Basket and kit for a basket for the return of disposable packaging

The present invention relates to a multipurpose basket that is easy to assemble or disassemble and to a kit for the manufacture of such a basket for the collection of disposable packaging or other disposable products by installing multipurpose baskets for the selective collection of disposable packaging at numerous locations, preferably at the distribution points of products packaged in packaging that can be recovered or recycled.

The selective disposal of waste is designed to facilitate the sorting of enormous quantities of waste collected by municipal services for household waste disposal. The waste comes mainly from private homes, homes, schools, community centers, hospitals, sports centers, subway stations and public places. In order to encourage the uptake of disposable packaging and to facilitate the selective sorting of waste, the present invention proposes to install waste sorting units in numerous places, for example near drinks vending machines, at the entrance to shops to recover used products or objects (batteries), in bathrooms to recover dirty diapers, in kitchens to recover drinks bottles and/or plastic bottles, in hospitals to

To recover surgical gloves, syringes, etc., for example in homes, schools, hospitals, sports centres, subway stations, installing reusable multi-purpose baskets that are easily replaceable to give them a constantly new and/or impeccable appearance.

From the document US-5372269 a multi-purpose basket is known, consisting of:

a rectangular plate which is curved such that two parts of the plate at least partially overlap each other, said plate having a series of windows having a first and a second straight edge which are opposite each other, parallel to each other and spaced apart from each other, said plate being provided along a first edge with elements which partially engage in windows located along the edge of the plate which is opposite the first edge, said elements connecting between them parts of the plate which overlap each other so that the plate is maintained in its curved shape,

a floor and
a lid.

Such a basket is not suitable for being dismantled numerous times, as there is a high risk of damaging the elements during dismantling

and because the basket can only be dismantled when it is empty. Furthermore, the overlapping parts in the basket according to the American patent are not pressed firmly against each other. The assembly of this basket is also relatively complicated because all elements have to engage in their respective openings at the same time.

The present invention relates to a basket which is easy to assemble and disassemble and which does not involve any risk of damaging the plate during disassembly.

The multi-purpose basket according to the invention comprises:

a substantially rectangular panel curved so that two parts of the panel at least partially overlap each other, the panel having a series of windows having first and second straight edges which are opposite each other, parallel or not, of equal length or not, and spaced apart from each other by a variable distance or not;

at least two elements which partially engage in windows of the panel and connect between them parts of the panel which overlap so that the panel is held in its curved shape,

possibly a floor and

possibly a lid.

This basket is characterized in that each of the at least two elements is formed from a metallic surface consisting of:

a frame defining a passageway and having inner edges facing said passageway, of which a first inner edge and a second inner edge opposite said first inner edge are straight, said first and second straight inner edges extending from one another by a distance corresponding to the distance of the first and second opposite edges of the windows connected to one another by said element,

a flap connected to the frame along the first straight inner edge and having an edge or edges not attached to the frame so that the first inner edge forms a pivot line for the first flap with respect to the frame, and

a second flap connected to the frame along the second inner edge and having an edge or edges not attached to the frame so that the second inner edge forms a pivot line for the second flap with respect to the frame, and

that the first and second inner edges of the frame of the element connecting two windows of the same size of the panel have a length equal to the length of the first

straight edge or the second straight edge of the windows on which the first or the second flap rests near their fold line after it has been folded over.

According to a particular feature, the windows of the panel have straight, parallel edges of equal length, preferably defining an opening of substantially square shape.

Preferably, the flaps each have a maximum width which corresponds substantially to half the length of the straight edge of the frame which forms the pivot line of the respective flap.

