Description

【０００１】
【発明の属する技術分野】
この発明は、封緘手段を有する摺り切り片付き蓋及びこの蓋を嵌装固定した縦溶接缶を目的とした摺り切り片付き蓋及び蓋付き缶に関する。
【０００２】
【従来の技術】
従来缶口部を覆う仕切り板の切り取り縁を摺り切り縁とした缶は知られていた（実公昭５３−４７００２号）。
【０００３】
【発明により解決しようとする課題】
前記従来の仕切り板付き缶は、一旦開口すると、開口部を塞ぐことができないので、外蓋を必要とする問題点があった。また従来の缶は、缶口部内壁へ環状鍔を一体的に設けるには、別製の筒口部を缶口部へ連設していたので、缶の製造を複雑化し、製造価格の高騰を招く問題点もあった。
【０００４】
【課題を解決する為の手段】
この発明は、帽状蓋の頂板下面へ摺り切り片を設けると共に、帽状蓋を固定蓋部と開閉蓋部とに分け、使用時には開閉蓋部を開くようにし、外蓋不用の摺り切り片付き蓋を得て、前記従来の問題点を解決したのである。また缶体は缶胴材を縦に溶接接合することにより、缶口部へ内鍔を一体成形しても、加工に無理がなく、良好に仕上げることができる。
【０００５】
即ちこの発明の蓋は、上端カール部が内巻きに形成されている缶口部へ嵌装掛止できる合成樹脂製の帽状蓋であって、円形の頂板と側壁とからなり、該帽状蓋を缶口部への固定蓋部と、開閉蓋部とに二分する為の側壁切断部を側壁に有すると共に、当該側壁切断部を直線状に結ぶ位置に直線状の開閉連結部を有し、前記固定蓋部の前記直線状の開閉連結部が形成されている直線縁に近接して、前記固定蓋部の下面に摺り切り片が下向きに突設されており、前記側壁の下縁内側に缶口部の外側壁に嵌装される嵌装部が形成され、掛止突部を有していて缶口部の上端カール部と掛止する複数個の突片が、帽状蓋の頂板の下面に、その外周縁に近接して所定間隔で缶口部の内面位置に沿うように突設され、前記開閉蓋部における側壁の嵌装部の一部が切り取り除去可能に形成されていることを特徴とする摺り切り片付き蓋である。
図１、２、３、４において、符号５で示されている開封用の切り取り部５が、前記において、切り取り除去可能に形成されている開閉蓋部における側壁の嵌装部の一部に相当する。
【０００７】
また蓋付き缶の発明は、缶体の缶口部の側壁を内方へ屈曲して環状鍔が形成され、当該環状鍔の上部側壁に環状凸部が形成され、当該環状鍔の上部側壁の上端に上端カール部が内巻きに形成されている缶口部へ、前記本発明の摺り切り片付き蓋の、前記側壁の下縁内側に形成されている嵌装部を前記環状凸部に嵌装すると共に、前記突片の掛止突部を缶口部の上端カール部に掛止することにより、前記本発明の摺り切り片付き蓋を被冠してなる蓋付き缶である。ここで、缶口部は、缶胴材の縦の両端部を重ねて溶接接合したものである。
【０００８】
前記のように構成したので、蓋には封緘手段を保有しており、これを封緘開放手段により開封することにより、蓋の開閉蓋部を容易に開閉することができる。
【０００９】
前記において、固定蓋部の大きさを蓋の１／２以下にすると、その直線縁が弦となり、開閉蓋部を開いて直立した場合に、開閉蓋部の側壁下縁が、缶口側壁の上端部へ重なり、開閉蓋部の自動復帰を防止することができる。
【００１０】
前記缶口側壁の上端部は内側へカールしており、蓋の頂板下面に突設した掛止片の突条部と掛止し、固定蓋部が外れないように配慮すると共に、開閉蓋部の閉塞状態を安定化するようにしてある。
【００１１】
【発明の実施の形態】
この発明は、帽状蓋を固定蓋部と、開閉蓋部とに２分し、前記固定蓋部の内側に摺り切り片を弦状に設け、開閉蓋部の側壁へ封緘手段を設けた摺り切り片付き蓋である。
【００１２】
また前記摺り切り片付き蓋を、缶胴部が縦に電気溶接された缶に嵌装固定したものである。従って外蓋が不用になり、構造を簡単にし、製造を容易にした蓋付き缶である。
【００１３】
【実施例１】
この発明の実施例を図１、２、３、４に基づいて説明する。円筒形の缶口部４へ嵌装できる合成樹脂製の帽状蓋１の側壁に、前記帽状蓋１を固定蓋部１ａと、開閉蓋部１ｂとに分ける為の切断部２を直径対称的に設ける。前記固定蓋部１ａは、缶口部４へ嵌装する円弧部１ｃと、開閉蓋部１ｂと連結する直線状の連結部１ｄにより形成されており、前記固定蓋部１ａの下面へ、前記連結部１ｄに近接し、かつ平行して摺り切り片３を下向きに突設する。
【００１４】
