Description

L'invention concerne une boîte de conditionnement, modulable notamment pour objets fragiles ainsi que son procédé de fabrication.The invention relates to a packaging box, adjustable in particular for fragile objects and its manufacturing process.

Elle vise plus spécifiquement une boîte de conditionnement du type telle que notamment décrite dans le brevet EP 0 557 804 comportant, en premier lieu, deux moitiés de boîte, dites respectivement couvercle et fond, formées chacune d'une paroi frontale sur le pourtour de laquelle s'étend un rebord périphérique de jonction desdits fond et couvercle, doté de logements d'insertion et de blocage de pièces de liaison externes dont au moins un nombre prédéterminé de pièces de liaison dotées d'organes de fermeture de la boîte de conditionnement.It is more specifically a packaging box of the type such as in particular described in the patent EP 0 557 804 having, in the first place, two box halves, respectively said cover and bottom, each formed of a front wall on the periphery of which extends a peripheral rim of junction of said bottom and cover, provided with insertion housings and blocking external connecting pieces including at least a predetermined number of connecting pieces provided with closure members of the packaging box.

Le couvercle et le fond de cette boîte de conditionnement intègrent, en outre, en vue de la protection des objets, soit un coussin, soit un film maintenu tendu au moyen d'un jonc, par coincement de sa périphérie dans une rainure interne s'étendant sur la totalité du contour du rebord périphérique desdits couvercle et fond.The lid and the bottom of this packaging box also incorporate, for the purpose of protecting the objects, either a cushion or a film held taut by means of a rod, by wedging its periphery in an internal groove. extending over the entire contour of the peripheral rim of said cover and bottom.

Selon ce principe, lors de la fermeture de la boîte de conditionnement, les deux plaques de mousse ou les deux films sont déformés par l'objet inséré entre ces deux protections, et exercent sur le couvercle et le fond de la boîte de conditionnement des pressions locales d'intensités variables tendant à provoquer l'ouverture de cette dernière.According to this principle, when closing the conditioning box, the two foam plates or the two films are deformed by the object inserted between these two protections, and exert on the lid and the bottom of the pressure conditioning box. localities of variable intensities tending to cause the opening of the latter.

Les pressions locales exercées sur le fond et le couvercle étant fonctions de la forme (dimensions, épaisseurs...) et du volume de l'objet conditionné, la solution idéale consiste à adapter le nombre et la position des organes de fermeture de la boîte de conditionnement en fonction des caractéristiques dimensionnelles de l'objet à conditionner.The local pressures exerted on the bottom and the cover being functions of the shape (dimensions, thicknesses ...) and the volume of the conditioned object, the ideal solution consists in adapting the number and the position of the closing elements of the box conditioning according to the dimensional characteristics of the object to be packaged.

Concernant la boîte de conditionnement décrite dans le brevet EP 0 557 804 , cette solution conduit à multiplier le nombre de logements (fentes 5 décrites dans ce document) destinés à loger les pièces de liaison entre le fond et le couvercle.Concerning the packaging box described in the patent EP 0 557 804 this solution leads to multiply the number of housings (slots 5 described in this document) intended to house the connecting pieces between the bottom and the cover.

Toutefois, la multiplication de ces logements conduit à complexifier la forme des boîtes de conditionnement et donc les moules et le coût de production de ces dernières.However, the multiplication of these homes leads to complexity of the shape of the packaging boxes and thus the molds and the cost of production of the latter.

De plus, la réalisation de chacun de ces logements impose de réaliser un bossage tant à l'extérieur qu'à l'intérieur de la boîte de conditionnement, de sorte que la multiplication de ces logements conduit, de façon significative, à augmenter les dimensions externes et à diminuer le volume interne utile desdites boîtes de conditionnement.In addition, the realization of each of these dwellings requires a boss to be made both outside and inside the packaging box, so that the multiplication of these dwellings leads significantly to increase the dimensions. external and to reduce the useful internal volume of said conditioning boxes.

Pour ces raisons, la pratique actuelle consiste à réaliser une pluralité de modèles différents de boîtes de conditionnement, chacun adapté à une enveloppe donnée de répartition des pressions exercées sur le fond et le couvercle. Toutefois, cette solution impose de multiplier le nombre de moules de fabrication des boîtes de conditionnement, avec pour conséquence une augmentation du coût de production. De plus, elle conduit également à complexifier la gestion des stocks de boîtes de conditionnement.For these reasons, the current practice consists in producing a plurality of different models of packaging boxes, each adapted to a given envelope of distribution of the pressures exerted on the bottom and the lid. However, this solution requires to multiply the number of manufacturing molds packaging boxes, resulting in an increase in the cost of production. In addition, it also leads to complicating the management of packaging box stocks.

