Abstract

The subject of the invention is a pallet box made of a semi-rigid material, of the type which the bottom comprises two external flaps (7) respectively adjoining two parallel walls (8) by a folding line, each flap carrying on its external face at least three parallel sleeves (11, 17), perpendicular to the said parallel walls and respectively disposed in alignment with the sleeves associated with the other flap, a strengthening block of complementary profile (12, 16) and made of a rigid material being engaged in the sleeves disposed facing each other. According to the invention, in at least one of the said flaps (7) there is cut out an element (14) forming an emptying hatch, mounted such that it pivots about a folding line (15) with respect to the said flap, the said element (14) forming a hatch being disposed such that it is held in position in the plane of the associated flap by one (16) of the said strengthening blocks and that it can pivot freely when this block is withdrawn, whilst the other two blocks (12) are laterally shifted on either side of the said element (14).

Description

Caisse-palette en un matériau semi-rigide, utilisable comme système de distribution des objets ou matériaux qu'elle contient. Pallet box in a semi-rigid material, usable as a distribution system for the objects or materials it contains.

L'invention concerne les conditionnements du genre des caisses-palettes, en un matériau semi-rigide tel que le carton ondulé. Elle a plus particulièrement pour objet un conditionnement de ce type qui est directement utilisable comme système de distribution des objets ou matériaux conditionnés. The invention relates to packaging of the pallet box type, made of a semi-rigid material such as corrugated cardboard. It more particularly relates to a packaging of this type which is directly usable as a distribution system for the objects or materials packaged.

Les caisses-palettes auxquelles s s'intéresse la présente invention sont celles dans lesquelles des fourreaux longitudinaux parallèles, solidaires du fond d'un conteneur en carton, carton ondulé ou similaire, reçoivent des blocs de renfort en un matériau rigide ou semi-rigide, par exemple du polystyrène expansé, pour former une palette sous le conteneur et permettre ainsi de le transporter à l'aide de chariots de manutention à fourche. The pallet boxes in which the present invention is concerned are those in which parallel longitudinal sleeves, integral with the bottom of a cardboard, corrugated cardboard or similar container, receive reinforcement blocks made of a rigid or semi-rigid material, for example expanded polystyrene, to form a pallet under the container and thus allow it to be transported using forklift trucks.

Dans son brevet européen NO 231 135, la Demanderesse a ainsi proposé, par exemple une caisse-palette de ce type dont le conteneur est une caisse dite "américaine" et dans laquelle, en vue de permettre un pré-assemblage des différents constituants et le pliage à plat de la caissepalette ainsi pré-assemblée, les fourreaux sont constitués de deux demi-fourreaux, qui, après mise en volume de la caisse-palette, sont disposés bout à bout et solidaires respectivement, par l'intermédiaire desdites languettes, de volets externes constituant le fond de la caisse, chaque demi-fourreau recevant un bloc de renfort indépendant. In its European patent NO 231 135, the Applicant has thus proposed, for example a pallet box of this type whose container is a so-called "American" box and in which, in order to allow a pre-assembly of the various constituents and the flat folding of the pallet box thus pre-assembled, the sleeves consist of two half-sleeves, which, after the volume of the pallet box, are placed end to end and secured respectively, by means of said tongues, external flaps constituting the bottom of the box, each half-sheath receiving an independent reinforcement block.

Dans d'autres caisses-palettes de ce type, des demifourreaux sont fixés par collage ou agrafage sur la face externe des volets associés et un unique bloc de renfort est engagé dans deux fourreaux disposés dans le prolongement l'un de l'autre respectivement sur chacun des volets externes, en vue de verrouiller ces volets en position de fermeture. In other pallet boxes of this type, half-forks are fixed by gluing or stapling on the external face of the associated flaps and a single reinforcement block is engaged in two sleeves arranged in the extension of each other respectively on each of the external flaps, in order to lock these flaps in the closed position.

En poursuivant ses travaux sur ce type d'emballages, la Demanderesse a été amenée à concevoir des perfectionnements permettant d'utiliser ces conditionnements comme systèmes de distribution des objets ou des matériaux qu'ils contiennent. By continuing its work on this type of packaging, the Applicant has been led to design improvements enabling these packaging to be used as distribution systems for the objects or materials they contain.

