Abstract
Description
La présente invention concerne la manipulation des produits présentés en rouleaux et plus particulièrement des pellicules en matière plastique destinées à l'emballage des produits les plus divers.The present invention relates to the handling of the products presented in rolls and more particularly plastic films intended for the packaging of the most diverse products.
La déposante a déjà décrit, dans son brevet français 85/10274 les problèmes soulevés par l'utilisateur de ces rouleaux : pour emballer un produit donné, l'opérateur immobilise l'extrémité libre de la pellicule en un point du produit, et enroule ensuite cette pellicule tout autour du produit, en la déroulant au fur et à mesure du rouleau, jusqu'à ce que l'emballage soit achevé, à la suite de quoi le produit se trouve enfermé dans un volume de pellicule adhérant sur elle-même.The applicant has already described, in her French patent 85/10274 the problems raised by the user of these rollers: to package a given product, the operator immobilizes the free end of the film at a point on the product, and then wraps this film all around the product, unrolling it as the roll, until the packaging is completed, after which the product is enclosed in a volume of film adhering to itself.
Comme indiqué dans ce brevet antérieur, l'inconvénient et la difficulté de cette technique, par ailleurs commode et efficace, viennent du poids et des dimensions du rouleau, surtout au début de son utilisation, poids auquel vient s'ajouter le poids d'un appareil dérouleur lourd et peu maniable. En effet, l'opérateur doit alors à la fois déplacer le rouleau et l'appareil dérouleur autour du produit et le faire tourner sur lui-même pour en dérouler la pellicule. L'absence de toute prise sur le manchon rend cette opération pénible et fatigante et peu précise.As indicated in this prior patent, the disadvantage and difficulty of this technique, which is moreover convenient and effective, comes from the weight and dimensions of the roller, especially at the start of its use, weight to which is added the weight of a heavy unwieldy unwinding device. Indeed, the operator must then both move the roller and the unwinding device around the product and rotate it on itself to unwind the film. The absence of any grip on the sleeve makes this operation painful and tiring and imprecise.
Ledit brevet antérieur apportait une première solution à ce problème, grâce à des embouts spécialement conçus pour s'adapter aisément à l'intérieur du manchon de carton, et permettre ensuite de manipuler le rouleau autour du produit en en déroulant et étirant la pellicule avec facilité et précision.Said prior patent provided a first solution to this problem, thanks to specially designed end caps which are easily adapted to the interior of the cardboard sleeve, and then allow the roller to be manipulated around the product by unrolling and stretching the film with ease. and precision.
La présente invention concerne une variante de ce moyen, présentant l'avantage d'assurer non seulement le maintien du mandrin mais aussi son freinage, en vue de provoquer un étirement de la pellicule.The present invention relates to a variant of this means, having the advantage of ensuring not only the maintenance of the mandrel but also its braking, with a view to causing stretching of the film.
Par ailleurs l'invention vise un nouveau mode d'utilisation de ces pellicules, permettant d'atteindre une solution à un problème bien connu, à savoir celui de l'aération, souvent nécessaire, de produits par ailleurs maintenus sans film étirable étanche. Cette solution consiste, selon l'invention, à substituer aux rouleaux de pellicule de grande largeur, des bobines de pellicule beaucoup plus étroites, pouvant être désignées par "lanières", et dont l'enroulement autour des produits, suivant deux hélices croisées, assure le maintien dudit produit et en même temps laisse subsister entre deux tours des vides permettant l'aération du produit.Furthermore, the invention aims at a new mode of use of these films, making it possible to reach a solution to a well-known problem, namely that of the aeration, often necessary, of products otherwise kept without a tight stretch film. This solution consists, according to the invention, in replacing the rolls of film of great width, much narrower film reels, which can be designated by "strips", and whose winding around the products, following two crossed helices, ensures maintaining said product and at the same time leaving voids between two turns allowing the aeration of the product.
L'invention vise donc en premier lieu, un nouveau système de maintien d'un rouleau de pellicule plastique étirable, consistant à prévoir, sur la longueur totale du mandrin, une zone suffisamment large pour permettre le passage d'au moins une main, cette zone étant recouverte d'un manchon fendu, laissant normalement librement tourner le mandrin pendant le déroulage du film, et pouvant être comprimé à la main sur le mandrin, pour freiner sa rotation, pendant l'étirage du film.The invention therefore relates firstly, to a new system for holding a roll of stretchable plastic film, consisting in providing, over the total length of the mandrel, an area large enough to allow the passage of at least one hand, this area being covered with a split sleeve, normally allowing the mandrel to rotate freely during the unwinding of the film, and which can be compressed by hand on the mandrel, to slow down its rotation, during the stretching of the film.
Selon une première réalisation, le mandrin porte un seul rouleau de film, et son prolongement se présente sous forme d'une poignée sur laquelle est enfilé ledit manchon, une butée ou un rebord empêchant ledit manchon de s'échapper.According to a first embodiment, the mandrel carries a single roll of film, and its extension is in the form of a handle on which said sleeve is threaded, a stop or a flange preventing said sleeve from escaping.
