This invention describes a simple hollow spike designed to pierce a bag and dispense liquid. It features a pointed tip for penetration and a hollow body for the liquid to flow through. The claims specifically describe a generally cylindrical hollow shaft with a cone-shaped tip, and an optional spigot.
Why it matters: The claimed invention is a basic mechanical device, and no specific technological advancements have emerged since 2010 to enable or significantly improve its core function. The absence of the 'ribs' feature from the claims leaves a very generic device.
