Definitions
- the present invention relates to an open tray of cardboard sheet material of the type comprising a belt of side walls connected to a bottom by first fold lines, namely two first opposite side walls respectively connected on either side at two seconds opposite side walls, via end flaps to form reinforced corner corners.
- the present invention v to provide a tray and a blank meeting better than those previously known to the requirements of practice, in particular in that it allows to make visible at least partly the products contained in the tray and in that it allows a significant saving of cardboard, thus resulting in a more attractive cost price. To do this, it starts in particular from the idea of using at least partly the contents of the packaging to support the upper trays during stacking.
- the invention essentially provides an open tray of cardboard sheet material comprising a belt of side walls connected to a bottom by first fold lines, namely two opposite first walls respectively connected to two opposite second side walls via end flaps to form reinforced corner corners, characterized in that the two corner corners on the same diagonal are of a first height and the other two corner corners on the opposite diagonal are of a second height smaller than the first height.
- the first walls have a rectangular trapezoidal shape; the first walls are formed by at least two rectangular or substantially rectangular parts of different heights; the second walls have a rectangular trapezoidal shape; the second walls are formed by at least two rectangular or substantially rectangular parts of different heights; the first walls are respectively connected on either side by second fold lines to the end flaps; two end flaps are connected to the first walls on the side of greatest height and the other two flaps are connected to the second side walls of the side of smallest height; the corner corners of the tray of a first height are provided with stacking lugs, arranged to cooperate with corresponding orifices, of complementary shape, located in the bottom of the tray.
- the invention also provides a blank for forming a tray comprising a rectangular central panel provided on each side with a flap, namely two opposite first flaps and two opposite second flaps, characterized in that the first flaps have a part d end of a first height and the other end portion of a second height different from said first height, said first flaps being symmetrical with respect to the center of the central panel.
- first flaps are respectively connected on either side by first fold lines to end flaps and the second flaps are devoid of flaps.
- two flaps are connected to the first flaps on the side of the greatest height, and the other two flaps are connected to the second flaps on the side of the smallest height.
- each first flap has a rectangular trapezoidal shape.
- each first flap is formed by at least two rectangular or substantially rectangular parts of different heights.
- the invention also advantageously proposes a blank characterized in that the second flaps have a rectangular trapezoidal shape, or are formed by at least two rectangular or substantially rectangular parts of different heights.
- the invention also provides a set of blanks of the type described above, characterized in that it consists of a series of adjacent blanks, flat, the outer edges relative to the central panel of the first flaps and flap of each blank being joined, over their entire lengths (strictly 'or substantially all their lengths, with the outer edges of the first flaps of the blank immediately adjacent.
- the assembly is characterized in that, in addition, the outer edges with respect to the central panel of the second flaps and of the flaps of the first corresponding flaps of at least two adjacent blanks are also joined together, two by two .
- the invention will be better understood on reading the embodiments given below by way of nonlimiting examples.
- Figure 1 is a top view of a blank for tray of known type.
- Figure 2 shows, in perspective, two trays sheaves one on the other, obtained with blanks according to Figure 1 of the prior art.
- Figure 3 is a top view of a first embodiment of a blank according to the invention.
- Figure 4 is a perspective view of two trays stacked one on the other obtained with blanks according to Figure 3.
- - Figure 5 is a plan view of a set of nested blanks of the type described with reference to Figure 3.
- Figure 6 is a plan view of a set of nested blanks, according to another embodiment of one invention.
- Figures 7 and 8 are two plan views of blank assemblies according to other embodiments of the invention.
- FIGS 9 and 10 show two plan views of blank assemblies according to two other embodiments of the invention with double nesting.
- the same reference numbers are used to designate the identical blank and tray elements.
- Figures 1 and 2 show a blank l, and trays 1 obtained with such blanks, in double-sided corrugated cardboard sheet, according to the prior art, comprising a belt 2 of side walls or rectangular flaps, namely two first flaps opposite 3 and 4, and two second opposite flaps 5 and 6, of shorter length than the first flaps.
- the walls are connected by first fold lines 7, perpendicular two by two, to a rectangular central panel 8 forming the bottom of the tray.
- the two walls obtained from the first flaps 3 and 4 opposite, are of the same height over their entire length and of equal height between them.
- second fold lines 9 perpendicular or substantially perpendicular to the first fold lines, to rectangular end flaps 10, of the same height as the first flaps and of the same transverse dimension, or width, as the second adjacent walls 5 and 6, which are rectangular or substantially rectangular and devoid of ra ats.
- the plate 1 also comprises four corner pins 11, constituted for example by rectangular parts projecting from the upper edge 12, external with respect to the central panel, first side walls or first flaps 3 and 4.
- Each rectangular part constituting said studs is astride, and symmetrical with respect to, the corresponding second fold line 9, to form said studs which adopt, when the plate is formed, an angle shape rectangular arranged to fit (Cf. Figure 2) in open recesses or slots 13, formed at the end and straddling the first fold lines 7 of junction between shutters and central panel.
