DETAILED DESCRIPTION OF THE INVENTION

[0008] In the following various examples and descriptions of the components of the present disclosure, reference is made to the accompanying drawings which form a part thereof and which illustrate various exemplary structures and environments in which aspects of the present disclosure may be implemented. It is to be understood that other structures and environments may be utilized and that structural and functional changes may be made from the specifically described structures and methods without departing from the scope of the present disclosure.

[0009] Also, terms such as "front side", "back side", "top", "base", "bottom", "side", "front", "rear" may be used in this specification to describe various exemplary features and elements, and these terms are used in this specification for convenience based on, for example, the exemplary orientation shown in the figures and / or the orientation in typical use. Nothing in this specification should be construed as requiring a particular three-dimensional or spatial orientation of the structure in order to be included within the scope of the claims.

[0010] FIG. 1 shows an isometric view of a lid assembly 100 removably coupled to a container 105 according to one or more aspects described in this specification. The container 105 is an example of a container that can be configured such that the lid assembly 100 is removably coupled thereto. Thus, the container 105 can be configured to store a volume of liquid, and the lid assembly 100 can be configured to seal an opening of the container 105.

[0011] FIGS. 2A and 2B show isometric views of the lid assembly 100 in a closed configuration and an open configuration, respectively. The lid assembly 100 generally includes a slider mechanism 102 configured to move between a closed position (shown in FIG. 2A) and an open position (shown in FIG. 2B) to selectively close or open a first opening 104 configured such that liquid stored within the container 105 can flow therethrough. Further details regarding the slider mechanism 102 are considered in relation to the preceding drawings. The lid assembly 100 may additionally include a sidewall 106, which can define a groove 108 for placement of a gasket 110. Thus, the gasket 110 can provide a seal between the lid assembly 100 and the container 105. However, other sealing methods for sealing the lid assembly 100 to the container 105 are also contemplated. The lid assembly 100 may also include an edge 112 for engaging an opening of the container 105. The edge 112 may also include a top wall 114 and a gripping element 116 and / or an optional lid tab (not shown) extending from the top wall 114 to assist a user in removing the lid assembly 100 from the container 105.

[0012] The lid assembly 100 may also include an intermediate wall 118 that extends below the edge 112. The upper surface 120 of the intermediate wall 118 can define a recess 122 for receiving the slider mechanism 102. In one embodiment, as the slider mechanism 102 moves between the closed position shown in FIG. 2A and the open position shown in FIG. 2B, the recess 122 can define a guide channel. As shown in FIG. 2B, a first opening 104 for drinking or pouring liquid from the container can also be formed within the recess 122. The recess 122 can also include a second opening 124 that is described in more detail with respect to FIG. 5A. A detent 126 can extend from the upper surface 120 of the intermediate wall 118 into the recess 122. This detent 126 is configured to abut the slider mechanism 102 when in the open position shown in FIG. 2B to prevent liquid from being compressed between the slider mechanism 102 and the end wall 128 of the recess 122 (otherwise, as a result of the user drinking or pouring from the first opening 104, it could cause splashing of the liquid that could accumulate within the recess 122).

[0013] FIG. 3 schematically shows an exploded isometric view of the lid assembly 100 according to one or more aspects described herein. In particular, FIG. 3 schematically shows the plurality of elements that make up the slider mechanism 102, as considered with respect to FIGS. 2A and 2B. Thus, the slider mechanism 102 can include an upper thread 130 that is configured to be positioned within the recess 122 at the upper surface 120 of the intermediate wall 118. The upper thread 130 can include an upper magnet 132 that is sealed therein. In one embodiment, the upper magnet 132 can be sealed within a cavity in the upper thread 130 and overmolded with a polymer overmold plug element 134. Without departing from the scope of these disclosures, additional and alternative sealing methods can be used to secure the upper magnet 132 within the upper thread 130. Additionally, the upper thread magnet 132 can be formed of any suitable ferromagnetic material, or a magnetic material otherwise. The upper thread 130 is considered in more detail with respect to FIGS. 7A and 7B.

[0014] The slider mechanism 102 may additionally include a lower thread 136 configured to be positioned adjacent to the bottom surface 138 of the intermediate wall 118 (shown in FIG. 5B). The lower thread 136 may include a lower thread magnet 140 sealed therein. In one embodiment, the lower thread magnet 140 may be sealed within a cavity in the lower thread 136 and overmolded with a polymer overmold plug element 142. Additionally, the slider mechanism 102 may include a lower gasket 144 configured to extend around the outer periphery of the lower thread 136. The lower thread 136 is described in further detail with respect to FIGS. 6A and 6B.

[0015] In one embodiment, the magnetic attraction between the upper thread magnet 132 and the lower thread magnet 140 magnetically couples the upper thread 130 to the lower thread 136 across the intermediate wall 118. Thus, manual operation of the upper thread 130 above the upper surface 6 of the intermediate wall 118 results in a sliding movement of the upper thread 130 and the lower thread 136.

[0016] FIG. 4 schematically shows a cross-sectional view of the lid assembly 100 according to one or more aspects described herein. As shown, the slider mechanism 102 is in a closed configuration such that a first opening 104 is sealed by the slider mechanism 102. In one embodiment, the lower thread magnet 140 may have a cylindrical geometry with a hollow center. Thus, the lower thread magnet 140 may be described as a ring magnet extending around the central tube 146 through the overmolded plug element 142 and the lower thread 136, as would otherwise be the case. In another embodiment, the lower thread magnet 140 may have a three-dimensional cylindrical geometry.

[0017] Figures 5A and 5B show isometric views of the lid assembly 100 without the slider mechanism 102. In particular, FIG. 5A shows a view of the upper surface 120 of the intermediate wall 118, and FIG. 5B shows a view of the bottom surface 138 of the intermediate wall 118. As shown, the lid mechanism 100 includes a first opening 104 and a second opening 124. In one embodiment, when the upper thread 130 is magnetically coupled to the lower thread 136, a portion of the slider mechanism 102 is configured to extend through the second opening 124.

