Description

La présente invention concerne un étui à bec verseur inviolable et dépliable, pouvant contenir des produits fluides, tels que de la poudre et des grains. Elle concerne plus particulièrement un étui du type défini par une boite, dont les côtés sont de préférence parallèles, et dans lequel le bec précité est réalisé sur les bords de la boite et est délimité par les parois latérales, supérieures et frontales de celle-ci. Cet étui est aussi d'un type pour lequel le bec verseur est réalisé comme une partie d'un matériau de faible épaisseur, du type feuille ou similaire, à partir duquel la boite est fabriquée, et de plus, il se déploie d'une position de fermeture à une position d'ouverture de la boite et vice-versa. Ce matériau de faible épaisseur sera appelé ci-après "matériau en feuille".The present invention relates to a tamper-evident spout case and unfoldable, which may contain fluids, such as powder and grains. It relates more particularly to a case of the type defined by a box, the sides of which are preferably parallel, and in which the abovementioned spout is made on the edges of the box and is delimited by the side walls, upper and front thereof. This case is also of a type for which the spout is made as part of a thin material, sheet type or similar, from which the box is made, and moreover, it deploys from a closed position to an open position of the box and vice versa. This thin material will be called hereinafter "material in leaf".

Dans l'état de la technique, plusieurs types d'étuis pour produits en poudre ou grains sont connus, que ce soit des produits pour le nettoyage, par exemple du savon en poudre ou en granulés, ou des produits alimentaires, par exemple du lait en poudre, du café, des épices, des céréales, etc., pour citer seulement les cas les plus communs ou fréquents dans leur usage. La plupart de ces étuis ont la forme d'une boite parallélépipédique rectangle scellée, pour laquelle, dans l'un des coins on a imprimé des lignes qui indiquent la découpe à réaliser, par exemple à l'aide d'une paire de ciseaux ou de tout autre instrument tranchant, pour ouvrir un orifice de sortie du produit contenu et, en outre, pour y introduire les parois latérales et la paroi frontale de la boite dans le but de conformer un canal ou bec verseur du produit. Dans d'autres cas, les lignes imprimées dans le coin de la boite coïncident avec un affaiblissement de la paroi du matériau en feuille pour réaliser une découpe en pressant manuellement sur la zone définie par les susdites lignes.In the state of the art, several types of cases for products in powder or grains are known, whether for cleaning products, for example example of soap powder or granules, or food products, for example example milk powder, coffee, spices, cereals, etc., to quote only the most common or frequent cases in their use. Most of these cases have the shape of a sealed rectangular box which, in one of the corners we have printed lines which indicate the cut to make, for example using a pair of scissors or any other cutting instrument, to open an outlet for the contained product and, in in addition, to introduce the side walls and the front wall of the box into the purpose of conforming a product channel or spout. In other cases, lines printed in the corner of the box coincide with a weakening of the wall of the sheet material for cutting by pressing manually on the area defined by the above lines.

Le principal désavantage de ce type d'étui réside essentiellement dans le fait que, une fois le matériau découpé, et qu'un orifice d'ouverture et un canal ou bec verseur sont formés, la boite ne peut plus être fermée convenablement, ce qui non seulement peut occasionner le renversement du produit si la boite bascule accidentellement, mais en plus expose les produits à l'entrée de particules, d'objets étrangers et/ou de liquides, ce qui dégrade les propriétés physiques et/ou chimiques de ces produits et, en général, leur pureté même. Cet inconvénient doit être évité tout particulièrement quand il s'agit de produits alimentaires.The main disadvantage of this type of case is essentially in that once the material has been cut, and an opening and channel or spout are formed, the box can no longer be closed suitably, which not only can cause the product if the box accidentally tilts, but additionally exposes the products to the entry of particles, foreign objects and / or liquids, which degrades the physical and / or chemical properties of these products and, in general, their purity itself. This drawback should be avoided especially when it these are food products.