前記開閉蓋部１ｂは、缶口部４へ嵌装する円弧部１ｅと、固定蓋部１ａと連結する直線状の連結部１ｄにより成形されており、前記円弧部１ｅの嵌装部には、開封用の切り取り部５と、その摘み片５ａとが設けられ、該切り取り部５には、側壁から切り取る為の切込み６ａと、薄肉部６ｂ、５ｂが設けてあり、更に切り取り部５を切り取った後には、摘み片７を形成する為に所定間隔で切込み８、８が設けてある。
【００１５】
前記帽状蓋１の側壁の下縁内側には、缶口部４の外側壁の環状凸部４ａに嵌装する為の嵌装部９が設けてあり、前記帽状蓋１の頂板の下面には、外周縁に近接して、缶口部４の上端カール部４ｂと掛止する数個の突片１０、１０が所定間隔で、缶口部４の内面位置に沿うように突設され、前記突片１０、１０には掛止突部１０ａ、１０ａが設けてある（図１、２）。
【００１６】
前記実施例において、図１中摘み片５ａを矢示１４の方向へ引張ると、連結薄膜５ｂ、６ｂが切断されるので、切り取り部５を矢示１５の方向へ取り外すことができる。切り取り部５を取った残りの摘み片７を外側へ引張ると、摘み片７の両側の切込み８、８から切断され、摘み易くなる。
【００１７】
そこで摘み片７を外側の斜上方へ矢示２５のように引張れば、開閉蓋部１ｂを図２のように持ち上げることができる。この場合に、開閉蓋部１ｂの側壁２９の基部１ｆが缶口部側壁上（カール部上）へ乗り上がるので（図２）。開閉蓋部１ｂは、その状態を保つことができる。
【００１８】
図４の実施例は、前記実施例と封緘手段のみを異にするものであって、摘み片１１ａと、切り取り部１１からなり、切り取り部１１の基部上側１１ｂは側壁と連結してあり、切り取り部１１の縦辺１１ｄは切断される。
【００１９】
前記実施例において、摘み片１１ａを矢示１６の方向へ引張れば、摘み片１１ａが側壁から分離される。そこで摘み片１１ａを矢示１７の方向へ引張れば、切り取り部１１の両側の切込み１１ｃから切り取ることができるので、封緘を解除できる。
【００２０】
次に図５の実施例は、前記２つの実施例と封緘手段のみを異にしているものであって、摘み片１２ａを逆Ｌ字状に上向きに屈曲し、これを連結薄膜１２ｂで側壁と連結し、摘み片１２ａの連結部の両側に切込み１３が設けてある。
【００２１】
従って摘み片１２ａを矢示１８の方向へ引張って、連結薄膜１２ｂを破断し、ついで矢示１９の方向に引上げると、切り取り部１２は切込み１３と、薄肉部１３ａから上方へ切り取られ、缶口部４との掛止が解けるので（封緘解除）、開閉蓋部１ｂを図５中鎖線図示のように引上げることができる。この場合に、開閉蓋部１ｂの側壁２９の基部１ｆが、缶口上端縁に乗り上るので、開閉蓋部１ｂは、直立状態を保つことができる。次に前記基部１ｆを缶口上端縁から外せば、開閉蓋部１ｂを缶口部４へ嵌装することができる。
【００２２】
前記実施例において、帽状蓋１の頂板２８の下面には、その外周縁に接近して数個の突片１０、１０がほぼ等間隔で設けられ、突片１０の下端内側には、掛止突部１０ａが設けられてあって、缶口部４の上端カール部４ｂと確実に掛止しているので、帽状蓋１は確実に被冠固定される。また帽状蓋１の側壁２９は、缶口部の環状凸部４ａに緊密に嵌装固定しているので、そのままでは開蓋不可能（封緘確実）であるが、帽状蓋１の側壁２９の一部を破断（切取り部除去）すれば、側壁の変形が容易となり、開蓋可能となる。然し乍ら前記突片１０の掛止により、被冠状態を確実に保持し、外蓋の役目を果すことができる。
【００２３】
【実施例２】
この発明の他の実施例を図３、６、７、８に基づいて説明する。缶体２０の缶口部４の側壁に環状凹入部を形成し、これを扁平に加圧成形して環状鍔２１を形成し、該環状鍔２１に透明合成樹脂その他の不通気性の仕切り板２２の周縁部を被着して密閉し、前記環状鍔２１の上部側壁へ環状凸部４ａを設けると共に、側壁上端部へ上端カール部４ｂを内巻きに設けて缶２３を構成する。
【００２４】
前記缶２３の缶口部４へ実施例１の摺り切り片付きの帽状蓋１を嵌装し、封緘固定すれば、この発明の蓋付き缶２４ができる。
【００２５】
前記実施例の蓋付き缶２４には、缶底側から内容物（例えば粉乳）を充填した後、底板を固定し、例えば粉乳缶として販売される。
【００２６】
この蓋付き缶２４から内容物を取り出すには、摘み片５ａを引張り、切り取り部５を取り外して開封し、ついで摘み片７を引張って開閉蓋部１ｂを開ける。次に仕切り板２２の摘み片２６を引張って仕切り板２２を取り除けば、内容物を取り出すことができる。
