Abstract

The procedure consists of cutting and scoring a sheet of cardboard along appropriate lines and then stamping it between a die (20) and a matrix (30) to make the container of the required shape. The initial sheet is of greater dimensions than the container to be made from it, and its cut and scored lines are situated so that they form a number of linked components of the container, e.g. sides and a base, some of which are glued together after shaping. The containers can be made with adjoining or separate panels which forms a top of each of the containers. A single sheet of cardboard can be used for a whole series of containers, cut from it in rows. <IMAGE>

Description

On sait que beaucoup de contenants doivent maintenir au plus près de leur contour des petits objets de toutes sortes : flacons de parfum, confiseries, ampoules et autres objets fragiles ou devant être mis en valeur.We know that many containers must maintain as close to their outline small objects of all kinds: perfume bottles, confectionery, light bulbs and other fragile objects or to be highlighted.

Certains objets doivent être placés dans des concavités telles que des barquettes, d

Figure 00010001
autres doivent être maintenus par des reliefs qui ne les enveloppent pas entièrement mais forment des appuis ponctuels judicieusement disposés, ces reliefs étant nommés 〈〈 calages 〉〉.Certain objects must be placed in concavities such as trays,
Figure 00010001
others must be maintained by reliefs which do not entirely envelop them but form judiciously placed point supports, these reliefs being called "wedges".

L utilisation de carton ou autre matériau similaire est difficile en raison de leur indéformabilité intrinsèque, contrairement aux films plastiques qui ne prêtent, notamment, au thermoformage et peuvent ainsi acquérir les formes, même complexes, d un modèle.L use of cardboard or other similar material is difficult because of their intrinsic non-deformability, unlike plastic films which do not lend themselves, in particular, to thermoforming and can thus acquire the forms, even complex, of A model.

Le carton, au contraire, ne peut être mis en forme que par cintrage ou pliage et ne se conforme qu à des volumes développables, c est-à-dire géométriquement réductibles à un plan.Cardboard, on the contrary, can only be shaped by bending or folding and only conforms at developable volumes, c that is to say geometrically reducible to a plane.

En outre, les petits objets supposent que les parties qui doivent les maintenir soient également de petites dimensions.In addition, small objects assume that the parts that must hold them are also small.

Or, l obtention en carton de parties ayant des dimensions faibles entraíne des prix de revient souvent prohibitifs, raison pour laquelle on préfère adopter les matières plastiques.Now, l obtaining cardboard parts having small dimensions often cost prices prohibitive, which is why we prefer to adopt plastics.

Mais les matières plastiques sont plus économiques que le carton à condition d avoir une épaisseur faible. Il est pratiquement impossible, actuellement, de réaliser en matière plastique des articles de conditionnement ayant la tenue et l aspect du carton.But plastics are more economical than cardboard provided have a low thickness. It is practically impossible, at present, to produce plastic articles of packaging having the strength and the appearance of cardboard.

La présente invention apporte une solution nouvelle grâce à laquelle on peut réaliser en carton, ou matériau similaire, des composants de contenants qui ont un prix de revient raisonnable, tout en offrant à la clientèle des qualités de solidité et de présentation esthétique excellentes. The present invention provides a new solution by which it is possible to achieve in cardboard, or similar material, container components that have a cost price reasonable, while offering customers qualities of solidity and aesthetic presentation excellent.

On connaít déjà des contenants qui sont mis en volume à partir d'un flan. C'est le cas, notamment du document US-A-1,782,777 qui décrit une machine permettant d'obtenir des contenants en carton ou matière analogue, formé d'une partie d'un flan découpé, rainé, plié, conformé et maintenu en volume. Mais cette machine prévoit que les flans ne sont pas prédécoupés pour retirer des fractions de carton, les fractions excédentaires étant simplement repliées sur elles-mêmes, en surépaisseur.We already know containers that are set in volume from a blank. It's the case, in particular from document US-A-1,782,777 which describes a machine making it possible to obtain containers of cardboard or similar material, formed from part of a cut, creased, folded blank, shaped and maintained in volume. But this machine provides that the blanks are not pre-cut to remove cardboard fractions, the excess fractions being simply folded back on themselves, in excess thickness.

A cette fin, l invention a pour objet un procédé d'obtention de composants pour contenants en carton ou matière analogue, du type selon lequel on crée des éléments dans un flan par prédécoupe de lignes et par rainage d'autres lignes, caractérise en ce que l'on place le flan prédécoupé et rainé en regard d'un conformateur comprenant une matrice concave d'une part et un emboutisseur convexe d'autre part qui comprennent respectivement autant d'alvéoles et autant de poinçons qu'il y a d'éléments, on met le flan en forme dans la matrice par fracture du flan le long des lignes de prédécoupe et par pliage le long des lignes de rainage afin de former des éléments présentant chacun une partie concave et une partie convexe formées par des parois latérales et par un fond, on maintient en forme le flan notamment par collage de parties rapprochées, on sépare la matrice de l'emboutisseur et l'on retire le flan.To this end, the invention relates to a process for obtaining components for containers of cardboard or similar material, of the type according to which elements are created in a blank by pre-cutting lines and by creasing other lines, characterized in that one places the blank precut and grooved opposite a shaping device comprising a concave matrix on the one hand and a convex stamper on the other hand which respectively comprise as many cells and as many punches as there are elements, the blank shaped in the matrix by fracturing the blank along the precut lines and by folding along the crease lines in order to form elements each having a concave part and a convex part formed by side walls and by a bottom, keeps the blank in shape, in particular by bonding close-together parts, the matrix is separated from the stamper and the blank is removed.

