Description

【０００１】
【産業上の利用分野】
本発明は、クリーム状物吐出容器に関する。
【０００２】
【従来の技術】
例えば、特開平5‐319467号公報にはシリンダを容器体内に垂下し、該容器体の口頸部に、上記シリンダ及び該シリンダ内から上下動可能に起立する作動部材からなるポンプを装着し、該ポンプの作動により、上記容器体内面に付設した密閉袋内のクリーム状物を吐出可能なポンプ付き容器が開示されている。該ポンプ付き容器は、吐出に伴う収納物の減少に応じて、袋が収縮変形して内部が負圧化しないから、クリーム状物を円滑に吐出できる。上記ポンプでは、上記シリンダ下端から垂下する吸上げパイプの外面に上下方向に長い凹条または突条を形成するとともに、吸上げパイプの下端部に複数の吸引用割溝を穿設して、収縮により袋がシリンダ及び吸上げパイプと密着しても割溝が両者の間の通路を形成して、吸上げパイプ下端の吸込み口が塞がれないようにしている。
【０００３】
また上記公報には、可撓性に富む袋を容器体の内壁全面に剥離可能にブロー成形で一体形成した積層ボトルが開示されている。該積層ボトルは袋を容器体内に装填する手間が省け、更にボトルの外観形状が変化しないという利点がある。
【０００４】
【発明が解決しようとする課題】
上述した積層ボトルにクリーム状物を装填して、上記容器用ポンプを組み付け、この状態で容器用ポンプを作動させてクリーム状物を吐出すると、該クリーム状物減少により袋が収縮するに対して容器体は変形しないから、該容器体に穿設した外気吸入孔を通って該容器と袋との間に入り、このようにしてまず外気吸入孔に近接する袋部分がシリンダ側へ引き寄せられ、ついで順次その袋部分の周辺部分が引き寄せられて袋内クリーム状物が吐出されることとなる。
【０００５】
一方容器体口頸部の上端部に接着されている袋口頸部の上端部は、容器体口頸部の上端部から剥離不能としてあるから、該袋口頸部内面と該内面と対向するシリンダ部分間の隙間内に入っているクリーム状物は、その吸引に先立ってその下方袋部分内クリーム状物が吸引され、その袋部分がシリンダ外面へ密着することで上記隙間内に入っていたクリーム状物は吸引路を失うこととなり、このようにしてその口頸部部分内に入っていたクリーム状物は吸引されることなく、そのまま廃棄されることとなる欠点があった。
【０００６】
また、このような欠点防止のため、上記口頸部内方の間隙内にクリーム状物が入らないよう、袋内へのクリーム状物充填量を調整することは可能であるが、このようにすると袋内クリーム状物吸引の途中で上記間隙内空気も吸引することとなり、するとノズルから吐出されるクリーム状物内に加圧された空気が混入することとなり、該加圧空気吐出の際、クリーム状物を飛散させることとなる欠点があった。
【０００７】
請求項１記載の発明は、上記事情に鑑みなされたもので、容器体２の内壁全面へ剥離可能に付着した可撓性に富む肉薄の袋６内へ垂設したポンプ装置８のシリンダ11外面と、上記容器体２の口頸部５に付着した袋６の口頸部６ａ内面との隙間に、該隙間を埋めるシール部材22を嵌合して該隙間内にクリーム状物や空気が残らないよう設けたものである。
【０００８】
請求項２記載の発明は、容器体２の口頸部５内面へ、該内面に付着させた袋６の口頸部６ａを介して嵌合させた筒体30下端から斜下内方へ突設した弾性内向きフランジ31内周縁をシリンダ11外周面へ圧接するシール材28で袋口頸部６ａの下端部を閉塞し、もって上記隙間内にクリーム状物や空気が残らないようにしたクリーム状物吐出容器を提供することを目的とする。
【０００９】
請求項３記載の発明は、上記請求項１及び請求項２記載の目的を有するとともに、ブロー成形により形成されるピンチオフ部に設けた隙間を上記エアー導入部とすることで、穿孔工程を省いたコストの安価なクリーム状物吐出容器を提供することを目的とする。
【００１０】
請求項４記載の発明は、上記請求項１，請求項２，及び請求項３記載の目的を有するとともに、ポンプ装置８のシリンダ11の下端部から、横断面十字形状の吸上げガイド杵33を垂下させることで、容器体内面から剥離した袋６がシリンダ11及び吸上げガイド杵33に密着したときに、吸上げガイド杵33と袋６との間に通路を形成し、シリンダ11下端の吸込み孔を閉塞しないようにしたクリーム状物吐出容器を提供することを目的とする。
【００１１】
【課題を解決するための手段】
