Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of maternal and child products, in particular to a nipple with air return function and a feeding bottle. BACKGROUND

[0002] When the infant uses the feeding bottle to eat, if too much air is taken in, it is easy to cause the problem of bloating. In order to solve this problem, some feeding bottles reduce air intake by designing an air return hole on the nipple. A valve is usually arranged in the air return hole to realize the air return function when sucking. However, in the existing nipple design, the air return hole is mostly located at the areola part of the nipple. This structure has the following disadvantages: first, when the baby sucks milk, the face is easy to block the air return hole, which causes the air return to be not smooth; second, the air return valve is close to the sucking head. When the baby bites the sucking head, the air return valve is easy to deform, so it cannot be completely closed, causing liquid leakage. In addition, the air return hole is exposed, which also affects the appearance of the nipple. SUMMARY

[0003] Therefore, it is necessary to provide a nipple with air return function and a feeding bottle to solve the problems of the existing nipple, ensure smooth air return, reduce liquid leakage, and improve the appearance effect.

[0004] A nipple with air return function comprises:

[0005] an areola part having a cavity;

[0006] a sucking head protruding from the upper end of the areola part;

[0007] a base part connected to the lower end of the areola part, and an annular groove is arranged on the outer peripheral surface of the base part;

[0008] an air return valve comprising an air return port;

[0009] The air return port is located on the inner wall of the annular groove, and an air groove is formed on the inner wall of the annular groove, which connects the air return port with the outside.

[0010] In one embodiment, the inner wall of the annular groove comprises a bottom wall, a lower side wall and an upper side wall, the air groove comprises a first groove arranged on the bottom wall and a second groove arranged on the lower side wall and / or the upper side wall, one end of the second groove communicates with the first groove, and the other end penetrates to the outer surface of the base part, and the air return port is partially or entirely located on the bottom wall of the first groove.

[0011] In one embodiment, the air return port is located on the bottom wall of the first groove close to one side of the lower side wall.

[0012] In one embodiment, the width of the first groove is greater than the width of the air return port in the circumferential direction.

[0013] In one embodiment, the second groove extends radially.

[0014] In one embodiment, the return air port is a strip-shaped structure extending in a circumferential direction.

[0015] In one embodiment, the suction head is tilted to one side of the areola relative to the axis of the areola, and the air vent is located on the inner wall of the annular groove opposite to the tilting direction.

[0016] In one embodiment, the return air valve includes a valve body having a valve cavity, one end of which is connected to the return air port, and the other end of which is provided with a valve hole.

[0017] In one embodiment, the valve body extends radially along the valve body.

[0018] A baby bottle includes a bottle cap and a nipple with a venting function. The bottle cap has an annular rib that mates with the annular groove. The surface of the annular rib mates with the air groove to form an air passage that connects the venting port to the outside.

[0019] The aforementioned pacifier with venting function effectively overcomes the shortcomings of existing technologies by placing the venting port on the inner wall of the annular groove in the base. Specifically, this design has the following technical effects:

[0020] 1. Prevent the air vent from being blocked: Since the air vent is located on the inner wall of the annular groove in the areola, rather than near the areola head, it prevents the baby's face or mouth from blocking the air vent while sucking, thus ensuring that the air venting function works properly, reducing air intake, and lowering the risk of bloating.

[0021] 2. Preventing deformation of the vent valve: The vent valve is located away from the sucking head, making it less likely for the baby to come into contact with or bite the vent valve during sucking. This avoids vent valve failure caused by deformation of the sucking head, ensuring that the vent valve can open and close normally and effectively preventing liquid leakage.

[0022] 3. Aesthetics: The vent is hidden in the inner wall of the annular groove, reducing exposed structures and maintaining the overall appearance of the nipple. It also avoids hygiene problems caused by exposed vent holes. Attached Figure Description

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] See Figure 1 , 2In one embodiment of this utility model, the nipple 10 with a venting function includes: an areola 11, a sucking head 12, a base 13, and a venting valve 15. The areola 11 has a cavity 111. The sucking head 12 protrudes from the upper end of the areola 11. As an example, the sucking head 12 has a head and a neck. A through hole is provided at the center of the top of the head. The neck connects the head and the areola 11, and has a channel for liquid passage. One end of the channel communicates with the cavity 111 of the areola 11, and the other end communicates with the through hole on the head. The base 13 is connected to the lower end of the areola 11. An annular groove 14 is provided on the outer circumferential surface of the base 13. This annular groove 14 cooperates with an annular rib 21 on the bottle cap 20 to connect the nipple 10 to the bottle cap 20. The vent valve 15 includes a vent 146 located on the inner wall of the annular groove 14, and an air groove is formed on the inner wall of the annular groove 14, which connects the vent 146 to the outside. When the baby is sucking, the pressure inside the bottle decreases, and the vent valve 15 automatically opens, allowing air to enter the bottle through the air groove and the vent 146. In this way, outside air enters the bottle through the vent valve 15, replenishing the pressure drop caused by the liquid outflow, thereby maintaining the pressure inside the bottle close to the outside pressure.

