Description

La présente invention concerne un sac en matière plastique muni d'une bande de fermeture adhésive dont une partie d'extrémité est fixée de manière permanente audit sac, tandis que son autre partie y est fixée de manière amovible au moyen d'un adhésif approprié. Un tel sac est connu de US-A-4 008 851.The present invention relates to a plastic bag provided with an adhesive closure strip, one end part of which is permanently fixed to said bag, while its other part is detachably fixed thereto by means of a suitable adhesive. Such a bag is known from US-A-4,008,851.

Les sacs en matière plastique, notamment en polyéthylène, sont à l'heure actuelle couramment utilisés pour la collecte des ordures ménagères. Pour assurer la fermeture de tels sacs, on utilise le plus souvent des liens en polypropylène ou métallo-plastiques qui ne sont pas toujours d'un emploi commode. On connaît également des sacs pourvus d'une bande de fermeture adhésive, mais qui ne donnent pas entière satisfaction.Plastic bags, especially polyethylene, are currently commonly used for the collection of household waste. To ensure the closure of such bags, polypropylene or metallo-plastic ties are most often used, which are not always easy to use. There are also known bags provided with an adhesive closure strip, but which are not entirely satisfactory.

La présente invention a pour but de remédier aux inconvénients de la technique antérieure et, pour ce faire, elle a pour objet un sac en matière plastique du type susmentionné qui se caractérisé en ce que le sac comporte deux soufflets latéraux et en ce que la bande adhésive est disposée longitudinalement entre le fond du sac et son ouverture supérieure, de façon à pouvoir être décollée à partir du bas vers le haut, la bande adhésive étant disposée dans la zone médiane entre les deux soufflets.The present invention aims to remedy the drawbacks of the prior art and, to do this, it relates to a plastic bag of the above type which is characterized in that the bag has two lateral bellows and in that the strip adhesive is placed longitudinally between the bottom of the bag and its upper opening, so that it can be peeled from the bottom up, the adhesive strip being placed in the middle area between the two bellows.

Il n'y a ainsi surépaisseur apparente lorsque les sacs sont empilés ou présentés sous forme de rouleau continu. De plus, cette disposition facilite la pose automatique de la bande lors de la confection des sacs.There is thus no apparent allowance when the bags are stacked or presented in the form of a continuous roll. In addition, this arrangement facilitates the automatic installation of the strip when making the bags.

Dans un mode de réalisation particulier de l'invention, l'extrémité de la bande destinée à être décollée est dépourvue d'adhésif sur une partie de sa longueur afin de constituer une amorce de décollement.In a particular embodiment of the invention, the end of the strip intended to be peeled off is devoid of adhesive over part of its length in order to constitute a primer for peeling off.

Une forme d'exécution de l'invention est décrite ci-après à titre d'exemple, en référence au dessin annexé dans lequel :

  • la figure 1 est une vue d'un sac en matière plastique à soufflets conforme à l'invention, représenté à plat ;
  • la figure 2 représente le sac plein, après décollement de la bande de fermeture adhésive ; et
  • la figure 3 représente le sac plein, fermé par la bande adhésive entourant le chignon.
An embodiment of the invention is described below by way of example, with reference to the accompanying drawing in which:
  • Figure 1 is a view of a plastic bag with bellows according to the invention, shown flat;
  • FIG. 2 represents the full bag, after detachment of the adhesive closure strip; and
  • Figure 3 shows the full bag, closed by the adhesive tape surrounding the bun.

Le sac en matière plastique 1 représenté sur la figur 1 est du type de ceux qui sont couramment utilisés pour la collecte des ordures ménagères. Il est réalisé à partir d'une gaine de polyéthylène avec un fond soudé 2 et une ouverture supérieure 3. De plus, il comporte deux soufflets latéraux dont les plis internes sonte indiqués en 4.The plastic bag 1 shown in FIG 1 is of the type that is commonly used for the collection of household waste. It is made from a polyethylene sheath with a welded bottom 2 and an upper opening 3. In addition, it has two lateral bellows whose internal folds are indicated in 4.