上記目的を達成するために、第１の手段としては、可撓性に富む肉薄シート製の袋６を内壁全面へ剥離可能に付着させた容器体２と、該容器体の口頸部５に装着させて上記袋６内へ垂設させた、底部内面に吸込み弁10を有するシリンダ11、及び該シリンダ内から上方付勢されて起立する、下端に筒状ピストン14を有するステム15上部にノズル16付きヘッド17を嵌着させた作動部材12を備えたポンプ装置８とからなり、該ポンプ装置の作動により、シリンダ11内のクリーム状物をノズル16から吐出するクリーム状物吐出容器において、上記容器体２の口頸部５内面に付着させた袋の口頸部６ａと上記シリンダ11との隙間に、外周面を上記袋の口頸部６ａ内面全体へ、かつ内周面を上記シリンダ11外周面へそれぞれ気密に圧接させた状態で嵌入して、上記袋口頸部６ａを容器体口頸部５との間で挟着する筒状のシール部材22と、上記口頸部５を除く容器体壁面の一部に形成したエアー導入部とを設けた。
【００１２】
また第２の手段として、可撓性に富む肉薄シート製の袋６を内壁全面へ剥離可能に付着させた容器体２と、該容器体の口頸部５に装着させて上記袋６内へ垂設させた、底部内面に吸込み弁10を有するシリンダ11、及び該シリンダ内から上方付勢されて起立する、下端に筒状ピストン14を有するステム15上部にノズル16付きヘッド17を嵌着させた作動部材12を備えたポンプ装置８とからなり、該ポンプ装置の作動により、シリンダ11内のクリーム状物をノズル16から吐出するクリーム状物吐出容器において、上記容器体２の口頸部５内面へ、該内面に付着させた袋６の口頸部６ａを介して筒体30を気密に圧接し、かつ上記シリンダ11外周面へ、上記筒体30下端から斜下内方へ突設させた内向きフランジ31の内周縁を気密に圧接するシール材28と、上記口頸部５を除く容器体壁面の一部に形成したエアー導入部とを設けた。
【００１３】
更にまた第３の手段として、上記第１又は第２の手段を有するとともに、ブロー成形により形成されるピンチオフ部に設けた隙間をエアー導入部として用いたものである。
【００１４】
更にまた第４の手段として、上記第１、２又は第３の手段を有するとともに、上記シリンダ11の下端部へ、上端部を嵌着させて横断面十字形状の吸上げガイド杵33を容器体２内下方まで設けたものである。
【００１５】
【作用】
図１状態において、ヘッド17と嵌合筒20との螺合を解除すると、バネにより作動部材12が上昇し、シリンダ11内が負圧化する。該負圧化により、吸込み弁10が開放してシリンダ11内には袋６内のクリーム状物が吸上げられる。この際、クリーム状物が減少するに伴い、容器体２内壁から袋６が剥離して収縮するので、袋６内は負圧化しない。
【００１６】
ヘッド17を介して作動部材12を押下げると吸込み弁10が閉じ、シリンダ11内で加圧されたクリーム状物は、ステム15内を通ってノズル16から吐出する。上記操作反復により、クリーム状物が減少し、最終的には収縮した袋６がシリンダ11及び吸上げガイド杵33に密着するが、容器体２及び袋６の各口頸部とシリンダ11との間にはシール部材22、またはシール材28が嵌合されているから、それ等口頸部とシリンダ11との間隙にクリーム状物が残ることなく、また吸上げガイド杵33が有する縦溝34が通路を形成するので、シリンダ11下端の吸込み孔が塞がれることがなく、よって全量吐出することができる。
【００１７】
【実施例】
図１は本発明のクリーム状物吐出容器１を示す。該クリーム状物吐出容器は、容器体、ポンプ装置、及びシール部材とからなる。以下、本発明の実施例について説明するが、上記容器体及びポンプ装置は公知であるから、これらの構成については簡単に述べる。
【００１８】
上記容器体２は胴部３上部から肩部４を介して口頸部５を起立しており、上記容器体２の内壁全面に、可撓性に富む肉薄シート製の袋６を剥離可能に付着している。なお、上記容器体２と袋６とを異なる材質の合成樹脂材を用いて、これらをブロー成形で一体形成して、剥離可能な内外二層からなる積層容器としてもよい。
【００１９】
上記口頸部５外面に、後述する装着筒を固定する螺条を周設している。また口頸部５に近接する肩部分にエアー導入部としての透孔７を穿設しており、該透孔７は袋６内の収納物が減少して剥離するときに、容器体内負圧化で外気を導入する。なお、本実施例では袋６内の収納物減少に伴う剥離を良好に行うために、上記袋６にクリーム状物を装填する以前に、透孔７からエアーを吹き込んで、該エアー導入部周辺の袋部分をを容器体２から剥離している。また図示例では透孔７を肩部４に穿設したが、該透孔は例えば容器体２の底部に穿設してもよい。なお、上記エアー導入部はブロー成形により容器体に形成されるピンチオフ部の一部、例えば図２が示すように、容器体の底部に形成したピンチオフ部の一部を剥離させた隙間７ａであってもよい。上記ピンチオフ部の剥離は、ブロー成形後に容器体２に衝撃や力を加えること等で行う。
