Description

CONTAINER FOR COOKING, STORAGE AND/OR TRANSPORTING DISHES

DESCRIPTION

Field of application

This invention? generally applicable to the technical sector of food containers, and particularly has as its object a container capable of being used for cooking food, in particular in the microwave, and/or for storing food, in particular in the refrigerator, and/or for the transport of cooked dishes and/or for the use of such dishes.

Does the present invention also concern? a method for cooking food using such a container.

State of the art

Cooking or preparation processes of dishes which require cooking them in a closed environment are known. A well-known typology of this cooking? the so-called ?vasocooking?. In this procedure the dishes are placed inside a closed glass container, and are subsequently heated using known techniques, for example in a ?bain-marie? or microwave.

For this purpose, glass containers are normally used, such as Bormioli Fido, IKEA Korken, Le Parfait Preserve, Kilner or Weck jars. These jars have a base, a lid, a gasket placed between them and a lever closure of variable shape, made of metal. When the internal pressure increases during cooking, the seal gives way, allowing air to escape.

Drawback of such containers? that of not allowing control of the internal pressure and therefore of the cooking process. Furthermore, the pressure to which the gasket yields? completely random and varies from one container to another.

Furthermore, in these known containers the internal pressure deforms the gasket in a radial direction, compromising its functioning over time. In other words, the pressure to which the hermetic closure of the same container yields is not only ? random, but variable over time.

Another drawback of these containers? that of making it necessary to heat the same container in order to be able to open it after the same? been stored in the refrigerator, that is? when the internal pressure ? lower than the external one. This procedure compromises the food inside the container. Furthermore, this procedure also affects the temperature of use of the dishes which cannot be consumed cold.

Another drawback of these containers? that of not being usable in some situations, for example when there? the risk of breakages such as during transport or use in public places.

Presentation of the invention

Purpose of the present invention? that of at least partially overcoming the drawbacks noted above, making available a container for cooking and/or storing and/or transporting food having highly functional characteristics.

Another purpose of the invention? provide a container for cooking and/or storing and/or transporting food that allows the cooking pressure to be controlled.

Another purpose of the invention? provide a container for cooking food in the microwave.

Another purpose of the invention? make available a container for cooking and/or storing and/or transporting food that allows its use in public places such as bars, restaurants or similar.

Another purpose of the invention? provide a container for cooking and/or storing and/or transporting food that maintains its performance unaltered over time.

Another purpose of the invention? provide a particularly safe container for cooking and/or storing and/or transporting food.

Another purpose of the invention? make available a container for cooking and/or storing and/or transporting food that allows it to be opened without the need? to heat the container.

Another purpose of the invention? provide a container for cooking and/or storing and/or transporting food that allows the internal pressure to be varied during the cooking phase of the food.

Another purpose of the invention? provide a container for cooking food using different culinary processes.

These purposes, as well as? others that will appear more? clearly below, they are reached by a container for cooking and/or preserving food in accordance with what is described, illustrated and/or claimed here.

Detailed description of some favorite implementation examples

With reference to the cited figures, a container 1 is described which is particularly suitable for the conservation and/or preparation and/or transport and/or use of food, as better explained below.

In particular, container 1 can be particularly suitable for heating a dish, for example to cook it, and for subsequently cooling it, for example to bring it back to room temperature and continue cooking or to store it in the refrigerator.

Essentially container 1 can? comprise or be made up of a base 20 and a lid 30. The latter can be mutually coupled to form the container 1.

Conveniently, container 1 can comprise gasket means 40, for example an elastomeric gasket, intended to remain interposed between the base 20 and the lid 30 and means 50 to removably retain the lid 30 and the base 20 mutually so as to form a closed container 1.

Preferably, but not exclusively, the base 20 and the lid 30 can be made of polymeric material. Preferably, the means 50 can also be made of polymeric material. More? preferably, container 1 can? be entirely made of polymeric material.

Preferably, this polymeric material can be copolyester or polypropylene used as is or could it be? be copolyester or polypropoylene filled with glass fiber or glass spheres or a mineral filler, for example talc.

Possibly, this material will be able to be polycarbonate or PET. Possibly, this material will be able to be recycled. For example, the base 20 and/or the lid 30 can be made of recycled PET.

Preferably, the material is of the type suitable for food contact.

Thanks to these characteristics, the container 1 itself will be able to be thermally insulating. In this way, unlike other materials such as glass, advantageously, the user will be able to handle container 1 after cooking.

Furthermore, in the case of preparing dishes by microwave cooking, the microwave oven will be able to act directly on the food without heating the container 1. In this way the container can not be an additional source of heat for the dishes, as happens with glass jars.

In this way, advantageously, the container 1 does not heat the food but only the action of the microwave allowing greater precision in the preparation of food.

The use of polymeric materials to make the container 1 in accordance with one or more? of the embodiments described below, will you be able to therefore allow the use of the same container 1 for the preparation of the dishes (for example by microwave cooking), for their conservation (for example in the refrigerator) and/or for the transport of the same and/or for the use of the same .

Furthermore, the container 1 made of polymeric material can allow the use of the same also in particular situations such as public places or similar where by law? The use of dangerous dishes such as glass containers is prohibited.

Furthermore, thanks to this feature, container 1 can be particularly safe and can can also be used by children.

Furthermore, container 1 can be washed in the dishwasher.

As better explained below, can the base 20 and the lid 30 be movable between a configuration in which they are distal and the container 1? open, and a configuration in which they are proximal and the container 1 is closed. In any case, the base 20 and the cover 30 can be operationally coupled together in the closed configuration in a different way depending on the embodiments.

The means 50 may therefore be different depending on the configuration of the base 20 and the cover 30. Optionally, the means 50 may also be made of polymeric material.

