Description

APPAREIL DISTRIBUTEUR DE MATERIAUX PREDECOUPES ENROULES EN BOBINE OU PLIES EN « Z »  DISTRIBUTOR APPARATUS FOR PRE-COATED ROLL-IN OR Z-FOLDED MATERIALS
L'invention se rattache au secteur technique des appareils de matériaux prédécoupés enroulés en bobine ou pliés en « Z », en particulier pour des matériaux d'essuyage de type essuie-mains, papier toilette, essuie- tout, en papier, ouate de cellulose, en matériau non tissé. Pour la bonne compréhension de l'invention, il y a lieu de rappeler préalablement les différentes recherches et développement effectuées par les Demandeur qui ont contribué à la recherche d'une solution nouvelle de la distribution de matériaux prédécoupés. Le Demandeur a développé un appareil distributeur de matériaux d'essuyage prédécoupés, objet du brevet français 2 931 350. Cet appareil est du type comprenant un carter formant réceptacle avec une plaque de fond, une paroi horizontale inférieure et des parois latérales avec un couvercle articulé sur un axe. Cet appareil comprend en outre un volet articulé par rapport aux parois du carter dans la partie inférieure de ce dernier, selon l'enseignement de ce brevet. Ce volet est fixé par clipsage par rapport aux dites parois pour lui permettre d'être positionné dans un plan vertical. Dans sa partie supérieure, le volet présente une forme avantageusement curviligne, et dans sa partie inférieure, une découpe centrale sensiblement en demi- cercle pour permettre la sortie du matériau d'essuyage prédécoupé. Le couvercle présente également sur sa face inférieure une découpe centrale similaire à la découpe précitée. Ces dites découpes centrales sur le volet et le couvercle ont pour fonction unique et exclusivement de permettre la sortie de la bande de matériau lors de sa préhension et tirage par l'utilisateur. Le matériau d'essuyage (M) dans cette mise en œuvre est établi sous forme d'une bande enroulée en bobine en étant prédécoupée, ou il peut se présenter en position pré-pliée en Z. The invention relates to the technical sector of the apparatus of pre-cut materials wound in coil or folded in "Z", in particular for wiping materials such as hand towels, toilet paper, paper towels, paper, cellulose wadding , of nonwoven material. For the good understanding of the invention, it is necessary to recall beforehand the different research and development carried out by the Applicants who contributed to the search for a new solution of the distribution of precut materials. The Applicant has developed a dispensing apparatus for pre-cut wiping materials, object of the French patent 2 931 350. This device is of the type comprising a housing forming a receptacle with a bottom plate, a lower horizontal wall and side walls with a hinged lid on an axis. This apparatus further comprises a hinged flap relative to the housing walls in the lower part of the latter, according to the teaching of this patent. This shutter is fixed by clipping relative to said walls to allow it to be positioned in a vertical plane. In its upper part, the flap has an advantageously curvilinear shape, and in its lower part, a central cut substantially in a semicircle to allow the output of the pre-cut wiping material. The cover also has on its underside a central cutout similar to the aforementioned cut. These so-called central cuts on the shutter and the cover have the sole and exclusive function of allowing the exit of the strip of material during its gripping and pulling by the user. The wiping material (M) in this embodiment is established in the form of a coil-wound strip being pre-cut, or it may be in a pre-bent Z-position.
Selon le brevet français précité, la partie basse de l'appareil à l'endroit de sortie du matériau présente des butées opposées de part et d'autre de la bande de matériau en assurant la séparation d'un format de bande par rapport à la ligne de prédécoupe en regard de la bande. L'effort de traction va assurer en fin de passage de la bande entre la paroi avant du volet et la face en regard du couvercle la séparation d'un format de bande par rapport au reste de la bobine ou de la pile de matériau plié en Z grâce aux dites butées. Selon ce brevet, il a été précisé que les dites butées sont réglables en position de part et d'autre de l'ouverture de sortie de la bande de matériau, et ce, par des moyens de coulissement appropriés. According to the abovementioned French patent, the lower part of the apparatus at the exit point of the material has opposite stops on either side of the strip of material, ensuring the separation of a strip format with respect to the pre-cut line next to the band. The tensile force will ensure at the end of the passage of the strip between the front wall of the flap and the face facing the cover the separation of a strip format relative to the remainder of the coil or the stack of folded material. Z thanks to said stops. According to this patent, it has been specified that said stops are adjustable in position on either side of the outlet opening of the material strip, and this by appropriate sliding means.
