Definitions
- the present disclosure herein relates broadly to lids for drinkware, and more specifically to closeable lids for drinkware containers used for drinkable beverages or foods.
- Beverage containers can be filled with hot or cold drinkable liquids, such as water, coffee, tea, soft drink, or alcoholic beverage, such as beer.
- These beverage containers can be made of a variety of materials such as stainless steel, glass, plastic, cardboard, or paper material. Lids may be provided on beverage containers to provide an opening for pouring out the contents of the beverage container. In certain instances, it can be desired to selectively close and store the container such that the contents of the container do not spill.
- WO 2020/086567 A1 discloses a lid assembly according to the prior art.
- the lid assembly can include a manually movable slider, which may include a tab or handle.
- the slider can be configured to perform one or more of the following: slide between a closed position and an open position where the slider covers an opening to aid in preventing spilling of contents of the container and an opened position where the slider uncovers the opening such that the contents of the container can be consumed, remain secured to the lid during movement between the closed position and the opened position, and to be removable from the lid so that the lid and slider can be cleaned.
- FIG. 1 depicts an isometric view of a lid assembly 100 that is removably coupled to a container 105, according to one or more aspects described herein.
- Container 105 is one example container to which the lid assembly 100 may be configured to be removably coupled. Accordingly, the container 105 may be configured to store a volume of liquid and the lid assembly 100 may be configured to seal an opening of the container 105.
- FIGS. 2A and 2B depict isometric views of the lid assembly 100 in a closed and an open configuration, respectively.
- the lid assembly 100 generally includes a slider mechanism 102 that is configured to move between a closed position (depicted in FIG. 2A ) and an open position (depicted in FIG. 2B ) to selectively close or open a first opening 104 through which a liquid, stored in the container 105, is configured to flow. Further details of the slider mechanism 102 are discussed in relation to the proceeding figures.
- the lid assembly 100 includes a sidewall 106, which defines a groove 108 for placement of a gasket 110. Accordingly, the gasket 110 may provide a seal between the lid assembly 100 and the container 105.
- the lid assembly 100 includes a rim 112 for engaging an opening of the container 105.
- the rim 112 includes a top wall 114 and grip elements 116 and/or an optional lid tab (not depicted) extending from the top wall 114 to assist the user in removing the lid assembly 100 from the container 105.
- the lid assembly 100 includes a middle wall 118 extending below the rim 112.
- a top surface 120 of the middle wall 118 defines a recess 122 for receiving the slider mechanism 102.
- the recess 122 can define a guide channel as the slider mechanism 102 moves between the closed position depicted in FIG. 2A and the open position depicted in FIG. 2B .
- the first opening 104 for drinking or pouring liquid out of the container is formed in the recess 122.
- the recess 122 includes a second opening 124, which is described in further detail in relation to FIG. 5A .
- a detent 126 may extend into from the top surface 120 of the middle wall 118 into the recess 122.
- This detent 126 may be configured to abut the slider mechanism 102 when in the open position depicted in FIG. 2B to prevent liquid from being compressed between the slider mechanism 102 and an end wall 128 of the recess 122, which may otherwise result in splashing of a liquid that may pool in the recess 122 as a result of a user drinking or pouring from the first opening 104.
- FIG. 3 schematically depicts an exploded isometric view of the lid assembly 100, according to one or more aspects described herein.
- FIG. 3 schematically depicts multiple elements that make up the slider mechanism 102, as discussed in relation to FIGS. 2A and 2B .
- the slider mechanism 102 includes an upper sled 130, which is configured to be positioned within the recess 122 on the top surface 120 of the middle wall 118.
- the upper sled 130 includes an upper magnet 132 that is encapsulated therein.
- the upper magnet 132 may be encapsulated within a cavity in the upper sled 130, and may be overmolded with a polymeric overmold plug element 134.
- the upper magnet 132 may be formed of any suitable ferromagnetic or otherwise magnetic material.
- the upper sled 130 is discussed in further detail in relation to FIGS. 7A and 7B .
- the slider mechanism 102 additionally includes a lower sled 136 that is configured to be positioned adjacent to a bottom surface 138 of the middle wall 118 (depicted in FIG. 5B ).
- the lower sled 136 includes a lower sled magnet 140 that is encapsulated therein.
- the lower sled magnet 140 may be encapsulated within a cavity in the lower sled 136, and may be overmolded with a polymeric overmold plug element 142.
- the slider mechanism 102 may include a lower gasket 144 that is configured to extend around a perimeter of the lower sled 136.
- the lower sled 136 is described in further detail in relation to FIGS. 6A and 6B .
- FIG. 4 schematically depicts a cross-sectional view through the lid assembly 100, according to one or more aspects described herein.
- the slider mechanism 102 is in a closed configuration such that the first opening 104 is sealed by the slider mechanism 102.
- the lower sled magnet 140 may have a cylindrical geometry with a hollow center.
- the lower sled magnet 140 may otherwise be described as a ring magnet that extends around a central tube 146 through the overmolded plug element 142 and the lower sled 136.
- the lower sled magnet 140 may have a solid cylindrical geometry.
- FIGS. 5A and 5B depict isometric views of the lid assembly 100 without the slider mechanism 102.
- FIG. 5A depicts a view of the top surface 120 of the middle wall 118
- FIG. 5B depicts a view of the bottom surface 138 of the middle wall 118.
- the lid mechanism 100 includes a first opening 104 and a second opening 124.
- a portion of the slider mechanism 102 is configured to extend through the second opening 124 when the upper sled 130 is magnetically coupled to the lower sled 136.
- the second opening 124 may include detents 148 that extend from the middle wall 118 into the second opening 124. These detents 148 are configured to be received into channels 150 (see FIG. 6A ) extending along a portion of the central tube 146 of the lower sled 136 when the slider mechanism 102 is in the closed position depicted in FIG. 2A . Accordingly, the detents 148 are configured to provide an interference fitting to prevent the slider mechanism 102 from being inadvertently moved and thereby inadvertently unseal the first opening 104. In one example, the slider mechanism 102 may be configured to lock in the open and/or closed configuration depicted in FIGS. 2A and 2B . It is further contemplated that a locking mechanism in addition to the detents 148 may be used to further prevent the slider mechanism 102 from being inadvertently moved.
- FIG. 5B depicts the bottom surface 138 of the middle wall 118. Accordingly, as depicted, the bottom surface 138 defines a first ramped feature 152 on a first side of the second opening 124. The first ramped feature 152 having a crest surface 154 spaced between two trough depressions 156. Similarly, a second ramped feature 158 is positioned on a second side of the second opening 124. The second ramped feature 158 includes a crest surface 160 spaced between two trough depressions 162.
- the lid assembly 100 additionally includes a recess pocket 161 extending into an inner surface 163 of the sidewall that extends below the bottom surface 138 of the middle wall 118. Accordingly, the recess pocket 161 receives a portion of the lower sled 136 when the slider mechanism 102 is in the closed position depicted in FIG. 2A .
- the lid assembly 100 also includes a recessed vent pocket 165, such that the geometry of the recessed vent pocket 165 allows air to flow into the container 105 as a liquid is being poured out of the first opening 104.
- FIGS. 6A and 6B depict isometric views of the lower sled 136, according to one or more aspects described herein.
- the lower sled 136 includes an inner surface 164 that is configured to be positioned adjacent to the bottom surface 138 of the middle wall 118.
- the inner surface 164 includes a lower sled ramp 166.
- the lower sled ramp 166 is configured to be received into one of the trough depressions of each of the first ramped feature 152 and the second ramped feature 158.
- the lower sled ramp 166 is configured to slide across the first ramped feature 152 and the second ramped feature 158 as the slider mechanism 102 slides between the open and close configurations.
- the lower sled ramp 166 will abut the crest surfaces 154 and 160. Further, because the crest surfaces 154 and 160 are raised relative to the trough depressions on either side of the crest surfaces 154 and 160, this will urge the upper sled 130 and the lower sled 136 to space further apart from one another. As such, because the magnetic force between the upper sled magnet 132 and the lower sled magnet 140 is inversely proportional to the square of the distance between them, the magnetic attractive force will be reduced when the lower sled ramp 166 abuts the crest surfaces 154 and 160. In one example, this reduction in magnetic force will provide for smooth movement of the slider mechanism 102 between the open and closed positions.
- the comparatively shorter distance between the upper sled magnet 132 and the lower sled magnet 140 will result in a comparatively stronger magnetic attractive force that serves to secure the slider mechanism 102 in the open or closed configuration.
- the lower sled 136 and the upper sled 130 are symmetrical about to perpendicular axes in order to allow the slider mechanism to be installed in the lid assembly 100 in any of four different ways.
- the lower sled 136 additionally includes a central tube 146 that extends from the inner surface 164. Further, the central tube 146 includes tab ears 168 that are configured to extend through the second opening 124.
- the lower sled 136 further includes a channel 170 that is configured to receive a portion of the lower gasket 144. Additionally, the lower sled 136 includes lower vent channels 171a and 171b.
- a portion of the lower sled 136 extends over a portion of the recessed vent pocket 165.
- one of the lower vent channels 171a or 171b is positioned over the recessed vent pocket 165, and thereby sets up a channel by which air can pass from the slider mechanism 102 into an internal cavity of the container 105.
- FIG. 6B depicts an isometric view of an outer surface 172 of the lower sled 136.
- a knob 174 otherwise referred to as finger tabs 174 extend from the outer surface 172.
- This knob 174 is configured to be gripped by a user in order to install the slider mechanism 102 in the lid assembly 100. This installation process is described in further detail in relation to FIG. 12 .
- FIGS. 7A and 7B depict isometric views of the upper sled 130.
- the upper sled 130 can include two symmetrical flanges 176a and 176b, which are both configured to selectively cover and seal the first opening 104 for pouring liquid out of the container and the second opening 124 in the recess 122, otherwise referred to as a guide channel 122.
- the tab or the handle 178 is configured for the user to grasp to selectively move the upper sled 130, and thereby the slider mechanism 102, into an opened position to uncover the first opening 104 on the lid assembly 100 or closed position to cover the first opening 104 on the lid assembly 100.
- the tab or handle 178 may include two inwardly tapered portions 180a and 180b for grasping purposes.
- FIG. 7B depicts a view of an inner side 182 of the upper sled 130.
- the upper sled 130 includes upper vent channels 184a and 184b. Accordingly, when the slider mechanism 102 is in the open configuration, a vent path is partially formed by a portion of the lower sled 136 extending over a portion of the recessed vent pocket 165. Additionally, one of the lower vent channels 171a or 171b is positioned over the recessed vent pocket 165, and thereby sets up a channel through which air can pass from the slider mechanism 102 into an internal cavity of the container 105.
- This vent path between an external environment and the internal cavity of the container 105 is completed as the upper vent channels 184a and 184b allow air to pass from the external environment into the slider mechanism 102.