Preferably, container 1 can have a substantially box-like shape with a base wall 3 and a substantially flat opposite upper wall 4 and a side wall 5 placed between the base and upper walls 3, 4 and substantially perpendicular to the latter.

Preferably, as shown in the attached figures, the side wall 5 can be substantially continuous.

Possibly, the side wall 5 could preferably be free of edges. In this way, advantageously, you can prevent the container from damaging bags or other containers in the vicinity? of the same.

According to a particular aspect of the invention, when the lid 30 and the base 20 are in a proximal position and the container 1 is closed, the latter will be able to be mobile between a configuration in which ? hermetically sealed and a configuration in which ? closed in a non-hermetic way, that is? could? be allowed a small passage of air from inside to outside of container 1, or vice versa.

In this text this last configuration is defined as ?not hermetically closed? as the container 1 in this configuration will be able to? prevent food from spilling out and/or dirt from entering container 1 and at the same time being able to allow the passage of air.

Conveniently, container 1 can comprising sealing means 100 configured to allow the passage from the hermetically closed configuration to the non-hermetically closed configuration so that the internal pressure of the container 1 does not exceed a predetermined threshold value. In other words, the means 100 could be means for controlling the internal pressure of the container 1.

It is understood that the internal pressure could be directly linked to the internal temperature. Therefore, by acting on the pressure control you can? in fact act on the control of the internal temperature of the container and therefore of the cooking temperature. For example, the threshold pressure value could? correspond to a maximum temperature value.

Preferably, the means 100 can also be made of polymeric material. Possibly, as better explained below, the means 100 may be made entirely or partially of rubber.

Conveniently, the means 100 may be configured to allow automatic movement between the hermetically closed configuration and the non-hermetically closed configuration when the pressure inside the container 1 is ? equal to or greater than the predetermined threshold value.

Thanks to this characteristic, during use, when the pressure inside the container 1 exceeds the threshold value, for example by heating the dishes inside the hermetically closed container 1, the means 100 will automatically be able to allow the air to escape.

In this way, advantageously, you can prevent the pressure inside container 1 from exceeding the threshold value.

Preferably, this threshold value will be able to be predetermined. In this way, advantageously, it will be possible to prepare dishes according to recipes which require not to exceed a predetermined pressure value during cooking.

Furthermore, possibly this threshold value could be predetermined by the user. In this way, the user will advantageously be able to selectively predetermine the threshold value depending on the cooking method of the dishes you prefer.

Appropriately, in case they are considered a plurality? of container 1 equal to each other, these will all have the same pressure threshold value. On the other hand, even by reusing the same container 1 this will be possible. keep its predetermined threshold value unchanged over time.

Preferably the predetermined threshold value of the internal pressure will be able to be between 0.05 bar and 1 bar, more? preferably between 0.05 bar and 0.4 bar. In this text, the threshold pressure value is ? understood as the difference between internal pressure and external pressure.

In other words, the internal pressure could be greater than the external one by a value between 0.05 bar and 1 bar, (as happens for example when heating dishes in the microwave) or the external pressure could be greater than the internal one by a value between 0.05 bar and 1 bar (as happens for example when cooling dishes in the refrigerator).

Conveniently, the means 100 can be configured to retain the lid 30 and the base 20 in a closed position and at the same time allow a small reciprocal movement of the same between the configuration in which the container 1? hermetically closed and the lid 30 and the base 20 are proximal, and the configuration in which the container 1 is closed non-hermetically and the cover 30 and the base 20 are detached to form a cavity 101 which allows the passage of air.

More? in detail, the closed configuration will not be hermetically sealed? be achieved by a small detachment of at least one of the lid 30 and the base 20 from the gasket 40. In other words, the lid 30 and the base 20 can be mobile between a proximal position in contact in which they are both abutting against the gasket 40 so as to prevent the passage of air through them (hermetically closed configuration) and a detached configuration in which at least one of the lid 30 and the base 20 can be slightly spaced from the gasket 40 to form a cavity 101 to allow leakage of air (non-hermetically closed configuration).

Conveniently, the separation between the cover 30 and the base 20 in the non-hermetically closed configuration, i.e. the cavity 101, could? be relatively small, preferably less than a millimetre, so as to avoid the escape of food and/or the entry of dirt from/into the container 1 and at the same time allow the passage of air. Preferably, the cavity 101 will be able to be approximately 0.1-0.2 mm.

Conveniently, the means 100 may further be configured to promote the return of the lid 30 and the base 20 from the non-hermetically closed configuration to the hermetically closed configuration once the internal pressure of the container 1 ? lower than the predetermined threshold value. Will the 100 vehicles be able to do this? define a constraint between the lid 30 and the base 20 of a "yielding" type, that is? a bond that ?gives? at a certain force.

The lid 30 and the base 20 can normally be forced closed by the means 100 so as to ensure their adhesion with the gasket 40 and therefore the hermetic seal of the container 1, and at the same time they can ensure the return of the lid 30 and of the base 20 abutting with the gasket 40 once the pressure returns to a value lower than the threshold value.

The means 100 having the characteristics described above can therefore have different configurations. Preferably, the means 100 may be elastic so as to deform elastically upon detachment of the lid 30 and the base 20 and at the same time promote their return towards the hermetically closed configuration of the container 1.

The lid 30 can? therefore include at least an operational portion 31 while the base 20 can comprise a corresponding at least one operational portion 21. The operational portions 21, 31, once the container is in the closed position, they may be in correspondence, preferably facing each other. The transition of the cover 30 and the base 20 from the hermetically closed configuration to the non-hermetically closed configuration will be possible. correspond to the moving away or closer of the operating portions 21, 31 and consequently to the deformation of the elastic means 100.

As better explained below, the elastic means 100 can be configured so that the internal pressure of the container 1 corresponds to a predetermined deformation thereof. In this way, depending on the configuration (shape, significant dimensions, material or hardness) of the elastic means 100, they will be able to allow the detachment of the operational portions 21, 31 only when the pressure inside the container 1 reaches the predetermined threshold value with the advantages listed above.

