Description

Conditioning and packaging for the transport of plants in plugs, and set of blanks for carrying out such packaging

The invention relates to the technical field of packaging, and in particular packaging intended for the transport of plants in plugs. The invention also relates to a set of blanks of cardboard material pre-cut and then mounted by folding to form the packaging itself.

In the present application, “conditioning” means a means making it possible to protect an object from external and unwanted stresses, for example temperature, shocks or crushing force.

In this application, “packaging” means a container for receiving packaging.

In the present application, the term “transport” means any movement of the packaging, regardless of the way in which it is carried out, that is to say by being carried by a person, or deposited in a transport vehicle by example a truck, a plane or a train. Such transport can be carried out over a few meters, for example within a warehouse during handling operations, but also over a much greater distance, for example several hundred kilometers.

In the present application, the term "ball plants" means a plant comprising a free vegetative part (for example a stem), and an established vegetative part (for example roots). The implanted part is surrounded by a mass of substrate allowing the conservation of the plant and/or the evolution of the plant during transport. Generally, the substrate is natural, and is for example earth, sand, loam, or humus.

For reasons of simplification, throughout the remainder of the text, the term “plant” designates a plant in a plug.

For a plant in a plug, the implanted part is however devoid of a receptacle, the substrate having undergone a compression process allowing it to be held around the plant. Thus, the substrate undergoes compaction allowing the formation of a lump having a predetermined size and shape. The substrate is suitable for receiving a plant seedling or transplanting of an already formed plant.

Often, such a mound has a parallelepiped shape, preferably cubic with dimensions of 4x4x4 cm or 6x6x6 cm. Such dimensions are standardized.

It is necessary to maintain the integrity of the root ball, in particular so that the plant can have a substrate that physically maintains its habit, as well as biochemical resources allowing it to live. The substrate must therefore keep its shape, and also have controlled humidity.

The main characteristic of plug plants is that they are made available to an intermediate or final user without a receptacle. In other words, once the user has the plant in a plug, he can either put said plant in a plug in the ground, or place it in a receptacle of his choice which is itself furnished with a substrate.

The absence of a receptacle gives plug plants a large number of advantages. Thus, such a property is favorable from an economic point of view since the user does not have to purchase an additional receptacle if he already has one, or if the plant is intended to be placed in the ground , for which no particular receptacle is necessary.

In addition, from an ecological point of view, the receptacles in which plants are generally sold are often made of thermoplastic material, for which recycling can be complex and expensive.

Furthermore, the transport of such plants can be achieved inexpensively, the absence of a receptacle making it possible to limit both the weight and the bulk of such plants. Such a property is particularly advantageous in the case of online commerce, since shipping can be carried out at a lower cost.

In addition, the absence of an initial receptacle allows the plant to only be transplanted once and limits the stress associated with this operation.

However, plants in bare clumps have the disadvantage that maintaining the integrity of the substrate is difficult over time. Indeed, the substrate may lose its cohesion, and thus crumble or disintegrate. Such a loss of cohesion may be the result of excessive drying of the substrate or of mechanical actions (shocks, vibrations, etc.).

Such a disadvantage particularly arises during the transport of plants, in particular when the plants are sent in courier packages. Indeed, the constraints linked to such a method of shipping are significant, since the plants are inevitably subject to shocks and vibrations, linked to their transport, for example in the event of maneuvering. In addition, the humidity and temperature conditions during transport cannot be controlled.

Also to deal with such criticalities, the plants in plugs are placed in a box made of cardboard equipped with an additional cushioning wedging element, that is to say which will wrap the plugs by absorbing shocks. In general, such a cushioning element is wood or cardboard crimp, which offers the advantage of good biodegradability, has a reduced cost, and is light.