- the upper sled recesses 186a and 186b are configured to receive a portion of the tab ears 168 of the lower sled 136.
- FIGS. 8A and 8B depict an isometric and a partial cross-sectional view of the lower gasket 144, according to one or more aspects described herein.

- the opening 190 in the lower gasket 144 is configured to allow the knob 174 of the lower sled 136 to extend through.
- the lower gasket 144 may be constructed from silicone. However, additional or alternative polymeric materials may be used, without departing from the scope of these disclosures.
- FIG. 8B The cross-sectional view of FIG. 8B indicates the spring feature 192 of the lower gasket 144. Accordingly, the spring feature 192 allows the seal formed by the gasket 144 to move and stay in contact with the bottom surface 138 of the middle wall 118. Accordingly, when in the open or closed configurations, the comparatively high magnetic force urging the lower sled 136 toward the bottom surface 138 of the middle wall 118 compresses the spring feature 192 of the lower gasket 144.
- the spring feature 192 extends out toward and maintains contact with the bottom surface 138 to maintain the seal of the lower gasket 144 on the bottom surface 138.
- FIGS. 9A and 9B schematically depict cross-sectional views of the lid assembly 100 in a closed configuration.
- the slider mechanism 102 that includes the upper sled 130 and the lower sled 136 is sealing the first opening 104.
- FIG. 9B depicts a more detailed view of a portion of the cross-section of FIG. 9A . Accordingly, FIG. 9B depicts a portion of the lower sled 136 and the lower gasket 144 received into the recess pocket 161 of the lid assembly 100.
- FIGS. 10A and 10B schematically depict cross-sectional views of the lid assembly 100 in an open configuration.

- FIG. 10B depicts 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 on the portion of the recessed vent pocket 165 results in a gap 192 through which the air can enter into the container 105 as liquid is being poured from the first opening 104.
- FIGS. 11A and 11B schematically depict cross-sectional views of the lid assembly 100 in a partially-open configuration.
- the first opening 104 is partially uncovered by the slider mechanism 102 that includes the upper sled 130 and the lower sled 136.
- FIG. 11B schematically depicts a more detailed view of a portion of the cross-section of FIG. 11A .
- FIG. 11B depicts a separation 196, or gap 196 between the upper sled 130 and the lower sled 136. This separation 196 results from the lower sled ramp 166 abutting the crest surfaces 154 and 160, as previously described.
- FIGS. 12A-12D depict various steps for disassembly of the slider mechanism 102 and removal from the lid assembly 100.
- the slider mechanism 102 includes the upper sled 130 and the lower sled 136.
- the upper sled includes the upper sled magnet 132
- the lower sled 136 includes the lower sled magnet 140 and lower gasket 144.
- FIG. 12A depicts the lid assembly 100 with the slider mechanism 102 fully installed and in an open configuration.
- the upper sled 130 may be manually lifted from the top surface 120.
- FIG. 12B depicts the upper sled 130 after having being removed from the top surface 120.
- the lower sled 136 is no longer held against the bottom surface 138 by the magnetic attractive force between the upper sled magnet 132 and the lower sled magnet 140.
- tab ears 168 prevent the lower sled 136 from falling into the container 105 as the tab ears 168 extend through the second opening 124 and grip onto a portion of the top surface 120.
- FIG. 12D depicts the upper sled 130 and lower sled 136 fully removed from the lid assembly 100.
- FIG. 13 schematically depicts a cross-sectional view of a portion of the lid assembly 100 coupled to a container 105.
- the lid assembly 100 may be resealably coupled to the container 105 by threaded elements on both the sidewall 106 of the lid assembly 100, and a sidewall 202 of the container 105. Elements 204 and 206 are threads on the sidewalls 106 and 202, respectively. Further, it is contemplated that any thread geometries may be used to secure the lid assembly 100 to the container 105, without departing from the scope of these disclosures.
- the various lid assembly 100 structures described throughout this disclosure may be implemented without a threaded coupling between the lid assembly 100 and the container 105.

- the lower sled 306 is slid to the position depicted in FIG. 14C , such that the geometry of the tab ears 308 aligns with the geometry of an opening 309 in the middle wall 310 of the lid assembly 300.
- the lower sled 306 can pass through the opening 309, as depicted in FIG. 14D.
- FIG. 14E depicts the upper sled 302 and lower sled 306 fully removed from the lid assembly 300.
- FIG. 15 depicts another implementation of a lid assembly 1500 that is configured to be removably coupled to a container 1505, according to one or more aspects described here.
- the lid assembly 1500 and container 1505 may be interchangeable with lid assembly 100 and container 105, such that lid assembly 1500 may be removably coupled to container 105 and lid assembly 100 may be removably coupled to container 1505.
- the lid assembly 1500 may include multiple elements similar to lid assembly 100, such that reference numerals used to described features of lid assembly 1500 may include elements of similar features described in relation to lid assembly 100, if those features are labelled with the first two digits being "15" and the final two digits being the same as those described in relation to lid assembly 100.
- slider mechanism 102 described in relation to lid assembly 100 may be similar to slider mechanism 1502, since both elements are denoted with labels ending in "02." Additional, alternative or distinguishing features of the elements of lid assembly 1500 over those of lid assembly 100 may be noted in the proceeding descriptions.
- FIG. 16 schematically depicts an exploded view of multiple elements of the lid assembly 1500, according to one or more aspects described herein.
- the lid assembly 1500 generally includes a slider mechanism 1502 that is configured to move between a closed position (depicted in FIG. 15 ) and an open position to selectively close or open a first opening 1504 through which a liquid, stored in the container 1505, is configured to flow.
- the lid assembly 1500 includes a sidewall 1506, which defines a groove 1508 for placement of a gasket 1510. Accordingly, the gasket 1510 may 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 also contemplated.
- the lid assembly 1500 includes a rim 1512 for engaging an opening of the container 1505.
- the rim 1512 includes a top wall 1514 and grip elements 1616 extending from the top wall 1514 to assist the user in removing the lid assembly 1500 from the container 1505.
- the grip elements 1616 include multiple groove elements extending along a vertical wall 1602 of the rim 1512. It is contemplated that these grip elements 1616 may have any groove geometries (depth, spacing, among others) and may be made from a same material or a different material to the rim 1512 element. Additionally or alternatively, the grip elements may include different grip surface geometries to the depicted grooves, such as dimples, protrusions, or a relatively smooth grip surface.
- the lid assembly 1500 includes a lid 1501 with a middle wall 1518 extending below a rim 1512.
- a top surface 1520 of the middle wall 1518 defines a recess 1522 for receiving the slider mechanism 1502.
- the recess 1522 can define a guide channel as the slider mechanism 1502 moves between the closed position depicted in FIG. 15 and an open position.
- the first opening 1504 for drinking or pouring liquid out of the container is formed in the recess 1522.
- the recess 1522 also includes a second opening 1524.
- a detent 1526 may extend from the top surface 1520 of the middle wall 1518 into the recess 1522.
- This detent 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 an end wall 1528 of the recess 1522, which may otherwise result in splashing of a liquid that may pool in the recess 1522 as a result of a user drinking or pouring from the first opening 1504.
- the slider mechanism 1502 includes an upper sled 1530, which is configured to be positioned within the recess 1522 on the top surface 1520 of the middle wall 118.
- the upper sled 1530 includes an upper magnet that is encapsulated therein.
- the upper magnet may be encapsulated within a cavity within the upper sled 1530, and may be overmolded with a polymeric overmold plug element. Additional or alternative encapsulation methods may be used to secure the upper magnet within the upper sled 1530, without departing from the scope of these disclosures.
- the slider mechanism 1502 includes a lower sled 1536 that is configured to be positioned adjacent to a bottom surface 1538 of the middle wall 1518 (depicted in FIG. 17 ). Accordingly, FIG. 17 depicts the bottom surface 1538 of the middle wall 1518.
- the lower sled 1536 includes a lower sled magnet that is encapsulated therein. In one example, the lower sled magnet may be encapsulated within a cavity in the lower sled, and may be overmolded with a polymeric overmold plug element. Additionally, the slider mechanism 1502 may include a lower gasket 1544 that is configured to extend around a perimeter of the lower sled 1536.
- the lower sled 1536 is described in further detail in relation to FIGS.
- FIG. 17 depicts a bottom view of the lid assembly 1500, according to one or more aspects described herein.
- FIG. 17 depicts the bottom surface 1538 of the middle wall 1518. Accordingly, as depicted, the bottom surface 1538 defines a first ramped feature 1552 on a first side of the second opening 1524.
- the first ramped feature 1552 has a crest surface or point 1554 spaced between two trough depressions 1556a and 1556b.
- a second ramped feature 1558 is positioned on a second side of the second opening 1524.
- the second ramped feature 1558 includes a crest surface or point 1560 spaced between two trough depressions 1562a and 1562b.
- the lid assembly 1500 additionally includes a recess pocket 1561 extending into an inner surface 1563 of the sidewall that extends below the bottom surface 1538 of the middle wall 1518. Accordingly, the recess pocket 1561 receives a portion of the lower sled 1536 when the slider mechanism 1502 is in the closed position depicted in FIG. 15 .
- the second opening 1524 may include detents 1548 that extend from the middle wall 1518 into the second opening 1524. These detents 1548 are configured to be received into channels 1550 (see FIG. 18B ) extending along a portion of the curved walls 1646a and 1646b of the lower sled 1536 when the slider mechanism 1502 is in the closed position depicted in FIG. 15 . Accordingly, the detents 1548 are configured to provide an interference fitting to prevent the slider mechanism 1502 from being inadvertently moved and thereby inadvertently unseal the first opening 1504. In one example, the slider mechanism 1502 may be configured to lock in the open and/or closed configuration. It is further contemplated that a locking mechanism in addition to the detents 1548 may be used to further prevent the slider mechanism 1502 from being inadvertently moved.
- FIGS. 18A and 18B depict isometric views of the lower sled 1536, according to one or more aspects described herein.
- the lower sled 1536 includes an inner surface 1564 that is configured to be positioned adjacent to the bottom surface 1538 of the middle wall 1518.
- the inner surface 1564 includes a lower sled ramp 1566.
- the lower sled ramp 1566 is configured to be received into one of the trough depressions of each of the first ramped feature 1552 and the second ramped feature 1558.
- the lower sled ramp 1566 is configured to slide across the first ramped feature 1552 and the second ramped feature 1558 as the slider mechanism 1502 slides between the open and closed configurations.
- the lower sled ramp 1566 will abut the crest surfaces 1554 and 1560. Further, because the crest surfaces 1554 and 1560 are raised relative to the trough depressions on either side of the crest surfaces 1554 and 1560, this will urge the upper sled 1530 and the lower sled 1536 to space further apart from one another. As such, because the magnetic force between the upper sled magnet and the lower sled magnet is inversely proportional to the square of the distance between them, the magnetic attractive force will be reduced when the lower sled ramp 1566 abuts the crest surfaces 1554 and 1560.
