Description

本発明は、飲みきりタイプの飲料ボトルや詰め替え容器等に多く用いられている簡易型の容器用キャップに関するものであり、とくには、容器の注出開口を閉塞する天板を、下向きに開放された環状溝を形成する内外二重の筒体に一体連結して、その環状溝を打栓によって容器の口頚部先端に嵌合させて固定保持するベースと、このベースを取り囲んで、筒体の口頚部先端に対する嵌合力を強化する環状帯とを備えたものである。   The present invention relates to a simple container cap that is often used for drink-type beverage bottles, refill containers, and the like, and in particular, the top plate that closes the dispensing opening of the container is opened downward. A base that is integrally connected to the inner and outer double cylinders that form the annular groove, and that the annular groove is fitted and fixed to the tip of the mouth neck of the container by a stopper, and surrounding the base, It is provided with an annular band that reinforces the fitting force with respect to the tip of the mouth and neck.

この種の容器用キャップは、ドリンク剤等で使用される飲みきりタイプの飲料容器や、詰め替え容器等に多用されており、たとえば、特許文献１に開示されたものが知られている。   This type of container cap is widely used for drink-type beverage containers used in drinks, refill containers, and the like. For example, the one disclosed in Patent Document 1 is known.

これは、ビン口内壁に嵌合する胴部を円盤部で被冠するとともに、その円盤部と、それの外側に同心円状に位置する環状把手部とを一部破断可能に、一部一体的に連結し、環状把手部を引き上げることによって、胴部をビン口から抜き出して開栓するものである。   This is because the body part that fits into the inner wall of the bin mouth is crowned by the disk part, and the disk part and the annular handle part that is concentrically located outside of the disk part can be partly broken, partly integrated The body portion is pulled out from the bottle opening and opened by pulling up the annular handle portion.

特許第４１５２７１７号公報Japanese Patent No. 4152717

しかるにこの従来の容器用キャップは、胴部がビン口内壁に単に嵌合しているにすぎず、破断可能連結部を破断せずとも容器の注出開口から引き抜くことできるおそれがあり、不正な開封が行われたかどうかを確実に判断できるとはいえないところに問題を残している。   However, in this conventional container cap, the body part is merely fitted to the inner wall of the bottle mouth, and there is a possibility that the breakable connecting part can be pulled out from the dispensing opening of the container. The problem remains in that it cannot be surely determined whether or not opening has been performed.

本発明の課題は、容器の注出開口に対する嵌合力を高めて容器の確実な密封が行える一方、開封時には容易に開封を行うことが可能であり、しかも容器を正規に開封する前に不正な開封が行われたか否かを目視で確実に判断できる容器用キャップを提案することにある。   The object of the present invention is to increase the fitting force with respect to the dispensing opening of the container and perform reliable sealing of the container, but it is possible to easily open the container at the time of opening, and it is illegal to open the container properly. An object of the present invention is to propose a container cap that can reliably determine whether or not opening has been performed.

本発明の容器用キャップは、容器の注出開口を閉塞する天板を、下向きに開放された環状溝を形成する内外二重の筒体に一体連結して、該環状溝を容器の口頚部先端に嵌合させて固定保持するベースと、このベースを取り囲んで該筒体の該口頚部先端に対する嵌合力を強化する環状帯とを備えた容器用キャップであって、
前記ベースと前記環状帯との相互間に、該ベースおよび該環状帯をその天面上端部の少なくとも一部分において分離可能に連結する天面弱化片と、該天面弱化片よりも下方の位置で該ベースおよび該環状帯を分離不能に連結するとともに該環状帯の引き起こしにより該天面弱化片を破断して該ベースを容器の口頚部先端より離脱させる連結片を設けたことを特徴とする容器用キャップである。 The container cap according to the present invention integrally connects a top plate that closes the dispensing opening of the container to an inner and outer double cylindrical body that forms an annular groove opened downward, and the annular groove is connected to the mouth and neck of the container. A container cap comprising a base that is fitted and fixed to the tip, and an annular band that surrounds the base and reinforces the fitting force to the tip of the mouth and neck of the cylinder,
Between the base and the annular band, a top surface weakening piece that detachably connects the base and the annular band at at least a part of the upper end portion of the top surface, and a position below the top surface weakening piece A container characterized in that the base and the annular band are connected inseparably and a connecting piece for breaking the top surface weakening piece by causing the annular band to disengage the base from the tip of the neck of the container is provided. It is a cap.

