• This structure 8 is obtained for each box 3 by the connection, along a pre-fold 9, of an external side panel 10 with an intermediate panel 11, the latter being itself connected, along a pre-fold 12, to an internal side panel 13.

• Means for maintaining the closure panel 6 in its cover function have been provided. These are two attachment tabs 39 projecting from the closure panel 6, more precisely from its two opposite edges 40 which are perpendicular to the pre-fold 38 connecting it to the flap 5. These attachment tabs 39, delimited each by a pre-fold 41 in alignment with the edge 40 of the closure panel 6, are able to cooperate with two notches 42 each formed on one of the intermediate panels 11.

• the formation of the packaging 1 for spectacle lens 18 from the blank 34 described is done simply by gluing each fixing flap 53 to the corresponding edge 7 of the bottom panel 2 (shaded area in FIG. 9) so as to juxtapose the pre-fold 52 joining the internal side panel 13 to the fixing flaps 53 and the pre-fold 14 joining the external side panel 10 to the bottom panel 2.
• the external side panel 10, the intermediate panel 11 and the internal side panel 13 thus form a triangular profile 8.
• FIG. 9 represents the blank 34 before bonding
• FIG. 7 represents the blank 34 once this bonding operation has been carried out, the boxes 3 then being formed (they are seen from above in FIG. 9) and a simple folding operation for placing the boxes in the raised position 3 makes it possible to obtain a package 1 ready for use, as visible in FIG. 1.
• the outline of the blank 34 is first cut, the various notches and cuts also being carried out, the pre-folds are made and the gluing of the fixing flaps 53 on the edge 7 corresponding is carried out, keeping the boxes 3 folded along their pre-fold 54, so as to obtain the flat blank of FIG. 10.

• FIG. 6 is a schematic representation in which the external side panel 10 of one of the boxes 3 is seen in transparency so as to make visible the behavior of the wedging tongues 20, 21 during the insertion of the glass 18 into the openings 15
• the curvature of the contour of the glass 18 has the effect of pushing the two central tongues 20 further inward of the box 3 than the two lateral tongues 21, this being made possible by the fact that these wedging tongues 20, 21 are without attachment at the edge 16 of the opening 15 flush with the bottom panel 2.
• Figures 4 and 5 show the position of the tongues 20, 21 relative to the glass 18 in a view along the longitudinal axis of the boxes 3. It appears that the central wedging tongues 20 of the boxes 3 are wedging the glass 18 according to one of its diameters, by adapting to the circumference and profile of the contour of the glass 18. The lateral wedging tongues 21, for their part, also come to be positioned by adapting to the curvature of the glass 18 and exert a wedging by the opposite pressure of each pair of corresponding tongues 20, 21 vis-a-vis on each box 3.
• the lateral tabs 21 also exert a retention of the glass 18 in the event of translation in the longitudinal direction of the boxes 3 since their edges lateral come into abutment laterally against the contour of the glass 18, at the point where it sinks deeper towards the central tabs 20.
• the setting of the glass 18 is therefore ensured by the joint pressure of each pair of tongues 20, 21 opposite on either side of its diameter, whether central or lateral, as well as by the pressure of the four lateral tongues 21 forming a cage of four points, adaptable to the contour of the glass 18 and preventing it from sliding laterally.
• the function of pressurizing the glass 18 by the pairs of tongues 20, 21 opposite on each box 3 is jointly ensured by elastic properties of the material of the tongues 20, 21 as well as by the configuration of the boxes 3 in triangular profile 8 allowing the free end 26 of a tongue, when it is biased towards the inside of the box 3, to go up along the internal wall of the external side panel 10 and possibly to brace against it (see FIGS. 4 and 5), the pre folds 25 distributed along the tongue 20; 21 promoting this behavior.
• packaging described here can also be used to package and wedge an object with a circular contour other than a non-contoured spectacle lens, for example another type of optical lens.
