[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 547,257, filed November 3, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to syringes and breastfeeding devices. More specifically, this disclosure relates to a nipple shield rinsing syringe, a nipple shield sterilization box, and a storage container for the nipple shield rinsing syringe and the nipple shield. Background Technology

[0004] Infant feeding devices such as nipple shields are frequently exposed to various liquids, such as breast milk or saliva. These devices have small openings and / or slits, where residual liquids can unintentionally remain. Typically, these devices are washed by hand with water or disinfectant after use. If not cleaned properly, residues of various liquids can remain in the openings and / or slits, leading to bacterial growth, discoloration, or a foul odor, rendering the device unsafe for infant use. Summary of the Invention

[0005] The following is a brief overview of this disclosure to provide a basic understanding of some aspects thereof. This overview is not an extensive summary of the various embodiments of this disclosure. It is neither intended to identify key or essential elements of this disclosure nor to depict any scope of this disclosure. The sole purpose of this overview is to present some concepts in a simplified form as a prelude to a more detailed explanation later.

[0006] This disclosure describes a flushing injector having a barrel and a plunger. The barrel has a closed first end and an open second end. The closed first end is formed as a terminal with an outlet. The wall of the barrel at the terminal has a substantially flat surface that extends radially outward into a concentric cylindrical protrusion. The wall then slightly tapers inward and extends outward and downward from the concentric cylindrical protrusion to a terminal base. The wall continues to extend downward from the terminal base in a uniform diameter and cylindrical shape to the open second end. The barrel defines a reservoir suitable for storing fluid, which is defined by the terminal and the barrel. The plunger has a column and a plug fixed to the column. The plug has a mating flat surface and a mating concentric protrusion, suitable for fitting into the substantially flat surface of the barrel and the interior of the concentric cylindrical protrusion. When the plunger is pushed toward the terminal of the barrel into the open second end, the plug is configured to engage sealingly with the wall of the barrel and forcefully dispensing the fluid stored in the reservoir outward through the outlet. The flushing syringe can be used with fitting devices such as nipple shields to clean or disinfect nipple shields.

[0007] This disclosure also describes the use of a flushing syringe with a sterilization box. The sterilization box has a body having a peripheral wall surrounding a base. The base has a reservoir for holding fluid. The base also has a protrusion extending upward from within the reservoir by a predetermined distance. The protrusion has at least one channel therein through which fluid can flow upward. The sterilization box also has a lid attached to the body, adapted to cover the body.

[0008] Furthermore, this disclosure describes the use of nipple shields and irrigation syringes with a sterilization storage box. The sterilization storage box has a body with a peripheral wall surrounding a base. The base is divided into an upper base portion and a lower base portion. The upper base portion surrounds a reservoir for holding fluid. The upper base portion also has a protrusion extending upwards from within the reservoir by a predetermined distance.

[0080] This disclosure is described in conjunction with the accompanying drawings, wherein like reference numerals are used to refer to the same elements throughout. In the following description, numerous specific details are set forth for purposes of explanation to provide a thorough understanding of this disclosure. However, it will be apparent that this disclosure can be practiced without these specific details. Exemplary embodiments of the flushing syringe will now be described in more detail with reference to the accompanying drawings.

[0081] Figure 1-4A flushing syringe 10 is shown, having a barrel 16 and a plunger 40. The barrel 16 has a closed first end 12 and an open second end 14, wherein the closed first end 12 forms an end 24 with an outlet 18. The wall 36 of the barrel 16 at the end 24 has a substantially flat surface 30 that extends radially outward into a concentric barrel protrusion 34, which serves as an outwardly projecting lip having a rounded edge and expanding outward from the top surface. The wall 36 then slightly tapers inward from the concentric barrel protrusion 34 and then extends downward and outward from the concentric barrel protrusion 34 to the end base 32. See [link to more detailed view of the outwardly projecting lip 34] Figures 17A-17B Then, wall 36 extends downward from the end base 32 in a uniform diameter and cylindrical shape to the open second end 14. The cylinder 16 is a single, uniform component consisting of walls of substantially uniform size and thickness, and defines an area suitable for storing fluid 85, defined by end 24, cylinder 16, and plunger 40. Figure 15 ) storage chamber 22.

[0082] It should be understood that the distal end 24 may have alternative embodiments with various shapes, such as, but not limited to, frustoconical, dome-shaped, triangular, square, or equivalent shapes, to fulfill the function described in the flushing syringe 10 of this disclosure. For example, the distal end 24 may be hermetically fitted to a mating device that requires a triangular shape to ensure proper fit and seal.

[0083] Furthermore, it should be understood that the outlet 18 may be centered or offset within the end 24 and includes at least one orifice adapted to dispense fluid 85 through the end 24 of the barrel 16 as shown and described in the flushing syringe 10 of this disclosure. For example, the end 24 may have a plurality of outlets 18 disposed on a substantially flat surface 30, or a single outlet 18 eccentric with respect to the end 24, to control the volumetric flow rate of fluid 85 released from the reservoir through the outlet 18.

[0084] The rinsing syringe 10 may have a splash guard 28 extending radially outward from the distal base 32 for a predetermined length. The splash guard 28 can be used by the user when inserting the distal end 24 into a mating device (e.g., a nipple shield 60, see below). Figure 16The lever flange is held in conjunction with (17). For example, the user can use the splash guard 28 to hold their index finger and press the nipple shield 60 with their thumb or other hand. The splash guard 28 can also trap or deflect escaping fluid 85 away from the user's hand when the tip 24 mates with the mating device and forms an improper seal. In addition, the splash guard 28 can serve as a visual indicator to tell the user how deep the tip 24 should be inserted into the mating device. For example, when the flushing syringe 10 is inserted into a mating device such as the nipple shield 60, the user places the nipple shield 60 on the tip 24 and presses the nipple shield 60 against the tip 24 so that the base of the nipple shield 60 is aligned with the splash guard 28. The user can visually utilize the gradually decreasing distance between the splash guard 28 and the nipple shield 60 until the maximum insertion depth of the tip 24 is reached. By acting as a visual indicator, the splash guard 28 ensures a strong seal is formed between the tip 24 and the mating device.

[0085] like Figure 17A as well as Figure 17B As best shown in the magnified detail of part AA, a seal is established between the end 24 and the mating device due to slight deformation caused by the pressure fit between the mating device, such as the nipple shield 60, and the concentric cylindrical protrusion 34. The extended circular edge 34 serves as a lip, with a diameter larger than the diameter of the surface 34B immediately below the circular lip portion 34. Therefore, the concentric cylindrical protrusion 34 is configured with a diameter slightly larger than the inner diameter of the mating device, such that when the concentric cylindrical protrusion 34 is inserted into the mating device, the surface of the mating device deforms slightly, thereby forming a seal. It should be understood that the material of the extended circular lip 34 is of an elastic type, allowing for temporary, slight deformation, such as, but not limited to, silicone, rubber, or any other alternative elastic material capable of achieving the features described in this disclosure. By making the mating device constructed of an elastic material, a proper seal between the end 24 and the mating device is ensured. For example, if the user places the mating device on the end 24 in a manner that is not perpendicularly aligned with the end 24, a seal can still be formed between the outer surface of the concentric cylindrical protrusion 34 and the surface of the mating device because the configured diameter can still undergo slight deformation, thereby sealing the connection.

