Description

本発明は、内容物の充填容量が減るにしたがい外観形状が変形、減容していく容器本体を備えたポンプ付き薄肉容器に関するものであり、内容物の充填容量が減った場合であっても容器本体の外観形状の変形、減容を抑制し自立性を確保するとともに美観を安定的に保持しようとするものである。   The present invention relates to a thin-walled container with a pump having a container body whose outer shape is deformed and volume-reduced as the filling capacity of the contents decreases, and even when the filling capacity of the contents is reduced. It is intended to suppress the deformation and volume reduction of the outer shape of the container main body to ensure independence and to keep the aesthetic stability stably.

化粧料や整髪料、シャンプーあるいはリンス等を入れる容器としては、ハンディータイプや据え置きタイプに関わらずポンプを装着したものが多数上市されており、これにより容器内の内容物を衛生的、かつ効率的に注出することができるようになっている。   Many containers with cosmetics, hair styling, shampoo, rinse, etc. that are equipped with pumps are marketed regardless of the handy type or the stationary type, so that the contents in the container are hygienic and efficient. Can be poured out.

ところで、最近、この種の容器にあっては資源の有効活用、ゴミの減量化を図る観点から容器そのものの肉厚を薄くすることが求められているところ、容器の薄肉化は自立性を確保するのを困難とし、容器の外観形状を損なう等の種々の問題を生じさせることからその実現を図るにも限界があった。   Recently, in this type of container, it has been required to reduce the thickness of the container itself from the viewpoint of effective use of resources and reduction of garbage. It is difficult to achieve this, and various problems such as damage to the external appearance of the container are caused, so that there is a limit to achieving this.

この点に関する先行技術としては、内容物を入れる容器を柔軟な袋状の容器体とし、この容器体を内側に納める外ケース体を備えた液体吐出器が知れられている（例えば、特許文献１参照）。しかし、かかる液体吐出器では外ケース体を別途に用意する必要があり、また、袋状の容器体を取替えるだけとはいえ、その取替え作業が煩雑であり使い勝手がよいとはいえない。   As a prior art regarding this point, a liquid ejector including an outer case body in which a container for containing contents is a flexible bag-like container body and the container body is housed inside is known (for example, Patent Document 1). reference). However, in such a liquid ejector, it is necessary to prepare an outer case body separately. Further, although the bag-like container body is simply replaced, the replacement operation is complicated and not easy to use.

実開平５−３４１６７号公報Japanese Utility Model Publication No. 5-34167

本発明の課題は、外ケース体等の余計な部材を不要とし、内容物の充填容量が少なくなっても外観形状を損なうことのないポンプ付き薄肉容器を提案するところにある。   An object of the present invention is to propose a thin-walled container with a pump that does not require an extra member such as an outer case body and does not impair the external shape even when the filling capacity of the contents is reduced.

本発明は、内容物の充填空間を区画形成するとともに内容物の排出に伴って減容可能な薄肉の容器本体と、この容器本体の口部を通して充填空間の上部に吊り下げ保持され、エアシリンダー内でエアピストンを往復移動させることによって充填空間内に圧縮されたエアを供給するエアポンプとを備えたポンプ付き薄肉容器であって、
前記エアシリンダーに、エアを容器本体内に噴出させる時のみ開放する逆止弁を設け、前記エアピストンに容器本体内の圧力上昇により該逆止弁によるエアの噴出が不能になった場合に開放し、エアシリンダー内のエアを容器の外側へ向けて放出する圧力開放弁を設けたことを特徴とするポンプ付き薄肉容器である。 The present invention relates to a thin-walled container body that forms a filling space for contents and can be reduced as the contents are discharged, and is suspended and held above the filling space through the mouth of the container body. A thin-walled container with a pump comprising an air pump for supplying compressed air into a filling space by reciprocating an air piston in the interior,
The air cylinder is provided with a check valve that is opened only when air is jetted into the container body, and is opened when the air piston becomes unable to eject air due to a pressure increase in the container body. And a pressure-relief valve that discharges air in the air cylinder toward the outside of the container.

上記の構成になるポンプ付き薄肉容器において、前記圧力開放弁は、エアピストンの圧縮側からその反対側に向けて貫通する経路を有するケースと、このケース内でエアシリンダーの圧縮側に向けて弾性支持され、該経路の座面に当接して該経路を閉塞状態に保持する弁体とから構成されるものが本発明に有利に適合する。   In the thin-walled container with a pump configured as described above, the pressure release valve is elastic toward the compression side of the air cylinder and a case having a path that penetrates from the compression side of the air piston toward the opposite side. It is advantageously adapted to the present invention that it is constituted by a valve body that is supported and abuts against the seating surface of the path and holds the path in a closed state.