Un autre type d'étui de même nature inclut, dans le coin destiné à un orifice de sortie et au bec verseur, un accessoire rajouté à la paroi frontale de la boite, en général en métal, qui consiste en une sorte de bouchon-bec verseur dépliable articulé à travers sa partie inférieure, et qui est la plupart du temps scellé, par exemple à l'aide d'une étiquette autocollante, pour garantir l'inviolabilité de l'étui. On pourrait estimer que ce type d'étui avec bouchon-bec incorporé résout, en principe, les problèmes des boites qui s'ouvrent par coupure, comme celles citées préalablement.Another type of case of the same kind includes, in the corner intended for a outlet and spout, an accessory added to the front wall of the box, usually made of metal, which consists of a kind of spout unfoldable articulated through its lower part, and which is most of the time sealed, for example with a self-adhesive label, to guarantee the inviolability of the case. We could estimate that this type of case with cap-spout incorporated solves, in principle, the problems of boxes that open by cut, like those previously mentioned.

Cependant, cette configuration n'est pas exempte d'inconvénients. Les matériaux et les pièces utilisés, les machines et les étapes des processus de fabrication pour la mise en forme de la boite à partir du matériau en feuille et le montage du bouchon-bec dans cette boite, ont une incidence considérable sur les coûts de fabrication, ce qui se ressent sur le prix de la vente final au public.However, this configuration is not without drawbacks. The materials and parts used, machinery and process steps manufacturing for the shaping of the box from the sheet material and the mounting the cap in this box, have a considerable impact on manufacturing costs, which affects the price of the final sale to the public.

L'invention vise à pallier les inconvénients des étuis de l'art connu, et dont certains viennent d'être rappelés, à titre d'exemples les plus représentatifsThe invention aims to overcome the drawbacks of cases of the known art, and some of which have just been recalled, as the most representative examples

L'invention se fixe pour but un étui qui non seulement simplifie considérablement les aspects structurels de la boite à bec verseur devant être obtenue, mais aussi réduit considérablement les coûts de fabrication et, de plus, offre des avantages qui se manifestent en particulier lors de l'utilisation de l'étui par un consommateur.The invention sets itself the goal of a case which not only simplifies considerably the structural aspects of the spout box to be obtained, but also considerably reduces manufacturing costs and, plus, offers benefits that manifest themselves especially when using the case by a consumer.

En effet, l'étui selon l'invention, tel qu'il sera décrit de façon plus détaillée ci-après, autorise une fabrication très simple, rapide et bon marché. En ce qui concerne son usage, il sera montré qu'il réunit tout à la fois les avantages pratiques des étuis conformés en une seule pièce de matériau en feuille et dispose d'un bouchon-bec verseur efficace et de manipulation très facile.Indeed, the case according to the invention, as will be described in more detail detailed below, allows very simple, fast and inexpensive manufacturing. With regard to its use, it will be shown that it combines all the practical advantages of cases made from a single piece of material foil and has an efficient spout and handling easy.

La présente invention se fixe donc pour but de fournir un étui à bec verseur inviolable et dépliable, pouvant contenir des produits fluides, tels que de la poudre et des grains, étui réalisé à partir d'une seule pièce de matériau en feuille, dans lequel le bec verseur constitué une partie du matériau en feuille.The present invention therefore sets itself the aim of providing a case with a beak tamper-evident and unfoldable pourer, which may contain fluid products, such as powder and grains, case made from a single piece of material in sheet form, in which the spout consists of part of the material leaf.

La présente invention se fixe aussi pour but de fournir un étui à bec verseur inviolable et dépliable, dans lequel le bec peut s'ouvrir sans qu'il soit nécessaire d'utiliser des éléments tranchants ou similaires et, une fois l'étui ouvert et formée un orifice de sortie du produit contenu dans l'étui, le bec fait aussi office d'organe de fermeture.The present invention is also intended to provide a beaker case tamper-proof and unfoldable pourer, in which the spout can be opened without being necessary to use sharp or similar elements and, once the case open and formed an outlet for the product contained in the case, the spout also as a closing organ.

