Pouch assembly having a plug

A pouch assembly comprising:

• a pouch defining a cavity;
• a spout having:
• an attachment flange sealingly engaged to a pouch body, providing access to a cavity defined thereby;
• an outlet tube having a first end cooperating with the cavity, and a second end spaced apart therefrom, and an outer surface, with a plug locking surface defined in the outer surface;
• and
• a thread extending about the outer surface of the outlet tube;
• a plug having:
• a top wall having an outer rim;
• an inner axial skirt depending from the top wall in a direction opposite the top wall, the inner axial skirt including an inner surface, an outer surface, an upper end and a lower end, the inner surface defining an inner cavity;
• and
• an outer axial skirt axially spaced apart from the inner axial skirt, the outer axial skirt including an inner surface and an outer surface, an upper end proximate the top wall and a lower end spaced apart therefrom, a seal bead positioned on the inner surface of the outer axial skirt spaced apart from the upper end, the seal bead extending inwardly toward the inner axial skirt;
• wherein the inner axial skirt is releasably extendable into the outlet tube with the hermetic seal bead forming a hermetic seal against the plug locking surface of the outlet tube, a portion of the inner axial skirt being spaced apart from the outlet tube.
