I created this clip for the IKEA Sortera bin to stop our 14 months old little toddler from opening and throwing everything inside out on the floor.

Just snap the clip onto the lid from the bottom en gently force it over the edge on the top. When you close the lid it automatically prevents the lid from being easily opened.

To open the lid just pull/bend the lid close to the clip/clips towards you and it opens easily. You can also slide the clips to the center of the lid to unlock it.
