Description

La présente invention s'inscrit dans le domaine de la distribution de consommables sous forme de rouleaux de papier, du type rouleau essuie-main, rouleau essuie-tout, rouleau de papier toilette, etc.The present invention falls within the field of distribution of consumables in the form of paper rolls, such as hand towel rolls, paper towel rolls, toilet paper rolls, etc.

La présente invention a trait plus précisément à un dévidoir de rouleau de papier, à un embout détrompeur pour rouleau de papier destiné à être dévidé et à un ensemble comportant un rouleau de papier, l'embout détrompeur selon l'invention et le dévidoir selon l'invention.The present invention relates more specifically to a paper roll dispenser, a keying tip for a paper roll intended to be unwound, and an assembly comprising a paper roll, the keying tip according to the invention, and the dispenser according to the invention.

De façon connue, un rouleau de papier, du type rouleau essuie-main, rouleau essuie-tout, rouleau de papier toilette, comporte généralement une pluralité de feuilles de papier reliées entre elles de façon sécables, enroulées sur un tube comportant un évidement axial qui s'étend sur toute la longueur du tube.As is known, a roll of paper, such as a hand towel roll, paper towel roll, or toilet paper roll, generally consists of a plurality of sheets of paper linked together in a breakable manner, wound on a tube having an axial recess that extends along the entire length of the tube.

L'évidement axial du tube permet le montage du rouleau de papier sur un dévidoir de rouleau de papier.The axial recess in the tube allows the paper roll to be mounted on a paper roll dispenser.

Les dévidoirs de rouleau de papier sont largement utilisés chez les particuliers et chez les professionnels, par exemple au sein de locaux professionnels accueillant ou non du public.Paper roll dispensers are widely used by individuals and professionals, for example in professional premises open to the public or not.

Il est fréquent que les sociétés qui installent des dévidoirs de rouleaux de papier chez les professionnels proposent à leurs clients la fourniture et la pose d'un ou plusieurs dévidoirs à titre gracieux, en échange de la vente d'un contrat d'approvisionnement exclusif en rouleaux de papier par la société qui a fourni et installé le dévidoir.It is common for companies that install paper roll dispensers for professionals to offer their clients the supply and installation of one or more dispensers free of charge, in exchange for the sale of an exclusive paper roll supply contract by the company that supplied and installed the dispenser.

Les sociétés proposant ce type de service équipent généralement de façon connue les rouleaux de papier et les dévidoirs d'un dispositif anti-fraude consistant de façon connue en un détrompeur, ceci afin d'éviter qu'un client n'utilise sur le dévidoir un rouleau de papier qui n'est pas celui commercialisé par la société qui a installé le dévidoir.Companies offering this type of service generally equip paper rolls and dispensers with a known anti-fraud device consisting of a known error-proof device, in order to prevent a customer from using on the dispenser a roll of paper that is not the one marketed by the company that installed the dispenser.

Selon une réalisation de l'art antérieur, un détrompeur comporte une fixée à l'intérieur de l'évidement axial pratiqué dans le rouleau et présentant un embout mâle proéminent depuis une extrémité du tube du rouleau, l'embout mâle étant apte à coopérer avec un embout femelle du dévidoir, généralement monté sur un bras du dévidoir.According to a prior art embodiment, a keying device comprises a fixed inside the axial recess made in the roller and having a male end protruding from one end of the roller tube, the male end being able to cooperate with a female end of the reel, usually mounted on an arm of the reel.