２）天面弱化片が設けられた領域を除く下方領域において該ベースおよび該環状帯を分離可能に連結する少なくとも１つの弱化ブリッジを設けること。
３）ベースの外周壁および前記環状帯の内周壁の少なくとも一方に、前記弱化ブリッジに隣接する保護突起を設けること。さらに、
４）ベースの外周壁および前記環状帯の内周壁の少なくとも一方に、前記天面弱化片に隣接する保護突起を設けること。 In the present invention, it is preferable to add the following components to the container cap having the above-described configuration. That is,
1) The top surface weakening piece is provided at a lateral position on the front side of the annular band that is the starting point of the annular band.
2) Providing at least one weakening bridge that detachably connects the base and the annular band in a lower region excluding a region where the top surface weakening piece is provided.
3) Provide a protective projection adjacent to the weakening bridge on at least one of the outer peripheral wall of the base and the inner peripheral wall of the annular band. further,
4) Providing a protective projection adjacent to the top surface weakening piece on at least one of the outer peripheral wall of the base and the inner peripheral wall of the annular band.

ここで、「天面弱化片に隣接する」、「弱化ブリッジに隣接する」とは、文字通り隣接する場合の他、天面弱化片、弱化ブリッジから離隔して位置する場合、あるいは天面弱化片、弱化ブリッジの縁部に一体的に連結している場合をも含むものとする。   Here, “adjacent to the top surface weakening piece” and “adjacent to the weakening bridge” are literally adjacent to each other, as well as being located away from the top surface weakening piece, the weakening bridge, or the top surface weakening piece. In addition, the case where it is integrally connected to the edge of the weakening bridge is also included.

また、「保護突起」は、突起状のもの、あるいはリブ状のものを適用することができ、天面弱化片、弱化ブリッジの破断痕が残る部分（ベース、環状帯のいずれか一方）に隣接する場合のみならず、その上方および下方の少なくとも一方に設けることもできる。   In addition, “protective protrusions” can be protrusion-shaped or rib-shaped, and are adjacent to the top surface weakening piece or the portion (one of the base or annular belt) where the weakening bridge remains. It can be provided not only in the case of, but also in at least one of the upper and lower sides.

また、天面弱化片、弱化ブリッジには、その破断を容易にするため、薄肉部、ミシン目状の穿孔あるいはスリット状の切れ込み等の分断予定端を設けておくことが好ましい。保護突起については、ベースを構成する外側の筒体の外周壁に設けておくのが好ましい。   Moreover, in order to make the top surface weakening piece and the weakening bridge easy to break, it is preferable to provide a scheduled end portion such as a thin-walled portion, a perforated hole or a slit-like cut. About a protection protrusion, it is preferable to provide in the outer peripheral wall of the outer cylinder which comprises a base.

上記構成からなる本発明の容器用キャップによれば、ベースの周りに環状帯を設け、該環状帯をベースの箍として機能させるようにしたため容器用キャップの、容器の口頚部に対する嵌合がより強固になる。   According to the container cap of the present invention having the above structure, an annular band is provided around the base, and the annular band is made to function as a ridge of the base, so that the container cap can be more fitted to the mouth-neck portion of the container. Become strong.

また、本発明の容器用キャップによれば、環状帯の引き起こすことにより、容器用キャップの、容器の口頚部における嵌合力を弱めることが可能となり、連結部を介してベースキャップを引き上げるだけで容器を簡単に開封することができる。   Further, according to the container cap of the present invention, it is possible to weaken the fitting force of the container cap at the mouth-neck portion of the container by causing the annular band, and the container can be simply pulled up through the connecting portion. Can be opened easily.

また、本発明の容器用キャップによれば、環状帯を引き起こす際に、天面弱化片が破断するため、容器の正規の開封前に不正な開封が行われたかどうかを、容器用キャップの天面側を視認するだけで簡単に見分けることができる。   Further, according to the container cap of the present invention, when the annular band is caused, the top surface weakening piece is broken, so whether or not the container cap is unfairly opened before the container is properly opened is determined. It can be easily identified by simply viewing the surface side.

