Abstract
Abstract A humidifier device to prevent warping, cracking and shrinking of elements in stringed or other musical instruments subject to modification by reason of a lack of moisture in the instrument carrying case. The device comprises a small, sealed housing detachably securable to the interior of the instrument case and provides a refillable and leak-proof reservoir which feeds water or other evaporatable fluid to the top, bottom and inner peripheral side walls of an absorbent ring when the reservoir is filled to capacity; and when partially full and in any position of the carrying case water feed to the absorbent ring is maintained along at least one of the absorbent ring walls. A control ring is further provided which is rotatable about the housing to increase or decrease the evaporation rate of water from the housing ports communicating with the absorbent ring.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
In a humidifier device, the improvement comprising in combination: a relatively flat cylindrical housing having apertures along its peripheral wall and having a central, concentric depressed portion on its bottom wall; an absorbent ring mounted on said bottom wall and spaced above said depressed portion and covering said apertures, said ring being adapted to hold water or other evaporatable fluid; a retaining ring secured to said housing and abutting the top wall of said absorbent ring for maintaining said absorbent ring in position; an adjustable control ring rotably secured around said housing for regulating evaporation of said fluid through said housing apertures; and a housing cover secured to said housing and spaced above said retaining ring and having a fluid filler opening and a stopper therefor.
Claim 2
Dependent Claim
126 words
In a humidifier device, the improvement comprising in combination: a relatively flat cylindrical housing having apertures along its peripheral wall and having a central, concentric depressed portion on its bottom wall; an absorbent ring mounted on said bottom wall and spaced above said depressed portion and covering said apertures, said ring being adapted to hold water or other evaporatable fluid; a retaining ring secured to said housing and abutting the top wall of said absorbent ring for maintaining said absorbent ring in position; an adjustable control ring rotably secured around said housing for regulating evaporation of said fluid through said housing apertures; and a housing cover secured to said housing and spaced above said retaining ring and having a fluid filler opening and a stopper therefor.
Claim 3
Dependent Claim
66 words
In a humidifier device as set forth in claim 1 wherein a plurality of arcuate inner housing wall members are equally and radially spaced apart, said inner wall members each having base flanges attached to the bottom wall of said housing at the depressed portion, thereby providing compartment means for confining said absorbent ring between said inner wall members and the peripheral wall of said housing.
Claim 4
Dependent Claim
77 words
In a humidifier device as set forth in claim 2 wherein the inner periphery of said absorbent ring engages with the outer peripheries of said plurality of arcuate wall members, and wherein the outer periphery of said absorbent ring enages with the inner side of said housing peripheral wall, and wherein the bottom wall of said absorbent ring is engaged by the base flanges of said inner wall members and a bottom wall portion of said housing.
Claim 5
Dependent Claim
52 words
In a humidifier device as set forth in claim 3 wherein said apertures in the housing peripheral wall comprise a plurality of spaced ports penetrating said peripheral wall for air to enter and cause evaporation of water or other fluid to take place and impart moisture to the area surronding said device.
Claim 6
Dependent Claim
78 words
In a humidifier device as set forth in claim 4 wherein said retaining ring is affixed to the tops of said inner wall members and is provided with a plurality of radially spaced apart openings to provide passageway means for the flow of water or other fluid from the upper portion of said housing into said absorbent ring, and said housing cover being affixed peripherally to the upper edge of the housing peripheral wall in seal-tight engagement therewith.
Claim 7
Dependent Claim
32 words
In a humidifier device as set forth in claim 5 wherein said cover includes an opening for receiving water or other fluid, and further includes a cap to frictionally close said opening.
Claim 8
Dependent Claim
89 words
In a humidifier device as set forth in claim 6 wherein said adjustable control ring is freely and adjustably engageable on the outer side of the housing peripheral wall and includes a plurality of cut-outs adjacent the lower edge for exposing said plurality of spaced ports in the housing peripheral wall, said adjustable control ring being adapted to cover and uncover said plurality of spaced ports when desired by rotating said adjustable control ring in either direction to attain desired degree of humidity in the area surrounding the device.
Claim 9
Dependent Claim
52 words
In a humidifier device as set forth in claim 7 wherein said housing cover and said housing bottom wall each have a peripheral flange facing each other and adapted to engage the upper and lower peripheral edges of the said adjustable control ring therebetween for confining and retaining said adjustable control ring.