前記エアシリンダーの径方向内側には、容器本体内の内容物を噴出させる液用ポンプを設けることができ、液用ポンプとしては、内容物の排出経路を形成する液用シリンダーと、この液用シリンダー内でエアピストンと同期して排出経路を開閉する液用開閉弁と、この液用開閉弁に連係する中空ステムと、この中空ステムにつながり、該液用開閉弁の開放によって中空ステムを通して内容物を噴出させるノズルヘッドとを備えたものが適用される。   On the radially inner side of the air cylinder, a liquid pump for ejecting the contents in the container body can be provided. The liquid pump includes a liquid cylinder that forms a discharge path for the contents, and a liquid pump for the liquid. A liquid on-off valve that opens and closes the discharge path in synchronization with the air piston in the cylinder, a hollow stem linked to the liquid on-off valve, and the contents that pass through the hollow stem by opening the liquid on-off valve. A thing provided with the nozzle head which ejects an object is applied.

エアポンプを作動させることによって充填空間内にエアを供給するようにしたため、内容物の残量にかかわりなく容器本体は初期形状を保つこととなり、その結果として、自立性が確保されるとともに美観が保たれる。   Since air is supplied into the filling space by operating the air pump, the container body retains its initial shape regardless of the remaining amount of contents, and as a result, independence is ensured and aesthetics are maintained. Be drunk.

以下、図面を参照して本発明をより具体的に説明する。
図１は本発明にしたがうポンプ付き薄肉容器の実施の形態を示したものである。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows an embodiment of a thin-walled container with a pump according to the present invention.

図における１は内容物の充填空間Ｍを区画形成するとともに内容物の排出に伴って減容可能な薄肉の容器本体である。   In the figure, reference numeral 1 denotes a thin-walled container main body that partitions the filling space M of the contents and can be reduced in volume as the contents are discharged.

また、２は充填空間Ｍ内にエアを供給するエアポンプである。このエアポンプ２は、容器本体１の口部１ａを通して充填空間Ｍの上部に吊り下げ保持されるエアシリンダー２ａと、このエアシリンダー２ａ内で往復移動可能なエアピストン２ｂから構成されている。   Reference numeral 2 denotes an air pump for supplying air into the filling space M. The air pump 2 includes an air cylinder 2a that is suspended from an upper portion of the filling space M through the mouth portion 1a of the container body 1 and an air piston 2b that can reciprocate within the air cylinder 2a.

エアポンプ２のエアシリンダー２ａは、ディスク状の底壁２ａ１と、この底壁２ａ１の外縁部につながりその内側にエアの加圧空間を形成する周壁２ａ２からなっている。また、エアピストン２ｂはエアシリンダー２ａの内壁に沿って摺動しながら移動するディスクタイプのスライダー２ｂ１と、このスライダー２ｂ１の縁部に一体的に形成された摺動部材２ｂ２とから構成され、その中心部には中空ステムと一体になる例で示した筒体２ｂ３が形成されている。 Air cylinder 2a of the air pump 2 has a bottom wall 2a 1 of the disc-shaped, the peripheral wall 2a 2 that forms between air pressurized on the inside leads to the outer edge of the bottom wall 2a 1. The configuration air piston 2b is a slider 2b 1 of the disk type in which the movement while sliding along the inner wall of the air cylinder 2a, the sliding member 2b 2 Metropolitan integrally formed on the edge of the slider 2b 1 A cylindrical body 2b 3 shown in the example integrated with the hollow stem is formed at the center.

３はエアピストン２ｂのスライダー２ｂ１に設けられ、エアシリンダー２ａ内に外気（エア）を導入するときにのみ開放する外気導入弁、４はエアシリンダー２ａの底壁２ａ１に設けた例で示した三点式の逆止弁である。この逆止弁４は、加圧されたエアを容器本体１内に噴出する時にのみ開放する。 3 is an outside air introduction valve which is provided on the slider 2b 1 of the air piston 2b and is opened only when outside air (air) is introduced into the air cylinder 2a. 4 is an example provided on the bottom wall 2a 1 of the air cylinder 2a. This is a three-point check valve. The check valve 4 is opened only when pressurized air is ejected into the container body 1.

