Description

The present invention relates to a device for packaging and dispensing a cosmetic product prepared by mixing a first bulk and a second bulk, comprising:
a bottle defining a bottle reservoir designed to contain a first bulk, the bottle reservoir extending along a bottle axis between a bottle upper end and a bottle lower end of the bottle;
a cartridge extending along a cartridge axis between a cartridge upper end and a cartridge lower end, the cartridge defining a cartridge reservoir designed to contain a second bulk, the cartridge including a seal for sealing the cartridge reservoir, the cartridge being arranged in a disassembled configuration in which the cartridge is spaced from the bottle and in an attached configuration in which the cartridge is attached onto the bottle;
a seal-opening mechanism adapted to open the seal when the cartridge is disposed in an installation configuration, the seal-opening mechanism being in fluid communication with the bottle reservoir and the cartridge reservoir in the installation configuration;
The present invention relates to a device of this type comprising a discharge device for discharging a first bulk or cosmetic product from a bottle reservoir, the discharge device being attached to the top end of the bottle.

Such devices are intended to be used by a user to dispense cosmetic products, for example onto the body surface.

Such devices allow a user to prepare a particular cosmetic product using a particular bulk according to his/her desires. For example, different bulks contained in different cartridges allow multiple mixes to suit the user's preferences.

The cosmetic product is, for example, a beauty product, a hair dye product or a make-up product for the body surface. The cosmetic product is in particular in the form of a liquid or gel.

More generally, a cosmetic product is a product as defined in EC Regulation No 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products.

WO2018/206898A1 discloses a device for mixing two cosmetic products, the device comprising a bottle defining a first reservoir containing the first product, a cartridge defining a second reservoir containing the second product, the cartridge being mountable onto the bottle, a seal sealing the first reservoir, and a seal-opening mechanism for piercing the seal during mounting of the cartridge onto the bottle.

It may be difficult for a user, for example, to properly position and replace a cartridge onto a bottle without spilling or degrading the bulk of either the bottle or the cartridge.

WO2018/206898A1

EC Regulation No 1223/2009

One object of the present invention is to provide a device that is easy to use and safely packages bulk, thereby allowing the formulated cosmetic product to exhibit optimal cosmetic properties.

To this end, the invention relates to a device of the aforementioned type, in which the cartridge is provided with a removable cartridge sealing plug, which is designed to cover the seal in the disassembled configuration, and which is replaced by the bottle in the installed configuration.

The 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, for example, in a disassembled configuration. The cartridge can therefore be stored without fear that the second bulk may deteriorate. Furthermore, when the cartridge has been used, the removable cartridge sealing plug makes it possible to reseal the cartridge reservoir, so that residual cosmetic product is not spilled outside the cartridge.

The device may have the following features:
The bottle has a lower threaded neck at its lower end and the cartridge has a threaded outer tubular sleeve extending along the cartridge axis toward the bottle, the lower threaded neck and the threaded outer tubular sleeve being designed to be threaded together during mounting of the cartridge onto the bottle.

Threaded attachment is an efficient and secure method of fastening bottles and cartridges.

According to an alternative embodiment,
the cartridge includes an inner tubular sleeve extending along a cartridge axis and a bottom wall, the inner tubular sleeve, the bottom wall, and the seal defining a cartridge reservoir;
the lower wall is movable between a lower position in which the cartridge reservoir has a first volume and an upper position in which the cartridge reservoir has a second volume, the first volume being greater than the second volume;
The cartridge includes an ejection mechanism for ejecting the second bulk into the bottle reservoir in the attached configuration, the ejection mechanism including a button for pushing the movable lower wall toward its upper position.

The presence of an injection mechanism allows the user to forcefully mix the first and second bulks to prepare the cosmetic product. The push button constitutes an easy to use and efficient mechanical system. The bottom wall acts as a piston that pushes the second bulk towards the bottle reservoir.

According to another alternative embodiment,
the seal comprises a cylindrical skirt covering at least a portion of an outer surface of the inner tubular sleeve;
the seal-opening mechanism includes a cutting edge designed to open the seal when the cartridge is placed in the installation configuration;
the seal is movable relative to the cutting edge between a first sealing position in which the seal seals the cartridge reservoir and a second opening position in which the bottle reservoir and the cartridge reservoir are in fluid communication by moving the cartridge between a disassembled configuration and an installed configuration;
The seal opening mechanism is supported by the cartridge;
The bottom end of the bottle is provided with a lower support designed to cooperate with the seal during mounting of the cartridge onto the bottle, thereby urging the seal towards its opening position.

