Description

Field of the Invention The present invention relates to a box of

  conditioning a fragile product, consisting of a base and a lid engaged on the base, each formed of a thin plastic veil in one piece, the box lying flat on a flat surface or s stacking on the lid of another identical box. - the base being composed of a bottom receiving the product, bordered by two side walls and two end walls continuing with an edge rising beyond a peripheral bearing surface, - the cover being terminated by a peripheral edge to bear on the peripheral part of the base. State of the art Such boxes formed of a base and a cover fitted on the edge or embedded in the edge of the raised tray forming the base are known types of packaging. These packages are often used for the presentation of products, the base being generally made of a non-transparent thin plastic material while the cover is made of transparent plastic material. In these known boxes or packages, the base sometimes has a cavity whose shape corresponds to that of the product to be received. This cavity has a depth substantially equal to the thickness of the side walls of the base, that is to say, the lift height of the tray to receive the product and hold it in place, the assembly being covered by the transparent cover .

  There are also different transparent packages of fragile products such as pastries. These packages of the above type are presented as parallelepiped boxes. The lid represents the main part and defines a large volume to avoid touching the products even if it is deformed, for example by stacking several boxes. Similarly, if such boxes can be stacked, their stacking is difficult because it is necessary to make fasteners in the base and the lid of each box to receive each time the base of the box placed above. However, the rectangular parallelepiped shape of the lid makes the stack difficult and the cover may collapse locally and at least partially crush the fragile product inside that becomes unsalable. But such boxes are not suitable for fragile products of elongated cylindrical shape like frozen logs.

  OBJECT OF THE INVENTION The present invention aims to develop a box for receiving a fragile product such as an ice log for storage, presentation and transport, facilitating the extraction of the product from the packaging while by making it possible to stack the boxes avoiding their deformation although the boxes are made from a thin sheet of transparent and / or opaque plastic material. This packaging must be rigid and nevertheless very light and require little material for its manufacture which must be simple, despite the complexity of the shape of the box.

  DESCRIPTION AND ADVANTAGES OF THE INVENTION For this purpose, the invention relates to a packaging box of the type defined above, characterized in that A- the lid is in the form of a cylindrical arch bordered by two flat front faces, B the base comprises a planar bearing surface formed by four pads situated at the four corners of the base, a stacking stack-shaped stacking surface near at least one front wall of the base, projecting in the volume of the base and * provided with locking members to engage in complementary locking members of the cover of another identical box, these locking members projecting into the volume of the stacking vault, - a flat bottom raised in relation to the planar bearing surface to the ni-vale of the upper generatrix of the stacking vault, so that the plane of the flat bottom passes over the stacking vault, C- a plateau removable interior installed in the base on the f ond flat and overflowing on the stacking vault.

  The packaging box according to the invention constitutes a mechanically resistant structure due to the shape of the lid and that of the base receiving the lid; this box can receive in superposition several boxes of this type each loaded with a product including a fragile product such as an ice log Without risking crushing or sagging. The cylindrical shape of the box and in particular if the section of the cylindrical arch of the lid is circular and if this section continues with the circular shape of the section of the side walls of the base, the set suggests from the outside the circular cylindrical shape or elliptical of an icy log. Despite the complexity of the shape of the lid and especially that of the base, allowing both the stacking with locking of the box placed above in the box placed below, locking both transverse and longitudinal transmission of forces, the two elements The main parts of the box (the lid and the base) are easily made with simple molds that do not have moving parts. It also enables fast manufacturing, minimizing the need for scrapping. In addition, the complexity of the shape of the base, necessary for the holding of the box and especially the possibility of stacking and blocking of several boxes on top of each other, does not translate into a complex aspect of form since all these elements are in the bottom of the base. Only the curvature of the support vault appears on the front faces of the box. But this shape gives more lightness to the appearance of the box that seems to rest simply on two longitudinal lines corresponding to the lower longitudinal edges of the base. The two parts of the box are also stackable sim-20 crying which constitutes an important advantage for the storage of empty boxes. Finally, in the base, the cooperation of the shapes of the bearing surfaces, of the stacking surfaces and of the raised flat bottom, descending by its edges to join the lateral walls and the bearing surfaces, results in an extremely rigid assembly despite the thinness of the film forming the base. In the case of the lid, the mechanical strength is ensured by the cylindrical shape of the vault and its meeting at the two flat front faces and in particular, advantageously, the cylindrical arch 30 of the circular section lid is joined to the front faces by a zone rounded. The zone rounded at one end or at both ends of the cylindrical arch constitutes a stiffening element practically comparable to a hoop, all the more interesting since the support of one box on the other is mainly done near both ends. of the lid.