Les boîtes B de conditionnement représentées à titre d'exemple aux figures 1 et 2 sont composées de deux moitiés 1, 1a de boîte identiques, dites couvercle 1 et fond 1a, formées chacune d'une paroi frontale de forme rectangulaire, sur le pourtour de laquelle s'étend un rebord périphérique formé de plusieurs éléments de jonction 2, 3, 4 de différents types desdits fond et couvercle formant les moitiés 1, 1a de boîte visibles à la figure 2.Packaging boxes B represented by way of example to Figures 1 and 2 are composed of two identical box halves 1, 1a, so-called lid 1 and bottom 1a, each formed of a rectangular front wall, on the periphery of which extends a peripheral rim formed of a plurality of connecting elements 2, 3 , 4 different types of said bottom and lid forming the halves 1, 1a box visible to the figure 2 .

Il existe donc une première série d'éléments de jonction 2 à 4 associés au fond 1a de la boîte B, une seconde série d'éléments de jonction 2 à 4 étant superposée à la première série en étant associée au couvercle 1 de la boîte B, les éléments de jonction d'une série étant inversées par rapport aux éléments de jonction de l'autre série.There is therefore a first series of junction elements 2 to 4 associated with the bottom 1a of the box B, a second series of junction elements 2 to 4 being superimposed on the first series being associated with the lid 1 of the box B the joining elements of one series being reversed with respect to the joining elements of the other series.

Les éléments de jonction 2 4 présentent chacune une nervure faisant saillie vers l'extérieur des moitiés 1 et 1a de la boîte, l'ensemble des nervures des éléments de jonction 2, 4 formant une nervure continue et de même dimension sur toute la périphérie de la boîte B. Ceci est valable pour la première série d'éléments de jonction 2 à 4 comme pour la seconde série, les nervures formées par les deux séries formant une nervure commune 14.The connecting elements 2 4 each have a rib projecting outwards from the halves 1 and 1a of the box, the set of ribs of the connecting elements 2, 4 forming a continuous rib of the same size over the entire periphery of the box. the box B. This is valid for the first series of junction elements 2 to 4 as for the second series, the ribs formed by the two series forming a common rib 14.

Les éléments de jonction 2 à 4 de la première série associée au fond 1a portent la nervure à leur portion opposée à celle solidarisée au fond 1a, tandis que les éléments de jonction 2 à 4 de la seconde série associée au couvercle 1 portent la nervure à leur portion opposée à celle solidarisée au couvercle 1. Il s'ensuit que la nervure commune 14 se trouve à mi-hauteur sur le pourtour de la boîte B de conditionnement.The joining elements 2 to 4 of the first series associated with the bottom 1a bear the rib at their portion opposite to that secured to the bottom 1a, while the connecting elements 2 to 4 of the second series associated with the cover 1 carry the rib to their opposite portion to that secured to the lid 1. It As a result, the common rib 14 is at mid-height on the periphery of the packaging box B.

La liaison du fond 1a et du couvercle 1 s'effectue entre la première série et la seconde série d'éléments de jonction 2 à 4 et est réalisée au moyen de deux types de pièces de liaison, dites pièces charnières 5 et pièces verrous 6.The connection of the bottom 1a and the cover 1 is made between the first series and the second series of connecting elements 2 to 4 and is made by means of two types of connecting pieces, called hinge parts 5 and lock parts 6.

En premier lieu, les pièces charnières 5 sont adaptées pour être positionnées le long d'un des bords longitudinaux de chacune des moitiés de boîte, le bord longitudinal d'une moitié de boîte B étant adjacent au bord longitudinal de l'autre moitié de boîte B de façon à permettre l'articulation du fond 1a et du couvercle 1. Avantageusement, ces pièces charnières 5 entourent la largeur de la nervure commune 14 formée par les nervures des première et secondes séries d'éléments de jonction 2 à 4.Firstly, the hinge pieces 5 are adapted to be positioned along one of the longitudinal edges of each of the box halves, the longitudinal edge of one box half B being adjacent to the longitudinal edge of the other box half. B so as to allow the articulation of the bottom 1a and the cover 1. Advantageously, these hinge parts 5 surround the width of the common rib 14 formed by the ribs of the first and second series of connecting elements 2 to 4.

