[0048] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0049] In the prior art, a nipple shield typically includes a nipple and a shield connected to the nipple. The shield can be placed over the mother's breast, allowing the child to drink milk by sucking on the nipple. However, the space between the shield and the nipple in the prior art is relatively large. During use, the mother's nipple may become stuck between the nipple and the shield, or slip into the internal space of the nipple due to the child's sucking, causing discomfort to the mother's nipple. Furthermore, the shield can easily block the nipple's milk outlet, making it difficult for the child to drink milk.

[0050] In order to solve at least one of the above-mentioned technical problems, an embodiment of the present disclosure provides a nipple shield, comprising a suction nozzle portion, a first cover portion, and a first abutment portion. The suction nozzle portion has a first cavity inside, and the suction nozzle portion is used for sucking. The first cover portion is connected to one end of the suction nozzle portion. The first end of the first cover portion facing away from the suction nozzle portion is used to abut against the breast so that the nipple can be accommodated in the second cavity inside the first cover portion, and the second cavity is connected to the first cavity. The first abutment portion is provided at the connection between the first cavity and the second cavity. The first abutment portion is used to abut against the end of the nipple to prevent the nipple from entering the first cavity from the second cavity. Any embodiment of the present disclosure can prevent the mother's nipple from getting stuck in the connection between the suction nozzle portion and the first cover portion or sliding into the internal space of the suction nozzle portion, thereby avoiding blocking the milk outlet of the nipple, thereby effectively solving the above-mentioned technical problems.

[0051] An embodiment of the present disclosure provides a breast shield, as shown in FIG1 and FIG2 , comprising a nozzle portion 1 , a first covering portion 2 and a first abutting portion 3 .

[0052] The mouthpiece 1 has a first cavity 11 therein, and is used for sucking.

[0053] The first covering portion 2 is connected to one end of the suction nozzle portion 1, and the first end of the first covering portion 2 facing away from the suction nozzle portion 1 is used to abut against the breast so that the nipple can be accommodated in the second cavity 21 inside the first covering portion 2, and the second cavity 21 is connected to the first cavity 11.

[0054] The first abutting portion 3 is provided at the connection between the first cavity 11 and the second cavity 21 . The first abutting portion 3 is used to abut against the end of the nipple to prevent the nipple from entering the first cavity 11 from the second cavity 21 .

[0055] According to an embodiment of the present disclosure, the mouthpiece 1 may be the portion of the shield where the child can suck, and may be provided with a milk outlet. The shape and size of the mouthpiece 1 may be various, for example, the shape of the mouthpiece 1 may be similar to the shape of a nipple, or may be circular.

[0056] The shape of the milk outlet hole of the mouthpiece 1 can be selected and adjusted according to the age of the child. For example, a closable and openable milk outlet hole can be selected for a young child, and a non-closable milk outlet hole can be selected for an older child.

[0057] The mouthpiece 1 may have a first cavity 11 therein. For example, the mouthpiece 1 may have a thin-walled structure, and its internal space may constitute the first cavity 11. The shape and size of the first cavity 11 may be selected and adjusted according to the shape and size of the nipple. For example, first cavities 11 of different sizes, large, medium, and small, may be provided to accommodate children of different ages.

[0058] The first cover portion 2 can be connected to one end of the mouthpiece 1, for example, the end of the mouthpiece 1 facing away from the milk outlet. The connection between the two can be various. For example, the two can be separate structures that are connected into a single structure using a common connection process. Alternatively, the first cover portion 2 can be integrally formed with the mouthpiece 1 to hold the breast. In some embodiments, the mouthpiece 1 and the first cover portion 2 can be integrally formed from silicone.

[0059] The shape and size of the first covering portion 2 can be selected and adjusted according to the shape and size of the breast. For example, first covering portions 2 of different sizes, such as large, medium, and small, can be provided to adapt to the shapes and sizes of breasts of different people.

[0060] The first covering portion 2 can also be a thin-walled structure, and can have a second cavity 21 inside it. The second cavity 21 can communicate with the first cavity 11. Alternatively, the second cavity 21 can be used to accommodate the breast. It is understood that the first covering portion 2 can be positioned outside the breast, so that the nipple and at least part of the breast can be located within the second cavity 21. The shape and size of the second cavity 21 can be selected and adjusted based on the shape and size of the breast. For example, large, medium, and small first cavities 11 can be provided to accommodate the shapes and sizes of breasts of different people.

[0061] As shown in Figure 1, the upper end of the first shield portion 2 corresponds to the second end of the first shield portion 2, which can be connected to the suction nozzle 1. The lower end of the first shield portion 2 is the first end of the first shield portion 2 facing away from the suction nozzle 1, i.e., the first end of the first shield portion 2. The first end of the first shield portion 2 can be used to abut against the breast. It is understood that the first end of the first shield portion 2 can be tightly attached to the breast, so that there is no gap between the first shield portion 2 and the breast.

[0062] The first abutment portion 3 can be a structure extending toward the center of the connection between the suction nozzle portion 1 and the first cover portion 2, thereby reducing the diameter of the connection between the suction nozzle portion 1 and the first cover portion 2 to block the nipple from entering the first cavity 11, or it can be a structure extending obliquely toward the second cavity 21 at the connection between the suction nozzle portion 1 and the first cover portion 2, which can abut against the nipple when the nipple moves toward the first cavity 11 to block the nipple from entering the first cavity 11.

[0063] When the breast shield is in use, the first end of the first covering portion 2 can rest against the breast, achieving close contact between the two. The nipple is located in the second cavity 21, and the child can suck through the suction nozzle portion 1, thereby forming a negative pressure between the entire breast shield and the breast, thereby allowing the milk to be sucked out by the child through the milk outlet hole.

[0064] It can be understood that since negative pressure is formed between the breast shield and the breast during use, the nipple is likely to move toward the suction mouth portion 1 under the action of the negative pressure. The first abutting portion 3 can block the nipple to prevent it from entering the suction mouth portion 1 or getting stuck between the suction mouth portion 1 and the first covering portion 2, thereby reducing the discomfort caused by the nipple entering the suction mouth portion 1 or getting stuck between the suction mouth portion 1 and the first covering portion 2.

