Abstract

This invention relates to an infant beverage dispenser (11) that carries a beverage powder and a liquid in separate compartments (15, 17) until needed. The compartments are contained in bag (13) which is separated by a seam (19) rupturable by manual squeezing of the liquid compartment (17). Once ruptured, the liquid mixes with the powder to create the beverage. An outlet is provided with nipple in order to permit dispensing of the contents.

Description

DISPOSABLE BABY BOTTLE
Cross-Reference to Related Application This invention is based on provisional application 60/141,607 filed June 30, 1999.
Technical Field
This invention relates in general to containers for dispensing a beverage, and in particular to a container that holds a powder and a liquid in separate compartments that are sealed from each other until the beverage is to be dispensed.
Background Art
Disposable baby bottles are marketed wherein the user prepares the beverage at home, then fills the bottle and dispenses it shortly after. While away from home, however this becomes more difficult. If the beverage, such as in infant formula, is placed in the bottle at home, it may spoil prior to use. While powdered infant formula is available that can be mixed water, this too can be a problem. The parent must either carry water or be able to locate purified water wherever the parent may be.
US Patent 2,885, 104 shows a bottle with a disposable cartridge. The cartridge has two compartments, one containing a powder and the other a liquid. These compartments are separated by a sealing juncture that is penetrated by pulling on a tab. When pulled, the tab breaks the sealing juncture, allowing the liquid to mix with the powder for dispensing.
Summary of Invention
In this invention, the dispenser has a flexible bag with an outlet and two compartments. One compartment is adapted to contain beverage powder while the other is adapted to contain a liquid. A seam separates the two compartments. The seam is rupturable due to manual squeezing of the compartment containing the liquid. This allows the liquid to flow into the other compartment and mix with the powder to create a beverage. A mouthpiece or nipple is attached to the bottle for allowing the beverage to be dispensed.