La présente invention se fixe enfin pour but de fournir un étui à bec verseur inviolable et dépliable, dans lequel les éléments qui lui concèdent le caractère d'inviolabilité font partie du matériau en feuille constituant l'étui.The present invention finally sets itself the aim of providing a beak case tamper-evident and unfoldable pourer, in which the elements which concede it inviolability are part of the sheet material constituting the case.

L'invention a donc pour objet principal un étui à bec verseur inviolable et dépliable, pouvant contenir des produits fluides, tels que de la poudre et des grains, du type où ledit étui est défini par une boite, aux côtés préférentiellement parallèles, dans laquelle ledit bec est réalisé sur les bords de ladite boite et est délimité par les parois latérales, supérieure et frontale de celle-ci, de telle sorte que ledit bec verseur fasse partie d'une pré-découpe ou gabarit de matériau en feuille, à partir duquel est fabriquée ladite boite, et ayant la faculté de passer d'une position de fermeture à une position d'ouverture de ladite boite et vice-versa, et dont ledit bec définit une fermeture de l'orifice de sortie et un organe de canalisation du produit contenu dans ladite boite, caractérisé en ce que ledit bord est un bord tronqué qui présente une portion plane inclinée vers le bas en partant d'une empreinte transversale formée sur la paroi supérieure de ladite boite et de premiers plis des parois latérales de ladite boite, alors qu'en outre, ledit bec verseur est défini sur la paroi frontale de ladite boite par une portion plane dépliable qui se projette à partir d'une empreinte transversale d'articulation inférieure et comprend un secteur central, et de second plis des parois latérales de ladite boite, cette portion plane dépliable aboutissant sur un bord supérieur fixé de façon détachable à ladite boite.The main object of the invention is therefore a tamper-proof spout case and unfoldable, which can contain fluid products, such as powder and grains, of the type where said case is defined by a box, on the sides preferably parallel, in which said spout is formed on the edges of said box and is delimited by the side, upper and front walls of this, so that said spout is part of a pre-cut or sheet material template, from which said box is made, and having the ability to move from a closed position to an open position of said box and vice versa, and of which said spout defines a closure of the orifice of outlet and a member for channeling the product contained in said box, characterized in that said edge is a truncated edge which has a portion plane inclined downwards starting from a transverse imprint formed on the upper wall of said box and first folds of the side walls of said box, while in addition, said spout is defined on the front wall of said box by a foldable flat portion which projects from a transverse footprint of lower joint and includes a central sector, and second folds of the side walls of said box, this flat portion unfoldable leading to an upper edge detachably attached to said box.

On va maintenant décrire un exemple de réalisation d'un étui selon un mode de réalisation préféré de l'invention par référence aux figures 1 à 6. Sur ces figures, les éléments identiques portent les mêmes références et ne seront re-décrits qu'en tant que de besoin.We will now describe an embodiment of a case according to a preferred embodiment of the invention with reference to Figures 1 to 6. On these figures, identical elements have the same references and will not be re-described as necessary.

On considère en premier lieu les figures 1 et 2. Sur ces figures, on peut observer que l'étui selon de la présente invention est défini par une boite sensiblement parallélépipédique rectangle, désignée par le numéro de référence général 1, qui présente des parois latérales 2, une paroi frontale 3, une paroi supérieure 4, une paroi inférieure 5 et une paroi postérieure 6. Un bec verseur 8 est réalisé dans un bord tronqué 7 de la boite 1. Le bec verseur 8 est délimité par les parois latérales 2, frontale 3 et supérieure 4 de la boite 1. Le bec verseur 8 fait partie d'une pré-découpe de matériau en feuille, par exemple du carton, tel que le montrent les figures 5 et 6, à partir duquel on fabrique la boite 1. Le bec verseur 8 peut se déplacer d'une position de fermeture vers une position d'ouverture de la boite 1 et vice-versa, définissant à la fois une fermeture de l'orifice de sortie du produit contenu et une portion de canalisation du produit contenu dans la boite.We first consider Figures 1 and 2. In these figures, we can observe that the case according to the present invention is defined by a box substantially rectangular rectangle, designated by the number of general reference 1, which has side walls 2, a front wall 3, an upper wall 4, a lower wall 5 and a rear wall 6. A pouring spout 8 is produced in a truncated edge 7 of the box 1. The pouring spout 8 is delimited by the side walls 2, front 3 and upper 4 of the box 1. The pouring spout 8 is part of a pre-cutting of sheet material, by example of cardboard, as shown in Figures 5 and 6, from which manufactures the box 1. The pouring spout 8 can move from a position of closing towards an open position of the box 1 and vice-versa, defining at both a closure of the outlet for the contained product and a portion of channeling of the product contained in the box.

