Description

Title of the invention: Cosmetic product dispenser pot with anti-residual means Technical field of the invention

[0001] The invention relates to a cosmetic product dispenser pot, of the fluid product type. This pot comprises product dispensing means for delivering identical doses of product each time a wheel is actuated. This pot also comprises anti-residual means to prevent product from continuing to come out after the wheel has been actuated.

[0002] The invention also relates to a method of dispensing a cosmetic product from such a pot.

[0003] The cosmetic product is fluid, of the cream type. Technical background

[0004] We know about cosmetic product dispenser pots, which allow doses of fluid product to be delivered.

[0005] In general, these pots are equipped with a variable volume chamber, containing the product. A piston, actuated by a mechanical system, compresses the chamber to force the escape of a dose of product via a dispensing orifice.

[0006] One of the disadvantages is that the dispensed dose differs from one dose to another depending on the actuation movement made by the user on the mechanical system. In addition, product may continue to come out of the orifice once the actuation is complete, because a phenomenon known as "remanence" occurs. This excess product, released after the user has already taken their dose of product, may stagnate around the outlet orifice, and thus be contaminated by bacteria present in the environment or on the user's finger. Summary of the invention

[0007] The present invention aims to overcome the various drawbacks stated above, by means of a cosmetic product dispenser pot, provided with product dispensing means, which are easily actuated by the user, and which make it possible to deliver an identical dose of product repeatedly, without any residual effect, and while preserving the intrinsic properties of the product contained inside the pot by preventing any contact between the product and the user's fingers.

[0008] This pot must be simple to manufacture, with a minimum of parts, and with a view to easy recyclability.

[0009] This goal is achieved by means of a cosmetic product dispenser pot having an axis Central X and mainly comprising four rooms, namely:

[0010] - a hollow cylindrical body partly defining a variable volume chamber for storing product, closed at one end by an upper wall having a product dispensing orifice;

[0011] - a wheel for actuating the product distribution, said wheel having a threaded rod extending along the X axis and passing through the body, the wheel and the body being mounted to be movable in rotation relative to each other, the wheel also being movable in translation along the X axis relative to the body between an initial position and a raised position, and vice versa;

[0012] - a piston screwed onto the rod and in sealed contact with the body, the piston forming a bottom to said chamber, the piston being movable in translation along the X axis within the body by rotation of the rod via the wheel, so as to vary the volume of the chamber;

[0013] - a valve for sealing the distribution orifice.

[0014] The pot is mainly characterized in that said valve is mounted on a free end of the rod and is integral with the translational movement of the wheel, the valve thus being movable in translation along the X axis between a closed position, against the upper wall of the body, where the dispensing orifice is closed, and an open position, at a distance from the upper wall of the body, where the dispensing orifice is open.

[0015] The main idea of ​​this invention is to provide a pot with a wheel that moves axially relative to the body, over small axial strokes (between the initial position and the raised position) which allow the dispensing orifice to be opened and closed by the valve. Thus the opening and closing of the dispensing orifice are dependent on the actuation of the wheel by the user. However, they are independent of the pressure inside the chamber. This has the effect of automatically closing the dispensing orifice as soon as the actuation of the wheel is complete, and not as a function of the pressure in the chamber. Thus, whatever the pressure in the chamber, product can no longer escape through the dispensing orifice. In addition, since the piston is screwed to the rod, the piston descends back into the body when the wheel moves from its raised position to its initial position, increasing the volume of the chamber.This sudden increase in volume has the effect of decompressing the chamber and stopping the pressure of the product in the vicinity of the dispensing orifice, thus preventing any residual effect.

[0016] There is no excess product overflowing from the orifice after actuation. The dose of product delivered can be collected by the user, after actuation, by passing his finger over the upper wall of the body. After collecting this dose of product, the upper wall of the body remains clean all around the orifice because there is no more product coming out. There is less risk of contamination of the product inside the jar.

[0017] This pot is easy to use, because the user holds the body in one hand, and operates the wheel in the other hand by turning it.

[0018] This pot has a simplified design, as only four parts are required for its operation.

