Description

Domaine techniqueTechnical area

Le domaine de l'invention est celui du transport de marchandises, et notamment du transport de marchandises.The field of the invention is that of the transport of goods, and in particular of the transport of goods.

Plus particulièrement, l'invention concerne une caisse, ou contenant, pour le transport de marchandises qui peuvent, par exemple, être des marchandises périssables, des flacons vides, des barquettes thermoformées, permettant de limiter la contamination de stocks et de faciliter le transport.More particularly, the invention relates to a box, or container, for the transport of goods which can, for example, be perishable goods, empty bottles, thermoformed trays, making it possible to limit the contamination of stocks and to facilitate transport.

L'invention concerne également un procédé d'obtention d'une caisse à partir d'un flan de carton, ainsi qu'un flan de carton correspondant.The invention also relates to a method for obtaining a box from a cardboard blank, as well as a corresponding cardboard blank.

Art antérieurPrior art

Pour le transport de marchandises, telle que des marchandises périssables, on connaît déjà des caisses de transports formées en carton comprenant au moins un fond, quatre côtés, ainsi que des renforts placés dans les angles entre les côtés consécutifs. Ces renforts sont, de manière classique, collés sur le côté adjacent au côté portant ce renfort de sorte à former un ensemble relativement résistant.For the transport of goods, such as perishable goods, there are already known transport boxes formed from cardboard comprising at least one bottom, four sides, as well as reinforcements placed in the angles between the consecutive sides. These reinforcements are conventionally glued to the side adjacent to the side carrying this reinforcement so as to form a relatively strong assembly.

Ces caisses de transport doivent, d'une part, résister à la compression lors de l'empilement d'une multitude de caisses, et d'autre part, les piles formées doivent être relativement stables, notamment durant le transport.These transport boxes must, on the one hand, resist compression during the stacking of a multitude of boxes, and on the other hand, the stacks formed must be relatively stable, in particular during transport.

De ce fait, de telles caisses présentent également, sur au moins deux côtés, des mortaises ainsi que des tenons permettant de former des piles de caisses par placement des mortaises de la caisse au niveau de tenons correspondants d'une caisse placée en dessous. Ces mortaises sont, de manières classiques formées par découpe dans le fond de la caisse tandis que les tenons sont formés au niveau des angles de la caisse de sorte que, lors d'un empilement de caisses fait par un opérateur, cet empilement manuel est facilité et s'avère relativement stable. En outre, durant le transport, de telles caisses présentent l'avantage de bien être fixées les unes aux autres et de limiter les risques de glisse.As a result, such boxes also have, on at least two sides, mortises as well as tenons making it possible to form stacks of boxes by placing the mortises of the box at the level of corresponding tenons of a box placed below. These mortises are, in conventional ways formed by cutting in the bottom of the box while the tenons are formed at the corners of the box so that, when stacking boxes by an operator, this manual stacking is facilitated. and turns out to be relatively stable. In addition, during transport, such boxes have the advantage of being well fixed to each other and of limiting the risk of slipping.

Toutefois, un inconvénient de ce type de caisses est qu'elles comportent des trous dans le fond ce qui pourrait, par exemple, provoquer des fuites de produits ou une contamination du produit contenu dans la caisse ce qui n'est pas satisfaisant. En effet, notamment pour des soucis d'hygiène et de traçabilité, il est nécessaire que les produits contenus dans une caisse ne puissent pas entrer en contact avec d'autres produits stockés à proximité. Il est également nécessaire, pour des raisons d'hygiène, que les produits contenus dans les caisses soient bien isolés de l'environnement extérieur et ne puissent pas entrer en contact, par exemple avec les parois du camion de transport ou les palettes de transport.However, a drawback of this type of crates is that they have holes in the bottom which could, for example, cause product leaks or contamination of the product contained in the crate, which is not satisfactory. Indeed, in particular for hygiene and traceability concerns, it is necessary that the products contained in a crate cannot come into contact with other products stored nearby. It is also necessary, for for hygienic reasons, that the products contained in the boxes are well isolated from the external environment and cannot come into contact, for example with the walls of the transport truck or the transport pallets.

Pour remédier à cet inconvénient, on connaît également des caisses présentant un fond sans trou ainsi que quatre côtés maintenus entre eux par le biais de renforts placés dans les angles. Ces caisses peuvent par exemple présenter une forme rectangulaire tronconique et s'empiler par appui sur les quatre côtés.To remedy this drawback, boxes are also known having a bottom without a hole as well as four sides held together by means of reinforcements placed in the corners. These boxes can, for example, have a frustoconical rectangular shape and can be stacked by resting on the four sides.

L'inconvénient des caisses tronconiques sans trou dans le fond et sans mortaises est qu'elles peuvent se déplacer latéralement quand elles sont empilées, ce qui donne lieu à une pile qui n'est pas stable.The downside of tapered boxes with no bottom hole and no mortises is that they can move sideways when stacked, resulting in a stack that is not stable.

Par ailleurs, il est relativement difficile d'automatiser la réalisation de telles piles de caisses du fait de leur manque de stabilité.Furthermore, it is relatively difficult to automate the production of such stacks of boxes due to their lack of stability.

Ainsi, il existe un besoin d'améliorer la technique existante de sorte à pallier au moins en partie les inconvénients de l'art antérieur.Thus, there is a need to improve the existing technique so as to at least partially overcome the drawbacks of the prior art.

