図１および図２は、本発明の閉止装置の一例を示すもので、この閉止装置は、容器２０と、その口部２１に装着される合成樹脂製キャップ１とから構成されている。
容器２０は、ポリエチレンテレフタレート（ＰＥＴ）などの合成樹脂、ガラス、金属などからなるものを使用することができる。 FIG. 1 and FIG. 2 show an example of the closing device of the present invention, and this closing device is composed of a container 20 and a synthetic resin cap 1 attached to its mouth 21.
The container 20 may be made of a synthetic resin such as polyethylene terephthalate (PET), glass, metal or the like.

キャップ１は、天板部２とその周縁部２ｂから垂下した筒部３とを有するキャップ本体４を備えている。
筒部３は、水平スコア６（弱化線）によって、主部８と、複数のブリッジ７によって主部８の下端に連結されたタンパーエビデンスリング部９（ＴＥリング部）とに区画されている。
主部８の内面には、容器口部２１の外面２１ｃに形成された雄ネジ２２に螺合するネジ部１０が形成されている。
ＴＥリング部９の内壁面には、キャップ１を開栓する際に容器口部２１の環状凸部２３に係止してＴＥリング部９の移動を阻止する係止手段であるタブ１１が設けられている。タブ１１は、起伏可能な板状に形成されている。 The cap 1 includes a cap body 4 having a top plate portion 2 and a cylindrical portion 3 hanging from the peripheral edge portion 2b.
The cylindrical part 3 is divided into a main part 8 by a horizontal score 6 (weakening line) and a tamper evidence ring part 9 (TE ring part) connected to the lower end of the main part 8 by a plurality of bridges 7.
On the inner surface of the main portion 8, a screw portion 10 that is screwed into a male screw 22 formed on the outer surface 21 c of the container mouth portion 21 is formed.
The inner wall surface of the TE ring portion 9 is provided with a tab 11 that is a locking means for locking the annular ring 23 of the container mouth portion 21 to prevent the movement of the TE ring portion 9 when the cap 1 is opened. It has been. The tab 11 is formed in a plate shape that can be raised and lowered.

天板部２の内面２ａには、容器口部２１内に嵌入される環状の内側シール突起１２が、下方に向けて突出形成されている。
内側シール突起１２の先端部外面には、容器内面２１ａに当接する環状の当接凸部１２ａが形成されている。内側シール突起１２は、容器口部２１内に嵌入した際に、当接凸部１２ａが容器内面２１ａに隙間なく当接し、容器２０を密封できるように形成されている。 On the inner surface 2 a of the top plate portion 2, an annular inner seal protrusion 12 that is fitted into the container mouth portion 21 is formed so as to protrude downward.
On the outer surface of the distal end portion of the inner seal protrusion 12, an annular contact convex portion 12a that contacts the container inner surface 21a is formed. The inner seal protrusion 12 is formed so that the contact protrusion 12a can contact the inner surface 21a of the container without a gap when the inner seal protrusion 12 is fitted into the container mouth portion 21, and the container 20 can be sealed.

天板部２には、内側シール突起１２より外方に、容器口部２１の開口端面２１ｂに当接する開口端シール突起１３と、容器口部２１の外面２１ｃに当接する外側シール突起１４とが下方に向けて突出形成されている。   The top plate portion 2 has an opening end seal projection 13 that contacts the opening end surface 21b of the container mouth portion 21 and an outer seal projection 14 that contacts the outer surface 21c of the container mouth portion 21 outward from the inner seal projection 12. It protrudes downward.

天板部２には、溝部１５が形成されている。
溝部１５は、直線状の第１溝１６と、これに対しほぼ垂直に交差する直線状の第２溝１７とからなる十字状に形成されている。
第１および第２溝１６、１７は、その端部１６ａ、１７ａが天板部２の周縁部２ｂの近傍に達するように形成されている。
第１および第２溝１６、１７は、端部１６ａ、１７ａから、天板部２の中央部２ｃに近づくに従って徐々に深くなるように形成され、中央部２ｃで最も深くなっている。
第１および第２溝１６、１７の交点１８は、天板部２の中央部２ｃに位置している。 A groove 15 is formed in the top plate 2.
The groove portion 15 is formed in a cross shape including a linear first groove 16 and a linear second groove 17 intersecting substantially perpendicularly thereto.
The first and second grooves 16 and 17 are formed so that the end portions 16 a and 17 a reach the vicinity of the peripheral edge portion 2 b of the top plate portion 2.
The first and second grooves 16 and 17 are formed so as to gradually become deeper from the end portions 16a and 17a toward the central portion 2c of the top plate portion 2, and are deepest at the central portion 2c.
An intersection 18 of the first and second grooves 16 and 17 is located in the central portion 2 c of the top plate portion 2.

