PROBLEM TO BE SOLVED: To prevent a foreign matter from being mixed when a film is separated without separably applying the film to the inside face of a can lid as a means for preventing a powder/grain body contained from jetting out and scattering in opening a can as to a fully-opened and easily-opened can container for a positive pressure can containing granular matter. SOLUTION: A small hole 40 which jets out a gas but not a powder/grain body by the inner pressure of a can is formed in a thin sheet material 4 made of an airtight material. A small hole 30 whose area is larger than that of the hole 40 of the sheet material 4 is formed in a panel part 21 of a can lid. The sheet material 4 is integrally applied to the panel part 21 of the can lid so that the hole 40 is positioned in the range of the hole 30. A film lid 5 with a handle part 5a is separably applied to the panel part 21 of the can lid sealing and covering the hole 40 from the outside face of the can lid. COPYRIGHT: (C)2009,JPO&INPIT
