【発明の属する技術分野】
本発明は、ポンプ部材の突刺し筒を内容器に突き刺すだけで内容物を取り出すことができる詰め替え用ポンプ付き容器に関する。
【0002】
【従来の技術】
従来、各家庭等で使用されている液体洗剤等の詰め替え用の包装袋としては自立性袋の形状が一般的であり、小出し容器に洗剤を詰め替えるには、通常の自立性袋の場合は上端角部をカットして開口を形成してその開口から小出し容器に詰め替える方法により、また、上端部に注出口が形成された自立性袋の場合は注出口から小出し容器に詰め替える方法により行われている。しかしながら、上記のようにして詰め替える場合には、小出し容器の口部が狭いこともあって、詰め替えに手間がかかる上に詰め替えの際に内容物を零してしまうおそれがあった。また、詰め替え時に内容物に外気が混入するので内容物の変質や微生物の繁殖等の問題があり、液体歯磨き等のように口に入れて使用する内容物の包装用としては好ましくないという欠点があった。
【0003】
それらの欠点を改良した、小出し容器に内容物を詰め替える必要のない詰め替え用ポンプ付き容器としては、特開平7−172466号に記載されているような、合成樹脂からなる筒状で自立型の袋の上端を、未延伸ナイロンとポリオレフィン系樹脂フィルムからなるラミネートフィルムをヒートシールして閉じた液体収納袋を、小出し用の容器体の内部に収納し、ポンプ部材を備えた蓋体を容器体の上端に取り付け、ポンプ部材のチューブを液体収納袋に突き刺して内容物を取り出す構成のもの、特願平9−257690号に記載されているような、可撓性のカップ状容器に内容物を充填し突刺密封性フィルムにて口部を密封した内容器を小出し用の容器体の内部に収納し、ポンプ部材を備えた蓋体を小出し容器体の上端に取り付けてポンプ部材の突刺し筒を内容器の突刺密封性フィルムに突き刺して内容物を取り出す構成のもの等が知られている。
上記の小出し容器においては、ポンプ部材のチューブを自立型の液体収納袋に突き刺す際に、ないしはポンプ部材の突刺し筒を内容器の突刺密封性フィルムに突き刺す際に、突き刺しが完了するまで、突き刺し位置をずらさないように且つ突き刺す角度が変わらないようにするのが困難であり、突き刺し部における密封性を確保して気密性を保持するのが難しいという欠点があった。
【0004】
【発明が解決しようとする課題】
本発明の目的は、ポンプ部材の突刺し筒を内容器に突き刺した際に、突き刺し部における密封性を確保して気密性を保持できるようにした詰め替え用ポンプ付き容器を提供することである。
【0005】
【課題を解決するための手段】
開口部の周縁にフランジを有する容器体と突刺し筒を備えたポンプ部材が取り付けられた蓋体とからなり、蓋体は蓋本体の下部に段部を介して突刺し筒より長い筒状体が延設され、筒状体の内径が容器体のフランジの外径よりやや大きくされ、突刺し筒が段部より下方に位置し、蓋体を容器体に取り付けた際に段部が容器体のフランジに当接する構成の詰め替え用ポンプ付き容器である。この場合、内容物が充填され密封されたフランジを有する圧潰性の内容器を容器体の内部に装填して、蓋体の筒状体を容器体の開口部に被せて押し下げるだけで、蓋体の段部が容器体のフランジに当接して蓋体の取り付けが完了した時点で突刺し筒が内容器の内部に突き刺さるので、この状態でポンプ部材を操作することにより内容物を取り出すことができる。また、突刺し筒の尖った先端が蓋体の筒状体の内部に収納された状態であるので、容器体に蓋体を取り付ける際に誤って突刺し筒で手を怪我するようなこともない。
【0006】
上記の詰め替え用ポンプ付き容器において、容器体の周壁の下方部の外面に円周方向に配置された3箇所以上の上下方向のリブが形成され、リブの上端に傾斜部が形成され、リブの外端の下部にそれぞれ突起が形成され、リブに外接する円の直径が筒状体の内径よりやや小さくされ、筒状体の上下方向の長さをリブの上下方向の長さと突刺し筒の長さの和より長くした構成とすることにより、容器体の内部に圧潰性の内容器を装填して、蓋体の筒状体を容器体の開口部に被せて押し下げて蓋体を容器体に取り付ける際に、突刺し筒の先端が内容器の上面に接する時点で、筒状体の下端はリブに達し、蓋体は真っ直ぐに誘導されるため、突刺し筒は容器体の開口部の面に垂直方向に突き刺され突き刺しが完了するまでその角度は変化しないし、突き刺し位置も変化しない。したがって、突刺し筒を突き刺した部分における密封性が確保され気密性を保持することができるので、ポンプ操作により内容物を取り出していった際に、内容器内に空気が進入することがなく、取り出された容積だけ内容器の容積が減少して内容器が圧潰され、内容物を最後まで残さず取り出すことができる。
