A free flow formula cap comprising uniquely designed plugs to act as a passive sealing system for the nipple of a baby bottle. The plugs are retained within and at the bottom of the cap so that they align axially with the neck of the nipple when the cap is placed on the bottle. The plugs are operated from the exterior of the cap by depressing them together axially thereby pinching the nipple to create a seal between the end of the nipple and the bottle. The seal created by the plugs prevents the common problem of powder formula clogging the nipple during mixing of the same. The nipple remains sterile as one does not have to use her hands to unclog the nipple if the same were to get clogged during the mixing of the powdered formula.
