本実施形態に係る泡吐出容器1は、ノズル4の内部に供給された泡状の内容液を蓄圧して外部に噴射可能な蓄圧部10を有しているので、泡を垂れ落とさずに噴射することができる。すなわち、スクイズ操作を最初にする際には、ゆっくりとスクイズした場合でも、泡を蓄圧部10によって所定の圧力まで蓄圧した後に噴射できるので、泡を吐出口14から垂れ落とさずに噴射できる。また、スクイズ操作を連続して行う際にも、前回の操作による吐出後にノズルの内部に残った泡を、蓄圧部10によって所定の圧力まで蓄圧した後に噴射できる。したがって、本実施形態に係る泡吐出容器1は、スクイズ操作を連続して行う際にも、泡を吐出口14から垂れ落とさずに噴射できる。 Since the foam discharge container 1 according to the present embodiment has a pressure accumulator portion 10 capable of accumulating the foam-like content liquid supplied to the inside of the nozzle 4 and injecting it to the outside, the foam is ejected without dripping. can do. That is, when the squeeze operation is first performed, even if the squeeze operation is performed slowly, the bubbles can be ejected after being accumulated to a predetermined pressure by the accumulator unit 10, so that the bubbles can be ejected without dripping from the discharge port 14. Further, even when the squeeze operation is continuously performed, the bubbles remaining inside the nozzle after the ejection by the previous operation can be ejected after accumulating the pressure to a predetermined pressure by the accumulator unit 10. Therefore, the foam discharge container 1 according to the present embodiment can inject bubbles without dripping from the discharge port 14 even when the squeeze operation is continuously performed.

本実施形態に係る泡吐出容器1は、蓄圧部10がスリット弁11で構成されているので、簡単な構成にも関わらず、泡を垂れ落とさずに噴射することができる。本実施形態に係る泡吐出容器1は、スリット弁11が、ノズル4の基端側に向けて凸状に湾曲する凸状湾曲壁11bを有し、凸状湾曲壁11bにスリット11aが形成されているので、スクイズ操作時にはノズル4の内部で泡を効果的に蓄圧できる一方で、スクイズ操作後の容器本体2の復元変形時にはスリット11aをスムーズに開いて空気を外部から導入することができる。本実施形態に係る泡吐出容器1は、蓋体15で吐出口14を閉塞できるので、スリット11aへの内容液の固着を抑制し、安定した泡の噴射を実現できる。 In the foam discharge container 1 according to the present embodiment, since the accumulator portion 10 is composed of the slit valve 11, the foam can be ejected without dripping despite the simple configuration. In the foam discharge container 1 according to the present embodiment, the slit valve 11 has a convex curved wall 11b in which the slit valve 11 curves convexly toward the proximal end side of the nozzle 4, and the slit 11a is formed in the convex curved wall 11b. Therefore, while the bubbles can be effectively accumulated inside the nozzle 4 during the squeeze operation, the slit 11a can be smoothly opened and air can be introduced from the outside when the container body 2 is restored and deformed after the squeeze operation. Since the foam discharge container 1 according to the present embodiment can close the discharge port 14 with the lid body 15, it is possible to suppress the sticking of the content liquid to the slit 11a and realize stable foam injection.
