573241 A7 B7 五、發明説明（彳） 〔發明所屬之技術領域〕 本發明是有關從本體排出內容物（液體）時，以 手按壓容器本體等加壓可容易如點滴狀排出之點滴吐出流 速控制容器。 並且是關於一種具備吐出流速控制機構具備可計測一 定量之定量計量容器的定量計量流速控制容器。 〔先前技術〕 至今，以飮料水容器爲中心已普及使用寶特瓶，形狀 也同時多種多樣流通於市面。並且，關於以洗劑容器爲中 心的塑膠瓶，雖然提案較寶特瓶以上之多樣型式的容器， 但是從垃圾減量化及資源再利用的觀點來看已有參J尤容器 作爲補充用容器的普及。 但是以往的容器係集中注目於容器本體，關於排出口 的設計則有被棄置的感覺。亦即，皇遣座從容器噴出內.容 物J年事、.故.乂例如傾向大容量化之寶特瓶時重量大不能有效 排出控制而會從容器中溢出，或者將洗劑從補充用袋容器 塡充至塑膠瓶內時，不小心擠壓袋容器而自排出口噴出， 或因爲容器本體扭曲使排出口偏離目的方向而造成周圍污 染等問題。 因此必須在排出口的構造上下工夫以使收容於容器內 之液體不致因不注意而從容器內吐出，有鑑於此申請人於 日本專利特開平1 〇- 3 3 827 8號中，提案一種可控制排出口之 液體流速的技術。 (請先閱讀背面之注意事項再填寫本頁) 訂 經濟部智慧財產局員工消費合作社印製 本紙張尺度適用中國國家標準（CNS ) A4規格（21〇'〆297公釐） -4 - 573241 A7 B7 五、發明説明（2 ) 另一方面’尤其是如眼藥水等有從液體容器呈點滴狀 排出內容物必要的容器。有點滴狀排出之必要性的液體除 了眼藥水之外，化妝品及食品添加物等的多樣性。 以往的點滴吐出容器是形成以眼藥水爲代表的有單純 微小之容器排出口，藉液體的表面張力停止液體，並以手 指等按壓容器本體提高內壓擠出的構造。又，化妝品或食 品添加物的容器，其排出口僅單純形成與眼藥水相同的微 小口，此時與其以擠壓容器本體倒不如說是以搖動容器本 體爲多數。 但是，從點眼藥水的經驗而言，排出1滴所須按壓容器 本體之力的控制困難，不只1滴而擠出2滴時，必須進行力 . - ' ' 〜.一.…τ 的微調。因此在容器本體材料的選擇（容器的硬度、剛性 )自由度低。因此，例如從層積管柔軟容器本體點滴排出 內容物等極爲困難，必然性地僅能使用具備適當硬度及剛 性的塑膠或玻璃製容器。 有鑑於此本發明的點滴吐出流速控制容器是提供一種 可解決上述習知課題的同時，內容物的點滴排出極爲容易 之外，容器本體的限制少，提供可運用多樣軟性容器的點 滴吐出容易之排出口的液體容器。 且以往作爲洗劑等的液體容器普及於泵式的樹脂製瓶 。此係於樹脂製之瓶容器本體的上方開口部具備手按壓式 泵，必要時以手按壓該泵排出。 該泵即是所謂的柱塞泵，按壓手按壓部時將滯留泵內 的內容物從排出口排出，手一旦離開時即藉著復位彈簧將 本紙張尺度適用中國國家標準（CNS ) A4規格（210 X 297公釐） (請先閱讀背面之注意事項再填寫本頁) 、?τ 經濟部智慧財產局員工消費合作社印製 -5- 573241 A7 B7 五、發明説明（3 ) (請先閱讀背面之注意事項再填寫本頁) 手按壓部推回的同時，從容器本體內吸取內容物的構造。 栗內通常設置有止回球，此係形成止回閥，可防止一旦被 吸入泵內的內容物不會再度逆流至容器本體內。又，在泵 本體下端設置細管，形成可以將內容物從容器本體的底部 吸上。並且該容器多是利用於洗劑、洗髮精等黏性較高的 液體，形成極爲普遍的容器。 但是’泵之復位彈簧爲金屬製等，單一材料的構成雖 在技術上可行，但是成本的問題等上即非現實可得。此外 在環保意識高漲的社會中，垃圾的問題也已到了不可忽視 的程度。 又，由於在泵內設置逆流防止用的止回閥，因此內容 物從泵滯留至吐出口爲止間的管內而硬化，在接著的吐出 時會有硬化的內容物噴出等問題。 經濟部智慧財產局員工消費合作社印製 因此本發明之液體容器除了解決上述習知課題的同時 ，可以單一材料構成，不僅具有單純的構造，並可防止因 流速控制不注意時的吐出，同時可提供吐出管內的內容物 不致吸入容器本體內而導致內容物滯留管內硬化的液體容 器。 此外，以往必須要計量的液體最初是藥品、化妝品， 以至塗料、洗劑等種種的液體。藥品等中，最多是以瓶或 量杯計量使用的方式。又，較藥品1次使用量多的洗劑等的 液體容器則普遍以瓶蓋作爲量杯或泵式的合成樹脂製瓶。 前者是將量杯從容器本體取下後使用，可根據需要量自由 計量，不適合正確的計量。又’後者是在合成樹脂製之瓶 -6- 本紙張尺度適用中國國家標準（CNS ) A4規格（21〇><297公楚） 573241 經濟部智慧財產局員工消費合作社印製 A7 ___ B7五、發明説明（4 ) 容器本體的上方開口具備手按壓式栗，必要時以手按壓此 一泵排出內容物。根據此1次的按壓吐出的量大致係形成一 定。 但是，具備量杯的容器，由於是配合設置在量杯的刻 度將內容物從容器本體擠出使用，因此不適合正確計量， 同時擠出方法不當時有溢出，或者蓋的栓緊不足而萬一使 容器傾倒時，會有內容物洩漏等的問題。 又，泵式的瓶中泵的復位彈簧爲金屬製等時，單一材 料的構成雖在技術上可行，但是現實上會有成本上的問題 〇 另外，在泵內設置逆流防止用的止回閥，因此從泵至 吐出口之間的管內，內容物會滯留其中而硬化，會有在接 著吐出時會使硬化的內容物噴出等問題。 有鑑於此本發明之液體容器除了解決上述習知課題的 同時，可以單一材料構成，不僅具有單純的構造，並可防 止因流速控制不注意時的吐出，同時可提供吐出管內的內 容物不致吸入容器本體內而導致內容物滯留管內硬化的液 體容器，同時可提供一定量之正確計量的液體容器。 〔發明內容〕 亦即具備本發明之吐出流速控制機構的容器具有以下 的特徵。 (1)具備排出內容物之排出路徑的液體容器中，該排出路徑 上，具備有常壓下利用內容物的表面張力封閉內容物本身