Le bord tronqué 7 présente une portion plane 9 inclinée vers le bas définie à partir d'une empreinte transversale 10 formée sur la paroi supérieure 4 et des premiers plis 11 des parois latérales 2 de la boite 1. Dans le cadre de la présente description, les mots "empreinte" et "plis" seront utilisés indistinctement et leur signification devra être interprétée, de façon plus générale, comme se rapportant à tout type de marquage, ligne de pré-découpe ou ligne d'affaiblissement le long desquels on peut faire un plis ou pliage d'une partie souhaitée. Le bec verseur 8 est défini sur la paroi frontale 3 de la boite 1 par une portion plané dépliable, qui se projette à partir d'une empreinte transversale 12 d'articulation inférieure et comprend un secteur central 13 et de seconds plis 14 des parois latérales 2. La portion plane dépliable aboutit sur un bord supérieur 15 qui est fixé de façon détachable sur la portion plane 9 de la paroi supérieure 4 par une languette de sécurité 16 qui se projette du bord supérieur 15 sur la portion incliné 9 à laquelle elle est fixée, par exemple, avec de la colle ou un autre type de matériau adhésif. Éventuellement la languette de sécurité 16 peut aussi s'étendre partiellement sur la paroi supérieure 4, ou elle peut être disposée sous la ligne de plis 10, et même en dessous de l'extrémité la plus exposée de la languette 16, en fonction de ce qui est considéré le plus pratique. De plus, le bord supérieur 15 peut être fixé de façon détachable à la portion inclinée 9 sans l'aide de la languette de sécurité 16. En d'autres termes, le bord 15 peut être directement collé à la portion 9, par exemple par un secteur central 13, et il se détache de ce dernier en tirant sur une languette supérieure 17.The truncated edge 7 has a flat portion 9 inclined downwards defined from a transverse cavity 10 formed on the upper wall 4 and first folds 11 of the side walls 2 of the box 1. In the context of this description, the words "imprint" and "folds" will be used indistinctly and their meaning should be interpreted more general, as relating to any type of marking, pre-cutting line or line of weakness along which one can fold or fold a desired part. The pouring spout 8 is defined on the front wall 3 of the box 1 by a foldable planed portion, which projects from an imprint transverse 12 of lower articulation and includes a central sector 13 and second folds 14 of the side walls 2. The unfoldable flat portion leads to a upper edge 15 which is detachably fixed on the flat portion 9 of the upper wall 4 by a safety tab 16 which projects from the edge upper 15 on the inclined portion 9 to which it is fixed, for example, with glue or other type of adhesive material. Possibly the tongue security 16 may also extend partially on the upper wall 4, or it can be placed under the fold line 10, and even below the most exposed end of the tongue 16, depending on what is considered the most practical. In addition, the upper edge 15 can be fixed so detachable from the inclined portion 9 without using the safety tab 16. In in other words, the edge 15 can be directly glued to the portion 9, by example by a central sector 13, and it is detached from the latter by pulling on an upper tab 17.

Pour permettre que la portion dépliable qui constitue le bec verseur 8 se détache, la languette 16 présente une pré-découpe, comprenant deux parties, référencées 15a et 15b respectivement, coïncidant avec des segments latéraux du bord supérieur 15 défini sur chaque côté d'une découpe centrale 16', qui, à son tour définit la languette 17 d'accrochage, de traction, de détachement et de dépliage du bec verseur 8.To allow the unfoldable portion which constitutes the spout 8 comes off, the tongue 16 has a pre-cut, comprising two parts, referenced 15a and 15b respectively, coinciding with segments sides of the upper edge 15 defined on each side of a central cutout 16 ', which in turn defines the tongue 17 for hooking, pulling, detachment and unfolding of the spout 8.

