Description

[0001] DESCRIPTION

[0003] Folding box comprising a cardboard tray

[0005] The invention relates to a folding box comprising a cardboard tray.

[0007] Rigid cardboard boxes are used for packaging cosmetics, perfumes, books, CDs, cutlery, mobile phones, and other valuables or gifts. These boxes are made of extra-thick cardboard, covered with printed paper or another coating material. Rigid cardboard boxes are especially common for Christmas, Easter, Valentine's Day, Mother's Day, Father's Day, and other holiday products. They must be hand-assembled and delivered by the packaging manufacturer to the product manufacturer. The manufacturing and transport of these rigid boxes from the packaging manufacturer to the product manufacturer are complex and costly processes.

[0009] EP 2072408 B1 describes a tray made from a single piece of die-cut cardboard, in which a back wall is joined at its side edges to outer side wall parts by means of fold lines, which are joined at their upper edges to inner side wall parts also by means of fold lines, the latter being folded against the outer side wall parts, and an inner side wall part is joined at its lower edge, by means of a fold line, to an additional wall that rests on the back wall.

[0011] CN 103387075 A describes a collapsible box in which a reinforcing plate is folded, by means of connecting plates, to a bottom plate of a tray-shaped lower part. This reinforces the collapsible box.

[0012] US 2007/235513 A1 describes a folding box with a rectangular bottom wall, outer side wall parts, corner flaps and inner side wall parts, as well as with a cardboard insert disposed inside the bottom wall, wherein the fiber direction of the cardboard insert is oriented at an angle of 90° to the fiber direction of the cardboard bottom wall of the tray.

[0014] Based on this, the invention aims to provide a foldable box that offers even greater strength and stability, and requires less material.

[0016] This objective is achieved by means of a folding box with the features of claim 1. Advantageous embodiments of the folding box are described in the dependent claims.

[0018] The folding box according to the invention comprises a cardboard tray including a rectangular back wall, outer side wall portions joined by fold lines to the edges of said back wall, corner flaps joined by side fold lines to the side edges of the outer side wall portions, and inner side wall portions joined by fold lines to the upper edges of the outer side wall portions. The corner flaps are folded against an adjacent outer side wall portion, and the inner side wall portions are folded against the inner faces of the outer side wall portions and against the corner flaps adjacent thereto. The box also comprises a cardboard insert disposed on the inner face of the back wall, the fiber direction of the cardboard insert being oriented at an angle to the fiber direction of the cardboard back wall of the tray, preferably at an angle of 90°. It is characterized by the fact that the inner side wall parts of the tray are joined at their lower edge, by means of fold lines, to bottom tabs that rest on the inner face of the bottom wall or insert, and that said bottom tabs have bevels on their side edges, with adjacent bottom tabs resting against each other with said bevels.

[0020] According to the invention, a particularly robust folding box is obtained by using a so-called "Krempel-Tray" as a tray, in which the side walls are formed by a double layer. Furthermore, corner flaps provide reinforcement at the corners of the tray and stabilize it in an upright position. Finally, the bottom of the tray is particularly robust, as it is formed by the bottom wall and a cardboard insert arranged on the inner face of that wall. The strength of the bottom clearly exceeds that of a conventional tray manufactured from a single die-cut piece with a double-layer bottom according to EP 2072408 B1, since the reinforcement consists of a cardboard insert whose orientation with respect to the bottom wall is determined such that the fiber direction of the cardboard insert is perpendicular or at another angle to the fiber direction of the cardboard of the bottom wall. The fiber direction corresponds to the direction in which, due to inherent manufacturing processes, the cellulose fibers are preferentially aligned in the cardboard. Surprisingly, it has been found that the stability of the tray bottom can be significantly improved when the fiber direction of the tray bottom wall is oriented at an angle to the fiber direction of the insert. Furthermore, the folding box offers the advantage of being able to be stored and transported in flat stacks, considerably reducing the effort required for storage and transport compared to conventional rigid boxes. In particular, stacked tray cutouts can be stored and transported in a space-saving manner. Another advantage is that the folding box can be erected without glue and remains stable in its assembled configuration. This is achieved because the corner flaps are secured between the inner and outer side wall pieces, and because the inner side wall pieces rest against each other and against the bottom wall or insert. Another advantage is that the folding box can be manufactured from high-quality, printable cardboard, so its appearance, in terms of printing, closely resembles that of a rigid cardboard box. The inner surface of the folding box also offers excellent printability. Finally, considerable weight savings can be achieved compared to a rigid cardboard box.

