Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates generally to a container assembly for a portable breast pump system and a method for collecting breast milk from a mother's breast during lactation. [Background technology]

[0002] As more women consider breast milk to be the optimal source of nutrition for infants and to provide health benefits to nursing mothers, there is an increasing need for a user-friendly, quiet, discrete, and versatile breast pump solution for use by nursing mothers in a variety of situations. This is especially true for working women who may be away from home for 8 to 10 hours or more and need to express breast milk for their infants, but it is also a requirement for many other situations where mothers are away from the privacy of their home for extended periods of time, such as while shopping, eating out, or engaging in other activities.

[0003] A wide variety of breast pumps are available, but many are cumbersome, cumbersome, require many parts and assemblies, and are difficult to transport. A variety of manually operated hand pumps can be cumbersome and inconvenient to use. Some powered breast pumps require an AC power source that is plugged in during use. Some systems are battery powered, but electric pumps run continuously to maintain suction during the milk extraction process, which drains batteries fairly quickly. Some other available breast pumps do not have a convenient storage container, which can be difficult to pack, install, remove, and store, creating a barrier to effective use.

[0004] Thus, there is a continuing need for a wearable, portable breast pump container assembly that is convenient to use and effective. The present disclosure addresses these and other needs. Summary of the Invention

[0005] Briefly and in general terms, the present disclosure is directed to a container assembly for a breast pump system. The system includes a breast contacting structure and a storage container, and a structure for transferring breast milk or other liquid from the breast to a collection assembly. The method involves pumping breast milk from the breast and transferring the pumped breast milk to the container assembly.

[0018] 1A-B 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 or combinations thereof introduced or described below. The housing or outer shell 12 of the system 10 may be shaped and configured to conform to the shape of the user's breast, thereby providing a more natural appearance under the user's clothing. As is apparent from the drawings, the system may define a natural breast profile. A natural breast profile is considered to fit comfortably and conveniently within a user's bra and to present a natural appearance. A curved surface having an asymmetrical pattern extends from a base. Moreover, like a natural breast, the profile of the device or system may define one or more asymmetrical curves and an off-center center of gravity. A variety of natural breast shape options may be provided to suit the user's preferences and needs. On the opposite side of the pump system 10, a flange 14 is configured to be sized and shaped to engage with the user's breast. The flange 14 is shaped to provide a comfortable fit for a wide range of users' bodies and structure to closely engage breast tissue.

[0019] The various steps of loading the container assembly 120 onto the system 10 are shown in Figures 2A-B. In a first step (Figure 2A), the flange 14 is removed from engagement with the rest of the system 10. Attached to the flange is the flexible conduit or tube 32. The center of the container assembly 120 is placed over the central projection 110 of the flange 14 and the flexible conduit or tube 32. The user may then pick up the container assembly and place it under the flexible conduit or tube 32, followed by tucking the container 120 into the flange 14. An opening 132 to the interior of the container assembly 120 (see Figures 2 and 3 for example) is in fluid communication with the flexible conduit or tube 32, such as via the pump outlet 138. Once connected, the door assembly 90 may be rotated over the flexible conduit or tube assembly 82 and the pump outlet connection (see Figure 1A), providing support and a robust engagement between the parts.

[0020] It is contemplated that a door assembly 90 (see FIG. 1B) may be employed both to provide a continuous contour of the flange 14 for engagement with the user's chest and to support engagement of the container assembly 120 with the system 10. Thus, the door assembly 90 may be adapted to pivot relative to the flange 14 such that it snaps into place to close the pump and thereby close the system 10. In this manner, the container assembly 120 is securely sandwiched within the door assembly 90.

[0021] As described in connection with the embodiments shown below, the system 10 may be configured to pump into a container assembly. In one or more approaches, the container assembly may include various embodiments of fittings that may be attached to or formed integrally with the bag assembly, the fittings being associated with or molded along with one or more sheets that define the bag structure or other structure that defines an access to the interior of the container assembly. Such fittings are configured to mate with the pump structure and in particular with a flexible conduit or other conduit through which breast milk is pumped. The seal and / or airtight structure can retain liquids and gases without allowing leakage.

[0022] In at least one embodiment, a valve (not shown) configured between the pumping system and the container assembly opens to allow flow to the breast milk collection container at a pressure of approximately 25 mmHg. The valve may be configured and designed to allow fluid flow when the pressure is a positive pressure, such as approximately 25 mmHg, or another predetermined "opening pressure." The valve may also be included in the container assembly itself.

[0023] 3, one embodiment of a sealed or sealable container assembly 120 is shown. In one particular embodiment, the container assembly 120 may be formed from approximately 2.5-3.0 mil flat stock joined (i.e., welded) along the perimeter 122 of the assembly and may be sized to hold up to 3.5 ounces, or alternatively 8 ounces or more of fluid. The body of the container assembly (e.g., 4 oz., 8 oz.) is shaped to fit within the flange 14 (24 mm, 27 mm size, etc.) and includes a generally oval opening 124 created by an internal seal. A narrow neck 128 is centrally located and extends longitudinally away from the central opening 124. The container assembly 120 may be resealable, may be reusable, may include a larger or smaller opening, or may include a spout structure for pouring the contents. With a rounded shoulder and inner opening, the volumetric capacity may be approximately 6 ounces or more.

[0024] Further, in certain embodiments, the container assembly 120 is made from polyethylene, which may be Bisphenol A free and may be a food grade material. It may be freezable without tearing and may withstand temperatures of approximately -80 degrees Celsius. Additionally, it may have a tensile strength of 2300-2900 psi, a tear strength of 440-600 psi, a maximum water vapor transmission rate of approximately 0.5 grams / 100 square inches / 24 hours, and an oxygen transmission rate of approximately 150 cc / 100 square inches / 24 hours. In alternative embodiments, the container assembly material may include, for example, Goretex or Tyvek. Such alternative materials may allow for outgassing such that air pumped into the container assembly escapes through the material while the container assembly is holding fluid. In this particular respect, other vents or techniques for ventilating the system may be incorporated into one or more embodiments. Thus, self-ventilation or active ventilation of the container assembly may be achieved during or after use of the milking system.

[0025] As shown in Figure 4, the container assembly 120 may lack a central oval opening and instead include a central portion defined by scored or slitted material to define a cross 130 configured to open when the container assembly is placed in a breast milk pumping system. This approach tends to be easier to manufacture since no central opening needs to be created and no material needs to be removed therefrom. In the embodiment shown in the various figures, the opening 132 to the interior of the assembly is located in the neck.

[0026] As shown in Figures 5A-C, the container assembly also includes areas 140 designated to define a writable space. Various information, such as that related to a pumping session, can be written in such areas, and such areas can be provided anywhere on the container assembly. Notably, such printing and other printing on the container assembly can be viewed by a user through a transparent or otherwise conveniently configured flange, which is also useful when alignment indicators are provided on the container assembly. For example, a colored ring around the opening to the container assembly can highlight the area around the flange tunnel where the breast needs to enter the flange.

[0027] 6A-G, in various embodiments, the container assembly 120 further includes an additional spout 150 for pouring the collected breast milk. Such a spout 150 may be located in various locations near the container assembly body. An outlet for the spout may be created by cutting the spout material, or the spout may additionally include a score line or a resealable opening.

[0028] Additionally or alternatively, the container assembly 120 further includes one or more vents 160, such as a Porex Vent or equivalent (see FIG. 7). The vents 160 release air while milk is being pumped into the container assembly 120, which has a one-way valve attached or integrally disposed to the breast milk pumping system or container. In one embodiment, once the vent 160 is exposed to moisture or otherwise clogged, the vent no longer allows air or fluid to pass through. However, if the vent 160 dries out again, the vent can still allow some air flow. Thus, if the vent 160 is exposed to moisture, it is sealed to avoid leakage of fluid. This particular container assembly 120 is characterized by an internal seal 162 that facilitates operation and function of the vent 160 by redirecting milk and air collected within the container assembly in a desired manner, such as to maintain the function of a Porex patch, which must remain dry to vent air. Thus, in one embodiment, the internal seal 162 diverts fluid away from the vent so that the vent remains functional and maintains the ability to allow air to pass out of the container assembly. As a result, the user can pump more fluid into the container assembly 120 without the container volume becoming compromised with air, and the container assembly 120 defines a lower profile when stored. Additionally, this approach may reduce the number of container assemblies used per pumping session, especially for new users of breast pump systems who may end up pumping more air into the system due to multiple repositioning with the breast.

[0029] In another approach (FIG. 8A), the container assembly 120 includes an additional seal point or tack weld at the shoulder of the container assembly 120. Such a tack weld 170 increases the adhesion between the container film layers to prevent backflow of fluids and spillage of breast milk during removal and handling of the container 120 after a pumping session is completed. Furthermore, such a tack weld or other bond between the layers does not adversely impede the flow of fluids within the container due to the positive pressure of the pump system, but does limit outward flow and therefore spillage.

[0030] 8B, a container assembly 120 is shown that includes a pair of interior seals 162 configured to divert collected breast milk from entering the container assembly. This embodiment further includes a seal portion 172 that is positioned to not receive breast milk but is provided as an area on which a user may write. This embodiment further includes a spout 150 configured within a lower portion of the container assembly 120.

[0031] As shown in Figures 9-11, additional or alternative portions of the container assembly can be sealed or tack welded together. In one approach (Figure 9), the container film is sealed to the rear portion of the fitting 180, where a generally keyhole shaped passage 182 about the fitting is created near the fitting to define a fluid path from the soft conduit through the fitting 180 and into the body of the container assembly 120. Alternating seal patterns 190, 200 (Figures 10-11) may also be employed instead or in addition to create a desired path from the fitting 180 to the body of the container assembly 120. Such seal patterns are tailored or configured to achieve a desired film tension and breast pump purge efficiency.

[0032] In another embodiment, as shown in Figures 12A-C, the container assembly 120 includes a dual film valve 210. The dual film valve 210 is formed from an additional film layer sealed to the interior of the container. Various patterns of sealed layers can be employed. In one particular embodiment, the layers define a wishbone-shaped shape to accommodate the shape of the container assembly. The film valve 210 is sealed to the back side of the fitting 180, and fluid flows through the wishbone structure and exits into the body of the container assembly 120. Where fluid is purged through the fitting and exits the dual film valve, or where fluid is forced into the container assembly, the layers separate, allowing the passage of fluid within the container assembly (Figure 12C). At rest or under passive pressure (Figure 12B), the film layers come together and function as a valve (the film layers remain sealed under tension). The shape of the dual layer can be altered to tune the performance of the dual layer valve, such as for desired flow restriction or efficiency as a valve.

[0033] 13A-E, an alternative approach to a fitting 230 for a container assembly 120 is shown. The fitting 230 includes an inverted fitting boss 232 protruding from a base 233 and configured to increase or provide sufficient film tension between the boss 232 and the interior bag surface to prevent backflow of fluid from the container (FIG. 13E). Protruding from the opposite side of the base 233 is a cylindrical boss 234 that defines a passageway into the container assembly 120. So configured, the inverted boss 232 functions to reduce backflow of fluid and spillage of collected breast milk. Thus, the user is provided with greater flexibility with regard to removal and handling of the container assembly 120 after completing a pumping session while minimizing the possibility of spillage of breast milk.

[0034] 14A-D, a dual boss attachment 240 is shown. A first boss 242 extends perpendicularly from a generally oval base 243 and includes a through hole that defines a passageway into the container assembly 120. A second boss 244 projects from the opposite side of the base 243, spaced from the first boss. In this embodiment, the base 243 can be folded via a hinge or equivalent structure such that the second boss 244 aligns with the first boss 242. As shown in FIG. 14C, when the dual boss attachment 240 is configured into the container assembly 120, the base is first folded so that the bosses are so aligned. Alternatively, as shown in FIG. 14D, the dual boss attachment is configured into the container assembly in an unfolded configuration and then folded to form an interference fit using the container film such that the second boss 244 engages within the first boss 242. In this manner, pinching the two bosses together functions to close the opening to the container assembly 120 with the second boss 244 acting as a cap. In such a closed configuration, the container assembly 120 is sealed and sterility is maintained until the container is assembled as part of a breast milk passageway.

[0035] Alternative approaches to foldable fittings are shown in Figures 15A-D. Fitting 250 depicted in Figure 15A features a leash structure 252 between a base 253 of a first boss 254 and a second plug boss 255. Fittings 260, 270 depicted in Figures 15B and C include a second boss 264, 274 containing a through hole and a generally elliptical base 265, 275. In these approaches, a cap seal is formed against the fitting via compression or interference. Fitting approach 280 depicted in Figure 15D includes a base 282 that folds along a line dividing a through hole formed in the base 282.

[0036] Further additional or alternative features of the fitting are shown in Figures 15E-K. As depicted in Figure 15E, the cap or plug may alternatively or additionally include an annular rib 283 configured to protrude through a second, generally flat fitting to provide a sealing structure. Here, the cap is configured on the outside of the bag film. Figure 15F shows a fitting including a sharp seal internal barb 284 structure that can be included as an additional or alternative structure on the fitting. When the barb 284 is pressed against the mating structure (each of which may be formed from LDPE), it functions to seal against the outer surface of the fitting. Additionally, as shown in Figure 15G, the fitting may lack a tail and define a generally teardrop shape 285, which also functions to allow for the flow of breast milk while taking up less space. Snap tactile feedback between parts can also be incorporated into various fittings (Figure 15H). That is, an annular internal barb 286 is configured to seal against the mating structure. In one embodiment, a generally hourglass shape is provided that enables and facilitates this functionality. A related approach is shown in FIG. 15I, where the fitting may alternatively or additionally include a cap having an annular rib 287 that, when inserted into the fitting boss, projects beyond the annular undercut of the fitting boss to not only form a seal but also provide tactile and audible feedback of the snap. Additionally, the fitting assembly may include a narrowed waist 288 connecting the cap and fitting portions, which may facilitate folding of the parts (see FIG. 15J), or alternatively, the parts may be separated and oriented such as the fitting arrangement shown in FIG. 15K.

[0037] 15L-P, additional assemblies are shown that utilize a low profile fitting, self-contained compression between parts, and a material interface as a sealing structure to provide assembly assistance. In one approach (FIGS. 15L-M), a short flat fitting boss 290 is configured to engage and seal with a one-way valve assembly 291 that includes a second shot section formed from a TPE material. In this manner, the container assembly can assume a low profile structure and be configured to seal with a different valve assembly that is separate from the container assembly. Such a low profile approach allows the container assembly to occupy less space both during shipping and storage. Tabs 293 are provided on the one-way valve assembly 291 and can be arranged in a circular (FIG. 15L) or rectangular (FIG. 15M) pattern. Alternatively or additionally, the flat fitting 290 is sealed against one or more O-rings 294 (FIG. 15N). Here, the valve assembly structure applies compression to the flat fitting, forcing it against the O-ring 294 and forming a face seal. Further, alternatively or additionally, the inner diameter 295 of the flat fitting is positioned to seal against a second shot TPE surface forming the outer diameter of the valve assembly boss 296 (FIG. 15O). Thus, compression for sealing is provided by radial interference. In another embodiment, the valve assembly boss can have a TPE outer diameter and can have an angle or flat top, and the flat fitting can further include an inverted boss to aid in the flow of breast milk into the container assembly.

[0038] In further embodiments, one or more components of the fitting may be formed from layers of TPE / LDPE / TPE or similar variations such that the TPE parts are utilized as a sealing material with the mating parts. Thus, in various embodiments, this allows for a valve assembly made exclusively of polypropylene. Additionally, the fitting bosses of the valve assembly may be formed from TPE that sealingly engage with the LDPE fitting such that a radial seal of the hard material to the soft material is provided. The fitting may alternatively or additionally be stamped / die cut from the TPE material, with the geometric substructure providing flexure as needed and providing a stiffer portion for support stiffness, but where stiffness is needed for sealing and flexure is needed to reduce user assembly forces. The valve assembly may alternatively or additionally include an overmolded TPE surface that interfaces and seals against the fitting of the container. Additionally, the flat fitting may include a surface that seals with the TPE surface of the valve assembly, this combination creating a seal when the system door is closed over the part. A TPE cylindrical part 297 can also be placed between the fittings (see FIG. 15N), where initially there is an annular space about the TPE part 297 until the fitting is placed into the TPE part, thereby creating the necessary seal and closing the space. Also, in another embodiment, a Santoprene valve assembly part is provided that naturally rests with a gap therein, and when a second part is inserted, the Santoprene part is pushed outward to close the gap and create a seal.

[0039] In one particular approach (FIGS. 16A-B), a container assembly 120 is provided that is configured with a rubber plug 308 sized and shaped to be received within a fitting 180 attached or formed on a neck portion 128 of the container assembly 120. The neck assembly 128 is folded so that the plug 308 is sealingly received within the fitting 180. In a related approach shown in FIGS. 17A-B, the container assembly 120 embodies a spout structure 150 with a rubber ring 309 that is configured to seal against an exterior surface of the fitting 180 when the spout 150 is folded into place. It should be understood that various locations of the plug and fitting are possible. For example, the plug may alternatively or additionally be located on the body of the container detached from the neck portion. In these and other approaches to fittings, the interior and / or exterior structure of the mating parts may take on unique and / or non-circular mating surfaces and configurations to facilitate proper alignment between the parts. Additionally, one or more of the fitting and plug may include an annular snap that engages with an undercut ledge on its mating component.

[0040] As shown in FIG. 18, the neck 128 of the container assembly 120 can also be used to seal the fitting further comprising an adhesive foam pad 310 including a removable adhesive liner, where the neck 128 folds over the foam pad 310 to form a seal. Additionally, in yet another embodiment (FIGS. 19A-C), various foldable clips 320, 330 can be provided to engage and seal the container assembly 120 when closed. Further (FIG. 20), a separate cap 340 can be provided to mate with the fitting 120 in addition to or instead to act as a seal.

[0041] 21A-B, a mating connector 350, 360 is shown configured to provide a mating structure between two container assemblies 120 so that breast milk can be transferred from one container to another. As shown in FIG. 21A, the mating connector 350 is sized and shaped to sealingly mate near the exterior surface of the fitting 180 and further includes a cap 352 configured to close the mating connector. The mating connector 360 shown in FIG. 21B may include a one-way valve 362 that acts as a seal and may be sized and shaped to fit inside the fitting. Alternatively, the connector may lack a one-way valve and thus define a structure for transferring liquid between the container assemblies. These structures may be separate parts or may be integrated with existing system components such as fittings. By using such an arrangement, a user of the breast milk pumping system may then combine breast milk from multiple containers, which helps reduce the number of containers requiring storage and allows the user to store a certain amount of breast milk in a container to facilitate later feeding.

[0042] 22A-B, further embodiments of a container assembly 120 are shown having a fitting 180 and including plugs 370, 380 configured to be received within the fitting 180. In a first approach (FIG. 22A), the fitting 180 and plug 370 are placed within an oval shaped opening 372 formed in the container assembly 120 and attached to the container assembly 120. In a second approach (FIG. 22B), two separate holes 382 are formed in the container assembly 120 and sized to receive the fitting 180 and plug 380, respectively.

[0043] 23A-B show a container assembly 120 including flat fittings 390, 400. Such flat fittings 390, 400 are characterized by having simple low profile structures configured similarly to the embodiments described above such that the structures are positioned between layers of the container. Through holes 392, 402 formed in the fittings provide access to the interior of the container assembly 120.

[0044] As mentioned above, the container assemblies disclosed herein may be disposable or reusable and may be formed partially or entirely from one or more of rigid or flexible materials. Additionally, the container assembly may include a breast interface structure and thus replace or incorporate a flange or may be attached to a flange of a breast milk pumping system. Thus, in various embodiments, the container assembly is configured to be assembled with a breast pump, and the pump is configured to recognize its presence prior to pumping, such as via a Hall effect sensor or valve structure. In certain approaches, the container assembly is compatible with multiple flanges and sizes. Each feature disclosed below may define additional or alternative structures for each disclosed container assembly. Referring now to Figures 24A-B, a reusable container assembly 450 formed from multiple pieces is shown. In a first approach, the container assembly 450 is defined by a first part 462 configured to be retained within the assembled breast pump system (see FIG. 1A ) and a second part 464 each mating with a funnel 466, the second part 464 and the funnel defining the outer surface of the breast milk pumping system. The funnel 466 includes a nipple receiver 468, which replaces the flange presented in connection with the previously disclosed embodiment. The outer surface of the nipple receiver 468 of the funnel 466 is configured to be removable from the first and second parts 462, 464. The outer surface of the nipple receiver 468 is sized and shaped to seal with an opening formed in the first part 462, and a generally circular base 469 of the funnel 466 seals with an opening formed in the second part 464, the three components cooperating to thereby define a housing for receiving breast milk pumped by the breast milk pumping system. The container assembly 450 is generally split longitudinally with a first part 462 connected to a second part 464 by a weld or seal along the periphery of the two parts that matches the outer shell of the milking system. The assembly may alternatively or additionally include a removable plug 470 that facilitates access to the interior of the container assembly 450 for cleaning and / or pouring collected breast milk therefrom.The removable plug 470, or alternatively its corresponding structure in an assembly lacking a plug, includes an opening 472 sized and shaped to mate or otherwise receive a flex conduit or tube and associated fitting (see FIG. 2A). This opening 472 may include a fitting (not shown) that mates with the flex conduit. A second end of the fitting is sized and shaped to sealingly engage with a nipple, or an extension 473 that protrudes from the exterior of the nipple receiving portion. In its assembled configuration, the container assembly 450 can be stored for later use, and when disassembled, the parts can be conveniently cleaned for future use. In a related approach (FIG. 24C), the funnel 466 has a generally oval base 469 that mates with a corresponding structure or opening in the second part 464. The oval base assists the user in properly assembling the funnel 466 to the first and second parts 462, 464.

[0045] 25A-B, another approach to a reusable container assembly 480 is shown. Here, the container assembly 480 is generally split laterally and includes a first part 482 defining a top of the container assembly 480 and a second part 484 defining a bottom of the container assembly 480 that seals with or is welded to the first part 482. The assembly further includes a funnel 486 that mates with the first and second parts 482, 484 in the manner described above to create a container for holding breast milk and a container that mates to complete the breast pump assembly. A plug 488 may further be provided to removably mate with the second part 484 to provide access to the interior of the container assembly. Additionally, as described above, the container assembly is configured to be sized and shaped to sealingly mate with a flex conduit or other structure through which breast milk is to be pumped. As shown in FIG. 26, the structure mating the first and second parts 482, 484 may include a sealing surface 489. In one approach, this structure may be more rigid than the remainder of the first part 482 to provide additional strength for a robust mating or attachment. Alternative approaches to this and other connections to the fitting of the container assembly may include a Boston shaker connection, a hinge and latch arrangement, or a detent and sealing engagement. Additionally, herein, the funnel and second part may define a unitary structure or multiple parts.

[0046] 27A-B, the container assembly 490 may alternatively be formed from two pieces, a body 492 and a funnel 494 that sealingly mates with the body 492. The funnel includes a base 495 that mates with an opening formed in a first exterior of the body 492 and an exterior surface where a nipple receiving portion of the funnel 494 mates with an opening formed in a second interior of the body 492 to form a container for receiving breast milk pumped by the breast milk pumping system. When assembled, the container assembly 490 is configured such that the periphery of the container assembly mates with the remainder of the breast milk pumping assembly to complete the breast milk pumping system. Additionally, as before, the container assembly 490 includes structure to mate with and receive a conduit that transports breast milk to the container assembly 490, and the funnel 494 and the first exterior of the body 492 define structure that engages the user's breast. 28, the container assembly 490 may further embody a funnel 494 that includes a tab 496 that mates with a recess 497 formed in the body 492. This structural arrangement aids a user in properly assembling the funnel 494 to the body 492. In yet another approach (FIG. 29), the body 492 may be formed from two pieces, a bottom 502 and a top 504 that mate along scalloped edges, where the top 504 may be removable and sealed to the bottom 502.

[0047] As shown in Figures 30A-B, the container assembly 510 may be defined by a flange 512 configured to mate with a cover or lid 514 that includes an elastomeric region for a bi-stable port region 516. There is a seal structure along the perimeter of engagement between the flange 512 and the lid 514. The lid may further include a strike plate or hall effect actuator member 518 that facilitates notification that the container assembly is connected to the remainder of a breast milk pumping system. As best shown in Figure 30A, the elastomeric region 516 may be disposed in its expanded configuration to present a pour structure that may have a cap 519 for storing breast milk received within the container assembly 510. The elastomeric region 516 further includes structure to mate with a conduit that pumps breast milk into the container assembly 510.

[0048] In a related approach (FIG. 31), the container assembly 520 is embodied in a two-part assembly. A first part 522 incorporates the flange and breast-engaging structure and the bottom of the container assembly 520. A separate, removable cap and valve assembly 524 is configured to mate with the first part to complete the container assembly 520. It is the cap and valve assembly 524 that connects to a conduit that delivers pumped breast milk to the container assembly.

[0049] Also, as shown in Fig. 32A-B, the container assembly 530 may also include a flange 532 configured to mate with a cover or lid 534 including an overmolded seal 535 along a connecting edge, and a cap 536 with an overmolded seal 535. Various configurations of the cap are also contemplated. Furthermore, in a related manner, beer wax can be used as the material of the cover of this embodiment, or as other manners of container assembly by cutting or forming the beer wax into various desired shapes and circumferences, and such material can be washed and reused. Alternatively, the beer wax material may be employed to form the entire container. In either manner, the ends of the beer wax material are compressed together to form a seal to form the container assembly, and the same can define a reusable device.

[0050] Various additional embodiments of container assemblies are shown in Figures 33A-F and include features that can be incorporated into any of the disclosed approaches to container assemblies. For example, as shown in Figures 33A-B, a container assembly 540 may include a body 542 and a cap 544, where the body 542 resembles a water bottle with a pouring opening 545 configured on the top of the body 542. The body 542 also includes a breast-engaging structure and a nipple receiver. The cap 544 completes the assembly and includes both structure intended to mate with a conduit that carries pumped breast milk and a pathway from such connection to a fill hole 546 formed on the top of the body. As with the above-described embodiments, the completed container assembly completes a breast milk pumping system and is accordingly configured to detachably mate therewith.

[0051] 33C-D, the container assembly 550 may additionally or alternatively include an upper portion 552 and a lower portion 554. On one side of the container assembly 550, the upper and lower portions cooperate to form a flange for receiving a breast, while on the opposite side, the lower portion includes structure defining a nipple-receiving portion and an outer portion thereof 555. The container assembly 550 further includes a hoop 556 extending from the upper portion 552, the hoop 556 being sized, shaped and configured to be disposed near the exterior of the nipple receiving portion 555 so as to thus act as an attachment member between the components.

[0052] 33E and 33F, further features that may be incorporated into the container assembly are presented. Notably, FIG. 33E shows a container assembly 560 including a flap 562 extending from the periphery of a first part 564 of the container assembly, sized and shaped to fit into a recess formed in a second part 566 of the container assembly. In this approach, the first part 564 includes a structure that functions as a flange and includes a nipple receiving portion 567. It is contemplated that various sizes of this first part 564 may be provided to accommodate different breast sizes. The two-part container approach 570 depicted in FIG. 33F features a pair of foldable arms 572 extending from the periphery of a cover member 574, however, any of the container assembly parts may include such structure.

[0053] Additionally, a rotating cover 580 (FIG. 34) may be attached to the exterior surface of any of the disclosed container assemblies. When in the closed configuration, the cover 580 lies flush with the exterior surface of the container assembly 582, sealing the access into the assembly. The container assembly 590 may also, or instead, include a locking ring 592 (FIGS. 35A-B) that slides and rotates against the exterior surface of the nipple receiver 594. A half turn of the locking ring 592 (FIG. 35A) can, for example, draw mating parts of the container assembly 590 together for assembly purposes. In a related approach, the locking ring 592 includes tabs 593 that lock over projections 595 extending from the container assembly to effect locking of the flange to the container assembly.

[0054] As shown in Figs. 36A-I, 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 to mate with a conduit containing pumped breast milk. As shown in Fig. 36A, the reusable bag container assembly 600 may be configured to occupy the entire available space within the breast milk pumping system. As shown in Figs. 36B-D, the container assembly 600 may additionally or alternatively include an open or partially open bottom end 602 with buttons, snaps, magnets and / or Velcro 604 to seal the assembly in a closed configuration. Once placed inside the breast milk pumping system, the bottom portion 602 of the container assembly folds on itself and closes employing a sealing means. In a related method (Figs. 36E-F), an upper portion 610 of the container assembly 600 folds to seal the container 600. As shown, the top portion 610 includes a hole 612 sized and shaped to fit over a fitting 614 configured within the container. As shown in Figs. 36G-H, the container assembly 600 may also include a removable cap 618 that provides access to the interior of the assembly and a convenient port for pouring collected breast milk. Fig. 361 shows a bag container assembly 630 that forms a cylinder that surrounds the internal structure of the breast milk pumping system. One end of the assembly is configured with a replaceable clamp 632 that seals the structure in a closed configuration.

[0055] FIG. 36J shows a reusable bag container assembly 640 that includes a sharp edge with a zip-lock seal structure 642. Such structure conveniently seals the assembly 640 for use in a breast milk pumping system and for storage, if desired. The contents of the assembly 640 can be removed by separating the zip-lock seal. Additionally, as shown in FIGS. 37A-C, a one-way valve, pour stopper device 650 can be incorporated into one or more of the container assemblies described herein. The device includes a strap 652 that connects a one-way valve portion 654 to a spout stopper portion 656. A gripping tab 658 is also provided at the terminal end of the device. As best shown in FIGS. 37A-B, the device 650 can be attached to a flange or other container assembly and serves as both a controlled inlet and a port for pouring collected breast milk.

[0056] With reference to Figs. 38A-G, various alternative approaches to the spout 660 of the container assembly are shown. The container assembly may have a cap for sealing the spout during pumping, transport, and storage. The cap may be of various shapes, sizes, and configured to mate with spouts located at various positions on the container assembly. Thus, the spout 660 may exhibit different shapes, each capable of accommodating a brush or other cleaning device for easily cleaning the interior of the container assembly. A lip 662 formed near the spout 660 facilitates controlled transfer of breast milk and minimizes spillage. Furthermore, certain spout shapes allow for pouring from multiple directions, with and without a pump assembly. Thus, the spout may be offset to one side, for example, or may be centered on the top surface of the container.

[0057] Various other approaches to the cap 670 may also be included to seal a spout formed in the container assembly and / or various integral spouts formed or attached to the container assembly (see Figs. 39A-G). The cap may be freestanding, tethered, foldable, snapped onto the container assembly, or overmolded. Furthermore, in addition to sealing the spout, the cap may also help provide a lip or spout to facilitate transfer of breast milk out of the container. That is, the cap 670 may be embodied as a tie 672 (Fig. 39A), the spout may be embodied as a flip-up straw 674 (Fig. 39B) or may include one or more of an internal spout 676 (Fig. 39C), a cap with a lip 678 (Fig. 39D), a fold-over spout 680 (Figs. 39E-F), a capped spout 682 (Fig. 39G), or a pull-out spout 684 (Fig. 39H).

[0058] Additional approaches for ventilating the container assembly are shown in Figures 40A-K. In one approach (Figure 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 spout or may define a separate structure. Alternatively, the through hole may be incorporated into the cap of the spout. It may further have a structure that functions to open and close the opening to allow release of built-up air pressure. Thus, the closure structure may be embodied as a sliding door structure 692 (Figure 40B), a pivoting or rotating door 694 (Figures 40C-D), a rotating or twisting cam structure 696 (Figure 40E), or a twistable cap 698 (Figure 40F). Alternatively or in addition, the ventilation structure may include a valve 702 (FIG. 40G), such as an umbrella valve, duckbill valve, or diaphragm arrangement, integrated into the container, such as a spout or elsewhere, allowing air pressure to be released as the container fills with fluid. This approach also serves to minimize the possibility of liquid spilling as the user moves about. A cap may further be provided to seal the valve and define a plug or any of the structures described.

[0059] Further, as shown in FIG. 40H, two valves 702 may be integrated with the container, one located at the top of the container exhibiting a lower crack pressure, allowing air to be released therefrom during a pumping session. Here, the user caps the top valve when completing a pumping session, and then performs a flip to finish. The bottom valve has a higher crack pressure that allows air to be released during the flip to finish when the container is inverted. It should be recognized that instead of the valves, a porous PTFE membrane may be employed for the ventilation function, where the membrane allows air flow but prevents fluid flow. Also, the membrane may be hydrophobic and / or oleophobic, and the membrane may be located near the top and bottom of the container such that air is released not only during standard pumping, but also during the flip to finish. Furthermore, a hydrophilic PTFE membrane may also be of single use, where the user applies a PTFE membrane stick over the spout at the beginning of pumping. Once pumping is completed, the liquid comes into contact with the PTFE membrane, which acts as a cap to seal the membrane closed until the user is ready to transfer the breast milk to another container.

[0060] In one embodiment, a single valve may be provided near the top of the container that naturally remains open to vent, but closes in response to increased pressure as the liquid level rises. In the single vent approach, the container may further include an internal diaphragm that expands with increased pressure when air or milk is added during the final stages of the pumping process, such as flipping to finish, thus eliminating the need for a second valve. As shown in FIG. 401, the container assembly may additionally or alternatively include one or more elastic balls 704 configured to ride within the channel 706 and open to the outside. As fluid enters the container, air is released through the channel. Upon flipping to finish, the weight of the fluid pushes against the ball 704, sealing the opening to the channel 706.

[0061] As shown in FIG 40J, the valve can be designed into the cap 710, which includes an elastomeric layer that includes a diaphragm or duckbill valve 712. After pumping, the user closes the cap 710 to seal over the valve 712. As shown in FIG 40K, the container may additionally or alternatively include an internal channel 720 that functions to allow air to be excluded as the container fills with fluid. Air enters the channel 720 at the top and exits at the bottom of the container. When the user performs a finishing flip, the container is inverted, thereby allowing the channel 720 to fill with fluid.
