Definitions

  • the present invention relates to display boxes, in particular display boxes for the packaging and presentation of luxury items such as perfumery.
  • Boxes and boxes are already known having a base and a two-piece cover, comprising pivoting members, for example lugs and holes, making it possible to pivot the cover relative to the base.
  • patent in the United States of America No. 2491 264 shows a box whose cover is encased around the base when it is in the closed position, lugs being provided in the cover and corresponding oblong holes in the base, to allow that the opening of the box is not hampered from the start by the stop on the rear face of the side wall of the cover against the corresponding face of the base; thus, in the closed position, the pins occupy the upper part of the oblong holes, which is furthest from the rear face of the side wall of the box; as the box opens, under the effect of pressure on the back of the cover or the weight of it, the pins descend into the oblong holes, that is to say that the cover descends relative to the base, which, taking into account the inclination of the longitudinal axis of the oblong holes, simultaneously causes the recoil of the cover and allows the rear face of its side wall to bypass the obstacle constituted by that of the base, that is to say of tipping under it.
  • the opening of a box of this type requires denc to lift the rear part of the base well before the cover has reached its position of opening to 90 degrees; when the box is placed on a horizontal support and its cover is open 90 degrees to this support, it is not itself horizontal, because of the presence, under its base, of the rear face of the cover , which can in some cases be a disadvantage; it is also impossible, the box being open on a support, to grasp it by its base or by its cover without seeing it suddenly change opening position (with all the unfortunate consequences that may result), the position of stable opening being not that in which the box rests on its support (the cover is then supported on it), but that in which the rear face of the cover is supported against the base of the base; moreover, it is not necessary that in the closed position this rear face covers that of the base up to the base thereof, so that it is not necessary to raise the rear of the base from the start of the movement d 'opening the cover; this results in this closed position, the presence of a shoulder at the rear of the box, preventing easy automatic packaging
  • French Patent No. 1,142,823 relates to a box comprising a base and a two-piece cover, the cover of which is pivotally mounted on the base not by means of lugs and oblong holes, but, conventionally, by means of a line creasing forming hinge formed between the cover and a tongue in one piece with it and which is also fixed to the base which has a base forming a lower peripheral rim for this base on three sides.
  • This type of embodiment is extremely fragile at the hinge, the crease line constituting an area of least resistance requested at each opening and closing operation of the box, even when it is "reinforced" by a sheet of dressing; the risks of deterioration by tearing of the hinge are all the more important that the tongue is glued to the upper part of the base, which implies that when the base is placed on a substantially horizontal surface, the cover being open to 90 degrees by resting on the same surface, the hinge is constantly stressed; grabbing the box by its base or its cover also causes a sudden change in the open position, which can be as damaging to the box (at the hinge) as to its content.
  • Patent in the United States of America No. 2,880,858 also shows a box comprising a base and a two-piece cover, the cover of which is pivotally mounted on the base by means of lugs of circular external shape and also circular holes. ; in order to facilitate the pivoting of the cover relative to the base, the shapes of these two parts are relatively complicated; in particular, in the closed position, at the front of the box, the cover penetrates inside the base, while at the rear of the box, the cover is always outside the base. Again, it is impossible to open the cover 90 degrees without lifting the back of the box.
  • the invention aims to remedy these drawbacks and create a display box having a neat appearance and good robustness, while remaining easy to manufacture and low cost, thanks in particular to the possibility of manufacturing the box using machines with a minimum of manual intervention.
  • the invention relates to a display case of the type comprising a base adapted to receive an article to be presented and provided with a side wall, and a hollow cover, the base and the cover being constituted by two separate parts, the cover being pivotally mounted on an end face of the side wall of the base between a closed position where it surrounds said side wall and an open position where it partially releases the base by revealing the article presented, thanks to pivoting members comprising on the one hand two projecting lugs integral with one of said parts and on the other hand two ovalized holes for receiving said lugs and formed in the other of said parts, display case characterized in that the base has a lower peripheral rim connected to the lower part of its lateral apron, on which the cover rests in the closed position, and an opening in the region of said end face of the lateral wall a u at least in the vicinity of said flange, to avoid blocking of the cover by the side wall of the base before it has reached its open position.
  • This structure makes it possible to obtain the desired advantages and an easy operation
  • the two protruding pins are integral with the base, and the two holes are formed in the cover.
  • the base comprises a base provided with a side wall having an opening in the region of an end face and a lower peripheral rim, and a frame provided with a side wall having two protruding lugs and also an opening and an upper rim folded inwards, the side wall of the frame surrounding the side wall of the base, as well as a plate provided with at least one light forming a receptacle for the article to be presented, said plate being held at the upper part of the base between support means such as vertical ribs integral with the inner part of the side wall of the base and the upper edge of the frame, while the cover comprises an inner element provided with holes having an ovalization and intended to receive the lugs of the base, the thickness of which is at least approximately equal to the length of the lugs of the base, and an outer element rec opening the inner wall element and which is full at the end of the holes.
  • the display case of the invention shown diagrammatically in FIGS. 1 and 2, comprises a base 1 intended to receive an article to be presented and a hollow cover 2, formed in the form of two separate parts.
  • the base 1 itself comprises a base plate 11 and a side wall 12 placed on the base plate 11, and of dimensions slightly smaller than it is, so that is determined on the periphery of the base plate 11 , a peripheral rim 13; the base plate is here rectangular, and the general shape of the side wall is therefore also rectangular; near one of the ends of the side wall 12, there are two pins 14 projecting towards the outside of the wall respectively on one side and the other of the base; these two pins 14, here cylindrical, placed near an end face 121 of the side wall 12, are located in the extension of one another to determine an axis around which the cover 2 is pivotally mounted relative to the base 1, between a closed position where it rests on the peripheral rim 13 by surrounding the side wall 12 (that is to say where it closely covers the base 1) and an open position where it reveals the article presented and where for this it releases the base 1, except in the region of the pivot axis.
  • the cover 2 has a top 21 and a side wall 22 which, being intended in the closed position to tightly cover the base 1, has the same general shape as the side wall 12 of said base, with internal dimensions barely greater than the external dimensions of this side wall 12; in order to receive the projecting lugs of the side wall 12 of the base 1, the side wall 22 of the cover 2 has two holes 23.
  • an appropriate means may consist in that this pivoting is not reduced to a simple rotation, but consists of a rotation accompanied by a slight translation of the two parts relative to one another.
