Description

【０００１】
【発明の属する技術分野】
この発明は、容器の口部に関し、さらに詳しくは内容物を裏もれさせることなく、ノズル部から切れ良く滴下できる容器の口部に関する。
【０００２】
【従来の技術】
従来、図１６及び図１７に示すように、チューブ容器本体１００の口部１０１に嵌合される、中栓体１０２の球体収納部１０３に、球体１０５を有するチューブ容器がある。そして、所望する滴下機能を有するものにあっては、球体収納部１０３の表面に、少なくとも１本以上の縦溝１０４を形成した球体を有するチューブ容器がある。このように、球体１０５を設ける理由は、内容物を抽出した後にエアーバックを防止するためであり、又縦溝１０４を形成するのは、内容物を少量ずつ滴下抽出するためである。
【０００３】
【発明が解決しようとする課題】
しかしながら、このようなチューブ容器にあっては、以下に示す欠点があった。
（１）ノズル１０６の形状が、先端部にいくにつれて、徐々に外径が細くなる形状を呈しているため、図１６に示すように、横向きに傾けて内容物を滴下した場合、内容物がノズル部１０６の外周面を伝う、所謂裏もれ現象が発生する欠点がある。
（２）内容物の抽出後、エアーバックを完全に防止するために、球体１０５と、この球体１０５が収納される球体収納部１０３の下止部１０７との間に隙間がないために、内容物を抽出した後、エアーバックが生じないので、チューブ容器本体１００の胴部が凹んだままの状態になる。したがって、次の絞り出し操作が頗る困難になる欠点があった。
（３）球体１０５が、球体収納部１０３内を移動する移動距離Ｙが大きいため（Ｙ＝０．７〜１．４）、内容物が突発的に抽出する欠点がある。
【０００４】
この発明は、このような従来の課題に着目してなされたもので、内容物を裏もれさせることなく、ノズル部から切れ良く滴下できると共に、絞り出し操作が良好であり、かつ内容物が突発的に抽出するのを防止した、容器の口部を提供することを目的とする。

【発明の実施の形態】
次に、この発明の実施の形態を図面に基づいて説明する。
図１〜図１０は、本発明に係る球体を有するチューブを示す図面であり、図１及び図３は、この発明に係る第１実施の形態を示す図面である。チューブ容器１は従来公知の単層、多層又はラミネートのチューブ容器である。図１に示すように、容器の口部３は、チューブ容器の口部２に嵌入されている。容器の口部３は、上方に通路４が形成され、この通路４の下方に連続して、内径が拡大された球体収納部５が形成されている。この球体収納部５の内径は、球体６の直径より若干大きく構成され、この球体収納部５の下方には、球体６の直径より若干小さく形成された下止部７が、半径方向内側に膨出して形成されている。この下止部７で球体６が支持されると共に、球体６が下止部７に密接する場合には、この下止部７と球体６の相互作用により、逆止弁機能が発揮され、密接しない場合には、若干のエアーバック効果を有する。すなわち、図４及び図５に示すように、下止部７には突出部７ａが形成される場合と、図６に示すように突出部７ａが形成されないものとがある。なお、球体６は、この下止部７の下方から球体収納部５に無理挿入される。
【００１５】
又、第１実施の形態において、必要に応じて球体収納部５の内周面に、少なくとも１本以上の縦溝８が形成されている。この縦溝８の形成により、１回で抽出される内容物の滴下量を決定できる。縦溝８の幅、溝深さ、数については、内容物の粘度等により自由に決定できる。例えば、縦溝１本で、突出部７ａを形成した場合は、低粘度の内容物として、例えば内容物が水虫薬等の場合に適する。また、縦溝３本で、突出部７ａを形成した場合は、高粘度の内容物として、例えば内容物がオイル類、クリーム類等の場合に適する。さらに、縦溝３本で、突出部７ａを形成しない場合は、高粘度の内容物であり、空気に触れてはならない内容物に適する。また、縦溝８に代えて、球体収納部５の内周面または球体６の表面に、シボ加工が施されたものであってもよい。シボ加工の深さは、同様に内容物の粘度、内容物の１回の滴下量等によって適宜に決定することができる。例えば、内容物の粘度が低い場合は、最大深さは１４μｍ程度、そして、内容物の粘度が高い場合は、最大深さ８０μｍ程度等任意に決定することができる。なお、容器の口部３をチューブ容器の口部２に嵌合するタイプ以外の他の実施例として、図２に示すように、容器の口部３とチューブ容器の口部２が一体成形で製造され、そのチューブ容器の口部２に、球体６を収納するための球体収納部５が形成されたものであってもよい。
