panel in its curved shape.

* a background, and

* a lid.

  Such a basket is not capable of being dismantled a significant number of times. since during disassembly, there is a significant risk of deterioration of the elements and since disassembly of the basket is only possible once emptied. In addition, the parts which overlap in the basket according to this American patent are not firmly applied against each other. The assembly of this basket is also quite complicated since all the

  elements must be engaged simultaneously in their respective opening.

  The present invention relates to a basket whose assembly and disassembly is easy, including the risk of deterioration of the panel during a

disassembly are nonexistent.

  The multipurpose basket according to the invention comprises: * a substantially rectangular panel curved so that two parts of the panel overlap at least partially, said panel having a series of windows having first and second opposite straight edges parallel or not between them, of identical or different length and spaced from each other by a variable spacing or not, * at least two elements partially engaged in windows of the panel connecting together parts of the panel which overlap so as to maintain the panel in its curved shape, * possibly a background, and

* possibly a cover.

  This basket is characterized in that each of said at least two elements consists of a metal dish having: - a frame defining a passage and having interior edges turned towards said passage including a first interior edge and a second interior edge opposite said first inner edge are straight. said first and second straight interior edges extending relative to each other with a spacing corresponding to the spacing of said first and second opposite edges of the windows connected to each other by the element, a first flap attached to said frame the along the first straight inner edge 0 and having one or more edges not attached to said frame so that said first inner edge forms a pivot line of the first flap relative to the frame, and - a second flap attached to said frame along the second edge straight interior and having one or more edges not attached to said frame so that said second inner edge forms a pivot line of the second flap relative to the frame, and in that said first and second inner edges of the frame of the connecting element two windows of identical size of the panel have a length corresponding respectively to the length of the first straight edge and of the 0 second straight edge it windows on which the first and second flaps bear respectively in the vicinity of their fold line after folding

of these.

  According to one feature, the windows of the panel have straight edges which are parallel to each other and of identical length, preferably defining an opening of substantially square shape. Preferably, the flaps each have a maximum width corresponding substantially to half the length of the right edge of the frame.

  forming the pivot line of the flap considered.

  According to one embodiment, the elements consist of a metal dish 0 having a frame defining a first passage and a second passage separated from each other by a tongue extending between two edges of the frame, a first flap having a first straight edge corresponding to an edge of the first passage and along which the flap is attached to said frame and one or other edges not attached to said frame so that said first edge forms a pivot line of the first flap relative to the frame, and a second flap having a first straight edge corresponding to an edge of the first passage and along which the flap is attached to said frame or to said tongue and one or more edges not attached to said frame so that said first edge forms a pivot line of the second flap relative to the frame or to said tongue. a third flap having a first straight edge corresponding to an edge of the second passage and along which the flap is attached to said frame and one or more edges not attached to said frame so that said first edge forms a pivot line of the third flap relative to the frame, and a fourth flap having a first straight edge corresponding / 5 to an edge of the second passage and along which the flap is attached to said frame or to said tongue and one or other edges not attached to said frame so that said first edge forms a pivot line of the fourth flap relative to the frame or said tongue, said first edges of the first and second flap being parallel to each other, while said first edges of the third flap and of the fourth flap are parallel to each other , and in that the element is partially engaged, on the one hand, in two windows of the panel of identical size. And on the other hand. in two other windows of the panel of identical size or in another window of the panel and a bottom window of the same size, said first edges of the flaps having a length corresponds to the length of the parallel straight edges of the windows on which said first support respectively edges of the shutters after folding thereof, the distance between said first edges of the first and second shutters and the distance between said first edges of the third and fourth shutters corresponding to the distance between said straight edges of the windows on which the first rest respectively edges of

shutters after folding them.

