Description

【0001】
【発明の属する技術分野】
本発明は、エアゾール容器頭部に、マウンティングカップが巻締め部により装着されると共に、パイプ状のノズルが突設された操作部付スパウト基部の内部に、マウンティングカップに内蔵の弁機構から突出するステムに嵌着する流路が形成され、またノズルの先端よりも基端寄りの位置に、鼻腔の入口周辺部に当接する受液部が形成されることにより、この受液部で鼻腔を塞いだ状態で操作部の押下げ操作によりノズル先端から内容液を鼻腔に噴射させるようになった鼻腔用スパウトに関するものである。
【0002】
【従来の技術】
この種の鼻腔用スパウトは、特許文献1により周知であり、パイプ状ノズルの周面にフランジ状の受液部を形成して、洗浄液の噴射による洗浄時に受液部を鼻腔口に蓋として当てることにより、逆流してくる洗浄液を塞き止めて、垂れるのを防止しようとしている。しかしながら、使用後に液垂れにより容器或は手が汚れる可能性があり、また鼻腔が完全に閉鎖された場合の鼻腔内圧の上昇による不快感が生じる可能性が残されることを勘案して、特許文献2により、受液部からノズルに沿って容器外に廃液する溝を形成した鼻腔用噴射装置が開示されている。
【0003】
【特許文献1】
特開2000−93483号公報
【特許文献2】
特開2002−301151号公報
【0004】
【発明が解決しようとする課題】
この特許文献2による鼻腔用噴射装置の場合、廃液経路は決められるとしても単に容器外へ廃液するもので、容器或は手の汚れを確実に防止するのは難しく、特に携帯用の鼻腔用スパウトの場合は不都合である。
【0005】
本発明は、このような点に鑑みて、廃液を容器の頭部に溜めることのできる鼻腔用スパウトを提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明は、この目的を達成するために、請求項1により、エアゾール容器頭部に、弁機構を内蔵したマウンティングカップが巻締め部により装着されると共に、パイプ状のノズルが突設された操作部付スパウト基部の内部に、弁機構から突出するステムに嵌着する流路が形成され、またノズルの先端よりも基端寄りの位置に、鼻腔の入口周辺部に当接する受液部が形成されることにより、この受液部で鼻腔を塞いだ状態で操作部の押下げ操作によりノズル先端から内容液を鼻腔に噴射させるようになった鼻腔用スパウトにおいて、受液部に形成された排液口に連通し、かつ巻締め部よりも内側のマウンティングカップ面に排液を排出させる排液溝が、スパウト周面に沿って形成されたことを特徴とする。
【0007】
排液溝は、スパウト周面の外側もしくは内側に形成される。ノズルの先端部を鼻腔に挿入して、受液部を鼻腔の入口周辺部に当接させて塞いだ状態で、操作部を押し下げ操作すると、内溶液が鼻腔へ噴射されると共に、鼻腔内で逆流してきた廃液は受液部で塞き止められ、排液口から排液溝に流れ込んでマウンティングカップ面に排出される。
【0008】
【発明の実施の形態】
図1及び図2を基に本発明の実施の形態の一例による鼻腔用スパウトを説明する。このスパウトは、例えば洗浄液が充填された円筒状エアゾール容器1の頭頂部に装着されたマウンティングカップ2に内蔵の弁機構から突出するステム3に嵌着するスパウト基部10に、パイプ状のノズル11を突設して形成されている。ドーム状のスパウト基部10の内部には、上方へ弾性付勢されたステム3に基端部で嵌着する縦方向の中心流路14が形成されている。ノズル11の先端部には、噴射口15aを備えた噴口部材15が嵌合されている。スパウト基部10の上部には、押下げ操作用の操作部16が側方へ突設されている。
【0009】
ノズル11の先端から僅かに基端寄りの位置には、鼻腔の入口周辺部に当接するように、逆円錐である漏斗状の受液部20が形成されている。この受液部のノズル11に対して操作部16と反対側には、排液口21が形成されている。スパウト外周面、即ち受液部20より下方のノズル11部分及びスパウト基部10に沿って、排液溝22が縦方向へ露出して形成されている。この排液溝の下端23は、マウンティングカップ2のエアゾール容器1との巻締め部2aの内側で、かつボス部2bの周囲のマウンティングカップ面2cの上方に終端している。
【0010】
このように構成された鼻腔用スパウトの動作は次の通りである。鼻腔の洗浄に際しては、ノズル11の先端部を鼻腔に挿入して、受液部20を鼻腔の入口周辺部に当接させて塞いだ状態で、人差し指で操作部16を押し下げ操作すると、洗浄液が鼻腔へ噴射される。鼻腔内を逆流してきた廃液は受液部20に塞き止められ、その漏斗状の液受面に沿って排液口21から排液溝22に流れ込み、この排液溝に沿ってマウンティングカップ面2cに排出されて溜められる。したがって、ノズル11を鼻腔から抜いた際に液垂れが生じず、適時エアゾール容器1を傾倒させて外部に廃液することができる。特に、残液が微量の場合には、そのまま放置して乾燥させることもできる。
