Description

Domaine de l'inventionField of the invention

La présente invention se réfère au domaine des boîtes pliables compressibles qui sont par exemple construites avec un carton rigide pliable. En particulier, la présente invention se rapporte au domaine des boîtes en carton pliables compressibles, par exemple les boîtes à pizzas, les boîtes à chaussures ou autres.The present invention relates to the field of compressible collapsible boxes which are for example constructed with a rigid collapsible cardboard. In particular, the present invention relates to the field of compressible foldable cardboard boxes, for example pizza boxes, shoe boxes or the like.

Plus particulièrement, la présente invention porte sur une ébauche d'une boîte pliable compressible, en particulier sur une ébauche d'une boîte à pizza pliable compressible.More particularly, the present invention relates to a blank of a compressible collapsible box, in particular to a blank of a compressible collapsible pizza box.

Etat de la techniqueState of the art

Les boîtes d'emballage sont généralement formées au départ d'une simple feuille de carton (ou d'un autre matériau) configurée pour être pliée le long de lignes de pliage. La majorité de ces boîtes d'emballage sont prévues pour un usage unique et sont fréquemment utilisées pour le stockage temporaire et le transport de marchandises, par exemple pour le stockage temporaire et le transport d'aliments. Une fois que les marchandises sont livrées ou consommées, la boîte doit être jetée ou recyclée par l'utilisateur. Assez souvent, les dimensions de ces boîtes font qu'il est difficile de les jeter ou de les recycler dans des containers à déchets conventionnels, et il serait par conséquent souhaitable que ces boîtes soient préconfigurées pour en assurer une élimination aisée. C'est pourquoi, des boîtes telles que celles décrites dans les documents WO2007/149441 et US2005/087591 comprennent au moins un moyen d'aide à la destruction aidant à la compression/destruction des boîtes pour en réduire la taille et/ou le volume. Il s'agit, dans le document antérieur WO2007/149441 de moyens dits divisionnaires qui facilitent la division de la boîte en au moins deux pièces. Par exemple, ces moyens divisionnaires consistent en des perforations favorisant la déchirure des panneaux formant la boîte. Dans le document US2005/087591 , des lignes de perforations sont prévues pour faciliter un pliage de la boîte en plusieurs parties qui se superposent l'une l'autre de façon à réduire le volume de la boîte.Packaging boxes are typically formed from a single sheet of cardboard (or other material) configured to be folded along fold lines. The majority of these packaging boxes are intended for single use and are frequently used for temporary storage and transport of goods, for example for temporary storage and transport of food. Once the goods are delivered or consumed, the box should be discarded or recycled by the user. Quite often, the dimensions of these boxes make it difficult to dispose of or recycle them in conventional waste containers, and it would therefore be desirable that such boxes be preconfigured to ensure easy disposal. Therefore, boxes such as those described in the documents WO2007 / 149441 and US2005 / 087591 include at least one destruction aid means aiding in the compression / destruction of the boxes to reduce their size and / or volume. It is, in the previous document WO2007 / 149441 so-called divisional means which facilitate the division of the box into at least two parts. For example, these divisional means consist of perforations favoring the tearing of the panels forming the box. In the document US2005 / 087591 , perforation lines are provided to facilitate folding of the box in several parts which overlap one another so as to reduce the volume of the box.

Par ailleurs, des boites munies d'au moins un moyen d'aide à la destruction mais aussi de moyens de maintien de la boîte sous une forme pliée et comprimée sont également connues de l'état de la technique. En ce sens, le document US8919635 décrit une ébauche d'une boîte pliable compressible qui comprend des moyens d'aide à la destruction sous forme de ligne de pliage mais aussi deux prédécoupes qui sont prévues pour se rejoindre et maintenir la boîte sous sa forme pliée et comprimée (compressée). Plus particulièrement, ces deux prédécoupes forment respectivement un premier rabat et un second rabat diamétralement opposés, c'est-à-dire situés chacun dans des angles opposés de l'ébauche de la boîte. Lorsque la boîte est pliée et compressée et que les deux rabats sont déployés au départ de l'ébauche grâce à la présence de lignes perforées permettant de les désolidariser en partie de l'ébauche, les rabats s'étendent vers l'extérieur de la boîte compressée et sont prévus pour s'emboiter l'un dans l'autre en formant une excroissance s'étendant au-delà de la boîte pliée et compressée en accordéon (voir la figure 10 du document US8919635 ).Furthermore, boxes provided with at least one destruction aid means but also with means for maintaining the box in a folded and compressed form are also known from the state of the art. In this sense, the document US8919635 describes a blank for a compressible collapsible box which comprises destruction aid means in the form of a folding line but also two pre-cuts which are provided to meet and hold the box in its folded and compressed (compressed) form. More particularly, these two pre-cuts respectively form a first flap and a second diametrically opposed flap, that is to say each located in opposite angles of the blank of the box. When the box is folded and compressed and the two flaps are deployed at the start of the blank thanks to the presence of perforated lines making it possible to separate them in part from the blank, the flaps extend outwards from the box compressed and are intended to fit into each other forming a protuberance extending beyond the folded and compressed accordion box (see figure 10 of the document US8919635 ).

Le document US2004/0217154 divulgue également une ébauche d'une boîte pliable compressible qui comprend des moyens d'aide à la destruction sous forme de ligne de pliage et des moyens de maintien de la boîte sous sa forme pliée et compressée. Plus particulièrement, l'ébauche est munie, au niveau de deux parois opposées, d'un premier organe mâle sous forme d'une protubérance pourvue d'un organe de connexion pouvant s'étendre au départ d'une paroi et d'un second organe femelle sous forme d'un évidemment pratiqué dans l'autre paroi opposée. Lorsque la boîte est sous sa forme pliée et compressée, un emboitement de l'organe mâle et de son organe de connexion dans l'organe femelle permet d'assurer le maintien de la boîte dans son état plié et compressé.The document US2004 / 0217154 also discloses a blank for a compressible collapsible box which comprises destruction aid means in the form of a fold line and means for maintaining the box in its folded and compressed form. More particularly, the blank is provided, at the level of two opposite walls, with a first male member in the form of a protuberance provided with a connection member which can extend from a wall and a second female organ in the form of a recess made in the other opposite wall. When the box is in its folded and compressed form, an engagement of the male member and its connection member in the female member makes it possible to maintain the box in its folded and compressed state.