Conformément à l'invention, ce sac est pourvu d'une bande de fermeture adhésive 5 disposée longitudinalement entre le fond 2 et l'ouverture supérieure 3, dans la zone médiane située entre les plis internes 4 des deux soufflets latéraux. On limite ainsi au minimum la surépaisseur due à la présence de la bande adhésive, afin de ne pas géner la confection des sacs et en particulier la confection de bobinots. A cet effet, l'épaisseur de la bande sera comprise entre 20 et 100 µ et de préférence inférieure à 60 µ. On notera en outre que cette disposition de la bande, parallèlement à la gaine de polyéthylène constituant les sacs, facilite considérablement la pose repérée à grande vitesse de la bande sur la gaine lors de la confection des sacs, au moyen d'une machine de pose et de coupe adaptée.According to the invention, this bag is provided with an adhesive closure strip 5 arranged longitudinally between the bottom 2 and the upper opening 3, in the median zone located between the internal folds 4 of the two lateral bellows. This minimizes the excess thickness due to the presence of the adhesive strip, so as not to interfere with the making of the bags and in particular the making of reels. For this purpose, the thickness of the strip will be between 20 and 100 μ and preferably less than 60 μ. It will also be noted that this arrangement of the strip, parallel to the polyethylene sheath constituting the bags, considerably facilitates the marked positioning of the strip at high speed on the sheath during the making of the bags, by means of a laying machine. and adapted cutting.

La bande adhésive 5 aura de préférence une longueur comprise entre 15 et 30 cm et une largeur comprise entre 5 et 20 mm, par exemple une longueur de 20 cm et une largeur de 12 mm. Elle est conçue pour être décollée partiellement du sac sur une longueur suffisante pour permettre d'entourer un chignon 6 préalablement réalisé sur la tête du sac, comme illustré sur la figure 2, et de serrer ensuite ce chignon en recollant la bande sur elle-même et sur le sac, comme illustré sur la figure 3. A cet effet, la bande 5 est revêtue d'un adhésif pelable, c'est-à-dire que même après un vieillissement de plusieurs mois, cet adhésif permet un collage suffisant de la bande sur le polyéthylène, tout en permettant de la décoller facilement sans arracher le film de polyéthylène, même en fine épaisseur, soit jusqu'à 15 µ environ.The adhesive strip 5 will preferably have a length of between 15 and 30 cm and a width of between 5 and 20 mm, for example a length of 20 cm and a width of 12 mm. It is designed to be partially detached from the bag over a sufficient length to allow surrounding a bun 6 previously produced on the head of the bag, as illustrated in FIG. 2, and then to tighten this bun by gluing the strip back on itself and on the bag, as illustrated in FIG. 3. For this purpose, the strip 5 is coated with a peelable adhesive, that is to say that even after aging for several months, this adhesive allows sufficient bonding of the strip on the polyethylene, while allowing to take it off easily without tearing off the polyethylene film, even in thin layers, up to around 15 µ.

En revanche, l'adhésif permet un collage puissant sur le support de la bande 5, de manière que lors de la fermeture du sac, la collage de la bande sur elle-même soit quasi définitif. Il pourra s'agir par exemple d'un adhésif acrylique ou caoutchouc, ou de tout autre adhésif présentant les mêmes propriétés vis-à-vis du polyéthylène en film mince et du support de la bande. Quant au support de bande, il appartient avantageusement à une famille de polymères compatible avec le polyéthylène, afin de permettre le recyclage des rebuts de fabrication. Il pourra s'agir par exemple de polypropylène ou de polyéthylène. Bien entendu, la bande devra avoir une résistance suffisante à la traction pour permettre un serrage convenable du chignon 6 du sac.On the other hand, the adhesive allows a strong bonding on the support of the strip 5, so that when the bag is closed, the bonding of the strip on itself is almost final. It may for example be an acrylic or rubber adhesive, or any other adhesive having the same properties vis-à-vis the polyethylene in thin film and the support of the strip. As for the strip support, it advantageously belongs to a family of polymers compatible with polyethylene, in order to allow recycling of manufacturing waste. It may for example be polypropylene or polyethylene. Of course, the strip should have sufficient tensile strength to allow proper tightening of the bun 6 of the bag.

