Definitions

  • the present invention relates to a jointing tape applicator between two plasterboards with automatic strip arrangement during filling, and a method of filling such an applicator.
  • a jointing tape applicator is intended for applying a strip of paper or similar material, in the form of a roll, between two adjacent plasterboards, during construction or renovation, using a pasty coating.
  • the plaster fills the space between the two plates and the strip holds everything together.
  • the tape is installed between two panels arranged on the same plane or at an angle. Once the plaster and the tape are in place, the user smooths the entire assembly using a flat or angled spatula for corners. The tape thus ensures a perfectly smooth joint between the panels.
  • a tubular coating conduit connected, in use, to a pump controlled by a trigger carried by the conduit.
  • the latter also comprises at its operational end a dispenser for a roll of jointing tape and a head for applying the tape.
  • the application head unrolls the tape against the plates and the user controls the pump so that it ejects coating under the tape.
  • This type of applicator is very bulky and tiring to handle, as a large part is cantilevered.
  • it is constantly connected to the pump throughout use, which makes it difficult to handle and requires carrying the weight of the hose.
  • it is expensive and complex, as it requires managing during the application of the strip, the supply of coating and the unwinding of the strip.
  • the systematic connection to the pump requires a waterproof connector, to avoid putting coating everywhere, which makes the design complex and fragile, and requires regular maintenance of the joints.
  • the second type of tape applicator commonly called a "banjo" and illustrated, for example, in the document US2328571 , includes a coating tank in which the strip is loaded with coating during application. It also includes a dispenser for a roll of jointing strip for carrying out numerous joints, particularly on large construction sites.
  • the tank has, with reference to the position of use, an inlet slot for the strip arranged between a free end of a rear wall of the tank and a first free end of a lower wall of the tank, and an outlet slot for the strip arranged between a free end of a front wall of the tank and a second free end of the lower wall of the tank.
  • the latter also includes two side walls, one of which constitutes a removable side cover for access to the interior of the tank.
  • the cover can be removable by removal or by pivoting.
  • This filling operation which is generally done manually with a plastering knife, is delicate because the plaster must be gently placed, without putting any outside the tank while keeping the strip in the filling position, that is to say against the front, rear and top walls. In practice, this operation is very messy and requires surprisingly a lot of know-how.
  • An objective of the present invention is therefore to provide a strip applicator which can be refilled quickly and easily, even by a novice user, which limits the risk of soiling during filling and which guarantees optimal and automatic positioning of the strip in the reservoir.
  • Another objective of the invention is to provide an applicator that is easy to handle when applying the strip, i.e. lightweight and without any connection pipe to a pump, in use.
  • Another objective is to offer an applicator with a simple and robust design, easy to maintain, and limiting the number and complexity of the parts that make it up.
  • Another objective of the invention is to provide an applicator ensuring a clean and traceless application, regardless of the position in which the user's hand grips it.
  • An objective of the present invention is to provide an application head allowing simple kinetics and handling of passage from the retracted position to the use position, without having to disassemble the entire head.
  • the applicator comprises a structure such that it must be filled upside down, i.e. with the bottom wall upwards.
  • an applicator is obtained whose filling is not only easy and not very messy, but also versatile, i.e. it can be carried out either manually by gravity or with a syringe, or with a pump intermittently connected to the applicator, and this without requiring a sealed connection with the pump by means of a sealed connector.
  • the upside-down filling allows the strip to be automatically placed perfectly in the filling position, i.e. against the front, rear and top walls, because it is driven by the weight of the coating which prevents twisting of the strip during filling.
  • the invention relates to an applicator for jointing tape between two plasterboards, as defined in claim 1.
  • the invention also relates to a method of filling an empty jointing tape applicator as defined in claim 10.
  • the invention also relates to a method of adding coating in a jointing tape applicator with a coating pump, as defined in claim 11.
  • FIG. 1 An applicator provided with an access port to the interior of the reservoir according to the invention is illustrated in Figure 1 .
  • the applicator 1 comprises a dispenser 2 for a roll of jointing tape 3 (illustrated in dotted lines) and a reservoir 4 of coating in which the tape is unrolled, in use.
  • the applicator also includes a gripping handle 5 for carrying or operational handling during application of the tape.
  • the applicator may include a gripping strap (S; see figure 8 ) allowing the applicator to be grasped from below.
  • the tank 4 has, with reference to the position of use, an entry slot 6 of the strip formed between a free end 7a of a rear wall 7 of the tank and a first free end 8a of a lower wall 8 of the tank.
  • the tank 4 also comprises an outlet slot 9 for the strip formed between a free end 10a of a front wall 10 of the tank and a second free end 8b of the lower wall 8 of the tank.
  • the tank further comprises two side walls 11 and 12, one of which constitutes a removable side cover 11 allowing access to the interior of the tank 4.
  • An application head 13 according to the invention is fixed to the front wall 10 of the reservoir 4.
  • the lower wall 8 comprises an orifice 14 provided with a removable plug 15 for access to the interior of the tank.
  • the orifice 13 is directed towards the upper wall 16 of the tank, that is to say it is directed upwards, by reference to the position of use illustrated in Figures 1 and 2 .
  • the orifice has an axis of symmetry XX perpendicular to the lower wall 8.
  • the orifice is opposite the strip when the latter is in the position of use and it extends into the tank between the inlet slot 6 and the outlet slot 9.
  • the coating enters perpendicular to the strip and pushes it by gravity towards the upper wall, as will be explained in relation to the figures 5 to 7 .
  • the filling of the reservoir is done “upside down”, that is to say that the applicator is turned over so that the lower wall 8 is at the top and the upper wall 16 is at the bottom.
  • the cap is removed to allow upside-down filling.
  • the plug can be made of elastomer and forcefully penetrate the orifice to ensure that it is closed.
  • the disadvantage is that the plug must not be too long so as not to protrude too far into the tank and risk tearing the strip when there is almost no more coating.
  • the orifice 14 is extended, towards the outside of the tank, by a peripheral crown 14a of determined height Hc. This crown allows the gripping of a plug which remains outside the tank.
  • the orifice 14 is circular and extended by a cylindrical crown 14a, which allows the use of a screw cap.
  • the screw cap used is a so-called “quarter turn” cap.
  • the cylindrical crown 14a comprises two fins 14b arranged centrifugally and diametrically opposite one another.
  • the cap comprises a crown of complementary shape, comprising two legs arranged centripetally and diametrically opposite one another, the legs being intended to be inserted by force between the fins and the lower wall when the cap is closed and to pass between the fins when the cap is pivoted a quarter turn to clear the orifice.
  • the lower wall 8 of the tank is advantageously concave, seen from the outside, relative to a base plane P passing through the first 8a and the second 8b free end of the lower wall.
  • These free ends 8a and 8b being straight line segments, the plane P is unique.
  • the lower wall 8 has a hollow of maximum height Hm, taken between the base plane P and a lowest point of the lower wall 8, greater than or equal to a height Ht of the orifice provided with the cap.
  • the height Ht represents the assembly of the orifice (including the crown where applicable) plus the cap, in the application position, that is to say when the cap is locked above the orifice.
  • the orifice is arranged in the hollow such that the plug does not protrude from the base plane P.
  • the plug when the plug is locked onto the orifice, the plug remains below the base plane or is flush with the base plane without exceeding it. Thanks to these characteristics of the hollow of the lower wall 8, it is ensured that the applicator can be placed stably on the free ends 8a and 8b, even with the orifice provided with the plug according to the invention. This also makes it possible to avoid any scraping of the plug against the plasterboard during application of the strip.
  • THE figures 5 to 7 illustrate the filling method according to the invention, enabled by the structure of the applicator and the arrangement of the orifice 14.
  • This filling is illustrated here with the feed pipe 21 of a coating pump 20 (illustrated in Figure 9 ).
  • a free end B1 of the strip B is first inserted into the reservoir through the inlet slot 6 and the free end B1 of the strip B is removed from the reservoir through the outlet slot 9. The strip then extends freely in the reservoir.
  • the side wall 11 forming the removable side cover is pivotally mounted by a hinge 11a on the upper wall 16, and comprises reversible fixing means 11b on the lower wall to allow reversible sealed closing of the cover.
  • the applicator is then turned over to put it in the upside-down position, so that the cap is in the upper position. It can then be opened and a supply pipe 21 of a pump 20 connected to a reservoir 30 of coating 31 can be inserted into the orifice 14.
  • the free end B1 of the strip B is held outside the tank and the pump is operated so that coating 31 enters the tank in the direction of arrow F1.
  • the coating 31 pushed by the pump tends to fall towards the bottom, that is to say towards the upper wall 16.
  • the coating 31 meets the strip and pushes it in the direction of the arrows F2 towards the upper wall 16, the rear wall 7 and the front wall 10 until the tank is filled ( Figure 7 ).

