Abstract

The package forms a winder and a transporting case for reels of film or thermoplastic wrapping. It is made of two cardboard cheeks (A,B) of regular polygonal shape. These are assembled, at a given spacing on a central film-carrying mandrel (1). One cheek (8) is lengthened on each flat polygon end by a rectangular tongue (7,7') of a width (L) sufficient that adjacent tongues can turn down along the cheek (A) walls to form a transporting case. Each cheek has two circular perforated lines with one (2) around a cheek centre.

Description

La présente invention a trait au domaine de l'emballage et stockage de film de matiere thermoplastique. Elle concerne plus spécialement un nouvel emballage destiné à servir a la fois de dévidoir et de moyen de transport de film plastique. The present invention relates to the field of packaging and storage of thermoplastic film. It relates more specifically to a new packaging intended to serve both as a reel and as a means of transporting plastic film.

Les bandes de diverses largeurs de films de matiere plastique doivent être enroulées lors de la production sur des bobines ou mandrins de dimensions appropriés pour être ensuite stockées, transportées et/ou soumises à des traitements ultérieurs tels que impression, prédécoupe, etc. C'est le cas, notamment, des gaines plates de matière thermoplastique qui sont destinées è la production et la pose, l'aide d'appareillages appropriés, de manchons décoratifs thermorétractables autour de récipients de diverses formes et dimensions. The strips of various widths of plastic films must be wound during production on reels or cores of appropriate dimensions to be then stored, transported and / or subjected to subsequent treatments such as printing, precut, etc. This is the case, in particular, of flat thermoplastic sheaths which are intended for production and installation, using appropriate equipment, decorative heat-shrink sleeves around containers of various shapes and dimensions.

L'utilisation directe et immédiate ou, pis encore, le stockage et le transport de ces bobines de films ou gaines plates posent divers types de problèmes. Tout d'abord le film ou gaine doit être isolé des chocs et les spires enroulées ne doivent pas se déplacer les unes par rapport aux autres, y compris lorsqu'on exerce une traction, par exemple dans le cas de la fabrication susvisée de manchons pour récipients. Ensuite, lors du transport ou des manutentions, les bobines pleines doivent être disposées dans des contenants ou caisses spéciales de transport, afin d'éviter toute détérioration par choc de la bobine et du film ou gaine. Direct and immediate use or, worse still, storage and transportation of these film reels or flat sleeves pose various types of problems. First of all the film or sheath must be isolated from shocks and the coiled turns must not move relative to each other, including when pulling is applied, for example in the case of the abovementioned manufacture of sleeves for containers. Then, during transport or handling, the full reels must be placed in special transport containers or boxes, in order to avoid any damage by shock of the reel and the film or sheath.

I1 a maintenant été trouvé que ces problèmes pouvaient être résolus grâce à un emballage pouvant jouer le rôle d'enrouleur-dévidoir et de moyen de stockage et transport de bande de film ou gaine plate thermoplastique. L'invention propose à cet effet un nouvel emballage rationnel pour bobine dans lequel le film plastique est isolé des chocs, permet des enroulements-déroulements de bandes sans décalage des spires et qui ne nécessite pas l'utilisation de caisses de transport.En outre, un tel emballage peut être utilisé directement comme magasin d'alimentation de machines destinées à des traitements ultérieurs de la bande de film comme par exemple des dispositifs è traction de gaine pour découpe et pose de manchons autour de récipients,
L'emballage selon l'invention est essentiellement constitué par deux flasques en carton, ayant la forme de polygones réguliers identiques et aptes è être assemblés è intervalle donné et variable autour d'un mandrin central porteur du film plastique, l'un des flasques étant prolongé sur chacune des arêtes planes du polygone par une languette rectangulaire de largeur telle que, apres introduction du bobinage de film sur le mandrin, l'ensemble des languettes adjacentes puisse se rabattre le long des parois du flasque simple, dépourvu de languettes, de façon a constituer une boite de transport.
I1 has now been found that these problems can be solved by means of packaging which can act as a reel-reel and a means of storing and transporting a film strip or thermoplastic flat sheath. To this end, the invention proposes a new rational packaging for reels in which the plastic film is insulated from shocks, allows the winding and unrolling of bands without shifting the turns and which does not require the use of transport cases. such packaging can be used directly as a supply store for machines intended for subsequent processing of the film strip, for example sheath traction devices for cutting and fitting sleeves around containers,
The packaging according to the invention essentially consists of two cardboard flanges, having the shape of identical regular polygons and able to be assembled at given and variable intervals around a central mandrel carrying the plastic film, one of the flanges being extended on each of the flat edges of the polygon by a rectangular tongue of width such that, after introduction of the film winding on the mandrel, the set of adjacent tongues can be folded down along the walls of the simple flange, devoid of tongues, so to constitute a transport box.

