Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, in particular to a pacifier. Background Art

[0002] As a tool installed on a feeding bottle to assist infants in sucking milk, the pacifier's main function is to simulate the sucking experience of breast milk and help infants obtain nutrition. Due to the dietary needs of infants, the pacifier has become an important part of the feeding bottle.

[0003] Pacifiers are typically made of silicone, which has a certain degree of elasticity. This flexibility allows the pacifier to adapt to the child's sucking action during use, but it also brings issues with its lifespan. When elastic materials are repeatedly subjected to stress and deformation, their molecular structure gradually changes, leading to a decline in performance.

[0004] Every time a pacifier is used, it deforms as the child sucks. Repeated deformation gradually accumulates and damages the pacifier structure. Inelastic deformation, which exceeds the material's recoverable range, is particularly damaging.

[0005] Inelastic deformation is most likely to occur at the junction of the nipple head and body. This area is a transitional zone in the nipple structure, where stress is relatively concentrated. Once inelastic deformation occurs, this area may experience localized contraction, distortion, or deformation, thereby blocking the flow of milk. This prevents milk from flowing smoothly through the nipple, resulting in improper use and the end of its service life.

[0006] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0008] A nipple includes a nipple head and a nipple body, wherein the nipple head and the nipple body are connected in a smooth arc-shaped transition, and the wall thickness of the nipple body gradually increases from the end connected to the nipple head to the end of the nipple body away from the nipple head, so that the wall thickness of the nipple body is greater than the wall thickness of the nipple head.

[0009] As a further solution of the present invention: the nipple body includes a connecting portion and a base, the nipple head, the connecting portion and the base are connected in sequence from top to bottom, and the nipple head and the base are connected through the connecting portion in a smooth arc-shaped transition.

[0010] As a further solution of the present invention: the wall thickness of the connecting portion gradually increases from the end connected to the nipple to the end of the base away from the connecting portion.

[0011] As a further solution of the present invention: the wall thickness of the base gradually increases from the end connected to the connecting portion to the end of the base away from the connecting portion, and the wall thickness of the connecting portion is between the wall thickness of the nipple body and the wall thickness of the base.

[0012] As a further solution of the present invention: the wall thickness of the base gradually increases from the end connected to the connecting portion to the end of the base away from the connecting portion, and the wall thickness of the connecting portion is substantially the same as the wall thickness of the nipple.

[0013] As a further solution of the present invention: a reinforcement structure is provided inside the connecting portion and along its circumference.

[0014] As a further solution of the present invention: the reinforcement structure includes a first reinforcement ring located at the junction of the connecting portion and the nipple head.

[0015] As a further solution of the present invention: the reinforcement structure also includes a second reinforcement ring located at the junction of the connecting portion and the base.

[0016] As a further solution of the present invention: the reinforcement structure also includes a third reinforcement ring located between the first reinforcement ring and the second reinforcement ring.

[0017] As a further solution of the present invention: the first reinforcement ring, the second reinforcement ring and the third reinforcement ring are used to form a gradually inward-contracting stepped structure on the inner side of the connecting portion from bottom to top.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1) The nipple head and the nipple body are connected in a smooth arc-shaped transition. This design can disperse the stress at the connection and avoid rapid inelastic deformation caused by stress concentration;

[0020] 2) The wall thickness of the nipple body gradually increases from the end connected to the nipple head to the end away from the nipple head, making the nipple body have better pressure resistance when bearing the sucking pressure. The thicker nipple body wall can provide stronger support and reduce the degree of deformation of the nipple body, thereby reducing the probability of damage caused by deformation and effectively extending the overall service life of the nipple;

[0021] 3) Reducing the deformation of the nipple allows the milk channel to remain stable and not easily blocked, ensuring that the milk can flow out smoothly, allowing the baby to suck normally, thereby enhancing the stability of the nipple and effectively improving the safety and comfort of use;

