Description

Dispenser of a fluid product, associated refill and associated receptacle

Technical field of the invention

The invention relates to a dispenser for a fluid product configured to be reversibly mounted on a fluid product reservoir.

The invention also relates to a fluid product refill on which such a dispenser can be mounted.

The fluid product is of the lotion, gel, perfume, serum or cream type for example, used for cosmetic purposes or for pharmaceutical treatments.

Technical background

It is known, in the field of cosmetic and pharmaceutical packaging, to provide receptacles intended to carry cosmetic products, said receptacles comprising a reservoir on the one hand, and a head, on the other hand equipped with a means of collection and distribution. Often, the head and the reservoir form a nomadic, self-sufficient distributor.

When it is empty or its contents have become unusable, the entire receptacle is generally thrown away.

Such a design can pose economic problems, on the one hand, and environmental problems, on the other hand.

First of all, depending on the materials used and its degree of finish, the cost of the receptacle can represent a significant proportion of the purchase price.

In addition, the number of materials used, the techniques for assembling the different components together and the decoration techniques implemented do not make it possible to recycle all of the materials used to manufacture the receptacle in the same recycling chain.

One solution to this problem is the use of a so-called “interchangeable” receptacle.

In comparison with a single-use receptacle, such a receptacle is characterized by being refillable, that is to say designed to allow changing of the reservoir, in particular but not exclusively after complete use of the fluid product.

The interchangeability of the receptacle also makes it possible to use, independently of full use, a head with several reservoirs each comprising, for example, a different fluid product.

Such a design makes it possible to maintain a head which can include a complex sampling and dispensing mechanism, a cover and/or an outer sheath which is particularly advantageous when these parts are made of precious materials and/or decorated, for example covered of a covering, which by comparison makes them more expensive to manufacture and/or difficult to recycle.

In such a receptacle, the interchangeable part constitutes in particular a refill which can be changed freely.

Not only do current refill examples consist of complex examples with many parts, but very often changing the refill is complicated, even messy.

There is therefore a need for a solution making it possible to resolve at least part of the disadvantages of the prior art while maintaining an assembly which is interchangeable and advantageously simple and economical to manufacture.

Thus, the invention relates to a distributor of a fluid product configured to be removably mounted on a reservoir of fluid product, the distributor comprising a head and a distribution body, the head being removable relative to the distribution body, the head comprising selection means, actuation of which causes an axial movement of an intermediate ring and blocking and/or unlocking in rotation between the intermediate ring and the distribution body.

In other words, the selection means makes it possible to actuate the intermediate ring so that its axial movement, that is to say its rise and/or its descent, prevents and/or authorizes the rotation of the intermediate ring relative to the body. of distribution.

Thus, when the rotation between the intermediate ring and the dispensing body is blocked, the user can, for example, unscrew the dispenser mounted on the reservoir so as to collect and/or distribute the cosmetic product.

On the other hand, when rotation is authorized between the intermediate ring and the distribution body, the user cannot open the tank by a rotational movement. The rotational movement will, however, allow other functions, such as, for example, the separation and/or assembly of the distribution head and body.

Detailed description of the invention

By convention, the "axial" direction corresponds in the figures to that of the main axis is orthogonal to the axial direction.

In the detailed description of the figures which follows, the terms “upper” and “lower” or “top” and “bottom” will be used in a non-limiting manner with reference to the axial direction.

Similarly, the terms "outer or outer" and "inner or inner" are used in reference to the radial direction, with an outer element being radially further from the X axis than an inner element.

There illustrates a fluid product receptacle 14 comprising a distributor 10 mounted removably/reversibly on a reservoir 12, the distributor 10 being in different positions.

By “removable”, “reversible” is meant the fact that the reservoir 12 is equipped with the distributor 10 with the possibility of removing it, particularly when dispensing the fluid product, without causing destruction or deformation of one of the two elements.

The fluid product is of the lotion, gel, perfume, or cream type for example, used for cosmetic purposes or for pharmaceutical treatments.

The distributor 10 comprises, in its upper part, a head, here an actuating head 16 and in its lower part, a distribution body 18. The removable connection between the distributor 10 and the reservoir 12 is made via the distribution body 18.

