Description

L'invention concerne un distributeur pour produit pâteux comprenant un poussoir à distribution latérale, ce poussoir coulissant en un mouve­ment rectiligne par rapport à un ou des moyens de guidage fixes par rapport au corps du distributeur.The invention relates to a dispenser for pasty product comprising a pusher with lateral distribution, this pusher sliding in a rectilinear movement relative to one or more fixed guide means relative to the body of the dispenser.

Le document DE-A-3 122 330 décrit un distributeur de ce type, dont le poussoir est muni d'un conduit de distribution à sortie latérale, ce poussoir coulissant axialement par rapport à une partie fixe du distributeur et agissant par son enfoncement sur un ressort de rappel ainsi que sur des moyens d'acheminement du produit pâteux. La jupe tubulaire extérieure de la tête du distributeur porte à sa partie supérieure une portion inclinée servant de butée étanche pour l'orifice de sortie du conduit de distribution du poussoir lorsque celui-ci est relâché.Document DE-A-3,122,330 describes a dispenser of this type, the pusher of which is provided with a distribution duct with lateral outlet, this pusher sliding axially with respect to a fixed part of the dispenser and acting by pushing it in on a return spring as well as on means of conveying the pasty product. The outer tubular skirt of the dispenser head carries at its upper part an inclined portion serving as a sealed stop for the outlet orifice of the dispensing duct of the pusher when the latter is released.

Cette portion inclinée masque alors l'orifice de sortie, mais elle a pour inconvénient de ne pas éliminer les restes de produit pâteux qui peuvent adhérer au conduit de distribution au voisinage de son orifice et être alors gênants, soit qu'ils empêchent d'obtenir ensuite des cordons pâteux de forme régulière, soit qu'ils conduisent à un aspect déplaisant, soit encore qu'ils empêchent de remettre facilement le capot ou le salissent exagérément.This inclined portion then masks the outlet orifice, but it has the disadvantage of not eliminating the remains of pasty product which can adhere to the distribution duct in the vicinity of its orifice and be then bothersome, that is to say that they prevent obtaining then pasty cords of regular shape, either that they lead to an unpleasant appearance, or that they prevent the cover from being easily replaced or excessively dirty it.

La demanderesse a cherché à mettre au point un distributeur amélioré ne présentant pas ces inconvénients.The Applicant has sought to develop an improved distributor that does not have these drawbacks.

EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION

L'invention a pour object un distributeur pour produit comprenant, comme il est connu par DE-A-3 122 330, un poussoir muni d'un conduit de distribu­tion à sortie latérale, ce poussoir coulissant longitudinalement par rapport à une partie fixe du distributeur et agissant sur un moyen de rappel à effet ressort ainsi que sur les moyens d'acheminement du produit pâteux, ledit distributeur comportant un élément de masquage de l'orifice de sortie dudit conduit de distribution en position relâchée du poussoir, cet élément de masquage étant porté par une partie tubulaire extérieure du distributeur et laissant ledit orifice dégagé lorsque ledit poussoir est enfoncé.The object of the invention is a dispenser for a product comprising, as is known from DE-A-3 122 330, a pusher provided with a distribution duct with lateral outlet, this pusher sliding longitudinally with respect to a fixed part of the dispenser and acting on a spring effect return means as well as on the means of conveying the pasty product, said dispenser comprising a member for masking the outlet orifice of said dispensing duct in the released position of the pusher, this masking member being carried by an external tubular part of the dispenser and leaving said orifice released when said pusher is depressed.

Selon l'invention, ledit poussoir coulisse par rapport à ladite partie tubulaire extérieure du distributeur, et la surface d'extrémité entourant ledit orifice de sortie, ainsi que la surface de l'élément de masquage qui est située en regard de ladite surface d'extrémité lorsque le poussoir est relâché, sont toutes deux parallèles à la direction de coulissement du poussoir, l'élément de masquage venant par suite couper la fin du cordon pâteux et râcler ladite surface d'extrémité du conduit de distri­bution lorsqu'on relâche le poussoir.According to the invention, said pusher slides with respect to said outer tubular part of the dispenser, and the end surface surrounding said outlet orifice, as well as the surface of the masking element which is located opposite said surface of end when the pusher is released, are both parallel to the direction of sliding of the pusher, the masking element consequently cutting off the end of the pasty bead and scraping said end surface of the dispensing duct when the pusher is released .

La construction est plus simple que dans le DE-A-3 122 330 et il ne peut pas y voir d'accumulation de résidus pâteux gênants pour le fonction­nement du distributeur.The construction is simpler than in DE-A-3 122 330 and there cannot be any accumulation of pasty residues which are troublesome for the operation of the dispenser.