【００１６】
この発明の特徴は、図７〜図１０に示すように、内容物が流出するノズル部９の先端部１０の外形形状を、半径方向に膨出するように形成すると共に、先端部１０の外径Ｔを、連続するノズル下部の絞部１１の径Ｓより大きく形成したものである。具体的には、図７〜図１０に示すように、ノズル部９の先端部１０から、ノズル下部の絞部１１に至るノズル部９の先端部１０の外形形状が、途中に鋭角、又は図７に示すように直角（α）、又は図８及び図９に示すように鈍角（β）を有する鰓張部１２が形成された形状である。さらに図１０に示すように、ノズル部９の先端部１０から、ノズル下部の絞部１１に至るノズル部９の先端部１０の外形形状が、滑らかな曲線１４で連続している断面円形又は断面楕円形状であってもよい。
【００１７】
次に、この発明の特徴として、球体６が収納される球体収納部５の下止部７との間に、隙間５ａを形成したことを特徴としている。図４に示すように、球体６を止める下止部７の突出部７ａが、球体収納部５の全周囲に少なくとも１ケ所以上形成されている。図５に示すように、球体６と球体収納部５との間に、突出部７ａを介して隙間５ａが形成されると、これにより内容物の絞り出し直後、チューブ容器１内に若干のエアーバックが行われる。隙間を設ける方法として、突出部７ａに代えて、下止部７に溝を設けてもよい（図示せず）。また、図６に示すように、下止部７に突出部７ａが全く形成されない場合は、球体６が球体収納部５の下止部７に完全に密接するので、この場合はエアーバックしないので、逆止弁としての機能を有する。　さらに、この発明の特徴は、球体６の球体収納部５内を移動する移動距離が、従来と比較すると、小さく形成されている点にある。図１に示すように寸法Ｘ＝０．２〜０．３ｍｍ程度である。従来は、図１２に示すように、移動距離Ｙ＝０．７〜１．４程度であった。このように球体の移動距離を小さくすることにより、内容物の突発的な抽出を防止することができることを発明者は見い出した。
【００１８】
図１１〜図１４は、この発明に係る容器の口部の第２実施の態様を示すもので、夫々エアゾール容器２１、３１、４１のバルブ２２、３２、４２に、容器の口部２３、３３、４３が連結された実施の形態を示した図面である。図１１に示すように、容器の口部２３、３３、４３の押圧部２３ａ、３３ａ、４３ａを、夫々容器方向（図１１の矢印方向）に指で押圧することにより、夫々のエアゾール容器２１、３１、４１のバルブ２２、３２、４２を開状態にでき、内容物２５、３５、４５を外部へ取り出すことができる。図１１及び図１２は、エアゾール容器２１内に内筒２４を設け、この内筒２４の底部を、エアゾール容器２１の底部内面に当接した小型の二重エアゾール容器に適用したものである。又、図１３は、内容物３５とプロペラントが混合して充填されたカール部を有するエアゾール容器３１に適用したものである。さらに、図１４は、カール部を有するエアゾール容器４１内に、内筒４４を懸吊した状態を示す二重エアゾール容器４１に適用したものである。これらの容器の口部２３、３３、４３には夫々キャップ２８、３８、４８が被せてある。なお、第３実施の形態として、図１５に示すように、この発明に係る容器の口部５３を、樹脂製等のボトル容器５１の口部５２に適用できることはいうまでもない。
【００１９】
次に、この発明の作用について説明する。
この発明に係る第１実施の形態は、容器の口部３のノズル部９の先端部１０から、ノズル下部の絞部１１に至るノズル部９の外形形状が、図７〜図１０に示すように、途中に鋭角、直角（α）又は鈍角（β）を有する鰓張部１２が形成されたものであるから、図３に示すように、チューブ容器１を横にして、内容物を抽出する場合、内容物はノズル部９の先端部１０から、先端部１０の表面を伝って、この鰓張部１２先端に到達したとき、表面を伝う内容物の水滴の表面張力が、自重に負けて確実に落下する。したがって、それ以後連続的に先端部１０の表面を伝うのを阻止することができる。また、この発明は、球体６と、この球体６が収納される球体収納部５の下止部７との間に隙間５ａを形成したので、この隙間５ａを通じて若干のエアーバック現象が生じるため、チューブ容器１内にエアーが流入する。そして、チューブ容器１の胴部が膨らむので、次回の内容物の押し出し操作が容易となる。さらに、球体６が球体収納部５内を移動する距離が小さいので、内容物の突発的な抽出が防止される。又、球体収納部５の内周面又は球体６の表面に、少なくとも１本以上の縦溝又はしぼ加工を施した場合には、チューブ容器１の押圧操作により、縦溝またはシボ加工の粗さの隙間を内容物が通過することにより、適量の内容物が滴下される。また押圧操作解除により球体６が移動するので、内容物は切れ良くチューブ容器１内に吸い上げられる。