[0019] According to the different embodiments of the invention, which may be taken together or separately: - the pot includes a cam and cam follower system, for the rotational and translational movement of the wheel relative to the body, with an axial return to the initial position of the wheel after each rotary actuation of the wheel. - said system consists of cooperation between a cam formed by a circumferential ramp of the body provided with notches, and a cam follower formed by at least one pin projecting from the wheel, said pin sliding on the ramp, the passage of the pin over a notch operating an axial return to the initial position of the wheel. - the ramp is discontinuous, and formed by sections of ramp connected by returns forming the notches, all the notches being located on the same axial reference of the X axis. - with each rotary actuation of the wheel, the wheel moves in translation relative to the body from an initial position to a raised position as long as the pins slide on the ramp sections, then from the raised position to the initial position when the pins slide on the returns, marking the end of the dispensing of a dose of product. - the cam follower is formed by two diametrically opposed pins. - one operation of the wheel corresponds to one rotation on one sector 45° angle. - the movement of the wheel in translation from its initial position to its raised position, and vice versa, causes the valve to move in translation from its closed position to its open position, and vice versa. - the pot also includes a lid for closing the pot, having means for pressing on the valve forcing the valve to remain in the closed position when the lid is mounted on the body. - the pot is made of a single material. - the pot has spring means between the body and the wheel, forcing the wheel to return to the initial position after each actuation.

[0020] The invention also relates to a method for dispensing a cosmetic product. from a pot as previously described, comprising the following steps: - turn the wheel relative to the body on an angular portion corresponding to a section of the ramp of the body, which simultaneously causes: • on the one hand a translation of the wheel from an initial position to a raised position, which causes a translation of the valve from a closed position to an open position, which causes the opening of the distribution orifice by moving the valve away from the body; • on the other hand a translation of the piston within the body in the direction of the valve, which causes a reduction in the volume of the chamber with compression, which causes a dose of product to escape through the dispensing orifice; - continue to turn the wheel relative to the body until the detection of the passage of a notch following a ramp section, which causes a translation of the wheel from its raised position to its initial position, which causes a closing of the distribution orifice by the valve, and which causes a translational movement of the piston within the body away from the valve, which causes an increase in the volume of the chamber with decompression. Brief description of the figures

[0021] Other characteristics and advantages of the invention will appear during the reading of the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:

[0022] [Fig.l] is a general view, in perspective, of a pot according to the invention, closed with its lid.

[0023] [Fig.2] is a general perspective view of the pot without its lid.

[0024] [Fig.3] is an exploded view of the pot according to a first configuration.

[0025] [Fig.4] is a sectional view of the pot according to [Fig.3].

[0026] [Fig. 5] is an exploded perspective view of a pot according to a second confi guration.

[0027] [Fig.6] and a sectional view of the pot according to [Fig.5]. Detailed description of the invention

[0028] In the remainder of the description, elements having an identical structure or similar functions will be designated by the same references.

[0029] By convention, the “axial” direction corresponds to that of the main extension of the receptacle, illustrated by the X axis in [Fig.l], and the “radial” direction is orthogonal to the axial direction.

[0030] 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. Thus, the term “upper” means a part located in the vicinity of a cover 4 of the pot 1, and the term “lower” means a part located in the vicinity of a bottom of the pot 1.

[0031] Similarly, the terms "outer or external" and "inner or internal" are used with reference to the radial direction, an outer element being radially further from the X-axis than an inner element.

[0032] The cosmetic product dispenser pot 1 shown in [Fig. 1] is mainly made up of a body 2 mounted on a wheel 3 and topped with a lid 4.

[0033] In the present invention, the cover 4 is not mandatory.

[0034] This cosmetic product preferably consists of a fluid product, such as a foundation cream. By fluid product is meant a more or less viscous product, which is not solid.

[0035] The cosmetic product is stored in a chamber 10 provided for this purpose in the body 2, and visible in [Fig.4].

[0036] A piston 5 is provided to expel doses of this cosmetic product through a dispensing orifice 24, at the user's request.

[0037] The piston 5 moves in the body 2 along the X axis and is set in motion by means of a drive system actuated by manual rotation.

[0038] This drive system corresponds to wheel 3.

[0039] The piston 5 forms the bottom of the product storage chamber 10. Thus, when the user rotates the system, the piston 5 translates upwards, which has the effect of reducing the volume of the chamber 10 and causing an overpressure in the chamber 10, and a dose of product is expelled through the dispensing orifice 24.

[0040] More precisely, as can be seen in figures 2, 3 and 4, the body 2 has a hollow cylindrical shape.

