with the trigger 32 and an inner cylindrical end 46 which is
received in a cylindrical opening 48 in the body 14 for the
purpose of varying the volume in a pumping chamber defined in
the opening 48.
~; 15 The trig~er 32, the qpring assembly 40, the piston 4~ and
the cylindrical opening 48 form and define primary components
of a pumping mechanism 49.
:~ ~ A valve:intake stem S0 i~ received into the bottom of the
cylindrical base:26 and ha~ a dip tube 52 releasably fixed
: 20 thereto and depending therefrom for insertion into the bottle
12.
:: ~ A safe and child resistant sprayer/bottle connection is
: provided and ~includes locking tabs 53 with lug receiving
openings 54 ~formed: in the cylindrical ~ide wall of the
2:5 cylindrical base~26:and locking lug~ on the bottle nec~ 30 and
locked in pl~ce~by the locking ring 28.
: When the moldet sprayer body i~ removed from a mold, the
; iocking ring 28, connected to the cylindrical base 26 of the
body 14 by ix links, points, fillets or webs 57 which are
30 nece~ ary for~molding the locking ring 28 together with the
body 14, i~ broken away from the cylîndrical ba~e 26 by
:~ breaking the fillets 57 and moved upwardly on the base 26.
~: During assembly of the part3 of the trigger sprayer 10, the
: locking ring 28~is moved downwardly over the cylindrical base
35 26.
A nozzle assembly 58 iq provited and includes a rotAtable

16 extending from a cylindrical por~ion 6 of the body 14 and
include an annular band 66 for holding the nozzle cap 60.
Three different positio~s of the nozzle cap 60, a S~O~
position, a SPRAY po~ition, and a STREAM position are provided.
When the nozzle assembly 58 is mounted to the body 14, a
mounting block 67 of the piece 20 i9 snap fittingly received
through an opening 68 in the top portion 22. At the ~ame time,
fork arms 69 of the piece 20 extend through notche~ 70 in the
top portion 22 and/or notches 71 in the top wall of the cap 60
10 between one of two flexible locking leg~ or prongs 72 and the
cylindrical portion 64 for securing the nozzle cap 60 in it3
STO~ position, thereby ensuring a tamper proof and child
resi~tant locking of the trigger sprayer nozzle as~embly 58 to
the body 14~
The nozzle assembly 58 i3 mounted on the dis~harge end 18
of ~rigger sprayer lO, a~ described above. The top portion 22
of the body 14 extend~ rearwardly to a rear end 73 of the hand
gripping formation 24 and the~ ~lants forwardly and downwardly
from the rear end 73 to the cylindrical base 26.
The ~ix contact fillets or webs 57 are uniformly
distributed around the lower end of the cylindrical base 26 and
: ar~ initially integral with the locking ring 28. During the
molding proce~, the contact fillets or webs 57 are broken and
~he locking ri~g 28 is moved upwardly relative to the
25 cylindrieal ba~e 26. Later, when ~he locXing ring 28 i~ moved
downwardly on the ba~e 26, an annular groove 74 within the
~: locking ring 28 ~nap-fittingly mates with an annular rib 75 on
th~ ba~e 26. Th~ upper po~ition of the loc~ing ring 28 is the
pr~ application-to-a-bottle positio~ and the loc~ing ri~g 28 is
: 39 held in this po~ition by fri~tional engagement of the inner
:~ wall of the locking ring 28 with the rib ~egments 76 provided
on th~ outer cylindrical wall of the cylindrical base 26. The
uppe~, partially annular rib segment~ 76 on the outer
cylindrical wall of the cylindrical base 26 loca~e a~d to some
35 exte~t limit upward movement of the locki~g ring 28.
A~ shown in FIG. 3, molded within the cyli~drical base 26
to a top wall 314 of the cylindrical base 26 i~ a ~mall
diameter ~eal ring 316. The seal ring 316 is de3igned to seal

against the inner diameter of the bottle neck 30. The seal
ring 316 has a bevelled end 318 at its lower side to facilitate
insertion of the bottle neck 30 into the base 26 and around the
seal ring 316.
