Abstract: Provided is a gas permeable member including a gas permeable sheet configured to allow a gas to permeate therethrough; and a holder configured to hold the gas permeable sheet, wherein the gas permeable member is mounted in a container body having a surface on which a through hole communicating with an internal space is open by being inserted through the opening, so as to allow the gas to permeate therethrough between the internal space and the outer space of the container body via the gas permeable sheet, and the gas permeable member further includes a pressing part that contacts with an inner wall of the through hole and that presses the inner wall toward the open side at the contact position when a force is applied in a pull-out direction from the open side.

Abstract: A gas permeable member includes: a gas permeable sheet configured to allow a gas to permeate therethrough; a holder including a gas flow hole that allows the gas to circulate therethrough and configured to hold the gas permeable sheet inside the gas flow hole; a cover mounted on the holder so as to cover an opening of the gas flow hole on a side on which the gas is discharged; and a gas discharge path formed between the cover and the holder and configured to discharge the gas discharged from the gas flow hole between the cover and the holder.

Abstract: Provided is a gas permeable member including a gas permeable sheet configured to allow a gas to permeate therethrough and a holder configured to hold the gas permeable sheet, wherein the holder includes an insertion part into which the discharge part of the container body can be inserted, and a discharge opening through which the gas discharged into the holder from the discharge part inserted in the insertion part can be discharged to the outside of the holder, and the gas permeable sheet is held so as to intersect a gas flow path formed between the discharge opening and the discharge part inserted in the insertion part.

Abstract: A cover for gas permeable container which is mounted on a container body having an internal space and an opening communicating with the internal space includes: a closing part configured to close the opening; and a gas permeable part configured to be permeable to a gas, thereby allowing the gas to flow between the internal space and an outer space of the container body, wherein the gas permeable part is constituted by a gas permeable member having a gas permeable sheet, and the gas permeable member is integrally formed with a material constituting the closing part.

Abstract: Provided is a ventilation member including: a permeable member that includes a permeable sheet material that selectively allows a certain gas to pass therethrough, and a first frame body that supports a peripheral edge portion of the permeable sheet material; and a protection member that includes a protection sheet material, and a second frame body that supports a peripheral edge portion of the protection sheet material, wherein the permeable member and the protection member are integrally configured by the first frame body and the second frame body coupled to each other, and wherein the protection sheet material is disposed on at least one side of the permeable sheet material.