[0065] According to the embodiment of the present disclosure, by providing the first covering portion 2, the breast shield can fit the mother's breast when the mother is breastfeeding, preventing the nipple shield from falling off the mother's breast during the child's sucking. A first abutting portion 3 is provided between the first covering portion 2 and the suction nozzle portion 1, which reduces the diameter of the second cavity 21 entering the first cavity 11, allowing the nipple to abut against the first abutting portion 3, preventing the nipple from entering the first cavity 11 from the second cavity 21 or getting stuck in the connection space between the first covering portion 2 and the suction nozzle portion 1, thereby improving the comfort of breastfeeding for the mother.

[0066] In one embodiment, as shown in FIG. 3 , the first abutting portion 3 includes a barrier wall 31 for separating the first cavity 11 from the second cavity 21 , and the barrier wall 31 is provided with a plurality of communicating holes 311 for communicating the first cavity 11 with the second cavity 21 .

[0067] According to an embodiment of the present disclosure, the first abutting portion 3 may include a barrier wall 31. The barrier wall 31 may be a plate-shaped or sheet-shaped structure, and the barrier wall 31 may be a structure provided at the connection between the first cover portion 2 and the nozzle portion 1 to separate the first cavity 11 from the second cavity 21.

[0068] The barrier wall 31 may be provided with a plurality of communication holes 311 , and the communication holes 311 may enable communication between the first cavity 11 and the second cavity 21 .

[0069] The number and size of the communication holes 311 can be selected and adjusted as needed. For example, when breastfeeding a young child, a barrier wall 31 with smaller and fewer communication holes 311 can be used, while when breastfeeding an older child, a barrier wall 31 with larger and more communication holes 311 can be used. The communication holes 311 can also be arranged in an array or radially on the barrier wall 31.

[0070] The barrier wall 31 can be integrally formed with the first shield portion 2 and the mouthpiece portion 1, or it can be removably attached to the breast shield. For example, the first shield portion 2 can be provided with a double-layered annular protrusion, and the barrier wall 31 can be removably installed in the groove between the double-layered annular protrusion to facilitate cleaning. Furthermore, the barrier wall 31 can be a soft, thin sheet, which can enhance the comfort of the mother and child when using the breast shield.

[0071] According to an embodiment of the present disclosure, by providing a barrier wall 31 that divides the first cavity 11 and the second cavity 21, the nipple can be effectively prevented from moving toward the first cavity 11. By providing a plurality of connecting holes 311 on the barrier wall 31, the milk can flow into the first cavity 11 through the plurality of connecting holes 311 for the child to suck, while avoiding blocking the milk outlet hole of the nipple, so that the child can drink the milk.

[0072] In one embodiment, the first abutment portion 3 includes a plurality of first protrusions, which are arranged on the inner wall of the connection between the first cover portion 2 and the suction nozzle portion 1, and the plurality of first protrusions are arranged at circumferential intervals along the connection between the first cover portion 2 and the suction nozzle portion 1, wherein a first gap is provided between each two adjacent first protrusions for connecting the first cavity 11 and the second cavity 21.

[0073] According to an embodiment of the present disclosure, the first protrusion may be a structure provided on the inner wall at the connection between the first cover portion 2 and the nozzle portion 1 , that is, may be a structure provided at the connection between the first cavity 11 and the second cavity 21 .

[0074] The extension direction of the first protrusion can be selected and adjusted as needed, for example, extending toward the central axis of the breast shield, or extending along the central axis of the breast shield and obliquely toward the second cavity 21 .

[0075] The extension length of the first protrusion can be selected and adjusted as needed. For example, there is a certain gap between the ends of multiple first protrusions, and there is also a certain gap (i.e., a first gap) between adjacent protrusions. The first cavity 11 and the second cavity 21 are connected through the gap between the ends and the gap between adjacent first protrusions, or the ends of multiple first protrusions are completely abutted, and the first cavity 11 and the second cavity 21 are connected through the gap between adjacent first protrusions.

[0076] According to the embodiment of the present disclosure, by providing multiple first protrusions, the first cavity 11 and the second cavity 21 can be divided to prevent the nipple from moving toward the first cavity 11. By providing a first gap between two adjacent first protrusions, the milk can flow from the multiple first gaps into the first cavity 11 for the child to suck, while avoiding clogging the milk outlet hole of the nipple.

[0077] In one embodiment, as shown in Figure 4, the first abutment portion 3 is protruded from the inner wall of the connection between the first cover portion 2 and the suction nozzle portion 1, and the first abutment portion 3 extends along the circumference of the connection between the first cover portion 2 and the suction nozzle portion 1 to form an annular first abutment portion 32, and the first central through hole 321 of the annular first abutment portion 32 is used to connect the first cavity 11 and the second cavity 21.

[0078] According to an embodiment of the present disclosure, the first abutting portion 3 may be an annular structure, and may have a first central through hole 321 therein. As shown in FIG4 , the width between the inner and outer walls of the annular first abutting portion 32 may be selected and adjusted as needed. In other words, the contact surface between the annular first abutting portion 32 and the nipple may be selected and adjusted as needed. For example, a wider annular first abutting portion 32 may be provided to contact the nipple over a larger area.

[0079] The first central through hole 321 is equivalent to the region where the inner diameter of the annular first abutting portion 32 is located, that is, the hole wall of the first central through hole 321 is equivalent to the inner wall of the annular first abutting portion 32 .

[0080] The size of the first central through hole 321 can be selected and adjusted as needed. For example, a smaller first central through hole 321 can be set to prevent the nipple from moving toward the first cavity 11 .

[0081] According to an embodiment of the present disclosure, an annular first abutting portion 32 is provided to abut the nipple to prevent the nipple from moving toward the first cavity 11. By providing a first central through hole 321, lotion can flow from the first central through hole 321 into the first cavity 11 for the child to suck, while avoiding clogging the milk outlet hole of the nipple.

