Description

Applicator for applying liquid cosmetics

The present invention relates to an applicator for applying liquid cosmetics.

The expression "cosmetics" is understood to mean any product as defined in the European Parliament and Council Regulation (EC) No 1223/2009 of 30 November 2009 for cosmetics.

The applicator is more specifically intended to apply cosmetics to human keratinous surfaces such as skin, lips, or nails. The cosmetic product may in particular be a care product or a makeup product, for example a liquid foundation, nail polish, lipstick, cream, oil, hair care product and the like.

Generally, the applicator includes an applicator member mounted on a gripping member, the applicator member defining an application surface intended to contact the user's body surface.

The gripping member may in particular be the cap of the reservoir, wherein the applicator member is filled with cosmetics from the outside or from the reservoir itself (eg a pen applicator), and the applicator member is supplied with cosmetics from the inside.

The applicator member is mounted on the gripping member through a fastening and fastening element comprising a housing for receiving and retaining the fastening or bottom portion of the applicator member.

The fastening element can be attached to the gripping member or can be manufactured integrally therewith.

In particular, the applicator member can be a foam or a deformable, particularly compressible elastomeric applicator member.

As examples, documents FR2962890, FR2814651, and FR2832297 in which such applicators are described can be cited.

Document FR2962890, in particular FIG. 2, describes an applicator comprising a gripping portion on which the coating film is mounted. To this end, the gripping portion has a mounting skirt defining a housing for receiving the fastening portion of the membrane. The fastening of the membrane is mounted in a fixed manner, for example by adhesively bonding or welding to the inner or outer surface of the mounting skirt, or in a detachable manner, for example by frictional fitting, snap-fastening, or interference fitting Stay on the skirt.

Document FR2814651 describes an application element that is fastened to a cover through a mounting skirt, the application element being adhesively bonded, welded, or snap-fastened in the mounting skirt.

Document FR2832297 describes an applicator comprising a reservoir for forming the gripping member and supporting the intermediate element, the applicator member being received and held inside.

To this end, the intermediate element defines an inner cylindrical housing with side walls and a substantially flat transverse wall forming the bottom of the housing.

The housing of the intermediate element communicates with the inside of the reservoir through a flow path through a hollow shaft extending along the longitudinal axis of the housing.

The applicator member is mounted around the hollow shaft inside the housing. The applicator member is in the form of a block of porous material, typically a foam, at least a portion of which is elastically compressible.

The applicator member is fastened to the inside of the housing of the intermediate element, in particular in a detachable manner, by adhesive bonding or snap-fastening.

It has been found that the system for mounting the applicator member is not completely satisfactory.

In particular, it has been found that when the applicator member is adhesively bonded to the mounting element, the adhesive tends to decompose upon contact with the cosmetic or some of the compound (especially when the cosmetic contains a volatile compound). After a period of time, fixing of the applicator member is no longer optimally guaranteed.

In addition, the cosmetic applicator undergoes numerous forward and backward lateral movements, which can result in wear and tear of the fastener.

Therefore, as mentioned in the documents cited above, it is generally preferred to use fastening by mechanical holding.

However, such mechanical fastening can also prove to be insufficient, and there is a need for an improved mechanical fastening scheme that allows the applicator member to withstand particularly lateral or tensile coating forces.

In addition, mechanical fastening methods are generally relatively complex, and there is a need for a simpler fastening system that makes assembly easier.

The present invention seeks to achieve some or all of these purposes, and for this purpose, as an applicator for applying cosmetics, an applicator defining a coating surface in the form of a block of deformable material and intended to contact the user's body surface A member, wherein the applicator member is on the gripping member through at least one fastening and fastening system comprising at least one peripheral skirt defining a housing for receiving a mounting bottom of the applicator member, together with an end wall. In the applicator, which is mounted on, the fastening and fastening system includes at least one complementary clamping ring capable of compressing a portion of the mounting bottom located at a non-zero distance from the base surface of the mounting bottom. , The base surface is fixed and fastened sheath when the applicator member is placed in the housing of the fastened and fastened system Orienting towards the end wall of the clamping ring, the clamping ring comprises at least one clip-fastening means capable of interlocking with at least one complementary clip-fastening means of the surrounding skirt of the fastening and fastening system. do.

Thus, by providing an additional clamping ring that can be mounted on the skirt by clip-fastening, assembly becomes much easier, and the ring supporting the applicator member only needs to be introduced into the housing until it is clip-fastened to the skirt. .

The clamping ring can be made detachably so that the applicator member can be replaced with the same, eg a new or different applicator member.

In addition, the clamping ring compresses only a portion of the mounting bottom at a distance from the base of the mounting bottom of the applicator member.