  According to another advantageous characteristic, the box is symmetrical both with respect to its longitudinal median plane and its transverse median plane. According to another particularly advantageous feature, the locking members of the base and the cover are formed by translationally compatible deformations (to the nearest wall thickness) of the base support vault and the homologous vault portion of the base. cover, - the locking members of the base being two transverse re-entrant corners, symmetrical with respect to the longitudinal median plane, in the form of straight curvilinear triangles delimited by a low side in the extension of the flat bearing surface of the base and a second side perpendicular to the previous one, the third open side being the outline of the stacking vault, these two members forming two stacking ribs protruding into the volume of the stacking vault leaving between their second side, an interval for overlapping from the outside, the homologous gap formed between the locking members of the cover, in the form of reentrant corners, ident Those of the base but constituting accessible housings from outside the cover. The locking members of both the base and the cover which are in fact homologous deformations made in the vault-like surface of the cover and its return to the base, are forms which interlock perfectly because one is copying the other, the only difference being related to a slight shift produced by the thickness of the cover material and that of the base. According to another advantageous characteristic, the end pads are joined by longitudinal bearing lines. These lines border the longitudinal sides of the base and form support lines 30 of the base on a flat surface in addition to the end pads. These support lines also stiffen the base of a box when it is stacked on another box and rests on this box from below only by his or her support vaults. According to a particularly advantageous feature, the flat bottom has two longitudinal edges down to the longitudinal side edges to join the longitudinal bearing lines and the end pads.

  These longitudinal edges of the flat bottom combined with the longitudinal sides form, on each side of the flat bottom, a V-beam structure stiffening the base and the combination of the base and the cover. This rigidity is further improved if pairs connect the longitudinal-dinar walls and the sides of the bottom to go up and form consoles to support the edge of the removable inner tray. These couples can also go above the plane of the peripheral edge of the base to form an inner stop holding the edge of the cover on the edge of the base within the rising edge of the base. According to another advantageous characteristic, the base comprises at least one end support passing through the stacking vault and up behind the front wall, above the flat bottom to the ni-veau consoles.

  According to another feature, the flat bottom is provided with at least one orifice, in particular closed by a breakable lid, to allow the passage of a finger used to lift the plate carrying the product in the box. The breakable lid is attached to the edge of the orifice only by an easy link to break.

  The bottom may also include several orifices to pass two or three fingers of the hand through the bottom and lift the inner tray carrying the product so as to facilitate its extraction from the base, especially since the tray is retained by the beakers. 'engages. Passing under the tray, it avoids having to introduce a sharp object between the edge of the tray and the base to take at least one place, the tray and be able to lift. This is all the more important that the product is fragile and that lifting the inner tray by one end or at a point, there is a risk of damaging the product placed in the box. Finally, the fact that the tray can be removed avoids having to extract the product with a cake shovel or other, down into the base which would be a delicate operation that could damage the appearance of the product. To retain the flat bottom, it is advantageous to make consoles or at least some of the brackets in the side walls at the height of the pairs and to overcome each of a snap-nose, located at a distance from their surface bearing substantially corresponding to the thickness of the rim of the plate so that this flange descends on the snap-fasteners by elastic deformation to snap into the gap between each spout and the support surface of the console so as to to hold the tray in this position. The couples and consoles and the flat bottom, raised, prevent the pedestals stacked into each other are glued into each other, these means to maintain an interval between the stacked bases facilitating their grip and removal. For the covers, insofar as these have no projecting elements and capable of ensuring their spacing in the stacked state, it is advantageous to provide on the front faces, slightly raised portions serving Stacking stops.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION The invention relates to a box for packaging a fragile product, generally composed of a lid in the form of a cylindrical arch bordered by two front faces, in particular planar faces, and a receiving base. lid. This base has a flat bearing surface constituting its lower surface by which it rests on a flat surface such as a tray or a table. This bearing surface is formed by pads located at the four corners of the base. The underside of the pedestal has a stacking vault stacking surface near one or both of the pedestal end walls. The stacking vault protrudes into the volume of the base, that is to say towards the interior of the base. It comprises locking members intended to cooperate with locking members complementary or homologous to the lid of another box on which this box or this base will be placed. These locking members of the base project in the volume of the stacking vault.