[0022] According to one embodiment, the folding box comprises a lid with a lid wall intended to cover the tray. According to another embodiment, the lid is made of cardboard. According to another variant, the tray is inserted into an outer packaging or closed at the top by a transparent cardboard sheet, which, for example, is sealed over the upper edge of the tray.

[0024] According to another embodiment, an additional cardboard insert is placed on the inner face of the lid wall, the fiber direction of which is oriented at an angle to the fiber direction of the lid wall cardboard, preferably at an angle of 90°. This results in a particularly stable lid wall, which contributes to the overall strength of the folding box. However, the invention also contemplates possible variations in which an additional cardboard insert is not placed on the inner face of the lid wall, for example, when the folding box has a transparent lid.

[0026] According to another embodiment, the insert and the bottom wall are bonded together with glue or another adhesive, or the additional insert and the lid wall are bonded together with glue or another adhesive. This bonding of materials results in a particularly rigid and stable bottom or lid. The attachment of the insert to the bottom wall or the additional insert to the lid wall is preferably carried out at the folding carton manufacturer's premises. The pre-glued cutouts can be stored flat in stacks and delivered by the folding carton manufacturer to the manufacturer of the product to be packaged or to a co-packer (custom packer). The co-packer then simply assembles the folding carton in the conventional manner. Alternatively, the bottom wall and the insert, or the lid wall and the additional insert, are not glued by the folding carton manufacturer but are delivered separately, flat in stacks, to the manufacturer of the product to be packaged or to the co-packer, who assembles the carton from the supplied cutouts. The insert can be placed loose on the back wall or glued to it, or the additional insert can be placed loose on the top wall or glued to it.

[0028] According to another embodiment, the insert and the back wall are bonded together by several parallel lines of glue or strips of other adhesive, and/or the additional insert and the lid wall are bonded together by several additional parallel lines of glue or strips of other adhesive. The parallel lines of glue or strips of other adhesive significantly increase stability or rigidity. Full-surface bonding between the insert and the back wall or between the additional insert and the lid wall is not required. Applying lines or strips of adhesive allows for considerable savings in adhesive compared to full bonding.

[0030] According to another embodiment, three adhesive strips are provided, with one or more central strips positioned between two outer strips. In this way, the insert is bonded to the back wall or the lid wall, preventing the different layers from separating or sliding against each other.

[0032] According to another embodiment, the strips are applied parallel to the direction of the board from which the folding box is formed or to the direction of the board from which the lid is formed. This allows for high production speeds.

[0034] According to another embodiment, the folding box has a band-type lid. The side walls of the band-type lid, positioned over the tray, further increase the stability of the side walls of the folding box. According to another embodiment, an additional insert is provided on the inner face of the lid wall of the band-type lid, increasing the stability of said wall.

[0036] According to another embodiment, no additional insert is provided on the inner face of the lid wall of the band-type lid, for example, when the band-type lid is configured as a transparent lid.

[0038] According to another embodiment, the lid comprises a rectangular lid wall, additional outer side wall portions joined by fold lines to the edges of the lid wall, additional corner flaps joined by side fold lines to the additional outer side wall portions, and additional inner side wall portions joined by fold lines to the lower edges of the additional outer side wall portions. The additional corner flaps are folded against an adjacent additional outer side wall portion, and the additional inner side wall portions are folded against the inner faces of the additional outer side wall portions and against the additional corner flaps adjacent to them. In this way, a band-like lid is formed which, like the tray of the folding box, is configured as a "Krempel-Tray," which can be stored and transported flat in stacks and assembled without gluing into a stable configuration.

[0040] In one embodiment, triangular tabs are connected by side fold lines to the side edges of the outer side wall parts. These triangular tabs are joined in pairs by a central fold line between the side fold lines, and each pair of triangular tabs is folded against each other around the central fold line and against one of the adjacent outer side wall parts. In this embodiment, each corner flap is formed by a pair of triangular tabs. This provides a secure and particularly stable connection between the adjacent outer side wall parts. According to another embodiment, additional triangular tabs are connected to the additional outer side wall parts by means of side fold lines. These triangular tabs are also joined in pairs by a central fold line between the side fold lines, and each pair of additional triangular tabs is folded against each other around the central fold line and against an adjacent additional outer side wall part. In this embodiment, each additional corner flap is formed by a pair of additional triangular tabs. This provides a secure and particularly stable connection between adjacent additional outer side wall parts at the corners.

