Description
本發明係關於吐泡沫用泵之吐出噴頭。The present invention relates to a discharge nozzle for a pump for spitting foam.
已有一種混合容器體內之液體與空氣而起泡沫並吐出(discharge)泡沫之吐泡沫用泵容器被提案。(例如參照專利文獻1)There has been proposed a pump container for spitting foam which foams a liquid and air in a container and discharges the foam. (For example, refer to Patent Document 1)
上述吐泡沫泵容器，係使設在覆蓋容器的開口部之蓋體內部的大直徑之空氣用圓柱(cylinder)與小直徑的液體用圓柱設成同心圓狀的雙層圓柱，以及，密接在此雙層圓柱內壁，並藉由空氣用活塞和液體用活塞同時上下動地形成空氣室部與液體室部，且活塞體藉彈簧被偏壓在上死點側之狀態下而貫通蓋體頂面中央部並在上方延伸，且在其上端部被固著成為泡沫通路之中空的噴嘴體。The spit foam pump container is a double-decked cylinder in which a large-diameter air cylinder provided inside the lid body covering the opening of the container and a small-diameter liquid cylinder is concentrically formed, and is closely attached thereto. The inner wall of the double-layered cylinder is formed by the air piston and the liquid piston simultaneously forming the air chamber portion and the liquid chamber portion, and the piston body is biased to the top dead center side by the spring to penetrate the cover body. The central portion of the top surface extends upwardly and is fixed at its upper end as a hollow nozzle body of the foam passage.
該噴嘴體具有：縱筒部份；及，在此縱筒部份的上端前面使一端開口朝向前方延伸之橫筒部份；如此所成，並使橫筒部份的前端開口當作吐出口而開口。The nozzle body has: a longitudinal tube portion; and a horizontal tube portion extending toward the front end of the upper end of the longitudinal tube portion; the end portion of the horizontal tube portion is formed as a spout And the opening.

以往的吐出泡沫用泵容器，一般係將一邊的手掌位於吐出口之前下方，而藉另一邊的手按壓噴嘴體上面並藉上下動以使泡沫噴出，但泡沫係從吐出口比較直線地朝前方被噴出，並以本身重量而形成拋物線落下至下方。另一方面，如須以單手來操作之情形下，例如，收容液是幼兒用的清潔劑等時，則必須以單手抱著幼兒而實施泡沫之噴出。在此情況下，一般為使單手的手掌位於吐出口前方，而以拇指按壓噴嘴體上面以使泡沫噴出，但已知的吐泡沫用容器其泡沫會朝前方如飛出地噴出，因此有不能順利地噴出至接近噴嘴體的手掌上之缺點存在。In the conventional pump container for discharging foam, generally, the palm of one side is located below the discharge port, and the hand of the other side presses the top of the nozzle body and moves up and down to eject the foam, but the foam is linearly forward from the discharge port. It is ejected and forms a parabola with its own weight and falls down to the bottom. On the other hand, in the case where it is necessary to operate with one hand, for example, when the containing liquid is a cleaning agent for children, it is necessary to carry out the ejection of the foam by holding the child with one hand. In this case, generally, the palm of one hand is placed in front of the discharge port, and the top of the nozzle body is pressed by the thumb to eject the foam. However, the known foaming container has a foam which is ejected toward the front as if it is flying out. The shortcomings that cannot be smoothly ejected to the palm of the hand near the nozzle body exist.
本發明係鑑於上述之點而所完成，其提案以單手可正確地吐出泡沫之吐泡沫用泵之吐出噴頭。又，其可確實地防止以單手在噴出泡沫時手指被噴出頭所夾住，而使用方便之吐泡沫用泵之吐出噴頭。The present invention has been made in view of the above points, and it is proposed to discharge the discharge nozzle of the foam spit foam pump with one hand. Further, it can surely prevent the finger from being caught by the ejection head when the foam is ejected with one hand, and the ejection nozzle of the pump for spitting foam which is convenient to use.
