Description

Technical Field

[0001] The utility model relates to mother and baby products, in particular to a nipple shield, a nipple and a feeding bottle. Background Art

[0002] Breastfeeding is a natural way to feed infants and young children. During breastfeeding, the infant holds the mother's nipple in the mouth and squeezes the milk from the mother's breast by wriggling the tongue. That is to say, during the process of the mother feeding the infant and young child, the nipple will be stressed, which is likely to cause nipple chapping, bringing discomfort and pain to the mother, and even causing nipple injury in severe cases. For this reason, the nipple shield is invented. For example, a nipple shield is disclosed in a Chinese utility model patent with the authorization announcement number CN219230782U, which includes a nipple and a protective cover. The nipple is arranged at the top of the protective cover and is communicated with the inside of the protective cover. The top of the nipple is provided with a milk outlet. The protective cover is conical. The nipple is inclined to one side and is arranged at an acute angle with the central axis of the bottom edge of the protective cover. When in use, the mother attaches the nipple shield to the breast and covers the nipple. The infant and young child sucks milk by holding the nipple of the nipple shield in the mouth. In this way, the nipple shield isolates the breast and the infant's oral cavity, avoiding the above problems. The existing nipple shield uses the tilted nipple design scheme, expecting the mother to conveniently adjust the suitable angle for convenient feeding. However, the tilting direction and tilting angle of the nipple of the existing nipple shield are both fixed. When the mother attaches the existing nipple shield to the breast, she needs to pay special attention to the orientation of the nipple, and during the feeding process, she needs to pay special attention to the sucking posture of the infant and young child.

[0003] In addition, feeding bottles are commonly used in the process of feeding infants and young children. They are used to hold fluids such as breast milk, prepared milk powder, and water for infants and young children to consume by holding the nipple of the feeding bottle in the mouth. Different from children and adults, infants and young children have poor self-control ability. When they hold the nipple of the feeding bottle in the mouth, their heads will shake relative to the hands of the feeders such as parents. Although the nipples of existing feeding bottles are made of deformable materials such as silica gel, the structure of the nipples of existing feeding bottles causes them unable to swing flexibly. Once the shaking amplitude of the infant's head relative to the hands of the feeders such as parents is large, it will inevitably cause relative friction between the nipple and the infant's oral cavity. In this way, not only is the nipple unfriendly to the inner wall of the infant's oral cavity or the gum, but also it is easy for the nipple to fall off from the infant's mouth, resulting in the fluid dripping onto the infant's face, neck, etc. Summary of the Utility Model

[0004] An object of the utility model is to provide a nipple shield, a nipple and a feeding bottle, wherein when the entrance part of the nipple shield is horizontally pulled, the shoulder part of the nipple shield deforms, so that when the nipple shield is adsorbed on the breast, the entrance part is allowed to swing horizontally to make the shape of the nipple shield adapt to the mother's posture of feeding the infant and young child.

[0005] An object of the present utility model is to provide a nipple shield, a nipple and a feeding bottle, wherein the shoulder extends between the bottom side of the inlet portion and the top side of the fitting base portion of the nipple shield, and the included angle α formed between the extending direction of the shoulder and the extending direction of the fitting base portion is an obtuse angle. When the mother wears the nipple shield, the nipple shield allows a negative pressure space to be formed between the breast, the fitting base portion and the shoulder, so that the nipple shield can be reliably adsorbed on the breast. Thus, when the infant horizontally pulls the inlet portion, the shoulder is easily deformed, and the orientation and angle of the inlet portion are adaptively adjusted to the state of the mother's posture of feeding the infant, while preventing the nipple shield from falling off the breast.

[0006] An object of the present utility model is to provide a nipple shield, a nipple and a feeding bottle, wherein the shoulder extends between the bottom side of the inlet portion and the top side of the fitting base portion, so that during the process of the mother feeding the infant, even if the mother adjusts the feeding posture, the orientation and angle of the inlet portion will automatically change with the change of the mother's feeding posture, so that the orientation and angle of the inlet portion are adaptively adjusted to the state of the mother's posture of feeding the infant.

[0007] An object of the present utility model is to provide a nipple shield, a nipple and a feeding bottle, wherein the shoulder extends obliquely between the bottom side of the inlet portion and the top side of the fitting base portion, so that the shape of the cavity of the nipple shield matches the shape of the breast, which is beneficial for the mother to stably wear the nipple shield and ensure wearing comfort.

[0008] An object of the present utility model is to provide a nipple shield, a nipple and a feeding bottle, wherein the nipple shield is provided with at least one one-way valve in the fitting base portion for discharging the air in the negative pressure space so that the nipple shield can be reliably adsorbed on the breast.

[0009] An object of the present utility model is to provide a nipple shield, a nipple and a feeding bottle, wherein the one-way valve is received in the exhaust passage of the fitting base portion to prevent the one-way valve from protruding. Thus, during the process of the mother feeding the infant, the fitting base portion can prevent the one-way valve from being misoperated, so that the nipple shield can be reliably adsorbed on the breast.

[0010] An object of the present utility model is to provide a nipple protector, a nipple, and a feeding bottle. When a feeder such as a parent feeds an infant through the feeding bottle, the orientation and angle of the nipple portion of the nipple will be adaptively adjusted as the head of the infant swings, so as to reduce or even avoid the movement of the nipple portion relative to the mouth of the infant, thereby not only being able to protect the inner wall of the infant's oral cavity, but also being able to avoid the problem that the nipple portion falls off from the infant's oral cavity.

[0011] An object of the present utility model is to provide a nipple protector, a nipple, and a feeding bottle. A connecting portion is provided between the nipple portion and the mounting portion for mounting the nipple at the bottle mouth of the bottle body. When the infant holds the nipple portion in the mouth and swings the head, the connecting portion can be laterally pulled by the nipple portion and deformed, so that the orientation and angle of the nipple portion are adaptively adjusted. Thus, when the hands of a feeder such as a parent remain stationary and the head of the infant shakes, the possibility of the nipple portion moving relative to the mouth of the infant is reduced or even avoided.

