Description

DESCRIPTION OF THE FIGURES

(1) The invention will be described hereinbelow in at least one preferred embodiment as a non-limiting example, with the aid of the enclosed figures in which:

(2) FIG. 1 shows a perspective view of the semi-open container in which one sees the box 1 composed of base 1.a, cover 1.b and lateral edges 1.c; above the base, one sees the support layer 1.d and the plate 2 made of slate represented in gray; above the plate 2, a pizza cut into slices is depicted. In this embodiment, the cover 1.b is provided with four holes 3.a of the ventilation system 3 and a support system 4 constituted by cardboard blades arranged as a cross on the internal surface of the cover 1.b.

(3) FIG. 2 shows a section of the container depicting the box 1 composed of base 1.a, cover 1.b and lateral edges 1.c, closed; at the interior thereof, one sees the support layer 1.d, with the groove 1.z, which supports the plate 2 on which the pizza is abutted. Between support layer 1.d and base 1.a, air space 6 is visible that is traversed by the holes on the base 3.b, which are vertically aligned with the holes on the cover 3.a from which the heat of the pizza exits, represented by the wavy arrows.

(4) FIG. 3 shows the same version of the container described in the preceding figure in the completely open configuration with the cover 1.b rotated around one of the lateral edges 1.c until it touches the external surface of the base 1.a. One sees the holes on the base 3.b and the holes on the cover 3.a perfectly aligned in vertical sense in order to allow the passage of the air indicated with the wavy arrows. Also in this figure, one sees the air space 6 present between the base 1.a and the support layer 1.d, with the relative groove 1.z, and the plate 2 that carries the pizza.

(5) FIG. 4 illustrates a section of the container in which one sees, in closed configuration, the box 1 composed of base 1.a, cover 1.b, lateral edges 1.c, support layer 1.d with the groove 1.z, plate 2, ventilation system 3 with holes on the cover 3.a and holes on the base 3.b and air space 6 which, in this particular embodiment, is provided with a reinforcement structure 5; another particular feature of this version of the box 1 is the support 4 present on the internal surface of the cover 1.b.

(6) FIG. 5 illustrates the container as in the preceding figure but in completely open configuration with the cover 1.b rotated 360° around one of the lateral edges 1.c until it touches the external surface of the base 1.a. One sees the holes on the base 3.b and the holes on the cover 3.a perfectly aligned in vertical sense in order to allow the passage of the air indicated by the wavy arrows. One sees the air space 6 which, as in the preceding figure, is provided with a reinforcement system 5, and the plate 2 which carries the pizza. One also sees the support 4 which in open configuration acts as an abutment base against the surface of the table on which the container is placed.

DETAILED DESCRIPTION OF THE INVENTION

(7) With reference to FIG. 1, the container for foods of the present invention is represented, in semi-open position and with a round pizza at its interior. The box 1 is of common type, constituted by a base 1.a, not visible in the figure, lateral edges 1.c and a cover 1.b., and these parts are adapted to be fit with each other in a reversible manner in order to allow closing the box 1 while, for example, it is transported from the store to home. Once the place has been reached where it is intended to eat the foods, the user opens the box 1, making the cover 1.b rotate 360° around one of the lateral edges 1.c until the external surface of said cover 1.b comes into contact with the external surface of the base 1.a.

(8) Inside the box, the user will find the foods abutted against a thin plate 2, with preferred thickness of 5 mm, or in any case comprised between 1 mm and 10 mm, which has been heated in the same oven as the foods and which, therefore, maintains the heat thereof for a long period. This characteristic prevents the unpleasant sensation of consuming baked foods that have cooled down. Said plate 2 can have one or more holes, with preferred dimension of 2 cm, or in any case comprised between 2 mm and 5 cm, on its surface which allow the free circulation of hot air inside the box 1 and through the plate 2 itself. The preferred but non-limiting choice of slate as constituent material of the plate 2 is due not only to its property of retaining heat for a long period but also due to its non-toxicity, to its shear strength and since it can be washed and reused.

(9) The plate 2 just described does not lie directly on the base 1.a of the box 1 in order to prevent overheating it; rather, it lies on a support layer 1.d placed at a certain distance from said base 1.a and separated therefrom by an air space 6. Possibly, in one possible embodiment of the present invention, said support layer 1.d can have a groove 1.z at the contact surface with said plate 2 adapted to act as an abutment for said plate 2 in order to prevent any movement thereof, except the vertical movement upward which would only occur in case of overturning of the box 1; the latter possibility is rather improbable.

(10) The air space 6 existing between said support layer 1.d and said base 1.a, can be provided with an internal reinforcement structure 5 (FIG. 4 and FIG. 5) which serves to preserve the structure of the box 1 also under strong pressures, after a light initial crushing. Said reinforcement 5, in addition to ensuring the resistance also under strong pressures or crushing, is constituted by elements with stackable form, which allows adding already-existing reinforcement layers 5 in order to increase the height of the air space 6. This characteristic can be useful if a plate 2 is used that is particularly hot, adapted to complete the cooking of the foods and not only to maintain them at the right temperature.

(11) It is observed that, as visible in FIG. 1, the cover is provided with a plurality of holes 3.a which allow the exit/outflow of the heat of the foods without condensation being formed inside the closed box 1. When the box is opened, as described, the holes on the cover 3.a are situated at the same number of holes on the base 3.b (FIG. 3 and FIG. 5). This ensures that, following the pressures due to cutting operated by the user, a pump effect is generated that draws the surrounding air into the ventilation system 3, assisting the plate 2 to be cooled more quickly. The efficiency of said ventilation system 3 is increased by the presence of a support system 4 constituted, in the preferred embodiment of the present invention, by a pair of cardboard blades arranged as a cross on the internal surface of the cover 1.b. This system has two uses: when the box is closed, (FIG. 4) it prevents the cover 1.b from touching the foods in case of crushing of the box, and when the box is completely open (FIG. 5) it determines a space between the support surface and the box 1 which allows the best operation of the ventilation system 3.

(12) In order to be better adapted to each type of food, the plate 2 can be made both round and square, with preferred dimensions of the diameter or of the side of 35 cm, but it can be made of any other dimension comprised between 10 cm and 60 cm.

(13) Finally, said plate 2 can be decorated by a serigraphy depicting a city or an event, in a manner such that after use, it can act as a memento/souvenir.

(14) Finally, it is clear that modifications, additions or variations that are obvious for the man skilled in the art can be made to the invention described up to now, without departing from the protective scope provided by the enclosed claims.
