Oral care dispenser and oral care system implementing the same

An oral care dispenser comprising:

• a housing having a longitudinal axis and an internal reservoir containing a fluid;
• a collar non-rotatably coupled to the housing, the collar comprising an inner surface forming an axial passageway, a neck portion forming a first section of the axial passageway and a body portion forming a second section of the axial passageway wherein the inner surface of the collar comprising a plurality of features arranged in a circumferentially spaced-apart manner about the longitudinal axis, the neck portion formed by a plurality of segments that protrude axially from the body portion, wherein adjacent ones of the plurality of segments are separated by a gap, and wherein the plurality of features extend radially inward from the body portion;
• a drive component rotatably coupled to the collar, the drive component comprising a drive screw, a post, and one or more resilient arms extending radially outward from the post, the one or more resilient arms being curved in a second rotational direction about the longitudinal axis;
• wherein rotation of an actuator in a first rotational direction causes:
• (1) an elevator to axially advance along the drive screw in a first axial direction to dispense the fluid from a dispensing orifice;
• and (2) the one or more resilient arms to move over the plurality of features;
• and
• wherein interaction between the plurality of features and the one or more resilient arms prevents rotation of the actuator in the second rotational direction.

An oral care dispenser comprising:

• a housing having a longitudinal axis and an internal reservoir containing a fluid;
• a collar non-rotatably coupled to the housing, the collar comprising an axial passageway, a segmented annular neck portion having an inner surface forming a first section of the axial passageway, a non-segmented annular body portion forming a second section of the axial passageway, and a plurality of protuberances extending radially inward from an inner surface of a non-segmented annular body portion;
• a drive component rotatably coupled to the collar, the drive component comprising a drive screw extending from the first annular flange in a first axial direction, a post extending from the first annular flange in a second axial direction and through the axial passageway, and at least one resilient arm extending radially outward from the post in the second section of the axial passageway;
• and
• wherein rotation of an actuator in a first rotational direction causes:
• (1) an elevator to axially advance along the drive screw in the first axial direction to dispense the fluid from a dispensing orifice;
• and (2) the at least one resilient arm to move over the plurality of protuberances, the at least one resilient arm deforming when moving over each of the plurality of protuberances and resuming an original state upon passing each of the plurality of protuberances to generate an audible signal.
