Description

L'invention a pour objet un tampon souple pour produit à étaler tel que cirage, crème pour l'entretien du cuir, cire liquide, peinture, etc...The subject of the invention is a flexible pad for spreading product such as shoe polish, leather care cream, liquid wax, paint, etc.

Les tampons connus de ce genre comprennent un support semi-rigide réalisé généralement en polyéthylène et un bloc convenablement dimensionné, en matière souple comme de la mousse d'une matière plastique, à cellules ouvertes, de préférence une mousse de polyester.Known pads of this kind comprise a semi-rigid support generally made of polyethylene and a suitably dimensioned block, of flexible material such as foam of a plastic material, with open cells, preferably a polyester foam.

Un tel support comprend un manchon souple destiné à être monté comme un bouchon ou comme un couvercle à une extrémité ouverte d'un flacon ou d'un tube et il a une surface extérieure plane à laquelle adhère fermement le bloc de mousse. Le volume intérieur du manchon est prolongé par un canal qui est lui-même prolongé par un canal prévu dans le bloc de mousse ; ces canaux servent à l'arrivée du produit que le bloc de mousse sert à étaler. La section droite du canal prévu dans le bloc de mousse est déterminée en fonction de l'écoulement désiré et de la viscosité du produit à étaler.Such a support comprises a flexible sleeve intended to be mounted as a stopper or as a cover at an open end of a vial or a tube and it has a flat outer surface to which the block of foam adheres firmly. The interior volume of the sleeve is extended by a channel which is itself extended by a channel provided in the foam block; these channels are used for the arrival of the product that the foam block is used to spread. The cross section of the channel provided in the foam block is determined according to the desired flow and the viscosity of the product to be spread.

Il est courant de monter à l'intérieur du manchon et dans le canal ménagé dans le support un dispositif à soupape et à ressort afin d'empêcher l'écoulement libre du produit. Pour faire sortir ce dernier, on doit écraser le bloc de mousse contre une surface à enduire ; cet écrase­ment du bloc permet de pousser la tige de la soupape, d'éloi­gner celle-ci de son siège et de laisser sortir la quantité désirée de produit à étaler.It is common to mount inside the sleeve and in the channel provided in the support a valve and spring device in order to prevent the free flow of the product. To remove the latter, you must crush the foam block against a surface to be coated; this crushing of the block makes it possible to push the valve stem, to move it away from its seat and to let out the desired quantity of product to be spread.

Le support est en polyéthylène parce que seule cette matière réunit les qualités exigées : la facilité de réalisation en grande série par injection dans un moule, à une température de 180°C environ, la rigidité suffisante à l'emploi, la souplesse nécessaire à l'usage de ce support comme bouchon d'un flacon ou d'un tube au col rigide auquel le support doit s'adapter, le caractère hydrophobe qui le rend non mouillable par le produit à étaler et qui faci­lite l'écoulement de ce produit.The support is made of polyethylene because only this material meets the required qualities: the ease of production in large series by injection into a mold, at a temperature of about 180 ° C, the rigidity sufficient for use, the flexibility necessary for the use of this support as a stopper for a bottle or a tube with a rigid neck to which the support must adapt, the hydrophobic nature which makes it non-wettable by the product to be spread and which facilitates the flow of this product.

Si le polyéthylène présente toutes ces qualités désirées à un degré convenable il a aussi une propriété dont les conséquences ne sont pas appréciables en toutes circonstances. Il est pratiquement impossible de l'assembler à d'autres pièces par collage. Autrement dit, il n'existe pas de colle ou d'adhésif utilisable pour la fixation à froid du polyéthylène. Cette propriété découle de sa bonne résistance à la plupart des solvants, ce qui est appréciable vis- à-vis des produits à étaler, mais cette même propriété oblige à utiliser un procédé de fixation à chaud pour exécuter l'opération de liaison entre le bloc de mousse et le support semi-rigide.If polyethylene has all these desired qualities to a suitable degree, it also has a property whose consequences are not appreciable in all circumstances. It is practically impossible to assemble it with other parts by gluing. In other words, there is no glue or adhesive which can be used for cold fixing of polyethylene. This property results from its good resistance to most solvents, which is appreciable with regard to the products to be spread, but this same property obliges to use a hot fixing process to carry out the bonding operation between the block. foam and the semi-rigid support.