【００２０】
次に、第２実施の形態に係るエアゾール容器２１、３１、４１に、この発明に係る容器の口部２３、３３、４３を適用すれば、上記チューブ容器１と同様の作用により、内容物２５、３５、４５が、ノズル部２９、３９、４９の先端部２０、３０、４０の表面を伝うのを阻止することができ、エアゾール容器内の内容物を有効に滴下させることができる。エアゾール容器内の内容物２５、３５、４５としては、チューブ容器１と同様に、水虫薬、オイル類、クリーム類等を充填することができる。
さらに、第３実施の態様のボトル容器５１の口部５２に適用することにより、同様の作用を呈する。
【００２１】
【発明の効果】
以上説明してきたように、この発明によれば、内容物を裏もれさせることなく、内容物の抽出が良好であるという効果がある。また内容物を突発的に抽出するのを防止することができると共に、縦溝またはシボ加工により、内容物を滴下状態で滴下させることができる効果を有する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mouth portion of a container, and more particularly, to a mouth portion of a container that can be dripped sharply from a nozzle portion without causing the contents to leak.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 16 and 17, there is a tube container having a sphere 105 in a sphere storage portion 103 of an inner plug body 102 that is fitted to an opening 101 of a tube container body 100. A tube container having a desired dropping function has a sphere in which at least one or more vertical grooves 104 are formed on the surface of the sphere storage portion 103. The reason why the spherical body 105 is provided is to prevent air bag after extracting the contents, and to form the vertical groove 104 is to drop and extract the contents little by little.
[0003]
[Problems to be solved by the invention]
However, such a tube container has the following disadvantages.
(1) Since the shape of the nozzle 106 has a shape in which the outer diameter gradually becomes smaller as it goes to the tip portion, as shown in FIG. There is a drawback in that a so-called back leakage phenomenon that occurs on the outer peripheral surface of the nozzle portion 106 occurs.