また、本発明の容器用キャップによれば、天面弱化片を、環状帯の引き起こし起点となる該環状帯の前面側の側方位置に設けたことにより、環状帯を引き起こす向きと天面弱化片が破断する向きがほぼ一致することになり、該天面弱化片をより小さな力でスムーズに破断することができる。   Further, according to the container cap of the present invention, the top surface weakening piece is provided at a lateral position on the front side of the annular band that causes the annular band, and the direction and the top surface weakening are caused. The direction in which the pieces break is almost the same, and the top weakened piece can be smoothly broken with a smaller force.

また、本発明の容器用キャップによれば、天面弱化片が設けられた領域を除く下方領域に、該ベースおよび該環状帯を分離可能に連結する少なくとも１つの弱化片を設けたため、環状帯の、ベースに対する取り付け姿勢を安定的に保持することができる。   According to the container cap of the present invention, since the at least one weakening piece for detachably connecting the base and the annular band is provided in the lower region excluding the region where the top surface weakening piece is provided, the annular band is provided. The mounting posture with respect to the base can be stably maintained.

また、本発明の容器用キャップによれば、ベースの外周壁および環状帯の内周壁の少なくとも一方に、弱化ブリッジに隣接する保護突起を設けたため、容器の開封時に該弱化ブリッジの破断箇所に、先端が尖った、内向きまたは外向きの破断痕が発生しても、保護突起の作用下で、開封作業を行う需要者の手指への破断痕の接触の程度を小さくすることが可能となり、それによる不快な刺激が軽減される。   Further, according to the container cap of the present invention, since the protective projection adjacent to the weakening bridge is provided on at least one of the outer peripheral wall of the base and the inner peripheral wall of the annular band, at the breakage point of the weakening bridge when the container is opened, Even if an inward or outward rupture mark with a sharp tip is generated, it becomes possible to reduce the degree of contact of the rupture mark to the finger of the consumer who performs the opening operation under the action of the protective protrusion, The unpleasant irritation caused thereby is reduced.

とくに、天面弱化片に隣接する部位に保護突起を設ける場合にあっては、該天面弱化片の破断箇所に、先端が尖った、内向きまたは外向きの破断痕が発生しても、保護突起の作用下で、開封作業を行う需要者の手指への破断痕の接触の程度を小さくすることが可能となり、それによる不快な刺激が軽減される。   In particular, in the case where a protective projection is provided at a site adjacent to the top surface weakening piece, even if an inward or outward breaking mark occurs at the tip of the top surface weakening piece, the tip is sharp, Under the action of the protective protrusion, it is possible to reduce the degree of contact of the fracture mark with the finger of the consumer who performs the opening operation, thereby reducing unpleasant irritation.

FIG. 4 is a view showing a cross section taken along the line BB of FIG. 1, and FIG. 4 is a view showing a state in which an annular band is caused in the container cap shown in FIG.

図１〜４において、符号１は、容器用キャップである。この容器用キャップ１は、容器の口頚部先端２の注出開口２ａを閉塞する天板１ａと、上端同士を一体連結して下向きに開放された環状溝１ｂを形成するとともにその内側下端を連結部１ｈに連結した内外の筒体１ｃ、１ｄ（以下、内側の筒体を内筒１ｃで表示し、外側の筒体を外筒１ｄで表示する）とによって構成されたベース１ｅを備えている。   1-4, the code | symbol 1 is a cap for containers. The container cap 1 forms a top plate 1a that closes the pouring opening 2a of the mouth-neck end 2 of the container, and an annular groove 1b that is open at the top by connecting the top ends together, and connects the bottom end at the inside. And a base 1e configured by inner and outer cylinders 1c and 1d connected to the portion 1h (hereinafter, the inner cylinder is indicated by the inner cylinder 1c and the outer cylinder is indicated by the outer cylinder 1d). .

