Description




FIELD OF THE INVENTION




The present invention relates to a disposable beverage device having a plastic bag with two compartments, one containing liquid and the other solid, and a connector having a neck member that holds the bag. More specifically, the present invention is directed to a disposable/recyclable baby bottle. The bag in this embodiment holds water in one compartment and baby formula in a second compartment.




BACKGROUND OF THE INVENTION




In places where water is safe, clean and available, infant formula is purchased in bulk and mixed with water. However, in places where water is unsafe and contaminated, using bulk solids, such as baby formula or other beverages, mixing the bulk solids with contaminated water has led to serious medical problems and often death. Further the mixing of formula for infants in bulk with available water may be simply inconvenient when at a campsite or on a trip, whether it be by automobile, train or plane. It is the object of the present invention to provide a beverage dispenser that maintains the bulk solid separate from the liquid until ready for use and to assure that a safe product is available to the user.




U.S. Pat. No. 2,885,104 discloses a bottle with a disposable cartridge. The cartridge has two compartments, one containing a powder and the other liquid. These compartments are separated by a sealing juncture that is penetrated by pulling a tab. When pulled, the tab breaks the sealing juncture, allowing the liquid to mix with the powder for dispensing.




SUMMARY OF THE INVENTION




The present invention is directed to a dispenser having a plastic bag with two compartments, one containing liquid and the other solid, and a connector having a neck member that holds the bag. The bag has a sealed seam which is easily rupturable separating the compartments. The connector may have a variety of caps for dispensing the mixed liquid and solid. More specifically, the present invention is directed to a disposable/recyclable baby bottle. The bag in this embodiment holds water in one compartment and baby formula in a second compartment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




The present invention is directed to a dispenser that includes a connector and a plastic bag that has two compartments, one for holding solid and one for holding liquid. A sealed seam which is easily rupturable separates the compartments. The solid may be selected from many beverage concentrates such as infant formula or fruit drinks and the liquid is preferably water. The dispenser preferably has a seal at the top, a plastic sheet with a tab.




Referring to

FIG. 1 and 2

, a dispenser


10


of the present invention includes a connector


12


and a plastic bag


22


having two compartments


24


and


26


. The connector


12


is a solid cylinder having a top and a bottom and the bottom being solid except having a neck shaped internally open member


14


extending there from. The connector


12


together with neck member


14


is preferably injection molded from a plastic such as polyethylene or polypropylene as a single solid piece. Other injection molding plastics may be used. On the outside circumference of connector


12


is a groove


16


. This feature of a circumferential groove


16


is important since a variety of caps, which will be disclosed in more detail hereinafter, may be attached to the dispenser


10


. The neck member


14


is internally open as well as the top of the connector


12


. The bag


22


is preferably made from a polyolefin film such as polyethylene. The bag


22


has two compartments


24


and


26


which are made in the filling operation. How the bag


22


is formed and filled is not a part of the present invention but depends on the equipment used in those operations. According to the present invention, one compartment is filled with a solid and the other compartment with a liquid. Preferably the solid is an infant formula or a beverage concentrate such as apple, fruit punch, orange, grape and other juice flavors suitable for infants. While the emphasis has been placed on infants, it is understood that the present invention has application for all ages and the beverages may be for sick and/or healthy youth and adults. The bag


22


is sealed at the bottom


23


. A seal


25


is between compartments


24


and


26


which is made of a sufficient size to keep the solid and liquid separate during packaging and distribution but is easily broken when the solid and liquid in the compartments are desired to be mixed. The top of the bag


22


is sealed creating a seal


28


that closes and seals the top the bag


22


to the neck member


14


of connector


12


. After filling bag


22


with a solid and liquid and sealing the bag


22


to the connector


12


, a plastic cover (a sheet of plastic or foil) with a tab


29


is applied to close the top of connector


12


and completes a dispenser


10


of the present invention. It is clear that in the filling operation that the solid may be in compartment


24


and the liquid in compartment


26


or vice versa. In any event, filled dispensers


10


may be filled and shipped in quantity rather than as single units.




Referring to

FIG. 3

, in this embodiment of the present invention, a cap


30


is designed for dispensing formula to an infant. The cap


30


in this embodiment has an inside wall or surface


31


that has a plurality of expansion fingers


32


. On each expansion finger


32


is a portion of a circumferential ridge


33


that snaps into the circumferential groove


16


and locks the cap


30


to the connector


12


. The baby bottle cap


30


is double walled and between the outer wall


35


and inner wall


31


are threads


36


that thread to a bottle, as will be described herein below. Also in this embodiment is a nipple


38


that seals the top of connector


12


.




The details of the baby bottle cap


30


are shown in

FIGS. 4 and 5

. In

FIG. 4

, the dispenser


10


including the connector


12


and bag


22


are shown sealed together. The top of bag


22


has a single seal or plural seals


28


sealing the bag


22


to the neck member


14


of connector


12


. The film cover and tab


29


is removed from the top of connector


12


and a nipple


38


is placed on top of connector


12


. Cap


30


is double walled and the inside wall fits over the outside surface of connector


12


. As seen in the enlarged detail of

FIG. 5

, fingers with partial circumferential ridges


33


snap into groove


16


of connector


12


and lock the cap


30


to the connector


12


. Between the outer wall


35


and inner wall


31


are threads


36


for attaching a bottle.




Referring now to

FIGS. 6 and 7

, caps


30


in these embodiments have a shaped opening other than a nipple and illustrate that caps may be used having any shaped opening. These caps


30


are single wall and do not need a bottle. For children and adults a bottle is not required. These caps


30


may be injection molded and may have a washer (not shown) inside to seal the cap


30


to the connector


12


.




In

FIG. 8

, an embodiment illustrates the complete baby dispenser with a bottle


40


.




Referring back to

FIG. 5

, in preparing a dispensing system for infant formula to places that have bad water and literacy is low, the baby bottle of the present invention is designed to maintain the purity of the solid and liquid from contamination. The cap


30


is designed so that once placed over dispenser


10


that it is difficult to remove the cap


30


. It is noted that the number of expansion fingers


32


, that portion of the inner wall


31


between parallel slots


50


, are greater in the baby bottle embodiment. For economic reasons it may be too costly to make the entire embodiment disposable. Therefore, the cap


30


is designed to be recyclable by having a tool inserted under each finger


32


to lift and move the expansion finger


32


outward sufficiently that each circumferential ridge


33


is removed from groove


16


and cap


30


may be removed from the connector


12


. The connector


12


, cap


30


and the nipple


38


may be sterilized and reused.




It is noted that the caps


30


illustrated in

FIGS. 6 and 7

can be made easily removable from the connector


12


by having less expansion fingers


32


and/or smaller ridges


33


. These removed caps


30


may then be used with another dispenser


10


.




In all embodiments, once the solid and liquid are mixed, the dispenser


10


is not to be reused and the bag


22


is disposed of after use.