Furthermore, as better specified below, the deformation of the elastic means 100 when passing from the hermetically closed configuration to the non-hermetically closed configuration is ? predetermined so that they always remain within the elastic limit of deformation and allow the characteristics to be kept unchanged over time. Thanks to this feature, the same 1 container can be reused over time while maintaining its pressure threshold value unchanged.

Some advantageous embodiments of the means 100 configured to form the cavity 101 by mutual movement of the cover 30 and the base 20 will be described below.

According to a first embodiment of the container 1 schematically illustrated in the figures from FIG. 7A to FIG. 9B, the means 100 may include or consist of one or more? clip 110 having a substantially ?C? shape with a pair of ends? 111, 112 opposite and a central area 113 interposed between the latter. The ends? 111, 112 may be intended to interact with portion 21 and portion 31 respectively.

Preferably, the clip 110 can? be made of polymeric material, for example polypropylene.

In particular, the clip 110 can be elastically deformable so as to allow the passage of portions 21 and 31 from the proximal configuration (FIG. 9A) corresponding to the hermetically closed configuration to the distal configuration (FIG.

9B) corresponding to the non-hermetically closed configuration, and promote the return from the distal to the proximal configuration.

In FIG.9A and in FIG. 9B ? shown is a clip 110 made in one piece that can be made? entirely deform elastically. It is understood that the clip 110 can include only the deformable portions 111 and 112 and a non-deformable central portion without thereby departing from the scope of protection of the present invention.

As schematically illustrated in FIG. 9B, when the portions 21, 31 are detached and the clip 100 deformed, it will be possible to form a cavity 101 to allow the air to escape.

Conveniently, the predetermined threshold pressure value will be able to be determined by the thickness S1 and/or length L1 of the clip 110 and/or by the material of the clip 110, i.e. from the properties? elastic of the latter.

For example, the 110 clip can? have a thickness S1 of approximately 1 mm, a length L1 of approximately 20 mm, and can? be made of polymeric material, for example polypropylene.

Can container 1? understand one or more? clip 110. For example, in FIG. 7B ? shown is a container 1 with a pair of clips 110.

Conveniently, the base 20 can? include a peripheral edge 22 which can? include the operational portion 21, while the cover 30 can? include a peripheral edge 32 which can? include the operational portion 31.

Thanks to this feature it will be possible to position the clips 110 in any position and in any number. Furthermore, can you? avoid the risk that the user positions the clip 110 in an incorrect area which compromises the functioning of the container.

Advantageously, the embodiment of the container 1 with the clips 110 can be particularly simple to use for the user.

According to a different embodiment of the container 1 schematically illustrated in the figures from FIG. 10A to FIG. 12B, the means 100 may comprise or consist of an elastic ring 120, preferably made of silicone or elastomer.

In this case, the portions 21 and 31 may have a substantially hemispherical shape so that when they are in proximity one of the other, the respective peripheral surfaces 23, 33 define a substantially circular seat 121 for the elastic ring 120.

Preferably, as schematically illustrated in FIG. 11, the portions 21, 31 may have an arched section so that the surface 23, 33 is substantially concave to define the concave seat 121 for the ring 120.

In this way, advantageously, you can avoid the accidental detachment of the ring 120 from the portions 21, 31, even in the event of an increase in the pressure inside the container 1.

Conveniently, the transition of the lid 30 and the base 20 from the hermetically closed configuration to the non-hermetically closed configuration will be possible. correspond to the passage of the operational portions 21, 31 from the proximal configuration (FIG. 12A) to the detached configuration (FIG.12B).

The 120 elastic ring can then deform elastically to allow this detachment of the portions 21, 31 and to promote their rapprochement.

As schematically illustrated in FIG. 12B, when the portions 21, 31 are detached and the elongated ring 120 can be form a cavity 101 to allow the air to escape.

Conveniently, as illustrated for example in FIG. 11, the predetermined threshold pressure value can? be determined by the thickness S2 and/or external diameter D2 of the ring 120 and/or by the material of the latter similarly to the clip 110.

It is understood that container 1 can comprising a pair of portions 21, 31 for a pair of rings 120 positioned on the same side of the container 1 (FIG. 10B) or on opposite sides (FIG. 13A). Possibly container 1 will be able to include four portions 21, 31 to house four corresponding rings 120 as schematically illustrated in FIG.13B.

Advantageously, the container 1 comprising the elastic rings 120 can be particularly long-lasting. In fact, the rings 120 can be configured so that the deformation expected in the pressure range normally used for the use of this container is within the elastic deformation range of the ring 120.

Furthermore, the container 1 made in accordance with this embodiment can be particularly safe since the rings 120 must necessarily be positioned in correspondence with the seats 120, thus avoiding the risk that the user does not position the rings 120 correctly.

Possibly, as schematically illustrated in the figures from FIG. 33A to FIG.34B, the ring 120 can be kept inside a rigid circular abutment element 131. In this case, when detaching the portions 21, 31 from the ring 120 it will be possible to deform to compress against the circular abutment element 131, for example against the internal surface 132 of the ring 131. It is understood that the substantially semicircular portions 21, 31 can be provided with the surfaces 23, 33 to define the seat 121 for the ?ring 120.

In addition to the advantages in terms of safety described above, thanks to the presence of the circular contact surface 132, pressure control will be possible. be particularly fine.

For example, with reference to this embodiment, the ring 120 can have a thickness S2 of about 5 mm, a diameter D2 of about 12 mm, and can? be made of rubber. In this case depending on the hardness of the rubber you can? vary the pressure threshold value. For example, considering 120 rings of this shape and size, but made of different materials, using 30ShA rubber the threshold value could be be 0.12bar, using 50ShA rubber the threshold value can? be 0.18 bar, using 75ShA rubber the threshold value can? be 0.26 bar.

