Description

NEW FOLDABLE PACKAGING OF THE CASE TYPE
PALLETS, COMPRISING A CONTAINER IN THE FORM OF A RIGHT PRISM
A OCTAGONAL SECTION.

 The present invention relates to a new folding packaging of the pallet box type, comprising a container in the form of a straight prism with an octagonal section, which has a plane of symmetry.

 It is known that lton designates by the term box-pallet packaging comprising a cardboard packaging, corrugated cardboard or the like, the bottom of which is attached to a handling pallet, made of wood or plastic, intended to facilitate their movement.

 The use of such pallet boxes is more and more widespread, because they are easy to manufacture, of moderate cost and can have large volumes, the pallet with which they are provided allowing easy handling using transport or lift carts.

 The most used pallet boxes include a container in the shape of a rectangular parallelepiped, the bottom of which, consisting of flaps adjoining the side walls, is fixed to the pallet.

 In order to facilitate storage before use in a small volume of such pallet boxes with rectangular cross section, it has been proposed to fold the packaging body flat on the pallet, but pallet boxes of this type generally require, after assembly, the use of vertical wooden beams, called "candles" in the art, to ensure them a satisfactory hold, and this increases their manufacturing cost and complicates the assembly operations.

 It has also been proposed (see French patent NO 2 054 841) to equip the container base with two half-pallets fixed, respectively, on the flaps forming the external part of the bottom and adjoining two opposite side walls, which makes it possible to fold the flat container with the walls applied against each other, as well as the flaps forming the bottom, and with the half-pallets arranged on either side of the flattened packaging, outside of it .

 The Applicant has also proposed, in its French patent application NO 2 592 365, a pallet box- of the type comprising a corrugated cardboard container or the like, with rectangular cross section, the external part of the bottom of which comprises two adjoining flaps by a folding line with two opposite parallel walls and on each of which is fixed a wooden half-pallet or the like, each of the walls to which the flaps carrying the half-pallets are not contiguous being divided into two equal parts by a parallel folding line at the vertical edges of the container, while the flaps carrying the half-pallets are joined by at least one element of cardboard or the like forming a hinge, which is fixed on said flaps and which comprises a fold line arranged along the connection plane of said half -palettes.

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

 Conversely, it suffices to separate from one another the walls to which the flaps carrying the half-pallets are attached, by exerting traction on these walls or on these half-pallets, so that the pallet box is 'itself shaped, the flaps carrying the half-pallets straightening perpendicular to the adjoining walls, due to ltélément hinge which joins them.

 It is therefore possible for the manufacturer to deliver the folded pallet boxes to the users and for them to store them thus, occupying only a very small volume, in order to shape them in a simple manner, without use any accessory whatsoever for mounting or when using them.

Finally, based on the same general principle, the
The Applicant has proposed, in its French patent application NO 2 598 684, a pallet box of the type comprising a container made of a semi-rigid material, which comprises a packaging body in the form of a straight prism having a plane of symmetry, the edges are formed by fold lines and whose cross section is a polygon with more than four sides, two of the walls of said packaging body being parallel to said plane of symmetry; a bottom secured, on the one hand, to this packaging body, so as to close it at one end, and, on the other hand, to a handling pallet; optionally, a cover intended to close off said body at the end opposite to said bottom, this pallet box being characterized in that, in order to be able to fold it flat before its final volume setting, the bottom is integral only with parallel walls of the body and is divided into two equal parts by a fold line parallel to these walls and arranged in the plane of symmetry, the fold line being arranged in such a way that it joins together, after the pallet box has been placed in volume, two opposite edges of the body, or an edge and a fold line parallel to an opposite wall, or two fold lines parallel to the edges of two opposite walls, and in that said pallet consists of two integral half-pallets respectively of said equal parts of said bottom.

 As described in this patent application, the container body can have, for example, a pentagonal, hexagonal or octagonal section.

