Background Art

[0003] Beverage containers typically have a lid with an opening so that the liquid contained therein can leave the container. The opening may be always open (e.g., without a closable cover) so that the user can drink from the container more easily. However, when the container is moved, the opening is always open, which may cause the liquid contained therein to splash out through the lid. Additionally, the lid of the beverage container often needs to be cleaned between uses. However, known lids for containers have hard-to-reach surfaces and / or otherwise difficult-to-clean areas.

[0018] A lid for a beverage container (e.g., a so-called "travel mug") is described herein. The container lid is configured to prevent liquid contained therein from splashing through the lid during movement of the container. The lid includes a lid body that is sealingly secured to the container body using a peripheral seal, such as a silicone seal. The lid body includes a peripheral wall that expands outwardly so as to be roughly flush with the outer periphery of the container body. In other examples, the peripheral wall may extend slightly beyond or significantly beyond the outer periphery of the container body. This may facilitate removal of the lid from the container body, and may help direct liquid within the container into the user's mouth during drinking (e.g., by having the user position her lower lip below the outermost edge of the expanded peripheral wall).

[0019] The lid body is configured to form a peripheral well adjacent to the expanded peripheral wall. The peripheral well is disposed around the internal structure. The peripheral well includes structural features that allow free flow of liquid during drinking but prevent liquid from being ejected therethrough during container movement. The depicted configuration includes many of these structural features, but any fewer number of structural features may be combined as needed or desired for a particular application to prevent splashing.

[0020] For example, the underside of the cap (e.g., the surface facing the interior of the container body) slopes upward from the outermost extent near the expanded peripheral wall. Therefore, most of the liquid that is forced upward along the inner wall of the container body due to container movement impacts the underside of the cap and is deflected upward and inward in the container body.

[0021] The bottom surface of the peripheral well (opposite to the lower side) slopes downward as the bottom surface approaches the expanded outer wall, so that the lowest range is adjacent to the expanded peripheral wall. As the lowest range, the peripheral well defines a plurality of openings through which liquid can pass during drinking. Since these openings are located at the lowest range, liquid disposed therein (due to drinking or unintentional liquid movement through the openings due to container movement) will be discharged from the peripheral well and returned to the interior of the container body.

[0022] The liquid that moves through the opening (for example, due to the movement of the container) unintentionally can be ejected upwards into the peripheral well through the opening with significant speed or force. This liquid can contact the lower side of the cover top and deflect back towards the opening. In the configuration described, the lower side of the cover top is generally convex, which will guide the liquid of the injection inward and away from the gap between the peripheral wall and the cover top of the expansion. This deflected liquid can contact the internal structure and be discharged downwards in the peripheral well, so as to be discharged back through a plurality of openings.

[0023] The described configuration also includes a shelf protruding inwardly from the peripheral wall of the expansion. The shelf defines the outermost range of the peripheral well so as to be arranged below the top of the cover. Therefore, the liquid sprayed upward through the opening with a specific force will impact the top of the cover. In the absence of the shelf, the sprayed liquid may otherwise vertically travel along the peripheral wall of the expansion and leave the gap between the peripheral wall of the expansion and the top of the cover.

[0024] Thus, the structure of the perimeter well including one or more of the above features helps prevent liquid within the container from splashing out of the container during movement of the container. The perimeter well presents a winding flow path that can interrupt the movement of liquid therethrough to prevent splashing. However, such a winding flow path can be difficult to clean. Therefore, the cover described herein includes additional features that allow the perimeter well to be easily accessible for cleaning, for example, may include at least one removable component, such as a cover upper portion.

[0025] The upper part of the cover can be made of one or more parts and fixed to the cover body in a removable manner. In an example, the upper part of the cover can be fixed to the internal structure of the cover body. For example, the internal structure can include a throat, a receiver or other features that can enable the upper part of the cover to be fixed thereto. In an example, the throat can include a threaded receiver, which can be threadedly matched with the base of the upper part of the cover so that the upper part of the cover can be fixed to the cover body. For this configuration, it may be desirable to include a thumb turner or other features that can be grasped to help ensure the tight connection between the upper part of the cover and the cover body. Another example of a locking element is depicted in the figures included in this article. In the figure, the internal structure defines a throat including a plurality of locking channels. The bayonet extends from the outer part of the base of the cover and can be inserted into the locking channel. Thereafter, the cover body can be rotated, for example, by a user rotating the thumb turner or other graspable elements, so that the base of the cover is locked in place. In the depicted example, for ease of manufacture, the upper part of the cover is made in two parts, but an integral upper part of the cover can also be used.