[0032] The pacifier 10 with venting function provided in this application effectively solves the shortcomings of the prior art by setting the venting port 146 on the inner wall of the annular groove 14 of the base 13. Specifically, this design has the following technical effects:

[0033] 1. Preventing the air vent 146 from being blocked: Since the air vent 146 is located on the inner wall of the annular groove 14 of the areola 11, rather than near the areola 11 of the sucking head 12, it prevents the baby's face or mouth from blocking the air vent 146 when sucking, thereby ensuring that the air venting function works normally, reducing air intake, and reducing the risk of bloating.

[0034] 2. Preventing deformation of the vent valve 15: The vent valve 15 is located away from the sucking head 12, making it difficult for the baby to come into contact with or bite the vent valve 15 during sucking. This avoids the vent valve 15 from failing due to deformation of the sucking head 12, ensuring that the vent valve 15 can open and close normally and effectively preventing liquid leakage.

[0035] 3. Aesthetics: The air vent 146 is hidden in the inner wall of the annular groove 14, reducing exposed structures and maintaining the overall aesthetic appearance of the nipple 10, while avoiding hygiene problems caused by exposed air vents.

[0036] In one embodiment, the inner wall of the annular groove 14 includes a bottom wall 141, a lower side wall 142, and an upper side wall 143. The gas groove includes a first groove 144 disposed on the bottom wall 141 and a second groove 145 disposed on the upper side wall 143. One end of the second groove 145 communicates with the first groove 144, and the other end extends to the outer surface of the base 13. The return air port 146 is located on the bottom wall of the first groove 144. By designing grooves on the bottom wall 141 and the upper side wall 143 of the annular groove 14, gas return can be effectively guided, avoiding the influence of negative pressure on liquid flow. As an alternative, the second groove 145 can be disposed on the lower side wall 142, or simultaneously disposed on both the upper side wall 143 and the lower side wall 142.

[0037] In one embodiment, the vent 146 is located on the bottom wall of the first groove 144 on the side near the lower sidewall 142. The advantage of this design is that the vent 146 is closer to the lower end face of the nipple 10, preventing it from being blocked by the baby's face or fingers, thus ensuring smooth venting. Simultaneously, the vent valve 15 is located away from the sucking head 12, making it less likely for the baby to come into contact with or bite the vent valve 15 during sucking, preventing vent valve 15 from malfunctioning due to deformation of the sucking head 12.

[0038] In one embodiment, the width of the first groove 144 is greater than the width of the vent 146 in the circumferential direction. Because the width of the first groove 144 is greater than the width of the vent 146, when the pressure inside the bottle decreases, outside air can quickly enter the vent 146 through the first groove 144, achieving a rapid venting function. At the same time, the larger width of the first groove 144 ensures that the airflow is not restricted before entering the vent 146, improving venting efficiency.

[0039] In one embodiment, the second groove 145 extends radially. The radially extending design of the second groove 145 allows air to enter the bottle quickly and directly, improving the efficiency of the venting function and ensuring that the air pressure inside and outside the bottle can be quickly balanced.

[0040] In one embodiment, the vent 146 is a strip-shaped structure extending circumferentially. The strip-shaped vent 146, by extending circumferentially, allows more air to enter the bottle in a short time, preventing negative pressure from forming due to insufficient air intake during infant feeding. Simultaneously, the strip-shaped design effectively prevents liquid leakage through the vent 146, ensuring the bottle's airtightness.

[0041] In one embodiment, the sucking head 12 is tilted to one side of the areola 11 relative to its axis, and the vent 146 is located on the inner wall of the annular groove 14 opposite to the tilt direction. By placing the vent 146 on the opposite side of the tilt direction, it avoids obstruction by the baby's face, mouth, or fingers, ensuring that the venting channel remains unobstructed. This design ensures smooth airflow into the bottle, maintains pressure balance inside and outside the bottle, and prevents negative pressure buildup.

[0042] In one embodiment, the return air valve 15 includes a valve body having a valve cavity, one end of which communicates with the return air port 146, and the other end of which is provided with a valve hole (not shown in the figure). The valve body extends radially along the valve body.

[0043] like Figure 3 , 4 In another embodiment of this application, a baby bottle is provided, including a bottle cap 20 and a nipple 10 with a venting function as described in the above embodiment. The bottle cap 20 has an annular rib 21 that mates with an annular groove 14. The surface of the annular rib 21 mates with the air groove to form an air passage 30 that connects the venting port 146 to the outside. When the baby is sucking, the pressure inside the bottle decreases, and the venting valve 15 automatically opens, allowing air to enter the bottle through the air passage 30. In this way, outside air enters the bottle through the venting valve 15, replenishing the pressure drop caused by the liquid outflow, thereby maintaining the pressure inside the bottle close to the outside pressure.

[0044] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