【0011】
図3及び図4は別の実施の形態による鼻腔用スパウトを示すもので、垂直上方に対して傾斜したパイプ状のノズル31付のスパウト基部30が、揺動式に肩カバー40に一体成形されている。肩カバー40は、外径が2段に変化する環状の周面部41、42を備えることにより、その段部がマウンティングカップ2の巻締め部2aに載置されると共に、周面部42の下端の突出部42aが、巻締め部2aの下端の凹部に外係合して、肩部をマウンティングカップ2と共にカバーする。
【0012】
肩カバー40の上部には、スパウト基部30を揺動させる円形開口部46を形成するように、平坦環状の上面周辺部44が形成されると共に、その操作部34と反対側の部分に、スパウト基部30の外周面35がインテグラルヒンジ部45を介して揺動可能に連結されている。
【0013】
ノズル31の先端よりも僅かに基端寄りの位置には、排液口37付きの逆円錐台状に膨出された受液部32が形成されている。スパウトのインテグラルヒンジ部45側は空洞状に形成され、外周面35に対して離間した内周面36間には、排液口37に連通する断面略円弧状の排液溝33が形成されている。その下端38は、マウンティングカップ面2cの上方に終端している。また、肩カバー40の周面部41には排出口49が形成されている。
【0014】
ノズル31を鼻腔に挿入した状態で、操作部34を人指し指で押下げ操作すると、スパウト基部30がインテグラルヒンジ部45を支点として揺動してステム3を下動させる。鼻腔内で逆流してきた廃液は排液口32から排液溝33に沿ってマウンティングカップ面2cに溜められる。したがって、ノズル31を鼻腔から抜いた後に、エアゾール容器1を傾倒させて、排出口49から外部に廃液することができる。
【0015】
尚、本発明は洗浄液に限らず、薬剤を内溶液とするエアゾール容器にも適用される。排液溝は、ノズルが垂直上向きに形成されている場合でも、スパウト周面に沿ってスパウト内部に形成することもできる。
【0016】
【発明の効果】
請求項1の発明によれば、廃液がマウンティングカップ内に溜まることにより、使用後に手或は容器が汚れることがなく、使用後に容器を傾倒させて洗面台等に排出させることができる。請求項2の発明によれば、揺動式に肩カバーに一体成形された鼻腔用スパウトにも適用される。請求項3の発明によれば、手或は容器の汚れが一層確実に回避される。請求項4の発明によれば、ノズルが斜め上向き形成されている場合でも汚れが確実に回避される。請求項5の発明によれば、液受面が逆円錐状に形成されていることにより、特にノズルが垂直上向きの場合でも汚れが確実に回避される。

TECHNICAL FIELD OF THE INVENTION
According to the present invention, the mounting cup is attached to the head of the aerosol container by the tightening portion, and the inside of the spout base portion with the operating portion provided with the pipe-shaped nozzle protrudes from the valve mechanism built in the mounting cup. A flow channel that fits into the stem is formed, and a liquid receiving portion that contacts the periphery of the entrance of the nasal cavity is formed at a position closer to the proximal end than the distal end of the nozzle, thereby closing the nasal cavity with the liquid receiving portion. The present invention relates to a spout for a nasal cavity in which a content liquid is jetted from a nozzle tip to a nasal cavity by a pressing operation of an operation unit in a stagnation state.
