[0048] In the following description of various examples and components of this disclosure, reference is made to the accompanying drawings, which form part of this disclosure, and which illustrate by way of illustration various exemplary structures and environments in which aspects of this disclosure may be practiced. It should be understood that other structures and environments may be utilized without departing from the scope of this disclosure, and structural and functional modifications may be made according to the structures and methods specifically described.

[0049] Furthermore, although various exemplary features and elements may be described in this specification using terms such as “front,” “rear,” “top,” “base,” “bottom,” “side,” “forward,” and “backward,” these terms are used herein for simplicity purposes, for example, based on the exemplary orientations shown in the figures or orientations in conventional use. Nothing in this specification should be construed as requiring a specific three-dimensional or spatial orientation of the structure without departing from the scope of the claims.

[0050] Figure 1 depicts an isometric view of a lid assembly 100 removably coupled to a container 105 according to one or more aspects described herein. Container 105 is an exemplary container to which the lid assembly 100 may be configured to be removably coupled. Thus, container 105 may be configured to store a volume of liquid, and lid assembly 100 may be configured to seal the opening of container 105.

[0051] Figures 2A and 2B depict isometric views of the cap assembly 100 in a closed configuration and an open configuration, respectively. The cap assembly 100 generally includes a slider mechanism 102 configured to move between a closed position (shown in Figure 2A) and an open position (shown in Figure 2B) to selectively close or open a first opening 104 through which liquid stored in the container 105 is configured to flow. Details of the slider mechanism 102 are discussed further in conjunction with the preceding figures. Additionally, the cap assembly 100 may include a sidewall 106 that may define a recess 108 for placing a gasket 110. Thus, the gasket 110 can provide a seal between the cap assembly 100 and the container 105. However, other sealing methods for sealing the cap assembly 100 to the container 105 are also contemplated. The cap assembly 100 may also include an edge 112 for engaging the opening of the container 105. Edge 112 may also include top wall 114 and gripping element 116 and / or optional lid tabs (not shown) extending from top wall 114 to assist the user in removing lid assembly 100 from container 105.

[0052] The cover assembly 100 may also include an intermediate wall 118 extending below edge 112. The top surface 120 of the intermediate wall 118 may define a recess 122 for receiving the slider mechanism 102. In one example, when the slider mechanism 102 is in… Figure 2A When moved between the closed position shown in Figure 2B and the open position shown in Figure 2B, the recess 122 may define a guide channel. As shown in Figure 2B, a first opening 104 for drinking or pouring liquid from a container may also be formed in the recess 122. The recess 122 may also include a second opening 124, which will be described in further detail in conjunction with Figure 5A. An engaging portion 126 may extend from the top surface 120 of the intermediate wall 118 into the recess 122. This engaging portion 126 may be configured to, when in the open position… Figure 2B The open position shown is adjacent to the slider mechanism 102 to prevent liquid from being compressed between the slider mechanism 102 and the end wall 128 of the recess 122. Otherwise, liquid may accumulate in the recess 122 as the user drinks or pours liquid from the first opening 104, which may cause liquid splashing.

[0053] Figure 3 schematically depicts an exploded isometric view of the cover assembly 100 according to one or more aspects described herein. In particular, Figure 3 schematically depicts multiple elements constituting the slider mechanism 102, as shown in conjunction with Figure 2A and... Figure 2BAs discussed, the slider mechanism 102 may include an upper slider 130 configured to be positioned within a recess 122 on the top surface 120 of the intermediate wall 118. The upper slider 130 may include an upper magnet 132 encapsulated therein. In one example, the upper magnet 132 may be encapsulated within a cavity in the upper slider 130 and may be overmolded with a polymer-overmolded plug element 134. Other or alternative encapsulation methods may be used to secure the upper magnet 132 within the upper slider 130 without departing from the scope of these disclosures. Additionally, the upper slider magnet 132 may be formed of any suitable ferromagnetic or other magnetic material. The upper slider 130 is discussed in further detail with reference to Figures 7A and 7B.

[0054] Additionally, the slider mechanism 102 may include a lower slider 136 configured to be positioned adjacent to the bottom surface 138 of the intermediate wall 118 (shown in FIG. 5B). The lower slider 136 may include a lower magnet 140 encapsulated therein. In one example, the lower slider magnet 140 may be encapsulated within a cavity in the lower slider 136 and may be overmolded with a polymer-overmolded plug element 142. Additionally, the slider mechanism 102 may include a lower washer 144 configured to extend around the periphery of the lower slider 136. The lower slider 136 is described in further detail with reference to FIGS. 6A and 6B.

[0055] In one example, the magnetic attraction between the upper sliding magnet 132 and the lower sliding magnet 140 magnetically couples the upper sliding element 130 to the lower sliding element 136 on the intermediate wall 118. Therefore, manually actuating the upper sliding element 130 on the top surface 6 of the intermediate wall 118 causes both the upper sliding element 130 and the lower sliding element 136 to slide.

[0056] Figure 4 schematically depicts a cross-sectional view of the cover assembly 100 according to one or more aspects described herein. As shown, the slider mechanism 102 is in a closed configuration such that the first opening 104 is sealed by the slider mechanism 102. In one example, the lower sliding magnet 140 may have a centrally hollow cylindrical geometry. Similarly, the lower sliding magnet 140 may be otherwise described as a toroidal magnet extending around a central tube 146 through the overmolded plug element 142 and the lower slider 136. In another example, the lower sliding magnet 140 may have a solid cylindrical geometry.

[0057] Figures 5A and 5B depict isometric views of the cover assembly 100 without the slider mechanism 102. Specifically, Figure 5A depicts a view of the top surface 120 of the intermediate wall 118, and Figure 5B depicts a view of the bottom surface 138 of the intermediate wall 118. As shown, the cover mechanism 100 includes a first opening 104 and a second opening 124. In one example, a portion of the slider mechanism 102 is configured to extend through the second opening 124 when the upper slider 130 is magnetically coupled to the lower slider 136.

[0058] The second opening 124 may include engagement portions 148 extending from the intermediate wall 118 into the second opening 124. When the slider mechanism 102 is in the closed position shown in FIG. 2A, these engagement portions 148 are configured to be received in a channel 150 (see FIG. 6A) extending along a portion of the central tube 146 of the lower slider 136. Therefore, the engagement portions 148 are configured to provide an interference fit to prevent the slider mechanism 102 from being unintentionally moved, thereby unintentionally unlocking the first opening 104. In one example, the slider mechanism 102 may be configured to lock in the open and / or closed configurations shown in FIG. 2A and FIG. 2B. It is further contemplated that, in addition to the engagement portions 148, a locking mechanism may be used to further prevent the slider mechanism 102 from being unintentionally moved.

