Description

The present invention relates to a multi-piece blank of corrugated cardboard or cartonboard, and a container obtained from folding such a blank. As it is known, corrugated cardboard is composed of a fluted paper core sandwiched between and bonded to inner and outer paper face liners . According to the prior art, any kind of box is produced from one or more specific blanks of corrugated cardboard or cartonboard in dependence on the intended use and distribution channel. Hence, the present trends towards multiple formats, smaller volumes and customization dramatically increase the burden on production lines for adapting to such different requirements . One object of the present invention is thus reducing the burden imposed by such articulated and various requirements on the production lines. According to the present invention, this object is achieved by means of a multi-piece blank comprising: - a chassis of corrugated cardboard or cartonboard having at least two first parallel crease lines, and a second and a third crease line intersecting said at least two first parallel crease lines, wherein said first, second and third crease lines define a series of at quadrangular bottom panel least a first lateral panel, a and a second lateral panel, wherein said second crease line defines a first corner flap, a third lateral panel and a second corner flap connected to the first lateral panel, bottom panel and second lateral panel, respectively, wherein said third crease line defines a third corner flap, a fourth lateral panel and a fourth corner flap connected to the first lateral panel, bottom panel and second lateral panel, respectively, - at least one compression member of corrugated cardboard or cartonboard having a fourth crease line contiguous and parallel to one of said first, second and third crease lines and defining a first portion and a second portion in said at least one compression member, at least one of said first portion and second portion being glued to at least one of respective areas of an internal surface of the chassis, wherein at least one of said first portion and second portion protrudes beyond a top edge of at least one of said lateral panels and corner flaps opposite to said bottom panel, and comprises a protruding area configured to bear graphic or text elements. A further subject-matter of the present invention is constituted by a container obtained from a multi-piece blank comprising: - a chassis of corrugated cardboard or cartonboard having at least two first parallel crease lines, and a second and a third crease line intersecting said at least two first parallel crease lines, wherein said first, second and third crease lines define a series of at least a first lateral panel, a quadrangular bottom panel and a second lateral panel, wherein said second crease line defines a first corner flap, a third lateral panel and a second corner flap connected to the first lateral panel, bottom panel and second lateral panel, respectively, wherein said third crease line defines a third corner flap, a fourth lateral panel and a fourth corner flap connected to the first lateral panel, bottom panel and second lateral panel, respectively, - at least one compression member of corrugated cardboard or cartonboard having a fourth crease line contiguous and parallel to one of said first, second and third crease lines and defining a first portion and a second portion in said at least one compression member, at least one of said first portion and second portion being glued to at least one of respective areas of an internal surface of the chassis, wherein at least one of said first portion and second portion protrudes beyond a top edge of at least one of said lateral panels and corner flaps opposite to said bottom panel, and comprises a protruding area configured to bear graphic or text elements, wherein the first and second lateral panel are folded at 90° about the respective first crease lines, so that opposite first and second lateral container walls are formed, wherein the corner flaps of the first and second lateral panels are folded at 90° about the respective lengths of the second and third crease lines, wherein the third and fourth lateral panels are folded at 90° about the respective lengths of the second and third crease lines, so that the third and fourth lateral panels are arranged parallel and externally to the flaps of the first and second lateral panels, forming a pair of opposite third and fourth lateral container walls, wherein said at least one of said first portion and second portion protrudes vertically beyond said top edge of at least one of said lateral panels and corner flaps opposite to said bottom panel, and wherein said protruding area is facing outwards . According to the invention, by changing size and marginal features of the blank, it is possible to produce different trays satisfying quite different requirements. According to the present invention, the performance of the cardboard or cartonboard used is optimized by using strengthening members where they are most needed and thus lightening the general structure of the container, which is thus fundamentally different from the conventional one due to the significant increase in performance. The strength-conferring material is allocated only where it is needed, so that the quantity of fiber is dramatically lower in comparison with conventional chassis. Such a reduction is rendered possible by the use of the compression members which confer the required strength. According to the prior art, the final container is produced from a blank or chassis, in the entirety of which the quantity of fiber and the board grade are adapted to the performances required for the intended application. On the contrary, according to the present invention, the manufacturing of chassis of different board grades is avoided and the chassis can be produced with the lightest weight, whereas the satisfaction of different requirements is allowed by selection of the proper size and material grade of the compression members. The gist of the present invention thus resides in the presence of the compression members, whose size can vary and provide the flexibility necessary for adapting to the different requirements with the lowest possible weight obtainable today on a corrugator. Furthermore, the compression member and, particularly, its protruding area can be profiled and printed bespoke to requirements of customers and messages they wish to communicate to shoppers. Moreover, it prevents the need to print bespoke artwork for new promotions / cross promotions / price point changes, and allows efficacy of different promotional messaging to be tested on same stock keeping unit.