[0012] An object of the present utility model is to provide a nipple protector, a nipple, and a feeding bottle. The thickness dimension of the connecting portion is smaller than the thickness dimension of the portion of the nipple portion adjacent to the connecting portion, and the thickness dimension of the connecting portion is smaller than the thickness dimension of the portion of the mounting portion adjacent to the connecting portion. In this way, the connecting portion is easily deformed to flexibly adjust the orientation and angle of the nipple portion. At the same time, the connecting portion can have a small restoring force, so that the infant is not easily aware of the reaction force provided by the nipple portion to the inner wall of the oral cavity. Thus, after the orientation and angle of the nipple portion are adaptively adjusted, the infant is insensitive, so as to improve the comfort of the infant when using the feeding bottle to eat.

[0013] An object of the present utility model is to provide a nipple protector, a nipple, and a feeding bottle. The feeding bottle presses a part of the mounting portion of the nipple against the end face at the bottle mouth of the bottle body through a gland. In this way, on the one hand, the gland can reliably mount the nipple on the bottle body, and on the other hand, the gland and the bottle mouth of the bottle body can slightly press and deform a part of the mounting portion to prevent a gap from being generated between the mounting portion and the end face at the bottle mouth of the bottle body, thereby avoiding liquid leakage at the mounting position of the mounting portion and the bottle body.

[0014] An object of the present utility model is to provide a nipple protector, a nipple, and a feeding bottle. The mounting portion of the nipple has a groove, and a part of the gland extends into the groove of the mounting portion.

[0069] Before detailing any embodiment of the present utility model, it should be understood that in its application, the present utility model is not limited to the construction and arrangement details of the components described in the following description or illustrated in the following drawings. The present utility model is capable of other embodiments and can be practiced or carried out in various ways. Additionally, it should be understood that the wording and terminology used herein are for the purpose of description and should not be regarded as restrictive. As used herein, the terms "comprising", "comprises" or "having" and their variants are intended to cover the items listed hereinafter and their equivalents as well as additional items. Unless otherwise specified or restricted, the terms "mounted", "connected", "supported" and "coupled" and their variants are used broadly and cover direct mounting and indirect mounting, connection, support and coupling. Further, "connected" and "coupled" are not limited to physical or mechanical connection or coupling.

[0070] And, on the one hand, in the disclosure of the present utility model, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present utility model; on the other hand, the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as limiting the quantity.

[0071] Referring to the attached drawings of the specification of the present utility model Figures 1 to 9 , a nipple protection cover according to a preferred embodiment of the present utility model will be disclosed and described hereinafter, wherein the nipple protection cover includes an inlet portion 10, a deformable shoulder portion 20 and a fitting base portion 30 and has a cavity 40. The inlet portion 10, the shoulder portion 20 and the fitting base portion 30 are an integral structure, and the inlet portion 10, the shoulder portion 20 and the fitting base portion 30 together form the cavity 40.

[0072] Specifically, the inlet portion 10, the shoulder portion 20, and the fitting base portion 30 are integrally made of an elastic material. For example, a silicone material can be used to integrally make the inlet portion 10, the shoulder portion 20, and the fitting base portion 30. The shoulder portion 20 integrally extends outward from the bottom side of the inlet portion 10, and the fitting base portion 30 integrally extends downward from the outer side of the shoulder portion 20. The inlet portion 10, the shoulder portion 20, and the fitting base portion 30 define the cavity 40, and the fitting base portion 30 forms an opening 41 of the cavity 40. The inlet portion 10 has a drainage channel 11, and the drainage channel 11 communicates with the cavity 40. An included angle α formed between the extending direction of the shoulder portion 20 and the extending direction of the fitting base portion 30 is an obtuse angle, so that the inner wall of the nipple shield for defining the cavity 40 forms a concave surface. Refer to the attached Figure 4 .

[0073] When the mother wears the nipple shield, the nipple is received in the cavity 40 of the nipple shield and surrounded by the inlet portion 10. The areola portion abuts against the connection position of the inlet portion 10 and the shoulder portion 20, and the breast closes the opening 41 of the nipple shield. In this way, the nipple shield allows a negative pressure space 1000 to be formed between the breast, the shoulder portion 20, and the fitting base portion 30 for reliably adsorbing the nipple shield to the mother's breast. When the inlet portion 10 is pulled laterally, the inlet portion 10 can deform the shoulder portion 20 and allow the inlet portion 10 to swing laterally, thereby adjusting the orientation and angle of the inlet portion 10, where "laterally" refers to a direction perpendicular to the extending direction of the inlet portion 10. Preferably, the shape and size of the inlet portion 10 are consistent with those of the nipple so that the inlet portion 10 simulates the nipple for soothing the infant.

[0074] That is to say, in this specific example of the nipple shield of the present invention, since the inner wall of the nipple shield for defining the cavity 40 forms a concave surface, when the mother wears the nipple shield, the nipple shield allows the negative pressure space 1000 to be formed between the breast, the shoulder portion 20, and the fitting base portion 30 for reliably adsorbing the nipple shield to the breast.

