Description

Title of the invention: Cardboard box for storing and transporting eggs

[0001] The present invention relates to a cardboard box for storing and transporting eggs.

[0002] It also relates to a blank and a method of making the box from said blank.

[0003] Well-known egg boxes, molded from paper pulp using a paper process mechanized chewing, allow the storage and transport of eggs.

[0004] They comprise a tray usually having two rows of three cells forming a housing or six cells capable of receiving half a dozen or a dozen eggs. Each of the cells is adapted to receive one of the two opposite peaks of an egg, the other peak remaining free. Furthermore, the tray is rectangular and it has four edges opposite each other, two large edges and two small edges.

[0005] Also, the box has a hollow lid mounted hinged on one of the large edges of the tray so that it can be folded down and cover the top of the eggs. In this way, the eggs are kept in a fixed position and at a distance from each other and cannot collide during transport. In addition, the boxes can be stacked on top of each other without fear of the eggs being crushed.

[0006] However, the production of such boxes requires a facility dedicated to shaping the paper pulp.

[0007] Also, it was imagined to produce such a box in flat cardboard. Thus, the box comprises, on the one hand, a tray having a bottom and four walls erected two by two facing each other, and on the other hand, a support plate having at least one row of orifices. The support plate is held on the edges of the tray at a distance and facing the bottom so as to be able to accommodate eggs respectively through the orifices. Each of the eggs has a top extending between the support plate and the bottom.

[0008] In addition, advantage is taken of the cardboard cut out of the support plate to make the holes, to provide wedging tabs against which the top of the eggs extending towards the bottom of the tray can come to rest.

[0009] However, although such wedging tabs allow the eggs to be protected from shocks to a certain extent, they are not completely held in a fixed position in the orifices.

[0010] Also, a problem which arises and which the present invention aims to solve is to ensure better holding of the eggs in the tray.

[0011] For this purpose, and according to a first object, there is proposed a cardboard box for storing and transporting eggs, comprising: a tray having a bottom and four walls erected two by two opposite each other, said erected walls respectively defining four opposite edges two by two; a support plate having at least one row of a plurality of orifices, each of the orifices being delimited by an orifice edge, said support plate being adapted to be held on said edges of said tray at a distance from said bottom so as to be able to accommodate a plurality of eggs respectively through said plurality of orifices, each of the eggs having a top extending between said support plate and said bottom.

[0012] And the cardboard box further comprises, for each of said orifices, a rim secured to said orifice edge and extending obliquely in line with the orifice to said bottom in order to be able to accommodate said top and keep the eggs in a fixed position.

[0013] Thus, a characteristic of the invention lies in the implementation of the bezel obliquely between the support plate and the bottom of the tray at the right of the orifice. In this way, the wall of the egg is not only circularly engaged against the edge of the orifice, but in addition, the top is also engaged in the inner edge of the bezel, from the support plate to the bottom of the tray.

[0014] In other words, if we consider the single axis of symmetry of an egg, the latter passes through the telescope.

[0015] As a result, the egg is held in a fixed position inside the tray and its orientation remains throughout the egg packaging line.

[0016] Preferably, each of the glasses of said orifices has one end secured to said orifice edge and an opposite end engaged with said bottom. In this way, the glasses are themselves held in a fixed position and obliquely between the support plate and the bottom of the tray. Therefore, the eggs are themselves held in a fixed position in a direction substantially perpendicular to the support plate and the bottom of the tray.

[0017] Also, said bottom advantageously has a plurality of slots adapted to receive the opposite ends of said glasses respectively. According to a particularly advantageous embodiment, the slots are arranged in an arc of a circle to accommodate the opposite end of the glasses. In this way, better connection of the glasses and the bottom of the tray is obtained.

[0018] Furthermore, the glasses of said plurality of orifices extend along the same mean plane. In other words, the glasses of the plurality of orifices of said at least one row extend along the same mean plane. In this way, the eggs engaged through the orifices of the plurality of orifices all extend substantially in the same direction.

[0019] In addition, said bezel has an inner edge whose shape is substantially that of the meridian of an ovoid. In this way, the inner edge of the bezel perfectly matches the surface of the eggs along two lines extending from the pole of the egg, including it, to the circular line where it is engaged against the edge of the orifice.

[0020] As a result, the eggs cannot tip relative to the support plate and the tray.

