A removable cartridge sealing plug constitutes an additional sealing means to prevent the second bulk from leaking outside the cartridge reservoir or air from entering the cartridge reservoir when the cartridge is in the disassembled configuration, for example. do. The cartridge can therefore be stored without fear that the second bulk may deteriorate. Additionally, when the cartridge is used, the removable cartridge sealing plug allows the cartridge reservoir to be resealed, thereby preventing residual cosmetic product from spilling outside of the cartridge.

This device may have the following features:
The bottle has a lower threaded neck at its lower bottle end, the cartridge has a threaded outer tubular sleeve extending toward the bottle along the cartridge axis, and the lower threaded neck and threaded outer tubular sleeve connect the cartridge to the bottle. Designed to be screwed together during installation on top.

The seal opening mechanism includes a cutting edge designed to open the seal when the cartridge is placed in the mounting configuration;
The seal is configured by moving the cartridge between an exploded configuration and an installed configuration between a first sealed position in which the seal seals the cartridge reservoir and a second unsealed position in which the bottle reservoir and the cartridge reservoir are in fluid communication. can be moved relative to the cutting edge,
the seal opening mechanism is supported by the cartridge;
The lower end of the bottle comprises a lower support designed to cooperate with the seal during installation of the cartridge onto the bottle, thereby pushing the seal towards its open position.

A seal opening mechanism supported by the cartridge allows the user to manipulate the lightweight bottle. When the cartridge is installed on the bottle, the seal is opened. Therefore, the seal is easily opened due to the simple operation of the device.

In another variation, the dispensing device comprises an extension extending substantially along the bottle axis within the bottle reservoir, and the seal-opening mechanism comprises a lower pressing end of the extension, the lower pressing end causing the cartridge to open into the bottle. Designed to open the seal during installation.

The fact that the seal opening mechanism is part of the bottle's dispensing device makes it possible to implement lightweight devices in which the bottle and cartridge have a simple structure, without specific seal opening means, such as, for example, specific cutting edges. become.

In another variant, the dispensing device is a pipette.

The use of device 10 to prepare and dispense cosmetic products will now be described.

Referring to FIG. 1, a device 10 as described above is shown. The cartridge is in its disassembled configuration. The removable bottle sealing plug 22 is in its covering configuration. Removable cartridge sealing plug 62 is in its covering configuration. The dispensing device 16 is in its retractable configuration. Seal 76 is in its closed configuration. Piston 116 is located in its lower position.

The removable cartridge sealing plug 62 is removed from the structure 60 of the cartridge 14 to provide the uncovered configuration of the removable cartridge sealing plug 62.

The removable bottle sealing plug 22 is removed from the tubular wall 20 of the bottle, leaving the removable cartridge sealing plug 62 in the uncovered configuration.

The cartridge 14 is then screwed onto the lower threaded neck 32 of the bottle 12 into the cartridge 14 mounting configuration.

During installation of the cartridge 14 onto the bottle 12, the lower support 44 of the bottom end 24 of the bottle pushes the annular abutment collar 100 downward. This causes the seal 76 to move along the cartridge axis C, causing the seal 76 to break, particularly at the sealing round 96. Cylindrical skirt 98 of seal 76 moves downwardly along inner tubular sleeve 70 and along bottle axis B and cartridge axis C.

Press button 118 to place it in its upper position.

Mixing the first bulk and the second bulk. The first bulk and the second bulk form a cosmetic product.

Handling portion 130 is operated to draw cosmetic product from within bottle reservoir 28 into the conduit of extension portion 132 .

The dispensing device 16 is then removed from the bottle 12 and the dispensing device 16 is placed in its dispensing configuration.

The handling portion 130 is operated to dispense the cosmetic product from within the conduit of the extension portion 132, for example onto the user's body surface.

In the present invention, the first bulk and the second bulk are adjusted safely and optimally. This device allows the user to prepare customized cosmetic products as desired using a bulk that is protected from deterioration. In particular, the present invention prevents air from entering the cartridge reservoir, thereby protecting the active ingredient within the cartridge reservoir.

The device is easy to use since all the steps required are based on screwing and unscrewing movements, for example.

According to a second embodiment of the invention, shown in FIG. 4, a seal 76 is removably attached to the inner tubular sleeve 70. Seal 76 is not fragile.

The peripheral annular recess 124 of the button 118 is designed to cooperate with the inner surface of the inner tubular sleeve 70 when the button 118 is pressed by the user. The inner surface of the inner tubular sleeve 70 thus guides the button 118 when it is pressed by the user.

Seal opening mechanism 18 includes a lower pressing end 186 of extension 132 of dispensing device 16 . Lower pressing end 186 is designed to open seal 76 during installation of cartridge 14 onto bottle 12. A lower pressing end 186 is defined on the lower extension end 156 of the extension 132 of the dispensing device 16 . A lower pressing end 186 is defined, for example, on the tip of a pipette.

In particular, the lower pushing end is designed to push the seal 76 downwardly, thereby causing the annular sealing projection 182 to disengage from the annular sealing recess 180, while installing the cartridge 14 onto the bottle 12. In that case, the seal 76 is free to move relative to the inner tubular sleeve 70 and is placed in the unsealed position of the seal 76. Bottle reservoir 28 and cartridge reservoir 102 are then in fluid communication.

According to a second embodiment of the invention, a circular attachment projection 40 extends radially from the bottle top 26 towards the bottle axis B.

According to a variant, the second bulk is a liquid.

According to a variant of the first and second embodiments of the invention, the cartridge does not include a piston. In that case, cartridge reservoir 102 is defined by inner tubular sleeve 70, seal 76, and a fixed lower wall.
