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、例えば下記特許文献１および２に示されるような、内容物が収容されるとともに内容物の減少に伴いしぼみ変形する可撓性に富む内容器、および該内容器が内装されるとともに該内容器との間に外気を吸入する吸気孔が形成され、スクイズ変形可能で復元自在な外容器を有する容器本体と、該容器本体の口部に装着され、内容物を吐出する吐出口が形成された吐出キャップと、を備える吐出容器が知られている。
これらのうち、例えば特許文献１記載の吐出容器では、吐出キャップには、容器本体の口部の開口端縁上に配置され該口部を閉塞する有底筒状の中栓部材と、容器本体の口部および中栓部材に外装された有頂筒状の本体部材と、本体部材の頂壁部と中栓部材の底壁部との間に容器軸方向に延設された弁筒部材と、が備えられている。前記本体部材の頂壁部において、弁筒部材よりも径方向の外側に位置する部分には、外部と吸気孔とを連通する外気導入孔が形成されている。前記弁筒部材の外周面には、容器軸方向に弾性変形することで、外気導入孔と吸気孔との連通およびその遮断を切り替える環状の空気弁部が突設されている。 Conventionally, for example, as shown in Patent Documents 1 and 2 below, a flexible inner container that accommodates contents and squeezes and deforms as the contents decrease, and the inner container is internally installed and An intake hole for sucking outside air is formed between the inner container and a container body having a squeeze-deformable and recoverable outer container, and a discharge port that is attached to the mouth of the container body and discharges contents. There is known a discharge container including a discharged cap.
Among these, for example, in the discharge container described in Patent Document 1, the discharge cap is disposed on the opening edge of the mouth portion of the container body, and has a bottomed cylindrical plug member that closes the mouth portion, and the container body. And a valve body member extending in the container axial direction between the top wall portion of the main body member and the bottom wall portion of the inner plug member. , Is provided. In the top wall portion of the main body member, an outside air introduction hole that communicates the outside with the intake hole is formed in a portion located on the outer side in the radial direction from the valve cylinder member. An annular air valve portion is provided on the outer peripheral surface of the valve cylinder member so as to be elastically deformed in the container axial direction to switch communication between the outside air introduction hole and the intake hole and blocking the air hole.

ところでこの種の吐出容器では、空気弁部により外気導入孔と吸気孔との連通およびその遮断が切り替えられ、外容器が復元するときに、空気弁部が、容器軸方向に振動させられながら弾性変形することで、音鳴りが発生することが知られている。この音鳴りは、例えば下記特許文献３および４に示されるように、空気弁部の振動を抑えることで抑制することができる。 By the way, in this type of discharge container, the communication between the outside air introduction hole and the intake hole is switched by the air valve portion and the shutoff thereof, and when the outer container is restored, the air valve portion is elastic while being vibrated in the container axial direction. It is known that sounding is generated by deformation. This sounding can be suppressed by suppressing the vibration of the air valve portion as shown in Patent Documents 3 and 4 below, for example.

そこで前記従来の吐出容器において、空気弁部が容器軸方向に振動しながら弾性変形することを抑えるために、例えば空気弁部の外周縁部をその全周にわたって中栓部材の内周面に圧接させることが考えられる。しかしながらこの場合、空気弁部を容器軸方向に弾性変形させ難くなり、空気弁部の可動性を確保することが困難になる。 Therefore, in the conventional discharge container, in order to prevent the air valve portion from elastically deforming while vibrating in the container axial direction, for example, the outer peripheral edge portion of the air valve portion is pressed against the inner peripheral surface of the inner plug member over the entire circumference. It is possible to make it. However, in this case, it is difficult to elastically deform the air valve portion in the container axial direction, and it becomes difficult to ensure the mobility of the air valve portion.

本発明は、前述した事情に鑑みてなされたものであって、空気弁部の可動性を確保しつつ、音鳴りを抑制することができる吐出容器を提供することを目的とする。 This invention is made | formed in view of the situation mentioned above, Comprising: It aims at providing the discharge container which can suppress a sound noise, ensuring the mobility of an air valve part.

