Definitions
- Cup lids can be used to seal the top opening of a beverage container.
- vendors often provide disposable cup lids with cups or other containers that contain drinks such as coffee, tea, soda, etc.
- Such cup lids include an annular mounting portion that allows the lid to attach and/or seal with the cup.
- the lids have an opening or spout that allows users to drink or otherwise pour fluid from the cup or container while the lid is in place.
- Some cup lids have an integrated closure member that facilitates closing or covering of the opening or spout.
- the closure members can help inhibit spillage or undesired leaking through the opening when the opening is not in use.
- some lids have an arm with a tab at a distal end that extends from the periphery of the lid. A user may flex the arm to insert the tab into the drink opening of the lid, thereby closing or plugging the opening.
- Some cup lids have printed text that displays promotional, warning, or other types of information.
- some cup lids will include printed text that warns consumers about the temperature of the contents of the cup, or that provides branding information in the form of logos or product names associated with the beverage.
- Some cup lids will also include other information relating to the size of the cup, or whether or not the lid is recyclable. Users may find this printed text difficult to read for various reasons.
- the printed text may be formed via a deformation in the lid itself, and thus have the same color as the surrounding portion of the lid. As a result, the text may not be readily discernable in certain light or at certain viewing angles. Further, the arm or sealing mechanisms may lie over the text, thereby obscuring, hiding, or otherwise making the text difficult to read.
- this application discloses and describes a lid assembly that includes a cover and a cap.
- the cover is configured to attach to a cup opening.
- the cover includes an annular mounting portion that secures and/or seals the cover to a top rim of the cup.
- the cover also has an annular upper ridge with a drink opening that allows fluid contents of the cup to be poured from the cup.
- An annular outer sidewall extends upward from the mounting portion to an outer peripheral edge of the annular upper ridge.
- the cover also has an annular inner sidewall circumscribing an interior portion.
- the annular inner sidewall has a surface that slopes downward and inward from the annular upper ridge to the interior portion.
- the cap is attachable to the cover and includes a main body and a flap that pivotally extends from the main body.
- the flap has a hinge and a plug at an end of the flap.
- the plug can be inserted into the drink opening to form a seal that inhibits fluid within the container from leaking out of the drink opening.
- the cover has printed text on the sloped surface of the annular inner sidewall. The printed text extends across a location of the annular inner sidewall that is opposite the drink opening.
- the interior portion of the cover includes a first post and the main body of the cap includes a corresponding second post defining a cavity on the underside of the cap.
- the first post is configured to fit within the second post with a friction fit to help secure the cap to the cover.
- the second post is also configured to form a securable connection with a cavity defined on an underside of the plug. In this way, the flap can be pulled back to the second post and secured in place when it is not sealing the drink opening.
- a lid assembly for covering an opening of a cup includes a cover configured to cover the opening of the cup and a cap configured to be selectably attached to the cover.
- the cover includes an annular mounting portion configured to secure the cover to a top rim of the cup, an annular sidewall that extends upwardly from the mounting portion to an outer periphery of an upper ridge of the cover, and a drink opening defined in the upper ridge.
- a tapered sidewall extends around an interior portion of the cover.
- the tapered sidewall includes one or more regions at which the tapered sidewall tapers gradually downward from an inner periphery of the ridge towards respective one or more inner vertical surfaces of the interior portion.
- the cap includes a main body configured to be positioned over and to cover the interior surface of the interior portion of the cover.
- the cap also includes a flap that is pivotally connected to the main body.
- the cap includes a plug at an end opposite a hinge or pivot end configured to be inserted within the drink opening and to seal the drink opening.

- the lid assembly is arranged to form a securable attachment to the opening of the cup, such that the lid remains in place on the cup when the cup is tipped to dispense fluids.
- the lid assembly may form a tight seal that inhibits fluid from within the cup from leaking from any undesirable locations, namely, from any locations other than through the drink opening.
- the lid assembly generally comprises a cover component and a cap component that are separably attachable to one another.
- the cover component generally covers the top of a cup, and includes a drink opening through which a user may drink or otherwise pour out the cup's contents.
- the cap component attaches to the cover component and allows the drink opening to be closed or sealed. More specifically, the cap component includes a flap and a plug that is pivotable between open and closed positions so that the drink opening can be closed and/or sealed to inhibit unwanted dripping, leaking, or spilling of the cup's contents through the drink opening, and to help improve the thermal insulation properties of the lid assembly.
- the cap may be an optional member.
- the cap may be configured to be secured to or released from the cover by a user, such as a consumer.
- FIG. 1 illustrates a perspective view of one example of a lid assembly 100 for covering a drink cup.
- the lid assembly 100 includes a cover 105 that is configured to attach to the cup and may be used to substantially seal the contents therein within the cup.
- the lid assembly 100 also includes a cap 205 that may be separately attached to the cover 105 .
- the cover 105 includes an annular mounting portion 110 configured to secure the cover 105 to a top rim of the cup.
- the annular mounting 110 portion forms a seal that inhibits fluid from within the cup from spilling or otherwise leaking from the cup around the top rim.
- An annular sidewall 115 extends upwardly from the mounting portion 110 to an outer periphery of an upper ridge 120 of the cover 105 .
- a drink opening 122 is defined in the upper ridge 120 as shown in FIG. 2 .
- a tapered sidewall 125 extends around the interior portion of the cover 105 .
- the sidewall 125 includes a first set of regions where the sidewall 125 tapers gradually downward from the inner periphery of the ridge 120 towards a first set of vertical surfaces 130 . That is, each region tapers towards a different vertical surface 130 .
- the sidewall 125 also includes a set of ledge regions 127 where the sidewall continues to taper past the first set of vertical surfaces 130 to a second set of vertical surfaces 131 .
- An interior surface 135 of the interior portion extends between lower edges of the first set of vertical surfaces 130 to thereby substantially cover the entire area of the interior portion.
- lower edges of the second set of vertical surfaces 131 may be separated from the interior surface 135 by a distance to thereby define a gap or undercut 132 between lower surfaces of the ledge regions 127 and the interior surface 135 .
- the gap 132 width may be slightly larger than the thickness of the cap 205 to facilitate insertion of edge portions of the cap 205 into the gaps 132 below the ledge regions 127 .
- the gap width may be about 0.100′′.
- the cap includes a main body 210 , and a flap 220 that is pivotally connected to the main body 210 .
- the main body 210 is configured to be positioned over and to substantially cover the interior surface 135 of the interior portion of the cover 105 . While a solid surface is illustrated, it is understood that the main body 210 does not generally play a role in sealing the contents within the cup. Therefore, one or more openings for decorative purposes, to reduce material usage, etc., may be provided in the main body 210 .
- the main body 210 of the cap 205 may define a protruded surface 215 .
- the interior surface 135 of the cover 105 may define a complementary indented surface 140 configured to receive the protruded surface 215 .
- the protruded surface 215 and the indented surface 140 cooperate to control alignment of the cap 205 within the interior portion of the cover 105 .
- the flap 220 is pivotally connected to the main body 210 .
- the flap 220 is connected via a resilient portion or hinge 230 .
- the resilient portion 230 may have a generally curved cross-section and may be sized to facilitate opening and closing of the flap 220 for a repeated number of times without breaking.
- the resilient portion 230 may be configured to extend somewhat below a plane within which the main body 210 lies. The distance by which the resilient portion 230 is below the main body 210 may be related to the radius of the curved section.
- the interior surface 135 of the cover 105 may define an indentation 145 with a depth that at least matches the distance by which the resilient portion 230 extends below the main body 210 to prevent substantial interference between the interior surface 135 of the cover 105 and the resilient portion 230 of the flap 220 .
- the flap 220 includes a plug 225 configured to be inserted within the drink opening 122 and to seal the drink opening 122 when the flap 220 is placed in the closed configuration, as illustrated in FIG. 1 .
- the flap 220 may also include a handle or tab portion 230 arranged above the plug 225 .
- the handle 230 may be pinched between a user's thumb and forefinger to facilitate removal of the plug 225 from the drink opening 122 .
- the gripping portion or handle 243 is also arranged relative to the protrusion 215 in the main body 210 , such that when the flap 220 is placed in the fully open position (see FIG. 4 ), the handle 230 enters the cavity defined by the protrusion 215 and engages an inside edge of the protrusion 215 to thereby retain the flap 220 in the open configuration.
- Other methods known in the art may be utilized to secure the flap 220 in the open configuration.
- the cover 105 and cap 205 may come pre-assembled or may be provided separately. When provided separately, a user may insert the cap 205 into the interior of the cover 105 .
