The outer cylinder portion 16 formed by the outer cylinder member 19 has a protruding taper portion 21 that protrudes inward from the lower end of the outer cylinder member 19 at the same inclination as the bottom taper portion 20. The liquid passage hole 17 is opened and closed by the inner surface 16 a formed by the tapered portion 21.

本第1実施形態では、容器本体11は、可撓性及び酸素バリア性を有するシート材料からなるチューブ容器となっている。このようなシート材料としては、例えばアルミラミネート樹脂が好ましく用いられる。また容器本体11は、例えば内径が10〜50mm程度、高さ(長さ)が70〜200mm程度の大きさの、底部11bが閉塞された円筒形状に形成される。   In the first embodiment, the container body 11 is a tube container made of a sheet material having flexibility and oxygen barrier properties. As such a sheet material, for example, an aluminum laminate resin is preferably used. Moreover, the container main body 11 is formed in the cylindrical shape with which the bottom part 11b was obstruct | occluded whose magnitude | size is about 10-50 mm, for example, and a height (length) is about 70-200 mm.

容器本体11の口部11aに装着されるポンプ装置12は、ポリオレフィン樹脂等の合成樹脂を用いて形成される。ポンプ装置12は、同じくポリオレフィン樹脂等の合成樹脂を用いて形成される外筒部材19の内側に収納された状態に組み付けられており、例えば外筒部材19を口部11aの内面に融着接合することにより、外筒部材19と共に容器本体11の口部11aに装着される。ポンプ装置12は、計量室22を含む公知のポンプ機構を備えており、シリンダとして機能する内筒15、内筒15の内面に密着摺動する張出し摺接部24を備えるピストン23、内筒15の底部14に設けられた逆止弁13、ピストン23の下部に設けられた吐出弁25等からなる。   The pump device 12 attached to the mouth portion 11a of the container body 11 is formed using a synthetic resin such as a polyolefin resin. The pump device 12 is assembled in a state of being housed inside an outer cylinder member 19 which is also formed using a synthetic resin such as a polyolefin resin. For example, the outer cylinder member 19 is fusion bonded to the inner surface of the mouth portion 11a. By doing so, it is attached to the mouth part 11 a of the container body 11 together with the outer cylinder member 19. The pump device 12 includes a known pump mechanism including a measuring chamber 22, and includes an inner cylinder 15 that functions as a cylinder, a piston 23 that includes an overhanging sliding contact portion 24 that slides in close contact with the inner surface of the inner cylinder 15, and an inner cylinder 15. The check valve 13 is provided at the bottom portion 14, the discharge valve 25 is provided below the piston 23, and the like.

ポンプ付き容器10の使用時には、ピストン23の上端の吐出口23aに吐出ノズル26が装着され(図1参照)、この吐出ノズル26を介してピストン23をスプリング部材27の付勢力に抗して押圧操作する。これによって、ポンプ装置12の計量室22に導入されていた内容物は、図2(a)に示すように、張出し摺接部24と吐出弁25との間に形成された隙間、及びピストン23の軸筒部28の側面に形成された流出開口29を経て軸筒部28の内側の吐出路に流入し、吐出口23a及び吐出ノズル26を介して吐出されることになる。   When the container 10 with a pump is used, a discharge nozzle 26 is attached to the discharge port 23a at the upper end of the piston 23 (see FIG. 1), and the piston 23 is pressed against the biasing force of the spring member 27 through the discharge nozzle 26. Manipulate. As a result, the contents introduced into the metering chamber 22 of the pump device 12 are, as shown in FIG. 2A, the gap formed between the overhanging sliding contact portion 24 and the discharge valve 25, and the piston 23. It flows into the discharge path inside the shaft tube portion 28 through the outflow opening 29 formed on the side surface of the shaft tube portion 28, and is discharged through the discharge port 23 a and the discharge nozzle 26.

また、吐出ノズル26及びピストン23への押圧を解除すれば、スプリング部材27の付勢力によってピストン23及び吐出弁25が上昇し、張出し摺接部24と吐出弁25との間の隙間が閉塞されて、内容物の吐出が停止されることになる。またピストン23及び吐出弁25の上昇によって計量室22の内部が負圧になることにより、逆止弁13が開放されて、容器本体11から計量室22に内容物が導入されることになる。   Further, when the pressure on the discharge nozzle 26 and the piston 23 is released, the piston 23 and the discharge valve 25 are raised by the urging force of the spring member 27, and the gap between the overhanging slidable contact portion 24 and the discharge valve 25 is closed. Thus, the discharge of the contents is stopped. Further, when the piston 23 and the discharge valve 25 rise, the inside of the measuring chamber 22 becomes negative pressure, so that the check valve 13 is opened and the contents are introduced from the container body 11 into the measuring chamber 22.

