Description

La présente invention concerne le domaine technique de l'emballage au sens général et elle vise, plus précisément, un emballage ou un conditionnement d'un objet à l'aide d'une membrane ou d'un film souple, afin d'assurer le maintien de l'objet par suspension ou flottaison.The present invention relates to the technical field of packaging in the general sense and it aims, more specifically, packaging or packaging an object with a membrane or a flexible film, to ensure the keeping the object suspended or floating.

Des emballages de protection sont souvent utilisés quand des objets transportés demande une protection vis-à-vis de chocs, de vibrations ou de chutes. Tel est le cas, par exemple, d'objets fragiles incorporant des composants électroniques.Protective packaging is often used when transported objects require protection against shocks, vibrations or falls. This is the case, for example, of fragile objects incorporating electronic components.

Pour protéger de tels objets, il est connu de faire appel à un emballage du type à suspension. D'une manière classique et tel que cela est décrit, par exemple, par le brevet US 6,302,274 , un tel emballage comporte une caisse, à l'intérieur de laquelle sont disposés deux éléments de calage se présentant chacun sous la forme d'un cadre délimitant une ouverture recouverte d'un film ou d'une membrane souple. L'objet à protéger est pris en sandwich entre les deux films souples des éléments de calage, de sorte que l'objet se trouve en contact avec aucune partie rigide de la caisse. Un tel emballage permet aussi de protéger les produits contre les poussières.To protect such objects, it is known to use a suspension type of packaging. In a conventional manner and as described, for example, by the patent US 6,302,274 such a package comprises a box, inside which are arranged two wedging elements each in the form of a frame defining an opening covered with a film or a flexible membrane. The object to be protected is sandwiched between the two flexible films of the wedging elements, so that the object is in contact with any rigid part of the body. Such packaging also protects products against dust.

Selon une forme connue de réalisation, chaque élément de calage est réalisé par pliage d'un flan de matière prédécoupée, délimitant des volets de côté maintenus en forme par collage.According to a known embodiment, each wedging element is made by folding a blank of pre-cut material, delimiting side shutters held in shape by gluing.

Selon une autre forme de réalisation connue par exemple par le brevet US 6,311,843 , l'élément de calage peut être formé par le pliage, à partir d'un flan de matière prédécoupée, de volets de côté pourvus de volets de liaison et maintenus en position relevée par des moyens de verrouillage du type fentes et languettes. Il a été constaté qu'en cas de chute ou de choc, de tels éléments de calage n'étaient pas adaptés pour assurer une protection pour l'objet maintenu par de tels éléments de calage.According to another embodiment known for example by the patent US 6,311,843 , the wedging element can be formed by folding, from a blank of precut material, side flaps provided with connecting flaps and held in the raised position by means of locking type slots and tabs. It has been found that in the event of a fall or shock, such wedging elements were not adapted to provide protection for the object held by such wedging elements.

L'objet de l'invention vise donc à remédier aux inconvénients de l'art antérieur en proposant un nouvel emballage d'un objet par suspension, conçu pour présenter une réelle protection d'un objet même en cas de choc ou de chute sévère.The object of the invention is therefore to overcome the disadvantages of the prior art by proposing a new packaging of an object by suspension, designed to present a real protection of an object even in case of shock or severe fall.

Pour atteindre un tel objectif, l'élément de calage par suspension d'un objet se présente sous la forme d'un cadre dont le fond délimite une ouverture recouverte d'une membrane souple destinée à être en contact, par friction, avec l'objet, le cadre étant formé par pliage à partir d'un flan de matière prédécoupée comportant au moins trois volets de côté s'étendant selon des lignes de pliage à partir d'une ceinture délimitant l'ouverture et maintenue en position relevée par des moyens de liaison. Selon l'invention, l'élément de calage comporte, pour au moins un volet de côté, un volet de rigidification s'étendant à partir de la ceinture, du côté opposé de celui à partir duquel s'étend ledit volet de côté, le volet de rigidification et le volet de côté associé comportant des moyens de liaison réversible.To achieve such an objective, the suspension element of an object is in the form of a frame whose bottom defines an opening covered with a flexible membrane intended to be in contact, by friction, with the object, the frame being formed by folding from a blank of precut material having at least three side flaps extending along fold lines from a belt defining the opening and held in the raised position by means link. According to the invention, the wedging element comprises, for at least one side flap, a stiffening flap extending from the belt, on the side opposite to that from which said side flap extends, the stiffening flap and the associated side flap having reversible connection means.

Selon une variante préférée de réalisation, chaque volet de rigidification comporte, en tant que moyens de liaison réversible, une patte destinée à s'engager dans une fente aménagée dans le volet de côté associé.According to a preferred embodiment, each stiffening flap comprises, as reversible connection means, a lug intended to engage in a slot in the associated side flap.

