Abstract

<P>PROBLEM TO BE SOLVED: To prevent air in a container of a pump type product expanded due to a variation of surrounding temperature from pressurizing content in it and further prevent the pressurized content from being leaked out in liquid form of a discharging port through its original discharging passage while releasing an upper valve and a lower valve. <P>SOLUTION: An abutting portion between a piston 3 and a member 10 for setting an upward moving position of the piston has an opening part 10b in such a way that, under a standstill mode where the piston 3 and the member 10 are abutted to each other, air expanded in a container can escape into the external space through the abutted portion and an air flowing-in or flowing-out passage 11. Since the opening part and its inlet side passage region are set to such a size as to enable also the content to pass through them, it is possible to restrict a degree of the expanded air in the container for pressurizing the content to a low level, and the upper valve and the lower valve are not released to open even if a closed state of the lower valve (an upstream side valve) is not forcedly maintained by arranging a resilient member at the lower valve. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、内容物放出用ポンプ機構において容器内部の減圧を防止するための空気用通路に関し、特に操作部が操作されていない静止モードの容器が倒れたときにも容器内容物が外部空間にこぼれないようにするための(当該空気用通路の)いわば弁作用部分に、容器内容物が通過可能な大きさからなる空気流出用通路域を形成したものである。   The present invention relates to an air passage for preventing decompression of the inside of a container in a pump for discharging contents, and in particular, when the container in a stationary mode in which the operation unit is not operated falls down, the container contents remain in the external space. An air outflow passage area having a size that allows the contents of the container to pass therethrough is formed in the valve action portion (of the air passage) so as not to spill.

この空気流出用通路域の形成により、ポンプ容器が置かれている環境の温度が高い状況で静止モードの容器内部の空気が膨張してもそれは空気用通路から外部空間へ積極的に流出することになる。   By forming this air outflow passage area, even if the air inside the stationary mode container expands in a situation where the temperature of the environment where the pump container is placed is high, it will actively flow out from the air passage to the external space. become.

なお、操作部の操作に基づく作動モードでは空気用通路の弁作用部分が開状態になって当該空気用通路から外気が流入することにより、容器内部の減圧を防止している。   In the operation mode based on the operation of the operation unit, the valve action portion of the air passage is opened and the outside air flows from the air passage, thereby preventing the decompression of the inside of the container.

一般に、弁作用部分が弾性や自重により閉塞するポンプ式製品は、それが置かれている環境の温度が高くなると(例えば使用後の風呂場や夏季の洗面室などに置かれている場合)、容器内部の空気が膨張して内容物を加圧する。そして、このときの圧力により内容物放出通路の途中に配置されている下方弁,上方弁が開状態となる。   In general, a pump-type product in which the valve action part is blocked by elasticity or its own weight, when the temperature of the environment in which it is placed becomes high (for example, when it is placed in a bathroom after use or in a bathroom in summer) The air inside the container expands and pressurizes the contents. And the lower valve and the upper valve which are arrange | positioned in the middle of the content discharge passage by the pressure at this time will be in an open state.

そうすると、本来は閉状態の下方弁,上方弁の作用により容器内部に閉じ込められているはずの内容物がその本来の放出通路を経て放出口まで移動し、当該放出口から液垂れして「つらら」状の形で固まってしまうことが多く、使い勝手も悪くなってしまう。   Then, the contents that should have been confined inside the container by the action of the lower valve and the upper valve in the closed state move to the discharge port through the original discharge passage, dripping from the discharge port, It often hardens in the form of a "", and the usability becomes worse.

本発明は、内容物放出用ポンプ機構の放出口におけるこのような「つらら」現象を確実に解消したいという要請に対し、静止モードにおける空気用通路の作用についてのいわば発想の転換に基づく工夫により応えるものである。   The present invention responds to the request to reliably eliminate such “icicle” phenomenon at the discharge port of the content discharge pump mechanism by means of a change in the concept of the action of the air passage in the stationary mode. Is.

静止モードの容器内で膨張した空気を容器内減圧防止用の空気用通路から外部空間に排出することにより、上記液垂れを防止しようとする内容物放出用ポンプ機構は、すでに提案されている(特許文献1参照)。   There has already been proposed a content discharge pump mechanism for preventing the liquid dripping by discharging the air expanded in the stationary mode container from the air passage for preventing decompression in the container to the external space ( Patent Document 1).

