[0031] Example:

[0032] Reference Figure 1-7 This embodiment provides a nipple, which mainly includes a nipple head 1, a thickened portion 2 and a nipple body 3 connected in sequence. Figure 8 The boundary lines of the nipple head 1, the thickened portion 2 and the nipple body 3 are shown; obviously, the existing nipple shape is as follows Figure 1As shown, the nipple head 1 is designed to imitate the shape of a nipple, and the reinforcement part 7 is the main part for infants to suck and bite, so the reinforcement part 7 is generally arranged in an arc shape, and the upper part of the reinforcement part 7 should smoothly transition with the outer wall of the nipple head 1, and the lower part of the reinforcement part 7 should smoothly transition with the nipple body 3. Therefore, in this embodiment, for the convenience of description, the upper part of the reinforcement part 7 is called the first part, and the lower part of the reinforcement part 7 is called the second part.

[0033] Different from the prior art, in order to ensure the strength of the reinforcement part 7 and facilitate the cleaning of the pacifier, the wall thickness of the thickened part 2 gradually increases from top to bottom, and then remains unchanged or continues to increase. Due to the increase in the wall thickness of the reinforcement part 7, the strength here will inevitably increase, and the corresponding tensile and deformation resistance will be enhanced. In fact, infants and young children grow up quickly, and their oral capacity and depth will also increase accordingly. Therefore, the part that is most suitable for infants and young children to suck may be relatively forward at the beginning, and then gradually move backward. Therefore, this embodiment can adapt to the changes in the mouth shape of infants and young children during their growth period by gradually increasing first, then remaining unchanged or continuing to gradually increase. The maximum wall thickness is located at a certain position in the middle of the thickened part 2, and the wall thickness of the thickened part 2 begins to thin afterwards. If the child continues to grow, his sucking strength and bite strength will increase, and his bite position will be more backward, while the corresponding thickened part 2 becomes thinner, which is not conducive to adapting to the specific needs of his growth.

[0034] The above scheme corresponds to the following two situations:

[0035] (1)Reference Figure 8 , the wall thickness of the thickened part 2 increases first, and after reaching the maximum value in the middle of the thickened part 2, the wall thickness remains unchanged, and finally smoothly transitions with the nipple body 3; a tangent is drawn in the vertical direction with the maximum wall thickness of the thickened part 2, and the angle between the tangent and the first part (upper half) of the thickened part 2 depends on the increase in wall thickness; and the angle between the tangent and the lower half, since the wall thickness does not change, mainly depends on the slope of the nipple body 3 at the junction with the second part. The smaller the angle between the second part and the tangent at the maximum wall thickness of the thickened part 2, the easier it is for water to rush to the area of ​​the first part, thereby facilitating cleaning.

[0036] (2) The wall thickness of the thickened portion 2 is gradually increasing until it forms a smooth transition with the nipple body 3. This is similar to the situation in (1), but because the wall thickness is still increasing, it is equivalent to that the angle between the tangent direction at the maximum wall thickness of the thickened portion 2 and the inner wall of the second portion is reduced. When it decreases, it is easier for water to flow to the first portion for flushing when passing through the thickened portion 2. When cleaning, slightly tilting the nipple can allow the water to directly flush the first portion, thereby facilitating cleaning.

[0037] This embodiment does not adopt the design that the thickened portion 2 gradually thickens first and then gradually decreases in thickness. Specifically in this embodiment, if the above design is adopted, refer to Fig. 9 , the angle between the tangent direction at the maximum wall thickness of the thickened part 2 and the inner cavity of the second part will increase. Then, during flushing, after the water flows along the inner cavity of the nipple body 3 and then passes through the inner cavity of the thickened part 2, due to the large change in angle, the thickened part 2 forms a flushing blind area at the position of the first part, that is, after the water flows through the second part of the thickened part 2 (that is, after passing through the maximum wall thickness), most of the water flows directly to the top inner cavity of the nipple head 1, which will cause incomplete cleaning of the first part, making cleaning difficult, and it is easy to hide dirt and grime during long-term use; even if the nipple is tilted at this time, most of the water flow will impact the wall surface of the second part, making it difficult to completely flush the first part.

[0038] On the one hand, if Figure 8 As shown, the inner cavity of the thickened portion 2 takes the tangent in the vertical direction in the middle as the baseline, and the included angle formed by the baseline and the inner wall of the second portion is b, wherein it is preferably limited to 0<b≤30°, and the included angle between the inner wall of the nipple body 3 and the baseline here is actually about 30°~45°. If this angle is greater than this range, the flushing blind area formed after the water flows through the maximum wall thickness of the thickened portion 2 will be larger, which is not convenient for actual cleaning.

[0039] On the other hand, the baseline forms an angle a with the inner wall of the first part, where 10°≤a≤30°. The angle formed by the baseline and the inner wall of the first part corresponds to the actual angle of the flushing blind area. Obviously, if this angle is too large, it is not conducive to flushing after the water flows through the thickened part 2. Therefore, the angle b here is also specifically limited. In fact, the angle b is also a limit on the increase speed of the thickened part 2 in the first part. If the wall thickness increases too quickly, the angle b here will become larger.

