口被壓大並進行開口，使液體等在吐出後用以開放賦予容 器本體之外壓使該彈性體藉由自己之復原力做爲關閉切口 之構造的止回閥或栓構造。 前者，係外觀以砲彈型在內部將具有圓項型之空洞的 栓以彈性或可撓性素材加以形成，並在其前端至少具備1 個切口。 又，後者係在圓弧狀將凸陷之薄板狀的上壁板以彈性 素材加以形成，並在其中央部具備有切口。 經濟部智慧財產局員工消費合作社印製 可是，上述任何先前技術中在閥機構之要部因爲使被 進入切口之彈性部進行露出，所以在不注意會碰觸其彈性 部。 該彈性部係爲了用以防止由切口之洩漏所以必要相稱 的彈力，但在用以提高必要以上彈力則使吐出變難使做爲 容器之方便性下降。因此，不要賦予過度之彈力，爲了使 切口閉止在該彈性體之彈力以外因爲未利用任何機構，在 原來爲了繼續用以貼緊切口僅以彈力係形成力量不足。因 本紙張尺度適用中國國家標準（CNS )

即，藉由容器本體之復原力使容器本體內形成負壓，到噴 嘴開口部爲止使被壓出之內容物會有再度被拉回到容器內 的情形。但在上述前者，使彈性部在容器內壓被設計不要 過度膨脹，相反使彈性部用以防止進行收縮不要任何處理 。因此，如第1 4圖所示彈性體係使筒狀部弄破會產生作 用於打開切口方向。 另一方，上述後者之例中也可產生同樣作用。即，凹 陷成圓弧狀之上壁板係使容器內在形成負壓時係與上述前 者之技術形成完全正相反之狀況，會容易使切口打開。 兩者係在如此之情形中，與其說是內容物之洩漏不如 說是會形成具有吸入空氣之缺點。 如此，習知技術係將切口做爲簡單的閥做爲利用之技 術，只不過被提出專利申請在容器內壓高時係進行容許吐 出，內壓下降則停止吐出之技術，而無在容器內用以防止 吸進空氣之技術的思想。因此，做爲閥機構雖然具有極簡 單的構成但是食品或化粧品，化學藥品等，由於與空氣接 觸在裝入忌諱氧化內容物的容器係實際上無法使用。 另外，做爲必要計量之液體係以藥品，化粧品爲首， 塗料，洗劑等種種。 本紙張尺度適用中國國家標準（CNS ) A4規格（210 X 297公釐） (請先閲讀背面之注意事項再填寫本頁) -5- 577844 A7 B7_ 五、發明説明（3) 在藥品等中，由瓶以計量枉進行量出加以使用之情形 被認爲最多。又，做爲比藥器1次使用量更多的洗劑等之 液體容器，係使瓶之蓋成爲計量枉或使泵式之合成樹脂製 瓶正在普及。前者係將計量枉由容器本體卸下加以使用， 可自由用以計量必要量，但正確的計量係不適合。又，後 者係在合成樹脂製之瓶容器本體的上方開口部具備手壓式 之泵，在必要時將該泵以手壓下能用以排出內容物。若據 此則藉由1次之手壓使吐出之量大致固定。 可是，具備計量枉之容器，係合對於設在計量枉之刻 度將內容量由容器本體流出加以使用，所以在正確的計量 係不適合，同時使流出方法不良則會溢出，又，流出口係 經常進行開口，所以以計量枉用以分配計量之內容物時由 容器本體內會流出多餘的內容物。進而蓋未鎖緊萬一容器 翻倒時會有使內容物洩漏之問題。 又，在泵式之瓶係使泵之反射彈簧爲金屬製等’以單 ‘材料之構成即使在技術上可會g ，但由成本之問題等而言 並非實際。現在環保意識在社會上正在高漲中，廢物處理 問題係不能不重視。 因此本發明，係用以提供一種止回閥及具備止回閥之 容器，用以解決如上之先前技術問題，同時確實發揮功能 〇 進而用以提供一種液體容器，具備本發明之液體計量 功能之容器，係用以解決上述先前之問題，同時以單一材 料可進行構成，同時不僅以單純之構造，而且，藉由止回 • 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） n am ί —^1 —ϋ ζ-^ϋ in ϋ

577844 A7 B7 經濟部智慧財產局員工消費合作社印製 五、發明説明（8) 2圖係止回閥本體周邊之要部縱剖面圖。 止回閥2係由第3圖之（a ) ( b ) ( c )如分別所 示之筒狀體4，閥體5，外皮體6及第2圖所示之保護蓋 7被構成。如第2圖及第3圖所示筒狀體4係使容器本體 側端部8爲了使流體抵抗減少被形成爲圓錐狀。筒狀體4 係爲了也具備有閥體5之形狀保持功能，所以以不容易變 形程度之硬度材料爲佳。 如第3圖（b )所示閥體5係被形成爲中空之砲彈型 ，在其前端係被設有切口 9。閥體5係以橡膠等之彈性體 被形成，切口 9在常態係藉由閥體5自體之彈力（復原力 )進行密接，但將容器本體3以手進行按下等藉由被賦與 外壓使容器變形時係以容器內壓使切口 9之密接容易被解 開形成開口部。 如第3圖（c )所示進而被具備有外皮體6能用以覆 蓋該閥體5。外皮體6也係具有用以限制閥體5之膨脹變 形的功能。形狀係與閥體5大致相同，但在其前端，係被 設有吐出口 2常時進行開口。做爲材料係多少具備有彈性 爲佳。吐出口 2係形成能適合具備於第2圖所示之蓋1 1 的突起1 2，兩者係藉由進行密接使殘留於吐出口通路 2 0內之內容物（液體，半流動體等）用以防止被接觸於 空氣進行氧化。 在外皮體6係在外面具有凸緣1 3，如第2圖所示進 行嵌合於容器本體3之筒狀部1 4，進而以保護蓋7被固 定。保護蓋7係形成能進行螺合於設在容器本體3之筒狀 (請先閱讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） -11 - 577844 A7 B7 五、發明説明（9) 部1 4之外側的螺釘。 (請先閲讀背面之注意事項再填寫本頁) 假如不如此構成時，即如第1 4圖所示無筒狀體情形 ，則藉由容器本體3之彈（復原）力使容器內壓形成負壓 時則使閥體5進行變形於內側使切口 9打開，或在閥體及 外皮體之間產生間隙會使空氣流入到容器本體內。又如第 1 5圖所示無外皮體6時則使閥體之切口 9幾乎不開口僅 進行膨脹。因此，如本發明，必定使筒狀體4，閥體5及 外皮體6之3個功能以有機性相互進行作用爲佳。 經濟部智慧財產局員工消費合作社印製 如第3圖及第4圖所示在筒狀體4之前端15及閥體 5之內側面1 6，以及閥體前端1 7及外皮體內側面1 8 之間係分別被設有空間A、B。空間A係由容器本體內通 過筒狀體4之通路1 9而來之內容物積存處，使該容積愈 大則用以分散閥體5之內側面1 6之壓力形成愈壓下。