  • an appropriate means may consist in that the wall lateral 12 of the base 1 has an opening in the region of the end face 121, at least in the vicinity of the peripheral rim 13.
  • the translation accompanying the rotation of the cover 1 relative to the base 2 is obtained by an ovalization of the holes 23, the axis of the oval being inclined towards the case and towards the front of the display case when the latter is in the closed position, the cover 2 resting on the base 1; the opening in the region of the end face 121 is situated over its entire length, at its lower part, and extends to the rear part of the two faces of the side wall 12 of the base 1 which are attached thereto ; in order to stop the movement of the cover 2 at a limit open position, it is possible to provide on each of the two faces where the opening extends, a stop edge 122 for the lower edge 221 of the side wall 22 of the cover 2 ; so that this open position is stable even when the cabinet is tilted, it can also be provided that the width of the faces at this location is greater than an appropriate minimum value.
  • the cover 2 being provided in a relatively flexible material, the mounting of the cover 2 on the base 1 is done simply by force, by spreading its side wall 22 and letting the side wall resume its shape when the pins 14 are engaged in said holes 23 ; the box is opened by making the cover 2, at the same time as a rotation relative to the base 1, a slight upward translation.
  • the base 1 is constituted by a base 1A, a plate 1B, and a frame 1C.
  • the base 1A comprises a base plate 11A and a side wall 12A having here a generally rectangular configuration, but having only three faces only, the location of the fourth face being completely freed by the opening intended to allow opening the safe; in addition, the two faces delimiting the location of the removed end face each have a notch thus extending the opening along these two faces at their lower part, this notch being limited by a stop song 122A.
  • the external dimensions of the side wall 12A being smaller than those of the base plate 11A, the base has a peripheral rim 13A preferably having the width of the cover thickness so that there is no projecting part .
  • the side wall 12A also comprises vertical ribs 15A secured to its interior part and to the base plate 11A; these vertical ribs, intended to support the plate 1B, may extend for example perpendicular to the face to which they are integral.
  • the base 1A can be of any relatively rigid material, but for most applications, plastics or cardboard are particularly suitable, in particular polystyrene, having regard to the low manufacturing cost which they imply; this part can be manufactured for example by injection.
  • the plate 1B intended to position the article to be presented, comprises for this purpose here, where the box is intended for the packaging and the presentation of a single article having a rectangular outline, a light 16B forming receptable for this article ; of course, the light 16B can have any shape suitable for the article or articles to be presented, and the plate 1B can include several lights if the article requires it, or even if the display case is intended to contain several articles.
  • This wafer 1B can be made of any roughly rigid material, depending on the desired appearance, for example cardboard or plastic material injected or not.
  • the frame 1C has a side wall 12C also having a general rectangular configuration, of dimensions slightly greater than those of the side wall 12A of the base 1A so that it can be immobilized around it; this side wall here has four faces, but the end face 121 C corresponding to the location of the fourth face completely released by the opening of the side wall 12A of the base 1A is provided with an opening at its lower part; in addition the side wall 12C of the frame 1 C has, on its two faces adjacent to its end face 121 C, a notch extending the opening of this end face 121 C along these two faces, at their lower part, this notch being limited by a stop edge 122C; of course, it is possible to provide that only the side wall 12A of the base 1A or only the side wall 12C of the frame 1 C has an abutment edge.
  • the faces adjacent to the end face 121 C each have a lug 14C near this end face, these lugs being, as we have seen in the part of the description relating to FIGS. 1 and 2, projecting outwards and located in the extension of one another. So that the plate 1B can be held in the base 1 without being able to escape from the top, the frame 1 C includes a upper edge 17C folded inwards.
  • This frame 1C can also be made of plastic material, for example injected, or any other suitable material such as cardboard.
  • the mounting of the base 1 is particularly simple, since it suffices to place the plate 1B on the base 1A, then to slide the frame 1C around the side wall 12A of the base 1A, its upper edge 17C therefore being at opposite the peripheral rim 13A of the base 1A. It can be provided to fix by any suitable means, for example by gluing, welding or snap-fastening, the frame 1C to the base 1A, or even not fixing these two parts to each other in particular if their adjustment is sufficiently tight; when these two parts are immobilized relative to each other, the plate 1B is kept positioned at the upper part of the base 1A.
  • the cover 2 comprises an interior element 2A and an exterior element 2B intended to cover it, giving it the desired appearance.
  • the inner element 2A is a "bag" produced from a sheet here made of cardboard in the shape of a cross, the central part 21A is intended to constitute the top, and the branches 221A, 222A, 223A, 224A intended to constitute the side wall; so that once the branches folded along the broken line in Figure 4, the cover can closely cover the base, the central part 21A has dimensions slightly larger than the external dimensions of the side wall of the base; so that the side wall of the interior element 2A has a constant height, the four branches 221A, 222A, 223A, 224A have the same length, greater than the height of the side wall of the base depending on the article as the box is intended to receive.
  • Two opposite branches of the cross are provided symmetrically with holes 23A ovalized so that once the branches folded, the cover can pivot as described in the part of the description relating to Figures 1 and 2.
  • the thickness of the sheet is at least approximately equal to the length of the lugs, here of the order of 13/10 of a millimeter, when there is an external element 2B even covering the ovalized holes 23A; otherwise it may be lower.
  • the external element 2B is a "bag" produced from a sheet, generally thinner, here in a paper-plastic complex of a few tenths of a millimeter thick, having the same cross shape as the sheet constituting the inner element 2A, but also comprising folding legs.
  • the external element 2B has a central part 21 B and four branches 221 B, 222B, 223B, 224B; at least two branches 221 B, 223B have lateral tabs 225B (here two lateral tabs per branch) and the branches also include end tabs 226B.
  • the exterior element 2B coated an adhesive on one side, at least in the region of the folds, is bonded to the element 2A on the outside thereof; the inner end tabs 226B 2A provided with ovalized holes 23A have a notch in this region, so that the holes 23A are closed only on the outside face of the cover 2, in order to allow the lugs 14 to pass.
  • the pins 14 are not too close to the end face 121 of the side wall 12 and the peripheral edge 13 of the base 1, so that the ovalized holes 23 of the cover 2 are not too close to the edges of said cover, to avoid tearing of the cover.
  • the invention is not limited to the form and to the embodiment described above and represented, and other forms and other embodiments may be provided; for example, it is possible to provide a cover in a single element, or else, while the above-described shape included a base provided with a peripheral rim allowing the box to be easily wrapped in cellophane automatically, it is possible to provide a peripheral rim much larger or on the contrary non-existent, without departing from the card of the invention.
  • the cover is hinged to the base parallel to a short side, but one can just as easily provide a hinge parallel to a long side or in any other suitable way.

