Primary Examiner-Robert B. Reeves Assistant ExaminerThomas E. Kocovsky Attorney, Agent, or Firm-Davis, Hoxie, Faithfull & Hapgood [57] ABSTRACT A variable flow rate actuator button for a pressurized aerosol dispenser having a plug which is rotatably received in a socket in the button to register different size circumferentially spaced, longitudinal feed grooves in the sidewall of the plug with a longitudinal groove in the button socket to provide variable flow rate communication between the discharge orifice of the actuator and the hollow valve stem of the pressurized aerosol dispenser.

5 Claims, 7 Drawing Figures E JENTED FEB 41975 sum 10F 2 FIGI VARIABLE FLOW RATE ACTUATOR BUTTON FOR A PRESSURIZED AEROSOL DISPENSER This invention relates to valve actuating buttons for pressurized aerosol dispensers, more specifically, it relates to a variable flow rate actuating button.

Actuator buttons are adapted to be mounted upon the hollow tubular valve stems of aerosol containers and are provided with a fluid flow passage which establishes communication between a discharge orifice in the button and the hollow valve stem of the container valve. Generally, these buttons are constructed such that the character and volume of the product discharge is substantially constant and not subject to adjustment.

Various constructions of variable flow rate actuators are known in the art. In my US. Pat. No. 3,176,888, several embodiments of two piece variable flow rate actuator buttons are disclosed. The button body includes a bore or socket into which is fitted a separate plug member having a laterally extending finger piece. The plug member is rotated relative to the button body by manually moving the finger piece. The several embodiments disclose that the plug portion includes internal passages arranged in the bottom of the plug member which are capable of being brought into selective registration with the discharge orifice of the button and with an intermediate passage in the floor of the socket leading to the hollow interior of the tubular valve stem of the container valve. The relative rotational position of the plug member with respect to the body of the button results in the selection of passage registrations for different discharge flow rates and in some embodiments sufficient relative rotation will prevent product flow to the discharge orifice. The body of the button and the plug member are each injection molded from plastic and are snap fitted to form the assembled variable flow rate actuator.

The present invention is an improvement over the several embodiments disclosed in my aforementioned patent in that the passages for effecting selective registration are arranged in the sidewall of the plug so that they are easier to mold, less subject to minor dimensional error and provide more positive control of the discharge rate since the internal passages are arranged in the sidewall rather than the bottom of the plug member where it is difficult to provide selective sealing contact between the bottom of the plug member and the floor of the socket which includes the intermediate passage. That is, the bottom of the plug must be perfectly positioned in sealing contact with the floor of the socket to ensure selective registration between the intermediate passage and the internal passage. Further, with the present invention the hollow valve stem is in direct communication with the passages for effecting selective registration and the product is not required to pass through an intermediate passage between the valve stem receiving cavity and the plug receiving socket which passage may become clogged.

It is an object of the present invention to 'provide an improved variable flow rate actuator button.

It is a further object of the present invention to provide a variable flow rate actuator button which is easier to mold than the prior art actuator buttons.

It is a further object of the present invention to provide a variable flow rate actuatorbutton which is less susceptible to clogging.

It is a further object of the present invention to provide a variable flow rate actuator button which provides more positive control of the flow rate.

Other objects, aspects and advantages of the present invention will be more apparent when the detailed description is considered in conjunction with'the drawing.

Briefly, the present invention includes a two piece molded plastic variable flow rate actuator button having a plug member rotatably mounted in a socket in the body of the button. The plug includes a plurality of circumferentially spaced feed grooves arranged in its sidewall which extend longitudinally from the bottom end of the plug along the sidewall. The feed grooves are in direct communication with the hollow.valve stem of a pressurized aerosol dispenser and are selectively placed in registration with a longitudinal groove in the socket of the body of the button by rotation of the plug member to provide communication with the discharge orifice of the button.

The present invention is illustrated with the accompanying drawing in which:

FIG. 1 is a sectional view taken along line 1-1 of FIG. 2 showing the two piece variable flow rate actuator button of the present invention;

IG. 2 is a top plan view of the two piece variable flow rate actuator button of FIG. 1;

FlG. 3 is an enlarged perspective view of a portion of the plug member showing the feed grooves;

FlG. 4 is a sectional view of a portion of the variable flow rate actuator button taken along line 4-4 in FIG. 2, showing the plug feed groove of smaller crosssectional area in registry with the longitudinal groove of the socket;

FIG. 5 is a sectional view of a portion of the variable flow rate actuator button similar to FlG. 4, showing both plug feed grooves out of registry with the longitudinal groove of the socket;

FIG. 6 is a sectional view of a portion of the variable flow rate actuator button, similar to FlG. 4, showing the plug feed groove of larger cross-sectional area in registry with the longitudinal groove of the socket; and

FIG. 7 is a sectional view of a portion of the variable flow rate actuator button taken along line 77 in FIG.