[0075] When an infant sucks milk with the nipple shield's inlet portion 10 in its mouth, on the one hand, the milk discharged from the mother's breast reaches the infant's oral cavity through the liquid discharge channel 11 of the inlet portion 10 and is swallowed by the infant. On the other hand, when the mother adjusts the feeding posture, the infant horizontally pulls the inlet portion 10, and the inlet portion 10 pulls the shoulder portion 20 to deform the shoulder portion 20, allowing the orientation and angle of the inlet portion 10 to adaptively adjust to the state of the mother's feeding posture. On the other hand, during the process of the mother feeding the infant, even if the mother adjusts the feeding posture, the orientation and angle of the inlet portion 10 will automatically change with the change of the mother's feeding posture, so that the orientation and angle of the inlet portion 10 adaptively adjust to the state of the mother's feeding posture. That is to say, during the process of the mother feeding the infant, the mother does not need to take out the inlet portion 10 of the nipple shield from the infant's mouth to adjust the feeding posture, and during the process of the mother adjusting the feeding posture, the orientation and angle of the inlet portion 10 automatically change and adaptively adjust to the state of the mother's feeding posture. It can be understood that when the mother wears the nipple shield, since the areola portion abuts against the connection position of the inlet portion 10 and the shoulder portion 20, the milk discharged from the mother's breast will not enter the negative pressure space 1000, which is beneficial to ensuring that the nipple shield is reliably adsorbed on the breast.

[0076] In other words, when the mother wears the nipple shield, she does not need to pay attention to the orientation of the inlet portion 10. When the infant sucks the inlet portion 10 and horizontally pulls the inlet portion 10, both the orientation and angle of the inlet portion 10 can adaptively adjust to the state of the mother's feeding posture, which is crucial for the mother to conveniently feed the infant with the help of the nipple shield and for the mother to comfortably feed the infant with the help of the nipple shield.

[0077] In an embodiment of the nipple shield of the present utility model, the nipple shield further includes at least one mouth reinforcing rib 50, the mouth reinforcing rib 50 is integrally formed on the inlet portion 10, and the mouth reinforcing rib 50 is located in the cavity 40. The mouth reinforcing rib 50 is used to enhance the structural strength of the inlet portion 10, so that the inlet portion 10 maintains the shape of the nipple and is not easily damaged, thereby enabling the inlet portion 10 to simulate the nipple and extending the service life of the nipple shield. In this specific example of the nipple shield of the present utility model, refer to the attached Figures 3 to 6, the mouth reinforcing rib 50 is annular, and the two mouth reinforcing ribs 50 are arranged at intervals. Optionally, in other examples of the nipple protector of the present invention, the mouth reinforcing rib 50 extends spirally along the extending direction of the inlet portion 10. In this way, the mouth reinforcing rib 50 can prevent the opposite sides of the inner wall of the inlet portion 10 from fitting together, thereby preventing the adhesion of the inner wall of the inlet portion 10.

[0078] In a specific example of the nipple protector of the present invention, refer to the attached Figures 3 to 6 , the shoulder portion 20 extends integrally downward from the bottom side of the inlet portion 10, so that the shoulder portion 20 extends obliquely between the inlet portion 10 and the fitting base portion 30, wherein the fitting base portion 30 extends integrally outward from the outer side of the shoulder portion 20, so that the fitting base portion 30 extends obliquely from the shoulder portion 20. That is to say, in this specific example of the nipple protector of the present invention, the shoulder portion 20 extends integrally outward and downward from the bottom side of the inlet portion 10, so that the shoulder portion 20 is conical, and the fitting base portion 30 extends integrally downward and outward from the outer side of the shoulder portion 20, so that the fitting base portion 30 is conical. In this way, the shape of the cavity 40 of the nipple protector can match the shape of the breast, so that the nipple protector can be stably worn by the mother and ensure wearing comfort.

[0079] In an example of the nipple protector of the present invention, the thickness dimension of the shoulder portion 20 is smaller than the thickness dimension of the portion of the inlet portion 10 adjacent to the shoulder portion 20, and the thickness dimension of the shoulder portion 20 is smaller than the thickness dimension of the portion of the fitting base portion 30 adjacent to the shoulder portion 20. That is to say, compared with the portion of the inlet portion 10 adjacent to the shoulder portion 20 and the portion of the fitting base portion 30 adjacent to the shoulder portion 20, the shoulder portion 20 is thinner. In this way, when the infant horizontally pulls the inlet portion 10 during the process of the mother feeding the infant with the nipple protector, the shoulder portion 20 is easily deformed, so that the orientation and angle of the inlet portion 10 are adjusted. During this process, the infant is insensitive, so as to ensure the comfort of the infant during the feeding process. In other words, after the shoulder portion 20 is deformed due to the infant horizontally pulling the inlet portion 10, the restoring force generated by the shoulder portion 20 is small. In this way, it is not easy for the infant to feel the reverse force provided by the inlet portion 10 to the inner wall of the oral cavity, so that the infant is insensitive, so as to ensure the comfort of the infant during the feeding process.

[0080] In an example of the nipple protector of the present utility model, the nipple protector further includes at least one shoulder reinforcing rib 60, which is integrally formed on the shoulder 20. The shoulder reinforcing rib 60 is used to reinforce the strength of the shoulder 20, so that the shoulder 20 can support the inlet portion 10 on the basis of being easily deformed, and prevent the inlet portion 10 from deforming the shoulder 20 under its own gravity. In other words, by integrally forming the shoulder reinforcing rib 60 on the shoulder 20, the posture of the nipple protector can be kept stable without external force acting on the inlet portion 10.

[0081] In the Figures 1 to 9 specific example of the nipple protector of the present utility model shown in the attached drawings, the shoulder reinforcing rib 60 is formed in a ring shape on the outer side of the shoulder 20, and from a top-down perspective, the shoulder reinforcing rib 60 surrounds the inlet portion 10. In this way, when the mother wears the nipple protector, the shoulder reinforcing rib 60 will not contact the mother's skin, so as to ensure the comfort of the mother when wearing.

