Abstract

<P>PROBLEM TO BE SOLVED: To enable to check whether a screw cap is removed by a mischief or the like by a visual inspection while the attaching and detaching work of the screw cap is facilitated. <P>SOLUTION: A spiral part 21a to be engaged with a screw part 11 of a container main body 10 is provided on a cylindrical part 21 of the screw cap 20, and a wavy part 22a to be engaged with a sawtooth-like part 12a and rotatable only in the clockwise direction is provided on a base part 22 below this, and both are connected with each other through a perforation 20a. When the screw cap 20 is rotated in the counterclockwise direction by a hand, the cylindrical part 21 is guided by the screw part 11 and is moved upward, and on the other hand, as the base part 22 can not be rotated, the perforation 20a is broken, and the cylindrical part 21 is divided from the base part 22 and is separated from the container main body 10. Under this condition, as the base part 22 is also movable upward, it is removed from the container main body 10. In order to fit the screw cap 20 to the container main body 10, it is enough to rotate this in the clockwise direction. It is possible to check an existence of the mischief by visually viewing whether the screw cap 20 is divided or not. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、内容物収納容器に手動動作により着脱されるネジキャップ着脱機構およびそのためのネジキャップに関し、特に悪戯によりネジキャップが取り外されたかどうかを目視によりチェックできるネジキャップ着脱機構およびそのためのネジキャップに関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw cap attaching / detaching mechanism that is attached to and detached from a content storage container by manual operation, and a screw cap therefor, and in particular, a screw cap attaching / detaching mechanism that can check visually whether a screw cap has been removed due to mischief About.

なお、本発明は、
・貯留空間部の入口側の流入弁および出口側の吐き出し弁の作用により、容器本体の内容物をいったん当該貯留空間部に取り込んだ上でそれを外部空間に放出するポンプ式、
・利用者が容器本体の周面部分などを例えば押圧することにより内容物収納空間の容積が小さくなってその中の内容物が外部空間に放出される押出式、
の各製品に用いることができる。 In the present invention,
-A pump type that once takes the contents of the container body into the storage space part and then releases it to the external space by the action of the inlet valve on the inlet side and the outlet valve on the outlet side of the storage space part,
-An extrusion type in which the volume of the content storage space is reduced by the user pressing, for example, the peripheral surface portion of the container body, and the content therein is discharged to the external space,
It can be used for each product.

シャンプーなどの内容物を収納したポンプ式容器のネジキャップを外して異物を混入するなどのいたずらが多発し、これを防止するための悪戯防止機構が開示されている（例えば、特許文献１参照）。   A mischief prevention mechanism has been disclosed for preventing mischiefs such as removing screw caps of pump-type containers containing contents such as shampoo and mixing in foreign matters (see, for example, Patent Document 1). .

従来の悪戯防止機構では、ネジキャップを容器本体から手で簡単には取り外すことができないように両者を固く嵌合させている。   In the conventional mischief prevention mechanism, both screw caps are firmly fitted so that they cannot be easily removed from the container body by hand.

したがって、例えば内容物の詰め替えの際などにネジキャップを容器本体から取り外すには、ネジキャップの下縁部に冶具を挿入して強制的にテコ作用で上方向に持ち上げ、再び取り付けるには、ネジキャップ上縁部分に冶具を当てて強制的に容器本体に押し込む、といった操作が必要である。
特開平１１−１０５９５３号公報 Therefore, to remove the screw cap from the container body, for example, when refilling the contents, insert a jig into the lower edge of the screw cap, forcibly lift it upward, An operation is required in which a jig is applied to the upper edge of the cap and forcibly pushed into the container body.
Japanese Patent Laid-Open No. 11-105953

このように、従来の悪戯防止機構では、ネジキャップの取り外しには冶具が必要なので悪戯防止を図ることはできるものの、内容物の詰め替え作業自体が面倒であるといった問題点があった。   As described above, the conventional mischief prevention mechanism has a problem that although the jig cap is required for removing the screw cap, it is possible to prevent mischief, but the content refilling operation itself is troublesome.