[0021] Furthermore, and according to a particularly advantageous embodiment, said support plate comprises two rows of a plurality of orifices, separated from one another by a median strip, and each of the orifices of one of said rows is symmetrical to an orifice of the other of said rows with respect to said median strip.

[0022] In this way, when all the holes accommodate an egg, the box is perfectly balanced. This embodiment makes it easier to package the eggs and ensures their transport without the risk of them breaking.

[0023] Also, said median strip defines a portion of each of the orifice edges of said two rows of pluralities of orifices and each of the bezels is integral with said portion of each of the orifice edges. In other words, the median strip defines on each side the orifice edges of the two rows. And the bezels of two contiguous orifices extending on each side of the median strip extend opposite each other towards the bottom of the tray.

[0024] Furthermore, the box advantageously comprises a hollow lid mounted hinged on one of said edges of said tray, while each of the eggs has an opposite top extending opposite said bottom relative to said support plate, and said lid is adapted to be folded down to cover said opposite top of said eggs. In this way, the eggs are completely covered and protected from the environment. In addition, the boxes can be stacked without risk of the eggs breaking.

[0025] According to another object of the invention, there is provided a blank made from a cardboard plate to be able to form a box as described above. The blank comprises: a first rectangular panel and two first flaps opposite each other hinged on said first panel along two first fold lines parallel to each other, said two first flaps respectively having two first opposite assembly tabs; two first free flaps opposite each other and hinged on said first panel along two other first fold lines perpendicular to said first fold lines; and, a second panel mounted hinged on one of said first flaps, said second panel having at least one row of a plurality of horseshoe cutouts.

[0026] In this way, a cardboard box for storing and transporting eggs is produced from flat cardboard and not from molded cardboard. The flat cardboard used is, for example, double-sided corrugated cardboard. Thus, it comprises a sheet of corrugated paper and two sheets of flat paper glued on each side. This type of cardboard has the double advantage of being relatively rigid in relation to its weight per square meter, and of being able to absorb shocks by deformation. As will be explained below, such an egg box is easy to make from corrugated cardboard, at an advantageous cost, with standard installation.

[0027] Furthermore, thanks to the horseshoe cutout inside the second panel, both the orifice edge and the bezel are produced, through which the top of the egg engages, as will be explained below.

[0028] Preferably, the blank further comprises: a third rectangular panel and two second flaps opposite each other, hinged on said third panel along two second fold lines parallel to each other, said two second flaps respectively having two second opposite assembly tabs, while one of said second flaps and the other of said first flaps are connected together along a hinge fold line parallel to said first and second fold lines; and, two second free flaps opposite each other and hinged on said third panel along two other second fold lines perpendicular to said second fold lines.

[0029] As will be explained below, the one-piece blank makes it possible to form both the tray with the support plate and also with a lid.

[0030] In this way, and according to yet another object, there is provided a method of producing a box as described above and comprising the following steps: a blank of the type also described above is provided; said first flaps are erected respectively with respect to said first panel; said first assembly tabs are folded down; said first free flaps are erected and connected respectively to said first assembly tabs; and, said second panel is folded down towards said first panel to carry it on said first flaps and first free flaps erected.

[0031] Such a box is then produced at an advantageous cost from a single piece.

[0032] In addition, a blank is advantageously provided comprising the third panel and the second flaps and the second free flaps as described above and, according to the method according to the invention: said second flaps are erected relative to said third panel, while said one of said second flaps and said one of said first flaps are articulated relative to each other along said hinge fold line; said second assembly tabs are folded down; and, said second free flaps are erected and connected respectively to said second assembly tabs.

[0033] Other features and advantages of the invention will emerge from reading the description given below of a particular embodiment of the invention, given as a indicative but not limiting, with reference to the attached drawings in which:

[0034] [Fig-1] is a schematic top view of an element of the invention making it possible to produce a cardboard box in accordance with the invention;

[0035] [Fig.2] is a schematic three-quarter perspective view of the object of the invention produced by means of the element shown in [Fig.l]; and,

[0036] [Fig.3] is a schematic side perspective view of the object of [Fig.2] including an additional element.

[0037] [Fig. 1] shows a blank 10 made from a double-sided corrugated cardboard sheet. In other words, the blank 10 is made from a cardboard comprising fluted paper between two sheets of flat paper glued on each side. Such a corrugated cardboard sheet is called “rigid” or “semi-rigid”, because it can be folded manually under stress.

