Abstract

<P>PROBLEM TO BE SOLVED: To provide a pump for a container which can be assembled with the container for easily refilling contents. <P>SOLUTION: The pump for the container is constituted of a mounting cap for fixing the pump to a mouth; a mounting port opened downward of the mounting cap; a suction pipe; and a holder having an annular engaging ring detachably attached to the internal surface of the mounting cap to be fitted and assembled with the upper rim of the opening of the mouth so that it can tightly shift, and a rib having a connection tube extending from the engaging ring inwardly in the ring for holding the upper end of the suction pipe, also communicating with the suction pipe and detachably coupled with the mounting port. Thus the pump can be divided from the suction pipe and can be removed from a container body with the suction pipe left in the container body. Therefore, the contents do not drip from the removed pump, and there is no difficulty in finding where to place the pump. In addition, since the suction pipe is connected with the pump before using the pump, necessary components are not dispersed, resulting in no shortage in the components when in use. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【０００１】
【発明の属する技術分野】
本発明は、容器に取り付け容器内から内容物を吐出させる容器用ポンプ体に関し、特に内容物の詰め替えが容易な容器用ポンプ体に関する。
【０００２】
【従来の技術】
容器用ポンプ体を容器の口部に備え、ポンプ体を作動させて内容物を容器から吐出させるようにしたポンプ付き容器では、内容物を使い切ったとき内容物を充填した新たな容器に容器用ポンプ体をつけ替える方式があるが、簡易な包装材で包装された内容物を元の容器に注入して使用する方式の方が、ポンプ機構と元の容器をともに再利用できる点から経済的である。
ところが、ポンプ機構は内容物を容器内部から吸上げるための吸引パイプが容器内の底部まで通常延びており、詰め替えの際にポンプ機構を容器から取り外すと、内容物で濡れた吸引パイプが容器から引き出され、その状態で容器の口部から内容物を注入することとなるため、吸引パイプについた内容物が滴下したり、近くにポンプ機構を置いたときには内容物が付着したりして詰め替え作業がしにくかった。
【０００３】
一方容器の口部とポンプ機構との間を屈曲開閉自在に構成し、詰め替え作業の際にはポンプ機構を容器の口部で屈曲させ、開口された口部から内容物を注入したり（例えば特許文献１参照。）、あるいは容器から外したポンプ機構を容器から完全に引き出さず、予め形成したフックなどを用いて容器の口部にポンプ機構を掛け、その状態で内容物を開口された口部から注入するなどした発明が知られている。（例えば特許文献２参照。）。

【発明が解決しようとする課題】
しかしながら、ポンプ機構を容器の口部で開閉自在に構成したものは、開放した場合でもポンプ機構が容器口部に残ることや、容器に固定したときの取付強度を充分確保するため取付部が大きく、また構造が複雑になる点など簡便性等の点で課題があった。
【０００７】
また容器口部から外したポンプ機構をフック等により容器の口部の縁に掛ける方法は、ポンプ機構から延びる吸引パイプが容器の口部内に残ることから口部の開口面積が狭くなり、またポンプ機構が口部に引っ掛けられた状態であるので詰替用の容器から口部への内容物の注入がしにくいという問題があった。
【０００８】
本発明は、容器の口部に取り付けて使用する容器用ポンプ体において、内容物の詰め替えのとき液たれなどを起こして周囲を汚したりせず、内容物の詰め替えが容易な容器用ポンプ体を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明では、上記課題を解決するため次のように容器用ポンプ体を構成した。
【００１０】