On trouvera un exemple d'emploi de ce procédé de fixation à chaud dans le document GB-A-1.254.957.An example of the use of this hot fixing method can be found in document GB-A-1,254.957.

De ce fait, la fabrication des tampons souples comportant une opération de fixation à chaud, c'est-à-dire le ramollissement préalable jusqu'à la fusion d'une zone superficielle du support en polyéthylène et l'application sous pression du bloc de mousse contre cette zone ramollie, avant sa solidification, cette fabrication ne peut se faire, nécessairement, qu'à une cadence assez peu élevée ; en outre elle nécessite la mise en oeuvre d'une énergie de chauffage non négligeable, peu désirable en raison du faible coût souhaité des tampons souples.As a result, the manufacture of flexible pads comprising a hot fixing operation, that is to say the prior softening until the melting of a surface area of the polyethylene support and the application under pressure of the block of foam against this softened area, before its solidification, this manufacture can only be done, necessarily, at a relatively low rate; in addition it requires the implementation of a significant heating energy, undesirable because of the low cost desired flexible pads.

L'invention a pour but principal d'apporter un tampon souple du genre défini plus haut mais de conception nouvelle supprimant la nécessité d'une liaison à chaud entre le support et le bloc de mousse et autorisant, au contraire, une fixation à froid du bloc de mousse par rapport au support en polyéthylène.The main object of the invention is to provide a flexible buffer of the kind defined above but of a new design eliminating the need for a hot connection between the support and the foam block and authorizing, on the contrary, a cold fixing of the foam block in relation to the polyethylene support.

Dans un tampon souple pour produit à étaler, comprenant d'une part un support en polyéthylène, ou en matière à propriété analogue, ayant à une partie extrême un manchon souple et à son extrémité opposée un plateau transversal de fermeture à face extrême située dans un plan transversal à la dimension longitudinale du manchon, avec un canal s'étendant à travers ce plateau dans le prolongement du volume intérieur du manchon et s'ouvrant dans la face extrême de ce plateau, d'autre part un bloc en mousse de matière plastique ayant une face extrême proche de la face extrême du plateau, cette face extrême du plateau ayant un bord périphérique extérieur et un bord périphérique intérieur, selon l'invention, le tampon comprend en plus une rondelle de dimensions sensiblement égales à celles de la face extrême avec un bord périphérique extérieur et un bord périphérique intérieur ; cette rondelle est en matière susceptible de collage à froid et peut être appliquée par une de ses faces contre ladite face extrême, cependant qu'il existe sur l'un au moins des bords périphéri­ques extérieurs et intérieurs de la face extrême et de la rondelle, au moins en deux points espacés de ce bord, un moyen de retenue qui retient la rondelle appliquée contre la face extrême du plateau, le bloc de mousse étant fixé par collage à froid à la face de cette rondelle opposée à celle qui est appliquée contre la face extrême du plateau.In a flexible pad for spreading product, comprising on the one hand a support made of polyethylene, or of a material having a similar property, having at one end a flexible sleeve and at its opposite end a transverse closure plate with end face located in a plane transverse to the longitudinal dimension of the sleeve, with a channel extending through this plate in the extension of the interior volume of the sleeve and opening in the end face of this plate, on the other hand a block of plastic foam having an end face close to the end face of the tray, this end face of the tray having an outer peripheral edge and an inner peripheral edge, according to the invention, the pad further comprises a washer of dimensions substantially equal to those of the end face with an outer peripheral edge and an inner peripheral edge ; this washer is made of material capable of cold bonding and can be applied by one of its faces against said end face, while it exists on at least one of the external and internal peripheral edges of the end face and of the washer, at least at two points spaced from this edge, a retaining means which retains the washer applied against the end face of the plate, the foam block being fixed by cold gluing to the face of this washer opposite to that which is applied against the extreme face of the plate.