[0082] It is worth mentioning that the number of the shoulder reinforcing ribs 60 is not limited in the nipple protector of the present utility model. For example, in the Figures 1 to 9 specific example of the nipple protector of the present utility model shown in the attached drawings, the number of the shoulder reinforcing ribs 60 is two, and the two shoulder reinforcing ribs 60 are arranged concentrically. That is to say, one shoulder reinforcing rib 60 is located inside and one shoulder reinforcing rib 60 is located outside, so that the two shoulder reinforcing ribs 60 are arranged concentrically.

[0083] Optionally, in the Figure 10 deformation example of the nipple protector of the present utility model shown in the attached drawings, the extending direction of the shoulder reinforcing rib 60 is the same as that of the shoulder 20, and the extending direction of the shoulder 20 is perpendicular to the circumferential direction. A group of shoulder reinforcing ribs 60 are arranged in a ring shape on the outer side of the shoulder 20, and from a top-down perspective, a group of shoulder reinforcing ribs 60 surround the inlet portion 10. In this way, the surface of the inner wall of the nipple protector for forming the cavity 40 is smooth. When the mother wears the nipple protector, the shoulder reinforcing rib 60 will not contact the mother's skin, so as to ensure the comfort of the mother when wearing. In the Figure 10 specific example of the nipple protector of the present utility model shown in the attached drawings, the nipple protector includes two groups of shoulder reinforcing ribs 60, one group of shoulder reinforcing ribs 60 is located inside and the other group of shoulder reinforcing ribs 60 is located outside.

[0084] Continue to refer to the attached Figures 1 to 9, the nipple shield further includes a shield 70 which integrally extends outward from a position of the inlet portion 10 adjacent to the shoulder portion 20, and from a top-down perspective, the shield 70 shields at least a part of the shoulder portion 20. In this way, when an infant sucks on the inlet portion 10, the shield 70 can isolate the shoulder portion 20 from the infant's mouth, preventing the shoulder portion 20 from rubbing against the infant's mouth during continuous deformation, thus ensuring the comfort of the infant during sucking.

[0085] Preferably, the shield 70 integrally extends outward and downward from a position of the inlet portion 10 adjacent to the shoulder portion 20, so that the shield 70 shields at least a part of the shoulder portion 20 in an "umbrella" shape. Specifically, the portion of the shoulder portion 20 where the shoulder reinforcing rib 60 is provided is shielded by the shield 70. Thus, on the one hand, the shield 70 makes the shoulder reinforcing rib 60 visually invisible, which is beneficial to improving the aesthetics of the nipple shield. On the other hand, the shield 70 prevents the infant's mouth from contacting the shoulder reinforcing rib 60, improving the comfort of the infant during sucking.

[0086] In a specific example of the nipple shield of the present utility model, an avoidance space 80 and an avoidance opening 90 surrounding the avoidance space 80 are formed between the shield 70 and the shoulder portion 20, that is, the shield 70 and the shoulder portion 20 do not directly contact, avoiding the problem that the shield 70 affects the deformation of the shoulder portion 20. That is to say, the setting of the shield 70 can not only isolate the infant's mouth from the shoulder portion 20, preventing the shoulder portion 20 from rubbing against the infant's mouth during continuous deformation, but also does not affect the deformation of the shoulder portion 20, enabling the orientation and angle of the inlet portion 10 to be flexibly adjusted to adapt to the mother's posture of feeding the infant. In addition, the inlet portion 10, the fitting base portion 30 and the shield 70 form the general appearance of the nipple shield. By setting the shield 70 and shielding the shoulder portion 20 with the shield 70, it is beneficial to improve the aesthetics of the nipple shield.

[0087] Refer to the attached Figure 4 and Figure 7 , in a specific example of the nipple shield of the present utility model, the distance L1 between the outer edge of the shield 70 and the central axis of the nipple shield is less than the distance L2 between the top of the fitting base portion 30 and the central axis. In this way, the shield 70 does not affect the upward turning of the fitting base portion 30, facilitating the mother to wear the nipple shield.

[0088] Refer to the attached Figures 1 to 3 , Figure 5 and Figure 6, the nipple shield further includes at least one soothing portion 100, the soothing portion 100 is disposed on the shield 70, and the soothing portion 100 protrudes toward the inlet portion 10, wherein the soothing portion 100 is used to simulate the Montgomery's tubercles of the mother's areola. When the infant sucks milk through the nipple shield, the soothing portion 100 can stimulate the touch and vision of the infant to help the infant adapt to the nipple shield more quickly. Preferably, the number of the soothing portions 100 of the nipple shield is plural, and these soothing portions 100 are arranged in a ring around the inlet portion 10. More preferably, the soothing portion 100 is formed by a group of bumps.

[0089] Refer to the attached Figure 7 and Figure 8 , before the mother wears the nipple shield, the fitting base 30 can be turned up first, that is, the fitting base 30 is turned toward the direction where the inlet portion 10 is located. Since the thickness dimension of the portion of the fitting base 30 adjacent to the shoulder 20 is greater than the thickness dimension of the shoulder 20, and the distance L1 between the outer edge of the shield 70 and the central axis of the nipple shield is less than the distance L2 between the top of the fitting base 30 and the central axis of the nipple shield, after turning up the fitting base 30, the fitting base 30 and the shield 70 do not contact, avoiding the shield 70 pushing the fitting base 30 outward, so that the fitting base 30 can be kept in the turned-up state. The purpose of turning up the fitting base 30 is to facilitate the alignment of the inlet portion 10 with the nipple. After the mother attaches the nipple shield to the breast in such a way that the inlet portion 10 is aligned with the nipple and areola area and presses against the connection position of the inlet portion 10 and the shoulder 20, turn over the fitting base 30 to form the negative pressure space 1000 between the breast, the fitting base 30 and the shoulder 20. In this way, the mother adsorbs the nipple shield to the breast, so that the mother wears the nipple shield. It can be understood that when the mother wears the nipple shield, the fitting base 30 may not be turned up either.

