Description

Technical Field

[0001] The utility model relates to the technical field of straws, in particular to a cut-off straw. Background Art

[0002] The straw works on the principle of atmospheric pressure. When in use, some air will be sucked away through the straw, which will cause the pressure inside the tube to decrease. In order to balance the air pressure, the atmospheric pressure will force the liquid in the tube to rise. When you stop inhaling, the liquid in the tube will drop and the pressure will return to balance.

[0003] Chinese patent number CN104095479A discloses an automatically closing straw structure, including a straw body, on which an indentation is arranged, the straw body forms a natural bend along the indentation, the indentation seals and blocks the passage of the straw, and when the straw tends to be straight, the interior of the straw is connected, and the indentation is arranged at the golden section point of the length of the straw.

[0004] If the existing technology wants to achieve the cut-off straw, it is necessary to set an automatically closing structure on each straw. However, in real life, most straws are disposable straws, and straws are in great demand in daily life. If an automatically closing structure is set on each straw, the cost is too high and it is not suitable for mass production. Utility Model Content
