<p>PURPOSE:To provide plastic containers for liquid medicine to which a cracking or deformation doer not occur under high temperature sterilization and which has excellent flexibility and retains high transparency after heat sterilization, by using polypropylene with syndiotactic structure as synthetic resin in such containers made by blow molding of synthetic resin. CONSTITUTION:The plastic container 1 for liquid medicine is made by blow molding and is provided with a mouth 3 at the top of its trunk 2 and a bottom 4 and a hanging tag 5 at the lower end thereof and a stopper 6 is welded on the mouth 3. Thereupon, polypropylene substantially with syndiotactic structure is used as synthetic resin to form plastic container for liquid medicine. While said plastic container has such heat resistance as no cracking or deformation occurs due to the sterilization at the temperature e.g. above 121 deg.C, and its dripping function as plastic container for liquid medicine is very good, it is quite hygienic as no substances dissolve out from its inner wall.</p> |
