Abstract

The cut-out blank (10) comprises base panels (18, 20) which can be superimposed, one of which (18) has traversing openings (30) whilst the other (20) has, in coincidence with the said openings, tongues (32) which comprise a central body (35), assembled with the rest of the panel along a folding line, and side wings capable of being folded and of being elastically deployed, the said central body having dimensions suitable for passing through the said openings (30).

Description

La présente invention se raporte au domaine de l'emballage et au conditionnement par groupes de récipients, par exemple de récipients de forme rétrécie tels que des pots ou équivalents. The present invention relates to the field of packaging and packaging by groups of containers, for example containers of narrowed shape such as pots or the like.

Certains produits comme, par exemple, les yaourts, flans et similaires, sont généralement commercialisés dans des récipients en matière plastique en forme de pots rétrécis, légèrement plus étroits à la base et plus larges à la bouche. En général, plusieurs de ces pots sont enfermés ensemble dans une bande de carton repliée qui porte des inscriptions ou dessins illustratifs ou publicitaires. Certain products such as, for example, yogurts, custards and the like, are generally sold in plastic containers in the form of shrunk jars, slightly narrower at the base and wider at the mouth. In general, several of these pots are enclosed together in a folded strip of cardboard which bears inscriptions or illustrations or advertising drawings.

On connait différents types de bandes ou emballages en carton formés à partir d'un flan découpé ; en général, pour des pots rétrécis conditionnés en files juxtaposées, on utilise des emballages en carton qui forment un gradin séparateur entre les bases des pots des files juxtaposées, de manière à maintenir ces pots dans la position correcte, avec leurs bases espacées les unes des autres et en appui sur le même plan. We know different types of strips or cardboard packaging formed from a cut blank; in general, for shrunk pots packaged in juxtaposed rows, cardboard packaging is used which forms a separating step between the bases of the jars of the juxtaposed rows, so as to maintain these jars in the correct position, with their bases spaced apart others and on the same plane.

Ces emballages en carton sont généralement fournis par l'industrie cartonnière sous une forme à plat, avec la partie en forme de gradin séparateur préformée et pré-encollée. These cardboard packaging is generally supplied by the cardboard industry in a flat form, with the part in the form of a separating step preformed and pre-glued.

Malheureusement, le flan découpé préformé et pré-encollé a un coût supérieur à celui du flan découpé en feuille et l'accroissement de prix est sensible lorsqu'on conditionne quotidiennement de grandes quantités de produits en pots comme, par exemple, des yaourts etc.. Unfortunately, the preformed and pre-glued cut blank has a higher cost than the cut blank and the price increase is appreciable when large quantities of products in jars, such as yogurts, etc., are packaged daily. .

On propose aussi actuellement des flans découpés en feuille ayant une forme d'ensemble sensiblement rectangulaire, de préférence avec des rainurages et des prédécoupes, et, une fois convenablement pliés, ces flans présentent, en coupe, une forme possédant un gradin séparateur de section triangulaire, ce gradin faisant saillie sur la base du flan monté ; également dans ce cas, on observe une plus forte consommation de carton que dans la solution qui fait l'objet de l'invention. Blanks cut into sheets are also currently proposed having a substantially rectangular overall shape, preferably with grooves and precuts, and, once suitably folded, these blanks have, in section, a shape having a separating step of triangular section. , this step projecting from the base of the mounted blank; also in this case, a higher consumption of cardboard is observed than in the solution which is the subject of the invention.

Le but de l'invention est en effet de réaliser un emballage présenté sous la forme d'une feuille plane qui enveloppe les pots sans créer de gradins séparateurs centraux qui entratneraient d'inévitables accroissements de la consommation de carton en raison de leur développement, tout en maintenant cependant les pots solidement positionnés. The object of the invention is in fact to produce a packaging presented in the form of a flat sheet which envelops the pots without creating central separating steps which would lead to inevitable increases in the consumption of cardboard due to their development, all keeping the pots firmly in place.

