The discharger 3 includes a main body 30 having a stem (not shown), a pressing head 31, and a suction pipe 32.

ここで、本実施形態では、容器本体2における横断面の中央を通る軸線を容器軸Oとし、以下では容器軸Oに沿って押下ヘッド31側を上側、吸い上げパイプ32側を下側とする。また、容器軸Oに沿う方向を上下方向、容器軸O方向から見た平面視において、容器軸Oに直交する方向を径方向、容器軸O回りに周回する方向を周方向とする。   Here, in the present embodiment, the axis passing through the center of the cross section of the container body 2 is the container axis O, and in the following, the pressing head 31 side is the upper side and the suction pipe 32 side is the lower side along the container axis O. In addition, the direction along the container axis O is the vertical direction, and in a plan view as viewed from the container axis O direction, the direction orthogonal to the container axis O is the radial direction, and the direction around the container axis O is the circumferential direction.

吐出器3の本体部30には、押下ヘッド31及び前記ステムに連係した空気用ピストン(図示省略)が内部に上下摺動自在に収容された空気用シリンダ33と、押下ヘッド31及び前記ステムに連係した液用ピストン(図示省略)が内部に上下摺動自在に収容された液用シリンダ34と、を備えている。液用シリンダ34の下端開口部の内側には、吸い上げパイプ32の上端が嵌合されている。吸い上げパイプ32の下端開口部32aは、容器本体2の底部22の内面上に開口する。   The main body 30 of the discharger 3 includes an air cylinder 33 in which a push-down head 31 and an air piston (not shown) linked to the stem are slidably housed inside, and the push-down head 31 and the stem. A liquid piston (not shown) that is linked is provided with a liquid cylinder 34 slidably accommodated therein. The upper end of the suction pipe 32 is fitted inside the lower end opening of the liquid cylinder 34. A lower end opening 32 a of the suction pipe 32 opens on the inner surface of the bottom 22 of the container body 2.

前記ステムは、空気用シリンダ33及び液用シリンダ34に対して上方付勢状態で下方移動可能に立設されている。装着キャップ35は、押下ヘッド31を挿通する挿通孔(図示省略)が形成された天壁部35aを有し、上側が小径筒35b、下側が大径筒35cとされた2段円筒状に形成された有頂筒状をなしている。大径筒35cには、容器本体2の口部21の雄ねじ部21aに螺合する雌ねじ部が形成されている。   The stem is erected so as to be movable downward in an upward biased state with respect to the air cylinder 33 and the liquid cylinder 34. The mounting cap 35 has a top wall portion 35a in which an insertion hole (not shown) for inserting the pressing head 31 is formed. The mounting cap 35 is formed in a two-stage cylindrical shape having a small diameter cylinder 35b on the upper side and a large diameter cylinder 35c on the lower side. It has a crested cylindrical shape. The large-diameter cylinder 35 c is formed with a female screw portion that is screwed into the male screw portion 21 a of the mouth portion 21 of the container body 2.

押下ヘッド31は、前記ステムの上端部に装着されている。押下ヘッド31は、径方向の外側に向けて突出する吐出筒36を備えている。吐出筒36内は、前記ステム内に連通している。押下ヘッド31及び前記ステムを一体に押し下げることで、前記ステムから吐出筒36内に内容物が供給され吐出される。   The pressing head 31 is attached to the upper end portion of the stem. The pressing head 31 includes a discharge cylinder 36 that protrudes outward in the radial direction. The inside of the discharge cylinder 36 communicates with the stem. By pressing the pressing head 31 and the stem together, the contents are supplied from the stem into the discharge cylinder 36 and discharged.

オーバーキャップ4は、有頂筒状に形成され、天壁部の外周縁から装着キャップ35の小径筒35bの外側に嵌合する嵌合筒41が下方に向けて延びている。   The overcap 4 is formed in a top tube shape, and a fitting tube 41 that fits outside the small diameter tube 35b of the mounting cap 35 extends downward from the outer peripheral edge of the top wall portion.