[0059] Figure 5B depicts the bottom surface 138 of the intermediate wall 118. Thus, as shown, the bottom surface 138 defines a first inclined feature 152 on a first side of the second opening 124. The first inclined feature 152 has ridge surfaces 154 spaced apart between two groove-like recesses 156. Similarly, a second inclined feature 158 is positioned on a second side of the second opening 124. The second inclined feature 158 includes ridge surfaces 160 spaced apart between two groove-like recesses 162.

[0060] Additionally, the cap assembly 100 includes a recessed portion 161 extending into an inner surface 163 of a sidewall that extends below the bottom surface 138 of the intermediate wall 118. Therefore, when the slider mechanism 102 is in the closed position shown in FIG. 2A, the recessed portion 161 accommodates a portion of the lower slider 136. The cap assembly 100 also includes a recessed venting portion 165, such that the geometry of the recessed venting portion 165 allows air to flow into the container 105 when liquid is poured out from the first opening 104.

[0061] Figures 6A and 6B depict isometric views of a lower slider 136 according to one or more aspects described herein. Thus, the lower slider 136 includes an inner surface 164 configured to be positioned adjacent to the bottom surface 138 of the intermediate wall 118. The inner surface 164 includes a lower slider ramp 166. The lower slider ramp 166 is configured to be received in one of the groove-like recesses of each of the first inclined features 152 and the second inclined features 158. Similarly, the lower slider ramp 166 is configured to slide on the first inclined features 152 and the second inclined features 158 as the slider mechanism 102 slides between the open and closed configurations. When the slider mechanism 102 translates between the open and closed configurations, the lower slider ramp 166 will abut ridge surfaces 154 and 160. Furthermore, because the ridge surfaces 154 and 160 are raised relative to the groove-like recesses on either side of the ridge surfaces 154 and 160, this will further space the upper slider 130 and the lower slider 136 apart from each other. Similarly, because the magnetic force between the upper slider magnet 132 and the lower slider magnet 140 is inversely proportional to the square of the distance between them, the magnetic attraction will decrease when the lower slider slope 166 is adjacent to the ridge surfaces 154 and 160. In one example, this decrease in magnetic force will allow the slider mechanism 102 to move smoothly between the open and closed positions. Furthermore, when the lower slider slope 166 is positioned within the groove-like recesses of the first inclined feature 152 and the second inclined feature 158, the relatively short distance between the upper slider magnet 132 and the lower slider magnet 140 will create a relatively strong magnetic attraction that is used to secure the slider mechanism 102 in the open or closed configuration.

[0062] It should be noted that the lower slider 136 and the upper slider 130 are symmetrical about the vertical axis to allow the slider mechanism to be mounted in the cover assembly 100 in any of four different ways. Additionally, the lower slider 136 includes a central tube 146 extending from the inner surface 164. Further, the central tube 146 includes a tab lug 168 configured to extend through the second opening 124. The lower slider 136 further includes a channel 170 configured to receive a portion of the lower washer 144. Additionally, the lower slider 136 includes lower ventilation channels 171a and 171b. Thus, when the slider mechanism 102 is in the open configuration, a portion of the lower slider 136 extends over a portion of the recessed ventilation portion 165. Further, one of the lower ventilation channels 171a or 171b is positioned over the recessed ventilation portion 165, thereby establishing a channel through which air can enter the internal cavity of the container 105 from the slider mechanism 102.

[0063] Figure 6B depicts an isometric view of the outer surface 172 of the lower slider 136. In one example, a knob 174 (otherwise referred to as a finger-like protrusion 174) extends from the outer surface 172. This knob 174 is configured to be gripped by a user to mount the slider mechanism 102 into the cover assembly 100. This mounting process is described in further detail with reference to Figure 12.

[0064] Figures 7A and 7B depict isometric views of the upper slider 130. The upper slider 130 may include two symmetrical flanges 176a and 176b, both configured to selectively cover and seal the first opening 104 for pouring liquid from the container and the second opening 124 into the recess 122 (otherwise referred to as the guide channel 122). A tab or handle 178 is configured to be gripped by a user to selectively move the upper slider 130, thereby moving the slider mechanism 102 to an open position to open the first opening 104 on the cap assembly 100 or a closed position to cover the first opening 104 on the cap assembly 100. The tab or handle 178 may include two inwardly tapering portions 180a and 180b for gripping purposes.

[0065] Figure 7B depicts a view of the inner side 182 of the upper slider 130. Therefore, the upper slider 130 includes upper ventilation channels 184a and 184b. Thus, when the slider mechanism 102 is in the open configuration, the ventilation path is partially formed by a portion of the lower slider 136 extending above a portion of the recessed ventilation portion 165. Additionally, one of the lower ventilation channels 171a or 171b is positioned above the recessed ventilation portion 165, thereby establishing a channel through which air can enter the internal cavity of the container 105 from the slider mechanism 102. When the upper ventilation channels 184a and 184b allow air to enter the slider mechanism 102 from the external environment, a ventilation path is completed between the external environment and the internal cavity of the container 105. The upper slider recesses 186a and 186b are configured to receive a portion of the tab lug 168 of the lower slider 136.

[0066] Figures 8A and 8B depict isometric and partial cross-sectional views of the lower washer 144 according to one or more aspects described herein. Thus, when the slider mechanism 102 is in the closed configuration shown in Figure 2A, the lower washer 144 is configured to seal the first opening 104. Additionally, the lower washer 144 is configured to seal the second opening 124. In one example, the inner surface 188 of the lower washer 144 is configured to be positioned above the outer surface 172 of the lower slider 136. The opening 190 in the lower washer 144 is configured to allow the knob 174 of the lower slider 136 to extend through. In one example, the lower washer 144 may be made of silicone. However, other or alternative polymeric materials may be used without departing from the scope of this disclosure.

[0067] The cross-sectional view of Figure 8B shows the spring feature 192 of the lower washer 144. Therefore, the spring feature 192 allows the seal formed by the washer 144 to move and remain in contact with the bottom surface 138 of the intermediate wall 118. Thus, in the open or closed configuration, a relatively high magnetic force causes the lower slider 136 to compress the spring feature 192 of the lower washer 144 against the bottom surface 138 of the intermediate wall 118. Further, when the lower slider ramp 166 is positioned on the ridge surfaces 154 and 160, and the magnetic force is relatively low, and the lower slider 136 moves away from the bottom surface 138, the spring feature 192 extends outward toward the bottom surface 138 and remains in contact with the bottom surface 138 to maintain the seal of the lower washer 144 on the bottom surface 138.

