I~Escp~Ipr~ L OF THE ~NVENTIQN
1 0 ` : '
In general terms, the enamel applicator and
doser plug, which constitutes the object of the invention,
is fastened to the mouth of the enamel container eith~r by
means of threading, or by méans of a simple press-fit
action, permitting also the axial relative displacement
between the two bodies, and existing means which impede
the accidental separatic,n of the assembly.
The pumping element is determined by a
~o cylindrical sleeve having a smooth initial Portion and
another posterior Portion affected bY a PluralitY of slots
or windows which Permit the entrance of the product
contained inside the case or container. A piston is aided
by a rear spring, in such a manner that bY being forced to
displacement against the action of the spring, by means of
a canula, ~oing out of the smooth portion of the sleeve
and being placed in the slot C3rrYing part, when returing
to the initial Po~ition a dose is taken throu~h the axial
orifice of the canula.
The PumPing element and the mouth of the
container are located inside a casing or housing of the
doser plu~, the free end of which having an external
threading for connection to a trunco-conical no~le from
which the applicator brush of the product is emergedJ

push-button.
The Product applicator brush is in turn covered
by the plug itself, or the cap, screwed over the no2~le,
thus avoiding the drying of the Product which has soaked
the bristles of the applicator brush.
An obturating element is Provided in order to
aid the function of sealingly closing the .~pplicator
brush, said element being located inside the cap and can
be axially displaced due to the assistance of an
intermediate spring. said spring makes the obturator
displace towards outside, the exit of which being limited
by a cap in such a manner that the mouth of the same is
applied a~ainst the conical surface of the no~le.

