Abstract
Abstract A dispensing cap for use on a pressurized aerosol-type can is characterized by a circular, pressure-receptive diaphragm flexibly spanning the upper reaches of a wall means surrounding the discharge part of the can. Liquid conduit means between an orifice centered in the diaphragm transfer pressure applied to the diaphragm and an orificed depressible valve actuator element in the discharge part. Light manual application of a compress or the like to the diaphragm results in the emission of a portion of the pressurized contents of the can and wetting of the applied article.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
In combination with an aerosol can having a centrally located valved discharge part including an orificed element depressible to operate the valve of the discharge part, a dispensing cap, comprising: continuous wall means firmly upstanding above a major annular portion of said can in encircling spaced apart relation about said discharge parT and rising thereabove; a circular, pressure-receptive, diaphragm imperforate except for a centrally located orifice, said diaphragm being disposed to fully span the upper reaches of said wall means above said discharge part, said diaphragm being flexibly intergrated with said wall means by a suspension collar rising entirely about said diaphragm periphery and forming a shallow basin, said collar being hingedly connected at its upper rim to said wall means; pressure transmitting conduit means coupling between the underside of said diaphragm in communication with said centrally located orifice and said depressible, orificed element, said conduit means providing upward passageway from said element for fluid emitted from said discharge part to the centrally located orifice of said diaphragm.
Claim 2
Dependent Claim
168 words

Claim 3
Dependent Claim
24 words
The dispensing cap of claim 1 in which said diaphragm is flexible and is concavo-convex and normally is bowed away from the discharge part.
Claim 4
Dependent Claim
37 words
The dispensing cap of claim 1 in which the pressure transmitting conduit means includes a socket on the underside of said diaphragm aligned with said centrally located orifice and is coupled with the depressible valve operating element.
Claim 5
Dependent Claim
24 words
The dispensing cap of claim 3 in which the socket comprises a stiff nipple matingly coupled with the depressible element that operates the valve.
Claim 6
Dependent Claim
27 words
The dispensing cap of claim 1 in which the suspension collar of said diaphragm is connected to the rim of said wall means by an outstanding flange.