【0007】
【発明の実施の形態】
以下、図面を引用して本発明の実施の形態を説明する。
図1は本発明の詰め替え用ポンプ付き容器の実施形態を示す縦断面図、図2は図1におけるI−I断面図、図3は実施形態における内容物を取り出す状態を示す縦断面図であって、1は容器体、11はフランジ、12は周壁、13は傾斜部、14はリブ、15は突起、16は台部、2は蓋体、21は蓋本体、22は段部、23は筒状体、3はポンプ部材、4は突刺し筒、5は内容器、51は内容器フランジ、6は突刺密封性フィルム、7は内容物をそれぞれを表す。
【0008】
本発明の詰め替え用ポンプ付き容器の実施形態は、図1、図2に示すとおりであって、容器体1と蓋体2とから構成されている。容器体1は円形の開口部の周縁にフランジ11を有する底細りの円筒状であり、周壁12の下部の外面に円周方向に均等に配置された4箇の上下方向に延びるリブ14が形成され、リブ14の上部が傾斜部13とされるとともにリブ14の外端の下端近傍に突起15が形成され、リブ14の下端にはリブ14の外端より外側に広がる台部16が形成され、リブ14に外接する円の直径と容器体1の開口部の周縁に形成されたフランジ11の外径とが同一寸法になるように設定されている構成である。本実施形態においては、リブ14は容器体1の周壁12の下部の外面に形成され、リブ14の上部は傾斜部13とされた形状としているが、これは、容器体1をポリプロピレン等の樹脂を使用して射出成形により製造する際の作業性を良くするように考慮したものであって、リブ14を容器体1の周壁12の外面に上下方向にフランジ11と台部16間の全長にわたって設けるようにしてもよい。
【0009】
蓋体2は、突刺し筒4を備えたポンプ部材3が上部の中央に取り付けられたドーム状の蓋本体21の下部に段部22を介して筒状体23が延設され、筒状体23の上下方向の長さはリブの上下方向の長さと突刺し筒の長さの和より長くされ、ポンプ部材3の突刺し筒4は段部22より下方に位置するように取り付けられ、筒状体23の内部に容器体1の開口部の周縁のフランジ11に被さるように、筒状体23の内径は容器体1のフランジ11の外径よりやや大きめに設定されている構成である。蓋体2をこの形状とすることにより、突刺し筒4が筒状体23の内部に隠れた状態であるので、蓋体2を容器体1に取り付ける際に突刺し筒4にて怪我をするおそれもない。本実施形態においては、蓋本体21の形状をドーム状としているが角型としてもよくその形状は任意である。
【0010】
容器体1のフランジ11上に内容器5のフランジ51を重ねた状態で容器体1の内部に内容器5を装填して蓋体2を取り付けた状態は、図3に示すとおりである。内容器5はフランジ51を有する圧潰可能な容器であり内部に内容物7を充填した後に突刺密封性フィルム6をフランジ51に熱接着することにより口部を密封した構成である。容器体1の内部に内容器5を装填して、蓋体2の筒状体23を容器体1の開口部に被せ、フランジ11の外周が筒状体23の内面に接する状態で蓋体2を押し下げることにより、蓋体2の段部22の下面と容器体1のフランジ11の上面間で内容器5のフランジ51を挟持し、容器体1の周壁12の下部に設けられたリブ14の外端の突起15により筒状体23がリブ14の外端間で固定された状態となり、容器体1への蓋体2の取り付けが完了する。この状態でポンプ部材3の下端に取り付けられた突刺し筒4が内容器5の開口部を覆っている突刺密封性フィルム6を突き刺して内容器5の内部に進入するので、ポンプ部材3を操作するにより内容物7を取り出すことができる。
【0011】
