Description

La présente invention concerne un emballage en carton ou matière analogue pour une pluralité d'objets, une ébauche pour la réalisation par pliage dudit emballage et un procédé de fabrication de ladite ébauche.The present invention relates to a cardboard or similar material packaging for a plurality of objects, a blank for making by folding said packaging and a method of manufacturing said blank.

Le conditionnement d'une pluralité d'objets, identiques ou différents, dans un emballage commun pose un problème d'immobilisation desdits objets dans l'emballage lorsque ceux-ci n'occupent pas tout l'espace disponible. A cet effet, il est actuellement habituel de remplir les vides, demeurant dans l'emballage après introduction desdits objets, par une matière de remplissage, telle que de la fibre cellulosique, du papier, des produits cellulaires, etc... Chacune de ces matières présentent des inconvénients particuliers liés à leur nature spécifique, et, de plus, l'inconvénient commun qu'il est nécessaire de les retirer après réception. Pour éviter ces inconvénients, on a imaginé d'utiliser deux feuilles de matière synthétique rétractable recouvrant lesdits objets, dont des premières extrémités sont fixées à l'intérieur de l'emballage, et les secondes extrémités libres se chevauchant sont fixées l'une à l'autre, puis chauffées pour les faire se rétracter sur lesdits objets.The packaging of a plurality of objects, identical or different, in a common packaging poses a problem of immobilization of said objects in the packaging when they do not occupy all the available space. For this purpose, it is currently customary to fill the voids, remaining in the packaging after introduction of said objects, with a filling material, such as cellulose fiber, paper, cellular products, etc. Each of these materials have particular drawbacks related to their specific nature, and, in addition, the common drawback that it is necessary to remove them after receipt. To avoid these drawbacks, it has been imagined to use two sheets of shrinkable synthetic material covering said objects, the first ends of which are fixed inside the packaging, and the second overlapping free ends are fixed one to the other. 'other, then heated to retract them on said objects.

Cependant, une simple fixation desdites feuilles, notamment par collage, à l'intérieur de l'emballage n'est souvent pas suffisamment résistante lorsque l'emballage est soumis à différentes contraintes en cours de manipulation, ce qui a pour conséquence une rupture des liaisons des feuilles à l'emballage et le déversement du contenu de ce dernier, ou tout au moins la non immobilisation des objets dans l'emballage. Pour éviter ce risque, il existe un certain nombre d'artifices permettant de renforcer la fixation desdites feuilles. Néanmoins, ceux-ci sont généralement complexes, en augmentant ainsi le coût de fabrication de l'emballage.However, a simple fixing of said sheets, in particular by gluing, inside the packaging is often not sufficiently resistant when the packaging is subjected to various stresses during handling, which results in rupture of the connections. leaves to the packaging and the spillage of the contents thereof, or at least the non-immobilization of objects in the packaging. To avoid this risk, there are a number of devices for strengthening the attachment of said sheets. However, these are generally complex, thereby increasing the cost of manufacturing the package.

La présente invention a pour but d'éviter ces inconvénients, et concerne un emballage dans lequel la fixation des feuilles de matière synthétique rétractable est assurée quelles que soient les contraintes auxquelles l'emballage peut être soumis en cours de manipulation, et cela de façon simple, sans augmenter le coût de l'emballage.The present invention aims to avoid these drawbacks, and relates to a packaging in which the fixing of the shrinkable plastic sheets is ensured regardless of the constraints to which the packaging can be subjected during handling, and this in a simple manner , without increasing the cost of packaging.

