Description

TECHNICAL FIELD

[0001] The present invention relates to the field of refillable applicators for cosmetics, such as refillable lipsticks or deodorants. BACKGROUND

[0002] Generally, a refillable applicator comprises a cartridge configured to collect a cosmetic product. This cartridge is generally arranged in a housing and can be manually ejected by the user so that it can be replaced by another cartridge. The ejection of such a cartridge is for example carried out by the user by applying an axial translational force to the cartridge, upwards or downwards relative to the housing. As a variant, the ejection of such a cartridge can be carried out by applying an axial rotational and translational force to the cartridge, upwards or downwards relative to the housing.

[0003] The drawback of this type of system is that it can be difficult to eject the cartridge. Furthermore, the user has to directly manipulate the cartridge in order to eject it, thus possibly coming into contact with the cosmetic product, for example possibly soiling it. SUMMARY

[0004] The aim of the present invention is to remedy the aforementioned drawbacks by proposing, as an alternative, a refillable applicator for a cosmetic product, configured to comprise a cartridge movable between an initial position and an ejected position, said applicator comprising:

[0005] - a containment housing for the cartridge, and

[0006] - a push button configured to eject the cartridge, the push button being movable between a rest position, in which the push button is configured to allow the cartridge to be in the initial position in the housing, and an ejection position, in which the push button is configured to eject the cartridge from the housing.

[0007] By cosmetic product is meant any product, more particularly a solid product, intended to come into contact with a part of the human body in order to clean said part, perfume said part, modify the appearance of said part, protect said part, keep said part in good condition or correct body odor.

[0008] In the initial position, the cartridge is configured to be arranged in the housing, whereas in the ejected position, the cartridge is configured to be at least partially arranged outside the housing.

[0009] Thus, the refillable applicator according to the invention makes it possible to simply eject the cartridge in order to replace it by limiting contact with the cartridge and thus with the cosmetic product.

[0010] The cartridge is configured to comprise a cosmetic product. This cartridge can also be called a replacement.

[0011] According to other features of the application, the applicator according to the application comprises one or several of the following optional features, taken individually or in all possible combinations.

[0012] According to one feature, the applicator comprises sealing means between the push button and the housing, when the push button is in the rest position and / or when the push button is in the ejection position. Thus, the push button cooperates with the housing in a sealed manner to allow the ejection of the cartridge.

[0013] In this way, the sealing of the applicator is guaranteed. Indeed, it is preferable to seal the applicator so that no liquid or gas can modify the cosmetic product disposed in the cartridge.

[0014] According to one feature, the push button comprises sealing means between the push button and the housing.

[0015] According to one feature, the sealing means between the push button and the housing comprise at least one tab, and preferably a plurality of tabs, disposed on the push button and clampedly bearing against the housing.

[0016] According to one feature, the sealing means between the push button and the housing comprise an overmolded part on the push button, for example made of elastomeric thermoplastic, clampedly bearing against the housing.

[0017] According to one feature, the overmolded part comprises at least one tab, and preferably a plurality of tabs.

[0018] According to one feature, the applicator has a longitudinal central axis and the housing comprises an axial tab directed toward said longitudinal central axis, configured to cooperate with the sealing means between the push button and the housing.

[0019] According to one feature, the housing comprises sealing means between the push button and the housing.

[0020] According to one feature, the applicator has a longitudinal central axis and the housing comprises an axial tab directed toward said longitudinal central axis, the axial tab comprising sealing means between the push button and the housing.

[0021] According to one feature, the sealing means between the push button and the housing comprise at least one tab, and preferably a plurality of tabs, disposed on the housing and clampedly bearing against the push button.

[0022] According to one feature, the sealing means between the push button and the housing comprise an overmolded part on the housing, for example made of elastomeric thermoplastic, comprising at least one tab, and preferably a plurality of tabs, clampedly bearing against the push button.

[0023] According to one feature, the sealing means between the push button and the housing comprises an O-ring arranged between the housing and the push button.

[0024] According to one feature, the applicator comprises a cartridge movable between an initial position, in which the cartridge is fastened to the housing, and an ejected position, in which the cartridge is detached from the housing.

[0025] Thus, the push button is configured to detach the cartridge from the housing when the push button is in the ejection position, to allow the cartridge to be ejected from the housing.

[0026] According to one feature, the cartridge comprises clamping means able to fasten the cartridge to the housing.

[0027] According to this feature, the push button is configured to unfasten the cartridge from the housing when the push button is in the ejection position.

[0028] According to one feature, the axial tab of the housing comprises a cavity and the clamping means of the cartridge comprise a protrusion configured to cooperate with the cavity of the axial tab of the housing, so as to retain the cartridge in the housing.

[0029] According to one feature, the housing is made of a plastic material. Thus, the housing has a certain flexibility.

[0030] According to one feature, the cartridge comprises:

[0031] - a ring having a recess configured to contain a cosmetic product,

[0032] - a cup able to translate axially in the recess so as to bring the cosmetic product out of the recess or into the recess, the cup having a stem with a pitch, and

[0033] - an insert comprising clamping means, the insert having a pitch complementary to the pitch of the stem of the cup,

[0034] said ring being able to move in rotation relative to the housing and cooperating with said cup so as to drive said cup to translate axially.

[0035] More particularly, the ring is configured to drive the cup in rotation and the cup cooperates with the insert due to the complementary pitches so as to be driven to translate axially. BRIEF DESCRIPTION OF DRAWINGS