Exposé de l'inventionDisclosure of the invention

L'invention répond à ce besoin en proposant une caisse pour le transport, notamment pour le transport de marchandises, ladite caisse comprenant un fond rectangulaire, à partir duquel s'étendent des parois latérales sur la périphérie, le fond et lesdites parois latérales formant un volume interne de stockage, lesdites parois latérales étant composées de deux premières parois opposées, et de deux deuxièmes parois opposées, chacune desdites deux deuxièmes parois présentant deux rabats fixés sur une face de ladite première paroi adjacente respective, de sorte à former quatre renforts d'angle, ladite caisse selon l'invention étant caractérisée en ce que, pour chacun desdits quatre renforts d'angle, l'un dudit rabat ou de ladite première paroi présente une première arête d'extrémité portant au moins un tenon, et une deuxième arête d'extrémité opposée à ladite première arête d'extrémité portant au moins une mortaise placée au droit dudit tenon, l'autre dudit rabat ou de ladite première paroi formant la face interne dudit renfort d'angle de sorte à occulter ladite mortaise depuis l'intérieur dudit volume interne de stockage, chacune des arêtes d'extrémité des premières parois ou des rabats présentant au moins une encoche formée dans la continuité de chacun des tenons, de forme complémentaire à la forme du tenon adjacent.The invention meets this need by providing a box for transport, in particular for the transport of goods, said box comprising a rectangular bottom, from which side walls extend on the periphery, the bottom and said side walls forming a internal storage volume, said side walls being composed of two opposite first walls, and of two opposite second walls, each of said two second walls having two flaps fixed on one face of said respective adjacent first wall, so as to form four reinforcements of ' angle, said box according to the invention being characterized in that, for each of said four corner reinforcements, one of said flap or of said first wall has a first end edge carrying at least one tenon, and a second edge end opposite to said first end edge carrying at least one mortise placed in line with said tenon, the other of said flap or of said first wall forming the internal face of said corner reinforcement so as to conceal said mortise from inside said internal storage volume, each of the end ridges of the first walls or of the flaps having at least one notch formed in the continuity of each of the tenons , of complementary shape to the shape of the adjacent tenon.

Ainsi, l'invention repose sur une approche nouvelle et inventive pour le transport de marchandises qui permette de limiter les risques de fuite de marchandises ainsi que les risques de contamination de cette marchandise contenue à l'intérieur d'une caisse donnée. En effet, le fait que lesdites mortaises depuis l'intérieur dudit volume interne de stockage, et donc que le fond ne présente pas de trou, limite les risques de fuite de marchandises ainsi que les risques de contamination de cette marchandise contenue à l'intérieur.Thus, the invention is based on a new and inventive approach to the transport of goods which makes it possible to limit the risks of goods leaking as well as the risks of contamination of this goods contained within a given crate. Indeed, the fact that said mortises from inside said internal storage volume, and therefore that the bottom does not have a hole, limits the risks of goods leaking as well as the risks of contamination of this goods contained inside. .

En outre, la présence de tenons et de mortaises permet de former une pile relativement stable, afin d'optimiser le transport, voire de permettre l'automatisation de la formation des piles de caisses.In addition, the presence of tenons and mortises makes it possible to form a relatively stable stack, in order to optimize the transport, or even to allow the automation of the formation of the stacks of boxes.

De plus, l'encoche réalisée qui est de forme complémentaire à la forme du tenon adjacent permet de faire des économies de matière lors de la découpe des flans pour former les caisses. En effet, lors de la découpe des flans, cela permet de réaliser deux flans de carton sans perdre trop de matière voire pas de matière.In addition, the notch produced which is of a shape complementary to the shape of the adjacent tenon makes it possible to save material when cutting the blanks to form the boxes. In fact, when cutting the blanks, this makes it possible to produce two cardboard blanks without losing too much material or even no material.

Selon un mode de réalisation particulier de l'invention, ledit fond est rectangulaire de centre P, lesdites deux premières parois opposées étant symétriques par rapport audit centre P dudit fond, et lesdites deux deuxièmes parois opposées étant symétriques par rapport audit centre P dudit fond, chacune desdites deux premières parois présentant ladite première arête d'extrémité portant au moins deux desdits tenons, et ladite deuxième arête d'extrémité, correspondant à une arête de contact avec ledit fond, présentant au moins deux desdites mortaises placées au droit desdits deux tenons, chacun desdits deux rabats desdites deux deuxièmes parois étant fixés sur une face intérieure de ladite première paroi adjacente respective, de sorte à former lesdits quatre renforts d'angle, lesdits rabats formant la face interne desdits renforts d'angle respectifs de sorte à occulter lesdites mortaises depuis l'intérieur dudit volume interne de stockage.According to a particular embodiment of the invention, said bottom is rectangular with center P, said two first opposite walls being symmetrical with respect to said center P of said bottom, and said two second opposite walls being symmetrical with respect to said center P of said bottom, each of said two first walls having said first end edge carrying at least two of said tenons, and said second end edge, corresponding to a contact edge with said bottom, having at least two of said mortises placed in line with said two tenons, each of said two flaps of said two second walls being fixed to an inner face of said respective adjacent first wall, so as to form said four corner reinforcements, said flaps forming the internal face of said respective corner reinforcements so as to conceal said mortises from inside said internal storage volume.

De telles caractéristiques permettent d'optimiser les coûts de réalisation d'une caisse du fait que la quantité de matière perdue lors des découpes s'avère relativement faible. En outre, l'empilement est facilité par la symétrie du fait qu'il est possible d'empiler les caisses selon plusieurs sens, sans toutefois altérer la coopération entre un tenon et une mortaise associée.Such characteristics make it possible to optimize the costs of producing a box owing to the fact that the quantity of material lost during the cutting turns out to be relatively small. In addition, the stacking is facilitated by the symmetry of the fact that it is possible to stack the boxes in several directions, without however altering the cooperation between a tenon and an associated mortise.

Selon une caractéristique particulière d'au moins un mode de réalisation, chacun desdits tenons présente une forme complémentaire à ladite mortaise placée au droit.According to a particular characteristic of at least one embodiment, each of said tenons has a shape complementary to said mortise placed at right angles.

Selon un aspect particulier d'au moins un mode de réalisation de l'invention, lesdites mortaises présentent une dimension supérieure auxdits tenons en regard.According to a particular aspect of at least one embodiment of the invention, said mortises have a dimension greater than said facing tenons.

Ceci est fait de sorte à laisser un jeu entre une mortaise et un tenon d'une caisse placée en dessous au sein d'une pile de caisses. Ainsi, l'empilement de caisses est facilité.This is done so as to leave a gap between a mortise and a tenon of a crate placed below within a stack of crates. Thus, the stacking of boxes is facilitated.

Selon au moins un mode de réalisation de l'invention, les tenons présentent une forme appartenant au groupe comprenant :

  • une forme trapézoïdale ;
  • une forme courbe ;
  • une forme rectangulaire ;
  • une forme triangulaire.

Selon un aspect particulier d'au moins un mode de réalisation, ladite caisse est faite en carton ondulé, et pour chacune desdites deux premières parois, les cannelures de chacun desdits au moins deux tenons s'étendent parallèlement à un axe reliant lesdits deux tenons.According to a particular aspect of at least one embodiment, said box is made of corrugated cardboard, and for each of said two first walls, the grooves of each of said at least two tenons extend parallel to an axis connecting said two tenons.