[0068] Figures 9A and 9B schematically depict cross-sectional views of the cover assembly 100 in its closed configuration. As shown, a slider mechanism 102, including an upper slider 130 and a lower slider 136, seals the first opening 104. Figure 9B depicts a more detailed view of a portion of the cross-section of Figure 9A. Thus, Figure 9B depicts a portion of the lower slider 136 and the lower washer 144 being received in a recess 161 of the cover assembly 100.

[0069] Figures 10A and 10B schematically depict cross-sectional views of the cap assembly 100 in its open configuration. As shown, the first opening 104 is fully opened by a slider mechanism 102, which includes an upper slider 130 and a lower slider 136. Figure 10B schematically depicts a more detailed view of a portion of the cross-section of Figure 10A. In particular, Figure 10B depicts a portion of a lower washer 144 that has slid over a portion of a recessed vent 165. The overlap of the portion of the lower washer 144 over the portion of the recessed vent 165 forms a gap 192 through which air can enter the container 105 when liquid is poured out of the first opening 104.

[0070] Figures 11A and 11B schematically depict cross-sectional views of the cover assembly 100 in a partially open configuration. As shown, the first opening 104 is partially opened by a slider mechanism 102, which includes an upper slider 130 and a lower slider 136. Figure 11B schematically depicts a more detailed view of a portion of the cross-section of Figure 11A. In particular, Figure 11B shows a gap 196, or interval 196, between the upper slider 130 and the lower slider 136. As previously described, this gap 196 is formed by the lower slider ramp 166 adjacent to the ridge surfaces 154 and 160.

[0071] Figures 12A to 12D depict various steps for disassembling the slider mechanism 102 and removing it from the cover assembly 100. As previously described, the slider mechanism 102 includes an upper slider 130 and a lower slider 136. Further, the upper slider includes an upper slider magnet 132, and the lower slider 136 includes a lower slider magnet 140 and a lower washer 144. Figure 12A depicts the cover assembly 100 with the slider mechanism 102 fully installed and in an open configuration. To remove the slider mechanism, for example, to facilitate cleaning the cover assembly 100, the upper slider 130 can be manually lifted from the top surface 120. Figure 12B depicts the upper slider 130 after removal from the top surface 120. Once the upper slider 130 is removed, the lower slider 136 no longer abuts against the bottom surface 138 by the magnetic attraction between the upper slider magnet 132 and the lower slider magnet 140. However, when the tab 168 extends through the second opening 124 and grips a portion of the top surface 120, the tab 168 prevents the sliding member 136 from falling into the container 105.

[0072] To remove the lower slider 136 from the cover assembly 100, the lower slider 136 is rotated 90 degrees so that the tab lug 168 can pass through the second opening 124. Figure 12D depicts the upper slider 130 and the lower slider 136 completely removed from the cover assembly 100.

[0073] Figure 13 schematically depicts a cross-sectional view of a portion of the cap assembly 100 connected to the container 105. In one example, the cap assembly 100 is resealably connected to the container 105 by threaded elements on both the sidewall 106 of the cap assembly 100 and the sidewall 202 of the container 105. Elements 204 and 206 are threads on the sidewalls 106 and 202, respectively. Furthermore, it is contemplated that any thread geometry can be used to secure the cap assembly 100 to the container 105 without departing from the scope of these disclosures. Alternatively, the various cap assembly 100 structures described in this disclosure can be implemented without a threaded connection between the cap assembly 100 and the container 105. In one example, the cap assembly 100 can be secured to the container 105 by means of an interference fit or the like.

[0074] Figures 14A to 14E depict alternative embodiments of a slider mechanism with alternative disassembly mechanisms. Therefore, Figure 14A depicts an isometric view of a cover assembly 300 including a slider mechanism 301. The cover assembly 300 may be similar to the cover assembly 100, and the slider mechanism 301 may be similar to the slider mechanism 102. The slider mechanism 301 may include an upper slider 302 similar to the upper slider 130, and a lower slider 306 similar to the lower slider 136. To disassemble the slider mechanism, the upper slider 302 can be manually removed from the cover assembly 300. Similar to the lower slider 136, the lower slider 306 may include a tab lug 308 to prevent the lower slider 306 from falling into the container when the upper slider 302 is removed. However, in order to remove the lower slider 306 from the cover assembly 300, the lower slider 306 slides to the position shown in FIG. 14C, such that the geometry of the tab lug 308 aligns with the geometry of the opening 309 in the intermediate wall 310 of the cover assembly 300. When positioned in the configuration depicted in FIG. 14C, the lower slider 306 can pass through the opening 309, as depicted in FIG. 14D. FIG. 14E depicts the upper slider 302 and the lower slider 306 completely removed from the cover assembly 300.

[0075] Figure 15 illustrates another embodiment of a lid assembly 1500 configured to be removably coupled to a container 1505 according to one or more aspects described herein. Lid assembly 1500 and container 1505 are interchangeable with lid assembly 100 and container 105, such that lid assembly 1500 can be removably coupled to container 105 and lid assembly 100 can be removably coupled to container 1505. Lid assembly 1500 may include a plurality of elements similar to lid assembly 100, such that if those features are marked with the first two digits “15” and the last two digits are the same as those described with respect to lid assembly 100, the reference numerals used to describe the features of lid assembly 1500 may include elements with similar features described with respect to lid assembly 100. For example, slider mechanism 102 described with respect to lid assembly 100 may be similar to slider mechanism 1502, since both elements are indicated by a designation ending in “02”. As can be noted in the preceding description, the elements of cover assembly 1500 have additional, alternative, or distinguishing features relative to the elements of cover assembly 100.

[0076] Figure 16 schematically depicts an exploded view of several elements of a cap assembly 1500 according to one or more aspects described herein. The cap assembly 1500 generally includes a slider mechanism 1502 configured to move between a closed position (shown in Figure 15) and an open position to selectively close or open a first opening 1504 through which liquid stored in the container 1505 is configured to flow. Additionally, the cap assembly 1500 may include a sidewall 1506 that may define a recess 1508 for placing a gasket 1510. Thus, the gasket 1510 may provide a seal between the cap assembly 1500 and the container 1505. However, other sealing methods for sealing the cap assembly 1500 to the container 1505 are also contemplated. The cap assembly 1500 may also include an edge 1512 for engaging the opening of the container 1505. Edge 1512 may include a top wall 1514 and gripping elements 1616 extending from the top wall 1514 to assist a user in removing the lid assembly 1500 from the container 1505. As shown, gripping elements 1616 include a plurality of recessed elements extending along the vertical wall 1602 of edge 1512. It is contemplated that these gripping elements 1616 may have any recess geometry (depth, spacing, etc.) and may be made of the same or different materials as the elements of edge 1512. Additionally or alternatively, the gripping elements may include gripping surface geometries different from the depicted recesses, such as pits, protrusions, or relatively smooth gripping surfaces.

