    [0001] BACKGROUND OF THE INVENTION The present invention relates generally to a food box for the preservation and reheating of foods. B.1513 REVERSIBLE COVER AND CONTAINER FORMING A VARIABLE VOLUME FOOD BOX The invention relates more particularly to a variable volume box which comprises a reversible lid adapted to the preservation and heating of food.
    [0002] Variable volume food boxes for food preservation are known and also aim to reduce the amount of air in the food storage space to reduce the airborne oxidation of food. Having a variable volume also makes it possible to store a larger quantity of food.
    [0003] For this purpose, these boxes include two bins, including a large bin and a smaller bin. The bins are constructed so that the smaller of the two bins can be placed inside the larger reversibly and in this stacking position, the smaller bin acts as a closing element for the larger bin . If the volume of food to be stored in the larger bin requires, the smallest bin can be reversed to meet this particular case, the storage volume of the box is then increased, and it is also used as a closure element for the largest bin. US4091953 discloses such a device. One of the disadvantages encountered in such a device relates to the case where a user wishes to heat directly in the microwave oven food contained in the box and this regardless of the closure configuration of the box. Indeed during a passage in the microwave, if the pressure inside the box exceeds a certain value, the closure system is no longer able to maintain the two tanks between them which has the effect of project one of the bins into the microwave. This comes from the impossibility of evacuating the steam in a controlled way. The present invention therefore aims to solve these problems mentioned above by proposing a variable volume box that is suitable for the preservation and heating of food, and this regardless of the closure configuration of the box. In order to achieve this objective, the invention relates to a reversible lid for a storage or heating box comprising first sealed fastening means intended to cooperate with an upper edge of a container when the lid is arranged in a first direction on the container and second sealing means for cooperating with the upper edge of the container when the lid is arranged in the opposite direction on the container, the lid having a raised portion which can be oriented towards the inside of the container to form with this last a first closed chamber having a first volume, or oriented outwardly of the container to form therewith a second closed chamber having a second volume, distinct from the first volume, characterized in that the lid comprises a bidirectional evacuation device vapor connecting two opposite sides of the lid and that the bidirectional evacuation device allows the passage of a flow between the two faces of the lid when the pressure difference between the two faces is greater than or equal to a value PO especially during the heating of a food in a microwave oven. An advantage provided by such a lid is that the closed box can pass into the microwave regardless of its volume and is therefore suitable for reheating food. According to one characteristic of the invention, the bidirectional steam evacuation device is airtight when the pressure difference between the two faces of the lid is less than the value P0. The advantage is to have an airtight volume in the box which makes it suitable for the preservation of a food. According to a characteristic of the invention, the bidirectional steam evacuation device is designed to ensure hermeticity to a water flow.
    [0004] The advantage is to have a box adapted to the storage of a food, whether liquid or solid, and that avoids leakage out of the box especially during transport if the box turns. According to one characteristic of the invention, the bidirectional steam evacuation device comprises a first unidirectional valve which passes a stream of vapor when the pressure difference between a first face and a second face of the lid is greater than or equal to one. value and which is sealed when the pressure difference between the first and the second face of the lid is lower PO, and a second valve, positioned in opposition to the first valve, which passes a flow of steam when the pressure difference between the second face and the first face of the cover is greater than or equal to a value PO and which is sealed when the pressure difference between the second and the first face of the cover is less than PO. The advantage is to have a lid that is suitable for heating and preserving food or liquids. According to a characteristic of the invention, the first valve is composed of a first cap and one or more primary channels passing through the cap, said first cap is held on one side of the cap by a first holding means and it covers completely and in a sealed manner the one or more primary channels and from and above the pressure PO, said first operculum deforms under the effect of a flow that circulates in the one or more primary channels, so as to allow the passage the flow of the first or second enclosure outwardly thereof by one or more primary channels and the second valve is composed of a second seal and one or more secondary channels passing through the cover, said second seal is held on the lid, on the opposite side to the first lid, by a second holding means, and covers completely and tightly one or more secondary channels and t from and beyond the pressure PO, said second cap deforms under the effect of a flow that flows in the one or more secondary channels, so as to allow the passage of the flow of the first or the second enclosure outwardly through one or more secondary channels. The advantage is to have a bidirectional two-valve discharge device 10 which operates in opposition and the two valves are positioned independently of one another. According to a feature of the invention, the first and second covers are positioned opposite one another and on either side of the cover, the first holding means and the second holding means are joined together into a common holding means which is constituted by a central opening which passes through the lid from one side of the latter and in which is mounted tightly a central hub which holds the first and second covers together, and the first The seal covers the one or more secondary channels and the second seal covers the one or more primary channels in a sealed manner. The advantage is to have a bidirectional two-valve evacuation device that operates in opposition and is combined. According to a feature of the invention, the first cap comprises one or more primary through holes that are positioned opposite one or more secondary channels and the second cap comprises one or more secondary through holes that are positioned opposite one or more primary channels. The advantage is to have two valves that work in opposition and that are combined to allow reheating and preservation of food in the box.
