A pump lid assembly for use with a container, having a rotatable pump cylinder configuration and a pump piston mechanically associated with the rotatable pump cylinder configuration such that at least a portion of the piston is deployed within the pump cylinder, thereby defining a variable pump volume. The pump piston is configured with a substantially cylindrical piston wall having an interior surface and an exterior surface such that at least a portion of the interior surface is configured for releasable attachment to the container such that when the lid is attached to the container and at least a portion of the piston circumscribes the part of the container. At least a portion of the exterior surface of the piston wall interacts with the rotatable pump cylinder configuration and the association is such that rotation of the rotatable pump cylinder configuration generates linear motion of the rotatable pump cylinder configuration. |
