DETAILED DESCRIPTION OF THE INVENTION
[0009] Figure 1 represents an applicator unit 1 for a lip product 2 comprising a receptacle
3 for said product, notably for a cosmetic for the lips such as a more or less viscous
lip colored pasty product. The receptacle 3 comprises a neck 4 on which an applicator
device 5 is removably mounted.
[0010] In the represented embodiment, the applicator device 5 comprises a stem 6 carrying
on both sides an applicator body 7 and a cap 8 for the receptacle 3 which is disposed
opposite to said applicator body. Both the cap 8 and the neck 4 are threaded in order
to permit the mounting of the applicator device 5 onto the receptacle 3 to put the
applicator body 7 in contact with the product 2 into said receptacle.
[0011] The applicator unit 1 further comprises a wiper 9 which is mounted in the neck 4,
said wiper being able to wipe off excess product when removing the applicator device
5 from the receptacle 3. The wiper 9 has a body 10 presenting a outer surface fitted
in the neck 4, said body being surmounted by a annular exterior edge 11 adjacent to
a sealing ring 12 which cooperates within the neck 4 for the mounting of said wiper
onto the recipient 3.
[0012] At the bottom of its body 10, the wiper 9 has a soft wiping rim 13 extending inwardly,
said rim defining therein a central opening 14 in which the applicator device 5 is
able to slide upon removing. In one example, the wiper 9 is manufactured by molding
of a soft plastic material such silicon, butyl or nitrile rubber material.
[0013] Thus, after removing the applicator device 5, a sample of product is disposed onto
the applicator body 7, said sample being then possibly applied on the lips by brushing
said body onto them. To improve the comfort of said brushing, the applicator body
7 can be manufactured by molding of a soft plastic material. According to embodiments,
at least a portion of the outer surface of the applicator body 7 can be coated with
fibers and/or longitudinal ribs can be formed on at least a portion of said outer
surface.
[0014] As represented, the stem 6 is surmounted by a one piece applicator body 7 comprising
a proximal part associated with the stem 6 and a distal part 15 opposite from said
proximal part in a longitudinal direction. Each one of the distal 15 and proximal
part presents an outer surface to brush on the lips in order to apply the sample.
In the represented embodiment, the proximal part presents a base 16 which is inserted
in the stem 6 to associate the applicator body 7 to said stem.
[0015] In the application body 7, the distal 15 and proximal parts are linked by a bridge
17 formed in recess in said applicator body, the outer dimension of said bridge being
then smaller than both the outer dimensions of the distal 15 and proximal parts. In
particular, the bridge 17 forms a groove around it, said groove being disposed between
the distal 15 and the proximal part.
[0016] The distal part 15 comprises a rounded geometry having an outer diameter, notably
the geometry of said distal part can be spherical, eventually slightly deformed. The
proximal part comprises at least a protruding zone having an outer diameter which
is bigger than the outer diameter of the distal part 15. Furthermore, the dimension
of the central opening 14 of the wiper 9 is comprised between the outer diameter of
the distal part 15 and the outer dimension of the protruding zone in order to wipe
off said protruding zone but not said distal part.
[0017] Thus, due to its small diameter, the rounded distal part 15 permits to provide a
great precision for the application of the sample disposed on it and the difference
between the outer dimensions of the distal 15 and proximal parts permits to improve
the volume of the sample. It is then possible to combine the disposition of a great
quantity of product on the lips with the finesse of the outlines of the application
of said product onto the lips.
[0018] Product is also sampled around the bridge 17 to form a kind of reservoir for the
sample. In addition, the bridge 17 permits elastic displacements of the distal part
15 as regards the proximal part to improve the comfort and provide a very satisfactory
massage effect of the lips. In particular, the elastic displacements provide a bending
of the distal part 15 upon leaning it on the lips.
[0019] Those effects can be achieved with a bridge 17 presenting a longitudinal dimension
which is bigger than 10% of the outer diameter of the distal part 15 and/or an outer
dimension which is smaller than 60% of said outer diameter.
[0020] Furthermore, the bridge 17 can presents an elliptical transversal section to provide
a differential effort to bend the distal part 15 in function of the position of the
support of said distal part on the lips. Thus, the user can rotate the applicator
device, by means of the cap 8, to obtain the desired bending effect, without changing
the application surface since the distal part 15 is rounded.
[0021] In addition, the softness of the material of the applicator body 7 can be chosen
according to the bending effect desired, as well as to conserve a sufficient longitudinal
rigidity of said applicator body in order to keep the precision of the application,
notably of the outlines by means of the distal part 15. As examples, thermoplastic
polyester-polyurethane or thermoplastic ethylene-methacrylic acid copolymer are suitable
to manufacture the applicator body 7.