[0041] The body is constituted by a peripheral wall 21, and is closed in the upper part by an upper wall 22 which is preferably integral with the peripheral wall 21 so as to form only one piece.

[0042] This upper wall 22 has the distribution orifice 24 at its central zone.

[0043] This upper wall 22 is slightly curved towards the inside of the body 2, so as to define a bowl 23 for retaining a dose of fluid product, which extends all around the dispensing orifice 24. This bowl shape 23 makes it possible to receive product without it overflowing from the upper wall 22. This also makes it easier for the user to recover his dose of product with his finger by scraping this bowl 23.

[0044] The peripheral wall 21 and the upper wall 22 of the body 2 partly form the chamber 10 for storing the cosmetic product.

[0045] The body 2 is not closed in the lower part. However, the piston 5 is arranged in the lower part of the body 2, and therefore acts as a bottom for the storage chamber 10.

[0046] The piston 5 is movable in translation inside the body 2, so as to vary the volume of the chamber 10.

[0047] The piston 5 has a circumferential lip 52 bearing in a sealed manner on an inner surface of the peripheral wall 21 of the body 2. This lip 52 provides a seal between the body 2 and the piston 5, so that there is no leakage of product under the piston 5.

[0048] In [Fig. 4], the piston 5 is located at the lower end of the body 2, so the volume of the chamber is at its maximum. Each time a dose of product is dispensed, the piston 5 rises slightly within the tube, so as to reduce the volume of the chamber 10. The piston 5 thus rises inside the body 2 until it comes to bear against the upper wall 22 of the body 2, which means that the chamber 10 is empty.

[0049] Preferably, the piston 5 has a central support 51 with a slightly domed shape, which matches the domed interior shape of the upper wall 22 of the body 2, so that it can come into abutment against this upper wall 22 with a flat contact, which means that all the product has been dispensed. This avoids having dead volumes with residual product once the piston 5 has reached the top stop within the body 2.

[0050] The piston 5 has a central well 53, extending axially from the support 51, inside which is inserted a threaded rod 33 coming from the wheel 3. The central well 53 is provided with an internal thread 54 capable of cooperating with the external thread 34 of the rod 33. Thus, when the user turns the wheel 3, the rod 33 also turns, and the piston 5 is driven axially in translation in the body 2 by means of the threads, in the manner of an endless screw.

[0051] The wheel 3 of the invention is mounted to be able to rotate in the body 2, so as to be able to rotate relative to the body 2.

[0052] This wheel 3 has a bottom wall 31 acting as a bottom for the pot 1. This wheel 3 also has an outer skirt 32 acting as a gripping area for the user. Indeed, the user holds the peripheral wall 21 of the body 2 in one hand, and turns the wheel 3 by gripping its outer skirt 32 with the other hand.

[0053] The threaded rod 33 extends from the bottom wall 31. This threaded rod 33 passes through the well 53 of the piston 5, then passes through the entire chamber 10 of the body 2, until it reaches the level of the distribution orifice 24.

[0054] A valve 6 for closing the distribution orifice 24 is mounted, from the outside of the body 2, on a free end 35 of the threaded rod 33.

[0055] Once mounted, the valve 6 is integral with the threaded rod 33, which means that it has no axial relative movement with respect to the threaded rod 33.

[0056] For example, the valve 6 can be mounted on the rod 33 by force, by fitting corresponding shapes. Any other fixing system can be envisaged within the framework of the present invention.

[0057] Advantageously, the free end 35 of the valve 6 is no longer threaded, and has a restricted diameter compared to the rest of the rod 33. For example, the free end 35 of the valve 6 may consist of a stud inserted inside a hole 62 provided for this purpose in the valve 6.

[0058] The valve 6 has a head 61 having a diameter slightly greater than the diameter of the distribution orifice 24, so as to be able to completely close the distribution orifice 24.

[0059] Advantageously, the upper wall 22 of the body 2 has a housing 11 for receiving the head 61 of the valve 6, so that the head of the valve 6 is flush with the upper surface of the upper wall 22, in the manner of a thread.

[0060] To avoid the phenomenon of remanence in the pot 1, that is to say to prevent product from coming out of the dispensing orifice 24 once the user has stopped rotating the wheel 3, it is provided that the valve 6 closes the dispensing orifice 24 as soon as the user finishes the actuation phase of the wheel 3.