De préférence, la rondelle est en matière plastique rigide attaquable par un composant d'une colle appropriée comme le polystyrène, le polychlorure de vinyle, le polymé­thacrylate.Preferably, the washer is made of rigid plastic material which can be attacked by a component of an appropriate adhesive such as polystyrene, polyvinyl chloride, polymethacrylate.

Dans un exemple de réalisation de l'invention le bord périphérique extérieur de la face extrême du plateau est muni sur la totalité de sa longueur d'une lèvre souple de retenue ayant une hauteur supérieure à l'épaisseur de la rondelle ; de préférence cette lèvre est légèrement inclinée vers le centre du plateau ; de préférence aussi le bord périphérique intérieur est pourvu sur la totalité d'un rebord de hauteur au moins égale à l'épaisseur de la rondelle.In an exemplary embodiment of the invention, the outer peripheral edge of the end face of the plate is provided over its entire length with a flexible retaining lip having a height greater than the thickness of the washer; preferably this lip is slightly inclined towards the center of the plate; preferably also the inner peripheral edge is provided over the whole of a rim of height at least equal to the thickness of the washer.

Selon des variantes de réalisation au moins le bord périphérique extérieur ou le bord périphérique intérieur de la face extrême du plateau est muni d'au moins deux crochets aptes à retenir la rondelle après l'application de celle-ci contre la face extrême du plateau.According to alternative embodiments, at least the outer peripheral edge or the inner peripheral edge of the end face of the plate is provided with at least two hooks capable of retaining the washer after the application of the latter against the end face of the plate.

Quand le moyen de retenue de la rondelle est prévu sur l'un quelconque des deux bords périphériques de la face extrême du plateau, il est préférable de prévoir un rebord continu parallèle à l'axe du tampon dans la direction du bloc de mousse, de hauteur supérieure à l'épaisseur de la rondelle, sur la totalité de la longueur de l'autre bord périphérique.When the washer retaining means is provided on any of the two peripheral edges of the end face of the plate, it is preferable to provide a continuous rim parallel to the axis of the pad in the direction of the block of foam, height greater than the thickness of the washer, over the entire length of the other peripheral edge.

Selon une autre variante de réalisation de l'inven­tion, le moyen de retenue fait partie de la rondelle ; il est situé, de préférence, sur le bord extérieur de cette rondelle pour pouvoir s'accrocher au plateau qui fait partie du support.According to another alternative embodiment of the invention, the retaining means is part of the washer; it is preferably located on the outer edge of this washer in order to be able to hang onto the plate which is part of the support.

On donnera maintenant, uniquement à titre d'exemple, une description de plusieurs modes de réalisation de l'inven­tion. On se reportera au dessin annexé dans lequel :

