DETAILED DESCRIPTION

[0016] The present invention relates to a measuring and mixing pod for use with a typical baby bottle assembly. The measuring and mixing pod aids in measuring, transporting and mixing powdered infant formula with the liquid contents of a baby bottle to generate a serving of liquid infant formula for feeding a baby. The invention further relates to a baby bottle assembly including such a measuring and mixing pod, as well as a method for measuring, transporting and mixing infant formula within a baby bottle assembly including a measuring and mixing pod as disclosed herein.

[0017] Turning first to FIGS. 1, 2, and 3, an infant formula measuring and mixing pod 100 according to an embodiment of the present invention defines a unitary component made of molded plastic or some similar material. The pod 100 includes a generally cylindrical wall 102 and a curved base 104. The base 104 may include a flattened portion 114 that allows the pod 100 to stand upright when placed on a flat surface, so as not to tip and spill the contents of the pod 100 during the preparation of a bottle of infant formula. The cylindrical wall 102 may include a notched portion 108 near the top of the wall. The notched portion 108 presents a slightly smaller outer diameter than to rest of the cylindrical wall 102. As will be described in more detail below, the two different diameters allow the pod 100 to be used with baby bottle assemblies made by different manufacturers, or simply baby bottle assemblies of two different sizes having different internal dimensions.

[0018] As seen in the cross-sectional views of FIGS. 2 and 3, a push rod or post 106 rises from the base 104 of the pod 100 and extends upward above the height of the cylindrical wall 102. The cylindrical wall 102, the base 104 and the post 106 define a toroidal space or cavity 110 within the pod 100. The upper portion of the pod 100 is open so that powdered infant formula 112 may be scooped into or otherwise introduced into the cavity 110. The dimensions of the pod 100 are such that volume of the cavity 110 is substantially equal to the volume of powdered infant formula required to make a single serving of liquid formula corresponding to the size of the bottle with which the pod 100 paired. For example, the pod 100 may be intended for use with a 4 ounce baby bottle. In such case, the cavity 110 formed within the pod 100 may be sized to hold an amount of powdered infant formula necessary to make 4 ounces of liquid infant formula. Alternatively, a pod may be intended for use in an 8 ounce bottle. In this case, the cavity 110 formed within the pod 100 may be sized to hold an amount of powdered infant formula corresponding to an 8 ounce serving of liquid infant formula. Of course, the measuring and mixing pod could also be configured to work with baby bottle assemblies intended to hold other than 4 and 8 ounce serving sizes.

[0019] FIG. 4 shows an exploded perspective view of a baby bottle assembly 200 incorporating a measuring and mixing pod 100 according to an embodiment of the invention. The baby bottle assembly 200 include a bottle 202, a measuring and mixing pod 100 as described above, a nipple 230, and a fastening ring 240. The bottle 202 defines an internal space 204 for holding liquid such as water, milk, or infant formula. The bottle includes a neck portion 206 that includes external threads 208. The neck 206 terminates in an annular rim 210 that defines the mouth 212 of the bottle 202. The nipple 230 is formed of a flexible and resilient elastomeric material such as silicone rubber and includes an upper nursing portion 232 and a base portion 234. The base portion 234 includes an annular gasket portion 236. The fastening ring 240 includes internal threads 242 and an internal annular flange 244. The Nipple 230 is adapted to be inserted through the fastening ring 240 so that the annular gasket 236 at the base portion 234 of the nipple 230 engages the lower surface of the inner flange 244 of the fastening ring 230.

[0020] The measuring and mixing pod 100 may be filled with infant formula as described above, and inserted into the interior portion of the base 234 of the nipple 230. As will be described in greater detail with regard to FIGS. 5 and 6, the cylindrical wall 102 of the pod 100 forms a press-fit with an inner surface of the base 234 of the nipple 230. The inner surface of the base 234 of the nipple 230 frictionally engages the cylindrical wall 102 of the pod 100 to secure the pod 100 within the base 234 of the nipple 230 until the pod is purposefully released from the nipple 230 into the bottle 202. With the bottle 202 filled with water, the pod 100 filled with powdered formula, and the pod 110, the nipple 230, and the fastening ring 240 assembled, the fastening ring 240 may be rotatably secured to the neck 206 of the bottle 202. As the fastening ring 240 is rotated over the neck 206 of the bottle 202 the internal threads 242 formed on the inner surface of the fastening ring 240 engage the external threads 208 formed on the outer surface of the neck of the bottle 202 to secure the fastening ring 240, the nipple 230 and the pod 100 over the mouth 212 of the bottle 212. As the fastening ring 240 is tightened over the neck 206 of the bottle 202, the annular gasket 236 formed at the base 234 of the nipple 230 is compressed between the inward facing flange 244 of the fastening ring 240 and the annular rim 210 defined by the neck 206 of the bottle 202 to form a liquid tight seal between the bottle 202 and the nipple 230.

