Description

[0001] The field of the invention is that of logistics. More precisely, the invention relates to a package, also called a packaging means, i.e. a container, for the transport of objects between two destinations.

[0002] To transport an object safely, packages such as boxes made of plastic materials and cardboard boxes are known.

[0003] Generally speaking, parcels consist of a box with a base and a peripheral rim which together define a storage volume in which at least one object to be transported is housed.

[0004] The packages include également a movable lid relative to the case, or attached to the case, this lid being able in particular to adopt a closing position of the storage volume in which the lid closes the storage volume of the case.

[0005] These packages are conventionally foldable. They are therefore mobile between a configuration in which the box is formed and defines the storage volume, and a flat configuration in which the package is collapsed on itself, producing a smaller footprint.

[0006] More specifically, the peripheral rim includes: a first panel; a second panel; a third panel opposite the first panel; a fourth panel opposite the second panel.

[0007] Each panel can therefore adopt: a storage position in which it extends substantially parallel to the bottom; a usage position in which it extends substantially perpendicular to the bottom.

[0008] Documents WO 2020 / 104339, FR 2 351 865 and WO 2015 / 198504 describe such a collapsible package which has a space-limiting storage configuration and another deployed configuration for use in packaging and conditioning.

[0009] Before transporting an object, a user picks up a package in its flat configuration in order to shape it. Indeed, most often, when storing the package, the panels of the peripheral edge are in their storage position, which implies that the package is in the flat configuration.

[0010] The user must then configure the box, that is, define the storage volume by positioning each of the peripheral rim panels in its position of use.

[0011] The user can then insert an object into the storage compartment and position the lid in the closed position of the storage compartment.

[0012] Typically, parcels are made of cardboard. These cardboard parcels are generally used for only one shipment or a very limited number of shipments.

[0013] These cardboard packages tend to degrade particularly quickly depending on the handling conditions of these packages, as well as the environmental conditions to which they may be subjected.

[0014] Consequently, given the volumes of cardboard used in logistics transport, it can be considered that the use of these boxes is not ecological and particularly resource-intensive, even taking into account the simple and easy nature of producing this type of package.

[0015] Recently, reusable parcel projects have emerged.

[0016] These reusable packages can be used many times before needing to be recycled or repaired. To this end, these packages have walls made of materials that are stronger and more durable than cardboard.

[0017] In the end, although they have a more complex and expensive design or manufacturing process than cardboard boxes, the ecological footprint of such reusable boxes is better.

[0018] However, the use of reusable packaging raises some problems.

[0019] Indeed, the issue of storing used packages—that is, packages received by a recipient and requiring storage before reuse or return—is a real problem. In practice, when a user receives a package, they are not always able to return or reuse it immediately and must set it aside. However, in its intended use, a cardboard package takes up considerable space.

[0020] Consequently, solutions aimed at reducing this congestion are needed.

[0021] Generally, a package can be returned to its flat configuration. However, experience has shown that the bulk of a package in its flat configuration, and which has already been used, i.e., which has already been shaped at least once, is often greater than that which it had in its flat configuration prior to its first use.

[0022] For example, a package that has already been used and is returned to its flat configuration may tend to redeploy, even slightly, resulting in a configuration in which it occupies a larger volume than in its flat configuration. Of course, these packages can be forcibly kept flat, but this effect can still occur even in the absence of external constraints.

[0023] The invention aims in particular to overcome the drawbacks of the prior art.

[0024] More specifically, the invention aims to provide a reusable package that has a limited size when not in use and that retains its limited size.

[0025] Some of the objectives of the invention are achieved by the package according to claim 1.