Le poussoir comprend de préférence une portion centrale comportant un voile d'appui et une paroi latérale extérieur coulissante et une portion de sortie du conduit de distribution dépassant latéralement de cette portion coulissante, cette paroi latérale coulissante du poussoir coulissant à l'intérieur de la partie tubulaire extérieure du distributeur. Du fait du parallélisme de la surface d'extrémité entourant l'orifice de sortie et de la surface de la portion correspondante de l'élément de masquage à la direction de coulissement du poussoir, le relâchement du poussoir entraîne un masquage par mouvement de cisaillement, permettant le tronçonnage de la fin du cordon pâteux et le râclage du pourtour de l'orifice.
On peut remarquer que, lorsque lesdites surfaces parallèles entre elles font un angle faible, en pratique inférieur à 10°, avec la direction de coulissement, on obtient encore un effet de tronçonnage du courant pâteux selon sa viscosité.The pusher preferably comprises a central portion comprising a support veil and a sliding external side wall and an outlet portion of the distribution duct projecting laterally from this sliding portion, this sliding side wall of the sliding pusher inside the part tubular dispenser. Due to the parallelism of the end surface surrounding the outlet orifice and of the surface of the corresponding portion of the masking element in the direction of sliding of the pusher, the relaxation of the pusher results in masking by shearing movement, allowing the cutting of the end of the pasty bead and the scraping of the periphery of the orifice.
It can be noted that, when said surfaces which are parallel to one another make a small angle, in practice less than 10 °, with the sliding direction, there is also obtained a cutting effect of the pasty stream according to its viscosity.

La position de l'élément de masquage, qui fait partie de ladite partie tubulaire extérieure, ainsi que la géométrie du poussoir, et plus préci­ sément la position de l'extrémité de son conduit de distribution et son serrage par ladite paroi latérale extérieure ou paroi de coulissement, sont de préférence tels que l'élément de masquage est à +0 à +0,4 mm de la surface d'extrémité du conduit de distribution, et de préférence à moins de +0,3 mm de cette surface, de façon à obtenir une bonne protection de l'orifice de distribution ainsi que, un râclage efficace de ladite surface d'extrémité du conduit.
Il est préférable d'avoir, pour améliorer le tronçonnage du cordon pâteux par l'élément de masquage, un amincissement du bord actif de cet élément au moyen d'un chanfrein extérieur, ce bord actif étant celui que rencontre d'abord le cordon pâteux une fois le poussoir relâché.The position of the masking element, which is part of said outer tubular part, as well as the geometry of the pusher, and more specifically The position of the end of its distribution duct and its tightening by said external lateral wall or sliding wall are preferably such that the masking element is at +0 to +0.4 mm from the surface of end of the distribution duct, and preferably within +0.3 mm from this surface, so as to obtain good protection of the distribution orifice as well as effective scraping of said end surface of the duct.
It is preferable to have, to improve the cutting of the pasty bead by the masking element, a thinning of the active edge of this element by means of an external chamfer, this active edge being that which first meets the pasty bead once the button is released.

Le bord supérieur ou bord libre de la partie tubulaire extérieure dans laquelle coulisse le poussoir définit avantageusement au moins un niveau d'appui de la portion de sortie dépassant latéralement du poussoir, réglant ainsi le dosage de produit pâteux.The upper edge or free edge of the outer tubular part in which the pusher slides advantageously defines at least one level of support of the outlet portion projecting laterally from the pusher, thereby adjusting the dosage of pasty product.

La partie tubulaire extérieure peut aussi constituer un élément de guidage de l'enfoncement du poussoir e t de protection plus complète de sa portion latérale de sortie. Elle comprend ainsi de préférence une fenêtre dont les bords longitudinaux limitent les déplacements latéraux ou en rotation du poussoir et dont le bord inférieur limite l'enfoncement du poussoir, ainsi qu'un élément de masquage en forme de bandeau relié aux bords de la fenêtre par des joues latérales et surmonté éventuellement par un voile de protection, cet élément de masquage en forme de capuchon protégeant la portion de sortie du conduit de distribution lorsque le poussoir est relâché.The outer tubular part can also constitute a member for guiding the depression of the pusher and more complete protection of its lateral outlet portion. It thus preferably comprises a window, the longitudinal edges of which limit the lateral or rotational movements of the pusher and the lower edge of which limits the penetration of the pusher, as well as a masking element in the form of a strip connected to the edges of the window by side cheeks and possibly surmounted by a protective veil, this masking element in the form of a cap protecting the outlet portion of the dispensing duct when the pusher is released.