De ce fait, les tenons présentent une résistance relativement faible et peuvent s'écraser, par appui par exemple d'un couvercle placé de sorte à fermer la caisse, de sorte que la hauteur des piles de caisse pourvues d'un couvercle n'augmente pas par la faute des tenons.As a result, the tenons have a relatively low resistance and can be crushed, for example by pressing a cover placed so as to close the box, so that the height of the box stacks provided with a lid does not increase. not the fault of the studs.

Selon un aspect particulier d'au moins un autre mode de réalisation, ladite caisse est faite en carton ondulé, et pour chacune desdites deux premières parois, les cannelures de chacun desdits au moins deux tenons s'étendent orthogonalement à un axe reliant lesdits deux tenons.According to a particular aspect of at least one other embodiment, said box is made of corrugated cardboard, and for each of said two first walls, the grooves of each of said at least two tenons extend orthogonally to an axis connecting said two tenons. .

De ce fait, les tenons présentent une résistance relativement haute et l'empilement est résistant.As a result, the posts have a relatively high strength and the stack is resistant.

Selon un autre mode de réalisation de l'invention, la caisse comprend un fond rectangulaire, à partir duquel s'étendent des parois latérales sur la périphérie, le fond et les parois latérales formant un volume interne de stockage, les parois latérales étant composées de deux premières parois opposées, et de deux deuxièmes parois opposées, chacune des deux deuxièmes parois présentant deux rabats fixés sur une face de la première paroi adjacente respective, de sorte à former quatre renforts d'angle.

Description détaillée de plusieurs modes de réalisation de l'inventionDetailed description of several embodiments of the invention

Le principe général de l'invention repose sur la mise en œuvre d'une caisse en carton pour le transport, notamment pour le transport de marchandises telles que des marchandises périssables, ou de produits, qui permette de limiter les risques de fuite de marchandises ainsi que les risques de contamination de cette marchandise contenue à l'intérieur d'une caisse donnée.The general principle of the invention is based on the implementation of a cardboard box for transport, in particular for the transport of goods such as perishable goods, or products, which makes it possible to limit the risks of goods leaking as well. that the risks of contamination of this merchandise contained inside a given case.

Il repose également sur la mise en œuvre de caisses pour le transport qui permette de former une pile relativement stable des caisses vides pour les acheminer vers le lieu d'utilisation, afin d'optimiser le transport, voire de permettre l'automatisation de la formation des piles de caisses.It is also based on the implementation of boxes for transport which makes it possible to form a relatively stable stack of empty boxes to transport them to the place of use, in order to optimize the transport, even to allow the automation of the training. stacks of crates.

Selon ce principe général, l'invention met en œuvre une caisse pour le transport, notamment pour le transport de marchandises, cette caisse comprenant un fond rectangulaire, à partir duquel s'étendent des parois latérales sur la périphérie, le fond et les parois latérales formant un volume interne de stockage.According to this general principle, the invention uses a box for transport, in particular for the transport of goods, this box comprising a rectangular bottom, from which side walls extend on the periphery, the bottom and the side walls. forming an internal storage volume.

Ces parois latérales sont composées de deux premières parois opposées, et de deux deuxièmes parois opposées.These side walls are composed of two opposing first walls, and two opposing second walls.

Chacune des deux deuxièmes parois présente deux rabats fixés sur une face de la première paroi adjacente respective, de sorte à former quatre renforts d'angle.Each of the two second walls has two flaps fixed to one face of the respective adjacent first wall, so as to form four corner reinforcements.

Selon l'invention, pour chacun desdits quatre renforts d'angle, l'un du rabat ou de la première paroi présente une première arête d'extrémité portant au moins un tenon, et une deuxième arête d'extrémité opposée à la première arête d'extrémité portant au moins une mortaise placée au droit du tenon. Quant à l'autre du rabat ou de la première paroi, il forme la face interne du renfort d'angle de sorte à occulter la mortaise depuis l'intérieur du volume interne de stockage.According to the invention, for each of said four corner reinforcements, one of the flap or of the first wall has a first end edge carrying at least one tenon, and a second end edge opposite the first end edge carrying at least one mortise placed in line with the tenon. As for the other of the flap or of the first wall, it forms the internal face of the corner reinforcement so as to conceal the mortise from inside the internal storage volume.

En d'autres termes, la caisse selon l'invention ne présente pas de trous dans le fond, lorsqu'elle est formée.In other words, the box according to the invention does not have holes in the bottom, when it is formed.

Les mortaises étant formées à l'endroit du renfort d'angle sur la face externe de ce renfort d'angle, c'est-à-dire sur la partie externe de la double épaisseur formée par le renfort d'angle, la partie interne de la double épaisseur du renfort d'angle vient occulter l'ouverture faite par la mortaise au niveau du fond de sorte que la caisse ne présente pas de trou dans le fond, lorsqu'elle est formée.The mortises being formed at the location of the corner reinforcement on the external face of this corner reinforcement, that is to say on the external part of the double thickness formed by the corner reinforcement, the internal part the double thickness of the corner reinforcement obscures the opening made by the mortise at the bottom so that the body does not have a hole in the bottom, when it is formed.

On présente maintenant, en relation avec les figures 1 à 8, un mode de réalisation particulier de l'invention.We now present, in relation to the figures 1 to 8 , a particular embodiment of the invention.

Comme illustré sur ces figures, l'invention concerne tout d'abord une caisse 1 pour le transport. De telles marchandises peuvent être périssables et peuvent par exemple comprendre des lots de viande, des fruits ou des légumes. Cela peut également être des marchandises non périssables tel que des récipients thermoformés, des emballages en carton alimentaire, ou des flacons.As illustrated in these figures, the invention relates first of all to a box 1 for transport. Such goods can be perishable and can for example include batches of meat, fruits or vegetables. It can also be non-perishable goods such as thermoformed containers, food carton packaging, or vials.

Dans ce mode de réalisation illustré, la caisse 1 comprend un fond 2 rectangulaire de centre P, duquel s'étendent des parois latérales 3, 4 sur la périphérie du fond 2. Ce fond 2 et ces parois latérales 3, 4 forment ainsi un volume interne de stockage.In this illustrated embodiment, the box 1 comprises a rectangular bottom 2 of center P, from which side walls 3, 4 extend on the periphery of the bottom 2. This bottom 2 and these side walls 3, 4 thus form a volume internal storage.