However, the use of such a wedging element is not optimal. Indeed, such an additional wedging element has significant dimensions, which impacts the optimization of packaging and impacts the number of plug plants that can be transposed per package. In addition, the installation of such a damping element is not easily reproducible, which has an impact on the speed of packaging the plants in plugs. Finally, in the case of a damping element made in curls, the conservation of the integrity of the blocks is limited in the case of transport in packages by courier.

There are packages that allow objects to be held in place during transport.

For example, document GB 1580900 A describes packaging comprising compartments formed by folding a blank. However, the formatting of such packaging is complex, and requires prior learning. It is also not possible to modify the size of the compartments thus formed other than by modifying the blank. Furthermore, such a compartment would not be capable of allowing protected disposal given that no location is described to allow the free vegetative part of the plant to be received.

EP 2913274 A1 also discloses an example of packaging making it possible to hold objects, in particular bottles, in place. More precisely, the document is a box comprising face-to-face central fields provided with recess. However, it is not easy to apply such a principle for plants in plugs, given that the plugs could not be maintained in the event of a sudden shock. In addition, such conditioning does not offer any solution for maintaining the humidity of a clod.

The present invention aims in particular to respond to the aforementioned drawbacks.

A first objective is to propose packaging for the transport of plants in plugs.

A second objective is to offer such packaging to optimize the quantity of plants to be transported.

A third objective is to propose such packaging to best preserve the mechanical and hygrometric integrity of plants in plugs during their transport.

A fourth object is to propose such packaging which can be easily put into volume, without the use of additional fixing material.

A fifth object is to offer packaging allowing you to receive packaging as presented above.

A fifth object is to propose a set comprising a plurality of blanks so as to allow packaging as presented above to be put into volume.

We refer to the representing a packaging 1 for the transport of plants in a mound P comprising a free vegetative part PVL and an implanted vegetative part (not visible in the figures) in a mound M.

As shown on the , the packaging 1 comprises a box 2 within which a packaging 3 is placed. Such packaging 3 allows the transport of plants in a clod P, and more precisely the maintenance of plants in a clod 3 during their transport. Packaging 3 is intended to be placed, positioned in packaging 1.

As explained later in this text, the volume and maintenance of the packaging 3 within the box 2 is for example carried out by folding the packaging 3 then insertion within the box, and does not require any additional fixing material for example glue, staples.

Packaging 1 and packaging 3 are made entirely of a semi-flexible material, that is to say capable of being folded after application of manual force. Advantageously, use is made of cardboard or corrugated cardboard, which offers an interesting compromise in terms of cost, robustness, mass and ease of manufacturing. The choice of such a type of material can be made without problem by a person skilled in the art.

In the , it can be observed the presence of a single packaging 3, but in other embodiments, a plurality of packaging 3 are stacked on top of each other. In this way, it is possible to optimize the filling of packaging 1, that is to say, to be able to limit the quantity of empty space in box 2, once it is closed.

Advantageously, the box 2 comprises a bottom 4, advantageously rectangular, and a plurality of walls 5 extend projecting from the bottom, preferably perpendicular to the bottom, as shown in the figure. . Also, the box defines a parallelepiped. Such a geometry is advantageous for optimizing the filling of P-ball plants.

In order to allow it to be closed easily, the box 2 comprises for example a cover 6, advantageously articulated to one of the walls 5. Preferably, the cover 6 comprises a tongue 7 capable of being inserted within a wall 5 placed directly opposite the wall 5 with which the cover 6 is articulated.

We now refer to Figures 1, 2 and 4 representing packaging 3.

As can be observed, packaging 3 comprises a plate 8, two support strips 9, 10 and at least one removable partition 11, fitted onto the support strips 9, 10.

The support strips 9, 10 allow the formation of a compartmentalization structure 12 defining a plurality of compartments 13, 14. Such compartments 13, 14 are capable of receiving and maintaining the integrity of the plants in a clod P as explained later in this description.

