PROBLEM TO BE SOLVED: To stop the dissolution of the component of tea when a water amount is decreased and to prevent over-dissolution by means of permitting a filter paper bag to stay in the upper part of a pitcher by providing a tongue shape part in the upper part of the filter paper bag and a part for storing tea leaves in the lower part. SOLUTION: The tea bag is constituted of bag shape filter paper, provided with the tongue shape part 2 and sealed in the filter bag after putting the tea leaves in a tea leaves storing part at a lower part. When the tea bag is used, water is poured into the pitcher, the tongue shape part 2 of the filter paper bag 1 is hooked at the upper part of the pitcher and a lid is closed to hold it. When the pitcher is full of water, the filter paper bag 1 is soaked in water so that the component of the tea leaves is dissolved. When the water level of the pitcher is lowered after pouring a several cups of tea in the pitcher, the bag 1 stays in the upper part of the pitcher and is not soaked in water so that the dissolution of the component of the tea leaves is stopped. Then, over-dissolution problem in a conventional manner is solved and also the tea bag is easily taken-out. |