[0038] The blank 10 extends longitudinally and has a longitudinal median line M dividing it into two portions symmetrical to each other with respect to said median line M. It comprises on the one hand a first central part 12 adapted to cooperate with a second part 14, and on the other hand a third part 16 opposite the second part 14 with respect to the first part 12, adapted to cooperate with the other two parts.

[0039] The first part 12 comprises a first rectangular panel 18 and two first longitudinal flaps 20, 22 opposite each other with respect to the first rectangular panel 18 and articulated on the first panel 18 along two first longitudinal fold lines parallel to each other, 24, 26.

[0040] Also, the two first longitudinal flaps each have at their ends, respectively two first assembly tabs 28, 30, opposite one another and of substantially triangular shape. The first assembly tabs 28, 30 are articulated at the end of the first longitudinal flaps 20, 22 along first fold lines 32, 34 oriented at substantially more than 90° relative to the two first longitudinal fold lines 24, 26, for example 95°. The consequences of this inclination will be explained in more detail in the remainder of the description.

[0041] The first part 12 also comprises two first free flaps 36, 38 that are isosceles trapezoidal and opposite each other relative to the first panel 18. The small side of the first free flaps 36, 38 is connected to the first panel 18, on which they are articulated along two first transverse fold lines 40, 42 that are perpendicular to the first longitudinal fold lines 24, 26. It will be observed that the first two longitudinal fold lines 24, 26 and the first two transverse fold lines 40, 42 delimit the first panel 18.

[0042] Furthermore, the first two longitudinal flaps 20, 22 and the first two free flaps 36, 38 have a width substantially equal to one third of the width of the first panel 18. Also, the length of the first panel 18 is substantially equal to 7 / 4 of its width according to a first variant embodiment. The first panel 18 has a length substantially less than 150 mm for example according to this first variant.

[0043] Opposite the third part 16, the second part 14 comprises a second panel 44 articulated on the first longitudinal flap 22 opposite the other first longitudinal flap 20. The second panel 44 is articulated on the first longitudinal flap 22 along a first second fold line 46.

[0044] Also, the second panel 44 has a length substantially greater than the length of the first panel 18. Also, according to the example provided above, its length is substantially greater than 150 mm. Furthermore, its width is close to two-thirds of its length.

[0045] Furthermore, the second panel 44 has two rows, one proximal 48, the other distal 50, of three horseshoe-shaped cutouts 52, 54, 56; 58, 60, 62. The two rows 48, 50 are separated from each other by a rectilinear transverse median portion 64 of the second panel 44 and extending from one transverse edge 66 to another opposite transverse edge 68.

[0046] Also, each of the horseshoe-shaped cutouts 52, 54, 56; 58, 60, 62, has a rounded end 70 opposite the transverse middle portion 64, and two branches opposite each other 72, 74, joining the transverse middle portion 64 with which they are integral. Only the elements of the cutouts 52, 72 are referenced for reasons of clarity.

[0047] Furthermore, it will be observed that the cutouts 58, 60, 62 of the proximal row 48 are respectively symmetrical to the cutouts 52, 54, 56 of the distal row 50 with respect to the transverse median portion 64.

[0048] In addition, these horseshoe cutouts 52, 54, 56; 58, 60, 62, have a continuous internal cutting line 76 looped on itself allowing the center of each of the cutouts to be detached from the blank 10. Only the internal cutting line 76 of one of the horseshoe cutouts 52 is shown, also for the clarity of the drawing.

[0049] It will also be observed that this interior cutting line 76 is substantially ovoid with a swollen part towards the rounded end 70 of the cutouts.

[0050] Furthermore, the second panel 44 has a free edge 78 opposite the first longitudinal flap 22. This free edge 78 has two recesses 80, 82 symmetrical to each other with respect to the longitudinal median line M so as to be able to form three connecting portions, a median connecting portion 84, and two peripheral connecting portions 86, 88 symmetrical to each other with respect to the median lesion portion 84.

[0051] The function of these connecting portions 84, 86, 88 will be explained in detail below. of the description.

[0052] Before describing in more detail the third part 16 of the blank 10, it will be observed that the first panel 18 comprises two rows 90, 92 of three arcuate slots 94, 96, 98; 100, 102, 104. It will be observed that the concavity of the arcuate slots 94, 96, 98; 100, 102, 104 are respectively oriented towards the first longitudinal folding lines parallel to each other, 26, 24 of which they are respectively contiguous.