Le Demandeur a constaté que lors de la sortie de la bande de matériau se produisait un effet de froissement de la bande de matériau dû à l'effet de rétrécissement de la bande de matériau lors de son passage entre les butées. Sur le principe, cela est nullement gênant, car la plupart des utilisateurs n'attachent pas d'importance à la présentation de la bande de matériau découpé de par l'usage qui en est fait ensuite avec forcément un pliage lors de la fonction essuie-main, essuie-tout, Pour répondre néanmoins à cette problématique, le Demandeur a conçu un nouvel appareil objet du brevet F 2 960 760. Succinctement, l'appareil comprend un carter avec un couvercle articulé et agencé sur un axe, et un volet articulé sur les parois latérales du carter. La bande de matériau à l'état prédécoupé ou pré -plié en Z est susceptible de contourner la partie supérieure de forme curviligne disposée en extrémité haute du volet. La bande de matériau (M) passe ainsi devant le volet et contre la face intérieure du couvercle. Dans sa partie basse, le couvercle présente une découpe centrale et le volet une découpe centrale pour le passage et l'évacuation de la bande de matériau. Le volet et le couvercle présentent des couples de formes complémentaires curvilignes en forme d'arc-en-ciel susceptibles de s 'emboîter partiellement lors du passage de la bande de matériau et plus spécifiquement les parties sont les nervures et les rainures. Dans le cadre de ce brevet F 2 960 760 et pour réduire au maximum tout effet de froissement du matériau lors de son passage entre les formes d'emboîtement complémentaires, il est prévu que la bande de matériau soit déroulée complètement entre le volet et la paroi intérieure du couvercle, sans déformation latérale, et en débordant de part et d'autre, des formes complémentaires mâles-femelles établies selon les couples rainures-nervures formées sur le volet et le couvercle, et ce, en l'absence de toutes butées. Ces formes complémentaires constitutives de rainures et de nervures sont nombreuses et donnent une configuration en arc-en-ciel, selon une amplitude sensiblement plus importante que 180°. Ces formes sont agencées directement ou avec un moyen complémentaire réducteur d'espace entre certaines parties de nervures et de rainures pour permettre et faciliter la séparation d'un format de bande de matériau, lors de la traction par l'utilisateur. Ces formes ont une section en hauteur toujours constante sur tout leur développement de configuration curviligne et la hauteur est strictement la même pour chaque couple de rainures ou de nervures. Il est possible que les ensembles de rainures-nervures formés sur le carter ne soient pas concentriques avec les ensembles de nervures-rainures formés sur le couvercle. Cependant, les hauteurs restent strictement les mêmes. Ce moyen complémentaire constitué par des formes en saillies formant dents a pour but de rétrécir l'espace entre les rainures et les nervures lors de leur emboîtement. Cette réduction d'espace entraine la formation de zones de retenue de la bande de matériau favorisant l'amorce de son déchirement. Ces empreintes ou dents sont disposées en extrémité basse de la forme en arc-en-ciel obtenue par la concentricité, et favorisent la séparabilité du matériau en cas de traction. The Applicant has found that during the exit of the strip of material occurs a creasing effect of the material strip due to the narrowing effect of the material strip during its passage between the stops. In principle, this is not a problem, because most users do not attach importance to the presentation of the strip of material cut by the use that is made of it with inevitably folding during wiper function. However, to meet this problem, the Applicant has designed a new apparatus subject to the patent F 2 960 760. Briefly, the apparatus comprises a housing with an articulated lid and arranged on an axis, and an articulated flap on the side walls of the housing. The strip of pre-cut or pre-folded Z-shaped material is likely to bypass the upper portion of curvilinear shape disposed at the upper end of the flap. The strip of material (M) thus passes in front of the shutter and against the inner face of the cover. In its lower part, the cover has a central cutout and the shutter a central cutout for the passage and evacuation of the material strip. The flap and the cover have pairs of curvilinear complementary shapes in the form of a rainbow that can partially fit during the passage of the strip of material and more specifically the parts are the ribs and grooves. In the context of this patent F 2 960 760 and to minimize any wrinkling effect of the material during its passage between complementary forms of interlocking, it is expected that the strip of material is unrolled completely between the shutter and the wall internal cover without lateral deformation, and overflowing on either side, male-female complementary shapes established according to the groove-rib couples formed on the flap and the cover, and this, in the absence of any stops. These complementary forms constituting grooves and ribs are numerous and give a rainbow configuration, with an amplitude substantially greater than 180 °. These shapes are arranged directly or with a complementary space-reducing means between certain portions of ribs and grooves to allow and facilitate the separation of a material strip format during traction by the user. These shapes have an always constant height section throughout their development of curvilinear configuration and the height is strictly the same for each pair of grooves or ribs. It is possible that the groove-rib assemblies formed on the housing are not concentric with the rib-groove assemblies formed on the cover. However, the heights remain strictly the same. This complementary means consisting of protruding shapes forming teeth is intended to narrow the space between the grooves and the ribs during their nesting. This reduction of space causes the formation of retention zones of the strip of material favoring the initiation of its tearing. These fingerprints or teeth are arranged at the lower end of the rainbow shape obtained by the concentricity, and promote the separability of the material in case of traction.
