Description

本発明は、容器の口部にねじ止めして該容器を密封するのに好適な緩み止め機能を備えたキャップに関するものであり、該キャップの締め込み完了を明瞭なクリック感をもって把握させようとするものである。   The present invention relates to a cap having a loosening prevention function suitable for sealing the container by screwing it to the mouth of the container, and is intended to grasp the completion of tightening of the cap with a clear click feeling. To do.

化粧品、洗剤、食品、飲料等を入れるのに多用されているボトル、ジャー容器、チューブ容器等の各種容器では、容器の口部を密封する手段としてねじ込み式のキャップが使用されている。   In various containers such as bottles, jar containers, and tube containers that are frequently used for putting cosmetics, detergents, foods, beverages, and the like, screwed caps are used as means for sealing the mouth of the containers.

かかるキャップは、外部から負荷される不用意な力で簡単に緩むことがないように緩み止め機能を備えたものが存在しており、その具体的な構造としては、容器の口部の基端に突起と位置決め用の凹部を、また、キャップの内側壁の下端に該凹部に係合する凸部をそれぞれ設け、キャップの締め込みに際して該凸部が突起を乗り越え締め込み完了時点で該凸部が凹部に嵌まり込むものが知られている（例えば、特許文献１参照）。   Such caps have a function to prevent loosening so that they cannot be easily loosened by an inadvertent force applied from the outside. The specific structure of the cap is the base end of the mouth of the container. Protrusions and positioning recesses are provided on the inner wall of the cap, and protrusions that engage with the recesses are provided on the lower end of the inner wall of the cap. Is known that fits into a recess (for example, see Patent Document 1).

実公昭５９−１４３４２号公報Japanese Utility Model Publication No.59-14342

ところで、上記のような緩み止め機能を有する、とくに合成樹脂製のキャップは、使用開始当初はその機能が有効に発揮されるものの、使用頻度が高まるにつれ突起の先端が摩耗するため緩み止め効果が比較的早期のうちに劣化してしまう欠点を有していた。   By the way, the cap made of a synthetic resin having the above-mentioned locking function, particularly the synthetic resin cap, exhibits its function effectively at the beginning of use. It had the disadvantage of deteriorating relatively quickly.

また、この種のキャップは、その内側に容器の口部先端に当接して液密状態を保持するパッキンが配置されるが、該パッキンが口部先端に当接する時点とキャップの締め込みが完了する時点とが重なるためキャップに設けられた凸部が口部の基端の突起を乗り越える時に生じるクリック感が弾性体からなるシール部材に吸収されてしまうため明瞭でなく、キャップの締め込みに際して抜け止めがなされたかどうか確認しにくいところに問題を有していた。   In addition, this type of cap has a packing that contacts the tip of the mouth of the container and maintains a liquid-tight state on the inside of the cap. When the packing contacts the tip of the mouth, the cap is completely tightened. The click feeling that occurs when the convex part provided on the cap climbs over the protrusion at the base end of the mouth is absorbed by the sealing member made of an elastic material, so it is not clear, and it is not clear when the cap is tightened There was a problem where it was difficult to confirm whether or not the stop was made.

本発明の課題は、部材の局所的な摩耗を回避するとともに、締め込みの完了を明瞭に把握可能なクリック感を与えることができる新規なキャップを提案するところにある。   An object of the present invention is to propose a novel cap capable of avoiding local wear of a member and giving a click feeling capable of clearly grasping completion of tightening.