Description

La présente invention concerne un applicateur de bande de jointement entre deux plaques de plâtre à agencement automatique de bande pendant le remplissage, et un procédé de remplissage d'un tel applicateur.The present invention relates to a jointing tape applicator between two plasterboards with automatic strip arrangement during filling, and a method of filling such an applicator.

Un applicateur de bande de jointement est destiné à la pose d'une bande en papier ou matériau similaire, se présentant sous forme de rouleau, entre deux plaques de plâtre adjacentes, en construction ou en rénovation, et ceci par l'intermédiaire d'un enduit pâteux.A jointing tape applicator is intended for applying a strip of paper or similar material, in the form of a roll, between two adjacent plasterboards, during construction or renovation, using a pasty coating.

Ainsi, l'enduit comble l'espace entre les deux plaques et la bande maintient l'ensemble.Thus, the plaster fills the space between the two plates and the strip holds everything together.

La pose de bande se fait entre deux plaques disposées sur un même plan ou en angle. Une fois l'enduit et la bande positionnés, l'utilisateur lisse l'ensemble à l'aide d'une spatule plate ou coudée pour les angles. La bande assure ainsi d'obtenir un joint parfaitement lisse entre les plaques.The tape is installed between two panels arranged on the same plane or at an angle. Once the plaster and the tape are in place, the user smooths the entire assembly using a flat or angled spatula for corners. The tape thus ensures a perfectly smooth joint between the panels.

On connaît deux types d'applicateurs à bande.There are two known types of tape applicators.

