Description

【０００１】
【発明の属する技術分野】
本発明は、スリットバルブを備えたキャップに関し、各種内容物に対して内容物を吐出させる際の液切れを改善して内容物の付着、固化に起因したバルブの作動不良及び吐出孔周辺の汚れを有利に回避しようとするものである。
【０００２】
【従来の技術】
化粧料や洗顔料等を収納する容器は、内容物の適量吐出が可能でかつその吐出に際して良好な液切れを可能とするスリットタイプのバルブが使用されている。
【０００３】
スリットタイプのバルブは通常、十字状の切り込みが形成されており、容器の胴部を加圧して内圧を高め、バルブの中央域に設けたスリットを瞬時に開放させることにより内容物を適量吐出することができるようになっている。
【０００４】
ところで、従来のバルブは、内容物としてクリームのような粘度の高いものを用いる場合にはとくに問題はないものの、オイル系の化粧料や植物油等、比較的粘度の低いものを用いる場合では、内容物を吐出させた際の切れが悪いため、バルブの先端部分に内容物が付着してしまうのが避けられない。
【０００５】
そして、付着した内容物をそのままにしておくとそれが固化してしまいバルブの開放動作にしばしば悪影響を及ぼしたり、吐出孔周辺の汚れにつながる不具合があった。
【０００６】
【発明が解決しようとする課題】
本発明は、内容物の吐出に際して液切れのよい新規なスリットバルブ付きのキャップを提案するところにある。
【０００７】
【課題を解決するための手段】
本発明は、容器内に通じる開口を有するキャップ本体と、このキャップ本体の開口にバルブ押さえとの挟持下に固定保持され容器の傾動姿勢を保持しつつその胴部の加圧によりスリットを開放して容器内の内容物を適量吐出させるスリットバルブと、このスリットバルブを覆い隠しキャップ本体に着脱自在に保持される蓋体とを備え、
前記スリットは、互いに十字状に直交する切り込みの組合せからなり、
前記キャップ本体は、前記開口を形成する周壁の下端部が切り欠かれてなる凹部を有し、
前記バルブ押さえは、前記凹部に適合する凸部を有し、
前記スリットの切り込みの一方を容器を傾動させる向きに合致させてなることを特徴とするスリットバルブ付きキャップである。
【０００８】
【発明の実施の形態】
以下、図面を参照して本発明をより具体的に説明する。
図１に本発明に従うスリットバルブを備えたキャップを円筒状の胴部を有する容器に適用した構成例を示す。
【０００９】
図１において番号１は容器、２は容器１の口部に装着されたキャップである。
【００１０】
キャップ２は図２（ａ）（ｂ）にその平面及び断面をそれぞれ示したように、容器１内に通じる開口Ｏを有し、容器１の口部においてねじ止めすることができるキャップ本体２ａと、キャップ本体２ａの開口Ｏに配置されバルブ押さえ３との挟持下に固定保持されるスリットバルブ２ｂと、スリットバルブ２ｂを覆い隠しキャップ本体２ａに着脱自在に保持されるヒンジタイプを例とした蓋体２ｃからなっている。
【００１１】
スリットバルブ２ｂはその先端部分に、容器を傾動させる向き（Ｘ）に沿う切り込みＳとこの切り込みＳに直交する切り込みＳ１との組み合わせになる十字状のスリットが形成されている。
【００１２】
通常、この種のキャップは、キャップ本体へのバルブの取り付けに際して厳密な位置決め管理がなされておらず、図３に示すような状態にて組み込まれることもあり、このような状態で内容物を吐出させると、内容物によっては液切れがよくないために図４に示すようにバルブの先端部分に内容物が付着することもあって、これがバルブの開放動作を阻害したり、吐出孔周辺を汚してしまう要因にもなっていたわけである。
【００１３】
本発明に従うキャップは、スリットの切り込みＳについて、容器を傾動させる向き（Ｘ）に合致しているため、バルブが開放動作から閉塞動作に移行する際、バルブ先端部分に存在する内容物を容器内へと吸い込むようになるため粘度の低い内容物であっても液切れがよい。
【００１４】
キャップ本体２ａにスリットバルブ２ｂを取り付けるに際してスリットＳの位置合わせを行なうには、図５（ａ）（ｂ）に示すように、バルブ押さえ３に予め凸部３ａを設けておき、このバルブ押さえ３を保持するキャップ本体２ａには該凸部３ａに適合する凹部ｈを設けておく。そして、バルブ押さえ３の凸部３ａをキャップ本体２ａの凹部ｈに適合させたときに、バルブ２ｂの切り込みＳが容器の傾動する向きに合致するようスリットバルブ２ａとバルブ押さえ３とを予め位置決めしておく。
【００１５】
上掲図１に示したように、ヒンジタイプの蓋体２ｃを備えたキャップは蓋体２ｃが上方になるように容器を傾動させればその向き（Ｘ）とスリットの切り込みＳが一致するものであり、図４に示した状態で内容物が吐出することはない。
【００１６】
