A multi-component housing having a length and comprising at least a first component comprising a first plastic material, a second component comprising a second plastic material, and a third component comprising a third plastic material. The housing includes at least one tolerance-elimination element made of the second plastic material and longitudinally attached to the first component along the housing's longitudinal axis. The tolerance-elimination element has an average length extending parallel to the housing's longitudinal axis, which average length is at least ten times less than the length of the housing. The third component at least partially forms an outer surface of the housing, so that the tolerance-elimination element is at least partially overmolded by the third plastic material.

A method of forming a handle for an oral care implement. The method may include first forming a core structure out of a first hard plastic. Next, an elongated handle body may be formed out of a second hard plastic, whereby during formation the elongated handle body is made to partially surround the core structure, while leaving opposing surfaces of the core structure exposed. Finally, a grip cover may be formed out of a resilient material and positioned over at least a portion of the elongated handle body. The oral care implement handle formed by the method may include a handle having an elongated handle body and a core structure. The elongated handle body may have openings in opposing surfaces. The core structure may be partially surrounded by the elongated handle body while protruding from the openings.

An oral care implement having a multi-component handle. The oral care implement may include a head and a handle. The handle may have a front surface, a rear surface, and opposing first and second lateral surfaces. The handle may include an elongated handle body, a grip cover, and a transparent component. The elongated handle body and the grip cover may be opaque. The elongated handle body may form a portion of the front surface of the handle and the grip cover may form a portion of the rear surface of the handle. The transparent component may form a portion of each of the first and second lateral surfaces of the handle. Thus, the transparent component may form a window through the lateral surfaces of the handle.

An oral care implement having a multi-component handle. The oral care implement may include a head and a handle. The handle may include a transparent component and an opaque component. The transparent component may have a front surface, a rear surface opposite the front surface, a first lateral surface, and a second lateral surface opposite the first lateral surface. The opaque component may at least partially cover the front and rear surfaces of the transparent component while leaving the first and second lateral surfaces of the transparent component exposed. Thus, the transparent component may form a window through the lateral surfaces of the handle.