Le document NL2018273 divulgue aussi une ébauche d'une boîte pliable compressible qui comprend des moyens d'aide à la destruction sous forme de ligne de pliage et des moyens de maintien de la boîte sous sa forme pliée et compressée. Ces moyens de maintien sont similaires à ceux décrits dans le document US2004/0217154 , à la différence près qu'aucun des moyens de maintien n'est muni d'un organe de connexion.The document NL2018273 also discloses a blank for a compressible collapsible box which comprises destruction aid means in the form of a fold line and means for maintaining the box in its folded and compressed form. These holding means are similar to those described in the document US2004 / 0217154 , with the difference that none of the holding means is provided with a connection member.

Malheureusement, avec des telles ébauches de boîtes telles que décrites dans les documents antérieurs US8919635 , US2004/0217154 et NL2018273 , même si la présence d'au moins un moyen d'aide à la destruction et de moyens de maintien des boîtes sous une forme pliée et compressée permet de réduire le volume des boîtes et de les compacter, il n'en demeure pas moins que les boîtes présentent encore un volume considérable, qu'une certaine distance subsiste entre les parties de boîte pliées (par exemple en accordéon) et que les boîtes regagnent du volume en se décompactant d'elle-même. En effet, les cartons formant les boîtes présentent une certaine rigidité en favorisant une décompaction naturelle suite à leur compression.Unfortunately, with such box blanks as described in earlier documents US8919635 , US2004 / 0217154 and NL2018273 , even if the presence of at least one means of aid in the destruction and of means for maintaining the boxes in a folded and compressed form makes it possible to reduce the volume of the boxes and to compact them, the fact remains that the boxes still have a considerable volume, that a certain distance remains between the folded box parts (for example in accordion) and that the boxes regain volume by unpacking themselves. Indeed, the cartons forming the boxes have a certain rigidity by promoting a natural decompaction following their compression.

En outre, selon ces documents antérieurs, les ébauches comportent toujours deux éléments distincts qui doivent coopérer de telle sorte à assurer un maintien des boîtes sous leur forme pliée et compressée. Ceci implique que la fabrication des ébauches est complexe et coûteuse mais aussi que la procédure permettant d'assurer le maintien des boîtes sous leur forme pliée et compressée est contraignante : il faut toujours qu'un premier élément coopère avec un second, ce qui requière qu'une séquence bien précise d'étapes de manipulation doit être respectée par la personne souhaitant comprimer la boite et en assurer un maintien sous cette forme. Il faut en effet que le pliage de la boîte permette d'avoir accès à chacun des deux éléments, sans quoi une connexion de ces derniers n'est pas possible.In addition, according to these prior documents, the blanks still include two distinct elements which must cooperate in such a way as to ensure that the boxes are held in their folded and compressed form. This implies that the manufacture of the blanks is complex and expensive, but also that the procedure for ensuring the maintenance of the boxes in their folded and compressed form is restrictive: it is always necessary that a first element cooperate with a second, which requires that A very precise sequence of handling steps must be observed by the person wishing to compress the box and ensure that it is held in this form. It is in fact necessary that the folding of the box allows access to each of the two elements, otherwise a connection of the latter is not possible.

En ce qui concerne le document US8919635 , même si la boîte est maintenue sous une forme pliée et compressée, l'excroissance formée par les rabats constituant les moyens de maintien et s'étendant au-delà de la boîte, donne lieu au final à une boîte comprimée qui est malgré tout volumineuse et très peu pratique à stocker ou même à éliminer par exemple dans un sac poubelle (l'excroissance elle-même et ses arêtes constituent autant d'éléments pouvant endommager les sacs poubelles). Par ailleurs, les parties de boîte pliées en accordéon ont tendance à s'écarter l'une de l'autre, ceci étant d'autant plus marqué que ces parties de boîte sont distantes de la zone où se rejoignent les deux rabats.Regarding the document US8919635 , even if the box is maintained in a folded and compressed form, the protuberance formed by the flaps constituting the holding means and extending beyond the box, ultimately gives rise to a compressed box which is nevertheless bulky and very impractical to store or even dispose of, for example in a garbage bag (the growth itself and its edges are all elements that can damage the garbage bags). Furthermore, the box parts folded into an accordion tend to move away from each other, this being all the more marked as these box parts are distant from the zone where the two flaps meet.

Avec les ébauches de boîtes selon les documents US2004/0217154 et NL2018273 , une même problématique est observée, à savoir que les parties de boîte pliées en accordéon ont tendance à s'écarter l'une de l'autre, ceci étant d'autant plus marqué que ces parties de boîte sont distantes de la zone où se rejoignent les organes mâle et femelle constituant les moyens de maintien des boîtes sous leur forme pliée et compressée.With box blanks according to documents US2004 / 0217154 and NL2018273 , the same problem is observed, namely that the box parts folded into an accordion tend to move away from one another, this being all the more marked as these box parts are distant from the area where they are join the male and female members constituting the means for holding the boxes in their folded and compressed form.

Enfin, comme abordé plus haut, une autre problématique rencontrée avec les ébauches de boîtes selon les documents antérieurs US8919635 , US2004/0217154 et NL2018273 est qu'il convient de respecter une procédure de pliage bien précise de telle sorte que les moyens de maintien des boîtes sous forme pliée et compressée soient tous deux accessibles au moment où il convient de les connecter (assembler).Finally, as discussed above, another problem encountered with the blanks of boxes according to previous documents US8919635 , US2004 / 0217154 and NL2018273 is that a very precise folding procedure should be followed so that the means for holding the boxes in folded and compressed form are both accessible when they need to be connected (assembled).

