1230634 ⑴ 玖、發明說明 【發明所屬之技術領域】 本發明係關於一種收裝有藥液等的液體並利用泵作 用使該液體排出的排出容器。 【先前技術】 本案發明者們係如日本特開2 002- 1 8 3 3 0號公報上所揭 示，對作爲使藥液等的液體排出的排出容器提出了各種構 成的方案。這些排出容器係具備有：收裝液體的容器、及 設置在容器內部的缸筒、及在缸筒內滑動並藉由第1彈簧 被朝後退方向推彈的第1活塞、及在第1活塞前進時邊按壓 第2彈簧邊向後退的第2活塞。而且，利用當第1活塞達到 預定衝程時，讓連結缸筒與噴嘴的液體通路開口，讓第2 活塞藉由第2彈簧的推彈力而前進，而從噴嘴排出缸筒內 的液體。 根據這些排出容器，容器內的液體係藉由第2彈簧的 推彈力而被排出，同時因爲排出時的噴嘴之上下移動衹是 少許而已，故可以常時維持穩定的排出狀態。 另一方面，這種排出容器內所收裝的液體係涉及到醫 療領域或者化妝品領域等各種領域。這些液體之中大多是 較便宜的液體，因此關於收裝這些液體的容器，當然希望 以更簡易的構造而容易製造。 本發明係以改良排出容器爲目的，更詳細而言，係提 供一種以簡單的構造並能確保穩定的排出狀態的排出容器 -4· 1230634 (2) 爲目的。 【發明內容】 爲達成上述目的’本發明的排出容器係具備有··收裝 液體的容器；及在上述容器內從上方向下方延設並在上方 具有大徑部且還具備有從上述大徑部向下方縮小直徑的傾 斜部、與從上述傾斜部向下方延設的小徑部、與使容器內 的液體流入上述小徑部的流入口的缸筒；及自由滑動地配 設在上述大徑部的第1活塞；及具備有按壓上述第1活塞到 下方的同時按壓上述第1活塞時而將液體排出到上述容器 外部的排出口的引動裝置·，及自由滑動地配設在上述小徑 部且藉由彈簧被推彈到上方的第2活塞；及在沒有按壓上 述引動裝置的狀態下與上述第1活塞和上述第2活塞相抵接 且在上述第1活塞和上述第2活塞之間保持預定的間隔的間 隔保持構件。 另外，上述第1活塞係具備有：與上述大徑部的內圓 周面整周抵接成液密性的密封部；及具有與上述密封部存 在有間隔而被配置在下方並與上述密封部同時地上下移動 且在沒有按壓上述引動裝置的狀態下與上述大徑部的內圓 周面整周抵接成液密性的可彎曲性的閥體；及從上述閥體 的下端部朝向上述傾斜部且延設在下方的突出部；及通過 內部連結上述密封部與上述閥體之間的空間與上述排出口 的液體通路。而且，上述第2活塞係具備有：貫穿於上下 的流入通路；及設置於上述流入通路上且使得從下方流來 -5- 1230634 (3) 的液體通過而擋住液體從上方流下的流入閥。 而且，在按壓上述引動裝置時，上述第1活塞的閥體 係藉由上述缸筒內的液體使上述第2活塞下降而壓縮上述 彈簧，上述突出部被按壓到下方抵接到上述傾斜部時’又 被上述傾斜部引導伴同向內方移動，而使得上述閥體的一 部份離開上述缸筒的內圓周面，上述第2活塞係藉由上述 彈簧的推彈力，使上述缸筒內的液體從上述閥體與上述缸 筒之間的間隙，並經由上述液體通路從上述排出口排出之 特徵的排出容器。 如此，根據本發明的排出容器，當使用者按壓上述引 動裝置，藉由上述閥體與上述第2活塞之間的液體而壓下 上述第2活塞，上述彈簧即被壓縮。而且，上述突出部被 上述傾斜部引導，上述閥體呈現開口，液體藉由上述彈簧 的推彈力並經由上述液體通路從上述排出口排出。因此， 從上述排出口排出液體時，上述引動裝置的移動很少，因 此可以準確地排出液體。另外，排出液體的壓力係上述彈 簧的推彈力，因此可以隨時得到穩定的排出狀態。 在本發明的排出容器中，上述閥體的下端緣在水平方 向上形成平面狀較佳。或者，上述閥體係設置有從下端緣 朝向內方及向上方凹陷的凹部，具有可彎曲性且塡充上述 凹部的塡充構件塡裝於上述凹部內，上述塡充構件的底面 與上述閥體的下端緣形成平面狀亦佳。如此，由於上述閥 體或上述塡充構件的底面形成爲平面狀，縱使在上述缸筒 內混入有氣泡的場合下，上述缸筒內的液體係藉由被第2 -6- 1230634 (4) 活塞壓出時，該氣泡即經由上述閥體被排出到外部。因此 ’在下一次按壓引動裝置的場合，係在缸筒內沒有氣泡的 狀態下而能使液體排出。 另外’在使用上述塡充構件的場合下，亦可以在上述 塡充構件的中央設置有嵌裝上述間隔保持構件的收納孔。 在如此設置上述收納孔的場合，上述閥體因爲上述突出部 而發生變形時，由於上述收納孔發生變形，上述閥體亦就 容易發生變形。因此，可以容易地確保上述閥體與上述缸 筒的內壁之間的間隙，並且可以使液體順利地排出。 【實施方式】 接著’參照第1圖至第5圖說明關於本發明的排出容器 的實施形態的一例。本實施形態的排出容器1，係如第1圖 所示，包括：收裝液體2的容器3、及安裝於容器3的上端 部的引動裝置4。在該引動裝置4上設置有讓容器3內的液 體2排出的噴嘴4a(排出口）。 在容器3的內部收納有缸筒5。該缸筒5如第1圖所示， 在容器3的內部從上端向下方延設，在其上部裝設有大徑 部5 a，在其下部設有小徑部5 b。另外，大徑部5 a與小徑 部5 b間的臨接部份係形成直徑向下逐漸縮窄直徑的傾斜 部5 c。此外，從小徑部5 b的下方朝向容器3的底面延設有 流入口 6。 在缸筒5內，係收納有··具有閥體8的第1活塞7、第2 活塞9、彈簧1 〇、及間隔保持構件1 1。第1活塞7係藉由引 1230634 (5) 動裝置4朝上下方向自由滑動。閥體8係與第1活塞7形成一 體，藉由引動裝置4而被上下移動。第2活塞9係藉由引動 裝置4讓第1活塞7被壓下時，利用缸筒5內的液體2被壓下 。彈簧1 0向上方推彈第2活塞9。間隔保持構件1 1係被配設 在閥體8與第2活塞9之間。 第1活塞7及閥體8都係由具有可彎曲性的合成樹脂所 形成，並在缸筒5的大徑部5 a內自由滑動。第1活塞7係如 第1圖所示，具備有：朝向下方形成爲傘狀並與大徑部5a 的內圓周面的整周上抵接成液體密封的密封部7 a、延設在 密封部7a的上方之軸部7b、及設置在軸部7b內的液體通 路7c。閥體8係如第1圖及第2圖所示，具備有：朝向下方 形成圓頂狀的閥部8 a、延設在閥部8 a的下方之一對突出 部8b、延設在閥部8a的上方之軸部8c、及設置在軸部8c 內的液體通路8d。 另一方面，第2活塞9係由具有可彎曲性的合成樹脂所 形成，並在缸筒5的小徑部5 b內自由滑動。另外第2活塞9 係具備有：朝向上方形成爲傘狀並與小徑部5b的內圓周 面整周抵接成液密性的密封部9a、向上下貫穿中心部且具 有下方的小徑部1 2a和上方的大徑部1 2b的流入通路1 2、 及配設在流入通路12的大徑部12b內的逆止球13(流入閥） 。該逆止球1 3係因其自重而堵塞流入通路1 2的小徑部1 2 a ，從上方對液體2施加壓力時，使液體2無法從小徑部1 2a 流動到下方去。另一方面，液體2從小徑部1 2a的下方被 吸引上來的場合時，逆止球1 3會從小徑部1 2 a處浮上來， -8 - 1230634 (6) 使得液體2塡充到閥體8與第2活塞9之間的缸筒5內。 間隔保持構件1 1係如第1圖所示，在引動裝置4沒有被 按壓的狀態時，係被夾在閥體8與第2活塞9之間的狀態。 另外，其底面部係形成有將第2活塞9的流入通路1 2與第2 活塞9的上方的缸筒5內部連通的連通槽11a。 引動裝置4係第1活塞7的軸部8c被嵌合在其內部所設 置的液體通路4b上。另外，噴嘴4a係被設置在液體通路 4b的前端部，將經由液體通路4b被排出的液體2呈現霧狀 的機構。 接著，說明關於藉由本實施形態的排出容器1而將液 體2排出時的各個部位的動作。首先，如第1圖所示，在引 動裝置4沒有被壓下去的狀態時，在缸筒5的內部呈現被塡 充液體2的狀態。從這一狀態使用者一旦將引動裝置4向下 方壓下時，如第3(a)圖所示，第1活塞7及閥體8被壓下到 下方。隨之，由於壓力施加到閥體8與第2活塞9之間的液 體2上，所以第2活塞9一邊壓縮彈簧10—邊被按壓至下方 。此時，液體2雖然從缸筒5的大徑部5a移動到小徑部5b ，但是液體2的體積是不會改變。因此，如第3 (a)圖所示 ，按壓第2活塞9的衝程大於按壓閥體8及第1活塞7的衝程 。