[0090] Refer to the attached Figure 9, when the infant holds the inlet portion 10 in the mouth and nurses, on the one hand, the milk discharged from the mother's breast reaches the infant's oral cavity through the liquid discharge channel 11 of the inlet portion 10 and is swallowed by the infant. On the other hand, when the mother adjusts the posture of nursing the infant, the infant pulls the inlet portion 10 horizontally, and the inlet portion 10 pulls the shoulder portion 20 to deform the shoulder portion 20, so as to allow the orientation and angle of the inlet portion 10 to be adaptively adjusted to the state of the mother's nursing posture. On the other hand, during the process of the mother nursing the infant, even if the mother adjusts the nursing posture, the orientation and angle of the inlet portion 10 will automatically change with the change of the mother's nursing posture, so that the orientation and angle of the inlet portion 10 are adaptively adjusted to the state of the mother's nursing posture.

[0091] Appendix Figures 11 to 13 shows a deformation example of the nipple shield according to the above preferred embodiment of the present invention. Different from the nipple shield shown in the appendix Figures 1 to 9 shown, in this specific example of the nipple shield shown in the appendix Figures 11 to 13 shown, the nipple shield further includes a one-way valve 110, and the one-way valve 110 is integrally formed on the fitting base 30. After the mother wears the nipple shield and forms the negative pressure space 1000 between the breast, the fitting base 30 and the shoulder portion 20, the one-way valve 110 is arranged to discharge the air in the negative pressure space 1000 or allow the negative pressure space 1000 to intake air.

[0092] Specifically, after the mother wears the nipple shield and forms the negative pressure space 1000 between the breast, the fitting base 30 and the shoulder portion 20, the user can press the fitting base 30 to reduce the volume of the negative pressure space 1000, so as to allow the space in the negative pressure space 1000 to be discharged through the one-way valve 110, thereby reducing the air pressure in the negative pressure space 1000, which enables the nipple shield to be reliably adsorbed on the breast. Before the mother removes the nipple shield from the breast, pinch the one-way valve 110 to deform it to allow the air in the external environment to enter the negative pressure space 1000 through the one-way valve 110. At this time, the negative pressure space 1000 can return to normal pressure, so that the mother can conveniently remove the nipple shield from the breast.

[0093] Further, the fitting base 30 has an exhaust passage 31, the exhaust passage 31 communicates with the cavity 40, and the one-way valve 110 is arranged to be able to open or close the exhaust passage 31 of the fitting base 30. When the one-way valve 110 opens the exhaust passage 31 of the fitting base 30, the air in the negative pressure space 1000 formed between the breast, the fitting base 30 and the shoulder 20 is allowed to be discharged to the external environment through the one-way valve 110 and the exhaust passage 31 of the fitting base 30. Thus, a negative pressure environment is formed in the cavity 40 of the nipple shield, so that the nipple shield can be reliably worn at the breast position.

[0094] In an example of the nipple shield of the utility model, the one-way valve 110 includes a first valve piece 1101 and a second valve piece 1102. The first valve piece 1101 and the second valve piece 1102 respectively extend integrally and obliquely from opposite sides of the exhaust passage 31 of the fitting base 30. And in the natural state, the ends of the first valve piece 1101 and the second valve piece 1102 are in contact with each other to close the exhaust passage 31 of the fitting base 30 by the first valve piece 1101 and the second valve piece 1102. When the mother uses her finger to deform at least one of the first valve piece 1101 and the second valve piece 1102, a gap is generated between the ends of the first valve piece 1101 and the second valve piece 1102, so that the first valve piece 1101 and the second valve piece 1102 open the exhaust passage 31 of the fitting base 30.

[0095] Preferably, the first valve piece 1101 and the second valve piece 1102 are received in the exhaust passage 31 of the fitting base 30, so as to prevent the first valve piece 1101 and the second valve piece 1102 from protruding into the cavity 40 and affecting the comfort of the mother wearing the nipple shield, and to prevent the first valve piece 1101 and the second valve piece 1102 from protruding out of the fitting base 30 and causing the one-way valve 110 to be misoperated. In other words, the one-way valve 110 is received in the exhaust passage 31 of the fitting base 30 to prevent the one-way valve 110 from protruding out of the fitting base 30 and causing the one-way valve 110 to be misoperated.

[0096] Optionally, in other examples of the nipple shield of the present utility model, the one-way valve 110 is installed on the fitting base 30.

[0097] Refer to the attached drawings in the specification of the present utility model Figures 14 to 24, a baby bottle according to another preferred embodiment of the present utility model will be disclosed and described hereinafter, wherein the baby bottle includes a nipple 100A and a bottle body 200A, and the nipple 100A is detachably mounted at the mouth of the bottle body 200A.

[0098] Specifically, the nipple 100A includes a teat portion 10A, a connecting portion 20A, and a mounting portion 30A, and the nipple 100A has a nipple cavity 40A and a liquid outlet 50A communicating with the nipple cavity 40A, wherein the connecting portion 20A extends integrally outward from the bottom of the teat portion 10A, the mounting portion 30A extends integrally downward from the bottom of the connecting portion 20A, the teat portion 10A, the connecting portion 20A, and the mounting portion 30A together form the nipple cavity 40A, and the liquid outlet 50A is formed in the teat portion 10A.

[0099] The hardness of the root of the teat portion 10A is greater than that of the connecting portion 20A, which makes the connecting portion 20A more deformable than the teat portion 10A. In the baby bottle of the present utility model, the root of the teat portion 10A refers to the portion of the teat portion 10A for connecting the connecting portion 20A, that is, the hardness of the portion of the teat portion 10A for connecting the connecting portion 20A is greater than the hardness of the connecting portion 20A. In some embodiments of the baby bottle of the present utility model, in order to make the hardness of the root of the teat portion 10A greater than that of the connecting portion 20A, the thickness dimension of the root of the teat portion 20A is greater than the thickness dimension of the connecting portion 20A.

