It should be understood that the use of these directional terms should not limit the scope of protection claimed by this utility model.

[0024] 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.

[0025] See Figures 1-4 One embodiment of the present invention includes a nipple assembly comprising a nipple 1 and a straw 2. The nipple 1 includes a nipple body 11, a protruding sucking head 13, and a mounting portion 12 located within the nipple body 11. The nipple body 11 has a cavity for storing liquid. The sucking head 13 has a channel for liquid to pass through, one end of which communicates with the cavity of the nipple body 11, and the other end of which communicates with a through hole on the top of the sucking head 13. The mounting portion 12 is cylindrical.

[0026] The straw 2 includes a straw body 21 made of a soft material and a connector 22 made of a hard material. The lower part of the connector 22 is integrally formed with the upper end of the straw body 21, and the upper part is provided with a cylindrical connecting part 221. The connecting part 221 is detachably connected to the mounting part 12, and the central hole of the connector 22 communicates with the central hole of the straw body 21. The terms "hard material" and "soft material" are relative concepts, indicating only that the hardness of the connector 22 is higher than that of the straw body 21. In one embodiment, the connector 22 may be made of silicone, plastic (such as PP plastic), or metal with a hardness of 50 degrees or higher, while the straw body 21 may be made of silicone material with a hardness of less than 50 degrees.

[0027] The aforementioned nipple assembly, with the straw body 21 and connector 22 made of different materials (soft and hard), ensures both the softness of the straw, making it easy to suck the liquid out of the bottle, and the rigidity of the connector 22, making the connection between the straw 2 and the nipple 1 more secure, preventing loosening and liquid leakage, and extending the service life.

[0028] In one embodiment, the inner wall of the mounting portion 12 is provided with a convex ring 121 extending in the circumferential direction, and the outer wall of the connecting portion 221 is provided with a groove 221a extending in the circumferential direction. The mounting portion 12 is inserted into the mounting portion 12, and the convex ring 121 is engaged in the groove 221a. The cooperative design of the convex ring 121 and the groove 221a ensures a stable connection of the nipple assembly during use, preventing it from easily loosening even under repeated sucking or high-pressure conditions. This design ensures the reliability of the straw 2 and the nipple body 11, preventing leakage or loose connections. Furthermore, the plug-in connection allows the straw assembly to be easily disassembled after daily use, facilitating cleaning and replacement, effectively improving the hygiene and lifespan of the nipple assembly.

[0029] In one embodiment, the lower part of the connector 22 has an inner core 223, and the upper end of the straw body 21 has a covering part 211. The covering part 211 and the inner core 223 are integrally formed and tightly cover the inner core 223. The integral forming of the covering part 211 and the inner core 223 effectively prevents leakage caused by gaps between the straw body 21 and the inner core 223. This structural design greatly improves the sealing effect of the entire nipple assembly, ensuring that liquid only enters the baby's mouth through the central hole and does not cause accidental leakage. In one embodiment, the covering part 211 and the inner core 223 can be integrally injection molded.

[0030] In one embodiment, the connector 22 further includes a grip 222, which is an axially extending cylindrical structure. The upper end of the grip 222 is connected to the connector 221, and the lower end is connected to the inner core 223. The grip 222 is designed to provide a convenient hand position for the user, making it easier to attach and detach the straw 2, especially in situations requiring repeated disassembly and cleaning. The presence of the grip 222 effectively improves the convenience and efficiency of operation. The cylindrical structure of the grip 222 allows the user to easily apply uniform force, avoiding damage to components or accidental leakage due to improper force.

[0031] In one embodiment, the outer surface of the grip 222 gradually tapers inward from top to bottom, forming a conical curve structure. This structure, with its gradually decreasing outer diameter, provides a more easily gripped area, reducing the need for hand strength when attaching or detaching the straw 2. Furthermore, the conical curve structure of the outer surface of the grip 222 allows it to fit more snugly against the fingers during use, improving ease of operation.

[0032] In one embodiment, the outer surface of the covering portion 211 gradually tapers inward from top to bottom, forming a conical curve structure, and the outer diameter of the upper end of the covering portion 211 is consistent with the outer diameter of the lower end of the grip portion 222. The outer surface of the covering portion 211 has a conical curve structure that is thicker at the top and thinner at the bottom. This structure can provide additional gripping positions while reducing liquid residue when flowing along the outside of the covering portion 211.

[0033] In one embodiment, the central hole of the connector 22 includes a liquid storage section 224, the inner diameter of which is at least twice the inner diameter of the central hole of the straw body 21. The presence of the liquid storage section 224 provides a buffer area for the straw 2, ensuring a stable supply of liquid during suction and preventing splashing when the suction force changes. Further, the liquid storage section 224 includes a first section hole 224a corresponding to the position of the connector 22 and a second section hole 224b corresponding to the position of the grip 222. The first section hole 224a is a hole of equal diameter, and the inner diameter of the second section hole 224b expands from bottom to top. The combined design of the first section hole 224a and the second section hole 224b provides better control during liquid flow. The first section hole 224a, with its equal diameter design, ensures the stability of liquid flow, while the second section hole 224b, with its expanded structure, effectively reduces the risk of liquid splashing, ensuring that the liquid flow rate remains stable under different suction conditions.

[0034] In one embodiment, a baby bottle is provided, including a bottle body and the nipple assembly described in the above embodiments.

[0035] 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.
