Abstract

The package is produced by folding a precut blank consisting of side panels (31 - 34) with closure flaps (40, 41) and tabs (38). An internal locking structure which is made up of two panels (45, 46) is connected to the main structure by a triangular strip (42) can be folded to produce a partition which divides the package diagonally into two compartments. This has reinforcing components (57) at the bottom. An Independent claim is included for the blank.

Description

La présente invention concerne le domaine technique de l'emballage et du conditionnement de produits divers dans un étui formé par pliage d'un flan prédécoupé de carton ou analogue.The present invention relates to the technical field of packaging and packaging of various products in a case formed by folding a blank pre-cut from cardboard or the like.

Les étuis utilisés présentent, généralement, une forme sensiblement parallélépipèdique qui, si elle est à même de contenir le produit à conditionner, n'est pas toujours susceptible de procurer à ce dernier un calage suffisant pour en préserver l'intégrité.The cases used generally have a substantially shaped parallelepipedic which, if it is able to contain the product to be packaged, is not not always likely to provide the latter with sufficient wedging to preserve it integrity.

Afin de tenir compte de la forme particulière du contenant, l'étui doit donc comprendre une structure interne de calage qui définit alors un logement d'accueil pour le produit à conditionner.In order to take into account the particular shape of the container, the case must therefore understand an internal wedging structure which then defines a reception accommodation for the product to be packaged.

Tel est, par exemple, le cas pour le conditionnement d'un tube réalisé à partir d'une gaine en matière déformable et fermé par le fond, de sorte que le tube présente, au niveau de son embouchure, une forme sensiblement cylindrique qui va en s'aplatissant pour présenter à l'extrémité opposée une forme sensiblement prismatique. En effet, pour assurer un calage efficace d'un tel tube, il est nécessaire de disposer d'un logement d'accueil en forme de coin ou de prisme.This is, for example, the case for the packaging of a tube produced at from a sheath of deformable material and closed at the bottom, so that the tube has, at its mouth, a substantially cylindrical shape which goes flattening to present at the opposite end a substantially prismatic shape. Indeed, to ensure an effective wedging of such a tube, it is necessary to have a corner or prism-shaped accommodation unit.

La présence de logements en coin peut également s'avérer utile pour le conditionnement, par exemple, de produits en sachets qui présentent une extrémité plus épaisse que l'autre.The presence of corner housing can also be useful for the packaging, for example, of products in sachets which have one end thicker than the other.

Afin de répondre à ce besoin, le brevet US 3 370 776 et le modèle d'utilité DE 299 02 027 ont tous deux proposé un étui de conditionnement réalisé à partir d'un flan prédécoupé de carton compact. Cet étui de conditionnement est monté par pliage pour comporter une enveloppe périphérique à panneaux articulés destinés à former un corps d'étui sensiblement parallélépipèdique, des volets et des rabats de fermeture des extrémités transversales du corps. L'étui comprend, également, une structure interne de calage formant un prolongement rabattable et contre-fixable et comportant une bande de liaison, un panneau médian et un contre-panneau, délimités et articulés entre eux par des lignes de pliage orientées de manière que le panneau médian s'étende en diagonale dans le corps d'étui et délimite deux compartiments sensiblement en forme de coins.In order to meet this need, US Pat. No. 3,370,776 and the utility model DE 299 02 027 both proposed a packaging case made from a blank precut from compact cardboard. This packaging case is mounted by folding to include a peripheral envelope with hinged panels intended to form a body of substantially parallelepipedic case, flaps and flaps closing the transverse ends of the body. The case also includes an internal structure wedging forming a folding and counter-fixed extension and comprising a connecting strip, a middle panel and a counter panel, delimited and articulated between them by fold lines oriented so that the middle panel extends in diagonal in the case body and delimits two substantially shaped compartments corners.

Selon ces deux documents, la bande de liaison et le contre-panneau sont articulés sur deux parties opposées du panneau médian, de sorte que la bande de liaison et le contre-panneau se trouvent repliés selon deux directions opposées pour être disposés chacun dans un compartiment distinct.According to these two documents, the connecting strip and the counter-panel are articulated on two opposite parts of the middle panel, so that the strip of connection and the counter-panel are folded in two opposite directions to each be arranged in a separate compartment.