容器本体2は、内容物が充填される内容物収容部20と、この内容物収容部20を径方向の外側から囲繞し、かつ下端縁26aが容器本体2の底部22(窪み部23)より下方に位置する外筒26とにより二重筒状に形成されている。図示の例では、外筒26は内容物収容部20と一体に形成された下端開口の筒状とされている。
底部22の内面には、吸い上げパイプ32の下端部が、その外周面32bとの間に隙間を設けた状態で収容される窪み部23が形成されている。つまり、吸い上げパイプ32の下端部の外周面32bと窪み部23の内周面23cとの間には、隙間Sが設けられている。
図2に示すように、底部22の内面のうち、窪み部23を回避した部分は、窪み部23側に向かうに従い漸次、下方に向けて延在し窪み部23の開口周縁部23aに連なる傾斜面24とされている。
The container main body 2 surrounds the content storage portion 20 filled with the content, the content storage portion 20 from the outside in the radial direction, and the lower end edge 26a from the bottom portion 22 (the recessed portion 23) of the container main body 2. A double cylinder is formed by the outer cylinder 26 positioned below. In the illustrated example, the outer cylinder 26 has a cylindrical shape with a lower end opening formed integrally with the content container 20.
A recess 23 is formed on the inner surface of the bottom portion 22 so that the lower end portion of the suction pipe 32 is accommodated in a state where a gap is provided between the lower end portion and the outer peripheral surface 32b. That is, a gap S is provided between the outer peripheral surface 32 b at the lower end portion of the suction pipe 32 and the inner peripheral surface 23 c of the hollow portion 23.
As shown in FIG. 2, the portion of the inner surface of the bottom portion 22 that avoids the dent portion 23 extends gradually downward toward the dent portion 23 side and continues to the opening peripheral edge portion 23 a of the dent portion 23. The surface 24 is used.

窪み部23の底面23bには、図1及び図3に示すように、吸い上げパイプ32の下端開口部32aを、その内側と窪み部23内とを連通した状態で支持する支持突部25が配設されている。支持突部25は、平面視で十字状に形成され、吸い上げパイプ32の下端部を当接させた状態で支持している。   As shown in FIGS. 1 and 3, the bottom surface 23 b of the recess 23 is provided with a support protrusion 25 that supports the lower end opening 32 a of the suction pipe 32 in a state where the inside thereof and the interior of the recess 23 are communicated with each other. It is installed. The support protrusion 25 is formed in a cross shape in plan view, and supports the lower end portion of the suction pipe 32 in a contact state.

なお、吐出器3としては、例えば図1に示すようないわゆるポンプタイプの構成の他、エアゾールタイプ、スクイズタイプの構成などが挙げられる。
スクイズタイプとしては、容器本体の胴部を弾性変形可能に形成し、胴部をスクイズ変形することで、内容物を吸い上げパイプを通して吐出筒から吐出させるようにしてもよい。
Examples of the discharger 3 include an aerosol type and a squeeze type configuration in addition to a so-called pump type configuration as shown in FIG.
As the squeeze type, the body portion of the container body may be formed to be elastically deformable, and the body portion may be squeezed to cause the contents to be discharged from the discharge cylinder through the suction pipe.

