NOZZLE CLOSURE MEANS FOR CONTAINERS
Albert II. Church, assignor to No-Kap Closures
(U. S. A.)., Inc., Providence, B. L, a corpora

Application ‘November 8, 1934, Serial No. 751,734
19 Claims.
My invention relates to improvements in nozzle
closure means for containers, cans, tubes, bot
ties or the like. While my invention is particu
larly adapted for use with collapsible tubes in
which at least a portion of the valve seat for the
oscillatable, substantially spherical valve closure
member thereof may be extruded simultaneously
‘with the extrusion of the tube. it’ is equally ap
plicable as a bottle nozzle closure means, pro
l0 vided, if desired, with a depending ?ange similar
' to the upper end forming ?ange of a collapsible
tube and also, if desired, with a nozzle extension
projecting downwardly therefrom adapted to ?t
within a cork to secure it to the top of the bottle,
16 or with the nozzle itself being provided with an
(Cl. 221-60) ’
which the valve action is air, liquid and chemical
resistant, and to this end I broadly provide, in
combination, a valve seat constructed of thin
more or less slightly yieldable metal preferably
in such a manner that it of itself may be slight
ly yieldable, and construct the valve itself pref
erably of a predetermined chemical resistant
preferably slightly yieldable composition mate
rial which functions in combination with the
metal of the valve seat to form a substantially 10
yieldable air and liquid tight joint at all times.
As a further precaution to insure an air tight,
liquid tight joint I preferably provide in the valve
seat a countersunk preferably resilient ?bre or
other type of washer to positively bear against 15
extension going around the neck of the bottle. the oscillatable valve at all times to insure a tight

the top of the container only may be extruded ment therein at all times.
20 or formed simultaneously with the formation of
Great di?iculty has been hitherto experienced
the nozzle and valve seat. The invention is
adapted to dispense materials in powder form
and more particularly is adapted to dispense ma
terials in plastic, semi-plastic partially lique?ed
25 form or liquid form and to provide at all times
a positive closure for the nozzle means thereof
which will not leak and has been proven in tests
not to leak with water, glycerine or other types
of chemicals over a long period of time.

‘
While I am aware that others have provided
nozzle closure means for containers, bottles, cans,
tubes and the like having at least a partially
spherical closure member functioning as a valve
and rotatably mounted in a suitable formed valve
35 seat in the nozzle thereof, so far as I am aware
these have been largely paper patents either im
possible to vmanufacture or only made at a. great
expense. I believe that I am the first, therefore,
to provide a nozzle closure means of this type
40 which may be manufactured on a practical com
mercial basis in the manner described herein and
which is positively liquid, chemical and air re’
sistant, and in which the valve forms preferably
with a countersunk washer a liquid chemical and
45 air resistant positive joint when in closed posi
in the manufacture of collapsible tubes, con
tainers and closure means therefor, in providing
a closure joint resistant to the speci?c chemicals
which may be contained within the contents of
said cans, containers, tubes, bottles or the like.
By employing plasticizable composition material
I have been able to select the materials of which
the valve is made to make it resistant speci?cally
against the known chemicals in the contents of
the container, for instance, resistant to mild
acids, alkalis, alcohol, other solvents, etc., and I
therefore construct the material of which my
valve is preferably made of predetermined chemi
cal characteristics to be so resistant.
Further objects of my invention are not only 35
to provide a nozzle closure means of the type
mentioned above which may be readily and sim
ply manufactured, but also to provide one which
will positively oscillate and which will function
to close or open the nozzle at all times. I pref
‘erably provide a turning lug projecting upwardly
40
through the open end of the nozzle to limit the
oscillatable movement of the valve member from
an open to a closed position by the sides of said
lug abutting the sides of the upper end of the
nozzle. I also provide means to positively pivot
tion, and which may be readily manufactured in
the simple mannershown herein and at a cost to the valve member on a de?ned horizontal axis so
make this type of a valve closure means possible that it may positively function at all times and
under competitive conditions with other types of ,not tend to slip around within the‘ valve seat,
50 closure means now on the market.
As stated, hitherto the great di?iculty with de~
vices of this description has been that the valve
action is not air or liquid resistant. An object
of my invention, therefore, is to provide a nozzle
55 closure means of this general description in
so that the end or ends thereof will not come
into accurate alignment with the nozzle‘ end or
ends. In- order that the turning lug may posi
tively function to both open and close the valve,
1 construct it so that in closed position the upper
surface thereof projects substantially tangen 55