The actuation head 16 is configured to be reversibly mounted on the dispensing body 18. When the actuation head 16 is detached from the dispensing body 18, then the assembly formed by the reservoir 12 and the dispensing body 18 forms a refill 20. In other words, the refill 20 is intended to be removably mounted with the actuating head 16 to constitute the distributor 10 mounted on the reservoir 12.

By “removable” we mean the fact that the refill 20 is equipped with the actuating head 16 with the possibility of removing it, without causing destruction or deformation of one of the two elements. Thus, the refill 20 is intended to be able to be changed, in particular but not exclusively after the fluid product has been completely used.

In this embodiment, the actuating head 16 is fixed to the refill 20 by a bayonet type system. . More precisely, the actuating head 16 is fixed to the distribution body 18 by a bayonet type system.

The actuation head 16 comprises three lugs 21 cooperating with three L-shaped notches 22, located on an exterior surface of the refill 20, in particular on an exterior surface of the dispensing body 18. The connection between the head of actuation 16 and recharging 20 is then carried out by a translation movement then rotation of one and/or the other.

An example of producing a refill 20 with the actuating head 16 detached is illustrated in .

In this exemplary embodiment, the refill 20 has a main axis X' which extends in the axial direction, merging with the main axis receptacle 14.

Refill 20 includes:

- the reservoir 12 configured to contain the fluid product, and

- the distribution body 18.

The distribution body 18, visible at the understand :

- a pipette 23,

- a closing system ensuring the sealing of the tank 12 when the distribution body 18 is mounted on the tank 12, and

- a lower piston 24.

In this embodiment, the sampling means is the pipette 23 of the dispensing body.

The pipette 23 is configured to allow storage of fluid product with a view to being distributed and to be housed inside the reservoir 12.

In other embodiments not illustrated, the sampling means can be a plunging applicator, a rod equipped at a first axial end with an applicator tip. The applicator tip can be, for example, an applicator tip for mascara, gloss and/or varnish, a brush.

The reservoir 12 is configured to contain the fluid product and receive the pipette 23.

The closure system ensures the sealing of the reservoir 12 when the pipette 23 is housed in it.

The tank 12 comprises a longitudinal wall 26 and an upper opening. The longitudinal wall 26 delimits an internal volume in which the fluid product can be stored. The upper opening is delimited by a neck 28 connected to the longitudinal wall 26 by a frustoconical shoulder.

The reservoir 12 is here associated with a closing ring 30 configured to be removably fixed to the reservoir 12.

To do this, the closing ring 30 comprises closing means 32, 34 cooperating with closing means of the reservoir 12.

The closing means 32 of the closing ring 30 are located on an internal surface of an external wall 36 defining an internal housing.

The closing means 34 of the reservoir 12 are located on an external surface of the neck 28.

This is a threading system 32, 34. The closing ring 30 can thus be fixed and/or removed from the tank 12 by a rotational movement of one relative to the other.

The closing ring 30 also includes, in this embodiment, the three L-shaped notches 22 allowing the connection of the actuating head 16 to the refill 20. The L-shaped notch 22 is in particular located on a external surface of the external wall 36 of the closing ring 30.

The outer wall 36 of the closing ring 30 defines in particular the internal housing in which the lower piston 24 is mounted.

In this embodiment, the internal housing further comprises an internal skirt 38 into which the lower piston 24 is inserted.

In this exemplary embodiment, the internal skirt 38 is also extended by the pipette 23. Thus, the internal skirt 38 forms a storage chamber 40 in fluid connection with the pipette 23, storage chamber 40 in which the lower piston 24 slides . More precisely, the lower part of the internal skirt 38 is connected to an upper end of the pipette 23. An opposite lower end of the pipette 23 is open and configured to be immersed in the reservoir 12 when the closing ring 30 is mounted on the reservoir 12. The fluid connection between the storage chamber 40 and the pipette 23 is closed when the lower piston 24 is in the lower position inside the storage chamber 40.

The pipette 23 allows the storage of the dose of fluid product taken for distribution.

The closing ring 30, the internal skirt, the pipette 23 and the lower piston 24 form part of the distribution body 18.

Advantageously, the lower piston 24 ensures a watertight seal to the tank 12.

The lower piston 24 is thus a sealing means cooperating with the closing ring 30 so as to ensure the watertight closure of the tank 12. Thus, when the distribution body 18 is mounted on the tank 12, the refill 20 thus constituted is waterproof.