以上説明した本実施形態による吐出容器1によれば、以下の作用効果を奏する。
図1に示すように、吐出容器1では、吸い上げパイプ32の下端部が窪み部23内に収容されている状態で、吸い上げパイプ32の下端開口部32aが支持突部25に支持されるので、吸い上げパイプ32の下端部の外周面32bと窪み部23の内周面23cとの間に隙間Sを設けるとともに、吸い上げパイプ32の下端開口部32a内と窪み部23内とを連通させた状態に確実に保持することができる。
そのため、吐出容器1において内容物を吐出させる際には、オーバーキャップ4を取り外し、吐出器3の押下ヘッド31を押し下げ操作すると、吸い上げパイプ32によって下端開口部32aから容器本体2の窪み部23内の内容物が吸い上げられ、ステムを通過して吐出筒36より吐出される。
According to the discharge container 1 by this embodiment demonstrated above, there exist the following effects.
As shown in FIG. 1, in the discharge container 1, the lower end opening 32 a of the suction pipe 32 is supported by the support protrusion 25 in a state where the lower end of the suction pipe 32 is accommodated in the recess 23. A clearance S is provided between the outer peripheral surface 32b of the lower end portion of the suction pipe 32 and the inner peripheral surface 23c of the recess portion 23, and the inside of the lower end opening portion 32a of the suction pipe 32 and the interior of the recess portion 23 are communicated with each other. It can be held securely.
Therefore, when discharging the contents in the discharge container 1, if the overcap 4 is removed and the pressing head 31 of the discharger 3 is pushed down, the suction pipe 32 causes the suction pipe 32 to bring the inside of the recess 23 of the container main body 2. The contents are sucked up, passed through the stem, and discharged from the discharge cylinder 36.

このように、本実施形態の吐出容器1では、底部22の内面のうち窪み部23の外周側に傾斜面24が形成されていることから、容器本体2内の内容物が残り少なくなったときに、窪み部23に集まりやすくなることに相俟って、この容器本体2内の内容物を残量少なく確実に吐出することができる。   Thus, in the discharge container 1 of this embodiment, since the inclined surface 24 is formed in the outer peripheral side of the hollow part 23 among the inner surfaces of the bottom part 22, when the content in the container main body 2 decreases. Combined with the fact that it tends to gather in the recess 23, the contents in the container body 2 can be reliably discharged with a small remaining amount.

また、本実施の形態では、内容物収容部20が外筒26によって径方向の外側から囲繞され、かつ外筒26の下端縁26aが窪み部23より下方に位置するように設けられているので、吐出容器1の外観に影響を与えることなく、上下方向の高さ寸法を一定に保ったまま、例えば内容物収容部20の上下方向の高さ寸法を変更してその内容量を変更することができる。   In the present embodiment, the content container 20 is surrounded by the outer cylinder 26 from the outside in the radial direction, and the lower end edge 26 a of the outer cylinder 26 is located below the recess 23. Without changing the appearance of the discharge container 1, for example, by changing the height of the content container 20 by changing the height of the content container 20 while keeping the vertical height constant. Can do.

また、本実施形態では、容器本体2の底部22の傾斜面24は、径方向の中央に向けて漸次、傾斜しているので、吸い上げパイプ32の下端開口部32a及び容器本体2の相対的な周方向の位置合わせが不要となる利点がある。   Moreover, in this embodiment, since the inclined surface 24 of the bottom part 22 of the container main body 2 is gradually inclined toward the radial center, the lower end opening part 32a of the suction pipe 32 and the container main body 2 are relatively arranged. There is an advantage that circumferential alignment is not required.

なお、本発明の技術範囲は、上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において、種々の変更を加えることが可能である。   The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