そこで、本発明では、あくまでネジキャップの着脱作業の簡便化を図ることを第一とし、かつ、店頭に陳列された容器やホテルの客室などに用意されている容器などを見た者がその場の悪戯心で当該容器のネジキャップを取り外した場合、ネジキャップ自体が初期の「１ピース」状態から分割されてしまい、その後で分割ピースを再度容器に取り付けたとしても当該分割部分に対する目視などにより簡単かつ確実にこの悪戯をチェックできるようにすることを目的とする。   Therefore, in the present invention, the first is to simplify the screw cap attaching / detaching work, and a person who has seen a container displayed in a store or a container prepared in a hotel guest room, etc. When the screw cap of the container is removed due to the mischief of the above, the screw cap itself is divided from the initial “one piece” state, and even if the divided piece is attached to the container again after that, the visual inspection of the divided portion is performed. The purpose is to be able to check this mischief easily and reliably.

本発明は、この課題を次にようにして解決する。
（１）内容物収納容器（例えば後述の容器本体１０）の開口（例えば後述の開口部１０ａ）側周面のネジ部（例えば後述のネジ部１１）に、当該容器のネジキャップ（例えば後述のネジキャップ２０）を、手動操作のみによって取り外せる態様で結合させるネジキャップ着脱機構において、前記開口側周面の、前記ネジ部より下側部分に、前記ネジキャップがその取付方向へ回動することを許容し、かつ、いったん前記内容物収納容器に取り付けられた前記ネジキャップがその取外し方向へ回動することを阻止する、一方向性の係止部（例えば後述の鋸歯状部分１２ａ）を形成し、前記ネジキャップは、前記ネジ部に対応したネジ結合部（例えば後述の螺旋状部２１ａ）と、前記ネジ結合部より下側の、前記係止部に対応した一方向性の被係止部（例えば後述の波状部２２ａ）と、前記ネジキャップの取外し操作によって切断される、前記ネジ結合部および前記被係止部の境界部分（例えば後述のミシン目２０ａ）とを設ける。
（２）内容物収納容器（例えば後述の容器本体１０）の開口（例えば後述の開口部１０ａ）側周面のネジ部（例えば後述のネジ部１１）に、手動操作のみによって取り外せる態様で螺合するネジキャップ（例えば後述のネジキャップ２０）において、前記ネジ部に対応したネジ結合部（例えば後述の螺旋状部２１ａ）と、前記ネジ結合部より下側の一方向性の被係止部（例えば後述の波状部２２ａ）と、前記ネジキャップの取外し操作によって切断される、前記ネジ結合部および前記被係止部の境界部分（例えば後述のミシン目２０ａ）とを有し、前記一方向性の被係止部は、前記開口側周面の、前記ネジ部より下側部分に、前記ネジキャップがその取付方向へ回動することを許容し、かつ、いったん前記内容物収納容器に取り付けられた前記ネジキャップがその取外し方向へ回動することを阻止する態様で形成された、一方向性の係止部（例えば後述の鋸歯状部分１２ａ）に対応する。 The present invention solves this problem as follows.
(1) A screw cap (for example, described later) is attached to a screw portion (for example, threaded portion 11 to be described later) on the peripheral surface of an opening (for example, to an opening 10a to be described later) of a content storage container (for example, a container body 10 to be described later). In the screw cap attaching / detaching mechanism in which the screw cap 20) is coupled in such a manner that it can be removed only by a manual operation, the screw cap is rotated in the mounting direction on the lower side portion of the screw portion on the peripheral surface of the opening. A unidirectional locking portion (for example, a sawtooth portion 12a to be described later) is formed which permits and prevents the screw cap once attached to the content container from rotating in the removing direction. The screw cap includes a screw coupling portion (for example, a spiral portion 21a to be described later) corresponding to the screw portion, and a unidirectional engagement corresponding to the locking portion below the screw coupling portion. Parts (for example, below the corrugated portion 22a), the cleaved by removal operation of the screw cap, the screw connection and the provision of the boundary portion of the engagement portion (e.g., below the perforations 20a).
(2) Screwed into a screw portion (for example, a screw portion 11 described later) on the side surface of an opening (for example, an opening portion 10a described later) of a contents storage container (for example, a container body 10 described later) in a manner that can be removed only by manual operation. In a screw cap (for example, a screw cap 20 described later), a screw coupling portion (for example, a spiral portion 21a described later) corresponding to the screw portion, and a unidirectional locked portion (below the screw coupling portion) ( For example, it has a wavy portion 22a), which will be described later, and a boundary portion (for example, a perforation 20a, which will be described later) between the screw coupling portion and the locked portion, which is cut by an operation of removing the screw cap. The locked portion allows the screw cap to turn in the mounting direction at a lower portion of the opening-side peripheral surface than the screw portion, and is once attached to the content storage container. Before Screw cap is formed in a manner that prevents the pivoting to its removal direction corresponds to the direction of the locking portion (e.g., serrations 12a which will be described later).

