Description

本発明は、エアレスポンプ機構の容器本体内周面に密接して容器本体の液状内容物に対するシール作用を呈し、かつ、内容物吐出動作にともなう容器本体の内容物収容空間域の圧力低下に応じて外気圧の作用により移動する、内容物収容空間域画定用の可動シール部材などに関する。なお、本明細書で用いる「液状内容物」はクリーム状やゾル状などの各種内容物を含む概念である。   The present invention is in close contact with the inner peripheral surface of the container body of the airless pump mechanism and exhibits a sealing action for the liquid contents of the container body, and responds to the pressure drop in the contents storage space area of the container body accompanying the contents discharge operation. The present invention relates to a movable seal member for demarcating a content accommodation space, which is moved by the action of external atmospheric pressure. The “liquid content” used in the present specification is a concept including various contents such as cream and sol.

特にエアレスポンプ機構の容器本体内周面とのシール作用部分を、反発弾性部材で形成した、すなわち変形を受けても瞬時に回復する性状のゴムまたは熱可塑性エラストマーからなる弾性部材で形成した、内容物収容空間域画定用の可動シール部材に関する。   In particular, the sealing action part with the inner peripheral surface of the container body of the airless pump mechanism is formed of a repulsive elastic member, that is, formed of an elastic member made of rubber or thermoplastic elastomer with the property of recovering instantaneously even when subjected to deformation. The present invention relates to a movable seal member for defining an object accommodation space area.

このような反発弾性部材からなるシール作用部分を備えた可動シール部材で容器本体の内容物収容空間域を画定することにより、低粘度の液状内容物に対しても十分なシール性を確保でき、また、当該可動シール部材が容器本体に組み込まれた状態で内容物未充填の容器本体外面へのフィルムシュリンク加工を行った後も、当該可動シール部材と容器本体内周面との間のシール性が劣化するのを防止できる。   By demarcating the contents-accommodating space area of the container body with a movable sealing member having a sealing action portion made of such a repulsive elastic member, sufficient sealing performance can be secured even for low-viscosity liquid contents, In addition, the sealing property between the movable seal member and the inner peripheral surface of the container main body after the film shrink process is performed on the outer surface of the container main body that is not filled with the contents in the state where the movable seal member is incorporated in the container main body. Can be prevented from deteriorating.

これは、ゴムまたは熱可塑性エラストマーからなる比較的軟質の反発弾性部材と容器本体内周面との間にもともと強い密接状態が形成され、また、反発弾性部材自体がフィルムシュリンク加工時の熱処理による収縮などの影響をほとんど受けないからである。   This is because a strong close state is formed between the relatively soft rebound elastic member made of rubber or thermoplastic elastomer and the inner peripheral surface of the container body, and the rebound elastic member itself contracts by heat treatment during film shrink processing. It is because it is hardly influenced by such.

本発明のエアレスポンプ機構における可動シール部材の有効的な使用対象内容物は、粘度が低くていわばさらっとした液状内容物、例えば薬剤,石けん,消毒剤,化粧品,洗剤,染毛剤,シャンプー,リンス,殺虫剤などである。なお、本発明の可動シール部材が高粘度の液状内容物にも適用できることは勿論である。   The effective use target contents of the movable seal member in the airless pump mechanism of the present invention are low-viscosity liquid contents such as drugs, soaps, disinfectants, cosmetics, detergents, hair dyes, shampoos, etc. Rinse, insecticide, etc. Needless to say, the movable seal member of the present invention can also be applied to high-viscosity liquid contents.

エアレスポンプ機構、すなわち容器本体の内容物収容空間域を画定する可動シール部材(容器本体内周面に対する底部側の可動シール部材)が、当該ポンプ機構の内容物吐出動作にともなう容器本体内容物の減少分(圧力低下分)に応じて外気圧の作用により上方向に移動するポンプ機構自体は、周知であり、例えば下記特許文献1,2で開示される。   The airless pump mechanism, that is, the movable seal member (movable seal member on the bottom side with respect to the inner peripheral surface of the container main body) that defines the content storage space area of the container main body The pump mechanism itself that moves upward by the action of the external air pressure in accordance with the decrease (pressure decrease) is well known, and is disclosed, for example, in Patent Documents 1 and 2 below.