As a result, the mounting bottom has a compressed section with a reduced cross section and an uncompressed or less compressed base section with a larger cross section. The uncompressed or less compressed base portion has a wider cross section that resists the extraction motion with the longitudinal component of the applicator member out of the ring, including lateral movement motion, thereby securing and retaining the applicator member. It contributes considerably.

In addition, compression of a portion of the mounting bottom of the applicator member increases the friction between the mounting bottom and the ring, which also contributes to overall retention.

According to a first variant embodiment, the applicator member is made of a foam, preferably a block of foam.

According to a second variant embodiment, the applicator member is made of an elastomeric material, preferably a block of elastomer. In particular, it is also possible to use an applicator member made of, for example, silicone.

Depending on the supply of cosmetics and the desired product load on the applicator member, the applicator member may have some open pores if necessary. Alternatively, if the product is not desired to diffuse into or through the applicator member, the material used may or may not have pores.

In an advantageously complementary manner, the applicator member has an application surface that is at least partially flocked or even fully planted.

Advantageously, the level of compression is at least 10%, preferably at least 20%, or even at least 30% relative to the cross section of the applicator member in an uncompressed or less compressed state in the housing. In order to maintain good capillary development of the applicator member and good comfort during application, it is appropriate not to overcompress the bottom of the applicator member. To this end, the compression level is preferably less than 40%, or even less than 35%.

The level of compression can vary depending on the compressibility of the material of the applicator member.

Specifically, the level of compression, in particular when introduced into the housing for receiving the mounting bottom of the applicator member and clip-fastened therein, causes a reduction in the cross-section of the housing and thus a clamping ring resulting in partial compression of the applicator member. Depends on the thickness of

In an advantageously complementary manner, the end wall of the fastening and fastening system comprises at least one tooth that can enter the base surface of the bottom of the applicator member. The teeth are particularly helpful in fastening the applicator member by limiting lateral motion during rotation.

In an advantageously complementary manner, the clamping ring preferably has an end intended to be oriented towards the end wall of the fastening and fastening system, the end being at least partially with a complementary slot around the mounting bottom of the applicator member. It has a radial shoulder that is at least partially engageable.

The presence of such shoulders that can fit into corresponding slots formed in the mounting bottom of the applicator member makes it possible to further increase the fastening and fastening of the applicator member. This is because the shoulder entering the slot acts as a stop to prevent any longitudinal movement of the applicator member. The stop also limits the lateral movement.

Preferably, the peripheral radial shoulder has a surface intended to be oriented towards the end wall of the fastening and fastening system, and at least one engaging tooth that can enter a corresponding surface of the peripheral slot of the applicator member.

With respect to the end wall, the teeth help limit any lateral movement of the applicator member in the housing, in particular any rotation. In combination with teeth on the end wall, fixation is particularly effective.

According to a preferred embodiment, the slot of the mounting bottom of the applicator member is located approximately in the middle of the mounting bottom. Preferably, the slot is located between 30% and 60% of the height of the mounting bottom relative to the base.

In a complementary manner, the end wall of the fastening and fastening system extends at least partially through the clamping ring substantially perpendicular to the end wall and is capable of entering at least one, in particular, a corresponding cavity of the mounting bottom of the applicator member. It has a central spike.

Therefore, in particular by providing a central spike, the compression and clamping of the applicator member in the ring is further increased.

Preferably, the spike extends through the entire length of the clamping ring and passes completely through it.

Preferably, the spikes on the end walls protrude from the skirt of the fastening and fastening system. Such features help limit the amplitude of movement of the applicator member.

Note that when the cosmetic product is supplied from the inside of the applicator member, the spike can be hollow and can act as a cannula for supplying the product.

Advantageously, the clamping ring extends over approximately half the height of the mounting bottom of the applicator member. Preferably, the clamping ring extends over at least 40% of the height of the mounting bottom. Preferably, the clamping ring extends up to 90% of the height of the mounting bottom.

Thereby, to ensure good maintenance of the applicator member, it is possible to have a relatively large compressed portion of the mounting bottom, while also maintaining a relatively large uncompressed or less compressed portion of the mounting bottom.

The invention also relates to a packaging and application assembly of a liquid cosmetic, comprising both a body forming a reservoir intended to contain the cosmetic product (P) to be applied, and an applicator according to the invention.

According to a first embodiment, the gripping member forms a closing cap for the reservoir, wherein the applicator closes the reservoir with the gripping member closing the reservoir and the gripping member separated from the reservoir and the storage location where the applicator member is disposed inside the reservoir. The applicator member can move between the application locations extracted from the reservoir.

According to the second embodiment, the gripping member is connected to the reservoir in a non-removable manner, wherein the applicator member is disposed in the fluid reservoir in communication with the interior space of the reservoir containing cosmetics.