    [0005] According to a characteristic of the invention, the one or more primary channels or the one or more secondary channels comprise one or more shoulders that rise in the one or more primary through holes or in the one or more secondary through holes so as to increase the effectiveness of sealing by limiting the passage of water between the covers and the cover. According to a characteristic of the invention, the lid comprises a convex zone on which the lids are positioned in stress so as not to let flow.
    [0006] The advantage is to increase the tightness of the two valves. According to a feature of the invention, a flange which surrounds the caps is integrated on either side of the cover, so as to ensure a seal to any flow of the first or the second enclosure. The advantage is to increase the tightness of the two valves.
    [0007] According to one characteristic of the invention, the covers are made of silicone material or thermoplastic elastomers (TPE). According to a feature of the invention, the first and second sealing means are constituted by a tongue positioned on the periphery and on the outside of the lid, and the tongue comprises a first sealing groove placed above it. ci and a second shutter groove placed below the tongue; and the first and second grooves have a U-shaped profile. According to a feature of the invention, the covers comprise on their surface in contact with the cover, a mirror-polished finish which makes it possible to increase the sealing efficiency of the valves. and the portion of the lid in contact with the surface of the covers may or may not include a mirror-polished finish. The invention also relates to a storage or reheating box comprising a lid and a container which comprises an upper edge which cooperates with the sealing means of the lid. According to one characteristic of the invention, the upper edge has an oblong profile which is inserted into the first sealing groove to form the first enclosure or in the second sealing groove to form the second enclosure. The advantage is to increase the tightness of the drink when it turns over. According to a characteristic of the invention, the box comprises a cover comprising a free edge that cooperates with the first sealing groove or with the second sealing groove so as to form a sealed enclosure. The aims, aspects and advantages of the present invention will be better understood from the description given below of a particular embodiment of the invention presented by way of non-limiting example, with reference to the accompanying drawings in which: - Figure 1 is a perspective view of a box according to the invention; - Figure 2 shows a sectional view of a box in a first mode of closure and with a first embodiment of the steam evacuation device; - Figure 3 shows a sectional view of a box of a box in a second mode of closure and with the first embodiment of the steam evacuation device; FIG. 4 represents an exploded perspective view of the lid with a steam evacuation device in the first embodiment; - Figure 5 shows a sectional view of a box in the first mode of closure with a second embodiment of the steam evacuation device; - Figure 6 shows a sectional view of a box in the second closure mode with the second embodiment of the steam evacuation device; - Figure 7 shows a perspective view in section of the steam evacuation device in an alternative embodiment. As can be seen in FIG. 1, the invention relates to a lid 1 comprising a raised portion which is composed of a wall 1a, advantageously flat, and of one or more side walls 1b that surround the bottom wall to form a container for solid or liquid foods. As can be seen in FIG. 3, this cover 1 comprises a first fixing means 2 and a second fastening means which consist of a tab 27 positioned on the periphery and on the outside of the cover 1. More specifically, the tab 27 extends from the side wall lb and perpendicular to the outside of the cover 1. This tab 27 can be positioned substantially in the middle of the side wall 1b. In other embodiments of the positioning of the tongue 27, it can be positioned on the lower half of the side wall lb, or on the upper half of the side wall lb. Preferably it forms with the side wall lb a right angle. In other positioning variants, it forms with the side wall 1b an angle of between 1 and 89 ° with respect to the side wall 1b. In addition the first 2 and the second 3 fixing means comprise a peripheral wall 1c which is positioned at the outer end of the tongue 27.
