DETAILED DESCRIPTION

[0074] Throughout this description, the expressions embodiment, implementation, and advantageously or the like mean that a certain peculiarity, structure or characteristic is included in at least one embodiment of the invention set forth in the present description, but it is not excluded that the same peculiarity, structure and/or characteristic is common to all embodiments of the invention or that the same peculiarity, structure or characteristic is absent in one or more embodiments of the invention.

[0075] It should also be noted that terms such as less/lower, lateral/side, rear, upper/greater, front and the like are reference terms that should not be construed as restrictive terms.

[0076] Referring to the attached Figures, a food package is indicated as a whole by the number 100.

[0077] In accordance with an embodiment of the invention, both containers 101, 102 are made of a material suitable for microwave cooking. More precisely, this material comprises (is) a polymeric material (e.g. selected from PP and/or PET).

[0078] The package 100 comprises a first container 101 and a second container 102, each of which has a respective opening 101a, 102a to access an inner volume 101b, 102b suitable to house a food product. More precisely, the first container 101 contains a first food product 1 and the second container 102 contains a second food product 2.

[0079] With reference to FIG. 1, the opening 101a, 102a of each container 101, 102 is closed (in particular, in a sealed manner) by a respective closing element 101c, 102c, for example a cover, a film, a layer, a lid or similar. In particular, if films or lids are used, they are advantageously heat-welded to their respective container. Thus, the closing elements 101c, 102c are advantageously independent of each other and can be removed individually, so that the end user can access the contents of one or both containers 101, 102, for example to taste the food products before preparation or to combine their contents.

[0080] In more detail, the package 100 is therefore able to assume a preservation condition, in which the containers 101, 102 are separated and closed by their respective closing elements 101c, 102c, in such a way that the food products contained therein are preserved from the external environment and are kept divided. In particular, in the preservation condition, the containers 101, 102 are placed on top of one another (FIG. 1) and are preferably wrapped in a band (known per se and not illustrated) that reciprocally holds them in position. This band is, for example, made of cardboard.

[0081] With particular reference to FIGS. 1, 2, 5 and 6, the package 100 can also have an operating condition in which the user first opens the containers 101, 102 by disconnecting the respective closing elements 101c, 102c and then couples the containers at their respective access openings 101a, 102a.

[0082] In particular, both containers 101, 102 comprise respective edges 111, 112 arranged around their respective access openings 101a, 102a. In greater detail, the edges 111, 112 are shaped to engage with each other in such a way that the access openings of the containers face each other, so that, for example, the first container 101 is coupled in an upside-down position with the second container 102. In this way, the package 100 has an operating configuration in which a chamber 103, also called cooking chamber, is defined whose containing volume is formed by the joining of the inner volumes 101b, 102b of the individual containers 101, 102.

[0083] The food products 1 and 2, previously housed in their respective containers 101, 102, are thus joined together and enclosed in the cooking chamber 103. Subsequently, the user can easily subject the configured package 100 to a heating step, i.e. with the cooking chamber 103 already created, for example by placing the package in a microwave oven.

[0084] In this regard and according to one aspect of the invention, the first container 101 contains a first food product 1 with at least one liquid component (for example the first food product 1 is selected from a sauce, a seasoning, a broth and the like), while the second container 102 contains a second food product 2 with at least one solid component, (for example the second food product 2 is selected from pasta, stuffed pasta, rice, meat and the like). In particular, the first food 1 comprises water.

[0085] When the containers are coupled together to make the above-mentioned cooking chamber 103, the food products 1 and 2, initially separated in their respective containers 101, 102, are joined and enclosed within the cooking chamber (in particular, in contact with one another) and can thus be subjected to a common heating step whereby the liquid component of the first food product 1 causes the cooking of the second food product 2. In other words, the liquid component of the first food product acts as a cooking liquid. For example, if the first food product 1 is a sauce and the second food product 2 is pasta, the liquid component of the sauce mixed with the pasta determines its cooking, similarly to what happens when the pasta is in a traditional pot containing cooking water. In an advantageous way compared to the traditional preparation with cooking water, the cooking carried out in the package according to the invention provides the final dish with particular organoleptic characteristics, since the pasta is cooked directly in the sauce.

[0086] This means that the package makes it possible to preserve the food products 1, 2 separately (the so-called preservation condition of the package 100) and to prepare and heat them already joined together (the so-called operating condition of the package 100).

