Avantageusement, la tete de distribution comporte un profil de pulverisation 21, de preference realise dans la paroi frontale de fond 20 du canal d'expulsion 2, ltorifice de distribution 3 se trouvant alors au centre audit profil de pulverisation 21. De preference, et de maniere connue, le profil de pulverisation peut comprendre des canaux de tourbillonnement qui se connectent a une chambre de  Advantageously, the dispensing head comprises a spraying profile 21, preferably made in the front end wall 20 of the expulsion channel 2, the dispensing orifice 3 then being in the center of said spraying profile 21. Preferably, and in known manner, the spray profile may include swirl channels which connect to a

Selon ['invention, I'insert rigide 4 est dispose de maniere mobile dans le canal d'expulsion 2, entre une position de repos representee sur la figure 1 et une position d'actionnement representee sur la figure 2. Un element d'obturation 10 est en outre dispose dans le canal d'expulsion 2, et coopere d'une part avec le corps 1 de la tete de distribution et d'autre part avec ['insert rigide 4 de telle sorte qu'en position de repos de ['insert rigide 4, ['element d'obturation 10 obture de maniere etanche ltorifice de distribution 3. En position d'actionnement de ['insert rigide 4, ltelement d'obturation 10 est deplace et/ou deforme vers une position de non-obturation, dans laquelle il libere le passage pour le produit en  According to the invention, the rigid insert 4 is movably disposed in the expulsion channel 2, between a rest position shown in Figure 1 and an actuation position shown in Figure 2. A shutter element 10 is further arranged in the expulsion channel 2, and cooperates on the one hand with the body 1 of the dispensing head and on the other hand with ['rigid insert 4 so that in the rest position of [ 'rigid insert 4, [' shutter element 10 seals the dispensing orifice 3. In the actuating position of ['rigid insert 4, the shutter element 10 is moved and / or deformed to a non- obturation, in which it frees the passage for the product in

s direction de ['orifice de distribution 3.  s direction of the dispensing orifice 3.

En reference aux figures 1 et 2, qui montrent un premier mode de realisation avantageux de ['invention, ['element d'obturation 10 comporte un manchon creux 11 qui est dispose autour d'une extremite aval 5 de ['insert rigide 4. Le manchon est assemble dans le canal d'expulsion 2 et coopere d'une part o avec la paroi frontale 20 du canal d'expulsion 2 et d'autre part avec moyen de retenue 25, tel qu'un epaulement ou une proJection, prevu dans la paroi laterale du canal d'expulsion 2. L'element d'obturation 10 comporte en outre une paroi d'extremite radiale recouvrant ladite extremite aval 5 de ['insert rigide 4, et comportant une partie d'obturation 15. Dans l'exemple represente, la partie is d'obturation 15 est avantageusement realisee sous la forme d'une paroi ou membrane elastiquement deformable. Comme represente sur les figures 1 et 2, en position de repos de ['insert rigide 4, la partie d'obturation 15 est deforme axialement par une force de compression axiale exercee sur elle par ['insert rigide 4, de telle sorte qu'elle coopere de maniere etanche avec ['orifice de distribution 3, comme represente sur la figurrl. Au moment de ['expulsion du produit, ['insert rigide 4 est deplace vers sa position d'actionnement en coulissant dans ledit manchon creux 11 qui reste fixe. L'insert 4 ntexerce plus alors cette force de compression axiale sur la paroi d'extremite radiale 12 de ['element d'obturation , qui revient elastiquement vers sa position d'ouverture, representee sur la figure 2, dans laquelle elle est decollee de ['orifice de distribution 3, liberant ainsi  With reference to FIGS. 1 and 2, which show a first advantageous embodiment of the invention, the closure element 10 comprises a hollow sleeve 11 which is arranged around a downstream end 5 of the rigid insert 4. The sleeve is assembled in the expulsion channel 2 and cooperates on the one hand with the front wall 20 of the expulsion channel 2 and on the other hand with retaining means 25, such as a shoulder or a projection, provided in the side wall of the expulsion channel 2. The closure element 10 further comprises a radial end wall covering said downstream end 5 of the rigid insert 4, and comprising a closure part 15. In the The example shown is the obturation part 15 which is advantageously produced in the form of an elastically deformable wall or membrane. As shown in FIGS. 1 and 2, in the rest position of the rigid insert 4, the closure part 15 is deformed axially by an axial compressive force exerted on it by the rigid insert 4, so that it cooperates in a sealed manner with the dispensing orifice 3, as shown in FIG. When the product is expelled, the rigid insert 4 is moved to its actuating position by sliding in said hollow sleeve 11 which remains fixed. The insert 4 then no longer exerts this axial compressive force on the radial end wall 12 of the shutter element, which returns elastically to its open position, represented in FIG. 2, in which it is detached from ['dispensing orifice 3, thereby freeing