La boîte B comporte aussi des pièces verrous 6. Il peut être prévu des pièces verrous longitudinales 6 disposées sur un bord longitudinal de la boîte B sur les extrémités adjacentes de deux éléments de jonction 2 ou 3, 3 ou 4, 2 ou 4 ainsi que des pièces verrous latérales 6 disposées sur un bord latéral de la boîte B sur les extrémités adjacentes de deux éléments de jonction 2 ou 3, 3 ou 4, 2 ou 4. L'élément de jonction 2 est dit élément de jonction formant angle, cet élément 2 étant composé de deux parties s'étendant sensiblement perpendiculairement. Avantageusement, ces pièces charnières 6 entourent la largeur de la nervure commune 14 formée par les nervures des première et secondes séries d'éléments de jonction 2 à 4.Box B also includes lock pieces 6. Longitudinal lock pieces 6 may be provided on a longitudinal edge of box B on the adjacent ends of two joining elements 2 or 3, 3 or 4, 2 or 4, and lateral lock pieces 6 arranged on a lateral edge of the box B on the adjacent ends of two joining elements 2 or 3, 3 or 4, 2 or 4. The joining element 2 is called an angle joining element, this element 2 being composed of two parts extending substantially perpendicularly. Advantageously, these hinge parts 6 surround the width of the common rib 14 formed by the ribs of the first and second series of junction elements 2 to 4.

Les pièces charnières 5 et verrous 6 sont avantageusement sous la forme d'étriers avec une partie supérieure recourbée vers l'intérieur de la boîte B, ladite partie supérieure recouvrant une portion correspondante de la nervure commune 4 formée par la succession des éléments de jonction 2, 3, 4 de chaque série et de la superposition des deux séries d'éléments de jonction 2 à 4.The hinge parts 5 and locks 6 are advantageously in the form of stirrups with an upper part curved towards the inside of the box B, said upper part covering a corresponding portion of the common rib 4 formed by the succession of the connecting elements 2 , 3, 4 of each series and the superimposition of the two sets of connecting elements 2 to 4.

Des pièces verrous 6 latérales et charnières 5 longitudinales 6 sont également prévues entre certains des éléments de jonction adjacents avec une répartition uniforme sur un bord longitudinal latéral. Ces pièces permettent de maintenir deux éléments de jonction superposés. Avantageusement elles peuvent être placées sur les extrémités en vis-à-vis de deux éléments de jonction adjacents de la première série sur lesquels sont superposés deux éléments de jonction adjacents de la seconde série en ayant ainsi une action sur les quatre éléments de jonction.To the figure 3 the circular joining element 11 is extended by substantially rectilinear joining elements 3 and 4 alternating which join two circular joining elements 11 forming the longitudinal and lateral edges of the box B of substantially rectangular shape. Lateral latches 6 and longitudinal hinges 6 are also provided between some of the adjacent junctures with uniform distribution on a lateral longitudinal edge. These parts make it possible to maintain two superposed connecting elements. Advantageously they can be placed on the ends opposite two adjacent junction elements of the first series on which two adjacent junction elements of the second series are superimposed, thus having an effect on the four junction elements.

Dans une autre forme de réalisation d'une boîte selon la présente invention montrée à la figure 4, la boîte Bc est circulaire et son rebord périphérique est entièrement formé par des éléments de jonction circulaires 11, au nombre de quatre à cette figure.In another embodiment of a box according to the present invention shown in FIG. figure 4 , the box Bc is circular and its peripheral rim is entirely formed by circular joining elements 11, four in number in this figure.

As previously indicated for the circular joining element 11, the corner joining element 2 has an external groove 16 and an internal groove 15 at one end of the rib 14 bordering it and arranged towards its lower end. Similarly, the upper end 13 of the corner junction element 2 is bent at right angles, forming a bearing portion intended to rest on the upper face of the lid.

Aux figures 7 et 8, il est monté respectivement un élément de jonction 3, 4 rectiligne, l'élément de jonction 4 de la figure 7 étant symétrique par rapport à l'élément de jonction 3 de la figure 8. Ces éléments de jonction 3, 4 servent avantageusement à former le bord latéral ou longitudinal d'une boîte de conditionnement, ces éléments de jonction 3, 4 étant disposés en alternance sur ledit bord.To the Figures 7 and 8 it is mounted respectively a connecting element 3, 4 rectilinear, the connecting element 4 of the figure 7 being symmetrical with respect to the connecting element 3 of the figure 8 . These joining elements 3, 4 advantageously serve to form the lateral or longitudinal edge of a packaging box, these joining elements 3, 4 being arranged alternately on said edge.

