Referring now to the drawings, wherein like reference characters
designate like or corresponding parts throughout the several views,
there is shown in FIGS. 1 and 5 of the drawings a conventional
pressurized container 10 including annular shoulder 11 in the upper
end thereof which defines depression 12; upwardly extending bell
portion 13 in the center of said depression accommodates dispensing
valve 14 with stem 15 and vertical dispensing opening 16 extending
above the plane of shoulder 11. In the pressurized container thus
formed, stem 15 is normally biased upwardly as by a suitable
spring; when said stem is depressed against the pressure of said
spring, the material from container 10 flows through opening
16.
As best seen in FIG. 5 of the drawings, adapter 17 is detachably
secured to shoulder 11 of container 10. More specifically,
longitudinally extending body 18 terminates downwardly in ring 19
which defines recess 20; said ring is adapted to pass intermediate
annular shoulder 11 and bell portion 13. Male threads 21 are
provided above ring 19 exteriorly of the lower portion of body 18;
said threads terminate upwardly in proximity to collar 22
integrally formed with said body and slightly below the midpoint
thereof. Nut 23, mating with threads 21, terminates downwardly in
collar 24 of reduced diameter provided exteriorly with laterally
extending arcuate member 25 adapted to pass downwardly and inwardly

extending bore 37 in body 18 communicates upwardly with opening 38
in the top of said body.
Still referring to FIG. 5 of the drawings, sleeve 38 inserts into
the lower portion of bore 37; said sleeve terminates downwardly in
diverging conical section 40 the inner surface of which is adapted
to bear against bell portion 13 with the lower edge of said conical
section 40 normally lying in the plane of the lower edge of ring
19. As will hereinafter be described, ring 41 may be carried on
sleeve 39 whereby said sleeve may be adjustably positioned within
bore 37 to accommodate bell portion 13 of any height. Elongated
valve 42 terminates downwardly in integrally formed and diverging
conical section 43; longitudinally extending tube 44 of metallic
composition, adapted to insert into opening 16, is fixedly secured
in valve 42 with the lower end thereof extending substantially
downwardly of the lower edge of conical section 43. Spring 45,
carried on valve 42, bears against the upper end of sleeve 39 and
the lower end of collar 46 integrally formed in the approximate
medial portion of said valve, respectively. Upwardly of collar 46,
generally cylindrical section 47 of said valve is adapted to pass
through opening 38.
As best seen in FIG. 6 of the drawings, a plurality of
longitudinally spaced teeth 48 are provided in section 47
intermediate lugs 28-29, said teeth are adapted to be engaged by
teeth 35 on lever 31. The upper end of valve 42 is threaded and
preferably beveled, indicated by reference numerals 49-50,
respectively. One end of an elongated tube 51 of plastic
composition is press fitted over bevel 50 and fixedly secured
thereto by means of nut 52 adjusted to bear against the outer
surface thereof. The lower end of tube 44 is desirably provided
with a diagonally and upwardly extending vent or recess 53; bore 54
of tube 44 communicates with bore 55 of corresponding diameter in
said valve downwardly of collar 46 with coaxial bore 56 of greater
diameter communicating therewith and surfacing in the top of said
valve.
Referring now to FIGS. 1-4 of the drawings, there is shown a finger
actuated dispenser 57 detachably secured to the remote end of
elongated tube 51. More specifically, dispenser 57 includes a
generally cylindrical forward section 58 which terminates
rearwardly in male threads 59; rearwardly converging base 60
includes a longitudinally extending recess 61 in the foremost end
thereof and female threads 62 adapted to engage threads 59. Valve
63 is adjustably mounted in longitudinally extending bore 64 in
forward section 58.
Forwardly, bore 64 includes converging conical shoulder 65,
communicating bore 66 of reduced diameter, converging shoulder 67,
converging conical seat 68 paralleling shoulder 67 and rearwardly
thereof, and axial bore 69 of still further reduced diameter. Valve
63 includes integrally formed, diverging conical section 70 the
circumferential edge of which is adapted to expand against bore 64
in a tight fit when liquid under pressure is introduced into the
said bore in a manner hereinafter to be described. Forwardly
thereof, valve 63 includes a reduced diametral cylindrical section
71, and a still further reduced diametral cylindrical section 72
which terminates fowardly in converging conical face 73 adapted to
bear against seat 68.
Exteriorly, forward section 58 terminates rearwardly in
transversely spaced, U-shaped lugs 74-75 (lug 74 not shown) with
recess 76 therebetween. Forwardly extending lever arm 77 includes
trunnions 78-79 (trunnion 79 not shown) adapted to insert into lugs
74,75; essentially perpendicularly extending leg 80 of lever 77
inserts downwardly into recess 81 provided in valve 63. Spring 82
carried in recess 61 bears against the rear end of valve 63
maintaining the same in normally closed condition. Downwardly
depending connector 83, integrally formed on forward section 58,
includes male threads 84 and desirably is beveled, indicated by
reference numeral 85. The remote end of tube 51 is press fitted
onto bevel 85 and retained thereon by means of nut 86 adjusted to
bear against the outer surface of said tube. Axial bore 87 in
connector 83 communicated with bore 64 forwardly of the foremost
limit of travel of valve 63.
Disc 88 terminates forwardly in transversely extending collar 89;
female threaded portion 90, provided in the rear surface of said
disc, is adapted to mate with threads 91 in the foremost end of
section 58. Bore 92 in disc 88 communicates with bore 69 heretofore
mentioned.
Rotatable disc 93 includes a plurality of integrally formed and
rearwardly extending lugs 94 adapted to pass laterally of collar 89
with perpendicularly depending flanges 95 on each lug passing
rearwardly of said collar. As viewed in FIG. 3, a plurality of
nozzles 96-99 to provide sufficient spray patterns are press fitted
or otherwise secured in disc 93 in such a manner that each of said
nozzles is adapted to align with bore 92 in disc 88. Projections
100 on the rear surface of disc 93 insert into depressions 101 in
the foremost surface of disc 88 for such alignment.
In the embodiment of FIG. 4, a single nozzle 102 of generally
truncated conical configuration terminates rearwardly in female
threads 103 adapted to engage threads 91 on section 58 with axial
bore 104 in said nozzle communicating with bore 69.
In use, nut 23 is at least partially threaded onto threads 21 and
collar 24 inserted intermediate shoulder 11 and bell portion 13;
nut 23 is then rotated in such a direction that arcuate member 25
passes under and engages shoulder 11 of container 10, and conical
section 40 bears against bell portion 13 of said container. A
downward force on section 47 causes tube 44 to insert into opening
16 in stem 15. The user may conveniently grasp dispenser 57 with
the fingers and apply a downward force on lever 77 whereby the
material in container 10 is dispensed through a selected nozzle.
Upon releasing lever 77, valve 63 returns to normally closed
condition; upon depressing lever 31, spring 45 forces valve 42
upwardly whereby tube 44 is withdrawn from stem 15.
