The dimensions of the lid are about the same as those of the base, and it has tongues (39, 46) on its edges to enage with slots (42) in the upper edges of the side walls and the base to fasten it in the closed position.

Description

L'invention concerne un emballage de protection et de calage convenant au conditionnement d'objets à contour circulaire, et plus spécifiquement à un objet de dimension et de forme comparable à celle d'un verre de lunettes fini ou semi-fini.The invention relates to a protective and cushioning packaging suitable for packaging objects with a circular contour, and more specifically to an object of size and shape comparable to that of a finished or semi-finished spectacle lens.

Un verre "semi-fini" est un verre de lunettes dont seule la face convexe est finie (usinée) en production de série.A "semi-finished" glass is a spectacle lens whose only convex surface is finished (machined) in series production.

Un tel verre est expédié par le fabricant vers un "laboratoire de prescription" qui se charge d'usiner la face concave en fonction des besoins du porteur.Such a glass is sent by the manufacturer to a "prescription laboratory" which is responsible for machining the concave face according to the needs of the wearer.

Lors de l'expédition de ce verre, il est primordial de bien caler le verre pour protéger cette face finie en lui évitant tout contact, en particulier dans le cas d'un verre en matériau organique qui a la particularité de se rayer très facilement.When shipping this glass, it is essential to stall the glass to protect this finished face by avoiding contact, especially in the case of a glass organic material that has the distinction of scratching very easily.

Dans le cas d'un verre fini, en revanche, les deux faces, concave et convexe, sont finies en production de série.In the case of a finished glass, on the other hand, both sides, concave and convex, are finished in series production.

Ce verre est expédié par le fabricant à l'opticien qui le déborde (détoure) en fonction de la forme de la monture sélectionnée par le porteur et de paramètres morphologiques propres à ce porteur (écart pupillaire, position des pupilles par rapport aux cercles de la monture).This glass is sent by the manufacturer to the optician who overflows (detour) depending on the shape of the frame selected by the wearer and morphological parameters specific to the wearer (pupillary distance, position of the pupils in relation to the circles of the mount).

Là aussi, il est important de protéger les faces du verre, dans la mesure où elles sont finies (c'est-à-dire usinées et le plus souvent munies de couches de traitements, par exemple, anti-abrasion, anti-reflets ou anti-salissures).Again, it is important to protect the faces of the glass, to the extent that they are finished (that is to say machined and most often provided with layers of treatments, for example, anti-abrasion, anti-reflective or anti-fouling).

Des emballages destinés à assurer un tel conditionnement sont connus de l'art antérieur.Packages intended to ensure such packaging are known from the prior art.

La demande de brevet français N° FR-2 703 654 décrit un emballage-tiroir pour verres de lunettes constitué d'une enveloppe externe et d'un réceptacle, ce dernier comportant un panneau de fond, et deux rebords en caisson articulés en parallélogramme déformable, une découpe étant pratiquée dans chaque rebord en caisson, pour l'insertion au moins partielle du verre de lunettes.French patent application N ° FR-2 703 654 discloses a drawer-case for eyeglass lenses consisting of an outer envelope and a receptacle, the latter comprising a bottom panel, and two deformable parallelogram-shaped box edges, a cutout being made in each box-edge, for the at least partial insertion of the spectacle lens.

Le réceptacle de cet emballage-tiroir reçoit le verre de lunettes sur son panneau de fond et dans les découpes précitées, puis est inséré dans l'enveloppe externe, le tout formant une boîte apte à être transportée.The receptacle of this packaging-drawer receives the spectacle lens on its bottom panel and in the aforementioned cutouts, and is inserted into the outer casing, the whole forming a box suitable for transport.

Le document DE-A-2636454 divulgue un emballage selon le préambule de la revendication 1.The document DE-A-2636454 discloses a package according to the preamble of claim 1.

Ces emballages donnent satisfaction quant à la réalisation de la fonction pour laquelle ils sont prévus.These packs are satisfactory in achieving the function for which they are provided.

L'invention vise néanmoins à les améliorer, notamment en ce qui concerne le calage du verre.The invention is nevertheless intended to improve them, particularly as regards the setting of the glass.

A cet effet et selon un premier objet, l'invention porte sur un emballage de protection et de calage convenant au conditionnement d'un objet à contour circulaire tel qu'un verre de lunette, cet emballage comportant :

  • un panneau de fond ;
  • deux caissons comportant chacun un panneau latéral externe et un panneau latéral interne qui comporte une ouverture pour insertion au moins partielle de l'objet, chaque caisson étant rattaché par une articulation au panneau de fond le long d'un respectif de deux bords opposés, chaque caisson étant adapté à admettre une position abattue dans laquelle le panneau latéral externe s'étend dans le prolongement du panneau de fond, et une position relevée dans laquelle le panneau latéral externe est dressé par rapport au panneau de fond ;
  • deux rabats rattaché chacun par une articulation au panneau de fond le long d'un respectif de deux bords opposés, adjacents aux caissons, chaque rabat étant adapté à admettre une position abattue dans laquelle il s'étend dans le prolongement du panneau de fond, et une position relevée dans laquelle le rabat est dressé par rapport au panneau de fond, contre les extrémités longitudinales des caissons ;
  • des moyens pour maintenir les caissons et les rabats en position relevée ; caractérisé en ce que, pour chaque caisson, ledit panneau latéral externe comporte une première extrémité reliée par une articulation au panneau de fond, une seconde extrémité reliée par une articulation à une première extrémité d'un panneau intermédiaire, celui-ci comportant également une seconde extrémité reliée par une articulation à une première extrémité dudit panneau latéral interne, celui-ci comportant également une seconde extrémité reliée par une articulation au panneau de fond, le long de l'articulation entre la première extrémité du panneau latéral externe et le panneau de fond; et en ce que au moins deux languettes de calage sont disposées dans l'ouverture en étant rattachées au panneau latéral interne exclusivement par une extrémité opposée au panneau de fond, lesdites languettes étant juxtaposées.
For this purpose and according to a first object, the invention relates to a protective and cushioning packaging suitable for packaging an object with a circular contour such as a spectacle lens, this package comprising:
  • a bottom panel;
  • two boxes each having an outer side panel and an inner side panel which has an opening for at least partial insertion of the object, each box being attached by a hinge to the bottom panel along a respective one of two opposite edges, each box being adapted to admit a slaughtered position in which the outer side panel extends in the extension of the bottom panel, and a raised position in which the outer side panel is erected relative to the bottom panel;
  • two flaps each attached by a hinge to the bottom panel along a respective two opposite edges, adjacent to the boxes, each flap being adapted to admit a slaughtered position in which it extends in the extension of the bottom panel, and a raised position in which the flap is erected relative to the bottom panel, against the longitudinal ends of the boxes;
  • means for holding the boxes and the flaps in the raised position; characterized in that, for each box, said outer side panel has a first end connected by a hinge to the bottom panel, a second end connected by a hinge to a first end of an intermediate panel, the latter also comprising a second end connected by a hinge at a first end of said inner side panel, the latter also having a second end connected by a hinge to the bottom panel, along the hinge between the first end of the outer side panel and the bottom panel ; and in that at least two wedge tongues are disposed in the opening being attached to the inner side panel exclusively by an end opposite to the bottom panel, said tongues being juxtaposed.