(2) After the contents are extracted, since there is no gap between the sphere 105 and the lower stopper 107 of the sphere storage part 103 in which the sphere 105 is stored in order to completely prevent airbags, After the object is extracted, no air bag is generated, so that the body of the tube container body 100 remains in a concave state. Therefore, there is a disadvantage that the next squeezing operation becomes extremely difficult.
(3) Since the moving distance Y of the sphere 105 moving in the sphere storage unit 103 is large (Y = 0.7 to 1.4), there is a disadvantage that contents are suddenly extracted.
[0004]
The present invention has been made in view of such a conventional problem, and it is possible to drop the contents sharply from the nozzle portion without causing the contents to be overturned, to perform a good squeezing operation, and to suddenly cause the contents to suddenly occur. An object of the present invention is to provide a mouth portion of a container, which is prevented from being extracted.
[0005]
[Means for Solving the Problems]
In order to solve this problem, a means corresponding to the first aspect of the present invention is to increase the outer shape of the tip of the nozzle from which the contents flow out at the mouth of the container having a sphere at the mouth in the radial direction. A mouth portion of the container characterized in that it is formed so as to protrude and the outer diameter of the tip portion is formed to be larger than the diameter of the constricted portion below the continuous nozzle.
[0006]
The means corresponding to the invention described in claim 2 is that the outer shape of the nozzle portion from the tip of the nozzle portion to the lower portion of the nozzle is a shape in which a gill stretch portion having an acute angle, a right angle or an obtuse angle is formed in the middle. The mouth of a container characterized by the following.
[0007]
According to a third aspect of the present invention, there is provided a mouth portion of the container, wherein the outer shape of the nozzle portion from the tip portion of the nozzle portion to the lower portion of the nozzle is continuous with a smooth curve.
[0008]
According to a fourth aspect of the present invention, there is provided a container mouth portion, wherein a gap is formed between the spherical body and a bottom stop portion of the spherical body storage portion with which the spherical body contacts.
[0009]
According to a fifth aspect of the present invention, there is provided an opening portion of the container, wherein the sphere has a small moving distance for moving the sphere storing section.
[0010]
According to a sixth aspect of the present invention, there is provided a container mouth, wherein at least one vertical groove or grain is formed on the inner peripheral surface of the sphere storage portion or the surface of the sphere.
[0011]
The means corresponding to the invention described in claim 7 is a mouth part of the container, which is fitted or integrated with the mouth part of the tube container.
[0012]
The means corresponding to the invention described in claim 8 is a mouth of the container, which is fitted or integrated with the mouth of the bottle container.
[0013]
According to a ninth aspect of the present invention, there is provided a container mouth, wherein the mouth of the container is connected to a valve of the aerosol container.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
1 to 10 are drawings showing a tube having a sphere according to the present invention, and FIGS. 1 and 3 are drawings showing a first embodiment according to the present invention. The tube container 1 is a conventionally known single-layer, multi-layer or laminate tube container. As shown in FIG. 1, the mouth 3 of the container is fitted into the mouth 2 of the tube container. A passage 4 is formed above the mouth portion 3 of the container, and a sphere storage portion 5 having an enlarged inner diameter is formed continuously below the passage 4. The inner diameter of the sphere housing portion 5 is configured to be slightly larger than the diameter of the sphere 6, and below the sphere housing portion 5, a lower stop 7 formed slightly smaller than the diameter of the sphere 6 expands inward in the radial direction. It is formed out. When the sphere 6 is supported by the lower stop 7 and the sphere 6 comes into close contact with the lower stop 7, a check valve function is exerted by the interaction between the lower stop 7 and the sphere 6, and the sphere 6 comes into close contact. Otherwise, it has a slight airbag effect. That is, as shown in FIGS. 4 and 5, there are a case where the protrusion 7 a is formed on the lower stopper 7 and a case where the protrusion 7 a is not formed as shown in FIG. 6. The sphere 6 is forcibly inserted into the sphere housing 5 from below the lower stop 7.