- the disk may be sized to provide a friction fit against the inner vertical surfaces 130 at which the first set of regions of the tapered sidewall 125 terminate to thereby secure the cap 205 within the interior portion of the cover 105 .
- the diameter of the main body may be sized so that the edges of the main body 210 of the cap 205 resiliently snap into the gap 132 between the lower surfaces of the ledge regions 127 and the interior surface 210 of the cover 105 when the cap 205 is attached to the cover.
- the angle at which the tapered sidewall 125 tapers may be adjusted to allow the disk portion 210 to slide more easily into the fully sealed position.
- FIG. 5 illustrates a perspective view of a second lid assembly 500 embodiment for covering an opening of a drink cup.

- the interior sidewalls of the groove 605 a of the cover 505 may have a negative draft angle of about 3 to 7 degrees that match corresponding positive draft angles of the protrusion 606 . Other draft angles may be suitable. While the illustrated grooves 605 ab extend around most of the respective peripheries, it is understood that the grooves 605 ab may extend to a lesser amount or that the grooves 605 ab may not extend by the same amount.
- the groove 605 a in the cover 505 may extend around the periphery as illustrated, while the groove 605 b in the cap 507 may extend around the cap 507 to a lesser degree, or be formed of segmented sections that fit within the groove 605 a of the cover 505 .

- the cavity 705 facilitates relaxation of the alignment requirements between the respective openings 617 ab by providing a conduit between the openings 617 ab .
- the openings 617 ab may be spaced laterally apart from one another to minimize fluid leakage through the openings 617 ab that may otherwise occur when the two openings 617 ab are aligned.
- the lid 100 has been described with reference to certain embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope.
- the set of regions that terminate at the first set of vertical sidewalls 130 may form one continuous region and the first set of vertical sidewalls 130 may be one continuous sidewall that generally extends around the interior portion of the cover.
- the main body may not be sized to provide a friction fit against the first set of vertical surfaces 130 . That is, the main body 210 may be held in place via the gap/undercut 132 below the ledge portions 127 alone.
- the main body 210 may also be sized to provide a friction fit against the first set of vertical surfaces 130 .
- the resilient portion of the flap 220 may be arranged above the main body 210 which may facilitate elimination of the indentation 145 in the interior surface 135 of the cover 105 .
- the lid may be made from a variety of materials including polystyrene, polypropylene, paper, and may include fillers such as talc or calcium. Paper materials may include paper from tree, sugarcane bagasse, fiber, etc. Other materials known to those skilled in the art, such as biodegradable and/or compostable materials, may also be utilized.
- the cover 105 and cap 205 may be made from different materials and have the same or different thickness. For example, the cap and cover may have a thickness of about 0.015′′. Alternatively, one of the cap and cover may have a thickness of about 0.012′′, and the other may have a thickness of about 0.015′′.
- the cover 105 and cap 205 may be manufactured via thermoforming, injection molded, pulp molded, etc.
- alignment features i.e., protrusions in the cap and indentations in the cover, or vise-versa
- shape of the main body and the sidewall at which the tapered sidewall of the cover terminates may be keyed to align the main body within the interior portion of the cover.
- the cap may be secured to the cover via an adhesive, friction welding, etc.
- the main body 210 may have a diameter smaller than that of the tapered sidewall 125 at an inner edge thereof.
- the main body 210 may include a retention protrusion configured to maintain the flap in the open configuration.
- lid assemblies described herein can be used to improve the manner that readable indicia, or printed text, is displayed on the lid assembly. That is, some of the lids are configured and arranged so that the printed text is easier for a user to identify, recognize, and read.
- the terms “readable indicia” or “printed text” refer to text provided on the lid or its components in a recognizable format.
- the “printed text” or “readable indicia” can be printed with ink or paint, or it can be formed as a deformation in the lid material, for example, by being stamped, etched, engraved, embossed, or molded into the material that forms the lid or its components.
- the printed text or readable indicia may include letters, numbers and punctuation, but it can also include other graphics such as logos, symbols, shapes, designs, patterns, images, bar codes, Braille patterns, and the like.
- the terms “printed text” and “readable indicia” as used throughout this application are meant to be interchangeable with one another.
- the printed text can be arranged in a manner so that a user drinking from the cup can readily recognize and read the printed text on the lid assembly.
- the printed text is arranged on a sloped surface that is angled toward a location that generally corresponds with an eye level of a user holding or drinking from the cup.
- Providing the printed text on a sloped surface can help improve the visibility of the printed text by providing a more direct line of sight with a cup-holder's eyes, and by mitigating reflections of light off the surface of the lid.
- the printed text is provided as a deformation in the lid material, meaning that the text itself is merely a contoured texture and does not necessarily stand out by way of contrasting colors or shading.
- reflections, viewing angles, and other factors can diminish a user's ability to read or recognize the printed text.
- the printed text may be closer to perpendicular with a cup user's line of sight. Not only can this help make the printed text easier to read, it can also make the printed text stand out more and draw the attention of a cup user.
- providing the printed text on a sloped surface can also help improve the clarity of the printed text itself. For instance, where printed text is formed by a stamping or molding process, producing the printed text on a sloped surface can mitigate, inhibit, or reduce undesirable ghosting effects or other issues that can result from the molding or stamping processes, which can make the printed text blurrier or otherwise more difficult to read.
- Some implementations provide the printed text in a manner so that the printed text is not covered or obstructed by other objects, such as a flap or a sealing mechanism. This can be accomplished by arranging a flap or sealing mechanism so that it leaves a portion of the lid assembly uncovered, or unobstructed in both an open or closed position.
- a lid may provide for unobstructed text by arranging a securing post in or near the center of the lid assembly, so that the flap secures to the centralized post without covering or resting over at least a portion of the lid assembly on an opposite side of the post. The text on the lid assembly opposite the flap will therefore remain uncovered and readable at all times, regardless of whether the flap is in an open or closed position.
- the shape of the cover and cap components are configured to provide a more aesthetic appearance.
- some examples configure the shape of the cap, or the shape of the outer periphery of the cap so that it corresponds with the shape of certain components or portions of the cover.
- the shape of the outer perimeter of the cap may be designed to correspond with the outer periphery of an interior portion of the cover, so that the peripheral edge of the cap generally aligns with the outer periphery of the interior portion when installed on the lid assembly. Matching these shapes can align two edges so that they appear as a single edge to a cup user, and give the impression that the lid assembly is a single piece, rather than two separate pieces.
- This single edge look may appear less busy, sleeker, and otherwise more visually appealing to consumers.
- Matching the shape of the cap and interior portion of the cover also provides a relatively large area on the cap in which printed text may be provided, such as a trademark, logo, or other information, as described in more detail below.
- Some features described herein also allow for an improved connection between the separate cap and cover components of the lid assembly.
- some examples utilize a centralized post in the cover, and a corresponding cavity in the cap that is designed to form a tight, friction fit with the centralized post.
- This post can improve the securement of the cap to the cover, and inhibit unwanted lifting or separation that can result from repeated lifting and movement of the flap between the open and closed positions.
- the arrangement of the centralized post allows for more freedom in the arrangement between the grooves of the cover and cap, such that the cap can take on different shapes or attach to the cover in different ways while still maintaining a firm fit onto the cover 505 .
- the arrangement of the centralized post can replace the groove configuration altogether, such that the post is the only friction connection holding the cap to the cover.
- FIGS. 8-16 present examples of a lid assembly that utilizes many of the features described above.
- FIG. 8 illustrates a perspective view of an example of a lid assembly 800 comprising a cover 805 and a cap 807 with printed text on the cover 805 and the cap 807 .
- the lid assembly 800 in FIG. 8 is shown in an assembled state, namely, with the cap 807 secured to the cover 805 .
- FIGS. 9, 10, and 11 show exploded top perspective, side, and bottom perspective views, respectively, of the lid assembly 800 , that is, with the cap 807 removed from the cover 805 .
- FIGS. 8-11 is shown with a flap 840 that is in an open position, namely, the flap 840 is away from, and not closing off the drink opening 822 .
- the flap 840 is held in the open position by securing the plug 845 (shown in FIG. 14 ) to the post 915 b .
- FIGS. 12 and 13 show a perspective and top view, respectively, of the cover 805 component by itself, removed from the cap 807 .
- FIG. 14 shows a top view of the cap 807 by itself, removed from the cover 805 .
- FIGS. 15 and 16 show side, cross-sectional views of the cap 807 in an open configuration, and the cover 805 , respectively.
- the lid assembly 800 of FIGS. 8-16 may be similar or even the same as the lid assembly 500 shown and described with respect to FIGS. 5-7 , with the exception that lid assembly 800 includes printed text 852 formed into the cover 805 and cap 807 components.