L'emballage selon l'invention permet ainsi de caler de manière optimale et de transporter des objets de différentes formes et épaisseurs. Il n'est pas nécessaire, pour un diamètre donné, d'avoir des références d'emballage spécifiques à chaque type d'objet circulaire grâce à l'agencement des languettes de calage et des caissons fournissant un moyen de maintien modulable.The packaging according to the invention thus optimally stalls and transports objects of different shapes and thicknesses. It is not necessary, for a given diameter, to have packaging references specific to each type of circular object by virtue of the arrangement of the locking tabs and boxes providing a modulable holding means.

Cet emballage peut, de plus, être fait d'une seule pièce ce qui rend sa fabrication et son utilisation en production plus aisées et moins onéreuses.This packaging can, moreover, be made in one piece which makes its production and use in production easier and less expensive.

De préférence, les modes de réalisation et caractéristiques supplémentaires exposés ci-après sont mis en oeuvre, en raison de leur qualités de simplicité et de commodité.Preferably, the embodiments and additional features set forth below are implemented because of their simplicity and convenience.

Selon un mode de réalisation, dans chaque ouverture pratiquée dans les panneaux latéraux internes, quatre languettes de calage sont disposées, chaque languette de calage étant indépendante des autres et rattachée au panneau de fond par l'une de ses extrémités.According to one embodiment, in each opening made in the inner side panels, four locking tabs are arranged, each locking tab being independent of the others and attached to the bottom panel by one of its ends.

Les languettes de calage peuvent comporter au moins une pré-pliure transversale sur leur longueur.The locking tongues may comprise at least one transverse pre-fold along their length.

Selon un autre mode de réalisation, chaque caisson est formé d'une seule pièce avec le panneau de fond par un pan rectangulaire relié par une première pré-pliure au bord du panneau de fond, ledit pan comportant une seconde pré-pliure délimitant le panneau latéral externe, une troisième pré-pliure délimitant le panneau intermédiaire, une quatrième pré-pliure délimitant le panneau latéral interne, ledit pan s'étendant au-delà de la quatrième pré-pliure par un rabat de fixation solidarisé au panneau de fond de sorte que la quatrième pré-pliure soit juxtaposée avec la première pré-pliure.According to another embodiment, each box is formed in one piece with the bottom panel by a rectangular panel connected by a first pre-fold to the edge of the bottom panel, said pan having a second pre-fold defining the panel external side, a third pre-fold delimiting the intermediate panel, a fourth pre-fold delimiting the internal side panel, said pan extending beyond the fourth pre-fold by a fastening flap secured to the bottom panel so that the fourth pre-fold is juxtaposed with the first pre-fold.

De plus, le panneau intermédiaire peut comporter une pré-pliure longitudinale, celle-ci pouvant être disposée sensiblement le long de la médiane longitudinale du panneau intermédiaire.In addition, the intermediate panel may comprise a longitudinal pre-fold, which may be arranged substantially along the longitudinal median of the intermediate panel.

Par ailleurs, la largeur du panneau latéral externe peut être sensiblement égale à la largeur du panneau latéral interne.Furthermore, the width of the outer side panel may be substantially equal to the width of the inner side panel.

Également dans un autre mode de réalisation, les moyens pour maintenir les caissons et les rabats en position relevée comportent des moyens associés aux rabats et aux caissons pour maintenir les caissons en position relevée lorsque les rabats sont en position relevée ainsi que des moyens pour maintenir les rabats en vis-à-vis, contre les caissons.Also in another embodiment, the means for holding the boxes and the flaps in the raised position include means associated with the flaps and boxes to maintain the boxes in the raised position when the flaps are in the raised position and means to maintain the flaps vis-à-vis, against the boxes.

Ces moyens pour maintenir les caissons et les rabats en position relevée peuvent comporter un panneau de fermeture articulé au bord libre d'un des rabats, ce panneau de fermeture pouvant comporter des moyens d'attache aux caissons et au rabat opposé, de manière à être apte à prendre une position de fermeture dans laquelle il est parallèle au panneau de fond et positionné contre les caissons et le bord libre du rabat opposé, lorsque ceux-ci sont en position relevée.These means for holding the boxes and the flaps in the raised position may comprise a closing panel hinged to the free edge of one of the flaps, this closure panel may comprise means of attachment to the boxes and the opposite flap, so as to be adapted to take a closed position in which it is parallel to the bottom panel and positioned against the boxes and the free edge of the opposite flap, when they are in the raised position.

Le panneau de fermeture peut comporter, au delà d'une pré-pliure et à partir de son extrémité opposée au rabat sur lequel il est articulé, un panneau de repli apte à se superposer au rabat opposé lorsque le panneau de fermeture est en position de fermeture.The closure panel may comprise, beyond a pre-fold and from its end opposite the flap on which it is hinged, a foldback panel adapted to be superimposed on the opposite flap when the closure panel is in the position of closing.

Les moyens d'attache évoqués peuvent comprendre des languettes d'attache saillantes des bords du panneau de fermeture, les caissons et le rabat opposé pouvant comporter des encoches aptes à coopérer avec ces languettes d'attache.The attachment means mentioned may comprise fastening tabs protruding from the edges of the closure panel, the boxes and the opposite flap may include notches adapted to cooperate with these fastening tabs.

Enfin, les rabats peuvent être rattachés chacun aux extrémités longitudinales adjacentes des caissons par deux goussets.Finally, the flaps may each be attached to the adjacent longitudinal ends of the boxes by two gussets.