Ce matériau se trouve en quelque sorte passant entre les formes rainures-nervures complémentaires. L'objectif visé à l'origine de cette invention d'éviter un froissement de la bande de matériau n'est pas totalement atteint pour des problèmes d'épaisseur de matériaux que l'on trouve sur les marchés et proposés par de nombreux fabricants. Par ailleurs et comme dans le brevet français F 2 931 350, les découpes centrales formées sur le volet et le couvercle ont pour fonction unique et exclusive de permettre la sortie de la bande de matériau lors de sa préhension et tirage par l'utilisateur. This material is in some way passing between complementary groove-rib shapes. The original purpose of this invention to prevent wrinkling of the web of material is not fully achieved for material thickness problems found on the markets and proposed by many manufacturers. Furthermore and as in French Patent F 2 931 350, the central cutouts formed on the shutter and the cover have the sole and exclusive function of allowing the exit of the strip of material during its gripping and pulling by the user.
Le Demandeur a aussi développé dans la demande de brevet français 1058449 un appareil distributeur de matériaux d'essuyage comprenant un carter de fixation recevant un couvercle articulé pour sa fermeture en relevage, le carter recevant un module fixé de manière démontable. Ce module est lui-même agencé avec un volet disposé en regard de la face interne du couvercle, la bande de matériau passant entre le volet et la paroi interne du couvercle. Les découpes centrales formées sur le couvercle et le volet ont toujours les mêmes fonctions qu'indiquer précédemment. Le Demandeur a aussi développé un perfectionnement pour le passage de la bande de matériau entre le volet et la paroi intérieure du couvercle, solution décrite et illustrée dans le brevet français FR 1 161439. Le carter forme un réceptacle de matériau d'essuyage prédécoupé en bobine ou à l'état pré -plié. Le couvercle est articulé par rapport au carter. Le volet est monté entre les flasques latéraux du carter. Dans le plan supérieur au dit volet est disposée une barre de renvoi qui est montée libre en rotation entre les flasques du dit carter pour permettre le renvoi de la bande de matériau tirée entre le volet et la face interne du couvercle. La face intérieure du couvercle et la face apparente en regard du volet sont agencées avec des couples de rainures et de nervures. La solution apportée, selon ce brevet français FR 1 161439, vise à former et à disposer entre le couple de nervures- rainures de plus petit diamètre et intérieur et l'ouverture formée sur le volet et le couvercle pour le passage du matériau une zone d'appui ayant la forme d'un croissant. The Applicant has also developed in the French patent application 1058449 a wipe material dispensing apparatus comprising a fixing housing receiving a hinged lid for closing in lifting, the housing receiving a removably fixed module. This module is itself arranged with a flap disposed opposite the inner face of the cover, the strip of material passing between the flap and the inner wall of the cover. The central cuts formed on the lid and the shutter always have the same functions as indicated above. The Applicant has also developed an improvement for the passage of the web of material between the flap and the inner wall of the cover, a solution described and illustrated in French patent FR 1 161439. The housing forms a wiper material receptacle precut coil or in the pre-folded state. The lid is hinged relative to the housing. The flap is mounted between the side flanges of the housing. In the plane above said flap is disposed a return bar which is mounted free to rotate between the flanges of said housing to allow the return of the strip of material drawn between the flap and the inner face of the lid. The inner face of the cover and the apparent face facing the flap are arranged with pairs of grooves and ribs. The solution provided, according to this French patent FR 1 161439, aims at forming and arranging between the pair of grooves-grooves of smaller diameter and inside and the opening formed on the shutter and the cover for the passage of the material a zone d support in the shape of a crescent.