tially from thetop of the valve, so that it may be
readily opened, and provide the end of said lul;
having a tangential upper surface with an up
turned portion to form an upwardly projecting
tip or projection for the ready oscillation of said
valve from an open to a closed position.
Further features of my invention relate to the
improved method of manufacture of and certain
details of construction thereof so that it may be
10 readily manufactured in a commercial and prac
tical manner. 'nius I preferably mold the valve
closure member with ?attened opposite sides to
assist in forming an axis of rotation therefor
and I provide centrally thereof outwardly pro
jecting pivot lugs of a length with the said ad
the valve seat simultaneously with the extrusion
of the nozzle and also, if desired, supplemental
metal saving recess means may be formed'in the
lower surface of said thickened portion to save
the expense of additional metal; or, if desired, 6
-the valve seat may be formed from an inwardly
depending annular ?ange projecting inwardly
from said nozzle. If desired, however, the coun
tersunk washer-receiving recess may be readily
formed in the upper portion as well as the‘ lower
portion of said valve seat during the extrusion
' process.
Further objects of my invention therefore are
to provide a novel method of pressure molding
of selected predetermined chemical resistant com
jacent central valve portion of substantially the
position material in which a valve of the desired
exact diameter of said sphere, so that if the
type may be readily made at a minimum cost.
Further objects of my invention are to provide
a novel type of extrusion apparatus and process
for manufacturing the nozzle portion of my in 20
vention with a suitable lower partially spherical
valve seat portion in a thickened portion of said
valve be molded in hemi-spherical molds, the
mold line will substantially pass through the cen
ters of said ?attened side portions and said lugs
to permit the ready removal thereof in an easier
manner than if indentations were provided in
said flat portions which would be hard and al
most impossible to remove from the molds; and,
as the total length of said pivot lugs taken
through the axis thereof is not greater than that
of the diameter of said sphere, they may
be more readily removed from the molds. A fur
ther detail in the construction of my valve which
30 makes pressure molding thereof possible is the
particular shape of the turning lug I preferably
employ which includes a curved lower surface
and a ?at upper surface substantially tangential
to said spherical valve and terminating in an
35 upward bent outer end meeting said lower sur
face to form an outwardly projecting lug, being
so shaped for a double purpose, namely, so that
said integrally molded lug may be readily pivoted
out of a hemi-spherical valve mold by pivoting
40 it therefrom on the point of contact of said mold
with the lower surface of said lug, and to pro
vide a turning lug engageable by the finger which
will oscillate the valve in either direction.
A further feature of my valve construction is
that I provide means for readily pivotally at
taching it on a ?xed axis within the relatively
thin upper portion of the nozzle wall, it being
only necessary to insert the valve closure mem
ber within the partially spherical extruded re
cess or lower valve seat portion and press in
wardly diametrically opposite portions of said
relatively thin nozzle upper wall against said
diametrically opposite ?at valve portions to cause
the pivot lugs to be imbedded within the nozzle
wall ‘to form sockets to receive said pivot lugs
55
to provide an axis of rotation for said valve.
Further features of the inherent construction
of my improved closure device are that I provide
a nozzle which may be readily extruded from a
circular, annular or other type of blank in the
form of a nozzle having a partially spherical
lower valve seat portion in a thickened or- lower
portion thereof and a relatively thin upper wall
projecting substantially vertically upwardly from
said lower valve seat portion which, after the
insertion of the valve member therein, may be
readily crimped downwardly over said valve to
provide a supplemental partially spherical upper
valve seat portion for' the upper portion of said
70 valve to ?rmly retain it in position against said
'washer where employed and said lower valve seat
portion formed during the extrusion process.
A further feature of my particular construc
tion is that the countersunk annular recess for
76 receiving the washer may be readily extruded in
nozzle preferably having a countersunk washer
receiving recess therein and with the lower sur
face of said thickened portion underneath said 25
valve seat being partially removed to save metal;
preferably extruded simultaneously with a ?ange
projecting outwardly from a downwardly depend
ing nozzle extension or a complete container
or tube as shown.
30
Further features of my invention relate to the
various features of construction of my valve and
nozzle members hitherto described which func
tion to provide a novel method of assembling
them into a nozzle closure unit which may be 3,5
entirely manual, semi-automatic, or completely
automatic.
-
Further features of my invention are to pro
vide an improved apparatus for such assembly,
being either fully automatic or requiring at the 40
most a single operator. By providing the valve
structure hitherto described and the valve seat
structure also described in said nozzle, I have
provided a construction whereby the nozzle may
be readily mounted on a rotatable ring or con
45
veyor and the following sequence of steps per
formed thereon during intermittent intervals of
movement of said rotatable ring or conveyor,
namely, (1) the mounting of said nozzle on suit
able means on said conveyor, (2) manufacture, 50
shaping and insertion of the ?bre washer within
the countersunk valve seat in the lower valve seat
portion of said nozzle or upper valve seat portion,
if desired, (3) the insertion of the oscillatable
valve closure member so as to abut said washer 55
and lower valve seat nozzle portion in correct
alignment, (4) the downward crimping of said
nozzle upper wall toprovide a partially spherical
upper valve seat portion enclosing said valve
member and ?rmly securing it against said 60
washer and said lower valve seat portion, (5) the
inwardly pressing diametrically opposite portions
of said relatively thin upper wall against said,
diametrically opposite ?attened valve portions
t?) form ?at abutting surfaces to accurately align 65
the axis of oscillation of said valve within said
nozzle and to simultaneously press the pivot lugs
where employed into the relatively thin nozzle
wall to form sockets therein to receive said pivot
lugs to positively provide an axis of rotation for 70
said valve member to keep the discharge passage
thereof in the desired alignment with the dis
pensing holes at the upper and lower ends of
said nozzle when in open position, (6) oscillating