[0002]
[Prior art]
This type of nasal spout is well known from Patent Literature 1, and has a flange-shaped liquid receiving portion formed on the peripheral surface of a pipe-shaped nozzle, and the liquid receiving portion is applied as a lid to the nasal cavity mouth during cleaning by spraying a cleaning liquid. In this way, the cleaning liquid flowing backward is blocked and prevented from dripping. However, taking into account the possibility that the container or hand may become dirty due to dripping after use, and that there is a possibility that discomfort due to an increase in intranasal pressure when the nasal cavity is completely closed remains. No. 2 discloses a nasal injection device in which a groove for draining liquid from the liquid receiving portion to the outside of the container along the nozzle is formed.
[0003]
[Patent Document 1]
JP 2000-93483 A [Patent Document 2]
JP-A-2002-301151
[Problems to be solved by the invention]
In the case of the nasal injection device according to Patent Document 2, even if the waste liquid path is determined, the waste liquid is simply discharged to the outside of the container, and it is difficult to reliably prevent contamination of the container or the hand. In particular, a portable nasal spout is used. This is inconvenient.
[0005]
The present invention has been made in view of the above circumstances, and has as its object to provide a spout for a nasal cavity capable of storing waste liquid in the head of a container.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the present invention provides an operation in which a mounting cup having a built-in valve mechanism is mounted on a head of an aerosol container by a wrapping portion and a pipe-shaped nozzle is protrudingly provided. Inside the spout base, there is formed a flow channel that fits into the stem protruding from the valve mechanism, and at the position closer to the base end than the tip of the nozzle, a liquid receiving part that contacts the periphery of the entrance to the nasal cavity is formed. With this arrangement, in the nasal spout in which the nasal cavity is closed by the liquid receiving portion and the content liquid is ejected to the nasal cavity from the nozzle tip by a pressing operation of the operating portion, the drainage formed in the liquid receiving portion is formed. A drain groove is formed along the peripheral surface of the spout, the drain groove communicating with the liquid port and discharging the drain liquid to a surface of the mounting cup inside the tightening portion.
[0007]
The drain groove is formed outside or inside the spout peripheral surface. Inserting the tip of the nozzle into the nasal cavity, pressing the operating part down with the liquid receiving part in contact with the periphery of the entrance of the nasal cavity and closing it, the internal solution is sprayed into the nasal cavity and The waste liquid that has flowed backward is blocked by the liquid receiving part, flows into the drain groove from the drain port, and is discharged to the mounting cup surface.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
A nasal spout according to an embodiment of the present invention will be described with reference to FIGS. The spout has a pipe-shaped nozzle 11 attached to a spout base 10 fitted to a stem 3 protruding from a valve mechanism built in a mounting cup 2 mounted on the top of a cylindrical aerosol container 1 filled with a washing liquid, for example. It is formed to protrude. Inside the dome-shaped spout base 10, there is formed a vertical central flow path 14 fitted at the base end to the stem 3 urged upward elastically. A nozzle member 15 having a nozzle 15a is fitted to the tip of the nozzle 11. At the upper part of the spout base 10, an operation part 16 for a pressing operation is provided to protrude sideways.
[0009]
At a position slightly closer to the base end from the distal end of the nozzle 11, a funnel-shaped liquid receiving portion 20 having an inverted conical shape is formed so as to abut the periphery of the entrance of the nasal cavity. A drain port 21 is formed on the opposite side of the nozzle 11 of the liquid receiving section from the operation section 16. A drain groove 22 is formed to be exposed in the vertical direction along the spout outer peripheral surface, that is, along the nozzle 11 portion below the liquid receiving portion 20 and the spout base portion 10. The lower end 23 of the drain groove terminates inside the portion 2a for tightening the mounting cup 2 with the aerosol container 1 and above the mounting cup surface 2c around the boss 2b.