A blank (see figures 1 to 3) comprises a chassis 10 of corrugated cardboard or cartonboard and a compression member 30 of corrugated cardboard or cartonboard. The cardboard or cartonboard of the compression member 30 can be of the same or different kind as the cardboard or cartonboard of the chassis 10. The flutes of the cardboard of the compression member 30 may be substantially orthogonal or parallel to the flutes of the cardboard of the chassis 10. The chassis 10 has a series of two first parallel crease lines 12a-b, and a second and a third crease line 14a, 14b intersecting the two first parallel crease lines 12a-b. The first, second and third crease lines 12a-b, 14a, 14b define a series of a quadrangular first lateral panel 16, a quadrangular bottom panel 18 and a quadrangular second lateral panel 20. As used herein, terms as "bottom", "back", "front", "top" and the like refer to the display configuration of the box which will be illustrated in the following with reference to figure 3. Furthermore, the second crease line 14a defines a first corner flap 21, a short third lateral panel 22 and a second corner flap 23 connected to the first lateral panel 16, bottom panel 18 and second lateral panel 20, respectively. The third crease line 14b defines a third corner flap 25, a fourth lateral panel 26 and a fourth corner flap 27 connected to the first lateral panel 16, bottom panel 18 and second lateral panel 20, respectively. The second and third crease lines 14a, 14b are orthogonal to the two first parallel crease lines 12a-b and parallel to each other, so that the panels 16, 18 and 20 are substantially rectangular, including the particular case of "square". As used herein, the third lateral panel 22 is designated as "short" in that it is, or comprises at least a portion, shorter than the other lateral panels 16, 20, 26, as can be seen in the erected configuration of the container, shown in figure 3. The compression member 30 has a fourth crease line 30a defining a first portion 31 and a second portion 32 in the compression member 30. As shown in figure 2, the compression member 30 is glued to an internal face of the chassis 10. More specifically, the second portion 32 of the compression member 30 is glued to an internal face of the second lateral panel 20, and / or the first portion 31 of the compression member 30 is glued to an internal face of the second corner flap 23. The second portion 32 of the compression member 30 is contiguous and parallel to the internal face of the second lateral panel 20, and the first portion 31 of the compression member 30 is contiguous and parallel to the internal face of the second corner flap 23. The fourth crease line 30a is, therefore, contiguous and parallel to the length of the second crease line 14a between the second lateral panel 20 and the second corner flap 23. The first portion 31 of the compression member 30 protrudes beyond a top edge 23a of the second corner flap 23, opposite to the bottom panel 18, and, therefore, comprises a protruding area 31a (shown in figure 3) configured to bear graphic or text elements (not shown). A container C, in particular a tray (see figure 3), is obtained from the previously disclosed blank by substantially conventional automatized methods of folding, possibly providing also for using, if necessary, glue and / or adhesive tape. In particular, one of such methods provides for: folding the first lateral panel 16 at 90° about the respective first crease line 12a, so that a first lateral container wall is formed, - folding the second lateral panel 20 with the compression member 30 at 90° about the respective first crease line 12b, so that a second lateral container wall is formed, opposite to the first lateral container wall, - folding the corner flaps 21, 25, 23, 27 of the first and second lateral panels 16, 20 at 90° about the respective lengths of the second and third crease lines 14a, 14b, - folding the third and fourth lateral panels 22, 26 about the respective lengths of the second and third crease lines 14a, 14b, so that the third and fourth lateral panels 22, 26 are arranged parallel and externally to the flaps 21, 23, 25, 27 of the first and second lateral panels 16, 20, forming a pair of opposite third and fourth lateral container walls. The corner area between the second lateral container wall (formed by the second lateral panel 20) and the third lateral container wall (formed by the third lateral panel 22 and second corner flap 23) is reinforced by the compression member 30. The bottom edges of the compression member 30, formed by the bottom edge 31b of the first portion 31 and the bottom edge 32b of the second portion 32, rest on the bottom panel 18. Furthermore, the first portion 31 protrudes vertically beyond the top edge 23a of the second corner flap 23 and a top edge 22a of the third lateral panel 22. Therefore, the outward facing, protruding area 31a of the first portion 31 of the compression member 30 is exposed to sight, exposing the graphic or text elements borne by it. Figures 4 and 5 illustrate a second embodiment of blank and container, respectively, wherein features equal or equivalent to the ones disclosed with reference to the embodiment of the previous figures have the same reference number. The chassis 10 of figures 4-5 differs from the embodiment of figures 1-3 in that the lateral panels 16, 20, 22, 26 have substantially the same height dimension, and in that a different compression member 30 is provided. The compression member 30 has a fourth crease line 30a defining a first portion 31 and a second portion 32 in the compression member 30.

