Description

La présente invention concerne le domaine de l'emballage et plus particulièrement les boîtes à verrouillage constituées d'un fourreau coopérant avec au moins un obturateur.The present invention relates to the field of packaging and more particularly the locking boxes consisting of a sheath cooperating with at least one shutter.

Les systèmes d'emballage destinés à conditionner et à protéger des produits, sont généralement réalisés de façon très simple à partir d'un flan de carton parfois décoré, comportant un fond et un couvercle.The packaging systems intended to condition and protect products, are generally produced in a very simple manner from a sometimes decorated cardboard blank, comprising a bottom and a cover.

Dans certains types de réalisation, le carton utilisé, relativement souple, n'assure pas une bonne résistance tant à la compression, au niveau des parois latérales, qu'à l'écrasement par empilage des produits, ce qui pose des problèmes de détérioration du contenu ou des problèmes de stockage.In certain types of embodiment, the cardboard used, which is relatively flexible, does not provide good resistance both to compression, at the side walls, and to crushing by stacking of the products, which poses problems of deterioration of the content or storage issues.

Etant donné l'obtention de l'emballage à partir d'un flan unique de carton, il est nécessaire de prévoir des extensions latérales pour le couvercle et le fond, ce qui augmente considérablement la surface de carton nécessaire pour obtenir le flan adéquat.Given that the packaging is obtained from a single blank of cardboard, it is necessary to provide lateral extensions for the lid and the bottom, which considerably increases the surface area of cardboard necessary to obtain the adequate blank.

Enfin, la fermeture de la boîte est généralement réalisée par collage voire même uniquement encastrement d'une languette du couvercle, ce qui n'assure pas le verrouillage et donc l'inviolabilité de l'emballage, laquelle inviolabilité est de plus en plus recherchée, spécialement dans les grandes surfaces.Finally, the closure of the box is generally carried out by gluing or even only embedding a tab of the cover, which does not ensure the locking and therefore the inviolability of the packaging, which inviolability is increasingly sought after, especially in large areas.

La présente invention a pour objet une boîte à verrouillage pouvant être utilisée mais non exclusivement, pour le conditionnement de bouteilles, et permettant d'éliminer ces inconvénients.The present invention relates to a locking box which can be used, but not exclusively, for the packaging of bottles, and making it possible to eliminate these drawbacks.

Un premier but de l'invention est de proposer une boîte de conditionnement, verrouillable, présentant un caractère inviolable, l'accès au produit ne pouvant être réalisé que par détérioration de l'emballage.A first object of the invention is to provide a lockable packaging box having an inviolable nature, access to the product can only be achieved by deterioration of the packaging.

Un autre but est de réaliser un conditionnement associant le calage du contenu et une bonne résistance à la compression.Another object is to provide packaging combining the setting of the content and good resistance to compression.

Selon l'invention, la boîte à verrouillage est constituée d'un fourreau en carton et d'au moins un obturateur rapporté comportant, sur ses flancs, des ergots qui coopèrent avec des moyens d'ancrage, disposés à l'une au moins des extrémités dudit fourreau.According to the invention, the locking box consists of a cardboard sheath and at least one reported shutter comprising, on its sides, lugs which cooperate with anchoring means, arranged at at least one of the ends of said sheath.

Toujours selon l'invention, le fourreau est constitué à partir d'un flan unique de carton comprenant, par exemple, quatre parois latérales prolongées, sur au moins un côté formant extrémité, par les moyens d'ancrage en forme de pattes de verrouillage. Lors de la mise en forme de la boîte, ces pattes sont destinées à être rabattues vers l'intérieur pour coopérer avec les ergots de l'obturateur.Still according to the invention, the sheath is formed from a single blank of cardboard comprising, for example, four extended side walls, on at least one side forming an end, by the anchoring means in the form of locking tabs. When the box is shaped, these tabs are intended to be folded inwards to cooperate with the lugs of the shutter.

Selon une disposition particulière, les pattes de verrouillage comportent des encoches qui coopèrent avec les ergots de l'obturateur pour réaliser le verrouillage de l'ensemble.According to a particular arrangement, the locking tabs have notches which cooperate with the lugs of the shutter to achieve the locking of the assembly.