Or, il est apparu, à l'usage, qu'un tel étui ne présentait pas toujours une résistance optimale à l'écrasement sous l'effet d'un effort exercé perpendiculairement aux grandes faces de l'étui.However, it appeared, in use, that such a case did not always present a optimal resistance to crushing under the effect of a force exerted perpendicularly the large sides of the case.

L'art antérieur connaít ainsi l'enseignement fourni par le brevet US 2 893 623, selon lequel le prolongement, évoqué précédemment, comporte une bande de liaison et un contre-panneau qui sont orientés dans la même direction et dans le même sens par rapport au panneau médian de manière à être tous deux, après pliage, orientés dans le même sens afin de venir renforcer la résistance à l'écrasement de l'un des compartiments.The prior art thus knows the teaching provided by the patent US 2,893,623, according to which the extension, mentioned above, comprises a connecting strip and a counter panel which are oriented in the same direction and in the same direction with respect to the middle panel so as to be both, after folding, oriented in the same direction in order to reinforce the resistance to the crushing of one of the compartments.

Une telle construction est satisfaisante sur ce plan mais elle pêche par un défaut de renforcement du fond du compartiment renforcé et/ou du compartiment opposé.Such a construction is satisfactory in this respect, but it fishes by a failure to reinforce the bottom of the reinforced compartment and / or the compartment opposite.

Afin de remédier à cet inconvénient, il est donc apparu le besoin de disposer d'un étui de conditionnement, du type ci-dessus, qui présente des qualités de résistance à l'écrasement renforcées et qui, plus particulièrement, offre, pour l'un au moins de ses compartiments en forme de coin, une résistance à l'écrasement optimale, au droit de son fond, de manière à définir, au sein de l'étui, un compartiment renforcé particulièrement résistant à l'écrasement.In order to remedy this drawback, it therefore appeared the need to have a packaging case, of the above type, which has qualities of resistance to crushing reinforced and which, more particularly, offers, for one to less of its wedge-shaped compartments, resistance to crushing optimal, in line with its substance, so as to define, within the case, a reinforced compartment particularly resistant to crushing.

Pour atteindre cet objectif, l'invention concerne un étui de conditionnement selon la revendication 1, réalisé à partir d'un flan prédécoupé et monté par pliage. To achieve this objective, the invention relates to a case of packaging according to claim 1, produced from a pre-cut blank and mounted by folding.

L'invention vise, également, un flan prédécoupé selon la revendication 12 pour la réalisation de l'étui ci-dessus.The invention also relates to a precut blank according to claim 12 for the production of the case above.

Selon une première forme de réalisation, l'étui conforme à l'invention est réalisé à partir d'un flan prédécoupé, désigné dans son ensemble par la référence 30 et illustré à la fig. 1 sur laquelle les lignes de coupe sont représentées en trait plein, tandis que les lignes de pliage sont illustrées en trait mixte. Le flan 30 peut être réalisé en tout matériau approprié et, de préférence mais non exclusivement, en carton compact.According to a first embodiment, the case according to the invention is produced from a precut blank, generally designated by the reference 30 and illustrated in FIG. 1 in which the cutting lines are shown in solid lines, while the fold lines are shown in phantom. The blank 30 can be made of any suitable material and preferably, but not exclusively, of compact cardboard.

Le flan prédécoupé 30 comprend une première partie I, dite d'enveloppe périphérique, destinée à former, par pliage, le corps de l'étui. Cette première partie I comporte, notamment, quatre panneaux 31 à 34 articulés, les uns à la suite des autres, par des lignes de pliage parallèles 35 à 37. Les panneaux, 31 et 33, sont prolongés en bout par des rabats repliables 38, tandis que les deux autres panneaux, 32 et 34, sont pourvus chacun d'un volet de fermeture 40 et 41 des extrémités du corps d'étui, respectivement haute et basse en considération de l'orientation de la fig. 1.The precut blank 30 comprises a first part I , called the peripheral envelope, intended to form, by folding, the body of the case. This first part I comprises, in particular, four panels 31 to 34 articulated, one after the other, by parallel fold lines 35 to 37 . The panels, 31 and 33 , are extended at the end by folding flaps 38 , while the other two panels, 32 and 34 , are each provided with a closing flap 40 and 41 of the ends of the case body, respectively high and low in consideration of the orientation of fig. 1 .

