Abstract
Description
Technical Field
[0001] This utility model relates to the field of baby bottles, and in particular to a baby bottle structure and baby bottle with an interchangeable nipple angle. Background Technology
[0002] In the field of infant feeding, the design of the baby bottle, as the primary feeding tool, directly affects the infant's feeding comfort and healthy development. Traditional baby bottles typically employ a fixed structural design, where the bottle and nipple are directly connected via threads or snaps, and the nipple's tilt angle is determined by the fixed shape of the bottle and nipple interface. However, this fixed-angle design has significant limitations: due to the different feeding scenarios (such as holding, semi-reclining, side-lying, etc.) and the varying nipple angle requirements at different stages of infant development (such as the neonatal period and the introduction of complementary foods), a fixed nipple angle may force the infant to passively adjust their sucking posture, easily leading to problems such as choking, swallowing air causing bloating, and even affecting the development of the jaw and facial features.
[0003] As infants grow, their oral structure, sucking ability, and feeding posture requirements change significantly. For example, newborns have small mouths and weak sucking power, requiring parental assistance with feeding. A tilted nipple and bottle design makes it easier for parents to hold the baby and help them grip the bottle. As infants grow older and can hold the bottle themselves, a coaxial nipple and bottle design facilitates independent sucking. Traditional baby bottles typically have nipples designed at a fixed angle, such as in upright bottles where the bottle and nipple (especially the nipple tip) are coaxial (see utility model patent CN203507159U); or in bottles with tilted nipples (see utility model patent CN219595275U). These designs cannot meet the needs of these dynamic changes, potentially leading to discomfort or health risks during feeding. To accommodate diverse feeding methods, bottle structures with adjustable nipple angles are needed. However, some improved bottles attempt to adjust the nipple angle using flexible connecting parts. For example, Chinese invention patent CN101292940A proposes an adjustable bending angle nipple and bottle. The nipple's mouth and base are integrated and made of flexible materials such as silicone. Although it can achieve a certain degree of angle deformation adjustment, it is prone to angle rebound failure due to material fatigue after long-term use, and it cannot provide stable multi-angle support. Utility Model Content
[0004] Therefore, in order to solve the above problems, this utility model provides a baby bottle structure and baby bottle with interchangeable nipple angles.
[0005] This utility model is achieved through the following technical solution:
[0006] A baby bottle structure with an interchangeable nipple angle includes a bottle body and a nipple. The nipple has a nipple head coaxially disposed on its top. The structure also includes a first connector and a second connector connecting the bottle body and the nipple. The bottle body and the nipple are connected by only one of the first connector and the second connector. When the nipple and the bottle body are connected by the first connector, the nipple and the bottle body are coaxially disposed. When the nipple and the bottle body are connected by the second connector, an angle is formed between the central axis of the nipple and the central axis of the bottle body.
[0007] Preferably, the outer periphery of the top opening of the bottle body is formed with external threads, and the bottom of the nipple is also coaxially provided with a limiting part, the limiting part including an annular limiting step and an annular limiting groove formed between the nipple and the limiting step.
[0008] Preferably, the first connector is an annular connector with a first internal thread matching the external thread on its inner circumferential wall. A first limiting ring is formed on the inner circumference of the upper opening of the first connector. When the nipple and the bottle body are connected through the first connector, the first limiting ring is embedded in the annular limiting groove, and the limiting step abuts against the bottom of the first limiting ring.
[0009] Preferably, both the upper and lower openings of the second connector are circular openings, and the second connector is a ring connector with a slope, such that the plane where the lower opening of the second connector is located is tangent to the plane where the upper opening of the second connector is located and forms an angle.
[0010] Preferably, the inner peripheral wall of the second connector is provided with a second internal thread that matches the external thread, and a second limiting ring is formed on the inner periphery of the upper opening of the second connector. When the nipple is connected to the bottle body through the second connector, the plane where the nipple and the upper opening of the second connector are located is parallel, and the second limiting ring is embedded in the annular limiting groove, and the limiting step abuts against the bottom of the second limiting ring.
