<p>PURPOSE: To ease opening of a closure cap that sterilizably and hermetically seals a bottle closed with rubber elastic sealing element by connecting the lid region of a capsule and plastic lid radially outside a tear line, and making a groove axial with respect to the tear line on the lid. CONSTITUTION: This closure cap disposed on the neck 2.1 of a bottle 2 suitable for blood transfusion or the like is equipped with a flanged capsule 3 made mainly of thin aluminum plate, which has been fixed to the bottle neck 2.1 in the range of the edge region 4 formed with a constricted part. The lid region 3.1 of the capsule 3 has a central hollow 3.3, to which the center of a plastic lid 5 has been fitted. Besides, the lid 5 has a guiding fold line 8 that extends on the diameter, and the lid region 3.1 and lid 5 are connected radially outside the tear line 14 at the adhesion spot 9.2. And a groove 13 is formed so as to cross practically normal to imaginary line 10 connecting two adhesion spots 9.1, 9.2, and the tear line 14 is provided in the range of this groove 13.</p> |