利用細管的管內阻力使容器本體內壓衰減不致直接影響流 速控制通路的特徵。 實施發明之最佳形態。 針對本發明之實施例詳述如下。 〔實施方式〕 (實施例1 ) 第1圖是表示具備點滴吐出液體排出口之點滴吐出流速 控制容器的透視圖。容器本體1上係以具備排出口 2之排出 管3及將此排出管3固定按壓於容器本體1的壓蓋4所構成。 並在壓蓋4上端準備防止不使用時因不注意而排出用及保護 排出口

開□部7如第3圖所示外形係形成具備突緣8的形狀，中央爲 具備主要排出通路（以下，稱主通路）9的管狀構件。該主 通路9係如圖所示，下部呈非貫穿狀，下端是藉著底部1〇封 閉。並在其底部10附近其側壁丨丨與上述主通路9直行的方向 上設置作爲流速控制通路的微小剖面孔（以下，稱微窄通 "—'^ 一· "" — 一—*——.—-〜 …...一…. 路）12。該微窄通路12爲1 彳莖收納之液體的表面張力或j

整流）該通路出口之內容物的流出狀態用的長形爲佳。即 過短時會在通路出口擴散，使相對之內容物彼此間不能有 效地衝突。其理由係如下述。 微窄通路1 2如第4圖所示，係設置於相對位置上。此係 如第5圖所示從微窄通路12吐出至主通路9內的內容物（液 體）係於主通路9的大致中央衝突，藉此可使吐出流速形成 -11 - 本紙張尺度適用中國國家標準（CNS ) A4規格（210 X 297公釐） 573241 A7 B7 經濟部智慧財產局員工消費合作社印製 五、發明説明（9 ) 0 (零）。因此不會以通過微窄通路1 2狀態的流速從排出口 2吐出內容物。 此外，微窄通路12其直徑越小，雖然可限制通過該微 窄通路12之內容物的量，但是在主通路9內需要充滿內容物 的時間，同時相對於作用於容器本體1的外壓（手指按壓力 )變的鈍感。亦即從排出口 2滴下之內容液滴下述的調節與 其是按壓容器本體1之力的大小倒不如說是依據按壓時間的 長短，滴下的控制變的極爲容易。並且滴下的速度是藉外 壓（按壓容器本體1的力）的大小是根據其微窄通路的通過 流速，但是滴下的控制可藉著按壓容器本體1的時間或力的 重視以改變微窄通路12的有效開口面積（孔徑）來變更。 並且，其微窄通路12的開口面積的大小可根據容器本體1的 柔軟性的程度適當變更而獲平衡，藉此可配合收納容器內 之內容物的性狀及滴下條件而精密地加以對應。 以上構成之第1實施例之點滴吐出流速控制容器的使用 時，如第6圖所示，將容器傾倒以手指按壓容器本體1的壓 力作用時，使容器本體1如圖中虛線變形使容器內壓上昇， 內容物（液體）如第7圖所示從容器本體1流入微窄通路12 ，如第5圖所示從微窄通路12朝著主通路9的中央擠出的同 時，以同速度吐出互相衝突使速度一旦形成0。而不致從排 出口

通過微窄通路1 2狀態下的流速從排出口 2吐出，因此內容物 的流出極爲緩慢，即使因不注意的外壓作用於容器本體i時 ’也不致從排出口 2噴出，可極爲容易地進行滴下量的微調 。即可容易計量1滴落下的時間，或者也可以容易計算滴下 數量，並可容易吐出。 排出後排除外加容器本體1的外壓時，藉著容器本體 的復原力’將押入量的空氣吸入容器本體1的同時，排出路 徑內的內容物同時被吸入容器本體丨內，在主通路9內內容 物不會殘留其中獲得極爲良好之排出口 2的排液性而不會有 剩餘滴下。 此外，主通路9內由於不會有內容物的殘留，因此即使 因不注意外壓作用於容器本體1時主通路9內未成充滿狀態 時不會從排出口 2流出。又微窄通路12是如上述藉著表面張 力或毛細管現象加以封閉，或形成混合氣泡時的所謂汽鎖 狀態’具有在常壓下不容易通過程度的直徑之通路，但是 藉著容器復原時的吸力在微窄通路1內不會有殘留物。 排出口 2的直徑只要在常壓力藉著毛細管現象使內容物 不會殘留滴下程度的直徑即可，例如水的低黏度液體時 1.5mm至3mm左右爲佳.，但是可根據內容物的性狀或容器的 使用目的適當變更。或者不需要相同之排出口 2的內徑與主 通路9的內徑，當然也可以形成細長主通路1的場合或相反 地形成大的主通路。 另外，也可以1個微窄通路1 2但是此時與壁面衝突等則 必須要有使微窄通路1 2噴出時的速度形成零的手段，因此

