また、打栓の際の上蓋Ｂが下降することで、キャップ基体Ａの蓋係止部７上面と上蓋Ｂの外周壁３１の係止凹部３４下面との当接により、外周壁３１が下部から僅かに外方に拡がり、上蓋Ｂの外周壁３１の内方に密封され、圧縮された空気が係止凹部３４下面のエアー抜き溝３６を介して、係止凹部３４内周と蓋係止部７外周との隙間から外方に排出される。 Further, when the upper lid B is lowered at the time of plugging, the outer peripheral wall 31 is lowered from the lower side by the contact between the upper surface of the lid locking portion 7 of the cap base A and the lower surface of the locking recess 34 of the outer peripheral wall 31 of the upper lid B. Slightly outwardly spread, sealed to the inside of the outer peripheral wall 31 of the upper lid B, and the compressed air passes through the air vent groove 36 on the lower surface of the locking recess 34 and the inner periphery of the locking recess 34 and the lid locking portion. 7 is discharged outward from the gap with the outer periphery.

打栓の際の上蓋Ｂに対する上方からの押圧により、キャップ内の圧縮された空気を排出し、打栓終了時、上蓋Ｂがキャップ基体Ａに対して速やかに復元し、キャップ内を密封するので、キャップ内が僅かに負圧にされる。 The compressed air in the cap is discharged by pressing from the upper side against the upper lid B at the time of the stoppering, and when the stoppering is finished, the upper lid B is quickly restored to the cap base A and the inside of the cap is sealed. The inside of the cap is slightly negative pressure.

キャップ内が僅かに負圧になるので、容器を洗浄のため温水シャワーが行われ、加温され、キャップ内が加圧されても、上蓋Ｂが持ち上がるほどの圧力にはならず、上蓋Ｂが開蓋してしまうことを防止することができる。 Since the inside of the cap is slightly negative pressure, a hot water shower is performed to wash the container, and even if the cap is pressurized and heated, the pressure on the top lid B does not rise so that the top lid B It is possible to prevent the lid from being opened.

また、上蓋Ｂの頂壁３０の内周壁３２内周縁に内圧変形用薄肉部３３が設けられているので、キャップ内の内周壁３２内の室の空気圧が上昇しても、内圧変形用薄肉部３３が変形し、頂壁３０の内圧変形用薄肉部３３より内方のみを上に持ち上げるので、上蓋Ｂ全体が持ち上がることを防止でき、閉蓋を維持させることができる。 Further, since the inner pressure deformation thin portion 33 is provided on the inner peripheral edge of the inner peripheral wall 32 of the top wall 30 of the upper lid B, even if the air pressure in the chamber in the inner peripheral wall 32 in the cap rises, the inner pressure deformation thin portion. Since 33 is deformed and only the inner side of the inner pressure deformation thin portion 33 of the top wall 30 is lifted upward, the entire upper lid B can be prevented from being lifted, and the closed lid can be maintained.

ヒンジキャップの開蓋の際には、上蓋Ｂの摘み片３８を上方に持ち上げる。
摘み片３８が持ち上げられると、外周壁３１の薄肉壁部３１ｂ、特に薄肉壁部３１ｂ内の最薄肉壁部３１ｃは、外周壁３１の他の壁より薄肉となっているので、図４（ａ）に示すように、摘み片３８側から最薄肉壁部３１ｃが変形し、外周壁３１の摘み片３８付近の部分が持ち上げられていく。 When opening the hinge cap, the knob 38 of the upper lid B is lifted upward.
When the knob 38 is lifted, the thin wall portion 31b of the outer peripheral wall 31, particularly the thinnest wall portion 31c in the thin wall portion 31b, is thinner than the other walls of the outer peripheral wall 31, so FIG. ), The thinnest wall portion 31c is deformed from the knob 38 side, and the portion of the outer peripheral wall 31 near the knob 38 is lifted.