このベース１ｅは、内筒１ｃと外筒１ｄとの間の環状溝１ｂを打栓によって容器の口頚部先端２に嵌合させて該ベース１ｅを固定保持するものであって、このベース１ｅの外側には、該ベース１ｅを取り囲んで内筒１ｃ、外筒１ｄの口頚部先端２に対する嵌合力を強化する環状帯３が設けられている。なお、環状帯３はその前面側の外壁（その中心軸線に対し連結片の形成位置とは、直径方向に対向する外周面）に、半径方向外方へ突出する、たとえばリップ状の平面形状の指掛け片３ａを設けられる。   This base 1e is configured to fix and hold the base 1e by fitting an annular groove 1b between the inner cylinder 1c and the outer cylinder 1d to the mouth neck portion 2 of the container with a stopper. On the outside, there is provided an annular band 3 that surrounds the base 1e and reinforces the fitting force of the inner cylinder 1c and the outer cylinder 1d with respect to the distal end 2 of the mouth neck. The annular band 3 protrudes radially outward on an outer wall on the front surface side (the formation position of the connecting piece with respect to the central axis is an outer peripheral surface facing the diameter direction), for example, a lip-shaped planar shape. A finger-hanging piece 3a is provided.

なお、図１（ａ）（ｂ）に示すところでは、外筒１ｄの一条の内周突状１ｆと口頚部先端２の一条の外周突状２ｂとのアンダーカット嵌合によって、口頚部先端２を内筒１ｃと外筒１ｄとの間で挟持する嵌合固定状態を実現している。   1 (a) and 1 (b), the mouth and neck tip 2 is formed by undercut fitting between the inner protrusion 1f of the outer tube 1d and the outer protrusion 2b of the mouth and neck tip 2. Is fitted and fixed between the inner cylinder 1c and the outer cylinder 1d.

また、符号４は、ベース１ｅの外筒１ｄと環状帯３との相互間に設けられた天面弱化片である。この天面弱化片４は、ベース１ｅの外筒１ｄおよび環状帯３を、その天面上端部の少なくとも一部分において分離可能に連結する薄肉板状部材から構成されている。指掛け片３ａを把持して帯状体３を引き起こしベース１ｅの外筒１ｄと環状帯３を分離するとき、該天面弱化片４は前側端縁４ａから破断が始まり後側端縁４ｂにおいて破断を完了するものであって、この前側端縁４ａと後側端縁４ｂとの相互間に破断予定端（線）４ｃが形成される。   Reference numeral 4 denotes a top weakening piece provided between the outer cylinder 1d of the base 1e and the annular band 3. The top surface weakening piece 4 is formed of a thin plate-like member that detachably connects the outer cylinder 1d and the annular band 3 of the base 1e at at least a part of the upper end portion of the top surface. When gripping the finger-hanging piece 3a to cause the strip 3 to separate the outer cylinder 1d of the base 1e and the annular band 3, the top surface weakening piece 4 starts to break from the front edge 4a and breaks at the rear edge 4b. Completion | finish, Comprising: The fracture | rupture planned end (line | wire) 4c is formed between this front side edge 4a and the rear side edge 4b.

ここでは、天面上端部の少なくとも一部分として、天面弱化片４を、環状帯３の引き起こし起点となる該環状帯３の前面側（指掛け片３ａが設けられている側）の側方位置に二つ設け、前側端縁４ａ、後側端縁４ｂおよびこれらを結ぶ破断予定端４ｃをベース１ｅの外筒１ｄの外周壁に一致させることにより該天面弱化片４を該外筒１ｄの外周壁に沿わせて破断させるものを例として示したが、前側端縁４ａ、後側端縁４ｂおよび破断予定端４ｃを環状帯３の内周壁に一致させて天面弱化片４を破断することも可能であり、この点については限定されない。   Here, as at least a part of the upper end of the top surface, the top surface weakening piece 4 is placed at a lateral position on the front side of the annular band 3 that is the starting point of the annular band 3 (the side on which the finger hanging piece 3a is provided). Two of the front side edge 4a, the rear side edge 4b, and the expected breaking end 4c connecting these are made to coincide with the outer peripheral wall of the outer cylinder 1d of the base 1e, whereby the top surface weakening piece 4 is attached to the outer periphery of the outer cylinder 1d. Although an example in which the material is broken along the wall is shown as an example, the top surface weakening piece 4 is broken by making the front side edge 4a, the rear side edge 4b, and the planned breaking edge 4c coincide with the inner peripheral wall of the annular band 3. However, this point is not limited.