[0026] This document describes a package comprising a base extending between a front end and a rear end along a first axis, the package also comprising panels including: a front panel pivotally mounted on the front end of the base; a rear panel pivotally mounted on the rear end of the base; side panels pivotally mounted on the base; a lid pivotally mounted on one of the front or rear panels; the package being foldable between: a configuration of use in which the base, front panel, rear panel and side panels form a box defining a storage volume, and in which the lid is capable of closing the storage volume; a flat configuration, in which the panels extend substantially parallel to the base; with in the flat configuration of the package: the side panels are in a position folded against the base;One of the front and rear panels is in a folded position against the bottom, overlapping the side panels, and the other of the front and rear panels is in a pivoted position, extending from the bottom; the lid is in a folded position against the bottom, overlapping the side panels.

[0027] The package includes, in its flat configuration, anchors between the base and at least one of the panels in a folded position against the base, each anchor exerting a holding force in its folded position of one of the panels against the base, the anchors comprising: at least one first anchorage near the front end of the bottom; at least one second anchorage near the rear end of the bottom; the first anchor(s) being spaced from the second anchor(s) along the first axis.

[0028] Thus, in its flat configuration, the package has a limited footprint.

[0029] Indeed, thanks to the principle of the invention, the package in its flat configuration maintains its shape and size, and it is prevented, in the absence of a voluntary action, from deforming the package, in particular through a "shape memory" effect.

[0030] More specifically, a reusable package, which can thus be folded between a usage configuration and a flat configuration, is likely not to be able to naturally maintain a flat configuration because of pivot connections between some of its elements, and the nature of the materials forming the panels of the package.

[0031] The package according to the invention has a pivot joint between its front panel and its base, as well as between its rear panel and its base. The lid is also pivotally mounted on either the front or rear panel. These three pivot joints are therefore susceptible to opening and may not maintain the angle they are designed to hold when the package is in its flat position.

[0032] Thanks to the invention, the first anchor which is located near the front end of the bottom (and thus of the pivot joint between the front panel and the bottom), as well as the second anchor which is located near the rear end of the bottom (and thus of the pivot joint between the bottom and the rear panel), help to keep the panels and the bottom of the package substantially parallel, and thus ensure that these elements of the package keep this position when the package has been moved into its flat configuration.

[0033] For example, if the rear panel extends beyond the base and the pivot joint between the rear panel and the base has an elastic effect that tends to pull the rear panel upwards, then the second anchoring compensates for this elastic force by pressing two of the package elements located near the rear edge of the base against each other. This prevents the package from losing its flat configuration.

[0034] According to an advantageous solution, the base comprises two lateral ends on which the side panels are pivotally mounted; the package includes: two first anchors distributed respectively near each lateral end of the bottom, at the same length along the first axis; two second anchors distributed respectively near each lateral end of the bottom, at the same length along the first axis.

[0035] Thanks to these four anchors, maintaining the package in its flat configuration is optimized.

[0036] Indeed, the anchors are then distributed at different points on the package and the efforts to keep the package flat are distributed on each of these four points, and this in particular as close as possible to the different pivot connections of the panels with the bottom.

[0037] According to an advantageous solution, the lid is pivotally mounted on the rear panel, either the lid or the front panel having: a first part of the or each first anchorage, the bottom having a second part of the or each first anchorage complementary to the first part or parts; a retaining element by covering the other of the lid or front panel; and, in the flat configuration of the package, the retaining element locks said other of the lid or front panel in its folded position against the bottom.

[0038] In this way, the first anchor(s) allow one of the lid or front panel to be held flat against the bottom, while the other of the front panel or lid is held flat against the bottom by means of the overlapping retaining device.

[0039] This optimizes the maintenance of the package in its flat configuration.

[0040] According to a preferred design, the first anchor(s) and / or the second anchor(s) are of the clip-on type, with the package passing through in its flat configuration likely to cause the anchors to clip on.

[0041] Thanks to this type of anchoring, maintaining the package in its flat configuration is particularly easy to implement because it is simply a matter of moving the package from its usage configuration to its flat configuration to trigger each of the clip-on type anchors.