[0086] The reservoir 22 is surrounded by a wall 36 having a continuous, uniform, and predetermined thickness, capable of adequately withstanding the dispensing pressure caused by the plunger 40 being pressed within the cylinder 16 during cleaning or rinsing of the mating device as described in this disclosure. The interior of the wall 36 extends upward in a uniform diameter and cylindrical shape from the open second end 14 to the end base 32. The interior of the wall 36 then tapers inward and upward to the inner concentric cylindrical protrusion 35. The interior of the wall 36 then tapers radially inward from the inner concentric cylindrical protrusion 35 to a substantially flat inner surface 31 for mating with the plug 42, which is described in more detail below. An outlet 18 perforates through the closed first end 12 to connect the reservoir 22 to the atmosphere, thereby allowing fluid 85 to be forcibly expelled from the reservoir 22 when the plunger 40 is pressed into the cylinder 16. See also Figure 16-1 7.

[0087] The volumetric capacity of the reservoir 22 may vary, for example, but not limited to: 10 ml, 20 ml, or any suitable volumetric measurement capable of holding fluid 85 and achieving the features and properties described in this disclosure, such as a washing, cleaning, or rinsing fitting (e.g., nipple shield 60).

[0088] The material properties of the cylinder 16 may vary, including but not limited to: silicone, plastic, glass, metal, rubber, or any suitable material capable of withstanding the dispensing pressure when the plunger 40 is pressed into the cylinder 16 to flush, wash or clean the mating device as described in this disclosure.

[0089] It should be understood that the barrel 16 is typically a single component; however, in alternative embodiments, the barrel 16 may be composed of multiple components joined together. For example, in an alternative embodiment, the end 24 may be engaged with a cylindrical container to form the barrel 16. The multiple components may be joined by a variety of different methods, including but not limited to: adhesive, friction fit, fastening, or suitable methods capable of combining the multiple components such that, when combined, they can withstand the dispensing pressures as described in this disclosure when the flushing syringe 10 is used with the plunger 40 to flush, wash, or clean the mating device. Allowing the barrel 16 to be made of multiple components allows the end 24 to have different material properties than the cylindrical container 20.

[0090] Different material properties of the tip 24 can provide a better fit with a mating device, such as a nipple shield 60, and the cylindrical container can be made of different materials. For example, if the mating device of, for example, the nipple shield 60 is made of silicone, a glass tip 24 can provide a better seal, while a cylindrical container made of plastic can have higher performance and better withstand the pressure associated with washing, rinsing, or cleaning the mating device. Furthermore, the cylinder 16, made of multiple components, allows the tip 24 to be interchangeable with alternative embodiments and / or used for secondary purposes. For example, in one case, the tip 24 can be a truncated cone shape to fit with the nipple shield 60. In a second case, the tip 24 can be interchangeable with alternative embodiments for secondary use with different mating devices, such as cleaning baby bottle nipples.

[0091] The barrel 16 may have a barrel flange 58. The barrel flange 58 extends outwardly for a predetermined length from both sides of the open second end 14. The barrel flange 58 may be expanded upward at a predetermined angle to form recesses 74A, 74B. For example, when holding the flushing syringe 10, the user may fix or rest their index and middle fingers on the recesses 74A, 74B respectively, so as to use the barrel flange 58 to abut against the plunger 40.

[0092] Figure 5 and Figure 6 A plunger 40 is shown, having a plunger 44 and a plug 42 fixed to the plunger 44. The plug 42 has a flat surface 78 and a concentric plug protrusion 79, adapted to mate with the substantially flat inner surface 31 and the inner concentric cylinder protrusion 34 of the cylinder 16. Figure 9 As shown, when the plunger 40 is pushed toward the open second end 14 of the cylinder 16 toward the end 24, the plug 42 seals against the wall 36 and forcibly dispenses fluid 85 through the outlet 18, see also Figure 17.

[0093] Figure 5-12The plug 42 is shown to be removably secured to the post 44. Various different securing methods can be used to attach the plug 42, such as, but not limited to, fastening, friction fitting, bonding, or equivalent securing methods capable of withstanding the pressures associated with the application of the flushing syringe 10 described herein. By allowing the plug 42 to be removably secured to the post 44, the plug 42 can be interchanged for easy replacement. For example, the plug 42 may no longer form a proper seal with the wall 36 of the barrel 16 due to prolonged use, but the post 44 may still be in good condition. In this case, the plug 42 can be interchanged with a new plug to allow the flushing syringe 10 to continue to be used. Furthermore, the shape of the plug 42 can vary, such as, but not limited to, dome-shaped, frustoconical, square, or any suitable shape capable of forming a proper seal with the wall 36 of the barrel 16 as described herein. It should be understood that, in alternative embodiments, the plug 42 can be permanently secured to the post 44 by one of a variety of different joining methods, such as, but not limited to, molding, die casting, bonding, or any suitable method capable of sealing the plug 42 to the post 44.

[0094] Figure 7-10 The flat surface 78 of the plug 42 extends radially outward to form a concentric plug protrusion 79. The plug 42 then slightly tapers inward from the concentric plug protrusion 79, and then extends outward and downward from the concentric plug protrusion 79 to the middle portion 50 of the plug. This structure is similar to and substantially parallel to the external structure of the top of the closed end 12 and the lip protrusion 34. The plug 42 then extends downward from the middle portion 50 in a uniform diameter and cylindrical shape to the lower portion 52 of the plug. The plug 42 then tapers radially inward from the lower portion 52, and then extends downward in a uniform diameter and cylindrical shape to the base 54 of the plug.

[0095] The plug 42 has a plurality of annular protrusions 70 disposed between the plug middle portion 50 and the plug base portion 54. In this embodiment, at least one of the plurality of annular protrusions 70 is located at the plug lower portion 52, and at least one of the plurality of annular protrusions 70 is located at the plug base portion 54.