Toujours selon l'invention, l'obturateur destiné à réaliser le fond et/ou le couvercle de la boîte, est constitué d'un noyau dont la forme lui permet de s'inscrire à l'intérieur de l'extrémité du fourreau, et d'une surface plane, formant embase, solidaire du noyau et reposant sur la bordure de l'extrémité du fourreau. L'encombrement de cette surface plane correspond au moins à celui du fourreau.Still according to the invention, the shutter intended to produce the bottom and / or the cover of the box, consists of a core whose shape allows it to fit inside the end of the sheath, and a flat surface, forming a base, integral with the core and resting on the edge of the end of the sheath. The size of this flat surface corresponds at least to that of the sheath.

Selon une autre disposition de l'invention, le noyau de l'obturateur est évidé et la forme de cet évidement est adaptée au contenu de façon à réaliser son calage.According to another arrangement of the invention, the core of the shutter is hollowed out and the shape of this hollow is adapted to the content so as to achieve its setting.

Afin de réaliser un verrouillage correct, les ergots de l'obturateur ont une forme de crochet, d'aspect triangulaire.In order to achieve correct locking, the lugs of the shutter have a hook shape, of triangular appearance.

Par cet ensemble de caractéristiques utilisables isolément ou en combinaison, l'invention permet l'obtention d'un emballage protégeant efficacement les produits contre toute détérioration, grâce aux obturateurs conférant une bonne résistance au conditionnement et assurant un calage correct et précis des produits.By this set of characteristics which can be used individually or in combination, the invention makes it possible to obtain a packaging which effectively protects the products against any deterioration, thanks to the shutters conferring good resistance to packaging and ensuring correct and precise setting of the products.

Ce type de boîte permet également de faire des économies de carton et assure une fermeture définitive ne pouvant être supprimée que par détérioration.This type of box also saves on cardboard and ensures a final closure that can only be removed by deterioration.

Mais l'invention sera encore illustrée, sans être aucunement limitée, par la description suivante de certains modes de rélisation, donnés à titre d'exemples, et représentés sur les dessins annexés, dans lesquels :

  • la figure 1 est une vue en perspective de la boîte selon l'invention munie de deux obturateurs réalisant l'un le fond et l'autre le couvercle,
  • la figure 2 est une vue à plat du flan de carton constituant le fourreau de la boîte,
  • la figure 3 est une vue de dessus de la face interne de l'obturateur,
  • la figure 4 est une vue en coupe de l'obturateur selon 4-4,
  • la figure 5 est une vue partielle et en coupe du positionnement de l'obturateur formant couvercle, sur le fourreau et le produit à conditionner.
However, the invention will be further illustrated, without being in any way limited, by the following description of certain embodiments, given by way of examples, and represented in the appended drawings, in which:
  • FIG. 1 is a perspective view of the box according to the invention provided with two shutters, one providing the bottom and the other the cover,
  • FIG. 2 is a flat view of the cardboard blank constituting the sheath of the box,
  • FIG. 3 is a top view of the internal face of the shutter,
  • FIG. 4 is a sectional view of the shutter according to 4-4,
  • Figure 5 is a partial sectional view of the positioning of the shutter forming a cover, on the sheath and the product to be packaged.

La boîte à verrouillage 1 selon l'invention est représentée figure 1.The locking box 1 according to the invention is shown in Figure 1.

Elle est constituée d'un fourreau de carton 2, de section carrée, associé à deux obturateurs indépendants 3 constituant respectivement le fond et le couvercle de la boîte.It consists of a cardboard sheath 2, of square section, associated with two independent shutters 3 respectively constituting the bottom and the cover of the box.

Le fourreau 2 est réalisé à partir d'un flan unique de carton tel que représenté figure 2. Il comporte quatre parois latérales rectangulaires 21, 22, 23, 24, séparées par des lignes de pliage et prolongées chacune, de chaque côté, par des pattes de verrouillage 25.The sheath 2 is made from a single blank of cardboard as shown in Figure 2. It has four rectangular side walls 21, 22, 23, 24, separated by fold lines and each extended on each side by locking tabs 25.

