Definitions
- the invention relates to a packaging for packaging in shrinkable plastic film of at least one object, of the type comprising a packaging body of a semi-rigid material such as cardboard or corrugated cardboard and a film of a shrinkable plastic material. , which is integral with said packaging body and holds the object or objects therein by enclosing them, after retraction of said film.
- Such packaging arouses great interest among users, because it allows the grouping, within the same packaging body, of objects or batches of objects of different volumes, less than the internal volume of the packaging body, which are held firmly in position against the inner face of the bottom thereof.
- the Applicant also proposes an original method for placing the plastic sheet between the bottom flaps, but this process is relatively costly for the user, since the plastic film cannot be rendered secured to the packaging body only during the setting up of the American box.
- the present invention aims to remedy this drawback by proposing a packaging of the type defined above, other than an American box, in which a single film of shrinkable plastic material is pinched between parts of the bottom of the packaging body at the assembled state, thus ensuring, after retraction, excellent retention in position of the packaged objects, while making it possible to deliver the packaging flat to the user, with the plastic film glued against the packaging body, thus avoiding the use of expensive materials for its installation, when this packaging body is placed in volume.
- the subject of the invention is a packaging from a single blank for the packaging of at least one object, of the type comprising a packaging body made of a semi-rigid material such as cardboard or corrugated cardboard. , and an uninterrupted film of a shrinkable plastic, which is integral with said body and is intended, after retraction, to hold said object in position therein, said packaging body comprising a rectangular or square external bottom, constituted by a single panel attached by a fold line to two first parallel walls, the shrinkable plastic film extending on the bottom and on said first walls parallel to two second parallel walls or to flaps internally lining these second walls, this packaging being characterized by that said film is laminated against the internal face of the bottom and locked in the glued position by pinching between the bottom and flaps which internally double this bottom and are adjoined by fold lines to said second walls or to flaps internally lining these second walls .
- the shrink film is therefore held in position, on the one hand, by gluing against the bottom, on the other hand, by the flaps which internally double this bottom and on which the conditioned objects rest.
- This obtains a locking in position of this film and of the objects which it encloses, which allows it not to move in the event of impacts or violent movements of the packaging during handling, even if the object or objects packaged are of a large mass and / or a volume much less than the internal volume of the packaging.
- the packaging body may be of a type known per se, which will further facilitate its setting in volume for users .
- the plastic film retractable may be made temporarily secured, by glue dots, said first walls adjoining the bottom or flaps extending these walls, to facilitate the volume setting of the packaging body and its filling.
- the film is then simply detached from these first walls or from these flaps to be folded, at its two ends, onto the conditioned objects, before proceeding to the retraction phase.
- the shrinkable plastic film may extend laterally or not on the second walls or on the flaps which line these walls.
- Figure 7 is a view of a blank for producing a fourth package according to the invention.
- the packaging shown in FIGS. 1 and 2 comprises a packaging body of a known type, of generally parallelepipedal shape, comprising a bottom 1, to which are adjoined by fold lines or upsets of the longitudinal walls or first walls 2 and 3.
- transverse walls 4 adjoin the ends of the longitudinal wall (second walls) 2.
- a flap 5 adjoining these walls by a fold line, comes double the bottom in mounted position.
- a flap 6, articulated by fold lines, is folded inside the packaging in the assembled position to internally double the associated wall 4.
- a tongue 7 of these flaps 6 is engaged in a cutout 8 of the flap 5 corresponding during assembly.
- the longitudinal wall 3 is extended laterally by flaps 9 which, in the assembled position, are engaged between the walls 4 and the flaps 6.
- a cover 10 is articulated by a fold line at the upper part of the longitudinal wall 2 and is extended by a panel 11, which, in the closed position, is applied against the external face of the wall 3.
- This panel 11 is extended laterally by flaps 12 having a curved edge 13, which allows them to be engaged between the flaps 9 and the wall 4 during the closing phase.