En effet, dans de nombreuses industries, de petits objets, des pièces détachées et même des matériaux en vrac sont conditionnés dans des emballages de grandes dimensions et expédiés chez des utilisateurs, où ils sont retirés de leurs emballages en vue de leur stockage ou de leur utilisation. Les emballages sont en général simplement vidés dans une enceinte de stockage ou dans une trémie de distribution, à partir de laquelle ils alimentent en continu des chaînes de fabrication. Indeed, in many industries, small objects, spare parts and even bulk materials are packaged in large packages and shipped to users, where they are removed from their packaging for storage or storage. use. The packages are generally simply emptied into a storage enclosure or into a distribution hopper, from which they continuously supply production lines.

Ces opérations nécessitent naturellement la présence de surveillants et sont, par conséquent, génératrices de frais, qui grèvent le coût final des produits dans la fabrication ou la constitution desquels entrent les objets conditionnés. These operations naturally require the presence of supervisors and are, therefore, generating costs, which increase the final cost of the products in the manufacture or constitution of which the conditioned objects enter.

La présente invention vise à remédier à cet inconvénient en proposant un conditionnement, à partir duquel les objets conditionnés puissent être distribués directement et régulièrement, sans stockage intermédiaire. The present invention aims to remedy this drawback by proposing packaging, from which the packaged objects can be distributed directly and regularly, without intermediate storage.

L'invention a également pour but un conditionnement de ce type, qui puisse être réalisé par des procédés usuels, sans majoration du coût de fabrication. Another object of the invention is also a packaging of this type, which can be produced by usual methods, without increasing the manufacturing cost.

L'invention a enfin pour but un conditionnement de ce type qui puisse être fabriqué sous de grandes dimensions et avoir ainsi un volume important, en vue d'être utilisé comme une véritable trémie de distribution. The invention finally aims at a packaging of this type which can be manufactured in large dimensions and thus have a large volume, in order to be used as a real distribution hopper.

A cet effet, l'invention a pour objet une caissepalette en un matériau semi-rigide, du type dans lequel le fond comprend deux volets externe attenants respectivement par une ligne de pliage à deux parois parallèles, chaque volet portant sur sa face externe au moins trois fourreaux parallèles, perpendiculaires auxdites parois parallèles et disposés respectivement dans le prolongement des fourreaux associés à l'autre volet, un bloc de renfort de profil complémentaire en une matière rigide étant engagé dans les fourreaux disposés en regard pour verrouiller en position de fermeture les volets externes du fond et pour surélever la caisse-palette par rapport au support sur laquelle elle repose, cette caisse-palette étant caractérisée en ce que, dans l'un au moins desdits volets est découpé un élément formant trappe de vidange, monté pivotant autour d'une ligne de pliage par rapport audit volet, ladite partie formant trappe étant disposée de façon telle qu'elle soit maintenue en position dans le plan du volet associé par l'un desdits blocs de renfort et qu'elle puisse pivoter librement lorsque ce bloc est retiré, tandis que les deux autres blocs sont décalés latéralement de part et d'autre de ladite partie. To this end, the subject of the invention is a box pallet made of a semi-rigid material, of the type in which the bottom comprises two external flaps adjoining respectively by a fold line with two parallel walls, each flap bearing on its external face at least three parallel sheaths, perpendicular to said parallel walls and respectively disposed in the extension of the sheaths associated with the other flap, a reinforcing block of complementary profile in a rigid material being engaged in the sheaths arranged opposite to lock the flaps in the closed position external of the bottom and to raise the pallet box relative to the support on which it rests, this pallet box being characterized in that, in at least one of said flaps is cut an element forming a drain flap, pivotally mounted around '' a fold line relative to said flap, said hatch portion being arranged in such a way that it is held in position in the plane of the associated flap by one of said reinforcing blocks and that it can pivot freely when this block is removed, while the other two blocks are offset laterally on either side of said part.