請求項１に記載の発明は、容器本体の上部口部に取り付けられ、該容器本体に収容された内容物を該容器本体外へ吐出させる容器用ポンプ体であって、前記内容物を前記容器本体内から吐出するポンプ機構と、前記容器用ポンプ体を前記口部に脱着可能に組み付ける取付キャップと、前記ポンプ機構内に連通し、前記取付キャップ内に下方に向けて開口した取付口と、上端が前記取付口に脱着可能に嵌合し、下端が前記容器本体内に位置する吸引パイプと、前記吸引パイプを保持し、かつ前記口部からの前記内容物注入を可能にした状態で、該口部開口端部に密に組み付けられる保持具と、から容器用ポンプ体を構成した。
【００１１】
これにより、容器本体から容器用ポンプ体を取り外すと吸引パイプと容器用ポンプ体とが分割し、吸引パイプを容器本体内に残して容器用ポンプ体を容器本体から外すことができるので、外した容器用ポンプ体から内容物が滴下することはなく、また容器用ポンプ体の置き場所に困ることがない。
請求項２に記載の発明は、請求項１に記載の発明において、保持具は、取付キャップに脱着可能に取り付けられ、口部の開口端部に密に組み付き前記取付キャップから前記口部に移行される係合部材と、前記係合部材から延設され、前記吸引パイプを保持するリブとから形成した。
これにより、容器用ポンプ体を使用する前は、容器用ポンプ体に吸引パイプが取り付けられており、必要な構成部品が分散されず、使用時に部品不足を発生させない。
【００１２】
請求項３に記載の発明は、請求項２に記載の発明において、係合環は、上部が縮径された口部上端の縮径部に嵌め合わされ、かつ該縮径部に係止される係止部を備えた。これによれば、保持具を口部に確実に固定でき、しかも係合環が口部外方に突出しないため取付キャップの取り付けに支障をきたさない。
【００１３】
請求項４に記載の発明は、請求項２また３に記載の発明において、リブに、吸引パイプの上端を連結し、かつ該吸引パイプに連通させて取付口に脱着可能に連結される接続管を設けて構成した。これにより、吸引パイプを確実に保持でき、しかも取付口と吸引パイプとの接続及び取り外しが確実に行える。
【００１４】
請求項５に記載の発明は、請求項１〜４のいずれか１項に記載の発明において、容器用ポンプ体が組み付けられる容器本体が、該容器本体の壁体が内外二層の構造で内容物の減少に伴って内層内容量が減少するデラミボトルであり、吸引パイプを、該吸引パイプの下端が前記容器本体の口部下端より下部に位置する長さとした。
【００１５】
請求項６に記載の発明は、請求項１〜４のいずれか１項に記載の発明において、容器用ポンプ体が組み付けられる容器本体が、該容器本体の壁体を一重とした容器であり、吸引パイプを、該吸引パイプの下端が前記容器本体の底部まで達する長さとした。
【００１６】
これら発明により、吸引パイプを通して容器本体内の内容物を吸引し、内容物を最後まで吐出させることができる。
【００１７】
【発明の実施の形態】
以下、本発明にかかる容器用ポンプ体の一実施形態を、図面を参照しながら説明する。
【００１８】
図１に、ポンプ機構付き容器１の全体を示す。ポンプ機構付き容器１は、内容物を収納する容器本体２と容器本体２の上部にネジ込み式で取り付けられた容器用ポンプ体４（以下、ポンプ体４とする。）とからなっている。
【００１９】
容器本体２は、上部が口部６となっており、口部６の外周は図３に示すように突条７を螺旋状に形成してなる雄ネジ部８となっている。更に雄ネジ部８の上端は、雄ネジ部８の外径より径を細くした縮径部としての嵌合縁９となっている。また嵌合縁９の外周面には外周方向に向けて突出した係止部としての突条１０が周状に形成してある。
【００２０】
ポンプ体４は、図１の上部左側に吐出口４０を備え、下部に握りレバー４２を有し、握りレバー４２に連結したポンプ機構（図示せず。）を内部に有している。またポンプ体４の下部には吸引パイプ１２が容器本体２内に延び、ポンプ体４と容器本体２の間にパッキン１４が設けられている。ポンプ機構等、ポンプ体４の吐出機構については、通常の従来構造と同様であるので説明は省略する。また、本発明の容器用ポンプ体は、かかるレバー式のポンプ機構を有するものに限るものではない。
【００２１】
図２に、ポンプ体４の一部内部構造を示す。ポンプ体４は、ポンプ機構に通じる通路１５がほぼ中央に上下方向に設けられている。通路１５の下部は屈曲して取付口１６に連結し、取付口１６には吸引パイプ１２に連通した接続管２１が着脱自在に嵌め合わされている。吸引パイプ１２は、下端が容器本体２の内部の底まで到達しており、上端が保持具１７に保持されている。
【００２２】
取付キャップ２３はポンプ体４の下部に回動自在に取り付けられており、内面上部に、前述した保持具１７が脱着可能に取り付けてあり、またその下部に口部６の雄ネジ部８に螺合する雌ネジ部２４が形成してある。
【００２３】
保持具１７は、口部６の嵌合縁９に嵌合する円環状の係合環２２を有し、係合環２２から３つのリブ１９が係合環２２の中心に向けて取り付けられている。各リブ１９の先端は係合環２２の中心で一体となり、中心部分に吸引パイプ１２の上端が取り付けてある。更にリブ１９は、吸引パイプ１２に連通した接続管２１を上方に向けて支持しており、接続管２１は、上述したように取付口１６に脱着可能に連結している。
【００２４】
係合環２２は、口部６の内面に接する内壁２６の上端に外方向に延びる上壁２７が連続して設けられ、更に上壁２７の外端に外壁２８が下方に向けて折り返されており、外壁２８の内側には嵌合縁９に形成された突条１０に嵌る溝部２５が周状に形成してある。これにより保持具１７は当初取付キャップ２３の内面に取り付けられているが、保持具１７を口部６に取り付けると口部６に移行し、それ以降口部６に嵌合固定される。
【００２５】