[0026] Figure 1 A perspective view of an exemplary container 100 having a container body 102 and a container lid 104 is illustrated. Figure 2 The container cap 104 of the container 100 is shown in a perspective view disconnected from the container body 102. Figure 1 and Figure 2 , the container 100 is illustrated as a drinking tumbler, but may alternatively take the form of a glass, mug, cup, goblet, beer mug, tankard, vessel, beaker, drinking vessel, drinkware, food container, or other vessel for holding a liquid beverage or food for consumption. Although the container 100 is described for liquids, the container 100 may be used to hold any other substance, material, or item as needed or desired.

[0027] The container body 102 has an upper end portion 106, an opposite lower end portion 108, and a middle portion 110, which extends between the upper end portion 106 and the lower end portion 108. The container body 102 defines an internal chamber 112, which is configured to hold a liquid in the internal chamber 112. The upper end portion 106 is open for entering the internal chamber 112, and the lower end portion 108 is closed. The internal chamber 112 extends from the upper end portion 106 into the middle portion 110 and extends toward the lower end portion 108. In an example, the container body 102 is generally cylindrical in shape. In other examples, the container body 102 can have a downwardly tapered profile, wherein the diameter of the upper end portion 106 is greater than the diameter of the lower end portion 108. As illustrated, the container body 102 does not include a handle. In other aspects, the container body can include one or more handles as needed or desired. The container body 102 can be formed of stainless steel. In other aspects, the container body 102 can be formed of glass, ceramic, plastic, etc. or a combination of glass, ceramic, plastic, etc. The container body 102 can also be manufactured to provide isolation for the liquid contained in the container body 102 from the surrounding environment.

[0028] The container lid 104 is configured to be coupled to the container body 102 in a removable manner. The container lid 104 defines one or more liquid flow paths 114, which are used to dispense liquid from the container body 102 when the lid 104 is coupled to the container body 102. In an example, the lid 104 includes a lid body 116 and a lid upper portion 118, which are configured to be fixed to each other in a releasable manner for easy cleaning. The liquid flow path 114 can be at least partially defined between the lid body 116 and the lid upper portion 118. The lid 104 includes a seal 120, which is configured to engage with an inner surface 122 of the container body 102 with a press-fit connection so as to form a seal between the lid 104 and the container body 102, and force the liquid contained therein to flow through the liquid flow path 114. In one aspect, the seal 120 can be a silicone seal. In other examples, the cap 104 may be threadably engaged with the container body 102 as needed or desired.

[0029] Figure 3 A top perspective view of the container lid 104 is shown. Figure 4 The figure shows a bottom perspective view of the container cover 104. Figure 3 and Figure 4, the container cap 104 can be formed as a two-piece component having a cap body 116 and a cap upper portion 118. Additionally, the seal 120 can be supported on the cap body 116. The cap body 116 includes an outer peripheral wall 124 having a first end 126 and an opposite second end 128. The first end 126 and the second end 128 define a longitudinal axis 130 of the cap 104. In an example, the outer peripheral wall 124 is generally cylindrical in shape and forms an outer side wall of the cap body 116. The first end 126 of the outer peripheral wall 124 expands outwardly relative to the longitudinal axis 130. The expansion portion can have a curved shape, wherein the diameter of the outer peripheral wall 124 increases until the terminal end of the outer peripheral wall 124 is reached. In other examples, the expansion portion can have an inclined shape (e.g., a linear shape) as needed or desired.

[0030] In operation, the upper end portion 106 of the container body 102 (both at Figure 1 104 and 106. The flared first end 126 of the outer peripheral wall 124 can at least partially cover the upper end portion 106 of the container body 102. In one aspect, the flared first end 126 can protrude radially from the outer peripheral surface of the container body 102. In another aspect, the flared first end 126 can be substantially flush with the outer peripheral surface of the container body 102. The flared first end 126 can facilitate removal of the cap 104 from the container body 102 and can help direct liquid flow through the cap 104 and into the user's mouth.

