from moving back over the dome.
A fold away truss or tab as described herein may also be employed with a frustum cone press part to protect from inadvertent activation and dispension of product and for use as an indicator of tampering.

Radial Rim

As seen in FIGS. 4-6 and 11, in some embodiments, the convex dome can be configured to have a surrounding structure around the dome, a standing radial rim, to prevent inadvertent actuation. In some embodiments the standing radial rim may be configured with one or more ports or openings to allow easier user access or to drain water after washing. In another embodiment, the standing radial rim is removable. A removable standing radial rim further comprises a pull tab to remove the rim from the housing to provide easier access to the convex dome for actuation at point of use. Removal of the radial rim before actuation by the end user is indicative of tampering. A radial rim as disclosed herein may also be employed to protect a frustum cone shaped press part from inadvertent activation and dispension of product and as an indicator of tampering.

Protective Overcap

As seen in FIGS. 12-15, some embodiments of the inverted press part dispensing closure further comprise a removable protective overcap to protect against inadvertent inversion of the convex dome or the frustum cone into a concaved position. The protective overcap surrounds the press part leaving a space between the cap and the press part such that a reasonable force against the protective overcap does not invert the dome. In some embodiments there is a hinge connecting the protective overcap to the inverted dome disclosure device allowing removal and reattachment of the cap. The hinge may connect the protective overcap to the radial closure skirt or the outer diameter of the housing. In other embodiments once the protective overcap is removed it cannot be reattached. A pull tab may be used to remove the protective overcap. The pull tab if actuated can be indicative of tampering if removed prior to the point of use.

Tamper Evident Skirt

In some embodiments as shown in FIG. 9, the closure radial skirt has a frangible tamper evident (TE) skirt that interferingly engages with the neck of an attached receiving vessel to prevent removal of the inverted press part dispensing closure. In one embodiment, there is a pull tab that when pulled breaks the TE skirt away from its engagement with the closure radial skirt. In another embodiment, the TE skirt is attached by one or more break away tabs such that application of a twisting motion to the closure radial skirt in a counter clock wise direction breaks the TE skirt away. A TE skirt that is not in interfering engagement with the receiving vessel at point of use is indicative of tampering. The closure radial skirt can be used with or without the depending tamper evident skirt band.

Mechanism of Action

The one or more ingredients stored inside the dose chamber of the housing tube are released by applying a force against the press part. In some embodiments the end user presses the press part. An embodiment of the mechanism of action is illustrated in FIGS. 16 through 20. The convex dome is pressed downwardly or inwardly until it inverts and remains in a now concaved configuration. This action directly acts on the depending septum which is attached to the end cap. The septum moves vertically downward pressing the end cap from its inactivated position within the diameter of the housing to its activated position below the distal end of the housing. This motion also causes the end cap to breach the end plate seal lining allowing the one or more ingredients inside the dose chamber of the housing tube a path way out of the tube. The pathway out of the tube is a spaced opening or port for maximum dispension about the entire area of the distal base of the housing except for the area of the distal base of the septum.
In another embodiment as illustrated in FIG. 3 (in the ready or inactivated form), the septum acts directly on the end plate seal in sufficient force to break-away the end plate seal.
In another embodiment as illustrated in FIG. 6 (in the ready or inactivated form), the septum acts directly on a septum end attachment. In turn the septum end attachment acts against the end plate seal in sufficient force to break-away the end plate seal. The one or more radial beads in the cupped end of the septum end attachment retain the broken end plate seal.
The user-actuated dispensing means of the present invention maximizes the size of the dispensing port from which one or more ingredients are dispensed. The disclosed user-actuated dispensing means provide a spaced opening at the distal end of the housing allowing one or more ingredients to exit the dose chamber and be dispensed. This created spaced opening is the dispensing port. The one or more ingredients are able to flow directly from the dose chamber of the housing into the receiving vessel. In some embodiments, the dispensing port is substantially the same in diameter as the housing. In some embodiments, the dispensing port has an area substantially the area of the distal base of the housing excluding the area of the distal base of the septum.
The inverted press part dispensing closure device is a one-piece single action delivery method to supply a dose or supply of product into a vessel to which it is attached. The design is intuitive to use and entails a one-touch easy operation by an end user. There is no twisting motion needed for dispensing and no long sleeves or other interfering extensions in the housing tube thereby avoiding or alleviating product interference with the mode of operation for dispensing.
The dispensing closure of this invention minimizes components and materials which simplifies assembly. It is constructed with fewer parts than other closures on the market. Because there are fewer components to manufacture and the components are manufactured to minimize the amount of materials used, the dispensing closures of this invention use less material to improve manufacture-ability and reduce environmental impact. Fewer components of the present invention also simplify assembly and filing.
The dose chamber is filled from the distal base of the housing with the housing in an inverted position. In some embodiments, the distal base of the housing is open or not yet sealed by an end cap, septum end attachment and/or end plate seal. The open distal end of the housing tube provides a target for easily filling the dose chamber with automated and semi-automated filling equipment of various sophistications. The relatively large target allows for automated assembly to readily locate, index, fill and sense the proper fill has been achieved.

EXAMPLES

Example 1

The POWERCAP® in one form comprises: a housing and a closure radial skirt; the housing comprising a dose chamber and a user-actuated means for dispensing one or more product and an end plate seal; the user-actuated means comprising a convex dome, septum and end cap; the convex dome further comprising a standing radial rim; the closure radial skirt further comprising a tamper evident skirt.

Example 2

Many nutrients and vitamins that can be used to create functional beverages are sensitive to the conditions most often utilized to manufacture and store such products (i.e. heat, light, water). The POWERCAP® dosing closure is a beverage technology that can protect ingredients in an enclosed chamber with a friction fit seal that can be engaged to dispense stored materials into liquid to create a functional beverage at the time of use. This experiment investigated the ability of the POWERCAP® dosing closure to retain the chemical integrity of vitamin C (ascorbic acid) and caffeine as compared to subjecting those nutrients to the conditions typical of hot fill beverage manufacturing. A standard formulation, containing known quantities of both vitamin C and caffeine, was distributed among four experimental conditions: 1) within the POWERCAP® chamber and stored without attachment to a bottle; 2) within the POWERCAP® chamber and stored fully threaded onto a standard form threaded bottle filled with water; 3) dispensed into a water volume and stored in a capped bottle; and 4) dispensed into a water volume, heated to 80° C. for 30 minutes, and stored in a capped bottle. Each of the test samples was stored in an oven at 37° C. for 30 days. At periodic interim time points, replicates were pulled from their storage conditions and evaluated by high performance liquid chromatography coupled to photodiode array and mass detectors to determine the quantity of vitamin C and caffeine retained in each. This process was repeated at the end of the 30 day experiment. Caffeine displayed strong stability under all experimental conditions. Vitamin C stability was dependant on the storage experimental conditions. Steep degradation was observed for vitamin C when mixed with water and exposed to hot fill conditions and also in extended liquid storage without hot fill temperatures. However excellent chemical stability of vitamin C was obtained when the mix was kept dry stored in POWERCAP®, off the bottle or attached to a water filled bottle. Our results demonstrate that vitamin C, a very labile nutrient easily degraded in solution, can stay stable in the dry form, even if subjected to temperature stress conditions (37° C.).
