Abstract: A vented baby bottle (28) is disclosed herein and comprises a bottle (30), a nipple (32), a mounting ring (34), and a vent assembly (36). The principle advantage offered by this invention includes decreasing aeration (gas bubbles) in the bottle's fluid by establishing an air passage (168) through the mounting ring into the interior (48) of the bottle. When this air passage is used in combination with a vent assembly having a self closing vent valve (132), the system allows atmospheric air to vent into the interior of the baby bottle when a lower than atmospheric pressure is created within the bottle, thereby preventing the aeration of the fluid contained in the bottle.

Abstract: The embodiments shown provide a leak-proof spoutless toddler drinking apparatus comprised of a containing element and releasably attached led which enables the user to drink from a plurality of drinking cavities about the perimeter of the lid while preventing any leaks. The embodiments further provide an elastic collar affixed to the sidewalls of the lid and flexible pinch valve which is designed to “flex” when a sudden interior forces is placed onto it and captures any excess fluid from leaking through at least one of the plurality of drinking cavities. The ergonomic design further allows infants and toddler to grip the apparatus in one hand and drinking from any point about the perimeter of the lid while minimizing air and pressure accumulations with the apparatus.
