Dispensing head with integrated tank for storage container

The present invention relates to a dispensing head capable of being mounted on a container for storing a first product, this product being intended to be mixed before use with a second product contained inside the same head.

The invention is particularly suitable for the packaging of cosmetic, pharmaceutical or dermatopharmaceutical products. Such products can for example be distributed in aqueous form, an oil, a milk, a cream, a gel, a foam, a powder, an emulsion, etc.

In the field of cosmetics, the product compositions are generally prepared by the manufacturer according to the needs common to a plurality of users.

However, in this area, there is today a tendency which consists in personalizing the cosmetic formulas according to the needs specific to each user. In particular, before application, it is possible to mix with the cosmetic formulation prepared by the manufacturer additives packaged in solid form, such as tablets, capsules, powder or crushed, granules, etc.

Furthermore, regardless of this trend, certain cosmetic products can only be brought into contact with each other at the time of application for reasons of stability.

To meet these different needs, the applicant has developed a dispensing head for a storage container which makes it possible to separately deliver a first cosmetic product stored in this container and a second separate cosmetic product contained inside a tank of the head. . For more detail, reference may be made to patent application FR-A1-2 981 555.

So as to provide for a selective distribution of the first product from the container independently of the second product stored inside the dispensing head, the latter is equipped with a metering mechanism interposed between the reservoir dedicated to this second product and the associated dispensing orifice.

The metering mechanism comprises a shutter which is mounted movable in translation between a position for closing the dispensing orifice of the second product and a dispensing position. The shutter can be actuated from the outside by the user via an actuation button which extends beyond the reservoir of the dispensing head. The shutter is equipped with an elastic return member so as to automatically obtain a return to the shutter position when the user releases the actuation button.

The dispensing head described in this patent application thus has the advantage of allowing the user to mix the first and second products stored separately, just before application.

Separating the two types of products in separate tanks also has manufacturing advantages. Indeed, if the second product is in the form of abrasive particles, for example exfoliating particles, and is mixed with the first product by the manufacturer during the preparation of the cosmetic formulation, these particles tend to abrade the manufacturing tank of this formula and the pipes connected to this tank which fill the packaging containers.

However, the dispensing head described in this patent application comprises a shutter of complex shape and requiring continuous pressure on the associated actuation button in order to obtain the distribution of the second product.

The present invention aims to remedy these drawbacks.

More particularly, the present invention aims to provide a dispensing head capable of being mounted on a container for storing a first product and making it possible to deliver this first product separately and at least to the second separate product, in a simplified manner.

The present invention also aims to provide a head of simple, economical design and making it possible to obtain a distribution of the products according to a gesture of use different from conventional distribution heads.

The subject of the invention is a dispensing head for a container intended to contain a first product, in particular a cosmetic product. The head comprises a mounting base intended to be fixed on the container and internally delimiting at least one reservoir intended to contain a second product, in particular a cosmetic product. The head also includes a first product supply conduit extending at least partially inside said tank, a first product distribution orifice in communication with the first product supply conduit, and at least a second distribution orifice fitted on the mounting base and in communication with the reservoir of the second product. The head also comprises a shutter member movable at least between a shutter position and an open position of said second dispensing orifice.

According to a general characteristic of the invention, the shutter member is mounted on the mounting base while being movable in rotation relative to said base to cover, on the side external to said reservoir of the second product, said second dispensing orifice. in the closed position and to leave at least partially cleared said second orifice in the open position.

According to another general characteristic of the invention, said second dispensing orifice is in permanent communication with the reservoir of the second product in the closed and open positions of the closed member.

By “dispensing orifice in permanent communication with the reservoir”, it is meant that said orifice remains open on the side of the reservoir regardless of the position of the closure member relative to the mounting base. The shutter member does not allow the communication between the reservoir and said second dispensing orifice to be interrupted. The obturator part of the obturator capable of covering said second orifice is mounted outside of this tank.

Achieving the sealing function of the second product orifice (s) on the outside of the reservoir of the mounting base makes it possible to simplify the design of the dispensing head. The number of parts to be manufactured and assembled is also reduced.

In addition, taking into account the rotary assembly of the obturation member, the use of the head is significantly different from that of conventional dispensing heads.

Preferably, the shutter member is movable in rotation about a longitudinal axis of the mounting base. This promotes good ergonomics of use when the shutter is actuated. Advantageously, the axis of the first product dispensing orifice can be coaxial or parallel to this longitudinal axis.