Résumé de de l'inventionSummary of the invention

Un des buts de la présente invention est de fournir une boîte pliable compressible, en particulier une boîte à pizza pliable compressible, dont on peut réduire la taille/le volume en assurant que la taille/le volume réduit obtenu puisse être conservé durablement sans que n'ait lieu une décompaction de la boîte comprimée. Plus particulièrement, un des buts de la présente invention est de fournir une ébauche d'une boîte pliable compressible, permettant de former une boîte dont la taille/le volume peut être ensuite réduit et maintenu sous cette forme réduite, par exemple après utilisation de la boîte et avant de la jeter.One of the aims of the present invention is to provide a compressible collapsible box, in particular a compressible collapsible pizza box, the size / volume of which can be reduced by ensuring that the reduced size / volume obtained can be maintained for a long time without n decompaction of the compressed box takes place. More particularly, one of the aims of the present invention is to provide a blank for a compressible collapsible box, making it possible to form a box whose size / volume can then be reduced and maintained in this reduced form, for example after use of the box. box and before throwing it away.

En parallèle, l'invention vise à procurer une ébauche de boîte pliable compressible qui, une fois sous sa forme comprimée, peut être maintenue sous cette forme de telle sorte que les parties de boîtes pliées (par exemple en accordéon) ne présentent que des d'espacements réduits entres elles et de telle sorte que cette forme comprimée ne présente pas d'excroissance et ne présente qu'un minimum d'arêtesAt the same time, the invention aims to provide a compressible collapsible box blank which, once in its compressed form, can be maintained in this form such that the folded box parts (for example accordion-shaped) only have dots. '' reduced spacings between them and so that this compressed form does not have any protuberances and has only a minimum of edges

Un autre objectif poursuivi par la présente invention est de procurer une ébauche de boîte pliable et compressible qui soit facile à fabriquer, c'est-à-dire pour laquelle les nombres de prédécoupe et/ou de plis à prévoir sont réduits, la taille/le volume de la boîte pouvant être ensuite réduit et maintenu sous cette forme réduite.Another objective pursued by the present invention is to provide a collapsible and compressible box blank which is easy to manufacture, that is to say for which the numbers of precuts and / or plies to be provided are reduced, the size / volume of the box can then be reduced and maintained in this reduced form.

Encore un autre objectif poursuivi par la présente invention est de procurer une ébauche de boîte pliable et compressible qui permette d'obtenir facilement et rapidement la boîte maintenue sous sa forme pliée et comprimée, en ayant à opérer un minimum de manipulations.Yet another object pursued by the present invention is to provide a collapsible and compressible box blank which makes it possible to easily and quickly obtain the box maintained in its folded and compressed form, while having to operate a minimum of handling.

A cette fin, il est prévu selon la présente invention, une ébauche d'une boîte pliable compressible comprenant :

  • un panneau supérieur,
  • un panneau inférieur,
  • un panneau arrière connectant ledit panneau supérieur avec ledit panneau inférieur,
  • des panneaux latéraux longitudinaux connectés au panneau inférieur,
  • un panneau latéral transversal connecté au panneau inférieur, et
  • au moins un moyen d'aide à la destruction,
  • au moins une prédécoupe faisant partie intégrante de ladite ébauche dans une première position de repos et s'étendant au départ de ladite ébauche dans une deuxième position selon laquelle ladite ébauche présente alors un évidement en lieu et place de ladite prédécoupe, ladite prédécoupe définissant un moyen de maintien de ladite boîte compressible lorsqu'elle est sous sa forme comprimée, ledit moyen de maintien étant muni d'un organe de connexion agencé pour être connecté à ou dans une zone de connexion,
    ladite ébauche étant caractérisée en ce que ledit moyen de maintien définit une ceinture ceinturant ladite boîte compressible sur l'ensemble de son pourtour lorsqu'elle est sous sa forme comprimée.
To this end, according to the present invention, there is provided a blank of a compressible collapsible box comprising:
  • a top panel,
  • a lower panel,
  • a rear panel connecting said upper panel with said lower panel,
  • longitudinal side panels connected to the lower panel,
  • a transverse side panel connected to the bottom panel, and
  • at least one means of aid in destruction,
  • at least one precut forming an integral part of said blank in a first rest position and extending from said blank in a second position according to which said blank then has a recess in place of said precut, said precut defining means for holding said compressible box when it is in its compressed form, said holding means being provided with a connection member arranged to be connected to or in a connection zone,
    said blank being characterized in that said retaining means defines a belt surrounding said compressible box over its entire periphery when it is in its compressed form.

Selon l'invention, ledit au moins un moyen d'aide à la destruction est disposé à travers ledit panneau supérieur et/ou ledit panneau inférieur et/ou ledit panneau arrière.According to the invention, said at least one destruction aid means is arranged through said upper panel and / or said lower panel and / or said rear panel.

Par les termes « ledit moyen de maintien définit une ceinture ceinturant ladite boîte compressible sur l'ensemble de son pourtour lorsqu'elle est sous sa forme comprimée », il est entendu, au sens de la présente invention, que le moyen de maintien s'enroule sur la totalité/l'ensemble d'une circonférence de la boîte comprimée, telle une ceinture. Les termes « pourtour » et « circonférence » ont la même signification selon la présente invention.By the terms "said retaining means defines a belt surrounding said compressible box over its entire circumference when it is in its compressed form", it is understood, within the meaning of the present invention, that the retaining means s' wraps around the whole / whole of a circumference of the compressed box, like a belt. The terms “periphery” and “circumference” have the same meaning according to the present invention.

Dans le cadre de la présente invention, il a été mis en évidence qu'un tel moyen de maintien définissant une ceinture ceinturant véritablement la boîte compressible sur l'ensemble de son pourtour lorsqu'elle est sous sa forme comprimée permet de résoudre au moins partiellement les problèmes de l'état de la technique mentionnés ci-dessus. En particulier, il a été montré qu'un tel moyen de maintien définissant une ceinture permet d'assurer que la boîte pliée, comprimée et ceinturée ne se décompacte pas, la taille/le volume réduit étant maintenu de façon permanente sans qu'aucune décompaction ne puisse avoir lieu. En effet, le ceinturage de la boîte pliée et comprimée fait en sorte les espacements entre les parties de boîte pliées (par exemple en accordéon) sont très significativement réduits et qu'il n'y a pas de décompaction possible dès lors que le moyen de maintien sous forme d'une ceinture exerce une force et une pression adéquate sur l'ensemble du pourtour de la boîte pliée et comprimée.In the context of the present invention, it has been demonstrated that such a holding means defining a belt genuinely encircling the compressible box over its entire periphery when it is in its compressed form makes it possible to at least partially resolve the problems of the state of the art mentioned above. In particular, it has been shown that such a holding means defining a belt makes it possible to ensure that the folded, compressed and belted box does not decompact, the reduced size / volume being maintained permanently without any decompaction. cannot take place. Indeed, the belt of the folded and compressed box ensures that the spacings between the folded box parts (for example in accordion) are very significantly reduced and that there is no decompaction possible since the means of holding in the form of a belt exerts adequate force and pressure over the entire circumference of the folded and compressed box.