- the printed text 852 is shown as a deformation in the material that forms the cover 805 or cap 807 . That is, the printed text 852 is imprinted into the material by way of an indentation or engraving. This can be formed via a variety of different techniques, including, for example, by molding, stamping, thermosetting, or other techniques.
- the printed text 852 includes warning text 852 a that informs users of potential hazards associated with the cup or the contents therein.
- the printed text 852 also includes branding information 852 b that identifies or promotes products or brands, such as that of the lid manufacturer, the cup manufacturer, or the provider of the contents within the cup (e.g., a particular restaurant or coffee shop).
- the branding information 852 b can include trade names or other non-alphanumeric graphics such as logos, symbols, or other images.
- the printed text 852 also includes informative text 852 c that provides useful information relating to the lid, cup, or contents.
- the informative text 852 c can be used to identify the size or volume of the cup, instructions on how to assemble or manipulate the lid or components, information about the contents served in the cup, the material that the cup or lid is formed from, whether the cup and/or the lid is recyclable, production or batch information associated with the lid or the cup, or patent or other intellectual property markings, to name but a few examples.
- the lid assembly 800 generally includes many of the features described above with reference to lid assembly 100 and lid assembly 500 .
- the cover 805 of the lid assembly 800 includes an annular mounting portion 810 , an annular outer sidewall 815 that extends upwardly from the mounting portion 810 to an outer peripheral edge 823 of the annular upper ridge 820 of the cover 805 , and a drink opening 822 that is defined in the upper ridge 820 .
- An annular inner sidewall 825 extends between the inner peripheral edge 824 of the upper ridge 820 and the interior portion 835 , and intersects the interior portion 835 at an outer periphery 951 , which at least partially defines the shape of the interior portion 835 .
- the annular inner sidewall 825 is sloped downward and inward between the annular upper ridge 820 and the interior portion 835 .
- the annular inner sidewall 825 includes printed text 852 along the sloped surface on a side 860 of the lid opposite the drink opening 822 . Providing the printed text 852 in this location and on a sloped surface allows the printed text to be displayed in a manner that is recognizable and readable to a user as a user holds and/or drinks from the cup.
- the angle of the sloped surface can vary depending on a variety of factors including, but not limited to, the size of the cup and/or lid, the size of the printed text, and the radius of curvature of the annular inner sidewall 825 .
- the slope, or angle of the annular inner sidewall 825 can vary among locations about the periphery of the cover 805 .
- the slope angle of the portion of the annular inner sidewall comprising printed text 860 may differ from the slope angle of the annular inner sidewall adjacent the drink opening 862 , which can be seen from the cross-sectional view of the cover 805 of FIG. 16 .
- the slope angle ⁇ at a particular point is defined by the angle formed between an axis tangent to the annular inner sidewall at the particular point and the horizontal axis of the cover, which corresponds to the horizontal cup opening.
- the slope angle ⁇ 1 is measured as the angle between a line D-D, which is tangent with the slope of the annular inner sidewall 825 at the location 860 opposite the drink opening 822 (i.e., the location comprising the printed text 852 ), and a line H-H that is parallel with a horizontal axis of the cover 805 .
- the slope angle ⁇ 2 is measured as the angle between a line C-C, which is tangent with the slope of the annular inner sidewall 825 at the location 862 adjacent the drink opening 822 , the line H-H that is parallel with the horizontal. As shown, slope angle ⁇ 1 is less than the slope angle ⁇ 2 .
- the slope angle ⁇ 1 of the portion comprising the printed text 852 may be between about 10° and about 25°. In some examples, the slope angle may be between about 15° and about 20°, for example, about 16° or about 17°.
- the slope angle ⁇ 2 is greater than 01, such that the descent from the inner peripheral edge 824 of the annular upper ridge 820 is steeper than that on the opposing side of the cover 805 . In some examples, the slope angle ⁇ 2 may be between about 30° and about 45°. In some examples, the slope angle may be between about 38° and about 43°, for example, about 40° or about 41°.
- this configuration of a slope angle ⁇ 2 provides improved drinkability out of the drink hole. That is, the slope angle ⁇ 2 of the annular inner sidewall 825 adjacent the drink opening 822 provides a less obstructed flow path as the cup is tipped to pour fluid, which in turn allows for a smoother, less turbulent flow of fluid toward the drink opening 822 . This can provide a smoother, and more satisfactory sip for a user, and be less likely to result in an unexpected rush of fluid from the drink opening 822 , or undesired leaking or dribbling from the lid assembly 805 .
- the drink opening 822 is formed in the annular upper ridge 820 of the cover, and can be formed as a slot or hole, and be configured to allow contents within a cup to be poured through the lid assembly 805 . As shown in the side view of FIG. 10 and the cross-sectional view of FIG. 16 of the cover, the drink opening 822 is positioned in a higher location relative to the mounting portion 810 as compared to the opposing side of the cover 805 . This is a result of the annular upper ridge 820 forming an angled surface that extends along an axis B-B ( FIG.
- the annular upper ridge 820 slopes downward from the drink opening 822 toward the opposing side 860 . That is, the distance between the annular upper ridge 822 and the annular mounting portion 810 at the drink opening 822 is greater than the distance between the annular upper ridge 820 and the annular mounting portion 810 along the opposing portion 860 of the annular upper ridge 820 . Additionally, as seen in FIGS. 12 and 13 , the width of the annular upper ridge 820 (i.e., the distance between the outer peripheral edge 823 and the inner peripheral edge 824 ) is greater at the drink opening 822 as compared to the location 860 opposite the drink opening. This sloped upper ridge 820 configuration may provide an aesthetic appearance, and it may also allow the annular inner sidewall 825 to achieve a desired slope or angle at which to present the printed text 852 .
- the cap 807 includes a main body 850 that fits within the interior portion 835 of the cover 805 .
- the cap 807 has an outer perimeter 851 with a shape that corresponds with the shape of the outer periphery 951 of the interior portion 835 of the cover. In this way, when the cap 807 is attached to the cover 805 , the outer periphery 951 of the cover and the outer perimeter 851 of the cap form a single visible line, as opposed to two separate lines, thereby offering a cleaner and more aesthetically pleasing appearance. This is shown, for example, in the assembled lid assembly 800 of FIG. 8 .
- the cap 807 and the cover 805 can be formed from a common sheet of material, and will thus have a common thickness.
- the cap 807 and cover 805 can be formed from different sheets of material, and may be formed from different materials altogether. This will allow the cap 807 and the cover 805 to have different thicknesses, as necessary to achieve different objectives. For instance, in some situations, it may be beneficial to provide a cover 805 that is formed from a thicker base material so as to provide greater structural stability, whereas the cap 807 can be formed from a thinner material to allow for greater flexibility or movement of the flap 840 , for example. In other situations, the opposite may be more valuable. For instance, it may be useful in some situations to provide a cover of a thinner material, to allow the cover greater flexibility to attach or connect to a particular cup. Forming the two components from separate sheets of material allows for flexibility in the design of both components.
- the flap 840 is pivotally connected to the main body 850 of the cap 807 at a hinge 842 .
- the flap 840 pivots between the open and closed positions about the hinge 842 .
- a plug 845 is arranged at an end of the flap 840 and is configured to fit within the drink opening 822 of the cover 805 in a closed position, thereby closing and/or sealing the drink opening.
- the flap 840 may also include a tab 843 extending from a distal end of the flap 840 to facilitate gripping of the flap. When the flap 840 is in the closed position, the tab 843 may extend beyond the outer peripheral edge 823 of the upper ridge 820 of the cover 805 .
- the tab 843 provides a gripping surface that helps a user to grasp or flick the flap 840 and move it between open and closed positions.
- the cap 807 includes a main body 850 that fits within the interior portion 835 of the cover 805 .
- the cap 807 has an outer perimeter 851 that has a shape that corresponds with the shape of the outer periphery 951 of the interior portion 835 of the cover. In this way, when the cap 807 is attached to the cover 805 , the outer periphery 951 of the cover and the outer perimeter 851 of the cap form a single visible line, as opposed to two separate lines, thereby offering a cleaner and more aesthetically pleasing appearance.
- the interior portion 835 of the cover 805 covers the area defined within the tapered sidewalls 825 .
- the interior portion 835 defines an upper surface 902 , a groove 905 a , and a well 910 a .
- the cap 807 is configured to fit snugly over the interior portion 835 of the cover and has many of the same features of the interior portion 835 of the cover 805 so that the cap 807 nests over the interior portion 835 .
- the cap 807 includes an upper surface 870 that generally covers the interior portion 835 of the cover 807 .
- the main body 850 of the cap 807 is defined by an outer periphery 851 that corresponds with the shape of the outer periphery 951 of the interior surface 835 of the cover 805 .
- the cap 807 also includes a corresponding groove 805 b that is configured to nest within the groove 805 a in the cover 805 , and a well 910 b configured to nest within the well 910 a of the cover 805 .
- the grooves 905 ab generally extend around the periphery of the interior portion 835 of the cover 805 and the cap 807 , respectively, and terminate at opposite sidewalls of the respective wells 910 ab .
- the groove 905 a in the cover 805 may have a depth of about 1 ⁇ 8′′ relative to the upper surface 902 , and an interior shape configured to complement the corresponding outside shape of the groove 905 b of the cap 807 .
- the depth of the groove is merely exemplary and may be adjusted as necessary. More specifically, when viewed from below (see FIG. 11 ), the groove 905 a corresponds to a ridge or protrusion 906 that extends below the cap 807 .
- the interior sidewalls of the groove 905 a of the cover 805 may have a negative draft angle of about 3 to 7 degrees that match corresponding positive draft angles of the ridge. Other draft angles may be suitable. While the illustrated grooves 905 ab extend around most of the respective peripheries, it is understood that the grooves 905 ab may extend to a lesser amount or that the grooves 905 ab may not extend by the same amount. For example, the groove 905 a in the cover 805 may extend around the periphery as illustrated, while the groove 905 b in the cap 807 may extend around the cap 807 to a lesser degree, or be formed of segmented sections that fit within the groove 805 a of the cover 805 . Other configurations are contemplated.
- the respective wells 910 ab have a width and depth sized to receive the flap 840 of the cover 807 .
- a second post 915 b extends upwardly from the bottom surface of the well 910 b defined in the cap 807 . When viewed from the bottom (see FIG. 11 ), the inner side of the second post 915 b forms a cavity 916 that is configured to receive and form a friction fit with the first post 915 a on the cover 805 .
- the second post 915 b is also configured to fit within a cavity defined the backside of the plug 845 (see FIG. 14 ) disposed at the end of the flap 840 to secure the flap 840 in an open position.
- the cover 805 may define a corresponding protrusion 915 a configured to nest within the protrusion 915 b of the cap 807 .
- the centralized location of the post 915 a on the cover and the corresponding second post 915 b on the cap helps secure the cap 807 to the cover 805 , as it adds another friction fitting that holds and secures the cap 807 on the cover 805 .
- This added frictional support can inhibit the cap 807 from detaching from the cover 805 as a result of tension forces applied from the flap 804 to the cap 807 after periodic movement of the flap 840 between open and closed positions.
- the interior portion 835 of the cover 505 also includes a small opening 917 a to facilitate equalization of pressure within the drink cup when the lid assembly 800 is attached to the cup.
- a corresponding opening 917 b may be provided in the cap 807 .
- the respective openings 917 ab may be aligned to provide an unobstructed passage between the space within the cup and the atmosphere outside of the cup. In other configurations, the respective openings 917 ab may be offset from one another (e.g., on opposing sides of the lid assembly 800 as shown in FIG. 9 ), to provide an impeded flow path between the openings 917 ab to inhibit the unwanted leakage of fluid from the cup through the openings 917 ab.
- the cap 807 includes printed text 852 on an upper surface 870 of the cap.
- the printed text 852 includes branding text 852 b and informational text 852 c that identifies the particular cup size that the lid assembly 800 is designed to cooperate with (e.g., 20 or 24 ounce cups).
- the printed text portions 852 bc on the cap 807 are formed as deformations in the material forming the cap 805 .
- the flap 840 will operate between open and closed positions essentially within one half (i.e., the drinking half) of the lid assembly 800 . This allows for the printed text 852 on the side of the cap opposite the drink opening 822 to remain generally uncovered and unobstructed from view in both the open and closed configuration of the flap 840 .
- a flap that is relatively short in particular, with respect to lids that place a post away from the center, in a location on the lid opposite the drink opening.
- Users may find that a shorter flap 840 is easier to toggle between the open and closed positions because the distance between the two positions is relatively short. For example, a user may be able to move the flap 840 with a simple flick of a finger on a hand that is holding the cup. That is, the user may be able to move the flap 840 without having to either let go of the cup, and without involving the use of a second hand.
- the shorter flap will be less likely to interfere with a user during the drinking process. That is, a longer flap, if left unsecured may flop down on top of a user's nose as a user tilts the cup to drink a beverage, which can be annoying and distracting to the user.
- the shorter flap 840 on the other hand, even if left unsecured, may be too short to significantly interfere with a user's face, even if the flap 840 is unsecured.
- lid assemblies described in this application are stackable with other similar lid assemblies.
- lid assembly 800 may nest with other similar lid assemblies 800 such that multiple lid assemblies 800 nested together occupy less space than the individual un-nested lid assemblies 800 would occupy collectively. This can be particularly useful for packaging, shipping, and presenting the lid assemblies prior to installation on a cup.
- the tab 843 extending from the flap 840 of the cap 807 can affect the stackability of the lid assemblies 800 .
- the outer annular sidewall 815 of another stacked lid may inhibit the ability of the lid assemblies 800 to nest with one another, thereby resulting in a nested stack of lid assemblies 800 that occupies more space than necessary.
- the outer annular sidewall 815 of the lid assembly at the drink opening 822 includes a rounded, or parabolic shaped configuration, as shown in the cross-sectional view of the cover 805 in FIG. 16 .
- This rounded configuration allows a tab 843 of the flap 840 that extends a distance from the outer peripheral edge 823 of the upper ridge 820 to bend downward and tuck between the outer annular sidewalls 815 of two nested lid assemblies without significantly affecting stackability.

Abstract
Description
- This application claims the priority benefit of U.S. provisional application No. 62/419,306, filed Nov. 8, 2016, titled “Cup Lid With Reclosable Cap,” the contents of which is hereby incorporated by reference in its entirety.
- Cup lids can be used to seal the top opening of a beverage container. For example, vendors often provide disposable cup lids with cups or other containers that contain drinks such as coffee, tea, soda, etc. Such cup lids include an annular mounting portion that allows the lid to attach and/or seal with the cup. The lids have an opening or spout that allows users to drink or otherwise pour fluid from the cup or container while the lid is in place.
- Some cup lids have an integrated closure member that facilitates closing or covering of the opening or spout. The closure members can help inhibit spillage or undesired leaking through the opening when the opening is not in use. For example, some lids have an arm with a tab at a distal end that extends from the periphery of the lid. A user may flex the arm to insert the tab into the drink opening of the lid, thereby closing or plugging the opening.
- Some cup lids have printed text that displays promotional, warning, or other types of information. For example, some cup lids will include printed text that warns consumers about the temperature of the contents of the cup, or that provides branding information in the form of logos or product names associated with the beverage. Some cup lids will also include other information relating to the size of the cup, or whether or not the lid is recyclable. Users may find this printed text difficult to read for various reasons. For example, the printed text may be formed via a deformation in the lid itself, and thus have the same color as the surrounding portion of the lid. As a result, the text may not be readily discernable in certain light or at certain viewing angles. Further, the arm or sealing mechanisms may lie over the text, thereby obscuring, hiding, or otherwise making the text difficult to read.
- In one form according to the present invention, this application discloses and describes a lid assembly that includes a cover and a cap. The cover is configured to attach to a cup opening. The cover includes an annular mounting portion that secures and/or seals the cover to a top rim of the cup. The cover also has an annular upper ridge with a drink opening that allows fluid contents of the cup to be poured from the cup. An annular outer sidewall extends upward from the mounting portion to an outer peripheral edge of the annular upper ridge. The cover also has an annular inner sidewall circumscribing an interior portion. The annular inner sidewall has a surface that slopes downward and inward from the annular upper ridge to the interior portion. The cap is attachable to the cover and includes a main body and a flap that pivotally extends from the main body. The flap has a hinge and a plug at an end of the flap. The plug can be inserted into the drink opening to form a seal that inhibits fluid within the container from leaking out of the drink opening. In some aspects, the cover has printed text on the sloped surface of the annular inner sidewall. The printed text extends across a location of the annular inner sidewall that is opposite the drink opening. In additional and/or alternative aspects, the interior portion of the cover includes a first post and the main body of the cap includes a corresponding second post defining a cavity on the underside of the cap. The first post is configured to fit within the second post with a friction fit to help secure the cap to the cover. The second post is also configured to form a securable connection with a cavity defined on an underside of the plug. In this way, the flap can be pulled back to the second post and secured in place when it is not sealing the drink opening.
