Abstract

This container for waste consists of a cardboard box (100). An inner envelope (200) is intended to receive the waste and its upper part is held in an opening made in the upper flap (51-54) which is folded down first. At least one of the upper flaps includes a closure and support (bearing) tab (71,74) at its end, intended to interact with the opposite face of the container. Once filled, the inner envelope (200) is closed by means of a tie and all the upper flaps are folded down. The upper flap (52) which is folded down last includes a tab (72) capable of being inserted between the flaps (51,53,54) which have already been folded down and the opposite face (4) of the cardboard box. This tab includes a slot (721) capable of receiving a detachable safety locking tab (442) of the opposite wall (4). <IMAGE>

Description

L'invention est du domaine des récipients pour déchets et concerne plus particulièrement des cartonnages pliables.The invention is in the field of waste containers and relates more particularly to foldable cardboard boxes.

Pour éviter autant que possible tout contact entre des déchets toxiques et la personne devant les manipuler, on a déjà proposé de disposer ceux-ci dans un sac plastique, sac qui sera encore disposé dans un cartonnage qui, une fois refermé, permettra de manipuler le tout sans danger.To avoid as much as possible any contact between toxic waste and the person having to handle it, it has already been proposed to dispose of this in a plastic bag, a bag which will still be placed in a carton which, once closed, will allow handling the all safe.

La présente invention propose d'améliorer ce type de réalisations et a pour objet un récipient pour déchets constitué par un cartonnage, de forme générale parallélipipédique, dont les faces latérales présentent dans leur partie inférieure des rabats sur des lignes de pliure inférieure, ainsi que dans leur partie supérieure des rabats sur des lignes de pliure supérieure supérieures, et par une enveloppe intérieure.The present invention proposes to improve this type of embodiment and relates to a container for waste consisting of cardboard, of generally parallelepiped shape, the lateral faces of which have in their lower part flaps on lower fold lines, as well as in their upper part of the flaps on upper upper fold lines, and by an inner envelope.

Ce récipient est caractérisé par le fait que :

  • au moins l'un des rabats supérieurs comporte une ouverture d'introduction des déchets dans l'enveloppe intérieure,
  • au moins l'un des rabats supérieurs comporte des moyens de fixation du haut de l'enveloppe dans l'ouverture,
  • au moins l'un des rabats supérieurs comporte à son extrémité une languette de fermeture et d'appui destinée à coopérer avec la face opposée du récipient.
This container is characterized by the fact that:
  • at least one of the upper flaps has an opening for introducing waste into the inner envelope,
  • at least one of the upper flaps comprises means for fixing the top of the envelope in the opening,
  • at least one of the upper flaps has at its end a closure and support tab intended to cooperate with the opposite face of the container.

Dans une forme d'exécution préférentielle, tous les rabats supérieurs du cartonnage s'étendent jusqu'à la face du cartonnage qui leur est opposée et sont munis de moyens de fixation à celle-ci. En outre un dispositif de verrouillage permet de bloquer les rabats lorsque le récipient est plein et doit être manipulé.In a preferred embodiment, all of the upper flaps of the carton extend to the opposite side of the carton and are provided with means of attachment thereto. In addition, a locking device makes it possible to block the flaps when the container is full and must be handled.

Le dessin annexé représente, à titre d'exemple non limitatif, une forme d'exécution de l'objet de la présente invention.The appended drawing represents, by way of nonlimiting example, an embodiment of the object of the present invention.

La figure 1 est une vue de dessus du découpage à réaliser pour obtenir un cartonnage selon l'invention.Figure 1 is a top view of the cutting to achieve to obtain a carton according to the invention.

La figure 2 est une vue du cartonnage tel qu'il se présente, en perspective, au cours de l'introduction de déchets.Figure 2 is a view of the carton as it appears, in perspective, during the introduction of waste.

La figure 3 est une vue partielle en coupe selon la ligne III-III du cartonnage de la figure 2.Figure 3 is a partial sectional view along line III-III of the carton of Figure 2.

La figure 4 est une vue partielle en coupe selon la ligne IV-IV du cartonnage de la figure 2.FIG. 4 is a partial sectional view along line IV-IV of the carton of FIG. 2.

La figure 5 est une coupe transversale correspondant à la vue de la figure 4, dans la position de fermeture du cartonnage, une fois que tous les déchets sont enfermés dans une enveloppe protectrice intérieure.Figure 5 is a cross section corresponding to the view of Figure 4, in the closed position of the carton, once all the waste is enclosed in an inner protective envelope.