Le flan 30 comprend, également, une seconde partie II, dite de structure interne de calage, qui est constituée, notamment, d'une bande de liaison 42 s'étendant dans le prolongement du dernier panneau articulé 34. La bande de liaison 42 est reliée au dernier panneau 34 par une ligne de pliage 43 parallèle à celle 37 séparant le dernier panneau 34 du panneau adjacent 33. The blank 30 also includes a second part II , called an internal wedging structure, which is made up, in particular, of a connecting strip 42 extending in the extension of the last articulated panel 34 . The connecting strip 42 is connected to the last panel 34 by a fold line 43 parallel to that 37 separating the last panel 34 from the adjacent panel 33.

La partie de structure interne II comprend aussi un panneau médian 45 et un contre-panneau 46 qui s'étendent à partir de la bande de liaison 42 en étant délimités par deux lignes de pliage 47 et 48 parallèles entre elles. Les deux lignes de pliage 47 et 48 forment, en outre, un angle de valeur α avec la ligne de pliage 43.The internal structural part II also includes a middle panel 45 and a counter panel 46 which extend from the connecting strip 42 , being delimited by two fold lines 47 and 48 parallel to each other. The two fold lines 47 and 48 also form an angle of value α with the fold line 43 .

La ligne 48 s'étend sur toute la longueur du panneau 45, tandis que la ligne 47 aboutit à une découpe 47a séparant en partie basse ledit panneau de la bande 42.Line 48 extends over the entire length of panel 45 , while line 47 leads to a cutout 47a separating said panel from the strip 42 at the bottom .

Ainsi, la bande de liaison 42 et le contre-panneau 46 s'étendent dans le même sens à partir de l'extrémité haute du prolongement II en étant, dans l'exemple illustré, tous deux prolongés au delà du bord transversal 49 du panneau médian.Thus, the connecting strip 42 and the counter panel 46 extend in the same direction from the upper end of the extension II , being, in the example illustrated, both extended beyond the transverse edge 49 of the panel median.

La mise en forme de l'étui selon l'invention, à partir du flan 30, s'effectue par pliage successif, le long des lignes 47 et 48, de la partie II du flan dans, respectivement, le sens des flèches F1 et F2 , puis par un pliage successivement le long des lignes 35, 36, 37 et 43 de la partie I d'enveloppe périphérique, de manière à venir fixer le premier panneau articulé 31 contre la bande de liaison 42 par tout moyen approprié, tel que, par exemple, par collage. Shaping of the case according to the invention, from the blank 30 , is carried out by successive folding, along lines 47 and 48, of part II of the blank in, respectively, the direction of the arrows F 1 and F 2 , then by successively folding along the lines 35, 36, 37 and 43 of the part I of the peripheral envelope, so as to fix the first articulated panel 31 against the connecting strip 42 by any appropriate means, such as, for example, by bonding.

Le contre-panneau 46 présente, à l'opposé de la ligne 48, un bord d'appui 50 qui vient se placer dans l'angle défini par la ligne de pliage 37. Il doit être noté que le bord 50 définit, avec la ligne de pliage 48, un angle de même valeur α que celle de l'angle défini par les lignes de pliage 47 et 43. La valeur α de cet angle, correspond à l'inclinaison du panneau médian 45 à l'intérieur du corps d'étui défini par les panneaux articulés 31, 32, 33 et 34.Against the panel 46 has, opposite the line 48 , a bearing edge 50 which is placed in the angle defined by the fold line 37 . It should be noted that the edge 50 defines, with the fold line 48, an angle of the same value α as that of the angle defined by the fold lines 47 and 43. The value α of this angle corresponds to the inclination of the middle panel 45 inside the case body defined by the articulated panels 31, 32, 33 and 34 .

De plus, selon l'invention, la ligne de pliage 48 et le bord d'appui 50 convergent vers le bas, tout comme les lignes de pliage 43 et 47. Selon l'exemple illustré, le contre-panneau 46 s'étend jusqu'en partie basse du panneau médian. Toutefois, le contre-panneau 46 pourrait n'intéresser qu'une partie du panneau médian 45 en étant, de préférence mais non exclusivement, lié à la partie haute de ce dernier.In addition, according to the invention, the fold line 48 and the support edge 50 converge downwards, just like the fold lines 43 and 47 . According to the example illustrated, the counter panel 46 extends to the lower part of the middle panel. However, the counter-panel 46 could only interest a part of the middle panel 45 by being, preferably but not exclusively, linked to the upper part of the latter.

