ABSTRACT:
A thermoplastic pharmaceutical solution container includes a neck portion having at least one port through the neck portion. A thermoplastic port protector or closure covers the port and defines a frangible section. The closure has a length to diameter ratio providing good mechanical advantage leverage to rupture the frangible section when the closure is pushed sideways. A seal is formed with the closure by forcing a die heated above the melting point of the plastic material into the neck portion, removing a portion of the port protector and forming a depression. The frangible section is formed in the vertical side wall of the depression.