蓋体2の筒状体23を容器体1の開口部に被せて蓋体2を押し下げる際に、筒状体23の下端がリブ14の上端に達するまでは斜めに押し下げられることもあるが、筒状体23の下端が傾斜部13を通過してリブ14に達した時点で蓋体2は容器体1の開口部の面に垂直に押し下げられる。一方、筒状体23の上下方向の長さがリブ14の上下方向の長さと突刺し筒4の長さの和により長くされているので、筒状体23の下端がリブ14の上端に達した際に突刺し筒4の先端が突刺密封性フィルム6に達していない。筒状体23の下端がリブ14の上端に達した後は筒状体23の内面とリブ14の外端とが接した状態で蓋体2は容器体1の開口部の面、即ち内容器5の突刺密封性フィルム6の面に垂直に押し下げられるので、突刺し筒4の先端が突刺密封性フィルム6に接触した状態から突き刺しが完了するまで、突刺密封性フィルム6の面に垂直に突き刺される。したがって、突刺し筒4の突き刺し位置および角度が変わることがなく、突き刺し部における突刺し筒4と突刺密封性フィルム6間の密封性が確保され気密性が保持される。
【0012】
図3に示す状態にて、ポンプ部材3を操作することにより、突刺し筒4をとおして内容物7を取り出すことができる。内容物7が取り出されて内容器5内の内容物7が減少してゆくと、突刺し筒4と突き刺された突刺密封性フィルム6の突き刺し部の気密性が保持されているので、外部の空気が内容器5内に進入することがなく、また、内容器5のフランジ51が容器体1のフランジ11と蓋体2の段部22下面との間で挟持された状態であるが、内容器5のフランジ51と容器体1のフランジ11間が気密性を保つほど強く押さえられていないために、フランジ11とフランジ13の間から容器体1と内容器5の間に外気が進入してくので、内容物5の減少した容積分だけ内容器5の容積が減少して圧潰される。ポンプ部材3を操作して内容物7を取り出し続けると、内容物7の取り出された容積だけ内容器5の容積が減少して圧潰されてゆき、内容器5が完全に圧潰されて突刺し筒4の周辺および突刺密封性フィルム6の内面に密着した状態となって、内容器5に充填された内容物7を残らず取り出すことができる。この詰め替え用ポンプ付き容器を家庭に備えておくことにより、使い終わった際に新しい内容器を新しいものと取り替えるだけで繰り返し使用できる。
【0013】
本発明の詰め替え用ポンプ付き容器にて使用する内容器5は圧潰可能な容器である。内容器の構成は、ポリオレフィン系樹脂層とエチレン−ビニルアルコール共重合体(EVOH)ないしはポリ塩化ビニリデン(PVDC)からなるガスバリアー性樹脂層とポリオレフィン系樹脂層との積層体にて構成される。ポリオレフィン系樹脂層としては、低密度ポリエチレン(LDPE)、線状低密度ポリエチレン(LLDPE)、ポリプロピレン(PP)、エチレン−プロピレン共重合体(EP)等が使用できる。内容器5の積層構成の具体例としては、LDPE/EVOH/LDPE、LLDPE/EVOH/LLDPE、LDPE/EVOH/EP、LLDPE/EVOH/EP、LDPE/EVOH/PP、LLDPE/EVOH/PP、EP/EVOH/EP等である。上記積層フイルムは多層押出により製造されるものであり、各層間の接着強度を強くするために各層間に接着樹脂層を入れた多層押出フイルムとしてもよい。厚さが0.5〜1.0mmの多層シートを使用して真空成形ないしは圧空成形することにより製造されるが、多層のブロー成形により製造することもできる。また、ガスバリヤー性を必要としない内容物を包装する用途の場合には、低密度ポリエチレン(LDPE)、線状低密度ポリエチレン(LLDPE)、ポリプロピレン(PP)、エチレン−プロピレン共重合体(EP)等からなる成形容器が使用できる。
【0014】
