The proposed re-usuable toothpaste cap can be capped onto new toothpaste refill tubes when the old toothpaste tube is finished. An inverted conicle detail within the cap breaks the hygiene seal on the refill tube with ease when the re-usable cap is screwed on. The product lifetime of the plastic cap is prolonged while the number of caps thrown away is reduced greatly.
The toothpaste is a daily necessity that we often neglect because of its small size. 12 toothpaste caps per household can amount up to 200 million caps in Germany per year! Every bit counts, so let us start from our homes -- no more waste toothpaste caps!