路12在3個以上時，在大致中央配置使所有微窄通路12噴出 的內容物衝突之輻射狀即可。（c)更表示4個微窄通路的場合 。微窄通路爲偶數個的場合也可以複數條平行配設同圖（c) 表示的微窄通路對。 另外，微窄通路12其他可同時考慮第9圖表示的型態。 即，從微窄通路12之流入方向的速度爲零時，從微窄通路 12流入的內容物與壁或相對流入之內容物衝突時之外，並 包含強的流動方向轉變的場合。例如第9圖中，（a)是從側壁 11之微窄通路12流入的內容物與對面的內壁衝突，（b)是在 主通路9的底部中央豎立設置衝突壁13,從夾持該衝突壁13 方向之側壁11的微窄通路12流入內容物與該壁衝突，（c)是 從設置在側壁11之非對向位置的微窄通路12流入的內容物 以對面內壁呈非直角的角度衝突，此時由於內容物是沿著 主通路9的內壁轉變方向流動，因此在主通路9內會產生渦

以上構成之第2實施例的點滴吐出流速控制容器在使用 時，與上述實施例1相同。 第13圖是表示設置蓋18的橫孔19與微窄通路12之位置關 係的透視斜視圖。圖中（a)爲最基本的構成。又，（b)是如第 8圖的（c)表示，顯示將2對微窄通路對設置在直行位置的場 合。如上述，相對於微窄通路2成複數個輻射狀設置的場合 ，使上述微窄通路對分別形成不同的橫剖面積，同時蓋1 8 係以可自由轉動地卡止而非熔融或焊接在排出管3的底部端 面16時，如第13圖（b)所示轉動蓋18時，可選擇適合橫孔19 的微窄通路1 2。並可僅以微窄通路對的數量進行階段性變 更。 經濟部智慧財產局員工消費合作社印製 再者，（a)的場合中，以迴轉式蓋18使橫孔19在不具微 窄通路12的位置移動可解除橫孔19與微窄通路12的嵌合， 具有禁止吐出之內栓的功能。 藉以上的構成，微窄通路12的形成是形成孔加工而非 溝加工，也可以藉模具成形可容易加工。同樣地蓋1 8的橫 孔加工可形成大於微窄通路1 2剖面積的孔，且無須精度因 此以鑽孔加工或模具成形皆可，其加工容易。 本紙張尺度適用中國國家標準（CNS ) A4規格（21〇Χ29<7公釐） -16- 573241 經濟部智慧財產局員工消費合作社印製 A7 B7五、發明説明（14) (實施例3 )

又，由於該管狀通路22的設置，具有可有效防止除管 路阻力之外，因容器本體1不注意加壓而噴出的效果。 (實施例4 ) 第17圖是表示本發明之點滴吐出流速控制容器的第4實 施例之排出管3的中央縱剖視圖，第1 8圖是表示排出管3之 底部端面1 6的底視圖。此排出管3安裝於容器本體1之上部 開口部7的方法是與實施例1相同。且上述3個實施例是表示 流速控制通路爲管狀的場合，但是該實施例是表示流速控

Description of the invention (彳) [Technical field to which the invention belongs] The present invention relates to the control of the droplet discharge flow rate when the contents (liquid) are discharged from the body by pressing the container body with pressure by hand, which can be discharged like droplets. container. In addition, the present invention relates to a quantitative metering flow rate control container having a discharge rate control mechanism and a quantitative metering container capable of measuring a certain amount. [Prior art] Until now, special bottles have been popularly used mainly for tin water containers, and their shapes are also widely distributed in the market. In addition, as for plastic bottles centered on lotion containers, although various types of containers are proposed as compared to PET bottles, from the viewpoints of waste reduction and resource reuse, there have already been used containers as supplement containers. popular. However, conventional containers have focused on the container body, and the design of the discharge port has a feeling of being discarded. That is to say, the Emperor ’s Seat sprays out of the container. The contents are J years old. Therefore, for example, when a large-capacity treasure bottle is used, the weight cannot be effectively discharged and it will overflow from the container, or the lotion will be replenished. When filling into a plastic bottle with a bag container, the bag container is accidentally squeezed and ejected from the discharge port, or the discharge of the discharge port is deviated from the intended direction due to the distortion of the container body, causing problems such as contamination of the surrounding area. Therefore, it is necessary to work on the structure of the discharge port so that the liquid contained in the container is not accidentally discharged from the container. In view of this, the applicant proposed a method in Japanese Patent Laid-Open No. 10-3333827 Technology for controlling the flow rate of liquid at the outlet.