尚、予め容器本体２内に保持具１７を用いて吸引パイプ１２等を取り付けておいてもよい。その場合、ポンプ体４には吸引パイプ１２等を接続させておく必要がなくなるが、パイプが固定された従来構造のポンプ機構を容器本体２に取り付けるときは、保持具１７等を口部から取り外す必要が生じる。
【００２６】
次に、ポンプ体４を用いたポンプ機構付き容器１の使用方法について説明する。
【００２７】
使用前は、ポンプ体４と容器本体２とはそれぞれ個別に用意されており、容器本体２には、洗剤等液状の内容物が充填され、口部６には封止用の栓（図示せず。）がネジ止めにより取り付けられている。
【００２８】
ポンプ体４を容器本体２に取り付けポンプ体４を用いて内容物を吐出させるときは、まず容器本体２から口部６を閉じている栓を外し、開口した口部６にポンプ体４の吸引パイプ１２の先端を差し入れ、取付キャップ２３を口部６にネジ止めする。取付キャップ２３を口部６の奥までネジ止めすると、図１に示すように保持具１７の径合環２２が口部６の嵌合縁９に嵌合する。
【００２９】
これにより、ポンプ体４と容器本体２とは固定され、握りレバー４２に指を掛けて手前に握るとポンプ機構が作動し、容器本体２内に収容されている内容物が吸引パイプ１２を通して吸引され、吐出口４０から吐出される。
【００３０】
そして、容器本体２内の内容物を使い切ったときは、内容物を収容した詰め替え用の補充用ボトル等を用意し、取付キャップ２３を回転させてポンプ体４を口部６から外す。ポンプ体４は、取付キャップ２３とともに口部６から外れるが、保持具１７の係合環２２が口部６の嵌合縁９に密に嵌合組み付けして固定されており、かつ取付口と接続管２１との間の連結が外れるため、図３に示すように保持具１７は口部６に移行嵌合したまま容器本体２に残る。
【００３１】
したがって、ポンプ体４は、吸引パイプ１２と保持具１７を容器本体２に残して容器本体２から取り外される。吸引パイプ１２と保持具１７が外されたポンプ体４は、内容物で濡れた部材が容器本体２にあることから持ち上げても液たれすることがなく、かつ取付キャップ２３を下にして置いたり、あるいは横にして置いた場合でも置いた箇所が内容物で濡れることがない。
【００３２】
容器本体２の口部６は、保持具１７が内側に嵌められた状態で開口し、図４に示すように内容物補充用の補充用ボトル４３から内容物を容器本体２内に注入する。保持具１７は内部にリブ１９が設けられているだけであるので、開口面積は保持具１７がない状態の口部６の開口面積とほとんど変わりがなく、また口部６の開口面より容器本体２の内部奥にリブ１９が設けられていることから、補充用ボトル４３から内容物を容器本体２内へ注入するに際して支障をきたすことがない。
【００３３】
補充用ボトル４３から内容物を容器本体２内に注入したなら、ポンプ体４を取り付ける。ポンプ体４の取り付けは、接続管２１を取付口１６に嵌め合わせ、その後、取付キャップ２３を口部６に締め付ける。すると吸引パイプ１２は接続管２１を介してポンプ体４のポンプ機構と連通する。
【００３４】
そして、握りレバー４２を握ると再びポンプ機構が作動し、吐出口４０から内物物が吐出される。吐出した後握りレバー４２を戻すと、負圧により吸引パイプ１２内を通して内容物がポンプ機構内に吸引される。その後握りレバー４２が再び握られるとポンプ機構内の内容物が押圧されて吐出口４０から吐出される。
【００３５】
このように本実施形態のポンプ体４によれば、内容物を詰め替えるためにポンプ体４を容器本体２から外しても、内容物に濡れた吸引パイプ１２等は容器本体２内に残ることから、内容物で周囲を濡らすことがなく、しかも口部６からポンプ体４が完全に外され口部６の周縁に邪魔になるものがなく、しかも口部６の開口面積が狭くならないため内容物の注入が容易にできる。
【００３６】
尚、上記実施形態では容器外壁が一重の容器本体２を例に説明したが、図５に示すように、いわゆるデラミボトルを容器本体５１として用いてもよい。
容器本体５１は、容器壁体５２が内層体５３と外層体５４の二重構造で内容物の減少に伴って内層体５３内の容量が減少する容器である。更にポンプ体も上記例に限るものではなく、容器本体５１に組み付けられるポンプ体５０は図５に示すように、頭部６５を上下方向に作動させて容器本体５１内から内容物を吐出させる方式のポンプ体５０である。
容器本体５１の口部５６には、外周に取付キャップ５７が螺着し、内周にはリブ５９を有する保持具６０が取り付けられている。保持具６０は、上述した保持具１７と同様の構成であり、係合環６３から延びるリブ５９に吸引パイプ６２が取り付けてあり、係合環６３が口部５６の嵌合縁６４に移行可能に密に組み付けられている。
またこの場合、容器本体５１がデラミボトルであることから、吸引パイプ６２は容器本体５１の底部まで延設せず、吸引パイプ６２の下端は容器中程に位置している。すなわち、内層体５３内に内容物が収容され内容物の吐出に伴って容器本体５１内で内層体５３内の体積が縮小するため、吸引パイプ６２の下端が容器中程に位置していても内容物を最後まで吐出させることができる。
更に、ポンプ体５０を口部５６から外した場合、保持具６０は口部５６に密に組み付けられているため口部５６に移行し、吸引パイプ６２とともに口部５６に取り付けられたままポンプ体５０が外されるため、内容物が落下したり、周囲を汚すことがない。
尚、係合環２２、６３を口部６、５６に上方から嵌め合わせるように形成したが、係合環２２等の形状はこれに限るものではなく、口部６の内部に形成された段部に係合したり、また口部６等の内部に係合させる場合は全体の形状が環状でなくともよい。
【００３７】
【発明の効果】
本発明の容器用ポンプ体によれば、次のような効果を有する。
【００３８】
