Pencil-shaped device for -the application of cosmetic composi-tions
Many cosmetics are offered in a pencil-shaped casing
which contains a column of cosmetic composition, because this has
the advantage that the casing serves both as a container for the
composition and also makes it possible to handle the composition
when it is applied. For such sticks or pencils, a number of
different constrwctions are known, determined largely by the type
and consistency of the cosmetic composition. A typical example of
a first group of such pencils are the lipsticks, the composition
of which is of a pasty-wax-like nature and which is normally
contained in a sleeve with a lifting mechanism - in most cases a
twist-and-lift mechanism. Another group of such pencils comprises
cosmetic compositions of a harder nature which are used in the
manner of a writing pencil and which are often encased in a wooden
sheath. This type includes eyebrow pencils, kohl pencils and the
like.
When any cosmetic pencils are used, two essential reqwire~
ments must be met: on the one hand, the cosmetic composition may
need to be appliea to an area of the skin and, on the othex, it is
frequently necessary to define sharp lines. These two require-
ments are not easily met by the prior art pencils, because the
contour of the pencils changes during usage and in particular the
pencil point is lost. It is true that even after prolonged use of
the pencils, skill and practice can make it possible to control an
attractive application of the cosmetic over an area, but in any
case, the application of sharp lines necessitates additional aids.
For example, pencil-like cosmetics such as eyebrow penci]s, kohl
~' ~
2 - 12S~0~0
716 do-4
pencils and the like have to be sharpened time and again with a
sharpening tool in order to guarantee the production of fine lines.
This is a bothersome and fairly dirty affair during which consider-
able quantities of the cosmetic are wasted. In the case of
lipstick and similar pencils of a pasty-wax-like nature, such
sharpening is not possible and in these cases, many users employ
a fine brush with which they take some of the composition out of
the pencil and apply it as a line.
A further disadvantage of the known pencils lies in the
fact that they are only suitable for those cosmetics where the
column of cosmetic composition is in itself of a stable form.
This applies to the previously described lipsticks, eyebrow
pencils, kohl pencils, etc., but not to the creamy-soft compounds
such as for example rouge, eye shadow and the like. In the past,
creamy-soft cosmetics have normally been taken from a bowl-like
container and applied by means of a fine brush or a pad or a
corresponding applicator material which holds (stores) a certain
supply of composition and can then deliver it to the skin in the
desired quantity.
The object of the invention is to eliminate the
disadvantages outlined above. The invention is based on the
problem of providing a device for the application of cosmetics and
which is suitable for all types of cosmetics ranging from hard
through wax-like to creamy-soft and which, without additional aids
and even in the case of unskilled users, permits of both a flat
application of the cosmetic composition to the skin and also the
forming of sharp lines, throughout the entire useful life of the
cosmetic.

Adopting as the premise a sleeve within which there is
a column of cosmetic composition which can be extended by a
lifting mechanism, this problem is according to the invention
resolved in that the delivery end of the sleeve is occluded by a
head part which carries over at least a part of its surface an
applicator material for holding and subsequently applying the
cosmetic composition and which is provided with outlet orifices
through which the cosmetic composition can emerge from the sleeve
towards the applicator material.
The invention provides the cosmetics industry with a
novel applicator device, the special feature of which is that
there is at the delivery end of the sleeve containing the
composition an "applicator head" which consists of the head part
and the applicator material. The head part and the sleeve can
thereby consist of one piece, although the head part may also be
a solid possibly somewhat flexible body which is mounted on the
sleeve like a cap or which can be inserted into the sleeve like a
plug and screwed, glued or connected in some other way to the
sleeve. Its outer contours determine the outer contours of the
applicator material which it carries, the applicator material
being any material which is capable of accommodating cosmetic
composition which is supplied through the outlet orifices of the
head part and of passing it on for subsequent application to the
skin. For example, the head part can for this purpose be provided
with a covering of a woven or knitted material, e.g. a gauze, a
thin open-celled sof~: foam material or a tear-resistant fleece
material. Similarly, though, it is also possible to provide the
_ 4 - ~ Z S9 ~ ~
71600-4
head part with brush hairs or flocking. Thus, a wide choice of
applicator materials is available for cosmetic compositions of
different types and consistency.