この内容物放出用ポンプ機構の場合、押下げヘッド(=操作部)と一体になって連動するステム(=ピストン)が案内されるシリンダに設けた外気吸入孔(=減圧防止用孔部)から続く周知の空気用通路の弁作用部分に、容器内部の膨張空気を外部空間に逃がすための空気流出用通路域を確保している。   In the case of this content discharge pump mechanism, from an outside air suction hole (= pressure-reducing prevention hole) provided in a cylinder guided by a stem (= piston) which is integrated with the push-down head (= operation part). An air outflow passage area for releasing the expanded air inside the container to the external space is secured in the valve action portion of the well-known air passage.

そしてこの空気流出用通路域は「通水不能でかつ通気性を有する微小通路」である。すなわち静止モードにおいて、容器内部の膨張空気は外部空間に逃げるものの、容器が倒れた場合などでも容器内容物は外部空間に漏洩しない程度の大きさからなる「微小通路」である。
特開平10−181761号公報
The passage area for air outflow is “a minute passage that is impermeable to water and has air permeability”. That is, in the stationary mode, the expanded air inside the container escapes to the external space, but the container contents are “micro passages” having such a size that the container contents do not leak to the external space even when the container falls down.
Japanese Patent Laid-Open No. 10-181761

本件出願人は、ポンプ式製品の静止モードにおける放出口の「つらら」発生と、容器内部減圧防止用の空気用通路の弁作用部分における空気流出用通路域での空気通過面の大きさとの関係を考察して検証したところ、内容液の特性しだいでは、上述の「微小通路」の大きさでは容器内部の膨張空気を外部空間に十分に流出させることはできず、内容物通路域の放出口における「つらら」発生を防止するのが難しいことを確認した。   The present applicant relates to the relationship between the occurrence of icicles in the discharge port in the stationary mode of the pump-type product and the size of the air passage surface in the air outflow passage area in the valve action portion of the air passage for preventing decompression inside the container. As a result of examining the characteristics of the content liquid, the size of the above-mentioned `` micro-channel '' does not allow the expanded air inside the container to sufficiently flow out to the external space. It was confirmed that it was difficult to prevent the occurrence of "icicles".

そして、この「つらら」状態が発生しやすい内容物を入れたポンプ式製品は通常、浴室や洗面台などのように静止モードの容器が倒れて内容物がいくらか漏洩しても簡単に清掃できるような環境で使われることが多い。   And pump-type products that contain contents that are prone to this “icicle” condition are usually easy to clean even if the containers in a stationary mode, such as bathrooms or washstands, collapse and some contents leak. Often used in difficult environments.

本発明では、ポンプ式製品におけるこれらの膨張空気流出作用や使用環境に着目して、容器内減圧防止用の空気用通路の弁作用部分での空気流出用通路域の大きさを「容器内容物も通過可能な大きさ」にするといったきわめて有意な発想の転換を行うことにより、静止モードにおける容器内部の膨張空気を空気用通路から外部空間へと積極的に流出させて、内容物放出口での「つらら」生成を極力なくすことを目的とする。   In the present invention, paying attention to the expansion air outflow action and usage environment in the pump type product, the size of the air outflow passage area in the valve action portion of the air passage for preventing decompression in the container is defined as “container contents”. By making a very significant change in concept such as `` the size that can pass through '', the expansion air inside the container in the stationary mode is actively discharged from the air passage to the outside space, and the contents discharge port The purpose is to minimize the generation of "icicles".