該 空間B之深度（在圖係上下方向之高度）C愈大則閥體5 膨脹愈大，而切口 9也形成打開更大的開口部。而且此等 空間A、B係第5圖所示筒狀體4之通路的口徑D，吐出 口之口徑E同時根據內容物之粘度適當進行變更並進行吐 出量或吐出容易性（爲了吐出加於容器本體之外壓的大小 )的調整。 如以上構成之本發明的止回閥2，係進行第6圖所示 之作用。 即，將容器本體3以手進行壓下等藉由被賦予之外壓 使容器內壓進行上昇，內容物係如圖中長箭頭所示朝向吐 出口 2被壓出。被壓出之內容物係通過筒狀體4之通路 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公f) 一 -12- 577844 經濟部智慧財產局員工消費合作社印製 A7 B：/五、發明説明（d 1 9進行到空間A。於是使空間A之內壓上昇將閥體5前 端之內面1 6朝向外推壓，所以閥體前端1 7係用以縮小 接觸於外皮體6之內面1 8爲止空間B並進行膨脹。與此 同時使設於閥體5之前端的切口 9進行開口並使內容物流 出由外皮體6前端之吐出口 2進行吐出。 用以開放容器本體3之外壓則以閥體5之彈（復原） 力使切口 9關閉停止吐出，但閥機構特別閥體5係直接浸 於內容物之狀態下關閉，所以由閥體5不會引進空氣到容 器本體3側。 不使用時，如第7圖所示關閉蓋1 1則使設於其中心 之突起1 2進行擋接密接於吐出口 2前端用以遮斷與空氣 之接觸。藉由做爲如此之構造，在閥體之內側有空間A使 閥體5在容器本體3使容易變形之構成，儘量在閥體5因 爲使被間隔之空間A、B間的壓力取得平衡，一旦被拉進 於容器本體3使切口

1係堅硬，具有開口部之頂部係爲 了關閉開口部若可確保必要充分的彈力則較柔軟爲佳。 第1 8圖各圖係將筒狀體4之通路1 9進行延長到與 閥體5接觸之頂部近傍爲止，進而使分歧成叉形。該情形 ，係使筒狀體4之頂部1 5及閥體5之前端部內側1 6進 行密接形成堵塞該通路1 9之開口部形狀。因此做爲閥機 構，係以該部分及設於閥體5之切口 9形成有2階段構成 。總之如第1 8圖（b )以箭頭所示由容器本體3被壓出 通過筒狀體4之通路19而來之內容物係將閥體5壓上在 筒狀體前端1 5及閥體前端內側1 6之間製作空間A (積 存處），以其內壓將閥體5進而壓上使膨脹並將切口 9打 開使開口。而且由外皮體6之吐出口 2進行吐出。當然僅 以前者做爲閥也可發揮充分的功能，所以設於閥體係並非 切口 9做爲開口孔也可係理所當然。根據使用之液體粘度 若分開使用即可。 第1 9圖及第2

Description of the invention (彳) [Technical Field] (Please read the precautions on the back and fill in this page) The present invention relates to check valves and liquid containers with check valves. [Technical background] Known technologies include the creation of Japanese Patent (Act) Shikai Sho 60-89143 and Shikai Hei 2-83257, which describe that an elastic body provided at the mouth of a container is provided with a cutout and borrowed at the same time. The external pressure is applied to the container to generate the internal pressure of the container. The cutout is enlarged and opened by the liquid being extruded, so that the liquid or the like is used to open the external pressure of the container body after being ejected, and the elastic body is caused to pass through. The check valve or bolt structure of the self-resilience is used to close the cutout structure. In the former, the outer shell is formed of a cannonball type with a round-shaped hollow bolt inside with an elastic or flexible material, and has at least one cutout at the front end. The latter is formed in a circular arc-shaped thin plate-shaped upper wall plate with an elastic material, and is provided with a cutout in a central portion thereof. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. However, in any of the above-mentioned prior arts, the elastic part of the valve mechanism is exposed because it is exposed in the main part of the valve mechanism, so it will touch the elastic part without notice. This elastic portion is required to have a corresponding elastic force in order to prevent leakage from the incision, but when it is used to increase the elastic force more than necessary, it is difficult to spit out and the convenience as a container is reduced. Therefore, do not apply excessive elastic force. In order to close the cutout beyond the elasticity of the elastic body, no mechanism is used, and the original force is insufficient to continue to close the incision. As this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) " -4- 577844 A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (2) As shown in Figure 1 3 It is shown that applying any external force to the elastic body is easy to deform because it will loosen the tightness of the cut, leak the liquid in the container, or otherwise form suction air in the container. More specifically, today, most of the tube containers are made of laminated materials, which makes the container itself resilient because of its elastomer. That is, a negative pressure is formed in the container body by the restoring force of the container body, and the extruded contents may be pulled back into the container again until the nozzle opening part is opened. However, in the former, the elastic part is designed to prevent the inner pressure of the container from being excessively expanded. On the contrary, the elastic part is used to prevent contraction without any treatment. Therefore, breaking the cylindrical portion of the elastic system as shown in Fig. 14 may cause a direction for opening the cut. On the other hand, the same effect can be obtained in the latter example. That is, the recessed arc-shaped upper wall plate makes the container completely opposite to the former technique when a negative pressure is formed in the container, and it is easy to open the cut. In both cases, the leakage of the contents is not so much a disadvantage as the inhaled air. In this way, the conventional technique is a technique in which a slit is used as a simple valve, but a patent application has been filed to allow the ejection to be performed when the internal pressure of the container is high, and the technique of stopping the ejection when the internal pressure drops is not in the container. The idea of a technique to prevent air inhalation. Therefore, although the valve mechanism has a very simple structure, food, cosmetics, chemicals, etc. cannot be practically used in a container system containing taboo oxidation contents due to contact with air. In addition, the liquid systems required for measurement include medicines, cosmetics, paints, lotions, and so on. This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the notes on the