Locked4Kids consists of a carton and a plastic tray that holds the product, e.g. medicines in blister strips. To access the product, the tray should be pulled out like a drawer. To secure child safety this only works if two hooks on the top of the carton are pressed simultaneously. Looking closely at the Locked4Kids carton, you will find two push points with hooks sticking out. These push points are located diagonally across each side of the carton.
And that’s why children have difficulties opening the cartons. They simply don’t understand how it works. And if they do, they are not able to handle it physically because their hands are too small.
According to US regulations only immediate or primary packagings qualifies as child resistant packaging. Besides this, these packagings have to pass testing according to protocol F=1 US16 CFR 1700.20. To qualify as primary packaging, all packaging parts should stay connected after each opening by the consumer. Locked4Kids meets these requirements; all packaging components stay firmly connected, each time the packaging is opened and re-closed by the user.