The seal opening mechanism supported by the cartridge allows the user to operate the lightweight bottle. The seal is opened when the cartridge is mounted on the bottle. Thus, the seal is easily opened by the simple operation of the device.

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

By having the seal opening mechanism be part of the bottle's dispensing device, it becomes possible to implement a lightweight device in which the bottle and cartridge have a simple structure, without specific seal opening means, such as, for example, specific cutting edges.

In another variation, the ejection device is a pipette.

A pipette is a dispensing device that can be easily used by a user to draw cosmetic product from a bottle reservoir and dispense the cosmetic product, for example, onto a body surface.

According to another alternative embodiment, the device further comprises a removable bottle sealing plug designed to seal the bottom end of the bottle in the disassembled configuration, the removable bottle sealing plug being replaced with the cartridge in the installed configuration.

The removable bottle sealing plug constitutes a sealing means to prevent leakage of either the first bulk or the cosmetic product and the ingress of air into the bottle reservoir when the cartridge is, for example, in a disassembled configuration.

According to another alternative embodiment, the first bulk is a liquid and the second bulk is a powder.

The device offers a wide range of mixing possibilities. Different chemicals in different states can be used to prepare, for example, a customised cosmetic product adapted to the user's wishes.

According to another alternative embodiment, the device comprises at least an auxiliary cartridge, the auxiliary cartridge defining an auxiliary cartridge reservoir designed to contain an additional second bulk, the auxiliary cartridge reservoir extending between an auxiliary cartridge upper end and an auxiliary cartridge lower end of the auxiliary cartridge along the auxiliary cartridge axis, the auxiliary cartridge comprising an auxiliary seal sealing the auxiliary cartridge reservoir, the auxiliary cartridge being arranged in a disassembled configuration spaced apart from the bottle and in an attached configuration attached to the bottle, the seal opening mechanism being adapted to open the auxiliary seal when the auxiliary cartridge is arranged in the attached configuration, the bottle reservoir and the auxiliary cartridge reservoir being in fluid communication in the attached configuration, the auxiliary cartridge being mountable on the bottle in replacement with the cartridge, the auxiliary cartridge advantageously comprising a removable auxiliary cartridge sealing plug, the removable auxiliary cartridge sealing plug being designed to cover the auxiliary seal in the disassembled configuration, the removable auxiliary cartridge sealing plug being replaceable with the bottle in the attached configuration.

Several cartridges can be fitted in succession to the same bottle, for example to adjust the amount of second bulk in the final cosmetic product.

The invention will be better understood from the following description, given by way of example only, and with reference to the accompanying drawings, in which:

FIG. 2 is a cross-sectional view of a device according to the present invention showing a cross-sectional view of the bottle and cartridge, the cartridge being in an exploded configuration. 2 is a cross-sectional view of the device of FIG. 1, with the cartridge in an intermediate configuration between the disassembled configuration and the installed configuration. FIG. 2 is an enlarged cross-sectional view of the device of FIG. 1 showing the bottle bottom and cartridge, the cartridge in an attached configuration. FIG. 2 is a cross-sectional view of a variant of the device according to the invention showing a cross-sectional view of the bottle and cartridge, the cartridge being in an exploded configuration.

In the following, the term "top" is defined for a bottle as the direction of dispensing the first bulk or cosmetic product from within the bottle, and for a cartridge as the direction in which the cartridge is mounted on the bottle. The term "bottom" is defined as the direction opposite to the top direction.

A device 10 according to a first embodiment of the present invention is shown in Figures 1 to 3.

The device 10 is designed to package and dispense a cosmetic product prepared by mixing a first bulk with a second bulk.

The first bulk may be, for example, a liquid made up of chemical compounds, such as part of a cosmetic cream, lotion, serum, oil, etc.

The second bulk is, for example, a powder made up of compounds, which are part of an active formula, for example, an anti-aging active formula, a whitening active formula, a skin elasticity enhancing formula, etc.

