Description

本発明は、吐出容器に関する。   The present invention relates to a discharge container.

従来から、内容物の減少に伴い減容変形する内容器、および内容器が内装されるとともに弾性変形可能な外容器を備える容器本体と、容器本体の口部に装着され、天壁部に内容物を吐出する吐出孔が形成された有頂筒状の吐出ノズルと、吐出ノズル内に配設され、吐出孔と内容器内とを連通する連通孔が形成された中栓と、中栓における連通孔の開口周縁部上に、上方に向けて離反自在に配設され、連通孔を開放自在に閉塞する弁部を有する弁体と、を備える吐出容器が知られている。この種の吐出容器として、例えば下記特許文献1に示されるような、天壁部の上面における吐出孔の開口周縁部に窪み部が形成された構成が知られている。
この吐出容器では、外容器を径方向の内側に向けて弾性変形させると、弁体の弁部が、中栓における連通孔の開口周縁部から上方に離反することで、内容器内と吐出孔とが連通孔を通して連通し、内容物が吐出孔から吐出される。その後、弁体の弁部が、中栓における連通孔の開口周縁部上に当接するとともに、外容器が復元変形すると、外容器に形成された外気導入孔を通して、外容器と内容器との間に外気が導入され、内容器が減容変形したままの状態に保たれる。これにより、吐出孔から内容器内に向けて外気が導入されることが抑えられる。
Conventionally, an inner container that deforms and deforms as the contents are reduced, and a container body that includes an inner container and an outer container that can be elastically deformed, and the mouth of the container body are attached to the top wall. A top-end cylindrical discharge nozzle in which a discharge hole for discharging an object is formed; an inner plug provided in the discharge nozzle and having a communication hole communicating with the discharge hole and the inner container; 2. Description of the Related Art A discharge container is known that includes a valve body that is disposed on an opening peripheral edge of a communication hole so as to be separated upward and has a valve portion that freely closes the communication hole. As this type of discharge container, for example, as shown in Patent Document 1 below, a configuration is known in which a depression is formed at the opening peripheral edge of the discharge hole on the top surface of the top wall.
In this discharge container, when the outer container is elastically deformed toward the inside in the radial direction, the valve part of the valve body is separated upward from the opening peripheral edge of the communication hole in the inner plug, so that the inside of the inner container and the discharge hole Are communicated through the communication hole, and the contents are discharged from the discharge hole. After that, when the valve part of the valve body comes into contact with the peripheral edge of the opening of the communication hole in the inner plug, and the outer container is restored and deformed, it passes between the outer container and the inner container through the outer air introduction hole formed in the outer container. Outside air is introduced to the inner container, and the inner container is kept in a deformed and deformed state. Thereby, it is suppressed that outside air is introduced into the inner container from the discharge hole.

しかしながら、前記従来の吐出容器では、吐出孔から内容器内に向けて外気が導入されることがないので、天壁部上に残存した内容物が吐出孔から内容器内に向けて吸い込まれることがない上に、天壁部の上面における吐出孔の開口周縁部に窪み部が形成されているため、内容物が天壁部上に残存しやすいという問題があった。   However, in the conventional discharge container, since the outside air is not introduced from the discharge hole into the inner container, the content remaining on the top wall is sucked into the inner container from the discharge hole. In addition, there is a problem in that the contents are likely to remain on the top wall portion because the recess portion is formed in the opening peripheral edge portion of the discharge hole on the top surface of the top wall portion.

本発明は、このような事情に鑑みてなされたものであって、その目的は、内容物が吐出ノズルの天壁部上に残存するのを抑制することができる吐出容器を提供することである。   This invention is made | formed in view of such a situation, The objective is to provide the discharge container which can suppress that the content remains on the ceiling wall part of a discharge nozzle. .

