【発明の属する技術分野】
本発明は圧搾可能な筒状胴部を有するチューブ容器に関する。
【０００２】
【従来の技術】
例えば実開平４−１０６２４０号には、圧搾可能な筒状胴部を有し、かつ容器体口頸部上端内面へ上部小径の注出弁座を形成した軟質の容器体と、キャップ内側周壁を容器体口頸部外面へ螺合自在とすると共に、キャップ頂壁下面に、注出弁座内面へ嵌合自在な弁体と該弁体の注出弁座への嵌合時に口頸部上端に当接する短筒とを形成したキャップとを有し、キャップ取外し状態での胴部圧搾により注出弁座から容器体内容物を注出させると共に、容器体口頸部へのキャップの螺合により弁体を注出弁座内面へ嵌合させて容器体内容物の漏洩防止を図るチューブ容器が開示されている。
【０００３】
【発明が解決しようとする課題】
この種のチューブ容器では、キャップを容器体口頸部外面へ螺合させてねじ込んだ際、弁体が注出弁座から弁座上方へ離隔して注出弁座内面へ完全に嵌合することなく弁体外面と注出弁座内面との間に隙間が生じていると、この隙間から容器体内容物が漏洩し、口頸部上端と短筒との間の間隙を通って容器体口頸部外面とキャップ内側周壁内面との間から外部へ漏出するため、キャップねじ込みを完全にする必要があるが、このねじ込みが完全であるか否かを確認する手段がないため、キャップねじ込みが不完全であったり、あるいは必要以上にねじ込んだりすることがあった。
【０００４】
請求項１記載のチューブ容器は、注出口と弁体との嵌合時に変形惹起突起に係合して弾性変形し、該弾性変形突起乗越えによる係合解除により復帰音を発して元の形状に戻る弾性片を形成し、注出口に弁体が嵌合した時にこれを知らせる確認音を出させるようにして両者の嵌合を音響表示させることにより注出口と弁体との嵌合を外部から認識可能とし、開閉キャップの不完全なねじ込みや必要以上のねじ込み防止を図ろうとするものである。
【０００５】
【課題を解決するための手段】
第１の手段として、上端部に弁体６を有する弁柱５を容器体口頸部２内に立設し、該弁柱外面と口頸部内面との間に注出路７ａを形成すると共に、口頸部下部外面に突出部３を形成した軟質の容器体Ａと、
口頸部外面へ回動不能に嵌合させた硬質の装着筒Ｂと、
キャップ周壁を装着筒外面へ螺合させ、かつキャップ頂壁に、弁体６外面へ嵌合自在な注出口１２と該注出口の弁体６外面への嵌合時に口頸部上端に当接する当接面１４とを形成すると共に、キャップ周壁下端に、注出口１２が弁体６から弁体上方へ所定距離だけ離隔した際に口頸部下部の突出部３に係合する係合突部３ａを形成した硬質の開閉キャップＣとを有し、
上記装着筒Ｂ外面とキャップ周壁内面とのいずれか一方に変形惹起突起１３を形成すると共に、他方に、開閉キャップねじ込み回動による注出口１２と弁体６との嵌合時に変形惹起突起１３に係合して弾性変形し、変形惹起突起乗越えによる係合解除により復帰音を発して元の形状に戻る弾性片９を形成した。
【０００６】
【発明の実施の形態】
以下、本発明に係るチューブ容器の実施形態を図面を参照しながら説明する。
本発明に係るチューブ容器は、容器体Ａ、装着筒Ｂ、及び開閉キャップＣを主たる構成要素とする。以下、これらについて順次説明する。
【０００７】
図１においてＡはポリエチレン等の軟質の合成樹脂材から形成した容器体で、圧搾可能な筒状の胴部１上端から第１内向きフランジを介して口頸部２を起立している。
口頸部２は第１内向きフランジ内端から起立した大径筒と、大径筒上端から第２内向きフランジを介して起立した小径筒とを有している。そして、大径筒上端外面に後述する開閉キャップＣのキャップ周壁下端が係合自在な突出部３を周設している。
【０００８】
また、小径筒下部外面に、後述する装着筒Ｂ下部内面へ係合自在な突起を周設すると共に、図２にも示すように、該突起よりも上方の小径筒筒壁外面に上下に伸びる内側回り止め突条４を周方向に所定の間隔をおいて多数縦設している。
【０００９】
さらに、小径筒内面の上下方向中間部から第３内向きフランジを突設し、該第３内向きフランジ内端から弁柱５を立設し、該弁柱５の上端を縮径して小径筒上方に突出する弁体６を形成し、さらに、該第３内向きフランジに通孔７を周方向に所定の間隔をおいて複数穿設し、弁柱５及び弁体６外面と小径筒上部内面との間に注出路７ａを形成している。
【００１０】
Ｂはポリプロピレン等の硬質の合成樹脂材から形成した装着筒で、口頸部２の小径筒外面へ回動不能に嵌合させている。すなわち、装着筒Ｂは内面下部に溝部を周設すると共に、上端を縮径して縮径部を形成し、さらに図２にも示すように、溝部と縮径部との間の装着筒筒壁内面に上下に伸びる外側回り止め突条８を周方向に所定の間隔をおいて多数縦設し、溝部に、小径筒下部外面に周設した突起を係合させると共に、外側回り止め突条８に、内側回り止め突条４を係合させ、さらに縮径部内面を小径筒上端外面へ接面させている。
【００１１】
さらに、装着筒Ｂは縮径部外面に径方向に突出する板状の弾性片９を突設している。該弾性片９はその基部を支点にして周方向に弾性変形自在で、弾性変形後、元の形状に戻る際にパチッという復帰音を発する。さらに、装着筒Ｂはその上下方向中間部外面に雄ねじ１０を形成している。
【００１２】
Ｃはポリプロピレン等の硬質の合成樹脂材から形成した開閉キャップで、キャップ周壁上部内面に雌ねじ１１を形成し、該雌ねじ１１を雄ねじ１０へ螺合させると共に、キャップ周壁下端内面に周設した係合突部３ａを突出部３に係合可能としている。
【００１３】
また、キャップ周壁の上面を閉塞するキャップ頂壁の中央部に注出口１２を形成している。該注出口１２は、開閉キャップＣのねじ込み方向への回動により所定距離だけ下方変位すると弁体６外面へ嵌合して注出路７ａを閉塞すると共に、上記と反対方向への開閉キャップＣの回動により弁体６上方へ変位して該弁体６から離隔する。
【００１４】