Description of the invention (2) On the other hand, 'especially eye drops, etc., have containers necessary to discharge the contents from the liquid container in drops. In addition to eye drops, liquids that are necessary to be discharged in a small drop form a variety of cosmetics and food additives. The conventional drip discharge container has a structure in which a simple and small container discharge port represented by eye drops is formed, the liquid is stopped by the surface tension of the liquid, and the container body is pressed with a finger or the like to increase the internal pressure and squeeze out. In addition, in the case of a container for cosmetics or food additives, the discharge port simply forms the same small mouth as the eye drops. In this case, it is better to shake the container body than to squeeze the container body. However, from the experience of eye drops, it is difficult to control the force required to press the container body to discharge one drop. When not only one drop and two drops are squeezed out, the force must be performed.-'' ~. 一 .... τ fine-tuning . Therefore, the degree of freedom in selecting the container body material (the hardness and rigidity of the container) is low. Therefore, for example, it is extremely difficult to drip and discharge the contents from the flexible container body of the laminated tube. Only plastic or glass containers with appropriate hardness and rigidity must be used. In view of this, the drip discharge flow rate control container of the present invention provides a solution that can solve the above-mentioned conventional problems, and the drip discharge of the contents is extremely easy, and the container body has few restrictions, and it is easy to provide drip discharge that can use a variety of flexible containers. Drain liquid container. In addition, liquid containers such as lotions have been conventionally used in pump-type resin bottles. This upper part of the resin bottle container is equipped with a hand-pump type pump, and if necessary, the pump is discharged by hand. This pump is a so-called plunger pump. When the hand press part is pressed, the contents of the retention pump are discharged from the discharge port. Once the hand leaves, the paper size is adapted to the Chinese National Standard (CNS) A4 specification by the return spring. 210 X 297 mm) (Please read the precautions on the back before filling out this page),?

Description of the invention (3) (Please read the back first Please fill in this page again.) The structure that sucks the contents from the container body while pushing back the hand pressing part. There is usually a non-return ball inside the chestnut. This system forms a check valve to prevent the contents of the pump from once flowing back into the container body. A thin tube is provided at the lower end of the pump body so that the contents can be sucked up from the bottom of the container body. In addition, this container is mostly used for liquids with high viscosity, such as lotions and shampoos, to form extremely common containers. However, the return spring of the pump is made of metal or the like. Although a single material configuration is technically feasible, the problem of cost is not practically available. In addition, in a society with high environmental awareness, the problem of garbage has reached a level that cannot be ignored. In addition, since a check valve for preventing backflow is provided in the pump, the content stays in the tube between the pump and the discharge port to harden, and there is a problem that the hardened content is discharged during the subsequent discharge.

In addition to solving the above-mentioned conventional problems, the liquid container of the present invention can be composed of a single material. Provide a liquid container that prevents the contents of the discharge tube from being sucked into the container body and causes the contents to stay in the tube and harden. In addition, the liquids that had to be measured in the past were initially liquids such as pharmaceuticals, cosmetics, and even paints and lotions. Among medicines, most of them are measured in bottles or measuring cups. In addition, liquid containers, such as lotions, which are used more frequently than pharmaceuticals at one time, generally use bottle caps as measuring cups or pump-type synthetic resin bottles. The former is used after the measuring cup is removed from the container body, which can be measured freely according to the needs, which is not suitable for accurate measurement. And the latter is a bottle made of synthetic resin -6- This paper size applies the Chinese National Standard (CNS) A4 specification (21〇 > < 297 Gongchu) 573241 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ___ B7 V. Description of the Invention (4) The upper opening of the container body is equipped with a hand-pump type chestnut, and if necessary, press the pump to discharge the contents. The amount to be ejected by this one press is approximately constant. However, a container with a measuring cup is not suitable for accurate measurement because the content is squeezed out of the container in cooperation with the scale provided on the measuring cup. At the same time, the extrusion method may overflow or the cap may not be tight enough to make the container When dumping, there are problems such as leakage of contents. When the return spring of a pump-type bottle-in-bottle pump is made of metal, etc., although a single material configuration is technically feasible, there are actually cost problems. In addition, a check valve for backflow prevention is provided in the pump. Therefore, in the pipe from the pump to the discharge port, the contents will stay and harden, and there will be problems such that the hardened contents will be ejected when it is subsequently discharged. In view of this, in addition to solving the above-mentioned conventional problems, the liquid container of the present invention can be composed of a single material, not only has a simple structure, but also can prevent spitting out when the flow rate control is not paid attention to. At the same time, it can provide the contents of the spitting tube without causing the problem. The liquid container which is inhaled inside the container and causes the contents to stay in the tube to harden, and at the same time, it can provide a certain amount of liquid container with correct measurement.