Le distributeur de l'invention comporte de préférence, avec sa partie tubulaire extérieure de guidage du poussoir, cette partie tubulaire portant le plus souvent l'élément de masquage, les moyens d'acheminement du produit pâteux et de rappel du poussoir suivants:
- une coupelle tubulaire déformable fixée de façon étanche au corps du distributeur et au poussoir, cette coupelle délimitant une chambre de compression et constituant à la fois l'élément à effet ressort et le moyen de compression sur lequel le poussoir agit par son enfoncement et rappelant ce poussoir en positon relâchée;
- de préférence avec cette coupelle déformable, une cheminée longitu­dinale portée par le dessous du voile d'appui du poussoir à laquelle est fixée du façon étanche une tubulure de sortie de ladite coupelle tubulaire déformable, une partie de ladite cheminée constituant le début du conduit de distribution;
- l'extrémité de ladite tubulure de sortie de la coupelle tubulaire déformable formant, de préférence et de façon particulièrement avantageu­se, avec le dessous du voile d'appui du poussoir la valve d'expulsion du produit pâteux depuis la chambre de compression vers ledit conduit de distribution du poussoir.
Deux structures remarquables de valves d'expulsion de ce type sont décrites dans les exemples.The dispenser of the invention preferably comprises, with its external tubular part for guiding the pusher, this tubular part most often carrying the masking element, the following means for conveying the pasty product and for returning the pusher:
- a deformable tubular cup fixed in leaktight manner to the body of the dispenser and to the pusher, this cup delimiting a compression chamber and constituting both the spring-effect element and the compression means on which the pusher acts by its depression and recalling this pusher in relaxed position;
- Preferably with this deformable cup, a longitudinal chimney carried by the underside of the support veil of the pusher to which is tightly fixed an outlet pipe of said deformable tubular cup, a part of said chimney constituting the beginning of the conduit distribution;
- The end of said outlet tubing of the deformable tubular cup preferably, and particularly advantageously, with the underside of the support veil of the pusher the valve for expelling the pasty product from the compression chamber to said conduit dispenser.
Two remarkable structures of such expulsion valves are described in the examples.

La position de l'élément de masquage de l'invention peut être suffisam­ment en retrait pour ne pas empêcher ou gêner l'enfoncement d'un capot de présentation et de propreté: elle peut par exemple correspondre au diamètre de la portion de la partie tubulaire extérieure que vient ceinturer l'extrémité de la jupe de ce capot.The position of the masking element of the invention can be set back enough not to prevent or hinder the penetration of a presentation and cleanliness cover: it can for example correspond to the diameter of the portion of the tubular part outside that comes to surround the end of the skirt of this cover.

Enfin, lorsque l'élément de masquage est en forme de bandeau relié à la partie tubulaire extérieure par des joues latérales, la portion de sortie du conduit de distribution du poussoir se trouvant au repos insérée dans ce bandeau en U, le distributeur est avantageusement rendu inviolable au moyen d'une plaquette reliée par des ponts cassables aux bas des joues latérales du bandeau, cette plaquette réalisée au moulage de ladite partie tubulaire extérieure empêchant un enfoncement non contrôlé du poussoir et rendant manifeste le premier usage du distri­buteur.Finally, when the masking element is in the form of a strip connected to the external tubular part by lateral cheeks, the outlet portion of the pusher distribution duct being at rest inserted in this U-shaped strip, the dispenser is advantageously returned inviolable by means of a plate connected by breakable bridges at the bottom of the side cheeks of the strip, this plate produced by molding said outer tubular part preventing uncontrolled penetration of the pusher and making manifest the first use of the dispenser.

Les exemples illustrent les modes de réalisation et certaines particu­larités avantageuses du distributeur de l'invention.The examples illustrate the embodiments and certain advantageous features of the dispenser of the invention.

Le poussoir 1 de la figure 1 comprend un voile supérieur 2 servant d'appui et une paroi latérale cylindrique circulaire 3 interrompue par l'émergence sensiblement radiale de la portion de sortie 4 du conduit de distribution 5 du produit pâteux. Ce conduit 5 a une section droite ovalisée aplatie sur ses parois inférieure 6 et supérieure 7 qui sont en leurs parties centrales perpendiculaires à l'axe X de symétrie corres­pondant à la direction coulissement du poussoir 1. Dans la partie du conduit 5 qui est intérieure à la paroi latérale 3, sa paroi supé­rieure 7 est confondue avec le voile supérieur 2 du poussoir 1. Le conduit 5 débouche dans une cheminée centrale cylindrique circulaire 8 qui, à l'assemblage, est fixée de façon étanche par la gorge 9 sur une coupelle tubulaire déformable du type représenté sur la figure 5 ou de celui des figures 6 et 7.The pusher 1 of FIG. 1 comprises an upper veil 2 serving as a support and a circular cylindrical side wall 3 interrupted by the substantially radial emergence of the outlet portion 4 of the distribution conduit 5 of the pasty product. This duct 5 has an oval cross-section flattened on its lower 6 and upper 7 walls which are in their central parts perpendicular to the axis X of symmetry corresponding to the sliding direction of the pusher 1. In the part of the duct 5 which is internal to the side wall 3, its upper wall 7 coincides with the upper web 2 of the pusher 1. The conduit 5 opens into a circular central cylindrical chimney 8 which, when assembled, is tightly fixed by the groove 9 on a cup deformable tubular of the type shown in FIG. 5 or of that of FIGS. 6 and 7.

