Abstract

The package comprises a rectangular or square base (2) edged by two longitudinal sides (3, 4) and by two transverse sides (5, 6) each of which is connected to the said base (2) by a folding line (7, 8, 9 or 10), each longitudinal side (3, 4) being extended at each of its ends by a flap (11.5, 11.6, 12.5 or 12.6) articulated about a folding line (13, 14, 15 or 16) orthogonal to the one (7 or 8) connecting the corresponding longitudinal side (3 or 4) to the said base (2). According to the invention, this package is characterised in that among the two flaps (11.5, 12.5 or 11.6, 12.6) associated with a transverse side (5 or 6), one of them (11.5, 11.6) has a length greater than half of the length of the corresponding transverse side (5, 6) and comprises a protrusion (41) which alone forms a stacking stud. <IMAGE>

Description

La présente invention concerne un emballage de carton ou analogue, en forme de boîte ouverte.The present invention relates to a cardboard or similar packaging, in the form of an open box.

On sait que de nombreux emballages de ce genre sont uti­lisés pour le conditionnement, le transport, le stockage et pour l'exposition en vue de la vente d'objets tels que des fruits, des légumes, des fromages etc... Ces embal­lages comprennent généralement un fond rectangulaire ou carré, bordé par deux côtés longitudinaux et par deux côtés transversaux, dont chacun d'eux est relié audit fond par une ligne de pliage. Chaque côté longitudinal est prolongé à chacune de ses extrémités par un volet articulé autour d'une ligne de pliage orthogonale à celle reliant ledit côté longitudinal audit fond et lesdits volets sont solidarisés desdits côtés transversaux, par exemple par collage.It is known that many such packages are used for packaging, transport, storage and for display for the sale of objects such as fruits, vegetables, cheeses, etc. These packages include generally a rectangular or square bottom, bordered by two longitudinal sides and by two transverse sides, each of which is connected to said bottom by a fold line. Each longitudinal side is extended at each of its ends by a flap articulated around a fold line orthogonal to that connecting said longitudinal side to said bottom and said flaps are secured to said transverse sides, for example by gluing.

Afin de pouvoir gerber de tels emballages, on prévoit dans le fond de chacun de ceux-ci, généralement au voisinage du milieu des lignes de pliage reliant lesdits côtés trans­versaux audit fond, des échancrures pour l'introduction de tétons de gerbage portés par l'emballage identique, disposé immédiatement en dessous.In order to be able to stack such packages, provision is made in the bottom of each of these, generally in the vicinity of the middle of the fold lines connecting said transverse sides to said bottom, notches for the introduction of stacking pins carried by the identical packaging, placed immediately below.

Dans les emballages connus de ce type, les quatre volets sont identiques et chacun d'eux comporte une excroissance, qui, associée à l'excroissance d'un autre volet, forme un tel téton de gerbage. Du fait des tolérances de fabrication, l'association de deux excroissances pour former un seul téton de gerbage soulève des difficultés, car il est prati­quement impossible de donne audit téton de gerbage une dimension transversale constante. Il en résulte un mauvais centrage des emballages gerbés. Il peut même en résulter une impossibilité de gerbage, si le téton présente une dimension transversale grande l'empêchant de pénètrer dans l'échancrure coopérante.In known packages of this type, the four flaps are identical and each of them has a protuberance, which, associated with the protrusion of another flap, forms such a stacking stud. Due to manufacturing tolerances, the association of two protuberances to form a single stacking nipple raises difficulties, since it is practically impossible to give said stacking nipple a constant transverse dimension. This results in poor centering of stacked packaging. It may even result in an impossibility of stacking, if the stud has a large transverse dimension preventing it from entering the cooperating notch.

De plus, lesdites excroissances sont à l'origine de chutes de matière lors de la fabrication des flans desdits embal­lages.In addition, said protuberances are the source of material falls during the manufacture of the blanks of said packages.

La présente invention a pour objet de remédier à ces incon­vénients.The object of the present invention is to remedy these drawbacks.

A cette fin, selon l'invention, l'emballage de carton ou analogue en forme de boîte ouverte comprenant un fond rec­tangulaire ou carré, bordé par deux côtés longitudinaux et par deux côtés transversaux, dont chacun d'eux est relié audit fond par une ligne de pliage, chaque côté longitu­dinal étant prolingé à chacune de ses extrémités, par un volet articulé autour d'une ligne de pliage orthogonale à celle reliant le côté longitudinal correspondant audit fond, et ledit fond comportant au voisinage du milieu des lignes de pliage reliant lesdits côtés transversaux audit fond des échancrures pour l'introduction de tétons de gerbage d'un emballage identique sur lequel repose ledit emballage, est remarquable en ce que, parmi les deux volets associés à un côté transversal, l'un d'eux a une longueur supérieure à la moitié de la longueur du côté transversal correspondant et comporte une excroisance qui, à elle seule, forme un tel téton de gerbage.To this end, according to the invention, the packaging of cardboard or the like in the form of an open box comprising a rectangular or square bottom, bordered by two longitudinal sides and by two transverse sides, each of which is connected to said bottom by a fold line, each longitudinal side being extended at each of its ends, by a flap articulated around a fold line orthogonal to that connecting the longitudinal side corresponding to said bottom, and said bottom comprising in the vicinity of the middle of fold lines connecting said transverse sides to said bottom of the notches for the introduction of stacking pins of an identical package on which said packaging rests, is remarkable in that, among the two flaps associated with a transverse side, one of them has a length greater than half the length of the corresponding transverse side and comprises a protuberance which, in itself, forms such a stacking nipple.

