A liner discharge structure according to the present disclosure can include: a neck collar fabricated from a liner material, wherein the neck collar encapsulates a first O-ring in the liner material; a neck fabricated from the liner material and including a first end coupled to the neck collar and in fluid communication with container liner, wherein the neck provides a passageway extending from the first end to a second end; and a discharge collar fabricated from the liner material and coupled to the second end of the neck, wherein the discharge collar encapsulates a second O-ring therein. ## Claims ### Claim 1 A liner discharge structure adapted for attachment to a container liner, the liner discharge structure comprising: a neck collar fabricated from a liner material, wherein the neck collar encapsulates a first O-ring in the liner material; a neck fabricated from the liner material and including a first end coupled to the neck collar and in fluid communication with the container liner, wherein the neck provides a passageway extending from the first end to a second end; and a discharge collar fabricated from the liner material and coupled to the second end of the neck, wherein the discharge collar encapsulates a second O-ring therein. ### Claim 2 (depends on 1) The liner discharge structure of claim 1, further comprising a liner body coupled to the neck collar, wherein a cross-sectional area of the liner body at a first position proximal to the neck collar is less than a cross-sectional area of the liner body at a second position distal to the neck collar. ### Claim 3 (depends on 1) The liner discharge structure of claim 1, wherein a shape of the neck is substantially cylindrical. ### Claim 4 (depends on 1) The liner discharge structure of claim 1, wherein the neck collar rests on a first axial end of an axial discharge spout, and wherein the discharge collar is positioned directly beneath a second axial end of the axial discharge spout. ### Claim 5 (depends on 4) The liner discharge structure of claim 4, wherein a length of the neck is less than a length of the axial discharge spout. ### Claim 6 A liner for a container, comprising: a liner body shaped and adapted to conform to an inner wall of the container and configured to contain a product, wherein the liner body is fabricated from a liner material; and a liner discharge structure attached to a liner opening in the liner body, the liner discharge structure including: a neck collar fabricated from a liner material, wherein the neck collar encapsulates a first O-ring in the liner material and fluidly isolates the first O-ring from the product within the liner body; a neck fabricated from the liner material and including a first end coupled to the neck collar and in fluid communication with the liner opening, wherein the neck provides a passageway extending from the first end to a second end; and a discharge collar fabricated from the liner material and coupled to the second end of the neck, wherein the discharge collar encapsulates a second O-ring in the liner material and fluidly isolates the second O-ring from the product within the liner body. ### Claim 7 (depends on 6) The liner of claim 6, wherein a shape of the liner body is at least partially frusto-conical. ### Claim 8 (depends on 6) The liner of claim 6, wherein a shape of the discharge structure is substantially cylindrical. ### Claim 9 (depends on 6) The liner of claim 6, wherein the neck collar rests on a first axial end of an axial discharge spout of the container, and wherein the discharge collar is positioned directly beneath a second axial end of the axial discharge spout of the container. ### Claim 10 (depends on 9) The liner of claim 9, wherein a length of the neck of the discharge structure is less than a length of the axial discharge spout of the container. ### Claim 11 (depends on 6) The liner of claim 6, wherein the neck collar physically isolates the first O-ring from the container, and wherein the discharge collar physically isolates the second O-ring from the container. ### Claim 12 A container system, comprising: a container having an axial discharge spout in fluid communication with a narrowing region thereof; and a liner positioned within the container configured to contain a product and including: a liner body shaped and adapted to conform to an inner wall of the container, wherein the liner body is fabricated from a liner material; and a liner discharge structure attached to a liner opening in the liner body, the liner discharge structure including: a neck collar fabricated from a liner material, wherein the neck collar encapsulates a first O-ring in the liner material and fluidly isolates the first O-ring from the product within the liner body; a neck fabricated from the liner material and including a first end coupled to the neck collar and in fluid communication with the liner opening, wherein the neck provides a passageway extending from the first end to a second end; and a discharge collar fabricated from the liner material and coupled to the second end of the neck, wherein the discharge collar encapsulates a second O-ring in the liner material and fluidly isolates the second O-ring from the product within the liner body. ### Claim 13 (depends on 12) The container system of claim 12, wherein a shape of the neck is substantially cylindrical. ### Claim 14 (depends on 12) The container system of claim 12, wherein the neck collar rests on a first axial end of the axial discharge spout of the container, and wherein the discharge collar is positioned directly beneath a second axial end of the axial discharge spout of the container. ### Claim 15 (depends on 14) The container system of claim 14, wherein a length of the neck is less than a length of the axial discharge spout. ### Claim 16 (depends on 12) The container system of claim 12, wherein the neck collar physically isolates the first O-ring from the container, and wherein the discharge collar physically isolates the second O-ring from the container. ### Claim 17 (depends on 12) The container system of claim 12, wherein a shape of the narrowing region of the container is substantially frusto-conical. ### Claim 18 (depends on 1) The liner discharge structure of claim 1, wherein the container liner is configured to contain a product, and wherein the first O-ring is fluidly isolated from the product within the container liner, and wherein the second O-ring is fluidly isolated from the product within the container liner. ### Claim 19 (depends on 6) The liner of claim 6, wherein the container has a discharge spout, and wherein the liner discharge structure is shaped and adapted to conform to an inner wall of the discharge spout. ### Claim 20 (depends on 12) The container system of claim 12, wherein the liner discharge structure is shaped and adapted to conform to an inner wall of the axial discharge spout.
