Abstract
A dispenser includes a spout attached to a fluid-filled bag and a socket that is removable attached to the spout. Valves in each of the spout and socket are biased closed but are opened when the socket is latched onto the spout, thereby providing a fluid path from within the bag to the outside. Keying components are provided on each of the spout and socket in order that a fluid connection between them is made only when the key elements match. The valve within the spout extends into the bag when opened and may include a sharp bag wall piercing portion.
