Abstract

The pack, made from a single cut and folded panel designed to hold an article with a circular edge and comprising a base (2), sides (3) and a lid (6), has the two sides made from flaps (10) that are folded to form two triangular-section prisms with transverse slits on their inner surfaces (13) to create a series of flexible strips that accommodate the edges of the article. 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

Emballage de protection et de calage pour objets à contour circulaire Protective and cushioning packaging for objects with a circular outline
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 wedging packaging suitable for packaging objects with a circular outline, and more specifically to an object of dimension 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" lens is a spectacle lens of which only the convex face is finished (machined) in mass 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 takes care of 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 wedge the glass well to protect this finished face by avoiding any contact with it, in particular in the case of a glass made of organic material which 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. Ce verre est expédié par le fabricant à l'opticien qui le débordeIn the case of a finished glass, on the other hand, the two sides, concave and convex, are finished in series production. This glass is sent by the manufacturer to the optician who overflows it
(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).(detours) as a function of the shape of the frame selected by the wearer and of morphological parameters specific to that wearer (pupillary distance, position of the pupils relative to the circles of the frame).
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 antisalissures). Des emballages destinés à assurer un tel conditionnement sont connus de l'art antérieur.Here too, it is important to protect the faces of the glass, insofar as they are finished (that is to say machined and most often provided with treatment layers, for example, abrasion-resistant, anti-reflective or antifouling). 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 deformable, une découpe étant pratiquée dans chaque rebord en caisson, pour l'insertion au moins partielle du verre de lunettes.French patent application No. FR-2 703 654 describes a packaging-drawer for spectacle lenses consisting of an external envelope and a receptacle, the latter comprising a bottom panel, and two box edges articulated in a deformable parallelogram. , a cut being made in each rim in a box, for 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 drawer packaging receives the spectacle lens on its bottom panel and in the abovementioned cutouts, then is inserted into the external envelope, the whole forming a box capable of being transported.
Ces emballages donnent satisfaction quant à la réalisation de la fonction pour laquelle ils sont prévus.These packages are satisfactory as regards the performance of the function for which they are intended.
L'invention vise néanmoins à les améliorer, notamment en ce qui concerne le calage du verre.The invention nevertheless aims to improve them, in particular 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 une languette de calage est disposée dans l'ouverture en étant rattachée au panneau latéral interne exclusivement par une extrémité opposée au panneau de fond.To this end and according to a first object, the invention relates to a protective and wedging packaging suitable for packaging an object with a circular outline such as a spectacle lens, this packaging comprising: a bottom panel; - two boxes each comprising an external side panel and an internal side panel which has an opening for at least partial insertion of the object, each box being attached by an articulation to the bottom panel along a respective of two opposite edges, each box being adapted to admit a depressed position in which the external side panel extends in the extension of the bottom panel, and a raised position in which the external side panel is raised relative to the bottom panel; two flaps each attached by an articulation to the bottom panel along a respective of two opposite edges, adjacent to the boxes, each flap being adapted to admit a depressed position in which it extends in the extension of the bottom panel, and a raised position in which the flap is raised 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 external side panel has a first end connected by a joint to the bottom panel, a second end connected by a joint to a first end of an intermediate panel, the latter also comprising a second end connected by a joint to a first end of said internal side panel, the latter also comprising a second end connected by a joint to the bottom panel, along the joint between the first end of the external side panel and the bottom panel ; and in that at least one wedging tab is disposed in the opening, being attached to the internal side panel exclusively by an end opposite to the bottom panel.
