Abstract

According to this process, where the section of sheath or sleeve made of heat-shrinkable plastic film is divided beforehand into at least two compartments by welding or adhesively bonding the film, the weld or the adhesive bonding is performed along at least two generatrices of the sleeve to obtain two different lines of vertical bonding between the two compartments.

Description

La présente invention a trait au domaine de ltemballa- ge d'objets sous film plastique transparent thermorétractable, speciale- ment dans le cas ou plusieurs objets, de formes identiques ou differentes, doivent être groupés en un même lot. Elle concerne un procédé d'emballage permettant à divers objets de conserver leur individualité propre tout en faisant partie d'un paquet unitaire, ainsi que les emballages correspondants ainsi obtenus. The present invention relates to the field of packaging articles in transparent heat-shrinkable plastic film, especially in the case where several objects, of identical or different shapes, must be grouped in the same batch. It relates to a packaging method allowing various objects to retain their own individuality while being part of a unitary package, as well as the corresponding packaging thus obtained.

On connait depuis longtemps dans le commerce la présentation de plusieurs objets réunis en un meme emballage constitué par un film plastique etire (par exemple en chlorure de polyninyle) qui, apres thermorétraction, épouse la forme individuelle des objets. En particulier, pour les ventes à promotion publicitaire, on a lthabitude de grouper en un même lot au moins deux articles de même nature ou différents et qui peuvent avoir des dimensions non similaires comme par exémple : une bouteille d'apéritif et son bouchon doseur, un flacon d'eau de toilette et un bon de reduction, ou encore deux bombes aérosols identiques deux flacons de shampooing. etc.  We have known for a long time in the trade the presentation of several objects gathered in a same packaging constituted by a stretched plastic film (for example in polyninyl chloride) which, after heat shrinking, marries the individual shape of the objects. In particular, for sales with advertising promotion, it is customary to group in the same batch at least two articles of the same or different type and which may have dimensions that are not similar, for example: a bottle of aperitif and its measuring cap, a bottle of eau de toilette and a reduction voucher, or two identical aerosol cans two bottles of shampoo. etc.

Lorsqu'on utilise, de façon maintenant bien connue, des tronçons de gaine ou manchons en matière plastique thermorêtractable comportant des impressions et/ou dessins pour enfermer les articles dans le même emballage, on constate assez frequemment des déformations des parties imprimées ou décorées de la gaine du fait du vide créé entre les articles pendant la thermorétraction ou encore parce que ces articles comme par exemple un récipient et un bon de reduction - ont des conformations totalement différentes. When using, in a way which is now well known, sections of sheath or sleeves made of heat-shrinkable plastic comprising prints and / or drawings to enclose the articles in the same packaging, deformations of the printed or decorated parts of the sheath due to the vacuum created between the articles during the heat shrink or because these articles such as for example a container and a reduction coupon - have completely different conformations.

Afin de ren.edier à ces inconvénients on a déjà proposé de créer plusieurs compartiments à partir du film en matière plastique thermorétractable en assurant une liaison, pour soudure ou collage, entre les deux extremites libre du film et le film lui-même, selon une generatri ce ou ligne verticale du manchon ainsi obtenu (Certificat d'Utilite en
France Ne80.21837 publié Nô2491 886 et ses correspondants à l'étranger ; voir aussi brevet américain N 4.377.234).
In order to overcome these drawbacks, it has already been proposed to create several compartments from the film of heat-shrinkable plastic by ensuring a connection, for welding or bonding, between the two free ends of the film and the film itself, according to a generatri ce or vertical line of the sleeve thus obtained (Certificate of Use in
France Ne80.21837 published Nô2491 886 and its correspondents abroad; see also US patent N 4,377,234).

Bien que cette solution permette généralement de résoudre le problème de la suppression destdefauts de déformation des textes et motifs imprimés, on est cependant confronté à une autre difficulté : en effet l'ensemble obtenu constitue rarement un pack rigide et les objets sont fréquemment amenés à se déplacerl'un par rapport à l'autre, dans leurs compartiments propres, du fait des efforts de traction, cisaillement ou autres au cours des diverses manipulations. Le cas est spécialement critique lorsqu'il s'agit d'emballer des séries d'objets commepar exemple des récipients - de forme cylindrique. Although this solution generally makes it possible to solve the problem of eliminating defects in deformation of printed texts and patterns, we are however faced with another difficulty: indeed the assembly obtained rarely constitutes a rigid pack and objects are frequently brought to move one relative to the other, in their own compartments, due to tensile, shear or other forces during various manipulations. The case is especially critical when it comes to packaging series of objects such as, for example, containers - of cylindrical shape.

I1 a maintenant été trouvé une solution efficace au groupement, en un emballage unitaire et selon un pack parfaitement rigide, de plusieurs objets de conformation identique ou différente introduits chacun dans un compartiment obtenu par soudure ou collage du film sur lui même. I1 has now been found an effective solution to the grouping, in a unitary packaging and according to a perfectly rigid pack, of several objects of identical or different conformation each introduced into a compartment obtained by welding or gluing the film on itself.