Le découpage 100 représenté à la figure 1 en plan est destiné à la confection d'un cartonnage tubulaire ayant une section sensiblement carrée. Il comporte ainsi quatre côtés 1 à 4, ainsi qu'une bande latérale de fermeture 5, séparés par des lignes de pliure verticales 11 à 14, représentées en traitillés, constituant des arêtes entre les faces 1 à 4. Vers le bas les côtés 1 à 4 sont terminés par quatre rabats inférieurs 21 à 24, séparés par des fentes 25 à 27 et situés au-delà de lignes de pliure horizontales 31 à 34.The cutout 100 shown in FIG. 1 in plan is intended for making tubular cardboard having a substantially square section. It thus has four sides 1 to 4, as well as a lateral closure strip 5, separated by vertical fold lines 11 to 14, shown in dotted lines, constituting edges between the faces 1 to 4. Down the sides 1 to 4 are terminated by four lower flaps 21 to 24, separated by slots 25 to 27 and located beyond horizontal fold lines 31 to 34.

On notera que les rabats inférieurs 21 à 24 sont de forme générale carrée ce qui permet de les superposer lorsque le cartonnage est monté, de manière à créer une base plus solide encore. On a schématisé au dessin des bandes autocollantes 28 et 29, sur l'envers du rabat 22 et sur le dessus du rabat 24, permettant l'assemblage du cartonnage, comme on le verra par la suite.Note that the lower flaps 21 to 24 are of generally square shape which allows them to be superimposed when the cardboard is assembled, so as to create an even more solid base. We have shown diagrammatically in the drawing self-adhesive strips 28 and 29, on the back of the flap 22 and on the top of the flap 24, allowing the assembly of the cardboard, as will be seen below.

Des lignes de pliures horizontales 41 à 44 sont réalisées au sommet des côtés 1 à 4 et sont représentées en traitillés au dessin et constituant les arêtes entre les faces et le dessus du récipient. On notera que les lignes de pliures 31 à 34 et 41 à 44 ne sont pas situées sur une même droite, car on a représenté au dessin avec exagération la nécessité d'avoir des différences de hauteurs de pliure pour compenser l'épaisseur des rabats repliés précédemment.Horizontal fold lines 41 to 44 are made at the top of the sides 1 to 4 and are shown in dashed lines in the drawing and constituting the edges between the faces and the top of the container. It will be noted that the fold lines 31 to 34 and 41 to 44 are not located on the same straight line, because the drawing has been shown with exaggeration the need to have differences in fold heights to compensate for the thickness of the folded flaps previously.

Des découpages particuliers sont prévus le long des lignes de pliures 41 à 44, qui vont être décrits en détail.Particular cutouts are provided along the fold lines 41 to 44, which will be described in detail.

Le long de la pliure 41 sont prévues deux découpes 411 et 412, destinées à réaliser des fentes dans cette arête une fois que le rabat 51 est replié le long de la ligne de pliure 41.Along the fold 41, two cutouts 411 and 412 are provided, intended to make slots in this edge once the flap 51 is folded along the fold line 41.

Le long des pliures 42 et 43 on prévoit des fentes horizontales 421 et 431. Chaque fente 421 (ou 431) définit un rebord 422 (ou 432) au centre de la face 2 (ou 3) du cartonnage. Chaque fente est prolongée vers le bas à ses extrémités par deux dégagements arrondis 423 et 424 (ou 433 et 434). Dans sa partie centrale, chaque fente s'ouvre sur une découpe semi-circulaire 425 (ou 435). L'utilité de ces détails sera mentionnée dans la description du processus de fermeture du cartonnage.Along the folds 42 and 43, horizontal slots 421 and 431 are provided. Each slot 421 (or 431) defines a flange 422 (or 432) at the center of the face 2 (or 3) of the carton. Each slot is extended downward at its ends by two rounded clearances 423 and 424 (or 433 and 434). In its central part, each slot opens onto a semi-circular cut 425 (or 435). The usefulness of these details will be mentioned in the description of the carton closure process.

On remarquera dans la pliure 44, une ligne 441 de pré-perforage définissant une languette 442, qui peut être détachée et repliée parallèlement à la pliure 44 le long d'une ligne 443. A l'extrémité 444 de la languette 442, une découpe semi-circulaire 445 permet de détacher plus facilement la languette. Deux fentes 446 et 447 sont prévues le long de la ligne de pliure 44, de part et d'autre de la languette 442.Note in the fold 44, a line 441 of pre-perforation defining a tongue 442, which can be detached and folded parallel to the fold 44 along a line 443. At the end 444 of the tongue 442, a cutout semi-circular 445 makes it easier to detach the tab. Two slots 446 and 447 are provided along the fold line 44, on either side of the tongue 442.

