Abstract
Description
蓋は、コップ状の飲用容器に被せられる蓋であり、ホット飲料入りの容器の蓋として用いてもよいし、コールド飲料入りの容器の蓋として用いてもよい。
引張破断伸度(%)={(L−L0)/L0}×100
L=破断時の試料の長さ
L0=試験前の試料の長さ
また、蓋は、リサイクル材を含んでいてもよい。
蓋は、通常、円板状の天板部と、天板部の外周縁と連続する円筒部とから構成される。円筒部の一端は天板部と連続し、他端は、円形の開口端を形成する。蓋は、例えば以下のサイズを有する。開口端の内径は、例えば60〜100mmであり、天板部の径は、例えば60〜100mmであり、円筒部の高さは、例えば5〜50mmである。
次に、蓋12の製造方法について図4を用いて説明する。
先ず、生分解性樹脂からなるロールシートを、送出装置により搬送路に沿って送出する(ステップST1)。次に、搬送されたシートを、圧空成形装置のヒータによって加熱する(ステップST2)。
樹脂材料として、ポリブチレンサクシネート(PBS)とポリ乳酸(PLA)との比率(質量比)を以下のとおり変化させた樹脂混合物を用いて、図1〜3に示す蓋を製造した。
例1 PBS:PLA=100:0
例2 PBS:PLA=90:10
例3 PBS:PLA=70:30
例4 PBS:PLA=0:100
「熱に対する形状安定性」、「着脱操作に対する形状安定性」、および「ヒンジ適正」について評価した。容器本体は、紙基材から形成される容器本体(日本デキシー製GDNC09AR)を用いた。
評価結果を表1に示す。