Selon une seconde variante, le mandrin porte deux rouleaux de film, séparés par une zone sur laquelle est placé ledit manchon, le système se présentant sous l'aspect d'une haltère.According to a second variant, the mandrel carries two rolls of film, separated by an area on which said sleeve is placed, the system being in the form of a dumbbell.
En second lieu l'invention vise un nouveau procédé d'emballage de produits susceptibles de donner lieu à une condensation, soit par leur nature, tels que fruits, légumes, produits de la mer et analogues, soit à la suite de changements de température, tels que les produits emballés à la suite d'une cuisson ou d'un étuvage, par exemple les yaourts, ce procédé consistant à enrouler autour de ces produits une bande étroite de film étirable, de manière que cet enroulement assure le maintien du produit tout en laissant subsister entre les spires de cette bande des zones non recouvertes, et permettant l'aération et la respiration du produit.Secondly, the invention relates to a new process for packaging products liable to give rise to condensation, either by their nature, such as fruit, vegetables, seafood and the like, or following temperature changes, such as products packaged following baking or parboiling, for example yoghurts, this process consisting in wrapping around these products a narrow strip of stretch film, so that this winding maintains the product while leaving uncovered areas between the turns of this strip, and allowing the aeration and breathing of the product.
On va maintenant décrire l'invention plus en détail en se référant au dessin annexé, sur lequel :
- - la figure 1 représente en perspective le premier mode de réalisation de l'invention ;
- - la figure 2 est une vue de face du second mode de réalisation de l'invention et,
- - la figure 3 illustre le nouveau mode d'emballage selon l'invention.
- - Figure 1 shows in perspective the first embodiment of the invention;
- FIG. 2 is a front view of the second embodiment of the invention and,
- - Figure 3 illustrates the new packaging method according to the invention.
On a représenté à la figure 1 un rouleau de film plastique étirable 1, sur son mandrin support 2. Selon l'invention, ce mandrin 2 se prolonge en 3 pour former une poignée ayant au moins la largeur d'une main 4, et sur ce prolongement est enfilé un manchon 5 fendu en 6 le long d'une génératrice, et ayant au repos un diamètre légèrement supérieur à celui du mandrin 2..Un rebord 7 empêche le manchon de s'échapper.FIG. 1 shows a roll of plastic stretch film 1, on its
L'utilisation de ce système est la suivante : l'opérateur déroule le film 1 autour du produit à emballer, en laissant le mandrin et le rouleau tourner librement dans le manchon 5. Pour étirer le film, par exemple en début ou fin d'opération, il suffit de comprimer le manchon 5 sur le mandrin 2 pour le freiner. Généralement le mandrin est en carton. Le manchon peut être également en carton, ou en matière plastique souple.The use of this system is as follows: the operator unrolls the film 1 around the product to be packaged, leaving the mandrel and the roller to rotate freely in the
Le système de la figure 2 est semblable, mais symétrique : le mandrin 2 porte deux rouleaux de films 1 et 1', et la zone de maintien 3 est située au milieu. Le manchon fendu 5 est donc simplement placé sur cette zone 3 en écartant élastiquement la fente 6, et ne peut plus s'échapper.The system of FIG. 2 is similar, but symmetrical: the
On peut alors utiliser les rouleaux 1 et l' soit successivement, soit simultanément, de la même manière que précédemment.The rollers 1 can then be used and either successively or simultaneously, in the same manner as above.
La figure 3 montre, à titre d'exemple, une série de quatre pots de yaourts 10, 11, 12, 13 réunis par une bande de carton 14, et emballés conformément à l'invention par deux lanières 15 et 16 en film étirable, la lanière 15 étant enroulée en hélice dans un sens, et la lanière 16 étant enroulée en sens contraire.FIG. 3 shows, by way of example, a series of four
Les spires de ces deux lanières s'entrecroisent en laissant subsister entre elles des zones libres 17. Il en résulte que les pots 10-14, tout en étant parfaitement maintenus, ne sont cependant pas privés d'aération, ce qui permet à l'humidité de s'échapper au lieu de se condenser sur l'emballage, comme c'est le cas lors de l'emballage complètement étanche du moyen d'une pellicule continue de grande largeur.The turns of these two strips intersect, leaving free areas between them 17. As a result, the pots 10-14, while being perfectly maintained, are not, however, ventilated, which allows the moisture to escape instead of condensing on the packaging, as is the case with completely sealed packaging using a continuous film of large width.
Bien entendu le cas particulier illustré par la figure 3 ne présente aucun caractère limitatif, notamment quant aux dimensions des produits emballés par le procédé selon l'invention.Of course, the particular case illustrated in FIG. 3 has no limiting character, in particular as to the dimensions of the products packaged by the method according to the invention.
En particulier il doit être clair que ce système s'applique notamment à la palettisation d'objets ou de charges sur palettes.In particular, it should be clear that this system applies in particular to the palletization of objects or loads on pallets.