 It is thus possible to deliver to the user the pallet box folded flat, with the two parts of the bottom applied one against the other, as well as the walls to which they are contiguous and lws contiguous walls, the half pallets being themselves applied flat outside said bottom portions. To put the pallet box in volume, the user only has to bring the two half-pallets in the extension of one another, thus simultaneously bringing the two bottom halves in the same plane and straightening the packaging body perpendicular to the bottom, without having to use templates, as in the prior art, and without immobilizing several people for this work for a fairly long period.

 The present invention relates to a pallet box of the latter type, the body, packaging or container of which also has a polygonal section having a plane of symmetry and the support pallet of which is similarly constituted by two articulated half-pallets. between them, which can be delivered to the user independently of the packaging body, to then be fixed on this body, the pallet box thus produced then being suitable for flat folding of the packaging body equipped with half-pallets .

 The invention more specifically aims to provide a pallet box of this type, the mounting of the packaging body on the half-pallets can be performed by the user more easily than according to patent application NO 2 598 684, which can then be folded flat easily and which has excellent mechanical strength, in particular for packaging bulk products, such as plastic particles.

To this end, the subject of the invention is a box pallet comprising a container made of a semi-rigid material, which comprises: a packaging body in the form of a straight prism with an octagonal section having a plane of symmetry, the edges of which are formed by lines folding and whose cross section is a polygon with more than four sides, two of the walls of said packaging body being parallel to said plane of symmetry; a bottom secured, on the one hand, to this packaging body, so as to close it at one end, and, on the other hand, to a handling pallet, which may be a pallet in one piece or still made up of two half-pallets arranged symmetrically with respect to the plane of symmetry of the packaging body;
this pallet box being characterized in that
- Said bottom comprises two first adjoining flaps each, on the one hand, by a fold line, at the base of two parallel walls of the packaging body arranged symmetrically with respect to the plane of symmetry, on the other hand, by the intermediate a triangular tongue articulated by a fold line on said first flaps, at the base of the two adjacent walls of each of said parallel walls, said triangular tongue being itself articulated by a fold line on said adjacent walls and being such that in the assembled position of the packaging body, it comes to bear against the adjoining flap, perpendicular to the walls of said body by projecting outside of it,
- Optionally, two second flaps are attached respectively by a fold line at the base of the last two walls of the packaging body arranged perpendicular to the plane of symmetry, these second flaps being applied, in the assembled position, against the internal face of the first flaps facing inside the packaging body
- Said last walls perpendicular to the plane of symmetry are divided along this plane by a fold line parallel to the edges of the body and extend in the same plane along the entire length of said second flaps to allow folding of the packaging body , whether or not integral with half-pallets
each of said first flaps is secured, respectively, by its external face, to the pallet or to one of said half-pallets.

 The first flaps can be made integral with one another, for example by means of tongues, assembled for example along the plane of symmetry of the packaging body.

 These flaps can be glued, nailed or stapled on the half-pallets, but, advantageously, it is the triangular tabs which, in the assembled position, are arranged outside the body, which will be fixed by nailing on the half-pallets. pallets. The packaging bodies being delivered flat to the users, they will very easily put them in volume and, then, will only have to fix the triangular tabs on the half-pallets.

 To facilitate flat folding of the packaging body and its volume, the edges of the packaging body may advantageously be extended by folding lines through the first or second adjoining flaps, in a plane perpendicular to these walls.

 The first and second flaps and the walls to which they are attached may come from a single blank of cardboard or corrugated cardboard. Given the large dimensions of such pallet boxes, in particular when they are intended for packaging bulk materials whose mass can reach one tonne per packaging, it may however be advantageous to produce the packaging body in two separate parts. , the bottom part then comprising a half-body with very reduced height walls, the walls of which are directly adjacent to the first and second flaps and which are glued or fixed by stapling against the corresponding walls of the real packaging body.

 These two embodiments of the invention will be described below in detail, with reference to the accompanying drawings, which are not intended to be limiting.