前側端縁４ａ、後側端縁４ｂおよび破断予定端４ｃをベース１ｅの外周壁に一致させて天面弱化片４を破断する場合、その破断痕は、環状帯３の内周壁に残ることになり、逆に、前側端縁４ａ、後側端縁４ｂおよび破断予定端４ｃを環状帯３の内周壁に一致させて天面弱化片４を破断する場合には、その破断痕は、ベース１ｅの外筒１ｄの外周壁に残ることになる。なお、天面弱化片４の破断を容易ならしめるため、破断予定端４ｃは、薄肉部、ミシン目状の穿孔あるいはスリット状の切れ込み等によって形成するのが好ましい。   When the front side edge 4a, the rear side edge 4b, and the planned fracture end 4c are made to coincide with the outer peripheral wall of the base 1e and the top surface weakening piece 4 is broken, the fracture mark remains on the inner circumferential wall of the annular band 3. On the contrary, when the top surface weakening piece 4 is broken by making the front side edge 4a, the rear side edge 4b, and the planned breaking edge 4c coincide with the inner peripheral wall of the annular band 3, the breaking mark is the base 1e. Will remain on the outer peripheral wall of the outer cylinder 1d. In order to facilitate breakage of the top surface weakening piece 4, it is preferable that the planned break end 4 c be formed by a thin portion, perforated perforations, slit-like cuts, or the like.

天面弱化片４の平面形状は所要に応じて適宜変更することができるものであって図示のものに限定されることはない。   The planar shape of the top surface weakening piece 4 can be appropriately changed as necessary, and is not limited to the illustrated one.

また、５は、ベース１ｅの外筒１ｄおよび環状帯３を分離不能に連結する連結片である。この連結片５は、ベース１ｅの背面側（指掛け片３ａが設けられた対向位置）で、天面弱化片４よりも下方の部位に設けられており、環状帯３を引き起こして容器を開封する際に、ベース１ｅはこの連結片５を介して容器の口頚部先端２から離脱する。   Reference numeral 5 denotes a connecting piece that connects the outer cylinder 1d of the base 1e and the annular band 3 in an inseparable manner. The connecting piece 5 is provided at a position below the top surface weakening piece 4 on the back side of the base 1e (opposite position where the finger hanging piece 3a is provided), and causes the annular band 3 to open the container. At this time, the base 1e is detached from the mouth / neck tip 2 of the container through the connecting piece 5.

連結片５は、天面弱化片４よりも下方に設けられていればよいが、とりわけ、ベース１ｅの外筒１ｄの下端および環状帯３の下端に設けるのが好ましく、これにより、環状帯３を引き起こす際に、外筒１ｄに設けられた内周突状１ｆが径方向の外側へ向けて引っ張られるため、口頚部先端２に設けられた外周突条２ｂとの嵌合が解除しやすくなり、より小さい力で容器の開封が可能となる。   The connecting piece 5 only needs to be provided below the top surface weakening piece 4, but in particular, it is preferably provided at the lower end of the outer cylinder 1 d of the base 1 e and the lower end of the annular band 3. When this occurs, the inner peripheral projection 1f provided on the outer cylinder 1d is pulled outward in the radial direction, so that the fitting with the outer peripheral protrusion 2b provided on the distal end 2 of the neck and neck is easy to be released. The container can be opened with a smaller force.

また、符号６は、天面弱化片４が設けられた領域を除く下方領域、とくに、ベース１ｅと環状帯３との下端に設けられた弱化ブリッジである。この弱化ブリッジ６は、ベース１ｅおよび環状帯３を分離可能に連結するものであって、この弱化ブリッジ６によって環状帯３の、ベース１ｅに対する取り付け姿勢の安定化が図られている。この弱化ブリッジ６は、環状帯３の引き起こしに際して破断する。   Reference numeral 6 denotes a weakening bridge provided in a lower region excluding the region where the top surface weakening piece 4 is provided, in particular, at the lower ends of the base 1 e and the annular band 3. The weakening bridge 6 connects the base 1e and the annular band 3 so as to be separable, and the weakening bridge 6 stabilizes the mounting posture of the annular band 3 with respect to the base 1e. This weakening bridge 6 breaks when the annular band 3 is raised.