Selon une caractéristique de l'invention, chacun des flasques est muni de deux lignes circulaires de prédécoupe ou microperforations à savoir : un premier petit cercle autour du centre du cercle du flasque sur lequel est inscrit le polygone puis uzi second cercle prédécoupé dont le diamètre est légèrement supérieur a celui du mandrin destiné è supporter les spires du film.Lors de l'utilisation de l'emballage, c'est 9 dire au moment de la transformation de ce dernier de caisse de transport en dévidoir, on perfore par appui du doigt le petit cercle microperforé puis on extrait par traction la prédecoupe correspondant au second cercle de façon d pouvoir installer le dévidoir sur l'arbre ou axe de travail pour le bobinage du film. According to a characteristic of the invention, each of the flanges is provided with two circular pre-cut lines or microperforations, namely: a first small circle around the center of the circle of the flange on which the polygon is inscribed then uzi second precut circle whose diameter is slightly higher than that of the mandrel intended to support the turns of the film. When using the packaging, that is to say when the latter is transformed from a transport case into a reel, punctured by pressing the finger the small microperforated circle then the pre-cut corresponding to the second circle is extracted by traction so as to be able to install the reel on the shaft or work axis for winding the film.

Selon une autre caractéristique, les languettes rabattues sur toute la périphérie pour fermer l'espace entre les deux flasques comportent au moins une fente transversale destinée a laisser passer une extrémité du film. Cette dernière est par exemple collée sur l'emballage lors du transport puis libérée lors de l'utilisation ultérieure du film sur le bobinoir. According to another characteristic, the tabs folded over the entire periphery to close the space between the two flanges have at least one transverse slot intended to allow one end of the film to pass. The latter is for example glued to the packaging during transport and then released during the subsequent use of the film on the winder.

En pratique, grâce è l'espace ménagé entre le mandrin porteur du film et le grand cercle découpé et grâce a la structure périphérique è arêtes planes des flasques, l'emballage selon l'invention peut rester fixe (par exemple calé sur une surface plane) pendant que le dévidoir travaille en rotation pour un traitement du film ou de la gaine plastique. On évite ainsi, en particulier, toute détérioration du film pendant son déroulement (qui peut être irrégulier ou intempestif) et les inconvénients dus au décalage des spires notamment dans le cas de l'utilisation des gaines plates decorées de film thermoplastique pour la confection et pose des manchons autour de récipients. In practice, thanks to the space provided between the film-carrying mandrel and the large cut circle and thanks to the peripheral structure with flat edges of the flanges, the packaging according to the invention can remain fixed (for example wedged on a flat surface ) while the reel is working in rotation to process the film or plastic sheath. This avoids, in particular, any deterioration of the film during its unwinding (which can be irregular or untimely) and the drawbacks due to the offset of the turns in particular in the case of the use of flat sheaths decorated with thermoplastic film for making and laying sleeves around containers.

L'invention sera mieux comprise et d'autres détails seront mis en exergue par une description détaillée d'un mode de réalisation illustré par les dessins de la planche annexée, qui représentent schématiquement
Figures I a et lb : les deux éléments essentiels d'un
emballage selon l'invention

L'emballage tel que représenté comporte deux flasques A et B de même structure polygonale, par exemple ici un octogone, et destinés à être assemblés à distance autour d'un mandrin 1 porteur du bobinage d'une bande de film ou gaine plate thermoplastique (non représentée).
The invention will be better understood and other details will be highlighted by a detailed description of an embodiment illustrated by the drawings of the appended plate, which schematically represent
Figures I a and lb: the two essential elements of a
packaging according to the invention
Figure 2: a sectional view illustrating the function of a
rectangular tabs visible in Figure Ib;
The packaging as shown comprises two flanges A and B of the same polygonal structure, for example here an octagon, and intended to be assembled remotely around a mandrel 1 carrying the winding of a film strip or flat thermoplastic sheath ( not shown).