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 makes it possible to optimally stall and transport objects of different shapes and thicknesses. It is not necessary, for a given diameter, to have specific packaging references for each type of circular object thanks to the arrangement of the wedging tongues and of the boxes providing a modular 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. De préférence, les modes de réalisation et caractéristiques supplémentaires exposés ci-après sont mis en œuvre, en raison de leur qualités de simplicité et de commodité.This packaging can, moreover, be made in one piece which makes its manufacture and its use in production easier and less expensive. Preferably, the embodiments and additional characteristics set out below are implemented, because of their qualities of 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 internal side panels, four wedging tabs are arranged, each wedging 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 wedging tabs may have 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 panel comprising a second pre-fold delimiting the panel. lateral lateral, a third pre-fold delimiting the intermediate panel, a fourth pre-fold delimiting the internal side panel, said panel 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 include a longitudinal pre-fold, which can 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 external side panel can be substantially equal to the width of the internal 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 comprise means associated with the flaps and the boxes for keeping the boxes in the raised position when the flaps are in the raised position as well as means for maintaining the flaps facing each other, 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 include a closure panel hinged to the free edge of one of the flaps, this closure panel may include means for attachment to the boxes and to the opposite flap, so as to be able 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 these 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. 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 closure panel may comprise, beyond a pre-fold and from its end opposite the flap on which it is hinged, a folding panel capable of being superimposed on the opposite flap when the closure panel is in the position of closing. The attachment means mentioned may include attachment tabs projecting from the edges of the closure panel, the boxes and the opposite flap being able to include notches capable of cooperating with these attachment tabs.
Enfin, les rabats peuvent être rattachés chacun aux extrémités longitudinales adjacentes des caissons par deux goussets.Finally, the flaps can 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 une languette restant rattachée au reste du panneau par l'une de ses 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 relates to a packaging blank made of sheet material, comprising: a bottom panel; two external side panels connected by a pre-fold to two opposite edges of the bottom panel; two flaps each connected by a pre-fold 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 edges opposite the bottom panel of the two external side panels; two internal side panels each connected by a pre-fold to a respective one of said intermediate panels, at the edge thereof opposite the external side panel, each of these internal side panels extending, in the direction opposite to the intermediate panel , by a fixing flap, these internal side panels further comprising a cutout defining at least one tongue remaining attached to the rest of the panel by one of its ends; a closure panel of dimensions substantially equal to those of the bottom panel and connected by a pre-fold to an edge opposite 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 can 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 external 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 side 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 relates to a method of packaging and wedging an object with a circular outline, this method employing packaging 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. D'autres caractéristiques et avantages de l'invention apparaîtront à la lumière de la description qui va suivre d'un mode de réalisation préféré donné à titre d'exemple non limitatif, description faite en référence aux dessins annexés dans lesquels : - la figure 1 est une vue en perspective d'un emballage selon l'invention ouvert, le verre de lunettes calé étant visible à l'intérieur ;This process involves choosing a packaging - object to be packaged assembly where the bottom panel is a square whose side is substantially equal to the diameter of the glass. Other characteristics and advantages of the invention will appear in the light of the following description of a preferred embodiment given by way of non-limiting example, description made with reference to the accompanying drawings in which: - Figure 1 is a perspective view of an open package according to the invention, the wedged spectacle lens being visible inside;
- la figure 2 est une vue en perspective de l'ensemble de la figure 1 , l'emballage étant refermé ; - la figure 3 est une vue de dessus de l'emballage dans la position de la figure 1 si ce n'est que, pour faciliter la compréhension, les le panneau de fermeture est dans le prolongement du panneau de fond ;- Figure 2 is a perspective view of the assembly of Figure 1, the packaging being closed; - Figure 3 is a top view of the package in the position of Figure 1 except that, to facilitate understanding, the closure panel is in the extension of the bottom panel;
- la figure 4 est une vue d'élévation selon le plan de coupe IV-IV de la figure 3 montrant la coopération des languettes de calage avec le verre de lunettes ;- Figure 4 is an elevational view along the section plane IV-IV of Figure 3 showing the cooperation of the wedging tabs with the spectacle lens;
- la figure 5 est une vue similaire à la figure 4, selon le plan de coupe V-V de la figure 3 ;- Figure 5 is a view similar to Figure 4, along the cutting plane V-V of Figure 3;