- a film of shrinkable material 14 which in this case is less than the length of the walls 2 and 3, is laminated against the bottom 1 by lines of glue 15, and s 'extends parallel to the transverse walls 4, without overlapping the flaps 6 internally lining these walls.
- the film 14 may advantageously be made temporarily attached, on the blank of cardboard, to the first walls 2 and 3 and possibly the cover 10, to using simple dots of glue 16. After mounting the packaging and putting it in place of the objects to be packaged, it will suffice to detach the film 14 from the walls 2 and 3 and from the cover 10 to fold its ends onto the objects and to retract it before closing the packaging.
- FIGS 3 and 4 show another form of implementation of the invention, different from the previous one, but having very exactly the same advantages.
- This packaging also comprises a packaging body of a known type of generally parallelepiped shape, which comprises a bottom 21 adjoining two longitudinal walls or first walls 22 and 23. At the wall 22 are adjoined laterally two flaps 24, intended to form the transverse walls. These are lined internally by two flaps 25 laterally extending the longitudinal wall 23. At the base of these flaps 25 is connected by a fold line a panel 26, of dimension less than or less than half the length of the bottom 21, which internally doubles it in the mounted position.
- each of the walls 22 is hinged by a fold line a panel 27, of dimension equal to or greater than half that of the bottom 1 and intended to form a closure element of the packaging body at the upper part of it.
- the external walls or second walls 24, on the one hand, and the flaps 25 which double them internally, on the other hand, are joined by bellows 20 to the panels 27.
- the bellows 28 are folded back flat against the internal face of the flaps 25, which they thus maintain applied against the walls 24.
- the walls 24 and the flaps 25 can, moreover, be made integral by gluing or stapling.
- a plastic film 29 is laminated against the bottom 21 by lines of glue 30 and extends parallel to the flaps 25 internally lining the transverse walls 24 without overflowing on these flaps. It is thus possible to deliver to the users the cut and repressed blank, such as shown in Figure 4, with the film 29, and the packaging body can be mounted in the usual way, without expensive special devices, by pinching the part of the film glued on the bottom between it and the flaps 26, with great film fixing security.
- the flaps 26 have a cutout 31 in a corner in order to be able to access the film 29, after assembly, and release it if necessary.
- glue dots 32 make it possible to temporarily secure, on the starting blank, the film 29 and the panels 27 and / or the first walls 22, 23, to facilitate mounting of the packaging and the placement of the objects to be packaged.
- the ends of the film 29 are then detached from the panels 27 and the walls 22 and 23, folded over the objects, and subjected to a shrinking phase.
- the panels 27 can then be folded down to close the packaging, and joined together by a gummed strip or by gluing in case of overlapping of the panels.
- the body of this packaging comprises a rectangular external bottom 41, connected to two parallel longitudinal walls or first walls 42 and 43.
- a cover 44 At the upper part of the wall 42 is hinged a cover 44, capable of being folded down parallel to the bottom for closing the packaging, a tongue 45, provided at the upper part of the wall 43 which engages in this position in a cutout 46 of the cover.
- articulated flaps 47 able to be arranged perpendicular to this wall, to be pinched between panels 48, adjoining the ends of the wall 42 and forming the external transverse wall or second wall of the packaging, and flaps 49, adjoining the upper part of these transverse walls 48 and folded towards the bottom.
- flaps 48 At the base of the flaps 48 are hinged flaps 50, which double the bottom 41 inside the packaging body, with a partial overlap of the flaps. Cut-outs 51, formed in these flaps and possibly in the bottom, allow the flaps 49 to be locked in position by engaging a tab 52 of these flaps.
- Tabs 54 cut in a portion of the bottom and adjoining the flaps 50, are retracted by folding below these and pinched between them and the bottom in the assembled position of the packaging. The role of these retractable tabs will be explained below.
- a film 55 of shrinkable plastic material is laminated against the bottom 41 by lines of glue 56.
- the film 55 is temporarily secured to the cover and the walls 42 and 43 by dots of glue 57.
- the film extends parallel to the transverse walls 40, but has a width greater than the length of the longitudinal walls 42 and 43, so that it extends laterally, on the starting blank, on the transverse walls 40.