本発明は、内壁面にねじ部を有し容器の口部の回りを取り囲む環状側壁と、この環状側壁の上端に一体成形される天面壁とを備えたキャップであって、
前記キャップは、前記環状側壁の内側下端に設けられ容器の口部の基端に設けられた凸部を乗り越えることによって該キャップの緩みを防止する突起と、この突起が前記凸部を乗り越えた後において容器の口部先端に当接して該口部を液密状態に保持するシール部材とを備えることを特徴とするキャップである。 The present invention is a cap comprising an annular side wall having a threaded portion on the inner wall surface and surrounding the mouth of the container, and a top wall integrally formed at the upper end of the annular side wall,
The cap is provided with a protrusion provided on the inner lower end of the annular side wall and overcoming a protrusion provided at the base end of the mouth of the container, and after the protrusion has overcome the protrusion, the protrusion prevents the cap from loosening. And a sealing member that contacts the tip of the mouth of the container and holds the mouth in a liquid-tight state.

上記の構成になるキャップは、前記凸部及び突起の少なくとも一方が容器の口部の回りに沿って延びる環状体からなるものとするのが好ましい。   The cap configured as described above is preferably formed of an annular body in which at least one of the convex portion and the protrusion extends around the mouth of the container.

また、前記突起の凸部における乗り越えがクリック感を与えるものとすることができる。   Further, overcoming the protrusions of the protrusions can provide a click feeling.

キャップ側に設けられた突起が容器の口部の基端に設けられた凸部を乗り越えるまでとシール部材が容器の口部先端に当接するまでの間に時間差があるので、クリック感（突起乗り越え時の衝撃や打設音）が与えられ、キャップが抜け止めされたことが確実に把握できる。   There is a time difference between the protrusion provided on the cap side getting over the convex part provided at the base end of the container mouth and the seal member contacting the tip of the mouth of the container. Time and impact sound), it is possible to reliably grasp that the cap has been prevented from coming off.

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は本発明に従うキャップをマスカラを入れる容器に適用した実施の形態を示したものであり、図の左側半分はキャップの装着完了前の状態を、図面の右側半分はキャップの装着完了後の状態をそれぞれ示したものである。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows an embodiment in which a cap according to the present invention is applied to a container for containing mascara. The left half of the figure shows the state before the cap is completely attached, and the right half of the drawing shows the state after the cap is completely attached. Each state is shown.

図における１は内容物を収納する容器である。この容器１は内容物の収納空間を形成する容器本体１ａとこの容器本体１ａの開口部に液密状態で嵌合して容器の口部を形成するソケット１ｂとこのソケット１ｂの内側に嵌合保持されるしごき部材１ｃからなる。また、２は容器１の口部にねじ止めされるキャップ、３はキャップ２に固定保持された塗布具（ブラシ）である。   In the figure, 1 is a container for storing contents. The container 1 is fitted inside the socket 1b and a container body 1a that forms a storage space for the contents, a socket 1b that fits in an opening of the container body 1a in a liquid-tight state to form a mouth of the container It consists of the ironing member 1c hold | maintained. Reference numeral 2 denotes a cap screwed to the mouth of the container 1, and 3 denotes an applicator (brush) fixedly held on the cap 2.

キャップ２は内壁面にねじ部を有し容器１の口部の回りを取り囲む環状側壁２ａと、この環状側壁２ａの上端に一体成形される天面壁２ｂからなっており、環状側壁２ａの内側下端には容器１の口部の基端の拡大径部に設けられた凸部１ｂ１を乗り越えることによってその際の衝撃や打設音などによるクリック感を与えるとともにキャップ２の緩みを防止する突起ｃと、この突起ｃが凸部１ｂ１を乗り越えた後において容器の口部先端に当接して該口部を液密状態に保持するシール部材４とを備える。なお、本実施の形態では、環状側壁２の突起ｃが形成されている部位の厚さは、内壁面にねじ部が形成された環状側壁２ａの厚さと比較して薄肉になっており、これにより突起ｃが凸部１ｂ１を乗り越えるに際して突起ｃの形成部が弾性変形しやすくなり、スムーズな乗り越えが可能となる。 The cap 2 includes an annular side wall 2a having a threaded portion on the inner wall surface and surrounding the mouth of the container 1, and a top wall 2b integrally formed on the upper end of the annular side wall 2a. In this case, a protrusion c that gives a click feeling due to an impact or a driving sound at the time of getting over the convex portion 1b 1 provided at the enlarged diameter portion at the base end of the mouth portion of the container 1 and prevents the cap 2 from loosening. And a seal member 4 that abuts the tip of the mouth of the container after the projection c gets over the protrusion 1b 1 and holds the mouth in a liquid-tight state. In the present embodiment, the thickness of the portion of the annular side wall 2 where the protrusion c is formed is thinner than the thickness of the annular side wall 2a in which the thread portion is formed on the inner wall surface. Thus, when the projection c gets over the convex portion 1b 1 , the formation portion of the projection c is easily elastically deformed, and a smooth ride over becomes possible.