Il est à noter que le fond rectangulaire pourrait, selon un mode de réalisation particulier, être de forme carrée.It should be noted that the rectangular bottom could, according to a particular embodiment, be of square shape.

La périphérie de parois latérales 3, 4 est composé de deux premières parois 3 opposées, symétriques par rapport au centre P du fond 2 correspondant, et de deux deuxièmes parois 4 opposées, symétriques par rapport au centre P du fond 2.The periphery of side walls 3, 4 is composed of two first opposite walls 3, symmetrical with respect to the center P of the corresponding bottom 2, and of two second opposite walls 4, symmetrical with respect to the center P of the bottom 2.

En d'autres termes, les parois latérales formant la périphérie de la caisse 1 sont symétriques deux à deux par rapport au centre P du fond 2, les parois latérales étant opposées l'une à l'autre. Ainsi, chaque première paroi 3 est adjacente à deux deuxièmes parois 4, chacune des deux deuxièmes parois 4 étant de part et d'autre de cette première paroi 3. Similairement, chaque deuxième paroi 4 est adjacente à deux premières parois 3, chacune des deux premières parois 3 étant de part et d'autre de cette deuxième paroi 4.In other words, the side walls forming the periphery of the body 1 are symmetrical two by two with respect to the center P of the bottom 2, the side walls being opposite to each other. Thus, each first wall 3 is adjacent to two second walls 4, each of the two second walls 4 being on either side of this first wall 3. Similarly, each second wall 4 is adjacent to two first walls 3, each of the two first walls 3 being on either side of this second wall 4.

La caisse 1 présente donc une symétrie centrale de centre P. Une telle symétrie présente notamment des avantages pour la réalisation du flan de carton.The box 1 therefore has a central symmetry of center P. Such symmetry has in particular advantages for the production of the cardboard blank.

Il est à noter que, selon une variante, on pourrait mettre en œuvre une caisse qui présente une symétrie axiale, par exemple d'axe transversal passant par le centre du fond de la caisse.It should be noted that, according to a variant, one could implement a body which has axial symmetry, for example with a transverse axis passing through the center of the bottom of the body.

Comme illustré notamment en figure 1, chacune des deux deuxièmes parois présente deux rabats 40 fixés sur une face de la première paroi adjacente respective, de sorte à former quatre renforts d'angle 5.As illustrated in particular in figure 1 , each of the two second walls has two flaps 40 fixed to one face of the respective first adjacent wall, so as to form four corner reinforcements 5.

Selon l'invention, pour chacun des quatre renforts d'angle 5, l'un du rabat 40 ou de la première paroi 3 présente une première arête d'extrémité portant au moins un tenon 30, et une deuxième arête d'extrémité opposée à la première arête d'extrémité portant au moins une mortaise 32 placée au droit du tenon.According to the invention, for each of the four corner reinforcements 5, one of the flap 40 or of the first wall 3 has a first end edge carrying at least one tenon 30, and a second end edge opposite to the first end edge carrying at least one mortise 32 placed in line with the tenon.

Ici, c'est chacune des deux premières parois 3 qui présente l'arête d'extrémité portant deux tenons 30 (un par renfort d'angle 5), et l'arête de contact avec le fond 2 présentant deux mortaises 32 (également un par renfort d'angle 5) placées au droit des deux tenons 30.Here, it is each of the two first walls 3 which has the end edge carrying two tenons 30 (one per corner reinforcement 5), and the contact edge with the bottom 2 having two mortises 32 (also a by corner reinforcement 5) placed in line with the two tenons 30.

En d'autres termes, chaque première paroi présente, sur son arête d'extrémité, qui forme une partie du bord supérieur de la caisse, deux tenons 30. Ces deux tenons 30 sont ménagés en vis-à-vis de deux mortaises 32 formées à l'endroit de l'arête de contact avec le fond 2, qui forme dans ce mode de réalisation une partie du bord inférieur de la caisse.In other words, each first wall has, on its end edge, which forms part of the upper edge of the body, two tenons 30. These two tenons 30 are arranged opposite two mortises 32 formed. at the location of the edge of contact with the bottom 2, which in this embodiment forms part of the lower edge of the body.

Les mortaises étant formées à l'endroit de l'arête de contact entre la première paroi 3 et le fond 2, elles sont également en partie portées par la paroi de fond 2.The mortises being formed at the location of the contact edge between the first wall 3 and the bottom 2, they are also partly carried by the bottom wall 2.

Les tenons sont placés en vis-à-vis des mortaises pour que, lors d'un empilement de caisses selon l'invention, la pile de caisses puisse être stable et que les tenons d'une caisse placée en dessous puissent venir s'insérer dans les mortaises d'une caisse placée au-dessus.The tenons are placed opposite the mortises so that, during a stacking of boxes according to the invention, the stack of boxes can be stable and that the tenons of a box placed below can be inserted. in the mortises of a box placed above.

Dans ce mode de réalisation, chacun des tenons 30 présente une forme complémentaire à la mortaise 32 placée au droit, ou en regard, de sorte à pouvoir coopérer avec une caisse placée en dessous au sein d'une pile de caisse.In this embodiment, each of the tenons 30 has a shape complementary to the mortise 32 placed to the right, or opposite, so as to be able to cooperate with a box placed below within a stack of boxes.

On illustre en figure 5 une pile de caisses selon un mode de réalisation de l'invention. Comme illustré, pour un nombre N de caisses, avec N=2 dans l'exemple illustré, les tenons d'une caisse N-1 sont insérés dans les mortaises de la caisse N.We illustrate in figure 5 a stack of boxes according to one embodiment of the invention. As illustrated, for a number N of boxes, with N = 2 in the example illustrated, the tenons of an N-1 box are inserted into the mortises of the N box.

Le fait que les caisses soient symétriques par rapport au centre du fond de la caisse permet que l'empilement des caisses soit relativement simple. En effet, il n'y a pas de sens particulier à respecter pour empiler une caisse N+1 sur une caisse N, mise à part la mise en regard des tenons de la caisse N avec les mortaises de la caisse N+1.The fact that the boxes are symmetrical with respect to the center of the bottom of the box allows the stacking of boxes to be relatively simple. In fact, there is no particular meaning to be observed in order to stack an N + 1 box on a N box, apart from placing the tenons of the N box opposite the mortises of the N + 1 box.