Sur les figures 2 et 4, on peut apprécier clairement comment la languette 16 reste fixée sur la portion plane inclinée 9 après avoir détaché et déplié le bec verseur 8 en tirant de la languette 17.In Figures 2 and 4, we can clearly see how the tongue 16 remains fixed on the inclined flat portion 9 after having detached and unfolded the spout 8 by pulling on the tongue 17.

Sur les figures 1 et 3, on voit comment, en position pliée, le bec verseur 8 ferme la boite 1, alors que, sur les figures 2 et 4, on peut observer que lorsque le bec verseur 8 est déplié, un orifice de sortie 18 étant formé, à travers lequel le produit contenu dans la boite 1 peut s'écouler librement, le produit étant canalisé par le bec verseur 8.In Figures 1 and 3, we see how, in the folded position, the spout pourer 8 closes the box 1, whereas in FIGS. 2 and 4, we can observe that when the spout 8 is unfolded, an outlet orifice 18 being formed, at through which the product contained in box 1 can flow freely, the product being channeled through the spout 8.

Pour décrire plus en détail la réalisation de l'étui objet de la présente invention comme étui et bec verseur formés d'une seule pièce à partir d'une pré-découpe de matériau en feuille, comme du carton, on va maintenant considérer les figures 5 et 6.To describe in more detail the realization of the case object of the present invention as a case and spout formed in one piece from a pre-cutting of sheet material, such as cardboard, we will now consider Figures 5 and 6.

En effet, sur la figure 5 on voit que dans la pré-découpe illustrée on a défini deux plans ou rabats supérieurs 4a et 4b, pour former la paroi supérieure 4 et les plans ou les rabats inférieurs 5a et 5b, pour former la paroi inférieure 5 de la boite 1, auxquelles s'ajoutent, respectivement, les rabats 4c et 5d qui se projettent de la paroi postérieure 6 pour unir cette dernière avec les parois supérieures 4, 5 et 5c. D'autre part, de la paroi 2 que l'on voit à gauche de cette figure 5, un rabat 6a est projeté pour unir la paroi latérale 2 à la paroi postérieure 6. Pour former la portion plane inclinée 9, à partir des rabats 4a et 4b se projettent, respectivement, les rabats 9a et 9b, lesquels restent totalement ou partiellement superposés lors du pliage de cette pré-découpe pour la fabrication de la boite 1. Ces rabats 9a et 9b comportent des lignes de pliage10a et 10b, respectivement.Indeed, in Figure 5 we see that in the illustrated pre-cut we have defined two upper planes or flaps 4a and 4b, to form the upper wall 4 and the lower planes or flaps 5a and 5b, to form the lower wall 5 of box 1, to which are added, respectively, the flaps 4c and 5d which are project from the rear wall 6 to unite the latter with the walls higher 4, 5 and 5c. On the other hand, from the wall 2 that we see to the left of this figure 5, a flap 6a is projected to join the side wall 2 to the wall posterior 6. To form the inclined flat portion 9, from the flaps 4a and 4b project, respectively, the flaps 9a and 9b, which remain totally or partially superimposed when folding this pre-cut for the manufacture of the box 1. These flaps 9a and 9b have lines of folding10a and 10b, respectively.

Un secteur central 13 est défini par des portions inférieures 13a et supérieures 13b, qui pour plus de clarté ont étés séparées par une ligne pointillée. La portion inférieure 13a présente des bords latéraux droits 19. La portion supérieure 13b, présente substantiellement la forme d'un obus, et comporte des bords latéraux curvilignes 20, lesquels se rejoignent à l'extrémité du secteur central 13 où se définit la languette d'accroche 17.A central sector 13 is defined by lower portions 13a and upper 13b, which for clarity have been separated by a line dashed. The lower portion 13a has straight side edges 19. The upper portion 13b, substantially in the form of a shell, and has curvilinear side edges 20, which meet at the end of the central sector 13 where the catch tab 17 is defined.