Pour libérer cette partie formant trappe de vidange et permettre ainsi aux objets conditionnés de s'écouler librement à travers l'ouverture dégagée par son pivotement, il suffira donc de retirer le bloc de renfort qui la maintient en position, la caisse-palette continuant à reposer sur son support par les deux autres blocs de renfort et les fourreaux associés. To release this part forming the drain flap and thus allow the conditioned objects to flow freely through the opening released by its pivoting, it will therefore suffice to remove the reinforcement block which keeps it in position, the pallet box continuing to rest on its support by the two other reinforcement blocks and the associated sleeves.

La ligne de pliage par laquelle la partie formant trappe sera articulée sur le volet associé sera de préférence parallèle à la paroi à laquelle ce volet est attenant et un bord libre de cette partie sera constitué par une fraction du bord libre du volet parallèle à ladite paroi. The fold line by which the hatch part will be articulated on the associated flap will preferably be parallel to the wall to which this flap is attached and a free edge of this part will be constituted by a fraction of the free edge of the flap parallel to said wall. .

Avantageusement, deux parties identiques formant trappes de vidange seront ménagées symétriquement, une sur chacun des deux volets, de façon à dégager, après pivotement de ces parties, une unique ouverture de vidange. Advantageously, two identical parts forming emptying hatches will be arranged symmetrically, one on each of the two flaps, so as to release, after pivoting of these parts, a single emptying opening.

Afin que cette ouverture ait des dimensions suffisantes, la ligne de pliage par laquelle lesdites parties pivotantes sont articulées sur les volets associés seront aussi proches que possible du bord de la paroi correspondante à laquelle les fourreaux sont perpendiculaires, ce qui amènera à raccourcir ceux dans lesquels est engagé le bloc de renfort qui maintient ces parties pivotantes, par rapport aux fourreaux dans lesquels sont engagés les blocs servant de support. So that this opening has sufficient dimensions, the fold line by which said pivoting parts are articulated on the associated flaps will be as close as possible to the edge of the corresponding wall to which the sleeves are perpendicular, which will lead to shorten those in which is engaged the reinforcement block which maintains these pivoting parts, relative to the sleeves in which the blocks serving as support are engaged.

Avantageusement, à l'intérieur de la caisse-palette seront prévues, au voisinage du fond, à partir des parois latérales, des éléments inclinés en direction de l'ouverture définie par les parties formant trappes de vidange ménagées dans les volets, afin de favoriser une évacuation régulière des objets conditionnés. Ces éléments seront par exemple attenants aux parois et rapportés sur celles-ci. Advantageously, inside the pallet box will be provided, in the vicinity of the bottom, from the side walls, elements inclined in the direction of the opening defined by the parts forming emptying hatches formed in the flaps, in order to favor regular evacuation of packaged items. These elements will for example be attached to the walls and attached to them.

Les volets externes pourront être doublés intérieurement, de façon usuelle, par des volets internes attenants aux parois autres que celles sur lesquelles sont articulés les volets externes, leurs dimensions étant telles, bien entendu, qu'ils n'obstruent pas l'ouverture définie par les parties pivotantes formant trappes de vidange. La partie des éléments inclinés attenants aux mêmes parois que les volets internes pourra avantageusement comporter une extrémité repliée au-dessous des volets internes et pincée entre ceux-ci et les volets externes. Les autres éléments inclinés seront disposés audessous des précédents et maintenus en position par ceuxci. The external flaps may be doubled internally, in the usual way, by internal flaps adjoining the walls other than those on which the external flaps are articulated, their dimensions being such, of course, that they do not obstruct the opening defined by the pivoting parts forming drain doors. The part of the inclined elements adjoining the same walls as the internal flaps may advantageously have one end folded back below the internal flaps and pinched between them and the external flaps. The other inclined elements will be arranged below the previous ones and held in position by them.