[Embodiment] (Example 1) Figure 1 shows the droplet discharge flow rate with the droplet discharge liquid discharge port. A perspective view of the control container. The container body 1 is constituted by a discharge tube 3 having a discharge port 2 and a gland 4 which is fixedly pressed against the container body 1. The upper end of the gland 4 is prepared to prevent unused The cover 5 for discharging and protecting the discharge port 2 due to inattention. The cover 5 is suitable for the step 6 provided on the periphery of the upper end of the above-mentioned gland 4 to form a plurality of protrusions or grooves, respectively, to be maintained by a moderate pressing force. Figure 2 is an enlarged sectional view of the main part near the discharge port. The upper part of the bottle-shaped container body 1 has an opening 7 and a discharge pipe 3. The discharge pipe 3 carries a flange 8 (please read the precautions on the back before (Fill in this page) This paper size is applicable to Chinese National Standard (CNS) A4 (210 X297 mm) -10- 573241 A7 B7 V. Description of the invention (8) (Please read the precautions on the back before filling this page) container The upper end surface of the opening portion 7 of the main body 1 is fixed to the container main body 1 by a gland 4 and a screw bolt. The container main body 1 is formed of a relatively soft and flammable material made of synthetic resin. More specifically, polypropylene is used. Synthetic resin materials such as laminated tubes and composite films are preferred. The discharge tube 3 is made of hard synthetic resin, in order to fit the container body 1 ------------------ ---------- 一 ^ .—... The opening 7 is shaped as shown in FIG. 3 with a flange 8 and has a main discharge passage in the center (hereinafter, referred to as the main passage). 9 is a tubular member of 9. The main passage 9 is shown in the figure, the lower part is non-penetrating, the lower end is closed by the bottom 10, and the side wall near the bottom 10 is provided in a direction that runs straight with the main passage 9 A micro-section hole (hereinafter referred to as a "narrow narrow passage" as a flow rate control passage) (hereinafter referred to as a "narrow narrow passage" — a — * ——.—- ~… ... a…) 12. The narrow path 12 is closed by the surface tension of the liquid contained in the stolon or the phenomenon of thin tubules, or the field of the mixed gas sea is formed into a colored bell-shaped state-which is not acceptable under normal pressure ... Degree. It is best determined by its liquid surface tension or viscosity, but in the case of a low-viscosity fluid such as apricot, it is preferably 0.3 mm to 1.5 mm_. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and the narrow path 12 is formed to have a length of 3 meters in the discharge pipe. The cross section can be freely selected from circular, triangular, and quadrangular shapes, and the shape is not limited. The length of the narrow passage 12 is preferably a long shape that can stabilize (rectify) the outflow state of the contents at the exit of the passage. That is, when it is too short, it will spread at the exit of the passage, so that the opposite contents cannot effectively conflict with each other. The reason is as follows. As shown in FIG. 4, the narrow path 12 is provided at a relative position. As shown in Fig. 5, the contents (liquid) discharged from the narrow passage 12 to the main passage 9 conflict with the approximate center of the main passage 9, thereby making the discharge flow rate -11-This paper size applies to China National Standard (CNS) A4 specification (210 X 297 mm) 573241 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs V. Invention Description (9) 0 (zero). Therefore, the contents are not discharged from the discharge port 2 at a flow rate through the narrow passage 12. In addition, the smaller the diameter of the narrow passage 12 is, the more the content of the narrow passage 12 can be limited, but the main passage 9 needs to be filled with the content for a long time, and at the same time the external pressure acting on the container body 1 (Finger pressure) becomes dull. In other words, the content of the liquid droplets dripped from the discharge port 2 is adjusted as described below, and the magnitude of the force with which the container body 1 is pressed depends on the length of the pressing time, and the dripping control becomes extremely easy. And the dropping speed is based on the external pressure (the force pressing the container body 1) according to the passage velocity of the narrow path, but the dropping control can be changed by pressing the container body 1 time or force to change the narrow path. 12 effective opening area (aperture). In addition, the size of the opening area of the narrow passage 12 can be appropriately changed and balanced according to the degree of softness of the container body 1, thereby accurately matching the properties and dripping conditions of the contents in the storage container. When using the drip discharge flow rate control container of the first embodiment configured as described above, as shown in FIG. 6, when the container is poured with a finger to press the container body 1, the container body 1 is deformed as shown in the dotted line in the figure to make the container As the pressure rises, the contents (liquid) flow into the narrow passage 12 from the container body 1 as shown in FIG. 7, and are extruded from the narrow passage 12 toward the center of the main passage 9 as shown in FIG. 5 at the same speed. Spitting out conflicts so that once the speed is set to zero. Instead of spitting out rapidly from the discharge port 2, it can be connected to the inner wall of the main passage 9 by surface tension, and the dotted line in FIG. 7 indicates that the main passage 9 is slowly filled, and overflows and drops from the discharge port 2 after being filled. Because the discharge speed (flow rate) of discharge port 2 is 0 (zero), it will not be used (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -12- 573241 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (10) Spit out from the discharge port 2 through the narrow flow path 12 in the state, so the outflow of the content is extremely slow, even if it is not Even when the external pressure is applied to the container body i, the ejection from the discharge port 2 is prevented, and the drip amount can be finely adjusted very easily. That is, it is easy to measure the time of one drop, or it is easy to calculate the number of drops, and it is easy to spit. When the external pressure of the container body 1 is removed after the discharge, the amount of air sucked into the container body 1 is restored to the container body 1 by the restoring force of the container body, and the contents in the discharge path are simultaneously sucked into the container body 丨 in the main passage 9 The inner contents do not remain therein, and extremely good drainage of the discharge port 2 is obtained without remaining dripping. In addition, since no contents remain in the main passage 9, the main passage 9 does not flow out from the discharge port 2 even when the main passage 9 is not fully filled when external pressure is applied to the container body 1. As described above, the narrow path 12 is closed by surface tension or capillary phenomenon, or a so-called vapor lock state when mixed bubbles are formed. The path has a diameter that is not easy to pass under normal pressure. There is no residue in the suction in the narrow path 1. The diameter of the discharge port 2 may be a diameter at which the content does not remain dripping through the capillary phenomenon at normal pressure. For example, a low-viscosity liquid of water is preferably about 1.5 mm to 3 mm. However, it may be based on the properties of the content or The purpose of use of the container is appropriately changed. Alternatively, the inner diameter of the same discharge port 2 and the inner diameter of the main passage 9 are not required. Of course, it is also possible to form the elongated main passage 1 or vice versa to form a large main passage. In addition, it is possible to have one narrow passage 12, but at this time, it is necessary to have a means to zero the speed of the narrow passage 12 when it collides with the wall surface. Therefore, this paper is applicable to the National Standard (CNS) A4 specifications (210x297 public holidays) * one (please read the notes on the back before filling out this page) 573241 Printed by the Consumers' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _ B7 _ V. Description of the invention (^) Actually shown in Figure 8 It is better to set a plurality of relative positions shown in each figure. This is because the shorter the distance from the exit of the narrow passage 12 to the position where the flow velocity becomes zero, the more resistance will be generated in the flow path, which will prevent it from ejecting. When there are three or more narrow passages 12 as shown in Section 8 (b), it is sufficient to arrange the radial shapes that cause the contents ejected from all the narrow passages 12 to collide at substantially the center. (C) In the case of four narrow paths. When there are even a small number of narrow paths, a plurality of narrow path pairs shown in the same figure (c) may be arranged in parallel. In addition, for the narrow path 12, other configurations shown in FIG. 9 can be considered at the same time. That is, when the speed of the inflow direction from the narrow passage 12 is zero, when the content flowing in from the narrow passage 12 collides with the wall or the relatively flowing content, it includes a case where the direction of the strong flow is changed. For example, in Figure 9, (a) the content flowing in from the narrow passage 12 of the side wall 11 conflicts with the opposite inner wall, and (b) the conflict wall 13 is erected in the center of the bottom of the main passage 9, The content flowing into the narrow narrow passage 12 of the side wall 11 in the direction of the collision wall 13 conflicts with the wall. (C) The content flowing in from the narrow narrow passage 12 provided at the non-opposing position of the side wall 11 is at a non-right angle to the inner wall At this time, because the contents flow along the transition direction of the inner wall of the main passage 9, eddy currents will be generated in the main passage 9. (D) The narrow passage 12 is the same as the above-mentioned (c), and the wall 14 on the front side where the inflow has collided with the inflow content is provided in a straight direction. The number 1 in the figure is a vertical cross-sectional view, and 2 is a cross-sectional view of the position of the narrow passage. (E) a notch is formed at a position facing the lower corner of the discharge pipe 3 to form a narrow passage 12. At this time, as shown in (e) -2, the contents are distributed into the main passage 9 along the bottom surface. (E) -3 is a cross-sectional view of the position of the narrow passage. (0 is when the narrow path 12 is set up and down from the side wall of the relative position, (g) is above (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297mm) -14-573241 A7 B7 V. Description of the invention (12) (Please read the precautions on the back before filling this page) In the case of (b), the narrow path 12 is set up and down, (H) In the case where there is a narrow passage 1 2 that flows obliquely from the side wall 11 toward the bottom corner of the main passage 9 'and (I) shows that it has a micro inflow from the side wall 11 or the bottom face to the inner wall In the case of the narrow passage 1 2. In the case of (I), a collision wall 15 that does not flow upward when the contents collide with the inner wall is provided as shown in the figure. (Embodiment 2) Fig. 10 shows the present invention. A vertical longitudinal sectional view of a discharge pipe 3 of the second embodiment of the second embodiment of the discharge flow rate control container. The method for mounting the discharge pipe 3 on the opening 7 on the upper portion of the container body 1 is the same as that of the first embodiment. The structure of the narrow path 12 of Example 1 is easy to process. In Example 1, Although the diameter of the narrow passage 1 is preferably 1 mm, it is very difficult to process a hole with a diameter of 1 mm or less in the actual manufacturing process. Therefore, this embodiment is a problem that can improve the above embodiment 1. Ministry of Economic Affairs Printed by the Intellectual Property Bureau employee consumer cooperative, that is, as shown in Fig. 10, the main passage 9 of the discharge pipe 3 runs through the upper and lower ends, and the bottom end surface 16 is formed as shown in Fig. 11 to form a narrow passage 1 2 The groove 17 is provided with a cover 18 for fitting the bottom end surface 16. The cover 18 is provided with a lateral hole 19 having a cross-sectional area larger than that of the narrow passage 12 at a position suitable for the narrow passage 12 on the side. The cover 18 is embedded so that its inner bottom surface 20 (Fig. 12) is in close contact with the bottom end surface 16 of the discharge pipe 3, and welded or adhered tightly integrated parts are formed. In addition, the groove 17 is a tube closed by the inner bottom surface 20 of the cover 18 to form a closed section. A narrow path 12 is formed.

