Abstract
Abstract A dispensing valve assembly for dispensing a product from a pressurized container. The dispensing valve assembly includes a nozzle and a valve stem which are mounted to permit misalignment of the valve stem axis and the nozzle axis. The nozzle and valve stem include a first valve means at the terminal end of the nozzle and a second valve means spaced from the other end. The valve means are seated to prevent product flow through the nozzle when the stem and nozzle are in alignment. Upon the application of a lateral force to the nozzle, the axes are out of alignment and the valve means unseated so that the product is dispensed through the nozzle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
A dispensing valve assembly for dispensing the contents from a pressurized container, said dispensing valve comprising a tubular nozzle made from a resilient material, said nozzle having an axial bore including a first valve seat means formed adjacent one end adapted to be attached to the container and a second valve seat means at the opposite free end defining a discharge end, a rigid valve stem coaxially disposed in said bore and having a fiRst valve surface seatable on said first valve seat means and a second valve surface seatable on said second valve seat means, said valve stem intermediate said first and second valve surfaces being of lesser diameter than the diameter of the bore along the major portion of the length thereof to define a product dispensing passage, means mounting said valve stem and said nozzle on said container below said second valve seat means, said mounting means restraining said nozzle and said valve stem against relative longitudinal movement and allowing relative tilting movement between a position wherein said surfaces are seated on said respective valve seats and a position wherein said first and second valve seats are unseated so that the container contents may be dispensed through said product dispensing passage and the terminal end of said nozzle.
Claim 2
Dependent Claim
211 words
A dispensing valve assembly for dispensing the contents from a pressurized container, said dispensing valve comprising a tubular nozzle made from a resilient material, said nozzle having an axial bore including a first valve seat means formed adjacent one end adapted to be attached to the container and a second valve seat means at the opposite free end defining a discharge end, a rigid valve stem coaxially disposed in said bore and having a fiRst valve surface seatable on said first valve seat means and a second valve surface seatable on said second valve seat means, said valve stem intermediate said first and second valve surfaces being of lesser diameter than the diameter of the bore along the major portion of the length thereof to define a product dispensing passage, means mounting said valve stem and said nozzle on said container below said second valve seat means, said mounting means restraining said nozzle and said valve stem against relative longitudinal movement and allowing relative tilting movement between a position wherein said surfaces are seated on said respective valve seats and a position wherein said first and second valve seats are unseated so that the container contents may be dispensed through said product dispensing passage and the terminal end of said nozzle.
Claim 3
Dependent Claim
76 words
The invention as defined in claim 1 wherein said mounting means includes a base formed integral with said valve stem, said base having a plurality of angularly and radially spaced ports located outboard from said first valve surface means and being sealed by a surface on said nozzle when said longitudinal axes are aligned and providing communication between the interior of the container and said nozzle bore when said lateral force is applied to said nozzle.
Claim 4
Dependent Claim
24 words
The invention as defined in claim 2 wherein said valve stem base and said nozzle are mounted for rocking movement relative to each other.
Claim 5
Dependent Claim
34 words
The invention as defined in claim 1 wherein said valve stem contiguous to said second valve surface means is formed with a length having a diameter substantially equal to the diameter of said bore.
Claim 6
Dependent Claim
28 words
The invention as defined in claim 4 wherein said second valve seat comprises a conical surface and said second valve surface is formed complementary to said conical surface.
Claim 7
Dependent Claim
25 words
The invention as defined in claim 3 wherein said nozzle is mounted on said container and includes means supporting said base against vertical axial movement.
Claim 8
Dependent Claim
28 words
The invention as defined in claim 3 wherein said valve stem base is mounted on said container and includes means for supporting said nozzle against vertical axial movement.