ここで、容器本体の内容物収容空間域の底面を構成する可動シール部材はポリエチレンなどの比較的硬いプラスチック素材が用いられている。   Here, a relatively hard plastic material such as polyethylene is used for the movable seal member that constitutes the bottom surface of the content storage space of the container body.

特開2006−44170号公報JP 2006-44170 A 特開平10−59405号公報JP-A-10-59405

このようなエアレスポンプ機構におけるプラスチック製の可動シール部材は、もっぱら高粘度の液状内容物を対象としており、低粘度の液状内容物に対するシール性の点では改善の余地を残したものであった。   The plastic movable seal member in such an airless pump mechanism is exclusively intended for the high-viscosity liquid content, and has left room for improvement in terms of sealability with respect to the low-viscosity liquid content.

また、容器本体にプラスチック製の可動シール部材を組み込んだ状態で内容物未充填の容器本体外周面などにフィルムシュリンク加工を行うと、そこでの必須処理であるフィルム収縮用熱処理のために当該可動シール部材まで収縮してしまい、容器本体内周面とのシール性自体が損なわれやすいという点でも改善の余地を残していた。   In addition, when film shrink processing is performed on the outer peripheral surface of the container body that is not filled with the contents while the plastic movable seal member is incorporated in the container body, the movable seal is used for heat treatment for film shrinkage, which is an essential process therefor. There is still room for improvement in that it contracts to the member and the sealing performance itself with the inner peripheral surface of the container body tends to be impaired.

そこで、本発明では、エアレスポンプ機構の内容物収容空間域を画定する可動シール部材のシール作用部分を、さらには当該可動シール部材の全体を、ゴムまたは熱可塑性エラストマーからなる比較的軟質の反発弾性部材で形成して、低粘度の液状内容物の使用時にも容器本体内周面との間の十分なシール性が担保されることを目的とする。   Therefore, in the present invention, a relatively soft rebound resilience made of rubber or a thermoplastic elastomer is used for the sealing action portion of the movable seal member that delimits the content accommodation space area of the airless pump mechanism, and further for the entire movable seal member. It is an object of the present invention to provide a sufficient sealing property between the inner peripheral surface of the container body even when the low-viscosity liquid content is used.

かつ、この反発弾性部材からなる可動シール部材が容器本体に組み込まれた状態で内容物未充填の容器本体外面へのフィルムシュリンク加工(熱処理など)を行った場合にも、当該可動シール部材はほとんど収縮せずに、当該可動シール部材と容器本体内周面との間の良好なシール性が維持されることを目的とする。   Even when film shrink processing (heat treatment, etc.) is performed on the outer surface of the container body which is not filled with the movable seal member made of the resilience elastic member incorporated in the container body, the movable seal member is hardly used. An object is to maintain a good sealing property between the movable seal member and the inner peripheral surface of the container body without contracting.