Selon d autres caractéristiques de ce procédé :

  • on maintient chaque élément en volume indépendamment des autres, par collage de pattes mises en regard lors du formage;
  • dans un deuxième flan, on crée autant de découpes qu il y a d éléments déterminés dans le premier flan, on place le deuxième flan dans la matrice de telle place le premier flan sur le deuxième, on met en forme tous ces éléments en provoquant le repliement de parois latérales faisant partie de chaque élément et l on fait pénétrer chaque élément indépendant dans une découpe du deuxième flan afin que celui-ci maintienne en volume tous les éléments, puis on fixe les éléments audit deuxième flan ;

  • on donne au deuxième flan une largeur sensiblement égale à celle du premier flan et une longueur sensiblement double de celle du premier flan, on plie le deuxième flan transversalement à lui-même et on l applique sur les deux faces du premier flan qui est alors pris 〈〈 en sandwich 〉〉, la partie du deuxième flan qui est appliquée contre la face du premier flan sur laquelle apparaissent les parties concaves des éléments, constituant le panneau ;
  • le panneau est plein et recouvre les parties concaves des éléments ;
  • le panneau présente des ouvertures dont les dimensions et les positions correspondent aux parties concaves des éléments ;
  • on applique les pattes en surépaisseur contre le deuxième flan et l on fixe des cales de même épaisseur sur ledit deuxième flan, entre les pattes, afin que l on puisse appliquer le panneau aussi uniformément que possible, à la fois sur les pattes et sur les cales ;
  • on découpe dans le même deuxième flan les éléments et les cales en les séparant par des lignes de prédécoupe, on met les éléments en forme tout en provoquant la séparation desdits éléments et des cales par fracture du deuxième flan le long des lignes de prédécoupe par lesquelles les éléments tiennent aux cales afin de former individuellement les éléments tout en appliquant les cales sur le premier flan ;
  • après formage des éléments, on découpe le deuxième flan autour de chaque élément afin de constituer autant d ensembles composés chacun d un élément en volume et d un cadre sur lequel sont fixées, notamment par collage, des pattes solidaires de chaque paroi latérale ;
  • on crée des découpes dans deux flans différents, on place les deux flans dans la matrice l un sur l autre de telle sorte que les découpes soient en regard des alvéoles, on met en forme tous les éléments en même temps en provoquant le repliement, par rabattement, de parois latérales de chaque élément dont certaines sont prévues sur le premier flan et les autres sur le deuxième flan, et le repliement, par redressement, de volets solidaires des parois latérales afin de constituer un pourtour d un fond, puis on fixe entre eux au moins certains de ces volets placés en partie l un sur l autre.
  • on crée les découpes en ménageant entre elles des séparations formées par des bandes qui constituent un cadre demeurant dans le plan d origine des flans.
According to d other characteristics of this process:

Le procédé selon l invention permet d obtenir des éléments en carton ou autre matériau similaire à partir d un seul flan.The process according to l invention allows obtain cardboard or other similar material from one blank.

Sur ce flan, on pratique des lignes de prédécoupe, des lignes de rainage et, le cas échéant, des ouvertures. Ensuite, on procède à la mise en forme des éléments qui se séparent les uns des autres par rupture des lignes de prédécoupe, sous l effet de la poussée que l on exerce sur chaque élément pour l enfoncer dans un alvéole.On this blank, precut lines, crease lines and, where appropriate, openings are practiced. Then, the elements which separate from each other are shaped by breaking the precut lines, under the thrust effect that l we exercise on each element for l push into a socket.

La rupture des lignes de prédécoupe se fait par traction parallèlement au plan du flan, alors que la poussée s exerce perpendiculairement à ce même plan.The pre-cut lines are broken by pulling parallel to the plane of the blank, while the push s exercises perpendicular to this same plane.

Par conséquent, on met en oeuvre une seule opération sur un seul flan alors que l on obtient une pluralité d éléments mis en volume.Consequently, a single operation is carried out on a single blank while the we obtain a plurality of elements set in volume.

Le maintien en volume peut être obtenu de différentes manières, notamment par collage de pattes rapprochées lors du formage des éléments. Volume maintenance can be obtained in various ways, in particular by bonding of close together legs during the forming of the elements.

On peut donner aux éléments des formes très variées, du moment qu il s agit de formes développables, c est-à-dire susceptibles de provenir du plan du flan, sans déformation 〈〈 gauche 〉〉 pouvant détruire l intégralité du carton.We can give the elements a variety of forms, as long as he s acts of developable forms, c that is to say likely to come from the plan of the blank, without deformation 〈〈 left 〉〉 being able to destroy the entire box.