Comme précédemment indiqué pour l'élément de jonction circulaire 11 et l'élément de jonction formant angle 2, les éléments de jonction rectilignes 3, 4 présentent une rainure externe 16 et une rainure interne 15 à une extrémité de la nervure 14 les bordant et disposées vers leur extrémité inférieure. De même, l'extrémité supérieure des éléments de jonction rectilignes 3, 4 est recourbée à angle droit en formant une partie d'appui 13 destinée à reposer sur la face supérieure du couvercle.As previously indicated for the circular joining element 11 and the corner joining element 2, the rectilinear joining elements 3, 4 have an external groove 16 and an internal groove 15 at one end of the rib 14 bordering them and arranged towards their lower end. Similarly, the upper end of the rectilinear junction elements 3, 4 is bent at right angles, forming a bearing portion 13 intended to rest on the upper face of the cover.

En se référant à l'ensemble des figures 5 à 8, il peut être vu que chaque élément de jonction 2 à 4, 11 porte à sa partie d'appui sur sa face orientée vers le couvercle ou le fond, une partie en saillie de forme pyramidale 9 s'étendant au moins partiellement dans la longueur dudit élément 2 à 4, 11. Cette partie en saillie pyramidale 9 et son rôle seront plus amplement décrits en regard des figures 13 et 14.Referring to all Figures 5 to 8 , it can be seen that each connecting element 2 to 4, 11 carries at its supporting part on its face facing the lid or the bottom, a projecting portion of pyramidal shape 9 extending at least partially in the length of said element 2 to 4, 11. This pyramidal projection portion 9 and its role will be more fully described with respect to figures 13 and 14 .

En se référant à nouveau à la figure 1, il peut être vu que la série d'éléments de jonction 2 à 4 formant un bord de la boîte en mettant à part les éléments de jonction d'angle 2 est composée d'une suite alternée d'éléments 3 et d'éléments 4 qui sont symétriques.Referring again to the figure 1 it can be seen that the series of joining elements 2 to 4 forming an edge of the box apart from the corner joining elements 2 is composed of an alternating sequence of elements 3 and 4 which are symmetrical.

De même dans les première et seconde séries superposées, un élément de jonction 3 est superposé à un élément de jonction 4 qui lui est symétrique, ces éléments étant alors en position verticale inversée.Similarly in the first and second superimposed series, a junction element 3 is superimposed on a junction element 4 which is symmetrical thereto, these elements then being in an inverted vertical position.

Il peut être vu notamment à la figure 1 que les parties d'appui 13 des éléments de jonction 2, 3, 4 sont dans le prolongement les unes des autres quand les éléments de jonction 2, 3, 4 appartiennent à un même bord et à une même série.It can be seen especially at the figure 1 that the support portions 13 of the connecting elements 2, 3, 4 are in the extension of each other when the connecting elements 2, 3, 4 belong to the same edge and to the same series.

En se référant aux figures 9 à 12, il peut être vu que les éléments de jonction 3, 4 présentent une rainure interne 15 s'étendant avantageusement sur la totalité du contour dudit rebord périphérique.Referring to Figures 9 to 12 it can be seen that the connecting elements 3, 4 have an internal groove 15 extending advantageously over the entire contour of said peripheral flange.

De façon usuelle, cette rainure interne 15 est utilisée pour maintenir tendu le film 7 obturant la face ouverte de chaque moitié 1, 1a de la boîte, ceci par coincement de la périphérie de ce film 7 dans ladite rainure interne 15, au moyen d'un jonc 8 logé dans cette dernière.In the usual manner, this internal groove 15 is used to keep the film 7 closing the open face of each half 1, 1a of the box taut, this by jamming the periphery of this film 7 in said internal groove 15, by means of a rod 8 housed in the latter.

De plus, la rainure interne 15 d'une des moitiés 1, 1a de boîte loge partiellement un joint d'étanchéité en l'exemple de forme générale oblongue, adapté pour assurer l'étanchéité des boîtes de conditionnement. Le joint d'étanchéité est réalisé en matériau souple, par exemple un élastomère et repose sur le jonc 8 d'une moitié 1, 1 a de boîte. Le joint d'étanchéité adopte de préférence une section oblongue.In addition, the internal groove 15 of one of the halves 1, 1a box partially houses a seal in the example of generally oblong shape, adapted to seal the conditioning boxes. The seal is made of flexible material, for example an elastomer and rests on the ring 8 of a half 1, 1 a box. The seal preferably adopts an oblong section.

La dimension de la section oblongue du joint est de préférence réalisée de telle sorte que les deux tiers de la longueur de cette section sont par exemple introduits en force dans la rainure interne 15 d'une moitié 1, 1a de boîte en butée sur le jonc 8 et qu'un tiers de cette section dépasse de la rainure interne 15 de façon à pénétrer dans la rainure interne 15 de l'autre moitié de boîte 1 lors de la fermeture et faire étanchéité avec celle-ci.The dimension of the elongated section of the seal is preferably made so that two-thirds of the length of this section are for example forced into the internal groove 15 of a half 1, 1a of box abutting on the rod 8 and a third of this section protrudes from the internal groove 15 so as to penetrate into the internal groove 15 of the other half of box 1 when closing and seal with it.

