Description

[0001] The field of invention is logistics.

[0002] More specifically, the invention relates to a package for the transport of objects between two destinations, the package incorporating means for retaining objects.

[0003] To transport an object safely and securely, packages such as boxes or cartons are known.

[0004] Generally speaking, parcels consist of a box with a base and a peripheral rim which together define an internal volume in which the object to be transported is housed.

[0005] The peripheral rim can be movable relative to the bottom of the crate. As such, it includes several panels that fold down onto the bottom or extend from the bottom of the crate.

[0006] The packages also include a lid that moves relative to the crate. These lids can, in particular, be in a closed position in which the lid seals the internal volume of the crate.

[0007] In order to protect the items being transported, some packages include restraints to hold the item to be transported in position within the crate.

[0008] There are known restraint systems that take the form of foam panels integrated into the crate and lid. These foam panels can be attached to the crate if necessary. In other words, the foam panels can only be integrated into the crate if their presence is required.

[0009] More specifically, the foam panels are attached to the bottom of the box, possibly to its peripheral rim, and to the lid.

[0010] The object to be transported is then inserted into the internal volume so as to come into contact with the foam and to be blocked by the foam of the bottom and the foam of the lid.

[0011] The major drawback of this type of restraint system is its thickness, or, in other words, the bulk it occupies in the internal volume of the crate.

[0012] Indeed, the foam occupies a major part of the internal volume of the crate. However, the foam has elastic properties that allow it to form deformable retaining devices to conform to the shape of the object being transported.

[0013] However, depending on the size of the item, several packages may be required.

[0014] For example, the same box cannot be used for a large item and a small item. In the case of the small item, if a box or package designed for a large item is used, the foam will not be properly deformed upon contact with the small item, and the latter may then move within the internal volume of the box, risking damage.

[0015] Conversely, if a large object is placed inside a box designed to hold a small object, the package may become unusable due to insufficient space. The lid cannot be properly closed to completely seal the box's interior. Consequently, the object is not adequately protected and is visible to anyone carrying the package, potentially leading to theft.

[0016] Carriers or packaging professionals must, therefore, have packages of different sizes depending on the size of the items to be transported.

[0017] According to another known technique, the restraints take the form of a plastic envelope into which the object to be transported is slid; the envelope is then deformed so that its walls come into contact with the object to be transported and hold it in position.

[0018] According to one type, the envelopes can be attached to the bottom of the box and their deformation can be achieved, for example, by heating so as to shrink the material, generally a plastic material, so that it stiffens upon contact with the object.

[0019] One drawback of this solution is that the deformation of the envelope, when carried out by heating, cannot be done by everyone since this technique involves the use of specific heating equipment.

[0020] Indeed, heating methods, such as heat guns for example, must be used and may require special training so that only professionals can deform the envelope.

[0021] Furthermore, when the envelope is attached to the bottom of the box, this can present a major drawback for the integrity of the box, especially if it is made of cardboard, as excessive heat can destroy the cardboard by burning it.

[0022] Furthermore, inserting the item to be transported into the envelope may prove difficult, or even impossible.

[0023] This is particularly true if the object to be transported is inserted into the envelope once the crate is in shape, i.e. once the internal volume is defined, the peripheral rim of the crate forming a major obstacle to the insertion of the object into the envelope.

[0024] To overcome this, it may be necessary, firstly, to insert the object into the envelope, then to form the box, and finally to deform the envelope.

[0025] This represents a significant amount of handling time which can be detrimental to professionals and also impossible for individuals to carry out, particularly for deforming the envelope or shaping the box.

[0026] In a second type, the envelope can also be attached to a tray designed to be placed inside the crate. In this case, the object is placed inside the envelope, and then, to secure and hold the object in place, the envelope is deformed by folding the edges of the tray, thus stretching the two walls of the envelope to enclose the object. Once this is done, the folded tray can be inserted into the crate, and then the hinged lid can be closed.

