Description

Beauty refill to apply hair products

The present invention relates to a cosmetic refill for applying a hair product for use in a hair treatment system. The invention also relates to a hair treatment system comprising this type of refill and a method for treating hair using such a system.

US 8 561 620 describes a cosmetic refill comprising a porous application member into which the product is immersed. This type of refill does not consistently allow the application of the hair product as desired during its use. In fact, the amount of product deposited on the hair decreases very quickly depending on the number of refills used.

International applications WO 2014/064660 and WO 2015/097625 disclose cosmetic refills that allow the application of hair products, and the cosmetic refills include a storage unit containing the hair product and a porous application member separate from the storage unit. And the hair product is conveyed by a pump from the reservoir toward the application member. These types of refills are quite complex and expensive to manufacture due to the presence of a pump.

Likewise, patent application US 2009/0025247 discloses a hair product refill comprising a reservoir and a porous application member, the porous application member being partially immersed in the reservoir and coming into contact with the hair during use of the device. The supply of product to the application member tends to change as a function of the orientation of the refill, which may be detrimental to the uniformity of the result.

There is a need for hair product refills that are easy to manufacture and use, and that allow a relatively constant application quality of the hair product over time.

According to a first aspect of the invention, the invention responds to this need with the aid of a cosmetic refill intended to be inserted in a removable manner into the housing of a system for treating hair, the refill comprising:

-A hair product storage unit having an opening,

-Comprising a porous coating member partially extending into the storage unit through the opening,

The application member is fixed within the reservoir when the refill is used.

The fact that the application member cannot move within the reservoir allows the application member to be in a location within the same reservoir regardless of the pressure applied to the application member when the hair product is applied to the hair or the level of the hair product in the reservoir. . Thus, the amount of product delivered when treating hair is independent of the orientation of the refill, for all intents and purposes. Therefore, the application of the hair product by the application member is more easily controllable and reproducible. Moreover, the fact that the application member cannot move lowers the risk of leakage of the hair product from the opening of the reservoir.

Preferably, the refill comprises a body comprising a cavity defining a reservoir, and the hair product is preferably in liquid form.

Advantageously, the application member extends into the reservoir over the entire height of the reservoir and is advantageously placed on the bottom of the reservoir. This allows the application member to come into contact with the hair product contained in the storage unit so that the hair product is always supplied, regardless of the position of the refill.

Preferably, the application member extends only over a portion of the width of the reservoir.

Preferably, the application member extends over the entire length of the reservoir.

Preferably, the application member has at least two opposing sides, said opposing sides at least partially extending into the reservoir and at least partially contacting the hair product contained within the reservoir. The fact that the two opposite sides are in contact with the hair product allows a larger contact surface area between the hair product and the application member and allows a more uniform supply to the application member.

The application member may be made of any material capable of carrying the hair product by means of the capillary effect.

Preferably, the application member is sufficiently rigid to retain its shape when applied. This makes it possible to avoid particularly undesirable pumping effects.

Preferably, the application member is from a sintered material, in particular plastics, preferably thermoplastics, a frit, for example a polyolefin, and in particular a PE frit, for example a frit sold by Porex Corporation under the reference number XS49010. Is manufactured.

Preferably, the application member is molded. This makes possible a variety of possible forms.

Preferably, the application member has a substantially prismatic shape, in particular a parallelepiped shape, in particular a right angled parallelepiped shape. This form is easier to manufacture.

Preferably, the application member has a rounded application surface to facilitate application to the hair.

The porosity of the application member, defined by the ratio of the volume of pores to the total volume of the material, may be 0.05 to 2, and more preferably may be substantially equal to 0.4.

The application member may have a density of 0.11 to 0.25 g/cm ³ .

The average pore size may be 5 to 100 µm, more preferably 20 to 60 µm. This porosity level allows for good supply of the hair product to the application member by means of the capillary effect, while allowing good retention of the hair product in the application member. Preferably, the porosity of the application member is selected as a function of the viscosity of the hair product so that the hair product is immersed in the application member when the application member orients the head downward, but the hair product does not flow from the application member under gravity.

