Dispensing pouch assemblies

A nozzle assembly for use with a container having a circular opening defined by a peripheral wall and an inwardly-protruding retaining lip disposed thereon, the nozzle assembly comprising:

• a nozzle having a top end, a bottom end, and a port formed therethrough, the bottom end having a radial flange configured to he disposed within the circular opening with a peripheral upper edge portion of the radial flange engaged with a bottom surface of the retaining lip;
• a gasket encircling the nozzle and having an upper and a lower face, with a peripheral portion of the lower face configured to engage a top surface of the retaining lip;
• a retaining collar threadedly engaged in a rotational interference fit with the nozzle adapted to urge the gasket and the radial flange, respectively, against the bottom and top surfaces of the retaining lip;
• wherein the nozzle assembly is adapted to permit exit of contents disposed in the container volume only through the port.

A dispensing pouch assembly, comprising:

• a flexible and distensible pouch defining an interior volume and a circular opening into the interior volume, the circular opening having a first diameter and including an inwardly-protruding retaining lip having upper and lower surfaces;
• a nozzle defining an interior port extending from a bottom end to a top end thereof, the interior port having a second diameter, and the bottom end having a radial flange extending from the port to engage the lower surface of the retaining lip;
• a gasket encircling the nozzle and having an upper face and a lower face, with the lower face engaged with the top surface of the retaining lip;
• a retaining collar threadedly engaged in a rotational interference fit with the exterior surface of the nozzle, the retaining collar abutting the upper face of the gasket, the rotational interference fit adapted to bias the gasket downward while biasing the radial flange upward against the lower surface of the retaining lip;
• wherein the ratio of the second diameter to the first diameter is within a range of 1:6 to 1:8:
