[0002] This application is a divisional application of the Chinese invention patent application with application date of May 20, 2019, application number 201980048518.3, and title “Container assembly for a breast pump”. Technical Field

[0003] The present disclosure generally relates to container assemblies for portable breast pump systems and methods for collecting breast milk from a nursing mother's breast. Background Art

[0004] As more women realize that breastfeeding is the best source of nutrition for their infants and is also beneficial to the health of the nursing mother, the need for a user-friendly, quiet, discrete and versatile breast pump solution for use by nursing mothers in a variety of situations is increasing. This is particularly true for working mothers who are away from home for 8 to 10 hours or more and need to express breast milk in order to provide breast milk for her baby, but it is also a requirement for many other situations where these mothers are away from the privacy of the home for extended periods of time, such as when shopping, dining out or other activities.

[0005] Although there are a variety of breast pumps available, many are clumsy and cumbersome, require many parts and components and are difficult to transport. Manually driven manual breast pumps are cumbersome to use and can be inconvenient to use. Some electric breast pumps require plugging into an AC power source during use. Some systems are battery-powered, but these systems drain the battery power quite quickly as the electric breast pump is continuously operated to maintain suction during the milk extraction process. Some other available suction pumps lack a convenient storage container. The storage container can be difficult to pack, install, remove and store, creating a barrier to effective use.

[0006] Therefore, there remains a need for a conveniently usable and effective container assembly for a portable, wearable breast pump. The present disclosure addresses these and other needs. Summary of the invention

[0082] Figure 1A to Figure 1B 1 are perspective and rear views of a breast pump system 10 according to an embodiment of the present disclosure. The breast pump system 10 may include one or more of the features or functions introduced or described below, or a combination thereof. The housing or shell 12 of the system 10 may be shaped and configured to conform to the user's breast in contour and thereby provide a more natural appearance when under the user's clothing. As can be appreciated from the various figures, the system may define a natural breast contour. It is envisioned that the natural breast contour comfortably and conveniently fits the user's bra and presents a natural appearance. A curved surface having an asymmetrical pattern extends from the base. Further, as with a natural breast, it is envisioned that the contour of the device or system defines one or more asymmetrical curves and an eccentric center of inertia. A variety of natural breast shapes may be provided to be selected according to the user's taste and needs. The opposite side of the pump system 10 is configured with a flange 14 that is sized and shaped to engage the user's breast. The contour of the flange 14 is configured to comfortably fit a wide range of user body shapes and provide a structure for sealingly engaging with breast tissue.

[0083] FIG. 2A to FIG. 2B The various steps of loading the container assembly 120 into the system 10 are shown in FIG. Figure 2A ), the flange 14 is removed from engagement with the rest of the system 10. Attached to the flange is a flexible conduit or tube 32. The central portion of the container assembly 120 is placed over the central protrusion 110 of the flange 14 and the flexible conduit or tube 32. Next, the user can grasp the container assembly and structure it under the flexible conduit or tube 32, and then insert the container 120 into the flange 14. An opening 132 (see, for example, FIGS. 2 and 3 ) leading to the interior of the container assembly 120 is formed. Figure 3 ) such as via the pump outlet 138 fluidly connected to the flexible conduit or tube 32. Once connected, the door assembly 90 can be rotated on the flexible conduit or tube assembly 82 and the pump outlet connection (see Figure 1A ) to provide support and secure joints between the parts.

[0084] It is contemplated that a door assembly 90 (see Figure 1B) to provide a continuous profile of the flange 14 to engage the user's breast and to support the engagement of the container assembly 120 with the system 10. Thus, the door assembly 90 can be configured to pivot relative to the flange 14 and can be used to close the system 10 when the door assembly is snapped onto the pump and the pump is closed. In this way, the container assembly 120 is securely clamped within the door assembly 90.

[0085] As described in conjunction with the embodiments presented below, the system 10 can be configured to pump into a container assembly. In one or more approaches, the container assembly can include various embodiments of a fitting that can be attached to or integrally formed with the bag assembly such that it is associated with or molded with one or more sheets that define a bag structure or other structure that defines an inlet to the interior of the container assembly. Such a fitting is configured to cooperate with a suction structure and, in particular, with a flexible conduit or other conduit through which breast milk is pumped. A sealed and / or airtight structure can retain liquids and gases without permitting leakage.

[0086] In at least one embodiment, the pressure at which a valve (not shown) between the pump system and the container assembly is configured to open to allow flow into the breast milk collection container is about 25 mm Hg. The valve can be configured and designed to allow fluid to flow through the valve when the pressure is positive (e.g., about 25 mm Hg, or some other pre-designed "opening pressure"). The valve can also be included in the container assembly itself.

[0087] Reference now Figure 3 , an embodiment of a sealed or sealable container assembly 120 is shown. In a particular embodiment, the container assembly 120 can be formed by approximately two 2.5 mil to 3.0 mil sheets of material, which are coupled (i.e., welded) along the periphery 122 of the assembly, and the size of the container assembly can be set to hold up to 3.5 ounces or alternatively 8 ounces or more of fluid. The body of the container assembly (e.g., 4oz, 8oz) is shaped to fit within the flange 14 (such as 24mm, 27mm size) and include a generally elliptical opening 124 formed by an internal seal. A narrow neck portion 128 is centrally positioned and extends longitudinally away from the central opening 124. The container assembly 120 can be resealable, reusable, including larger or smaller openings, or including a spout structure for pouring contents. With a rounded shoulder and internal opening, the volume capacity can be about 6 ounces or more.

[0088] In addition, in a specific embodiment, the container assembly 120 can be made of polyethylene, and can be free of bisphenol A, and is a food grade material. The assembly is freezeable without tearing, and can withstand temperatures of about -80 degrees Celsius. Additionally, the tensile strength can be 2300psi to 2900psi, and the tear strength can be 440psi to 600psi, wherein the water vapor permeability is about 0.5g / 100in2 / 24h at most, and the oxygen transfer rate is about 150cc / 100in2 / 24h. In alternative embodiments, for example, the material of the container assembly may include Gore-Tex or Tyvek. This alternative material can allow exhaust, so that any air sucked into the container assembly will escape through the material, while the container assembly keeps the fluid. In terms of this specific aspect, other exhaust ports or methods for exhausting the system are incorporated into one or more embodiments. Therefore, it can be adapted to exhaust the container assembly itself or actively exhaust it when using the pump system or after use.

[0089] like Figure 4 As shown, the container assembly 120 may lack a central oval opening and instead include a central portion defined by a scored material or a material having slits such as defining a cross 130 that is configured to open when the container assembly is placed into a breast pump system. This method lends itself to ease of manufacture as no central opening needs to be formed and no material needs to be removed therefrom. In the embodiments presented in the various figures, the opening 132 to the interior of the assembly is located in the neck portion.

[0090] like FIG. 5A to FIG. 5C As shown, the container assembly also includes an area 140 designated as defining a writable space. Various information, such as information related to the suction zone, can be written in such an area, and such an area can be provided anywhere on the container assembly. It is noteworthy that the user can see this and other printing on the container assembly through the transparent or otherwise conveniently constructed flange, which is equally useful in the case where an alignment indicator is provided on the container assembly. For example, a colored ring around the opening of the container assembly can highlight the area around the flange channel and from which the breast needs to enter the flange.

[0091] refer to FIG. 6A to FIG. 6G In various embodiments, the container assembly 120 also includes an additional spout 150 for pouring collected breast milk. Such a spout 150 can be placed at various locations around the body of the container assembly. The outlet of the spout can be formed by cutting the spout material, or the spout can additionally include a score or a resealable opening.

[0092] Additionally or alternatively, the container assembly 120 also includes one or more vents 160, such as a Porex vent or its equivalent (see Figure 7). When breast milk is pumped into the container assembly 120, the vent 160 releases air, in which case there is a one-way valve placed to be attached to or integrated with the breast pump system or container. In one embodiment, once the vent 160 is exposed to moisture or otherwise blocked, it no longer allows air or fluid to pass through. However, if the vent becomes dry again, it will still allow a certain degree of air flow. Therefore, if the vent 160 is exposed to moisture, the vent 160 is sealed to avoid fluid leakage. This particular container assembly 120 is also characterized by an internal seal 162, which facilitates the operation and operation of the vent 160 by transferring the collected breast milk and air within the container assembly in a desired manner, for example, such as the function of retaining a hole sticker that needs to be kept dry to exhaust air. Therefore, in one embodiment, the internal seal 162 transfers fluid from the vent, so the vent remains operational and continues to allow air to be exhausted from the container assembly. Thus, the user can pump more fluid into the container assembly 120 without compromising the container volume with air, and the container assembly 120 defines a lower profile when stored. Furthermore, this approach results in a reduction in the number of container assemblies used in a single pumping session, especially for new breast pump system users who may pump more air into the system due to multiple realignments with the breast.