Le premier, communément appelés « bazooka », est illustré, par exemple, dans le document US4105490 .The first, commonly called "bazooka", is illustrated, for example, in the document US4105490 .

Il comprend un conduit tubulaire d'enduit relié, en utilisation, à une pompe commandable par une gâchette portée par le conduit. Ce dernier comprend également à son extrémité opérationnelle un dévidoir d'une bande de jointement en rouleau et une tête d'application de la bande. En utilisation, la tête d'application déroule la bande contre les plaques et l'utilisateur commande la pompe pour qu'elle éjecte de l'enduit sous la bande.It comprises a tubular coating conduit connected, in use, to a pump controlled by a trigger carried by the conduit. The latter also comprises at its operational end a dispenser for a roll of jointing tape and a head for applying the tape. In use, the application head unrolls the tape against the plates and the user controls the pump so that it ejects coating under the tape.

Ce type d'applicateur est très encombrant et fatigant à manipuler, car une grande partie est en porte-à-faux. Par ailleurs, il est constamment relié à la pompe pendant toute l'utilisation, ce qui rend sa manipulation difficile et nécessite de porter le poids du tuyau. En outre, il est cher et complexe, car il faut gérer pendant la pose de la bande l'approvisionnement d'enduit et le déroulage de la bande. Dans ce type d'applicateur, il n'y a pas de réservoir dans lequel la bande se charge automatiquement en enduit. Enfin, la connexion systématique à la pompe exige un connecteur étanche, pour éviter de mettre de l'enduit partout, ce qui rend la conception complexe et fragile, et nécessite un entretien régulier des joints.This type of applicator is very bulky and tiring to handle, as a large part is cantilevered. In addition, it is constantly connected to the pump throughout use, which makes it difficult to handle and requires carrying the weight of the hose. In addition, it is expensive and complex, as it requires managing during the application of the strip, the supply of coating and the unwinding of the strip. In this type of applicator, there is no reservoir in which the strip is automatically loaded with coating. Finally, the systematic connection to the pump requires a waterproof connector, to avoid putting coating everywhere, which makes the design complex and fragile, and requires regular maintenance of the joints.

Le deuxième type d'applicateur de bande, communément appelé « banjo » et illustré, par exemple dans le document US2328571 , comprend un réservoir d'enduit dans lequel la bande se charge en enduit lors de l'application. Il comprend également un dévidoir d'une bande de jointement en rouleau pour effectuer de nombreux jointements, notamment sur les grands chantiers.The second type of tape applicator, commonly called a "banjo" and illustrated, for example, in the document US2328571 , includes a coating tank in which the strip is loaded with coating during application. It also includes a dispenser for a roll of jointing strip for carrying out numerous joints, particularly on large construction sites.

À cette fin, le réservoir présente, par référence à la position d'utilisation, une fente d'entrée de la bande ménagée entre une extrémité libre d'une paroi arrière du réservoir et une première extrémité libre d'une paroi inférieure du réservoir, et une fente de sortie de la bande ménagée entre une extrémité libre d'une paroi frontale du réservoir et une deuxième extrémité libre de la paroi inférieure du réservoir.For this purpose, the tank has, with reference to the position of use, an inlet slot for the strip arranged between a free end of a rear wall of the tank and a first free end of a lower wall of the tank, and an outlet slot for the strip arranged between a free end of a front wall of the tank and a second free end of the lower wall of the tank.

Pour remplir le réservoir, ce dernier comprend, en outre, deux parois latérales, dont l'une constitue un capot latéral amovible d'accès à l'intérieur du réservoir. Le capot peut être amovible par retrait ou par pivotement.To fill the tank, the latter also includes two side walls, one of which constitutes a removable side cover for access to the interior of the tank. The cover can be removable by removal or by pivoting.

Pour remplir les applicateurs de type banjo, on ouvre le capot, on place manuellement la bande contre les parois arrière, supérieure et frontale, puis on remplit l'espace ménagé entre la bande ainsi positionnée et la surface inférieure du réservoir avec de l'enduit.To fill the banjo-type applicators, open the hood, manually place the strip against the rear, top, and front walls, and then fill the space between the positioned strip and the lower surface of the tank with filler.

Cette opération de remplissage, qui se fait manuellement généralement avec un couteau à enduire, est délicate puisqu'il faut placer délicatement l'enduit, sans en mettre en dehors du réservoir tout en maintenant la bande en position de remplissage, c'est-à-dire contre les parois frontale, arrière et supérieure. En pratique, cette opération est très salissante et nécessite étonnamment beaucoup de savoir-faire.This filling operation, which is generally done manually with a plastering knife, is delicate because the plaster must be gently placed, without putting any outside the tank while keeping the strip in the filling position, that is to say against the front, rear and top walls. In practice, this operation is very messy and requires surprisingly a lot of know-how.

Le document US6367534 B1 décrit un banjo qui présente une valve antiretour sur sa face inférieure.The document US6367534 B1 describes a banjo that has a check valve on its underside.

Un objectif de la présente invention est donc de proposer un applicateur de bande qui peut être rechargé rapidement et facilement y compris par un utilisateur débutant, qui limite les risques de salissure lors du remplissage et qui garantit un positionnement optimal et automatique de la bande dans le réservoir.An objective of the present invention is therefore to provide a strip applicator which can be refilled quickly and easily, even by a novice user, which limits the risk of soiling during filling and which guarantees optimal and automatic positioning of the strip in the reservoir.

