TRAY OR SIMILAR CONTAINER MADE OF SHEET MATERIAL

Description

Field of the invention

[0001] The present invention relates to a tray or similar container comprising a sheet or panel, folded and glued, which defines, in a configuration of use:

• a base;
• a plurality of walls around said base, connected to said base via a first set of folding lines; and
• at least one partition that runs through said base starting from a first wall of said plurality of walls, or a region in the proximity of said first wall, up to a second wall of said plurality of walls opposite to said first wall, or a region in the proximity of said second wall,

wherein said panel has a second set of folding lines arranged parallel to one another in a direction transverse to said first and second walls and configured for identifying at least one first strip and one second strip of said panel that are adjacent to one another, and at least one third strip and one fourth strip, which are connected to said first and second strips, respectively, and
wherein, in said configuration of use, said first and second strips are raised with respect to said third and fourth strips so that said first and second strips form said partition and said third and fourth strips form said base or parts thereof, and which tray or similar container also has the remaining features of the preamble of claim 1.

General technical problem

[0002] A tray of the type referred to above is, for example, described in the U.S. patent No. US3876132. These trays are characterized in that they are provided with one or more dividers or partitions designed to identify a series of compartments via which it is possible to order a series of products, objects, on the tray. These trays may, for example, constitute proper packages on which the products are arranged according to an appropriate display mode.

[0003] Usually, the trays of the type in question are delivered to the sites in which they will be filled with the products (for example, the production plant or else the centre for sale of the products), in the condition where they are already folded and glued to enable their immediate use. This circumstance poses, however, the problem of reducing as much as possible the encumbrance of the trays when they are stacked on top of one another in order to be able to store the largest number possible of them within a single box. The U.S. patent No. US3876132 referred to above attempts to solve this problem by making the walls of the trays inclined with respect to one another in a way converging towards their base so as to be able to nest them into one another, in a condition of reduced encumbrance. EP0302563A1 discloses a partitioned collapsible tray according to the preamble of Claim 1.

Object and summary of the invention

[0004] The object of the present invention is to solve the problem mentioned above in an even more effective way, via a tray having the characteristics recalled in Claim 1.

[0005] As will be seen in detail in what follows, the tray described herein, already folded and glued, can, in fact, be set in a flattened condition of minimal encumbrance.

[0006] The claims form an integral part of the technical teaching provided herein in relation to the invention.

Detailed description of the invention

[0008] In the ensuing description various specific details are illustrated aimed at providing an in-depth understanding of the embodiments. The embodiments may be provided without one or more of the specific details, or with other methods, components, or materials, etc. In other cases, known structures, materials, or operations are not illustrated or described in detail so that various aspects of the embodiment will not be obscured.

[0009] The references used herein are only provided for convenience and hence do not define the sphere of protection or the scope of the embodiments.

[0010] With reference to Figures 9 and 10, designated by the reference number 10 is a tray made of a sheet material, for example a sheet of dinked cardboard or paperboard.

[0011] The tray 10 comprises a sheet or panel 1 as shown in figure 1, folded and glued so as to define, in the configuration of use of the tray, illustrated in Figure 9, a base 2, a series of walls or sides 4, 6, 8, 12, and two dividers or partitions 14, 16, which are carried by the base 2 and extend from a region in the proximity of the wall 12 up to a region in the proximity of the opposite wall 6.

[0012] Figure 1 illustrates the sheet 1 in a condition of complete plane development thereof. In various embodiments, as in the one illustrated, the sheet 1 has a central region, preferably rectangular in shape, which, in the configuration of use of the tray, comes to define the base 2 and the partitions 14 and 16.

[0013] The walls 4, 6, 8, 12 are rotatably connected to the central region via a first set of folding lines, in particular the folding lines 51, 53, 55, 57.

[0014] The walls 12 and 6 have respective foldable tabs 12', 6', via which the walls 12 and 6 are glued to the walls 8 and 4. The points of gluing are designated by the letters A, B, C, D, which repeat for the pairs of points that are brought into contact with one another during assembly of the tray.

[0015] Assembly of the tray 10 simply involves folding the walls 4, 6, 8, and 12 and gluing together the corresponding points A, B, C, D.

[0016] In the aforesaid central region, the sheet 1 has a second set of folding lines, in particular the folding lines 61, 63, 65, 67, 69, 71, which are arranged parallel to one another in a direction transverse to the walls 12, 6, and identify the strips 18, 22, 24, 26, 28, 32, 34. As may be seen in Figure 10, in the configuration of use of the tray, the strips 22, 24 and the strips 28, 32 are raised with respect to the strips 18, 26, 34 according to a substantially vertical orientation, in which are in contact with one another two by two, defining the two partitions 16 and 14, respectively. In this condition, the strips 18, 26, 34 instead define, as a whole, the base 2; in this connection, it should be noted that the sum of the respective widths of the strips 18, 26 and 34 corresponds substantially to the extension of the base in the direction transverse to the partitions 14 and 16.

[0017] In preferred embodiments, as in the one illustrated, one or more sheets 11 may be associated to the tray 10, one of which, illustrated in Figure 2, is to be mounted on the partitions 14 and 16, oriented in a direction transverse to these, to form a further partition of the tray, transverse to the partitions 14 and 16. In various embodiments, as in the one illustrated, the sheet 11 is folded on itself along a folding line 11', which divides it in a symmetrical way. Preferably, the partitions 14 and 16 and/or the sheet 11 have slits 13 designed to enable interpenetration between the partitions 14 and 16 and the sheet 11, so that these form as a whole a sort of grid that divides the base 2 into compartments.