[0031] The lid body 116 also includes an internal structure 132 disposed within the outer peripheral wall 124. The internal structure 132 is connected to the outer peripheral wall 124 by a well wall 134 extending between the internal structure 132 and the outer peripheral wall 124, and in an example, the well wall can be generally convex in shape. In an example, the well wall 134 extends from the second end 128 of the outer peripheral wall 124. The well wall 134 at least partially defines a plurality of openings 136. The openings 136 can be spaced circumferentially around the longitudinal axis 130 and form a portion of the liquid flow path 114 through the lid 104. For example, the opening 136 can form an inlet for liquid to flow from the container body 102 into the lid 104.

[0032] The upper cover 118 includes: a cover base 138 configured to be fixed to the internal structure 132 of the cover body 116 in a releasable manner, and a cover top 140. The cover top 140 is fixed to the cover base 138. The cover top 140 at least partially covers the opening 136, so that the liquid flow path 114 through the cover 104 is not a linear path. On the contrary, the liquid flowing through the liquid flow path 114 must make one or more turns to be discharged from the cover 104. The cover top 140 is spaced apart from the inner surface 142 of the outer peripheral wall 124, so that a gap 144 is formed between the cover top 140 and the inner surface 142. The gap 144 can form an outlet for liquid to flow out of the cover 104. In the example, the gap 144 extends completely circumferentially around the longitudinal axis 130.

[0033] The cap base 138 includes a thumb turn 146 that is accessible from the second end 128 of the cap body 116 when the cap upper portion 118 is secured to the cap body 116. The thumb turn 146 is configured so that a user can easily remove the cap upper portion 118 from the cap body 116 for cleaning. The thumb turn 146 is further described below.

[0034] Figure 5 An exploded perspective top view of the container cover 104 is shown. Figure 6 The figure shows an exploded perspective bottom view of the container cover 104. Figure 5 and Figure 6 , the container cover 104 includes a cover body 116 and a cover upper portion 118 formed by a cover base 138 and a cover top 140. The cover body 116 includes an outer peripheral wall 124, an internal structure 132, and a well wall 134. In an example, the cover body 116 can have an integral construction, and the outer peripheral wall 124, the internal structure 132, and the well wall 134 are integrally formed. In one aspect, the cover body 116 can be formed of a plastic-based material.

[0035] The internal structure 132 defines a central throat 148. The central throat 148 is generally cylindrical in shape and extends in an upward direction from the wellbore wall 134. The central throat 148 defines an orifice 150 extending through the cover body 116. In the example, the central throat 148 is centered within the cover body 116 and is aligned with the longitudinal axis 130 (eg, Figure 314). The central throat 148 has an inner circumferential surface 152, wherein one or more locking channels 154 are defined in the inner circumferential surface 152. In the example, three locking channels 154 are defined within the inner surface 152 and are circumferentially spaced around the inner surface 152. An outer peripheral surface 156 of the central throat 148 is radially spaced from the inner surface 142 of the outer peripheral wall 124. Within the cover body 116, the inner surface 142 of the outer peripheral wall 124, the well wall 134, and the outer surface 156 of the central throat 148 at least partially define a peripheral well 158 extending radially outward from the central throat 148. The peripheral well 158 has a plurality of openings 136 disposed around the central throat 148.

[0036] The cover upper portion 118 includes a cover base 138 and a cover top 140. The cover base 138 has a top end 160 and an opposite bottom end 162. The bottom end 162 has a thumb turner 146 extending from the bottom end 162. In an example, the thumb turner 146 can be a tab that extends at least partially over the bottom end 162 and is configured to enable a user to grasp and rotate the cover upper portion 118, as described herein. The top end 160 of the cover base 138 is configured to receive at least a portion of the cover top 140. In an example, the cover base 138 is generally cylindrical in shape, with a recess 164 that receives a portion of the cover top 140. The cover base 138 also includes a plurality of bayonet 166, which are shaped and sized to be at least partially accommodated in the corresponding locking channels 154 of the central throat 148. In one aspect, each of the bayonet 166 can be a cylindrical protrusion extending radially from the outer surface of the cover base 138. In other examples, the cover base 138 may include the locking channel while the central throat 148 includes the bayonet 166 and such that the connection structure is reversed.

[0037] The cover top 140 includes a bottom cylindrical wall 168 having a top cover 170. The cover 170 is enlarged relative to the bottom cylindrical wall 168 and extends substantially radially outward. When the cover upper portion 118 is assembled, a gasket 172 can be disposed between the cover top 140 and the cover base 138. In an example, the gasket 172 can be disposed between the top end portion 160 of the cover base 138 within the recess 164 and the bottom cylindrical wall 168 of the cover top 140, and as shown in FIG. Figure 8 shown.