外周壁３１の最薄肉壁部３１ｃが変形し、外周壁３１の摘み片３８付近の部分が持ち上げられると、外周壁３１の摘み片３８付近の係止凹部３４の膨出環３５と蓋係止部７の係止突条２２との係止が外される。 When the thinnest wall portion 31c of the outer peripheral wall 31 is deformed and the portion of the outer peripheral wall 31 near the knob 38 is lifted, the bulging ring 35 of the locking recess 34 near the knob 38 of the outer peripheral wall 31 and the lid are locked. The locking of the portion 7 with the locking protrusion 22 is released.

さらに、ヒンジＣを支点に上蓋Ｂが廻動し、摘み片３８側が持ち上げられると、摘み片３８付近から薄肉壁部３１ｂも変形し、図４（ｂ）に示すように、係止凹部３４内周と蓋係止部７外周との嵌合が外され、上蓋Ｂが開蓋される。 Further, when the upper lid B rotates around the hinge C and the knob 38 is lifted, the thin wall portion 31b is also deformed from the vicinity of the knob 38, and as shown in FIG. The fitting between the periphery and the outer periphery of the lid engaging portion 7 is removed, and the upper lid B is opened.

本実施形態のヒンジキャップは、上蓋Ｂの外周壁３１に薄肉壁部３１ｂおよび最薄肉壁部３１ｃを設けていることにより、上蓋Ｂの係止凹部３４とキャップ基体Ａの蓋係止部７との嵌合が強固であっても、開蓋の際、最初に摘み片３８付近の最薄肉壁部３１ｃが変形し、その部分から係止凹部３４の膨出環３５と蓋係止部７の係止突条２２との係止を外していくので、その部分の上蓋Ｂの摘み片３８側の上昇に対する抵抗がなくなり、より弱い力で上蓋Ｂの外周壁３１の摘み片３８側をヒンジＣを支点に上昇させることができ、簡単に開蓋することができる。 The hinge cap of the present embodiment is provided with the thin wall portion 31b and the thinnest wall portion 31c on the outer peripheral wall 31 of the upper lid B, so that the locking recess 34 of the upper lid B and the lid locking portion 7 of the cap base A Even when the fitting is strong, when the lid is opened, the thinnest wall portion 31c in the vicinity of the knob 38 is first deformed, and the bulging ring 35 of the locking recess 34 and the lid locking portion 7 Since the engagement with the locking protrusion 22 is released, there is no resistance to the upward movement of the upper cover B on the side of the knob piece 38, and the knob C side of the outer peripheral wall 31 of the upper cover B is hinged to the hinge C with a weaker force. Can be raised at the fulcrum and can be easily opened.

また、上蓋Ｂの外周壁３１の外周壁凹部３７を凹設する箇所以外の周壁の厚さを厚くし、外周壁３１の下部の保形性を良くすることにより、外周壁３１の係止凹部３４とキャップ基体Ａの蓋係止部７との嵌合を保ち、摘み片３８を持ち上げない限り開蓋しないように設定することができる。 Further, by increasing the thickness of the peripheral wall other than the portion where the outer peripheral wall concave portion 37 of the outer peripheral wall 31 of the upper lid B is provided, and improving the shape retaining property of the lower portion of the outer peripheral wall 31, the locking concave portion of the outer peripheral wall 31 is obtained. 34 can be set so that the lid is not opened unless the knob 38 is raised.

内容物の使用にあたっては、ヒンジキャップを開蓋後、キャップ基体Ａの指掛けリング２７に指を掛け、引張ることにより、弱化部２５を切断させ、除去部２４を隔壁１０から除去して開口し、容器を傾けて、容器内の内容物をキャップ基体Ａの注出筒９を介して注出して使用する。 In using the contents, after opening the hinge cap, a finger is placed on the finger ring 27 of the cap base A and pulled to cut the weakened portion 25, and the removing portion 24 is removed from the partition wall 10 and opened. The container is tilted, and the contents in the container are poured out through the dispensing cylinder 9 of the cap base A and used.

