Description

La présente invention est relative à une boite parallélépipédique rectangle formée d'une feuille de carton découpée et pourvue de lignes de pliage pour constituer après redressement et rabattement :

  • - un fond
  • -,couvercle
  • - une première paroi latérale réunie longitudinalement au fond
  • - une deuxième paroi latérale réunissant longitudinalement le fond et le couvercle
  • - deux parois d'extrémité, transversales aux parois susdites ainsi que des moyens de retenue des parois en position redressée fermant la boite comprenant :
  • - une troisième paroi latérale réunie longitudinalement au couvercle et recouvrant après redressement la première paroi latérale;
  • - une languette réunie à cette troisième paroi latérale engagée après pliage de 90° à l'intérieur de la boite à travers une fente prévue dans la ligne de pliage entre la première paroi latérale et le fond et
  • - deux pattes d'extrémités réunies chacune à une paroi d'extrémité transversale repliables à l'intérieur de la boite.
The present invention relates to a rectangular parallelepiped box formed from a cut cardboard sheet and provided with fold lines to constitute after straightening and folding:
  • - a fund
  • -,lid
  • - a first side wall joined longitudinally at the bottom
  • - a second side wall longitudinally joining the bottom and the cover
  • - two end walls, transverse to the above walls as well as means for retaining the walls in the upright position closing the box comprising:
  • - A third side wall joined longitudinally to the cover and covering after straightening the first side wall;
  • a tongue joined to this third side wall engaged after folding 90 ° inside the box through a slot provided in the fold line between the first side wall and the bottom, and
  • - two end tabs each joined to a foldable transverse end wall inside the box.

On connaît par le brevet français No. 1.339.781 une boite de ce genre dans laquelle l'écartement de la troisième paroi latérale de la première paroi latérale entrainant la sortie de la languette hors de la fente permettant l'ouverture de la boite par son couvercle est empêchée au moyen de deux autres languettes de blocage prévues à l'extrémité de deux autres pattes transversales articulées aux extrémités longitudinales de la troisième paroi latérale que recouvrent les parois d'extrémité lorsque les pattes d'extrémité sont engagées à l'intérieur de la boite.We know from French Patent No. 1,339,781 a box of this kind in which the spacing of the third side wall of the first side wall causing the release of the tongue out of the slot allowing the opening of the box by its cover is prevented by means of two other locking tabs provided at the end of two other transverse lugs articulated at the longitudinal ends of the third side wall which the end walls cover when the end lugs are engaged inside the box.

Outre que ces moyens de verrouillage à trois languettes et pattes transversales supplémentaires sont compliqués à réaliser et à assembler en raison de leurs dimensions réduites, ils n'assurent pas un blocage réciproque entre les languettes et les pattes d'extrémité transversales en sorte que celles-ci peuvent se dégager de la boite par une faible traction ou par une pression sur le fond ou sur le couvercle.In addition to the fact that these locking means with three additional tabs and transverse tabs are complicated to produce and assemble due to their reduced dimensions, they do not ensure mutual locking between the tabs and the transverse end tabs so that these these can be released from the box by a weak pull or by a pressure on the bottom or on the cover.

De plus, une fois la boite réalisée, elle ne peut en raison de la fragilité des languettes être redéployée et reformée en sorte qu'elle ne peut être utilisée valablement comme "brique" dans un jeu de construction.In addition, once the box is made, it cannot, because of the fragility of the tongues, be redeployed and reformed so that it cannot be validly used as a "brick" in a construction game.

La présente invention a pour but une boite qui ne présente pas ces inconvénients . Selon l'invention, en position de fermeture de la boite, la languette est maintenue par des moyens de blocage contre la face intérieure de la première paroi latérale après que cette languette ait été rabattue une seconde fois de 90° à l'intérieur de la boite, de façon à empêcher que cette languette ne sorte de la boite et permette l'ouverture de la boite par son couvercle.The object of the present invention is to provide a box which does not have these drawbacks. According to the invention, in the closed position of the box, the tongue is held by locking means against the face inside of the first side wall after this tab has been folded a second time through 90 ° inside the box, so as to prevent this tab from coming out of the box and allowing the box to be opened by its cover .

