Bottles used for storing carbonated water and soft drinks, has an uneven bottom for stability reasons. The technology was developed and patented by Lithuanian Domas Adomaitis in 1971. The indentations can be viewed as a “petaloid”, because it is shaped like a flower with petals.


Preforms (uninflated bottles) are now also used as robust and unique containers themselves; besides novelty candy, some Red Cross chapters distribute them as part of the Vial of Life program to homeowners to store medical history for emergency responders.