上記の構成になるキャップ２は突起ｃからシール部材４に至るまでの寸法Ｂ（図１の右側参照）が、容器１の口部先端から基端に設けられた凸部１ｂ１に至るまでの寸法Ａよりも大きくなっており、キャップ２の突起ｃが容器の凸部１ｂ１を乗り越えるまでとシール部材４が容器の口部先端に当接するまでの間に時間差があるので、クリック感が与えられ、キャップ２が抜け止めされたことが確実に把握することが可能であり、また、キャップ２の締め込みに際して突起ｃと凸部１ｂ１のみが短時間に接触するだけなので、摩耗によって緩み止め効果が劣化することもない。 The cap 2 configured as described above has a dimension B (see the right side of FIG. 1) from the protrusion c to the seal member 4 until the convex portion 1b 1 provided at the base end from the front end of the container 1 is reached. is larger than the dimension a, since the projection c of the cap 2 there is a time difference between the time to and the seal member 4 climbs the convexity 1b 1 of the container comes into contact with the mouth tip of the container, click feeling is given It is possible to reliably grasp that the cap 2 has been prevented from coming off, and since only the projection c and the convex portion 1b 1 come into contact in a short time when the cap 2 is tightened, the cap 2 is prevented from loosening due to wear. The effect does not deteriorate.

本発明に従うキャップ２は合成樹脂にて構成することができるもので、キャップ２の突起ｃ及び凸部１ｂ１の少なくとも何れか一方は抜け止め効果を確実に発揮させるために環状体とする。容器１側に形成される凸部１ｂ１を好ましくは環状体とし、キャップ２側の環状側壁２ａの下方薄肉部に形成される突起ｃを間欠的に設けると、突起ｃが凸部１ｂ１を乗り越える際に弾性変形しやすくなり突起ｃ及び凸部１ｂ１に対して過度の摩擦力が作用しない利点がある。なお、キャップ２が螺合される容器１は実施の形態で示したような合成樹脂製の容器に限るものではなく、ガラス容器や金属製の容器にも適用することができる。 The cap 2 according to the present invention can be composed of a synthetic resin, and at least one of the protrusion c and the convex portion 1b 1 of the cap 2 is an annular body in order to surely exert the retaining effect. The protrusion 1b 1 formed on the container 1 side is preferably an annular body, and when the protrusion c formed on the lower thin portion of the annular side wall 2a on the cap 2 side is intermittently provided, the protrusion c becomes the protrusion 1b 1 . There is an advantage that it is easy to be elastically deformed when getting over and excessive frictional force does not act on the protrusion c and the convex part 1b 1 . The container 1 into which the cap 2 is screwed is not limited to a synthetic resin container as shown in the embodiment, and can be applied to a glass container or a metal container.

構成部材の摩耗を生じることがなく、クリック感も明瞭なので使い勝手のよいキャップを提供できる。   The wear of the component members does not occur, and the click feeling is clear, so that a user-friendly cap can be provided.

本発明に従うキャップをマスカラ容器に提供した実施の形態を示した図である。It is the figure which showed embodiment which provided the cap according to this invention to the mascara container.