由此，讓間隔保持構件1 1的前端部離開閥體8。 當從該狀態再向下方按壓引動裝置4時，閥體8的突出 部8b抵接到缸筒5的傾斜部5c。當從這裏再向下方按壓引 動裝置4時，突出部8b沿著傾斜部5c向內方彎曲。由此閥 部8 a亦向內方彎曲，如第4圖所示，所以缸筒5的內壁與 -9- 1230634 (7) 閥部8a之間產生間隙1 4。由於缸筒5內的液體2係經由第2 活塞9而被彈簧1 0所推彈，所以液體2從缸筒5的內壁與閥 部8 a之間所產生的間隙1 4被推壓到上方。如此被推出的 液體2係通過閥體8的軸部8c內所設置的液體通路8d，接 著通過第1活塞7的軸部7b內所設置的液體通路7c，然後 再通過引動裝置4內部的液體通路4b，而後藉由噴嘴4a被 呈霧狀地排出到外部。 一直到藉由彈簧10容器讓第2活塞9上升，與第2活塞9 共同上升的間隔保持構件1 1抵接到閥體8爲止，液體2都在 持續地被排出外部。在此之間，液體2係藉由彈簧1 0的推 彈力以穩定的壓力從噴嘴4 a被排出。 使用者一旦從該狀態釋放引動裝置4時，藉由彈簧1 0 讓第2活塞9上升。隨之，閥體8及第1活塞7經由間隔保持 構件1 1也被推壓上來。此時，第1活塞7的密封部7a及閥 體8的閥部8 a係在缸筒5的大徑部5 a的內圓周面整周抵接 成液密性的狀態下滑動，由於閥體8與第2活塞9之間的缸 筒5內的液體2係從小徑部5b向大徑部5a移動，所以缸筒5 內呈現負壓。由此，第2活塞9下方的缸筒5內的液體2的壓 力高於閥體8與第2活塞9之間的液體2的壓力。因此，液體 2推上逆止球13，下方的液體2從第2活塞9的流入通路12進 入。由此，液體2經由間隔保持構件1 1的連通槽1 1 a被塡 充到閥體8與第2活塞9之間的缸筒5內。 如此，根據本實施形態的排出容器1，因爲藉由1個彈 簧1 〇就可以將液體2塡充到缸筒5內以及將引動裝置4推上 -10- 1230634 (8) ，所以構造簡單。另外，在本實施形態的排出容器1中， 缸筒5的形狀係從上方朝向下方以大徑部5 a、傾斜部5 c、 及小徑部5b的方式，直徑逐漸縮小的形式而形成，因此 ，在利用模具（未圖示）而射出成形缸筒5的場合時，在將 模具的構造可製成簡易的同時，又可以使得其射出成形簡 單易行。 下面參照第5(a)圖及第5(b)圖說明關於本發明的另一 實施形態的排出容器1。在另一實施形態中，如第5 (a)圖 及第5(b)圖所示，在閥體8的內部（凹部）安裝略呈圓筒狀的 塡充構件1 5。該塡充構件1 5係與閥體8同樣地藉由可彎曲 性的合成樹脂形成，在其中央設置有嵌裝間隔保持構件1 1 的收納孔1 5 a。塡充構件1 5其背面側係形成平面狀，並且 與閥體8的閥部8 a的下端緣形成相同高度。另外，其他的 構造與上述實施形態相同，因此在圖中使用與上述實施形 態相同的符號並省略其詳細說明。 根據該另一實施形態的排出容器1 ’，如第5 (a)圖所示 ，縱使在閥體8與第2活塞9之間的容器內混入有氣泡a的 氣體的場合下，亦會依附在塡充構件1 5的底面。而且，在 使用者按下引動裝置4，閥體8的閥部8 a與缸筒5的大徑部 5 a之間產生間隙時，氣泡A與所排出的液體2 —起被排出 到外部。因此，使用者在下一次按壓引動裝置4時，由於 在閥體8與第2活塞9之間已不存在有氣泡A，所以可以排 出準確量的液體2。另外，由於塡充構件1 5係在中央設置 有收納孔1 5 a，所以在閥體8的閥部8 a因突出部8 b而發生 -11 - 1230634 (9) 變形時，亦不會妨礙閥部8 a的變形。 在上述另一實施形態中，雖然將具有收納孔1 5 a的塡 充構件15’安裝於閥體8上，但是並不僅限於此’如第5(c) 圖及第5 (d)圖所示，也可以將不具有收納孔】5 a的塡充構 件〗5安裝於閥體8上，此時，間隔保持構件1 1僅縮短到塡 充構件15’的厚度較佳。另外，如第5(e)圖所示，閥體8自 身的底面部形成爲平面狀亦可。如此因爲閥體8或者塡充 構件1 5的底面形成平面狀，縱使在閥體8與第2活塞9之間 混入有氣泡A的場合下，在排出液體2時，亦可以使氣泡 A與液體2—起排出到外部。 【圖式簡單說明】 第1圖係顯示本發明實施形態之一例的排出容器之說 明性剖面圖。 第2圖係顯示閥體的說明圖。 第3(a)〜(X)圖係顯示第1圖的排出容器的動作之說明性 剖面圖。 第4圖係顯示缸筒與閥體之關係的說明圖。 第5(a)〜（e)圖係顯示另一實施形態的排出容器的重要 部份之說明性剖面圖。 〔圖號說明〕 1、1 ’ _·排出容器 2 :液體 -12- 1230634 (10) 3 :容器 4 :引動裝置 4 a :噴嘴 4 b、7 c、8 d :液體通路 5 :缸筒 5 a、1 2 b :大徑部 5b、12a ：小徑部 5 c :傾斜部 6 :流入口 7 :第1活塞 7 b、8 c :軸部 7 a、9 a :密封部 8 ·閥體 8 a .閥部 8 b :突出部 9 :第2活塞 1 〇 :彈簧 Π :間隔保持構件 1 1 a :連通槽 1 2 :流入通路 1 3 :逆止球（流入閥） 1 4 :間隙 1 5、1 5 ’ ：塡充構件 1 5 a :收納孔 -131230634 ⑴ 发明, description of the invention [Technical field to which the invention belongs] The present invention relates to a discharge container that contains a liquid such as a medicinal liquid and discharges the liquid by using a pump. [Prior Art] As disclosed in Japanese Patent Laid-Open No. 2 002-183-330, the inventors of the present case have proposed various configurations for a discharge container for discharging a liquid such as a medicinal solution. These discharge containers include a container for receiving liquid, a cylinder tube provided inside the container, a first piston that slides in the cylinder tube and is pushed back in a backward direction by a first spring, and a first piston. The second piston moved backward while pressing the second spring. Then, when the first piston reaches a predetermined stroke, the liquid passage connecting the cylinder and the nozzle is opened, and the second piston is advanced by the urging force of the second spring to discharge the liquid in the cylinder from the nozzle. According to these discharge containers, the liquid system in the container is discharged by the urging force of the second spring, and at the same time, the nozzle is