Preferably, the stepped portion has an inclined surface, and the first annular portion has a vertical wall surface, and an included angle between the vertical wall surface and the inclined surface is greater than 90 ° and less than 140 °.
Preferably, the sealing ring is provided with an extension part, and the extension part is positioned on the side surface of the first annular part and abuts against the step part.
Preferably, the second annular part is provided with an annular barrier strip, and the annular barrier strip is positioned below the external thread.
Preferably, the outer surface of the bottle cap is provided with anti-skid grooves, and the anti-skid grooves are arranged at intervals.
Preferably, the anti-slip groove extends from the top to the side of the bottle cap.
The technical effects of the utility model: the sealing structure of the feeding bottle of the utility model can further enhance the sealing performance of the feeding bottle and avoid the milk leakage in the feeding bottle; in addition, the milk remained on the bottle mouth can be prevented from flowing onto the bottle body along the bottle mouth after drinking.

Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
As shown in fig. 1 to 4, the sealing structure of the feeding bottle of the present embodiment, the feeding bottle 1 includes a bottle cap 2 and a bottle mouth 3, the bottle mouth 3 includes a first annular portion 31 and a second annular portion 32, and the first annular portion 31 is located above the second annular portion 32. The first annular portion 31 has an outer diameter smaller than that of the second annular portion 32, and a step 33 is formed between the first and second annular portions 31 and 32. The second annular portion 32 is provided with external threads 321, the bottle cap 2 includes a sealing groove 21, a sealing ring 22 is arranged in the sealing groove 21, the first side wall 211 of the sealing groove 21 is provided with matching threads 23, and the matching threads 23 correspond to the external threads 321. The first annular portion 31 is located in the receiving groove 21, the first annular portion 31 abutting against the sealing ring 22. In the above technical solution, by forming the step portion 33 between the first annular portion 31 and the second annular portion 32, the milk 10 remaining at the outlet above the first annular portion after drinking can be stopped by the step portion 33, so that the milk does not flow onto the external thread 321 of the second annular portion 32, and the milk is prevented from flowing onto the body of the nursing bottle. Furthermore, by providing the sealing groove 21, the first annular portion 31 can be accommodated in the sealing groove 21, and by providing the sealing ring 22, the risk of milk flowing out of the nursing bottle can be reduced. Through above-mentioned technical scheme, can further strengthen the leakproofness of feeding bottle, simultaneously, can avoid drinking the milk flow direction bottle that remains in the bottleneck after.
In this embodiment, the step portion 33 has an inclined surface 331, the first annular portion 31 has a vertical wall surface 311, and an included angle a between the vertical wall surface 311 and the inclined surface 331 is greater than 90 ° and smaller than 140 °, so as to avoid that an inclination angle of the step portion 33 is too large, which results in that a blocking effect cannot be achieved.
In this embodiment, the sealing ring 22 has the extending portion 221, and the extending portion 221 is located on the side surface of the first annular portion 31 and abuts against the step portion 33, so that the end portion of the sealing ring 22 can be attached to the step portion 33, and the sealing ring has a better sealing effect.
In this embodiment, the second annular portion 32 is provided with an annular barrier strip 322, and the annular barrier strip 322 is located below the external thread 321, so that when the remaining milk is large, the step portion 33 cannot block the downward flow of the milk, and the milk can be blocked by the annular barrier strip 322.
In this embodiment, the outer surface of the bottle cap 2 is provided with the anti-slip grooves 23, and the anti-slip grooves 23 are arranged at intervals, so that a user can hold the anti-slip grooves 23 and exert force, thereby facilitating the opening of the bottle cap. In the embodiment, the anti-slip groove extends from the top to the side of the bottle cap, so that the contact area of the anti-slip groove and fingers is increased, and the bottle cap is convenient to open.
The sealing structure of the feeding bottle can further enhance the sealing performance of the feeding bottle and avoid the leakage of milk in the feeding bottle; in addition, the milk remained on the bottle mouth can be prevented from flowing onto the bottle body along the bottle mouth after drinking.
It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, and the protection scope of the present invention cannot be limited thereby.
