    Description


    [0001] This invention relates to a package for preserving food products and preparing them for consumption, of the type described in the preamble to claim 1.

    [0002] This invention also relates to a method for preparing food products for consumption, of the type described in the preamble to claim 17.

    [0003] As is known, in the food industry there has always been a need to make packages able to guarantee the preservation of food products for a desired period of time (called the "shelf-life") and at the same time able to speed up preparation of the food products for consumption.

    [0004] In particular, in the "fresh" food products sector, for example tortelli, tortellini or other pasta made using eggs, the preservation of the organoleptic properties is extremely important, both to guarantee a top quality product and to prevent the growth of bacteria. Specifically with reference to the fresh food products sector, there is also a need to combine two or more products in the same package, for example a main dish and the relative dressing, so as to speed up the step of preparation for consumption.

    [0005] According to the prior art, there are multiple packages, including separate containers, one for the main dish - for example fresh tortellini or pasta - and one for the dressing. In particular, there are prior art packages comprising a main bag, holding a pouch containing a single serving of the main dish, for example pasta made using eggs, typically tortellini, and a tub containing a single serving of dressing, for example a sauce to be served with the pasta.

    [0006] The consumer opens the main bag to take out the pouch and the tub. Then, he empties the pasta contained in the pouch into a pan for cooking. He then adds water to the sauce contained in the tub, to dilute it, and pours the sauce diluted with water into the pan. Finally, he cooks the pasta, now dressed with the sauce, in the pan.

    [0007] The main disadvantage of packages made according to the prior art summarised above is that they do not allow quick and easy preparation of the main dish for consumption. In fact, the consumer, having to handle two separate containers, must be particularly careful when pouring the dressing into the pan. Moreover, since the dressing in the tub has to be diluted with water, the step of preparation for consumption is disadvantageously lengthy and complex.

    [0008] Another disadvantage of the packages made according to the prior art is that of exposing the consumer to the risk of getting dirty, especially when pouring into the pan the dressing, which is often semi-liquid and in any case further diluted with water.

    [0009] A further disadvantage of the prior art packages is that they are bulky, since they consist of several separate containers, each with its own wrapper or packaging. With regard to that, the prior art packages have the further disadvantage of being difficult to dispose of after the product has been consumed, since the main bag, the pouch and the tub are usually made of different materials. According to another prior art reference in document US 4,596,713, there are packages for microwave ovens which during heating are able to release a food additive contained in a pocket in the package. Such a package is used in particular for preparing popcorn.

    [0010] Document FR 2929491 describes a package in accordance with the preamble of claim 1.

    [0011] In this context, the technical purpose which forms the basis of this invention is to provide a package for preserving food products and preparing them for consumption that overcomes the above mentioned disadvantages of the prior art. In particular, the aim of this invention is to provide a package able to allow quick and easy preparation of food products for consumption.

    [0012] With regard to that, another aim of this invention is to provide a package able to make easy, even for consumers who are not culinary experts, the preparation and cooking of food products whose cooking is challenging. Another aim of this invention is to provide a package able to prevent the risk of the end consumer getting dirty, during the step of preparing the products for consumption.

    [0013] Another aim of this invention is to provide a package which is not bulky and which is easy to transport. Another aim of this invention is to provide a package which is easy to dispose of after the food products have been consumed.

    [0014] Another aim of this invention is to provide a package able to contain two different food products, preventing both the growth of bacteria and the exchange and absorption of substances, for example water, between the two products.

    [0015] Also a technical purpose of this invention is to provide a method for preparing food products for consumption.

    [0016] The technical purposes indicated and the aims specified are substantially achieved by a package for preserving food products and preparing them for consumption and by a method for preparing food products for consumption comprising the technical features described in one or more of the appended claims.

