A sealing mechanism for a container opening comprises a cylindrical opening (1) for a container body (11), and a cap (5) for sealing the cylindrical opening. The cap has a cylindrically shaped cap body (12) for surrounding a side surface (1a) of the cylindrical opening, and is provided with a threaded portion (20) disposed on an inner cylindrical surface thereof for engaging with a correspondingly threaded portion (6) disposed on an outer surface of the cylindrical opening. The cap body is capable of moving up and down whilst rotating around the cylindrical opening. The cap also has an upper lid (13) for covering an opened upper end (1c) of the cylindrical opening and for sealing the cylindrical opening. The cap body and the upper lid are independent of each other so that the cap body can be rotated without rotating the upper lid. When the cap body is rotated around the cylindrical opening to move towards the upper end of the cylindrical opening, the cap body abuts the upper lid, and pushes the upper lid away from the opened upper end (1c) to open the cylindrical opening.

A packaging bag comprises a bag body (1), the first heat sealed portion (5), and the second heat sealed portion (5) and a tear-starting portion. The bag body is made of a plastic laminate film having a pair of opposite side edges (2, 3). The bag body is formed by bringing the pair of opposite side edges into contact with each other and heat-sealing them (4) over their entirety to form a tubular shaped body having a rear heat sealed (4) portion, and collapsing the tubular shaped body into a flatten shaped body having a front face, a rear face opposing the front face, a pair of opposite side edge (2, 3) portions connecting the front face and the rear face to each other, a first opened portion and a second opened portion opposing the first opened portion. The rear heat sealed portion is placed on the rear face. The first heat sealed portion is formed by heat-sealing the first opened portion (5). The second heat sealed portion is formed by heat-sealing the second opened portion (6). The tear-starting portion is provided on at least one of the pair of opposite side edge portions and the rear heat sealed portion. The tear-starting portion (7) comprises fine concavities opening outwardly.
