Definitions

  • the present invention relates to a case, and in particular a case intended to contain and distribute products, such as for example products appearing substantially in the form of a folded sheet, arranged in a stack inside said case.
  • these cases have an opening device comprising a weakening line, for example a pre-cut line, not straight, and an adhesive label.
  • the label generally covers the defined area inside the line of weakness, and slightly protrudes outside of said area.
  • the label When using the case for the first time, the label is removed from the corresponding wall.
  • the label peels off the region of the wall located outside the line of weakness and carries with it the region of the wall located inside the line weakening. This region detaches from the rest of the wall along the line of weakness and then forms a closing and opening valve of a distribution window.
  • the case is closed by re-gluing the label in its initial position, the valve being replaced substantially in the dispensing window.
  • Patent 096/11147 describes such a case intended to contain hygiene products arranged in a stack. Its purpose is to reduce the area of the adhesive label, in order to save on adhesive material. It has a weakening line in the form of a V or portion of a circle, and a label having a substantially similar shape, which covers only the weakening line and the lateral edges on either side thereof. Also known in the prior art Cases of the prior art have in common a number of drawbacks. The most important are discussed below.
  • the opening device is placed substantially in the middle of one of their faces. Gripping the product that appears on top of the stack through the dispensing window is often difficult. We also take the risk of taking at least two products at the same time instead of just one.
  • Known cases generally have a longitudinal weld on one of their faces, like many food packaging. This weld is unsightly and gives the case a utilitarian character, unsuitable in particular for luxury goods, such as wipes impregnated with prestigious perfumes.
  • the cases of the prior art are made from a flexible material which does not have the solidity necessary for certain uses, and risks for example tearing, in particular if the user pulls the label more than expected. by the designer of the case. The label may then come off completely and be difficult to re-stick completely and / or tightly.
  • the traction exerted on the flap may cause a tear along the fold forming the upper edge, in particular when the traction comprises a component parallel to the fold. This then results in a loss of tightness.
  • the upper edge of the wipes is accessible when the case is open, which can lead to the user to remove the wipe not by grasping it by the middle fold, but by grasping it by the upper edge. This improper handling leads to a hygienic defect and a risk of extracting several wipes.
  • the flap can be positioned in an inclined manner, which reduces the sealing of the packaging.
  • the object of the present invention is to provide a case for products which overcomes at least some of the drawbacks of the prior art.
  • the case comprising sealing means and an opening device disposed on one face of the case and formed by an adhesive label and an opening flap surrounded at least partly by a line of weakness.
  • the adhesive label completely covers the opening valve and projects beyond the line of weakness which extends in the vicinity of a stop edge of said face.
  • the weakening line extends to, but does not reach, the vicinity of the upper edge.
  • the notion of neighborhood depends on the size and dimension of the case. It can be considered that the concept of neighborhood is understood, within the meaning of this patent, as a distance less than a few percent, in particular less than 10%, of the dimension parallel to the axis of traction.
  • the concept of "without coming into contact” is understood as preserving a short distance, for example less than a few thousandths, in particular less than 1%, of the dimension parallel to the axis of traction.
  • This solution makes it possible to avoid tearing the case in the event of excessive traction on the closing valve.
  • it reserves an upper zone in which the conditioned article remains maintained, unlike the solutions comprising a sealing strip.
  • the result obtained is a better seal and a resealable opening which prevents the articles from being grabbed by the edge. They can only be entered by the middle corner.
  • the weakening line defines the outline of a dispensing window which is situated so as to preferably overlap an edge of the first product to be dispensed.
  • the user can use a finger to select the first product which appears before taking it easily, by pulling on the central corner. This avoids the difficulties and wasteful
  • the area extending between the ends of the weakening line and the edge of the case has the function of stopping the movement resulting from the pulling on the label. It may be an area belonging to the outer contour of the case, or an area formed back from the outer contour.
  • the weakening line preferably has two ends extending substantially to the stop edge and between which the material of the case forms a line of articulation for the valve.
  • the face carrying the weakening line will be called the front face.
  • the side opposite it will be called the back side.
  • the case is made of plastic material, for example thermoformed or injected, and has a shell forming the rear face of the case and secured to a closure element by welding their free edges respective.
  • Said closure element may consist of a flexible membrane, but advantageously takes the form of a second shell forming the front face of the case.
  • the two shells before being welded, can: be independent and therefore subsequently welded by their four free edges, or
  • the case of one invention can advantageously include a tongue placed in a plane parallel to that formed by the two shells. This tab is useful for handling the case. It can also serve as a support for a possibly hollow body.
  • the case may also include pushing means, intended to facilitate the exit of the products contained in said case.
  • the case is made from a sheet of flexible and impermeable material, for example plastic, folded in half along a fold line so as to form two substantially parallel parts. These two parts are welded together by their respective free edges.
  • the line of weakness is located in the vicinity of the fold line.
  • the stop edge is formed by the fold line.
  • the adhesive label can be arranged so as to overlap the fold line. This arrangement has the advantage of providing a label with very high tensile strength.
  • the fold line is located on the edge opposite the weakening line.
  • the adhesive label can then be placed so that one edge of the label is adjacent to the edge of the case opposite the fold line; this arrangement has the advantage of being economical because it requires little adhesive material.
  • the label can also be formed by a return from the rear part of the case to the front part.
  • This return overlaps the weakening line so as to cover the valve.
  • This return is possibly joined by welding to the edge which borders the weakening line.
  • it is made adhesive after anointing with an adhesive polymer or any other material with adequate adhesive properties.
  • the case is produced from two pieces of plastic material placed in parallel planes, these two parts being welded together by their four respective free edges.
  • the adhesive label is arranged so as to overlap the edge of the case which is adjacent to it.
  • the adhesive label can optionally be secured to the case by welding, for example with the lateral edge which is adjacent to it.
  • the case has two opposite parts, welded together by lateral edges, and the large faces of which are not crossed by any weld line. These remain available, for example to receive a decorative motif or an advertising message.
  • the hygiene products arranged in a stack inside the case are each folded into a number of elementary rectangles and / or squares, one of which constitutes one side of the folded product facing the dispensing window.
  • the article comprising products, such as in particular paper products which are substantially in the form of a sheet such as for example wipes or handkerchiefs, placed in a stack inside the dispensing case having a dispensing window on one of its faces, is characterized in that each product has, on one side facing the dispensing window, a gripping corner situated in the median zone of its front face, and in that that the gripping corner of the first product to be dispensed is positioned opposite the dispensing window of the case.

Description

ETUI POUR PRODUITS TELS QUE DES LINGETTES HUMIDES . CASE FOR PRODUCTS SUCH AS WET WIPES.
La présente invention concerne un étui, et notamment un étui destiné à contenir et distribuer des produits, comme par exemple des produits se présentant sensiblement sous forme de feuille pliée, disposés en pile à l'intérieur dudit étui.The present invention relates to a case, and in particular a case intended to contain and distribute products, such as for example products appearing substantially in the form of a folded sheet, arranged in a stack inside said case.
Elle vise également un article constitué d'un étui contenant de tels produits . On connaît dans l'art antérieur des étuis pour produits d'hygiène réalisés à partir d'un film ou d'une feuille de matière plastique souple qui enveloppe les produits. Ces étuis présentent une soudure longitudinale médiane sur l'une de leurs deux grandes faces, et une soudure le long de chacun des deux bords perpendiculaires à la soudure longitudinale.It also relates to an article consisting of a case containing such products. Are known in the prior art cases for hygiene products made from a film or a sheet of flexible plastic material which envelops the products. These cases have a median longitudinal weld on one of their two large faces, and a weld along each of the two edges perpendicular to the longitudinal weld.