本発明は、以上の課題を次のようにして解決する。
(1)エアレスポンプ機構の容器本体(例えば後述の容器本体1)内周面に密接してシール作用を呈し、かつ、内容物吐出動作にともなう容器本体の内容物収容空間域の圧力低下に応じて外空圧の作用により移動する、内容物収容空間域画定用の可動シール部材(例えば後述の可動底部材2,3)を、
少なくとも前記容器本体内周面とのシール作用部分(例えば後述の逆スカート部2a,スカート部2b,逆スカート部3b,スカート部3c)が、変形を受けても瞬時に回復する性状のゴムまたは熱可塑性エラストマーからなる反発弾性部材で形成され、
容器本体に組み込まれた状態で当該容器本体の外面部分にフィルム(例えば後述のフィルム5)を被せて加熱するシュリンク加工後も、前記容器本体内周面とのシール性が損なわれない、
形のものに設定する。
(2)上記(1)において、
前記シール作用部分を含む形状の全体(例えば後述の可動底部材2)を前記反発弾性部材で形成する。
The present invention solves the above problems as follows.
(1) A container body (for example, a container body 1 to be described later) of the airless pump mechanism exhibits a sealing action in close contact with the inner peripheral surface, and responds to a pressure drop in the content storage space area of the container body due to the content discharge operation. A movable seal member (for example, movable bottom members 2 and 3 to be described later) that moves by the action of the outside air pressure for demarcating the content storage space area,
A rubber or heat having a property that at least a sealing action portion (for example, a reverse skirt portion 2a, a skirt portion 2b, a reverse skirt portion 3b, and a skirt portion 3c, which will be described later) is instantaneously recovered even when subjected to deformation Formed of a rebound elastic member made of a plastic elastomer,
Even after shrink processing in which the outer surface portion of the container body is covered with a film (for example, film 5 described later) and heated while being incorporated in the container body, the sealing performance with the inner peripheral surface of the container body is not impaired,
Set to a shape.
(2) In (1) above,
The entire shape including the sealing portion (for example, a movable bottom member 2 described later) is formed by the repulsive elastic member.

本発明は、以上の構成からなるエアレスポンプ機構の内容物収容空間域画定用の可動シール部材および当該可動シール部材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 movable seal member for defining the contents-accommodating space area of the airless pump mechanism configured as described above and a pump-type product including the movable seal member.

本発明はこのように、エアレスポンプ機構の内容物収容空間域を画定する可動シール部材のシール作用部分を、さらには当該可動シール部材の全体を、ゴムまたは熱可塑性エラストマーからなる比較的軟質の反発弾性部材で形成しているため、低粘度および高粘度のいずれの液状内容物に対しても、容器本体内周面との間の十分なシール性を確保することができる。   In this way, the present invention provides a relatively soft repulsion made of rubber or thermoplastic elastomer for the sealing action portion of the movable seal member that defines the content accommodating space of the airless pump mechanism, and further for the entire movable seal member. Since it is formed of an elastic member, a sufficient sealing property between the inner peripheral surface of the container body can be ensured for any liquid content having a low viscosity and a high viscosity.

また、この反発弾性部材からなる可動シール部材が容器本体に組み込まれた状態で内容物未充填の容器本体外面へのフィルムシュリンク加工(熱処理など)を行った場合にも、当該可動シール部材はほとんど収縮せずに、当該可動シール部材と容器本体内周面との間の良好なシール性を維持することができる。この非収縮性効果は可動シール部材の全体を反発弾性部材で形成した場合に顕著となる。   Further, even when film shrink processing (such as heat treatment) is performed on the outer surface of the container body which is not filled with the movable seal member made of the repulsive elastic member incorporated in the container body, the movable seal member is hardly used. It is possible to maintain a good sealing performance between the movable seal member and the inner peripheral surface of the container body without contracting. This non-shrinkage effect becomes prominent when the entire movable seal member is formed of a repulsive elastic member.

これらの効果を奏するのは、ゴムまたは熱可塑性エラストマーからなる比較的軟質の反発弾性部材と容器本体内周面との間にもともと強い密接状態が形成され、また、反発弾性部材自体がフィルムシュリンク加工時の熱処理による収縮などの影響をほとんど受けないからである。   These effects are achieved by the fact that a strong close state is formed between the relatively soft rebound elastic member made of rubber or thermoplastic elastomer and the inner peripheral surface of the container body, and the rebound elastic member itself is subjected to film shrink processing. This is because it is hardly affected by shrinkage due to heat treatment.

また、通常、可動シール部材が密接する容器本体内周面にシリコーン潤滑剤などを塗布して当該可動シール部材の移動の円滑化を図っているところ、そのシール作用部分に上記反発弾性部材を用いているため、シリコーン潤滑剤の塗布層を薄くすることができる。   Further, normally, a silicone lubricant or the like is applied to the inner peripheral surface of the container main body, which is in close contact with the movable seal member, so as to facilitate the movement of the movable seal member. Therefore, the coating layer of the silicone lubricant can be made thin.