[0096] like Figure 9As shown, the plunger 40 is configured to fit within the cylinder 16 such that the plunger 44 does not contact the interior of the wall 36. A plurality of annular protrusions 70 on the plug 42 are configured with a diameter slightly larger than the diameter of the plug's middle portion 50 and lower portion 52. The diameter of the plurality of annular protrusions 70 is also slightly larger than the inner diameter of the wall 36 forming the reservoir 22, causing the plurality of annular protrusions 70 to slightly deform, thereby forming a seal with the interior of the wall 36 of the cylinder 16. For example, when the plunger 40 is inserted into the cylinder 16, the plurality of annular protrusions 70 form a seal with the wall 36 due to their different diameters, preventing fluid 85 (see FIG. 17) from escaping rearward through the closed first end 12 of the cylinder 16 from the reservoir 22. The plurality of annular protrusions 70 have a diameter slightly larger than the inner diameter of the wall 36, and the annular protrusions 70 may bend inward and / or outward upon contact with the wall 36. Therefore, the static friction formed between the plurality of annular protrusions 70 and the wall 36 is reduced by the inward / outward bending of the plurality of protrusions 70, thereby allowing the plunger 40 to move through the cylinder 16 without breaking the seal formed between the plurality of annular protrusions 70 and the wall 36. Furthermore, the seal formed between the plurality of annular protrusions 70 and the wall 36 can serve as a guide when the plunger 40 is inserted into the cylinder 16. For example, when the plunger 40 is inserted into the cylinder 16, the size of the plunger 44 is smaller than the diameter of the wall 36 to allow the plunger 40 to move; however, if the spatial gap formed by the diameter difference is too large, the plunger 44 may have a tendency to move in the horizontal direction. Therefore, the plurality of annular protrusions 70 can serve as a guide, restricting horizontal movement due to the seal formed with the wall 36, and facilitating movement in the vertical unilateral direction.

[0097] The material properties that may be used for the plug 42 and the plurality of annular protrusions 70 may vary, including but not limited to: silicone, rubber or any suitable flexible material as described in this disclosure that can withstand the pressure of the plunger 40 being pressed within the cylinder 16 and allow slight deformation of the plurality of annular protrusions 70.

[0098] Figure 10 An exemplary configuration of the plug 42 is shown. A blind face 76 may be centrally located within the plug 42. The blind face 76 extends upward from the plug base 54 and then laterally outward to form an inner circular edge 77. The blind face 76 then extends radially inward from the inner circular edge 77, thus having a substantially flat plug surface 81. The blind face 76 is configured to receive the end 48 of the column shaft 45, see [reference needed]. Figure 9 and 12 .

[0099] like Figure 11AAs shown in Figure -B, the plug base 54 has a centrally located orifice 56 to allow the post tip 48 to be removably secured to the plug 42. For example, the post tip 48 can be inserted through the orifice 56 and press-fitted into a blind hole 76. The shape of the orifice 56 generally conforms to the post rib 98, allowing the post tip 48 to be received within the blind hole 76. The orifice 56 can take various shapes, such as, but not limited to, a cross shape or any shape as described in the flushing syringe 10 of this disclosure, capable of properly securing the post tip 48 into the blind hole 76. The blind hole 76 is configured to receive the post tip 48 such that the plug base 54 communicates with the locking recess 64 of the post 40, see [reference needed]. Figure 5 The end of the column 48 is securely set at the blind spot 76. Figure 12 The locking notch 64 is between the two. The locking notch 64 ensures that the plug 42 does not separate from the post 44 and keeps the post end 48 compressed with the blind hole 76.

[0100] Figure 12 The column 44 is shown to have a column end 48 that extends radially outward to a rounded edge 62. In a cross-section of the column 44 transverse to its axial length A, the column 44 is constructed in a cross shape, with each column rib 98 being a cross-shaped leg. The column end 48 is attached at one end to a column rib 98. It should be understood that the column 44 may have alternative embodiments, such as, but not limited to, a solid cylindrical core or any suitable shape capable of achieving the features and properties described in the flushing syringe 10 of this disclosure. The column 44 then extends axially downward from the rounded edge 62 to a locking recess 64. The column ribs 98 then extend outward and axially downward from the locking recess 64 to a column base 49.

[0101] The column base 49 may extend outward on both sides to form a base flange 51, see also Figure 1 , 3 And 4. When the plunger 40 is pressed into the cylinder 16, the base flange 51 can be used as a lever for the user. For example, the base flange 51 can provide the user with a larger surface area available when pressing the plunger 40 with their thumb. Figure 13 and 14 As shown, the barrel flange 58 may extend outwards on both sides beyond the base flange 51 to increase user comfort when holding the flushing syringe 10. For example, a shorter base flange 51 may contribute to greater comfort when the user holds the flushing syringe 10 with their index finger in the recesses 74A-B and their thumb on the base flange 51. It should be understood that the base flange 58 may have alternative embodiments, such as, but not limited to, extending outwards by the same distance, a greater distance, or any other suitable length that provides leverage for the user when applying compressive force to the plunger 40 as described in this disclosure. The plunger base 49 may also have a protrusion 86 as an additional gripping portion for the user's thumb. For example, the protrusion 86 may prevent the user's thumb from slipping off the plunger base 49 when the plunger 40 is pressed into the barrel 16.

[0102] Various materials that may be considered for use in column 44 may include, but are not limited to: silicone, plastic, glass, metal, rubber, synthetic materials and / or any suitable material capable of achieving the features and properties described in the flushing syringe 10 of this disclosure.

[0103] refer to Figure 16 and Figure 12 Full level indicators 66 are evenly and radially disposed at predetermined positions on the column rib 98 between the locking recess 64 and the column base 49. The position of the full level indicators 66 depends on the predetermined volumetric capacity of the reservoir 22. For example, if the volumetric capacity of the reservoir is 10 or 20 ml, the full level indicators 66 are positioned higher or lower respectively to inform the user of the maximum amount of fluid 85 that the reservoir 22 can hold. The full level indicators 66 are defined by recessed cutouts. The full level indicators 66 may have alternative constructions, such as, but not limited to, rectangular cutouts, triangular cutouts, printed line indicators, or any other construction that can serve as a visual indicator capable of achieving the features described herein. Figure 16 As shown, the full level indicator 66 is configured such that when the plunger is withdrawn from the cylinder 16, the midplane of the full level indicator 66 is coplanar with the open second end 14, thereby indicating the predetermined volume capacity within the reservoir 22. For example, when the midplane of the full level indicator 66 is coplanar with the open second end 14, the reservoir 22 has reached its volume capacity.

[0104] Figure 15-18 The flushing syringe 10 in use is shown. Figure 15 The cylinder filling step (“BFS”) is shown. Figure 17A The fluid distribution step (“FDS”) is illustrated. In the BFS, the plunger 40 is pulled out of the cylinder 16 by a first external force 87. In the FDS, the plunger 40 is pressed into the cylinder 16 by a second external force 88, such that the substantially flat plug surface 81 of the plug 42 mates with the substantially flat inner surface 31 of the cylinder 16.