[0022] 4) The design principle of the first, second, and third reinforcement rings is to form multi-point support and reinforcement by adding reinforcement rings at key locations of the connection, thereby more comprehensively dispersing and bearing stress from different directions and locations, avoiding excessive concentration of stress at a specific location, and effectively reducing inelastic deformation of the connection during use;

[0023] 5) The stepped structure allows stress to be gradually dispersed and weakened along different reinforcement rings during transmission, reducing the risk of local stress concentration and inelastic deformation; at the same time, the inward-constricted shape also helps guide the flow of milk, making it smoother and more stable.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-3 In an embodiment of the utility model, a nipple includes a nipple head 1 and a nipple body 2, and the nipple head 1 and the nipple body 2 are connected in a smooth arc-shaped transition. The wall thickness of the nipple body 2 gradually increases from the end connected to the nipple head 1 to the end of the nipple body 2 away from the nipple head 1, so that the wall thickness of the nipple body 2 is greater than the wall thickness of the nipple head 1.

[0033] In the technical solution of the present utility model, the design principle of the pacifier is to reduce the inelastic deformation of the pacifier during use by optimizing the connection structure of the pacifier head 1 and the pacifier body 2 and adjusting the wall thickness distribution of the pacifier body 2, thereby extending the service life of the pacifier; specifically, the pacifier head 1 and the pacifier body 2 are connected in a smooth arc-shaped transition. This design can disperse the stress at the connection and avoid rapid inelastic deformation caused by stress concentration. The wall thickness of the pacifier body 2 gradually increases from the end connected to the pacifier head 1 to the end of the pacifier body 2 away from the pacifier head 1, so that the pacifier body 2 has better pressure resistance when subjected to sucking pressure. The thicker wall thickness of the pacifier body 2 can provide stronger support, reduce the degree of deformation of the pacifier body 2, thereby reducing the probability of damage caused by deformation, effectively extending the overall service life of the pacifier, and at the same time, reducing the deformation of the pacifier allows the milk channel to remain stable and not easily blocked, ensuring that the milk can flow out smoothly, facilitating normal sucking for the child, thereby enhancing the stability of the pacifier, and effectively improving the safety and comfort of use.

[0034] In the embodiment of the present invention, the nipple body 2 includes a connecting portion 3 and a base 4. The nipple head 1, the connecting portion 3 and the base 4 are connected in sequence from top to bottom. The nipple head 1 and the base 4 are connected through the connecting portion 3 in a smooth arc-shaped transition.

[0035] It can be understood that the nipple 1, the connecting part 3 and the base 4 are an integrally connected structure. The connecting part 3 serves as the transition area between the nipple 1 and the base 4. It itself can be designed as a smooth arc-shaped transition structure, and the smooth arc-shaped transition between the nipple 1 and the base 4 is achieved through the connecting part 3. This structural design can more effectively disperse the stress during the sucking process, make the force more uniform during the transmission process, and reduce the inelastic deformation caused by local stress concentration.

[0036] More specifically, the nipple 1, the connecting portion 3 and the base 4 are provided with a cavity in common. A channel is provided at the top of the nipple 1 and an opening is provided at the bottom of the base 4. The channel, the cavity and the opening are connected in sequence, thereby forming a complete milk flow path. This design ensures that the milk can smoothly flow from the bottle through the nipple to the baby's mouth, avoiding blockage and residue of the milk during the flow process.

[0037] In one implementation of the embodiment of the present invention, the wall thickness of the connecting portion 3 gradually increases from the end connected to the nipple 1 to the end of the base 4 away from the connecting portion 3 .

[0038] By gradually increasing the wall thickness from the end where the connecting part 3 is connected to the nipple 1 to the end where the base 4 is away from the connecting part 3, the structure of the nipple forms a gradual transition from thin to thick. This design can better adapt to the pressure changes generated during the sucking process. The thinner end near the nipple 1 can maintain a certain softness and flexibility, making it easier for the child to suck. The gradually increasing wall thickness (i.e., the connecting part 3 and the base 4) can provide stronger support and pressure resistance, effectively dispersing and withstanding the force generated during sucking, thereby enabling the nipple to withstand greater sucking force and external pressure, reducing the possibility of deformation and damage.