[0042] According to a preferred design, the package includes a locking mechanism comprising at least one movable actuator between: a locking position in which, in the flat configuration of the package, the first anchor(s), and / or the second anchor(s), known as lockable anchor(s), are locked, and an unlocking position in which the lockable anchor(s) are inoperative.

[0043] In this way, a user of the package must activate the actuator in order to move the package from its flat configuration and fold it into its usage configuration.

[0044] The transition of the package from its flat configuration to its usage configuration thus results from a voluntary action by its user.

[0045] Advantageously, the locking mechanism includes elastic return means for the actuator(s) tending to return them from their unlocked position to their locked position.

[0046] Thus, an accidental actuation of the actuator is compensated by the elastic return means which allow the actuator to be returned to its locking position.

[0047] Furthermore, when combined, where appropriate, with a clip-on type anchor, the lockable anchor offers simple and intuitive operation. Indeed, moving the package in its flat configuration causes the anchor to clip into a locked position via an actuator and elastic return means that maintain the actuator in this locked position. In this case, only deliberate activation of the actuator and appropriate handling of the package will allow it to be moved into its operating configuration.

[0048] According to a preferred design, only some of the first or second anchors are lockable anchors, the others of the first or second anchors being force-releaseable.

[0049] This design simplifies the integration of different functions on the anchors.

[0050] According to another preferred design, only some of the first or second anchors are lockable anchors, the others of the first or second anchors being disarmable by means of pivoting the panel located in a folded position in line with the bottom beyond this folded position in line with the bottom.

[0051] In this way, the disarming of anchors that are not "lockable anchors" is achieved through a particular kinematic deployment of the package from its flat configuration, after unlocking the lockable anchors.

[0052] This design also offers the advantage of securing the package in its flat configuration. Indeed, a person cannot then partially open the package by prying apart sections of it without first unlocking the locking latches.

[0053] In a situation where the flat configuration of the package allows for a small storage volume, then this design allowing the package to be secured in its flat configuration is particularly advantageous.

[0054] Other features and advantages of the invention will become more apparent upon reading the following description of a preferred embodiment of the invention, given by way of illustrative and non-limiting example, and the accompanying drawings, among which: [ Fig. 1 ] there figure 1 is a schematic top-view perspective representation of a package according to the invention, in a usage configuration in which a crate of the package is formed and defines a storage volume closed by a lid; Fig. 2 ] there figure 2 is a schematic perspective representation from above of the package according to the invention, in a flat configuration; [ Fig. 3 ] there figure 3 is a schematic side view representation of the package according to the invention, in the flat configuration; [ Fig. 4 ] there figure 4 is a schematic perspective top view of the package according to the invention, in an intermediate state between the usage configuration and the flat configuration, with a detail inset illustrating part of an anchoring shown by a bottom of the package; Fig. 5 ] there figure 5 is a schematic top-view perspective representation of a rear face of a front panel of the parcel crate, the panel incorporating a locking mechanism, including two detail medallions illustrating parts of anchor points; Fig. 6 ] there figure 6 is a schematic top-view representation of the package according to the invention, in an intermediate state between the usage configuration and the flat configuration; [ Fig. 7 ] there figure 7 is a schematic perspective representation, centered on a portion of a second anchoring point presented by the package lid; Fig. 8 ] there figure 8 is a schematic top-view perspective representation of another part of an anchor supported by the bottom of the package, complementary to the part of the anchor illustrated by the figure 7 ; Fig. 9 ] there figure 9 is a schematic cross-sectional representation of the cooperation of the two anchoring parts illustrated by the figures 7 And 8 ; Fig. 10 ] there figure 10 is a partial schematic side view representation of a de-energizing position of the anchors of figures 7 à 9 .

[0055] With reference to figures 1, 2 , 3, 4 And 6 A package 1 according to the invention is shown. Package 1 according to the invention is a foldable package. Package 1 comprises: a background 20; panels.

[0056] The bottom 20 extends between a front end 201 and a rear end 202 along a first axis 200.