[0027] These restraint methods also have some drawbacks.

[0028] Indeed, inserting the item into the envelope is straightforward; however, deforming the envelope, particularly folding its edges, is a complicated, even impossible, process, especially when the item is large and the envelope offers significant resistance to deformation. Deforming the envelope can then become time-consuming and discourage professionals, who may then opt for partial deformation or even offer a larger package, resulting in higher shipping costs for the end consumer.

[0029] In addition, this requires the storage of the crate, lid and retaining devices, which represents a total detrimental bulk and therefore an additional cost that is often passed on to the end customer.

[0030] Finally, another solution described in patent document published under number FR 3 102 162 describes a package, according to the preamble of claim 1, for transporting objects, comprising a crate and object retention means attached to the crate and defining an object reception volume. The retention means have an access opening to the reception volume.

[0031] The restraint system consists of a bag attached to the bottom, with the access opening facing away from the bottom.

[0032] This package also includes actuation means configured to change the size of the access opening, from a widened configuration, allowing access to the receiving volume, to a narrowed configuration, preventing access to the receiving volume and in which the restraint means envelop the object(s) located in the receiving volume to immobilize them in the crate, or vice versa.

[0033] The actuation means take the form of a drawstring threaded at least partially through loops in the bag, with stop means to maintain the opening in its tightened configuration.

[0034] However, this package has one major drawback.

[0035] Indeed, the flexibility of the bag makes it difficult to use when the object to be transported is bulky and / or heavy and must be carried with two hands.

[0036] In this case, the user must place the object to find a solution to maintain the opening in its expanded configuration in order to be able to insert the object into the receiving volume, with both hands.

[0037] One solution to this problem would be to provide the package with a bag large enough to overflow from the box so that the item can be inserted without having to handle the bag.

[0038] However, using a large bag can cause it to get caught outside the box and tear if the user of the package is not careful and pulls on the bag too violently.

[0039] In addition, a large bag requires a large drawstring which, when the opening is in its tightened configuration, must be wound up in order to be preserved and stored in the package.

[0040] The use of such a package therefore requires a certain amount of care to avoid prematurely damaging the restraint and actuation means.

[0041] The invention aims in particular to overcome the drawbacks of the prior art.

[0042] More specifically, the invention aims to provide a package equipped with means for retaining objects that is foldable and simpler to use than prior art solutions.

[0043] The invention also aims to provide such a package that is lightweight.

[0044] The invention also aims to provide such a package which has a small footprint when folded for storage.

[0045] These objectives, as well as others that will emerge subsequently, are achieved through the invention, which relates to a package for transporting objects, comprising: a box; object retention means, integral with the box and defining an object reception volume, the retention means having an access opening to the reception volume; actuation means configured to change the size of the access opening, from a widened configuration, allowing access to the reception volume, to a narrowed configuration, preventing access to the reception volume and in which the retention means enclose the object(s) located in the reception volume to immobilize them in the box, or vice versa, characterized in that the package also includes return means configured to maintain the access opening in its expanded configuration, the actuation means acting against the return means in the compressed configuration of the access opening.

[0046] Thanks to the presence of the return means, the opening can be maintained in its enlarged configuration to facilitate the insertion of objects into the receiving volume or, conversely, facilitate the removal of objects from the receiving volume.

[0047] Thus, the user can use both hands to manipulate objects without worrying about opening access to the receiving volume, which limits the risk of damaging objects.

[0048] Furthermore, the fact that the actuation means act against the return means ensures an automatic opening of the receiving volume when the actuation means are used to allow the access opening to switch from its narrowed configuration to its widened configuration.

[0049] In other words, the transition of the access opening from its expanded configuration to its restricted configuration constrains the recall means which then tend to recover an unconstrained, or almost unconstrained, position when the access opening is in its expanded configuration.