Entre les rabats 9a et 9b et les parois latérales respectives 2, on voit les premiers plis 11 des parois 2, lesquels sont des secteurs triangulaires dont le petit angle α, représenté sur la figure 6, est défini par un sommet 21 et coïncide avec l'empreinte transversale 10 de la paroi supérieure 4. Dans un mode de réalisation préféré, l'angle α est approximativement égal à 30° et, lors du pliage du matériau en feuille pour la fabrication de la boite 1, il détermine une inclinaison approximative de 60° de la portion plane inclinée 9 par rapport à la paroi supérieure 4. Cependant, il doit être clair que la valeur des angles peut varier, par exemple, en fonction des procédés de fabrication de la boite, ou en fonction des proportions volumétriques de la boite 1.Between the flaps 9a and 9b and the respective side walls 2, we see the first folds 11 of the walls 2, which are triangular sectors of which the small angle α, represented in FIG. 6, is defined by a vertex 21 and coincides with the transverse imprint 10 of the upper wall 4. In a preferred embodiment, the angle α is approximately equal to 30 ° and, when of the folding of the sheet material for the manufacture of the box 1, it determines an approximate inclination of 60 ° of the flat portion inclined 9 relative to at the top wall 4. However, it should be clear that the value of the angles may vary, for example, depending on the manufacturing processes of the box, or according to the volumetric proportions of box 1.

Chacun des seconds plis 14 des parois latérales 2 de la boite 1 est défini par un premier secteur triangulaire 22, dont le sommet 23 correspond au petit angle (β (voir figure 6) coïncidant avec l'extrémité correspondante de l'empreinte d'articulation transversale 12 du bec verseur 8. Le petit côté du premier secteur triangulaire 22 coïncide avec un segment opposé 24 du bord supérieur 15 de la portion plane dépliable qui forme le bec 8, alors qu'un côté 22' du premier secteur triangulaire 22, qui est adjacent au secteur central 13, coïncide avec le bord droit latéral 19 de ce dernier et se prolonge jusqu'au bord supérieur 15 du secteur plan dépliable.Each of the second pleats 14 of the side walls 2 of the box 1 is defined by a first triangular sector 22, the vertex 23 of which corresponds to small angle (β (see Figure 6) coinciding with the corresponding end of the transverse articulation imprint 12 of the pouring spout 8. The short side of the first triangular sector 22 coincides with an opposite segment 24 of the edge upper 15 of the unfoldable flat portion which forms the spout 8, while one side 22 ′ of the first triangular sector 22, which is adjacent to the central sector 13, coincides with the lateral right edge 19 of the latter and extends to the edge upper 15 of the foldable flat sector.

Entre chacun des premiers secteurs triangulaires 22 et la portion supérieure 13b du secteur central 13 du bec verseur 8, on définit une portion à propriété élastique 25. Celle-ci, lors de la traction à partir de la languette 17, réagit, de façon corrélative, aussi bien à l'ouverture comme à la fermeture du bec verseur 8. La portion à propriété élastique 25 est dotée d'une forme substantiellement triangulaire et présente un côté curviligne coïncidant avec le segment défini par le bord curviligne 20 de la portion supérieure 13b du secteur central 13. De plus, cette portion à propriété élastique 25 a un premier côté droit coïncidant avec un segment supérieur du côté adjacent du premier secteur triangulaire 22 et, d'autre part, un deuxième côté droit coïncidant avec un segment intermédiaire 26 du bord supérieur 15 du secteur central 13, à partir duquel se projette la languette de sécurité 16.Between each of the first triangular sectors 22 and the portion upper 13b of the central sector 13 of the pouring spout 8, a portion is defined elastic property 25. This, when pulled from the tongue 17, reacts, in a correlative way, as well to the opening as to the closing of the spout 8. The portion with elastic property 25 has a shape substantially triangular and has a curvilinear side coinciding with the segment defined by the curvilinear edge 20 of the upper portion 13b of the sector central 13. In addition, this portion with elastic property 25 has a first side right coinciding with an upper segment on the adjacent side of the first triangular sector 22 and, on the other hand, a second right side coinciding with an intermediate segment 26 of the upper edge 15 of the central sector 13, from which the safety tab 16 projects.