The device 10 comprises a bottle 12 adapted to contain a first bulk, a cartridge 14 adapted to contain a second bulk in a sealed state, a dispensing device 16 for dispensing a mixture of the first bulk and the second bulk, and a seal opening mechanism 18 for opening the cartridge 14 when it is mounted on the bottle 12.

The device 10 may also include an auxiliary cartridge (not shown).

The bottle 12 has a tubular wall 20 and a removable bottle sealing plug 22.

The tubular wall 20 extends along the bottle axis B between the bottle lower end 24 and the bottle upper end 26.

The tubular wall 20 defines a bottle reservoir 28.

The bottle reservoir 28 extends along the bottle axis B between the bottle lower end 24 and the bottle upper end 26. The bottle reservoir 28 is designed to contain a first bulk or cosmetic product.

The tubular wall 20 has a lower threaded neck 30 at the lower bottle end 24 and an upper threaded neck 32 at the upper bottle end 26.

The lower threaded neck 30 and the upper threaded neck 32 each have a lower thread and an upper thread.

The upper threaded neck 32 has a free upper edge 38 and a circular mounting projection 40 extending upwardly from the free upper edge 38 along the bottle axis B.

The lower threaded neck 30 has a free lower edge 42. The free lower edge 42 has a lower support 44.

Referring to FIG. 1, the removable bottle sealing plug 22 comprises a threaded tubular skirt 50 and a bottle covering rounded wall 52.

The threaded tubular skirt 50 extends perpendicular to the bottle covering round wall 52.

The threaded tubular skirt 50 has plug threads that are complementary to the lower threads on the bottle bottom end 24.

The removable bottle sealing plug 22 is arranged in a covered configuration (as shown in FIG. 1) in which it is mounted on the lower threaded neck 30 of the tubular wall 20 and seals the bottle reservoir 28 at the bottle lower end 24, and in an uncovered configuration (as shown in FIGS. 2 and 3) in which it is spaced from the lower threaded neck 30 (the removable bottle sealing plug 22 is not shown in FIGS. 2 and 3).

The plug threads of the threaded tubular skirt 50 are configured to cooperate with the lower threads of the lower threaded neck 30 when the removable bottle sealing plug 22 is moved between the coated and uncoated configurations. In other words, the removable bottle sealing plug 22 and the bottle 12 are designed to be threaded onto one another during installation of the removable bottle sealing plug 22 onto the bottle 12.

The cartridge 14 includes a structural bulk reservoir 60, a removable cartridge sealing plug 62, and advantageously includes an ejection mechanism 64.

The structure 60 includes an outer tubular sleeve 68, an inner tubular sleeve 70, an annular joint 72 connecting the sleeves 68, 70, and a lower wall 74, which in this embodiment is formed by a piston 116 (described below). The structure 60 further includes a seal 76.

The outer tubular sleeve 68 extends along the cartridge axis C between the cartridge lower end 80 and the cartridge upper end 82. The outer tubular sleeve 68 defines a cylindrical cartridge cavity 84.

The outer tubular sleeve 68 has an inner surface oriented toward the cartridge axis C and an outer surface opposite the inner surface.

The outer tubular sleeve 68 has a thread. Specifically, the inner surface of the outer tubular sleeve 68 is provided with cartridge threads. The cartridge threads are complementary to the lower threads of the lower threaded neck 30 of the bottle 12.

The inner tubular sleeve 70 extends within the cartridge cylindrical cavity 84 along the cartridge axis C. The inner tubular sleeve 70 and the outer tubular sleeve 68 are coaxial.

The inner tubular sleeve 70 has an inner surface oriented toward the cartridge axis C and an outer surface opposite the inner surface of the inner tubular sleeve 70 and facing the inner surface of the outer tubular sleeve 68. The inner tubular sleeve 70 further has an inner tubular sleeve upper end 92, which is a free end.

The inner tubular sleeve 70 defines a cylindrical inner cavity 88.

The inner tubular sleeve 70 has a cutting edge 90 at the inner tubular sleeve upper end 92.

The cutting edge 90, for example, defines a spiral about the cartridge axis C.

The annular joint 72 extends from the outer surface of the inner tubular sleeve 70 to the inner surface of the outer tubular sleeve 68 in a plane radial to the cartridge axis C.

The annular joint 72 connects the outer tubular sleeve 68 and the inner tubular sleeve 70.