Referring to FIG. 1, the variable flow rate actuator button 10 includes a body portion 12 and a rotatable plug member 16. The body portion 12 has a central portion 18 with a valve stem receiving cavity 20 formed in its bottom 21 to receive the hollow valve stem 22 of a pressurized aerosol dispenser (not shown) and a socket 24 formed in the upper surface 26 of the body portion 12 to receive the rotatable plug member 16.

The socket 24 is axially aligned with and extends into communication with the valve stem receiving cavity 20. The socket 24 as a reduced diameter portion 27 at its lower end for snug rotatable contact between the plug member 16 and the sidewall 28 of the reduced diameter portion 27. A longitudinal passage or groove 30 is arranged in the sidewall 28 of the reduced diameter portion 27. The groove 30 may advantageously be rectangular in cross-section. The groove 30 provides communication between the reduced diameter portion 27 and the larger diameter annular chamber of the upper portion 31 of the socket 24. A discharge orifice 32 in the body portion 12 provides communication between the larger annular chamber 31 of the socket 24 and the environment.

The upper surface 26'-of the button is advantageously shaped to receive a finger to facilitate actuation. Further, the upper surface 26 advantageously includes a plurality of indicia O L H, to indicate the flow rate, off, low or high, see FIG. 2. The rotatable plug member 16 includes a lever 34 having a window or aperture 36 which exposes one of the indicia O L H, to provide a visual indication of the flow rate,

Referring also to FIG. 3, the depending plug member 16 is shaped in the form of a stepped cylinder for snapfitting into the socket 24. The plug member 16 has a reduced diameter portion 38 which is partially received within the reduced diameter portion 27 of the socket 24 and a chamfered bottom 40 to facilitate insertion into the reduced diameter portion 27 of the socket 24. A plurality of circumferentially spaced, longitudinal feed passages or grooves 42 extend inwardly from the sidewall of the reduced diameter portion 38 of the plug member 16 and communicate with-the chamfered bottom 40 of the plug member 16. The plug feed grooves 42 are of different cross-sectional areas to provide different flow rates and are circumferentially spaced relative to one another to permit selection upon rotation of the lever 34. Further, the plug feed grooves 42 are of rectangular cross-section; however, it should be understood that the plug feed grooves 42 can be of other cross-sectional shapes or less extensive longitudinally.

In operating the variable spray actuator button 10, one of the plug feed grooves 42 is brought into registry with the groove 30 in the socket 24 of the body portion 12 by rotating the plug member 16 until the indicium for the desired flow rate shows through the window 36. In FIG. 4, the plug feed groove 42 with the smaller cross-sectional area is in registry with the socket groove 30 to provide a complete product flow path between the hollow valve stem 22 and the discharge orifice 32 at a low flow rate. The indicium L is thus exposed as illustrated in FIG. 1. In FIG. 5, the plug feed grooves 42 are both out of registry with the socket groove 30. The indicium O is thus exposed by the window 36, indicating that the button 10 is off. In FIG. 6, the plug feed groove 42 having the larger cross-sectional area is in registry with the body socket groove 30. The indicium H is thus exposed by the window 36, indicating a high flow rate.

FIG. 7 shows the product flow path between the body socket groove 30, the larger annular chamber 31 of the body portion 12 and the discharge orifice 32. The plug feed groove 42 having the larger cross-sectional areais in communication with the socket groove 30.

The just described variable flow rate actuating button 10 is inexpensive to mold and requires no complicated or delicate die surfaces to mold the cooperating flow rate controlling grooves 42 and 30. The structure of the present invention does not require an aperture or passage in a transverse wall for registry with flow rate controlling passages as do the illustrated embodiments of my aforementioned patent. Consequently, the present invention is less likely to become clogged. Further, minor discrepancies in molding dimensions or the perfection of seating of the end of the plug member against the floor of the socket do not affect the flow rate. The present invention can be readily disassembled by the consumer for cleaning, if necessary, and easily reassembled.

Although described in connection with a dispenser valve having a hollow upstanding valve stem, it is apparent that the invention can be used with other forms of dispenser valves such as those having a socket for receipt of a pin or plug which depends from the button or those in which the valve and button are integral.
