Tapping valve

A tap assembly for reducing the infiltration of fluid from the exterior of a fluid container to the interior of a fluid container comprising;

• a tap valve further comprising a valve closure in sliding engagement across an interior surface of a hollow tap body, the tap body comprising;
• a first wall having an exterior surface and at least three apertures formed therethrough, the apertures including;
• an upper aperture providing an opening for slidably receiving at least a portion of the valve closure therein, an intermediate aperture extending to a concentric base member for allowing the passage of fluid therethrough, and a lower aperture providing a fluid outlet, and
• a multi-start male thread projecting concentrically from the exterior surface of the first wall in proximity to the upper aperture opening and configured to engage with a female thread on the valve closure,
• the valve closure further comprising;
• a plugging portion having an external surface configured to slidably fit within the tap body,
• an at least partially overlapping portion having an internal surface configured to concentrically surround the exterior surface of the first wall and extend at least partially along the length of the tap body,
• the internal surface of the overlapping portion having the female thread formed concentrically therein and configured to engage with the male thread on the exterior surface of the first wall,
• the tap assembly further comprising;
• three concentric securement pieces having a central opening formed therethrough for allowing the passage of fluid, the three concentric securement pieces including;
• the concentric base member of the tap body having an outer concentric lip portion and an inner concentric lip portion, an internal piece configured to interface with the fluid container, and having an outer concentric groove portion and an inner concentric groove portion, and
• an intermediate piece for securing the concentric base member with the internal piece, and having an outer concentric lip portion and an inner concentric groove portion,
• wherein the valve closure is configured to slidably move from an open position to a closed position as the male thread passes through the female thread and the concentric lip portions form an interference fit with the concentric groove portions thereby forming a three-point locking mechanism interlocking the three concentric securement pieces.