[0057] The bottom 20 also includes two lateral ends 203 extending between the front end 201 and the rear end 202.

[0058] Panels 21, 22, 23, and 3 from package 1 are composed of: a front panel 21; a rear panel 22; side panels 23; a cover 3.

[0059] The front panel 21 is pivotally mounted on the front end 201 of the bottom 20.

[0060] The rear panel 22 is pivotally mounted on the rear end 202 of the bottom 20.

[0061] The side panels 23 are mounted pivotally on the lateral ends 203 of the bottom 20.

[0062] According to the present embodiment, the cover 3 is pivotally mounted on the rear panel 22. However, according to a possible embodiment, and through an ad hoc modification of the elements described below, the cover 3 can be pivotally mounted on the front panel 21 of the package 1.

[0063] As mentioned previously, package 1 is foldable. More specifically, package 1 can have different configurations, including a usage configuration and a flat configuration.

[0064] In its usage configuration, package 1 has a box 2 defining a storage volume.

[0065] This box 2 is formed by the joining of the bottom 20, the front panel 21, the rear panel 22 and the side panels 23.

[0066] In this usage configuration, the front panel 21, the rear panel 22, and the side panels 23 form a peripheral rim at the bottom 20. The front panel 21, the rear panel 22, and the side panels 23 are then each in a usage position.

[0067] In this usage configuration illustrated by the figure 1 , lid 3 allows the storage volume to be sealed.

[0068] As explained previously, the cover 3 is pivotally mounted on the rear panel 22. By pivoting the cover 3 backwards, it is possible to access the inside of the storage volume.

[0069] In its flat configuration illustrated by the figures 2 And 3, the front panel 21, the rear panel 22, and the side panels 23 extend substantially parallel to the bottom 20. The front panel 21, the rear panel 22, and the side panels 23 are then each in a folded position (or "storage position").

[0070] Indeed, in this flat configuration of package 1, the side panels 23 are folded down directly against the bottom 20.

[0071] Next, one of the front panel 21 and the rear panel 23 is folded down against the bottom 20 covering the side panels 23, and the other of the front panel 21 and the rear panel 22 is folded back, that is to say pivoted back and positioned in line with the bottom 20.

[0072] In this case, the front panel 21 is in a folded position against the bottom 20, covering the side panels 23, and the rear panel 22 is pivoted backwards, in line with the bottom 20. The rear panel 22 is then in the same plane as the bottom 20.

[0073] Finally, the cover 3 is also folded down against the bottom 20. The cover 3 then covers the side panels 23. According to the present embodiment, the cover 3 also covers the rear panel 22.

[0074] As mentioned previously, the cover 3 is pivotally mounted on the rear panel 22. With reference to figures 2 And 3 , package 1 includes a retaining element 6 by covering one of the front panel 21 and the cover 3.

[0075] In this case, to maintain a front edge 31 of the lid 3 in its folded position against the bottom 20, the front panel 21, as illustrated by the figures 1 à 5 , includes the retaining element 6 by covering, intended to operate a covering of the lid 3 in the flat configuration of the package 1.

[0076] In the flat configuration of package 1, illustrated by the figure 2 and by the figure 3 , the retaining member 6 locks the cover 3 in its folded position against the bottom 20. This retaining member 6 takes the form of a cap extending over, that is to say above the front edge 31 of the cover 3.

[0077] Of course, according to this embodiment the cover 3 must be completely folded down against the bottom 20 before the front panel 21 is in turn completely folded down.

[0078] According to an embodiment not shown, another type of retaining member 6 by covering can take the form of at least one arm mounted movable on one of the front panel 21 and the cover 3. In this case, the arm is positioned under the other of the front panel 21 and the cover 3 in the flat configuration of the package 1. The front panel 21 or the cover 3 carrying the arm cannot then be raised without the other of the front panel 21 or the cover 3 having been raised beforehand, because the arm or arms are captive under this element.

