ABSTRACT:
A method for manufacturing a container assembly adapted to store and dispense fluid material including a collapsible flexible container adapted to be stretched from an initial nominal position and to be collapsed to dispense fluid material stored therein, and a cap member adapted to be placed in operative engagement with a neck portion of the container configured to define a dispensing flow conduit which is placed in direct flow communication with the interior of the container when the cap member is mounted in assembled position on the neck portion of the container. In the manufacture of the container assembly, the container is first stretched from its initial nominal position to expand the volume thereof, and then filled with a fluid material to be stored therein and to be dispensed therefrom while in said stretched position. The cap member is then attached to the container by connecting the cap member in operative engagement with the upper neck portion, and the container is then released from the stretched position and allowed to return to the initial nominal position whereby a quantity of fluid material stored therein commences to be emitted from a check valve at the outlet end of the dispensing flow conduit thereby to completely fill the dispensing flow conduit in the cap member with the fluid material to be dispensed.
