Technical Field

[0001] This utility model relates to the field of maternal and infant products technology, and in particular to a milk bowl and a breast milk collector. Background Technology

[0002] Women who are breastfeeding often face the problem of leaking or spitting up breast milk. If the leaked breast milk is not collected in time, it will wet their clothes, causing discomfort and wasting breast milk. Therefore, a milk collector can be worn around the breast to collect the leaked breast milk promptly.

[0003] However, the suction between the collector and the breast is insufficient, resulting in a poor fit when worn. This lack of fit leads to leakage, wasting breast milk and potentially wetting the mother's clothes, causing discomfort. Utility Model Content

[0046] This utility model proposes a milk bowl.

[0047] Combination Figure 1 , Figure 5 as well as Figure 6 In one embodiment of the present invention, the milk bowl 20 forms a milk storage cavity 23 with an opening 24 for covering the nipple. The milk bowl 20 includes a flexible part 22 and a rigid part 21. The elastic modulus of the flexible part 22 is less than that of the rigid part 21, and the flexible part 22 is configured to reduce the volume of the milk storage cavity 23 by pressing and deforming to form a negative pressure adsorption.

[0048] In this embodiment, the milk bowl 20 is configured to include a flexible part 22 and a rigid part 21, wherein the elastic modulus of the flexible part 22 is less than that of the rigid part 21, and the elastic modulus of the flexible part 22 is 1 MPa-1 GPa; the elastic modulus of the rigid part 21 is greater than 10 GPa. For example, the flexible part 22 can be made of materials such as silicone or rubber. The flexible part 22 can deform when pressed, thereby reducing the volume of the milk storage cavity 23 and generating negative pressure, so that the milk bowl 20 can be tightly adhered to the surface of the breast. The rigid part 21 can be made of materials such as hard plastic or metal, providing reaction force support for the flexible part 22 to maintain the overall shape of the milk bowl 20.

[0049] Specifically, when the milk bowl 20 is placed over the breast, the opening 24 of the milk bowl 20 forms a ring seal between it and the breast. A milk outlet 12, connecting to the milk storage chamber 23, can be provided on the surface of the milk bowl 20, and a one-way valve can be installed at the milk outlet 12. When the operator presses the flexible part 22 of the milk bowl 20, the flexible part 22 indents inward, causing the volume of the milk storage chamber 23 to decrease, and internal air is discharged through the milk outlet 12. After the pressing stops, the flexible part 22 returns to its original shape due to the elasticity of the material. At this time, the volume of the milk storage chamber 23 increases compared to when it was pressed, but external air cannot flow back into the milk storage chamber 23, thus creating a negative pressure environment within the milk storage chamber 23. Of course, the milk outlet 12 and the one-way valve can be omitted. When breast milk needs to be collected, first press the flexible part 22 of the milk bowl 20. The flexible part 22 is concave so that the volume of the milk storage cavity 23 is smaller. Then, keep pressing the flexible part 22 and place the milk bowl 20 on the surface of the breast. After that, stop pressing the flexible part 22. The flexible part 22 returns to its original shape due to the elasticity of the material. At this time, the volume of the milk storage cavity 23 is larger than when it was pressed. However, the external air cannot flow back into the milk storage cavity 23. Therefore, a negative pressure environment is formed in the milk storage cavity 23.

[0050] The negative pressure acts on the surface of the breast through the milk storage chamber 23 and the opening 24, creating an adhesive force between the milk bowl 20 and the breast. The rigid part 21 restricts the overall deformation of the milk bowl 20 during pressing, ensuring that the deformation of the flexible part 22 is concentrated in a specific area, thus improving the structural stability of the milk bowl 20. Under the action of negative pressure, breast milk flows into the milk storage chamber 23 through the opening 24, causing any overflowing milk to flow back into the milk bowl 20.

[0051] Compared to related technologies, which rely on gravity to collect spilled milk naturally, this solution struggles to actively eliminate gaps between the breast and the device. This design generates negative pressure by pressing the flexible part 22, ensuring a better seal between the milk bowl 20 and the breast, reducing the likelihood of milk leakage from the contact surface. The negative pressure environment promotes rapid flow of breast milk into the milk storage chamber 23, minimizing milk residue on the skin surface. The rigid part 21, acting as a support structure, enhances the structural strength of the milk bowl 20 and extends its lifespan.

[0052] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the rigid part 21 is disposed around the outer periphery of the flexible part 22.