We define with respect to the plate 8 an orthogonal reference XYZ comprising three perpendicular axes in pairs, namely:
- an X axis, defining a longitudinal direction;
- a Y axis, defining a transverse direction merged with the direction of extension of the partitions, horizontal, which with the X axis defines a horizontal XY plane;
-a Z axis, defining a vertical direction, perpendicular to the horizontal XY plane.

Advantageously, the plate 8 takes the form of a plate with flaps. More particularly, the plate 8 comprises a panel 15, first flaps 16, and second flaps 17. The first panel 15 extends substantially along a horizontal plane, the first flaps 16 and second flaps 17 extending respectively along a plane longitudinal and a transverse plane.

Advantageously, the plate 8 comprises at least one opening 33, preferably two openings 33, for example of circular shape made on the panel 15, making it easier to grip the plate 8 when putting the packaging 13 into volume.

As can be seen on the , the flaps 16, 17 are hinged to the panel 15, and erected perpendicular to the panel 15. The flaps 16, 17 have upper contours 32, when the flaps 16, 17 are erected, each of them extends in a plane horizontal. Such an arrangement makes it possible to form a well-closed receptacle, which is favorable for forming an enclosure suitable for retaining humidity.

Advantageously, and as can be observed on the , the box 2 is defined so as to have a bottom 4 of complementary dimension to the plate 2 so that the flaps 16, 17 are in contact, and more particularly in support against the walls 5. In this way, the plate 8 forms a stable and robust support to block a compartmentalization structure 12 when the tray 8 is placed within the box 2.

We describe more particularly a compartmentalization structure 12, with particular reference to Figures 2 and 5.

In the embodiments shown, the packaging 3 comprises a first support strip 9 and a second support strip 10, identical, and arranged substantially longitudinally on the plate 8, which makes it possible to define a compartmentalization structure 12 sufficiently robust to be able to allow the stacking of two packages 13 one on top of the other.

Furthermore, such an arrangement allows the formation of side compartments 13 and central compartments 14 between two side compartments 13. The side compartments 13 are thus capable of receiving a lump, which is then protected from impacts.

In other embodiments not shown, and not described below, the packaging 13 only comprises a single support strip 9, 10.

The support strips 9, 10 comprise a first flap 18 and a second flap 19, advantageously, the flaps 18, 19 are rectangular and substantially identical.

As can be observed in the figures, each of the flaps 18, 19 comprises a first side 20, advantageously free and a second side 21. The second sides 21 are attached to each other, connecting the flaps 18, 19 together, so as to articulate them together, for example by defining a fold line. In this way, the flaps 18, 19 are oriented relative to each other, and define an acute angle in a cross section. The support strips 9, 10 then have the shape of an angle.

Thus, the second side allows for example a variation in the distance between the first flap 18 and the second flap 19, if a bringing together thrust aimed at reducing the distance between the two flaps 18, 19 is exerted on the support strip 9, 10.

In the configuration shown in the figures, the support strips 9, 10 rest on the plate 8 via their first side 20. In this way, the support strips 9, 10 are sufficiently stable to be able to hold the partitions 11 without it is necessary to use an additional fixing means. The installation of packaging 1 is thus easily achievable.

In the embodiments shown, the support strips 9, 10 comprise notches 22 and apertures 23, arranged alternately with respect to each other.

The notches 22 define a location devoid of material, that is to say a recess according to a predetermined pattern. Advantageously, the notches 22 include edges 35 parallel to each other. Thus, the support strips 9 are devoid of materials in a substantially transverse thickness. In this way, a space is left to allow the insertion of a partition 11.

So that a partition 11 can rest on a support strip 9, 10, a support surface 24 is left between the second side 21 and the notch 22. Such a support surface 24 is sufficiently resistant to be able to support the nesting of a partition 11.

As shown in the figures, the openings 23 have a rounded shape, so as to be able to receive a free vegetative part of a plant in a clod P. However, other geometries can be considered, depending in particular on the shape and the size of the free vegetative part to receive.

We now describe the partitions 11 in more detail, with particular reference to Figures 4 and 5.