[0082] In one embodiment, as shown in FIG. 4 , a surface of the annular first abutting portion 32 facing the second cavity 21 is provided with a plurality of first grooves 322 , and the plurality of first grooves 322 all extend along the radial direction of the annular first abutting portion 32 .

[0083] According to the embodiment of the present disclosure, the recessed direction of the first groove 322 is the depth direction, and the distance between the two side walls of the first groove 322 on the surface of the first abutting portion 3 is the width of the first groove 322. The width of the first groove 322 can be selected and adjusted as needed. For example, when used for young children, a first groove 322 with a smaller width is selected to reduce the flow of lotion to the first cavity 11. When used for older children, a first groove 322 with a larger width is selected to increase the flow of lotion to the first cavity 11.

[0084] In the extension direction of the first groove 322, the depth of the first groove 322 can remain fixed, or can also change. For example, the bottom of the first groove 322 is shallower at one end close to the first cover portion 2, and the bottom of the first groove 322 is deeper at one end close to the first central through hole 321, so that the emulsion can flow smoothly from the first groove 322 into the first cavity 11.

[0085] The number of the first grooves 322 can be selected and adjusted as needed. For example, a larger number of first grooves 322 can be selected to reduce the distance between two adjacent first grooves 322 to prevent the groove wall between two adjacent first grooves 322 from blocking the milk outlet of the nipple.

[0086] The extending direction of the first groove 322 may be a direction in which the first groove 322 extends outward from the center of the ring shape.

[0087] According to an embodiment of the present disclosure, by providing a plurality of radially extending first grooves 322 on the first abutting portion 3, when the first abutting portion 3 abuts against the end of the nipple, milk can flow into the first cavity 11 through the plurality of first grooves 322, thereby preventing the first abutting portion 3 from blocking the milk outlet hole.

[0088] In one embodiment, a surface of the annular first abutting portion 32 facing the second cavity 21 is provided with a plurality of first grooves 322 , and the plurality of first grooves 322 all extend along the circumference of the annular first abutting portion 32 .

[0089] According to the embodiment of the present disclosure, the number of first grooves 322 can be selected and adjusted as needed. For example, a larger number of first grooves 322 can be selected to reduce the distance between two adjacent first grooves 322 to avoid the groove wall between two adjacent first grooves 322 blocking the milk outlet of the nipple.

[0090] The length of the first groove 322 extending along the circumferential direction of the annular first abutting portion 32 can be selected and adjusted as needed, for example, it can be extended into an annular first groove or an arc-shaped first groove.

[0091] According to an embodiment of the present disclosure, by providing a plurality of circumferentially extending first grooves 322 on the annular first abutting portion 32 , when the annular first abutting portion 32 abuts against the end of the nipple, the first abutting portion 3 is prevented from blocking the milk outlet hole.

[0092] In one embodiment, as shown in Figures 1 and 2, the breast shield further includes a second abutment portion 4. The second abutment portion 4 is provided on the inner wall of the first shield portion 2, and the second abutment portion 4 is provided adjacent to the first abutment portion 3, and the second abutment portion 4 is a non-planar structure.

[0093] According to an embodiment of the present disclosure, the second abutting portion 4 may be a non-planar structure adjacent to the first abutting portion 3 and protruding or recessed on the inner wall of the first covering portion 2. When the nipple moves toward the first cavity 11, it first abuts the second abutting portion 4. When the nipple is subjected to a strong suction force, the nipple continues to move toward the first cavity 11 until it abuts against both the second abutting portion 4 and the first abutting portion 3. The non-planar structure herein may be a structure in which the surface of the second abutting portion 4 is non-smooth, for example, the surface of the second abutting portion 4 is provided with a plurality of protrusions, recesses, or ripples.

[0094] According to the embodiment of the present disclosure, by providing the second abutting portion 4, when the nipple moves toward the first cavity 11, it is used to abut against part of the nipple area to avoid the nipple being fully subjected to the force of the first abutting portion 3, causing discomfort to the mother. At the same time, by arranging the second abutting portion 4 adjacent to the first abutting portion 3, it is possible to avoid part of the milk outlet hole contacting the inner wall of the first cover portion 2 and causing blockage.

[0095] In one embodiment, the second abutment portion 4 includes a plurality of second protrusions protruding from the inner wall of the first cover portion 2, and the plurality of second protrusions are arranged at intervals along the circumference of the first cover portion 2, wherein a second gap is provided between each two adjacent second protrusions for the emulsion to flow into the first cavity 11.

[0096] According to the embodiment of the present disclosure, the extension direction of the second protrusion can be selected and adjusted as needed, for example, extending toward the central axis of the nipple shield, or extending obliquely toward the second cavity 21.

[0097] The extension length of the second protrusion can be selected and adjusted as needed. For example, there is a certain gap between the ends of multiple second protrusions, and there is also a certain gap (i.e., the second gap) between adjacent second protrusions. The emulsion produced by the nipple can flow into the first cavity 11 through the gap between the ends and the gap between adjacent second protrusions at the same time.

[0098] According to an embodiment of the present disclosure, by providing a plurality of second protrusions, the movement of the nipple toward the first cavity 11 can be restricted, and by providing a second gap between two adjacent second protrusions, the milk can flow from the plurality of second gaps toward the first cavity 11 for the child to suck, while avoiding clogging the milk outlet of the nipple.

[0099] In one embodiment, as shown in Figure 5, the second abutment portion 4 protrudes from the inner wall of the first cover portion 2 and extends along the circumference of the first cover portion 2 to form an annular second abutment portion 41. The second central through hole 411 of the annular second abutment portion 41 is connected to the first cavity 11, and a plurality of second grooves 412 are provided on the surface of the annular second abutment portion 41 facing the first end of the first cover portion 2. The plurality of second grooves 412 all extend radially along the annular second abutment portion 41.

[0100] According to an embodiment of the present disclosure, the second abutting portion 4 can be an annular structure, which can have a second central through hole 411 inside. As shown in Figure 5, the width between the inner wall and the outer wall of the annular second abutting portion 41 can be selected and adjusted as needed. That is to say, the contact surface between the annular second abutting portion 41 and the nipple can be selected and adjusted as needed. For example, a wider annular second abutting portion 41 is provided to contact the nipple over a larger area.