moved up and down only slightly during discharge, so that a stable discharge state can be maintained at all times. On the other hand, the liquid system contained in such a discharge container involves various fields such as the medical field or the cosmetic field. Most of these liquids are relatively inexpensive liquids. Therefore, it is of course desirable that the container for storing these liquids has a simpler structure and can be easily manufactured. The present invention aims at improving the discharge container. More specifically, the present invention provides a discharge container -4 · 1230634 (2) with a simple structure and a stable discharge state. [Summary of the Invention] In order to achieve the above-mentioned object, the 'discharge container of the present invention is provided with a container for containing liquids; A slanted portion having a reduced diameter downward, a small-diameter portion extending downward from the inclined portion, and a cylinder tube with an inflow port for allowing liquid in the container to flow into the small-diameter portion; A first piston of a large diameter portion; and an actuating device provided with a discharge port that discharges liquid to the outside of the container when the first piston is pressed downwards while pressing the first piston downward, and is provided on the slide freely A second piston having a small diameter portion pushed upward by a spring; and abutting on the first piston and the second piston without pressing the above-mentioned driving device, and between the first piston and the second piston An interval maintaining member that maintains a predetermined interval therebetween. In addition, the first piston system includes a sealing portion that comes into contact with the inner circumferential surface of the large-diameter portion so as to be liquid-tight throughout the entire circumference; and a sealing portion that is disposed below the sealing portion with a gap from the sealing portion. A valve body that moves up and down simultaneously and abuts against the inner circumferential surface of the large-diameter portion over the entire circumference in a state without pressing the actuating device; And a protruding portion extending downward, and a liquid passage that internally connects the space between the sealing portion and the valve body and the discharge port. In addition, the second piston system includes an inflow passage that passes through the upper and lower sides, and an inflow valve that is provided in the inflow passage and allows liquid flowing from below -5- 1230634 (3) to pass and block the liquid from flowing downward. In addition, when the actuating device is pressed, the valve system of the first piston lowers the second piston by the liquid in the cylinder to compress the spring, and the protruding portion is pressed downward to abut the inclined portion. Guided by the inclined portion and moving inward, a part of the valve body is separated from the inner circumferential surface of the cylinder, and the second piston makes the liquid in the cylinder by the elastic force of the spring. A discharge container having a feature of discharging from a gap between the valve body and the cylinder and discharging from the discharge port through the liquid passage. As described above, according to the discharge container of the present