Selon ce brevet, les parties d'extrémités inférieures des couples rainures-nervures sont agencées avec des formes en saillies et en creux formées transversalement respectivement sur les nervures du volet et du couvercle puis dans les rainures du volet et du couvercle. De manière spécifique, le volet et le couvercle sont agencés en partie d'extrémité des couples de nervures et de rainures avec une patte transversale méplate de petite épaisseur autorisant le positionnement et la fixation sur la patte de réception d'une bande souple en un matériau différent et déformable. Les bandes présentent une configuration complémentaire aux nervures et aux rainures pour assurer une continuité avec ces dernières. La hauteur des nervures est toujours constante. Les découpes centrales formées sur le couvercle et le volet ont toujours les mêmes fonctions que précédemment. Dans une autre réalisation décrite dans le brevet français FR 1 161439, dans sa configuration, le volet et le couvercle présentent en regard une pluralité de couples de formes complémentaires disposées en arc-en-ciel susceptibles de s 'emboîter les unes dans les autres après fermeture du couvercle, ces dites formes complémentaires étant des formes ondulées présentant, en alternance, des formes successives bombées et creuses en évitant ainsi toute aspérité ou zone tranchante par une ou des arête(s) vive(s). De plus, en combinaison, l'une des formes ondulées, soit sur le volet, soit sur la partie intérieure du couvercle, présente transversalement près de son extrémité une cavité creuse ayant un profil curviligne ou en demi-cercle. Par ailleurs, en combinaison, ladite cavité est bordurée par une forme d'extrémité ondulée ayant la même courbure que les ondulations formées soit sur le volet, soit la partie intérieure du couvercle. Ladite forme d'extrémité ondulée adjacente à la cavité creuse profilée constitue par sa face interne une zone de butée de la bande de matériau tirée. Toutes lesdites formes ondulées ont une forme régulière. Par ailleurs, les découpes centrales formées sur le couvercle et le volet ont toujours les mêmes fonctions que précédemment. En pratique, toutes les solutions précédemment explicitées duAccording to this patent, the lower end portions of the groove-rib couples are arranged with protruding and recessed shapes formed transversely respectively on the ribs of the shutter and the cover and then in the grooves of the shutter and the cover. Specifically, the flap and the cover are arranged at the end of the pairs of ribs and grooves with a thin flat transverse tab allowing the positioning and fixing on the receiving tab of a flexible strip of a material different and deformable. The strips have a configuration complementary to the ribs and grooves to ensure continuity with the latter. The height of the ribs is always constant. The central cutouts formed on the cover and the shutter always have the same functions as before. In another embodiment described in French Patent FR 1 161439, in its configuration, the flap and the cover have opposite a plurality of pairs of complementary shapes arranged in rainbow that may fit into each other after closure of the lid, said complementary shapes being corrugated shapes having, alternately, successive convex and hollow shapes thus avoiding any roughness or cutting area by one or more sharp edge (s). In addition, in combination, one of the corrugated shapes, either on the flap or on the inner part of the cover, has transversely near its end a hollow cavity having a curvilinear profile or in a semicircle. Furthermore, in combination, said cavity is bordered by a corrugated end shape having the same curvature as the corrugations formed either on the flap or the inner part of the lid. Said corrugated end shape adjacent to the profiled hollow cavity constitutes, by its internal face, an abutment zone of the drawn material strip. All said wavy shapes have a regular shape. Furthermore, the central cutouts formed on the cover and the shutter always have the same functions as before. In practice, all previously explained solutions of the
Demandeur témoignent de recherches continues pour toujours améliorer les conditions de fonctionnement de ces appareils distributeurs de bandes de matériaux prédécoupés avec une problématique liée aux variations très substantielles dans la qualité desdits matériaux, dans leurs épaisseurs, grammages, ouates, matériaux non tissés, cités à titre d'exemples non limitatifs. La multiplicité des différents dépôts de brevets par le Demandeur qui a pourtant plus de 40 ans d'expérience sur ce type d'appareils (premier dépôt en 1968) témoigne de la difficulté à résoudre tous les problèmes. C'est donc dans cette recherche constante d'amélioration que le Demandeur a conçu un appareil de distribution de matériaux prédécoupés totalement différent de l'art antérieur précité en vue de la distribution de la bande de matériau tirée par l'utilisateur, et ce, quelle que soit la nature du matériau distribué, papier, ouate de cellulose, matériau non tissé, y compris les bandes de matériaux très peu épaisses et fragiles. Cette conception nouvelle même de l'appareil distributeur lui permet d'avoir une configuration compacte, simplifiée à l'extrême, économique, avec une présentation parfaite de la bande de matériau en sortie dudit appareil et aussi du format du matériau se présentant pour être prélevé. Applicant testify to continuous research to always improve the operating conditions of these dispensers strips of precut material with a problem related to very substantial variations in the quality of said materials, in their thicknesses, grammages, wadding, nonwoven materials, cited as non-limiting examples. The multiplicity of different patent filings by the Claimant who has more than 40 years of experience on this type of device (first filing in 1968) shows the difficulty in solving all the problems. It is therefore in this constant search for improvement that the Applicant has devised a pre-cut material dispensing apparatus totally different from the aforementioned prior art for the purpose of dispensing the web of material drawn by the user, and this whatever the nature of the material dispensed, paper, cellulose wadding, nonwoven material, including strips of very thin and fragile materials. This new design even of the dispenser device allows it to have a compact configuration, simplified to the extreme, economic, with a perfect presentation of the strip of material output of said apparatus and also the format of the material to be taken .