Le document US 2007/075180 A1 propose un rouleau de papier, une douille pour un rouleau de papier et une combinaison d'un rouleau de papier avec un distributeur. Le rouleau de papier comprend un noyau de rouleau de papier creux avec deux extrémités opposées. La douille a un corps cylindrique emboîté par pression dans au moins une des extrémités du noyau du rouleau de papier et la douille comprend en outre une paroi d'extrémité circulaire fixée de manière frangible à une première extrémité du corps et fermant l'extrémité du noyau du rouleau de papier. La paroi d'extrémité est pourvue d'un trou central de réception de broches. La paroi d'extrémité est conçue pour se rompre lors du retrait du rouleau de papier du distributeur. Ainsi, la douille ne peut pas être réutilisée.The document US 2007/075180 A1 offers a paper roll, a paper roll holder, and a paper roll combination with a dispenser. The paper roll dispenser comprises a hollow paper roll core with two opposing ends. The sleeve has a cylindrical body that is press-fitted into at least one end of the paper roll core. The sleeve further comprises a circular end wall that is frangibly attached to one end of the body and closes off the end of the paper roll core. The end wall has a central hole for receiving pins. The end wall is designed to break when the paper roll is removed from the dispenser. Therefore, the sleeve cannot be reused.

La coopération entre les embouts mâle et femelle est telle qu'un seul type de rouleau de papier, celui autorisé par le fabricant qui a installé le dévidoir, peut être utilisé avec le dévidoir.The cooperation between the male and female ends is such that only one type of paper roll, the one authorized by the manufacturer who installed the dispenser, can be used with the dispenser.

Si cela permet au fabricant de s'assurer que le client n'utilise effectivement que le type de rouleau de papier objet du contrat, il est fréquent que la protubérance mâle, dont sa face de coopération s'étend à l'extérieur de l'évidement axial pratiqué dans le tube, se rompe, notamment lors du transport ou du stockage du rouleau de papier.While this allows the manufacturer to ensure that the customer actually uses only the type of paper roll covered by the contract, it is common for the male protrusion, whose cooperating face extends outside the axial recess made in the tube, to break, particularly during transport or storage of the paper roll.

L'objet de la présente invention vise à pallier les inconvénients ci-dessus tout en empêchant l'installation sur un dévidoir d'un rouleau de papier non autorisé.The object of the present invention is to overcome the above disadvantages while preventing the installation on a dispenser of an unauthorized roll of paper.

La présente invention concerne un ensemble selon la revendication 1.The present invention relates to an assembly according to claim 1.

Ainsi, en prévoyant un dévidoir dont le détrompeur comporte une face de coopération prévue pour pénétrer au moins partiellement à l'intérieur de l'évidement axial du tube du rouleau lorsque le rouleau est supporté par le plot de support et par le détrompeur du dévidoir, il est possible de monter dans le dévidoir un rouleau de papier équipé d'un embout détrompeur dont sa face de coopération est avantageusement agencée à l'intérieur de l'évidement axial du tube du rouleau, ce qui permet de s'affranchir de la présence de protubérance mâle présentant comme c'est le cas dans l'art antérieur une face de coopération qui s'étend à l'extérieur de l'évidement axial pratiqué dans le tube. Cela permet avantageusement de pallier l'inconvénient lié au risque de casse de cette protubérance pouvant survenir lors du transport ou du stockage du rouleau de papier. Selon des caractéristiques de l'ensemble de l'invention, le dévidoir comporte un bord supérieur et un bord inférieur, le détrompeur étant positionné entre lesdits bords supérieur et inférieur, et :

