Abstract: An article represented by a container that is formed of a thermoplastic resin blended with a metal or a metal compound that can react with a corrosive gas or a volatile sulfur compound and give a color. The thermoplastic resin includes at least one metal selected from three metals of Zn, Sn and Mn or one metal compound thereof, and a metal or a metal compound that is not any of these three metals and that can react with the corrosive gas or the volatile sulfur compound and give a color. The metal selected from the three metals or the metal compound functions as a scavenger for the corrosive gas or the volatile sulfur compound.

Abstract: To provide a filling device that realizes simplification of device configuration, improvement of design freedom, and redaction of production loads, and that prevents formation of a pointed peak on the upper surface of packed contents, or uneven filling of the container. Provided is a filling device (10) including a filling nozzle (20), a contents supplier (30), a plunger (40), and a gas supplier (50). A gas inlet (25) connected to the gas supplier (50), a gas outlet (26) opened to the nozzle hole (23), and a gas flow passage (27) are formed in the filling nozzle (20). The gas (A) supplied from the gas supplier (50) is ejected from a gap between an inner circumferential surface of the nozzle hole (23) and an outer circumferential surface of the plunger (40) at a lower end of the filling nozzle (20).