Le moyen de guidage à ce poussoir 1 est une partie tubulaire extérieure 10 de même axe X que le poussoir 1, la portion supérieure 11 de cette partie 10 étant cylindrique circulaire et ayant un jeu diamétral de 0,2 mm par rapport à la paroi latérale 3 du poussoir 1 qui coulisse axialement dans cette portion 10. Cette portion supérieure 11 comporte à l'endroit de l'émergence de la portion de sortie 4 du poussoir 1 une fenêtre 12 de passage de cette portion de sortie 4 surmon­tée par un élément de masquage fixe 13 en forme de visière, dont la surface intérieure 14 vient s'appliquer sur l'orifice 16 et sur son pourtour 17 en position relâchée du poussoir. Cette surface intérieure 14 et la surface du pourtour 17 de l'orifice 16 sont légèrement incur­vées, parallèles entre elles et inclinées à environ 25° par rapport à l'axe X.
L'élément de masquage 13 comporte à sa partie supérieure un petit rebord horizontal 18 qui complète la protection de l'extrémité du conduit 5 en position relâchée du poussoir 1, et arrête la remontée de ce pous­soir 1 environ 1 mm avant sa montée complète, de sorte que l'extrémité 16 et 17 du conduit 5 est, au repos, appliquée élastiquement contre l'élément de masquage 13, réalisant ainsi un bouchage étanche. Le bord supérieur de l'élément de masquage 13 se raccorde par deux bords obli­ques 19 au bord d'extrémité supérieure 20 de la partie arrière de la portion de coulissement 11. Ce bord 20 est perpendiculaire à l'axe X et est 0,5 à 1 mm au-dessous du voile d'appui 2 du poussoir 1 lorsque celuici est enfoncé, de sorte que le guidage du poussoir 1 reste bon dans cette position. L'operculage par simple appui élastique qui est réalisé ici est particulièrement intéressant pour des produits pâteux de viscosité assez faible ou moyenne, dont les adhérences de produit pâteux sont limitées.The guide means to this pusher 1 is an outer tubular part 10 of the same axis X as the pusher 1, the upper portion 11 of this part 10 being circular cylindrical and having a diametral clearance of 0.2 mm relative to the side wall 3 of the pusher 1 which slides axially in this portion 10. This upper portion 11 comprises at the point of emergence of the outlet portion 4 of the pusher 1 a window 12 for passage of this outlet portion 4 surmounted by an element of fixed masking 13 in the form of a visor, the inner surface 14 of which is applied to the orifice 16 and on its periphery 17 in the released position of the pusher. This inner surface 14 and the surface of the periphery 17 of the orifice 16 are slightly curved, mutually parallel and inclined at about 25 ° relative to the axis X.
The masking element 13 has at its upper part a small horizontal flange 18 which completes the protection of the end of the conduit 5 in the released position of the pusher 1, and stops the ascent of this pusher 1 approximately 1 mm before its complete rise, so that the end 16 and 17 of the conduit 5 is, at rest, applied elastically against the masking element 13, thus achieving a tight closure. The upper edge of the masking element 13 is connected by two oblique edges 19 to the upper end edge 20 of the rear part of the sliding portion 11. This edge 20 is perpendicular to the axis X and is 0.5 1 mm below the support web 2 of the pusher 1 when it is depressed, so that the guidance of the pusher 1 remains good in this position. The sealing by simple elastic support which is carried out here is particularly advantageous for pasty products of fairly low or medium viscosity, whose adhesions of pasty product are limited.

Dans le distributeur des figures 2 et 3, il y a une modification impor­tante par rapport au premier distributeur: le pourtour 117 de l'orifice 116 du conduit 105 du poussoir 101 et la surface intérieure 114 de l'élément de masquage 113 sont tous deux parallèles à la direction de coulissement X du poussoir 101. En comparant la figure 2 (position enfoncée du poussoir 101) et la fig. 3 (position relâchée du poussoir), on voit que lorsque le poussoir 101, soumis à la détente d'un élément à effet ressort qu'il a comprimé par son enfoncement, remonte, sa surface d'extrémité 116 et 117 se déplace en un mouvement de cisaillement vis-­à-vis de la surface 114 de l'élément de masquage. Le poussoir 101 et la partie tubulaire extérieure de guidage 110 sont tous deux en polypro­pylène moulé, avec des épaisseurs de 1 à 1,2 mm pour les parties jouant un rôle dans les positionnements, et ont les dimensions suivantes selon le plan de coupe:
. diamètre intérieur cylindrique circulaire de la portion supérieure de coulissement 111 de la partie de guidage 110 = 22,2 mm
. diamètre extérieur de la paroi latérale cylindrique circulaire 103 du poussoir 101 = 22,1 mm
. dimension hors-tout du poussoir 101 selon le plan de coupe = 25,9 mm
. distance entre les prolongements des surfaces intérieures 114 de l'élément de masquage 113 et de la portion de coulissement 111 qui lui est opposée, selon l'axe du conduit de distribution 105 = 26,0 mm.In the dispenser of FIGS. 2 and 3, there is an important modification compared to the first dispenser: the periphery 117 of the orifice 116 of the duct 105 of the pusher 101 and the interior surface 114 of the masking element 113 are both parallel to the sliding direction X of the pusher 101. By comparing FIG. 2 (depressed position of the pusher 101) and FIG. 3 (released position of the pusher), it can be seen that when the pusher 101, subjected to the expansion of a spring-effect element which it has compressed by its depression, rises, its surface end 116 and 117 moves in a shearing movement with respect to the surface 114 of the masking element. The pusher 101 and the outer tubular guide part 110 are both made of molded polypropylene, with thicknesses of 1 to 1.2 mm for the parts playing a role in the positioning, and have the following dimensions according to the cutting plane:
. circular cylindrical inner diameter of the upper sliding portion 111 of the guide portion 110 = 22.2 mm
. outer diameter of the circular cylindrical side wall 103 of the pusher 101 = 22.1 mm
. overall dimension of pusher 101 according to the cutting plane = 25.9 mm
. distance between the extensions of the interior surfaces 114 of the masking element 113 and of the sliding portion 111 which is opposite to it, along the axis of the distribution duct 105 = 26.0 mm.

