Definitions

  • the invention relates to the field of packaging packs comprising several pots grouped one above the other, by means of cardboard packaging.
  • the subject of the invention is more precisely an intermediate element of a packaging of a pack.
  • Packs comprising a cardboard blank forming a packaging of at least two layers of pots.
  • the top pots of the top layer rest by their bottom walls on the closures of the bottom pots of the bottom layer.
  • the upper layer is therefore carried by the lower layer.
  • the top pots are not sufficiently well held in the event of sudden movement in the packaging. This results in poor support capable of causing the top pots to move relative to the bottom pots, and possibly a separation of the pack.
  • intermediate elements are known.
  • Such spacers comprise retaining elements respectively arranged partially around the side walls of the top pots in the vicinity of their bottom walls.
  • the top pots are thus spaced and wedged together, and less likely to move relative to the pots below.
  • the document FR 2684078 describes an example of such an intermediate element.
  • the intermediate elements are often not strong enough so that too abrupt displacement of the pack is liable to deteriorate the retaining elements of the intermediate element and then render it inoperative.
  • the pots are not maintained satisfactorily, and in particular equivalent, in all directions.
  • the invention thus aims to obtain an intermediate element and, more generally, a packaging of a pack, in which the top pots are maintained satisfactorily with respect to the bottom pots.
  • the top pots are maintained satisfactorily.
  • the fact of having the second openings at a distance from the central panel allows, once the intermediate element has been shaped, that the first openings surround the side walls of the top pots with a distance from their bottom walls. .
  • the top pots are particularly well maintained.
  • each second opening is delimited by at least a first cut line and a second cut line, the first cut line being suitable and intended to come into abutment with a bottom pot.
  • the first and second side panels are identical to each other.
  • first side panel, the central panel and the second side panel are arranged one after the other in the longitudinal direction.
  • first and second side panels are articulated relative to the central panel respectively along fold lines extending in a transverse direction perpendicular to the longitudinal direction.
  • the central panel of the intermediate element is raised by a spacing with respect to the pots below.
  • each first opening of the intermediate element completely surrounds the side wall of a top pot.
  • each first opening of the intermediate element is suitable and intended to stop a top pot on its side wall, in the vicinity of its bottom wall.
  • the packaging also comprises a blank set in volume to surround the bottom pots and the top pots.
  • the intermediate element is shaped by folding the first and second side panels relative to the central panel, the flank maintaining the shaped intermediate element.
  • the intermediate element is kept in shape by the sidewall, which makes it possible to prevent the intermediate element from being able to be moved once the pack has been formed.
  • the invention relates to a cardboard insert 1, flat, intended to hold the jars 2 of a pack 20, as illustrated in the drawings. figures 1A and 1B .
  • interlayer it is understood that the element 1 is suitable and intended to be placed at, or in its vicinity of, the junction of two layers of pots 2 of the pack 20.
  • cardboard is meant a layered material, such as that commonly used or suitable for the indicated destination. Such a cardboard should be neither too rigid nor too flexible. It must be able to be folded at the location of fold lines, such as creased lines and / or cut lines, provided for this purpose.
  • pack should be understood to mean a batch formed of several pots 2 presented grouped in superimposed layers, in longitudinal rows and / or in transverse rows, in a packaging, so as to form a unitary assembly, intended to be stored, handled, moved, offered for sale and sold as such.
  • a pot 2 comprises a bottom wall 3a, a side wall closed on itself 3b and an opening opposite the bottom wall 3a with top closure 4.
  • a pot 2 is in the form of a cylinder or of a truncated cone and comprises a flange 5 transverse towards its upper opening, the top closure 4 being a flat cover secured to and on the flange 5.
  • the generatrix of the side wall 3b is a line other than a straight line, having a more or less complex shape, and the directing curve is other than a circle, being for example a curvilinear square with rounded corners.
  • Such a pot 2 can stand upright by resting on its bottom wall 3a forming a seat.
  • the pots 2 are individualized or they are interconnected, for example by their flanges 5, so as to form a plate of pots 2.
  • the pots 2 are similar, most especially. identical, and they are filled with a certain content, identical or not for the different jars 2, and closed.
  • a pot 2 is made of thermoformed plastic and it has a certain strength allowing it to be self-supporting, but the pot can be made of other materials and by other methods.
  • a pot 2 is typically intended to contain a content that is homogeneous or not, having a more or less fluid overall condition, which does not exclude the presence of more or less solid pieces.
  • Such content is for example a milk product or a dessert, this list not being exhaustive.
  • the pot 2 is intended to receive a dose of such content for individual and unit use, for example of the order of a hundred grams and, in this case, it may have a height of the order of a few centimeters and fit laterally in a cylinder whose diameter is also of the order of a few centimeters.
  • the pot 2, intended for a minidose is smaller or, on the contrary, intended for a larger dose, is larger.
  • the intermediate element 1 is of generally rectangular shape and it is limited by two free edges 6 in the longitudinal direction L and by two free edges 7 in the transverse direction T.
  • the longitudinal direction L and the transverse direction T cross perpendicularly the one with the other at a point O in the center of the spacer 1.
  • the intermediate element 1 comprises, arranged one after the other in the longitudinal direction L, and between the two free edges 6, a first side panel 8, a central panel 9 and a second side panel 10.
  • panel should be understood to mean a flat piece in the form of a layer, made of cardboard in this case, delimited by a border comprising fold lines, such as grooved lines and / or cut lines.
  • the intermediate element 1 is preferably such that the two side panels 8, 10 are identical to each other.
  • the spacer 1 also includes fold lines, such as transverse direction grooved lines T.
  • Grooved lines are well known in the field of packaging and cardboard and allow two adjacent panels to be relatively folded into one. predefined location. Such creasing lines are formed by using a creasing tool. It is understood that the expression “grooved line” is to be understood in the widest sense as meaning that the line is suitable and intended for the relative folding of two adjacent panels.
  • the intermediate element 1 comprises two fold lines 11, 12 respectively between the central panel 9 and the two side panels 8, 10.
  • the two fold lines 11, 12 are alternating cutting lines.
  • alternating cutting it should be understood that on the line, the cardboard is regularly and alternately cut through and then not cut, and so on, so as to create a mixed line.
  • the two side panels 8, 10 are thus articulated relative to the central panel 9 along the fold lines 11, 12, advantageously parallel to one another. These two fold lines 11, 12 are thus suitable and intended for the relative folding of the side panels 8, 10 with respect to the central panel 9 in order to shape the intermediate element 1.
  • the two side panels 8, 10 form with the central panel 9 an angle ⁇ , in particular obtuse, for example of the order of 120 degrees, as illustrated in figure 5 .