Il est à noter que le joint d'étanchéité peut être présent seul dans la ou les rainures internes 15, sans les joncs 8 si le film 7 est inutilisé, par exemple. Dans ce cas, le joint et/ou la rainure interne 15 sont appariés de telle sorte que le joint soit logé en butée dans le fond de la rainure interne 15 d'une moitié 1, 1a de boîte en sorte de dépasser de celle-ci de manière suffisante pour pénétrer dans la rainure interne 15 de l'autre moitié de boîte et faire étanchéité avec celle-ci.It should be noted that the seal may be present alone in the internal groove or grooves 15, without the rods 8 if the film 7 is unused, for example. In this case, the seal and / or the internal groove 15 are matched such that the seal is housed in abutment in the bottom of the inner groove 15 of a half 1, 1a of box so as to exceed it sufficiently to penetrate and seal the inner groove 15 of the other can half.

Les éléments de jonction 3 et 4 présentent également une rainure externe périphérique 16 ménagée dans la paroi frontale de façon à s'étendre sur le pourtour de ladite paroi frontale. De plus, cette rainure externe 16 et la rainure interne 15 sont axées par rapport à un même plan de symétrie.The joining elements 3 and 4 also have a peripheral external groove 16 formed in the front wall so as to extend around the periphery of said front wall. In addition, this outer groove 16 and the inner groove 15 are oriented relative to the same plane of symmetry.

En l'exemple représenté, cette rainure externe 16 peut dans chacune des séries d'éléments de jonction s'étendre de façon continue sur l'intégralité du pourtour de la boîte. Toutefois, elle peut également, dans le cadre de l'invention, être interrompue dans les angles de la boîte.In the example shown, this outer groove 16 can in each series of connecting elements extend continuously over the entire periphery of the box. However, it may also, in the context of the invention, be interrupted in the corners of the box.

Cette rainure externe 16 peut également consister, dans le cadre de l'invention, en une rainure discontinue composée de tronçons séparés présentant chacun une longueur conjuguée de la longueur des pièces de liaison décrites ci-dessous.This external groove 16 may also consist, in the context of the invention, in a discontinuous groove composed of separate sections each having a combined length of the length of the connecting pieces described below.

Comme précédemment mentionné, il est avantageusement prévu des pièces charnières 5 et des pièces verrous 6, consistant en des étriers 21 adaptés pour coiffer le bord périphérique de la boîte de conditionnement dans la position fermée de cette dernière, lesdits étriers 21 étant prolongés d'organes de liaison 19b, 19c de formes adaptées pour s'insérer dans les rainures externes 16 ménagées dans les parois desdits éléments de jonction 3, 4.As previously mentioned, it is advantageously provided hinge parts 5 and lock pieces 6, consisting of stirrups 21 adapted to cap the peripheral edge of the conditioning box in the closed position thereof, said stirrups 21 being extended by organs link 19b, 19c of shapes adapted to fit into the external grooves 16 formed in the walls of said connecting elements 3, 4.

En premier lieu, les pièces charnières 5 sont adaptées pour être positionnées le long d'un des bords longitudinaux des moitiés de boîte 1, 1a, de façon à permettre l'articulation du fond 1a et du couvercle 1.First, the hinge parts 5 are adapted to be positioned along one of the longitudinal edges of the box halves 1, 1a, so as to allow the articulation of the bottom 1a and the lid 1.

Les figures 11 et 12 montrent une pièce charnière en position fermée et ouverte.The figures 11 and 12 show a hinge piece in the closed and open position.

Chacune de ces pièces charnières 5 comporte un étrier 21 formé de deux branches articulées autour d'un pivot 22 constitué d'une zone centrale de moindre épaisseur. A la figure 11, les deux branches de l'étrier 21 sont dans le prolongement l'une de l'autre tandis qu'à la figure 11, les deux branches de l'étrier 21 sont repliées l'une contre l'autre par pivotement d'une des branches par rapport au pivot 22.Each of these hinge parts 5 comprises a stirrup 21 formed of two branches articulated around a pivot 22 consisting of a central area of lesser thickness. To the figure 11 , the two branches of the stirrup 21 are in the extension of each other while at the figure 11 , the two branches of the stirrup 21 are folded against one another by pivoting one of the branches relative to the pivot 22.