Sur les figures 1 à 11 on a représenté un premier mode de réalisation de l invention, selon quelques variantes que l on va expliciter.In Figures 1 to 11 there is shown a first embodiment of the invention, according to some variants that l we will explain.

Sur la figure 1, on voit un flan conforme à l invention que l on a représenté sur un fond plus foncé pour mieux faire ressortir ses caractéristiques.In Figure 1, we see a blank conforming to l invention that l we have represented on a darker background to better highlight its characteristics.

Le flan 1 est marqué de lignes de prédécoupe 2 en traits pleins et de lignes de rainage 3 en traits pointillés.The blank 1 is marked with precut lines 2 in solid lines and crease lines 3 in dotted lines.

Ici, certaines des lignes de prédécoupe forment les côtés de polygones et créent des ouvertures 4 laissant apparaítre le fond foncé sur lequel le flan 1 est supposé être appliqué.Here, some of the precut lines form the sides of polygons and create openings 4 revealing the dark background on which the blank 1 is supposed to be applied.

Les éléments ont sensiblement la forme de croix de saint André dont les branches sont divisées par des lignes de rainage devant faciliter le pliage des parties qu elles déterminent et qui sont, pour chaque élément : un fond central 5, quatre parois latérales 6 et quatre pattes 7.The elements have substantially the shape of a cross of Saint Andrew whose branches are divided by lines of creasing to facilitate the folding of the parts that they determine and which are, for each element: a central bottom 5, four side walls 6 and four legs 7.

Les éléments tiennent les uns aux autres par les pattes 7 adjacentes, de sorte que le flan tout entier peut être manipulé comme un ensemble complet.The elements hold to each other by the adjacent tabs 7, so that the blank the whole can be handled as a whole.

Après formage, comme on va le décrire plus loin, chaque élément est composé du fond 5, des quatre parois 6 redressées perpendiculairement au fond 5 et des quatre pattes 7 rabattues par rapport aux parois 6 pour être parallèles au plan du fond 5. Les parois 6 ne sont pas reliées entre elles, les pattes 7 non plus.After forming, as will be described later, each element is composed of the bottom 5, four walls 6 straightened perpendicular to the bottom 5 and four legs 7 folded down relative to the walls 6 to be parallel to the plane of the bottom 5. The walls 6 are not connected between them, the legs 7 either.

Pour maintenir en volume tous les éléments issus du flan 1, en vue de former un composant complet, on utilise un deuxième flan 10 (figure 2) qui est traversé d autant d ouvertures 11 qu il y a d éléments sur le flan 1.To maintain in volume all the elements from the blank 1, in order to form a complete component, a second blank 10 is used (FIG. 2) which is crossed by as many openings 11 qu there is some elements on the blank 1.

Les ouvertures 11 ont des dimensions, des formes et des positions qui correspondent à celles des éléments formés. En d autres termes, les ouvertures 11 sont disposées comme les fonds 5 des éléments.The openings 11 have dimensions, shapes and positions which correspond to those of the elements formed. In d in other words, the openings 11 are arranged like the bottoms 5 of the elements.

Pour le formage des éléments, leur maintien en volume et, donc, la constitution d un composant de contenant, on utilise un conformateur (figures 3 et 4) qui comprend d une part un emboutisseur 20 possédant autant de poinçons 21 qu il y a d éléments et, d autre part, une matrice 30 ayant autant d alvéoles 31 qu il y a de poinçons 21, et donc d éléments. For the forming of the elements, their maintenance in volume and, therefore, the constitution of a container component, a shaper (Figures 3 and 4) is used which includes on the one hand a stamper 20 having as many punches 21 as there is some elements and, d on the other hand, a matrix 30 having as many alveoli 31 qu there are punches 21, and therefore d elements.

Pour la simplicité de l exposé, on n a représenté qu un seul poinçon 21 et un seul alvéole 31, pour le formage d un seul élément mais, comme on l a précisé plus haut, le procédé de l invention s applique à l obtention simultanée de plusieurs éléments.For the simplicity of the exposed, we n represented that a single punch 21 and a single cell 31, for forming only one element but, as we clarified above, the process of the invention s apply to obtaining several elements simultaneously.

Sur la matrice 30, on dispose d abord le deuxième flan 10 en le positionnant de telle sorte que ses ouvertures 11 soient chacune en regard d un alvéole 31, puis on place le premier flan 1 sur le deuxième, en le positionnant de telle sorte que le fond 5 de chaque élément soit en regard d une ouverture 11.On the matrix 30, we have first the second blank 10 by positioning it so that its openings 11 are each opposite a cell 31, then the first blank 1 is placed on the second, positioning it so that the bottom 5 of each element is opposite an opening 11.

On abaisse l emboutisseur 20 afin que tous les poinçons 21 poussent le fond 5 de tous les éléments vers le fond de l alvéole 31.We lower the stamper 20 so that all the punches 21 push the bottom 5 of all the elements towards the bottom of the cell 31.