En outre, une ébauche de boîte pliable compressible selon l'invention est parfaitement adéquate pour être stockée en occupant le minimum de place mais aussi pour être jetée dans des sachets en plastique sans les déchirer puisque la boîte pliée comprimée et ceinturée selon l'invention ne présente pas d'excroissance ni d'arêtes.In addition, a compressible collapsible box blank according to the invention is perfectly suitable for being stored taking up the minimum of space but also for being thrown into plastic bags without tearing them since the compressed and belted folded box according to the invention does not presents no protuberances or ridges.

Par ailleurs, selon l'invention, la prédécoupe est réalisée dans l'un des panneaux de la boîte pliable compressible et ne restreint pas l'usage de cette dernière. En effet, la prédécoupe est telle qu'elle ne fragilise pas la boîte, laquelle peut être utilisée normalement, c'est-à-dire qu'elle peut accueillir le même contenu que lorsqu'elle ne présente pas de prédécoupe.Furthermore, according to the invention, the precut is made in one of the panels of the compressible foldable box and does not restrict the use of the latter. In fact, the precut is such that it does not weaken the box, which can be used normally, that is to say that it can accommodate the same content as when it does not have a precut.

Cette prédécoupe présente une première position dite de repos selon laquelle elle fait partie intégrante d'un des panneaux de la boîte. Selon une seconde position, la prédécoupe s'étant au départ d'un des panneaux de la boîte, au moins une zone de cette prédécoupe restant reliée à l'un des panneaux de la boîte. Dans la seconde position, la prédécoupe se présente sous forme d'une ceinture de telle façon à constituer un moyen de maintien de ladite boîte pliable compressible lorsqu'elle est sous sa forme comprimée. En particulier, cette ceinture est prévue pour s'enrouler sur l'ensemble du pourtour (de la circonférence) de la boîte sous sa forme compressée de telle sorte que la boîte reste comprimée de façon définitive sans qu'une décompaction n'ait lieu.This precut has a first so-called rest position in which it forms an integral part of one of the panels of the box. According to a second position, the precut starting from one of the panels of the box, at least one zone of this precut remaining connected to one of the panels of the box. In the second position, the precut is in the form of a belt so as to constitute a means for holding said compressible foldable box when it is in its compressed form. In particular, this belt is designed to roll up around the entire perimeter (of the circumference) of the box in its compressed form so that the box remains permanently compressed without decompaction taking place.

Selon l'invention, la prédécoupe définit donc un moyen de maintien de ladite boîte pliable compressible sous sa forme comprimée.According to the invention, the precut therefore defines a means for maintaining said compressible foldable box in its compressed form.

De préférence, selon l'invention, ladite zone de connexion est définie par :

  1. a) ledit évidemment constituant une zone d'accueil et de connexion dudit organe de connexion lorsque ledit moyen de maintien ceinture ladite boîte comprimée sur l'ensemble de son pourtour ; ou
  2. b) un moyen de connexion situé sur ledit moyen de maintien, sensiblement à une extrémité opposée à celle comprenant ledit organe de connexion, ledit moyen de connexion constituant une zone d'accueil et de connexion dudit organe de connexion lorsque ledit moyen de maintien ceinture ladite boîte comprimée sur l'ensemble de son pourtour.
Preferably, according to the invention, said connection zone is defined by:
  1. a) said recess constituting a reception and connection zone for said connection member when said retaining means surrounds said compressed box over its entire periphery; or
  2. b) a connection means located on said holding means, substantially at an end opposite to that comprising said connection member, said connection means constituting a reception and connection zone of said connection member when said holding means surrounds said box compressed all around its perimeter.

Dans le premier cas de figure, l'organe de connexion présent au niveau du moyen de maintien s'insère dans l'évidement laissé par la prédécoupe (dès qu'elle est dans sa deuxième position) une fois que la boîte est sous sa forme comprimée et ceinturée. Plus concrètement, une fois que le moyen de maintien est enroulé autour de la boîte comprimée et ceinture véritablement la boîte comprimée sur l'ensemble de son pourtour, l'organe de connexion peut être insérer au moins partiellement dans une zone de connexion constituée par l'évidemment laissé par la prédécoupe (dès qu'elle est dans sa deuxième position). Cette insertion de l'organe de connexion dans l'évidemment assure le blocage de l'organe de connexion, ce qui permet d'assurer que le moyen de maintien (la ceinture) reste en place et exerce de façon continue et permanente une force et une pression adéquate sur l'ensemble du pourtour de la boîte pliée et comprimée. En particulier, l'insertion de l'organe de connexion dans l'évidement laissé par la prédécoupe (dès qu'elle est dans sa deuxième position) assure que le moyen de maintien (ceinture) reste en place sur l'ensemble du pourtour de la boîte pliée comprimée et que la force et la pression exercées par ce moyen de maintien soient maintenues en permanence afin d'empêcher toute décompaction.In the first case, the connection member present at the level of the holding means is inserted into the recess left by the precut (as soon as it is in its second position) once the box is in its form. compressed and belted. More concretely, once the retaining means is wound around the compressed box and truly surrounds the compressed box over its entire periphery, the connection member can be inserted at least partially in a connection zone constituted by the 'obviously left by the precut (as soon as it is in its second position). This insertion of the connection member into the recess secures the locking of the connection member, which ensures that the holding means (the belt) remains in place and continuously and permanently exerts a force and adequate pressure all around the folded and compressed box. In particular, the insertion of the connection member into the recess left by the precut (as soon as it is in its second position) ensures that the holding means (belt) remains in place over the entire periphery of the the folded box compressed and that the force and pressure exerted by this means of maintenance are maintained permanently in order to prevent decompaction.

