Why your participation matters
Everyday packaging should keep children safe without making life harder for adults.
Yet millions of people living with arthritis, reduced hand strength, disability, or age-related changes struggle daily with packaging that was never designed with them in mind. This often leads to frustration, loss of independence, unsafe workarounds, or missed medication.
At this stage, our in-person testing can only take place with volunteers who are based in, or able to travel to, the Didcot, London, or Oxfordshire areas. This allows us to run sessions safely, consistently, and in line with our current resources and ethical approvals.
At Elddir, we’re working to change that.
We believe the only way to solve this problem properly is by working with the people most affected by it. By taking part in testing, you’re not just helping us improve a product, you’re helping demonstrate that this is a real, important, and long-overlooked issue that deserves better solutions.
Your experience helps ensure that future packaging is designed around real lives, not assumptions.
What taking part involves
Adult usability testing
For adults, particularly those living with arthritis, reduced hand strength, or dexterity challenges participation may involve:
- Attempting to open and reclose child-resistant packaging
- Using packaging in realistic, everyday scenarios
- Short, task-based sessions focused on ease of use, comfort, and confidence
- Optional discussion or feedback on what felt intuitive or difficult
Sessions are typically 30–40 minutes and are designed to be respectful, comfortable, and non-strenuous.
Child safety testing
Where appropriate approval has been granted, we also conduct child safety validation with:
- Children aged 42–51 months, in line with recognised British and international child-resistance standards
- Carefully structured, supervised tasks that assess whether packaging can be opened
- Testing carried out in safe, familiar environments, following established protocols
These sessions are designed to assess child resistance only, and always prioritise safety and wellbeing.