- the slots 13 therefore form stacking orifices 14, in the form of angles angled at right angles to a shape complementary to that of the studs 11 when the plate is formed.
- Openings 15 are moreover, and for example, formed, centered with respect to the first fold lines 7 of junction of the second flaps 5 and 6, to allow the gripping of the trays sheaves one on the other, as shown.
- Figures 3 and 4 show a first embodiment of blank and tray 16 according to the invention, in sheet of double-sided corrugated cardboard, which differs from the blanks and trays previously described, in that the first flaps 17 and 17 'are here , no longer rectangular, but trapezoidal, one end part 18, 18 ', flaps being of greater height than the other end 19, 19', for example equal to twice its height.
- the first flaps are also symmetrical with respect to the center 20 of the rectangular central panel 21.
- the flaps 22 and 23 (22 ', 23') connected to the flaps 17 (17 ') by second fold lines 24 perpendicular to the first fold lines 25 are for example of identical height at the ends to which they are attached, and likewise length than the second adjacent flaps 26.
- the second flaps 26 are rectangular, identical, and for example of the same height as the small end 19, 19 '.
- the blanks and trays 16 according to the embodiment of the invention more particularly described here include stacking pins 27, straddling the upper edge of the two ends 18 and 18 'of greater height and adjacent flaps 23, of the type of pins 11 described with reference to Figures 1 and 2, as well as openings 28, in the lower part of the flaps at the junction lines with the bottom, corresponding to the openings 14, at the four lower corners of the tray, thus allowing stacking by presenting the trays in both directions.
- the other end 19 and 19 'of small height for its part, comprises, instead of a tenon, a recess of a shape complementary to that of the tenon, which will allow an edge-to-edge embedding of the blanks during the manufacture of these, as shown in Figures 5 to 10.
- the height of the parts 18 and 18 ′, below the tenon 27, of the plate corresponds to a height of product 29, (in phantom in Figure 4), intended to be contained by the plate, products which to provide rigidity and support for the angle 30 of lower height of the upper plate, during stacking.
- FIG. 5 shows a board or sheet 31 of corrugated cardboard, cut for example by simultaneous assembly of two blanks or four adjacent blanks
- the blanks are here cut according to two longitudinal columns 32, 32 ', in the cardboard width.
- the external edges 33a, 33 ′ has first flaps of the blanks 33, 33 ′, fit perfectly into one another, and are joined with the external edges 34a, 34a ′ of the first flaps of the blanks 34, 34 'of the adjacent lines, including at the studs 35, 36 and the second flaps, without no loss of cardboard.
- the blanks of the two columns are also contiguous or substantially contiguous at the level of the external edge 37 of their second adjacent flaps 38 and 38 ′.
- FIG. 6 shows a sheet 40 of corrugated cardboard also allowing the nesting of the first flaps 41 and 42 of two adjacent blanks 43 and 44.
- each first flap has two adjacent portions 45 and 46 which are substantially rectangular, namely a first portion 45 of great height and a second portion
- the two rectangular portions 45 and 46 may also not be adjacent, for example by being connected by an intermediate trapezoidal portion or forming a rectangular intermediate bearing.
- recesses 47 of shape complementary to that of the pins 48, allow an interlocking edge to edge of the first flaps facing two adjacent blanks.
- Figures 7 and 8 show another arrangement of blanks 50 and 60 according to the invention, the first flaps of a row being fitted with the first adjacent flaps of the next row of blanks and this time being shorter length than the second flaps, which allows for example to provide three adjacent blank columns 51, 52 and 53 or 61, 62 and 63, the outer edges of their second flaps being contiguous and opposite in the transverse direction .
- Figures 9 and 10 show other embodiments of blanks and set of blanks 70 and 80 according to the invention in which the second flaps 71 and 81 are of identical or similar shape to the shape first flaps 72 and 82, therefore having two ends of different heights.
- the small height 73 of the second flaps is located on the side of the small height 74 of the first flaps and is for example equal to the latter.
- the great height 75 of the second flaps is for example equal to the great height 76 of the first flaps.
- the flaps 77, 87, 78 and 88 are in turn arranged to allow an optimization of the consumption of cardboard and have end edges, 77a and 77b for the flaps on the side of the great height, 78a and 78b for the flaps on the side of the small height, symmetrical in shape with respect to the center 79 of a rectangle 79 'in which said flaps are inscribed, said rectangle 79' being formed by the second fold lines of said flaps with their adjacent flap, and complementary with the end edges of the flaps of the adjacent blank, so as to minimize cardboard scraps, as shown in the figures.
- Such a configuration of the second flaps and of the flaps allows an optimization of the cutting of the sets of blanks in all the directions of development of the plane, longitudinal and transversely, thus optimizing the use of the sheet of corrugated cardboard to be cut whose width is determined.
- the present invention is not limited to the embodiments more particularly described, but er. on the contrary embraces all variants and in particular those where the small height is zero, those where the stacking lugs are not straddling the corners, but on the first flap and / or on the second large flap height, those where the second fold lines are inclined inward to form a tray of isosceles trapezoidal cross section.