- this film is also pinched not only between the bottom 41 and the flaps 50, but also between the walls 40 and the flaps 47.
- the protruding parts of the film are however folded at 50 on these elements of the packaging body.
- Cut-outs are provided for this purpose in the flaps 50 lining the bottom, in order to be able to access the film in the corners, to release it, the retractable tabs 54 are intended to facilitate the mounting of the packaging and the positioning of the film 55, on which they slide at the bottom.
- Such packaging is intended for packaging objects whose volume is close to the internal volume of packaging. It is, in fact, possible to fold the folded parts 58 of the plastic film, on the side faces of such an object, adjacent to the flaps 49, so that after the retraction phase, the object is thus kept perfectly as follows all of its side faces.
- FIG. 7 This packaging is however of a relatively complex design, so the Applicant has developed a fourth embodiment of the invention which is illustrated in FIG. 7.
- This embodiment of the invention with a film extending laterally, therefore lends itself to assembly as easy as the embodiment of FIGS. 1 and 2.
- the invention therefore provides users with packaging that is easy to assemble with conventional means, which can be delivered to them with the shrinkable plastic film integral with the blank from which the packaging body will be derived, and which offers great security of holding the shrink film and, therefore, the packaged objects.

Description
L'invention concerne un emballage pour le conditionnement sous film plastique rétractable d'au moins un objet, du type comprenant un corps d'emballage en une matière semi-rigide telle que le carton ou le carton ondulé et un film en une matière plastique rétractable, qui est solidaire dudit corps d'emballage et y maintient le ou les objets en les enserrant, après rétraction dudit film.The invention relates to a packaging for packaging in shrinkable plastic film of at least one object, of the type comprising a packaging body of a semi-rigid material such as cardboard or corrugated cardboard and a film of a shrinkable plastic material. , which is integral with said packaging body and holds the object or objects therein by enclosing them, after retraction of said film.
De tels emballages suscitent un très grand intérêt auprès des utilisateurs, car ils permettent le regroupement au sein d'un même corps d'emballage d'objets ou de lots d'objets de volumes différents, inférieurs au volume interne du corps d'emballage, qui sont maintenus fermement en position contre la face intérieure du fond de celui-ci.Such packaging arouses great interest among users, because it allows the grouping, within the same packaging body, of objects or batches of objects of different volumes, less than the internal volume of the packaging body, which are held firmly in position against the inner face of the bottom thereof.
On a proposé de nombreuses variantes de tels emballages.Many variants of such packages have been proposed.
On a ainsi suggéré de coller deux feuilles de matière plastique rétractable contre deux parois latérales opposées du corps d'emballage, à l'intérieur ou à l'extérieur de ces parois, et de rabattre ces feuilles contre les objets conditionnés, pour les réunir entre elles au cours de l'opération de rétraction. Ces emballages sont cependant d'une utilisation peu pratique, du fait de l'emploi de deux feuilles de matière plastique, qui compliquent les opérations de mise en volume du corps d'emballage, généralement livré à plat aux utilisateurs, et les opérations de conditionnement.It has thus been suggested to glue two sheets of shrinkable plastic material against two opposite side walls of the packaging body, inside or outside of these walls, and to fold these sheets against the packaged objects, to bring them together them during the retraction operation. These packages are however of impractical use, due to the use of two plastic sheets, which complicate the operations of setting up the volume of the packaging body, generally delivered flat to the users, and the packaging operations. .
Pour remédier à cet inconvénient, la Demanderesse a proposé, dans son brevet français N° 2 506 722, de coller une unique feuille de matière plastique contre les faces internes du fond et de deux parois latérales opposées du corps d'emballage.To remedy this drawback, the Applicant has proposed, in its French patent No. 2,506,722, to glue a single sheet of plastic material against the internal faces of the bottom and of two opposite side walls of the packaging body.
