Description

L'invention concerne un emballage comprenant un élément en un matériau semi-rigide, tel que le carton ou carton ondulé, et au moins une feuille autoscellante de protection des articles conditionnés.The invention relates to a package comprising an element made of a semi-rigid material, such as cardboard or corrugated cardboard, and at least one self-sealing sheet for protecting the packaged articles.

On connaît des caisses d'emballage d'articles avec :

  • un élément en carton ondulé comprenant une partie de fond et, quatre parois dressées par rapport à la partie de fond, la partie de fond et les parois définissant un espace intérieur pour recevoir un contenu, et
  • une feuille autoscellante, comprenant une feuille en un matériau recyclable avec le carton, par exemple du papier, recouverte d'une composition autoscellante, et fixée aux quatre parois de l'élément en carton, de façon à laisser le fond de l'élément en carton accessible pour la dépose de l'article à conditionner.
Boxes for packaging articles with:
  • a corrugated cardboard member including a bottom portion and four walls raised from the bottom portion, the bottom portion and the walls defining an interior space for receiving a content, and
  • a self-sealing sheet, comprising a sheet of recyclable material with the cardboard, for example paper, covered with a self-sealing composition, and fixed to the four walls of the cardboard element, so as to leave the bottom of the element accessible carton for the removal of the article to be packaged.

Une fois l'article installé dans l'espace intérieur de l'emballage, l'utilisateur replie les parties de la feuille autoscellante sur cet article. Ce faisant, des portions de la feuille autoscellante viennent en contact avec d'autres portions de cette feuille, par leurs cotés recouverts de la composition autoscellante, ce qui assure un maintien en place de l'article conditionné.Once the article installed in the inner space of the package, the user folds the parts of the self-sealing sheet on this article. In doing so, portions of the self-sealing sheet come into contact with other portions of this sheet, by their sides covered with the self-sealing composition, which ensures a hold in place of the packaged article.

Il existe un besoin pour un conditionnement plus économique et plus simple à mettre en oeuvre.
Il est proposé un emballage comprenant :

  1. a) un élément en matériau semi rigide, tel que le carton ou le carton ondulé, comprenant une partie de fond et, au moins deux parois dressées par rapport à la partie de fond, la partie de fond et les au moins deux parois définissant un espace intérieur pour recevoir un contenu, et
  2. b) un premier et un deuxième éléments de feuille autoscellante, chaque élément de feuille autoscellante comprenant une feuille de papier recouverte de composition autoscellante sur une face seulement.
There is a need for packaging that is more economical and easier to implement.
It is proposed a package comprising:
  1. a) a semi-rigid material element, such as cardboard or corrugated cardboard, comprising a bottom portion and at least two walls raised from the bottom portion, the bottom portion and the at least two walls defining a bottom portion; interior space for receiving content, and
  2. b) first and second self-sealing sheet members, each self-sealing sheet member comprising a paper sheet coated with self-sealing composition on one side only.

Les éléments de feuille autoscellante sont fixés à l'élément en matériau semi-rigide de façon à pouvoir passer d'une position de superposition à deux parois respectives, pour la dépose du contenu dans l'espace intérieur de l'emballage, à une position repliée sur le contenu. L'emballage est agencé de sorte que lorsque les éléments de feuille autoscellante sont en position de superposition, le premier élément de feuille autoscellante ait sa face recouverte de composition autoscellante du coté de la paroi correspondant à cet élément de feuille et le deuxième élément de feuille autoscellante ait sa face recouverte de composition autoscellante du coté de l'espace intérieur, afin que lorsque le premier élément de feuille autoscellante puis le deuxième élément de feuille autoscellante sont ensuite positionnés, par exemple rabattus, en position repliée sur le contenu, définissant ainsi une zone de recouvrement desdits éléments de feuille autoscellante, les deux faces recouvertes de composition autoscellante desdits éléments de feuille autoscellante soient en regard l'une de l'autre sur les parties de ces feuilles correspondant à la zone de recouvrement.The self-sealing sheet elements are attached to the element semi-rigid material so as to be able to pass from a superposition position to two respective walls, for the removal of the contents in the interior of the packaging, to a folded position on the contents. The package is arranged so that when the self-sealing sheet elements are in the superposition position, the first self-sealing sheet member has its self-sealing composition coated face on the side of the wall corresponding to that sheet member and the second sheet member. self-sealant has its face covered with self-sealing composition on the side of the interior space, so that when the first self-sealing sheet element and then the second self-sealing sheet element are then positioned, for example folded, in the folded position on the contents, thus defining a covering area of said self-sealing sheet elements, the two sides covered with self-sealing composition of said self-sealing sheet elements are facing each other on the parts of these sheets corresponding to the overlap zone.