【００２７】
この場合に、内容物をスプーンに盛り、これを摺り切り片３で摺り切れば、スプーン一杯の量が正確に計量され、取り出し量を規制することができるので、内容物を過不足なく使用することができる。
【００２８】
前記のようにして内容物を取り出したならば、開閉蓋部を倒して缶口部へ嵌装し、気密を保つことができるので、別製の外蓋は不用である。従って前記実施例によれば、封緘完備で外蓋の必要もなく、構造簡単で内容物の保持が確実な缶を提供することができる。
【００２９】
【実施例３】
図９〜図１２に基づきこの発明の他の実施例を説明する。
【００３０】
実施例１と同様に、円筒形の缶口部４へ嵌装できる合成樹脂製の帽状蓋１の側壁に、前記帽状蓋１を固定蓋部１ａと、開閉蓋部１ｂとに分ける為の切断部２を直径対称的に設け、前記固定蓋部１ａは、缶口部４へ嵌装する円弧部１ｃと、開閉蓋部１ｂと連結する直線状の連結部１ｄにより形成されており、前記固定蓋部１ａの下面へ、前記連結部１ｄに近接し、かつ平行して摺り切り片３を下向きに突設されてなる。また、前記開閉蓋部１ｂは、缶口部４へ嵌装する円弧部１ｅと、固定蓋部１ａと連結する直線状の連結部１ｄにより成形されており、前記円弧部１ｅの嵌装部には、開封用の切り取り部５と、その摘み片５ａとが設けられ、該切り取り部５には、側壁から切り取る為の切込み６ａと、薄肉部６ｂ、５ｂが設けてあり、更に切り取り部５を切り取った後には、摘み片７を形成する為に所定間隔で切込み８、８が設けてある。また、前記帽状蓋１の側壁の下縁内側には、缶口部４の外側壁の環状凸部４ａに嵌装する為の嵌装部９が設けてあり、前記帽状蓋１の頂板の下面には、外周縁に近接して、缶口部４の上端カール部４ｂと掛止する数個の突片１０、１０が、缶口部４の内面に沿った位置に、所定間隔で突設され、前記突片１０、１０には掛止突部１０ａ、１０ａが設けてある（図１、２）。
【００３１】
この実施例では、固定蓋部１ａの大きさを帽状蓋１の２分の１以下として、直線縁（摺り切り片３）が弦状となっている。実施例１と同様に、開閉蓋部１ｂを引き起こした際に、前記開閉蓋部１ｂの側壁の基部（摺りきり片３側）１ｆが、缶口部側壁上に乗り上がるように形成されているが（図９（ａ）、図２）、該基部１ｆを内面側が凹となるように薄肉にして、内面側に段部２７が形成されている。従って、該基部１ｆの外面側の端縁１ｇは内面側の端縁１ｈより、固定蓋部１ａ側に突出させて形成され、内面側の端縁１ｈが段部２７となっている（図９（ｂ）（ｃ））。
【００３２】
この場合、前記開閉蓋部１ｂの側壁の基部１ｆが、缶口部側壁上に乗り上がるように引き上げた際に、段部２７（内面側の端縁１ｈ）が缶口部側壁上縁に当接して、実施例１と同様に、開閉蓋部１ｂの戻りを防止できる。また、この時、基部１ｆの外面側の端縁１ｇは缶口側壁の外面側にあり、基部１ｆが缶口内に入り込むことを防止する。従って、開閉蓋部１ｂを閉じる際には、軽い力で矢示方向に押圧すれば、段部２７（内面側の端縁１ｈ）と缶口部側壁上縁とのに当接を解除できる。
【００３３】
また、この実施例では、頂板２８の下面２８ｂで、開閉蓋部１ｂの自由端側（摘み片７付近）の突片１０Ａの両側の間隙に、夫々案内突片３１を突設する。前記案内突片３１は、前記自由端の側の突片１０Ａと略直角になるような弦上に配置され、案内突片３１の先端縁３１ａは、突片１０Ａと略同一位置に配置されている（図１０（ａ））。
【００３４】
案内突片３１は、突片１０と略直角としたが、頂板２８のほぼ内側（中心側）を向いて配置されれば他の角度でも可能である。
【００３５】
突片１０Ａが外側（摘み片７側）に屈曲した場合、開閉蓋部１ｂを缶２３の缶口部４に被せた場合、開閉蓋部１ｂを缶口部４に嵌装できないおそれがある。この際、案内突片３１の先端縁３１ａが缶口部４の案内となって、缶口部４に開閉蓋部１ｂを嵌装させることができる。
【００３６】
また、頂板２８の下面２８ｂで、固定蓋部１ａの自由端側の突片１０Ｂの両側の間隙にも同様に、夫々案内突片３１を突設する。前記案内突片３１は、前記自由端の側の突片１０Ｂと略直角になるような弦上に配置され、案内突片３１の先端縁３１ａは、突片１０Ｂと略同一位置に配置され、開閉蓋部１ｂの案内突片３１と同一弦上に位置する（図１０（ａ））。この案内突片３１も、開閉蓋部１ｂの案内突片３１と同様に作用する。また、固定蓋部１ａの突片１０は、開閉蓋部１ｂの突片１０より幅広（約２倍）に形成されているので、缶口部４とより強く掛止できる。