Dans le second cas de figure, l'organe de connexion présent au niveau du moyen de maintien s'insère dans un moyen de connexion situé sur le moyen de maintien lui-même. Ce moyen de connexion est situé sensiblement à une extrémité opposée à celle comprenant ledit organe de connexion sur le moyen de maintien. Plus concrètement, une fois que le moyen de maintien est enroulé autour de la boîte comprimée et ceinture véritablement la boîte comprimée sur l'ensemble de son pourtour, l'organe de connexion peut être insérer au moins partiellement dans le moyen de connexion. Cette insertion de l'organe de connexion dans le moyen de connexion assure le blocage de l'organe de connexion, ce qui permet d'assurer que le moyen de maintien (la ceinture) reste en place et exerce de façon continue et permanente une force et une pression adéquate sur l'ensemble du pourtour de la boîte pliée et comprimée. En particulier, l'insertion de l'organe de connexion dans le moyen de connexion assure que le moyen de maintien (ceinture) reste en place sur l'ensemble du pourtour de la boîte pliée comprimée et que la force et la pression exercées par ce moyen de maintien soient maintenues en permanence afin d'empêcher toute décompaction.In the second case, the connection member present at the level of the holding means is inserted into a connection means located on the holding means itself. This connection means is located substantially at an end opposite to that comprising said connection member on the holding means. More concretely, once the retaining means is wound around the compressed box and truly surrounds the compressed box around its entire periphery, the connection member can be inserted at least partially into the connection means. This insertion of the connection member into the connection means ensures the locking of the connection member, which ensures that the holding means (the belt) remains in place and continuously and permanently exerts a force. and adequate pressure all around the folded and compressed box. In particular, the insertion of the connection member into the connection means ensures that the holding means (belt) remains in place over the entire periphery of the compressed folded box and that the force and pressure exerted by this holding means are maintained at all times to prevent decompaction.

De façon avantageuse, une ébauche de boîte pliable compressible selon l'invention minimise le nombre de prédécoupe à prévoir lors de sa fabrication. En effet, une seule et même prédécoupe joue à la fois le rôle d'organe mâle et d'organe femelle puisque c'est l'évidement laissé par le moyen de maintien (la ceinture jouant le rôle d'organe mâle) ou le moyen de connexion présent sur le moyen de maintien lui-même qui constituent l'organe femelle dans lequel s'insère l'organe de connexion du moyen de maintien. Ceci est avantageux par rapport aux moyens de maintien connus des documents US8919635 , US2004/0217154 et NL2018273 qui consistent en la coopération de deux prédécoupes distinctes.Advantageously, a compressible foldable box blank according to the invention minimizes the number of precuts to be provided during its manufacture. Indeed, one and the same precut plays both the role of male organ and female organ since it is the recess left by the holding means (the belt playing the role of male organ) or the means connection present on the holding means itself which constitute the female member into which the connection member of the holding means is inserted. This is advantageous compared to the known means of maintaining documents. US8919635 , US2004 / 0217154 and NL2018273 which consist of the cooperation of two distinct pre-cuts.

De façon avantageuse également, l'obtention d'une boîte pliée comprimée et maintenue sous sa forme comprimée est particulièrement aisée avec une ébauche de boîte pliable et compressible selon l'invention. En effet, au contraire des boîtes pliables et compressibles connues de l'état de la technique, il ne s'agit pas ici de faire coopérer deux moyens de maintien situés au niveau de parois ou d'angles opposés en respectant au préalable une procédure de pliage et de compression bien précise (sans quoi l'un ou l'autre ou les deux moyens de maintien pourraient ne plus être accessible(s)). Selon la présente invention, l'évidemment laissé par la prédécoupe dès le moment où elle est dans sa deuxième position est accessible à tout moment et sur toute sa longueur, ce qui facilite grandement l'insertion de l'organe de connexion du moyen de maintien dans cet évidement pour assurer que le moyen de maintien (ceinture) reste en place sur l'ensemble du pourtour de la boîte pliée comprimée et que la force et la pression exercées par ce moyen de maintien soient maintenues en permanence afin d'empêcher toute décompaction. Il en va de même lorsque l'organe de connexion s'insère dans un moyen de connexion situé sur le moyen de maintien lui-même.Also advantageously, obtaining a folded box compressed and maintained in its compressed form is particularly easy with a foldable and compressible box blank according to the invention. Indeed, unlike the foldable and compressible boxes known from the state of the art, it is not a question here of making cooperate two retaining means located at the level of walls or at opposite angles while first respecting a very precise folding and compression procedure (otherwise one or the other or both holding means could no longer be accessible). According to the present invention, the recess left by the precut from the moment it is in its second position is accessible at any time and over its entire length, which greatly facilitates the insertion of the connection member of the holding means. in this recess to ensure that the retaining means (belt) remains in place over the entire periphery of the compressed folded box and that the force and pressure exerted by this retaining means are permanently maintained in order to prevent any decompaction . The same applies when the connection member is inserted into a connection means located on the holding means itself.

Avantageusement, selon l'invention, ladite prédécoupe définissant un moyen de maintien de ladite boîte pliable compressible est présente au niveau dudit panneau inférieur. Toutefois, il n'est pas exclu que ladite prédécoupe définissant un moyen de maintien de ladite boîte pliable compressible soit présente au niveau dudit panneau supérieur.Advantageously, according to the invention, said precut defining a means for maintaining said compressible foldable box is present at the level of said lower panel. However, it is not excluded that said precut defining a means for maintaining said compressible foldable box is present at said upper panel.

De préférence, selon l'invention, lesdits panneaux latéraux longitudinaux comprennent des moyens de connexion agencés pour relier ces panneaux latéraux longitudinaux au panneau arrière et au panneau latéral transversal. Les moyens de connexion sont configurés pour permettre à l'utilisateur de plier et de déployer la boîte sans besoin d'outils supplémentaires pour retenir les parois des panneaux ensemble. Il n'est pas nécessaire d'utiliser des moyens rapides comme de la colle ou des agrafes, en utilisant l'ébauche de la boîte pliable compressible de la présente invention : l'assemblage est rapide et facile.Preferably, according to the invention, said longitudinal side panels comprise connection means arranged to connect these longitudinal side panels to the rear panel and to the transverse side panel. The connection means are configured to allow the user to fold and unfold the box without the need for additional tools to hold the walls of the panels together. It is not necessary to use quick means such as glue or staples, using the compressible collapsible box blank of the present invention: assembly is quick and easy.

