Abstract:
1. A collapsible baby bottle for reducing air-intake during feeding operations, said collapsible baby bottle comprising: a body having a plurality of linear ridges concentrically spanning across a non-uniform circumference thereof, each of said linear ridges defining a line of weakness along which said body is selected compressed and expanded in such a manner that air is expelled outwardly from said body after being collapsed to a compressed position; a coupling threadably attached directly to a top opening of said body; a nipple removably attached directly to said coupling; a cap removably affixed directly to said coupling for protecting said nipple from undesirable foreign debris and fluids; and means for preventing formation of powder formula lumps when mixing the powder formula and water within said body so that a homogenous mixture of the powder formula and the water is obtained; wherein said powder formula lump preventing means comprises: an annular ring having an outer surface directly and statically engaged with an inner surface of said body, said ring being disposed medially between top and bottom ends of said body and further being wedged within a selected one of said linear ridges such that said ring remains at a fixed position while said body is agitated as well as when said body is compressed and expanded respectively; wherein said ring comprises: first, second, third and fourth monolithically formed linear segments having medial ends aligned with a center of said ring respectively, each of said first, second, third and fourth linear segments further having lateral ends monolithically formed with said outer surface in such a manner that said first, second, third and fourth linear segments are equidistantly spaced apart along a perimeter of said outer surface.
