DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to the drawings, Figs. 1 to 5
show a first embodiment in which reference numeral 1
designates a flask or another container the upper portion
of which has to be closed by a capsule 2.
In the present embodiment, the capsule 2 has a
generally cylindrical shape, but the capsule 2 could have
any other desired shape~
The flask 1 has a narrow portion or neck 3 at
one end, and includes also interlocking elements 4, for
example recesses as shown, or a groove, or still screw
threads, for complementary interlocking portions 5 formed
by an envelope 6 of the capsule 2. The envelope 6 has a
JJ:~ 3
. .
t~
~3~
top portion having a bottom 7 in the underneath portion
of which is defined a guiding member 8 forming a passage
9 with the underneath portion of the bottom 7.
The underneath portion of the guiding member 8
includes a wall 10 formed with at least one port 11.
The guiding member 8 is extended below the wall
10 by an annular ~kirt 12 adapted for penetrating in the
neck 3 so as to seal the flask 1 with respect to the
capsule 2. The guiding member 8 also forms an opened
ring 13 concentric to the skirt 12, for partially
surrounding the outside of the neck 3.
In addition to the foregoing disclosure, the
envelope 6 defines, in its side wall, a hole 14 (Fig. 4)
bounded by guiding members 15.
The passage 9 is used for housing a drawer 16
defining a duct 17 opening to the outside at 17a and
opening also, via a hole 17b, towards the wall 10 of the
guiding member B.
The drawer 16 forms, at its end which is
opposite the opening 17a, a push-piece 18 which is
axially guided in the guiding members 15.
Advantageously, the push-piece 18 includes a
resilient element 19 which can be formed of a tongue made
integral with the drawer 16 and push-piece 18 assembly.
As there is shown in the drawings, the
resilient element 19 bears against the flask 1 in order
to maintain the push-piece 18 outside the envelope 6 in
a rest position of non-use, the duct 17 having then its
JJ:~ 4
~
~3~355~31
opening 17b offset with respect to the port 11 formed in
the wall 10 of the envelope. On the other hand, the
opening 17a of the duct 17 is flush with the outside o~
the envelope 6.
- 5 In order to use the produc:t contained in the
flask 1, the only thing to do is to ~exert a pressure on
the push-piece 18, thereby moving the drawer 16 from the
position shown in Fig. 2 to that of Fig. 3. In this
manner, the opening 17b will come in register with the
port 11, and the product contained in the flask 1 can
flow out, either by exerting a pressure on the flask 1 if
the flask 1 is flexible, or by inclining it if the flask
1 is rigid.
In order to prevent the drawer 16 from falling
out, the drawer 16 is provided for example on its
underneath portion with a protrusion 20 forming an
abutment member, the protrusion 20 coming to bear against
the opened ring 13 when the drawer 16 is in a closed
position as shown in Fig. 2.
The envelope 6 as well as the drawer 16,
forming the two only parts of the capsule, are
manufactured preferably from a thermoplastic material by
injection moulding. For making the drawer 16, a flexible
and resilient material is chosen which enables to form
the resilient elements 19 at a low cost price, and
enables also the protrusion 20 to be resiliently deformed
when placing the drawer 16 in position.