Par exemple, l'élément de calage comporte deux volets de rigidification s'étendant en vis-à-vis de deux volets de côté opposés.For example, the wedging element comprises two stiffening flaps extending opposite two opposite side flaps.

Par exemple, l'élément de calage comporte pour chaque volet de côté, un volet de rigidification.For example, the wedging element comprises for each side flap, a stiffening flap.

Pour au moins deux volets de rigidification opposés, les pattes traversent les fentes, de manière à s'étendre en saillie par rapport aux volets de côté placés en position relevée, en vue de constituer une partie de moyens de liaison avec une caisse d'un emballage.For at least two opposite stiffening flaps, the tabs pass through the slots, so as to protrude from the side flaps placed in the raised position, in order to constitute a part of means of connection with a box of a box. packaging.

Selon une variante de réalisation, la membrane souple recouvre l'ouverture, la ceinture et une partie des volets de côté, la membrane étant fixée au cadre par une colle amidon.According to an alternative embodiment, the flexible membrane covers the opening, the belt and a part of the side flaps, the membrane being fixed to the frame by a starch glue.

Avantageusement, la membrane souple est fixée au cadre avec une pré-tension correspondant à un allongement compris entre 10 et 35 % et, de préférence, de l'ordre de 30 %.Advantageously, the flexible membrane is fixed to the frame with a pre-tension corresponding to an elongation of between 10 and 35% and, preferably, of the order of 30%.

Selon un exemple de réalisation, au moins certains des volets de côté sont pourvus de volets de liaison destinés à être maintenus en position relevée contre des volets de côté adjacents par des moyens de liaison du type à verrouillage réversible.According to an exemplary embodiment, at least some of the side flaps are provided with connecting flaps intended to be held in raised position against adjacent side flaps by reversible locking type connecting means.

Selon cette variante, les moyens de verrouillage réversible comprennent des pattes destinées à s'engager chacune dans des fentes aménagées dans les volets de côté.According to this variant, the reversible locking means comprise tabs intended to engage each in slots arranged in the side shutters.

Par exemple, chaque patte est aménagée dans un volet de liaison prolongeant un volet de côté et destinée à s'engager dans une fente aménagée sur un volet de côté adjacent.For example, each leg is arranged in a connecting flap extending a side flap and intended to engage in a slot on an adjacent side flap.

De préférence, la fente possède un profil courbe pour faciliter l'engagement de la patte.Preferably, the slot has a curved profile to facilitate engagement of the tab.

D'une manière classique, le cadre présente une section de forme générale en quadrilatère avec quatre volets de côté.In a conventional manner, the frame has a section of generally quadrilateral shape with four side shutters.

Selon un exemple préféré de réalisation, le volet de liaison est relié au volet de côté par l'intermédiaire d'un volet de renfort d'angle qui s'étend dans un coin du cadre, entre deux volets de côté adjacents, en position relevée des volets.According to a preferred embodiment, the connecting flap is connected to the side flap by means of a corner reinforcing flap which extends in a corner of the frame, between two adjacent side flaps, in the raised position. Shutters.

Par exemple, les volets de côté sont pourvus de contre-volets s'étendant chacun selon une ligne de pliage parallèle à la ligne de pliage du volet de côté associé, les contre-volets étant pourvus de pattes ou d'encoches qui coopèrent, respectivement, avec les encoches et les pattes, en vue d'assurer le verrouillage en position relevée du contre-volet et du volet de côté, lorsque ces derniers sont rabattus l'un sur l'autre.For example, the side flaps are provided with back flaps, each extending along a fold line parallel to the fold line of the associated side flap, the counterflaps being provided with cooperating tabs or notches, respectively , with the notches and tabs, for locking in the raised position of the counter-flap and the side flap, when the latter are folded over one another.

De préférence, chaque volet de liaison est interposé entre un volet de côté et un contre-volet adjacent.Preferably, each connecting flap is interposed between a side flap and an adjacent flap.

Selon une autre variante de réalisation, les volets de côté sont assemblés entre eux à l'aide de moyens de liaison et de volets de liaison, les volets de côté opposés étant pourvus de lignes de pliage pour permettre le pliage des volets de côté adjacents de manière à assurer le pliage à plat de l'élément de calage.According to another embodiment, the side flaps are assembled together by means of connecting means and connecting flaps, the opposite side flaps being provided with fold lines to allow the folding of the adjacent side flaps of in order to ensure the flat folding of the wedging element.

Un autre objet de l'invention vise à protéger un emballage d'un objet par suspension comportant au moins deux éléments de calage conforme à l'invention, montés à l'intérieur d'une caisse en étant disposés sur les côtés opposés de l'objet.Another object of the invention is to protect a package of an object by suspension comprising at least two wedging elements according to the invention, mounted inside a body being arranged on the opposite sides of the body. object.