En se référant particulièrement à la figure 12, chaque branche de l'étrier 21 est prolongée d'un élément de liaison 19a, 19b présentant la forme d'un L disposé de façon définir une forme de U avec ladite branche. L'élément de liaison 19a, 19b est composé, à cet effet, d'une aile 19a orthogonale à cette branche et d'une aile 19b, dite d'encastrement, parallèle à cette branche et de section adaptée pour s'insérer dans la rainure externe 16.With particular reference to figure 12 each branch of the stirrup 21 is extended by a link member 19a, 19b having the shape of an L disposed to define a U-shape with said branch. The connecting element 19a, 19b is composed, for this purpose, of a wing 19a orthogonal to this branch and a wing 19b, said embedding, parallel to this branch and section adapted to fit into the external groove 16.

De plus, chaque branche de l'étrier 21 peut comporter, au niveau de son extrémité jouxtant l'élément de liaison 19a, 19b, une gorge transversale 20 délimitée par une aile 19a et la branche de l'étrier 21 associé. Cette gorge transversale 20 reçoit un ergot 20a respectif porté par la partie de la nervure 14 appartenant à un élément de jonction 3, 4.In addition, each branch of the stirrup 21 may comprise, at its end adjacent to the connecting element 19a, 19b, a transverse groove 20 delimited by a wing 19a and the branch of the stirrup 21 associated. This transverse groove 20 receives a respective lug 20a carried by the portion of the rib 14 belonging to a connecting element 3, 4.

Tel que notamment représenté à la figure 12, la mise en place des pièces charnières 5 est réalisée en présentant chaque pièce charnière 5, dans la position repliée de sa charnière, en regard des parois frontales, positionnées côte à côte, des deux moitiés de boîte 1, 1a, puis en enfonçant les deux ailes d'encastrement 19b dans les rainures externes 16 desdites parois frontales, jusqu'à obtenir l'encliquetage de l'ergot 20a dans sa gorge 20 associée.As represented in particular in figure 12 , the positioning of the hinge parts 5 is carried out by presenting each hinge part 5, in the folded position of its hinge, facing the front walls, positioned side by side, of the two box halves 1, 1a, and then pushing in the two flanges 19b in the outer grooves 16 of said end walls, until the latch 20a snap into its groove 20 associated.

Chacune des pièces verrous 6 peut comporter également un étrier 21 présentant une âme formée de deux branches articulées autour d'un pivot 22 constitué d'une zone centrale de moindre épaisseur.Each of the lock pieces 6 may also comprise a stirrup 21 having a core formed of two branches articulated around a pivot 22 consisting of a central zone of lesser thickness.

De plus, une de ces branches est prolongée d'un élément de liaison 19b identique aux éléments de liaison ci-dessus décrits des pièces charnières 5, présentant donc la forme d'un L disposé de façon définir une forme de U avec ladite branche.In addition, one of these branches is extended by a connecting element 19b identical to the connecting elements described above hinge parts 5, thus having the shape of an L disposed to define a U-shape with said branch.

L'autre branche est, quant à elle, prolongée par un élément de verrouillage 19c articulé, par rapport à ladite branche, autour d'un pivot 23 constitué d'une zone de jonction de moindre épaisseur. Cet élément de verrouillage 19c comporte, en premier lieu, un crochet de verrouillage s'étendant, de façon naturelle, sensiblement orthogonalement par rapport à ladite branche, et doté, au niveau de son extrémité libre, d'un organe de verrouillage 24 en forme de bourrelet de forme adaptée pour se bloquer dans la rainure externe 16 en vis-à-vis.The other branch is, in turn, extended by a locking member 19c articulated, relative to said branch, about a pivot 23 consisting of a junction zone of lesser thickness. This element of 19c lock comprises, in the first place, a locking hook extending, naturally, substantially orthogonal to said branch, and having, at its free end, a locking member 24 in the form of a bead of shape adapted to lock in the outer groove 16 vis-à-vis.

De plus, l'élément de verrouillage 19c est associé à une languette 25 orthogonale audit élément de verrouillage 19c, formant un levier à actionnement manuel de manoeuvre dudit élément.In addition, the locking member 19c is associated with a tongue 25 orthogonal to said locking member 19c, forming a manually operated lever for operating said member.

Entre portions adjacentes de l'élément de verrouillage 19c et de la languette 25 prévue une rainure 26a faisant office de levier d'actionnement dudit élément de verrouillage 19c.Between adjacent portions of the locking member 19c and the tongue 25 there is provided a groove 26a acting as a lever for actuating said locking member 19c.