[0042] According to another embodiment, the inner side wall parts cover the insert at the edges, or additional inner side wall parts cover the additional insert at the edges. In this way, the insert or the additional insert is supported laterally by the inner side wall parts or the additional inner side wall parts, providing particularly high stability of the folding box between the side walls and the bottom wall or the lid wall. If the insert or the additional insert is not glued, this configuration prevents the insert from coming out of the box and/or the additional insert from coming out of the flap lid. For this purpose, the inner side wall parts preferably cover the insert at least on two opposite edges, or the additional inner side wall parts cover the additional insert at least two opposite edges.

[0044] According to another embodiment, the additional inner side wall portions are joined at their upper edges, by means of fold lines, to lid tabs that bear against the inner face of the lid wall or the additional insert. The inner side wall portions may be better supported by the bottom tabs, or the additional inner side wall portions may be better supported by the lid tabs, in order to maintain the tray or sash-type lid in its assembled configuration. The lid tabs have additional bevels on their side edges, and adjacent lid tabs bear against each other by means of these additional bevels.

[0046] According to another embodiment, the tray or lid is configured according to ECMA code B 10.02.00.00 or B 10.04.00.00.

[0048] According to another embodiment, the lid is a sleeve. The sleeve comprises, or is formed by, four sleeve walls joined together by fold lines. One of the sleeve walls also constitutes the lid wall. One of the sleeve walls may be formed by two overlapping sleeve wall sections joined or hooked together at the overlap. The tray can be inserted into the sleeve through one of two openings located at its ends. The sleeve may be made entirely of cardboard or a combination of cardboard and transparent plastic, with the lid wall being at least partially made of transparent plastic to form a lid with a window. Alternatively, the sleeve may be made entirely of transparent plastic.

[0050] According to another embodiment, the lid is a hinged lid. The hinged lid may be formed as a single piece with the tray or constitute an additional component. In the case of a one-piece configuration, the hinged lid may be joined at one of its edges by a fold line to a connecting tab, which is joined by another fold line to the lower edge of an inner side wall portion. In a multi-piece design, the hinged lid may be joined at one of its edges by a fold line to a connecting tab, which, in turn, is joined at its lower edge to an insert tab that may be anchored between an inner side wall portion and an outer side wall portion.

[0052] According to another embodiment, the insert has a plurality of parallel scoring lines, or the additional insert has a plurality of additional parallel scoring lines. The scoring lines or the additional scoring lines further increase the stability of the folding box. According to another embodiment, the scoring lines of the insert are arranged parallel to or at an angle, preferably 90°, with respect to the grain direction of the insert's cardboard, or the scoring lines of the additional insert are arranged parallel to or at an angle, preferably 90°, with respect to the grain direction of the additional insert's cardboard.

[0054] According to another embodiment, the tray cardboard has a linear embossing at least on its visible outer surface, and the insert cardboard has a linear embossing at least on its top surface, or the lid cardboard has a linear embossing at least on its visible outer surface, or the additional insert cardboard has a linear embossing at least on its underside. In this way, the tray or lid has a linear embossing on the surfaces visible to the user when the folding box is closed or open. This gives the folding box a particularly high-quality appearance. To this end, the folding box, according to another embodiment, is printed on these same surfaces. The printing on the embossed surface of the folding box is of particularly high quality. To further enhance the print quality, the corresponding surfaces of the folding box have embossing performed in the same manner, i.e., with the same type, number, and weight of the embossing layer.

[0055] According to another embodiment, the tray has scoring lines on at least one wall, or the lid has additional scoring lines on at least one of its walls. This contributes to greater stability of the folding box.

[0057] According to another embodiment, the tray and the lid are formed from a single cutout or from different cutouts.

[0058] According to another embodiment, the tray and the insert are formed from separate cutouts. According to another embodiment, the lid and the additional insert are formed from separate cutouts.

[0060] According to another embodiment, the tray and the insert are made of cardboard with the same or different grammage. According to another embodiment, the lid and the additional insert are made of cardboard with the same or different grammage.

[0062] According to another embodiment, an inner element is inserted into the tray, which has at least one recess for inserting a product. According to another embodiment, said inner element is made of cardboard. According to another embodiment, the inner element has a horizontal upper wall with at least one cutout for receiving and laterally supporting a product, or it has at least one vertical wall with at least one other cutout on the upper edge for supporting and perimeterly holding a product inserted into said cutout.

[0063] According to another embodiment, the inner element has, at least on the side visible to the user when the folding box is open, a linear embossing. According to another embodiment, this embossing has an impression. According to another embodiment, the embossing of the inner element is carried out in the same way as the embossing of the tray.

[0065] According to another embodiment, all parts of the folding box have an embossing made in the same way.

[0066] The invention is explained in more detail below with reference to the accompanying drawings relating to an exemplary embodiment. The drawings show:

[0093] Fig. 2 shows a second cutout 19 for an insert 20, which has a rectangular shape whose dimensions are adapted to the dimensions of the back wall 2.