According to one embodiment, the elements are formed by a metallic surface comprising 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 comprising a first straight edge corresponding to an edge of the first passage and along which the flap is attached to the frame, and one or more edges not connected to the frame so that the first edge forms a pivot line for the first flap with respect to the frame, and a second flap comprising a first straight edge corresponding to an edge of the first passage and along which the flap is attached to the frame or to the tongue, and one or more edges not connected to the frame so that the first frame forms a pivot line

for the second flap in relation to the frame or the 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 the frame, and having one or more edges not connected to the frame, so that the first edge forms a pivot line for the third flap in relation to the frame, and a fourth flap having a first straight edge corresponding to an edge of the second passage and along which the flap is attached to the frame or the tongue, and having one or more edges not connected to the frame, so that the first edge forms a pivot line for the fourth flap in relation to the frame or the tongue, the first edges of the first and second flaps being parallel to one another, while the first edges of the third and fourth flaps being parallel to one another, and that the element is partially inserted, on the one hand, into two windows of the plate of the same dimension and, on the other hand, into two further windows of the plate of the same dimension or into another window of the plate and a window of the floor with the same dimension engages, the first edges of the flaps having a length corresponding to the length of the straight parallel edges of the windows on which the first edges of the flaps rest after they have been folded over, the distance between the first edges of the first and second flaps and the distance between the first edges of the third and fourth flaps corresponding to the distance between the straight edges of the windows on which the first edges of the flaps rest after they have been folded over.

According to another embodiment, the curved plate has an outer surface extending between a lower edge and an upper edge, the plate having windows near the upper edge and the lower edge and being connected on its inner and/or outer surface to one or more rings having at least two windows, the windows having the same dimensions as the windows of the plate. Elements having two or more than two flaps, as previously defined, partially engage in a window of the plate and in a window of the ring to connect the ring to the plate. Preferably, one of the rings is connected to a plate forming the bottom of the basket. This bottom may have one or more holes to allow the drainage of liquids.

According to a detail of one embodiment, the curved plate has an inner surface, while the frames of the elements rest on the inner surface of the plate.

The invention also relates to a kit for the manufacture of such a basket according to the invention by curving a rectangular plate by connecting two parts of the plate by means of elements as defined in one of the preceding claims, the flaps of which are bent into windows of the plate, this kit comprising at least one rectangular plate, elements and preferably two rings, possibly a bottom and possibly a lid.

For receiving disposable packaging or other disposable products that are to be recovered or recycled, baskets according to the invention are used, in which, with the aid of a kit according to the invention, one or more baskets according to the invention are mounted essentially at the location where these packages or products are to be received, by arching a substantially rectangular plate and by connecting two parts of the plate by means of elements as defined in one of the preceding claims, the flaps of which are bent into windows in the plate, in which packages or products are collected in the basket(s), in which the baskets containing the packages or products are taken to a recycling or sorting point, in which the packages or products contained in the baskets are removed at the recycling or sorting point, and in which the basket is dismantled by bringing the flaps of the elements into a flat position in relation to the frame, so that the basket is brought back into the shape of the kit according to the invention. becomes.

The substantially rectangular plate of the basket according to the invention is made from a piece of recycled metal or from a recycled plastic, such as polyvinyl chloride, polyethylene terephthalate or even plasticized cardboard.

Each clip or mounting element consists, for example, of a metallic surface, "» ",

·

cut out by drawing, along a rectangular frame surrounding two symmetrical flaps that can pivot about fold lines arranged along opposite sides of the rectangular frame. The frame of the panel is designed to abut against the edges of a rectangular or square cut-out in the sides of the cardboard sheets that are superimposed and intended to be joined. The mounting elements or clips are preferably made of a material that can be attracted by a magnet.

The invention falls within the framework of the European directives that regulate the obligation to take back transport packaging and the recycling of disposable packaging. These directives are based on the principle that the polluter must ensure that he himself recycles the waste he produces. The manufacturer-producer is very often considered the polluter. He is responsible for preventing the littering of the packaging he produces and/or uses. It is therefore up to him to collect and/or recycle disposable packaging.

From this point of view, the invention proposes the distribution of kits for assembling and disassembling the baskets by the manufacturers and 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 the packaging, as provided for by the European Directives.