A cet effet, l'emballage en carton ou matière analogue pour une pluralité d'objets, comportant un corps comprenant une ceinture latérale et un fond, définissant un volume de réception desdits objets, et au moins une feuille de matière synthétique rétractable fixée audit corps et destinée à recouvrir ladite pluralité d'objets et à immobiliser celle-ci dans ledit volume par rétraction de ladite feuille, est remarquable, selon l'invention, en ce que ledit fond est constitué d'une pluralité de volets reliés, chacun, par une ligne de pliage à ladite ceinture latérale le long du bord longitudinal inférieur de celle-ci, et en ce que ladite feuille est fixée à au moins un desdits volets de fond recouvert, au moins partiellement, par au moins un autre desdits volets de fond, de façon à coincer ladite feuille entre lesdits volets.To this end, the packaging made of cardboard or similar material for a plurality of objects, comprising a body comprising a lateral belt and a bottom, defining a volume for receiving said objects, and at least one sheet of retractable synthetic material fixed to said body. and intended to cover said plurality of objects and to immobilize it in said volume by retraction of said sheet, is remarkable, according to the invention, in that said bottom consists of a plurality of flaps each connected by a fold line at said lateral belt along the lower longitudinal edge thereof, and in that said sheet is fixed to at least one of said bottom flaps covered, at least partially, by at least one other of said bottom flaps , so as to wedge said sheet between said flaps.

Ainsi, la feuille de matière synthétique rétractable est fermement maintenue entre lesdits volets, d'autant plus que le poids des objets contenus dans l'emballage participe à ce solide maintien de la feuille, et cela sans recourir à des artifices complexes et, en définitive, coûteux, comme cela était le cas jusqu'à présent.Thus, the sheet of retractable synthetic material is firmly held between said flaps, especially since the weight of the objects contained in the packaging contributes to this solid holding of the sheet, and this without resorting to complex devices and, ultimately , expensive, as was the case until now.

Il est envisageable que ladite feuille soit fixée à la face externe d'un volet, mais, de préférence, ladite feuille est fixée à la face interne d'au moins un desdits volets de fond.It is conceivable that said sheet is fixed to the external face of a flap, but, preferably, said sheet is fixed to the internal face of at least one of said bottom flaps.

Avantageusement, ladite feuille est fixée parallèlement au bord longitudinal de ladite ceinture latérale.Advantageously, said sheet is fixed parallel to the longitudinal edge of said lateral belt.

En particulier, ledit volet de fond auquel est fixé ladite feuille peut être recouvert par au moins un des volets adjacents à celui-ci.In particular, said bottom flap to which said sheet is fixed may be covered by at least one of the flaps adjacent to it.

Dans le cas où l'emballage comporte deuxdites feuilles de matière synthétique rétractable dont des premières extrémités sont fixées audit corps et dont les secondes extrémités libres se chevauchant sont destinées à être fixées l'une à l'autre, avant rétraction desdites feuilles sur lesdits objets, selon l'invention, ledit fond est constitué de deux paires de volets opposés, et les premières extrémités desdites feuilles sont fixées, chacune, à un volet d'une première paire de volets de fond, la seconde paire de volets de fond recouvrant les volets de ladite première paire de façon à coincer lesdites premières extrémités desdites feuilles entre lesdites première et seconde paires de volets de fond.In the case where the packaging comprises two said sheets of retractable synthetic material, the first ends of which are fixed to said body and the second overlapping free ends of which are intended to be fixed to each other, before retraction of said sheets on said objects , according to the invention, said bottom consists of two pairs of opposite flaps, and the first ends of said sheets are each fixed to a flap of a first pair of bottom flaps, the second pair of bottom flaps covering the flaps of said first pair so as to wedge said first ends of said sheets between said first and second pairs of bottom flaps.

Par ailleurs, il est avantageux que chaque feuille soit fixée au voisinage du bord longitudinal inférieur de ladite ceinture latérale, et/ou que ladite feuille soit fixée par collage.Furthermore, it is advantageous that each sheet is fixed in the vicinity of the lower longitudinal edge of said lateral belt, and / or that said sheet is fixed by gluing.