本発明に係る吐出容器は、内容物の減少に伴い減容変形する内容器、および前記内容器が内装されるとともに弾性変形可能な外容器を備える容器本体と、前記容器本体の口部に装着され、天壁部に内容物を吐出する吐出孔が形成された有頂筒状の吐出ノズルと、前記吐出ノズル内に配設され、前記吐出孔と前記内容器内とを連通する連通孔が形成された中栓と、前記中栓における前記連通孔の開口周縁部上に、上方に向けて離反自在に配設され、前記連通孔を開放自在に閉塞する弁部を有する弁体と、を備え、前記吐出ノズルの天壁部には、上方に向けて突出する集液部が形成され、前記集液部は、上端部が他よりも上方に位置する集液頂部を有することを特徴とする。   A discharge container according to the present invention is attached to a container body including an inner container whose volume is reduced and deformed as the contents are reduced, an outer container in which the inner container is housed and elastically deformable, and a mouth portion of the container body A top-end cylindrical discharge nozzle having a discharge hole for discharging contents on the top wall, and a communication hole that is disposed in the discharge nozzle and communicates the discharge hole with the inside of the inner container. An inner plug formed, and a valve body having a valve portion which is disposed on the peripheral edge of the opening of the communication hole in the inner plug so as to be separated from the upper part and freely closes the communication hole. A liquid collecting portion protruding upward is formed on the top wall portion of the discharge nozzle, and the liquid collecting portion has a liquid collecting top portion whose upper end portion is located above the other. To do.

本発明によれば、吐出ノズルの天壁部に集液部が形成されているので、吐出孔から吐出されて天壁部の上面に至った内容物が、集液部を伝って集液頂部に集められ、滴となって落下する。これにより、例えば、天壁部の上面における吐出孔の開口周縁部に窪み部が形成された構成と比べて、滴下後に天壁部上に残存する内容物を低減することができる。
なお、天壁部に前記窪み部が形成され、かつ容器本体の口部に着脱自在に装着されて吐出孔を開放可能に閉塞するキャップを備える構成において、前記窪み部に内容物が溜まると、キャップを容器本体の口部に装着し、キャップの天壁に形成された突部を前記窪み部に進入させたときに、前記窪み部内の内容物が溢れる不具合が生ずるが、本発明では、このような不具合が生ずることがない。
According to the present invention, since the liquid collection part is formed on the top wall part of the discharge nozzle, the content discharged from the discharge hole and reaching the top surface of the top wall part passes through the liquid collection part and reaches the liquid collection top part. Collected as a drop. Thereby, for example, the content remaining on the top wall portion after dropping can be reduced as compared with the configuration in which the depression portion is formed in the opening peripheral portion of the discharge hole on the upper surface of the top wall portion.
In addition, in the configuration including the cap formed in the top wall portion and detachably attached to the mouth portion of the container main body so as to close the discharge hole so that the discharge hole can be opened, the contents accumulate in the recess portion. When the cap is attached to the mouth of the container body and the protrusion formed on the top wall of the cap is made to enter the recess, there is a problem that the content in the recess overflows. Such problems do not occur.

ここで、前記集液部の一部は、前記天壁部における前記吐出孔の開口周縁部に配置され、前記集液頂部は、前記天壁部において前記吐出孔の開口周縁部から離れた部分に配置され、前記集液部は、前記一部から前記集液頂部に向かうに従い漸次、上方に向けて延びてもよい。   Here, a part of the liquid collection part is arranged at an opening peripheral part of the discharge hole in the top wall part, and the liquid collection top part is a part away from the opening peripheral part of the discharge hole in the top wall part. The liquid collection part may extend upward gradually from the part toward the liquid collection top part.

