Description

FLACON A POIGNEE LATERALE BOTTLE WITH SIDE HANDLE
La présente invention concerne l'emballage d'objets, et en particulier le conditionnement de produits de consommation tels que des produits alimentaires, chimiques, cosmétiques, ou pharmaceutiques, qui nécessitent en général une information du consommateur ou de l'utilisateur, ou encore d'autres informations d'ordre purement commercial.The present invention relates to the packaging of objects, and in particular the packaging of consumer products such as food, chemical, cosmetic, or pharmaceutical products, which generally require information from the consumer or the user, or else other purely commercial information.
Plus précisément, l'invention est relative à une enveloppe destinée à l'emballage d'un flacon à poignée latérale, du type constitué par un manchon en matière plastique thermorétractable apte à entourer étroitement le flacon après rétraction dudit manchon.More specifically, the invention relates to an envelope intended for the packaging of a bottle with lateral handle, of the type constituted by a sleeve made of heat-shrinkable plastic material capable of tightly surrounding the bottle after retraction of said sleeve.
On pourra se référer au document US-A-4 051 265 qui décrit une enveloppe thermorétractable destinée à protéger un bidon de liquide contre l'action de la lumière, et le passage des gaz ou des odeurs. Aucune mesure particulière n'est cependant prévue au niveau de la poignée du bidon.Reference may be made to document US-A-4,051,265 which describes a heat-shrinkable envelope intended to protect a container of liquid against the action of light, and the passage of gases or odors. No special measures are however planned at the handle of the container.
Les techniques de rétraction des manchons thermorétractables sur un objet sont maintenant parfaitement maîtrisées, mais des problèmes surgissent encore pour certains objets dont la géométrie complique la rétraction. C'est en particulier le cas pour des flacons à poignée latérale, car la poignée en saillie vient perturber la rétraction naturelle d'un manchon thermorétractable sur le corps du flacon. C'est pour cette raison que la technique utilisant des manchons thermorétractables n'a pour l'instant jamais été envisagée dans le cas de tels flacons à poignée latérale en saillie.The techniques for shrinking heat-shrinkable sleeves on an object are now perfectly mastered, but problems still arise for certain objects whose geometry complicates retraction. This is in particular the case for bottles with a lateral handle, since the protruding handle disturbs the natural retraction of a heat-shrinkable sleeve on the body of the bottle. It is for this reason that the technique using heat-shrink sleeves has so far never been envisaged in the case of such bottles with protruding side handle.
On sait réaliser des films en matière plastique thermorétractable, dont la mémoire est organisée pour produire un fort taux de rétreint dans le sens transversal, avec une faible rétraction longitudinale. On utilise pour cela des films mono-orientés dont la composition est parfaitement maîtrisée. De ce fait, on est capable de réaliser la rétraction d'un manchon cylindrique sur un flacon à poignée latérale, mais les parois du film définissant deux facettes sensiblement parallèles au niveau de l'ouverture de passage de la poignée interdisent l'utilisation de cette poignée pour la préhension de l 'objet. On pourrait naturellement envisager de pratiquer deux découpes sur le manchon après rétraction de celui-ci sur le flacon. Cette approche est par ex,emple illustrée dans le document EP-A-0 609 575, l'enveloppe thermorétractable présentant deux découpes à perforations dont le profil correspond à l'ouverture de passage de la poignée. Ceci oblige cependant à prévoir une opération de reprise incompatible avec une production à l'échelle industrielle .We know how to make films in heat-shrinkable plastic, whose memory is organized to produce a high rate of shrinking in the transverse direction, with low longitudinal retraction. Mono-oriented films are used for this, the composition of which is perfectly controlled. Therefore, we are able to carry out the retraction of a cylindrical sleeve on a bottle with lateral handle, but the walls of the film defining two substantially parallel facets at the opening of passage of the handle prohibit the use of this handle for gripping the object. One could naturally envisage making two cuts on the sleeve after retraction of the latter on the bottle. This approach is, for example, illustrated in document EP-A-0 609 575, the heat-shrinkable envelope having two perforated cutouts whose profile corresponds to the passage opening of the handle. This however requires the provision of a take-back operation incompatible with production on an industrial scale.