Sous un deuxième aspect, l'invention vise un flan d'emballage en matériau en feuille, comportant :

  • un panneau de fond ;
  • deux panneaux latéraux externes reliés par une pré-pliure à deux bords opposés du panneau de fond;
  • deux rabats reliés chacun par une pré-pliure à l'un respectif de deux autres bords opposés du panneau de fond;
  • deux panneaux intermédiaires reliés par une pré-pliure à chacun des bords opposés au panneau de fond des deux panneaux latéraux externes;
  • deux panneaux latéraux internes reliés chacun par une pré-pliure à l'un respectif desdits panneaux intermédiaires, au niveau du bord de celui-ci opposé au panneau latéral externe, chacun de ces panneaux latéraux internes se prolongeant, dans la direction opposée au panneau intermédiaire, par un rabat de fixation, ces panneaux latéraux internes comportant en outre une découpe délimitant au moins deux languettes juxtaposées restant rattachées au reste du panneau par l'une de leurs extrémités ;
  • un panneau de fermeture de dimensions sensiblement égales à celles du panneau de fond et relié par une pré-pliure à un bord opposé au panneau de fond d'un des rabats.
In a second aspect, the invention provides a packaging blank made of sheet material, comprising:
  • a bottom panel;
  • two external side panels connected by a pre-bend at two opposite edges of the bottom panel;
  • two flaps each connected by a pre-bend to a respective one of two other opposite edges of the bottom panel;
  • two intermediate panels connected by a pre-fold to each of the opposite edges to the bottom panel of the two outer side panels;
  • two inner side panels each connected by a pre-bend to a respective one of said intermediate panels, at the edge thereof opposite to the outer side panel, each of these inner side panels extending in the opposite direction to the intermediate panel , by a fastening flap, these inner side panels further comprising a cutout defining at least two juxtaposed tabs remaining attached to the rest of the panel by one of their ends;
  • a closure panel of dimensions substantially equal to those of the bottom panel and connected by a pre-fold to an edge opposite to the bottom panel of one of the flaps.

La largeur du panneau latéral externe et la largeur du panneau latéral interne de ce flan d'emballage peuvent être sensiblement égales.The width of the outer side panel and the width of the inner side panel of this packaging blank may be substantially equal.

Selon un mode de réalisation, les panneaux latéraux externes et les rabats sont reliés deux à deux, au niveau de leurs extrémités adjacentes au panneau de fond, par un gousset.According to one embodiment, the outer side panels and the flaps are connected in pairs, at their ends adjacent to the bottom panel, by a gusset.

De même, les largeurs de chacun des rabats et de chacun des panneaux latéraux externes peuvent être sensiblement égales,Likewise, the widths of each of the flaps and of each of the external lateral panels may be substantially equal,

Sous un troisième aspect, l'invention vise un procédé d'emballage et de calage d'un objet à contour circulaire, ce procédé employant un emballage tel que décrit précédemment.In a third aspect, the invention provides a method of packaging and stalling an object with a circular contour, this method employing a package as described above.

Ce procédé prévoit de choisir un ensemble emballage - objet à emballer où le panneau de fond est un carré dont le côté est sensiblement égal au diamètre du verre.This method provides for choosing a package - object package to be packaged where the bottom panel is a square whose side is substantially equal to the diameter of the glass.

Other features and advantages of the invention will emerge in the light of the following description of a preferred embodiment given by way of non-limiting example, description made with reference to the appended drawings in which:
  • the figure 1 is a perspective view of a package according to the invention open, the spectacle lens wedged being visible inside;
  • the figure 2 is a perspective view of the whole of the figure 1 the package being closed;
  • the figure 3 is a top view of the packaging in the position of the figure 1 except that, for ease of understanding, the closing panel is an extension of the bottom panel;

  • the figure 5 is a view similar to the figure 4 , according to the VV cutting plane of the figure 3 ;
  • the figure 6 is a partial perspective view showing a glass of glasses in place and a box, the outer side panel of the box having been partially cut so as to see the positioning of the locking tabs;
  • the figure 7 is a top view similar to the figure 3 , the side boxes being in the folded position and the spectacle lens not being shown;
  • the figure 8 is a view following a materialized detail on the figure 7 by the inset VIII, showing precisely the wedge tongues;
  • the figure 9 is a top view of the flat blank intended to form the packaging of the figure 1 by the junction of the gray parts; and
  • the figure 10 is a view similar to the figure 7 , the boxes being flattened.

Sur les figures, les conventions de dessins suivantes ont été adoptées dans un but de clarté :

  • les pré-pliures simples sont représentées en traits fins mixtes (par exemple : la pré-pliure 44) ;
  • les encoches linéaires pratiquées dans le matériau de l'emballage sont représentées en trait continu fort (par exemple 55) ;
  • les pré-pliures formées de découpes pointillées sont représentées en pointillés forts (par exemple 36).
In the figures, the following drawing conventions have been adopted for the sake of clarity:
  • the simple pre-folds are represented in mixed fine lines (for example: the pre-fold 44);
  • the linear notches made in the packaging material are represented in solid continuous line (for example 55);
  • the pre-folds formed of dotted cutouts are represented in strong dotted lines (for example 36).

Néanmoins, les conventions précédentes ne s'appliquent pas aux vues en perspective (figures 1, 2, 6).Nevertheless, the preceding conventions do not apply to perspective views ( Figures 1, 2 , 6 ).

De plus, les pré-pliures prévues sur les languettes de calage ne sont représentées suivant cette convention que sur la figure 8 en raison de leur petite taille sur les autres dessins.In addition, the pre-folds provided on the wedge tongues are represented according to this convention only on the figure 8 because of their small size on the other drawings.

En référence aux figures 1, et 3, l'emballage 1 comporte un panneau de fond 2, deux caissons latéraux 3, deux rabats 4, 5 ainsi qu'un panneau de fermeture 6.With reference to figures 1 , and 3 , the package 1 comprises a bottom panel 2, two side boxes 3, two flaps 4, 5 and a closure panel 6.

Les caissons latéraux 3 sont disposés le long de deux bords 7 opposés du panneau de fond 2, ils sont identiques et s'étendent parallèlement l'un à l'autre en reposant de toute leur longueur sur le panneau de fond 2.The side boxes 3 are arranged along two opposite edges 7 of the bottom panel 2, they are identical and extend parallel to each other by resting their entire length on the bottom panel 2.

Ces caissons 3 présentent par ailleurs une section triangulaire 8 (voir figure 1) qui vient renforcer la rigidité de la structure, laquelle est constituée à partir d'un matériau en feuille tel que du carton.These boxes 3 also have a triangular section 8 (see figure 1 ) which reinforces the rigidity of the structure, which is formed from a sheet material such as cardboard.

