Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
A mechanical breakup button or actuator comprising a body with a valve stem recess therein, said recess leading to a depression on the side of said body, a post disposed in said depression, a cup shaped terminal orifice insert including a terminal orifice comprising a plurality of stepped recesses disposed in said depression such that said terminal orifice insert and said post cooperate to form an annular feed groove, said annular feed groove leading to a plurality of passageways, said passageways communicating with the innter most stepped recess of said terminal orifice which forms a swirl inducing chamber between the forward end of said post and the interior of said terminal orifice insert, said chamber communicating with said orifice, said passageways being inclined relative to the outer circumference of said swirl inducing chamber to form chordal passageways such that product is sprayed over product residue in said swirl inducing chamber to minimize potential clogging of said terminal orifice.
Claim 2
Dependent Claim
158 words
A mechanical breakup button or actuator comprising a body with a valve stem recess therein, said recess leading to a depression on the side of said body, a post disposed in said depression, a cup shaped terminal orifice insert including a terminal orifice comprising a plurality of stepped recesses disposed in said depression such that said terminal orifice insert and said post cooperate to form an annular feed groove, said annular feed groove leading to a plurality of passageways, said passageways communicating with the innter most stepped recess of said terminal orifice which forms a swirl inducing chamber between the forward end of said post and the interior of said terminal orifice insert, said chamber communicating with said orifice, said passageways being inclined relative to the outer circumference of said swirl inducing chamber to form chordal passageways such that product is sprayed over product residue in said swirl inducing chamber to minimize potential clogging of said terminal orifice.
Claim 3
Dependent Claim
53 words
The button of claim 1 wherein the outermost stepped recess and the next adjacent stepped recess cooperatively form a spray control means, said outermost stepped recess being larger than said next adjacent stepped recess such that said outermost stepped recess controls the spray pattern and said next adjacent stepped recess control spray rate.
Claim 4
Dependent Claim
33 words
The button of claim 1 wherein the interior base of said terminal orifice insert is provided with fillets to provide automatic centering of the terminal orifice with respect to said swirl inducing chamber.
Claim 5
Dependent Claim
34 words
The button of claim 1 wherein a swirl boasting chamber communicating with both said swirl inducing chamber and said terminal orifice is provided between said post and the interior of said terminal orifice insert.
Claim 6
Dependent Claim
23 words
The button in claim 1 wherein said post has a volume saver plug on its forward end extending into said swirl inducing chamber.
Claim 7
Dependent Claim
50 words
The button of claim 1 wherein said valve stem recess leads to a smaller substantially rectangular swirl chamber feed recess and said post is affixed to the wall of said rectangular recess and said rectangular recess extends below and above said post to provide feed chambers to said swirl chamber.
