An adjustable measured fluid dispenser for dispensing a fluid from a storage chamber of a squeezable storage container via a neck of the storage container, the fluid dispenser comprising:
- a support cup with an interlocking structure configured to engage with the neck of the storage container to maintain a position of the support cup relative to the squeezable storage container, the support cup having:
- a bottom surface;
- a wall extending from the bottom surface away from the interlocking structure;
- a receiving chamber formed by the bottom surface and the wall;
- and
- a channel extending through the bottom surface of the support cup and providing a fluid passage through the bottom surface and into the receiving chamber;
- a tube configured to be fluidly coupled to the channel, such that the tube extending away from the support cup into the storage chamber when the support cup is engaged with the neck of the storage container;
- a measurement cup configured to be nested within the receiving chamber of the support cup, such that the measurement cup is rotatable within the receiving chamber;
- wherein the measurement cup includes a floor, outer walls extending from the floor, a measurement chamber defined by the floor and the outer walls, and a dividing wall separating divided fillable chambers within the measurement chamber;
- wherein each of the fillable chambers:
- includes a flow duct having a chamber fluid opening located at a height in the fillable chamber, an external fluid opening, and a flow conduit extending between and fluidly connecting the external fluid opening and the chamber fluid opening, the flow duct providing a fluid passage into the fillable chamber via the external fluid opening;
- and
- has a maximum retained volume defined by the height of a location of the chamber fluid opening of the flow duct;
- wherein the measurement cup is configured to rotate within the receiving chamber of the support cup between at least two different dispensing positions;
- wherein each of the dispensing positions is associated with one of the fillable chambers, such that the external fluid opening of the flow duct of the associated fillable chamber aligns with and fluidly connects the channel of the support cup and the associated fillable chamber via the chamber fluid opening;
- and
- wherein, when the measurement cup is rotated to a selected dispensing position of the dispensing positions, when the support cup is engaged with the neck of the storage container, and when the tube is fluidly coupled to the channel:
- a fluid flow passage is defined from the storage container to the associated fillable chamber of the selected dispensing position via the tube, the channel of the support cup, and the flow conduit of the flow duct of the associated fillable chamber;
- when a volume of the storage chamber is reduced by constriction of the squeezable storage container, the fluid from the storage chamber flows from the storage chamber to the fillable chamber via the fluid flow passage;
- and
- when a volume of the fluid in the associated fillable chamber exceeds the maximum retained volume of the associated fillable chamber and the volume of the storage chamber is no longer reduced, the fluid in the associated fillable chamber flows back through the flow passage into the storage chamber.
