  • Patent number: 10932991
    Abstract: The present application relates to the technical field of baby appliance structure, and provides a feeding bottle, including: a body and at least one non-return valve integrally formed at a lower of the body. The non-return valve includes a connection portion that is connected at the body, an extension portion for disturbing the laminar flow state of the internal liquid of the body when shaking the body, and a valve for allowing only the air outside to enter into the body, the extension portion is tapered and extends along a surface of the body toward the interior of the body, the extension portion is located at the inside of the bottom of the body, or located above the inside of the bottom of the body and in the vicinity of the inside of the bottom of the body. This design can solve the problem that the structure of the existing feeding bottle may cause flatulence to the baby due to the unbalanced pressure and may easily lead to incomplete dissolution of the milk powder.