Also, the cross section can be freely chosen as circular, triangular, quadrangular, etc., without limiting its shape. Slightly narrow The length of the passage 12 is preferably a long shape that can stabilize (rectify) the content of the outflow passage to the outflow state. That is, because it will spread at the exit of the passage when it is too short, the effective conflict between the relative contents cannot be obtained. In use, the drip discharge flow rate control container of the second embodiment is the same as the first embodiment described above. Fig. 13 is a perspective perspective view showing the positional relationship between the horizontal hole 19 provided with the cover 18 and the narrow passage 12. (A) in the figure is the most basic structure. (B) shows a case where two pairs of narrow path pairs are provided in a straight position as shown in FIG. 8 (c). As described above, when the plurality of narrow passages 2 are arranged in a plurality of radial shapes, the narrow passage pairs are formed to have different cross-sectional areas, and the cover 1 8 is locked to rotate freely instead of being melted or welded. When the bottom end face 16 of the discharge pipe 3 is rotated, as shown in FIG. 13 (b), when the cover 18 is rotated, a narrow passage 12 suitable for the horizontal hole 19 can be selected. It can be changed in stages only by the number of narrow path pairs. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. (A) In the case of (a), the horizontal hole 19 can be moved at the position without the narrow path 12 by the rotary cover 18 to release the insertion of the horizontal hole 19 and the narrow path 12. Closed, it has the function of preventing the internal plug from spitting out. With the above configuration, the narrow passage 12 is formed by forming a hole instead of a groove, and it can also be easily processed by a mold. Similarly, the processing of the horizontal hole of the cover 18 can form a hole larger than the cross-sectional area of the narrow passage 12 without the need for precision. Therefore, it can be formed by drilling or molding, and the processing is easy.

Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Figure 25 is an enlarged sectional view of the main parts near the outlet. An upper portion of the bottle-shaped container body 1 is an opening 7 and includes a discharge pipe 3. The discharge tube 3 places the flange 8 on the end surface of the opening portion 7 of the container body 1, and presses the cover 4 to fix the container body 1 with screws. The container body 1 is formed of a relatively soft and flexible material such as a synthetic resin. More specifically, synthetic resin materials such as polypropylene, polyethylene, and laminated pipes can be suitably used. A cover member 35 covering the lower portion of the lower portion of the flange 8 of the discharge pipe 3 is provided to isolate the discharge pipe 3 in the container body, and the lower end thereof is inserted into the thin pipe 36. A space 37 having a predetermined capacity is formed between the cover member 37 and the discharge tube 3, and the space 37 communicates with the container body by a single thin tube 36. The lower end of the thin tube 36 reaches the bottom of the container body 1 as shown in Fig. 24. The paper size used to draw the contents from the bottom is in accordance with Chinese National Standard (CNS) A4 specifications (210X 297 mm) -22- 573241 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ___ B7_ V. Description of the invention (2〇 With the above configuration, the hydraulic pressure in the container does not directly act on the narrow passage described later, the internal pressure of the container is attenuated by the pipe resistance of the thin tube 36, and the inner space 37 provided with the cover member 35 (will not stay in the normal state) Contents) Even if the internal pressure is rapidly increased due to careless pressing of the container body 1, the contents are not ejected from the discharge port 33. In addition, when the container body 1 is inverted or poured, the lower end of the thin tube 36 is higher than the liquid surface, so that the pressure of the content does not act on the narrow path, and does not eject or drag. The discharge pipe 3 is a tubular member having a flange 8 and a central passage (hereinafter referred to as a main passage) 9 in the shape of an opening 7 suitable for a container as shown in FIG. 26 (a). The main passage 9 is formed in a non-penetrating state at the upper end as shown in FIG. The discharge port cover 34 is rotatably inserted to form a position that can match the inlet 38 and the discharge port 2 corresponding to the discharge path. Therefore, turning the discharge port cover 34 when not in use can release the correspondence between the two and prevent the contents from being discharged. On the other hand, the lower end is closed by the bottom cover 18. In addition, a minute cross-section hole (hereinafter referred to as a narrow path) 12 is provided as a narrow path in a direction in which the discharge pipe 3 and the bottom cover 18 are connected in a straight line with the main path 9 described above. The dimensions and the like of the narrow channel 12 are the same as those of the first embodiment. As shown in FIG. 26 (b), a groove 17 is formed on the lower end surface 16 of the discharge pipe 3 which is the same as the second embodiment, and closed with a bottom cover 18. Method of forming a tubular passage 12. The arrangement and effects of the tubular passages 12 are the same as those of the first embodiment. When the liquid container of the seventh embodiment configured as described above is used, as shown in FIG. 27, when the pressure of the container body 1 is pressed with a finger, the internal pressure of the container rises due to the deformation of the container body 1, and the contents (liquid) As shown in Figure 28, from the application of this paper size @National Standard (CNS) A4 specifications (210X297 mm) (Please read the precautions on the back before filling this page) 573241 A7 ___B7_ V. Description of the invention (21) (Please Read the precautions on the back before filling in this page) The bottom of the container body 1 enters the space of the cover member 35 through the thin tube 36 and flows into the narrow passage 12 while spitting out at the same speed to conflict with each other so that the speed once formed is zero (zero). It can prevent it from spitting out from the discharge port 3 quickly, can contact the inner wall of the main passage 9 by surface tension, and slowly fill the main passage 9 as shown by the dotted line in FIG. 33 spit out. Once the discharge speed (flow rate) immediately before the discharge port 33 becomes 0 (zero), the contents of the discharge port 33 flow out extremely slowly, and even if an unintended external pressure acts on the container body 1, it will not be ejected from the discharge port 33 , Can be easily adjusted finely. In addition, when the hand is removed from the container body 1 after the discharge is completed, a negative pressure is formed in the container body due to the elastic restoring force of the container body 1. In this way, as shown in Fig. 29, the contents in all the paths from the discharge port 33 to the thin tube 36 can be returned to the container body 1 by its negative pressure. In the case of a tube with a diameter of such a narrow path, the liquid may be trapped therein due to the capillary phenomenon. However, in this embodiment, the negative pressure in the container body can prevent the liquid from remaining inside the container body 1 and can return to the container body 1. At this time, the lower end of the thin tube 36 corresponds to the equilibrium state of the atmospheric pressure and the internal pressure of the container, and only a slight amount of content is left in the capillary phenomenon. As a result of printing by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, most of the discharge path from the discharge port 33 to the lower end of the thin tube 36 does not retain the contents under normal conditions, so the contents in the container body 1 are handled by hand. When the container body 1 is pressed, it takes a certain amount of time to flow to the discharge port 33. Therefore, when an inadvertent external pressure acts on the container body 1, the contents are not ejected. In addition, the content remaining in the discharge path will not harden, so once it is used again, the content fixed on the discharge port 33 will not be ejected. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297). ^) 573241 A7 B7 V. Description of Invention (22). In addition, liquid leakage can be prevented. (Please read the precautions on the back before filling in this page.) Furthermore, the diameter of the discharge port 33 should be the diameter that the content will not stagnate due to capillary phenomenon under normal pressure. For example, the low viscosity liquid of water is 1.5mm. It is preferably about 3 mm, but may be appropriately changed according to the properties of the contents or the purpose of use of the container.