突刺密封性フィルム6としては、低密度ポリエチレン(LDPE)、線状低密度ポリエチレン(LLDPE)、中密度ポリエチレン(MDPE)、エチレン−酢酸ビニル共重合体(EVA)、アイオノマー(IO)およびエチレン−アクリル酸共重合体(EAA)、エチレン−エチルアクリレート共重合体(EEA)、エチレン−メタクリル酸共重合体(EMA)、エチレン−メチルメタクリレート共重合体(EMMA)等のエチレン−アクリル酸系モノマー共重合体からなるポリオレフィン系フィルムのいずれか、ないしは上記の2種類以上の樹脂からなる多層フィルムが使用される。多層構成のフィルムとすることにより突き刺し性、突き刺し密封性の優れたものとすることができる。多層構成のフィルムとしは、LLDPE/MDPE/LLDPE、LLDPE/EVA/LLDPE、LLDPE/IO/LLDPE、LLDPE/EAA/LLDPE、LLDPE/EEA/LLDPE、LLDPE/EMA/LLDPE、LLDPE/EMMA/LLDPE等である。多層の突刺密封性フィルムを製造するには共押出しが適しており、必要により層間に接着樹脂層を入れてもよい。突刺密封性フィルムの厚さとしては、0.10〜0.20mmが好ましく、3層構成とする場合の厚さの比率は、1.0:0.2〜0.8:1.0が好ましい。
【0015】
ガスバリヤー性の優れた突刺密封性フィルムとしては、上記のポリオレフィン系フィルムの外側に、ガスバリヤー性の優れたプラスチック層を積層した構成のものが使用できる。ガスバリヤー性の優れたプラスチック層としては、未延伸ナイロン(CN)、ポリ塩化ビニリデン(PVDC)コート未延伸ナイロン、エチレン−ビニルアルコール共重合体(EVOH)等が使用できる。ガスバリヤー性の優れた突刺密封性フィルムの構成としては、CN/接着層/LLDPE、CN/接着層/LLDPE/MDPE/LLDPE、PVDCコートCN/接着層/LLDPE、PVDCコートCN/接着層/LLDPE/MDPE/LLDPE、EVOH/接着層/LLDPE/MDPE/LLDPE等である。
【0016】
【発明の効果】
開口部の周縁にフランジを有する容器体と突刺し筒を備えたポンプ部材が取り付けられた蓋体とからなり、蓋体は蓋本体の下部に段部を介して突刺し筒より長い筒状体が延設され、筒状体の内径が容器体のフランジの外径よりやや大きくされ、突刺し筒が段部より下方に位置し、蓋体を容器体に取り付けた際に段部が容器体のフランジに当接する構成の詰め替え用ポンプ付き容器である。この場合、内容物が充填され密封された圧潰性の内容器を容器体の内部に装填して、蓋体の筒状体を容器体の開口部に被せて押し下げるだけで、蓋体の段部が容器体のフランジに当接して蓋体の取り付けが完了した時点で突刺し筒が内容器の内部に突き刺されるので、この状態でポンプ部材を操作することにより内容物を取り出すことができる。また、突刺し筒の尖った先端が蓋体の筒状体の内部に納まった状態であるので、容器体に蓋体を取り付ける際に誤って突刺し筒で手を怪我するようなこともない。
上記の詰め替え用ポンプ付き容器において、容器体の周壁の下方部に外面に円周方向に配置された3箇所以上の上下方向のリブが形成され、リブの上端に傾斜部が形成され、リブの外面の下部にそれぞれ突起が形成され、リブに外接する円の直径が筒状体の内径よりやや小さくされ、筒状体の上下方向の長さをリブの上下方向の長さと突刺し筒の長さの和より長くした構成とすることにより、容器体の内部に圧潰性の内容器を装填して、蓋体の筒状体を容器体の開口部に被せて押し下げて蓋体を容器体に取り付ける際に、突刺し筒の先端が内容器に接する時点で、筒状体はリブの部分に達しているので、突刺し筒は容器体の開口部の面に垂直方向に突き刺され突き刺しが完了するまでその角度は変化しないし、突き刺し位置も変化しない。したがって、突刺し筒を突き刺した部分における突刺し筒と内容器の突刺密封性フィルム間の密封性が確保され気密性を保持することができるので、ポンプ操作により内容物を取り出していった際に、内容器内に空気が進入することがなく、取り出された容積だけ内容器の容積が減少して内容器が圧潰されてゆくので、内容物を最後まで残さず取り出すことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a container with a refilling pump that can take out contents by simply piercing an inner container with a piercing tube of a pump member.
