Description

La présente invention concerne un écouvillon de nettoyage d'un récipient, notamment d'une cuve de biberon, selon la revendication 1.The present invention relates to a cleaning swab of a container, especially a bottle tank, according to claim 1.

L'invention s'applique tout particulièrement, mais non exclusivement, aux récipients possédant une ouverture de dimensions réduites par rapport au corps du récipient.The invention is particularly, but not exclusively, applicable to containers having an opening of reduced dimensions relative to the body of the container.

De façon schématique, un biberon présente une cuve généralement transparente sur laquelle est retenue une tétine.In a schematic way, a bottle has a generally transparent tank on which is retained a nipple.

Il est nécessaire d'effectuer un nettoyage de la cuve après chaque utilisation. En effet, il peut se former dans la cuve des dépôts, notamment de lait ou de bouillie, qui nécessitent une action mécanique à l'intérieur de la cuve pour décoller ces dépôts.It is necessary to clean the tank after each use. Indeed, it can be formed in the tank deposits, including milk or slurry, which require a mechanical action inside the tank to take off these deposits.

La difficulté du nettoyage d'une cuve de biberon tient à la géométrie générale en forme de cylindre avec un accès restreint par une ouverture circulaire de diamètre inférieur à celui de la cuve.The difficulty of cleaning a bottle tank is the general geometry cylinder-shaped with restricted access by a circular opening of smaller diameter than that of the tank.

Le nettoyage de la cuve d'un biberon se fait généralement à l'aide d'un écouvillon.Cleaning the tank of a bottle is usually done with a swab.

Traditionnellement, un écouvillon comprend un manche et une partie formant brosse. La partie formant brosse est elle-même constituée d'une torsade de fils métalliques de laquelle partent radialement des poils en hélice. Ces poils sont constitués de fibres synthétiques de type polyamide, polypropylène ou similaire.Traditionally, a swab includes a handle and a brush portion. The brush portion is itself made of a twist of metal son which radially leave helical hairs. These bristles are made of synthetic fibers of the polyamide, polypropylene or similar type.

On peut également avoir recours à une brosse pour assurer le nettoyage d'une cuve de biberon, c'est-à-dire un ustensile généralement en plastique comprenant un manche de préhension associé à une tête de nettoyage constituée d'une embase dans laquelle sont implantées des touffes de poils.It is also possible to use a brush for cleaning a bottle-feeding tank, that is to say a generally plastic utensil comprising a grip handle associated with a cleaning head consisting of a base in which are implanted tufts of hair.

Pour que ces touffes de poils soient correctement fixées, le volume de l'embase doit être proportionné en fonction du nombre et du diamètre des touffes.For these tufts of hair to be properly fixed, the volume of the base must be proportioned according to the number and the diameter of the tufts.

Pour le nettoyage d'une cuve de biberon, on trouve principalement deux types de brosses :

  • une brosse de type boule comportant une embase sur laquelle sont disposées des touffes de poils de façon radiale ainsi qu'en extrémité. Pour permettre le passage de la brosse dans le col du biberon, le volume de l'embase ne peut être que faible, limitant le nombre de touffes, ce qui rend le nettoyage peu efficace.
  • une brosse de type balayette sur laquelle les touffes de poils sont réparties sur une seule face de l'embase et parfois en extrémité. Le volume de l'embase doit être, là aussi, en adéquation avec le nombre de touffes de la brosse afin de passer dans le col du biberon. Cette brosse est peu efficace car elle ne possède des touffes que sur une seule face de l'embase. De plus, la face de l'embase opposée aux touffes de poils risque de rayer la surface interne du biberon.
For the cleaning of a bottle tank, there are mainly two types of brushes:
  • a ball-type brush having a base on which tufts of bristles are arranged radially and at the end. To allow the passage of the brush in the neck of the bottle, the volume of the base can only be weak, limiting the number of tufts, which makes the cleaning inefficient.
  • a brush-type brush on which the tufts of bristles are distributed on one side of the base and sometimes at the end. The volume of the base must be, again, in line with the number of tufts of the brush to pass into the neck of the bottle. This brush is inefficient because it has tufts on one side of the base. In addition, the face of the base opposite the tufts of hair may scratch the inner surface of the bottle.

Il apparaît ainsi que, quel que soit l'ustensile de nettoyage utilisé dans une cuve de biberon, celle-ci peut être imparfaitement nettoyée, voire également rayée.It appears that, whatever the cleaning device used in a bottle tank, it can be imperfectly cleaned, or even scratched.