  • Each first opening 13 advantageously has a circular shape, or more generally a shape corresponding to the cross-sectional shape of a side wall 3b of pot 2.
  • Each first opening 13 is however slightly wider than the side wall 3b of a pot 2. , in particular in the vicinity of its bottom wall 3a, so that a pot can be arranged in a first opening 13, while leaving a space E between the intermediate element 1 and the side wall 3b of the pot 2 disposed in the first opening 13, shown on figure 5 .
  • the side panels 8, 10 also include second openings 14, advantageously through.

Description

L'invention concerne le domaine de l'emballage des packs comprenant plusieurs pots groupés les uns au-dessus des autres, grâce à un conditionnement en carton.The invention relates to the field of packaging packs comprising several pots grouped one above the other, by means of cardboard packaging.

L'invention a plus précisément pour objet un élément intercalaire d'un conditionnement d'un pack.The subject of the invention is more precisely an intermediate element of a packaging of a pack.

On connait des packs comprenant un flan en carton formant un conditionnement d'au moins deux couches de pots. Les pots de dessus de la couche supérieure reposent par leurs parois de fond sur les fermetures des pots de dessous de la couche inférieure. La couche supérieure est donc portée par la couche inférieure.Packs are known comprising a cardboard blank forming a packaging of at least two layers of pots. The top pots of the top layer rest by their bottom walls on the closures of the bottom pots of the bottom layer. The upper layer is therefore carried by the lower layer.

Toutefois, de tels packs n'apportent pas entièrement satisfaction.However, such packs are not entirely satisfactory.

En particulier, dans de tels packs, les pots de dessus ne sont pas suffisamment bien tenus en cas de déplacement brusque dans le conditionnement. Il en résulte un mauvais maintien susceptible d'entrainer un déplacement des pots de dessus relativement aux pots de dessous, et éventuellement une désolidarisation du pack.In particular, in such packs, the top pots are not sufficiently well held in the event of sudden movement in the packaging. This results in poor support capable of causing the top pots to move relative to the bottom pots, and possibly a separation of the pack.

A cet effet, on connait des éléments intercalaires. De tels intercalaires comprennent des éléments de maintien respectivement disposés partiellement autour des parois latérales des pots de dessus au voisinage de leurs parois de fond. Les pots de dessus sont ainsi espacés et calés entre eux, et moins susceptibles de se déplacer relativement aux pots de dessous. Le document FR 2684078 décrit un exemple d'un tel élément intercalaire.For this purpose, intermediate elements are known. Such spacers comprise retaining elements respectively arranged partially around the side walls of the top pots in the vicinity of their bottom walls. The top pots are thus spaced and wedged together, and less likely to move relative to the pots below. The document FR 2684078 describes an example of such an intermediate element.

Le document JP2007269334 décrit quant à lui un intercalaire selon le préambule de la revendication 1.The document JP2007269334 describes for its part an insert according to the preamble of claim 1.

Toutefois, ces éléments intercalaires n'apportent pas entièrement satisfaction.However, these intermediate elements are not entirely satisfactory.

En particulier, les éléments intercalaires ne sont souvent pas assez robustes de sorte qu'un déplacement trop brusque du pack est susceptible de détériorer les éléments de maintien de l'élément intermédiaire et le rendre alors inopérant. En outre, les pots ne sont pas maintenus de façon satisfaisante, et notamment équivalente, dans toutes les directions.In particular, the intermediate elements are often not strong enough so that too abrupt displacement of the pack is liable to deteriorate the retaining elements of the intermediate element and then render it inoperative. In addition, the pots are not maintained satisfactorily, and in particular equivalent, in all directions.

L'invention vise ainsi à obtenir un élément intercalaire et, plus généralement, un conditionnement d'un pack, dans lequel les pots de dessus sont maintenus de façon satisfaisante par rapport aux pots de dessous.The invention thus aims to obtain an intermediate element and, more generally, a packaging of a pack, in which the top pots are maintained satisfactorily with respect to the bottom pots.

Ainsi, l'invention concerne un élément intercalaire en carton, à plat, destiné au maintien de pots dans un pack, le pack comprenant des pots de dessous d'une couche inférieure et des pots de dessus d'une couche supérieure, l'élément intercalaire comprenant au moins un premier panneau de côté, un panneau central et un second panneau de côté. En outre :

  • le panneau central comprend des première ouvertures, chaque première ouverture étant apte et destinée à entourer un pot de dessus,
  • les premier et second panneaux de côté comprennent des secondes ouvertures, chaque seconde ouverture étant apte et destinée à venir en butée avec un pot de dessous, et selon l'invention
  • les secondes ouvertures sont disposées à une distance du panneau central selon une direction longitudinale.
Thus, the invention relates to an intermediate cardboard element, flat, intended for maintaining jars in a pack, the pack comprising bottom jars of a lower layer and top jars of an upper layer, the element interlayer comprising at least a first side panel, a central panel and a second side panel. In addition :
  • the central panel comprises first openings, each first opening being suitable and intended to surround a top pot,
  • the first and second side panels comprise second openings, each second opening being suitable and intended to come into abutment with a pot from below, and according to the invention
  • the second openings are arranged at a distance from the central panel in a longitudinal direction.

Grâce à ces dispositions, les pots de dessus sont maintenus de façon satisfaisante. En particulier, le fait d'avoir les secondes ouvertures à distance du panneau central permet, une fois l'élément intercalaire mis en forme, que les première ouvertures entourent les parois latérales des pots de dessus avec un écartement par rapport à leurs parois de fond. Ainsi, les pots de dessus sont particulièrement bien tenus.Thanks to these arrangements, the top pots are maintained satisfactorily. In particular, the fact of having the second openings at a distance from the central panel allows, once the intermediate element has been shaped, that the first openings surround the side walls of the top pots with a distance from their bottom walls. . Thus, the top pots are particularly well maintained.

Selon une réalisation, chaque seconde ouverture est délimitée par au moins une première ligne découpée et une seconde ligne découpée, la première ligne découpée étant apte et destinée à venir en butée avec un pot de dessous.According to one embodiment, each second opening is delimited by at least a first cut line and a second cut line, the first cut line being suitable and intended to come into abutment with a bottom pot.

Selon une autre réalisation, les premier et second panneaux de côté sont identiques l'un de l'autre.According to another embodiment, the first and second side panels are identical to each other.

