Abstract
A fluid dispenser, comprising: an actuator with a rotatable dial; a valve assembly connected to the actuator, the valve assembly being configured so as to cause fluid to be drawn from a reservoir and released from the dispenser during at least part of the time when the dial is rotated from a start position to one of a plurality of dosage positions and back to the start position, the plurality of dosage positions being at different respective angular positions of the dial; the actuator being configured to provide perceptible feedback at each of the plurality of dosage positions.
Claims35
A dispensing container, comprising:
- a casing having a dimension along a longitudinal direction;
- and
- a fluid dispenser mounted to the casing and configured so as to cause fluid to be drawn from within the casing and released towards an exterior of the dispensing container via an egress port during at least part of a time when a first element of the fluid dispenser is rotated relative to a second element of the fluid dispenser about an axis from a start position to one of a plurality of angularly spaced-apart dosage positions and back to the start position, wherein the egress port is centered about the axis;
- the first element and the second element of the fluid dispenser each having a respective outer annular portion and configured such that an axial distance between the outer annular portions remains constant throughout operation of the fluid dispenser, the outer annular portions being continuously exposed during the operation of the fluid dispenser.
A method, comprising:
- setting a dosage selector of a dispensing container to a first dosage position;
- rotating, in a first operation of the dispensing container, a first element of the dispensing container relative to a second element of the dispensing container about an axis from a start position until blocked by the dosage selector in the first dosage position and back to the start position, thereby to cause a first amount of fluid to be dispensed by the dispensing container, the first element and the second element of the dispensing container each having a respective outer annular portion and configured such that an axial distance between the outer annular portions remains constant throughout the first operation of the dispensing container, the outer annular portions being continuously exposed during the first operation of the dispensing container;
- releasing the dosage selector from the first dosage position, and setting the dosage selector to a second dosage position;
- and
- rotating, in a second operation of the dispensing container, the first element from the start position until blocked by the dosage selector in the second dosage position and back to the start position, thereby to cause a second amount of the fluid to be dispensed by the dispensing container, the second amount of the fluid being different than the first amount of the fluid, and the axial distance between the outer annular portions remains constant throughout the second operation of the dispensing container, the outer annular portions being continuously exposed during the second operation of the dispensing container.