De plus, les écouvillons ou brosses actuels sont encombrants du fait de leurs poils ou touffes de poils, ce qui rend leur stockage problématique. Cela s'avère être un problème en utilisation nomade puisque l'écouvillon ou la brosse sont transportés dans un sac avec d'autres ustensiles dont les contacts répétés finissent par aplatir les poils, ce qui leur ôte toute efficacité.In addition, current swabs or brushes are bulky because of their hairs or tufts of hair, which makes their storage problematic. This proves to be a problem in mobile use since the swab or the brush are transported in a bag with other utensils whose repeated contacts eventually flatten the hair, which robs them of any effectiveness.

Le document US 2002/0112301 décrit une brosse pour biberon qui comporte d'une part d'un bouchon coopérant avec le col du biberon et d'autre part d'une partie munie de poils qui se déforme lorsqu'elle est introduite dans le biberon. Le lavage de l'intérieur du biberon s'effectue par la rotation de la brosse, au moyen du bouchon. L'inconvénient majeur de cette brosse est qu'elle est conçue pour une géométrie et des dimensions particulières de biberon. En d'autres termes, il est nécessaire de prévoir une brosse adaptée à chaque type ou dimension de biberon.The document US 2002/0112301 discloses a bottle brush which comprises on the one hand a plug cooperating with the neck of the bottle and on the other hand a portion provided with bristles which deforms when it is introduced into the bottle. Washing the inside of the bottle is done by rotating the brush, using the cap. The major disadvantage of this brush is that it is designed for a specific geometry and bottle dimensions. In other words, it is necessary to provide a brush adapted to each type or size of bottle.

Les documents US 1 389 957 et US 2 228 062 décrivent des brosses pour nettoyer un radiateur.The documents US 1,389,957 and US 2,228,062 describe brushes for cleaning a radiator.

Dans ce contexte technique, un but de l'invention est de proposer un ustensile de nettoyage, notamment de cuve de biberon, qui offre une meilleure efficacité que les écouvillons et brosses connus et qui puisse être d'un stockage aisé.In this technical context, an object of the invention is to provide a cleaning utensil, including a bottle-feeding tank, which offers greater efficiency than known swabs and brushes and which can be easily stored.

Ainsi, l'invention offre un écouvillon original qui possède des éléments de nettoyage s'inscrivant dans un volume de faible épaisseur, globalement plat voire plan. On a donc un unique ensemble globalement plat d'éléments de nettoyage.Thus, the invention provides an original swab that has cleaning elements in a thin volume, generally flat or even planar. So we have a single globally flat set of cleaning elements.

Par « plat » on entend que l'ensemble d'éléments de nettoyage n'est pas nécessairement parfaitement plan mais possède un plan moyen généralement confondu avec le plan moyen de l'embase. En outre, selon une réalisation avantageuse, l'ensemble des éléments de nettoyage présente la forme générale d'un volume de faible épaisseur qui est sensiblement plan, c'est-à-dire non courbé, et de préférence sensiblement confondu avec le plan moyen de l'embase.By "flat" is meant that the set of cleaning elements is not necessarily perfectly flat but has an average plane generally coincides with the average plane of the base. In addition, according to an advantageous embodiment, the set of cleaning elements has the general shape of a thin volume which is substantially flat, that is to say not curved, and preferably substantially coincides with the average plane. of the base.

Par « à l'opposé l'une de l'autre par rapport à l'embase », on entend que les branches de la zone de fixation en U sont situées de part et d'autre de l'embase, et sont disposées « dos à dos », c'est-à-dire sont orientées vers des sens différents et non tournées dans la même direction.By "opposite to each other relative to the base" is meant that the branches of the U-shaped fastening area are located on either side of the base, and are arranged " back to back ", that is to say are oriented towards different directions and not turned in the same direction.

On peut par exemple prévoir que les éléments de nettoyage fixés au niveau d'une branche de la zone de fixation en U s'étendent depuis cette branche globalement dans un sens opposé au sens dans lequel s'étendent les éléments de nettoyage qui sont fixés au niveau de l'autre branche de la zone de fixation en U.For example, it is possible to provide that the cleaning elements fastened at a branch of the U-shaped fastening area extend from this branch generally in a direction opposite to the direction in which the cleaning elements which are attached to the level of the other branch of the U-shaped fastening area.