[0100] That is to say, the teat portion 10A, the connecting portion 20A, and the mounting portion 30A of the nipple 100A are integrally formed. For example, based on an injection molding process, a silicone material can be used to make the integrally formed nipple 100A. And, during the process of integrally molding the teat portion 10A, the connecting portion 20A, and the mounting portion 30A of the nipple 100A, the nipple cavity 40A and the liquid outlet 50A of the nipple 100A are formed synchronously.

[0101] The mounting portion 30A of the nipple 100A is detachably mounted at the mouth of the bottle body 200A. Fluids such as breast milk, prepared milk powder, and water can be contained in the bottle body 200A. When a feeder such as a parent holds the bottle body 200A, an infant is allowed to hold the nipple portion 10A in the mouth to perform a feeding action. When the head of the infant swings relative to the hand of a feeder such as a parent (for example, when the head of the infant shakes), since the infant holds the nipple portion 10A in the mouth, the head of the infant will laterally pull the nipple portion 10A. Because the hardness of the root of the nipple portion 10A is greater than the hardness of the connecting portion 20A, this makes the connecting portion 20A more likely to deform relative to the root of the nipple portion 10A. Thus, the nipple portion 10A further laterally pulls the connecting portion 20A to deform the connecting portion 20A, allowing the orientation and angle of the nipple portion 10A to be adjusted adaptively, reducing or even avoiding the movement of the nipple portion 10A relative to the mouth of the infant. This can not only protect the inner wall of the infant's oral cavity but also avoid the problem of the nipple portion 10A falling out of the infant's oral cavity. It is worth mentioning that "laterally" refers to the direction perpendicular to the extending direction of the nipple portion 10A.

[0102] In the milk bottle of the present utility model, the nipple 100A is a gyrobody. In this way, when a feeder such as a parent feeds an infant through the milk bottle, there is no need to pay attention to the orientation of the nipple portion 10A. When the infant holds the nipple portion 10A in the mouth and laterally pulls the nipple portion 10A, the connecting portion 20A can generate deformation so that the orientation and angle of the nipple portion 10A are adjusted adaptively with the swing of the infant's head.

[0103] Preferably, the connecting portion 20A of the nipple 100A extends obliquely between the bottom of the nipple portion 10A and the top of the mounting portion 30A. That is, the height position of the portion of the connecting portion 20A for connecting the nipple portion 10A is higher than the height position of the portion of the connecting portion 20A for connecting the mounting portion 30A. In this way, the nipple portion 10A is allowed to be slightly away from the hard bottle body 200A, so as to avoid the mouth of the infant hitting the bottle body 200A when the infant uses the milk bottle to feed.

[0104] In an embodiment of the milk bottle of the present utility model, refer to the attached Figures 17 to 20, the nipple 100A further includes at least one annular first reinforcing rib 60A, which is convexly provided on the inner wall of the nipple portion 10A to enhance the structural strength of the nipple portion 10A, so that the nipple portion 10A can maintain the shape of the nipple and is not easily damaged, for the nipple portion 10A to simulate the shape of the nipple and extend the service life of the nipple 100A. And, since the first reinforcing rib 60A protrudes from the inner wall of the nipple portion 10A, the outer wall of the nipple portion 10A can be smooth to avoid the first reinforcing rib 60A affecting the touch feeling when an infant holds the nipple portion 10A in the mouth. Preferably, the first reinforcing rib 60A and the nipple portion 10A are of an integral structure.

[0105] It is worth mentioning that the number of the first reinforcing ribs 60A of the nipple 100A is not limited in the milk bottle of the present invention. For example, in this specific example of the milk bottle shown in the appendix Figures 14 to 24 , the number of the first reinforcing ribs 60A is two, and the two first reinforcing ribs 60A are arranged on the inner wall of the nipple portion 10A at intervals. Optionally, in other examples of the milk bottle of the present invention, the first reinforcing rib 60A extends spirally along the extending direction of the nipple portion 10A. In this way, the first reinforcing rib 60A can prevent the opposite inner side surfaces of the inner wall of the connecting portion 20A from fitting together, thereby preventing the inner wall of the connecting portion 20A from sticking.

[0106] In an embodiment of the milk bottle of the present invention, referring to the appendix Figures 17 to 20 , the nipple 100A further includes at least one annular second reinforcing rib 70A, which is convexly provided on the outer wall of the connecting portion 20A to enhance the structural strength of the connecting portion 20A, so that the connecting portion 20A supports the nipple portion 10A on the basis of being deformable, and prevents the nipple portion 10A from deforming the connecting portion 20A due to its own gravity. That is to say, in the case where the nipple portion 10A does not horizontally pull the connecting portion 20A, the shape of the nipple 100A can be kept stable. Preferably, the second reinforcing rib 70A and the connecting portion 20A are of an integral structure.

[0107] It is worth mentioning that the number of the second reinforcing ribs 70A of the nipple 100A is not limited in the milk bottle of the present invention. For example, in this specific example of the milk bottle shown in the appendix Figures 14 to 24 , the number of the second reinforcing ribs 70A is two, and the two second reinforcing ribs 70A are arranged on the outer wall of the connecting portion 20A at intervals.