Des tentatives ont donc été effectuées en pratiquant deux découpes sur le manchon avant la mise en place de celui-ci, découpes dont le profil correspondrait à l'ouverture de préhension de la poignée. Une telle approche est illustrée dans le document EP-A-0 609 644. Cependant, on a constaté que les forces exercées circonférentiellement lors de la rétraction transversale du manchon provoquent des déchirures au niveau des découpes et/ou du ligament délimité par ces deux découpes et qui passent sur la face externe de la poignée. Les forces exercées circonférentiellement lors de la rétraction sont en effet très élevées, et toute présence de fente ou a fortiori d'ouverture de dimensionnement important affecte irrémédiablement l'intégrité mécanique des zones découpées lors de la rétraction du manchon sur l'objet.Attempts have therefore been made by making two cuts on the sleeve before the latter is put in place, cuts whose profile would correspond to the grip opening of the handle. Such an approach is illustrated in document EP-A-0 609 644. However, it has been found that the forces exerted circumferentially during the transverse retraction of the sleeve cause tears at the cutouts and / or the ligament delimited by these two cutouts. and which pass on the external face of the handle. The forces exerted circumferentially during the retraction are indeed very high, and any presence of a slot or a fortiori a large dimensioning opening irreparably affects the mechanical integrity of the areas cut during the retraction of the sleeve on the object.
L'invention vise précisément à résoudre ce problème, en concevant une enveloppe thermorétractable destinée à l'emballage d'un flacon à poignée latérale, qui ne présente pas les inconvénients ou limitations précités.The invention aims precisely to solve this problem, by designing a heat-shrinkable envelope intended for the packaging of a side handle bottle, which does not have the aforementioned drawbacks or limitations.
Ce problème est résolu conformément à l'invention grâce à une enveloppe destinée à l'emballage d'un flacon à poignée latérale, du type constitué par un manchon en matière plastique thermorétractable apte à entourer étroitement le flacon après rétraction dudit manchon, enveloppe dans laquelle le manchon présente deux découpes dont le profil correspond à l'ouverture de passage de la poignée, chaque découpe étant munie sur sa zone périphérique d'un élément rapporté de renfort solidaire de la paroi du manchon, lesdits éléments étant destinés à préserver l'intégrité de la zone des découpes en vis-à-vis lors de la rétraction du manchon entourant le flacon et sa poignée.This problem is solved in accordance with the invention thanks to an envelope intended for the packaging of a bottle with lateral handle, of the type constituted by a sleeve made of heat-shrinkable plastic material capable of tightly surrounding the bottle after retraction of said sleeve, envelope in which the sleeve has two cutouts, the profile of which corresponds to the opening for passage of the handle, each cutout being provided on its peripheral zone with an added reinforcing element secured to the wall of the sleeve, said elements being intended to preserve the integrity of the cut-out area opposite when the sleeve surrounding the bottle and its handle is retracted.
Ainsi, grâce à ces éléments rapportés de renfort, le profil des découpes est parfaitement préservé lors de la rétraction, jusqu'à la position finale du manchon qui adhère à la paroi extérieure du flacon, et ce même dans le cas de découpes de grandes dimensions.Thus, thanks to these added reinforcing elements, the profile of the cutouts is perfectly preserved during the retraction, up to the final position of the sleeve which adheres to the outer wall of the bottle, even in the case of large cutouts. .
Conformément à un premier mode de réalisation, l'élément rapporté de renfort associé à chaque découpe est un collier plat scellé à la paroi du manchon, dont le profil intérieur correspond au profil de la découpe. Le collier plat précité peut être unique pour chaque découpe, en étant scellé sur la face interne ou externe de la paroi du manchon, ou en variante être en double, avec un collier sur la face interne et un autre collier sur la face externe de la paroi. De préférence, chaque collier plat de renfort est en matériau essentiellement non rétractable à la température de rétraction de la paroi du manchon. Ceci permet de garantir la stabilité de la zone périphérique entourant chaque découpe. Conformément à un autre mode de réalisation, l'élément rapporté de renfort associé à chaque découpe est un opercule obturant la découpe et adhérant par sa périphérie à la zone périphérique de ladite découpe.According to a first embodiment, the reinforcing added element associated with each cut is a flat collar sealed to the wall of the sleeve, the internal profile of which corresponds to the profile of the cut. The aforementioned flat collar may be unique for each cut, by being sealed on the internal or external face of the wall of the sleeve, or alternatively be in duplicate, with a collar on the internal face and another collar on the external face of the wall. Preferably, each flat reinforcing collar is made of material which is essentially non-shrinkable at the shrinkage temperature of the wall of the sleeve. This guarantees the stability of the peripheral zone surrounding each cut. According to another embodiment, the reinforcing insert associated with each cut is a cover closing the cut and adhering by its periphery to the peripheral zone of said cut.