Tel que notamment représenté à la figure 10, cette rainure 26a est adaptée pour loger, lors de l'empilage de boîtes de conditionnement selon l'invention, un talon externe 26b délimité par une rainure, positionné extérieurement au niveau de la base de l'étrier 21.As represented in particular in figure 10 , this groove 26a is adapted to accommodate, during the stacking of packaging boxes according to the invention, an outer bead 26b delimited by a groove, positioned externally at the base of the stirrup 21.

De façon similaire aux pièces charnières 5, la mise en place de ces pièces verrous 6 est réalisée en présentant chacune desdites pièces verrous, dans la position repliée de leur charnière, en regard d'une paroi frontale, puis en enfonçant l'aile d'encastrement 19b dans la rainure externe 16 de ladite paroi frontale, jusqu'à obtenir l'encliquetage de la nervure dans la gorge correspondante.Similar to the hinge parts 5, the implementation of these lock parts 6 is performed by presenting each of said pieces locks, in the folded position of their hinge, facing a front wall, then pushing the wing of recess 19b in the outer groove 16 of said front wall, until the ratchet of the rib in the corresponding groove.

La conception des boîtes de conditionnement selon l'invention et des pièces de liaison 5, 6 de ces dernières permet de garantir, par le choix d'un nombre adéquat de pièces charnières 5 et de pièces verrous 6, et d'un positionnement adéquat de ces pièces de liaison, une parfaite fermeture hermétique des deux moitiés de boîte 1, 1a.The design of the packaging boxes according to the invention and connecting pieces 5, 6 of the latter makes it possible to guarantee, by the choice of an adequate number of hinge parts 5 and lock pieces 6, and of an adequate positioning of these connecting pieces, a perfect hermetic closure of the two box halves 1, 1a.

Avantageusement, les éléments de jonction 3, 4 présentent des ergots 12 pénétrant dans des gorges intérieures pratiquées dans les étriers 21 et pouvant s'encliqueter dans lesdites gorges 19.Advantageously, the connecting elements 3, 4 have lugs 12 penetrating into internal grooves formed in the stirrups 21 and can snap into said grooves 19.

En se référant maintenant aux figures 13 à 14, ces figures montrent un élément de liaison entre les éléments de jonction 2 à 4 formant le rebord périphérique de la boîte et le couvercle 1 ou le fond de ladite boîte, ceci selon une première forme de réalisation dudit élément de liaison. L'élément de liaison est formé par les parties en saillie de forme pyramidale 9 de tous les éléments de jonction 2 à 4 qui se complètent afin de former une forme avantageusement continue sur le pourtour de la boîte de conditionnement.Referring now to Figures 13 to 14 these figures show a connecting element between the connecting elements 2 to 4 forming the peripheral rim of the box and the cover 1 or the bottom of said box, this according to a first embodiment of said connecting element. The connecting element is formed by the pyramidal projecting parts 9 of all the joining elements 2 to 4 which complement one another so as to form an advantageously continuous shape on the periphery of the packaging box.

Le fond ou le couvercle associé à ce côté des éléments de jonction 2 à 4 sont soudés sur l'ensemble des parties en saillie de forme pyramidale 9 formant élément de liaison.The bottom or cover associated with this side of the connecting elements 2 to 4 are welded to all of the projecting portions of pyramidal shape 9 forming a connecting element.

A la figure 14, l'élément de jonction 3 présente une longueur plus grande, ce qui permet une augmentation de la boîte de conditionnement en hauteur. Le couvercle 1 ou le fond de la boîte présente avantageusement une forme de réception 9a de la partie en saillie de forme pyramidale 9 de chaque élément de jonction 3, la partie en saillie de forme pyramidale 9 se trouvant sur la partie recourbée 13 sur sa face en vis-à-vis du fond ou du couvercle 1.To the figure 14 , the joining element 3 has a longer length, which allows an increase in the conditioning box height. The lid 1 or the bottom of the box advantageously has a form of reception 9a of the projecting portion of pyramidal shape 9 of each connecting element 3, the projecting portion of pyramidal shape 9 being on the curved portion 13 on its face opposite the bottom or lid 1.

En se référant maintenant aux figures 15 à 16, ces figures montrent un élément de liaison 10 entre les éléments de jonction 2 à 4 formant le rebord périphérique de la boîte, d'une part, et le couvercle ou le fond de ladite boîte, d'autre part, ceci selon une seconde forme de réalisation dudit élément de liaison.Referring now to Figures 15 to 16 these figures show a connecting element 10 between the connecting elements 2 to 4 forming the peripheral rim of the box, on the one hand, and the lid or the bottom of said box, on the other hand, this in a second form embodiment of said connecting element.