[0011] Preferably, the second connector further includes a clamping member inside. The lower and upper surfaces of the clamping member are both circular, and the upper surface of the clamping member is a slope. The slope of the upper surface of the clamping member is equal to the angle between the plane containing the lower opening of the second connector and the plane containing the upper opening of the second connector. The clamping member is disposed between the second internal thread and the second limiting ring, and the upper surface of the clamping member is spaced apart from the upper opening of the second connector. When the nipple and the bottle body are connected through the second connector, the limiting step is located at the interval between the upper surface of the clamping member and the upper opening of the second connector.
[0012] Preferably, the upper surface of the clamping member has a ring of upwardly protruding limiting bosses arranged circumferentially, and the bottom of the limiting step has a ring of limiting holes that match the limiting bosses arranged circumferentially.
[0013] Preferably, the number of limiting bosses and the number of limiting holes are the same and they correspond vertically. The limiting bosses are evenly spaced on the upper surface of the clamping member, and the limiting holes are evenly spaced on the bottom of the limiting step.
[0014] A baby bottle includes a bottle body and a nipple, with a nipple head coaxially disposed at the top of the nipple. It also includes a connecting assembly connecting the bottle body and the nipple. The connecting assembly includes a connector and a clamping member. The connector is sloped such that the plane of its lower opening is tangent to the plane of its upper opening, forming an angle. The upper surface of the clamping member is sloped, and the slope of the upper surface of the clamping member is equal to the angle between the plane of the lower opening and the plane of the upper opening of the connector. The central axis of the nipple is perpendicular to the plane of the upper opening of the connector.
[0015] Preferably, the lower opening of the connector is threadedly connected to the top opening of the bottle body, the bottom of the nipple forms a limiting part, the limiting part includes an annular limiting step and an annular limiting groove formed between the nipple and the limiting step, the inner circumference of the upper opening of the connector forms a limiting retaining ring, the clamping member is disposed between the internal thread of the connector and the limiting retaining ring, and the upper surface of the clamping member is spaced apart from the upper opening of the connector, the limiting step is located at the interval between the upper surface of the clamping member and the upper opening of the connector, the upper surface of the clamping member has a ring of upwardly protruding limiting bosses arranged circumferentially, and the bottom of the limiting step has a ring of limiting holes matching the limiting bosses arranged circumferentially.
[0016] The beneficial effects of this utility model's technical solution are mainly reflected in:
[0017] 1. The device includes a first connector and a second connector. The first connector is an annular connector. The plane containing the upper surface of the second connector is tangent to the plane containing the lower surface and forms an angle. This allows the nipple and the bottle body to be coaxially arranged when connected by the first connector, facilitating the baby's independent sucking. When connected by the second connector, the central axis of the nipple and the central axis of the bottle body form an angle, and the nipple is tilted, making it easier for parents to feed the infant. This allows for diverse feeding methods without replacing the bottle body / nipple and extends the bottle's lifespan.
[0018] 2. A clamping component can also be installed inside the annular connector to ensure the firmness and sealing performance of the connection between the nipple and the second connector when the nipple is tilted. At the same time, a matching limiting connection structure can be installed at the bottom of the nipple and the upper surface of the clamping component to further ensure the connection stability between the components.