５はエアピストン２ｂのスライダー２ｂ１に設けられた圧力開放弁である。この圧力開放弁５は、スライダー２ｂ１に一体に形成され、エアピストン２ｂの圧縮側ｇから背面側ｇ１に向けて貫通する経路ｒが形成されたケース５ａと、このケース５ａ内でスプリング５ｂを介して弾性支持され、ケース５ａの座面に当接して経路ｒを閉塞する弁体５ｃと、スプリング５ｂの後端に当接するスプリング押え５ｄから構成されている。 5 is a pressure relief valve provided on the slider 2b 1 of the air piston 2b. The pressure release valve 5 is formed integrally with the slider 2b 1 and has a case 5a formed with a path r penetrating from the compression side g to the back side g 1 of the air piston 2b, and a spring 5b in the case 5a. And a spring presser 5d that abuts against the rear end of the spring 5b.

圧力開放弁５の弁体５ｃは、エアシリンダー２ａの圧縮側ｇに向けて押し付けられているが、容器本体１内の圧力が上昇しすぎて逆止弁４によるエアの噴出が不能になるような場合にはエアシリンダー２ａ内の圧力によって弁体５ｃがスプリング５ｂの付勢力に抗してエアピストン２ｂの背面側へ向けて押され、これにより該弁体５ｃが座面から離反して経路ｒが開となり、図１の要部拡大図の矢印の如く、経路ｒを通り抜けたエアは外気導入経路を通り抜けて大気へ放出されることとなり、容器本体１は少なくとも初期の外観形状を保持するのに必要な程度の圧力に保持される。   The valve body 5c of the pressure release valve 5 is pressed toward the compression side g of the air cylinder 2a. However, the pressure in the container body 1 increases so much that the check valve 4 cannot eject air. In this case, the valve body 5c is pushed toward the back side of the air piston 2b against the urging force of the spring 5b due to the pressure in the air cylinder 2a, whereby the valve body 5c is separated from the seating surface. 1 is opened, and the air passing through the path r is released to the atmosphere through the outside air introduction path as indicated by the arrow in the enlarged view of the main part of FIG. 1, and the container body 1 retains at least the initial external shape. The pressure is maintained at a necessary level.

また、６はエアシリンダー２ａの径方向内側で同心二重配置となるように設けられた液用ポンプである。この液用ポンプ６は、内容物を吸い込むための吸い込み口ｈを有し、吸い込みにかかる内容物の排出経路を形成する液用シリンダー６ａ（エアポンプ２のエアシリンダー２ａと一体に成形されている）と、この液用シリンダ−６ａでエアピストン２ｂと同期して排出経路を開閉する液用開閉弁６ｂと、この液用開閉弁６ｂの上部において連係する中空ステム６ｃとから構成されている。   Reference numeral 6 denotes a liquid pump provided so as to have a concentric double arrangement inside the air cylinder 2a in the radial direction. The liquid pump 6 has a suction port h for sucking the contents, and forms a discharge path for the contents to be sucked (molded integrally with the air cylinder 2a of the air pump 2). And a liquid on-off valve 6b that opens and closes the discharge path in synchronism with the air piston 2b by the liquid cylinder 6a, and a hollow stem 6c that is linked at an upper portion of the liquid on-off valve 6b.

液用ポンプ６の液用開閉弁６ｂは、液用シリンダー６ａの内壁に沿ってスライド可能な中空円筒状のピストン６ｂ１と、このピストン６ｂ１の開口を通り抜けて中空ステム６ｃの内面に形成された複数の縦リブ６ｃ１等によって固定保持される弁体６ｂ２と、この弁体６ｂ２を液用シリンダー６ａ内で弾性支持するスプリング６ｂ３からなっている。 Liquid-off valve 6b of the liquid pump 6, a piston 6b 1 slidable hollow cylindrical shape along the inner wall of the liquid cylinder 6a, is formed on the inner surface of the hollow stem 6c through an opening of the piston 6b 1 The valve body 6b 2 is fixedly held by a plurality of vertical ribs 6c 1 and the like, and the spring 6b 3 elastically supports the valve body 6b 2 in the liquid cylinder 6a.

７は中空ステム６ｃにつながり、液用開閉弁６ｂの開放によって容器本体１内の内容物を、中空ステム６ｃを通して内容物を噴出させるノズルヘッドである。   A nozzle head 7 is connected to the hollow stem 6c and ejects the contents in the container body 1 through the hollow stem 6c by opening the liquid on-off valve 6b.