[0061] In order for the valve 6 to be able to close the dispensing orifice 24, it must first be able to open it at the start of the actuation phase of the wheel 3.

[0062] Thus, it is necessary for the valve 6 to be able to move in translation along the X axis between a closed position, i.e. a low position where it is in abutment against the upper wall 22 of the body 2, and an open position, i.e. a high position at a distance from the upper wall 22 of the body 2.

[0063] In the closed position, the dispensing orifice 24 is closed.

[0064] In the open position, the dispensing orifice 24 is open.

[0065] Thus, the valve 6 can move back and forth over an axial stroke between its closed position and its open position.

[0066] In order for the valve 6 to be able to move back and forth, in a synchronized manner with the actuation phase, it is provided that the entire wheel 3 moves in translation relative to the body 2, therefore on the same axial stroke as the valve 6.

[0067] To carry out such a movement, the pot 1 comprises a cam system 25 and cam follower 36, which allows a rotational movement as well as a translational movement of the wheel 3 relative to the body 2 during the same actuation phase.

[0068] More precisely, the body 2 has a cam 25 consisting of a ramp 25, and the wheel 3 has a cam follower 36 consisting of at least one pin 36 arranged on ramp 25, and following the route of ramp 25.

[0069] Each pin 36 projects from an inner wall of the skirt 32 of the wheel 3.

[0070] In the example presented, the cam follower 36 is formed by four pins 36 distributed regularly on the skirt 32 of the wheel 3.

[0071] This ramp 25 is circumferential so as to allow the rotational movement of the wheel 3 relative to the body 2.

[0072] Furthermore, this ramp 25 is discontinuous, that is to say that it is composed of a succession of ramp sections 25a separated by returns 25b. Each return 25b corresponds to a notch. Thus, when the user turns the wheel 3 relative to the body 2, each pin 36 slides on a ramp section 25a, then slides on the adjacent return 25b, which informs the user that a notch has been passed. The passage of a notch informs the examiner that a dose of product has been dispensed.

[0073] In the example presented, each ramp section 25a corresponds to an angular sector equivalent to 45°.

[0074] With each rotary actuation of the wheel 3, the wheel 3 moves in translation relative to the body 2 from an initial position to a raised position as long as the pins 36 slide on the ramp sections 25a, then from the raised position to the initial position when the pins 36 slide on the returns 25b, marking the end of the dispensing of a dose of product.

[0075] In the example presented, the cam 25 consists of a groove made in the outer wall of the body 2. The pins 36 are thus axially locked inside this groove. Thus, the wheel 3 is axially locked relative to the body 2 when there is no rotational movement.

[0076] Each ramp section 25a corresponds to a helical section, with a low point 25c and a high point 25d. When the pin 36 is located at the low point 25c, at the start of the ramp section 25a, then the wheel 3 is in its initial position, and the valve 6 is in the closed position. When the pin 36 is located at the high point 25d, at the end of the ramp section 25a, then the wheel 3 is in its raised position, and the valve 6 is in the open position. The product can therefore be dispensed through the open orifice 24.

[0077] The return 25b corresponds to an axial section, the stroke of which corresponds to the axial distance between the low point 25c and the high point 25d of the helical ramp section 25a. Thus, at the end of the return 25b, the pin 36 is at the level of the low point 25c of the following ramp section 25a.

[0078] All the low points 25c have the same axial reference mark, and all the high points 25d have the same axial reference mark.

[0079] In this way, the wheel 3 translates relative to the body 2 in the same way on each section of ramp 25a, at each actuation. The wheel 3 thus performs successive back and forth movements relative to body 2 on the same axial stroke.

[0080] When the wheel 3 translates to its initial position, it drives the piston 5 with it on the same axial stroke. This means that the piston 5 descends inside the body 2, and increases the volume of the chamber 10. The increase in the volume of the chamber has the effect of suddenly reducing the pressure inside the chamber 10. Thus the product is no longer compressed against the dispensing orifice 24, and there is no remanence phenomenon.

[0081] With such a discontinuous ramp 25, the wheel 3 can only rotate relative to the body 2 in one direction of rotation. Indeed, it cannot rotate in the opposite direction because the pins 36 come into abutment against the returns 25b.

[0082] Preferably, the cam follower 36 is formed by two diametrically opposed pins 36, and each ramp section 25a corresponds to an angular sector equivalent to 45°.