[0040] The preferred values ​​proposed in this embodiment are: a = 20°, b = 10°. Under this set angle, the overall curvature of the transition between the first and second parts of the thickened portion 2 is also limited to a smaller range, so that the position of the first part is not likely to form a flushing blind area during flushing.

[0041] In this embodiment, the axis of the nipple head 1 preferably coincides with the axis of the nipple body 3. If they do not coincide, the angle formed by the thickened portion 2 and both the nipple head 1 and the nipple body 3 is not easy to control.

[0042] The preferred thickened portion in this embodiment has a wall thickness of one quarter to one half of the inner diameter of the thickened portion at its maximum wall thickness. The maximum wall thickness of the thickened portion is actually the optimal sucking and biting position designed for infants and young children. The wall thickness here is set to one quarter to one half of this inner diameter (diameter), so that the wall thickness here is sufficient, so that it is not easily damaged when infants and young children use it frequently, effectively increasing the service life.

[0043] In this embodiment, the distance between the maximum wall thickness of the thickened portion 2 and the top of the nipple head 1 is 8 mm to 22 mm, that is, the distance between the designed optimal sucking and biting position and the nipple head 1 is 8 mm to 22 mm.

[0044] In order to facilitate sucking by infants and young children, the nipple head, thickened portion and nipple body (i.e. the entire valve body) in this embodiment are made of a material with a Shore hardness of 10 to 20 degrees. Shore hardness is a common softness (hardness) standard. Within this range, the nipple has a better bite feeling.

[0045] In order to further enhance the anti-deformation ability of the thickened portion 2, the thickened portion 2 protrudes from the inner wall to form a reinforcement portion 7, which is evenly distributed along the circumference, and the number of the reinforcement portions 7 is 3 to 6. The reinforcement portion 7 is preferably a rib formed obliquely on the inner wall of the thickened portion 2, and the thickness of the reinforcement portion 7 is equal everywhere, so that the reinforcement portion 7 forms a three-dimensional spatial configuration along the inner wall of the thickened portion 2; the preferred inclination angle range of the reinforcement portion 7 is 30° to 60°. In order to leave enough milk passage in the inner cavity of the thickened portion 2, the inner diameter of the reinforcement portion 7 at the middle position of the thickened portion 2 is between one quarter and one half of the overall inner diameter of the thickened portion 2. In order to prevent the thickened portion 2 from being closed due to excessive deformation during sucking, an inclined fluid gap 7a is formed between two adjacent reinforcement portions 7 arranged at intervals. When the thickened portion 2 is deformed by force, the fluid gap 7a can prevent the entire channel from being closed due to excessive sucking and biting force to a certain extent. In addition, another significance of the spacing of the reinforcement part 7 is that when the infant starts to suck, the thickened part 2 is deformed. Before the reinforcement part 7 is completely close to the contact, the deformation resistance of the thickened part 2 changes little, that is, the normal sucking behavior of the infant generally does not trigger the deformation of the reinforcement part 7. Figure 4 At this time, only the fluid gap 7a becomes narrower, and in fact the reinforcement part 7 does not produce much deformation. Only when the infant exerts excessive force, the reinforcement part 7 plays a role in increasing resistance.

[0046] In order to balance the pressure in the bottle during use, the prior art can refer to Figure 6The nipple body 3 is provided with a ventilation balance structure 8, and a reduced diameter portion 9 is formed on the inner wall of the nipple body 3, and the inner diameter of the reduced diameter portion 9 is larger than the inner diameter of the middle part of the thickened portion 2; the height of the air gap at the bottom of the ventilation balance structure 8 is lower than the height of the bottom of the reduced diameter portion 9, so that a retention space 10 is formed between the ventilation balance structure 8, the inner wall of the nipple body 3 and the reduced diameter portion 9. During the cooling process of hot milk in the bottle, the air in the bottle shrinks due to the cold, and air can be introduced through the ventilation balance structure 8 to ensure the balance of air pressure in the bottle, and the air entering will form bubbles and rise to the position of the retention space 10 for buffering.

[0047] A liquid outlet is provided at the top of the inner cavity of the nipple head 1, and a reinforcement ring 6 is provided on the inner wall below the liquid outlet. The reinforcement ring 6 increases the wall thickness here, and the outer wall of the reinforcement ring 6 forms an arched structure. The reinforcement ring enables the nipple head 1 to form an arched structure that can stabilize its configuration, preventing the nipple head 1 from being compressed after entering the mouth and causing the volume of the inner cavity to be excessively reduced.

[0048] The nipple is provided with a common hanging groove 4 for easy taking; and a flange portion 5 is provided for facilitating the installation of the nipple on a feeding bottle.

[0049] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