容器を使用後、本発明のヒンジキャップを分別廃棄する際には、まず、本発明のヒンジキャップを開蓋して上蓋Ｂを把持し外方に引っ張ると、キャップ基体Ａの外筒５のヒンジＣとの連設部位が引っ張られて変形し、薄肉連結部２１が引き裂かれて、外筒５の上端からスリット溝１４の底部の位置まで破断される。 When separating and discarding the hinge cap of the present invention after using the container, first, the hinge cap of the present invention is opened, the upper lid B is gripped and pulled outward, the hinge of the outer cylinder 5 of the cap base A The connecting portion with C is pulled and deformed, and the thin connecting portion 21 is torn and is broken from the upper end of the outer cylinder 5 to the position of the bottom of the slit groove 14.

その後、さらに上蓋Ｂを引っ張り、薄肉連結部２１の引き裂きが縦方向薄肉部２０の伝わり、縦方向薄肉部２０の下方部が引き裂かれ、さらに薄肉壁１６が引き裂かれていくとともに、スリット溝１４の周方向薄肉部１５が薄肉連結部２１側から引き裂かれ、外筒５のスリット溝１４の外側および下側が離されていく。 Thereafter, the upper lid B is further pulled, the tearing of the thin-walled connecting portion 21 is transmitted to the vertical thin-walled portion 20, the lower portion of the vertical thin-walled portion 20 is torn, the thin-walled wall 16 is further torn, and the slit groove 14 The circumferential thin portion 15 is torn from the thin connecting portion 21 side, and the outer side and the lower side of the slit groove 14 of the outer cylinder 5 are separated.

外筒５の周方向薄肉部１５が切断され、外筒５のスリット溝１４の外側および下側が離されていくことにより、容器の容器口部１外周と、キャップ基体Ａの外筒５の内周および係合突条１３との嵌合が外されていく。
さらに、上蓋Ｂまたは切り離された外筒５を上に引っ張ると、容器口部１からキャップ基体Ａを簡単に外すことができ、キャップと容器を分別廃棄することができる。 The outer thin portion 15 in the circumferential direction of the outer cylinder 5 is cut, and the outer and lower sides of the slit groove 14 of the outer cylinder 5 are separated from each other, so that the outer periphery of the container mouth 1 of the container and the inner cylinder 5 of the cap base A The engagement with the circumference and the engagement protrusion 13 is released.
Further, when the upper lid B or the separated outer cylinder 5 is pulled upward, the cap base A can be easily removed from the container mouth portion 1, and the cap and the container can be separated and discarded.

上記実施例では、上蓋Ｂの外周壁３１のヒンジＣの反対側の外周に、外周壁凹部３７および変形用凹部３９が中央から両側の所定の位置までの範囲に形成されているが、外周壁３１に薄肉壁部３１ｂおよび最薄肉壁部３１ｃを形成し、開蓋の際に変形させることができれば良いので、外周壁３１を簡単に変形させる範囲、例えば、少なくとも、図１に示す、摘み片３８の横幅ほどの範囲で外周壁凹部３７および変形用凹部３９を凹設し、薄肉壁部３１ｂおよび最薄肉壁部３１ｃを形成するようにしても良い。 In the above embodiment, the outer peripheral wall recess 37 and the deformation recess 39 are formed on the outer periphery of the outer peripheral wall 31 of the upper lid B opposite to the hinge C in a range from the center to a predetermined position on both sides. The thin wall portion 31b and the thinnest wall portion 31c may be formed in 31 and can be deformed when the lid is opened. Therefore, a range in which the outer peripheral wall 31 is easily deformed, for example, at least the knob shown in FIG. The outer peripheral wall concave portion 37 and the deformation concave portion 39 may be provided in a range of about 38 lateral widths to form the thin wall portion 31b and the thinnest wall portion 31c.