[0039] In another embodiment of the present invention, the wall thickness of the base 4 gradually increases from the end connected to the connecting part 3 to the end of the base 4 away from the connecting part 3, and the wall thickness of the connecting part 3 is between the wall thickness of the nipple body 2 and the wall thickness of the base 4.

[0040] The wall thickness of the base 4 gradually increases from the end connected to the connecting part 3 to the end of the base 4 away from the connecting part 3. This design enables the base 4 to withstand greater pressure and friction at the end away from the connecting part 3, thereby enhancing the stability and durability of the base 4; at the same time, the wall thickness of the connecting part 3 is between the nipple body 2 and the base 4, forming a transition area, which can balance the stress distribution between the nipple head 1, the connecting part 3 and the base 4, making the force transmission more uniform and reducing local stress concentration. For example, when a child sucks vigorously, the stress can be evenly transmitted to other parts through the connecting part 3, thereby effectively reducing local excessive deformation.

[0041] In another embodiment of the present invention, the wall thickness of the base 4 gradually increases from the end connected to the connecting portion 3 to the end of the base 4 away from the connecting portion 3, and the wall thickness of the connecting portion 3 is substantially the same as the wall thickness of the nipple 1.

[0042] The wall thickness of the base 4 gradually increases from the end connected to the connecting part 3 to the end of the base 4 away from the connecting part 3, which can enhance the structural strength and stability of the base 4 and reduce the possibility of inelastic deformation in this part; the wall thickness of the connecting part 3 is roughly the same as the wall thickness of the nipple 1. This design can ensure that during the sucking process, the softness and elasticity of the nipple 1 and the connecting part 3 are similar, making the sucking action more natural and smooth, and at the same time making the stress transfer in the two parts more uniform, avoiding stress concentration and uneven deformation caused by excessive difference in wall thickness, thereby reducing the risk of inelastic deformation.

[0043] In the embodiment of the present invention, a reinforcement structure is provided inside the connecting portion 3 and along its circumference, specifically:

[0044] The reinforcement structure includes a first reinforcement ring 5 located at the junction of the connecting portion 3 and the nipple head 1;

[0045] The reinforcement structure further includes a second reinforcement ring 6 located at the junction of the connecting portion 3 and the base 4 .

[0046] The reinforcement structure further includes a third reinforcement ring 7 located between the first reinforcement ring 5 and the second reinforcement ring 6 .

[0047] Since the junction between the connecting part 3 and the nipple head 1 is an area of ​​stress concentration and is prone to inelastic deformation, the first reinforcement ring 5 can provide additional support to limit excessive deformation of this part; through the design of the first reinforcement ring 5, the second reinforcement ring 6 and the third reinforcement ring 7, the design principle is to add reinforcement rings at key positions of the connecting part 3 to form multi-point support and reinforcement, so as to more comprehensively disperse and withstand stress from different directions and parts, avoid excessive concentration of stress at a specific position, and effectively reduce the inelastic deformation of the connecting part 3 during use, thereby greatly extending the overall service life of the nipple.

[0048] In the embodiment of the present invention, the first reinforcement ring 5 , the second reinforcement ring 6 and the third reinforcement ring 7 are used to form a gradually inward-contracting stepped structure on the inner side of the connecting portion 3 from bottom to top.

[0049] The stepped structure allows stress to be gradually dispersed and weakened along different reinforcement rings during the transmission process, reducing the risk of local stress concentration and inelastic deformation. For example, when a child sucks vigorously, the pressure generated can be gradually released along the stepped structure, reducing excessive impact on specific parts of the connection part 3; at the same time, the inward-contracted shape also helps to guide the flow of milk, making it smoother and more stable.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