The actuating head 16 comprises an actuator 42, an upper piston 44 and a connecting ring 46 allowing the connection between the actuator 42 and the closing ring 30 of the distribution body 18.

In other words, the connecting ring 46 makes it possible to fix the actuating head 16 to the distribution body 18 via the closing ring 30 thereof. Preferably, the connecting ring 46 is mounted reversibly on the closing ring 30 so that the actuating head 16 is removable relative to the distribution body 18.

Advantageously, the closing ring 30 and the connecting ring 46 are linked in rotation, as well as axially. In other words, the closing ring 30 and the connecting ring 46 are fixed relative to each other when the actuating head 16 is connected to the distribution body 18.

On the other hand, the actuator 42 is movable in axial translation relative to the connecting ring 46.

The connecting ring 46 further comprises an upper internal skirt 48 forming a housing in which the upper piston is housed.

In this embodiment, the actuating head 16 further comprises an outer sheath 50 linked in rotation with the actuator 42 via the connecting ring 46 and enveloping the connecting ring 46.

The outer sheath 50 makes it possible in particular to conceal the various parts allowing the sampling and distribution of the fluid product.

In this embodiment, the dose of product is taken by an axial translation movement of the actuator 42. This axial translation movement can be obtained by axial pressure on the actuator 42 as in the example shown here.

Preferably, the actuator 42 is a push button.

The axial pressure causes a movement of the lower piston 24 and the upper piston 44. The lower piston 24 and the upper piston 44 are linked in translation and together form a piston assembly 51.

The piston assembly 51 is movable in vertical translation in the storage chamber 40. Its vertical translation upwards or downwards causes the sampling and/or distribution of the fluid product. In other words, the vertical translation movement of the piston assembly 51 allows the sampling and/or distribution of the fluid product,

Preferably, the lower piston 24 is configured to be irreversibly mounted on the distribution body 18 and the upper piston 44 is configured to be irreversibly mounted on the actuating head 16.

The piston assembly 51 comprises connecting means making it possible to connect the lower piston 24 and the upper piston 44 in translation.

In a first assembly variant, the connecting means can be, for example, a bayonet system as illustrated in .

In such a bayonet system, the lower piston 24 comprises, for example, at least one notch 88, for example L-shaped, and the upper piston 44 comprises at least one tenon 90 (or vice versa) cooperating with the notch 88. connection between the lower piston 24 and the upper piston 44 is then carried out by a movement of translation then rotation of one and/or the other of the lower and

upper pistons

24, 44.

In this first assembly variant illustrated in , the lower piston 24 comprises two L-shaped notches 88 and the upper piston 44 comprises two tenons 90 projecting radially. Each of the tenons 90 cooperates with a notch 88 so that the lower piston 24 and the upper piston 44 are linked axially and in rotation and that an axial translation movement of one causes the axial translation of the other and the sampling and/or the distribution of a dose of fluid product.

In this assembly variant, the notches 88 have a horizontal ramp 88a extending annularly and a vertical ramp 88b opening through an upper opening 88c at the level of the upper end of the lower piston 24.

When mounting the actuating head 16 on the distribution body 18, each of the tenons 90 is inserted at the level of the upper opening 88c. Then a vertical translation movement downwards, followed by a rotational movement allows the assembly of the lower piston 24 with the upper piston 44. The lower piston 24 and the upper piston 44 are thus linked axially and in rotation so that an axial translation movement of one causes the axial translation of the other and the sampling and/or distribution of a dose of fluid product.

In a second assembly variant, the connecting means are a snap-lock system as illustrated in Figures 10 to 15.

In this second alternative embodiment, the lower piston 24 comprises two opposite through openings 100 and the upper piston 44 comprises two opposite tenons 102 projecting radially. Each of the tenons 102 cooperates with one of the openings 100 so that the lower piston 24 and the upper piston 44 are linked axially and in rotation and that an axial translation movement of one causes the axial translation of the other and the collection and/or distribution of a dose of fluid product.

During assembly, the upper piston 44 is forced into the lower piston 24 to engage it.