Ces deux flasques comportent chacun des microperforations en forme, par exemple, de cercles 2 et 3 servant de lignes de prédécoupe au moment où il s'agit de transformer l'emballage depuis son stade initial de boîte de transport en son utilisation finale de dévidoir ou magasin d'alimentation d'une machine de traitement de film.These two flanges each have microperforations in the form, for example, of circles 2 and 3 serving as precut lines when it comes to transforming the packaging from its initial stage of transport box into its final use of dispenser or film processing machine feed store.

Bien que d'autres matériaux puissent être utilisés pour la confection des flasques, il est commode et peu coûteux de les réaliser en carton, par exemple ondulé ou multipliés.  Although other materials can be used for making the flanges, it is convenient and inexpensive to make them out of cardboard, for example corrugated or multiplied.

Selon une originalité de l'invention, le flasque B est pourvu, sur chaque face plane du polygone, d'une languette.7,i',7" ... découpée en forme de rectangle et qui est solidaire de ladite face. Chaque languette est prévue avec deux rainures ou pliures, l'une (4) au niveau de l'arête plane du polygone et l'autre (5) à une certaine distance (1) du bord supérieur de la languette. Ces languettes repliables 7 sont conçues pour servir de rabats au-dessus de l'intervalle de séparation entre les deux flasques A et B assemblés autour de leur mandrin commun 1. Leur longueur L doit donc être suffisante pour recouvrir cet intervalle puis se replier selon 1 (voir figure 2) sur le flasque A en constituant ainsi une boîte ou caisse de transport fermée de tout côté et protégeant entièrement le film bobiné sur le mandrin 1. La longueur L est bien entendu déterminée selon les largeurs des bandes du film que l'on droit transporter et traiter ensuite. According to an originality of the invention, the flange B is provided, on each flat face of the polygon, with a tongue. 7, i ', 7 "... cut into the shape of a rectangle and which is integral with said face. Each tongue is provided with two grooves or folds, one (4) at the level of the flat edge of the polygon and the other (5) at a certain distance (1) from the upper edge of the tongue. These folding tongues 7 are designed to serve as flaps above the separation interval between the two flanges A and B assembled around their common mandrel 1. Their length L must therefore be sufficient to cover this interval and then fold back according to 1 (see FIG. 2) on the flange A thus constituting a transport box or crate closed on all sides and fully protecting the film wound on the mandrel 1. The length L is of course determined according to the widths of the strips of film which are to be transported and processed then.

En un point au moins de la périphérie l'une des languettes comporte une fente transversale 6 qui sert à faire passer et amorcer le départ de la bande de film, laquelle peut être appliquée ensuite sur l'emballage par bande adhésive ou moyen équivalent. At at least one point on the periphery, one of the tongues has a transverse slot 6 which serves to pass and initiate the departure of the film strip, which can then be applied to the packaging by adhesive strip or equivalent means.

L'emballage, muni de sa bobine de film et totalement clos pendant le stockage et le transport, est libéré de ses deux disques 3 au moment de l'utilisation en dévidoir, l'ouverture ménagée permettant d'introduire dans le mandrin I l'axe d'entraînement en rotation prévu sur les machines d'alimentation et traitement de film. Comme dit précédemment, les deux flasques A et B restent fixes pendant la rotation du dévidoir du fait de l'espace libre ménagé entre le mandrin 1 et le disque 3 et ces flasques sont calés sur l'une au moins de leurs faces planes. Ainsi le film est protégé et guidé en permanence pendant les tractions plus ou moins régulières et progressives qu'il subit pendant son déroulement. The packaging, provided with its film reel and completely closed during storage and transport, is released from its two discs 3 at the time of use in the reel, the opening made possible to introduce into the mandrel I the rotational drive axis provided on the feeding and film processing machines. As said previously, the two flanges A and B remain fixed during the rotation of the reel because of the free space provided between the mandrel 1 and the disc 3 and these flanges are wedged on at least one of their flat faces. Thus the film is permanently protected and guided during the more or less regular and progressive pulls that it undergoes during its unfolding.

Enfin, selon un mode d'exécution préférentiel de l'invention, les languettes rectangulaires 7,7',7" ... sont préalablement découpées sur chacun de leurs coins supérieurs, par exemple selon les pointillés indiqués sur la figure I b, de façon qu'après rabat de ces languettes il n'y ait pas de chevauchement entre elles.  Finally, according to a preferred embodiment of the invention, the rectangular tongues 7,7 ', 7 "... are cut beforehand on each of their upper corners, for example according to the dotted lines indicated in FIG. so that after flap of these tabs there is no overlap between them.