- this reduction in magnetic force will provide for smooth movement of the slider mechanism 1502 between the open and closed positions. Further, when the lower sled ramp 1566 is positioned within the trough depressions of the first ramped feature 1552 and the second ramped feature 1558, the comparatively shorter distance between the upper sled magnet and the lower sled magnet will result in a comparatively stronger magnetic attractive force that serves to secure the slider mechanism 1502 in the open or closed configuration.
- the lower sled 1536 includes a curved walls 1646a and 1646b that extend from the inner surface 1564 to tabs/ tab ears 1568a and 1568b.
- the tab ears 1568a and 1568b are configured to extend through the second opening 1524.
- the lower sled 1536 further includes a channel 1570 that is configured to receive a portion of the lower gasket 1544.
- the lower sled 1536 includes lower vent channels 1571a and 1571b. Accordingly, 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 and into an internal cavity of the container 1505.
- This air flow path may reduce or prevent glugging as liquid is poured from the first opening 1504. Further, the air flow path may be configured to relieve a pressure differential between an internal cavity of the container 1505 and an external environment. As such, an increased pressure within an internal cavity of the container 1505 may be partially or wholly relieved as a gas/ air is allowed to escape to an external environment surrounding the container 1505 through the slider mechanism 1502.
- the lower sled 1536 includes a knob air vent 1802 that extends from the seal surface 1650 through to a lower surface 1804 of the knob 1574.
- the knob air vent is configured to allow air to pass between an internal cavity of the container 1505 and an external environment surrounding the container 1505. In one example, air may pass through the knob air vent 1802, through the second opening 1524 and out to the external environment.
- the lower sled 1536 and the upper sled 1530 are positioned moved from the closed position depicted in FIG. 15 to the open position schematically depicted in FIG. 22 , the lower sled 1536 is spaced apart from the upper sled 1530.
- This spacing unseals the radial ridges 1664 from the seal surface 1640 and allows air to flow through the knob air vent 1802 between the internal cavity of the container 1505 and the external environment.
- This knob air vent 1802 may reduce or prevent glugging due to a relative pressure difference between the internal cavity of the container and the external environment as a liquid is being poured from the first opening 1504.
- the curved walls 1646a and 1656b may be separated by gaps 1648a and 1648b. These gaps 1648a and 1648b may allow air to escape when a portion of the upper sled 1530 is brought into contact with a seal surface 1650 of the lower sled 1536.
- the seal surface 1650 may have a smooth surface texture to enhance a seal between the upper sled 1530 and lower sled 1536.
- the seal surface 1650 may include a polished surface finish, and may be an SPI-A2 finish.
- a separation distance between a lower surface 1652a or 1652b of the tab ears 1568a and 1568b and the inner surface 1564 may be such that the lower sled 1536 cannot be inserted on the incorrect side of the slider mechanism 1502.
- the separation distance between a lower surface 1652a or 1652b of the tab ears 1568a and 1568b and the inner surface 1564 may be less than the wall thickness between top surface 1520 and bottom surface 1538. This geometry prevents the lower sled 1536 from being inserted into the second opening 1524 such that the inner surface 1564 would be in contract with the recess 1522.
- FIG. 19 depicts a configuration whereby the lower sled 1536 is on the incorrect top surface 1520 but cannot be fully inserted into the recess 1522.
- FIG. 18B depicts an isometric view of an outer surface 1572 of the lower sled 1536.
- a knob 1574 extends from the outer surface 1572. This knob 1574 is configured to be gripped by a user in order to install the slider mechanism 1502 in the lid assembly 1500.
- the knob 1574 may comprise a grip surface finish.
- the knob 1574, or a portion thereof, may be formed from a first material and the remainder of the lower sled 1536 may be formed from a second, different material.
- the knob 1574 may have a rubberized outer surface.
- the lower sled 1536 encapsulates a lower sled magnet, similar to lower magnet 142. In one example, this lower sled magnet of lower sled 1536 is encapsulated within the knob 1574.
- FIG. 20 depicts a view of an inner side 1582 of the upper sled 1530.
- the upper sled 1530 includes upper vent channels 1584a and 1584b.
- An air vent path between an external environment and an internal cavity of the container 1505 may be completed as the upper vent channels 1584a and 1584b allow air to pass from the external environment into the slider mechanism 1502.
- the upper sled recesses 1586a and 1586b are configured to receive a portion of the tab ears 1568a and 1568b of the lower sled 1536.
- a cylindrical spacer 1660 extends from the upper sled 1530 and is configured to be received between the curved walls 1646a and 1646b of the lower sled 1536.
- the cylindrical spacer 1660 includes a lower surface 1662 with radial ridges 1664. This lower surface 1662 and radial ridges 1664 are configured to abut seal surface 1650. In one example, the radial ridges 1664 form a seal with seal surface 1640 when the upper sled 1530 is magnetically coupled to the lower sled 1536 when the slider mechanism 1502 is in a closed configuration and/or open configuration.
- the radial ridges 1664 may be formed from a rubber material. In one example, the radial ridges 1664 may be formed from a thermoplastic vulcanizate (TPV) material.
- the upper sled 1530 encapsulates an upper sled magnet. In one example, this upper sled magnet may be similar to upper magnet 132. In one example, the upper sled magnet is encapsulated within the cylindrical spacer 1660.
- the slider mechanism may include the upper sled 1530 and lower sled 1536 such that movement of the upper sled 1530 urges the lower sled 1536 to move in a same direction.
- This synchronous movement may result from the cylindrical spacer 1660 of the upper sled 1530 abutting one or more surfaces of the curved walls 1646a and 1646b of the lower sled 1536.
- the synchronous movement of the upper sled 1530 and the lower sled 1536 may not utilize magnets to urge the upper sled 1530 toward the lower sled 1536.
- the upper sled 1530 and/or lower sled 1536 may be implemented without magnet elements such that there is no magnetic attractive force between the upper sled 1530 and lower sled 1536.
- FIGS. 21A and 21B depict an isometric and an elevation view of the lower gasket 1544, according to one or more aspects described herein.
- the lower gasket 1544 is configured to seal the first opening 1504 when the slider mechanism 1502 is in the closed configuration depicted in FIG. 15 .
- the lower gasket 1544 is configured to seal the second opening 1524.
- an inner surface 1588 of the lower gasket 1544 is configured to be positioned over the outer surface 1572 of the lower sled 1536.
- the opening 1590 in the lower gasket 1544 is configured to allow the knob 1574 of the lower sled 1536 to extend through.
- the lower gasket 1544 may be constructed from silicone.
- the lower gasket 1544 may be integrally molded with the bottom slider 1536. Accordingly, lower gasket 1544 may be molded from a same or a different material to the bottom slider 1536 using a single- or multi-stage (single-shot or multi-shot) molding process.
- the lower gasket 1544 may have a lip 1692 that extends farther out from the inner surface 1588 than the comparable spring feature 192 of lower gasket 144. Accordingly, the lip 1692 may provide enhanced sealing when the lower gasket 1544 is positioned on the bottom surface 1538 of the lid 1501.
- FIG. 22 schematically depicts the lid assembly 1500 in an open configuration.
- a back wall 1690 of the recess 1522 is configured to abut the upper sled 1530 when positioned in the open configuration of FIG. 22 .
- the lower sled ramp 1566 may be held on the crest surface 1554 (and 1560).
- the lower gasket 1544 may be spaced apart from the bottom surface 1538 such that air can flow between an internal cavity of the container 1505, through the lid assembly 1500 and out to an external environment, thereby preventing or limiting glugging during pouring.
- slider mechanism 1502 described in relation to lid assembly 1500 may be similar to slider mechanism 2002, since both elements are denoted with labels ending in "02."
- the features of lid assembly 2000 may include features labeled with the first two digits being “21” or “22” and the final two digits being the same as those described in relation to lid assembly 1500 that have the first two digits of "16" or “18" respectively. Because the features are similar, these features may be described in lesser detail or not described at all with respect to lid assembly 2000. Additional, alternative or distinguishing features of the elements of lid assembly 2000 over those of lid assemblies 100 and 1500 may be noted in the subsequent descriptions.
- FIGS. 23-34 depict the lid assembly 2000.
- the lid assembly 2000 generally includes a slider mechanism 2002 that is configured to move between a closed position (depicted in FIG. 23 ) and an open position to selectively close or open a first opening 2004 through which a liquid, stored in the container, is configured to flow.
- the lid assembly 2000 includes a sidewall 2006, which defines a groove 2008 for placement of a gasket 2010. Accordingly, the gasket 2010 may provide a seal between the lid assembly 2000 and the container.
- other sealing methods for sealing the lid assembly 2000 to the container are also contemplated.
- the lid assembly 2000 includes a rim 2012 for engaging an opening of the container.
- the rim 2012 includes a top wall 2014 and grip elements 2116 extending from the top wall 2014 to assist the user in removing the lid assembly 2000 from the container.
- the lid assembly 2000 includes a lid 2001 with a middle wall 2018 extending below a rim 2012.
- a top surface 2020 of the middle wall 2018 defines a recess 2022 for receiving the slider mechanism 2002.
- the recess 2022 can define a guide channel as the slider mechanism 2002 moves between the closed position depicted in FIG. 23 and an open position.
- the first opening 2004 for drinking or pouring liquid out of the container can also be formed in the recess 2022.
- the recess 2022 may also include a second opening 2024.
- the slider mechanism 2002 includes an upper sled 2030, which is configured to be positioned within the recess 2022 on the top surface 2020 of the middle wall 2018.
- the upper sled 2030 includes an upper magnet that is encapsulated therein.
- the upper magnet may be encapsulated within a cavity within the upper sled 2030, and may be overmolded with a polymeric overmold plug element. Additional or alternative encapsulation methods may be used to secure the upper magnet within the upper sled 2030, without departing from the scope of these disclosures.
- the slider mechanism 2002 includes a lower sled 2036 that is configured to be positioned adjacent to a bottom surface 2038 of the middle wall 2018 (depicted in FIG. 32 ). Accordingly, FIG. 36 depicts the bottom surface 2038 of the middle wall 2018.
- the lower sled 2036 includes a lower sled magnet that is encapsulated therein. In one example, the lower sled magnet may be encapsulated within a cavity in the lower sled 2036, and may be overmolded with a polymeric overmold plug element. Additionally, the slider mechanism 2002 may include a lower gasket 2044 that is configured to extend around a perimeter of the lower sled 2036.
- the lower sled 2036 is described in further detail in relation to FIGS. 38-40 .
- Magnetic attraction between the upper sled magnet and the lower sled magnet magnetically couples the upper sled 2030 to the lower sled 2036 across the middle wall 2018. Accordingly, manual actuation of the upper sled 2030 on the top surface 2020 of the middle wall 2018 results in sliding motion of both the upper sled 2030 and the lower sled 2036.