Conformément à l'invention, la caisse comporte des fentes dans chacune desquelles s'engage une patte s'étendant en saillie à partir des éléments de calage, de manière à assurer une liaison entre chaque élément de calage et la caisse.According to the invention, the box has slots in each of which engages a tab projecting from the elements of wedging, so as to ensure a connection between each wedging element and the body.

Les fig. 8 et 9 sont des vues d'un autre exemple de réalisation d'un élément de calage conforme à l'invention illustré respectivement à plat et en position formée.The Fig. 8 and 9 are views of another embodiment of a wedging element according to the invention shown respectively flat and in the formed position.

Les fig. 1 et 2 illustrent un emballage ou un conditionnement 1 conforme à l'invention, adapté pour protéger un objet 2 au sens général par une technique, dite de suspension ou de flottaison. L'emballage 1 présente une forme et une dimension adaptées à la taille de l'objet 2 qui peut être de toute nature, par exemple à caractère électronique. Dans l'exemple illustré, l'objet 2 est une imprimante.The Fig. 1 and 2 illustrate a packaging or packaging 1 according to the invention, adapted to protect an object 2 in the general sense by a technique, called suspension or flotation. The package 1 has a shape and a dimension adapted to the size of the object 2 which can be of any kind, for example electronic character. In the example illustrated, the object 2 is a printer.

L'emballage 1 comporte une boîte ou une caisse 3, à caractère rigide, telle qu'une caisse américaine réalisée en carton. La caisse 3 délimite un volume interne 4, accessible par un passage 6 destiné à être fermé par un couvercle 7. The package 1 comprises a box or a box 3, of a rigid nature, such as an American box made of cardboard. The box 3 delimits an internal volume 4, accessible via a passage 6 intended to be closed by a lid 7.

Dans l'exemple illustré, la caisse 3 présente une forme parallélépipédique en comportant un fond 9, à partir duquel s'élèvent quatre parois latérales 10, munies chacune d'un rabat 11 pour former le couvercle 7 venant fermer le passage 6. Dans l'exemple illustré, le passage 6 présente une forme de quadrilatère. Bien entendu, il pourrait être envisagé de conférer à la caisse une forme différente.In the example shown, the box 3 has a parallelepipedal shape with a bottom 9, from which rise four side walls 10, each provided with a flap 11 to form the lid 7 which closes the passage 6. In illustrated example, the passage 6 has a quadrilateral shape. Of course, it could be envisaged to give the fund a different form.

L'emballage 1 selon l'invention comporte, également, au moins deux éléments de calage 14 destiné à être montés à l'intérieur de la caisse 3 en étant disposés de part et d'autre de l'objet 2, c'est-à-dire sur les côtés opposés de l'objet 2, tel que cela ressort clairement des fig. 1 et 2 . Chaque élément de calage 14 se présente, tel que cela ressort plus précisément de la fig. 3 , sous la forme d'un cadre 15 dont le fond délimite une ouverture 16 recouverte d'une membrane ou d'un film souple 17 destiné à être en contact, par friction, avec l'objet 2. Cet élément de calage 14 présente une forme ou un contour adapté, au jeu près, à la section de passage de la caisse 3, de manière à être introduit, à l'intérieur de la caisse, avec l'ouverture 16 s'établissant dans un plan sensiblement perpendiculaire aux parois latérales 10 de la caisse.The packaging 1 according to the invention also comprises at least two wedging elements 14 intended to be mounted inside the box 3 while being arranged on either side of the object 2, that is, on opposite sides of the object 2, as is clear from the Fig. 1 and 2 . Each wedging element 14 is presented, as is more specifically apparent from the Fig. 3 , in the form of a frame 15 whose bottom defines an opening 16 covered with a membrane or a flexible film 17 intended to be in contact, by friction, with the object 2. This wedging element 14 has a shape or contour adapted, with the game, to the passage section of the body 3, so as to be introduced into the body, with the opening 16 being established in a plane substantially perpendicular to the side walls 10 of the box.

Conformément à l'invention, l'élément de calage 14 est formé par pliage à partir d'un flan de matière prédécoupée, telle que du carton. Comme illustré à la fig. 4 , le flan de matière prédécoupée comporte au moins trois et, dans l'exemple illustré, quatre volets de côté 20 rattachés chacun, par une ligne de pliage l, à une ceinture 21 formant le fond et délimitant l'ouverture 16 par son bord interne. La ceinture 21 délimite, par son bord externe correspondant aux lignes de pliage l, la section de passage de l'élément de calage correspondant, au jeu près, à la section du passage 6 de la caisse.According to the invention, the wedging element 14 is formed by folding from a blank of precut material, such as cardboard. As illustrated in Fig. 4 , The pre-cut blank of material comprises at least three and, in the example shown, four side flaps 20 each attached by a fold line L, to a bottom 21 forming the belt and defining the opening 16 by its inner edge . The belt 21 delimits, by its outer edge corresponding to the fold lines 1, the passage section of the wedging element corresponding, with the game, to the section of the passage 6 of the body.