Ainsi, il suffit de rabattre les éléments de feuille autoscellante suivant un ordre donné pour obtenir un scellement sur toute la zone de recouvrement. Le procédé de conditionnement est ainsi bien plus aisé à mettre en oeuvre que dans l'art antérieur, et pourra en particulier être mécanisé.Thus, it is sufficient to fold the self-sealing sheet elements in a given order to obtain a seal on the entire area of recovery. The packaging method is thus much easier to implement than in the prior art, and may in particular be mechanized.

En outre, la quantité de matériau de feuille autoscellante peut être moindre que dans l'art antérieur, dans la mesure où toute la surface de la zone de recouvrement est scellée.In addition, the amount of self-sealing sheet material may be less than in the prior art, as the entire surface of the cover area is sealed.

Par « composition autoscellante », on entend une composition telle que lorsque cette composition recouvre une feuille de papier, elle crée une adhésion avec une autre couche de cette même composition recouvrant une feuille de papier, mais non avec du carton ou du papier laissé brut.By "self-sealing composition" is meant a composition such that when this composition covers a sheet of paper, it creates an adhesion with another layer of the same composition covering a sheet of paper, but not with cardboard or paper left raw.

La composition autoscellante pourra par exemple comprendre du caoutchouc naturel, ou bien encore d'un mélange tel que décrit dans le document WO 2000/049102 .The self-sealing composition may, for example, comprise natural rubber, or else a mixture as described in the document WO 2000/049102 .

Le papier des éléments de feuille autoscellante peut avantageusement être obtenu par recyclage de papier et/ou de carton.The paper of the self-sealing sheet elements can advantageously be obtained by recycling paper and / or cardboard.

Les parois auxquelles sont superposées les éléments de feuille autoscellante respectives peuvent avantageusement être à l'opposé l'une de l'autre. Alternativement, on pourrait tout à fait prévoir que les éléments de feuille autoscellante soient superposés à deux parois adjacentes respectives.The walls on which the respective self-sealing foil elements are superimposed may advantageously be opposite to each other. Alternatively, one could quite predict that the self-sealing sheet elements are superimposed on two respective adjacent walls.

Les éléments de feuille autoscellante peuvent être fixés à l'élément en matériau semi-rigide de façon indépendante l'un de l'autre.The self-sealing sheet elements can be attached to the semi-rigid material element independently of one another.

Avantageusement et de façon non limitative, les éléments de feuille autoscellante peuvent être issus d'une même feuille autoscellante. L'installation des éléments de feuille autoscellante en est ainsi facilitée.Advantageously and in a nonlimiting manner, the self-sealing sheet elements may be from the same self-sealing sheet. The installation of self-sealing sheet elements is thus facilitated.

Cette feuille autoscellante comprend une feuille de papier dont une face seulement est recouverte sur toute sa surface de composition autoscellante.This self-sealing sheet comprises a sheet of paper, one side only of which is covered over its entire surface with self-sealing composition.

Cette feuille autoscellante peut être restée d'une seule pièce.This self-sealing sheet can be left in one piece.

Par exemple, on pourra prévoir une seule feuille autoscellante fixée au fond de l'emballage et vrillée à 180° sur elle-même au niveau du fond de l'emballage, afin que l'un des éléments de feuille autoscellante soit superposé à la paroi correspondante avec sa face enduite de composition autoscellante en regard de la paroi, et l'autre des éléments de feuille autoscellante soit superposé à la paroi correspondante avec sa face enduite de composition autoscellante du côté de l'espace intérieur.For example, there may be provided a single self-sealing sheet attached to the bottom of the package and twisted 180 ° on itself at the bottom of the package, so that one of the self-sealing sheet elements is superimposed on the wall corresponding with its side coated with self-sealing composition facing the wall, and the other self-sealing sheet elements is superimposed on the corresponding wall with its self-sealing composition coated side of the inner space.

Avantageusement et de façon non limitative, les premier et deuxième éléments de feuille autoscellante peuvent être obtenus par découpe de la feuille autoscellante.Advantageously and without limitation, the first and second self-sealing sheet elements can be obtained by cutting the self-sealing sheet.

