- FIG. 1 to 8 there is shown a first package 10 and a second package 40 both made according to a first embodiment of the invention. As will be detailed later, the first and second packages (10, 40) are intended to be assembled to form a meal tray 2, shown in Figure 6, in which it is possible to eat.
- the first and second packages (10, 40) respectively comprise a lid (11; 41) and a tray (15; 45).
- the covers (11, 41) are both tear-off lids, made, for example, by a metal foil or a plastic film, which have an inner surface which is tearingly attached to the container (15; 45) in a manner well known in the field of packaging, and an upper surface on which indications (13, 43) schematically represented for identifying the contents in the package.
- each of the trays (15, 45) is flat, but it could include ribs or depressions so as to strengthen its rigidity. In all cases, the bottom defines a mean plane on which the trays., Can lie flat in a stable manner.
- the annular wall (17; 47) is connected to the periphery of the bottom (16; 46) by a curved portion and extends generally vertically to the upper " periphery " (18; 48) of the container (15; 45). .
- the annular wall (17; 47) which forms the sides of the tray has a generally D-shaped cross section with a first face generally facing the connecting side (19; 49) which is more or less complex depending on the embodiments. and a second substantially arcuate face which is generally oriented on a so-called "outside" side.
- the annular side wall (17, 47) extends up to the upper periphery (18; 1 48) which defines the annular edge of the opening of the tray.
- the periphery 18 of the first tray 15 has substantially the shape of a D, while the periphery 48 of the second tray 45 has an elongate oval shape. But, of course, the opening of each tray could have a substantially different shape, especially depending on the cross section of the side wall.
- the bottom (16; 46) and the side wall (17; 47) define a receptacle (14; 44) for receiving a food product.
- the receptacle (14; 44) has a height measured between the bottom (16; 46) and the upper periphery (18; 48) which is relatively small compared to the dimensions of the periphery measured in its upper part. great length, and generally a height less than one third of the length. Note also that the area of the opening is large, of the order of the maximum cross section of the side wall (17; 47), so that it is easy to access the contents of the tray and that the you can eat directly in it with a canopy.
- the assembly flange (21; 51) of each tray (15; 45) extends from a portion of the periphery (18; 48) to a free end (22; 52) located outside the container. .
- the assembly flange (21; 51) is in a plane parallel to the mean plane of the bottom and defines with the periphery (18; 48) the average plane of the upper face of the package.
- the assembly flange (21; 51) is continuous along the entire length of the assembly side (19; 49) and integral the corresponding portion of the periphery (18; 48). However, it is conceivable that the assembly flange extends only over a portion of the assembly side or that it comprises a plurality of discrete portions along the assembly side.
- the trays (15, 45) also each comprise a flange (23; 53) extending along their outer side, similarly to the assembly flange (21; 51) forming with it a collar, annular continuous which rigidifies the package and on which the tear-off lid (11; 41) is fixed.
- the first tray 15 has a first fulcrum 25 and a second fulcrum 26 formed by a reduced area of the free end 22 of the assembly flange 21, extending over the thickness of the rim assembly, and indicated by a pellet in Figure 1 for the sake of clarity.
- the first tray 15 has a third fulcrum 27, and a fourth fulcrum 28 respectively formed by the • vertex of a first protruding boss 29 and a second protruding boss 30 which are both arranged in the side wall 17 of the tray 15, facing the assembly side 19.
- the bosses (29, 30) have a geometric shape adapted for the third and fourth bearing points (27, 28) are located on the side 19 and closer to the mean plane of the bottom 16 that the plane of the upper face of the tray 15.
- the set of support points (25, 26, 27, 28) arranged appropriately relative to the center of gravity of the filled package, forms a base along the assembly side 19, that is to say on one side of the package which defines a straight line L average length relatively large compared to the other dimensions of the packaging.
- the package 10 may be arranged vertically vertically, as shown in Figure 2, on a horizontal plane Pl whose trace is also visible in Figure 7.
- the bearing points (25, 26, 27, 28) must define a polygon, here a rectangle, above which is located the center of gravity of the package filled, that is to say taking into account the weight of the tray, the lid and the food contained in the receptacle 14, and taking into account that the food can possibly move in the receptacle when the tray is moved from a horizontal position for which it rests on its bottom 16, to a vertical position for which it rests on. the fulcrums (25, 26, 27, 28).
- the package 10 can be arranged vertically in a row composed of a plurality of identical packages, occupying a radius of for sale a place much less important than if it was arranged flat. N r It is not necessary to form a vertical stack that can be tipped over, or to provide an intermediate support between the radius and packaging, such as for example a honeycomb plate, in spite of the relatively complicated geometry of the tray.