[0077] The cap assembly 1500 may include a cap 1501 having a central wall 1518 extending below an edge 1512. The top surface 1520 of the central wall 1518 may define a recess 1522 for receiving a slider mechanism 1502. In one example, the recess 1522 may define a guide channel as the slider mechanism 1502 moves between a closed position and an open position as shown in FIG. 15. A first opening 1504 for drinking or pouring liquid from the container may also be formed in the recess 1522. The recess 1522 may also include a second opening 1524. An engaging portion 1526 may extend from the top surface 1520 of the central wall 1518 into the recess 1522. The engaging portion 1526 may be configured to abut the slider mechanism 1502 when in the open position to prevent liquid from being compressed between the slider mechanism 1502 and the end wall 1528 of the recess 1522. Otherwise, liquid may accumulate in the recess 1522 as the user drinks or pours liquid from the first opening 1504, which could lead to liquid splashing.

[0078] The slider mechanism 1502 may include an upper slider 1530 configured to be positioned within a recess 1522 on the top surface 1520 of the intermediate wall 118. The upper slider 1530 may include an upper magnet encapsulated therein. In one example, the upper magnet may be encapsulated within a cavity in the upper slider 1530 and may be overmolded with a polymer-overmolded plug element. Other or alternative encapsulation methods may be used to secure the upper magnet within the upper slider 1530 without departing from the scope of these disclosures.

[0079] Additionally, the slider mechanism 1502 may include a lower slider 1536 configured to be positioned adjacent to the bottom surface 1538 of the intermediate wall 1518 (shown in FIG. 17). Therefore, FIG. 17 depicts the bottom surface 1538 of the intermediate wall 1518. The lower slider 1536 may include a lower slider magnet encapsulated therein. In one example, the lower slider magnet may be encapsulated within a cavity in the lower slider and may be overmolded using a polymer-overmolded plug element. Additionally, the slider mechanism 1502 may include a lower washer 1544 configured to extend around the periphery of the lower slider 1536. Figure 18A The lower slider 1536 is described in more detail with reference to Figure 18B. In one example, the magnetic attraction between the upper and lower slider magnets across the intermediate wall 1518 magnetically connects the upper slider 1530 to the lower slider 1536. Therefore, manually actuating the upper slider 1530 on the top surface 1520 of the intermediate wall 1518 causes both the upper slider 1530 and the lower slider 1536 to slide.

[0080] Figure 17 depicts a bottom view of the cover assembly 1500 according to one or more aspects described herein. Figure 17 depicts the bottom surface 1538 of the intermediate wall 1518. Thus, as shown, the bottom surface 1538 defines a first inclined feature 1552 on a first side of the second opening 1524. The first inclined feature 1552 has a ridge surface or point 1554 spaced apart between two groove-like recesses 1556a and 1556b. Similarly, a second inclined feature 1558 is positioned on a second side of the second opening 1524. The second inclined feature 1558 includes a ridge surface or point 1560 spaced apart between two groove-like recesses 1562a and 1562b.

[0081] Additionally, the cover assembly 1500 includes a recess 1561 extending into the inner surface 1563 of a sidewall that extends below the bottom surface 1538 of the intermediate wall 1518. Therefore, when the slider mechanism 1502 is in the closed position shown in FIG. 15, the recess 1561 accommodates a portion of the lower slider 1536.

[0082] The second opening 1524 may include engagement portions 1548 extending from the intermediate wall 1518 into the second opening 1524. When the slider mechanism 1502 is in the closed position shown in FIG. 15, these engagement portions 1548 are configured to be received in a channel 1550 (see FIG. 18B) that extends along a portion of the curved walls 1646a and 1646b of the lower slider 1536. Thus, the engagement portions 1548 are configured to provide an interference fit to prevent the slider mechanism 1502 from being unintentionally moved and thus unintentionally unlocking the first opening 1504. In one example, the slider mechanism 1502 may be configured to lock in both the open and / or closed configurations. It is further contemplated that, in addition to the engagement portions 1548, a locking mechanism may be used to further prevent the slider mechanism 1502 from being unintentionally moved.

[0083] Figures 18A and 18B depict isometric views of a sliding member 1536 according to one or more aspects described herein. The sliding member 1536 includes an inner surface 1564 configured to be positioned adjacent to the bottom surface 1538 of the intermediate wall 1518. The inner surface 1564 includes a sliding member ramp 1566. The sliding member ramp 1566 is configured to be received in one of the groove-like recesses of each of the first and second inclined features 1552 and 1558. Accordingly, when the slider mechanism 1502 slides between the open and closed configurations, the sliding member ramp 1566 is configured to slide on the first and second inclined features 1552 and 1558. When the slider mechanism 1502 translates between the open and closed configurations, the sliding member ramp 1566 will abut ridge surfaces 1554 and 1560. Furthermore, because the ridge surfaces 1554 and 1560 are raised relative to the groove-like recesses on either side of the ridge surfaces 1554 and 1560, this further separates the upper slider 1530 and the lower slider 1536 from each other. Accordingly, since the magnetic force between the upper and lower slider magnets is inversely proportional to the square of the distance between them, the magnetic attraction will decrease when the lower slider slope 1566 abuts against the ridge surfaces 1554 and 1560. In one example, this decrease in magnetic force will allow the slider mechanism 1502 to move smoothly between the open and closed positions. Furthermore, when the lower slider slope 1566 is positioned within the groove-like recesses of the first inclined feature 1552 and the second inclined feature 1558, the relatively short distance between the upper and lower slider magnets will create a relatively strong magnetic attraction that secures the slider mechanism 1502 in the open or closed configuration.

[0084] The lower slider 1536 includes curved walls 1646a and 1646b extending from the inner surface 1564 to the tabs / tab lugs 1568a and 1568b. The tab lugs 1568a and 1568b are configured to extend through the second opening 1524. The lower slider 1536 further includes a channel 1570 configured to receive a portion of the lower washer 1544. Additionally, the lower slider 1536 includes lower ventilation channels 1571a and 1571b. Thus, when the slider mechanism 1502 is in the open configuration, one or more of the lower ventilation channels 1571a or 1571b can provide a passage for air to pass from the external environment through the slider mechanism 1502 and into the internal cavity of the container 1505. This airflow path can reduce or prevent blockage when liquid is poured from the first opening 1504. Furthermore, the airflow path can be configured to reduce the pressure difference between the internal cavity of container 1505 and the external environment. Accordingly, as gas / air is allowed to escape through slider mechanism 1502 to the external environment surrounding container 1505, the increased pressure within the internal cavity of container 1505 can be partially or completely released.