Comme précédemment pour le collier plat, l'opercule de renfort peut être unique pour chaque découpe, en adhérant à la face interne ou externe de la paroi du manchon, ou en variante être en double, avec un opercule sur la face interne et un autre opercule sur la face externe de la paroi du manchon. De préférence, chaque opercule de renfort est en matériau essentiellement non rétractable à la température de rétraction de la paroi du manchon.As previously for the flat collar, the reinforcement cover may be unique for each cut, by adhering to the internal or external face of the wall of the sleeve, or alternatively be in duplicate, with a cover on the internal face and another seal on the external face of the wall of the sleeve. Preferably, each reinforcement seal is made of material which is essentially non-shrinkable at the shrinkage temperature of the wall of the sleeve.
On pourra par ailleurs prévoir que chaque opercule de renfort est adhésivé à la paroi du manchon de façon à être pelable, avec de préférence une languette de préhension.It may also be provided that each reinforcement seal is adhesive to the wall of the sleeve so as to be peelable, preferably with a gripping tab.
En variante, chaque opercule de renfort pourra être adhésivé à la paroi du manchon de façon à être non pelable.As a variant, each reinforcement cover may be adhesive-bonded to the wall of the sleeve so as to be non-peelable.
Conformément à une autre variante, chaque opercule de renfort présente une ligne de prédécoupe dont le profil correspond à la prise en main du flacon par sa poignée. En particulier, on pourra prévoir que la zone centrale de l'opercule de renfort qui est à l'intérieur de la ligne de prédécoupe constitue un coupon de remise détachable. On pourra prévoir aussi que les opercules de renfort assurent une fonction de retenue de primes ou objets disposés dans le réceptacle qu'ils définissent avec la poignée du flacon.According to another variant, each reinforcement seal has a pre-cut line whose profile corresponds to the grip of the bottle by its handle. In particular, provision may be made for the central zone of the reinforcement cap which is inside the precut line to constitute a detachable remittance slip. Provision may also be made for the reinforcement lids to provide a function for retaining premiums or objects placed in the receptacle which they define with the handle of the bottle.
Conformément à une autre caractéristique, l'un au moins des opercules de renfort est au moins en partie imprimé .According to another characteristic, at least one of the reinforcement lids is at least partially printed.
Dans les techniques traditionnelles de pose de manchons sur des objets en défilement, les manchons sont détachés ou découpés d'une gaine continue enroulée à plat. Dans ce cas, il sera avantageux de prévoir que les deux découpes soient agencées symétriquement de part et d'autre d'un pli que présente le manchon dans son état non rétracté.In the traditional techniques of laying sleeves on moving objects, the sleeves are detached or cut from a continuous sheath wound flat. In this case, it will be advantageous to provide that both cutouts are arranged symmetrically on either side of a fold that the sleeve has in its non-retracted state.
Dans le cas d'un flacon à poignée latérale en saillie du corps du flacon on pourra prévoir une autre variante d'enveloppe selon l'invention, selon laquelle le manchon présente une découpe unique dont le profil correspond au passage de la poignée en saillie, la découpe étant munie sur sa zone périphérique d'un collier plat rapporté de renfort scellé à la paroi du manchon et dont le profil intérieur correspond au profil de ladite découpe, ledit collier étant destiné à préserver l'intégrité de la zone de la découpe lors de la rétraction du manchon entourant le flacon en laissant passer la poignée en saillie.In the case of a bottle with a lateral handle protruding from the body of the bottle, it is possible to provide another variant of an envelope according to the invention, according to which the sleeve has a single cutout whose profile corresponds to the passage of the protruding handle, the cutout being provided on its peripheral zone with a flat collar attached to the reinforcement sealed to the wall of the sleeve and whose internal profile corresponds to the profile of said cutout, said collar being intended to preserve the integrity of the cutout zone during the shrinkage of the sleeve surrounding the bottle, allowing the protruding handle to pass.