Selon une variante de réalisation préférée, dans les seconds plis précités 14, le petit angle du premier secteur triangulaire 22 est approximativement de 15° à 18°, ce qui, lors du pliage de la pré-découpe pour la fabrication de la boite 1, définit une inclinaison approximative de 30° du secteur central 13 avec la portion à propriété élastique 25, ce par rapport à la paroi frontale 3. De cette façon, au moins une partie de la portion supérieure 13b du secteur 13 et de la portion 25 se superposent sur la portion plane inclinée 9, fermant l'orifice de sortie 17 (voir figure 3). De nouveau, il doit être clair que les valeurs des angles peuvent varier, par exemple, en fonction des procédés de fabrication de la boite, ou en fonction des proportions volumétriques de la boite 1.According to a preferred embodiment, in the second folds mentioned above 14, the small angle of the first triangular sector 22 is approximately from 15 ° to 18 °, which, when folding the pre-cut for the manufacture of box 1, defines an approximate inclination of 30 ° of the central sector 13 with the portion with elastic property 25, this with respect to the front wall 3. In this way, at least part of the upper portion 13b of sector 13 and portion 25 are superimposed on the flat portion inclined 9, closing the outlet 17 (see Figure 3). Again, it must be It is clear that the values of the angles can vary, for example, depending on the manufacturing processes of the box, or according to the proportions volumetric of the box 1.

Il faut remarquer que le périmètre des premiers plis 11 et des deuxièmes plis 14 des parois latérales 2 de la boite 1 sont imposés par des empreintes qui, dans le cas particulier des seconds plis 14 définissent des lignes d'articulation du bec verseur 8. Les premiers plis 11 définissent les surfaces de repos du bec verseur 8, quand il est fermé, et d'adhésion de la languette 16.Note that the perimeter of the first folds 11 and the second folds 14 of the side walls 2 of the box 1 are imposed by imprints which, in the particular case of the second pleats 14 define articulation lines of the pouring spout 8. The first folds 11 define the rest surfaces of the spout 8, when closed, and adhesion of the tab 16.

Sur la figure 6, on a représenté les principales proportions des dimensions telles que les relations angulaires et longueur/largeur des parties de la pré-découpe de la figure 5, lesquelles sont liées entre elles pour permettre la construction du bec verseur 8 selon les particularités fonctionnelles déjà citées.In FIG. 6, the main proportions of the dimensions such as angular relationships and length / width of parts of the pre-cut in Figure 5, which are linked together to allow the construction of the spout 8 according to the functional features already cited.