【００３７】
また、この実施例では、摘み片７の肉厚を他の部分より外側に向けて厚く（約２倍）形成してある。従って、開閉蓋部１ｂを引き起こす際に、摘み片７の下縁７ａを指で掛止するので、開閉し易くなる（図１０（ａ）、図１１）。
【００３８】
また、この実施例では、帽状蓋１は、全体を透光性を有する（透明、半透明）材質で形成し、帽状蓋１の頂板２８の上面２８ａにフィルム３０を頂板２８と一体に貼付してある（図１２（ａ））。前記フィルム３０は、頂板２８との接着面（下面２８ｂ）に樹脂との親和性のあるコーティングを施して成型用の金型内に配置され、樹脂の成型時に樹脂と一体に貼付される（図１２（ｂ））（インプラント加工）。
【００３９】
また、この場合、フィルム３０の裏面３０ｂに、缶２３の「内容物の取扱い説明」などを記載すれば、開閉蓋部１ｂを引き起こした際に、開閉蓋部１ｂの裏面側からフィルム３０の裏面３０ｂの「内容物の取扱い説明」が目視できる。例えば、粉ミルク用の缶用の帽状蓋１とした場合には、「『月齢』に応じた『１回の粉ミルクの使用量』『１日の授乳回数』その他の注意書き（標準使用量表）」を、フィルム３０の表裏面３０ａ、３０ｂに夫々記載しておけば、開閉蓋部１ｂの引き起こし前後で使用量を確認できるので、便利である。
【００４０】
【発明の効果】
この発明の摺り切り片付き蓋によれば、従来必須要件としていた外蓋が不要となり、しかも封緘も確実で、開缶後も蓋をそのまま使用し得るなどの効果がある。
【００４１】
この発明の蓋付き缶によれば、開缶後蓋を取り外す必要がなく、必要な部分のみ開蓋し、内容物を摺り切り使用し得る効果がある。従来は摺り切り片付き仕切り板などで、他に外蓋又は換え蓋が必要であり、しかも外蓋は取り外しを必要としていたので、外蓋の置き場所が必要であり、外蓋の置き場所が適切でないと汚染の恐れがあるなどの問題点があったが、この発明によれば、缶口部に嵌装したまま使用できるので、前記問題点はないなどの効果もある。

[0028]
If the contents are taken out as described above, the opening / closing lid portion can be tilted and fitted into the can mouth portion to maintain airtightness, so that a separate outer lid is unnecessary. Therefore, according to the above embodiment, it is possible to provide a can that is completely sealed, does not require an outer lid, has a simple structure, and can securely hold contents.
[0029]
[Example 3]
Another embodiment of the present invention will be described with reference to FIGS.
[0030]
As in the first embodiment, the cap-shaped lid 1 is divided into a fixed lid portion 1a and an open / close lid portion 1b on the side wall of a synthetic resin cap-shaped lid 1 that can be fitted into the cylindrical can mouth portion 4. The fixed lid portion 1a is formed by a circular arc portion 1c fitted to the can mouth portion 4 and a linear connecting portion 1d connected to the opening / closing lid portion 1b. On the lower surface of the fixed lid portion 1a, a sliding piece 3 is provided so as to protrude downward