The application head according to the invention permits
of a substantially improved application of the cosmetic composi-
tion. As a result of the application head, in fact, the cosmetic
composition no longer emerges freely in stick form when the
lifting mechanism is actuated and then, as with known liptsticks,
have to be applied by direct contact of the stick with the hand,
but now passes through outlet orifices in the head part to the
applicator material where it is held ready for subsequent applica-
tion by means of the applicator material and after use is further
supplemented by renewed actuation of the lifting mechanism. This
offers numerous advantages which cannot be attained with any of
the known pencils.
~ or example, the predetermined outer contours of the
applicator head ensure that during the entire period of use of
the pencil, constant application conditions apply. The outer
contours can for example be cone-like or spatula-like and may
expediently be such that they comprise both curved and flat areas
as well as areas with a stamped-out point of edge so that the
cosmetic composition can be applied with the same stick but either
flat or in the form of dots, fine strokes or clearly defined
outlines, as desired. Since the outer contours of the applicator
head remain unchanged during use, these manners of application are
retained in their en1.irety until all the cosmetic composition has
been used up, i.e. there is no longer any need for sharpening nor
~.~
; ~ '
' ~ ' ' ~ . .
~. : .. :
5 lZS9~
71600-4
for any additional aid for drawing fine lines and the like.
Accordingly, the cosmetic composition is al~o almost completely
utilised since there are virtually no losses.
Furthermore, the application conditions can also be so
optimised that even unpractised users can achieve outstanding
results. The lifting mechanism can, namely, be actuated easily
so that the cosmetic composition is held ready by the applicator
material in a controllable quantity which is always accurately
matched to the particular application. In consequence, the risk
of over-dispensing composition onto the skin which is true with
conventional sticks, is avoided. Dispensing of the composition
which is held ready for application can be further facilitated in
that the lifting mechanism admits of only portionwise emergence
of composition from the sleeve, for example in that there are
associated with it notches into which the lifting mechanism can
successively engage.
The disposition and configuration of outlet orifices in
the head part can be chosen according to particular requirements.
It is possible evenly to distribute over the entire outer face of
the head part a number of equal-sized outlet orifices in order to
provide the applicator material with an even amount of cosmetic
composition along the entire outer contours of the head part.
Similarlyl the number and/or size of outlet orifices may also
differ in individual partial zones of the head part if it is
intended that these partial zones hold ready different quantities
of cosmetic composition, for example in the case of sticks where
for the most part it is either a more all-over or a more line-wise
~' .

71600-4
application of the cosmetic composition which is required and
therefore a different cross-section of outlet orifice is
appropriate in the corresponding areas of the head part. Further-
more, it is possible to provide outlet orifices only in one area
of the head part, in which case, then, often a single outlet
orifice is sufficient, for example in the tip of a cone-shaped
head part or in the middle of a spatula-shaped head part. If
outlet orifices are provided only in a part of the head part, then
the applicator material need not necessarily be provided over the
entire outer surface of the head part but can be restricted to
this partial zone or to an area around this partial zone.
Several options are open, too, with regard to the
location of the outlet orifices in relation to the applicator
material. In the case of an applica-tor material which takes the
form of a covering of woven material, knitted material, foam or
fleece material, the outlet orifices can be disposed beneath the
covering so that they are invisible. This first possibility has
the advantage that during use the applicator material is
constantly "permeated" by fresh composition, so that no residues
of old and tired composition can accumulate in the applicator
material. The outlet orifices can however also be visible from
outside in that the applicator material is disposed longside or
around the outlet orifices. This further possibility may be
considered for application materials in the form of brush hairs
or flocking, but it may also be used in the case of a fabric
covering and has the advantage that the user can also visually
monitor the amount of emerging composition and is therefore not

left to depend on controlling it by the lifting movement of the
lifting mechanism. Which of these possibilities is preferable
will depend upon the particular application.
The device according to the invention is suitable not
only for stable-form compositions of a pasty-wax-like nature
(such as lipsticks or the like) or of a harder consistency (such
as eyebrow pencils, kohl pencils, compressed powder and the like)
which have already been available in stick or pencil form, but
also for creamy-soft compositions which are not stable in form.