According to an advantageous design of the dispensing head, the shutter member is provided with the first dispensing orifice. In this case, the obturation member fulfills a double function, namely closing or leaving free said second orifice, and ensuring distribution of the first cosmetic product via the first orifice.

With such a design, it is also possible to provide for the first dispensing orifice to be arranged on a front wall of the shutter member. This facilitates the collection of the first product during its distribution.

According to another design of the dispensing head, it might be possible to provide that the supply duct delimits the first dispensing orifice.

In an advantageous embodiment, the shutter member comprises a through opening to leave said second distribution orifice at least partially cleared in the open position of said member. Preferably, this opening is shaped so as to leave completely free the second distribution orifice (s) in the open position of the shutter member.

Furthermore, it is also possible to equip the shutter member with abutment elements cooperating with complementary abutment elements of the mounting base to limit the rotation movement of said shutter member between the position of shutter and open position. The provision of such abutment elements facilitates rapid passage from the shutter position to the open position, and vice versa. By way of example, these abutment elements can be formed by two diametrically opposite lugs formed on the shutter member and coming to engage inside two grooves formed on the mounting base.

In a particular design of the dispensing head, the mounting base comprises a side skirt on which said second product dispensing orifice is arranged.

When the first distribution orifice is oriented substantially coaxially or parallel to the longitudinal axis of the mounting base, such an arrangement of the second distribution orifice (s) on the side skirt of this base is particularly advantageous. In fact, this greatly reduces the risk of the first orifice being blocked by the second product delivered through the second or orifices, and vice versa.

Alternatively, it remains however possible to arrange said second orifice on a front wall of the base.

In a particular embodiment, the mounting base can comprise the supply duct for the first product. Alternatively, the obturation member may include the supply duct.

Preferably, the dispensing head further comprises a movable closure cover between a closed position of the first dispensing orifice and a position of opening of said first orifice, said closure cover covering the shutter member in the position of closing. The hood is a separate part of the shutter. This cover can be movable in rotation about an axis of articulation transverse to a longitudinal axis of the mounting base. Alternatively, the cover can be removable, for example screwed.

In a first design of the head, the closure cover can be rotatably mounted on the shutter member. In a second design, the cover can be rotatably mounted on the mounting base.

In an advantageous embodiment, the closing cover can advantageously be configured so that it can pass from the opening position to the closed position only when the shutter member is in the shutter position. This ensures a watertight closure of the second distribution orifice (s) by the shutter member. Such a design can be envisaged when the cover is rotatably mounted on the mounting base but also when the cover is rotatably mounted on the shutter member.

The invention also relates to a device for packaging and distributing products, in particular cosmetic products, comprising a container delimiting a first reservoir for storing a first product and a dispensing head as defined above. The supply duct of the distribution head is in communication with the first reservoir and said reservoir of the base of this head forms a second reservoir containing a second product.

Advantageously, the device can be used for packaging cosmetic, pharmaceutical or dermato-pharmaceutical products. The first product stored in the container can for example be in a fluid or viscous form while the second product can be in a solid form.

In a cosmetic application, the first product can for example be an oil, a milk, a cream, a gel, a foam, a powder, an emulsion, a wax, a paste, etc. The first product may for example be a care product, such as a face or body cream formula, a shampoo, a hair mask, a makeup-removing oil, a treating cream, a washing cream, a scrub, a mask, sunscreen. The second product may contain active ingredients, pigments, proteins, salts, gelling powders, exfoliating particles, nacres, or other compounds generally used in cosmetic compositions. The second product can for example be in the form of powder, tablets, particles, capsules or beads.

FIG. 10 is an exploded perspective view of a product packaging device equipped with a dispensing head according to a third embodiment of the invention, and

- Figures 11 and 12 are perspective views of a product packaging device equipped with a dispensing head according to a fourth embodiment of the invention respectively in a dispensing position of a first product and in a distribution position of a second product.

In Figures 1 and 2 is shown a product packaging device, designated by the general reference 10, which comprises a storage container 12 and a dispensing head 14. The device 10 is shown in a position with the dispensing head 14 disposed below the container 12.

The container 12 is intended to store a first cosmetic product, advantageously in fluid or viscous form, while the dispensing head 14 is designed to store a second cosmetic product, advantageously in solid form. In the figures, the cosmetic products are not shown.

As will be described in more detail below, the dispensing head 14 makes it possible to selectively dispense the first and second cosmetic products.

