CA 2509587

A package for dispensing a viscous product includes a container having an end wall, a resilient sidewall, and a finish to which a skirt of a dispensing closure is attached. The closure includes a base wall having a discharge opening and an adjacent vent opening. A valve body extends from the base wall and includes a through passage aligned with the vent opening. A check valve is disposed within the valve body, and a tube includes a first end attached to the valve body and extends from the fixed end toward the end wall of the container, and terminates in an open second end adjacent to the end wall of the container. The check valve functions when the container is squeezed to prevent air passage out the vent opening, and functions when the container is released to permit air passage through the vent opening and the tube.