[0085] Additionally, the lower slider 1536 includes a knob vent 1802 extending from the sealing surface 1650 to the lower surface 1804 of the knob 1574. The knob vent is configured to allow air to pass between the internal cavity of the container 1505 and the external environment surrounding the container 1505. In one example, air can flow through the knob vent 1802, through the second opening 1524, and out to the external environment. In one example, when the lower slider 1536 and the upper slider 1530 are positioned from the closed position shown in FIG. 15 to the open position schematically shown in FIG. 22, the lower slider 1536 is spaced apart from the upper slider 1530. This spacing releases the radial ridge 1664 from the sealing surface 1640 and allows air to flow through the knob vent 1802 between the internal cavity of the container 1505 and the external environment. When liquid is poured from the first opening 1504, the knob vent 1802 can reduce or prevent blockage caused by the relative pressure difference between the internal cavity of the container and the external environment.

[0086] In one example, the curved walls 1646a and 1656b may be separated by gaps 1648a and 1648b. These gaps 1648a and 1648b allow air to escape when a portion of the upper slider 1530 contacts the sealing surface 1650 of the lower slider 1536. In one example, the sealing surface 1650 may have a smooth surface texture to enhance the seal between the upper slider 1530 and the lower slider 1536. In one example, the sealing surface 1650 may include a polished surface finish and may be an SPI-A2 finish.

[0087] In one example, the separation distance between the lower surfaces 1652a or 1652b of the tabs 1568a and 1568b and the inner surface 1564 prevents the lower slider 1536 from being inserted into the wrong side of the slider mechanism 1502. Specifically, the spacing between the lower surfaces 1652a or 1652b of the tabs 1568a and 1568b and the inner surface 1564 can be less than the wall thickness between the top surface 1520 and the bottom surface 1538. This geometry prevents the lower slider 1536 from being inserted into the second opening 1524 such that the inner surface 1564 contacts the recess 1522. Figure 19 depicts a configuration in which the lower slider 1536 is positioned on the wrong top surface 1520 but cannot be fully inserted into the recess 1522.

[0088] Figure 18B depicts an isometric view of the outer surface 1572 of the lower slider 1536. In one example, a knob 1574 extends from the outer surface 1572. The knob 1574 is configured to be gripped by a user to mount the slider mechanism 1502 in the cover assembly 1500. The knob 1574 may include a gripping surface finish. In one example, the knob 1574, or a portion thereof, may be formed of a first material, while the remainder of the lower slider 1536 may be formed of a different second material. In one example, the knob 1574 may have a rubber-coated outer surface. The lower slider 1536 encapsulates a lower slider magnet, similar to the lower magnet 142. In one example, the lower slider magnet of the lower slider 1536 is encapsulated within the knob 1574.

[0089] Figure 20 depicts a view of the inner side 1582 of the upper slider 1530. The upper slider 1530 includes upper ventilation channels 1584a and 1584b. When the upper ventilation channels 1584a and 1584b allow air to enter the slider mechanism 1502 from the external environment, a vent is formed between the external environment and the internal cavity of the container 1505. Upper slider recesses 1586a and 1586b are configured to receive portions of the tab lugs 1568a and 1568b of the lower slider 1536. A cylindrical gasket 1660 extends from the upper slider 1530 and is configured to be received between the curved walls 1646a and 1646b of the lower slider 1536. The cylindrical gasket 1660 includes a lower surface 1662 having a radial ridge 1664. The lower surface 1662 and radial ridge 1664 are configured to abut a sealing surface 1650. In one example, when the slider mechanism 1502 is in a closed and / or open configuration, with the upper slider 1530 magnetically coupled to the lower slider 1536, the radial ridge 1664 forms a seal with the sealing surface 1640. The radial ridge 1664 may be formed of a rubber material. In one example, the radial ridge 1664 may be formed of thermoplastic vulcanized rubber (TPV). The upper slider 1530 encapsulates an upper slider magnet. In one example, the upper slider magnet may be similar to the upper magnet 132. In one example, the upper slider magnet is encapsulated within a cylindrical gasket 1660.

[0090] In one embodiment, the slider mechanism may include an upper slider 1530 and a lower slider 1536, such that movement of the upper slider 1530 causes the lower slider 1536 to move in the same direction. This synchronized movement may be caused by a cylindrical pad 1660 of the upper slider 1530 abutting one or more surfaces of the curved walls 1646a and 1646b of the lower slider 1536. In one example, the synchronized movement of the upper slider 1530 and the lower slider 1536 may not utilize a magnet to push the upper slider 1530 towards the lower slider 1536. In this example, the upper slider 1530 and / or the lower slider 1536 may be achieved without a magnetic element, such that there is no magnetic attraction between the upper slider 1530 and the lower slider 1536.

[0091] Figures 21A and 21B depict isometric and front views of the lower washer 1544 according to one or more aspects described herein. Thus, when the slider mechanism 1502 is in the closed configuration shown in Figure 15, the lower washer 1544 is configured to seal the first opening 1504. Additionally, the lower washer 1544 is configured to seal the second opening 1524. In one example, the inner surface 1588 of the lower washer 1544 is configured to be positioned above the outer surface 1572 of the lower slider 1536. The opening 1590 in the lower washer 1544 is configured to allow the knob 1574 of the lower slider 1536 to extend through. In one example, the lower washer 1544 may be made of silicone. However, other or alternative polymeric materials may be used without departing from the scope of this disclosure. In one example, the lower washer 1544 may be integrally formed with the bottom slider 1536. Therefore, the lower washer 1544 can be formed from the same or different material as the bottom slider 1536 using a single-stage or multi-stage (single-shot or multi-shot) molding process.

[0092] In one example, and as shown in the front view of Figure 21B, the lower washer 1544 may have a lip 1692 that extends further from the inner surface 1588 than the similar spring feature 192 of the lower washer 144. Therefore, when the lower washer 1544 is positioned on the bottom surface 1538 of the cover 1501, the lip 1692 can provide an enhanced seal.