本發明之吐出噴頭(discharge head)係構成安裝於容器體所使用之吐泡沫用泵的一部份。吐泡沫用泵係使容器體內的液體與空氣混合而吐出泡沫之構成，而本發明以具有可滿足此要件之以往的眾所周知之構造為對象者。容器體可使用由本體部使口頸部起立者，而藉在口頸部嵌合安裝蓋，以閉塞口頸部上端開口並安裝吐泡沫用泵。The discharge head of the present invention constitutes a part of a pump for foaming which is attached to a container body. The spitting foam pump is configured such that the liquid in the container body is mixed with air to discharge the foam, and the present invention is directed to a conventionally known structure which satisfies the requirements of the present invention. The container body can be used by erecting the neck portion by the body portion, and a cap is fitted to the neck portion to close the upper end opening of the mouth and neck portion and to install a spit foam pump.
本發明之吐出噴頭係被使用在此種吐泡沫用泵，特別是以單手即可容易且確實地操作之構成。本發明之吐出噴頭，具有縱筒及吐出噴嘴。縱筒係嵌著在主桿(stem)之上端而藉由吐出噴嘴而吐出來自主桿的泡沫，雖然本發明如使用形成圓筒狀之縱筒者較佳，但本發明並不限於圓筒狀者。又，吐出噴嘴係在縱筒內使基端開口朝向側方延伸所設置，同時，使前端當作吐出口而開口之橫筒形態者。The discharge nozzle of the present invention is used in such a pump for foaming, and in particular, it can be easily and reliably operated with one hand. The discharge nozzle of the present invention has a vertical cylinder and a discharge nozzle. The vertical cylinder is embedded in the foam at the upper end of the main stem and spits out the apron by the discharge nozzle. Although the present invention is preferably used to form a cylindrical vertical cylinder, the present invention is not limited to the cylinder. Shape. Further, the discharge nozzle is provided in a vertical cylinder in which the base end opening is extended toward the side, and the front end is formed as a discharge port.
為了達成上述目的，本發明使吐出噴嘴的流路之縱剖面形狀係構成為橫長形狀，同時，在吐出噴嘴的前端部下部設置切缺開口部，且使吐出噴嘴流路呈水平或朝向前端構成逐漸上升，由此則可順利地從吐出噴嘴吐出泡沫，而被吐出的泡沫則不會朝向前方噴出而可容易地朝下方吐出。In order to achieve the above object, in the present invention, the longitudinal cross-sectional shape of the flow path of the discharge nozzle is formed into a horizontally long shape, and a slit opening portion is provided in a lower portion of the tip end portion of the discharge nozzle, and the discharge nozzle flow path is horizontal or toward the front end. Since the configuration is gradually increased, the foam can be smoothly discharged from the discharge nozzle, and the discharged foam can be discharged to the front without being discharged toward the front.
上述橫長形狀是指長軸於水平狀態之橫長的橢圓形狀或橫長的矩形狀，而縱橫之比率雖然未被特別限定，但例如，可為縱：橫＝2：5~2：3程度則較為適當，具體而言，如採用縱2mm×橫5mm~縱10mm×橫15mm程度之縱橫比較佳。又，切缺開口部係使吐出噴嘴前端部之底壁部份呈開放之形態，或使吐出噴嘴前端部之底壁部份及所相接的兩側壁下部呈開放之形態。因此，被穿設切缺開口部的部份其兩側壁也一定存在有上部之形態。切缺開口部之具體形態，可採用使兩側壁前端部下部各別切缺開放成曲線狀者，同時以和兩側壁的開放部份相連續之底壁前端部開放之形態者為佳。前述曲線狀，係自吐出噴嘴前端面至底壁下面之圓弧狀形態，而採用在上方凸出或在下方凸出之形態者均可。又上述吐出噴嘴流路之形態基本上雖然被舉出自和縱筒的連結部位朝向前端呈水平或傾斜上升之形態，但自連結部位朝向前端彎曲上升，或者起初在水平狀態而從途中傾斜上升或彎曲上升，如此者亦可。The horizontally long shape refers to a horizontally long elliptical shape in the horizontal state or a horizontally long rectangular shape, and the ratio of the vertical and horizontal directions is not particularly limited, but may be, for example, vertical: horizontal = 2: 5 to 2: 3 The degree is more appropriate. Specifically, it is better to use the vertical and horizontal dimensions of 2 mm × 5 mm, 10 mm, and 15 mm. Further, the opening portion is formed such that the bottom wall portion of the tip end portion of the discharge nozzle is opened, or the bottom wall portion of the tip end portion of the discharge nozzle and the lower portion of the two side walls that are in contact with each other are opened. Therefore, the portion of the portion through which the opening portion is cut and notched must have an upper portion. In the specific form of the opening portion, it is preferable that the lower end portions of the front end portions of the two side walls are opened and curved, and the front end portion of the bottom wall continuous with the open portions of the both side walls is preferably opened. The curved shape is an arc shape of the front end surface of the discharge nozzle to the lower surface of the bottom wall, and may be a shape that protrudes upward or protrudes downward. Further, the form of the discharge nozzle flow path is basically a form in which the connection portion from the vertical tube is horizontally or inclinedly inclined toward the distal end. However, the connection portion is curved toward the distal end, or is initially inclined from the middle in a horizontal state. Or bending up, so can be.