Il peut être prévu une ligne dite de prédécoupe constituée d'une succession de segments de coupes espacés facilitant une séparation manuelle des deux parties.It can be provided a so-called precut line consisting of a succession of spaced section segments facilitating a manual separation of the two parts.

Avantageusement et de façon non limitative, on pourra prévoir deux moyens de fixation, par exemple de fixation ponctuelle ou bien encore de fixation linéaire, par exemple deux lignes de colle.Advantageously and without limitation, two fixing means may be provided, for example point fixing or even linear fastening, for example two lines of glue.

Dans le cas d'une découpe, effectuée par exemple en tirant manuellement de part et d'autre d'une ligne de prédécoupe, ou bien encore en découpant la feuille au moyen d'un cutter, ces moyens de fixation peuvent être de part et d'autre de la ligne de découpe ainsi obtenue. Chaque élément de feuille autoscellante ainsi obtenu peut ainsi être fixé à l'élément en matériau semi rigide par le moyen de fixation correspondant.In the case of a cut, made for example by manually pulling on both sides of a precut line, or even by cutting the sheet by means of a cutter, these fixing means can be on both sides. else of the cutting line thus obtained. Each self-sealing sheet element thus obtained can thus be fixed to the element made of semi-rigid material by the corresponding fixing means.

Le montage de l'emballage peut en outre être automatisé.The assembly of the packaging can also be automated.

Chaque élément de feuille autoscellante peut être fixé à l'élément en matériau semi-rigide par un seul moyen de fixation, avantageusement situé prés d'une extrémité de l'élément de feuille autoscellante, de sorte qu'une partie de l'élément de feuille autoscellante peut être entrainée en mouvement.Each self-sealing sheet element can be attached to the semi-rigid material element by a single fastening means, advantageously located near one end of the self-sealing foil member so that a portion of the self-sealing foil member can be driven in motion.

Lors de la fixation de la feuille autoscellante, l'élément en matériau rigide ou semi-rigide peut avantageusement être à l'état de flan, ce qui facilite l'installation de la feuille autoscellante.When fixing the self-sealing sheet, the rigid or semi-rigid material element may advantageously be in the blank state, which facilitates the installation of the self-sealing sheet.

Les moyens de fixation linéaire peuvent avantageusement être parallèles ou sensiblement parallèles à la découpe et/ou parallèles ou sensiblement parallèles aux lignes de pliure articulant la partie de fond aux parois correspondant aux éléments de feuille autoscellante, et à proximité de ces lignes de pliure.The linear fastening means may advantageously be parallel or substantially parallel to the cut and / or parallel or substantially parallel to the fold lines articulating the bottom portion to the walls corresponding to the self-sealing sheet elements, and close to these fold lines.

Chacun des moyens de fixation peut avantageusement être sur la paroi correspondante, ou bien encore à proximité de cette paroi, par exemple sur la partie de fond.Each of the fixing means may advantageously be on the corresponding wall, or even close to this wall, for example on the bottom part.

Avantageusement et de façon non limitative, l'un des moyens de fixation peut être proche d'une extrémité de la feuille autoscellante, tandis que la feuille autoscellante peut s'étendre au-delà de l'autre de ces moyens de fixation sur une bonne partie de sa longueur, par exemple sur au moins 30% de sa longueur et avantageusement sur au moins 40% de sa longueur.Advantageously and in a nonlimiting manner, one of the fastening means may be close to one end of the self-sealing sheet, while the self-sealing sheet may extend beyond the other of these fastening means on a good one. part of its length, for example over at least 30% of its length and advantageously over at least 40% of its length.

Avantageusement et de façon non limitative, lorsque les moyens de fixation sont linéaires, les moyens de fixation peuvent s'étendre suivant des directions parallèles ou sensiblement parallèles à la découpe de la feuille autoscellante.Advantageously and in a nonlimiting manner, when the fixing means are linear, the fixing means may extend in directions parallel or substantially parallel to the cutting of the self-sealing sheet.

Avantageusement et de façon non limitative, la découpe de la feuille peut être effectuée à proximité de l'autre des moyens de fixation, entre les moyens de fixation. Par exemple, la ligne de prédécoupe peut être à proximité de l'autre des moyens de fixation.Advantageously and in a nonlimiting manner, the cutting of the sheet can be performed near the other of the fixing means, between the fixing means. For example, the precut line may be close to the other fastening means.