[0018] The second opening 124 may include detents 148 that extend from the intermediate wall 118 to the second opening 124. When the slider mechanism 102 is in the closed position shown in FIG. 2A, these detents 148 are configured to be received in channels 150 (see FIG. 6A) that extend along a portion of the central tube 146 of the lower thread 136. Thus, the detents 148 are configured to provide an interference fit to prevent the slider mechanism 102 from being inadvertently moved and thereby inadvertently opening the first opening 104. In one embodiment, the slider mechanism 102 may be configured to lock in the open and / or closed configurations shown in FIGS. 2A and 2B. It is further contemplated that in addition to the detents 148, a locking mechanism may be used to further prevent the slider mechanism 102 from being inadvertently moved.

[0019] FIG. 5B shows the bottom surface 138 of the intermediate wall 118. Thus, as shown, the bottom surface 138 defines a first inclined feature 152 on the first side of the second opening 124. The first inclined feature 152 has a peak surface 154 that is spaced between two valley recesses 156. Similarly, a second inclined feature 158 is positioned on the second side of the second opening 124. The second inclined feature 158 includes a peak surface 160 that is spaced between two valley recesses 162.

[0020] The lid assembly 100 additionally includes a recess pocket 161 that extends to the inner surface 163 of the sidewall that extends below the bottom surface 138 of the intermediate wall 118. Thus, when the slider mechanism 102 is in the closed position shown in FIG. 2A, the recess pocket 161 receives a portion of the lower thread 136. When liquid is being poured from the first opening 104, the lid assembly 100 also includes a recess vent pocket 165 such that the geometry of the recess vent pocket 165 allows air to flow into the container 105.

[0021] Figures 6A and 6B show an isometric view of the lower thread 136 according to one or more aspects described herein. Thus, the lower thread 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 thread ramp 166. The lower thread ramp 166 is configured to be received within one of the valley recesses of each of the first ramp feature 152 and the second ramp feature 158. Thus, when the slider mechanism 102 slides between the open configuration and the closed configuration, the lower thread ramp 166 is configured to slide across the first ramp feature 152 and the second ramp feature 158. When the slider mechanism 102 transitions between the open configuration and the closed configuration, the lower thread ramp 166 will contact the peak surfaces 154 and 160. Further, the peak surfaces 154 and 160 are raised relative to the valley recesses on both sides of the peak surfaces 154 and 160, which will urge the upper thread 130 and the lower thread 136 to be further separated from each other. Thus, since the magnetic force between the upper thread magnet 132 and the lower thread magnet 140 is inversely proportional to the square of the distance therebetween, when the lower thread ramp 166 contacts the peak surfaces 154 and 160, the magnetic attraction force will be reduced. In one embodiment, this reduction in magnetic force will provide for smooth movement of the slider mechanism 102 between the open and closed positions. Further, when the lower thread ramp 166 is positioned within the valley recesses of the first ramp feature 152 and the second ramp feature 158, the relatively shorter distance between the upper thread magnet 132 and the lower thread magnet 140 will result in a relatively stronger magnetic attraction force that helps to secure the slider mechanism 102 in the open or closed configuration.

[0022] Note that the lower thread 136 and the upper thread 130 are symmetric about a vertical axis to enable the slider mechanism to be installed within the lid assembly 100 in any of four different directions. The lower thread 136 additionally includes a central tube 146 extending from the inner surface 164. Further, the central tube 146 includes tab ears 168 configured to extend through the second opening 124. The lower thread 136 further includes a channel 170 configured to receive a portion of the lower gasket 144. Additionally, the lower thread 136 includes lower vent channels 171a and 171b. Thus, when the slider mechanism 102 is in the open configuration, a portion of the lower thread 136 extends over a portion of the recessed vent pocket 165. Further, one of the lower vent channels 171a or 171b is positioned over the recessed vent pocket 165, thereby establishing a channel through which air can pass from the slider mechanism 102 to the interior cavity of the container 105.

[0023] FIG. 6B shows an isometric view of the outer surface 172 of the lower thread 136. In one embodiment, a knob 174 (also referred to as a finger tab 174) extends from the outer surface 172. This knob 174 is configured to be gripped by a user to install the slider mechanism 102 within the lid assembly 100. This installation process is described in more detail with respect to FIG. 12.

[0024] Figures 7A and 7B show an isometric view of the upper thread 130. The upper thread 130 can include two symmetric flanges 176a and 176b, both of which are configured to selectively cover and seal the first opening 104 for pouring liquid from the second opening 124 in the container and the recess 122 (also referred to as the guide channel 122). The tab or handle 178 is configured to be gripped by the user to selectively move the upper thread 130, whereby the slider mechanism 102 is in an open position for removing the cover of the first opening 104 on the lid assembly 100, or a closed position for covering the first opening 104 on the lid assembly 100. The tab or handle 178 may include two inwardly tapered portions 180a and 180b for gripping purposes.

[0025] Figure 7B shows a view of the inside 182 of the upper thread 130. Thus, the upper thread 130 includes upper vent channels 184a and 184b. Thus, when the slider mechanism 102 is in the open configuration, the vent path is partially formed by a portion of the lower thread 136 that extends over a portion of the recess vent pocket 165. Additionally, one of the lower vent channels 171a or 171b is positioned over the recess vent pocket 165, thereby establishing a channel through which air can pass from the slider mechanism 102 to the interior cavity of the container 105. This vent path between the external environment and the interior cavity of the container 105 is completed when the upper vent channels 184a and 184b allow air to pass from the external environment to the slider mechanism 102. The upper thread recesses 186a and 186b are configured to receive a portion of the tab ears 168 of the lower thread 136.

[0026] Figures 8A and 8B show an isometric view and a partial cross-sectional view of the lower gasket 144 according to one or more aspects described herein. Thus, when the slider mechanism 102 is in the closed configuration shown in FIG. 2A, the lower gasket 144 is configured to seal the first opening 104. Additionally, the lower gasket 144 is configured to seal the second opening 124. In one embodiment, the inner surface 188 of the lower gasket 144 is configured to be positioned on the outer surface 172 of the lower thread 136. The opening 190 in the lower gasket 144 is configured to allow the knob 174 of the lower thread 136 to extend therethrough. In one embodiment, the lower gasket 144 may be composed of silicone. However, additional or alternative polymeric materials may be used without departing from the scope of these disclosures.