- the recess 2022 may include a tapered surface 2025 between the first opening 2004 and the second opening 2024.
- This tapered surface 2025 may provide that a first depth of the recess 2022 near and/or adjacent to the first opening 2004 may be greater than a second depth adjacent the second opening 2024.
- the tapered surface 2025 may extend to be on either or both sides of the first opening 2004.
- the tapered surface 2025 may extend on either side or both sides of a portion of the second opening 2024.
- the tapered surface 2025 may allow for a forward portion 2031 of the upper sled 2030 to tilt downward into the region above the tapered surface 2025 to start the actuation of the slider mechanism 2002 from a closed position to an open position as will be discussed in more detail below.
- An upper surface 2023 of recess 2022 may further include a pair of engaging members 2170.
- Each engaging member 2170 may include a first ramped surface 2172 and a second ramped surface 2174 arranged adjacent to each other.

- Each channel 2180 of the lower sled may include a rear channel engaging member 2182.
- each rear channel engaging member 2182 When the slider mechanism 2002 is in the closed position, each rear channel engaging member 2182 may be forward of the engaging members 2170 in the recess 2022, and when the slider mechanism 2002 is in the open position, each rear channel engaging member 2182 may be rearward of the engaging members 2170.
- the interaction between the engaging members 2170 and their respective receiving channels 2180 may help to guide the slider mechanism 2002 in its forward and rearward movement.
- the engaging members 2170 and the rear channel engaging members 2182 may contact each other and act as stops to limit or restrict movement of the slider mechanism 2002 to prevent accidental opening of the lid assembly 2000.
- the lid assembly 2000 depicts two engaging members 2170
- the lid 2001 may comprise a single engaging member 2170 that is substantially centered longitudinally within the recess 2022 and positioned rearward of the second opening 2024. This single engaging member 2170 may be received in a centrally located channel 2180 extending along the lower surface of the upper sled 2030.
- the first ramped surface 2172 may be arranged where a first angle between the upper surface 2023 and the first ramped surface 2172 (the first angle may be defined as the angle between the upper surface 2023 and the first ramped surface 2172 in a counterclockwise direction) may be greater than a second angle of the upper surface 2023 and the second ramped surface 2174 (the second angle may be defined as the angle between the upper surface 2023 and the second ramped surface 2174 in a clockwise direction).
- each rear channel engaging member 2182 may have a first ramped surface 2184 and a second ramped surface 2186 arranged adjacent to each other.
- the first ramped surfaces 2184 may be arranged where a first angle between a bottom channel surface 2185 and the first ramped surface 2184 (the first angle may be defined as the angle between the bottom channel surface 2185 and the first ramped surface 2184 in a counterclockwise direction, when upper sled 2030 has bottom channel surface 2185 facing upward) may be smaller than a second angle of the bottom channel surface 2185 to the second ramped surface 2186 (the second angle may be defined as the angle between the bottom channel surface 2185 and the second ramped surface 2186 in a clockwise direction, when upper sled 2030 has bottom channel surface 2185 facing upward).
- each second ramped surface 2174 of the each engaging member 2170 may face the first ramped surface 2184 of each rear channel engaging member 2182.
- each first ramped surface 2172 of each engaging member 2170 may face the second ramped surface 2186 of the rear channel engaging member 2182.
- Each channel 2180 may extend through a front surface 2190 of the upper sled 2030 and may also extend through a rear surface 2192 of the upper sled 2030. Each channel 2180 may be intermittent; such that is 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 spacer 2160 or may be interrupted by the cylindrical spacer 2160. In alternate examples, each channel 2180 may be continuous from the front surface 2190 to the rear surface 2192. Each channel 2180 may be spaced apart from and substantially parallel to each other. In addition, each channel 2180 may include a forward channel engaging member 2196. Each forward channel engaging member 2196 may have the same geometry and shape as each rear channel engaging member 2182.
- Each forward channel engaging member 2196 may be a mirror image of the rear channel engaging members 2182 with respect to a plane that extends perpendicular to the channels 2180 and through a center of the upper sled 2030. Because the channel engaging members 2182, 2196 are located as a mirror image, the upper sled 2030 may be assembled in multiple orientations.
- slider mechanism 2002 may also interact in a similar manner with lid 2001 as slider mechanism 1502 and lid 1501.
- lid 2001 may have a bottom surface 2038 of the middle wall 2018 that includes a first ramped feature 2052 on a first side of the second opening 2024 and a second ramped feature 2058 arranged on an opposite side of the second opening 2024.
- the first ramped feature 2052 has a crest surface or point 2054 spaced between two trough depressions 2056a and 2056b.
- the second ramped feature 2058 may include a crest surface or point 2060 spaced between two trough depressions 2062a and 2062b.
- FIGS. 33A-33F depict a process for a user to move the slider mechanism 2002 from a closed position shown in FIG. 33A to a fully open position shown in FIG. 33F .
- the first step in the process shown in FIG. 33B , depicts the slider mechanism 2002 being moved slightly rearward from the closed position when a user begins to exert a rearward force, but further travel is prevented by engaging member 2170.
- FIG. 33C a user may press downward on the forward portion 2031 of the upper sled 2030, which causes the rear portion 2033 to move upward.
- any gases or fluids that may be under pressure between the upper sled 2030, the lower sled 2036 and the container are vented outward from the rear of the upper sled 2030 away from where a user may place to his or her mouth to drink from the lid 2001.

FIG. 1 depicts an isometric view of alid assembly 100 that is removably coupled to acontainer 105, according to one or more aspects described herein.Container 105 is one example container to which thelid assembly 100 may be configured to be removably coupled. Accordingly, thecontainer 105 may be configured to store a volume of liquid and thelid assembly 100 may be configured to seal an opening of thecontainer 105. -
FIGS. 2A and 2B depict isometric views of thelid assembly 100 in a closed and an open configuration, respectively. Thelid assembly 100 generally includes aslider mechanism 102 that is configured to move between a closed position (depicted inFIG. 2A ) and an open position (depicted inFIG. 2B ) to selectively close or open afirst opening 104 through which a liquid, stored in thecontainer 105, is configured to flow. Further details of theslider mechanism 102 are discussed in relation to the proceeding figures. Thelid assembly 100 includes asidewall 106, which defines agroove 108 for placement of agasket 110. Accordingly, thegasket 110 may provide a seal between thelid assembly 100 and thecontainer 105. However, other sealing methods for sealing thelid assembly 100 to thecontainer 105 are also contemplated. Thelid assembly 100 includes arim 112 for engaging an opening of thecontainer 105. Therim 112 includes atop wall 114 andgrip elements 116 and/or an optional lid tab (not depicted) extending from thetop wall 114 to assist the user in removing thelid assembly 100 from thecontainer 105. - The
lid assembly 100 includes amiddle wall 118 extending below therim 112. Atop surface 120 of themiddle wall 118 defines arecess 122 for receiving theslider mechanism 102. In one example, therecess 122 can define a guide channel as theslider mechanism 102 moves between the closed position depicted inFIG. 2A and the open position depicted inFIG. 2B . As shown inFIG. 2B , thefirst opening 104 for drinking or pouring liquid out of the container is formed in therecess 122.
Therecess 122 includes asecond opening 124, which is described in further detail in relation toFIG. 5A . Adetent 126 may extend into from thetop surface 120 of themiddle wall 118 into therecess 122. Thisdetent 126 may be configured to abut theslider mechanism 102 when in the open position depicted inFIG. 2B to prevent liquid from being compressed between theslider mechanism 102 and anend wall 128 of therecess 122, which may otherwise result in splashing of a liquid that may pool in therecess 122 as a result of a user drinking or pouring from thefirst opening 104. -
FIG. 3 schematically depicts an exploded isometric view of thelid assembly 100, according to one or more aspects described herein. In particular,FIG. 3 schematically depicts multiple elements that make up theslider mechanism 102, as discussed in relation toFIGS. 2A and 2B . Accordingly, theslider mechanism 102 includes anupper sled 130, which is configured to be positioned within therecess 122 on thetop surface 120 of themiddle wall 118. Theupper sled 130 includes anupper magnet 132 that is encapsulated therein. In one example, theupper magnet 132 may be encapsulated within a cavity in theupper sled 130, and may be overmolded with a polymericovermold plug element 134. Additional or alternative encapsulation methods may be used to secure theupper magnet 132 within theupper sled 130, without departing from the scope of these disclosures. Additionally, theupper sled magnet 132 may be formed of any suitable ferromagnetic or otherwise magnetic material. Theupper sled 130 is discussed in further detail in relation toFIGS. 7A and 7B . - The
slider mechanism 102 additionally includes alower sled 136 that is configured to be positioned adjacent to abottom surface 138 of the middle wall 118 (depicted inFIG. 5B ). Thelower sled 136 includes alower sled magnet 140 that is encapsulated therein. In one example, thelower sled magnet 140 may be encapsulated within a cavity in thelower sled 136, and may be overmolded with a polymericovermold plug element 142. Additionally, theslider mechanism 102 may include alower gasket 144 that is configured to extend around a perimeter of thelower sled 136. Thelower sled 136 is described in further detail in relation toFIGS. 6A and 6B . - Magnetic attraction between the
upper sled magnet 132 and thelower sled magnet 140 magnetically couples theupper sled 130 to thelower sled 136 across themiddle wall 118. Accordingly, manual actuation of theupper sled 130 on the top surface 6 of themiddle wall 118 results in sliding motion of both theupper sled 130 and thelower sled 136. -
FIG. 4 schematically depicts a cross-sectional view through thelid assembly 100, according to one or more aspects described herein. As depicted, theslider mechanism 102 is in a closed configuration such that thefirst opening 104 is sealed by theslider mechanism 102. In one example, thelower sled magnet 140 may have a cylindrical geometry with a hollow center. As such, thelower sled magnet 140 may otherwise be described as a ring magnet that extends around acentral tube 146 through theovermolded plug element 142 and thelower sled 136. In another example, thelower sled magnet 140 may have a solid cylindrical geometry. -
FIGS. 5A and 5B depict isometric views of thelid assembly 100 without theslider mechanism 102. In particular,FIG. 5A depicts a view of thetop surface 120 of themiddle wall 118, andFIG. 5B depicts a view of thebottom surface 138 of themiddle wall 118. As depicted, thelid mechanism 100 includes afirst opening 104 and asecond opening 124. In one example, a portion of theslider mechanism 102 is configured to extend through thesecond opening 124 when theupper sled 130 is magnetically coupled to thelower sled 136. - The