D'autres caractéristiques et avantages de l'invention apparaltront ci-après dans la description détaillée qui va être donnée d'une forme de réalisation d'une telle caissepalette. Dans cette description, on se réfèrera aux dessins annexés, sur lesquels:
La figure 1 est une vue en perspective, avec arrachement, de cette caisse-palette;
La figure 2 est une vue de dessous de la caissepalette;
La figure 3 est une vue schématique de détail illustrant la position de certains éléments inclinés en direction de l'ouverture définie par les parties pivotantes ménagées dans les volets externes du fond.
Other characteristics and advantages of the invention will appear below in the detailed description which will be given of an embodiment of such a box pallet. In this description, reference will be made to the appended drawings, in which:
Figure 1 is a perspective view, with parts broken away, of this pallet box;
Figure 2 is a bottom view of the pallet box;
Figure 3 is a schematic detail view illustrating the position of certain elements inclined towards the opening defined by the pivoting parts formed in the outer flaps of the bottom.

Comme représenté sur les dessins, cette caissepalette est d'un type double, connu en soi, c'est-à-dire qu'elle comporte deux corps de conteneur en carton ondulé, l'un supérieur , 1 l'autre inférieur 2, ayant la forme générale de parallélépipèdes rectangles de même section. As shown in the drawings, this pallet box is of a double type, known per se, that is to say that it comprises two container bodies of corrugated cardboard, one upper, 1 the other lower 2, having the general shape of rectangular parallelepipeds of the same section.

Le corps supérieur 1 présente à sa base des bandes 3, repliées perpendiculairement à ses parois latérales et par lesquelles il prend appui sur des bandes 4 repliées à la partie supérieure du corps 2, perpendiculairement aux parois de celui-ci. Les deux conteneurs communiquent l'un avec Autre par les ouvertures définies par les bandes 3 et 4, et l'une des bandes 3 est solidaire, par collage ou agrafage, de la bande 4 associée, de manière que le corps supérieur 1 puisse basculer par rapport au corps inférieur 2. Entre les deux corps est montée coulissante une plaque 5, formant trappe de séparation, qui est munie d'une poignée de préhension 6.The upper body 1 has at its base bands 3, folded perpendicular to its side walls and by which it bears on bands 4 folded at the upper part of the body 2, perpendicular to the walls thereof. The two containers communicate with each other through the openings defined by the bands 3 and 4, and one of the bands 3 is secured, by gluing or stapling, to the associated band 4, so that the upper body 1 can tilt relative to the lower body 2. Between the two bodies is slidably mounted a plate 5, forming a separation hatch, which is provided with a grip handle 6.

Le conteneur inférieur 2 est fermé à sa base par deux volets externes 7 (voir Figure 2), attenants par des lignes de pliage à deux parois parallèles 8 et doublés intérieurement, sur une partie de leur surface, par deux volets internes 9 attenants aux deux autres parois 10. The lower container 2 is closed at its base by two external flaps 7 (see Figure 2), adjoining by fold lines with two parallel walls 8 and lined internally, over part of their surface, by two internal flaps 9 adjoining the two other walls 10.

Sur chacun des volets externes 7 sont fixés, par collage, par agrafage ou par un autre moyen, au voisinage des bords latéraux de ces volets, deux fourreaux 11 à section carrée ou rectangulaire. Ces fourreaux 11 sont perpendiculaires aux parois 8 et sont disposés sur les volets 7 de façon telle qu'ils soient deux à deux dans le prolongement les uns des autres. Il est ainsi possible d'engager dans deux fourreaux, solidaires respectivement dans deux volets 7 et disposés en regard l'un de l'autre, un unique bloc de renfort rigide 12, qui, avec les fourreaux associés, forme un piètement pour la caissepalette et maintient en position de fermeture, dans un même plan, les deux volets 7. On each of the external flaps 7 are fixed, by gluing, stapling or by other means, in the vicinity of the lateral edges of these flaps, two sleeves 11 with square or rectangular section. These sleeves 11 are perpendicular to the walls 8 and are arranged on the flaps 7 so that they are two by two in the extension of each other. It is thus possible to engage in two sleeves, respectively secured in two flaps 7 and arranged opposite one another, a single rigid reinforcement block 12, which, with the associated sleeves, forms a base for the box pallet and maintains in the closed position, in the same plane, the two flaps 7.