To improve the connection in rotation, the upper piston 44 comprises a lower rod 104 comprising two flats 106 which are housed in a lower rectangular cavity 108 of the lower piston 24 as visible at the . The lower cavity 108 is thus of complementary shape to the cross section of the lower rod 104 of the upper piston 44.

In this third assembly variant, the lower piston 24 comprises two radial and opposite external projections 110 which each cooperate with an internal L-shaped notch 112 located on the internal surface of the internal skirt 38 of the closing ring 30.

The L-shaped notch 112 makes it possible to guide the lower piston 24 in translation by sliding the external projections 110 in the notch 112, in particular in a vertical ramp 112a of the notch 112.

Advantageously, the external projections 110 are aligned with the vertical ramp 112a after the lower piston 24 is made a quarter turn.

Preferably, the quarter turn is induced by a rotation of the actuating head 16.

The L-shaped notch 112 further comprises a horizontal ramp 112b which makes it possible to form a space allowing spacing of the upper part of the lower piston 24 and facilitate its assembly with the upper piston 44.

Once the lower piston 24 is housed in the storage chamber 48, the upper part of the lower piston 24 can no longer move apart, thereby maintaining the assembly between the lower piston 24 and the upper piston 44.

The external radial projections 110 and the through openings 100 are angularly regularly distributed. In other words, they form 90 degree angles between them.

The piston assembly 51 further comprises a washer 114.

Advantageously, before the first use, the washer 114 is connected to the lower piston 24 on its upper part by at least one breakable bridge 116. In this embodiment, the washer 114 is connected by two opposite breakable bridges 116.

During the first use and/or when fixing the actuating head 16 on the refill 20, an axial pressure made by the user causes a downward translation movement of the lower piston 24 while the washer 114 remains in place in the top of the internal skirt 38 of the closing ring 30, blocked by a shoulder 118. The breakable bridges 116 are then broken, releasing the downward translation movement of the lower piston 24.

The washer 114 makes it possible to maintain the lower piston 24 in the internal skirt 38 of the closing ring 30. Indeed, during the translational movement of the lower piston 24, the external projections 110 come into abutment on the lower surface of the washer 114. The lower piston 24 is thus held in the internal skirt 38 of the closing ring 30.

The washer 114 is itself blocked in upward translation by hooking zones 120 located in the upper part on the internal surface of the internal skirt 38 of the closing ring 30.

The washer 114 is thus mounted fixed, in particular in axial translation in the internal skirt 38 of the closing ring 30.

Thus when actuated, the lower piston 24 can move up and down driven by the upper piston 44 while the washer 114 is fixed in the internal skirt 38 of the closing ring 30.

The release causes the piston assembly 51 to rise, causing the product to rise in the pipette 23 up to the storage chamber 40 defined in the housing of the closing ring 30 and delimited in the upper part by the bottom of the lower piston 24.

Another vertical translation movement of the actuator 42, such as a new axial pressure on the actuator 42, allows the distribution of the fluid product stored in the pipette 23 and/or the storage chamber 40.

This other axial pressure causes a new movement of the piston assembly 51 and the distribution of the fluid product.

Advantageously, the actuating head 16 comprises a return means so that the actuator 42 returns to a position of use after actuation. As in the example shown here, it may be a helical spring 52 located between the upper internal skirt 48 of the connecting ring 46 and a side wall 54 of the actuator 42.

Advantageously, a movement of the actuator 42, in particular a translation movement, causes actuation of the piston assembly 51 to allow the sampling and/or distribution of the dose of fluid product.

According to the invention, the distributor 10 comprises a selection means, actuation of which causes an axial movement of an intermediate ring 70 and a locking and/or unblocking in rotation between the intermediate ring 70 and the distribution body 18.

In other words, the selection means makes it possible to actuate the intermediate ring 70 so that its axial movement, that is to say its rise and/or its descent, prevents and/or authorizes the rotation of the intermediate ring 70 relative to to the distribution body 18.

Thus, when the rotation between the intermediate ring 70 and the distribution body 18 is blocked, the user can unscrew the closing ring 30 mounted on the refill tank 20 by rotating the actuating head 16. In other words, the actuating head 16 and the distribution body 18 are integral in rotation when the rotation between the intermediate ring 70 and the distribution body 18 is blocked. In other words, the user can open the receptacle 14 so as to collect and/or distribute the cosmetic product.

