Abstract

The plastic bag has lateral bellows (1e,1f) and a bottom. On one of its walls (1a) it has a marking line (2) able to constitute a folding zone to form and delimit the bottom relative to the walls by creating a support base (1g) under the effect of the spacing of the bellows and thereby improve the vertical stability.

Description

L'invention se rattache au secteur technique des sacs d'emballage.The invention relates to the technical sector of packaging bags.

D'une manière générale, les sacs d'emballage sont réalisés, le plus souvent, soit en papier carton, soit en matière synthétique ou plastique. Plus particulièrement, l'invention concerne les sacs d'emballage réalisés en matière synthétique ou plastique.
   Ce type de sac peut être réalisé à partir d'une gaine ou d'un film en matière plastique présentant une extrémité fermée faisant office de fond, tandis que l'autre extrémité opposée, est ouverte en étant notamment susceptible de coopérer avec différents moyens pour être fermée à volonté, d'une manière étanche ou non.
   Par exemple, les bords transversaux fermés du sac considérés à sa partie supérieure, peuvent présenter des lignes de prédécoupe assujetties à tout type de moyen d'arrachement. Après arrachement de la partie supérieure du sac, il n'est plus possible de le refermer.
   On a proposé également d'équiper facialement la partie supérieure du sac au niveau de son bord transversal fermé, d'un moyen apte à créer une ouverture temporaire donnant libre accès à l'intérieur du sac et susceptible d'être refermée et réouverte à volonté.In general, the packaging bags are most often made either of cardboard paper, or of synthetic or plastic material. More particularly, the invention relates to packaging bags made of synthetic or plastic material.
This type of bag can be made from a sheath or a plastic film having a closed end acting as a bottom, while the other opposite end is open, being in particular capable of cooperating with different means for be closed at will, tightly or not.
For example, the closed transverse edges of the bag considered at its upper part, may have precut lines subject to any type of tearing means. After tearing off the upper part of the bag, it is no longer possible to close it.
It has also been proposed to equip the upper part of the bag by the face, at its closed transverse edge, with a means capable of creating a temporary opening giving free access to the interior of the bag and capable of being closed and reopened at will. .

On a également proposé, pour augmenter la capacité interne du sac, tout en améliorant sa stabilité, de former, au moment de sa fabrication, des soufflets latéraux. Ces soufflets latéraux sont formés symétriquement, à partir d'une ligne de pliage, lors de la fabrication des sacs par tout moyen connu et approprié. It has also been proposed, to increase the internal capacity of the bag, while improving its stability, to form, at the time of its manufacture, side bellows. These lateral bellows are formed symmetrically, at from a folding line, when making bags by any means known and appropriate.

Sous un effet de remplissage du sac, les soufflets latéraux sont écartés donnant ainsi du volume à l'ensemble du sac et, indirectement, la formation d'un fond, ce qui devrait permettre de maintenir le sac en position verticale ou sensiblement verticale. Il apparaít toutefois que la formation du fond n'est pas clairement définie et ne constitue pas une embase apte à assurer une parfaite stabilité en position verticale ou sensiblement verticale du sac.Under a bag filling effect, the side bellows are separated thus giving volume to the entire bag and, indirectly, the formation of a bottom, which should keep the bag in position vertical or substantially vertical. It appears however that the formation of bottom is not clearly defined and does not constitute a base suitable for ensure perfect stability in a vertical or substantially vertical position from the bag.

Or, il s'avère que cette mauvaise stabilité, en position verticale du sac, pose de réels problèmes, lors de son conditionnement après remplissage sur une chaíne automatique.However, it turns out that this poor stability, in the vertical position of the bag, poses real problems when packing after filling on an automatic chain.

En effet, après remplissage en automatique des sacs par les produits désirés, les sacs doivent très souvent être transférés vers un autre poste de travail afin de les soumettre à d'autres opérations, telles que le fardelage. En effet, il est particulièrement important que les sacs puissent restés parfaitement stables, lors de leur transport de poste en poste, afin, d'une part, de les soumettre, dans de bonnes conditions, aux opérations choisies et, d'autre part, bien évidemment, d'éviter de renverser de leur contenu.Indeed, after automatic filling of the bags with the products the bags must very often be transferred to another post work in order to subject them to other operations, such as wrapping. In Indeed, it is particularly important that the bags can remain perfectly stable, during their transport from post to post, in order to part, to submit them, under good conditions, to the chosen operations and, on the other hand, of course, to avoid spilling their content.