According to a different embodiment illustrated for example in FIGS. 15A and 15B, 18A and 18B, and FIG. 20A, the means 100 may comprise or consist of at least one pin 130. Preferably this pin 130 may be made of polymeric material, for example elastomer or silicone.

Appropriately, could a rigid connection element 131 may be provided having a first portion 132 and a second portion 133 opposite and spaced from the portion 132. In operation, the portion 21 and the portion 31 may remain interposed between the portions 132 and 133 of the connection element 131 .

In particular, the pin 130 can be placed between the portions 31 and 132 so that the detachment of the base 20 and the cover 30 upon passage from the hermetically closed configuration to the non-hermetically closed configuration, i.e. the removal of portions 21 and 31 could? correspond to the bringing of portion 31 closer to portion 132, with the consequent compression of the pin 130 placed between them.

In other words, unlike the embodiments described above, the means 100 will be able to deform elastically due to compression when the base 20 and the cover 30 are detached.

As schematically illustrated in FIG. 15A and FIG. 15B, the connecting element 131 can? be essentially a closing lever and could? include a portion 134 that can be operated by the user to allow the closing/opening of the container 1.

It is understood that the distance between portions 132 and 133 could be such that the detachment of the portion 21 and 31 from the hermetically closed configuration to the hermetically closed configuration does not necessarily involve compression of the pin 130.

Advantageously in this embodiment the element 131 will be able to always remain attached to the lid 30 or to the base 20, for example by means of a hinge in an in-sequence manner? known. In this way, you can avoid losing element 131 during use or when washing in the dishwasher.

On the other hand, according to a different embodiment illustrated from FIG.16 to FIG.

18B, the connecting element 131 can? be a separate piece that can be removably coupled with the cover 30 and the base 20 in correspondence with the operating portions 21, 31. In particular, the element 131 can be comprising a hole 135, preferably substantially circular, and two portions 132, 133 located on opposite sides with respect to the hole 135.

Can hole 135? therefore be configured to accommodate the operational portions 21, 31 and the pin 130, while the portions 132, 133 can be spaced in such a way as to allow the movement of the same operational portions 21, 31 from the proximal position to the detached position.

Conveniently, element 131 will be able to include a seat to house the pin 130, for example a tubular seat, so that once the pin has been inserted into the seat, the latter partially occupies the hole 135 to remain interposed between the portion 21 and the portion 132, or between the portion 31 and portion 133, so that the movement of the operating portions 21, 31 from the proximal position to the detached position corresponds to the compression of the pin 130 in a similar way to what is described above for the lever 131.

In any case, regardless of the embodiment of the element 131, as for example schematically illustrated in FIG. 15B or in FIG. 18B, when the portions 21, 31 are detached and the pin 130 compressed it will be possible to form a cavity 101 to allow the passage of air, and in particular the escape of air from inside the container 1.

Conveniently, the distance between portions 132 and 133 could be such that when the portions 21 and 31 are detached, the latter are held by the portions 132 and 133 themselves. In other words, the latter can act as a stop for portions 21 and 31.

In this way, advantageously, the thrust due to the internal pressure will be able to be opposed by the element 131, while the pin 130 can? have the function of an elastic contrast element capable of promoting the return of the portions 21, 31 to the proximal position, that is? hermetically sealed container 1.

Could it be? furthermore, prevent the pin 130 from being compressed excessively, for example beyond the elastic deformation threshold, in the event of an excessive increase in pressure inside the container 1 or in the event of a particularly rapid increase in internal pressure.

Thanks to this feature you can preserve the pin 130, and therefore the means 100 and more? in general, container 1 can? maintain its characteristics over time.

Conveniently, the predetermined threshold pressure value will be able to be determined by the characteristics of the pin 130, for example by the diameter D3 of the pin 130 and/or by the material of the latter similarly to the clip 110 and/or the ring 120.

For example, the 130 pin can? have a D3 diameter of approximately 6 mm, and can? be made of elastomer or silicone.

According to a particular aspect of the invention, it may be provided a kit including a plurality? of pins 130 made of different materials so as to have a different elastic resistance, and therefore, once positioned in the seat 135 the means 100 can have a different maximum pressure threshold value.

Thanks to this feature, the same container 1 can be suitable for the preparation of dishes with a different pressure threshold value.

Furthermore, after a lot of use or in case of damage, you can simply replace the pin 130 without the need? to replace other parts of the container 1.

It is understood that plurality? of 130 interchangeable pins you can? be foreseen both with the embodiment of FIG. 15A and FIG. 15B of the element 131 which is the embodiment of FIG.18A and FIG.18B.

On the other hand, a plurality may be foreseen? of clips 110 having different thickness and/or material or a plurality? of elastic rings 120 having different thickness and/or material so that they allow the detachment of the base 20 and the cover 30 at a different threshold pressure with the advantages described above.

Is it understandable that it could? therefore a kit including container 1 and a plurality of of pins 130 or elastic rings 120 or clips 110 selectively, alternatively and removably coupled with the connecting element 131 or with the base 30 and/or cover 20.

Thanks to these characteristics, container 1 can be particularly versatile. Conveniently, in the embodiments illustrated in the figures from FIG. 7A to FIG.

20B wherein the container comprises the elastic means 110, 120 or 130, the seal 40 may be configured so as not to deform when the pressure increases. In fact, in this last case the means 100 will be deformed (in a different way depending on the configuration) while the gasket 40 will be able to deform. do not be deformed. In this way, when the portions 21 and 31 are detached, it will be possible to form the cavity 101.

In other words, in these embodiments described above, the gasket 40 can have any shape. For example, could have a flat shape (FIG. 9A) or circular shape (FIG.12A).

