[0030] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0031] Figure 1 Schematic cross-sectional view of a nipple according to an embodiment of the present disclosure. As Figure 1 shown, the nipple includes: a sucking part 10, a flared part 20, and a liquid outlet 30. The liquid outlet 30 is provided at the top end of the sucking part 10. The liquid outlet 30 includes a plurality of slits 31. The same slit 31 includes a first section 320 and a second section 330 that are connected. Among them, the ends of the first sections 320 of each slit 31 that are far from the second sections 330 are collinear, and the second sections 330 of each slit 31 are isolated from each other; the extending direction of the first section 320 of the same slit 31 is different from the extending direction of the second section 330, and the curvatures of the first section 320 and the second section 330 are the same.

[0032] In the embodiment of the present disclosure, the sucking part 10 has an axisymmetric structure, and the center of the top end of the sucking part 10 is on this axis. One end of the flared part 20 has an opening, and the other end is integrally connected to the sucking part 10. The sucking part 10 and the flared part 20 together form a hollow cavity. Liquid can flow into the hollow cavity from the opening of the flared part 20 and can flow out from the liquid outlet 30 of the sucking part 10.

[0033] As Figures 2 - 7 shown, the liquid outlet 30 includes a plurality of slits 31. During specific implementation, the number of slits 31 is not limited. Optionally, the number of slits 31 is 3 to 6, such as 3, 4, 5, 6. In the embodiment of the present disclosure, Figure 2 、 Figure 3 both shown are 3 slits 31, Figures 4 - 7 both shown are 4 slits 31. Specifically, the number of slits can be adjusted according to needs, which can adapt to infants of different ages and sucking strengths and meet different feeding requirements.

[0034] According to the solution of the embodiment of the present disclosure, 3 to 6 slits 31 can reduce the resistance during a baby's sucking, making the feeding process easier. Additionally, multiple slits 31 disperse the stress, such that the stress borne by each slit 31 is small, reducing the risk of tearing and damage. The design with a moderate number of slits 31 can maintain the stability of the overall structure of the nipple.

[0035] As Figure 2 shown, the same slit 31 includes a first section 320 and a second section 330 that communicate with each other. Among them, the first section 320 and the second section 320 may be directly connected, or may be connected through other sections located between the first section 320 and the second section 330, which is not limited here.

[0036] As Figures 2 - 7 shown, one end 32 of the first section 320 of each slit 31 away from the second section 330 is common, and the second sections 330 of each slit 31 are isolated from each other. Specifically, one end 32 of each slit 31 containing the first section 320 is common, that is, multiple slits 31 intersect at the same position on the nipple, and this position (the position where the common point is located) may be at the center of the top of the sucking part 10. Each slit 31 communicates with each other at the common point, that is, the liquid can flow out through the opening formed at the communicating common point. That is to say, each slit 31 intersects at the common point, and multiple slits 31 extend diffusely around with this common point as the center. The second sections of each slit 31 are isolated from each other. When the user sucks the sucking part 10, a pressure difference is formed between the hollow cavity and the outside, such that at least one slit is opened, and the liquid flows out through the liquid outlet 30. When the pressure difference disappears or is insufficient, the slit in the liquid outlet 30 closes.

[0037] The first section 320 is a part of the slit 31 containing the common point, which can be understood as the part at the starting position of the slit 31. The second section 330 is the part at the ending position of the slit 31. Since the extending directions of the first section 320 and the second section 330 in each slit 31 are different, an included angle can be formed between the extending direction of the first section 320 of the slit 31 and the extending direction of the second section 330 of the slit 31. That is to say, the extending directions of the head and tail two line segments of the slit are different, such that the force at the ending position of the slit 31 is dispersed or reduced, and the milk outlet 30 of the nipple is not easily torn when the user uses it, improving the service life of the nipple.