Within the inner area o~ seal ring 316 i~ an opening 320,
having a shape according to the shape of the intak~ stem 50
which i~ generally oval in cross-section. The intake stem 50
is pre~s-fitted into the opening 320 until ridge~ 322 on the
intake stem 50 snap into mating mounting grooves on the inner
10 surface of the wall of the ope~ing 320. In this way, an air
tight seal is provided. The diptube 52 i8 releasably fixed in
the center of the intake stem 50. The length of the diptube 52
depends on the size o~ the bottle 12. However, it i~
recommended that the diptube 52 should extend to the bottom of
15 the bottle 12 but shouldn't touch it.
The cylindrical opening 48 is located inside the body 14
of the trigger sprayer 1~. The piston cylindrical end 46 ~its
tightly into the cyli~drical opening 48 to create a pumping
chamber 324 having a variable volume between a fixed back wall
20 326 of the cylindrical opening 48 and a rearwardly ~acing w~ll
328 of the piYton cylindrical end 46. The fix~d wall 326 of
: th~ pumping chamber 324 has an inlet flap valv~ 330 ~ituated in
~:~ the lower part thereof and an opening 332 in th~ upper part
thereof. An orifice 334 through a wall of the intake stem 50
~5 is located to mate or register with the inlet flap valYe 330
and to e~tablish an inlet passageway. The inlet pa~3ageway i~
~: provided by the ho~low diptube 52, the intak~ ~tem 50 and the
;~; orifice 334.
The opening 332 is located to mate or regi~ter with an
~: 30 outlet flap valve 33~ on the top sid~ of intake ~tem 50. Inlet
: flap valve 330 and outlet flap valve 336 control the ~luid flow
into a~d-out of pumping chamber 324.

bushing 16 includes a cylindrical extension 702 having an inner
cylindrical cavity 704. The cylindrical extension has a first
slot 706 through the cylindrical wall thereof which is a so-
called tangential 810t for directing liquid tangentially into
5 the cylindrical cavity 704 and has a second, so-called radial,
slot 708 for directing liquid radially into the cylindrical
cavity 704.
The cylindrical extension 702 is small-in-diameter and is
located coaxially with an outer aylinder 710 having a larger
10 diameter. In the embodiment ~hown in FIG. 4, the smaller
: cylindrical extension 702 extends outwardly from a web 712 of
: material which fixes the cylindrical extension 702 in the
po~ition shown ant defines between, an inner wall 714 of the
outer cylinder 710, two waterways 720 and 722 which communlcate
- : 15 liquid to be sprayed in a SP~AY or ST~EAM to the tangential
slot 706 or to the radial slot 708.
Also, it will be apparent from FIG. 4 that the top of the
body 14 between the slot~ 70 has a tab extension 726 which
extends partially into a locating slot 728 in the back
20 underside of a top side wall 730 of the nozzle cap 60 as shown
in:FIG. 5.
,~
With reference to FIG. 5, ~t will be seen that the nozzle
cap 60 ha~ a generally square configuration with the top side
wa}l 730 having S~OP indicating indicia. A left side wall 734
: 25 has 8P~AY indicating indicia thereon and a right side wall 738
: which ha~ SIREAN~indicating indicia.
Also, the~nozz:le cap 60 has a bottom wall 742, as shown in
FIG. 5.
: Within the~envelope of the forward portions of the walls
30 730, 734, 738~ and 742 and extending rearwardly from a front
wall 744 of~th-~nozzle cap 60 is a fir~t outer cylinder 746
which- is adapted~to receive therein the outer:cylinder 710 of
the noae bushing~l6. Then, also extending rearwardly from the
: : front wall 744 within the outer cylinder 746 is a smaller-in-
35 diameter cylinder 748 having a slot 750 extending radially
therethrough:which is adapted, upon selective rotation of the
nozzle cap 60, to mate with either the tangAential ~lot 706 or
the radial 810t 708 in the cylindrical extension 7G2. The
-substitute sheet-
~:'
:~:
~2~ 30 8~ IPEA~J~ 19 AuGl993
smaller-in-diameter cylinder 748 is adapted to be received over
the cylindrical extension 702.
In a manner which is ~onventional in the art, when the
nozzle cap 60 is rotated counterclockwise 90~ from the ~TOP
5 position to the SPRAY position, liquid in the waterway 720 will
pass through the slot 750 and throuyh the mating 910t 706 into
the cylindrical cavity 704 and in a swirl forwardly to an
outlet orifice 752 in the front wall 744 of the nozzle cap 60.
