Description

Improvements to crates, crates and crates, made of wood, foldable and unfoldable. The invention is in the field of wooden containers, such as small crates used to contain generally and mainly fruits, vegetables and other products and foodstuffs intended for consumption, or adapted for another function such as for example that of packaging or display of other various objects.

Wooden crates have been around for a very long time. the quantity of wooden crates used is therefore immense, amounting to hundreds of millions of units depending on the country. These classic crates are essentially composed of raw wood planks assembled by steel clips to compose a petty cash structure open on the upper side. These steel clips have a high cost, and are also from a so-called non-renewable material on the planet. These crates are delivered empty in a definitive volume form and ready to receive their contents, which takes up a lot of space for their storage and transport, and generates enormous costs of energy expenditure, occupying a large volume for a low weight.

The small cardboard boxes (therefore wood-based) are generally held in their structure by gluing, without the possibility of folding and unfolding; they are therefore not unfoldable or collapsible, and therefore are also rigidly structured definitively, to suit their use; they therefore also occupy, empty, a large volume space.

All these containers have their completed and definitive forms and structures of non-modifiable container, and are manufactured to hundreds of millions of copies. Other containers, heavy structure for receiving commodities or heavy parts the most diverse, are foldable and partially unfolded; their connecting elements ensuring their folding / unfolding and closing, made of metal such as wire or shaped various machined and adapted, to withstand heavy loads; These containers and many others are made of non-bio-sourced and non-renewable materials, such as iron, and plastics, the latter being also cause of a huge pollution of the planet Earth and difficult to control. greatly in an "eco-product assessment" very unfavorable.

All these containers, produced to hundreds of millions of copies in their completed form of container, are by definition empty before their use to receive a content, and take up a lot of volume both in the storage areas as well as in the transports. A quick, comprehensive "eco-product" analysis immediately tells us the weight of transport impacts, CO2 emissions, running costs such as fuel, truck wear, road wear, wages, warehouses, to name only the most important criteria; the final "eco-product" balance sheet being strongly negative. Reducing these major drawbacks that are all these costs, in the volumes of storage and transport of empty boxes, is a major technical, economic and ecological challenge to which the present invention responds, in an innovative alternative solution. Invention patent 01182/2 957 897 / Leuvrey, of 24.03.10 "Foldable wood crate with flat vacuum and reconstitutable container" already provides a good solution in the removal of steel staples, in a completely different kinematics of folding and unfolding, which requires 4 clips to the 4 corners of the reconstituted crate containing it; the crate is constituted by only 4 clips pins encclipant vis-à-vis in 4clips receivers; the bottom of the crate is not mobile, because it permanently attached to 2 sides of the crate, by 2 links / hinge, the only 2 crate, device necessary for the kinematics of folding-unfolding of this crate thus comprising only 2 links on its base. 1 The box (C) described here according to the invention in this document is new in its means and kinematic folding-unfolding functions. In order to overcome these major drawbacks, the present invention proposes a new container, consisting of materials of bio-sourced and renewable origin, foldable flat vacuum and unfoldable re-constituable and containing, in the following qualities:. a job of great simplicity. considerable reduction of its volumes on pallets, by flat stacking. a strong lowering of manufacturing costs on automated industrial line. 100% organic self-destructible bio-sourced-vegetable or bio-based materials. replenable containing it in a very short time, by the user on the ground. longer life, with multiple possible re-uses. a relevant and real contribution to the challenge of protecting the planet. a valuation of the visual attractiveness of marketed consumer products. defense and competitiveness of wood, CO2 sink, preserved and strengthened. removal of steel staples. a general cost / benefit ratio highly efficient The present invention will be better understood through the drawings: FIG 1 represents 5 wooden elements composing the box, not connected, flat FIG 2 represents the body being assembled its side elements FIG 3 shows a top view of the box containing the 4 standing side members and connected and held together by links, and the FIG bottom element 4 represents the AA section of FIG 3 FIG. 5 represents the box folded flat.

FIG 6 shows the kinematics of the box in the form of container, view from below FIG 7 shows a view of the box unfolded and constituted containing. FIG 8 shows a top view of a corner of a box, with reinforcement FIG 9 shows a side view of a box corner according to FIG 8 FIG 10 is a view of a female-female clamp for locking the boxes FIG. 11 shows, according to FIG. 10, a view of the link (6p) made of self-programmable biodegradable polymer plastic, partly unfolded, and equipped with a traceability label holder. FIG. 12 represents a view in a version of the set of "cp" -shaped links. The term "box (C)" denotes here all types of containers, such as crates, crates, various boxes, of which the component materials their structure is of a bio-sourced nature and of renewable origin, and of a possible functional use and compatible with the present invention; the body is composed in the majority of its structure, raw wood material such as flat and rigid elements, planks or planks, obtained by any means such as sawing, slicing, peeling, and other transformations such as cardboard, plywood, particle board. The term "link" is also understood here hinge. To better understand the means and purposes of the invention, here is described a box (C) of rectangular type; the invention applies in the same principles of description in a volume form based on square-surface elements.