back before filling out this page) -5- 844 844 A7 B7_ 5. Description of the invention (3) In medicines, etc., It is considered to be the case where the bottle is measured out and used in a metering mill. In addition, liquid containers such as lotions, which are used more than a drug dispenser at a time, are widely used to make the cap of the bottle a metering bottle or a pump-type synthetic resin bottle. The former is used to remove the measuring cylinder from the container body and can be used to measure the necessary amount freely, but the correct measuring system is not suitable. In the latter case, a hand-pump type pump is provided at the upper opening of the synthetic resin bottle container body, and when necessary, the pump can be used to discharge the contents by manually pressing the pump. If this is the case, the amount of spit is approximately fixed by one hand pressure. However, a container equipped with a metering device is used to discharge the content from the container body to the scale set on the metering device. Therefore, it is not suitable for a correct metering system, and at the same time, if the outflow method is poor, it will overflow. The opening is opened, so when the metered contents are used to dispense the metered contents, excess contents will flow out of the container body. Furthermore, the lid is not locked in case the container leaks when the container is tipped. In the pump-type bottle, the reflection spring of the pump is made of metal, etc. 'Even if the structure of the material is technically possible, it is not practical from the viewpoint of cost and the like. At present, environmental awareness is rising in the society, and the issue of waste disposal cannot be ignored. Therefore, the present invention is used to provide a check valve and a container provided with the check valve, which are used to solve the previous technical problems as described above, and at the same time, do function. 0, and further provide a liquid container with the liquid metering function of the present invention. The container is used to solve the above-mentioned previous problems, and can be constructed with a single material at the same time, not only with a simple structure, but also with non-return. • This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm). n am ί — ^ 1 —ϋ ζ- ^ ϋ in ϋ (Please read the notes on the back before filling out this page) Order Printed by the Consumers ’Cooperatives of the Intellectual Property Bureau of the Ministry of Economy-6-577844 Employees’ Cooperatives of the Intellectual Property Bureau of the Ministry of Economy Printed A7 ______ B7__ 5.