[0083] Advantageously, the pot 1 comprises spring means forcing the wheel 3 to return to its initial position. In fact, the pins 36 can remain axially blocked at the level of the high point 25d of the ramp, corresponding to the start of the return 25b. Spring means are thus provided to drive the pins 36 on the return 25b and bring them back to the level of the low point 25c of the following ramp section 25a.

[0084] Preferably, these spring means consist of flexible blades 26, 26' provided on the body 2, and being in contact with the bottom wall 31 of the wheel 3, with a constraint during the mounting of the wheel 3 in the body 2.

[0085] These flexible blades 26, 26' are formed in a lower section 29 of the body 2, refined relative to the rest of the body 2 in order to gain flexibility.

[0086] In the first configuration, the lower section 29 of the body 2 is perforated by windows 27, below the ramp 25, so as to create ribs 26 connecting the non-perforated parts. These ribs 26, relatively thin, are thus very flexible, and form the flexible blades.

[0087] A tab 28 extends axially from the center of each rib 26. This tab 28 is designed to come into abutment against the bottom wall 31 of the wheel 3, and thus cause a deformation of the rib 26 so as to put it under stress during the assembly of the wheel 3 in the body 2.

[0088] When a pin 36 reaches the level of a return 25b, the stress exerted on the rib 26 causes a spring effect which brings the pin 36 back to the bottom of the return 25b, at the level of the low point 25c of the following ramp section 25a.

[0089] The friction exerted by the tabs 28 on the bottom wall 31 during rotation of the wheel 3 has the effect of slowing the rotation of the wheel 3 relative to the body 2 during actuation. The user thus has a better perception of the actuation, with better sensitivity when turning the wheel 3.

[0090] The pot 1 according to the invention is thus mainly made up of four parts, namely the body 2, the piston 5, the wheel 3, and the valve 6. This is a very reduced number of parts compared to the prior art.

[0091] Optionally, a cover 4 may be added. For example, the cover 4 may be mounted on the body 2 by a bayonet system 20, 44, as illustrated in Figures 3 and 4. The cover 4 could also be mounted on the body 2 by screwing.

[0092] Any system for removable mounting of the cover 4 relative to the body 2 can be envisaged within the framework of the present invention.

[0093] Advantageously, the cover 4 has means for bearing on the valve 6 forcing the valve 6 to remain in the closed position when the cover 4 is mounted on the body 2. In the illustrated case, these means of bearing consist of a protuberance 43 projecting from an upper wall 42 of the cover 4 in the direction of the valve 6, and coming to bear against the head 61 of the valve 6 when the cover 4 is mounted on the body 2.

[0094] Thus, the valve 6 can no longer open once the cover 4 is mounted on the body 2, even if the user tries to turn the wheel 3. The cover 4 thus makes it possible to lock the valve 6 in the closed position, which is practical for avoiding any accidental dispensing of product when transporting the pot 1.

[0095] Figures 5 and 6 show a second configuration of the pot 1 according to the invention.

[0096] All the description made previously for the first configuration of pot 1, for figures 3 and 4, remains valid for this second configuration of pot 1, except for the modifications below.

[0097] The flexible blades 26, 26' correspond this time to tabs 26' extending around the lower periphery of the body 2. These tabs 26' come into contact with the bottom wall 31 of the wheel 3, and deform to induce a stress between the wheel 3 and the body 2 when the two parts are mounted one inside the other, as explained previously.

[0098] The threaded rod 33 is this time hollow, whereas it was solid in the first configuration. The rod 33 has a free end 35 with an orifice for receiving a stud 63 of the valve 6. This stud 63 extends from the head 61 of the valve 6. The stud 63 of the valve 6 is snapped inside the orifice for receiving the threaded rod 33. There is therefore always an assembly with a form-fitting fit.

[0099] Preferably, the body 2, the wheel 3, the piston 5 and the valve 6 are made of the same plastic material. The lid 4 is also preferably made of the same plastic material. This avoids the user having to sort the different parts of his pot 1, according to the materials, to be able to throw it into different sorting bins.

[0100] The plastic material may be chosen from polypropylene (PP), polypropylene recycled (R-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, it is recycled or non-recycled polypropylene and / or polyethylene terephthalate.

