[0029] FIG. 6 shows a perspective view of two single containment elements, as in FIG. 1A, before being stacked on top of each other;

[0030] FIG. 7 shows a schematic view of the different steps related to the realization of the food container, object of the present invention, which is obtained by coupling two single containment elements.

[0031] With reference to the above-mentioned drawings, a single containing element for containing food is generically indicated with the numerical reference 10. Said single containment element 10 is made of compostable type materials and, in particular, is preferably made of cellulose pulp.

[0032] Advantageously, the single containment element 10, regardless of the chosen embodiment, it is made with a minimal design and in a single mold, reducing the production costs.

[0033] The aforementioned single containment element 10 includes a base 11 having an outer perimeter with an irregular geometry, substantially in the form of a flower corolla, in such a way as to be able to advantageously contain foods such as pizzas having not perfectly round shapes. In particular, each single containment element 10 comprises, on the relative base 11 and substantially radially, at least four first circular sectors 15, converging towards a center P coinciding with the center of symmetry of the base 11, and at least four second circular sectors 25, also converging with the center P of the base 11. Moreover, said second circular sectors 25 have a lower angular amplitude than said first circular sectors 15, as visible in FIG. 2A.

[0034] In particular, always with reference to FIG. 2A, at least one of said first circular sectors 15 is alternated with at least one of said second circular sectors 25. Advantageously, the alternation between the first sectors 15 and the second sectors 25 on the base 11 is apt to realize, at a structural level, the aforementioned flower corolla geometry that is such as to be able to advantageously contain foods such as pizzas having not perfectly round shapes.

[0035] Further, in preferred embodiments, the base 11 includes a first surface (FIG. 1A), facing the inside of the single element 10, in particular, in the area suitable to come into contact with the food, and a second flat surface (FIG. 1B), facing the outside of the single element 10, therefore in the opposite direction to the first surface, in order to allow the single element 10 to be placed on a plane. In particular, the containment elements 10, thanks to their identical geometry and structure, as visible in FIG. 6, are, advantageously, stackable one on top of the other in such a way as to facilitate storage and transport, because the supply spaces are reduced.

[0036] As can be seen, by way of example, in FIG. 2A, the base 11 of the single element 10, in correspondence with the aforementioned first surface, comprises an internal surface 45 and a supporting surface 35 which is in relief and raised with respect to the internal surface 45.

[0037] Moreover, the supporting surface 35 includes ribs with preferably radial geometries, in which all axes with inclination, preferably at 45°, depart from the center P of symmetry placed at the center of the internal surface 45 of the base 11, in such a way as to structurally create a series of ventilation channels 75 and 85, (FIG. 1A) in which, the ventilation channels 85 also allow to facilitate the cutting into slices of the food.

[0038] Moreover, the aforesaid ribs have the advantage of avoiding the food to come into contact with eventual liquids and/or oil, as well as to guide and therefore allow the escape of the steam in excess.

[0039] In particular, said ventilation channels 85 are convergent with the center P and are symmetrically developed with respect to the C-axes of the base 11, as visible in FIG. 5.

[0040] Advantageously, the single containment element 10 further has a tapered relief edge or double-walled, double-height side wall 20. Advantageously, said ridge-like side wall 20 is protuding, e.g. in angled way, from the base 11, following the entire perimeter thereof in a crown-like manner, in a substantially wavy pattern, as visible, by way of example, in FIGS. 2B and 2C.

[0041] With reference to FIG. 2B, the double-walled side wall 20 is structured to include at least one projecting profile 22 of height H2 and at least one valley 23 of height H1, according to a height variation ΔH, such that the projecting profiles 22 and valleys 23 are alternating on the side wall 20.

[0042] More specifically, on each inner wall, of the tapered side wall 20, which is located in correspondence with at least one of the at least four first circular sectors 15, there is a joint 55, preferably beak-shaped; on the other hand, on each outer wall of the tapered side wall 20, which is located in correspondence with at least one of the at least four second circular sectors 25, there is a hole preferably with a shape suitable for containing the joint 55.

[0043] Advantageously, the structure of the single containment element 10 is such that it is stackable, for example with other containment elements 10, and thus easy to be stored.

[0044] In detail, each single containment element 10 can be coupled with a further containment element 10 and, each of them can act as both a plate and as a lid in the realization of the container device 100. In addition, advantageously, each single containment element 10 acting as a lid can be stacked under the single element 10 acting as a plate during consumption; alternatively, the element 10 acting as a lid can also be used as a further plate and/or recovered for future use.

[0045] Going into detail, as schematically visible in FIGS. 5 and 7, the coupling of two containment elements 10, for the creation of the relative container device 100 closed, is obtained by reversing of 180° with respect to the axis C and, in direction L, the single containment element 10, used as a lid and, subsequently, always rotating the same containment element 10, preferably, by 45 degrees, in direction R, so as to couple it with the further element 10 acting as a plate (FIGS. 3A, 3B, 4A-4C, 5, 7); the rotation angle according to the direction R is a function of the particular geometry of the element 10. In particular, advantageously, at least two containment elements 10 are joined and coupled to each other, preferably, in the direction U perpendicular to the axis C (FIGS. 5 and 7) and have, respectively, relative first surfaces of the base 11 facing each other, so that each joint 55, as described above, of a first element 10 will couple with the corresponding hole 65 of a second contaiment element 10 and vice versa.

[0046] In fact, the food containers used today are made with a plurality of molds: a specific mold for the realization of the base of the container and one for the realization of the lid. In this way, not only the costs for the realization of the container increase but, further, since the aforesaid base and lid will have different shapes, the size of the container when closed is greater than in the technology object of the present invention.

[0047] In particular, according to the present invention, thanks to the innovative interlocking interpenetrating coupling system present, preferably, on the whole perimeter of the single element 10, when assembled, the container device 100 presents, advantageously, a smaller footprint, especially in height, and therefore a smaller thickness.

[0048] In detail, as can be seen in FIGS. 3B, 4B and 4C, in the food container device 100, thus made, there will be created, structurally, advantageously for the geometry of each element 10 acting to form the container 100, lateral slots 95, preferably eight, equidistant from each other. Advantageously, since each element 10 alternately comprises projecting profiles 22 and valleys 23, as described above, said lateral slots 95 are located at the coupling points between the two elements 10 composing the container 100, in particular said slots 95 are structurally realized at the contact point between the two valleys 23 of the two elements 10 coupled to form the container 100.

[0049] Advantageously, such slots 95 allow air exchange between the inside and the outside of the container device 100, in correlation with convective air movements, avoiding the formation of excess vapors that, by condensing, could fall on the food, altering its quality.

[0050] Alternatively, the single containment element 10 having the function of a lid can be, advantageously, used as a second course or, in case it is still intact, stored and therefore recovered. Always advantageously, for the composition of a food container device 100, no pre-assembly phase by the operator is foreseen; this allows to speed up the preparation while maintaining a safe and practical device for transport, in favor of companies that carry out delivery. In further preferred, but not limiting, embodiments, said container device 100 may be stacked with at least one additional container device 100 and/or with a single element 10.

[0051] The features of this invention, as the advantages, are apparent from the description provided; finally, it is apparent that this invention is described by way of example only, without limiting the scope of application, according to its preferred embodiments, but it shall be understood that the invention may be modified and/or adapted by experts in the field without thereby departing from the scope of the inventive concept, as defined in the claims herein.