second opening 124 may includedetents 148 that extend from themiddle wall 118 into thesecond opening 124. Thesedetents 148 are configured to be received into channels 150 (seeFIG. 6A ) extending along a portion of thecentral tube 146 of thelower sled 136 when theslider mechanism 102 is in the closed position depicted inFIG. 2A . Accordingly, thedetents 148 are configured to provide an interference fitting to prevent theslider mechanism 102 from being inadvertently moved and thereby inadvertently unseal thefirst opening 104. In one example, theslider mechanism 102 may be configured to lock in the open and/or closed configuration depicted inFIGS. 2A and 2B . It is further contemplated that a locking mechanism in addition to thedetents 148 may be used to further prevent theslider mechanism 102 from being inadvertently moved. -
FIG. 5B depicts thebottom surface 138 of themiddle wall 118. Accordingly, as depicted, thebottom surface 138 defines a first rampedfeature 152 on a first side of thesecond opening 124. The first rampedfeature 152 having acrest surface 154 spaced between twotrough depressions 156. Similarly, a second rampedfeature 158 is positioned on a second side of thesecond opening 124. The second rampedfeature 158 includes acrest surface 160 spaced between twotrough depressions 162. - The
lid assembly 100 additionally includes arecess pocket 161 extending into aninner surface 163 of the sidewall that extends below thebottom surface 138 of themiddle wall 118. Accordingly, therecess pocket 161 receives a portion of thelower sled 136 when theslider mechanism 102 is in the closed position depicted inFIG. 2A . Thelid assembly 100 also includes a recessedvent pocket 165, such that the geometry of the recessedvent pocket 165 allows air to flow into thecontainer 105 as a liquid is being poured out of thefirst opening 104. -
FIGS. 6A and 6B depict isometric views of thelower sled 136, according to one or more aspects described herein. Accordingly, thelower sled 136 includes aninner surface 164 that is configured to be positioned adjacent to thebottom surface 138 of themiddle wall 118. Theinner surface 164 includes alower sled ramp 166. Thelower sled ramp 166 is configured to be received into one of the trough depressions of each of the first rampedfeature 152 and the second rampedfeature 158. As such, thelower sled ramp 166 is configured to slide across the first rampedfeature 152 and the second rampedfeature 158 as theslider mechanism 102 slides between the open and close configurations. As theslider mechanism 102 transitions between the open and the closed configuration, thelower sled ramp 166 will abut the crest surfaces 154 and 160. Further, because the crest surfaces 154 and 160 are raised relative to the trough depressions on either side of the crest surfaces 154 and 160, this will urge theupper sled 130 and thelower sled 136 to space further apart from one another. As such, because the magnetic force between theupper sled magnet 132 and thelower sled magnet 140 is inversely proportional to the square of the distance between them, the magnetic attractive force will be reduced when thelower sled ramp 166 abuts the crest surfaces 154 and 160. In one example, this reduction in magnetic force will provide for smooth movement of theslider mechanism 102 between the open and closed positions. Further, when thelower sled ramp 166 is positioned within the trough depressions of the first rampedfeature 152 and the second rampedfeature 158, the comparatively shorter distance between theupper sled magnet 132 and thelower sled magnet 140 will result in a comparatively stronger magnetic attractive force that serves to secure theslider mechanism 102 in the open or closed configuration. - It is noted that the
lower sled 136 and theupper sled 130 are symmetrical about to perpendicular axes in order to allow the slider mechanism to be installed in thelid assembly 100 in any of four different ways. Thelower sled 136 additionally includes acentral tube 146 that extends from theinner surface 164. Further, thecentral tube 146 includestab ears 168 that are configured to extend through thesecond opening 124. Thelower sled 136 further includes achannel 170 that is configured to receive a portion of thelower gasket 144. Additionally, thelower sled 136 includeslower vent channels slider mechanism 102 is in the open configuration, a portion of thelower sled 136 extends over a portion of the recessedvent pocket 165. Further, one of thelower vent channels vent pocket 165, and thereby sets up a channel by which air can pass from theslider mechanism 102 into an internal cavity of thecontainer 105. -
FIG. 6B depicts an isometric view of anouter surface 172 of thelower sled 136. In one example, aknob 174, otherwise referred to asfinger tabs 174 extend from theouter surface 172. Thisknob 174 is configured to be gripped by a user in order to install theslider mechanism 102 in thelid assembly 100. This installation process is described in further detail in relation toFIG. 12 . -
FIGS. 7A and 7B depict isometric views of theupper sled 130. Theupper sled 130 can include twosymmetrical flanges first opening 104 for pouring liquid out of the container and thesecond opening 124 in therecess 122, otherwise referred to as aguide channel 122. The tab or thehandle 178 is configured for the user to grasp to selectively move theupper sled 130, and thereby theslider mechanism 102, into an opened position to uncover thefirst opening 104 on thelid assembly 100 or closed position to cover thefirst opening 104 on thelid assembly 100. The tab or handle 178 may include two inwardly taperedportions -
FIG. 7B depicts a view of aninner side 182 of theupper sled 130. Accordingly, theupper sled 130 includesupper vent channels slider mechanism 102 is in the open configuration, a vent path is partially formed by a portion of thelower sled 136 extending over a portion of the recessedvent pocket 165. Additionally, one of thelower vent channels vent pocket 165, and thereby sets up a channel through which air can pass from theslider mechanism 102 into an internal cavity of thecontainer 105. This vent path between an external environment and the internal cavity of thecontainer 105 is completed as theupper vent channels slider mechanism 102. Theupper sled recesses tab ears 168 of thelower sled 136. -
FIGS. 8A and 8B depict an isometric and a partial cross-sectional view of thelower gasket 144, according to one or more aspects described herein. Accordingly, thelower gasket 144 is configured to seal thefirst opening 104 when theslider mechanism 102 is in the closed configuration depicted inFIG. 2A . Additionally, thelower gasket 144 is configured to seal thesecond opening 124. In one example, aninner surface 188 of thelower gasket 144 is configured to be positioned over theouter surface 172 of thelower sled 136. Theopening 190 in thelower gasket 144 is configured to allow theknob 174 of thelower sled 136 to extend through. In one example, thelower gasket 144 may be constructed from silicone. However, additional or alternative polymeric materials may be used, without departing from the scope of these disclosures. - The cross-sectional view of
FIG. 8B indicates thespring feature 192 of thelower gasket 144. Accordingly, thespring feature 192 allows the seal formed by thegasket 144 to move and stay in contact with thebottom surface 138 of themiddle wall 118. Accordingly, when in the open or closed configurations, the comparatively high magnetic force urging thelower sled 136 toward thebottom surface 138 of themiddle wall 118 compresses thespring feature 192 of thelower gasket 144. Further, when thelower sled ramp 166 is positioned on the crest surfaces 154 and 160, and the magnetic force is comparatively lower and thelower sled 136 is moved away from thebottom surface 138, thespring feature 192 extends out toward and maintains contact with thebottom surface 138 to maintain the seal of thelower gasket 144 on thebottom surface 138. -
FIGS. 9A and 9B schematically depict cross-sectional views of thelid assembly 100 in a closed configuration. As depicted, theslider mechanism 102 that includes theupper sled 130 and thelower sled 136 is sealing thefirst opening 104.FIG. 9B depicts a more detailed view of a portion of the cross-section ofFIG. 9A . Accordingly,FIG. 9B depicts a portion of thelower sled 136 and thelower gasket 144 received into therecess pocket 161 of thelid assembly 100. -
FIGS. 10A and 10B schematically depict cross-sectional views of thelid assembly 100 in an open configuration. As depicted, thefirst opening 104 is completely uncovered by theslider mechanism 102 that includes theupper sled 130 and thelower side 136.FIG. 10B schematically depicts a more detailed view of a portion of the cross-section ofFIG. 10A . In particular,FIG. 10B depicts a portion of thelower gasket 144 that has been slid over a portion of the recessedvent pocket 165. The overlap of the portion of thelower gasket 144 on the portion of the recessedvent pocket 165 results in agap 192 through which the air can enter into thecontainer 105 as liquid is being poured from thefirst opening 104. -
FIGS. 11A and 11B schematically depict cross-sectional views of thelid assembly 100 in a partially-open configuration. As depicted, thefirst opening 104 is partially uncovered by theslider mechanism 102 that includes theupper sled 130 and thelower sled 136.FIG. 11B schematically depicts a more detailed view of a portion of the cross-section ofFIG. 11A . In particular,FIG. 11B depicts aseparation 196, orgap 196 between theupper sled 130 and thelower sled 136. Thisseparation 196 results from thelower sled ramp 166 abutting the crest surfaces 154 and 160, as previously described. -
FIGS. 12A-12D depict various steps for disassembly of theslider mechanism 102 and removal from thelid assembly 100. As previously described, theslider mechanism 102 includes theupper sled 130 and thelower sled 136. Further, the upper sled includes theupper sled magnet 132, and thelower sled 136 includes thelower sled magnet 140 andlower gasket 144.FIG. 12A depicts thelid assembly 100 with theslider mechanism 102 fully installed and in an open configuration. In order to remove the slider mechanism, for example to facilitate cleaning of thelid assembly 100, theupper sled 130 may be manually lifted from thetop surface 120.FIG. 12B depicts theupper sled 130 after having being removed from thetop surface 120. Once theupper sled 130 is removed, thelower sled 136 is no longer held against thebottom surface 138 by the magnetic attractive force between theupper sled magnet 132 and thelower sled magnet 140. However,tab ears 168 prevent thelower sled 136 from falling into thecontainer 105 as thetab ears 168 extend through thesecond opening 124 and grip onto a portion of thetop surface 120. - In order to remove the
lower sled 136 from thelid assembly 100, thelower sled 136 is rotated through 90° such that thetab ears 168 can be passed through thesecond opening 124.FIG. 12D depicts theupper sled 130 andlower sled 136 fully removed from thelid assembly 100. -
FIG. 13 schematically depicts a cross-sectional view of a portion of thelid assembly 100 coupled to acontainer 105. In one example, thelid assembly 100 may be resealably coupled to thecontainer 105 by threaded elements on both thesidewall 106 of thelid assembly 100, and asidewall 202 of thecontainer 105.Elements sidewalls lid assembly 100 to thecontainer 105, without departing from the scope of these disclosures. Alternatively, thevarious lid assembly 100 structures described throughout this disclosure may be implemented without a threaded coupling between thelid assembly 100 and thecontainer 105. In one example, thelid assembly 100 may be secured to thecontainer 105 by an interference fit, among others. -
FIGS. 14A-14E depict an alternative implementation of a slider mechanism that has an alternative disassembly mechanism. Accordingly,FIG. 14A depicts an isometric view of alid assembly 300 that includes aslider mechanism 301. Thelid assembly 300 may be similar tolid assembly 100, and theslider mechanism 301 may be similar toslider mechanism 102. Theslider mechanism 301 may include anupper sled 302 similar toupper sled 130, and alower sled 306 similar tolower sled 136. In order to disassemble the slider mechanism, theupper sled 302 may be manually removed from thelid assembly 300. Similar to thelower sled 136, thelower sled 306 may includetab ears 308 to prevent thelower sled 306 from falling into the container when theupper sled 302 is removed. However, in order to remove thelower sled 306 from thelid assembly 300, thelower sled 306 is slid to the position depicted inFIG. 14C , such that the geometry of thetab ears 308 aligns with the geometry of anopening 309 in themiddle wall 310 of thelid assembly 300. When positioned in the configuration depicted inFIG. 14C , thelower sled 306 can pass through theopening 309, as depicted inFIG. 14D. FIG. 14E depicts theupper sled 302 andlower sled 306 fully removed from thelid assembly 300. -