Selon une première caractéristique, l'appareil distributeur de matériaux prédécoupés enroulés en bobine ou pliés en « Z » comprend un carter formant réceptacle avec une plaque de fond, une paroi horizontale inférieure, des parois verticales avec un couvercle articulé à la base du carter et étant relevé par le haut pour sa fermeture, l'appareil comprenant un volet fixé par rapport aux parois latérales du carter en étant positionné verticalement, ledit volet présentant dans sa partie supérieure une configuration curviligne pour le passage et le guidage de la bande de matériau prédécoupé, ladite bande de matériau passant entre ledit volet et ledit couvercle, ledit volet et ledit couvercle présentant chacun une découpe centrale identique pour permettre la sortie de la bande de matériau prédécoupé et sa préhension, ledit appareil distributeur étant remarquable en ce que le volet présente autour de la bordure périphérique de ladite découpe, une forme ayant une configuration curviligne sur tout le pourtour de la bordure périphérique de ladite découpe centrale formée sur le volet en étant dans un plan perpendiculaire au plan du volet, et en ce que ladite forme a une hauteur différenciée progressive de sa partie centrale correspondant à la partie haute de la découpe centrale jusqu'à ses extrémités en formant rampe, lesdites extrémités de la dite forme assurant une fonction de pénétration dans la bande de matériau dans la ligne de prédécoupe de ce dernier pour assurer ensuite le déchirement transversal complet et la séparation d'un format de matériau. According to a first feature, the distributor apparatus for pre-cut materials wound in a coil or folded in "Z" comprises a housing forming a receptacle with a bottom plate, a lower horizontal wall, vertical walls with a hinged cover at the base of the casing and being raised from above for its closure, the apparatus comprising a flap fixed relative to the side walls of the casing being positioned vertically, said flap having in its upper part a curvilinear configuration for the passage and guiding of the strip of pre-cut material said strip of material passing between said flap and said cover, said flap and said cover each having an identical central cut-out to allow the exit of the pre-cut material strip and its gripping, said dispensing apparatus being remarkable in that the shutter has around of the peripheral edge of said cut, an ay shape a curvilinear configuration around the periphery of the peripheral edge of said central cutout formed on the shutter being in a plane perpendicular to the plane of the flap, and in that said shape has a progressive differentiated height of its central part corresponding to the part high of the central cutout to its ends forming a ramp, said ends of said shape providing a function of penetration into the web of material in the precut line of the latter to then ensure complete transverse tearing and separation of a material format.
Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description. These and other characteristics will be apparent from the rest of the description.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustré aux figures des dessins. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.
L'appareil distributeur de matériaux prédécoupés enroulés en bobine ou pliés en « Z » est référencé dans son ensemble par (A). The dispensing apparatus for pre-cut materials wound in a reel or folded in "Z" is referenced as a whole by (A).
Les matériaux prédécoupés sont par exemple des matériaux d'essuyage, en papier, en ouate de cellulose. Ils peuvent être des matériaux non tissés.  The pre-cut materials are for example wiping materials, paper, cellulose wadding. They can be non-woven materials.