Possibly, at least one of the edges 32 will be able to include a seat 38 for the gasket 40 as for example schematically illustrated in FIG.5A and FIG.6A.

Thanks to this feature, the 40 gasket can easily be positioned correctly by the user

Furthermore, advantageously, the gasket 40 can remain in position during use, preventing it from coming out laterally, in particular when detaching and reattaching the cover 30 and the base 20.

For example, in the case of heating and then cooling, the gasket 40 ? solicited first from the inside outwards and then from the outside towards the insides. Can seat 38? then allow the gasket 40 to remain in position during both operating phases.

Possibly, the gasket 40 could? have a particular shape as illustrated for example in FIG. 19B and 20B. This last configuration, and its advantages, will be? better described below.

Regardless of the shape of the gasket 40, preferably, one of the edges 22 will be able to be flat so that the gasket 40 rests against a regular surface. With ?plan? does it mean that the flat surface of the edge can? have depressions of the order of a tenth of a millimetre. In this way, the working tolerances of the gasket 40 can be particularly reduced and a small detachment of the cover 30 and the base 20 can occur. correspond to the formation of the cavity 101.

In fact, in that case, isn't it? It is necessary to excessively compress the gasket 40 against the edges 22, 32 and you will be able to at the same time ensure that the gap 101 does not form at the desired threshold pressure.

According to a further embodiment, the means 100 can be configured so that the passage between the hermetically closed configuration and the non-hermetically closed configuration does not correspond to the mutual separation of the cover 30 and the base 20.

In other words, when switching from the hermetically closed configuration to the non-hermetically closed configuration, it will be possible to form the cavity 101, but the cover 30 and the base 20 will be able to keep the mutual distance d2 unchanged.

Conveniently, as schematically illustrated in the embodiments in the figures from FIG. 1 to FIG. 6B, the gasket 40 can be used? deform elastically when the pressure inside the container 1 exceeds the predetermined threshold value, forming the gap 101 between the boron 32 of the lid 30 and the edge 22 of the base 20. In other words, the gasket 40 will be able to define the means 100. Preferably, the deformation of the gasket can? correspond to a radial expansion.

Similarly to what is illustrated above for the means 100, the shape, hardness and thickness of the gasket 40 can be determine the pressure threshold value so that also in this case this value is predetermined.

In particular, the 40 gasket can? be configured to have a dimension, and in particular a thickness, such as to occlude the gap 102 between the edge 22 and the edge 32 when the latter are in the hermetically closed configuration so as to form the hermetic seal of the container 1.

Conveniently, when the pressure inside the container 1 reaches a predetermined threshold value, the gasket 40 will be able to deform, preferably thin, that is? decrease the thickness, so as to form the gap 101 between the edges 22, 32 and therefore allow the air to escape.

In other words, the 40 gasket can? be configured to elastically vary its thickness when the threshold pressure value is exceeded from an operating position in which it has an initial thickness such as to occlude the interspace 102 to create the hermetic seal between the edges 32, 22, defining the configuration hermetically closed, to an operating position in which it has a thickness lower than the initial thickness to form the cavity 101 defining the non-hermetically closed configuration.

Advantageously, depending on the shape, hardness and thickness of the gasket 40 it will be possible to predetermine the maximum pressure threshold value at which this gap 101 is formed.

In other words, the 40 gasket can? act in a similar way to the ?yielding constraint? described above, that is? can you? deform when an internal threshold pressure of container 1 is reached.

The gasket 40 can? have a substantially circular cross-section shape as for example illustrated in FIG. 5A and 5B, or oval as illustrated for example in FIG. 6A and 6B, or, preferably, could? have a particular shape as illustrated in the figures from FIG.2A to FIG.3D.

In any case, as illustrated for example in the figures FIG. 2A, FIG. 2B and FIG. 20B, the edge 32, the edge 22 and the gasket 40 can be mutually configured so that the latter is interposed between the edges 22, 32.

Conveniently, the edges 22 and/or 32 may include at least one respective substantially planar surface 24, 34 intended to interact with the gasket 40. The surfaces 24, 34 may preferably be facing and spaced apart from each other, even more so? preferably substantially perpendicular to the side walls 5. Possibly, the edge 22 and/or 32 may be constituted by the planar surface 24 and/or 34.

According to a particular embodiment, the gasket 40 can present a portion 43 of greater thickness S3 and a portion 42 of lower thickness S4 so as to form a step. In other words, the 40 gasket can? have a substantially L-shaped section. In the present text, this particular shape of the gasket 40 will be called a molded gasket.

Conveniently, the edge 32 will be able to be substantially counter-shaped with respect to the gasket 40. For example, the edge 32 could? present a longitudinal seat 38 for the portion 43. In this way, the substantially vertical walls 38? of the seat 38, preferably a pair of walls 38? parallel and facing each other, they will be able to center the portion 43 and therefore the gasket 40.

Preferably, portion 43 can? be inserted by interference into the seat 38. Thanks to these characteristics, when closing the lid 30 and the base 20, the gasket 40 will be able to be positioned correctly between the edges 32 and 22. In this way, advantageously, it will be possible to prevent the user from positioning the gasket 40 incorrectly and therefore preventing the seal from being achieved.

Furthermore, in case of lateral thrust, that is? substantially orthogonal to the side walls 5 of the container, the gasket 40 can be held in position by the side walls 38? of headquarters 38 and at the same time will be able to? deform between the hermetically closed configuration (FIG. 2B) and the non-hermetically closed configuration (FIG. 2C) forming the cavity 101.

More? in detail, the edges 32, 22 may include a further operating surface 34?, 24? mutually facing and spaced apart. It is understood that these latter surfaces have 34?, 24? could possibly be continuous with the surfaces 24, 34. For example, the surfaces 24 and 24? may be continuous and define a single flat surface, while the surfaces 34? and 34 may have different distances from the respective surfaces 24 and 24?.