FIG. 15 depicts another implementation of alid assembly 1500 that is configured to be removably coupled to acontainer 1505, according to one or more aspects described here. Thelid assembly 1500 andcontainer 1505 may be interchangeable withlid assembly 100 andcontainer 105, such thatlid assembly 1500 may be removably coupled tocontainer 105 andlid assembly 100 may be removably coupled tocontainer 1505. Thelid assembly 1500 may include multiple elements similar tolid assembly 100, such that reference numerals used to described features oflid assembly 1500 may include elements of similar features described in relation tolid assembly 100, if those features are labelled with the first two digits being "15" and the final two digits being the same as those described in relation tolid assembly 100. For example,slider mechanism 102 described in relation tolid assembly 100 may be similar toslider mechanism 1502, since both elements are denoted with labels ending in "02." Additional, alternative or distinguishing features of the elements oflid assembly 1500 over those oflid assembly 100 may be noted in the proceeding descriptions. -
FIG. 16 schematically depicts an exploded view of multiple elements of thelid assembly 1500, according to one or more aspects described herein. Thelid assembly 1500 generally includes aslider mechanism 1502 that is configured to move between a closed position (depicted inFIG. 15 ) and an open position to selectively close or open afirst opening 1504 through which a liquid, stored in thecontainer 1505, is configured to flow. Thelid assembly 1500 includes asidewall 1506, which defines agroove 1508 for placement of agasket 1510. Accordingly, thegasket 1510 may provide a seal between thelid assembly 1500 and thecontainer 1505. However, other sealing methods for sealing thelid assembly 1500 to thecontainer 1505 are also contemplated. Thelid assembly 1500 includes arim 1512 for engaging an opening of thecontainer 1505. Therim 1512 includes atop wall 1514 andgrip elements 1616 extending from thetop wall 1514 to assist the user in removing thelid assembly 1500 from thecontainer 1505. As depicted, thegrip elements 1616 include multiple groove elements extending along avertical wall 1602 of therim 1512. It is contemplated that thesegrip elements 1616 may have any groove geometries (depth, spacing, among others) and may be made from a same material or a different material to therim 1512 element. Additionally or alternatively, the grip elements may include different grip surface geometries to the depicted grooves, such as dimples, protrusions, or a relatively smooth grip surface. - The
lid assembly 1500 includes alid 1501 with amiddle wall 1518 extending below arim 1512. Atop surface 1520 of themiddle wall 1518 defines arecess 1522 for receiving theslider mechanism 1502. In one example, therecess 1522 can define a guide channel as theslider mechanism 1502 moves between the closed position depicted inFIG. 15 and an open position. Thefirst opening 1504 for drinking or pouring liquid out of the container is formed in therecess 1522. Therecess 1522 also includes asecond opening 1524. Adetent 1526 may extend from thetop surface 1520 of themiddle wall 1518 into therecess 1522. Thisdetent 1526 may be configured to abut theslider mechanism 1502 when in the open position to prevent liquid from being compressed between theslider mechanism 1502 and an end wall 1528 of therecess 1522, which may otherwise result in splashing of a liquid that may pool in therecess 1522 as a result of a user drinking or pouring from thefirst opening 1504. - The
slider mechanism 1502 includes anupper sled 1530, which is configured to be positioned within therecess 1522 on thetop surface 1520 of themiddle wall 118. Theupper sled 1530 includes an upper magnet that is encapsulated therein. In one example, the upper magnet may be encapsulated within a cavity within theupper sled 1530, and may be overmolded with a polymeric overmold plug element. Additional or alternative encapsulation methods may be used to secure the upper magnet within theupper sled 1530, without departing from the scope of these disclosures. - The
slider mechanism 1502 includes alower sled 1536 that is configured to be positioned adjacent to abottom surface 1538 of the middle wall 1518 (depicted inFIG. 17 ). Accordingly,FIG. 17 depicts thebottom surface 1538 of themiddle wall 1518. Thelower sled 1536 includes a lower sled magnet that is encapsulated therein. In one example, the lower sled magnet may be encapsulated within a cavity in the lower sled, and may be overmolded with a polymeric overmold plug element. Additionally, theslider mechanism 1502 may include alower gasket 1544 that is configured to extend around a perimeter of thelower sled 1536. Thelower sled 1536 is described in further detail in relation toFIGS. 18A and 18B Magnetic attraction between the upper sled magnet and the lower sled magnet magnetically couples theupper sled 1530 to thelower sled 1536 across themiddle wall 1518. Accordingly, manual actuation of theupper sled 1530 on thetop surface 1520 of themiddle wall 1518 results in sliding motion of both theupper sled 1530 and thelower sled 1536. -
FIG. 17 depicts a bottom view of thelid assembly 1500, according to one or more aspects described herein.FIG. 17 depicts thebottom surface 1538 of themiddle wall 1518. Accordingly, as depicted, thebottom surface 1538 defines a first rampedfeature 1552 on a first side of thesecond opening 1524. The first rampedfeature 1552 has a crest surface orpoint 1554 spaced between twotrough depressions feature 1558 is positioned on a second side of thesecond opening 1524. The second rampedfeature 1558 includes a crest surface orpoint 1560 spaced between twotrough depressions - The
lid assembly 1500 additionally includes arecess pocket 1561 extending into aninner surface 1563 of the sidewall that extends below thebottom surface 1538 of themiddle wall 1518. Accordingly, therecess pocket 1561 receives a portion of thelower sled 1536 when theslider mechanism 1502 is in the closed position depicted inFIG. 15 . - The
second opening 1524 may includedetents 1548 that extend from themiddle wall 1518 into thesecond opening 1524. Thesedetents 1548 are configured to be received into channels 1550 (seeFIG. 18B ) extending along a portion of thecurved walls lower sled 1536 when theslider mechanism 1502 is in the closed position depicted inFIG. 15 . Accordingly, thedetents 1548 are configured to provide an interference fitting to prevent theslider mechanism 1502 from being inadvertently moved and thereby inadvertently unseal thefirst opening 1504. In one example, theslider mechanism 1502 may be configured to lock in the open and/or closed configuration. It is further contemplated that a locking mechanism in addition to thedetents 1548 may be used to further prevent theslider mechanism 1502 from being inadvertently moved. -
FIGS. 18A and 18B depict isometric views of thelower sled 1536, according to one or more aspects described herein. Thelower sled 1536 includes aninner surface 1564 that is configured to be positioned adjacent to thebottom surface 1538 of themiddle wall 1518. Theinner surface 1564 includes alower sled ramp 1566. Thelower sled ramp 1566 is configured to be received into one of the trough depressions of each of the first rampedfeature 1552 and the second rampedfeature 1558. As such, thelower sled ramp 1566 is configured to slide across the first rampedfeature 1552 and the second rampedfeature 1558 as theslider mechanism 1502 slides between the open and closed configurations. As theslider mechanism 1502 transitions between the open and the closed configuration, thelower sled ramp 1566 will abut the crest surfaces 1554 and 1560. Further, because the crest surfaces 1554 and 1560 are raised relative to the trough depressions on either side of the crest surfaces 1554 and 1560, this will urge theupper sled 1530 and thelower sled 1536 to space further apart from one another. As such, because the magnetic force between the upper sled magnet and the lower sled magnet is inversely proportional to the square of the distance between them, the magnetic attractive force will be reduced when thelower sled ramp 1566 abuts the crest surfaces 1554 and 1560. In one example, this reduction in magnetic force will provide for smooth movement of theslider mechanism 1502 between the open and closed positions. Further, when thelower sled ramp 1566 is positioned within the trough depressions of the first rampedfeature 1552 and the second rampedfeature 1558, the comparatively shorter distance between the upper sled magnet and the lower sled magnet will result in a comparatively stronger magnetic attractive force that serves to secure theslider mechanism 1502 in the open or closed configuration. - The
lower sled 1536 includes acurved walls inner surface 1564 to tabs/tab ears tab ears second opening 1524. Thelower sled 1536 further includes achannel 1570 that is configured to receive a portion of thelower gasket 1544. Additionally, thelower sled 1536 includeslower vent channels slider mechanism 1502 is in the open configuration, one or more of thelower vent channels slider mechanism 1502 and into an internal cavity of thecontainer 1505. This air flow path may reduce or prevent glugging as liquid is poured from thefirst opening 1504. Further, the air flow path may be configured to relieve a pressure differential between an internal cavity of thecontainer 1505 and an external environment. As such, an increased pressure within an internal cavity of thecontainer 1505 may be partially or wholly relieved as a gas/ air is allowed to escape to an external environment surrounding thecontainer 1505 through theslider mechanism 1502. - Additionally, the
lower sled 1536 includes aknob air vent 1802 that extends from theseal surface 1650 through to alower surface 1804 of theknob 1574. The knob air vent is configured to allow air to pass between an internal cavity of thecontainer 1505 and an external environment surrounding thecontainer 1505. In one example, air may pass through theknob air vent 1802, through thesecond opening 1524 and out to the external environment. In one example, when thelower sled 1536 and theupper sled 1530 are positioned moved from the closed position depicted inFIG. 15 to the open position schematically depicted inFIG. 22 , thelower sled 1536 is spaced apart from theupper sled 1530. This spacing unseals theradial ridges 1664 from the seal surface 1640 and allows air to flow through theknob air vent 1802 between the internal cavity of thecontainer 1505 and the external environment. Thisknob air vent 1802 may reduce or prevent glugging due to a relative pressure difference between the internal cavity of the container and the external environment as a liquid is being poured from thefirst opening 1504. - In one example, the
curved walls 1646a and 1656b may be separated bygaps gaps upper sled 1530 is brought into contact with aseal surface 1650 of thelower sled 1536. In one example, theseal surface 1650 may have a smooth surface texture to enhance a seal between theupper sled 1530 andlower sled 1536. In one example, theseal surface 1650 may include a polished surface finish, and may be an SPI-A2 finish. - In one example, a separation distance between a
lower surface tab ears inner surface 1564 may be such that thelower sled 1536 cannot be inserted on the incorrect side of theslider mechanism 1502. Specifically, the separation distance between alower surface tab ears inner surface 1564 may be less than the wall thickness betweentop surface 1520 andbottom surface 1538. This geometry prevents thelower sled 1536 from being inserted into thesecond opening 1524 such that theinner surface 1564 would be in contract with therecess 1522.FIG. 19 depicts a configuration whereby thelower sled 1536 is on the incorrecttop surface 1520 but cannot be fully inserted into therecess 1522. -