The discharge container according to the present invention is a flexible inner container that accommodates the contents and deforms in accordance with a decrease in the contents, and the inner container is provided with the inner container, and external air is provided between the inner container and the inner container. A container body having an intake hole for inhalation, having a squeeze-deformable and recoverable outer container, and a discharge cap mounted on a mouth portion of the container body and having a discharge port for discharging contents. A discharge container, wherein the discharge cap is disposed at the mouth portion and has a bottomed cylindrical inner plug member that closes the mouth portion, and is covered with the mouth portion and the inner plug member. A tubular body having a top with the discharge port formed in the portion, and extending in the container axial direction between the top wall portion of the main body member and the bottom wall portion of the inner plug member, A valve member communicating therewith, and the inner stopper member extends in the container axial direction. And a communication passage that communicates the inside of the inner container and the inside of the valve cylinder member is formed, and the inside of the communication path includes communication between the inside of the inner container and the inside of the valve cylinder member through the communication passage, and A discharge valve portion for switching the shut-off is fitted so as to be slidable along the container axial direction, and a portion of the top wall portion of the main body member that is located on the outer side in the radial direction than the valve tube member is provided with the discharge valve portion. An outside air introduction hole that communicates between the outside of the container and the intake hole is formed, and the outer peripheral surface of the valve cylinder member is elastically deformed in the container axial direction, thereby allowing communication between the intake hole and the outside air introduction hole and An annular air valve portion for switching the cut-off is projected, and the inner peripheral surface of the inner plug member facing the outer peripheral edge portion of the air valve portion is radially outside the contact portion of the outer peripheral edge portion. The air valve portion is moved along the container axis direction by sliding the contact portion. Wherein the convex portion to suppress the vibration when the elastic deformation is provided Te. The convex portion may be a vertical convex rib.

この発明では、当該吐出容器から内容物を吐出するときには、まず、容器本体をその径方向の内側に押し込んで、外容器をスクイズ変形させて内容器内の圧力を上昇させる。すると吐出弁部が、内容器内の内容物により押圧されて、容器軸方向に沿って内容器の外側に向けて弾性変位させられ、連通路を通して内容器内と弁筒部材内とが連通させられる。これにより、内容器内の内容物が、連通路、弁筒部材内および吐出口を通して外部に吐出される。
その後、容器本体の押し込みを停止、解除することで、内容器内の内容物による吐出弁部への押圧力を弱めると、吐出弁部が容器軸方向に沿って内容器の内側に復元変位し、連通路を通した内容器内と弁筒部材内との連通が遮断される。このとき吐出弁部が、連通路の内周面上を摺動しながら容器軸方向に沿って内容器の内側に復元変位することで、吐出口内の内容物が、吐出キャップの内側に引き込まれる。 In the present invention, when discharging the contents from the discharge container, first, the container body is pushed inward in the radial direction to squeeze the outer container to increase the pressure in the inner container. Then, the discharge valve part is pressed by the contents in the inner container and is elastically displaced toward the outside of the inner container along the container axial direction, and the inside of the inner container and the inside of the valve cylinder member are communicated through the communication path. It is done. Thereby, the contents in the inner container are discharged to the outside through the communication passage, the valve cylinder member, and the discharge port.
After that, by stopping and releasing the pushing of the container body, if the pressing force on the discharge valve part by the contents in the inner container is weakened, the discharge valve part is restored and displaced inside the inner container along the container axial direction. The communication between the inner container and the valve cylinder member through the communication passage is blocked. At this time, the discharge valve part is restored and displaced to the inside of the inner container along the container axial direction while sliding on the inner peripheral surface of the communication passage, whereby the contents in the discharge port are drawn into the inside of the discharge cap. .