Thus, for the first time, the invention has made it possible also
for creamy-soft compositions such as eye shadow, rouge and the
like to be offered in stick form. When they are pressed against
the head part as the lifting mechanism is operated, these creamy-
soft compositions can perform a flowing motion so that the column
of cosmetic composition which is disposed inside the sleeve is
- independent of the type and disposition of outlet orifices in the
head part. The same applies at least, too, to some of the pasty~x-
like compositions. With harder compositions on the other hand,
which can be applied to a flat area only with difficulty and
which may be rather brittle, it is generally necessary, but at
least expedient, for the outlet orifices to have a sufficient
cross-section and for the radius of the column of cosmetic
composition to be no greater than the maximum radial distance of
the outlet orifices from the sleeve axis.
In terms of lifting mechanism, numerous constructions
are known in the cosmetics industry and in principle they are
all suitable for the device according to the invention. Preferred

~ Ol 71600-4
among them are the simpler constructions, since the column of
cosmetic compositionJ in contrast for instance to the known
lipsticks r only needs to be raised and not to be lowered again.
For compositions of a harder nature, it is expedient to use a
twist-and-lift mechanism and possibly
,
~' ~
.
, :
. : . ~

to construct the inner edge of the outlet orifices as a scraper in order
to Eacilitate detachment of composition from the column. For the more
readily flowable compositions, however, a push-, pull- or pressure-operated feed
mechanism with no twisting motion is adequate and therefore with these
compositions the sleeve no longer requires to have conventional circular
cross-section. Instead, an elliptical or otherwise flattened cross-section
may be provided. Furthermore, such feed mechanism in conjunction with the
applicator head according to the invention makes it also possible to use one
and the same 'pencil' for applying two different cosmetics, for example
cosmetics of a difEerent colour, in that the slaeve may be divided by a
central wall into two longitudinally extending chambers, each chamber having
its own feed mechanism and having associated with it one half of the
applicator head. This option has not been available in the past, either.
The invention will be explained in greater detail hereinafter with
reference to a few basic embodiments and their alternatives, which are
illustrated in the accompanying drawings, in which:

forms of another version of the embodiment according to Figure 3;
Figure ~ is a longitudinal section -through a further
modified form oE the embodiment shown in Figure 3;
Figure 7 shows a longitudinal section through a third
embodiment of the invention, and
Figures 8A and 8B are plan and side views respectively
of a fourth embodiment of the invention.
In the case of the embodiment shown in Figure 1, a
sleeve 1 is provided with an applicator head 2 having a cone-
shaped head part 4 which, like a cap, constitutes the outer means
of closing the sleeve. The head part 4 may be integral with the
sleeve or may be a separate body connected by a base ring 3 to the
sleeve 1, e.g. by screwing or gluing. The sleeve 1 is thereby
provided with a conventional lifting mechanism and contains a
cosmetic composition which is not shown in detail in Figure 1.
The cap 4 consists of synthetic plastics material or metal and
has outlet orifices 5. Furthermore, the cap 4 is provided with
a covering 7 of for instance gauze or a foam material. This
covering 7 which is only shown by broken lines in Fiyure 1, covers
the entire outer surface of the cap 4 and is sealed by the base
ring 3 against the bottom rim of the cap.
Figure 1 shows the outlet orifices 5 as slits, in two
alternative configurations. In the left-hand half (Figure lL)
are relatively short slits 5' disposed only in the region close to
the tip of the cap 4, while in the right-hand half (Figure lR),
long slits 5" extend over virtually the entire length of the cap.
s ~
, ,
ZS90~L0
71600-~
These two alternatives can be provided singly in that the cap 4 is
constructed only with short slits 5' or only with long slits 5".
Equally well, both versions may be provided on one and the same
cap, in that the cap is provided on one half with short and on
the opposite half with long slits.
Further possibilities which are not shown in the
drawings reside in providing not only the slits 5' or 5" but also
a central orific~ directly at the point of the cap 4 in order to
achieve boosted delivery of cosmetic composition at the tip of the
cone. The slits can thereby extend to a point close to this
central orifice so that their upper ends are bridged by just a
narrow web. If the material of the cap 4 is stab}e enough, then
; the arrangement can also be such that the slits merge into the
central orifice at their top ends. Furthermore, it is not
necessary, as shown in Figure lR, for a plurality of long slits 5"
to be disposed in a staggered arrangement peripherally; instead,
it is possible to provide one slit which extends continuously from
the tip of the cap to its bottom rim.
