Abstract:
1. A baby bottle for containing and releasing nourishing liquid such as milk, water, juice and the like comprising: an inner vessel for containing the liquid, the inner vessel having an open top end; an outer vessel that creates a larger volume than the volume of the inner vessel, so that the inner vessel can fit inside the outer vessel, the outer vessel also having an open top end; and a top cap that spaces the inner and outer vessels in relation to each other and can cover the open top ends of the inner and outer vessels, the top cap having a first portion that extends between the top ends of the inner and outer vessels, wherein the top cap has an opening in fluid communication with the inside of the inner vessel for controlled release of liquid contained in the inner vessel, and the opening is in an integral nipple in the top cap; wherein the first portion is made of a first weldable material, and the nipple is made of a second material different from the first weldable material, the first portion having means for securing the cap to the inner and outer vessels; and means for sealing the open top ends of the inner and outer vessels; a vent in the top cap, the vent permitting atmospheric air to enter the inner vessel as liquid is removed from the inner vessel, wherein the vent is an elongated tube having a first end secured to the top cap, and a second end that opens inside the inner vessel; and a filter in the vent; wherein the filter is substantially permeable to air, and substantially impermeable to liquid, whether wet or dry, so liquid does not spill through the vent when the baby bottle is tipped.