L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these drawbacks, simple, safe, efficient and rational way.

Le problème que se propose de résoudre l'invention est d'assurer une parfaite stabilité en position verticale, d'un sac d'emballage en matière plastique, en évitant tout risque de renversement lors de son transport sur un convoyeur, par exemple. The problem which the invention proposes to solve is to ensure perfect stability in vertical position, of a material packaging bag plastic, avoiding any risk of overturning when transported on a conveyor, for example.

Pour résoudre un tel problème, il a été conçu et mis au point un sac en matière plastique présentant des agencements pour former des soufflets latéraux et un fond, remarquable en ce qu'il présente, sur au moins l'une de ses parois, une ligne de marquage apte à constituer une zone de pliure déterminée pour former et délimiter le fond par rapport aux parois, en créant une embase d'appui sous l'effet de l'écartement des soufflets, en vue d'améliorer sa stabilité en position verticale.To solve such a problem, it was designed and developed a bag of plastics material having arrangements for forming bellows lateral and a background, remarkable in that it presents, on at least one of its walls, a marking line capable of constituting a fold zone determined to form and delimit the bottom in relation to the walls, creating a support base under the effect of the spacing of the bellows, in view to improve its stability in vertical position.

Pour résoudre le problème posé de réaliser une embase de stabilité, la ligne de marquage est formée parallèlement au fond.To solve the problem of making a stability base, the marking line is formed parallel to the bottom.

Pour résoudre le problème posé d'obtenir une stabilité maximum, la ligne de marquage est située à une distance du fond correspondant sensiblement à la moitié de la largeur des agencements aptes à former les soufflets.To solve the problem of obtaining maximum stability, the marking line is located at a distance from the corresponding background substantially half the width of the arrangements capable of forming the bellows.

Pour améliorer la formation d'une embase de stabilité, la ligne de marquage principale est combinée avec des lignes de marquage obliques formées entre ladite ligne principale et le fond.To improve the formation of a stability base, the line of main marking is combined with oblique marking lines formed between said main line and the bottom.

Avantageusement, la ligne de marquage est formée sur chacune des parois.Advantageously, the marking line is formed on each of the walls.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective d'un sac d'emballage selon l'invention, en position verticale stable ;
  • la figure 2 est une vue de face du sac ;
  • la figure 3 est une vue en coupe transversale, considérée selon la ligne 3-3 de la figure 2 ;
  • la figure 4 est une vue en coupe longitudinale du sac, représenté à plat, à la sortie d'une machine de fabrication ;
  • la figure 5 est une vue correspondant à la figure 4, après mise en forme du sac montrant la formation de l'embase de stabilité verticale.
The invention is set out below in more detail with the aid of the figures of the appended drawings in which:
  • Figure 1 is a perspective view of a packaging bag according to the invention, in a stable vertical position;
  • Figure 2 is a front view of the bag;
  • Figure 3 is a cross-sectional view, taken along line 3-3 of Figure 2;
  • Figure 4 is a longitudinal sectional view of the bag, shown flat, at the outlet of a manufacturing machine;
  • Figure 5 is a view corresponding to Figure 4, after shaping the bag showing the formation of the vertical stability base.

Pour une meilleure compréhension des dessins, les épaisseurs des parties constitutives du sac ont volontairement été exagérées.For a better understanding of the drawings, the thicknesses of the constituent parts of the bag have been deliberately exaggerated.

L'invention s'applique à la réalisation de sacs en matière plastique (1) obtenus par tout moyen connu et approprié. Par exemple, le sac (1) peut être obtenu à partir d'une bobine de film en matière plastique soumis, en continu, à différentes opérations, notamment de pliage et de soudure réalisées, d'une manière automatique. La matière plastique utilisée peut être, par exemple, du PE additionné d'OPP ou bien du PE additionné de PET.The invention applies to the production of plastic bags (1) obtained by any known and appropriate means. For example, the bag (1) can be obtained from a reel of plastic film submitted, in continuous, for different operations, including bending and welding performed, automatically. The plastic used can be, for example, PE supplemented with OPP or else PE supplemented with FART.