- In another aspect, a lid assembly for covering an opening of a cup includes a cover configured to cover the opening of the cup and a cap configured to be selectably attached to the cover. The cover includes an annular mounting portion configured to secure the cover to a top rim of the cup, an annular sidewall that extends upwardly from the mounting portion to an outer periphery of an upper ridge of the cover, and a drink opening defined in the upper ridge. A tapered sidewall extends around an interior portion of the cover. The tapered sidewall includes one or more regions at which the tapered sidewall tapers gradually downward from an inner periphery of the ridge towards respective one or more inner vertical surfaces of the interior portion. An interior surface of the cover extends between respective lower edges of the vertical surfaces to cover substantially the area of the interior portion of the cover. The cap includes a main body configured to be positioned over and to cover the interior surface of the interior portion of the cover. The cap also includes a flap that is pivotally connected to the main body. The cap includes a plug at an end opposite a hinge or pivot end configured to be inserted within the drink opening and to seal the drink opening.

The lid assembly is arranged to form a securable attachment to the opening of the cup, such that the lid remains in place on the cup when the cup is tipped to dispense fluids. The lid assembly may form a tight seal that inhibits fluid from within the cup from leaking from any undesirable locations, namely, from any locations other than through the drink opening.
- The lid assembly generally comprises a cover component and a cap component that are separably attachable to one another. The cover component generally covers the top of a cup, and includes a drink opening through which a user may drink or otherwise pour out the cup's contents. The cap component attaches to the cover component and allows the drink opening to be closed or sealed. More specifically, the cap component includes a flap and a plug that is pivotable between open and closed positions so that the drink opening can be closed and/or sealed to inhibit unwanted dripping, leaking, or spilling of the cup's contents through the drink opening, and to help improve the thermal insulation properties of the lid assembly. The cap may be an optional member. The cap may be configured to be secured to or released from the cover by a user, such as a consumer.
-
FIG. 1 illustrates a perspective view of one example of alid assembly 100 for covering a drink cup. Thelid assembly 100 includes acover 105 that is configured to attach to the cup and may be used to substantially seal the contents therein within the cup. Thelid assembly 100 also includes acap 205 that may be separately attached to thecover 105. - The
cover 105 includes anannular mounting portion 110 configured to secure thecover 105 to a top rim of the cup. In some forms, the annular mounting 110 portion forms a seal that inhibits fluid from within the cup from spilling or otherwise leaking from the cup around the top rim. Anannular sidewall 115 extends upwardly from the mountingportion 110 to an outer periphery of anupper ridge 120 of thecover 105. Adrink opening 122 is defined in theupper ridge 120 as shown inFIG. 2 . - As illustrated in
FIG. 2 , a tapered sidewall 125 extends around the interior portion of thecover 105. The sidewall 125 includes a first set of regions where the sidewall 125 tapers gradually downward from the inner periphery of theridge 120 towards a first set ofvertical surfaces 130. That is, each region tapers towards a differentvertical surface 130. In some implementations, the sidewall 125 also includes a set ofledge regions 127 where the sidewall continues to taper past the first set ofvertical surfaces 130 to a second set ofvertical surfaces 131. - An
interior surface 135 of the interior portion extends between lower edges of the first set ofvertical surfaces 130 to thereby substantially cover the entire area of the interior portion. In implementations that include theledge regions 127, lower edges of the second set ofvertical surfaces 131 may be separated from theinterior surface 135 by a distance to thereby define a gap or undercut 132 between lower surfaces of theledge regions 127 and theinterior surface 135. Thegap 132 width may be slightly larger than the thickness of thecap 205 to facilitate insertion of edge portions of thecap 205 into thegaps 132 below theledge regions 127. For example, the gap width may be about 0.100″. - Referring to
FIG. 3 , the cap includes amain body 210, and aflap 220 that is pivotally connected to themain body 210. Themain body 210 is configured to be positioned over and to substantially cover theinterior surface 135 of the interior portion of thecover 105. While a solid surface is illustrated, it is understood that themain body 210 does not generally play a role in sealing the contents within the cup. Therefore, one or more openings for decorative purposes, to reduce material usage, etc., may be provided in themain body 210. - In some implementations, the
main body 210 of thecap 205 may define aprotruded surface 215. In this regard, theinterior surface 135 of thecover 105 may define a complementaryindented surface 140 configured to receive theprotruded surface 215. Theprotruded surface 215 and theindented surface 140 cooperate to control alignment of thecap 205 within the interior portion of thecover 105. - The
flap 220 is pivotally connected to themain body 210. In some implementations, theflap 220 is connected via a resilient portion or hinge 230. Theresilient portion 230 may have a generally curved cross-section and may be sized to facilitate opening and closing of theflap 220 for a repeated number of times without breaking. In this regard, theresilient portion 230 may be configured to extend somewhat below a plane within which themain body 210 lies. The distance by which theresilient portion 230 is below themain body 210 may be related to the radius of the curved section. To facilitate flush mounting of themain body 210 within the interior portion of thecover 105, theinterior surface 135 of thecover 105 may define anindentation 145 with a depth that at least matches the distance by which theresilient portion 230 extends below themain body 210 to prevent substantial interference between theinterior surface 135 of thecover 105 and theresilient portion 230 of theflap 220. - At the opposite end of the
flap 220 from the pivot end, theflap 220 includes aplug 225 configured to be inserted within thedrink opening 122 and to seal thedrink opening 122 when theflap 220 is placed in the closed configuration, as illustrated inFIG. 1 . Theflap 220 may also include a handle ortab portion 230 arranged above theplug 225. Thehandle 230 may be pinched between a user's thumb and forefinger to facilitate removal of theplug 225 from thedrink opening 122. - In one implementation, the gripping portion or handle 243 is also arranged relative to the
protrusion 215 in themain body 210, such that when theflap 220 is placed in the fully open position (seeFIG. 4 ), thehandle 230 enters the cavity defined by theprotrusion 215 and engages an inside edge of theprotrusion 215 to thereby retain theflap 220 in the open configuration. Other methods known in the art may be utilized to secure theflap 220 in the open configuration. - The
cover 105 andcap 205 may come pre-assembled or may be provided separately. When provided separately, a user may insert thecap 205 into the interior of thecover 105. In implementations without theledge regions 127, the disk may be sized to provide a friction fit against the innervertical surfaces 130 at which the first set of regions of the tapered sidewall 125 terminate to thereby secure thecap 205 within the interior portion of thecover 105. - In implementations that include the
ledge regions 127, the diameter of the main body may be sized so that the edges of themain body 210 of thecap 205 resiliently snap into thegap 132 between the lower surfaces of theledge regions 127 and theinterior surface 210 of thecover 105 when thecap 205 is attached to the cover. The angle at which the tapered sidewall 125 tapers may be adjusted to allow thedisk portion 210 to slide more easily into the fully sealed position. -
FIG. 5 illustrates a perspective view of asecond lid assembly 500 embodiment for covering an opening of a drink cup. Thelid assembly 500 includes acover 505 that is configured to attach to the top rim of the cup and to substantially seal the contents therein within the cup. Thelid assembly 500 also includes acap 507 that may be separably attached to thecover 505. Thelid assembly 500 and related components are similar in structure to thelid assembly 800 and related component shown inFIGS. 8-16 , however, thelid assembly 500 does not include printed text, such as a warning label, trademark, or logo. It should be appreciated that the various features and structural components of thelid assembly 500 and thelid assembly 800, including the printed text, are interchangeable with one another. For instance, the embodiments of thelid assembly 500 shown and described with respect toFIGS. 5-7 could be modified to include printed text, as with the embodiments shown and described inFIGS. 8-15 . - Referring to
FIGS. 6A and 6B , the lid assembly generally includes many of the features described above with reference to thefirst lid assembly 100 embodiment. For example, thecover 505 of thelid assembly 500 includes anannular mounting portion 110, anannular sidewall 115 that extends upwardly from the mountingportion 110 to an outer periphery of anupper ridge 120 of thecover 105, and adrink opening 122 that is defined in theupper ridge 120. A tapered sidewall 525 (shown inFIG. 5 ) extends between theupper ridge 120 and aninterior portion 635. - The
cap 507 includes amain body 650 that fits over theinterior portion 635 of thecover 505. Aflap 220 is pivotally connected to themain body 650 via ahinge 642. Aplug 225 is arranged at an end of theflap 220 and is sized and configured to be received within thedrink opening 122 of thecover 505 with a friction fit. - The
interior portion 635 of thecover 505 extends within the area defined by theinterior edges 551 of the taperedsidewalls 525. Theinterior portion 635 includes anupper surface 602, agroove 605 a, a recessed well 610 a, and a recessed surface 629. Thecap 507 is configured to fit snuggly over theinterior portion 635 of the cover and has many of the same features so that thecap 507 nests over theinterior portion 635. For example, thecap 507 includes anupper surface 670 that generally covers theinterior portion 635 of thecover 507, agroove 605 b which forms a protrusion extending from a bottom side of thecap 507 configured to nest within thegroove 605 a in thecover 505, and a well 610 b configured to nest within the well 610 a of thecover 505. - The grooves 605 ab (i.e. 605 a and 605 b) generally extend around the periphery of the