[0087] Another important advantage is that the package 100 in the operating condition, i.e. having the containers 101, 102 coupled with one another at the edges 111, 112, prevents product outflows during the preparation and cooking steps.

[0088] In accordance with one embodiment, the containers 101, 102 are firmly coupled with one another. Advantageously, the firm coupling of the containers 101, 102 at their respective access openings 101a, 102a ensures that the overpressure (with respect to the outer pressure) that develops inside the cooking chamber 103 as a result of the evaporation of a liquid component of the food products, for example sauce, after heating does not cause the separation of the containers, thus causing the outflow of food products. Therefore, the package 100 allows the user to cook the food products without the risk of getting dirty or soiling the surrounding environment, for example the inner space of a microwave oven.

[0089] Referring in particular to FIGS. 1 and 2, the edge 111 of the first container 101 is advantageously counter-shaped with respect to the edge 112 of the second container 102. In particular, each edge 111, 112 delimits the access opening 101a, 102a of the respective container 101, 102, i.e. each edge is close to a margin of the respective access opening.

[0090] In accordance with the embodiment of the invention illustrated in FIGS. 2 and 6, the edge 111 has a collar 121 which (projects laterally outwards from the access opening 101a of the first container 101 and) is designed to rest against (on) a support surface 122 of the edge 112. In particular, the support surface 122 extends from (at least) one side wall (more precisely, from the side walls) of the second container 102, more particularly towards the inside of the container 102 itself. More specifically, the support surface 122 extends from the edge 112.

[0091] Advantageously but not necessarily (see in particular FIGS. 5 and 6), at least one projecting element, for example an indentation 123 (in particular, a plurality of projecting elements, for example indentations 123) is arranged at the edge 112 of the second container 102. In particular, when the package 100 is in the operating condition, the first container 101 is in an upside-down position with the collar 121 substantially snap-fitted between the indentations 123 and the support surface, so that the containers 101, 102 remain firmly coupled during the subsequent step of preparation and heating of the final dish.

[0092] In particular, the indentation 123 is arranged in such a way as to define with the support surface 122 a cavity configured to house at least one portion of the collar 121. More precisely, the indentation 123 is placed above the support surface 122.

[0093] In accordance with other embodiments, alternatively or in combination with one or more indentations, one or more undercuts may be provided, preferably made at the edge 112 of the second container 102 and shaped to receive portions of the edge 111 of the first container 101.

[0094] With reference to FIG. 3, the access opening 101a of the first container 101 is configured to receive a bottom 102d of the second container 102 to allow the latter to be housed (at least partially) in the inner volume of the first container 101. In this way, at the end of the preparation step, a user can grasp and handle the second container 102 through the first container 101. In fact, at the end of the heating/cooking step, the containers 101 and 102 are separated and the one containing the final dish tends to be much warmer than the other one. The possibility of inserting the bottom 102d of the second container 102 into the first container 101 allows the user to handle the second container 102 without the risk of burning himself and therefore allows an on-the-go consumption of the food directly in the container.

[0095] With reference to FIG. 3, the bottom 102d of the second container 102 is shaped (and the container 101 is shaped) in such a way as to abut at a predetermined distance from a bottom 101d of the first container 101, so as to define a hollow space 104 between the two containers 101, 102. In particular, the body of the first container 101 to which abuts the bottom 102d of the second container 102 is tapered, so as to maintain said distance through a form interference between the two containers 101 and 102.

[0096] With reference to the Figures, the container 101 comprises a pair of knurled portions 105 to allow a user's grip. Advantageously, the knurled portion allows an appropriate friction and also prevents the user to burn himself when handling the containers after the food heating/cooking step. In accordance with a general concept of the invention, the second container can also be provided with one or more knurled portions.

[0097] As better shown in FIG. 2, advantageously but not necessarily, the second container 102 comprises a pair of gripping members, preferably a pair of opposite handles 106. In particular, the handles 106 are shaped as fins developing from the side walls of the container.

[0098] With reference to FIG. 4, according to some embodiments, a bottom 101d of the first container 101 can be housed in the access opening 102a of the second container 102, to close it, and a closing element 101c, for example a cover, a film or the like, is connected to the first container 101 to close (in particular, in a sealed manner) its access opening 101a. Unlike the configuration previously described and illustrated in FIG. 1, there is therefore no second closing element 102c connected to the second container 102. Also in this case, however, the containers can be configured between a preservation condition, in which the bottom 101d of the first container 101 is housed in the access opening 102a of the second container 102 (so as to close, in particular seal, the access opening 102a itself), and an operating condition in which the closing element 101c is disconnected from the first container 101 and in which the containers are coupled at the respective access openings 101a, 102a to create the aforementioned cooking chamber 103, according to the methods described above and as shown in FIG. 2.