Après montage, la bande de liaison 42 se trouve contre le premier panneau 31, tandis que le contre-panneau 46 se trouve contre le troisième panneau 33.After assembly, the connecting strip 42 is located against the first panel 31 , while the counter panel 46 is located against the third panel 33 .

L'étui ainsi formé est illustré en perspective à la fig. 2 de laquelle il ressort que le panneau médian 45 s'étend en diagonale dans le corps d'étui. La position inclinée du panneau médian 45, montrée clairement sur la fig. 3, définit, dans le corps d'étui, un premier compartiment 51 et un second compartiment 52 de forme sensiblement prismatique ou en coin opposés l'un à l'autre.The case thus formed is illustrated in perspective in FIG. 2 from which it appears that the middle panel 45 extends diagonally in the case body. The inclined position of the middle panel 45 , shown clearly in FIG. 3 , defines, in the case body, a first compartment 51 and a second compartment 52 of substantially prismatic shape or at a corner opposite one another.

La fig. 4 montre que, selon l'invention, la bande de liaison 42 et le contre-panneau 46 sont orientés dans la même direction et le même sens par rapport au panneau médian et sont tous deux disposés dans le compartiment en coin 51 pour le renforcer contre les pressions selon les flèches F3 et F4 . Fig. 4 shows that, according to the invention, the connecting strip 42 and the counter panel 46 are oriented in the same direction and the same direction relative to the median panel and are both arranged in the corner compartment 51 to reinforce it against the pressures according to arrows F 3 and F 4 .

Selon une autre caractéristique de l'invention, le panneau médian 45 présente, au niveau de son extrémité basse, une patte 57 de fixation contre la face interne du dernier panneau articulé 34.According to another characteristic of the invention, the median panel 45 has, at its lower end, a lug 57 for fixing against the internal face of the last articulated panel 34 .

De manière préférée, cette patte de fixation 57 est reliée au panneau médian 45 par une bande d'articulation 58 définie par deux lignes de pliage 59 et 60, non parallèles entre elles et convergeant en direction de la bande de liaison 42. Les lignes 59 et 60 définissent avantageusement un angle α' de même valeur que l'angle α. Cette bande d'articulation 58 permet de définir une sorte de soufflet qui autorise une présentation à plat de l'étui préformé, la patte 57 étant fixée contre le dernier panneau 34 et le premier panneau 31 étant fixé sur la bande de liaison 42. La bande d'articulation 58, formant soufflet, permet, en effet, un déplacement de la structure interne de calage lors du passage de cet état préformé à plat à l'état définitif de l'étui, tel qu'illustré à la fig. 2.Preferably, this fixing lug 57 is connected to the middle panel 45 by an articulation band 58 defined by two fold lines 59 and 60 , not parallel to each other and converging in the direction of the connecting band 42 . Lines 59 and 60 advantageously define an angle α 'of the same value as the angle α. This articulation band 58 makes it possible to define a sort of bellows which allows a flat presentation of the preformed case, the tab 57 being fixed against the last panel 34 and the first panel 31 being fixed on the connecting band 42 . The articulation band 58 , forming a bellows, allows, in effect, a displacement of the internal wedging structure during the passage from this preformed state flat to the final state of the case, as illustrated in FIG. 2 .

Selon l'exemple illustré, la patte 57 est fixée sur le panneau 34 en étant orientée vers le bas, mais il pourrait également être envisagé de fixer cette patte 57 de manière qu'elle soit orientée vers le haut de l'étui et située dans le compartiment 51. Une telle orientation vers le haut est notamment préférée dans le cas d'une automatisation du montage de l'étui.According to the example illustrated, the tab 57 is fixed to the panel 34 while being oriented downwards, but it could also be envisaged to fix this tab 57 so that it is oriented towards the top of the case and located in compartment 51 . Such an upward orientation is particularly preferred in the case of automating the mounting of the case.

Les fig. 5 à 7 illustrent une variante de réalisation de l'étui conforme à l'invention, selon laquelle le flan 30, comporte des volets de fermeture 40 et 41 qui sont disposés dans le prolongement du même panneau articulé 32. Figs. 5 to 7 illustrate an alternative embodiment of the case according to the invention, according to which the blank 30 comprises closing flaps 40 and 41 which are arranged in the extension of the same articulated panel 32 .

