また、本実施形態における空気弁４５は、弁筒体１７における本体筒３５の外周面に破断自在な弱化部４８を介して連結された空気弁４５と本体筒３５との一体成形体から弱化部４８が破断されて本体筒３５から分離されており、本体筒３５の外周面には、破断後の弱化部４８が残存している。図５を参照し、本体筒３５と空気弁４５とが連結した一体成形体が示されている。

Further, the main body cylinder 35 and the air valve 45 may be configured as separate members and assembled separately to the support plate portion 91.

また、本実施形態では、吐出口１３と連通孔９ｆとの間である連絡路Ｘに、弾性変位自在に支持されるとともに、吐出弁３６を、容器本体の内側である下方に向けて押圧する押圧体６０が配設されている。詳しくは、吐出筒部５１の下端部の内周面に押圧体６０が配設されている。 Moreover, in this embodiment, while being supported by the communication path X between the discharge port 13 and the communication hole 9f so as to be elastically displaceable, the discharge valve 36 is pressed toward the lower side inside the container body.

Further, on the upper surface of the plate body 40 of the discharge valve 36, a spherical concave portion 63 that protrudes downward is formed so that the front end portion of the pressing body 61 is supported.

次に、図４を用いて、以上説明した本実施形態による吐出容器１の典型的な使用方法について説明する。 Next, a typical method of using the discharge container 1 according to the present embodiment described above will be described with reference to FIG.

容器本体４の内容器２に収容された内容物を吐出させるとき、本実施形態の吐出容器１では、まずオーバーキャップ６を開け、例えば、吐出口１３が下方に向くような吐出姿勢とした状態で容器本体４の外容器３をスクイズ変形（弾性変形）させる。
これにより、内容器２が外容器３とともに変形して減容される。そして、この減容変形に伴い内容器２の内圧が上昇し、この内圧の上昇に伴い、吐出弁３６の連結部４１が弾性変形して板体４０が閉塞板部９の支持板部９１の膨出部９１ｘから吐出口１３側へ向けて離間し、連通孔９ｆが開放され、連絡路Ｘと連通する。これにより、内容器２の内部と吐出口１３とが連通し、内容器２に収容された内容物が連絡路Ｘを通って吐出口１３から吐出される。ここで、押圧体６０は、板体４０の変位に伴って吐出口１３側へ弾性変位される。なお、連絡路Ｘに流入した内容物等は、板体４０の径方向の外側を通って吐出口１３側へ流れる。 When discharging the contents stored in the inner container 2 of the container body 4, in the discharge container 1 of the present embodiment, the overcap 6 is first opened and, for example, the discharge posture is such that the discharge port 13 faces downward. Thus, the outer container 3 of the container body 4 is squeezed (elastically deformed).
Thereby, the inner container 2 is deformed together with the outer container 3 to reduce the volume. Then, the internal pressure of the inner container 2 rises along with this volume reduction deformation, and with this rise in internal pressure, the connecting portion 41 of the discharge valve 36 is elastically deformed, and the plate body 40 of the support plate portion 91 of the closing plate portion 9 Separating from the bulging portion 91x toward the discharge port 13 side, the communication hole 9f is opened and communicates with the communication path X. Thereby, the inside of the inner container 2 and the discharge port 13 communicate with each other, and the contents stored in the inner container 2 are discharged from the discharge port 13 through the communication path X. Here, the pressing body 60 is elastically displaced toward the discharge port 13 as the plate body 40 is displaced. The contents and the like that have flowed into the communication path X flow toward the discharge port 13 through the outer side of the plate body 40 in the radial direction.