In a similax manner, when the nozzle cap 60 i~ rotated
10 clockwi~e 90 from the STOP position to the S~RE~M po~ition,
the slot 750 in the wall of the cylinder 748 will mate or
register with the radial slot 708 whereby liquid can flow from
the waterway 722 through the siot 750 and through the ~lot 708
radially into the cylindrical ~avity 704 and then axially
15 forwardly and out of the orifice 752.
In this way, in a manner similar to previously proposed
nozzle as~emblies, liquid can be directed through the waterways
720 and 722 to selectively aligned, axially extendîng or
: radially extending, slots for communicating liquid in a ~wirl
20 or in an axial path to the orifice 752 for effecting a desired
discharge of liquid in either a coni~al spray or mist-like
di~charge or in a substantially axial STREAM type dischar~e.
A}so, it will be understood that different formations can
be utilized ~or effe¢ting the mating of one or more tangential
25 slots through a radial slot to a waterway or one or more radial
slots to a radial or longitudinal 310~ and thence to a
waterway, as di~clo~ed in the Quinn et al U.S~ Patent No.
4,234,128 or the Dobb~ et al U.S. Patent No. 4,706,888, the
disclosure3 of whiah are incorporated herein by reference.
~; 30 Al~o in FIG. 5, there i~ illu~ra~ed a fir~t formation 754
in the lowex area on the in~ide of the ~ide wall 734. Thi~
formation 754 defines a lug, bo~s or detent 7~4 that ¢xtend3
angulariy upwàrdly and inwardly from the wall 734 inside the
nozzle cap 60 to an edge or catch 755. In like manner, a lug,
35 bos~ or detent 756 in the lower area of the wall 738 ex~end3
inwardly from the wall 738 inside the nozzle cap 60 to an edge
:~ or catch 757.
As will be described in greater detail hereinafter, the

lugs 754 and 756 normally are positioned in the nozzle assembly
58 beneath the legs or prongs 72.
The blocking engagement of the leg~ or prongs 72 relative
to the lug~ or projections 754 and 756 normally prevents
S rotation of the nozzle cap 60 of the nozzle as~embly 58 u~til
the pull-away piece 20 i9 pulled away to remove the fork armq
69 from the locking position of each fork arm 69 between the
cylindrical portion 64 and a leg or prong 72, and unles3 and
until a user squeezes the side walls of the body 14 in the ~ide
10 wall areas 780 and 782 at the same time the u~er rotates the
nozzle cap 60.
The blocking position of the pronss 72 i~ ~hown in FIG~ 8.
Then, a~ shown in FIG. 9, when the wall area~ 780 ~nd 782 o
the body 14 are squeezed or pushed inwardly to move the legs or
15 prongs 7~ toward the cylindrica~~portion 64 and out of blocking
or catching engageme~t with the lug~ 754 and 756, the nozzle
cap 60 can be rotated clockwise or counterclockwise, a3 ~hown
: in phantom in FIG. 9.
As shown in FIG. 9, after the wall area~ 780 and 782 are
20 squeezed to move th~ legs 72 out of bloc~ing engagement with
respect to the lugs 754 and 756, partiGularly the lug 754, the
nozzle cap 60 can be rotated counterclockwise 90 to the SPRAY
position.
In thi~ position, the waterways 720 and 722 commu~icate
25 through the slot 750 and the slot 796 to the cylindrical cavity
704 for effecting a ~wirl of liquid to the out~et orifice 752
~: ~ in the front wall 744 of the n~zzle cap 60 thereby to effect
:~ the SPR~Y, mist or fog-like discharge of liquid from the nozzle
`cap 60.
30When the nozzle cap 60 i~ rotated clockwise 90 after the
prong3 or legs 72 have been squeezed inwardly, the lug or
; projection 756 then can move p~st the leg 72. :
Each lug 754, 756 has an upper surfa`ce 76~ extending to a
surface 762 that is close to parallel to the plane of the ~ide
~: 35 wall 734 or 738, the intersection of these 3urface~ 760, 762
being the edge or catch 755 or 757.
