Benefits of technology

[0025]Preferably, when the hair product in in oily form, the application member is hydrophobic. This allows better distribution of the hair product in the application member when said product is in oily form.
[0026]Preferably, when the hair product in aqueous form, the application member is hydrophilic. This allows better distribution of the hair product in the application member when said product is in aqueous form.
[0027]Preferably, the application member has a cross section greater than or equal to that of the opening. This makes it possible to achieve gripping of the application member in the opening and to avoid the hair product leaking out at the opening. This dispenses with the need for the presence of an additional seal between these two elements.
[0028]Preferably, the applicator member is integral with the reservoir. This makes it possible to guarantee better sealing of the reservoir.
[0029]In a variant, the application member is mounted in the reservoir in a removable manner. This makes it possible, when this is desirable, to easily replace a worn-out application member without having to change the reservoir.

Problems solved by technology

A refill of this type does not allow as constant an application of hair product as desired during its use.
Refills of this type are fairly complex and expensive to produce owing to the presence of the pump.
The supply of product to the application member tends to vary as a function of the orientation of the refill, which may be detrimental to the uniformity of the result.
Moreover, the fact that the application member is unable to move lowers the risk of hair product leaking out at the reservoir opening.

example 2

[0096]In this example, the refill 20 is as illustrated in FIGS. 3 and 4.

[0097]The application member is a porous material made from hydrophobic polyethylene having a mean pore size of 20 to 60 μm.

[0098]The hair product contained in the refill is the same as that in Example 1. The weight of hair product contained in the refill is approximately 7.2 g.

[0099]The refill 20 is mounted on a system identical to that of Example 1.

[0100]The hair product is applied to standard locks identical to that of Example 1 according to the same operating method as that of Example 1.

[0101]The graph according to FIG. 6 represents the amount of hair product applied in each operation as a function of the number of times the system has been used on the standard locks of hair.

[0102]The amount of hair product applied is substantially constant between the first and the 75th operations. There is no observable significant decrease, unlike in Example 1.

[0103]The amount of hair product measured is 0.064 g+ / −0.02 g ...

example 3

[0104]In this example, the refill 20 is as illustrated in FIG. 7.

[0105]The application member is identical to that of Example 2. The hair product contained in the refill is the same as that in Examples 1 and 2.

[0106]The weight of hair product contained in the refill is approximately 3.8 g.

[0107]The refill 20 is mounted on a system identical to that of Examples 1 and 2.

[0108]The hair product is applied to a standard lock identical to that of Examples 1 and 2 and the same operating method is used.

[0109]The graph according to FIG. 8 represents the amount of hair product applied in each operation as a function of the number of times the system has been used on the standard locks of hair.

[0110]The amount of hair product applied is substantially constant between the first and the 75th operations. There is no observable significant decrease, unlike in Example 1.

[0111]The amount of hair product measured is 0.0126 g+ / −0.0025 g per lock. The variation in amount of hair product deposited per l...

[0112]In this example, the refill 20 is as illustrated in FIG. 9.

[0113]The application member is a porous material made from hydrophobic polyethylene having a mean pore size of 20 to 60 μm.

[0114]The hair product contained in the refill is the same as that in Examples 1 and 2.

[0115]The weight of hair product contained in the refill is approximately 3.4 g.

[0116]The refill 20 is mounted on a system identical to that of Examples 1 and 2.

[0117]The hair product is applied to a standard lock identical to that of Examples 1 and 2 according to the same operating method.

Abstract

The present invention relates to a cosmetic refill (20) intended to be inserted in a removable manner into a housing in a system (2) for treating the hair, comprising: —a hair product reservoir comprising an opening, —a porous application member (26) extending partially into the reservoir through the opening, the application member (26) being fixed in the reservoir when the refill (20) is used.

Description

[0001]The present invention relates to a cosmetic refill for applying a hair product intended for use in a hair treatment system. The invention also relates to a hair treatment system comprising a refill of this type and to a method for treating the hair using such a system.PRIOR ART[0002]U.S. Pat. No. 8,561,620 describes a cosmetic refill comprising a porous application member soaked with product. A refill of this type does not allow as constant an application of hair product as desired during its use. The amount of product deposited on the hair in fact decreases very rapidly in step with the number of uses of the refill.[0003]International applications WO 2014 / 064660 and WO 2015 / 097625 disclose cosmetic refills allowing the application of a hair product which have a reservoir containing the product and a porous application member separate from the reservoir, the product being conveyed from the reservoir towards the application member by means of a pump. Refills of this type are fa...
