Definitions

• the field of the invention is that of logistics.
• the invention relates to a package, or a means of logistical packaging, that is to say a container, for the transport of objects between two destinations, by means of a package.
• packages such as boxes or cardboard boxes are known.
• packages comprise a box having a bottom and a peripheral rim which together define an internal volume in which the object to be transported is housed.
• the peripheral rim can be movable relative to the bottom of the box. As such, it includes several folding panels on the bottom or in the extension of the bottom of the box.
• the packages also include a movable lid relative to the crate. These lids can in particular adopt a closed position in which the lid closes off the internal volume of the box.
• some packages include retaining means to keep the object to be transported in the box.
• Retaining means which take the form of foam panels integrated into the box and the lid.
• the foam panels can, if necessary, be brought back to the checkout. In other words, the foam panels can be integrated into the body only if their presence is required.
• the foam panels are secured to the bottom of the box, possibly to its peripheral edge, and to the cover.
• This type of retaining means has the major drawback of its thickness, or, in other words, the size it takes up in the internal volume of the box.
• the foam takes up a major part of the internal volume of the box.
• the foam has elastic characteristics so as to form deformable retaining means to match the contour of the object to be transported.
• the same box cannot be used.
• the foam is not properly deformed in contact with the small object, and the latter may then move around in the internal volume of the body at the risk of being damaged.
• Carriers or packaging professionals must therefore have packages of different sizes depending on the size of the objects to be transported.
• the retaining means are in the form of a plastic envelope inside which the object to be transported is slipped, the envelope is then deformed so that its walls come into contact with the object to be transported and hold it in its position.
• the envelopes can be secured to the bottom of the box and their deformation can be carried out for example by heating so as to retract the material, generally a plastic material, so that it stiffens in contact with the object.
• a disadvantage of this solution lies in the fact that the deformation of the envelope, when it is carried out by heating, cannot be carried out by everyone since this technique involves the use of specific heating equipment.
• heating means such as thermal heaters for example, must be used and may require special training so that only professionals can deform the envelope.
• the envelope can also be integral with a tray intended to be housed in the box.
• the object is introduced inside the envelope then, in order to secure and hold the object, the envelope is deformed by folding the edges of the plate, so as to stretch the two walls of the envelope to imprison the object.
• the folded tray can be inserted into the crate and then the movable lid can be closed on the crate.
• the insertion of the object in the envelope does not pose any problem, however the deformation of the plate, in particular the folding of its edges represents a complicated manipulation, even impossible to achieve when the object is bulky and the envelope to be deformed offers a high resistance to deformation.
• the deformation of the envelope can then become time-consuming and put off the professionals who will then make a partial deformation or even offer a larger package generating a higher transport cost for the end consumer.
• Another technique has been developed to meet the need for retaining an object in a package, while offering a simplified mode of operation compared to known techniques.
• the retaining means are integral with the lid and comprise an elastically deformable skin which comes into contact with the object contained in the package, to cover it and hold it against the bottom of the box.
• the flexible skin has a tension applied to the object which could damage said object, especially if it is particularly fragile.
• some objects may have complex shapes for which the elastically deformable skin cannot provide good support.
• the elastically deformable skin cannot provide good support.
• the objects are removed and the package can be reused while the spacer is no longer useful and is then thrown away. This then leads to a risk of pollution, especially if the spacer is not thrown into a recycling circuit or if its recycling is not possible.
• the aim of the invention is in particular to overcome the drawbacks of the prior art.
• the aim of the invention is to propose a solution allowing the wedging of at least one object by automatically adapting to the characteristics of each object, in particular in terms of mechanical strength and in terms of geometry.
• the invention also aims to provide such a solution which makes it possible to create, in the package, zones of different retention intensities.
• the invention also aims to provide such a solution which is simple to implement for a sender of the parcel.
• the invention also aims to provide such a solution which has a small footprint when the package is stored between two uses.

• the presence of the tertiary zone(s) makes it possible to limit the spacing of the elastic central zone with respect to the bottom despite the deformation of the peripheral zone.
• the tertiary zone(s) thus form traction lines from the central zone towards the edges of the elastically deformable skin and therefore towards the bottom of the body.
• An object placed under the elastically deformable skin can therefore be maintained independently of its shape and/or its fragility.