Advantageously, the partitions 11 are in the form of substantially rectangular plates, so as to occupy a minimum space in the packaging 13.

In the embodiments shown, a partition 11 comprises two side edges 25 coming into contact, resting against the first flaps 16, the angle between the partition 11 and the first flaps 16 being 90°. In this way, it is possible to form between two partitions 11 and a flap 16 side compartments 13 of parallelepiped shape complementary to the shape of the clods M of the plants P. Also, a minimum of space is lost, which makes it possible to optimize the filling of the packaging 1. In addition, the humidity of the clods is more easily retained in such side compartments 13.

In the embodiments shown, the partitions 11 also include lateral banks 25, first banks 26 and second banks 27, parallel to each other, delimiting in particular the height of the compartments 13, 14.

Advantageously, the first edges 26 come into contact and are flush with the panel 15 so as to limit the spacing between the panel 15 and the partition 11 as much as possible. In this way, the air circulation is reduced within the packaging 13. , which allows humidity to be preserved as best as possible within compartments 13, 14.

Advantageously, the partitions 11 integrate a first cutout 28 and a second cutout 29, the transverse spacing of the first and second cutout 28, 29 corresponding to the distance in a transverse direction between a notch 22 of the first support strip 9 and a notch 22 of the second support strip 10. Such an arrangement allows the nesting of a partition 11 on one of the strips 9, 10.

Preferably, a cutout 28, 29 comprises a first stopping edge 30 and a second stopping edge 31. The first stopping edges 30, 31 are for example perpendicular to the first edge 26. Such stopping edges 30 , 31 make it possible to hold the first flap 18 and the second flap 19 in position at an acute angle, while retaining the thrust aimed at bringing the flaps 18, 19 closer together. In other words, thanks to the second side 21, it is possible to vary the distance between the first flap 18 and the second flap 19 in reaction to the thrust exerted by the first stopping edge 30 on the first flap 18 and the second edge. stop 31 on the second flap 19, when a partition 11 comprising the cutout 28, 29 is fitted onto the support strip 9, 10.

In this way, the support strips 9, 10 are held in an angle position, which gives the compartmentalization structure 12 a stability making it possible to limit the risk of crushing coming from an effort exerted in a vertical direction. Also, the risks of damage to plants in plugs P placed in packaging 13 are limited.

As can be observed in the figures, and in particular on the , the dimensions of the partitions 11, and in particular of the cutouts 28, 29 are defined in such a way that the first edges 26 and the first flaps 16 and/or the second flaps 17, which have upper contours 32 belong to the same fictitious horizontal plane. In this way, the first edges 26 and the upper contours 32 form supports allowing the possibility of positioning a tray 8. Such an arrangement allows the stacking of two packages 13 on top of each other, which allows the optimization of filling a box 2.

Advantageously, a second edge 27 is provided with one or more notches 34, preferably located between the cutouts 28, 29. Such notches 34 make it possible to create locations in order to receive plants in a mound P whose free vegetative part PVL is extends longitudinally. Such a property is advantageous because it makes it possible to condition P plants of different sizes.

We now give results of comparative tests aimed at evaluating the maintenance of humidity of P plants over time. The tests were carried out for three different situations.

In a first situation (situation A), fourteen P plants were placed in prior art packaging consisting of a 7 mm double-corrugated cardboard box, the P plants being held by means of wooden crimps placed all around the plants, between the plants and the cardboard box, to a thickness of 3 cm.

In a second situation (situation B), fourteen P plants were placed in packaging 3 made of simple corrugated cardboard 3 mm thick.

In a third situation, the P plants are placed in the open air, and without boxes.

Hygrometry measurements were carried out simultaneously for all the situations described above. It can be considered that the temperature conditions were identical for each situation.

The measurement results can be found in the following table.