本発明は、以上の課題を次の内容物放出用ポンプ機構を用いて解決する。
(1)容器内容物を外部空間に放出させるための操作部(例えば後述の操作ボタン1)と連動するとともに、弾性力(例えば後述のコイルスプリング4の弾性力)により静止モード位置の方に付勢されて、内側空間には内容物通路域および下流弁(例えば後述の上方弁2)を有し、外周面には静止モード位置に保持されるための被保持部分(例えば後述の段部3b)を形成した筒状のピストン(例えば後述のピストン3)と、
前記操作部の作動モード設定操作にともなう前記ピストンの往復動作を案内するとともに、前記内容物通路域に通じる内容物収納空間および容器内部に対する減圧防止用孔部(例えば後述の減圧防止用孔部5a)を設けたシリンダ(例えば後述のシリンダ5)と、
前記減圧防止用孔部を外部空間に連通させるための空気用通路(例えば後述の空気流入出用通路11)を前記ピストンの外周面との間に形成するとともに、前記作動モード設定操作に対応した当該ピストンの前記往復動作の途中では前記被保持部分から離間して、また静止モード位置では前記被保持部分に当接する態様の保持部分(例えば後述の間歇状段部10a,受け部分9e)を設けた、筒状のピストン上動位置設定部材(例えば後述のシール用・通路設定用部材10,内筒状部9d)とを備え、
前記ピストンの静止モード位置において当接する前記被保持部分および前記保持部分の少なくとも一方に、この当接状態で容器内部の膨張空気を当該減圧防止用孔部から前記空気用通路を経て外部空間に逃がすための空気流出用通路域(例えば後述の開口部10b,9f)を、容器内容物も通過可能な大きさの態様で形成する
(2)上記(1)において、
前記空気流出用通路域は、
その中の空気流れ方向に対する通過面が少なくとも、前記ピストンの外周面と前記ピストン上動位置設定部材の内周面とのスペース間隔(例えば後述の距離s)で特定される正方形よりも大きく設定されたものとする。
The present invention solves the above-described problems by using the following contents discharge pump mechanism.
(1) In conjunction with an operation portion (for example, an operation button 1 described later) for releasing the contents of the container to the external space, it is attached toward the stationary mode position by an elastic force (for example, an elastic force of a coil spring 4 described later). The inner space has a content passage area and a downstream valve (for example, an upper valve 2 described later), and a held portion (for example, a stepped portion 3b described later) is held on the outer peripheral surface in a stationary mode position. A cylindrical piston (for example, a piston 3 described later),
The reciprocating operation of the piston in accordance with the operation mode setting operation of the operation unit is guided, and a decompression prevention hole portion (for example, a later-described decompression prevention hole portion 5a described later) with respect to the content storage space and the inside of the container which leads to the content passage area ) Provided with a cylinder (for example, a cylinder 5 described later),
An air passage (for example, an air inflow / outflow passage 11 described later) for communicating the decompression prevention hole portion with an external space is formed between the outer peripheral surface of the piston and corresponds to the operation mode setting operation. In the middle of the reciprocating motion of the piston, there are provided holding portions (for example, intermittent stepped portion 10a and receiving portion 9e described later) that are separated from the held portion and abut against the held portion in the stationary mode position. In addition, a cylindrical piston upward movement position setting member (for example, a seal / passage setting member 10, which will be described later, an inner cylindrical portion 9d),
At least one of the held portion and the holding portion that are in contact with each other in the stationary mode position of the piston causes the expanded air inside the container to escape from the decompression prevention hole portion to the external space through the air passage in this contact state. Forming an air outflow passage area (for example, openings 10b and 9f to be described later) in such a size that the contents of the container can also pass (2) In the above (1),
The air outflow passage area is
The passage surface in the air flow direction is set larger than at least a square specified by a space interval (for example, a distance s described later) between the outer peripheral surface of the piston and the inner peripheral surface of the piston upward movement position setting member. Shall be.

本発明は、このような構成からなる内容物放出用ポンプ機構および、これを備えたポンプ式製品を対象としている。   The present invention is directed to a content discharge pump mechanism having such a configuration and a pump-type product including the same.

本発明は、このように、内容物放出口の「つらら」が生成されやすいポンプ式製品の使用環境(浴室,洗面所など)での漏洩内容物による汚れといった問題がそれほど深刻でないことに鑑み、もともとは容器内減圧防止用である空気(流入用)通路の弁作用部分に形成される空気流出用通路域を「容器内容物も通過可能な大きさ」に設定し、この空気流入用通路を大きな「空気流出用通路」としても積極的に用いるものである。   In view of the fact that the problem of contamination due to leaked contents in the usage environment (bathroom, toilet, etc.) of the pump-type product in which the “icicle” of the content discharge port is easily generated is not so serious, Originally, the air outflow passage area formed in the valve action part of the air (inflow) passage, which is used to prevent decompression in the container, is set to “size that allows the contents of the container to pass through”. It is also actively used as a large “air outflow passage”.