ここで、連通路を通した内容器内と弁筒部材内との連通が遮断された状態で、容器本体の押し込みを解除すると、内容器が減容変形したまま外容器が復元変形しようとする。このとき、内容器と外容器との間に負圧が発生し、この負圧が、吸気孔を通して空気弁部に作用する。すると、空気弁部の外周縁部における接触部分が中栓部材の内周面の凸部上を容器軸方向に摺動しながら、空気弁部が容器軸方向に弾性変形することで、吸気孔と外気導入孔とが連通され、外気が、外気導入孔および吸気孔を通して内容器と外容器との間に吸入される。内容器と外容器との間の内圧が大気圧まで上昇すると、空気弁部の前記接触部分が凸部上を容器軸方向に摺動しながら空気弁部が容器軸方向に復元変形し、吸気孔と外気導入孔との連通が遮断される。これにより、内容物の吐出後に内容器の減容形状が保持される。 Here, when the pushing of the container body is released in a state where the communication between the inner container and the valve cylinder member through the communication passage is blocked, the outer container attempts to restore and deform while the inner container is reduced in volume. . At this time, a negative pressure is generated between the inner container and the outer container, and this negative pressure acts on the air valve portion through the intake hole. Then, the air valve portion is elastically deformed in the container axial direction while the contact portion in the outer peripheral edge portion of the air valve portion slides on the convex portion of the inner peripheral surface of the inner plug member in the container axial direction. And the outside air introduction hole communicate with each other, and outside air is sucked between the inner container and the outer container through the outside air introduction hole and the intake hole. When the internal pressure between the inner container and the outer container rises to atmospheric pressure, the contact portion of the air valve part slides on the convex part in the container axial direction, the air valve part is restored and deformed in the container axial direction, Communication between the hole and the outside air introduction hole is blocked. Thereby, the volume-reduced shape of the inner container is maintained after the contents are discharged.

当該吐出容器によれば、中栓部材の内周面に、前記凸部が設けられているので、空気弁部により、吸気孔と外気導入孔との連通、およびその遮断を切り替えるときに、空気弁部の外周縁部における接触部分に凸部上を摺動させることで、空気弁部の振動を抑えることができる。これにより、空気弁部の振動を抑えつつ、空気弁部を容器軸方向に弾性変形させることが可能になり、音鳴りの発生を抑制することができる。
また、空気弁部の外周縁部のうちの接触部分が、凸部に接触しているので、空気弁部の外周縁部のうち、接触部分以外の部分を、中栓部材の内周面から離間させておくことができる。したがって、例えば空気弁部の外周縁部が、この外周縁部の全周にわたって中栓部材の内周面に圧接されている場合などに比べて、空気弁部を容器軸方向に円滑に弾性変形させることが可能になり、空気弁部の可動性を確保することができる。 According to the discharge container, since the convex portion is provided on the inner peripheral surface of the inner plug member, when the communication between the intake hole and the outside air introduction hole is switched and the air-blocking is switched by the air valve portion, The vibration of the air valve portion can be suppressed by sliding the convex portion on the contact portion in the outer peripheral edge portion of the valve portion. Thereby, it becomes possible to elastically deform the air valve portion in the container axial direction while suppressing vibration of the air valve portion, and it is possible to suppress the generation of noise.
Moreover, since the contact part in the outer periphery part of an air valve part is contacting the convex part, parts other than a contact part are removed from the inner peripheral surface of an inner plug member among the outer periphery parts of an air valve part. Can be separated. Therefore, for example, the air valve portion is smoothly elastically deformed in the container axial direction as compared with the case where the outer peripheral edge portion of the air valve portion is pressed against the inner peripheral surface of the inner plug member over the entire circumference of the outer peripheral edge portion. Therefore, the mobility of the air valve portion can be ensured.

本発明に係る吐出容器によれば、空気弁部の可動性を確保しつつ、音鳴り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 noise while securing the mobility of the air valve portion.

オーバーキャップ１７は、吐出キャップ１６の本体部材２１の頂壁部２１ａを上方から覆っている。オーバーキャップ１７は、ヒンジ部を介して吐出キャップ１６に連結されている。オーバーキャップ１７には、吐出キャップ１６の前記吐出筒３０内に嵌合されるシール部１７ａが、下方に向けて突設されている。シール部１７ａは、容器軸Ｏと同軸の筒状に形成されている。シール部１７ａの下端面は、吐出キャップ１６の前記規制突部３２の上端面と容器軸Ｏ方向に対向している。 The overcap 17 covers the top wall portion 21a of the main body member 21 of the discharge cap 16 from above. The overcap 17 is connected to the discharge cap 16 via a hinge portion. The overcap 17 is provided with a seal portion 17a that is fitted into the discharge cylinder 30 of the discharge cap 16 so as to protrude downward. The seal portion 17a is formed in a cylindrical shape coaxial with the container axis O. The lower end surface of the seal portion 17a is opposed to the upper end surface of the restricting protrusion 32 of the discharge cap 16 in the container axis O direction.