弱化ブリッジ６は、少なくとも１つ設けられるものである。弱化ブリッジン６を複数設ける場合には、ベース１ｅの周りに沿って間隔をおいて配置するのがよい。   At least one weakening bridge 6 is provided. In the case where a plurality of weakened bridges 6 are provided, it is preferable to arrange them at intervals along the periphery of the base 1e.

弱化ブリッジ６の平面形状は、環状帯３に向けて先細りとなる台形形状としたものを例示したが、弱化ブリッジ６の配設個所や平面形状等は、適宜変更することができる。   The planar shape of the weakening bridge 6 is exemplified as a trapezoidal shape that tapers toward the annular band 3, but the location of the weakening bridge 6, the planar shape, and the like can be changed as appropriate.

弱化ブリッジ６の平面形状を、環状帯３に向けて先細りとなる台形形状とし、かつ、その断面形状を、環状帯３に向けて漸次に薄肉化したものを適用する場合には、該弱化ブリッジ６の分断予定端６ａは、環状帯３との連結部位（環状帯３と弱化ブリッジ６の境界）に位置し、抜栓時に弱化ブリッジ４の破断痕は、外筒１ｄ側に残ることになる。とくに弱化ブリッジ４の破断痕が外筒１ｄ側に残る場合においては、環状帯３そのものに指を掛けて引き起こす際に、弱化ブリッジ４の破断痕による手指への不快な刺激を無くすことができる利点がある。   When the planar shape of the weakened bridge 6 is a trapezoidal shape that tapers toward the annular band 3 and the cross-sectional shape is gradually thinned toward the annular band 3, the weakened bridge 6 is applied. 6 is located at a connection portion with the annular band 3 (a boundary between the annular band 3 and the weakening bridge 6), and the breakage mark of the weakening bridge 4 remains on the outer cylinder 1d side when unplugged. In particular, when the fracture mark of the weakened bridge 4 remains on the outer cylinder 1d side, when the finger is put on the annular band 3 itself, an unpleasant stimulus to the finger due to the fracture mark of the weakened bridge 4 can be eliminated. There is.

なお、弱化ブリッジ６の分断予定端６ａは、外筒１ｄとの連結部位としてもよく、その場合には、先端が尖った弱化ブリッジ６の破断痕は環状帯３の内周壁に残ることになる。   In addition, the division | segmentation planned end 6a of the weakening bridge 6 is good also as a connection part with the outer cylinder 1d, In that case, the fracture | rupture trace of the weakening bridge 6 with the pointed tip will remain on the inner peripheral wall of the annular band 3. .

分断予定端６ａは、弱化ブリッジ６の幅寸法や厚さを適宜変更してその平面形状を変化させることによって容易に形成することができる（幅寸法の変更等）が、薄肉部を設けたり、ミシン目状の穿孔、あるいはスリット状の切れ込みを設けることによって形成してもよい。   The planned split end 6a can be easily formed by changing the width shape and thickness of the weakening bridge 6 and changing its planar shape (change of the width dimension, etc.), It may be formed by providing perforated holes or slit-shaped cuts.

また、符号７は、弱化ブリッジ６に隣接して設けられた保護突起である。この保護突起７は、弱化ブリッジ６の破断痕が残る部位、すなわち、ベース１ｅの外筒１ｄの外周壁あるいは環状帯３の内周壁のいずれかに一方に設けられるものであって、容器の口頚部先端２から容器用キャップ１を取り外す際に需要者の手指を、弱化ブリッジ６の、先端が尖った破断痕から保護して破断痕による手指への不快な刺激を軽減する。   Reference numeral 7 denotes a protective protrusion provided adjacent to the weakening bridge 6. The protective projection 7 is provided on one of the portions where the fracture marks of the weakened bridge 6 remain, that is, either the outer peripheral wall of the outer cylinder 1d of the base 1e or the inner peripheral wall of the annular belt 3, and When removing the container cap 1 from the cervical tip 2, the user's finger is protected from the rupture mark of the weakened bridge 6 with a sharp tip to reduce unpleasant irritation to the finger due to the rupture mark.

