Abstract

The box is made from a separate lid and base, the lid being made from a panel with side flaps connected by fold lines which allow the top to be laid out flat prior to use and folded when required into a parallelepiped shape. Two of its opposite side flaps have cut-out holes. The base of the box has a panel (201) with flaps (202 - 205) forming its sides, connected by pleated corners (210 - 213). Two opposite side flaps have cut-out holes (214, 215). When the lid is fitted to the bottom of the box the side holes are aligned and are joined together by an inner connecting element (216) made from a hollow piece of moulded plastics. Each connecting element can be in two sections with a slit between them for a string or ribbon.

Description

La présente invention concerne une boîte pâtissière pliante formée d'un fond et d'un couvercle, emboîtés.The present invention relates to a folding pastry box formed by a bottom and a lid, fitted together.

Les boîtes appelées « boîtes pâtissières » sont des boîtes en général en carton, présentant des parties pliées, dont le couvercle est relié au fond. Le couvercle est constitué de trois volets munis de lignes de pliage et rabattus. Le panneau du couvercle est relié par une articulation à l'un des quatre volets bordant le panneau du fond de la boîte. Les volets du fond comme ceux du couvercle se déploient pour prendre une forme parallélépipédique.The boxes called “pastry boxes” are boxes generally made of cardboard, having folded parts, the lid of which is connected to the bottom. The cover consists of three flaps fitted with fold lines and folded down. The cover panel is connected by a hinge to one of the four flaps bordering the panel at the bottom of the box. The flaps of the bottom like those of the cover deploy to take a parallelepiped shape.

De telles boîtes pâtissières, utilisées principalement en pâtisserie, servent également dans des domaines voisins, par exemple pour emballer des produits comme des pizzas.Such pastry boxes, used mainly in pastry making, are also used in neighboring fields, for example for packaging products such as pizzas.

Dans tous les cas, ces boîtes présentent plusieurs inconvénients à l'utilisation.In all cases, these boxes have several disadvantages in use.

Tout d'abord pour placer les produits dans la boîte, sur le comptoir, il faut déployer l'ensemble solidaire formé du fond et du couvercle, ce qui présente un certain en-combrement. La mise en place des produits à l'intérieur du fond n'est pas simple s'il s'agit de produits relativement fragiles, surtout en fin de remplissage du fond. Or, pour que les produits soient tenus et ne s'abîment pas pendant le transport, il faut que la boîte soit pratiquement remplie. Cela signifie qu'en fonction des produits à emballer on choisira la dimension de la boîte.First of all to place the products in the box, on the counter, it is necessary to deploy the integral assembly formed by the bottom and the cover, which has a certain size. The installation of products inside the bottom is not simple if they are relatively fragile products, especially at the end of filling the bottom. However, for the products to be held and not to be damaged during transport, the box must be practically filled. This means that depending on the products to be packaged, the size of the box will be chosen.

On rencontre les mêmes difficultés lorsqu'il s'agit de sortir les produits de la boîte.We encounter the same difficulties when it comes to getting products out of the box.

Comme par ailleurs le couvercle est relié au fond, il n'est pas très esthétique de présenter la boîte telle quelle.As the cover is also connected to the bottom, it is not very aesthetic to present the box as it is.

La seule solution consiste à couper le couvercle. Mais il subsistera alors le fond bordé par ses volets. Pour faciliter l'accès au produit contenu dans le fond, il est possible de couper les volets ou du moins de les entailler pour les ouvrir.The only solution is to cut the cover. But there will then remain the bottom bordered by its shutters. To facilitate access to the product contained in the bottom, it is possible to cut the flaps or at least notch them to open them.

Une autre difficulté est que le couvercle étant réalisé dans le même flanc de carton que le fond, il n'est pas possible de choisir une décoration ou une matière différente pour le couvercle de celle du fond. Or, les fonctions du couvercle et du fond sont différentes. Le fond doit recevoir les produits qui peuvent éventuellement être humides, aussi est-il parfois nécessaire de garnir le fond d'une feuille n'absorbant pas l'humidité. Le couvercle qui constitue l'élément le plus apparent de la boîte pourrait être en une matière différente de celle du fond.Another difficulty is that the cover being made in the same side of cardboard as the bottom, it is not possible to choose a different decoration or material for the bottom cover. However, the functions of the cover and the bottom are different. The bottom must receive the products which can possibly be wet, so it is sometimes necessary to garnish the bottom with a sheet that does not absorb moisture. The lid which constitutes the most visible element of the box could be made of a different material from that of the bottom.