Description

La présente invention concerne les coffrets-présentoirs, notamment les coffrets-présentoirs destinés à l'emballage et à la présentation d'articles de luxe tels que des articles de parfumerie.The present invention relates to display boxes, in particular display boxes for the packaging and presentation of luxury items such as perfumery.

On connaît déjà des boîtes et des coffrets ayant un socle et un couvercle en deux pièces, comportant des organes de pivotement, par exemple des ergots et des trous, permettant de faire pivoter le couvercle par rapport au socle.Boxes and boxes are already known having a base and a two-piece cover, comprising pivoting members, for example lugs and holes, making it possible to pivot the cover relative to the base.

Ainsi, le brevet aux Etats-Unis d'Amérique N° 2491 264 montre une boîte dont le couvercle est enchâssé autour du socle lorsqu'elle est en position fermée, des ergots étant prévus dans le couvercle et des trous oblongs correspondants dans le socle, pour permettre que l'ouverture de la boîte ne soit pas gênée dès le départ par la butée de la face arrière de la paroi latérale du couvercle contre la face correspondante du socle; ainsi, en position fermée, les ergots occupent la partie supérieure des trous oblongs, qui est la plus éloignée de la face arrière de la paroi latérale de la boîte; au fur et à mesure de l'ouverture de la boîte, sous l'effet d'une pression à l'arrière du couvercle ou du poids de ceiui-ci, les ergots descendent dans les trous oblongs, c'est-à-dire que le couvercle descend par rapport au socle, ce qui, compte tenu de l'inclinaison de l'axe longitudinal des trous oblongs, provoque simultanément le recul du couvercle et permet à la face arrière de sa paroi latérale de contourner l'obstacle constitué par celle du socle, c'est-à-dire de basculer sous lui. L'ouverture d'une boîte de ce type nécessite denc de soulever la partie arrière du socle bien avant que le couvercle ait atteint sa position d'ouverture à 90 degrés; lorsque la boîte est posée sur un support horizontal et que son couvercle est ouvert à 90 degrés par rapport à ce support, elle n'est pas elle-même horizontale, à cause de la présence, sous son socle, de la face arrière du couvercle, ce qui peut dans certains cas constituer un inconvénient; il est par ailleurs impossible, la boîte étant ouverte sur un support, de la saisir par son socle ou par son couvercle sans la voir changer brutalement de position d'ouverture (avec toutes les conséquences fâcheuses qui peuvent en résulter), la position d'ouverture stable étant non pas celle dans laquelle la boîte repose sur son support (le couvercle est alors en appui sur celui-ci), mais celle dans laquelle la face arrière du couvercle est en appui contre la base du socle; de plus, il ne faut pas qu'en position fermée cette face arrière recouvre celle du socle jusqu'à la base de celui-ci, afin qu'il ne soit pas nécessaire de solever l'arrière du socle dès le début du mouvement d'ouverture du couvercle; il en résulte, dans cette position fermée, la présence d'un épaulement à l'arrière de la boîte, empêchant un emballage automatique aisé de celle-ci à l'intérieur d'une feuille de matière plastique très mince ou de cellophane; bien entendu, cet épaulement ne peut pas être supprimé en créant une embase ou un rebord à la partie inférieure du socle dans cette région, car cette embase ou ce rebord constituerait une butée empêchant dès le départ l'ouverture du convercle.Thus, patent in the United States of America No. 2491 264 shows a box whose cover is encased around the base when it is in the closed position, lugs being provided in the cover and corresponding oblong holes in the base, to allow that the opening of the box is not hampered from the start by the stop on the rear face of the side wall of the cover against the corresponding face of the base; thus, in the closed position, the pins occupy the upper part of the oblong holes, which is furthest from the rear face of the side wall of the box; as the box opens, under the effect of pressure on the back of the cover or the weight of it, the pins descend into the oblong holes, that is to say that the cover descends relative to the base, which, taking into account the inclination of the longitudinal axis of the oblong holes, simultaneously causes the recoil of the cover and allows the rear face of its side wall to bypass the obstacle constituted by that of the base, that is to say of tipping under it. The opening of a box of this type requires denc to lift the rear part of the base well before the cover has reached its position of opening to 90 degrees; when the box is placed on a horizontal support and its cover is open 90 degrees to this support, it is not itself horizontal, because of the presence, under its base, of the rear face of the cover , which can in some cases be a disadvantage; it is also impossible, the box being open on a support, to grasp it by its base or by its cover without seeing it suddenly change opening position (with all the unfortunate consequences that may result), the position of stable opening being not that in which the box rests on its support (the cover is then supported on it), but that in which the rear face of the cover is supported against the base of the base; moreover, it is not necessary that in the closed position this rear face covers that of the base up to the base thereof, so that it is not necessary to raise the rear of the base from the start of the movement d 'opening the cover; this results in this closed position, the presence of a shoulder at the rear of the box, preventing easy automatic packaging thereof inside a sheet of very thin plastic or cellophane; of course, this shoulder cannot be removed by creating a base or a rim at the bottom of the base in this region, since this base or this rim would constitute a stop preventing the opening of the convercle from the start.