Selon une autre réalisation, le premier panneau de côté, le panneau central et le second panneau de côté sont disposés les uns à la suite des autres selon la direction longitudinale. Selon une autre réalisation, les premier et second panneaux de côté sont articulés par rapport au panneau central respectivement le long de lignes de pliage s'étendant selon une direction transversale perpendiculaire à la direction longitudinale.According to another embodiment, the first side panel, the central panel and the second side panel are arranged one after the other in the longitudinal direction. According to another embodiment, the first and second side panels are articulated relative to the central panel respectively along fold lines extending in a transverse direction perpendicular to the longitudinal direction.

L'invention concerne également un pack comprenant :

  • une couche inférieure comprenant des pots de dessous et une couche supérieure comprenant des pots de dessus, les pots de dessus étant disposés sur les pots de dessous, chaque pot comprenant une paroi de fond et une paroi latérale, et
  • un conditionnement comprenant au moins un élément intercalaire selon l'invention.
The invention also relates to a pack comprising:
  • a lower layer comprising bottom pots and an upper layer comprising top pots, the top pots being disposed on the bottom pots, each pot including a bottom wall and a side wall, and
  • a packaging comprising at least one intermediate element according to the invention.

Selon une réalisation, le panneau central de l'élément intercalaire est surélevé d'un écartement par rapport aux pots de dessous.According to one embodiment, the central panel of the intermediate element is raised by a spacing with respect to the pots below.

Selon une autre réalisation, chaque première ouverture de l'élément intercalaire entoure complètement la paroi latérale d'un pot de dessus.According to another embodiment, each first opening of the intermediate element completely surrounds the side wall of a top pot.

Ainsi, les pots sont maintenus quel que soit la direction de déplacement du pack.Thus, the pots are maintained regardless of the direction of movement of the pack.

Selon une autre réalisation, chaque première ouverture de l'élément intercalaire est apte et destinée à arrêter un pot de dessus sur sa paroi latérale, au voisinage de sa paroi de fond.According to another embodiment, each first opening of the intermediate element is suitable and intended to stop a top pot on its side wall, in the vicinity of its bottom wall.

Selon une autre réalisation, le conditionnement comprend également un flan mis en volume pour entourer les pots de dessous et les pots de dessus.According to another embodiment, the packaging also comprises a blank set in volume to surround the bottom pots and the top pots.

Selon une autre réalisation, l'élément intercalaire est mis en forme par pliage des premier et second panneaux de côté par rapport au panneau central, le flanc maintenant l'élément intercalaire mis en forme.According to another embodiment, the intermediate element is shaped by folding the first and second side panels relative to the central panel, the flank maintaining the shaped intermediate element.

Ainsi, l'élément intercalaire est maintenu en forme par le flanc, ce qui permet d'éviter que l'élément intercalaire ne puisse être déplacé une fois le pack constitué.Thus, the intermediate element is kept in shape by the sidewall, which makes it possible to prevent the intermediate element from being able to be moved once the pack has been formed.

L'invention concerne enfin un procédé de constitution d'un pack, dans lequel :

  • on dispose d'un élément intercalaire selon l'invention, d'un flan, de pots de dessous et de pots de dessus destinés à faire partie du pack, chaque pot comprenant une paroi de fond et une paroi latérale,
  • on dispose, successivement ou simultanément, les pots de dessous en une couche inférieure sur le flan,
  • on dispose l'élément intercalaire sur la couche de pots de dessous,
  • on dispose, successivement ou simultanément, les pots de dessus en une couche supérieure sur les pots de dessous, et
  • on met en volume le flan autour des pots de dessous et des pots de dessus de sorte à maintenir en forme l'élément intercalaire.
Finally, the invention relates to a method of constituting a pack, in which:
  • there is an intermediate element according to the invention, a blank, bottom pots and top pots intended to form part of the pack, each pot comprising a bottom wall and a side wall,
  • the bottom pots are placed successively or simultaneously in a lower layer on the blank,
  • the spacer is placed on the bottom layer of pots,
  • the top pots are placed, successively or simultaneously, in an upper layer on the bottom pots, and
  • the blank is put in volume around the bottom pots and the top pots so as to keep the intermediate element in shape.

Les différentes réalisations de l'invention qui viennent d'être décrits peuvent être mis en œuvre indépendamment les unes des autres ou en combinaison les unes avec les autres.The various embodiments of the invention which have just been described can be implemented independently of one another or in combination with one another.

On décrit maintenant brièvement les figures des dessins.

L'invention concerne un élément intercalaire 1 en carton, à plat, destiné au maintien de pots 2 d'un pack 20, tel qu'illustré sur les figures 1A et 1B.The invention relates to a cardboard insert 1, flat, intended to hold the jars 2 of a pack 20, as illustrated in the drawings. figures 1A and 1B .

Par « intercalaire », on comprend que l'élément 1 est apte et destiné à être disposé au niveau de, ou à son voisinage de, la jonction de deux couches de pots 2 du pack 20.By “interlayer”, it is understood that the element 1 is suitable and intended to be placed at, or in its vicinity of, the junction of two layers of pots 2 of the pack 20.

Par « carton », il faut comprendre un matériau en couche, tel que celui couramment utilisé ou adapté pour la destination indiquée. Un tel carton ne doit être ni trop rigide, ni trop souple. Il doit pouvoir être plié à l'endroit de lignes de pliage, telles que des lignes rainées et/ou des lignes découpées, prévues à cet effet.By "cardboard" is meant a layered material, such as that commonly used or suitable for the indicated destination. Such a cardboard should be neither too rigid nor too flexible. It must be able to be folded at the location of fold lines, such as creased lines and / or cut lines, provided for this purpose.

Par « à plat », il faut comprendre que l'élément intercalaire 1 est déployé, de sorte à se trouver au moins sensiblement dans un seul et même plan P.By “flat”, it should be understood that the intermediate element 1 is deployed, so as to be at least substantially in one and the same plane P.

Le terme « pack » doit être compris comme signifiant un lot formé de plusieurs pots 2 présentés groupés en couches superposées, en rangées longitudinales et/ou en rangées transversales, dans un conditionnement, de sorte à former un ensemble unitaire, destiné à être stocké, manipulé, déplacé, mis à la vente et vendu comme tel.The term "pack" should be understood to mean a batch formed of several pots 2 presented grouped in superimposed layers, in longitudinal rows and / or in transverse rows, in a packaging, so as to form a unitary assembly, intended to be stored, handled, moved, offered for sale and sold as such.

Un pot 2 comprend une paroi de fond 3a, une paroi latérale fermée sur elle-même 3b et une ouverture opposée à la paroi de fond 3a avec fermeture de dessus 4.A pot 2 comprises a bottom wall 3a, a side wall closed on itself 3b and an opening opposite the bottom wall 3a with top closure 4.