On notera que les éléments de nettoyage ne couvrent pas nécessairement de façon continue l'ensemble de la surface de la zone de fixation en U, mais peuvent être disposés de façon discontinue - par exemple en touffes de poils - le long de toute cette surface.Note that the cleaning elements do not necessarily cover continuously the entire surface of the U-shaped fastening area, but may be arranged discontinuously - for example in tuft of hair - along the entire surface.

Cet écouvillon est donc d'un encombrement très inférieur à celui des écouvillons traditionnels, ce qui lui permet d'être stocké plus facilement. En outre, l'écouvillon selon l'invention permet un meilleur nettoyage car les éléments de nettoyage sont concentrés dans un volume plat. Cette disposition a l'avantage de concilier la facilité d'introduction dans la cuve d'un biberon et la faculté de décoller d'éventuels résidus qui adhèrent à la surface interne de la cuve. Un autre avantage important de l'invention est que l'écouvillon est universel, c'est-à-dire qu'il peut être utilisé avec tout type et toutes dimensions de biberons.This swab is therefore of a much smaller footprint than traditional swabs, which allows it to be stored more easily. In addition, the swab according to the invention allows better cleaning because the cleaning elements are concentrated in a flat volume. This arrangement has the advantage of reconciling the ease of introduction into the tank of a bottle and the ability to take off any residues that adhere to the inner surface of the tank. Another important advantage of the invention is that the swab is universal, that is, it can be used with any type and size of baby bottles.

L'embase peut être bi injectée avec le manche. En variante, l'embase et le manche sont deux pièces séparées pouvant être assemblées l'une à l'autre, éventuellement de façon démontable. Le fait de prévoir l'écouvillon en deux pièces séparées facilite le transport et le stockage et permet de remplacer la tête de nettoyage tout en conservant le même manche.The base can be bi injected with the handle. Alternatively, the base and the handle are two separate parts that can be assembled to one another, possibly removably. Providing the swab in two separate parts facilitates transport and storage and allows replacement of the cleaning head while maintaining the same handle.

De préférence, l'embase présente une forme allongée de façon à faciliter l'introduction de l'embase dans le biberon et à lui permettre d'atteindre le fond du biberon.Preferably, the base has an elongate shape so as to facilitate the introduction of the base in the bottle and to allow it to reach the bottom of the bottle.

Selon une réalisation possible, l'embase s'étend selon un axe longitudinal sensiblement rectiligne. Dans cette réalisation, l'embase peut présenter un profil plan, et on peut prévoir en outre que les éléments de nettoyage soient disposés sensiblement dans le plan de l'embase.According to one possible embodiment, the base extends along a substantially rectilinear longitudinal axis. In this embodiment, the base can have a plane profile, and it can further be provided that the cleaning elements are arranged substantially in the plane of the base.

Selon une autre réalisation, l'embase s'étend selon une direction longitudinale courbe ou formant une ligne brisée. Dans cette réalisation, les branches du U formant la zone de fixation suivent la géométrie de l'embase, c'est-à-dire sont également courbes (par exemple en arc de cercle ou en S) ou forment également une ligne brisée. L'embase peut présenter un profil gauche, par exemple de faible épaisseur.In another embodiment, the base extends in a longitudinal direction curved or forming a broken line. In this embodiment, the branches of the U forming the fixing zone follow the geometry of the base, that is to say are also curved (for example in an arc or S) or also form a broken line. The base may have a left profile, for example of small thickness.

On peut prévoir que l'embase présente une forme aplatie de section transversale sensiblement rectangulaire, les éléments de nettoyage étant fixés uniquement sur deux faces périphériques opposées de l'embase et sur la paroi d'extrémité de l'embase. Par exemple, les éléments de nettoyage peuvent être fixés sur les faces périphériques correspondant aux petits côtés du rectangle. L'homme du métier comprendra que, de façon similaire, l'embase pourrait être de toute autre forme aplatie, notamment, mais non exclusivement, ovale.It can be provided that the base has a flattened shape of substantially rectangular cross section, the cleaning elements being fixed only on two opposite peripheral faces of the base and on the end wall of the base. For example, the cleaning elements can be fixed on the peripheral faces corresponding to the short sides of the rectangle. Those skilled in the art will understand that, similarly, the base could be any other flattened form, including, but not exclusively, oval.

