Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
183 words
A sound-producing device for use with a pressurized fluid container having a valve, comprising: (a) a body coacting with the container valve and having an orifice surrounded by an annular seat, and a chamber radially outwardly of said seat adapted to receive pressurized fluid from the container when the valve is open, (b) a cap facing said seat and chamber, (c) a strap permanently interconnecting said body and cap, (d) a diaphragm extending over said seat and chamber, the margin of said diaphragm being sandwiched between said body and cap, (e) means for locking said body and cap in tight engagement so that they tightly grip said diaphragm between them and hold said diaphragm taut over said seat, and (f) means carried by at least one of said body and cap for deforming the margin of said diaphragm to aid in tightly gripping said diaphragm between said body and cap, whereby pressurized fluid which enters the chamber escapes therefrom by flowing between the tautly-held diaphragm and said seat and then out the orifice, thereby causing the diaphragm to vibrate and create a sound.
Claim 2
Dependent Claim
183 words
A sound-producing device for use with a pressurized fluid container having a valve, comprising: (a) a body coacting with the container valve and having an orifice surrounded by an annular seat, and a chamber radially outwardly of said seat adapted to receive pressurized fluid from the container when the valve is open, (b) a cap facing said seat and chamber, (c) a strap permanently interconnecting said body and cap, (d) a diaphragm extending over said seat and chamber, the margin of said diaphragm being sandwiched between said body and cap, (e) means for locking said body and cap in tight engagement so that they tightly grip said diaphragm between them and hold said diaphragm taut over said seat, and (f) means carried by at least one of said body and cap for deforming the margin of said diaphragm to aid in tightly gripping said diaphragm between said body and cap, whereby pressurized fluid which enters the chamber escapes therefrom by flowing between the tautly-held diaphragm and said seat and then out the orifice, thereby causing the diaphragm to vibrate and create a sound.
Claim 3
Dependent Claim
29 words
A sound-producing device as defined in claim 1 including a housing carrying said locking means, said housing including means for mounting the sound-producing device on a pressurized fluid container.
Claim 4
Dependent Claim
43 words
A sound-producing device as defined in claim 1 including a housing accommodating said body and cap, said locking means comprising a pair of spaced apart ribs within said housing, and each of said body and cap having a flange located between said ribs.
Claim 5
Dependent Claim
52 words
A sound-producing device as defined in claim 1 including a generally cylindrical housing having a closed end and an open end, said body and cap being accommodated within said housing near its closed end, and means at the open end of said housing for mounting said housing on a pressurized fluid container.
Claim 6
Dependent Claim
25 words
A sound-producing device as defined in claim 4 including a hole in the cylindrical wall of said housing aligned with the orifice of said body.
Claim 7
Dependent Claim
35 words
A sound-producing device as defined in claim 1 including a tubular nipple projecting from said body for snugly accommodating a stem of the pressurized container valve, the interior of said nipple communicating with said chamber.
Claim 8
Dependent Claim
13 words
A sound-producing device as defined in claim 1 wherein said strap is flexible.
Claim 9
Dependent Claim
22 words
A sound-producing device as defined in claim 1 wherein said body, cap, and strap are formed of one piece of molded plastic.
Claim 10
Dependent Claim
24 words
A sound-producing device as defined in claim 1 wherein said diaphragm is a piece of plastic tape having pressure sensitive adhesive on one face.
Claim 11
Dependent Claim
33 words
A sound-producing device as defined in claim 1 wherein said body and cap have opposed beads of different diameters for deforming the margin of said diaphragm to aid in tightly gripping said diaphragm.
Claim 12
Dependent Claim
173 words
A sound-producing device for use with a pressurized fluid container having a valve, comprising: (a) a body coacting with the container valve and having an orifice surrounded by an annular seat, and a chamber radially outwardly of said seat adapted to receive pressurized fluid from the container when the valve is open, (b) a cap facing said seat and chamber, (c) a strap permanently interconnecting said body and cap, (d) a diaphragm extending over said seat and chamber, the margin of said diaphragm being sandwiched between said body and cap, and (e) means for locking said body and cap in tight engagement so that they tightly grip said diaphragm between them and hold said diaphragm taut over said seat, said means including a pair of surfaces spaced apart a fixed distance, and said body cap being located between said surfaces, whereby pressurized fluid which enters the chamber escapes therefrom by flowing between the tautly-held diaphragm and said seat and then out the orifice, thereby causing the diaphragm to vibrate and create a sound.
Claim 13
Dependent Claim