Selon une variante de l'invention, les mortaises 32 présentent une dimension supérieure aux tenons 30 en regard. De cette manière, cela permet de laisser un jeu entre une mortaise et un tenon d'une caisse placée en dessous au sein d'une pile de caisses. Cela permet de faciliter l'empilement des caisses en permettant un empilement stable et relativement résistant.According to a variant of the invention, the mortises 32 have a larger dimension than the facing tenons 30. In this way, it allows to leave a clearance between a mortise and a tenon of a box placed below within a stack of boxes. This makes it possible to facilitate the stacking of boxes by allowing a stable and relatively resistant stacking.

Dans ce mode de réalisation, et comme plus particulièrement visibles aux figures 1 et 2, les quatre tenons 30 présentent tous une forme trapézoïdale. Toutefois, selon d'autres variantes, les tenons pourraient également présenter une forme appartenant au groupe comprenant :

  • une forme trapézoïdale ;
  • une forme arrondie ;
  • une forme triangulaire,
  • une forme rectangulaire, par exemple carrée.
In this embodiment, and as more particularly visible to figures 1 and 2 , the four tenons 30 all have a trapezoidal shape. However, according to other variants, the tenons could also have a shape belonging to the group comprising:
  • a trapezoidal shape;
  • a rounded shape;
  • a triangular shape,
  • a rectangular shape, for example square.

En outre, les tenons pourraient également présenter une forme différente. Par exemple, on pourrait mettre en œuvre une caisse présentant deux tenons trapézoïdaux et deux tenons arrondis, à partir du moment où la symétrie centrale de la caisse est réalisée, pour des raisons de fabrication des flans de cartons limitant la perte de matière lors de la découpe.In addition, the tenons could also have a different shape. For example, one could implement a box having two trapezoidal tenons and two rounded tenons, from the moment when the central symmetry of the body is achieved, for manufacturing reasons of the cardboard blanks limiting the loss of material during the packing. cutting.

On pourrait également prévoir un mode de réalisation dans lequel il y aurait un nombre supérieur à 2 de tenons par première paroi, ce nombre de tenons étant un multiple de deux du fait de la symétrie centrale.An embodiment could also be provided in which there would be a number greater than 2 of tenons per first wall, this number of tenons being a multiple of two due to the central symmetry.

On pourrait également prévoir des parois non symétriques avec des tenons en nombres et formes différentes, placés au niveau des renforts d'angle.One could also provide non-symmetrical walls with tenons of different numbers and shapes, placed at the level of the corner reinforcements.

De leur côté, chacune des deux deuxièmes parois 4 présente deux arêtes latérales comprenant chacune un rabat 40 intérieur fixé sur une face intérieure de la première paroi 3 adjacente respective.For their part, each of the two second walls 4 has two lateral ridges each comprising an interior flap 40 fixed on an interior face of the respective first adjacent wall 3.

Ces rabat 40 forment un renfort d'angle et permettent de maintenir fixe chacune des deuxièmes parois 4 aux premières parois 3 adjacentes. De cette manière, la paroi périphérique de la caisse est sensiblement continue.These flaps 40 form a corner reinforcement and make it possible to keep each of the second walls 4 fixed to the first adjacent walls 3. In this way, the peripheral wall of the body is substantially continuous.

Selon l'invention, ces rabats 40 intérieurs recouvrent la portion d'arête portant les mortaises 32 de sorte à occulter les mortaises 32 depuis l'intérieur du volume interne de stockage.According to the invention, these interior flaps 40 cover the ridge portion carrying the mortises 32 so as to conceal the mortises 32 from inside the internal storage volume.

En d'autres termes, la caisse 1 selon l'invention ne présente pas de trous dans le fond 2, lorsqu'elle est formée.In other words, the body 1 according to the invention does not have holes in the bottom 2, when it is formed.

Les mortaises étant formées à l'endroit de l'arête de contact entre la première paroi 3 et le fond 2 (voir figure 4) et étant donc également en partie portées par la paroi de fond 2, l'épaisseur de chacun des rabat 40 vient occulter l'ouverture faite par la mortaise 32 au niveau du fond 2 de sorte que la caisse 1 ne présente pas de trou dans le fond 2, lorsqu'elle est formée.The mortises being formed at the location of the contact edge between the first wall 3 and the bottom 2 (see figure 4 ) and therefore also being partly carried by the bottom wall 2, the thickness of each of the flaps 40 obscures the opening made by the mortise 32 at the level of the bottom 2 so that the body 1 does not have a hole in it. the bottom 2, when it is formed.

Les rabats 40 forment ainsi une double épaisseur pour la paroi périphérique de la caisse, cette double épaisseur étant formée par la superposition d'une première paroi donnée et des deux rabats qui sont collés sur la face intérieure de cette première paroi. La caisse 1 illustrée dans le mode de réalisation présente ainsi quatre zones de double épaisseur.The flaps 40 thus form a double thickness for the peripheral wall of the body, this double thickness being formed by the superposition of a first given wall and the two flaps which are glued to the inner face of this first wall. The box 1 illustrated in the embodiment thus has four zones of double thickness.

De ce fait, les tenons et les mortaises de la caisse se retrouvent sur une partie externe de la double épaisseur formée par la première paroi 3 et chacun des rabats 40, les rabats 40 formant la partie interne.As a result, the tenons and the mortises of the body are found on an external part of the double thickness formed by the first wall 3 and each of the flaps 40, the flaps 40 forming the internal part.

Ainsi, une telle caisse 1 permet de limiter les risques de fuite de marchandises ainsi que les risques de contamination de la marchandise contenue à l'intérieur de cette caisse 1. En effet, du fait qu'il n'y ait pas d'ouverture dans le fond pour que la marchandise puisse entrer en contact avec l'extérieur, les risques de contamination se retrouvent fortement limités.Thus, such a box 1 makes it possible to limit the risks of goods leaking as well as the risks of contamination of the goods contained inside this box 1. Indeed, due to the fact that there is no opening at the bottom so that the goods can come into contact with the outside, the risks of contamination are greatly limited.

Il est à noter que la caisse présentée dans ce mode de réalisation comprend quatre rabats. On pourrait toutefois prévoir une caisse présentant un nombre différent de rabats.It should be noted that the box presented in this embodiment comprises four flaps. It would however be possible to provide a box having a different number of flaps.

Ces rabats 40 sont, de manière classique, fixés sur l'intérieur des premières parois 3 par le biais d'une colle injectée sous pression, à séchage ultra rapide.These flaps 40 are conventionally fixed to the inside of the first walls 3 by means of an adhesive injected under pressure, ultra-fast drying.