of assembly steps to be performed thereon during
the intervals between said progressive advance
ments. It is obvious that any type of continuous
30 conveyor may be employed and in my preferred
embodiment I preferably employ a ring rotatably
mounted on a suitable standard on which the
desired tools to accomplish the steps described
are mounted on the respective stations thereof
35 to perform the actual‘ work thereon at these
stations between the intermittent intervals of
movement of said conveyor or ring.
Further features of my invention are therefore
to provide a novel type of apparatus for this
40 method of assembly which may be done either
by hand, semi-automatically, or fully automati
cally to save the number of operatives required.
While‘ my invention is particularly applicable
for use in the manufacture of collapsible tubes,
45 cans, containers, etc., which may have either the
upper portion or entire body thereof simultane
ously extruded with the formation of the nozzle, it
is apparent that my invention may be equally
applicable to bottle closures which may also be
50 provided with an outwardly projecting annular
?ange analogous to a can or container top or
collapsible tube top and if desired the nozzle
portion may be extended below said spherical
valve seat portion in the extrusion process to
55 provide means whereby an annular cork or other
device may be employed to surround said extruded
nozzle for insertion within a bottle neck. ‘If
desired, the entire valve closure member may be
constructed hollow and the valve seat portion
60 of the nozzle similarly enlarged if necessary so as
to receive and dispense a predetermined bulk of
powder, liquid, or other material contained within
said hollow valve. For this purposelI preferably
provide the hollow valve seat portion with a single
65 discharge end and I preferably construct the co
operating surfaces of the nozzle side wall and
the nozzle inlet and outlet holes so that the pre
determined bulk holding hollow valve may be
moved to three positions, namely (1) a position to
70 ?ll said hollowvalve when the bottle or container
is in inverted position, (2‘) to a loaded position in
which the hollow valve is turned so that the dis
charge vent is completely sealed by the side wall
of the nozzle, which position may provide a con
75 venient loaded position taking a much less time
open dispensing position.