Un autre objectif de l'invention est de proposer un applicateur facilement manipulable lors de l'application de la bande, c'est-à-dire léger et dépourvu de tout tuyau de connexion à une pompe, en utilisation.Another objective of the invention is to provide an applicator that is easy to handle when applying the strip, i.e. lightweight and without any connection pipe to a pump, in use.

Un autre objectif est de proposer un applicateur de conception simple et robuste, facile d'entretien, et limitant le nombre et la complexité des pièces qui le constituent.Another objective is to offer an applicator with a simple and robust design, easy to maintain, and limiting the number and complexity of the parts that make it up.

Un autre objectif de l'invention est de proposer un applicateur assurant une application nette et sans trace, quelle que soit la position dans laquelle la main de l'utilisateur le saisit.Another objective of the invention is to provide an applicator ensuring a clean and traceless application, regardless of the position in which the user's hand grips it.

Un objectif de la présente invention est de proposer une tête d'application permettant une cinétique et une manipulation simples de passage de la position escamotée à la position d'utilisation, sans avoir à démonter l'ensemble de la tête.An objective of the present invention is to provide an application head allowing simple kinetics and handling of passage from the retracted position to the use position, without having to disassemble the entire head.

Selon l'invention, l'applicateur comprend une structure telle qu'il doit être rempli la tête en bas, c'est-à-dire la paroi inférieure vers le haut. Grâce à un tel remplissage, on obtient un applicateur dont le remplissage est non seulement facile et peu salissant, mais également polyvalent, c'est-à-dire pouvant être effectué soit manuellement par gravité soit avec une seringue, soit avec une pompe reliée de manière intermittente à l'applicateur, et ce sans nécessite une connexion étanche avec la pompe au moyen d'un raccord étanche. En outre, de manière inattendue, le remplissage tête en bas permet de placer automatiquement parfaitement la bande en position de remplissage, c'est-à-dire contre les parois frontale, arrière et supérieure, car elle est entraînée par le poids de l'enduit qui en évitant un vrillement de la bande lors du remplissage. Au contraire, si le remplissage s'effectuait tête en haut, c'est-à-dire la paroi inférieure vers le bas, il faudrait non seulement un raccord étanche avec la pompe, mais la bande risquerait de vriller dans le réservoir et de ne pas bien se positionner, car elle ne serait pas entraînée par le poids de l'enduit.According to the invention, the applicator comprises a structure such that it must be filled upside down, i.e. with the bottom wall upwards. By means of such filling, an applicator is obtained whose filling is not only easy and not very messy, but also versatile, i.e. it can be carried out either manually by gravity or with a syringe, or with a pump intermittently connected to the applicator, and this without requiring a sealed connection with the pump by means of a sealed connector. Furthermore, unexpectedly, the upside-down filling allows the strip to be automatically placed perfectly in the filling position, i.e. against the front, rear and top walls, because it is driven by the weight of the coating which prevents twisting of the strip during filling. On the contrary, if the filling were done head up, that is to say the lower wall downwards, not only would a watertight connection with the pump be required, but the strip would risk twisting in the tank and not being positioned correctly, because it would not be carried by the weight of the coating.

Ainsi, l'invention a pour objet un applicateur de bande de jointement entre deux plaques de plâtre, tel que défini dans la revendication 1.Thus, the invention relates to an applicator for jointing tape between two plasterboards, as defined in claim 1.

D'autres modes de réalisation particuliers sont définis dans les revendications 2 à 9.Other particular embodiments are defined in claims 2 to 9.

L'invention a également pour objet un procédé de remplissage d'un applicateur de bande de jointement vide tel que défini dans la revendication 10.The invention also relates to a method of filling an empty jointing tape applicator as defined in claim 10.

L'invention a également pour objet un procédé d'ajout d'enduit dans un applicateur de bande de jointement avec une pompe à enduit, tel que défini dans la revendication 11.The invention also relates to a method of adding coating in a jointing tape applicator with a coating pump, as defined in claim 11.

Un applicateur muni d'un orifice d'accès à l'intérieur du réservoir selon l'invention est illustré en figure 1.An applicator provided with an access port to the interior of the reservoir according to the invention is illustrated in Figure 1 .

L'applicateur 1 comprend un dévidoir 2 pour une bande de jointement en rouleau 3 (illustré en pointillé) et un réservoir 4 d'enduit dans lequel se déroule la bande, en utilisation.The applicator 1 comprises a dispenser 2 for a roll of jointing tape 3 (illustrated in dotted lines) and a reservoir 4 of coating in which the tape is unrolled, in use.

L'applicateur comprend également une poignée de préhension 5 servant à son transport ou sa manipulation opérationnelle lors de l'application de la bande.The applicator also includes a gripping handle 5 for carrying or operational handling during application of the tape.

Alternativement ou en combinaison, l'applicateur peut comprendre une sangle de préhension (S ; voir figure 8) permettant de saisir l'applicateur par le dessous.Alternatively or in combination, the applicator may include a gripping strap (S; see figure 8 ) allowing the applicator to be grasped from below.