[0050] According to one advantageous aspect, the means of actuation include: a cord passing through slots made in the retaining means near the opening, and a clamping member cooperating with the cord to hold it in the form of a loop.

[0051] Such means of actuation are simple to implement.

[0052] Indeed, a user only needs to hold the tightening mechanism with one hand and pull on the cord with the other hand to reduce the size of the loop and cause the access opening to move from its widened configuration to its tighter configuration.

[0053] Switching the access opening from its narrowed configuration to its widened configuration is just as simple, since the user only has to manipulate the clamping element with one hand and then let the cord pass through the clamping element under the action of the return means which tend to widen the access opening and thus enlarge the loop.

[0054] The user can use their second hand to hold the cord lightly to prevent it from moving too quickly and becoming dangerous.

[0055] Another advantage is that the means of restraint include: a cover attached to the bottom of the case by one end and whose second end opposite the first end forms the access opening, and at least three elastically deformable rods attached to the bottom and the cover, the return means being formed by the rods which tend to bend when the access opening is in a narrowed configuration, and tend to recover a straight position when the access opening is in its widened configuration.

[0056] Such restraint methods are easy to implement and offer good protection for objects since the cover can cover the entirety of the object(s) received in the receiving volume.

[0057] In addition, the cover can wrap around the objects in order to press them against the bottom of the crate and thus immobilize them.

[0058] According to a first advantageous embodiment, the box has a rectangular parallelepiped shape, and the retaining means comprise at least four elastically deformable rods, each rod being located in a corner of the box.

[0059] The presence of rods in the corners of the crate ensures full access to the receiving volume, as the cover is pulled towards each corner of the crate. Consequently, the cover follows the contours of the crate, providing an opening roughly equal to the size of the crate.

[0060] According to a variant of the first embodiment, the box has a rectangular parallelepiped shape, and the retaining means comprise at least four elastically deformable rods, each rod being located on an edge of the box.

[0061] Positioning the rods on the edges of the case promotes the creation of areas of minimal deformation of the cover, these areas being located in the corners of the case.

[0062] These slightly deformed areas make it possible to achieve a first level of securing of the objects in the receiving volume, which further ensures that the objects are held in the package during transport.

[0063] According to a second advantageous embodiment, the restraint means are in the form of panels each mounted on rotation on a bottom of the crate by a first edge and of which a second edge opposite to the first edge forms the access opening.

[0064] The use of panels ensures ease of handling of restraint devices.

[0065] Indeed, the panels ensure that the access opening remains in an expanded configuration on each side of the case, unlike the cover which could stretch.

[0066] According to an advantageous aspect, each panel comprises an elastically deformable frame and a fabric stretched over the frame, the lifting means being formed by the elastically deformable frame.

[0067] This panel architecture allows for easy use and simple assembly of the restraint systems.

[0068] The panels are sufficient on their own to ensure the passage of the access opening from its narrowed position to its widened position.

[0069] According to another advantageous aspect, the canvas of each panel is formed by an elastically deformable fabric.

[0070] The use of an elastically deformable fabric allows the panel to adapt to the shapes of the object in order to increase the retaining power of the panels.

[0071] Furthermore, the elastic fabric allows a clamping force to be applied to the object in order to ensure that it is immobilized against the bottom of the box.

[0072] Another advantage is that each panel is made from a non-deformable material.

[0073] The use of a non-deformable material allows the package to be dedicated to a specific use.

[0074] Indeed, the panels may, for example, have a counter-shape designed to receive part of an object to be transported, in order to ensure its total immobilization without exerting any effort on said object.

[0075] According to another advantageous aspect, the return means also include springs interposed between a bottom of the case and the panels.

[0076] The use of springs ensures that the panels open and therefore the access opening moves from its narrowed configuration to its widened configuration.

[0077] This makes using the package easier.

[0078] In an advantageous case, the means of return also include at least three elastically deformable rods attached to the bottom.