Chaque patte 25 a une largeur a sensiblement inférieure à la largeur b des parois latérales 21, 22, 23, 24 ; elles sont séparées de leur élément de paroi respectif par des lignes de pliage et elles comportent chacune un orifice 26 de forme générale rectangulaire, disposé environ au niveau de leur partie centrale.Each tab 25 has a width a substantially less than the width b of the side walls 21, 22, 23, 24; they are separated from their respective wall element by fold lines and they each have an orifice 26 of generally rectangular shape, disposed approximately at their central part.

Le côté libre de la paroi latérale 24 est muni d'une extension 27 en forme de languette, destinée à l'association, par collage ou agrafage par exemple, des éléments de paroi 24 et 21, lors de la mise en volume du fourreau 2.The free side of the side wall 24 is provided with an extension 27 in the form of a tongue, intended for the association, for example by gluing or stapling, of the wall elements 24 and 21, when the sheath 2 is being placed in volume. .

Une fois cette solidarisation réalisée, et les parois latérales pliées les unes par rapport aux autres pour obtenir le fourreau de section parallélépipédique, et dans la réalisation représentée, carrée, les pattes de verrouillage 25 sont repliées vers l'intérieur pour obtenir la réalisation de la figure 1. Ce repliage des pattes 25 vers l'intérieur est possible grâce à leur largeur inférieure à celle des parois latérales.Once this is done, and the side walls folded relative to each other to obtain the sheath of rectangular section, and in the embodiment shown, square, the locking tabs 25 are folded inward to obtain the embodiment of Figure 1. This folding of the tabs 25 inward is possible due to their width lower than that of the side walls.

Chaque extrémité du fourreau 2 est alors munie d'un jeu de quatre pattes 25 solidaires chacune d'une paroi 21, 22, 23, 24, formant, à ce niveau, double épaisseur de carton.Each end of the sleeve 2 is then provided with a set of four legs 25 each secured to a wall 21, 22, 23, 24, forming, at this level, double thickness of cardboard.

Etant donné la solidarisation des pattes 25 avec les parois latérales du fourreau, par la seule ligne de pliage d'extrémité, ces pattes 25 ont une certaine élasticité et ont tendance à se dégager légèrement.Given the connection of the legs 25 with the side walls of the sleeve, by the single end fold line, these legs 25 have a certain elasticity and tend to come off slightly.

Les orifices 26 et en particulier leurs arêtes externes 28, sont destinés à servir de moyens d'ancrage pour un organe d'obturation 3, à chaque extrémité du fourreau.The orifices 26 and in particular their external edges 28, are intended to serve as anchoring means for a closure member 3, at each end of the sheath.

Les figures 1, 3, 4 et 5 montrent l'une des réalisations possibles de l'obturateur 3.Figures 1, 3, 4 and 5 show one of the possible embodiments of the shutter 3.

Cet organe d'obturation 3 est identique pour le fond et le couvercle ; il est réalisé de préférence en matériau plastique et consiste en un noyau 31 de forme générale parallélépipédique. Il a des dimensions telles qu'il puisse juste s'inscrire à l'intérieur des extrémités du fourreau 2.This shutter member 3 is identical for the bottom and the cover; it is preferably made of plastic material and consists of a core 31 of generally parallelepiped shape. It has dimensions such that it can just fit inside the ends of the sleeve 2.

Ce noyau 31 est associé à une surface plane 32 formant embase et ayant des dimensions supérieures audit noyau 31 de façon à présenter un rebord périphérique 33.This core 31 is associated with a flat surface 32 forming a base and having dimensions greater than said core 31 so as to present a peripheral rim 33.

L'encombrement de l'embase 32 correspond au moins à celui du fourreau 2 et le rebord 33 est destiné à venir se positionner en appui sur la bordure d'extrémité 4 ou 5 du fourreau.The size of the base 32 corresponds at least to that of the sleeve 2 and the flange 33 is intended to come to rest on the end edge 4 or 5 of the sleeve.