Ce faisant, le fond 5 exerce une traction sur les parois 6 et celles-ci exercent une traction sur les pattes 7.In doing so, the bottom 5 exerts a traction on the walls 6 and these exert a leg traction 7.

Comme pour deux éléments adjacents, les tractions dues au poinçon 21 correspondant sont contraires, elles provoquent la rupture des lignes de prédécoupe 2, ce qui sépare les éléments les uns des autres et les rend tous indépendants.As for two adjacent elements, the pulls due to the corresponding punch 21 are contrary, they cause the break of the precut lines 2, which separates the elements from each other and makes them all independent.

Les parois 6 peuvent donc suivre le fond 5.The walls 6 can therefore follow the bottom 5.

Celui-ci se place sur le fond 32 de l alvéole 31 tandis que les parois 6 se plient selon les lignes de rainage 3 et se placent contre les parois 33 de l alvéole 31.This is placed on the bottom 32 of the cell 31 while the walls 6 fold along the crease lines 3 and are placed against the walls 33 of the cell 31.

Les pattes 7 suivent les parois 6 mais restent parallèles à elles-mêmes, le poinçon 21 les obligeant à se plier selon les lignes de rainage 3 qui les séparent des parois 6.The legs 7 follow the walls 6 but remain parallel to themselves, the punch 21 forcing them to bend along the crease lines 3 which separate them from the walls 6.

On remarque que le poinçon 21 présente des logements 22 dont la profondeur est sensiblement égale à l épaisseur du carton constituant le premier flan 1, afin de pouvoir contenir les pattes 7 et les presser contre le deuxième flan 10 (figure 4).Note that the punch 21 has housings 22 whose depth is substantially equal to l thickness of the cardboard constituting the first blank 1, in order to be able to contain the tabs 7 and press them against the second blank 10 (FIG. 4).

On comprend que le deuxième flan 10 enserre chaque élément par sa périphérie déterminée par les parois 6, redressées du fond 5 perpendiculairement à lui.It is understood that the second blank 10 encloses each element by its periphery determined by the walls 6, straightened from the bottom 5 perpendicularly to it.

Cependant, cela n est pas suffisant pour assurer la fixation des éléments sur le deuxième flan 10.However, this n is not sufficient to secure the elements on the second blank 10.

Cette fixation peut être obtenue par collage, notamment en prévoyant un adhésif soit sous le premier flan 1, soit sur le deuxième flan 10. Mais, étant donné le mouvement de glissement relatif des deux flans l un sur l autre lors du formage des éléments, il faut éviter un collage irrégulier et l on peut, par exemple, prévoir un adhésif sec thermoactif qui n est rendu effectif qu après formage des éléments, par chauffage du poinçon, ce qui est à la portée de l homme de métier. This fixing can be obtained by gluing, in particular by providing an adhesive either under the first blank 1, or on the second blank 10. But, given the relative sliding movement of the two blanks l one on l other when forming the elements, avoid irregular bonding and the one can, for example, provide a dry thermoactive adhesive which n is made effective that after forming the elements, by heating the punch, which is within the reach of tradesman.

Quand ces opérations sont terminées, le composant terminé se présente sur une face comme représenté sur la figure 6 et par son autre face comme représenté sur la figure 7.When these operations are finished, the finished component is presented on one side as shown in FIG. 6 and by its other face as shown in FIG. 7.

La face 〈〈 utile 〉〉 est, ici, celle qui présente la partie convexe des éléments car on utilise les éléments en relief comme calage pour des objets devant être immobilisés dans un contenant de tout type connu tel qu une boíte, un coffret ou un étui. On a représenté en pointillés sur la figure 6 un tel objet a bloqué par quatre éléments.The face 〈〈 useful 〉〉 is, here, that which presents the convex part of the elements because the elements in relief are used as wedging for objects to be immobilized in a container of any known type such as a box, a box or a case. There is shown in dotted lines in FIG. 6 such an object blocked by four elements.

Sur son autre face, le composant présente la partie concave des éléments et les pattes 7 collées au deuxième flan 10.On its other side, the component has the concave part of the elements and the legs 7 glued to the second blank 10.

Pour certaines applications, on peut se contenter de laisser apparentes les pattes 7, comme cela se voit sur la figure 7, ce qui est le cas lorsque l ensemble flan 10-éléments est collé contre une paroi car, alors, la face apparente sur la figure 7 reste dissimulée.For certain applications, it is sufficient to leave the legs 7 visible, as can be seen in FIG. 7, which is the case when the 10-element blank assembly is glued against a wall because, then, the visible face in FIG. 7 remains concealed.

Pour d autres applications, on ne peut se contenter de cet aspect brut et il faut soigner la finition, ce que l on obtient en appliquant un panneau 40 uni ou décoré et qui, de toutes façons, cache toute la face du deuxième flan et les pattes collées 7.For other applications, we cannot be satisfied with this raw aspect and we must take care of the finish, what the this is obtained by applying a plain or decorated panel 40 which, in any case, hides the entire face of the second blank and the glued legs 7.

