In one embodiment, the octagonal tray includes lace tabs that extend from the aforementioned common upper edges of the first wall panels and their respective reinforcement panels in a direction opposite to the octagonal base panel, and the octagonal base panel has formed lace openings where the lace tabs of another identical octagonal tray are inserted in a stacking situation. Thus, the coupling between the lace tabs and the lace openings provides stability to a column of mutually stacked octagonal trays, whether the octagonal trays are empty or loaded with products.

Preferably, the lace tabs are part of a panel that includes the reinforcement panels and are coplanar with the reinforcement panels, and the lace openings are in adjacent positions and parallel to the first fold lines coinciding with the orthogonal geometric projections of the lace tabs on the octagonal base panel.

In one embodiment, two of the first opposite wall panels, and optionally the first four opposite wall panels two to two, have handle openings sized to allow a manual grip. Preferably, the handle openings are formed in the first wall panels that are provided with reinforcement panels since the grip is convenient to be made in the double thickness reinforced walls.

When the handle openings are formed in the first wall panels that are provided with reinforcement panels, the reinforcement panels may be shorter in a direction perpendicular to the first bending lines than the first wall panels, for example shorter that a distance between the fourth fold lines and an edge of the handle openings closest to the fourth fold lines, in which case the reinforcement panels do not cover the handle openings.

However, in a preferred embodiment, the handle openings are formed in the first wall panels that are provided with reinforcement panels and the reinforcement panels are longer in a direction perpendicular to the first bending lines than a distance between the fourth fold lines and one edge of the handle openings closest to the first fold lines, in which case the reinforcing panels have complementary handle openings that coincide in shape and position with the handle openings of the first panels of wall. In this way, and since the reinforcement panels are superimposed and joined by adhesive to the first wall panels, the octagonal tray has handles formed by the handle openings and

fold lines. These lace openings have a length greater than the distance between the opposite ends of the concave cutting lines and a width greater than the thickness of the sheet of cardboard, corrugated cardboard, plastic, or corrugated plastic from which the die-cut plate is made.

In one embodiment, two of the first opposite wall panels or the four opposite wall panels two to two have handle openings formed, and preferably two

or more of the handle openings are formed in the first wall panels provided with reinforcement panels.

In one embodiment, the reinforcing panels are shorter in a direction perpendicular to the first bending lines than a distance between the fourth bending lines and the handle openings. In another alternative embodiment, the reinforcing panels are longer in a direction perpendicular to the first bending lines than a distance between the fourth bending lines and the handle openings, and the reinforcing panels have complementary handle openings formed. at a distance from the fourth fold lines equal to a distance between the fourth fold lines and said handle openings. The handle openings and the complementary handle openings have the same shapes and dimensions. The positions of orthogonal geometric projections of the grip openings on the fourth fold lines coincide with the positions of an orthogonal geometric projections of the complementary grip openings on the fourth fold lines.

Optionally, the reinforcement panels have the same length in a direction perpendicular to the octagonal base panel as the first wall panels, in which case the reinforcement panels have recesses whose projections are formed at free edges opposite the fourth fold lines. Orthogonal geometric on the first fold lines coincide with the positions of the lace openings.

Detailed description of some embodiments

In relation to Fig. 1, reference numeral 20 generally designates a die-cut plate made of cardboard sheet, corrugated cardboard, plastic, or corrugated plastic in accordance with an embodiment of the present invention, and in relation to Fig. 2 , reference numeral 30 generally designates an octagonal stackable tray according to the present invention obtained from the bending and joining of parts of the die-cut plate 20 of Fig. 1.

The die-cut plate 20 of Fig. 1 comprises an octagonal central base panel 1 having eight sides, and four first wall panels 2 and four second wall panels 3 arranged alternately around the octagonal base panel 1. The first four panels of wall 2 are respectively linked to four alternate sides of the eight sides of the octagonal base panel 1 by first fold lines 4, and the four second wall panels 3 are respectively linked to the other four alternate sides of the eight sides of the octagonal base panel 1 by a second fold lines 5.

In the octagonal tray 30 of Fig. 2, the first and second wall panels 2, 3 are folded by the respective first and second fold lines 4, 5 forming right angles with respect to the octagonal base panel 1. In the die-cut plate 20, the second fold lines 5 are slightly closer to a center of the octagonal base panel 1 than the first fold lines 4 and, consequently, in the octagonal tray 30 the second wall panels 3 are located slightly further inwards of the octagonal tray 30 than the first wall panels 2.