On the other hand, when rotation is authorized between the intermediate ring 70 and the distribution body 18, the user cannot open the receptacle 14 by a rotational movement of the actuating head 16. The rotational movement will however allow other functions, such as, for example, the separation of the actuation head from the refill 20 and/or the assembly of the actuation head on the refill 20.

Preferably, the selection means is a selection ring 56 visible at the .

In the embodiment illustrated here, the actuation of the selection means is a rotation. In other words, the rotation of the selection ring 56 causes the axial movement of the intermediate ring 70.

This transformation of movement is obtained by a system of cam trajectory(s) 72 and cam follower(s) 74.

In the embodiment illustrated here, the intermediate ring 70 comprises three cam trajectories 72 cooperating with three cam followers 74 of the selection ring 56 so as to transform the rotational movement of the actuating head 16 into axial movement of the intermediate ring 70.

The cam followers are three studs 74 regularly distributed on an internal surface of a transverse wall 58 of the selection ring 56.

The cam trajectories are through openings 72 located on a side wall 76 of the intermediate ring 70 and regularly distributed.

Each of the cam trajectories 72 comprises an upper portion 72a and a lower portion 72b connected by an oblique portion 72c. Thus the rotation of the selection ring 56 causes the rotational movement of the studs 74 which follow the trajectory of cam 72 and allow the raising and lowering of the intermediate ring 70.

The intermediate ring 70 is in the high position when the studs 74 are located in the lower portion 72b of the cam trajectories 72.

The intermediate ring 70 is in the low position when the studs 74 are located in the upper portion 72a of the cam trajectories 72.

The intermediate ring 70 is further provided with three tongues 78 extending downwards from the side wall 76. The tongues 78 are regularly distributed and are located between the cam trajectories 72.

The tongues 78 cooperate with three recesses 80 located regularly distributed on a transverse wall 82 of the closing ring 30.

Thus, when the intermediate ring 70 is in the low position, the three tongues 78 of the intermediate ring 70 are housed in the three recesses 80 of the closing ring 30 ( ). The rotation between the intermediate ring 70 and the distribution body 18 is blocked.

On the other hand, when the intermediate ring 70 is in the high position, the three tongues 78 of the intermediate ring 70 come out of the three recesses 80 of the closing ring 30 ( ). Rotation between the intermediate ring 70 and the distribution body 18 is then possible.

The three tongues 78 are first means for blocking rotation between the actuating head 16 and the closing ring 30. The three recesses 80 are second means for blocking rotation between the actuating head 16 and the closing ring 30.

The tongues 78 also cooperate with through openings 84 located on a transverse wall 86 of the connecting ring 46. The tongues 78 thus make it possible to connect the connecting ring 46 and the intermediate ring 70 in rotation.

As mentioned previously, in this embodiment, the actuating head 16 is attached to the refill 20 by a bayonet type system. More precisely, the actuating head 16 is fixed to the distribution body 18 by a bayonet type system.

Thus, the actuating head 16, and more precisely the connecting ring 46, comprises the three lugs 21 cooperating with the three L-shaped notches 22, located on an exterior surface of the distribution body 18, and more precisely on the wall side of the closing ring 30.

The notches 22 comprise a horizontal portion 22a and a vertical portion 22b opening onto the transverse wall 82 of the closing ring 30.

When the lugs 21 are located in the horizontal portion 22a, the actuating head 16 and the refill 20 are linked axially. On the other hand, when the lugs 21 are located in the vertical portion 22b, a vertical movement upwards of the actuating head 16 allows them to exit the notches 22 and the disassembly of the actuating head 16 from the refill 20.

The connection between the actuating head 16 and the refill 20 is then carried out by a downward translation movement then rotation of one and/or the other. In other words, the rotation of the actuating head causes an axial blocking and/or unblocking between the actuating head 16 and the dispensing body 18.

Thus, by actuation of the selection ring 56, in particular by rotation, the user can disassemble and/or assemble the actuation head 16 and the distribution body 18.

In the embodiment shown here, this means that the user can separate the actuation head 16 from the refill 20 and/or fix the actuation head 16 on the refill 20 by a rotational movement of the head. actuation 16, and more precisely of the selection ring 56.