The container 12 extends along a longitudinal geometric axis X-X ’. The container 12 internally delimits an internal volume forming a first reservoir 16 (FIG. 3) filled with the first cosmetic product. The container 12 has one end forming a bottom and an opposite open end forming a neck 18. The neck 18 is separated from the periphery of the container by an annular shoulder. The dispensing head 14 is mounted on the neck 18. For this purpose, the neck 18 is provided externally with a snap hook 20 on which the dispensing head 14 is hung. Alternatively, the head 14 can be fixed to the container 12 by any other suitable attachment element, for example by screwing, by tight adjustment, etc.

In the illustrated embodiment, the container 12 is in the form of a tube with a deformable wall. As a variant, the container 12 can be in the form of a bottle equipped with a product distributor, such as a pump without return air or a valve of the aerosol valve type.

The dispensing head 14, coaxial with the axis XX ′, comprises a hoop or base 22 for mounting on the container 12 which internally delimits a second compartment or reservoir 24 filled with the second cosmetic product, a sealing member 26 mounted movable in rotation on the base around said axis XX ′ to allow or not a distribution of this second product, and a cover 28 for closing.

As illustrated more clearly in FIG. 3, the mounting base 22, of axis X-X ′, comprises an inner skirt 30 for annular attachment fitted internally with a hook (not referenced) snapped onto the hook 20 of the container to secure the attachment of the head 14 to this container. The hook of the skirt 30 can be continuous or discontinuous in the circumferential direction.

The mounting base 22 also includes an interior supply duct 32 in communication with the reservoir 16 of the container 12, and an annular outer skirt 34 for mounting the shutter member 26. The mounting skirt 34 surrounds radially the attachment skirt 30 and the supply conduit 32. The skirt 34 extends in the extension of the periphery of the container 12. The skirts 30, 34 are centered on the axis XX ′ and extend axially on the side opposite to the container 12. In the illustrated embodiment, the skirts 30, 34 each have a circular cross section. Alternatively, it might be possible to provide at least for the skirt 34 a polygonal section, in particular a square section, or even an oval section.

The skirt 30 for attaching the base is extended, at a first axial end, by a radial front portion 36 from which the supply duct 32 extends axially. At a second opposite axial end, the skirt 30 is extended by a bottom wall 38 abutting against the shoulder of the container 12 so as to ensure the axial positioning of the dispensing head 14.

ίο

In the exemplary embodiment illustrated, the base 22 also comprises an annular sealing lip 40 which is centered inside the neck 18 of the container. The free end of the neck 18 is located radially between the attachment skirt 30 and the lip 40. The lip 40 is centered on the axis X-X ’. The lip 40 extends from the front portion 36 axially on the side opposite to the supply duct 32.

The supply duct 32, of axis XX ′, internally delimits a distribution channel 42 which is in communication with the reservoir 16 of the container containing the first cosmetic product and separated in a sealed manner from the reservoir 24 of the base containing the second cosmetic product. The channel 42 is here in fluid communication with the reservoir 16 by means of the lip 40 which engages inside the neck 18 of the container. As a variant, the channel 42 of the supply duct could open directly inside the container 12. As will be described in more detail below, the channel 42 of the supply duct 32 is also in communication with a first orifice 44 of distribution arranged on the shutter member 26.

Regarding the reservoir 24 of the base, this is here defined radially on the inner side by the supply duct 32 and the hooking skirt 30, and radially on the outer side by the mounting skirt 34. The reservoir 24 extends partly around the supply duct 32. The reservoir 24 is axially delimited by the bottom wall 38 on the side of the container 12. The reservoir 24 is open axially on the opposite side, and is closed by the shutter 26.

Referring again to FIG. 2, the mounting base 22 comprises a plurality of second distribution orifices 46 formed through the thickness of the side skirt 34 of the base. The orifices 46 open radially from the inner side into the reservoir 24 and from the outer side onto the outer surface of the skirt 34. The orifices 46 are through. The orifices 46 extend radially. The orifices 46 are arranged near the end of the skirt 34 located on the side of the closure member 26.

The holes 46 are four in number here. Alternatively, it is possible to provide a different number of orifices, for example one, two, three, five etc. In the exemplary embodiment, the base 22 is made in one piece, preferably by molding a thermoplastic material.