  According to another embodiment, the curved panel has an outer face extending between a lower edge and an upper edge, in that in the vicinity of the upper edge and the lower edge, the panel has windows and is associated on its inner and / or outer face to one or more ferrules having at least two windows. said windows having dimensions equal to those of panel windows. Elements with two flaps or more than two flaps as defined above are partially engaged in a window of the panel and in a window of the shell to connect the shell to the panel. Preferably. one of the ferrules is secured to a tray forming the bottom of the basket. This background may have one or more perforations for

  allow the flow of liquids.

  According to a detail of an embodiment. the curved panel has an interior face, while the frames of the elements bear on said face

interior of the panel.

  The invention also relates to a kit for the production of a basket according to the invention by bending a rectangular panel. by assembling two parts of the panel by means of elements as defined

  0 in one of the preceding claims whose flaps are folded in

  windows of the panel, said kit comprising at least one rectangular panel, elements, and advantageously two ferrules. possibly a background and

possibly a cover.

  The subject of the invention is also a process for the recovery of packaging or other lost products to be recovered or recycled by means of baskets according to the invention, in which by means of a kit according to the invention, one substantially mounts instead recovery of said packaging or products one or more baskets according to the invention by bending a substantially rectangular panel and by assembling two parts of the panel by means

  0 of elements as defined in one of the preceding claims, the

  shutters are folded into panel windows. in which we collect packaging or products in the basket or baskets. in which the baskets containing the packaging or products are brought to a recycling or sorting site. in which at the recycling or sorting site we remove the packaging or products contained in the baskets. and in which the basket is disassembled by bringing the flaps of the elements in a plane position relative to the frame, so as to replace the basket in the form of a kit according to the invention. The substantially rectangular panel of the basket according to the invention is produced from a sheet of recycled metal, or of recycled synthetic material such as polyvinyl chloride, polyethylene of

  terephthalate. or laminated cardboard.

  Each clip or mounting element is for example made up of a metal flat cut by stamping in a rectangular frame which surrounds two symmetrical flaps capable of pivoting around fold lines arranged along opposite sides of the rectangular frame. The frame of the flat is intended to be applied against the edges of a rectangular or square cut in the sides of the superimposed cardboard sheets intended to be assembled. The mounting elements or clips are advantageously made

  made of a material which can be attracted by a magnet.

  The invention falls within the framework of the two European Directives organizing the obligation to take back transport packaging and the recycling of lost packaging. These directives are based on the principle that the polluter must not try to recover the waste he produces himself. The manufacturer-producer is often considered to be the polluter. It is responsible for avoiding the scattering of the packaging that it produces and / or uses. So it's up to him

  the task of collecting and / or recovering lost packaging.

  For this purpose. the invention recommends the distribution of mounting kits and the assembly of baskets by manufacturers-suppliers of products and / or packaging. This distribution takes place in the immediate vicinity of the delivery and / or distribution points of the products in question, in order to ensure the return of packaging as provided for in said European Directives. When the basket is intended to collect empty cans, the body

  cylindrical of the basket advantageously has the shape of an enlarged can.

  It is made from a sheet of aluminum, for example recycled, and advantageously bears an advertisement relating to a cold drink. The upper cover has an opening with a diameter of approximately 7 cm. If it is a question of recovering plastic bottles, an opening of approximately cm is advantageously provided in the cover. The basket is made from a sheet of advantageously recycled synthetic material, such as a sheet of polyethylene terephthalate or polyvinyl chloride. The bottom of a basket intended for the exterior can be produced from a mesh end which

  has the advantage of letting a liquid run out.

  According to an advantageous embodiment. the basket has a collection bag. this bag advantageously having a substantially cylindrical shape matching the inner wall of the basket and preferably being provided with a handle or a ring serving as a handle. This handle is for example mounted on the outer wall forming the bottom of the bag, this handle then allowing an easy emptying of the bag by simple hanging upside down or by the bottom on an endless chain comprising means or hooks to suspend the bags. The bag used is advantageously a bag woven from a vegetable material, such as hemp, linen. cotton. etc. The bag used is therefore advantageously a bag not made of plastic. The bag is advantageously recoverable, and can be cleaned. disinfected, and can possibly be reused. The color of the bags will advantageously be adapted according to the products to be introduced into the bags, for example gray-aluminum color for metallic waste, green color for glass, blue color for plastics, brown color for Tétrapak R empties. White color for swaddling clothes, gray color for household waste, etc. The bags advantageously bear indications. for example drawings, in capital letters. etc. to easily find out which product (s) are intended

  to be thrown in this or that bag.