[0053] In addition, the arc-shaped lights 94, 96, 98; 100, 102, 104 are distributed in the first panel 18 according to a symmetry corresponding to that of the distribution of the horseshoe-shaped cutouts 52, 54, 56; 58, 60, 62 of the second panel 44.

[0054] The third part 16 comprises a third rectangular panel 106 and two second longitudinal flaps 108, 110 opposite each other with respect to the third rectangular panel 106. One of the second longitudinal flaps 108 is connected to one of the two first longitudinal flaps 20 of the first part 12. They are connected to each other by their large common edge 112. Also, they are demarcated from each other by a fold line 114, which is parallel to the first longitudinal fold lines 24, 26.

[0055] The two second longitudinal flaps 108, 110 are articulated on the second rectangular panel 106 along two second longitudinal fold lines parallel to each other 116, 118. The fold line 114 is also parallel to the two second fold lines 116, 118.

[0056] Furthermore, the two second longitudinal flaps 108, 110 have at each of their ends two second assembly tabs 120, 122. They have a substantially triangular shape. In addition, they are articulated at the end of the second longitudinal flaps 108, 110, along second fold lines 124, 126. These fold lines 124, 126 are oriented at more than 90° relative to the two second longitudinal fold lines 116, 118, for example at 95°.

[0057] The third part 16 comprises two second free flaps 128, 130 that are isosceles trapezoidal and opposite each other with respect to the third panel 106. The short sides of the second free flaps 128, 130 are connected to the third panel 106 on which they are articulated along two second transverse folding lines 132, 134, which are perpendicular to the two second longitudinal folding lines 116, 118.

[0058] Furthermore, the two second longitudinal fold lines 116, 118 and the two second transverse fold lines 132, 134 then delimit the second panel 106.

[0059] Also, one of the two second longitudinal flaps 108, linked to the first longitudinal flap 20, has a width substantially equal to that of the latter, while the other second longitudinal flap 110 has a substantially greater width.

[0060] In addition, the blank 10 has, on the fold line 114, three anchoring recesses, a central one 136 cut by the longitudinal median line M, and two others 138, 140 opposite each other with respect to the median line M. These recesses 136, 138, 140 extend longitudinally and are substantially bulged in the center. Furthermore, their two ends are concave.

[0061] Thus, thanks to the blank 10 described above, and in accordance with the invention, a cardboard box is produced for the storage and transport of eggs. A first phase of the production of the box will be explained with reference to [Fig. 1] and [Fig. 2].

[0062] First of all, the first two longitudinal flaps 20, 22 are erected relative to the first panel 18 and the two second longitudinal flaps 108, 110 relative to the third panel 106. Consequently, the first flap 20 and the second flap 108 fold relative to each other along the fold line 114.

[0063] Thus, the folding of the first flap 20 and the second flap 108 causes two dovetail anchoring tenons to emerge between the successive anchoring recesses 138, 136, 140.

[0064] Then, the two first assembly tabs 28, 30 of the two first longitudinal flaps 20, 22 are folded down, respectively along their first substantially inclined fold lines 32, 34, and the two second assembly tabs 120, 122 of the two second longitudinal flaps 108, 110 along their second substantially inclined fold line 124, 126.

[0065] Then the first free flaps 36, 38 are erected relative to the first panel 18, and the second free flaps 128, 130 relative to the third panel 106. Then the 2 x 2 first assembly tabs 28, 30 are glued, on the one hand, against the inside of the two first free flaps 36, 38 and, on the other hand, the 2 x 2 second assembly tabs 120, 122 against the inside of the second free flaps 128, 130.

[0066] In this way, a tray 142 of conical shape is obtained, as illustrated in [Fig. 2], and a hollow cover 144 hinged on the tray 142 along a rear edge 146 of the tray 142, which rear edge 146 corresponds to the fold line 114.

[0067] The tray 142 thus has a bottom 148 corresponding to the first panel 18 and four walls erected two by two facing each other, a rear wall 150 facing a front wall 152, corresponding to the first two longitudinal flaps 20, 22 and two facing side walls 154, 156, corresponding to the first two free flaps 36, 38.

[0068] Then, after having detached from the blank 10, the center of each of the six horseshoe cutouts 52, 54, 56; 58, 60, 62, the second panel 44 is then folded towards the tray 142 along the first second fold line 46.