また、このとき、外容器３がスクイズ変形（弾性変形）されることで、内容器２と外容器３との間は正圧になり、内容器２と外容器３との間にある空気が、吸気孔７ｃから吸気通路Ｙを通って外気導入孔５ｄから外部に流れようとする。ここで、吸気通路Ｙの途中にある弁座筒部９１ｂに着座した空気弁４５は圧力を受けて外気導入孔５ｄ側へ移動し、外気導入孔５ｄを閉じる。これにより、外気導入孔５ｄからの排出を規制された空気は、補助孔９５を通って連絡路Ｘへ流れる。これにより、この吐出容器１では、連絡路Ｘで気液混合がなされ、吐出筒部５１内に設けられた発泡部材１００により気液混合体が好適に発泡される。 At this time, the outer container 3 is squeezed (elastically deformed) so that a positive pressure is applied between the inner container 2 and the outer container 3, and the air between the inner container 2 and the outer container 3 is Then, the air tends to flow from the outside air introduction hole 5d through the intake passage Y through the intake hole 7c. Here, the air valve 45 seated on the valve seat tube portion 91b in the middle of the intake passage Y receives pressure and moves to the outside air introduction hole 5d side, and closes the outside air introduction hole 5d. As a result, the air whose discharge from the outside air introduction hole 5 d is restricted flows through the auxiliary hole 95 to the communication path X. Thus, in this discharge container 1, gas-liquid mixing is performed in the communication path X, and the gas-liquid mixture is suitably foamed by the foaming member 100 provided in the discharge cylinder portion 51.

その後、内容器２の内圧が低下すると、連結部４１が弾性復元力により復元変形して板体４０により連通孔９ｆが閉じられるとともに、連絡路Ｘと内容器２の内部との連通が遮断されて内容器２が密封される。このとき、押圧体６０は、弾性復元力により復元変形して板体４０を押圧した状態に復帰し、板体４０の閉じ状態を保持する。
また、さらに上述したスクイズ変形が解除されると、外容器３は復元変形しようとする。このとき、外容器３と内容器２との間に発生した負圧が吸気孔７ｃを通して空気弁４５に作用することにより、この空気弁４５が吸気孔７ｃ側へ向けて開いて吸気孔７ｃと外部とが連通され、外気が吸気通路Ｙを通して吸気孔７ｃから外容器３と内容器２との間に吸入される。そして、内容器２の減容形状が保持される。 Thereafter, when the internal pressure of the inner container 2 decreases, the connecting portion 41 is restored and deformed by the elastic restoring force, the communication hole 9f is closed by the plate body 40, and the communication between the communication path X and the inside of the inner container 2 is blocked. The inner container 2 is sealed. At this time, the pressing body 60 is restored and deformed by the elastic restoring force to return to the state where the plate body 40 is pressed, and the closed state of the plate body 40 is maintained.
Further, when the above-described squeeze deformation is released, the outer container 3 tries to restore and deform. At this time, the negative pressure generated between the outer container 3 and the inner container 2 acts on the air valve 45 through the intake hole 7c, so that the air valve 45 opens toward the intake hole 7c and the intake hole 7c The outside communicates with the outside, and the outside air is sucked between the outer container 3 and the inner container 2 through the intake passage Y through the intake hole 7c. And the volume reduction shape of the inner container 2 is hold | maintained.

この状態から、再び容器本体４の外容器３をスクイズ変形させると、空気弁４５は外気導入孔５ｄ側へ移動して外気導入孔５ｄを閉じる。そして、外容器３と内容器２との間の内圧が上昇し、この内圧の上昇によって内容器２が減容変形される。内容器２が減容変形されることにより、上述同様に内容物が吐出される。このように、スクイズ変形された外容器３が復元変形しても、内容器２は内容物の減少とともに減容されていき、しかも内容器２の内部に外気（内容物と一緒に封入された外気は除く）が流入することが防止されている。これにより、内容物の劣化が防止されて、保存性が高められている。
なお、吐出後は、オーバーキャップ６を吐出キャップ２４に装着する。 When the outer container 3 of the container body 4 is squeezed again from this state, the air valve 45 moves to the outside air introduction hole 5d side and closes the outside air introduction hole 5d. Then, the internal pressure between the outer container 3 and the inner container 2 rises, and the inner container 2 is deformed and deformed by the increase in the internal pressure. By reducing the volume of the inner container 2, the contents are discharged in the same manner as described above. As described above, even if the squeezed deformed outer container 3 is restored and deformed, the inner container 2 is reduced in volume as the contents decrease, and the outside air (enclosed together with the contents) is contained inside the inner container 2. (Except outside air) is prevented from flowing in. Thereby, deterioration of the content is prevented and the preservability is improved.
Note that the overcap 6 is attached to the ejection cap 24 after ejection.