[0015]
In the first embodiment, at least one or more vertical grooves 8 are formed on the inner peripheral surface of the sphere housing portion 5 as necessary. By the formation of the vertical groove 8, the drop amount of the content extracted at one time can be determined. The width, groove depth, and number of the vertical grooves 8 can be freely determined according to the viscosity of the contents. For example, when the protruding portion 7a is formed by one vertical groove, it is suitable as a low-viscosity content, for example, when the content is an athlete's foot or the like. Further, when the protrusion 7a is formed by three vertical grooves, it is suitable for a high-viscosity content such as an oil or a cream. Furthermore, when the three vertical grooves do not form the protruding portion 7a, the content is a high-viscosity content, and is suitable for a content that must not be exposed to air. In addition, instead of the vertical grooves 8, the inner peripheral surface of the sphere housing portion 5 or the surface of the sphere 6 may be subjected to graining. Similarly, the depth of the graining can be appropriately determined in accordance with the viscosity of the content, the amount of one drop of the content, and the like. For example, when the viscosity of the content is low, the maximum depth can be determined arbitrarily, such as about 14 μm, and when the viscosity of the content is high, the maximum depth can be determined at about 80 μm. As another embodiment other than the type in which the mouth 3 of the container is fitted to the mouth 2 of the tube container, as shown in FIG. 2, the mouth 3 of the container and the mouth 2 of the tube container are integrally formed. It may be manufactured, and the sphere storage part 5 for storing the sphere 6 may be formed in the mouth part 2 of the tube container.
[0016]
The feature of the present invention is that, as shown in FIGS. 7 to 10, the outer shape of the tip portion 10 of the nozzle portion 9 from which the contents flow out is formed so as to bulge in the radial direction, and the outer shape of the tip portion 10 is increased. The diameter T is formed to be larger than the diameter S of the constricted portion 11 below the continuous nozzle. Specifically, as shown in FIGS. 7 to 10, the outer shape of the distal end portion 10 of the nozzle portion 9 from the distal end portion 10 of the nozzle portion 9 to the throttle portion 11 under the nozzle has an acute angle or 7 and a gill stretch 12 having a right angle (α) or an obtuse angle (β) as shown in FIGS. 8 and 9. Further, as shown in FIG. 10, the outer shape of the distal end portion 10 of the nozzle portion 9 from the distal end portion 10 of the nozzle portion 9 to the throttle portion 11 under the nozzle has a circular or cross-sectional shape in which a smooth curve 14 continues. It may be elliptical.
[0017]
Next, as a feature of the present invention, a gap 5a is formed between the sphere storage portion 5 and the lower stopper 7 in which the sphere 6 is stored. As shown in FIG. 4, at least one or more protrusions 7 a of the lower stopper 7 for stopping the sphere 6 are formed around the entire sphere housing 5. As shown in FIG. 5, when a gap 5a is formed between the sphere 6 and the sphere storage section 5 via the protruding portion 7a, a slight air bag is placed in the tube container 1 immediately after the contents are squeezed out. Is performed. As a method of providing a gap, a groove may be provided in the lower stopper 7 instead of the protrusion 7a (not shown). In addition, as shown in FIG. 6, when the protrusion 7a is not formed at all in the lower stopper 7, the sphere 6 is completely in close contact with the lower stopper 7 of the sphere housing 5, and in this case, no airbag is performed. , Has a function as a check valve. Further, a feature of the present invention is that the moving distance of the sphere 6 moving in the sphere housing portion 5 is smaller than that of the related art. As shown in FIG. 1, the dimension X is about 0.2 to 0.3 mm. Conventionally, as shown in FIG. 12, the moving distance Y was about 0.7 to 1.4. The inventor has found that by reducing the moving distance of the sphere in this way, sudden extraction of the contents can be prevented.
