Technical Field

The present invention relates to a system for mixing two cosmetic products.

More particularly, the invention relates to a system that allows mixing together two products, for example a dye or an active of the vitamin C or a vitamin a type, with a foundation base.

At least one of the two initial products must be protected from any air pollutants, to prevent their degradation.

Background

Known is the type of system for mixing two cosmetic products, comprising a tubular bottle defining a first reservoir (which contains the first product to be mixed) and a tubular cartridge defining a second reservoir (which contains the second product to be mixed).

The first reservoir and the second reservoir are separated by a cap.

The cartridge has a pump that, when activated, perforates the cap and injects the second product into the first reservoir to mix the two products.

Systems of the above type do not appear to allow the selection of a combination of two products to be mixed.

Disclosure of Invention

The present invention aims in particular to overcome these drawbacks and for this purpose relates to a system for mixing two cosmetic products, comprising:

a tubular bottle defining a first reservoir adapted to contain a first product to be mixed, said bottle extending axially along a main axis from an upper end forming a dispensing mouth to a lower end,

a base sealing the lower end of the bottle and comprising an access port communicating with the first reservoir, the access port being sealed by a cap,

-a tubular cartridge defining a second reservoir adapted to contain a second product to be mixed, said cartridge extending axially along a main axis from an upper end to a lower end forming an injection port for injecting said second product,

characterized in that the system comprises:

-retaining means adapted to retain the cartridge on the bottle in an injection position in which the first reservoir communicates with the second reservoir via the entry port of the base and the injection port of the cartridge,

-a perforator having an upper edge adapted to perforate the cap, the cap sealing the access opening of the base when the cartridge is in its injection position,

-an injection means sealing the lower end of the cartridge and being movably mounted axially between a low initial position and a high final position to push the second product from the second reservoir through the injection port of the cartridge to the first reservoir.

The system according to the invention allows the user to obtain numerous combinations of mixed products, depending on the cartridge chosen.

In addition, the system according to the invention allows mixing products of different nature.

Indeed, the second product contained by the cartridge may be, for example, a liquid, a powder or granules.

In one embodiment, the perforator axially spans the cartridge injection port.

Thus, two different elements allow to perforate the cap and to push the second product into the bottle. Thus, the forces are decoupled and improve the performance of the system.

The injection device is a piston.

According to this characteristic, the piston is axially slidably mounted between a lower initial position and an upper final position to push the second product from the second reservoir to the first reservoir through the injection port of the cartridge.

Optionally, the injection device is a flexible septum.

In an advantageous manner, the base has a substantially cylindrical shape along a main axis from an upper end to a lower end and is tightly and sealingly mounted on the lower end of the bottle.

According to one characteristic, the base is inside the bottle.

The cap is preferably arranged at the upper end of the base such that it is not easily accessible to a user and it is not unintentionally perforated. These characteristics allow to improve the security of the system.

According to another feature, the retaining means comprises a thread extending around the spindle and formed on the outer face of the barrel, and a complementary tapping formed on the inner face of the base.

According to another characteristic, the lower end of the barrel is equipped with a driving ring, which is fixed to move with respect to the barrel and which is arranged to allow the user to screw the barrel on the bottle base.

According to another characteristic, the ring is a breakable ring connected to the body of the cartridge by a plurality of radial retention projections, which are mechanically weakened so that, after screwing the cartridge, the user can apply a torque to the ring which breaks the retention projections and disengages the ring from the cartridge.

This feature allows the injection device to be released for user access.

According to another characteristic, the perforator has the shape of a bevelled cylindrical segment extending around the main shaft and arranged on the upper end of the barrel to perforate a cap sealing the base access opening.

According to another feature, the cartridge includes a check valve connected to the cartridge injection port to prevent inadvertent flow of the second product contained in the cartridge.

According to another characteristic, the system comprises a movable stopper adapted to ensure the sealing of the cartridge.

According to another characteristic, the dispensing mouth of the bottle is equipped with dispensing means suitable for dispensing the mixture of the first product and the second product contained in the first reservoir.

The aforementioned bottle and cartridge may be used independently of each other.

The invention relates more particularly to a tubular bottle defining a first reservoir suitable for containing a first product to be mixed, intended to receive a tubular cartridge defining a second reservoir suitable for containing a second product to be mixed, said bottle extending axially along a main axis from an upper end forming a dispensing mouth to a lower end, characterized in that the bottle comprises an inner base sealing the lower end of the bottle and an access opening communicating with said first reservoir, said access opening being sealed by a cap, and the base being suitable for cooperating with said cartridge.

