Oral Care Implement With Fluid Dispensing System

A method for forming a fluid-dispensing oral care implement with a preselected oral care fluid dosage comprising:

• selecting a spacer insert from a plurality of prefabricated spacer inserts each having different configuration;
• inserting the selected spacer insert into an injection mold in an actuator button seating area of an oral care implement portion of the injection mold;
• and
• molding an oral care implement body onto the selected spacer insert.

A method for forming an oral care implement with modular fluid dispensing mechanism comprising:

• providing an elongated body defining a longitudinal axis and a handle having a proximal end and a distal end, a reservoir disposed in the handle and containing an oral care fluid, a valve fluidly coupled to the reservoir via a flow conduit, and a movable actuator button operable to dispense the oral care fluid from the reservoir through the valve via a manual pumping stroke, wherein the actuator button encloses an outwardly open pump cavity fluidly coupled to the flow conduit;
• providing a plurality of interchangeable spacer inserts each having a common mounting interface configured for insertion into the pump cavity of the handle, the spacer inserts including a first spacer insert having a first configuration and a second spacer insert having a second configuration different than the first configuration;
• inserting one of the first or second spacer inserts into the pump cavity;
• forming a trapped volume between the actuator button and the inserted one of the first or second spacer inserts which corresponds to a dosage of oral care fluid dispensed with each pumping stroke of the actuator button;
• wherein the dosage of oral care fluid dispensed with each pumping stroke is changeable via mounting the first spacer insert or second spacer insert in the pump cavity.