[0101] The second central through hole 411 is equivalent to the region where the inner diameter of the annular second abutting portion 41 is located, that is, the hole wall of the second central through hole 411 is equivalent to the inner wall of the second abutting portion 4 .

[0102] The size of the second central through hole 411 can be selected and adjusted as needed. For example, the size of the second central through hole 411 is set to be slightly larger than the size of the first central through hole 321 of the first abutting portion 3, so that part of the nipple can abut against the second abutting portion 4, and the end part of the nipple can abut against the first abutting portion 3.

[0103] Taking the concave direction of the second groove 412 as the depth direction, the distance between the two side walls of the second groove 412 on the surface of the annular second abutment portion 41 is the width of the second groove 412. The width of the second groove 412 can be selected and adjusted as needed. For example, when used for young children, a second groove 412 with a smaller width is selected to reduce the flow of lotion to the first cavity 11. When used for older children, a second groove 412 with a larger width is selected to increase the flow of lotion to the first cavity 11.

[0104] In the extension direction of the second groove 412, the depth of the second groove 412 can remain fixed, or can also change. For example, the bottom of the second groove 412 is shallower at one end close to the first cover portion 2, and the bottom of the second groove 412 is deeper at one end away from the first cover portion 2, so that the emulsion can flow smoothly from the second groove 412 to the first cavity 11.

[0105] The number of the second grooves 412 can be selected and adjusted as needed. For example, a larger number of second grooves 412 can be selected to reduce the distance between two adjacent second grooves 412 to prevent the groove wall between two adjacent second grooves 412 from blocking the milk outlet of the nipple.

[0106] The extending direction of the second groove 412 may be a direction in which the second groove 412 extends outward from the center of the ring shape.

[0107] According to an embodiment of the present disclosure, an annular second abutting portion 41 is provided to abut a partial area of ​​the nipple to limit the movement of the nipple toward the first cavity 11. A second central through hole 411 is provided and a plurality of radially extending second grooves 412 are provided on the annular second abutting portion 41, so that part of the emulsion can flow from the second grooves 412 through the second central through hole 411 into the first cavity 11 for the child to suck, while avoiding clogging the milk outlet of the nipple.

[0108] In one embodiment, the second abutment portion 4 protrudes from the inner wall of the first cover portion 2 and extends along the circumference of the first cover portion 2 to form an annular second abutment portion 41. The second central through hole 411 of the annular second abutment portion 41 is connected to the first cavity 11. The surface of the annular second abutment portion 41 facing the first end of the first cover portion 2 is provided with a plurality of second grooves 412, and the plurality of second grooves 412 all extend along the circumference of the annular second abutment portion 41.

[0109] According to the embodiment of the present disclosure, the number of second grooves 412 can be selected and adjusted as needed. For example, a larger number of second grooves 412 can be selected to reduce the distance between two adjacent second grooves 412 to avoid the groove wall between two adjacent second grooves 412 blocking the milk outlet of the nipple.

[0110] The length of the second groove 412 extending along the circumferential direction of the second abutting portion 4 can be selected and adjusted as needed, for example, it can be extended into an annular second groove or an arc-shaped second groove.

[0111] According to an embodiment of the present disclosure, by providing a plurality of circumferentially extending second grooves 412 on the annular second abutting portion 41 , the annular second abutting portion 41 can be prevented from blocking the milk outlet hole of the nipple when the annular second abutting portion 41 abuts against the nipple.

[0112] In one embodiment, the second abutting portion 4 includes a plurality of third grooves, each of which is arranged at intervals on the inner wall of the first covering portion 2 , and each of the third grooves extends along the circumference of the first covering portion 2 .

[0113] According to the embodiment of the present disclosure, the number of third grooves can be selected and adjusted as needed. For example, a larger number of third grooves can be selected to reduce the distance between two adjacent third grooves to avoid the inner wall of the first covering portion 2 between two adjacent third grooves blocking the milk outlet of the nipple.

[0114] The length of the third groove extending along the circumferential direction of the first covering portion 2 can be selected and adjusted as needed. For example, the third groove can be extended into an annular third groove or an arc-shaped third groove.

[0115] According to an embodiment of the present disclosure, by providing a plurality of circumferentially extending third grooves on the first covering portion 2, when the inner wall of the first covering portion 2 abuts against the nipple, the inner wall of the first covering portion 2 can be prevented from blocking the milk outlet of the nipple.

[0116] In one embodiment, as shown in FIG2 , the breast shield further includes a first raised portion 5 and a second shield portion 6 for contacting the breast. The first raised portion 5 protrudes from the inner wall of the first shield portion 2. The first end of the second shield portion 6 is disposed on the inner wall of the first shield portion 2, and the second end of the second shield portion 6 extends toward the first end of the first shield portion 2. Furthermore, the second end of the second shield portion 6 is spaced apart from the first shield portion 2. The first raised portion 5 is located between the first end of the second shield portion 6 and the first end of the first shield portion 2, and a receiving space 7 is defined between the first raised portion 5 and the first end of the second shield portion 6. The receiving space 7 is configured to provide deformation space for the second shield portion 6 when the second shield portion 6 contacts the breast.

[0117] According to an embodiment of the present disclosure, the first protrusion 5 can be a structure protruding from the inner wall of the first covering portion 2 and located near the first end of the first covering portion 2. When the second cavity 21 accommodates the breast, the first protrusion 5 abuts against the breast to close the gap between the first end of the first covering portion 2 and the breast, thereby preventing some of the emulsion in the second cavity 21 from flowing out of the first end of the first covering portion 2.

[0118] As shown in Figure 2, the first end of the second covering portion 6 can be set on the inner wall of the first covering portion 2, and the second end of the second covering portion 6 can extend obliquely so that the end can extend in a direction close to the first end of the first covering portion 2.