Sensiblement au milieu de l'autre grande face, ces étuis présentent un dispositif d'ouverture comprenant une ligne d'affaiblissement, par exemple une ligne prédécoupée, non rectiligne, et une étiquette adhésive. L ' étiquette recouvre généralement la zone définie à l'intérieur de la ligne d'affaiblissement, et déborde légèrement à l'extérieur de ladite zone.Significantly in the middle of the other large face, these cases have an opening device comprising a weakening line, for example a pre-cut line, not straight, and an adhesive label. The label generally covers the defined area inside the line of weakness, and slightly protrudes outside of said area.
Lors du premier usage de l'étui, on écarte l'étiquette de la paroi correspondante. L'étiquette se décolle de la région de la paroi située à l'extérieur de la ligne d'affaiblissement et entraîne avec elle la région de la paroi située à l'intérieur de la ligne d'affaiblissement. Cette région se détache du reste de la paroi le long de la ligne d'affaiblissement et forme ensuite clapet de fermeture et d'ouverture d'une fenêtre de distribution. On referme l'étui en recollant l'étiquette dans sa position initiale, le clapet se replaçant sensiblement dans la fenêtre de distribution.When using the case for the first time, the label is removed from the corresponding wall. The label peels off the region of the wall located outside the line of weakness and carries with it the region of the wall located inside the line weakening. This region detaches from the rest of the wall along the line of weakness and then forms a closing and opening valve of a distribution window. The case is closed by re-gluing the label in its initial position, the valve being replaced substantially in the dispensing window.
Le brevet 096/11147 décrit un tel étui destiné à contenir des produits d'hygiène disposés en pile. Il a pour objet de réduire la surface de l'étiquette adhésive, afin de faire une économie de matériau adhésif. Il présente une ligne d'affaiblissement en forme de V ou de portion de cercle, et une étiquette ayant une forme sensiblement analogue, qui ne recouvre que la ligne d'affaiblissement et les bordures latérales de part et d'autre de celle-ci. On connaît également dans 1 ' état de la technique Les étuis de l'art antérieur ont en commun un certain nombre d'inconvénients. Les plus importants sont discutés ci-dessous.Patent 096/11147 describes such a case intended to contain hygiene products arranged in a stack. Its purpose is to reduce the area of the adhesive label, in order to save on adhesive material. It has a weakening line in the form of a V or portion of a circle, and a label having a substantially similar shape, which covers only the weakening line and the lateral edges on either side thereof. Also known in the prior art Cases of the prior art have in common a number of drawbacks. The most important are discussed below.
En général le dispositif d'ouverture est placé sensiblement au milieu de l'une de leurs faces. La préhension du produit qui apparaît sur le dessus de la pile à travers la fenêtre de distribution est souvent difficile. On prend aussi le risque de prélever au moins deux produits à la fois au lieu d'un seul. Les étuis connus présentent en général une soudure longitudinale sur une de leurs faces, à l'instar de nombre d'emballages alimentaires. Cette soudure est inesthétique et confère à l'étui un caractère utilitaire, inadapté notamment à des produits du domaine du luxe, comme par exemple des lingettes imprégnées de parfums prestigieux.In general, the opening device is placed substantially in the middle of one of their faces. Gripping the product that appears on top of the stack through the dispensing window is often difficult. We also take the risk of taking at least two products at the same time instead of just one. Known cases generally have a longitudinal weld on one of their faces, like many food packaging. This weld is unsightly and gives the case a utilitarian character, unsuitable in particular for luxury goods, such as wipes impregnated with prestigious perfumes.
Les étuis de l'art antérieur sont réalisés à partir d'un matériau souple qui ne présente pas la solidité nécessaire à certaines utilisations, et risque par exemple de se déchirer, notamment si l'utilisateur tire sur 1 ' étiquette plus que cela est prévu par le concepteur de l'étui. L'étiquette risque alors de se décoller complètement et d'être difficile à recoller complètement et/ou de manière étanche.The cases of the prior art are made from a flexible material which does not have the solidity necessary for certain uses, and risks for example tearing, in particular if the user pulls the label more than expected. by the designer of the case. The label may then come off completely and be difficult to re-stick completely and / or tightly.
On connaît également dans l'art antérieur un étui refermable décrit dans le brevet WO91/04920. Cet étui vise à améliorer des étuis antérieurs présentant un trou prévu sur la face avant, pour permettre l'extraction d'un mouchoir, ou pour remplacer des étuis présentant une ligne de découpe s ' étendant jusqu'à une bande de scellage. Ce document propose de remplacer ce trou médian ou le volet délimité par la ligne de découpe et la bande de scellage par une ouverture délimitée par une ligne de découpe s ' étendant jusqu'au bord supérieur.Also known in the prior art is a resealable case described in patent WO91 / 04920. This case aims to improve previous cases having a hole provided on the front face, to allow the extraction of a handkerchief, or to replace cases having a cutting line extending to a sealing strip. This document proposes to replace this middle hole or the flap delimited by the cutting line and the sealing strip by an opening delimited by a cutting line extending to the upper edge.
Cette solution n'est pas satisfaisante, car la traction exercée sur le rabat peut entraîner une déchirure le long de la pliure formant le bord supérieur, notamment lorsque la traction comporte une composante parallèle à la pliure. Il en résulte alors une perte d ' étanchéité . Par ailleurs, le bord supérieur des lingettes est accessible lorsque l'étui est ouvert, ce qui peut conduire l'utilisateur à retirer la lingette non pas en la saisissant par le pli médian, mais en la saisissant par le bord supérieur. Cette mauvaise manipulation conduit à un défaut d'hygiène et à un risque d'extraction de plusieurs lingettes. Par ailleurs, le rabat peut se positionner de façon inclinée, ce qui amoindri l'étanchéité du conditionnement .This solution is not satisfactory, since the traction exerted on the flap may cause a tear along the fold forming the upper edge, in particular when the traction comprises a component parallel to the fold. This then results in a loss of tightness. Furthermore, the upper edge of the wipes is accessible when the case is open, which can lead to the user to remove the wipe not by grasping it by the middle fold, but by grasping it by the upper edge. This improper handling leads to a hygienic defect and a risk of extracting several wipes. Furthermore, the flap can be positioned in an inclined manner, which reduces the sealing of the packaging.
Le but de la présente invention est de proposer un étui pour produits qui remédie à certains au moins des inconvénients de l'art antérieur.The object of the present invention is to provide a case for products which overcomes at least some of the drawbacks of the prior art.
Suivant un premier aspect de l'invention, l'étui comprenant des moyens d'étanchéité et un dispositif d'ouverture disposé sur une face de l'étui et formé d'une étiquette adhésive et d'un clapet d'ouverture entouré au moins en partie par une ligne d'affaiblissement. L'étiquette adhésive recouvre entièrement le clapet d'ouverture et déborde au-delà de la ligne d'affaiblissement qui s'étend au voisinage d'un bord d'arrêt de ladite face. La ligne d'affaiblissement s'étend jusqu'au voisinage du bord supérieur, sans toutefois l'atteindre. La notion de voisinage dépend de la taille et de la dimension de l'étui. On peut considérer que la notion de voisinage s'entend, au sens du présent brevet, comme une distance inférieure à quelques pourcents, notamment moins de 10%, de la dimension parallèle à l'axe de traction.According to a first aspect of the invention, the case comprising sealing means and an opening device disposed on one face of the case and formed by an adhesive label and an opening flap surrounded at least partly by a line of weakness. The adhesive label completely covers the opening valve and projects beyond the line of weakness which extends in the vicinity of a stop edge of said face. The weakening line extends to, but does not reach, the vicinity of the upper edge. The notion of neighborhood depends on the size and dimension of the case. It can be considered that the concept of neighborhood is understood, within the meaning of this patent, as a distance less than a few percent, in particular less than 10%, of the dimension parallel to the axis of traction.