The annular joint 72 divides the cylindrical cartridge cavity 84 into an upper cylindrical cartridge cavity that extends above the annular joint 72 and a lower cylindrical cartridge cavity that extends below the annular joint 72.

The outer tubular sleeve 68 includes a lower portion defining a lower cylindrical cartridge cavity and an upper portion defining an upper cylindrical cartridge cavity. The upper portion of the outer tubular sleeve 68 includes a cartridge thread.

The lower wall 74 extends transversely through the cylindrical inner cavity 88 relative to the cartridge axis C and seals the cylindrical inner cavity 88 at the lower end of the lower wall 74.

The seal 76 includes a sealing rounded portion 96, a cylindrical skirt 98, and an annular abutment collar 100. The seal 76 seals the upper end of the inner tubular sleeve 70. The seal 76 seals the cylindrical inner cavity 88 from the upper end.

The sealing round portion 96 extends in a plane radial to the cartridge axis C. The sealing round portion 96 closes the seal upwards.

The cylindrical skirt 98 extends along the cartridge axis C and covers at least a portion of the outer surface of the inner tubular sleeve 70.

The annular abutment collar 100 extends radially from the cylindrical skirt 98 toward the outer tubular sleeve 68 within the annular space between the inner tubular sleeve 70 and the outer tubular sleeve 68. The annular abutment collar 100 is designed to cooperate with the bottle bottom end 24, as described further below.

The inner tubular sleeve 70, the lower wall 74, and the seal 76 define the cartridge reservoir 102.

The cartridge reservoir 102 is designed to contain a second bulk.

The seal 76 is movable along the cartridge axis C relative to the inner tubular sleeve 70 to open the sealing round portion.

The seal 76 is thus movable relative to the cutting edge 90 between a first sealing position in which the seal 76 seals the cartridge reservoir 102 and a second opening position in which the bottle reservoir 28 and the cartridge reservoir 102 are in fluid communication. Here, the seal 76 is frangible and configured to be broken by the cutting edge 90.

The cartridge 14 is arranged in a disassembled configuration in which it is separated from the bottle 12 and in an attached configuration in which it is attached to the bottle 12.

The lower threaded neck 30 of the bottle 12 and the threaded outer tubular sleeve 68 of the cartridge 14 are designed to be threaded together during installation of the cartridge 14 onto the bottle 12.

The annular abutment collar 100 of the seal 76 is designed to cooperate with the lower support portion 44 of the bottle 12 during installation of the cartridge 14 onto the bottle 12, thereby forcing the seal 76 into its opening position.

The removable cartridge sealing plug 62 is designed to cover the seal 76 in the disassembled configuration.

A removable cartridge sealing plug 62 replaces the bottle 12 in the mounting configuration.

A removable bottle sealing plug 22 replaces the cartridge 14 in the mounting configuration.

The removable cartridge sealing plug 62 comprises a cartridge covering rounded wall 110 and a straight tubular skirt 112.

The straight tubular skirt 112 protrudes perpendicular to the cartridge covering round wall 110.

The straight tubular skirt 112 has an inner diameter that is substantially equal to or less than the outer diameter of the outer tubular sleeve 68 of the cartridge 14.

The removable cartridge sealing plug 62 is arranged in a covered configuration mounted on the cartridge upper end 82 of the outer tubular sleeve 68 of the cartridge 14 and in an uncovered configuration spaced apart from the outer tubular sleeve 68.

In the covering configuration of the removable cartridge sealing plug 62, the straight tubular skirt 112 is designed to elastically deform and cooperate with the outer surface of the outer tubular sleeve 68 of the cartridge 14, thereby elastically mounting the removable cartridge sealing plug 62 to the outer tubular sleeve 68. The ejection mechanism 64 includes a piston 116, which constitutes the lower wall 74 of the cartridge 14, and a button 118, as described above.

The piston 116 extends at least partially within the cylindrical inner cavity 88 from the cartridge lower end 80 along the cartridge axis C.

The piston 116 has an upper surface that defines the lower wall 74 of the structural portion 60 of the cartridge 14. The piston 116 further has an outer surface that cooperates with the inner surface of the inner tubular sleeve 70.

The piston 116 is movable between a lower position in which the cartridge reservoir 102 has a first volume and an upper position in which the cartridge reservoir 102 has a second volume, the first volume being greater than the second volume.