[0119] The second shield portion 6 can be a structure that protrudes from the inner wall of the first shield portion 2 and is located near one end of the suction nozzle portion 1. When the second cavity 21 accommodates the breast, the second shield portion 6 abuts against the breast. Since the first protrusion 5 and the second shield portion 6 are both protruding structures, an accommodating space 7 is formed between the inner wall of the partial area of ​​the first shield portion 2 located between the first protrusion 5 and the second shield portion 6 and the breast. When the breast shield shakes, the accommodating space 7 can provide an area for the second abutting portion 4 to move, so that the second abutting portion 4 can firmly abut against the breast. At the same time, it can prevent some of the lotion in the second cavity 21 from flowing out of the first end of the first shield portion 2.

[0120] The second end of the second covering portion 6 is spaced apart from the first covering portion 2. This means that no matter where the first end of the second covering portion 6 is located on the first covering portion 2, the second end of the second covering portion 6 is away from the inner wall of the first covering portion 2, so that the second covering portion 6 is formed as a smaller covering body inside the first covering portion 2 for covering the nipple.

[0121] In some embodiments, the first protrusion 5 and the second covering portion 6 may be annular structures extending along the circumference of the first covering portion 2 , thereby improving sealing performance.

[0122] According to the embodiment of the present disclosure, by providing the first protrusion 5 and the second cover portion 6, it is possible to prevent some of the emulsion in the second cavity 21 from flowing out of the first end of the first cover portion 2. By providing the accommodating space 7, when the breast shield shakes, it is possible to provide movement space for the second cover portion 6, so that the second cover portion 6 can be firmly pressed against the breast, preventing the breast shield from detaching from the breast.

[0123] In one embodiment, as shown in FIG. 1 and FIG. 2 , the breast shield further includes a fixing portion, which protrudes from the inner wall of the suction nozzle portion 1 and extends along the circumference of the suction nozzle portion 1 to form an annular fixing portion 12 .

[0124] According to an embodiment of the present disclosure, the fixing portion can be provided on the inner wall of the mouthpiece 1 and can be annular. The number of annular fixing portions 12 and their location relative to the mouthpiece 1 can be selected and adjusted as needed. For example, one annular fixing portion 12 can be provided at the waist of the mouthpiece 1, or one annular fixing portion 12 can be provided near the milk outlet of the mouthpiece 1, or multiple annular fixing portions 12 can be provided at different locations on the nipple.

[0125] The protruding height of the annular fixing portion 12 can be selected and adjusted as needed to support the annular fixing portion 12 when the child sucks and prevent the nozzle portion 1 from being greatly deformed under the action of the child's sucking force.

[0126] According to the embodiment of the present disclosure, by providing the annular fixing portion 12 , when a child sucks on the mouthpiece 1 , it is possible to prevent the mouthpiece 1 from being greatly deformed, thereby preventing the outflow of milk from the milk outlet of the mouthpiece 1 .

[0127] In one embodiment, as shown in FIG1 and FIG2 , the breast shield further includes a diffuser 8 , which is connected to the first end of the first cover portion 2 . The wall thickness of the diffuser 8 is smaller than that of the first cover portion 2 , and the diffuser 8 is used to fit the breast.

[0128] According to an embodiment of the present disclosure, a diffuser portion 8 with a thinner wall is provided at the first end of the first covering portion 2. When the first covering portion 2 covers the breast, the diffuser portion 8 fits the breast, thereby further sealing the gap between the first covering portion 2 and the breast, thereby preventing the milk from flowing out through the gap.

[0129] The diffusion portion 8 can be an integrally formed structure with the first cover portion 2, or can be a separate structure. In one example, the diffusion portion 8 and the first cover portion 2 are an integrally formed latex product.

[0130] According to an embodiment of the present disclosure, by providing the diffusion portion 8 at the first end of the first shield portion 2, not only the contact area between the first shield portion 2 and the breast is increased, but also the gap between the first shield portion 2 and the breast can be further closed to prevent the milk from flowing out through the gap.

[0131] On the other hand, the shield in the related art is a thin-walled structure with a smooth inner surface. When used, the shield of the breast shield is easily not tightly fitted on the mother's breast, resulting in insufficient adsorption force of the breast shield on the breast and then falling off the mother's breast.

[0132] In order to solve the above-mentioned technical problems, an embodiment of the present disclosure provides a breast shield, comprising a first shield portion and a suction nozzle portion. The interior of the first shield portion has a second cavity for accommodating at least a portion of the breast, and the second end of the first shield portion is connected to the suction nozzle portion. A first protrusion is protruding from the inner side wall near the first end of the first shield portion, and the first protrusion extends along the circumference of the first shield portion, and the first protrusion is used to abut against the breast. Through any embodiment of the present disclosure, a negative pressure environment can be formed inside the first shield portion, so that the first shield portion can be firmly adsorbed on the breast, effectively solving the technical problem in the related art that the breast shield has insufficient adsorption force on the breast and thus falls off the mother's breast.

[0133] An embodiment of the present disclosure provides a breast shield, as shown in FIG6 , comprising a first shield portion 2 and a nozzle portion 1 .

[0134] The first covering portion 2 has a second cavity 21 therein for accommodating at least a portion of the breast, and a second end of the first covering portion 2 is connected to the suction nozzle 1 .

[0135] A first protrusion 5 is protruding from the inner side wall near the first end of the first covering portion 2 . The first protrusion 5 extends along the circumference of the first covering portion 2 . The first protrusion 5 is used to abut against the breast.

[0136] According to an embodiment of the present disclosure, the first covering portion 2 can be a structure for covering the breast, and the nozzle portion 1 can be a structure for covering the nipple. The two can be integrally formed. In other words, the nipple shield can be composed of the nozzle portion 1 for covering the nipple and the first covering portion 2 for covering the breast. The space inside the nozzle portion 1 for covering the nipple and the second cavity 21 of the first covering portion 2 for covering the breast together constitute the area of ​​the nipple shield.