Dans une réalisation, un pot 2 est en forme de cylindre ou de tronc de cône et comporte une collerette 5 transversale vers son ouverture supérieure, la fermeture de dessus 4 étant un opercule plat solidarisé à et sur la collerette 5. Dans d'autres réalisations, la génératrice de la paroi latérale 3b est une ligne autre qu'une ligne droite, ayant une forme plus ou moins complexe, et la courbe directrice est autre qu'un cercle, étant par exemple un carré curviligne à coins arrondis. Un tel pot 2 peut tenir droit en reposant sur sa paroi de fond 3a formant assise.In one embodiment, a pot 2 is in the form of a cylinder or of a truncated cone and comprises a flange 5 transverse towards its upper opening, the top closure 4 being a flat cover secured to and on the flange 5. In other embodiments , the generatrix of the side wall 3b is a line other than a straight line, having a more or less complex shape, and the directing curve is other than a circle, being for example a curvilinear square with rounded corners. Such a pot 2 can stand upright by resting on its bottom wall 3a forming a seat.

Selon les cas, les pots 2 sont individualisés ou bien ils sont reliés entre eux, par exemple par leurs collerettes 5, de sorte à former une plaquette de pots 2. Dans le contexte de l'invention, les pots 2 sont analogues, tout spécialement identiques, et ils sont emplis d'un certain contenu, identique ou non pour les différents pots 2, et fermés.Depending on the case, the pots 2 are individualized or they are interconnected, for example by their flanges 5, so as to form a plate of pots 2. In the context of the invention, the pots 2 are similar, most especially. identical, and they are filled with a certain content, identical or not for the different jars 2, and closed.

Dans une réalisation, un pot 2 est réalisé en matière plastique thermoformée et il présente une certaine tenue lui permettant d'être autoportant, mais le pot peut être réalisé en d'autres matériaux et par d'autres procédés.In one embodiment, a pot 2 is made of thermoformed plastic and it has a certain strength allowing it to be self-supporting, but the pot can be made of other materials and by other methods.

Un pot 2 est destiné typiquement à contenir un contenu homogène ou non, présentant un état d'ensemble plus ou moins fluide, ce qui n'exclut pas la présence de morceaux plus ou moins solides. Un tel contenu est par exemple un produit lacté ou un dessert, cette liste n'étant pas limitative.A pot 2 is typically intended to contain a content that is homogeneous or not, having a more or less fluid overall condition, which does not exclude the presence of more or less solid pieces. Such content is for example a milk product or a dessert, this list not being exhaustive.

Dans une réalisation, le pot 2 est destiné à recevoir une dose d'un tel contenu à usage individuel et unitaire, par exemple de l'ordre d'une centaine de grammes et, dans ce cas, il peut avoir une hauteur de l'ordre de quelques centimètres et s'inscrire latéralement dans un cylindre dont le diamètre est également de l'ordre de quelques centimètres. Dans d'autres réalisations, le pot 2, destiné à une minidose, est plus petit ou, au contraire, destiné à une dose plus importante, est plus grand.In one embodiment, the pot 2 is intended to receive a dose of such content for individual and unit use, for example of the order of a hundred grams and, in this case, it may have a height of the order of a few centimeters and fit laterally in a cylinder whose diameter is also of the order of a few centimeters. In other embodiments, the pot 2, intended for a minidose, is smaller or, on the contrary, intended for a larger dose, is larger.

On peut définir, relativement à l'élément intercalaire 1 à plat dans le plan P, une direction longitudinale L et une direction transversale T, perpendiculaires entre elles, ainsi qu'une direction Z perpendiculaire ou sensiblement perpendiculaire au plan P.A longitudinal direction L and a transverse direction T, perpendicular to each other, as well as a direction Z perpendicular or substantially perpendicular to the plane P.

L'élément intercalaire 1 est de forme générale rectangulaire et il est limité par deux bords libres 6 dans la direction longitudinale L et par deux bords libres 7 dans la direction transversale T. La direction longitudinale L et la direction transversale T se croisent perpendiculairement l'une avec l'autre en un point O au centre de l'élément intercalaire 1.The intermediate element 1 is of generally rectangular shape and it is limited by two free edges 6 in the longitudinal direction L and by two free edges 7 in the transverse direction T. The longitudinal direction L and the transverse direction T cross perpendicularly the one with the other at a point O in the center of the spacer 1.

L'élément intercalaire 1 comprend, disposés les uns à la suite des autres dans la direction longitudinale L, et entre les deux bords libres 6, un premier panneau de côté 8, un panneau central 9 et un second panneau de côté 10.The intermediate element 1 comprises, arranged one after the other in the longitudinal direction L, and between the two free edges 6, a first side panel 8, a central panel 9 and a second side panel 10.

Par « panneau », il faut comprendre une pièce plane en forme de couche, en carton en l'espèce, délimitée par une bordure comprenant des lignes de pliage, telles que des lignes rainées et/ou des lignes découpées.The term “panel” should be understood to mean a flat piece in the form of a layer, made of cardboard in this case, delimited by a border comprising fold lines, such as grooved lines and / or cut lines.

L'élément intercalaire 1 est de préférence tel que les deux panneaux de côté 8, 10 sont identiques l'un de l'autre.The intermediate element 1 is preferably such that the two side panels 8, 10 are identical to each other.

L'élément intercalaire 1 comprend également des lignes de pliage, telles que des lignes rainées de direction transversale T. Des lignes rainées sont bien connues dans le domaine de l'emballage et du carton et permettent de plier de façon relative deux panneaux adjacents en un emplacement prédéfini. De telles lignes rainées sont formées par mise en œuvre d'un outil de rainage. Il est entendu que l'expression « ligne rainée » doit être comprise de la façon la plus large comme signifiant que la ligne est apte et destinée au pliage relatif de deux panneaux adjacents.The spacer 1 also includes fold lines, such as transverse direction grooved lines T. Grooved lines are well known in the field of packaging and cardboard and allow two adjacent panels to be relatively folded into one. predefined location. Such creasing lines are formed by using a creasing tool. It is understood that the expression “grooved line” is to be understood in the widest sense as meaning that the line is suitable and intended for the relative folding of two adjacent panels.

Plus particulièrement, l'élément intercalaire 1 comprend deux lignes de pliage 11, 12 respectivement entre le panneau central 9 et les deux panneaux de côté 8, 10.More particularly, the intermediate element 1 comprises two fold lines 11, 12 respectively between the central panel 9 and the two side panels 8, 10.

Avantageusement, les deux lignes de pliage 11, 12 sont des lignes à découpage alterné. Par « à découpage alterné », il faut comprendre que sur la ligne, le carton est régulièrement et alternativement découpé de façon traversante puis non découpée, et ainsi de suite, de sorte à crée une ligne mixte.Advantageously, the two fold lines 11, 12 are alternating cutting lines. By "alternating cutting", it should be understood that on the line, the cardboard is regularly and alternately cut through and then not cut, and so on, so as to create a mixed line.

