This creation is the volume control device of drinking container,It is a disk body,And an accommodating space has been axially penetrated through,Outer spoiler and interior spoiler equipped with axially spaced-apart setting in accommodating space,It is regarded from axial,Outer spoiler is jointly completely obscured by accommodating space with interior spoiler； It is installed between what bottle body and suction nozzle when use,When bottle body is tilted,Liquid flows out Hou from bottle body,Each interior spoiler in accommodating space can be first struck,Hou flow into accommodating space and strike each outer spoiler again,Then gap outflow of the conversion direction Hou between outer spoiler and interior spoiler,Suction nozzle just arrived at by most Hou； By making liquid experience multiple impact and steering,Effectively to slow down the flow and flow velocity of liquid,And then suction nozzle is avoided to be oozed out excessive liquid when being stung by suction by the impact of big quantity of fluid,It is choked to avoid baby.本創作係飲用容器的流量控制裝置，其為一盤體，且軸向貫穿有一容置空間，容置空間內設有軸向間隔設置的外阻流板及內阻流板，從軸向視之，外阻流板與內阻流板共同將容置空間完全遮蔽；使用時裝設於瓶體與吸嘴之間，將瓶體傾斜時，液體從瓶體流出後，會先撞擊到容置空間內的各內阻流板，之後流進容置空間而再次撞擊到各外阻流板，接著轉換方向後從外阻流板與內阻流板之間的間隙流出，最後才抵達吸嘴；藉由使液體經歷多次撞擊及轉向，以有效減緩液體的流量及流速，進而避免吸嘴受到大量液體的衝擊而在被吸咬時滲出過多液體，以避免寶寶嗆到。