[0137] The second end of the first cover portion 2 is connected to the mouthpiece 1 for the child to suck on. The end of the mouthpiece 1 has a connecting portion for discharging milk. The connecting portion can be configured as a closable structure. When the first cover portion 2 is placed on the breast, the connecting portion can remain closed to seal the second cavity 21. When the mouthpiece 1 is sucked, the second cavity 21 is connected to the external environment through the connecting portion. Choosing a closable connecting portion can prevent the negative pressure environment from being affected and milk from overflowing.

[0138] The first shield portion 2 can be provided in a variety of shapes and sizes. For example, three different sizes of first shield portions 2, large, medium, and small, can be provided to accommodate breasts of different sizes. Each first shield portion 2 can also be provided with a different size of the suction nozzle portion 1 to accommodate different nipple shapes and sizes.

[0139] The wall thickness of the first shielding portion 2 can be set in multiple sizes. If a thinner wall thickness is selected, its shape is easy to change and can better fit the breast. If a slightly thicker wall thickness is selected, when the first shielding portion 2 is deformed, it can gradually restore its original shape.

[0140] The first protrusion 5 can be set at any position on the inner sidewall of the first shield portion 2. For example, it can be set at the first end away from the suction nozzle 1, so that a relatively large negative pressure environment is formed in the second cavity 21 between the first protrusion 5, the breast, and the inner sidewall of the first shield portion 2. Alternatively, it can be set at the second end close to the suction nozzle 1, so that a relatively small negative pressure environment is formed in the second cavity 21 between the first protrusion 5, the breast, and the inner sidewall of the first shield portion 2. When the first protrusion 5 is confirmed, the air in the second cavity 21 is extracted by sucking on the suction nozzle 1, so that the air pressure in the second cavity 21 is lower than the air pressure of the external environment, forming a negative pressure environment. In this negative pressure environment, not only can the first shield portion 2 be firmly attached to the breast, but it can also generate further suction on the nipple, promoting the outflow of milk.

[0141] The first protrusion 5 can extend along the circumference of the first shield portion 2 in an arc-shaped structure or an annular structure. Optionally, as shown in FIG6 , the first protrusion 5 can also extend along the circumference of the first shield portion 2 in a ridge-shaped structure, with the height of the protrusion protruding from the inner sidewall of the first shield portion 2 being set to various levels to accommodate different breast needs.

[0142] The first protrusion 5 can protrude from the inner wall of the first cover portion 2, and the height of the protrusion from the inner wall can be adjusted according to actual conditions. It can be understood that if the first protrusion 5 is set at a lower height, the pressure of the negative pressure environment formed between it, the breast and the first cover portion 2 is relatively small, and it is difficult to adsorb the breast. If the first protrusion 5 is set at a higher height, the pressure of the negative pressure environment formed between it, the breast and the first cover portion 2 is relatively large, and the breast can be firmly adsorbed. However, if the height of the protrusion is too large, it will affect the close fit between the first protrusion 5 and the breast. Therefore, the wall thickness between one end of the first protrusion 5 protruding from the inner wall of the first cover portion 2 and the outer wall of the first cover portion 2 is not greater than 4.5 mm, for example 4 mm, 3 mm, etc., thereby providing a negative pressure environment of moderate pressure while also being able to fit closely with the breast.

[0143] The first cover portion 2, the suction nozzle portion 1 and the first protrusion 5 can be an integrally formed structure or can be a separate structure assembled together. In an optional embodiment, the first cover portion 2, the suction nozzle portion 1 and the first protrusion 5 are an integrally formed latex product, such as a liquid silicone product.

[0144] When using the breast shield, the breast shield is placed on the breast, the first end of the first shield portion 2 and the first protrusion 5 both rest against the breast, at least part of the breast is accommodated in the second cavity 21 inside the first shield portion 2, and the nipple is accommodated in the space inside the suction mouth portion 1, that is, the breast and the nipple are both accommodated in the accommodation space formed by the second cavity 21 and the space inside the suction mouth portion 1. When sucking on the suction mouth portion 1, the gas in the accommodation space will be discharged, making the air pressure in the accommodation space lower than the external ambient air pressure, thereby allowing the breast shield to be firmly attached to the breast. Alternatively, after the breast shield is placed on the breast, the breast shield is squeezed to deform it, so that the gas in the second cavity 21 of the accommodation space is discharged. After the squeezing is completed, as the breast shield recovers its shape, an environment lower than the external air pressure (i.e., a negative pressure environment) will be formed in the accommodation space, thereby allowing the breast shield to be firmly attached to the breast.

[0145] According to the embodiment of the present disclosure, by providing the first protrusion 5 on the inner side wall of the first covering portion 2, when the first covering portion 2 is covered on the breast, the first protrusion 5 abuts against the breast to close the gap between the first covering portion 2 and the breast. By sucking the suction nozzle 1, the air pressure in the accommodating space is lower than the air pressure of the external environment, so that a negative pressure environment is formed in the accommodating space, thereby making the first covering portion 2 firmly adsorbed on the breast, and preventing the breast shield from falling off the breast.

[0146] In one embodiment, as shown in Figures 7 and 8, a second protrusion 54 is protruding from the inner side wall of the first shield portion 2. The second protrusion 54 is located between the first protrusion 5 and the second end of the first shield portion 2, and the second protrusion 54 extends along the circumference of the first shield portion 2. The second protrusion 54 is used to abut against the breast.

[0147] According to an embodiment of the present disclosure, the second protrusion 54 can be arranged between the first protrusion 5 and the second end of the first shield portion 2. When the breast shield is placed on the breast, the second protrusion 54 and the first protrusion 5 both rest against the breast, and a negative pressure environment is formed in the accommodating space between the first protrusion 5, the second protrusion 54, the breast and the inner side wall of the first shield portion 2. Through this negative pressure environment, the breast shield of the present disclosure can be adsorbed on the breast, thereby increasing the adsorption force between the breast shield and the breast.

[0148] If the distance between the first protrusion 5 and the second protrusion 54 is too small, the suction force generated by the negative pressure environment formed between the second protrusion 54, the first protrusion 5, the breast and the inner wall of the first shielding part 2 will be too small, and the first shielding part 2 cannot be firmly adsorbed on the breast. Therefore, the distance between the second protrusion 54 and the first protrusion 5 is set to be greater than or equal to 8 mm, for example, 9 mm, 10 mm, etc.

