PROBLEM TO BE SOLVED: To provide an exhalation storage bag having a small ventilation hole for efficiently monitoring the sense of smell by two or more people's sense of smell as to an exhalation storage bag necessary for monitoring bad breath. SOLUTION: An existing polyethylene bag whose opening is provided with a chuck (a fitting function) is used for producing inexpensively. An adhesive closing part 4 is provided on the opening of the polyethylene bag for dividing the bag into two parts comprising a small opening 3 (an opening for blowing in exhalation) and a large opening 2 (an opening for introducing a gas containing the scent of a flower, etc.). An adhesive line 5 forms a tip narrowing small ventilation channel 6 from the adhesive closing part to the side edge of the bag. The width of the channel at the tip end of the line is small enough for fingers to hold and stop ventilation. COPYRIGHT: (C)2004,JPO&NCIPI