Dans cette variante, le manchon enjambe la poignée qui passe dans l'ouverture définie par la découpe, contrairement au mode de réalisation précédent où le manchon rétracté restait en appui sur la facette externe de la poignée du flacon.In this variant, the sleeve spans the handle which passes through the opening defined by the cut, in contrast to the previous embodiment where the retracted sleeve remained in abutment on the external facet of the handle of the bottle.
Comme précédemment, le collier plat pourra être unique, en étant scellé sur la face interne ou externe de la paroi du manchon, ou en variante être en double, avec un collier sur la face interne et un autre collier sur la face externe de la paroi du manchon.

Provision may also be made for the or each flat collar to be made of material which is essentially non-shrinkable at the shrinkage temperature of the wall of the sleeve.

Sur la figure 1, on distingue un flacon 1 dont le corps 2 présente une poignée latérale 3 qui se raccorde au contour extérieur du corps de flacon. L'ouverture de passage de la poignée est notée 4. Pour réaliser l'emballage d'un tel flacon à poignée latérale, en utilisant une technique de manchon en matière plastique thermorétractable apte à entourer étroitement le flacon après rétraction dudit manchon, on utilise une enveloppe 100 qui est représentée sur la figure 1 à l'état non rétracté.In Figure 1, there is a bottle 1 whose body 2 has a side handle 3 which is connected to the outer contour of the bottle body. The opening for passage of the handle is noted 4. To make the packaging of such a bottle with lateral handle, using a sleeve technique made of heat-shrinkable plastic capable of tightly surrounding the bottle after retraction of said sleeve, a envelope 100 which is shown in Figure 1 in the non-shrunk state.
L'enveloppe 100 est essentiellement constituée par un manchon 101 dont les parois sont fermées sur elles-mêmes selon une ligne de scellage 102 ainsi que cela est classique dans le domaine concerné.The envelope 100 is essentially constituted by a sleeve 101, the walls of which are closed on themselves along a sealing line 102, as is conventional in the field concerned.
Conformément à l'invention, le manchon 101 présente deux découpes 103 dont le profil correspond à l'ouverture de passage 4 de la poignée du flacon, et chaque découpe 103 est munie sur sa zone périphérique d'un élément rapporté de renfort 104 solidaire de la paroi du manchon, lesdits éléments étant destinés à préserver l'intégrité de la zone des découpes en vis-à-vis lors de la rétraction du manchon entourant le flacon et sa poignée. Sur la figure 1, l'élément rapporté de renfort associé à chaque découpe 103 est un collier plat 104 qui est scellé à la paroi du manchon 101. Le profil intérieur du collier plat 104 correspond au profil de la découpe 103.According to the invention, the sleeve 101 has two cutouts 103, the profile of which corresponds to the passage opening 4 of the handle of the bottle, and each cutout 103 is provided in its peripheral zone with an added reinforcing element 104 secured to the wall of the sleeve, said elements being intended to preserve the integrity of the area of the cut-outs facing each other during the retraction of the sleeve surrounding the bottle and its handle. In FIG. 1, the reinforcing insert associated with each cutout 103 is a flat collar 104 which is sealed to the wall of the sleeve 101. The internal profile of the flat collar 104 corresponds to the profile of the cutout 103.
Lorsque le manchon 101 est enfilé sur le flacon 1, et que l'ensemble passe dans un tunnel de rétraction, la paroi du manchon se rétracte transversalement, et les deux découpes 103 viennent se placer de part et d'autre de l'ouverture de passage 4, laissant ainsi le libre passage pour la préhension du flacon par sa poignée. Grâce à la présence des colliers plats de renfort 104, l'intégrité de la zone des découpes est préservée, c'est-à-dire que le profil des découpes garde sa géométrie initiale, et la zone périphérique de chaque découpe reste plate, sans déchirures ni frisures. Le résultat obtenu est illustré sur la figure 2.When the sleeve 101 is threaded onto the bottle 1, and the assembly passes through a retraction tunnel, the wall of the sleeve retracts transversely, and the two cutouts 103 are placed on either side of the opening of passage 4, thus leaving free passage for gripping the bottle by its handle. Thanks to the presence of the reinforcing flat collars 104, the integrity of the cutout area is preserved, that is to say that the cutout profile keeps its initial geometry, and the peripheral area of each cutout remains flat, without tears or crimps. The result obtained is illustrated in FIG. 2.
