Baby Bottle Ice

This invention relates to baby bottles, and in particular to an apparatus container for keeping liquid formula cold in baby bottles.

Liquid baby formulas such as but not limited to milk mixtures and the like are generally required to be kept cold when stored in order to preserve the nutrients for health and safety reasons. Normal means of keeping the formulas cold is by storage in refrigerators. However, refrigerators are not a possible option when families are travelling either by foot or automobile. Furthermore, it is not practical to leave ice cubes in the formula since the cubes melt and thus wig dilute the formula itself. Portable ice chests are also not practical since they are often large and difficult to carry while travelling on foot through such places as shopping malls, stores and public places.

Thus, the need exists for a suitable container that can keep baby bottle formula cold to prevent spoiling while travelling.

The first objective of the present invention is to provide a portable container for keeping baby bottle formula cold.

The second object of this invention is to provide an adaptable attachment for existing baby bottles for keeping baby bottle formula cold.

The third object of this invention is to provide a container for keeping baby bottle formula cold that allows the baby to drink the formula while maintaining the formula at a nonspoiling temperature.

The fourth object of this invention is to provide a nontoxic method of keeping baby bottle formula cold.

In a preferred embodiment, an insertion container can be used with traditional type baby bottles. The container can include a longitudinal tube filled with a chilled nontoxic liquid such as frozen ice water. The tube can be inserted into a baby bottle and is supported within the bottle by a base rim which is located in the area between the top of the mouth of the bottle and the bottle cap. The base rim can include peripheral through holes for allowing baby bottle formula such as milk and the like to flow to the nipple portion of the bottle. The base rim further can include central holes for allowing the chilled drinking liquid to flow to the nipple. Optionally, the base rim can include a rubber type plug to seal the fill holes and prevent the chilled liquid in the tube from contacting the formula when the bottle is in actually being used. An alternative arrangement includes combining multiple tubes together end-to-end for using the invention with larger and longer bottles. An second alternative arrangement includes a curved insert for use with bottles that contain a center gripping hole.

Further objects and advantages of this invention will be apparent from the following detailed description of a presently preferred embodiment which is illustrated schematically in the accompanying drawings.

Before explaining the disclosed embodiment of the present invention in detail it is to be understood that the invention is not limited in its application to the details of the particular arrangement shown since the invention is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation. The components of the figures will first be discussed followed by how the components of the invention function together in a preferred embodiment.

FIG. 1 shows a side cut-away view of the baby bottle insert 100. FIG. 2a shows a top view of the invention 100 of FIG. 1 along arrow A. FIG. 2b shows a bottom view of the invention 100 of FIG. 1 along arrow B. The components of FIGS. 1, 2a and 2b will now be described. Tube 110 can be formed of clear plastic having a length "L" of approximately 5 and 1/2 inches long and walls "w" that are approximately 5/8 of an inch thick. The top portion includes a base 130 having a diameter "D" sized to the same diameter as the mouth diameter "X" of the baby bottle 400 shown in FIG. 4 which will be discussed later.

Referring back to FIGS. 1, 2a and 2b, base 130 includes a rubber type O-Ring 153 along its bottom side and a raised circular rim 135 on the top side of base 130. Base 130 further includes peripheral through holes 132, 134, 136 and 138 having a diameter of approximately 7/8 to 3/4 inch width, for allowing bottle formula 500 (shown in FIG. 5) to freely flow through. Referring to FIGS. 1, 2a and 2b, base 130 can be adhered to the outer edges of cross portion 150 by glue, cement or the like. In this position cross portion 150 forms center holes 142, 144, 146 and 148 for allowing the formula to freely flow from the bottle to the nipple portion shown in FIG. 4. The base 130 and tube 110 can be formed from well known injection molding using plastic and the like.

FIG. 3a shows a bottom view of an optional plug 300 for use with the invention 100 of FIG. 1 with prongs 342, 344, 346 and 348 surrounded by peripheral edge 312. FIG. 3b shows a top view 310 of the optional plug 300 of FIG. 3a. FIG. 3c shows a side view of the optional plug 300 of FIG. 3a with prong protrusions 342 and 348. Plug 300 can be formed from materials such as but not limited to rubber, cork and the like. Protrusions 342, 344, 346 and 348 are of such size and shape as cream as water tight seal when inserted into respective fill holes 142, 144, 146 and 148 of the base 130 of FIG. 2a. Open area 350 is cross-shaped and sized to fit cross piece 150 shown in FIG. 4.

The assembly and operation of the components of the invention depicted in FIGS. 1, 2a, 2b, 3a, 3b and 3c will now be discussed. Referring to FIG. 1, preferably a nontoxic liquid 120 such as water fills tube 110. As shown in FIG. 1, hollow tube 110 can be pre-filled with liquid such as water and then sealed at the top by being adhered to a circular cover lid 112 by glue, epoxy, cement or the like. Next, the invention insert 100 can be placed into a freezer to freeze the liquid 120 into ice in order to allow baby formula such as milk to be maintained at a temperature that avoids spoiling. Optionally, prongs 342, 344, 346, 348 and peripheral edge 312 of plug 300 shown in FIGS. 3a to 3c can be used to plug up respective holes 142, 144, 146, 148 and holes 132 to 138 of base 130 as shown in FIG. 4a. Optional plug 300 can be used in order to prevent formula in the bottle 400 from spilling during nonuse of the bottle.

Referring to FIG. 4a, insert 100 is inserted through the mouth portion 410 of the baby bottle until O-Ring 153 is aligned and abuts against the top rim 405 of mouth 410. Next, base edge portions 458 of bottle nipple 450 is aligned and abuts against the top of raised rim 135. Finally, cap 470 is positioned so that the tip portion 455 of nipple 450 passes through the hole 475 of cap 470. Cap 470 is tightened by rotating cap 470 to bottle 400 by respective matching threads 477 and 417. When tightened down, the upper inside wall 479 of cap 470 creates a water proof seal while abutted against portion 459 of nipple 450.

FIG. 4b shows the view of FIG. 4a without insert plug 300. Arrow A illustrates the flow direction of formula 500 toward nipple area 450 (not shown) when plug 300 is not being used. FIG. 5 shows an external side view of the components of FIGS. 4a and 4b assembled together.

FIG. 6 shows an alternative bottle insert 600 which can be used in larger bottles, which combines the invention depicted in FIG. 1 with an additional tube 110'. Here, Tubes 110 and 110' are connected together at 615 by techniques such as but not limited to plastic welding, glue and the like. Insert 600 can be used with different sized bottles in a similar way to that previously described in FIGS. 4a, 4b and 5.

FIG. 7 shows an alternative curved insert tube 700 for use with a modified baby bottle 800 that has a center hole 850 that is used for gripping bottle 800.

While the embodiment has been described as being used with a baby bottle, the invention can be use to cool and chill the inserts of other types of bottles such as but not limited to sport bottles, portable liquid containers and the like.