請求項１に記載の発明は、容器本体の上部口部に取り付けられ、該容器本体に収容された内容物を該容器本体外へ吐出させる容器用ポンプ体であって、前記内容物を前記容器本体内から吐出するポンプ機構と、前記容器用ポンプ体を前記口部に脱着可能に組み付ける取付キャップと、前記ポンプ機構内に連通し、前記取付キャップ内に下方に向けて開口した取付口と、上端が前記取付口に脱着可能に嵌合し、下端が前記容器本体内に位置する吸引パイプと、前記吸引パイプを保持し、かつ前記口部からの前記内容物注入を可能にした状態で、該口部開口端部に密に組み付けられる保持具と、から容器用ポンプ体を構成した。
これにより、容器本体から容器用ポンプ体を取り外すと吸引パイプと容器用ポンプ体とが分割され、吸引パイプを容器本体内に残して容器用ポンプ体が容器本体から外されるので、外した容器用ポンプ体から内容物が滴下することがなく、また容器用ポンプ体の置き場所に困ることがない。
請求項２に記載の発明は、請求項１に記載の発明において、保持具は、取付キャップに脱着可能に取り付けられ、口部の開口端部に密に組み付き前記取付キャップから前記口部に移行される係合部材と、前記係合部材から延設され、前記吸引パイプを保持するリブとから形成した。
これにより、容器用ポンプ体を使用する前は、容器用ポンプ体に吸引パイプが取り付けられており、必要な構成部品が分散されず、使用時に部品不足を発生させない。
請求項３に記載の発明は、請求項２に記載の発明において、係合環は、上部が縮径された口部上端の縮径部に嵌め合わされ、かつ該縮径部に係止される係止部を備えた。これによれば、保持具を口部に確実に固定でき、しかも係合環が口部外方に突出しないため取付キャップの取り付けに支障をきたさない。
請求項４に記載の発明は、請求項２また３に記載の発明において、リブに、吸引パイプの上端を連結し、かつ該吸引パイプに連通させて取付口に脱着可能に連結される接続管を設けて構成した。これにより、吸引パイプを確実に保持でき、しかも取付口と吸引パイプとの接続及び取り外しが確実に行える。
請求項５に記載の発明は、請求項１〜４のいずれか１項に記載の発明において、容器用ポンプ体が組み付けられる容器本体が、該容器本体の壁体が内外二層の構造で内容物の減少に伴って内層内容量が減少するデラミボトルであり、吸引パイプを、該吸引パイプの下端が前記容器本体の口部下端より下部に位置する長さとした。
請求項６に記載の発明は、請求項１〜４のいずれか１項に記載の発明において、容器用ポンプ体が組み付けられる容器本体が、該容器本体の壁体を一重とした容器であり、吸引パイプを、該吸引パイプの下端が前記容器本体の底部まで達する長さとした。
これら請求項５及び請求項６によれば、吸引パイプを通して容器本体内の内容物を吸引し、容器本体内から内容物を最後まで吐出させることができる。

[0002]
[Prior art]
A container with a pump that has a pump body for the container at the mouth of the container and operates the pump body to discharge the contents from the container.When the contents are used up, a new container filled with the contents is used for the container. There is a method of replacing the pump body, but the method of injecting the contents packaged with simple packaging material into the original container and using it is more economical because both the pump mechanism and the original container can be reused. It is.
However, in the pump mechanism, a suction pipe for sucking the contents from the inside of the container usually extends to the bottom of the container, and when the pump mechanism is removed from the container at the time of refilling, the suction pipe wet with the contents is discharged from the container. Since the contents are drawn out and the contents are injected from the mouth of the container in this state, the contents attached to the suction pipe may drop, or when the pump mechanism is placed nearby, the contents may adhere and refill. It was difficult.