En outre, l'invention concerne une ébauche pour la réalisation par pliage de l'emballage précédemment défini, comportant, selon l'invention :

  • un flan en carton ou matière analogue sous forme d'une bande allongée présentant une première partie longitudinale, séparée par des lignes de pliage transversales en une pluralité de portions adjacentes dont chacune est destinée à former une face de la ceinture latérale de l'emballage et une seconde partie longitudinale, reliée à ladite première partie par une ligne de pliage et subdivisée par des lignes de découpe en une pluralité de volets adjacents destinés à former le fond dudit emballage, et
  • au moins une feuille de matière synthétique rétractable fixée à au moins un desdits volets.
In addition, the invention relates to a blank for making the previously defined packaging by folding, comprising, according to the invention:
  • a blank of cardboard or similar material in the form of an elongated strip having a first longitudinal part, separated by transverse fold lines into a plurality of adjacent portions, each of which is intended to form one face of the lateral belt of the package and a second longitudinal part, connected to said first part by a fold line and subdivided by cut lines into a plurality of adjacent flaps intended to form the bottom of said package, and
  • at least one sheet of retractable synthetic material attached to at least one of said flaps.

De préférence, ladite feuille est fixée parallèlement à la ligne de pliage séparant lesdites première et seconde parties, et s'étend vers la portion, prolongeant le volet auquel est fixée ladite feuille, de ladite première partie.Preferably, said sheet is fixed parallel to the fold line separating said first and second parts, and extends towards the portion, extending the flap to which said sheet is fixed, from said first part.

En particulier, ledit flan peut comporter quatre desdites portions, à chacune desquelles correspond un volet de fond, et deuxdites feuilles de matière synthétique rétractable sont prévues, en étant fixées à des premier et second volets respectifs, séparés par un troisième volet.In particular, said blank may include four of said portions, to each of which corresponds a bottom flap, and two said sheets of retractable synthetic material are provided, being fixed to respective first and second flaps, separated by a third flap.

Avantageusement, chaque feuille est fixée au volet respectif au voisinage de la ligne de pliage séparant ledit volet de la portion correspondante, et/ou chaque feuille est fixée au volet respectif par collage.Advantageously, each sheet is fixed to the respective flap in the vicinity of the fold line separating said flap from the corresponding portion, and / or each sheet is fixed to the respective flap by gluing.

Par ailleurs, ledit flan peut comporter un rabat prolongeant une extrémité de ladite première partie longitudinale.Furthermore, said blank may include a flap extending one end of said first longitudinal part.

L'invention se rapporte également à un procédé de fabrication de l' ébauche décrite ci-dessus, dans lequel, selon l'invention :

  • a) on découpe un flan en carton ou matière analogue sous forme d'une bande allongée présentant une première partie longitudinale, séparée par des lignes de pliage transversales en une pluralité de portions adjacentes dont chacune est destinée à former une face de la ceinture latérale de l'emballage, et une seconde partie longitudinale, reliée à ladite première partie par une ligne de pliage et subdivisée par des lignes de découpe en une pluralité de volets adjacents destinés à former le fond de l'emballage, et
  • b) on fixe au moins une feuille de matière synthétique rétractable à au moins un desdits volets.
The invention also relates to a process for manufacturing the blank described above, in which, according to the invention:
  • a) a blank of cardboard or similar material is cut in the form of an elongated strip having a first longitudinal part, separated by transverse fold lines into a plurality of adjacent portions, each of which is intended to form one face of the lateral belt of the packaging, and a second longitudinal part, connected to said first part by a fold line and subdivided by cut lines into a plurality of adjacent flaps intended to form the bottom of the package, and
  • b) at least one shrinkable plastic sheet is attached to at least one of said flaps.

Avantageusement, on fixe ladite feuille parallèlement à la ligne de pliage séparant lesdites première et seconde parties, ladite feuille s'étendant vers la portion, prolongeant ledit volet, de ladite première partie.Advantageously, said sheet is fixed parallel to the fold line separating said first and second parts, said sheet extending towards the portion, extending said flap, of said first part.

Dans un cas particulier :

  • on sépare ladite première partie longitudinale en quatre portions adjacentes à chacune desquelles correspond un volet de ladite seconde partie longitudinale, et
  • on fixe deuxdites feuilles de matière synthétique rétractable à des premier et second volets respectifs, séparés par un troisième volet.
In a particular case:
  • separating said first longitudinal part into four adjacent portions, each of which corresponds to a flap of said second longitudinal part, and
  • two said sheets of retractable synthetic material are fixed to respective first and second flaps, separated by a third flap.