The surfaces 24 and 24? will be able to define the flat edge 22 of the base 20. Thanks to this characteristic, advantageously, the base 20 will be able to be simple and economical to make. Furthermore, advantageously, you can avoid the formation of dirt near the edge 22.

Portion 43 could? be placed between the surfaces 24 and 34, while the portion 42 can be placed between the surfaces 24? and 34?.

Conveniently, the distance between surfaces 24? and 34? could? be substantially equal to the thickness S4 of the portion 42, while the distance between the surfaces 24 and 34 could be substantially less than the thickness S3 of the portion 43.

In this way, when the base 20 and the cover 30 are brought closer together, it will be possible to compress only the portion 43 which will be able to? then determine the entity? of the hermetic seal. Compression can? therefore take place along the axis of the thickness S3 that is? the one corresponding to the quantities? more material.

On the other hand, advantageously, during radial expansion, it will be possible to deform the gasket 40 along its entire width, that is? both portion 43 and portion 42, that is? along the maximum length.

Thanks to these characteristics, it will be possible to use relatively hard gaskets which allow high precision in the formation of the cavity and therefore in the control of the internal pressure of the container 1.

Conveniently, the 40 gasket can? have a width substantially equal to the edge 22. In particular, the gasket 40 can be configured in such a way that the portion 42 remains flush with the edge 22, preferably with the edge 22 and the edge 32 so that the external surface of the side wall 5 is substantially continuous.

Thanks to this feature you can prevent dirt from entering in correspondence with the gasket 40.

Furthermore, thanks to the particular shaping of the gasket 40, when the lid is closed, a part of portion 42 could? remain visible from the outside giving the container a high aesthetic appeal.

Possibly, as shown in FIG. 3A, portion 43 could? include a lower protuberance 44 with a surface 44? intended to contact the surface 24, and an opposite upper protuberance 45 with a surface 45? intended to come into contact with the surface 34. The distance between the surfaces 45? and 44? could? define the thickness S3.

In this way, at the time of vertical compression, that is? substantially parallel to the side wall 5, following the closing of the lid 30 and the base 20 the protuberances 44 and 45 can be compressed so as to ensure the tightness of the gasket 40. In particular, thanks to the surfaces 45? and/or 44? convex, the force exerted by the respective edge 22, 32 when closing will be able to be concentrated in a 24/44 zone? and 34/45? particularly restricted.

What has been described above with reference to the variation of the predetermined threshold value as a function of the hardness, thickness and shape of the pin 130, clip 110 and/or ring 120, could be similarly valid for the gasket 40 described.

For example, by varying the material of the gasket 40 it will be possible to vary its elastic deformation and therefore its tightness and consequently the pressure threshold value with the advantages described above.

Possibly, could it? increase/decrease the difference between the distance between the surfaces 24 and 34 and the thickness S3 to vary the hermetic seal, i.e. to vary the threshold value of the pressure inside the container before the gasket 40 deforms.

Do you understand that it can? vary this threshold value in other ways, for example by varying the hardness of the gasket material itself.

In the figures from FIG.3A to FIG.3D ? schematically reported the behavior of the gasket in different operating phases: when the container 1? open and the gasket 40 ? kept in the seat 38 by interference (FIG. 3A), when the container 1 is hermetically closed and the portion 43? in contact with the smooth surface 24? (FIG. 3B), when container 1 is not hermetically closed and the portion 43? slightly spaced from the smooth surface 24? (FIG. 3C) and when container 1? vacuum and the pressure acts from the outside and the entire area 41 of the gasket 40 is in contact with edge 22 (FIG.3D).

It is also understood that the same results described above can be obtained by using a gasket consisting solely of portion 43, as schematically illustrated in the figures from FIG. 5A to 6B. In this case the gasket 40 could present a portion of high height S3 intended to be compressed with the advantages explained above.

In particular, one of the edges 22 and 32, preferably the edge 32, can not be completely flat and you can? be configured so that the surfaces 24? and 34? they meet (FIG.5B) or are spaced (FIG.6B) when closing.

On the other hand, if the planar portion 42 is present, in the event of internal depression, as for example happens when the hermetically closed container is cooled, advantageously the entire lower zone 41, i.e. both the portion 42 and the portion 43 will be able to adhere to the edge 22 ensuring a high hermetic seal.

Thanks to this feature, container 1 can be heated or used to cook dishes and can? then be cooled or stored in the refrigerator without there being passages of air from the outside to the inside, that is? maintaining the so-called ?empty?.

Regardless of the configuration of the gasket 40, the cover 32 will be able to include at least one longitudinal projection 39 intended to interact with the edge 22 inside the container 1.

Advantageously, this emphasis 39 will be able to promote the centering of the cover 30 and the base 20 and therefore allow the latter to be coupled correctly. Can container 1? therefore be particularly safe and easy to use.

Possibly, as shown in FIG.27 and FIG.28, it will be possible to be expected a pair of projections 39, 39? one internal and one external to the edge 22. The gasket 40 can? therefore remain interposed within the same projections 39 and 39?.

Thanks to this feature, in addition to promoting centering, it will be possible to form a closed seat 38 for the gasket 40 so that a small deformation of the latter or a small removal of the lid 30 from the base 20 corresponds to the formation of the cavity 101. In other words, the container 1 will be able to be particularly precise.

It is understood that the particular shaped gasket 40 described above can be used in the container 1 described above in which it deforms upon reaching a pressure threshold value to form the cavity 101, or it could be used. be used in different containers.

In particular, the shaped gasket 40 can be used in combination with the means 100 as illustrated for example in FIG. 19B in which container 1 can? include both the clip 110 and the shaped gasket 40 as shown for example in FIG. 20B in which container 1 can? include both the lever 131 with the pin 130 and the shaped gasket 40.