又，為了更確實發揮上述之目的，也可構成使吐出噴嘴的流路之內徑朝向下流側擴開者。Further, in order to more reliably achieve the above object, the inner diameter of the flow path of the discharge nozzle may be extended toward the downstream side.
流路之擴開，只要其縱剖面積呈變大之狀態者各種形態均可被採用，例如，自縱筒連結部位之流路基端部使直徑逐漸變大形成者亦可，或自流路途中使直徑逐漸變大者亦可，或者設置推拔部或段部而急遽使直徑變大者均可。又，擴徑可為使寬度或長度變大之情形，或使長寬兩邊均變大之情形均可。又流路之擴開程度並未被特別限定，但一般如考慮此種吐泡沫用泵之大小，則以內徑面積比2~5倍程度者較為適當，而當然其並不被限定於此。此種吐泡沫用泵的大小其在某程度被受限，隨著此一限制，主桿、縱筒及吐出噴嘴之直徑等也某種程度被受限，因此，上述流路之擴開程度也比較受限，結果，如只有吐出噴嘴流路之擴開則難以得到充分之效果，而如混合上述形態之吐出噴頭則可更發揮其效果。The expansion of the flow path may be employed in various forms as long as the longitudinal sectional area thereof is increased. For example, the end portion of the flow path from the longitudinal tube connection portion may be gradually increased in diameter, or may be formed on the way from the flow path. It is also possible to gradually increase the diameter, or to provide a push-out portion or a segment and to make the diameter larger. Further, the diameter expansion may be a case where the width or the length is increased, or both the length and the width may be increased. Further, the degree of expansion of the flow path is not particularly limited. However, in general, considering the size of the pump for spitting foam, the inner diameter area is preferably 2 to 5 times, and it is of course not limited thereto. The size of the pump for spitting foam is limited to some extent. With this limitation, the diameters of the main rod, the vertical cylinder and the discharge nozzle are also limited to some extent, and therefore, the degree of expansion of the flow path is As a result, it is difficult to obtain a sufficient effect even if only the discharge nozzle flow path is expanded, and the effect can be further exerted by mixing the discharge nozzle of the above-described form.
為了防止以單手操作本發明之吐出噴頭時發生之不方便，也可在前述吐出口下方的前面設置手指接觸面。當以單手操作時，如上述，以拇指壓下吐出噴頭上面，使張開的手掌位於吐出口前方下方，將接近泵之食指夾在吐出噴頭與安裝蓋時，則有時不能確保充份的吐出量。為了防止此一不方便，則以設有手指接觸面者較佳。藉使此手指接觸面抵接食指的側面時，則可自然地將手的位置導至以單手接受泡沫之狀態，且可防止夾住手指。手指接觸面之形狀為板狀且只要可抵接食指的側面之大部份的大小者即可，但如採用配合食指的形狀而中央部朝向後方突出彎曲之板狀形態者則更佳。In order to prevent inconvenience when the discharge head of the present invention is operated by one hand, a finger contact surface may be provided in front of the lower side of the discharge port. When operating with one hand, as described above, press the top of the discharge head with the thumb so that the open palm is located below the front of the discharge port, and when the index finger close to the pump is clamped between the discharge nozzle and the mounting cover, the filling may not be ensured. The amount of spit. In order to prevent this inconvenience, it is preferable to provide a finger contact surface. When the finger contact surface abuts against the side of the index finger, the position of the hand can be naturally guided to the state of accepting the foam with one hand, and the finger can be prevented from being pinched. The shape of the finger contact surface is a plate shape and may be a large part of the side surface of the index finger. However, it is more preferable to adopt a plate shape in which the center portion is curved toward the rear in accordance with the shape of the index finger.
