Abstract: A flow controller for a container including a slide member guide, having a first peripheral flange on an outer surface, and configured to be either integral with the container or to be attached separately to a neck of the container. The neck includes a seal. A slide member is slideably and rotatably carried within the slide member guide. The slide member includes a second peripheral flange attached to an outer surface of the slide member to provide a space for insertion of a shipping pin between the first and second peripheral flanges. The shipping pin prevents an inner edge of the slide member from contacting and puncturing the seal. The container can include a lancing pin disposed on the inside of the container and is configured to contact the slide member at a top end and actuate an air vent at the opposite end.