Ce but est atteint par un flan découpé pour le conditionnement d'éléments du type pot, qui comprend un panneau supérieur, deux panneaux latéraux reliés au panneau supérieur le long de lignes de pliage et des panneaux de base reliés aux panneaux latéraux le long de lignes de pliage, caractérisé en ce que lesdits panneaux de base sont au nombre de deux, chacun étant solidaire d'un panneau latéral, un premier panneau de base présentant des ouvertures traversantes espacées les unes des autres, un second panneau de base présentant des languettes de blocage, chaque languette comprenant un corps central assemblé au reste du panneau le long d'une ligne de pliage, et au moins une ailette de retenue latérale apte à se plier et à se détendre élastiquement, ledit corps central ayant une forme et des dimensions qui le rendent apte à passer à travers lesdites ouvertures, les positions desdites languettes et desdites ouvertures se correspondant mutuellement. This object is achieved by a cut blank for the packaging of pot-like elements, which comprises an upper panel, two side panels connected to the upper panel along fold lines and base panels connected to the side panels along lines. folding, characterized in that there are two said base panels, each being integral with a side panel, a first base panel having through openings spaced apart from one another, a second base panel having tabs of locking, each tab comprising a central body assembled to the rest of the panel along a fold line, and at least one lateral retaining fin capable of folding and of elastically relaxing, said central body having a shape and dimensions which make it suitable for passing through said openings, the positions of said tongues and said openings corresponding to each other.

En d'autres termes, le flan découpé comprend deux pans ou panneaux extrêmes dont l'un présente des ouvertures traversantes, l'autre présente des languettes de retenue prédécoupées, qui possèdent une partie centrale et des ailettes articulées à charnière sur leurs cô- tés opposés, la partie centrale étant de dimensions aptes à passer à travers l'ouverture du premier pan, de sorte qu'après avoir franchi l'ouverture correspondante, les ailettes s'écartent sous l'effet de l'élasticité de la matière, en verrouillant ainsi les pans l'un à l'au tre et en constituant des positionneurs pour les pots. In other words, the cut blank comprises two end panels or panels, one of which has through openings, the other has pre-cut retaining tabs, which have a central part and hinged hinged fins on their sides. opposite, the central part being of dimensions capable of passing through the opening of the first panel, so that after having crossed the corresponding opening, the fins move apart under the effect of the elasticity of the material, thus locking the sides to one another and constituting positioners for the pots.

Le flan découpé peut être réalisé dans différentes dimensions, pour contenir une couche de pots, ou pour contenir deux ou plus de deux couches de pots superposées, avec interposition d'un ou de plusieurs éléments intermédiaires munis d'autres languettes qui possèdent un rainurage curviligne ou de forme mixte, de manière à présenter une certaine élasticité. The cut blank can be produced in different dimensions, to contain a layer of pots, or to contain two or more of two layers of superimposed pots, with the interposition of one or more intermediate elements provided with other tabs which have a curvilinear grooving or of mixed form, so as to have a certain elasticity.

Le nouveau flan découpé ne demande qu'une quantité réduite de matière en feuille ; il n'exige aucun collage (bien qu'il puisse aussi être encollé si on le désire) et il peut être assemblé par des opérations très simples à l'aide de machines automatiques. En outre, les languettes constituent une sorte de sceau de garantie, en ce sens qu'il n'est pas possible, ou du moins pas facile, d'extraire un pot sans violer les languettes de fa çon visible. The new cut blank requires only a reduced amount of sheet material; it requires no gluing (although it can also be glued if desired) and it can be assembled by very simple operations using automatic machines. In addition, the tongues constitute a sort of guarantee seal, in the sense that it is not possible, or at least not easy, to extract a jar without violating the tongues in a visible manner.

la figure 6 est une vue en plan d'un autre flan découpé similaire à celui de la figure 1, pour le conditionnement d'une unique couche de pots
la figure 7 montre une unique couche de pots conditionnée à l'aide du flan découpé de la figure 6
Le flan découpé représenté sur la figure 1 est désigné dans son ensemble par la référence 10. I1 a la forme d'une bande qui comprend un panneau central 12 sur les côtés opposés duquel s'étendent des panneaux ou pans latéraux 14 et 16 ; au-delà de ceux-ci s'étendent des panneaux ou pans d'extrémité respectifs 18, 20. Le panneau 14 s'articule au panneau 12 le long d'une ligne de pliage, entrecoupée d'ouvertures 23 en arc de cercle, connues en soi.
The figures of the appended drawing, given by way of example, will make it clear how the invention can be implemented. On this drawing,
Figure 1 is a plan view of a first embodiment of the cut blank, shown laid flat

Figure 4 is a detail cut from the packaging of Figure 3
Figure 5 is another detail shown cut from the packaging of Figure 3
Figure 6 is a plan view of another cut blank similar to that of Figure 1, for packaging a single layer of pots
Figure 7 shows a single layer of pots packaged using the blank cut from Figure 6
The cut blank shown in Figure 1 is designated as a whole by the reference 10. I1 has the shape of a strip which comprises a central panel 12 on the opposite sides of which extend panels or side panels 14 and 16; beyond these extend respective panels or end panels 18, 20. The panel 14 is articulated to the panel 12 along a fold line, interspersed with openings 23 in an arc of a circle, known per se.

