Reversible lid (1) for a storage or reheating canister, comprising a first (2) airtight attachment means designed to cooperate with an upper edge (4) of a container (5) when the lid (1) is arranged along a first direction on the container (5) and a second (3) airtight attachment means designed to co
Reversible lid (1) for a storage or reheating canister, comprising a first (2) airtight attachment means designed to cooperate with an upper edge (4) of a container (5) when the lid (1) is arranged along a first direction on the container (5) and a second (3) airtight attachment means designed to cooperate with said upper edge (4) of the container (5) when the lid is arranged in the reverse direction on the container (5), characterized in that the lid (1) comprises a two-way steam release mechanism (10), connecting the two opposite surfaces of the lid, and in that said two-way release mechanism (10) allows a flow to pass between the two surfaces of the lid (1) when the pressure difference between the two surfaces is greater than or equal to a value (P0), particularly when reheating food in a microwave oven.

1. Reversible lid (1) for a storage or reheating canister comprising a first (2) airtight attachment means designed to cooperate with an upper edge (4) of a container (5) when the lid (1) is arranged along a first direction on the container (5) and a second (3) airtight attachment means designed to
1. Reversible lid (1) for a storage or reheating canister comprising a first (2) airtight attachment means designed to cooperate with an upper edge (4) of a container (5) when the lid (1) is arranged along a first direction on the container (5) and a second (3) airtight attachment means designed to cooperate with said upper edge (4) of the container (5) when the lid is arranged in the reverse direction on the container (5), the lid (1) having a portion in relief that can be oriented toward the interior of the container (5) to form with said container a first (6) closed interior space with a first (8) volume, or oriented toward the exterior of the container (5) to form with said container a second (7) closed interior space with a second (9) volume, separate from the first (8) volume, characterized in that the lid (1) comprises a two-way steam release mechanism (10) connecting a first surface of the lid and a second opposite surface of the lid, and in that said two-way release mechanism (10) allows a flow to pass between the first surface and the second opposite surface of the lid (1) when the pressure difference between the first surface and the second opposite surface is greater than or equal to a value (P0), particularly when reheating food in a microwave oven, wherein the two-way steam release mechanism comprises a first cover fastened to the first surface of the lid and a second cover fastened to the second opposite surface of the lid,wherein the lid comprises a flange extending therefrom to at least a height of the first and second covers such that the flange surrounds the first and second covers and the first and second covers are tightly mounted within the flange,wherein the two-way steam release mechanism (10) comprises: a first (11) one-way valve that allows a flow of steam to pass through when the pressure difference between a first surface and a second surface of the lid is greater than or equal to a value (P0), and that is airtight when the pressure difference between the first and the second surfaces of the lid is less than P0; anda second (13) valve, positioned opposite the first (11) valve, which allows a flow of steam to pass through when the pressure difference between the second surface and the first surface of the lid is greater than or equal to a value (P0), and that is airtight when the pressure difference between the second and the first surfaces of the lid is less than P0,wherein the first (11) valve comprises the first cover and one or more primary channels (16) passing through the lid (1), said first cover is fastened onto the first surface of the lid by a first (40) fastening means, and it covers entirely and in an airtight manner the one or more primary channels (16), and starting from Pressure P0 and above, said first cover warps under the effect of a flow that circulates in the one or more primary channels (16); and the second valve comprises the second cover and one or more secondary channels (18) passing through the lid (1), said second cover is fastened onto the second opposite surface of the lid (1) by a second (41) fastening means, and it covers completely and in an airtight manner the one or more secondary channels (18), and starting from Pressure P0 and above, said second cover warps under the effect of a flow circulates in the one or more secondary channels (18), andwherein the first (40) fastening means and the second (41) fastening means are assembled into a shared fastening means that comprises a central opening (19) that passes through the lid (1) from one side of said lid to the other and in which a central hub (20) is tightly mounted, which fastens the first cover and the second cover together, and the first cover is an airtight cover on the one or more secondary channels (18) and the second cover is an airtight cover on the one or more primary channels (16). 2. Reversible lid (1) described in claim 1, wherein the two-way steam release mechanism (10) is airtight when the pressure difference between the two surfaces of the lid is lower than the value (P0). 3. Reversible lid (1) described in claim 1, wherein the two-way steam release mechanism (10) is designed to ensure a watertight seal. 4. Reversible lid (1) described in claim 1, wherein the first cover comprises one or more primary through-holes (21) that are positioned opposite the one or more secondary channels (18), and the second cover comprises one or more secondary through-holes (22) that are positioned opposite the one or more primary channels (16). 5. Reversible lid (1) described in claim 4, wherein the one or more primary channels (16) or the one or more secondary channels (18) comprise a shoulder (150, 151) that goes up into the one or more primary through-holes (21) or into the one or more secondary through-holes (22) so as to increase the effectiveness of the airtight seal by limiting the passage of water between the first and second covers and the lid (1). 6. Reversible lid (1) described in claim 1, wherein the lid (1) comprises a domed area (25) on which the first and second covers are positioned under tension so as to prevent flows from passing through. 7. Reversible lid (1) described in claim 1, wherein the first and second covers are made of one of silicone or thermoplastic elastomers (TPE). 8. Reversible lid (1) described in claim 1, wherein the first and second covers comprise, on their surface that is in contact with the lid (1), a mirror-polished finish designed to increase the effectiveness of the airtight seal of the valves (11, 13), and the portion of the lid (1) in contact with the surface of the first and second covers may or may not also comprise a surface with a mirror-polished finish. 9. Reversible lid (1) described in claim 8, wherein the first (2) airtight attachment means and the second (3) airtight attachment means comprises a flap (27) positioned on the perimeter and the exterior of the lid (1) and that comprises a first (28) sealing groove located on top of the flap (27) and a second (29) sealing groove located below the flap (27) and the first (28) and the second (29) grooves have a U-shaped profile. 10. Reversible lid (1) described in claim 1, wherein the first cover and/or the second cover comprises at least one plug (200) sized to be inserted into the one or more primary channels (16) and/or into the one or more secondary channels (18). 11. Storage or reheating canister (100) comprising a lid (1) described in claim 1, and a container (5) that comprises an upper edge (4) that cooperates with the airtight attachment means (2, 3) of the lid (1), wherein the upper edge (4) has an oblong profile that is inserted into the first (28) sealing groove to form the first (6) interior space or into the second (29) sealing groove to form the second (7) interior space. 12. Storage or reheating canister (100) described in claim 11, wherein the canister (100) comprises a cap (101) with a free edge (102) that cooperates with the first (28) sealing groove or with the second (29) sealing groove, so as to form an airtight interior space.