又，本發明之吐出噴頭也可在其上面設置防滑部。以單手操作時具有通常手部大小的人其拇指之前端部份可到達吐出噴頭上面前部係一般者，因此，在吐出噴頭的上面前部如設置防滑部則較佳。當然如考慮通常的操作而在吐出噴頭上面之廣範圍設置防滑部亦可。防滑部之具體形態，可為藉施加凹凸加工而形成。凹凸之形態可採用各種形態，如平行排列之突條形態，或使小突部分散在既定平面上之形態，或其他各種形態均可被採用。Further, the discharge nozzle of the present invention may have an anti-slip portion provided thereon. A person having a normal hand size when operating with one hand can reach the front part of the ejection head on the front end portion of the ejection head. Therefore, it is preferable to provide an anti-slip portion on the upper front portion of the ejection head. Of course, it is also possible to provide an anti-slip portion over a wide range of the discharge nozzles in consideration of normal operations. The specific form of the anti-slip portion can be formed by applying uneven processing. The shape of the concavities and convexities may be in various forms, such as a rib shape arranged in parallel, or a form in which the bulging portion is scattered on a predetermined plane, or other various forms may be employed.
又，在上面設置手指接觸用之凹部者亦可。如設有該凹部時，為使拇指可簡單位於吐出噴頭上面之適當位置為目的時，具體而言則可在上面中央部或自上面中央部延伸而設在後方之凹部的構成。凹部的深度並未特別受限，但以1mm至數mm程度較妥。當然也可在此凹部內併用上述防滑部。Further, it is also possible to provide a recess for finger contact on the upper surface. When the concave portion is provided, in order to make the thumb easily located at an appropriate position on the discharge head, specifically, it may be configured to extend in the upper center portion or the concave portion provided in the rear center portion from the upper center portion. The depth of the recess is not particularly limited, but is preferably from 1 mm to several mm. Of course, the above-mentioned anti-slip portion can also be used in this recess.
本發明之第1手段係，安裝在容器體上方，在上方加壓狀態下可壓下突出之主桿的上端而嵌入吐出噴頭，使吐出噴頭上下動而從吐出口吐出泡沫，如此所構成之吐泡沫用泵的吐出噴頭，其具有：嵌入在主桿11的上端之縱筒12；及，使基端開口在該縱筒12內，同時，使前端構成為吐出口a之吐出噴嘴15，且將吐出噴嘴15的流路p之縱剖面形狀形成為橫長形狀，同時，在吐出噴嘴15的前端部下部設置切缺開口部17，且使吐出噴嘴15之流路p構成水平或前端逐漸上升狀。According to a first aspect of the present invention, in the upper side of the container body, the upper end of the protruding main rod can be pressed under the upper pressurized state, and the discharge head can be inserted, and the discharge head can be moved up and down to discharge the foam from the discharge port. a discharge nozzle for a spit foam pump, comprising: a vertical tube 12 that is fitted into an upper end of the main rod 11; and a base end that is opened in the vertical tube 12, and a tip end that is configured as a discharge nozzle 15 of the discharge port a, Further, the longitudinal cross-sectional shape of the flow path p of the discharge nozzle 15 is formed into a horizontally long shape, and the cutout opening portion 17 is provided in the lower portion of the tip end portion of the discharge nozzle 15, and the flow path p of the discharge nozzle 15 is formed horizontally or at the front end. Ascending.
本發明之第2手段係，在前述第1手段中，吐出噴嘴15的流路p之內徑係朝向下流側擴開。According to a second aspect of the present invention, in the first aspect, the inner diameter of the flow path p of the discharge nozzle 15 is expanded toward the downstream side.
本發明之第3手段係，在前述第2手段中，前述吐出噴嘴15的內徑係藉由推拔部16或段部21所擴開。According to a third aspect of the present invention, in the second aspect, the inner diameter of the discharge nozzle 15 is expanded by the push-out portion 16 or the segment portion 21.