All the features relating to the bottle in the system for mixing two cosmetic products may be considered to be independent of the cartridge, although these features are not claimed.

The invention also relates to a tubular cartridge for cooperating with a tubular bottle defining a first reservoir suitable for containing a first product to be mixed and comprising a base sealed by a cap, said cartridge defining a second reservoir suitable for containing a second product to be mixed and extending axially along a main axis from an upper end to a lower end forming an injection port for said second product, characterized in that it comprises:

-a perforator having an upper edge adapted to perforate the cap of the bottle when the cartridge is in its injection position, the perforator being axially across the cartridge injection port,

-an injection means sealing the lower end of the cartridge and being movably axially mounted between a lower initial position and an upper final position for pushing the second product from the second reservoir through the cartridge injection port to the first reservoir.

All of the features described in relation to the cartridge in the system for mixing two cosmetic products may be considered to be independent of the bottle, although these features are not claimed.

Detailed Description

Fig. 1 shows a system 10 for mixing a first cosmetic product 12, such as an active, with a second cosmetic product 13, such as a foundation.

The system 10 includes a vial 14 defining a first reservoir 16 adapted to contain a first product 12 to be mixed.

The bottle 14 extends axially along a vertical major axis a from an upper end 18 (which forms a dispensing opening 20) to a lower end 22.

The dispensing port 20 of the bottle 14 forms a threaded port on which a pump dispenser 24 is threadably attached.

It will be appreciated that the type of dispenser, which may be, for example, a pump type or a sprayer type, may vary depending on the product mix contained in the first reservoir 16.

The lower end of the bottle 14 is sealed by a base 26, which has a generally cylindrical shape along a major axis a from an upper end 260 to a lower end 261, and which fits tightly and sealingly over the lower end of the bottle 14.

The base 26 is inside the bottle 14.

The circumferential dimensions of the base 26 are complementary to those of the first reservoir 16 so that it lies tightly and sealingly within the bottle 14, against the first reservoir 16.

The base 26 and bottle 14 are monolithic. They form a single block.

The base 26 contains an access port 28 which communicates with the reservoir 16 of the bottle 14 and is sealed by a cap 30 disposed at its upper end 260.

The base 26 is open at its lower end 260.

The inlet port 28 of the base 26 forms a cylindrical conduit adapted to mate with the barrel 32.

The cartridge 32 has a tubular shape defining a second reservoir 34 adapted to contain the second product 13 to be mixed.

The barrel 32 extends axially along the major axis a from an upper end 36 (which forms an injection port 38 for the second product 13) to a lower end 40.

The injection port 38 of the cartridge 32 forms a cylindrical conduit adapted to fit into the conduit formed through the inlet port 28 of the base 26.

Also, the injection port 38 is sealed by a check valve 42 adapted to retain the second product 13 within the cartridge 32. The check valve 42 is, for example, a flexible diaphragm, chamfered at its center, visible in fig. 5.

Likewise, the injection port 38 is axially spanned and extended by a perforator 44, the perforator 44 having a beveled upper edge 46 designed to perforate the cap 30 (which seals the base 26 into the port 28).

The cylinder 32 is equipped with a piston 48 which seals the lower end 40 of said cylinder 32 and which has a cylindrical shape along the main axis a.

The piston 48 is axially delimited by an upper face 50, which forms a projection 52 adapted to come into contact with the check valve 42, and by a lower face, which forms a bottom 54 of the cylinder 32.

The piston 48 is axially slidably mounted along the main axis a between a lower initial position (shown in fig. 1 and 2 in which the bottom 54 of the piston 48 is flush with the lower end of the cylinder 32) and an upper final position (shown in fig. 3 in which the projection 52 of the piston 48 supports or nearly supports the check valve 42).

To slidably drive the piston 48 to push the second product 13 through the injection port 38 of the cartridge 32, the user must push the bottom 54 of the cartridge 32 axially upward.

The circumferential dimensions of the piston 48 are complementary to those of said second reservoir 34, so that it can slide in said reservoir 34 while contacting the inner wall of said second reservoir 34 and it can drive the entire second product 13 into the first reservoir 16.