Comme cela est mieux visible sur les coupes de la figure 3, on peut avoir plusieurs agencements différents pour le renforcement des découpes 103 :As is better visible on the sections of FIG. 3, there can be several different arrangements for reinforcing the cuts 103:
- en a) , les colliers plats 104 sont uniques pour chaque découpe 103 et ils sont scellés sur la face interne de la paroi du manchon 101,in a), the flat collars 104 are unique for each cutout 103 and they are sealed on the internal face of the wall of the sleeve 101,
- en b) , les colliers plats 104 sont encore uniques pour chaque découpe 103, mais ils sont scellés sur la face externe de la paroi du manchon 101, - en c) , chaque collier plat 104 est en double, avec un collier sur la face interne et un autre collier sur la face externe de la paroi du manchon 101.- in b), the flat collars 104 are still unique for each cut 103, but they are sealed on the external face of the wall of the sleeve 101, - in c), each flat collar 104 is duplicated, with a collar on the internal face and another collar on the external face of the wall of the sleeve 101.
De préférence, chaque collier plat de renfort 104 sera réalisé en matériau essentiellement non rétractable à la température de rétraction de la paroi du manchon 101. Ceci apparaît hautement désirable pour obtenir un effet de renfort optimal. On utilisera en général une matière plastique, qui est alors amorphe pour ne pas offrir de possibilité de rétraction sous l'effet de la chaleur. La fixation de chaque collier de renfort 104 à la paroi du manchon est réalisée par scellage, et cette solidarisation reste invariable lors de la rétraction du manchon.Preferably, each flat reinforcement collar 104 will be made of a material that is essentially non-retractable at the retraction temperature of the wall of the sleeve 101. This appears highly desirable in order to obtain an optimal reinforcement effect. In general, a plastic material will be used, which is then amorphous so as not to offer the possibility of shrinking under the effect of heat. The fixing of each reinforcing collar 104 to the wall of the sleeve is carried out by sealing, and this joining remains invariable during the retraction of the sleeve.
Conformément à une variante de réalisation illustrée à la figure 4, il est possible de prévoir que l'élément rapporté de renfort, au lieu d'être un collier plat dont le profil intérieur correspond au profil de la découpe, est constitué par un opercule venant obturer complètement chaque découpe.In accordance with an alternative embodiment illustrated in FIG. 4, it is possible to provide that the added reinforcing element, instead of being a flat collar whose internal profile corresponds to the profile of the cutout, is constituted by a cover coming from completely seal each cut.
On utilise ainsi une enveloppe 200, essentiellement constituée par un manchon en matière plastique thermorétractable 201, avec sa ligne de scellage 202 selon une génératrice du manchon. L'élément rapporté de renfort associé à chacune des deux découpes 203 est alors un opercule 204 obturant la découpe et adhérant par sa périphérie à la zone périphérique de ladite découpe. L'opercule de renfort 204, qui est solidaire par sa zone périphérique 205 à la paroi du manchon, constitue alors une fenêtre de fermeture obturant totalement la découpe associée. Après rétraction, on obtient le résultat illustré sur la figure 5.An envelope 200 is thus used, essentially constituted by a plastic sleeve heat-shrinkable 201, with its sealing line 202 along a generatrix of the sleeve. The reinforcing insert associated with each of the two cutouts 203 is then a cover 204 closing the cutout and adhering by its periphery to the peripheral zone of said cutout. The reinforcement seal 204, which is integral by its peripheral zone 205 with the wall of the sleeve, then constitutes a closing window completely closing the associated cutout. After retraction, the result illustrated in FIG. 5 is obtained.
Comme cela est illustré sur la figure 6, l'opercule de renfort 204 peut être unique pour chaque découpe 203, et adhérer à la face interne comme représenté en a) ou externe comme représenté en b) de la paroi du manchon 201. En c) , on a illustré le cas où l'opercule de renfort 204 est en double, avec un opercule sur la face interne et un autre opercule sur la face externe de la paroi du manchon 201.As illustrated in FIG. 6, the reinforcement cover 204 can be unique for each cut 203, and adhere to the internal face as shown in a) or the external face as shown in b) of the wall of the sleeve 201. At c ), the case has been illustrated where the reinforcement cover 204 is in duplicate, with a cover on the internal face and another cover on the external face of the wall of the sleeve 201.