  Finally, the base has a flat bottom raised relative to its flat bearing surface. This bottom is raised to the level of the upper generatrix of the stacking vault so that the bottom plane is located at the top of the stacking vault or that this geometric plane passes just above this vault stacking.

  Finally, the box receives in the base a removable inner plate resting on the flat bottom and against the sides. The tray also decouins on the stacking vault since it does not exceed the level of the flat bottom so as to occupy the largest available space inside the base.

  This packaging box described in a general manner will be explained below using two embodiments. A first embodiment of a box 100 according to the invention will be described with reference to FIGS. 1 to 12. 5 This box 100 consists of a lower part or base 1 forming the receptacle, covered by a cover 3 applied on the base. Each of these two parts 1, 3 of the box is formed by molding a thin plastic film in one piece. The overall shape of the conditioning box is symmetrical with respect to the longitudinal median plane PML as well as a median transverse plane PMT. These plans are not shown in all the drawings but serve as a reference to the explanations and appear only in Figure 1. The box 100 is intended to be placed on a flat surface, alone, or to be stacked on another box of the same type or to be stackable such a box or a succession of boxes. The stacking and holding of the boxes stacked one on the other 15 are provided by means of connection, hooking and support, made of the base 1 and the cover 3 in positions and with homologous shapes to ensure this. liaison and the transmission of efforts. These forms are shapes obtained by translation of a part of the base towards the corresponding part of the cover and reciprocally as it appears when two boxes are stacked one on the other. The box generally has a cylindrical shape of circular section, the underside of which is truncated to constitute both the bearing surface allowing the box to rest on a flat surface and the curved bearing surface of the lid of a box. other box. This cylindrical shape is delimited by the sides 12, 32 correspond globally to the cylindrical surface of the box and the two end walls 11, 31 of the base 1 and the lid 3. The isometric view of Figure 1, the side view of Figure 2 and the top view of Figure 3 show more particularly the hooking and connecting means 33 of the lid, the means homologous to the base 1 not appearing in these figures. Figure 1 also shows the breakable tabs 14 provided at the corners of the base 1 to constitute tamper evidence of the box. The cover 3, engaged in the edge of the base 1, is hooked to the snap stops provided at the breakable tongues 14 so that once in place, it can not be removed after tearing tabs 14 .

  Figures 4 and 5 are two isometric views showing in more detail, the base 1 seen from above and seen from below. The base 1 is a rectangular receptacle, constituted by a lower surface of complex shape, receiving a tray (Figure 6) and bordered by the two longitudinal sides 12 of curved section and the two end sides 11, planes, joining the curved sides by the rounded edges 15 terminated by the breakable tongues 14. The longitudinal sides 12 and the end sides 11 for-ment a peripheral bearing surface 16 lined externally by a rising edge 24, in which is placed the edge of the lid 3 The underside of the base 1 is a flat bearing surface composed of four end pads 17-1 located at the four corners of the base. These end pads 17-1 are connected by two narrow longitudinal surfaces or support lines 17-2 along the longitudinal sides 12. At each end of the base, the lower surface is in the form of a stacking arch 18 constituted by a curved cylindrical surface, homologous to the cylindrical shape of the roof 32 of the cover 3. This cylindrical surface, which partially joins the end pads 17-1, comprises two paired stacking members 19, in the form of triangular ribs mixtiligne ve projecting into the volume of the stacking vault 18 and arriving for example up to the level of the skids 17-1. These hollow triangular stacking members 19 are separated at the longitudinal median plane of the base by a cavity 20 opening into the hollow of the stacking vault 18.