[0027] The cross-sectional view of FIG. 8B shows the spring feature 192 of the lower gasket 144. Thus, the spring feature 192 allows the seal formed by the gasket 144 to move and remain in contact with the bottom surface 138 of the intermediate wall 118. Thus, when in the open and closed configurations, the relatively high magnetic force biasing the lower thread 136 towards the bottom surface 138 of the intermediate wall 118 compresses the spring characteristic 192 of the lower gasket 144. Further, when the lower thread incline 166 is positioned on the peak surfaces 154 and 160 and the magnetic force is relatively lower and the lower thread 136 is moved away from the bottom surface 138, the spring feature 192 extends outwardly towards the bottom surface 138 and maintains contact with the bottom surface 138 to maintain the seal of the lower gasket 144 at the bottom surface 138.

[0028] Figures 9A and 9B schematically show cross-sectional views of the lid assembly 100 in the closed configuration. As shown, the slider mechanism 102, including the upper thread 130 and the lower thread 136, seals the first opening 104. FIG. 9B shows a more detailed view of a portion of the cross-section of FIG. 9A. Thus, FIG. 9B shows a portion of the lower thread 136 and the lower gasket 144 received in the recessed pocket 161 of the lid assembly 100.

[0029] Figures 10A and 10B schematically show cross-sectional views of the lid assembly 100 in the open configuration. As shown, the first opening 104 is completely covered by a slider mechanism 102 that includes an upper thread 130 and a lower side 136. FIG. 10B schematically shows a more detailed view of a portion of the cross-section of FIG. 10A. In particular, FIG. 10B shows a portion of the lower gasket 144 that has been slid over a portion of the recessed vent pocket 165. The overlap of the portion of the lower gasket 144 over the portion of the recessed vent pocket 165 results in a gap 192 through which air can enter the container 105 when liquid is being poured through the first opening 104.

[0030] Figures 11A and 11B schematically show cross-sectional views of the lid assembly 100 in the partially open configuration. As shown, the first opening 104 is partially covered by a slider mechanism 102 that includes an upper thread 130 and a lower thread 136. FIG. 11B schematically shows a more detailed view of a portion of the cross-section of FIG. 11A. In particular, FIG. 11B shows a separation 196 (or gap 196) between the upper thread 130 and the lower thread 136. This separation 196 results from the lower thread incline 166 that abuts the mountain surfaces 154 and 160 as previously described.

[0031] Figures 12A - 12D show various steps for the disassembly and removal of the slider mechanism 102 from the lid assembly 100. As previously explained, the slider mechanism 102 includes an upper thread 130 and a lower thread 136. Further, the upper thread includes an upper thread magnet 132, and the lower thread 136 includes a lower thread magnet 140 and a lower gasket 144. Figure 12A shows the slider mechanism 102 fully installed and the lid assembly 100 in an open configuration. To remove the slider mechanism, for example, to facilitate cleaning of the lid assembly 100, the upper thread 130 can be manually lifted from the upper surface 120. Figure 12B shows the upper thread 130 after being removed from the upper surface 120. Once the upper thread 130 is removed, the lower thread 136 is no longer held against the bottom surface 138 by magnetic attraction between the upper thread magnet 132 and the lower thread magnet 140. However, when the tab ear 168 extends through the second opening 124 and grips on a portion of the upper surface 120, the tab ear 168 prevents the lower thread 136 from falling into the container 105.

[0032] To remove the lower thread 136 from the lid assembly 100, the lower thread 136 is rotated by 90° so that the tab ear 168 can pass through the second opening 124. Figure 12D shows the upper thread 130 and the lower thread 136 completely removed from the lid assembly 100.

[0033] FIG. 13 schematically shows a cross-sectional view of a portion of the lid assembly 100 coupled to the container 105. In one embodiment, the lid assembly 100 can be releasably sealed to the container 105 by a threaded element on both the side wall 106 of the lid assembly 100 and the side wall 202 of the container 105. Elements 204 and 206 are the threads on the side walls 106 and 202, respectively. Further, it is contemplated that any threaded geometry can be used to secure the lid assembly 100 to the container 105 without departing from the scope of these disclosures. Alternatively, the various lid assembly 100 structures described throughout this disclosure can be implemented without a threaded connection between the lid assembly 100 and the container 105. In one embodiment, the lid assembly 100 can be secured to the container 105, among other things, by interference fit.

[0034] FIGS. 14A - 14E show alternative implementations of a slider mechanism having an alternative disassembly mechanism. Thus, FIG. 14A shows an isometric view of a lid assembly 300 including a slider mechanism 301. The lid assembly 300 can be similar to the lid assembly 100, and the slider mechanism 301 can be similar to the slider mechanism 102. The slider mechanism 301 can include an upper thread 302 similar to the upper thread 130 and a lower thread 306 similar to the lower thread 136. To disassemble the slider mechanism, the upper thread 302 can be manually removed from the lid assembly 300. Similar to the lower thread 136, the lower thread 306 can include a tab ear 308 to prevent the lower thread 306 from falling into the container when the upper thread 302 is removed. However, to remove the lower thread 306 from the lid assembly 300, the lower thread 306 is slid to the position shown in FIG. 14C so that the geometry of the tab ear 308 aligns with the geometry of the opening 309 in the intermediate wall 310 of the lid assembly 300. When positioned in the configuration shown in FIG. 14C, the lower thread 306 can pass through the opening 309 as shown in FIG. 14D. FIG. 14E shows the upper thread 302 and the lower thread 306 completely removed from the lid assembly 300.

[0035] FIG. 15 shows an implementation of a lid assembly 1500 configured to removably couple to a container 1505 according to one or more aspects described herein. The lid assembly 1500 and the container 1505 may be interchangeable with the lid assembly 100 and the container 105, such that the lid assembly 1500 may be removably coupled to the container 105 and the lid assembly 100 may be removably coupled to the container 1505. The lid assembly 1500 may include a plurality of elements similar to the lid assembly 100, such that, if those features are labeled with the first two digits being "15" and the last two digits being the same as those described in relation to their lid assembly 100, the reference numbers used to describe the features of the lid assembly 1500 may include elements of similar features described in relation to the lid assembly 100. For example, the slider mechanism 102 described in relation to the lid assembly 100 may be similar to the slider mechanism 1502, as both elements are denoted by labels ending with "02". Additional, alternative, or differentiating features of the elements of the lid assembly 1500 with respect to the elements of the lid assembly 100 may be pointed out in the ongoing description.