Enfin, les produits à emballer n'ont pas toujours la même hauteur, aussi faut-il stocker des boîtes de hauteurs différentes en fonction des produits à emballer.Finally, the products to be packaged do not always have the same height, so it is necessary to store boxes of different heights depending on the products to be packaged.

Il existe également une autre solution mais peu répandue à savoir celle des boîtes usuelles, non pliantes, formées d'un fond et d'un couvercle séparés. Mais cette solution a pratiquement les mêmes inconvénients que les boîtes pliantes : il est délicat d'y placer des produits fragiles ou de grandes dimensions (et relativement souples) comme des pizzas. Ces mêmes difficultés existent à l'utilisation, pour accéder aux produits. Enfin, comme il n'y a pas de charnière qui assure une certaine rigidité, la boîte fermée reste très souple sauf si l'on utilise un carton ou une matière plastique de rigidité suffisante, ce qui renchérit la boîte. Or, cette souplesse serait particulièrement gênante pour des boîtes de grandes dimensions, par exemple pour des pizzas.There is also another solution, but not widely used, namely that of the usual, non-folding boxes, formed from a separate bottom and cover. But this solution has practically the same disadvantages as folding boxes: it is difficult to place fragile or large (and relatively flexible) products in it, such as pizza. These same difficulties exist in use, to access products. Finally, as there is no hinge which ensures a certain rigidity, the closed box remains very flexible unless a cardboard or a plastic material of sufficient rigidity is used, which makes the box more expensive. However, this flexibility would be particularly troublesome for large boxes, for example for pizzas.

La présente invention a pour but de remédier à ces inconvénients et se propose de créer une boîte pâtissière, de fabrication extrêmement simple, de très faible encombrement à vide, qui se met en place et se ferme facilement et rapidement et permette de donner au fond et au couvercle des caractéristiques fonctionnelles et esthétiques différentes.The object of the present invention is to remedy these drawbacks and proposes to create a pastry box, of extremely simple manufacture, of very small bulk when empty, which is put in place and closes easily and quickly and makes it possible to give the bottom and different functional and aesthetic characteristics on the cover.

A cet effet, l'invention concerne une boîte pâtissière caractérisée en ce que :

  • le couvercle est séparé du fond,
  • le couvercle est formé d'un panneau bordé par des volets, l'ensemble étant muni de lignes de pliage pour que les volets puissent être rabattus à plat ou déployés en position d'utilisation pour donner au couvercle une forme de parallélépipède,
  • deux volets opposés étant munis d'une découpe,
  • le fond comprend un panneau bordé de volets formant les côtés du fond,
les volets restant reliés par des coins non collés munis chacun d'un pli suivant une bissectrice, deux volets opposés étant munis d'une découpe,
  • un organe d'accrochage placé dans la découpe de chaque volet et relié au volet, cet organe d'accrochage dépassant vers l'extérieur du volet, pour venir se loger dans la découpe correspondante du couvercle,
seulement deux côtés opposés du couvercle et du fond reçoivent les organes d'accrochage.To this end, the invention relates to a pastry box characterized in that:
  • the cover is separated from the bottom,
  • the cover is formed by a panel bordered by flaps, the assembly being provided with fold lines so that the flaps can be folded flat or deployed in the position of use to give the cover a shape of a parallelepiped,
  • two opposite flaps being provided with a cutout,
  • the bottom comprises a panel bordered by shutters forming the sides of the bottom,
the remaining flaps connected by non-glued corners each provided with a fold along a bisector, two opposite flaps being provided with a cutout,
  • a fastening member placed in the cutout of each shutter and connected to the shutter, this fastening member protruding towards the outside of the shutter, to be housed in the corresponding cutout of the cover,
only two opposite sides of the cover and the bottom receive the hooking members.