  • le détrompeur comporte une coupelle comportant une paroi externe tronconique glissante agencée en périphérie de la face de coopération dudit détrompeur, définissant une pente orientée vers ledit bord inférieur du dévidoir, de façon à entraîner ledit rouleau en direction dudit bord inférieur lorsque ledit rouleau est monté dans le dévidoir et lorsque ledit rouleau ne comporte pas d'embout détrompeur ou lorsque l'embout détrompeur dudit rouleau ne coopère pas avec la face de coopération du détrompeur, et
  • le dispositif anti-fraude comporte au moins un redent de blocage, monté sur le bord inférieur du dévidoir, s'étendant en direction du détrompeur et étant agencé de façon à exercer une force de frottement contre une paroi inférieure du rouleau de papier après que ledit rouleau a été entraîné en direction dudit bord inférieur par ladite coupelle.
Thus, by designing a dispenser with a keying feature that has a cooperating face intended to penetrate at least partially into the axial recess of the roll tube when the roll is supported by the support block and the dispenser's keying feature, it is possible to mount a paper roll equipped with a keying tip in the dispenser. The cooperating face of this tip is advantageously positioned inside the axial recess of the roll tube, eliminating the need for a male protrusion, as found in the prior art, which has a cooperating face extending outside the axial recess in the tube. This advantageously overcomes the drawback of the risk of breakage of this protrusion during the transport or storage of the paper roll. According to features of the invention as a whole, the reel comprises an upper edge and a lower edge, the keying device being positioned between said upper and lower edges, and:
  • The locating device comprises a cup having a sliding frustoconical outer wall arranged around the periphery of the cooperating face of said locating device, defining a slope oriented towards said lower edge of the reel, so as to drive said roller towards said lower edge when said roller is mounted in the reel and when said roller does not have a locating tip or when the alignment end of said roller does not cooperate with the cooperation face of the alignment device, and
  • the anti-fraud device includes at least one locking tooth, mounted on the lower edge of the dispenser, extending towards the keying device and arranged to exert a frictional force against a lower wall of the paper roll after said roll has been driven towards said lower edge by said cup.

Grâce à cette configuration, on empêche la rotation du rouleau de papier lorsque le rouleau ne comporte pas d'embout détrompeur ou lorsque l'embout détrompeur du rouleau ne coopère pas avec la face de coopération du détrompeur. On réduit ainsi considérablement le risque d'utilisation frauduleuse du dévidoir.This design prevents the paper roll from rotating when the roll lacks a keying feature or when the keying feature on the roll does not align with the keying face. This significantly reduces the risk of fraudulent use of the paper dispenser.

Selon des caractéristiques optionnelles de l'ensemble de l'invention :

Sur l'ensemble des figures, des références identiques ou analogues représentent des organes ou ensembles d'organes identiques ou analogues.Throughout the figures, identical or analogous references represent identical or analogous organs or sets of organs.

On se réfère aux figures 1 et 2 illustrant respectivement le dévidoir 1 selon l'invention et un rouleau 3 de papier destiné à être dévidé.We refer to figures 1 and 2 illustrating respectively the dispenser 1 according to the invention and a roll 3 of paper intended to be unwound.

Le dévidoir 1 comporte un carter 5 comportant une face arrière 7 pouvant être accrochée à un mur ou à un support mural par l'intermédiaire d'encoches 9. Le carter 5 comporte également une face avant qui a été retirée de la figure 1 pour une meilleure visibilité.The reel 1 comprises a housing 5 having a rear face 7 that can be hung on a wall or wall bracket by means of notches 9. The housing 5 also comprises a front face which has been removed from the figure 1 for better visibility.

Le dévidoir 1 comporte un bord supérieur 11 et un bord inférieur 13. Le dévidoir 1 comporte une base de support 15 montée au niveau du bord inférieur 13 du dévidoir 1. La base de support 15 adopte à titre d'exemple une forme parallélépipédique présentant une paroi supérieure 17, par exemple plane.The reel 1 has an upper edge 11 and a lower edge 13. The reel 1 has a support base 15 mounted at the lower edge 13 of the reel 1. The support base 15 adopts, for example, a parallelepiped shape having an upper wall 17, for example flat.

Le dévidoir 1 comporte deux bras de support 19, 21 comportant chacun une première extrémité 19a, 21a et une deuxième extrémité 19b, 21b.The reel 1 has two support arms 19, 21 each having a first end 19a, 21a and a second end 19b, 21b.

Les premières extrémités 19a, 21a des bras 19, 21 sont montées sur la paroi supérieure 17 de la base de support 15.The first ends 19a, 21a of the arms 19, 21 are mounted on the upper wall 17 of the support base 15.