Description of the invention (8) Figure 2 is a longitudinal sectional view of the main part of the periphery of the check valve body. The check valve 2 is composed of a cylindrical body 4, a valve body 5, a sheath body 6, and a protective cover 7 shown in Fig. 2 as shown in (a), (b), (c) of Fig. 3, respectively. As shown in Figs. 2 and 3, the cylindrical body 4 is formed in a conical shape so that the container body-side end portion 8 has a reduced fluid resistance. The cylindrical body 4 is preferably a hard material that is not easily deformed because it also has the shape retaining function of the valve body 5. As shown in FIG. 3 (b), the valve body 5 is formed in a hollow shell type, and a cutout 9 is provided at the front end thereof. The valve body 5 is formed of an elastic body such as rubber, and the cutout 9 is normally brought into close contact by the elastic force (restoring force) of the valve body 5 itself, but the container body 3 is pressed by hand or the like. When the external pressure deforms the container, the internal pressure of the container makes the close contact of the cutout 9 easy to be released to form an opening. As shown in Fig. 3 (c), a sheath body 6 is further provided to cover the valve body 5. The outer skin 6 also has a function to restrict the expansion deformation of the valve body 5. The shape is substantially the same as that of the valve body 5, but at the front end thereof, a discharge port 2 is provided to open constantly. As a material, it is better to have some flexibility. The discharge port 2 is formed with protrusions 1 2 which can be suitably provided with the cover 1 1 shown in FIG. 2, and both are contents (liquid, semi-fluid, etc.) remaining in the discharge port passage 20 by being tightly attached. To prevent oxidation by contact with air. The outer skin 6 has a flange 13 on the outside, and is fitted to the cylindrical portion 14 of the container body 3 as shown in Fig. 2, and is further secured by a protective cover 7. The protective cover 7 is formed in a cylindrical shape that can be screwed onto the container body 3 (please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210X297 mm) -11 -577844 A7 B7 V. Description of the invention (9) Screws on the outside of part 1 4. (Please read the precautions on the back before filling in this page.) If it is not structured as described above, that is, if there is no cylindrical body as shown in Fig. 14, the internal pressure of the container is formed by the spring (recovery) force of the container body 3. When the pressure is negative, the valve body 5 is deformed to the inside and the cutout 9 is opened, or a gap is created between the valve body and the outer skin body, so that air flows into the container body. When there is no outer skin 6 as shown in Fig. 15, the slit 9 of the valve body is hardly opened and is expanded. Therefore, according to the present invention, it is preferable that the three functions of the cylindrical body 4, the valve body 5, and the sheath body 6 interact with each other organically. The Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the front end 15 of the cylindrical body 4 and the inner side 16 of the valve body 5 as shown in Figs. 3 and 4, and the front end 17 of the valve body and the inner side of the outer skin 1 8 Spaces A and B are provided respectively. The space A is a place where the contents of the container body pass through the passage 19 of the cylindrical body 4, and the larger the volume, the more the pressure on the inner side 16 of the valve body 5 is dispersed. The larger the depth (the height in the vertical direction of the space) C of the space B, the larger the valve body 5 expands, and the cutout 9 also forms a larger opening. In addition, these spaces A and B are the diameter D of the passage of the cylindrical body 4 shown in FIG. 5, and the diameter E of the discharge port is appropriately changed according to the viscosity of the content, and the amount or ease of discharge is added. Adjustment of the external pressure of the container body). The check valve 2 of the present invention configured as described above performs the function shown in Fig. 6. That is, when the container body 3 is pressed down by hand or the like, the internal pressure of the container is raised by applying an external pressure, and the contents are pushed out toward the discharge port 2 as shown by long arrows in the figure. The extruded content passes through the cylindrical body 4.

