Description

Technical Field

[0001] The utility model relates to a feeding bottle, in particular to an anti-flatulence feeding bottle which is mainly suitable for babies. Background Art

[0002] A baby bottle is a must-have for most infants and young children. Current baby bottles mainly include a bottle body, a nipple and a tooth cap. For babies who are just born or a few months old, the baby bottles usually do not contain straws. The baby is fed through the nipple on the bottle, that is, the baby bottle is tilted and used upside down when feeding. For the baby bottles used upside down, the current air return hole of the baby bottle is on the nipple. During use, the gas directly enters the milk near the nipple from the air return hole, which can easily cause bloating in children.

[0003] CN208877345U discloses a nursing milk bottle and an air return pipe, in which an air guide pipe is arranged inside the bottle body, and the lower end of the air guide pipe extends to the bottom of the bottle body. The lower end of the air guide pipe is an opening, i.e., an air guide hole. When preparing milk powder, it is easy for milk powder or milk liquid to enter the air guide pipe, resulting in dirt hidden inside the air guide pipe, which affects hygiene. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an anti-flatulence feeding bottle.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An anti-flatulence baby bottle comprises a bottle body, a nipple is arranged on the bottle body, an air guide tube is arranged inside the bottle body, the upper end of the air guide tube extends to one side of the nipple and is connected with the outside, the lower end of the air guide tube extends to the bottom of the bottle body, and an air return valve is arranged at the lower end of the air guide tube. The cross section of the air return valve is V-shaped, and the air return valve remains in a closed state when not subjected to pressure.

[0007] As a further improvement, the air return valve is integrally formed at the lower end of the air guide pipe.

[0008] As a further improvement, the air guide tube is arranged on a non-central side of the bottle body.

[0009] As a further improvement, the air guide tube is made of food-grade silicone material.

[0010] As a further improvement, the hardness of the air guide pipe and the air return valve is set to 45-65 degrees.

[0011] As a further improvement, a through hole is provided on one side of the feeding bottle, and the upper end of the air guide tube is installed in the through hole.

[0012] As a further improvement, the hardness of the nipple is set to 20-25 degrees.

[0013] The utility model arranges an air return valve at the lower end of the air guide tube, and the air return valve has a one-way conduction function, thus forming a function similar to a one-way valve. When the feeding bottle is inverted for sucking, the air return valve will not contact the milk. As the baby continues to suck, the milk in the bottle body continues to decrease. During the reduction process, the volume of the cavity inside the bottle body increases and the air pressure decreases. At this time, external air will enter through the air guide tube. Due to the large external pressure, the air return valve will be opened to allow gas to enter the inside of the bottle body, thereby maintaining the balance of internal and external air pressures and ensuring normal sucking. Since the air return valve is located at the bottom of the bottle body, the air entering the bottle body is always located between the milk and the bottom of the bottle and will not be sucked by the baby, thus playing an anti-flatulence role.

[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0017] In the description of the present utility model, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like are involved, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0018] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium. It can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] like Figure 1 and 2 As shown, the utility model discloses an anti-flatulence baby bottle, comprising a bottle body 1, a nipple 2 is arranged on the bottle body 1, an air guide tube 3 is arranged inside the bottle body 1, the upper end of the air guide tube 3 extends to one side of the nipple 2 and is connected to the outside, the lower end of the air guide tube 3 extends to the bottom of the bottle body 1, and the lower end of the air guide tube 3 is provided with a return valve 4, the cross section of the return valve 4 is V-shaped, and the return valve remains in a closed state when not under pressure. Since the return valve is V-shaped, it forms a function similar to a one-way valve. When the bottle body is filled with water, the return valve is immersed in water, and water will not enter the air guide tube from the return valve. Therefore, the return valve is in a closed state at this time and will not hide dirt. Only when the pressure inside the bottle body is less than the external air pressure, the external gas enters the air guide tube, and then the pressure difference is used to prop up the return valve, so that the gas enters the bottle body through the return valve, maintains the air pressure balance inside and outside the bottle body, and ensures normal inhalation.

[0020] The air return valve 4 is integrally formed at the lower end of the air guide pipe 3 and is made of food-grade silicone material.

[0021] The air guide tube is arranged on a non-central side of the bottle body to avoid affecting normal use.

[0022] In addition, the hardness of the air guide tube and the air return valve is set to 45-65 degrees, and the preferred solution is to choose 55 degrees, which is the most ideal hardness for the air return effect. In the specific production, the air guide tube is first injection molded, and then the air guide tube is placed on the pacifier mold. The hardness of the pacifier is 22 degrees, which feels soft and sticky, and the taste of the baby is close to breast milk when sucking.

[0023] When preparing the product, different colors can be set for easy distinction. Air tubes of different colors represent nipples at different stages, pink for newborns, blue for the second stage, and green for the third stage. The nipple has a transparent body, so that users can distinguish it at a glance.

[0024] In addition, for the nipple, a through hole is provided on it for convenient sucking, which is a known technology. In the present application, one hole, two holes, three holes, or other number of holes can be selectively provided. The diameter of the hole can also be flexibly set, such as 0.6 mm, or other hole diameters, which are not specifically limited here.

[0025] The specific principle of the utility model is:

[0026] When the baby is sucking, the bottle needs to be turned upside down and tilted. As the baby continues to suck, the liquid in the bottle decreases, the space at the bottom of the bottle becomes larger and larger, and the pressure in the bottle also decreases. At this time, in order to be able to suck normally, the external air pressure is higher, and the gas will enter the air guide tube, and then the return air valve will be opened to allow the gas to enter the bottle smoothly, maintaining the air pressure balance inside and outside the bottle. The gas directly enters the bottom of the bottle and will not enter the liquid in the bottle, so it will not be inhaled into the baby's mouth, which can play a role in preventing flatulence.

[0027] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