  The mounting element or clip connecting two windows of the panel by folding the flaps forms a passage capable of receiving the end of a hook attached to a support or to a wall, so as to suspend the basket. When the element is placed on the inside of the basket, the frame advantageously serves as a support for the end of the hook and thus protects the

sign.

  The dimensions of the basket are chosen according to the number of packages or objects to be recovered. The useful volume of the baskets is determined according to the needs and the space available at the places where the lost packaging is distributed, used and / or discarded, for example the refectory

  of a school, the reception of a hospital establishment.

  It is indeed a logistics chain from the supplier-

manufacturer to consumer.

  The basket, which is delivered in kit form, reduces storage and transport costs. Due to its small size, the mounting kit is always available and close to the deliveryman of the products packaged in said packaging. The mounting kit comprises, for example, a rectangular sheet of approximately I m2, preferably laid flat, this sheet having two series of cuts along edges or edges of parts of the sheet intended to be superimposed. The volume required to transport the mounting kit is 25% less than that occupied by baskets of identical size which would be nested one inside the other. The cost of the mounting kit is low and can be easily borne by the supplier or manufacturer. In addition, the dismantling of the basket. for example to recover and recycle the collected packaging, is easy. the dismantled basket can then be returned in the form of a kit, possibly after a panel washing operation. The basket is indeed profitable because of the income provided by the advertising space and the proceeds from the sale to packaging processors to be recycled. The advertising brought to the baskets can be chosen so as to

  suit the destination of the basket perfectly.

  These and other features and details of

  the invention will appear during the following description, making reference

  in the attached drawings, which illustrate by way of nonlimiting example two forms

for carrying out the invention.

  In these drawings - Figure 1 is a perspective view of the parts forming the mounting kit of an embodiment of a basket according to the invention; - Figure 2 is an exploded perspective view of a basket for collecting beverage cans in a single family home. after assembly of the panel of the kit of Figure 1; - Figure 3 is a vertical sectional view of the fully assembled basket of Figure 2 :; - Figure 4 is a plan view of a mounting element ready for use; - Figures 5 and 6 are partial sectional views showing the placement of a mounting element to connect two windows of superimposed parts of the panel: - Figure 7 is a view of a cylindrical bag for a basket according to the invention , and Figure 8 is a view similar to that of Figure 4 of another element of

  mounting. but whose tabs were folded during its assembly.

  In these figures, the same reference signs designate elements

identical and / or analogous.

  As illustrated in FIG. 1, a multipurpose basket 1 intended for the selective collection of lost packaging with a view to recovering and / or recycling it, is produced on site, preferably at distribution points for products packaged in said packaging. by clipping a rectangular panel 2 which is bent to the dimensions of a reinforcing ferrule 3, a bottom end piece 4 and / or a cover 5. The rectangular panel 2 is produced from a sheet of recycled metal, or of recycled synthetic material such as polyvinyl chloride, polyethylene terephthalate, or

plasticized cardboard.

  The substantially rectangular panel (2) is curved so that two parts 2A, 2B of the panel overlap at least partially, said panel having a series of windows 9A, 9B having first and second edges 90.91 opposite opposite parallel to each other , of length "L"

  identical and spaced from each other by a spacing "e".