図６は胴部が偏平になるチューブタイプの容器に適用した例を示したものである。かかる容器に装着したキャップは蓋体２ｃがキャップ本体２ａから取り外すことができるものを適用しており、内容物の吐出に際して容器の幅広面が上下になるように容器を傾動させることを前提とした場合に、その向き（Ｘ）にスリットの切り込みＳが沿うようにキャップを装着するものであって、この容器についても、容器を傾動させる向き（Ｘ）とスリットの切り込みＳとが一致する限りにおいて液ぎれが改善される。
【００１７】
なお、図６に示すような容器は、容器の胴部につき、その幅狭面が上下になるように容器を傾動させるとき、その傾動する向きにスリットの切り込みＳ１が沿うこととなり、この場合も液ぎれが改善される。
【００１８】
容器を傾動させる向きは、蓋体（ヒンジタイプ）の取り付け位置や容器の胴部形状にて決定することができるが、その他、図示はしないが、キャップあるいは容器の胴部に容器を傾けるべき方向を示すマーク（例えば矢印等）を設けることにより内容物を吐出させるべき方向を表示することも可能である。
【００１９】
【発明の効果】
本発明によれば、内容物の粘度の高低の如何にかかかわらず液ぎれがよいので内容物の付着、固化によってバルブが作動不良を起こしたり、吐出孔周辺が汚れることがない。

BACKGROUND OF THE INVENTION
The present invention relates to a cap provided with a slit valve, which improves liquid breakage when discharging contents to various contents, and causes malfunction of the valve due to adhesion and solidification of the contents and contamination around the discharge holes. Is to be advantageously avoided.
[0002]
[Prior art]
As a container for storing cosmetics, face wash, etc., a slit-type valve is used that can discharge an appropriate amount of the contents and that can discharge well when discharged.
[0003]
A slit-type valve is usually formed with a cross-shaped cut, pressurizing the body of the container to increase the internal pressure, and instantaneously opening a slit provided in the central area of the valve to discharge an appropriate amount of content. Be able to.
[0004]
By the way, the conventional valve is not particularly problematic when using a high-viscosity content such as cream, but when using a relatively low-viscosity oil-based cosmetic or vegetable oil, Since the cut when the object is discharged is bad, it is inevitable that the contents adhere to the tip of the valve.
[0005]
If the attached contents are left as they are, they solidify and often have an adverse effect on the opening operation of the valve or lead to contamination around the discharge holes.
[0006]
[Problems to be solved by the invention]
The present invention proposes a novel cap with a slit valve that is excellent in running out of liquid when discharging contents.