[0038] In an example, the cover upper portion 118 is formed as an assembly of a cover base 138 and a cover top 140. The cover base 138 can be coupled to the cover top 140 so that once connected together, the cover base 138 is fixed to the cover top 140 and cannot be removed or cannot be removed without damaging the components. In one aspect, the cover base 138 can be ultrasonically welded to the cover top 140. In another aspect, the cover base 138 can be snap-fitted or press-fitted to the cover top 140. In yet another aspect, the cover base 138 can be threaded onto the cover top 140. In yet another aspect, the cover base 138 can be integrally formed with the cover top 140 (e.g., via an additive manufacturing process or a molding process). In an example, the outer surface of the bottom cylindrical wall 168 of the cover top 140 and the inner surface of the recess 164 of the cover base 138 can include one or more ribs 173 (e.g., Figure 8 ), one or more ribs 173 facilitate the fixation between the cover top 140 and the cover base 138. In one aspect, one or more ribs 173 are not threads.

[0039] Figure 7 The bottom plan view of the container lid 104 is illustrated. As illustrated, the lid upper portion 118 is coupled to the lid body 116. More specifically, the lid base 138 is housed within the central throat 148 so that the bayonet 166 is at least partially received within the locking channel 154. This lockability ensures that the lid base 138 is fixed within the central throat 148 during use of the lid 104, but allows the user to release the lid upper portion 118 from the lid body 116 and remove the lid upper portion 118 for cleaning. To release the lid upper portion 118, the lid upper portion 118 can be rotated about the longitudinal axis 130 ( Figure 3 shown) rotation.

[0040] Also in Figure 7 , the outer peripheral wall 124 is shown as having a first end that expands radially outward. At the second end of the outer peripheral wall 124, the seal 120 at least partially protrudes radially for engagement with the container body. The well wall 134 extends between the outer peripheral wall 124 and the central throat 148. The opening 136 forms an inlet for fluid to enter the cover 104. The cover top 140 ( Figure 6 134, the cover top 140 is configured to cover the opening 136 so that the liquid flow path 114 ( Figure 3 136 ).

[0041] Figure 8 The diagram shows the Figure 78-8 of the cross-sectional view of the container cover 104. Some components are described above and do not need to be further described. The cover body 116 has a first end 126 and a second end 128 of the outer peripheral wall 124 extending along the longitudinal axis 130. The outer diameter 174 of the second end 128 is less than the outer diameter 176 of the first end 126 because the first end 126 expands radially outward. Therefore, the first end 126 has a terminal lip 178 protruding radially outward at the first end 126. Near the second end 128 of the outer surface of the outer peripheral wall 124, an annular channel 180 is defined, and the seal 120 is at least partially located in the annular channel 180. The peripheral well 158 is defined between the outer peripheral wall 124, the well wall 134 and the central throat 148.

[0042] The inner surface 142 of the outer peripheral wall 124 has a shoulder 182 formed at the second end 128, and the shoulder 182 defines a shelf 184 extending in the radial direction. The shelf 184 protrudes inwardly from the outer peripheral wall 124 toward the central throat 148 and into the peripheral well 158, and is disposed between the first end 126 and the second end 128. In the example, the shoulder 182 is a portion of the outer peripheral wall 124, the thickness of which portion of the outer peripheral wall 124 (e.g., the thickness in the radial direction) is greater than the thickness of the wall near the first end 126. Therefore, the inner diameter of the outer peripheral wall 124 at the shoulder 182 and the second end 128 is smaller than the inner diameter of the outer peripheral wall 124 at the first end 126.

[0043] The well wall 134 extends between the second end 128 of the outer peripheral wall 124 and the central throat 148 so as to support the central throat 148. In the example, the central throat 148 is spaced apart from the second end 128 and offset 186 relative to the second end 128. This results in the lower side surface 188 of the well wall 134 being concave in shape. On the one hand, the apex of the concave surface is located at about one quarter of the height of the cover body 116 along the longitudinal axis 130. On the other hand, the apex of the concave surface is located at about one third of the height of the cover body 116.