Cette feuille de matière plastique risque toutefois de se décoller du corps de l'emballage au cours des opérations de manutention et sous les chocs subis, lorsque l'emballage plein est déplacé, en particulier si les objets conditionnés sont lourds. Aussi la Demanderesse a-t-elle proposé, dans son brevet français N° 2 567 101, d'assujettir la feuille plastique au corps d'emballage, lorsque celui-ci est constitué par une caisse dite américaine, en pinçant cette feuille de plastique entre les volets internes et les volets externes qui constituent le fond, ces volets dits aussi "rabats" étant attenants, respectivement, à deux jeux de parois latérales parallèles.This sheet of plastic material, however, may come off the body of the packaging during handling operations and under the shocks suffered, when the full packaging is moved, especially if the packaged items are heavy. The Applicant has therefore proposed, in its French patent No. 2,567,101, to subject the plastic sheet to the packaging body, when the latter is constituted by a so-called American box, by pinching this plastic sheet between the internal flaps and the external flaps which constitute the bottom, these flaps also called "flaps" being adjacent, respectively, to two sets of parallel side walls.
Dans le même brevet, la Demanderesse propose en outre un procédé original de mise en place de la feuille de matière plastique entre les rabats du fond, mais ce procédé est relativement coûteux pour l'utilisateur, puisque le film de matière plastique ne peut être rendu solidaire du corps d'emballage qu'au cours de la mise en volume de la caisse américaine.In the same patent, the Applicant also proposes an original method for placing the plastic sheet between the bottom flaps, but this process is relatively costly for the user, since the plastic film cannot be rendered secured to the packaging body only during the setting up of the American box.
La présente invention vise à remédier à cet inconvénient en proposant un emballage du type défini ci-dessus, autre qu'une caisse américaine, dans lequel un unique film de matière plastique rétractable est pincé entre des parties du fond du corps d'emballage à l'état monté, en assurant ainsi après rétraction un excellent maintien en position des objets conditionnés, tout en permettant de livrer l'emballage à plat à l'utilisateur, avec le film de matière plastique collé contre le corps d'emballage, en évitant ainsi l'emploi de matériels coûteux pour sa mise en place, lorsque ce corps d'emballage est mis en volume.The present invention aims to remedy this drawback by proposing a packaging of the type defined above, other than an American box, in which a single film of shrinkable plastic material is pinched between parts of the bottom of the packaging body at the assembled state, thus ensuring, after retraction, excellent retention in position of the packaged objects, while making it possible to deliver the packaging flat to the user, with the plastic film glued against the packaging body, thus avoiding the use of expensive materials for its installation, when this packaging body is placed in volume.
A cet effet, l'invention a pour objet un emballage issu d'un flan unique pour le conditionnement d'au moins un objet, du type comprenant un corps d'emballage en un matériau semi-rigide tel que le carton au le carton ondulé, et un film ininterrompu d'une matière plastique rétractable, qui est solidaire dudit corps et est destiné, après rétraction, à y maintenir ledit objet en position, ledit corps d'emballage comprenant un fond externe rectangulaire ou carré, constitué par un unique panneau attenant par une ligne de pliage à deux premières parois parallèles, le film de matière plastique rétractable s'étendant sur le fond et sur lesdites premières parois parallèlement à deux deuxièmes parois parallèles ou à des volets doublant intérieurement ces deuxièmes parois, cet emballage étant caractérisé en ce que ledit film est contrecollé contre la face interne du fond et verrouillé en position collée par pincement entre le fond et des volets qui doublent intérieurement ce fond et sont attenants par des lignes de pliage aux dites deuxièmes parois ou aux volets doublant intérieurement ces deuxièmes parois.To this end, the subject of the invention is a packaging from a single blank for the packaging of at least one object, of the type comprising a packaging body made of a semi-rigid material such as cardboard or corrugated cardboard. , and an uninterrupted film of a shrinkable plastic, which is integral with said body and is intended, after retraction, to hold said object in position therein, said packaging body comprising a rectangular or square external bottom, constituted by a single panel attached by a fold line to two first parallel walls, the shrinkable plastic film extending on the bottom and on said first walls parallel to two second parallel walls or to flaps internally lining these second walls, this packaging being characterized by that said film is laminated against the internal face of the bottom and locked in the glued position by pinching between the bottom and flaps which internally double this bottom and are adjoined by fold lines to said second walls or to flaps internally lining these second walls .