[0105] Figure 15A flushing syringe 10 is shown in a BFS (Body Fluid Setter) that receives fluid 85 to be contained in a reservoir 22. The flushing syringe 10 receives fluid 85 by placing its tip 24 into the fluid 85, which can be drawn from a basin 90 as shown. A first external force 87 is applied to the plunger 40 while the tip 24 is held within the fluid 85. By applying the first external force 87 to the plunger 40, a negative pressure is created within the reservoir 22, causing fluid 85 to enter the reservoir 22. As the plunger 40 is withdrawn from the barrel 16 by the first external force 87, the empty space within the reservoir 22 is filled with fluid 85. It should be understood that the flushing syringe 10 is not limited to use with a basin 90 to engage fluid 85. The flushing syringe 10 can be used, but is not limited to, with containers, faucets, or other suitable liquid sources as described in this disclosure for containing fluid 85.

[0106] Figure 16 A flushing syringe 10, filled via a BFS and mated with a nipple shield 60, is shown. It should be understood that the flushing syringe 10 can be used with a variety of mating devices and is not limited to the nipple shield 60. In alternative embodiments, the flushing syringe 10 can be used, but is not limited to: feeding an infant with a source of nutrient fluid, flushing a breast pump hose, flushing portable breast pump components, flushing a baby bottle, flushing a baby bottle nipple, flushing a straw, flushing an anti-spill cup assembly, flushing a nasal suction device, flushing an ear cleaning device, flushing an anti-colic device, serving as a breast mold syringe, or other related equipment and functions.

[0107] Figure 17A and 18 A flushing syringe in an FDS is shown, discharging fluid 85 from reservoir 22 through various channels in nipple shield 60. After reservoir 22 is filled with fluid 85, fluid 85 is forcibly expelled from reservoir 22 by plunger 40 when a second external force 88 is applied to plunger 40. Plug 42 engages with fluid 85, thereby transmitting the compressive force applied by the second external force 88. Together with a plurality of annular protrusions 70 forming a seal with wall 36, fluid 85 is forcibly propelled through outlet 18 and into channels in nipple shield 60 at a velocity corresponding to the second external force 88 applied by the user.

[0108] It should be understood that the fluid 85 stored in the reservoir 22 may consist of various fluids, such as, but not limited to, water, disinfectant, molding liquid and / or any suitable liquid that can clean, clean, rinse and withstand the applied pressure when the plunger 40 is pressed in the cylinder 16 to force the fluid 85 onto the mating device (e.g., nipple shield 60).

[0109] like Figure 17AAs shown, the flushing syringe 10 is press-fitted with the nipple shield 60. The concentric cylindrical protrusion 34 at the end 24 engages with the inner surface 110 of the protrusion 106 of the nipple shield 60 to form a flushing chamber 92. The concentric cylindrical protrusion 34 is configured such that the outer periphery of the concentric cylindrical protrusion 34 complements the raised or dome-shaped inner surface 110 of the protrusion 106 to form a seal, thereby securing the nipple shield 60 to the end 24 of the flushing syringe 10.

[0110] During FDS, when a second external force 88 is applied to the plunger 40, fluid 85 is propelled through the outlet 18 of the end 24 into the flushing chamber 92. The secure fit between the nipple shield 60 and the end 24 ensures that fluid 85 subsequently flows in and through the fluid channel 114 and out through the multiple openings 116 on the outer surface 112. As fluid 85 flows through the fluid channel 114 and out through the multiple openings 116, the fluid channel 114 is effectively cleaned. The flow of fluid 85 within the fluid channel 114 displaces any debris left by the use of the nipple shield 60. For example, when using the nipple shield 60 during breastfeeding, breast milk may remain within the fluid channel 114, and the flushing syringe 10 can then be secured to clean the nipple shield 60, thereby reducing the chance of bacterial growth within the fluid channel 114.

[0111] Furthermore, if an improper seal is formed between the concentric barrel protrusion 34 and the nipple shield 60, the splash guard 28 can prevent fluid 85 from escaping from the flushing chamber 92 and splashing onto the user. For example, if an improper seal is formed between the nipple shield 60 and the concentric barrel protrusion 34 due to improper placement, the splash guard 28 can deflect any escaping fluid away from the user's hand. Additionally, the splash guard 28 can be utilized by the user when the flushing syringe 10 is used with the nipple shield 60. The splash guard 28 can ensure a proper seal between the nipple shield 60 and the end 24 by acting as a guide for the nipple shield 60. For example, the user of the nipple shield 60 can place two fingers on the outer surface 112 of the nipple shield 60 and their thumb under the splash guard 28, so that when the user presses the nipple shield 60 down onto the end 24, the concentric barrel protrusion 34 and the inner surface 110 of the nipple shield 60 are firmly engaged. In an alternative embodiment, the splash shield 28 may also abut against the nipple shield 60, thereby forming a second seal between the inner surface 110 of the nipple shield 60 and the splash shield 28.

[0112] Figure 19 and 20A nipple shield 60 is shown, having a base 104, a protrusion 106, and a translucent flow indicator 108. The base 104 is configured to cover at least a portion of the user's breast. The base 104 has an inner surface 110 and an outer surface 112. The protrusion 106 has a nipple-like shape and is recessed upward from the base 104. The protrusion 106 is substantially centrally located at the base 104, and the translucent flow indicator 108 is located away from the protrusion 106. The translucent flow indicator 108 is defined by a fluid channel 114 connecting the inner surface 110 of the protrusion 106 to a plurality of openings 116 on the outer surface 112 located at the crown 118 of the protrusion 106.

[0113] Figure 21A and 21B A translucent flow indicator 108 is shown, starting from a protrusion 106 and extending out of the protrusion 106 to a plurality of openings 116, so that when the nipple shield 60 is in use, the breast milk from the user can be seen circulating through the translucent flow indicator 108. The nipple shield 60 is made of a translucent flexible material so that when the nipple shield 60 is in use, the breast milk can be visually seen flowing through the fluid channels 114. For example, in Figure 21B In this design, nipple shield 60 is placed on the breast during breastfeeding, and when the baby 120 suckles, breast milk can be seen flowing from the breast through fluid channel 114 and into the baby's mouth. A translucent flow indicator 108 serves as a visual aid for the breastfeeding mother and provides the benefit of knowing that her baby is receiving breast milk.

[0114] Figure 22-25 A sterilization box 140 is shown. The nipple shield 60 can also be cleaned using the sterilization box 140. The sterilization box 140 has a lid 142, which is hingedly attached to the box body 144 via a box hinge 146. Figure 23 As shown in the top view, the cover 142 has an egg-shaped exterior capable of surrounding the nipple shield 60. From the hinge 146, the cover 142 projects radially outward and downward evenly, then curves inward to the cover end 148. It should be understood that the cover 142 may have alternative shapes, such as, but not limited to, dome-shaped, rectangular, triangular, or any other suitable shape capable of covering the nipple shield 60 of this disclosure. From the cover end 148, the cover 142 extends radially downward into finger-like tabs 150. Figure 27A , 27B As shown in Figure 31, the cover 142 has an interior with a hollow profile, configured to accommodate the nipple shield 60.