Cette structure 8 est obtenue pour chaque caisson 3 par la liaison, le long d'une pré-pliure 9, d'un panneau latéral externe 10 avec un panneau intermédiaire 11, celui-ci étant lui-même relié, le long d'une pré-pliure 12, à un panneau latéral interne 13. Ces panneaux 10, 11, 13 sont tous trois de forme rectangulaire, chacun ayant une longueur égale de préférence à celle du bord 7 du panneau de fond 2 auquel le caisson 3 correspondant se rattache.This structure 8 is obtained for each box 3 by the connection, along a pre-bend 9, of an outer side panel 10 with an intermediate panel 11, the latter being itself connected, along a pre-fold 12, to an inner side panel 13. These panels 10, 11, 13 are all rectangular in shape, each having a length preferably equal to that of the edge 7 of the bottom panel 2 to which the corresponding box 3 is attached. .

Le rattachement de chaque caisson 3 au panneau de fond 2 est effectué selon une pré-pliure 14 commune au bord 7 du panneau de fond 2 et à une extrémité linéaire du caisson 3 correspondant à l'un des sommets du triangle décrit par la section 8 du caisson 3.The attachment of each box 3 to the bottom panel 2 is made according to a pre-fold 14 common to the edge 7 of the bottom panel 2 and to a linear end of the box 3 corresponding to one of the vertices of the triangle described by section 8 of the box 3.

Chaque caisson 3, formé par conséquent par un profilé triangulaire 8, est ainsi mobile le long de la pré-pliure 14 entre une position abattue dans laquelle le panneau latéral externe 10 est disposé dans le même plan que le panneau de fond 2 (figure 7) et une position relevée dans laquelle le panneau latéral externe 10 est disposé perpendiculairement au panneau de fond 2 (figures 1, 3, 4 et 5).Each casing 3, consequently formed by a triangular profile 8, is thus movable along the pre-bend 14 between a sloped position in which the external lateral panel 10 is arranged in the same plane as the bottom panel 2 ( figure 7 ) and a raised position in which the outer side panel 10 is disposed perpendicularly to the bottom panel 2 ( figures 1 , 3, 4 and 5 ).

Chaque caisson 3 comporte par ailleurs une ouverture 15 pratiquée dans son panneau latéral interne 13. Cette ouverture 15 a une forme rectangulaire centrée sur la longueur du panneau latéral interne 13, l'un 16 des bords de plus grande longueur la délimitant débouchant à ras du panneau de fond 2 et l'autre 17 des bords de plus grande longueur la délimitant débouchant à proximité de la jonction 12 du panneau latéral interne 13 et du panneau intermédiaire 11. Cette ouverture 15 est destinée à l'engagement au moins partiel d'un verre de lunettes 18 lorsque les caissons 3 sont en position relevée, tel qu'on peut le voir à la figure 1.Each casing 3 also has an opening 15 made in its internal lateral panel 13. This opening 15 has a rectangular shape centered on the length of the internal lateral panel 13, one 16 of the edges of greater length the delimiting opening flush with the bottom panel 2 and the other 17 edges of greater length delimiting opening in the vicinity of the junction 12 of the inner side panel 13 and the intermediate panel 11. This opening 15 is intended for the at least partial engagement of a spectacle lens 18 when the boxes 3 are in the raised position, as can be seen in FIG. figure 1 .

La longueur de l'ouverture 15 a été déterminée en fonction du diamètre maximal du verre 18 et de la forme du caisson 3, de façon à être, de préférence, assez importante pour garantir que le verre 18 vienne tout au plus buter contre les bords 19, délimitant latéralement l'ouverture, lorsqu'il est en place dans l'emballage 1 et que les caissons 3 sont en position relevée.The length of the opening 15 was determined as a function of the maximum diameter of the glass 18 and the shape of the box 3, so as to be, preferably, large enough to ensure that the glass 18 comes at the most against the edges 19, laterally delimiting the opening, when it is in place in the package 1 and the boxes 3 are in the raised position.

Chaque caisson 3 comporte de plus quatre languettes de calage 20, 21 saillantes du bord 17 délimitant l'ouverture 15 opposé au panneau de fond 2. Elles sont articulées suivant une pré-pliure 22 au ras dudit bord 17.Each box 3 further comprises four wedging tongues 20, 21 protruding from the edge 17 delimiting the opening 15 opposite the bottom panel 2. They are articulated in a pre-fold 22 flush with said edge 17.

Ces languettes 20, 21 sont de forme rectangulaire, leur longueur s'étendant sur toute la largeur de l'ouverture 15.These tongues 20, 21 are of rectangular shape, their length extending over the entire width of the opening 15.

Pour chaque caisson 3, il convient de différencier les deux languettes centrales 20, situées de part et d'autre d'un axe médian, et les deux languettes latérales 21, encadrant les précédentes et longeant les bords 19 délimitant latéralement l'ouverture 15.For each box 3, it is necessary to differentiate the two central tongues 20, located on either side of a central axis, and the two lateral tongues 21, flanking the preceding and along the edges 19 laterally delimiting the opening 15.

Les quatre languettes de calage 20, 21 de chaque caisson 3 sont quoi qu'il en soit juxtaposées les unes aux autres et sont aptes à occuper toute la section de l'ouverture 15 lorsqu'elles se trouvent disposées dans le plan du panneau latéral interne 13.The four locking tabs 20, 21 of each box 3 are in any case juxtaposed with each other and are able to occupy the entire section of the opening 15 when they are arranged in the plane of the internal side panel 13.

Les languettes centrales 20, aussi bien que les languettes latérales 21, sont libres de toute attache sur leurs côtés de plus grande longueur 23 ainsi que sur leur côté 24 coïncidant avec le bord 16 délimitant l'ouverture 15 venant à ras du panneau de fond 2, seul leur rattachement 22 au bord 17 délimitant l'ouverture 15 opposé au panneau de fond 2 leur permet d'être solidaires du panneau latéral interne 13.The central tongues 20, as well as the lateral tongues 21, are free from any fastening on their longer sides 23 as well as on their side 24 coinciding with the edge 16 defining the opening 15 flush with the bottom panel 2 , only their attachment 22 to the edge 17 delimiting the opening 15 opposite the bottom panel 2 allows them to be integral with the inner side panel 13.

Outre les pré-pliures 22 les rattachant au panneau de fond 2, les languettes 20, 21 comprennent chacune, sur leur longueur, trois autres pré-pliures transversales 25 délimitant chaque languette 20 ; 21 en quatre portions environ égales.In addition to the pre-folds 22 attaching them to the bottom panel 2, the tongues 20, 21 each comprise, along their length, three other pre-folds transverse 25 delimiting each tongue 20; 21 in four approximately equal portions.