The closure member 26 closes the reservoir 24 to allow distribution of the second cosmetic product contained by the latter exclusively through the orifices 46. The closure member 26 comprises a partition or front wall 48 of end on which is formed the first dispensing orifice 44, and an annular lateral peripheral skirt 50 extending said wall on the side of the base 22. The skirt 50 axially extends a large diameter edge of the front wall 48. The front wall 48 is under the shape of a disc. The skirt 50 radially surrounds the skirt 34 of the mounting base. The skirt 50 is engaged around the mounting base 22 so as to cover the distribution orifices 46 on the side outside the reservoir 24. The orifices 46 are in permanent communication with the reservoir 24. The skirt 50 forms on the member d obturation 26 the obturating part making it possible to cover and thus to close the orifices 46.

As illustrated in FIG. 3, the skirt 50 of the shutter member is internally provided with a snap hook 52 which extends inside a groove (not referenced) formed on the skirt 34 of the mounting base. Thus, the axial retention of the shutter member 26 on the mounting base 22 is obtained.

The shutter member 26 is mounted movable in rotation relative to the base 22 around the axis XX ′ between a position for closing the orifices 46 and an open position in which it is possible to obtain a distribution of the second product contained in the reservoir 24 through these orifices. The shutter member 26 is axially integral with the mounting base 22 while being movable in rotation about the axis X-X ’relative to the latter.

So as to limit the rotation movement of the shutter member 26, the latter further comprises two lugs 54, 56 formed in the bore of the skirt 50 and each engaging inside a groove 58 , 60 formed on the skirt 34 of the mounting base. The lugs 54, 56 are diametrically opposite and identical. Each lug 54, 56 extends radially inward. The grooves 58, 60 are also diametrically opposite and identical.

The shutter member 26 further comprises an annular centering skirt 62 extending from the front wall 48 and coming to engage in leaktight manner inside the supply duct 32 of the mounting base. The skirt 62 internally delimits a channel 64 which is in communication with the channel 42 of the supply duct on one side, and which opens at the level of the orifice 44 of distribution on the other side. The orifice 44 is in fluid communication with the channel 42 of the supply conduit 32. The orifice 44 of distribution is formed through the thickness of the front wall 48 of the obturation member. Port 44 extends axially. Port 44 is centered on the X-X axis.

In order to further promote the watertight separation of the reservoir 24 and the supply duct 32, the closure member 26 comprises an annular sealing skirt 66 which extends from the front wall 48 and which rubs radially against said supply conduit. The supply duct 32 is mounted radially on the inside against the skirt 62 and radially on the outside against the skirt 66.

Referring again to Figure 2, the shutter member 26 includes a through opening 68 formed through the thickness of the mounting skirt 50. The opening 68 extends radially through this thickness. In the example embodiment illustrated, the opening 68 is in the form of a slot. As will be described in more detail below, the opening 68 of the obturating member allows distribution to the outside of the second product contained in the reservoir 24 through the orifices 46.

The closing cover 28 is articulated in rotation on the shutter member 26 by means of a hinge 70 with a Y-Y hinge axis "transverse to the X-X" axis. The closing cover 28 is movable between a position for closing the first orifice 44 and a position for opening said orifice. In the closed position, the cover 28 covers the shutter member 26. The cover 28 has a generally cylindrical shape and is provided with a closing pad 72. In this closed position, the stud 72 engages inside the channel 64 of the shutter member to close it tightly and prevent product from escaping through the orifice 44.

To obtain the distribution of the products which are contained and separated in leaktight manner in the device 10, the user can proceed as follows.

When the user wishes to use only the first cosmetic product contained in the container 12, he passes the cover 28 from the closed position illustrated in FIG. 1 to the open position illustrated in FIG. 4 in which the orifice 44 distribution is completely clear.

The distribution of the first cosmetic product through this orifice 44 can then be obtained, here by pressing on the deformable wall of the container 12. The first cosmetic product can for example be collected on the surface to be treated, for example on keratin fibers or the skin of the user, or on a suitable applicator.

During the distribution of the first cosmetic product contained in the reservoir 16 of the container, the product passes through the supply duct 32 of the mounting base, then of the skirt 62 of the closure member before being distributed through the orifice 44. The circulation of the first cosmetic product from the container 12 to the orifice 44 takes place in a completely sealed manner with respect to the reservoir 24 of the mounting base containing the second cosmetic product.

During this distribution of the first cosmetic product, the shutter member 26 is in its shutter position and covers the orifices 46 of the mounting base on the outside. These orifices 46 are closed by a solid region of the skirt 50 of the shutter member disposed radially opposite. Distribution to the outside of the second product contained in the reservoir 24 is prevented in the closed position of the closed member 26.

When the user wishes to add a second cosmetic product to the first product which has just been dispensed, he rotates the closure member 26 around the axis XX ′ to cause it to pass towards its open position as shown in Figure 5.