La notion de "sans venir en contact" s'entend comme préservant une faible distance, par exemple moins de quelques millièmes, notamment moins de 1%, de la dimension parallèle à l'axe de traction.The concept of "without coming into contact" is understood as preserving a short distance, for example less than a few thousandths, in particular less than 1%, of the dimension parallel to the axis of traction.
Cette solution permet d'éviter la déchirure de l'étui en cas de traction excessive sur le clapet de fermeture. Par ailleurs, il réserve une zone supérieure dans laquelle l'article conditionné reste maintenu, contrairement aux solutions comportant une bande de scellage .This solution makes it possible to avoid tearing the case in the event of excessive traction on the closing valve. In addition, it reserves an upper zone in which the conditioned article remains maintained, unlike the solutions comprising a sealing strip.
Le résultat obtenu est une meilleure étanchéité et une ouverture refermable qui évite que les articles soient saisis par la tranche. Ils ne peuvent être saisis que par le coin médian.The result obtained is a better seal and a resealable opening which prevents the articles from being grabbed by the edge. They can only be entered by the middle corner.
La ligne d'affaiblissement définit le contour d'une fenêtre de distribution qui est située de manière à chevaucher de préférence un bord du premier produit à distribuer .The weakening line defines the outline of a dispensing window which is situated so as to preferably overlap an edge of the first product to be dispensed.
Ainsi, l'utilisateur peut à l'aide d'un doigt sélectionner le premier produit qui se présente avant de le prélever facilement, en tirant sur le coin central. On évite ainsi les difficultés et les gaspillages àThus, the user can use a finger to select the first product which appears before taking it easily, by pulling on the central corner. This avoids the difficulties and wasteful
1 ' utilisation.1 use.
La zone s ' étendant entre les extrémités de la ligne d'affaiblissement et la tranche de l'étui a pour fonction d'arrêter le mouvement résultant de la traction sur l'étiquette. Il peut s'agir d'une zone appartenant au contour extérieur de l'étui, ou d'une zone formée en retrait du contour extérieur. La ligne d'affaiblissement présente de préférence deux extrémités allant sensiblement jusqu'au bord d'arrêt et entre lesquelles la matière de l'étui forme ligne d'articulation pour le clapet. Dans les différents modes de réalisation détaillés ci-après, la face portant la ligne d'affaiblissement sera appelée face avant. La face qui lui est opposée sera appelée face arrière.The area extending between the ends of the weakening line and the edge of the case has the function of stopping the movement resulting from the pulling on the label. It may be an area belonging to the outer contour of the case, or an area formed back from the outer contour. The weakening line preferably has two ends extending substantially to the stop edge and between which the material of the case forms a line of articulation for the valve. In the various embodiments detailed below, the face carrying the weakening line will be called the front face. The side opposite it will be called the back side.
Suivant un premier mode de réalisation de l'invention, l'étui est réalisé en matière plastique par exemple thermoformée ou injectée, et présente une coque formant la face arrière de l'étui et solidarisée à un élément de fermeture par soudure de leurs bords libres respectifs. Ledit élément de fermeture peut être constitué d'une membrane souple, mais prend avantageusement la forme d'une seconde coque formant la face avant de l'étui. Dans ce dernier cas, avant d'être soudées, les deux coques peuvent : être indépendantes et donc soudées ultérieurement par leur quatre bords libres, ouAccording to a first embodiment of the invention, the case is made of plastic material, for example thermoformed or injected, and has a shell forming the rear face of the case and secured to a closure element by welding their free edges respective. Said closure element may consist of a flexible membrane, but advantageously takes the form of a second shell forming the front face of the case. In the latter case, before being welded, the two shells can: be independent and therefore subsequently welded by their four free edges, or
- être thermoformées sur la même feuille de plastique de manière à être solidarisées par une partie de cette feuille faisant charnière. Les deux coques sont alors soudées par leurs trois bords libres restant. Dans ce premier mode de réalisation, le bord d ' arrêt peut être un bord commun à deux faces de 1 ' une des coques . Selon ce mode de réalisation, l'étui de 1 ' invention peut de manière avantageuse comporter une languette placée dans un plan parallèle à celui formé par les deux coques. Cette languette est utile pour la manipulation de l'étui. Elle peut également servir de support à un corps éventuellement creux.- be thermoformed on the same plastic sheet so as to be joined by a part of this sheet forming a hinge. The two shells are then welded by their three remaining free edges. In this first embodiment, the stop edge can be an edge common to two faces of one of the shells. According to this embodiment, the case of one invention can advantageously include a tongue placed in a plane parallel to that formed by the two shells. This tab is useful for handling the case. It can also serve as a support for a possibly hollow body.
Selon ce même mode de réalisation 1 ' étui peut encore comporter des moyens de poussée, destinés à faciliter la sortie des produits contenus dans ledit étui. Ces différents éléments seront décrits en détails plus avant dans la description.According to this same embodiment, the case may also include pushing means, intended to facilitate the exit of the products contained in said case. These various elements will be described in detail later in the description.
Suivant un second mode de réalisation de l'invention, l'étui est réalisé à partir d'une feuille de matériau souple et imperméable, par exemple de matière plastique, pliée en deux le long d'une ligne de pliage de manière à former deux parties sensiblement parallèles. Ces deux parties sont soudées entre elles par leurs bords libres respectifs.According to a second embodiment of the invention, the case is made from a sheet of flexible and impermeable material, for example plastic, folded in half along a fold line so as to form two substantially parallel parts. These two parts are welded together by their respective free edges.
Dans une première variante du second mode de réalisation de l'invention, la ligne d'affaiblissement est située au voisinage de la ligne de pliage. De manière préférentielle, le bord d'arrêt est constitué par la ligne de pliage. Selon cette variante, l'étiquette adhésive peut être disposée de manière à chevaucher la ligne de pliage. Cette disposition a l'avantage de fournir une étiquette dotée d'une très forte résistance à la traction .In a first variant of the second embodiment of the invention, the line of weakness is located in the vicinity of the fold line. Preferably, the stop edge is formed by the fold line. According to this variant, the adhesive label can be arranged so as to overlap the fold line. This arrangement has the advantage of providing a label with very high tensile strength.
Dans une autre variante du second mode de réalisation de l'invention, la ligne de pliage est localisée sur le bord opposé à la ligne d'affaiblissement.In another variant of the second embodiment of the invention, the fold line is located on the edge opposite the weakening line.
L'étiquette adhésive peut alors être placée de manière à ce qu'un bord de l'étiquette soit adjacent au bord de l'étui opposé à la ligne de pliage ; cette disposition a l'avantage d'être économique car elle nécessite peu de matière adhésive.The adhesive label can then be placed so that one edge of the label is adjacent to the edge of the case opposite the fold line; this arrangement has the advantage of being economical because it requires little adhesive material.
L'étiquette peut aussi être formée par un retour de la partie arrière de l'étui sur la partie avant.The label can also be formed by a return from the rear part of the case to the front part.
Ce retour chevauche la ligne d'affaiblissement de manière à recouvrir le clapet. Ce retour est éventuellement solidarisé par soudure au bord qui avoisine la ligne d'affaiblissement. De plus, il est rendu adhésif après onction par un polymère adhésif ou toute autre matière dotée de propriétés adhésives adéquates. Dans un dernier mode de réalisation de la présente invention, l'étui est réalisé à partir de deux pièces de matière plastique placées dans des plans parallèles, ces deux parties étant soudées entre elles par leurs quatre bords libres respectifs . Dans ce mode de réalisation, l'étiquette adhésive est disposée de manière à chevaucher le bord de l'étui qui lui est adjacent.This return overlaps the weakening line so as to cover the valve. This return is possibly joined by welding to the edge which borders the weakening line. In addition, it is made adhesive after anointing with an adhesive polymer or any other material with adequate adhesive properties. In a last embodiment of the present invention, the case is produced from two pieces of plastic material placed in parallel planes, these two parts being welded together by their four respective free edges. In this embodiment, the adhesive label is arranged so as to overlap the edge of the case which is adjacent to it.