Le dévidoir 1 comporte par ailleurs un plot de support 23 conçu et agencé dans le dévidoir pour supporter une première extrémité 25 du rouleau 3 de papier destiné à être dévidé (visible à la figure 2).The dispenser 1 also includes a support block 23 designed and arranged in the dispenser to support a first end 25 of the roll 3 of paper intended to be unwound (visible at the figure 2 ).

Le plot de support 23 est monté au niveau de la deuxième extrémité 19b du bras 19. Le dévidoir 1 comporte en outre un dispositif anti-fraude 27 mis en œuvre dans le dévidoir pour empêcher l'utilisation d'un rouleau de papier qui n'est pas conforme à celui autorisé par l'installateur du dévidoir.The support block 23 is mounted at the second end 19b of the arm 19. The dispenser 1 also includes an anti-fraud device 27 implemented in the dispenser to prevent the use of a roll of paper that does not conform to that authorized by the installer of the dispenser.

Le dispositif anti-fraude 27 comporte un détrompeur 29 monté en regard du plot de support 23, qui est conçu et agencé dans le dévidoir 1 pour supporter une deuxième extrémité 31 du rouleau 3 de papier destiné à être dévidé (visible à la figure 2).The anti-fraud device 27 includes a keying device 29 mounted opposite the support block 23, which is designed and arranged in the dispenser 1 to support a second end 31 of the roll 3 of paper intended to be unwound (visible at the figure 2 ).

Le détrompeur 29 est monté au niveau de la deuxième extrémité 21b du bras 21.The keying device 29 is mounted at the second end 21b of the arm 21.

Le détrompeur 29 et le plot de support 23 sont conçus et agencés dans le dévidoir pour supporter le rouleau 3 destiné à être dévidé et pour permettre sa rotation sur un axe de rotation 33 passant par le plot de support 23 et par le détrompeur 29 lorsque le rouleau 3 est monté sur le dévidoir 1.The keying device 29 and the support block 23 are designed and arranged in the reel to support the roll 3 intended to be unwound and to allow its rotation on a rotation axis 33 passing through the support block 23 and through the keying device 29 when the roll 3 is mounted on the reel 1.

Selon une variante de réalisation non représentée, le plot de support 23 et le détrompeur 29 sont respectivement montés sur les bras 19, 21 à un emplacement distinct des deuxièmes extrémités 19b, 21b, par exemple au milieu des bras 19, 21. Selon une autre variante non représentée aux figures, le dévidoir 1 comporte un carter 5 sur la face intérieure duquel sont directement montés le plot de support 23 et le détrompeur 29. Selon cette forme de réalisation, le dévidoir 1 peut ne pas comporter de bras de support et de base de support.According to an alternative embodiment not shown, the support block 23 and the keying device 29 are respectively mounted on the arms 19, 21 at a location distinct from the second ends 19b, 21b, for example in the middle of the arms 19, 21. According to another alternative embodiment not shown in the figures, the reel 1 has a housing 5 on the inner face of which the support block 23 and the keying device 29 are directly mounted. According to this embodiment, the reel 1 may not have support arms and a support base.

En référence à la figure 2, le rouleau 3 de papier comporte un tube 35 comportant un évidement axial 37 qui s'étend sur toute la longueur du tube 35, sur lequel est enroulée une pluralité de feuilles de papier 39 reliées entre elles de façon sécables. Le rouleau 3 de papier est du type rouleau essuie-main, rouleau essuie-tout, rouleau de papier toilette, etc. L'évidement axial 37 du tube 35 permet le montage du rouleau 3 de papier sur le plot de support 23 et sur le détrompeur 29, grâce à un embout détrompeur détaillé dans la suite de la description.With reference to the figure 2 The paper roll 3 comprises a tube 35 having an axial recess 37 extending along the entire length of the tube 35, around which are wound a plurality of paper sheets 39 joined together in a separable manner. The paper roll 3 is of the hand towel roll type, paper towel roll, toilet paper roll, etc. The axial recess 37 of the tube 35 allows the paper roll 3 to be mounted on the support block 23 and on the keying device 29, thanks to a keying tip detailed later in the description.