この場合、集液部の一部が、天壁部における吐出孔の開口周縁部に位置しているので、吐出孔を通して天壁部の上面に至った内容物が、即座に集液部の前記一部に到達する。そして、集液部が、前記一部から集液頂部に向かうに従い漸次、上方に向けて延びているので、集液部の前記一部に到達した内容物は、円滑に集液頂部に導かれる。
以上より、吐出孔から吐出された内容物が、天壁部上に拡散して付着するのを抑制することが可能になり、天壁部上に残存する内容物を確実に低減することができる。
In this case, since a part of the liquid collection part is located at the opening peripheral part of the discharge hole in the top wall part, the contents that have reached the upper surface of the top wall part through the discharge hole are immediately Reach part. Since the liquid collection part gradually extends upward from the part toward the liquid collection top part, the contents that have reached the part of the liquid collection part are smoothly guided to the liquid collection top part. .
As described above, it becomes possible to suppress the content discharged from the discharge holes from diffusing and adhering to the top wall portion, and the content remaining on the top wall portion can be reliably reduced. .

また、前記集液部は、前記天壁部において、この天壁部の上面視で前記吐出孔の中心を通る第1基準線より一方側に位置する部分の全域にわたって形成されるとともに、前記第1基準線から前記第1基準線に直交する方向に離れるに従い漸次、上方に向けて延びてもよい。   In addition, the liquid collection part is formed over the entire region of the top wall part that is located on one side of the first reference line passing through the center of the discharge hole in a top view of the top wall part. The distance from the first reference line may gradually extend upward as the distance from the first reference line increases in the direction orthogonal to the first reference line.

この場合、集液部が、天壁部において、前記第1基準線より一方側に位置する部分の全域にわたって形成されるとともに、前記第1基準線から前記第1基準線に直交する方向に離れるに従い漸次、上方に向けて延びているので、集液頂部の上端部が、前記第1基準線の延びる方向の幅を有することとなり、この部分が鋭利に尖るのを抑えることが可能になり、使用者がこの吐出容器の使用時に不安感を抱くのを防ぐことができる。   In this case, the liquid collection portion is formed over the entire area of the top wall portion located on one side of the first reference line, and is separated from the first reference line in a direction orthogonal to the first reference line. Accordingly, the upper end portion of the liquid collection top portion has a width in the direction in which the first reference line extends, and this portion can be prevented from being sharply sharpened. It is possible to prevent the user from feeling uneasy when using the discharge container.

また、前記天壁部は上面視円形状を呈し、前記集液頂部は、前記天壁部の外周縁部に形成され、前記吐出孔は、前記天壁部の中央部に形成され、前記集液頂部は、前記天壁部の上面視において、前記吐出孔を通り前記第1基準線に直交する第2基準線上に配置され、前記天壁部は、前記集液頂部の位置する周方向に沿う部分から周方向に離れるに従い漸次、下方に向けて延びてもよい。   The top wall portion has a circular shape in a top view, the liquid collection top portion is formed in an outer peripheral edge portion of the top wall portion, and the discharge hole is formed in a central portion of the top wall portion. The top of the liquid is disposed on a second reference line passing through the discharge hole and orthogonal to the first reference line in the top view of the top wall, and the top wall is in a circumferential direction where the top of the liquid collection is located. The distance may gradually extend downward from the portion along the circumferential direction.

この場合、吐出孔が天壁部の中央部に形成され、集液頂部が前記第2基準線上に配置されているので、吐出孔から吐出されて集液部の前記一部に至った内容物が、天壁部上を拡散せずに集液頂部に向けて直進しやすくなり、内容物を円滑に滴下することができるとともに、天壁部上に残存する内容物をより一層確実に低減することができる。   In this case, since the discharge hole is formed in the central portion of the top wall portion and the liquid collection top portion is disposed on the second reference line, the contents discharged from the discharge hole and reaching the part of the liquid collection portion However, it becomes easy to go straight toward the top of the liquid collection without diffusing on the top wall part, and the contents can be dripped smoothly, and the contents remaining on the top wall part can be more reliably reduced. be able to.

本発明に係る吐出容器によれば、内容物が吐出ノズルの天壁部上に残存するのを抑制することができる。   According to the discharge container according to the present invention, it is possible to suppress the contents from remaining on the top wall portion of the discharge nozzle.