[0018]
11 to 14 show a second embodiment of the mouth portion of the container according to the present invention. The valves 22, 32, and 42 of the aerosol containers 21, 31, 41 are respectively connected to the mouth portions 23, 33 of the container. And FIG. 43 are drawings showing an embodiment in which they are connected. As shown in FIG. 11, the pressing portions 23a, 33a, 43a of the mouth portions 23, 33, 43 of the containers are pressed by fingers in the container directions (arrow directions in FIG. 11), respectively, so that the respective aerosol containers 21, The valves 22, 32, 42 of the 31, 31 can be opened, and the contents 25, 35, 45 can be taken out. 11 and 12 show an example in which an inner cylinder 24 is provided in an aerosol container 21, and the bottom of the inner cylinder 24 is applied to a small double aerosol container in contact with the inner surface of the bottom of the aerosol container 21. FIG. 13 shows an aerosol container 31 having a curl portion filled with a mixture of contents 35 and a propellant. Further, FIG. 14 shows an application to a double aerosol container 41 showing a state in which an inner cylinder 44 is suspended in an aerosol container 41 having a curled portion. The caps 28, 38, and 48 are placed over the mouths 23, 33, and 43 of these containers, respectively. As a third embodiment, as shown in FIG. 15, it goes without saying that the mouth 53 of the container according to the present invention can be applied to the mouth 52 of a bottle container 51 made of resin or the like.
[0019]
Next, the operation of the present invention will be described.
In the first embodiment according to the present invention, the outer shape of the nozzle portion 9 extending from the tip portion 10 of the nozzle portion 9 of the mouth portion 3 of the container to the throttle portion 11 at the lower portion of the nozzle is as shown in FIGS. Since a gill stretch 12 having an acute angle, a right angle (α), or an obtuse angle (β) is formed on the way, the tube container 1 is placed sideways to extract the contents as shown in FIG. In this case, when the content travels from the distal end portion 10 of the nozzle portion 9 to the tip of the gill extension portion 12 through the surface of the distal end portion 10, the surface tension of the water droplet of the content traveling on the surface loses its own weight. Drops reliably. Therefore, it is possible to prevent the tip portion 10 from continuously traveling on the surface thereafter. Further, according to the present invention, since the gap 5a is formed between the spherical body 6 and the lower stopper 7 of the spherical body housing portion 5 in which the spherical body 6 is housed, a slight airbag phenomenon occurs through the gap 5a. Air flows into the tube container 1. And since the trunk | drum of the tube container 1 expands, the pushing-out operation of the content next time becomes easy. Furthermore, since the distance by which the sphere 6 moves in the sphere storage unit 5 is small, sudden extraction of the contents is prevented. When at least one vertical groove or grain is formed on the inner peripheral surface of the spherical container 5 or on the surface of the spherical body 6, the pressing operation of the tube container 1 causes the roughness of the vertical groove or the grain to be processed. When the contents pass through the gap, an appropriate amount of the contents is dropped. Further, since the spherical body 6 is moved by releasing the pressing operation, the contents are sharply sucked into the tube container 1.
[0020]
Next, if the mouth portions 23, 33, and 43 of the container according to the present invention are applied to the aerosol containers 21, 31, and 41 according to the second embodiment, the contents 25 can be obtained by the same operation as that of the tube container 1. , 35, 45 can be prevented from traveling along the surfaces of the tips 20, 30, 40 of the nozzles 29, 39, 49, and the contents in the aerosol container can be effectively dripped. The contents 25, 35, and 45 in the aerosol container can be filled with athlete's foot medicine, oils, creams, and the like, similarly to the tube container 1.
Further, by applying the present invention to the mouth 52 of the bottle container 51 of the third embodiment, a similar effect is exhibited.
[0021]
【The invention's effect】
As described above, according to the present invention, there is an effect that the contents can be easily extracted without overlooking the contents. In addition, it is possible to prevent the contents from being suddenly extracted, and to have the effect that the contents can be dripped in a dripping state by vertical grooves or embossing.