L'appareil comprend un carter (1) formant réceptacle avec une plaque de fond (la), une paroi horizontale inférieure (lb), des parois latérales (le) avec un couvercle (2) articulé par rapport au carter par un assemblage ergot ou axe (2a) avec trou de réception, et ce, de manière bien connue. La bande de matériau est référencée par (B). Le couvercle est relevé par le haut pour sa fermeture. Il comprend, en outre, un volet (3) articulé par rapport aux deux parois latérales du carter en étant fixé de manière démontable par clipsage à l'aide d'axes ou d'ergots de positionnement dans des ouvertures réceptrices formées sur les parois latérales du carter. Le volet est positionné verticalement dans sa partie supérieure haute et transversale, ledit volet est aménagé avec une forme (3 a) constituant une barre de renvoi du matériau avec une configuration curviligne pour le passage et le guidage de la bande de matériau en provenance de la partie réceptacle du carter. En variante, comme représenté figure 2, le volet (3) n'est pas agencé directement avec la barre de renvoi mais une barre de renvoi indépendante (4) est rapportée et fixée au-dessus dudit volet avec la forme curviligne décrite précédemment. The apparatus comprises a housing (1) forming a receptacle with a bottom plate (1a), a lower horizontal wall (1b), side walls (1c) with a cover (2) articulated with respect to the housing by a lug assembly or axis (2a) with receiving hole, and this, well known manner. The strip of material is referenced by (B). The lid is raised from the top to close. It further comprises a flap (3) articulated with respect to the two side walls of the casing being detachably fastened by means of clipping pins or locating pins in receiving openings formed on the side walls. crankcase. The shutter is positioned vertically in its upper and transverse upper part, said shutter is arranged with a shape (3 a) constituting a material return bar with a curvilinear configuration for the passage and guiding of the strip of material from the receptacle portion of the housing. In a variant, As shown in Figure 2, the flap (3) is not arranged directly with the return bar but an independent return bar (4) is attached and fixed above said flap with the curvilinear shape described above.
Dans sa partie inférieure, le volet présente une découpe centrale (3b) pour permettre la sortie de la bande de matériau. Le couvercle (2) présente sur sa face inférieure une découpe centrale (2b) identique et en regard de la découpe (3b) dudit volet.  In its lower part, the flap has a central cutout (3b) to allow the exit of the strip of material. The lid (2) has on its underside a central cutout (2b) identical and opposite the cutout (3b) of said shutter.
Selon l'invention, au moins le volet (3) présente autour de sa bordure périphérique (3 c) une forme (3d) ayant une configuration curviligne établie sur tout le pourtour de la bordure périphérique de la découpe (3b). Ladite forme (3d) est établie dans un plan perpendiculaire au plan du volet venant en débordement extérieur de celui-ci pour être en regard du couvercle de fermeture. Cette forme (3d) présente une hauteur différenciée progressive de sa partie centrale (3dl) avec une hauteur la plus faible correspondant à la partie haute de la découpe (3b) et se prolongeant jusqu'à ses extrémités (3d2) avec une hauteur (h2) supérieure à ladite hauteur (hl). Ladite forme (3d) ainsi réalisée a, de ce fait, une configuration en rampe dont la fonction apparaîtra par la suite.  According to the invention, at least the flap (3) has around its peripheral edge (3 c) a shape (3d) having a curvilinear configuration established around the periphery of the peripheral edge of the cutout (3b). Said form (3d) is established in a plane perpendicular to the plane of the flap projecting outside thereof to be opposite the closure lid. This form (3d) has a progressive differentiated height of its central portion (3dl) with a lower height corresponding to the upper part of the cutout (3b) and extending to its ends (3d2) with a height (h2 ) greater than said height (hl). Said form (3d) thus produced has, as a result, a ramp configuration whose function will appear thereafter.
Les extrémités (3d2) de la rampe font saillies et viennent en regard de la ligne de prédécoupe de la bande de matériau pour permettre l'amorce de déchirement transversal pour l'obtention d'un format de bande de matériau. Comme représenté figure 5, lesdites extrémités (3d2) débordent sensiblement de la face apparente extérieure du couvercle. A titre indicatif, la hauteur (hl) est de quelques millimètres, trois à cinq millimètres environ, et la hauteur (h2) aux extrémités (3d2) est de l'ordre de six à quinze millimètres. L'arête desdites extrémités (3d2) est, soit pointue, soit effilée et arrondie de préférence, pour éviter toute blessure.  The ends (3d2) of the ramp protrude and come opposite the precut line of the web of material to allow transverse tear initiation to obtain a material web format. As shown in FIG. 5, said ends (3d2) project substantially beyond the outer apparent face of the cover. As an indication, the height (hl) is a few millimeters, about three to five millimeters, and the height (h2) at the ends (3d2) is of the order of six to fifteen millimeters. The edge of said ends (3d2) is either pointed or tapered and preferably rounded to prevent injury.
Sur le chant de la forme peut être disposée, moulée ou rapportée une garniture en élastomère chevauchant le chant pour assurer une fonction de freinage du matériau et permettant l'étirement des points de prédécoupe sur la ligne de prédécoupe. On the edge of the shape can be arranged, molded or attached an elastomeric seal overlapping the edge to provide a function of braking of the material and allowing the stretching of the precut points on the precut line.
