Background technique

A variety of cupped drinks have gradually become indispensable things in people's daily life. A cup of hot drink can bring a touch of warmth to people in cold weather. As a convenient suction tool, straws are widely used in the field of beverages. Scientific research shows that the best drinking temperature for the human body is when the temperature of drinks is between 40°C and 50°C. Overheated drinks will damage the oral mucosa and even burn the esophagus, especially for children with more sensitive mouths, which may cause more serious consequences. ; And the temperature of the drink that is too low may cause discomfort to the body and stomach, and even cause gastrointestinal diseases. In daily life, people, especially infants and young children, often cannot correctly judge the temperature of the drink in the cup when they use a straw to suck the drink, so that the mouth is scalded by the overheated drink.

At present, most of the straws on the market are plastic straight-through straws, and the single function and structure can no longer meet people's increasing living needs.