[0036] FIG. 16 schematically shows an exploded view of a plurality of elements of the lid assembly 1500 according to one or more aspects described herein. The lid assembly 1500 generally includes a slider mechanism 1502 configured to move between a closed position and an open position (shown in FIG. 15) to selectively close or open a first opening 1504 configured to allow liquid stored within the container 1505 to flow. The lid assembly 1500 may additionally include a sidewall 1506, which can define a groove 1508 for placement of the gasket 1510. Thus, the gasket 1510 can provide a seal between the lid assembly 1500 and the container 1505. However, other sealing methods for sealing the lid assembly 1500 to the container 1505 are contemplated. The lid assembly 1500 may also include an edge 1512 for engaging the opening of the container 1505. The edge 1512 may include a top wall 1514 and a gripping element 1616 extending from the top wall 1514 to assist a user in removing the lid assembly 1500 from the container 1505. As shown, the gripping element 1616 includes a plurality of groove elements extending along the vertical wall 1602 of the edge 1512. These gripping elements 1616 may have any groove geometry (including, among other things, depth, spacing) and are contemplated to be made of the same material or a different material than the edge 1512 elements. Additionally, or alternatively, the gripping element may include a gripping surface geometry different from the grooves shown, such as indentations, protrusions, or a relatively smooth gripping surface.

[0037] The lid assembly 1500 may include a lid 1501 having an intermediate wall 1518 extending below the edge 1512. The upper surface 1520 of the intermediate wall 1518 may define a recess 1522 for receiving the slider mechanism 1502. In one embodiment, as the slider mechanism 1502 moves between the closed and open positions shown in FIG. 15, the recess 1522 can define a guide channel. A first opening 1504 for drinking or pouring liquid from the container can also be formed within the recess 1522. The recess 1522 can also include a second opening 1524. A detent 1526 can extend from the upper surface 1520 of the intermediate wall 1518 into the recess 1522. This detent 1526 is 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, as a result of the user drinking from or pouring through the first opening 1504, it could cause the liquid that may accumulate within the recess 1522 to splash).

[0038] The slider mechanism 1502 may include an upper thread 1530 configured to be positioned within the recess 1522 at the upper surface 1520 of the intermediate wall 118. The upper thread 1530 may include an upper magnet sealed therein. In one embodiment, the upper magnet may be sealed within a cavity in the upper thread 1530 and overmolded with a polymer overmold plug element. Without departing from the scope of these disclosures, additional and alternative sealing methods may be used to secure the upper magnet within the upper thread 1530.

[0039] The slider mechanism 1502 may additionally include a lower thread 1536 configured to be positioned adjacent to the bottom surface 1538 of the intermediate wall 1518 (shown in FIG. 17). Accordingly, FIG. 17 shows the bottom surface 1538 of the intermediate wall 1518. The lower thread 1536 may include a lower thread magnet enclosed therein. In one embodiment, the lower thread magnet may be enclosed within a cavity in the lower thread and may be overmolded with a polymer overmold plug element. Additionally, the slider mechanism 1502 may include a lower gasket 1544 configured to extend around the outer periphery of the lower thread 1536. The lower thread 1536 will be described in further detail in connection with FIGS. 18A and 18B. In one embodiment, the magnetic attraction between the upper thread magnet and the lower thread magnet magnetically couples the upper thread 1530 to the lower thread 1536 across the intermediate wall 1518. Accordingly, manual operation of the upper thread 1530 above the upper surface 1520 of the intermediate wall 1518 results in a sliding movement of the upper thread 1530 and the lower thread 1536.

[0040] FIG. 17 shows a bottom view of the lid assembly 1500 according to one or more aspects described herein. FIG. 17 shows the bottom surface 1538 of the intermediate wall 1518. Accordingly, 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 mountain surface or point 1554 spaced between two valley 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 mountain surface or point 1560 spaced between two valley recesses 1562a and 1562b.

[0041] The lid assembly 1500 additionally includes a recessed pocket 1561 extending to the inner surface 1563 of the sidewall extending under the bottom surface 1538 of the intermediate wall 1518. Accordingly, when the slider mechanism 1502 is in the closed position shown in FIG. 15, the recessed pocket 1561 receives a portion of the lower thread 1536.

[0042] The second opening 1524 may include a detent 1548 that extends from the intermediate wall 1518 to the second opening 1524. When the slider mechanism 1502 is in the closed position shown in FIG. 15, these detents 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 thread 1536. Thus, the detent 1548 is configured to provide an interference fit to prevent the slider mechanism 1502 from being inadvertently moved and thereby inadvertently unsealing the first opening 1504. In one embodiment, the slider mechanism 1502 may be configured to lock in the open configuration and / or the closed configuration. It is further contemplated that in addition to the detent 1548, a locking mechanism may be used to further prevent the slider mechanism 1502 from being inadvertently moved.

[0043] Figures 18A and 18B show an isometric view of the lower thread 1536 according to one or more aspects described herein. The lower thread 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 lower thread ramp 1566. The lower thread ramp 1566 is configured to be received in one of the valley recesses of each of the first ramp feature 1552 and the second ramp feature 1558. Thus, when the slider mechanism 1502 slides between the open configuration and the closed configuration, the lower thread ramp 1566 is configured to slide across the first ramp feature 1552 and the second ramp feature 1558. When the slider mechanism 1502 transitions between the open configuration and the closed configuration, the lower thread ramp 1566 will abut the peak surfaces 1554 and 1560. Further, the peak surfaces 1554 and 1560 are raised with respect to the valley recesses on both sides of the peak surfaces 1554 and 1560, which will urge the upper thread 1530 and the lower thread 1536 to be further separated from each other. Thus, since the magnetic force between the upper thread magnet and the lower thread magnet is inversely proportional to the square of the distance between them, when the lower thread ramp 1566 abuts the peak surfaces 1554 and 1560, the magnetic attraction force will be reduced. In one embodiment, this reduction in magnetic force will provide smooth movement of the slider mechanism 1502 between the open position and the closed position. Further, when the lower thread ramp 1566 is positioned within the valley recesses of the first ramp feature 1552 and the second ramp feature 1558, the relatively shorter distance between the upper thread magnet and the lower thread magnet will result in a relatively stronger magnetic attraction force that helps to fix the slider mechanism 1502 in the open or closed configuration.

