ABSTRACT:
A container has an inner vessel for containing liquid such as milk, water, juice or the like. An outer vessel creates a larger volume than the volume of the inner vessel, so that the inner vessel can fit inside the outer vessel. A top cap secures the inner and outer vessels in spaced relation to each other. The top cap can have an integral nipple in fluid communication with the inside of the inner vessel. In another embodiment, a vent in a top cap permits air to enter a liquid holding vessel as the liquid is removed. A filter in the vent allows the air to pass, but not the liquid, so the liquid does not spill when the container is tipped.