また、上記実施例では、外周壁３１のヒンジＣの反対側の外周に、外周壁凹部３７内に変形用凹部３９を凹設し、外周壁３１の壁の厚さが、薄肉壁部３１ｂの厚さに比べ薄肉となる変形薄肉部３１ｃとしたが、外周壁３１の係止凹部３４の内周の膨出環３５の上端部から上端の範囲と外周壁凹部３７との間の壁の厚さは、他の外周壁凹部３７の薄肉壁部３１ｂに比べ薄肉となり、摘み片３８を持ち上げた際、薄肉の部分が簡単に変形して外周壁３１の摘み片３８付近の係止凹部３４の膨出環３５と蓋係止部７の係止突条２２との係止を外し、弱い力で上昇させることができるので、外周壁３１の外周壁凹部３７内にさらに変形用凹部３９を凹設しなくてもよい。 Moreover, in the said Example, the recessed part 39 for a deformation | transformation is recessedly provided in the outer peripheral wall recessed part 37 in the outer periphery on the opposite side to the hinge C of the outer peripheral wall 31, and the thickness of the wall of the outer peripheral wall 31 is thin wall part 31b.

摘み片４６を持ち上げると、外周壁４３の最薄肉壁部４３ｃは、外周壁４３の他の壁より薄肉となっているので、第１実施例と同様に、摘み片４６側から最薄肉壁部４３ｃが変形し、外周壁４３の摘み片４６付近の部分が持ち上げられていく。 In order to open the hinge cap of the present embodiment, the sealing plate 49 is rotated from the state shown in FIG. 6 to release the engagement between the seal locking portion 49a and the knob piece 46, and the weakened connecting piece 51 is The sealing plate 49 is removed by cutting.
Next, when the hinge cap is opened, the knob 46 of the upper lid Ba is lifted upward.
When the knob 46 is lifted, the thinnest wall 43c of the outer peripheral wall 43 is thinner than the other walls of the outer peripheral wall 43. Therefore, as in the first embodiment, the thinnest wall from the knob 46 side. 43c deform | transforms and the part near the knob | pick piece 46 of the outer peripheral wall 43 is lifted.

外周壁４３の最薄肉壁部４３ｃが変形し、外周壁４３の摘み片４６付近の部分が持ち上げられると、外周壁４３の摘み片４６付近の係止凹部３４の膨出環３５と蓋係止部７の係止突条２２との係止が外される。
さらに、ヒンジＣを支点に上蓋Ｂａが廻動し、摘み片４６側が持ち上げられると、摘み片４６付近から薄肉壁部４３ｂも変形し、係止凹部３４内周と蓋係止部７外周との嵌合が外され、上蓋Ｂａが開蓋される。 When the thinnest wall portion 43c of the outer peripheral wall 43 is deformed and the portion of the outer peripheral wall 43 near the knob 46 is lifted, the bulging ring 35 of the locking recess 34 near the knob 46 and the lid is locked. The locking of the portion 7 with the locking protrusion 22 is released.
Further, when the upper lid Ba rotates around the hinge C and the knob piece 46 side is lifted, the thin wall portion 43b is also deformed from the vicinity of the knob piece 46, and the inner periphery of the locking recess 34 and the outer periphery of the lid locking portion 7 are deformed. The fitting is released, and the upper lid Ba is opened.