    [0008] It extends parallel to the side wall 1 of the cover 1 above and below the tongue 27, so as to form a first 28 closing groove which is positioned above the tongue 27 and a second groove 29. shutter which is positioned below the tongue 27. On the peripheral wall 1c, handles 1d for gripping the cover 1 can be positioned.
    [0009] The first 28 and the second 29 shutter groove have substantially U-shaped profiles and are formed by, on one side the side wall 1 of the cover 1 and on the other side by the peripheral wall 1c of the tongue 27. The lid 1 is provided to be positioned on a container 5 which comprises for this purpose an upper edge 4. The upper edge 4 has an oblong profile. More precisely, this upper edge 4 is intended to cooperate with the first fixing means 2 or with the second fastening means so that the cover 1 can be reversibly positioned on the container 5 and thus form a storage box 100. variable volume according to the position of the lid 1 on the container 5. In addition to the lid 1 and the container 5, the box 100 for conservation or heating has a cover 101 which comprises a free edge 102 which cooperates with the first 28 groove shutter or with the second shutter groove 29 so as to also form a sealed enclosure.
    [0010] These first 2 fixing means and these second fixing means 3 are sealed, which means that air, steam or even liquids can not pass through these fastening means (2, 3). Similarly, these are not limited to the construction previously described but may also be magnetic fastening means, hook fastening means or any other means to ensure the desired function which is to maintain the lid 1, the container 5, and possibly the cover 101, together in a sealed manner and in different modes of closing the box 100. As shown in Figure 2, which shows a first mode of closure of the box 100, the lid 1 is positioned on the container 5 and the upper edge 4 is inserted into the first 2 fixing means constituted by the first 28 sealing groove to form a first closed chamber 6. The storage box 100 thus formed is waterproof. In this first mode of closure, the bottom wall 1a of the lid 1 extends towards the inside of the container 5 so that the bottom wall 1a is below the upper edge 4 of the container. This first closed enclosure thus makes it possible to receive, store and heat food and it defines a first food storage or reheating volume which corresponds to all the space that the food can occupy in this first closed enclosure. As can be seen in FIG. 3, which represents a second mode of closure of the box 100, the upper edge 4 is inserted into the second attachment means constituted by the second closure groove 29 to form a second closed enclosure. . In this configuration, the bottom wall 1 of the lid 1 extends outwardly of the container 5 and the bottom wall 1 of the lid 1 is then above the upper edge 4 of the container 5. This second closed enclosure 7 allows also to receive, store and heat food and it defines a second volume which corresponds to all the space that can occupy food in the second closed enclosure. The second volume is generally larger than the first volume and thus allows to contain a larger volume of food to be heated or stored. In addition, the lid 1 comprises a bi-directional steam evacuation device 10 which is made in a non-limiting manner according to a first embodiment or according to a second embodiment. According to the first or the second embodiment of the bidirectional steam evacuation device, visible in FIGS. 2 to 6, this is composed of a first valve and a second valve. The first valve 11 and the second valve 13 are positioned on the lid 1 and operate in opposition as will be explained later. In another alternative embodiment of the bidirectional steam evacuation device, not shown, the first valve and the second valve are positioned on the container.
