Thumbcap / a bottle cap


‘Thumbcap’ is a simple designed cap which can open the bottle with a thumb.
We usually need two hands to open a bottle cap. Sometimes we can be in a dead-end situation that we can’t use two hands but only one hand in our daily life. This product is aimed for the people who are in such as the uncomfortable condition to open the bottle with only one hand easily. No need two hands. Just only one thumb is enough for opening a bottle. A projection of the cap assists a person in opening the bottle with one thumb.
‘Thumbcap’ is not a disposable product. When you reuse this, you can use it again in many kinds of bottles instead of throwing it away.