Avantageusement, selon l'invention, ledit panneau supérieur est connecté à des panneaux latéraux longitudinaux et éventuellement à un panneau latéral transversal.Advantageously, according to the invention, said top panel is connected to longitudinal side panels and possibly to a transverse side panel.

Selon l'invention, le panneau supérieur de l'ébauche de la boîte pliable compressible n'est pas caractérisé par rapport à la présence ou à l'absence d'un ou de plusieurs panneaux de parois latérales. L'ébauche de la boîte pliable compressible de l'invention peut présenter par conséquent un panneau supérieur ayant seulement un seul panneau latéral connecté, en particulier un panneau latéral transversal. Dans un autre mode de réalisation, l'ébauche de la boîte pliable compressible de l'invention inclut un panneau supérieur ayant trois panneaux latéraux connectés. Dans ce dernier mode de réalisation, l'ébauche de la boîte pliable compressible comprend trois panneaux latéraux au niveau du panneau inférieur et trois panneaux latéraux au niveau du panneau supérieur.According to the invention, the top panel of the compressible collapsible box blank is not characterized by the presence or absence of one or more side wall panels. The compressible collapsible box blank of the invention may therefore have a top panel having only a single side panel connected, in particular a transverse side panel. In another embodiment, the blank for the collapsible, compressible box of the invention includes a top panel having three connected side panels. In the latter embodiment, the compressible collapsible box blank includes three side panels at the bottom panel and three side panels at the top panel.

De préférence, selon l'invention, ledit au moins un moyen d'aide à la destruction s'étend en outre à travers ledit panneau latéral transversal présent au niveau dudit panneau inférieur.Preferably, according to the invention, said at least one destruction aid means further extends through said transverse side panel present at said lower panel.

Avantageusement, selon l'invention, ledit au moins un moyen d'aide à la destruction s'étend en outre à travers ledit panneau latéral transversal présent au niveau dudit panneau supérieur.Advantageously, according to the invention, said at least one destruction aid means further extends through said transverse side panel present at said upper panel.

Un trait caractéristique de l'ébauche de la boîte pliable compressible de l'invention réside dans le fait que ledit au moins un moyen d'aide à la destruction traverse les panneaux supérieur et/ou arrière et/ou inférieur et s'étend préférentiellement sensiblement parallèlement à l'axe longitudinal de l'ébauche. Dans le cas où d'autres panneaux latéraux seraient connectés au panneau inférieur ou au panneau supérieur, ledit au moins un moyen d'aide à la destruction peut également s'étendre à travers ces autres panneaux latéraux.A characteristic feature of the blank of the compressible collapsible box of the invention lies in the fact that said at least one destruction aid means passes through the upper and / or rear and / or lower panels and preferably extends substantially parallel to the longitudinal axis of the blank. In the event that other side panels are connected to the lower panel or to the upper panel, said at least one destruction aid means may also extend through these other side panels.

Selon un mode de réalisation possible, ledit au moins un moyen d'aide à la destruction traverse les panneaux supérieur et/ou arrière et/ou inférieur et s'étend préférentiellement sensiblement transversalement à l'axe longitudinal de l'ébauche.According to one possible embodiment, said at least one destruction aid means passes through the upper and / or rear and / or lower panels and preferably extends substantially transversely to the longitudinal axis of the blank.

Par ailleurs, la boîte compressible selon l'invention peut comprendre plusieurs étages. Dans ce cas, au moins un panneau additionnel intermédiaire situé entre le panneau supérieur et le panneau inférieur est présent et est traversé par ledit au moins moyen d'aide à la destruction. De préférence, ledit au moins un panneau additionnel intermédiaire présente une taille (des dimensions) identique à celles des panneaux supérieur et inférieur.Furthermore, the compressible box according to the invention can comprise several stages. In this case, at least one additional intermediate panel located between the upper panel and the lower panel is present and is traversed by said at least means of aid for destruction. Preferably, said at least one additional intermediate panel has a size (dimensions) identical to those of the upper and lower panels.

De préférence, selon l'invention, ledit au moins un moyen d'aide à la destruction se présente sous la forme d'une fente, d'une perforation ou d'un pli, en particulier sous forme de perforations préférentiellement sensiblement parallèles à l'axe longitudinal de l'ébauche. Il est entendu, selon l'invention, que le moyen d'aide à la destruction n'est pas forcément rectiligne mais qu'il peut par exemple se présenter sous la forme d'un zigzag. Selon l'invention, les cannelures d'un carton ondulé utilisé pour former les parois de la boite peuvent constituer un moyen d'aide à la destruction.Preferably, according to the invention, said at least one destruction aid means is in the form of a slot, a perforation or a fold, in particular in the form of perforations preferably substantially parallel to the 'longitudinal axis of the blank. It is understood, according to the invention, that the destruction aid means is not necessarily rectilinear but that it may for example be in the form of a zigzag. According to the invention, the grooves of a corrugated cardboard used to form the walls of the box can constitute a means of aid in destruction.

Selon un mode de réalisation selon l'invention, la prédécoupe (c'est-à-dire la ceinture) comprend à son extrémité libre ou à proximité de son extrémité libre, une encoche en tant qu'organe de connexion prévu pour être engagé dans l'évidemment laissé par la prédécoupe dès le moment où elle est dans sa deuxième position ou dans le moyen de connexion situé sur le moyen de maintien pour assurer le maintien de la boîte compressible sous sa forme comprimée. Il est bien entendu que toute autre forme adéquate d'un organe de connexion tombe sous le couvert de la présente invention.According to one embodiment according to the invention, the precut (that is to say the belt) comprises at its free end or near its free end, a notch as a connection member intended to be engaged in the obvious left by the precut from the moment it is in its second position or in the connection means located on the holding means to ensure the maintenance of the compressible box in its form compressed. It is understood that any other suitable form of a connection member falls under the cover of the present invention.

La présente invention porte également sur une boîte pliable compressible formée au départ d'une ébauche de boîte pliable compressible suivant l'invention.The present invention also relates to a compressible collapsible box formed from a compressible collapsible box blank according to the invention.