Ainsi, grâce à l'invention, un tel téton de gerbage a une dimension et une position fixes. Il en résulte une grande précision de gerbage.Thus, thanks to the invention, such a stacking nipple has a fixed dimension and position. This results in high stacking precision.

Par ailleurs, afin d'éviter les chutes de matière entre deux flans consécutifs d'emballages, il est avantageux que les deux volets ayant une longueur supérieure à la moitié de la longueur du côté transversal correspondent et compor­tant une telle excroissance, soient disposés d'un même côté de l'axe longitudinal dudit emballage.Furthermore, in order to avoid material falling between two consecutive blanks of packaging, it is advantageous that the two flaps having a length greater than half the length of the transverse side correspond and comprising such a protrusion, are arranged the same side of the longitudinal axis of said packaging.

Afin d'éviter des surépaisseurs, les deux volets ne compor­tant pas ladite excroissance ont, de préférence, une longeur inférieure à la moitié de la longueur du côté transversal correspondant.In order to avoid excess thicknesses, the two flaps not comprising said protuberance preferably have a length less than half the length of the corresponding transverse side.

De plus, pour obtenir un gerbage sans emboitement desdits emballages, il est préférable que lesdits emballages pré­sentent une section transversale trapézoïdale, de façon que leur ouverture soit plus étroite que leur fond.In addition, to obtain stacking without nesting of said packages, it is preferable that said packages have a trapezoidal cross section, so that their opening is narrower than their bottom.

Le flan 1 de carton ondulé, montré par la figure 1, comporte un fond rectangulaire 2, bordé par deux côtés longitudinaux 3 et 4 et par deux côtés transversaux 5 et 6.The blank 1 of corrugated cardboard, shown in FIG. 1, has a rectangular bottom 2, bordered by two longitudinal sides 3 and 4 and by two transverse sides 5 and 6.

Les côtés longitudinaux sont respectivement reliés au fond 2 par des lignes de pliage 9 et 10, parallèles entre elles, mais perpendiculaires aux lignes de pliage 7 et 8.The longitudinal sides are respectively connected to the bottom 2 by fold lines 9 and 10, parallel to each other, but perpendicular to the fold lines 7 and 8.

Par ailleurs, le côté longitudinal 3 est prolongé, à son extrémité voisine du côté transversal 5, par un volet 11.5, et, à son extrémité voisine du côté transversal 6 par un volet 11.6. De même, le côté longitudinal 4 est prolongé par des volets 12.5 et 12.6, respectivement voisins des côtés transversaux 5 et 6. Les volets 11.5, 11.6, 12.5 et 12.6 sont reliés au côté longitudinal 3 ou 4 correspondant par une ligne de pliage respective 13,14,15 ou 16 ortho­gonale à la ligne de pliage 7 ou 8 reliant ce côté longitu­dinal au fond 2. Les lignes de pliage 13 à 16 sont donc parallèles aux lignes de pliage 9 et 10. Elles ne sont pas disposées en prolongement de celles-ci, mais légèrement décalées vers le centre du fond 2 par rapport auxdites lignes de pliage 9 et 10.Furthermore, the longitudinal side 3 is extended, at its end close to the transverse side 5, by a flap 11.5, and, at its end close to the transverse side 6 by a flap 11.6. Similarly, the longitudinal side 4 is extended by flaps 12.5 and 12.6, respectively adjacent to the transverse sides 5 and 6. The flaps 11.5, 11.6, 12.5 and 12.6 are connected to the corresponding longitudinal side 3 or 4 by a respective fold line 13 , 14,15 or 16 orthogonal to the fold line 7 or 8 connecting this longitudinal side to the bottom 2. The fold lines 13 to 16 are therefore parallel to the fold lines 9 and 10. They are not arranged as an extension of those here, but slightly offset towards the center of the bottom 2 relative to said fold lines 9 and 10.