De même, le panneau 16 s'articule au panneau 12 le long d'une ligne de pliage 24 (parallèle à la ligne 22) entrecoupée d'ouvertures 25 en arc de cercle. Similarly, the panel 16 is articulated to the panel 12 along a fold line 24 (parallel to the line 22) interspersed with openings 25 in an arc.

La dimension des panneaux 14 et 16 est liée à la hauteur des pots à conditionner et peut être à peu près égale à cette hauteur ou à un multiple de celleci ; dans l'exemple de la figure, elle est à peu près égale au double de cette hauteur. The size of the panels 14 and 16 is linked to the height of the pots to be packaged and can be roughly equal to this height or to a multiple thereof; in the example in the figure, it is approximately equal to twice this height.

Le panneau 18 s'articule au panneau 14 le long d'une ligne de pliage 26 entrecoupée d'ouvertures 27. Le panneau 20 s'articule au panneau 16 le long d'une ligne de pliage 28 entrecoupée d'ouvertures 29, symétriques des ouvertures 27 et de forme connue en soi (pour s'adapter à la base des pots). The panel 18 is articulated on the panel 14 along a fold line 26 interspersed with openings 27. The panel 20 is articulated on the panel 16 along a fold line 28 interspersed with openings 29, symmetrical of the openings 27 and of shape known per se (to adapt to the base of the pots).

Le panneau de base 18 présente des ouvertures traversantes 30 alignées selon une ligne qui, lorsque le flan découpé esr monté, coïncide avec la médiane de la base du flan. The base panel 18 has through openings 30 aligned along a line which, when the cut blank is mounted, coincides with the median of the base of the blank.

Les ouvertures sont au nombre de deux pour chaque paire de pots et ont de préférence une forme quadrangulaire. Cette forme pourrait être un rectangle mais elle est de préférence une forme trapézoïdale comme représenté sur les figures ; les trapèzes sont de préférence disposés en alternance le long de la médiane précitée. The openings are two in number for each pair of pots and preferably have a quadrangular shape. This shape could be a rectangle but it is preferably a trapezoidal shape as shown in the figures; the trapezoids are preferably arranged alternately along the aforementioned median.

Le second panneau de base 20 présente des languettes 32 qui y sont prédécoupées et qui sont alignées et opposées face à face deux à deux ; chaque languette a un côté rainuré 33 réuni au reste du panneau et qui joue le rôle de charnière, tandis que les autres lignes de son contour sont découpées et elle est rainurée le long de deux lignes 34, de préférence parallèles entre elles, pour former deux ailettes 36 sur les deux côtés d'un corps central 35. Chaque ailette 36 est définie par une ligne courbe 36' et par une ligne de base généralement rectiligne 36". La distance entre les languettes est fonction des dimensions des pots à conditionner. The second base panel 20 has tongues 32 which are precut therein and which are aligned and opposite face to face in pairs; each tongue has a grooved side 33 joined to the rest of the panel and which acts as a hinge, while the other lines of its outline are cut out and it is grooved along two lines 34, preferably parallel to each other, to form two fins 36 on the two sides of a central body 35. Each fin 36 is defined by a curved line 36 'and by a generally straight base line 36 ". The distance between the tongues depends on the dimensions of the pots to be packaged.

Sur la figure 2, on a représenté un élément intermédiaire 40, constitué par un panneau central 42 et deux pans latéraux 44, 46 qui sont articulés au panneau 42 le long de lignes de pliage parallèles 48 et 50 dont chacune est entrecoupée de découpures 52. Le panneau central 42 présente des ailettes de retenue 54 disposées par paires et définies sur trois côtés par des lignes de découpage en U, tandis que, sur le quatrième côté, elles sont définies chacune par une ligne de pliage 56 incurvée en arc ou de forme mixte, de manière à permettre de plier les ailettes tout en leur conservant une certaine force de rappel élastique vers la position de fermeture. In FIG. 2, an intermediate element 40 is shown, constituted by a central panel 42 and two side panels 44, 46 which are articulated to the panel 42 along parallel fold lines 48 and 50 each of which is interspersed with cutouts 52. The central panel 42 has retaining fins 54 arranged in pairs and defined on three sides by U-shaped cutting lines, while, on the fourth side, they are each defined by a fold line 56 curved in an arc or in shape mixed, so as to allow the fins to be folded while retaining a certain elastic return force towards the closed position.