[0149] The partial accommodating space between the second protrusion 54, the breast, the inner wall of the suction nozzle 1, and the inner wall of the first cover portion 2 is sucked by the suction nozzle 1 to extract air from the partial accommodating space, so that the air pressure in the partial accommodating space is lower than the air pressure of the external environment, thereby forming another negative pressure environment in the partial accommodating space. In this negative pressure environment, the first cover portion 2 can be more firmly adsorbed on the breast.

[0150] When the breast shield is placed on the breast, a negative pressure environment is formed in the accommodating space between the first protrusion 5, the second protrusion 54, the breast, and the inner sidewall of the first shield portion 2. Another negative pressure environment is also formed between the second protrusion 54, the breast, the inner sidewall of the suction nozzle portion 1, and the inner sidewall of the first shield portion 2. These are two independent negative pressure environments. In other words, two independent negative pressure environments can be formed inside the breast shield, so that the breast shield can be better adsorbed on the breast. Alternatively, when the other negative pressure environment formed between the second protrusion 54, the breast, the inner sidewall of the suction nozzle portion 1, and the inner sidewall of the first shield portion 2 leaks, the negative pressure environment formed between the first protrusion 5, the second protrusion 54, the breast, and the inner sidewall of the first shield portion 2 can still enable the breast shield to be firmly adsorbed on the breast.

[0151] The second raised portion 54 can extend along the circumference of the first shield portion 2 in an arcuate or annular configuration. Alternatively, as shown in FIG6 , the second raised portion 54 can extend along the circumference of the first shield portion 2 in a ridged configuration. The height of the second raised portion 54 protruding from the inner sidewall of the first shield portion 2 can be varied to accommodate different breast needs.

[0152] The second protrusion 54 can protrude from the inner wall of the first shield portion 2, and the height of the protrusion from the inner wall can be adjusted according to actual conditions. It can be understood that if a lower height second protrusion 54 is set, the adsorption force of the negative pressure environment formed between it, the first protrusion 5, the breast and the first shield portion 2 is relatively small, and it is difficult to adsorb the breast. If a higher height second protrusion 54 is set, the adsorption force of the negative pressure environment formed between it, the first protrusion 5, the breast and the first shield portion 2 is relatively large, and the breast can be firmly adsorbed. However, if the height of the protrusion is too large, it will affect the close fit between the second protrusion 54 and the breast. Therefore, the wall thickness between one end of the second protrusion 54 protruding from the inner wall of the first shield portion 2 and the outer wall of the first shield portion 2 is not greater than 4.5 mm, for example 4 mm, 3 mm, etc., thereby providing a negative pressure environment with moderate adsorption force and also close fit with the breast.

[0153] The first cover portion 2, the first raised portion 5, the second raised portion 54, and the suction nozzle portion 1 can be an integrally formed structure, or can be a separate structure assembled together. In one example, the first cover portion 2, the first raised portion 5, the second raised portion 54, and the suction nozzle portion 1 are an integrally formed latex product, such as a liquid silicone product.

[0154] According to the embodiment of the present disclosure, the first protrusion 5 and the second protrusion 54 are spaced apart on the inner wall of the first covering part 2. When the first covering part 2 covers the breast, the second protrusion 54 abuts against the breast to further close the gap between the first covering part 2 and the breast. By sucking the suction nozzle 1, the air pressure in the second cavity 21 between the second protrusion 54 and the first protrusion 5 is lower than the air pressure of the external environment, so that a negative pressure environment is formed in this part of the second cavity 21, further making the first covering part 2 firmly adsorbed on the breast, and preventing the breast shield from falling off the breast.

[0155] In one embodiment, as shown in FIG. 7 and FIG. 8 , the second protrusion 54 includes a first side wall 55 and a second side wall 56 connected to the inner side wall of the first covering portion 2 , and the first side wall 55 and the second side wall 56 are smoothly transitioned to each other.

[0156] According to an embodiment of the present disclosure, the second raised portion 54 may have a first side wall 55 arranged on a side opposite to the suction nozzle portion 1 and a second side wall 56 arranged on a side away from the suction nozzle portion 1, that is, one end of the first side wall 55 is connected to the inner side wall of the first shield portion 2 with a gap therebetween, and the other end of the first side wall 55 is smoothly transitioned to the other end of the second side wall 56, so that the second raised portion 54 can better fit the breast.

[0157] According to the embodiment of the present disclosure, by setting the end of the second protrusion 54 against the breast as a smooth transition structure, the mother's usage experience will be improved when it abuts the breast, and at the same time, it can better fit the breast to better seal the second cavity 21.

[0158] In one embodiment, as shown in FIG. 6 to FIG. 8 , the first protruding portion 5 includes a third side wall 51 and a fourth side wall 52 connected to the inner side wall of the first covering portion 2 , and the third side wall 51 and the fourth side wall 52 are smoothly connected.

[0159] According to an embodiment of the present disclosure, the first raised portion 5 may have a third side wall 51 arranged on a side opposite to the suction nozzle portion 1 and a fourth side wall 52 arranged on a side away from the suction nozzle portion 1, that is, one end of the third side wall 51 is connected to the inner side wall of the first shield portion 2 with a gap therebetween, and the other end of the third side wall 51 is smoothly transitioned to the other end of the fourth side wall 52, so that the first raised portion 5 can better fit the breast.

[0160] According to the embodiment of the present disclosure, by setting the end of the first protrusion 5 against the breast as a smooth transition structure, the mother's user experience will be improved when it is against the breast, and at the same time it can better fit the breast to better seal the second cavity 21.

[0161] In one embodiment, the second protrusion 54 is formed as an annular second protrusion along the circumference of the first covering portion 2 .

[0162] According to an embodiment of the present disclosure, the second protrusion 54 may extend along the circumference of the first covering portion 2 to form a closed structure, so as to better close the gap between the first covering portion 2 and the breast.