[0115] like Figure 26 , 27AAs shown in Figure 27B, the finger-like protrusion 150 extends outward away from the cover 142. The purpose of this outward extension is to provide the user with a lever to grasp the finger-like protrusion 150. A locking aperture 152 is centrally positioned on the finger-like protrusion 150. The locking aperture 152 is configured to receive a locking protrusion 154. The locking aperture 152 and the locking protrusion 154 together form a box lock 156. When the cover 142 is hinged closed onto the box body, the finger-like protrusion 150 presses against the locking protrusion 154, causing the locking protrusion 154 to be received within the locking aperture 152, thereby securing the cover 142 to the box body 144. The user can then use the finger-like protrusion 150 to lift the cover from the locking protrusion 154, thereby opening the sterilization box 140. It should be understood that the box lock 156 may have alternative implementations, such as, but not limited to, magnetic locks, locking notches, snaps, or any other suitable locking mechanism capable of securing the cover 142 to the box body 144 of this disclosure.

[0116] like Figure 26 , 27A As shown in Figure 27B, the housing 144 extends radially outward and downward uniformly from the hinge 146, then curves inward to the housing end 158. The upper periphery of the housing 144 also has a recessed edge 160 that extends downward around the periphery of the housing from a substantially flat section 186 formed by the portion of the housing 144 formed by the hinge 146 and the upper portion of the housing 144 to the housing end 158. At the housing end 158, the recessed edge 160 extends radially downward to form a finger-shaped tab recess 184 configured to receive a finger-shaped tab 150. A locking protrusion 154 is thus centrally positioned within the finger-shaped tab recess 184. The recessed edge 160 is configured to receive a mating lip 162 located on the outer periphery of the cover 142, which extends around the cover 142 from the hinge 146 and extends into the finger-shaped tab 150. Furthermore, at least one notch 188 is present adjacent to the hinge 146. When the lid 142 is hinged closed on the housing 144, the recessed edge 160 and the mating lip 162 form a partial seal. Additionally, a substantially flat section 186 and at least one notch 188 form a vent 190. The vent 190 allows generated steam to escape from the sterilizer 140 during use, thus reducing its pressure. For example, once a partial seal is formed between the lid 142 and the housing 144, the pressure increases as the temperature of the sterilizer 140 rises to generate steam, necessitating pressure reduction, which the vent 190 enables. The vent 190 also functions as a pouring spout, allowing fluid 85 within the housing 144 to be poured out without opening the sterilizer 140.

[0117] Figure 28The box body 144 extends evenly downwards from the box hinge 146 to the box body leg 164A. From the box body leg 164A, the box body 144 then extends outwardly in a projecting manner to form another box body leg 164B located at the box body end 158. As shown... Figure 31 As shown, the purpose of the protruding extension of the box body 144 is to form an arched support 174 inside the box body 144 to accommodate the nipple shield 60, so that the base 104 of the nipple shield 60 and the translucent flow indicator 108 are placed inside the box body 144.

[0118] Figure 26-31 The box body 144 is shown to have a box body protrusion 166 positioned substantially centrally within the box body 144. From the bottom of the box body 144, the box body protrusion 166 extends conically upward to an end 174 of the box body protrusion. (Reference) Figures 27A-27B The box body protrusion 166 is configured to mate with the protrusion 106 of the nipple shield 60. The end 174 of the box body protrusion has a crenellated structure. As used herein and throughout this disclosure, the crenellated structure is similar to the top notch seen on the upper part of a castle wall. The crenellated structure or the top wall of a castle has a wall extending upward around the base, the wall having alternating portions called "crenellations" (i.e., solid portions) and "crenellations" (i.e., openings). Similarly, the end 174 of the protrusion may have a recessed bottom wall 174a located within the end 174 of the protrusion. The slightly recessed bottom wall 174a of the end of the protrusion is surrounded by a crenellated wall formed by solid portions and openings, similar to the top of a castle. The box body protrusion 166 with the end 174 of the protrusion may also be similar to a chimney with an uneven top. The crenellated wall may resemble a scalloped wall or a similar structure, defining a plurality of openings or notches 176, allowing steam to flow directly through the openings or notches 176 into the central portion above the bottom wall 174a of the protrusion end 174, and directly into the opening in the nipple shield 60, which will be discussed in more detail later in this disclosure. It should be understood that the protrusion end 174 may have at least one solid portion and one opening. The advantage of the plurality of notches 176 is that it overcomes any seal that may be formed between the housing protrusion 166 and the protrusion 106 of the nipple shield 60. It should be understood that the housing protrusion end 174 may have alternative constructions, such as, but not limited to, rounded ends, a single notch, or any other suitable construction capable of engaging with the protrusion 106 of the nipple shield 60. Furthermore, it should be understood that the housing protrusion 166 may have alternative embodiments, such as, but not limited to, cylindrical, dome-shaped, rectangular, or any other suitable construction capable of receiving the protrusion 106 of the nipple shield 60.

[0119] Back Figure 27BThe box protrusion 166 may also have at least one channel 178 extending upward from the base of the box protrusion 166 to the end 174 of the box protrusion. The at least one channel 178 may be evenly distributed around the entire periphery of the box protrusion 166. Furthermore, the box protrusion 166 may be removably secured to the box body 144 by any suitable fastening method, such as, but not limited to, press-fit, mating magnet, snap fastener, or any other suitable fastening method capable of removably securing the box protrusion 166 to the box body 144. It should be understood that the box protrusion 166 may also be molded onto the box body 144. The box protrusion 166 may also have at least one internal channel 180 centrally passing through the opening in the box protrusion 166. The at least one internal channel 180 may have at least one channel inlet 182 located at the base of the box protrusion 166, the inlet communicating with the at least one internal channel 180. The at least one internal channel 180 allows the generated steam to flow from at least one channel inlet 182 through at least one internal channel 180 and into the nipple shield 60, which will be discussed in more detail later in this disclosure.

[0120] Figures 27A-27B The housing protrusion 166 is shown to be surrounded by a recess or housing reservoir 168, which extends radially outward and downward toward the housing end 158 from the upper center of the housing 144 and curves inward to surround the housing reservoir 168. The recessed reservoir 168 is configured to contain cleaning fluid 170, such as, but not limited to, water, soap, or any other suitable liquid capable of cleaning, rinsing, and / or disinfecting the nipple shield 60 as described in this disclosure. In a predetermined section of the housing reservoir 168, a housing fill line indicator 192 surrounds the periphery of the housing reservoir 168. The housing fill line indicator 192 serves as a visual indicator for the user to show how much cleaning fluid 170 is required for the use of the disinfection box 140.