Dans la réalisation représentée figure 1, l'encombrement de la surface plane 32 est sensiblement identique à celui du fourreau 2.In the embodiment shown in FIG. 1, the size of the planar surface 32 is substantially identical to that of the sheath 2.

Le noyau 31 de l'obturateur 3 comporte un ensemble d'ergots 35, disposés latéralement au niveau des flancs 34.The core 31 of the shutter 3 comprises a set of lugs 35, arranged laterally at the sidewalls 34.

Les ergots 35 sont disposés sensiblement au niveau central des flancs 34 et sont destinés à coopérer avec les arêtes externes 28 des orifices 26 des pattes 25, pour réaliser, de chaque côté, le verrouillage de la boîte.The pins 35 are arranged substantially at the level central flanks 34 and are intended to cooperate with the outer edges 28 of the holes 26 of the tabs 25, to achieve, on each side, the locking of the box.

A cet effet, les ergots 35 ont une forme de crochet d'aspect triangulaire en coupe transversale, et ils présentent un côté externe 36 parallèle au rebord périphérique 33 et un côté 37 en pente douce se raccordant aux flancs 34. Ces ergots 35 s'étendent sur un peu plus de la moitié de la longueur des flancs 34.To this end, the lugs 35 have a shape of a hook of triangular appearance in cross section, and they have an external side 36 parallel to the peripheral rim 33 and a side 37 in gentle slope connecting to the sides 34. These lugs 35 s' extend over a little more than half the length of the flanks 34.

Pour assurer le verrouillage de la boîte, le noyau 31 de l'obturateur est inséré dans l'extrémité du fourreau. Les côtés évasés 37 des ergots 35 repoussent les parties supérieures des pattes 25 vers les parois latérales du fourreau, jusqu'à ce que les ergots 35 s'engagent totalement dans les orifices 26.To lock the box, the core 31 of the shutter is inserted into the end of the sleeve. The flared sides 37 of the lugs 35 push the upper parts of the lugs 25 towards the side walls of the sheath, until the lugs 35 fully engage in the orifices 26.

Grâce à leur élasticité, les pattes 25 reviennent vers les flancs 34 de l'obturateur et elles viennent se loger entre le rebord périphérique 33 et le côté 36 des ergots, empêchant tout mouvement de l'organe d'obturation 3.Thanks to their elasticity, the tabs 25 return towards the flanks 34 of the shutter and they are housed between the peripheral rim 33 and the side 36 of the pins, preventing any movement of the shutter member 3.

Le rebord périphérique 33 est limité dans sa course par la bordure d'extrémité 4 ou 5 et l'ergot 35, dans le sens inverse, par les arêtes 28 des pattes 25.The peripheral rim 33 is limited in its travel by the end edge 4 or 5 and the lug 35, in the opposite direction, by the edges 28 of the tabs 25.

A cet effet, la distance séparant le rebord 33 du côté 36 doit être très légèrement supérieure à la distance séparant les bordures d'extrémité 4 ou 5 des arêtes 28.For this purpose, the distance separating the rim 33 from the side 36 must be very slightly greater than the distance separating the end edges 4 or 5 from the edges 28.

On obtient ainsi une boîte verrouillée, inviolable sinon par détérioration.A locked box is thus obtained, inviolable otherwise by deterioration.

L'utilisation d'un matériau plastique rigide, pour réaliser les obturateurs 3, permet d'obtenir une boîte présentant des renforts d'extrémité ; en effet, les noyaux 31, plaqués contre les parois 21, 22, 23, 24, du fourreau 2, renforcent ces parois et évitent en grande partie l'écrasement latéral de la boîte 1.The use of a rigid plastic material, to produce the shutters 3, makes it possible to obtain a box having end reinforcements; in fact, the cores 31, pressed against the walls 21, 22, 23, 24, of the sheath 2, reinforce these walls and largely avoid the lateral crushing of the box 1.