[0038] It should be noted that when the first section 320 and / or the second section 330 of the slit 31 is a straight slit, its extending direction is the extending direction of the straight slit. When the first section 320 and / or the second section 330 is a curved slit, the extending direction may be the tangent direction at any point position on the curve, such as the tangent direction at the end point position.

[0039] It should also be noted that the slit 31 can be a slit obtained by laser cutting. Compared with the mechanical cutting method, the width of the slit obtained by laser cutting is smaller.

[0040] According to the solution of the embodiment of the present disclosure, by making the extending directions of the two end segments of the slit different, the possibility of the slit being torn is effectively reduced, and the service life of the nipple is improved.

[0041] In one embodiment, each slit 31 is an arc-shaped slit, and the curvature of each arc-shaped slit is the same.

[0042] As Figures 2 - 4 shown, in the embodiment of the present disclosure, multiple slits 31 are all arc-shaped slits.

[0043] According to the solution of the embodiment of the present disclosure, the radian of the arc-shaped slit can effectively prevent the formation and expansion of cracks. The arc-shaped design avoids sharp stress concentration points. Even if tiny cracks appear, they are not likely to expand into large cracks, thus prolonging the service life of the nipple.

[0044] In one embodiment, the central angle of each slit 31 is between 90° and 270°. As a further preference, the central angle of each slit 31 is between 160° and 270°. Exemplarily, the central angle of each slit 31 can be different angles such as 160°, 180°, 220°, 250°, 270°, etc.

[0045] In the embodiment of the present disclosure, the curved design of the arc-shaped slit can effectively disperse the stress generated during sucking. When the arc-shaped slit is stressed, it can evenly distribute the stress along the arc, thereby reducing the risk of the liquid outlet 30 being torn. At the same time, a larger central angle means that the stress received by the arc-shaped slit during the opening and closing process is more uniform and gentle, which can increase the overall structural stability of the nipple and reduce fatigue tearing caused by repeated use. On the other hand, the arc-shaped slit design with a large central angle enables the nipple material to deform and recover more flexibly when subjected to the sucking force, enhancing the toughness of the material. This design can not only adapt to the sucking force of the baby but also maintain its shape and function after repeated use multiple times. Finally, the arc-shaped slit with a central angle between 90° and 270°, especially between 160° and 270°, can open and close evenly when stressed, rather than suddenly opening or closing. This smooth opening and closing action can not only prevent tearing but also further reduce the risk of damage to the nipple under high stress.

[0046] In one embodiment, the curvature at each point on the arc-shaped slit remains unchanged, and the curvature of each arc-shaped slit is the same.

[0047] As Figure 5As shown, in one embodiment, the first section 320 and the second section 330 of each slit 31 are both linear slits, and the included angle between the extending direction of the first section 320 and the extending direction of the second section 330 of the same slit 31 is between 45° and 135°.

[0048] In the embodiment of the present disclosure, the curvatures of the first section 320 and the second section 330 are both 0, that is, the first section 320 is a linear slit, and the second section 330 is also a linear slit. That is, the slit 31 is composed of two connected linear slits. The length of the line segment where the first section 320 is located is greater than the length of the line segment where the second section 330 is located. It should be understood that the first section 320 being a linear slit means that its orthographic projection on the plane of the opening end in the flared portion 20 is a straight line. When the area where the slit is provided at the top of the sucking portion 10 is a spherical surface or an arc surface, the first section 320 and the second section 330 can change with the shape of the surface of the area where the slit is provided at the top of the sucking portion 10.

[0049] According to the solution of the embodiment of the present disclosure, through the included angle between the straight lines, the stress generated during the sucking process is effectively dispersed. The design with the included angle between 45° and 135° avoids stress concentration, reduces the risk of tearing of the liquid outlet 30 of the nipple, and improves the service life of the nipple.

[0050] As Figure 6 shown, in one embodiment, each slit 31 further includes a third section 340.

[0051] The first section 320, the second section 330, and the third section 340 of the same slit 31 are all linear slits, and the intersection point of the first section 320 and the second section 330 is connected to the third section 340.