If the basket is intended to recover empty drinks bottles, the cylindrical body of the basket is preferably in the shape of an enlarged drinks bottle. It is made from a sheet of aluminium, for example recycled, and preferably bears an advertising inscription related to a soft drink. The upper lid is provided with an opening with a diameter of approximately 7 cm. If it is a question of recovering plastic bottles, an opening with a diameter of approximately 10 cm is preferably provided in the lid. The basket is made from a piece of plastic, preferably recycled, such as polyethylene terephthalate or polyvinyl chloride. The bottom of a basket intended for outdoor use can be made from a mesh insert, which has the advantage of allowing liquid to drain away.

According to an advantageous embodiment, the basket is provided with a collecting bag, this bag preferably having a substantially cylindrical shape which fits the inner wall of the basket and preferably being provided with a handle or a ring which serves as a handle. This handle is mounted, for example, on the outer wall which forms the bottom of the bag, this handle then allowing the bag to be easily emptied by simply hanging it upside down or hanging it with the bottom on an endless chain which comprises means or hooks for hanging the bags. The bag used is

preferably a woven bag made of a vegetable material such as hemp, linen, cotton, etc. The bag used is therefore preferably a non-plastic bag. The bag is preferably recyclable and can be cleaned, disinfected and possibly reused. The colour of the bags is preferably adapted to the products to be put in the bags, for example aluminium grey for metal waste, green for glass, blue for plastics, brown for Tetra Pak R waste, white for nappies, grey for household waste, etc. The bags preferably bear information such as drawings in large letters, etc. to make it easier to know which products are intended for which bag.

The mounting element or clip, which connects two windows of the panel by folding the flaps, forms a passage that can receive the end of a hook fixed to a support or wall so that the basket can be hung. When the element is placed on the inside of the basket, the frame preferably serves as a support for the end of the hook, thus protecting the panel.

The dimensions of the basket are chosen depending on the number of packaging or objects to be recovered. The useful volume of the baskets is determined depending on the needs and the space available in the places where the single-use packaging is distributed, used and/or discarded, for example the canteen of a school, the reception hall of a hospital building.

It is simply a logistics chain that runs from the supplier-manufacturer to the consumer.

The basket supplied in kit form makes it possible to reduce storage and transport costs. Due to its small size, the assembly kit is always available and within reach of the supplier of the products packaged in these packages. The assembly kit comprises, for example, a rectangular sheet of approximately 1 m ² , preferably flat, this sheet having two rows of cutouts along edges or borders of parts of the sheet intended to be superimposed. The volume required to transport the assembly kit is less than 25% of that occupied by baskets of the same size which would be nested one inside the other. The cost of the assembly kit is low and can easily be borne by the supplier or the manufacturer. Furthermore, dismantling the basket, for example to recover and recycle the collected packaging, is easy, the dismantled basket then possibly being able to be put back into kit form after washing the panel.

The basket is profitable because of the income from the public space and the product from the sale to processors of recyclable packaging. The advertising on the baskets can be chosen in such a way that the intended purpose of the basket is perfectly met.

These characteristics and other particularities and details of the invention will become apparent from the following description, which refers to the accompanying drawings which show, by way of non-limiting example, two embodiments of the invention.

Fig. 7 is a view of a cylindrical bag for a basket according to the invention; and

Fig. 8 is a view similar to Fig. 4 of another mounting element, the tongues of which, however, have been bent during its assembly.

In these figures, the same reference numerals designate identical and/or similar elements.

As shown in Fig. 1, a multipurpose basket 1 intended for the selective collection of disposable packaging with a view to its recovery and/or recycling is manufactured on site, preferably at the distribution points of products packaged in these packages, by clipping together a rectangular plate 2 curved to the dimensions of a reinforcing ring 3, a base insert and/or a lid 5. The rectangular plate 2 is made from a sheet of recycled metal or from recycled plastic, such as polyvinyl chloride, polyethylene terephthalate, or from plasticized cardboard.

The substantially rectangular plate 2 is curved so that two parts 2A, 2B of the plate overlap each other at least partially, this plate having a series of windows 9A, 9B having a first and a second edge 90, 91 which are opposite each other, parallel to each other and have an equal length "L" and are spaced apart from each other by a distance "e".