- the package When the package is disposed on the wafer, it has a front face, that is to say arranged facing consumers as shown in Figure 2, which corresponds to the larger dimension of the package 10 and which is essentially formed by the cover 11.
- the cover 11 has indications 13 which can be sufficiently large and numerous to provide consumers with clear and complete information on the food content of packaging, so it is not absolutely necessary to provide an overpack to fill this role of information.
- the complete package 10 can be sold in the configuration shown in Figure 2, that is to say without overpack.
- an overwrap without departing from the scope of the present invention, such as a stretched plastic film through which the support points (25, 26, 27, 28) of the base retain their function, or a sleeve in cardboard sheet.
- the amount of material used for the overpack can be reduced because the sheet is not necessarily rigid and it is not necessary to provide internal locking means, because the base the package can rest against one side of this overpack.
- the second package 40 also includes an analog base to the first package, which allows to arrange it vertically on the assembly side 49, as can be " ⁇ the ⁇ see Figure" 4.
- the base of the second package has only three points of support. Indeed, in addition to the first and second bearing points (55, 56) formed on the free end 52 of the assembly flange 51, the tray 45 has only one additional support point, the third point of support 57 formed at the top of a projecting boss 59 of the annular wall 47.
- the boss 59 is made analogously to the bosses 29 and 30 of the first tray 10, but located in the center of the face of the annular wall 47 which is next to the assembly side 49.
- the three support points (55, 56, 57, 58) of the base of the second tray 40 are arranged relative to each other so as to define a triangle above which is located the center of gravity of the packing filled when this base is based on a horizontal plane P2.
- the trace of the plane P2 on which can rest the second tray is visible in Figure 8.
- the free end (22; 52) of the assembly flanges (21, 51) has corrugations with respect to the middle line L of the assembly side (19; 49) which is parallel to the straight line passing through the two means hooking (24; 54) of this rim.
- These corrugations comprise in particular two corrugations (32; 62) which project relative to the average line L near the ends of the assembly side (19; 49), and at the top of which are formed the first and second support points. (25, 26; 55, 56).
- This arrangement spaced apart from the first and second support points makes it possible to increase the stability of the package when it rests on the wafer.
- the second tray also has a projecting corrugation in the middle part of the assembly side, but its height is less than the corrugations 62, which avoids a wobbly base.
- the hooking means (24, 54) are arranged on the edge of one assembly. (21; 51) at the projecting undulations (32; 62) where the rim has a maximum width.
- Each hooking means (24; 54) of the two trays (15, 45) is a bowl-shaped recess formed by the thickness of the assembly flange, which has an opening opening into the upper face and a projecting portion.
- the inner diameter of the assembly means 24 of the first tray 15 is adapted to the outer diameter of the attachment means 54 of the second tray 45 , so that the protruding portion of the hooking means 54 can be nested in the recess of the attachment means 24 by exerting pressure.
- the cooperation of the attachment means (24, 54) preferably exerts between them a friction adapted so that they remain assembled under normal conditions of use, and in particular when grasping with one hand the formed plate 2 by the first and second trays (15, 45) assembled.
- the hollow-shaped hooking means (24, 54) of the embodiment shown are assembled in a reversible manner, but it is possible to provide hooking means of any known type, and in particular hooking means that can be assembled. irreversibly by snapping.
- protruding bosses (29, 32) of the first tray 15 which extend beyond the plumb of the hooking means 24, as can be seen in FIG. 7, form polarizing means which prohibit the assembly of the first tray 15 with an identical tray. Indeed, these bosses would interfere with the bosses of the identical tray if one sought to bring in correspondence of the attachment means 24 with those of the other tray.
- the boss protruding • 59 of the second tray 45 forms a keying means which prohibits the second tray of the assembly with an identical tray.
- the median corrugation 63 of the second tray 45 forms an additional deterrence means. Indeed, the median corrugation 53 would interfere with the side wall of an identical tray if one sought to bring in correspondence of the attachment means 54 with those of the other tray.
- the portion of the upper rim (18; 48) from which the assembly flange (21; 51) extends comprises different portions which form an angle ⁇ 1 with the center line L of the assembly side. As can be seen in Figures 1 and 3, these portions belong to a curved portion of the upper periphery (18; 48), which is medially located between the ends of the connecting side (19; 49). This configuration of the periphery greatly increases the flexural rigidity of the assembly flange.