invention, when the user presses the actuator, the second piston is depressed by the liquid between the valve body and the second piston, and the spring is compressed. The protruding portion is guided by the inclined portion, the valve body is opened, and the liquid is discharged from the discharge port through the liquid passage by the urging force of the spring. Therefore, when liquid is discharged from the above-mentioned discharge port, the movement of the above-mentioned actuating device is small, so that the liquid can be accurately discharged. In addition, the pressure of the discharged liquid is the pushing force of the spring, so that a stable discharging state can be obtained at any time. In the discharge container of the present invention, it is preferable that the lower end edge of the valve body is formed in a flat shape in a horizontal direction. Alternatively, the valve system is provided with a recessed portion that is recessed inward and upward from the lower end edge, and a filling member having flexibility and filling the recessed portion is installed in the recessed portion, and the bottom surface of the filling member and the valve body It is also preferable that the lower end edge is flat. In this way, since the bottom surface of the valve body or the filling member is formed in a flat shape, even if air bubbles are mixed in the cylinder tube, the liquid system in the cylinder tube is subjected to the 2nd to 6-1230634 (4) When the piston is pushed out, the bubbles are discharged to the outside through the valve body. Therefore, 'the next time the actuator is pressed, the liquid can be discharged without air bubbles in the cylinder. In addition, when the above-mentioned filling member is used, a storage hole may be provided in the center of the filling member to fit the space holding member. When the storage hole is provided in this way, when the valve body is deformed by the protruding portion, the valve body is easily deformed because the storage hole is deformed. Therefore, the clearance between the valve body and the inner wall of the cylinder can be easily ensured, and the liquid can be smoothly discharged. [Embodiment] Next, an example of an embodiment of the discharge container according to the present invention will be described with reference to Figs. 1 to 5. The discharge container 1 according to this embodiment, as shown in Fig. 1, includes a container 3 for receiving the liquid 2 and an actuating device 4 attached to an upper end portion of the container 3. The actuator 4 is provided with a nozzle 4a (discharge port) for discharging the liquid 2 in the container 3. A cylinder 5 is housed inside the container 3. As shown in Fig. 1, the cylinder 5 is extended inside the container 3 from the upper end to the lower side. A large-diameter portion 5a is provided on the upper portion thereof, and a small-diameter portion 5b is provided on the lower portion thereof. In addition, the adjacent portion between the large-diameter portion 5a and the small-diameter portion 5b is formed as an inclined portion 5c whose diameter is gradually narrowed downward. Further, an inflow port 6 is extended from below the small-diameter portion 5b toward the bottom surface of the container 3. In the cylinder 5, a first piston 7 having a valve body 8, a second piston 9, a spring 10, and a distance maintaining member 11 are housed. The