Selon une réalisation possible, les éléments de nettoyage s'étendent depuis l'embase en étant orientés par rapport à la perpendiculaire à la zone de liaison d'un angle compris entre - 30° et + 30°. On peut par exemple prévoir que cet angle soit non nul.According to one possible embodiment, the cleaning elements extend from the base being oriented relative to the perpendicular to the connection zone by an angle of between -30 ° and + 30 °. For example, this angle may be non-zero.

En variante, les éléments de nettoyage s'étendent depuis l'embase sensiblement perpendiculairement à la zone de liaison. Les éléments de nettoyage peuvent alors former un ensemble plat, voire plan, de faible épaisseur.In a variant, the cleaning elements extend from the base substantially perpendicularly to the connection zone. The cleaning elements can then form a flat or even flat, thin.

Typiquement, les éléments de nettoyage appartiennent au groupe comprenant : les poils agencés en touffes séparés ou en nappe, les picots souples, les lamelles souples. La configuration en une nappe de poils sensiblement continue permet d'envisager un process de fabrication particulièrement rapide de l'écouvillon.Typically, the cleaning elements belong to the group comprising: the bristles arranged in separate tufts or in sheets, the flexible pins, the flexible lamellae. The configuration into a substantially continuous layer of bristles makes it possible to envisage a particularly rapid process for manufacturing the swab.

Selon différentes réalisations possibles, les éléments de nettoyage comprennent des poils agencés en au moins une nappe fixée à l'embase par soudage, collage ou emboîture mécanique ; et/ou les éléments de nettoyage comprennent des poils agencés en touffes séparées, réparties en un ou plusieurs rangs.According to various possible embodiments, the cleaning elements comprise bristles arranged in at least one ply fixed to the base by welding, gluing or mechanical socket; and / or the cleaning elements comprise bristles arranged in separate tufts, distributed in one or more rows.

L'embase peut comprendre au moins une gorge périphérique formant la zone de liaison entre les éléments de nettoyage et l'embase, au moins une nappe de poils étant engagée dans la ou chaque gorge.The base may comprise at least one peripheral groove forming the connection zone between the cleaning elements and the base, at least one layer of bristles being engaged in the or each groove.

L'embase peut être réalisée dans un matériau souple permettant à l'embase de prendre une configuration déformée - par exemple hélicoïdale - lors de l'insertion dans la cuve d'un biberon. Cette forme de réalisation s'avère particulièrement avantageuse puisqu'elle prévoit une flexibilité de l'embase pour plus d'efficacité de nettoyage. A titre d'exemple, le matériau constitutif de l'embase peut présenter une souplesse comprise entre 50 et 80 Shore A.The base can be made of a flexible material allowing the base to take a deformed configuration - for example helical - when inserting into the tank of a bottle. This embodiment is particularly advantageous since it provides a flexibility of the base for more cleaning efficiency. By way of example, the material constituting the base can have a flexibility of between 50 and 80 Shore A.

L'embase peut en outre présenter une partie arrondie à son extrémité opposée à celle connectée au manche, de manière à assurer le nettoyage du fond de la cuve.The base may further have a rounded portion at its end opposite to that connected to the handle, so as to ensure the cleaning of the bottom of the tank.

Il peut par ailleurs être prévu que l'embase présente une échancrure centrale. Cette disposition est plus particulièrement avantageuse dans le cas de figure où l'embase est flexible puisque l'échancrure contribue à la flexibilité de l'embase.It may also be provided that the base has a central notch. This arrangement is more particularly advantageous in the case where the base is flexible since the notch contributes to the flexibility of the base.

Pour sa bonne compréhension, l'invention est décrite en référence au dessin schématique ci annexé représentant, à titre d'exemples non limitatifs, plusieurs modes de réalisation d'un écouvillon selon celle-ci.

For a good understanding, the invention is described with reference to the attached schematic drawing showing, by way of non-limiting examples, several embodiments of a swab according thereto.
  • The Figures 1 to 3 show a swab according to a first embodiment, respectively in side view, in front view, and in top view;
  • The Figures 4 to 6 show the swab defined in the preceding figures in the case of torsion, respectively in side view, in front view and in top view;

  • The Figures 15 to 17 show a swab according to a fourth embodiment, respectively in front view, in side view, and in top view.

