The lid component is made of an air-impermeable material and is dimensioned and configured to be releasably attachable to the jar by the band and to seal the wide mouth opening of the glass jar in an air-tight manner. The lid component further comprises a one-way valve adapted to allow gas produced by a fermentation process occurring inside the jar to escape from the jar while, at the same time, prevent oxygen-containing air from entering the jar, when the lid component is releasably attached to the jar. ## Claims ### Claim 1 A lid component for use with a glass jar and band of a mason jar, the lid component being made of an air-impermeable material and being dimensioned and configured to be releasably attachable to the jar by the band and to seal a wide mouth opening of the glass jar in an air-tight manner, the lid component comprising: a one-way valve adapted to allow gas produced by a fermentation process to escape from the jar while, at the same time, prevent oxygen-containing air from entering the jar, when the lid component is releasably attached to the jar; and a sealing wall, wherein the one-way valve comprises a bottom opening, a top wall, and a peripheral side wall extending from the bottom opening to the top wall, the peripheral side wall defining a space and the top wall having at least one opening biased towards a closed position and movable to an open position when pressure inside the space exceeds atmospheric pressure by a threshold amount; wherein the sealing wall extends radially outwardly from the bottom opening; wherein the sealing wall is substantially flat; wherein the lid component has a height and a diameter; wherein the bottom opening has a bottom opening diameter; wherein the sealing wall has a sealing wall diameter that is equal to the diameter of the lid component minus the bottom opening diameter; and wherein the sealing wall diameter is at least two (2) times greater than the height of the lid component. ### Claim 2 (depends on 1) The lid component of claim 1, wherein the lid component is of unitary construction for ease of manufacture. ### Claim 3 (depends on 2) The lid component of claim 2, wherein the lid component is made of a flexible and resilient material. ### Claim 4 (depends on 3) The lid component of claim 3, wherein the material is silicone rubber. ### Claim 5 (depends on 1) The lid component of claim 1, wherein the top wall is tapered from the side wall. ### Claim 6 (depends on 1) The lid component of claim 1, wherein the sealing wall has a uniform thickness. ### Claim 7 (depends on 6) The lid component of claim 6, wherein the sealing wall has a thickness of about 1 to about 3 mm. ### Claim 8 (depends on 7) The lid component of claim 7, wherein the thickness is about 2 mm. ### Claim 9 (depends on 8) A fermentation kit comprising a lid component according to claim 8. ### Claim 10 (depends on 1) The lid component of claim 1 wherein the sealing wall has a diameter of about 8.5 cm. ### Claim 11 (depends on 10) A fermentation kit comprising a lid component according to claim 10. ### Claim 12 (depends on 1) A fermentation kit comprising a lid component according to claim 1. ### Claim 13 (depends on 12) The fermentation kit of claim 12, wherein the fermentation kit further comprises a glass jar and band of a mason jar. ### Claim 14 (depends on 1) The lid component of claim 1, wherein the peripheral side wall is substantially cylindrical in shape. ### Claim 15 (depends on 14) The lid component of claim 14, wherein the peripheral side wall is cylindrical in shape. ### Claim 16 (depends on 1) The lid component of claim 1, wherein the opening consists of perpendicular slits in the top wall. ### Claim 17 (depends on 1) The lid component of claim 1, wherein the sealing wall is planar. ### Claim 18 (depends on 1) The lid component of claim 1, wherein the sealing wall, side wall and top wall are of uniform thickness. ### Claim 19 (depends on 9) The fermentation kit of claim 9, wherein the fermentation kit further comprises a glass jar and band of a mason jar. ### Claim 20 A lid component for use with a glass jar and band of a mason jar, the lid component being made of an air-impermeable material and being dimensioned and configured to be releasably attachable to the jar by the band and to seal a wide mouth opening of the glass jar in an air-tight manner, the lid component comprising: a. a one-way valve adapted to allow gas produced by a fermentation process to escape from the jar while, at the same time, prevent oxygen-containing air from entering the jar, when the lid component is releasably attached to the jar; and b. a sealing wall, wherein the one-way valve comprises a bottom opening, a top wall, and a peripheral side wall extending from the bottom opening to the top wall, the peripheral side wall defining a space and the top wall having at least one opening biased towards a closed position and movable to an open position when pressure inside the space exceeds atmospheric pressure by a threshold amount; wherein the sealing wall extends radially outwardly from the bottom opening; wherein the sealing wall is substantially flat; wherein the lid component has a diameter; and wherein the bottom opening has a bottom opening diameter; wherein the sealing wall has a sealing wall diameter that is equal to the diameter of the lid component minus the bottom opening diameter; and wherein the sealing wall diameter is at least three (3) times greater than the bottom opening diameter. ### Claim 21 (depends on 20) A fermentation kit comprising a lid component according to claim 20. ### Claim 22 (depends on 21) The fermentation kit of claim 21, wherein the fermentation kit further comprises a glass jar and band of a mason jar. ### Claim 23 (depends on 20) The lid component of claim 20, wherein the opening consists of perpendicular slits in the top wall. ### Claim 24 (depends on 20) The lid component of claim 20, wherein the sealing wall is planar. ### Claim 25 (depends on 20) The lid component of claim 20, wherein the peripheral side wall is substantially cylindrical in shape. ### Claim 26 (depends on 25) The lid component of claim 25, wherein the peripheral side wall is cylindrical in shape.