On se réfère aux figures 3 à 5 illustrant respectivement le dévidoir 1 en coupe longitudinale partielle centrée sur les bras de support 19, 21, le dévidoir sur lequel est monté le rouleau 3 de papier destiné à être dévidé et le rouleau 3 de papier recevant un embout détrompeur selon l'invention.We refer to figures 3 to 5 illustrating respectively the dispenser 1 in partial longitudinal section centered on the support arms 19, 21, the dispenser on which is mounted the roll 3 of paper intended to be unwound and the roll 3 of paper receiving a keying tip according to the invention.

Le plot de support 23 comporte une face de support 41 qui pénètre dans l'évidement axial 37 du tube 35 du rouleau de papier 3.The support block 23 has a support face 41 which penetrates the axial recess 37 of the tube 35 of the paper roll 3.

De façon connue, la face de support comporte une portion tronconique 43 recevant en son extrémité un épaulement 45 prévu pour pénétrer à l'intérieur de l'évidement axial 37 du tube 35 du rouleau de papier 3, de sorte que l'extrémité 25 du rouleau 3 est supporté par la face de support 41 du plot de support 23.In a known manner, the support face has a frustoconical portion 43 receiving at its end a shoulder 45 intended to penetrate inside the axial recess 37 of the tube 35 of the paper roll 3, so that the end 25 of the roll 3 is supported by the support face 41 of the support block 23.

Le détrompeur 29 comporte quant à lui une face de coopération 47 destinée à coopérer avec un embout détrompeur 49 fixé sur le rouleau 3 de papier destiné à être dévidé lorsque le rouleau est monté dans le dévidoir 1.The keying device 29 has a cooperation face 47 intended to cooperate with a keying tip 49 fixed on the roll 3 of paper intended to be unwound when the roll is mounted in the unwinder 1.

Selon l'invention, la face de coopération du détrompeur est prévue pour pénétrer au moins partiellement à l'intérieur de l'évidement axial 37 du tube 35 du rouleau 3 lorsque le rouleau est supporté par le plot de support 23 et par le détrompeur 29.According to the invention, the cooperation face of the keying device is provided to penetrate at least partially into the axial recess 37 of the tube 35 of the roller 3 when the roller is supported by the support block 23 and by the keying device 29.

Ainsi, la face de coopération 51 de l'embout détrompeur 49 du rouleau 3 est avantageusement agencée à l'intérieur de l'évidement axial 37 du tube du rouleau, ce qui permet de s'affranchir de la présence de protubérance mâle présentant comme c'est le cas dans l'art antérieur une face de coopération qui s'étend à l'extérieur de l'évidement axial pratiqué dans le tube. Cela permet avantageusement de pallier l'inconvénient lié au risque de casse de cette protubérance pouvant survenir lors du transport ou du stockage du rouleau de papier. En effet, comme illustré à la figure 5, lorsque l'embout détrompeur 49 est fixé sur le rouleau 3, par exemple à des fins de stockage ou de transport du rouleau, la face de coopération 51 de l'embout détrompeur pénètre à l'intérieur de l'évidement axial 37 du tube 35 du rouleau.Thus, the cooperation face 51 of the keying tip 49 of the roller 3 is advantageously arranged inside the axial recess 37 of the roller tube, thereby eliminating the need for a male protrusion which, as in the prior art, has a cooperation face extending outside the axial recess in the tube. This advantageously overcomes the drawback of the risk of breakage of this protrusion during the transport or storage of the paper roll. Indeed, as illustrated in the figure 5 , when the keying tip 49 is fixed on the roller 3, for example for the purpose of storing or transporting the roller, the cooperation face 51 of the keying tip enters the inside of the axial recess 37 of the tube 35 of the roller.

