Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products technology, and in particular to a nipple assembly and a baby bottle. Background Technology

[0002] Baby bottles are devices used to feed infants during breastfeeding. They simulate the female breastfeeding organ to achieve the purpose of feeding. However, drinking milk directly from a bottle can easily lead to problems such as choking or swallowing a lot of air. Therefore, a straw and a nipple are usually used together to prevent choking. For example, Chinese patent CN219022353U discloses a nipple assembly. The nipple cavity of this assembly has a mounting part, and the straw connection part is interference-fitted with the mounting part. This nipple assembly has the following problems: both the nipple mounting part and the straw connection part are made of elastic silicone rubber, which can deform after assembly and is prone to falling off during use; moreover, the nipple limiting part is close to the sucking head, and the interference fit of the straw connection part during installation can cause the nipple flow hole to open too wide, leading to choking and posing a potential hazard. Utility Model Content

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

[0027] 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.

[0028] See Figures 1-6In one embodiment of this utility model, a nipple assembly includes a nipple 1 and a straw 2. The nipple 1 includes a nipple body 11, a protruding sucking head 13, and a cylindrical 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 communicates with a through hole on the top of the sucking head 13. The inner wall of the mounting portion 12 is provided with a groove 121 extending in a circumferential direction. On the side of the groove 121 away from the sucking head, at least one notch 122 is provided, which communicates with the groove 121.

[0029] The straw 2 includes a connecting part 221. At least one locking protrusion 222 extending in a circumferential direction is provided on the outer peripheral surface of the connecting part 221. The locking protrusion 222 cooperates with the locking groove 121. During assembly, the locking protrusion 222 passes through the notch 122 and rotates at a preset angle in a clockwise or counterclockwise direction to engage with the locking groove 121, thereby realizing the connection between the connecting part 221 and the mounting part 12.

[0030] The aforementioned nipple assembly features a latching protrusion 222 at the straw connector, which engages with a groove 121 on the inner wall of the cylindrical mounting portion 12 of the nipple. This allows for quick connection or disconnection of the connector and mounting portion 12 with a simple rotation. This design not only simplifies and speeds up assembly but also facilitates daily cleaning and maintenance, ensuring hygiene. Furthermore, the cooperation between the latching protrusion 222 and the groove 121 provides a more secure connection between the connector and mounting portion 12, reducing the risk of parts detaching or liquid leakage due to strong suction during use, thus improving product safety and reliability.

[0031] In one embodiment, the mounting portion 12 is further provided with an anti-slip structure to prevent the latching protrusion 222 from slipping off the notch 122. As an example, the notch 122 is designed to be wider at the front and narrower at the back along the direction of sliding into the slot 121, and the width L2 of the narrowest part is smaller than the width L1 of the latching protrusion 222, thus forming the anti-slip structure. Through the front-wide-narrow-backward design of the notch 122 and the setting that the width of the narrowest part is smaller than the width of the latching protrusion 222, it is ensured that once the latching protrusion 222 is engaged with the slot 121, even under a large external force, the latching protrusion 222 is not easily slipped off the notch 122. This anti-slip structure greatly improves the stability of the connecting portion 221, reduces accidental detachment during use, and ensures a smooth and safe feeding process.

[0032] In one embodiment, there are two slots 121 located in the diametrical direction of the mounting portion 12; and two protrusions 222 located in the diametrical direction of the plug portion. This further increases the stability of the connection between the connector and the mounting portion 12.

[0033] In one embodiment, the sidewall 223 of the latching protrusion 222 away from the sucking head 13 is inclined, and the groove wall of the latching groove 121 away from the sucking head 13 is flat. When rotated to a preset angle, the groove wall of the latching groove 121 away from the sucking head 13 is in close contact with the sidewall of the latching protrusion 222 away from the sucking head 13. Alternatively, the groove wall of the latching groove 121 away from the sucking head 13 is inclined, and the sidewall 223 of the latching protrusion 222 away from the sucking head 13 is flat. The inclined design has a self-locking effect. When the latching protrusion 222 rotates to close contact with the inclined surface of the groove 121, a self-locking state is generated due to the wedging effect of the inclined surface. This state effectively prevents the connection part 221 from loosening or falling off due to vibration or strong infant sucking force, enhancing safety during use.

[0034] In one embodiment, the straw includes a body 21 and a connector 22. The connector 22 is made of a rigid material (such as silicone, plastic, or metal with a hardness of 50 or higher), and its lower part is connected to the upper end of the straw body 21, while its upper part has a connecting portion 221. The connector is made of a rigid material, such as silicone, plastic, or metal with a hardness of 50 or higher, which makes the connection more secure.

[0035] In one embodiment, the lower part of the connector 22 has an inner core 224, and the upper end of the straw body 21 has a covering part 211. The covering part 211 is integrally formed with the inner core 224 and tightly wraps around the inner core 224. In this structure, the straw body 21 and the connector 22 are manufactured using an integrated overmolding process. The connector 22 is manufactured first, and then placed in a mold and formed together with the straw body 21 in one step. Preferably, the outer surface of the covering part 211 has a shape that is thicker at both ends and thinner in the middle for easy gripping and easy assembly and disassembly. The inner core 224 is cylindrical or approximately conical with a thicker top and thinner bottom. This design makes the connection between the straw body 21 and the connector 22 tighter, and also increases the flexibility and durability of the straw 2.

[0036] In one embodiment, the straw 2 further includes a gravity ball 23 connected to the lower end of the straw body 21. The gravity ball 23 ensures that the lower end of the straw 2 remains submerged in the liquid regardless of the bottle's tilt angle, thus ensuring that the baby can smoothly drink milk in various positions. The gravity ball 23 has a stepped design to prevent the flow orifice from being blocked by the bottle body.

[0037] In one embodiment, a baby bottle is provided, including a bottle body and the nipple assembly described in the above embodiments.

[0038] 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.