本発明では、このように、ネジキャップを手動操作で取り外せるので、内容物の詰め替え作業を簡単に行うことができる。   In the present invention, since the screw cap can be removed manually as described above, the contents can be refilled easily.

また、ネジキャップの取り外し方向への回動操作により、当該ネジキャップは分割されるので、これを目視することによりネジキャップが、例えば悪戯により取り外されたかどうかをチェックすることができる。   Further, since the screw cap is divided by the rotation operation in the removal direction of the screw cap, it is possible to check whether the screw cap has been removed by mischief, for example, by visually observing this.

をそれぞれ示している。 In these figures,
1 is a pump container that is used repeatedly by refilling the contents,
Reference numeral 10 denotes a container main body, 10a accommodates an operation member 30 to be described later and an opening for refilling contents, and 11 denotes a cylindrical portion 21 of a screw cap 20 to be described later which is formed on the outer peripheral surface of the opening. A screw portion for rotating counterclockwise, 12 is a shoulder portion having a diameter larger than that of the screw portion, and 12a is formed around the shoulder portion in a clockwise direction so that a base portion 22 of a screw cap 20 to be described later is formed. A sawtooth portion for rotating only in the clockwise direction, 12b is a convex curved surface portion formed so as to spread outward in the clockwise direction of the sawtooth portion, 12c is a step portion following the convex curved surface portion,
20 is a screw cap for opening / closing the opening 10a of the container body 10, and 20a is broken by turning the screw cap 20 counterclockwise when the opening 10a of the container body 10 is opened. 21 is a cylindrical portion that is separated by breakage of the perforation; 21a is a spiral portion that is formed on the inner peripheral surface of the cylindrical portion and engages with the screw portion 11 of the container body 10; Is a base formed with a diameter larger than that of the cylindrical portion 21, 22a is a wavy portion corresponding to the sawtooth portion 12a, 22b is a concave curved surface portion corresponding to the convex curved portion 12b of the sawtooth portion 12a, 22c is an upright portion having a shape corresponding to the step portion 12c of the serrated portion 12a,
Reference numeral 30 denotes an operation member for discharging the contents to the external space.

ここで、時計方向，反時計方向とは、容器本体１０の開口部１０ａを上から見たときの回動方向、またはネジキャップ２０の基部２２を下にして筒状部２１を上から見たときの回動方向である。   Here, the clockwise direction and the counterclockwise direction are the rotation direction when the opening 10a of the container body 10 is viewed from above, or the cylindrical portion 21 when viewed from above with the base 22 of the screw cap 20 facing down. Is the direction of rotation.

ポンプ容器１は、ネジキャップ２０の着脱を手動操作でできるようにしたまま、例えば、容器本体１０に異物を混入するなどの悪戯が行われたかどうかを視認できるようにしたものである。   The pump container 1 is configured so that, for example, it can be visually confirmed whether or not a mischief such as mixing a foreign substance into the container body 10 is performed while the screw cap 20 can be attached and detached manually.

図１（ａ）および（ｂ）に示すように、ネジキャップ２０の筒状部２１と基部２２とはミシン目２０ａで接続され、当該ネジキャップと容器本体１０とは、
・筒状部２１の螺旋状部分２１ａがネジ部１１と係合し、
・基部２２の波状部分２２ａの凹状曲面部２２ｂおよび起立部２２ｃが、それぞれ肩部１２の鋸歯状部分１２ａの凸状曲面部１２ｂおよび段部１２ｃに係合する、
態様となっている。 As shown in FIGS. 1A and 1B, the cylindrical portion 21 and the base portion 22 of the screw cap 20 are connected by a perforation 20a, and the screw cap and the container body 10 are
-The spiral portion 21a of the cylindrical portion 21 is engaged with the screw portion 11,
The concave curved surface portion 22b and the upright portion 22c of the waved portion 22a of the base portion 22 engage with the convex curved surface portion 12b and the stepped portion 12c of the sawtooth portion 12a of the shoulder portion 12, respectively.
It is an aspect.

