Abstract

A bag made of flexible synthetic material is provided with a removable stiffening element that can serve as both a handle and a stopper element after the bag has been opened.

Description

La présente invention a pour objet un sachet en matière synthétique souple pour le conditionnement des liquides du type comportant une poignée de rigidification et de préhension constituée essentiellement par un élément rigide ou semi-rigide disposé à l'intérieur d'une cavité secondaire, séparée de la cavité principale contenant le liquide par une ligne continue de soudure.The present invention relates to a flexible plastic bag for packaging liquids of the type comprising a stiffening and gripping handle essentially consisting of a rigid or semi-rigid element disposed inside a secondary cavity, separated from the main cavity containing the liquid by a continuous line of welding.

L'invention a également pour objet un chapelet de tels sachets. - The invention also relates to a string of such sachets. -

Des sachets de ce type sont connus. Ils ont fait l'objet de la demande de brevet français n° 80.02187 au nom de la demanderesse.Sachets of this type are known. They were the subject of French patent application No. 80.02187 in the name of the applicant.

Les sachets décrits dans cette demande, à laquelle il est fait ici expressément référence, comportent tous un moyen de rigidification solide incorporé à la cavité secondaire précitée. Les différentes solutions proposées donnent entière satisfaction.The bags described in this application, to which express reference is made here, all comprise a solid stiffening means incorporated in the aforementioned secondary cavity. The different solutions offered are entirely satisfactory.

L'ouverture du sachet s'opère par découpe du coin supérieur opposée à la poignée.The bag is opened by cutting the upper corner opposite the handle.

On a cependant constaté que l'un des problèmes posés à l'utilisateur était le rebouchage du sachet après un premier usage. En effet, il est peu probable que le contenu d'un tel sachet, par exemple, 1 litre, soit utilisé en une seule fois, et il est donc nécessaire pour une simple raison d'hygiène et de sécurité, de pouvoir reboucher le sachet.However, it was found that one of the problems posed to the user was the filling of the bag after a first use. Indeed, it is unlikely that the content of such a sachet, for example, 1 liter, is used at one time, and it is therefore necessary for a simple reason of hygiene and safety, to be able to recap the sachet .

Partant de la constatation que la nécessité du bouchage nait lorsque s'éteint celle de la préhension, l'idée s'est alors imposée de tenter de concilier les impératifs des deux fonctions.Starting from the observation that the need for capping arises when the need for grasping dies out, the idea is therefore imposed to try to reconcile the imperatives of the two functions.

La présente invention a en conséquence pour objet de proposer un sachet du type décrit ci-dessus qui permette d'optimiser, à moindre coût, les impératifs des fonctions de préhension d'une part et de bouchage d'autre part.The present invention therefore aims to provide a bag of the type described above which allows optimize, at lower cost, the requirements of the gripping functions on the one hand and of the capping on the other hand.

Conformément à l'invention, ce résultat est obtenu avec un sachet en matière synthétique souple pour le conditionnement des liquides, du type comportant une poignée de rigidification et de préhension, constituée essentiellement par un élément rigide ou semi-rigide disposé à l'intérieur d'une cavité secondaire séparée de la cavité principale contenant le liquide par une ligne continue de soudure, caractérisé en ce que l'élément rigide ou semi-rigide est disposé amovible dans ladite cavité secondaire, afin de pouvoir être utilisé comme élément de bouchage du sachet après ouverture de celui-ci.According to the invention, this result is obtained with a flexible plastic bag for packaging liquids, of the type comprising a stiffening and gripping handle, essentially constituted by a rigid or semi-rigid element placed inside the '' a secondary cavity separated from the main cavity containing the liquid by a continuous line of welding, characterized in that the rigid or semi-rigid element is disposed removably in said secondary cavity, so that it can be used as a plugging element for the sachet after opening it.

Ainsi on utilise le même élément pour assurer successivement la préhension et le bouchage du sachet. Bien entendu, cet élément pourra affecter des formes multiples devant simplement être compatibles avec les deux fonctions.Thus the same element is used to successively ensure the gripping and the plugging of the sachet. Of course, this element can have multiple forms which simply have to be compatible with the two functions.