In this position, the opening 68 of the shutter member leaves the orifices 46 entirely clear. The opening 68 is disposed radially opposite the orifices 46. A dose of second product can then be extracted by gravity from the reservoir 24 of the dispensing head and pass through the orifices 46 and the opening 68. The distribution of the second product is facilitated when the dispensing head 14 is oriented downwards.

The rotational movement of the shutter member 26 relative to the base 22 from the shutter position to the open position, and vice versa, is limited by the contact in the circumferential direction between the pins 54, 56 and the lateral edges of the grooves 58, 60 (Figures 2 and 3). The circumferential dimensioning of these grooves 58, 60 is adapted so that, in the closed position in which the orifices 46 are covered, each lug 54, 56 abuts against one of the lateral edges of the associated groove and that, in the open position in which the orifices 46 are left free, each lug 54, 56 abuts against the opposite lateral edge of said groove.

In the example of use of the device 10 which has just been described, the distribution of the second product through orifices 46 is carried out while the cover 28 has remained in the open position. Alternatively, as illustrated in FIG. 6, it is also possible to distribute this second product when the cover 28 is in the closed position taking into account the arrangement of the orifices 46 which are formed on the peripheral skirt 34 of the 'base.

The embodiment illustrated in FIG. 7, on which the identical elements bear the same references, differs mainly from the previous example in that the mounting base 22 of the dispensing head of the device also comprises a plate 80 which is attached and fixed to the peripheral skirt 34, by any suitable element, for example by snap-fastening, screwing, gluing, etc. The plate 80 includes a central recess 82 to allow the passage of the supply conduit 32. The supply conduit 32 extends in a sealed manner through the recess 82. In this embodiment, the base 22 of mounting is obtained by assembling two separate parts.

The tray 80 of the base closes the reservoir 24 to allow distribution of the second cosmetic product contained by the latter exclusively through distribution holes 84 provided on this tray. The holes 84 extend through the thickness of the plate 80. The through holes 84 extend axially. The orifices 84 open axially from the inner side into the reservoir 24 and from the outer side onto a front surface of the plate which is covered from the outside by the shutter member 26. The front wall 48 of the shutter member covers the orifices 84 on the side outside the reservoir 24. The orifices 84 are in permanent communication with the reservoir 24. The front wall 48 of the obturation member 26 forms the obturating part enabling the orifices 84 to be covered.

So as to allow distribution to the outside of the second product contained in the reservoir 24, the shutter member 26 here comprises a through opening 86 formed through the thickness of the front wall 48. The opening 86 is extends axially across this thickness.

To obtain product distribution, the user can proceed in a similar manner to the first embodiment described. When the user wishes to dispense only the first cosmetic product contained in the container 12, he passes the cover 28 into its open position illustrated in FIG. 8 in order to then be able to obtain a product outlet through the orifice 44. During this distribution of the first cosmetic product, the shutter member 26 is in its shutter position and covers the orifices 84 of the mounting base (FIG. 7). These orifices 84 are closed by a solid region of the front wall 48 of the shutter member disposed axially opposite.

Then, if the user wishes to add a second cosmetic product, he rotates the shutter member 26 around the axis XX ′ to move it from its shutter position to its open position illustrated in FIG. 9. In this position, the opening 86 of the shutter member leaves these orifices 84 entirely free. The opening 86 is disposed axially opposite the orifices 84. The orifices 84 are offset laterally outwards relative to port 44.

Given the arrangement of the orifices 84, the distribution of the second cosmetic product is also obtained on the front side of the dispensing head 14 as is also the case for the first cosmetic product. It will be appreciated that in this example, it is not possible, unlike the first embodiment described, to obtain a distribution of the second cosmetic product in the closed position of the cover 28.

In the embodiments which have just been described, the opening 68 or 86 of the shutter member is associated with the plurality of orifices 46, 84 to obtain the distribution of the second cosmetic product. As a variant, it is possible to provide an inverted arrangement with a single opening made on the mounting base and a plurality of holes provided on the shutter member. In this case, the opening of the base forms the dispensing orifice of the second cosmetic product in permanent communication with the reservoir 24.