first piston 7 is freely slid in the vertical direction by the 1230634 (5) actuator 4. The valve body 8 is formed integrally with the first piston 7 and is moved up and down by the actuator 4. The second piston 9 is pressed by the liquid 2 in the cylinder 5 when the first piston 7 is pressed by the actuator 4. The spring 10 pushes the second piston 9 upward. The interval maintaining member 11 is disposed between the valve body 8 and the second piston 9. Both the first piston 7 and the valve body 8 are formed of a flexible synthetic resin, and slide freely in the large-diameter portion 5a of the cylinder barrel 5. As shown in FIG. 1, the first piston 7 is provided with a sealing portion 7 a which is formed in an umbrella shape downward and abuts against the entire circumference of the inner circumferential surface of the large-diameter portion 5 a to form a liquid-tight seal, and is extended on the seal. A shaft portion 7b above the portion 7a and a liquid passage 7c provided in the shaft portion 7b. As shown in FIGS. 1 and 2, the valve body 8 includes a valve portion 8 a formed in a dome shape downward, a pair of protruding portions 8 b extended below the valve portion 8 a, and extended on the valve. A shaft portion 8c above the portion 8a and a liquid passage 8d provided in the shaft portion 8c. On the other hand, the second piston 9 is formed of a flexible synthetic resin, and slides freely in the small-diameter portion 5b of the cylinder barrel 5. In addition, the second piston 9 is provided with a sealing portion 9a which is formed in an umbrella shape upward and abuts against the inner circumferential surface of the small-diameter portion 5b so as to be liquid-tight over the entire circumference, and penetrates the center portion up and down and has a small-diameter portion below 1 2a and the inflow path 12 of the upper large-diameter portion 12b, and a check ball 13 (inflow valve) arranged in the large-diameter portion 12b of the inflow channel 12. The check ball 1 3 is a blockage of the small-diameter portion 12 a of the inflow path 12 due to its own weight. When pressure is applied to the liquid 2 from above, the liquid 2 cannot flow from the small-diameter portion 12 a to the bottom. On the other hand, when the liquid 2 is attracted from below the small-diameter portion 12a, the check ball 13 will float from the small-diameter portion 12a, -8-1230634 (6) so that the liquid 2 fills the valve Inside the cylinder 5 between the body 8 and the second piston 9. As shown in FIG. 1, the interval maintaining member 11 is a state where the space between the valve body 8 and the second piston 9 is held when the actuator 4 is not pressed. In addition, a communication groove 11 a is formed in the bottom surface portion to communicate the inflow path 12 of the second piston 9 with the inside of the cylinder 5 above the second piston 9. The actuating device 4 is a shaft portion 8c of the first piston 7 fitted into a liquid passage 4b provided inside the shaft portion 8c. The nozzle 4a is a mechanism provided at the front end portion of the liquid passage 4b, and the liquid 2 discharged through the liquid passage 4b has a mist-like mechanism. Next, the operation of each part when the liquid 2 is discharged by the discharge container 1 of this embodiment will be described. First, as shown in FIG. 1, when the actuator 4 is not depressed, the