The invention comprises: 5 basic elements of rectangular shape, ie 2 long sides (1 a etl b) lateral + 2 small sides (2a and 2b) side, + 1 bottom (3) case. according to FIG 2, links (6) of hinge type and function, flexible and foldable quality in a central axis and not extensible are glued to the ends of the elements that are the short sides (2a, 2b) and the long sides (la, 1b), linking them together, in a looped and closed sequence, said sides being connected together alternately in the order (2b, 1b, 2a, la); each link (6) being glued on 2 elements, thus making them connected and definitely solidary. 2 Mechanisms by clips are absent here. This assembly device, at this stage, allows and already allows, here without the bottom (3), a flat folding of the recumbent elements of the box (C), and its unfolding in the standing position. The links (6) are placed either inside or outside the closed polygon obtained standing. In the device of the box (C) flat, according to FIG5, the bottom (3) of body, mobile function is then placed centrally between the elements (6) sides. 2 opposite sides receive on their inner faces, and by gluing, at least 2 links (15) of bottom, flexible and in tension between 2 opposite and symmetrical bonding points; The length of the link being equal to the inner distance of the box (C) between the two sides holding said links (15); these links (15) bottom are located at the bottom of the sides to which they are held, and inside the body, according to FIG 6. All links are made of bio-sourced material renewable, textile, such as cotton, linen, or jute, in a flat, woven form, and of very small thickness, with a non-stretchable structure and accepting folding; the term "non-extensible" means in the acceptance of a very slight relaxation only in its folded function and tension, and without harming the overall operation of the structural kinematic device of the body and its operation. The "bottom links" (15) are intended to receive and hold the bottom (3) of cash posed in 20 simple support on them at the bottom inside the volume of the box; these links (15) may possibly be in the form of a mesh with large mesh (8), as also the links (6) shown in FIG9. The bottom (3) of the body is mobile and comes in support and tension adapted to the inner faces of the 4 sides, blocking and maintaining the box permanently in its volume and functional structure of container. The bottom (3) of the body is monobloc and rigid and non-deformable, including if it is made of several elements assembled rigidly; as well as all the elements that are the sides. In summary, according to the invention, the body thus constituted, is according to the container, obtained by a series of 3 manipulations: 30 1 / the box is folded flat, in a single axis (17), the bottom (3) being housed between its 2x2 opposite sides; the flat box thus occupies a smaller volume. 2 / The body is unfolded in a standing position, manually by the user of the body 3 / The operator folds the bottom (3) on the links (15); the cashier is then in operational function. 35 4 / these repetitive operations (re-editable) in flat folding and unfolding in cash box. The bottom (3) of the body is monobloc to ensure its rigidity, necessary for its blocking and maintenance of the body in its container structure; the bottom of the body, can nevertheless be composed of several parts which by their rigid assemblages and complementarities 40 is always monobloc; this is applicable, if applicable, to the ratings. The links (6) and (15) are bio-sourced materials and therefore renewable, such as for example linen or cotton or jute. The adhesives used are preferably compatible with sanitary standards and also compatible with recycling. The bottom (3), in a variant, can also be held by a link (18) making it easier 45 "with one hand" the unfolding operation of the box for its reconstitution in operational container. Other slight variations and or adaptations to the body are possible, such as reinforced sides, a bottom (3) composed of several elements, or a body cover added to the device. All these elements being connected, the structure of the empty and completed box can lie down and flatten naturally, manually, according to Fig5, the bottom (3) of cash being positioned in the center of the device; this device makes it possible to stack the boxes flat, thus allowing the 3 to reduce the volume costs, compared to a box according to receiving and containing various objects (various parts, fruits, vegetables) which are intended for it. This reduction, in a very advantageous ratio, according to the depth of the box, volumes on these boxes "empty" and stacked flat brings an absolute advantage in the reduction of the costs (storage transport, labor, time, balance CO2). The flat bed is mechanically replenable in its cash function, by a simple manual gesture by any operator using it, in all fields of activity; for example, the market gardener, in his field of culture, in 2 or 3 seconds, opens the box by unfolding it and folds the bottom (3) which blocks and maintains the box in its structure according to receiving its contents of vegetables. The manufacturing costs of the body according to the invention are low, compared with the usual techniques. The links (6) are flexible but not elastic, composed of a bio-sourced material, such as cotton, linen; the entire body, for example wood, is a 100% eco-product; The box may include, in association, partially or not, elements in other bio-sourced materials such as cardboard. In another (p) manufacturing option, the bonds (6p) are made of polymeric plastics (and derivatives such copolymers) which are receivable and or self-destructing by controlled action of macromolecules such as the enzyme that plays a role. catalyst by bio-chemical reaction; these links then have a structure that is stiffer and more resistant in tension and in compression than textile fabric structures, while keeping the quality of folding in the folding axes, and do not then require additional reinforcements to support the loads at stacking crates full of products; these links (6p) are glued to the sides as the links (6). Alternatively these links are attached to the wooden elements, in the technique already described in the patent no. 01182/2 957 897 / Leuvrey, of 24.03.10 already cited: the link has spikes embedded in its mass, and the sides have vis-à-vis holes for the passage of the tips longer than the thickness of the side; fixing the polymer link permanently sealed to the wooden side, is obtained by the flap (31) hot end of each tip; or by other means such as by clipping the polymer link on wood or "by force". The links (6p), according to FIG11, a length equal to the height of the walls of the body, are fixed in the upwardly displaced position, in order to keep the boxes in an aligned stack and stable.

