Fa, lll-llllllllll l lllllllllll l- 4%? INVENTOR FRANK VENUS VARIABLE DISCHARGE AEROSOL SPRAY NOZZLE This invention relates to nozzles for use in dispensing fluid from small consumer-sized containers, and is particularly directed to spray-actuator devices employed for finger operation of a conventional aerosol valve or manually operated dispensing pump to effect discharge of fluid products stored in a container.
Spray nozzles of the type here concerned commonly take the form of molded plastic buttons of various shapes and sizes to permit one-finger operation of the valve stem or pump plunger of the dispensing package. The button is provided with a socket for receiving the end of the tubular stem to permit mounting of the button thereon in closing relation to the open upper end of the stem or plunger. The button is provided with a discharge orifice communicating internally with the stem-receiving socket to direct and control the discharge of fluid product from the container in a desired manner. The discharge of the product may be in the form of a fine spray, mist, droplets, foam or solid stream, depending on the nature of the product and the purpose to which it is to be applied.
For certain applications it is desirable to provide means operable by the user of the dispensing package to control the rate of discharge of fluid product on actuation of the valve or operation of the dispensing pump. Some of the means proposed for doing this have included the provision of a spray button having a small number, usually two or three, different sized discharge orifices, these being selectively brought into operation by rotating the button on the valve stem to different angularly rotated positions. Arrangements of this type are shown in U.S. Pat. Nos. 2,887,273 and 3,083,872. Another approach has been to provide a valve stem having a variably restricted entry port, illustrated for example in U.S. Pat. Nos. 3,188,008 and 3,209,960. Alternatively, arrangements for directly throttling a single fixed orifice in the button have also been suggested, as shown in US. Pat. Nos. 2,924,393 and 3.l76,888.
The present invention pertains generally to spray nozzles of the last-mentioned type but offer better control and lower cost than the arrangements heretofore proposed.
In brief, the invention comprises a spray button mounted upon a tubular duct or valve stem which communicates with a stored body of fluid product to be dispensed from a container. The button is secured to the stem by providing a socket let into an underface of the body of the button within which the outer end of the valve stem is received, fonning a close fluidtight fit while permitting relative rotation of the button on the stem. The socket of the button is closed at its inner or distal end, and a discharge passage is formed through the body of the button communicating with the socket adjacent the closed end. As more specifically described hereinafter, the socket wall is formed to provide an arcuate recess in the region surrounding the inner end of the discharge passage, and the wall of the tubular stem is likewise formed to cooperate with the button recess, whereby in different angularly related positions of the button on the stem, varying degrees of restriction to the passage of fluid from the stem to the discharge passage are produced.
The invention is illustrated by a typical embodiment shown in the accompanying drawings and described hereinafter. As will be apparent from the illustrative embodiment, the invention may take specifically different structural forms, and the appended claims are to be interpreted accordingly.
In the drawings,
FIG. I is a fragmentary view in side elevation, partly in section, of a spray button and stem combination incorporating the invention;
FIG. 2 is a fragmentary perspective view in side elevation of just the stem portion of the combination shown in FIG. 1;
FIG. 3 is a sectional view through the button portion of the combination shown in FIG. 1, taken on line 33 of that figure;
FIG. 4 is a sectional view on line 44 of FIG. 1;
FIG. 5 is a cross-sectional view similar to that of FIG. 4 but showing the parts in differently rotated relation;
FIG. 6 is a cross-sectional view similar to that of FIGS. 4 and S but showing a modified form of construction; and
FIG. 7 is a cross-sectional view in side elevation of the button member of the combination shown in FIG. 6.
A modified form of nozzle arrangement is illustrated in FIGS. 6 and 7. The configuration of button U4 and tube II2 here is essentially identical to that described above, with the exception of the means for limiting angular rotated adjustment of the members. This takes the form of a lug I30 projecting radially externally of tube 112 and a receiving, arcuate recess 136 formed in the socket wall of button 114 at a point generally diametrically opposite the radially tapered recess 124 communicating with discharge orifice 122.
It will be apparent that other modifications can be made in the structural details of the nozzle device without departing from the invention.
