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.

1. A flow controller for use on a container having an opening with a puncturable seal, comprising:a shipping pin;a slide member guide including a neck configured to attach to a container, and a first peripheral flange on an outer surface of the slide member guide;a slide member having an inner end and an outer end, the inner end having an open inner edge and is slidably received within the slide member guide, the outer end receiving a removable cap, the slide member having an outer surface and a second peripheral flange on the outer surface positioned to provide an annular space for insertion of the shipping pin between the first and second peripheral flanges and to prevent the inner edge of the slide member from contacting the container seal. 2. The flow controller of claim 1, wherein the neck is threadably attached to the container. 3. The flow controller of claim 1, wherein the neck is frictionally connected to the container. 4. The flow controller of claim 1, wherein the slide member is frictionally attached within the slide member guide. 5. The flow controller of claim 1, further including accordion bellows concentrically attached to the first and second peripheral flanges. 6. The flow controller of claim 5, wherein the accordion bellows form a fluid tight seal between the slide member guide and the slide member. 7. A device for controlling the flow of fluid from a container, comprising:a shipping pin;a container having an interior reservoir, a neck and a slide member guide, the neck including a seal, the slide member guide including a first peripheral flange on an outer surface of the slide member guide;a slide member having an inner end and an outer end, the inner end having an open inner edge and slideably received within the slide member guide, the outer end receiving a removable cap, the slide member including a second peripheral flange on an outer surface of the slide member to provide an annular space for insertion of the shipping pin between the first and second peripheral flanges and to prevent the inner edge of the slide member from contacting the seal. 8. The device of claim 7, further comprising means to hold the slide member within the slide member guide. 9. The flow controller of claim 7, further comprising an air vent. 10. The device of claim 9, wherein the air vent includes a vent cap releasably connected to an opening on the container. 11. The device of claim 10 wherein the vent cap is threadably connected to the aperture. 12. The device of claim 7, wherein the slide member is frictionally attached within the slide member guide. 13. The device of claim 7, further including accordion bellows attached to the first and second peripheral flanges connecting the first peripheral flange to the second peripheral flange. 14. The device of claim 13, wherein the bellows form a fluid tight seal between the first and second peripheral flanges. 15. The device of claim 7, wherein the seal is flexible. 16. The device of claim 7, wherein the seal is made of paper material. 17. The device of claim 7, wherein the seal is made of rubber material. 18. The device of claim 7 wherein the seal is made of plastic material. 19. The device of claim 7, further comprising:a puncturable air vent attached to the container;a top bracket connected to the neck within the interior reservoir of the container;a bottom bracket connected to a lower portion of the interior reservoir; anda lancing pin disposed within the interior reservoir and slidably supported by the top bracket at a top end of the lancing pin and by the bottom bracket at a bottom end of the lancing pin, the top end of the lancing pin positioned to contact the inner edge of the slide member as the slide member is urged past the container seal, and the bottom end of the lancing pin having a sharpened end positioned to allow puncturing of the air vent upon urging of the lancing pin by the slide member inner edge.