interior portion 635 of thecover 505 and thecap 507, respectively, and terminate at or adjacent opposite sidewalls of therespective wells 610 ab. Thegroove 605 a in thecover 505 has a depth of about ⅛″, relative to theupper surface 602, and an interior shape configured to complement the corresponding outside shape of thegroove 605 b of thecap 507. The depth of the grooves is merely exemplary and may be adjusted as necessary. More specifically, when viewed from below, thegroove 605 a corresponds to a protrusion 606 (see the cross section ofFIG. 7 ) or ridge that extends below thecap 507. The interior sidewalls of thegroove 605 a of thecover 505 may have a negative draft angle of about 3 to 7 degrees that match corresponding positive draft angles of the protrusion 606. Other draft angles may be suitable. While the illustrated grooves 605 ab extend around most of the respective peripheries, it is understood that the grooves 605 ab may extend to a lesser amount or that the grooves 605 ab may not extend by the same amount. For example, thegroove 605 a in thecover 505 may extend around the periphery as illustrated, while thegroove 605 b in thecap 507 may extend around thecap 507 to a lesser degree, or be formed of segmented sections that fit within thegroove 605 a of thecover 505. Other configurations are contemplated. - The
respective wells 610 ab have a width and depth sized to receive theflap 220 of thecover 507. A protrusion or post 615 b having a racetrack shape extends upwardly from the bottom surface of the well 610 b defined in thecap 507. The protrusion 615 b is configured to fit within arecess 226 formed in the backside of theplug 225 disposed at the end of theflap 220 to secure theflap 220 in an open position. In some implementations, the arrangement may be reversed such that thecover 505 may define a corresponding recess configured to receive a protrusion extending from the bottom side of thecap 507. - A small opening 617 a is defined in the
interior portion 635 of thecover 505 to facilitate equalization of pressure within the drink cup when thelid assembly 500 is attached to the cup. A corresponding opening 617 b may be provided in thecap 507. Therespective openings 617 ab may be aligned to provide an unobstructed passage between the space within the cup and the atmosphere outside of the cup. - In some implementations, a recessed
surface 620 may be defined in theinterior portion 635 of thecover 505. The opening 617 a may be defined within the recessedsurface 620. The recessedsurface 620 may be recessed below theupper surface 602 of the interior portion of thecover 505 by a depth of about 1/16″ of a different depth. - As illustrated in
FIG. 7 , this results in the formation of acavity 705 betweencap 507 and thecover 505 when the two are assembled. Thecavity 705 facilitates relaxation of the alignment requirements between therespective openings 617 ab by providing a conduit between theopenings 617 ab. Moreover, theopenings 617 ab may be spaced laterally apart from one another to minimize fluid leakage through theopenings 617 ab that may otherwise occur when the twoopenings 617 ab are aligned. - While the
lid 100 has been described with reference to certain embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope. For example, in the first lid assembly embodiment, in implementations that do not include theledge regions 127, the set of regions that terminate at the first set ofvertical sidewalls 130 may form one continuous region and the first set ofvertical sidewalls 130 may be one continuous sidewall that generally extends around the interior portion of the cover. In implementations that include theledge regions 127, the main body may not be sized to provide a friction fit against the first set ofvertical surfaces 130. That is, themain body 210 may be held in place via the gap/undercut 132 below theledge portions 127 alone. Of course, in the alternative, themain body 210 may also be sized to provide a friction fit against the first set ofvertical surfaces 130. - The resilient portion of the
flap 220 may be arranged above themain body 210 which may facilitate elimination of theindentation 145 in theinterior surface 135 of thecover 105. - The lid may be made from a variety of materials including polystyrene, polypropylene, paper, and may include fillers such as talc or calcium. Paper materials may include paper from tree, sugarcane bagasse, fiber, etc. Other materials known to those skilled in the art, such as biodegradable and/or compostable materials, may also be utilized. In some implementations, the
cover 105 andcap 205 may be made from different materials and have the same or different thickness. For example, the cap and cover may have a thickness of about 0.015″. Alternatively, one of the cap and cover may have a thickness of about 0.012″, and the other may have a thickness of about 0.015″. Thecover 105 andcap 205 may be manufactured via thermoforming, injection molded, pulp molded, etc. - Other alignment features (i.e., protrusions in the cap and indentations in the cover, or vise-versa) may be provided. Alternatively, the shape of the main body and the sidewall at which the tapered sidewall of the cover terminates may be keyed to align the main body within the interior portion of the cover.
- In some implementations, the cap may be secured to the cover via an adhesive, friction welding, etc. In this regard, the
main body 210 may have a diameter smaller than that of the tapered sidewall 125 at an inner edge thereof. - In yet other implementations, the
main body 210 may include a retention protrusion configured to maintain the flap in the open configuration. - Some examples of lid assemblies described herein can be used to improve the manner that readable indicia, or printed text, is displayed on the lid assembly. That is, some of the lids are configured and arranged so that the printed text is easier for a user to identify, recognize, and read. Throughout this application, the terms “readable indicia” or “printed text” refer to text provided on the lid or its components in a recognizable format. The “printed text” or “readable indicia” can be printed with ink or paint, or it can be formed as a deformation in the lid material, for example, by being stamped, etched, engraved, embossed, or molded into the material that forms the lid or its components. The printed text or readable indicia may include letters, numbers and punctuation, but it can also include other graphics such as logos, symbols, shapes, designs, patterns, images, bar codes, Braille patterns, and the like. The terms “printed text” and “readable indicia” as used throughout this application are meant to be interchangeable with one another.
- The printed text can be arranged in a manner so that a user drinking from the cup can readily recognize and read the printed text on the lid assembly. For example, the printed text is arranged on a sloped surface that is angled toward a location that generally corresponds with an eye level of a user holding or drinking from the cup. Providing the printed text on a sloped surface can help improve the visibility of the printed text by providing a more direct line of sight with a cup-holder's eyes, and by mitigating reflections of light off the surface of the lid. In some aspects, the printed text is provided as a deformation in the lid material, meaning that the text itself is merely a contoured texture and does not necessarily stand out by way of contrasting colors or shading. In these aspects, reflections, viewing angles, and other factors can diminish a user's ability to read or recognize the printed text. By providing the printed text on a sloped or angled surface, the printed text may be closer to perpendicular with a cup user's line of sight. Not only can this help make the printed text easier to read, it can also make the printed text stand out more and draw the attention of a cup user.
- Further, providing the printed text on a sloped surface can also help improve the clarity of the printed text itself. For instance, where printed text is formed by a stamping or molding process, producing the printed text on a sloped surface can mitigate, inhibit, or reduce undesirable ghosting effects or other issues that can result from the molding or stamping processes, which can make the printed text blurrier or otherwise more difficult to read.
- Some implementations provide the printed text in a manner so that the printed text is not covered or obstructed by other objects, such as a flap or a sealing mechanism. This can be accomplished by arranging a flap or sealing mechanism so that it leaves a portion of the lid assembly uncovered, or unobstructed in both an open or closed position. For example, a lid may provide for unobstructed text by arranging a securing post in or near the center of the lid assembly, so that the flap secures to the centralized post without covering or resting over at least a portion of the lid assembly on an opposite side of the post. The text on the lid assembly opposite the flap will therefore remain uncovered and readable at all times, regardless of whether the flap is in an open or closed position.
- In some examples of the described lid assemblies, the shape of the cover and cap components are configured to provide a more aesthetic appearance. For example, some examples configure the shape of the cap, or the shape of the outer periphery of the cap so that it corresponds with the shape of certain components or portions of the cover. In particular, the shape of the outer perimeter of the cap may be designed to correspond with the outer periphery of an interior portion of the cover, so that the peripheral edge of the cap generally aligns with the outer periphery of the interior portion when installed on the lid assembly. Matching these shapes can align two edges so that they appear as a single edge to a cup user, and give the impression that the lid assembly is a single piece, rather than two separate pieces. This single edge look may appear less busy, sleeker, and otherwise more visually appealing to consumers. Matching the shape of the cap and interior portion of the cover also provides a relatively large area on the cap in which printed text may be provided, such as a trademark, logo, or other information, as described in more detail below.