[0163] According to the embodiment of the present disclosure, by providing the annular second protrusion, the gap between the first shield portion 2 and the breast can be closed to prevent the milk from flowing out through the gap. At the same time, it can avoid affecting the negative pressure environment in the second cavity 21, so that the breast shield can be more firmly adsorbed on the breast.

[0164] In one embodiment, a slit is provided at one end of the nozzle portion 1 away from the first covering portion 2 , and the slit is used to connect the second cavity 21 with the external space of the second cavity 21 .

[0165] According to an embodiment of the present disclosure, the slit may be equivalent to the structure provided at the top of the nozzle portion 1 in Figures 6 to 8. When the nozzle portion 1 is sucked or the first cover portion 2 is squeezed, the air in the second cavity 21 will diffuse to the external environment. At this time, the slit is opened, the second cavity 21 is connected to the external environment, and the air in the second cavity 21 diffuses out. When the nozzle portion 1 is not subjected to force or the first cover portion 2 is not subjected to force, the slit is closed, completely sealing the second cavity 21. In one example, the slit may be an "I"-shaped slit, a "Y"-shaped slit, a "X"-shaped slit, a "V"-shaped slit, a "M"-shaped slit, etc.

[0166] According to the embodiment of the present disclosure, by providing a slit on the suction nozzle portion 1, the closed state of the second cavity 21 can be controlled. When the second cavity 21 reaches a negative pressure environment, this negative pressure environment can be maintained by the closed slit, so that the breast shield can be firmly adsorbed on the breast.

[0167] In one embodiment, the first protrusion 5 is formed as an annular first protrusion along the circumference of the first covering portion 2 .

[0168] According to an embodiment of the present disclosure, the first raised portion 5 can extend along the circumference of the first cover portion 2 as an annular first raised portion, or can extend along the edge of the first end of the first cover portion 2 as a closed first raised portion 5. That is to say, the annular shape of the first raised portion 5 can extend according to the edge of the first cover portion 2 to form a closed structure.

[0169] According to the embodiment of the present disclosure, by providing the annular first protrusion, the gap between the first shield portion 2 and the breast can be closed to prevent the milk from flowing out through the gap. At the same time, it can avoid affecting the negative pressure environment in the second cavity 21, so that the breast shield can be more firmly adsorbed on the breast.

[0170] In one embodiment, as shown in FIG. 7 and FIG. 8 , a fourth groove 53 is formed on the inner sidewall of the first covering portion 2 between the second protruding portion 54 and the first protruding portion 5 .

[0171] According to the embodiment of the present disclosure, since the second protrusion 54 is a protrusion structure, the first protrusion 5 arranged at intervals can also be a protrusion structure, then a fourth groove 53 is formed between the second protrusion 54 and the first protrusion 5, or, on the basis that the second protrusion 54 and the first protrusion 5 are both protrusion structures, the inner side wall of the first cover portion 2 located between the second protrusion 54 and the first protrusion 5 is simultaneously recessed in the direction away from the second cavity 21, so that the bending angle of the inner side wall of this interval is larger, thereby increasing the range of the negative pressure environment between the second protrusion 54, the first protrusion 5, the first cover portion 2 and the breast, and in this negative pressure environment, a greater adsorption force can be provided for the breast shield. However, if the bending angle of the inner wall of this interval is too large, the wall thickness of the first cover portion 2 in this interval is too thin, which will cause the first cover portion 2 in this area to deform and be unable to return to its original shape, but instead affect the negative pressure environment between the second protrusion 54, the first protrusion 5, the first cover portion 2 and the breast. Therefore, the wall thickness between the bottom of the fourth groove 53 and the outer wall of the first cover portion 2 is greater than or equal to 1.6 mm, and less than or equal to 4.5 mm, for example, 2.5 mm, 3 mm, etc. This not only increases the range of the negative pressure environment between the second protrusion 54, the first protrusion 5, the first cover portion 2 and the breast, thereby providing greater adsorption force for the breast shield, but also improves the toughness of the first cover portion 2 in this interval, so that the first cover portion 2 in this interval will not be easily deformed.

[0172] According to an embodiment of the present disclosure, by providing a fourth groove 53 between the second protrusion 54 and the first protrusion 5, the space between the second protrusion 54 and the first protrusion 5 can be increased, and under negative pressure conditions, a greater adsorption force can be provided for the breast shield to be adsorbed on the breast.

[0173] In one embodiment, as shown in FIG8 , the nipple shield may further include a diffusion portion 8 .

[0174] The diffusion portion 8 is connected to the first end of the first covering portion 2 . The wall thickness of the diffusion portion 8 is smaller than that of the first covering portion 2 . The diffusion portion 8 is used to fit the breast.

[0175] According to an embodiment of the present disclosure, a diffuser portion 8 with a relatively thin wall thickness may be provided at the first end of the first shield portion 2. When the first shield portion 2 covers the breast, the diffuser portion 8 fits the breast, thereby further sealing the gap between the first shield portion 2 and the breast, preventing the emulsion from flowing out through the gap. At the same time, the negative pressure environment in the first shield portion 2 can be stabilized, thereby increasing the adsorption force between the breast shield and the breast.

[0176] The diffusion portion 8 can be an integrally formed structure with the first cover portion 2, or can be a separate structure. In an optional embodiment, the diffusion portion 8 and the first cover portion 2 are an integrally formed latex product.

[0177] In one embodiment, the wall thickness of the diffusion portion 8 is greater than or equal to 0.2 mm and less than or equal to 0.6 mm, for example, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, etc. By providing a diffusion portion 8 with a thinner wall thickness, the toughness of the diffusion portion 8 can be reduced, so that it can better fit the breast.

[0178] According to the embodiment of the present disclosure, by providing the diffusion portion 8 at the first end of the first shield portion 2, not only the contact area between the first shield portion 2 and the breast is increased, but also the gap between the first shield portion 2 and the breast can be further closed to prevent the emulsion from flowing out through the gap, thereby stabilizing the negative pressure environment in the first shield portion 2 and increasing the adsorption force between the breast shield and the breast.