On a constaté qu'avec cette disposition, les éléments intérieurs en rapport avec le mouvement du poussoir étant représentés sur les figures 6 et 7, on obtenait un très bon cisaillement des extrémités de cordon pâteux assez visqueux et un râclage de l'orifice 116 et de son pourtour 117, permettant d'éviter les inconvénients liés au séchage et durcis­sement des résidus pâteux dépassant de l'orifice 116 ou adhérant à son pourtour 117.It was found that with this arrangement, the internal elements in relation to the movement of the pusher being represented in FIGS. 6 and 7, very good shearing of the ends of the fairly viscous pasty bead was obtained and a scraping of the orifice 116 and of its periphery 117, making it possible to avoid the drawbacks linked to the drying and hardening of the pasty residues projecting from the orifice 116 or adhering to its periphery 117.

Pour obtenir de tels résultats, on observe typiquement les conditions suivantes: jeu diamétral de coulissement du poussoir 101 dans la portion de coulissement 111 de la partie de guidage 110 = 0,2 mm au maximum; et jeu entre le poussoir 101 et la partie de guidage 110 à l'endroit de l'extrémité 117 du conduit de distribution 105 et de l'élément de masquage 113 = inférieur à 0,3 mm.
Le bord inférieur de l'élément de masquage 113 est aminci par un chan­frein extérieur 1132, ce qui de façon générale améliore le cisaillement des extrémités de cordon pâteux assez visqueux.To obtain such results, the following conditions are typically observed: diametral sliding play of the pusher 101 in the sliding portion 111 of the guide portion 110 = 0.2 mm maximum; and play between the pusher 101 and the guide part 110 at the end 117 of the distribution conduit 105 and the masking element 113 = less than 0.3 mm.
The lower edge of the masking element 113 is thinned by an external chamfer 1132, which generally improves the shearing of the ends of fairly viscous pasty bead.

Sur la figure 4 (vue de dessus), on voit que le voile supérieur 102 du poussoir 101 comporte de légers chanfreins arrondis tels que 1020. Le poussoir 101 est encastré avec un jeu faible dans la partie tubulaire extérieure 110, jeu de 0,1 mm au diamètre pour les zones cylindriques circulaires et, en position relâchée du poussoir 0,3 à 0,4 mm entre la portion de sortie 104 et les joues latérales 1130 de l'élément de masquage 113. Au-delà des joues latérales 1130, le bord supérieur de la partie extérieure 110 se continue par deux bords obliques 119 (figures 2 et 4) qui se raccordent un peu au-delà de la demi-circonférence à sa partie arrière 120 perpendiculaire à l'axe de coulissement X, ce qui donne un bon compromis entre la facilité d'appui du poussoir 101 par l'utilisateur et la rigidité de son guidage lors de sa remontée. Plus précisément, le bord supérieur arrière 120 s'étend ici, entre les points de raccordements 1190, sur 140° et il est en pratique souhai­table que cette étendue reste comprise entre 100 et 160°. La surface extérieure frontale 1131 de l'élément de masquage 113 surplombe la partie cylindrique circulaire 121 autour de laquelle le capot de protec­tion (voir figure 6) doit s'ajuster, elle est à l'aplomb ou légèrement en retrait de cette surface cylindrique 121 pour ne pas gêner la mise en place de ce capot.In FIG. 4 (top view), it can be seen that the upper web 102 of the pusher 101 has slight rounded chamfers such as 1020. The pusher 101 is embedded with a small clearance in the external tubular part 110, clearance of 0.1 mm in diameter for the circular cylindrical zones and, in the released position of the pusher 0.3 to 0.4 mm between the outlet portion 104 and the side cheeks 1130 of the masking element 113. Beyond the side cheeks 1130, the upper edge of the outer part 110 is continued by two oblique edges 119 (FIGS. 2 and 4) which connect a little beyond the half-circumference to its rear part 120 perpendicular to the sliding axis X, which gives a good compromise between the ease of support of the pusher 101 by the user and the rigidity of its guidance during its ascent. More specifically, the rear upper edge 120 extends here, between the connection points 1190, over 140 ° and it is in practice desirable for this extent to remain between 100 and 160 °. The front external surface 1131 of the masking element 113 overhangs the circular cylindrical part 121 around which the protective cover (see FIG. 6) must adjust, it is plumb or slightly set back from this cylindrical surface 121 so as not to hinder the installation of this cover.