[0044] The lower thread 1536 includes curved walls 1646a and 1646b that extend from the inner surface 1564 to the tabs / tab ears 1568a and 1568b. The tab ears 1568a and 1568b are configured to extend through the second opening 1524. The lower thread 1536 further includes a channel 1570 that is configured to receive a portion of the lower gasket 1544. Additionally, the lower thread 1536 includes lower vent channels 1571a and 1571b. Thus, when the slider mechanism 1502 is in the open configuration, one or more of the lower vent channels 1571a or 1571b may provide a channel for air to pass from the external environment through the slider mechanism 1502 into the interior cavity of the container 1505. This air flow path may reduce or prevent gurgling sounds when liquid is being poured from the first opening 1504. Further, the air flow path may be configured to relieve the differential pressure between the interior cavity of the container 1505 and the external environment. Thus, an increased pressure within the interior cavity of the container 1505 can be partially or fully relieved as gas / air can escape through the slider mechanism 1502 into the external environment surrounding the container 1505.

[0045] Additionally, the lower thread 1536 includes a knob air vent 1802 that extends from the sealing surface 1650 through the lower surface 1804 of the knob 1574. The knob air vent can be configured to allow air to pass between the interior cavity of the container 1505 and the external environment surrounding the container 1505. In one embodiment, air can pass through the knob air vent 1802 and through the second opening 1524 to the external environment. In one embodiment, when the lower thread 1536 and the upper thread 1530 move from the closed position shown in FIG. 15 to the open position schematically shown in FIG. 22, the lower thread 1536 separates from the upper thread 1530. This separation unseals the radial ridge 1664 from the sealing surface 1640 and allows air to flow through the knob air vent 1802 between the interior cavity of the container 1505 and the external environment. This knob air vent 1802 can reduce or prevent gurgling sounds due to the relative pressure difference between the interior cavity of the container and the external environment when liquid is being poured from the first opening 1504.

[0046] In one embodiment, the curved walls 1646a and 1656b can be separated by gaps 1648a and 1648b. These gaps 1648a and 1648b can allow air to escape when a portion of the upper thread 1530 contacts the sealing surface 1650 of the lower thread 1536. In one embodiment, the sealing surface 1650 can have a smooth surface texture to enhance the seal between the upper thread 1530 and the lower thread 1536. In one embodiment, the sealing surface 1650 can include a polished surface finish and can be an SPI - A2 finish.

[0047] In one embodiment, the separation distance between the lower surfaces 1652a or 1652b of the tab ears 1568a and 1568b and the inner surface 1564 can be such that the lower thread 1536 cannot be inserted onto the incorrect side of the slider mechanism 1502. Specifically, the separation distance between the lower surfaces 1652a or 1652b of the tab ears 1568a and 1568b and the inner surface 1564 can be less than the wall thickness between the upper surface 1520 and the bottom surface 1538. This geometry prevents the lower thread 1536 from being inserted into the second opening 1524, such that the inner surface 1564 can contact the recess 1522. FIG. 19 shows a configuration where the lower thread 1536 is on the incorrect upper surface 1520 but cannot be fully inserted into the recess 1522.

[0048] FIG. 18B shows an isometric view of the outer surface 1572 of the lower thread 1536. In one embodiment, the knob 1574 extends from the outer surface 1572. This knob 1574 is configured to be gripped by a user to install the slider mechanism 1502 within the lid assembly 1500. The knob 1574 can have a gripping surface finish. In one embodiment, the knob 1574, or a portion thereof, can be formed from a first material, and the remainder of the lower thread 1536 can be formed from a second, different material. In one embodiment, the knob 1574 can have a rubberized outer surface. The lower thread 1536 encloses a lower thread magnet similar to the lower magnet 142. In one embodiment, this lower thread magnet of the lower thread 1536 is enclosed within the knob 1574.

[0049] Figure 20 shows a view of the inside 1582 of the upper thread 1530. The upper thread 1530 includes upper vent channels 1584a and 1584b. When the upper vent channels 1584a and 1584b allow air to pass from the external environment to the slider mechanism 1502, an air vent path between the external environment and the internal cavity of the container 1505 can be completed. Upper thread recesses 1586a and 1586b are configured to receive portions of the tab ears 1568a and 1568b of the lower thread 1536. The cylindrical spacer 1660 extends from the upper thread 1530 and is configured to be received between the curved walls 1646a and 1646b of the lower thread 1536. The cylindrical spacer 1660 includes a lower surface 1662 having a radial ridge 1664. This lower surface 1662 and the radial ridge 1664 are configured to abut against the sealing surface 1650. In one embodiment, the radial ridge 1664 forms a seal at the sealing surface 1640 when the upper thread 1530 is magnetically coupled to the lower thread 1536 when the slider mechanism 1502 is in the closed configuration and / or the open configuration. The radial ridge 1664 can be formed from a rubber material. In one embodiment, the radial ridge 1664 can be formed from a thermoplastic vulcanizate (TPV) material. The upper thread 1530 encloses the upper thread magnet. In one embodiment, this upper thread magnet can be similar to the upper magnet 132. In one embodiment, the upper thread magnet is enclosed within the cylindrical spacer 1660.

[0050] In one implementation form, the slider mechanism may include an upper thread 1530 and a lower thread 1536. As a result, the movement of the upper thread 1530 biases the lower thread 1536 to move in the same direction. This synchronous movement may result from the cylindrical spacer 1660 of the upper thread 1530 that abuts against one or more surfaces of the curved walls 1646a and 1646b of the lower thread 1536. In one example, the synchronous movement of the upper thread 1530 and the lower thread 1536 may not utilize a magnet to bias the upper thread 1530 towards the lower thread 1536. In one example, the upper thread 1530 and / or the lower thread 1536 may be implemented without a magnet element. As a result, there is no magnetic attraction force between the upper thread 1530 and the lower thread 1536.