le passage dans le canal d'expulsion 2.  passage through the expulsion channel 2.

Avantageusement, comme decrit precedemment, la paroi frontale 20 du canal d'expulsion 2 peut comporter un profil de pulverisation 21. Le mode de realisation representee sur les figures presente dans ce cas un avantage o important, en ce quten position d'actionnement ou de distribution, le profil de pulverisation 21 presente une geometric non modifiee, puisque le manchon creux 11 reste fixe, ledit manchon 11 formant les parois de fond des canaux de pulverisation. Ceci est different des obturateurs existants a ce jour, realises en materiau deformable, qui vent generalement deformes elastiquement vers leur position de non-obturation, de sorte que le profil de pulverisation est s necessairement modifie au moment de ['expulsion, ce qui peut alterer la qualite du spray. Cet inconvenient ntest pas reproduit par la presente invention, comme  Advantageously, as described above, the front wall 20 of the expulsion channel 2 may include a spray profile 21. The embodiment shown in the figures in this case presents an advantage o significant, in that actuation position or distribution, the spray profile 21 has an unmodified geometric, since the hollow sleeve 11 remains fixed, said sleeve 11 forming the bottom walls of the spray channels. This is different from the shutters existing to date, made of deformable material, which generally wind elastically deformed towards their non-shutting position, so that the spraying profile is necessarily changed at the time of expulsion, which can alter the quality of the spray. This drawback is not reproduced by the present invention, as

clairement visible sur les figures 1 et 2.  clearly visible in Figures 1 and 2.

La figure 3 montre un second mode de realisation, dans lequel le manchon creux 11 n'est pas fixe dans le canal 2, mais fixe sur l'extremite aval 5 o de ['insert rigide 4. L'element d'obturation 10 se deplace done entierement avec ['insert 4. La partie d'obturation 1S est avantageusement realisee sous la forme d'un plot ou ergot qui est comprime contre ltorifice de distribution 3 en position d'obturation, et qui est decolle audit orifice de distribution 3 en position de  FIG. 3 shows a second embodiment, in which the hollow sleeve 11 is not fixed in the channel 2, but fixed on the downstream end 5 o of the rigid insert 4. The obturation element 10 is therefore moved entirely with the insert 4. The closing part 1S is advantageously produced in the form of a stud or lug which is compressed against the distribution orifice 3 in the closed position, and which is detached from said distribution orifice 3 in position of

is Au moins la partie d'obturation 1S de ltelement d'obturation 10 est realisee en un materiau deformable, tel qu'un materiau elastomere. Pour simplifier la fabrication, on peut realiser ['element d'obturation 10 entierement de maniere monobloc en un materiau deformable. Ceci stapplique bien entendu  is At least the closure portion 1S of the closure element 10 is made of a deformable material, such as an elastomeric material. To simplify the manufacture, the closure element 10 can be made entirely in one piece in a deformable material. This of course applies

aux deux modes de realisation decrits ci-dessus.  to the two embodiments described above.

