Drinking bottle with breathable structure

Abstract

The invention discloses a drinking bottle with a ventilation structure, and belongs to the field of bottles. The drinking bottle comprises a bottle body and a bottle cover, wherein the bottle cover comprises an air inlet for air intake and a drinking suction nozzle for sucking beverages; the ventilation structure is arranged inside a cavity of the bottle body; the ventilation structure comprises a soft silica gel tube and a hollow floating ball; one end of the soft silica gel tube communicates with and is connected to the air inlet, and the other end of the soft silica gel tube communicates with and is connected to the hollow floating ball; more than one air outlet, which communicates with the air inlet, are arranged at the top of the hollow floating ball; and a vent check valve is arranged on each air outlet. By virtue of the ventilation structure which is added inside the bottle body, air inside the bottle body basically communicates with external atmosphere, so that the beverages can be drunk more easily and babies can feel easier to suck the beverages; compared with a conventional structure which is arranged on a bottle cover and simultaneously serves as a valve body, the drinking bottle has lower requirement on production technology and lower manufacturing cost; and by arranging the vent check valve inside the bottle body, any phenomenon that liquid inside the bottle body flows back is avoided.

Description

technical field [0001] The invention relates to the field of bottles for containing beverages, in particular to a drinking bottle with a ventilating structure. Background technique [0002] Traditional feeding bottles, sippy cups, learning cups, etc. are all composed of a bottle body and a bottle cap, and an air inlet and a drinking nozzle are provided on the bottle cap, and the drink in the bottle body is sucked through the drinking nozzle. In the traditional structure, the air inlet is set as a one-way valve structure, and the outside air can enter the bottle body from the bottle cap in one direction. [0003] When in use, when the beverage in the bottle body is sucked through the drinking nozzle, the beverage in the bottle body will be sucked away, the air in the bottle body will become thinner and the pressure will decrease. In the bottle body, the drink in the bottle body can be continuously absorbed. [0004] In the traditional structure, the one-way valve is set on ...

AI Technical Summary

Problems solved by technology

Therefore, in this process, a greater negative pressure is needed so that the outside air can enter the bottle body, and due to the lack of negative pressure, the process of drinking water will always be very unsmooth, or it will not be easy to absorb the milk in the bottle, thus Affect the baby's normal milk intake

[0005] In addition, the traditional one-way valve is set on the bottle cap. In the existing technology, it is difficult to double the valve body structure on the pacifier. The technical content of processing the valve body is relatively high, which will not only increase the difficulty of product production, but also improperly set or Improper installation will cause water leakage or airtightness, which will affect subsequent normal use