Comme indiqué, le film de matière plastique est soumis à différentes opérations pour obtenir un sac (1) présentant deux parois (1a) et (1b) réunies par des bords transversaux (1c) et (1d) et des bords latéraux (1e) et (1f). Au niveau du bord transversal inférieur (1d), les parois (1a) et (1b) sont convenablement soudées ou autrement assemblées, pour constituer un fond. A l'opposé, le bord transversal (1c) peut être ouvert ou bien fermé, également par soudure ou autrement, en étant assujetti à tout moyen apte à créer une ouverture temporaire donnant libre accès à l'intérieur du sac, cette ouverture pouvant être refermée et réouverte à volonté.
   De telles dispositions ne sont pas décrites en détail, car parfaitement connues pour un homme du métier. De même, les bords latéraux (1e) et (1f) sont conformés en soufflets résultant de deux plis symétriques identiques (1e1) - (1e2) et (1f1) ― (1f2).As indicated, the plastic film is subjected to different operations to obtain a bag (1) having two walls (1a) and (1b) joined by transverse edges (1c) and (1d) and lateral edges (1e) and (1f). At the lower transverse edge (1d), the walls (1a) and (1b) are suitably welded or otherwise assembled, to form a bottom. In contrast, the transverse edge (1c) can be open or closed, also by welding or otherwise, by being subject to any means capable of creating a temporary opening giving free access to the interior of the bag, this opening can be closed and reopened at will.
Such arrangements are not described in detail, since they are perfectly known to a person skilled in the art. Similarly, the lateral edges (1e) and (1f) are shaped as bellows resulting from two identical symmetrical folds (1e1) - (1e2) and (1f1) - (1f2).

Selon une caractéristique à la base de l'invention, au moins l'une des parois (1a) du sac présente, au moment de sa fabrication, une ligne de marquage (2) apte à constituer une zone de pliure. Cette zone de pliure (2) est déterminée pour former et délimiter le fond par rapport aux parois (1a) et (1b), en créant une embase d'appui (1g) sous l'effet de l'écartement des soufflets (1e1) - (1e2) et (1f1) ― (1f2) (figure 1), pour assurer une bonne stabilité, en position verticale, du sac.According to a characteristic underlying the invention, at least one of the walls (1a) of the bag has, at the time of its manufacture, a line of marking (2) capable of constituting a fold zone. This fold zone (2) is determined to form and delimit the bottom relative to the walls (1a) and (1b), by creating a support base (1g) under the effect of the spacing of the bellows (1e1) - (1e2) and (1f1) - (1f2) (figure 1), to ensure good stability, in vertical position, of the bag.

Le marquage (2) est formé parallèlement au fond (1d). Cette ligne de marquage (2) est située à une distance (a) du fond (1d) correspondant, sensiblement, à la moitié de la largeur des soufflets latéraux, c'est-à-dire sensiblement à la longueur d'un pli (1e1) - (1e2) ou (1f1) ― (1f2). La ligne de marquage (2) est réalisée lors de la fabrication en continu du sac, et est de préférence réalisée par marquage sur chacune des parois (1a) et (1b) Ce marquage linéaire (2) est effectué par tout moyen connu et approprié, apte à casser les « molécules » du film en matière plastique. Ce marquage peut être effectué à chaud ou à froid. The marking (2) is formed parallel to the bottom (1d). This line of marking (2) is located at a distance (a) from the corresponding bottom (1d), substantially, at half the width of the side bellows, i.e. approximately the length of a fold (1e1) - (1e2) or (1f1) - (1f2). Line marking (2) is carried out during the continuous manufacture of the bag, and is preferably produced by marking on each of the walls (1a) and (1b) Ce linear marking (2) is carried out by any known and appropriate means, suitable for break the "molecules" of the plastic film. This marking can be performed hot or cold.

Comme le montre la figure 2, la ligne de marquage (2) peut également être combinée avec des lignes de marquage obliques (3) formées entre ladite ligne (2) et le fond (1d).As shown in Figure 2, the marking line (2) can also be combined with oblique marking lines (3) formed between said line (2) and the bottom (1d).

Il en résulte, compte tenu de ces dispositions, qu'après remplissage du sac, correspondant à l'écartement des soufflets, la ligne de marquage (2) peut parfaitement délimiter une embase d'appui pour créer un fond, assurant une parfaite stabilité en position verticale du sac. Ainsi réalisé, le sac peut donc être déplacé d'un poste à un autre, dans le cadre d'une machine de conditionnement automatique, par exemple, sans aucun risque de renversement.It follows, having regard to these provisions, that after filling of the bag, corresponding to the spacing of the bellows, the marking line (2) can perfectly delimit a support base to create a bottom, ensuring perfect stability in vertical position of the bag. Thus produced, the bag can therefore be moved from one position to another, as part of a machine automatic packaging, for example, without any risk of reversal.

Les avantages ressortent bien de la description.The advantages are apparent from the description.