The second portion 32 of the compression member 30 is contiguous and parallel to the internal face of the bottom panel 18, and the first portion 31 of the compression member 30 is contiguous and parallel to the internal face of the fourth lateral panel 26. The fourth crease line 30a is, therefore, contiguous and parallel to the length of the third crease line 14b between the bottom panel 18 and the fourth lateral panel 26. Furthermore, the compression member is contiguous to second lateral wall 20. The first portion 31 of the compression member 30 protrudes beyond a top edge 26a of the fourth lateral panel 26, opposite to the bottom panel 18, and, therefore, comprises a protruding area 31a (shown in figure 5) configured to bear graphic or text elements (not shown) A container C, in particular a tray (see figure 5), is obtained from the above disclosed blank by a method as previously disclosed. The corner area between the bottom panel 18 and the fourth lateral panel 26, as well as the corner area between the second lateral container wall (formed by the second lateral panel 20) and the fourth lateral container wall (formed by the fourth lateral panel 26 and fourth corner flap 27) is reinforced by the compression member 30. Furthermore, the first portion 31 protrudes vertically beyond the top edge 26a of the fourth lateral panel 26.

The second portion 32 of the compression member 30 is contiguous and parallel to the internal face of the second lateral panel 20, and the first portion 31 of the compression member 30 is contiguous and parallel to the internal face of the second corner flap 23. The fourth crease line 30a is, therefore, contiguous and parallel to the length of the second crease line 14a between the second lateral panel 20 and the second corner flap 23. The first portion 31 of the compression member 30 protrudes beyond a top edge 23a of the second corner flap 23, opposite to the bottom panel 18. The second portion 32 of the compression member 30 protrudes beyond a top edge 20a of the second lateral panel 20, opposite to the bottom panel 18. Therefore, the first portion 31 and second portion 32 comprises respective protruding areas 31a, 32a (shown in figure 7) configured to bear graphic or text elements (not shown). A container C, in particular a tray (see figure 7), is obtained from the above disclosed blank by a method as previously disclosed. The corner area between the second lateral container wall (formed by the second lateral panel 20) and the third lateral container wall (formed by the third lateral panel 22 and second corner flap 23) is reinforced by the compression member 30.

More specifically, the second portion 52 of the compression member 50 is glued to an internal face of the first lateral panel 16, and / or the first portion 31 of the compression member 30 is glued to an internal face of the first corner flap 21. The second portion 52 of the compression member 50 is contiguous and parallel to the internal face of the first lateral panel 16, and the first portion 31 of the compression member 30 is contiguous and parallel to the internal face of the first corner flap 21. The fourth crease line 50a is, therefore, contiguous and parallel to the length of the second crease line 14a between the first lateral panel 16 and the first corner flap 21. The first portion 51 of the further compression member 50 protrudes beyond a top edge 21a of the first corner flap 21, opposite to the bottom panel 18, and, therefore, comprises a protruding area 51a (shown in figure 9) configured to bear graphic or text elements (not shown). In the container of figure 9, the corner area between the first lateral container wall (formed by the first lateral panel 16) and the third lateral container wall (formed by the third lateral panel 22 and first corner flap 21) is reinforced by the further compression member 50. Furthermore, the first portion 51 protrudes vertically beyond the top edge 21a of the first corner flap 21 and the top edge 22a of the third lateral panel 22. Therefore, the outward facing, protruding area 51a, of the first portion 51 of the compression member 50 is exposed to sight, exposing the graphic or text elements borne by it. Figures 10 and 11 illustrate a fifth embodiment of blank and container, respectively, wherein features equal or equivalent to the ones disclosed with reference to the embodiment of the previous figures have the same reference number. Figures 12 and 13 illustrate a sixth embodiment of blank and container, respectively, wherein features equal or equivalent to the ones disclosed with reference to the embodiment of the previous figures have the same reference number. The chassis 10 and the compression member 30 of figures 10-11 and figures 12-13 are substantially identical to the embodiment of figures 4-5, with a different profile and different placement of the compression member 30. Figures 14 and 15 illustrate a seventh embodiment of blank and container, respectively, wherein features equal or equivalent to the ones disclosed with reference to the embodiment of the previous figures have the same reference number. A blank (see figure 14) comprises a chassis 10 of corrugated cardboard or cartonboard, a first compression member 30 of corrugated cardboard or cartonboard and a plurality of second compression members 60 of corrugated cardboard or cartonboard.