[0093] In another method ( Fig. 8A ), the container assembly 120 includes an additional sealing point or tack weld in the shoulder of the container assembly 120. Such tack weld 170 increases adhesion between the container film layers to prevent fluid backflow and breast milk spillage during removal and disposal of the container 120 after the pumping session is completed. In addition, due to the positive pressure of the pump system, such tack welds or other adhesion between the layers do not adversely impede fluid flow in the container, but limit outward flow and therefore spillage.

[0094] Go to Figure 8B , shows a container assembly 120 that includes a pair of internal seals 162 that are configured to transfer collected breast milk from the inlet to the container assembly. This embodiment also includes a sealing portion 172 that is arranged not to receive breast milk but is otherwise provided as an area for a user to write on. This embodiment also includes a spout 150 that is configured into the lower portion of the container assembly 120.

[0095] like Figures 9 to 11 As shown, additional or alternative portions of the container assembly may be sealed or tack welded together. In one method ( Fig. 9), the container membrane is sealed to the rear portion of the fitting 180. Here, a generally keyhole-shaped path 182 is formed around the fitting to define a fluid path from the flexible conduit through the fitting 180 and into the body of the container assembly 120. Alternative sealing patterns 190, 200 ( Figure 10 to Figure 11 ) to form a desired path out of the fitment 180 and into the body of the container assembly 120. This sealing pattern is adjusted or configured to achieve the desired membrane tension and breast pump cleaning efficiency.

[0096] In another embodiment, FIG. 12A to FIG. 12C As shown, the container assembly 120 includes a double membrane valve 210. The double membrane valve 210 is formed by an additional membrane layer sealed in the interior of the container. Various patterns of sealing layers can be used. In a specific embodiment, the layer defines a wishbone-like geometry to accommodate the container assembly geometry. The membrane valve 210 is sealed to the back of the fitting 180, and the fluid flows through the wishbone structure and into the body of the container assembly 120. When the fluid is purged through the fitting and exits the double membrane valve or in the case where the fluid is pushed into the container assembly, the layers separate and allow the fluid to pass through the container assembly ( Fig. 12C ). In its resting state or under passive pressure ( Fig. 12B ), the membrane layers come together and act as a valve (the membrane layers maintain a seal under tension). The geometry of the bilayer can be modified to adjust the performance of the bilayer valve, such as to achieve a desired flow restriction or efficiency as a valve.

[0097] Now turn to FIG. 13A to FIG. 13E , another method of fitting 230 for container assembly 120 is shown. The fitting 230 includes an inverted fitting boss 232 that protrudes from a base 233 and is configured to increase or provide sufficient film tension between the boss 232 and the inner bag surface and prevent fluid from flowing back out of the container ( Fig.13E ). Protruding from the opposite side of the base 233 is a cylindrical boss 234 that defines a passage into the container assembly 120. When so configured, the inverted boss 232 acts to reduce fluid backflow and spillage of collected breast milk. Thus, while minimizing the possibility of spilling breast milk, the user is provided with greater flexibility in removing and disposing of the container assembly 120 after completing the suction session.

[0098] Now turn to FIG. 14A to FIG. 14D , a double boss fitting 240 is shown. A first boss 242 extends vertically from a generally oval base 243 and includes a through hole defining a passage into the container assembly 120. A second boss 244 is spaced apart from the first boss and protrudes from an opposite side of the base 243. In this embodiment, the base 243 can be folded via a hinge or equivalent structure so that the second boss 244 is aligned with the first boss 242. Fig. 14CAs shown, the base is first folded so that the bosses are aligned when the dual boss fitting 240 is constructed in the container assembly 120. Alternatively, as shown in FIG. Fig.14D As shown, the double boss fitting is constructed in the container assembly in an expanded configuration and then folded so that the second boss 244 is engaged within the first boss 242 using the container film to form an interference fit. Thus, the two bosses are clamped together to close the opening of the container assembly 120, wherein the second boss 244 operates as a cover. In this closed configuration, the container assembly 120 is sealed and sterility is maintained until the container is assembled as part of the breast milk path.

[0099] FIG. 15A to FIG. 15D An alternative method of foldable accessories is shown in FIG. Fig.15A The accessory 250 depicted in FIG. 1 is characterized by a cord structure 252 between a base 253 of a first boss 254 and a second plug boss 255 . Fig. 15B and Fig. 15C The fittings 260, 270 shown in FIG. 2 include a second boss 264, 274 including a through hole and a generally oval base 265, 275. In these methods, the cover seal is formed on the fitting via pressing or interference. Fig.15D The assembly method 280 depicted in FIG. 2 includes a base 282 that is folded along lines that divide through-holes formed in the base 282 .

[0100] FIG. 15E to FIG. 15K Other additional or alternative features of the accessories are shown in FIG. Fig.15E As depicted, the cover or plug may alternatively or additionally include an annular rib 283 configured to pop out through the second generally flat fitting to provide a sealing structure. Here, the cover will be configured on the outside of the bag film. Fig.15F Depicted is a fitting including a sharp sealing internal barb 284 feature that may be included in the fitting as an additional or alternative structure. When the barbs 284 are pressed onto mating structures (each of which may be formed of LDPE), they serve to seal against the outer surface of the fitting. Additionally, as Figure 15G As shown, the accessory may lack a tail and define a general teardrop shape 285, which is used to allow breast milk to flow while taking up less space. Quick tactile feedback between parts can also be incorporated into various accessories ( Fig.15H ). That is, the annular internal barb 286 is configured to seal against a mating structure. In one aspect, a generally hourglass shape is provided that allows and facilitates this functionality. Fig.15IA related approach is shown in , where the accessory may alternatively or additionally include a cap having an annular rib 287 that, when inserted into the accessory boss, pops through an annular undercut in the accessory boss to form a seal and also provide both tactile and audible quick feedback. Additionally, the accessory assembly may also include a narrowed waist 288 connecting the cap and accessory portions, which facilitates folding of the portions (see Fig.15J ), or alternatively, the pieces may be separated and oriented as Figure 15K The arrangement of the fitting and plug assembly 289 is shown in FIG.

[0101] Now turn to Figure 15L to Figure 15P , showing an additional assembly utilizing material interfaces as sealing structures to provide low profile fittings, independent compression between parts, and assembly assistance. In one method ( Figures 15L to 15M ), the short flat fitting boss 290 is configured to engage and seal against a one-way valve assembly 291, which includes a second shot section formed of a TPE material. Thus, the container assembly can take on a low profile structure and be configured to seal with a valve assembly that is separate and distinct from the container assembly. This low profile approach allows the container assembly to occupy less space during both shipping and storage. Tab 293 is provided on the one-way valve assembly 291 and may be round ( Figure 15L ) or rectangular ( Figure 15M ) pattern arrangement. Alternatively or additionally, the flat fitting 290 seals against one or more O-rings 294 ( Fig.15N Here, the valve assembly structure provides compression to the flat fitting to push it against the O-ring 294 and form a face seal. Also, alternatively or additionally, the inner diameter 295 of the flat fitting is arranged to seal against the second shot TPE surface to form a valve assembly boss 296 ( Fig.15O ) outer diameter. Thus, compression for sealing is provided by radial interference. In another aspect, the valve assembly boss can have a TPE outer diameter and can be angled or have a flat top, and the flat fitting can also include an inverted boss to assist breast milk flow into the container assembly.

[0102] In further aspects, one or more components of the fitting may be formed from layers of TPE / LDPE / TPE or similar variations such that the TPE portion serves as a sealing material with a mating portion. Thus, in various aspects, this allows for an all-polypropylene valve assembly. Further, the fitting boss of the valve assembly may be formed from a TPE that sealingly engages with the LDPE fitting such that a radial seal from hard to soft material is provided. The fitting is alternatively or additionally stamped / die-cut from a TPE material wherein the geometric substructure provides flexure where necessary and provides more rigid sections to support stiffness, as stiffness is necessary for sealing, but flexibility is also desired to reduce user assembly forces. The valve assembly may alternatively or additionally include an overmolded TPE surface that interfaces with and seals against a container fitting. Further, the flat fitting may include a face that seals with a TPE face of the valve assembly, the combination forming a seal when the system door cover is placed over the parts. A TPE cylindrical portion 297 may also be placed between the mating portions (see Fig.15N ), where initially there is an annular space around the TPE portion 297 until the fitting is placed within the TPE portion, thereby forming the necessary seal and closing the space. Also, in another aspect, a Santoprene valve assembly portion is provided that naturally rests so that there is a gap around it, and when the second portion is inserted, the Santoprene portion is pushed outward to close the gap and form a seal.

This structural arrangement helps the user to correctly assemble the funnel 494 to the body 492. In another method ( Fig.29), the body 492 may be formed of two pieces that fit along a scalloped edge, i.e., a bottom 502 and a top 504. Here, the top 504 may be removable and sealed to the bottom 502.

