Dispensing
Child-resistant packaging, and the two numbers it has to hit
Updated
A package under the Poison Prevention Packaging Act has to defeat a four-year-old and must not defeat a seventy-year-old, and both are measured on panels of real people. Everything about these containers follows from that tension.
The standard
Two numbers, two panels, one package.
The package
Why a closure on its own is not enough.
What goes wrong
Named failures, with the cause for each.
Containers
What the bottle has to do besides resist a child.