La feuille autoscellante peut être fixée à l'élément en matériau semi-rigide de sorte que la face enduite de matériau autoscellant de ladite feuille soit en regard de l'élément en matériau semi-rigide, ou non.The self-sealing sheet may be fixed to the element made of semi-rigid material so that the face coated with self-sealing material of said sheet is facing the element made of semi-rigid material, or not.

Ainsi, l'élément de feuille autoscellante correspondant à l'autre des moyens de fixation, ou premier élément de feuille autoscellante lorsque la face enduite de la feuille est en regard du flan, est déjà superposé à la paroi correspondante, tandis que pour faire passer le deuxième élément de feuille autoscellante vers la position de superposition, on retourne ce deuxième élément de feuille autoscellante autour du moyen de fixation situé à proximité de l'extrémité de la feuille autoscellante, de sorte que la face enduite de composition autoscellante de ce deuxième élément est effectivement du côté de l'espace intérieur de l'emballage.Thus, the self-sealing sheet element corresponding to the other fastening means, or first self-sealing sheet element when the coated face of the sheet is facing the blank, is already superimposed on the corresponding wall, while for passing the second self-sealing sheet element to the position of overlaying, this second self-sealing sheet element is turned around the fastening means located near the end of the self-sealing sheet, so that the self-sealing composition-coated face of this second element is actually on the side of the interior space of packaging.

L'emballage peut avantageusement comprendre quatre parois.The package may advantageously comprise four walls.

Le fond peut avantageusement être de forme rectangulaire.The bottom may advantageously be of rectangular shape.

La feuille autoscellante peut s'étendre latéralement au-delà des parois, ou non.The self-sealing sheet may extend laterally beyond the walls, or not.

Avantageusement et de façon non limitative, chaque élément de feuille autoscellante peut avoir une longueur telle qu'en position de superposition, cet élément de feuille autoscellante s'étende au-delà d'un bord supérieur de la paroi correspondante, sur une portion de dépassement supérieur.Advantageously and in a nonlimiting manner, each self-sealing sheet element may have a length such that, in the superposition position, this self-sealing sheet element extends beyond an upper edge of the corresponding wall, over an overflow portion. superior.

Avantageusement et de façon non limitative, on peut prévoir de fixer, par exemple par un point ou un trait de colle, par exemple de colle repositionnable, au moins un élément de feuille autoscellante sur le coté extérieur de la paroi correspondante, au niveau de la portion de dépassement supérieur correspondante. Dit autrement, on replie contre la paroi la portion de l'élément de feuille autoscellante s'étendant au-delà du bord supérieur, et on colle cette portion à l'extérieur de l'emballage. Ceci peut permettre d'assurer un maintien en position de superposition, et donc de faciliter l'accès au fond de l'emballage.Advantageously and in a nonlimiting manner, it is possible to fix, for example by a point or a dash of glue, for example of repositionable glue, at least one self-sealing sheet element on the outer side of the corresponding wall, at the level of the corresponding overflow portion. In other words, the portion of the self-sealing sheet element extending over the upper edge is folded against the wall and this portion is glued to the outside of the package. This may make it possible to maintain the superposition position, and thus to facilitate access to the bottom of the package.

Il est en outre proposé un flan d'emballage, comprenant :

  • un flan en matériau semi rigide, tel que le carton ou le carton ondulé, comprenant une partie de fond et, au moins deux parois aptes à être dressées par rapport à la partie de fond, le flan étant conformé de sorte qu'après mise en volume, la partie de fond et les au moins deux parois définissent un espace intérieur pour recevoir un contenu, et

  • first and second self-sealing sheet members, each self-sealing sheet member comprising a paper sheet covered with self-sealing composition on one side only.