The links (6p), in option, comprise in lateral extension a zone (32) intended to receive a label (33) adhesive traceability of the content, very useful device in view of the difficulty or impossibility to stick an adhesive label on wood more or less wet or wet when harvesting fruits and vegetables for example at all times; the zone (32) can also be in the form of a pouch in which a traceability card is housed. All the links (6, 6p, 15p) are recyclable, and preferably self-destructing self-programmed polymers, thus bringing this enormous advantage in the question of combating the wild and uncontrolled pollution of non-wood and non-organic components. vegetal sources integrated into crates; synthesis and successful and successful completion of an aesthetic and functional valuation other in a fund essentially wood, according to the invention, 100% eco-product. These links (6p) of polymers are rigid to hold firmly to the compression of the loads and foldable only in profiled areas in folding ability, and with respect to their different function and flexible folding-unfolding kinematics in flat shapes or wired in their function (15, 15p) support 55 of the bottom (3).

4 The box, in another option, according to FIG8 and FIG9 can receive rigid reinforcements (20) of any kind bio-sourced preferably wood, round or other suitable form, a section greater than the section of the sides , placed at the corners of junction and folding sides, and held and clamped against the sides by the links (6). This reinforcement (20), of a length less than the height of the sides with which it is associated, is positioned slightly offset in an overflow position (21) of the upper edges of the sides of the box, creating at its base a free space . Thus two complementary qualities of the body are obtained: that of reinforcing its functional structure at the level of the unfolding zones of the upright body and in its function as a solid and heavy container, in particular by their partial and integral interlockings in their constantly vertical stacking and aligned. In another variant, this device reinforcing the corners of the body, is obtained by the clamps (23) nestable on the sides and the four corners of the body, forceps forming an angle of 90 °, a height less than the height of the side of the box (having 4 sides of equal height 15), to also obtain the nesting and maintenance of the boxes by vertical stacking. The clamps (23) are placed manually and very quickly at the last moment, when unfolding in reconstituting / container of the cash register, by the user of the cash register; the tongs (23) being delivered separately from the box folded flat; simply. These wedge clamps (23) are made in a single piece and made of a rigid material 20 and resistant to their use, in female / female function obtained by a wall (24) in the longitudinal axis (25); the tongs (23) are at least recoverable and recyclable materials, such as bio-sourced materials such as for example in thermo-plastic corn starch, or a bio-programmed bio-autodestructible material. In another option, in view of an optimized manufacturing line of the box (C), the links 6p and 15p are connected together in a solid manner to form a cage "18p" such as a shell, open on all planes (FIG. ), semi-rigid in a clear and light structure; "Semi-rigid" here means that the adapted structure of the stand alone is rigidly in its cage shape and that its folding areas are however flexible enough to fold and unfold, in order to meet the kinematics folding and unfolding the crate according to the invention; "P" designating in the present description the quality of "plastic", here links 6p and 15p and the cage 18p; the whole "18p" cage is made of bio-programmed bio-programmable (bio-programmable) plastic polymer; the cage is fixed integrally to the wooden elements that are the sides (1a, 1b, 2a, 2b) and bottom (3), by any means various and suitable associated such bonding, clipping. The cage (18p) is preferably located inside the body (C). The global and optimum eco-balance is thus obtained by the sum of the real technical advantages in the present invention, including: * its flat packaging (16) and of small thickness excluding content considerably reducing up to 40 times less volumes empty storage and transport, * 40 * the elimination of steel staples (forbidden in food), * all components being bio-sourced and renewable, and or self-destructible self-destructive * wood, in its aesthetic value, its technical qualities, sinks of CO2 and renewable material, 45 * the use of technical glues compatible with the manufacture and the function of the box, * lines of modern and competitive productions. The invention, with regard to the description above, concerns all types of containers in functions, contents, similar and adapted. 5