[0079] The combination of springs or reinforcement with rods offers the advantage of a double return in the widened access opening configuration. Therefore, if the springs or elastic reinforcement lose their elasticity, the rods ensure the widened access opening.

[0080] According to another advantageous aspect, the crate has a rectangular parallelepiped shape, and the restraint means include four panels each extending along one side of the crate.

[0081] Thanks to the presence of four panels, and their positioning, it is possible to ensure contact between each of the panels and the object to be transported, and therefore to ensure the immobilization of the object on the bottom of the crate.

[0082] Other features and advantages of the invention will become more apparent upon reading the following description of preferred embodiments of the invention, given by way of illustrative and non-limiting examples, and the accompanying drawings, among which: [ Fig. 1 ] there figure 1 is a schematic representation of a package according to the invention, the package comprising means for retaining an object, defining a volume for receiving objects, the retaining means having an access opening to the receiving volume that can evolve from an expanded configuration to a narrowed configuration, and vice versa, the package also comprising return means tending to position the access opening in its expanded configuration; Fig. 2 ] there figure 2 is a schematic representation of a first embodiment of the means for retaining the package according to the invention, the access opening being in its enlarged configuration; [ Fig. 3 ] there figure 3 is a schematic representation of the first embodiment of the package retention means according to the invention, the access opening being in its narrowed configuration; [ Fig. 4 ] there figure 4 is a schematic representation of a second embodiment of the package retention means according to the invention, the access opening being in its enlarged configuration; [ Fig. 5 ] there figure 5 is a schematic representation of the second embodiment of the package retention means according to the invention, the access opening being in its narrowed configuration; [ Fig. 6 ] there figure 6 is a schematic representation of a third embodiment of the means for retaining the package according to the invention, the access opening being in its enlarged configuration, [ Fig. 7 ] there figure 7 is a schematic representation of one embodiment of the means for recalling the package according to the invention.

[0083] There figure 1 illustrates a package 1 according to the invention.

[0084] Package 1 typically includes a crate 2 which can be closed by a lid 3.

[0085] The lid 3 can adopt a closed position for the case 2, as illustrated by the figure 1 , to close an internal volume of the crate 2, and an opening position of the crate 2 allowing access to the inside of the crate, in particular for loading or unloading at least one object O.

[0086] The box 2 comprises a base 21 and a peripheral rim 22 extending from the base 22.

[0087] To ensure the protection of objects O intended to be transported in package 1, package 1 includes means of restraint 4 of objects O.

[0088] The restraint means 4 define a volume for receiving objects O.

[0089] The restraint means 4 present an access opening 41 to the receiving volume.

[0090] Thanks to this access opening 41, objects O can be introduced into the receiving volume or extracted from the receiving volume.

[0091] As explained below, access opening 41 has a size that can change from an expanded configuration, as illustrated by the figures 2 4 And 6 , towards a more compact configuration, as illustrated by the figures 3 And 5 , or vice versa.

[0092] In the expanded configuration of access opening 41, objects O can be introduced into or extracted from package 1.

[0093] In contrast, in the narrow configuration of the access opening 41, objects O contained in the crate 2 of package 1 are intended to be immobilized by the restraint means 4 to allow their protection during the transport of package 1 from a first location to a second location.

[0094] By protection, it is understood that by being immobilized, the object(s) O are protected against sudden movements within the internal volume of the crate 2 during its handling.

[0095] To change the size of the access opening 41, package 1 includes actuation means 5 described below.

[0096] The actuation means 5 include, as illustrated by the figures 2 à 6 a cord 51 and a clamping member 52 cooperating with the cord 51 to hold it in the form of a loop. The clamping member comprises a body through which the cord 51 passes, the body housing a movable member that can adopt a locking position in which it locks the cord 51 inside the body, and a release position in which it allows the cord 51 to slide freely within the body.

[0097] The cord 51 is intended to pass through openings 46 made in the restraint means 4, near the access opening 41.