Les pattes 7 étant en surépaisseur sur le deuxième flan 10, le panneau 40 est appliqué sur une surface d autant plus irrégulière que le carton constituant le premier flan 1 est plus épais, ce qui peut provoquer des ondulations inesthétiques du panneau 40, comme on l évoque sur la figure 9.The legs 7 being in excess thickness on the second blank 10, the panel 40 is applied to a surface d as much more irregular as the cardboard constituting the first blank 1 is thicker, which can cause unsightly undulations of the panel 40, as we shown in Figure 9.

Pour atténuer ce défaut, on conserve le maximum de surface lors du marquage du premier flan 1.To mitigate this defect, the maximum surface area is retained when marking the first blank 1.

En se reportant à la figure 1, on voit qu il est possible, par exemple, de conserver les parties de carton 15 qui avaient été retirées pour laisser apparaítre des ouvertures 4 en forme de losange, de plus grande étendue que les petites ouvertures carrées (figure 8).Referring to Figure 1, we see that it is possible, for example, to keep the parts of cardboard 15 which had been removed to reveal apertures 4 in the form of a diamond, of greater extent than the small square openings (Figure 8).

Il est également possible de laisser subsister un cadre 16 présentant des parties triangulaires 17 équivalents à des demi-losanges 15, ainsi que des parties linéaires 18 et des languettes 19.It is also possible to leave a frame 16 having parts triangular 17 equivalent to half-diamonds 15, as well as linear parts 18 and tabs 19.

Le tout provenant du premier flan 1, a évidemment la même épaisseur que les pattes 7 et vient compenser en grande partie les espaces laissées par le retrait des fonds 5 et des parois latérales 6 lors du formage des éléments.The whole from the first blank 1, obviously has the same thickness as the legs 7 and largely compensates for the spaces left by the withdrawal of the bottoms 5 and of the walls lateral 6 during the forming of the elements.

Le panneau 40 présente alors peu ou pas d ondulations, comme on l évoque sur la figure 10. The panel 40 then has little or no d ripples, as we evoked in Figure 10.

On remarque sur les figures 7 à 10 que le panneau 40 recouvre l ouverture de la partie concave des éléments, ce qui suppose que l on considère leur partie convexe comme seule partie utile, ce qui est bien le cas lorsque l on utilise le composant comme calage (figure 6).Note in Figures 7 to 10 that the panel 40 covers the opening of the concave part of the elements, which supposes that the we consider their convex part as the only useful part, which is the case when l we use the component as calibration (figure 6).

Mais l on pourrait aussi utiliser les parties concaves des éléments comme des alvéoles destinés à recevoir un ou plusieurs articles, ou bien un produit en vrac.But one could also use the concave parts of the elements such as cells intended to receive one or more articles, or else a bulk product.

Dans ce cas, le panneau 40 doit être traversé d ouvertures centrées sur les éléments afin de cacher les pattes 7 tout en laissant libre l accès à l intérieur des éléments.In this case, the panel 40 must be crossed d openings centered on the elements in order to hide the legs 7 while leaving free the access to interior of the elements.

Sur les figures 7 à 10, le panneau 40 est un panneau indépendant, rapporté et fixé sur les flans 1 et 10.In FIGS. 7 to 10, the panel 40 is an independent panel, attached and fixed to blanks 1 and 10.

Sur la figure 11, on a représenté une variante de réalisation du panneau de recouvrement qui consiste à prévoir un deuxième flan 10 de longueur à peu près double pour disposer de deux parties 10a et 10b séparées par une ligne de pliage transversale 10c.In FIG. 11, an alternative embodiment of the covering panel has been shown, which consists in providing a second blank 10 of approximately double length in order to have two parts 10 a and 10 b separated by a transverse fold line 10 c .

Après formation des éléments et retrait de l ensemble du conformateur, le deuxième flan 10 est alors plié selon la ligne 10c, comme indiqué par la flèche, pour être appliqué sur le premier flan 1 et sur le verso de sa partie 10a.After formation of the elements and removal of the assembly of the former, the second blank 10 is then folded along line 10 c , as indicated by the arrow, to be applied to the first blank 1 and to the back of its part 10 a .

Ici, on a illustré le cas où l on souhaite accéder à l intérieur des éléments, en prévoyant des ouvertures 10d centrées chacune sur un élément, la partie 10b du deuxième flan 10 ne devant masquer que les pattes 7.Here, we illustrated the case where l we want to access inside the elements, by providing openings 10 d each centered on an element, the part 10 b of the second blank 10 should only mask the tabs 7.

En se reportant maintenant aux figures 12 à 15, on voit un élément conforme à l invention constitué par une barquette simple, issue d un flan 50 découpé et éventuellement imprimé, représenté sur la figure 12.Referring now to Figures 12 to 15, we see an element according to the invention consisting of a simple tray, derived from a blank 50 cut and optionally printed, shown in FIG. 12.

Sur ce flan 50, on pratique des lignes de prédécoupe longitudinales 51 et transversales 52 ainsi que des lignes de rainage.On this blank 50, longitudinal precut lines 51 and transverse lines are practiced 52 as well as creasing lines.