[0095] To assemble the folding box, insert 20 is placed on the bottom wall 2 of cutout 1, and the outer side wall parts 3.1, 4.1, 5.1, and 6.1 are folded upwards. Insert 20 is sized to fit precisely between the outer side wall parts once erected. It is positioned on the bottom wall 2 so that the FL2 fiber direction of insert 20 is perpendicular to the FL1 fiber direction of the bottom wall 2.

[0097] When lifting the outer side wall parts 3.1, 4.1, 5.1, 6.1, the adjacent triangular tabs 15.1 and 15.2, 16.1 and 16.2, 17.1 and 17.2, 18.1 and 18.2 fold against each other along the center fold line and against the inside face of one of the outer side wall parts 3.1, 4.1, 5.1, 6.1. Finally, the inner side wall parts 3.2, 4.2, 5.2, and 6.2 fold against the inner faces of the outer side wall parts 3.1, 4.1, 5.1, and 6.1 and against the adjacent triangular tabs 15.1 and 15.2, 16.1 and 16.2, 17.1 and 17.2, and 18.1 and 18.2, while the bottom tabs 7, 8, 9, and 10 fold over the top face of insert 20. This forms a tray 22 that is stable in its assembled position, as the inner side wall parts 3.2, 4.2, 5.2, and 6.2 support each other along their side edges, and the bottom tabs 7, 8, 9, and 10 rest on insert 20 and against each other. through bezels 11.1 to 14.2.

[0099] Tray 22 mounted with insert 20 is shown in Fig. 5.

[0101] According to Fig. 3, a third cutout 23 for a lid 24 comprises a rectangular lid wall 25, which is joined at its side edges by fold lines to additional external side wall parts 26.1, 27.1, 28.1, 29.1. The other outer side wall parts 26.1, 27.1, 28.1, 29.1 are joined at their upper edges by fold lines to other inner side wall parts 26.2, 27.2, 28.2, 29.2, to together form side walls 26, 27, 28, 29. The other inner side wall parts 26.2, 27.2, 28.2, 29.2 are in turn joined at their lower edges by fold lines to lid tabs 30, 31, 32, 33, which have bevels inclined at 45° on their side edges, identified as 34.1, 34.2, 35.1, 35.2, 36.1, 36.2, 37.1, 37.2.

[0103] By means of side fold lines, additional triangular tabs 38.1, 38.2, 39.1, 39.2, 40.1, 40.2, 41.1, 41.2 are connected to the side edges of the outer side wall parts, each pair of additional triangular tabs 38.1 and 38.2, 39.1 and 39.2, 40.1 and 40.2, 41.1 and 41.2 being joined together by a central fold line located between the side fold lines.

[0105] Fig. 2 shows a fourth cutout 42 for an additional insert 43, which has a rectangular shape whose dimensions are adapted to the dimensions of the lid wall 25.

[0107] To assemble the lid 24, the additional insert 43 is placed over the lid wall 25 of the third cutout 23, and the additional outer side wall parts 26.1, 27.1, 28.1, 29.1 are folded upward. The additional insert 43 is sized so that it fits precisely between the additional outer side wall parts once erected. It is positioned over the lid wall 25 so that the FL4 fiber direction of the additional insert 43 is oriented perpendicular to the FL3 fiber direction of the lid wall 25.

[0109] When lifting the additional external side wall parts 26.1,27.1,28.1,29.1, the additional adjacent triangular tabs 38.1 and 38.2, 39.1 and 39.2, 40.1 and 40.2, 41.1 and 41.2 fold against each other along the center fold line and against the inside face of one of the additional external side wall parts 26.1, 27.1, 28.1, 29.1. Finally, the additional inner side wall parts 26.2, 27.2, 28.2, 29.2 fold against the inner faces of the additional outer side wall parts and against the adjacent triangular tabs 38.1 and 38.2, 39.1 and 39.2, 40.1 and 40.2, 41.1 and 41.2, while the lid tabs 30, 31, 32, 33 fold over the top face of the additional insert 43.

[0111] This forms a band-type cover 44. This configuration is stable in the mounted position, as the additional inner side wall parts 26.2, 27.2, 28.2, 29.2 support each other by their side edges, and the cover tabs 30, 31, 32, 33 rest on the inner face of the additional insert 43 and on each other through the additional bevels 34.1 to 37.2. The mounted band-type cover 44 is shown in Fig. 5.

[0113] According to Fig. 5, an inner cardboard element 45 has been inserted into tray 22.
