| Abstract |
| Since 2010, 729 persons were injured when they opened full aperture type metallic can for 3 years. To respond such problem, some companies developed a new opening method with a kind of easy open end, but it has not been employed widely. Thus, the difficulties in opening continue to the silver generation with a new purchasing power. The aim of this study is to analyze problems in the opening in order to improve easiness and safety in the opening and to create guideline for product design dedicated to the silver generation.
To achieve such aims, basic survey through questionnaire survey and in-depth survey through the opening process were carried out. The basic survey was on the hypothesis that the silver generation was different from the other generations. And sampling by generations was made to examine the easiness and safety of the can opening. Then, the in-depth analysis was carried out to specify problems by action factor in the opening process, and then a guideline was raised as below.
First of all, the usability was examined from the easiness of opening. As a result, the below guideline was suggested.
First, the opening is processed with embossing to figure out the front/rear of tap in the initial stage of opening.
Second, proper setting of distance is to be made between tap and surface of can so that it can be operated as a lever.
Third, as tensile strength of finger holding tap, grip strength holding body of product, and tensile strength of hand and arm to open the cap are much required, it is recommended to use aluminum foil instead of steel which shall be extended to the whole products without limitation.
And for the safety analysis, examination on spilling or dropping was carried out. As a result, the below guideline was suggested.
First, by proper controlling the gap between tap and surface of can, the embossing design of the can cap so that a finger can be inserted to the bottom of tap is needed.
Second, it is recommended to use aluminum foil instead of steel which shall be extended to the whole products without limitation.
Third, it is recommended to reduce the cutting side exposure by making different internal height between the external vertical height and the internal height where can cap is attached.
This study is significant in that it suggested improvement measurements for usability and safety in the use of full aperture type metallic can by means of case study and in-depth study through questionnaire survey. However, this study has a limit as it did not extensively cover children and the disabled. Accordingly, further studies is expected in those areas. |