Dans l'exemple illustré sur les dessins, le cadre 15, délimité par la ceinture 21, présente une section en forme de quadrilatère. La ceinture 21 est ainsi pourvue, sur chacun de ses quatre côtés décalés deux à deux de 90°, d'un volet 20 apte à être rabattu ou relevé autour de sa ligne de pliage l, selon une direction sensiblement perpendiculaire au plan d'extension de la ceinture 21 ( fig. 5 ). Les volets de côté 20 sont maintenus dans cette position relevée par des moyens 25 de verrouillage ou de liaison réversible.In the example illustrated in the drawings, the frame 15, delimited by the belt 21, has a quadrilateral-shaped section. The belt 21 is thus provided, on each of its four sides offset two by two by 90 °, a flap 20 adapted to be folded or raised around its fold line 1 , in a direction substantially perpendicular to the extension plane of the belt 21 ( Fig. 5 ). The side flaps 20 are held in this raised position by means 25 for locking or reversible binding.

Dans l'exemple illustré aux fig. 4 à 7 , ces moyens de verrouillage 25 comportent, avantageusement, des paires de pattes 26 et de fentes 27 aménagées dans les volets de côté 20. Dans l'exemple de réalisation illustré aux fig. 4 et 5 , une patte 26, portée par un volet de côté 20, est destinée à s'engager dans une fente 27 aménagée sur un volet de côté adjacent. Selon une caractéristique préférée de réalisation illustrée plus précisément à la fig. 4 , deux volets 20 opposés sont pourvus, sur chacun de ses bords latéraux, d'une fente 27, tandis que les deux autres volets de côté opposés 20 sont pourvus, sur leurs côtés latéraux, d'une patte 26. Selon une caractéristique de réalisation, chaque patte 26 est réalisée dans un volet de liaison 28 raccordé au volet de côté par une ligne de pliage l1 s'étendant selon une direction perpendiculaire à la direction de la ligne de pliage l dudit volet. Tel que cela ressort de la fig. 5 , chaque volet de liaison 28 est replié pour s'étendre parallèlement au volet 20 voisin placé en position relevée. Chaque volet de liaison 28 s'étend à l'intérieur du volet 20, sur une partie de sa longueur, avec sa patte 26 qui, passant à travers la fente 27, s'étend à l'extérieur du volet 20. In the example shown in Fig. 4 to 7 These locking means 25 comprise, advantageously, pairs of tabs 26 and slots 27 arranged in the side flaps 20. In the embodiment illustrated in Fig. 4 and 5 A lug 26 carried by a side flap 20 is adapted to engage in a slot 27 arranged on an adjacent side flap. According to a preferred embodiment characteristic illustrated more precisely in the Fig. 4 Two opposing flaps 20 are provided on each of its side edges, a slot 27, while the other two parts of opposite side 20 are provided on their lateral sides, with a lug 26. According to an embodiment characteristic each tab 26 is made of a connection flap 28 connected to the side flap by a fold line l 1 extending in a direction perpendicular to the direction of the fold line of said flap. As is apparent from the Fig. 5 Each connection flap 28 is folded to extend parallel to the adjacent flap 20 placed in the raised position. Each connecting flap 28 extends inside the flap 20, over part of its length, with its tab 26 which, passing through the slot 27, extends outside the flap 20.

Selon une caractéristique préférée de réalisation, chaque volet de liaison 28 est relié au volet de côté 20 voisin, par l'intermédiaire d'un volet de renfort d'angle 30 qui est relié au volet de côté par une ligne de pliage l 2 parallèle à la ligne de pliage l1 voisine. Tel que cela ressort plus précisément de la fig. 5 , le volet de renfort d'angle 30 s'étend dans un coin du cadre 15, entre deux volets de côté 20 adjacents s'étendant en position relevée. Dans cette position relevée, chaque volet de liaison 28 recouvre une partie du côté adjacent voisin 20, avec sa patte 26 engagée dans une fente 27. Le volet de renfort 30 s'étend ainsi entre deux volets adjacents 20 selon un angle de l'ordre de 45°. Selon une caractéristique préférée de réalisation, chaque fente 27 possède un profil courbe pour faciliter l'engagement de la patte. Chaque fente 27 s'étend ainsi sur un quart de cercle.According to a preferred characteristic, each connection flap 28 is connected at 20 adjacent side flap via an angle reinforcing flap 30 which is connected to the side flap by a fold line parallel l 2 at the folding line l 1 neighbor. As is more particularly apparent from the Fig. 5 , the corner reinforcing flap 30 extends in a corner of the frame 15, between two adjacent side flaps 20 extending in the raised position. In this raised position, each connecting flap 28 covers a portion of the adjacent adjacent side 20, with its lug 26 engaged in a slot 27. The reinforcing flap 30 thus extends between two adjacent flaps 20 at an angle of the order 45 °. According to a preferred embodiment, each slot 27 has a curved profile to facilitate the engagement of the tab. Each slot 27 thus extends over a quarter circle.