Ces deux genres de manchons 2, 2′ sont connus en soi et ne sont pas directement l'objet de l'invention. Dans les deux cas, le support 1 ou 1′ a, à son extrémité opposée à sa partie extrême qui constitue le manchon 2, 2′, un plateau transversal 3 de fermeture du manchon 2, 2′ avec une face extrême 4 située dans un plan transversal à la dimension longitudinale du manchon 2, 2′. De façon connue en soi, le plateau transversal 3 est pourvu à l'inté­rieur du volume du manchon 2 ou 2′ d'un bossage central 5 qui est traversé par un canal longitudinal 6, de préférence coaxial au manchon 2, 2′. Ce canal 6 traverse aussi l'épais­seur du plateau 3 et s'ouvre dans la face extrême 4 de ce dernier. Par conséquent, ainsi qu'on le voit mieux sur les figures 5 à 7, cette face extrême 4 a un bord périphéri­que extérieur 7 et un bord périphérique intérieur 8.These two kinds of sleeves 2, 2 ′ are known per se and are not directly the subject of the invention. In both cases, the support 1 or 1 ′ has, at its end opposite to its end part which constitutes the sleeve 2, 2 ′, a transverse plate 3 for closing the sleeve 2, 2 ′ with an end face 4 located in a plane transverse to the longitudinal dimension of the sleeve 2, 2 ′. In a manner known per se, the transverse plate 3 is provided inside the volume of the sleeve 2 or 2 ′ with a central boss 5 which is traversed by a longitudinal channel 6, preferably coaxial with the sleeve 2, 2 ′. This channel 6 also crosses the thickness of the plate 3 and opens in the end face 4 of the latter. Consequently, as can be seen more clearly in FIGS. 5 to 7, this end face 4 has an outer peripheral edge 7 and an inner peripheral edge 8.

Le tampon de l'invention comprend en plus une rondelle 9 (figure 3) ayant un trou ou canal central 10 qui, après assemblage de cette rondelle avec le support 1 comme on le décrira plus loin, se trouve dans le prolonge­ment du canal 6.The pad of the invention further comprises a washer 9 (FIG. 3) having a central hole or channel 10 which, after assembly of this washer with the support 1 as will be described below, is in the extension of the channel 6.

La rondelle 9 est réalisée en matière plastique susceptible d'être sensible à l'effet d'une colle pour être fixée à une autre pièce. Une telle colle agit par attaque de la matière plastique qu'elle ramollit et qu'elle met superficiellement à l'état pâteux. Les matières plasti­ques sensibles aux colles et les colles correspondantes sont bien connues. On peut citer le polystyrène, le poly­chlorure de vinyle, le méthacrylate. Ce dernier est plus coûteux que le polychlorure de vinyle qui est lui-même plus coûteux que le polystyrène. Ce dernier est donc préféré dans le cadre de l'invention. Toutefois, une matière autre qu'une matière plastique peut servir aussi à la fabrication de la rondelle 9.The washer 9 is made of plastic material capable of being sensitive to the effect of an adhesive in order to be fixed to another part. Such an adhesive acts by attacking the plastic material which it softens and which it superficially puts in the pasty state. Plastics sensitive to adhesives and the corresponding adhesives are well known. Mention may be made of polystyrene, polyvinyl chloride, methacrylate. The latter is more expensive than polyvinyl chloride which is itself more expensive than polystyrene. The latter is therefore preferred in the context of the invention. However, a material other than a plastic material can also be used in the manufacture of the washer 9.

La rondelle 9 a deux faces principales opposées ; une première face 11 et une seconde face 12. Cette seconde face 12 est destinée à servir à la fixation d'un bloc de mousse 13, connu en soi, qui est couramment en mousse de polyuréthane ou polyester, à cellules ouvertes. La figure 4 montre un bloc de mousse 13 fixé à la rondelle 9 ; ce bloc 13 a lui-même un canal central 14 qui prolonge coaxiale­ment le canal 10 de la rondelle 9.The washer 9 has two opposite main faces; a first face 11 and a second face 12. This second face 12 is intended to be used for fixing a block of foam 13, known per se, which is commonly made of polyurethane or polyester foam, with open cells. FIG. 4 shows a block of foam 13 fixed to the washer 9; this block 13 itself has a central channel 14 which coaxially extends the channel 10 of the washer 9.

Du fait que la rondelle 9 est sensible à l'effet d'une colle appropriée, la fixation du bloc de mousse 13 à cette rondelle peut se faire à froid.Because the washer 9 is sensitive to the effect of an appropriate adhesive, the foam block 13 can be fixed to this washer when cold.