Le couvercle formé de volets se réalise par exemple comme le couvercle d'une boîte pâtissière classique sauf qu'il comporte quatre volets et non pas trois et que deux volets opposés sont munis d'une découpe de préférence allongée. Un tel produit est d'une réalisation particulièrement simple en cartonnerie.The cover formed by flaps is produced, for example, like the cover of a conventional pastry box except that it has four flaps and not three and that two opposite flaps are provided with a cut which is preferably elongated. Such a product is of a particularly simple production in cardboard.

Le couvercle peut également être réalisé en carton ondulé plié et assemblé au moment de son utilisation.The cover can also be made of folded corrugated cardboard and assembled at the time of use.

Le fond est d'une réalisation encore plus simple et il ne comporte aucune partie collée. Il est découpé et rainé suivant les lignes de pliage entre le panneau et les volets. Il y a des lignes de pliage supplémentaires au niveau des coins reliant chaque fois deux volets. Ces coins sont séparés aux volets par des lignes de pliage, par exemple rainées ; et chaque coin a une ligne de pliage suivant la bissectrice. Les coins forment ainsi des soufflets lorsque les volets sont relevés.The bottom is of an even simpler realization and it does not have any glued part. It is cut and grooved along the fold lines between the panel and the shutters. There are additional fold lines at the corners connecting two flaps each time. These corners are separated from the flaps by fold lines, for example grooved; and each corner has a fold line following the bisector. The corners thus form bellows when the flaps are raised.

Pour la mise en place des produits dans le fond, celui-ci reste ouvert, les volets rabattus ou du moins très évasés. Cela facilite considérablement l'accès au fond pour la mise en place ou la prise des produits.For the installation of products in the bottom, it remains open, the flaps folded or at least very flared. This considerably facilitates access to the bottom for placing or taking the products.

Une fois le fond rempli de produits, il suffit de relever les bords et de comprimer légèrement les deux volets munis des organes d'accrochage pour engager le couvercle par-dessus afin qu'il s'accroche sur les deux organes d'accrochage. La charnière formée par les lignes de pliage des volets aux panneaux ou des volets entre eux donne à l'ensemble une certaine élasticité poussant les volets vers l'extérieur, c'est-à-dire maintenant les organes d'accrochage dans les découpes des volets correspondants du couvercle.Once the bottom is filled with products, it suffices to raise the edges and slightly compress the two flaps fitted with the hooking members to engage the cover over so that it hooks onto the two hooking members. The hinge formed by the fold lines of the shutters to the panels or of the shutters between them gives the assembly a certain elasticity pushing the shutters outwards, that is to say now the hooking members in the cutouts of the corresponding flaps of the cover.

L'excellente tenue des moyens d'accrochage assemblant la boîte permet de réaliser le couvercle avec des dimensions plus grandes que celles du fond de manière à faciliter la mise en place du couvercle ou son enlèvement, bien plus facilement que si l'assemblage était étroitement ajusté.The excellent resistance of the attachment means assembling the box makes it possible to produce the cover with dimensions larger than those of the bottom so as to facilitate the fitting of the cover or its removal, much more easily than if the assembly were tightly adjusted.

Pour l'ouverture, il suffit de comprimer les organes d'accrochage pour les faire rentrer et soulever le couvercle, le fond étant retenu par le poids des produits qu'il contient.For opening, it suffices to compress the fastening members to bring them in and lift the cover, the bottom being retained by the weight of the products it contains.

Suivant une caractéristique particulièrement avantageuse de l'invention, les organes d'accrochage sont des pièces creuses de faible épaisseur, par exemple, réalisées par thermoformage ; ces pièces se fixent aux volets du fond pour en sortir par la découpe correspondante ; ainsi les fonds peuvent facilement s'empiler puisque les organes d'accrochage se placent les uns dans les autres dans la pile. Cela donne un empilage très peu encombrant.According to a particularly advantageous characteristic of the invention, the fastening members are hollow parts of small thickness, for example, produced by thermoforming; these parts are fixed to the bottom flaps to exit by the corresponding cut; thus the funds can easily be stacked since the hooking members are placed one inside the other in the stack. This gives a very space-saving stacking.