Globalement, cet agencement résulte pour chaque caisson 3 en quatre languettes 20, 21 librement mobiles autour d'un axe 22 confondu avec le bord 17 délimitant l'ouverture 15 opposé au panneau de fond 2, ce mouvement permettant à l'extrémité libre 26 de chaque languette 20 ; 21 de se positionner d'un côté, ou de l'autre, du plan du panneau latéral interne 13.Overall, this arrangement results for each box 3 in four tongues 20, 21 freely movable about an axis 22 coincides with the edge 17 defining the opening 15 opposite the bottom panel 2, this movement allowing the free end 26 of each tab 20; 21 to be positioned on one side or the other of the plane of the inner side panel 13.

On notera que ce mouvement induit une déformation élastique de la languette de calage 20 ; 21 au niveau de la pré-pliure 22 la rattachant au panneau latéral interne 13, en fonction des propriétés élastiques du matériau en feuille employé pour confectionner le panneau latéral interne 13 ou la languette 20 ; 21 (il s'agit, dans notre exemple, de carton).It will be noted that this movement induces an elastic deformation of the locking tongue 20; 21 at the pre-fold 22 attaching it to the inner side panel 13, depending on the elastic properties of the sheet material used to make the inner side panel 13 or the tongue 20; 21 (this is, in our example, cardboard).

De même, les languettes 20, 21 sont aptes à une déformation élastique suivant chacune des pré-pliures 25 disposées sur leur longueur.Similarly, the tongues 20, 21 are capable of elastic deformation following each of the pre-bends 25 arranged along their length.

En ce qui concerne les rabats 4, 5, ceux-ci sont disposés de part et d'autre de deux bords 27, 28 opposés du panneau de fond 2, chacun le long d'une ligne de pré-pliage 29 ; 30, et sont par conséquent adjacents aux caissons 3, ces derniers occupant les deux autres bords 7 opposés du panneau de fond 2.With regard to the flaps 4, 5, these are arranged on either side of two opposite edges 27, 28 of the bottom panel 2, each along a pre-folding line 29; 30, and are therefore adjacent to the caissons 3, the latter occupying the other two opposite edges 7 of the bottom panel 2.

De manière visible à la figure 9, le panneau de fond 2 est ainsi prolongé en étoile, c'est-à-dire à partir de chacun de ses bords 7, 27, 28, par quatre panneaux 4, 5, 10, dans la mesure où les rabats 4, 5 sont de forme rectangulaire et sensiblement identiques aux panneaux latéraux externes 10.Visibly at the figure 9 , the bottom panel 2 is thus extended star, that is to say from each of its edges 7, 27, 28, by four panels 4, 5, 10, to the extent that the flaps 4, 5 are of rectangular shape and substantially identical to the external side panels 10.

A l'instar des caissons 3, ou plus précisément des panneaux latéraux externes 10, les rabats 4, 5 sont mobiles entre une position abattue dans laquelle le rabat 4 ; 5 s'étend dans le même plan que le panneau de fond 2 (figures 3, 7 et 10) et une position relevée dans laquelle le rabat 4 ; 5 se dresse sensiblement perpendiculairement au panneau de fond 2 (figure 2).Like caissons 3, or more precisely outer side panels 10, the flaps 4, 5 are movable between a slaughtered position in which the flap 4; 5 extends in the same plane as the bottom panel 2 ( figures 3 , 7 and 10 ) and a raised position in which the flap 4; 5 stands substantially perpendicular to the bottom panel 2 ( figure 2 ).

Il en résulte que, lorsque les rabats 4, 5 et les caissons 3 sont en position relevée, les rabats 4, 5 viennent se positionner contre l'extrémité des profils triangulaires 8 formant les caissons 3, ces rabats 4, 5 et les panneaux latéraux externes 10 étant ainsi aptes à former les côtés d'une boîte dont le panneau de fond 2 forme le fond (voir figure 2).As a result, when the flaps 4, 5 and the boxes 3 are in the raised position, the flaps 4, 5 are positioned against the end of the triangular profiles 8 forming the boxes 3, these flaps 4, 5 and the side panels 10 being thus able to form the sides of a box whose bottom panel 2 forms the bottom (see figure 2 ).

En position relevée, les côtés 31 de plus petite longueur des rabats 4, 5 et des panneaux latéraux externes 10 coïncident deux à deux de manière à former les arêtes de la boîte.In the raised position, the shorter sides 31 of the flaps 4, 5 and the outer side panels 10 coincide in pairs so as to form the edges of the box.

Pour faciliter cette mise en coïncidence, il est prévu quatre goussets 32 réalisant la jonction de chaque bord 31 des rabats avec le bord adjacent 33 du panneau latéral externe 10. Sur la figure 9, représentant le flan 34 de l'emballage 1, les panneaux latéraux externes 10 et les rabats 4, 5 sont disposés dans le plan du panneau de fond 2. Chaque gousset 32 apparaît sur cette figure comme un volet se raccordant aux rabats 4, 5 et au panneau latéral externe 10 qu'il relie par deux pré-pliures 35, l'une dans le prolongement de la pré-pliure 29 ; 30 reliant le rabat 4 ; 5 au panneau de fond 2 et l'autre dans le prolongement de la pré-pliure 14 reliant le panneau latéral externe 10 au panneau de fond 2.To facilitate this coincidence, there are four gussets 32 forming the junction of each edge 31 of the flaps with the adjacent edge 33 of the outer side panel 10. On the figure 9 , representing the blank 34 of the package 1, the outer side panels 10 and the flaps 4, 5 are arranged in the plane of the bottom panel 2. Each gusset 32 appears in this figure as a flap connecting to the flaps 4, 5 and the outer side panel 10 that connects by two pre-bends 35, one in the extension of the pre-fold 29; 30 connecting the flap 4; 5 to the bottom panel 2 and the other in the extension of the pre-fold 14 connecting the outer side panel 10 to the bottom panel 2.

Le gousset 32 est enfin complété par une pré-pliure centrale 36 partant de l'angle 37 correspondant du panneau de fond 2 et s'étendant à 45° vers l'extrémité du gousset 32. Lors de la mise en position relevée des caissons 3 et des rabats 4, 5, les goussets 32 se replient vers l'intérieur (voir figure 1) et garantissent que lorsque les rabats 4, 5 sont maintenus contre les caissons 3, ces derniers sont immobilisés en position relevée.The gusset 32 is finally completed by a central pre-bend 36 starting from the corresponding angle 37 of the bottom panel 2 and extending at 45 ° towards the end of the gusset 32. When the caissons 3 are placed in the raised position and flaps 4, 5, the gussets 32 fold inwards (see figure 1 ) and ensure that when the flaps 4, 5 are held against the caissons 3, the latter are immobilized in the raised position.