For the rest, construction of the outlet orifices 5 is
not confined to the slit shape. Similarly, the outlet orifices
may also be circularly, angularly or irregularly shaped holes
disposed in a more or less even distribution over the cap 4. In
a further example, the cap 4 may be constructed as a grid in which
case, then, the intermediate spaces between the grid webs will
serve as outlet oriices. This offers a particularly large cross-
section of orifice and thus a correspondingly intense emergence
of cosmetic composition to the covering 7.

For flowable compositions, the disposition and
construction of the outlet orifices may be chosen solely accord~
ing to whether a more all over application (by means of the cone
surface) or a more linear application (by means of the tip of the
cone) will more predominantly constitute the norm or whether both
types of application will be required with equal frequency. For
harder compositions which are not readily flowable or which do
not flow at all, however, it is necessary also to take into
account the fact that the radius of the column of cosmetic
composition may not be any greater than the maximum radial
distance"a" between the outlet orifices 5 and the sleeve axis.
Furthermore, in this case the outlet orifices must be so disposed
that every area of the surface of the outer end of the column of
cosmetic composition wipes over an outlet orifice at least once
during one twist.
Figures 2A and 2B show two different embodiments of
outlet orifice 5 which are particularly suitable for harder
compositions, applied in conjunction with a twist-and-lift
mechanism. The apertures 5 according to Figure 2A do not extend
radially but in the direction of twist of the lifting mechanism
and obliquely through the walls of the cap 4, and in the case of
the orifices shown in Figure 2B, their rear edge 6 (in the
direction of rotation) protrudes into the interior of the cap 4
to act as a scraper. For such harder compositions, it is
expedient to dispose between the lifting mechanism and the column
of cosme-tic compositlon also a small thrust spring to prevent the
column (as the lifting mechanism is operated) being accidentally
i~ '

forced with excess pressure into the cap 4 and becoming damaged.
An example of a plug-shaped applicator head 12 which is
only partly provided with applicator material is shown in
longitudinal section in Figure 3A and in cross-section in Figure
3B. The applicator head 12 contains a head divided into two
parts divided into 14' and 14", of which the part 14" is a solid
body whereas the part 14' is provided with axially parallel
longitudinal slits 15 which cons'~itute the outlet orifices. Both
parts are connected to each other by a base ring 13 and possibly
10 also by an only diagrammatically indicated locking means 18, the
base ring 13 at the same time constituting the connection between
the applicator head and the sleeve 11. The part 14 is further-
more provided with a covering 17 of foam material or some corres-
ponding applicator material, its edges being rigidly clamped
between the part 14' and the base ring 13 or in the gap 19
between the parts 14' and 14".
The applicator head 12 is preferably designed Eor the
application of readily flowable compositions which it was not
possible previously to offer in stick form. The head part 14',
20 14" can be conical in shape but the construction may also be
such that both parts taper substantially only in the diraction
at right-angles to the gap 19, the part 14" being in addition
flattened (as shown in Figure 3A, Figure 3B) so that a more
spatula-like form is provided. The applicator head 12 can be
used for flat or linear application, as desired, in that the
applicator head is applied to the skin either in the tangential
plane X or in the tangential plane Y (Figure 3B~.

The slit-shape outlet orifices 15 accommodate a
relatively large amount of cosmetic composition and serve to hold
a measured quantity of composition so that the applicator material
can during application be constantly filled with fresh composition,
which means that application becomes particularly even and the
lifting mechanism has to be actuated less frequently. This effect
can, however, also be achieved with differently formed outlet
orifices, an example of which is shown in Figure 4. There, an
applicator head 22 is shown which has a one-piece comb-shaped head
part 24 which, as outlet orifices, has numerous groove-like
depressions 25 extending towards the tip of the cone and also an
additional central orifice 25' and covered completely by a cover-
ing 27 of foam or like material. In the same way as the head 12,
this applicator head 22 can be inserted by means of a base ring
into a sleeve, which is not shown in detail, and its operation
corresponds to that of the head 2 in Figure 1.