means it may be employed as a bottle top as
shown in Figs. 11 and 13. My improved nozzle
closure member l0 includes a preferably hollow
preferably extruded preferably metal nozzle 35
member l8, preferably having the lower portion
18 thickened as at 20 and having a central dis
pensing hole means 22 therein, said lower por
tion i8 preferably having a partially spherical
preferably slightly yieldable lower valve seat 40
portion 24 on the inner surface thereof extruded
thereon at the same time that the nozzle portion
I6 is being extruded, and also extruded simul
taneously with the flange I2 if employed, and
the container or tube side wall I 4 or, if desired,
simultaneously with the nozzle extension 26 as
shown in Figs. 11, 13 and 15. In the embodiment
shown the lower valve seat portion 24 is pref
erably substantially hemi-spherical. The ?ange
I2 may, as shown in Fig. 1, be the means to
secure said nozzle member to a container, bottle,
tube, can or the like such as by forming the wall
I4 integral vtherewith as shown in Fig. l or other
means may be provided, if desired, to secure said
bottle, tube, can, container or the like, such as by
providing an annular cork member 28 adapted
to surround the extruded nozzle portion 26 as
shown in Figs. 11 to 15 adapted to be slightly
yieldable contained within the bottle neck.
My invention broadly includes a preferably 60
substantially spherical valve closure member 32
mounted within the upper end of said nozzle i6
and provided with a discharge vent or passage 34
and a suitable axis of rotation 36 and preferably
a turning lug 28 whereby said valve closure mem 65
ber 32 may be oscillated to positions bringing the
discharge vent or passage 34 thereof in align
ment with the inlet hole 22 in the lower portion
of said nozzle and/or the outlet hole 48 in the
upper portion of said nozzle. While I am aware 70
that substantially spherical valve closure mem~
bers of this general type have hitherto been pro
vided for nozzles, so far as I am aware they have
tended to leak, and to aid in preventing the leak~
age thereof I have provided washer nieans 54 75
2,127,486
adaptably to be countersunk within the valve
seat 44 formed in said nozzle said valve seat 44
includes the lower valve seat portion 24 and the
upper valve, seat portion 46 to be described.
Where a collapsible tube is employed I prefer
ably suitably countersink the circular washer 66
5
side portions 68 on said valve member 32 as more
particularly shown in Figs. 4, 7, and 8 provided
with pivot lugs 66 preferably having rounded
ends as shown and proferably projecting out
wardly centrally of said ?attened side portions
portion 24, but may, if desired, as shown in Figs.
58, and of a length with said adjacent central
valve portion, of substantially the diameter of
the sphere of which my improved valve member
15 and 17 countersink said washer recess 42 in
is preferably molded for a double purpose, (1) so '
in a countersunk recess 42 in the lower valve seat
10 the upper valve seat portion of the nozzle.
As to be explained later in connection with
Figs. 19 to 22, I preferably extrude my improved
nozzle member l6 and simultaneously provide it
with a lower’ valve seat portion 24 in a thick
15 ened portion of said nozzle and I may simulta
neously therewith extrude the annular washer
receiving recess 42 therein. In order to save
metal I also preferably provide metal saving re
cess means preferably in the form of an annular
20 groove 48 on the lower surface of said thickened
portion 20 or I may, as shown in Fig. 10 so con
struct the recess 48' as to substantially form as
the lower valve seat portion 24 the annular
slightly yieldable ?ange 24' projecting arcuately
that lugs 60 will not be of such a ‘length as to 10
prohibit their being removed from the molds,
they being normally so placed as to lie substan
tially on the mold line between the two hemi
spherical molds, and (2) so that they may be
readily dropped to‘the desired feeding position
within the diameter of said nozzle against the
partially spherical lower valve seat portion 24
thereof. Portions ‘of said nozzle member side
wall 60 are diametrically pressed flatly inwardly
as at 59 against said ?attened valve sides 58 to 20
assist in providing an axis of oscillation for said
valve portion 32 and to form sockets 66 therein
as shown in Fig. 4 to receive said pivot lugs 60
of a greater thickness than the depth of said
recess 42 to at all times closely engage the oscil
latable valve closure member 32 to form an air
diametrically of said wall 56 to provide an axis
of oscillation for said valve member 32,_and the
upper portion 52 of said vertical nozzle member
side wall is preferably crimped downwardly over
said rotatable valve member to form a hollow
partially spherical upper valve seat portion 46
having a central dispensing hole means 46.
Said valve member 32 is also provided on the
upper end thereof with a turning lug 38. Said
lug 38 is preferably formed with a curved lower
surface ‘I2 and a flat substantially tangential
upper surface ‘I4, terminating in an upwardly
bent rounded outer end 16 meeting said curved
lower surface ‘I2 to form an outwardly projecting
lug ‘l6 projecting radially outwardly from said
valve member 32, being thus shaped for a double
purpose, (1) so that said turning lub may be
readily removed from a hemi-spherical mold on
pivoting said closure member therefrom, the
inner end of the lower curved portion 32 forming
an axis for said pivoting, and (2) to provide
means whereby the closure member 32 may be
readily oscillated in either direction, namely, to

