     DETAILED DESCRIPTION 
     The discussion below and the figures referenced herein describe various embodiments of an anti-splash device and methods for preventing unwanted sloshing, splashing and spillage of liquids or other materials placed within container. A number of these embodiments are particularly well suited for implementation in a disposable cup, travel mug and the like. However, it will be appreciated that the features, advantages and other characteristics related to the different embodiments described herein may be incorporated into other types of containers and storage devices, whether intended to retain a beverage or not. 
     An anti-splash device can be positioned within a cup or another container and/or within a lid or other component of a beverage container to eliminate or reduce splashing, sloshing and/or other undesirable movements of the beverage or other materials. In some embodiments, such devices can also help insulate a beverage (hot or cold), while simultaneously permitting normal flow of the beverage into and/or out of the cup or other container. As discussed in greater detail herein, the insulating properties of such devices can be enhanced through a plurality of specially-oriented openings. According to some arrangements, the size and shape of the openings in an anti-splash device can help promote the bonding of fluid across the holes or other openings of the device. This can help create additional thermal barriers against the escape and exchange of fluids (e.g., hot beverages, vapor, warm air, ambient air, etc.) across the anti-splash device. Such anti-splash devices can also be configured to provide structural support to the cup or other container into which the device is placed. In addition, these anti-splash devices can help seal the seam of a paper cup or other container. 
     With reference to  FIG. 1A , an anti-splash device  10  can include a plurality of openings  20 ,  24 . As shown, the anti-splash device  10  can have a generally circular shape. Alternatively, the anti-splash device  10  may have any other shape, such as, for example, polygonal (e.g., triangular, square, rectangular, etc.), oval, elliptical or the like. 
     In addition, the shape of the anti-splash device  10  can be generally planar and/or non-planar shape, such as, for example, convex, concave, domed, spherical, conical, fluted, wavy, curled, grooved, channeled, irregular-shaped and/or the like. 
     In one embodiment, the diameter or other comparable dimension (e.g., length, width, etc.) of the anti-splash device  10  can be approximately 3¼ inches. However, the diameter or other dimension of the anti-splash device  10  can be larger or smaller than 3¼ inches, as desired or required for a particular application or use. Further, as shown in the embodiment of  FIG. 1A , the anti-splash device  10  can have a relatively small thickness as compared to its diameter. For example, the thickness of the anti-splash device  10  can be 0.01 inches, 0.02 inches, 0.04 inches, 0.1 inches, 0.2 inches or thicknesses between such values. In other embodiments, the thickness of the anti-splash device can be smaller than 0.01 or greater than 0.2 inches. 
     The shape, size, orientation, positioning, spacing and/or other features of the openings of the anti-splash device  10  can vary. For example, each of the embodiments of the anti-splash device  10  illustrated in  FIGS. 1A and 1B  includes a row of generally circular openings  20  having a first diameter. In the depicted embodiments, the openings  20  are generally evenly distributed along a circular row located at a particular radius relative to the center of the device (represented by line  22 ). In some arrangements, the anti-splash device  10  comprises eight evenly-spaced 3/16-inch diameter openings  20  which are positioned approximately 0.8 inches from the center of the device  10 . 
     With continued reference to  FIG. 1B , the anti-splash device  10  can include additional openings  24  positioned along a different concentric circular row. In the illustrated embodiment, these additional openings  24  are positioned closer to the periphery of the anti-splash device  10 , along a longer radius from the center of the device  10  (represented by line  26 ). As shown, the additional openings  24  can have a smaller diameter and a different spacing relative to each other. In one embodiment, the anti-splash device  10  comprises sixteen evenly-spaced ⅛-inch diameter openings  24  which are positioned approximately 1.25 inches from the center of the device  10 . However, it will be appreciated that the quantity, diameter, spacing, orientation, shape and/or other characteristics of the openings  20 ,  24  of an anti-splash device  10  can be different than illustrated and discussed herein. 