Comme illustré en figure 2, le réservoir 4 présente, par référence à la position d'utilisation, une fente d'entrée 6 de la bande ménagée entre une extrémité libre 7a d'une paroi arrière 7 du réservoir et une première extrémité libre 8a d'une paroi inférieure 8 du réservoir.As illustrated in Figure 2 , the tank 4 has, with reference to the position of use, an entry slot 6 of the strip formed between a free end 7a of a rear wall 7 of the tank and a first free end 8a of a lower wall 8 of the tank.

Le réservoir 4 comprend également une fente de sortie 9 de la bande ménagée entre une extrémité libre 10a d'une paroi frontale 10 du réservoir et une deuxième extrémité libre 8b de la paroi inférieure 8 du réservoir.The tank 4 also comprises an outlet slot 9 for the strip formed between a free end 10a of a front wall 10 of the tank and a second free end 8b of the lower wall 8 of the tank.

Le réservoir comprenant, en outre, deux parois latérales 11 et 12, dont l'une constitue un capot latéral amovible 11 permettant l'accès à l'intérieur du réservoir 4.The tank further comprises two side walls 11 and 12, one of which constitutes a removable side cover 11 allowing access to the interior of the tank 4.

Une tête d'application 13 selon l'invention est fixée sur la paroi frontale 10 du réservoir 4.An application head 13 according to the invention is fixed to the front wall 10 of the reservoir 4.

Selon l'invention, la paroi inférieure 8 comprend un orifice 14 muni d'un bouchon amovible 15 d'accès à l'intérieur du réservoir. L'orifice 13 est dirigé vers de la paroi supérieure 16 du réservoir, c'est-à-dire qu'il est dirigé vers le haut, par référence à la position d'utilisation illustrée en figures 1 et 2. En d'autres termes, l'orifice présente un axe de symétrie X-X perpendiculaire à la paroi inférieure 8.According to the invention, the lower wall 8 comprises an orifice 14 provided with a removable plug 15 for access to the interior of the tank. The orifice 13 is directed towards the upper wall 16 of the tank, that is to say it is directed upwards, by reference to the position of use illustrated in Figures 1 and 2 . In other words, the orifice has an axis of symmetry XX perpendicular to the lower wall 8.

Ainsi, l'orifice est en regard de la bande lorsque cette dernière est en position d'utilisation et qu'elle s'étend dans le réservoir entre la fente d'entrée 6 et la fente de sortie 9.Thus, the orifice is opposite the strip when the latter is in the position of use and it extends into the tank between the inlet slot 6 and the outlet slot 9.

Ainsi, lors du procédé de remplissage selon l'invention, l'enduit entre perpendiculairement à la bande et la repousse par gravité vers la paroi supérieure, comme il sera expliqué en relation avec les figures 5 à 7.Thus, during the filling process according to the invention, the coating enters perpendicular to the strip and pushes it by gravity towards the upper wall, as will be explained in relation to the figures 5 to 7 .

Du fait de cet agencement, le remplissage du réservoir se fait « tête en bas », c'est-à-dire que l'on retourne l'applicateur de telle sorte que la paroi inférieure 8 se retrouve vers le haut et la paroi supérieure 16 se retrouve vers le bas.Due to this arrangement, the filling of the reservoir is done “upside down”, that is to say that the applicator is turned over so that the lower wall 8 is at the top and the upper wall 16 is at the bottom.

C'est dans cette position qu'est illustré l'applicateur 1 en figure 3, avant tout remplissage. Ainsi, l'orifice 14 est fermé de manière étanche par le bouchon 15.It is in this position that the applicator 1 is illustrated in Figure 3 , before any filling. Thus, the orifice 14 is sealed by the plug 15.

Comme illustré en figure 4, on retire le bouchon pour permettre le remplissage tête en bas.As illustrated in Figure 4 , the cap is removed to allow upside-down filling.

Dans un mode de réalisation très simple, le bouchon peut être en élastomère et pénétrer en force dans l'orifice pour assurer la fermeture de ce dernier. L'inconvénient est que le bouchon ne doit pas être trop long pour ne pas trop dépasser dans le réservoir et risquer de déchirer la bande lorsqu'il n'y a presque plus d'enduit.In a very simple embodiment, the plug can be made of elastomer and forcefully penetrate the orifice to ensure that it is closed. The disadvantage is that the plug must not be too long so as not to protrude too far into the tank and risk tearing the strip when there is almost no more coating.

De préférence, l'orifice 14 est prolongé, vers l'extérieur du réservoir, par une couronne périphérique 14a de hauteur déterminée Hc. Cette couronne permet la prise d'un bouchon qui reste à l'extérieur du réservoir.Preferably, the orifice 14 is extended, towards the outside of the tank, by a peripheral crown 14a of determined height Hc. This crown allows the gripping of a plug which remains outside the tank.

Avantageusement, l'orifice 14 est circulaire et prolongé par une couronne 14a cylindrique, ce qui permet d'utiliser un bouchon à vissage.Advantageously, the orifice 14 is circular and extended by a cylindrical crown 14a, which allows the use of a screw cap.

De préférence, le bouchon à vissage utilisé est un bouchon dit « quart de tour ».Preferably, the screw cap used is a so-called “quarter turn” cap.