portion and to close by grasping the inner por
and liquid tight seal at all times therewith, and
tion of the upwardly projecting lug ‘I6 thereof,
25 inwardly substantially centrally of the side wall
50 of said nozzle. In my preferred embodiment
each recess, namely the washer receiving recess
42 and the annular metal saving recess 48, are
preferably concentric with the dispensing hole
30 means 22 in the lower portion of said nozzle sub
stantially centrally of the lower substantially
hemi-sphericai valve seat portion 24. After the
extrusion process, the upper portion 62. of the
side wall 50 of said nozzle projects substantially
35 vertically upwardly from the upper edge of said
lower valve seat portion 24. In the embodiments
shown in Figs. land 22, the annular ?ange l2
projects outwardly and downwardly from the
lower portion 54 of said nozzle wall 50.

As stated hitherto. in order to prevent leakage
through my improved valve closure means I6, I
preferably provide a washer 56, mounted in said
countersunk annular washer receiving recess 42,
preferably constructed of fibre, leather, rubber
45 or other suitable preferably resilient material
50 being constructed preferably of material where
liquids are employed resistant to the chemical
constituents thereof.

amount limited by said turning lug 38 abutting
opposite edges of said dispensing hole means 40
In the preferred- embodiment shown, I prefer ' in said hollow crimped upper yalve seat portion
ably extrude the nozzle portion l6 and integral 46. As stated, said valve member 32 is also pref
55 ?ange l2 where employed and tube or container erably provided with a discharge vent 34 either 55
side wall l4 where employed or nozzle extension
26 where employed of metal. And whereas I
may make my improved valve member 32 of
metal to provide a metal to metal contact, this
60 is not at all times thoroughly air and liquid
proof and I therefore preferably construct my
improved substantially spherical valve member
32 of predetermined chemical resistant compo
sition material and one of which the constit
65 uents thereof may be predetermined to be resist
ant to any speci?c chemicals contained in the
contents of the container, such as mild acid,
weak or strong alkali, alcohol, or other solvents,
etc. Said improved valve member 32 is pivotally
70 oscillatably mounted on said'valve seat 44 on a
horizontal axis 36 against said washer56. In
order to provide a suitable axis of rotation and
a. construction which may be pressure molded in
two superimposed substantially hemispherical
75 molds, I provide diametrically opposite ?attened
at one end thereof or passing therethrough. of
such a size and so located relative to the center
of said valve, and said nozzle side wall 50 and the
upper and lower dispensing holes 40 and 22 re
spectively of said nozzle l6 are of such a size and 60
shape that said discharge vent or passage 34 '
may be rotated into alignment with the respec
tive discharge hole means 40 and 22 in the hollow
ends of said nozzle valve seat 44 with the out
‘wardly projecting end 16 of ‘said lug abutting 65
one edge of said upper valve seat hole or said
valve member 32 with its discharge passage 34
may be oscillated to have the respective upper
end 35 and lower end 31 thereof closed by said
nozzle side wall 50, with the lower portion of said 70
side wall 12 of said turning lug substantially
abutting the other end of said upper valve seat
hole 40, if desired.
While the improved washer 56 is highly desir
able, it may, if desired, be omitted or inserted 76