La figure 5 montre le haut d'un troisième distributeur équipé d'une coupelle tubulaire déformable 22 en polyester-éther, fixée dans la cheminée centrale 8 du poussoir 201 par sa tubulaire supérieure 23 dont la nervure extérieure 230 est encliquetée dans la gorge intérieure 9 du bas de cette cheminée 8.FIG. 5 shows the top of a third distributor equipped with a deformable tubular cup 22 in polyester-ether, fixed in the central chimney 8 of the pusher 201 by its upper tubular 23 whose outer rib 230 is snapped into the inner groove 9 from the bottom of this chimney 8.

Ce troisième distributeur a la même pièce tubulaire de guidage 110 que le deuxième distributeur, et le poussoir 201 est identique au pous­soir 101 à l'exception du fond de la cheminée 8 qui est lisse alors que dans le deuxième distributeur il comporte (figure 3 par exemple) une petite tubulaire axiale 124. La tubulure supérieure 23 de sa coupelle déformable 22 se termine par une lèvre souple amincie évasée 230 d'épais­seur 0,2 mm à son extrémité, qui s'applique élastiquement de façon étanche contre le fond de la cheminée 8, c'est-à-dire contre la surface de dessous du voile d'appui 202. La coupelle déformable 22 comprend au-dessous de la tubulure supérieure 23 un voile déformable 24 en forme de dôme aminci d'épaisseur 0,9 mm, puis une tubulure inférieure semi-­rigide 25 et un rebord inférieur 26 de fixation entre le bas de la pièce de guidage 110 et le sommet 27 du corps tubulaire 28 du distribu­teur. La coupelle déformable 22 délimite une chambre de compression 29, dont le clapet d'aspiration n'est pas représenté dans la figure 5 mais est identique à celui du deuxième distributeur (figures 6 et 7), et dont la valve d'expulsion du produit pâteux dans le conduit de distribution 205 est formée par la lèvre élastique 230 et par le dessus du voile d'appui 202 qui est aussi la paroi du conduit 205. Cette disposition donne un guidage et une remontée particulièrement fiables du poussoir 201, aboutissant à une bonne reproductibilité des effets de l'élément de masquage 113 : cisaillement de cordons pâteux assez visqueux, râclage de l'orifice d'extrémité du conduit de distribu­tion 205 et don son pourtour, operculage de cet orifice avec un jeu faible.This third distributor has the same tubular guide piece 110 as the second distributor, and the pusher 201 is identical to the pusher 101 with the exception of the bottom of the chimney 8 which is smooth whereas in the second distributor it comprises (FIG. 3 by example) a small axial tubular 124. The upper tubing 23 of its deformable cup 22 ends in a tapered flexible flexible lip 230 of thickness 0.2 mm at its end, which is applied elastically in leaktight manner against the bottom of the chimney 8, that is to say against the bottom surface of the support web 202. The deformable cup 22 comprises below the upper tube 23 a deformable web 24 in the form of a thinned dome with a thickness of 0.9 mm, then a semi-rigid lower tube 25 and a lower flange 26 for fixing between the bottom of the guide piece 110 and the top 27 of the tubular body 28 of the dispenser. The deformable cup 22 delimits a compression chamber 29, the suction valve of which is not shown in FIG. 5 but is identical to that of the second distributor (FIGS. 6 and 7), and the product expulsion valve of which pasty in the distribution conduit 205 is formed by the elastic lip 230 and by the top of the support veil 202 which is also the wall of the conduit 205. This arrangement gives particularly reliable guidance and ascent of the pusher 201, resulting in a good reproducibility of the effects of the masking element 113: shearing of fairly viscous pasty cords, scraping of the end orifice of the distribution conduit 205 and giving its periphery, sealing of this orifice with little play.

Les figures 6 et 7 montrent le haut du deuxième distributeur, respecti­vement avant la première utilisation et en utilisation, le poussoir 101 étant alors enfoncé. Pour le stockage et la vente, l'élément de masquage 113, que ne comporte pas de rebord supérieur de façon, à permet­tre l'introduction du poussoir 101 par le haut de l'élément tubulaire de guidage 110 lors de l'assemblage du distributeur, est muni à sa partie inférieure, au-dessous de la portion de sortie 104 du conduit de distribution 105 du poussoir 101 à l'état relâché, d'une plaquette 30 reliée au bas des joues latérales telles que 1130 (figure 4) par des ponts cassables. Un capot 31 de protection et de présentation est en place, sans obstacles provenant de l'élément de masquage 113 comme cela a été commenté à propos de la figure 4. Après enlèvement du capot 31, il suffira d'enfoncer le poussoir 101 de 1,5 à 2 mm pour obtenir la rupture des ponts cassables et la chute de la plaquette d'inviolabi­lité 30, alors que l'enfoncement maximal du poussoir 101 (position de la figure 7) est de 9 mm.Figures 6 and 7 show the top of the second distributor, respectively before the first use and in use, the pusher 101 is then pressed. For storage and sale, the masking element 113, which does not have an upper rim so as to allow the introduction of the pusher 101 from the top of the tubular guide element 110 during assembly of the dispenser , is provided at its lower part, below the outlet portion 104 of the distribution duct 105 of the pusher 101 in the relaxed state, with a plate 30 connected to the bottom of the side cheeks such as 1130 (FIG. 4) by breakable bridges. A protective and presentation cover 31 is in place, without obstacles coming from the masking element 113 as has been commented on in connection with FIG. 4. After removal of the cover 31, it will suffice to depress the pusher 101 of 1 , 5 to 2 mm to obtain the rupture of the breakable bridges and the fall of the tamper-evident plate 30, while the maximum insertion of the pusher 101 (position of FIG. 7) is 9 mm.