保護突起７の数は、それが弱化ブリッジ６に隣接して存在する限りにおいて種々に変更することができる。また、保護突起７の形態は、凸状とすることもでき、しかも、該保護突起７は、弱化ブリッジ６の上方および下方の少なくとも一方に設けることを可としている。なお、保護突起７が弱化ブリッジ６に隣接して設けられているとは、上記の保護突起６と同様に、数ミリ程度の間でもって離間して位置する場合や弱化ブリッジ６に一体的に連結している場合を含んでいる。   The number of protection projections 7 can be varied in various ways as long as it is adjacent to the weakening bridge 6. Further, the shape of the protective projection 7 can be convex, and the protective projection 7 can be provided on at least one of the upper side and the lower side of the weakening bridge 6. It should be noted that the protective projection 7 is provided adjacent to the weakening bridge 6 as in the case of the protective projection 6 described above, when the protective projection 7 is spaced apart by about several millimeters or integrally with the weakening bridge 6. Includes cases where they are linked.

この実施例では、容器の注出開口２ａを閉塞する天板１ａは、内筒１ｃ、外筒１ｄと同心の環状周壁１ｇおよび連結部１ｈを介して外周縁を内筒１ｃの下端部に一体連結したものを例として示したが、天板１ａは外周縁を内筒１ｃの上端部に一体連結することもできる。また、天板１ａの上面を、内筒１ｃの下端部もしくはそれよりも低い位置に設けることも可能であり、この点については、図示のものに限定されることはない。   In this embodiment, the top plate 1a for closing the dispensing opening 2a of the container has an outer peripheral edge integrated with the lower end portion of the inner cylinder 1c via the inner cylinder 1c, the annular peripheral wall 1g concentric with the outer cylinder 1d and the connecting portion 1h. Although what was connected was shown as an example, the outer periphery of the top plate 1a can also be integrally connected to the upper end part of the inner cylinder 1c. Moreover, it is also possible to provide the upper surface of the top plate 1a in the lower end part or lower position of the inner cylinder 1c, and this point is not limited to the illustrated one.

上記の構成からなる容器用キャップ１においては、図４の矢印で示すように、天面弱化片４、その下方に位置する弱化ブリッジ６をそれぞれ破断させて環状帯３を引き起こし、その環状帯３を引っ張ることで、連結片５を介してベース１ｅの一端部（図では右端部）が引き上げられ、この引き上げにより、容器の口頚部先端２とベース１ｅとのアンダーカット嵌合が上記一端部側から解除されて容器の開封が可能となる。その際、ベース１ｅと環状帯３とをつなぐ天面弱化片４と弱化ブリッジ６はすでに破断しており、容器の口頚部先端２に対する外筒１ｄの嵌合力が低下しているので、容器の口頚部先端２とベース１ｅとの嵌合を容易に解除することができる。   In the container cap 1 having the above-described configuration, as shown by the arrows in FIG. 4, the top surface weakening piece 4 and the weakening bridge 6 positioned therebelow are broken to cause the annular band 3, and the annular band 3 By pulling up, one end portion (right end portion in the figure) of the base 1e is pulled up through the connecting piece 5. By this pulling, the undercut fitting between the mouth neck portion 2 of the container and the base 1e is on the one end side. And the container can be opened. At that time, the top surface weakening piece 4 and the weakening bridge 6 that connect the base 1e and the annular band 3 are already broken, and the fitting force of the outer cylinder 1d with respect to the mouth neck portion 2 of the container is reduced. The fitting between the mouth neck portion 2 and the base 1e can be easily released.

