The nasal washer (10) according to the present invention has a valve (32), a container member (12), and a cap member (24), and the container member (12) receives the irrigation liquid (14). The cap member (24) is carried. The cap member (24) includes a discharge opening (64) for irrigation liquid (14) fluidly connected to the interior (11) of the container member (12) via a discharge channel (60). It has a nasal attachment (62) that is intended to be attached to the user's nostril (70, 92). According to the present invention, the container member (12) or the cap member (24) is assigned a mouthpiece (44) for controlling the valve (32), and the valve (32) is in the inoperative position. Since it is closed, the irrigation liquid (14) is prevented from flowing out through the nasal fitting (62) and under the action of breathing air when the user blows into the mouthpiece (44). Since the valve (32) can be brought into the open position, the irrigation liquid (14) flows out through the nasal fitting (62) and breathing air or ambient air enters the container member (12). To allow the above outflow. [Selection] Figure 2本発明に係る鼻洗浄器(10)は、バルブ(32)、容器部材(12)、及び、キャップ部材(24)を有し、上記容器部材(12)は、灌注用液体(14)を受容する役割を果たすと共に上記キャップ部材(24)を担持する。上記キャップ部材(24)は、上記容器部材(12)の内部(11)に対して放出チャネル(60)を介して流体接続された灌注用液体(14)用の吐出開口(64)を備えた鼻用取付具(62)を有し、該鼻用取付具(62)は、ユーザの外鼻孔(70、92)に対して取付けられることが意図される。本発明に依れば、上記容器部材(12)または上記キャップ部材(24)には、上記バルブ(32)を制御するマウスピース(44)が割当てられ、上記バルブ(32)は非作動位置において閉じられることから、上記鼻用取付具(62)を通る灌注用液体(14)の流出は阻止され、且つ、ユーザが上記マウスピース(44)内へと吹き込んだときに呼吸気の作用下で上記バルブ(32)は開き位置へともたらされ得ることから、灌注用液体(14)は上記鼻用取付具(62)を通り流出し、呼吸気または周囲空気は上記容器部材(12)内へと流入することで上記流出を許容する。【選択図】図2