I have. The tip of each rib 19 is integrated at the center of the engagement ring 22, and the upper end of the suction pipe 12 is attached to the center. Further, the rib 19 supports the connection pipe 21 communicating with the suction pipe 12 upward, and the connection pipe 21 is detachably connected to the mounting port 16 as described above.
[0024]
The engagement ring 22 is provided with an upper wall 27 extending outward in a continuous manner at an upper end of an inner wall 26 in contact with an inner surface of the mouth portion 6, and further, an outer wall 28 is folded downward at an outer end of the upper wall 27. In addition, a groove 25 that fits into the ridge 10 formed on the fitting edge 9 is formed on the inner side of the outer wall 28 in a circumferential shape. As a result, the holder 17 is initially attached to the inner surface of the mounting cap 23. However, when the holder 17 is attached to the mouth 6, the holder 17 shifts to the mouth 6, and thereafter is fitted and fixed to the mouth 6.
[0025]
Note that the suction pipe 12 and the like may be attached to the container body 2 in advance using the holder 17. In this case, it is not necessary to connect the suction pipe 12 or the like to the pump body 4. However, when attaching the pump mechanism having the conventional structure in which the pipe is fixed to the container body 2, the holder 17 and the like are removed from the mouth. Need arises.
[0026]
Next, a method of using the container 1 with a pump mechanism using the pump body 4 will be described.
[0027]
Before use, the pump body 4 and the container body 2 are separately prepared, the container body 2 is filled with a liquid content such as a detergent, and the mouth 6 is sealed with a sealing plug (not shown). ) Are attached by screws.
[0028]
When attaching the pump body 4 to the container body 2 and discharging the contents using the pump body 4, first remove the stopper that closes the mouth 6 from the container body 2, and suck the pump body 4 into the opened mouth 6. The tip of the pipe 12 is inserted, and the mounting cap 23 is screwed to the mouth 6. When the mounting cap 23 is screwed to the inside of the mouth 6, the diameter ring 22 of the holder 17 is fitted to the fitting edge 9 of the mouth 6 as shown in FIG. 1.
[0029]
As a result, the pump body 4 and the container body 2 are fixed. When the user puts his / her finger on the grip lever 42 and squeezes the pump body forward, the pump mechanism operates, and the contents contained in the container body 2 are sucked through the suction pipe 12. Is discharged from the discharge port 40.