cylinder 5 is filled with the liquid 2. When the user depresses the actuator 4 downward from this state, as shown in Fig. 3 (a), the first piston 7 and the valve body 8 are depressed downward. Accordingly, since pressure is applied to the liquid 2 between the valve body 8 and the second piston 9, the second piston 9 is pressed downward while compressing the spring 10. At this time, although the liquid 2 moves from the large-diameter portion 5a to the small-diameter portion 5b of the cylinder 5, the volume of the liquid 2 does not change. Therefore, as shown in FIG. 3 (a), the stroke of pressing the second piston 9 is larger than the stroke of pressing the valve body 8 and the first piston 7. Thereby, the front-end | tip part of the space | interval holding member 11 is separated from the valve body 8. When the actuator 4 is further pressed downward from this state, the protruding portion 8b of the valve body 8 abuts against the inclined portion 5c of the cylinder barrel 5. When the actuating device 4 is further pressed downward from here, the protruding portion 8b is bent inward along the inclined portion 5c. As a result, the valve portion 8a is also bent inward, as shown in FIG. 4, so a gap 14 is generated between the inner wall of the cylinder 5 and the valve portion 8a. Since the liquid 2 in the cylinder 5 is urged by the spring 10 through the second piston 9, the liquid 2 is pushed from the gap 14 between the inner wall of the cylinder 5 and the valve portion 8a to Up. The liquid 2 thus pushed out passes through the liquid passage 8d provided in the shaft portion 8c of the valve body 8, then passes through the liquid passage 7c provided in the shaft portion 7b of the first piston 7, and then passes through the liquid inside the actuating device 4. The passage 4b is then discharged to the outside in a mist form by the nozzle 4a. The liquid 2 is continuously discharged to the outside until the second piston 9 is raised by the container of the spring 10, and the interval holding member 11 that rises together with the second piston 9 abuts against the valve body 8. In the meantime, the liquid 2 is discharged from the nozzle 4a at a stable pressure by the urging force of the spring 10. When the user releases the guide device 4 from this state, the second piston 9 is raised by the spring 10. Accordingly, the valve body 8 and the first piston 7 are also pushed up through the interval holding member 11. At this time, the sealing portion 7a of the first piston 7 and the valve portion 8a of the valve body 8 slide in a state where the inner circumferential surface of the large-diameter portion 5a of the cylinder barrel 5 comes into contact with each other in a liquid-tight manner. Since the liquid 2 in the cylinder 5 between the body 8 and the second piston 9 moves from the small-diameter portion 5b to the large-diameter portion 5a, the cylinder 5 has a negative pressure. Therefore, the pressure of the liquid 2 in the cylinder 5 below the second piston 9 is higher than the pressure of the liquid 2 between the valve body 8 and the second piston 9. Therefore, the liquid 2 pushes up the check ball 13, and the liquid 2 below enters through the inflow path 12 of the second piston 9. As a result, the liquid 2 is filled into the cylinder tube 5 between the valve body 8 and the second piston 9 via the communication groove 1 1 a of the interval