[0010]
The operation of the thus configured nasal spout is as follows. When the nasal cavity is washed, the tip of the nozzle 11 is inserted into the nasal cavity, and the liquid receiving unit 20 is brought into contact with the vicinity of the entrance of the nasal cavity to close the nasal cavity. It is injected into the nasal cavity. The waste liquid that has flowed back in the nasal cavity is blocked by the liquid receiving portion 20, flows into the drain groove 22 from the drain port 21 along the funnel-shaped liquid receiving surface, and flows along the drain groove into the mounting cup surface. It is discharged to 2c and stored. Therefore, no dripping occurs when the nozzle 11 is pulled out of the nasal cavity, and the aerosol container 1 can be tilted at an appropriate time to drain the liquid to the outside. In particular, when the amount of the residual liquid is very small, it can be left as it is and dried.
[0011]
3 and 4 show a nasal cavity spout according to another embodiment, in which a spout base 30 having a pipe-shaped nozzle 31 inclined vertically upward is integrally formed with a shoulder cover 40 in a swinging manner. ing. The shoulder cover 40 is provided with annular peripheral surfaces 41 and 42 whose outer diameters change in two steps, so that the step is placed on the tightening portion 2a of the mounting cup 2 and the lower end of the peripheral surface 42 is The protruding portion 42a is externally engaged with the concave portion at the lower end of the fastening portion 2a, and covers the shoulder portion together with the mounting cup 2.
[0012]
A flat annular upper surface peripheral portion 44 is formed at the upper portion of the shoulder cover 40 so as to form a circular opening 46 for swinging the spout base portion 30, and a spout is formed at a portion opposite to the operation portion 34. The outer peripheral surface 35 of the base 30 is swingably connected via an integral hinge 45.
[0013]
At a position slightly closer to the base end than the tip end of the nozzle 31, a liquid receiving portion 32 with a liquid discharge port 37 swelled in an inverted truncated cone shape is formed. The spout is formed in a hollow shape on the integral hinge portion 45 side, and a drain groove 33 having a substantially arc-shaped cross section communicating with the drain port 37 is formed between the inner peripheral surface 36 separated from the outer peripheral surface 35. ing. The lower end 38 terminates above the mounting cup surface 2c. An outlet 49 is formed in the peripheral surface 41 of the shoulder cover 40.
[0014]
When the operation unit 34 is pressed down with a forefinger while the nozzle 31 is inserted into the nasal cavity, the spout base 30 swings around the integral hinge 45 to move the stem 3 downward. The waste liquid that has flowed back in the nasal cavity is stored on the mounting cup surface 2c from the drain port 32 along the drain groove 33. Therefore, after the nozzle 31 has been pulled out of the nasal cavity, the aerosol container 1 can be tilted and drained from the outlet 49 to the outside.
[0015]
Note that the present invention is not limited to the cleaning liquid, but is also applicable to an aerosol container using a chemical as an internal solution. The drain groove can be formed inside the spout along the spout peripheral surface even when the nozzle is formed vertically upward.
[0016]
【The invention's effect】
According to the first aspect of the present invention, since the waste liquid accumulates in the mounting cup, the hand or the container does not become dirty after use, and the container can be tilted and discharged to the wash basin or the like after use. According to the second aspect of the present invention, the present invention is also applied to a nasal spout which is formed integrally with a shoulder cover in a swinging manner. According to the third aspect of the present invention, contamination of the hands or the container is more reliably avoided. According to the invention of claim 4, even when the nozzle is formed obliquely upward, dirt is reliably avoided. According to the fifth aspect of the present invention, since the liquid receiving surface is formed in an inverted conical shape, contamination can be reliably avoided even when the nozzle is vertically upward.