Selon une autre caractéristique de l'invention, la ceinture 21 du cadre comporte, à chaque coin et à partir de son bord interne, une languette 33 de renfort destinée à se replier sur la ceinture 21 à la base d'un volet de renfort d'angle 30. Cette languette 33 est ainsi interposée entre la ceinture 21 et la base du volet de renfort 30. According to another characteristic of the invention, the belt 21 of the frame comprises, at each corner and from its inner edge, a tongue 33 of reinforcement intended to fold over the belt 21 at the base of a corner reinforcement flap 30. This tongue 33 is thus interposed between the belt 21 and the base of the reinforcement flap 30.

Selon une caractéristique de l'invention, la ceinture 21 comporte, pour au moins un et dans l'exemple les quatre volets de côté 20 opposés, des volets de rigidification ou de renfort 40 s'étendant à partir du bord interne de la ceinture 21. Chaque volet de rigidification 40 s'étend en vis-à-vis d'un volet de côté 20 voisin, selon une ligne de pliage l3 qui est sensiblement parallèle à la ligne de pliage l voisine. Tel que cela ressort des fig. 4 et 5 , un volet de rigidification 40 s'étend ainsi à partir de la ceinture 21 du côté opposé de celui à partir duquel s'étend le volet de côté 20. Le volet de rigidification 40 et le volet de côté associé 20 comportent des moyens de liaison ou de verrouillage 42 réversible, permettant une liaison, après pliage du volet de rigidification 40, entre le volet de rigidification 40 et le volet de côté 20 occupant sa position relevée. Chaque volet de rigidification 40 comporte, en tant que moyens de verrouillage réversible 42, une patte 43 tournée en direction opposée de la ligne de pliage l3 et destinée à s'engager dans une fente 45 aménagée dans le volet de côté 20 associé.According to a characteristic of the invention, the belt 21 comprises, for at least one and in the example the four opposite side flaps 20 , reinforcing or reinforcing flaps 40 extending from the inner edge of the belt 21 . Each reinforcing flap 40 extends vis-à-vis an adjacent side flap 20, along a folding line l 3 which is substantially parallel to the fold line the neighbor. As is apparent from Fig. 4 and 5 , a stiffening flap 40 thus extends from the belt 21 on the opposite side from that from which the side flap 20 extends. The stiffening flap 40 and the associated side flap 20 comprise reversible connection or locking means 42 , allowing a connection, after folding of the stiffening flap 40, between the stiffening flap 40 and the side flap 20 occupying its position. identified. Each stiffening flap 40 comprises, as reversible locking means 42, a tab 43 turned in the opposite direction of the folding line 13 and intended to engage in a slot 45 formed in the associated side flap 20 .

Dans l'exemple de réalisation illustré sur les fig. 4 et 5 , deux volets de rigidification 40 sont situés en vis-à-vis des deux volets de côté 20 ne comportant pas les fentes 27. Ces deux volets de rigidification 40 s'étendent en position de coopération avec les volets de côté 20, sur la majeure partie de la hauteur de ces volets de côté 20. La ceinture 21 comporte également pour les volets de côté 20 pourvus des fentes 27, des volets de rigidification ou de renfort 46 s'étendant chacun à partir d'une ligne de pliage l 3 parallèle à la ligne de pliage I voisine. Ces deux volets de renfort 46 et les volets de côté 20 associés comportent des moyens de liaison ou de verrouillage réversible 47 permettant une rigidification du volet de côté 20. Ces moyens de verrouillage réversible 47 comprennent une patte 48, aménagée sur chaque volet de renfort 46, en direction opposée de la ligne de pliage l3 et destinée à s'engager, en position relevée du volet de côté, dans une fente 49 aménagée dans le volet de côté 20 en vis-à-vis. Tel que cela ressort des figures, les volets de renfort 46 jouent le rôle d'étai pour les volets de côté 20. In the exemplary embodiment illustrated on the Fig. 4 and 5 , two stiffening flaps 40 are located opposite the two side flaps 20 not having the slots 27. These two stiffening flaps 40 extend in the position of cooperation with the side flaps 20, on the major part of the height of these side flaps 20. the belt 21 also has to the side flaps 20 provided with the slots 27, shutters stiffening or reinforcement 46 each extending from a fold line parallel l 3 at the fold line I next. These two reinforcing flaps 46 and the associated side flaps 20 comprise reversible locking or locking means 47 for stiffening the side flap 20. These reversible locking means 47 comprise a tab 48, provided on each reinforcement flap 46 in opposite direction of the bending line l 3 and designed to engage, in the raised position of the side flap, in a slot 49 arranged in the side flap 20 in vis-à-vis. As can be seen from the figures, the reinforcement flaps 46 act as struts for the side flaps 20.