DE5CRIPTION OF A P~EFE~ED FORM OF EMBODkMENT
~ eferring to the numerals adapted in the
fisuresr it can be observed that the enamel aPPlicator and
doser Plug~ propo~ed by the invention, is constituted in a
first form of embodiment as indicated in fi~ures 1 and ~,
by a cylindrical casing 1 which is connected to the
threaded neck ~ of the enamel container 3. The pumping
device ~ is fastened to the neck 2 of the container in
such a manner that it, body is immersed in the bulk of the
product. It is determin~d bY a ~leeve 5 initiallY ~mooth
and in the remaining Part covered bY a PluralitY of a.xial
~ -5- 2~1~78~
1 slots 6, in the interior of which is piston can be
displaced ~not ~hwon in the figures) aided bY a spring
i which maintains the spring pushed towards the enlar~ed toP
7 of the sleeve 5.
Through the axial orifice 8 of the pumping
element 4, canula ~ is partially inserted which restson
the piston. The other end of the canula 9 is formed as a
housing 10 from which a small rigid conduit 11 i~ axiallY
emerged which is in turn telescopically inserted in the
prolonging tube 1~ which emerges from the other end of the
casing and i5 connected to the base of the bristles 13 of
the applicator brush of the product.
The casing 1 is laterally provided with a
window 14 through which the push-button 15 for activating
the pumping device 4 goes out. The Push-button 15 has a
"U" ~haped cross-section and the sides thereof
corresponding to the branches are of generallY triangular
LO 5hape having a very acute vertex which Presents a pair of
arc-shaped pins 16 which define the means for rotation and
connection to an interior axis of the casing not shown in
the figures. The end opposite to said vertex are
arc-shaped in order to de~ine a cam curve which during it,
L5 angular movement displaces the canula ~ by intermediate
use of ths Pushing piece 17, the Pushing being favoured
due to a front surface of the Pushins piece of a convexlY
curved shape and where a Passage orifice of the tube 1 L is
presented as it can be observed in figure L .
rhe fr~s end of the casing 1 is provided with
an exterior threading for the connection of the conical
no~le 1~ thruogh the axial orifice of which the bristles
13 of the product applicatior brush are emerged as shown
in fisure l.
.,
-6- 2~7~ ~
1 The conical no221e 19, a5 well ass the bristles
13 that emerge therefrom are totally closed by a cap 20.
This cap ~0 has an interior threading in order to connect
with the threadsof the trunco-conical noz21e 19 and inside
of the same there is also another obturating cap aided by
a ~Pring which shall bs observed hereinbelow in relation
to fi~ure 4.
with this disposition, by pressing with finger
over the lateral push-button 15, the Pushing piece 17
displaces the canula 9 and thus the Pumping device 4 is
loaded with a dose of the product to be ejected, 50 that
when the action over the said Push-button 15 is ceased,
the piston of the Pumpins device pushes the Product
through the canula 9, the rigid conduit 11 and tube 12 in
order to soak the bristles 1~ 50 that the user can
distribute the enamel on the nails.
Referring now specially to figure 3, an example
~o Of embodiment can be observed in which the activating
push-button of the pumping device 4 has annular ~hape and
is marked with numeral ~1. The annular push-button .1, bY
being displaced in the direction shown by the arrow can
axially displace the canula 9 50 that after said
displacement and as a conse~uence of the existence of the
spring which aids the Piston of the pumping device 4, the
dose of Product is ejected to the bristles 13. In thi~
case, the no~le 19 and the caP ~0 are not displaced since
the disPlacement is done by the annular push-button
It also can be assumed that the annular
push-button 21 is attached to a casing of small len~th
which is connected to the neck of a container .~ of an
axially movable form, i.e. a relative axial di~Placement
between said casing (and thus the annular push-button ,1
` 211~78~ ~
1 attached thereto) and the container 22 can be permitted,
with elements existing in order to avoid the accidental
separation of said elements. By being threaded the cap 20
to the no2-1e 19, the axial pressure in order to eject a
dose of product to the bristle~ 13 can be exerted directlY
on the cap 20. 8y later unscrewing the caP 20, the
bristles 1~ are alreadY soaked bY the product and ready
for carrYing out their painting function.
: '
In figure 4 an example of embodiment can be
observed which is functionallY identical to the one shown
in figure 3, but as to its external form it is appreciablY
changed since a cylindrical container 23 havin~ a small
diameter is used which is practically introduced in a
casin~ 24 of large length and a slightly larger diameter.
The casing 24i includes, in the lower part, a bevelled
portion 25 which allows the visibility of the lower part
of the cylidrical container 23.
In figure 4 it can be observed from the broken
lines that the container 23 is already carrYing the
pumping device fixed to the mouth of the same, the whole
assembly being inserted in the interior of the casing 24,
and preventing its involuntarY extraction due to the
existence of coniugated ribs fitting to each other, such
as those referenced with numeral 26 in said fi~ure 4. In
the Position ihown in figure 4 the container 23 occupies
the lower-most Position and the canula ~ can remain
inserted in the PumPing device making contact with the
piston in the Position of mounting the assemblY~ The
no2~1e 1~ re~ts over the external shoulder 27 of the
cylindrical casing 2~ bY screwing on to the neck 2~. This
position of the container 23 i~ maintaine~ stable due the
existence of the spring which helps the piston of the
Pumpins device 4.

1I n thi~ condition, by carr~ing out a relative
axial di~placement between th~ casing .4 and the container
23, which takes Place against the action of the latter
mentioned spring, the pumping device is reloaded and later
the bri~tles 13 of the brush are soaked when the original
position is reached. The said axial di3placement is made
pos3ible because of the existence of the bevelled Portion
~5 of the casing 24 since by holding the casing 24 by one
hand, the end of the container 23 can be activated bY
10thumb. A150 with said bevelled portion 25 the involuntary
exit of the product can be avoided when the whole a55emblY
is stored, since the free edge of said casing 24 is
practically levelled with the bottom of the container,
said casing resisting against compression overforcings
exerted thereon. In said figure 6 and more particularlj~ in
the cross-sectioned details which the cap 20 presents the
inside of the same can be seen and its structure can be
commented as indicated hereinabove. Inside ofthe same the
obturator .9 is located in a displaceable manner aided by
-o the spring 30 which maintain~ it pushed towards the
emergency Po~ition coinciding with the illustration of
figure 4. when it is intended to screw the cap 20 on the
noz21e 19, the adjustment of the mouth of the obturator 2~
on the trunco-conical portion, and also overpassin~ the
latter, of the no~le 1~ is initially carried out,
advancing thereafter only the cap 20 during the rotating,
thus the pressure of the spring ~0 maintains sealingly
closed the chamber occupied by bristles 13. BY unwinding
the cap 20, it bounces loose due to the action of the
,pring ~0 and then it i~ necessary to exert a sli~ht axial
force in order to separate the assemblY.