De manière avantageuse, l'élément rigide se présentera sous la forme d'un corps creux oblong, nécessairement obturé à au moins l'une de ses extrémités et de forme générale effilée. Il sera préférentiellement de sections sans angles vifs.Advantageously, the rigid element will be in the form of an oblong hollow body, necessarily closed at at least one of its ends and of generally tapered shape. It will preferably be of sections without sharp angles.

Cette réalisation présente, par rapport aux réalisations de l'art antérieur, des avantages multiples tels que, non limitativement :

  • - réalisation d'un bouchage simple et compréhensible aisément par tout utilisateur,
  • - économie du fait de l'utilisation d'un seul élément pour deux fonctions différentes,
  • - apport d'un avantage supplémentaire sans remettre en cause les autres paramètres (inviolabilité, etc...)
This embodiment has, compared to the embodiments of the prior art, multiple advantages such as, without limitation:
  • - realization of a simple and easily understandable closure by any user,
  • - economy due to the use of a single element for two different functions,
  • - providing an additional advantage without calling into question the other parameters (inviolability, etc.)

L'élément rigide peut être réalisé en toute matière synthétique de qualité alimentaire. Il peut également servir de support publicitaire ou d'information du consommateur.The rigid element can be made of any food-grade synthetic material. It can also serve as advertising or consumer information support.

Les sachets objets de l'invention pouvant également être présentés sous forme de chapelets de sachets et non plus sous forme individuelle, il suffira d'un seul élément rigide par chapelet, ce qui entraîne un gain supplémentaire de matière.The sachets which are the subject of the invention can also be presented in the form of strings of sachets and no longer in individual form, a single rigid element will be sufficient per chain, which results in an additional gain in material.

0n comprendra mieux l'invention à l'aide de la description ci-aprèsd'un mode non limitatif de mise en oeuvre, en référence aux dessins annexés dans lesquels,

  • - la figure 1 est une vue schématique en élévation latérale du sachet conforme à l'invention,
  • - la figure 2 est une vue schématique en élévation latérale du sachet de la figure 1 en position de versage,
  • - la figure 3 est une vue schématique en élévation latérale du sachet de la figure 1 en position de bouchage.
We will better understand the invention using the following description of a non-limiting mode of implementation, with reference to the accompanying drawings in which,
  • FIG. 1 is a schematic side elevation view of the bag according to the invention,
  • FIG. 2 is a schematic side elevation view of the bag of FIG. 1 in the pouring position,
  • - Figure 3 is a schematic side elevational view of the bag of Figure 1 in the plugging position.

Le sachet (1) se compose de manière en elle-même connue, et qui ne sera donc pas explicitée plus en détails, d'une cavité principale (2) destinée à recevoir les liquides à conditionner et d'une cavité secondaire (3) séparée de ladite cavité principale par une ligne de soudure continue (4) de tracé quelconque, rectiligne ou non.The bag (1) is made up in itself known, and which will therefore not be explained in more detail, of a main cavity (2) intended to receive the liquids to be packaged and of a secondary cavity (3) separated from said main cavity by a continuous weld line (4) of any shape, straight or not.

Le fond du sachet peut être de toute structure, par exemple en W ou en plat.The bottom of the bag can be of any structure, for example in W or flat.

Les deux parois du sachet peuvent provenir d'un même film replié adéquatement ou de deux bandes distinctes.The two walls of the sachet can come from the same adequately folded film or from two separate strips.

De la même manière, le sachet peut être réalisé aussi bien dans une machine dite horizontale que dans une machine verticale utilisant un mandrin vertical de formage du film en gaine.Likewise, the sachet can be produced both in a so-called horizontal machine and in a vertical machine using a vertical film-forming mandrel in sheath.

Conformément à l'invention, on dispose dans la cavité (3) un élément rigide (5) amovible.According to the invention, there is in the cavity (3) a rigid element (5) removable.

