In general, the advantageous embodiments of each object of the invention are also applicable to the other objects of the invention. As far as possible, each object of the invention can be combined with other objects. The objects of the invention can also be combined with the embodiments of the description, which in addition can be combined with each other.
The means of the invention advantageously allow to impart very good rigidity to the packaging. Not only does the sheath participate in the protection in the shape of a first protective element, but also, the support element has a rigid structure forming a second protective element, providing additional protection in the event that the first protective element would not be sufficient to absorb an impact. The means of the invention also allow the watch to be anchored without clearance in its packaging while guaranteeing easy removal of said watch after opening the packaging. Thus, these means prevent the watch from moving in the packaging. Furthermore, thanks to these means, the packaging can be made of recyclable materials (for example cellulose-based materials), while guaranteeing the same performances in terms of resistance and protection as the conventional packaging. In addition, cellulose-based materials are less brittle than plastics traditionally used for packaging. Finally, the packaging can be lightened thanks to its optimised shape, while having mechanical features comparable to known solutions.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a protective packaging 2 for an object 4, in particular a wristwatch 4 including a watch case to which two wristlet strands are attached. The packaging 2 comprises a sheath 6 and an element 8 for supporting the object 4. The element 8 for supporting the object 4 is slidably mounted in the sheath 6. The element 8 for supporting the object 4 is preferably elongated in shape when the object is a wristwatch 4. The sheath 6 and the support element 8 can have the same length as illustrated in FIG. 1. The support element 8 can have a shape inscribing within a rectangular parallelepiped which is of a shape complementary to the volume delimited by the sheath 6. The sheath 6 may comprise an aperture 10 to see for example the watch head that is to say the watch case 4 without the bracelet being entirely visible. The object is maintained by two elements called holding elements 12A, 12B. FIG. 1 shows the packaging 2 before it is opened.
FIG. 2 shows a packaging 2 after sliding the sheath 6 along a portion of the length of the support element 8. The holding elements 12A, 12B respectively have hollow and preferably curved and/or ribbed shapes having the effect of improving the rigidity of these thin-walled structures (shells) by the hollow body effect and increase in quadratic moments.
FIG. 3 illustrates only the support element 8 in combination with the object 4, that is to say a wristwatch. The two hollow holding elements 12A, 12B are connected to each other by a hinge-type connection 14A, 14B. The removal of the object is facilitated by the pivoting between the two hollow holding elements 12A, 12B.
FIG. 4 shows the support element 6 without the object 4 in an unfolded position. The hinge-type connection 14A, 14B may comprise two hinges 14A, 14B, in order to increase the number of degrees of freedom of the connection between the two hollow holding elements 12A, 12B and in order to better be able to overcome any resistance during releasing of the object from its imprints 16A, 16B, the shape of which corresponds substantially to the outer contour of the watch case. Preferably, the two hollow holding elements 12A, 12B are made integrally. The two hollow holding elements 12A, 12B can be made from moulded cellulose or from Paperfoam® (registered trademark for a family of products whose features are well known). Typically, the packaging can be advantageously directly injection-moulded in a single operation in its open configuration as shown in FIG. 4. Paperfoam® is a material based on a mixture of industrial starch, cellulose fibres, and water injected into the mould during manufacturing. The connection between the two hollow holding elements 12A, 12B can comprise two flexible-type hinges 14A, 14B, the axes of rotation of which are preferably parallel. Each hollow holding element 12A, 12B preferably includes a bottom partition 18A, 18B, a side wall 20A, 20B and two front walls 22A, 22B, 22C, 22D. The two front walls 22A, 22B, 22C, 22D of the hollow holding element 12A, 12B in question can be disposed on either side of the corresponding bottom partition 18A, 18B. The two hinges 14A, 14B are preferably connected to each other by a connecting band 24 which will also be used as a support surface for the case and the wristlet of the watch that the packaging is intended to receive. The band 24 is preferably made integrally with the two hollow holding elements 12A, 12B. Each hinge 14A, 14B may be recessed relative to free edges of the front walls 22A, 22B, 22C, 22D. The latter 22A, 22B, 22C, 22D preferably extend perpendicular to the bottom partition 18A, 18B and are preferably disposed on either side of the hinge 14A, 14B in question. The recess can be comprised between 5% and 30% of the width of each bottom partition 18A, 18B.