Les éléments de feuille autoscellante sont fixés au flan en matériau semi-rigide de façon à pouvoir passer d'une position de superposition à deux parois respectives, à une position repliée sur la partie de fond. En outre le flan d'emballage est agencé de sorte que lorsque les éléments de feuille autoscellante sont en position de superposition, le premier élément de feuille autoscellante ait sa face recouverte de composition autoscellante du coté de la paroi correspondant à cet élément de feuille et le deuxième élément de feuille autoscellante ait sa face non recouverte de composition autoscellante du coté du coté de la paroi correspondant à cet élément de feuille, afin que lorsque le premier élément de feuille autoscellante puis le deuxième élément de feuille autoscellante sont ensuite positionnés en position repliée, définissant ainsi une zone de recouvrement desdits éléments de feuille autoscellante, les deux faces recouvertes de composition autoscellante desdits éléments de feuille autoscellante soient en regard l'une de l'autre sur les parties de ces éléments de feuilles correspondant à la zone de recouvrement.The self-sealing sheet elements are fixed to the blank made of semi-rigid material so as to be able to pass from a superposition position to two respective walls, to a folded position on the part of the background. In addition, the packaging blank is arranged so that when the self-sealing sheet elements are in the superposition position, the first self-sealing sheet element has its self-sealing composition covered face on the side of the wall corresponding to this sheet element and the second self-sealing sheet element has its non-coated face with self-sealing composition on the side of the side of the wall corresponding to this sheet element, so that when the first self-sealing sheet element and the second self-sealing sheet element are then positioned in the folded position, thus defining a zone of overlap of said self-sealing sheet elements, the two sides covered with self-sealing composition of said self-sealing sheet elements are facing one another on the parts of these sheet elements corresponding to the overlap zone.

Un tel flan d'emballage peut permettre d'obtenir, après mise en volume, l'emballage décrit ci-dessus. Les éléments de feuille peuvent être encore joints l'un à l'autre, de façon à former une seule feuille autoscellante, ou non. En particulier, les éléments de feuille peuvent avoir été obtenus par découpe d'une seule feuille autoscellante.Such packaging blank can make it possible to obtain, after putting in volume, the packaging described above. The sheet elements may be further joined to each other to form a single self-sealing sheet or not. In particular, the sheet elements may have been obtained by cutting a single self-sealing sheet.

Il est en outre proposé un procédé de préparation d'un paquet, comprenant :

  • positioning the second self-sealing sheet member on the first self-sealing sheet member so that the two self-sealing composition covered sides of said self-sealing sheet elements are facing each other on the portions of said sheet elements corresponding to a recovery zone.

Le procédé peut préalablement comprendre une étape de dépose d'une feuille autoscellante munie de deux moyens de fixation sur un flan en matériau semi-rigide, ce flan étant conforme de façon à former après mise en volume l'élément en matériau semi-rigide, de sorte que la feuille autoscellante soit fixée à ce flan grâce à ces deux moyens de fixation.The method may first comprise a step of depositing a self-sealing sheet provided with two fastening means on a blank made of semi-rigid material, this blank being conforming so as to form after setting the volume of the semi-rigid material element, so that the self-sealing sheet is attached to this blank with these two fastening means.

Le procédé peut comprendre en outre une étape de découpe de la feuille autoscellante, la découpe étant située entre les moyens de fixation. Cette étape de découpe peut par exemple être effectuée manuellement, en tirant de part et d'autre d'une ligne de prédécoupe.The method may further comprise a step of cutting the self-sealing sheet, the cutout being located between the fixing means. This cutting step can for example be performed manually, pulling on both sides of a precut line.

L'un des moyens de fixation peut être situé à proximité de l'extrémité de la feuille autoscellante.One of the fastening means may be located near the end of the self-sealing sheet.

Le procédé peut comprendre en outre une étape de retournement de l'un des éléments de feuille autoscellante ainsi obtenus autour du moyen de fixation correspondant, avantageusement de l'élément de feuille autoscellante correspondant au moyen de fixation situé à proximité de l'extrémité de la feuille autoscellante. Ce retournement peut intervenir avant ou après la mise en volume de l'élément en matériau semi-rigide.The method may further comprise a step of turning one of the self-sealing sheet elements thus obtained around the corresponding fastening means, advantageously the self-sealing sheet element corresponding to the fastening means located near the end of the self-sealing leaf. This reversal may occur before or after the setting of the volume of the semi-rigid material element.

Des références identiques peuvent être utilisées d'une figure à l'autre pour désigner des éléments identiques ou similaires.Identical references can be used from one figure to another to designate identical or similar elements.

Sur ces figures, aucun volet venant refermer le dessus de l'emballage n'est représenté. On pourrait par exemple prévoir un élément de couvercle séparé.In these figures, no flap that closes the top of the package is shown. For example, a separate lid element could be provided.

