Objective: To compare and examine several prototype OTC packages with the function of CRSF.  Materials and Methods: Practical trial test both the elderly and the children had been done with 3 prototype packages. As for the children (42~51M), they opened 3 type (A, B, C) packages, and the status of opening packages was evaluated. As for the elderly(65-81,mean74.2), they tried same 3 type packages, and hearing usability and all over evaluation of packages. The status of opening packages was scored with NRS (Numeric Rating Scale). Usability are also scored. And, free comments are collected. Results: The test of children, A: nobody could open in right way and 4 opened incorrect ways. B; 7 ones could open in right way and 4 opened incorrect ways. C: 3 ones opened in right way and 4 opened incorrect ways.