Dans un tel emballage, le film rétractable est donc maintenu en position, d'une part, par collage contre le fond, d'autre part, par les volets qui doublent intérieurement ce fond et sur lesquels reposent les objets conditionnés. On obtient ainsi un verrouillage en position de ce film et des objets qu'il enserre, ce qui lui permet de ne pas se déplacer en cas de chocs ou de mouvements violents de l'emballage en cours de manutention, même si le ou les objets conditionnés sont d'une masse importante et/ou d'un volume largement inférieur au volume interne de l'emballage.In such packaging, the shrink film is therefore held in position, on the one hand, by gluing against the bottom, on the other hand, by the flaps which internally double this bottom and on which the conditioned objects rest. This obtains a locking in position of this film and of the objects which it encloses, which allows it not to move in the event of impacts or violent movements of the packaging during handling, even if the object or objects packaged are of a large mass and / or a volume much less than the internal volume of the packaging.
Il sera en outre possible de livrer les emballages non montés aux utilisateurs, sous forme d'un unique flan plat de matière semi-rigide pré-découpé et refoulé, avec le film rétractable collé contre le fond, les utilisateurs pouvant ensuite mettre en volume eux-mêmes ces emballages, par des procédés et des appareillages usuels, sans avoir recours à des dispositifs spéciaux et coûteux pour la pose du film plastique.It will also be possible to deliver the unassembled packaging to users, in the form of a single flat blank of semi-rigid material pre-cut and pressed, with the shrink film glued against the bottom, users can then volume them -Even these packaging, by usual methods and equipment, without having to use special and expensive devices for the installation of the plastic film.
Comme on le verra ci-après, dans la description détaillée de certaines formes de mise en oeuvre de l'invention, le corps d'emballage pourra être d'un type connu en soi, ce qui facilitera encore sa mise en volume pour les utilisateurs.As will be seen below, in the detailed description of certain forms of implementation of the invention, the packaging body may be of a type known per se, which will further facilitate its setting in volume for users .
Avantageusement, sur le corps d'emballage livré à plat aux utilisateurs, le film de matière plastique rétractable pourra être rendu temporairement solidaire, par des points de colle, desdites première parois attenantes au fond ou de volets prolongeant ces parois, afin de faciliter la mise en volume du corps d'emballage et son remplissage. Le film est ensuite simplement détaché de ces premières parois ou de ces volets pour être rabattu, à ses deux extrémités, sur les objets conditionnés, avant de procéder à la phase de rétraction.Advantageously, on the packaging body delivered flat to the users, the plastic film retractable may be made temporarily secured, by glue dots, said first walls adjoining the bottom or flaps extending these walls, to facilitate the volume setting of the packaging body and its filling. The film is then simply detached from these first walls or from these flaps to be folded, at its two ends, onto the conditioned objects, before proceeding to the retraction phase.
Comme on le verra dans la description détaillée qui va suivre de diverses formes de mise en oeuvre de l'invention, le film de matière plastique rétractable peut déborder latéralement ou non sur les secondes parois ou sur les volets qui doublent ces parois.As will be seen in the detailed description which follows of various embodiments of the invention, the shrinkable plastic film may extend laterally or not on the second walls or on the flaps which line these walls.

La figure 7 est une vue d'un flan pour la réalisation d'un quatrième emballage conforme à l'invention.Figure 7 is a view of a blank for producing a fourth package according to the invention.