[0002]
[Prior art]
Conventionally, as a packaging bag for refilling liquid detergent used in each home, the shape of a self-supporting bag is common, and in order to refill detergent into a dispensing container, in the case of a normal self-supporting bag, the upper end This is done by cutting the corners to form an opening and refilling into a dispensing container from the opening, or in the case of a self-supporting bag with a spout formed at the upper end, refilling into a dispensing container from the spout. Yes. However, in the case of refilling as described above, the mouth portion of the dispensing container is narrow, so it takes time for refilling and there is a risk that the contents will be zeroed during refilling. In addition, since the outside air is mixed into the contents when refilling, there is a problem such as deterioration of the contents and propagation of microorganisms, and there is a disadvantage that it is not preferable for packaging contents used in the mouth like liquid toothpaste etc. there were.
[0003]
As a container with a refilling pump that does not require refilling the contents into a dispensing container that has improved those disadvantages, a cylindrical, self-supporting bag made of synthetic resin as described in JP-A-7-172466 A liquid storage bag closed by heat-sealing a laminate film made of unstretched nylon and a polyolefin-based resin film is stored inside the container body for dispensing, and a lid body having a pump member is attached to the container body. A flexible cup-shaped container filled with the contents as described in Japanese Patent Application No. 9-257690, which is attached to the upper end and has a structure in which the pump member tube is inserted into the liquid storage bag to take out the contents. The inner container, whose mouth is sealed with a piercing sealing film, is housed inside the dispensing container body, and a lid provided with a pump member is attached to the upper end of the dispensing container body to Those such configurations pierce the piercing tube member to puncture the sealing film of the inner container and the contents removed are known.
In the above dispensing container, when the tube of the pump member is pierced into the self-supporting liquid storage bag or when the piercing tube of the pump member is pierced into the piercing sealing film of the inner container, the piercing is completed until the piercing is completed. There is a drawback that it is difficult to prevent the position from being shifted and the angle to be pierced from changing, and it is difficult to maintain the airtightness by securing the sealing performance at the piercing portion.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to provide a refillable pump-equipped container that secures hermeticity at the pierced portion and maintains hermeticity when a piercing tube of a pump member is pierced into an inner container.
[0005]
[Means for Solving the Problems]
It consists of a container body having a flange at the periphery of the opening and a lid body to which a pump member having a piercing cylinder is attached, and the lid body is a cylindrical body that is longer than the piercing cylinder through a step portion at the lower part of the lid body. Is extended, the inner diameter of the cylindrical body is slightly larger than the outer diameter of the flange of the container body, the piercing tube is positioned below the stepped portion, and the stepped portion is placed in the container body when the lid is attached to the container body. It is a container with a refilling pump of the structure contact | abutted to this flange. In this case, the cover body can be obtained by simply loading a crushable inner container having a flange filled with the contents and sealing it into the container body, and covering the opening of the container body with the cylindrical body and pushing down. Since the piercing tube pierces the inside of the inner container at the time when the step portion of the container contacts the flange of the container body and the attachment of the lid body is completed, the contents can be taken out by operating the pump member in this state . In addition, since the sharp tip of the piercing tube is housed inside the cylindrical body of the lid body, when the lid body is attached to the container body, it may happen that the hand is accidentally injured by the piercing cylinder. Absent.