Comme visible sur les figures 1 et 2, dans ce mode de réalisation, les rabats 40 viennent en juxtaposition des tenons 30. Toutefois, ces tenons 30 émergent au-dessus des rabats. En d'autres termes, la hauteur des premières parois à l'endroit des tenons est plus grande que la hauteur des rabats, qui ne dépassent pas, dans ce mode de réalisation, la hauteur de la première paroi.As visible on the figures 1 and 2 , in this embodiment, the flaps 40 come in juxtaposition of the tenons 30. However, these tenons 30 emerge above the flaps. In other words, the height of the first walls at the location of the tenons is greater than the height of the flaps, which do not, in this embodiment, exceed the height of the first wall.

Dans le mode de réalisation illustré, les premières parois s'avèrent être les largeurs de la caisse tandis que les deuxièmes parois s'avèrent être les longueurs de la caisse. Toutefois, selon une variante, on pourrait mettre en œuvre une caisse dans laquelle les premières parois seraient les longueurs de la caisse tandis que les deuxièmes parois seraient les largeurs de la caisse, sans pour autant sortir du cadre de l'invention.In the illustrated embodiment, the first walls turn out to be the widths of the box while the second walls turn out to be the lengths of the box. However, according to a variant, one could implement a box in which the first walls would be the lengths of the box while the second walls would be the widths of the box, without departing from the scope of the invention.

Selon un mode de réalisation de l'invention, la caisse peut également être munie d'un couvercle. Ce couvercle peut correspondre à une caisse identique à la caisse mise en œuvre dans l'invention, mais présentant des dimensions légèrement plus grandes de sorte à pouvoir englober les parois de périphérie de la caisse 1.According to one embodiment of the invention, the box can also be provided with a cover. This cover may correspond to a box identical to the box implemented in the invention, but having slightly larger dimensions so as to be able to include the peripheral walls of the box 1.

De sorte à ce que la hauteur de la caisse munie d'un couvercle ne présente pas un encombrement trop important, les cannelures de chacun des tenons 30 de la caisse sont ménagées sensiblement parallèlement à une direction D reliant les tenon 30 d'une même première paroi.So that the height of the box provided with a cover does not take up too much space, the grooves of each of the tenons 30 of the body are formed substantially parallel to a direction D connecting the tenons 30 of the same first wall.

En d'autres termes, les cannelures sont ménagées selon une direction sensiblement transversale de la caisse du mode de réalisation illustré.In other words, the grooves are formed in a substantially transverse direction of the body of the illustrated embodiment.

De ce fait, lorsque le couvercle est posé, les tenons de la caisse peuvent venir s'écraser et la hauteur représentée par la hauteur des tenons de la caisse n'augmente pas, ou très peu, la hauteur de l'ensemble représenté par la caisse et le couvercle.As a result, when the cover is fitted, the tenons of the body may come crashing down and the height represented by the height of the tenons of the body does not increase, or very little, the height of the assembly represented by the crate and cover.

Quant aux cannelures de chacun des tenons du couvercle ils s'étendent orthogonalement à un axe reliant lesdits deux tenons.As for the grooves of each of the tenons of the cover, they extend orthogonally to an axis connecting said two tenons.

De ce fait, les tenons présentent une résistance relativement haute et l'empilement est résistant.As a result, the posts have a relatively high strength and the stack is resistant.

De ce fait, lorsque le couvercle est posé, pendant que les tenons de la caisse peuvent venir s'écraser, ceux du couvercle assurent le maintien en pile.Therefore, when the cover is placed, while the tenons of the body can come crashing, those of the cover ensure the maintenance in the stack.

Comme visible plus particulièrement sur la figure 3, chacune des arêtes d'extrémité des deux premières parois 3 présente au moins une encoche 31 formée dans la continuité de chacun des tenons 30, de forme complémentaire à la forme du tenon 30 adjacent.As visible more particularly on the figure 3 , each of the end ridges of the two first walls 3 has at least one notch 31 formed in the continuity of each of the tenons 30, of a shape complementary to the shape of the adjacent tenon 30.

En d'autres termes, dans la continuité de chacun des tenons 30, les premières parois 3 présentent des encoches 31 dont la forme est le négatif du tenon adjacent.In other words, in the continuity of each of the tenons 30, the first walls 3 have notches 31 whose shape is the negative of the adjacent tenon.

En d'autres termes encore, la forme des encoches 31 est un négatif de la forme du tenon adjacent, par symétrie centrale de centre C' correspondant au point de la base du tenon à partir duquel s'étend l'encoche.In other words still, the shape of the notches 31 is a negative of the shape of the adjacent post, by central symmetry of center C 'corresponding to the point of the base of the post from which the notch extends.

Chacune de ces encoches 31 correspond à la découpe d'un tenon d'un flan d'une autre caisse. Ceci est plus particulièrement visible aux figures 6 et 7.Each of these notches 31 corresponds to the cutting of a tenon from a blank of another box. This is more particularly visible to figures 6 and 7 .

En effet, lors de la découpe de flan de carton dans des plaques ou rouleau de matière en carton, et de sorte à réduire les pertes de matière, les découpes de deux flans sont imbriquées de sorte que les tenons d'une première paroi latérale d'un flan correspondent aux encoches d'une première paroi latérale d'un flan adjacent.Indeed, during the cutting of cardboard blanks in plates or rolls of cardboard material, and so as to reduce material losses, the cutouts of two blanks are nested so that the tenons of a first side wall d 'a blank correspond to the notches of a first side wall of an adjacent blank.