    [0017] Additional features and advantages of this invention are more apparent in the non-limiting description of a preferred, non-limiting embodiment of a package for preserving food products and preparing them for consumption, as shown in the accompanying drawings in which:
    • Figure 1 is an axonometric top view of a package according to the invention;
    • Figure 2 is a side cross-section of the package of Figure 1;
    • Figures 3 and 4 are, respectively, an axonometric top view and bottom view of the package of the previous figures, in an open configuration;
    • Figure 5 is a cutaway view of the package of the previous figures, in an operating configuration;
    • Figures 6 to 8 are three views of a first construction detail of a package according to the invention;
    • Figures 9 to 11 are three views of a second construction detail of a package according to the invention.


    [0018] In particular with reference to Figures 1, 2 and 5, the numeral 1 denotes as a whole a package for preserving food products and preparing them for consumption in accordance with this invention.

    [0019] With reference to the accompanying drawings, in particular Figure 2, the package 1 comprises a first container 2 containing a first food product 200 and a second container 3 containing a second food product 300. The first and second containers are coupled to each other.

    [0020] In the preferred embodiment, the containers are made of polypropylene combined with ethylene vinyl alcohol (acronym: EVOH) to guarantee non-permeability of gases. In alternative embodiments, the containers may be made of polyethylene terephthalate (acronym: PET) or crystallised polyethylene terephthalate (acronym: CPET). In particular with reference to Figures 6 and 9, the first and second containers each comprise an access opening 2a, 3a. In particular, as shown in Figure 4, the containers are coupled to each other with the respective access openings 2a, 3a facing each other.

    [0021] In particular with reference to Figures 2, 4, 9 and 10, the package 1 comprises a separator sheet 4 interposed between the first and second containers, for keeping the food products housed in the respective containers separate in a preservation operating configuration. In particular, the separator sheet is interposed between the containers 2, 3 in such a way that it simultaneously closes both of the access openings 2a, 3a (Figure 2).

    [0022] In particular with reference to Figure 5, the separator sheet 4 is shaped in such a way that it breaks under the action of the pressure applied by steam which develops from at least one of the food products during a food product heating step to prepare them for consumption. Consequently, following breakage of the separator sheet, the first food product makes contact with the second food product. For that purpose, the separator sheet 4 comprises at least one portion 4a with a reduced transversal thickness, forming a predetermined tear zone for breakage controlled by the steam pressure. In particular, the transversal thickness of the separator sheet at the tear zone is such that it results in the breakage of the separator sheet at a pressure value greater than 1 bar, preferably between 1 bar and approximately 1.5 bar. Preferably, the tear zone is formed by a line 34a positioned at a centre line of the separator sheet 4 and extending in a main direction of extension of the package 1.

    [0023] According to the embodiment illustrated in Figures 9 and 10, the separator sheet is a film made of heat-shrink plastic material. Preferably, the film is made of anti-condensation polypropylene with EVOH. In this case, the tear zone is formed by one or more cuts made with a laser and such that they reduce the transversal thickness of the film, but without compromising its properties which make it non-permeable to gases.

    [0024] In particular with reference to Figures 3, 4, 6 and 9, the access opening 2a, 3a of the containers 2, 3 have respective perimetric shapes which substantially match each other. Moreover, in the preferred embodiment illustrated in the accompanying drawings, the first container 2 is positioned above the second container 3 and is overturned, in such a way that, after the separator sheet 4 has broken, gravity makes the first food product flow into the second container, making contact with the second food product.

    [0025] According to an alternative embodiment of the invention, the first food product may have a higher moisture content than that of the second food product, thus, following the heating step and breakage of the separator sheet - and therefore contact with the second food product - the first food product causes the second food product to be cooked. For example, the first food product 200 may be a dressing, for example a sauce, and the second food product 300 may be fresh pasta, for example tortellini.