De préférence, on déroule chaque feuille d'une bobine et on la coupe à la longueur souhaitée.Preferably, each sheet is unwound from a reel and cut to the desired length.

En particulier, on peut fixer chaque feuille au volet respectif au voisinage de la ligne de pliage séparant ledit volet de la portion correspondante et/ou fixer chaque feuille au volet respectif par collage.In particular, it is possible to fix each sheet to the respective flap in the vicinity of the fold line separating said flap from the corresponding portion and / or to fix each sheet to the respective flap by gluing.

Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée.The figures of the appended drawing will make it clear how the invention can be implemented.

La figure 1 est une vue en plan d'un exemple de réalisation de l'ébauche à partir de laquelle est réalisé l'emballage selon l'invention.Figure 1 is a plan view of an exemplary embodiment of the blank from which is made the packaging according to the invention.

La figure 2 est une vue en perspective, avec arrachement, de l'emballage réalisé à partir de l' ébauche de la figure 1.FIG. 2 is a perspective view, with parts broken away, of the packaging produced from the blank of FIG. 1.

La figure 3 montre, en perspective, l'emballage de la figure 2, dans lequel des objets ont été placés.Figure 3 shows, in perspective, the packaging of Figure 2, in which objects have been placed.

En se référant à la figure 1, l'emballage de l'invention est réalisé à partir d'une ébauche 1 comportant un flan 2 en carton ou matière analogue sous forme d'une bande allongée présentant une première partie longitudinale 3, séparée par des lignes de pliage transversales 4a,4b et 4c en quatre portions adjacentes 5a,5b,5c et 5d, dont chacune est destinée à former une face de la ceinture latérale de l'emballage. Le flan 2 présente de plus une seconde partie longitudinale 6, reliée à la première partie 3 par une ligne de pliage 7 et subdivisée par des lignes de découpe 8a,8b et 8c en quatre volets 9a,9b,9c et 9d destinés à former le fond de l'emballage. De plus, le flan 2 comporte un rabat 10 prolongeant une extrémité de la première partie longitudinale 3, et destiné à fixer ensemble les deux extrémités de la ceinture latérale de l'emballage.Referring to Figure 1, the packaging of the invention is made from a blank 1 comprising a blank 2 of cardboard or similar material in the form of an elongated strip having a first longitudinal part 3, separated by transverse fold lines 4a, 4b and 4c into four adjacent portions 5a, 5b, 5c and 5d, each of which is intended to form one face of the lateral belt of the package. The blank 2 also has a second longitudinal part 6, connected to the first part 3 by a fold line 7 and subdivided by cut lines 8a, 8b and 8c into four sections 9a, 9b, 9c and 9d intended to form the bottom of the package. In addition, the blank 2 has a flap 10 extending one end of the first longitudinal part 3, and intended to fix the two ends of the lateral belt of the packaging together.

Par ailleurs, deux feuilles de matière synthétique rétractable 11a,11b sont fixées, à de premières extrémités 12a,12b de celles-ci, à deux volets respectifs 9a,9c, séparés par un troisième volet 9b, c'est-à-dire à deux volets qui seront opposés l'un à l'autre lorsque l'emballage sera formé. On pourrait donc aussi bien prévoir de fixer les feuilles 11a,11b aux volets 9b,9d, respectivement. Ladite première extrémité 12a ou 12b est plus précisément fixée au volet correspondant 9a,9c parallèlement à la ligne de pliage 7, avantageusement au voisinage de cette dernière, par exemple par collage, ce qui est symbolisé, sur la figure 1, par les lignes en traits interrompus 13a,13b. Bien entendu, chaque feuille pourrait être également collée à un niveau quelconque du volet, ou même sur l'ensemble de celui-ci.Furthermore, two sheets of retractable synthetic material 11a, 11b are fixed, at first ends 12a, 12b thereof, to two respective flaps 9a, 9c, separated by a third flap 9b, that is to say to two flaps which will be opposite to each other when the packaging is formed. We could therefore also plan to fix the sheets 11a, 11b to the flaps 9b, 9d, respectively. Said first end 12a or 12b is more precisely fixed to the corresponding flap 9a, 9c parallel to the fold line 7, advantageously in the vicinity of the latter, for example by gluing, which is symbolized, in FIG. 1, by the lines in broken lines 13a, 13b. Of course, each sheet could also be glued to any level of the shutter, or even on the whole of it.