[0021] FIG. 5 shows a cross sectional view of a fully assembled baby bottle assembly 200 according to an embodiment of the invention. The bottle 202 is filled with water or some other fluid 214. The nipple 230 is secured over the mouth of the bottle 202 by the fastening ring 240, whose internal threads 242 engage the external threads 208 formed on the outer surface of the neck 206 of the bottle 202 to secure the fastening ring 240 to the bottle 202. The inner flange 244 of the fastening ring 240 compresses the annular gasket portion 236 of the nipple 230 between the internal flange 244 of the fastening ring 240 and the rim 210 of the bottle 202 to form a liquid-tight seal between the bottle 202 and the nipple 230. The pod 100 is filled with powdered infant formula 112 and is press-fit into the base portion 234 of the nipple 230. An internal surface 248 of the base portion 234 of the nipple 230 frictionally engages the outer surface of the cylindrical wall 102 of the pod 100 to hold the pod in place and to separate the liquid contents of the bottle 202 from the dry powdered contents of the pod 100. The notched portion 108 of the cylindrical wall 102 of the pod 100 presents a narrower outer diameter than the rest of the cylindrical wall 102. This narrower diameter surface allows the pod 100 to be frictionally retained within the base portion of a nipple having a smaller inner diameter surface than the nipple 230 shown in FIG. 5, adding greater versatility to the pod 100, as it can be employed with different baby bottle assemblies having slightly different dimensions. In the configuration shown in FIG. 5, the bottle assembly 200 may be stored and transported indefinitely with no adverse impact on the quality of the infant formula produced when the powdered contents 112 of the pod 100 are eventually mixed with the fluid contents 214 of the bottle 202.

[0022] An advantage of the configuration depicted in FIG. 5 is that the ingredients for preparing a bottle of liquid infant formula, namely fresh water and powdered infant formula, may be measured out in advance and stored and transported in a single container, yet kept separate from one another until it is time to feed the baby. This arrangement prevents the formula from spoiling as may be the case when the formula is mixed ahead of time.

[0023] Another significant advantage of the configuration shown in FIG. 5 is the ease with which the powdered infant formula stored in the pod 100 may be mixed with the liquid contents of the bottle 202 to prepare a serving of liquid formula for feeding an infant. The mixing process may be best understood with reference to FIGS. 6 and 7. When a caregiver determines that it is time to feed the child, he or she simply grasps the bottle assembly 200 as shown in FIG. 6. The caregiver then presses down on the nursing portion 232 of the nipple 230. As the nipple 230 is made of a flexible, resilient material, the nipple 230 compresses under the pressure of the caregiver's finger, allowing the caregiver to press down on the push rod or post 106 extending upward from the pod 100. Continued pressure from the caregiver's thumb or finger overcomes the frictional forces holding the pod 100 in place within the base portion 234 of the nipple 230, forcing the pod 100 downward into the bottle 202. Eventually the pod 100 clears the nipple 230 and is released into the liquid contents 214 of the bottle 202. The pod sinks into the liquid, releasing the powdered contents of the pod 100 into the liquid 214. As the powdered contents of the pod 100 are dispersed into the liquid, the caregiver may vigorously shake the bottle to mix the powdered infant formula with the liquid contents 214 of the bottle 202. The mixing pod 100 aids in this process by acting as an agitator, breaking up clumps of dried powder and thoroughly and evenly mixing the powdered formula within the liquid contents of the bottle. The result is fresh, smooth, evenly mixed serving of infant formula ready to be ingested by a baby.

[0024] Various embodiments of the invention have been described and illustrated; however, the description and illustrations are by way of example only. Other embodiments and implementations are possible within the scope of the invention and will be apparent to those of ordinary skill in the art. Therefore, the invention is not limited to the specific details of the representative embodiments and illustrated examples in this description. Accordingly, the invention is not to be restricted except as necessitated by the accompanying claims and their equivalents.