On these drawings
Figure 1 is an exploded perspective view of a first embodiment of the pallet box according to the invention, in which the body of the package and the bottom constitute two separate parts which are assembled together
FIGS. 2a and 2b are plan views of the corrugated cardboard blanks from which the packaging body and the bottom of this first embodiment originate.
Figure 3 is an exploded perspective view of a second embodiment of the invention, where the packaging body and the bottom part form a single unit from the same blank; and
Figure 4 is a plan view of the corrugated cardboard blank from which the container of this second embodiment is derived.

The pallet box shown in Figures 1, 2a and 2b, includes
a packaging body C, made of a semi-rigid material such as corrugated cardboard, in the form of a straight prism with an octagonal section, symmetrical, open at its two ends and whose edges are formed by fold lines
- a bottom part F, of hexagonal shape substantially identical to the cross section of the body
J and intended to close it at one of the ends,
- two half-pallets P secured to the bottom part and hinged together by a hinge. The half pallets can also be replaced by a single pallet.

 The body C and the bottom F have a plane of symmetry passing through the joint plane of the half-pallets.

 A cover (not shown) can cover the upper end of the body.

According to the invention, the bottom part comprises eight low side walls, 1, 2, 3, 4, 5, 6, 7 and 8, intended to be glued to the outside of the corresponding walls I, II, III , IV, V, VI, VII and
Body VIII.

 At the base of the two opposite walls 4 and 8 adjoining by a fold line, first flaps 9 and 10 intended to form the outer part of the bottom and to be assembled together by a tongue 11, which can be pinched between the two half-pallets in their joint plane or be packed between the bottom and the half-pallets under the weight of the packaged materials.

 The walls 1 and 8 are assembled by gluing a tongue 12 and a flap 10a adjoining the tongue 12 is itself made integral with the flap 10 by gluing a tongue 13, the flap formed by the meeting of the flaps 10 and lOa having the same dimensions as part 9.

 On the walls 2 and 6 are articulated, by a fold line, second flaps 14 and 15, intended, in the assembled position, to be applied inside the packaging against the internal part of the flaps 9 and 10 .

 The flaps 9 and 10 are adjoining, by means of a triangular tongue, respectively 16 and 17, to the adjacent walls, respectively 3 and 5, and i and 7.

Each triangular tongue is articulated by a fold line at the base of the associated wall and on the corresponding flap by a second fold line arranged obliquely to the previous one such that in the mounted position (see FIG. 1), the tongues 16 and 17 protrude flat outside the packaging and are applied against the adjoining flap 9 or 10, to form a bellows that can be easily nailed or stapled on the half-pallets.

 The packaging body will be delivered pre-glued on the bottom part to the user. For this purpose, a fold line arranged in the plane of symmetry will divide the walls II and VI of the packaging body perpendicular to the plane of symmetry, the similar walls 2 and 6 of the bottom part and the flaps 14 and 15 adjoining these last walls.

 It will be noted that, similarly, the edges separating the walls 1 to 8 of the bottom part are extended on the adjoining flaps by fold lines, in order to facilitate the flattening and the bottom volume setting, of this part, when attached to the packaging body. The half-pallets can be easily fixed for use on the bottom part and the packaging thus finished despite its large dimensions and large volume, can be folded and stored before use.

 In the case of the embodiment of FIGS. 3 and 4, the packaging body C-1 and the part of the bottom form a one-piece assembly resulting from a single blank of cardboard which is shown in FIG. 4.

 All the parts of this assembly have already been described with reference to FIG. 2b, the walls 1 'to 8' being simply much higher than the corresponding walls 1 to 8 of the bottom part, to form the walls of the body. packaging itself.

 The invention therefore provides in the art a new packaging of the pallet box type, intended in particular for packaging bulk materials, the container of which can be delivered flat to the users, can be easily mounted by them and can even then be stored flat before use.