Le brevet français N° 1 142 823 concerne un coffret comportant un socle et un couvercle en deux pièces dont le couvercle est monté pivotant sur le socle non pas grâce à des ergots et des trous oblongs, mais, de manière classique, grâce à une ligne de rainage formant charnière réalisée entre le couvercle et une languette en une seule pièce avec lui et qui est par ailleurs fixée au socle lequel comporte une embase formant un rebord périphérique inférieur pour ce socle sur trois côtés. Ce type de réalisation est extrêmement fragile au niveau de la charnière, la ligne de rainage constituant une zone de moindre résistance sollicitée à chaque manoeuvre d'ouverture et de fermeture de la boîte, même lorsqu'elle est »renforcée« par une feuille d'habillage; les risques de détérioration par déchirure de la charnière sont d'autant plus importants que la languette est collée à la partie supérieure de l'embase, ce qui implique que lorsque le socle, est posé sur une surface sensiblement horizontale, le couvercle étant ouvert à 90 degrés en reposant sur la même surface, la charnière est constamment sollicitée; le fait de saisir alors la boîte par son socle ou par son couvercle provoque également un changement brutal de position d'ouverture, pouvant être aussi préjudiciable à la boîte (au niveau de la charnière) qu'à à son contenu.French Patent No. 1,142,823 relates to a box comprising a base and a two-piece cover, the cover of which is pivotally mounted on the base not by means of lugs and oblong holes, but, conventionally, by means of a line creasing forming hinge formed between the cover and a tongue in one piece with it and which is also fixed to the base which has a base forming a lower peripheral rim for this base on three sides. This type of embodiment is extremely fragile at the hinge, the crease line constituting an area of least resistance requested at each opening and closing operation of the box, even when it is "reinforced" by a sheet of dressing; the risks of deterioration by tearing of the hinge are all the more important that the tongue is glued to the upper part of the base, which implies that when the base is placed on a substantially horizontal surface, the cover being open to 90 degrees by resting on the same surface, the hinge is constantly stressed; grabbing the box by its base or its cover also causes a sudden change in the open position, which can be as damaging to the box (at the hinge) as to its content.

Le brevet aux Etats-Unis d'Amérique N° 2 880 858 montre également un coffret comportant un socle et un couvercle en deux pièces, dont le couvercle est monté pivotant sur le socle grâce à des ergots de forme extérieure circulaire et des trous également circulaires; en vue de faciliter le pivotement du couvercle par rapport au socle, les formes de ces deux parties sont relativement compliquées; en particulier, en position fermée, à l'avant de la boîte, le couvercle pénètre à l'intérieur du socle, tandis qu'à l'arrière de la boîte, le couvercle est toujours extérieur au socle. Là encore, il est impossible d'ouvrir le couvercle à 90 degrés sans soulever l'arrière de la boîte. La nécessaire complexité des formes et notamment la présence de nombreuses faces inclinées empêche d'obtenir aisément un emballage automatisé à l'intérieur d'une feuille de matière plastique très mince ou de cellophane; la création d'une embase à la partie inférieure du socle ne résoudrait aucun des problèms posés, car l'emballage ne serait que peu facilité, et cette embase empêcherait l'ouverture à 90 degrés du couvercle; la seconde forme de réalisation décrite dans ce brevet présente en plus l'inconvénient, lorsqu'elle est posée sur un support en position ouverte, de ne pouvoir être saisie soit par le socle soit par le couvercle sans changement brutal de sa position d'ouverture.Patent in the United States of America No. 2,880,858 also shows a box comprising a base and a two-piece cover, the cover of which is pivotally mounted on the base by means of lugs of circular external shape and also circular holes. ; in order to facilitate the pivoting of the cover relative to the base, the shapes of these two parts are relatively complicated; in particular, in the closed position, at the front of the box, the cover penetrates inside the base, while at the rear of the box, the cover is always outside the base. Again, it is impossible to open the cover 90 degrees without lifting the back of the box. The necessary complexity of the forms and in particular the presence of many inclined faces prevents easily obtaining an automated packaging inside a sheet of very thin plastic or cellophane; the creation of a base at the bottom of the base would not solve any of the problems posed, since the packaging would be only slightly facilitated, and this base would prevent the lid from being opened at 90 degrees; the second embodiment described in this patent also presents the disadvantage, when it is placed on a support in the open position, of being unable to be grasped either by the base or by the cover without sudden change in its open position.

L'invention a pour but de remédier à ces inconvénients et de créer un coffret-présentoir ayant un aspect soigné et une bonne robustesse, tout en restant de fabrication aisée et d'un faible prix de revient, grâce notamment à la possibilité de fabriquer le coffret à l'aide de machines avec un minimum d'interventions manuelles.The invention aims to remedy these drawbacks and create a display box having a neat appearance and good robustness, while remaining easy to manufacture and low cost, thanks in particular to the possibility of manufacturing the box using machines with a minimum of manual intervention.

A cet effet, l'invention concerne un coffret-présentoir du type comportant un socle adapté à recevoir un article à présenter et muni d'une paroi latérale, et un couvercle creux, le socle et le couvercle étant constitués par deux pièces distinctes, le couvercle étant monté pivotant sur une face extrême de la paroi latérale du socle entre une position fermée où il entoure ladite paroi latérale et une position ouverte où il dégage au mois partiellement le socle en laissant apparaître l'article présenté, grâce à des organes de pivotement comprenant d'une part deux ergots saillants solidaires de l'une desdites pièces et d'autre part deux trous ovalisés pour recevoir lesdits ergots et ménagés dans l'autre desdites pièces, coffret-présentoir caractérisé en ce que le socle comporte un rebord périphérique inférieur raccordé à la partie inférieure de sa aproi latérale, sur lequel repose le couvercle en position fermée, et une ouverture dans la région de ladite face extrême de la paroi latérale au moins au voisinage dudit rebord, pour éviter le blocage du couvercle par la paroi latérale du socle avant qu'il ait atteint sa position ouverte. Cette structure permet d'obtenier les avantages recherchés et une manoeuvre aisée du coffret vers la position d'ouverture ou de fermeture.To this end, the invention relates to a display case of the type comprising a base adapted to receive an article to be presented and provided with a side wall, and a hollow cover, the base and the cover being constituted by two separate parts, the cover being pivotally mounted on an end face of the side wall of the base between a closed position where it surrounds said side wall and an open position where it partially releases the base by revealing the article presented, thanks to pivoting members comprising on the one hand two projecting lugs integral with one of said parts and on the other hand two ovalized holes for receiving said lugs and formed in the other of said parts, display case characterized in that the base has a lower peripheral rim connected to the lower part of its lateral apron, on which the cover rests in the closed position, and an opening in the region of said end face of the lateral wall a u at least in the vicinity of said flange, to avoid blocking of the cover by the side wall of the base before it has reached its open position. This structure makes it possible to obtain the desired advantages and an easy operation of the box towards the open or closed position.