[0006]
In the above container with a refill pump, three or more vertical ribs arranged in the circumferential direction are formed on the outer surface of the lower part of the peripheral wall of the container body, an inclined part is formed at the upper end of the rib, Protrusions are formed in the lower part of the outer end, the diameter of the circle circumscribing the rib is slightly smaller than the inner diameter of the cylindrical body, and the vertical length of the cylindrical body is set to the vertical length of the rib and the piercing cylinder By adopting a configuration that is longer than the sum of the lengths, a collapsible inner container is loaded inside the container body, and the lid body is pushed down by covering the opening of the container body with the cylindrical body of the lid body. When the tip of the piercing tube comes into contact with the upper surface of the inner container, the lower end of the cylindrical body reaches the rib and the lid is guided straight, so that the piercing tube is positioned at the opening of the container body. The angle does not change until the piercing is completed Can stab position does not change. Therefore, since the sealing performance at the portion where the piercing tube is pierced is secured and the airtightness can be maintained, when the contents are taken out by the pump operation, air does not enter the inner container, The volume of the inner container is reduced by the removed volume, the inner container is crushed, and the contents can be taken out without leaving the last.
[0007]

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a longitudinal sectional view showing an embodiment of a container with a refill pump of the present invention, FIG. 2 is a sectional view taken along the line II in FIG. 1, and FIG. 3 is a longitudinal sectional view showing a state in which contents are taken out in the embodiment. 1 is a container body, 11 is a flange, 12 is a peripheral wall, 13 is an inclined part, 14 is a rib, 15 is a protrusion, 16 is a base part, 2 is a lid body, 21 is a lid body, 22 is a stepped part, 23 is Cylindrical body, 3 is a pump member, 4 is a piercing cylinder, 5 is an inner container, 51 is an inner container flange, 6 is a piercing sealing film, and 7 is a content.
[0008]
The embodiment of the container with a refill pump of the present invention is as shown in FIGS. 1 and 2, and is composed of a container body 1 and a lid body 2. The container body 1 is a bottomed cylindrical shape having a flange 11 at the periphery of a circular opening, and four vertically extending ribs 14 are formed on the outer surface of the lower portion of the peripheral wall 12 and are equally arranged in the circumferential direction. The upper portion of the rib 14 is an inclined portion 13, and a protrusion 15 is formed in the vicinity of the lower end of the outer end of the rib 14, and a base portion 16 that extends outward from the outer end of the rib 14 is formed at the lower end of the rib 14. In this configuration, the diameter of the circle circumscribing the rib 14 and the outer diameter of the flange 11 formed on the periphery of the opening of the container body 1 are set to have the same dimension. In the present embodiment, the rib 14 is formed on the outer surface of the lower portion of the peripheral wall 12 of the container body 1 and the upper portion of the rib 14 is formed as an inclined portion 13. This is because the container body 1 is made of resin such as polypropylene. The rib 14 is formed on the outer surface of the peripheral wall 12 of the container body 1 in the vertical direction over the entire length between the flange 11 and the base portion 16. You may make it provide.
[0009]
The lid 2 has a tubular body 23 extending through a step 22 at a lower portion of a dome-shaped lid body 21 in which a pump member 3 having a piercing tube 4 is attached at the center of the upper portion. The length in the vertical direction of 23 is longer than the sum of the length in the vertical direction of the rib and the length of the piercing tube, and the piercing tube 4 of the pump member 3 is attached so as to be positioned below the step portion 22. The inner diameter of the cylindrical body 23 is set to be slightly larger than the outer diameter of the flange 11 of the container body 1 so as to cover the flange 11 at the periphery of the opening of the container body 1 inside the cylindrical body 23. Since the piercing cylinder 4 is hidden inside the cylindrical body 23 by making the lid body 2 in this shape, the piercing cylinder 4 is injured when the lid body 2 is attached to the container body 1. There is no fear. In the present embodiment, the shape of the lid body 21 is a dome shape, but may be a square shape, and the shape is arbitrary.