ノズルヘッド７はその外周壁にノズル７ａが設けられており、該ノズルヘッド７の押し込みと復帰操作を繰り返すことによってエアポンプ２及び液用ポンプ６を作動させるものであって、これによって充填空間Ｍ内の内容物を外界へと噴出させるとともに容器本体１内にエアを吹き込んで容器の外観形状を初期形状に保持する。   The nozzle head 7 is provided with a nozzle 7 a on the outer peripheral wall thereof, and the air pump 2 and the liquid pump 6 are operated by repeatedly pushing and returning the nozzle head 7. And the air is blown into the container main body 1 to keep the outer shape of the container at the initial shape.

８は中空ステム６ｃの噴出経路内に配置されたボールタイプの弁体（逆止弁）、９は液用ポンプ６の吸引口ｈにつながり容器本体１の底部へ向けて伸延する吸引管である。   8 is a ball-type valve element (check valve) disposed in the ejection path of the hollow stem 6c, and 9 is a suction pipe connected to the suction port h of the liquid pump 6 and extending toward the bottom of the container body 1. .

吸引管９はその下端に容器本体１の底部に当接させて周壁部分に内容物を流入させる切欠部９ａを形成しておくことができ、切欠部９ａを設けた場合にはその切欠部９ａから内容物を流入させることか可能となるため吸引管９の下端を容器本体１の底部に接触させて容器本体１の柱として機能させることができる。   The suction pipe 9 can be formed at its lower end with a notch 9a that abuts the bottom of the container body 1 and allows the contents to flow into the peripheral wall portion. When the notch 9a is provided, the notch 9a is provided. Therefore, the lower end of the suction pipe 9 can be brought into contact with the bottom of the container body 1 to function as a column of the container body 1.

１０は液用ポンプ６をエアポンプ２とともに容器本体１の口部１ａに固定保持するベースキャップである。ベースキャップ１０は容器本体１の口部１ａの外側壁に係合するねじ部を有する周壁１０ａと、この周壁１０ａの上端に一体連結して下向きに開放された空間領域を形成する天壁１０ｂと、この天壁１０ｂの中央部にて起立してノズルヘッド７の基体（中空ステム６ｃに嵌合する縦筒）を挿通させるガイド筒１０ｃとから構成されており、天壁１０の裏面と、容器本体１の口部１ａの先端面との間にエアポンプ２のエアシリンダー２ａ上端フランジ部を挟み込むことによりエアポンプ２を液用ポンプ６とともに固定保持するようになっている。   Reference numeral 10 denotes a base cap for fixing and holding the liquid pump 6 together with the air pump 2 to the mouth portion 1 a of the container body 1. The base cap 10 has a peripheral wall 10a having a threaded portion that engages with the outer wall of the mouth 1a of the container body 1, and a ceiling wall 10b that is integrally connected to the upper end of the peripheral wall 10a to form a downwardly open space region. And a guide cylinder 10c that stands up at the center of the top wall 10b and allows the base of the nozzle head 7 (a vertical cylinder fitted to the hollow stem 6c) to pass therethrough. The air pump 2 is fixedly held together with the liquid pump 6 by sandwiching the upper end flange portion of the air cylinder 2a of the air pump 2 between the front end surface of the mouth portion 1a of the main body 1.

さらに、１１は弁体６ｂ２の周壁に設けられ内容物を通過させる貫通孔、１２は弁体６ｂ２の周壁の外表面に設けられた縦リブである。貫通孔１１は弁体６ｂ２の周りの対向位置に２つ設けられ、この貫通孔１１の間には縦リブ１２を片側につき３つ形成したものを例として示してある（図３（ｂ）参照）。 Further, 11 is a through hole provided in the peripheral wall of the valve body 6b 2 and allows the contents to pass through, and 12 is a vertical rib provided on the outer surface of the peripheral wall of the valve body 6b 2 . Two through holes 11 are provided at opposite positions around the valve body 6b 2 and three vertical ribs 12 are formed between the through holes 11 on one side as an example (FIG. 3B). reference).