Thus, when the cartridge 32 is installed in the conduit, the perforator 44 is axially displaceable along the axis a in the conduit formed by the base 26 into the port 28, and when the user pushes the piston 48 axially upwards, the piston 48 is axially slidable along the axis a in the cartridge 32.

Two different elements allow to perforate the cap 30 and push the second product 13 into the bottle 14. According to another aspect, the system 10 comprises a retaining device 56 adapted to retain the cartridge 32 in an injection position on the bottle 14, as shown in fig. 2 and 3, in which the cartridge 32 is arranged to inject the second product 13 into the first reservoir 12 via the base 26 access port 28 and the cartridge 32 injection port 38.

To this end, the retaining means 56 comprise a thread 58 extending around the main axis a and formed on the outer face of the barrel 32, and a complementary tapping 60 formed on an inner face 62 of the base 26.

To tighten the barrel 32 onto the base 26 of the bottle 14, the lower end 40 of the barrel 32 is equipped with a drive ring 64 that is fixed for movement relative to the barrel 32.

The ring 64 has a diameter greater than the diameter of the upper portion of the barrel 32 and is substantially equal to the diameter of the bottle 14 so that the ring 64 and bottle 14 form a uniform cylinder, as can be seen in fig. 2.

Without limitation, the retaining device 56 may also be produced by releasable interlocking, by a form fit between the cartridge 32 and the base 26 of the bottle 14.

As can be seen in fig. 4, the system 10 comprises a movable plug 66 adapted to ensure the sealing of the cartridge 32.

The plug 66 has a generally cylindrical skirt that includes a threaded inner wall 68 that allows the plug 66 to be screwed and unscrewed on the cartridge 32 to protect the product 13 contained in the cartridge 32.

In addition, the skirt of the plug 66 ensures sealing of the cartridge 32.

An example of the operation of the system 10 according to the invention is described below.

The user selects the cartridge 32 according to the product mix he wishes to obtain, unscrews the stopper 66 and then screws the cartridge 32 onto the bottle 14 by means of the ring 64 provided on this end, as shown in figure 2.

During tightening of the cartridge 32, the beveled upper edge 46 of the perforator 44 perforates the cap 30 (which seals the access opening 28 of the base 26 of the bottle 14).

The barrel 32 is in its injection position as the barrel 32 is screwed on until the end of the stroke, which is the position in which the user pushes the piston 48 from its lower initial position to its upper final position.

During the sliding of the piston 48, the second product 13 is injected from the cartridge 32 into the reservoir 16 of the bottle 14 through the port provided to this end, so that said first product 12 is mixed with the second product 13 in the reservoir 16 of the bottle 14.

After this mixing, the user activates the pump dispenser 24, which dispenses the mixture of product contained in the reservoir 16 of the bottle 14.

Fig. 5 shows a variant embodiment of the system 10 according to the invention, comprising a rupturable drive ring 64.

To this end, the ring 64 is connected to the body of the barrel 32 by a plurality of radial retaining projections 70, the retaining projections 70 being mechanically weakened so that, after screwing the barrel 32, the user can apply a torque to the ring 64 which breaks the retaining projections 70.

Once the ring 64 is disengaged from the barrel 32, the piston 48 is exposed to encourage the user to lower it.

Also, fig. 6 shows another variant embodiment of the system 10 according to the invention, comprising a sliding perforator 72.

The perforator 72 forms a cylindrical ring which extends around the main axis a and which allows the passage of the second product 13.

The perforator 72 has a beveled upper edge 76 provided to perforate the sealing cap 30 of the base 26 into the port 28, a lower section 78 provided to penetrate into the injection port 38 of the cartridge 32, and an intermediate annular flange 80 extending around the perforator 72.

In addition, the perforator 72 comprises a claw 82 extending from an inner neck 83 arranged inside the perforator 72 and adapted to perforate a cap 84 (which seals the injection port 38 of the cartridge 32).

The access port 28 of the base 26 forms a cylindrical cage in which the perforator 72 is axially slidably mounted between an upper seat 86 and a lower seat 88 formed by the access port 28 of the base 26.

Thus, when the cartridge 32 is screwed onto the base 26, the injection port 38 of the cartridge 32 penetrates the perforator 72, the claw 82 pierces the cap 84 (which seals the injection port 38 of the cartridge 32), the injection port 38 of the cartridge 32 bears against the neck 83 to push the perforator 72 upwards, and the bevel upper edge 76 then perforates the sealing cap 30 of the base 26 into the port 28.
