Abstract

A system or method of forming a handle portion of an oral care implement and a handle portion of an oral care implement formed thereby. The method may include providing a first mold that defines a first mold cavity having a shape that corresponds to the handle portion, injecting a first material into the first mold cavity via a first injection orifice with a first hot runner sub-system, and injecting a second material into the first mold cavity via a second injection orifice with a second hot runner sub-system. The second material is injected into the first material thereby forming the handle portion, with the second material forming a core component of the handle portion and the first material forming a shell component of the handle portion that surrounds the core component.