La première face 11 de la rondelle 9 est destinée à être appliquée et à être tenue appliquée contre la face extrême 4 du plateau 3 qui fait partie du support 1. Pour que la rondelle 9 soit tenue en place, l'un au moins des bords périphériques 7, 8 est muni d'un moyen de retenue. Sur la figure 5 le bord périphérique extérieur 7 est pourvu sur la totalité de sa longueur d'une lèvre souple 15 légèrement inclinée vers le milieu de la face extrême 3. Cette lèvre 15 est assez souple pour pouvoir être repoussée vers l'extérieur et permettre la mise en place de la rondelle 9 contre la face extrême 3 ; ensuite elle reprend sa forme initiale par élasticité naturelle et elle retient la rondelle 9 à laquelle est collé le bloc de mousse 13. La rondelle 9 est retenue à sa place avec un léger jeu par rapport à la face extrême 4 du plateau 3 ; elle s'applique contre cette face extrême 4 quand on appuie sur le bloc de mousse 13. Ce mode de retenue de la rondelle 9 correspond à ce qu'on appelle ici l'application de la rondelle 9 contre la face extrême 4.The first face 11 of the washer 9 is intended to be applied and to be held applied against the end face 4 of the plate 3 which is part of the support 1. In order for the washer 9 to be held in place, at least one of the edges peripherals 7, 8 is provided with a retaining means. In Figure 5 the outer peripheral edge 7 is provided over its entire length with a flexible lip 15 slightly inclined towards the middle of the end face 3. This lip 15 is flexible enough to be able to be pushed outwards and allow placing the washer 9 against the end face 3; then it returns to its initial shape by natural elasticity and it retains the washer 9 to which the foam block 13 is glued. The washer 9 is retained in its place with a slight clearance relative to the end face 4 of the plate 3; it is applied against this end face 4 when the foam block 13 is pressed 13. This method of retaining the washer 9 corresponds to what is called here the application of the washer 9 against the end face 4.

Sur la figure 6 le bord périphérique intérieur 8 de la face extrême 4 est pourvu de plusieurs crochets 16 qui s'étendent dans le sens longitudinal du manchon 2 ; ces crochets sont espacés le long du bord 8 et ils ont chacun une face latérale 17 en oblique suivie d'une face transversale 18 substantiellement parallèle à la face extrême 4. Quand on pousse la rondelle 9 contre les faces obliques latérales 17 en direction de la face extrême 4, les crochets 16 s'inclinent vers l'axe du canal 6 et ils reprennent leur position initiale après le passage de la rondelle 9, la distance entre les faces transversales 18 et la face extrême 4 étant, bien entendu, légèrement supé­rieure à l'épaisseur de la rondelle 4 et le canal 10 de celle-ci ayant une dimension appropriée.In Figure 6 the inner peripheral edge 8 of the end face 4 is provided with several hooks 16 which extend in the longitudinal direction of the sleeve 2; these hooks are spaced along the edge 8 and they each have a lateral face 17 obliquely followed by a transverse face 18 substantially parallel to the end face 4. When the washer 9 is pushed against the lateral oblique faces 17 towards the end face 4, the hooks 16 tilt towards the axis of the channel 6 and they return to their initial position after the passage of the washer 9, the distance between the transverse faces 18 and the end face 4 being, of course, slightly greater to the thickness of the washer 4 and the channel 10 thereof having an appropriate dimension.

Sur la figure 7, le bord périphérique extérieur 7 est pourvu d'une jupe continue 19 parallèle à l'axe géomé­trique du canal 6 et munie à son extrémité libre d'un crochet 16′ continu s'étendant sur tout le périmètre de cette jupe 19. Ce crochet 16′ est analogue aux crochets 16 mais il est dirigé vers l'intérieur. Cette jupe 19 s'évase vers l'extérieur quand on pousse la rondelle 9 vers la face extrême 4 du plateau 3 puis elle reprend sa position et retient la rondelle.In Figure 7, the outer peripheral edge 7 is provided with a continuous skirt 19 parallel to the geometric axis of the channel 6 and provided at its free end with a continuous hook 16 ′ extending over the entire perimeter of this skirt 19. This hook 16 ′ is similar to the hooks 16 but it is directed inward. This skirt 19 flares outwards when the washer 9 is pushed towards the end face 4 of the plate 3 then it returns to its position and retains the washer.