L'emballage 1 pour verre de lunettes 18 comporte en outre un panneau de fermeture 6, de dimensions identiques à celle du panneau de fond 2, rattaché par une pré-pliure 38 à l'extrémité libre d'un 5 des rabats, ce panneau de fermeture 6 étant ainsi apte à former un couvercle, parallèlement au panneau de fond 2, pour la boîte formée par les caissons 3 et les rabats 4, 5 en position relevée.The packaging 1 for spectacle lens 18 further comprises a closure panel 6, of identical dimensions to that of the bottom panel 2, attached by a pre-fold 38 to the free end of one of the flaps, this panel closure 6 being thus able to form a cover, parallel to the bottom panel 2, for the box formed by the boxes 3 and the flaps 4, 5 in the raised position.

Des moyens pour maintenir le panneau de fermeture 6 dans sa fonction de couvercle ont été prévus. Il s'agit ici de deux languettes d'attache 39 saillantes du panneau de fermeture 6, plus précisément de ses deux bords 40 opposés qui sont perpendiculaires à la pré-pliure 38 le reliant au rabat 5. Ces languettes d'attache 39, délimitées chacune par une pré-pliure 41 dans l'alignement du bord 40 du panneau de fermeture 6, sont aptes à coopérer avec deux encoches 42 pratiquées chacune sur l'un des panneaux intermédiaires 11.Means for holding the closure panel 6 in its lid function have been provided. These are two fastening 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 fastening tabs 39, delimited each by a pre-fold 41 in the alignment of the edge 40 of the closure panel 6, are adapted to cooperate with two notches 42 each formed on one of the intermediate panels 11.

Il est également prévu un panneau de repli 43, saillant au-delà d'une pré-pliure 44 du bord 45 du panneau de fermeture 6 opposé au rabat 5 et sur une distance environ égale à la largeur des rabats 5, 6.There is also provided a folding panel 43 protruding beyond a pre-bend 44 of the edge 45 of the closure panel 6 opposite the flap 5 and a distance approximately equal to the width of the flaps 5, 6.

Ce panneau de repli 43 est lui-même prolongé, sur son bord opposé au panneau de fermeture 6, par une troisième languette d'attache 46, le long d'une pré-pliure 47, cette languette d'attache 46 étant apte à coopérer avec une encoche 48 pratiquée dans le rabat opposé 4, au niveau de sa jonction 29 avec le panneau de fond 2.This folding panel 43 is itself extended, on its edge opposite the closure panel 6, by a third attachment tab 46, along a pre-fold 47, this attachment tab 46 being able to cooperate with a notch 48 made in the opposite flap 4, at its junction 29 with the bottom panel 2.

L'emballage 1 peut ainsi être maintenu dans la position de la figure 2, les caissons 3 et les rabats 4, 5 étant en position relevée, ie panneau de fermeture 6 les recouvrant et le panneau de repli 43 venant se plaquer contre le rabat 4 correspondant. Les trois languettes 39, 46 insérées dans leurs encoches 42, 48 correspondantes permettent de maintenir la cohésion et la rigidité de l'emballage 1 fermé.The package 1 can thus be maintained in the position of the figure 2 , the boxes 3 and the flaps 4, 5 being in the raised position, the closure panel 6 covering them and the foldback panel 43 coming to press against the corresponding flap 4. The three tabs 39, 46 inserted into their notches 42, 48 correspond to maintain the cohesion and rigidity of the package 1 closed.

Ces éléments coopèrent pour protéger et caler le verre 18 dans toutes les directions de l'espace. Il peut être constaté sur les figures 1 et 2 que le verre 18 situé à l'intérieur de l'emballage 1 est calé suivant un de ses axes diamétraux par les deux caissons latéraux 3, et suivant un deuxième de ses axes diamétraux, perpendiculaire au premier, par les deux rabats 4, 5, le panneau de fond 2 et le panneau de fermeture 6 prenant place de part et d'autre du verre 18, perpendiculairement aux rabats 4, 5 et caissons 3.These elements cooperate to protect and wedge the glass 18 in all directions of space. It can be seen on Figures 1 and 2 that the glass 18 located inside the package 1 is wedged along one of its diametral axes by the two lateral caissons 3, and along a second of its diametrical axes, perpendicular to the first, by the two flaps 4, 5, the bottom panel 2 and the closure panel 6 taking place on either side of the glass 18, perpendicularly to the flaps 4, 5 and boxes 3.

L'emballage 1 est ainsi prêt à être transporté, gerbé ou tout simplement manipulé, sans dommage pour le verre de lunettes 18.The package 1 is thus ready to be transported, stacked or simply handled, without damage to the spectacle lens 18.

Sur la figure 9 est représenté le flan 34 adapté à former l'emballage 1 décrit.On the figure 9 is shown the blank 34 adapted to form the package 1 described.

Il comporte un panneau central 49 carré dont chaque angle a subi deux entailles symétriques. Dans ce panneau central 49 sont délimités un panneau de fond 2, deux panneaux latéraux externes 10, deux rabats 4, 5 et quatre goussets 32.It comprises a central 49 square panel whose each angle has undergone two symmetrical notches. In this central panel 49 are delimited a bottom panel 2, two external side panels 10, two flaps 4, 5 and four gussets 32.

Les pré-pliures suivantes, pratiquées sur ce panneau central 49, sont destinées à délimiter les parties évoquées :

  • deux pré-pliures 14 reliant le panneau de fond 2 aux panneaux latéraux externes 10 ;
  • deux pré-pliures 29, 30 reliant le panneau de fond 2 aux rabats 4, 5 ;
  • quatre pré-pliures 35 reliant les panneaux latéraux externes 10 aux goussets 32 ;
  • quatre pré-pliures 35 reliant les rabats 4, 5 aux goussets 32.
The following pre-folds, made on this central panel 49, are intended to delimit the parts evoked:
  • two pre-folds 14 connecting the bottom panel 2 to the outer side panels 10;
  • two pre-folds 29, 30 connecting the bottom panel 2 to the flaps 4, 5;
  • four pre-folds 35 connecting the outer side panels 10 to the gussets 32;
  • four pre-folds 35 connecting the flaps 4, 5 to the gussets 32.

Au niveau de chaque gousset 32, une pré-pliure centrale 36 est ménagée par une ligne de perforation en pointillé.At each gusset 32, a central pre-bend 36 is formed by a dotted perforation line.