La figure 4 represente un exemple de realisation avantageux d'un distributeur comportant, a titre d'exemple, une tete de distribution telle que decrite ci-dessus en reference aux figures 1 et 2. n comporte un reservoir (non represente) contenant le produit s distribue, sur lequel est monte un organe de distribution, telle qu'une pompe SO, qui comporte un piston 51, coulissant dans un corps de pompe, l'actionnement audit piston S 1 permettant de distribuer selectivement le produit contenu dans le reservoir. Une chambre de pompe 52 est definie entre un clapet d'entree 53, qui relic la chambre de pompe 52 au reservoir, et un clapet de sortie 54 qui relic la  o The dispensing head of the present invention can be applied to all types of fluid dispensing devices. Figure 4 shows an advantageous embodiment of a dispenser comprising, by way of example, a dispensing head as described above with reference to Figures 1 and 2. n includes a reservoir (not shown) containing the product s distributes, on which is mounted a distribution member, such as a pump SO, which comprises a piston 51, sliding in a pump body, the actuation to said piston S 1 making it possible to selectively distribute the product contained in the reservoir. A pump chamber 52 is defined between an inlet valve 53, which connects the pump chamber 52 to the reservoir, and an outlet valve 54 which connects the

so chambre de pompe 52 au canal de d'expulsion 2 de ladite tete de distribution.  n / a pump chamber 52 to the expulsion channel 2 of said distribution head.

Avantageusement, ['insert rigide 4 est solidaire audit clapet de sortie 54, de sorte ) qu'il est deplace de sa position de repos vers sa position d'actionnement au moment ou le clapet de sortie est ouvert, permettant ltexpulsion du produit de ladite chambre de pompe 52. En particulier, ledit insert rigide 4 forme lui-meme le clapet de sortie de la pompe 50, et ledit insert rigide 4 est deplace de sa s position de repos vers sa position d'actionnement en fin de course d'actionnement du piston 51 de la pompe, garantissant une ouverture et de ltorifice de distribution 3 au moment precis ou le produit contenu dans la chambre de pompe 52 est expulse. En fin d'expulsion de produit, le clapet de sortie est referme, ramenant ['insert 4 dans sa position de repos, ce qui deforme io l'obturateur 10 vers sa position d'obturation (cf. figure 1). L'obturateur est done ouvert et ferme mecaniquement par l'ouverture et la fermeture du clapet de sortie de la pompe 50. Avantageusement, le canal d'expulsion 2, y compris ltorifice de distribution 3, est forme par une tige creuse 55 reliee, notamment de maniere monobloc, au piston 51 de la pompe 50. Ainsi, en cas de tentative d'arrachement i5 de la fete, seul le corps 1 de celle-ci risque d'etre retire, la partie incorporant ltorifice de distribution3 et l'obturation 10 restart solidaire de la pompe. Ceci limite les risques de contamination en cas d'arrachement accidental ou non de la  Advantageously, the rigid insert 4 is integral with said outlet valve 54, so that) it is moved from its rest position to its actuation position when the outlet valve is open, allowing the product to be expelled from said pump chamber 52. In particular, said rigid insert 4 itself forms the outlet valve of the pump 50, and said rigid insert 4 is moved from its rest position to its actuation position at the end of travel. actuation of the piston 51 of the pump, guaranteeing an opening and the dispensing orifice 3 at the precise moment when the product contained in the pump chamber 52 is expelled. At the end of product expulsion, the outlet valve is closed, returning the insert 4 to its rest position, which deforms the shutter 10 towards its closed position (cf. FIG. 1). The shutter is therefore opened and closed mechanically by opening and closing the outlet valve of the pump 50. Advantageously, the expulsion channel 2, including the distribution orifice 3, is formed by a hollow rod 55 connected, in particular in one piece, to the piston 51 of the pump 50. Thus, in the event of an attempt to tear off the party, only the body 1 of the party risks being withdrawn, the part incorporating the distribution orifice 3 and the shutter 10 restart integral with the pump. This limits the risk of contamination in the event of accidental removal or not of the

tete 1.head 1.