Ces lignes de pliures 41 à 44 permettent de former des rabats supérieurs 51 à 54, séparés par des fentes 55 à 57.These fold lines 41 to 44 make it possible to form upper flaps 51 to 54, separated by slots 55 to 57.

Dans la variante représentée au dessin, le découpage particulier des rabats supérieurs 51 à 54 est étudié pour constituer :

  • 1. au cours de la phase d'introduction des déchets, une fixation efficace d'une enveloppe plastique destinée à contenir les déchets ,
  • 2. une fermeture sûre du récipient lorsqu'il est rempli et doit être transporté.
In the variant shown in the drawing, the particular cutting of the upper flaps 51 to 54 is studied to constitute:
  • 1. during the waste introduction phase, efficient fixing of a plastic envelope intended to contain the waste,
  • 2. a secure closure of the container when it is filled and must be transported.

Le rabat 51 comporte une ouverture centrale 511 présentant une forme générale octogonale. Les deux côtés libres du rabat 51 comportent des bandes adhésives 512 et 513, recouvertes de bandes protectrices tant qu'elles ne sont pas utilisées pour maintenir le haut du sac plastique au cours de son remplissage. Un dégagement latéral 514 est prévu pour des raisons explicitées dans la suite de cette description. Le rabat 51 comporte encore, en deçà d'une ligne de pliure 61 parallèle aux lignes 31 et 41 déjà mentionnées, une languette de fermeture et d'appui 71. Plus précisément cette languette 71 comporte une partie centrale 711 faisant saillie entre deux découpes arrondies 712 et 713 dont l'utilité sera mentionnée plus loin.The flap 51 has a central opening 511 having a generally octagonal shape. The two free sides of the flap 51 have adhesive strips 512 and 513, covered with protective strips as long as they are not used to hold the top of the plastic bag during its filling. A lateral clearance 514 is provided for reasons explained in the remainder of this description. The flap 51 also comprises, below a fold line 61 parallel to the lines 31 and 41 already mentioned, a closure and support tongue 71. More precisely, this tongue 71 has a central part 711 projecting between two rounded cutouts 712 and 713, the usefulness of which will be mentioned later.

Le rabat 52 est plein. Il comporte vers le haut une languette de fermeture centrale 72 d'une largeur inférieure à la distance entre les fentes 446 et 447 décrites précédemment. Au centre de la languette 72, au niveau d'une pliure 62, une fente 721 est prévue pour recevoir la languette 442 détachable du côté 4. Une ouverture semi-circulaire 722 s'ouvre dans le rabat 52.The flap 52 is full. It comprises upwards a central closing tab 72 with a width less than the distance between the slots 446 and 447 described above. At the center of the tongue 72, at a fold 62, a slot 721 is provided to receive the tongue 442 detachable from the side 4. A semi-circular opening 722 opens in the flap 52.

Le rabat 53 est plein et présente un dégagement latéral 531, pour des raisons explicitées dans la suite de cette description. Le rabat 53 se termine vers l'extérieur par deux languettes 731 et 732 dimensionnées pour être engagées à force dans les fentes 411 et 412 déjà mentionnées le long de la pliure 41. On notera la forme trapézoïdale de ces languettes, destinées à les retenir dans les fentes 411 et 412.The flap 53 is full and has a lateral clearance 531, for reasons explained in the remainder of this description. The flap 53 ends outwards with two tabs 731 and 732 sized for be forced into the slots 411 and 412 already mentioned along the fold 41. Note the trapezoidal shape of these tongues, intended to retain them in the slots 411 and 412.

Le rabat 54 comporte des pré-perforations 541 permettant d'y dégager un clapet 542. Une ouverture semi-circulaire 543 permet à l'utilisateur de dégager plus facilement le clapet 542 qui peut être articulé le long de la ligne de pliure 544. Le rabat 54 comporte encore, en deçà d'une ligne de pliure 64 parallèle aux lignes 34 et 44 déjà mentionnées, une languette de fermeture et d'appui 74. Plus précisément cette languette 74 comporte une partie centrale 741 faisant saillie entre deux découpes arrondies 742 et 743 dont l'utilité sera mentionnée plus loin.The flap 54 has pre-perforations 541 allowing a valve 542 to be released therein. A semi-circular opening 543 allows the user to more easily release the valve 542 which can be articulated along the fold line 544. The flap 54 further includes, below a fold line 64 parallel to lines 34 and 44 already mentioned, a closure and support tongue 74. More precisely, this tongue 74 has a central part 741 projecting between two rounded cutouts 742 and 743, the usefulness of which will be mentioned later.