本發明之第4手段係，在前述第1至第3手段之任一手段中，前述切缺開口部17係使兩側壁前端部下部各別切缺開放成曲線狀，同時，使和兩側壁之開放部份連結之底壁前端部開放。According to a fourth aspect of the invention, the cutting opening portion 17 is configured such that the lower end portions of the front end portions of the two side walls are not cut and opened in a curved shape, and the two side walls are formed. The front end of the bottom wall of the open part is open.
本發明之第5手段係，在前述第1至第4手段之任一手段中，前述吐出噴嘴15的流路p之縱剖面形狀係橫長矩形狀。According to a fifth aspect of the present invention, in the apparatus according to any one of the first to fourth aspect, the longitudinal cross-sectional shape of the flow path p of the discharge nozzle 15 is a horizontally long rectangular shape.
本發明之第6手段係，在前述第1至第5手段之任一手段中，在前述吐出噴嘴下方的前面部設有手指接觸面f。According to a sixth aspect of the present invention, in any of the first to fifth aspect, the finger contact surface f is provided on a front surface portion below the discharge nozzle.
本發明之第7手段係，在前述第1至第6手段之任一手段中，在上面設有防滑部20。According to a seventh aspect of the present invention, in any of the first to sixth aspects, the anti-slip portion (20) is provided on the upper surface.
本發明之第8手段係，在前述第1至第7手段之任一手段中，在上面設有手指接觸用凹部13c。According to an eighth aspect of the present invention, in any one of the first to seventh aspects, the finger contact recessed portion 13c is provided on the upper surface.
本發明之吐出噴頭1，由於使吐出噴嘴15的流路p之縱剖面形狀形成為橫長形狀，同時，在吐出噴嘴15之前端部下部設有切缺開口部17，且將吐出噴嘴15的流路p構成呈水平或朝前端逐漸上升，因此，其具有可以單手非常容易且確實地操作之優點。In the discharge nozzle 1 of the present invention, the longitudinal cross-sectional shape of the flow path p of the discharge nozzle 15 is formed into a horizontally long shape, and the cutout opening portion 17 is provided in the lower portion of the end portion before the discharge nozzle 15, and the discharge nozzle 15 is provided. The flow path p is formed to be horizontal or gradually rises toward the front end, and therefore has an advantage that it can be operated very easily and surely with one hand.
又，如使吐出噴嘴15的流路p之內徑構成朝下流側擴開時，則以單手的操作更可容易地確實實施，特別是如構成藉由推拔部16或段部21而使前述吐出噴嘴15的內徑擴開時，則可急遽地使流路擴開而大幅度地減低流速，如此而可更增加該效果。Further, when the inner diameter of the flow path p of the discharge nozzle 15 is expanded toward the downstream side, it can be easily performed with one-hand operation, and in particular, by the push-out portion 16 or the segment portion 21 When the inner diameter of the discharge nozzle 15 is expanded, the flow path can be rapidly expanded to greatly reduce the flow velocity, which can further increase the effect.
又，前述切缺開口部17，係使兩側壁前端部下部各別切缺開放成曲線狀，同時，使和兩側壁之開放部份連結之底壁前端部開放，則可防止在吐出噴嘴15內發生殘液，並可在曲線狀切缺部份削落附著在手指尖之泡沫，該時手指尖並不會有受傷之虞。Further, the cut-and-open opening portion 17 is formed such that the lower end portions of the front end portions of the both side walls are opened and opened in a curved shape, and the front end portion of the bottom wall that is connected to the open portions of the both side walls is opened, so that the discharge nozzle 15 can be prevented from being opened. Residual liquid is generated inside, and the foam attached to the tip of the finger can be cut off in the curved cut portion, and the finger tip does not have any injury.
又，在吐出噴嘴15下方之前面部設有手指接觸面f時，以單手操作時手指則不會夾在吐出噴頭1與安裝蓋10或容器體之間，而且僅使食指之側部抵接，即可自動地將手配置至單手操作之既定位置，有此等優點。Further, when the finger contact surface f is provided on the face before the discharge nozzle 15, the finger is not caught between the discharge head 1 and the attachment cover 10 or the container body when the one hand is operated, and only the side portion of the index finger is abutted. , you can automatically configure your hand to the established position of one-handed operation, which has these advantages.
