DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIG. 1 thereof, 
the preferred embodiment of the new and improved thermal baby bottle 
warmer embodying the principles and concepts of the present invention and 
generally designated by the reference numeral 10 will be described. 
The present invention, the thermal baby bottle warmer 10 is comprised of a 
plurality of components. Such components are individually configured and 
correlated with respect to each other so as to attain the desired 
objective. 
More specifically, the new and improved thermal baby bottle warmer system 
for maintaining a baby bottle at an elevated temperature comprises, in 
combination a thermal baby bottle warmer 14 which has a closed lower end 
16 and an open upper end 18 with an exterior side wall 20 therebetween. 
The warmer 14 preferably has an inverted frusto-conical configuration. 
Also provided is a storage chamber 24 coupled to the side wall having an 
enlarged, arcuate lower component 26 for receiving a utensil 28. The 
storage chamber is further equipped with an upper component 30 pivotally 
coupled by a hinge 32 to the side wall about a vertical axis immediately 
above the lower component for selectively allowing access to the utensil 
in the lower compartment. The storage chamber ideally has a height about 
1/2 that of the warmer 14. 
Further provided is a cylindrical interior wall 36 formed integrally with 
the thermos bottle and extending downwardly adjacent the upper end of the 
thermos bottle. Insulation material 38 is positioned between the side 
wall, interior wall, and lower end of the thermos bottle. As shown in FIG. 
3, the interior wall and side wall converge at upper ends thereof. 
A cylindrical liner 42 is provided and is adapted to receive a baby bottle 
44. The liner has a closed lower end 46 and an open upper end 48. The 
linear has a diameter less than that of the interior wall of the warmer 
14. As such, when the liner is positioned within the interior wall 36, a 
space is defined for receiving hot water 50 between the lower and side 
walls of the liner and interior wall. 
The interior wall preferably has an upper inwardly extending flange 51 on 
which an upper radially extending peripheral lip 53 of the liner rests. A 
gasket is preferably positioned between the interior wall and the liner. 
The peripheral lip of the liner is equipped with a spring-urged, V-shaped 
clip 52 which is adapted to snappily engage an annular recess formed in an 
upwardly extending annular extension 55 of the interior wall. 
A threaded lip 56 extends upwardly from the upper edge of the interior wall 
and further remains radially offset from the annular extension of the 
interior wall. The threaded lip preferably has threaded grooves formed on 
both an outer and inner surface thereof. 
A U-shaped handle 76 is provided for pivotally securing to the thermos 
bottle adjacent to its upper edge. Also provided is an interior sealing 
lid 64 with male threads 66 for selectively coupling with the interior 
threads 58 of the lid. Lastly provided is an exterior lid 70 formed as a 
dish with female threads 72 for selectively coupling with the threads of 
the lid over the interior lid. 
As described hereinabove, the thermal baby bottle system is a 
self-contained accessory for warming a baby bottle that relies on a ready 
source for electricity or hot water. The baby bottle warmer is a thermal 
unit with a removable inner liner. Like a standard thermos bottle, the 
baby bottle warmer has an inner, insulated heat-sealing lid and an outer 
plastic lid that also functions as a cup or dish. To use the baby bottle, 
hot water is added to the outer thermal unit, using the dish/lid to 
measure the correct amount. The inner liner is then inserted creating a 
seal as it comes to rests on a lip within the unit and both lids are 
screwed onto the unit. The hot water is sealed between the inner liner and 
the outer unit, and remains hot within the thermal unit for several hours. 
When a parent wishes to warm a bottle, he or she simply places it into the 
inner liner, closes the lid and waits approximately five minutes, 
depending on the temperature of the water and the desired temperature of 
the bottle. 
The outer thermal unit of the baby bottle features an attached compartment 
for a combination spoon/fork. This half-cylinder compartment is attached 
to the outer plastic wall of the unit and is also plastic. 
The thermal baby bottle provides everything necessary to prepare a baby's 
meal in a single, convenient unit. It utilizes the insulating qualities of 
a thermos bottle to keep a supply of hot water at a constant temperature 
until it is needed to heat a baby bottle. The baby bottle is a compact, 
completely portable accessory for parents. It does not require any 
external power source or access to hot water for operation and ensures 
that parents can warm a bottle for their baby whenever it is needed. 
The appealing features of the thermal baby bottle warmer is its convenient 
design, ease of use and practicality. The thermal baby bottle warmer is a 
valuable accessory for many busy parents. This device allows parents the 
freedom of traveling or pursuing leisure activities with their babies with 
the assurance that they are able to warm a bottle of formula or milk when 
they desire. In addition, since the temperature of this accessory is 
maintained for several hours, the thermal baby bottle can be used for more 
than one feeding. 
As to the manner of usage and operation of the present invention, the same 
should be apparent from the above description. Accordingly, no further 
discussion relating to the manner of usage and operation will be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to 
include variations in size, materials, shape, form, function and manner of 
operation, assembly and use, are deemed readily apparent and obvious to 
one skilled in the art, and all equivalent relationships to those 
illustrated in the drawings and described in the specification are 
intended to be encompassed by the present invention. 
Therefore, the foregoing is considered as illustrative only of the 
principles of the invention. Further, since numerous modifications and 
changes will readily occur to those skilled in the art, it is not desired 
to limit the invention to the exact construction and operation shown and 
described, and accordingly, all suitable modifications and equivalents may 
be resorted to, falling within the scope of the invention.