En se reportant tout d'abord aux figures 1 et 2, on peut voir que l'écouvillon 1 selon l'invention présente essentiellement deux parties à savoir, un manche 2 de préhension auquel est accolée une tête 3 de nettoyage.Referring first to Figures 1 and 2 it can be seen that the swab 1 according to the invention essentially has two parts, namely a handle 2 gripping which is joined a cleaning head 3.

Le manche 2 de préhension est représenté sur les figures par un élément cylindrique. D'autres formes d'exécution du manche 2 sont bien entendu envisagées notamment des formes de réalisation permettant une meilleure ergonomie.The handle 2 is shown in the figures by a cylindrical member. Other embodiments of the handle 2 are of course envisaged including embodiments for better ergonomics.

L'écouvillon 1 selon ce premier mode de réalisation possède une tête 3 de nettoyage tout à fait originale puisque celle-ci est essentiellement plane.The swab 1 according to this first embodiment has a cleaning head 3 completely original since it is essentially flat.

En effet, la tête 3 de nettoyage, comme on peut la voir plus précisément aux figures 7 à 9, possède une embase 5 qui est fixée sur le manche 2, cette embase 5 recevant une nappe 7 continue plane de poils.Indeed, the cleaning head 3, as can be seen more precisely at Figures 7 to 9 , has a base 5 which is fixed on the handle 2, this base 5 receiving a continuous web 7 of pile.

Par poils, il faut entendre au sens du présent document des brins de matière synthétique souple de type polyamide, polypropylène, pvc ou polyester dont le diamètre peut varier entre 0,10 et 0,50 millimètre. Avec des poils fins d'un diamètre de l'ordre de 0,20 mm, les risques de rayer le récipient sont considérablement réduits.For the purposes of this document, "hair" is intended to mean strands of flexible synthetic material of the polyamide, polypropylene, pvc or polyester type whose diameter may vary between 0.10 and 0.50 millimeters. With some fine hairs with a diameter of about 0.20 mm, the risk of scratching the container is greatly reduced.

De façon plus générale, d'autres éléments de nettoyage que des poils peuvent être utilisés, comme des picots souples ou des lamelles souples.More generally, other cleaning elements than bristles may be used, such as soft nubs or flexible sipes.

Dans l'exemple illustré sur les figures, l'embase 5 possède une forme générale prismatique allongée dont les côtés sont convergents en direction du manche 2 de préhension de l'écouvillon. A son extrémité opposée à celle fixée au manche 2, l'embase 5 présente une extrémité arrondie 10. Dans la réalisation illustrée, l'embase 5 possède une section transversale sensiblement rectangulaire et présente donc une paroi périphérique comportant deux petites faces et deux grandes faces.In the example illustrated in the figures, the base 5 has a generally elongated prismatic shape, the sides of which are convergent in the direction of the handle 2 for gripping the swab. At its end opposite that fixed to the handle 2, the base 5 has a rounded end 10. In the illustrated embodiment, the base 5 has a substantially rectangular cross section and therefore has a peripheral wall having two small faces and two large faces .

La nappe 7 de poils s'étend ici sensiblement perpendiculairement à la face de l'embase 5 à laquelle elle est fixée.The ply 7 of bristles extends here substantially perpendicular to the face of the base 5 to which it is attached.

On note également que l'embase 5 peut comprendre une échancrure 8 centrale.It is also noted that the base 5 may comprise a central notch 8.

Si l'on se réfère par exemple aux figures 7 et 9, il apparaît que l'embase 5 présente sur sa périphérie une gorge 9 dans laquelle est insérée la nappe 7 de poils. La nappe 7 de poils peut être fixée sur l'embase 5 par différents modes de fixation tels que collage, soudage, emboîtement mécanique.For example, if we refer to Figures 7 and 9 , it appears that the base 5 has on its periphery a groove 9 in which is inserted the ply 7 of bristles. The ply 7 of bristles can be fixed on the base 5 by different modes of attachment such as gluing, welding, mechanical interlocking.

Le fond de la gorge 9 forme une zone de fixation entre les poils et l'embase 5. Cette zone de fixation présente ainsi la forme d'un U ayant deux branches s'étendant sur les petites faces de l'embase 5, sensiblement selon l'axe 4 longitudinal de l'embase 5, et une partie de jonction reliant les deux branches, s'étendant sur l'extrémité arrondie 10 de l'embase 5.The bottom of the groove 9 forms a zone of attachment between the bristles and the base 5. This fastening zone thus has the shape of a U having two branches extending on the small faces of the base 5, substantially according to the longitudinal axis 4 of the base 5, and a connecting portion connecting the two branches, extending on the rounded end 10 of the base 5.