FIG. 18B depicts an isometric view of anouter surface 1572 of thelower sled 1536. In one example, aknob 1574 extends from theouter surface 1572. Thisknob 1574 is configured to be gripped by a user in order to install theslider mechanism 1502 in thelid assembly 1500. Theknob 1574 may comprise a grip surface finish. In one example, theknob 1574, or a portion thereof, may be formed from a first material and the remainder of thelower sled 1536 may be formed from a second, different material. In one example, theknob 1574 may have a rubberized outer surface. Thelower sled 1536 encapsulates a lower sled magnet, similar tolower magnet 142. In one example, this lower sled magnet oflower sled 1536 is encapsulated within theknob 1574. -
FIG. 20 depicts a view of aninner side 1582 of theupper sled 1530. Theupper sled 1530 includesupper vent channels 1584a and 1584b. An air vent path between an external environment and an internal cavity of thecontainer 1505 may be completed as theupper vent channels 1584a and 1584b allow air to pass from the external environment into theslider mechanism 1502. Theupper sled recesses tab ears lower sled 1536. Acylindrical spacer 1660 extends from theupper sled 1530 and is configured to be received between thecurved walls lower sled 1536. Thecylindrical spacer 1660 includes alower surface 1662 withradial ridges 1664. Thislower surface 1662 andradial ridges 1664 are configured toabut seal surface 1650. In one example, theradial ridges 1664 form a seal with seal surface 1640 when theupper sled 1530 is magnetically coupled to thelower sled 1536 when theslider mechanism 1502 is in a closed configuration and/or open configuration. Theradial ridges 1664 may be formed from a rubber material. In one example, theradial ridges 1664 may be formed from a thermoplastic vulcanizate (TPV) material. Theupper sled 1530 encapsulates an upper sled magnet. In one example, this upper sled magnet may be similar toupper magnet 132. In one example, the upper sled magnet is encapsulated within thecylindrical spacer 1660. - In one implementation, the slider mechanism may include the
upper sled 1530 andlower sled 1536 such that movement of theupper sled 1530 urges thelower sled 1536 to move in a same direction. This synchronous movement may result from thecylindrical spacer 1660 of theupper sled 1530 abutting one or more surfaces of thecurved walls lower sled 1536. In one example, the synchronous movement of theupper sled 1530 and thelower sled 1536 may not utilize magnets to urge theupper sled 1530 toward thelower sled 1536. In this example theupper sled 1530 and/orlower sled 1536 may be implemented without magnet elements such that there is no magnetic attractive force between theupper sled 1530 andlower sled 1536. -
FIGS. 21A and 21B depict an isometric and an elevation view of thelower gasket 1544, according to one or more aspects described herein. Accordingly, thelower gasket 1544 is configured to seal thefirst opening 1504 when theslider mechanism 1502 is in the closed configuration depicted inFIG. 15 . Additionally, thelower gasket 1544 is configured to seal thesecond opening 1524. In one example, aninner surface 1588 of thelower gasket 1544 is configured to be positioned over theouter surface 1572 of thelower sled 1536. Theopening 1590 in thelower gasket 1544 is configured to allow theknob 1574 of thelower sled 1536 to extend through. In one example, thelower gasket 1544 may be constructed from silicone. However, additional or alternative polymeric materials may be used, without departing from the scope of these disclosures. In one example, thelower gasket 1544 may be integrally molded with thebottom slider 1536. Accordingly,lower gasket 1544 may be molded from a same or a different material to thebottom slider 1536 using a single- or multi-stage (single-shot or multi-shot) molding process. - In one example, and as depicted in the elevation view of 21B, the
lower gasket 1544 may have alip 1692 that extends farther out from theinner surface 1588 than thecomparable spring feature 192 oflower gasket 144. Accordingly, thelip 1692 may provide enhanced sealing when thelower gasket 1544 is positioned on thebottom surface 1538 of thelid 1501. -
FIG. 22 schematically depicts thelid assembly 1500 in an open configuration. In one example, aback wall 1690 of therecess 1522 is configured to abut theupper sled 1530 when positioned in the open configuration ofFIG. 22 . Accordingly, when in the depicted open configuration, thelower sled ramp 1566 may be held on the crest surface 1554 (and 1560). In this configuration, thelower gasket 1544 may be spaced apart from thebottom surface 1538 such that air can flow between an internal cavity of thecontainer 1505, through thelid assembly 1500 and out to an external environment, thereby preventing or limiting glugging during pouring. -
FIGS. 23-40 depict another implementation of alid assembly 2000 that is configured to be removably coupled to acontainer 1505, according to one or more aspects described here. Thelid assembly 2000 may be interchangeable withlid assembly 1500 orlid assembly 100 such thatlid assembly 2000 may be removably coupled tocontainer 105,container 1505, or other similar container. Thelid assembly 2000 may include multiple elements similar tolid assembly 100 andlid assembly 1500, such that reference numerals used to described features oflid assembly 2000 may include elements of similar features described in relation tolid assemblies lid assemblies slider mechanism 1502 described in relation tolid assembly 1500 may be similar to slider mechanism 2002, since both elements are denoted with labels ending in "02." In addition, the features oflid assembly 2000 may include features labeled with the first two digits being "21" or "22" and the final two digits being the same as those described in relation tolid assembly 1500 that have the first two digits of "16" or "18" respectively. Because the features are similar, these features may be described in lesser detail or not described at all with respect tolid assembly 2000. Additional, alternative or distinguishing features of the elements oflid assembly 2000 over those oflid assemblies -
FIGS. 23-34 depict thelid assembly 2000. Thelid assembly 2000 generally includes a slider mechanism 2002 that is configured to move between a closed position (depicted inFIG. 23 ) and an open position to selectively close or open afirst opening 2004 through which a liquid, stored in the container, is configured to flow. Thelid assembly 2000 includes asidewall 2006, which defines agroove 2008 for placement of agasket 2010. Accordingly, thegasket 2010 may provide a seal between thelid assembly 2000 and the container. However, other sealing methods for sealing thelid assembly 2000 to the container are also contemplated. Thelid assembly 2000 includes arim 2012 for engaging an opening of the container. Therim 2012 includes atop wall 2014 andgrip elements 2116 extending from thetop wall 2014 to assist the user in removing thelid assembly 2000 from the container. - The
lid assembly 2000 includes alid 2001 with amiddle wall 2018 extending below arim 2012. Atop surface 2020 of themiddle wall 2018 defines arecess 2022 for receiving the slider mechanism 2002. In one example, therecess 2022 can define a guide channel as the slider mechanism 2002 moves between the closed position depicted inFIG. 23 and an open position. Thefirst opening 2004 for drinking or pouring liquid out of the container can also be formed in therecess 2022. Therecess 2022 may also include asecond opening 2024. - The slider mechanism 2002 includes an
upper sled 2030, which is configured to be positioned within therecess 2022 on thetop surface 2020 of themiddle wall 2018. Theupper sled 2030 includes an upper magnet that is encapsulated therein. In one example, the upper magnet may be encapsulated within a cavity within theupper sled 2030, and may be overmolded with a polymeric overmold plug element. Additional or alternative encapsulation methods may be used to secure the upper magnet within theupper sled 2030, without departing from the scope of these disclosures. - The slider mechanism 2002 includes a
lower sled 2036 that is configured to be positioned adjacent to abottom surface 2038 of the middle wall 2018 (depicted inFIG. 32 ). Accordingly,FIG. 36 depicts thebottom surface 2038 of themiddle wall 2018. Thelower sled 2036 includes a lower sled magnet that is encapsulated therein. In one example, the lower sled magnet may be encapsulated within a cavity in thelower sled 2036, and may be overmolded with a polymeric overmold plug element. Additionally, the slider mechanism 2002 may include alower gasket 2044 that is configured to extend around a perimeter of thelower sled 2036. Thelower sled 2036 is described in further detail in relation toFIGS. 38-40 . Magnetic attraction between the upper sled magnet and the lower sled magnet magnetically couples theupper sled 2030 to thelower sled 2036 across themiddle wall 2018. Accordingly, manual actuation of theupper sled 2030 on thetop surface 2020 of themiddle wall 2018 results in sliding motion of both theupper sled 2030 and thelower sled 2036. - As best shown in
FIG. 35 , therecess 2022 may include atapered surface 2025 between thefirst opening 2004 and thesecond opening 2024. Thistapered surface 2025 may provide that a first depth of therecess 2022 near and/or adjacent to thefirst opening 2004 may be greater than a second depth adjacent thesecond opening 2024. The taperedsurface 2025 may extend to be on either or both sides of thefirst opening 2004. In addition, the taperedsurface 2025 may extend on either side or both sides of a portion of thesecond opening 2024. The taperedsurface 2025 may allow for aforward portion 2031 of theupper sled 2030 to tilt downward into the region above the taperedsurface 2025 to start the actuation of the slider mechanism 2002 from a closed position to an open position as will be discussed in more detail below. - An
upper surface 2023 ofrecess 2022 may further include a pair of engagingmembers 2170. Each engagingmember 2170 may include a first rampedsurface 2172 and a second rampedsurface 2174 arranged adjacent to each other. The pair of engagingmembers 2170 may be spaced apart from each other and also arranged substantially parallel to each other. In addition, a majority of each engagingmember 2170 may be positioned rearward of thesecond opening 2024. In some examples, the entirety of each engagingmember 2170 may be positioned rearward of thesecond opening 2024. Each engagingmember 2170 may be individually received withinrespective channels 2180 that may be arranged along a lower surface of theupper sled 2030. Eachchannel 2180 of the lower sled may include a rearchannel engaging member 2182. When the slider mechanism 2002 is in the closed position, each rearchannel engaging member 2182 may be forward of the engagingmembers 2170 in therecess 2022, and when the slider mechanism 2002 is in the open position, each rearchannel engaging member 2182 may be rearward of the engagingmembers 2170. The interaction between the engagingmembers 2170 and theirrespective receiving channels 2180 may help to guide the slider mechanism 2002 in its forward and rearward movement. In addition, the engagingmembers 2170 and the rearchannel engaging members 2182 may contact each other and act as stops to limit or restrict movement of the slider mechanism 2002 to prevent accidental opening of thelid assembly 2000. While the illustratedlid assembly 2000 depicts twoengaging members 2170, thelid 2001 may comprise a single engagingmember 2170 that is substantially centered longitudinally within therecess 2022 and positioned rearward of thesecond opening 2024. This single engagingmember 2170 may be received in a centrally locatedchannel 2180 extending along the lower surface of theupper sled 2030. - Additionally, for each engaging