[0079] According to the principle of the invention, the package 1 comprises, in its flat configuration, anchors between the base 20 and at least one of the panels 21, 22, 23, 3 in its folded position against the base 20.

[0080] Each anchor is designed to exert a holding force in its folded position of such panel 21, 22, 23, 3 against the bottom 20.

[0081] In particular, this effort to maintain appears as soon as a force appears tending to move said panel 21, 22, 23, 3 away from its position folded against the background 20.

[0082] These anchorages consist of at least one first anchorage 41, 42 located near the forward end 201 of the bottom 20, and at least one second anchorage 51, 52 located near the rear end 202 of the bottom 20.

[0083] The first anchorages 41, 42 are spaced from the second anchorages 51, 52 along the first axis 200. In other words, the first anchorages 41, 42 are not directly adjacent to the second anchorages 51, 52.

[0084] According to this embodiment, the anchors include: two first anchorages 41, 42, of which a first left anchorage 41 and a first right anchorage 42, which are respectively located near each lateral end 203 of the bottom 20, at the same length along the first axis 200; two second anchorages 51, 52, of which a second left anchorage 51 and a second right anchorage 52, distributed respectively near each lateral end 203 of the bottom 20, at the same length from the first axis 200.

[0085] With reference to the figure 3 Four possible anchoring positions are shown, including but not limited to: a first position P1 and a second position P2 located near the front end 201 of the bottom 20, and a third position P3 as well as a fourth position P4 located near the rear end 202 of the bottom 20.

[0086] In other words, the first two anchors 41, 42 can be located at a position along the first axis 200 corresponding to position P1 or the second position P2, while the second two anchors 51, 52 can be located at a position along the first axis 200 corresponding to the third position P3 or the fourth position P4. As described below, each anchor comprises two parts, a first part presented by a first element of package 1, and a second part presented by a second element of package 1. The first and second parts of each anchor are complementary to each other to achieve the anchoring when package 1 is in its flat configuration.

[0087] According to the present embodiment, the first anchorages 41, 42 comprise a first part represented by the front panel 21, as illustrated by the figure 5 and a second part presented by fund 20, as illustrated by the figure 4 .

[0088] As a result, when the front panel 21 is folded down against the bottom 20, then the first anchors 41, 42 are operational and exert a holding force in its folded position of the front panel 21 against the bottom 20.

[0089] With reference to the figure 4 , the second part 412 of the first left anchorage 41 and the second part 422 of the first right anchorage 42 are formed by anchor points 410 retracted into the side panels 23 in the configuration of use of package 1 and being apparent when the side panels 23 are folded down against the bottom 20.

[0090] With reference to the figure 5 The anchor points 410, formed by rings, are complementary to the first part 411 of the first left anchor point 41 and the first part 421 of the first right anchor point 42 presented by the front panel 21. When the front panel 21 is folded down against the bottom 20, then the anchor points 410 of the second parts 412, 422 go inside the first parts 411, 421. The anchors are thus operational.

[0091] These first anchors 41, 42 are of the clip-on type.

[0092] That is to say, moving package 1 from its usage configuration to its flat configuration allows these anchors to be clipped into place.

[0093] Such clipping is for example achieved by means of a movable hook between a hooking position of the anchor point 410 and a release position.

[0094] This hook may include an elastic return system to maintain it in its latching position, combined with a design, for example an external bevel, that causes the hook to move from its locking position to its release position when the anchor point 410 is inserted into the first portions 411, 421, and to return the hook to its latching position once the insertion is complete. The external bevel may, in particular, form a cam system that causes the hook to retract when the anchor point 410 is inserted, this anchor point pressing on the bevel and thus causing it to retract.

[0095] According to this embodiment and with reference to figures 1, 2 , And 4 , package 1 includes a locking mechanism with two actuators 7.

[0096] These 7 actuators are mobile between: a locking position, notably represented by the figures 1 et 2 , in which, in the flat configuration of package 1, the first anchors 41, 42 are locked; an unlocking position in which the first anchors 41, 42 are unlocked.

