Liner discharge structure for attachment to container liner

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.

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;