En d'autres termes, si l'on fait référence aux dessins, après fermeture du couvercle sur le carter, la bande de matériau se présente entre le volet et le couvercle en glissant sur la forme (3d) constituant rampe dans un premier temps par la partie centrale de faible hauteur (hl) puis se déplace, de par la traction par l'utilisateur, le long de la forme (3d) jusqu'à atteindre les extrémités (3d2) avec la hauteur (h2). A ce moment, la ligne de prédécoupe de la bande de matériau atteint lesdites extrémités (3d2) de la forme (3d), lesquelles pénètrent dans le matériau en permettant ensuite le déchirement transversal complet de la bande de matériau selon un format donné.  In other words, if reference is made to the drawings, after closure of the cover on the casing, the strip of material is between the flap and the cover by sliding on the form (3d) constituting ramp in a first step by the central part of low height (hl) then moves, by the traction by the user, along the form (3d) until reaching the ends (3d2) with the height (h2). At this time, the precut line of the web of material reaches said ends (3d2) of the shape (3d), which penetrate into the material and then allow complete transverse tearing of the web of material in a given format.
En pratique, on a un double effet, à savoir une tension de la bande de matériau qui est sur le pourtour périphérique de l'ouverture centrale (3b) et de la forme (3d) qui, en combinaison avec la pente de la rampe et la sortie des extrémités (3d) de la forme dans le matériau, permet la séparation d'un format de bande de matériau.  In practice, there is a double effect, namely a tension of the strip of material which is on the peripheral periphery of the central opening (3b) and the shape (3d) which, in combination with the slope of the ramp and the exit of the ends (3d) of the shape in the material, allows the separation of a material strip format.
La forme (3d) associée à la découpe centrale (3b) du volet octroie à celle-ci une fonction nouvelle, à savoir une fonction de coupe. En quelque sorte, la découpe centrale (3b) ainsi conçue avec la forme (3d) crée une « ouverture distributive » de la bande de matériau. Il s'agit donc d'une conception tout à fait nouvelle et différente de l'art antérieur rappelé au préambule de la présente demande.  The shape (3d) associated with the central cutout (3b) of the shutter gives it a new function, namely a cutting function. In a way, the central cut (3b) thus designed with the shape (3d) creates a "distributive opening" of the web of material. This is therefore a completely new design and different from the prior art recalled in the preamble of the present application.
A titre complémentaire, le couvercle (2) peut être réalisé en combinaison avec le volet (3) précité selon différents agencements.  In addition, the cover (2) can be made in combination with the aforementioned flap (3) according to different arrangements.
Dans une première réalisation, le couvercle (2) présente une face intérieure lisse et plate sans adjonction de moyens supplémentaires autour de sa découpe centrale (2b) qui a la même configuration et forme que la découpe (3b) du volet (3). Ceci est représenté figure 2. Selon les tests effectués par le Demandeur, la bande de matériau prédécoupé, en particulier en matériau d'essuyage, est parfaitement séparée en format par l'action de la forme (3d) et de ses parties d'extrémité (3d2). In a first embodiment, the cover (2) has a smooth and flat inner face without additional means added around its central cutout (2b) which has the same configuration and shape as the cutout (3b) of the shutter (3). This is shown in FIG. 2. According to the tests carried out by the Applicant, the strip of pre-cut material, in particular in wiping material, is perfectly separated in format by the action of the form (3d) and its end portions (3d2).
Dans une seconde réalisation représentée aux figures 6, 7 notamment, le couvercle (2) est agencé avec une contre-forme (2c) disposée autour de l'ouverture centrale (2b) directement moulée ou rapportée sur la face intérieure du couvercle. Cette contre-forme (2c) peut présenter une hauteur (h3) régulière et constante sur toute sa longueur.  In a second embodiment shown in Figures 6, 7 in particular, the cover (2) is arranged with a counter-shape (2c) disposed around the central opening (2b) directly molded or attached to the inner face of the cover. This counter-form (2c) may have a height (h3) regular and constant over its entire length.
Lors de la fermeture du couvercle (2) sur le carter, ladite contre-forme (2c) vient entourer la forme (3d) dudit volet (3) tout en laissant un léger passage pour la bande de matériau.  When closing the lid (2) on the housing, said against-shape (2c) surrounds the shape (3d) of said flap (3) while leaving a slight passage for the material strip.