Dans une forme de réalisation particulière, les deux ergots saillants sont solidaires du socle, et les deux trous sont ménagés dans le couvercle.In a particular embodiment, the two protruding pins are integral with the base, and the two holes are formed in the cover.

Selon les caractéristiques intéressantes de l'invention, le socle comporte une embase munie d'une paroi latérale ayant une ouverture dans la région d'une face extrême et d'un rebord périphérique inférieur, et un cadre muni d'une paroi latérale ayant deux ergots saillants et également une ouverture et d'un rebord supérieur replié vers l'intérieur, la paroi latérale du cadre entourant la paroi latérale de l'embase, ainsi qu'une plaquette munie d'au moins une lumière formant réceptacle pour l'article à présenter, ladite plaquette étant maintenue à la partie supérieure de l'embase entre des moyens de support tels que des nervures verticales solidaires de la partie intérieure de la paroi latérale de l'embase et le rebord supérieur du cadre, alors que le couvercle comporte un élément intérieur muni de trous présentant une ovalisation et destinés à recevoir les ergots du socle, dont l'épaisseur est au moins approximativement égale à la longueur des ergots du socle, et un élément extérieur recouvrant l'élément de paroi intérieur et qui est plein à l'endoit des trous. Cette conception du socle perment l'emballage d'une grande variéte d'articles à l'aide de seulement quelques types de socle; la conception choisie pour le couvercle permet, elle, une grande diversité de présentation en fonction de la nature et de l'apparence de l'élément de paroi extérieur utilisé.According to the advantageous features of the invention, the base comprises a base provided with a side wall having an opening in the region of an end face and a lower peripheral rim, and a frame provided with a side wall having two protruding lugs and also an opening and an upper rim folded inwards, the side wall of the frame surrounding the side wall of the base, as well as a plate provided with at least one light forming a receptacle for the article to be presented, said plate being held at the upper part of the base between support means such as vertical ribs integral with the inner part of the side wall of the base and the upper edge of the frame, while the cover comprises an inner element provided with holes having an ovalization and intended to receive the lugs of the base, the thickness of which is at least approximately equal to the length of the lugs of the base, and an outer element rec opening the inner wall element and which is full at the end of the holes. This design of the base allows the packaging of a large variety of articles using only a few types of base; the design chosen for the cover allows for a great diversity of presentation depending on the nature and appearance of the external wall element used.

Le coffret-présentoir de l'invention, représenté schématiquement sur les figures 1 et 2, comporte un socle 1 destiné à recevoir un article à présenter et un couvercle creux 2, constitués sous la forme de deux pièces distinctes.The display case of the invention, shown diagrammatically in FIGS. 1 and 2, comprises a base 1 intended to receive an article to be presented and a hollow cover 2, formed in the form of two separate parts.

Le socle 1 comporte lui-même une plaque de base 11 et une paroi latérale 12 placée sur la plaque de base 11, et de dimensions légèrement plus pétites qu'elle, de telle sorte que soit déterminé sur le pourtour de la plaque de base 11, un rebord périphérique 13; la plaque de base est ici de forme rectangulaire, et la forme générale de la paroi latérale est donc également rectangulaire; à proximité de l'une des extrémités de la paroi latérale 12, se trouvent deux ergots 14 saillant ver l'extérieur de la paroi respetivement d'un côté et de l'autre du socle; ces deux ergots 14, ici cylindriques, placés à proximité d'une face extrême 121 de la paroi latérale 12, sont situés dans le prolongement l'un de l'autre pour déterminer un axe autour duquel le couvercle 2 est monté pivotant par rapport au socle 1, entre une position fermée où il repose sur le rebord périphérique 13 en entourant la paroi latérale 12 (c'est-à-dire où il coiffe étroitement le socle 1) et une position ouverte où il laisse apparaître l'article présenté et où pour cela il dégage le socle 1, sauf dans la région de l'axe de pivotement.The base 1 itself comprises a base plate 11 and a side wall 12 placed on the base plate 11, and of dimensions slightly smaller than it is, so that is determined on the periphery of the base plate 11 , a peripheral rim 13; the base plate is here rectangular, and the general shape of the side wall is therefore also rectangular; near one of the ends of the side wall 12, there are two pins 14 projecting towards the outside of the wall respectively on one side and the other of the base; these two pins 14, here cylindrical, placed near an end face 121 of the side wall 12, are located in the extension of one another to determine an axis around which the cover 2 is pivotally mounted relative to the base 1, between a closed position where it rests on the peripheral rim 13 by surrounding the side wall 12 (that is to say where it closely covers the base 1) and an open position where it reveals the article presented and where for this it releases the base 1, except in the region of the pivot axis.

Le couvercle 2 comporte un sommet 21 et une paroi latérale 22 qui, étant destinée en position fermée à coiffer étroitement le socle 1, présente la même forme générale que la paroi latérale 12 dudit socle, avec des dimensions intérieures à peine supérieures aux dimensions extérieures de cette paroi latérale 12; afin de recevoir les ergots saillants de la paroi latérale 12 du socle 1, la paroi latérale 22 du couvercle 2 présente deux trous 23.The cover 2 has a top 21 and a side wall 22 which, being intended in the closed position to tightly cover the base 1, has the same general shape as the side wall 12 of said base, with internal dimensions barely greater than the external dimensions of this side wall 12; in order to receive the projecting lugs of the side wall 12 of the base 1, the side wall 22 of the cover 2 has two holes 23.