[0022] The proximal part can comprise geometries, notably rounded geometries, linked by
bridges formed in recess in the applicator body 7, the outer dimension of said geometries
decreasing from the stem to the distal part. In this embodiment, each bridge forms
a reservoir for the sample and a flexibility area between the geometries. In addition,
the application of the sample can then be done by either one of said geometries according
to the wishes of the user. According to figure 6a, the proximal part comprises two
ovoid shaped geometries 18a, 18b linked by a bridge 19 formed in recess in the applicator
body 7.
[0023] In relation with figures 1 and 2, we describe below an applicator body 7 comprising
three successive spherical geometries 15, 20, 21 linked by two bridges 17, 22, the
outer diameter of said geometries decreasing from the stem 6 to the distal part 15.
As shown on figures 2a and 2b, each bridge 17, 22 presents an elliptical transversal
section, the dimension of the proximal bridge 22 being bigger than the dimension of
the distal bridge 17.
[0024] As a numerical example, the main dimensions of the represented application body can
be:
- outer diameter of the proximal geometry 21: 5.0 mm;
- dimensions of the proximal bridge 22: 2.0 mm x 1.2 mm x 0.4 mm;
- outer diameter of the central geometry 20: 3.9 mm;
- dimensions of the distal bridge 17: 1.4 mm x 1.0 mm x 0.4 mm;
- outer diameter of the distal geometry 15: 2.9 mm.
[0025] This applicator body 7 can be used in combination with a wiper 9 as represented on
figures 3, wherein the wiping rim 13 has a serrated geometry comprising teeth 23 spaced
by holes 24. In this embodiment, the central opening 14 comprises two dimensions for
the wiping: the outer dimension D of the teeth 23 and the inner dimension d of said
teeth, said outer dimension being comprised between the outer diameter of the distal
part 15 and the outer diameter of the proximal geometry 21 in order to wipe off said
proximal geometry. In the above numerical example, the outer diameter D can be 4.4
mm and the inner diameter d 3.7 mm.
[0026] In relation with figures 4 and 5, the applicator body 7 first gets out the product
2 with a quantity of product around it (figure 4a). As the stem 6 also dips into the
product 2, the dimension of the central opening 14 is smaller than the outer dimension
of the stem 6 in order to completely wipe off the product 2 from said stem (figure
5g). In addition, the outer dimension of the stem 6 is bigger than the outer diameter
of the distal part 15 and similar to the outer dimension of the proximal geometry
21.
[0027] On figure 4b, as for the stem 6, the proximal geometry 21 has been completely wiped
off (figure 5f) since its outer diameter is greater than the outer dimension D of
the teeth 23, notably said outer dimension and said outer diameter can be similar,
that is to say different for less than 10%. A sample of product is not wiped off around
the proximal bridge 22 (figure 5e) in order to provide a serrated layer 25 of product
to apply on the lips.
[0028] In addition, the inner dimension d of the teeth 23 is similar to the outer diameter
of the central geometry 20 in order to wipe off partially said central geometry (figure
5d). In particular, upon sliding of the central geometry 20 into the wiping rim 13,
ribs 26 of product are disposed around the central geometry 20 through the spaces
24 formed between the teeth 23.
[0029] On figure 4c, a serrated layer 27 of product is disposed around the distal bridge
17 (figure 5c) and around the distal geometry 15 which is not wiped since its diameter
is smaller than the inner diameter d of the teeth 23 (figure 5b). Thus, as shown on
figures 4d and 5, a sample of product is disposed around the applicator body 7 in
order to be applied onto the lips.
[0030] In relation with figures 6b to 6e, the application body 7 can have a proximal part
comprising, from the stem 6 to the bridge 17, a diverging zone, a central zone and
a converging zone, the protruding zone being formed on the central zone. Indeed, those
embodiments also permit to combine the sampling of a great quantity of product with
the precision of the application of said sample on the lips.
[0031] On figures 6b, 6c and 6e, the proximal part presents an ovoid shaped geometry 28.
The outer surface of this geometry can present edges as shown on figure 6b, can be
slick as shown on figure 6e or can present longitudinal ribs as shown on figure 6c.
[0032] According to figure 6d, the proximal part can also present a diverging conical zone
29 and a converging conical zone 30, the central zone being formed on the junction
base 31 of those conical zones which presents then the biggest outer dimension.