[0099] Also in this case, it is preferable that the containers 101, 102 are firmly coupled with one another when the package is in the operating condition.

[0100] With particular reference to FIG. 4 (in the preservation condition), according to some embodiments, the first container 101 is completely housed in the second container 102 and the depth of the first container 101 is lower than the depth of the second container 102 so that, between the bottom 101d of the first container 101 and the bottom 102d of the second container 102 a containing volume is defined to receive a food product (typically the second food product 2).

[0101] More precisely but not necessarily, the first container 101 is counter-shaped with respect to the access opening 102a of the second container 102 and is preferably welded to a support surface 122 (in particular, as defined above) arranged adjacent to the access opening 102a of the second container 102.

[0102] With reference to the description already provided in relation to the package 100 according to the invention, a use of the package 100 to prepare food products to be consumed will now be described.

[0103] The use comprises the following steps: [0104] (at least partially) removing the closing elements 101c and 102c from the respective containers 101 and 102 (i.e., removing the container 101 from the container 102 and removing the closing element 101c from the container 101); [0105] joining the first food product 1 to the second food product 2 inside the second container 102 (and/or the first container 101), as shown in FIG. 2; [0106] coupling the containers 101 and 102 at their respective access openings 101a and 102a to create a chamber 103 (also called cooking chamber) with a containing volume defined by the joining of the inner volumes of the containers 101 and 102 (as shown in FIG. 2, the food products 1 and 2 remain joined and enclosed within the chamber 3); [0107] heating the chamber 3 by means of a heat source (in particular a microwave source) (in particular until the liquid component of the first food product 1 reaches its boiling temperature) so as to cause the cooking of the second food product 2.

[0108] In particular, the step of coupling the containers 101 and 102 is subsequent to the step of removing (at least partially) the closing elements 101c and 102c.

[0109] Advantageously but not necessarily, the use comprises a mixing step (in particular, subsequent to the step of joining the first product 1 to the second product 2), during which the containers 101 and 102 coupled to one another (i.e. the package 100 in its operating condition) are shaken so as to mix together the first and second food products 1 and 2. In particular, the mixing step follows the step of coupling the containers 101 and 102 and takes place (at least partially) before the heating step of the chamber.

[0110] For example, if the first food product 1 is a sauce and the second food product 2 is pasta, the liquid component of the sauce mixed with the pasta determines its cooking, similarly to what happens when the pasta is in a traditional pot containing cooking water. In an advantageous way, therefore, the use allows both to preserve food products 1, 2 separately and to prepare a final dish.

[0111] In accordance with one embodiment, it is provided to extend the heating step of the chamber 103 by a predetermined amount of time in order to maintain the boiling temperature for a predetermined amount of time. In this respect, the heating step is carried out at a temperature value between about 80 C. and about 130 C. for an amount of time of not less than about 2 minutes, more precisely between about 2 minutes and about 8 minutes.

[0112] According to an embodiment, the step of coupling the containers comprises the sub-step of coupling them in a firm manner.

[0113] In accordance with a further embodiment and as shown in FIG. 1, a transport step of the containers 101, 102 is provided for bringing them into a position on top of one another, before the step of removing the closing elements. Preferably, there is also a step of wrapping the containers 101, 102 with a band during the transport step, to reciprocally hold them in position.

[0114] In accordance with a further embodiment, the use also comprises the following steps: [0115] uncoupling the containers 101, 102 at the end of their heating; [0116] at least partially inserting a bottom 102d of the second container 102 into the first container 101 (FIG. 3), so that a user can pick up the second container 102 through the first container 101.

[0117] It has been experimentally found that the invention achieves its intended aims. In particular, a package in accordance with the invention allows an easy preparation of a dish and a convenient on-the-go consumption, i.e. even under take-away conditions, directly inside the package itself. In fact, the possibility of handling the container of the ready-to-eat (hot) food through the other container allows the consumer to avoid burning and simplifies the consumption when moving from one place to another.

[0118] In addition, the firm coupling of the containers to define a cooking chamber prevents the risk that the consumer may dirty himself or the surrounding environment during the preparation and thus simplifies the meal preparation even for consumers with little culinary experience and/or hasty. This coupling also allows for faster and more efficient cooking.