Les volets 11.5, 11.6, 12.5 et 12.6 sont identiques et deux à deux symétriques par rapport à l'axe longitudinal L - L du flan 1. Ils comportent chacun une excroissance 17, diri­gée vers l'extérieur à l'opposé du volet transversal 5 ou 6 correspondant.The flaps 11.5, 11.6, 12.5 and 12.6 are identical and two by two symmetrical with respect to the longitudinal axis L - L of the blank 1. They each have a protrusion 17, directed outwards opposite the transverse flap 5 or 6 correspondent.

Dans le fond 2, au voisinage du milieu des lignes de pliage 9 et 10, sont prévues des échancrures 18, destinées comme on le verra par la suite, à recevoir les saillies de gerbage constituées chacune de deux excroissances 17 symétriques.In the bottom 2, in the vicinity of the middle of the fold lines 9 and 10, there are provided notches 18, intended, as will be seen below, to receive the stacking projections each consisting of two symmetrical protuberances 17.

Dans les côtés transversaux 5 et 6, sont prévues de découpes 19 destinées à servir de poignée. Des découpes correspondantes 20, sont prévues dans les volets 11.5, 11.6, 12.5 et 12.6. Entre chacun de ceux-ci et le volet transversal 5 ou 6 cor­respondant sont prévues des entailles 21 triangulaires, afin de permettre d'obtenir des récipients à section trapézoïdale.In the transverse sides 5 and 6, there are provided cutouts 19 intended to serve as a handle. Corresponding cutouts 20 are provided in sections 11.5, 11.6, 12.5 and 12.6. Between each of these and the corresponding transverse flap 5 or 6 are provided triangular notches 21, in order to allow containers of trapezoidal section to be obtained.

Sur la figure 1, on a représenté de plus ein trait mixte un flan 22 identique et consécutif. On peut ainsi voir qu'à cause des excroissances 17, des chutes de matière 23 sont inévitables entre les flans 1 et 22.In FIG. 1, there is also shown in mixed line an identical and consecutive blank 22. It can thus be seen that because of the protuberances 17, material falls 23 are inevitable between the blanks 1 and 22.

Notamment lorsque l'emballage obtenue à partir des flans 1 et 22 est destiné à contenir des fromages (non repré­sentés), des ouvertures 24 sont prévues dans lesdits flans.In particular when the packaging obtained from the blanks 1 and 22 is intended to contain cheeses (not shown), openings 24 are provided in the said blanks.

La mise en forme des flans 1 et 22, en vue de la réalisation des emballages connus 30 ou 32 illustrés par la figure 2, est explicitée ci-après.The shaping of the blanks 1 and 22, with a view to producing the known packages 30 or 32 illustrated in FIG. 2, is explained below.

Tout d'abord, on plie orthogonalement les côtés longitudi­naux 3 et 4 autour des lignes de pliage 7 et 8, ainsi que les volets 11.5, 11.6, 12.5 et 12.6 autour des lignes de pliage 13 à 16 et les côtés transversaux 5 ou 6 autour des lignes de pliage 9 et 10, de sorte que lesdits volets 11.5, 11.6, 12.5 et 12.6 se trouvent en regard desdits côtés transversaux 5 ou 6. ensuite, lesdits volets sont fixés auxdits côtés transversaux, par exemple, à l'aide d'une matière adhésive . On obtient alors un emballage 30 ou 32 en forme de caisse, tel que représenté schématiquement sur la figure 2. Du fait des entailles triangulaires 21, lesdits emballages 30 ou 32 présentent une section trapézoïdale. Dans cette conformation, les deux échancrures 20 de volets associés 11.5, 12.5 ou 11.6, 12.6, forment une ouverture superposée à la découpe 19 du volet transversal 5 ou 6 correspondant.First, the longitudinal sides 3 and 4 are orthogonally folded around the fold lines 7 and 8, as well as the flaps 11.5, 11.6, 12.5 and 12.6 around the fold lines 13 to 16 and the transverse sides 5 or 6 around fold lines 9 and 10, so that said flaps 11.5, 11.6, 12.5 and 12.6 are located opposite said transverse sides 5 or 6. then said flaps are fixed to said transverse sides, for example using an adhesive material. A package 30 or 32 is then obtained in the form of a box, as shown diagrammatically in FIG. 2. Due to the triangular cuts 21, said packages 30 or 32 have a trapezoidal section. In this configuration, the two notches 20 of associated flaps 11.5, 12.5 or 11.6, 12.6, form an opening superimposed on the cutout 19 of the corresponding transverse flap 5 or 6.

Lors du rapprochement par pliage des paires de volets 11.5, 12.5 et 11.6, 12.6, il se forme dans la partie centrale des côtés transversaux de tels emballages, une saillie 31 pouvant coopérer avec une échancrure 18 du fond d'un autre emballage identique (voir la figure 2). Les emballages 30 et 32 sont donc gerbables.When the pairs of flaps 11.5, 12.5 and 11.6, 12.6 are brought together by folding, there is formed in the central part of the transverse sides of such packages, a projection 31 which can cooperate with a notch 18 in the bottom of another identical package (see Figure 2). The packaging 30 and 32 are therefore stackable.