L'emballage représenté sur les figures 1 et 2 comprend un corps d'emballage d'un type connu, de forme générale parallélépipédique, comprenant un fond 1, auquel sont attenantes par des lignes de pliage ou refoulures des parois longitudinales ou première parois 2 et 3.The packaging shown in FIGS. 1 and 2 comprises a packaging body of a known type, of generally parallelepipedal shape, comprising a
Les parois transversales 4 sont attenantes aux extrémités de la paroi longitudinale (secondes parois) 2. A leur base, un volet 5, attenant à ces parois par une ligne de pliage, vient doubler le fond en position montée. A leur partie supérieure, un volet 6, articulé par des lignes de pliage, est rabattu à l'intérieur de l'emballage en position montée pour doubler intérieurement la paroi 4 associée. Une languette 7 de ces volets 6 est engagée dans une découpe 8 du volet 5 correspondant au cours du montage.The
La paroi longitudinale 3 se prolonge latéralement par des volets 9, qui, en position montée, sont engagés entre les parois 4 et les rabats 6.The longitudinal wall 3 is extended laterally by
Un couvercle 10 est articulé par une ligne de pliage à la partie supérieure de la paroi longitudinale 2 et se prolonge par un panneau 11, qui, en position de fermeture, vient s'appliquer contre la face externe de la paroi 3. Ce panneau 11 se prolonge latéralement par des volets 12 ayant une arête 13 incurvée, qui permet de les engager entre les volets 9 et la paroi 4 pendant la phase de fermeture.A
Conformément à l'invention, un film de matière rétractable 14, qui, dans le cas présent, est d'une largeur inferieure à la longueur des parois 2 et 3, est contrecollés contre le fond 1 par des lignes de colle 15, et s'étend parallèlement aux parois transversales 4, sans déborder sur les volets 6 doublant interieurement ces parois.According to the invention, a film of
Il est ainsi possible de livrer à l'utilisateur le flan représente sur la figure 2 avec le film 15 précollé sur le fond, de sorte que l'utilisateur peut procéder lui-même à la mise en volume du conditionnement, de la manière usuelle pour le corps d'emballage, lequel est d'un type bien connu, sans avoir recours à des procédés ou des machines complexes.It is thus possible to deliver to the user the blank shown in FIG. 2 with the
Pour faciliter la mise en volume du corps d'emballage et le conditionnement des objets, le film 14 pourra avantageusement être rendu solidaire de façon temporaire, sur le flan de carton de départ, des premières parois 2 et 3 et éventuellement du couvercle 10, à l'aide de simples points de colle 16. Après montage de l'emballage et mise en place des objets à conditionner, il suffira de détacher le film 14 des parois 2 et 3 et du couvercle 10 pour rabattre ses extrémités sur les objets et procéder à sa rétraction avant de fermer l'emballage.To facilitate the volume of the packaging body and the packaging of the objects, the
Les figures 3 et 4 représentent une autre forme de mise en oeuvre de l'invention, différente de la précédente, mais présentant très exactement les mêmes avantages.Figures 3 and 4 show another form of implementation of the invention, different from the previous one, but having very exactly the same advantages.
Cet emballage comprend également un corps d'emballage d'un type connu de forme générale parallélépipédique, qui comprend un fond 21 attenant à deux parois longitudinales ou premières parois 22 et 23. A la paroi 22 sont attenants latéralement deux volets 24, destinés à former les parois transversales. Celles-ci sont doublées intérieurement par deux volets 25 prolongeant latéralement la paroi longitudlinale 23. A la base de ces volets 25 est raccordé par une ligne de pliage un panneau 26, de dimension inférieure ou non à la moitié de la longueur du fond 21, qui vient doubler intérieurement celui-ci en position montée.This packaging also comprises a packaging body of a known type of generally parallelepiped shape, which comprises a
A la partie supérieure de chacune des parois 22 est articulé par une ligne de pliage un panneau 27, de dimension égale ou supérieure à la moitié de celle du fond 1 et destiné à former un élément de fermeture du corps d'emballage à la partie supérieure de celui-ci.At the upper part of each of the
