<P>PROBLEM TO BE SOLVED: To provide a sealed container and a cap which do not necessitate the use of another can for storing ground coffee beans, etc., whose bag is simply produced, whose check valve is not easily seen even when the bag is clear, and the bag surface design of which is not restricted because of the check valve. <P>SOLUTION: This relates to a sealed bag 3 having a mouth 2 with a cap 1 for taking out or filling a content. The cap 1 has a vent hole 5 and a check valve 6 on the inside of the cap 1 for preventing air from coming in from the outside through the hole 5. The vent hole 5 is formed on the top 1c of the cap 1, and the valve 6 with a roughly disk shaped outer appearance is connected to the top 1c. The top 1c is protrusively provided with a catching part 7 for catching the peripheral edge of the valve 6. The catching part 7 is pressed down by the edge 2c of the mouth 2 in the catching direction toward the peripheral edge of the valve 6 when the cap 1 is closed on the mouth 2. <P>COPYRIGHT: (C)2004,JPO |