[0019] 3. This utility model also discloses another type of baby bottle, in which the nipple is inclinedly mounted on the bottle body via a connector, while the nipple is coaxially mounted on the nipple, making it convenient for parents to feed infants. At the same time, the tilting angle of the nipple is achieved through the inclined upper surface of the connector. Therefore, during feeding, the nipple does not need to be bent or deformed to tilt the nipple for feeding. Furthermore, since the nipple of this baby bottle is interchangeable with that of upright baby bottles, it is easy to replace the nipple, extending the life of the baby bottle. In addition, the tilting of the nipple is achieved through the connecting structure, which is simple in structure, easy to replace, and can reduce manufacturing costs. Attached Figure Description

[0028] To make the objectives, advantages, and features of this utility model clearer and more detailed, the following non-limiting description of preferred embodiments will be illustrated and explained. These embodiments are merely typical examples of applying the technical solutions of this utility model; any technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

They are only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0030] Furthermore, the terms "first" and "second" in this solution are used for descriptive purposes only and should not be construed as indicating or implying a ranking of importance, or implicitly specifying the number of technical features shown. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] This utility model discloses a baby bottle structure with an interchangeable nipple angle, such as... Figures 1-4 As shown, the bottle includes a bottle body 1 and a nipple 2. The nipple 2 has a nipple 201 coaxially arranged on its top. The bottle also includes a first connector 3 and a second connector 4 connecting the bottle body 1 and the nipple 2. The bottle body 1 and the nipple 2 are connected by only one of the first connector 3 and the second connector 4. Therefore, the relative angle between the nipple 2 (especially the nipple 201) and the bottle body 1 can be changed by replacing the first connector 3 and the second connector 4, thereby achieving different feeding methods. When the nipple 2 and the bottle body 1 are connected by the first connector 3, the nipple 2 and the bottle body 1 are coaxially arranged. At this time, the bottle is equivalent to a traditional upright bottle, which is convenient for older infants to suckle independently. When the nipple 2 and the bottle body 1 are connected by the second connector 4, the central axis of the nipple 2 and the central axis of the bottle body 1 form an angle. At this time, the nipple 2 (especially the nipple 201) and the bottle body 1 are tilted, which is convenient for parents to feed infants.
[0032] like Figures 3-8As shown, in some embodiments, the outer periphery of the top opening of the bottle body 1 is formed with an external thread 101, and the bottom of the nipple 2 is also coaxially provided with a limiting part. The limiting part includes an annular limiting step 202 and an annular limiting groove 203 formed between the nipple 2 and the limiting step 202. Through the above connection structure, it is convenient for the bottle body 1 and the nipple 2 to be connected to the first connecting member 3 or the second connecting member 4.
[0033] like Figure 3 , Figure 5 , Figure 6 As shown, in one embodiment, the first connector 3 is an annular connector with a first internal thread 301 on its inner circumferential wall that matches the external thread 101. A first limiting ring 302 is formed on the inner circumference of the upper opening of the first connector 3. When the nipple 2 is connected to the bottle body 1 through the first connector 3, the bottle body 1 and the first connector 3 are connected by the internal and external threads 101. The nipple 2 is connected to the first connector 3 through the limiting part at its bottom. The first limiting ring 302 is embedded in the annular limiting groove 203, and the limiting step 202 abuts against the bottom of the first limiting ring 302.
[0034] like Figure 4 , Figure 7 , Figure 8As shown, in one embodiment, both the upper and lower openings of the second connector 4 are circular. The second connector 4 is a sloping annular connector, such that the plane of the lower opening of the second connector 4 is tangent to the plane of the upper opening of the second connector 4 and forms an angle. The inner circumferential wall of the second connector 4 is provided with a second internal thread 401 that matches the external thread 101. A second limiting ring 402 is formed on the inner circumference of the upper opening of the second connector 4. When the nipple 2 and the bottle body 1 are connected through the second connector 4, the nipple 2 is parallel to the plane of the upper opening of the second connector 4, and the second limiting ring 402 is embedded in the annular limiting groove 203. The limiting step 202 abuts against the bottom of the second limiting ring 402, thereby achieving the connection between the nipple 2 and the second limiting member. In a preferred embodiment, a clamping member 5 is also provided inside the second connector 4. The lower and upper surfaces of the clamping member 5 are both circular, and the upper surface of the clamping member 5 is a slope. The slope of the upper surface of the clamping member 5 is equal to the angle between the plane where the lower opening of the second connecting member 4 is located and the plane where the upper opening of the second connecting member 4 is located. The clamping member 5 is disposed between the second internal thread 401 and the second limiting ring 402, and the upper surface of the clamping member 5 is spaced apart from the upper opening of the second connecting member 4. When the nipple 2 and the bottle body 1 are connected through the second connecting member 4, the limiting step 202 is located at the gap between the upper surface of the clamping member 5 and the upper opening of the second connecting member 4. The clamping member 5 is preferably made of a flexible material, such as rubber or silicone, to further improve the sealing performance of the connection between the nipple 2 and the second connecting member 4. The first connecting member 3 and the second connecting member 4 are both made of rigid materials, thereby ensuring the stability of the connection between the nipple 2 and the bottle.