Dans la majorité des cas, les organes d'accrochage et les découpes sont situés au milieu du côté ou volet du couvercle et du fond.In the majority of cases, the fastening members and the cutouts are located in the middle of the side or flap of the cover and the bottom.

Dans certains cas on place un ruban ou une ficelle autour de la boîte, aussi est-il avantageux que les organes d'accrochage soient dédoublés de part et d'autre de l'axe de symétrie du côté ou qu'ils comportent une fente pour le passage de la ficelle ou du ruban, pour qu'il n'enfonce pas l'organe d'accrochage.In some cases, a ribbon or string is placed around the box, so it is advantageous for the hooking members to be split on either side of the axis of symmetry on the side or for them to have a slot for the passage of the string or ribbon, so that it does not sink the fastening member.

Lorsque l'organe d'accrochage est dédoublé, la découpe du volet du couvercle peut également être remplacée par deux découpes.When the fastening member is split, the cutout of the cover flap can also be replaced by two cutouts.

Bien qu'usuellement les boîtes pâtissières soient de forme parallélépipédique à base carrée, des formes rectangulaires sont également envisageables selon l'invention.Although the pastry boxes are usually of rectangular shape with a square base, rectangular shapes can also be envisaged according to the invention.

Enfin, l'invention permet une très grande souplesse de réalisation. Le couvercle étant séparé du fond, il peut être réalisé en une matière différente de celle du fond. Le couvercle, et en particulier la face extérieure du couvercle, peut être en une matière décorative. Le panneau du fond ou toute la surface intérieure du fond peuvent recevoir de fabrication une pellicule imperméable pour éviter que les produits éventuellement humides placés sur le fond n'imprègnent la matière constitutive du fond (par exemple du carton).Finally, the invention allows a very great flexibility of realization. The cover being separated from the bottom, it can be made of a material different from that of the bottom. The cover, and in particular the outside of the cover, can be in a decorative material. The bottom panel or the entire interior surface of the bottom can receive an impermeable film during manufacture to prevent any possibly wet products placed on the bottom from impregnating the constituent material of the bottom (for example cardboard).

Cela peut être nécessaire dans certains cas comme pour l'emballage de produits gras comme des dessous de pizzas.This may be necessary in some cases such as for packaging fatty products such as pizza toppers.

La séparation du fond et du couvercle permet également une plus grande souplesse de fabrication et de stockage. L'utilisateur peut pour un même format (c'est-à-dire une même forme de base carrée ou rectangulaire de dimensions données), disposer de fonds de hauteurs différentes pour un même couvercle ; le couvercle peut avoir une décoration uniforme identifiant le magasin, une chaîne de magasins, etc...Enfin, il convient de remarquer que l'élasticité et l'effet de ressort créés par les coins reliant les volets et qui tendent à écarter les volets, c'est-à-dire à ouvrir le fond, sont des moyens extrêmement intéressants pour garantir l'engagement des organes d'accrochage dans les découpes du couvercle.The separation of the bottom and the cover also allows greater flexibility of manufacture and storage. The user can, for the same format (that is to say the same shape of a square or rectangular base of given dimensions), have funds of different heights for the same cover; the cover may have a uniform decoration identifying the store, a chain of stores, etc. Finally, it should be noted that the elasticity and the spring effect created by the corners connecting the shutters and which tend to spread the shutters apart , that is to say to open the bottom, are extremely interesting means to guarantee the engagement of the hooking members in the cutouts of the cover.

Bien que les organes d'accrochage puissent en théorie également se fixer par exemple par collage sur la face extérieure de deux volets, cette solution n'est pas intéressante car cela ne permet pas un positionnement aussi précis des organes d'accrochage par rapport aux volets du fond et par suite des découpes des volets du couvercle. De plus, cela ne facilite pas l'empilage car les fonds seront alors empilés avec un intervalle correspondant à l'épaisseur des organes d'accrochage.Although the fastening members can in theory also be fixed for example by gluing to the external face of two flaps, this solution is not advantageous because it does not allow such precise positioning of the fastening members relative to the flaps from the bottom and as a result of the cutouts of the cover flaps. In addition, this does not facilitate stacking because the funds will then be stacked with an interval corresponding to the thickness of the fastening members.