Comme illustré chaque flan en carton destiné à former une caisse 1 pour le transport comprend un fond 2 rectangulaire de centre P, duquel s'étendent des parois latérales 3, 4 sur la périphérie, le fond 2 et les parois latérales 3, 4 formant un volume interne de stockage, les parois latérales 3, 4 étant composées de deux premières parois 3 opposées, symétriques par rapport au centre P du fond 2 correspondant, et de deux deuxièmes parois 4 opposées, symétriques par rapport au centre P du fond 2. Chacune des deux premières parois 3 présente une arête d'extrémité portant au moins deux tenons 30, et au moins une arête de contact avec le fond 2 présentant deux mortaises 32 placées au droit des deux tenons 30. En outre, chacune des deux deuxièmes parois 4 présente deux arêtes latérales comprenant chacune un rabat 40 configuré pour venir se fixer sur une face intérieure de la première paroi 3 adjacente respective, les rabats 40 intérieurs étant configurés pour recouvrir la portion d'arête portant les mortaises 32 de sorte à occulter les mortaises 32 depuis l'intérieur du volume interne de stockage.As illustrated, each cardboard blank intended to form a box 1 for transport comprises a rectangular bottom 2 of center P, from which side walls 3, 4 extend on the periphery, the bottom 2 and the side walls 3, 4 forming a internal storage volume, the side walls 3, 4 being composed of two first opposing walls 3, symmetrical with respect to the center P of the corresponding bottom 2, and of two second opposite walls 4, symmetrical with respect to the center P of the bottom 2. Each of the two first walls 3 has an end edge carrying at least two tenons 30, and at least one edge of contact with the bottom 2 having two mortises 32 placed in line with the two tenons 30. In addition, each of the two second walls 4 has two lateral ridges each comprising a flap 40 configured to come to be fixed on an inner face of the respective adjacent first wall 3, the inner flaps 40 being configured to cover the port ridge portion ant the mortises 32 so as to conceal the mortises 32 from inside the internal storage volume.

Plus généralement, selon l'invention, le flan en carton destiné à former une caisse pour le transport comprend un fond rectangulaire, à partir duquel s'étendent des parois latérales sur la périphérie, le fond et les parois latérales étant aptes à former un volume interne de stockage, lesdites parois latérales étant composées de deux premières parois opposées, et de deux deuxièmes parois opposées, chacune des deux deuxièmes parois présentant deux rabats fixés sur une face de la première paroi adjacente respective, de sorte à former quatre renforts d'angle. Pour chacun des quatre renforts d'angle l'un du rabat ou de la première paroi présente une première arête d'extrémité portant au moins un tenon, et une deuxième arête d'extrémité opposée à la première arête d'extrémité portant au moins une mortaise placée au droit du tenon, l'autre du rabat ou de la première paroi étant configuré pour former la face interne du renfort d'angle de sorte à occulter les mortaises depuis l'intérieur du volume interne de stockage.More generally, according to the invention, the cardboard blank intended to form a box for transport comprises a rectangular bottom, from which side walls extend on the periphery, the bottom and the side walls being able to form a volume. internal storage, said side walls being composed of two opposite first walls, and two opposite second walls, each of the two second walls having two flaps fixed on one face of the respective first adjacent wall, so as to form four corner reinforcements. For each of the four corner reinforcements, one of the flap or of the first wall has a first end edge carrying at least one tenon, and a second end edge opposite the first end edge carrying at least one. mortise placed in line with the tenon, the other of the flap or of the first wall being configured to form the internal face of the corner reinforcement so as to conceal the mortises from inside the internal storage volume.

Avant de détailler le procédé pour la réalisation d'une caisse pour le transport, on détaille ci-après deux autres modes de réalisation de la caisse.Before detailing the process for producing a box for transport, two other embodiments of the box are described in detail below.

La figure 9 illustre un deuxième mode de réalisation d'une caisse pour le transport. Selon ce mode de réalisation, les rabats sont collés sur la face extérieure des premières parois et portent les mortaises 32' et les tenons 30'.The figure 9 illustrates a second embodiment of a transport case. According to this embodiment, the flaps are glued to the outer face of the first walls and carry the mortises 32 'and the tenons 30'.

Ainsi, la caisse 1' comprend un fond 2' rectangulaire, à partir duquel s'étendent des parois latérales 3', 4' sur la périphérie, le fond 2' et les parois latérales 3', 4' formant un volume interne de stockage, les parois latérales 3', 4' étant composées de deux premières parois 3' opposées, et de deux deuxièmes parois 4' opposées, chacune des deux deuxièmes parois 4' présentant deux rabats 40' fixés sur une face de la première paroi 3' adjacente respective, de sorte à former quatre renforts d'angle 5'.Thus, the box 1 'comprises a rectangular bottom 2', from which extend side walls 3 ', 4' on the periphery, the bottom 2 'and the side walls 3', 4 'forming an internal storage volume. , the side walls 3 ', 4' being composed of two opposite first walls 3 ', and of two opposite second walls 4', each of the two second walls 4 'having two flaps 40' fixed on one face of the first wall 3 ' respective adjacent, so as to form four corner reinforcements 5 '.

Pour chacun des quatre renforts d'angle 5' le rabat 40' présente une première arête d'extrémité portant au moins un tenon 30', et une deuxième arête d'extrémité opposée à la première arête d'extrémité portant au moins une mortaise 32' placée au droit du tenon 30', la première paroi 3' formant la face interne du renfort d'angle 5' de sorte à occulter la mortaise 32' depuis l'intérieur du volume interne de stockage.For each of the four corner reinforcements 5 ', the flap 40' has a first end edge carrying at least one tenon 30 ', and a second end edge opposite the first end edge carrying at least one mortise 32 'placed to the right of the tenon 30', the first wall 3 'forming the internal face of the corner reinforcement 5' so as to conceal the mortise 32 'from inside the internal storage volume.

La figure 10 illustre un troisième mode de réalisation d'une caisse pour le transport. Selon ce mode de réalisation, les rabats sont collés sur la face extérieure des premières parois et portent les mortaises 32" et les tenons 30". Ceux-ci sont toutefois inversés par rapport au deuxième mode de réalisation, les tenons étant en bas et les mortaises en haut de la caisse 1", selon un sens normal d'utilisation de la caisse 1".The figure 10 illustrates a third embodiment of a transport case. According to this embodiment, the flaps are glued to the outer face of the first walls and carry the mortises 32 "and the tenons 30". These are however reversed with respect to the second embodiment, the tenons being at the bottom and the mortises at the top of the body 1 ", in a normal direction of use of the body 1".

Ainsi, la caisse 1" comprend un fond 2" rectangulaire, à partir duquel s'étendent des parois latérales 3", 4" sur la périphérie, le fond 2" et les parois latérales 3", 4" formant un volume interne de stockage, les parois latérales 3", 4" étant composées de deux premières parois 3" opposées, et de deux deuxièmes parois 4" opposées, chacune des deux deuxièmes parois 4" présentant deux rabats 40" fixés sur une face de la première paroi 3" adjacente respective, de sorte à former quatre renforts d'angle 5".Thus, the box 1 "comprises a rectangular bottom 2", from which extend side walls 3 ", 4" on the periphery, the bottom 2 "and the side walls 3", 4 "forming an internal storage volume. , the side walls 3 ", 4" being composed of two first opposing walls 3 ", and two second opposing walls 4", each of the two second walls 4 "having two flaps 40" fixed on one face of the first wall 3 " respective adjacent, so as to form four corner reinforcements 5 ".