Description of the invention (d 1 9 goes to space A. So the internal pressure of space A is raised and the inner surface 16 of the front end of the valve body 5 is pushed outward, so the front end 17 of the valve body is used to reduce contact with the outer skin. The inner surface 1 of 6 is expanded to space B at the same time. At the same time, the cutout 9 provided at the front end of the valve body 5 is opened and the contents are discharged from the outlet 2 at the front end of the outer body 6. It is used to open the container body. When the external pressure is 3, the incision 9 is closed and stopped by the spring (recovery) force of the valve body 5. However, the valve body 5 is closed by directly immersing the contents, so the valve body 5 will not introduce air to The side of the container body 3. When not in use, close the lid 11 as shown in Fig. 7 so that the protrusion 1 2 provided at the center of the container is closely sealed to the front end of the discharge port 2 to block the contact with the air. For this structure, there is a space A inside the valve body so that the valve body 5 The container body 3 is easily deformed. As far as possible, the pressure between the space A and B in the valve body 5 is balanced. Once it is pulled into the container body 3 to make the cut 9 open, it returns to the normal cut. 9 is in a state of close contact. The cover 1 1 can be selected from the types shown in Fig. 7 except for the type with a hinge or a spiral type, but any type is in the center. It is necessary to provide protrusions 12 as a structure for blocking the discharge port 2. As described above, by adjusting the diameter D of the cylindrical body 4, the diameter E of the discharge port or the spaces A and B, the contents are discharged by the discharge port 2. The formation can be controlled freely from the drop to the continuity. Figures 8 (a) to (c) show the cuts provided at the front end of the valve body 5.

Fig. 9 (a) to (e) are plan views of the cutouts 9 of different shapes. However, the opening provided in the valve body 5 is not limited to The cutout 9 is opened by the increase of the internal pressure of the container, and the mechanism is not limited if the internal pressure of the container is opened when the internal pressure of the container is opened. As described later, the so-called opening hole may be unnecessary. Even FIG. 12 is an example of application to various container bodies 3 of the check valve 2 of the present invention. FIG. 10 is a plastic bottle that is deformable under external pressure, which is often used for the container body 3 of shampoo, etc., and FIG. 11 It is an application example for a square packing bag and FIG. 12 for a vertical packing bag container. 11 and 12 are so-called bag-shaped containers. In this way, the check valve of the present invention can be applied to all types of containers by pressing the container body 3 by hand to apply external pressure to generate internal pressure in the container body and spit out the contents. On the other hand, it is not applicable to make the container body not deformed by external pressure, such as a glass bottle. 16 to 20 show other embodiments of the check valve 2 of the present invention. Fig. 16 shows a case where two cutouts are provided, and Fig. 17 shows a case where the cylindrical body 4 and the valve body 5 are integrally formed. In this case, the whole is made of an elastic material such as rubber as a whole, or the cylindrical body 4 is formed of a hard material such as plastic, and the elastic body of the valve body 5 may be used to cover the cylindrical body 4. If the entire body is formed of a soft material, if the cylindrical body part 2 1 is provided with a sufficient wall thickness, deformation can be suppressed on the inside (please read the precautions on the back before filling this page) This paper size applies Chinese national standards (CNS) A4 specifications (210X297 mm) -14- 577844 A7 B7 V. Description of the invention (j 'but the preferred cylindrical body part 2 1 is hard, the top with the opening is to close the opening if necessary to ensure sufficient The elasticity of the elastic body is better. Figures 18 and 8 extend the passage 19 of the cylindrical body 4 near the top of the body contacting the valve body 5, thereby diverging into a fork shape. In this case, the barrel The top portion 15 of the shape body 4 and the inner side 16 of the front end portion of the valve body 5 are closely contacted to form the shape of the opening portion that blocks the passage 19. Therefore, as the valve mechanism, the portion and the cutout 9 provided in the valve body 5 are formed. It consists of two stages. In short, as shown in Figure 18 (b), the container body 3 is pushed out through the passage 19 of the cylindrical body 4 as shown by the arrow. The valve body 5 is pressed against the front end of the cylindrical body. Make a space A (storage place) between 1 5 and 1 6 inside the front end of the valve body. Its internal pressure pushes the valve body 5 further up and expands and opens the cutout 9 to open it. Moreover, it is discharged from the outlet 2 of the outer skin body 6. Of course, only the former can play a sufficient function as a valve, so it is provided in the valve The system does not need to be the cutout 9 as an opening. It can be taken for granted. Depending on the viscosity of the liquid used, it can be used separately. Figures 19 and 20 show the situation with a discharge adjustment mechanism. That is, the valve and the vomit are always made. The opening of the outlet changes the amount of discharge as the internal pressure of the container rises. However, when the internal pressure of the container body 3 is not paid attention, the contents are formed by the outlet 2 to jump out. Therefore, this mechanism can be prevented.