Différents modes de réalisation et des matières ont été envisagés pour la présente invention.Different embodiments and materials have been considered for the present invention.

Dans certains cas, si le fond est réalisé en matière thermoformée, les organes d'accrochage peuvent être réalisés en même temps que le fond.In some cases, if the bottom is made of thermoformed material, the fastening members can be made at the same time as the bottom.

La présente invention sera décrite ci-après de manière plus détaillée à l'aide des dessins annexés dans lesquels :

Les volets sont reliés entre eux par des arêtes 110, 111, 112, 113 formées dans cet exemple par le collage de pattes rabattues à l'intérieur ; ces pattes, non représentées, prolongent par exemple l'un des volets et sont collées contre le volet adjacent pour former les arêtes 110, 111, 112, 113. Pour mettre le couvercle à plat, deux volets homologues sont munis de lignes de pliage 114, 115 et 116, 117 suivant la bissectrice de chaque angle.The cover 1 is formed by a panel 101 of square or rectangular shape. This panel 1 is bordered by flaps 102, 103, 104, 105. These flaps are connected to panel 101 by fold lines forming hinges 106, 107, 108, 109. The flaps are connected together by edges 110, 111 , 112, 113 formed in this example by the bonding of legs folded inside; these tabs, not shown, extend for example one of the flaps and are glued against the adjacent flap to form the edges 110, 111, 112, 113. To put the cover flat, two homologous flaps are provided with fold lines 114 , 115 and 116, 117 along the bisector of each angle.

Enfin, deux volets opposés 103, 105 sont munis de découpes 120, 121 pour recevoir un organe d'accrochage de section correspondante porté par deux volets homologues du fond comme cela sera décrit ultérieurement.Finally, two opposite flaps 103, 105 are provided with cutouts 120, 121 to receive a hooking member of corresponding section carried by two homologous flaps of the bottom as will be described later.

Le fond 2 est représenté à la figure 1B en trait plein dans une position intermédiaire, en trait plein, et dans sa position complètement dépliée, en trait interrompu.The bottom 2 is shown in FIG. 1B in solid lines in an intermediate position, in solid lines, and in its fully unfolded position, in broken lines.

Ce fond se compose d'un panneau 201 carré ou rectangulaire bordé par des volets 202, 203, 204, 205 reliés au panneau 201 par des lignes de pliage formant charnières 206, 207, 208, 209. Les volets sont reliés entre eux par des coins pliés 210, 211, 212, 213 dont la forme apparaîtra mieux à la figure 2.This bottom consists of a square or rectangular panel 201 bordered by flaps 202, 203, 204, 205 connected to panel 201 by fold lines forming hinges 206, 207, 208, 209. The flaps are connected together by folded corners 210, 211, 212, 213 whose shape will appear better in FIG. 2.

Deux volets opposés, par exemple 203, 205, sont munis de découpes 214, 215 recevant un organe d'accrochage 216 comme celui représenté en coupe à la figure 3. Ces organes d'accrochage viennent se loger dans les découpes 120, 121 du couvercle 1 lorsque celui-ci est placé par-dessus le fond.Two opposite flaps, for example 203, 205, are provided with cutouts 214, 215 receiving a hooking member 216 like that shown in section in FIG. 3. These members hooking are housed in the cutouts 120, 121 of the cover 1 when the latter is placed over the bottom.

Les découpes 214, 215 sont situées de préférence au milieu de chaque volet.The cutouts 214, 215 are preferably located in the middle of each flap.

Ces découpes peuvent également être dédoublées, c'est-à-dire remplacées par deux découpes 215A, 215B séparées par une bande de matière 215C comme cela est représenté seulement pour le volet 205. Ces découpes 215A, 215B reçoivent un organe d'accrochage unique à deux parties en saillie à travers les deux découpes 215A, 215B ou par deux pièces distinctes. Ces parties en saillie laissent entre elles une fente correspondant à la bande 215C pour le passage de la ficelle ou du ruban utilisés pour éventuellement nouer l'emballage.These cutouts can also be split, that is to say replaced by two cutouts 215A, 215B separated by a strip of material 215C as shown only for the flap 205. These cutouts 215A, 215B receive a single hooking member with two parts projecting through the two cutouts 215A, 215B or by two separate parts. These projecting parts leave between them a slot corresponding to the band 215C for the passage of the string or ribbon used to possibly tie the packaging.