On voit que l'écouvillon selon ce premier mode de réalisation de l'invention possède donc une tête 3 de nettoyage plan, ce qui la distingue des écouvillons classiques dans lesquels les poils sont distribués de manière radiale autour généralement d'un axe en fils de fer torsadés.It can be seen that the swab according to this first embodiment of the invention thus has a planar cleaning head 3, which distinguishes it from conventional swabs in which the bristles are distributed radially around generally a spindle axis. twisted iron.

Dans l'exemple représenté sur les figures, la nappe 7 de poils présente la forme générale d'un U.In the example shown in the figures, the ply 7 of bristles has the general shape of a U.

On peut préciser que la nappe 7 de poils est elle-même constituée d'un profilé de poils juxtaposés et reliés entre eux au niveau d'une base commune. Ce type de profilé peut être disponible sur de grandes longueurs qui sont coupées à la dimension de l'embase 5 puis sont fixées à celle-ci selon l'une des techniques précitées.It may be noted that the ply 7 of bristles is itself constituted by a section of bristles juxtaposed and connected together at a common base. This type of profile can be available over long lengths which are cut to the size of the base 5 and are attached thereto according to one of the aforementioned techniques.

Une autre disposition originale de l'écouvillon selon l'invention réside dans le fait que l'embase 5 peut être réalisée dans un matériau souple. Cette disposition s'avère tout à fait intéressante dans la mesure où elle autorise une déformation de l'embase 5, comme on le verra plus tard.Another original arrangement of the swab according to the invention lies in the fact that the base 5 can be made of a flexible material. This arrangement is quite interesting insofar as it allows a deformation of the base 5, as will be seen later.

Dans le cas où l'embase 5 est réalisée dans une matière souple, qui est donc distincte de la matière plastique dans laquelle le manche 2 de préhension est réalisé, il peut être prévu que le manche 2 de préhension et l'embase 5 de l'écouvillon soient réalisés dans une opération d'injection bi matière.In the case where the base 5 is made of a flexible material, which is therefore distinct from the plastic in which the handle 2 is formed, it can be provided that the handle 2 and the gripping base 5 of the swab are made in a bi-material injection operation.

A l'usage, lorsque l'écouvillon est engagé dans la cuve d'un biberon, il a la faculté de prendre une configuration déformée, par exemple sensiblement hélicoïdale, afin que les poils viennent en contact avec toutes les surfaces intérieures de la cuve, en particulier, les zones difficiles à nettoyer telles que les zones concaves, convexes et les coins entre le fond de la cuve et la paroi cylindrique. Ainsi, il est possible de décoller tout résidu de matière.In use, when the swab is engaged in the tank of a bottle, it has the ability to take a deformed configuration, for example substantially helical, so that the bristles come into contact with all the inner surfaces of the tank, in particular, areas difficult to clean such as concave areas, convex and the corners between the bottom of the tank and the cylindrical wall. Thus, it is possible to take off any residue of material.

Les figures 4 à 6 montrent ainsi la faculté de la tête 3 de nettoyage de se déformer autour de son axe longitudinal 4. Le fait que l'embase 5 est dotée d'une échancrure 8 facilite la mise en torsion de la tête 3 de nettoyage et améliore la souplesse de l'écouvillon 1.The Figures 4 to 6 thus show the ability of the cleaning head 3 to deform around its longitudinal axis 4. The fact that the base 5 is provided with a notch 8 facilitates the twisting of the cleaning head 3 and improves the flexibility of the swab 1.

Les figures 10 à 12 montrent un deuxième mode de réalisation de l'invention dans lequel les poils sont répartis sur deux rangs de touffes 11 en quinconce. La forme générale de l'embase et de l'ensemble des poils est par ailleurs similaire au premier mode de réalisation. En particulier, les touffes 11 de poils sont sensiblement perpendiculaires à la face de l'embase 5 depuis laquelle elles s'étendent.The Figures 10 to 12 show a second embodiment of the invention wherein the bristles are distributed in two rows of tufts 11 staggered. The general shape of the base and the set of bristles is also similar to the first embodiment. In particular, the tufts 11 of bristles are substantially perpendicular to the face of the base 5 from which they extend.