溝部１５の最深部における天板部２の厚さは、０．０５〜０．５ｍｍ（好ましくは０．２〜０．５ｍｍ）とするのが好適である。
この厚さが上記範囲を下回る場合には、溝部１５における天板部２の強度が低くなり、天板部２が破損しやすくなる。厚さが上記範囲を越える場合には、容器内圧上昇時に天板部２が開裂しにくくなる。
この厚さは、容器内圧が所定値（例えば０．４ＭＰａ（ゲージ圧））以上となったときに天板部２が開裂するように設定することができる。
なお、本発明では、溝部の形状は十字状に限らず、直線状としてもよい。この場合でも、溝部は中央部２ｃを通るように形成される。また、溝部は３本以上の直線状の溝からなるものであってもよい。 The thickness of the top plate portion 2 at the deepest portion of the groove portion 15 is suitably 0.05 to 0.5 mm (preferably 0.2 to 0.5 mm).
When this thickness is less than the above range, the strength of the top plate portion 2 in the groove portion 15 is lowered, and the top plate portion 2 is easily damaged. When the thickness exceeds the above range, the top plate portion 2 is difficult to be cleaved when the internal pressure of the container is increased.
This thickness can be set such that the top plate 2 is cleaved when the internal pressure of the container becomes a predetermined value (for example, 0.4 MPa (gauge pressure)) or more.
In the present invention, the shape of the groove is not limited to a cross shape, and may be a straight shape. Even in this case, the groove portion is formed so as to pass through the central portion 2c. The groove portion may be composed of three or more linear grooves.

キャップ１を構成する合成樹脂材料としては、ポリプロピレンまたはポリエチレンを含む材料を挙げることができる。   Examples of the synthetic resin material constituting the cap 1 include materials containing polypropylene or polyethylene.

以下、図２ないし図４を参照して、キャップ１の使用方法を説明する。
図２に示すように、内溶液を充填した容器２０の口部２１にキャップ１を装着することによって、内側シール突起１２は容器口部２１内に挿入される。
内側シール突起１２は、当接凸部１２ａにおいて容器内面２１ａに当接し、この部分をシールする。これによって容器２０が密封される。
また、ＴＥリング部９に設けられたタブ１１は、雄ネジ２２の直下に設けられた環状の環状凸部２３を乗り越え、環状凸部２３の下方に達する。 Hereinafter, a method of using the cap 1 will be described with reference to FIGS.
As shown in FIG. 2, by attaching the cap 1 to the mouth portion 21 of the container 20 filled with the inner solution, the inner seal protrusion 12 is inserted into the container mouth portion 21.
The inner seal projection 12 abuts on the container inner surface 21a at the abutment convex portion 12a and seals this portion. As a result, the container 20 is sealed.
Further, the tab 11 provided on the TE ring portion 9 gets over the annular annular protrusion 23 provided immediately below the male screw 22 and reaches below the annular protrusion 23.

容器口部２１に装着されたキャップ１を開栓方向に回すと、キャップ１が上昇し、内側シール突起１２が容器口部２１から引き抜かれ、容器２０の密封が解除される。
この際、ＴＥリング部９内面に設けられたタブ１１が環状凸部２３下部に係止することから、主部８は回転に従って上昇する一方、ＴＥリング部９は上方への移動が阻止される。その結果、キャップ１の主部８とＴＥリング部９とを連結しているブリッジ７に引張力が作用し、ブリッジ７が破断され、ＴＥリング部９が主部８から切り離される。このＴＥリング部９の切り離しによって、キャップ１が開栓されたことが明示される。 When the cap 1 attached to the container mouth portion 21 is turned in the opening direction, the cap 1 is raised, the inner seal protrusion 12 is pulled out from the container mouth portion 21, and the sealing of the container 20 is released.
At this time, since the tab 11 provided on the inner surface of the TE ring portion 9 is locked to the lower portion of the annular convex portion 23, the main portion 8 rises as it rotates, while the TE ring portion 9 is prevented from moving upward. . As a result, a tensile force acts on the bridge 7 connecting the main portion 8 of the cap 1 and the TE ring portion 9, the bridge 7 is broken, and the TE ring portion 9 is separated from the main portion 8. It is clearly shown that the cap 1 is opened by the separation of the TE ring portion 9.

キャップ１をいったん開栓した後に再栓した際には、内容液の発酵などにより容器２０の内圧が非常に高くなる（例えば０．４ＭＰａ（ゲージ圧）以上となる）ことがある。
容器２０内の圧力が上昇すると、この容器内圧によって、天板部２に対し上方への力が加えられる。 When the cap 1 is once opened and then re-opened, the internal pressure of the container 20 may become very high (for example, 0.4 MPa (gauge pressure) or more) due to fermentation of the content liquid.
When the pressure in the container 20 rises, an upward force is applied to the top plate portion 2 by the container internal pressure.