そして、本第1実施形態のポンプ付き容器10は、口部11aに設けられた外筒部材19による外筒部16に対してポンプ装置12が上下にスライド移動可能に取り付けられていることにより、当該ポンプ装置12を介して容器本体11に内容物の補充や充填ができる。   And the container 10 with a pump of this 1st Embodiment is attached so that the pump apparatus 12 can be slid up and down with respect to the outer cylinder part 16 by the outer cylinder member 19 provided in the opening part 11a, The container body 11 can be replenished or filled with the content via the pump device 12.

すなわち、本第1実施形態では、ポンプ装置12の外殻部分を構成する内筒15は、外筒部材19の内周面に沿って案内されるようにして、外筒部材19に対して上下にスライド移動できる。このようなスライド操作は、図2(a),(b)に示すように、例えば外筒部材19の上端縁部から上方に突出するように延設させた内筒15の上端係止部15aを把持したり、当該上端係止部15aに形成した係止孔30に専用の係止具を係止して、内筒15を引き上げたり押し込むことによって、容易に行うことができる。   That is, in the first embodiment, the inner cylinder 15 that constitutes the outer shell portion of the pump device 12 is guided along the inner peripheral surface of the outer cylinder member 19 so as to move up and down with respect to the outer cylinder member 19. You can slide to. As shown in FIGS. 2A and 2B, such a sliding operation is performed by, for example, the upper end locking portion 15a of the inner cylinder 15 extended so as to protrude upward from the upper end edge of the outer cylinder member 19. Can be easily carried out by holding a dedicated locking tool in the locking hole 30 formed in the upper end locking portion 15a and pulling up or pushing in the inner cylinder 15.

また、本第1実施形態では、外筒部材19の上端部内側面には、凹凸段部となった位置決め被係合部31aが設けられていると共に、内筒15の上端部外側面には、凹凸段部となった位置決め係合部31bが設けられている。位置決め被係合部31aの凹凸段部に位置決め係合部31bの凹凸段部を選択的に係合することにより、通液孔17を閉塞した状態と通液孔17を開放した状態とを切換えて、これらの状態のまま保持できるようになっている。通液孔17は、図2(a)に示すように、内筒15を押し込んで底部テーパー部20を張り出しテーパー部21に密着させることにより、この張り出しテーパー部21による外筒部16の内面16aによって閉塞される。この通液孔17を閉塞した状態が、ポンプ付き容器10を使用する状態である。図2(b)に示すように、容器本体11に内容物を充填する際には、内筒15を引き上げて底部テーパー部20を張り出しテーパー部21から離間させることにより、通液孔17を開放する。   Further, in the first embodiment, a positioning engaged portion 31a that is an uneven step portion is provided on the inner surface of the upper end portion of the outer cylinder member 19, and the outer surface of the upper end portion of the inner tube 15 is A positioning engagement portion 31b that is an uneven step portion is provided. By selectively engaging the concavo-convex step portion of the positioning engagement portion 31b with the concavo-convex step portion of the positioning engaged portion 31a, the liquid passage hole 17 is switched between the closed state and the liquid passage hole 17 is opened. Thus, these states can be maintained. As shown in FIG. 2A, the liquid passage hole 17 is formed by pushing the inner cylinder 15 and bringing the bottom taper portion 20 into close contact with the overhanging taper portion 21, whereby the inner surface 16 a of the outer tube portion 16 formed by the overhanging taper portion 21. It is blocked by. The state where the liquid passage hole 17 is closed is a state where the pump-equipped container 10 is used. As shown in FIG. 2 (b), when the container body 11 is filled with the contents, the inner cylinder 15 is pulled up so that the bottom taper portion 20 is projected and separated from the taper portion 21 to open the liquid passage hole 17. To do.

上述の構成を備える本第1実施形態のポンプ付き容器10によれば、容器本体11の口部11aに装着されたポンプ装置12を介して、内容物を容器本体11に容易に充填することが可能になる。   According to the pump-equipped container 10 of the first embodiment having the above-described configuration, the container body 11 can be easily filled with the contents via the pump device 12 attached to the mouth portion 11a of the container body 11. It becomes possible.