Selon l'un quelconque de ces modes de réalisation, l'étiquette adhésive peut éventuellement être solidarisé à l'étui par soudure, par exemple avec le bord latéral qui lui est adjacent. Toutefois tout autre moyen de solidarisation adéquat peut être envisagé. Ainsi selon l'un ou l'autre des modes de réalisation, l'étui présente deux parties opposées, soudées entre elles par des bords latéraux, et dont les grandes faces ne sont traversées par aucune ligne de soudure. Celles-ci restent disponibles, par exemple pour recevoir un motif décoratif ou un message de type publicitaire.According to any one of these embodiments, the adhesive label can optionally be secured to the case by welding, for example with the lateral edge which is adjacent to it. However, any other suitable means of joining can be envisaged. Thus, according to one or other of the embodiments, the case has two opposite parts, welded together by lateral edges, and the large faces of which are not crossed by any weld line. These remain available, for example to receive a decorative motif or an advertising message.
Traditionnellement, les produits d'hygiène disposés en pile à l'intérieur de l'étui, sont plies chacun en un certain nombre de rectangles et/ou carrés élémentaires dont l'un constitue une face du produit plié tournée vers la fenêtre de distribution.Traditionally, the hygiene products arranged in a stack inside the case are each folded into a number of elementary rectangles and / or squares, one of which constitutes one side of the folded product facing the dispensing window.
Suivant un aspect de l'invention, l'article, comprenant des produits, comme notamment des produits en papier se présentant sensiblement sous la forme d'une feuille tels que par exemple des lingettes ou des mouchoirs, disposés en pile à l'intérieur de l'étui distributeur présentant une fenêtre de distribution sur l'une de ses faces, est caractérisé en ce que chaque produit présente sur une face tournée vers la fenêtre de distribution un coin de préhension situé en zone médiane de sa face avant, et en ce que le coin de préhension du premier produit à distribuer est positionné en face de la fenêtre de distribution de l'étui.According to one aspect of the invention, the article comprising products, such as in particular paper products which are substantially in the form of a sheet such as for example wipes or handkerchiefs, placed in a stack inside the dispensing case having a dispensing window on one of its faces, is characterized in that each product has, on one side facing the dispensing window, a gripping corner situated in the median zone of its front face, and in that that the gripping corner of the first product to be dispensed is positioned opposite the dispensing window of the case.
De manière avantageuse, les coins de préhension disposés sur les produits peuvent présenter un liseré dont la couleur se distingue de celle des produits d'hygiène. L'utilisateur peut ainsi distinguer du premier coup d'œil l'endroit précis par lequel il doit saisir le produit .Advantageously, the gripping corners disposed on the products can have a border whose color is distinguished from that of hygiene products. The user can thus distinguish at a glance the precise place by which he must enter the product.

Dans le mode de réalisation représenté aux figures 1 à 4, l'étui 1 est réalisé en matière plastique thermoformée semi-rigide et comprend deux coques complémentaires 3 de même forme et de mêmes dimensions, formées chacune d'un corps sensiblement en forme de tronc de pyramide à base rectangulaire ouverte entourée par un bord latéral 7.In the embodiment shown in Figures 1 to 4, the case 1 is made of semi-rigid thermoformed plastic and comprises two complementary shells 3 of the same shape and the same dimensions, each formed of a body substantially in the form of a trunk pyramid with open rectangular base surrounded by a side edge 7.
Les deux coques 3 sont disposées l'une contre l'autre, les deux cavités 5 communiquent l'une avec l'autre et les bords latéraux 7 respectifs sont soudés hermétiquement l'un à l'autre sur tout le pourtour des deux corps .The two shells 3 are arranged one against the other, the two cavities 5 communicate with each other and the respective lateral edges 7 are welded hermetically to each other all around the two bodies.
Les bords latéraux 7 sont de préférence de faible largeur devant les dimensions des cavités 5, en pratique leur largeur est la plus petite possible qui soit compatible avec une soudure efficace.The lateral edges 7 are preferably of small width compared to the dimensions of the cavities 5, in practice their width is the smallest possible which is compatible with effective welding.
Chaque corps présente un fond 15 sensiblement plan et une paroi latérale 17 qui relie le fond 15 et le bord latéral 7. Le fond 15 est séparé de la paroi latérale 17 adjacente par quatre arêtes s ' étendant selon le contour 19 du fond 15, obtenues lors du thermoformage.Each body has a substantially flat bottom 15 and a side wall 17 which connects the bottom 15 and the side edge 7. The bottom 15 is separated from the adjacent side wall 17 by four edges extending along the contour 19 of the bottom 15, obtained during thermoforming.
Le fond 15 de l'une des coques 3, dite "avant", comporte un dispositif d'ouverture 21. Le dispositif comprend une ligne d'affaiblissement 23 pratiquée dans le fond 15 de la coque 3, par exemple une ligne prédécoupée, qui n'est pas rectiligne ni fermée, et dont les deux extrémités 25 rejoignent le contour 19 en une même arête 119 formant bord d'arrêt comme il sera expliqué plus loin. Le dispositif d'ouverture 21 comprend également une étiquette adhésive 27 disposée sur l'extérieur de la coque 3. L'étiquette 27 recouvre entièrement un clapet 29 défini par la ligne d'affaiblissement 23 et la partie du bord d'arrêt 119 située entre les extrémités 25 de la ligne d'affaiblissement 23 formant ligne d'articulation du clapet. En outre, l'étiquette déborde du clapet 29, d'une part sur le fond 15 en ménageant une zone de débordement 31 tout autour de la ligne d'affaiblissement 23, et d'autre part au-delà du bord d'arrêt 119 en ménageant une zone de fixation 33 sur la paroi latérale 17.The bottom 15 of one of the shells 3, called "front", comprises an opening device 21. The device comprises a weakening line 23 formed in the bottom 15 of the hull 3, for example a pre-cut line, which is not straight or closed, and the two ends 25 of which join the contour 19 at the same edge 119 forming a stop edge as will be explained below. The opening device 21 also includes an adhesive label 27 placed on the outside of the shell 3. The label 27 entirely covers a valve 29 defined by the weakening line 23 and the part of the stop edge 119 located between the ends 25 of the weakening line 23 forming a line of articulation of the valve. In addition, the label overflows from the valve 29, on the one hand on the bottom 15 by providing an overflow zone 31 all around the weakening line 23, and on the other leaves beyond the stop edge 119 while providing a fixing zone 33 on the side wall 17.
A l'opposé de la zone de fixation 33, l' étiquette adhésive 27 est munie d'un onglet 35, prolongeant localement la zone de débordement 31. L'onglet 35 ne possède pas de revêtement adhésif.Opposite the fixing zone 33, the adhesive label 27 is provided with a tab 35, locally extending the overflow zone 31. The tab 35 has no adhesive coating.
Lors de la première utilisation de l'étui l'utilisateur prend l'onglet 35 entre deux doigts et le soulève en direction de la zone de fixation 33. La zone de débordement 31 de l'étiquette adhésive 27 se décolle du fond 15, pendant que le clapet 29 se découpe de proche en proche le long de la ligne d'affaiblissement 23. Le clapet 29 reste . - collé à l'étiquette adhésive 27 et laisse apparaître une fenêtre de distribution 37 à travers le fond 15.When using the case for the first time, the user takes the tab 35 between two fingers and lifts it up towards the fixing zone 33. The overflow zone 31 of the adhesive label 27 peels off from the bottom 15, during that the valve 29 is cut away step by step along the line of weakness 23. The valve 29 remains. - glued to the adhesive label 27 and reveals a dispensing window 37 through the bottom 15.