[0121] Figure 27A , 27BFigures 31-32 show that the housing 144 has two crescent-shaped protrusions 172 located on the middle surface above the housing reservoir 168. A nipple shield 60 is housed within and aligned with the housing 144, with a protrusion 106 located on top of the housing protrusion 166, and the two crescent-shaped protrusions 172 receiving the upper portion of the translucent flow indicator 108. The advantage of the two crescent-shaped protrusions 172 is that they stabilize the nipple shield 60 when it is housed within the housing 144. For example, when the nipple shield 60 is closed by the cap 142, the crescent-shaped protrusions 172 align and stabilize the nipple shield 60, and reduce lateral movement of the nipple shield 60 when the sterilization housing 140 is moved, preventing damage to the delicate nipple shield 60. The two crescent-shaped protrusions 350 also serve as guides for the user to properly insert the nipple shield 60 into the housing 144. For example, the user can use the two crescent-shaped protrusions 172 to ensure that the nipple shield 60 is properly inserted into the housing 144, because the two crescent-shaped protrusions 172 coincide with the tapered portion of the nipple shield 60, causing the translucent flow indicator 108 to be oriented above the base 104 of the nipple shield 60, such as Figures 31-32 As shown. It should be understood that the two crescent-shaped protrusions 172 may have alternative implementations, such as, but not limited to, cylindrical, rectangular, triangular, circular or any other suitable shape capable of stabilizing the nipple shield 60 or equivalent infant device as described in this disclosure.

[0122] The operation of the disinfection box 140 is as follows: The user lifts the lid 142 to the position as shown in the image. Figure 26 , 27A The user opens the disinfection box 140 using the opening configuration shown in 27B. The user then pours the cleaning solution 170 into the box's reservoir 168 until the box fill line indicator 192 is reached. The user then proceeds as shown in Figure 27B. Figures 31-32 As shown, the nipple shield 60 is placed inside the box, and then the sterilization box 140 is closed by hingedly covering the box body 144 with the lid 142 and ensuring that the box lock 156 is engaged. The user can then place the sterilization box 140 in a heating device, such as, but not limited to, a microwave oven, to heat the cleaning solution 170 to a boiling temperature, causing the cleaning solution 170 to turn into steam.

[0123] Figure 33The generated steam traces upward from the container reservoir 168, passes over the container protrusion 166, and then enters the nipple shield 60 through multiple notches 176. The steam then covers all surfaces of the nipple shield 60 and enters the fluid channel 114 of the nipple shield 60, subsequently passing through the translucent flow indicator 108 and exiting from multiple openings 116, thereby effectively cleaning and sterilizing the nipple shield 60. For example, the steam may expel any residue (e.g., breast milk) left in the fluid channel from the nipple shield 60. The combination of heat and the potential sterilizing power of the cleaning fluid 170 sterilizes the nipple shield 60 for continued safe use. In an alternative embodiment where the sterilization box 140 has at least one channel 178 on the container protrusion 166 or at least one internal channel 180 within the container protrusion 166, the steam may be guided by at least one channel 178, or enter at least one internal channel 180 from the container reservoir 168 upward through at least one channel inlet 182 and into the fluid channel 114. It should be understood that the sterilization box 140 may have any combination of multiple notches, at least one channel 178 and / or at least one internal channel 180 to properly guide steam from the box body reservoir 168 upward into the nipple shield 60 or equivalent mating device.

[0124] The disinfection box 140 may also be placed in a container containing hot water or an equivalent liquid, allowing the cleaning solution 170 to be converted into steam as described in this disclosure. For example, the disinfection box 140 may be placed in a boiling water tank capable of raising the temperature of the cleaning solution 170 to generate steam. Furthermore, it should be understood that, in alternative embodiments, the material properties of the disinfection box 140 may include, but are not limited to, metal, plastic, polymer, or any other suitable material capable of withstanding the temperature required to raise the temperature of the cleaning solution 170 to generate steam, as described in this disclosure.

[0125] The sterilization box 140 can be used to sterilize other baby-related products, such as, but not limited to, pacifiers, bottle nipples, teething toys, or any other baby products that may require cleaning, rinsing, and / or sterilization and can be fitted into the sterilization box 140 as described in this disclosure. Furthermore, the sterilization box 140 can be used to store and securely preserve said related items, such as nipple shields, for travel purposes or to limit exposure to the atmosphere.

[0126] Figures 34-43 Another embodiment of the sterilization box 240 is shown, which may have alternative embodiments capable of achieving the features described in this disclosure. As shown, the sterilization box 240 can take various different shapes and configurations. The sterilization box 240 is more shaped like a soap bar, having an upper curved top cover 242 and a lower curved box body 244 with an internal liquid reservoir 268. Similarly, a box body protrusion 266 is provided to align and secure the nipple shield 60 during storage and cleaning. Figure 40As shown, in other alternative embodiments, the container reservoir may be configured to include a heating plate 200 capable of generating steam from the cleaning fluid 170. The advantage of including a heating plate is that it allows for portability during travel, enabling the safe storage of nipple shields 60 or other products within the sterilization box 240 while simultaneously sterilizing the products.

[0127] Figure 44-49 One embodiment of a sterilization storage box 300 is shown. The sterilization storage box 300 is configured to house and / or sterilize both the flushing syringe 10 and the nipple shield 60. The sterilization storage box 300 has a sterilization storage box lid 304 that projects uniformly, radially outward and downward from the sterilization storage box hinge 306. The sterilization storage box lid 304 then curves inward to the sterilization storage box end 308. The sterilization storage box lid 304 is pear-shaped, having a solid exterior and a hollow interior, and is configured to hingedly enclose the nipple shield 60 and the flushing syringe 10 within the sterilization storage box body 318. It should be understood that the sterilization storage box lid 304 may have alternative shapes, such as, but not limited to, dome-shaped, rectangular, triangular, or any other suitable shape capable of covering the nipple shield 60 and the flushing syringe 10 of the alternative embodiments of this disclosure. From the sterilization storage box end 308, the sterilization storage box lid 304 extends radially downward into a tab 310.

[0128] The tab 310 extends outward from the disinfection storage box lid 304. This outward extension of the tab 310 from the disinfection storage box lid 304 provides a lever for the user to easily grip the tab 310. A disinfection storage box locking aperture 312 is centrally positioned on the tab 310. The disinfection storage box locking aperture 312 is configured to receive a disinfection storage box locking protrusion 314 located on the end 320 of the disinfection storage box body. The disinfection storage box locking aperture 312 and the disinfection storage box locking protrusion 314 together form a disinfection storage box lock 316. When the disinfection storage box lid 304 is hingedly closed onto the disinfection storage box body 318, the tab 310 presses against the disinfection storage box locking protrusion 314, causing the disinfection storage box locking protrusion 314 to be received within the disinfection storage box locking aperture 312, thereby securing the disinfection storage box lid 304 to the disinfection storage box body 318. The user can then use the tab 310 to lift the disinfection storage box lid 304 from the disinfection storage box locking protrusion 314, thereby opening the disinfection storage box 300. It should be understood that the disinfection storage box lock 316 may have alternative implementations, such as, but not limited to, a magnetic lock, a locking notch, a snap fastener, or any other suitable locking mechanism capable of securing the disinfection storage box lid 304 to the disinfection storage box body 318 of this disclosure.