【００２０】
上記ポンプ装置８は、袋６内に垂設され、吸込み弁10を底部内面に設けたシリンダ11と、該シリンダ内から上下動可能に起立する作動部材12とからなり、既述口頸部５に螺合した装着筒13を介して容器体２に装着される。上記作動部材12は、シリンダ11内から上方付勢されて起立する、下端に筒状ピストン14を有するステム15と、該ステムの上部に嵌着させたノズル16付きヘッド17とで構成している。上記シリンダ11下端部内からは、図１が示すように、該下端部に上端部を嵌着させて吸上げガイド杵33を垂下しており、該吸上げガイド杵は袋６が外周に密着したときに、外面と袋６との間に吸込み路としての縦溝34が形成されるように、横断面を図３に示すように十字形状としている。
【００２１】
なお、図示例ではシリンダ11の上端から起立した係止筒18に内外二重の嵌合筒20を凹凸の嵌合手段を介して嵌着し、該嵌合筒の内筒20ａ内面へ作動部材12の上部を螺合させて、該作動部材を付勢に抗して押下げた状態を保持させている。またシリンダ11内を棒状部材21を設けている。上述したポンプ装置８の作動部材12を螺脱し、該作動部材の上下動を反復することで、袋６内の収納物を吐出することができる。
【００２２】
上記構成において、本発明では、上記容器体２の口頸部５内面に付着させた袋口頸部６ａと上記シリンダ11との隙間にシール部材22を嵌入して、袋６を密封した。該シール部材22は図１が示す第１実施例において、外周面が袋口頸部６ａの内面全体に気密に圧接する外筒23と、該外筒の下端から内方へ突出し、内周縁が上記シリンダ11外周面に当接する内向きフランジ24と、該内向きフランジの内周縁から起立し、上記シリンダ11外周面に気密に嵌合する内筒25とからなる。なお、シール部材22底部は図示のようにやや下方まで垂下してもよい。また、上記外筒22の上端には外向きフランジ26を付設して容器体口頸部５の上端面と装着筒13の内向きフランジ下面とで挟持させてもよく、このようにすることで該シール部材が容器体内へ脱落することを防止できる。なお、該シール部材22は、図４に示す第２実施例のように、中実のシール部材27例えば発砲スチロールの筒状栓体であってもよい。該シール部材27の下端面は、口頸部５の下端と同じ位置にしている。
【００２３】
図５は上記シール材の形状を代えたクリーム状物吐出容器の第３実施例を示す。該実施例のシール材28は、上記容器体２の口頸部５内面へ、該内面に付着させた袋６の口頸部６ａを介して気密に圧接する筒体30と、該筒体下端から斜下内方へ突設させた内向きフランジ31とからなり、該内向きフランジの内周縁をシリンダ11外周面へ圧接するように形成している。図示例では上記筒体30の上端に付設した外向きフランジ32を容器体口頸部５の上端面と装着筒13の内向きフランジ下面とで挟持させている。なお、第２、第３実施例のように上記吸上げガイド杵33を省略する場合には、シリンダ11の下端吸込み孔が袋６で閉塞されるのを防止するために、容器体２の底部内面と袋６とを一部を固着する必要がある。また上記第２，第３実施例において、図１が示すように、シリンダ11下端部内からは、該下端部に上端部を嵌着させて吸上げガイド杵33を垂下してもよい。
【００２４】
【発明の効果】
請求項１記載の発明は既述構成とするもので、容器体２の口頸部５内面に付着させた袋６の口頸部６ａ内面と、ポンプ装置８のシリンダ11外面との間の隙間に、筒状のシール部材22を嵌入したので、その隙間内にクリーム状物又は空気が入ることなく、よってその隙間内クリーム状物がシリンダ内へ吸込みされないまま廃棄されたり、またその隙間内空気がクリーム状物中に混入してポンプ装置により加圧され、ノズルからの吐出時にクリーム状物を飛散させることもない。
【００２５】
請求項２記載の発明は既述構成とするもので、容器体２の口頸部５内面へ、該内面に付着させた袋６の口頸部６ａを介して筒体30を圧接し、該筒体下端に付設した内向きフランジ31の内周縁でシリンダ11外面を圧接するシール材28で、袋６を口頸部６ａ下端で気密にシールするようにしたから、上記請求項１記載の発明の場合と同様の効果を有するほか、シリンダ外周面へ気密に圧接させた内向きフランジ31を弾性内向きフランジとしたから、その弾性変形で多少の寸法誤差があっても、その内向きフランジ内周縁を気密にシリンダ外面へ圧接させることが容易であり、寸法誤差許容範囲を拡大して不良品を減少できる効果がある。