Néanmoins, il est nécessaire de prévoir des moyens appropriés supplémentaires pour pouvoir ouvrir le coffret. En particulier, pour que le couvercle 2 ne soit pas gêné par le socle 1 dans son pivotement par rapport à lui par suite du blocage du chant inférieur 221 de la paroi latérale 22 par la plaque de base 11 dans la région de la face extrême 121 à proximité de laquelle se trouvent les ergots 14, un moyen approprié peut consister en ce que ce pivotement ne se réduise pas à une simple rotation, mais soit constitué d'une rotation accompagnée d'une légère translation des deux pièces l'une par rapport à l'autre; de plus, pour que le couvercle 2 ne soit pas gêné par le socle 1 par suite du blocage du chant inférieur de la paroi latérale 22 du couvercle 2 par la paroi latérale 12 du socle 1, un moyen approprié peut consister en ce que la paroi latérale 12 du socle 1 présente une ouverture dans la région de la face extrême 121, au moins au voisinage du rebord périphérique 13. Pratiquement, la translation accompagnant la rotation du couvercle 1 par rapport au socle 2 est obtenue par une ovalisation des trous 23, l'axe de l'ovale étant incliné vers le cas et vers l'avant du coffret-présentoir lorsque celui-ci est en position fermée, le couvercle 2 en appui sur le socle 1; l'ouverture dans la région de la face extrême 121 est située sur toute la longueur de celle-ci, à sa partie inférieure, et se prolonge à la partie postérieure des deux faces de la paroi latérale 12 du socle 1 qui s'y rattachent; afin d'arrêter le mouvement du couvercle 2 à une position ouverte limite, il est possible de prévoir sur chacune des deux faces où se prolonge l'ouverture, un chant de butée 122 pour le chant inférieur 221 de la paroi latérale 22 du couvercle 2; afin que cette position ouverte soit stable même quand le coffret est incliné, on peut également prévoir que la largeur des faces à cet endroit soit supérieure à une valeur minimale appropriée.However, it is necessary to provide additional appropriate means to be able to open the box. In particular, so that the cover 2 is not hampered by the base 1 in its pivoting relative to it due to the blocking of the lower edge 221 of the side wall 22 by the base plate 11 in the region of the end face 121 near which the pins 14 are, an appropriate means may consist in that this pivoting is not reduced to a simple rotation, but consists of a rotation accompanied by a slight translation of the two parts relative to one another. to the other; in addition, so that the cover 2 is not hampered by the base 1 due to the blocking of the lower edge of the side wall 22 of the cover 2 by the side wall 12 of the base 1, an appropriate means may consist in that the wall lateral 12 of the base 1 has an opening in the region of the end face 121, at least in the vicinity of the peripheral rim 13. In practice, the translation accompanying the rotation of the cover 1 relative to the base 2 is obtained by an ovalization of the holes 23, the axis of the oval being inclined towards the case and towards the front of the display case when the latter is in the closed position, the cover 2 resting on the base 1; the opening in the region of the end face 121 is situated over its entire length, at its lower part, and extends to the rear part of the two faces of the side wall 12 of the base 1 which are attached thereto ; in order to stop the movement of the cover 2 at a limit open position, it is possible to provide on each of the two faces where the opening extends, a stop edge 122 for the lower edge 221 of the side wall 22 of the cover 2 ; so that this open position is stable even when the cabinet is tilted, it can also be provided that the width of the faces at this location is greater than an appropriate minimum value.

Le couvercle 2 étant prévu en matière relativement souple, le montage du couvercle 2 sur le socle 1 se fait simplement à force, en écartant sa paroi latérale 22 et en laissant la paroi latérale reprendre sa forme lorsque les ergots 14 sont engagés dans lesdits trous 23; l'ouverture de la boîte s'effectue en faisant effectuer au couvercle 2, en même temps qu'une rotation par rapport au socle 1, une légère translation vers le haut.The cover 2 being provided in a relatively flexible material, the mounting of the cover 2 on the base 1 is done simply by force, by spreading its side wall 22 and letting the side wall resume its shape when the pins 14 are engaged in said holes 23 ; the box is opened by making the cover 2, at the same time as a rotation relative to the base 1, a slight upward translation.

Dans la forme de réalisation représentée sur la figure 3, le socle 1 est constitué par une embase 1A, une plaquette 1B, et un cadre 1C.In the embodiment shown in Figure 3, the base 1 is constituted by a base 1A, a plate 1B, and a frame 1C.

L'embase 1A comporte une plaque de base 11A et une paroi latérale 12A ayant ici une configuration générale rectangulaire, mais ne présentant que trois faces seulement, l'emplacement de la quatrième face étant totalement libéré par l'ouverture destinée à permettre d'ouvrir le coffret; de plus, les deux faces délimitant l'emplacement de la face extrême supprimée comportent chacune une échancrure prolongeant ainsi l'ouverture le long de ces deux faces à leur partie inférieure, cette échancrure étant limitée par un chant de butée 122A. Les dimensions extérieures de la paroi latérale 12A étant plus faibles que celles de la plaque de base 11A, l'embase comporte un rebord périphérique 13A ayant de préférence pour largeur l'épaisseur du couvercle pour qu'il n'y ait pas de partie débordante. La paroi latérale 12A comporte également des nervures verticales 15A solidaires de sa partie intérieure et de la plaque de base 11A; ces nervures verticales, destinées à supporter la plaquette 1B, peuvent s'étendre par exemple perpendiculairement à la face dont elles sont solidaires. L'embase 1A peut être en n'importe quelle matière relativement rigide, mais pour la plupart des applications, les matières plastiques ou le carton sont particulièrement appropriés, notamment le polystyrène, eu égard au faible prix de fabrication qu'elles impliquent; cette pièce peut être fabriquée par exemple par injection.The base 1A comprises a base plate 11A and a side wall 12A having here a generally rectangular configuration, but having only three faces only, the location of the fourth face being completely freed by the opening intended to allow opening the safe; in addition, the two faces delimiting the location of the removed end face each have a notch thus extending the opening along these two faces at their lower part, this notch being limited by a stop song 122A. The external dimensions of the side wall 12A being smaller than those of the base plate 11A, the base has a peripheral rim 13A preferably having the width of the cover thickness so that there is no projecting part . The side wall 12A also comprises vertical ribs 15A secured to its interior part and to the base plate 11A; these vertical ribs, intended to support the plate 1B, may extend for example perpendicular to the face to which they are integral. The base 1A can be of any relatively rigid material, but for most applications, plastics or cardboard are particularly suitable, in particular polystyrene, having regard to the low manufacturing cost which they imply; this part can be manufactured for example by injection.