Par ailleurs, la face interne des noyaux 31 peut comporter des évidements ou réservations, destinés d'une part à économiser de la matière plastique et d'autre part à assurer le positionnement et le calage du produit dans l'emballage.Furthermore, the internal face of the cores 31 may include recesses or reservations, intended on the one hand to save plastic material and on the other hand to ensure the positioning and wedging of the product in the packaging.

Dans la réalisation représentée sur les différentes figures, la boîte 1 est destinée à servir de conditionnement à une bouteille 6.In the embodiment shown in the different figures, the box 1 is intended to serve as packaging for a bottle 6.

Pour réaliser un calage et un positionnement corrects de la bouteille 6 dans la boîte, les obturateurs 3, identiques, comportent un évidement 38 dont le fond 39 est muni d'un jeu de trois plots 40.In order to correctly calibrate and position the bottle 6 in the box, the identical shutters 3 have a recess 38, the bottom 39 of which is provided with a set of three studs 40.

L'évidement carré 38, a des côtés correspondant sensiblement au diamètre du culot de la bouteille 6. Les plots 40 de l'obturateur 3 constituant le fond de l'emballage se logent dans la réservation inférieure de la bouteille.The square recess 38 has sides corresponding substantially to the diameter of the base of the bottle 6. The studs 40 of the shutter 3 constituting the bottom of the packaging are housed in the lower reservation of the bottle.

Les trois plots 40 de l'obturateur 3, constituant le couvercle de la boîte, sont destinés à venir se placer autour du bouchon ou du goulot de la bouteille.The three studs 40 of the shutter 3, constituting the cover of the box, are intended to be placed around the stopper or the neck of the bottle.

Les dimensions de la boîte sont telles que les deux fonds 39 des obturateurs 3 viennent juste enserrer le bas et le haut de la bouteille 6 afin d'assurer son calage en longueur et donc la possibilité de superposer différents emballages, sans risque de détérioration par écrasement.The dimensions of the box are such that the two bottoms 39 of the shutters 3 just enclose the bottom and the top of the bottle 6 in order to ensure its wedging in length and therefore the possibility of superimposing different packages, without risk of damage by crushing. .

Bien entendu le fond des obturateurs 3 sera conformé suivant la nature du produit à emballer.Of course the bottom of the shutters 3 will be shaped according to the nature of the product to be packaged.

L'invention ne se limite pas au détail des modes de réalisation, qui n'ont été décrits qu'à titre d'exemples, d'autres variantes pouvant être réalisées, sans sortir du cadre de protection défini par les revendications.The invention is not limited to the detail of the embodiments, which have been described only by way of examples, other variants which can be produced, without departing from the protective framework defined by the claims.

C'est ainsi qu'un seul obturateur peut être utilisé pour réaliser par exemple le couvercle de la boîte, le fond de cette boîte étant réalisé de façon classique, par des extensions au niveau du flan.Thus, a single shutter can be used to produce, for example, the cover of the box, the bottom of this box being produced in a conventional manner, by extensions at the blank.

Le verrouillage des obturateurs 3 sur le fourreau 2 peut être réalisé par seulement trois voire même deux ergots, les parties constitutives de la boîte étant alors aménagées dans ce sens.Locking the shutters 3 on the sheath 2 can be achieved by only three or even two lugs, the constituent parts of the box then being arranged in this direction.

Pour renforcer le caractère d'inviolabilité de la boîte, on peut également prévoir un collage des pattes 25 sur les parois du fourreau.To reinforce the inviolability of the box, it is also possible to provide a bonding of the tabs 25 on the walls of the sheath.

La forme du fourreau 2 et des obturateurs 3 peut également être différente : rectangulaire, polygonale ou autre.The shape of the sheath 2 and the shutters 3 can also be different: rectangular, polygonal or other.

Les signes de référence insérés après les caractéristiques techniques mentionnées dans les revendications ont pour seul but de faciliter la compréhension de ces dernières, et n'en limitent aucunement la portée.The reference signs inserted after the technical characteristics mentioned in the claims are intended only to facilitate the understanding of the latter, and in no way limit their scope.