The structure of the plug 27 is the same as that of the above-mentioned Embodiment 6 as shown in Fig. 22 (a). (Embodiment 10) Fig. 32 is a perspective view showing a quantitative metering flow rate control container of the present invention. The discharge port 2 on the upper portion of the container body 1 is constituted by a pressing cap 4 and a measuring container 42 which are fixed to the container body 1 with a discharge pipe 3. Fig. 33 is an enlarged sectional view of a main part near the measuring container. An upper portion of the bottle-shaped container body 1 is an opening 7 and includes a discharge pipe 3. The configuration of the discharge pipe 3 and the container body 1 is the same as that of the seventh embodiment, except that the discharge port 2 faces upward. The discharge pipe 3 has a tubular portion 43 having a predetermined length as shown in Fig. 33. The discharge port 2 is formed at the front end, and the measuring container 42 is inserted with the tubular portion 43 as an axis. The upper end of the measuring container 42 is positioned higher than the discharge port 2. Fig. 34 (a) is a central vertical sectional view of the discharge pipe 3 and (b) is a bottom view. When the quantitative measuring flow rate control container constituting the tenth embodiment described above is used, as shown in FIG. 35, when the pressure of the container body 1 is pressed with a finger, the container body 1 is deformed as shown by the lines to increase the internal pressure of the container, so that The content (liquid) is shown in FIG. 36 from the bottom of the container body 1 through a thin tube to enter the space of the cover member 35 and flows into the narrow passage 12 as shown in FIG. 5 toward the center of the main passage 9 from the narrow passage 12 While extruding, spit out conflicts at the same speed to reduce the speed once to 0 (zero). It does not spit out from the discharge port 2 quickly. It can adhere to the inner wall of the main passage 9 by surface tension and overflow and then spit out from the discharge port 2. According to the conventional method, the paper is discharged from the discharge pipe 43 protruding from the measuring container. Applicable to China National Standard (CNS) A4 specification (210X297mm) ~ (Please read the precautions on the back before filling this page) 573241 A7 B7 V. Description of the invention (24) f Please read the precautions on the back before filling this page In the case of contents, as shown in FIG. 37, there is a danger of ejection when it is ejected toward the opening D of the measuring container 42, so that the ejection outlet 2 must collide with the inner wall of the measuring container 42. However, in the quantitative metering flow rate control container of the present invention, once the discharge speed (flow rate) is reduced to 0 (zero) in front of the discharge port 2, the contents will not be discharged from the discharge port 2 at a flow rate through the narrow path 12 to cause the contents to flow out. It is extremely slow, and even when an inadvertent external pressure acts on the container body 1, it does not eject from the ejection D2, and it is extremely easy to finely adjust the ejection amount. That is, it is easy to adjust the discharge amount when it is discharged slowly. As shown in Fig. 36, there is no danger of ejection even if the opening of the measuring container 42 faces upward. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. As shown in FIG. 36, the contents discharged from the outlet 2 overflow into the measuring container, and the water level WL higher than the height of the outlet 2 is raised. In this state, the force of the hand holding the container body 1 is loosened, and a negative pressure is formed in the container body 1 by the restoring force of the container body 1. In this way, as shown in FIG. 38, the negative pressure can be used to suck the contents of the water level higher than the discharge port 2 into the discharge port 2 again, and the thin tube 36 can prevent the contents in all the channels from flowing back into the container body 1. The water level WL is determined by the height of the outlet 2. In the case of a tube with a diameter of such a narrow path, the liquid will be trapped due to the capillary phenomenon. However, in this embodiment, the negative pressure of the container body 1 can prevent the liquid from flowing back into the container body 1. As a result, it is possible to maintain a constant amount of the content in the stagnant measuring container (residual) at all times, and it is not affected by the discharge amount or the discharge speed from the container body 1. In addition, in the discharge path from the discharge port 2 to the lower end of the thin tube 36, the content is not retained under normal conditions. Therefore, the content after the measurement is applied to the paper standard of China National Standard (CNS) A4 ( 210X297 mm) -27- 573241 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 __ B7 _V. Description of the Invention (25) Even when the container is dumped, the excess amount will not flow out of the spout 2 when it is discharged. In addition, the contents do not remain hardened in the discharge path. Therefore, once the product is used again after use, the contents of the discharge port 2 will not be ejected, etc. In addition, the diameter of the discharge port 2 is kept at normal pressure to prevent the contents from being hardened. The diameter of the degree of dripping due to the capillary phenomenon is sufficient. For example, a low-viscosity liquid such as water is preferably about 1.5 mm to 3 mm, but it can be appropriately changed according to the properties of the contents and the purpose of use of the container. (Embodiment 11) Figure 39 is a perspective view showing a quantitative metering flow rate control container according to a second embodiment of the present invention. The basic method of discharging the contents and the path of the contents of the container body 1 is the same as that of the tenth embodiment.

In other words, a substantially lower half of the tubular portion 43 of the discharge pipe 3 latches the thread 44, and the measuring container 44 is similarly formed with a thread 45 suitable for the thread 44 of the tubular portion 43. The upper end of the threaded portion 45 of the measuring container 42 is formed into a cap shape having an opening at the center, and a tubular portion 43 is inserted into the opening. An O-ring 46 is provided at a portion of the opening that is connected to the tubular portion 43 to prevent leakage of the contents of the measuring container. With the above configuration, the rotating measuring container 42 is formed to be freely movable up and down. The measurement quantity in the measurement container can be determined by the height h from the bottom of the measurement container 42 to the discharge port 2 or the water level WL. Therefore, as shown in Figure 40, the state where the measuring container 42 is raised to the upper limit forms the least quantitative basis, such as page 41 (please read the precautions on the back before filling this page) The paper size applies the Chinese National Standard (CNS) A4 specifications (210X 297mm) -28- 573241 A7 B7 V.