【００２６】
請求項３記載の発明は、上記請求項１又は請求項２記載の発明の効果を有するとともに、ブロー成形により形成されるピンチオフ部に設けた隙間をエアー導入部としたから、穿孔工程を省いて、その製造コストを安価にすることができる。
【００２７】
請求項４記載の発明は、上記請求項１から請求項３記載の何れかの発明の効果を有するとともに、シリンダ11の下端部へ上端部を嵌着させて、横断面十字形状の吸上げガイド杵33を容器体内下方まで垂下したから、袋６と吸上げガイド杵33との間に通路が形成され、剥離した袋６下部がシリンダ11の吸込み孔が塞がれるのを防止することができる。

The present invention relates to a creamy substance discharge container.
[0002]
[Prior art]
For example, in JP-A-5-319467, a cylinder is suspended in a container body, and a pump composed of the cylinder and an operating member standing up and down from the inside of the cylinder is attached to the mouth and neck of the container body. There is disclosed a container with a pump capable of discharging a cream-like substance in a sealed bag attached to the inner surface of the container body by the operation of the pump. The container with a pump can smoothly discharge a cream-like material because the bag shrinks and deforms and the inside does not become negative pressure in accordance with a decrease in stored items accompanying discharge. In the above pump, a recess or protrusion that is long in the vertical direction is formed on the outer surface of the suction pipe that hangs down from the lower end of the cylinder, and a plurality of suction split grooves are formed in the lower end of the suction pipe to contract. Thus, even if the bag is in close contact with the cylinder and the suction pipe, the dividing groove forms a passage between them so that the suction port at the lower end of the suction pipe is not blocked.
[0003]
Further, the above publication discloses a laminated bottle in which a flexible bag is integrally formed by blow molding so as to be peeled from the entire inner wall of a container body. The laminated bottle is advantageous in that it saves the trouble of loading the bag into the container and the appearance of the bottle does not change.