図３に示すように、容器内圧により天板部２に上方への力が加えられると、天板部２は上方に膨出変形する。これによって、天板部２には引張力が加えられる。
図４に示すように、さらに容器内圧が高まり、天板部２の膨出変形が大きくなると、天板部２に加えられる引張力が大きくなる。
天板部２の膨出変形の際には、中央部２ｃから周縁部２ｂに向けた引張力が天板部２に加えられるため、引張力は中央部２ｃに集中して作用する。このため、溝部１５は交点１８またはその近傍から開裂する。
天板部２の開裂によって生じた隙間１９を通して容器２０内のガスが外部に排出される。 As shown in FIG. 3, when an upward force is applied to the top plate portion 2 due to the internal pressure of the container, the top plate portion 2 bulges and deforms upward. As a result, a tensile force is applied to the top plate 2.
As shown in FIG. 4, when the internal pressure of the container further increases and the bulging deformation of the top plate portion 2 increases, the tensile force applied to the top plate portion 2 increases.
When the top plate portion 2 is bulged and deformed, a tensile force from the central portion 2c toward the peripheral portion 2b is applied to the top plate portion 2, so that the tensile force acts on the central portion 2c. For this reason, the groove part 15 is cleaved from the intersection 18 or its vicinity.
The gas in the container 20 is discharged to the outside through the gap 19 generated by the cleavage of the top plate 2.

上記キャップ１は、次の効果を奏する。
（１）キャップ１では、天板部２に、容器内圧上昇時に天板部２を開裂させる溝部１５が形成され、溝部１５が天板部２の中央部２ｃを通るように形成されている。
天板部２の膨出変形時には、中央部２ｃに大きな引張力が作用するため、容器内圧上昇時に、溝部１５で天板部２を確実に開裂させることができる。
従って、容器２０の内圧が過度に上昇するのを防ぐことができる。
（２）キャップ１では、溝部１５が、互いに交差する第１および第２溝１６、１７からなるので、天板部２が膨出変形する際には、溝１６に垂直な方向、および溝１７に垂直な方向の引張力が天板部２に作用する。このため、交点１８には大きな引張力が加えられる。
従って、天板部２が交点１８またはその近傍において確実に開裂される。
（３）キャップ１では、第１および第２溝１６、１７の交点１８が天板部２のほぼ中央部２ｃに位置するので、天板部２を交点１８で確実に開裂させることができる。
（４）キャップ１では、溝部１５は、天板部２の中央部２ｃで最も深くなるように形成されている。
従って、膨出変形時に大きな引張力が加えられる中央部２ｃにおいて、天板部２を確実に開裂させることができる。 The cap 1 has the following effects.
(1) In the cap 1, a groove portion 15 is formed in the top plate portion 2 to cleave the top plate portion 2 when the internal pressure of the container increases, and the groove portion 15 is formed so as to pass through the central portion 2 c of the top plate portion 2.
When the top plate portion 2 is bulged and deformed, a large tensile force acts on the central portion 2c, so that the top plate portion 2 can be reliably cleaved by the groove portion 15 when the internal pressure of the container is increased.
Therefore, it is possible to prevent the internal pressure of the container 20 from rising excessively.
(2) In the cap 1, the groove portion 15 is composed of the first and second grooves 16 and 17 intersecting each other. Therefore, when the top plate portion 2 bulges and deforms, the direction perpendicular to the groove 16 and the groove 17 A tensile force in a direction perpendicular to the top plate portion 2 acts on the top plate portion 2. For this reason, a large tensile force is applied to the intersection 18.
Therefore, the top plate 2 is reliably cleaved at the intersection 18 or in the vicinity thereof.
(3) In the cap 1, the intersection 18 of the first and second grooves 16, 17 is located at substantially the center 2 c of the top plate 2, so that the top 2 can be reliably cleaved at the intersection 18.
(4) In the cap 1, the groove portion 15 is formed so as to be deepest at the central portion 2 c of the top plate portion 2.
Therefore, the top plate portion 2 can be reliably cleaved at the central portion 2c where a large tensile force is applied during bulging deformation.

上記閉止装置は、果汁飲料、茶飲料、コーヒー飲料、炭酸飲料等の飲料を容器２０に充填し、口部２１にキャップ１を装着することによって、飲料が充填された容器詰め飲料とすることができる。   The closing device may be a container-packed beverage filled with beverages by filling the container 20 with beverages such as fruit juice beverages, tea beverages, coffee beverages, carbonated beverages, and attaching the cap 1 to the mouth portion 21. it can.