Le poussoir 101 est fixé sur une coupelle tubulaire déformable 32, dont seule l'extrémité supérieure de la tubulure supérieure 33 diffère de l'extrémité supérieure 230 de la tubulure supérieure 23 de la coupelle 22 du deuxième distributeur. Cette extrémité supérieure 33 comporte un bord annulaire d'extrémité 34 et un disque souple 35 dont la périphé­rie est maintenue en appui sur le bord 34 par l'appui de la tubulure axiale 124, le disque portant une tige de centrage 36 axiale qui vient s'emboîter dans la tubulure axiale 124, ce qui assure un bon centrage de cet élément souple 35 qui forme avec le bord annulaire 34 de la valve d'expulsion 34 et 35 du distributeur.The pusher 101 is fixed to a deformable tubular cup 32, of which only the upper end of the upper tube 33 differs from the upper end 230 of the upper tube 23 of the cup 22 of the second distributor. This upper end 33 comprises an annular end edge 34 and a flexible disc 35 the periphery of which is held in abutment on the edge 34 by the support of the axial tube 124, the disk carrying an axial centering rod 36 which fits into the tube axial 124, which ensures good centering of this flexible element 35 which forms with the annular edge 34 of the expulsion valve 34 and 35 of the dispenser.

En outre, ce qui est avantageux pour l'assemblage, le dessous du disque souple 35 est relié à l'intérieur de la tubulure supérieure 33 par trois joncs souples 37 espacés à 120°, de section droite 1 x 0,6 mm. L'épaisseur du disque souple est, en dehors de sa zone centrale, de 0,3 mm. En elle-même, cette valve d'expulsion 34 et 35, réalisée ici monobloc avec le reste de la coupelle tubulaire déformable 32, permet un passage de produit pâteux plus facile que la valve d'expulsion de la figure 4 et une remontée plus rapide du poussoir 101, ce qui favorise le couplage et le râclage par l'élément de masquage 113. Des résultats seront indiqués plus loin.In addition, which is advantageous for assembly, the underside of the flexible disc 35 is connected to the interior of the upper tube 33 by three flexible rods 37 spaced at 120 °, of cross section 1 x 0.6 mm. The thickness of the flexible disk is, outside its central zone, 0.3 mm. In itself, this expulsion valve 34 and 35, produced here in one piece with the rest of the deformable tubular cup 32, allows passage of pasty product easier than the expulsion valve of FIG. 4 and a faster rise pusher 101, which promotes coupling and scraping by the masking element 113. Results will be indicated below.

Le deuxième, comme le troisième distributeur, comprend (figures 6 et 7) à la base de la chambre de compression 38 délimitée par la coupelle déformable 32 une soupape 39 et 40 d'aspiration du produit pâteux contenu dans la chambre de stockage surmontant un piston de fond glissant (non représenté) dans ladite chambre de compression 38, cette aspiration se faisant ici selon des directions sensiblement radiales représentées sur la figure 6 par la flèche 41. Le sommet du corps tubulaire comporte une cloison transversale 42 séparant la chambre de stockage de la chambre de compression 38, et cette cloison 42 comporte un orifice de passage 43 de diamètre 22 mm entouré d'une surface annulaire 39 constituant le siège de la soupape d'aspiration 39 et 40, le clapet 40 de cette soupape comprenant un voile supérieur débordant 44, dont le rebord annulaire s'applique de façon étanche sur la surface annulaire 39 en position de fermeture de la soupape (figure 7) et d'une portion sous-­jacente 44 munie à sa partie inférieure d'un ou plusieurs reliefs de retenue de diamètre hors-tout supérieure de 0,4 à 2 mm au diamètre dudit orifice de passage 43, ce diamètre hors-tout permettant l'enclique­tage initial du clapet 40 au travers de cet orifice.
Dans le cas présent, la portion sous-jacente 44 comporte 12 reliefs espacés radiaux tels que 45 et 45′, dont les bords longitudinaux tels que 46, de diamètre hors-tout 21 mm, servent de moyens de guidage du clapet 40 dans l'orifice 43, ainsi qu'un jonc de retenue 47 de contour circulaire, supporté par les reliefs 45. Le voile d'obturation 44 du clapet 40 comporte une zone centrale en creux 48, le dessous de cette zone 48 étant à une hauteur intermédiaire des fenêtres de passage du produit pâteux délimitées par le rebord annulaire du voile 44, les reliefs tels que 45 et 45′, et le jonc circulaire 47, ce qui facilite le passage du produit pâteux à travers le clapet 40 tout en permettant un écrasement plus prononcé de l'élément de pompage 32 (figure 7). La course axiale du clapet 40 de l'orifice 43 est de 3 mm.The second, like the third distributor, comprises (FIGS. 6 and 7) at the base of the compression chamber 38 delimited by the deformable cup 32 a valve 39 and 40 for suction of the pasty product contained in the storage chamber surmounting a piston sliding bottom (not shown) in said compression chamber 38, this aspiration taking place here in substantially radial directions represented in FIG. 6 by arrow 41. The top of the tubular body comprises a transverse partition 42 separating the storage chamber from the compression chamber 38, and this partition 42 comprises a passage orifice 43 of 22 mm diameter surrounded by an annular surface 39 constituting the seat of the suction valve 39 and 40, the valve 40 of this valve comprising an upper web protruding 44, the annular rim of which presses tightly on the annular surface 39 in the closed position of the valve (FIG. 7) and of an underlying portion 44 provided with its lower part of one or more retaining reliefs with an overall diameter greater than 0.4 to 2 mm in diameter of said passage orifice 43, this overall diameter allowing the initial clipping of the valve 40 through this orifice .
In the present case, the underlying portion 44 has 12 reliefs radial spaces such as 45 and 45 ′, the longitudinal edges of which, such as 46, with an overall diameter of 21 mm, serve as means for guiding the valve 40 in the orifice 43, as well as a retaining ring 47 of circular outline , supported by the reliefs 45. The closing veil 44 of the valve 40 has a central hollow area 48, the underside of this area 48 being at an intermediate height of the pasty product passage windows delimited by the annular edge of the veil 44 , the reliefs such as 45 and 45 ′, and the circular rod 47, which facilitates the passage of the pasty product through the valve 40 while allowing more pronounced crushing of the pumping element 32 (Figure 7). The axial stroke of the valve 40 of the orifice 43 is 3 mm.