さらに、開閉キャップＣはキャップ周壁上端内面に変形惹起突起１３を突設している。変形惹起突起１３下端面の径方向側辺は、注出口１２が下方変位してその下端面が弁体６の上端面上に達したところで、或いはその前後において弾性片９上端面の径方向側辺の先端部に隣接する。そして、注出口１２がさらに下方変位して弁体６外面への嵌合を開始すると、これと共に変形惹起突起１３も下方変位してその側面と先端面とが交差する角部１３ａが弾性片９の側面に係合する。すると弾性片９はその基部を支点にして開閉キャップＣの回動方向に弾性変形を始め、ある程度変形すると弾性片９の先端面と側面とが交差する角部９ａが変形惹起突起１３の先端面上を摺動する。そして、図３に示すように、注出口１２が弁体６外面へ完全に嵌合して注出口１２の上端面が弁体６の上端面上に達したところで弾性片９は変形惹起突起１３を乗り越え復帰音を発して元の形状に戻る。
【００１５】
弾性片９は上記したようにその角部９ａが変形惹起突起１３の先端面上を摺動するため、摩擦力軽減を考慮してその摺動面積はできるだけ小さい方が望ましく、かかる観点から弾性片９の上端面と先端面とが交差する角部は図示例のように切除するのが好ましい。
【００１６】
さらに、開閉キャップＣはキャップ頂壁外周部下面に、注出口１２が弁体６外面へ完全に嵌合した際に、口頸部２と装着筒Ｂとのそれぞれの上端面に当接する当接面１４を形成している。このようにキャップ頂壁が少なくとも口頸部２上端面に当接することにより、容器体内容物の漏洩がより完全に防止される。
【００１７】
なお、上記では弾性片９を装着筒Ｂに形成し、変形惹起突起１３を開閉キャップＣに形成したが、これに限らず弾性片９をキャップ周壁上端内面に、また変形惹起突起１３を装着筒Ｂ上端外面に形成してもよく、この場合においても上記と同一の作用・効果が得られる。
【００１８】
１５はキャップ頂壁の内周部下面から垂下した案内筒で、その外面は口頸部２上端部内面へ上下動自在にかつ回動自在に嵌合している。該案内筒１５は、開閉キャップＣの回動による上下動を円滑ならしめるという観点から好ましい形態として形成している。
【００１９】
次に本実施形態の作用について説明する。
図１は開口状態にある容器体口頸部を示すもので、この状態で胴部１を圧搾すると内容物は通孔７を通り注出路７ａを経て注出口１２から外部に押し出される。容器体口頸部２を閉塞するには、図１に示す状態から開閉キャップＣを回動させてねじ込めばよく、すると上記したように変形惹起突起１３が弾性片９に係合してこれを弾性変形させる。そして、注出口１２全体が弁体６外面へ完全に嵌合するのとほぼ同時に弾性片９が変形惹起突起１３を乗り越え復帰音を発して元の形状に戻る。
【００２０】
注出口１２が弁体６へ完全に嵌合した時点で注出路７ａは完全に閉塞されており、しかもキャップ頂壁の当接面１４が口頸部２上端面へ当接しているため、内容物が外部に漏洩することがない。
【００２１】
容器体口頸部２を開口するには、開閉キャップＣを上記と反対方向に回動すればよく、すると注出口１２は弁体６上方へ変位して弁体６から離隔し、そして弁体６から所定距離だけ離隔したところで、キャップ周壁下端の係合突部３ａが突出部３に係合する。
【００２２】
【発明の効果】
請求項１記載のチューブ容器は、軟質の容器体の口頸部外面へ硬質の装着筒を嵌合させ、硬質の開閉キャップ又は装着筒の一方に変形惹起突起を形成すると共に、他方に、開閉キャップの注出口と容器体の弁体との嵌合時に変形惹起突起に係合して弾性変形し、該弾性変形突起乗越えによる係合解除により復帰音を発して元の形状に戻る弾性片を形成したので、容器体が軟質であるにもかかわらず開閉キャップの注出口に容器体の弁体が嵌合した時にこれを知らせる確認音の発生が可能となって両者の嵌合が音響表示されるため、注出口と弁体との嵌合が外部から認識可能となり、したがって開閉キャップの不完全なねじ込みや必要以上のねじ込みが防止される。

[Problems to be solved by the invention]
In this type of tube container, when the cap is screwed onto the outer surface of the mouth and neck of the container body, the valve body is separated from the pouring valve seat above the valve seat and completely fits into the pouring valve seat inner surface. If there is a gap between the outer surface of the valve body and the inner surface of the dispensing valve seat, the contents of the container body leak from this gap, and the container body passes through the gap between the upper end of the mouth neck and the short tube. Since it leaks to the outside from between the outer surface of the mouth and neck and the inner surface of the inner wall of the cap, it is necessary to completely screw the cap, but since there is no means to check whether this screwing is complete, Sometimes it was incomplete or screwed more than necessary.