[0093] Figure 22 schematically depicts the cover assembly 1500 in an open configuration. In one example, the rear wall 1690 of the recess 1522 is configured to abut the upper slider 1530 when positioned in the open configuration of Figure 22. Thus, when in the open configuration shown, the lower slider ramp 1566 can be held on the ridge surfaces 1554 (and 1560). In this configuration, the lower gasket 1544 can be spaced apart from the bottom surface 1538, allowing air to flow between the internal cavities of the container 1505, through the cover assembly 1500, and out to the external environment, thereby preventing or limiting blockage during pouring.

[0094] Figures 23 through 40 depict another embodiment of a lid assembly 2000 configured to be removably coupled to container 1505 according to one or more aspects described herein. Lid assembly 2000 may be interchanged with lid assembly 1500 or lid assembly 100, such that lid assembly 2000 can be removably coupled to container 105, container 1505, or other similar containers. Lid assembly 2000 may include multiple elements similar to those of lid assemblies 100 and 1500, such that if those features are marked with the first two digits “20” and the last two digits are the same as those described with respect to lid assemblies 100 and 1500, the reference numerals used to describe the features of lid assembly 2000 may include elements with similar features described with respect to lid assemblies 100 and 1500. For example, slider mechanism 1502 described with respect to lid assembly 1500 may be similar to slider mechanism 2002, since both elements are indicated by a designation ending in “02”. Furthermore, the features of cover assembly 2000 may include features marked with the first two digits "21" or "22" and the last two digits being the same as those described for cover assembly 1500, which respectively has the first two digits "16" or "18". Because these features are similar, these features of cover assembly 2000 may be described in less detail or not at all. Additional, alternative, or distinguishing features of the elements of cover assembly 2000 relative to the elements of cover assemblies 100 and 1500 may be noted in the foregoing description.

[0095] Figures 23 to 34 depict a cap assembly 2000. The cap assembly 2000 generally includes a slider mechanism 2002 configured to move between a closed position (shown in Figure 23) and an open position to selectively close or open a first opening 2004 through which liquid stored in the container is configured to flow. Additionally, the cap assembly 2000 may include a sidewall 2006 that may define a recess 2008 for placing a gasket 2010. Thus, the gasket 2010 can provide a seal between the cap assembly 2000 and the container. However, other sealing methods for sealing the cap assembly 2000 to the container are also contemplated. The cap assembly 2000 may also include an edge 2012 for engaging the opening of the container. The edge 2012 may include a top wall 2014 and a gripping element 2116 extending from the top wall 2014 to assist a user in removing the cap assembly 2000 from the container.

[0096] The lid assembly 2000 may include a lid 2001 having a central wall 2018 extending below an edge 2012. The top surface 2020 of the central wall 2018 may define a recess 2022 for receiving a slider mechanism 2002. In one example, the recess 2022 may define a guide channel as the slider mechanism 2002 moves between a closed position and an open position as shown in FIG. 23. A first opening 2004 for drinking or pouring liquid from the container may also be formed in the recess 2022. The recess 2022 may also include a second opening 2024.

[0097] The slider mechanism 2002 may include an upper slider 2030 configured to be positioned within a recess 2022 on the top surface 2020 of the intermediate wall 2018. The upper slider 2030 may include an upper magnet encapsulated therein. In one example, the upper magnet may be encapsulated within a cavity in the upper slider 2030 and may be overmolded with a polymer-overmolded plug element. Other or alternative encapsulation methods may be used to secure the upper magnet within the upper slider 2030 without departing from the scope of these disclosures.

[0098] Additionally, the slider mechanism 2002 may include a lower slider 2036 configured to be positioned adjacent to the bottom surface 2038 of the intermediate wall 2018 (shown in FIG. 32). Therefore, FIG. 36 depicts the bottom surface 2038 of the intermediate wall 2018. The lower slider 2036 may include a lower slider magnet encapsulated therein. In one example, the lower slider magnet may be encapsulated within a cavity in the lower slider 2036 and may be overmolded using a polymer-overmolded plug element. Additionally, the slider mechanism 2002 may include a lower washer 2044 configured to extend around the periphery of the lower slider 2036. The lower slider 2036 is described in further detail with reference to FIGS. 38 through 40. In one example, magnetic attraction between the upper and lower slider magnets magnetically couples the upper slider 2030 to the lower slider 2036 on the intermediate wall 2018. Therefore, manually actuating the upper sliding member 2030 on the top surface 2020 of the intermediate wall 2018 causes both the upper sliding member 2030 and the lower sliding member 2036 to slide.

[0099] As shown in Figure 35, the recess 2022 may include a tapered surface 2025 between the first opening 2004 and the second opening 2024. The tapered surface 2025 provides a first depth of the recess 2022 near and / or adjacent to the first opening 2004, which may be greater than a second depth adjacent to the second opening 2024. The tapered surface 2025 may extend onto either side or both sides of the first opening 2004. Additionally, the tapered surface 2025 may extend onto either side or both sides of a portion of the second opening 2024. The tapered surface 2025 allows the front portion 2031 of the upper slider 2030 to tilt downwards into the region above the tapered surface 2025 to initiate actuation of the slider mechanism 2002 from a closed position to an open position, as will be discussed in more detail below.

[0100] The upper surface 2023 of the recess 2022 may also include a pair of engaging members 2170. Each engaging member 2170 may include a first inclined surface 2172 and a second inclined surface 2174 arranged adjacent to each other. The pair of engaging members 2170 may be spaced apart from each other and also arranged substantially parallel to each other. Furthermore, a majority of each engaging member 2170 may be positioned behind the second opening 2024. In some examples, the entirety of each engaging member 2170 may be positioned behind the second opening 2024. Each engaging member 2170 may be individually received within a corresponding channel 2180 arranged along the lower surface of the upper slider 2030. Each channel 2180 of the lower slider may include a rear channel engaging member 2182. When the slider mechanism 2002 is in the closed position, each rear channel engagement member 2182 is positioned in front of the engagement member 2170 in the recess 2022, and when the slider mechanism 2002 is in the open position, each rear channel engagement member 2182 is positioned behind the engagement member 2170. The interaction between the engagement members 2170 and their respective receiving channels 2180 can help guide the slider mechanism 2002 to move forward and backward. Furthermore, the engagement members 2170 and the rear channel engagement members 2182 can contact each other and act as stops to limit or restrain the movement of the slider mechanism 2002 to prevent accidental opening of the cover assembly 2000. Although the illustrated cover assembly 2000 depicts two engagement members 2170, the cover 2001 may include a single engagement member 2170, which is substantially longitudinally centered within the recess 2022 and positioned behind the second opening 2024. The single engaging member 2170 can be accommodated in a centrally located channel 2180 extending along the lower surface of the upper slider 2030.