Par ailleurs, le bord supérieur 61 de la bande de liaison 42, le bord supérieur 62 du panneau médian 45 et le bord supérieur 63 du contre-panneau 46 sont situés dans le prolongement les uns des autres, de sorte qu'après formation de l'étui, les bords supérieur 61, 62 et 63 se trouvent sensiblement au même niveau, comme le montre plus particulièrement la fig. 6.Furthermore, the upper edge 61 of the connecting strip 42 , the upper edge 62 of the middle panel 45 and the upper edge 63 of the counter panel 46 are located in the extension of each other, so that after formation of the 'case, the upper edges 61, 62 and 63 are located substantially at the same level, as shown more particularly in FIG. 6 .

Selon cette variante, le panneau médian 45 présente une découpe 64 qui définit une empreinte d'immobilisation ou un alvéole de réception d'un produit unitaire conditionné 65, tel que, par exemple, un flacon qui se trouve alors disposé, à la fois dans les deux compartiments en coins 51, 52.According to this variant, the middle panel 45 has a cutout 64 which defines an immobilization imprint or a cell for receiving a unitary conditioned product 65 , such as, for example, a bottle which is then placed, both in the two corner compartments 51, 52 .

De manière préférée, la découpe 64 définit un volet 66 rabattable, articulé par une ligne de pliage 67 sur le panneau médian 45. Le volet rabattable comporte dans sa partie médiane une ligne de coupe brisée 68 qui définit une patte 69 bordée par deux demi-lignes de pliage 691 alignées avec lesquelles elle divise le volet 66 en deux parties 66a et 66b. Lors de la mise en forme de l'étui, la partie 66b est placée en appui, voire contrefixée sur le panneau 32 alors que la partie 66a définit un support pour le produit 65 placé dans l'alvéole, de manière à maintenir ledit produit 65 à distance du volet de fond de l'étui, comme le montre la fig. 7 et constitue en même temps un moyen de remplacement du fond du compartiment 51. Preferably, the cutout 64 defines a foldable flap 66 , articulated by a fold line 67 on the middle panel 45 . The folding flap has in its middle part a broken cutting line 68 which defines a tab 69 bordered by two half-fold lines 69 1 aligned with which it divides the flap 66 into two parts 66a and 66b . During the shaping of the case, the part 66b is placed in abutment, or even fixed on the panel 32 while the part 66a defines a support for the product 65 placed in the cell, so as to maintain said product 65 away from the bottom flap of the case, as shown in fig. 7 and at the same time constitutes a means of replacing the bottom of the compartment 51.

Les fig. 8 et 9 illustrent une autre forme de réalisation selon laquelle le contre-panneau 46 présente, à l'opposé du panneau médian 45, une contre-patte de renfort 70 qui est séparée du contre-panneau 46 par une ligne de pliage 71 parallèle au bord d'appui 50 et située dans le prolongement de ce dernier. La ligne de pliage 71 définit alors, avec la ligne de pliage 48, un angle α. La contre-patte de renfort 70 est, de préférence, reliée au contre-panneau 46 en partie basse de ce dernier, vers le point de convergence des lignes de pliage 48 et 71. La contre-patte de renfort 70 définit un bord d'appui 72 parallèle au bord d'appui 50. La fonction de ce bord d'appui 72 apparaítra par la suite. Figs. 8 and 9 illustrate another embodiment according to which the counter panel 46 has, opposite the median panel 45 , a reinforcing lug 70 which is separated from the counter panel 46 by a fold line 71 parallel to the support edge 50 and located in the extension of the latter. The fold line 71 then defines, with the fold line 48, an angle α. The reinforcing lug 70 is preferably connected to the counter panel 46 in the lower part of the latter, towards the point of convergence of the fold lines 48 and 71 . The reinforcing lug 70 defines a support edge 72 parallel to the support edge 50 . The function of this support edge 72 will appear later.

