Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refill product for a hair treatment device having a coupling relief,

The present invention relates to devices for treating hair, and more particularly but not exclusively, to devices for shaping hair, in particular for straightening, curling or crimping hair, including refill products of cosmetics .

The present invention relates in more detail to devices comprising two jaws, the jaws being movable relative to each other and having a spaced-apart configuration for introducing a tuft of hair between the jaws, The jaws may be moved-together to process the hair of the tufts, and the jaws are movable along the tufts' hair in a configuration that moves together. In such devices, the jaws often bear the two heating elements that the hair contacts during use of the device.

Numerous devices of this type, also known as straightening irons, have already been proposed.

Typically, hair straighteners are made up of two arms, which are connected together with the aid of a hinge and at least one heating element arranged on the arms, which enable to open and close the arms. During the act of styling a tuft of hair, the hair of the tuft is introduced between the two arms in the open position, and then the two arms are manually closed over the hair of the tuft. The hair is then subjected to heat output by a heating element until the two arms are opened and the hair of the tuft is removed.

The application WO 2009/078046 describes a hair styling appliance which comprises two arms connected together to open and close the appliance, at least one heating element and at least one sheet for receiving the hair treatment device Wherein the hair treatment device allows the hair care product to be dispensed during operation. The hair treatment device is comprised of a support material that is impregnated and disposable for the hair care product.

WO 2009/015027 and US 2009/0025247 disclose a hair straightening device that allows the hair care product to be applied by contact with the hair. The hair care product to be applied is contained in a removable refill product for its application. The removable refill product comprises a reservoir containing a hair care product in the form of a gel and orifices for dispensing and applying the product, the orifices being made to penetrate directly through the walls of the reservoir. The refill product is introduced by sliding into a housing disposed in one of the two arms of the hair straightener.

Application WO 2013/045331 discloses an applicator for applying a care material to a hair, the applicator comprising a cartridge of care material held in a housing of the applicator. The cartridge includes a porous support saturated with a care substance.

The application WO 2013/090896 relates to an appliance for treating hair, in particular a hair styling appliance, which comprises a treating agent support, in particular a saturated porous material, to be applied to the hair or skin. The backing is secured to an accessory that is itself attached to the hair treatment appliance in a removable manner. The support is T-shaped and the support can be mounted in the complementary groove of the accessory.

There is a need to further improve the devices for applying the hair care product so that the user can easily refill the hair care product in the device and / or change the hair care product to be applied.

According to a first aspect of the present invention, the subject matter of the present invention is a refill product for a device for treating hair,

A body at least partly formed by two opposed walls and a bottom and having a cavity opening outwardly by an opening,

And an applicator member inserted into the cavity of the body along the insertion axis X and extending out of the cavity through the opening.

Wherein at least one of the bottom and the walls of the cavity includes at least one coupling relief wherein the coupling relief engages the applicator member to prevent the applicator member from being extracted from the cavity, The relief is designed such that the force for inserting the applicator member into the cavity is less than the incremental output.

The applicator member can be easily inserted into the cavity and it can be more difficult to extract. This enables the applicator member to be properly retained therein.

The applicator member is then inserted and extracted in opposite directions along the same path.

The coupling relief may be designed to damage the applicator member during extraction of the applicator member. Thus, the applicator member can not be reused and therefore can limit health risks associated with reuse.

The coupling relief may be designed to separate from the wall or the floor supporting the wall, particularly by breakage, while extracting the applicator member from the cavity such that the refill product can not be reused.

The difference [ Delta] F between the force for inserting the applicator member into the cavity and the force for extracting the applicator member from the cavity may be 3N or more, preferably 4N or more.

Preferably, the applicator member is made of synthetic or natural fibers that are all oriented and assembled in substantially the same direction to form a porous material, particularly a felt. The applicator member may have a fiber density of 0.080 g / cm ³ to 0.400 g / cm ^3. Such materials make it possible, in particular, to package and apply cosmetics.

In an alternative embodiment, the applicator member includes at least two portions having different fiber densities and / or fiber orientations. For example, one of the two portions may form a product reservoir, and the other may allow application of a cosmetic article.

Preferably, the applicator member is impregnated with a cosmetic article.

Preferably, the applicator member is compressible. While inserting the applicator member into the cavity, the applicator member can be deformed locally in contact with the coupling relief, and can mold itself to some extent in the shape of the cavity. During extraction of the applicator member from the cavity, the coupling relief may retain the applicator member inside the cavity, particularly by engaging the fibers of the applicator member, particularly the applicator member.

The applicator member may include pre-cut regions intended to be torn during extraction of the applicator member from the cavity, rendering the applicator member non-reusable.