Push out so that the content coming through the passage 19 presses the protrusions 23 of the valve body 5 as shown in FIG. 20 (a) and releases the tight contact between the two. Then, the gap is opened so that it flows out through the opening 2 4 provided around the protrusion 2 3 of the valve body 5 and flows out through the outlet 2 of the outer body 6 for discharge. However, when the internal pressure of the container is further increased, as shown in FIG. 20 (b), the protrusions 2 and 3 of the valve body 5 are further pushed up so that the upper side, that is, the front end 17 of the valve body 5, is blocked by the outer skin body 6. The lower end 25 of the spout outlet 2 forms a clogged spout outlet 2. With this configuration, the contents are formed and discharged only when the fixed container is in the body.

Description of the invention (the pressure of 〇 is closed when the pressure is positive, and it is opened when the pressure is negative. (Please read the precautions on the back first) (Fill in this page) The suction port 38 is provided in the cover 7 in this embodiment, but it can also be provided in the container body. The liquid meter of the present invention configured as described above is used as follows. As shown in FIG. 31, the container body 3 is pressed with the fingers and the like to increase the internal pressure. The content (liquid) of the internal pressure rises into the suction tube 32 and faces the discharge port as shown in FIG. 31. As shown in the figure, the check valve 1 is opened to flow out into 枉 29. At this time, only the check valve 1 on the discharge side is opened, and the check valve 4 on the suction side is closed. The liquid level reaches 枉The scale is used to pressurize the container body 3. Figures 3 and 3 show the state of measuring the required amount when it is not inside the cymbal. When 枉 2 9 makes the required amount accumulate, the hand pressing the container body 3 is released. In order to exclude the pressure applied to the container body 3, the check valve 1 is automatically performed by the elasticity of the valve body 5. As shown in Figures 3 and 4, the container body 3 uses the elasticity of the container body 3 to restore the force to create a negative pressure in the container body. This time, the check valve 4 3 of the suction port 3 8 is opened to allow external air to flow in. Into the container body. If the internal pressure of the container and the pressure outside the container are balanced, the check valve of the suction port 3 8 is printed by the Intellectual Property Bureau Staff Consumer Cooperatives of the Ministry of Economic Affairs 4 3 and is automatically locked by its own elastic force. As a result, the contents in the pan can be dispensed. As a result, when the content that has been measured is discharged (dispensed) from the pan, the discharge port 2 will not flow out excessively, and it will not cause the container body to be tipped over. The contents are spit out.

Therefore, it is possible to provide a check valve suitable for dripping and discharging of contents (liquid, semi-fluid, etc.) and a container having a check valve and having high storage stability. Inside The dripping and discharging of the contents makes it extremely easy to control the pressure applied to the container, and in order to prevent the valve mechanism part from being exposed so that the valve mechanism will not be subjected to external pressure, etc., the function of returning the valve can be reliably prevented, and air can be prevented from flowing back into the container. In vivo. Therefore, it is very suitable for taboo contents (food, cosmetics, chemical devices, etc.) that can be used for taboo contact with the air. The amount of content to be discharged can also be adjusted freely according to the viscosity. A functional liquid container, if it has a flexible liquid container, it can be applied to a variety of containers, and it is easy to adjust the discharge amount of the contents, and it can be easily measured. Moreover, even if the container body is not pressurized, the contents will not be made. The discharge is performed so that it is not discharged from the container body more than the measured amount, so the measurement accuracy is high. Furthermore, the metering grate can be removed and washed, so it is hygienic.