Les deux panneaux de côté 8, 10 sont ainsi articulés par rapport au panneau central 9 le long des lignes de pliage 11, 12, avantageusement parallèles l'une de l'autre. Ces deux lignes de pliage 11, 12 sont ainsi aptes et destinées au pliage relatif des panneaux de côté 8, 10 par rapport au panneau central 9 pour mettre en forme l'élément intercalaire 1. Une fois l'élément intercalaire mis en forme, les deux panneaux de côté 8, 10 forment avec le panneau central 9 un angle a, notamment obtus, par exemple de l'ordre de 120 degrés, comme illustré sur la figure 5.The two side panels 8, 10 are thus articulated relative to the central panel 9 along the fold lines 11, 12, advantageously parallel to one another. These two fold lines 11, 12 are thus suitable and intended for the relative folding of the side panels 8, 10 with respect to the central panel 9 in order to shape the intermediate element 1. Once the intermediate element has been shaped, the two side panels 8, 10 form with the central panel 9 an angle α, in particular obtuse, for example of the order of 120 degrees, as illustrated in figure 5 .

Le panneau central 9 comprend des premières ouvertures 13, avantageusement traversantes.The central panel 9 comprises first openings 13, advantageously through.

Chaque première ouverture 13 est apte et destinée à venir entourer la paroi latérale 3b d'un pot 2, en particulier au voisinage de sa paroi de fond 3a une fois le pack 20 constitué.Each first opening 13 is suitable and intended to surround the side wall 3b of a pot 2, in particular in the vicinity of its bottom wall 3a once the pack 20 has been formed.

Chaque première ouverture 13 a avantageusement une forme circulaire, ou plus généralement une forme correspondant à la forme de section d'une paroi latérale 3b de pot 2. Chaque première ouverture 13 est toutefois légèrement plus large que la paroi latérale 3b d'un pot 2, en particulier au voisinage de sa paroi de fond 3a, de sorte qu'un pot peut être disposé dans une première ouverture 13, tout en laissant un espace E entre l'élément intercalaire 1 et la paroi latérale 3b du pot 2 disposé dans la première ouverture 13, illustré sur la figure 5.Each first opening 13 advantageously has a circular shape, or more generally a shape corresponding to the cross-sectional shape of a side wall 3b of pot 2. Each first opening 13 is however slightly wider than the side wall 3b of a pot 2. , in particular in the vicinity of its bottom wall 3a, so that a pot can be arranged in a first opening 13, while leaving a space E between the intermediate element 1 and the side wall 3b of the pot 2 disposed in the first opening 13, shown on figure 5 .

Les panneaux de côté 8, 10 comprennent également des secondes ouvertures 14, avantageusement traversantes.The side panels 8, 10 also include second openings 14, advantageously through.

Chaque seconde ouverture 14 est apte et destinée à venir en contact, par exemple en butée, avec la fermeture de dessus 4 d'un pot 2, en particulier au voisinage de sa collerette 5 une fois le pack 20 constitué.Each second opening 14 is suitable and intended to come into contact, for example in abutment, with the top closure 4 of a pot 2, in particular in the vicinity of its collar 5 once the pack 20 has been formed.

A cet effet, chaque seconde ouverture 14 d'un panneau de côté 8, 10 est espacée du panneau central 9 par une distance D selon la direction longitudinale L. Plus particulièrement, chaque seconde ouverture 14 d'un panneau de côté 8, 10 est espacée d'une distance D de la ligne de pliage 11, 12 permettant l'articulation respective du panneau de côté 8, 10 par rapport au panneau central 9.For this purpose, each second opening 14 of a side panel 8, 10 is spaced from the central panel 9 by a distance D in the longitudinal direction L. More particularly, each second opening 14 of a side panel 8, 10 is spaced at a distance D from the fold line 11, 12 allowing the respective articulation of the side panel 8, 10 with respect to the central panel 9.

Chaque seconde ouverture 14 peut être délimitée par une première ligne découpée 15 et une seconde ligne découpée 16.Each second opening 14 can be delimited by a first cut line 15 and a second cut line 16.

La première ligne découpée 15 est rectiligne ou sensiblement rectiligne. La première ligne découpée 15 est plus particulièrement adaptée pour venir en contact, avantageusement sur sensiblement toute sa longueur, avec la fermeture 4 d'un pot 2. La seconde ligne découpée 16 est en arc de cercle. Alternativement, la seconde ligne découpée 16 peut prendre d'autres formes.The first cut line 15 is rectilinear or substantially rectilinear. The first cut line 15 is more particularly suitable for coming into contact, advantageously over substantially its entire length, with the closure 4 of a pot 2. The second cut line 16 is in an arc of a circle. Alternatively, the second cut line 16 can take other shapes.

L'élément intercalaire 1 est symétrique ou sensiblement symétrique par rotation axiale autour de la direction Z.The intermediate element 1 is symmetrical or substantially symmetrical by axial rotation around the Z direction.

Selon le mode de réalisation illustré sur les figures, l'élément intercalaire 1 comprend quatre premières ouvertures 13 et quatre second ouvertures 14.According to the embodiment illustrated in the figures, the intermediate element 1 comprises four first openings 13 and four second openings 14.

Les quatre première ouvertures 13 sont disposées deux à deux, face à face, sur le panneau central 9. Les secondes ouvertures 14 sont disposées sur les panneaux de côté 8, 10. Plus précisément, deux secondes ouvertures 14 sont disposés, avantageusement côte à côte selon la direction transversale T sur un panneau de côté 8, et deux autres secondes ouvertures 14 sont disposés, avantageusement côte à côte selon la direction transversale T sur l'autre panneau de côté 10.The four first openings 13 are arranged in pairs, face to face, on the central panel 9. The second openings 14 are arranged on the side panels 8, 10. More precisely, two second openings 14 are arranged, advantageously side by side. in the transverse direction T on a side panel 8, and two other second openings 14 are arranged, advantageously side by side in the transverse direction T on the other side panel 10.

L'élément intercalaire 1 est apte et destiné à réaliser, avec un flan 30, un conditionnement 40 d'un pack de pots 20, le pack 20 comprenant les pots 2 et le conditionnement 40.The intermediate element 1 is suitable and intended to produce, with a blank 30, a packaging 40 of a pack of jars 20, the pack 20 comprising the jars 2 and the packaging 40.