    [0011] In both embodiments of the bidirectional steam evacuation device, the first valve is composed of a first cap positioned and held on one side of the lid 1. The first valve further comprises one or more primary channels 16 positioned under the first valve 11 and through the cover 1 from one side. On the face of the cover 1 where the first operculum is located, the one or more openings of these one or more primary channels 16 are completely covered and this in a sealed manner. In general, it will be understood by sealing that a liquid or gaseous flow can not pass or pass. In this case, the flow that passes through the one or more primary channels 16 is entirely stopped by the first seal 15 below a certain pressure PO exerted by this flow. The second valve 13 is composed of a second cap 17 positioned on the face of the lid 1 opposite to the first cap. The second valve 13 comprises one or more secondary channels 18 passing through the cover 1 from one side to the other. These one or more secondary channels 18 are different from the one or more primary channels 16, but these different channels (16, 18) are all opening through the lid 1. These one or more secondary channels 18 are completely covered in leaktight manner by the second 17 covers such that a liquid or gaseous flow that passes through the one or more secondary channels 18 is stopped by the second 17 operculum if the pressure exerted by this flow is lower than the pressure PO. In the context of the invention, the covers (15, 17) are circular discs which have a thickness of a few millimeters. In other embodiments of the lids (15, 17), their shapes may be square, rectangular or any other shape. The covers (15, 17) are made of silicone material or thermoplastic elastomers (TPE).
    [0012] In the first embodiment of the bidirectional steam evacuation device, visible in FIGS. 2 to 4, the second seal 17 is positioned and held in register with the first seal. In this way, the one or more secondary channels 18 passing through the lid 1 are covered in leaktight manner by the first operculum and the one or more primary channels 16 are then also covered in leaktight manner by the second operculum 17. In order that the flows can flow in the different channels, the first operculum comprises one or more through holes 21 primary. These are positioned in front of one or more secondary channels 18 to allow a flow to enter one or more secondary channels. In the same way, the second cap 17 comprises one or more secondary through holes 22 which are positioned in front of the one or more primary channels 16 and this in order to allow the flow to enter the one or more primary channels 16.
    [0013] As one or more secondary channels 18 are different from one or more primary channels 16, the one or more primary through holes 21 are offset from one or more secondary through holes 22. In an alternative embodiment of one or more primary channels 16 or one or more secondary channels 18 shown in Figure 7, these include one or more shoulders (150, 151). These shoulders (150, 151) are respectively in the one or more primary through holes 21 or in the one or more secondary through holes 22. The purpose of these shoulders (150, 151) is to increase the effectiveness of the seal by limiting the passage of water between the covers (15, 17) and the cover 1.
    [0014] Still in connection with FIGS. 2 to 4, and in order to maintain the first operculum and the second operculum 17 on the lid 1, a common fastening means is used which comprises a central hub. This central hub 20 is connected to the first cap 15 and the second cap 17 through a central opening 19 which is formed in the cover 1 and which opens on either side of the cover 1. The central hub 20 can be glued or welded to the first operculum or the second seal, for example by molding. The central hub 20 is tightly mounted in the central opening 19. The central hub 20 is substantially longer than the length of the central opening 19 such that a portion protrudes from said central opening 19 on the opposite side to the second seal 17. The portion of the central hub 20 protruding from the side opposite to the second seal 17 makes it possible to mechanically maintain the first cap with the second cap 17. This mechanical support can be done via clips 20a. The length of the central hub 20 can then be determined so as to have an assembly of the two lids (15, 17) in tension against the lid 1. In a variant embodiment not shown, the central hub 20 and the second 17 lid are removable. from each other and are retained by additional holding means, not shown. This holding means is preferably mechanical such as clips, but it is not limiting and it can also be magnetic. The lid 1 may also comprise a curved zone 25 on which the lids (15, 17) rest. This curved zone 25 rises on both sides of the cover 1 and as previously described, the first operculum and the second operculum 17 are positioned in tension on this curved zone 25. In this case, the one or more primary channels 16 and the one or more secondary channels 18 pass through the convex zone 25. The advantage of such a convex zone 25 is to reinforce the sealing of the valves (11, 13) to the flows. In addition to the convex zone 25, the lid 1 comprises a flange 26 which surrounds the