The embodiment illustrated in FIG. 10, in which the identical elements bear the same references, differs in particular from the preceding example in that the second orifice for dispensing the product is formed by the free end of the peripheral skirt 34 of the base. The mounting base 22 comprises a front wall 88 extending over a limited angular sector and extending radially inwards from the bore of the skirt 34 in the direction of the supply conduit 32. This front wall 88 came integrally with the skirt 34. The mounting base 22 also comprises two axial walls 90 (only one being visible in the figure) each extending axially from one of the lateral edges of the front wall 88 of the side of the bottom wall of the base and also connecting to the bore of the skirt 34. The front wall 88 and the axial walls 90 define an empty chamber oriented axially on the side of the container 12. In this example, the reservoir 24 therefore does not extend over 360 °.

In this exemplary embodiment, the shutter member 26 includes a through opening 92 formed through the thickness of the front wall 48 and being in the form of a slot. The opening 92 extends axially through this thickness.

In the closed position, the opening 92 is disposed axially opposite the front wall 88 so as to prevent distribution of the second product contained in the reservoir 24. For this purpose, the front wall 88 is equipped with a lug 94 projecting so as to come as close as possible to the opening 92 in the closed position. The front wall 48 forms on the obturation member 26 the obturating part which is able to cover the dispensing orifice formed by the free end of the peripheral skirt 34 of the base.

To obtain a distribution of the product contained in the reservoir 24, it suffices to move the closure member 26 in rotation around the axis X-X ’so that the opening 92 comes axially opposite the reservoir 24.

In the exemplary embodiments which have just been described, the shutter member 26 and the closing cover 28 are made in one piece, i.e. in one piece, by molding a thermoplastic material.

As a variant, it is possible to produce the shutter member 26 and the cover 28 in the form of two separate parts and to provide an attached hinge pin to ensure the rotational mounting of the cover 28 around the Y axis. -Y. Alternatively, it could also be possible to provide a mounting of the cover 28 on the shutter member 26 by snap-fastening. However, with this alternative solution, there is a risk of loss of the cover 28 by the user when the latter has been removed so as to gain access to the dispensing orifice 44.

The embodiment illustrated in Figures 11 and 12, in which the identical elements bear the same references, differs mainly from the second embodiment by the design of the shutter member 100 of the dispensing head.

In this embodiment, the shutter member 100 comprises a front end wall 102 partially covering the front wall of the base formed by the plate 80, two lateral branches 104, 106 each extending the end wall axially 102 and extending outside the skirt 34 of the base, and an annular belt 108 surrounding said skirt and connecting the free ends of these branches. Analogously to the embodiments described above, the shutter member 100 is axially integral with the mounting base 22 while being movable in rotation about the axis X-X 'relative to the latter. The shutter member 100 is here made in one piece, preferably by molding a thermoplastic material.

The shutter member 100 comprises an orifice 110 formed through the thickness of the end wall 102 which is in fluid communication with the supply duct 32. The orifice 110 extends axially. Port 110 is centered on the X-X axis. The end wall 102 of the closure member is in the form of a strip. The width of this end wall 102 is adapted so as to be able to completely cover the orifices 84 of the base on the side outside the reservoir 24 in the closed position as illustrated in FIG. 11. The wall of end 102 of the shutter member 26 forms the shutter part capable of covering the orifices 84. In this embodiment, the orifices 84 are arranged in two rows. It is of course possible to provide a different arrangement and number of orifices. To obtain the passage of the shutter member 100 towards the open position, the latter is rotated around the axis XX ′ so as to uncover the orifices 84 as illustrated in FIG. 12 .

In this exemplary embodiment, the cover 28 is mounted for rotation on the mounting base 22, and more precisely on the peripheral skirt 34, by the hinge 70. The cover 28 comprises two notches 112, 114 arranged and shaped so as to allow the latter to pass from its open position to the closed position only when the shutter member 100 covers the orifices 84.

Analogously to the embodiments previously described, abutment elements may be provided on the skirt 34 of the mounting base and on the closure member, for example on the branches 104, 106 or even on the belt 108 , to limit the rotational movement of the shutter member between the shutter position and the open position of the orifices 84.

In the illustrated exemplary embodiments, the base 22 for mounting the dispensing head delimits a single reservoir 24. As a variant, it is possible to provide a design in which the base delimits a plurality of reservoirs intended to contain each of the products different. With such a design, at least one dispensing orifice is associated with each reservoir and the shutter member is common to these different orifices.

Thanks to the invention, there is a dispensing head comprising at least one internal reservoir for storing a product and making it possible to authorize a selective distribution of this product or of the product contained inside the container on which the head is mounted, and this, by simple rotation of the shutter member. In addition, the fact that the obturation member covers on the outside the distribution orifice (s) in communication with the internal reservoir makes it possible to obtain a head of simple and economical design.