Des lignes de rainage 53 déterminent, pour la barquette devant résulter de chaque ébauche, un fond 54 et des parois latérales opposées 55 et 56, tandis que des lignes de rainage 57 déterminent des segments opposés 58 et 59 devant déterminer un cadre comme on va le décrire ci-après.Creasing lines 53 determine, for the tray to result from each blank, bottom 54 and opposite side walls 55 and 56, while crease lines 57 determine opposite segments 58 and 59 to determine a frame as we will describe below.

Après avoir pratiqué ces lignes de prédécoupe 51 et 52 ainsi que ces lignes de rainage 53 et 57, on procède à la mise en forme des ébauches.After having practiced these precut lines 51 and 52 as well as these crease lines 53 and 57, the blanks are shaped.

Pour cela, on dispose le flan 50 tout entier en regard d un conformateur que l on ne décrira pas en détails car il est du même type que celui décrit en regard des figures 3 et 4. For this, we have the entire blank 50 next to a conformator that l it will not be described in detail since it is of the same type as that described with reference to FIGS. 3 and 4.

Lorsque les poinçons agissent, ils provoquent le pliage des parois 55 et 56 〈〈 vers le haut 〉〉 pour border le fond 54 et le pliage opposé 〈〈 vers le bas 〉〉 des segments 58 et 59, après que les ébauches se soient séparées les unes des autres par rupture des lignes de prédécoupe 51 et 52, sous l effet de la poussée que chaque poinçon exerce sur chaque ébauche, à l aplomb du fond 54.When the punches act, they cause the folding of the walls 55 and 56 〈〈 upward 〉〉 to border the bottom 54 and the opposite folding 〈〈 downward 〉〉 of the segments 58 and 59, after the blanks have separated each other by breaking the precut lines 51 and 52, under the effect of the thrust that each punch exerts on each blank, at the plumb from the bottom 54.

Comme expliqué précédemment, la rupture des lignes de prédécoupe 51 et 52 se fait par traction parallèlement au plan du flan 50, alors que la poussée des poinçons s exerce perpendiculairement à ce même plan.As explained above, the breaking of the precut lines 51 and 52 is done by traction parallel to the plane of the blank 50, while the thrust of the punches s exercises perpendicular to this same plane.

Par conséquent, on met en oeuvre une seule opération sur un seul flan 50 alors que l on obtient une pluralité de barquettes mises en volume.Consequently, a single operation is carried out on a single blank 50 while the a plurality of trays set in volume is obtained.

Le maintien en volume est obtenu par collage des segments voisins 58 et 59 rapprochés lors du formage des barquettes, ou plus généralement par tout moyen d assemblage et, notamment, par thermoadhésion.Maintaining volume is obtained by bonding neighboring segments 58 and 59 close together during the formation of the trays, or more generally by any means of assembly and, in particular, by thermoadhesion.

Avant passage au conformateur, le flan 50 présente donc une pluralité d ébauches fixées les unes aux autres et après passage au conformateur, on obtient des barquettes individuelles et indépendantes les unes des autres qui se présentent chacune comme cela est représenté sur les figures 13 à 15.Before passing to the shaper, the blank 50 therefore has a plurality of blanks fixed to each other and after passing through the shaper, individual and independent trays from each other are obtained which are each presented as shown in FIGS. 13 to 15.

On voit que la longueur des segments 58 d une part et la longueur des segments 59 d autre part sont calculées pour qu un segment 59 recouvre l extrémité des deux segments 58 contigus après formage.We see that the length of the segments 58 d one part and the length of the segments 59 d on the other hand are calculated so that a segment 59 covers the end of the two contiguous segments 58 after forming.

Ce recouvrement est utilisé pour fixer entre eux les segments 58 et 59, notamment par collage.This covering is used to fix the segments 58 and 59 together, in particular by collage.

En se reportant maintenant aux figures 16 à 19, on voit un élément conforme à l invention constitué par une barquette simple, issue d un flan 60 découpé et éventuellement imprimé, représenté sur la figure 16.Referring now to Figures 16 to 19, we see an element according to the invention consisting of a simple tray, derived from a blank 60 cut and optionally printed, shown in FIG. 16.

Sur ce flan 60, on pratique des lignes de prédécoupe longitudinales 61 et transversales 62 ainsi que des lignes de rainage.On this blank 60, longitudinal precut lines 61 and transverse lines are practiced 62 as well as creasing lines.

Des lignes de rainage 63 déterminent, pour la barquette devant résulter de chaque ébauche, un fond 64 et des parois latérales opposées 65 et 66, tandis que des lignes de rainage 67 déterminent des pattes de collage 68 et 69 devant coopérer avec un cadre comme on va le décrire ci-après. Creasing lines 63 determine, for the tray to result from each blank, bottom 64 and opposite side walls 65 and 66, while creasing lines 67 determine the gluing tabs 68 and 69 which must cooperate with a frame as will be seen. describe below.