[0051] Figures 21A and 21B show an isometric view and a partial cross-sectional view of the lower gasket 1544 according to one or more aspects described herein. Thus, when the slider mechanism 1502 is in the closed configuration shown in FIG. 15, the lower gasket 1544 is configured to seal the first opening 1504. Additionally, the lower gasket 1544 is configured to seal the second opening 1524. In one example, the inner surface 1588 of the lower gasket 1544 is configured to be positioned on the outer surface 1572 of the lower thread 1536. The opening 1590 in the lower gasket 1544 is configured to allow the knob 1574 of the lower thread 1536 to extend therethrough. In one example, the lower gasket 1544 may be composed of silicone. However, additional or alternative polymeric materials may be used without departing from the scope of these disclosures. In one example, the lower gasket 1544 may be integrally formed with the bottom slider 1536. Thus, the lower gasket 1544 may be formed from the same or different materials onto the bottom slider 1536 using a single-stage or multi-stage (single-shot or multi-shot) molding process.

[0052] In one embodiment, and as shown in the elevation view of 21B, the lower gasket 1544 may have a lip 1692 that extends further from the inner surface 1588 than the comparable spring feature 192 of the lower gasket 144. Thus, the lip 1692 may provide enhanced sealing when the lower gasket 1544 is positioned against the bottom surface 1538 of the lid 1501.

[0053] FIG. 22 schematically shows the lid assembly 1500 in an open configuration. In one embodiment, the back wall 1690 of the recess 1522 is configured to abut the upper thread 1530 when positioned in the open configuration of FIG. 22. Thus, when in the open configuration shown, the lower ramp 1566 may be held on the peak surfaces 1554 (and 1560). In this configuration, the lower gasket 1544 may be spaced from the bottom surface 1538 such that air can flow between the internal cavities of the container 1505, through the lid assembly 1500, to the external environment, thereby preventing or limiting gurgling sounds during pouring.

[0054] Figures 23 - 40 illustrate another implementation of the lid assembly 2000 configured to be removably coupled to the container 1505, according to one or more aspects described herein. The lid assembly 2000 may be interchangeable with the lid assembly 1500 or the lid assembly 100, such that the lid assembly 2000 may be removably coupled to the container 105, the container 1505, or other similar containers. The lid assembly 2000 may include a plurality of elements similar to the lid assembly 100 and the lid assembly 1500, such that the reference numbers used to describe the features of the lid assembly 2000 may include elements of similar features described in relation to those lid assemblies 100 and 1500, if those features are labeled such that the first two digits are "20" and the last two digits are the same. For example, the slider mechanism 1502 described in relation to the lid assembly 1500 may be similar to the slider mechanism 2002, since both elements are denoted by labels ending with "02". Additionally, the features of the lid assembly 2000 may include features labeled such that the first two digits are "21" or "22" and the last two digits are the same as those shown in relation to the lid assembly 1500 having first two digits of "16" or "18", respectively. Because the features are similar, these features may be described less fully or not at all with respect to the lid assembly 2000. Additional, alternative, or differentiating features of the elements of the lid assembly 2000 with respect to the elements of the lid assemblies 100 and 1500 may be noted in the following description.

[0055] Figures 23 - 34 show the lid assembly 2000. The lid 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 a container can flow. The lid assembly 2000 may additionally include a side wall 2006, which may define a groove 2008 for placement of a gasket 2010. Thus, the gasket 2010 may provide a seal between the lid assembly 2000 and the container. However, other sealing methods for sealing the lid assembly 2000 to the container are also contemplated. The lid assembly 2000 may also include an edge 2012 for engaging an opening of the container. The edge 2012 may also include a top wall 2014 and a gripping element 2116 and / or an optional lid tab (not shown) extending from the top wall 2014 to assist a user in removing the lid assembly 2000 from the container.

[0056] The lid assembly 2000 may include a lid 2001 having an intermediate wall 2018 extending beneath the edge 2012. The upper surface 2020 of the intermediate wall 2018 may define a recess 2022 for receiving the slider mechanism 2002. In one embodiment, the recess 2022 can define a guide channel as the slider mechanism 2002 moves between the closed position shown in Figure 23 and the open position. The first opening 2004 for drinking or pouring liquid from the container can also be formed within the recess 2022. The recess 2022 may also include a second opening 2024.

[0057] The slider mechanism 2002 may include an upper thread 2030 configured to be positioned within the recess 2022 on the upper surface 2020 of the intermediate wall 2018. The upper thread 2030 may include an upper magnet sealed therein. In one embodiment, the upper magnet may be sealed within a cavity in the upper thread 2030 and overmolded with a polymer overmold plug element. Without departing from the scope of these disclosures, additional and alternative sealing methods may be used to secure the upper magnet within the upper thread 2030.

[0058] The slider mechanism 2002 may additionally include a lower thread 2036 configured to be positioned adjacent to the bottom surface 2038 of the intermediate wall 2018 (shown in FIG. 32). Accordingly, FIG. 36 shows the bottom surface 2038 of the intermediate wall 2018. The lower thread 2036 may include a lower thread magnet sealed therein. In one embodiment, the lower thread magnet may be sealed within a cavity in the lower thread 2036 and overmolded with a polymer overmold plug element. Additionally, the slider mechanism 2002 may include a lower gasket 2044 configured to extend around the outer periphery of the lower thread 2036. The lower thread 2036 is described in further detail with respect to FIGS. 38-40. In one embodiment, the magnetic attraction between the upper thread magnet and the lower thread magnet magnetically couples the upper thread 2030 to the lower thread 2036 across the intermediate wall 2018. Accordingly, manual operation of the upper thread 2030 above the upper surface 2020 of the intermediate wall 2018 results in a sliding movement of the upper thread 2030 and the lower thread 2036.

[0059] As best shown in FIG. 35, the recess 2022 may include a tapered surface 2025 between the first opening 2004 and the second opening 2024. This tapered surface 2025 may suggest that the first depth of the recess 2022 near and / or adjacent to the first opening 2004 may be greater than the second depth adjacent to the second opening 2024. The tapered surface 2025 may extend to either or both sides of the first opening 2004. Additionally, the tapered surface 2025 may extend to either or both sides of a portion of the second opening 2024. The tapered surface 2025 may, as discussed in more detail below, enable the front portion 2031 of the upper thread 2030 to tilt downwardly into a region on the tapered surface 2025, initiating actuation of the slider mechanism 2002 from the closed position to the open position.