La cavité (3) pourra par exemple être ouverte sur son chant supérieur pour permettre le retrait de l'élément (5) par l'utilisateur. Eventuellement l'élément (5) fera légèrement saillie en dehors de la cavité (3).The cavity (3) may for example be open on its upper edge to allow the removal of the element (5) by the user. Optionally the element (5) will protrude slightly outside the cavity (3).

La cavité (3) pourra également être fermée par une ligne de soudure (6) éventuellement munie d'une prédécoupe. L'utilisateur utilise donc par exemple des ciseaux pour découper cette ligne ou déchire selon la ligne de prédécoupe. On préserve ainsi l'hygiène.The cavity (3) can also be closed by a weld line (6) possibly provided with a precut. The user therefore uses for example scissors to cut this line or tears according to the precut line. We preserve thus hygiene.

Pour le versage proprement dit, l'utilisateur découpe de manière classique le coin supérieur (7) du sachet opposé à la poignée, pour déterminer un orifice de versage (8). Le versage est illusté à la figure 2, l'élément rigide (5) étant disposé dans la cavité (3) et jouant donc son rôle de rigidification pour le versage.For the actual pouring, the user conventionally cuts the upper corner (7) of the bag opposite the handle, to determine a pouring orifice (8). The pouring is illustrated in FIG. 2, the rigid element (5) being disposed in the cavity (3) and therefore playing its role of stiffening for the pouring.

Une fois le versage terminé, l'utilisateur retire l'élément (5) et le dispose dans l'orifice (8) comme représenté à la figure 3.Once the pouring is completed, the user removes the element (5) and places it in the orifice (8) as shown in Figure 3.

De manière à permettre une compatibilité de l'élément (5) avec tous les diamètres d'orifices (8), qui sont aléatoires, sauf s'il y a prédécoupe ou zone déterminée d'ouverture, du fait d'une découpe par ciseaux, la section de l'élément oblong (5) sera décroissante progressivement d'une extrémité de l'élément à l'autre. On facilite ainsi en outre l'insertion dans l'orifice (8).In order to allow compatibility of the element (5) with all the diameters of orifices (8), which are random, unless there is a precut or determined opening area, due to cutting by scissors , the section of the oblong element (5) will decrease progressively from one end of the element to the other. This also facilitates insertion into the orifice (8).

L'élément (5) sera obturé de préférence à son extrémité de section la plus faible, pour des raisons d'hygiène.The element (5) should preferably be closed at its end with the smallest section, for hygienic reasons.

Comme représenté à la figure 3, on constatera que l'élement (5) en fonction de bouchage, peut également servir d'élément de préhension et de portage du sachet, en le prenant par le dessus. On évite ainsi, par rapport à une préhension et un portage latéraux, une expulsion intempestive du bouchon et du contenu du sachet.As shown in Figure 3, we will see that the element (5) as a function of blocking, can also serve as a gripping and carrying element of the bag, by taking it from above. This prevents unwanted expulsion of the stopper and the contents of the sachet, compared to lateral gripping and carrying.

Il est clair que l'élément (5) pourra affecter toutes forme et section compatibles avec ses fonctions. Il pourra être transparent ou non et être obturé aux deux extrémités.It is clear that the element (5) may affect any shape and section compatible with its functions. It may or may not be transparent and be closed at both ends.

De manière préférentielle, l'élément (5) viendra s'insérer à frottement dans la cavité (3) qui sera donc ajustée au mieux, pour permettre une meilleure préhension du sachet lors du versage.Preferably, the element (5) will be inserted frictionally into the cavity (3) which will therefore be adjusted as best as possible, to allow better grip of the bag during pouring.

L'invention a également pour objet des chapelets de sachets de ce type, qui peuvent être en alignement vertical ou horizontal. Très avantageusemetn, le chapelet comportera une seule poignée rigide,l'élément (5) pouvant être utilisé pour chaque sachet successivement.The invention also relates to strings of sachets of this type, which can be in vertical or horizontal alignment. Very advantageous, the rosary will include a single rigid handle, the element (5) being able to be used for each bag successively.