L'extrémité 7 de la bande située du côté de l'ouverture 3 du sac est fixée de manière permanente à la paroi du sac sur une partie de sa longueur, par exemple 10 à 15 mm, par tout procédé approprié, tel que traitement radioactif, U.V. ou thermique. Cette partie non décollable 7 de la bande sera avantageusement située à une distance d'environ 10 à 20 cm de l'ouverture 3 du sac, de préférence 10 à 15 cm, afin de faciliter la formation du chignon 6 à ce niveau.The end 7 of the strip situated on the side of the opening 3 of the bag is permanently fixed to the wall of the bag over a part of its length, for example 10 to 15 mm, by any suitable method, such as radioactive treatment. , UV or thermal. This non-peelable part 7 of the strip will advantageously be located at a distance of approximately 10 to 20 cm from the opening 3 of the bag, preferably 10 to 15 cm, in order to facilitate the formation of the bun 6 at this level.

Ainsi, la bande adhésive 5 doit être décolléé en bas en haut. Afin de faciliter le décollage, l'extrémité opposée 8 de la bande située du côté du fond 2 du sac est avantageusement dépourvue d'adhésif sur une partie de sa longueur, par exemple 5 à 10 mm, de manière à constituer une amorce de décollement. Cette amorce 8 pourrait également être réalisée au moyen d'un intercalaire de même largeur et de même nature que le support de bande, disposé entre le polyéthylène du sac et le début de la bande adhésive sur une longueur d'environ 5 à 10 mm.Thus, the adhesive strip 5 must be peeled down at the top. In order to facilitate take-off, the opposite end 8 of the strip located on the side of the bottom 2 of the bag is advantageously devoid of adhesive over a part of its length, for example 5 to 10 mm, so as to constitute a primer for detachment . This primer 8 could also be produced by means of an interlayer of the same width and of the same nature as the strip support, disposed between the polyethylene of the bag and the start of the adhesive strip over a length of approximately 5 to 10 mm.

Pour faciliter la localisation sur le sac de la bande adhésive de fermeture par l'utilisateur, celle-ci pourra avantageusement avoir une teinte différente du sac polyéthylène lui-même. De plus, la bande pourra éventuellement comporter un texte imprimé expliquant son mode d'utilisation.To facilitate localization on the bag of the adhesive closure tape by the user, the latter may advantageously have a different shade from the polyethylene bag itself. In addition, the strip may possibly include printed text explaining its mode of use.

Pour obturer un sac plein, il suffit, après avoir formé un chignon 6 au niveau de la partie non décollable 7 de la bande adhésive 5, de décoller du sac le reste de la bande en tirant sur l'amorce 8, comme illustré par la figure 2, puis de l'enrouler autour de la partie rétrécie du chignon afin de former un lien 9, comme illustré par la figure 3. Ce faisant, la bande se recolle sur le sac et sur elle-même en assurant la fermeture quasi définitive du sac.To seal a full bag, it is sufficient, after having formed a bun 6 at the level of the non-peelable part 7 of the adhesive strip 5, to peel the rest of the strip from the bag by pulling on the primer 8, as illustrated by the Figure 2, then wrap it around the narrowed part of the bun to form a link 9, as shown in Figure 3. In doing so, the strip sticks to the bag and on itself ensuring the almost permanent closure from the bag.

Les sacs conformes à l'invention présentent donc une grande commodité d'emploi, tout en étant relativement peu coûteux à fabriquer.The bags according to the invention therefore have great convenience in use, while being relatively inexpensive to manufacture.