- la figure 6 est une vue en perspective partielle représentant un verre de lunettes en place et un caisson, le panneau latéral externe du caisson ayant été partiellement coupé de manière à voir le positionnement des languettes de calage ;- Figure 6 is a partial perspective view showing a spectacle lens in place and a box, the external side panel of the box having been partially cut so as to see the positioning of the wedging tabs;
- la figure 7 est une vue de dessus similaire à la figure 3, les caissons latéraux étant en position rabattue et le verre de lunettes n'étant pas représenté ;- Figure 7 is a top view similar to Figure 3, the side boxes being in the folded position and the spectacle lens not being shown;

- la figure 10 est une vue similaire à la figure 7, les caissons étant aplatis. Sur les figures, les conventions de dessins suivantes ont été adoptées dans un but de clarté :- Figure 10 is a view similar to Figure 7, the boxes being flattened. In the figures, the following drawing conventions have been adopted for clarity:
- les pré-pliures simples sont représentées en traits fins mixtes (par exemple : la pré-pliure 44) ;- the simple pre-folds are shown in thin mixed lines (for example: pre-fold 44);
- les encoches linéaires pratiquées dans le matériau de l'emballage sont représentées en trait continu fort (par exemple 55) ;- the linear notches made in the packaging material are shown in a solid solid line (for example 55);
- les pré-pliures formées de découpes pointillées sont représentées en pointillés forts (par exemple 36). Néanmoins, les conventions précédentes ne s'appliquent pas aux vues en perspective (figures 1 , 2, 6).- The pre-folds formed by dotted cutouts are shown in strong dotted lines (for example 36). However, the above 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 wedging tabs are shown according to this convention only in Figure 8 because of their small size in 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 FIGS. 1 and 3, the package 1 comprises a bottom panel 2, two side boxes 3, two flaps 4, 5 as well as 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 lateral boxes 3 are arranged along two opposite edges 7 of the bottom panel 2, they are identical and extend parallel to one another 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. 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.These boxes 3 also have a triangular section 8 (see Figure 1) which reinforces the rigidity of the structure, which is made from a sheet material such as cardboard. 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. These panels 10, 11, 13 are all three of rectangular 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. 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).The attachment of each box 3 to the bottom panel 2 is carried out 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. Each box 3, consequently formed by a triangular profile 8, is thus movable along the pre-fold 14 between a depressed position in which the external side panel 10 is arranged in the same plane as the bottom panel 2 (Figure 7) and a raised position in which the external side panel 10 is arranged perpendicular 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 box 3 also has an opening 15 made in its internal side panel 13. This opening 15 has a rectangular shape centered on the length of the internal side panel 13, one of the 16 longer edges delimiting it opening flush with the bottom panel 2 and the other 17 longer edges delimiting the opening near the junction 12 of the inner side panel 13 and the intermediate panel 11. This opening 15 is intended for at least partial engagement of a spectacle lens 18 when the boxes 3 are in the raised position, as can be seen in FIG. 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 has been determined as a function of the maximum diameter of the glass 18 and of the shape of the box 3, so as to be preferably large enough to guarantee that the glass 18 comes at most to abut against the edges 19, laterally delimiting the opening, when it is in place in the packaging 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. Ces languettes 20, 21 sont de forme rectangulaire, leur longueur s'étendant sur toute la largeur de l'ouverture 15.Each box 3 further comprises four wedging tongues 20, 21 projecting from the edge 17 delimiting the opening 15 opposite the bottom panel 2. They are articulated according to a pre-fold 22 flush with said edge 17. These tongues 20, 21 are rectangular in 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 tabs 20, located on either side of a median axis, and the two lateral tabs 21, framing the previous ones 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. Les languettes centrales 20, aussi bien que les languettes latéralesThe four wedging tabs 20, 21 of each box 3 are in any case juxtaposed to 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. The central tabs 20, as well as the lateral tabs
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 13.21, are free of any attachment on their longer sides 23 as well as on their side 24 coinciding with the edge 16 delimiting the opening 15 coming close to 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 internal 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 connecting them to the bottom panel 2, the tongues 20, 21 each comprise, along their length, three other pre- transverse folds 25 delimiting each tongue 20; 21 into 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 around an axis 22 coinciding with the edge 17 delimiting the opening 15 opposite the bottom panel 2, this movement allowing the free end 26 to each tab 20; 21 to position themselves on one side or the other of the plane of the internal 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 wedging tongue 20; 21 at the level of the pre-fold 22 connecting it to the internal side panel 13, according to the elastic properties of the sheet material used to make the internal side panel 13 or the tongue 20; 21 (in our example, it is cardboard).