The die-cut plate 20 of Fig. 1 further comprises fixing fins 7 linked to both sides of each of the first wall panels 2 by a third fold lines 6, and reinforcement panels 9 linked to two of the first Wall panels 2 opposed by a fourth fold lines 8, where the third fold lines 6 are perpendicular to the first fold lines 4 and the fourth fold lines 8 are parallel to the first fold lines 4.

In the octagonal tray 30 of Fig. 2, the fixing fins 7 are folded by the third fold lines 6, superimposed and joined by adhesive to portions of an outer surface of the second adjacent wall panels 3 immediately adjacent to edges sides thereof, and the reinforcement panels 9 are folded by the fourth fold lines 8, superimposed and bonded by adhesive to interior surfaces of the respective first wall panels 2. The first wall panels 2 and the corresponding panels of reinforcement 9 have common upper edges 16 constituted by the fourth fold lines 8.

Both the first wall panels 2 with the reinforcement panels 9 superimposed and bonded together by adhesive thereto and the second wall panels 3 with the fixing fins 7 superimposed and bonded by adhesive to them largely constitute double walls. thickness for octagonal tray 30.

width slightly greater than the thickness of said cardboard sheet, corrugated cardboard, plastic,

or corrugated plastic.

Thus, the octagonal base panel 1 of the octagonal tray 30 of Fig. 4 has lace openings 12 sized and positioned properly so that the socket tongues 11 of another identical octagonal tray 30 located in one lower position in a stacking situation.

Fig. 5 shows a die-cut plate 20 which is a variant of the embodiment shown in Fig. 3, where the first four wall panels 2 opposite two to two are linked to respective reinforcement panels 9, and have respective handle openings 13 and concave cutting lines 10 defining respective lace tongues 11, and where the octagonal base panel 1 has four lace openings 12 adjacent and parallel to the first four bending lines 4. From the die-cut plate 20 of Fig. 5 an octagonal tray (not shown) similar to that described above in relation to Fig. 4 is obtained but including four reinforcement panels 9, four handle openings 13, four snap tabs 11 and four snap openings 12 on four opposite sides two to two of it.

Figs. 6 and 7 respectively show a die-cut plate 20 according to yet another embodiment of the present invention and an octagonal tray 30 obtained from the die-cut plate 20 of Fig. 6.

The die-cut plate 20 of Fig. 6 is analogous to that described above in relation to Fig. 3, with the difference that, here, the first two opposite wall panels 2 that do not have handle openings 13 are also linked to respective reinforcing panels 9 by corresponding fourth bending lines 8 and concave cutting lines 10 are defined which define respective lace tongues 11. Correspondingly, the octagonal base panel 1 includes two additional adjacent lace openings 12 and parallel to the first two fold lines 4 associated with the first two opposite wall panels 2 that do not have handle openings 13.

Another difference of die-cut plate 20 of Fig. 6 with respect to that described in relation to Fig. 3 is that the reinforcement panels 9 associated with the first two opposite wall panels 2 that do have handle openings 13 have the same length in a direction perpendicular to the octagonal base panel 1 than the first wall panels 2, and have complementary handle openings 14 that are equal in shape and dimensions to the handle openings 13 and that are located in positions

wall 2 and the corresponding reinforcement panels 9, four lace tabs 11 protruding from the common upper edges 16, and four lace openings 12 formed in the octagonal base panel 1.

For the purposes of the octagonal prismatic container 40, the lace tabs 11 and the openings

5 of lace 12 could be omitted in the octagonal tray 30 of Fig. 10, since they have no function in the octagonal prismatic container 40. However, the lace tabs 11 and the lace openings 12 serve to temporarily store so stacked octagonal trays 30 obtained from the folding and joining of parts of successive die-cut plates 20, for example by means of a forming machine

10 boxes, waiting to be used as bases or covers of octagonal prismatic containers 40.

In an alternative embodiment not shown of the octagonal tray 30, the reinforcement panels 9 are superimposed and bonded by adhesive to outer surfaces of the respective first wall panels 2. In another alternative embodiment not shown of the octagonal tray 30, the fixing fins 7 are superimposed and bonded by adhesive to interior surfaces of the second adjacent wall panels 3. In yet another alternative embodiment not shown of the octagonal tray 30, the first and second wall panels 2, 3 are inclined relative to the octagonal base panel 1. In another additional alternative embodiment not shown of the octagonal tray 30, the tabs of

20 fittings 11 are part of a panel that includes the first wall panels 2 and are coplanar with first wall panels 2, and the recesses 15 are formed at edges of the first wall panels 2 adjacent to the first fold lines 4 .

The scope of the present invention is defined by the appended claims.