さらには、この空気流出用通路域の空気通過面を「空気流入出用通路」のいわば大きさともいえる「ピストンの外周面とピストン上動位置設定部材の内周面とのスペース間隔」で特定される正方形よりも大きくなる、ように設定している。   Furthermore, the air passage surface of this air outflow passage area is specified by the “space interval between the outer peripheral surface of the piston and the inner peripheral surface of the piston upward movement position setting member”, which is the size of the “air inflow / outflow passage”. It is set to be larger than the square to be.

そのため、静止モードにおける容器内部の膨張空気はこの大きな空気流入出用通路(空気流出用通路域)から外部空間へと積極的に流出していくので、当該膨張空気が内容物を押圧して下流側の方に移動させようとする放出作用がきわめて小さくなり、内容物放出口での「つらら」の発生を抑えることができる。   Therefore, since the expanded air inside the container in the stationary mode actively flows out from the large air inflow / outflow passage (air outflow passage area) to the external space, the expanded air presses the contents downstream. The discharge action to be moved to the side becomes extremely small, and the occurrence of “icicle” at the content discharge port can be suppressed.

また、このように膨張空気の内容物に対する放出方向への押圧作用が小さいので、ポンプ機構の下方弁(上流弁:図示省略)として上記特許文献で開示されている弾性バネ片付きの弁を用いなくても、当該下方弁が膨張空気の作用で開くこともない。   In addition, since the pressing action in the discharge direction against the contents of the expanded air is small as described above, the valve with the elastic spring piece disclosed in the above-mentioned patent document is not used as the lower valve (upstream valve: not shown) of the pump mechanism. However, the lower valve is not opened by the action of the expanded air.

すなわち、下方弁として例えばボール弁を用いるだけでも上記「つらら」の発生を防止可能であり、ポンプ機構の組立作業の簡単化および当該機構のコスト低減化を図ることができる。   That is, the occurrence of the “icicle” can be prevented only by using, for example, a ball valve as the lower valve, and the assembly work of the pump mechanism can be simplified and the cost of the mechanism can be reduced.

(12) The height h and the straight line width w of the rectangular opening 10b, which is a component of the saddle-like stepped portion 10a, are set to values larger than the distance s of the air inflow / outflow passage 11, respectively.
That is.

これにより、静止モードにおける容器内部の膨張した空気の外部空間への流出動作が確実に行われることになる。   Thereby, the outflow operation to the external space of the expanded air inside the container in the stationary mode is reliably performed.

これらの距離s,高さhおよび直線幅wはそれぞれ例えば、

Stops in contact.

そしてシール用・通路設定用部材10はその上側スカート部10cの上端部分がカラー部材9の下端部分に当接した上動位置に保持されている。   The sealing / passage setting member 10 is held in the upward movement position in which the upper end portion of the upper skirt portion 10 c is in contact with the lower end portion of the collar member 9.

このとき減圧防止用孔部5aは、ポンプ式製品の出荷・販売段階よりも上方の位置に移動したシール用・通路設定用部材10の上側スカート部10cおよび下側スカート部10dによってシールされることはない。   At this time, the decompression preventing hole 5a is sealed by the upper skirt portion 10c and the lower skirt portion 10d of the sealing / passage setting member 10 moved to a position higher than the stage of shipment and sale of the pump type product. There is no.

そのため、容器内部で膨張した空気は減圧防止用孔部5aおよび空気流入出用通路11(シール用・通路設定用部材10の開口部10b)を通って外部空間に流出する。   Therefore, the air expanded inside the container flows out to the external space through the decompression preventing hole 5a and the air inflow / outflow passage 11 (the opening 10b of the seal / passage setting member 10).

また、上方弁2および下方弁(図示省略)はともに閉じ、これらの弁間のピストン3およびシリンダ5の内部空間域には内容物が入っている。   The upper valve 2 and the lower valve (not shown) are both closed, and the contents are contained in the internal space of the piston 3 and the cylinder 5 between these valves.