In this case, the gasket 40 can? not deform when the threshold value is reached as the base 20 and the container 30 can move apart, but it can allow you to obtain the advantages described above with reference to centering, resistance to lateral thrusts, and "vacuum" action.

As described above, the base 20, the lid 30 and the means 100, be they clips 110, rings 120 or pins 130 or the deformable gasket 40, can act as a valve designed to predetermine the maximum pressure inside the container 1.

In particular, thanks to what has been described above, and in particular to the means 100, the container 1 will be able to automatically switch from the hermetically sealed configuration to the non-hermetically sealed configuration. Furthermore, again advantageously, the container can automatically switch from the non-hermetically closed configuration to the hermetically closed configuration.

Again advantageously, container 1 can switch from the hermetically sealed configuration to the non-hermetically sealed configuration respectively once the predetermined pressure value and the internal pressure have been reached? lower than the predetermined threshold value.

According to a particular embodiment, for example illustrated in FIG. 27, container 1 can? comprising the base 20, the lid 30, a gasket 40 placed between the latter and closing means 50 configured to keep the container hermetically closed.

In this case the gasket 40 could have the function of maintaining as much as possible the hermetic seal of the container 1 is possible. Preferably, this container 1 will be able to understand the projections 39 and 39? so that the gasket 40 acts in a narrow seat. In this case, in fact, the gasket 40 could be particularly compressed when closing container 1 and will be able to adhere to the walls of the seat 38 to guarantee a high hermetic seal.

Preferably also in this embodiment the gasket 40 will be able to be the shaped gasket described above having the advantages described above with reference to centering, resistance to lateral thrusts both from inside and outside. Furthermore, the edge 22 will be able to be flat so that the seal of the gasket 40 is particularly high.

Unlike embodiments containing the means 100 for controlling the pressure, this embodiment does not allow predetermining the maximum pressure reached inside and/or ensuring that the internal pressure does not exceed a predetermined threshold value.

Regardless of the embodiments described above, the joining means 50 may be different both in shape and type. Preferably, but not exclusively, they can include at least one hinge 51.

Optionally, the joining means 50 may be different depending on the type of means 100, for example depending on the number of clips 110 and/or rings 120 and/or elements 131.

For example, in the embodiments of FIG. 7A - FIG. 7B, FIG. 10A - FIG. 10B, FIG.

14A - FIG. 14B - FIG. 14C, of FIG. 16, FIG. 21 and FIG. 23A, the means 50 may include a hinge 51 located on the opposite side of the container 1 with respect to the clips 110, the elastic rings 120 and the element 131 respectively. The embodiments of the container 1 of FIG.4D and FIG.21, they may also include a hinge 51.

On the other hand, as schematically illustrated in the embodiments of the figures FIG. 4A, FIG. 23A and FIG. 27 and FIG. 31 the joining means 50 may comprise male and female elements 52 which can be mutually snap coupled.

Possibly, as schematically illustrated in FIG. 31, the base 20 could? include a protuberance or a concave portion 54 while the lid 30 can? include a counter-shaped portion 55 with respect to the protuberance 54, for example a convex portion, so as to allow mutual snap engagement. Furthermore, this configuration of the vehicles 50 will be able to be particularly suitable for use in containers 1 in which the means 100 allow the detachment of the base 20 and the lid 30.

Advantageously, the 55 portion can extend beyond the portion 54 so as to define a handle 134 which can be grasped by the user to allow easy coupling/uncoupling of the means 50 and therefore of the lid and the base.

Furthermore, the joining means 50 may include the means 100, as illustrated for example in the embodiments of FIG. 14A and FIG. 16, or the joining means 50 may be constituted by the means 100, as illustrated for example in the embodiments of FIG.13A and FIG.13B.

Regardless of the presence or absence of the means 100, the container 1 will be able to comprise valve means 70 suitable for selectively placing the interior of the container 1 in fluid communication with the external environment. It is understood that these means 70 may have different configurations without thereby departing from the scope of protection of the present invention.

Preferably, these means 70 can be selectively operated by the user. Thanks to this characteristic, when the internal pressure of the container 1 ? lower than that of the surrounding environment, by acting on the means 70 it will be possible? place the interior of the container in fluid communication with the external environment and therefore allow the subsequent opening of the container 1, for example by removing the base 20 and the lid 30.

Furthermore, advantageously, if the container 1 includes the means 100, the means 70 will be able to allow the same container 1 to be used with the means 100 to prepare dishes at atmospheric pressure. In other words, when the means 70 are open, the container 1 with the means 100 will be able to be in the non-hermetically closed configuration.

Conveniently, regardless of the presence of the means 100, the means 70 can be opened for a part of the preparation of the dishes and can be closed for a second part.

For example, the method of preparing dishes can? predict the cooking phase of a dish that releases a lot of water, for example courgettes. The preparation method can provide a phase in which the closed container 1 with the courgettes inside is positioned in the microwave for two minutes with the valve means 70 open (non-hermetically closed configuration) so that the excess water vapor escapes from the container. After 2 minutes it will be possible to close the valve means 70 (hermetically closed configuration) and it will be possible to proceed with cooking in the microwave. In this way the container 1 will be able to be in depression (so-called ?empty?) and could Furthermore, the courgettes are pasteurized.

Advantageously, if the container 1 includes the means 100, when the valve means 70 are closed, the former will be able to allow the passage from the hermetically closed configuration to the non-hermetically closed configuration as described above.

Possibly, according to a different method for preparing the dishes, the container 1 will be able to be placed in the microwave with the courgettes with the valve means 70 open. The latter can therefore remain open for the entire cooking time. Once the microwave cooking is finished you can? remove container 1 from it to cool it to room temperature. During this phase you can close the valve means 70 so that the container 1 goes into depression (so-called "vacuum") and possibly allows pasteurization.