La coopération entre le détrompeur 29 du dévidoir et l'embout détrompeur 49 du rouleau 3 de papier est, selon une réalisation, assurée en prévoyant un plot détrompeur mâle 53 sur le détrompeur 49, prévu pour pénétrer un plot détrompeur femelle 55 agencé sur l'embout détrompeur 49 fixé sur le rouleau 3 lorsque le rouleau est monté dans le dévidoir 1.The cooperation between the 29 of the dispenser and the 49 of the paper roll 3 is, according to one embodiment, ensured by providing a male 53 of the 49 of the dispenser, intended to penetrate a female 55 of the 49 of the dispenser arranged on the 3 of the paper roll when the roll is mounted in the dispenser 1.

On se réfère aux figures 6 et 7 illustrant l'embout détrompeur respectivement en vue isométrique et en coupe longitudinale selon la ligne VII-VII.We refer to figures 6 and 7 illustrating the keying tip respectively in isometric view and in longitudinal section along line VII-VII.

L'embout détrompeur 49 comporte une coupelle 57 comportant une paroi externe 58 tronconique recevant concentriquement le plot détrompeur femelle 55. Selon une variante non représentée, la paroi externe 58 de la coupelle 57 adopte une forme cylindrique plutôt que tronconique.The keying tip 49 includes a cup 57 having an external wall 58 frustoconical receiving concentrically the female keying pin 55. According to an unrepresented variant, the external wall 58 of the cup 57 adopts a cylindrical rather than frustoconical shape.

Le plot détrompeur femelle 55 présente une paroi externe 59 tronconique prolongée par un bord extérieur 61 lui-même prolongé par une cavité 63 dont le bord intérieur définit une butée 65 à l'intérieur de laquelle est reçu le plot détrompeur mâle 53 du détrompeur 29 du dévidoir 1. Selon une variante non représentée, la paroi externe 59 du plot détrompeur femelle 55 adopte une forme cylindrique plutôt que tronconique. Selon une réalisation, l'embout détrompeur 49 comporte un épaulement 67 qui s'étend radialement vers l'extérieur de la coupelle 57 depuis l'axe de révolution 69 de l'embout détrompeur 49. L'épaulement est conformé pour définir une surface d'appui contre une paroi latérale 71 (visible à la figure 5) du rouleau 3 de papier lorsque l'embout détrompeur 49 est monté dans l'évidement axial 37 du tube 35 du rouleau 3. La présence de l'épaulement 67 permet de bloquer l'embout détrompeur 49 en translation le long de l'évidement 37 du tube 35.The female keying pin 55 has a frustoconical outer wall 59 extended by an outer edge 61, itself extended by a cavity 63 whose inner edge defines a stop 65 inside which the male keying pin 53 of the key 29 of the reel 1 is received. According to an unshown variant, the outer wall 59 of the female keying pin 55 is cylindrical rather than frustoconical. In one embodiment, the keying tip 49 has a shoulder 67 that extends radially outwards from the cup 57 from the axis of revolution 69 of the keying tip 49. The shoulder is shaped to define a bearing surface against a lateral wall 71 (visible in the figure 5 ) of the paper roll 3 when the keying tip 49 is mounted in the axial recess 37 of the tube 35 of the roll 3. The presence of the shoulder 67 allows the keying tip 49 to be locked in translation along the recess 37 of the tube 35.

L'embout détrompeur 49 peut avantageusement être obtenu en matériau biodégradable tel que de la cellulose.The 49 anti-missing tip can advantageously be made from biodegradable material such as cellulose.

On se réfère à la figure 8 qui est un agrandissement de la zone VIII de la figure 4.We refer to the figure 8 which is an expansion of zone VIII of the figure 4 .

L'ensemble formé par la paroi externe 59 du plot détrompeur femelle 55, par les bords extérieurs 61 du plot détrompeur femelle 55 et par la cavité 63 du plot détrompeur femelle 55 définit la face de coopération 51 de l'embout détrompeur 49.The assembly formed by the outer wall 59 of the female keying stud 55, by the outer edges 61 of the female keying stud 55 and by the cavity 63 of the female keying stud 55 defines the cooperation face 51 of the keying tip 49.