Figure 5 shows in a sectional view taken on the line
IIIB-IIIB in Figure 3A examples of a two-part head part with an
elliptical cross-section which can be used in conjunction with an
elliptical sleeve but which, with appropriate adaptation of the
base ring, not shown in detail, can also be suitable for round
sleeves. In Figure 5, as with Figure 1, two alternative forms are
combined into one drawing. The left-hand half 34' of the head
(Figure 5L) has longitudinally extending slit-shaped outlet
orifices 35' which correspond to the outlet orifices 15 in Figure
3 and which are so constructed that the supply of cosmetic
composition diminishes from the flatter centre of the head piece
- 15 ~ ,903L~
71600-4
half towards the two more intensely curved edges. In the right-
hand half 34" of the head (Figure 5R) there are outlet orifices
35" in the form of longitudinal channels, for example bores which
open out into the outer face of the head part hal 34". With
these longitudinal channels, the stock of cosmetic composition
held is all in all less than with the longitudinal slots. Each
of the two head part halves 34' and 34" is provided with a
covering 37' or 37ll of foam material or some corresponding
applicator material.
The head part halves 34' and 34" shown in Figure 5 can
be used to form applicator heads after the fashion of the head 12
described in Figure 3 in that either the head part half 34' or
the head part 34" is combined with a (not shown) second solidly
constructed head part half in the manner described with reference
to Figure 3. These possibilities are not shown in detail in the
drawings but can be derived from Figure 5 in that either the slots
35' and the covering 37' are omitted from the head part half 34'
or the lonyitudinal channels 35" and the covering 37" are omitted
from the head part half 34". Compared with the applicator head
20 12 according to Figure 3, such an elliptical applicator head offers
the advantage that flat zones with a very large radius of
curvature and on the other hand also with a very small radius of
curvature are
~'
created, Eacilitating both flat and also linear application of the
composition.
A two-part head part does however also open up what is fundamentally
a new option of using a single pencil-shaped applicator to apply two cosmetic
compositions which differ in colour and/or consistency. To achieve this, it is
necessary only to sub-divide the sleeve into two longitudinally extending
chambers by providing a central wall and by associating with each chamber a
respective lifting mechanism (which in this case is expediently constructed as
a push-, pull- or pressure-operated feed mechanism) and its own head part
half which is provided with outlet orifices. Figure 5 can also be regarded
as an example of such a possibility if it is assumed that the two head part
halves 34' and 34" are so inserted into a sleeve sub-divided into two
chambers that the head part half 34' belongs to one chamber while the head
part half 34" belongs to the other chamber. In this case, as already explained
with reference to Figure 3, the two head part halves can be comtected to
each other by a locking device 38 and inserted into the sleeve by means oE a base
ring, not shown in detail in the drawings, rather like the base ring 13 in
Figure 3A, the middle wall of the sleeve expediently extending as far as
into the gap 39 between the two head part halves, in order to ensure that the
cosmetic compositions disposed in the chambers in the sleeve can only emerge
through the head part half associated-with them.
In the case of an applicator head according to Figure 5 which
has a two-part head part for the application of two
: .
- 16 -
.
. : ,. :
,, '; . ~: - ,:'
- 17 -~59010
71600-4
different compositions, the middle areas of the head part halves
34' or 34" can apply each composition by itself, while in the
marginal zones of both halves, where the coverings 37' and 37"
meet, mixing effects can take place which permit of particularly
interesting cosmetic designs. However, should such mixed effects
be undesirable, then it is possible to insert into the gap 39 an
additional separating film 36 to prevent the two compositions
blending. Instead of a separating film 36, it is also possible
to use a somewhat broader solid intermediate part (not shown)
which fills the gap 39 and spaces somewhat farther apart the two
head parts 34' and 34". As such a solid intermediate part it is
possible also to use the centre wall through the sleeve if this
extends as far as the outer edge of the two head part halves which
are connected to each other. The elliptical shape shown in Figure
~ 5, in which the gap 39 extends in the direction of the long axis
; of the ellipse, is particularly advantageous for flat application
of the two compositions. If, however, a more linear application
has priority, then the gap 39 can also be disposed in the direction
of the short axis of the ellipse, so that the sharply curved
portions of the surface are shifted into the centre of the two
head part halves.
