[0023] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0024] Example 1

[0025] See also Figures 1 to 6 A constant pressure feeding bottle comprises a feeding bottle body 1, the feeding bottle body 1 comprises a nipple assembly 11, a bottle body 12 connected to the nipple assembly 11, and a constant pressure assembly 13 located on one side of the bottle body 12, the constant pressure assembly 13 comprising a one-way air inlet valve 131, the one-way air inlet valve 131 being provided with an air outlet 1311 communicating with the cavity of the bottle body 12, and an air inlet hole 1312 respectively communicating with the air outlet 1311 and the outside world, the one-way air inlet valve 131 guiding external air into the interior of the bottle body 12 through the air inlet hole 1312 and the air outlet 1311, so that the air pressure inside the feeding bottle remains relatively stable with the atmospheric pressure. Therefore, when the baby sucks milk and the air pressure in the bottle drops, the one-way air inlet valve 131 will introduce an appropriate amount of air to maintain the air pressure in the bottle close to the external atmospheric pressure, ensuring that the milk can flow out stably and smoothly, reducing the resistance and choking risk when the baby sucks, and the connection between the air outlet 1311 and the air inlet hole 1312 provides a channel for air circulation.

[0026] like Figures 1 to 6 The constant pressure feeding bottle shown in the figure has an elastic one-way air inlet valve 131. The one-way air inlet valve 131 includes an air outlet portion 1313 connected to the interior of the bottle body 12 and an air inlet portion 1314 connected to the outside of the bottle body. The air outlet portion 1313 is connected to the air inlet portion 1414. The air outlet 1311 is located in the air outlet portion 1313, and the air inlet hole 1312 is located in the air inlet portion 1314. The air outlet 1311 is provided with a gap 13111, and air enters the interior of the feeding bottle through the gap 13111. With such a design, since the one-way air inlet valve 131 is made of elastic material, the one-way air inlet valve 131 can be adjusted to open and close according to the change of pressure in the bottle, and the gap 13111 serves as a valve to control the airflow in and out. When the pressure difference between the inside and outside of the bottle is small, the gap 13111 is in a closed and sealed state. Conversely, when the pressure difference becomes larger, the gap 13111 is in an open state, allowing air to slowly enter through the tiny gap under the action of negative pressure, which not only ensures the balance of air pressure, but also avoids the problem of milk splashing or excessive bubbles caused by a large amount of air rushing in at one time. Such a design can better control the amount of air entering, making the baby's sucking experience smoother.

[0027] like Figures 1 to 6 The constant pressure feeding bottle shown in the figure has a first connecting hole 132 on one side of the bottle body 12 for the air outlet to extend into, and the constant pressure assembly 13 includes a positioning piece 133 connected to the one-way air inlet valve 131, and a second connecting hole 134 located on the positioning piece 133, the second connecting hole 134 is for the air outlet 1313 to pass through and is sleeved on the outside of the air outlet, the one-way air inlet valve 131 passes through the second connecting hole 134 and the first connecting hole 132, so that the one-way air inlet valve 131 is connected to the positioning piece 133 and the bottle body 12 respectively. Furthermore, by aligning and connecting the first connecting hole 132 and the second connecting hole 134, an air flow channel is formed that runs through the inside and outside of the bottle body 12, and the positioning member 133 connects the one-way air inlet valve 131 and the bottle body 12, which not only fixes the one-way valve 131, but also ensures the sealing effect of the constant pressure assembly. The one-way air inlet valve 131 passes through the first connecting hole 132 and the second connecting hole 134, thereby achieving a stable connection between the one-way air inlet valve 131 and the bottle body 12.

[0028] like Figures 1 to 6In the constant pressure feeding bottle shown, the one-way air inlet valve 13 further includes an alignment hole 135. The alignment member 133 is used to support the one-way air inlet valve 131. The outer ring of the alignment member 133 is provided with a plurality of evenly distributed protrusions 1331. The alignment holes 135 correspond one-to-one with the protrusions 1331. The protrusions 1331 are connected to the alignment holes 135, so that the alignment member 133 is fixedly connected to the one-way air inlet valve 131. By providing the alignment holes 135 on the one-way air inlet valve 131 and connecting with the protrusions 1331, the accurate positioning and airtightness of the one-way air inlet valve and the alignment member 133 are ensured, and the overall structure is also made more stable and not easily loosened by external forces.

[0029] like Figures 1 to 6 In the constant-pressure feeding bottle shown, the constant-pressure assembly 13 also includes a bottom cover 136, with a gas stopper 1361 positioned in the center. This gas stopper 1361 engages with the air inlet 1312. This design not only supports the bottom but also seals the air inlet 1312. The gas stopper 1361 blocks the air inlet 1312, sealing the one-way air inlet valve 131 when the feeding bottle is not in use. This prevents the bottle from being shaken and leaking liquid. This also ensures that the one-way air inlet valve 131 is clean.