本実施例のヒンジキャップは、上蓋Ｂａの外周壁４３に薄肉壁部４３ｂおよび最薄肉壁部４３ｃを設けていることにより、上蓋Ｂａの係止凹部３４とキャップ基体Ａａの蓋係止部７との嵌合が強固であっても、開蓋の際、最初に摘み片４６付近の最薄肉壁部４３ｃが変形し、その部分から係止凹部３４の膨出環３５と蓋係止部７の係止突条２２との係止を外していくので、その部分の上蓋Ｂの摘み片４６側の上昇に対する抵抗がなくなり、より弱い力で上蓋Ｂの外周壁４３の摘み片４６側をヒンジＣを支点に上昇させることができ、簡単に開蓋することができる。 The hinge cap of the present embodiment is provided with the thin wall portion 43b and the thinnest wall portion 43c on the outer peripheral wall 43 of the upper lid Ba, so that the locking recess 34 of the upper lid Ba and the lid locking portion 7 of the cap base Aa Even when the fitting is strong, when the lid is opened, the thinnest wall portion 43c near the knob 46 is first deformed, and the bulging ring 35 of the locking recess 34 and the lid locking portion 7 are Since the engagement with the locking protrusion 22 is released, there is no resistance to the lift of the upper cover B on the side of the knob piece 46, and the knob C side of the outer peripheral wall 43 of the upper lid B is hinged with a weaker force. Can be raised at the fulcrum and can be easily opened.

さらに、下端壁部４３ａの上面には、くぼみ部４８が変形用凹部４７に隣接して形成されていることにより、開蓋の際に、摘み片４６を持ち上げると、最薄肉壁部４３ｃの変形に続いて、下方に隣接する薄肉壁部４３ｂが変形し、外周壁４３の摘み片４６付近の部分が持ち上げられ、外周壁４３の係止凹部３４の膨出環３５と蓋係止部７の係止突条２２との係止が外されていくので、より弱い力で簡単に開蓋することができる。 Further, since the recess 48 is formed adjacent to the deformation recess 47 on the upper surface of the lower end wall 43a, when the knob 46 is lifted when the lid is opened, the thinnest wall 43c is deformed. Subsequently, the thin wall portion 43b adjacent to the lower side is deformed, the portion of the outer peripheral wall 43 near the knob 46 is lifted, and the bulging ring 35 of the locking recess 34 of the outer peripheral wall 43 and the lid locking portion 7 Since the locking with the locking protrusion 22 is released, the lid can be easily opened with a weaker force.

また、本実施例のヒンジキャップは、上蓋Ｂａの外周壁４３の係止凹部３４の内側に、キャップ基体Ａａの蓋係止部７の内周と係合する環状凸部４４が形成され、環状凸部４４と係止凹部３４がキャップ基体Ａａの蓋係止部７を挟むように嵌合していることにより、上蓋Ｂａとキャップ基体Ａａとを強固に嵌合させることができるのみならず、上蓋Ｂａを押し潰すような力が加わっても、外周壁４３の下端部が広がって不用意に開蓋するのを防止することができる。
その他の作用効果は、上記第１実施例と同じである。 Further, in the hinge cap of the present embodiment, an annular convex portion 44 that engages with the inner periphery of the lid engaging portion 7 of the cap base Aa is formed inside the engaging concave portion 34 of the outer peripheral wall 43 of the upper lid Ba, and the annular cap 44 is formed in an annular shape. By fitting the convex portion 44 and the locking recess 34 so as to sandwich the lid locking portion 7 of the cap base Aa, not only can the upper lid Ba and the cap base Aa be firmly fitted, Even if a force that crushes the upper lid Ba is applied, it is possible to prevent the lower end portion of the outer peripheral wall 43 from spreading and inadvertently opening the lid.
Other functions and effects are the same as those of the first embodiment.

本発明は、上蓋の外周壁のヒンジの反対側のキャップ基体の蓋係止部外周に嵌合する外周壁の係止凹部の内周がある壁部を変形可能な薄肉壁部とすることで、ヒンジキャップを開蓋する際に、該薄肉壁部を簡単に変形させ、その部分から外周壁の係止凹部の膨出環と蓋係止部との係止を外していくことができるので、上蓋とキャップ基体とが強固に嵌合していても簡単に開蓋することができ、上蓋の形状にかかわらず、各種の容器のヒンジキャップとして、広く利用することができる。 According to the present invention, the wall portion having the inner periphery of the engaging recess of the outer peripheral wall fitted to the outer periphery of the cap engaging portion of the cap base on the opposite side of the hinge of the outer peripheral wall of the upper lid is formed into a deformable thin wall portion.