Il serait possible, mais sans avantage particulier, de prévoir un moyen de retenue à la fois sur le bord péri­phérique extérieur 7 et sur le bord périphérique intérieur 8.It would be possible, but without any particular advantage, to provide a retaining means both on the outer peripheral edge 7 and on the inner peripheral edge 8.

Au contraire, quand un bord quelconque 7 ou 8 est pourvu d'un moyen de retenue, il est souhaitable de prévoir sur la totalité de l'autre bord, intérieur 8 (figure 5) ou extérieur 7 (figure 6) un rebord extérieur 20 (figure 6) ou intérieur 20′ (figure 5) s'étendant parallélement à l'axe géométrique du bloc de mousse 13 sur une longueur légèrement supérieure à l'épaisseur de la rondelle 9. Le rebord extérieur 20 contient la rondelle 9 et la mousse 13 et donne un aspect plus net au tampon. Le rebord intérieur 20′ protège le canal 6 contre l'entrée de la colle dans ce dernier quand on effectue le collage du bloc de mousse 13 à la rondelle 9 après avoir mis celle-ci à sa place contre la face extrême 4.On the contrary, when any edge 7 or 8 is provided with a retaining means, it is desirable to provide on the entire other edge, inside 8 (figure 5) or outside 7 (figure 6) an outside edge 20 (Figure 6) or interior 20 ′ (Figure 5) extending parallel to the geometric axis of the foam block 13 over a length slightly greater than the thickness of the washer 9. The outer flange 20 contains the washer 9 and the foam 13 and gives a clearer appearance to the tampon. The inner rim 20 ′ protects the channel 6 against the entry of the adhesive into the latter when the foam block 13 is bonded to the washer 9 after having put the latter in its place against the end face 4.

Il est possible aussi de prévoir le moyen de retenue non pas sur un bord périphérique 7, 8 de la face extrême 4 mais sur un des bords périphériques correspondants 7′, 8′ de la rondelle 9 ; la figure 8 montre l'exemple d'une rondelle 9 dont le bord périphérique extérieur 7′ est muni sur une partie au moins de sa longueur d'un moyen de retenue constitué par une lèvre d'accrochage 15′ analogue à la lèvre 15 mais dirigée en sens inverse par rapport au bloc de mousse 13 pour pouvoir se resserrer ou s'accrocher en arrière du plateau 3 qu'elle contient. Dans ce cas, la rondelle 9 elle-même peut être munie à l'opposé de la lèvre 15′ d'un rebord 20˝ jouant le même rôle que le rebord 20. Cette simple inversion de la disposition du moyen de retenue, qui peut être appliquée aussi au bord périmétrique intérieur 8′ de la rondelle 9 sous forme de crochets s'enga­geant dans le canal 6, ne sort pas du cadre de l'invention.It is also possible to provide the retaining means not on a peripheral edge 7, 8 of the end face 4 but on one of the corresponding peripheral edges 7 ′, 8 ′ of the washer 9; FIG. 8 shows the example of a washer 9 whose outer peripheral edge 7 ′ is provided on at least part of its length with a retaining means constituted by a hooking lip 15 ′ similar to lip 15 but directed in the opposite direction relative to the foam block 13 in order to be able to tighten or hang behind the plate 3 which it contains. In this case, the washer 9 itself can be provided opposite the lip 15 ′ with a flange 20˝ playing the same role as the flange 20. This simple reversal of the arrangement of the retaining means, which can also be applied to the inner perimeter edge 8 ′ of the washer 9 in the form of hooks engaging in the channel 6, does not depart from the scope of the invention.