Le cartonnage selon l'invention est monté en réunissant les côtés 1 et 4 au moyen de la bande latérale 5 fixée de manière connue par collage ou agrafage. Il est à noter que l'on peut alors stocker les cartonnages, pliés en deux, soit sur deux des lignes de pliure 11 à 14, soit le long de lignes passant par les côtés 1 et 3 ou 2 et 4.The cardboard according to the invention is mounted by joining the sides 1 and 4 by means of the side strip 5 fixed in a known manner by gluing or stapling. It should be noted that the cardboard boxes can then be stored, folded in half, either on two of the fold lines 11 to 14, or along lines passing through the sides 1 and 3 or 2 and 4.

Avant d'être utilisé, le récipient est déployé et les rabats inférieurs 23, 21, 24 et 22 sont successivement repliés le long des lignes 31 à 34. Le rabat 24 est fixé au rabat 22 par les bandes autocollantes 28 et 29.Before being used, the container is deployed and the lower flaps 23, 21, 24 and 22 are successively folded along the lines 31 to 34. The flap 24 is fixed to the flap 22 by the adhesive strips 28 and 29.

Les étapes de préparation du haut du récipient sont les suivantes. Le rabat 51 est le premier être replié vers l'intérieur, ainsi que la languette 71. On notera dans la coupe de la figure 3 que la partie centrale 711 de la languette 71 est passée dans la fente 431 de manière à ce que le rabat 51 repose sur le rebord d'appui 432 situé au haut de la face 3 du carton, les découpes arrondies 712 et 713 venant s'engager respectivement contre les dégagements 433 et 434.The steps for preparing the top of the container are as follows. The flap 51 is the first to be folded inwards, as is the tongue 71. note in the section of FIG. 3 that the central part 711 of the tongue 71 has passed through the slot 431 so that the flap 51 rests on the support flange 432 situated at the top of the face 3 of the carton, the rounded cutouts 712 and 713 engaging respectively against clearances 433 and 434.

Un sac plastique 200 est alors disposé à l'intérieur du récipient. Sa partie supérieure passe dans l'ouverture centrale 511 et est fixée sur le rabat 51 au moyen des bandes adhésives 512 et 513. Le rabat 54 est alors refermé, la languette 74 étant maintenue sur le rebord d'appui 422 comme on l'a vu pour la languette 71 sur le rebord 432. Les dégagements 423 et 424 supportent également le rabat 54, et plus précisément ses découpes arrondies 742 et 743. Grâce à ce système d'appui on obtient un cartonnage solide, dont la partie supérieure reste parfaitement horizontale et ne risque pas d'être défoncée vers le bas. Pour assurer la rigidité de la face supérieure du cartonnage, on a avantage à ce que les rebords d'appui 422 et 433 soient prévus le long de deux faces adjacentes, pour assurer le croisement des rabats porteurs.A plastic bag 200 is then placed inside the container. Its upper part passes through the central opening 511 and is fixed to the flap 51 by means of the adhesive strips 512 and 513. The flap 54 is then closed, the tongue 74 being held on the support flange 422 as was seen for the tongue 71 on the flange 432. The clearances 423 and 424 also support the flap 54, and more precisely its rounded cutouts 742 and 743. Thanks to this support system, solid cardboard is obtained, the upper part of which remains perfectly horizontal and is not likely to be knocked down. To ensure the rigidity of the upper face of the carton, it is advantageous for the support flanges 422 and 433 to be provided along two adjacent faces, to ensure the crossing of the carrying flaps.

Il est avantageux que l'enveloppe intérieure 200 reste visible, comme représenté à la figure 2, en raison des dimensions croissantes de l'ouverture 511 et du clapet 542, car ceci permet d'une part de s'assurer de la présence d'un sac plastique, et d'autre part de maintenir ce dernier entre les rabats 51 et 54.It is advantageous that the inner envelope 200 remains visible, as shown in FIG. 2, because of the increasing dimensions of the opening 511 and of the valve 542, because this allows on the one hand to ensure the presence of a plastic bag, and on the other hand to maintain the latter between the flaps 51 and 54.