[0069] And we apply the second panel 44 against the two free lateral edges of the two facing side walls 154, 156 and against the rear edge 146 of the rear wall 150. Thus, the two dovetail anchoring tenons respectively engage in the two recesses 80, 82 of the free edge 78.

[0070] The second panel 44 then forms a support plate 158, while its transverse middle portion 64 forms a middle strip 159.

[0071] The horseshoe-shaped cutouts 52, 54, 56; 58, 60, 62 are then detached and pivoted around the central strip 159, towards the bottom 148.

[0072] Two rear rows 160 and front rows 162 of three orifices 164, 166, 168; 170, 172, 174 are thus released, while two corresponding rows of six bezels 176, 178, 180; 182, 184, 186 are revealed. And the release of the orifices 164, 166, 168; 170, 172, 174 reveals for each of them an orifice edge 175, which is free.

[0073] The rounded end 70 of each of the six horseshoe-shaped cutouts 52, 54, 56; 58, 60, 62 then forms a rounded free end 188 of the six corresponding bezels 176, 178, 180; 182, 184, 186.

[0074] The rounded free ends 188 of the six bezels 176, 178, 180; 182, 184, 186 are then respectively engaged in the six arcuate slots 104, 102, 100; 98, 96, 94 of the first panel 14. The rounded free end 188 of a single bezel 176 is referenced as engaged through the arcuate slot 104, for greater clarity of the drawing.

[0075] Thanks to the arc shape of the six lights 104, 102, 100; 98, 96, 94, a better blocking of the rounded free ends 188 of the six glasses 176, 178, 180; 182, 184, 186 in the bottom 148 of the tray 142 is obtained.

[0076] Thus, a rear row of the three glasses 176, 178, 180 extends from the median strip 159 obliquely to the bottom 148 along the same average plane. They are oriented towards the rear wall 150 and they extend respectively in line with the three orifices 164, 166, 168 of the rear row 160.

[0077] Conversely, with respect to the median strip 159, a front row of the three other glasses 182, 184, 186 extends from the median strip 159 obliquely to the bottom 148 along another same mean plane. They are then oriented towards the front wall 152 and they extend respectively in line with the three orifices 170, 172, 174 of the front row 162.

[0078] Thus, the detachment of the center of each of the six horseshoe-shaped cutouts 52, 54, 56; 58, 60, 62, from the aforementioned blank 10, releases an inner edge 190 of each of the bezels 176, 178, 180; 182, 184, 186. Only the lower edges 190 of certain bezels 178, 184, and 186 are referenced for reasons of clarity of the drawing.

[0079] This produces a cardboard box 192 in accordance with the invention allowing the storage of eggs.

[0080] We will refer to [Fig.3] on which we find the cardboard box 192 seen from side and in which an egg 194 is engaged through the single orifice 164 of the proximal row 160.

[0081] Thus, the egg 194 has two opposite vertices, a more swollen vertex 196, and an opposite less swollen vertex 198. Also, it has two opposite poles, a North pole 200 located in the more swollen vertex 196 and a South pole 202 located in the less swollen vertex 198. The egg 194 has a single axis of circular symmetry A.

[0082] The less bulging apex 198 of the egg 194 is engaged through the bezel 176, and it is engaged both in the orifice edge 175 of the substantially circular orifice 164 and in the inner edge 190 of the bezel 176.

[0083] Thus, the orifice edge 175 substantially circularly hugs the egg along a parallel thereof, while the inner edge 190 hugs the less swollen apex 198 of the egg along a curve of the egg closed on itself and substantially flat extending obliquely, from the median band 159 to the south pole 202 including it.

[0084] In this way, the egg is held in a fixed position, its axis of circular symmetry being substantially perpendicular to the bottom 148 and also to the support plate 158.

[0085] The other orifices 166, 168; 170, 172, 174, are adapted to receive eggs in the same way. And they are also held in a fixed position in the same orientation by means of the glasses 178, 180; 182, 184, 186.

[0086] Then, the cover 144 can be folded down onto the tray 142 to cover the swollen top 196 of the eggs 194.

[0087] Therefore, the free edge 78 is carried and folded by the second longitudinal flap 108, as the cover 144 folds down.

[0088] Obviously, such a cardboard box is not limited to two rows of three holes. The invention also extends, for example, to cardboard boxes including two rows of six holes respectively associated with 2 x 6 glasses.

[0089] In addition, cardboard boxes can be stacked without the risk of breaking the eggs.