- Some features described herein also allow for an improved connection between the separate cap and cover components of the lid assembly. For instance, some examples utilize a centralized post in the cover, and a corresponding cavity in the cap that is designed to form a tight, friction fit with the centralized post. This post can improve the securement of the cap to the cover, and inhibit unwanted lifting or separation that can result from repeated lifting and movement of the flap between the open and closed positions. In some aspects, the arrangement of the centralized post allows for more freedom in the arrangement between the grooves of the cover and cap, such that the cap can take on different shapes or attach to the cover in different ways while still maintaining a firm fit onto the
cover 505. Further, in some aspects, the arrangement of the centralized post can replace the groove configuration altogether, such that the post is the only friction connection holding the cap to the cover. - The embodiments shown in
FIGS. 8-16 present examples of a lid assembly that utilizes many of the features described above.FIG. 8 illustrates a perspective view of an example of alid assembly 800 comprising acover 805 and acap 807 with printed text on thecover 805 and thecap 807. Thelid assembly 800 inFIG. 8 is shown in an assembled state, namely, with thecap 807 secured to thecover 805.FIGS. 9, 10, and 11 show exploded top perspective, side, and bottom perspective views, respectively, of thelid assembly 800, that is, with thecap 807 removed from thecover 805. Thecap 807 inFIGS. 8-11 is shown with aflap 840 that is in an open position, namely, theflap 840 is away from, and not closing off thedrink opening 822. As shown inFIGS. 8-11 , theflap 840 is held in the open position by securing the plug 845 (shown inFIG. 14 ) to the post 915 b.FIGS. 12 and 13 show a perspective and top view, respectively, of thecover 805 component by itself, removed from thecap 807.FIG. 14 shows a top view of thecap 807 by itself, removed from thecover 805. Thecap 807 ofFIG. 14 is shown in a closed state, that is, with theflap 840 extending away from themain body 850 of thecap 805, such that theplug 845 on the end of theflap 840 could be inserted into and seal thedrink opening 822.FIGS. 15 and 16 show side, cross-sectional views of thecap 807 in an open configuration, and thecover 805, respectively. - The
lid assembly 800 ofFIGS. 8-16 may be similar or even the same as thelid assembly 500 shown and described with respect toFIGS. 5-7 , with the exception thatlid assembly 800 includes printedtext 852 formed into thecover 805 andcap 807 components. The printedtext 852 is shown as a deformation in the material that forms thecover 805 orcap 807. That is, the printedtext 852 is imprinted into the material by way of an indentation or engraving. This can be formed via a variety of different techniques, including, for example, by molding, stamping, thermosetting, or other techniques. The printedtext 852 includes warningtext 852 a that informs users of potential hazards associated with the cup or the contents therein. The printedtext 852 also includesbranding information 852 b that identifies or promotes products or brands, such as that of the lid manufacturer, the cup manufacturer, or the provider of the contents within the cup (e.g., a particular restaurant or coffee shop). Thebranding information 852 b can include trade names or other non-alphanumeric graphics such as logos, symbols, or other images. The printedtext 852 also includesinformative text 852 c that provides useful information relating to the lid, cup, or contents. For instance, theinformative text 852 c can be used to identify the size or volume of the cup, instructions on how to assemble or manipulate the lid or components, information about the contents served in the cup, the material that the cup or lid is formed from, whether the cup and/or the lid is recyclable, production or batch information associated with the lid or the cup, or patent or other intellectual property markings, to name but a few examples. - Referring to
FIGS. 12 and 13 , thelid assembly 800 generally includes many of the features described above with reference tolid assembly 100 andlid assembly 500. For example, thecover 805 of thelid assembly 800 includes anannular mounting portion 810, an annularouter sidewall 815 that extends upwardly from the mountingportion 810 to an outerperipheral edge 823 of the annularupper ridge 820 of thecover 805, and adrink opening 822 that is defined in theupper ridge 820. An annularinner sidewall 825 extends between the innerperipheral edge 824 of theupper ridge 820 and theinterior portion 835, and intersects theinterior portion 835 at anouter periphery 951, which at least partially defines the shape of theinterior portion 835. The annularinner sidewall 825 is sloped downward and inward between the annularupper ridge 820 and theinterior portion 835. - The annular
inner sidewall 825 includes printedtext 852 along the sloped surface on aside 860 of the lid opposite thedrink opening 822. Providing the printedtext 852 in this location and on a sloped surface allows the printed text to be displayed in a manner that is recognizable and readable to a user as a user holds and/or drinks from the cup. The angle of the sloped surface can vary depending on a variety of factors including, but not limited to, the size of the cup and/or lid, the size of the printed text, and the radius of curvature of the annularinner sidewall 825. - The slope, or angle of the annular
inner sidewall 825 can vary among locations about the periphery of thecover 805. For instance, the slope angle of the portion of the annular inner sidewall comprising printedtext 860 may differ from the slope angle of the annular inner sidewall adjacent thedrink opening 862, which can be seen from the cross-sectional view of thecover 805 ofFIG. 16 . The slope angle θ at a particular point is defined by the angle formed between an axis tangent to the annular inner sidewall at the particular point and the horizontal axis of the cover, which corresponds to the horizontal cup opening. The slope angle θ1 is measured as the angle between a line D-D, which is tangent with the slope of the annularinner sidewall 825 at thelocation 860 opposite the drink opening 822 (i.e., the location comprising the printed text 852), and a line H-H that is parallel with a horizontal axis of thecover 805. The slope angle θ2 is measured as the angle between a line C-C, which is tangent with the slope of the annularinner sidewall 825 at thelocation 862 adjacent thedrink opening 822, the line H-H that is parallel with the horizontal. As shown, slope angle θ1 is less than the slope angle θ2. In some examples, the slope angle θ1 of the portion comprising the printedtext 852 may be between about 10° and about 25°. In some examples, the slope angle may be between about 15° and about 20°, for example, about 16° or about 17°. On the opposite side of thecover 805, the slope angle θ2 is greater than 01, such that the descent from the innerperipheral edge 824 of the annularupper ridge 820 is steeper than that on the opposing side of thecover 805. In some examples, the slope angle θ2 may be between about 30° and about 45°. In some examples, the slope angle may be between about 38° and about 43°, for example, about 40° or about 41°. It is believed that this configuration of a slope angle θ2 provides improved drinkability out of the drink hole. That is, the slope angle θ2 of the annularinner sidewall 825 adjacent thedrink opening 822 provides a less obstructed flow path as the cup is tipped to pour fluid, which in turn allows for a smoother, less turbulent flow of fluid toward thedrink opening 822. This can provide a smoother, and more satisfactory sip for a user, and be less likely to result in an unexpected rush of fluid from thedrink opening 822, or undesired leaking or dribbling from thelid assembly 805. - The
drink opening 822 is formed in the annularupper ridge 820 of the cover, and can be formed as a slot or hole, and be configured to allow contents within a cup to be poured through thelid assembly 805. As shown in the side view ofFIG. 10 and the cross-sectional view ofFIG. 16 of the cover, thedrink opening 822 is positioned in a higher location relative to the mountingportion 810 as compared to the opposing side of thecover 805. This is a result of the annularupper ridge 820 forming an angled surface that extends along an axis B-B (FIG. 10 ) that is angled with respect to the axis A-A of the annular mountingportion 810, such that the annularupper ridge 820 slopes downward from thedrink opening 822 toward the opposingside 860. That is, the distance between the annularupper ridge 822 and the annular mountingportion 810 at thedrink opening 822 is greater than the distance between the annularupper ridge 820 and the annular mountingportion 810 along the opposingportion 860 of the annularupper ridge 820. Additionally, as seen inFIGS. 12 and 13 , the width of the annular upper ridge 820 (i.e., the distance between the outerperipheral edge 823 and the inner peripheral edge 824) is greater at thedrink opening 822 as compared to thelocation 860 opposite the drink opening. This slopedupper ridge 820 configuration may provide an aesthetic appearance, and it may also allow the annularinner sidewall 825 to achieve a desired slope or angle at which to present the printedtext 852. - The
cap 807 includes amain body 850 that fits within theinterior portion 835 of thecover 805. Thecap 807 has anouter perimeter 851 with a shape that corresponds with the shape of theouter periphery 951 of theinterior portion 835 of the cover. In this way, when thecap 807 is attached to thecover 805, theouter periphery 951 of the cover and theouter perimeter 851 of the cap form a single visible line, as opposed to two separate lines, thereby offering a cleaner and more aesthetically pleasing appearance. This is shown, for example, in the assembledlid assembly 800 ofFIG. 8 . - In some formats, the