すなわち、本第1実施形態によれば、外筒部16としての外筒部材19に対して内筒15を引き上げるように上方にスライド移動させれば、図2(b)に示すように、底部テーパー部20が張り出しテーパー部21から離間して、通液孔17が開放されると共に、底部テーパー部20と張り出しテーパー部21との間に容器本体11の内部への流路となる隙間が確保される。この状態でピストン23を押圧操作すれば、張出し摺接部24と吐出弁25とが離間して、吐出口23aから軸筒部28の内側の吐出路を経て流出開口29を通過し、さらに張出し摺接部24と吐出弁25との間の隙間及び通液孔17を通過し、底部テーパー部20と張り出しテーパー部21との間の隙間から容器本体11の内部に至る、逆止弁13を経ない充填流路Sが迂回流路として形成されることになる。   That is, according to the first embodiment, if the inner cylinder 15 is slid upward to pull up the outer cylinder member 19 as the outer cylinder part 16, the bottom part as shown in FIG. The taper portion 20 is separated from the overhanging taper portion 21 to open the liquid passage hole 17, and a gap is formed between the bottom taper portion 20 and the overhanging taper portion 21 as a flow path to the inside of the container body 11. Is done. If the piston 23 is pressed in this state, the overhanging slidable contact portion 24 and the discharge valve 25 are separated from each other, pass through the discharge opening inside the shaft tube portion 28 from the discharge port 23a, pass through the outflow opening 29, and further overhang. A check valve 13 that passes through the gap between the sliding contact portion 24 and the discharge valve 25 and the liquid passage hole 17 and reaches the inside of the container main body 11 through the gap between the bottom taper portion 20 and the protruding taper portion 21. A non-passing filling channel S is formed as a bypass channel.

したがって、迂回流路を形成した後に、例えば図3(a),(b)に示すように、充填用の内容物を収容した収容容器40の上端接続口部41に、吐出ノズル26を取り外したポンプ付き容器10を倒立させてこれの吐出口部32を接続した状態で、ポンプ付き容器10に押圧力を付与すれば、形成された充填流路Sを経て収容容器40から内容物が容器本体11にスムーズに流入してゆく。これによって、ポンプ装置12を装着したままで、内容物を容器本体11に容易に充填することが可能になる。   Therefore, after forming the detour channel, for example, as shown in FIGS. 3A and 3B, the discharge nozzle 26 is removed from the upper end connection port 41 of the storage container 40 that stores the contents for filling. If a pressing force is applied to the pump-equipped container 10 in a state where the pump-equipped container 10 is inverted and the discharge port portion 32 is connected, the contents are transferred from the storage container 40 through the formed filling channel S to the container body. 11 will flow smoothly. This makes it possible to easily fill the container body 11 with the contents while the pump device 12 is mounted.

図4(a),(b)に、本発明の好ましい第2実施形態に係るポンプ付き容器33の要部を示す。本第2実施形態のポンプ付き容器33は、上記第1実施形態のポンプ付き容器10と略同様の構成を備える他、内筒15には、これの上端部をコの字断面形状を有するように外側に折り返し延設させて、外筒部材19の上端部を挟み込むようにして係止される挟込み係止部34が形成されている。また、挟込み係止部34の下端内側縁部から内側に突出して下端係止リブ35が設けられており、挟込み係止部34の外周面には外側に突出して滑止めリブ36が設けられている。   The principal part of the container 33 with a pump which concerns on FIG. 4 (a), (b) based on preferable 2nd Embodiment of this invention is shown. The pump-equipped container 33 of the second embodiment has substantially the same configuration as the pump-equipped container 10 of the first embodiment, and the inner cylinder 15 has a U-shaped cross-sectional shape at the upper end thereof. A pinching locking portion 34 is formed that is folded outwardly and is locked so as to pinch the upper end portion of the outer cylinder member 19. Further, a lower end locking rib 35 is provided so as to protrude inward from an inner edge of the lower end of the sandwiching locking portion 34, and an antiskid rib 36 is provided on the outer peripheral surface of the sandwiching locking portion 34 so as to protrude outward. It has been.

一方、外筒部材19には、これの上部外周面から外側に突出して、容器本体11の口部11aの上端面に当接接合されると共に、内筒15を押し込んだ際に、内筒15の挟込み係止部34の下端面を当接させるストッパーリブ37が形成されている。また、外筒部材19の上端部外周面には、内筒15を引き上げた際に、挟込み係止部34の下端係止リブ35を係止させるストッパー段差部38が設けられている。   On the other hand, the outer cylinder member 19 protrudes outward from the upper outer peripheral surface of the outer cylinder member 19 and is in contact with and joined to the upper end surface of the mouth portion 11a of the container body 11, and when the inner cylinder 15 is pushed in, the inner cylinder 15 A stopper rib 37 is formed to contact the lower end surface of the sandwiching and locking portion 34. In addition, a stopper step portion 38 is provided on the outer peripheral surface of the upper end portion of the outer cylinder member 19 to lock the lower end locking rib 35 of the pinching locking portion 34 when the inner cylinder 15 is pulled up.

