Description

Les boites pliantes en carton ou matière mince semi rigide similaire, matière plastique par exemple sont bien connues.Folding boxes made of cardboard or similar semi-rigid thin material, plastic for example, are well known.

Avant l'usage, elles se présentent chez le commerçant utilisateur, sous une forme plate de faible volume, grâce au repliement de la matière dont elles sont constituées.Before use, they come to the user trader, in a flat form of low volume, thanks to the folding of the material of which they are made.

Cependant, ces boîtes, très utilisées par exemple par les pâtissiers, n'ont aucune stabilité de forme quand elles sont dépliées et leur aspect, peu élégant, ne convient pas aux commerces de luxe : parfums, cosmétiques, bijouterie fantaisie, etc... Dans ces commerces où l'esthétique joue un rôle important on est conduit à utiliser des boîtes non pliantes dites "boîte boutique" de forme parallélépipédique rectangle, ayant un volume suffisant pour contenir divers objets ou produits et qui se prêtent à recevoir des décorations variées. Mais ces boîtes ont l'inconvénient qu'au stockage elles occupent un volume important. Par exemple pour la hauteur habituelle d'environ 8 cm, 30 boîtes vides empilées vont occuper une hauteur de 2,40 m, de sorte qu'un stockage important est très encombrant dans un magasin où l'on ne dispose pas de beaucoup de place.However, these boxes, widely used for example by pastry cooks, have no stability of shape when they are unfolded and their appearance, not very elegant, is not suitable for luxury shops: perfumes, cosmetics, costume jewelry, etc. In these businesses where aesthetics play an important role, we are led to use non-folding boxes called "boutique boxes" of rectangular parallelepiped shape, having a sufficient volume to contain various objects or products and which lend themselves to receiving various decorations. But these boxes have the disadvantage that in storage they occupy a large volume. For example, for the usual height of around 8 cm, 30 empty stacked boxes will occupy a height of 2.40 m, so that a large amount of storage is very cumbersome in a store where there is not much space. .

Le dispositif de boîte qui fait l'objet de l'invention permet, grâce à un pliage approprié de ses parties constitutives, de réduire de façon très importante, par exemple des deux tiers le volume de stockage, tout en fournissant pour l'emploi, des boîtes élégantes, ayant les formes stables des "boîtes boutiques".The box device which is the subject of the invention makes it possible, thanks to an appropriate folding of its constituent parts, to reduce very significantly, for example by two thirds the storage volume, while providing for use, elegant boxes, with the stable forms of "boutique boxes".

Ce dispositif se caractérise en ce que le carton ou autre matière constituant le corps de boîte, qui est muni sur au moins deux côtés opposés, des lignes de pliage nécessaires pour le repliement à plat, est combiné avec un raidisseur, adapté pour se replier également à plat sur le corps de boîte plié et ayant un contour correspondant à celui du fond de ce corps, pour venir épouser ce fond quand il est déplié dans le corps de boîte.This device is characterized in that the cardboard or other material constituting the box body, which is provided on at least two opposite sides, with the fold lines necessary for folding flat, is combined with a stiffener, suitable for also folding flat on the folded box body and having a contour corresponding to that of the bottom of this body, to come to marry this bottom when it is unfolded in the box body.

De préférence ce raidisseur est formé d'une feuille épaisse de même contour que celui du fond de la boîte et peut être avantageusement constitué par plusieurs panneaux articulés entre eux.Preferably this stiffener is formed of a thick sheet of the same contour as that of the bottom of the box and can advantageously be constituted by several panels hinged together.

De préférence encore, ce raidisseur est articulé, sur les bords supérieurs de deux côtés opposés du corps de boîte, de manière à venir doubler et renforcer ces deux côtés en même temps que le fond.More preferably, this stiffener is articulated, on the upper edges of two opposite sides of the box body, so as to come and double and reinforce these two sides at the same time as the bottom.