ノズルヘッド７を最も押し込んだ図２に示すような状態において押し込みにかかる力を取り除くと、液用ポンプ６のスプリング６ｂ３の付勢力によって中空ステム６ｃは押上げられ、エアピストン２ｂは上方へと移動し図１に示したような初期姿勢へと復帰し、液用開閉弁６ｂは図３（ａ）（ｂ）に示すような状態になる一方、エアポンプ２では、ベースキャップ１０のガイド筒１０ｃと、ノズルヘッド７の基体との相互間に形成された隙間（図示せず）及び外気導入弁３を通してエアシリンダー２ａ内にエアが導入される。 Upon removal of the force to push in the state shown in FIG. 2 most pushed it a nozzle head 7, hollow stem 6c is pushed up by the urging force of the spring 6b 3 of the liquid pump 6, air piston 2b is upward 1, the liquid on-off valve 6b is in the state shown in FIGS. 3 (a) and 3 (b). On the other hand, in the air pump 2, the guide cylinder 10c of the base cap 10 is moved. Then, air is introduced into the air cylinder 2 a through a gap (not shown) formed between the nozzle head 7 and the base body and the outside air introduction valve 3.

ノズルヘッド７を再び押し込むと、液用シリンダー６ａ内の液用開閉弁６ｂは図４に示すように開放され、内容物は中空ステム６ｃの噴出経路を経てノズルヘッド７のノズル７ａから外界へと噴出し、エアシリンダー２ａ内のエアは加圧、圧縮されて逆止弁４を通して容器本体１内へ噴出される。容器本体１内にエアが供給される結果、該容器本体１は常時初期形状に保持されることとなり薄肉容器であっても内容物を使い切るまで自立性が確保されるとともに外観形状が安定的に維持される。   When the nozzle head 7 is pushed in again, the liquid on-off valve 6b in the liquid cylinder 6a is opened as shown in FIG. 4, and the content passes from the nozzle 7a of the nozzle head 7 to the outside through the ejection path of the hollow stem 6c. The air in the air cylinder 2 a is pressurized and compressed, and is jetted into the container body 1 through the check valve 4. As a result of supplying air into the container main body 1, the container main body 1 is always held in the initial shape, and even if it is a thin-walled container, self-sustainability is ensured until the contents are used up and the external shape is stable. Maintained.

容器本体１内の圧力がエアシリンダー２ａ内の圧力よりも高くなった場合においては、逆止弁４が開放されず容器本体１内へエアを噴出させることができなくなるが、この時、エアシリンダー２ａ内のエアは圧力開放弁５を通してエアピストン２ｂの背面側を通り容器の外側へと放出され、容器本体１内の圧力はほぼ一定に保たれる。   When the pressure in the container body 1 is higher than the pressure in the air cylinder 2a, the check valve 4 is not opened and air cannot be ejected into the container body 1, but at this time, the air cylinder The air in 2a is discharged through the pressure release valve 5 to the outside of the container through the back side of the air piston 2b, and the pressure in the container body 1 is kept substantially constant.

上記の構成になるポンプ付き薄肉容器は、充填空間Ｍ内にエアを導入し該充填空間Ｍの圧力を高めることにより容器本体１の外観形状の維持と内容物の吐出を可能にした構成例として示したが、液用シリンダー６ａの内側下端に弁体（逆止弁）を別途に配置し、液用シリンダー６ａ内に吸引された内容物を加圧、圧縮して外部へ吐出させる従来型の液用ポンプを適用することも可能であり、この場合も容器本体１の外観形状が損なわれることはない。   The thin-walled container with a pump having the above-described configuration is a configuration example in which the appearance of the container body 1 can be maintained and the contents can be discharged by introducing air into the filling space M and increasing the pressure in the filling space M. As shown, a valve body (check valve) is separately arranged at the inner lower end of the liquid cylinder 6a, and the contents sucked into the liquid cylinder 6a are pressurized, compressed and discharged to the outside. It is also possible to apply a liquid pump, and in this case, the external shape of the container body 1 is not impaired.

本発明にしたがうポンプ付きの薄肉容器は、容器本体１を構成する原料（合成樹脂）の使用量が少なくてすみゴミの減量に有効であり、廃棄に際しては小さくまとめることができるのでかさばることもない利点がある。   The thin-walled container with a pump according to the present invention is effective in reducing the amount of waste by using less raw material (synthetic resin) constituting the container body 1 and can be collected in a small amount when discarded. There are advantages.

資源の有効利用、ゴミの減量化が可能で、容器本体の外観形状の安定的化されたポンプ付き薄肉容器が提供できる。   It is possible to provide a thin-walled container with a pump that can effectively use resources, reduce the amount of garbage, and stabilize the external shape of the container body.