The top panel 1, according to the embodiment illustrated in figure 1 , is also connected / connected to longitudinal side panels and to a transverse side panel 9 via fold lines. The fold lines allow the user to form a box from the blank of the compressible foldable box according to the invention by folding the different panels along said fold lines.

En utilisant les moyens de connexion 5, les panneaux latéraux longitudinaux 4 connectés/reliés au panneau inférieur 2 peuvent être facilement connectés au panneau latéral transversal 10 et au panneau arrière 3 adjacents du panneau inférieur 2. Comme illustré, les moyens de connexion 5 comprennent un téton 7 sous forme circulaire agencé pour être inséré dans les orifices 8, ceci afin d'assurer la solidarisation du panneau arrière 3 et du panneau latéral transversal 10 avec les panneaux latéraux longitudinaux 4. En principe n'importe quel moyen de connexion permettant aux panneaux d'être connectés sans moyens additionnels peut être utilisé dans le contexte de la présente invention.By using the connection means 5, the longitudinal side panels 4 connected / linked to the bottom panel 2 can be easily connected to the transverse side panel 10 and the adjacent rear panel 3 of the bottom panel 2. As illustrated, the connection means 5 comprise a stud 7 in circular form arranged to be inserted into the orifices 8, in order to ensure the securing of the rear panel 3 and the transverse side panel 10 with the longitudinal side panels 4. In principle any means of connection allowing the panels to be connected without additional means can be used in the context of the present invention.

Comme indiqué ci-dessus et selon le mode de réalisation à la figure 1, les moyens de connexion 5 incluent une languette circulaire 7 (téton circulaire) qui s'insère dans un trou 8 pratiqué dans les panneaux latéraux transversaux 9, 10 adjacents ou dans un trou 8 pratiqué dans le panneau arrière 3. En pliant la languette circulaire 7 vers l'intérieur à travers le trou 8, les différents panneaux sont solidarisés et maintenus en position debout, c'est-à-dire dans une position sensiblement perpendiculaire par rapport aux panneaux supérieur et inférieur.As indicated above and according to the embodiment on figure 1 , the connection means 5 include a circular tongue 7 (circular stud) which fits into a hole 8 made in the transverse side panels 9, 10 adjacent or in a hole 8 made in the rear panel 3. By bending the circular tongue 7 towards the interior through the hole 8, the various panels are joined together and held in an upright position, that is to say in a position substantially perpendicular to the upper and lower panels.

Selon le mode de réalisation illustré à la figure 1, le panneau inférieur 2 comprend une prédécoupe 11 et des moyens d'aide à la destruction 6 qui s'étendent sensiblement parallèlement à l'axe longitudinal de l'ébauche à travers les panneaux supérieur 2, inférieur 1 et arrière 3 mais aussi à travers les panneaux latéraux transversaux 9, 10 reliés respectivement au panneau supérieur 1 et inférieur 2. La prédécoupe 11 définit un moyen de maintien de la boîte compressible lorsqu'elle est sous sa forme comprimée. Selon une première position de repos, la prédécoupe 11 fait partie intégrante du panneau inférieur 2 tandis que, selon une seconde position, cette prédécoupe 11 s'étend au départ du panneau inférieur 2 de telle sorte à former une ceinture (une languette) mais aussi à laisser un évidemment 14 dans le panneau inférieur 2.According to the embodiment illustrated in figure 1 , the lower panel 2 comprises a pre-cut 11 and destruction aid means 6 which extend substantially parallel to the longitudinal axis of the blank through the upper 2, lower 1 and rear 3 panels but also through the transverse side panels 9, 10 connected respectively to the upper 1 and lower panel 2. The pre-cut 11 defines a means for maintaining the compressible box when it is in its compressed form. According to a first rest position, the precut 11 forms an integral part of the lower panel 2 while, according to a second position, this precut 11 extends from the lower panel 2 so as to form a belt (a tongue) but also to leave a recess 14 in the lower panel 2.

Selon le mode de réalisation illustré, la prédécoupe 11 est munie, à son extrémité, d'un organe de connexion 12 prévu pour être inséré, après compression de la boîte compressible, dans l'évidemment 14 laissé par la prédécoupe 11 dès son passage dans sa deuxième position. La présence de cette prédécoupe 11 définissant un moyen de maintien (ou un moyen liant) sous forme d'une ceinture de la boîte pliable compressible lorsqu'elle est sous sa forme comprimée et la présence, au niveau du moyen de maintien, d'un organe de connexion s'insérant dans l'évidemment 14 laissé par la prédécoupe 11 dès son passage dans sa deuxième position (voir à la figure 5C), assure que la boîte pliable une fois comprimée reste dans cet état comprimé, ce qui contribue à faciliter l'élimination de la boîte. Notons que, selon l'invention, cette prédécoupe 11 n'affecte pas la facilité de montage de la boîte ni la solidité de cette dernière.According to the illustrated embodiment, the precut 11 is provided, at its end, with a connection member 12 intended to be inserted, after compression of the compressible box, in the recess 14 left by the precut 11 as soon as it passes through. its second position. The presence of this precut 11 defining a holding means (or a binding means) in the form of a belt of the compressible foldable box when it is in its compressed form and the presence, at the level of the holding means, of a connection member fitting into the recess 14 left by the pre-cut 11 as soon as it passes into its second position (see figure 5C ), ensures that the collapsible box when compressed remains in this compressed state, which helps facilitate disposal of the box. Note that, according to the invention, this precut 11 does not affect the ease of assembly of the box or the strength of the latter.

La figure 2 illustre une autre ébauche de boîte pliable compressible dépliée selon l'invention où sont présentes les mêmes caractéristiques que celles décrites pour la figure 1.The figure 2 illustrates another blank compressible collapsible box unfolded according to the invention in which the same characteristics as those described for the figure 1 .