Le processus de découpe du fond 15 s'arrête automatiquement lorsqu'il atteint l'arête 119 aux extrémités 25 de la ligne d'affaiblissement 23, car: il n'y a pas sur la paroi latérale 17 de ligne d'affaiblissement pour guider la découpe, l'arête 119, séparant le plan du fond 15 et le plan de la face adjacente de la paroi latérale 17, forme alors un bord d'arrêt pour le décollage de l'étiquette adhésive 27 et pour la découpe du fond 15, car la traction exercée par l'utilisateur sur l'onglet 35 n'est pas, par rapport à la paroi latérale 17, orientée dans la direction d'un arrachement, le même bord d'arrêt 119 constitue, comme déjà exposé une ligne d'articulation naturelle (figure 1) entre le clapet 29 séparé du fond 15 et la paroi latérale 17. Si les extrémités 25 de la ligne d'affaiblissement 23 ne s'étendaient pas sensiblement jusqu'au contour 19, il y aurait un risque de prolongement de la découpe au-delà desdites extrémités 25, de façon irrégulière, sous forme de déchirure, jusqu'à ce que ladite déchirure rencontre ledit contour 19. La déchirure, une fois amorcée, pourrait même se prolonger au-delà. C'est pourquoi il est préféré que la ligne d'affaiblissement 23 soit voisine d'un bord d'arrêt tel que 119.The process of cutting the bottom 15 stops automatically when it reaches the edge 119 at the ends 25 of the weakening line 23, because: there is no weakening line on the side wall 17 to guide the cut, the edge 119, separating the plane of the bottom 15 and the plane of the adjacent face of the side wall 17, then forms a stop edge for peeling off the adhesive label 27 and for cutting the bottom 15 , because the traction exerted by the user on the tab 35 is not, relative to the side wall 17, oriented in the direction of a tearing, the same stop edge 119 constitutes, as already exposed a natural articulation line (FIG. 1) between the valve 29 separated from the bottom 15 and the side wall 17. If the ends 25 of the weakening line 23 do not not extend appreciably to the contour 19, there would be a risk of prolongation of the cut beyond said ends 25, irregularly, in the form of a tear, until said tear meets said contour 19. The tear, once started, could even extend beyond. This is why it is preferred that the weakening line 23 be near a stop edge such as 119.
Pour refermer l'étui 1, l'utilisateur procède de façon inverse à l'ouverture: il ramène le clapet 29 sur la fenêtre de distribution 37 et réapplique la zone de débordement 31 de l'étiquette adhésive 27 sur le fond 15. L'étiquette adhésive 27 est munie d'un revêtement adhésif qui la rend capable de se décoller et de se recoller plusieurs fois, en rétablissant à chaque fois 1 ' étanchéité .To close the case 1, the user proceeds in reverse to the opening: he brings the valve 29 back on the dispensing window 37 and reapplies the overflow zone 31 of the adhesive label 27 on the bottom 15. The adhesive label 27 is provided with an adhesive coating which makes it capable of peeling and sticking several times, reestablishing each time the seal.
L'étui 1 doit être étanche à l'air et à l'eau, pour éviter toute evaporation du liquide qui imprègne les produits d'hygiène 41 lorsqu'il s'agit de lingettes humides. A cet effet, l'étui 1 comprend des moyens d ' étanchéité, parmi lesquels l'étiquette adhésive 27, les lignes des soudure 8, et la ligne d'articulation formée par une partie de l'arête 119. Dans l'exemple représenté, les bords latéraux 7 peuvent présenter localement une largeur plus importante, par exemple pour réaliser une languette 9 pour la manipulation de 1 ' étui 1 et son accrochage sur présentoir de vente .The case 1 must be air and water tight, to avoid any evaporation of the liquid which impregnates the hygiene products 41 when it is a question of wet wipes. To this end, the case 1 comprises sealing means, among which the adhesive label 27, the lines of the welds 8, and the articulation line formed by a part of the edge 119. In the example shown, the side edges 7 may locally have a greater width, for example to produce a tongue 9 for handling the case 1 and hanging it on a sales display.
Dans une forme particulière de réalisation l'étui selon le premier mode de réalisation de l'invention comporte sur sa languette 9 des moyens aptes à solidariser l'étui sur un support. Un exemple de moyen de solidarisation consiste en un corps 10, éventuellement creux, dont la face arrière porte une matière adhésive. Ce corps 10 éventuellement creux a une profondeur au moins égale à la profondeur de la coque arrière de 1 ' étui 1. Dans le cas où le corps 10 est creux, il est susceptible de contenir un composé parfumé ou tout autre produit équivalent .In a particular embodiment, the case according to the first embodiment of the invention comprises on its tongue 9 means capable of securing the case on a support. An example of an attachment means consists of a body 10, possibly hollow, the rear face of which carries an adhesive material. This possibly hollow body 10 has a depth at least equal to the depth of the rear shell of the case 1. In the case where the body 10 is hollow, it may contain a perfumed compound or any other equivalent product.
Les moyens de solidarisation à un support peuvent être articulés à 1 ' étui par tout moyen approprié telle qu'une charnière 11. Cette articulation autorise une liberté de mouvement relatif entre l'étui 1 et les moyens 10 de solidarisation à un support. Ainsi, lorsque l'étui 1 est solidarisé à un support, par exemple le tableau de bord d'une automobile, par la face arrière du moyen 10 de solidarisation, il bénéficie, grâce à la charnière 11, d'une certaine liberté de mouvement. Cette caractéristique permet notamment une prise en main facilitée de l'étui de 1 ' invention . Comme le montrent les figures 1 et 4, l'article d'hygiène comprend également une pile 39 de produits d'hygiène 41 plies et empilés selon un parallélépipède dans 1 ' espace intérieur de 1 ' étui 1. La fenêtre de distribution 37 du dispositif d'ouverture 21 chevauche un bord 43 de la pile 39 et en particulier du premier produit à distribuer 45.The means for securing to a support can be articulated to the case by any suitable means such as a hinge 11. This articulation allows freedom of relative movement between the case 1 and the means 10 for securing to a support. Thus, when the case 1 is secured to a support, for example the dashboard of an automobile, by the rear face of the securing means 10, it benefits, thanks to the hinge 11, from a certain freedom of movement . This characteristic allows in particular an easier handling of the case of one invention. As shown in FIGS. 1 and 4, the hygiene article also comprises a stack 39 of hygiene products 41 folded and stacked according to a parallelepiped in the interior space of the case 1. The dispensing window 37 of the device 21 overlaps an edge 43 of the stack 39 and in particular of the first product to be dispensed 45.
Afin d'éviter les problèmes liés au déplacement du coin de préhension 47 lors des utilisations successives de l'étui 1, celui-ci comprend des moyens de poussée 45. Ceux-ci vont pousser la pile 39 de produits d'hygiène 41 vers le dispositif d'ouverture 21, et favoriser ainsi le prélèvement du premier produit 41 à distribuer tout en empêchant le déplacement du coin de préhension 47 par rapport à la fenêtre de distribution 37.In order to avoid the problems associated with the movement of the gripping corner 47 during successive uses of the case 1, the latter comprises pushing means 45. These will push the stack 39 of hygiene products 41 towards the opening device 21, and thus favor the removal of the first product 41 to be dispensed while preventing the displacement of the gripping corner 47 relative to the dispensing window 37.