member 2170, the first rampedsurface 2172 may be arranged where a first angle between theupper surface 2023 and the first ramped surface 2172 (the first angle may be defined as the angle between theupper surface 2023 and the first rampedsurface 2172 in a counterclockwise direction) may be greater than a second angle of theupper surface 2023 and the second ramped surface 2174 (the second angle may be defined as the angle between theupper surface 2023 and the second rampedsurface 2174 in a clockwise direction). Similarly, each rearchannel engaging member 2182 may have a first rampedsurface 2184 and a second rampedsurface 2186 arranged adjacent to each other. The first rampedsurfaces 2184 may be arranged where a first angle between abottom channel surface 2185 and the first ramped surface 2184 (the first angle may be defined as the angle between thebottom channel surface 2185 and the first rampedsurface 2184 in a counterclockwise direction, whenupper sled 2030 hasbottom channel surface 2185 facing upward) may be smaller than a second angle of thebottom channel surface 2185 to the second ramped surface 2186 (the second angle may be defined as the angle between thebottom channel surface 2185 and the second rampedsurface 2186 in a clockwise direction, whenupper sled 2030 hasbottom channel surface 2185 facing upward). When the slider mechanism 2002 is in the closed position, each second rampedsurface 2174 of the each engagingmember 2170 may face the first rampedsurface 2184 of each rearchannel engaging member 2182. When the slider mechanism 2002 is in the open position, each first rampedsurface 2172 of each engagingmember 2170 may face the second rampedsurface 2186 of the rearchannel engaging member 2182. - Each
channel 2180 may extend through afront surface 2190 of theupper sled 2030 and may also extend through arear surface 2192 of theupper sled 2030. Eachchannel 2180 may be intermittent; such that is does not extend continuously from thefront surface 2190 to therear surface 2192. Eachchannel 2180 may be arranged on either side of thecylindrical spacer 2160 or may be interrupted by thecylindrical spacer 2160. In alternate examples, eachchannel 2180 may be continuous from thefront surface 2190 to therear surface 2192. Eachchannel 2180 may be spaced apart from and substantially parallel to each other. In addition, eachchannel 2180 may include a forwardchannel engaging member 2196. Each forwardchannel engaging member 2196 may have the same geometry and shape as each rearchannel engaging member 2182. Each forwardchannel engaging member 2196 may be a mirror image of the rearchannel engaging members 2182 with respect to a plane that extends perpendicular to thechannels 2180 and through a center of theupper sled 2030. Because thechannel engaging members upper sled 2030 may be assembled in multiple orientations. - In addition to the interaction of the
channels 2180 and engagingmembers 2170, slider mechanism 2002 may also interact in a similar manner withlid 2001 asslider mechanism 1502 andlid 1501. For instance, as shown inFIG. 36 ,lid 2001 may have abottom surface 2038 of themiddle wall 2018 that includes a first rampedfeature 2052 on a first side of thesecond opening 2024 and a second rampedfeature 2058 arranged on an opposite side of thesecond opening 2024. The first rampedfeature 2052 has a crest surface orpoint 2054 spaced between twotrough depressions feature 2058 may include a crest surface orpoint 2060 spaced between twotrough depressions 2062a and 2062b. -
FIGS. 33A-33F depict a process for a user to move the slider mechanism 2002 from a closed position shown inFIG. 33A to a fully open position shown inFIG. 33F . The first step in the process, shown inFIG. 33B , depicts the slider mechanism 2002 being moved slightly rearward from the closed position when a user begins to exert a rearward force, but further travel is prevented by engagingmember 2170. Next, inFIG. 33C , a user may press downward on theforward portion 2031 of theupper sled 2030, which causes therear portion 2033 to move upward. As therear portion 2033 moves upward, any gases or fluids that may be under pressure between theupper sled 2030, thelower sled 2036 and the container are vented outward from the rear of theupper sled 2030 away from where a user may place to his or her mouth to drink from thelid 2001. For instance, as theupper sled 2030 tilts, the sealingsurface 2150 of the lower sled may release from theradial ridges 2164 of thelower surface 2162 of theupper sled 2030 causing the release of any pressurized gas or liquid within the container. Next, as shown inFIG. 33D and 33E , as the user exerts a rearward force on the slider mechanism 2002, the first rampedsurface 2184 of the rearchannel engaging member 2182 may slide along the second rampedsurface 2174 of engagingmember 2170 allowing the rearchannel engaging member 2182 to slide over and then move beyond engagingmember 2170. At the same time, thelower ramp sled 2066 of thelower sled 2036 begins moving from thefirst trough depression 2056a towards thesecond trough depression 2056b. The last step in the opening process shown inFIG. 33F , the user may continue exerting a rearward force until thelower ramp sled 2066 engages thesecond trough depression 2056b and/or therear surface 2192 of theupper sled 2030 contacts a stop surface of therecess 2022. Thelid assembly 2000 is now in an open position and ready to allow fluid to flow throughopening 2004. To move the slider mechanism 2002 back to the closed position, a user may exert a forward force on theupper sled 2030. The second rampedsurface 2184 slides up and over the first rampedsurface 2172 as shown inFIG. 34 . Theupper sled 2030 is then moved to cover thefirst opening 2004 to move the slider mechanism 2002 into the closed position as shown inFIG. 33A . -
FIG. 37 depicts a view theupper sled 2030. Theupper sled 2030 may includeupper vent channels upper vent channels upper sled recesses tab ears lower sled 2036. Acylindrical spacer 2160 extends from theupper sled 2030 and is configured to be received between the curved walls 2046a and 2046b of thelower sled 2036. Thecylindrical spacer 2160 includes alower surface 2162 withradial ridges 2164. Thislower surface 2162 andradial ridges 2164 are configured toabut seal surface 2150 of thelower sled 2036. In one example, theradial ridges 2164 form a seal withseal surface 2150 when theupper sled 2030 is magnetically coupled to thelower sled 2036 when the slider mechanism 2002 is in a closed configuration and/or open configuration. Theradial ridges 2164 may be formed from a compliant material such as a rubber based material. In one example, theradial ridges 2164 may be formed from a thermoplastic vulcanizate (TPV) material. Theupper sled 2030 encapsulates an upper sled magnet. In one example, this upper sled magnet may be similar toupper magnet 132. In one example, the upper sled magnet is encapsulated within thecylindrical spacer 2160. -
FIGS. 38-40 depict thelower sled 2036. Thelower sled 2036 may include aninner surface 2064 that is configured to be positioned adjacent to thebottom surface 2038 of themiddle wall 2018. Thelower sled 2036 may have features similar tolower sled 1536 such as alower ramp sled 2066 that interacts is configured to be received into one of the trough depressions of each of the first rampedfeature 2052 and the second rampedfeature 2058. As such, thelower ramp sled 2066 is configured to slide across the first rampedfeature 2052 and the second rampedfeature 2058 as the slider mechanism 2002 slides between the open and closed configurations. In addition, thelower sled 2036 may also includecurved walls inner surface 2064 to tabs/tab ears tab ears second opening 2024. Thelower sled 2036 further includes achannel 2070 that is configured to receive a portion of thelower gasket 2044. Additionally, thelower sled 2036 may includelower vent channels first opening 2004. Further, the air flow path may be configured to relieve a pressure differential between an internal cavity of the container and an external environment. As such, an increased pressure within an internal cavity of the container may be partially or wholly relieved as a gas/ air is allowed to escape to an external environment surrounding the container through the slider mechanism 2002. This venting may also be occur as discussed above when the slider mechanism 2002 is tilted when being moved from the closed position to the open position. - Additionally, the
lower sled 2036 includes aknob air vent 2202 that extends from theseal surface 2150 through to alower surface 2204 of theknob 2074. Theknob air vent 2202 may be configured to allow air to pass between an internal cavity of the container and an external environment surrounding the container. In one example, air may pass through theknob air vent 2202, through thesecond opening 2024 and out to the external environment. In one example, when thelower sled 2036 and theupper sled 2030 are moved from the closed position depicted inFIG. 33A to the open position schematically depicted inFIG. 33F , thelower sled 2036 may be unsealed from theradial ridges 2164 from theseal surface 2150 and allows air to flow through theknob air vent 2202 between the internal cavity of the container and the external environment. Thisknob air vent 2202 may reduce or prevent glugging due to a relative pressure difference between the internal cavity of the container and the external environment as a liquid is being poured from thefirst opening 2004. - As shown in
FIG. 40 , theknob air vent 2202 may have aknob air vent 2202 that extends from theseal surface 2150 to thelower surface 2204. Theknob air vent 2202 includes afirst vent opening 2206 at thelower surface 2204, a second vent opening 2208 at theseal surface 2150, and a ventinner surface 2210 between thefirst vent opening 2206 and thesecond vent opening 2208.Knob air vent 2202 has a first rounded entry portion 2212 (i.e. fillet radius) that transitions from thelower surface 2204 to the ventinner surface 2210. Similarly,knob air vent 2202 has a second rounded entry portion 2214 (i.e. fillet radius) that transitions from theseal surface 2150 to the ventinner surface 2210 at thesecond vent opening 2208. By adding therounded entry portions upper sled 2030 and thelower sled 2036 may be reduced. Thefirst vent opening 2206 has a first diameter, and thesecond vent opening 2208 has a second diameter, where the first diameter is smaller than the second diameter.
Further, a ratio of the first diameter to the second diameter may be approximately 0.8:1.0 or within a range of 0.7:1.0 and 0.9:1.0. In addition, the ventinner surface 2210 may include a tapered or conical shaped surface that expands as it moves from the firstrounded entry portion 2212 to the secondrounded entry portion 2214, or the ventinner surface 2210 may have a substantially cylindrical shape. A third diameter measured at the smallest region along the vent 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 within a range of 1.0 to 1.25 mm. The first diameter may be within a range of 4 mm and 5 mm, or within a range of 3 mm and 6 mm. Another way of expressing size of the third diameter may be as a ratio of the third diameter to the first diameter. For example, a ratio of the third diameter to the first diameter may be approximately 0.27:1.0, may be within a range of 0.2:1.0 and 0.3:1.0, or may be within a range of 0.2:1 and 0.5:1.0. In some examples, the first rounded portion may have a radius of approximately 2.9 mm or within a range of 2.5 and 3.5 mm while the second rounded portion may have a radius of approximately 3.8 mm or within a range of 3.5 and 4.5 mm. The radius of the firstrounded entry portion 2212 may be smaller than the radius of the secondrounded entry portion 2214. As another way of expressing the size of therounded entry portions rounded entry portion 2212 and the radius of the secondrounded entry portion 2214. For instance, the ratio of the radius of the firstrounded entry portion 2212 to the radius of the secondrounded entry portion 2214 may be approximately 0.76:1, or may be within a range of 0.7:1 and 0.8:1. The geometry of theair vent 2202 may allow air to be released from the container at a rate to prevent any adverse pressure buildup between the contents of the container and the slider mechanism 2002. - The present disclosure is disclosed above and in the accompanying drawings with reference to a variety of examples. The purpose served by the disclosure, however, is to provide examples of the various features and concepts related to the invention, not to limit the scope of the invention. One skilled in the relevant art will recognize that numerous variations and modifications may be made to the examples described above without departing from the scope of the present invention.