[0129] Figures 50-53The disinfection storage box body 318 is shown extending radially outward and downward uniformly from the disinfection storage box hinge 306, then curving inward to the disinfection storage box body end 320. The peripheral edge of the disinfection storage box body 318 has a recessed edge 322 that extends downward from the disinfection storage box hinge 306 to the disinfection storage box body end 320 around the periphery of the disinfection storage box body 318.

[0130] At least one recess 352 is located near the hinge 306 of the disinfection storage box. At the end 320 of the disinfection storage box body, the recessed edge 322 extends radially downward to form a disinfection storage box tab groove 356 configured to receive the tab 310. The disinfection storage box locking protrusion 314 is thus centrally positioned in the disinfection storage box tab groove 356. The recessed edge 322 is configured to receive a mating lip 324 located on the outer periphery of the disinfection storage box cover 304, which extends from the disinfection storage box hinge 306 around the disinfection storage box cover 304 and into the tab 310.

[0131] Figure 46 and 48 At least one lid recess 354 adjacent to the disinfection storage box hinge 306 is shown. When the disinfection storage box 300 is hingedly closed onto the disinfection storage box body 318, the recessed edge 322 and the mating lip 324 form a seal. Furthermore, at least one body recess 352 and at least one lid recess 354 form a vent 326. The vent 326 allows generated vapors during the use of the disinfection storage box 300 to escape from the disinfection storage box 300 for depressurization. For example, when the disinfection storage box lid 304 is hingedly closed onto the disinfection storage box body 318, the mating lip 324 is positioned within the recessed edge 322, and in conjunction with the disinfection storage box lock 316, the contents of the disinfection storage box 300 are sealed inside. As the temperature of the disinfection storage box 300 increases to generate vapors, the pressure also increases accordingly, thus requiring depressurization, and the vent 326 allows this pressure to be released.

[0132] The sterilization storage box body 318 protrudes downward from the recessed edge 322 to the base 326 of the sterilization storage box body. The upper part of the base 326 of the sterilization storage box body has a protrusion to form an arched support 328 configured to accommodate the nipple shield 60, such that the base 104 of the nipple shield 60 and the translucent flow indicator 108 are placed inside the sterilization storage box body 318.

[0133] The sterilization storage box body 318 has two crescent-shaped protrusions 350 located on the upper center of the sterilization storage box body 318. The two crescent-shaped protrusions 350 are configured to fix and / or stabilize the nipple shield 60, which will be discussed in more detail later in this disclosure. The two crescent-shaped protrusions 350 can also serve as guides for the user to properly insert the nipple shield 60 into the sterilization storage box body 318. For example, the user can use the two crescent-shaped protrusions 350 to ensure that the nipple shield 60 is properly inserted into the sterilization storage box body 318, because the two crescent-shaped protrusions 318 coincide with the tapered portion of the nipple shield 60, causing the translucent flow indicator 108 to be oriented above the base 104 of the nipple shield 60, such as... Figures 54-55 As shown. It should be understood that the two crescent-shaped protrusions 350 may have alternative implementations, such as, but not limited to, cylindrical, rectangular, triangular, circular, or any other suitable shape capable of stabilizing the nipple shield 60 or equivalent infant device as described in this disclosure.

[0134] Furthermore, the sterilization storage box body 318 has a box body protrusion 330 centrally located within the arched support portion 328. The box body protrusion 330 extends conically upward from the base 326 of the sterilization storage box body and then tapers inward to the end 332 of the box body protrusion. The box body protrusion 330 is configured to engage with the protrusion 106 of the nipple shield 60.

[0135] The end 332 of the housing protrusion has a plurality of notches 302 to guide steam into the fluid channel 114 of the nipple shield 60, which will be discussed in more detail later in this disclosure. It should be understood that the end 332 of the housing protrusion may have alternative constructions, such as, but not limited to, triangular ends, elliptical ends, rectangular ends, or any other suitable construction capable of engaging with the protrusion 106 of the nipple shield 60. Furthermore, it should be understood that the housing protrusion 330 may have alternative embodiments, such as, but not limited to, cylindrical, dome-shaped, rectangular, or any other suitable construction capable of receiving the protrusion 106 of the nipple shield 60.

[0136] refer to Figure 51 The box body protrusion 330 may also have at least one channel 336 extending upward from the base 326 of the sterilization storage box body to the end 332 of the box body protrusion. The channel 336 may be evenly distributed around the entire periphery of the box body protrusion 330. The channel 336 may have an opening on the exterior of the box body protrusion 330. Furthermore, the box body protrusion 330 may be removably secured to the sterilization storage box body 318 by any suitable fastening method, such as, but not limited to, press-fit, mating magnet, snap fastener, or any other suitable fastening method capable of removably securing the box body protrusion 330 to the sterilization storage box body 318. It should be understood that the box body protrusion 330 may also be molded onto the sterilization storage box body 318.

[0137] Figure 57 The housing protrusion 330 may also have at least one internal channel 338 centrally passing through the opening in the housing protrusion 330. The internal channel 338 may also have at least one channel inlet 340 located at the base of the housing protrusion 330, communicating with the at least one internal channel 338. The internal channel 338 may allow generated steam to flow from the channel inlet 340 through the internal channel 338 and into the nipple shield 60, which will be discussed in more detail later in this disclosure.

[0138] The housing protrusion 330 is surrounded by a housing reservoir 342, which extends radially outward and downward toward the housing end 320 of the disinfection storage box 318, starting from the upper center and curving inward to form the housing reservoir 342. The housing reservoir 342 is configured to contain cleaning fluid 170, such as, but not limited to, water, soap, or any other suitable liquid capable of cleaning, rinsing, and / or disinfecting the nipple shield 60 as described in this disclosure. At a predetermined height, a housing fill line indicator 312 surrounds the periphery of the housing reservoir 342. The housing fill line indicator 312 in the housing reservoir 342 serves as a visual indicator for the user to show how much cleaning fluid 170 is required for cleaning the disinfection storage box 300.

[0139] Starting from the upper part of the base 326 of the disinfection storage box, the base 326 then descends to a basin 346 positioned approximately centrally relative to the base 326. Specifically, a parabolic protrusion 348, configured to receive the flushing syringe 10, is centrally positioned within the basin 346. This parabolic protrusion 348 extends upward from the base 326 of the disinfection storage box into two equidistant flanges.