Lesdits moyens de poussée 45 peuvent comprendre un ressort, par exemple un ressort à lames 45, disposé entre la pile 39 de produits 41 et le fond 15 de la coque 3 qui ne présente pas de dispositif d'ouverture, et représenté en vue de profil sous la forme d'un V à la figure 4.Said thrust means 45 may comprise a spring, for example a leaf spring 45, disposed between the stack 39 of products 41 and the bottom 15 of the shell 3 which does not have an opening device, and shown in profile view in the form of a V in Figure 4.
Toutefois, les moyens de poussée 45 peuvent encore être formés par la face arrière de l'étui. Il suffit pour cela que cette dernière présente une concavité 4, maximale au repos, c'est à dire lorsque l'étui est vide. La concavité 4 est éventuellement reliée à la face arrière de l'étui par des soufflets 6 comme montré à la figure 4C . Lors de la mise en place de la pile de lingettes dans l'étui, les lingettes viennent appuyer contre la concavité 4. Au fur et à mesure de la sortie des lingettes, la concavité 4 fait pression, agissant ainsi comme un moyen de poussée sur les lingettes. Les produits d'hygiène 41 sont plies de manière à présenter un coin de préhension 47 sur leur face avant 49 le long du bord 43 qui est chevauché par la fenêtre de distribution et à distance des angles 44 de la pile .However, the pushing means 45 can also be formed by the rear face of the case. It suffices for this that the latter has a concavity 4, maximum at rest, that is to say when the case is empty. The concavity 4 is possibly connected to the rear face of the case by bellows 6 as shown in FIG. 4C. When placing the stack of wipes in the case, the wipes press against the concavity 4. As the wipes come out, the concavity 4 presses, thus acting as a means of pushing on the wipes. The hygiene products 41 are folded so as to present a gripping corner 47 on their front face 49 along the edge 43 which is overlapped by the dispensing window and at a distance from the corners 44 of the stack.
La fenêtre de distribution 37 découvre le coin de préhension 47 du premier produit d'hygiène 41 à distribuer lorsque le clapet 29 est soulevé.The dispensing window 37 discovers the gripping corner 47 of the first hygiene product 41 to be dispensed when the valve 29 is raised.
On va maintenant définir un premier mode de pliage d'un produit d'hygiène 41 qui réalise un coin de préhension 47 sur une face dudit produit, comme illustré aux figures 5 et 6.We will now define a first mode of folding a hygiene product 41 which produces a gripping corner 47 on one face of said product, as illustrated in FIGS. 5 and 6.
La figure 5 représente un produit 41 en configuration dépliée sous la forme d'un rectangle R de longueur A et de largeur B. On a matérialisé en pointillés des lignes de partage 51 parallèles aux bords de longueur A et des lignes de partage 53 parallèles aux bords de largeur B.FIG. 5 represents a product 41 in an unfolded configuration in the form of a rectangle R of length A and width B. Divided lines 51 parallel to the edges of length A and dividing lines 53 parallel to the lines have been materialized edges of width B.
Ces lignes de partage 51, 53 partagent le rectangle R en rectangles élémentaires 55, 57.These dividing lines 51, 53 divide the rectangle R into elementary rectangles 55, 57.
Dans l'exemple représenté, il y a une seule ligne de partage 53 qui définit deux rangées de rectangles élémentaires 55, 57 présentant tous une même longueur élémentaire C qui définit la plus grande dimension du produit 41 plié parallèlement à la longueur A du produit déplié. Par contre il y a deux lignes de partage 51 qui définissent deux colonnes adjacentes de rectangles élémentaires 55, présentant tous une largeur élémentaire D, et une colonne de rectangles élémentaires 57 présentant une largeur élémentaire E inférieure à la largeur élémentaire D.In the example shown, there is a single dividing line 53 which defines two rows of elementary rectangles 55, 57 all having the same elementary length C which defines the largest dimension of the product 41 folded parallel to the length A of the product unfolded. On the other hand, there are two dividing lines 51 which define two adjacent columns of elementary rectangles 55, all having an elementary width D, and a column of elementary rectangles 57 having an elementary width E less than the elementary width D.
La largeur élémentaire D définit la plus petite dimension du produit 41 plié, parallèle au bord d'arrêt 119 dans 1 ' étui . De préférence la largeur D est sensiblement double de la largeur E. La colonne des rectangles élémentaires 57 qui présente la plus petite largeur E est adjacente à un bord du rectangle R.The elementary width D defines the smallest dimension of the folded product 41, parallel to the stop edge 119 in the case. Preferably the width D is substantially double the width E. The column of elementary rectangles 57 which has the smallest width E is adjacent to an edge of the rectangle R.
Le pliage du produit 41 est illustré à la figure 6. Il comprend les étapes suivantes: on plie en accordéon le rectangle R suivant les deux lignes de partage 51, en formant trois volets dont deux présentent la largeur D et le troisième la largeur E, on plie ensuite l'accordéon le long de la ligne de partage 53 comme indiqué par la flèche 59.The folding of the product 41 is illustrated in FIG. 6. It comprises the following steps: the rectangle R is folded in accordion along the two dividing lines 51, forming three flaps, two of which have the width D and the third the width E, the accordion is then folded along the dividing line 53 as indicated by the arrow 59.
On met ainsi en contact deux rectangles élémentaires 55 de largeur D, et on oriente vers l'extérieur les rectangles élémentaires 57 de largeur E.Two elementary rectangles 55 of width D are thus brought into contact, and the elementary rectangles 57 of width E are oriented towards the outside.
On obtient de cette manière un coin de préhension 47 situé en zone médiane de l'un des bords du produit 41, ledit coin de préhension 47 pouvant être facilement séparé du rectangle élémentaire sous-jacent 55 par un mouvement illustré par la flèche 61 aux figures 6 et 1.In this way, a gripping corner 47 is obtained located in the middle zone of one of the edges of the product 41, said gripping corner 47 being able to be easily separated from the underlying elementary rectangle 55 by a movement illustrated by arrow 61 in FIGS. 6 and 1.
Lorsque l'on forme une pile 39 de produits d'hygiène 41 plies comme on vient de le décrire, on veille à ce que chaque produit présente un coin de préhension 47 le long d'un même bord de la pile, en les orientant tous de la même façon ou par exemple alternativement dans un sens et dans l'autre.When forming a stack 39 of hygienic products 41 folded as just described, it is ensured that each product has a gripping corner 47 along the same edge of the stack, orienting them all in the same way or for example alternately in one direction and in the other.
Lorsque l'on place la pile dans l'étui, on fait en sorte que ce bord de la pile s'étende le long du bord d'arrêt 119 de l'étui.When the battery is placed in the case, this edge of the stack is made to extend along the stop edge 119 of the case.
Ce mode de pliage est particulièrement adapté aux étuis définissant un espace intérieur sensiblement parallélépipédique, et dont la fenêtre d'ouverture 37 est disposée le long d'un petit côté de l'étui, comme c'est le cas pour l'étui représenté aux figures 1 à 4.This folding mode is particularly suitable for cases defining a substantially parallelepiped interior space, and whose opening window 37 is arranged along a short side of the case, as is the case for the case shown in FIGS. Figures 1 to 4.
Les figures 7 et 8 illustrent un second mode de réalisation de l'étui 1, également apte à recevoir des produits d'hygiène plies suivant le premier mode de pliage, et qui ne sera décrit que par ses différences avec le premier mode de réalisation.Figures 7 and 8 illustrate a second embodiment of the case 1, also suitable for receiving folded hygiene products according to the first folding mode, and which will only be described by its differences from the first embodiment.