Au cours des essais qui ont été faits, on a trouvé que la disposition de la valve d'expulsion 34 et 35 du diamètre distributeur était nettement meilleure que celle de la valve d'expulsion 230 et 202 du troisième distributeur, l'effort d'expulsion, repéré par l'effort sur le poussoir nécessaire pour obtenir la distribution du produit pâteux, passant de plus de 4 kg à environ 2,5 kg, et l'énergie disponible pour la coupe ou le râclage des débris pâteux étant plus grande. On a déterminé aussi que la disposition du clapet 40, facilitant le passage du produit pâteux en diminuant l'énergie d'aspiration, permettrait de conserver un temps de remontée du poussoir faible lorsqu'on diminuait l'épaisseur du voile déformable 48 de la coupelle tubulaire déformable 32 de façon à réduire encore l'effort nécessaire sur le poussoir 101. L'ensemble des deux dispositions est ainsi particulièrement avantageux, en particulier pour la bonne utilisation de l'élément de masquage de l'invention dans ses fonctions de râclage et de coupe de débris ou extrémités de produit pâteux.
La coupelle tubulaire déformable est de préférence en l'une des matières du groupe formé par: les polymères thermoplastiques, les résines silicones, les caoutchoucs. La soupape d'aspiration, typiquement en PE moyenne ou haute densité ou en PP, est avantageusement, et c'est le cas ici, réalisée monobloc et en même temps que le sommet du corps tubulaire, la partie inférieure de sa portion sous-jacente 44 en-dessous de ses reliefs de retenue 45 étant reliée au bord de l'orifice de passage 43 par un film périphérique cassable, la cassure de cette liaison et l'encliquetage des reliefs 45 se faisant ensuite dans une même poussée.During the tests which were made, it was found that the arrangement of the expulsion valve 34 and 35 of the distributor diameter was much better than that of the expulsion valve 230 and 202 of the third distributor, the effort of expulsion, identified by the effort on the pusher necessary to obtain the distribution of the pasty product, passing from more than 4 kg to approximately 2.5 kg, and the energy available for cutting or scraping pasty debris being greater. It has also been determined that the arrangement of the valve 40, facilitating the passage of the pasty product by reducing the suction energy, would make it possible to keep the lift time of the pusher low when the thickness of the deformable veil 48 of the cup was reduced. deformable tubular 32 so as to further reduce the force required on the pusher 101. The combination of the two arrangements is thus particularly advantageous, in particular for the proper use of the masking element of the invention in its scraping functions and cutting debris or ends of pasty product.
The deformable tubular cup is preferably made of one of the materials of the group formed by: thermoplastic polymers, silicone resins, rubbers. The suction valve, typically made of medium or high density PE or PP, is advantageously, and this is the case here, made in one piece and at the same time as the top of the tubular body, the lower part of its underlying portion. 44 below its retaining reliefs 45 being connected to the edge of the passage orifice 43 by a frangible peripheral film, the breaking of this connection and the snapping of the reliefs 45 then taking place in the same push.

L'invention trouve son application dans les distributeurs de produits pâteux ou de crèmes dans les domaines cosmétologiques, hygiéniques, pharmaceutiques et alimentaires.The invention finds its application in distributors of pasty products or creams in the cosmetological, hygienic, pharmaceutical and food fields.