[0004]
The tube container according to claim 1 is elastically deformed by being engaged with the deformation-inducing protrusion when the spout and the valve body are fitted, and a return sound is generated by releasing the engagement by getting over the elastic deformation protrusion to return to the original shape. A return elastic piece is formed, and when the valve body is fitted to the spout, a confirmation sound is sent to inform the user of this, and the fitting between the spout and the valve body is externally indicated by an acoustic display. It is designed to be able to recognize and to prevent incomplete screwing of the open / close cap and unnecessarily screwing.
[0005]
[Means for Solving the Problems]
As a first means, a valve column 5 having a valve body 6 at the upper end is erected in the container body neck portion 2, and an extraction passage 7a is formed between the outer surface of the valve column and the inner surface of the mouth neck portion. A soft container A having a protrusion 3 formed on the outer surface of the lower part of the mouth and neck,
A rigid mounting cylinder B fitted non-rotatably to the outer surface of the mouth and neck,
The cap peripheral wall is screwed onto the outer surface of the mounting cylinder, and the cap top wall abuts the spout 12 that can be fitted to the outer surface of the valve body 6 and the upper end of the mouth neck when the spout is fitted to the outer surface of the valve body 6. And an engaging protrusion that engages with the protrusion 3 at the bottom of the neck of the mouth and neck when the spout 12 is separated from the valve body 6 by a predetermined distance above the valve body at the lower end of the cap peripheral wall. 3a and a hard opening / closing cap C,
The deformation-inducing protrusion 13 is formed on either the outer surface of the mounting cylinder B or the inner surface of the cap peripheral wall, and on the other side, the deformation-inducing protrusion 13 is formed when the spout 12 and the valve body 6 are engaged with each other by screwing the opening / closing cap. An elastic piece 9 is formed which is elastically deformed by engagement and returns to its original shape by making a return sound by disengagement by overcoming the deformation-induced protrusion.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a tube container according to the present invention will be described with reference to the drawings.
