Abstract:
A method for filling a flexible container for combined storage and administration of a liquid medicament which is particularly susceptible to turbulence, the method comprising the steps of:providing a flexible front sheet;providing a flexible rear sheet, the front and rear sheets sealed together along a common peripheral edge;heating the front and rear sheets in a first localized area to fuse together the heated portions of the adjoining surfaces, thereby forming a peelable seal extending between two sides of the common peripheral edge, the peelable seals separably joining the front and rear sheets to thereby form a liquid containing compartment and an outlet compartment;filling the liquid containing compartment with a medicament liquid;introducing a first gas into the liquid containing compartment to thereby adjust the compartment's head space;completing the seal along the container's common peripheral edge to thereby enclose the liquid medicament and first gas; andwherein said first gas is permeable through the container's front and rear sheets at a rate at least four times that of air.