In FIG. 4, each side wall 20A, 20B is corrugated and extends between the bottom partition 18A, 18B and a corresponding upper partition 26A, 26B. The imprints 16A, 16B can be defined respectively by central portions of the side walls 20A, 20B facing each other and by portions of the corresponding bottom partitions 18A, 18B. Each upper partition 26A, 26B can comprise flat portions parallel to each other, forming steps. These flat portions are preferably parallel to the corresponding bottom partition 18A, 18B. The upper partitions 26A, 26B, and the bottom partitions 18A, 18B as well as the side walls 20A, 20B respectively form two beam structures having very good flexural rigidity. Each upper partition 26A, 26B can have a width comprised between 5% and 60% of the width of the hollow holding element 12A, 12B.
The two hollow holding elements 12A, 12B preferably have a symmetry called mirror symmetry and constitute two “halves” of the support element 8, with the exception of the imprints or notches formed in the upper walls 26A, 26B allowing to receive lateral portions of the watch case 4 including, for example, one with a crown and the other without a crown. The size and shape of the notches can naturally vary depending on the shape of the watch that the packaging is intended to receive.
The embodiment according to FIGS. 1-4 has two hinges 14A, 14B. In an alternative embodiment not shown, the packaging 2 can comprise a single flexible hinge.
FIGS. 5-10 show another embodiment of a packaging according to the invention. This embodiment incorporates the features of the embodiment according to FIGS. 1-4 and further comprises additional means to improve among others the rigidity and modularity of the packaging 2.
FIG. 5 shows a schematic perspective view of the other embodiment of a packaging 2 according to the invention containing an object 4.
As illustrated in FIGS. 6, 7, 8a and 8b, the support element 8 includes means 28 for adjusting the height of the watch case 4 in the packaging 2, disposed at the connecting band 24. The height adjustment means 28 may include a flexible blade 28.1, the two ends of which are integral with the connecting band 24 and an intermediate part of which between its ends is curved in the direction away from the connecting band 24. Preferably, the flexible blade 28.1 is made integrally with the connecting band 24. The flexible blade 28.1 is formed by two parallel slots 28.2 formed on the connecting band 24, which has a curvature at its central part. These means allow to receive watch cases having different thicknesses.
In FIGS. 6, 7, 8a and 8b, the imprints 16A, 16B may comprise adaptive means 30 allowing to receive watch heads whose cases respectively have different diameters. The side walls 20A, 20B can respectively comprise flexible strips 30.1. Each flexible strip 30.1 has two ends integral with its side wall 20A, 20B and an intermediate part between its ends. Each intermediate part is a curved strip, the profile of which is adapted to enclose the watch case 4. Preferably, each flexible strip 30.1 is made integrally with its side wall 20A, 20B. Each flexible strip may be formed by two parallel interstices (slots) 30.2 provided on its side wall 20A, 20B, preferably at the junctions with the corresponding bottom partition 18A, 18B and the corresponding upper wall 26A, 26B.
As illustrated in FIGS. 6, 7, 8a, 8b, 9a and 9b, the (hollow) holding elements 12A, 12B can be held in the closed position by locking means 32. The locking means 32 comprise at least one hook 32.1 arranged on one of the (hollow) holding elements 12A, 12B and disposed at the corresponding upper partition 26A, 26B. The or each hook 32.1 is of complementary shape to an aperture 32.2 formed on the other upper partition 26A, 26B. The or each hook 32.1 (male part) and the complementary aperture 32.2 (female part) can constitute an elastic snap-fit. Preferably, the or each hook 32.1 is integral with the corresponding upper partition 26A, 26B. The or each hook 32.1 can be carried by an elastic arm connected to the corresponding upper partition 26A, 26B.
In FIGS. 6, 7, 8a, 8b, 9a, 9b and 10, the support element 8 comprises shear deformation limiting means 34 provided at the front walls 22A, 22B, 22C, 22D. The shear deformation limiting means 34 can comprise tabs 34.1 and complementary grooves 34.2, the tabs 34.1 being adapted to engage in complementary grooves 34.2. Each tab 34.1 includes a rounded end facilitating the engagement of each tab 34.1 into the corresponding groove 34.2 when closing the support element 8. When the support element 8 is in the closed position, the interlocking between each tab 34.1 and its groove 34.2 prevent relative movement between the wafers (that is to say the free edges) vis-à-vis the respective front walls 22A, 22B, 22C, 22D. Preferably, the grooves 34.2 are formed on the external or internal faces of the front walls 22A, 22B, 22C, 22D.