Le mieux est de prévoir cette articulation sur les deux côtés opposés où sont marquées les lignes de pliage à plat du corps de boîte, ce qui est favorable au raidissement de ces deux côtés, après dépliage.It is best to provide this articulation on the two opposite sides where the flat fold lines of the box body are marked, which is favorable to the stiffening of these two sides, after unfolding.

La description qui va suivre en regard du dessin annexé, donné à titre d'exemple non limitatif, fera bien comprendre comment l'invention peut être réalisée, les particularités qui ressortent tant du dessin que du texte faisant, bien entendu, partie de ladite invention.

  • la figure 1 est une vue en perspective montrant la boîte à l'état plié et son couvercle à emboîtement
  • les figures 2, 3 et 4 illustrent de même en perspective trois phases successives du dépliement de la boîte
  • la figure 5 est une coupe longitudinale du corps de boîte déplié,
  • la figure 6 est une vue de détail à plus grande échelle.
The description which follows with reference to the appended drawing, given by way of nonlimiting example, will make it clear how the invention can be implemented, the features which emerge both from the drawing and from the text which, of course, forms part of the said invention. .
  • Figure 1 is a perspective view showing the box in the folded state and its interlocking cover
  • Figures 2, 3 and 4 likewise illustrate in perspective three successive phases of the unfolding of the box
  • FIG. 5 is a longitudinal section of the unfolded box body,
  • Figure 6 is a detail view on a larger scale.

On voit sur la figure 1, d'une part, le couvercle A, du type à emboîtement, qui peut être en carton rigide, et porter des décorations variées et, d'autre part, le corps de boîte B à l'état plié.We see in Figure 1, on the one hand, the cover A, of the interlocking type, which can be rigid cardboard, and carry various decorations and, on the other hand, the box body B in the folded state .

Deux des côtés opposés C1 C2 du corps de boîte, qui a une forme rectangulaire, sont munis chacun de lignes obliques de pliage a b, a' b', qui ne sont pas concourantes mais laissent entre leurs extrémités supérieures un petit segment de droite tel que b b'. Les quatre côtés du corps de boîte sont eux-mêmes reliés au fond par des lignes de pli ce qui permet, comme on le comprend, de replier à plat le corps de boîte dans l'état que montre la figure 1.Two of the opposite sides C1 C2 of the box body, which has a rectangular shape, are each provided with oblique fold lines ab, a 'b', which are not concurrent but leave between their upper ends a small line segment such as b b '. The four sides of the box body are themselves connected at the bottom by fold lines which allows, as we understand, to fold flat the box body in the state shown in Figure 1.

A ce corps de boîte est associé un raidisseur constitué par une feuille rigide qui est munie de lignes de pli parallèles telles que d, e, f, g. Le raidisseur comporte ainsi un certain nombre de panneaux articulés 1, 2, 3, 4, 5 qui, dans l'état replié que montre la figure 1, viennent se placer à plat les uns sur les autres, l'ensemble de ces panneaux étant en outre tel que lorsqu'ils sont placés en prolongement les uns des autres dans un même plan, ils constituent un rectangle qui peut coïncider avec le rectangle constituant le contour du fond de la boîte (voir figures 3 et 4).(Sur la figure 1 le raidisseur paraît plus large que le corps de boîte parce que le corps n'est pas encore déplié à sa forme finale).With this box body is associated a stiffener constituted by a rigid sheet which is provided with parallel fold lines such as d, e, f, g. The stiffener thus comprises a certain number of articulated panels 1, 2, 3, 4, 5 which, in the folded state shown in FIG. 1, are placed flat on top of each other, all of these panels being further such that when they are placed as an extension of each other in the same plane, they constitute a rectangle which can coincide with the rectangle constituting the outline of the bottom of the box (see FIGS. 3 and 4). 1 the stiffener seems wider than the box body because the body is not yet unfolded to its final shape).