The second and third crease lines 14a, 14b are orthogonal to the two first parallel crease lines 12a-b and parallel to each other, so that the panels 16, 18, 20 and 71 are substantially rectangular, including the particular case of "square". A perforated or notched detachment line 20c is formed transverse to the second lateral panel 20 and between the top panel 71 and the top flaps 72, 73, 74. This perforated or notched detachment line 20c defines, in the second lateral panel 20, a preferably U-shaped bottom portion 20a and a top portion 20b separated by the perforated or notched detachment line 34c. At least one aperture 20d is formed adjacent to the perforated or notched detachment line 20c, in order to facilitate handling. The first compression member 30 has a fourth crease line 30a defining a first portion 31 and a second portion 32 in the compression member 30. As shown in figure 14, the first compression member 30 is glued to an internal face of the chassis 10. More specifically, the first portion 31 of the compression member 30 is glued to an internal face of the second corner flap 23, and / or the second portion 32 of the compression member 30 is glued to an internal face of the second lateral panel 20. The first portion 31 of the compression member 30 is contiguous and parallel to the internal face of the second corner flap 23, and the second portion 32 of the compression member 30 is contiguous and parallel to the internal face of the second lateral panel 20. The fourth crease line 30a is, therefore, contiguous and parallel to the length of the second crease line 14a between the second lateral panel 20 and the second corner flap 23. The second portion 32 of the compression member 30 protrudes beyond a top edge of the bottom portion 20a of the second lateral panel 20, opposite to the bottom panel 18, and, therefore, comprises a protruding area 32a (shown in figure 16) configured to bear graphic or text elements (not shown). Each of the second compression members 60 has a respective fourth crease line 60a defining a first portion 61 and a second portion 62 in the second compression member 60. The second compression members 60 are shaped differently from the first compression member 30 and do not have the above mentioned protruding area. As shown in figure 14, the second compression members 60 are glued to an internal face of the chassis 10. More specifically, the second portions 62 of the second compression members 60 are glued to an internal face of the first, third and fourth corner flaps 21, 25, 27, respectively, and / or the first portions 61 of the second compression members 60 are glued to an internal face of the first lateral panel 16 and second lateral panel 20.

A container C, in particular a box (see figure 16), is obtained from the previously disclosed blank by substantially conventional automatized methods of folding, possibly providing also for using, if necessary, glue and / or adhesive tape. In particular, one of such methods provides for: - folding the first lateral panel 16 with the respective second compression members 60 at 90° about the respective first crease line 12a, so that a first lateral container wall is formed, folding the second lateral panel 20 with the first compression member 30 and respective second compression member 60 at 90° about the respective first crease line 12b, so that a second lateral container wall is formed, opposite to the first lateral container wall, - folding the corner flaps 21, 25, 23, 27 of the first and second lateral panels 16, 20 at 90° about the respective lengths of the second and third crease lines 14a, 14b, - folding the third and fourth lateral panels 22, 26 about the respective lengths of the second and third crease lines 14a, 14b, so that the third and fourth lateral panels 22, 26 are arranged parallel and externally to the flaps 21, 23, 25, 27 of the first and second lateral panels 16, 20, forming a pair of opposite third and fourth lateral container walls, - folding the top panel 71 at 90° about the respective first crease line 12c, - folding the first top flap 72 at 90° about the respective first crease line 12d, so that the first top flap 72 is arranged parallel and externally to the first lateral panel 16, - folding the second and third top flaps 73, 74 at 90° about the respective lengths of the second and third crease lines 14a, 14b, so that the second and third top flaps 73, 74 are arranged parallel and externally to the flaps 21, 23, 25, 27 of the first and second lateral panels 16, 20. The corner areas between the lateral container walls are reinforced by the compression members 30, 60. The bottom edges of the compression members 30, 60 rest on the bottom panel 18. Furthermore, the second portion 32 of the first compression member 30 protrudes vertically beyond the top edge of the bottom portion 20a of the second lateral panel 20. A tearing action can be exerted on the top part of the box C by gripping on the aperture 20d formed in the second lateral panel 20. Consequently, a removable portion L of the box C, formed by the top portion 36a of the second lateral panel 20 and the top panel 71 gets detached from the bottom portion 20a of the second lateral panel 20 and from the top flaps 72, 73, 74 as a result of the laceration of the perforated or notched detachment line 20c, while the bottom portion 20a of the second lateral panel 20 and the top flaps 72, 73, 74 remain attached to the box C. Therefore, the box C splits into two parts, a tray T and a removable portion L, as a result of the complete laceration of the perforated or notched detachment line 20c (figure 16). Therefore, the outward facing, protruding area 32a of the second portion 32 of the first compression member 30 is exposed to sight, exposing the graphic or text elements borne by it. Figures 17-19 illustrate an eigth embodiment of blank and container, respectively, wherein features equal or equivalent to the ones disclosed with reference to the embodiment of the previous figures have the same reference number.