La face de coopération 51 présente une géométrie complémentaire de celle de la face de coopération 47 du détrompeur 29 du dévidoir 1.The cooperation face 51 has a geometry complementary to that of the cooperation face 47 of the ripping device 29 of the reel 1.

A cet effet, le plot détrompeur mâle 53 du détrompeur 29 présente une paroi externe 73 tronconique prolongée au niveau de sa première extrémité par un bord extérieur 75 coopérant avec la cavité 63 du plot détrompeur femelle 55 de l'embout détrompeur 49 et au niveau de sa deuxième extrémité par deux cavités 77, 79 dont les bords intérieurs définissent deux butées 81, 83 à l'intérieur desquelles sont reçus les bords extérieurs 61 du plot détrompeur femelle 55 de l'embout détrompeur 49. Les cavités 77, 79 sont elles-mêmes prolongées par un bord de liaison 85 assurant la liaison avec une coupelle 87 agencée en périphérie de la face de coopération 47.To this end, the male locating pin 53 of the locating pin 29 has a frustoconical outer wall 73 extended at its first end by an outer edge 75 cooperating with the cavity 63 of the female locating pin 55 of the locating tip 49 and at its second end by two cavities 77, 79 whose inner edges define two stops 81, 83 inside which the outer edges 61 of the female locating pin 55 of the locating tip 49 are received. The cavities 77, 79 are themselves extended by a connecting edge 85 ensuring the connection with a cup 87 arranged at the periphery of the cooperation face 47.

Selon une variante non représentée, la paroi externe 73 du plot détrompeur mâle 53 adopte une forme cylindrique plutôt que tronconique.According to an unrepresented variant, the outer wall 73 of the male keying stud 53 adopts a cylindrical rather than a frustoconical shape.

L'ensemble formé par le bord de liaison 85, par les cavités 77, 79, par la paroi externe 73 du plot détrompeur mâle 53 et par le bord extérieur 75 du plot détrompeur mâle 53 définit la face de coopération 47 du détrompeur 29 du dévidoir 1 dont sa géométrie est complémentaire à celle de la face de coopération 51 de l'embout détrompeur 49 du rouleau 3 de papier.The assembly formed by the connecting edge 85, by the cavities 77, 79, by the external wall 73 of the male keying stud 53 and by the external edge 75 of the male keying stud 53 defines the cooperation face 47 of the keying 29 of the dispenser 1 whose geometry is complementary to that of the cooperation face 51 of the keying tip 49 of the paper roll 3.

On se réfère à la figure 9 illustrant une situation où l'on a monté sur le dévidoir 1 de l'invention un rouleau de papier non conforme.We refer to the figure 9 illustrating a situation where a roll of non-conforming paper has been mounted on the dispenser 1 of the invention.

On entend par l'expression « non conforme » un rouleau de papier qui ne comporte pas d'embout détrompeur ou un rouleau de papier dont la face de coopération de l'embout détrompeur du rouleau n'est pas conformée pour coopérer avec la face de coopération du détrompeur du dévidoir.The term "non-compliant" refers to a roll of paper that does not have a keying tip or a roll of paper whose cooperation face of the keying tip of the roll is not shaped to cooperate with the cooperation face of the keying tip of the dispenser.

Afin d'empêcher qu'un utilisateur ne parvienne à utiliser un rouleau de papier non conforme au dévidoir, la coupelle 87 agencée en périphérie de la face de coopération 47 du détrompeur 29. La coupelle 87 comporte une paroi externe 89 tronconique définissant une pente orientée vers le bord inférieur du dévidoir. La paroi externe 89 tronconique est réalisée dans un matériau glissant choisi de sorte que si un rouleau non conforme est monté sur le détrompeur, la force de frottement résultant du contact entre l'évidement 37 du tube 35 du rouleau 3 et la paroi externe 89 tronconique du détrompeur 29 est telle qu'un déplacement du rouleau 3 vers le bord inférieur du dévidoir est autorisé.To prevent a user from using a non-compliant paper roll on the dispenser, a cup 87 is arranged around the periphery of the cooperation face 47 of the keying device 29. The cup 87 has a frustoconical outer wall 89 defining a slope oriented towards the lower edge of the dispenser. The frustoconical outer wall 89 is made of a sliding material chosen so that if a non-compliant roll is mounted on the keying device, the frictional force resulting from the contact between the recess 37 of the tube 35 of the roll 3 and the frustoconical outer wall 89 of the keying device 29 is such that movement of the roll 3 towards the lower edge of the dispenser is permitted.

