Description
また、第1発明に係る紙蓋によれば、内嵌合部の内面側には、天板部の縁からしわがない範囲を有するので、紙蓋と容器とを隙間なく嵌合させることができ、内容物の漏れを抑制できる。
また、第1発明に係る紙蓋によれば、頂部にしわがあるので、外嵌合部を成型する際に、ブランクを第4方向へ引っ張っても、頂部でブランクが破れることなく、紙蓋を成型することができる。
さらに、第1発明に係る紙蓋によれば、フランジ部の先端にしわがあるので、紙蓋の端面で手や指が切れてしまうことを抑制できる。
図1(a)は、この発明の一実施形態に係る紙蓋の一例を示す模式平面図、図1(b)は、図1(a)中のIB−IB線に沿う模式断面図である。図2は、図1(a)中の破線枠II内を拡大して示す模式断面図である。

図7は、この発明の一実施形態に係る紙蓋の製造に使用可能な加工機の一例を示す模式断面図である。
<傾斜部形状>
図14は、この発明の一実施形態に係る紙蓋の一例を示す模式断面図である。図14に示す断面は、例えば、図2に示した断面に相当する。
図16(a)は、この発明の一実施形態に係る紙蓋の一例を示す模式断面図である。図16(b)は、この発明の一実施形態に係る紙蓋の一例に嵌合可能な紙容器を示す模式断面図である。
Poor: 漏れ出る
Good: 環状凹部16内に僅かな滲みが認められるが、漏れ出ることはない
Excellent: 漏れ及び滲みのいずれもなし
紙蓋1は、状態“Good”又は状態“Excellent”となると、紙容器2が倒れても内容物
の漏れを抑制でき、紙蓋1が、より実用的なものとなる。
テーパー角θが約4°15´のとき、割合Pが約23.8%で状態“Good”となった(“i”参照)。
テーパー角θが約5°のとき、割合Pが約17.1%で状態“Good”となった(“ii”参照)。
テーパー角θが約6°15´のとき、割合Pが約13.1%で状態“Good”となった(“iii”参照)。
テーパー角θが約7°30´のとき、割合Pが約7.7%で状態“Good”となった(“iv”参照)。
また、漏れ試験からは、テーパー角θが0°に近づくにつれ、状態“Poor”から状態“Good”にできる割合Pが高まる傾向が確認された。紙蓋1と紙容器2との組み合わせを最適化するには、例えば、以下のようにするとよい。
P=−4θ+36 …(1)
から導かれる値以上の値が選ばれる。
紙容器2の口外径D22は、外嵌合部14の外径Dよりも大きくてもよい。この場合、フランジ部15の外径D15は、口外径D22よりも大きいことが好ましい。