- each tray (15; 45) of the first and second packages (10, 40) is made of plastic, formed in one piece comprising the tray, its assembly flange, the hooking means and the base defined by the dots. 'support.
- the tray is thus manufactured in large numbers at a lower cost, but it is conceivable to make points of support of the base, and in particular the third point of support, by a patch on the tray.
- the first and second packages (10, 40) form a packaging system which makes it possible to produce a meal tray, and preferably a plate 2, by assembling the first and second packages along their assembly side (19, 49). ) respectively.
- a third package can be assembled with one and / or the other of the first and second packages (.10, 40), or that the container of the container of a package is compartmentalized, for example to contain a salad and a sauce separately, or that one of the packaging of the system has a shape that does not require to achieve for it a base for placing it on its edge.
- each of the packages (10; 40) have complementary arcuate shapes so that the assembled packages 2 are reminiscent of the shape of a traditional plate, that is, that is to say that the assembly has a substantially circular or oval shape and of dimension of the same order of magnitude as that of an individual plate.
- the assembly side (19; 49) corresponds to a diameter or a rope of the plate, that is to say a rectilinear portion of significant length. -.
- first packages 10 are placed at his disposal, each containing a dish selected from among a first series of dishes which may comprise, for example, accompaniments such as rice, lentils, pasta, etc.
- Second packs 40 containing other dishes selected from among a second series are also provided, which include, for example, main dishes such as chicken, chicken, and the like. fish, veal, etc.
- the exact composition of the dishes of the first series is constituted as a function of each of the dishes of the second series, so that the dish or the meal composed by the contents of one of the first packages and the contents one of the second packs form a balanced meal, that is to say whose intake of protein, fat, carbohydrates and other elements such as mineral salts is in dietary proportions.
- these proportions and the total amount of the intake of the meal can be adapted according to the person to whom this meal is intended. Due to the presence of coding means on the trays (15, 45) of each of the first and second packagings (10, 40), the fact of consuming a complete meal tray 2 of the packaging system, guarantees the consumer a contribution balanced nutrition.
- the assembly flanges (21, 51) are shaped relative to one another so as to form a continuous surface between the first and second packages (10, 40) when they are assembled.
- the free end (22, 52) of the assembly flanges has the profile of a curved line which makes it possible to have an overlap of the assembly edges (21, 51) in certain zones, and in particular at the level of the attachment means, or to have an adjacency of the free ends (22, 52) in other areas, and in particular in the middle part of the assembly side.
- the first and second trays (15, 45) are formed by heat-blowing, that is to say by hot blow molding a preform in a mold.
- This manufacturing method makes it possible to achieve a wide variety of shapes for the receptacle (14; 44), and in particular concave shapes.
- FIGS. 9 to 13 show a first package 10 and a second package 40 made according to a second embodiment of the invention, and FIGS. 14 and 15 show a variant of the first package 10 made according to this second embodiment. .
- the first and second trays (15, 45) each have a bottom (16; 46), an annular side wall (17; 47), an upper periphery (18; 48), an assembly flange (21; 51) extending along an assembly side ( 19; 49), which is provided with attachment means (24; 54). Unless otherwise indicated, these elements are identical to those of the first embodiment.
- the trays (15, 45) of the first and. second packs are closed by a tear-off operculum, not shown for this second mode,. for marketing.
- the first and second trays (15, 45) define a receptacle (14; 44) flared towards the upper opening, i.e. without concave boss in the side wall.
- the assembly flange (21; 51) of each of the trays comprises at least one support element (34, 35; 64) which extend from the respective assembly flange ( 21; .51) towards the middle plane of the bottom (16, 47).
- the assembly flange 21 comprises a first support member in the form of a flange 34 which extends from the portion of the free end 22 of the assembly flange forming the projecting undulation 32, and has a curved wall about its longitudinal axis perpendicular to the assembly flange, which increases its rigidity.
- the second projecting corrugation 32 includes a second wing 35 similar to the first wing 34.
- the wings (34, 35) respectively provide a third fulcrum 27 and a fourth fulcrum 28 which compose with the first and second fulcrums (25, 26) a base on which the tray can rest, the upper face and the bottom 16 being substantially vertical, in a so-called configuration on the edge. According to the quality of manufacture and the flatness of the. With the support surface, one can even obtain two parallel bearing lines and each passing through the points (25, 27) and (26, 28).
- the wings (34, 35) are perpendicular to the joining flange 21, which allows a perfectly vertical position when the bearing points (.