En effet, en premier lieu on remarque que la largeur I 17 de la languette d'accrochage 17 et la largeur I 16 associée aux bords curvilignes 20 d'induction de l'ouverture et fermeture du bec verseur 8, ont une relation dans un rapport 2/3, de I 16 par rapport à I 17. D'autre part, la largeur I 3 de la paroi frontale 3, dans ce cas de réalisation, est approximativement égale à la hauteur h 22 prise entre l'empreinte 12 de la paroi frontale 3 et un côté 22' adjacent du secteur triangulaire 22, étant, en plus, la longueur du bord latéral droit 19 de la portion centrale 13 la moitié de la susdite hauteur h 22. Dans les parois latérales 2, la génératrice de plis définie par le bords 22' du secteur triangulaire 22 et la résultante du pliage, définissent une variation angulaire estimée de pliage compris entre 5 et 30°. Dans cet exemple de réalisation, dans le plis 11, avec un angle α =30°, on définit un angle β =15° du secteur triangulaire 22, et un angle δ = 135° entre les côtés 11' et 22". Bien que ces valeurs soient des valeurs adoptées dans un mode de réalisation préféré de la présente invention, elles ne sont précisées qu'à titre d'exemple non limitatif. Tout en restant dans le cadre de l'invention, on peut naturellement adopter d'autres valeurs, selon l'application précise considérée.In fact, first of all, we note that the width I 17 of the hooking tongue 17 and the width I 16 associated with the curvilinear edges 20 for inducing the opening and closing of the pouring spout 8, have a relationship in a relationship 2/3, from I 16 compared to I 17 . On the other hand, the width I 3 of the front wall 3, in this embodiment, is approximately equal to the height h 22 taken between the cavity 12 of the front wall 3 and an adjacent side 22 'of the triangular sector 22 , being, in addition, the length of the right lateral edge 19 of the central portion 13 half of the above height h 22 . In the side walls 2, the fold generator defined by the edges 22 ′ of the triangular sector 22 and the resultant of the folding, define an estimated angular variation in folding between 5 and 30 °. In this exemplary embodiment, in fold 11, with an angle α = 30 °, an angle β = 15 ° of the triangular sector 22 is defined, and an angle δ = 135 ° between the sides 11 'and 22 ". Although these values are values adopted in a preferred embodiment of the present invention, they are only specified by way of non-limiting example. While remaining within the scope of the invention, other values can naturally be adopted , depending on the specific application considered.

La ligne de pointillés T est la résultante du pliage du secteur 22, alors que la ligne de pointillés T' est la résultante du pliage du secteur 11 sur la paroi 2, quand ceux-ci se retrouvent en position rabattue. T s'obtient en fonction de l'angle β choisi, avec en outre β = γ.The dotted line T is the result of the folding of sector 22, then that the dotted line T 'is the result of the folding of sector 11 on the wall 2, when these are found in the folded position. T is obtained as a function of the angle β chosen, with in addition β = γ.

Comme il a été expliqué dans la présente description, lorsque la paroi supérieure 4 est rabattue et réalisée, celle-ci crée une surface de repos coplanaire à la résultante du pliage des parois latérales 2, mais avec une translation proportionnelle à l'épaisseur du matériau en feuille utilisé pour la construction de la boite 1. L'épaisseur du matériau est représentée par la distance de séparation entre les lignes T et T'. Comme il a été rappelé précédemment, toutes les valeurs, telles que celles des angles et des longueurs des lignes de plis peuvent varier en fonction de la taille et du type de boite, du matériau en feuille de la boite et des procédés de fabrication. Par exemple, pour les boites de tailles spéciales, on peut prévoir des lignes de plis, appelées aussi empreintes, 26 qui sont disposées sur les plans ou rabats 9a et 9b.As explained in the present description, when the wall upper 4 is folded down and made, this creates a rest surface coplanar with the result of the folding of the side walls 2, but with a translation proportional to the thickness of the sheet material used for the construction of the box 1. The thickness of the material is represented by the separation distance between lines T and T '. As he was reminded previously, all values, such as angles and lengths of fold lines may vary depending on the size and type of box, sheet material of the box and manufacturing methods. Through example, for special size boxes, we can provide fold lines, also called imprints, 26 which are arranged on the planes or flaps 9a and 9b.

Grâce à ces empreintes 26, une machine de fabrication peut plier plus facilement les rabats 9a et 9b vers l'intérieur, pour former la portion inclinée 9, lorsque la taille de la boite fait que la portion 9a ou 9b est plus résistante. Aidés par les lignes 26, chaque rabat 9a et 9b forme un arc vers le bas lorsqu'ils sont pressés par une partie de la machine prévue à cet effet et, de cette façon, la portion 9 tourne autour de la ligne 11'et tout au long de l'angle α.Thanks to these imprints 26, a manufacturing machine can bend more easily the flaps 9a and 9b inwards, to form the inclined portion 9, when the size of the box makes the portion 9a or 9b more resistant. helped by the lines 26, each flap 9a and 9b forms an arc downwards when they are pressed by a part of the machine provided for this purpose and, in this way, the portion 9 rotates around line 11 ′ and along the angle α.