La fixation par collage à froid du bloc de mousse 13 à la rondelle 9 peut se faire avant la mise en place de cette rondelle dans le support 1 comme le montre la figure 4, ou après la mise en place de la rondelle dans le support 1.The fixing by cold gluing of the foam block 13 to the washer 9 can be done before the installation of this washer in the support 1 as shown in FIG. 4, or after the installation of the washer in the support 1 .

On notera que le tampon de l'invention est réalisa­ble à des dimensions très diverses et avec des configurations géométriques également très diverses du bloc de mousse.It will be noted that the pad of the invention can be produced in very diverse dimensions and with also very diverse geometric configurations of the foam block.

La figure 9 montre un tampon analogue à celui de la figure 1 mais représenté avec une soupape intérieure qui s'oppose à la sortie indésirable du produit à étaler. Selon ce mode de réalisation, le moyen de retenue est prévu sur le bord extérieur 7 du plateau 3. Ce moyen de retenue est une jupe 19 s'étendant dans la même direction que le bloc de mousse 13 et conformée en crochet continu 16′ à son extrémité libre, sur la totalité de sa longueur, de manière analogue à celle de la figure 7. La face transversale de retenue 18 de ce crochet est, comme dans les exemples de crochets décrits plus haut, parallèle à la face extrême 4 à une distance de celle-ci supérieure d'une valeur très faible à l'épaisseur de la rondelle 9.Figure 9 shows a pad similar to that of Figure 1 but shown with an inner valve which prevents the unwanted outlet of the product to spread. According to this embodiment, the retaining means is provided on the outer edge 7 of the plate 3. This retaining means is a skirt 19 extending in the same direction as the foam block 13 and shaped as a continuous hook 16 ′ to its free end, over its entire length, similar to that of FIG. 7. The transverse retaining face 18 of this hook is, as in the examples of hooks described above, parallel to the end face 4 at a distance from the latter of a very small value greater than the thickness of the washer 9.

Cette figure 9 montre que le canal 6 du bossage 5 contient une soupape 21 ayant une tête 22 et une tige 23. L'entrée du canal 6 sert de siège à la tête 22 avec laquelle fait corps un ressort de rappel 24 à trois éléments en spirale. Ces derniers font corps aussi avec un disque 25 qui est introduit dans le manchon souple 2. Ce disque 25 est retenu à sa position par des petits ergots 26 qui sont prévus sur la face intérieure du manchon 2. La tige 23 de la soupape 21 s'étend à travers le canal 10 de la rondelle 9 et pénêtre à l'intérieur du bloc de mousse 13. Ce dernier est dépourvu de canal central. Le rôle de ce canal central à travers le bloc de mousse est joué par le canal 10 prévu dans la rondelle 9. Le diamètre de ce canal 10 est fixé en fonction du débit désiré du produit à étaler et de la viscosité de ce dernier. Comme le bloc de mousse 13 n'est pas traversé par un canal, et comme il est ceinturé à sa base par la jupe continue 19, il est plus résistant aux efforts qu'il doit supporter pendant l'étalement du produit.This FIG. 9 shows that the channel 6 of the boss 5 contains a valve 21 having a head 22 and a rod 23. The inlet of the channel 6 serves as a seat for the head 22 with which is formed a return spring 24 with three elements in spiral. The latter also form a body 25 with a disc 25 which is introduced into the flexible sleeve 2. This disc 25 is retained in its position by small pins 26 which are provided on the inner face of the sleeve 2. The rod 23 of the valve 21 s 'extends through the channel 10 of the washer 9 and penetrates inside the block of foam 13. The latter has no central channel. The role of this central channel through the foam block is played by the channel 10 provided in the washer 9. The diameter of this channel 10 is fixed according to the desired flow rate of the product to be spread and the viscosity of the latter. As the foam block 13 is not traversed by a channel, and since it is surrounded at its base by the continuous skirt 19, it is more resistant to the forces that it must withstand during the spreading of the product.