Afin d'assurer un renfort de la pointe du coin correspondant au fond du compartiment 51, le flan 30 présente, également, un prolongement rabattable III destiné à constituer une structure interne de renfort. Selon l'exemple illustré à la fig. 8, le prolongement de renfort III s'étend en partie basse du dernier panneau articulé 34, à partir d'une ligne de pliage 73 perpendiculaire aux lignes de pliage 37 et 43. Le prolongement de renfort III comprend alors, à partir de la ligne de pliage 73, une bande de contre-collage 74 et un volet de renfort 75 séparé de la bande de contre-collage 74 par une ligne de pliage 76 parallèle à la ligne de pliage 73. In order to provide reinforcement for the corner point corresponding to the bottom of the compartment 51, the blank 30 also has a folding extension III intended to constitute an internal reinforcement structure. According to the example illustrated in FIG. 8, the reinforcement extension III extends in the lower part of the last articulated panel 34, from a fold line 73 perpendicular to the fold lines 37 and 43 . The reinforcement extension III then comprises, from the fold line 73 , a lamination strip 74 and a reinforcement flap 75 separated from the lamination strip 74 by a fold line 76 parallel to the line of folding 73.

Le flan prédécoupé, ainsi constitué, est mis en forme comme dit précédemment de manière à constituer l'étui conforme à l'invention. Après formation des lignes de pliage 43, 47 et 48, le prolongement de renfort III est rabattu et la bande de contre-collage 74 est collée contre la face interne du dernier panneau articulé 34. La contre-patte de renfort 70 est rabattue sur le contre-panneau 46, par la formation de la ligne 71 dont le pliage est effectué de manière que, après la mise en forme de l'étui, comme illustré à la fig. 9, la contre-patte de renfort 70 soit plaquée contre le panneau articulé 33 et que son bord 72 soit en appui contre le panneau 32 dans l'angle formé par la ligne de pliage 36.The precut blank, thus formed, is shaped as said above so as to constitute the case according to the invention. After the fold lines 43, 47 and 48 have been formed, the reinforcement extension III is folded down and the lamination strip 74 is glued against the internal face of the last articulated panel 34 . The reinforcing lug 70 is folded down on the counter panel 46, by the formation of the line 71 , the folding of which is carried out so that, after the shaping of the case, as illustrated in FIG. 9 , the reinforcing lug 70 is pressed against the articulated panel 33 and its edge 72 is in abutment against the panel 32 in the angle formed by the fold line 36 .

Ainsi, la contre-patte 70 renforce la partie basse du compartiment 51 et les faces triangulaires correspondant aux panneaux 31 et 33 du compartiment 52. De plus, la contre-patte 70 assure ainsi une immobilisation et un calage du contre-panneau 46 contribuant au bon positionnement du panneau médian 45.Thus, the lug 70 reinforces the lower part of the compartment 51 and the triangular faces corresponding to the panels 31 and 33 of the compartment 52 . In addition, the lug 70 thus ensures immobilization and wedging of the counter panel 46 contributing to the correct positioning of the middle panel 45 .

En position fermée de l'étui, le volet de renfort 75 est alors appliqué contre le panneau médian 45, comme le montre la fig. 9. In the closed position of the case, the reinforcing flap 75 is then applied against the middle panel 45 , as shown in FIG. 9 .

Ainsi, la bande de contre-collage 74 et le volet de renfort 75, plaqué contre le panneau médian 45, assurent une fermeture du fond du compartiment 51 et renforcent la résistance de ce dernier.Thus, the lamination strip 74 and the reinforcing flap 75 , pressed against the middle panel 45 , ensure that the bottom of the compartment 51 is closed and reinforce the resistance of the latter.

La mise en oeuvre du prolongement de renfort III et de la contre-patte de renfort 70 contribuent à assurer une très bonne résistance du compartiment 51, de manière à protéger convenablement un produit 77 en forme de coin, tel que par exemple un tube qui y serait introduit. L'étui, ainsi réalisé, présente une très bonne résistance aux chocs et aux chutes. En effet, la bande de contre-collage 74 et le volet de renfort 75, ainsi que la contre-patte de renfort 70, évitent que la pointe du produit 77 soit projetée contre le fond de l'étui et endommagée.The implementation of the reinforcement extension III and the reinforcement lug 70 contribute to ensuring very good resistance of the compartment 51, so as to adequately protect a product 77 in the form of a wedge, such as for example a tube which would be introduced. The case, thus produced, has very good impact and drop resistance. Indeed, the lamination strip 74 and the reinforcement flap 75 , as well as the reinforcement lug 70 , prevent the tip of the product 77 from being thrown against the bottom of the case and damaged.