L'étui 2 est cette fois réalisé à partir d'une pièce 65 découpée dans une feuille de matière plastique souple . La pièce 65 présente un axe longitudinal de symétrie 67, et une ligne de pliage 69 perpendiculaire à l'axe de symétrie 67 et partageant la pièce 65 en deux parties 71, 72 ayant des contours extérieurs sensiblement symétriques par rapport à la ligne de pliage. Elles présentent le long de ce contour un bord latéral 73 dont le contour intérieur est illustré à la figure 8 par une ligne pointillée 75. L'étui 2 est réalisé en pliant la pièce 65 le long de la ligne de pliage 69 et en soudant l'un contre l'autre les des bords latéraux 73 respectifs des deux parties 71, 72. L'étui est fermé hermétiquement sur son pourtour par le pliage la soudure. La ligne d'affaiblissement 23 est située sur l'une des parties 71.The case 2 is this time made from a piece 65 cut from a sheet of flexible plastic. The part 65 has a longitudinal axis of symmetry 67, and a fold line 69 perpendicular to the axis of symmetry 67 and dividing the part 65 into two parts 71, 72 having substantially external contours symmetrical with respect to the fold line. They have along this contour a lateral edge 73, the interior contour of which is illustrated in FIG. 8 by a dotted line 75. The case 2 is produced by folding the part 65 along the fold line 69 and by welding the 'one against the other the respective side edges 73 of the two parts 71, 72. The case is hermetically sealed around its periphery by folding the weld. The weakening line 23 is located on one of the parts 71.
Dans une première variante de ce mode de réalisation, les extrémités 25 de la ligne 23 s'étendent jusqu'à la ligne de pliage 69. L'étiquette adhésive 27 recouvre le clapet 39 et déborde tout autour de celui-ci sur la partie 71 correspondante de l'étui 2, et soit au-delà de la ligne de pliage 69 sur l'autre partie 72 de l'étui 2 soit placée de manière à ce que le bord de l'étiquette 27 soit adjacent à la ligne de pliage 69.In a first variant of this embodiment, the ends 25 of the line 23 extend to the fold line 69. The adhesive label 27 covers the valve 39 and extends all around it on the part 71 corresponding to the case 2, and either beyond the fold line 69 on the other part 72 of the case 2 is placed so that the edge of the label 27 is adjacent to the fold line 69.
Dans une seconde variante de ce mode de réalisation, la ligne de pliage 69 est localisée sur le bord de la partie 71 opposé à la ligne d'affaiblissement 23. L'étiquette 27 est alors formée par un retour de la partie arrière 72 de l'étui sur la partie avant 71. Ce retour chevauche la ligne d'affaiblissement 23 de manière à recouvrir le clapet d'ouverture 37. Ce retour est rendu adhésif après onction par un polymère adhésif. Il est particulièrement avantageux d'utiliser à cette fin un adhésif dont la polymérisation est contrôlable au moyen de la température. L'homme du métier est à même de déterminer à quel stade de la fabrication de l'étui il sera opportun de conférer au polymère ses propriétés adhésives.In a second variant of this embodiment, the fold line 69 is located on the edge of the part 71 opposite the weakening line 23. The label 27 is then formed by a return from the rear part 72 of the case on the front part 71. This return overlaps the line of weakness 23 so as to cover the opening valve 37. This return is made adhesive after anointing with an adhesive polymer. It is It is particularly advantageous to use for this purpose an adhesive whose polymerization is controllable by means of the temperature. Those skilled in the art are able to determine at what stage of the manufacture of the case it will be advisable to give the polymer its adhesive properties.
Lors de la première utilisation de l'étui 2, la partie 71 se découpe le long de la ligne d'affaiblissement 23, dégageant une fenêtre de distribution 37 (figure 7) . Le processus de découpe s'arrête de lui-même sur la ligne de pliage 69, qui constitue un bord d'arrêt.When the case 2 is used for the first time, the part 71 is cut along the weakening line 23, freeing a distribution window 37 (FIG. 7). The cutting process stops itself on the folding line 69, which constitutes a stop edge.
Les moyens d' étanchéité de l'étui 2 comprennent la nature du matériau constitutif de l'étui, l'étiquette adhésive 27, la ligne de soudure 74 et la ligne de pliage 69. Un autre mode de réalisation de l'étui 2, également apte à recevoir des produits d'hygiène plies suivant le premier mode de pliage, et qui ne sera décrit que par ses différences avec le mode de réalisation de l'étui 2 explicité ci-dessus. L'étui 2 est cette fois réalisé à partir de deux pièces 65 découpées dans une feuille de matière plastique souple. Les pièces 65 sont placées dans des plans parallèles et forment deux parties (71, 72) sensiblement parallèles, Les deux parties (71, 72) sont soudées entre elles par leurs quatre bords libres (73) respectifs.The sealing means of the case 2 comprise the nature of the material constituting the case, the adhesive label 27, the weld line 74 and the fold line 69. Another embodiment of the case 2, also suitable for receiving folded hygiene products according to the first folding mode, and which will only be described by its differences with the embodiment of the case 2 explained above. The case 2 is this time made from two pieces 65 cut from a sheet of flexible plastic. The parts 65 are placed in parallel planes and form two parts (71, 72) substantially parallel. The two parts (71, 72) are welded together by their four free edges (73) respectively.
Dans cette forme de réalisation, l'étiquette adhésive (27) est disposée de manière à chevaucher le bord de l'étui qui lui est adjacent. La figure 7 illustre l'arrangement de la pile 39 de produits d'hygiène 41 à l'intérieur de l'étui 2. Il est à noter qu'avec l'étui suivant ce mode de réalisation, contrairement aux étuis souples de l'art antérieur, peut disposer les produits d'hygiène dans l'étui par remplissage de celui-ci et non par enveloppement de pile de produits avec une feuille de plastique.In this embodiment, the adhesive label (27) is arranged so as to overlap the edge of the case which is adjacent to it. FIG. 7 illustrates the arrangement of the stack 39 of hygiene products 41 inside the case 2. It should be noted that with the case according to this embodiment, unlike the flexible cases of the prior art, can arrange hygiene products in the case by filling it and not by wrapping a stack of products with a plastic sheet.
En particulier on peut préparer 1 ' étui en pliant le long de la ligne de pliage, puis en soudant une partie des bords latéraux, avant de remplir la poche ainsi formée avec la pile de produits, et de souder la dernière partie des bords latéraux.In particular, the case can be prepared by folding along the fold line, then by welding part of the side edges, before filling the pocket thus formed with the stack of products, and welding the last part of the side edges.
Une variante d'exécution du second mode de réalisation de l'étui 2 est illustrée à la figure 9. Cette fois, la fenêtre de distribution 37 est disposée le long d'un grand côté de l'étui 2. A cette variante d'exécution correspond un second mode de pliage des produits d'hygiène 41 qui va être décrit en référence aux figures 10 et 11. La figure 10 représente un produit 41 en configuration dépliée sous la forme d'un rectangle R de longueur A et de largeur B. On a matérialisé en pointillé des lignes de partage 77 parallèles aux bords de longueur A et des lignes de partage 79 parallèles aux bords de largeur B.An alternative embodiment of the second embodiment of the case 2 is illustrated in Figure 9. This time, the dispensing window 37 is arranged along a long side of the case 2. In this variant of execution corresponds to a second mode of folding the hygiene products 41 which will be described with reference to FIGS. 10 and 11. FIG. 10 represents a product 41 in the unfolded configuration in the form of a rectangle R of length A and width B Divided lines 77 parallel to the edges of length A and dividing lines 79 parallel to the edges of width B have been shown in dotted lines.
