Abstract
Figure 1 shows a whistle (1) with a commonly known external shape, substantially identical to the shape of the applicant company's ACME210 1 / 2 whistle. However, the outward appearance of whistle (1) is substantially very different from the known ACME210 1 / 2 whistle, and the internal structure is also very different. Whistle (1) has a polycarbonate frame or structure (2) to which an elastomer material cover or coating (3) (such as neoprene rubber) is injection molded. Structure (2) comprises upper and lower polycarbonate components assembled together before the coating (3) is applied. The portion of the internal structure (2) remains exposed in the finished whistle (1).