As the piston 116 moves between its lower and upper positions, the outer surface of the piston 116 cooperates closely with the inner surface of the inner tubular sleeve 70, thereby guiding the piston within the cylindrical inner cavity 88.

The button 118 is designed to push the movable lower wall 74 toward an upper position. The button 118 includes a rounded support wall 122, a peripheral annular recess 124, and a support extension 126.

The rounded support wall 122 extends in a plane radial to the cartridge axis C. The rounded support wall 122 defines a pressing surface designed to be pressed by a user, in particular by the user's finger, to urge the movable lower wall 74 towards the upper position.

The peripheral annular recess 124 extends axially from the rounded support wall 122 along the cartridge axis C. The peripheral annular recess 124 is designed to cooperate with the lower portion of the outer tubular sleeve 68 when the button 118 is pressed by a user. Thus, the lower portion of the outer tubular sleeve 68 guides the button 118 when pressed by a user.

The support extension 126 extends axially from the rounded support wall 122 along the cartridge axis C toward the piston 116 and supports the piston 116. The support extension 126 is designed to push the piston 116 upward when the user pushes the rounded support wall 122 upward.

The dispensing device 16 is designed to dispense a first bulk or cosmetic product from the bottle reservoir 28.

The discharge device 16 includes a handling portion 130, an extension portion 132, a mounting sleeve 134, and a wiper 136.

The handling portion 130 is designed to be operated by a user, for example, to draw a first bulk or cosmetic product from within the bottle reservoir 28 and/or to dispense a first bulk or cosmetic product.

The handling section 130 comprises, for example, a deformable valve 140 and a tubular retaining wall 142. The deformable valve 140 is made of, for example, rubber.

The deformable valve 140 defines a retractable hollow cavity.

The tubular retaining wall 142 defines a retaining conduit that communicates with the retraction hollow cavity.

The tubular retaining wall 142 extends along the discharge device axis D.

The tubular retaining wall 142 includes an inner annular retaining recess 146, an outer annular retaining extension 148, and an outer annular retaining recess 150.

The inner annular retention recess 146 is defined, for example, on the inner surface of the retention conduit of the tubular retention wall 142.

The outer annular retention extension 148 extends radially outward from the free lower edge of the tubular retention wall 142.

The outer annular retention recess 150 is defined, for example, on the outer surface of the retention conduit of the tubular retention wall 142. The outer annular retention recess 150 is defined, for example, between the inner annular retention recess 146 and the outer annular retention extension 148 relative to the discharge device axis D.

The handling unit 130 is, for example, a valve of a pipette.

The extension 132 is a retraction means designed to extend within the bottle reservoir 28 substantially along the bottle axis B and along the dispenser axis D. The extension 132 comprises a conduit designed to extend within the bottle reservoir 28 substantially along the bottle axis B and the dispenser axis D between an extension upper end 154 attached to the handling portion and an extension lower end 156.

The extension upper end 154 is designed to be attached to the handling portion 130.

The conduit of the extension 132 extends at least partially within the retaining conduit of the tubular retaining wall 142.

The extension upper end 154 includes an annular retaining projection 160 extending radially away from the dispenser axis D. The annular retaining projection 160 engages the inner annular retaining recess 146 of the handling portion 130, thereby attaching the extension 132 and the handling portion 130.

The mounting sleeve 134 includes a tubular mounting sleeve 166 extending along the discharge device axis D between the mounting sleeve upper end and the mounting sleeve lower end.

The tubular mounting sleeve 134 includes an inwardly extending annular projection 168 at the upper end thereof for engaging with the outer annular retaining recess 150 of the handling portion 130, thereby attaching the mounting sleeve 134 to the handling portion 130.

The tubular mounting sleeve 134 includes a mounting sleeve thread that is complementary to the upper thread of the bottle top end 26.

The wiper 136 has an upper collar 172 and a lower collar 174.

The upper collar 172 is designed to cooperate with the circular mounting projection 40 on the tubular wall 20 to mount the wiper 136 to the tubular wall 20.

The upper collar 172 has an upper support surface 176.

The lower collar 174 is designed to extend inward toward the dispenser axis D and toward the bottle axis B.

The lower collar 174 is designed to wipe away any remaining first bulk of cosmetic product remaining on the outer surface of the extension 132 conduit.