Advantageously, each of the lugs 21 is of different dimensions and each of the notches 22 is of different width. Thus the width of the notches 22 is adapted to the dimension of the lug 21 which is intended for it. This makes it possible to have a single angular assembly position between the actuating head 16 and the refill 20.

This can also be used for coding, that is to say an actuating head 16 can be assembled with a single refill 20.

Advantageously, in the embodiment illustrated here, the relative positioning of the selection means, here of the selection ring 56, relative to the actuator 42 results in a choice of the stroke height of the actuator 42 between least two different running heights. The actuator 42 is movable in translation relative to the selection means.

In other words, the selection ring 56 makes it possible to modify the stroke height of the actuator 42 and thus modify the quantity of fluid product taken and to define a dose of fluid product.

In this embodiment, the selection ring 56 is rotatable relative to the actuator 42. Thus, the stroke height is chosen by rotation of the selection ring 56 relative to the actuator 42.

The internal surface of the side wall 58 of the selection ring 56 is further provided with two first diametrically opposed stops 60.

The selection ring 56 is located, concentrically, between the actuator 42 and the connecting ring 46. In other words, the actuator 42 is housed in the selection ring 56, that is to say the selection ring 56 envelops the actuator 42.

Thus, the two first stops 60 located on the internal surface of the side wall 58 of the selection ring 56 cooperate with a plurality of second stops 62a, 62b, 62c located on an external surface of the side wall 54 of the actuator 42 located at different heights so as to define different travel heights for the actuator 42.

Indeed, depending on the position of the selection ring 56 relative to the actuator 42, the first stops 60 thereof come into vertical abutment with the second stops 62a, 62b, 62c of the actuator 42 after a different stroke height.

In other words, the rotation of the selection ring 56 makes it possible to define the stroke height by cooperation between the first stops 60 and one of the second stops 62a, 62b, 62c.

The selection ring 56 further comprises a selection cursor 66 making it possible to indicate in which position the actuating head 16 is located. When rotating the selection ring 56, the user aligns the selection cursor with the desired position. The different positions (here blocking, large dose, small dose) are indicated, for example, on the outer sheath 50 of the actuating head 16 which includes position indications 68 of the actuating head 16, as illustrated here.

The blocking position corresponds to the position in which the actuating head and the refill 20 can be disassembled; The lugs are located in the vertical portion of the notches, so that they can be removed completely.

Advantageously, the refill 20 is made of a single material.

In other words, the reservoir 12 and the dispensing body 18 (the closing ring 30, the internal skirt, the pipette 23 and the lower piston 24) are made of the same material, or at least of similar materials.

By similar materials we mean materials which will have at least one common recycling circuit.

The use of the same material, or at least similar materials, to make the different parts of the refill 20 is particularly interesting for their recycling after use of the fluid product. Indeed, the presence of different materials presents disadvantages during recycling where the parts must be separated. The use of the same material allows all the parts of the refill 20 to be thrown away together without having to dismantle it, which facilitates recycling.

The material can be chosen from polypropylene (PP), polyethylene terephthalate (PET), recycled polyethylene terephthalate (R-PET), a thermoplastic elastomer (TPE), polyethylene (PE), such as low density polyethylene (LDPE). ) and/or high density polyethylene (HDPE), a composite material, a post-consumer recycled material (PCR) and/or a similar material.

Preferably, the material is selected from polypropylene, polyterephthalate, post-consumer recycled polypropylene, post-consumer recycled polyterephthalate, or a mixture thereof.

Polypropylene and polyethylene terephthalate are two plastic materials whose recycling cycle is well known.

The tank 12 may also be made of glass, wood, metal, plastic, hybrid material or mixtures thereof.

The disassembly of the actuating head 16 and the dispensing body 18 and the disassembly of the dispensing body 18 and the reservoir 12 being easily carried out, the fact that the reservoir 12 is made of a different material does not complicate recycling, each of the parts being recycled in a clean recycling cycle.

In another embodiment not illustrated, the distributor 10 may include a cover.

The cover is intended to cover the actuating head 16.

Preferably, the cover is removable. The cover is capable of occupying at least one open position in which the cover is separated from the actuating head 16 with a view in particular to allowing the actuation of the distributor 10 and the sampling and/or distribution of the fluid product and a closed position in which the cover is secured to the actuating head 16.