[0111] like FIG. 30A to FIG. 30B As shown, the container assembly 510 may be defined by a flange 512 that is configured to mate with a cover or lid 514 that includes an elastomeric region for a bistable port region 516. There is a sealing structure along the perimeter of the joint between the flange 512 and the lid 514. The lid may also additionally include a strike plate or Hall effect actuator component 518 that facilitates communicating that the container assembly is connected to the rest of the breast pump system. Fig. 30A As best shown, the elastomeric region 516 can be placed in its expanded configuration to present a pouring structure that can be capped 519 to store breast milk received within the container assembly 510. The elastomeric region 516 also includes structure for engaging a conduit through which breast milk is pumped into the container assembly 510.

[0112] In the related method ( Fig.31 ), the container assembly 520 is embodied as a two-part assembly.

Fig.33F The two-part container method 570 depicted in the method is characterized by including a pair of foldable arms 572 extending from the periphery of the cover 574 component; however, either container assembly part may include such structure.

[0117] In addition, the rotating cover 580 ( Fig.34 ) can be attached to the outer surface of any of the disclosed container assemblies. When in the closed configuration, the cover 580 is flush with the outer surface of the container assembly 582 and seals the entrance into the assembly. The container assembly 590 may further or alternatively include a locking ring 592 ( FIG. 35A to FIG. 35B ), which slides over and rotates around the outer surface of the nipple receiving portion 594. The locking ring 592 ( Fig.35A) half a turn, for example, can pull the mating pieces of the container assembly 590 together for assembly purposes. In a related approach, the locking ring 592 includes a tab 593 that locks on a projection 595 extending from the container assembly to complete the locking of the flange to the container assembly.

[0118] like FIG. 36A to FIG. 36I As shown, the container assembly may be embodied in a reusable bag container assembly 600 that is sized and shaped to fit within a breast pump system and cooperate with a conduit that contains pumped breast milk. Fig.36A As shown, the reusable bag container assembly 600 can be configured to occupy the entire available space within a breast pump system. FIG. 36B to FIG. 36D As shown, the container assembly 600 may additionally or alternatively include an open or partially open lower end 602 that is equipped with a button, snap, magnet and / or Velcro 604 for sealing the assembly in a closed configuration. When placed inside the breast pump system, the lower portion 602 of the container assembly folds over itself and is closed using a sealing device. In a related method ( FIG. 36E to FIG. 36F ), the upper portion 610 of the container assembly 600 is folded to seal the container 600. As shown, the upper portion 610 includes a hole 612, the size and shape of which is set to fit on a fitting 614 configured in the container. FIG. 36G to FIG. 36H As shown, the container assembly 600 may include a removable cover 618 that provides access to the interior of the assembly and a convenient port for pouring collected breast milk. Fig.36I Depicted is a bag container assembly 630 that forms a cylinder wrapped around a structure inside a breast pump system. At one end of the assembly is configured a replaceable clamp 632 that seals the structure into a closed configuration.

[0119] Fig.36J A reusable bag container assembly 640 is depicted that includes a superior rim with a zip lock seal 642. This structure conveniently seals the assembly 640 for use in a breast pump system and for storage when needed. The contents of the assembly 640 can be removed by separating the zip lock seal. In addition, as FIG. 37A to FIG. 37C As shown, a one-way valve pouring plug device 650 can be incorporated into one or more of the container assemblies described herein. The device includes a strip 652 connecting a one-way valve portion 654 to a pouring spout plug portion 656. A tab 658 for gripping is also provided at the terminal end of the device. FIG. 37A to FIG. 37B As best shown, the device 650 can be attached to a flange or other container component and function as both a controlled access port and a port for pouring collected breast milk.

[0120] refer to FIG. 38A to FIG. 38G , various alternatives for pouring spout 660 of a container assembly are shown. The container assembly may have a lid to seal the pouring spout during suction, transportation and storage. The lid may be of various shapes, sizes, and is configured to cooperate with the spout at various positions in the container assembly. Therefore, the pouring spout 660 may present different geometric shapes, and each pouring spout may adapt to a brush or other cleaning device to easily clean the interior of the container assembly. The lip 662 formed around the spout 660 facilitates controlled breast milk transfer and minimizes overflow. In addition, certain spout geometries allow pouring from multiple orientations with and without a pump assembly attached. Therefore, for example, the pouring spout may be biased to one side of the container or centered on the top of the container.