- 25,26,27,28 are based on a plane P disposed horizontally, but it ' It is possible to provide an angle of inclination of a few degrees while maintaining a good stability.- • It will be noted that the rigidity of the assembly flange (21), reinforced by the curved portion of the
- the wings 34 and 35 are arranged at the ends of the assembly side 19 and extend to near the 16.
- the lower end of the support elements formed by the wings (34, 35) is included in the mean plane of the bottom 16 of the tray, so as to rest on a table. same time as the bottom 16.
- the support elements (34, 35) form additional support points in line with the assembly flange 21 when the tray 15 is disposed flat. This arrangement makes it possible to avoid tilting of the tray 15 previously placed on a table, when the user exerts pressure on the assembly flange 21 thereof with the assembly flange 51 of the second tray 45 for mutually support the means latching (24, 54).
- the wings (34,35) provide. additional supports to the tray (15) arranged flat, which solve the problem of stability when assembled • with the second tray (45).
- the second tray 45 also comprises a support member 64 formed by a single wing which is similar to the wings (34, 35) of the first tray 15, but which extends from a median portion 63 of the free end 52 of the flange. assembly of the second tray 45.
- the wing 64 provides a third fulcrum 57 located near the middle plane of the bottom 46, which forms a triangular base with the first and second bearing points (55, 56).
- the wing 64 also has a curved profile according to the curvature of the medial portion of the free end 52, which increases its rigidity and prohibits almost any possibility of flexion with respect to the assembly flange 52.
- the bearing points (25, 26, 27, 28, 55, 56, 57) are arranged with respect to the center of gravity of their respective tray (15, 45) so that this center of gravity is located above the polygon formed by the points of support when the tray rests on a horizontal plane whose trace (P1, P2) is shown respectively in Figures 12 and 13.
- the support member 36 extends from the free end of the assembly flange 21 to the middle plane of the bottom 16. This support member is a wing continuous 36 extending over the entire length of the assembly side 19. This improves the support perpendicular to the assembly flange 21 when the tray is disposed flat, but also allows to significantly increase the rigidity assembly flange 21 due to the curved profile of this flange 36.
- the continuous wing 36 comes to marry the wing 64 of the second tray 45 and therefore limits the possibilities of bringing the annular walls (17, 47) closer together.
- the wing 36 has a hook 37 arranged at the lower end and on the outer face thereof. The hook
- the wings (34, 35; 36; 64) prohibit for each of the trays (15; 45) an assembly with an identical tray, so that these wings have an additional function of foolproofing.
- the trays (15; ) of the second embodiment are manufactured in one piece by pressure injection of plastic into a mold.
- Figures 16 to 21 there is shown a third embodiment of the first tray 15 and the second tray 45. These trays have many.s similarities with the trays of the second embodiment and therefore will not be described in detail.
- the first and second trays (15, 45) of the third embodiment have support members (38; 68) extending from the rim (21; 51). respective first and second trays to the middle plane of the bottom (16; 46) thereof.
- these support elements (38; 68) are in the form of wells opening into the upper face of the assembly flange.
- the wells (38, 68) have an ellipsoidal cross section which gives a good stiffness to bending with respect to their bulk, but they could have any other section and in particular a circular, square or polygonal section. .
- the overall shape of the section of the wells must be considered, it being understood that the wells may have grooves, ribs or other reliefs on their outer face - and / or inter-ear-pe, in particular-- to - increase the frictional retaining force.
- the wells (38; 68) each provide a third fulcrum (27; 57) and a fourth fulcrum (28; 58) in addition to the first and second fulcrums (25,26; 56) formed on the free end of the assembly flange (21; 51).
- These third and fourth points of support (27, 28, 57, 58). are located at the lower end of the wells on the portion of the outer face disposed facing the assembly side (19; 49). The end The bottom of the wells is close to the mean plane of the bottom of the tray in order to increase the stability thereof when it rests on the edge.
- the base ' made allows to arrange the trays (15, 45) with their upper face provided with the printed lid slightly inclined relative to the vertical, when it rests on a horizontal plane whose trace Pl for the first tray and the trace P2 for the second tray are visible in Figure 20 ' .
- the lower end of the wells 38 of the first tray '15 is in the median plane of the bottom 16, which provides support in line with the rim of one assembly and avoids any tilting of the first tray 15 when exerting pressure on its assembly flange 21, similarly to the wings (34,35) of the second embodiment.
- the lower end of the wells 68 of the second tray is also located near the middle plane of the bottom 46 thereof, which increases the stability of the second tray 45 when used flat.
