Abstract
A method of filling, sealing and sterilizing a pharmaceutical package including a polypropylene bottle containing a balanced salt solution includes the steps of filling each bottle to maximum capacity to exclude residual air, the introduction of a silicone rubber gasket into the bottle cap to absorb pressure and prevent leakage during a steam sterilization procedure, and the enclosure of the filled bottles in a blister pack before steam sterilizing. The blister packs have Tyvek.TM. lids and are placed blister-side-up during the sterilization process to eliminate deformation of the blister during sterilization. Maximum filling of the bottle with liquid and the substantial elimination of air prevents dimpling of the bottle.