2,127,465
as shown in Fig. 15 ina suitably countersunk hole
42 in the upper valve seat portion 46. While I
have shown, for reasons to be explained, my im_
proved type of means for oscillatably pivotally
mounting the valve closure member 32 in said
nozzle, in place of the pivot lugs 60 hitherto de
scribed, I may as shown in Fig. 9 provide suit
able sockets 50' in the ?attened side portions 54
of the valve member to receive the pivot lugs 05'
from the nozzle side wall 52 when di
1.0 formed
ametrically opposite portions of said side wall
are pressed inwardly as hitherto explained. The
vent or passage 34 of my improved valve member
is preferably shown located substantially near
15 the center thereof and passing therethrough but
it is obvious that if desired it may be located along
the side thereof as suggested in Fig. 13, or through
any portion thereof. It is also obvious that the
valve seat 44 including the lower valve seat por
.go tion 24 and the upper valve seat portion 46 may
may as shown be applied to the neck 30' of a liq
uor bottle and in addition to the discharge pas
sage 34 is provided with the air inlet passage 18
to rapidly admit air within the bottle to permit
the rapid discharge of the liquid contents there
of through the discharge passage 24 of said valve
member 32'‘. It is apparent, however, that the
discharge passage 84 may be constructed at the
side of the closure instead of through it as the
air inlet passage 18 shown in Fig. 14, or that, 10
said discharge passage 34 may comprise any de
sired part of a sphere up to a hemi-sphere. If
the discharge passage 34 be located at the side
however and substantially enlarged, it is not any
wherenear so desirable as the type speci?cally 15
shownrherein for ease of manufacture and as
sembly, but may for some features of my inven

the manner shown.‘ While I preferably employ
an extruded metal nozzle it is apparent that if
desired the nozzle portion may be ‘molded or ex
I have shown in Figs. 15 to 18 embodiments of
my invention adapted to dispense a measured 20
dose of predetermined bulk from the container
and for this purpose I have enlarged the vent
34“ so as to substantially take up the entire
interior of said valve member 3211, and I have
truded out of composition or the like material,
cast or otherwise fabricated and while I have
correspondingly enlarged the adjacentv substan
tially spherical valve seat portion 44* of said
preferably constructed our improved valve clo
nozzle wall. The hollow closure and vent are
preferably of such a size and shape and said noz
sure member of molded composition material, it
may if desired be suitably fabricated in any de
80 sired manner out of other material;
As ex
plained hitherto, by constructing the valve seat
of slightly yieldable metal material and by con
structing the valve of slightly yieldable com
‘ position material I have found that a true coop
35 eration exists therebetween, providing substan
tially an air and liquid proof joint at all times
and one in which there is substantially no wear
as in a metal to metal contact, permitting the
use of my improved nozzle closure means over a
long period of time. In order that a more slight
ly yieldable lower valve seat portion 24’ may be
provided, a. larger metal saving recess 46' may be
provided and particularly when extruding alu
minumI may extrude the ‘lower valve seat 24'
in the form of a slightly yieldable annular ?ange
depending arcuately inwardly from the center
portion of the nozzle side wall to the central dis
pensing hole 22.
As explained, I have shown in Fig. 5 the axis
of rotation of the valve member 32 on said nozzle
member I! formed not only by the ?attened side
portions II of the valve and adjacent ?at por
tions I. of the nozzle side wall but in place of
the pivot lugs projecting outwardly from the
valve into sockets 64 formed in the adjacent
nozzle wall, I have provided the recesses ill’ in
‘said valve to receive the pivot lugs 58’ formed in
said nozzle side wall when said nozzle side wall
is pressed inwardly on diametrically opposite
points thereof in the manner hitherto explained.
zle side wall and lower and upper dispensing
hole means 22‘ and 40' thereof respectively are 30
preferably of such a size and shape that said hol
low closure vent 34b may be rotated into align
ment with said lower dispensing hole means 22"
when said closure means is inverted to permit re
ception of said measured dose or quantity within 35