また、かかる構成の容器用キャップ１によれば、抜栓前については、環状帯３が容器の口頸部先端２に対する嵌合力が強化されているので、天面弱化片４、弱化ブリッジ６を破断させて環状帯３を引き起こさない限り容器を開栓することはできず、しかも、容器の正規の開封前に不正な開封が行われた場合には、天面弱化片４の破断が見てとれるので、該天面弱化片４の破断の有無を確認するだけで不正な開封が行われたがどうかを簡単かつ確実に見分けることができる。   Moreover, according to the container cap 1 having such a configuration, the fitting force of the annular band 3 to the mouth neck portion 2 of the container is reinforced before the opening, so that the top weakening piece 4 and the weakening bridge 6 are broken. The container cannot be opened unless the annular band 3 is caused, and if the container is opened illegally before the container is properly opened, the top surface weakening piece 4 is broken. Therefore, it is possible to easily and surely determine whether or not the unauthorized opening has been performed only by confirming whether or not the top surface weakening piece 4 is broken.

なお、本発明の容器用キャップ１は、容器が開封されたのちにおいても、ベース１は初期形状をそのまま維持されるため容器用キャップ１を再利用できる利点がある。   The container cap 1 of the present invention has an advantage that the container cap 1 can be reused even after the container is opened, because the base 1 is maintained in its initial shape.

図５は、本発明に従う容器用キャップ１の他の実施例をその平面について示した図である。かかる容器用キャップ１は、天面弱化片４を、指掛け片３ａが位置する環状帯３の前面側に設けて両端縁４ｄの相互間に破断予定端４ｅを形成した構成のものであり、この場合、弱化ブリッジ６は環状帯３の前面側の側方に設けられることになるが、上掲図１〜４に示した容器用キャップ１と同様に、天面弱化片４の破断の有無を容易に確認できるため、容器の正規の開封前に不正な開封が行われたかどうかの判断がしやすい。   FIG. 5 is a plan view showing another embodiment of the container cap 1 according to the present invention. The container cap 1 has a configuration in which the top surface weakening piece 4 is provided on the front side of the annular band 3 where the finger-hanging piece 3a is located, and the planned break ends 4e are formed between the both end edges 4d. In this case, the weakening bridge 6 is provided on the side of the front surface side of the annular band 3, and whether the top surface weakening piece 4 is broken as in the case of the container cap 1 shown in FIGS. Since it can be easily confirmed, it is easy to determine whether or not unauthorized opening has been performed before the container is properly opened.

本発明の容器用キャップは、天面弱化片４の両端側に隣接して保護突起７と同様の保護突起を設けてもよい。保護突起７と同様の保護突起を設けることにより、容器の口頚部先端２から容器用キャップ１のベース１ｅを離脱させる際に、需要者の手指を、天面弱化片４の先端が尖った破断痕から保護することが可能であり、これによって破断痕による手指への不快な刺激を軽減することができる。   The cap for containers of the present invention may be provided with protective projections similar to the protective projections 7 adjacent to both end sides of the top surface weakening piece 4. By providing a protective projection similar to the protective projection 7, when the base 1e of the container cap 1 is detached from the mouth-neck tip 2 of the container, the user's finger is broken with a sharp tip on the top surface weakening piece 4 It is possible to protect from scratches, which can reduce unpleasant irritation to the fingers due to the fracture marks.

なお、保護突起は、天面弱化片４の破断痕が残る側に設けるのが肝要であり、天面弱化片４の破断痕がベース１ｅの外筒１ｄの外周壁に残る場合には、その部位、すなわち、該外筒１ｄの外周壁に設けられる。   It is important to provide the protective protrusion on the side where the fracture mark of the top surface weakening piece 4 remains, and when the fracture mark of the top surface weakening piece 4 remains on the outer peripheral wall of the outer cylinder 1d of the base 1e, A portion, that is, provided on the outer peripheral wall of the outer cylinder 1d.

本発明によれば、容器の注出開口に対する嵌合力を高めて容器の確実な密封が行える一方、開封時には容易に開封を行うことが可能となる。また、本発明によれば、容器を正規に開封する前に不正な開封が行われたか否かを目視で確実に判断できる。   According to the present invention, the fitting force with respect to the dispensing opening of the container can be increased so that the container can be reliably sealed, while the container can be easily opened at the time of opening. Further, according to the present invention, it is possible to reliably determine visually whether or not unauthorized opening has been performed before the container is properly opened.