[0098] Package 1 also includes recall means configured to maintain access opening 41 in its expanded configuration.

[0099] According to a first embodiment illustrated by the figures 2 And 3 The means of restraint include: a cover 42 attached to the base 21 by a first end 421 and whose second end opposite 422 to the first end 421 forms the access opening 41, and at least 3 elastically deformable rods attached to the base 21 and the cover 42.

[0100] According to this first embodiment, the return means are formed by the rods 43 which tend to bend when the access opening 41 is in a narrowed configuration, as illustrated in the figure 3 , and tend to return to an upright position when the access opening 41 is in its enlarged configuration, as illustrated by the figure 2 .

[0101] According to this first embodiment, the lights 46 are made on the rods 43. More precisely, the lights 46 take the form of rings located at one end of the rods 43, opposite a junction end by which the rods 43 are secured to the bottom 21 of the box 2.

[0102] Thus, by decreasing the size of the loop of the actuation means 5, the opening of each of the rods 43 tends to move closer to the other openings 46, thereby reducing the size of the access opening 41, which then changes from its enlarged configuration, as illustrated by the figure 2 , to its compact configuration, as illustrated by the figure 3 .

[0103] This then causes the rods 43 to be pressed against the object(s) O located in the receiving volume, in order to ensure their immobilization.

[0104] The cover 42 can, for example, be made of an elastic material, designed to conform to the shapes of the objects O located in the receiving volume.

[0105] According to the embodiment illustrated by the figures 2 And 3 , box 2 has a rectangular parallelepiped shape and base 21 has a rectangular shape.

[0106] In this case, the restraint means 4 comprise at least four elastically deformable rods 43, each rod 43 being located in a corner of the box 2.

[0107] Alternatively, each stem is located on an edge of box 2.

[0108] According to another embodiment not shown in the figures, the retaining means 4 comprise more than four rods 43, of which four rods 43 are located in the corners of the box 2, the other rods 43 being located along the edges of the box 2.

[0109] According to a second embodiment illustrated by the figures 4 And 5 , the restraint means 4 include panels 45.

[0110] According to the second embodiment illustrated by the figures 4 And 5 , box 2 has a rectangular parallelepiped shape, and base 21 has a rectangular shape.

[0111] In this case, there are four panels 45, each extending along one side of box 2.

[0112] The panels 45 are rotationally mounted on the bottom 21 by a first edge 451 and have a second edge 452, opposite the first edge 451, forming the access opening 41 of the retaining means 4 and having the lights 46 through which the cord 51 of the clamping means 5 is intended to pass.

[0113] Each panel 45 comprises an elastically deformable frame 453, and a canvas 454 stretched over the frame 453.

[0114] In this case, the means of return are formed by the 453 reinforcement.

[0115] Each fabric 454 is, for example, formed by an elastic fabric stretched over the frame 453. An elastic fabric is considered to be a tightly woven fabric, such as, for example, twill, taffeta or satin, or a loosely woven fabric, such as, for example, net.

[0116] According to a variant of the second embodiment, each panel 45 is made of a non-deformable material.

[0117] In this case, the return means comprise springs 6 interposed between each panel 45 and the bottom 21 of the case 2, as illustrated by the figure 7 .

[0118] According to a third embodiment illustrated by the figure 6 , the restraint means 4 are a combination of the first embodiment and the second embodiment.

[0119] For this purpose, the restraint means 4 include rods 43 and panels 45.

[0120] According to this third embodiment, the return means are formed by the rods 43 which tend to bend when the access opening 41 is in its narrowed configuration, and tend to return to a straight position when the access opening 41 is in its widened configuration, as illustrated by the figure 6 .

[0121] Alternatively, the return means may include, in addition to the rods 43, springs 6 interposed between each panel 45 and the bottom 21 of the box 2, as illustrated by the figure 7 , or be formed by the 453 reinforcement which is then elastically deformable.