Preferably, the coupling relief extends from the wall or the bottom in a direction substantially perpendicular to the direction of the fibers of the applicator member. In this configuration, the coupling relief can tear the fibers by engaging the fibers of the applicator member with the fibers of the applicator member, thereby damaging the applicator member and preventing reuse of the applicator member.

Preferably the cavity has a defined height H along the insertion axis X from the opening and the coupling relief extends along the insertion axis X along the length l less than this height H .

Preferably, the coupling relief is asymmetric with respect to the central transverse plane of the coupling relief. This asymmetry makes it possible to have especially the insertion properties of the applicator member different from the extraction properties of the applicator member.

Preferably, the coupling relief has a thickness e measured in a plane which is variable along the insertion axis X or in a plane perpendicular to said bottom. Preferably, the thickness (e)

- increase along the entire length (l) of the coupling relief along the insertion axis X of the applicator member, or

Is increased along the first part of the length l ₁ along the insertion axis X and then constant along the second part of the length l ₃ along the insertion axis X, Is less than the maximum thickness (e _max ) of the first portion.

This makes it possible to have a coupling relief with a shallower slope in the insertion direction of the applicator member than the slope in the extraction direction. This may make it particularly difficult to extract the applicator member.

When the coupling relief is in one of the opposing walls, the opposing walls can not have a coupling relief from the bottom of the cavity to a non-zero height h. As a result, once the applicator member is introduced into the cavity, the applicator member at least partially extends below the coupling relief in the cavity. This allows the coupling relief to better engage the fibers of the applicator member, especially the applicator member, in the extraction direction.

Preferably, the or each coupling relief comprises:

- a first face oriented towards the opening and having an average slope which forms an angle (?) Of 45 ° or less with the insertion axis (X)

The first and second surfaces may form an angle? At no more than 110 degrees, more preferably no more than 90 degrees and / or more than 45 degrees at their contacts.

The coupling relief may have at least one ridge, in particular a longitudinal ridge and / or a transverse ridge, at the point of contact between the first and second surfaces.

The coupling relief may have a substantially triangular or arrowed profile in its longitudinal section, especially when the coupling relief is in one of the opposed walls, and the leading edge is in the form of an opening, Lt; / RTI >

When the coupling relief is at the bottom, the coupling relief may have a shape that is circular, in particular polygonal or not, in cross-section.

The maximum thickness (e _max ) of the coupling relief measured in a plane perpendicular to the wall or to the wall to which the coupling relief is attached may be 0.2 mm to 3 mm, more preferably 0.5 mm to 2 mm.

The coupling relief may extend along the insertion axis X along a length (l) of 1 mm to 30 mm, more preferably 5 mm to 15 mm.

The coupling relief may have a maximum width k measured parallel to the wall of 0.2 mm to 5 mm, more preferably 0.5 mm to 2 mm.

Preferably, the coupling relief is molded with the body.

In a variant, the coupling relief is fitted in the cavity. The coupling relief may be made of a material different from the body.

The coupling relief may include a narrower area, particularly a smaller width area configured to break when the user retrieves the applicator member from the cavity.

At least one or the bottom of the walls may comprise a plurality of coupling reliefs. At least one wall or bottom may include fewer than ten coupling reliefs, more preferably three to eight coupling reliefs.

All coupling reliefs may be the same. In a variation, at least one of the coupling reliefs is different from the other.

One and / or the bottom of the two opposing walls may not have a coupling relief, or the two opposing walls and / or the bottom may each have at least one coupling relief.

The coupling reliefs of one of the opposing walls may be located facing the other coupling reliefs of the opposing walls. In a variant, the coupling reliefs of one of the opposed walls alternate with the coupling reliefs of the other of the opposed walls.

Preferably, the opposed walls are planar and parallel to each other. The floor may be flat.

Preferably, the cavity has an elongated shape in a direction perpendicular to the insertion axis.

Preferably, the cavity is closed except for the opening.

Preferably, the cavity has a substantially rectangular parallelepiped shape.

Preferably, the body of the refill product has a U-shaped cross section.

Preferably, the applicator member has a shape complementary to the shape of the cavity, particularly the shape of the rectangular parallelepiped.

The cavity may be defined by a front wall, a rear wall opposite the front wall, two opposed sidewalls, and a bottom against which the applicator member can strike. At least one of the front and rear walls, sidewalls, and bottom includes a coupling relief.

The body of the refill product may comprise a thermoplastic material, in particular polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyamide (PA), elastomer, polypropylene, copolyester, especially Tritan or mixtures thereof, And PET. ≪ / RTI >