The present invention will be better understood by reading the following detailed description with reference to the accompanying drawings.
1 is a schematic longitudinal sectional view of a packaging and application assembly with an applicator according to the present invention.
FIG. 2 is a schematic longitudinal cross-sectional view of the applicator member provided in the assembly of FIG. 1.
3 is a schematic longitudinal sectional view of a clamping ring for mounting and fastening the applicator member of FIG. 1;
4 is a schematic plan view of the ring of FIG. 3.

The assembly (1) is an applicator (4) comprising a body (2) forming a reservoir (3) containing the cosmetic product (P) to be applied, and an applicator member (5) mounted on the gripping member (41). It includes.

The body 2 has a free upper edge 21 defining an opening 22 of the reservoir 3. More specifically, the opening 22 is located at the free upper end of the neck 24 of the body 2.

The body 2 has rotational symmetry. The opening 22 has a circular cross section. Of course, other shapes may be considered.

In the opening 22, the body 2 is provided with a housing 7 capable of receiving the applicator member 5, which housing is at least partially by a separating wall 8 from the reservoir 3 It is limited to.

The separation wall 8 has at least one through-orifice 9 in direct fluid communication with the reservoir 3.

The dividing wall 8 can be attached to the reservoir 3 as shown, or can be made integral with the body of the reservoir by molding.

In this case, the separation wall 8 is carried by a ring 60 overlying the opening 22.

The ring 60 can be mounted on the body 2 by any means, in particular clip-fastening or adhesive bonding. It may or may not be removable.

In this case, the ring 60 may engage the neck 24.

To this end, the ring 60 includes an outer peripheral wall 61 and an inner peripheral wall 62 that together form a mounting skirt.

The mounting skirt also provides leakage protection for the product.

In the upper part, the applicator 4 comprises a gripping member 41 on which the applicator member 5 is mounted.

The gripping member 41 forms a lid, and engages with the upper peripheral wall 63 of the ring 60 in a detachable manner, so that the reservoir 3 can be closed in a leak-proof manner. More specifically, the peripheral wall 63 of the ring 60 carries an external thread that can engage the complementary internal thread of the gripping member 41.

When not in use and when the gripping member 41 is screwed onto the ring 60, the applicator member 5 is received in the housing 7 (FIG. 1).

Therefore, in the applicator 4, the gripping member 41 closes the reservoir 3 and the storage position where the applicator member 5 is disposed inside the reservoir and the gripping member 41 are separated from the reservoir 3 The applicator member 5 can be moved between the application positions extracted from the reservoir 3.

The applicator member 5 itself is shown in FIG. 2.

The applicator member 5 is in particular a block of porous material with open pores, for example a block of foam.

In particular, the applicator member 5 is especially made of polyurethane foam of type S90 (standard DIN 4102-9). Such materials are deformable and particularly compressible.

More specifically, the applicator member 5 has a head 51 defining an application surface 50 intended to contact the user's body surface, and the applicator member 5 is placed on the gripping member 41. It is extended by a bottom portion 52 intended for mounting. The coating surface 50 is planted.

In the illustrated embodiment, the mounting bottom 52 has a length of about 11 mm. The diameter is about 11 mm or slightly larger (11.3 mm in this case).

The applicator member 5 has an overall axisymmetric shape around the central longitudinal axis. The head 51 has an overall conical shape. The bottom portion 52 has a substantially cylindrical cross section.

Since the head 51 has a base portion having a cross section slightly larger than that of the bottom portion 52, a shoulder portion intended to allow the applicator member to rest on the fixing and fastening system, as described below. 57). This shoulder 57 makes it possible, in particular, to provide better fixation to the applicator member.

It is also noted that the applicator member 5 has a central incision 59 intended for insertion of the spike 44 of the fastening and fastening system, as described below, along the bottom 52. do.

The mounting bottom 52 also has an outer peripheral slot 58. The slot 58 of the mounting bottom 52 of the applicator member 5 is located approximately in the middle of the mounting bottom 52. The slot has a thickness of about 1 mm.

In the following, mounting of the applicator member 5 on the gripping portion will be described.

The gripping member 41 comprises, along with the end wall 43, a peripheral skirt 42 defining a housing for receiving the mounting bottom 52 of the applicator member 5, the applicator member 5 ).

The housing for receiving the mounting bottom 52 has a shape complementary to the mounting bottom 52, specifically in this case a cylindrical shape.

The housing for receiving the mounting bottom 52 has an internal cross section that is substantially the same as the cross section of the mounting bottom 52. In this case, the inner diameter of the cylindrical skirt 42 is substantially the same as the outer diameter of the mounting bottom 52. Thus, in the absence of additional stress, the mounting bottom 52 is not compressed radially and can simply be inserted into the housing.

The end wall 43 of the fastening and fastening system has at least one central spike 44 extending substantially perpendicular to the end wall 43. The central spike 44 is intended to engage the incision 59 of the applicator member 5.