Comme précédemment, chaque opercule de renfort 204 sera de préférence réalisé en matériau essentiellement non rétractable à la température de rétraction de la paroi du manchon 201. Ainsi, la périphérie de l'opercule de renfort 204 assure la même fonction que le collier plat précité, c'est-à-dire garantit l'intégrité de la zone des découpes en vis-à-vis lors de la rétraction du manchon entourant le flacon et sa poignée.As before, each reinforcement cover 204 will preferably be made of material which is essentially non-shrinkable at the temperature of shrinkage of the wall of the sleeve 201. Thus, the periphery of the reinforcement cover 204 performs the same function as the above-mentioned flat collar, that is to say, guarantees the integrity of the cut-out area facing each other during the retraction of the sleeve surrounding the bottle and its handle.
On pourra en outre prévoir que chaque opercule de renfort 204 est adhésivé à la paroi du manchon 201 de façon à être pelable ou non.Provision may also be made for each reinforcement seal 204 to be adhesive-bonded to the wall of the sleeve 201 so as to be peelable or not.
Sur la figure 7, on a représenté ainsi une enveloppe 200 dont le manchon est équipé de deux opercules de renfort 204 qui sont pelables, chaque opercule de renfort étant équipé d'une languette de préhension 206. Ainsi, en tirant la languette de préhension 206, il est aisé de dégager chaque opercule de renfort 204, et de libérer l'ouverture de passage de la poignée. Comme illustré sur la figure 7, on pourra en outre prévoir que les opercules de renfort 204 assurent une fonction supplémentaire de retenue de primes ou objets 51 disposés dans le réceptacle 50 qu'ils définissent avec la poignée du flacon.In FIG. 7, an envelope 200 is thus represented, the sleeve of which is equipped with two reinforcement lids 204 which are peelable, each reinforcement lid being equipped with a gripping tab 206. Thus, by pulling the gripping tab 206 , it is easy to disengage each reinforcement cover 204, and to release the passage opening of the handle. As illustrated in FIG. 7, provision may also be made for the reinforcement lids 204 to perform an additional function of retaining premiums or objects 51 arranged in the receptacle 50 which they define with the handle of the bottle.
Sur la figure 8, on a illustré une autre variante, dans laquelle chaque opercule de renfort 204 est non pelable, et présente une ligne de prédécoupe 207 dont le profil correspond à la prise en main du flacon par sa poignée. Le dégagement de la zone centrale 208 de l'opercule de renfort 204, effectué de chaque côté de la poignée du flacon, permet de dégager l'ouverture de passage de la poignée.In FIG. 8, another variant has been illustrated, in which each reinforcement cover 204 is non-peelable, and has a pre-cut line 207 whose profile corresponds to the grip of the bottle by its handle. The release of the central zone 208 of the reinforcement cap 204, carried out on each side of the handle of the bottle, makes it possible to clear the opening for passage of the handle.
On pourra éventuellement profiter de cette disposition pour prévoir que la zone centrale 208 de l'opercule de renfort 204, qui est à l'intérieur de la ligne de prédécoupe 207, constitue un coupon de remise détachable. Ce coupon pourra éventuellement être imprimé, comme cela a été schématisé ici par les lettres A, B, C. Sur la figure 8, on a illustré un tel coupon détaché qui est utilisable comme bon de remise au moment de l'acte d'achat. La ligne de prédécoupe 207 sera naturellement prévue avec des perforations telles que, après enlèvement de la zone centrale formant coupon 208, les bords de la partie découpée, qui correspondent au passage de la main pour saisir le flacon par sa poignée, ne présentent pas d'aspérités blessantes indésirables.We could possibly take advantage of this arrangement to provide that the central zone 208 of the reinforcement cover 204, which is inside the precut line 207, constitutes a detachable discount coupon. This coupon could possibly be printed, as shown here by the letters A, B, C. In FIG. 8, there is illustrated such a detached coupon which can be used as a discount coupon at the time of the act of purchase. . The pre-cut line 207 will naturally be provided with perforations such that, after removal of the central zone forming a coupon 208, the edges of the cut part, which correspond to the passage of the hand to grasp the bottle by its handle, do not show any '' unwanted offensive asperities.
L'un au moins des opercules de renfort 204 pourra être au moins en partie imprimé. Sur la figure 8, on a juste illustré la zone centrale 208 formant coupon qui est imprimée .At least one of the reinforcement lids 204 may be at least partially printed. In FIG. 8, we have just illustrated the central zone 208 forming a coupon which is printed.