[0010]
FIG. 3 shows a state in which the inner container 5 is loaded inside the container body 1 and the lid body 2 is attached while the flange 51 of the inner container 5 is overlapped on the flange 11 of the container body 1. The inner container 5 is a collapsible container having a flange 51, and has a structure in which the mouth is sealed by thermally bonding the puncture sealing film 6 to the flange 51 after filling the contents 7 inside. The inner container 5 is loaded inside the container body 1, the cylindrical body 23 of the lid body 2 is covered with the opening of the container body 1, and the outer periphery of the flange 11 is in contact with the inner surface of the cylindrical body 23. , The flange 51 of the inner container 5 is sandwiched between the lower surface of the step portion 22 of the lid body 2 and the upper surface of the flange 11 of the container body 1, and the rib 14 provided at the lower portion of the peripheral wall 12 of the container body 1 The cylindrical body 23 is fixed between the outer ends of the ribs 14 by the protrusions 15 at the outer end, and the attachment of the lid body 2 to the container body 1 is completed. In this state, the piercing tube 4 attached to the lower end of the pump member 3 pierces the piercing sealing film 6 covering the opening of the inner container 5 and enters the inner container 5, so that the pump member 3 is operated. Thus, the contents 7 can be taken out.
[0011]
When the cylindrical body 23 of the lid body 2 is put on the opening of the container body 1 and the lid body 2 is pushed down, it may be pushed down diagonally until the lower end of the cylindrical body 23 reaches the upper end of the rib 14. When the lower end of the cylindrical body 23 passes through the inclined portion 13 and reaches the rib 14, the lid body 2 is pushed down perpendicularly to the surface of the opening of the container body 1. On the other hand, since the vertical length of the cylindrical body 23 is increased by the sum of the vertical length of the rib 14 and the length of the piercing cylinder 4, the lower end of the cylindrical body 23 reaches the upper end of the rib 14. At this time, the tip of the piercing tube 4 does not reach the piercing sealing film 6. After the lower end of the cylindrical body 23 reaches the upper end of the rib 14, the lid body 2 is in a state where the inner surface of the cylindrical body 23 and the outer end of the rib 14 are in contact with each other. 5 is pushed down perpendicularly to the surface of the puncture sealing film 6 so that the piercing tube 4 is pierced perpendicularly to the surface of the puncture sealing film 6 from the state where the tip of the puncture tube 4 is in contact with the puncture sealing film 6 until the piercing is completed. It is. Therefore, the piercing position and angle of the piercing tube 4 do not change, and the sealing performance between the piercing tube 4 and the piercing sealing film 6 at the piercing portion is ensured and the airtightness is maintained.
[0012]
In the state shown in FIG. 3, the contents 7 can be taken out through the piercing tube 4 by operating the pump member 3. When the contents 7 are taken out and the contents 7 in the inner container 5 decrease, the airtightness of the piercing tube 4 and the piercing portion of the piercing sealing film 6 that has been pierced is maintained. Air does not enter the inner container 5 and the flange 51 of the inner container 5 is sandwiched between the flange 11 of the container body 1 and the lower surface of the step portion 22 of the lid body 2. Since the space between the flange 51 of the container 5 and the flange 11 of the container body 1 is not so strong as to keep airtightness, outside air enters between the container body 1 and the inner container 5 from between the flange 11 and the flange 13. Therefore, the volume of the inner container 5 is reduced by the reduced volume of the contents 5 and is crushed. When the pump 7 is operated and the contents 7 are continuously taken out, the volume of the inner container 5 is reduced by the volume of the contents 7 taken out, and the inner container 5 is completely crushed and the piercing tube 4 and the inner surface of the puncture sealing film 6 are brought into close contact with each other, so that the contents 7 filled in the inner container 5 can be taken out without any residue. By providing this container with a pump for refilling at home, it can be used repeatedly by simply replacing the new inner container with a new one when it is finished.

Specific examples of the laminated structure of the inner container 5 include LDPE / EVOH / LDPE, LLDPE / EVOH / LLDPE, LDPE / EVOH / EP, LLDPE / EVOH / EP, LDPE / EVOH / PP, LLDPE / EVOH / PP, EP / EVOH / EP or the like. The laminated film is manufactured by multilayer extrusion, and may be a multilayer extrusion film in which an adhesive resin layer is inserted between the layers in order to increase the adhesive strength between the layers. It is manufactured by vacuum forming or pressure forming using a multilayer sheet having a thickness of 0.5 to 1.0 mm, but it can also be manufactured by multilayer blow molding. In the case of packaging contents that do not require gas barrier properties, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), polypropylene (PP), ethylene-propylene copolymer (EP) A molded container made of, etc. can be used.