Les parois externes ou secondes parois 24, d'une part, et les volets 25 qui les doublent intérieurement, d'autre part, sont réunis par des soufflets 20 aux panneaux 27. En position fermée de la caisse, les soufflets 28 sont repliés à plat contre la face interne des volets 25, qu'ils maintiennent ainsi appliqués contre les parois 24. Les parois 24 et les volets 25 peuvent, en outre, être rendus solidaires par collage ou agrafage.The external walls or
Conformément à l'invention, un film de matière plastique 29 est contrecollé contre le fond 21 par des lignes de colle 30 et s'étend parallèlement aux volets 25 doublant intérieurement les parois transversales 24 sans déborder sur ces volets. Il est ainsi possible de livrer aux utilisateurs le flan découpé et refoulé, tel que représenté sur la figure 4, avec le film 29, et le corps d'emballage peut être monté de la façon usuelle, sans dispositifs spéciaux coûteux, en pinçant la partie du film collée sur le fond entre celui-ci et les volets 26, avec une grande sécurité de fixation du film.According to the invention, a
On notera que les volets 26 comportent une découpe 31 dans un angle afin de pouvoir accéder au film 29, après montage, et le dégager si nécessaire.It will be noted that the
Comme dans l'emballage précédemment décrit, des points de colle 32 permettent de solidariser temporairement, sur le flan de départ, le films 29 et les panneaux 27 et/ou les premières parois 22, 23, pour faciliter le montage de l'emballage et la mise en place des objets à conditionner.As in the packaging described above,
Comme précédemment, les extrémités du film 29 sont ensuite dsétachées des panneaux 27 et des parois 22 et 23, rabattues sur les objets, et soumises à une phase de rétraction. Les panneaux 27 peuvent être ensuite rabattus pour fermer l'emballage, et réunis par une bande gommée ou par collage en cas de recouvrement des panneaux.As before, the ends of the
On va décrire maintenant l'emballage des figures 5 et 6, dans lequel le film de matière plastique rétractable est toujours pincé entre le fond et les volets doublant ce fond à l'intérieur, mais qui se distingue des précédents en ce que ledit film déborde latéralement du fond sur les parois qui lui sont parallèles.We will now describe the packaging of Figures 5 and 6, in which the shrinkable plastic film is always pinched between the bottom and the flaps lining the bottom inside, but which differs from the previous ones in that said film overflows laterally from the bottom to the walls which are parallel to it.
Comme dans les réalisations précédentes, le corps de cet emballage comprend un fond externe rectangulaire 41, raccordé à deux parois longitudinales parallèles ou premières parois 42 et 43. A la partie supérieure de la paroi 42 est articulé un couvercle 44, susceptible d'être rabattu parallèlement au fond pour obturer l'emballage, une languette 45, prévue à la partie supérieure de la paroi 43 venant s'engager dans cette position dans une découpe 46 du couvercle.As in the previous embodiments, the body of this packaging comprises a rectangular external bottom 41, connected to two parallel longitudinal walls or
Aux deux extrémités de la paroi 43 sont articulés des volets 47, aptes à être disposés perpendiculairement à cette paroi, pour être pincés entre des panneaux 48, attenants aux extrémités de la paroi 42 et formant la paroi transversale externe ou seconde paroi l'emballage, et des rabats 49, attenants à la partie supérieure de ces parois transversales 48 et rabattus vers le fond.At the two ends of the
A la base des volets 48 sont articulés des volets 50, qui doublent le fond 41 à l'intérieur du corps d'emballage, avec un recouvrement partiel des volets. Des découpes 51, ménagées dans ces volets et éventuellement dans le fond, permettent de verrouiller les rabats 49 en position en y engageant une patte 52 de ces rabats.At the base of the
Des languettes 54, découpées dans une portion du fond et attenantes aux volets 50, sont escamotées par pliage au-dessous de ceux-ci et pincées entre eux et le fond en position montée de l'emballage. Le rôle de ces languettes escamotables sera explicité ci-après.