Ainsi, la couronne cylindrique 14a comporte deux ailettes 14b agencées de manière centrifuge et diamétralement opposées l'une par rapport à l'autre.Thus, the cylindrical crown 14a comprises two fins 14b arranged centrifugally and diametrically opposite one another.

De manière complémentaire, le bouchon comporte une couronne ce forme complémentaire, comprenant deux pattes agencées de manière centripète et diamétralement opposée l'une par rapport à l'autre, les pattes étant destinées à s'insérer en force entre les ailettes et la paroi inférieure lorsque le bouchon est fermé et à passer entre les ailettes lorsque le bouchon est pivoté d'un quart de tour pour dégager l'orifice.In a complementary manner, the cap comprises a crown of complementary shape, comprising two legs arranged centripetally and diametrically opposite one another, the legs being intended to be inserted by force between the fins and the lower wall when the cap is closed and to pass between the fins when the cap is pivoted a quarter turn to clear the orifice.

Comme illustré en figure 5, la paroi inférieure 8 du réservoir est avantageusement concave, vue de l'extérieure, par rapport à un plan de base P passant par la première 8a et la deuxième 8b extrémité libre de la paroi inférieure. Ces extrémités libres 8a et 8b étant des segments de droite, le plan P est unique.As illustrated in Figure 5 , the lower wall 8 of the tank is advantageously concave, seen from the outside, relative to a base plane P passing through the first 8a and the second 8b free end of the lower wall. These free ends 8a and 8b being straight line segments, the plane P is unique.

La paroi inférieure 8 présente un creux de hauteur maximale Hm, prise entre le plan de base P et un point le plus bas de la paroi inférieure 8, supérieure ou égale à une hauteur Ht de l'orifice muni du bouchon. En d'autres termes, la hauteur Ht représente l'ensemble orifice (y compris la couronne le cas échéant) plus bouchon, en position d'application, c'est-à-dire quand le bouchon est verrouillé au-dessus de l'orifice.The lower wall 8 has a hollow of maximum height Hm, taken between the base plane P and a lowest point of the lower wall 8, greater than or equal to a height Ht of the orifice provided with the cap. In other words, the height Ht represents the assembly of the orifice (including the crown where applicable) plus the cap, in the application position, that is to say when the cap is locked above the orifice.

Selon l'invention, l'orifice est agencé dans le creux de telle sorte que le bouchon ne dépasse pas du plan de base P.According to the invention, the orifice is arranged in the hollow such that the plug does not protrude from the base plane P.

De cette manière, lorsque le bouchon est verrouillé sur l'orifice, le bouchon reste sous le plan de base ou affleure le plan de base sans le dépasser. Grâce à ces caractéristiques du creux de la paroi inférieure 8, on s'assure de pouvoir poser de manière stable l'applicateur sur les extrémités libres 8a et 8b, même avec l'orifice muni du bouchon selon l'invention. Cela permet également d'éviter tout raclage du bouchon contre les plaques de plâtre au cours de l'application de la bande.In this way, when the plug is locked onto the orifice, the plug remains below the base plane or is flush with the base plane without exceeding it. Thanks to these characteristics of the hollow of the lower wall 8, it is ensured that the applicator can be placed stably on the free ends 8a and 8b, even with the orifice provided with the plug according to the invention. This also makes it possible to avoid any scraping of the plug against the plasterboard during application of the strip.

Les figures 5 à 7 illustrent le procédé de remplissage selon l'invention, permis par la structure de l'applicateur et l'agencement de l'orifice 14.THE figures 5 to 7 illustrate the filling method according to the invention, enabled by the structure of the applicator and the arrangement of the orifice 14.

Ce remplissage est ici illustré avec le tuyau d'alimentation 21 d'une pompe à enduit 20 (illustrée en figure 9).This filling is illustrated here with the feed pipe 21 of a coating pump 20 (illustrated in Figure 9 ).

Pour remplir l'applicateur selon l'invention pour la première fois, on insère préalablement une extrémité libre B1 de la bande B dans le réservoir par la fente d'entrée 6 et on sort l'extrémité libre B1 de la bande B hors du réservoir par la fente de sortie 9. La bande s'étend alors librement dans le réservoir.To fill the applicator according to the invention for the first time, a free end B1 of the strip B is first inserted into the reservoir through the inlet slot 6 and the free end B1 of the strip B is removed from the reservoir through the outlet slot 9. The strip then extends freely in the reservoir.

Pour réaliser cette opération, il faut ouvrir le capot 11 afin d'accéder à l'intérieur du réservoir.To carry out this operation, you must open the cover 11 to access the inside of the tank.

Selon un mode de réalisation avantageux, la paroi latérale 11 formant le capot latéral amovible est montée de manière pivotante par une charnière 11a sur la paroi supérieure 16, et comprend des moyens de fixation réversible 11b sur la paroi inférieure pour permettre une fermeture réversible étanche du capot.According to an advantageous embodiment, the side wall 11 forming the removable side cover is pivotally mounted by a hinge 11a on the upper wall 16, and comprises reversible fixing means 11b on the lower wall to allow reversible sealed closing of the cover.