  These stacking members 19 are in fact two reentrant, transverse corners, symmetrical with respect to the longitudinal median plane. They have the shape of straight curvilinear triangles delimited by a low side 19-1 in the extension of the flat bearing surface defined by the pads 17-1 of the base and a second side 19-2 perpendicular to the preceding; the third side is actually an open side formed by the outline of the stacking vault. The interval between the two second sides 19-2 defines the width of the cavity 20. The majority of the lower surface of the base 1 is occupied by a flat bottom 21 between the stacking arches 18 and the longitudinal walls 12 of the basement. This flat bottom 21 has the shape of a box turned back down by its edge 21-1 to the level of the end pads 17-1 and longitudinal bearing lines 17-2. The flat bottom 21 in the form of box thus constitutes a means of stiffening the lower surface of the base 1. The box is turned up to the longitudinal walls 12 of the base 1 by pairs 22 rising above the flat bottom 21, the Along the curved walls 12 to form consoles. At each end of the base 1, the stacking vault 18 is also traversed by an end console 23 set back from the end wall 11 of the base and communicating with the cavity 20. Each end console 23 is formed in the form of a transverse bar, 10 hollow opening under the stacking vault 18. In this example, the cavity 20 rises to the height of the end console 23 to pro-skirt this bearing surface. At the four corners of its flange 24, the base carries the breakable tongues 14 in which the lid snaps to be retained almost permanently, its removal requiring tearing of the breakable tabs. It should be noted that the flat bottom 21 of the base is located substantially at the height of the top of the stacking arches 18 while the consoles formed by the pairs 22 go up above this surface to the level provided for the support of the edge of the inner plate. It is the same for the end consoles 23 in the form of bars and the extension of the cavity 20 which also reach this level of height of the consoles, thus exceeding the level of the flat bottom 21. According to Figure 6, the base 1 receives an inner tray 5 25 constituted by a flat bottom 51 bordered by rising sides 52 and terminated by a peripheral rim 53 intended to come between the brackets and above them so as to be wedged in the base 1. The plateau 5 is obtained by thermoforming. The lid 3 of the box (FIG. 7) consists of an elongate cylindrical vault piece 32 bordered by two end faces 31 joined to the vault by a rounded zone 34. At the base of the ends of the two rounded zones 34 , there are snap pins 35 catching in the breakable tabs 14 of the base. The clipping is done by elastic deformation but it is irreversible. Near the rounded zone 34, the roof 32 has, at the top, two transverse stacking housings 33 of complementary shape to that of the stacking ribs 19. These stacking housings generally have a triangular vertical section with an bottom surface 33-1 horizontal, bordered on the side of the longitudinal plane of symmetry by a vertical wall 33-2 to join the cylindrical surface of the roof 32 (Figure 8). The two stacking housings 33 are separated by an intermediate portion 34, which has the shape of the wall 32 and is housed in the stacking cavity 20 between the stacking members 19 of the base 1 (Figure 11). The shape of the part of the roof 32 of the lid 3 and the shape of the support vault 18 of the base and that of the locking means are complementary or more exactly, obtained by translation. These forms differ only in the thickness of the wall since the raised portions of the base are in the recessed portions of the lid of the box on which the base is stacked and reciprocally, the recessed portions of the base such as the surface of the base. support, come to bear against the convex portion of the cover placed below, that is to say the corresponding zone of the cylindrical wall 32 of the lid 3.

  The locking members provide in addition to the assembly of the bearing surfaces and the arch, a locking in the transverse direction and in the longitudinal direction of the base relative to the lid of the box on which it is based. These forms appear more clearly in FIG. 8, which is a sectional view of the box in line with the members 19 and the stacking housings 33. Starting from the bottom of the base 1 towards the cover 3, it shows more particularly first the end pads 17-1 on either side of the stacking vault 18; the stacking members 19 have a horizontal bottom surface 19-1 and a vertical wall 19-2 on either side of the cavity 20. In this embodiment, the cavity 20 is relatively narrow, the members 19 being brought close together so that the upward extension of the cavity 20 that joins the end console 23 (not shown in this sectional view) has substantially the same section as this one.