[0035] In a preferred embodiment, the outer peripheral surfaces of the first connector 3 and the second connector 4 are both curved, thereby ensuring both aesthetics and safety when held by infants and young children.
[0036] like Figures 5-8 As shown, in some embodiments, the upper surface of the clamping member 5 has a ring of upwardly protruding limiting bosses 501 arranged circumferentially, and the bottom of the limiting step 202 has a ring of limiting holes 204 that match the limiting bosses 501 arranged circumferentially. In a preferred embodiment, the number of limiting bosses 501 and limiting holes 204 are the same and they correspond vertically. The limiting bosses 501 are equidistantly spaced on the upper surface of the clamping member 5, and the limiting holes 204 are equidistantly spaced on the bottom of the limiting step 202, thereby ensuring that all positions at the connection between the nipple 2 and the clamping member 5 are tightly connected.
[0037] like Figure 2 , Figure 4 , Figure 7 , Figure 8 As shown, this utility model also discloses a baby bottle, including a bottle body 1 and a nipple 2. A nipple tip 201 is coaxially disposed on the top of the nipple 2. The bottle also includes a connecting assembly connecting the bottle body 1 and the nipple 2. The connecting assembly includes a connector and a clamping member 5. The connector is a sloped connector, such that the plane of the lower opening of the connector is tangent to the plane of the upper opening of the connector and forms an angle. The upper surface of the clamping member 5 is a sloped surface, and the slope of the upper surface of the clamping member 5 is equal to the angle between the plane of the lower opening of the connector and the plane of the upper opening of the connector. The central axis of the nipple 2 is perpendicular to the upper opening of the connector. In a vertical plane, the bottle body 1 is coaxially connected to the lower opening of the connector, and the nipple 2 is coaxially connected to the upper opening of the connector. The connector enables the nipple 2 and the bottle body 1 to be tilted, making the bottle easier for parents to feed their infants. The nipple 2 can be the same type used for upright bottles, making it easy to replace and reducing production costs. In a preferred embodiment, the clamping member 5 is preferably made of a flexible material, such as rubber or silicone, to further improve the sealing performance at the connection between the nipple 2 and the second connector 4. The first connector 3 and the second connector 4 are both made of rigid materials, thereby ensuring the stability of the connection between the nipple 2 and the bottle.
[0038] like Figure 7 , Figure 8 As shown, in one embodiment, the lower opening of the connector is threadedly connected to the top opening of the bottle body 1. A limiting portion is formed at the bottom of the nipple 2, including an annular limiting step 202 and an annular limiting groove 203 formed between the nipple 2 and the limiting step 202. A limiting ring is formed on the inner circumference of the upper opening of the connector. The clamping member 5 is disposed between the internal thread of the connector and the limiting ring, and the upper surface of the clamping member 5 is spaced apart from the upper opening of the connector. The limiting step 202 is located at the gap between the upper surface of the clamping member 5 and the upper opening of the connector. The upper surface of the nipple 2 has a ring of upwardly protruding limiting bosses 501 arranged around its circumference. The bottom of the limiting step 202 has a ring of limiting holes 204 that match the limiting bosses 501 arranged around its circumference. The limiting holes 204 correspond vertically to the limiting bosses 501. When the nipple 2 is connected to the clamping member 5, the limiting bosses 501 are pressed into the limiting holes 204. In a preferred embodiment, the limiting bosses 501 are evenly spaced on the upper surface of the clamping member 5. The number of limiting holes 204 is the same as the number of limiting bosses 501 and they correspond one-to-one, so that the limiting holes 204 are evenly spaced at the bottom of the limiting step 202.
