Smile drink / drink bottle

Smile drink
Smile drink

In the common way of drinking, the liqiud is likely to be
polluted by our mouths which effects the quality of the liqiud
and shortens its shelf-life, expecilly when someone in the
family is ill. Using smile drink you don not have to pour the
liquid and can determine how much you drink. Press more,
drink more. The rest of the liquid remains undamaged.
The cup rim is curved designed. You press the rims marked
by blue, and drink at the rims marked by green, also the
green rims touch the table when the bottle is upside down.
Therefore, don not worry the rims you drink at is unclean.
