Visualization and Comprehension of Opening Instructions in Child Resistant Packaging

Abstract

Child-Resistant Packagings (CRPs) have emerged as a solution to prevent poisoning accidents involving children, however these packagings end up becoming an obstacle in the opening process, for youth, adults and especially the elderly. In this type of packaging is common for the opening instructions be arranged on top of the cap, but there is no pattern for how this information is presented. The aim of this study was to evaluate the visualization and comprehension of opening instructions in squeeze-and-turn CRPs. The study had the participation of 10 adult subjects and 12 elderly subjects, which were equally divided between men and women. Three different packaging of mouthwashes were used. Data was tabulated in electronic spreadsheets. The results show that the packaging with the largest diameter and the most simple and objective image showed the best visualization and comprehension levels.