    [0026] In accordance with the preferred embodiment, the first and second food products have cooking times which are not less than 2 minutes, preferably between 2 minutes and around 8 minutes. In the embodiment in which the first food product is a dressing, for example a sauce, and the second food product is fresh pasta, for example tortellini, the cooking time of between 2 minutes and 8 minutes is what guarantees the formation - in the first container - of a steam pressure sufficient to make the separator sheet break and allow the first food product (for example, the sauce) to make contact with the second food product (for example, the fresh pasta), and cause the latter to be cooked. According to an alternative embodiment not illustrated, the second container, containing the pasta, may be fitted with a safety valve to prevent overpressures while the pasta is being cooked. In particular, the safety valve opens when a pressure value greater than approximately 1.5 bar is reached, allowing the steam to be vented.

    [0027] In the preferred embodiment, the first and second containers 2, 3 also contain an inert gas or a mixture of inert gases designed to preserve the food products. Preferably, the pressure of the gases in each container is equal to around 0.5 bar and even more preferably said gases are nitrogen (N2) or a mixture of carbon dioxide (CO2) and nitrogen (N2).

    [0028] With reference to the accompanying drawings, the first container 2 comprises a contact portion 2b extending around its access opening 2a, the contact portion being substantially shaped to match a corresponding housing recess 3b in the second container 3. The housing recess 3b in turn extends around the access opening 3b of the second container 3. In the preferred embodiment illustrated, for example in Figures 3, 6 and 7, the housing recess 3b is formed by a supporting base 3c connected to a vertical edge 3d.

    [0029] Advantageously, the contact portion 2b and the housing recess 3b provide the package 1 with a seal and rigidity, as well as allowing easy centring of the containers 2, 3 during container production.

    [0030] With reference to the accompanying drawings, the first container 2 comprises a collar 7 positioned around its access opening 2a, preferably in such a way that it surrounds the contact portion 2b (Figure 10). The second container 3 comprises an opposite collar 8 positioned around its access opening 3a, preferably in such a way that it surrounds the housing recess 3b (Figure 6). In particular, the opposite collar 8 extends from the vertical edge 3d of the housing recess 3b.

    [0031] The containers are coupled by heat-sealing the collars 7, 8. In particular, the collar 7 of the first container 2 is pressed, when hot, against the opposite collar 8 of the second container 3 until the material used to make the collars fuses together. For that purpose, the collars are made of plastic material, preferably in a single piece with the respective containers 2, 3, and therefore of polypropylene combined with ethylene vinyl alcohol (acronym: EVOH), of polyethylene terephthalate (acronym: PET) or crystallised polyethylene terephthalate (acronym: CPET).

    [0032] According to the invention, at least one of the containers 2, 3 comprises a grippable expansion allowing the containers to be pulled apart. With reference to the accompanying drawings, each container comprises a grippable portion 6, typically a tab, designed to be gripped by a user. Said grippable portions are suitable for forcefully pulling in opposite directions away from each other, to separate the containers. Preferably, each grippable portion 6 is formed on each container as an expansion of the collars 7, 8.

    [0033] It should be noticed that heat-sealing the collars 7, 8 made of plastic material is very advantageous, since, while guaranteeing that the containers are coupled to each other during production of the package, it does not require the application of excessive force by the user to separate the containers during the step of preparation for consumption.

    [0034] With reference to Figure 9, the separator sheet 4 is connected to a contact surface 5 positioned around the access opening 2a of the first container 2, between a perimetric edge 22a of the opening and the contact portion 2b. Preferably, the separator sheet 4 is heat-sealed, at its perimetric portions, to the contact surface 5 of the first container 2 (the sealing line is labelled "S" in Figure 10).

    [0035] With reference to Figure 9, the contact surface 5 has a surface area whose dimensions are such that it receives the film in the retracted configuration following its breakage after the heating. In fact, after breaking due to the steam pressure, the film tears and, being made of heat-shrink plastic material and being sealed to the contact surface 5, it contracts due to the heating, and is positioned on the contact surface. Advantageously, the contraction of the film and its positioning on the contact surface maximises transit cross-section available for the first food product to flow from the first container to the second container.