[0053] In this embodiment, the rigid part 21 wraps around the outer edge of the flexible part 22 in a ring-shaped structure to form a continuous constraint around the flexible part 22. When the flexible part 22 is subjected to external pressure, its outer periphery is restricted from outward expansion by the ring frame of the rigid part 21. Thus, the deformation of the flexible part 22 is guided to compress into the milk storage cavity 23, maximizing the volume change of the milk storage cavity 23. During the pressing process, the ring support structure of the rigid part 21 maintains the overall shape stability of the milk bowl 20, effectively preventing the flexible part 22 from local wrinkling or collapse due to unrestrained extension.

[0054] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present invention, in the wearing state, a flexible part 22 is provided in the lower middle area of ​​the surface of the milk bowl 20 opposite to the opening 24.

[0055] The flexible part 22 is located in the lower middle area of ​​the milk bowl 20. This "lower middle" refers to the vertical direction defined from the user's perspective when wearing the milk bowl 20. This ensures that the rigid part 21 covers as much as possible below the center of the milk bowl 20, meaning the thickest part of the milk bowl 20 corresponds as closely as possible to the rigid part 21. When the user wears the milk bowl 20 inside an underwear, the rigid part 21 supports the underwear, preventing the clothing from squeezing the flexible part 22 and causing deformation, which could lead to friction or pressure on the nipple. The lower middle area of ​​the milk bowl 20 corresponds to the flexible part 22. When the user wears the milk bowl 20, squeezing the flexible part 22 can expel air from the milk storage chamber 23, creating a negative pressure between the milk bowl 20 and the body. This ensures the milk bowl 20 adheres tightly to the body, preventing milk leakage.

[0056] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the milk bowl 20 includes at least two flexible parts 22, which are spaced apart.

[0057] In this embodiment, by providing at least two flexible portions 22, each of which can be pressed independently, the user can select the corresponding flexible portion 22 to press according to the shape of the breast or personal habits, thereby improving the user experience. Furthermore, the at least two flexible portions 22 are spaced apart, that is, the flexible portions 22 are separated by rigid portions 21 or non-deformable areas. Specifically, this can be achieved by providing alternating flexible and rigid areas on the surface of the milk bowl 20. This structure ensures that the deformation of each flexible portion 22 does not interfere with each other.

[0058] Combination Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the flexible part 22 and the rigid part 21 are integrally formed.

[0059] In this embodiment, the flexible part 22 and the rigid part 21 are seamlessly connected as a single unit through an integral molding process, which can be achieved using a two-color injection molding process or a co-extrusion molding process. The seamless connection between the flexible part 22 and the rigid part 21 avoids gaps or misalignments that may occur with separate assembly. When the flexible part 22 is subjected to external pressure, its elastic deformation is not affected by the displacement of the rigid part 21, resulting in a more uniform change in the internal volume of the milk storage cavity 23, thereby creating a stable negative pressure environment. Simultaneously, the rigid part 21 constrains the deformation range of the flexible part 22, effectively preventing excessive deformation that could lead to structural failure.

[0060] In other embodiments, the rigid part 21 and the flexible part 22 can be configured as separate structures and connected by means of plugging, snapping, etc. In order to improve the sealing effect, a sealing ring can be provided between the rigid part 21 and the flexible part 22 to improve the sealing effect between them.

[0061] Combination Figures 7 to 9 As shown, in one embodiment of the present invention, the flexible part 22 is provided at at least one end of both ends of the milk bowl 20;

[0062] Alternatively, the flexible part 22 may be provided on at least one side of both sides of the milk bowl 20;

[0063] Alternatively, the milk bowl 20 may include at least two spaced flexible portions 22, with flexible portions 22 provided at both the ends and sides of the milk bowl 20.

[0064] In one embodiment, the flexible part 22 may be provided as one and located at one of the two ends of the milk bowl 20. Alternatively, two flexible parts 22 may be provided and located at both ends of the milk bowl 20, respectively. It is understood that the ends of the milk bowl 20 refer to the upper and lower portions of the milk bowl 20 when the milk bowl 20 is in the wearing state, that is, corresponding to... Figure 7 The diagram shows the position of the flexible part 22. At this time, the user can press the upper and lower parts of the milk bowl 20 to collect breast milk.