The test results show that when subjected to identical temperature conditions, the hygrometry of a P plant remains higher over time in a packaging 1 subject of this document in comparison with a root ball of a P plant placed in a packaging state of the art or a P plant in the open air. Also, it is possible to maintain the humidity above 90%, a minimum value for which it is recognized that a plant presents a minimal risk of deterioration due to water stress.

We refer more particularly to the representing a set 40 consisting in particular of a first blank 41, a second blank 42 and a third blank 43, pre-cut and made of cardboard.

Such an assembly 40 allows the volume of packaging 13 to produce packaging 1.

The first blank 41 is intended to form the plate 8, and comprises the rectangular panel 15. The rectangular panel 15 comprising first flanks 44 and second flanks 45 provided with flaps 16, 17.

The flaps 16, 17 are hinged to the panel 15 and intended to be erected perpendicular to the panel 15.

Advantageously, the first blank 41 has at least one opening 33, preferably two, for example of circular shape made on the panel 15, facilitating the gripping of the plate 8 when putting the packaging 13 into volume. The openings are advantageously arranged in the vicinity of the surface of the first blank 41.

The second blank 42 is intended to form the substantially rectangular support strip 9, 10, and integrates a first flap 18 and a second flap 19 which are articulated together so as to be able to be oriented relative to each other by defining an acute angle .

It should be noted that the second blank includes at least one aperture 23 and two notches 22 extending within the first flap 18 and the second flap 19, the aperture 23 being arranged between two notches 22. Advantageously, it is provided a multitude of openings 23 and notches 22, depending on the number of compartments 13, 14 that we wish to create.

On the second blank 42, the apertures 23 have for example a substantially oval periphery 36, or else defining two ogives symmetrical with respect to one another with respect to a plane orthogonal to the extension surface of the second blank 42 , and passing through the second side 21.

The third blank 43 is intended to form at least one partition 11. The third blank 43 comprises a cutout 28, 29 capable of holding the first flap 18 and the second flap 19 in position when the flaps 18, 19 are oriented defining between them an acute angle. It should be noted that the cutouts 28, 29 are provided on the first edge 26.

The third blank 43 also includes notches 34, provided on the second edge 27, obtained for example by perforation of the third blank 43.

In order to facilitate manufacturing, in embodiments not shown, a plurality of blanks 41, 42, 43 are produced, each of the flanks being respectively connected to each other, for example by a weakened line.

Advantageously, the support strips 9, 10 are connected to each other via the third side 37.

Advantageously, the partitions 11 are interconnected by their first edges 26.

The formatting of an example of packaging 1 and packaging 3 associated with it can be done as follows.

In a step of shaping the support strips 9, 10, the flaps 16, 17 are raised at 90° by folding the flaps 18, 19 along the second side 21, as can be observed on the .

In a compartment creation step, the partitions 11 are fitted onto the support strips 9, 10 by inserting the notches 22 within the cutouts 28, 29. When inserting the notches 22 within the cutouts 28, 29, the stopping edges 30, 31 exert a thrust making it possible to fix the angle between the flaps 18, 19. In this way, the force of spacing of the flaps is stopped by the stopping edges 18, 19.

During a stage of shaping the tray, the flaps 16, 17 are raised at 90° by folding along the sides 44, 45. The tray is then inserted into the box 2.

In a finalization step, the compartmentalization structure is positioned on the plate 12, the side edges 25 and the third sides 37 respectively allowing the first flaps 16 and the second flaps 17 to be pressed against the walls 5.

Packaging 1 and packaging 3 as described above offer several advantages:
- ease of shaping from blanks with simple shapes, without the need for additional equipment, and without the need for specific learning,
- significant modularity, the partitions being easily removable, the compartments having a scalable size, and easily adaptable to the type of P plug plants to be transported,
- optimized filling with P-ball plants, empty spaces can be reduced to their strictest minimum,
- increased protection of plants in clods, the movements of said plants are strongly limited due to compartmentalization,
- prevention of drying out of plants P, compartments 13, 14 making it possible to limit air circulation, and therefore evaporation.