Spikes 44 extend along a length sufficient to protrude from skirt 42.

Note that the spike 44 has a substantially constant cross section along its length. However, the spike 44 has a slightly frustoconical free end to facilitate introduction of the applicator member 5 into the incision 59.

The end wall 43 has a set of teeth 45 arranged on the periphery far from the central spike 44.

According to the present application, the fastening and fastening system also includes a clamping ring 70, which itself is shown in FIGS. 3 and 4.

The clamping ring 70 has a substantially cylindrical shape. The ring 70 is intended to be introduced inside the skirt 42, and for this purpose has an outer diameter substantially the same as the inner diameter of the skirt 42.

The clamping ring 70 is intended to be secured to the inside of the skirt 42 by clip-fastening. To this end, the clamping ring 70 has, on the outer periphery, a clip-fastening groove 71 intended to engage the inner periphery rib 46 of the skirt 42. Of course, the opposite configuration is also possible.

As indicated above, the compression of the applicator member 5 essentially depends on the thickness of the wall of the clamping ring 70, ie the difference between the inner and outer sections.

The difference between the inner cross section of the clamping ring 70 and the outer cross section of the clamping ring 70 is at least 20%, preferably at least 30%. According to the illustrated embodiment, it is between about 32% and 35%.

The clamping ring 70 has an end intended to be oriented towards the end wall 43 of the fastening and fastening system, which end engages the complementary slot 58 of the mounting bottom 52 of the applicator member. The inner radial shoulder 72 may be provided at least partially as far as possible.

The shoulder 72 has a surface intended to be oriented towards the outside of the clamping ring 70, more specifically towards the end wall 43 of the fastening and fastening system. This surface of the shoulder 72 is provided with a set of engaging teeth 75, similar to the teeth 45 on the end wall 43, which can enter the corresponding surface of the peripheral slot of the applicator member 5 do.

Like the teeth 45, the teeth 75 are arranged on the periphery of the shoulder 72. The teeth 75 are arranged to be positioned opposite the teeth 45 on the end wall 43 when the clamping ring 70 is fitted.

On the opposite side of the shoulder 72, the clamping ring 70 has an open second end. In this case, this end of the clamping ring 70 is intended to contact the shoulder 57 under the application head 51 of the applicator member 5.

The applicator member 5 is fitted on the gripping member in the manner described below.

First, the applicator member 5 is connected to the clamping ring 70.

To this end, the mounting bottom 52 of the applicator member 5 is compressed and introduced through a clamping ring 70 via an open end opposite the shoulder 72.

The mounting bottom 52 is drawn through the clamping ring 70 until the shoulder 72 enters the corresponding slot 58 of the applicator member 5.

Thereafter, teeth 75 on the shoulder enter the inner surface of the slot 58.

Thus, the clamping ring 70 extends between the shoulder 57 and the slot 58 of the applicator member and compresses the corresponding portion of the mounting bottom 52.

The base of the mounting bottom 52, which is located between the free end of the mounting bottom 52 and the slot 58, protrudes from the clamping ring, whereby it is not compressed.

Next, the applicator member 5 and the clamping ring 70 assembly are simply inserted into the housing of the gripping portion 43 defined by the skirt 42 and the end wall 43.

More specifically, the applicator member is inserted until the base end of the mounting bottom 52 contacts the end wall 43. Thereafter, the teeth 45 enter the base surface of the mounting bottom 52.

The clamping ring 70 is, for this, inserted into the skirt 42 until it is clip-fastened.

During insertion, the central spike 44 enters the corresponding incision 59 of the applicator member and contributes to the fixation of the assembly.

Thus, while the clamping ring 70 is fitted on the applicator member 5, the applicator member has a compressed intermediate portion and an uncompressed or less compressed base portion, which in the longitudinal direction is applied to the applicator member 5 ) To help maintain.

While the assembly formed by the applicator member 5 and the clamping ring 70 is fitted, the insertion of the central spike 44 into the incision 59 also increases the compression of the applicator member in the clamping ring.

The central spike 44 also contributes to the good fixation of the assembly, in particular the limitation of movement movement.

The base portion of the applicator member 5 is fixed between the spikes 45 on the end wall 43 and the spikes 75 carried by the shoulder 72 of the clamping ring 70, and the applicator member ( 5) Prevent rotation.

Therefore, the fixing of the applicator member 5 on the gripping member 4 is optimal, while being relatively simple in terms of assembly.

According to the second embodiment (not shown), the gripping member is connected to the reservoir in a non-removable manner, and the applicator member is disposed in the fluid reservoir in communication with the interior space of the reservoir containing cosmetics. Such packaging and dispensing assemblies are particularly indicated in the documents cited above. Cosmetics can advantageously be supplied through hollow central spikes 44 forming a dispensing cannula.