[0122] According to this third embodiment, the lights 46 are made on the rods 43 and on the panels 45.

[0123] More specifically, the lights 46 take the form of rings located at one end of the rods 43, opposite a junction end by which the rods 43 are secured to the bottom 21 of the box 2, and of openings made in the panels 45.

[0124] This variant offers the advantage of a double recall in the expanded configuration of access opening 41.

[0125] Indeed, the springs 6 and the rods 43 allow, by their elasticity, to cause the enlargement of the access opening 41 to its enlarged configuration.

[0126] In use, when a user wishes to house an object O in the package 1, he manipulates the actuation means 5 to increase the size of the loop and position the access opening 41 of the retention means 4 in the enlarged configuration.

[0127] This allows access to the receiving volume to introduce an object O into package 1.

[0128] When object O is introduced, the user again manipulates the actuation means 5 to reduce the size of the loop of cord 52.

[0129] This then causes access opening 41 to switch from its expanded configuration to its restricted configuration.

[0130] It follows that the restraint means 4 come against the object(s) O located in the receiving volume to immobilize them relative to the bottom 21 of the container 2. More specifically, the rods 43, the supports 453, and / or the springs 6 bend under the effect of the reduction in size of the access opening 41, which causes the openings 46 to move closer together. Consequently, the cover 42 or the panels 45 come into contact, at least partially, with the object(s) O to immobilize them against the bottom 21.

[0131] In the case of the cover 42, the transition from the access opening 41 to its narrowed configuration causes the object(s) O to be enveloped by the cover 42.

[0132] According to the first embodiment, the object(s) O are held immobilized on the base 21 of the crate 2 by means of the rods 43 and, where applicable, the cover 42. According to the second embodiment, it is the panels 45 that hold the object(s) O immobilized on the base 21 of the crate 2. Finally, according to the third embodiment, the object(s) O are held immobilized on the base 21 of the crate 2 by means of the panels 45 and the rods 43.

[0133] The presence of the clamping element 52 of the actuation means 5 allows the access opening 41 to be maintained in the tightened configuration and thus the object(s) O to be kept immobilized on the bottom 21 of the box 2.

[0134] The user can then close package 1 by positioning lid 3 in its closed position.

[0135] Conversely, when a user wishes to extract an object O from the package 1, they open the lid 3 and then manipulate the actuation means 5 to position the access opening 41 in its expanded configuration from its compressed configuration. This then causes the retention means 4 to release and allows, via the expanded access opening 41, the extraction of the object O located in the receiving volume.

[0136] By moving from its narrowed configuration to its widened configuration, the access opening 41 allows the restraint means 4 to be relaxed.

[0137] According to the first embodiment, the rods 43 tend to return to their upright position, causing the cover 42 to move outward and widen. According to the second embodiment, the panels 45 tend to return to a substantially vertical position, allowing them to move outward from the object(s) O and thus enabling the access opening 41 to move from its narrowed to its widened configuration. According to the third embodiment, the movement of the access opening 41 from its narrowed to its widened configuration is caused by the rods 43 tending to return to their upright position, causing the cover 42 to move outward and widen, and by the panels 45 tending to return to a substantially vertical position, allowing them to move outward from the object(s) O.

[0138] Package 1, which has just been described, allows for manual securing of the objects O contained in package 1, without significantly increasing the weight of package 1, thus improving its ease of handling.

[0139] The restraint means 4 are easy to use and implement, and package 1 is easy to use.

[0140] Furthermore, the access opening 41 is maintained in an expanded configuration by the recall means, which ensures ease of insertion of objects O into the receiving volume or, conversely, ease of removal of objects contained outside the receiving volume.

[0141] Furthermore, the mere manipulation of the actuation means 5 proves quick and easy for a user and promotes the retention and protection of the objects O in the package 1.

[0142] Finally, thanks to the elasticity of the retaining means, package 1 can be folded and have a small footprint, facilitating its storage when not in use.