Un flan 30 en carton, à plat (les termes « en carton » et « à plat » devant être compris comme précédemment), est destiné à la réalisation du conditionnement 40.A cardboard blank 30, flat (the terms “cardboard” and “flat” to be understood as above), is intended for the production of packaging 40.

Le conditionnement 40 réalisé notamment par le flanc 30 est de type enveloppe tubulaire et il est réalisé par mise en volume et fermeture sur lui-même du flan 30, de sorte à épouser les pots 2 du pack 20 qui sont ainsi maintenus groupés.The packaging 40 produced in particular by the sidewall 30 is of the tubular envelope type and it is produced by setting up and closing on itself the blank 30, so as to match the jars 2 of the pack 20 which are thus kept grouped.

Par « enveloppe tubulaire », il faut comprendre que le conditionnement 40 a globalement six faces et s'inscrit dans une forme générale parallélépipédique, comporte quatre faces adjacentes fermées sur elles-mêmes et deux faces en vis-à-vis ouvertes.By "tubular envelope", it should be understood that the packaging 40 has six sides overall and is in a generally parallelepipedal shape, has four adjacent sides closed on themselves and two open facing sides.

Comme illustré sur la figure 2, le flan 30, à plat, est de forme générale rectangulaire. Le flan 30 comprend, disposés les uns à la suite des autres, un premier panneau de dessus 31a, un premier panneau latéral 32a, un panneau de dessous 33, un second panneau latéral 32b et un second panneau de dessus 31b (le terme « panneau » devant être compris comme précédemment).As shown on the figure 2 , the blank 30, lying flat, is generally rectangular in shape. The blank 30 comprises, arranged one after the other, a first top panel 31a, a first side panel 32a, a bottom panel 33, a second side panel 32b and a second top panel 31b (the term "panel" to be understood as above).

Le flan 30 est tel que les deux panneaux latéraux 32a et 32b ont les mêmes dimensions.The blank 30 is such that the two side panels 32a and 32b have the same dimensions.

Le premier panneau de dessus 31a est relativement large, destiné à former la totalité de la surface d'une paroi de dessus 34, alors que le second panneau de dessus 31b est relativement plus étroit, comme un volet, apte à venir au recto du premier panneau de dessus 31a. Une telle réalisation peut comprendre un moyen de solidarisation entre le premier panneau de dessus 31a et le second panneau de dessus 31b, tel que des pattes, des encoches ou une colle de solidarisation.The first top panel 31a is relatively wide, intended to form the entire surface of a top wall 34, while the second top panel 31b is relatively narrower, like a shutter, able to come to the front of the first. top panel 31a. Such an embodiment may comprise a means of securing between the first top panel 31a and the second top panel 31b, such as tabs, notches or a securing adhesive.

Le flan 30 comprend également des lignes de pliage, telles que des lignes rainées. Ces lignes sont aptes et destinées au pliage relatif des panneaux 31a, 32a, 33, 32b, 31b, à la mise en volume du flan 30, à la réalisation du conditionnement 40 et la constitution du pack 20.Blank 30 also includes fold lines, such as score lines. These lines are suitable and intended for the relative folding of the panels 31a, 32a, 33, 32b, 31b, for the volume setting of the blank 30, for the production of the packaging 40 and the constitution of the pack 20.

Plus précisément, le flan 30 comprend deux lignes rainées de dessous 35a, 35b entre le panneau de dessous 33 et les deux panneaux latéraux 32a, 32b, et deux lignes rainées de dessus 36a, 36b entre les deux panneaux de dessus 31a, 31b et les deux panneaux latéraux 32a, 32b.More precisely, the blank 30 comprises two grooved lines from below 35a, 35b between the bottom panel 33 and the two side panels 32a, 32b, and two grooved lines from above 36a, 36b between the two top panels 31a, 31b and the two side panels. two side panels 32a, 32b.

La mise en volume du flan 30 et la mise en forme de l'élément intercalaire 1 permet la réalisation du conditionnement 40 du pack 20.The shaping of the blank 30 and the shaping of the intermediate element 1 allows the packaging 40 of the pack 20 to be produced.

Le pack 20 comprend au moins deux couches de pots, une couche supérieure comprenant des pots de dessus 2b et une couche inférieure comprenant des pots de dessous 2a. La qualification de « pot de dessous 2a » vise ainsi à distinguer un tel pot d'un autre pot du pack 20, à savoir un « pot de dessus 2b » de la couche supérieure. Les pots de dessous 2a de la couche inférieure et les pots de dessus 2b de la couche supérieure sont avantageusement identiques les uns des autres.The pack 20 comprises at least two layers of pots, an upper layer comprising top pots 2b and a lower layer comprising bottom pots 2a. The qualification of “bottom pot 2a” thus aims to distinguish such a pot from another pot of the pack 20, namely a “top pot 2b” of the upper layer. The bottom pots 2a of the lower layer and the top pots 2b of the upper layer are advantageously identical to each other.

Toutefois, plus généralement, l'invention vise également tout pack 20 comprenant au moins deux couches de pots, ou plus. Le pack 20 peut comporter trois ou un plus grand nombre de couches de pots (non illustré), ayant alors plusieurs couches supérieures de pots et un ou plusieurs éléments intercalaires 1, en particulier pour chacune des couches supérieures du pack 20.However, more generally, the invention also relates to any pack 20 comprising at least two layers of pots, or more. The pack 20 may comprise three or a greater number of layers of pots (not shown), then having several upper layers of pots and one or more intermediate elements 1, in particular for each of the upper layers of the pack 20.

Selon le mode de réalisation illustré sur les figures, les couches inférieure et supérieure du pack 20 comprennent chacun quatre pots disposés deux à deux, face à face.According to the embodiment illustrated in the figures, the lower and upper layers of the pack 20 each comprise four pots arranged in pairs, face to face.

Toutefois, plus généralement, l'invention vise également un pack 20 dans lequel les couches de pots comprennent un nombre plus ou moins élevé de pots 2, ainsi qu'un agencement variable des pots dans une couche inférieure ou supérieure.However, more generally, the invention also relates to a pack 20 in which the layers of pots comprise a greater or lesser number of pots 2, as well as a variable arrangement of the pots in a lower or upper layer.

L'invention concerne également un procédé de réalisation du conditionnement 40 et de constitution du pack 20.The invention also relates to a method for producing the packaging 40 and for constituting the pack 20.

Pour ce procédé, on a à disposition un élément intercalaire 1 à plat, un flan à plat, des pots de dessous 2a et des pots de dessus 2b destinés à faire partie du pack 20.For this process, there is available a flat spacer 1, a flat blank, bottom pots 2a and top pots 2b intended to form part of the pack 20.