The tube container according to the present invention includes a container body A, a mounting cylinder B, and an opening / closing cap C as main components. Hereinafter, these will be sequentially described.
[0007]
In FIG. 1, A is a container body formed from a soft synthetic resin material such as polyethylene, and the neck portion 2 is erected from the upper end of a squeezable cylindrical body portion 1 through a first inward flange.
The mouth-and-neck portion 2 has a large-diameter cylinder that stands from the inner end of the first inward flange and a small-diameter cylinder that stands from the upper end of the large-diameter cylinder via the second inward flange. And the protrusion part 3 which the cap peripheral wall lower end of the opening-and-closing cap C mentioned later can engage freely is provided in the large-diameter cylinder upper end outer surface.
[0008]
Further, a protrusion that can be engaged with the inner surface of the lower portion of the mounting cylinder B, which will be described later, is provided on the outer surface of the lower portion of the small-diameter cylinder, and extends vertically to the outer surface of the small-diameter cylinder tube wall above the protrusion as shown in FIG. A large number of inner detent ridges 4 are vertically provided at predetermined intervals in the circumferential direction.
[0009]
Further, a third inward flange protrudes from the middle in the vertical direction of the inner surface of the small diameter cylinder, the valve column 5 is erected from the inner end of the third inward flange, and the upper end of the valve column 5 is reduced in diameter to reduce the small diameter. A valve body 6 projecting upward from the cylinder is formed, and a plurality of through holes 7 are formed in the third inward flange at predetermined intervals in the circumferential direction so that the outer surfaces of the valve column 5 and the valve body 6 and a small diameter cylinder are formed. A pouring path 7a is formed between the upper inner surface.
[0010]
B is a mounting cylinder formed from a hard synthetic resin material such as polypropylene and is fitted to the outer surface of the small-diameter cylinder of the mouth-and-neck portion 2 so as not to rotate. That is, the mounting cylinder B has a groove portion provided in the lower portion of the inner surface, and the upper end is reduced in diameter to form a reduced diameter portion. Further, as shown in FIG. 2, the mounting cylinder cylinder between the groove portion and the reduced diameter portion is provided. A large number of outer non-rotating protrusions 8 extending vertically on the inner surface of the wall are vertically provided at predetermined intervals in the circumferential direction, and the protrusions provided on the outer surface of the lower part of the small-diameter cylinder are engaged with the grooves, and the outer detent protrusions are engaged. 8, the inner detent ridge 4 is engaged, and the inner surface of the reduced diameter portion is in contact with the outer surface of the upper end of the small diameter cylinder.
[0011]
Further, the mounting cylinder B is provided with a plate-like elastic piece 9 protruding in the radial direction on the outer surface of the reduced diameter portion. The elastic piece 9 is elastically deformable in the circumferential direction with its base as a fulcrum, and emits a clicking sound when returning to its original shape after elastic deformation. Furthermore, the mounting cylinder B has a male screw 10 formed on the outer surface of the intermediate portion in the vertical direction.
[0012]
C is an open / close cap formed of a hard synthetic resin material such as polypropylene. An internal thread 11 is formed on the upper inner surface of the cap peripheral wall, the female screw 11 is screwed to the male screw 10 and the engagement is provided around the lower end inner surface of the cap peripheral wall. The protrusion 3 a can be engaged with the protrusion 3.
[0013]
Moreover, the spout 12 is formed in the center part of the cap top wall which obstruct | occludes the upper surface of a cap surrounding wall. When the opening / closing cap C is displaced downward by a predetermined distance due to the rotation of the opening / closing cap C in the screwing direction, the outlet 12 is fitted to the outer surface of the valve body 6 to close the discharging passage 7a, and the opening / closing cap C in the direction opposite to the above is closed. The valve body 6 is displaced upward by rotation and is separated from the valve body 6.