Dans une variante de réalisation, figures 17 et 18, la contre-forme (2c) peut être conçue de manière similaire à la forme (3d) du volet. Elle présente une hauteur progressive de sa partie centrale (2c 1) à ses extrémités (2c2) avec respectivement les hauteurs (h3) et (h4). La hauteur (h4) est supérieure à la hauteur (h3). Ainsi, on obtient des saillies complémentaires en extrémité qui sont plus particulièrement utiles pour la distribution de matériaux d'essuyage épais et de matériaux non-tissés qui se trouvent à l'opposé des extrémités (3d2) de la forme (3d) après fermeture du couvercle.  In an alternative embodiment, FIGS. 17 and 18, the counterform (2c) may be designed similarly to the form (3d) of the shutter. It has a progressive height of its central part (2c 1) at its ends (2c2) with respectively the heights (h3) and (h4). The height (h4) is greater than the height (h3). Thus, complementary end protrusions are obtained which are more particularly useful for dispensing thick wiping materials and nonwoven materials which are opposite ends (3d2) of the form (3d) after closing. lid.
Comme indiqué précédemment, la forme (3d) sur le volet, et la contre - forme (2c) sur le couvercle, sont directement moulées avec eux. On obtient ainsi appareil avec seulement trois ou quatre composants, le carter, le volet, le couvercle et la barre de renvoi si elle est indépendante du volet, ceci sans autres pièces et composants accessoires.  As indicated above, the form (3d) on the shutter, and the counterform (2c) on the lid, are directly molded with them. This gives the appliance with only three or four components, the housing, the flap, the cover and the return bar if it is independent of the shutter, this without other parts and accessory components.
Comme représenté à titre d'exemple aux figures 10 à 17, la forme (3d) sur le volet (3) et la contre-forme (2c) peuvent aussi être rapportées. Dans ce cas, elles présentent respectivement un talon (3e)(2d) de configuration curviligne en étant fixées de toute manière appropriée. Dans ce cas, la forme et la contre-forme peuvent être dans un même matériau que le volet et le couvercle ou en un matériau différent. Dans cette mise en œuvre, on obtient ainsi un jeu de formes (3d) et de contre-formes (2c) qui permettent d'adapter l'appareil distributeur à la nature du matériau prédécoupé à distribuer. As shown by way of example in FIGS. 10 to 17, the shape (3d) on the shutter (3) and the counterform (2c) can also be reported. In this case, they respectively have a heel (3e) (2d) curvilinear configuration being fixed in any appropriate manner. In this case, the shape and the counter-form may be in the same material as the shutter and the cover or in a different material. In this implementation, we obtain and a set of shapes (3d) and counterforms (2c) that adapt the dispenser device to the nature of the pre-cut material to be dispensed.
L'invention offre un nouveau concept d'appareil distributeur de matériau prédécoupé enroulé en bobine ou plié en « Z ». Elle octroie une fonction nouvelle à la ou aux deux ouverture(s) établie(s) sur le volet et le couvercle, à savoir une fonction de coupe du matériau.  The invention offers a new concept of dispensing apparatus of pre-cut material wound in a coil or folded in "Z". It grants a new function to the one or both opening (s) established (s) on the shutter and the cover, namely a cutting function of the material.
En outre, ce nouvel agencement de l'appareil permet à l'ouverture formée sur le volet et dans les différentes variantes en combinaison avec l'ouverture formée sur le couvercle d'assurer quatre fonctions :  In addition, this new arrangement of the apparatus allows the opening formed on the shutter and in the various variants in combination with the opening formed on the lid to provide four functions:
• Meilleure présentation du matériau qui n'est pas froissé en sortie de l'appareil en venant se présenter au droit et sans débordement de la partie inférieure de l'appareil. • Better presentation of the material that is not wrinkled at the exit of the device coming to appear to the right and without overflow of the lower part of the apparatus.
• Préhension aisée de la bande de matériau, • Easy gripping of the web of material,
• Ecartement diamétral avec mise en tension de la bande autour de l'ouverture centrale combiné avec l'effet rampe et hauteur maximum de la forme en sortie de matériau permettant l'étirement des points de prédécoupe de la ligne de prédécoupe, • Diametral spacing with tensioning of the band around the central opening combined with the ramp effect and maximum height of the material outlet shape allowing the stretching of the precut points of the precut line to be stretched,
• Séparation des formats. • Separation of formats.
Toute la distribution et la coupe de la bande de matériau s'effectue dans l'espace de l'ouverture (3b) du volet. Il est ainsi possible d'avoir un appareil compact et économique. Aucune pièce n'est en mouvement, il n'y a aucun problème de maintenance. The entire distribution and cutting of the strip of material takes place in the space of the opening (3b) of the flap. It is thus possible to have a compact and economical device. No parts are moving, there is no maintenance problem.
L'appareil ainsi réalisé permet la distribution de tous matériaux souples prédécoupés, matériaux d'essuyage en papiers, non tissés. The apparatus thus produced allows the distribution of all pre-cut flexible materials, paper wiping materials, nonwovens.