La figure 3 illustre une autre ébauche de boîte pliable compressible dépliée selon l'invention où sont présentes les mêmes caractéristiques que celles décrites pour les figures 1 et 2, à ceci près qu'il s'agit ici d'une boîte pliable compressible à double étage. En effet, comme illustré, cette boîte de la figure 3 comprend un panneau additionnel intermédiaire 13 situé entre le panneau supérieur 1 et le panneau inférieur 2 est présent et est traversé par ledit au moins moyen d'aide à la destruction 6.The figure 3 illustrates another blank compressible collapsible box unfolded according to the invention in which the same characteristics as those described for the figures 1 and 2 , except that this is a compressible collapsible box with two levels. Indeed, as illustrated, this box of the figure 3 comprises an additional intermediate panel 13 located between the upper panel 1 and the lower panel 2 is present and is crossed by said at least means of assistance for destruction 6.

La figure 4 illustre une autre ébauche de boîte pliable compressible dépliée selon l'invention où sont présentes les mêmes caractéristiques que celles décrites pour la figure 3.The figure 4 illustrates another blank compressible collapsible box unfolded according to the invention in which the same characteristics as those described for the figure 3 .

En pratique et comme illustré à la figure 5, lorsqu'il s'agit, après usage, de comprimer la boîte avant de la jeter ou de la recycler, il convient de faire passer la prédécoupe 11 de sa première position de repos, selon laquelle elle fait partie intégrante du panneau inférieur 2 (figure 5A), dans sa seconde position, selon laquelle elle s'étend au départ du panneau inférieur 2 de telle sorte à former une ceinture (languette) mais aussi de telle sorte à laisser un évidemment 14 dans le panneau inférieur 2 (figure 5B). La ceinture ou languette présente alors une extrémité libre désolidarisée du panneau inférieur 2 et une extrémité liée restant reliée au panneau inférieur 2.In practice and as illustrated in figure 5 , when, after use, it is a question of compressing the box before throwing it away or recycling it, it is advisable to pass the pre-cut 11 from its first rest position, according to which it forms an integral part of the lower panel 2 ( figure 5A ), in its second position, according to which it extends from the lower panel 2 so as to form a belt (tongue) but also so as to leave a recess 14 in the lower panel 2 ( figure 5B ). The belt or tongue then has a free end detached from the lower panel 2 and a linked end remaining connected to the lower panel 2.

Ensuite, comme illustré à la figure 5C il convient d'effectuer un pliage et une compression de la boîte à l'aide des moyens d'aide à la destruction 6 qui s'étendent. Selon le mode de réalisation illustré, trois moyens d'aide à la destruction 6 sont présents et la boîte sera donc pliée/compactée en trois parties de boîte pliées qui vont être positionnées les unes sur les autres de telle façon à obtenir une forme comprimée de la boîte pliable compressible. Une fois cette forme comprimée de la boîte obtenue, la prédécoupe 11 formant une ceinture est alors utilisée pour véritablement ceinturer (entourer, encercler) les trois parties positionnées les unes sur les autres et ainsi assurer le maintien de la boîte sous sa forme comprimée en évitant toute décompaction ultérieure par ceinturage de la boîte pliée comprimée sur l'ensemble de son pourtour (figure 5D). Selon le mode de réalisation illustré à la figure 5D et comme illustré plus en détail à la figure 6, la prédécoupe 11 formant une ceinture (languette, moyen de maintien) est munie d'un organe de connexion 12 (ici sous forme d'un crochet) prévu pour être insérer, après compression de la boîte pliable compressible, dans un moyen de connexion 15 (ici sous forme d'une encoche) situé sur le moyen de maintien 11 (la prédécoupe) lui-même. Comme illustré, le moyen de connexion 15 est situé à une extrémité opposée à celle comprenant l'organe de connexion 12 sur le moyen de maintien 11. Ceci permet d'assurer le maintien de la boîte sous sa forme comprimée en évitant toute décompaction ultérieure. En particulier, au moins une partie du crochet vient en butée contre une des parois de l'encoche. La présente invention a été décrite en relation avec des modes de réalisations spécifiques, qui ont une valeur purement illustrative et ne doivent pas être considérés comme limitatifs. D'une manière générale, il apparaîtra évident pour l'homme du métier que la présente invention n'est pas limitée aux exemples illustrés et/ou décrits ci-dessus.Then, as shown in figure 5C the box should be folded and compressed using the destruction aid means 6 which extend. According to the illustrated embodiment, three destruction aid means 6 are present and the box will therefore be folded / compacted into three folded box parts which will be positioned on top of each other so as to obtain a compressed shape of the compressible collapsible box. Once this compressed form of the box has been obtained, the precut 11 forming a belt is then used to truly surround (surround, encircle) the three parts positioned one on top of the other and thus ensure the maintenance of the box in its compressed form while avoiding any subsequent decompaction by girdling the folded box compressed over its entire perimeter ( figure 5D ). According to the embodiment illustrated in figure 5D and as illustrated in more detail at figure 6 , the precut 11 forming a belt (tongue, holding means) is provided with a connection member 12 (here in the form of a hook) intended to be inserted, after compression of the compressible foldable box, into a connection means 15 (here in the form of a notch) located on the holding means 11 (the pre-cut) itself. As illustrated, the connection means 15 is located at an end opposite to that comprising the connection member 12 on the retaining means 11. This makes it possible to maintain the box in its compressed form while avoiding any subsequent decompaction. In particular, at least part of the hook comes into abutment against one of the walls of the notch. The present invention has been described in relation to specific embodiments, which have a purely illustrative value and should not be considered as limiting. In general, it will appear obvious to those skilled in the art that the present invention is not limited to the examples illustrated and / or described above.

La présence de numéros de référence aux dessins ne peut être considérée comme limitative, y compris lorsque ces numéros sont indiqués dans les revendications.The presence of reference numbers in the drawings cannot be considered as limiting, including when these numbers are indicated in the claims.

L'usage des verbes « comprendre », « inclure », « comporter », ou toute autre variante, ainsi que leurs conjugaisons, ne peut en aucune façon exclure la présence d'éléments autres que ceux mentionnés.The use of the verbs "to understand", "to include", "to include", or any other variant, as well as their conjugations, can in no way exclude the presence of elements other than those mentioned.

L'usage de l'article indéfini « un », « une », ou de l'article défini « le », « la » ou « l' », pour introduire un élément n'exclut pas la présence d'une pluralité de ces éléments.The use of the indefinite article "a", "a", or of the definite article "the", "the" or "the", to introduce an element does not exclude the presence of a plurality of these elements.
