  Folding rectangular parallelepiped boxUSPTO Application #: 20070272699Title: Folding rectangular parallelepiped box Abstract: The upper leaf (41) of the second walls (4) is extended by a reinforcing plate (42). This plate surrounds the frame (2) and is secured to the inner face of the upper leaf (41), in such a way that when the box is in the erect position, this plate (42) presses against the associated second wall (4), while in the folded position the lower part (420) of this plate (42) is detached from the second wall (4) and forms an inverted “Y” therewith. The invention relates to a folding rectangular parallelepiped box (1) which opens at the top. The box includes a base wall (3) and a rectangular upper frame (2), together with four side walls (4, 5), two facing walls, known as the first walls (5), articulated to the base (3) or frame (2) while the other two facing walls, called the second walls (4), include two leaves (40, 41) one of which is articulated to an axis (L3) parallel to the base (3), are also articulated both to the base (3) and to the frame (2). In one embodiment, this base (3) and the second walls (4) are a single folded sheet (F2), while the axes of articulation of the walls (4) to the base and to the frame (2), and of the leaves (40, 41) to one another, are in the form of fold lines (L2, L3, L4).

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a folding rectangular parallelepiped box which opens at the top. [0003] 2. Discussion of Related Art [0004] Boxes of this type are known, made entirely of plastic, comprising a base wall and a rectangular upper frame, together with four side walls, including two facing walls, called first walls, articulated to the frame while the other two facing walls, called second walls, including two leaves articulated to one another about an axis parallel to the base and also articulated both to the base and to the frame in such a way that after pivoting the first walls inwards to bring them into a plane parallel with the base, the two leaves of the second walls can be pivoted about the axis to bring them into a position in which they are folded one on the other towards the inside of the box in a position substantially parallel to the base. [0005] It takes very little time to go from the erect position to the collapsed position, making this box particularly practical. Moreover, the fact that it is made entirely of washable plastic make it suitable for many varied uses. [0006] However, as the base, the frame, the first walls and the leaves of the second walls constitute a number of independent parts articulated to one another, the manufacture and assembly of such boxes are relatively tedious. [0007] Moreover, owing to its "all plastic" structure, the axes of articulation which consist of hinges or simple tabs may eventually break off the box if the load placed on them is too great. [0008] U.S. Pat. No. 2,755,955 also discloses a box of this kind. [0009] A reinforcing plate with dimensions substantially equal to those of the second walls is associated with the top leaf of the walls, in such a way that, when the box is in the erect position, this plate presses against the associated second wall, while in the folded position the lower part of this plate is detached from the second wall and forms an inverted "Y" therewith. [0010] This technical solution partially solves the problem of robustness of the box. [0011] However, this box, like the box described previously, comprises a number of independent parts articulated to one another. [0012] Moreover, such a box is also excessively heavy, giving rise to ergonomic problems. [0013] Lastly, documents EP-A-1 302 405, JP-A-2000/072 141 and JP 2003/300 526 disclose box structures similar to that described above, whose base and two facing faces are obtained by folding a single sheet of plastic. These structures partially solve the weight problem. However, such boxes have a major drawback relating to their lack of rigidity. SUMMARY OF THE INVENTION [0014] One object of this invention is to overcome these drawbacks by proposing a box whose structure is rationalized, in such a way as to reduce its number of parts while ensuring good robustness and excellent rigidity. [0015] Another object of this invention is to provide a lightweight box whose internal walls do not have surface irregularities that could damage the goods transported. [0016] The invention relates to a folding rectangular parallelepiped box which opens at the top, comprising a base wall and a rectangular upper frame, together with four side walls, including two facing walls, called the first walls, being articulated to the base or frame while the other two facing walls, called the second walls, include two leaves one of which is articulated to an axis parallel to the base, are also articulated both to the base and to the frame in such a way that after pivoting the first walls inwards to bring them into a plane parallel with the base, the two leaves of the second walls can be pivoted about the axis to bring them into a position in which they are folded one on the other towards the inside of the box in a position substantially parallel to the base. The base and the second walls comprise a single folded sheet of plastic or cardboard, while the axes of articulation of the walls to the base and to the frame, and of the leaves to one another, comprise fold lines. [0017] In accordance with one preferred embodiment the upper leaf of the second walls is extended by a reinforcing plate with dimensions substantially identical to those of the walls. This plate surrounds the frame and is secured to the inner face of the upper leaf, in such a way that when the box is in the erect position, this plate presses against the associated second wall, while in the folded position the lower part of this plate is detached from the second wall and forms an inverted "Y" therewith. [0018] By virtue of this feature, a single sheet is used to form the upper leaf of the second walls and the reinforcing plate, instead of parts which, in the prior art, consisted of different elements. [0019] This has an advantageous effect on the method for manufacturing the box and its cost price. [0020] Furthermore, because the axes of articulation comprise fold lines, problems of articulation hinges or tabs breaking or coming off, or constituting reliefs and surface irregularities that could damage the goods transported are minimized or avoided. [0021] Moreover, according to other advantageous and non-limiting features: [0022] the plastic comprises cellular polypropylene, in particular extruded, or solid polypropylene; Continue reading...