La plaquette 1B, destinée à positionner l'article à présenter, comporte à cet effet ici, où le coffret est destiné à l'emballage et à la présentation d'un article unique présentant un contour rectangulaire, une lumière 16B formant réceptable pour cet article; bien entendu, la lumière 16B peut avoir n'importe quelle forme adaptée à l'article ou aux articles à présenter, et la plaquette 1B peut comporter plusieurs lumières si l'article le nécessite, ou encore si le coffret-présentoir est destiné à contenir plusieurs articles. Cette plaquette 1B peut être en tout matériau à peu près rigide, en fonction de l'aspect désiré, par exemple en carton ou en matière plastique injectée ou non.The plate 1B, intended to position the article to be presented, comprises for this purpose here, where the box is intended for the packaging and the presentation of a single article having a rectangular outline, a light 16B forming receptable for this article ; of course, the light 16B can have any shape suitable for the article or articles to be presented, and the plate 1B can include several lights if the article requires it, or even if the display case is intended to contain several articles. This wafer 1B can be made of any roughly rigid material, depending on the desired appearance, for example cardboard or plastic material injected or not.

Le cadre 1C comporte une paroi latérale 12C ayant elle aussi une configuration générale rectangulaire, de dimensions légèrement supérieures à celles de la paroi latérale 12A de l'embase 1A afin de pouvoir être immobilisée autour d'elle; cette paroi latérale comporte ici quatre faces, mais la face extrême 121 C correspondant à l'emplacement de la quatrième face totalement libéré par l'ouverture de la paroi latérale 12A de l'embase 1A est munie d'une ouverture à sa partie inférieure; de plus la paroi latérale 12C du cadre 1 C comporte, sur ses deux faces adjacentes à sa face extrême 121 C, une échancrure prolongeant l'ouverture de cette face extrême 121 C le long de ces deux faces, à leur partie inférieure, cette échancrure étant limitée par un chant de butée 122C; bien entendu, il est possible de prévoir que seule la paroi latérale 12A de l'embase 1A ou seule la paroi latérale 12C du cadre 1 C comporte un chant de butée. Les faces adjacentes à la face extrême 121 C comportent chacune un ergot 14C à proximité de cette face extrême, ces ergots étant, comme on l'a vu dans la partie de la description relative aux figures 1 et 2, saillants vers l'extérieur et situés dans le prolongement l'un de l'autre. Afin que la plaquette 1B puisse être maintenue dans le socle 1 sans pouvoir s'échapper par le haut, le cadre 1 C comporte un rebord supérieur 17C replié vers l'intérieur. Ce cadre 1 C peut également être en matière plastique par exemple injectée, ou dans toute autre matière appropriée telle que du carton. Le montage du socle 1 est particulièrement simple, puisqu'il suffit de poser la plaquette 1B sur l'embase 1A, puis de glisser le cadre 1C autour de la paroi latérale 12A de l'embase 1A, son rebord supérieur 17C étant par conséquent à l'opposé du rebord périphérique 13A de l'embase 1A. On peut prévoir de fixer par tout moyen approprié, par exemple par collage, par soudage ou par encliquetage, le cadre 1C à l'embase 1A, ou même ne pas fixer ces deux pièces l'une à l'autre notamment si leur ajustement est suffisamment serré; lorsque ces deux pièces sont immobilisées l'une par rapport à l'autre, la plaquette 1B est maintenue positionnée à la partie supérieure de l'embase 1A.The frame 1C has a side wall 12C also having a general rectangular configuration, of dimensions slightly greater than those of the side wall 12A of the base 1A so that it can be immobilized around it; this side wall here has four faces, but the end face 121 C corresponding to the location of the fourth face completely released by the opening of the side wall 12A of the base 1A is provided with an opening at its lower part; in addition the side wall 12C of the frame 1 C has, on its two faces adjacent to its end face 121 C, a notch extending the opening of this end face 121 C along these two faces, at their lower part, this notch being limited by a stop edge 122C; of course, it is possible to provide that only the side wall 12A of the base 1A or only the side wall 12C of the frame 1 C has an abutment edge. The faces adjacent to the end face 121 C each have a lug 14C near this end face, these lugs being, as we have seen in the part of the description relating to FIGS. 1 and 2, projecting outwards and located in the extension of one another. So that the plate 1B can be held in the base 1 without being able to escape from the top, the frame 1 C includes a upper edge 17C folded inwards. This frame 1C can also be made of plastic material, for example injected, or any other suitable material such as cardboard. The mounting of the base 1 is particularly simple, since it suffices to place the plate 1B on the base 1A, then to slide the frame 1C around the side wall 12A of the base 1A, its upper edge 17C therefore being at opposite the peripheral rim 13A of the base 1A. It can be provided to fix by any suitable means, for example by gluing, welding or snap-fastening, the frame 1C to the base 1A, or even not fixing these two parts to each other in particular if their adjustment is sufficiently tight; when these two parts are immobilized relative to each other, the plate 1B is kept positioned at the upper part of the base 1A.

Dans la forme de réalisation représentée sur la figure 4, le couvercle 2 comporte un élément intérieur 2A et un élément extérieur 2B destiné à le recouvrir en lui conférant l'aspect désiré.In the embodiment shown in FIG. 4, the cover 2 comprises an interior element 2A and an exterior element 2B intended to cover it, giving it the desired appearance.