在吐出噴頭1的上面如設有防滑部20時，其特別對以單手操作時可有效，對以比較不自然的形狀在吐出噴頭上面延伸之拇指也不會滑動而可確實地壓下吐出噴頭，而有可更容易實施吐出泡沫操作之優點。When the anti-slip portion 20 is provided on the upper surface of the discharge nozzle 1, it is particularly effective for one-hand operation, and the thumb extending over the discharge nozzle in a relatively unnatural shape does not slide and can be reliably pressed and discharged. The nozzle has the advantage that the ejection foam operation can be more easily performed.
又如在吐出噴頭1上面設有手指接觸用之凹部13c時，則拇指不會接觸至該吐出噴嘴15或其上面前部等不適當的位置，而可確實地容易壓下上面中央部之適當位置。Further, when the concave portion 13c for finger contact is provided on the upper surface of the discharge head 1, the thumb does not come into contact with the discharge nozzle 15 or the front portion thereof at an inappropriate position, and the center portion of the upper portion can be reliably pressed. position.
以下，參照圖式說明本發明之實施形態。Hereinafter, embodiments of the present invention will be described with reference to the drawings.
圖1表示採用本發明之吐出噴頭1的吐泡沫用泵A之一例，圖2至圖5各別表示安裝在此泵A之吐出噴頭1。吐泡沫用泵A，係在容器體2的口頸部3藉嵌合安裝蓋10而固定。又，在貫通安裝蓋10的頂部，於上方加壓狀態下可壓入突出之主桿11的上端而嵌入吐出噴頭1。又，在容器體2內，垂設由圓柱構件等所構成的眾所周知形態之泡沫形成吐出機構，且藉由使吐出噴頭1上下動作，則可自吐出噴頭1之吐出口a吐出泡沫。Fig. 1 shows an example of a foaming pump A using the discharge head 1 of the present invention, and Figs. 2 to 5 each show a discharge nozzle 1 attached to the pump A. The foaming pump A is fixed to the neck portion 3 of the container body 2 by fitting the cover 10. Further, the discharge head 1 is fitted into the top end of the main rod 11 which is protruded from the top of the mounting cover 10 by being pressed into the upper end of the protruding main rod 11. Further, in the container body 2, a foam forming discharge mechanism of a known configuration including a cylindrical member or the like is suspended, and by discharging the discharge head 1 up and down, the foam can be discharged from the discharge port a of the discharge head 1.
吐出噴頭1，係在主桿11的上端液密地嵌入圓筒狀之縱筒12而被固定。又，縱筒12自蓋筒13之圓板狀的頂壁部13a之裏面中央部所垂設，且自此頂壁部13a的周緣部垂設周壁部13b，如此而構成蓋筒13。自頂壁部13a之中央部跨至後端部凹設有可掛手指之凹部13c。又，在周壁部13b和縱筒12之間於左右及後部各別懸吊有加強肋14。The discharge head 1 is fixed to the cylindrical vertical tube 12 in a liquid-tight manner at the upper end of the main rod 11. Further, the vertical tube 12 is suspended from the center portion of the inner surface of the disk-shaped top wall portion 13a of the cover cylinder 13, and the peripheral wall portion 13b is suspended from the peripheral edge portion of the top wall portion 13a, thereby constituting the cover cylinder 13. A recess 13c for hanging a finger is recessed from the central portion of the top wall portion 13a to the rear end portion. Further, reinforcing ribs 14 are suspended between the peripheral wall portion 13b and the vertical tube 12 at right and left and rear portions.