The thickness of the application member may be 3 cm or less. This thickness means that the hair product can easily immerse the application member up to the core between two applications. When the application member is engaged with the elongate opening, the thickness is measured perpendicular to the axis of the opening and the longitudinal axis of the application member.

Hair products may be anhydrous or aqueous compositions.

Preferably, when the hair product is in oily form, the application member is hydrophobic. This allows a better distribution of the hair product in the application member when the hair product is in oily form.

Preferably, when the hair product is in aqueous form, the application member is hydrophilic. This allows a better distribution of the hair product in the application member when the hair product is in aqueous form.

Preferably, the application member has a cross section that is greater than or equal to the cross section of the opening. This makes it possible to achieve gripping of the application member in the opening and prevent leakage of the hair product at the opening. This eliminates the need for the presence of an additional seal between these two elements.

Preferably, the application member is integral with the storage portion. This makes it possible to ensure a better sealing of the reservoir.

In a variant, the application member is mounted in the reservoir in a removable manner. This makes it possible to easily replace the old application member without the need to replace the reservoir when desired.

The application member may be simply held in the opening by friction.

Preferably, the body of the reservoir is of a substantially cylindrical shape, in particular with a polygonal, for example a rectangular base, or preferably a circular base. In the case of a cylindrical reservoir of a circular base, it is possible to have a larger amount of hair product while maintaining good contact between the hair product and the application member due to the shape of the funnel facing the application member. Thus, the distribution of hair products in the application member is improved, which optimizes the cost and environmental impact of refills.

The volume of the hair product contained in the free form in the storage unit, that is, the volume of the hair product excluding the hair product impregnated in the application member may be 100 ml or less.

The reservoir may include a hair product filling hole closed by a removable stopper.

Preferably, the storage section does not have an airreturn port. In practice, the application member is sufficiently porous to allow air to return. In a variant, the storage section has an air return port.

Another subject of the present invention is a system for treating hair, the system,

-A device for treating hair,

-A refill, according to the first aspect of the invention, mounted on the device.

Preferably, the device comprises two arms, the arms being movable relative to each other between a closed configuration for processing the hair and an unfolded configuration for engaging the hair to be treated between the arms, the One of the arms comprises a housing, the refill being arranged in a removable manner in the housing.

The arm opposite to the arm in which the refill is arranged can have a steam outlet and preferably also a comb.

Preferably, in particular when it is intended to straighten the hair, the device comprises a heating element intended to be in contact with the hair, more preferably two heating elements each arranged on each arm. This heating element or these heating elements may each comprise a plate made of a material that is a good conductor for heat, the plate defining a hot surface for contacting the hair, the temperature of which is, for example, 95 It is at least 90°C, more preferably 90°C to 230°C.

Preferably, the product is applied to the lock of hair introduced into the device prior to application of steam and/or straightening and/or combing by means of heating element(s). Thus, the hair introduced between the arms can contact the application member before being exposed to the steam and heating elements as the skein moves between the arms of the device.

Preferably, the device for treating hair according to the invention is a straightener with flat heating elements which come into contact, in particular in a closed configuration of arms.

A further subject of the invention is a method for treating hair comprising the step of applying a hair product to a hair skein using a system according to the invention, as defined above.

Preferably, the amount of hair product deposited in one application by applying a pressure of 34 N and moving the applicator at a speed of 2 cm/s on a standard 80 g/m ² paper sheet of 27 cm length is from 0.005 g to 0.5 g.

The amount of hair product deposited into the refill in one application applying a pressure of 34 N and moving the applicator at a rate of 2 cm/s on a standard 80 g/m ² paper sheet of 27 cm long It can vary by up to 50%, more preferably 35%, even more preferably 20% from the amount of product deposited between 75 applications.