En complément de la paroi externe 89 tronconique, le dispositif anti-fraude 27 peut comporter un ou plusieurs redents de blocage 91, montés sur le bord inférieur du dévidoir, pouvant être formé par la base de support 15 du dévidoir.In addition to the truncated conical outer wall 89, the anti-fraud device 27 may include one or more locking teeth 91, mounted on the lower edge of the reel, which may be formed by the support base 15 of the reel.

Les redents de blocage 91 s'étendent depuis le bord inférieur du dévidoir vers le détrompeur 29 et sont agencés de façon à exercer une force de frottement contre une paroi inférieure 93 du rouleau 3 de papier, au niveau de la zone 95 représentée à la figure 9, après qu'un rouleau non conforme a été entraîné en direction du bord inférieur 13 du dévidoir par la coupelle 87.The locking teeth 91 extend from the lower edge of the unwinder towards the locating guide 29 and are arranged to exert a frictional force against a lower wall 93 of the paper roll 3, at the level of the area 95 shown in the figure 9 , after a non-conforming roll was driven towards the lower edge 13 of the reel by the cup 87.

Ainsi, l'utilisation d'un rouleau de papier non conforme est largement détériorée par la présence des redents de blocage 91 qui empêchent la bonne rotation du rouleau de papier non conforme.Thus, the use of a non-conforming paper roll is largely impaired by the presence of the locking teeth 91 which prevent the proper rotation of the non-conforming paper roll.

Selon une disposition complémentaire ou alternative visant encore à empêcher la bonne rotation d'un rouleau de papier non conforme, le dispositif anti-fraude 27 comporte un ou plusieurs tétons de blocage 97 qui sont agencés dans le dévidoir de façon à exercer une force de frottement contre la paroi latérale 71 du rouleau 3 de papier, au niveau de la zone 99 représentée à la figure 9, après qu'un rouleau non conforme a été entraîné en direction du bord inférieur du dévidoir par la coupelle 87. Les tétons de blocage 97 sont montés sur les bras de support 19, 21. Lorsque le dévidoir ne comporte pas de bras de support, les tétons de blocage 97 sont montés directement sur la face intérieure du carter 5.According to a supplementary or alternative arrangement further intended to prevent the proper rotation of a non-conforming paper roll, the anti-fraud device 27 comprises one or more locking lugs 97 which are arranged in the dispenser so as to exert a frictional force against the lateral wall 71 of the paper roll 3, at the level of the area 99 shown in the figure 9 , after a non-conforming roll has been driven towards the lower edge of the reel by the cup 87. The locking pins 97 are mounted on the support arms 19, 21. When the reel does not have support arms, the locking pins 97 are mounted directly on the inner face of the housing 5.

Comme il va de soi, la présente invention ne se limite pas aux seules formes de réalisation de ce dévidoir, de cet embout détrompeur et de cet ensemble comportant le dévidoir et le rouleau de papier équipé de l'embout détrompeur, ci-dessus uniquement à titre d'exemples illustratifs, mais elle embrasse au contraire toutes les variantes faisant intervenir les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention, dont l'étendue est définie par les revendications annexées.As will be understood, the present invention is not limited to the embodiments of this dispenser, this keying tip and this assembly comprising the dispenser and the paper roll equipped with the keying tip, above only by way of illustrative examples, but on the contrary it encompasses all variants involving the technical equivalents of the means described as well as their combinations if these fall within the scope of the invention, the extent of which is defined by the attached claims.