以下、本実施形態の吐出容器1の作用について説明する。
吐出容器1から内容物を吐出させる際には、まず、容器本体2の口部3からキャップ8を取り外して、吐出孔12を露出させ、その後、吐出容器1を口部3が下方に位置し、かつ容器本体2の底部(不図示)が上方に位置する倒立姿勢または傾斜姿勢とする。この状態で、外気導入孔を指で閉塞し、かつ容器本体2の外容器6をスクイズ変形させると、内容器4が外容器6とともに変形して減容される。この減容変形に伴い内容器4の内圧が正圧となり、この正圧によって弁部31の周縁部35が弾性変形し、連通孔21が開放され、吐出孔12と内容器4の内部とが連通される。
Hereinafter, the operation of the discharge container 1 of the present embodiment will be described.
When discharging the contents from the discharge container 1, first, the cap 8 is removed from the mouth 3 of the container body 2 to expose the discharge hole 12, and then the discharge container 1 is positioned below the mouth 3. In addition, an inverted posture or an inclined posture in which the bottom portion (not shown) of the container body 2 is positioned upward is used. In this state, when the outside air introduction hole is closed with a finger and the outer container 6 of the container body 2 is squeezed, the inner container 4 is deformed together with the outer container 6 and the volume is reduced. Along with this volumetric deformation, the internal pressure of the inner container 4 becomes positive pressure, the positive pressure causes the peripheral edge 35 of the valve portion 31 to elastically deform, the communication hole 21 is opened, and the discharge hole 12 and the inside of the inner container 4 are connected. Communicated.

このように弁部31が開かれると、内容器4内の内容物が、中栓20の内周面と、押さえ筒部材40および脚部32の各外周面と、の間を通過した後、連通孔21を通過する。連通孔21を通過した内容物は、弁部31の上面と吐出ノズル10の天壁部11の下面との間の空間に流れ込み、吐出孔12から吐出される。この際、吐出孔12から吐出されて天壁部11の上面に至った内容物は、集液部25を伝って集液頂部25aに集められ、滴となって落下する。   When the valve part 31 is thus opened, after the contents in the inner container 4 pass between the inner peripheral surface of the inner plug 20 and the outer peripheral surfaces of the presser cylinder member 40 and the leg part 32, It passes through the communication hole 21. The contents that have passed through the communication hole 21 flow into the space between the upper surface of the valve portion 31 and the lower surface of the top wall portion 11 of the discharge nozzle 10 and are discharged from the discharge hole 12. At this time, the contents discharged from the discharge hole 12 and reaching the upper surface of the top wall portion 11 are collected in the liquid collection top portion 25a through the liquid collection portion 25 and fall as droplets.

内容物の吐出後、内容器4の内圧が低下すると、弁部31の周縁部35が弁座24の上面に着座して、吐出孔12と内容器4の内部との連通が遮断される。このように弁部31が閉じられることにより、内容器4が密封され、さらに手指による外気導入孔の閉塞、およびスクイズ変形を解除すると、外容器6は復元変形しようとする。このとき、内容器4が密封されているため、外容器6と内容器4との間に負圧が発生する。すると、外容器6の上述した外気導入孔を通して外気が外容器6と内容器4との間に導入される。このように、外容器6と内容器4との間に外気が導入されることにより、内容器4の減容形状が保持される。
以上により吐出容器1を用いた内容物の吐出動作が完了する。
When the internal pressure of the inner container 4 decreases after the contents are discharged, the peripheral edge portion 35 of the valve portion 31 is seated on the upper surface of the valve seat 24 and the communication between the discharge hole 12 and the inside of the inner container 4 is blocked. When the valve portion 31 is closed in this manner, the inner container 4 is sealed, and when the blocking of the outside air introduction hole by the fingers and the squeeze deformation are released, the outer container 6 tends to be restored and deformed. At this time, since the inner container 4 is sealed, a negative pressure is generated between the outer container 6 and the inner container 4. Then, outside air is introduced between the outer container 6 and the inner container 4 through the above-described outside air introduction hole of the outer container 6. In this way, by introducing outside air between the outer container 6 and the inner container 4, the volume reduction shape of the inner container 4 is maintained.
Thus, the content discharge operation using the discharge container 1 is completed.