L'utilisateur peut alors détacher le clapet 542 le long de la ligne des perforations 541 et le replier vers l'arrière comme représenté à la figure 2 qui représente la position dans laquelle les déchets sont introduits. Le clapet 542, partiellement représenté au dessin, permet de refermer le récipient au cours de son remplissage.The user can then detach the valve 542 along the line of the perforations 541 and fold it back as shown in FIG. 2 which represents the position in which the waste is introduced. The valve 542, partially shown in the drawing, allows the container to be closed during filling.

La vue de la figure 3 indique, comme on l'a déjà mentionné, le système d'appui du rabat 51 sur le rebord 432. A la figure 4, on remarque comment le haut du sac 200 traverse le rabat 51 avant d'être fixé le long des bandes adhésives 512 et 513. On voit également l'appui de la languette 74 sur le rebord 422.The view in FIG. 3 indicates, as already mentioned, the support system for the flap 51 on the flange 432. In FIG. 4, we note how the top of the bag 200 crosses the flap 51 before being fixed along the adhesive strips 512 and 513. We also see the support of the tongue 74 on the flange 422.

On veillera à ne pas trop remplir l'enveloppe intérieure pour pouvoir refermer le sac plastique 200 par un lien, comme représenté à la figure 5, après avoir rouvert temporairement le rabat 54. Il est à noter que c'est pour permettre un accès aisé aux languettes centrales 711 et 741 que des ouvertures arrondies 425 et 435 sont prévues dans les rabats 52 et 53.Take care not to overfill the inner envelope to be able to close the plastic bag 200 with a link, as shown in Figure 5, after having temporarily reopened the flap 54. Note that this is to allow easy access to the central tabs 711 and 741 that rounded openings 425 and 435 are provided in the flaps 52 and 53.

Le sac plastique 200 étant fermé par un lien, le rabat 54 est replié comme décrit précédemment après que la languette de sécurité 442 ait été détachée le long des perforations 441 et repliée vers l'extérieur le long de la ligne de pliure 443.The plastic bag 200 being closed by a link, the flap 54 is folded as described above after the safety tab 442 has been detached along the perforations 441 and folded outwards along the fold line 443.

Le rabat 53 est alors replié et les languettes trapézoïdales 731 et 732 sont engagées à force dans les fentes 411 et 412.The flap 53 is then folded back and the trapezoidal tabs 731 and 732 are forced into the slots 411 and 412.

Finalement le rabat 52 est replié et la languette centrale 72 est engagée dans l'espace libéré par le retrait de la languette 442, entre les fentes 446 et 447. La languette 72 est engagée entre la face 4 du carton et les rabats supérieurs 51 et 53, plus précisément leurs dégagements latéraux 514 et 531.Finally the flap 52 is folded and the central tongue 72 is engaged in the space freed by the withdrawal of the tongue 442, between the slots 446 and 447. The tongue 72 is engaged between the face 4 of the cardboard and the upper flaps 51 and 53, more precisely their lateral clearances 514 and 531.

Pour éviter que les rabats ne s'ouvrent intempestivement au cours des manipulations de transport du récipient selon l'invention, la languette de sécurité 442 est finalement introduite dans la fente 721, comme représenté à la figure 5. Elle permet de bloquer les différents rabats 51 à 54 car elle est engagée dans la fente 721 du rabat 52 et se trouve au-dessus des autres rabats. L'ouverture semi-circulaire 722 permet de retirer la languette 442, en cas de besoin.To prevent the flaps from opening inadvertently during the container handling manipulations according to the invention, the safety tab 442 is finally inserted into the slot 721, as shown in FIG. 5. It makes it possible to block the various flaps 51 to 54 because it is engaged in the slot 721 of the flap 52 and is located above the other flaps. The semicircular opening 722 allows the tab 442 to be removed, if necessary.

Les rabats 52 et 53 sont représentés aux figures 2 à 4 relevés vers le haut pour mieux montrer leur emplacement. Il va de soit que ces rabats peuvent également être disposés le long des faces 2 et 3 du carton, qui peuvent comprendre des moyens de fixation de ces rabats, constitués par exemple par des bandes collantes.The flaps 52 and 53 are shown in Figures 2 to 4 raised up to better show their location. It goes without saying that these flaps can also be arranged along the faces 2 and 3 of the carton, which may include means for fixing these flaps, constituted for example by adhesive strips.
