Spray can actuator
An actuator for a spray can. The actuator includes a housing for attachment to an aerosol can covering a stem valve. A finger operating button structure is engaged with the housing for engaging the stem valve. A rotary two-way diverter valve is supported within the housing and rotatably engaged with the finger operating button structure. In a spray position/straw down, the two-way diverter valve directs spray through a first direct spray nozzle. In a second straw position/straw up, to make use of an adjustable straw, the diverter valve is rotated to engage a straw spray passage of the diverter valve in fluid communication with an adjustable rotary spray tip and engaged straw. By rotating the adjustable rotary spray tip to an aligned position, the tip substantially blocks the straw spray passage to provide a drip mode, where drops of fluid exit the straw. A flexible tip may optionally be provided on the straw to enable bending and retention of the flexible tip to a desired position.
1. An adjustable straw having an adjustable rotary spray tip with an internally threaded opening for threaded engagement with a threaded end of a rotary two-way diverter valve, fluid flow volume indicia on an outer surface of the adjustable rotary spray tip, an internal space within the adjustable rotary spray tip, and rotation of the adjustable rotary spray tip along the threaded end of the rotary two-way diverter valve increases or decreases the internal space within the adjustable rotary spray tip to correspondingly adjust the volume of fluid flow to a straw passage having a uniform internal circular diameter within and along the length of the straw passage, and having a flexible tip to enable bending of the flexible tip to a desired position.
2. An adjustable straw for a spray can actuator having fluid flow volume indicia on an outer surface of the adjustable straw, an internal space within the adjustable straw, and an internal opening for threaded engagement along a threaded end of a two-way diverter valve to increase or decrease the internal space within the adjustable straw to correspondingly adjust the volume of fluid flow to a straw passage having a uniform internal circular diameter within and along the length of the straw passage, and having a flexible tip with a corrugated external surface and an internally embedded wire to enable bending and maintaining of the flexible tip to a desired position.
3. An adjustable straw for a spray can actuator having an adjustable rotary spray tip with fluid flow volume indicia on an outer surface of the adjustable rotary spray tip, an internal space within the adjustable rotary spray tip, and an internal opening for rotating engagement along a threaded end of a two-way diverter valve to increase or decrease the internal space within the adjustable rotary spray tip to correspondingly adjust the volume of fluid flow to a straw passage having a uniform internal circular diameter within and along the length of the straw passage, and having a flexible tip with an internally embedded wire to enable bending and maintaining of the flexible tip to a desired position.
4. The adjustable straw of claim 1 , wherein the adjustable rotary spray tip with the internally threaded opening has a flow adjustment dial.
5. The adjustable straw of claim 1 , wherein the flexible tip has a corrugated external surface and an internally embedded wire to maintain the flexible tip bent in the desired position.
6. The adjustable straw of claim 4 , wherein the flow adjustment dial of the adjustable rotary spray tip includes protruding ribs to assist the user with rotation of the adjustable rotary spray tip.