なお、可動底部材2および外側ゴム部材3aとして、ゴム材の代わりに、各種の熱可塑性エラストマー、例えばオレフィン系熱可塑性エラストマーやスチレン系熱可塑性エラストマーを用いてもよい。   In addition, as the movable bottom member 2 and the outer rubber member 3a, various thermoplastic elastomers such as an olefin-based thermoplastic elastomer and a styrene-based thermoplastic elastomer may be used instead of the rubber material.

The annular seal member 8 is made of rubber or plastic.

図示したエアレスポンプ機構の中で本発明の実施形態に特有な構成要素は可動底部材2,3の材質およびフィルム5のみといえる。エアレスポンプ機構自体は汎用のものであり、ハウジング7の内部から操作ボタン9にいたるポンプ機構およびそこでの吐出弁および吸込弁の関連動作も周知である。   In the illustrated airless pump mechanism, only the material of the movable bottom members 2 and 3 and the film 5 can be said to be unique to the embodiment of the present invention. The airless pump mechanism itself is a general-purpose one, and the pump mechanism from the inside of the housing 7 to the operation button 9 and related operations of the discharge valve and the suction valve there are also well known.

エアレスポンプ機構の場合、吐出動作によりハウジング内部空間域Bの液状内容物が孔部9bから外部に吐出されると、その吐出相当量の液状内容物が容器本体内部空間域Aからハウジング内部空間域Bに流入する。   In the case of the airless pump mechanism, when the liquid content in the housing internal space area B is discharged to the outside through the hole 9b by the discharge operation, the liquid content corresponding to the discharge is discharged from the container body internal space area A to the housing internal space area. Flows into B.

この液状内容物の流入にともなって容器本体内部空間域Aの圧力が大気圧よりも小さくなるので、可動底部材2,3が大気圧で押される形で図示上方向に移動する。   As the liquid content flows in, the pressure in the inner space A of the container main body becomes smaller than the atmospheric pressure, so that the movable bottom members 2 and 3 are moved upward in the figure while being pushed at the atmospheric pressure.

本発明は、エアレスポンプ機構の内容物吐出動作に際して必然的に図示上方向に移動する可動底部材2,3に関して、
(11)容器本体1の内周面との間のシール性が、低粘度の液状内容物に対しても十分に担保され、
(12)かつ、当該可動底部材を容器本体1に組み込んだ状態で内容物未充填のその外周面などに(熱処理をともなう)フィルムシュリンク包装をおこなうときの、当該熱処理による当該可動底部材の収縮などの影響を極力小さくして、当該可動底部材の容器本体内周面に対するシール性能の劣化防止を図れる、
ようにしたものである。
The present invention relates to the movable bottom members 2 and 3 that inevitably move in the upward direction in the figure when the contents are discharged by the airless pump mechanism.
(11) The sealing property between the inner peripheral surface of the container body 1 is sufficiently secured even for a low-viscosity liquid content,
(12) The shrinkage of the movable bottom member due to the heat treatment when film shrink wrapping (with heat treatment) is performed on the outer peripheral surface, etc., of which the content is not filled, with the movable bottom member incorporated in the container body 1 By minimizing the influence of such as, can prevent the deterioration of the sealing performance of the movable bottom member against the inner peripheral surface of the container body,
It is what I did.

以上のシール性の担保およびシール性能の劣化防止の機能を併せ備えた素材として上述のゴム材や熱可塑性エラストマーを用いている。   The rubber material and the thermoplastic elastomer described above are used as a material having both the above-described sealing performance guarantee and the sealing performance deterioration preventing function.