[0014]
Further, the opening / closing cap C is provided with a deformation-inducing projection 13 on the inner surface of the upper end of the cap peripheral wall. The radial side of the lower end surface of the deformation-inducing projection 13 is the radial side of the upper end surface of the elastic piece 9 when the spout 12 is displaced downward and the lower end surface reaches the upper end surface of the valve body 6 or before and after. Adjacent to the tip of the side. When the spout 12 is further displaced downward and starts fitting to the outer surface of the valve body 6, the deformation-inducing protrusion 13 is also displaced downward at this time, and the corner 13 a where the side surface and the tip surface intersect is formed by the elastic piece 9. Engage with the sides. Then, the elastic piece 9 starts to be elastically deformed in the rotational direction of the opening / closing cap C with the base portion as a fulcrum, and when the elastic piece 9 is deformed to some extent, the corner portion 9a where the front end surface and the side surface of the elastic piece 9 intersect is the front end surface of the deformation-inducing protrusion 13. Slide on the top. Then, as shown in FIG. 3, the elastic piece 9 is deformed to cause deformation 13 when the spout 12 is completely fitted to the outer surface of the valve body 6 and the upper end surface of the spout 12 reaches the upper end surface of the valve body 6. Get over and return to the original shape.
[0015]
As described above, since the corner portion 9a of the elastic piece 9 slides on the tip surface of the deformation-inducing protrusion 13, it is desirable that the sliding area be as small as possible in consideration of reducing the frictional force. It is preferable to cut off a corner portion where the upper end surface and the front end surface of 9 intersect as shown in the illustrated example.
[0016]
Further, the opening / closing cap C is in contact with the lower surface of the outer peripheral portion of the top wall of the cap and contacts the upper end surfaces of the neck 2 and the mounting cylinder B when the spout 12 is completely fitted to the outer surface of the valve body 6. A surface 14 is formed. As described above, the cap top wall abuts at least the upper end surface of the mouth-neck portion 2, thereby preventing the leakage of the container contents more completely.
[0017]
In the above description, the elastic piece 9 is formed on the mounting cylinder B and the deformation-inducing protrusion 13 is formed on the opening / closing cap C. However, the elastic piece 9 is not limited to this, and the deformation-inducing protrusion 13 is provided on the inner surface of the cap peripheral wall. B may be formed on the outer surface of the upper end, and in this case, the same operation and effect as described above can be obtained.
[0018]
A guide cylinder 15 is suspended from the lower surface of the inner peripheral portion of the top wall of the cap. The outer surface of the guide tube 15 is fitted to the inner surface of the upper end of the mouth neck portion 2 so as to be movable up and down. The guide tube 15 is formed in a preferable form from the viewpoint of smoothing the vertical movement caused by the rotation of the opening / closing cap C.
[0019]
Next, the operation of this embodiment will be described.
FIG. 1 shows a container body neck in an open state. When the trunk 1 is squeezed in this state, the contents are pushed out through a through hole 7 and through a pouring passage 7a to the outside. To close the container body neck 2, the opening / closing cap C is rotated from the state shown in FIG. 1 and screwed in. Then, the deformation-inducing protrusion 13 engages with the elastic piece 9 as described above. Is elastically deformed. The elastic piece 9 gets over the deformation-inducing protrusion 13 and returns to its original shape almost at the same time as the entire spout 12 is completely fitted to the outer surface of the valve body 6.
[0020]
When the spout 12 is completely fitted to the valve body 6, the spout 7a is completely closed, and the abutment surface 14 of the cap top wall is in contact with the upper end surface of the mouth neck portion 2. Things do not leak outside.
[0021]
In order to open the container body neck 2, the opening / closing cap C may be rotated in the opposite direction, and the spout 12 is displaced upward from the valve body 6 to be separated from the valve body 6. The engagement protrusion 3 a at the lower end of the peripheral wall of the cap engages with the protrusion 3 when it is separated by a predetermined distance from 6.
[0022]
【The invention's effect】
The tube container according to claim 1 is configured such that a hard mounting cylinder is fitted to the outer surface of the mouth and neck of the soft container body, and a deformation inducing protrusion is formed on one of the hard opening / closing cap or the mounting cylinder, and An elastic piece that is elastically deformed by engaging with the deformation-causing protrusion when the cap outlet of the cap and the valve body of the container body are fitted, and that returns to its original shape by releasing a return sound by disengaging the elastic deformation protrusion. Since the container body is soft, it is possible to generate a confirmation sound when the valve body of the container body is fitted to the spout of the opening and closing cap, and the fitting of both is displayed acoustically. Therefore, the fitting between the spout and the valve body can be recognized from the outside, so that incomplete screwing of the opening / closing cap and screwing more than necessary are prevented.
