Abstract
Abstract Apparatus for dispensing liquid in a plurality of spray patterns includes an aerosol container having an upwardly directed valve stem mounted on its top. An overcap is fitted over the top of the aerosol container and a spray head having a plurality of nozzle outlet apertures, each corresponding to a different predetermined spray pattern is mounted to said overcap for rotational indexing motion and for rectilinear valve actuation motion. THe spray head includes a plurality of inlet ports each communicating with an associated outlet aperture. The inlet ports lie in equally spaced relation to the pivotal axis of the spray head such that when the spray head is indexed to select a desired spray pattern, one of said inlet ports is brought into alignment with the valve stem of the aerosol container. When the spray head is depressed, the valve stem and the inlet port aligned therewith are brought into fluid communication with one another and the valve stem is actuated to permit escape of the contents of the container through the desired nozzle outlet thus producing the spray pattern desired.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
328 words
Apparatus capable of dispensing liquid in a plurality of spray patterns comprising: an aerosol container having an upwardly directed valve stem mounted on the top thereof and adapted, upon actuation, to open a normally closed discharge control valve mounted on the container to effect discharge of the contents of said container through said valve stem, and a spray head mounted on said container and having a plurality of nozzle outlet apertures therein with each nozzle aperture adapted to produce a predetermined spray pattern different from the others, the spray head further having a plurality of inlet ports therein with each inlet port communicating with an associated one of said nozzle apertures, means mounting said spray head for rotational indexing movement about a pivot axis spaced from and generally parallel to said valve stem to a plurality of predetermined positions each corresponding to a desired one of the predetermined spray patterns, said inlet ports being arranged such that they lie in spaced relation on a circular arc whose center is at said pivot axis such that upon rotational movement of the spray head to any one of said predetermined positions the valve stem and that inlet port which communicates with the nozzle aperture having the desired spray pattern are brought into substantial alignment with one another, said means mounting said spray head further being arranged to provide rectilinear valve stem actuating movement parallel to said pivot axis such that when said valve stem actuating movement of the spray head is effected with the latter indexed to any one of said predetermined positions the aligned inlet port and valve stem are brought together to define a path of fluid communication therebetween with said ports and said valve stem being constructed to cooperatE with one another to depress said valve stem to effect release of the contents of said container with said contents passing along said path of fluid communication and outwardly of the nozzle aperture having the desired spray pattern.

Apparatus capable of dispensing liquid in a plurality of spray patterns comprising: an aerosol container having an upwardly directed valve stem mounted on the top thereof and adapted, upon actuation, to open a normally closed discharge control valve mounted on the container to effect discharge of the contents of said container through said valve stem, and a spray head mounted on said container and having a plurality of nozzle outlet apertures therein with each nozzle aperture adapted to produce a predetermined spray pattern different from the others, the spray head further having a plurality of inlet ports therein with each inlet port communicating with an associated one of said nozzle apertures, means mounting said spray head for rotational indexing movement about a pivot axis spaced from and generally parallel to said valve stem to a plurality of predetermined positions each corresponding to a desired one of the predetermined spray patterns, said inlet ports being arranged such that they lie in spaced relation on a circular arc whose center is at said pivot axis such that upon rotational movement of the spray head to any one of said predetermined positions the valve stem and that inlet port which communicates with the nozzle aperture having the desired spray pattern are brought into substantial alignment with one another, said means mounting said spray head further being arranged to provide rectilinear valve stem actuating movement parallel to said pivot axis such that when said valve stem actuating movement of the spray head is effected with the latter indexed to any one of said predetermined positions the aligned inlet port and valve stem are brought together to define a path of fluid communication therebetween with said ports and said valve stem being constructed to cooperatE with one another to depress said valve stem to effect release of the contents of said container with said contents passing along said path of fluid communication and outwardly of the nozzle aperture having the desired spray pattern.
Claim 3
Dependent Claim
25 words
Apparatus according to claim 1 further comprising indexing means arranged to assist in manually indexing said spray head to any one of said predetermined positions.
Claim 4
Dependent Claim
84 words
Apparatus according to claim 2 further including overcap means mounted on said container and enclosing said valve stem and the lower portion of said spray head while leaving the upper portion of the latter exposed for manual manipulation thereof, said overcap having an opening therein arranged such that the nozzle aperture having the spray pattern desired comes into alignment therewith when the spray head has been indexed to one of said plurality of predetermined positions and actuation of the valve stem has taken place.
Claim 5
Dependent Claim