L'élément de liaison est un piton 10 et fait partie d'une succession de pitons 10 sur le pourtour de la boîte, au moins un piton 10 et de préférence plusieurs pitons étant portés par chaque élément de jonction 2, 3, 4. Comme montré à la figure 16, le couvercle 1 ou le fond de la boîte présente avantageusement une forme de réception 10a d'un piton 10 d'un élément de jonction 3.The connecting element is a peak 10 and is part of a succession of pitons 10 around the periphery of the box, at least one pin 10 and preferably several pitons being carried by each connecting element 2, 3, 4. shown in the figure 16 , the cover 1 or the bottom of the box advantageously has a form of reception 10a of a peak 10 of a connecting element 3.

Les figures 17 et 18 montrent une troisième forme de réalisation de la solidarisation d'éléments de jonction 2c, 3c, 4c avec le couvercle ou le fond 1 c d'une boîte modulable.The Figures 17 and 18 show a third embodiment of the joining junction elements 2c, 3c, 4c with the lid or the bottom 1 c of a modular box.

A la figure 18, l'élément de jonction représenté 3c est sensiblement similaire à l'élément de jonction 3 représenté à la figure 16 à la différence près qu'à la place du piton 10 il présente un plot d'accrochage 10d remplaçant ledit piton, donc avantageusement plusieurs plots d'accrochage 10d pour un même élément de jonction 3c. L'élément de jonction 3c présente aussi une partie d'extrémité 13 tournée vers le couvercle ou le fond 1c, sensiblement perpendiculaire au(x) plot(s) 10d en portant le ou les plots 10d. La partie d'extrémité 13 pénètre dans un élément intermédiaire de liaison 27 disposé entre d'une part l'élément de jonction 3c et d'autre part le couvercle ou le fond 1c. L'élément intermédiaire de liaison 27 est sous la forme d'un élément d'attache rapide présentant un logement 31, 32 à ses extrémités opposées, un logement 31 recevant la partie d'extrémité 13 de l'élément de jonction 3c tandis que l'autre logement 32 reçoit une partie de bord du couvercle ou du fond 1c. L'élément intermédiaire de liaison 27 comprend aussi au moins un orifice 30 pour la réception du ou de chaque plot 10d de l'élément de jonction 3c qui se clippe dans ledit orifice 30.To the figure 18 the joining element 3c is substantially similar to the joining element 3 shown in FIG. figure 16 with the difference that instead of the pin 10 it has a hooking pad 10d replacing said pin, so advantageously several tie pads 10d for the same connecting element 3c. The joining element 3c also has a part end 13 facing the cover or the bottom 1c, substantially perpendicular to the (x) pad (s) 10d carrying the pad or pads 10d. The end portion 13 penetrates into an intermediate connecting element 27 disposed between on the one hand the junction element 3c and on the other hand the cover or the bottom 1c. The intermediate connecting element 27 is in the form of a quick coupling member having a housing 31, 32 at its opposite ends, a housing 31 receiving the end portion 13 of the connecting member 3c while the Another housing 32 receives an edge portion of the lid or bottom 1c. The intermediate connecting element 27 also comprises at least one orifice 30 for receiving the or each stud 10d of the connecting element 3c which is clipped into said orifice 30.

Ainsi le plot peut être solidarisé directement, quand il n'y a pas d'élément intermédiaire de liaison 27 ou indirectement, quand il y a un élément intermédiaire de liaison 27, avec ledit couvercle ou fond 1c.Thus the stud can be directly secured, when there is no intermediate connecting element 27 or indirectly, when there is an intermediate connecting element 27, with said lid or bottom 1c.

Les figures 19 à 21 montrent différents éléments intermédiaires de liaison 27 à 29 présentant cependant toujours des logements opposés 31 et 32 ainsi qu'au moins un orifice 30 de clippage tandis que la figure 22 montre un élément de jonction 3c présentant au moins un plot d'accrochage 10d sur une partie d'extrémité 13 recourbée à angle droit par rapport au corps de l'élément de jonction 3c.The Figures 19 to 21 show various intermediate connecting elements 27 to 29, however, always having opposed housings 31 and 32 and at least one clipping hole 30 while the figure 22 shows a junction element 3c having at least one attachment stud 10d on an end portion 13 curved at right angles to the body of the connecting member 3c.

Une telle boîte est facilement modulable en prenant différents éléments de jonction qui eux-mêmes peuvent servir à la conception de différentes boîtes.Such a box is easily adjustable by taking different connecting elements which themselves can be used for the design of different boxes.

En se référant à toutes les figures, un procédé de fabrication d'une boîte B de conditionnement selon la présente invention, ladite boîte présentant un fond 1a, un couvercle 1 et un rebord périphérique raccordant le fond 1a au couvercle 1, peut comprendre les étapes suivantes :