以上に記載したように、本実施形態の吐出容器１によれば、吐出キャップ２４内に、吸気孔７ｃと外気導入孔５ｄとを連通する吸気通路Ｙが形成されるとともに、吸気通路Ｙ内に位置して空気弁４５を外気導入孔５ｄに対向させて離反自在に着座させる弁座部である弁座筒部９１ｂが備えられ、空気弁４５は、弁座筒部９１ｂと外気導入孔５ｄとの間を移動自在に配設されている。これにより、吸気通路Ｙにおける圧力変動に応じて空気弁４５が開閉し、弾性変形によらず空気弁４５を開閉させることが可能となるため、空気弁４５の開閉動作を安定させることができる。また、開閉動作に起因して空気弁４５に変形による癖がつき難く、長い期間、良好な開閉動作を維持でき、耐久性を向上できる。
また、この吐出容器１では、空気弁４５が、弁座筒部９１ｂの先端縁上に配設された環板部４６と、環板部４６から下方に向けて突出し、かつ弁座筒部９１ｂより径方向の外側に配置された突出部４７と、を備えていることで、空気弁４５の受圧面積を確保できるため、空気弁４５をスムーズに移動させることができる。 As described above, according to the discharge container 1 of the present embodiment, the intake passage Y that communicates the intake hole 7c and the outside air introduction hole 5d is formed in the discharge cap 24, and the intake passage Y has the inside. There is provided a valve seat cylinder portion 91b that is a valve seat portion that is positioned and is releasably seated facing the outside air introduction hole 5d. The air valve 45 includes the valve seat cylinder portion 91b and the outside air introduction hole 5d. Between them. As a result, the air valve 45 opens and closes according to pressure fluctuations in the intake passage Y, and the air valve 45 can be opened and closed regardless of elastic deformation. Therefore, the opening and closing operation of the air valve 45 can be stabilized. Further, it is difficult for the air valve 45 to be wrinkled due to deformation due to the opening / closing operation, and a good opening / closing operation can be maintained for a long period of time, thereby improving durability.
Further, in the discharge container 1, the air valve 45 projects from the annular plate portion 46 disposed on the leading edge of the valve seat tube portion 91b downward, and protrudes downward from the annular plate portion 46, and the valve seat tube portion 91b. Since the pressure receiving area of the air valve 45 can be ensured by including the protrusions 47 arranged on the outer side in the radial direction, the air valve 45 can be moved smoothly.

また、この吐出容器１では、空気弁４５が、本体筒３５の外周面に破断自在な弱化部４８を介して連結された当該空気弁４５と当該本体筒３５との一体成形体から弱化部４８が破断されて本体筒３５から分離されているので、空気弁４５を組付け途中で本体筒３５から分離させて空気弁４５を形成できるため、空気弁４５を容易に形成できる。

Since the air valve 45 is broken and separated from the main body cylinder 35, the air valve 45 can be formed by separating the air valve 45 from the main body cylinder 35 in the middle of the assembly, so that the air valve 45 can be easily formed.
In addition, the discharge container 1 is a foam discharge container, and the discharge cap 24 is formed with an auxiliary hole 95 that communicates the intake hole 7c and the communication path X between the discharge port 13 and the communication hole 9f. At the same time, the discharge valve 36 functions as an auxiliary valve that switches between communication and disconnection between the auxiliary hole 95 and the communication path X. The communication path X is provided with a foam member 100 that allows the contents and outside air to pass through and foam. Yes. Thereby, the contents can be suitably foamed using the outside air between the inner container 2 and the outer container 3. Moreover, in this embodiment, since the valve of the communication hole 9f and the auxiliary hole 95 is common, the number of parts is suppressed small.