cap 807 and thecover 805 can be formed from a common sheet of material, and will thus have a common thickness. However, in other formats, thecap 807 and cover 805 can be formed from different sheets of material, and may be formed from different materials altogether. This will allow thecap 807 and thecover 805 to have different thicknesses, as necessary to achieve different objectives. For instance, in some situations, it may be beneficial to provide acover 805 that is formed from a thicker base material so as to provide greater structural stability, whereas thecap 807 can be formed from a thinner material to allow for greater flexibility or movement of theflap 840, for example. In other situations, the opposite may be more valuable. For instance, it may be useful in some situations to provide a cover of a thinner material, to allow the cover greater flexibility to attach or connect to a particular cup. Forming the two components from separate sheets of material allows for flexibility in the design of both components. - As shown in
FIG. 14 , theflap 840 is pivotally connected to themain body 850 of thecap 807 at ahinge 842. Theflap 840 pivots between the open and closed positions about thehinge 842. Aplug 845 is arranged at an end of theflap 840 and is configured to fit within thedrink opening 822 of thecover 805 in a closed position, thereby closing and/or sealing the drink opening. Theflap 840 may also include atab 843 extending from a distal end of theflap 840 to facilitate gripping of the flap. When theflap 840 is in the closed position, thetab 843 may extend beyond the outerperipheral edge 823 of theupper ridge 820 of thecover 805. Thetab 843 provides a gripping surface that helps a user to grasp or flick theflap 840 and move it between open and closed positions. - The
cap 807 includes amain body 850 that fits within theinterior portion 835 of thecover 805. Thecap 807 has anouter perimeter 851 that has a shape that corresponds with the shape of theouter periphery 951 of theinterior portion 835 of the cover. In this way, when thecap 807 is attached to thecover 805, theouter periphery 951 of the cover and theouter perimeter 851 of the cap form a single visible line, as opposed to two separate lines, thereby offering a cleaner and more aesthetically pleasing appearance. - The
interior portion 835 of thecover 805 covers the area defined within the taperedsidewalls 825. Theinterior portion 835 defines anupper surface 902, agroove 905 a, and a well 910 a. Thecap 807 is configured to fit snugly over theinterior portion 835 of the cover and has many of the same features of theinterior portion 835 of thecover 805 so that thecap 807 nests over theinterior portion 835. For example, thecap 807 includes anupper surface 870 that generally covers theinterior portion 835 of thecover 807. In some configurations, themain body 850 of thecap 807 is defined by anouter periphery 851 that corresponds with the shape of theouter periphery 951 of theinterior surface 835 of thecover 805. Thecap 807 also includes a corresponding groove 805 b that is configured to nest within the groove 805 a in thecover 805, and a well 910 b configured to nest within the well 910 a of thecover 805. - The grooves 905 ab generally extend around the periphery of the
interior portion 835 of thecover 805 and thecap 807, respectively, and terminate at opposite sidewalls of the respective wells 910 ab. Thegroove 905 a in thecover 805 may have a depth of about ⅛″ relative to theupper surface 902, and an interior shape configured to complement the corresponding outside shape of thegroove 905 b of thecap 807. The depth of the groove is merely exemplary and may be adjusted as necessary. More specifically, when viewed from below (seeFIG. 11 ), thegroove 905 a corresponds to a ridge orprotrusion 906 that extends below thecap 807. The interior sidewalls of thegroove 905 a of thecover 805 may have a negative draft angle of about 3 to 7 degrees that match corresponding positive draft angles of the ridge. Other draft angles may be suitable. While the illustrated grooves 905 ab extend around most of the respective peripheries, it is understood that the grooves 905 ab may extend to a lesser amount or that the grooves 905 ab may not extend by the same amount. For example, thegroove 905 a in thecover 805 may extend around the periphery as illustrated, while thegroove 905 b in thecap 807 may extend around thecap 807 to a lesser degree, or be formed of segmented sections that fit within the groove 805 a of thecover 805. Other configurations are contemplated. - The respective wells 910 ab have a width and depth sized to receive the
flap 840 of thecover 807. A second post 915 b extends upwardly from the bottom surface of the well 910 b defined in thecap 807. When viewed from the bottom (seeFIG. 11 ), the inner side of the second post 915 b forms acavity 916 that is configured to receive and form a friction fit with thefirst post 915 a on thecover 805. The second post 915 b is also configured to fit within a cavity defined the backside of the plug 845 (seeFIG. 14 ) disposed at the end of theflap 840 to secure theflap 840 in an open position. In some implementations, thecover 805 may define acorresponding protrusion 915 a configured to nest within the protrusion 915 b of thecap 807. The centralized location of thepost 915 a on the cover and the corresponding second post 915 b on the cap helps secure thecap 807 to thecover 805, as it adds another friction fitting that holds and secures thecap 807 on thecover 805. This added frictional support can inhibit thecap 807 from detaching from thecover 805 as a result of tension forces applied from the flap 804 to thecap 807 after periodic movement of theflap 840 between open and closed positions. - The
interior portion 835 of thecover 505 also includes asmall opening 917 a to facilitate equalization of pressure within the drink cup when thelid assembly 800 is attached to the cup. A corresponding opening 917 b may be provided in thecap 807. The respective openings 917 ab may be aligned to provide an unobstructed passage between the space within the cup and the atmosphere outside of the cup. In other configurations, the respective openings 917 ab may be offset from one another (e.g., on opposing sides of thelid assembly 800 as shown inFIG. 9 ), to provide an impeded flow path between the openings 917 ab to inhibit the unwanted leakage of fluid from the cup through the openings 917 ab. - As seen in
FIGS. 8 and 9, and 14 , thecap 807 includes printedtext 852 on anupper surface 870 of the cap. The printedtext 852 includesbranding text 852 b andinformational text 852 c that identifies the particular cup size that thelid assembly 800 is designed to cooperate with (e.g., 20 or 24 ounce cups). Like thewarning text 852 a on the cover, the printedtext portions 852 bc on thecap 807 are formed as deformations in the material forming thecap 805. Because the posts 915 ab are positioned in a centralized location (e.g., positioned in a middle area of the lid assembly, positioned on or about the center) with respect to the lid assembly, theflap 840 will operate between open and closed positions essentially within one half (i.e., the drinking half) of thelid assembly 800. This allows for the printedtext 852 on the side of the cap opposite thedrink opening 822 to remain generally uncovered and unobstructed from view in both the open and closed configuration of theflap 840. Further, providing the centralized post 915 ab in a central location (e.g., at the center of the lid assembly itself), allows for a flap that is relatively short, in particular, with respect to lids that place a post away from the center, in a location on the lid opposite the drink opening. Users may find that ashorter flap 840 is easier to toggle between the open and closed positions because the distance between the two positions is relatively short. For example, a user may be able to move theflap 840 with a simple flick of a finger on a hand that is holding the cup. That is, the user may be able to move theflap 840 without having to either let go of the cup, and without involving the use of a second hand. This can be particularly useful to users that do not have a second hand available (e.g., users drinking a beverage while driving, or holding other objects, etc.). Moreover, the shorter flap will be less likely to interfere with a user during the drinking process. That is, a longer flap, if left unsecured may flop down on top of a user's nose as a user tilts the cup to drink a beverage, which can be annoying and distracting to the user. Theshorter flap 840, on the other hand, even if left unsecured, may be too short to significantly interfere with a user's face, even if theflap 840 is unsecured. - In some implementations, the lid assemblies described in this application are stackable with other similar lid assemblies. For example,
lid assembly 800 may nest with othersimilar lid assemblies 800 such thatmultiple lid assemblies 800 nested together occupy less space than the individualun-nested lid assemblies 800 would occupy collectively. This can be particularly useful for packaging, shipping, and presenting the lid assemblies prior to installation on a cup. In some formats, thetab 843 extending from theflap 840 of thecap 807 can affect the stackability of thelid assemblies 800. That is, if thetab 843 extends too far out from the annularupper ridge 820 of the cup, the outerannular sidewall 815 of another stacked lid may inhibit the ability of thelid assemblies 800 to nest with one another, thereby resulting in a nested stack oflid assemblies 800 that occupies more space than necessary. To help improve stackability, the outerannular sidewall 815 of the lid assembly at thedrink opening 822 includes a rounded, or parabolic shaped configuration, as shown in the cross-sectional view of thecover 805 inFIG. 16 . This rounded configuration allows atab 843 of theflap 840 that extends a distance from the outerperipheral edge 823 of theupper ridge 820 to bend downward and tuck between the outerannular sidewalls 815 of two nested lid assemblies without significantly affecting stackability. - Many other modifications may be made to adapt a particular situation or material to the teachings without departing from its scope. Therefore, it is intended that the present method and system not be limited to the particular embodiment disclosed, but that the method and system include all embodiments falling within the scope of the appended claims.
- The present disclosure describes preferred embodiments and examples of lid assemblies.