なお、シール用外側部材とその内側のプラスチック部材とからなる可動底部材3の製作に際して、
(21)ゴム製のシール用外側部材を用いる場合は、当該外側部材を内側プラスチック部材に嵌合させ、
(22)熱可塑性エラストマー製のシール用外側部材を用いる場合は、当該外側部材および内側プラスチック部材を2色成形する。
In manufacturing the movable bottom member 3 composed of an outer member for sealing and a plastic member inside the sealing member,
(21) When using an outer member for sealing made of rubber, the outer member is fitted to the inner plastic member,
(22) When an outer member for sealing made of thermoplastic elastomer is used, the outer member and the inner plastic member are molded in two colors.

エアレスポンプ機構の周知の内容物吐出動作は次のとおりである。
先ず、キャップ10を取り外してから操作ボタン9を押圧すると、当該操作ボタンおよびこれと一体のステムが下動してハウジング内部空間域B(=上流側の吸込弁,下流側の吐出弁やステムなどで画定される吐出側の内容物収容空間域)の容量が減少する。
The known contents discharge operation of the airless pump mechanism is as follows.
First, when the operation button 9 is pressed after the cap 10 is removed, the operation button and the stem integrated therewith move down, and the housing internal space B (= upstream suction valve, downstream discharge valve, stem, etc.) The volume of the discharge-side content storage space area defined by (1) is reduced.

この容量減少にともないハウジング内部空間域Bが加圧されて吐出弁が開き、当該内部空間域に貯留されていた液状内容物は吐出弁から操作ボタン9の通路部分9aを経て孔部9bから外部空間域に吐出される。このとき吸込弁は勿論閉じたままである。   As the capacity is reduced, the internal space B of the housing is pressurized to open the discharge valve, and the liquid content stored in the internal space is discharged from the hole 9b through the passage portion 9a of the operation button 9 from the discharge valve. It is discharged into the space area. At this time, of course, the suction valve remains closed.

そして、利用者が操作ボタン9の押圧操作をやめると、操作ボタン9およびこれと一体のステムは、ハウジング内部のコイルスプリング(図示省略)の弾性作用により上方向に移動して静止モード位置に復帰する。   When the user stops pressing the operation button 9, the operation button 9 and the stem integral therewith are moved upward by the elastic action of a coil spring (not shown) inside the housing to return to the stationary mode position. To do.

操作ボタン9の復帰動作にともなってハウジング内部空間域Bの容積が増え、当該内部空間域の圧力が低下する。この圧力低下により吸込弁が開き、容器本体内部空間域Aに収容されている液状内容物がハウジング内部空間域Bに流入する。このとき吐出弁は閉じている。そして双方の内部空間域の圧力差が略なくなった時点でハウジング内部空間域Bの吸込弁は閉じて静止モードに移行する。ハウジング内部空間域Bに流入した液状内容物は次の操作ボタン押圧時の吐出対象内容物である。   As the operation button 9 returns, the volume of the housing internal space B increases, and the pressure in the internal space decreases. The suction valve is opened by this pressure drop, and the liquid content contained in the container body internal space area A flows into the housing internal space area B. At this time, the discharge valve is closed. Then, when the pressure difference between the two internal space regions is almost eliminated, the suction valve in the housing internal space region B is closed and the mode is changed to the stationary mode. The liquid content flowing into the housing internal space B is the content to be discharged when the next operation button is pressed.

ここで容器本体内部空間域Aの液状内容物がハウジング内部空間域Bへ流入することにより、内部空間域Aの圧力が大気圧より低くなる。   Here, when the liquid content in the container body internal space area A flows into the housing internal space area B, the pressure in the internal space area A becomes lower than the atmospheric pressure.

その結果、可動底部材2,3は底蓋4の側の大気圧の作用で図示上方向に移動する。なお、可動底部材2,3と底蓋4との間の空間域は孔部4aを介して常に外部空間と連通している。   As a result, the movable bottom members 2 and 3 move upward in the drawing by the action of atmospheric pressure on the bottom lid 4 side. The space between the movable bottom members 2 and 3 and the bottom lid 4 is always in communication with the external space through the hole 4a.