[0108] In an embodiment of the milk bottle of the present utility model, referring to the appendix Figures 17 to 20 , the thickness dimension of the connecting portion 20A of the nipple 100A is smaller than the thickness dimension of the nipple portion 10A adjacent to the connecting portion 20A, and the thickness dimension of the connecting portion 20A is smaller than the thickness dimension of the mounting portion 30A adjacent to the connecting portion 20A. That is, with respect to the thickness of the nipple portion 10A adjacent to the connecting portion 20A and the thickness of the mounting portion 30A adjacent to the connecting portion 20A, the connecting portion 20A has a thinner thickness dimension. In this way, the connecting portion 20A is easily deformed to enable flexible adjustment of the orientation and angle of the nipple portion 10A. At the same time, the connecting portion 20A can have a smaller restoring force, so that it is not easy for infants to feel the reaction force provided by the nipple portion 10A to the inner wall of the oral cavity. Thus, after the orientation and angle of the nipple portion 10A are adaptively adjusted, infants are insensitive, so as to improve the comfort of infants when using the milk bottle for feeding.

[0109] In an embodiment of the milk bottle of the present utility model, continuing to refer to the appendix Figures 14 to 24 , the nipple 100A further includes a protective umbrella 80A, and the protective umbrella 80A extends integrally outward from the middle of the nipple portion 10A to above the connecting portion 20A. In this way, when an infant holds the nipple portion 10A in the mouth for feeding, the protective umbrella 80A can isolate the connecting portion 20A from the infant's mouth, avoiding the connecting portion 20A from rubbing the infant's mouth during continuous deformation, so as to ensure the comfort of the infant when using the milk bottle for feeding. And there is a gap between the protective umbrella 80A and the connecting portion 20A of the nipple 100A to prevent the protective umbrella 80A from affecting the deformation of the connecting portion 20A.

[0110] In other words, in an embodiment of the milk bottle of the present utility model, the nipple 100A not only can isolate the connecting portion 20A from the infant's mouth by extending the protective umbrella 80A from the middle of the nipple portion 10A to above the connecting portion 20A and having a gap between the protective umbrella 80A and the connecting portion 20A, so as to protect the infant's mouth when the infant uses the milk bottle for feeding, but also avoids the protective umbrella 80A from affecting the deformation of the connecting portion 20A, enabling flexible adaptive adjustment of the orientation of the nipple portion 10A.

[0111] Preferably, in a specific example of the milk bottle of the present invention, the protective umbrella 80A extends to a position where the second reinforcing rib 70A is blocked. In this way, the second reinforcing rib 70A is not visually visible, so as to improve the aesthetics of the nipple 100A and prevent the second reinforcing rib 70A from contacting the mouth of the infant.

[0112] In an embodiment of the milk bottle of the present invention, referring to the attached Figure 8 , the nipple 100A further includes at least one air inlet valve 90A, and the air inlet valve 90A is arranged to integrally extend downward from the connecting portion 20A. After the nipple 100A is installed at the bottle mouth of the bottle body 200A, the air inlet valve 90A can communicate the internal space of the bottle body 200A and the external environment. When the infant uses the milk bottle to eat, the air in the external environment can enter the internal environment of the bottle body 200A through the air inlet valve 90A to help the infant eat smoothly.

[0113] It is worth mentioning that the number of the air inlet valves 90A of the nipple 100A is not limited in the milk bottle of the present invention and is set according to needs. For example, in this specific example of the milk bottle of the present invention shown in the attached Figures 14 to 24 , the number of the air inlet valves 90A of the nipple 100A is two.

[0114] Furthermore, continuing to refer to the attached Figure 21 , from the side view perspective, the end of the air inlet valve 90A is lower than the bottom of the mounting portion 30A. Thus, when the infant uses the milk bottle to eat, the end of the air inlet valve 90A can be exposed above the liquid level to avoid the air entering the internal environment of the bottle body 200A through the air inlet valve 90A from forming bubbles in the food inside the bottle body 200A, which is crucial for preventing the infant from hiccupping.

[0115] In an embodiment of the milk bottle of the present invention, continuing to refer to the attached Figures 14 to 20, the feeding bottle further includes a pressing cap 300A which has a pressing cap passage 301A. The mounting portion 30A of the nipple 100A extends from above the pressing cap 300A to below through the pressing cap passage 301A of the pressing cap 300A, so that the pressing cap 300A is sleeved on the mounting portion 30A of the nipple 100A. The pressing cap 300A is detachably mounted at the bottle mouth of the bottle body 200A. For example, the pressing cap 300A can be screwed onto the bottle mouth of the bottle body 200A. Specifically, the inner wall of the pressing cap 300A has an internal thread structure, and the bottle mouth of the bottle body 200A has an external thread structure. The internal thread structure of the pressing cap 300A and the external thread structure at the bottle mouth of the bottle body 200A cooperate with each other to enable the pressing cap 300A to be screwed onto the bottle mouth of the bottle body 200A. After the pressing cap 300A is mounted at the bottle mouth of the bottle body 200A, the pressing cap 300A presses a part of the mounting portion 30A of the nipple 100A towards the end face at the bottle mouth of the bottle body 200A to mount the mounting portion 30A at the bottle mouth of the bottle body 200A. Preferably, after the pressing cap 300A is mounted at the opening of the bottle body 200A, the pressing cap 300A and the bottle body 200A can cooperate with each other to press the mounting portion 30A of the nipple 100A into a slightly deformed state to prevent a gap from being generated between the mounting portion 30A and the end face at the bottle mouth of the bottle body 200A, thereby avoiding liquid leakage at the mounting position of the mounting portion 30A and the bottle body 200A.

[0116] Further, the mounting portion 30A of the nipple 100A has an annular groove 31A, and the edge position 302A of the pressing cap 300A for forming the pressing cap passage 301A extends into the groove 31A of the mounting portion 30A, so that a part of the mounting portion 30A is pressed towards the end face at the bottle mouth of the bottle body 200A by the edge position 302A of the pressing cap 300A, thereby enabling the nipple 100A to be reliably mounted at the bottle mouth of the bottle body 200A.