Le flan 34 comporte également, s'étendant à partir du bord 50 opposé au panneau de fond 2 de chaque panneau latéral externe 10, un panneau de caisson 51 rattaché par une pré-pliure 9 audit bord 50. Chacun de ces panneaux de caissons 51 comporte une première 12 et deuxième 52 pré-pliure simple délimitant successivement un panneau intermédiaire 11, un panneau latéral interne 13 et un rabat de fixation 53.The blank 34 also includes, extending from the edge 50 opposite the bottom panel 2 of each outer side panel 10, a box panel 51 attached by a pre-bend 9 to said edge 50. Each of these box panels 51 comprises a first 12 and second 52 single pre-fold delimiting successively an intermediate panel 11, an inner side panel 13 and a fastening flap 53.

Sur le panneau intermédiaire 11 est également ménagée une pré-pliure 54, traversant longitudinalement ce panneau 11 le long d'une ligne médiane, cette pré-pliure 54 recevant trois encoches 55 réparties sur sa longueur de manière à favoriser le pliage.On the intermediate panel 11 is also formed a pre-bending 54, passing longitudinally along this panel 11 along a center line, this pre-bend 54 receiving three notches 55 distributed over its length so as to promote folding.

Le panneau latéral interne 13 reçoit, quant à lui, une découpe 15 correspondant à l'ouverture décrite précédemment consistant en la découpe de trois côtés d'un rectangle dont l'un coïncide avec ladite deuxième pré-pliure 52, ainsi que trois découpes à l'intérieur dudit rectangle et perpendiculaires à cette deuxième pré-pliure 52, délimitant quatre languettes de calage 20, 21 rattachées par l'une de leurs extrémités au panneau latéral interne 13.The internal lateral panel 13 receives, meanwhile, a cutout 15 corresponding to the opening described above consisting of the cutting of three sides of a rectangle, one of which coincides with said second pre-bend 52, as well as three cutouts. inside said rectangle and perpendicular to this second pre-bend 52, delimiting four wedging tongues 20, 21 attached by one of their ends to the inner side panel 13.

Une pré-pliure simple 22 est d'autre part formée sur chaque languette de calage 20, 21 au niveau de son rattachement au panneau latéral interne 13, ainsi que trois autres pré-pliures transversales 25 réparties sur la longueur de la languette 20 ; 21.A simple pre-fold 22 is furthermore formed on each wedging tongue 20, 21 at its attachment to the inner side panel 13, as well as three other transverse pre-folds 25 distributed along the length of the tongue 20; 21.

Le flan 34 comporte enfin un panneau de couvercle 56 rattaché par une pré-pliure 38 au bord libre d'un des rabats 5, ce panneau de couvercle 56 comportant une pré-pliure 44 délimitant successivement, à partir dudit bord libre, un panneau de fermeture 6 et un panneau de repli 43, le panneau de couvercle 56 comportant une languette d'attache 39, 46 sur chacun de ses bords libres : deux languettes d'attache 39 en vis-à-vis destinées à coopérer avec les deux encoches 42 pratiquées au niveau de la jonction 9 des panneaux latéraux externes 10 et des panneaux intermédiaires 11, ainsi qu'une troisième languette d'attache 46 destinée à coopérer avec une encoche 48 pratiquée le long de la pré-pliure 29 de jonction entre le panneau de fond 2 et le rabat opposé 4.The blank 34 finally comprises a cover panel 56 attached by a pre-fold 38 to the free edge of one of the flaps 5, this cover panel 56 having a pre-fold 44 delimiting successively, from said free edge, a panel of closure 6 and a folding panel 43, the cover panel 56 having an attachment tongue 39, 46 on each of its free edges: two tongues of attachment 39 vis-à-vis intended to cooperate with the two notches 42 practiced at the junction 9 of the side panels 10 and intermediate panels 11, and a third attachment tab 46 intended to cooperate with a notch 48 made along the pre-fold 29 of junction between the bottom panel 2 and the opposite flap 4.

La formation de l'emballage 1 pour verre de lunettes 18 à partir du flan 34 décrit se fait simplement en collant chaque rabat de fixation 53 sur le bord 7 correspondant du panneau de fond 2 (zone grisée sur la figure 9) de manière à juxtaposer la pré-pliure 52 joignant le panneau latéral interne 13 aux rabats de fixation 53 et la pré-pliure 14 joignant le panneau latéral externe 10 au panneau de fond 2. Le panneau latéral externe 10, le panneau intermédiaire 11 et le panneau latéral interne 13 forment ainsi un profilé triangulaire 8.The formation of the packaging 1 for spectacle lens 18 from the blank 34 described is simply done by gluing each fastening flap 53 on the corresponding edge 7 of the bottom panel 2 (shaded area on the figure 9 ) so as to juxtapose the pre-fold 52 joining the inner side panel 13 to the fastening flaps 53 and the pre-fold 14 joining the outer side panel 10 to the bottom panel 2. The outer side panel 10, the intermediate panel 11 and the inner side panel 13 thus form a triangular profile 8.

Tandis que la figure 9 représente le flan 34 avant collage, la figure 7 représente le flan 34 une fois cette opération de collage effectué, les caissons 3 étant alors formés (ils sont vus de dessus sur la figure 9) et une simple opération de pliage pour la mise en position relevée des caissons 3 permet d'obtenir un emballage 1 prêt à l'emploi, tel que visible sur la figure 1.While the figure 9 represents the blank 34 before gluing, the figure 7 represents the blank 34 after this bonding operation performed, the boxes 3 being then formed (they are seen from above on the figure 9 ) and a simple folding operation for the raised position of the boxes 3 provides a package 1 ready to use, as visible on the figure 1 .

En pratique, chez le fabricant de l'emballage 1, le contour du flan 34 est tout d'abord découpé, les différentes encoches et découpes étant également effectuées, les pré-pliures sont réalisées et le collage des rabats de fixation 53 sur le bord 7 correspondant est effectué, en maintenant les caissons 3 repliés le long de leur pré-pliure 54, de sorte à obtenir le flan plat de la figure 10. L'emballage 1 peut ainsi être avantageusement livré selon des conditionnements dans lesquels les flans 34 encollés et aplatis sont superposés.In practice, at the manufacturer of the packaging 1, the contour of the blank 34 is first cut, the various notches and cutouts being also made, the pre-folds are made and the bonding of the fastening flaps 53 on the edge 7 is made, keeping the boxes 3 folded along their pre-fold 54, so as to obtain the flat blank of the figure 10 . Packaging 1 can thus advantageously be delivered according to packages in which the glued and flattened blanks 34 are superimposed.