[0030] like Figures 1 to 6A constant pressure feeding bottle is shown, the nipple assembly 11 includes a suction head 111, an areola area 112 located below the suction head 111, a base 113 located below the areola area 112, and a locking ring 114. The inner side of the suction head 111 is provided with several annular protrusions 1111, the areola area 112 is provided with a nipple shield 1121 extending from the inner side of the suction head 111 to the outer side of the suction head 111, a hollow area 115 is provided between the areola area 112 and the base 113, the base 113 is provided with an annular groove 1131, the areola area 112 is provided with a plurality of protrusions 1122 evenly distributed around the suction head 111, and the feeding bottle body 1 also includes a bottle cap 14 connected to the bottle body 12. The design of the annular protrusion 1111 can support the suction head 111, preventing the baby from being unable to suck out the milk normally due to the collapse of the suction head during the sucking process, and the nipple shield 1121 can better adapt to the baby's sucking action, providing a shape and texture similar to the mother's breast, allowing the baby to better adapt to using a feeding bottle. Furthermore, the hollow area 115 allows the suction head 111 to deform within a certain range, and the annular groove 1131 allows the suction head 111 to move in a certain vertical direction to adapt to different sucking angles of the baby and provide better sucking comfort. The design of the convex point 1122 can further imitate the touch of breastfeeding, and at the same time can stimulate the baby's tongue and the inside of the mouth to a certain extent, which helps the baby to produce a sucking reflex and swallowing coordination. The bottle cap 14 can keep the nipple assembly 11 clean.

[0031] like Figures 1 to 6 In the constant pressure feeding bottle shown, the base 113 further includes a slot 1132 provided at the bottom of the base 113. The slot 1132 matches the shape of the locking ring 114. The locking ring 114 is inserted into the slot 1132 to connect the base 113 with the locking ring 114. The inner side of the locking ring 114 is provided with a locking ring thread 1141, and the outer side of the bottle body 12 is provided with a bottle body thread 121 that matches the locking ring thread 1141. The cooperation between the slot 1132 and the upper end of the locking ring 114 can effectively ensure the sealing of the nipple assembly and prevent the possibility of milk leakage at the connection between the base 113 and the locking ring 114. The cooperation between the locking ring thread 1141 and the bottle body thread 121 ensures the sealing of the nipple assembly 11 and the bottle body 12. At the same time, the threaded connection method also provides better structural stability for the feeding bottle.

[0032] like Figures 1 to 6In the constant pressure feeding bottle shown, the cross-section of the air outlet portion 1313 is a first trapezoid 13131, the cross-section of the air inlet portion 1314 is a rectangle 13141, the length of the lower base of the first trapezoid 13131 is greater than or equal to the length of the long side of the rectangle 13141, and the length of the long side of the rectangle 13141 is greater than or equal to the diameter of the first connecting hole 132. The cross-section of the air outlet 1313 is designed to be trapezoidal, which can reduce the pressure required for air to enter the bottle while increasing the pressure required for the liquid and air in the bottle to overflow from the air outlet 1313, thereby better controlling the one-way entry of air. The design that the lower base length of the first trapezoid 13131 is greater than or equal to the long side of the rectangle 13141 and the length of the long side of the rectangle 13141 is greater than or equal to the diameter of the first connecting hole 132 is for the one-way air inlet valve 131 to be interference fit with the first connecting hole 132 and the second connecting hole to improve the sealing of the bottle. Furthermore, the air outlet 1313 can be engaged with the inner cavity of the bottle body 12, and the lower base length of the first trapezoid 13131 limits the air outlet 1313 from being separated from the first connecting hole 132, thereby fixing the one-way air inlet valve 131.

[0033] like Figures 1 to 6 The constant pressure feeding bottle shown in the figure has a cross-section of the air outlet 1311 being a second trapezoid 13112, the gap 13111 being located on the upper bottom surface of the second trapezoid 13112, the outer peripheral side of the air inlet portion 1314 being provided with a fitting block 13141 abutting against the bottom of the bottle body 12, an extension block 13142 being provided on the lower side of the fitting block 13141, the alignment hole 135 and the air inlet 1312 passing through the extension block 13142, the cross-sections of the fitting block 13141 and the extension block 13142 being circular, and the outer diameter of the fitting block 13141 being larger than the outer diameter of the extension block 13142. Furthermore, the trapezoidal cross-section of the air outlet 1311 can facilitate the installation of the one-way air inlet valve 131 when combined with the property that the one-way air inlet valve is made of elastic material, while achieving better sealing. The design of the fitting block 13141 abutting against the bottom of the bottle body 12 provides more layers of sealing protection, thereby ensuring the tightness of the connection between the one-way air inlet valve 131 and the bottle body 12 to a greater extent.

[0034] like Figures 1 to 6In the constant-pressure feeding bottle shown, the one-way air inlet valve 131 is provided with a receiving groove 1315 for accommodating the alignment member 133. The receiving groove 1315 is located between the fitting block 13141 and the air inlet portion 1314. The alignment hole 135 is located within the receiving groove 1315. The upper end surface of the alignment member 133 is flush with the upper end surface of the receiving groove 1315. The flush design of the upper end surface of the alignment member 133 and the upper end surface of the receiving groove 1315 enables a seamless connection between the air inlet portion 1314 and the alignment block 135, making the structure of the constant-pressure assembly 13 more compact and stable.

[0035] When using a constant pressure bottle for feeding, first open the bottle cap 14 and the bottom cover 136. When the baby sucks the milk, negative air pressure is generated in the bottle. At this time, air will pass through the channel of the air inlet 1312 and the air outlet 1311. The closed gap 13111 will open under the action of the negative air pressure, and air will enter the bottle through the gap 13111 to make the air pressure inside and outside the bottle the same. When the baby stops sucking, negative air pressure is no longer generated in the bottle, and the gap 13111 will return to the closed state.

[0036] The above examples are merely used to further illustrate the technical content of the present invention for easier understanding by the reader. However, they do not limit the implementation of the present invention to these examples. Any technical extension or reinvention based on the present invention is protected by the present invention. The scope of protection of the present invention shall be determined by the claims.