[0014]
The puncture sealing film 6 includes low density polyethylene (LDPE), linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), ethylene-vinyl acetate copolymer (EVA), ionomer (IO) and ethylene-acrylic. Ethylene-acrylic acid monomer copolymer such as acid copolymer (EAA), ethylene-ethyl acrylate copolymer (EEA), ethylene-methacrylic acid copolymer (EMA), ethylene-methyl methacrylate copolymer (EMMA) Either a polyolefin film made of coalescence or a multilayer film made of two or more of the above-mentioned resins is used. By using a multilayer film, it is possible to achieve excellent piercing properties and piercing sealing properties. Multi-layered films include LLDPE / MDPE / LLDPE, LLDPE / EVA / LLDPE, LLDPE / IO / LLDPE, LLDPE / EAA / LLDPE, LLDPE / EEA / LLDPE, LLDPE / EMA / LLDPE, LLDPE / EMMA / LLDPE, etc. is there. Co-extrusion is suitable for producing a multilayer puncture-sealing film, and an adhesive resin layer may be provided between the layers as necessary. The thickness of the puncture sealing film is preferably from 0.10 to 0.20 mm, and the ratio of the thickness in the case of a three-layer structure is preferably from 1.0: 0.2 to 0.8: 1.0. .
[0015]
As the puncture sealing film having excellent gas barrier properties, a film in which a plastic layer having excellent gas barrier properties is laminated on the outside of the polyolefin film can be used. As the plastic layer having excellent gas barrier properties, unstretched nylon (CN), polyvinylidene chloride (PVDC) -coated unstretched nylon, ethylene-vinyl alcohol copolymer (EVOH), or the like can be used. The structure of the puncture sealing film having excellent gas barrier properties is CN / adhesive layer / LLDPE, CN / adhesive layer / LLDPE / MDPE / LLDPE, PVDC coat CN / adhesive layer / LLDPE, PVDC coat CN / adhesive layer / LLDPE / MDPE / LLDPE, EVOH / adhesive layer / LLDPE / MDPE / LLDPE, etc.

【The invention's effect】
It consists of a container body having a flange at the periphery of the opening and a lid body to which a pump member having a piercing cylinder is attached, and the lid body is a cylindrical body that is longer than the piercing cylinder through a step portion at the lower part of the lid body. Is extended, the inner diameter of the cylindrical body is slightly larger than the outer diameter of the flange of the container body, the piercing tube is positioned below the stepped portion, and the stepped portion is placed in the container body when the lid is attached to the container body. It is a container with a refilling pump of the structure contact | abutted to this flange. In this case, a stepped portion of the lid is simply loaded by filling the sealed inner container filled with the contents into the container body, and pressing the cylindrical body of the lid over the opening of the container body and pushing down. Since the piercing tube is pierced into the inner container at the time when the attachment of the lid is completed by contacting the flange of the container body, the contents can be taken out by operating the pump member in this state. In addition, since the pointed tip of the piercing tube is inside the cylindrical body of the lid, there is no possibility of accidentally piercing the hand when attaching the lid to the container body. .
In the above-mentioned container with a refill pump, three or more vertical ribs arranged in the circumferential direction are formed on the outer surface of the lower part of the peripheral wall of the container body, an inclined part is formed at the upper end of the rib, Projections are formed on the lower part of the outer surface, the diameter of the circle circumscribing the rib is slightly smaller than the inner diameter of the cylindrical body, and the vertical length of the cylindrical body is set to the vertical length of the rib and the length of the piercing cylinder By making the structure longer than the sum of the length, a collapsible inner container is loaded inside the container body, and the lid body is pushed down by covering the opening of the container body with the cylindrical body of the lid body. When attaching, when the tip of the piercing tube comes into contact with the inner container, the cylindrical body has reached the rib portion, so the piercing tube is pierced perpendicularly to the surface of the opening of the container body and the piercing is completed Until then, the angle does not change, and the piercing position does not change. Therefore, since the sealing performance between the piercing tube and the piercing sealing film of the inner container at the portion where the piercing tube is pierced can be secured and the airtightness can be maintained, when the contents are taken out by the pump operation Since the air does not enter the inner container and the volume of the inner container is reduced by the extracted volume and the inner container is crushed, the contents can be taken out without leaving the last.