When is the so-called ?vacuum? formed? the external pressure? greater than the internal pressure. Preferably, container 1 can therefore include the valve means 70 and the shaped gasket 40 (and the respective flat edges 22 and 32 shaped) with the advantages described above.

Preferably, the valve means 70 can be placed in correspondence with the lid 30. In particular, the lid 30 can include a seat 35 for the means 70. It is understood, however, that the means 70 can also be positioned in correspondence with the base 20 without thereby departing from the scope of protection of the present invention.

In the figures from FIG. 21 to FIG. 22B ? a particular embodiment of the means 70 which includes a rotating knob 71 is shown, while in the embodiment schematically illustrated in the figures from FIG. 23A to FIG. 24 and in FIG. 30 ? a different embodiment of the means 70 which includes a lever 75 is shown.

In both cases, the knob 71 and the lever 75 can be selectively operated by the user independently. known between a closed position in which they do not put the interior in fluidic communication with the external environment of the container 1 (Fig. 25A and FIG.

28A) and an open position in which they put the interior in fluid communication with the environment outside the container 1 (Fig.26A and FIG.29A).

With reference to the embodiment schematically shown in the figures from FIG. 25A to FIG. 26B, the lid 30 can? include a portion 35 with an operating surface 35? what could? understand one or more? through holes 36 to connect the inside of the container 1 with the external environment.

Preferably, the 35 portion can? be substantially cylindrical, while the knob could? be substantially discoidal. It is understood that the seat 35 and the knob 71 may have different shapes. Preferably the seat 35 and the knob 71 can be mutually shaped-counter-shaped so that the respective surfaces are in contact.

In any case, the knob 71 can comprising at least one operating surface 72 suitable for interacting with the holes 36 to selectively occlude the latter.

Conveniently, knob 71 can include a portion 73 which includes the operating surface 72. Advantageously, the portion 73 can be extend only for a portion of its lower surface 71? of the knob 71 so that the latter rotates between a closed position (FIG. 25B) in which the surface 72 is in correspondence with the holes 36, and an open position (FIG.26B) in which the surface 72 is not in correspondence with the holes 36 to form a cavity 70? between the surface 71? and the surface 35? so as to allow the passage of air through the holes 36 from the inside to the outside of the container 1 and/or vice versa.

Preferably, but not exclusively, there may be a plurality of of holes 36 so that the progressive rotation of the knob 71 corresponds to the progressive opening of pi? holes 36. In other words, advantageously, the rotation of the knob 71 will be able to allow you to regulate the inflow/outflow of air into/from container 1.

Possibly portion 35 could? include a central through hole 37. Knob 71 can include a circular gasket 74, for example an elastomeric ring, intended to remain interposed between the surface 71? and the surface 35? peripherally to the central hole 37 so as to occlude the latter to prevent the passage of air through it, and at the same time allow the rotation of the knob 71.

Conveniently, knob 71 can be inserted into the central hole 37, for example by means of a pair of clips.

Thanks to this feature you can avoid the disconnection of the knob 71 from the cover 30. Furthermore, advantageously, when the knob 71 is not coupled with the cover 30, the central hole 37 can allow food or liquids to be inserted into container 1, for example milk, oil, flavorings or similar.

Conveniently, the 35 portion can? have a substantially concave shape.

In this case, advantageously, the hole 37 can be in a central position so that the concave area 35 acts as an invitation for such added dishes or liquids.

With reference to the embodiment schematically shown in the figures from FIG.28A to FIG.29B, the lever 75 can include an operating surface 76 while the seat 35 can? include a corresponding operating surface 35? with one or more? through holes 36.

The operating surfaces 35? and 76 can be reciprocally shaped so that when the lever 75? in the lowered position (FIG. 28B) the surface 76 is in correspondence with the openings 36, while when the lever 75 is in the raised position (FIG. 29B) the surface 76? spaced by openings 36

Preferably, as particularly illustrated in FIG. 28B, the 75 lever can? include a gasket 77, for example an elastomeric ring, placed in correspondence with the surface 76 and intended to remain interposed between the surface 76 and the surface 35?.

In this way, when the leverage 75 ? lowered the gasket 77 could? surround the holes 36 (FIG. 28B) to prevent the passage of air between the container 1 and the outside, while when the lever 75 is raised, the gasket 77 can? be spaced by the holes and can? the passage of air through the holes 36 and therefore the entry/exit of air into/from the container 1 must be allowed.

Similarly to the above, also in this case it will be possible to provide a plurality? of holes 36 so that the progressive raising of the lever 75 corresponds to the fluidic communication of the inside of the container 1 with the outside through a greater number of holes 36.

It is understood that the valve means 70 may have different configurations without thereby departing from the scope of protection of the present invention.

According to a particular aspect of the invention, the valve means 70 may not protrude from the container 1. In particular, the valve means 70 in the closed position may be entirely housed in the seat 35 so as not to protrude with respect to the upper wall 4 of the container 1.

In this way, advantageously, the containers 1 can be easily stacked.

Possibly, regardless of what is described above, the container 1 will be able to include an RFID 80 TAG to allow traceability? of the container 1 itself and/or the contents.

Preferably, the RFID TAG 80 can be inserted inside the container 1 using the IML technique (in model labeling) in a way in itself? known.

From what has been described above, it is clear that the invention achieves the intended objectives.

The invention? susceptible to numerous modifications and variations, all falling within the inventive concept expressed in the attached claims. All the details may be replaced by other technically equivalent elements, and the materials may be different according to needs, without departing from the scope of the invention.

Even if the invention is has been described with particular reference to the attached figures, the reference numbers used in the description and in the claims are used to improve the intelligence of the invention and do not constitute any limitation to the claimed scope of protection.