Cela permet un accès facilité à l'intérieur du réservoir, et évite de mettre de l'enduit dans la charnière en raclant son couteau à enduire contre la paroi inférieure si l'utilisateur décide de remplir le réservoir de manière traditionnelle.This allows easy access to the inside of the tank, and avoids getting filler in the hinge by scraping the filler knife against the bottom wall if the user decides to fill the tank the traditional way.

On retourne ensuite l'applicateur pour le mettre en position tête en bas, de sorte que le bouchon se retrouve en position supérieure. On peut alors l'ouvrir et insérer dans l'orifice 14 un tuyau d'alimentation 21 d'une pompe 20 reliée à un réservoir 30 d'enduit 31.The applicator is then turned over to put it in the upside-down position, so that the cap is in the upper position. It can then be opened and a supply pipe 21 of a pump 20 connected to a reservoir 30 of coating 31 can be inserted into the orifice 14.

On maintenir l'extrémité libre B1 de la bande B hors du réservoir et on actionne la pompe pour que de l'enduit 31 entre dans le réservoir dans le sens de la flèche F1. Dans le réservoir, l'enduit 31 poussé par la pompe tend à tomber vers le fond, c'est-à-dire vers la paroi supérieure 16. Sur son chemin, comme illustré en figure 6, l'enduit 31 rencontre la bande et la repousse dans le sens des flèches F2 vers la paroi supérieure 16, la paroi arrière 7 et la paroi frontale 10 jusqu'à ce que le réservoir soit rempli (figure 7).The free end B1 of the strip B is held outside the tank and the pump is operated so that coating 31 enters the tank in the direction of arrow F1. In the tank, the coating 31 pushed by the pump tends to fall towards the bottom, that is to say towards the upper wall 16. On its way, as illustrated in Figure 6 , the coating 31 meets the strip and pushes it in the direction of the arrows F2 towards the upper wall 16, the rear wall 7 and the front wall 10 until the tank is filled ( Figure 7 ).

Le rouleau de bande étant libre de tourner, la bande s'étend automatiquement dans le réservoir, sans que l'utilisateur n'ait à la positionner.Since the tape roll is free to rotate, the tape automatically extends into the reservoir, without the user having to position it.

En outre, de manière inattendue, cette position d'applicateur tête en bas et ce mode de remplissage évite tout phénomène de vrillement de la bande qui s'applique parfaitement contre les parois du réservoir.Furthermore, unexpectedly, this upside-down applicator position and this filling method avoids any twisting of the strip, which is perfectly applied against the walls of the tank.

Une fois ce dernier rempli, on sort le tuyau d'alimentation 21 de la pompe hors de l'orifice 14 et on ferme le bouchon pour obtenir un applicateur de bande de jointement plein prêt à l'emploi.Once the latter is filled, the feed pipe 21 of the pump is removed from the orifice 14 and the cap is closed to obtain a full jointing tape applicator ready for use.

Ce mode de remplissage est particulièrement intéressant en cours d'opération d'application de bande, lorsqu'il faut recharger le réservoir en enduit le réservoir étant presque vide, mais aillant déjà servi.This filling method is particularly useful during a tape application operation, when the tank needs to be refilled with coating, the tank being almost empty, but having already been used.

Dans ce cas, la bande s'étend déjà librement dans le réservoir, une extrémité libre de la bande sortant hors du réservoir par la fente de sortie.In this case, the strip already extends freely in the tank, with one free end of the strip exiting the tank through the exit slot.

On retourne alors l'applicateur pour le mettre en position tête en bas, et on ouvre le bouchon 15 de l'orifice 14 porté par la paroi inférieure 8 du réservoir 4.The applicator is then turned over to put it in the upside-down position, and the cap 15 of the orifice 14 carried by the lower wall 8 of the reservoir 4 is opened.

On insère alors dans l'orifice 14 un tuyau d'alimentation 21 d'une pompe reliée à un réservoir d'enduit, puis on maintient l'extrémité libre B1 de la bande hors du réservoir et on actionne la pompe pour que de l'enduit entre dans le réservoir.A feed pipe 21 of a pump connected to a coating reservoir is then inserted into the orifice 14, then the free end B1 of the strip is held outside the reservoir and the pump is operated so that coating enters the reservoir.

Dans un mode de réalisation non illustré, la deuxième extrémité libre 8b de la paroi inférieure ou la tête d'application ou la paroi frontale comprend un moyen de maintien temporaire de la bande, pour empêcher le recul de la bande lors du remplissage. Par exemple, des moyens de réglage en hauteur de la bande peuvent être utilisés pour bloquer la bande temporairement.In a non-illustrated embodiment, the second free end 8b of the lower wall or the application head or the front wall comprises a means for temporarily holding the strip, to prevent the strip from moving back during filling. For example, means for adjusting the height of the strip may be used to temporarily block the strip.

Comme précédemment décrit, l'enduit entre dans le réservoir perpendiculairement à la bande et la repousse par gravité vers la paroi supérieure, la paroi arrière et la paroi frontale jusqu'à ce que le réservoir soit rempli.As previously described, the coating enters the tank perpendicular to the belt and pushes it by gravity towards the top wall, the back wall and the front wall until the tank is filled.

On sort alors le tuyau d'alimentation 21 de la pompe hors de l'orifice 14 et on ferme le bouchon 15 pour obtenir un applicateur de bande de jointement plein, à nouveau prêt à l'emploi.The feed pipe 21 of the pump is then removed from the orifice 14 and the cap 15 is closed to obtain a full jointing tape applicator, ready for use again.

