Abstract
A multi flow multi venting nipple includes a teat having a flow aperture which allows for at least two different flow rates depending upon the operative radial orientation of the nipple. The nipple further includes a number of vent apertures, equal to the number of flow rates, formed by check valves extending through the nipple to reduce negative pressure during use. Each vent aperture is associated with a particular flow rate, and is radially oriented to be uppermost and vertically above the flow aperture during use at such flow rate. All vent apertures will be operable at once. The nipple further includes safety walls extending from the nipple and surrounding at least half the periphery of each check valve forming the vent apertures. The safety wall prevents unintentional and rough contact from damaging the check valves.