- tray " 15 ⁇ is adapted ⁇ ⁇ ⁇ section " outer wells 68 of the second tray 45 so that they can be engaged frictionally in the wells 38 of the first tray.
- the wells (38, 68) thus form the complementary hooking means (24, 54) for the first and second containers (15, 45).
- the wells can also perform a coding function prohibiting .the assembly of two identical trays, which allows for a packaging system providing varied and balanced meals, as in the first two embodiments.
- FIGS. 22 and 23 show a variant of the third embodiment which has a lot of similarity with it, in particular with a second container 45 visible in section in FIG. 23, which has a periphery 48 and an annular wall 47 of section similar to that shown in Figure 17.
- the wells * 38 circular in section with a portion 39 of reduced cross-section, that is to say - of smaller section than a section of the well nearest outlet in the assembly flange 21 and less than a section located closer to the lower end 27 of the well 38.
- the well 38 has from its upper outlet, a first slightly frustoconical portion which goes into tapering to the minimum diameter portion 39, and then a lower portion extending flaring toward the bottom of the well to which it is connected by a rounded.
- the second tray has a well 68 of similar shape, that is to say with a portion of reduced section 69.
- the wells 38, 68 of this variant of the third embodiment are also designed so that they can be engaged into each other so as to form hooking means (24,54), and allow ; It is not necessary to engage two identical trays one inside the other so that they also form polarizing means.
- the portion of reduced section 39. forms a hard point during the insertion of the well 68 in the well 38 of the first tray. Once this hard point is passed by elastic deformation of the plastic material, the wells are held one in the other in the assembled position. A snap-in phenomenon is thus obtained between the wells (38, 68) of the first and second trays (15, 45), in addition to or in place of the frictional engagement. Such cooperation 'snap indicates to the user that the first and second trays are hooked together.
- the gripping force can be determined by the geometry of the wells more precisely by means of a snap than by a simple frictional cooperation.
- the gripping force is greater than the weight of the first tray 15 in which are inserted the wells 68 of the second tray 45, so that when the user wears the assembled system only to the using the second tray 45, there is no risk of falling of the first tray 15. Therefore, it is preferable that the disengagement of the wells (38,68) requires a determined force greater than the weight of each of the trays. , or at least greater than the weight of the tray that is suspended from the other when carried with one hand.
- the determined force necessary to disengage the hooking means (24, 54) formed by the wells (38, 68) is so high that the first and second trays can not be separated. manually. But it will be preferred that this determined force remains reasonable so that an adult can easily separate the trays, for example in order to heat only one of the two trays. On the other hand, it can be predicted that the determined force required for the disengagement is large enough that a young child can not separate the first and second trays (15,45).
- the critical point for achieving snap-in cooperation is the inner section of the well 38 with respect to the outer section of the well 68, and more particularly the reduced sections 39 and 69 of each of these wells.
- annular side wall 17 has an annular recess 17a which serves to stiffen it.
- the bottoms (16, 46) of the first and second trays (15, 45) each have a boss (16a, 46a).
- the periphery 18 of the opening of the first tray 15 has along the assembly side 19 a curved portion, here concave, which is of complementary shape to the corresponding portion of the periphery 48 of the second tray 45, that is to say located on the side of the assembly 49, which has a convex curvature.
- This arrangement makes it possible to minimize the width of each of the assembly flanges (21, 51) between the protruding corrugations (32; 52), and consequently to increase the rigidity of the assembled system.
- the free end 22 of the assembly flange 21 of the first tray present. in its median part a complementary curvature at the periphery 48 of the opening of the second tray 45, and a width adapted to come ' under the assembly flange 51 in the immediate vicinity of the annular wall 47 of the second tray.
- the assembly flange 21 located below, the assembly flange 51 of the other tray forms an additional keying means.
- the side of the annular wall 17 has a curved surface, here concave, along the assembly side 19.
- This concave curved surface is complementary to the portion of the corresponding annular wall 47. of the second tray 45, which forms a convex curved surface. This allows the receptacles (14, 44) to better occupy the space between the assembled containers (15, 45), and therefore to contain a larger quantity of food for a given size of the packaging system (10, 40). ) assembled.
- the trays made according to the third embodiment and its variant can be advantageously manufactured by thermoforming, that is to say by stamping a sheet of heated plastic material. This inexpensive manufacturing process can be integrated into a packaging filling line.
- first tray according to one of the. embodiments with a container made in another mode implementation, and possibly to design a food packaging system with more than two trays.
