Which tricks are used?

There are several options:

  • Children at the defined age of 42 to 51 months have great difficulties in performing two movements simultaneously, for instance squeezing a closure while turning it (in the right direction, mind you).
  • Spacing out the unlocking parts so far apart that children cannot reach them with the fingers of one hand.
  • Plastic film or foil packaging, e.g. refill bags or blisterpacks, must have hidden opening points or must be designed in a way that a tool is required for opening.