[0052] In the embodiment of the present disclosure, as Figure 6As shown, the first section 320, the second section 330, and the third section 340 in the same slit 31 are all linear slits. The third section 340 communicates with the intersection points of the first section 320 and the second section 330, that is, one end of the third section 340 communicates with the connection point (intersection point) of the first section 320 and the second section 330 to form the slit 31. As an implementation manner, the lengths of the second section 330 and the third section 340 are both less than the length of the first section 320. In another implementation manner, the lengths of the second section 330 and the third section 340 are the same. Specifically in implementation, the second section 330 and the third section 340 can be symmetrically connected to the first section 320, so that the shape of the formed slit 31 is approximately Y-shaped or arrow-shaped. An acute angle or an obtuse angle is formed between the second section 330 and the first section 320, and the included angle is between 45° and 135°. An acute angle or an obtuse angle is formed between the third section 340 and the first section 320, and the included angle is between 45° and 135°.

[0053] According to the solution of the embodiment of the present disclosure, the Y-shaped or arrow-shaped design disperses the stress to more directions and regions, reducing the single-point stress concentration. When stressed, each slit can support each other, providing better structural strength.

[0054] As Figure 7 shown, in one implementation manner, the included angle between the extending directions of the first section 320 and the second section 330 of the same slit 31 is 90°, and the first section 320 and the second section 330 form a T-shaped slit.

[0055] In the embodiment of the present disclosure, the slit 31 is a T-shaped slit, and the first section 320 and the second section 330 are perpendicular. As an implementation manner, the length of the first section 320 is greater than the length of the second section 330.

[0056] According to the solution of the embodiment of the present disclosure, the T-shaped structure disperses the stress to more directions, especially in the two main directions of vertical and horizontal. The T-shaped slit exhibits extremely high structural strength and stability when stressed. The combination of the vertical and horizontal sections enables the slit to maintain a good shape and function under forces in various directions.

[0057] In one implementation manner, multiple slits 31 are evenly arranged with a common-point end as the center.

[0058] In the embodiment of the present disclosure, the distances between corresponding positions of any two adjacent slits 31 are the same. When the liquid flows out from the evenly arranged slits, a uniform liquid distribution can be formed, avoiding the liquid impact in a single direction, improving the feeding comfort. The uniform flow path reduces the liquid turbulence and provides stable flow control. In addition, the slits are evenly arranged with a common-point end as the center, and the appearance is more symmetrical and beautiful, giving people a feeling of neatness and science.

[0059] In one embodiment, the liquid outlet 30 is disposed in the first region 11 at the top end of the sucking portion 10. The first region 11 is located in the central region of the top end of the sucking portion 10, and the wall thickness of the first region 11 is smaller than that of other regions.

[0060] In the embodiments of the present disclosure, the first region 11 can be understood as the region for opening the slit. Reducing the wall thickness of the first region 11 can avoid the blockage of the liquid outlet hole 11 due to the deformation of the sucking portion 10.

[0061] In one embodiment, the wall thickness of the first region 11 is 0.3 mm to 1.5 mm.

[0062] In the embodiments of the present disclosure, the wall thickness of the first region 11 can be selected as any value between 0.3 mm and 1.5 mm. For example, values such as 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5 mm, etc. are all acceptable.

[0063] In one embodiment, a convex rib 12 surrounding the first region 11 is formed by the inner wall of the sucking portion 10 bulging.

[0064] In the embodiments of the present disclosure, the top end of the sucking portion 10 further includes a second region. The second region surrounds the first region 11, and a convex rib 12 is formed by the inner wall of the second region bulging.

[0065] According to the solution of the embodiments of the present disclosure, the convex rib 12 surrounds the first region 11, improving the anti-deformation property, which can avoid the liquid outlet 30 being torn due to excessive deformation, and at the same time plays a supporting role for the first region 11.