Les manchons thermorétractables classiquement utilisés dans le domaine de l'emballage sont en général détachés ou découpés d'une gaine continue enroulée à plat. Dans ce cas, les tronçons séparés de la gaine continue présentent deux plis, qui s'estompent lors de la rétraction du manchon sur l'objet concerné. Pour la première variante, ces plis sont référés 109, 110, et pour la deuxième variante 209, 210. Comme illustré ici, on a prévu que les deux découpes 103, 203 sont agencées symétriquement de part et d'autre d'un pli respectivement 110, 210 que présente le manchon 101, 201 dans son état non rétracté. Grâce à cette disposition, les découpes sont en regard l'une de l'autre lorsque le manchon est à plat, ce qui facilite considérablement leur réalisation.The heat shrinkable sleeves conventionally used in the packaging field are generally detached or cut from a continuous sheath wound flat. In this case, the separate sections of the sheath continues have two folds, which fade during the retraction of the sleeve on the object concerned. For the first variant, these folds are referenced 109, 110, and for the second variant 209, 210. As illustrated here, provision has been made for the two cutouts 103, 203 to be arranged symmetrically on either side of a fold respectively 110, 210 presented by the sleeve 101, 201 in its non-retracted state. Thanks to this arrangement, the cutouts are facing one another when the sleeve is flat, which considerably facilitates their production.
Lorsque l'objet à emballer est un flacon à poignée latérale en saillie du corps de flacon, on peut envisager une autre variante de l'enveloppe thermorétractable de l'invention. Cette variante va être illustrée en référence aux figures 9 à 11.When the object to be packaged is a bottle with a lateral handle projecting from the bottle body, another variant of the heat-shrinkable envelope of the invention can be envisaged. This variant will be illustrated with reference to FIGS. 9 to 11.
Sur la figure 9, on distingue un flacon l', dont le corps 2' présente une poignée latérale 3' en saillie du corps, l'ouverture de passage de la poignée étant notée 4'. Bien que l'on puisse en théorie utiliser une enveloppe du type précédemment décrit, on pourra envisager une variante selon laquelle l'enveloppe 300, essentiellement constituée par un manchon 301 à ligne de scellage 302, présente une découpe unique 303 dont le profil correspond au passage de la poignée en saillie. Dans ce cas, la découpe unique 303 est munie sur sa zone périphérique d'un collier plat rapporté de renfort 304 scellé à la paroi du manchon et dont le profil intérieur correspond au profil de ladite découpe. Comme pour les colliers plats de renfort 104 précédemment décrits, le collier plat 304 est destiné à préserver l'intégrité de la zone de la découpe unique lors de la rétraction du manchon entourant le flacon, mais ici en laissant passer la poignée en saillie. Le résultat obtenu après rétraction est illustré sur la figure 10.In FIG. 9, there is a bottle 1 ′, the body 2 ′ of which has a lateral handle 3 ′ projecting from the body, the opening for passage of the handle being denoted 4 ′. Although it is theoretically possible to use an envelope of the type described above, a variant could be envisaged according to which the envelope 300, essentially constituted by a sleeve 301 with a sealing line 302, has a single cut 303 whose profile corresponds to passage of the protruding handle. In this case, the single cutout 303 is provided on its peripheral zone with an attached flat collar of reinforcement 304 sealed to the wall of the sleeve and whose internal profile corresponds to the profile of said cutout. As with the reinforcement flat collars 104 previously described, the flat collar 304 is intended to preserve the integrity of the area of the single cutout during the retraction of the sleeve surrounding the bottle, but here by letting the protruding handle pass. The result obtained after retraction is illustrated in FIG. 10.
Comme illustré sur la figure 11, on retrouve différents types d'agencements envisageables pour le collier plat 304, avec en a) un scellage sur la face interne de la paroi du manchon 301, en b) un scellage sur la face externe de la paroi du manchon 301, et en c) un agencement double, avec un collier sur la face interne et un autre collier sur la face externe de la paroi du manchon 301.As illustrated in FIG. 11, there are different types of possible arrangements for the flat collar 304, with in a) a seal on the internal face of the wall of the sleeve 301, in b) a seal on the external face of the wall of the sleeve 301, and in c) a double arrangement, with a collar on the internal face and another collar on the external face of the wall of the sleeve 301.