[0101] Furthermore, for each joining member 2170, the first inclined surface 2172 may be arranged such that a first angle between the upper surface 2023 and the first inclined surface 2172 (which may be defined as the angle between the upper surface 2023 and the first inclined surface 2172 in the counterclockwise direction) may be greater than a second angle between the upper surface 2023 and the second inclined surface 2174 (which may be defined as the angle between the upper surface 2023 and the second inclined surface 2174 in the clockwise direction). Similarly, each rear channel joining member 2182 may have a first inclined surface 2184 and a second inclined surface 2186 arranged adjacent to each other. The first inclined surface 2184 may be arranged such that a first angle between the bottom channel surface 2185 and the first inclined surface 2184 (when the upper slider 2030 has an upward-facing bottom channel surface 2185, this first angle may be defined as the angle between the bottom channel surface 2185 and the first inclined surface 2184 in the counterclockwise direction) may be smaller than a second angle between the bottom channel surface 2185 and the second inclined surface 2186 (when the upper slider 2030 has an upward-facing bottom channel surface 2185, this second angle may be defined as the angle between the bottom channel surface 2185 and the second inclined surface 2186 in the clockwise direction). When the slider mechanism 2002 is in the closed position, each second inclined surface 2174 of each engaging member 2170 may face the first inclined surface 2184 of each rear channel engaging member 2182. When the slider mechanism 2002 is in the open position, each first inclined surface 2172 of each engagement member 2170 can face the second inclined surface 2186 of the rear channel engagement member 2182.

[0102] Each channel 2180 may extend through the front surface 2190 of the upper slider 2030 and may also extend through the rear surface 2192 of the upper slider 2030. Each channel 2180 may be intermittent; that is, it does not extend continuously from the front surface 2190 to the rear surface 2192. Each channel 2180 may be arranged on either side of the cylindrical gasket 2160 or may be interrupted by the cylindrical gasket 2160. In an alternative example, each channel 2180 may be continuous from the front surface 2190 to the rear surface 2192. Each channel 2180 may be spaced apart from each other and substantially parallel. Furthermore, each channel 2180 may include a front channel engagement member 2196. Each front channel engagement member 2196 may have the same geometry and shape as each rear channel engagement member 2182. Each front channel engagement member 2196 can be a mirror image of the rear channel engagement member 2182 relative to a plane that extends perpendicularly to the channel 2180 and passes through the center of the upper slider 2030. Because the channel engagement members 2182, 2196 are positioned as mirror images, the upper slider 2030 can be assembled in multiple directions.

[0103] In addition to the interaction between channel 2180 and engaging member 2170, slider mechanism 2002 can also interact with cover 2001 in a similar manner to slider mechanism 1502 and cover 1501. For example, as shown in FIG36, cover 2001 may have a bottom surface 2038 of intermediate wall 2018, which includes a first inclined feature 2052 on a first side of second opening 2024 and a second inclined feature 2058 disposed on the opposite side of second opening 2024. The first inclined feature 2052 has a ridge surface or point 2054 spaced apart between two groove-like recesses 2056a and 2056b. Similarly, the second inclined feature 2058 may include a ridge surface or point 2060 spaced apart between two groove-like recesses 2062a and 2062b.

[0104] Figures 33A to 33F depict the process by which a user moves the slider mechanism 2002 from the closed position shown in Figure 33A to the fully open position shown in Figure 33F. As shown in Figure 33B, the first step of this process depicts the slider mechanism 2002 moving slightly backward from the closed position when the user begins to apply a backward force, but the engaging member 2170 prevents further movement. Next, in Figure 33C, the user can press down on the front 2031 of the upper slider 2030, which causes the rear 2033 to move upward. As the rear 2033 moves upward, any gas or fluid that may be under pressure between the upper slider 2030, the lower slider 2036, and the container is released outward from the rear of the upper slider 2030, away from the position where the user can place his or her mouth to drink from the cap 2001. For example, when the upper slider 2030 is tilted, the sealing surface 2150 of the lower slider can be released from the radial ridge 2164 of the lower surface 2162 of the upper slider 2030, causing any pressurized gas or liquid in the container to be released. Next, as shown in Figures 33D and 33E, when the user applies a rearward force to the slider mechanism 2002, the first inclined surface 2184 of the rear channel engagement member 2182 can slide along the second inclined surface 2174 of the engagement member 2170, thereby allowing the rear channel engagement member 2182 to slide over and then past the engagement member 2170. Simultaneously, the lower ramp slider 2066 of the lower slider 2036 begins to move from the first grooved recess 2056a to the second grooved recess 2056b. In the final step of the opening process shown in Figure 33F, the user can continue to apply a backward force until the lower ramp slider 2066 engages the second grooved recess 2056b and / or the rear surface 2192 of the upper slider 2030 contacts the stop surface of the recess 2022. The cover assembly 2000 is now in the open position and ready to allow fluid to flow through the opening 2004. To move the slider mechanism 2002 back to the closed position, the user can apply a forward force to the upper slider 2030. The second inclined surface 2184 slides upward and over the first inclined surface 2172, as shown in Figure 34. The upper slider 2030 is then moved to cover the first opening 2004 to move the slider mechanism 2002 into the closed position, as shown in Figure 33A.

[0105] Figure 37 depicts a view of the upper slider 2030. The upper slider 2030 may include upper ventilation channels 2084a and 2084b. When the upper ventilation channels 2084a and 2084b allow air to enter the slider mechanism 2002 from the external environment, a vent is formed between the external environment and the internal cavity of the container. Upper slider recesses 2086a and 2086b are configured to receive portions of tab lugs 2068a and 2068b of the lower slider 2036. A cylindrical gasket 2160 extends from the upper slider 2030 and is configured to be received between the curved walls 2046a and 2046b of the lower slider 2036. The cylindrical gasket 2160 includes a lower surface 2162 having a radial ridge 2164. The lower surface 2162 and radial ridge 2164 are configured to form a sealing surface 2150 abutting the lower slider 2036. In one example, when the slider mechanism 2002 is in a closed and / or open configuration, the radial ridge 2164 forms a seal with the sealing surface 2150 when the upper slider 2030 is magnetically coupled to the lower slider 2036. The radial ridge 2164 may be formed of a compliant material such as a rubber-based material. In one example, the radial ridge 2164 may be formed of a thermoplastic vulcanizate (TPV) material. The upper slider 2030 may encapsulate an upper slider magnet. In one example, the upper slider magnet may be similar to the upper magnet 132. In one example, the upper slider magnet is encapsulated within a cylindrical gasket 2160.