De même, les languettes 20, 21 sont aptes à une déformation élastique suivant chacune des pré-pliures 25 disposées sur leur longueur. 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. 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.Likewise, the tongues 20, 21 are capable of elastic deformation along each of the pre-folds 25 disposed along their length. As regards 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 boxes 3, the latter occupying the other two opposite edges 7 of the bottom panel 2. Visibly in FIG. 9, the bottom panel 2 is thus extended in a star shape, that is to say say from each of its edges 7, 27, 28, by four panels 4, 5, 10, insofar as the flaps 4, 5 are rectangular in 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 the boxes 3, or more precisely the external side panels 10, the flaps 4, 5 are movable between a depressed 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). 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.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 external 10 thus being able to form the sides of a box whose bottom panel 2 forms the bottom (see FIG. 2). In the raised position, the shorter sides 31 of the flaps 4, 5 and the external 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 ;To facilitate this coincidence, four gussets 32 are provided which join each edge 31 of the flaps with the adjacent edge 33 of the external side panel 10. In FIG. 9, showing the blank 34 of the package 1, the panels lateral sides 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 to the external side panel 10 which it connects by two pre -foldings 35, one in the extension of the pre-fold 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 2.30 connecting the flap 4; 5 to the bottom panel 2 and the other in the extension of the pre-fold 14 connecting the external 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 caissonsThe gusset 32 is finally completed by a central pre-fold 36 starting from the corresponding angle 37 of the bottom panel 2 and extending at 45 ° towards the end of the gusset 32. When placing the boxes in the raised position
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.3 and flaps 4, 5, the gussets 32 fold inwards (see Figure 1) and guarantee that when the flaps 4, 5 are held against the boxes 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 fondThe packaging 1 for spectacle lens 18 further comprises a closure panel 6, of dimensions identical to that of the bottom panel
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. 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. 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, 6.2, attached by a pre-fold 38 to the free end of one of the flaps 5, this closure panel 6 thus being 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. 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. A fold-back panel 43 is also provided, projecting beyond a pre-fold 44 of the edge 45 of the closure panel 6 opposite the flap 5 and over 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 fold-back panel 43 is itself extended, on its edge opposite to the closure panel 6, by a third fastening tab 46, along a pre-fold 47, this fastening tab 46 being able to cooperate with a notch 48 formed 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, le 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 encochesThe packaging 1 can thus be maintained in the position of FIG. 2, the boxes 3 and the flaps 4, 5 being in the raised position, the closure panel 6 covering them and the fold-back panel 43 pressing against the flap 4 corresponding. The three tabs 39, 46 inserted in their notches
42, 48 correspondantes permettent de maintenir la cohésion et la rigidité de l'emballage 1 fermé. 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 verre42, 48 correspond to maintain the cohesion and rigidity of the package 1 closed. These elements cooperate to protect and wedge the glass 18 in all directions in space. It can be seen in Figures 1 and 2 that the glass
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 3.18 located inside the packaging 1 is wedged along one of its diametrical axes by the two lateral boxes 3, and along a second of its diametrical axes, perpendicular to the first, by the two flaps 4, 5, the panel bottom 2 and the closure panel 6 taking place on either side of the glass 18, perpendicular to the flaps 4, 5 and boxes 3.