前記吐出容器１０では、吐出キャップ１６にオーバーキャップ１７が装着された状態で、吐出弁部３１を上方に向けて弾性変位させようとしても、吐出キャップ１６の規制突部３２とオーバーキャップ１７のシール部１７ａとが互いに当接し、吐出弁部３１の弾性変位を規制する。
そこで、吐出容器１０から内容物を吐出するときには、まず、吐出キャップ１６からオーバーキャップ１７を外す。その後、容器本体１４を径方向の内側に押し込んでスクイズ変形（弾性変形）させ、内容器１１を外容器１３とともに変形させ減容させる。
すると、内容器１１内の圧力が上昇し、内容器１１内の内容物が貫通孔２７を通して吐出弁部３１を押圧することとなり、弾性連結片３３が弾性変形させられて吐出弁部３１が上方に向けて弾性変位させられる。これにより、連通路２９を通して内容器１１内と弁筒部材２２内とが連通させられて、内容器１１内の内容物が、貫通孔２７、連通路２９、弁筒部材２２内、吐出筒３０内および吐出口１５を通して外部に吐出される。 In the discharge container 10, even when an attempt is made to elastically displace the discharge valve portion 31 upward with the overcap 17 mounted on the discharge cap 16, the sealing protrusion 32 and the seal of the overcap 17 are sealed. The parts 17a come into contact with each other, and the elastic displacement of the discharge valve part 31 is restricted.
Therefore, when discharging the contents from the discharge container 10, first, the overcap 17 is removed from the discharge cap 16. Thereafter, the container body 14 is pushed inward in the radial direction to be squeezed (elastically deformed), and the inner container 11 is deformed together with the outer container 13 to reduce the volume.
Then, the pressure in the inner container 11 rises, and the content in the inner container 11 presses the discharge valve part 31 through the through hole 27, and the elastic connecting piece 33 is elastically deformed so that the discharge valve part 31 moves upward. It is elastically displaced toward Thereby, the inside of the inner container 11 and the inside of the valve cylinder member 22 are communicated with each other through the communication path 29, and the contents in the inner container 11 are passed through the through hole 27, the communication path 29, the inside of the valve cylinder member 22, and the discharge cylinder 30. It is discharged to the outside through the inside and the discharge port 15.

その後、吐出容器１０の押し込みを停止したり解除したりすることで、内容器１１内の内容物による吐出弁部３１への押圧力を弱めると、弾性連結片３３の弾性復元力により、吐出弁部３１が下方に復元変位させられ、連通路２９を通した内容器１１内と弁筒部材２２内との連通が遮断される。このとき吐出弁部３１が、連通路２９の内周面上を摺動しながら下方に復元変位することで、吐出口１５内の内容物が吐出キャップ１６の内側に引き込まれる。 After that, when the pushing force of the contents in the inner container 11 to the discharge valve portion 31 is weakened by stopping or releasing the pushing of the discharge container 10, the discharge valve 10 is caused by the elastic restoring force of the elastic connecting piece 33. The portion 31 is restored and displaced downward, and the communication between the inner container 11 and the valve cylinder member 22 through the communication passage 29 is blocked. At this time, the discharge valve portion 31 is restored and displaced downward while sliding on the inner peripheral surface of the communication passage 29, whereby the contents in the discharge port 15 are drawn into the discharge cap 16.

ここで、連通路２９を通した内容器１１内と弁筒部材２２内との連通が遮断された状態で、容器本体１４の押圧を解除すると、内容器１１が減容変形したまま外容器１３が復元変形しようとする。このとき、内容器１１と外容器１３との間に負圧が発生し、この負圧が、吸気孔１２を通して空気弁部３６に作用する。すると、空気弁部３６の外周縁部３６ａにおける接触部分が、中栓部材２０の内周面の縦凸リブ３５上を容器軸Ｏ方向に摺動しながら、空気弁部３６が容器軸Ｏ方向に弾性変形することで、空気弁部３６が弁座部３７から離反して、吸気孔１２と外気導入孔３４とが連通される。これにより、外気が、外気導入孔３４、外気流通孔２６および吸気孔１２を通して外容器１３と内容器１１との間に吸入される。 Here, when the communication between the inside of the inner container 11 through the communication passage 29 and the inside of the valve cylinder member 22 is blocked, when the pressure on the container body 14 is released, the inner container 11 remains deformed and the outer container 13 remains reduced in volume. Tries to restore and transform. At this time, a negative pressure is generated between the inner container 11 and the outer container 13, and this negative pressure acts on the air valve portion 36 through the intake hole 12. Then, the contact portion at the outer peripheral edge portion 36a of the air valve portion 36 slides on the longitudinal convex rib 35 on the inner peripheral surface of the inner plug member 20 in the container axis O direction, while the air valve portion 36 is in the container axis O direction. By being elastically deformed, the air valve portion 36 is separated from the valve seat portion 37, and the intake hole 12 and the outside air introduction hole 34 are communicated with each other. Thus, outside air is sucked between the outer container 13 and the inner container 11 through the outside air introduction hole 34, the outside air circulation hole 26, and the intake hole 12.