Ce mode de réalisation de l'invention permet de conserver la planéité de l'écouvillon 1 et donc l'avantage qui en découle en termes de stockage.This embodiment of the invention makes it possible to maintain the flatness of the swab 1 and thus the resulting benefit in terms of storage.

Dans ce mode de réalisation, le décollement des résidus à l'intérieur de la cuve du biberon est réalisé par la flexion des touffes 11 de poils elles-mêmes.In this embodiment, the detachment of the residues inside the bottle of the tank is achieved by bending the tufts 11 of hair themselves.

On se rapporte à présent aux figures 13 et 14 qui illustrent un troisième mode de réalisation de l'invention.We are now talking about Figures 13 and 14 which illustrate a third embodiment of the invention.

L'écouvillon 1 est sensiblement identique à celui décrit en référence aux figures 1 à 9 à l'exception du fait que l'embase 5 n'est pas plane mais gauche.The swab 1 is substantially identical to that described with reference to Figures 1 to 9 with the exception that the base 5 is not flat but left.

L'embase 5 s'étend ainsi dans le prolongement du manche 2 selon une direction longitudinale 6 courbe. La zone de fixation de la nappe 7 de poils sur l'embase forme donc un U gauche, et la nappe 7 de poils suit la forme générale de l'embase 5, en conservant la forme générale d'un volume plat de faible épaisseur. L'embase 5 présente un plan moyen P, qui est également le plan moyen de la nappe 7 de poils.The base 5 thus extends in the extension of the handle 2 in a longitudinal direction 6 curve. The area of attachment of the ply 7 of bristles on the base thus forms a left U, and the ply 7 of bristles follows the general shape of the base 5, retaining the general shape of a thin flat volume. The base 5 has an average plane P, which is also the average plane of the ply 7 of bristles.

Enfin, on décrit un quatrième mode de réalisation de l'invention illustré sur les figures 15 à 17.Finally, there is described a fourth embodiment of the invention illustrated on the Figures 15 to 17 .

L'écouvillon 1 est globalement identique à celui illustré sur les figures 10 à 12, à l'exception du fait que les touffes 11 de poils sont ici inclinées par rapport à la perpendiculaire à la face de l'embase 5 où ces poils sont fixés. Cette inclinaison peut être comprise entre - 30° et + 30°.The swab 1 is globally identical to that illustrated on the Figures 10 to 12 , except that the tufts 11 of bristles are here inclined relative to the perpendicular to the face of the base 5 where these bristles are fixed. This inclination can be between -30 ° and + 30 °.

En variante, les touffes 11 inclinées de poils pourraient être remplacées par des nappes inclinées de poils. Une ou plusieurs nappes peuvent ainsi être fixées dans une gorge de l'embase 5, l'embase pouvant comporter plusieurs gorges. L'inclinaison d'une nappe est par exemple obtenue par l'inclinaison du fond de la gorge sur lequel la nappe vient se fixer.Alternatively, the tilts 11 inclined bristles could be replaced by inclined plies of bristles. One or more layers may thus be fixed in a groove of the base 5, the base may include several grooves. The inclination of a sheet is for example obtained by the inclination of the bottom of the groove on which the sheet is fixed.

Il est à préciser que, quel que soit le mode de réalisation, l'écouvillon selon l'invention présente, sur une faible surface, une forte concentration de poils, bien supérieure à celle d'un écouvillon classique dans lequel les poils sont répartis radialement avec une faible densité, sur l'ensemble du pourtour.It should be noted that, whatever the embodiment, the swab according to the invention has, on a small surface, a high concentration of bristles, much greater than that of a conventional swab in which the bristles are distributed radially. with low density, all around.

Une forte concentration de poils permet à l'écouvillon selon l'invention d'exercer un meilleur effort mécanique et ainsi de décoller plus facilement les dépôts de lait ou de bouillie, particulièrement dans les zones difficiles à nettoyer.A high concentration of bristles allows the swab according to the invention to exert a better mechanical effort and thus easier to remove deposits of milk or slurry, particularly in areas difficult to clean.

Ainsi la tête 3 de nettoyage présente de part sa forte concentration des brins, plus de nervosité et permet également d'être utilisée, par exemple, pour le nettoyage du pas de vis de la cuve dans lequel des résidus de lait peuvent également s'être déposés.Thus, the cleaning head 3 has a high concentration of strands, more nervousness and can also be used, for example, for cleaning the screw of the tank in which milk residues may also be deposited.