Four elements 6, which partially engage in windows of the plate, connect the parts 2A, 2B of the plate, which overlap, to each other so that the plate 2 is held in its curved shape. Each of the four elements is formed by a metal surface consisting of:

a frame 60 defining a passage P and having inner edges 61, 62, 63, 64 facing said passage, of which a first inner edge 62 and a second inner edge 64, which is opposite the first inner edge, are straight and parallel to one another, the first and second straight inner edges 62, 64 extending from one another by a distance "el" corresponding to the distance between the first and second opposite edges 90, 91 of the windows 9, which are connected to one another by the element 6,

a first flap 11 connected to the frame 60 along the first straight inner edge 62 and having edges HA, HB, HC that are not attached to the frame 60, so that the first inner edge 62 forms a pivot line for the first flap 11 in relation to the frame 60, and

a second flap 12 connected to the frame 60 along the second inner edge 64 and having edges 12A, 12B, 12C that are not attached to the frame so that the second inner edge 64 forms a pivot line for the second flap with respect to the frame 60.

- 16 -

The edges HB and 12B are rounded at their ends adjacent to the edges HA, HC and 12A, 12C.

The first and second inner edges 62, 64 of the frame of the element 6 connecting two windows 9A, 9B of the same size of the panel 2 have a length "Ll" corresponding 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 flap 11 and the second flap 12 rest near their fold line 62, 64 after the latter has been folded over.

Preferably, the frame rests on the surface of the part 2A of the panel facing the inside of the basket, while the flaps 11, 12 are folded over to engage the windows 9A, 9B (see Fig. 5) before being folded over on the surface of the part 2B of the panel facing the outside of the basket. When the flaps are folded over, correct positioning of the parts of the panel that are to overlap is ensured thanks to the fact that the flaps rest on the parallel edges of the windows 9A, 9B before being folded over and thanks to the fact that the side edges HA, HC, 12A, 12C limit or preferably prevent any translational movement of the element. When the flaps are folded outwards, dismantling the full basket is easy, since it is sufficient to bend the flaps, for example with the help of pliers, in order to bring them into one or the windows 9A, 9B.

The windows 9A, 9B of the plate have straight, parallel edges of equal length, which preferably

define an opening of substantially square shape. In this case, the flaps each have a maximum width X which corresponds substantially to half the length Ll of the straight edge of the frame which forms the pivot line for the flap in question.

The curved plate 2 has an outside extending between a lower edge 2C and an upper edge 2D. Near the upper edge 2D and the lower edge 2C, the plate 2 has windows 10 and is connected to a ring 3, 4 having at least two windows 30, 40, these windows 30, 40 having dimensions equal to those of the windows 10 of the plate. Elements 6, such as those shown in Fig. 4 and previously described, partially engage in a window of the plate and in a window of the ring, in order to connect the ring to the plate. The ring 3 is preferably arranged inside the basket, while the ring 4 preferably contacts the outside of the plate 2. The ring 4 is connected to a plate 41, which forms the bottom of the basket. A lid 5 makes it possible to close the basket.

The elements 6 are preferably formed by a metal plate or a surface cut out by drawing along a rectangular or square frame 60 which plays the role of a frame. To facilitate the folding of the flaps 11, 12 with respect to the frame, a groove can be provided which extends along the fold line. Preferably, a groove 66 is provided along the fold lines for each of the

opposite sides of the flat element 6. According to a particular feature, each flap is provided on its two opposite sides with two grooves 110, 120 which are located with respect to the grooves 66 at a distance substantially equal to twice the thickness of the plate 2. The grooves 110, 120 are parallel to the grooves 66.

