Description

Technical Field

[0001] This utility model relates to the field of breastfeeding products technology, and more specifically to an anti-colic nipple. Background Technology

[0002] The conventional method for preventing colic in bottle nipples involves an air vent. When an infant sucks, the pressure inside the bottle decreases, and air is forced into the bottle through the vent to equalize the pressure, making it easier for the infant to suck. However, with this type of nipple, the cavity is often filled with milk. The air entering the bottle through the vent may react with the milk, creating air bubbles that can be swallowed by the infant, leading to colic. Therefore, there is now a type of anti-colic bottle on the market. In addition to the air vent, a vent tube is attached to the bottom of the nipple, connecting to the vent. An outlet is located at the bottom of the vent. When the infant drinks, the vent tube guides air into the bottle, reaching the bottom and equalizing the pressure inside and outside. However, in actual use, during the process of introducing air into the bottom of the bottle, the air outlet at the bottom of the air vent may be pressed against the inner wall of the bottle. This may cause the air outlet to be squeezed open and milk to enter the air vent, or it may cause the inner wall of the bottle to block the air outlet, resulting in poor airflow and making it impossible to make the pressure inside and outside the bottle consistent. In addition, there may be problems with insufficient sealing, making it easy to be contaminated by external sources.

[0003] In addition, anti-colic nipples with air tubes on the market generally adopt a separate structure for the air tube and the nipple, and may also need to be used in conjunction with other anti-colic devices. When using them, the air tube and other components are assembled onto the nipple one by one. However, this separate structure is more complex due to the large number of components, and the operation is more cumbersome. When cleaning is required, each component needs to be cleaned, which causes inconvenience in use. Utility Model Content

[0004] The purpose of this invention is to provide an anti-colic nipple with good sealing performance and effective results.

[0005] To achieve the above objectives, this utility model provides an anti-colic nipple, which is used in conjunction with a baby bottle and includes a nipple and an air guide tube. The air guide tube and the nipple are integrally formed and are integrally molded below the nipple. The nipple has an air inlet hole that penetrates through the nipple. The upper end of the air guide tube is the air inlet end, which is connected to the air inlet hole. The lower end of the air guide tube is the air outlet end, which extends to the bottom of the baby bottle. At least one one-way air outlet hole is provided on the circumferential side of the air outlet end of the air guide tube.

[0006] Furthermore, the one-way air outlet is a long strip-shaped side slit opened on the circumferential side of the air outlet end of the air duct.

[0007] Furthermore, there are two unidirectional air vents.

[0008] Furthermore, two unidirectional air outlets are symmetrically arranged on the circumferential side of the air outlet end of the air guide pipe.

[0009] Furthermore, both the nipple and the air tube are made of silicone.

[0010] Furthermore, the hardness of the air duct section is greater than that of the nipple section.

[0011] Furthermore, the nipple's inner cavity is equipped with reinforcing ribs for shaping.

[0012] Furthermore, the nipple has a thickened section around its outer perimeter that is thicker than other parts.

[0013] By adopting the above solution, this utility model has at least the following technical effects:

[0014] 1. Because the nipple and the air tube are molded as one piece, the nipple has good sealing performance and is not easily contaminated. The air tube also has a good air delivery effect. The air introduced into the bottle will not leak out through the milk from the connection between the air tube and the nipple, thus having a good anti-colic effect.

[0015] 2. Since the nipple and air tube are integrated into one structure, the structure is simple. When using the anti-colic nipple of this utility model, no additional assembly steps are required. Compared with the separate structure in the prior art, it is simple and convenient to operate and easier to clean.

[0016] 3. Since the one-way vent of the air duct is located on the circumferential side of the lower end of the air duct, it can avoid the problem of the one-way vent being blocked or squeezed open when the air duct is in the bottle due to touching or pressing against the inner wall of the bottle.

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] See Figures 1 to 4 This utility model discloses an anti-colic nipple that can be used with a baby bottle. The anti-colic nipple of this utility model includes a nipple 1 and an air guide tube 2. The air guide tube 2 is integrally formed below the nipple 1, and the air guide tube 2 and the nipple 1 are an integral structure. The nipple 1 is provided with an air inlet 11 that penetrates the nipple 1. The upper end of the air guide tube 2 is an air inlet end 21 that connects to the air inlet 11. The lower end of the air guide tube 2 is an air outlet end 23 that extends to the bottom of the baby bottle. At least one one-way air outlet 231 is opened on the circumferential side of the air outlet end 23 of the air guide tube 2.

[0025] In this embodiment, the air duct 2 and the nipple 1 are integrated into one unit, which is relatively simple. When using it, the anti-colic nipple of this embodiment can be directly assembled onto the bottle without any other assembly steps. After use, only the anti-colic nipple and the bottle need to be cleaned separately, which provides convenience for use.

[0026] When milk is filled into a bottle equipped with the anti-colic nipple of this invention, the air pressure inside and outside the bottle is equal, and the one-way vent 231 is closed, preventing milk from entering the one-way vent 231 and allowing it to flow out through the air inlet 11. During use, as the infant sucks, the amount of milk in the bottle decreases, reducing the air pressure inside. Under the influence of external atmospheric pressure, the one-way vent 231 opens, balancing the air pressure inside and outside the bottle. This allows milk to be squeezed out of the nipple 1 more easily. Furthermore, because the air guide tube 2 and the nipple 1 are integrally molded, they have good sealing properties and ensure effective air delivery. When using a baby bottle, it is usually inverted, and the bottom of the bottle will quickly run out of milk, making it difficult for milk to enter the air vent 2. In addition, this embodiment differs from the prior art by placing the one-way air outlet 231 on the circumferential side of the air vent 2 rather than the bottom of the air vent 2. This can effectively prevent the one-way air outlet 231 from being blocked by contact with the inner wall of the bottle or from being stretched open due to compression, which would affect the air delivery effect or cause milk to enter the air vent 2.

[0027] In this embodiment, the one-way air outlet 231 is a long strip-shaped side slit opened on the circumferential side of the air outlet end 23 of the air guide tube 2. It can be formed by cutting the circumferential side of the air guide tube 2 directly. The number of one-way air outlets 231 can be two. The two one-way air outlets 231 are symmetrically arranged on the circumferential side of the air outlet end 23 of the air guide tube 2, which can further ensure the ventilation function of the one-way air outlets 231.

[0028] In this embodiment, both the nipple 1 and the air duct 2 are made of silicone, and the hardness of the air duct 2 is greater than that of the nipple 1.

[0029] Preferably, the inner cavity of the nipple 1 is provided with reinforcing ribs 12 for shaping, and there are multiple reinforcing ribs 12 arranged around the inner cavity of the nipple 1.

[0030] Preferably, the nipple 1 has a thickened section 13 around its outer periphery that is thicker than other parts, so that the nipple 1 is not easily deformed or damaged.

[0031] In this embodiment, the air duct 2 has the following shape: the air inlet end 21, which connects to the air inlet hole 11, is the thickest (largest in diameter), the air inlet end 21 gradually tapers downwards to become the second thickest middle section 22, and the lower end of the middle section 22 gradually tapers downwards to become the thinnest air outlet end 23. This not only saves materials but also saves space inside the baby bottle.

[0032] The above is merely one embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