[0140] Figures 54-56The diagram illustrates that when the flushing syringe 10 is inserted into the parabolic protrusion 348, the parabolic protrusion 348 secures and / or stabilizes the flushing syringe 10 when the sterilization storage box 300 is in the storage position. For example, when the sterilization storage box 300 is closed and the flushing syringe 10 is secured by the parabolic protrusion 348, the parabolic protrusion 348 restricts lateral movement of the flushing syringe 10 as the sterilization storage box 300 moves. A nipple shield 60 is disposed within the sterilization storage box body 318, wherein a protrusion 106 is located on top of a body protrusion 330, and a crescent-shaped protrusion 350 receives the upper portion of the translucent flow indicator 108 of the nipple shield 60. The advantage of the crescent-shaped protrusion 350 is that it stabilizes the nipple shield 60 when it is disposed within the sterilization storage box body 318. For example, when the nipple shield 60 is closed by the sterilization storage box lid 304, the crescent-shaped protrusion 350 stabilizes the nipple shield 60 and reduces the lateral movement of the nipple shield 60 when the sterilization storage box 300 moves.

[0141] The sterilization storage box 300 allows the user to simultaneously store and sterilize the nipple shield 60 and the rinsing syringe 10. In the storage configuration, the user simply raises the sterilization storage box lid 304 to the open position and inserts the nipple shield 60 above the box body protrusion 330 and between the two crescent-shaped protrusions 350, aligning them. The user then places the rinsing syringe 10 within the parabolic protrusion 348 and closes the sterilization storage box lid 304 onto the sterilization storage box body 318, ensuring the sterilization storage box lock 316 engages. The user can then travel with the sterilization storage box 300, in which the nipple shield 60 and the rinsing syringe 10 are secured.

[0142] Figure 60 An exemplary method is shown for cleaning the nipple shield 60 and rinsing the syringe 10 within sterilization storage boxes 240, 300, and 400. In step S1, the sterilization storage box is opened. Proceed to step S2.

[0143] In step S2, the liquid reservoir in the container is filled with cleaning fluid up to the container fill line indicator. Proceed to step S3.

[0144] In step S3, the nipple shield 60 or an alternative device is placed in the sterilization storage box. The alternative device can be, for example, a pacifier, and / or any other device that can be cleaned within the sterilization storage box. Proceed to step S4.

[0145] In step S4, the nipple shield and the sterile storage box in which the replacement device is placed are closed. Proceed to step S5.

[0146] In step S5, the disinfection storage box is placed in the heating device and heated until it boils, turning the cleaning liquid into steam. The steam can then be transferred to the nipple shield 60 to disinfect the fluid channel.

[0147] Alternatively, if the sterilization storage box includes a nipple shield 60 and a rinsing syringe, then proceed to step S6 after step S1.

[0148] In step S6, the flushing syringe 10 is disassembled into two parts: a plunger 40 and a barrel 16, and then... Figure 58 The cylinder 16 is placed in the parabolic protrusion and the plunger 40 is positioned vertically, such that the cylinder 16 is adjacent to the end base 32, and these two parts are arranged in the sterilization storage box. Proceed to step S7.

[0149] In step S7, the cleaning fluid is overfilled into the container's reservoir until it exceeds the fill line indicator, allowing the cleaning fluid to fill the container's basin until it reaches the base of the parabolic protrusion. Figure 59 As shown. Proceed to steps S4 and S5 respectively.

[0150] like Figure 57 As shown, the generated steam then traces upward from the reservoir, passes through the housing protrusion, then enters the nipple shield 60 through multiple notches and into the fluid channel, before exiting through a translucent flow indicator and multiple openings, thereby cleaning and sterilizing the nipple shield 60 with the generated steam. For example, the steam can expel any residue (e.g., breast milk) left in the fluid channel from the nipple shield 60. The combination of heat and the potential sterilizing power of the cleaning fluid sterilizes the nipple shield for continued safe use. In an alternative embodiment where the sterilization storage box has at least one channel on the housing protrusion or at least one internal channel within the housing protrusion, the steam can be guided upward from the reservoir and into the fluid channel by the at least one channel or the at least one internal channel. It should be understood that the sterilization storage box may have any combination of multiple notches, at least one channel, and / or at least one internal channel to suitably guide steam upward from the housing reservoir into the nipple shield 60 or equivalent connecting device. In addition, the generated steam sterilizes the exterior of the plunger 40 and the cylinder 16, and can also enter the liquid storage chamber 22, thereby effectively sterilizing it.

[0151] The sterilization storage box can also be placed in a container filled with hot water or an equivalent liquid, such that the cleaning solution contained within the sealed sterilization box and its nipple shield can be converted into steam as described in this disclosure. For example, the sterilization storage box can be placed in a boiling water tank capable of raising the temperature of the cleaning solution to generate steam. Furthermore, it should be understood that, in alternative embodiments, the material properties of the sterilization storage box may include, but are not limited to, metal, plastic, synthetic materials, or any other suitable material capable of withstanding the temperature required to raise the temperature of the cleaning solution to generate steam as described in this disclosure.

[0152] It should be understood that the sterilization storage box can be used to sterilize other baby-related products, such as, but not limited to, pacifiers, bottle nipples, teething toys, or any other baby products that may have crevices that require washing, cleaning, and / or sterilization. Furthermore, it should be understood that the sterilization storage box 300 can be used to store and safely preserve said related items, such as nipple shields, for travel purposes or to limit exposure to the atmosphere.

[0153] The material properties of the sterilization storage box 300 may include, but are not limited to, plastics, polymers, or other suitable materials capable of withstanding the heating conditions required to generate steam as described in this disclosure.

[0154] Figures 61-66 Another embodiment of the disinfection storage box 400 is shown, which may have alternative embodiments capable of achieving the features described in this disclosure. As shown, the disinfection storage box 400 may take various different shapes and configurations. The disinfection storage box 400 is more rectangular in shape, having an upper curved lid 442 and a box body reservoir 444 with a substantially flat bottom. An arched support 428 and a parabolic protrusion surround the box body reservoir 444 to align and secure the nipple shield 60 and the rinsing syringe 10, respectively, during storage and cleaning.

[0155] like Figure 66 As shown, the container's liquid reservoir 444 can be configured to include a heating plate 460 capable of generating steam from the cleaning liquid 170. The heating plate 460 may include an internal power source (not shown), such as, but not limited to, a rechargeable battery. The internal power source can be connected to a heating element (not shown) to raise the temperature of the heating plate 460 to generate steam from the cleaning liquid 170. The heating element may be, but is not limited to, a heating coil. The advantage of including the heating plate 460 is that it allows for portability during travel, enabling the safe storage of nipple shields 60 or other products within the sterilization storage box 400 while also sterilizing the products.
