Pressurized fluid-actuated sound-producing device, and method of assembling it

Abstract

A sound-producing device, for use with a pressurized fluid container, includes a body having an orifice surrounded by an annular seat, a cap facing the seat, and a diaphragm held taut over the seat, the margin of the diaphragm being tightly gripped between the body and cap. The body and cap are locked together within a housing, the housing also serving to mount the sound-producing device on a pressurized fluid container. The body and cap present annular beads of different diameters for deforming and tightly holding the margin of the diaphragm. A flexible strip permanently connects the body and cap. The parts are assembled by aligning, in side-by-side relation, a plurality of members, each comprising a body, a cap, and a connecting strap, and applying a length of adhesive-bearing flexible tape to the plurality of members, the tape adhering to one of the body and cap, preferably the cap, of each member. The line is advanced in stepwise fashion, and the tape severed sequentially between successive members near the downstream end of the line. The strap of the endmost member in the line is folded to bring its body and cap into face-to-face relation with the cut piece of tape, serving as the diaphragm, between them. The folded member is inserted into a housing wherein its body and cap are locked together so as to hold the tape or diaphragm taut over the seat.