The construction of applicator head for applying two
different compositions, explained with reference to the example
shown in Figure 5, does not presume that the outlet orifices in
the two head part halves differ from each other in disposition
and cross-section of aperture. Differences of this type are
expedient if for example one composition is normally applied more
thinly or more rarely than the other composition. Then, too, the
: . :
- , :,
~;, ~, ,
- 18 ~ 1'~ S~ ~
71600-4
middle wall in the sleeve may be so disposea that the chamber
containing the composition which is to be applied more rarely has
a smaller capacity than the other chamber. In general, however,
it is preferable for the two head part halves to be constructed
identically to each other and also to make the two chambers in
the sleeve the same size as each other. For the rest~ the two
head part halves do not need to be elliptical but may also adopt
any other shape and may for example be conically round or have a
polygonal cross-section with outwardly shaped edge zones. Two-
part caps are also possible although technically they are somewhatmore difficult to produce.
In the examples of embodiment which have been described
; thus far, the applicator material is in each case a covering of a
woven material, knitted material, foam or fleece material and the
outlet orifices are in each case underneath this covering. It is
however equally possible for the outlet orifices to be so disposed
that they are not covered by the applicator material. An example
of this is shown in Figure 6. The applicator head 42 shown in that
drawing and inserted by a base ring 43 into a sleeve 41 has a solid
head part 44 and is provided with a fabric coverin~ 47. In the
head part 44 is a port 46 which opens out into a somewhat widened
outlet orifice 45. The covering 47 is provided with a cut-out, in
other words has a hole 48 in it, in the region of the outlet
orifice 45, so that the quantity of cosmetic composition emerging
from the outlet orifice 45 and distributed in the covering 47
during use is visible and can be monitored from outside. Such a
disposition of the outlet orifice is naturally also possible with
. :
.,
..
- 19 - ~S~O~
71600-4
other embodiments of head part, for example in the case of the
two-part head 12 shown in Figure 3 or in the case of a head part
after the fashion of Figure 5 for applying two different
compositions.
Figure 7 shows an example of embodiment of externally
visible outlet orifice which is not enclosed on all sides by
applicator material but which is situated in front of the appli-
cator material in the direction of flow of the cosmetic
composition. The applicator head 52 according to Figure 7 has a
plug-like base 53 by which it is inserted into a sleeve 51 and
has an elongated head part 54 which extends in the axial direction
of the sleeve 51 or at an angle thereto and which may be
constructed for example as a rod or as a narrow spatula. In the
base part 53 there is a port 56 which opens out inko an outlet
orifice at the start of the head part 54. The head part 54 is
covered with fine brush hairs or is provided with a velvet like
flocking but it may also carry a covering of one o~ the fabric
materials.
An applicator material in the form of a velvet-like
flocking or a covering of brush hairs may also be used in all the
other embodiments of the applicator head instead of using a cover-
ing of one of the fabric materials and thus it is possible also
to provide further novel opportunities for the application of
cosmetic compositions. As an example, Figure 8 shows an
applicator head 62 which makes it possible to apply hard compounds
such as for example compressed powder, directly by means of a
brush. For this purpose, the applicator head 62 is inserted into
a sleeve 61 which has a lift-and-twist mechanism and has a head
~?~

71600-4
part 64 in the form of a flat or slightly bulbous cap which has
a slit-like outlet orifice 65 and brush hairs 67 to serve as an
applicator material. The slit 65 extends over the entire diameter
of the cap 64 and its rear edge zones (viewed in the direction of
twist) are expediently constructed as scrapers after the fashion
shown in Figure 2B, so that fine particles emerge from the slit,
pass between the brush hairs and can then be brushed directly onto
the skin. As shown, the brush hairs may all be of equal length or
alternatively the length of the brush hairs may increase from the
outside towards the centre so that a point is produced. The
applicator head 62 can be used equally well for applying soft
flowable compositions and in such a case it may be expedient,
instead of a slit, to distribute a plurality of small outlet
orifices in the cap 62 or to provide a round central orifice in
the cap.
It will be appreciated that the afore-described examples
can constitute only a selection of the numerous possibilities
which exist with regard to practical execution of the device
according to the invention and that further modifications of these
examples, such as for example different shapes and outer contours
of head part, different configurations of outlet orifices and
other dispositions and constructions of applicator material are
readily discernible and belong within the framework of the
invention. Therefore, the invention is not limited to the
examples which have been described.