以上詳述したように、本実施形態の吐出容器1では、内容物が、集液頂部25aから滴となって落下することから、例えば、吐出ノズル10の天壁部11の上面における吐出孔12の開口周縁部に窪み部が形成された構成と比べて、滴下後に天壁部11上に残存する内容物を低減することができる。   As described above in detail, in the discharge container 1 of the present embodiment, the contents fall as droplets from the liquid collection top portion 25a, and thus, for example, the discharge holes 12 on the top surface of the top wall portion 11 of the discharge nozzle 10. Compared with the structure in which the hollow portion is formed in the opening peripheral portion, the content remaining on the top wall portion 11 after dropping can be reduced.

また、集液部25の前記一部25bが、天壁部11における吐出孔12の開口周縁部に位置しているので、吐出孔12を通して天壁部11の上面に至った内容物が、即座に集液部25の前記一部25bに到達する。そして、集液部25が、前記一部25bから集液頂部25aに向かうに従い漸次、上方に向けて延びているので、集液部25の前記一部25bに到達した内容物は、円滑に集液頂部25aに導かれる。
以上より、吐出孔12から吐出された内容物が、天壁部11上に拡散して付着するのを抑制することが可能になり、天壁部11上に残存する内容物を確実に低減することができる。
Further, since the part 25b of the liquid collection part 25 is located at the opening peripheral edge of the discharge hole 12 in the top wall part 11, the contents reaching the upper surface of the top wall part 11 through the discharge hole 12 are immediately To the part 25 b of the liquid collecting part 25. And since the liquid collection part 25 is gradually extended upwards as it goes to the liquid collection top part 25a from the said part 25b, the contents which reached the said part 25b of the liquid collection part 25 are collected smoothly. It is guided to the liquid top 25a.
As described above, the contents discharged from the discharge holes 12 can be prevented from diffusing and adhering to the top wall portion 11, and the contents remaining on the top wall portion 11 can be reliably reduced. be able to.

また、集液部25が、天壁部11において、第1基準線L1より一方側に位置する部分の全域にわたって形成されるとともに、第1基準線L1から前記直交方向に離れるに従い漸次、上方に向けて延びているので、集液頂部25aの上端部が、第1基準線L1の延びる方向の幅を有することとなり、この部分が鋭利に尖るのを抑えることが可能になり、使用者がこの吐出容器1の使用時に不安感を抱くのを防ぐことができる。
また、吐出孔12が天壁部11の中央部に形成され、集液頂部25aが第2基準線L2上に配置されているので、吐出孔12から吐出されて集液部25の前記一部25bに至った内容物が、天壁部11上を拡散せずに集液頂部25aに向けて直進しやすくなり、内容物を円滑に滴下することができるとともに、天壁部11上に残存する内容物をより一層確実に低減することができる。
In addition, the liquid collection part 25 is formed over the entire area of the top wall part 11 located on one side of the first reference line L1, and gradually rises upward as the distance from the first reference line L1 increases in the orthogonal direction. Therefore, the upper end portion of the liquid collection top portion 25a has a width in the extending direction of the first reference line L1, and it is possible to suppress sharpening of this portion, and the user can It is possible to prevent anxiety when using the discharge container 1.
Moreover, since the discharge hole 12 is formed in the center part of the top wall part 11, and the liquid collection top part 25a is arrange | positioned on the 2nd reference line L2, it is discharged from the discharge hole 12 and said part of the liquid collection part 25 is included. The content that has reached 25b is likely to travel straight toward the liquid collection top portion 25a without diffusing on the top wall portion 11, so that the content can be dropped smoothly and remain on the top wall portion 11. The contents can be reduced more reliably.