[0097] The first anchors 41, 42 are then called “lockable anchors”.

[0098] This locking mechanism includes elastic return means for the actuators 7, tending to return them from their unlocked position to their locked position. These elastic return means may advantageously be the same as the hook return means mentioned previously.

[0099] According to this embodiment, the locking mechanism is also designed to allow the cover 3 to be locked when it closes the storage volume of package 1 in the configuration of use.

[0100] To that end, and with reference to figures 4 And 5, the cover 3 has two locking members 71 and the front panel 21 has two locking elements 72, complementary to the two locking members 71.

[0101] In this case, when package 1 is in its usage configuration and when lid 3 closes the storage compartment, then: in the locking position of the actuators 7, the two locking members 71 are inserted and held captive in the two locking elements 72; and in the unlocking position of the actuators 7, the two locking members 71 are inserted in the two locking elements 72 but are not held captive, the cover 3 being able to be freely pivoted backwards.

[0102] To enable the change of locking state when the actuators 7 are actuation, the locking mechanism can implement a rod or cam system of classic design and known per se.

[0103] With reference to figures 6 à 9 The second anchors 51, 52 are described later.

[0104] As mentioned previously, these second anchorages 51, 52 are located near the rear end 202 of the bottom 20.

[0105] According to this embodiment, the second anchorages 51, 52 consist of a second left anchorage 51 and a second right anchorage 52. These anchorages are located, in particular, at the length corresponding to position P3 illustrated in the figure 3 .

[0106] According to the present embodiment, the second anchorages are made between the base 20 and the cover 3.

[0107] The second anchors 51, 52 are also of the clip-on type. That is to say, when package 1 is in its flat configuration, the second anchors 51, 52 are clipped into place.

[0108] Unlike the first anchors 41, 42, the second anchors 51, 52 are not lockable anchors.

[0109] As mentioned previously, the second anchors 51, 52 include a first part 511, 521 and a second part 512, 522.

[0110] Specifically, the second anchors 51, 52 include: a first part 511, 521 formed by hooked receptacles presented by the lid 3; a second part 512, 522 carried by the bottom 20 in the immediate vicinity of the rear end 202 of the bottom 20.

[0111] These second parts 512, 522 are formed by complementary hooks 5120, 5220 clipping into the hook receptacles formed by the first parts 511, 521 of the second anchors 51, 52.

[0112] The hook receptacles forming the first parts 511, 521 of the second anchors 51, 52 include, in particular, two wings 5110, 5210 that are at least partially elastically deformable. These wings 5110, 5210 guide the hooks 5120, 5220 when the package 1 is in its flat configuration, and in particular when these hooks 5120, 5220 are clipped between the wings 5110, 5210 of the hook receptacles.

[0113] With reference to figures 7 à 10 , the hooks 5120, 5220 and the hook receptacles have a shape designed to achieve a disengagement of the second anchors 51, 52 when a user wishes to unfold package 1 from its flat configuration.

[0114] Specifically, the hooks 5120 and 5220 have a rounded shape and point away from the front end of the base 20, towards a position towards which the lid 3 must be raised when the package 1 is to be unfolded from its flat configuration. The hook receptacles, on the other hand, are open towards the front end of the base 20.

[0115] Also, and more specifically with reference to the figure 10 , pivoting the rear panel 22 backwards, beyond its folded position in line with the bottom, allows the hooks 5120, 5220 to be disengaged from the hook receptacles.

[0116] There figure 10 This illustrates a disarming configuration of the second anchors 51, 52, intermediate between the flat configuration and the usage configuration.

[0117] According to another conceivable design, the second anchors 51, 52 are "force-releaseable" or, in other words, "force-disengageable" anchors. That is to say, to render the second anchors 51, 52 inoperative, it is necessary to exert a pulling force greater than the holding force exerted by the second anchors 51, 52 in the folded position.