[0018] It should be noted that the sheet 11 constitutes in any case an altogether accessory and non-essential element.

[0019] As mentioned above, the tray described herein, already folded and glued in the way referred to above, it may be set in a flattened configuration of minimal encumbrance. In preferred embodiments, this configuration envisages that the strips forming the partitions of the tray are splayed out in one and the same plane and, at the same time, that the walls of the tray are folded against the series of said strips.

[0020] In order to enable the tray described herein to be set in the flattened condition referred to above, the sheet 1 has a third set of folding lines, in particular the folding lines 73, 75, 77, 79, which traverse the opposite walls 4, 8 in a respective inclined direction such that, by folding the walls 8 and 4 along said lines, there is obtained, at the same time, rotation of all the walls 12, 4, 6, 8 towards the base 2 about the first set of folding lines; moreover, the end edges of the strips 18, 22, 24, 28, 32, 34 are mobile with respect to the opposite walls 12 and 16 so as to enable a relative rotation between the strips in question and said walls. The strip 26 has instead its own end edges connected to the walls 6 and 12 via the folding lines 57 and 53. In various embodiments, as in the one illustrated, the folding lines 73, 75, 77, 79 extend on the respective walls 4 and 8 in directions transverse to the folding lines 55 and 51 and identify the portions A, B, C, D of the walls 4 and 8, which are rotatable with respect to the remaining parts of these walls about the aforesaid folding lines. It may be noted that the portions A, B, C, D correspond to the points of gluing of the walls 4 and 8 to the tabs 12', 6'. Figure 3 illustrates the tray 10 in the flattened configuration. As may be seen in Figure 3, the strips 22, 24, 28, 32 all lie in one and the same plane, the walls 4, 8 and the strips 18, 34 also lie in one and the same plane, in contact with the series of strips 22, 24, 28, 32, and, finally, the walls 6 and 12 are folded against the walls 4 and 8.

[0021] Thanks to the characteristics referred to above, the tray 10 can hence be assembled starting from the sheet 1, by folding and gluing together the walls 4, 6, 8, 12, and can then be stored in the flattened configuration illustrated in Figure 3. At the moment of its use, it can instead be transformed into its configuration of use in a simple and fast way, as described hereinafter with reference to Figures 3 to 9.

[0022] Transformation of the tray 10 from the flattened configuration of Figure 3 to that of use of Figures 9 and 10, envisages the following steps:

• via rotation, raising the walls 12, 4, 6, 8 into a vertical position and at the same time folding the strips 18, 22 and 32, 34 downwards (Figure 4);
• via rotation, raising the strips 18, 22 and 32, 34 towards the internal space delimited by the walls 12, 4, 6, 8 (Figure 5);
• approaching the strips 22, 24 and 28, 32 to one another (Figure 6) and bringing the strips 18 and 34 to the level of the strip 26;
• via rotation, raising the strips 22, 24 32, 34 into their vertical condition to form the partitions 14 and 16 (Figure 7); and
• when envisaged, folding the sheet 11 and inserting it into the slits of the partitions 14 and 16 (Figure 8).

[0023] In alternative embodiments, such as in the one illustrated in Figures 11 and 12 (the reference numbers used in these figures are the same as the ones used in Figures 1 to 10, indicating elements in common with the two solutions illustrated), the tray 10 comprises a single partition 14. In this case, the folding lines of the second set (the lines 61, 63, and 65) are in a number such as to identify four strips, a first one and a second one of which (in the figures just the first strip 22 may be seen) define, in the condition of use of the tray, the aforesaid partition, and the third and fourth strips (the strips 18 and 26) define, instead, the base of the tray. The main characteristics of this embodiment are in any case the same as the ones described above with reference to the embodiment illustrated in Figures 1 to 10. In particular, the sheet of the tray has a third set of folding lines (not visible) of the same type as that referred to above, and the end edges of the first and second strips and of the third strip or (not shown) of the fourth strip, are mobile with respect to the opposite walls 12, 6 of the tray, transverse to said strips, so as to enable a relative rotation of the strips about the folding lines of the second set and with respect to said walls. The remaining strip (the fourth strip or the third strip) has, instead, its own end edges connected to the aforesaid opposite walls, via the corresponding two opposed folding lines of the first set (of which just the line 57 may be seen). As in the other embodiment, in the flattened condition of the tray, the strips forming the partition 14 are splayed out in one and the same plane and, at the same time, the walls 12, 4, 8, 6 of the tray are folded against the series of the strips identified by the second set of folding lines. With reference to Figures 11 and 12, it may be noted that, in this case, to bring the tray from the flattened condition to the condition of use, only the left-hand part of the tray is subjected to the transformation described above for the embodiment of Figures 1-10. In the right-hand part, instead, simply the wall side 4 is turned upwards with respect to the strip 26, about the line 51 of the first set of folding lines.

[0024] Of course, without prejudice to the principle of the invention, the details of construction and the embodiments may vary, even significantly, with respect to what has been illustrated herein purely by way of non-limiting example, without thereby departing from the scope of the invention, as defined by the annexed claims.
