Measured fluid dispenser

An adjustable measured fluid dispenser for dispensing fluid from a storage chamber of a storage container, the fluid dispenser comprising:

• a measurement chamber of a measurement container having a fillable volume;
• a cap operably couplable to the container, the cap at least partially forming a divider configured to separate the measurement chamber from the storage chamber of the container, the measurement container being fluidly sealed to the cap with at least one seal;
• at least one fluid flow passage extending through the divider and being configured to fluidly connect the measurement chamber with the storage chamber of the container;
• and
• at least one valve configured to open the at least one fluid flow passage and permit fluid flow from the storage chamber to the measurement chamber, and configured to close the at least one fluid flow passage to prevent fluid flow between the measurement chamber and the storage chamber;
• the cap having one or more axially extending guide slots that slidably receive and guide corresponding one or more radially inwardly extending guide protrusions on an inner portion of the measurement container, such that the measurement container is slidably movable axially upwardly and downwardly relative to the cap to adjust the fillable volume of the measurement chamber, and
• one or more detents arranged at an interface between the cap and measurement container that are configured to indicate discrete graduated fillable volumes of the measurement chamber.