lids (15, 17). This flange 26 extends from the cover 1 and reaches at least the height of the covers (15, 17). The covers (15, 17) are mounted tightly in the collar 26. As shown in Figures 2 and 3, the flange 26 is circular so as to match the circular shape of the covers (15, 17). The advantage of the collar 26 is that, combined with the convex zone 25, the sealing of the valves (11, 13) is reinforced. In the second embodiment of the bidirectional steam evacuation device, visible in FIGS. 5 and 6, the first valve and the second valve are not positioned in a screw and screw position and are dissociated. In this case, the first valve is always composed of a first cap and one or more primary channels 16 passing through the cover 1. The first cap is held on one of the faces of the cover 1 by a first means. and the first cap completely and tightly covers the one or more primary channels 16. The second valve 13 is also composed of a second cap 17 and one or more secondary channels 18 passing through the lid 1. The second cap 17 is held on the lid 1, on the opposite side to the first cap 15, by a second 41 holding means. The second cover 17 completely and tightly covers the one or more secondary channels 18. Whether in the first or in the second embodiment of the bidirectional steam evacuation device, the lids (15, 17) may comprise on their surface in contact with the lid 1, a surface with a mirror-polished finish intended to increase the sealing efficiency of the valves (11, 13). The portion of the lid 1 in contact with the surface of the covers (15, 17) may also include a surface with a mirror-polished finish.
    [0015] We will now describe the operation of the bidirectional steam evacuation device 10 in its first embodiment visible in FIGS. 2 to 4. As can be seen in FIG. 2, the box 100 is in its first closure mode, that is, that is, when the bottom wall 1 of the lid 1 is below the upper edge 4 of the container 5 and the box 100 thus forms the first closed chamber 6. As described above, the first closed enclosure 6 can receive, store and reheat food and it defines the first volume of food storage or reheating. This mode of closure is interesting when the volume to be stored or heated food is low and a user wants to reduce the volume of the box 100 to avoid the deterioration of food that occurs because of the air content in the storage volume. Foods to be stored or heated are therefore placed in the first enclosure. This first enclosure being closed and sealed, the food contained in the first storage or reheating volume will heat up and produce a flow of air or steam when the box 100 is placed in a microwave oven. operation. The bidirectional steam evacuation device is designed to vent this vapor outside the first enclosure. This evacuation of the flow outside the first enclosure occurs when an overpressure is created in the first enclosure. By overpressure it is meant that the pressure within the first enclosure is greater than the outside pressure. To restore a pressure balance, the flow must be evacuated outside the first enclosure. Overpressure is produced by heating the food or air contained in the first enclosure. The stream will first pass through the one or more secondary through holes of the second cap to access one or more primary channels. At the end of these one or more primary channels 16, the flow is then stopped by the first sealed operculum. Below the pressure PO, the flow remains blocked. When the pressure inside the first chamber reaches the pressure PO, then the first cap is deformed so as to allow the flow of the first chamber to flow outwardly thereof. At the same time, the second cover 17 is always positioned in tension against the cover 1 and is always sealed. It is obvious that in this mode of closure, the first 2 securing means makes it possible to maintain the lid 1 and the container 5 up to at least one internal pressure at the first 6 PO enclosure. In the case where the pressure PO is not reached, the bidirectional steam evacuation device 10 is also designed to ensure watertightness of the first enclosure when the foodstuff to be stored is, for example, liquid. By this is meant that the bidirectional vapor venting device is designed such that the liquid that rests on the bottom of the lid 1 will not seep through the bi-directional device and will not go into the first one. 6 enclosure, as long as the pressure inside the first enclosure does not exceed PO. This is due to the fact that on the one hand the first operculum is not deformed by the passage of the flow of the first chamber 6 towards the outside of the latter and on the other hand, the second 17 operculum is sufficiently rigid not to be deformed by the liquid that has entered the one or more secondary channels 18 and which therefore bears on the second 17 seal which thus retains its seal. Now in connection with FIG. 3, which represents the second mode of closure of the box 100, that is to say when the bottom wall 1 of the cover 1 extends towards the outside of the container 5, we will describe the operation of the bidirectional steam evacuation device 10 still in its first embodiment. In this situation, the bottom wall 1a of the lid 1 is then above the upper edge 4 of the container 5 and forms the second and second chambers.