Ces lignes de partage 77, 79 partagent le rectangle R en rectangles élémentaires 81. Dans l'exemple représenté, il y a deux lignes de partage 77 qui définissent trois rangées 83, 85, 87 et deux lignes de partage 79 qui définissent trois colonnes 89, 91, 93 de rectangles élémentaires 81. La rangée centrale 83 présente une longueur élémentaire F qui définit la plus grande dimension du produit 41 plié. Les rangées 85, 87 présentent respectivement des longueurs élémentaires G, H, toutes deux plus petites que la longueur élémentaire F. De préférence, les longueurs élémentaires G et H sont complémentaires de sorte que leur somme G + H est sensiblement égale à la longueur élémentaire F.These dividing lines 77, 79 divide the rectangle R into elementary rectangles 81. In the example shown, there are two dividing lines 77 which define three rows 83, 85, 87 and two dividing lines 79 which define three columns 89, 91, 93 of elementary rectangles 81. The central row 83 has a length elementary F which defines the largest dimension of the folded product 41. The rows 85, 87 respectively have elementary lengths G, H, both smaller than the elementary length F. Preferably, the elementary lengths G and H are complementary so that their sum G + H is substantially equal to the elementary length F.
Les colonnes adjacentes 89 et 91 présentent toutes deux une largeur élémentaire J qui définit la plus petite dimension du produit 41 plié. La colonne 93 présente une largeur élémentaire K réduite par rapport à J. Cette colonne 93 est adjacente à un bord du rectangle R.The adjacent columns 89 and 91 both have an elementary width J which defines the smallest dimension of the folded product 41. Column 93 has an elementary width K reduced with respect to J. This column 93 is adjacent to an edge of rectangle R.
Le pliage du produit 41 est illustré à la figure 11. Il comprend les étapes suivantes: - on plie en accordéon le rectangle R suivant les lignes de partage 79, en formant trois volets de largeur respective G, F, H; l'accordéon présente sur deux faces opposées des volets de largeur réduite qui partent de deux bords latéraux opposés; - on plie ensuite l'accordéon le long des lignes de partage 79, par exemple encore en accordéon, comme illustré par la flèche 95 à la figure 11. On prend comme face avant du produit celle où les rectangles" élémentaires sont les plus grands.The folding of the product 41 is illustrated in FIG. 11. It comprises the following steps: - the rectangle R is folded in accordion along the dividing lines 79, forming three flaps of respective width G, F, H; the accordion has on two opposite sides shutters of reduced width which start from two opposite lateral edges; the accordion is then folded along the dividing lines 79, for example still in an accordion, as illustrated by the arrow 95 in FIG. 11. The front face of the product is taken as the one where the "elementary rectangles are the largest.
On obtient ainsi un coin de préhension 47 situé en zone médiane d'un bord de la face avant du produit 41, ledit coin de préhension pouvant être facilement séparé du rectangle élémentaire 81 sous-jacent par un mouvement illustré par la flèche 97 à la figure 11.A gripping corner 47 is thus obtained located in the middle zone of an edge of the front face of the product 41, said gripping corner being able to be easily separated from the underlying elementary rectangle 81 by a movement illustrated by the arrow 97 in the figure. 11.
Un mode de réalisation avantageux est décrit en référence aux figures 12 à 15. L'étui peut être réalisé par pliage et scellage latéral d'un film complexe formé, comme représenté en figure 12, par : une couche (100) d'un matériau adhésif, notamment un adhésif thermoactivable sur sa face extérieure et reactivable à froid sur la surface en contact avec le film de matière plastique (101) ; une couche (101) formée par une matière plastique telle que du PET ;An advantageous embodiment is described with reference to FIGS. 12 to 15. The case can be produced by folding and lateral sealing of a complex film formed, as shown in FIG. 12, by: a layer (100) of a material adhesive, in particular an adhesive which can be heat activated on its external face and which can be reactivated cold on the surface in contact with the plastic film (101); a layer (101) formed by a plastic material such as PET;
- une couche barrière (102) formée par une feuille d'aluminium ;- a barrier layer (102) formed by an aluminum sheet;
- une couche extérieure (103) formée par une matière plastique telle que du polyéthylène .- an outer layer (103) formed by a plastic material such as polyethylene.
Ce complexe est découpé pour former deux lobesThis complex is cut to form two lobes
(105, 106) se rejoignant en une ligne médiane (107) . Les lobes (105, 106) présentent une forme générale rectangulaire, et avantageusement les bords latéraux (108,(105, 106) joining in a center line (107). The lobes (105, 106) have a generally rectangular shape, and advantageously the lateral edges (108,
109, 110, 111) sont convexes. Le film complexe est ensuite préparé à l'aide d'une matrice de rainage, comme représenté en figure 13. Un premier couteau (112) découpe à mi-chair le film complexe pour découper totalement la couche d'adhésif (100), le long d'une ligne (114) correspondant au bord de la fenêtre d'accès aux lingettes. Cette découpe peut être réalisé avec un outil de tranchage présentant des matrices munies de lames de découpes en acier.109, 110, 111) are convex. The complex film is then prepared using a creasing matrix, as shown in FIG. 13. A first knife (112) cuts half-through the complex film to completely cut the layer of adhesive (100), the along a line (114) corresponding to the edge of the wipe access window. This cutting can be carried out with a slicing tool having dies provided with steel cutting blades.
Sur l'autre face, côté polyéthylène , un deuxième couteau (113) réalise une découpe partielle des trois autres (101 à 103), selon la ligne d'affaiblissement (23) .On the other side, on the polyethylene side, a second knife (113) cuts the three others (101 to 103) partially, along the weakening line (23).

Bien sûr, l'invention n'est pas limitée aux exemples qui viennent d'être décrits et de nombreux aménagements peuvent être apportés à ces exemples sans sortir du cadre de l'invention.Of course, the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention.
On pourrait envisager des étuis de formes différentes, pour chacun des deux modes de réalisation.One could consider cases of different shapes, for each of the two embodiments.
Les exemples qui ont été décrits concernent un étui pour produits d'hygiène, mais on peut envisager les mêmes étuis destinés à d'autres produits, sans sortir du cadre de l'invention.The examples which have been described relate to a case for hygiene products, but it is possible to envisage the same cases intended for other products, without departing from the scope of the invention.
On pourrait envisager que les produits d'hygiène 41 ne soient pas de forme rectangulaire, mais par exemple de forme carrée. Les modes de pliage précédemment décrits pourraient être appliqués de la même manière.It could be envisaged that the hygiene products 41 are not of rectangular shape, but for example of square shape. The folding methods described above could be applied in the same way.
Les associations qui ont été décrites entre chaque mode de réalisation ou variante d'exécution de l'étui de chaque mode de pliage sont préférées mais non limitatives.The associations which have been described between each embodiment or variant of execution of the case of each folding mode are preferred but not limiting.
Chacun des modes de réalisation des articles de la présente invention peut comprendre un mode particulier d'incorporation des produits. L'article objet de la présente invention peut être garni de lingettes ou de tout autre produit selon les procédés connus de l'homme du métier et ce à différents stades de l'élaboration de 1 ' étui . Ainsi, de manière illustrative mais non limitative, lorsque l'étui qui compose l'article est formé d'une feuille souple, il est possible de former un premier bord par pliage de la feuille, puis de former deux autres bords par soudure puis de remplir l'étui ainsi formé par le côté resté ouvert qui ne sera soudé qu'après remplissage de 1 'étui.Each of the embodiments of the articles of the present invention may include a particular mode of incorporation of the products. The article subject to present invention can be lined with wipes or any other product according to methods known to those skilled in the art and this at different stages of the development of one case. Thus, by way of illustration but not limitation, when the case which composes the article is formed of a flexible sheet, it is possible to form a first edge by folding the sheet, then to form two other edges by welding then to fill the case thus formed with the side which remains open, which will only be welded after filling the case.
Selon la qualité des lingettes employées, 1 ' imprégnation peut se faire de manière individuelle pour chaque lingette et donc avant la mise en place dans les étuis, ou de manière groupée à n'importe quelle étape du processus d'incorporation. Depending on the quality of the wipes used, the impregnation can be done individually for each wipe and therefore before being placed in the cases, or in a grouped fashion at any stage of the incorporation process.