ここで、ネジキャップの２０の筒状部２１と基部２２とは手で分離できるように接続されていればよく、ミシン目２０ａに代えて、例えば筒状部２１と基部２２との境界部分を薄肉に形成してもよい。   Here, the cylindrical portion 21 and the base portion 22 of the screw cap 20 need only be connected so as to be separable by hand. For example, instead of the perforation 20a, a boundary portion between the cylindrical portion 21 and the base portion 22 is provided. You may form thinly.

そして、このような構成により、
・ネジキャップ２０の筒状部２１は、容器本体１０に対して時計方向，反時計方向に回動して上下動可能であり、
・ネジキャップ２０の基部２２は、容器本体１０に対して時計方向に回動可能だが、反時計方向には回動できず、
・筒状部２１と基部２２とはミシン目２０ａによって分離され易くなっている。 And with such a configuration,
The cylindrical portion 21 of the screw cap 20 can be moved up and down by rotating clockwise and counterclockwise with respect to the container body 10.
The base 22 of the screw cap 20 can be rotated clockwise with respect to the container body 10, but cannot be rotated counterclockwise.
-The cylindrical part 21 and the base part 22 are easily separated by the perforation 20a.

なお、ネジキャップ２０の基部２２は、ミシン目２０ａの破断により筒状部２１が取り外された状態では、もはやネジ結合部分がなくなって容器本体１０との間で単に反時計方向に回らないだけであり、容器本体１０に対しては上動可能である。   It should be noted that the base 22 of the screw cap 20 does not simply turn counterclockwise between the container body 10 and the screw coupling portion when the cylindrical portion 21 is removed due to the break of the perforation 20a. Yes, the container body 10 can be moved upward.

図１（ａ）に示すように、ネジキャップ２０の筒状部２１を手で持って反時計方向に回動させると、
・螺旋状部２１ａが容器本体１０のネジ部１１に案内されるかたちで反時計方向に回動し、
・基部２２の起立部２２ｃは肩部１２の段部１２ｃに係合し、容器本体１０に対して反時計方向に回動できない。 As shown in FIG. 1A, when the cylindrical portion 21 of the screw cap 20 is held by hand and rotated counterclockwise,
-The spiral portion 21a rotates counterclockwise in the form guided by the screw portion 11 of the container body 10,
The upright portion 22 c of the base portion 22 engages with the step portion 12 c of the shoulder portion 12 and cannot rotate counterclockwise with respect to the container body 10.

その結果、図２（ａ）に示すように、
・ミシン目２０ａが破断されて筒状部２１は分離され、
・筒状部２１はその螺旋状部２１ａがネジ部１１に案内されて上動していき、容器本体１０から外れる。 As a result, as shown in FIG.
The perforation 20a is broken and the cylindrical portion 21 is separated,
The cylindrical portion 21 moves upward as the spiral portion 21 a is guided by the screw portion 11 and is detached from the container body 10.

したがって、操作部材３０を容器本体１０から取り外すことができ、開口部１０ａから内容物の詰め替えを行うことができる。   Therefore, the operation member 30 can be removed from the container main body 10, and the contents can be refilled from the opening 10a.

この状態ではネジキャップ２０の基部２２は容器本体１０に残ったままであるが、前述のように、基部２２をそのまま上方向に移動させると容器本体１０から取り外すことができる（図２(ｂ)参照）。   In this state, the base 22 of the screw cap 20 remains in the container main body 10, but as described above, it can be removed from the container main body 10 by moving the base 22 upward as it is (see FIG. 2B). ).

なお、内容物の詰め替えは、ネジキャップ２０の筒状部２１のみを取り外した状態で行ってもよいし、基部２２も取り外した状態で行ってもよい。   The refilling of the contents may be performed with only the cylindrical portion 21 of the screw cap 20 removed, or may be performed with the base portion 22 also removed.