[0030]
When the contents in the container body 2 are used up, a refill bottle or the like for refilling the contents is prepared, and the pump cap 4 is removed from the mouth 6 by rotating the mounting cap 23. The pump body 4 is detached from the mouth 6 together with the mounting cap 23, but the engagement ring 22 of the holder 17 is tightly fitted and assembled to the fitting edge 9 of the mouth 6 and fixed. Since the connection with the connection pipe 21 is disconnected, the holder 17 remains in the container body 2 while being shifted and fitted to the mouth 6 as shown in FIG.
[0031]
Therefore, the pump body 4 is removed from the container body 2 while leaving the suction pipe 12 and the holder 17 in the container body 2. The pump body 4 from which the suction pipe 12 and the holder 17 have been removed does not drip even when lifted because the member wetted with the contents is in the container body 2, and may be placed with the mounting cap 23 down. Even if it is placed on its side, it will not be wet with the contents.
[0032]
The mouth 6 of the container body 2 is opened in a state where the holder 17 is fitted inside, and as shown in FIG. 4, the contents are poured into the container body 2 from a replenishing bottle 43 for replenishing the contents. Since the holder 17 has only the ribs 19 provided inside, the opening area is almost the same as the opening area of the opening 6 without the holder 17, and the opening of the container 6 is larger than the opening surface of the opening 6. Since the ribs 19 are provided in the inner part of the container 2, there is no problem in injecting the contents from the refill bottle 43 into the container body 2.
[0033]
When the contents are injected into the container body 2 from the refill bottle 43, the pump body 4 is attached. To attach the pump body 4, the connection pipe 21 is fitted to the attachment port 16, and then the attachment cap 23 is fastened to the mouth 6. Then, the suction pipe 12 communicates with the pump mechanism of the pump body 4 via the connection pipe 21.
[0034]
Then, when the grip lever 42 is gripped, the pump mechanism operates again, and the internal substance is discharged from the discharge port 40. When the grip lever 42 is returned after discharging, the contents are sucked into the pump mechanism through the suction pipe 12 by the negative pressure. Thereafter, when the grip lever 42 is gripped again, the contents in the pump mechanism are pressed and discharged from the discharge port 40.
[0035]
As described above, according to the pump body 4 of the present embodiment, even if the pump body 4 is removed from the container body 2 to refill the contents, the suction pipe 12 wet with the contents remains in the container body 2. Since the pump body 4 is completely removed from the mouth 6 and there is nothing obstructing the periphery of the mouth 6, and the opening area of the mouth 6 is not reduced, the contents are not wetted. Can be easily injected.
[0036]
In the above embodiment, the container main body 2 having a single container outer wall has been described as an example, but a so-called delami bottle may be used as the container main body 51 as shown in FIG.
The container body 51 is a container in which the container wall 52 has a double structure of an inner layer body 53 and an outer layer body 54 and the capacity in the inner layer body 53 decreases as the content decreases. Further, the pump body is not limited to the above example, and the pump body 50 assembled to the container main body 51 may be configured to operate the head 65 in the vertical direction to discharge the contents from the container main body 51 as shown in FIG. Pump body 50.
An attachment cap 57 is screwed onto the outer periphery of the mouth 56 of the container body 51, and a holder 60 having a rib 59 is attached on the inner periphery. The holding tool 60 has the same configuration as the holding tool 17 described above, and a suction pipe 62 is attached to a rib 59 extending from the engagement ring 63, and the engagement ring 63 can move to a fitting edge 64 of the mouth 56. Is tightly assembled.
Further, in this case, since the container body 51 is a delami bottle, the suction pipe 62 does not extend to the bottom of the container body 51, and the lower end of the suction pipe 62 is located in the middle of the container. That is, since the contents are stored in the inner layer body 53 and the volume of the inner layer body 53 is reduced in the container body 51 as the contents are discharged, even if the lower end of the suction pipe 62 is located in the middle of the container. The contents can be discharged to the end.
Further, when the pump body 50 is detached from the mouth 56, the holder 60 moves to the mouth 56 because it is tightly assembled to the mouth 56, and the pump body 50 remains attached to the mouth 56 together with the suction pipe 62. Since the 50 is removed, the contents do not drop or stain the surroundings.
Although the engagement rings 22 and 63 are formed so as to be fitted to the mouth portions 6 and 56 from above, the shape of the engagement ring 22 and the like is not limited to this, and the step formed inside the mouth portion 6 is not limited thereto. In the case of engaging with a part or engaging with the inside of the mouth part 6 or the like, the whole shape may not be annular.