  Four elements 6 partially engaged in panel windows connect parts 2A, 2B of the panel which overlap so as to maintain the panel 2 in its curved shape. Each of said four elements consists of a metal dish having - a frame 60 defining a passage P and having interior edges 61,62,63,64 facing towards said passage including a first interior edge 62 and a second interior edge 64 opposite to said first edge interior are straight and parallel to each other, said first and second straight interior edges 62,64 l extending relative to each other with a spacing "e 1 corresponding to the spacing of said first and second edges 90,91 opposite windows 9

  linked together by element 6.

  - A first flap 11 attached to said frame 60 along the first straight inner edge 62 and having edges 11 A. 1 l B., 1 C not attached to said frame so that said first inner edge 62 forms a pivot line of the first flap 11 relative to the frame 60, and - a second flap 12 attached to said frame 60 along the second straight inner edge 64 and having edges 12A.12B, 12C not attached to said frame 1 0 so that said second inner edge 64 forms a pivot line of the

  second part in relation to frame 60.

  The edges 1 lB and 12B are rounded at their ends adjacent to the edges

1 lA, 11C and 12A, 12C.

  The said first and second internal edges 62, 64 of the frame 60 of the element 6 connecting two windows 9A, 9B of identical dimension to the panel 2 have a length "'L 1" corresponding respectively to the length "L" of the first straight edge 90 and the second straight edge 91 of the windows 9A, 9B on which the first 11 and the second flap 12 bear respectively

  vicinity of their fold line 62.64 after folding them.

  Advantageously, the frame is supported on the face of the part 2A of the panel facing the interior of the basket. while the flaps 11, 12 are folded to be engaged in the windows 9A, 9B (see FIG. 5) before being folded down on the face of the part 2B of the panel facing outwards from the basket. When folding the flaps, correct positioning of the parts of the panel which are to be covered is ensured, thanks to the fact that the flaps bear on the parallel edges of the windows 9A.9B before being folded down and thanks to the fact that the lateral edges 11 A, 1 1C, 12A, 12C limit or preferably prevent any translational movement of the element. When the flaps 11.12 are folded outwards, the dismantling of the full basket is easy, since it is sufficient, for example by means of pliers, to fold the flaps

  preferably to bring them into one or more windows 9A, 9B.

  The windows 9A.9B of the panel have straight edges which are parallel to each other and of identical length, preferably defining an opening of substantially square shape. In this case, the flaps each have a maximum width X corresponding substantially to half the length L I of the edge

  right of the frame forming the pivot line of the flap considered.

  The curved panel 2 has an outer face extending between a lower edge 2C and an upper edge 2D. In the vicinity of the upper edge 2D and of the lower edge 2C, the panel 2 has windows 10 and is associated with a ferrule 3,4 having at least two windows 30. 40, said windows 30,40 having dimensions equal to those of the windows 10 of the panel. Elements 6 such as those shown in FIG. 4 and as described above are partially engaged in a window of the panel and in a window of the shell to connect the shell to the panel. The ferrule 3 is advantageously placed inside the basket, while the ferrule 4 advantageously touches the outside face of the panel 2. The ferrule 4 is secured to a plate 41 forming the bottom of the basket. A cover 5 makes it possible to close the

basket.

  The elements 6 advantageously consist of a metal plate or a flat cut by stamping in a rectangular or square frame 60 playing the role of frame. To facilitate the folding of the flaps 11, 12 relative to the frame, one can provide a groove extending along the fold line. Preferably, a groove 66 is provided along the fold lines on each of the opposite faces of the flat element 6. According to one feature, each flap is provided on these two opposite faces with two grooves 1 10,120 located relative to the grooves 66 substantially at a distance corresponding to twice the thickness of the panel 2. The grooves 110, 120 are

parallel to the grooves 66.