En utilisation, on dispose le flan 40 (figure 4) sur une première série de six pots V rangés en deux files juxtaposées, de manière à bloquer les bords supérieurs dans les découpures 52, d'une façon connue. Sur le flan 40, on insère latéralement les bases des six pots d'une série supérieure de pots, après avoir redres sé les ailettes 54 ; chaque paire d'ailettes 54 bloque les bases de deux pots sur deux côtés et chaque ailette 54 reste pressée contre les pots par l'élasticité induite par la ligne de rainurage courbe 56. In use, the blank 40 (FIG. 4) is placed on a first series of six pots V arranged in two juxtaposed rows, so as to block the upper edges in the cutouts 52, in a known manner. On the blank 40, the bases of the six pots of a higher series of pots are inserted laterally, after having straightened the fins 54; each pair of fins 54 blocks the bases of two pots on two sides and each fin 54 remains pressed against the pots by the elasticity induced by the curved grooving line 56.

Naturellement, le nombre de pots indiqué ne constitue qu'un exemple, et le flan peut aussi être utilisé pour conditionner une, deux, trois, quatre, etc. Naturally, the number of pots indicated is only an example, and the blank can also be used to condition one, two, three, four, etc.

paires de pots.pairs of pots.

Sur les douze pots ainsi assemblés, on pose la bande 10. Le panneau supérieur 12 s'appuie sur les couvercles des pots supérieurs et bloque les bords de ces pots dans les ouvertures 23 et 25, d'une façon connue en soi. On dispose les panneaux latéraux le long des côtés des pots. On superpose les panneaux de base 18 et 20, en plaçant le panneau 18 sur le panneau 20 ; les ouvertures et les ailettes prennent de cette façon des positions sensiblement coïncidentes. Ensuite, on enfile chaque languette 32, à l'aide d'un poinçon ou manuellement, à travers l'ouverture 30 respective, dont les parois inclinées servent d'entrée. Chaque languette 32 traverse facilement l'ouverture respective parce que les ailettes 36 se replient autour des lignes 34.Dès que l'ouverture 30 est franchie, les ailettes 36 de la languette respective s'écartent sous l'effet de l'élasticité de la matière, en assemblant ainsi les panneaux 28 et 20 l'un à l'autre par une liaison solide. Cet assemblage est solide et stable et rend superflue l'application de colle, cette application pouvant cependant être réalisée si on le désire. On the twelve pots thus assembled, the strip 10 is placed. The upper panel 12 rests on the covers of the upper pots and blocks the edges of these pots in the openings 23 and 25, in a manner known per se. The side panels are placed along the sides of the pots. The base panels 18 and 20 are superimposed, placing the panel 18 on the panel 20; the openings and the fins in this way assume substantially coincident positions. Then, each tongue 32 is threaded, using a punch or manually, through the respective opening 30, the inclined walls of which serve as an inlet. Each tongue 32 easily crosses the respective opening because the fins 36 fold around the lines 34. As soon as the opening 30 is crossed, the fins 36 of the respective tongue move apart under the effect of the elasticity of the material, thus assembling the panels 28 and 20 to each other by a solid connection. This assembly is solid and stable and makes the application of glue superfluous, this application can however be carried out if desired.

En outre, chaque paire de languettes bloque deux pots V juxtaposés entre les ailettes respectives. In addition, each pair of tabs blocks two jars V juxtaposed between the respective fins.

Sur les figures 6 et 7, on a représenté un flan découpé 100 selon l'invention, dimensionné pour conditionner une seule couche de pots. Sur ces figures, les éléments identiques aux éléments de la figure 1 portent les mêmes numéros de référence et ne seront pas décrits en détail. In Figures 6 and 7, there is shown a cut blank 100 according to the invention, dimensioned to condition a single layer of pots. In these figures, the elements identical to the elements of Figure 1 have the same reference numbers and will not be described in detail.

I1 convient de remarquer que, dans ce cas, les panneaux 14, 16 ont une hauteur qui correspond sensiblement à la hauteur d'un seul pot, et que l'élément intermédiaire 40 est absent. I1 should be noted that, in this case, the panels 14, 16 have a height which corresponds substantially to the height of a single pot, and that the intermediate element 40 is absent.

I1 va de soi que des modifications pourront être apportées par l'homme de l'art au dispositif qui vient d'être décrit à titre d'exemple non limitatif sans pour celà sortir du domaine de l'invention.  It goes without saying that modifications may be made by those skilled in the art to the device which has just been described by way of nonlimiting example without thereby departing from the scope of the invention.