Comme précédemment, le ou chaque collier plat 304 sera de préférence réalisé en matériau essentiellement non rétractable à la température de rétraction de la paroi du manchon 301.As before, the or each flat collar 304 will preferably be made of material which is essentially non-shrinkable at the shrinking temperature of the wall of the sleeve 301.
La découpe unique 303 est également centrée par rapport à un pli 310 que présente le manchon -301 provenant d'une gaine continue enroulée à plat.The single cutout 303 is also centered with respect to a fold 310 presented by the sleeve -301 coming from a continuous sheath wound flat.
Dans tous les cas, il sera avantageux de prévoir de disposer les flacons revêtus de leur manchon dans une disposition telle que les plis soient dans le plan vertical médian du tunnel de rétraction, le flacon avec sa poignée étant calé sur ce plan vertical. Grâce à cette disposition, avec un défilement des flacons présentant une ouverture des poignées face au défilement des convoyeurs, on évite toute exposition excessive de la zone des découpes à l'action des éléments chauffants, qui sont en général des éléments infrarouges .In all cases, it will be advantageous to provide the vials coated with their sleeve in an arrangement such that the folds are in the vertical median plane of the retraction tunnel, the vial with its handle being wedged on this vertical plane. Thanks to this arrangement, with a scrolling of the bottles having an opening of the handles facing the scrolling of the conveyors, any excessive exposure of the cutout area to the action of the heating elements, which are generally infrared elements, is avoided.
Pour chacun des modes de réalisation qui vient d'être décrit, la réalisation des enveloppes conforme à l'invention est compatible avec une pose automatique. Les agencements à colliers de renfort ou opercules d'obturation sont adaptables en fonction "de la forme de la poignée et de la forme du flacon, et aussi aux différents desiderata relatifs à l'impression ou la non-impression.For each of the embodiments which have just been described, the production of the envelopes according to the invention is compatible with automatic installation. The arrangements with reinforcement collars or sealing lids are adaptable as a function of " the shape of the handle and the shape of the bottle, and also to the various requirements relating to printing or non-printing.
Si on utilise un opercule pelable, la partie auto- adhésive doit utiliser un adhésif avec une colle spéciale qui résiste à la température du retreint sans se ramollir, c'est-à-dire vraisemblablement une colle dont le point de ramollissement se situe au-dessus de 140°C. D'une façon générale, on prévoira que la rigidité de la structure du matériau substitutif du manchon doit être suffisamment rigide pour résister aux contraintes imposées par les forces développées lors du rétreint transversal.If a peelable seal is used, the self-adhesive part must use an adhesive with a special glue which resists the temperature of the shrinkage without softening, i.e. probably a glue whose softening point is located above 140 ° C. In general, it will be provided that the rigidity of the structure of the substitute material of the sleeve must be rigid enough to withstand the stresses imposed by the forces developed during the transverse constriction.
Bien qu'il soit intéressant d'utiliser des matières plastiques amorphes, n'offrant pas de possibilité de rétraction sous l'effet de la chaleur, on pourra en variante envisager des supports de base en papier ou multicouc es .Although it is advantageous to use amorphous plastics, not offering the possibility of shrinking under the effect of heat, we can alternatively consider basic supports made of paper or multilayer.
Enfin, on pourra dans certains cas, lorsque la géométrie du corps de flacon présente une fσrte conicité, prévoir que le manchon, une fois enfilé sur le flacon, et avant rétraction, soit collé à la base du flacon. Le manchon, déjà équipé de ses colliers, ou opercules, est alors parfaitement positionné sur le flacon, et l'on écarte alors tout risque de glissement vers le haut lors de la rétraction du manchon qui serait due à la forme très incurvée du flacon. L'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits, mais englobe au contraire toute variante reprenant, avec des moyens équivalents, les caractéristiques essentielles énoncées plus haut . Finally, in certain cases, when the geometry of the bottle body has a conical shape, it will be possible to provide that the sleeve, once threaded on the bottle, and before shrinking, is glued to the base of the bottle. The sleeve, already fitted with its collars, or lids, is then perfectly positioned on the bottle, and any risk of sliding upwards during the retraction of the sleeve which is due to the very curved shape of the bottle is therefore eliminated. The invention is not limited to the embodiments which have just been described, but on the contrary encompasses any variant incorporating, with equivalent means, the essential characteristics set out above.