[0007]
[Means for Solving the Problems]
The present invention has an open and a cap body having an opening communicating with the container, the slit by pressing the body portion while maintaining the tilted attitude of the container is fixed and held under clamping the valve retainer in the opening of the cap body A slit valve that discharges an appropriate amount of the contents in the container, and a lid that covers and covers the slit valve and is detachably held on the cap body,
The slit comprises a combination of cuts orthogonal to each other in a cross shape,
The cap body has a recess formed by cutting out a lower end portion of a peripheral wall forming the opening,
The valve retainer has a convex part that fits into the concave part,
The slit valve cap is characterized in that one of the slits is aligned with the direction in which the container is tilted .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows a configuration example in which a cap provided with a slit valve according to the present invention is applied to a container having a cylindrical body.
[0009]
In FIG. 1, reference numeral 1 is a container, and 2 is a cap attached to the mouth of the container 1.
[0010]
The cap 2 has an opening O leading to the inside of the container 1 as shown in FIGS. 2 (a) and 2 (b), and a cap body 2a that can be screwed at the mouth of the container 1. A slit valve 2b that is disposed in the opening O of the cap body 2a and is fixed and held under clamping with the valve presser 3, and a hinge type cover that covers the slit valve 2b and is detachably held by the cap body 2a. It consists of a body 2c.
[0011]
The slit valve 2b tip portion thereof, a cross-shaped slit comprising a combination of cuts S 1 perpendicular to the notch S of the S Toko cut along the direction (X) for tilting the container is formed.
[0012]
Normally, this type of cap is not subjected to strict positioning control when the valve is attached to the cap body, and may be incorporated in the state shown in FIG. 3, and the contents are discharged in such a state. As a result, depending on the contents, the liquid may not run out, and the contents may adhere to the tip of the valve as shown in FIG. 4, which hinders the opening operation of the valve or soils the periphery of the discharge hole. It was also a factor that ended up.
[0013]
Cap according to the invention, the notch S of the slit, since meets the orientation (X) where Ru is tilted the container, when the valve is shifted to the closing operation from the opening operation, the contents of which are present in the valve tip portion Even if it is a low-viscosity content, the liquid runs out because it is sucked into the container.
[0014]
In order to align the slit S when attaching the slit valve 2b to the cap body 2a, a convex portion 3a is provided in advance in the valve presser 3 as shown in FIGS. 5 (a) and 5 (b). The cap body 2a for holding the concave portion h is provided with a concave portion h that fits the convex portion 3a. Then, when the convex portion 3a of the valve presser 3 is fitted to the concave portion h of the cap body 2a, the slit valve 2a and the valve presser 3 are previously positioned so that the notch S of the valve 2b matches the tilting direction of the container. Keep it.
[0015]
As shown in FIG. 1 above, a cap provided with a hinge-type lid 2c is such that if the container is tilted so that the lid 2c is at the top, its orientation (X) and slit slit S match. Thus, the contents are not discharged in the state shown in FIG.
[0016]
FIG. 6 shows an example applied to a tube type container having a flat body. The cap attached to the container is such that the lid 2c can be removed from the cap main body 2a, and it is assumed that the container is tilted so that the wide surface of the container is up and down when the contents are discharged. In this case, the cap is mounted so that the slit notch S is along the direction (X), and the container is tilted as long as the direction (X) for tilting the container matches the slit notch S. Dripping is improved.
[0017]
In the case of the container as shown in FIG. 6, when the container is tilted so that the narrow surface is up and down with respect to the body of the container, the slit incision S 1 is along the tilting direction. The dripping is improved.
[0018]
The direction in which the container is tilted can be determined by the attachment position of the lid (hinge type) and the body shape of the container, but not shown, the direction in which the container should be tilted to the cap or the body of the container It is also possible to display the direction in which the contents are to be discharged by providing a mark (for example, an arrow or the like) that indicates.
[0019]
【The invention's effect】
According to the present invention, the liquid can be drained regardless of whether the content has high or low viscosity, so that the valve does not malfunction due to the adhesion and solidification of the content, and the periphery of the discharge hole is not contaminated.