On dispose, successivement ou simultanément, les pots de dessous 2a en une couche inférieure sur le panneau de dessous 33 du flan 30. On dispose l'élément intercalaire 1 sur la couche inférieure de pots de dessous 2a, comme illustré sur la figure 3, et on dispose, successivement ou simultanément, les pots de dessus 2b en une couche supérieure sur la couche inférieure comme illustré sur la figure 4.The bottom pots 2a are arranged, successively or simultaneously, in a lower layer on the bottom panel 33 of the blank 30. The spacer element 1 is placed on the lower layer of bottom pots 2a, as illustrated in FIG. figure 3 , and we have, successively or simultaneously, the top pots 2b in an upper layer on the lower layer as illustrated on figure 4 .

Chaque pot de dessus 2b est avantageusement disposé à l'aplomb d'un pot de dessous 2a. Plus précisément, chaque pot de dessus 2b est centré sur un pot de dessous 2a.Each top pot 2b is advantageously placed directly above a bottom pot 2a. Specifically, each top pot 2b is centered on a bottom pot 2a.

Chaque pot de dessus 2b est également disposé dans une première ouverture 13 de l'élément intercalaire 1.Each top pot 2b is also disposed in a first opening 13 of the intermediate element 1.

On met en forme l'élément intercalaire 1, par pliage des deux panneaux de côté 8, 10, autour des deux lignes rainées 11, 12, par rapport au panneau central 9.The intermediate element 1 is shaped by folding the two side panels 8, 10, around the two grooved lines 11, 12, relative to the central panel 9.

Puis on met en volume le flan 30, autour des pots 2 du pack 20, par pliage des deux panneaux latéraux 32a, 32b, autour des deux lignes rainées de dessous 35a, 35b,Then the blank 30 is placed in volume, around the pots 2 of the pack 20, by folding the two side panels 32a, 32b, around the two grooved lines from below 35a, 35b,

Alternativement, la mise en forme de l'élément intercalaire 1 peut être réalisée lors de la mise en volume du flan 30, les panneaux latéraux 32a, 32b venant alors exercer un effort sur les panneaux de côté 8, 10 de l'élément intercalaire 1 afin d'entrainer le pliage des panneaux de côté 8, 10 par rapport au panneau central 9.Alternatively, the shaping of the intermediate element 1 can be carried out during the volume setting of the blank 30, the side panels 32a, 32b then exerting a force on the side panels 8, 10 of the intermediate element 1 in order to cause the folding of the side panels 8, 10 with respect to the central panel 9.

Lors de la mise en forme de l'élément intercalaire 1, les secondes ouvertures 14 viennent respectivement en butée avec les fermetures 4 d'un pot de dessous 2a, en particulier au voisinage de leurs collerettes 5. Plus particulièrement, une partie de la collerette 5 des pots de dessous 2a est insérée dans les secondes ouvertures 14, la première ligne découpée 15 venant alors en contact avec la fermeture 4 des pots de dessous 2a.During the shaping of the intermediate element 1, the second openings 14 respectively come into abutment with the closures 4 of a bottom pot 2a, in particular in the vicinity of their flanges 5. More particularly, part of the flange 5 of the bottom pots 2a is inserted into the second openings 14, the first cut line 15 then coming into contact with the closure 4 of the bottom pots 2a.

On finit également de mettre en volume le flan 30, autour des pots 2 du pack 20, par pliage des deux panneaux latéraux 32a, 32b autour des deux lignes rainées de dessus 36a, 36b.The blank 30 is also finished to form, around the pots 2 of the pack 20, by folding the two side panels 32a, 32b around the two top grooved lines 36a, 36b.

On dispose de façon coplanaire, par exemple l'un sur l'autre, et on solidarise l'un à l'autre, les deux panneaux de dessus 31a et 31b, de sorte à fermer sur lui-même le flan 1, à former la paroi de dessus 34, par mise en œuvre du moyen de solidarisation, et à réaliser le conditionnement 40 entourant les pots 2 du pack 20.The two top panels 31a and 31b are placed in a coplanar manner, for example one on top of the other, and the two top panels 31a and 31b are secured to one another, so as to close the blank 1 on itself, to form the top wall 34, by using the securing means, and to produce the packaging 40 surrounding the pots 2 of the pack 20.

Dans le pack 20 ainsi constitué et le conditionnement 40 ainsi réalisé, le flan 30 est alors disposé autour des pots 2. Plus précisément, les deux panneaux latéraux 32aa, 32bb sont érigés, vers le haut, par rapport au plan du panneau de dessous 33 et forment avec lui un angle, notamment obtus. Les panneaux latéraux 32a, 32b, s'étendent jusqu'à la paroi de dessus 34. La paroi de dessus 34 est disposée au-dessus et à l'aplomb du panneau de dessous 33.In the pack 20 thus formed and the packaging 40 thus produced, the blank 30 is then placed around the pots 2. More precisely, the two side panels 32aa, 32bb are erected, upwards, relative to the plane of the bottom panel 33 and form an angle with it, in particular obtuse. The side panels 32a, 32b extend as far as the top wall 34. The top wall 34 is disposed above and in line with the bottom panel 33.

Le flanc 30 permet de maintenir l'élément intercalaire 1 mis en forme, notamment du fait des panneaux latéraux 32a, 32b qui viennent exercer un effort sur les panneaux de côté 8, 10 de l'élément intercalaire 1.The sidewall 30 keeps the intermediate element 1 in shape, in particular due to the side panels 32a, 32b which exert a force on the side panels 8, 10 of the intermediate element 1.

Dans un tel pack 20, l'élément intercalaire 1 est disposé entre, et avantageusement parallèle à, le panneau de dessous 33 et la paroi de dessus 34.In such a pack 20, the intermediate element 1 is arranged between, and advantageously parallel to, the bottom panel 33 and the top wall 34.

Un tel pack 20 et un tel conditionnement 40 sont illustrés par la figure 5. La forme de détail du conditionnement 40 est adaptée à la forme de détail des pots 2. La description du conditionnement 40 qui vient d'être faite n'est donc pas exclusive d'autres formes, dans le cas de pots 2 de formes différentes.Such a pack 20 and such a packaging 40 are illustrated by figure 5 . The detail shape of the packaging 40 is adapted to the detail shape of the jars 2. The description of the package 40 which has just been given is therefore not exclusive of other shapes, in the case of jars 2 of different shapes.