内容物を詰め替え後、ネジキャップ２０を容器本体１０に取り付けるには、容器本体１０の開口部１０ａにネジキャップ２０を被せ、当該ネジキャップを手で時計方向に回動させるだけでよい。   In order to attach the screw cap 20 to the container main body 10 after refilling the contents, it is only necessary to put the screw cap 20 on the opening 10a of the container main body 10 and rotate the screw cap clockwise by hand.

このとき、ネジキャップ２０は、
・その基部２２が容器本体１０のネジ部１１から離れた外側部分を空回りしながら筒状部２１の螺旋状部２１ａがネジ部１１に螺合して下動し、
・やがて基部２２が肩部１２の位置迄下がってくると、当該基部の内周面に形成された波状部２２ａの起立部２２ｃが当該肩部の鋸歯状部分１２ａの凸状曲面部１２ｂに案内されることとなり、
・最終的には基部２２の起立部２２ｃが肩部１２の段部１２ｃに係合するかたちで、
容器本体１０に取り付けられる。 At this time, the screw cap 20 is
-The spiral portion 21a of the cylindrical portion 21 is screwed into the screw portion 11 while the base portion 22 idles the outer portion away from the screw portion 11 of the container body 10, and moves downward.
When the base portion 22 is lowered to the position of the shoulder portion 12, the upright portion 22c of the wavy portion 22a formed on the inner peripheral surface of the base portion is guided to the convex curved surface portion 12b of the sawtooth portion 12a of the shoulder portion. Will be
-Ultimately, the upright portion 22c of the base portion 22 is engaged with the step portion 12c of the shoulder portion 12,
It is attached to the container body 10.

ネジキャップ２０の基部２２がネジ部１１に引っ掛かることなくスムーズに肩部１２と係合できるのは、基部２２が（ネジ部１１と係合する）筒状部２１よりも大径だからである。   The base portion 22 of the screw cap 20 can be smoothly engaged with the shoulder portion 12 without being caught by the screw portion 11 because the base portion 22 has a larger diameter than the cylindrical portion 21 (which engages with the screw portion 11).

なお、ポンプ容器１に異物を混入するなどの悪戯をする際にもネジキャップの取り外しにともない、前述の内容物詰め替え作業と同様に、ミシン目２０ａが破断されてネジキャップ２０は筒状部２１と基部２２とに分離される。   In addition, when a mischief such as mixing foreign matter into the pump container 1 is performed, the perforation 20a is broken and the screw cap 20 is formed in the cylindrical portion 21 in the same manner as the above-described content refilling operation with the removal of the screw cap. And the base 22.

したがって、悪戯後にネジキャップ２０が再び容器本体１０に取り付けてあったとしても、当該ネジキャップはすでに分離された状態なのでこれを目視することによりポンプ容器１が悪戯により開封されたことを確認できる。   Therefore, even if the screw cap 20 is attached to the container body 10 again after the mischief, since the screw cap has already been separated, it can be confirmed that the pump container 1 has been opened by mischief by viewing it.

なお、ミシン目２０ａの破断の有無を確認してから使用する旨を容器本体１０などに記入して利用者に通知してもよい。   Note that the user may be notified of the fact that the perforation 20a is to be used after confirming whether or not the perforation 20a has been broken.

容器本体に収納する内容物としては、金属塩類粉末、無機物粉末や樹脂粉末などを用いる。例えば、タルク，カオリン，アルミニウムヒドロキシクロライド（アルミ塩），硫酸バリウム，セルロース，これらの混合物などである。また、紫外線吸収剤，油性原料，界面活性剤，保湿剤，高分子化合物，酸化防止剤、金属イオン封鎖剤なども用いる。
As the contents stored in the container body, metal salt powder, inorganic powder, resin powder, or the like is used. For example, talc, kaolin, aluminum hydroxychloride (aluminum salt), barium sulfate, cellulose, and a mixture thereof. In addition, ultraviolet absorbers, oily raw materials, surfactants, humectants, polymer compounds, antioxidants, sequestering agents, and the like are also used.