Après avoir pratiqué ces lignes de prédécoupe 61 et 62 ainsi que ces lignes de rainage 63 et 67, on procède à la mise en forme des ébauches.After having practiced these precut lines 61 and 62 as well as these crease lines 63 and 67, the blanks are shaped.

Pour cela, on dispose le flan 60 tout entier en regard d un conformateur que l on ne décrira pas en détails car il est du même type que celui décrit en regard des figures 3 et 4.For this, we have the entire blank 60 next to a conformator that l it will not be described in detail since it is of the same type as that described with reference to FIGS. 3 and 4.

Lorsque les poinçons agissent, ils provoquent le pliage des parois 65 et 66 〈〈 vers le haut 〉〉 pour border le 69, après que les ébauches se soient séparées les unes des autres par rupture des lignes de prédécoupe 61 et 62, sous l effet de la poussée que chaque poinçon exerce sur chaque ébauche, à l aplomb du fond 64.When the punches act, they cause the walls 65 and 66 to fold 〈〈 upwards 〉〉 to border the 69, after the blanks have separated from each other by breaking the precut lines 61 and 62, under the effect of the thrust that each punch exerts on each blank, at the plumb from the bottom 64.

Comme expliqué précédemment, la rupture des lignes de prédécoupe 61 et 62 se fait par traction parallèlement au plan du flan 60, alors que la poussée des poinçons s exerce perpendiculairement à ce même plan.As explained previously, the breaking of the precut lines 61 and 62 is done by traction parallel to the plane of the blank 60, while the thrust of the punches s exercises perpendicular to this same plane.

Par conséquent, on met en oeuvre une seule opération sur un seul flan 60 alors que l on obtient une pluralité de barquettes mises en volume, celles-ci, néanmoins n étant pas simultanément maintenues en volume, contrairement au mode de réalisation des figures 12 à 15.Consequently, a single operation is carried out on a single blank 60 while the we obtain a plurality of trays placed in volume, these, however n not being simultaneously maintained in volume, unlike the embodiment of FIGS. 12 to 15.

Le maintien en volume est obtenu, ici, par collage des pattes 68 et 69, repliées lors du formage des barquettes, contre un cadre 70 issu d un second flan (non représenté).Maintaining volume is obtained, here, by bonding tabs 68 and 69, folded during the formation of the trays, against a frame 70 from a second blank (not shown).

Ce second flan comprend autant de cadres qu il y a d ébauches de barquettes sur le flan 60. La partie centrale de chaque cadre 70 est évidée et ils tiennent les uns aux autres par leurs bords.This second blank includes as many frames as there is some blanks of trays on the blank 60. The central part of each frame 70 is hollowed out and they hold to each other by their edges.

Avant passage au conformateur, les deux flans sont superposés et lors du formage des ébauches de barquettes, elles pénètrent dans la partie centrale évidée du cadre 70, les pattes 68 et 69 s appliquant chacune contre l un des côtés du cadre et y étant fixées, notamment par collage simultané.Before passing to the conformator, the two blanks are superimposed and during the forming of the blanks of trays, they penetrate into the hollowed-out central part of the frame 70, the legs 68 and 69 s each applying against the one of the sides of the frame and being fixed thereto, in particular by simultaneous bonding.

A noter qu avec ce mode de réalisation, les cadres ne sont pas séparés les uns des autres automatiquement puisqu ils ne subissent aucun effort de traction dans leur plan puisqu ils ne subissent aucune formation, aucune déformation.Note that with this embodiment, the frames are not separated from each other automatically since they do not undergo any tractive effort in their plane since they undergo no training, no deformation.

Il faut donc les découper, ce qui est obtenu facilement comme le pratique couramment l homme de métier, en munissant l emboutisseur de lames coupantes et la matrice de leurs contreparties habituelles.They must therefore be cut out, which is easily obtained as is the practice in practice. tradesman, providing the cutting blade stamper and the matrix of their usual counterparts.

La présence de lignes de prédécoupes séparant les cadres les uns des autres n est donc pas indispensables avec ce mode de réalisation. The presence of pre-cut lines separating the frames from each other n is therefore not essential with this embodiment.

En se reportant maintenant aux figures 20 à 22, on voit un mode de réalisation de l invention permettant d obtenir un plateau alvéolé pour le calage individuel de petits articles tels que des bonbons et confiseries.Referring now to Figures 20 to 22, we see an embodiment of the invention allowing obtain a honeycomb tray for the individual wedging of small items such as candies and confectionery.

Ce plateau est obtenu en une seule opération de formage, à partie de deux flans coordonnés.This plate is obtained in a single forming operation, from two blanks coordinated.

Sur la figure 20, on voit un premier flan 80, présentant une pluralité d ébauches et entaillé, à ce effet, de lignes de découpes parallèles 8 et de lignes de découpe 82 perpendiculaires aux précédentes et reliées par une ligne oblique 83, donnant à cet ensemble de trois lignes 82-83 une forme sensiblement en 〈〈Z 〉〉.In Figure 20, we see a first blank 80, having a plurality of blanks and notched, for this purpose, with parallel cut lines 8 and cut lines 82 perpendicular to the previous ones and connected by an oblique line 83, giving this set of three lines 82-83 a shape substantially in 〈〈 Z 〉〉 .