Un film 55 de matière plastique rétractable est contrecollé contre le fond 41 par des lignes de colle 56. Sur le flan de départ (figure 6), comme dans les emballages décrits précédemment, le film 55 est solidaire temporairement du couvercle et des parois 42 et 43 par des points de colle 57. Le film s'étend parallèlement aux parois transversales 40, mais a une largeur supérieure à la longueur des parois longitudinales 42 et 43, de sorte qu'il déborde latéralement, sur le flan de départ, sur les parois transversales 40. Dans l'emballage monté, ce film est aussi pincé non seulement entre le fond 41 et les volets 50, mais également entre les parois 40 et les volets 47. Comme on le voit sur la figure 5, le long des parois 42 et 43 et sur le couvercle 44, les parties débordantes du film sont toutefois rabattues en 50 sur ces éléments du corps d'emballage. Des découpes sont prévues à cet effet dans les volets 50 doublant le fond, afin de pouvoir accéder au film dans les angles, pour le dégager, les languettes escamotables 54 ont pour but de faciliter le montage de l'emballage et la mise en place du film 55, sur lequel elles glissent au niveau du fond.A
Un tel emballage est destiné au conditionnement d'objets dont le volume est proche du volume interne de l'emballage. Il est, en effet, possible de rabattre les parties repliées 58 du film plastique, sur les faces latérales d'un tel objet, voisines des rabats 49, de façon qu'après la phase de rétraction, l'objet soit ainsi maintenu parfaitement suivant toutes ses faces latérales.Such packaging is intended for packaging objects whose volume is close to the internal volume of packaging. It is, in fact, possible to fold the folded
Cet emballage est cependant d'une conception relativement complexe, aussi la Demanderesse a-t-elle mis au point une quatrième forme de mise en oeuvre de l'invention qui est illustrée par la figure 7.This packaging is however of a relatively complex design, so the Applicant has developed a fourth embodiment of the invention which is illustrated in FIG. 7.
Cette forme de réalisation est relativement proche de celle de la figure 2 et, pour plus de clarté, les organes déjà décrits en référence à cette figure 2 sont désignés par les mêmes chiffres de référence affectés de l'indice. On remarque cependant les différences suivantes par rapport à la figure 2:
- ― le film de matière plastique rétractable 14′ a une largeur supérieure à la longueur des parois longitudinales 2′ et 3′ et il déborde donc latéralement sur les parois latérales;
- ― sur le fond 1′,
le film 14′ présente toutefois un évidement latérale 19′ évitant qu'il ne déborde en dehors du fond et permettant aussi une mise en place aisée des volets 5 doublant le fond; - ― par ailleurs, les volets 6′, correspondant aux volets 49 et la forme de réalisation de la figure 6, ont la même forme que ceux-ci, c'est-à-dire que leurs arêtes, qui sont en position verticale en position montée, sont échancrées en 18′, afin de pouvoir accéder facilement au
film 14′, pour le dégager dans les angles.
- - The
shrinkable plastic film 14 ′ has a width greater than the length of the longitudinal walls 2 ′ and 3 ′ and therefore it extends laterally on the side walls; - - On the bottom 1 ′, the
film 14 ′ however has alateral recess 19 ′ preventing it from overflowing outside the bottom and also allowing easy installation of theflaps 5 doubling the bottom; - - Furthermore, the flaps 6 ', corresponding to the
flaps 49 and the embodiment of Figure 6, have the same shape as these, that is to say that their edges, which are in vertical position mounted, are indented at 18 ′, in order to allow easy access to thefilm 14 ′, to release it in the corners.
Cette forme de réalisation de l'invention, à film débordant latéralement, se prête donc à un montage aussi aisé que la forme de réalisation des figures 1 et 2.This embodiment of the invention, with a film extending laterally, therefore lends itself to assembly as easy as the embodiment of FIGS. 1 and 2.
L'invention apporte donc aux utilisateurs des emballages faciles à monter avec des moyens usuels, qui peuvent leur être livrés avec le film de matière plastique rétractable solidaire du flan dont sera issu le corps d'emballage, et qui présente une grande sécurité de maintien en position du film rétractable et, par conséquent, des objet conditionnés.The invention therefore provides users with packaging that is easy to assemble with conventional means, which can be delivered to them with the shrinkable plastic film integral with the blank from which the packaging body will be derived, and which offers great security of holding the shrink film and, therefore, the packaged objects.