in the vicinity of and parallel to the connecting portion 1d. The opening / closing lid portion 1b is formed by an arc portion 1e fitted to the can mouth portion 4 and a linear connecting portion 1d connected to the fixed lid portion 1a, and is fitted to the fitting portion of the arc portion 1e. Is provided with a cutout part 5 for opening and a knob 5a, and the cutout part 5 is provided with a cutout 6a for cutting out from the side wall and thin parts 6b and 5b. After the cutting, incisions 8 and 8 are provided at predetermined intervals in order to form the knob 7. Further, on the inner side of the lower edge of the side wall of the cap-shaped lid 1, there is provided a fitting portion 9 for fitting on the annular convex portion 4 a of the outer wall of the can mouth portion 4, and the top plate of the cap-shaped lid 1. A plurality of protruding pieces 10, 10 that hang on the upper end curled portion 4 b of the can mouth portion 4, close to the outer peripheral edge, are arranged at predetermined intervals at positions along the inner surface of the can mouth portion 4. The protrusions 10 and 10 are provided with latching protrusions 10a and 10a (FIGS. 1 and 2).
[0031]
In this embodiment, the size of the fixed lid portion 1a is less than half that of the cap-like lid 1, and the straight edge (slid piece 3) has a string shape. Similarly to the first embodiment, when the opening / closing lid portion 1b is raised, the base portion (sliding piece 3 side) 1f of the side wall of the opening / closing lid portion 1b is formed so as to ride on the side wall of the can mouth portion. (FIGS. 9A and 2), the base 1f is thinned so that the inner surface is concave, and a stepped portion 27 is formed on the inner surface. Accordingly, the outer edge 1g of the base 1f is formed so as to protrude from the inner edge 1h toward the fixed lid 1a, and the inner edge 1h is a step 27 (FIG. 9). (B) (c)).