Pour obtenir cette ébauche, on découpe tout d'abord le flan 2 de façon à obtenir la configuration décrite en référence à la figure 1, puis, après application des lignes de colle 13a,13b, on fixe lesdites feuilles de matière synthétique rétractable 11a, 11b, qui peuvent avantageusement provenir, chacune, d'une bobine de feuille et être découpées à la longueur appropriée.To obtain this blank, the blank 2 is first cut so as to obtain the configuration described with reference to FIG. 1, then, after application of the glue lines 13a, 13b, said sheets of retractable synthetic material 11a are fixed, 11b, which can advantageously each come from a sheet reel and be cut to the appropriate length.

En se référant maintenant à la figure 2, on voit que l'emballage 100 selon l'invention est obtenu par pliage de l'ébauche 1 de la figure 1. Plus précisément, le fond 101 de l'emballage 100 est obtenu en repliant les volets 9a,9c et 9b,9d, deux à deux, l'un vers l'autre, de façon que les volets 9a,9c, auxquels sont fixées les feuilles 11a,11b, soient recouverts par les volets 9b,9d en coinçant ainsi les extrémités 12a,12b desdites feuilles 11a,11b entre le volet 9a ou 9c et les deux volets 9b,9d adjacents à celui-ci. Comme déjà indiqué, cela permet de maintenir fermement la feuille entre des volets de fond, sans risque d'arrachement de celle-ci en cours de manipulation de l'emballage.Referring now to Figure 2, we see that the package 100 according to the invention is obtained by folding the blank 1 of Figure 1. More specifically, the bottom 101 of the package 100 is obtained by folding the flaps 9a, 9c and 9b, 9d, two by two, one towards the other, so that the flaps 9a, 9c, to which the sheets 11a, 11b are fixed, are covered by the flaps 9b, 9d thereby wedging the ends 12a, 12b of said sheets 11a, 11b between the flap 9a or 9c and the two flaps 9b, 9d adjacent to it. As already indicated, this makes it possible to firmly hold the sheet between bottom flaps, without the risk of tearing it off during handling of the packaging.

En même temps que l'on replie les volets de fond 9a-9d, les portions 5a-5d du flan 2 sont repliées de façon à former la ceinture latérale 102 de l'emballage 100, dont les deux extrémités seront fixées l'une à l'autre à l'aide du rabat 10.At the same time as the bottom flaps 9a-9d are folded back, the portions 5a-5d of the blank 2 are folded so as to form the lateral belt 102 of the package 100, the two ends of which will be fixed one to the other. the other using the flap 10.

Comme montré sur la figure 2, les feuilles 11a,11b s'étendent, à partir du fond 101, chacune le long d'une face interne de la ceinture latérale 102 et au-delà de celle-ci de façon que leurs extrémités libres 14a,14b puissent se chevaucher, et être fixées l'une à l'autre, lorsque lesdites feuilles 11a,11b recouvriront les objets 103 mis en place dans l'emballage 100 (figure 3). La rétraction des feuilles 11a,11b permettra de maintenir solidement en place les objets 103 dans l'emballage 100, le poids des objets 103 participant de plus au maintien de chaque feuille, coincée entre des volets de fond.As shown in FIG. 2, the sheets 11a, 11b extend, starting from the bottom 101, each along an internal face of the lateral belt 102 and beyond it so that their free ends 14a , 14b can overlap, and be fixed to each other, when said sheets 11a, 11b will cover the objects 103 placed in the package 100 (Figure 3). The retraction of the sheets 11a, 11b will make it possible to securely hold the objects 103 in the packaging 100, the weight of the objects 103 further participating in the maintenance of each sheet, wedged between bottom flaps.