It will be noted that the~ extension tab 726 having
inclined side edges 784 and 786 is adapted to engage on one

side or the other the lug 754 or the lug 756 to prevent further
rotation of the nozzle cap 60, counterclockwise or clockwise
thereby to ensure that the nozzle cap 60 can only be moved from
the STOP position to the SPRAY position or from the S~OP
5 position to the STREAM po~ition.
With reference to FIGS. 2 and 10, it will be understood
that the mounting block 67 of the pull-away piece 20 has a
generally rectangular planar body 801 and i~ pressed downwardly
after placement over the top portion 22 to snap-fittingly lock
10 the mounting block 67 in the opening 68 in the top portion 22
of the body 14. At the same time, the fork arms 69, each
having a curved inner surface 802, are received through the
~: spaced apart slots or notches 70 in the top portion 22 at the
: front end thereof ant through the slots or notches 71 in the
15 rear edge of the top wall 730 of the nozzle cap 60, with the
curved surfaces 802 being received around the cylindrical
portion 64 of the body l4 and having lower ends 804 received
between the cylindrical portion 64 and the spaced apart leg~ or
prong3 72.
With the lower ends 804 of the fork arms 69 positioned in
thi~ manner, inward movement of the legs or prongs 72 when the
wall aress 780 and 782 of the body 14 are squeezed is
pr~vented.
A~ a result, if one tried to rotate the nozzle c~p 60,
25 such rotation i8 prevented, on the one hand by the fork arms 69
extending through the mating ~lot~ or notches 70 and 71 in the
top wall portion:22~of tbe body 14 and the top wall 730 of the
nozzle cap 60;and, on~th- other hand, by the blocking po3ition
of the fork arms 6:9 which~prevent inward movement of the prongs
30 72 to enable the~lugs ?54 and 756 to be moved pa~t the prongs
72 upon either:olookwise or counterclockwise attempted rotation
of the nozzle cap 60.
As best shown in FIG.~ 11, the pull-away piece 20 has at
the front end thereof a rectangular recess 806 which is adapted
35 to be re~eived over the extension tab 726. The curved surfaces
802 extend downward:ly and laterally on the inner side of the
fork arms 69 from the edges of the rectangular recess 806.
A top rear portion or pull tab 808 of the pull-away piece
substitute sheet-
:~
~ 7 ~J ~ U C lJ ~ ~
112l 3o jgo . IPEAIUS 19 AUG1993
20 has PU~L indicia 810 thereon.
Further, to facilitate pulling of the pull-away piece 20,
the rear underside of the pull tab 808 is beveled upwardly at
812 a~ shown in FIG. 12.
The mounting block 67 is positioned below the planar body
801 of the pull away piece 20 beneath a recess 815 in the
planar body 801 and is connected to fro~t and back edges 816,
817 of thi4 receqs 815 by three webs or fillet~ 818, as best
shown in FIG. 13.
The mounting block 67 has a curved lowex ~urface 820 with
a centrzl longitudinally extending slot 822 separating the
mounting block 67 into left and right prong portions 824 and
826. Each prong portion 824 and 826 ha~ an inclined surface
828, 830 which inclines upwardly and laterally outwardly from
-15 the curved surface 820 to a shoulder 832, 834, as best ~hown in
FIG. 13.
It will be under~tood that when the mounting block 67 i~
pushed downwardly through the opening 68, the inclined surfaces
82U and 830 engage the side~ o~ the opening 68 and the slot 822
20 allows the prong portions 824 and 826 to be deflected inwardly
until ~he shoulder~:832:and 834 are moved pa~t lower side edges
835 and 836 of the opening 68 and snap into a locki~g po~ition
:~ beneath the top wall portion 22 of the body 14 adjac~nt the
side edges 835, 836 of the opening 68. The cur~ed surface 820
~:25 will then re~t upon the upper surface of the cylindrical
~: portion 64 perhaps with a slight interference fit between the
cylindrical portion 64 and the underside of the top wall
~urface 22.
:A3 shown in FIG. 12, the planar body 801 ha~ ~ tran~verse
30 g~oov~ 840 in a lower ~urface 842 thereof to ~acilitate bending
of th~ pull tab 808.
The pull-away piece 20 provides tamper evident structure
for the nozzle assembly 58. In ~his respect, if the pull-away
piece 20 is broken or mi9Ying~ that is evidence that the nozzle
