TWIST CAP WITH INTEGRAL PUNCTURE MEANS ABSTRACT A captive closure with puncture means specifically designed as a replacement captive closure for liquid contai- ning containers. The novel captive closure has a puncture means which allows it to puncture any sealing membrane over the pouring orifice of a container filled with distillates and the like and allows, by rotating one of its members relative to the other, a fluid flow communication through the closure so as to allow fluids to flow from the container out. Prefer- ably the captive closure also includes a flexible pipe as part of the fluid conveying channel allowing fluid flowing from the container to be more readily poured into a destined reservoir or the like. An additional feature is a second channel, that acts as an air inflow channel, through the novel closure that is separate and apart from the fluid flow channel; the air inflow channel communicating upstream of the flow channel to the interior of the container thereby allowing air into the container during fluid outflow and thus encouraging more continuous outpouring of fluid. The air inflow channel has a novel feature that when the relative members of the closure are turned, the air flow channel is interrupted first, thereby encouraging rapid fluid flow reduction and on continuous relative turning, the fluid flow channel is then sealingly closed.