By means of the assembly kits for baskets according to the invention, one or more baskets for the selective collection of packaging (aluminium foil, aluminium cans, plastic bottles, etc.) are assembled essentially at the place of return of the packaging or products. These baskets are made by arching a substantially rectangular plate and by connecting two parts 2A, 2B of the plate 2 by means of elements 6 as defined above, the flaps 11, 12 of which are turned into windows of the plate and folded over onto the external surface of the arched plate. Depending on the type of packaging, they are inserted into one or the other basket to ensure selective collection of the packaging or products. When they are substantially full or at regular intervals, the baskets containing the packaging or products are taken 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 placing the flaps 11, 12 of the elements in a flat position with respect to the frame 60 in order to return the basket to the form of a kit. Preferably, the basket is disassembled in order to remove the packaging contained in it.

or products. In this case, the elements 6 are preferably made of a material which allows them to be recovered from a sorting chain by means of a simple magnet. The plates, lids of baskets, bottoms of baskets, rings are in turn easily recovered by manual sorting or by means of a wide-mesh sieve which allows the recovered packages or products to pass through. Once dismantled, the components of the basket can be subjected to effective cleaning since all sides of the components of the basket are accessible. In this way, the presence of material or dirt or organisms on the parts of the basket which overlap, near the bottom, the upper ring, etc. is avoided.

The substantially cylindrical body defined by the curved plate of the basket is provided with a sign (colour to indicate the type of material or packaging to be thrown into the basket), an advertising message or a didactic message related to the product packed in the packaging to be recovered.

Fig. 8 shows a special element that can connect two windows of part 2A with two windows of part 2B. This element 6 is formed by:

a metallic surface having a frame 60 defining a first passage P1 and a second passage P2 separated from each other

separated by a tongue LA extending between two edges 6OA, 6OB of the frame 6,

a first flap 110 having a first straight edge HOA corresponding to an edge of the first passage Pl and along which the flap is attached to the frame 6, and having edges HOB, HOC, HOD that are not connected to the frame, so that the first edge HOA forms a pivot line for the first flap with respect to the frame,

a second flap Hl having a first straight edge HlA corresponding to an edge of the first passage Pl and along which the flap 111 is attached to the tongue LA, and edges HlB, HlC, HlD which are not connected to the frame 60, so that the first frame HlA forms a pivot line for the second flap 111 in relation to the 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 the frame 60, and having edges 112B, 112C, 112D that are not connected to the frame, so that the first edge 112A forms a pivot line for the third flap 112 with respect to the frame 60,

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 the tongue LA, and has edges 113B, 113C, 113D which are not connected to the frame 60, so that the first edge 113A forms a pivot line for the fourth flap with respect to the tongue.

The first edges HOA, HlA of the first and second flaps 110, 111 are parallel to each other, while the first edges 112A, 113A of the third 112 and fourth flaps 113 are parallel to each other. The element partially engages on the one hand in two windows of the panel with the same dimensions and on the other hand in two further windows of the panel with the same dimensions or in another window of the panel and a window of the floor with the same dimensions. The first edges HOA, HlA, 112A, 113A of the flaps have a length that corresponds to the length of the straight parallel edges of the windows on which the first edges HOA, HlA, 112A, 113A of the flaps rest after they have been folded over, wherein the distance between the first edges HOA, HlA of the first and second flaps and the distance between the first edges 112A, 113A of the third and fourth flaps corresponds to the distance between the straight edges of the windows on which the first edges of the flaps rest after they have been folded over.

In the form shown in Fig. 8, the flaps 110, 111, 112, 113 are folded along a substantially horizontal folding axis, so that the element makes it possible to connect two different rows of windows arranged one above the other. However, according to a more advantageous embodiment, the

«ft

Flaps 110, 111, 112, 113 are folded along a substantially vertical folding axis or along an axis substantially parallel to the central axis of the basket.

Fig. 8 shows in perspective a cylindrical bag 20 woven from a vegetable material and intended to be placed in a basket so as to fit against the inner walls of the latter. This bag has an opening 2OB for introducing into the bag the waste to be recycled and a bottom 2OA provided with a handle 21 for allowing the bag to be emptied by hanging it upside down (opening facing downwards).