そして、本第2実施形態では、図4(a)に示すポンプ付き容器33を使用する際における、内筒15を押し込んで挟込み係止部34の下端面をストッパーリブ37に当接させて通液孔17を閉塞した状態と、図4(b)に示す容器本体11に内容物を充填する際における、内筒15を引き上げて挟込み係止部34の下端係止リブ35をストッパー段差部38に係止させて通液孔17を開放した状態とを、切換えることができる。   And in this 2nd Embodiment, when using the container 33 with a pump shown to Fig.4 (a), the inner cylinder 15 is pushed in and the lower end surface of the clamping latching | locking part 34 is made to contact | abut to the stopper rib 37. FIG. When the liquid passage hole 17 is closed and when the container main body 11 shown in FIG. 4B is filled with the contents, the inner cylinder 15 is pulled up to hold the lower end locking rib 35 of the holding locking portion 34 with a stopper step. It is possible to switch between the state in which the liquid passage hole 17 is opened by being engaged with the portion 38.

本第2実施形態のポンプ付き容器33によっても、上記第1実施形態のポンプ付き容器10と同様の作用効果が奏される他、例えば挟込み係止部34の外側から挟み込むようにして内筒15の上端部を容易に把持することが可能になり、内筒15を外筒部材19に対して上下にスライド移動させて、通液孔17が閉塞した状態と開放した状態とを切り替える操作を、さらにスムーズに行うことが可能になる。   The pump-equipped container 33 of the second embodiment also provides the same operational effects as the pump-equipped container 10 of the first embodiment, and, for example, an inner cylinder that is sandwiched from the outside of the sandwiching and locking portion 34. 15 can be easily gripped, and the inner cylinder 15 is slid up and down with respect to the outer cylinder member 19 to switch between the closed state and the opened state of the liquid passage hole 17. It becomes possible to perform even more smoothly.

なお、本発明は上記各実施形態に限定されることなく種々の変更が可能である。例えば、内筒をスライド移動させる外筒部は、容器本体の口部にスリーブ状の外筒部材を装着して形成する必要は必ずしも無く、容器本体の口部の内周面を補強する加工や、口部の内周面から張り出しテーパー部を設ける加工等を施して、容器本体の口部自体を外筒部として用いることもできる。   The present invention is not limited to the above-described embodiments, and various modifications can be made. For example, the outer cylinder part that slides the inner cylinder does not necessarily have to be formed by attaching a sleeve-shaped outer cylinder member to the mouth part of the container body, and the inner peripheral surface of the mouth part of the container body can be reinforced. The container body itself can be used as the outer cylinder part by applying a process such as providing a taper part protruding from the inner peripheral surface of the mouth part.

また、通液孔を内筒の底部周縁部分の底部テーパー部に設けて、張り出しテーパー部による外筒部の内面によって通液孔を開閉する必要は必ずしも無く、通液孔を逆止弁と離間した他の部分に設け、外筒部には張り出しテーパー部を設けることなく、その他の部分の内面によって通液孔を開閉することもできる。例えば、図5(a),(b)に示すように、通液孔17’を内筒15の底部14に近接する周壁部に横方向に貫通して設けると共に、外筒部16の内周面に、通液孔17’が形成された部分の周壁部と密着する密着段差部39を設け、この密着段差部39による内面16aによって通液孔17’を開閉することもできる。   In addition, it is not always necessary to provide a fluid passage hole in the bottom taper portion of the bottom peripheral edge of the inner cylinder, and the fluid passage hole is not necessarily opened and closed by the inner surface of the outer cylinder portion by the overhanging taper portion. The liquid passage hole can be opened and closed by the inner surface of the other part without providing the projecting taper part on the outer cylinder part. For example, as shown in FIGS. 5 (a) and 5 (b), a liquid passage hole 17 ′ is provided through the peripheral wall portion adjacent to the bottom portion 14 of the inner cylinder 15 in the lateral direction, and the inner periphery of the outer cylinder portion 16. It is also possible to provide a close contact step portion 39 in close contact with the peripheral wall portion of the portion where the liquid passage hole 17 ′ is formed on the surface, and the liquid passage hole 17 ′ can be opened and closed by the inner surface 16 a by the close contact step portion 39.

さらに、本発明のポンプ付き容器は、チューブ容器を容器本体とするポンプ付きチューブ容器である必要は必ずしも無く、ボトル容器等を容器本体とするポンプ付き容器など、その他の種々のポンプ付き容器でもよい。さらにまた、容器本体に収容される内容物は、酸素によって劣化する染毛剤でに限られず、流動性を有するその他の種々の内容物でもよい。   Furthermore, the pump-equipped container of the present invention does not necessarily have to be a tube container with a pump having a tube container as a container body, and may be other various containers with a pump such as a container with a pump having a bottle container or the like as a container body. . Furthermore, the contents accommodated in the container body are not limited to hair dyes that deteriorate due to oxygen, and may be other various contents having fluidity.