[0101] Thus, advantageously, the body 2, the wheel 3, the piston 5, the valve 6 and the cover 4 are made of plastic material chosen from polypropylene and / or polyethylene terephthalate.

[0102] The use of plastic materials, in particular similar plastic materials for the entire pot 1, makes it easier to recycle. In particular, polypropylene and polyethylene terephthalate are two plastic materials whose recycling cycle is well known.

[0103] Pot 1 can be made using 3D printing.

[0104] In particular, the body 2, the wheel 3, the piston 5, the valve 6 and the cover 4 can be produced by 3D printing. Such a printing process makes it possible in particular to produce these parts very freely, presenting patterns and shapes contributing to the aesthetic appearance of the pot 1.

[0105] To use pot 1, the user must:

[0106] - turn the wheel 3 relative to the body 2 on an angular portion corresponding to a section of ramp of body 2, which simultaneously causes: • on the one hand a translation of the wheel 3 from an initial position to a raised position, which causes a translation of the valve 6 from a closed position to an open position, which causes the opening of the distribution orifice 24 by the movement of the valve 6 away from the body 2; • on the other hand a translation of the piston 5 within the body 2 in the direction of the valve 6, which causes a reduction in the volume of the chamber 10 with a compression, which causes an escape of a dose of product through the distribution orifice 24;

[0107] - continue to turn the wheel 3 relative to the body 2 until the detection of the passage of a notch following a ramp section 25a, which causes a translation of the wheel 3 from its raised position to its initial position, which causes a closing of the distribution orifice 24 by the valve 6, and which causes a translational movement of the piston 5 within the body 2 away from the valve 6, which causes an increase in the volume of the chamber 10 with decompression.

[0108] The configurations shown in the figures cited are only possible examples, in no way limiting, of the invention which on the contrary encompasses variants of shapes and of designs within the reach of the skilled person.

4. Pot (1) according to the preceding claim, characterized in that the ramp (25) is discontinuous, and formed by ramp sections (25a) connected by returns (25b) forming the notches, all the notches being located on the same axial reference of the X axis.

5. Pot (1) according to the preceding claim, characterized in that, with each rotary actuation of the wheel (3), the wheel (3) moves in translation relative to the body (2) from an initial position to a raised position as long as the pins (36) slide on the ramp sections (25a), then from the raised position to the initial position when the pins (36) slide on the returns (25b), marking the end of the dispensing of a dose of product.

6. Pot (1) according to one of claims 3 to 5, characterized in that the cam follower (36) is formed by two diametrically opposed pins (36).

7. Pot (1) according to one of the preceding claims, characterized in that an actuation of the wheel (3) corresponds to a rotation over an angular sector of 45°.

8. Pot (1) according to one of the preceding claims, characterized in that the movement of the wheel (3) in translation from its initial position to its raised position, and vice versa, causes the movement of the valve (6) in translation from its closed position to its open position, and vice versa.

9. Pot (1) according to one of the preceding claims, characterized in that it also comprises a cover (4) for closing the pot (1), having means for pressing on the valve (6) forcing the valve (6) to remain in the closed position when the cover (4) is mounted on the body (2).

10. Pot (1) according to one of the preceding claims, characterized in that it is made of a single material.

11. Pot (1) according to one of the preceding claims, characterized in that it comprises spring means between the body (2) and the wheel (3), forcing the wheel (3) to return to its initial position after each actuation.

12. A method of dispensing a cosmetic product from a jar (1) according to claim 1, when dependent on claim 4, comprising the following steps: turn the wheel (3) relative to the body (2) on a portion angular corresponding to a section of ramp (25a) of the body (2), which simultaneously causes: • on the one hand a translation of the wheel (3) from an initial position to a raised position, which causes a translation of the valve (6) from a closed position to an open position, which causes the opening of the distribution orifice (24) by moving the valve (6) away from the body (2); • on the other hand a translation of the piston (5) within the body (2) in the direction of the valve (6), which causes a reduction in the volume of the chamber (10) with a compression, which causes an escape of a dose of product through the dispensing orifice (24); continue to turn the wheel (3) relative to the body (2) until the detection of the passage of a notch following a ramp section (25a), which causes a translation of the wheel (3) from its raised position to its initial position, which causes a closing of the distribution orifice (24) by the valve (6), and which causes a translational movement of the piston (5) within the body (2) away from the valve (6), which causes an increase in the volume of the chamber (10) with decompression.