Conformément au procédé de l'invention,lR liaison unique entre chaque compartiment, selon une seule génératrice du manchon obtenu, est remplacée par au moins deux liaisons. Autrement dit, selon la définition générale du procédé, la soudure ou le collage du film sur lui-même, pour obtenir les multicompartiments, est effectue(e) selon au moins deux génératrices du manchon de façon à obtenir deux lignes distinctes de liaison verticale entre deuxcompartiments consécutifs. In accordance with the method of the invention, the single link between each compartment, according to a single generator of the sleeve obtained, is replaced by at least two links. In other words, according to the general definition of the process, the welding or the gluing of the film on itself, to obtain the multi-compartments, is carried out according to at least two generatrices of the sleeve so as to obtain two distinct lines of vertical connection between two consecutive compartments.

Afin de mieux faire comprendre l'invention et diverses variantes de réalisation, on donnera ci-après une description plus detail lée de modes d'exécution illustrés par les dessins schématiques annexes qui représentent
Figures 1 et 2 : l'illustration du procédé déjà connu, 1 plus
proche, pour la réalisation de compartiments multiples
Figure 3 : un mode de réalisation du procede de l'invention
Figure 4 : une variante d'exécution du procédé de la figure 3
Figure 5 : un autre mode d'application du procédé en cause
Les figures 1 et 2 se réferent à la technique déjà divulguée dans les brevets antérieurs rappelés ci-avant.Conformément à cette façon d'operer, le film plastique thermorétractable 1 (par exemple en chlorure de polyvinyle) est conformé en deux compartiments 2 et 3 par liaison entre elles et sur le film des deux extrémités libres de ce dernier confnrmément à la génératrice ou ligne unique XX'. Comme on l'a indiqué sur la figure 2 dans le cas, notamment d'objets ou réceptacles ronds, l'ensemble ou pack obtenu tend à se deformer par exemple selon les ftirces indiquees par les deux flerhes 4 et 5.
In order to better understand the invention and various variant embodiments, a more detailed description will be given below of embodiments illustrated by the accompanying schematic drawings which represent
Figures 1 and 2: the illustration of the already known process, 1 more
close, for the realization of multiple compartments
Figure 3: an embodiment of the method of the invention
Figure 4: an alternative embodiment of the method of Figure 3
Figure 5: Another mode of application of the process in question
Figures 1 and 2 refer to the technique already disclosed in the earlier patents mentioned above. In accordance with this way of operating, the heat-shrinkable plastic film 1 (for example made of polyvinyl chloride) is shaped into two compartments 2 and 3 by connection between them and on the film of the two free ends of the latter in accordance with the generator or single line XX '. As indicated in FIG. 2 in the case, in particular of round objects or receptacles, the assembly or pack obtained tends to deform for example according to the ftirces indicated by the two flers 4 and 5.

Selon le procéde de l'invention représenté sur les autres figures, on réalise impérativement, pour créer les deux compartiments ( titre illustratif et non limitatif) au moins deux lignes de liaison verti cale du film sur lui-même, selon les deux séries de génératrices YY' et
ZZ'. Par exemple, sur la figure 3, chaque extrémité libre du film I est repliée ou rabattue sur la partie continue et du même côté du film. Dans la variante de la figure 4, des liaisons des extrémités avec le film se font de part et d'autre de ce dernier et sont toujours, comne dans le cas de la figure 3, à une certaine distance l'une de l'autre. Enfin, conformément au mode de réalisation de la figure 5, les deux liaisons 6 et 7 sont entrecroisées, ce qui assure encore une meilleure rigidité au pack obtenu.
According to the method of the invention shown in the other figures, it is imperative to create, for creating the two compartments (illustrative and non-limiting title) at least two vertical connecting lines of the film on itself, according to the two series of generators YY 'and
ZZ '. For example, in Figure 3, each free end of the film I is folded or folded over the continuous part and on the same side of the film. In the variant of FIG. 4, connections of the ends with the film are made on either side of the latter and are always, as in the case of FIG. 3, at a certain distance from each other . Finally, in accordance with the embodiment of Figure 5, the two links 6 and 7 are intertwined, which further ensures better rigidity to the pack obtained.

Les liaisons susvisées s' effectuent, de manière connue en soi, par collage ou soudure et l'on peut prévoir, si désire, sur tout ou partie de la génératrice de liaison, une découpe pour le groupement de récipients de diverses hauteurs ou encore une ligne pointillée de prédécoupe.  The abovementioned connections are carried out, in a manner known per se, by gluing or welding and it is possible to provide, if desired, on all or part of the connection generator, a cutout for the grouping of containers of various heights or even a dotted precut line.

Par ailleurs, le procede de l'invention peut être mis en oeuvre pour la realisation d'emballages comportant de multiples compartiments qui sont deux à deux reliés par au moins deux lignes de soudure ou collage.  Furthermore, the method of the invention can be implemented for the production of packaging comprising multiple compartments which are two by two connected by at least two welding or bonding lines.