[0004]
[Problems to be solved by the invention]
When the cream bottle is loaded into the above-mentioned laminated bottle, the container pump is assembled, and the container pump is operated in this state to discharge the cream substance, the cream shrinks and the bag shrinks. Since the container body does not deform, it enters between the container and the bag through the outside air suction hole drilled in the container body, and in this way, the bag portion adjacent to the outside air suction hole is first drawn toward the cylinder side, Subsequently, the peripheral portion of the bag portion is successively drawn and the cream-like material in the bag is discharged.
[0005]
On the other hand, the upper end of the bag mouth neck that is bonded to the upper end of the container body neck is not peelable from the upper end of the container mouth neck, so that the inner surface of the bag mouth neck faces the inner surface. Prior to the suction, the cream-like material in the gap between the cylinder portions was sucked into the lower bag portion, and the bag portion was in the gap by adhering to the outer surface of the cylinder. The cream-like material loses the suction path, and thus the cream-like material contained in the mouth-neck portion is not sucked but is discarded as it is.
[0006]
In order to prevent such defects, it is possible to adjust the filling amount of the cream-like material in the bag so that the cream-like material does not enter the gap inside the mouth and neck. Then, the air in the gap will also be sucked in the middle of the suction of the cream-like material in the bag, and then the pressurized air will be mixed in the cream-like material discharged from the nozzle. There was a drawback that would cause the creamy material to scatter.
[0007]
The invention described in claim 1 has been made in view of the above circumstances, and the outer surface of the cylinder 11 of the pump device 8 suspended in the thin flexible bag 6 attached to the entire inner wall of the container body 2 so as to be peelable. And a seal member 22 that fills the gap is formed in the gap between the mouth and neck 6a of the bag 6 attached to the mouth and neck 5 of the container body 2 so that a cream or air remains in the gap. It is provided so that there is no.
[0008]
The invention according to claim 2 projects obliquely inwardly from the lower end of the cylindrical body 30 fitted to the inner surface of the mouth neck portion 5 of the container body 2 via the mouth neck portion 6a of the bag 6 attached to the inner surface. A cream material in which the lower end of the bag mouth neck 6a is closed with a sealing material 28 that presses the inner peripheral edge of the elastic inward flange 31 to the outer peripheral surface of the cylinder 11 so that no cream or air remains in the gap. An object is to provide a discharge container.
[0009]
The invention described in claim 3 has the objects described in claims 1 and 2 above, and omits the perforation process by using a gap provided in the pinch-off part formed by blow molding as the air introduction part. An object is to provide a low-cost cream-like material discharge container.
[0010]
The invention described in claim 4 has the objects described in claims 1, 2, and 3 above, and a suction guide rod 33 having a cross-shaped cross section is formed from the lower end of the cylinder 11 of the pump device 8. When the bag 6 peeled off from the inner surface of the container body is brought into close contact with the cylinder 11 and the suction guide rod 33, a passage is formed between the suction guide rod 33 and the bag 6, and the lower end of the cylinder 11 is sucked. It aims at providing the cream-like thing discharge container which did not obstruct | occlude a hole.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, as a first means, a container body 2 in which a thin flexible sheet bag 6 is attached to the entire inner wall so as to be peeled off, and a mouth and neck part 5 of the container body are provided.

[Action]
In the state of FIG. 1, when the screwing of the head 17 and the fitting cylinder 20 is released, the operating member 12 is raised by the spring, and the inside of the cylinder 11 becomes negative pressure. Due to the negative pressure, the suction valve 10 is opened and the cream-like material in the bag 6 is sucked into the cylinder 11. At this time, as the cream-like material decreases, the bag 6 peels off from the inner wall of the container body 2 and contracts, so that the inside of the bag 6 does not become negative pressure.
[0016]
When the operating member 12 is pushed down via the head 17, the suction valve 10 is closed, and the cream-like material pressurized in the cylinder 11 is discharged from the nozzle 16 through the stem 15. By repeating the above operation, the cream-like material is reduced, and the shrunken bag 6 is finally brought into close contact with the cylinder 11 and the suction guide rod 33. Since the sealing member 22 or the sealing material 28 is fitted between them, a cream-like object does not remain in the gap between the mouth neck portion and the cylinder 11, and the longitudinal groove 34 of the suction guide rod 33 is provided. Since this forms a passage, the suction hole at the lower end of the cylinder 11 is not blocked, so that the entire amount can be discharged.
