Fitment and fitment adapter for dispensing systems and methods for manufacturing same

A method for removing head space gas from a liner-based dispenser, comprising:

• providing a liner having a fitment assembly coupled thereto, said liner containing a liquid and a headspace gas, said headspace gas being in contact with said fitment assembly, said fitment assembly comprising a fitment for defining a rigid fluid pathway between an interior and an exterior of a container, the fitment including a tubular body having an upper neck portion and a lower neck portion, said lower neck portion depending from said upper neck portion, said upper neck portion including a proximal end defining a proximal opening, said lower neck portion including a distal end defining a distal opening, said tubular body defining a central bore that passes therethrough, said central bore being concentric about a central axis and passing through said proximal opening and said distal opening and a flange for coupling with a container, said flange extending radially outward from said tubular body portion at a junction with said upper neck portion and said lower neck portion, said tubular body defining a central passageway and the lower neck portion is configured to extend into the interior of the container and extends below said flange into said headspace gas contained in said liner, said lower neck portion including a plurality of vent openings spaced apart from one another about a circumference of the lower neck portion, the vent openings passing through a thickness of the lower neck portion in a generally radial direction from an outside surface of the lower neck portion to an inner surface of the lower neck portion for permitting fluid flow therethrough;
• and
• providing instructions on a tangible medium, said instructions comprising:
• drawing said headspace gas through said vent openings and into said central passageway.
