| 1992 | Invention patented by Sam C. Zambuto on July 19th, 1992. Abstract: An insert for a nursing bottle is disclosed. It is placed between the bottle and the nipple. The insert has a channel that communicates with the air passage holes in the nipple. The channel itself has air passage holes that are sized to allow air into the bottle but prevent the liquid in the bottle from exiting. This arrangement prevents the creation of a vacumn in the bottle when the liquid exits through the nipple. |