En référence à la figure 1, un flan d'emballage 1 comprend un flan 2 en matériau semi-rigide, ici en carton ondulé. Ce flan 2 comprend une partie de fond 3, et des parois 4, 5 de part et d'autre de la partie de fond. Les parois 4 et 5 sont articulées à la partie de fond 3 par des lignes de pliure respectives 14, 15.With reference to the figure 1 , a packaging blank 1 comprises a blank 2 of semi-rigid material, here corrugated cardboard. This blank 2 comprises a bottom portion 3, and walls 4, 5 on either side of the bottom portion. The walls 4 and 5 are hinged to the bottom portion 3 by respective fold lines 14, 15.

Le flan 2 comprend en outre, sur les deux autres côtés de la partie de fond rectangulaire 3, deux parois latérales 104, 105. Chaque paroi latérale 104, 105 est articulée à la partie de fond 3 par des lignes de pliure respective 114, 115.The blank 2 further comprises, on the two other sides of the rectangular bottom portion 3, two side walls 104, 105. Each side wall 104, 105 is hinged to the bottom portion 3 by respective fold lines 114, 115 .

Les quatre parois 4, 5, 104, 105 sont destinées à être dressées par rapport au fond 3 de façon à définir un espace intérieur pour recevoir un contenu.The four walls 4, 5, 104, 105 are intended to be erected relative to the bottom 3 so as to define an interior space for receiving a content.

Dans cet exemple sont articulées aux parois 4, 5 des volets d'extrémité 106, 107, 108, 109. Chaque volet 106, 107, 108, 109 est articulé à la paroi correspondante 4, 5 par une ligne de pliure 116, 117, 118, 119 perpendiculaire aux lignes de pliures 14, 15 articulant la partie de fond 3 aux parois 4, 5. Plus précisément les lignes de pliures 116, 119 sont, à une épaisseur de flan près, dans la continuité de la ligne de pliure 115 articulant la partie de fond à la paroi additionnelle 105. Les lignes de pliure 117, 118 sont, à une épaisseur de flan près, dans la continuité de la ligne de pliure 114 articulant la partie de fond 3 à la paroi additionnelle 104.In this example are hinged to the walls 4, 5 end flaps 106, 107, 108, 109. Each flap 106, 107, 108, 109 is articulated to the corresponding wall 4, 5 by a fold line 116, 117, 118, 119 perpendicular to the fold lines 14, 15 articulating the bottom portion 3 to the walls 4, 5. More precisely the fold lines 116, 119 are, to a thickness of blank, in the continuity of the fold line 115 articulating the bottom portion to the additional wall 105. The fold lines 117, 118 are, at a thickness flan close, in the continuity of the fold line 114 articulating the bottom portion 3 to the additional wall 104.

Dans d'autres modes de réalisation, on pourrait prévoir des volets additionnels articulés aux parois 4, 5, 104 et/ou 105 de façon à former le dessus de l'emballage après mise en volume.In other embodiments, there may be additional flaps hinged to the walls 4, 5, 104 and / or 105 so as to form the top of the package after setting volume.

Sur ce flan 2 est collée une feuille autoscellante 10 grâce à deux moyens de fixation 11, 12 et quatre moyens de positionnement 201.On this blank 2 is glued a self-sealing sheet 10 by two fixing means 11, 12 and four positioning means 201.

Ces moyens de fixation 11, 12 comprennent deux lignes de colle non repositionnables. Ce collage peut être effectué de façon automatisée.These fastening means 11, 12 comprise two non-repositionable glue lines. This collage can be performed automatically.

Les lignes de colle 11 12, sont parallèles ou sensiblement parallèles aux lignes de pliure 14, 15. La ligne de colle 11 est située à proximité d'une extrémité 101 de la feuille autoscellante.The glue lines 11 12 are parallel or substantially parallel to the fold lines 14, 15. The glue line 11 is located near an end 101 of the self-sealing sheet.

Le moyens de positionnement comprennent des points de colle repositionnable 201.The positioning means comprise repositionable adhesive points 201.

La feuille autoscellante comprend une feuille de papier recouverte de composition autoscellante sur une face seulement. Le papier de la feuille autoscellante peut avoir été obtenu par recyclage de papier ou de carton.The self-sealing sheet comprises a sheet of paper covered with self-sealing composition on one side only. The self-sealing paper may have been obtained by recycling paper or cardboard.

La feuille autoscellante a été préalablement prédécoupée, de sorte qu'une ligne de prédécoupe 200 vient séparer cette feuille en deux parties.The self-sealing sheet has been previously precut, so that a pre-cut line 200 separates this sheet into two parts.