[0060] The upper surface 2023 of the recess 2022 may further include a pair of engagement members 2170. Each engagement member 2170 may include a first inclined surface 2172 and a second inclined surface 2174 arranged adjacent to each other. The pair of engagement members 2170 may be spaced apart from each other and arranged substantially parallel to each other. In addition, most of each engagement member 2170 may be positioned behind the second opening 2024. In some embodiments, the entirety of each engagement member 2170 may be positioned behind the second opening 2024. Each engagement member 2170 may be individually received within respective channels 2180 that may be disposed along the lower surface of the upper thread 2030. Each channel 2180 of the lower thread may include a rear channel engagement member 2182. When the slider mechanism 2002 is in the closed position, each rear channel engagement member 2182 may be 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 may be behind the engagement member 2170. The interaction between the engagement members 2170 and their respective receiving channels 2180 may help to guide the slider mechanism 2002 in its forward and backward movement. In addition, the engagement members 2170 and the rear channel engagement members 2182 may contact each other and act as stops to limit or restrict the movement of the slider mechanism 2002 and prevent accidental opening of the lid assembly 2000. The illustrated lid assembly 2000 shows two engagement members 2170, but the lid 2001 may include a single engagement member 2170 that is substantially centered longitudinally within the recess 2022 and positioned behind the second opening 2024. This single engagement member 2170 may be received within a centrally located channel 2180 that extends along the lower surface of the upper thread 2030.

[0061] Additionally, for each engagement member 2170, the first inclined surface 2172 may be disposed at a location where a first angle between the upper surface 2023 and the first inclined surface 2172 (the first angle may be defined counterclockwise as the angle between the upper surface 2023 and the first inclined surface 2172) is greater than a second angle of the upper surface 2023 and the second inclined surface 2174 (the second angle may be defined clockwise as the angle between the upper surface 2023 and the second inclined surface 2174). Similarly, each rear channel engagement member 2182 may have a first inclined surface 2184 and a second inclined surface 2186 disposed adjacent to each other. The first inclined surface 2184 may be disposed at a location where a first angle between the bottom channel surface 2185 and the first inclined surface 2184 (the first angle may be defined counterclockwise as the angle between the bottom channel surface 2185 and the first inclined surface 2184 when the upper thread 2030 has a bottom channel surface 2185 facing upward) is less than a second angle of the bottom channel surface 2185 to the second inclined surface 2186 (the second angle may be defined clockwise as the angle between the bottom channel surface 2185 and the second inclined surface 2186 when the upper thread 2030 has a bottom channel surface 2185 facing upward). When the slider mechanism 2002 is in the closed position, each second inclined surface 2174 of each engagement member 2170 may face the first inclined surface 2184 of each rear channel engagement member 2182. When the slider mechanism 2002 is in the open position, each first inclined surface 2172 of each engagement member 2170 may face the second inclined surface 2186 of the rear channel engagement member 2182.

[0062] Each channel 2180 may extend through the front 2190 of the upper thread 2030 and may also extend through the back 2192 of the upper thread 2030. Each channel 2180 may be intermittent, and as a result, does not extend continuously from the front 2190 to the back 2192. Each channel 2180 may be disposed on either side of the cylindrical spacer 2160 or may be interrupted by the cylindrical spacer 2160. In an alternative embodiment, each channel 2180 may be continuous from the front 2190 to the back 2192. Each channel 2180 may be spaced apart from each other and may be substantially parallel to each other. In addition, 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 may be a mirror image of the rear channel engagement member 2182 with respect to a plane that is perpendicular to the channel 2180 and extends through the center of the upper thread 2030. Since the channel engagement members 2182, 2196 are positioned as mirror images, the upper thread 2030 may be assembled in a plurality of orientations.

[0063] In addition to the interaction of the channels 2180 and the engagement members 2170, the slider mechanism 2002 may also interact with the lid 2001 in a manner similar to the slider mechanism 1502 and the lid 1501. For example, as shown in FIG. 36, the lid 2001 may have a bottom surface 2038 of an intermediate wall 2018 that includes a first inclined feature 2052 on a first side of the second opening 2024 and a second inclined feature 2058 disposed on an opposite side of the second opening 2024. The first inclined feature 2052 has a mountain surface or point 2054 that is spaced between two valley recesses 2056a and 2056b. Similarly, the second inclined feature 2058 may include a mountain surface or point 2060 that is spaced between two valley recesses 2062a and 2062b.

[0064] Figures 33A - 33F show a process for a user to move the slider mechanism 2002 from the closed position shown in Figure 33A to the fully open position shown in Figure 33F. The first step in the process shown in Figure 33B shows the slider mechanism 2002 moving slightly rearward from the closed position when the user begins to apply a rearward force but further movement is prevented by the engagement member 2170. Next, in Figure 33C, the user can press downward on the front portion 2031 of the upper thread 2030, thereby moving the rear portion 2033 upward. As the rear portion 2033 moves upward, any gas or fluid that may be under pressure between the upper thread 2030, the lower thread 2036, and the container can be vented outward from the rear of the upper thread 2030 away from where the user can place their mouth to drink from the lid 2001. For example, as the upper thread 2030 tilts, the sealing surface 2150 of the lower thread releases from the radial ridge 2164 of the lower surface 2162 of the upper thread 2030 and can cause the release of any pressurized gas or liquid within the container. Next, as shown in Figures 33D and 33E, as the user applies a rearward force to the slider mechanism 2002, the first inclined surface 2184 of the rear channel engagement member 2182 slides along the second inclined surface 2174 of the engagement member 2170, allowing the rear channel engagement member 2182 to slide and then move beyond the engagement member 2170. At the same time, the lower inclined thread 2066 of the lower thread 2036 begins to move from the first valley recess 2056a towards the second valley recess 2056b. In the final step of the opening process shown in Figure 33F, the user can continue to apply a rearward force until the lower inclined thread 2066 engages the second valley recess 2056b and / or the back surface 2192 of the upper thread 2030 contacts the upper surface of the indentation 2022. The lid assembly 2000 is now in the open position and is 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 thread 2030. The second inclined surface 2184 slides up to and then along the first inclined surface 2172 as shown in Figure 34.The upper thread 2030 then moves to cover the first opening 2004 and move the slider mechanism 2002 into the closed position as shown in FIG. 33A.

