A venting assembly for a closed container having a lid and a container portion with a neck and a rim. The assembly comprises a venting unit having a substantially rigid ring having a lid-interfacing surface and a resilient annular valve member having a one-way valve disposed at the inner wall of the neck. The assembly further comprises at least one air passageway leading from the ambient atmosphere to the one-way valve member and a fixing mechanism adapted to prevent planar movement between the venting unit and the container.本發明主要係揭露一種具有排氣系統的密封容器,設一容器主體,容器主體之開口處設為瓶頸,該瓶頸上設有一外緣,又設有一排氣主體於瓶頸內,該排氣主體具有排氣效果,而排氣主體係由上扣件與下扣件所組成,上扣件係可使用較硬質材質所製成,而下扣件係可由彈性材質所製成,該在上扣件與下扣件之間的接口處並可向外形成若干個上透氣槽與下透氣槽,以成一向外產生排氣之通路,又設有定位裝置可對排氣主體做限制定位之功效,藉之,當容器主體內壓力提升,排氣主體可被打開並產生排氣洩壓功效來減緩負壓。100...容器主體102...奶嘴104...套蓋106...瓶頸108...外螺紋110...內螺紋112...外緣10...排氣主體12...上扣件14...下扣件