Selon une caractéristique préférée de réalisation, pour au moins deux volets de rigidification opposés 40 correspondant, dans l'exemple illustré, aux volets situés en relation des volets de côté 40 ne comportant pas les fentes 27, les pattes 43 traversent les fentes 45, de manière à s'étendre en saillie par rapport aux volets de côté 20, placés en position relevée, en vue de constituer une partie de moyens de liaison 50 avec la caisse 3 de l'emballage.According to a preferred embodiment, for at least two opposite stiffening flaps 40 corresponding, in the illustrated example, flaps located in relation to side flaps 40 not having the slots 27, the tabs 43 pass through the slots 45, so as to protrude from the side flaps 20, placed in the raised position, to form a part of connection means 50 with the box 3 of the package.

Ainsi que cela ressort plus précisément de la fig. 2 , chaque patte 43 est destinée à venir s'engager dans une fente 51 réalisée dans la caisse 3, de manière à assurer une liaison entre chaque élément de calage 14 et la caisse 3. Les moyens de liaison 50 permettent de maintenir en position fixe les deux éléments de calage 14 à l'intérieur de la caisse 3. As is clear from the Fig. 2 Each tab 43 is intended to engage in a slot 51 formed in the body 3, so as to ensure a connection between each clamping element 14 and the body 3. The connecting means 50 allow to maintain in fixed position two wedging elements 14 inside the body 3.

La mise en oeuvre de l'objet de l'invention découle directement de la description qui précède.The implementation of the subject of the invention follows directly from the foregoing description.

A partir du flan de matière prédécoupée, l'élément de calage 14 est conformé par le pliage des volets de côté 20 et leur maintien à l'aide des moyens de verrouillage réversible 25 consistant à l'engagement des pattes 26 à l'intérieur des fentes 27. Les languettes 33 sont rabattues contre les volets de renfort d'angle 30, tandis que les volets de rigidification 40 et de renfort 46 sont fixés aux volets de côté en vis-à-vis à l'aide des moyens de verrouillage réversible, respectivement 42 et 47. Un tel élément de calage 14 présente une bonne rigidité, en étant conformé à l'aide de moyens de verrouillage réversible. Ainsi, après utilisation, l'élément de calage 14 peut retrouver une conformation sensiblement plane après suppression des moyens de liaison réversible 25, 42, 47. A cet effet, les pattes 26, 43, 48 sont dégagées des fentes 27, 45, 49. From the blank of pre-cut material, the wedging element 14 is shaped by the folding of the side flaps 20 and their retention by means of the reversible locking means 25 consisting of the engagement of the tabs 26 inside the slits 27. The tongues 33 are folded against the corner reinforcing flaps 30, while the stiffening flaps 40 and reinforcement 46 are fixed to the side flaps facing each other by means of the reversible locking means , respectively 42 and 47. Such a wedging element 14 has a good rigidity, being shaped by means of reversible locking means. Thus, after use, the wedging element 14 can return to a substantially flat conformation after removal of the reversible connection means 25, 42, 47. For this purpose, the tabs 26, 43, 48 are disengaged from the slots 27, 45, 49 .

Un tel élément de calage 14 est destiné à assurer le conditionnement d'un objet 2 en étant introduit à l'intérieur de la caisse 3 avec la membrane souple 17 tournée vers la partie supérieure de la caisse 3. L'élément de calage 14 est glissé à l'intérieur de la caisse 3 jusqu'au moment où les pattes 43 coopèrent avec les fentes 51 de la caisse 3. L'élément de calage 14, dit inférieur, se trouve ainsi positionné de manière fixe à l'intérieur de la caisse 3. L'objet 2 est ensuite introduit à l'intérieur de la caisse pour être supporté par la membrane souple 17. Such a wedging element 14 is intended to ensure the conditioning of an object 2 by being introduced inside the body 3 with the flexible membrane 17 turned towards the upper part of the body 3. The wedging element 14 is slid inside the box 3 until the tabs 43 cooperate with the slots 51 of the box 3. The wedging element 14, said lower, is thus positioned in a fixed manner inside the box 3. The object 2 is then introduced inside the box to be supported by the flexible membrane 17.