例えば、前述の実施形態では、窪み部23の底面23bに設けられる支持突部25上に吸い上げパイプ32の下端部を当接させた状態で支持する構成としているが、このような構成であることに限定されることはない。例えば、図4及び図5に示すように、平面視で十字状の支持突部25Aの上端部25aが吸い上げパイプ32の下端開口部32a内に挿入された構成とすることも可能である。この支持突部25Aは、窪み部23の内周面23cに対して離間して設けられている。支持突部25Aの上端部25aは、径方向の内側から外側に向かうに従い漸次、下方に向けて延びる曲線状に形成されている。尚、支持突部を多段状に形成するとともにその上端部を小径部に形成し、当該小径部を吸い上げパイプ32の下端開口部32a内に挿入する等、その形状は適宜変更することができる。
この場合には、吸い上げパイプ32の下端部の水平方向の移動が抑制され、吸い上げパイプ32の外周面32bと窪み部23の内周面23cとの間の隙間Sを確保することができる。
For example, in the above-described embodiment, the configuration is such that the lower end portion of the suction pipe 32 is in contact with the support protrusion 25 provided on the bottom surface 23b of the hollow portion 23, but such a configuration is used. It is not limited to. For example, as shown in FIGS. 4 and 5, the upper end 25 a of the cross-shaped support protrusion 25 </ b> A in a plan view may be inserted into the lower end opening 32 a of the suction pipe 32. The support protrusion 25A is provided apart from the inner peripheral surface 23c of the recess 23. The upper end 25a of the support protrusion 25A is formed in a curved shape that gradually extends downward as it goes from the inner side to the outer side in the radial direction. It is to be noted that the shape of the support protrusion can be changed as appropriate, for example, the support protrusion is formed in a multistage shape, the upper end thereof is formed in a small diameter portion, and the small diameter portion is inserted into the lower end opening 32 a of the suction pipe 32.
In this case, the horizontal movement of the lower end portion of the suction pipe 32 is suppressed, and a clearance S between the outer peripheral surface 32b of the suction pipe 32 and the inner peripheral surface 23c of the recess 23 can be secured.

また、窪み部23には、内周面23cに周方向に間隔をあけて縦リブが設けられていてもよい。この場合、これら縦リブの内端部は、吸い上げパイプ32の外周面32bに当接する。そして、周方向に隣り合う縦リブ同士の間の隙間と吸い上げパイプ32の内面とが連通している。   Moreover, the hollow part 23 may be provided with the longitudinal rib in the inner peripheral surface 23c at intervals in the circumferential direction. In this case, the inner ends of these vertical ribs abut on the outer peripheral surface 32 b of the suction pipe 32. And the clearance gap between the longitudinal ribs adjacent to the circumferential direction and the inner surface of the suction pipe 32 are connecting.

さらに、本実施形態では、内容物収容部20が径方向の外側から外筒26に囲繞された容器本体2とされているが、これに限定されることはなく、外筒26を省略することも可能である。
外筒26を設けない場合には、容器本体2(内容物収容部20)の底部22から下方に脚部を設ければよい。前記脚部としては、内容物収容部20と同径の円筒部、窪み部23の外面から放射状に形成される板状リブ、周方向に間隔を空けて設けられた複数の凸リブ、等を単独で、あるいは組み合わせて適宜採用することができる。
Furthermore, in the present embodiment, the content container 20 is the container body 2 surrounded by the outer cylinder 26 from the outside in the radial direction, but is not limited to this, and the outer cylinder 26 is omitted. Is also possible.
In the case where the outer cylinder 26 is not provided, a leg portion may be provided downward from the bottom portion 22 of the container main body 2 (content storage portion 20). As the leg portion, a cylindrical portion having the same diameter as the content accommodating portion 20, a plate-like rib formed radially from the outer surface of the recess portion 23, a plurality of convex ribs provided at intervals in the circumferential direction, etc. It can employ | adopt suitably independently or in combination.

また、吐出器3の押下ヘッド31、空気用シリンダ33、液用シリンダ34、装着キャップ35、及び吐出筒36の形状や各部の寸法などの構成は、適宜変更することが可能である。   In addition, the configuration of the pressing head 31, the air cylinder 33, the liquid cylinder 34, the mounting cap 35, and the discharge cylinder 36 of the discharger 3 can be appropriately changed.

その他、本発明の趣旨を逸脱しない範囲で、上述した実施形態における構成要素を周知の構成要素に置き換えることは適宜可能であり、また、上述した変形例を適宜組み合わせてもよい。   In addition, in the range which does not deviate from the meaning of this invention, it is possible to replace suitably the component in the embodiment mentioned above by the known component, and you may combine the modification mentioned above suitably.