lug 38 abutting one edge of said nozzle hole means

position closure member 32‘) against said metal
valve socket 44‘ to bring said hollow closure vent 40
34b opposite said nozzle side wall 50‘ into inter
mediate loaded or cocked dose or drink-holding
position, so as to be frictionally retained there
in; or, rotated into alignment with said support
dispensing hole means 40. to expel said measured 45
dose therethrough with said turning lug 38 sub
stantially abutting the opposite edge of said up
per nozzle hole means 40‘.
I have shown in Fig.
15 this embodiment of my invention applied to a
neck 30' of a liquor bottle provided with the elon
gated nozzle extension 26‘ and being secured
within said neck by the annular cork 28, the
?ange l2 in this instance being omitted. While
it is possible to extrude this nozzle it is not so
easy as the extrusion of the other nozzles shown 55
and described hitherto and if desired the nozzle
portion l8b may be cast, stamped .or otherwise
shaped for this embodiment. I have shown in
Figs. 1'7 and 18 an embodiment of my invention
I have shown in Figs. 11 to 18 various forms of
my invention particularly adapted as closures for
bottle tops, the embodiments shown in Figs. 11
similar to the embodiment shown in Figs. 15 and 60
16 but particularly adapted for dispensing a
measured dose of powder. In this instance the
lower nozzle discharge port 22'' is made relatively
to 14 being constructed substantially similarly
small so that the closure member 32') may be os
to my invention as shown in Fig. 1 applied to a
cillated or rotated into three positions, namely 65
the filling, loading, and dispensing positions, as
shown in full or dotted lines respectively therein.
In this instance the lower nozzle extension 26b
is widened to fit outside of the neck 20' of the
bottle and is provided at its lower extremity with 70
collapsible tube except that the side wall of the
tube I4 is omitted from the ?ange l2‘, the nozzle
II‘ is extended downwardly as at 24 and provided
with an annular cork ring 20 for securing my im
70 proved closure means within the bottle neck 30.
In the embodiment shown in Figs. 11 and 12, the
discharge passage ‘84" of said valve may be ta