Lors de la réception d'une de ces formes plates par l'utilisateur, celui-ci commence par déplier le panneau intermédiaire 11 et éloigner les panneau latéraux interne 13 et externe 10 l'un de l'autre, de façon à constituer le profil triangulaire 8 des caissons 3.When one of these flat shapes is received by the user, the latter unfolds the intermediate panel 11 and moves the inner and outer lateral panels 13 away from each other so as to constitute the profile. triangular 8 of the caissons 3.

L'emballage 1, alors tel que représenté à la figure 7, est apte pour un procédé d'emballage dans lequel le verre 18 est déposé sur le panneau de fond 2 puis les caissons 3 sont relevés (voir figures 1 et 3), les rabats 4, 5 sont repliés et le panneau de fermeture 6 mis en place pour aboutir à l'emballage fermé de la figure 2.Packing 1, as shown in FIG. figure 7 , is suitable for a packaging process in which the glass 18 is deposited on the bottom panel 2 and the boxes 3 are raised (see figures 1 and 3 ), the flaps 4, 5 are folded and the closure panel 6 put in place to lead to the closed packaging of the figure 2 .

Pour le calage optimum du verre de lunette 18, il a été prévu un emballage 1 avec un panneau de fond 2 carré de côté environ égal au diamètre du verre 18. Ce dernier s'insère ainsi dans les ouvertures 15 (figure 1), en repoussant les languettes de calage 20, 21 vers l'intérieur des caissons 3 (figures 4, 5 et 6).For the optimum setting of the spectacle lens 18, it was provided a package 1 with a bottom panel 2 square side approximately equal to the diameter 18. The latter thus fits into the openings 15 ( figure 1 ), by pushing the wedging tongues 20, 21 towards the inside of the caissons 3 ( Figures 4, 5 and 6 ).

La figure 6 est une représentation schématique sur laquelle le panneau latéral externe 10 d'un des caissons 3 est vu en transparence de manière à rendre visible le comportement des languettes de calage 20, 21 lors de l'insertion du verre 18 dans les ouvertures 15. La courbure du contour du verre 18 a pour conséquence de repousser les deux languettes centrales 20 plus loin vers l'intérieur du caisson 3 que les deux languettes latérales 21, ceci étant rendu possible par le fait que ces languettes de calage 20, 21 sont dépourvues d'attache au niveau du bord 16 de l'ouverture 15 à ras du panneau de fond 2.The figure 6 is a schematic representation on which the outer side panel 10 of one of the boxes 3 is viewed 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 The result of the glass contour 18 is to push the two central tongues 20 further towards the inside of the box 3 than the two lateral tongues 21, this being made possible by the fact that these wedging tongues 20, 21 are devoid of attachment at the edge 16 of the opening 15 flush with the bottom panel 2.

Les figures 4 et 5 montrent la position des languettes 20, 21 par rapport au verre 18 dans une vue suivant l'axe longitudinal des caissons 3. Il apparaît que les languettes de calage centrales 20 des caissons 3 viennent caler le verre 18 suivant un de ses diamètres, en s'adaptant à la circonférence et au profil du contour du verre 18. Les languettes de calage latérales 21, quant à elles, viennent également se positionner en s'adaptant à la courbure du verre 18 et exercent un calage par la pression opposée de chaque paire de languettes 20, 21 correspondantes en vis-à-vis sur chaque caisson 3. De plus, les languettes latérales 21 exercent également une retenue du verre 18 en cas de translation dans la direction longitudinale des caissons 3 puisque leurs bords latéraux viennent buter latéralement contre le contour du verre 18, à l'endroit où celui-ci s'enfonce plus profondément vers les languettes centrales 20.The Figures 4 and 5 show the position of the tabs 20, 21 with respect to the glass 18 in a view along the longitudinal axis of the boxes 3. It appears that the central locking tongues 20 of the boxes 3 stall the glass 18 according to one of its diameters, in s The lateral locking tongues 21, for their part, also position themselves by adapting to the curvature of the glass 18 and exert wedging by the opposite pressure of each pair. corresponding tabs 20, 21 facing each box 3. In addition, the lateral tabs 21 also exert a retention of the glass 18 in the case of translation in the longitudinal direction of the boxes 3 since their lateral edges abut laterally against the outline of the glass 18, at the place where the latter sinks deeper towards the central tongues 20.

Le calage du verre 18 est donc assuré par la pression conjointe de chaque couple de languettes 20, 21 opposées de part et d'autre de son diamètre, qu'elles soient centrales ou latérales, ainsi que par la pression des quatre languettes latérales 21 formant une cage de quatre points, adaptable au contour du verre 18 et l'empêchant de glisser latéralement.The wedging of the glass 18 is therefore ensured by the joint pressure of each pair of tabs 20, 21 opposite on either side of its diameter, whether central or lateral, as well as by the pressure of the four lateral tabs 21 forming a cage of four points, adaptable to the outline of the glass 18 and preventing it from slipping laterally.

En dehors du positionnement des languettes 20, 21 évoqué plus haut, la fonction de mise en pression du verre 18 par les couples de languettes 20, 21 opposées sur chaque caisson 3 est assurée conjointement par des propriétés élastiques du matériau des languettes 20, 21 ainsi que par la configuration des caissons 3 en profil triangulaire 8 permettant à l'extrémité libre 26 d'une languette, lorsqu'elle est sollicitée vers l'intérieur du caisson 3, de remonter le long de la paroi interne du panneau latéral externe 10 et éventuellement de s'arc-bouter contre celui-ci (voir figures 4 et 5), les pré-pliures 25 réparties le long de la languette 20 ; 21 favorisant ce comportement.Apart from the positioning of the tongues 20, 21 mentioned above, the function of pressurizing the glass 18 by the pairs of tabs 20, 21 opposite each box 3 is provided jointly by elastic properties of the tongue material 20, 21 and that by the configuration of the caissons 3 triangular profile 8 allowing the free end 26 of a tongue, when it is urged towards the inside of the box 3, to go up along the inner wall of the outer side panel 10 and possibly to be bent against it (see Figures 4 and 5 ), the pre-bends 25 distributed along the tongue 20; 21 favoring this behavior.

On observera que l'emballage décrit ici peut également être employé pour emballer et caler un objet à contour circulaire autre qu'un verre de lunettes non détouré, par exemple un autre type de lentille optique.It will be appreciated that the package described herein may also be used to package and stall a circular-contoured object other than a non-cut-off spectacle lens, for example another type of optical lens.