L'emballage 1 est ainsi prêt à être transporté, gerbe ou tout simplement manipulé, sans dommage pour le verre de lunettes 18.The packaging 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.In 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. Les pré-pliures suivantes, pratiquées sur ce panneau central 49, sont destinées à délimiter les parties évoquées :It has a central panel 49 square, each corner of which has undergone two symmetrical cuts. In this central panel 49 are delimited a bottom panel 2, two external side panels 10, two flaps 4, 5 and four gussets 32. The following pre-folds, formed on this central panel 49, are intended to delimit the parts mentioned:
- 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 ;- Two pre-folds 14 connecting the bottom panel 2 to the external side panels 10; - two pre-folds 29, 30 connecting the bottom panel 2 to the flaps 4, 5;
- quatre pré-pliures 35 reliant les panneaux latéraux externes 10 aux goussets 32 ;- Four pre-folds 35 connecting the external side panels 10 to the gussets 32;
- quatre pré-pliures 35 reliant les rabats 4, 5 aux goussets 32. Au niveau de chaque gousset 32, une pré-pliure centrale 36 est ménagée par une ligne de perforation en pointillé.- Four pre-folds 35 connecting the flaps 4, 5 to the gussets 32. At each gusset 32, a central pre-fold 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 comprises, extending from the edge 50 opposite the bottom panel 2 of each external side panel 10, a box panel 51 attached by a pre-fold 9 to said edge 50. Each of these box panels 51 comprises a first 12 and second 52 simple pre-fold successively delimiting an intermediate panel 11, an internal side panel 13 and a fixing flap 53.
Sur le panneau intermédiaire 11 est également ménagée une prépliure 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 provided a pre-fold 54, passing longitudinally through this panel 11 along a median line, this pre-fold 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 side panel 13 receives, for its part, a cutout 15 corresponding to the opening described above consisting of cutting out three sides of a rectangle, one of which coincides with said second pre-fold 52, as well as three cutouts at inside said rectangle and perpendicular to this second pre-fold 52, delimiting four wedging tongues 20, 21 attached by one of their ends to the internal 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 on the other hand formed on each wedging tongue 20, 21 at its connection to the internal side panel 13, as well as three other transverse pre-folds 25 distributed over 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 couvercleThe 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 comprising a pre-fold 44 successively delimiting, from said free edge, a panel of closure 6 and a folding panel 43, the cover panel
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 d§ fond 2 et le rabat opposé 4.56 comprising an attachment tab 39, 46 on each of its free edges: two attachment tabs 39 facing each other intended to cooperate with the two notches 42 formed at the junction 9 of the side panels external 10 and intermediate panels 11, as well as a third attachment tab 46 intended to cooperate with a notch 48 formed 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 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.
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 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.
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.In practice, at the manufacturer of the packaging 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.
L'emballage 1 peut ainsi être avantageusement livré selon des conditionnements dans lesquels les flans 34 encollés et aplatis sont superposés.The packaging 1 can thus advantageously be delivered in 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 user begins by unfolding the intermediate panel 11 and moving the inner side 13 and outer 10 panels away from each other, so as to form the profile. triangular 8 of boxes 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 fondThe packaging 1, then as shown in FIG. 7, is suitable for a packaging process in which the glass 18 is deposited on the bottom panel
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 2.2, then the boxes 3 are raised (see FIGS. 1 and 3), the flaps 4, 5 are folded and the closure panel 6 put in place to result in the closed packaging of FIG. 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 optimum setting of the spectacle lens 18, provision has been made for a package 1 with a bottom panel 2 square with a side approximately equal to the diameter glass 18. The latter is thus inserted into the openings 15 (FIG. 1), pushing the wedging tabs 20, 21 towards the interior of the boxes 3 (FIGS. 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.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.
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.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. In addition, 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.
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 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.
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 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.
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 observed that the 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.
