Description

TECHNICAL FIELD

[0001] The utility model relates to a feeding bottle, in particular to an anti-gas feeding bottle. BACKGROUND

[0002] The existing feeding bottle is generally composed of a bottle body and a nipple, wherein the bottle body is used for containing milk, and the nipple is used for feeding a baby. When the baby sucks the nipple to eat, the feeding bottle is generally in an inclined or inverted state. Once part of the milk is sucked out, negative pressure will be generated in the bottle body, thereby hindering the further sucking out of the milk, which will seriously affect the eating speed and eating experience of the baby. To solve this problem, the parents need to take out the nipple from time to time when feeding, so that air enters the bottle through the nipple opening to solve the problem of negative pressure in the bottle. This not only is troublesome to operate, but also the air entering through the nipple will mix with the milk to generate a large amount of bubbles. Once the baby sucks in the milk with bubbles, the baby is prone to choke and gas problems, which has great safety hazards. SUMMARY

[0003] In view of the above problems, the utility model designs an anti-gas feeding bottle. A one-way air inlet anti-gas structure is arranged at the bottom of the bottle body, which can fundamentally solve the problem of negative pressure when the baby is fed, and can realize continuous feeding. The anti-gas feeding bottle has the characteristics of simple structure and practicality.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] An anti-gas feeding bottle, comprising a bottle body and a nipple, characterized in that: a lower opening is arranged at the bottom of the bottle body, a silica gel sheet and a bottom cover are sequentially arranged at the bottom of the lower opening, a connecting edge is arranged at the periphery of the bottom cover, and the inner side of the connecting edge is connected with the outer side of the lower opening of the bottle body through threads; at least one air return structure is arranged on the silica gel sheet, each air return structure comprises an air inlet, an air inlet channel and an air return valve, the air inlet is arranged on the outer side of the silica gel sheet and is in communication with the threads on the connecting edge of the bottom cover, the air inlet channel is arranged on the bottom surface of the silica gel sheet and is used for connecting the air inlet and the air return valve, and at least one vertical cut is arranged on the side wall of the valve body of the air return valve in the circumferential direction. In the normal state, the cut is closed and not opened, and when negative pressure is generated in the bottle body, the cut is opened by external air to realize air return.

[0006] More specifically, the valve body of the air return valve is in a cylindrical shape, and the top of the valve body is semicircular.

[0007] More specifically, a plurality of air return structures are arranged at equal intervals in the circumferential direction.

[0008] More specifically, the height of the air inlet channel is not more than 1mm.

[0009] More specifically, a connecting groove is arranged at the contact part of the silica gel sheet and the bottom of the lower opening of the bottle body.

[0010] During use, once negative pressure is generated inside the bottle, external air reaches the return air valve through the threaded gaps in the bottom cap, the air inlet, and the air intake channel. The pressure difference between the inside and outside forces the return air valve to open the vent and enter the bottle, keeping the internal air pressure balanced and ensuring normal milk intake. Throughout the use of the bottle, there is no need to frequently remove the nipple for ventilation, and it will not cause air to mix with the milk and produce a large number of bubbles, thus avoiding choking and bloating problems for the baby.

[0017] like Figures 1-5 As shown, an anti-colic baby bottle includes a bottle body 1 and a nipple 2. The nipple 2 is fixed to the upper opening of the bottle body 1 by a top cover. At the same time, for dust prevention, the nipple 2 is provided with a dust cover.

[0018] The bottom of the bottle body 1 is provided with a straight lower opening 11. The lower opening 11 is provided for setting up the corresponding return air structure 3, and also improves the convenience of cleaning the inside of the bottle body 1.

[0019] The bottom of the lower opening 11 of the bottle is sealed by a silicone sheet 4 and a bottom cap 5. The bottom cap 5 has a connecting edge 51 around its perimeter, and the inner side of the connecting edge 51 has an internal thread 511. This internal thread 511 connects with the external thread 111 on the outer side of the lower opening 11 of the bottle. In use, tightening the bottom cap 5 will allow the silicone sheet 4 to be firmly held against the bottom of the lower opening 11, thus achieving an effective seal and preventing leakage.

[0020] To further improve the sealing performance between the silicone sheet 4 and the lower opening 11 of the bottle, the silicone sheet 4 is provided with a connecting groove 41 at the contact point with the bottom of the lower opening 11 of the bottle. The connecting groove 41 is provided for the installation and positioning of the silicone sheet 4, which facilitates disassembly and assembly. At the same time, it can also increase the sealing contact area between the silicone sheet 4 and the bottom of the lower opening 11 of the bottle, thereby improving the sealing effect.

[0021] The silicone sheet 4 is provided with at least one air return structure 3. In this figure, only two air return structures 3 are described. In practice, one or more air return structures 3 can also be provided as needed. The technical principle and technical effect are the same, and will not be described again here.

[0022] Each return air mechanism 3 includes an air inlet 31, an air inlet channel 32, and a return air valve 33. The air inlet 31 is located on the outside of the silicone sheet 4 and is threadedly connected to the bottom cover connecting edge 51. The air inlet channel 32 is located on the bottom surface of the silicone sheet 4 to connect the air inlet 31 and the return air valve 33. The valve body side wall of the return air valve 33 has at least one vertical cut 331 along the circumferential direction. In this figure, only the structure with two cuts 331 is described. In practice, one or more cuts can be set as needed. The technical principle and technical effect are the same, and will not be described again here.

[0023] Under normal conditions, the incision 331 remains closed and will not leak milk. However, when negative pressure is generated inside the bottle 1, the incision 331 is forced open by external air to allow for normal air return.

[0024] When the bottle 1 is tilted or inverted for feeding, once negative pressure is generated inside the bottle 1, external air enters through the threaded gap of the bottom cover 5, passes through the air inlet 31 and air inlet channel 32 of the silicone sheet 4, reaches the return air valve 33, and breaks through the cut 331 of the return air valve 33 to enter the bottle, so as to keep the air pressure inside the bottle 1 balanced and ensure the normal suction of milk.

[0025] The above-mentioned venting structure eliminates the need to frequently remove the nipple 2 for venting during bottle use, and also prevents air from mixing with milk and generating a large number of bubbles, thus effectively avoiding choking and gas problems for infants.

[0026] Here, in order to ensure a stable and balanced return air pressure, when multiple return air structures 3 are provided, each return air structure 3 is distributed at equal intervals along the circumferential direction at the bottom of the silicone sheet 4.

[0027] The valve body of the return air valve 33 is cylindrical with a semi-circular top. This structure can effectively disperse the pressure of the milk and prevent the return air valve 33 from deforming and causing leakage.

[0028] During the tightening of the bottom cover 5, the air intake channel 32 will be squeezed to form an arch effect. In order to avoid excessive compression and deformation and to ensure normal air intake, the height of the air intake channel 32 is set to not exceed 1mm.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