D'autres particularités et détails de l'invention apparaîtront au cours de la description d'une boite en référence aux dessins annexés au présent mémoire, qui représente à titre d'exemple seulement deux formes de réalisation de l'invention.Other features and details of the invention will become apparent during the description of a box with reference to the drawings appended to this specification, which represents by way of example only two embodiments of the invention.

  • La figure 1 est une vue en plan d'une feuille de carton après découpe et pourvue de lignes de pliage en vue de réaliser une boite parallélépipédique rectangle.Figure 1 is a plan view of a sheet of cardboard after cutting and provided with fold lines in order to produce a rectangular parallelepiped box.
  • La figure 2 est une vue en perspective de la boite partiellement arrachée.Figure 2 is a perspective view of the partially broken away box.
  • La figure 3 est une variante de la figure 1Figure 3 is a variant of Figure 1
  • La figure 4 est une vue analogue à la figure 1 en vue de réaliser une botte en forme de cube.Figure 4 is a view similar to Figure 1 for making a cube-shaped boot.

Dans ces figures les mêmes notations de références désignent des éléments identiques.In these figures the same reference notations designate identical elements.

Comme on peut le voir aux figures 1 à 3, la boite est formée à partir d'une feuille de carton ou papier fort, découpée et pourvue de lignes de pliage permettant de réaliser après redressement et rabattement des parois, une boite parallélépipédique rectangle.As can be seen in Figures 1 to 3, the box is formed from a sheet of cardboard or strong paper, cut and provided with fold lines allowing to realize after straightening and folding down of the walls, a rectangular parallelepiped box.

Les lignes de pliage définissent longitudinalement successivement une première paroi latérale 1, un fond 2, réuni longitudinalement le long d'un bord longitudinal de la première paroi latérale, une deuxième paroi latérale 3 réunie longitudinalement le long du bord opposé du fond, un couvercle 4 réuni par un bord, longitudinalement à la deuxième paroi latérale et, par son bord opposé à une troisième paroi latérale 5; une languette 6 de fermeture s'étendant sur une partie du bord longitudinal opposé de la troisième paroi latérale. Les lignes de pliage définissent latéralement, de part et d'autre du fond 2, une paroi transversale 7 et une paroi transversale 8. Chacune des parois 7 et 8 est prolongée par l'intermédiaire d'une ligne de pliage d'une patte d'extrémité 9 et 10. Ces pattes d'extrémité ont une longueur correspondant à la moitié de la longueur du fond 2.The fold lines longitudinally successively define a first side wall 1, a bottom 2, joined longitudinally along a longitudinal edge of the first side wall, a second side wall 3 joined longitudinally along the opposite edge of the bottom, a cover 4 joined by an edge, longitudinally to the second side wall and, by its edge opposite a third side wall 5; a closing tab 6 extending over part of the opposite longitudinal edge of the third side wall. The fold lines laterally define, on either side of the bottom 2, a transverse wall 7 and a transverse wall 8. Each of the walls 7 and 8 is extended by means of a fold line of a tab d 'ends 9 and 10. These end tabs have a length corresponding to half the length of the bottom 2.