[0117] Specifically, the mounting portion 30A includes a transition portion 32A, a longitudinally extending arm 33A, and a laterally extending arm 34A. The transition portion 32A is connected to the bottom of the connecting portion 20A. The longitudinally extending arm 33A integrally extends downward from the inner side of the transition portion 32A. The laterally extending arm 34A integrally extends outward from the bottom of the longitudinally extending arm 33A, so as to form the groove 31A between the transition portion 32A, the longitudinally extending arm 33A, and the laterally extending arm 34A. In other words, the longitudinally extending arm 33A is the retracted position of the mounting portion 30A. The edge position 302A of the gland 300A extends to the groove 31A of the mounting portion 30A. After the gland 300A is mounted on the mouth of the bottle body 200A, the edge position 302A of the gland 300A tightly presses the laterally extending arm 34A of the mounting portion 30A against the end face at the mouth of the bottle body 200A, so that the nipple 100A is hermetically mounted at the mouth of the bottle body 200A.

[0118] Preferably, in a specific example of the milk bottle of the present utility model, the size of the end position 341A of the laterally extending arm 34A of the mounting portion 30A of the nipple 100A is larger than the size of the main body position 342A. At least one of the gland 300A and the mouth of the bottle body 200A is provided with a fitting groove 400A. The main body position 342A of the laterally extending arm 34A is clamped between the laterally extending arm 34A of the gland 300A and the end face at the mouth of the bottle body 200A. The end position 341A of the laterally extending arm 34A is held in the fitting groove 400A. In this way, the gland 300A and the bottle body 200A cooperate with each other to prevent the mounting portion 30A of the nipple 100A from displacing relative to the bottle body 200A, ensuring that the nipple 100A is reliably mounted at the opening of the bottle body 200A.

[0119] Attached Figures 25 to 28 shows a variant example of the milk bottle. Different from the milk bottle shown in Attached Figures 14 to 24 shown, in this specific example of the milk bottle shown in Attached Figures 25 to 28 shown, the nipple 100A is not provided with the air inlet valve 90A. When an infant uses the milk bottle to eat, in order to allow the air in the external environment to enter the internal space of the bottle body 200A, the milk bottle further includes a flow control unit 500A, wherein the flow control unit 500A is arranged on the bottle body 200A, and the flow control unit 500A is arranged to allow the air in the external environment to enter the internal space of the bottle body 200A to help the infant eat smoothly.

[0120] Specifically, the bottom of the bottle body 200A has a bottle body perforation 201A. The flow control unit 500A includes a valve body part 501A, a resting part 502A, and a skeleton part 503A. The resting part 502A extends integrally around from the bottom end of the valve body part 501A. The skeleton part 503A is disposed on the resting part 502A. For example, based on the insert molding process, the skeleton part 503A can be disposed on the resting part 502A, and the skeleton part 503A surrounds the bottom end of the valve body part 501A to maintain the shape of the valve body part 501A. The shape of the valve body part 501A matches the shape of the bottle body perforation 201A of the bottle body 200A, and the size of the valve body part 501A is slightly larger than the size of the bottle body perforation 201A of the bottle body 200A. When the top end of the valve body part 501A is inserted into the bottle body perforation 201A of the bottle body 200A, the edge of the bottle body perforation 201A of the bottle body 200A squeezes the valve body part 501A, causing the valve body part 501A to deform slightly. After the top end of the valve body part 501A is inserted into the bottle body perforation 201A of the bottle body 200A and the resting part 502A rests on the bottom of the bottle body 200A, the edge of the bottle body perforation 201A of the bottle body 200A and the outer wall of the valve body part 501A are in close contact to prevent water leakage.

[0121] The skeleton part 503A is used to maintain the shape of the valve body part 501A, preventing a gap from being generated between the edge of the bottle body perforation 201A of the bottle body 200A and the outer wall of the valve body part 501A due to the deformation of the peripheral wall of the valve body part 501A, thereby preventing water leakage.

[0122] Preferably, the lateral dimension of the top of the valve body part 501A is larger than the lateral dimension of the middle of the valve body part 501A, that is, the top of the valve body part 501A expands in the circumferential direction to prevent the flow control unit 500A from falling off the bottle body 200A.

[0123] Further, the feeding bottle includes a bottom cover 600A, which is detachably mounted on the flow control unit 500A. When the bottom cover 600A is mounted on the flow control unit 500A, the bottom cover 600A closes the valve body portion 501A of the flow control unit 500A to prevent fluid (such as air, water, etc.) in the external environment from entering the internal space of the bottle body 200A through the valve body portion 501A. When the bottom cover 600A is detached from the flow control unit 500A, the bottom cover 600A opens the valve body portion 501A of the flow control unit 500A to allow air in the external environment to enter the internal space of the bottle body 200A through the valve body portion 501A.

[0124] Specifically, when using a milk warmer to warm the milk contained in the feeding bottle in a water-containing manner, since the bottom cover 600A is mounted on the flow control unit 500A, the bottom cover 600A closes the valve body portion 501A of the flow control unit 500A, so the water in the milk warmer is prevented from entering the internal space of the bottle body 200A through the valve body portion 501A. After the milk warming is completed and when the infant uses the feeding bottle to eat, the bottom cover 600A is detached from the flow control unit 500A. At this time, the valve body portion 501A allows air in the external environment to enter the internal space of the bottle body 200A through the valve body portion 501A to help the infant eat smoothly.

[0125] Attached Figure 29 shows a modified example of the feeding bottle. Different from the feeding bottle shown in Attached Figures 25 to 28 In this specific example of the feeding bottle shown in Attached Figure 29 at the root of the nipple portion 10A of the nipple 100A, there is a ring of reinforcing bosses 111. These reinforcing bosses 111 protrude towards the nipple cavity 40A of the nipple 100A to further strengthen the strength of the root of the nipple portion 10A, so that the root of the nipple portion 10A is not easily deformed.

[0126] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the principle, the embodiments of the present invention can have any deformation or modification.