[0044] The bottom surface 190 of the peripheral well 158 (e.g., the surface of the well wall 134 opposite the lower side surface 188) slopes in a downward direction from the central throat 148 toward the outer peripheral wall 124 and the shoulder 182. In various aspects, the downward slope of the bottom surface 190 can be curved or linear as needed or desired. In an example, the lower portion of the cover base 138 from which the thumb turner 146 extends can be shaped to correspond to the concave shape of the well wall 134.

[0045] A plurality of openings 136 are defined in the well wall 134 to define a fluid inlet into the peripheral well 158. In one aspect, the openings 136 are defined by the cap body 116 near the lowest extent of the peripheral well 158. This configuration allows the liquid in the peripheral well 158 to drain back into the container body when the container body is oriented in a generally upright position. In one aspect, the openings 136 can be defined in part by the shoulder 182 and in part by the well wall 134. In other aspects, the openings 136 can be completely defined in the well wall 134. In yet another aspect, the central axis of each opening 136 is not parallel to the longitudinal axis 130.

[0046] like Figure 8 As shown in , the cover upper portion 118 is coupled to the cover body 116. Therefore, the cover base 138 is received in the central throat 148 in a lockable manner, wherein the cover 170 of the cover top 140 is at least partially disposed above the central throat 148, and the finger turner 146 extends below the well wall 134. When the cover upper portion 118 is coupled to the cover body 116, the cover top 140 at least partially covers the peripheral well 158. In the example, the cover 170 of the cover top 140 has an outer peripheral edge 192, which is the radially outermost extent of the cover top 140. The outer peripheral edge 192 can be at least partially disposed above the shelf 184. Thus, the shelf 184 is at least partially disposed below the cover top 140. The outer peripheral edge 192 of the cover 170 has a diameter greater than the inner surface diameter of the shoulder 182. Therefore, the cover 170 of the cover top 140 at least partially covers the opening 136. In one aspect, the cover 170 of the cap top 140 completely covers the opening 136. As used herein, covering the opening 136 means that the cover 170 is positioned axially above the opening 136.

[0047] The outer peripheral edge 192 of the cover 170 has a diameter that is smaller than the inner surface diameter of the outer peripheral wall 124. Thus, a gap 144 is formed between the cap top 140 and the cap body 116 between the outer peripheral edge 192 of the cover 170 and the outer peripheral wall 124 and the shoulder 182 of the cap body 116. The gap 144 allows liquid to flow out of the cap 104 from the peripheral well 158. In one aspect, the gap 144 extends completely circumferentially around the longitudinal axis 130. This configuration enables a user to drink from any position around the first end 126 of the cap body 116.

[0048] When the cover upper part 118 is fixed to the cover body 116, the cover 170 of the cover top 140 is axially separated from the well wall 134, so that a splash chamber 194 is defined therein. The splash chamber 194 is a volume at least partially located in the cover 104, which makes it difficult for liquid to flow through undesirably. On the one hand, the splash chamber 194 has basically no structure except its boundary components. The splash chamber 194 can be a generally cylindrical shape with axial dimensions, radial dimensions and circumferential dimensions. The inlet of the splash chamber 194 is defined by the opening 136, and the outlet for the splash chamber 194 is defined by the gap 144 between the cover top 140 and the outer peripheral wall 124. On the one hand, the splash chamber 194 extends completely circumferentially around the longitudinal axis 130. The opening 136 and the gap 144 are positioned relative to each other so that the liquid flow path 114 of the liquid traveling through the splash chamber 194 includes one or more curves. On the one hand, the liquid flow path 114 is not linear or substantially linear. For example, the liquid flow path 114 is forced to turn around the outer perimeter 192 of the cover 170 and the shelf 184 of the shoulder 182 .

[0049] In operation, when the container body 102 (such as Figure 1 and Figure 2 When liquid in the container 104 (shown in the figure) splashes around and travels through one or more of the openings 136, the liquid flow path 114 is shaped so as to reduce or prevent the liquid from traveling through the gap 144 and leaving the lid 104. Instead, the liquid is captured in the splash chamber 194 and then allowed to drain back into the container body 102 via the openings 136 and when the container body 102 is positioned upright. However, when the user purposefully drinks from the container and tilts the lid 104 in the drinking configuration, the liquid can flow through along the inner surface 142 of the outer peripheral wall 124 and more gently flow through the splash chamber 194 and leave the gap 144. Both the opening 136 and the gap 144 are positioned on the radially outward end of the splash chamber 194, but the opening 136 and the gap 144 are not axially aligned along the longitudinal axis 130. Because the opening 136 and the gap 144 extend circumferentially around the longitudinal axis 130, air can enter the container body during drinking, making the liquid flow through the liquid flow path 114 relatively gentle and consistent. In one aspect, the edge of shelf 184 can be rounded. In another aspect, the underside of cover 170 of lid top 140 is concave and can correspond to the shape of well wall 134. Liquid flow path 114 is always open in lid 104, and neither opening 136 nor gap 144 has any cover (e.g., pivoting cover or sliding cover) covering them. Therefore, it is the structural configuration of lid 104, rather than the user-movable cover of the liquid flow path, that provides the splash protection function as described herein.

