The flow limiting bottle cap secures to a container having a threaded neck and allows a user to select an open or a closed position without removing the cap from a container. Additionally fluid from within a container, when poured, forms multiple separate streams in laminar flow. The cap provides a pattern of conically shaped holes for passing of fluid. Each hole has edge conditions for adjusting the flow relative to pouring. The cap opens by raising an upper portion and closes by lowering the upper portion or by rotating the upper portion to expose the holes and closing by rotating oppositely to block the holes. Knurling upon the perimeter of the upper portion aids the user. An internal seal also excludes atmospheric communication to reduce spoilage of fluids within a container. |