Description of the Preferred Embodiment Referring to Figure 1, dispenser 11 includes a bag 13 that may be of plastic or other flexible impermeable material. Bag 13 is an elongated rectangular member that is substantially flat prior to filling. Bag 13 has a powder compartment 15, which is shown in this embodiment to be on the upper end, and a water compartment 17. Compartments 15, 17 could be reversed from each other. A transverse seam 19 extends between compartments 15, 17, sealing them from each other initially. Seam 19 is located about midway along the length of dispenser 11, making compartments 15, 17 about the same size as each other, however this need not be so.
Referring to Figure 2, in this embodiment, bag 13 has a pair of sidewalls 21, 23. Seam 19 is formed by contacting interior portions of sidewalls 21, 23 with each other, then bonding sidewalls 21, 23 together at the contact line. The bonding may be by heat sealing or other known techniques. Furthermore, a perimeter seal 25 extends around the perimeter of bag 13 as shown in Figure 1. While bag 13 is shown to be two flat pieces bonded together around perimeter seal 25, it could also be formed as a tubular member, in which case perimeter seal 25 would not be necessary on the sides. Bag 13 is secured to a nipple base 27 on its upper end. The terms "upper" and
"lower" are used for convenience herein, as dispenser 11 can be oriented in any manner. Nipple base 27 has a cylindrical base wall 29 that is concentric with the longitudinal axis of nipple base 27 and bag 13. A neck 31 joins base wall 29. Neck 31 has a considerably smaller outer diameter than the outer diameter of base wall 29. Bag 13 has a mouth 33 that seals over neck 31. As shown in Figure 5, base wall 29 has a rim 35 on its upper end.
Initially, a sealing disk 37 will be adhesively secured to rim 35 to prevent any leakage from bag 13 and to discourage tampering. Sealing disk 37 has a pull tab 39 that enables disk 37 to be readily pulled from rim 35 when dispenser 11 is to be used. Figure 3 shows sealing disk 37 removed. Referring still to Figure 3, a mouthpiece or nipple 41 of conventional design is adapted be coupled to nipple base 27, which serves as an outlet for the contents of bag 13. Nipple 41 has a radially extending flange 43 on its lower end. Flange 43 has an outer portion that bears against rim 35 as shown in Figure 5.
A retainer 45 is placed over nipple 41 into engagement with nipple base 27 as shown Figures 4 and 5. Retainer 45 is a ring that has an upper wall 47 that is perpendicular to the longitudinal axis of dispenser 11. Upper wall 47 has a central portion that bears down on nipple flange 43 to form a seal with flange 43. A cylindrical inner or retention wall 51 depends downward from upper wall 47, inward from the outer diameter of upper wall 47. An outer or housing wall 53 depends downward from the periphery of upper wall 47, concentric with inner wall 51 and with the longitudinal axis of dispenser
11. A central aperture 55 is located in upper wall 47. Nipple 41 protrudes through aperture 55.
Retainer 45 preferably snaps onto nipple base 27. In the preferred embodiment, this is handled by a plurality of ribs 57, shown also in Figure 3, that extend circumferentially in a plane perpendicular to the axis of dispenser 11. Ribs 57 protrude from the interior of inner wall 51 and engage a circumferential groove 59. Groove 59 is formed on the exterior of nipple base wall 29. Ribs 57 are preferably triangular or sawtooth in shape, as well as groove 59. This allows retainer 45 to be readily pressed over nipple base 27, with ribs 57 snapping into engagement with groove 59. Once in engagement, retainer 45 is not removable from base 27. Although shown with ribs 59 on retainer 45, and groove 59 on the exterior of nipple base wall 29, the positions of ribs 57 and groove 59 could be reversed. Ribs 57 could be on base wall 29 and groove 59 on inner wall 57.
A set of internal threads 61 are located on the interior side of retainer outer wall 53. Splines 62 are located on the exterior of outer wall 53 to aid in gripping. An annular space exists between inner wall 51 and outer wall 53.
A holder or housing 63 is adapted to enclose bag 13 and engage retainer 45.
Housing 63 is a cylindrical, substantially rigid member having an open bottom 65.
External threads 67 are located on the upper end of the housing 63. The upper end inserts into the annular space between walls 51, 53, and threads 67 engage threads 61 to secure housing 63 to retainer 45.
In operation, dispenser 11 will be preferably filled at a manufacturing facility and sold with outer compartment 15 containing powder and compartment 17 containing liquid. The powder may be an infant formula, and the liquid may be purified water. Seam 19 will seal the contents of the compartments 15, 17 from each other, and sealing disk 37 will seal the contents of powder compartment 15. The package sold also preferably contains a nipple 41 and a retainer 45, shown in Figure 3, which are packaged disassembled from dispenser 11. Housing 63 is preferably sold separately and reused.
When it is desired to dispense the beverage, the user will manually squeeze liquid compartment 17 with sufficient force to cause seam 19 to break or rupture. The amount of force required to break seam 19 is far less than that required to rupture seam 25, thus seam 25 will not normally rupture due to squeezing liquid compartment 17. Once broken, the contents of compartment 15, 17 are free to commingle. The user then will flex bag 13 to cause good mixing of the components. The user pulls off sealing disk 37 with pull tab 39. The user than assembles nipple 41 and retainer 45 as shown in Figure 4. To do this, the user inserts nipple 41 through aperture 55 and presses retainer 45 downward against nipple base 27. Ribs 57 will snap into groove 59, securely locking retainer 45 and sealing with nipple flange 43. The user then may insert housing 63 over bag 13 and secure it with threads 67 to retainer 45. After use, the user unscrews housing 63 from retainer 45. The user discards dispenser 11, along with nipple 41 and retainer 45, while retaining housing 63 for later use.
The invention has significant advantages. The liquid and powder components are maintained in separate compartments. They are readily mixed simply by squeezing the liquid compartment, causing the seam to rupture. While the invention has been shown in only one of its forms, it should be apparent to those skilled in the art that it is not so limited but is susceptible to various changes without departing from the scope of invention.