Pour chacun des quatre renforts d'angle 5" le rabat 40" présente une première arête d'extrémité portant au moins un tenon 30", et une deuxième arête d'extrémité opposée à la première arête d'extrémité portant au moins une mortaise 32" placée au droit du tenon 30", la première paroi 3" formant la face interne du renfort d'angle 5" de sorte à occulter la mortaise 32" depuis l'intérieur du volume interne de stockage.For each of the four corner reinforcements 5 "the flap 40" has a first end edge carrying at least one tenon 30 ", and a second end edge opposite the first end edge carrying at least one mortise 32 "placed in line with the tenon 30", the first wall 3 "forming the internal face of the corner reinforcement 5" so as to conceal the mortise 32 "from inside the volume internal storage.

La figure 11 illustre un quatrième mode de réalisation d'une caisse pour le transport. Selon ce mode de réalisation, les rabats 40'" sont collés sur la face intérieure des premières parois 3"', ces premières parois portant les mortaises 32'" et les tenons 30'". Ceux-ci sont toutefois inversés par rapport au premier mode de réalisation, les tenons 30'" étant en bas et les mortaises 32'" en haut de la caisse 1", selon un sens normal d'utilisation de la caisse 1"'.The figure 11 illustrates a fourth embodiment of a transport case. According to this embodiment, the flaps 40 '"are glued to the inside face of the first walls 3"', these first walls carrying the mortises 32 '"and the tenons 30'". These are however reversed with respect to the first embodiment, the tenons 30 '"being at the bottom and the mortises 32'" at the top of the body 1 ", in a normal direction of use of the body 1"'.

Ainsi, la caisse 1"' comprend un fond 2'" rectangulaire, à partir duquel s'étendent des parois latérales 3"', 4'" sur la périphérie, le fond 2'" et les parois latérales 3"', 4'" formant un volume interne de stockage, les parois latérales 3"', 4'" étant composées de deux premières parois 3'" opposées, et de deux deuxièmes parois 4'" opposées, chacune des deux deuxièmes parois 4'" présentant deux rabats 40'" fixés sur une face intérieure de la première paroi 3'" adjacente respective, de sorte à former quatre renforts d'angle 5"'.Thus, the box 1 "'comprises a rectangular bottom 2'", from which extend side walls 3 "', 4'" on the periphery, the bottom 2 '"and the side walls 3"', 4 '. "forming an internal storage volume, the side walls 3" ', 4' "being composed of two first walls 3 '" opposed, and two second walls 4' "opposite, each of the two second walls 4 '" having two flaps 40 '"fixed to an inner face of the respective first adjacent wall 3'", so as to form four corner reinforcements 5 "'.

On présente maintenant, en relation avec la figure 8, un procédé 100 pour la réalisation d'une caisse pour le transport selon l'invention, à partir d'un flan en carton.We now present, in relation to the figure 8 , a method 100 for producing a transport case according to the invention, from a cardboard blank.

Comme illustré sur cette figure 8, le procédé comprend les étapes suivantes :

  • convoyage 101 du flan à partir d'un magasin de stockage ;
  • pliage 102 du flan en carton de sorte à former la caisse 1 ;
  • évacuation 103 de ladite caisse 1 formée.
As shown on this figure 8 , the method comprises the following steps:
  • conveying 101 of the blank from a storage store;
  • folding 102 of the cardboard blank so as to form the box 1;
  • evacuation 103 of said box 1 formed.

Selon le mode de réalisation illustré, l'étape de pliage 102 comporte :

  • une sous étape 1020 de dépose de colle sur une face de l'un des rabats 40 ou de la première paroi 3 adjacente, apte à venir au contact d'une face de l'autre du rabat 40 ou de la première paroi 3 adjacente ;
  • une sous étape 1021 de fixation des rabats 40 intérieurs au contact des premières parois 3 adjacentes respectives, de sorte à former les renforts d'angle.
According to the illustrated embodiment, the folding step 102 comprises:
  • a sub-step 1020 for depositing glue on one face of one of the flaps 40 or of the first adjacent wall 3, able to come into contact with one face of the other of the flap 40 or of the first adjacent wall 3;
  • a sub-step 1021 for fixing the interior flaps 40 in contact with the respective first adjacent walls 3, so as to form the corner reinforcements.

Selon un mode de réalisation du procédé de fabrication de la caisse 1 illustrée notamment en figure 1, l'étape de pliage comporte ici :

  • une sous étape 1020 de dépose de colle sur la face intérieure de la première paroi 3 adjacente, apte à venir au contact d'une face extérieure des rabats 40 ;
  • une sous étape 1021 de fixation des rabats 40 intérieurs au contact des premières parois 3 adjacentes respectives, de sorte à former les renforts d'angle.
According to an embodiment of the method of manufacturing the body 1 illustrated in particular in figure 1 , the folding step includes here:
  • a sub-step 1020 for depositing glue on the inner face of the first adjacent wall 3, able to come into contact with an outer face of the flaps 40;
  • a sub-step 1021 for fixing the interior flaps 40 in contact with the respective first adjacent walls 3, so as to form the corner reinforcements.

Après l'étape d'évacuation 103 du carton formé, le procédé peut également comprendre une étape 104 de formation d'une pile 9 de N caisses, avec N≥2, par insertion de tenons d'une caisse N-1 dans les mortaises de ladite caisse N.After the step 103 of removing the cardboard formed, the method can also comprise a step 104 of forming a stack 9 of N boxes, with N ≥ 2, by inserting tenons of an N-1 box into the mortises. of said N.

Comme illustré en figure 5, on peut former par exemple une pile de deux caisses 1 par insertion de tenons de la première caisse dans les mortaises de la deuxième caisse (ou d'insertion des mortaises de la deuxième caisse par-dessus les tenons de la première caisse), et procéder de même pour d'autres caisses éventuelles.As shown in figure 5 , for example, a stack of two boxes 1 can be formed by inserting tenons of the first box into the mortises of the second box (or inserting the mortises of the second box over the tenons of the first box), and proceed in the same way for other possible cases.