[0121] Various other methods of cap 670 are also included to seal a spout formed in a container assembly and / or various integral spouts formed or attached to a container assembly (see FIG. 39A to FIG. 39G ). The lid can be separate, tethered, folded, snapped, or overmolded to the container assembly. In addition, in addition to sealing the pouring spout, the lid can also assist in providing a lip or spout to facilitate transfer of breast milk from the container. That is, the lid 670 may include a tether 672 ( Fig.39A ), the nozzle embodied by the upwardly-turned straw 674 ( Fig.39B )、Internal nozzle 676( Fig.39C ), cover with lip 678 ( Fig.39D )、Folding nozzle 680( FIG. 39E to FIG. 39F ), Spout 682 with cover ( Figure 39G ) or pull-out spout 684 ( Fig.39H )

[0122] FIG. 40A to FIG. 40K A vent or other method of venting a container assembly is shown in FIG. Fig.40A ), a through hole 690 is provided in the container assembly to allow air to be released as the fluid fills the container. Such a through hole may be the same opening as the pouring spout, or may define a separate feature. Alternatively, the through hole may be incorporated into the cover for the spout. There may also be a structure for opening and closing the opening to allow the release of accumulated air pressure. Thus, the closing structure may be a sliding door feature 692 ( Fig.40B ), pivoting or rotating door 694 ( FIG. 40C to FIG. 40D ), rotating or twisting cam feature 696 ( Fig.40E ) or screw cap 698 ( Fig.40F ) embodiment. Alternatively or additionally, the exhaust port structure may include a valve 702 ( Figure 40G), such as an umbrella valve, duckbill valve or diaphragm arrangement, the valve is integrated into the container, such as in the pouring spout or elsewhere, to allow air pressure to be released as the container fills with liquid. This approach also serves to minimize the possibility of liquid spilling as the user moves around. A cap may additionally be provided to seal the valve closed and define a plug or any of the structures described.

[0123] In addition, if Figure 40H As shown, two valves 702 are integrated into the container, wherein a valve at the top of the container will present a lower bursting pressure, thereby allowing air to be released therefrom during the suction section. Here, the user will cover the top valve when completing the suction section, and then perform a flip to complete the operation. The valve at the bottom will have a higher bursting pressure, thereby allowing air to be released during the flip, to complete when the container is inverted. It should be recognized that a porous PTFE membrane can be used to replace the valve to realize the exhaust function, and the membrane allows air to flow but prevents fluid flow. Moreover, the membrane can be hydrophobic and / or oleophobic, and the membrane will be placed near the top and bottom of the container to allow air to be released during standard suction and during the flip completion period. In addition, the hydrophilic PTFE membrane can also be disposable, wherein the user applies the PTFE membrane rod to the pouring spout at the beginning of suction. When suction is completed, the fluid will contact the PTFE membrane and seal the membrane to close it, thereby serving as a lid, until the user is ready to transfer breast milk to a separate container.

[0124] In one aspect, a single valve may be provided near the top of the container that remains naturally open and vents air, but closes in response to increased pressure as the fluid level increases. In a single vent approach, the container may additionally include an internal diaphragm that expands as pressure builds due to the addition of additional air and breast milk during the final steps in the pumping process (such as due to completion of inversion), thereby eliminating the need for a second valve. Fig.40I As shown, the container assembly may additionally or alternatively include one or more elastic balls 704, which are configured to be placed in the channel 706 to open to the outside. When the fluid enters the container, the air is released through the channel. After the inversion is completed, the weight of the fluid pushes the ball 704 to seal the opening to the channel 706.

[0125] like Fig.40J As shown, the valve can be designed into the cap 710, where the cap includes an elastomeric layer that includes a diaphragm valve or duckbill valve 712. After suctioning, the user closes the cap 710 to seal it over the valve 712. Figure 40KAs shown, the container may additionally or alternatively include an internal channel 720 for evacuating air when the container is filled with fluid. Air enters the channel 720 from the top and exits from the bottom of the container. When the user performs a flip to complete, the container is inverted, allowing the channel 720 to fill with fluid.

[0126] Thus, various methods and features for container assemblies and accessories for breast pump systems have been proposed. Each of the disclosed features and structures can be incorporated into a particular method of container assembly or breast pump system to define a convenient and effective structure.

[0127] Although the present disclosure has been described with reference to specific embodiments of the present disclosure, it will be appreciated by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the true spirit and scope of the present disclosure. In addition, many modifications may be made to adapt specific circumstances, materials, compositions of matter, processes, process steps or steps to the purpose, spirit and scope of the present disclosure. All such modifications are intended to fall within the scope of the present disclosure.