Fig. 6 shows an alternative embodiment
according to which the bottom 7 of the envelope 6 forms,
on its top portion, a hollow mouth-piece 21. In this
embodiment, the drawer 16a has the shape of a single
plate in which there is formed thè opening 17b which can
; be brought in register with the port :ll. Other reference
numbers designate same members as those described in
reference with Figs. 2 - 5, and the operation thereof is
similar.
Since the drawer 16a is made of a single plate
which does not have a resiliency comparable to that of
the hollow drawer 16 oE Figs. 2 - 5, it is advantageous,
for ensuring a good tightness between the drawer and the
wall 10, to provide on the wall 10 an annular protrusion
or pad 22 (see Fig. 7), the funtion of which is to act
as a seal while slightly spacing away the drawer from top
of the wall 10.
Further to improving tightness, the annular
protrusion or pad 22 aids in positioning the drawer 16a
and, in particular, aids to a resilient deformation of
the abutment ~orming protrusion 20.
Figs. 8 - 10 show another embodiment according
to which the drawer 16a, placed in the passage 9 of the
slide member 8, is connected as previously to a push-
piece 18a. The push-piece 18a includes however two wings
23, 2~ guided on flats 25, 26 of the envelope 6. The
wings 23, 24 are advantageously serrated for facilitating
JJ:r~ ~
~' ~
- ~3~3~
the grasping thereof. This embodiment enables to
eliminate the resilient element 19 of Figs. 2 - 7.
In Fig. 8, the bottom 7 of the envelope 6 is
formed with a hole 27 with which the opening 17b of the
drawer 16 can be brought in register.
Obviously, the push-pieca L8a formed with the
wings 23, 24 as just described above can also be used in
a similar manner in the embodiments of Figs. 6 - 7 and of
Figs. 1 - 5.
Figs. 11 - 13 show a development of the
invention, as well as an alternative embodiment. In
Figs. 11 - 13, the envelope 6 forms, above the bottom 7,
side ~langes 28 for the support of a distributor cylinder
29. The cylinder 29 can be fixed, for example by a snap-
in action of end stubs 30 carried by the cylinder 29,
inside notches 31 o~ the flanges 28.
The bottom 7 is formed, as in Fig. 8, with a
hole 27 which can be brought in register with the hole
17b of the drawer which is here shown at 16~. The drawer
16~ is guided by a slide member 8 which is similar as in
the embodiment of the preceding figures. The drawer 16
can be operated by a push-piece 32 formed with wings 32a,
32b advantageously provided with vertical serrations, a
grained appearance or prints for housing the user's
fingers. The drawer 16~ may also be activated by any one
of the means described in the above discussed
embodiments.

It is advantageous, in the embodiment of Fig.
11, to further provide a cap 33 in order to cover both
- the whole of capsule 2 and the distributor aylinder 29
~hat it includes, thereby ensuring a protec~ion of the
distributor cylinder 29 which is, on the other hand,
integral with the capsule ~.
Moreoever, the cap 33 provides a locking of the
drawer 161 in the closing position.
Fig. 13 shows that ~he protrusion 20, which
forms an abutment, can be provided at the end of each of
two lugs 34 of the drawer 16l, thereby facilitating a
setting in position o~ the drawer 161 due to the
flexibility of the lugs 34.
As in the foregoing disclosure, same reference
numerals designate same members as described with
reference to the preceding figures.
Figs. 14 and 15 still show another embodiment
according to which the passage 9 of the slide member 8
: communicates, as previously, with the inside of the flask
1 via the port 11 formed in the wall 10. The port 11 is
in alignment with the hole 27 of the bottom 7 of the
capsule. In this altexnative embodiment, the drawer 16b
~ is made of a plane hlade articulated via pivot member~
:~ 35, 36 inside the slide member 8.
A hole 17b is formed in the drawer 16b in the
same manner as in the drawer of Figs. 6 to 12 so that the
hole 17b can be brought in register with the hole 27 and
port 11.
.~ .
~L3~3~
~t rest, the drawer 16b, which is of a smaller
length than the passage 9, is placed in such manner that
the hole 17b is offset with respect to the hvle 27 and to
~ the port 11, so that the capsule iS closed.
; 5 As shown in the drawings, the drawer 16b
includes advantageously a resilient element l9a
; constituted for example of a lug formed opposite a notch 370
At rest, the lug l9a bears against the lateral
side of the slide member 8, and thereby maintains the
drawer 16b so that it closes the port ll and hole 27.
In order to operate it, the drawer 16b forms an
operating lug 38 protruding beyond the capsule.
A mask 39 is also formed by the drawer 16b so as
to close the passa~e 9.
For avoiding any rotary movement of the capsule
2 during operation of the drawer 16b, it i5 advantageous
that the capsule 2 includes a key 40 entering a qroove 41
of the flask 1.
The invention is not limited to th~ embodiments
shown and described in detail since various modifications
thereof can be carried out thereto without departing from
its scope a shown in the appendant claims. In
particular, the distributor cylinder 29 can be rep~aced
by other applicator means, for example a porous block,
balls or other members~ Likewise, the pivoting drawer of
Figs. 14 and 15 can form a duct 17 similar to that
described with reference to Figs. 1 to 5, this duct 17

opening in the lug 38. Moreover, the passage 9 of Figs.
14 and 15 can be of a circular shape, the drawer being,
in that case, made of a disc.
The members described in the above disclosure
make that, in all the embodiments, means are provided for
maintaining the capsule in a closed state when it is in a
position of non-use.
