In one configuration, a fitment assembly includes a fitment defining a 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, the lower neck portion depending from the upper neck, the upper neck portion including a proximal end defining a proximal opening. The lower neck portion including a distal end defining a distal opening, the tubular body defining a central bore that passes therethrough, the central bore being concentric about a central axis and passing through the proximal opening and the distal opening a flange for coupling with a container, the flange extending radially outward at a junction with the upper neck portion and the lower neck portion, wherein the lower neck portion is configured to extend into the interior of the container. ## Claims ### Claim 1 A 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 at a junction with said upper neck portion and said lower neck portion, wherein the lower neck portion is configured to extend into the interior of the container and wherein said lower neck portion includes 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. ### Claim 2 (depends on 1) The fitment assembly of claim 1, further comprising a circumferential rib that protrudes radially outward from said upper neck portion. ### Claim 3 (depends on 2) The fitment assembly of claim 2, wherein said circumferential rib is disposed at said proximal end of said upper neck portion. ### Claim 4 (depends on 1) The fitment assembly of claim 1, wherein said lower neck portion is configured for coupling with a dip tube. ### Claim 5 (depends on 1) The fitment assembly of claim 1, wherein said interior surface is configured for coupling with a dip tube. ### Claim 6 (depends on 1) The fitment assembly of claim 1, wherein said plurality of vent openings is proximate said flange. ### Claim 7 (depends on 1) The fitment assembly of claim 1, comprising: a dip tube operatively coupled to said lower neck portion of said fitment, wherein the plurality of vent openings are located between said dip tube and said flange. ### Claim 8 (depends on 7) The fitment assembly of claim 7, wherein said dip tube is operatively coupled to the inner surface of said lower neck portion. ### Claim 9 (depends on 1) The fitment assembly of claim 1, wherein said flange is coupled to a container. ### Claim 10 (depends on 9) The fitment assembly of claim 9, wherein said container is a collapsible, three-dimensional liner. ### Claim 11 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. ### Claim 12 (depends on 11) The method of claim 11, wherein said instructions further comprise coupling a headspace gas removal connector to said fitment, wherein the step of drawing said headspace gas through said vent openings and into said central passageway is performed with said headspace gas removal connector. ### Claim 13 A method for removing head space gas from a liner-based dispenser having 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 at a junction with said upper neck portion and said lower neck portion, said flange being mounted to said liner, said lower neck portion extends below said flange, said lower neck portion is configured to extend into the interior of the container and wherein said lower neck portion includes 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 are in fluid communication with a central passageway of said tubular body, the method comprising: depositing a liquid in a liner so that said liner contains said liquid and a headspace gas, the headspace gas being in contact with said vent openings of said lower neck portion of said fitment. ### Claim 14 (depends on 13) The method of claim 13, comprising drawing said headspace gas through said vent openings and into said central passageway. ### Claim 15 (depends on 14) The method of claim 14, comprising coupling a headspace gas removal connector to said fitment, wherein the step of drawing said headspace gas through said vent openings and into said central passageway is performed with said headspace gas removal connector.