[0065] In another embodiment, one flexible part 22 may be provided and located on one side of the two sides of the milk bowl 20, or two flexible parts 22 may be provided and located on both sides of the milk bowl 20 respectively. It can be understood that the sides of the milk bowl 20 refer to the left and right portions of the milk bowl 20 when the milk bowl 20 is in the wearing state, that is, corresponding to... Figure 8 The diagram shows the position of the flexible part 22. At this time, the user can press the left and right parts of the milk bowl 20 to collect breast milk.

[0066] In another embodiment, two flexible portions 22 may be provided, with one flexible portion 22 located at one end of the milk bowl 20 and the other flexible portion 22 located on one side of the milk bowl 20. Of course, as... Figure 9 As shown, four flexible parts 22 can also be provided, and respectively provided at both ends and both sides of the milk bowl 20.

[0067] This utility model also proposes a breast milk collector, which includes a flange 10 and a milk bowl 20. The specific structure of the milk bowl 20 is as described in the above embodiments. Since the breast milk collector adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0068] Among them, combined Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the flange 10 forms a nipple channel 11, one side of the flange 10 is used to fit against the breast, and the other side is connected to the milk bowl 20. The nipple channel 11 is connected to the opening 24.

[0069] In this embodiment, the flange 10 is an annular component with a nipple channel 11. At least one side of the flange 10 that conforms to the breast is made of a flexible material such as silicone or thermoplastic elastomer to ensure a tight fit and reduce air leakage. Simultaneously, the flexible side can adapt to changes in the curvature of the breast surface, further improving the sealing effect. The milk bowl 20 is connected to the flange 10 and serves as a milk storage chamber 2323 for storing milk. The milk bowl 20 and the flange 10 can be detachably connected or integrally formed. When collecting milk, the flange 10 is placed over the breast, at which point the nipple is embedded in or passes through the nipple channel 11 into the milk storage chamber 23, facilitating the timely collection of any overflowing milk into the milk storage chamber 23.

[0070] Combination Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the rigid part 21 is detachably connected to the flange 10.

[0071] In this embodiment, the connection method between the rigid part 21 and the flange 10 can be at least one of snap-fit, interference fit, threaded connection or magnetic connection.

[0072] In at least one embodiment, an elastic engagement can be achieved through a protrusion and groove structure between the rigid part 21 and the flange 10. Specifically, this can be achieved by using a ring-shaped buckle with barbs to engage with the corresponding groove 14, utilizing the locking force generated by the elastic deformation of the material to maintain the connection. Alternatively, the contact surface dimensions between the rigid part 21 and the flange 10 can be set to allow for a certain amount of interference, and the flange 10 can be made of a flexible material, forming a gapless interference fit structure through physical compression. A spiral pattern can also be provided between the rigid part 21 and the flange 10, specifically achieved by screwing an externally threaded pipe fitting with an internally threaded interface, generating axial clamping force through rotational movement. Magnetic elements can also be embedded in the contact surface between the rigid part 21 and the flange 10, specifically by combining neodymium iron boron magnets with magnetically conductive metal sheets, achieving rapid positioning and fixation through magnetic field adsorption.

[0073] In one embodiment of this utility model, for example Figure 2 and Figure 5 As shown, a hook 211 is provided extending toward the flange 10 from the rigid part 21. A groove 14 is formed in the side of the flange 10 that connects to the rigid part 21. The rigid part 21 and the flange 10 are connected by the engagement of the hook 211 and the groove 14.

[0074] The hooks 211 provided on the outer periphery of the rigid part 21 can be either elastic or rigid. It is understandable that, due to the certain length of the hooks 211, even rigid hooks 211 will deform under pressure during assembly. Furthermore, the part connecting the flange 10 to the rigid part 21 can be made of a flexible material to improve the ease of assembly when hooks 211 are engaged. After the hooks 211 enter the corresponding slots 14 of the flange 10, they return to their original shape, forming a mechanical lock between the hooks 211 and the slots 14. This process allows for quick assembly and disassembly with minimal tools.

[0075] Since both the rigid part 21 and the flange 10 are annular structures, the hook 211 and the groove 14 can also be configured to surround the outer periphery of the rigid part 21 and the flange 10. Thus, when the hook 211 and the groove 14 are engaged, the flange 10 and the rigid part 21 can form a uniform and stable engagement in the circumferential direction.