Dans le cas d'un pack 20 ayant plus de deux couches de pots, le conditionnement 40 est, dans son ensemble, analogue à celui d'un pack 20 à deux couches de pots, si ce n'est, tout d'abord, que sa dimension est plus grande de sorte à être adaptée au nombre de couches. L'élément intercalaire 1 est adapté pour que chaque première ouverture 13 soit disposée autour d'un pot de dessus 2b de la couche supérieure. En outre, l'élément intercalaire 1 est adapté pour que chaque seconde ouverture 14 soit en contact, avantageusement en butée, avec un pot de dessous 2a de la couche inférieure.In the case of a pack 20 having more than two layers of pots, the packaging 40 is, on the whole, similar to that of a pack 20 with two layers of pots, except, first of all, that its dimension is larger so as to be adapted to the number of layers. The intermediate element 1 is adapted so that each first opening 13 is arranged around a top pot 2b of the upper layer. In addition, the intermediate element 1 is adapted so that each second opening 14 is in contact, advantageously in abutment, with a bottom pot 2a of the lower layer.

Les pots de dessus 2b sont respectivement disposés dans les premières ouvertures 13 de l'élément intercalaire 1, de sorte à assurer l'espacement et le calage de ces pots de dessus 2b au voisinage de leurs parois de fond 3a. Les premières ouvertures 13 sont ainsi destinées à arrêter les pots de dessus 2b sur leurs parois latérales 3b, au voisinage de leurs parois de fond 3a.The top pots 2b are respectively arranged in the first openings 13 of the intermediate element 1, so as to ensure the spacing and the wedging of these top pots 2b in the vicinity of their bottom walls 3a. The first openings 13 are thus intended to stop the top pots 2b on their side walls 3b, in the vicinity of their bottom walls 3a.

Par « arrêter les pots de dessus 2b sur leurs parois latérales 3b », il faut comprendre que, dans le pack 20, les pots de dessus 2b sont empêchés, au moins dans une certaine mesure, de se déplacer de façon relative (de façon intempestive) par rapport au conditionnement 40 et/ou aux pots de dessous 2a, ou de se choquer les uns les autres, car le déplacement de la paroi latérale 3b de chaque pot de dessus 2b est adjacente à une première ouverture 13, notamment espacé d'un espace E limité. Les pots de dessus 2b sont ainsi maintenus dans toutes les directions, notamment dans la direction longitudinale L et la direction transversale T de l'élément intercalaire 1.By "stopping the top pots 2b on their side walls 3b" it should be understood that, in pack 20, the top pots 2b are prevented, at least to some extent, from moving relatively (inadvertently ) relative to the packaging 40 and / or the bottom pots 2a, or to collide with each other, because the displacement of the side wall 3b of each top pot 2b is adjacent to a first opening 13, in particular spaced apart from a limited space E. The top pots 2b are thus maintained in all directions, in particular in the longitudinal direction L and the transverse direction T of the intermediate element 1.

Par arrêter les pots de dessus 2b sur leurs parois latérales 3b « au voisinage de leurs parois de fond 3a », il faut comprendre que l'élément intercalaire 1, et notamment les premières ouvertures 13, sont écartées de la paroi de fond 3a des pots de dessus 2b d'un écartement H.By stopping the top pots 2b on their side walls 3b "in the vicinity of their bottom walls 3a", it should be understood that the intermediate element 1, and in particular the first openings 13, are spaced from the bottom wall 3a of the pots. from above 2b with a distance H.

Plus précisément, du fait notamment de la distance D séparant les secondes ouvertures 14 du panneau central 9, l'élément intercalaire 1 est apte et destiné à permettre l'écartement H entre le panneau central 10 et la paroi de fond 3a des pots de dessus 2b ou la fermeture 4 des pots de dessous 2a (puisque les pots de dessus 2b reposent par leurs parois de fond 3a sur les fermetures 4 des pots de dessous 2a).More precisely, due in particular to the distance D separating the second openings 14 from the central panel 9, the intermediate element 1 is suitable and intended to allow the spacing H between the central panel 10 and the bottom wall 3a of the top pots. 2b or the closure 4 of the bottom pots 2a (since the top pots 2b rest by their bottom walls 3a on the closures 4 of the bottom pots 2a).

Du fait de cet écartement H, il est possible de maintenir de façon satisfaisante les pots de dessus dans le pack 20. En effet, en l'absence d'écartement, les pots de dessus 2b pourraient sinon facilement sortir des premières ouvertures 13 lors d'un déplacement brusque du pack 20.Due to this spacing H, it is possible to maintain the top pots satisfactorily in the pack 20. In fact, in the absence of spacing, the top pots 2b could otherwise easily come out of the first openings 13 during '' a sudden displacement of the 20 pack.

L'écartement H est relativement faible au regard de la distance entre la paroi de fond 3a et la fermeture de dessus 5 d'un pot 2. L'écartement H est de plus de 0,5 centimètres, voire de plus de un centimètre, voire de plus de deux centimètres. Cette réalisation n'étant toutefois pas limitative, l'écartement H pouvant être plus petit ou plus grand.The distance H is relatively small compared to the distance between the bottom wall 3a and the top closure 5 of a pot 2. The distance H is more than 0.5 centimeters, or even more than one centimeter, or even more than two centimeters. However, this embodiment is not limiting, the spacing H being able to be smaller or larger.

Les premières ouvertures 13 étant propres à arrêter les pots de dessus 2b, comme il vient d'être exposé, ils participent à ce que, dans le pack 20, les pots de dessus 2b ne puissent pas, ou ne puissent que peu, se déplacer de façon intempestive ou se choquer les uns les autres.The first openings 13 being suitable for stopping the top pots 2b, as has just been explained, they take part in the fact that, in the pack 20, the top pots 2b cannot, or can only slightly, move. untimely or shocking each other.

Le pack 20 peut en outre comporter des fentes ou découpes 21, 22 pour laisser saillir la collerette 5 des pots de dessus 2b ou encore la paroi de fond 3a des pots de dessous 2a vers l'extérieur du pack 20.The pack 20 can also include slits or cutouts 21, 22 to let the collar 5 of the top pots 2b protrude or the bottom wall 3a of the bottom pots 2a to the outside of the pack 20.

Bien évidemment, l'invention n'est pas limitée aux modes de réalisation décrits précédemment et fournis uniquement à titre d'exemple. Elle englobe diverses modifications, formes alternatives et autres variantes que pourra envisager l'homme du métier dans le cadre de la présente invention et notamment toutes combinaisons des différents modes de fonctionnement décrits précédemment, pouvant être pris séparément ou en association, sans sortir toutefois du cadre défini par les revendications.Obviously, the invention is not limited to the embodiments described above and provided solely by way of example. It encompasses various modifications, alternative forms and other variants which a person skilled in the art may envisage in the context of the present invention and in particular any combination of the various operating modes described above, which may be taken separately or in combination, without however departing from the scope. defined by the claims.