holding member 11. As described above, according to the discharge container 1 of this embodiment, since the liquid 2 can be filled into the cylinder 5 and the actuator 4 can be pushed up by a spring 10, the structure is simple. In addition, in the discharge container 1 of this embodiment, the shape of the cylinder 5 is formed in such a manner that the diameter of the large-diameter portion 5 a, the inclined portion 5 c, and the small-diameter portion 5 b gradually decreases from top to bottom. Therefore, when the molding cylinder 5 is injected using a mold (not shown), the structure of the mold can be made simple, and the injection molding can be made simple and easy. Next, a discharge container 1 according to another embodiment of the present invention will be described with reference to Figs. 5 (a) and 5 (b). In another embodiment, as shown in Figs. 5 (a) and 5 (b), a substantially cylindrical filling member 15 is attached to the inside (recessed portion) of the valve body 8. The filling member 15 is formed of a flexible synthetic resin in the same manner as the valve body 8, and a receiving hole 15a in which a spacer holding member 1 1 is fitted is provided in the center thereof. The filling member 15 has a planar shape on the back side and has the same height as the lower end edge of the valve portion 8a of the valve body 8. The other structures are the same as those of the above-mentioned embodiment. Therefore, the same symbols as those of the above-mentioned embodiment are used in the drawings, and detailed descriptions thereof are omitted. As shown in FIG. 5 (a), the discharge container 1 ′ according to this another embodiment is attached even when the gas containing the bubble a is mixed in the container between the valve body 8 and the second piston 9. On the bottom surface of the filling member 15. When the user presses the actuating device 4, when a gap is created between the valve portion 8a of the valve body 8 and the large-diameter portion 5a of the cylinder 5, the bubble A is discharged to the outside together with the discharged liquid 2. Therefore, the next time the user presses the actuating device 4, since there is no air bubble A between the valve body 8 and the second piston 9, the accurate amount of the liquid 2 can be discharged. In addition, since the filling member 15 is provided with a receiving hole 15a in the center, the valve portion 8a of the valve body 8 is caused by the protruding portion 8b. -11-1230634 (9) It will not hinder the deformation Deformation of the valve portion 8a. In the other embodiment described above, although the filling member 15 'having the receiving hole 15a is mounted on the valve body 8, it is not limited to this, as shown in Figs. 5 (c) and 5 (d). As shown, the filling member 5 without a storage hole] 5 a can also be mounted on the valve body 8. At this time, it is preferable that the interval maintaining member 11 is only shortened to the thickness of the filling member 15 ′. In addition, as shown in Fig. 5 (e), the bottom surface portion of the valve body 8 may be formed in a flat shape. In this way, because the bottom surface of the valve body 8 or the filling member 15 is formed into a flat shape, even when the bubble A is mixed between the valve body 8 and the second piston 9, the bubble A and the liquid can be made when the liquid 2 is discharged. 2—Exhaust to the outside.