Des lignes de rainage 84 parallèles entre elles, joignent les extrémités de deux lignes de découpe 81 et des lignes de rainage 85 prolongeant les lignes de découpe 82 jusqu'à la ligne de découpe 81 voisine.Grooving lines 84 parallel to each other, join the ends of two lines cutting lines 81 and creasing lines 85 extending the cutting lines 82 to the line cutting 81 neighbor.

Les lignes de découpe 81 et les lignes de rainage 84 déterminent ensemble un cadre 86 dont les côtés sont réunis par des segments perpendiculaires, ce cadre 86 étant destiné à rester plan et en une seule pièce.The cut lines 81 and the crease lines 84 together define a frame 86 whose sides are joined by perpendicular segments, this frame 86 being intended to remain plan and in one piece.

On distingue ainsi, pour chaque ébauche, deux parois opposées 87 et deux volets trapézoïdaux 88.There are thus, for each blank, two opposite walls 87 and two flaps trapezoidal 88.

Sur la figure 21, on voit un second flan 90 traversé d ouvertures 91, entaillé de lignes de découpe 92 réunissant, pour chaque ébauche, deux ouvertures 91 et marqué de lignes de rainage parallèles 93 à raison de quatre par ébauche.In Figure 21, we see a second blank 90 crossed by openings 91, notched with cutting lines 92 joining, for each blank, two openings 91 and marked with parallel creasing lines 93 at the rate of four per blank.

Le grand côté extérieur des ouvertures 91 et les lignes de rainage extérieures 93, déterminent un cadre 94 dont les côtés sont réunis par des segments perpendiculaires, ce cadre 94 étant destiné à rester plan et en une seule pièce.The large outer side of the openings 91 and the outer crease lines 93, determine a frame 94 whose sides are joined by perpendicular segments, this frame 94 being intended to remain flat and in one piece.

On distingue ainsi, pour chaque ébauche, deux parois trapézoïdales opposées 95 et deux volets rectangulaires 96.There are thus, for each blank, two opposite trapezoidal walls 95 and two rectangular shutters 96.

Pour le formage de l ensemble du plateau alvéolé, on superpose les deux flans 80 et 90 dont les cadres respectivement 86 et 94 se superposent parfaitement, ainsi que les segments perpendiculaires qui réunissent leurs côtés, de telle sorte que les parois 95 et les volets 96 sont placés sur et contre les parois 87 et les volets 88. For forming the together with the honeycombed plate, the two blanks 80 and 90 are superimposed, the frames 86 and 94 respectively of which overlap perfectly, as well as the perpendicular segments which join their sides, so that the walls 95 and the flaps 96 are placed on and against the walls 87 and the flaps 88.

La poussée du conformateur a pour effet d agir simultanément sur les deux flans, de telle manière que les parois 95 se plient 〈〈 vers le bas 〉〉 selon les lignes extérieures 93 et poussent les parois 87 qui se plient de la même manière selon les lignes 84, tandis que les volets 96 se séparent selon la ligne 92, restent parallèles à eux-mêmes grâce aux lignes 93 intérieures et poussent les volets 88. Ceux-ci se séparent selon la ligne en Z 82-83-82 et restent parallèles à eux-mêmes grâce aux lignes 85.The thrust of the conformator has the effect of act simultaneously on the two blanks, so that the walls 95 fold 〈〈 down 〉〉 along the outer lines 93 and push the walls 87 which fold in the same way along the lines 84, while the flaps 96 separate along line 92, remain parallel to themselves thanks to interior lines 93 and push the flaps 88. These separate along line Z 82-83-82 and remain parallel to themselves thanks to lines 85 .

Ainsi, pour chaque alvéole résultant d une ébauche, on obtient un cadre 86-94, quatre parois latérales 87-95 et un pourtour de fond formé de quatre volets 88-96.Thus, for each cell resulting from a blank, one obtains a frame 86-94, four side walls 87-95 and a bottom periphery formed by four flaps 88-96.

Le fond de chaque alvéole n est donc pas intégral, mais présente une ouverture centrale 100.The bottom of each cell n is therefore not integral, but has a central opening 100.

Ce mode de réalisation peut être adopté pour réaliser un plateau alvéolé destiné au calage et à la présentation de petits objets solides qui sont compatibles avec la présence de l ouverture 100 du fond de chaque alvéole.This embodiment can be adopted to produce a honeycomb tray intended for wedging and for the presentation of small solid objects which are compatible with the presence of the opening 100 of the bottom of each cell.

C est le cas, en particulier, des confiseries de chocolat.VS this is the case, in particular, for chocolate confectionery.

L invention trouve de nombreuses application, tant dans les produits alimentaires que non alimentaires, surtout lorsque l on veut obtenir à la fois un calage efficace et une bonne présentation.L The invention finds many applications, both in food and non-food products, especially when the we want to obtain both an efficient setting and a good presentation.
