System and Method for Forming an Oral Care Implement

A system for forming a handle portion of an oral care implement, the system comprising:

• a first mold defining a first mold cavity having a first mold cavity axis, at least a portion of the first mold cavity having a shape that corresponds to the handle portion of the oral care implement;
• a first injection orifice formed into the first mold and providing a first passageway directly into the first mold cavity;
• a second injection orifice formed into the first mold and providing a second passageway directly into the first mold cavity, the second injection orifice spaced apart from the first injection orifice;
• a first hot runner sub-system fluidly coupled to the first injection orifice;
• a second hot runner sub-system fluidly coupled to the second injection orifice;
• and
• wherein the system is configured to dispense the first material into the first mold cavity via the first injection orifice with the first hot runner sub-system, and after passage of a predetermined period of time, to subsequently dispense the second material into the first mold cavity via the second injection orifice with the second hot runner sub-system, the second material being injected into the first material to displace the first material, thereby forming the handle portion of the oral care implement such that the second material forms a core component of the handle portion and the first material forms a shell component of the handle portion that surrounds the core component.
