| 摘要 |
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. |

1. An apparatus for venting a baby bottle, comprising:
a bottle forming a hollow container with an interior volume suitable for holding a liquid, said bottle having a single opening into said interior volume, said single opening located at a top portion, said single opening further having an interior diameter; a nipple; a mounting ring having a body portion and a flanged top, and an opening in said flanged top sized to receive and retain said nipple; a vent assembly further comprising:
a vent ring having a body, a flange attached to said body, a vent hole and a liquid passage passing through said body; anda vent valve;wherein when said body of said vent ring is fitted into said bottle, and when said flange is positioned adjacent to said top portion, an air passage is created allowing atmospheric air to pass diametrically along said flange into said vent hole, said air passage ending adjacent said vent valve; wherein in a first position said vent valve is closed blocking said air passage; wherein in a second position, said vent valve is opened allowing atmospheric air located in said air passage to enter said interior volume of said bottle; and wherein said vent valve is positioned from said first position to said second position by creating a lower than atmospheric pressure in said interior volume of the bottle. |