La figure 3 montre la disposition du couvercle 1 et du fond 2 en position d'emboîtage et d'accrochage au niveau de l'organe d'accrochage 216 porté par le volet 203 du fond et passant par la découpe 120 du volet 103 du couvercle 1.Figure 3 shows the arrangement of the cover 1 and the bottom 2 in the nesting and hooking position at the hooking member 216 carried by the flap 203 of the bottom and passing through the cutout 120 of the flap 103 of the cover 1.

L'organe d'accrochage 216 est une pièce de section correspondant à celle des découpes 214 et 120. Cette pièce obtenue par exemple par thermoformage à partir d'une feuille de format rectangulaire (format représenté en pointillés sous la référence 217 à la figure 1B), laisse subsister des bords 218 et forme un corps 219 creux, allongé. Ce corps vient en saillie dans la découpe 120. Par le bord 217 cette pièce d'accrochage 216 est fixée au volet 203 par exemple par collage. Pour dégager l'organe d'accrochage 216 du couvercle 1, c'est-à-dire pour libérer le couvercle, il suffit d'appuyer sur le corps 219 qui apparaît à l'extérieur pour l'enfoncer en jouant sur l'élasticité à la fois du volet 203, du mouvement d'articulation élastique au niveau de l'arête formant charnière 207 et, enfin, sur le transfert d'élasticité entre les volets au niveau des coins 210, 211, 212, 213 (figure 1B). Cette transmission complexe des efforts est également l'une des raisons pourquoi il ne serait pas possible de réaliser des organes d'accrochage sur les quatre volets ou côtés du fond et du couvercle.The fastening member 216 is a piece of section corresponding to that of the cuts 214 and 120. This piece obtained for example by thermoforming from a sheet of rectangular format (format shown in dotted lines under the reference 217 in FIG. 1B ), leaves edges 218 and forms a hollow body 219, elongated. This body protrudes in the cutout 120. By the edge 217 this hooking piece 216 is fixed to the flap 203 for example by gluing. To release the fastening member 216 from the cover 1, that is to say to release the cover, it suffices to press on the body 219 which appears on the outside to push it in while playing on the elasticity both of the flap 203, of the elastic articulation movement at the hinge edge 207 and, finally, on the transfer of elasticity between the flaps at the corners 210, 211, 212, 213 (FIG. 1B) . This complex transmission of forces is also one of the reasons why it would not be possible to produce hooking members on the four flaps or sides of the bottom and of the cover.

Selon une variante, l'organe d'accrochage 216 se poursuit vers le bas jusqu'à l'articulation 207 par un prolongement 216A qui est éventuellement engagé dans une fente réalisée dans l'articulation 207 et assurant le maintien de l'organe 216 par son prolongement 216A. Cet organe 216 se met en place, d'abord par engagement de l'extrémité du prolongement 216A dans la fente puis basculement pour engager et enclipser le corps 219 dans la découpe 120.According to a variant, the fastening member 216 continues downwards to the joint 207 by an extension 216A which is possibly engaged in a slot made in the joint 207 and ensuring the maintenance of the member 216 by its extension 216A. This member 216 is put in place, first by engaging the end of the extension 216A in the slot then tilting to engage and clip the body 219 into the cutout 120.

Le couvercle 1 et le fond 2 peuvent se réaliser dans différentes matières telles que du carton plus ou moins rigide, du carton ondulé ou de la matière plastique, une matière isolante simple ou composée. La mise en forme se fait par découpage, rainage et le cas échéant thermoformage.The cover 1 and the bottom 2 can be made of different materials such as more or less rigid cardboard, corrugated cardboard or plastic, a simple or composite insulating material. The shaping is done by cutting, creasing and if necessary thermoforming.