それは、前回の放出操作にともなうピストン3(操作ボタン1)の静止モード位置への復帰動作時に上記内部空間域の容積が増加してそこでの圧力が容器内部よりも減少し、その結果下方弁(図示省略)が開いて容器内部の内容物が当該内部空間域に流入するためである。   This is because when the piston 3 (operation button 1) is returned to the stationary mode position due to the previous release operation, the volume of the internal space region increases and the pressure in the space decreases below the inside of the container. This is because the contents inside the container flow into the internal space area.

この内容物流入により容器内部の(内容物が存在していない空間域の)空気圧が減じることになるが、その減少分に見合った量の外気が空気流入出用通路11および減圧防止用孔部5aを通って容器内部に流入する。   The inflow of the contents reduces the air pressure inside the container (in the space where the contents do not exist). The amount of outside air commensurate with the reduced amount is supplied to the air inflow / outflow passage 11 and the decompression prevention hole. It flows into the container through 5a.

操作ボタン1がコイルスプリング4の弾性力に抗して押し下げられた状態の作動モードでは、上記弁間のピストン3およびシリンダ5の内部空間域の容積が小さくなるため、そこの内容物圧力が大きくなって上方弁2が開いて当該内部空間域の内容物が放出用通路を経て外部空間に放出される。   In the operation mode in which the operation button 1 is pushed down against the elastic force of the coil spring 4, the volume of the internal space area of the piston 3 and the cylinder 5 between the valves is reduced, so that the content pressure there is large. Thus, the upper valve 2 is opened, and the contents in the internal space area are discharged to the external space through the discharge passage.

このとき下方弁(上流弁)は周知のごとく勿論閉じている。また、シール用・通路設定用部材10の上側スカート部10cおよび下側スカート部10dは、それぞれの端部が自身の外方向への弾性付勢力によってシリンダ5の内周面に密接しているので、図示の静止モード位置に保持されたままとなる。   At this time, the lower valve (upstream valve) is of course closed as is well known. Further, since the upper skirt portion 10c and the lower skirt portion 10d of the sealing / passage setting member 10 are in close contact with the inner peripheral surface of the cylinder 5 by the elastic biasing force in the outward direction thereof. It remains held in the illustrated still mode position.

そして利用者が操作ボタン1の押圧操作を止めると、当該操作ボタンおよびピストン3はコイルスプリング4の弾性作用により上動して図示の静止モード位置となる。この際に下方弁(上流弁)が開いて上記内部空間域に容器内容物が流入するのは上述のとおりである。   When the user stops the pressing operation of the operation button 1, the operation button and the piston 3 are moved up by the elastic action of the coil spring 4 to the illustrated stationary mode position. At this time, the lower valve (upstream valve) is opened and the contents of the container flow into the internal space as described above.

なお周知のことであるが、ポンプ式製品の出荷・販売段階における操作ボタン1は、作動モード位置よりも押下げられる形でその内周面とカラー部材9の外側螺子部分とが螺合した状態に設定される。   As is well known, the operation button 1 in the shipment / sales stage of the pump-type product is in a state where its inner peripheral surface and the outer screw portion of the collar member 9 are screwed together so as to be pushed down from the operation mode position. Set to

そしてこの螺合状態におけるシール用・通路設定用部材10は、その上端部分が操作ボタン1の天井面に押圧されて図示の位置よりも下方に移動しており、上側スカート部10cおよび下側スカート部10dでシリンダ5の減圧防止用孔部5aをシールした状態になっている。このシール作用により、減圧防止用孔部5aと空気流入出用通路11との間が遮断される。   The upper end portion of the sealing / passage setting member 10 in the screwed state is pressed by the ceiling surface of the operation button 1 and is moved downward from the position shown in the drawing. The upper skirt portion 10c and the lower skirt The portion 10d seals the decompression prevention hole 5a of the cylinder 5. By this sealing action, the space between the decompression preventing hole 5a and the air inflow / outflow passage 11 is blocked.

(21)図1のシール用・通路設定用部材10を省略して、
