Abstract
A method for efficiently producing injection molded toothbrush handles wherein two or more adjacent cavities in a mold are respectively configured to mold a first portion of a handle and a second portion of a handle, wherein upon injection molding of the first portion in a first cavity, the second portion is simultaneously injected into a second cavity into which a previously molded fist portion has been placed after its removal from the first cavity, thereby to immediately contact the previous first portion with the newly injected second portion. A third portion may also be injected into a third cavity into contact with a previously injection molded contacting first and second toothbrush handle portion. In this manner, seriatim transfer of the said portions between cavities enhances product output. The handle may include transparent or translucent portions.