La mise en oeuvre du prolongement de renfort III et de la contre-patte de renfort 70 offrent, avantageusement, une bonne tenue aux chocs de la partie en coin définissant le fond du compartiment 51.The use of the reinforcement extension III and of the reinforcement lug 70 advantageously offer good impact resistance of the corner part defining the bottom of the compartment 51 .

Les fig. 10 à 12 illustrent une autre variante de réalisation. Figs. 10 to 12 illustrate another alternative embodiment.

Le prolongement rabattable de renfort III, qui s'étend à partir de la ligne de pliage 73, comprend un volet de renfort 78 articulé. Ce volet comporte une patte d'appui 79 qui s'étend à partir d'une ligne de pliage 80 sensiblement parallèle à la ligne de pliage 43 et perpendiculaire à la ligne de pliage 73. La patte d'appui 79 présente alors un bord d'appui 81 parallèle aux bords d'appui 50 et 72. Le bord d'appui 81 définit, avec la ligne de pliage 80, un angle α.The folding reinforcement extension III , which extends from the fold line 73, comprises a hinged reinforcement flap 78 . This flap has a support tab 79 which extends from a fold line 80 substantially parallel to the fold line 43 and perpendicular to the fold line 73. The support tab 79 then has an edge d support 81 parallel to support edges 50 and 72 . The bearing edge 81 defines, with the fold line 80, an angle α.

Lors de la mise en forme de l'étui, conformément aux séquences de pliage et de collage présentées précédemment, le volet 78 est replié contre le panneau 45 et la ligne de pliage 80 est formée de manière que, lors de la mise en forme de l'étui, la patte d'appui 79 soit placée contre le panneau articulé 31 et le bord 81 en appui contre le panneau 32 dans l'angle défini par la ligne de pliage 35. Par cette disposition, la partie basse du panneau médian 45, formant le coin définissant le fond du compartiment 51, se trouve parfaitement calée, d'une part, par le prolongement de renfort III ainsi constitué et, d'autre part, par la contre-patte de renfort 70 qui immobilise le contre-panneau 46 et donc le panneau médian 45.During the shaping of the case, in accordance with the folding and gluing sequences presented above, the flap 78 is folded against the panel 45 and the fold line 80 is formed so that, during the shaping of the case, the support tab 79 is placed against the articulated panel 31 and the edge 81 bears against the panel 32 at the angle defined by the fold line 35 . By this arrangement, the lower part of the median panel 45 , forming the corner defining the bottom of the compartment 51, is perfectly wedged, on the one hand, by the reinforcement extension III thus formed and, on the other hand, against reinforcement tab 70 which immobilizes the counter panel 46 and therefore the middle panel 45 .

Cette disposition avantageuse de l'invention permet alors d'assurer une bonne résistance mécanique de la pointe du compartiment 51 et donc une bonne protection d'un produit conditionné qui y serait placé. This advantageous arrangement of the invention then makes it possible to ensure good mechanical strength of the tip of the compartment 51 and therefore good protection of a packaged product which would be placed there.

Les fig. 13 à 16 illustrent d'autres variantes de réalisation de l'étui conforme à l'invention selon lesquelles le maintien de la pointe du compartiment 51 est effectué par une patte de maintien 85 s'étendant au niveau de l'extrémité basse du panneau médian 45, à partir d'une ligne de pliage 86 perpendiculaire à la ligne 48. Comme le montrent plus particulièrement les fig. 14 et 16, la patte de maintien 85 est destinée, lors de la mise en forme de l'étui, à venir en appui, par son bord 87 opposé à la ligne de pliage 86, contre le panneau 32 pour ainsi empêcher un écartement trop important, par rapport au panneau 34, du bas du panneau médian 45, au niveau de la pointe du compartiment 51. Figs. 13 to 16 illustrate other alternative embodiments of the case according to the invention according to which the retention of the tip of the compartment 51 is carried out by a retaining tab 85 extending at the level of the lower end of the middle panel 45 , from a fold line 86 perpendicular to the line 48 . As shown more particularly in FIGS. 14 and 16 , the retaining tab 85 is intended, during the shaping of the case, to come into abutment, by its edge 87 opposite the fold line 86 , against the panel 32 so as to prevent excessive separation important, relative to the panel 34 , from the bottom of the middle panel 45 , at the point of the compartment 51 .