[0076] In one embodiment of this utility model, a sealing structure is provided at the connection between the flange 10 and the milk bowl 20. This sealing structure can be a rubber sealing ring, a silicone sealing gasket, or the like. When the flange 10 and the milk bowl 20 are detachably connected, the sealing structure between them improves the sealing effect, preventing air leakage from the milk storage chamber 23 during breast milk collection and thus improving the breast milk collection efficiency.

[0077] Combination Figure 1 and Figure 2As shown, in one embodiment of the present invention, the breast milk collector further includes a one-way valve 40, and a milk outlet 12 is provided on the surface of the flange 10 or the milk bowl 20. The one-way valve 40 is provided at the milk outlet 12 and is used to guide the fluid in the milk storage chamber 23 in one direction.

[0078] In this embodiment, the one-way valve 40 refers to a structure that allows fluid to flow in only one direction, such as a duckbill valve or a silicone diaphragm structure, which controls the opening and closing of the fluid channel through elastic deformation. The milk outlet 12 refers to an opening 24 provided on the surface of the flange 10 and communicating with the milk storage chamber 23, such as a circular or elliptical channel structure.

[0079] Specifically, during the collection of breast milk, by pressing the flexible part 22, the air inside the milk storage chamber 23 flows to the external environment through the one-way valve 40. When the pressing stops, the flexible part 22 returns to its original shape, and the one-way valve 40 remains closed to prevent air from flowing back into the milk storage chamber 23, thus creating a negative pressure environment inside the milk storage chamber 23.

[0080] In another embodiment, a one-way valve 40 and a milk outlet 12 are disposed on the milk bowl 20. When the flexible part 22 is pressed, air inside the milk storage chamber 23 can be discharged to the outside through the milk outlet 12 and the one-way valve 40 on the surface of the milk bowl 20. When the flexible part 22 is released, the one-way valve 40 can prevent external air from entering the milk storage chamber 23 to maintain a negative pressure environment. Of course, a sealing plug 30 and a soft rubber strip 50 can also be provided, with the sealing plug 30 connected to the milk bowl 20 through the soft rubber strip 50, and the one-way valve 40 disposed inside the sealing plug 30. For details, please refer to the description of the embodiment, which will not be elaborated further here.

[0081] In other embodiments, without the one-way valve 40 and the milk outlet 12, when the user needs to collect milk, they can first press the flexible part 22, which deforms to reduce the volume of the milk storage chamber 23, and then place the breast milk collector against the breast. At this time, the flexible part 22 is released and returns to its original shape, thus creating a negative pressure environment inside the milk storage chamber 23.

[0082] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the breast milk collector further includes a sealing plug 30, a one-way valve 40 is disposed inside the sealing plug 30, and the sealing plug 30 detachably seals the milk outlet 12.

[0083] In at least one embodiment, the sealing plug 30 is made of silicone or rubber, and its elastic deformation capability ensures a tight fit with the edge of the milk outlet 12 to seal the milk outlet 12. Alternatively, the sealing plug 30 can be configured as a rigid structure and interference-fitted with the flexible flange 10 to seal the milk outlet 12. When a negative pressure is formed inside the milk storage chamber 23, the sealing plug 30 makes tight contact with the inner wall of the milk outlet 12 through elastic deformation, effectively preventing breast milk leakage and backflow of external air; when milk needs to be expressed, the sealing plug 30 is separated from the milk outlet 12 after external force is applied, so that the milk stored in the milk storage chamber 23 can be poured out through the milk outlet 12. The sealing plug 30 and the inner wall of the milk outlet 12 can be detachably and stably connected by mechanical structures such as snap-fit, plug-in, or interference fit.

[0084] Combination Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the sealing plug 30 and the flange 10 are integrally formed by a soft rubber strip 50.

[0085] In this embodiment, the flexible rubber strip 50 is a strip-shaped connecting component made of flexible elastic materials such as silicone or thermoplastic elastomer. The flexible rubber strip 50 is molded simultaneously with the sealing plug 30 and the flange 10 through an injection molding process, forming an inseparable integral structure. By providing the flexible rubber strip 50, the sealing plug 30 can remain connected to the flange 10, reducing the possibility of the sealing plug 30 falling off or being lost.

[0086] Combination Figure 5 As shown, in one embodiment of the present invention, the surface of the sealing plug 30 is provided with a handle 31, which is a protrusion structure or a groove structure.