The discharge device 16 is arranged in a retracting configuration mounted on the bottle top end 26 and in a discharge configuration spaced apart from the bottle top end 26.

The dispenser 16 and the bottle 12 are designed to be screwed together during installation of the dispenser 16 onto the bottle 12.

In the retracted configuration, the outer annular retention extension 148 of the handling portion 130 contacts the upper support surface 176 of the wiper 136.

In the retraction configuration, the first bulk or cosmetic product can be retracted by manipulating the handling portion 130.

In the dispensing configuration, a first bulk of the cosmetic product can be dispensed by manipulating the handling portion 130.

The ejection device 16 is, for example, a pipette.

The seal-opening mechanism 18 is adapted to open the seal 76 when the cartridge 14 is disposed in the mounted configuration. The bottle reservoir 28 and the cartridge reservoir 102 are in fluid communication in the mounted configuration.

As shown in Figures 1 to 3, the seal opening mechanism 18 is supported, for example, by the cartridge 14.

The seal opening mechanism 18 includes a cutting edge 90 on the cartridge 14.

The cutting edge 90 is designed to open the seal 76 when the cartridge is placed in the mounting configuration. In particular, the cutting edge 90 is designed to pierce the seal 76 during threading of the cartridge 14 onto the bottle 12.

The injection mechanism 64 is designed to inject the second bulk into the bottle reservoir 28 in the attached configuration, whereby the first bulk and the second bulk mix to form the cosmetic product.

Advantageously, the device 10 further comprises at least an auxiliary cartridge (not shown).

The auxiliary cartridge is structurally identical to the cartridge described above. The auxiliary cartridge reservoir of the auxiliary cartridge contains, for example, a second bulk or a third bulk different from the second bulk.

The auxiliary cartridge can be installed on the bottle 12 in place of the cartridge.

The use of device 10 to prepare and dispense a cosmetic product is described below.

Referring to FIG. 1, the device 10 described above is shown. The cartridge is in its exploded configuration. The removable bottle sealing plug 22 is in its covered configuration. The removable cartridge sealing plug 62 is in its covered configuration. The discharge device 16 is in its retracted configuration. The seal 76 is in its sealed configuration. The piston 116 is located in its lower position.

The removable cartridge sealing plug 62 is removed from the structural portion 60 of the cartridge 14 to provide an uncoated configuration of the removable cartridge sealing plug 62.

The removable bottle sealing plug 22 is removed from the bottle tubular wall 20 to provide an uncovered configuration of the removable cartridge sealing plug 62.

The cartridge 14 is then screwed onto the lower threaded neck 32 of the bottle 12 to form an attachment configuration for the cartridge 14.

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

Press button 118 to place it in its top position.

The first bulk is mixed with the second bulk. The first bulk and the second bulk form a cosmetic product.

Operate the handling portion 130 to draw the cosmetic product from within the bottle reservoir 28 into the conduit of the extension portion 132.

Then, remove the discharge device 16 from the bottle 12 and set the discharge device 16 to the discharge 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.

The present invention provides a safe and optimal adjustment of the first and second bulks. The device allows the user to prepare a cosmetic product as desired and tailored to their taste, with the bulk protected from degradation. In particular, the present invention prevents air from entering the cartridge reservoir, thereby protecting the active ingredients therein.

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

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

In particular, the inner tubular sleeve 70 includes an annular sealing recess 180. The seal 76 includes an annular sealing projection 182 designed to engage the annular sealing recess 180 and secure the seal 76 with the inner tubular sleeve 68.

In this second embodiment, the button 118 is also the piston 116. 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 a user. The inner surface of the inner tubular sleeve 70 thus guides the button 118 when the button 118 is pressed by a user.

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

In particular, the lower pressing end is designed to press the seal 76 downward during installation of the cartridge 14 onto the bottle 12, thereby disengaging the annular sealing projection 182 from the annular sealing recess 180. The seal 76 is then free to move relative to the inner tubular sleeve 70, and is positioned in its open position. The bottle reservoir 28 and the cartridge reservoir 102 are then in fluid communication.

According to a second embodiment of the present invention, the circular mounting projection 40 extends radially from the bottle top end 26 toward the bottle axis B.

According to a variant, the second bulk is liquid.

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