そして、外容器１３と内容器１１との間の内圧が大気圧まで上昇すると、空気弁部３６の前記接触部分が縦凸リブ３５上を容器軸Ｏ方向に摺動しながら、空気弁部３６が容器軸Ｏ方向に復元変形し、吸気孔１２と外気導入孔３４との連通が遮断される。これにより、内容物の吐出後に内容器１１の減容形状が保持される。この状態から、再び容器本体１４の外容器１３をスクイズ変形させると、外容器１３と内容器１１との間の内圧が正圧となり、この正圧によって内容器１１が減容変形され、前述の作用により内容物が吐出される。 When the internal pressure between the outer container 13 and the inner container 11 rises to atmospheric pressure, the contact portion of the air valve part 36 slides on the longitudinal convex rib 35 in the container axis O direction, while the air valve part 36. Is restored and deformed in the direction of the container axis O, and the communication between the intake hole 12 and the outside air introduction hole 34 is blocked. Thereby, the volume reduction shape of the inner container 11 is maintained after the contents are discharged. From this state, when the outer container 13 of the container body 14 is squeezed again, the internal pressure between the outer container 13 and the inner container 11 becomes a positive pressure, and the inner container 11 is reduced in volume by this positive pressure. The contents are discharged by the action.

以上説明したように、本実施形態に係る吐出容器１０よれば、中栓部材２０の内周面に、前記縦凸リブ３５が設けられているので、空気弁部３６により、吸気孔１２と外気導入孔３４との連通、およびその遮断を切り替えるときに、空気弁部３６の外周縁部３６ａにおける接触部分に縦凸リブ３５上を摺動させることで、空気弁部３６の振動を抑えることができる。これにより、空気弁部３６の振動を抑えつつ、空気弁部３６を容器軸Ｏ方向に弾性変形させることが可能になり、音鳴りの発生を抑制することができる。
また、空気弁部３６の外周縁部３６ａのうちの接触部分が、縦凸リブ３５に接触しているので、空気弁部３６の外周縁部３６ａのうち、接触部分以外の部分を、中栓部材２０の内周面から離間させておくことができる。したがって、例えば空気弁部の外周縁部が、この外周縁部の全周にわたって中栓部材の内周面に圧接されている場合などに比べて、空気弁部３６を容器軸Ｏ方向に円滑に弾性変形させることが可能になり、空気弁部３６の可動性を確保することができる。 As described above, according to the discharge container 10 according to the present embodiment, since the longitudinal convex rib 35 is provided on the inner peripheral surface of the inner plug member 20, the air valve portion 36 and the outside air When switching the communication with the introduction hole 34 and the blocking thereof, the vibration of the air valve portion 36 can be suppressed by sliding the longitudinal convex rib 35 on the contact portion in the outer peripheral edge portion 36a of the air valve portion 36. it can. Thereby, it becomes possible to elastically deform the air valve part 36 in the container axis O direction while suppressing the vibration of the air valve part 36, and the generation of noise can be suppressed.
Moreover, since the contact part in the outer periphery part 36a of the air valve part 36 is contacting the vertical convex rib 35, parts other than a contact part are plugged out of the outer periphery part 36a of the air valve part 36. It can be separated from the inner peripheral surface of the member 20. Therefore, for example, compared with the case where the outer peripheral edge portion of the air valve portion is pressed against the inner peripheral surface of the inner plug member over the entire periphery of the outer peripheral edge portion, the air valve portion 36 is smoothly moved in the container axis O direction. It becomes possible to elastically deform, and the mobility of the air valve part 36 can be ensured.