En outre, le raidisseur est attenant par ses panneaux extrêmes 1 et 5, à deux côtés opposés de la boîte, cette réunion étant réalisée par une articulation, par exemple selon la ligne b, b', tracée en pointillés sur la figure 2. Cette articulation peut être réalisée, par exemple, comme le montre la figure 6, au moyen d'une feuille de papier fort collée respectivement sur un côté de la boîte et sur le panneau attenant 1 ou 5 du raidisseur.In addition, the stiffener is attached by its end panels 1 and 5, to two opposite sides of the box, this meeting being carried out by an articulation, for example along the line b, b ', drawn in dotted lines in FIG. 2. This articulation can be achieved, for example, as shown in Figure 6, by means of a strong sheet of paper glued respectively on one side of the box and on the adjoining panel 1 or 5 of the stiffener.

Il ressort de cette description que pour faire passer le corps de boîte de son état plié, que montre la figure 1, à l'état prêt à l'usage, représenté figure 4, on commence par déplier le raidisseur et le corps de boîte pour placer l'ensemble dans la position que représente la figure 2, puis en écartant les deux côtés de la boîte qui sont perpendiculaires aux lignes de pliage du raidisseur, on engage celui-ci dans la boîte, comme le montre la figure 3. On termine cet engagement de manière que le raidisseur vienne bien épouser et doubler le fond de la boîte, tandis que, par le jeu des deux articulations d'attache telles que b, les deux panneaux extrêmes 1 et 5 du raidisseur sont plaqués contre les deux côtés C1 et C2 du corps de boîte sur lesquels ces panneaux sont articulés et qui comportent les lignes de pliage a b, a' b' du corps de boîte.It emerges from this description that in order to pass the box body from its folded state, which is shown in FIG. 1, in the ready-to-use state, represented in FIG. 4, one begins by unfolding the stiffener and the box body for place the assembly in the position shown in Figure 2, then by moving the two sides of the box which are perpendicular to the fold lines of the stiffener, we engage it in the box, as shown in Figure 3. We finish this engagement so that the stiffener comes to marry and double the bottom of the box, while, by the play of the two attachment joints such as b, the two panels extremes 1 and 5 of the stiffener are pressed against the two sides C1 and C2 of the box body on which these panels are articulated and which comprise the fold lines ab, a 'b' of the box body.

On obtient de la sorte un corps de boîte ayant une bonne stabilité de forme et qui est propre à recevoir le couvercle à emboîtement A, de hauteur nettement plus petite.In this way a box body is obtained having good shape stability and which is suitable for receiving the interlocking cover A, of significantly smaller height.

On peut prévoir sur chacun des grands côtés du raidisseur une petite saillie 3a s'engageant dans une fente 3b correspondante du corps de boîte quand le raidisseur déployé est en place, afin de maintenir ce raidisseur.One can provide on each of the long sides of the stiffener a small projection 3a engaging in a corresponding slot 3b of the box body when the deployed stiffener is in place, in order to maintain this stiffener.

L'un des résultats que procure le dispositif décrit est, comme on l'a dit, une très forte réduction du volume de stockage.One of the results of the device described is, as has been said, a very large reduction in the storage volume.

En effet, à l'état plié le corps de boîte et son raidisseur occupent une hauteur inférieure à la hauteur du couvercle, et comme celle-ci est généralement du tiers environ de la boîte, on voit que le système permet de réduire des deux tiers le volume occupé lors du stockage, pour lequel le corps de boîte plié peut être complètement recouvert par le couvercle.In fact, in the folded state, the box body and its stiffener occupy a height less than the height of the cover, and since the latter is generally about a third of the box, it can be seen that the system makes it possible to reduce by two thirds the volume occupied during storage, for which the folded box body can be completely covered by the cover.

Il y a lieu de noter que dans la description précédente, les mots "articulation" ou "articulé" doivent être entendus comme se rapportant soit à une simple ligne où la matière est amincie comme on peut le faire par exemple avec une molette pour permettre un pliage soit à un assemblage de deux plans au moyen de bandes de papier fort collées, comme sur la figure 6, soit à tout moyen équivalent.It should be noted that in the preceding description, the words "articulation" or "articulated" must be understood as referring either to a single line where the material is thinned as can be done for example with a wheel to allow a folding either to an assembly of two planes by means of strips of strongly glued paper, as in FIG. 6, or by any equivalent means.