[0065] FIG. 37 shows a view of the upper thread 2030. The upper thread 2030 may include upper vent channels 2084a and 2084b. When the upper vent channels 2084a and 2084b allow air to pass from the external environment to the slider mechanism 2002, this vent path between the external environment and the internal cavity of the container is completed. The upper thread recesses 2086a and 2086b are configured to receive portions of the tab ears 2068a and 2068b of the lower thread 2036. The cylindrical spacer 2160 extends from the upper thread 2030 and is configured to be received between the curved walls 2046a and 2046b of the lower thread 2036. The cylindrical spacer 2160 includes a lower surface 2162 having a radial ridge 2164. The lower surface 2162 and the radial ridge 2164 are configured to abut against the sealing surface 2150 of the lower thread 2036. In one embodiment, the radial ridge 2164 forms a seal at the sealing surface 2150 when the upper thread 2030 is magnetically coupled to the lower thread 2036 when the slider mechanism 2002 is in the closed configuration and / or the open configuration. The radial ridge 2164 may be formed from a compliant material such as a rubber-based material. In one embodiment, the radial ridge 2164 may be formed from a thermoplastic vulcanizate (TPV) material. The upper thread 2030 may enclose an upper thread magnet. In one embodiment, this upper thread magnet may be similar to the upper magnet 132. In one embodiment, the upper thread magnet is enclosed within the cylindrical spacer 2160.

[0066] Figures 38 to 40 show the lower thread 2036. The lower thread 2036 may include an inner surface 2064 configured to be positioned adjacent to the bottom surface 2038 of the intermediate wall 2018. The lower thread 2036 may have features similar to the lower thread 1536, such as a lower inclined thread 2066 configured to be received within one of the valleys of each of the first inclined feature 2052 and the second inclined feature 2058. Thus, when the slider mechanism 2002 slides between the open configuration and the closed configuration, the lower inclined thread 2066 is configured to slide across the first inclined feature 2052 and the second inclined feature 2058. Additionally, the lower thread 2036 may also include curved walls 2146a and 2146b extending from the inner surface 2064 to the tabs / tab ears 2068a and 2068b. The tab ears 2068a and 2068b are configured to extend through the second opening 2024. The lower thread 2036 further includes a channel 2070 configured to receive a portion of the lower gasket 2044. Additionally, the lower thread 2036 includes lower ventilation channels 2071a and 2071b, which may provide a channel for air to pass from the external environment, through the slider mechanism 2002, and into the internal cavity of the container. This air flow path may reduce or prevent gurgling sounds when liquid is being poured from the first opening 2004. Further, the air flow path may be configured to relieve the differential pressure between the internal cavity of the container and the external environment. Thus, the increased pressure within the internal cavity of the container can be partially or completely relieved as gas / air can escape to the external environment surrounding the container through the slider mechanism 2002. This ventilation can also occur when the slider mechanism 2002 is tilted when being moved from the closed position to the open position, as discussed above.

[0067] Additionally, the lower thread 2036 includes a knob air vent 2202 that extends from the sealing surface 2150 through the lower surface 2204 of the knob 2074. The knob air vent 2202 can be configured to allow air to pass between the internal cavity of the container and the external environment surrounding the container. In one embodiment, air can pass through the knob air vent 2202 and through the second opening 2024 to the external environment. In one embodiment, when the lower thread 2036 and the upper thread 2030 move from the closed position as shown in FIG. 33A to the open position schematically shown in FIG. 33F, the lower thread 2036 is unsealed from the radial ridge 2164 from the sealing surface 2150, allowing air to flow through the knob air vent 2202 between the internal cavity of the container and the external environment. This knob air vent 2202 can reduce or prevent gurgling sounds due to the relative pressure difference between the internal cavity of the container and the external environment when liquid is being poured from the first opening 2004.

[0068] As shown in FIG. 40, the knob air vent 2202 may have a knob air vent 2202 that extends from the sealing surface 2150 to the lower surface 2204. The knob air vent 2202 may include a first ventilation opening 2206 in the lower surface 2204, a second ventilation opening 2208 in the sealing surface 2150, and a ventilation inner surface 2210 between the first ventilation opening 2206 and the second ventilation opening 2208. The knob air vent 2202 may have a first rounded entry portion 2212 (i.e., fillet radius) that transitions from the lower surface 2204 to the ventilation inner surface 2210. Similarly, the knob air vent 2202 may have a second rounded entry portion 2214 (i.e., fillet radius) that transitions from the sealing surface 2150 to the ventilation inner surface 2210 at the second ventilation opening 2208. By adding the rounded entry portions 2212, 2214, the pressure rise between the upper thread 2030 and the lower thread 2036 can be reduced. In some embodiments, the first ventilation opening 2206 may have a second ventilation opening 2208 that may have a first diameter and a second diameter, and the first diameter may be smaller than the second diameter. Further, the ratio of the first diameter to the second diameter may be in the range of about 0.8:1.0 or 0.7:1.0 to 0.9:1.0. Additionally, the ventilation inner surface 2210 may include a tapered or conical surface that expands as it moves from the first rounded entry portion 2212 to the second rounded entry portion 2214, or the ventilation inner surface 2210 may be substantially cylindrical. The third diameter measured in the smallest region along the ventilation inner surface 2210 (i.e., between the first diameter and the second diameter) 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 may 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 may be the ratio of the third diameter to the first diameter. For example, the ratio of the third diameter to the first diameter may be about 0.27:1.0, or may be in the range of 0.2:1.0 to 0.3:1.0, or may be in the range of 0.2:1 to 0.5:1.0. In some embodiments, the first rounded portion may have a radius in the range of about 2.9 mm or 2.5 to 3.5 mm, while the second rounded portion may have a radius in the range of about 3.8 mm or 3.5 to 4.5 mm. The radius of the first rounded entry portion 2212 may be smaller than the radius of the second rounded entry portion 2214.Another way to represent the sizes of the rounded entry portions 2212, 2214 is the ratio of the radius of the first rounded entry portion 2212 to the radius of the second rounded entry portion 2214. For example, the ratio of the radius of the first rounded entry portion 2212 to the radius of the second rounded entry portion 2214 can be about 0.76:1, or can be within the range of 0.7:1 to 0.8:1. The geometry of the air vent 2202 can allow air to be released from the container at a rate that prevents any opposing pressure build-up between the contents of the container and the slider mechanism 2002.