the inwardly projecting lip 29 providing means
to secure my improved nozzle closure member Iii
to the bottle. In this embodiment the nozzle
means lic may be conveniently molded.
As stated hitherto, I have preferably pro 75
7
2,127,465
vided in the speci?cdetails of my construction
both a valve closure member 32 which may be
readily fabricated in a simple manner and a noz~
zle portion I8 which ‘may be also extruded or
otherwise fabricated in a simple manner, the noz
zle being preferably constructed of metal and
the valve member being preferably constructed
out of molded composition material so as to yield
ingly abut each other and form an air and liquid
10 tight non-wearing joint in use better than it is
possible ‘to obtain by composition against com
position or metal against metal. I have also
constructed the details of my improved valve
be employed, I preferablyemploy one of insol
uble phenol formaldehyde intermediate conden
sation product type such as Bakelite, or insol
uble urea formaldehyde intermediate condensa
tion product or an insoluble cellulose acetate
product'or in fact any suitable type of moldable
preferably resilient composition material. With
the widespread range of composition materials
possible, it is obvious that I am able to select
a composition material particularly resistant 10
against the chemicals in the‘known contents in
the container for which my improved nozzle clo
sure means is desired to be used. Thus, for
instance, if it would be desired that the closure
structure with a view to a simple method of its
-15 manufacture.v I thus, vas explained, provide a ' member be resistant to alkali or weak acid, I 15
substantially spherical slightly yieldable closure preferably employ an alkali or. acid resistant in
valve member preferably consisting of hemi
spherically molded predetermined chemically re
sistant composition material having the diamet
'20 rically opposite ?at sides 58, having the pivot lugs
6|!v projecting outwardly centrally thereof, of a
length with said adjacent central valve portion
of substantially the'diameter of said valve for
easier removal from a heml-spherical mold and
25 for easy insertion within said nozzle member
with said mold line passing therethrough and a
turning lug 38 at the upper end thereof prefer
ably having a curved lower surface 12 and a ?at
substantially tangential upper surface‘ 14 termi
30 nating in an upwardly extending outer end 16
, meeting said curved lower surface ‘I2 to form an
outwardly projecting turning lug ‘l6 shaped to
be removed on pivoting thereof from said hemi- .
spherical valve mold and. a discharge vent 34
35 therein or therethrough substantially at right
angles to‘the diametrie axis of said pivot lugs 60.
As stated hitherto, my improved valve closure
member may be constructed in this specific man
ner out of any suitable material, but for the rea
-40 sons described and for the additional reason that
composition material may be brightly pigmented
or otherwise colored with any desired color to
provide an attractive contrast with the metal
nozzle, I preferably construct it of predeter
.45 mined chemical resistant composition material.
While I have preferably formed the axis of rota
tion thereof by providing the substantially spher
ical closure member with diametrically ?attened
sides 58 and‘ pivot lugs 60 projecting outwardly
50 centrally thereof of less total length than the
diameter of said sphere for easy withdrawal from
the mold and insertion within the nozzle, it is
obvious that in place of pivot lugs I may provide
soluble phenol formaldehyde intermediate con
densation product specially treated'to make it
acid and/or alkali resistant. If I desire a valve
member resistant to alcohol, I preferably employ 20
an insoluble urea formaldehyde intermediate con
densation product or I may if desired employ a
cellulose acetate product or any of a great many
possible composition materials preferably so se
lected as to be resistant to the particular chem
icals in the'contentsgof the container.
Employing these materials it is possible to man
ufacture my improved valve member 32 by pres
sure molding in two superimposed hemi-spherical
molds. 'I'he'hemi-spherical molds are preferably 30
so shaped as to provide the ?attened sides 58
and the pivot lugs 60 projecting outwardly there
from substantially centrally between the hemi
spherical molds of a length with said adjacent
central valve portion of substantially the diam 35
eter of said valve and molds. It is apparent,
therefore, that the mold line will be formed sub
stantially centrally of the?attened portions 58
and through the pivot lugs Bl] to permit the easy
withdrawal of said pivot lugs from the mold. 40
Thus the particular construction I employ to
provide an axis of rotation for the valve member
is constructed with a view of its easy manufac
ture or molding.
'
One of the molds is also shaped to provide
said closure member with a turning lug 38 at
the upper end thereof in the manner hitherto
described namely preferably with a curved lower
surface 12 and a ?at substantially tangential up
per surface 14 terminating in an upwardly bent
rounded outer end 16 meeting said lower surface
to form an outwardly projecting turning lug 38.
To provide the discharge vent passage 34 I pref
the pivot recesses 60' as shown in Fig. 10 or other
.55 types of pivot means, such recesses or other
types of pivot means being not however so easily
erably suitably mount within the molds substan
tially centrally thereof as desired suitable pin
withdrawn from the molds, and _I may in place
of the side portions 58 and lugs 60 provide any
type of oscillation axis forming means. While
60 the turning lug 38 at the upper end of said clo
arate the hemi-spherical molds, remove said pin
sure means is preferably constructed in the man
ner. described ‘with a double function of easy
removal from the mold and being operable to
be actuated by a ?nger to readily oscillate the
65 valve in either direction, it may, if desired, be
constructed in other ways than in the specific
manner shown.
Y
»
As stated hitherto, for the reasons given above
and as a plastic composition material may be
70 readily pigmented or otherwise colored to provide
. an attractive, appearance, I preferably construct
substantially spherical closure member ofv
_ hemi-spherically molded, predetermined chemical
resistant composition material. While any suit
76 able type of plasticable composition material may
means.
When the molding is complete I sep
means from said valve member to provide a dis
charge vent in said valve member substantially
at right angles to the diametric axis of said pivot (ID
lugs, and pivot said valve member substantially
at about the point where the lower lug surface 12
joins the valve member to remove said turning
lug from its hemispherical mold. If desired, the
pin means may project through the molds to as
sist holding them together and may be removed
prior to separation of the hemi-spherical molds.

ited to the speci?c embodiments of article and
that various deviations may be made therefrom 70