  This FIG. 8 also shows the longitudinal walls 12 with the peripheral support 16 and the rising edge 24 receiving the lower edge of the cover 3. In order to prevent the cover 3 from escaping inwardly from the longitudinal walls 12, those These are formed of lugs 12-1 rising above the peripheral support surface 16. FIG. 9 shows, by an end cut, the lower part of the box with the base 1 and the lower edge of the cover 3 engaged in the base 1 and the plate 5 resting against the flat bottom 21 of the base against and on the brackets 22. The plate carries the product P. Figure 10 shows the detail of the connection between the the edge of the cover 3 which comes on the peripheral support surface 16 being held between the upright flange 24 and the lugs 12-1. Figures 11 and 12 show in sectional view the stack of two boxes 100 and in standing view, the various means necessary for this stacking and blocking the package from above to that below. A second embodiment of a box according to the invention constituting a variant of the first embodiment will be described hereinafter with reference to FIGS. 13 to 19. In this description and in the corresponding figures, the same elements as those of the first embodiment will carry the same references supplemented by the suffix A. The entire detailed description will not be repeated.

  According to Figure 13, the alternative embodiment of the package 100A is a box formed of a base 1A and a cover 3A having substantially the same general shape as that of the first embodiment. However, the base 1A has on its long sides 12A, two latching members for the plate and the cover 3A has on its end faces 31A, stacking stops 36A empty Such stub stops are not necessary for the base lA which has enough relief elements inside to prevent two stacked pedestals marry closely. These shape characteristics do not exist on the lid, it thus requires the realization of these abutments 36A. The isometric view of one end of the box 100A shown in Figure 14 shows the two stacking abutments 36A slightly protruding from the front face 12A constituting substantially vertical surfaces relative to the bearing plane of the box then that the front face 12A is slightly inclined in the re-entrant direction. This figure also shows the arrangement and shape of the stacking housings 33A, shorter and whose vertical branch 33-2A is further away from the longitudinal median plane of symmetry than in the first embodiment.

  In fact, the shape of the members or ribs 19A or recesses 33A depends solely on the geometry of the support vault 18 (and of the vault 32 which is its counterpart) with respect to the plane of the skids. support 17-1A. In this intersection of two geometric surfaces, the outer end of the members 19A or the housings 33A is always the same but the length of the members 19A and, consequently, that of the housings 33A may vary, the corresponding width of the cavity 20A varying from complementary way since the sum of the lengths of the two pins and that of the cavity is constant. As the housings 33A receive snap lugs described later and which are in a homologous position but in the base 1A, these ribs are shorter. This figure also shows the size of the breakable legs 14A, offering a good grip for pulling.

  The characteristics of the base will appear in FIGS. 15 and 16. The base plate 1A has end pads 17-1A connected by two narrow longitudinal bearing surfaces 17-2A. At both ends of the base 1A, the two stacking arches 18A are constituted by a curved cylindrical surface of shape corresponding to that of the roof 32A of the cover 3A, the stacking members 19A, relatively short, leaving between them a large surface of the stacking vault 18A. These stacking members 19A are triangular hollow ribs, the horizontal side 19-1A is in the extension of the end pads 17-1A and the other side 19-2A is a vertical side.

  The end consoles 23A have a shape similar to those of the first embodiment and end with an extension 23-1A coming above the vault 18A. The longitudinal sides 12A comprise, in addition to brackets 22A formed by pairs 22A and extending upwardly by lugs 12-1A, also brackets 25A provided with a snap-fitting nose 26A instead of the pairs 22A. The bottom 21A is a flat bottom similar to the previous one but it comprises detachable parts 21-3A or holes with detachable lids for the passage of fingers so as to lift from below, the tray placed in this base lA and y access more simply to clear the product packaged in this box. The bottom 21A may be covered externally by a label or remain as shown in Figure 15. Figure 17A shows, in the inverted position, one end of the base lA showing the stacking lugs 19A, the vault 18A and the cavity formed by the end console 23A and the end pads 17-1A.

  17B and 17C show more particularly the shape of the consoles 25A provided with their snap-fitting nose 26A formed in the longitudinal wall 12A of the base. The bracket 25A, like the spout 26A, are hollow portions opening outwardly from the longitudinal side 12A s of the base. Figure 17C shows the flange 53A of the inner plate 5A supported on the top of the bracket 25A and retained by the snap-fitting nose 25A. Figure 18 shows the base 1A in which the inner tray 5A is placed. Figure 19 shows the stacking of two boxes 100A. 15 35
