A bag made of plastic material is clamped at its bottom between the assembled parts of the outer flaps 4.

Description

New folding box-type packaging
The present invention relates to alternative embodiments of the folding package of the type of pallet boxes described in the main patent.

 It will be recalled that the subject of the invention is a box pallet of the type comprising a corrugated cardboard container or the like, of rectangular cross-section, whose external part of the bottom comprises two adjoining flaps by a folding line having two opposite parallel walls, on each of which is fixed a half-pallet of wood or the like, this box-pallet being characterized in that each of the walls to which are not adjacent the shutters carrying the half-pallets is divided into two equal parts by a fold line parallel to vertical edges of the container, and in that the flaps carrying the half-palettes are joined by at least one cardboard element or the like hinge, which is fixed on said flaps and which comprises a fold line disposed along the connection plane of said half-ribs. pallets.

 In such a box-pallet, it is possible, because of the vertical fold lines of the walls of the container not attached to the flaps carrying the half-pallets, to fold accordion Zen "of these walls of the container to fold it flat, with the shutters bearing the half-pallets arranged in the extension of the side walls to which they are attached.

 Conversely, it is sufficient to separate from one another the walls to which the shutters bearing the half-pallets are adjacent, by exerting a traction on these walls or on these half-pallets, so that the box-pallet is put in place. it itself in shape, the flaps carrying the half-pallets straightening perpendicular to the adjoining walls, because of the hinge element that joins them.

 It is therefore possible for the manufacturer to deliver the folded pallet boxes to the users and to store them in this way, occupying only a very small volume, in order to shape them in a simple way, without use any accessory whatsoever for their assembly or during their use.

 The present invention aims to propose a variant of the packaging according to the main patent, in which a plastic bag, integral with the corrugated container and intended to receive the contents of the box-pallet, can be delivered to the users assembled with the container and with the half-pallets.

 It is known that pallet boxes are frequently used to condition bulk particulates, such as granular or other polymers. The volume of packaged materials can be very large and their weight often exceeds one ton. In order to facilitate their packaging, these materials are generally housed in a polyethylene bag or the like inside the box pallet.

 Plastic materials, however, do not adhere well to corrugated cardboard, and it is feared that the bags stuck inside the container may become detached from the container when the pallet box according to the main patent is folded flat. to be delivered to other users, then volume by them.

The present invention aims to remedy this drawback by proposing a box-pallet according to the main patent, in which the outer flaps of the bottom of the container are no longer joined by a hinge element, but are assembled so as to form themselves a hinge pinching between them the bottom of a plastic bag
For this purpose, the invention relates to a variant of the pallet box according to claim 1 of the main patent, characterized in that the outer flaps of the bottom of the container are assembled together so as to form a dihedral edge parallel to folding lines by which these flaps are connected to the walls to which they are attached, and encasing the distance separating the edge of the dihedron from said folding lines is equal to half the distance separating said walls after putting in volume of the pallet box .

 The dihedron formed by said flaps thus constitutes a hinge allowing the flat bottom of the container to be folded between the half-pallets on which these flaps are fixed, without it being necessary to use the additional element forming a hinge provided for in the main patent. .

 In a particularly advantageous embodiment of the invention, a plastic bag, intended to double inside the container, can be clamped by its bottom between the assembled parts of said flaps, thus being secured to them.

 The outer flaps may be assembled by any means known in the art, but they will preferably be assembled by gluing, if the bottom of a plastic bag must be clamped between them, so as not to weaken this bag. Because of this method of assembling the bag -or the * bag, as is said in the art- and the container, the risk of accidental desolidarization of these elements are virtually negligible.

 The shutters may be assembled in a strip, in the vicinity of their edge parallel to their line of connection to the adjoining wall, and the assembled parts of said flaps may also be delimited along the edge of said dihedron by folding lines parallel to these connecting lines, so that after setting volume of the pallet box, the assembled portion of said flaps can be clamped between the half-pallets.

Of course, the container made in accordance with the present invention, with or without a plastic bag, is also an object of the invention.
The outer flaps of the bottom may or may not be doubled inside internal flaps adjacent to the other walls and having folding lines parallel to the vertical edges of the container, in the extension of the fold lines of the walls to which these flaps are adjacent, as described in the main patent. In the case of a plastic bag is secured to the bottom of the container, these internal flaps should be small, if they exist, to allow the positioning of the bag in the mounted position of the box pallet.

Alternatively, a slot may be formed in the middle part of these flaps, perpendicular to the adjoining walls to allow passage to this bag.

The accompanying drawings, which are not limiting in nature, illustrate various embodiments of the invention. On these drawings:
FIG. 1 is a perspective view of a first embodiment of the mounted pallet box, ready for use;
Figure 2 illustrates the folding of the corrugated container of this pallet box;
Figure 3 is a perspective view of the container of another box pallet according to the invention.

 The corrugated cardboard containers of the pallet boxes shown in the drawings are normally equipped with an internal plastic bag, but for the sake of clarity, this bag has not been shown in the drawings.

 The pallet box of FIG. 1 is of a type known per se, comprising a container 1 of corrugated cardboard, in the form of a rectangular parallelepiped, resting by its base on a wooden pallet or the like, consisting of two half-pallets 2 .

Container 1 has t
- On the one hand, two longitudinal walls 3, at the base of which are articulated by a fold line two flaps 4, which constitute the outer portion of the bottom of the container, and on which are fixed, by gluing, stapling or the like, the half pallets 2 t
on the other hand, two transverse walls 5, at the base of which are articulated by a fold line two flaps 6, which, after mounting the pallet box, are folded inside the container against the flaps 4, to constitute the inner part of the bottom.

 According to the invention, the flaps 4 are assembled by gluing, along a strip 8, in the vicinity of their edge parallel to their line of connection to the wall 3, so as to form a ridge dihedron parallel to this connecting line. , the band 8 being intended to be housed between the half-pallets 2, being clamped between them, after setting volume of the box pallet. As can be seen clearly in FIG. 2, the dihedron formed by the shutters 4 constitutes a hinge of articulation between the walls 3 and allows the flat folding of the container 1 between the half-pallets 2, the transverse walls 5 being simultaneously folded in accordion around a fold line 9, as described in the main patent.The distance between the edge of the dihedral formed by the flaps 4 of the connecting line of these flaps to the walls 3 is equal to half the distance between the walls 3 after placing the container 1 in volume, so that the flaps 4 thus constitute the bottom of the mounted container.

 A plastic bag (not shown), intended to receive the articles or materials housed in the container 1 may be clamped between the assembled parts of the flaps 4, thus being perfectly integral with the container, with which it can be delivered pre-assembled users. In this case, so that the bag can be unfolded easily inside the container 1, after setting volume of the latter, the inner flaps 6 adjacent the transverse walls 5 comprise a slot 10, in their middle part, perpendicular to the walls 5, to deliver passage audit bag.

 Alternatively, the walls 5 may be free of internal flaps or include flaps 11 of very small dimensions not forming an obstacle to the plastic bag, as shown in Figure 3.

 The embodiments of the pallet box according to the main patent which have just been described therefore have great manufacturing and volume-building advantages, particularly in the case where the container of this box must be equipped with an internal bag. plastic, which is in solidarity.