  Using the basket mounting kits according to the invention, one or more baskets for the selective collection of packaging (aluminum foil, aluminum cans, plastic bottles, etc.) are substantially mounted instead of taking up said packaging or products. ). These baskets are obtained by bending a substantially rectangular panel and by assembling two parts 2A.2B of the panel 2 by means of elements 6 as defined above whose flaps 11.12 are folded in windows of the panel and folded over the outer face of the curved panel. Depending on the nature of the packaging, they are introduced into one or the other basket so as to ensure selective collection of packaging or products. Once substantially filled or at regular time intervals, the baskets containing the packaging or products are transported to a recycling or sorting site. At the recycling or sorting site, the packaging or products contained in the baskets are removed and the basket is disassembled by bringing the flaps 11, 12 of the elements in a plane position relative to the frame 60, so as to put the basket back under the form of a kit. Advantageously, the basket is disassembled to remove the packaging or products it contains. In this case, the elements 6 are advantageously made of a material making it possible to recover them from a sorting chain by means of a simple magnet. The panels, basket covers, basket bottoms, ferrules are easily recovered either by manual sorting or by a large mesh screen allowing the packaging or recovered products to pass. Once disassembled, the constituent parts of the basket can be subjected to effective cleaning, since all the faces of the constituent parts of the basket are accessible. This avoids the presence of materials or detritus or organisms in the overlapping parts of the basket, in the vicinity of the bottom, of the upper shell, etc. The substantially cylindrical body defined by the curved panel of the basket is furnished with a sign (color to indicate the type of material or packaging to be thrown in the basket), an advertising or educational message in

  relationship with the product packaged in the packaging to be recovered.

  Figure 8 shows a particular element capable of connecting two windows of part 2A with two windows of part 2B. Said element 6 consists of: * a metal dish having a frame 60 defining a first passage PlI and a second passage P2 separated from each other by a tab LA

  extending between two edges 60A, 60B of the frame 6.

  * a first flap 110 having a first straight edge 11 OA corresponding 1 o to an edge of the first passage Pl and along which the flap is attached to said frame 6 and edges 11 OB, 1 OC.1 1 OD not attached to said frame so that said first edge 11 OA forms a pivot line of the first flap relative to the frame, * of a second flap 111 having a first straight edge 11 IA 1 5 corresponding to an edge of the first passage PI and along which the flap 111 is attached to said tongue LA and edges 111 iB, 1 11 C, 111 C not attached to said frame 60 so that said first edge 111 A forms a pivot line of the second flap 111 relative to said tongue LA, * a third flap 112 having a first straight edge 112A corresponding to an edge of the second passage P2 and along which the flap 112 is attached to said frame60 and edges 112B, 112C, 112D not attached to said frame so that said first edge 112A forms a pivot line hostage of the third flap 112 relative to the frame 60, and * of a fourth flap 113 having a first straight edge corresponding to an edge of the second passage P2 and along which the flap 113 is attached to said tongue LA and edges 113B, 113C, 113D not attached to said frame 60 so that said first edge 113A forms a pivot line of the fourth

  flap relative to said tongue.

  Said first edges 1 1 OA, 111 A of the first and second flap 110, 111 are parallel to each other, while said first edges 112A, 113A of the

  third flap 112 and fourth flap 113 are parallel to each other.

  The element is partially engaged, on the one hand, in two windows of the panel of identical size. And on the other hand. in two other panel windows of the same size or in another panel window and a bottom window of the same size. Said first edges 1 1 OA. 1 11 A, I 12A, 13A of the flaps have a length corresponding to the length of the parallel straight edges of the windows on which the said first edges are supported respectively 11OA, I 1AI 12A, 1 13A of the flaps after folding thereof, the distance between said first edges 1 1 OA, 1 1 A of the first and second I0 shutters and the distance between said first edges 1 1 2A, 1 1 3A of the third and fourth shutters corresponding to the distance between said straight edges of the windows on which are supported respectively the first edges of

shutters after folding them.

  In the form shown in Figure 8, the flaps 110,111,112 and 113 undergo a pivoting along a substantially horizontal folding axis, so that said element allows to connect two distinct series of windows placed one above the other. However, according to a more advantageous form, the flaps 110, 111, 112 and 113 are pivoted along a substantially vertical folding axis or along an axis substantially parallel to

the central axis of the basket.