La première paroi latérale 1 présente dans la ligne de pliage avec le fond 2 une fente 11 dont la longueur permet de recevoir la languette 6 lorsque les parois sont redressées et rabattues pour fermer la boite parallélépipédique. Dans cette position, la troisième paroi latérale recouvre la face extérieure de la première paroi latérale, tandis que la languette 6 est rabattue contre la face intérieure de la première paroi latérale 1 et est maintenue pressée contre celle-ci par les pattes d'extrémité repliées à l'intérieur de la boite entre la deuxième paroi latérale et cette languette. A cette fin, la hauteur de la languette 6 correspond à celle de la première paroi latérale de façon à ce que la languette soit retenue par les bords repliés des pattes 9 et 10 contre la face intérieure du couvercle.The first side wall 1 has in the fold line with the bottom 2 a slot 11 whose length allows to receive the tongue 6 when the walls are straightened and folded down to close the parallelepiped box. In this position, the third side wall covers the outside face of the first side wall, while the tongue 6 is folded against the inside face of the first side wall 1 and is kept pressed against it by the folded end tabs inside the box between the second side wall and this tab. To this end, the height of the tongue 6 corresponds to that of the first side wall so that the tongue is retained by the folded edges of the tabs 9 and 10 against the inner face of the cover.

De préférence, les parois transversales 7 et 8 sont réunies aux bords transversaux opposés du fond. Pour faciliter l'introduction de la languette 6 à travers la fente 11 et des pattes d'extrémité 9 et 10 à l'intérieur de la boite il est avantageux de biseauter les coins.Preferably, the transverse walls 7 and 8 are joined to the opposite transverse edges of the bottom. To facilitate the introduction of the tongue 6 through the slot 11 and the end tabs 9 and 10 inside the box it is advantageous to bevel the corners.

La pression exercée par les pattes d'extrémité sur la languette rabattue de 180° à travers la fente contre la face intérieure de la première paroi latérale empêche la libération intempestive de la languette et des pattes d'extrémité.The pressure exerted by the end tabs on the tongue folded 180 ° through the slot against the inner face of the first side wall prevents the untimely release of the tongue and the end legs.

Si l'on veut défaire la boite, il faut d'abord retirer les pattes d'extrémité de la botte pour libérer la languette hors de la fente et ensuite ramener les parois à plat sous la forme primitive d'une feuille découpée.If you want to undo the box, you must first remove the end tabs of the boot to release the tongue out of the slot and then bring the walls flat in the original form of a cut sheet.

La forme de réalisation de la boite représentée à la figure 3 est analogue à celle de la figure 1 sauf que l'on a prévu des pattes d'arrêt trapézoïdales 12, 13 et 14, 15 le long des bords transversaux des deuxième et troisième parois latérales 3 et 5. Lorsque ces pattes sont redressées de 90° l'une vers l'autre, vers l'intérieur de la boite dans le plan transversal du parallélépipède, elles constituent des butées pour les parois transversales lorsque les pattes d'extrémité sont engagées dans la boite.The embodiment of the box shown in Figure 3 is similar to that of Figure 1 except that there are provided trapezoidal tabs 12, 13 and 14, 15 along the transverse edges of the second and third walls lateral 3 and 5. When these legs are straightened 90 ° towards each other, towards the inside of the box in the transverse plane of the parallelepiped, they constitute stops for the transverse walls when the end legs are engaged in the box.

A la figure 4, on a représenté une feuille découpée et pourvue de lignes de pliage permettant après redressement des parois de réaliser un cube. Dans ce cas, toutes les parois ont les mêmes dimensions sauf les pattes d'extrémité dont la largeur correspond à la moitié de celle des autres parois.In Figure 4, there is shown a cut sheet and provided with fold lines allowing after straightening the walls to make a cube. In this case, all the walls have the same dimensions except the end tabs, the width of which corresponds to half that of the other walls.

Il est évident que l'invention n'est pas exclusivement limitée aux formes d'ex"cution représentées et que bien des modifications peuvent être apportées dans la forme, la disposition et la constitution de certains des éléments intervenant dans sa réalisation, à condition que ces modifications ne soient pas en contradiction avec chacune des revendications suivantes.It is obvious that the invention is not exclusively limited to the forms of execution represented and that many modifications can be made in the form, the arrangement and the constitution of some of the elements involved in its realization, provided that these modifications are not in contradiction with each of the following claims.