La feuille autoscellante 10 est positionnée lors du collage de sorte que sa face recouverte de composition autoscellante, soit en regard du flan 2.The self-sealing sheet 10 is positioned during bonding so that its face covered with self-sealing composition, is opposite the blank 2.

Puis, comme illustré sur la figure 2A, l'extrémité de la feuille autoscellante 10 s'étendant au-delà de la paroi 5, est repliée sur le côté du flan 2 opposé au coté visible sur la figure 1. On peut prévoir de manipuler cette extrémité 13 par des moyens de préhension appliquant un vide d'air du type connus de l'homme du métier.Then, as illustrated on the Figure 2A , the end of the self-sealing sheet 10 extending beyond the wall 5, is folded on the side of the blank 2 opposite the visible side on the figure 1 . It is possible to manipulate this end 13 by gripping means applying a vacuum of air of the type known to those skilled in the art.

Dans le mode de réalisation représenté, des moyens de fixation repositionnables 20 permettent de maintenir en place cette partie 13 de la feuille autoscellante 10.In the embodiment shown, repositionable fixing means 20 make it possible to hold this portion 13 of the self-sealing sheet 10 in place.

Puis la feuille autoscellante 10 est séparée en deux, manuellement, au niveau de la ligne de prédécoupe 200. Une ligne de découpe 21, correspondant à la ligne de prédécoupe 200, sépare ces deux parties l'une de l'autre.Then the self-sealing sheet 10 is separated in two, manually, at the precut line 200. A cutting line 21, corresponding to the precut line 200, separates these two parts from one another.

Alternativement, la feuille autoscellante 10 pourrait être découpée au moyen d'un cutter ou autre, selon une ligne de découpe située sensiblement au niveau de la ligne de pliure référencée 15 sur les figures.Alternatively, the self-sealing sheet 10 could be cut by means of a cutter or the like, along a cutting line located substantially at the fold line referenced in the figures.

Cette étape de séparation conduit à former deux éléments de feuille autoscellante 7 et 8 fixés au flan en carton ondulé par deux lignes de colle 11, 12 respectives. Pour chacun de ces éléments 7, 8, les lignes de colles sont situées prés d'une extrémité de cet élément 7, 8.This separation step leads to form two self-sealing sheet elements 7 and 8 attached to the corrugated cardboard blank by two lines of adhesive 11, 12 respectively. For each of these elements 7, 8, the glue lines are located near one end of this element 7, 8.

En référence à la figure 2C, on a mis en volume le flan en carton ondulé, de façon à former un élément en carton ondulé 52, avec cette fois les parois 4, 5 et également les parois 104, 105 (non visibles sur la figure 2C), dressées par rapport à la partie de fond 3.With reference to the Figure 2C , the corrugated cardboard blank was made to volume, so as to form a corrugated cardboard element 52, this time with the walls 4, 5 and also the walls 104, 105 (not visible on the Figure 2C ), raised with respect to the bottom portion 3.

En particulier, les volets 106, 107 (non visibles sur la figure 2C) sont dressés par rapport à la paroi 4 et collés aux parois 104, 105 respectives. De la même façon, les volets 108, 109 (non visibles sur la figure 2C) sont dressés par rapport à la paroi 5 et collés aux parois 104, 105 respectifs, afin de maintenir les parois 4, 5, 104, 105, dressées par rapport au fond 3.In particular, the flaps 106, 107 (not visible on the Figure 2C ) are raised relative to the wall 4 and bonded to the respective walls 104, 105. In the same way, the flaps 108, 109 (not visible on the Figure 2C ) are raised with respect to the wall 5 and bonded to the respective walls 104, 105, so as to maintain the walls 4, 5, 104, 105, erected relative to the bottom 3.

Dans un premier temps, comme représenté sur la figure 2C, des moyens de préhension automatiques par exemple basés sur vide d'air ou autre, ou bien encore manuels, permettent de saisir la feuille autoscellante 8 et de l'amener contre la paroi 4. La feuille autoscellante est ainsi repliée à 180° au niveau de la ligne de colle 11.At first, as represented on the Figure 2C automatic gripping means for example based on vacuum or other air, or else manual, can capture the self-sealing sheet 8 and bring it against the wall 4. The self-sealing sheet is thus folded to 180 ° at the of the glue line 11.