又，在縱筒12的上部內使基端開口，同時，其具有使前端成為吐出口a之吐出噴嘴15，且自縱筒12通過吐出噴嘴15，其達到吐出口a而在內部形成流路p。吐出噴嘴15其縱剖面形狀為形成橫長四角形狀。而貫通周壁部13b朝向前方突設使前端部成為吐出口a，又在周壁部13b內之側壁部份藉設置推拔部16而使流路p擴開。又，流路p係朝向前端傾斜上升。又，吐出口a在前端部下部成為設有切缺開口部17之形態。又自前端底壁部份至兩側壁下部穿設有切缺開口部17，因此兩側壁下部各別被切缺而成為圓弧狀。Further, the base end is opened in the upper portion of the vertical tube 12, and the discharge nozzle 15 having the tip end as the discharge port a is provided, and the discharge tube 15 is passed through the discharge nozzle 15 from the vertical tube 12, and the discharge port a is formed to form a flow path therein. p. The discharge nozzle 15 has a longitudinal cross-sectional shape to form a horizontally long square shape. The through-wall portion 13b protrudes forward so that the front end portion serves as the discharge port a, and the push-side portion 16 is provided in the side wall portion of the peripheral wall portion 13b to expand the flow path p. Further, the flow path p is inclined upward toward the front end. Further, the discharge port a is formed in the lower portion of the front end portion so as to have the cutout opening portion 17. Further, the cutout opening portion 17 is formed from the bottom wall portion of the front end to the lower portion of the two side walls. Therefore, the lower portions of the two side walls are each cut into an arc shape.
在吐出噴嘴15下方之縱筒12前部設有手指接觸面f。手指接觸面f係在吐出口a下方之縱筒12前面設有寬幅度的板狀部18而使其前面構成手指接觸面f，而呈中央朝後方突出形成彎曲面形態。又，當以單手實施泡沫吐出操作時藉由使手掌抵接朝上之食指的側面，則當在壓下吐出噴頭1時手指則不會發生有夾在縱筒12與安裝蓋10之間等的缺點。A finger contact surface f is provided at the front portion of the vertical cylinder 12 below the discharge nozzle 15. The finger contact surface f is provided with a wide plate-like portion 18 on the front surface of the vertical tube 12 below the discharge port a, and the front surface thereof constitutes the finger contact surface f, and the center portion protrudes rearward to form a curved surface. Further, when the palm spouting operation is performed with one hand, the palm is abutted against the side of the index finger facing upward, and the finger does not occur between the vertical tube 12 and the mounting cover 10 when the ejection head 1 is pressed down. The shortcomings of etc.
又採用上述吐出噴頭1之吐泡沫用泵A係，藉使吐出噴頭1抗拒上方加壓力而壓下之內部機構的作用而從主桿11吐出泡沫至縱筒12內，再通過吐出噴嘴15自吐出口a被吐出。在吐出泡沫時，即使手掌位於吐出口a之前下方並藉同一隻手的拇指而按壓吐出噴頭1時，則泡沫可確實地吐出至手掌上。Further, the discharge foam pump A of the discharge head 1 is used to discharge the foam from the main rod 11 into the vertical tube 12 by the action of the internal mechanism that the discharge head 1 resists the upper pressing force, and then passes through the discharge nozzle 15 The spit outlet a is spit out. When the foam is discharged, even if the palm is placed below the discharge port a and the spout head 1 is pressed by the thumb of the same hand, the foam can be reliably discharged to the palm.
圖6至圖8表示吐出噴嘴15之流路p在水平時之例子，其設有自吐出噴嘴15之前端面上下方向中間部至蓋筒周壁部13b為止的切缺開口部17。由於其他構成係和圖1之例相同，因此，其被附加同一符號而省略其說明。6 to 8 show an example in which the flow path p of the discharge nozzle 15 is horizontal, and a cutout opening portion 17 from the intermediate portion in the vertical direction of the end surface of the discharge nozzle 15 to the peripheral wall portion 13b of the cover cylinder is provided. Since the other components are the same as those of the example of FIG. 1, the same reference numerals are attached and the description thereof is omitted.
又圖9表示在吐出噴頭1上面設有防滑部20之例，由於其他構成和圖6之例相同，因此，其被附加同一符號而省略其說明。Further, Fig. 9 shows an example in which the anti-slip portion 20 is provided on the discharge head 1, and the other configuration is the same as that of Fig. 6, and the same reference numerals are attached thereto, and the description thereof is omitted.
圖10表示取代推拔部16而藉由段部21使流路p擴大直徑之例，而其他之構成則和圖6相同。FIG. 10 shows an example in which the flow path p is enlarged in diameter by the segment portion 21 instead of the push-out portion 16, and the other configuration is the same as that in FIG. 6.