[0032]
In this case, when the base portion 1f of the side wall of the opening / closing lid portion 1b is pulled up so as to ride on the can mouth portion side wall, the step portion 27 (the edge 1h on the inner surface side) contacts the upper edge of the can mouth portion side wall. In contact therewith, similarly to the first embodiment, the return of the opening / closing lid 1b can be prevented. At this time, the edge 1g on the outer surface side of the base portion 1f is on the outer surface side of the side wall of the can mouth, thereby preventing the base portion 1f from entering the can mouth. Therefore, when closing the opening / closing lid portion 1b, the contact between the step portion 27 (the inner edge 1h) and the upper edge of the can mouth portion side wall can be released by pressing in the direction indicated by the arrow with a light force.
[0033]
Further, in this embodiment, the guide protrusions 31 are respectively provided in the gaps on both sides of the protrusion 10A on the free end side (near the knob piece 7) of the opening / closing lid 1b on the lower surface 28b of the top plate 28. The guide protruding piece 31 is arranged on a string that is substantially perpendicular to the protruding piece 10A on the free end side, and the leading edge 31a of the guiding protruding piece 31 is arranged at substantially the same position as the protruding piece 10A. (FIG. 10A).
[0034]
The guide protrusion 31 is substantially perpendicular to the protrusion 10, but other angles are possible as long as the guide protrusion 31 is disposed so as to face substantially the inner side (center side) of the top plate 28.
[0035]
When the protruding piece 10A is bent outward (to the knob piece 7 side), when the opening / closing lid portion 1b is placed on the can mouth portion 4 of the can 23, the opening / closing lid portion 1b may not be fitted into the can mouth portion 4. At this time, the leading edge 31 a of the guide protrusion 31 serves as a guide for the can mouth portion 4, and the opening / closing lid portion 1 b can be fitted to the can mouth portion 4.
[0036]
Similarly, guide protrusions 31 are provided on the lower surface 28b of the top plate 28 in the gaps on both sides of the protrusion 10B on the free end side of the fixed lid portion 1a. The guide protrusion 31 is disposed on a string that is substantially perpendicular to the protrusion 10B on the free end side, and the leading edge 31a of the guide protrusion 31 is disposed at substantially the same position as the protrusion 10B. It is located on the same string as the guide protrusion 31 of the opening / closing lid 1b (FIG. 10A). This guide protrusion 31 also acts in the same manner as the guide protrusion 31 of the opening / closing lid 1b. Further, since the protruding piece 10 of the fixed lid portion 1a is formed wider (about twice) than the protruding piece 10 of the opening / closing lid portion 1b, it can be hooked more strongly with the can mouth portion 4.
[0037]
Further, in this embodiment, the thickness of the knob 7 is formed thicker (about twice) outward from the other portions. Therefore, when the opening / closing lid 1b is caused, the lower edge 7a of the knob 7 is hooked with a finger, so that the opening / closing lid 1b is easily opened and closed (FIGS. 10A and 11).
[0038]
In this embodiment, the cap lid 1 is entirely formed of a light-transmitting material (transparent and translucent), and the film 30 is integrated with the top plate 28 on the upper surface 28 a of the top plate 28 of the cap lid 1. Affixed (FIG. 12A). The film 30 is placed in a molding die with a coating having affinity for resin on the adhesive surface (lower surface 28b) to the top plate 28, and is attached to the resin integrally when molding the resin (FIG. 12 (b)) (implant processing).
[0039]
In this case, if the description of handling of the contents of the can 23 is described on the back surface 30b of the film 30, when the open / close lid portion 1b is raised, the back surface of the film 30 is opened from the back surface side of the open / close lid portion 1b. 30b "Description of handling of contents" is visible. For example, in the case of a cap 1 for a can for powdered milk, ““ Amount of powdered milk used at one time ”“ Number of breastfeeds per day ”and other cautionary notes (standard usage table) ”” On the front and back surfaces 30a and 30b of the film 30, respectively, it is convenient because the amount used can be confirmed before and after the opening and closing lid 1b is raised.
[0040]