L'élément intérieur 2A est un »sachet« réalisé à partir d'une feuille ici en carton en forme de croix dont la partie centrale 21A est destinée à constituer le sommet, et les branches 221A, 222A, 223A, 224A destinées à constituer la paroi latérale; afin qu'une fois les branches repliées selon le trait interrompu de la figure 4, le couvercle puisse coiffer étroitement le socle, la partie centrale 21A a des dimensions légèrement plus grandes que les dimensions extérieures de la paroi latérale du socle; afin que la paroi latérale de l'élèment intérieur 2A ait une hauteur constante, les quatre branches 221A, 222A, 223A, 224A ont la même longueur, supérieure à la hauteur de la paroi latérale du socle en fonction de l'article que le coffret est destiné à recevoir. Deux branches opposées de la croix sont munies symétriquement de trous 23A ovalisés de telle sorte qu'une fois les branches repliées, le couvercle puisse pivoter comme décrit dans la partie de la description relative aux figures 1 et 2. L'épaisseur de la feuille est au moins approximativement égale à la longueur des ergots, ici de l'ordre de 13/10 de millimètre, lorsqu'il existe un élément extérieur 2B recouvrant même les trous ovalisés 23A; elle peut être plus faible dans le cas contraire.The inner element 2A is a "bag" produced from a sheet here made of cardboard in the shape of a cross, the central part 21A is intended to constitute the top, and the branches 221A, 222A, 223A, 224A intended to constitute the side wall; so that once the branches folded along the broken line in Figure 4, the cover can closely cover the base, the central part 21A has dimensions slightly larger than the external dimensions of the side wall of the base; so that the side wall of the interior element 2A has a constant height, the four branches 221A, 222A, 223A, 224A have the same length, greater than the height of the side wall of the base depending on the article as the box is intended to receive. Two opposite branches of the cross are provided symmetrically with holes 23A ovalized so that once the branches folded, the cover can pivot as described in the part of the description relating to Figures 1 and 2. The thickness of the sheet is at least approximately equal to the length of the lugs, here of the order of 13/10 of a millimeter, when there is an external element 2B even covering the ovalized holes 23A; otherwise it may be lower.

L'élément extérieur 2B est un »sachet« réalisé à partir d'une feuille, en général plus mince, ici en un complexe papier-matière plastique de quelques dixièmes de millimètre d'épaisseur environ, ayant la même forme en croix que la feuille constituant l'élément intérieur 2A, mais comportant en plus des pattes rabattables. Ainsi, l'élément extérieur 2B a une partie centrale 21 B et quatre branches 221 B, 222B, 223B, 224B; au moins deux branches 221 B, 223B comportent des pattes latérales 225B (ici deux pattes latérales par branche) et les branches comportent également des pattes d'extrémité 226B. De la sorte, après pliage de l'élément intérieur 2A, les quatre branches étant repliés perpendiculairement à la partie centrale de telle manière que leurs bords soient en regard l'un de l'autre deux à deux, l'élément extérieur 2B, enduit d'un adhésif sur une face, au moins dans la région des rabattables, est collé à l'élément 2A à l'extérieur de celui-ci; les pattes d'extrémité 226B intérieur 2A munies de trous 23A ovalisés ont dans cette région une échancrure, de telle manière que les trous 23A ne soient obturés que sur la face extérieure du couvercle 2, afin de permettre le passage des ergots 14.The external element 2B is a "bag" produced from a sheet, generally thinner, here in a paper-plastic complex of a few tenths of a millimeter thick, having the same cross shape as the sheet constituting the inner element 2A, but also comprising folding legs. Thus, the external element 2B has a central part 21 B and four branches 221 B, 222B, 223B, 224B; at least two branches 221 B, 223B have lateral tabs 225B (here two lateral tabs per branch) and the branches also include end tabs 226B. In this way, after folding of the interior element 2A, the four branches being folded perpendicular to the central part so that their edges are opposite one another in pairs, the exterior element 2B, coated an adhesive on one side, at least in the region of the folds, is bonded to the element 2A on the outside thereof; the inner end tabs 226B 2A provided with ovalized holes 23A have a notch in this region, so that the holes 23A are closed only on the outside face of the cover 2, in order to allow the lugs 14 to pass.

D'une manière générale, il est nécessaire que les ergots 14 ne soient pas trop proches de la face extrême 121 de la paroi latérale 12 et du rebord périphérique 13 du socle 1, afin que les trous ovalisés 23 du couvercle 2 ne soient pas trop proches des bords dudit couvercle, pour éviter les déchirures du couvercle.In general, it is necessary that the pins 14 are not too close to the end face 121 of the side wall 12 and the peripheral edge 13 of the base 1, so that the ovalized holes 23 of the cover 2 are not too close to the edges of said cover, to avoid tearing of the cover.

Bien entendu, l'invention n'est pas limitée à la forme et au mode de réalisation ci-dessus décrits et représentés, et on pourra prévoir d'autres formes et d'autres modes de réalisation; par exemple on pourra prévoir un couvercle en un seul élément, ou bien, alors que la forme ci-dessus décrite comportait un socle muni d'un rebord périphérique permettant au coffret d'être aisément enveloppé de cellophane automatiquement, on pourra prévoir un rebord périphérique beaucoup plus grand ou au contraire inexistant, sans pour autant sortir du carde de l'invention. De même, dans l'exemple représenté, le couvercle est articulé au socle parallélement à un petit côté, mais on peut tout aussi bien prévoir une articulation parallèle à un grand côté ou de toute autre façon appropriée.Of course, the invention is not limited to the form and to the embodiment described above and represented, and other forms and other embodiments may be provided; for example, it is possible to provide a cover in a single element, or else, while the above-described shape included a base provided with a peripheral rim allowing the box to be easily wrapped in cellophane automatically, it is possible to provide a peripheral rim much larger or on the contrary non-existent, without departing from the card of the invention. Similarly, in the example shown, the cover is hinged to the base parallel to a short side, but one can just as easily provide a hinge parallel to a long side or in any other suitable way.