Avantageusement, un lien de liaison souple 15a est fixé entre le bouchon 15 et la paroi inférieure 8 du réservoir 4, ce qui évite de perdre le bouchon.Advantageously, a flexible connecting link 15a is fixed between the cap 15 and the lower wall 8 of the tank 4, which prevents the cap from being lost.

Ce faisant, il n'est pas nécessaire d'ouvrir le capot et de replacer manuellement la bande dans un réservoir recouvert d'enduit. L'opération de recharge est donc très propre et rapide. On peut utiliser une pompe, une seringue ou un entonnoir pour déposer l'enduit manuellement.In doing so, it is not necessary to open the hood and manually replace the strip into a coated tank. The operation of Refilling is therefore very clean and quick. You can use a pump, a syringe or a funnel to apply the coating manually.

Afin de permettre le remplissage tête en bas, l'applicateur selon l'invention comprend deux crochets de fixation 17 destinés à permettre, lors d'un remplissage du réservoir avec de l'enduit, la fixation de l'applicateur contre le bord d'un seau d'enduit (voir figure 9), de telle sorte que le bouchon et la paroi inférieure du réservoir soient dirigés vers le haut.In order to allow upside-down filling, the applicator according to the invention comprises two fixing hooks 17 intended to allow, when filling the reservoir with coating, the fixing of the applicator against the edge of a bucket of coating (see Figure 9 ), so that the cap and the bottom wall of the tank are facing upwards.

Les crochets 17 sont portés par l'une au moins des parois latérales 11 ou 12, ou par une plaque surnuméraire fixée à l'une ou l'autre des parois latérales 11 ou 12.The hooks 17 are carried by at least one of the side walls 11 or 12, or by an additional plate fixed to one or other of the side walls 11 or 12.

Sur la figure 8, l'applicateur 1 comprend une telle plaque surnuméraire 40 fixée à la paroi 12, cette plaque 40 portant le dévidoir 2 de la bande en rouleau.On the figure 8 , the applicator 1 comprises such an additional plate 40 fixed to the wall 12, this plate 40 carrying the dispenser 2 of the roll of tape.

La plaque surnuméraire permet de proposer un applicateur pour droitier ou pour gaucher, selon la paroi latérale 11 ou 12 sur laquelle elle est fixée. En la fixant à la paroi 11, on inverse simplement la place du dévidoir 2, et on obtient un applicateur pour gaucher, comme expliqué ci-après.The additional plate makes it possible to provide a right-handed or left-handed applicator, depending on the side wall 11 or 12 on which it is fixed. By fixing it to the wall 11, the position of the dispenser 2 is simply reversed, and a left-handed applicator is obtained, as explained below.

Selon l'invention, les crochets 17 comprennent une aile de fixation 17a à la paroi latérale du réservoir (ou à la plaque surnuméraire 40).According to the invention, the hooks 17 comprise a wing 17a for fixing to the side wall of the tank (or to the additional plate 40).

L'aile de fixation 17a est prolongée angulairement par une aile d'appui 17b contre un bord 32 de seau (voir figure 9), lors d'un remplissage du réservoir avec de l'enduit.The fixing wing 17a is angularly extended by a support wing 17b against an edge 32 of the bucket (see Figure 9 ), when filling the tank with filler.

Selon l'invention, l'aile d'appui 17b est prolongée angulairement par une aile de blocage 17c destinée à bloquer l'applicateur contre la paroi du seau lors d'un remplissage du réservoir avec de l'enduit, et à empêcher le basculement de l'applicateur pendant le remplissage et une fois rempli.According to the invention, the support wing 17b is angularly extended by a blocking wing 17c intended to block the applicator against the wall of the bucket when filling the reservoir with coating, and to prevent the applicator from tipping over during filling and once filled.

L'aile de fixation 17a de chaque crochet 17 comporte avantageusement une rainure 17d pour le passage d'une sangle de préhension S de l'applicateur, cette sangle étant destinée à recevoir la main de l'utilisateur, dans une position telle que les doigts de l'utilisateur sont au contact de la paroi inférieure 8 lors de l'application de la bande.The fixing wing 17a of each hook 17 advantageously comprises a groove 17d for the passage of a gripping strap S of the applicator, this strap being intended to receive the user's hand, in a position such that the user's fingers are in contact with the lower wall 8 during application of the strip.

De cette manière, lorsque les crochets sont fixés sur une plaque surnuméraire 40, elle-même fixée à l'une ou l'autre des parois latérales 11-12, il est possible d'inverser la position de la plaque surnuméraire et de la fixer sur l'autre paroi latérale. On inverse alors la fixation du dévidoir 2 et des crochets 17, de sorte que l'utilisateur peut utiliser son autre main pour mettre en œuvre l'applicateur selon l'invention.In this way, when the hooks are fixed on a supernumerary plate 40, itself fixed to one or other of the side walls 11-12, it is possible to reverse the position of the supernumerary plate and fix it on the other side wall. The fixing of the reel 2 and the hooks 17 is then reversed, so that the user can use his other hand to implement the applicator according to the invention.