[0050] In an example, the upper side of the cover 170 can be convex. When the cap top 118 is connected to the cap body 116, the vertex 196 of the cap top 140 is arranged below the upper extension of the first end 126 of the cap body 116. This configuration allows the liquid that the user does not consume to be discharged back into the container body 102 when drinking. On the one hand, the vertex 196 is aligned with the starting point of the expansion of the first end 126 of the outer peripheral wall 124. On the other hand, the vertex 196 is arranged in the upper half of the cap body 116. In another example, the vertex 196 is arranged in the upper third of the cap body 116.

[0051] Fig. 9 The diagram shows the Figure 7 9-9 of the cross-sectional view of the container cover 104. Some components are described above and do not need to be described further. Although the splash chamber 194 helps to reduce or prevent liquid from undesirably flowing through the cover 104, the splash chamber 194 also makes it difficult to clean the cover 104. Therefore, the cover upper portion 118 is configured to be removable from the cover body 116 for easy cleaning. As described above, the cover base 138 is at least partially received in the central throat 148 in a lockable manner so that the cover upper portion 118 is fixedly connected to the cover body 116 while still allowing the cover upper portion 118 to be disconnected as needed or desired.

[0052] In the example, the cover base 138 is lockably mated with the central throat 148 via a bayonet connection. A locking channel 154 defined in the central throat 148 includes an axial component 198 and a circumferential component 200. The locking channel 154 is configured to receive a bayonet 166 protruding from the cover base 138. The cover base 138 of the cover upper portion 118 having the bayonet 166 is configured to be axially inserted into the axial component 198. For example, the cover base 138 can be inserted from the top end of the central throat 148. Once the bayonet 166 is positioned in the circumferential component 200, the cover upper portion 118 is at least partially capable of rotating 202 about the longitudinal axis 130 to lock the bayonet connection and position the bayonet 166 to be captured below the notch formed in the locking channel 154. In order to unlock the bayonet connection and remove the cover upper portion 118 from the cover body 116, the coupling steps are reversed. In one aspect, the open end of the axial member 198 may include tapered sides to aid in capturing the bayonet 166 .

[0053] It should be understood that, although a bayonet connection is described above, the cap upper portion 118 can be removably coupled to the cap body 116 via any other connection type that facilitates the operation of the cap 104 as described herein. For example, the cap base 138 and the central throat 148 can be threadedly connected. In other examples, the cap base 138 can be coupled to the central throat 148 via a snap fit or press fit connection. In other aspects, the cap upper portion 118 can be integrally or integrally made with the cap body 116 so that the cap upper portion 118 cannot be removed from the cap body 116. Although cleaning the container cap 104 may be more difficult, the splash-proof function of the cap 104 is maintained.

[0054] The technology described herein relates to a lid for a beverage container. The lid includes a lid body and a lid upper portion, which are configured to define a liquid flow path therein, the liquid flow path being coiled and limiting or preventing liquid from overflowing the lid during container movement. Additionally, the lid upper portion is removably coupled to the lid body so that the lid can be easily disassembled for easy cleaning.

[0055] Many parts of container lid can be referred to as having roughly cylindrical feature, circular feature, annular feature or tapered feature.Such feature can be referred to as circumference, radius, outer surface, inner surface and / or other terms suitable for limiting such feature, or limited by circumference, radius, outer surface, inner surface and / or other terms suitable for limiting such feature.It should be noted that such feature can be elliptical, polygonal etc. alternatively.As used herein, term "axial" and "longitudinal" refer to the direction and orientation extending roughly parallel to the center line of lid.In addition, term "radial" and "radially" refer to the direction and orientation extending roughly perpendicular to the center line of lid.In addition, as used herein, term "circumferential" and "circumferentially" refer to the direction and orientation extending arcuately around the center line of lid.
