Protective medical storage
I was inspired by my grandparents own difficulties with opening present child safe products and found that they were a common issue among the differently abled. On top of this I found that the present child resistant caps do not necessarily stop children, and that there are as many as one child a day admitted for accidental poisoning in Bristol Hospital alone each year.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
The Coloursafe CRC has been designed to replace the existing design of child resistant caps presently used in medical and domestic bottles which do not adequately keep children out. The colour safe cap has been shown to keep children out while allowing access to those suffering from arthritis and other degenerative conditions such as loss of sight.
OPERATION / FLOW / INTERACTION:
The cap has three wheels acting as a combination lock, each with a thick embossed line corresponding to points at the top and base of the cap. Once aligned the cap slides free with little effort. This design is an improvement on existing child resistant caps which depend on a degree of material deformation, not suitable for those users with arthritis or other degenerative diseases. Each wheel is marked with portions of shapes distracting children who may attempt to open the bottle. Each shape once completed do not allow the cap to open, and the limited options make children bored quickly making them lose interest in the bottle.
PROJECT DURATION AND LOCATION:
The project started in March 2012 and ended in June 2012 in Cardiff South Wales The Products was tested in Cardiff and Ammanford South Wales.
PRODUCTION / REALIZATION TECHNOLOGY:
This product is made using three designed parts (x3 turning wheels making five parts in the cap) and a bottle with specialised locking teeth. Each part of the cap has a 0.75 degree draft angle to allow each to be made for two part injection molding. The bottle, including the toothed neck is suitable for blow molding processes. Due to the processes selected, a variety of materials could be used for the final product depending on the substance being stored e.g. medical or corrosive substances.

Desk based research
-Issues with existing child resistant caps.
-Review of the effectiveness of existing caps
-The main ages of risk for children.
-Child psychology and development.
The difference in development between children and adults became the key to designing the cap rather than force. The designs were tested with children aged 3-7 years and adults with arthritis and/or sight loss aged 45-100 years. The cap proved effective every time at keeping children out, and at allowing adults to access the contents.
The hardest part of this design was to keep children out and allowing those with limited abilities in, requiring a new approach to the child resistant cap. Using the concept of mental development it was clear to design a system that would stop children using a simple and easily exhaustible colour and shape puzzle, while providing an adult with a more practical embossed rib to align. The age range of children at risk is 2-7 years. At these ages a child will not make the connection to use the embossed line as a guide for unlocking the cap.