Dans ce mode de réalisation, comme représenté sur la figue 2D, des moyens de fixation repositionnables 22, par exemple un point de colle repositionnable, permet de maintenir l'élément de feuille autoscellante 8 dans cette position de superposition à la paroi 4.In this embodiment, as shown in FIG. 2D, repositionable fixing means 22, for example a repositionable glue point, makes it possible to maintain the self-sealing sheet element 8 in this superposition position to the wall 4.

Ainsi, comme illustré sur la figure 2D les éléments de feuille autoscellante 7 et 8 sont alors dans une position de superposition aux parois respectives 5, 4, permettant ainsi d'accéder à l'espace intérieur 23 de l'emballage 50.So, as illustrated on the 2D figure the self-sealing sheet elements 7 and 8 are then in a position of superposition to the respective walls 5, 4, thus allowing access to the interior space 23 of the package 50.

Un contenu 60 peut alors être déposé à l'intérieur de cet emballage 50.A content 60 can then be deposited inside this package 50.

Comme lors de la dépose de la feuille autoscellante 10, cette feuille avait été positionnée de façon à ce que la face de la feuille recouverte de composition autoscellante soit en regard du flan en carton 2, le premier élément de feuille autoscellante 7, a sa face recouverte de composition autoscellante 71 en regard de la paroi 5. En revanche, le deuxième élément de la feuille autoscellante 8 a été retourné autour du moyen de fixation 11, de sorte que la face 81 de ce deuxième élément de feuille autoscellante 8 qui est recouverte de composition autoscellante est tournée vers l'espace intérieur 23 de l'emballage 50.As when removing the self-sealing sheet 10, this sheet had been positioned so that the face of the sheet covered with self-sealing composition is facing the cardboard blank 2, the first self-sealing sheet element 7, has its face. covered with In contrast, the second element of the self-sealing sheet 8 has been turned around the fastening means 11, so that the face 81 of this second self-sealing sheet element 8 which is covered with composition self-sealing is turned to the inner space 23 of the package 50.

Comme représenté sur les figures 2D et 2E, le premier élément de feuille autoscellante 7 est rabattu contre le contenu 60. La face de l'élément de feuille 7 qui est en contact ou en regard avec le contenu 60 est la face 82 non recouverte de composition autoscellante.As shown on Figures 2D and 2E the first self-sealing foil member 7 is folded back against the contents 60. The face of the foil member 7 which is in contact or facing the contents 60 is the face 82 not covered with self-sealing composition.

Puis, dans un deuxième temps, c'est le deuxième élément de feuille autoscellante 8 qui est rabattu vers le contenu, sur le premier élément de feuille autoscellante.Then, in a second step, it is the second self-sealing sheet element 8 which is folded towards the content, on the first self-sealing sheet element.

On peut prévoir de manipuler les éléments 7, 8 avec des moyens de préhension automatisés, de sorte que le positionnement de ces éléments peut être effectuée de façon automatisée.It is possible to manipulate the elements 7, 8 with automated gripping means, so that the positioning of these elements can be performed in an automated manner.

Les deux éléments de feuille autoscellante 7, 8 ainsi rabattus définissent une zone de recouvrement 51. Les deux faces recouvertes de composition autoscellante des éléments 7 8 sont en regard l'une de l'autre sur les parties de ces éléments 7 8 correspondant à la zone de recouvrement 51. Ainsi, les éléments 7, 8 sont fixés l'un à l'autre de par la présence de composition autoscellante sur toute une zone de recouvrement, quelle que soit sa position.The two self-sealing sheet elements 7, 8 thus folded define a covering zone 51. The two faces covered with self-sealing composition of the elements 78 are facing each other on the parts of these elements 78 corresponding to the Thus, the elements 7, 8 are fixed to each other by the presence of self-sealing composition over an entire overlap zone, regardless of its position.

On peut éventuellement prévoir d'exercer une pression sur ces éléments 7, 8, en les poussant par exemple suivant une direction verticale, dans un sens vers les articules conditionnés 60, afin de s'assurer de l'adhésion des éléments 7, 8.It may be possible to exert pressure on these elements 7, 8, pushing them for example in a vertical direction, in one direction to the packaged articules 60, to ensure the adhesion of the elements 7, 8.

Les éléments 7, 8 permettent de protéger et de maintenir en place les articles conditionnés 60.The elements 7, 8 make it possible to protect and keep in place the packaged articles 60.