Conformément à l'invention, dans la partie médiane de ces volets sont découpées, symétriquement par rapport aux bords contigus des volets, deux parties 14, articulées sur le volet correspondant par une ligne de pliage 15 parallèle aux parois 8. Ces parties 14 sont maintenues dans le plan des volets 7 par un bloc de renfort 16 analogue aux blocs 13 et engagés comme ceux-ci dans deux fourreaux 17, perpendiculaires aux parois 8 et fixés sur les volets 7 depuis les lignes de pliage 15 jusqu'à ces parois 8. According to the invention, in the middle part of these flaps are cut, symmetrically with respect to the contiguous edges of the flaps, two parts 14, articulated on the corresponding flap by a fold line 15 parallel to the walls 8. These parts 14 are held in the plane of the flaps 7 by a reinforcement block 16 similar to the blocks 13 and engaged like these in two sleeves 17, perpendicular to the walls 8 and fixed to the flaps 7 from the fold lines 15 to these walls 8.

En retirant le bloc 16 des fourreaux 17, on libère ainsi les parties 14, qui, sous le poids des articles contenus dans la caisse-palette, ou sous une sollicitation extérieure, pivotent autour des lignes 15, en dégageant ainsi une ouverture de vidange, par laquelle sont distribués les articles conditionnés. By removing the block 16 from the sleeves 17, the parts 14 are freed, which, under the weight of the articles contained in the pallet box, or under an external stress, pivot around the lines 15, thereby freeing up a drain opening, by which the conditioned articles are distributed.

Le conteneur se vide ainsi des articles qu'il contient à la manière d'une véritable trémie et l'utilisateur peut l'utiliser directement sur des channes de fabrication ou d'équipement de produits, dans la constitution desquels entrent lesdits objets. The container thus empties of the articles it contains in the manner of a real hopper and the user can use it directly on production lines or product equipment, in the constitution of which enter said objects.

Dans le cas présent, les deux conteneurs 1 et 2 peuvent être vidés successivement ou simultanément, mais l'invention n'est pas limitée, bien entendu, à ce genre de réalisation et elle s'applique naturellement à une caissepalette comportant un unique conteneur. In the present case, the two containers 1 and 2 can be emptied successively or simultaneously, but the invention is not limited, of course, to this kind of embodiment and it naturally applies to a box pallet comprising a single container.

Afin de favoriser l'utilisation de la caisse-palette conforme à l'invention comme trémie de distribution, des éléments 20 et 21, fixés respectivement à la partie inférieure de la face interne des parois 8 et 10 et montés pivotants par rapport à ces parois, seront inclinés en direction de l'ouverture définie par les parties pivotantes 14 formant trappe. Les éléments 20 attenants aux parois 8 pourront avoir une forme rectangulaire, tandis que les éléments 21 attenants aux parois 10 prendront appui sur les précédents et auront, vus de dessus, la forme d'un triangle ou d'un trapèze dont l'extrémité contiguë aux parties 14 sera repliée audessous des volets internes 9 et pincée entre ceux-ci et les volets externes 7, de façon à assurer ainsi le verrouillage en position de l'ensemble des éléments inclinés. In order to favor the use of the pallet box according to the invention as a distribution hopper, elements 20 and 21, fixed respectively to the lower part of the internal face of the walls 8 and 10 and mounted so as to pivot relative to these walls , will be inclined towards the opening defined by the pivoting parts 14 forming a hatch. The elements 20 adjoining the walls 8 may have a rectangular shape, while the elements 21 adjoining the walls 10 will bear on the preceding ones and will, seen from above, have the shape of a triangle or a trapezoid whose contiguous end to the parts 14 will be folded below the internal flaps 9 and pinched between them and the external flaps 7, so as to thus ensure the locking in position of all of the inclined elements.

L'invention apporte donc un progrès important dans la technique des caisses-palettes en permettant à celles-ci d'être utilisées directement comme système de distribution des articles ou matériaux qu'elles contiennent.  The invention therefore provides significant progress in the technique of pallet boxes by allowing them to be used directly as a distribution system for the articles or materials they contain.