    [0036] According to the invention, a method for preparing food products for consumption comprises the following steps:
    • preparing a first container 2 containing a first food product;
    • preparing a second container 3 containing a second food product;
    • coupling the containers 2, 3 to each other;
    • interposing a separator sheet 4 between the containers 2, 3 for keeping the food products housed in the containers 2, 3 separate in a preservation operating configuration;
    • heating the food products in the respective containers, the heating step causing the formation of steam in at least one of the containers due to the evaporation of liquid present, in the form of moisture, in the food product contained in it.


    [0037] The heating step is carried out at least until, in at least one of the containers, a steam pressure value is reached such that it causes the separator sheet to break, resulting in the first food product making contact with the second food product without intervention by an operator.

    [0038] The step of interposing the separator sheet may be performed either before or after the step of coupling the containers.

    [0039] According to the invention, the steam pressure value which causes the separator sheet to break is greater than 1 bar, preferably between 1 bar and approximately 1.5 bar.

    [0040] According to the invention, the first food product has a higher moisture content than that of the second food product. The heating step is prolonged after breakage of the separator sheet at least until a boiling temperature is reached for the liquid present in the form of moisture in the first food product, meaning that the contact between the first food product and the second food product causes the latter to be cooked

    [0041] In particular, the heating step is performed at a temperature value of between approximately 80 °C and approximately 130 °C for a period of time which is not less than 2 minutes, preferably between 2 minutes and approximately 8 minutes.

    [0042] The invention operates as follows.

    [0043] The package is inserted in suitable food heating devices, for example a conventional oven, a microwave oven, etc.

    [0044] Then, after being heated, at least one of the food products, for example the first food product, begins producing steam in the respective container, until a steam pressure able to break the separator film at the predetermined tear zone is built up.

    [0045] After the film has broken, gravity makes the first food product flow into the second container and it makes contact with the second food product (Figure 5).

    [0046] With reference to the preferred embodiment and without in any way limiting the scope of the invention, the first food product has a higher moisture content than that of the second food product. In this case, following the heating step and breakage of the film, and therefore contact with the second food product, the first food product causes the second food product to be cooked. That situation corresponds, for example, to the case in which the first food product may be a dressing, for example a sauce, and the second food product may be fresh pasta, for example tortellini.

    [0047] After the film has broken, the torn film, being made of heat-shrink plastic material, contacts due to the heating, and is positioned on the contact surface 5 of the first container.

    [0048] At the end of the heating step, the user grips the grippable portions 6 and forcefully pulls them in opposite directions away from each other, to uncouple the containers 2, 3 (Figure 3).

    [0049] After the containers have been separated, the user can throw away the first container, on whose contact surface the torn film is positioned, and can eat the meal now ready in the second container, for example pasta dressed with sauce.

    [0050] The invention brings important advantages.

    [0051] First, a package according to this invention can allow quick and easy preparation of food products for consumption. Indeed, advantageously, automatic breakage of the separator sheet caused by the steam pressure and the consequent automatic contact between the first food product and the second food product, allow the food products to be prepared for consumption without any intervention by the end user.

    [0052] Another advantage is the fact that the package according to the invention is not bulky and is easy to transport. Moreover, comprising only two containers made of the same plastic material, it is easy to dispose of after the food products have been consumed.

    [0053] Advantageously, in the embodiment in which the first food product is a dressing, for example a sauce, and the second food product is fresh pasta, for example tortellini, the package according to the invention can surprisingly allow the preparation and dressing of fresh pasta even without boiling water which is normally needed to cook fresh pasta according to the prior art methods. Therefore, in light of this, the package according to the invention is particularly advantageous for allowing "take-away" consumption, since the preparation of the food products does not require the use of a fully equipped kitchen. All that is needed is a normal food heating device, such as a conventional oven or a microwave oven.

    [0054] Advantageously, by suitably selecting the level of moisture in the first food product, for example a predetermined sauce, the package can cook filled or unfilled pasta initially contained in the second container.

    [0055] Advantageously, a package according to the invention prevents the risk of the consumer getting dirty during the food product preparation step.

    [0056] Advantageously, a package according to the invention can preserve and cook "fresh" food products.