[0106] Figures 38 to 40 depict a lower slider 2036. The lower slider 2036 may include an inner surface 2064 configured to be positioned adjacent to the bottom surface 2038 of the intermediate wall 2018. The lower slider 2036 may have features similar to those of the lower slider 1536, such as an interactive lower ramp slider 2066 configured to be received in one of the groove-like recesses of each of the first inclined feature 2052 and the second inclined feature 2058. Accordingly, when the slider mechanism 2002 slides between the open and closed configurations, the lower ramp slider 2066 is configured to slide on the first inclined feature 2052 and the second inclined feature 2058. Furthermore, the lower slider 2036 may also include curved walls 2146a and 2146b extending from the inner surface 2064 to the tabs / tab lugs 2068a and 2068b. Lugs 2068a and 2068b are configured to extend through the second opening 2024. The lower slider 2036 further includes a channel 2070 configured to receive a portion of the lower washer 2044. Additionally, the lower slider 2036 may include lower ventilation channels 2071a and 2071b to provide a passage for air to flow from the external environment through the slider mechanism 2002 and into the internal cavity of the container. This airflow path can reduce or prevent blockage when liquid is poured from the first opening 2004. Furthermore, the airflow path can be configured to reduce the pressure difference between the internal cavity of the container and the external environment. In this way, the increased pressure within the internal cavity of the container can be partially or completely released as gas / air is allowed to escape through the slider mechanism 2002 to the external environment surrounding the container. This ventilation can also occur as described above when the slider mechanism 2002 tilts as it moves from a closed position to an open position.

[0107] Additionally, the lower slider 2036 includes a knob vent 2202 extending from the sealing surface 2150 to the lower surface 2204 of the knob 2074. The knob vent 2202 is configured to allow air to pass between the internal cavity of the container and the external environment surrounding the container. In one example, air can pass through the knob vent 2202, through the second opening 2024, and out to the external environment. In one example, when the lower slider 2036 and the upper slider 2030 move from the closed position shown in FIG33A to the open position schematically depicted in FIG33F, the lower slider 2036 is unsealed from the sealing surface 2150 and the radial ridge 2164, allowing air to flow through the knob vent 2202 between the internal cavity of the container and the external environment. When liquid is poured from the first opening 2004, the knob vent 2202 can reduce or prevent blockage due to the relative pressure difference between the internal cavity of the container and the external environment.

[0108] As shown in Figure 40, the knob vent 2202 may have a knob vent 2202 extending from the sealing surface 2150 to the lower surface 2204. The knob vent 2202 may include a first vent 2206 at the lower surface 2204, a second vent 2208 at the sealing surface 2150, and a venting inner surface 2210 between the first vent 2206 and the second vent 2208. The knob vent 2202 may have a first circular inlet portion 2212 (i.e., fillet radius) transitioning from the lower surface 2204 to the venting inner surface 2210. Similarly, the knob vent 2202 may have a second circular inlet portion 2214 (i.e., fillet radius) transitioning from the sealing surface 2150 to the venting inner surface 2210 at the second vent 2208. By adding circular inlets 2212 and 2214, pressure buildup between the upper slider 2030 and the lower slider 2036 can be reduced. In some examples, the first vent 2206 may have a first diameter, while the second vent 2208 may have a second diameter, wherein the first diameter may be smaller than the second diameter. Furthermore, the ratio of the first diameter to the second diameter may be approximately 0.8:1.0 or in the range of 0.7:1.0 to 0.9:1.0. Additionally, the vent inner surface 2210 may include a conical or tapered surface that expands as it moves from the first circular inlet 2212 to the second circular inlet 2214, or the vent inner surface 2210 may have a generally cylindrical shape. A third diameter (i.e., between the first and second diameters) measured at the minimum region along the vent inner surface 2210 may be smaller than the first diameter. The third diameter may be in the range of 1.0 to 1.25 mm. The first diameter can be in the range of 4 mm to 5 mm, or in the range of 3 mm to 6 mm. Another way to represent the size of the third diameter is as a ratio of the third diameter to the first diameter. For example, the ratio of the third diameter to the first diameter can be approximately 0.27:1.0, in the range of 0.2:1.0 to 0.3:1.0, or in the range of 0.2:1 to 0.5:1.0. In some examples, the first circular portion can have a radius of approximately 2.9 mm or in the range of 2.5 to 3.5 mm, while the second circular portion can have a radius of approximately 3.8 mm or in the range of 3.5 to 4.5 mm. The radius of the first circular inlet 2212 can be smaller than the radius of the second circular inlet 2214. Another way to express the size of the circular inlets 2212 and 2214 is as a ratio of the radius of the first circular inlet 2212 to the radius of the second circular inlet 2214.For example, the ratio of the radius of the first circular inlet 2212 to the radius of the second circular inlet 2214 can be approximately 0.76:1, or it can be in the range of 0.7:1 to 0.8:1. The geometry of the vent 2202 allows air to be released from the container at a certain rate to prevent any adverse pressure buildup between the contents of the container and the slider mechanism 2002.

[0109] In one embodiment, the cap assembly may include an edge for engaging a container opening, wherein the edge defines a top wall. Additionally, the cap assembly may include sidewalls defining recesses for placing an upper gasket. An intermediate wall may extend below the edge, and the top surface of the intermediate wall defines a recess. The recess may have a first opening, a second opening, and a vent. The bottom surface of the intermediate wall may define a first inclined feature having ridge surfaces spaced apart between two grooved recesses. The first inclined feature may be positioned on a first side of the second opening, and a second inclined feature may have ridge surfaces spaced apart between two grooved recesses, wherein the second inclined feature is positioned on a second side of the second opening. Furthermore, the cap assembly may include a slider mechanism configured to be manually slidable to selectively provide a closed position by covering both the first and second openings and to selectively provide an open position by covering only the second opening.

[0110] In another example, when the slider mechanism slides between the open and closed positions, the lower sliding slope of the cover assembly is configured to slide above the ridge surfaces of the first and second inclined features.

[0115] By applying a manual force to overcome the magnetic force between the upper and lower sliding magnets, the upper sliding member of the cover assembly can be manually removed from the cover assembly.

[0116] The tabs of the cover assembly can be configured to engage with the side of the second opening to prevent the lower slider from separating from the cover assembly when the upper slider is removed from the cover assembly.

[0117] The sliding member may further include finger-like protrusions extending from the outer surface.

[0141] In another example, the spacing between the inner surface of the lower slider and the first and second protruding lugs prevents the first and second protruding lugs from being inserted into the second opening when the lower slider is incorrectly positioned on the top surface of the intermediate wall.

[0142] In one example, as the lower slider slope slides from the first and second grooved recesses to the first and second ridge surfaces, the lower slider moves away from the upper slider.