Un autre élément de calage 14, dit supérieur, est ensuite introduit à l'intérieur de la caisse avec la membrane souple 17 tournée vers l'objet 2. En d'autres termes, les éléments de calage 14 se trouvent montés tête bêche à l'intérieur de la caisse 3. L'élément de calage 14, dit supérieur, est déplacé à l'intérieur de la caisse jusqu'à l'engagement des pattes 43 à l'intérieur des fentes 51. Dans cette position, l'élément de calage 14, dit supérieur, se trouve bloqué en position fixe à l'intérieur de la caisse. Les moyens de liaison 50 permettent d'assurer un positionnement correct des éléments de calage 14 à l'intérieur de la caisse 3 et, par suite, un maintien efficace de l'objet par les membranes souples 17. Another wedging element 14, said upper, is then introduced inside the body with the flexible membrane 17 facing the object 2. In other words, the wedging elements 14 are mounted head to tail to the 3. The wedging element 14, said upper, is moved inside the body until the tabs 43 engage the slots 51. In this position, the element wedge 14, said higher, is locked in a fixed position inside the body. The connecting means 50 make it possible to ensure a correct positioning of the wedging elements 14 inside the body 3 and, consequently, an effective retention of the object by the flexible membranes 17.

Selon une autre caractéristique avantageuse de réalisation, la membrane souple 17 recouvre l'ouverture 16, la ceinture 21 et une partie des volets de côté 20. La membrane souple est fixée au cadre, avantageusement par une colle amidon. D'une manière avantageuse, la membrane souple 17 est fixée sur l'élément de calage 14, de manière pré-tendue. Ainsi, la membrane 17 est fixée sur l'élément de calage 14 avec une pré-tension correspondant à un allongement compris entre 10 et 35 % et, de préférence, de l'ordre de 30 % par rapport à sa position de repos.According to another advantageous characteristic of embodiment, the flexible membrane 17 covers the opening 16 , the belt 21 and a part of the side flaps 20. The flexible membrane is fixed to the frame, preferably by a starch adhesive. Advantageously, the flexible membrane 17 is fixed on the wedging element 14, pre-stretched. Thus, the membrane 17 is fixed on the wedging element 14 with a pretension corresponding to an elongation of between 10 and 35% and, preferably, of the order of 30% relative to its rest position.

Les fig. 6 et 7 illustrent une autre variante de réalisation d'un élément de calage 14 conforme à l'invention, réalisé à partir d'un flan et dont les volets de côté 20 sont maintenus en position relevée par des moyens de verrouillage réversible 25. Selon cette variante de réalisation, l'élément de calage 14 comporte quatre volets de côté 20 s'étendant, à partir de la ceinture 21, à partir des lignes de pliage l, tel que décrit précédemment. Selon cette variante de réalisation, chaque volet de côté 20 est pourvu d'un contre-volet 60 s'étendant selon une ligne de pliage l 4 parallèle à la ligne de pliage I du volet de côté 20 associé. Au moins deux volets de côté 20 opposés et les contre-volets 60 associés sont munis, en tant que moyens de verrouillage réversible 25, de pattes 61 coopérant avec des encoches 62. Dans l'exemple illustré, chaque contre-volet 60 est muni de deux pattes 61, destinées à coopérer chacune, après rabattement du contre-volet 60 sur son volet associé 20, avec une encoche 62 aménagée dans la ceinture 21 en bordant la ligne de pliage l.The Fig. 6 and 7 illustrate another alternative embodiment of a wedging element 14 according to the invention, made from a blank and whose side flaps 20 are held in the raised position by reversible locking means 25. According to this variant of FIG. In that embodiment, the wedging element 14 has four side flaps 20 extending from the belt 21 from the fold lines 1 as previously described. According to this alternative embodiment, each side flap 20 is provided with a against-flap 60 extending along a fold line l 4 parallel to the fold line I to 20 associated side pane. At least two opposite side flaps 20 and the associated back-flaps 60 are provided as reversible locking means 25 with lugs 61 cooperating with notches 62. In the illustrated example, each counter-flap 60 is provided with two tabs 61, intended to cooperate each, after folding of the counter-flap 60 on its associated flap 20, with a notch 62 formed in the belt 21 bordering the fold line 1 .

Avantageusement, avant le rabattement du contre-volet 60 sur son volet de côté 20 associé, les volets de liaison 28 sont interposés entre le contre-volet 60 et leur volet de côté 20. Chaque volet de liaison 28 présente une longueur légèrement inférieure à la demi-longueur du contre-volet, de sorte que le cadre comporte trois épaisseurs de flan de matière sur deux de ses côtés, permettant d'augmenter la rigidité de l'élément de calage 14. Bien entendu, la position des pattes 61 et des encoches 62 pourrait être inversée.Advantageously, before folding the counter-flap 60 on its associated side flap 20 , the connecting flaps 28 are interposed between the flap 60 and their side flap 20. Each connecting flap 28 has a length slightly less than the half-length of the counter-flap, so that the frame has three thicknesses of material blank on two of its sides, to increase the rigidity of the wedging element 14. Of course, the position of the legs 61 and notches 62 could be reversed.