    [0016] This mode of closure is interesting when a user must store a large volume of food. The bidirectional steam evacuation device 10 is also designed to evacuate a stream of vapor or air outside the second enclosure when it is overpressurized.
    [0017] In the same way as above, it is meant by overpressure that the pressure inside the second chamber is greater than the external pressure. To restore a pressure balance, the flow must be discharged outside this second enclosure. The stream will first pass through one or more primary through holes 21 of the first cap to access one or more secondary channels. At the end of these one or more secondary channels, the flow is then stopped by the second seal. Below the pressure PO, this flow remains blocked in one or more secondary channels. When the pressure inside the second chamber reaches this pressure PO, then the second cap is deformed so as to allow the passage of the flow of the second enclosure 17 towards the outside. At the same time, the first cover is always positioned in tension against the cover 1 and is always sealed. It is evident in this mode of operation that the second fixing means 3 can hold the lid 1 and the container 5 up to at least one internal pressure at the second 7 PO enclosure. In the case where the PO pressure is not reached, the bidirectional steam evacuation device 10 is also designed to provide watertightness of the second enclosure.
    [0018] This is due to the fact that the second cap 17 is not deformed by the passage of the flow of the second enclosure 7 towards the outside thereof. Referring to FIGS. 5 and 6, which show the second embodiment of the bidirectional steam evacuation device, the first valve and the second valve are offset relative to one another. In this case, the one or more primary channels 16 are no longer covered by the second cover 17 and the one or more secondary channels 18 are no longer covered by the first operculum.
    [0019] Thus when one is in the first closed position of the box 100, and beyond the pressure PO, the first valve will allow the flow to pass outside the first enclosure, in a first 12 direction of passage which is directed from the inside of the first enclosure to the outside. More precisely, the flow circulates in one or more primary channels 16 and, beyond the pressure PO, the first operculum deforms under the effect of the flow so as to allow the passage of the flow in the first direction of passage. At the same time, the second valve, positioned in opposition to the first valve, does not allow steam to pass outside the first enclosure in the first direction of passage. In this case, the flow does not even flow through one or more secondary channels. In the case now that the pressure in the first chamber is less than PO, the first seal of the first valve is not deformed and is sealed in the first direction of passage. In a second direction of passage, which is directed from the outside of the first chamber towards the interior thereof, the first seal is also sealed. In this case, the flow in the second direction of passage can not pass through the first valve.
    [0020] At the same time, it may be noted that water may possibly be positioned in the one or more secondary channels of the second valve, without the latter being able to deform the second cap. In this case, the flow in the second direction of passage can not pass through the second valve.
    [0021] In the closing mode of the box 100 of FIG. 6, the first valve, beyond the pressure PO, does not allow the flow to pass outside the second enclosure, in a third direction of passage. which is directed from the inside of the second enclosure to the outside thereof.
    [0022] The second valve 13, it allows the flow outside the second chamber 7 beyond the pressure PO in this third direction 12a passage. Below the pressure PO, the second valve 13 does not allow flow to flow in a fourth passage direction 14a opposite the third direction 12a of passage, that is to say directed from outside the second enclosure 7 towards the inside of it. The first valve, beyond the pressure PO, is impervious to any flow in the fourth passage direction 14a. As a result, the box 100 is suitable for the preservation of food.
    [0023] It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the embodiment of the invention described in the present description without departing from the scope of the invention defined by the appended claims. Thus, in an embodiment variant not shown, the cover may comprise a curved or spherical wall.