[0087] In this embodiment, the bump structure refers to a block-shaped structure that protrudes outward from the surface of the sealing plug 30. It can be in the shape of a hemisphere, cuboid, or cylinder to facilitate gripping and applying force by the fingers. The groove structure refers to a groove formed by the inward indentation of the surface of the sealing plug 30. It can be implemented by an arc-shaped concave surface, a straight groove, or a wavy concave structure to facilitate a stable force-applying contact surface between the fingers and the sealing plug 30.

[0088] Specifically, when it is necessary to remove the sealing plug 30, the user can press or hook the hand 31 with their fingers to obtain a fulcrum for applying force by using the raised part of the convex structure or the concave contour of the groove structure, thereby improving the convenience of removing the sealing plug 30.

[0089] Combination Figure 3 and Figure 4As shown, in one embodiment of the present invention, the flange 10 is provided with an air cushion 13 on the side for fitting the breast. The air cushion 13 is located on the outer periphery of the nipple channel 11, and the fitting surface size of the end of the air cushion 13 away from the nipple channel 11 is larger than the fitting surface size of the end of the air cushion 13 close to the nipple channel 11.

[0090] In some embodiments, the air cushion 13 is made of elastic materials such as medical-grade silicone or rubber, which can better conform to the breast and achieve a good seal. The air cushion 13 surrounds the outer periphery of the nipple channel 11, and the size of the contact surface between the air cushion 13 and the breast is designed to vary. This size variation can be gradual or non-gradual. For example, the contact surface between the air cushion 13 and the breast can be set as a frustum-shaped surface or a stepped surface. The reason for designing the contact surface size of the end of the air cushion 13 away from the nipple channel 11 to be larger than the contact surface size of the end closer to the nipple channel 11 is to make the contact surface of the air cushion 13 more adaptable to the shape of the breast, thereby increasing the contact area between the air cushion 13 and the breast, and thus improving the sealing effect between the air cushion 13 and the breast.

[0091] In one embodiment, the cross-sectional dimensions of the air cushion 13 are gradually increased in the direction away from the nipple channel 11. For example, the shape of the air cushion 13 can be petal-shaped or trumpet-shaped. This design can not only better fit the breast contour and ensure the seal between the flange 10 and the breast, effectively preventing air leakage and thus improving the efficiency of breast milk collection, but also buffer the pressure between the flange 10 and the breast, reducing the pressure on the breast during long-term use and providing a better user experience.

[0092] Specifically, in one embodiment, such as Figures 3 to 5 As shown, the air cushion 13 is shaped like a frustum, with the angle between its conical side and its axis ranging from 30° to 80°. Since the breast has a certain curvature and tilt angle, designing the air cushion 13 as a frustum, with the angle between its conical side and the axis within the range of 30° to 80°, allows the air cushion 13 to better conform to the breast, reducing gaps between the air cushion 13 and the breast, improving sealing. Simultaneously, this angle design helps to distribute suction more evenly, avoiding excessive or insufficient local pressure, and improving comfort during milk collection.

[0093] The hardness of the air cushion 13 is set between 20 and 40 on the Shore A scale. This hardness range ensures that the air cushion 13 has a certain degree of elasticity, which can better adapt to the shape of the breast, without being too hard and causing pressure on the breast. With the above settings, when the user uses the breast milk collector and presses the flexible part 22, the negative pressure generated is between 1KPa and 15KPa, which can effectively collect the overflowing milk, while also avoiding excessive negative pressure that would stimulate the breast to produce new milk.

[0094] In one embodiment, the flange 10 and the air cushion 13 are integrally molded. In this case, both the flange 10 and the air cushion 13 can be made of flexible materials and formed through a one-time molding process. Alternatively, the milk outlet 12 can be designed as a flexible material, and the flange 10 can be designed as a rigid plastic or other rigid material, forming an integral structure through a two-color molding process. Of course, in other embodiments, the flange 10 and the milk outlet 12 can also be detachably connected.

[0095] In another embodiment, the milk outlet 12 includes multiple fitting portions, which are spaced apart and arranged around the outer periphery of the nipple channel 11. The multiple fitting portions can be arranged symmetrically or asymmetrically around the outer periphery of the nipple channel 11. Specifically, the number of fitting portions can be 3, 6, 8, etc., and the shape of the fitting portions can be regular or irregular, such as triangle, trapezoid, frustum, semicircle, ellipse, etc., as long as the air cushion 13 can adhere to and fit the breast. No specific limitation is made here.

[0096] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