Les deux autres volets de côté 20, qui comportent les volets de liaison 28, sont maintenus aussi en position relevée à l'aide des volets de rigidification 40 dont chaque patte 43 coopère avec les fentes 45 aménagées dans le volet de côté 20 et le contre-volet associé 60. Il peut donc être estimé que le cadre comporte, sur chacun de ses quatre côtés, trois épaisseurs de flan de matière. Selon cette variante, l'élément de calage ne comporte pas les volets de renfort 48. Cependant, selon cette dernière variante de réalisation, l'élément de calage 14 comporte les languettes de renfort 33 coopérant avec la base d'un volet de renfort d'angle 30. The other two side flaps 20, which comprise the connecting flaps 28, are also maintained in the raised position by means of the stiffening flaps 40 , each lug 43 cooperating with the slots 45 formed in the side flap 20 and the against Associated wheel 60. It can therefore be estimated that the frame comprises, on each of its four sides, three thicknesses of blank of material. According to this variant, the wedging element does not comprise the reinforcement flaps 48. However, according to this last variant embodiment, the wedging element 14 comprises the reinforcement tongues 33 cooperating with the base of a reinforcement flap. angle 30.

Les fig. 8 et 9 illustrent un autre exemple de réalisation d'un élément de calage 14 dont les volets de côté 20 sont assemblés entre eux à l'aide de moyens de liaison non réversible. Selon cet exemple de réalisation, l'élément de calage 14 dont on ne décrira pas les éléments communs avec les variantes déjà décrites, comporte quatre volets de côté 20 rattachés à la ceinture 21 et pourvus dans leur prolongement, de volets de liaison 28 qui sont assemblés aux volets de côté 20 voisins par des moyens de liaison tels que de la colle. Deux volets de côté 20 situés à l'opposé l'un de l'autre comportent des lignes de pliage l4 pour permettre le pliage des volets de côté 20 adjacents pour assurer un pliage à plat de l'élément de calage 14. Tel que cela ressort des figures, une ligne de pliage I4 s'étend en biais à partir des deux coins de chacun desdits volets de côté 20 opposés, jusqu'au bord libre dudit volet de côté 20 sur une hauteur égale à celle du volet de côté 20 adjacent.The Fig. 8 and 9 illustrate another embodiment of a wedging element 14 , the side flaps 20 are assembled together by means of non-reversible connection means. According to this exemplary embodiment, the wedging element 14 whose elements common to the variants already described will not be described, comprises four side flaps 20 attached to the belt 21 and provided in their extension with connecting flaps 28 which are joined to the flaps 20 adjacent side by connection means such as glue. Two mutually opposite side flaps 20 have fold lines 14 to allow folding of the adjacent side flaps 20 to provide a flat folding of the wedging member 14. As shown in FIG . this is apparent from the figures, a fold line I 4 extends obliquely from the two corners of each of said opposite side flaps 20 to the free edge of said side flap 20 to a height equal to that of the side flap 20 adjacent.

Le déploiement de l'élément de calage 14 consiste à plier les volets de côté 20 selon leur ligne de pliage I de sorte que les volets de côté 20 s'étendent de manière relevée par rapport à la ceinture 21. Même si les volets de côté 20 sont assemblés ensemble de manière non temporaire ou de façon irréversible, la présence des lignes de pliage l4 permet à l'élément de calage 14 d'occuper une position déployée dans laquelle les volets de côté 20 sont relevés et une position repliée ou à plat où les volets de côté 20 sont rabattus ou pliés contre la ceinture 21. The deployment of the wedging element 14 consists in folding the side flaps 20 along their folding line I so that the side flaps 20 extend in a raised manner with respect to the belt 21. Even if the side flaps 20 are assembled together in a non-temporary or irreversibly manner, the presence of the folding lines 14 allows the wedging element 14 to occupy an extended position in which the side flaps 20 are raised and a folded or flat position where the side flaps 20 are folded or folded against the belt 21.

Les volets de côté 20 sont maintenus en position relevée par l'intermédiaire de deux volets de rigidification 40 qui s'étendent en vis-à-vis de deux volets de côté 20 opposés. Ces volets de rigidification qui comportent une patte 43 destinée à s'engager dans une fente 45 aménagée dans le volet de côté 20 associé, assurent aussi un verrouillage de l'élément de calage 14. Il est à noter que ces pattes 43 et fentes 45 constituent des moyens de verrouillage réversible 42 puisque le désengagement des pattes 43 par rapport aux fentes 45 permet de remettre l'élément de calage 14 à plat.The side flaps 20 are held in the raised position by means of two stiffening flaps 40 which extend opposite two opposite side flaps 20 . These stiffening flaps which comprise a tab 43 intended to engage in a slot 45 formed in the associated side flap 20 , also provide a locking of the wedging element 14. It should be noted that these lugs 43 and slots 45 constitute reversible locking means 42 since the disengagement of the tabs 43 relative to the slots 45 makes it possible to return the wedging element 14 flat.

L'invention n'est pas limitée aux exemples décrits et représentés car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the examples described and shown because various modifications can be made without departing from its scope.