Cette propriété est accentuée du fait de leur section transversale trapézoïdale, qui a pour conséquence que leur fond est plus large que leur ouverture (voir également la figure 2).This property is accentuated because of their trapezoidal cross section, which has the consequence that their bottom is wider than their opening (see also Figure 2).

Comme le montre clairement la figure 3, dans un tel embal­lage 30 ou 32 obtenu à partir d'un flan connu (1 ou 22), la saillie de gerbage 31 est formée par le rapprochement des deux excroissances 17 d'une paire 11.5 - 12.5 ou 11.6 - 12.6 de volets. Par suite des imprécisions de fabrication, une telle saillie 31 peut alors présenter une largeur 1 variable, qui, éventuellement, peut être trop grande pour que ladite saillie 31 puisse pénétrer dans l'échancrure 18 correspon­dante.As clearly shown in Figure 3, in such a package 30 or 32 obtained from a known blank (1 or 22), the stacking projection 31 is formed by the approximation of the two protrusions 17 of a pair 11.5 - 12.5 or 11.6 - 12.6 of flaps. As a result of manufacturing inaccuracies, such a projection 31 may then have a variable width 1 , which, possibly, may be too large for said projection 31 to be able to penetrate into the corresponding notch 18.

Sur la figure 4, on a représenté un flan 40 conforme à l'invention, permettant d'éviter cet inconvénient, ainsi que la perte de matière 23, montrée par la figure 1.FIG. 4 shows a blank 40 according to the invention, making it possible to avoid this drawback, as well as the loss of material 23, shown in FIG. 1 .

Le flan 40 selon l'invention comporte les mêmes éléments 2 à 10 et 13 à 16, 18, 19, 21 et 24 que le flan 1 de la figure 1. En revanche, les volets 11.5, 11.6, 12.5 et 12.6, ne sont plus deux à deux symétriques. Par exemple, les volets 11.5 et 11.6 sont identiques l'un à l'autre et ont une longueur D supérieure à la moitié de la longueur E du volet transversal 5 ou 6 correspondant. De plus, ces volets 11.5 et 11.6 comportent chacun une excroissance 41 qui, lorsque les volets sont rabattus sur lesdits côtés transversaux 5 ou 6, se trouve en position centrale pour former à elle seule la saillie de gerbage 31 (voir la figure 5). Dans ce cas, les volets 12.5 et 12.6, qui sont également identiques l'un à l'autre, ont une longueur d inférieure à la moitié de la longueur E du volet transversal correspondant.The blank 40 according to the invention comprises the same elements 2 to 10 and 13 to 16, 18, 19, 21 and 24 as the blank 1 of FIG. 1. On the other hand, the flaps 11.5, 11.6, 12.5 and 12.6, are not plus two to two symmetrical. For example, the flaps 11.5 and 11.6 are identical to each other and have a length D greater than half the length E of the corresponding transverse flap 5 or 6. In addition, these flaps 11.5 and 11.6 each have a protrusion 41 which, when the flaps are folded over said transverse sides 5 or 6, is in the central position to form the stacking projection 31 alone (see FIG. 5). In this case, the flaps 12.5 and 12.6, which are also identical to each other, have a length d less than half the length E of the corresponding transverse flap.

Ainsi, chaque saillie ou téton de gerbage 31 présente une largeur fixe (celle de l'excroissance 41) et un position­nement fixe (déterminé par la longueur D des volets 11.5 et 11.6).Thus, each projection or stacking stud 31 has a fixed width (that of the projection 41) and a fixed positioning (determined by the length D of the flaps 11.5 and 11.6).

Par ailleurs, grâce au fait que les volets 11.5 et 11.6 portant les excroissances 41 sont disposés d'un même côté de l'axe longitudinal L-L, il est possible d'éviter la perte de matière 23 se produisant entre deux flans consé­cutifs. Sur la figure 4, on a montré qu'un flan consécutif 45, identique au flan 40, pouvait être disposé de façon immédiatement adjacente à celui-ci et éventuellement , une partie des excroissances 41 du flan 45 peut mordre sur les petits volets 12.5 et 12.6 du flan 40.Furthermore, thanks to the fact that the flaps 11.5 and 11.6 carrying the protuberances 41 are arranged on the same side of the longitudinal axis L-L, it is possible to avoid the loss of material 23 occurring between two consecutive blanks. In FIG. 4, it has been shown that a consecutive blank 45, identical to the blank 40, could be placed immediately adjacent to it and possibly, part of the protrusions 41 of the blank 45 can bite on the small flaps 12.5 and 12.6 of the blank 40.