     As discussed, the anti-splash device  10  can include more or fewer openings than illustrated in the embodiments of  FIGS. 1A through 1C . In addition, the shape, size, spacing, orientation and general configuration of the openings can vary. The design details related to the openings can depend on one or more factors, such as, for example, the type, size, shape, dimensions and other properties of the anti-splash device, the size, shape, dimensions and other properties of the cup or other container into which the anti-splash device may be placed, the type, density, viscosity, temperature range and other properties of the beverage with which the anti-splash device may come into contact, the desired flow rate of fluids (e.g., air, beverage, etc.) through the openings during use, the desired location(s) of the cup that the anti-splash device will contact and/or the like. A device  10  can include openings having more than one shape and/or size. Further, the pattern of openings disposed on a particular anti-splash device  10  may be random instead of regular (e.g., along a particular circle) as illustrated herein. Variations in the shape, size, spacing, randomness and other details regarding the openings are applicable to any embodiments of an anti-splash device discussed herein. 
     With reference to  FIG. 2 , an anti-splash device  10 A can comprise rectangular openings  20 A. In the illustrated embodiment, the openings  20 A are positioned generally radially from the center of the anti-splash device  10 A. As shown, the openings  20 A can be positioned along different rows relative to the center of the device  10 A. As discussed and/or illustrated herein in relation to other embodiments, the shape, size, spacing, location and/or other characteristics of the openings  20 A can vary. 
       FIGS. 3A and 3B  illustrate another embodiment of an opening  20 B for an anti-splash device. As shown, the opening  20 B can be formed by making an X-shaped incision in a surface of the anti-splash device. Such an incision or other cut can create four flap members  21 B. The effective area of the opening  20 B can be adjusted by either lifting or lowering the flap members  21 B relative to the surface of the anti-splash device from which the flap members  21 B were created. In addition, depending on the materials from which they are created, the flap members  21 B can be stiff or flexible. It will be appreciated that an opening  20 B can be created using more or fewer flap members  21 B. Further, the incision or other cut used to form the opening  20 B can have a different shape, size or general configuration than illustrated in  FIGS. 3A and 3B . 
     With reference to  FIGS. 4A and 4B , an opening  20 C can be formed using a generally circular flap member  21 C. The flap member  21 C can be configured to maintain a position away from the surface of the anti-splash device in order to permit fluids (e.g., liquid beverage, air, etc.) to pass therethrough. As discussed, the quantity, shape, size and other properties of the flap member  21 C can vary as desired or required by a particular application or use. The various openings discussed above, or variations thereof, can be positioned on any embodiments of an anti-splash device described and/or illustrated herein. 
     The anti-splash device  10  can be manufactured from one or more flexible, rigid and/or semi-rigid materials. For example, an anti-splash device  10  can comprise polyethylene, high molecular weigh polyethylene, polypropylene, polyethylene terephthalate, polyester, polycarbonate, nylon, polystyrene, epoxy, acrylic, foam material, polymers and other thermoplastic materials, etc. In other embodiments, an anti-splash device  10  comprises other synthetic and/or natural materials, such as for example, paper (including coated and/or impregnated paper or fiber products) or wood-based products (e.g., cardboard), fabric, rubber, metal (e.g., stainless steel), ceramic and/or any other material. Regardless of the exact materials used, the anti-splash devices can be configured to advantageously maintain their physical and structural integrity during at least a single use (e.g., one 8-16 ounce beverage). 
     Thermoplastic anti-splash devices can be manufactured using one or more molding methods, such as, for example, injection molding, blow molding, compression molding, vacuum forming, thermoforming, thermomolding or the like. Alternatively, the devices may be punched, cut, cast, rolled or otherwise manufactured into desired sizes, shapes, thicknesses and configurations. For example, the anti-splash devices can be cut into a desired shape from large sheets of cardboard, plastic or the like. 
     In some embodiments, the anti-splash device can include a coating, film or other layer to further protect the device against aggressive liquids, harmful materials, elevated temperatures or other possibly detrimental environments to which the device may be exposed. For example, an anti-splash device manufactured from cardboard or other paper-based material can include a wax coating to protect against damage resulting from liquid penetration and/or elevated temperatures, degradation due to acidity and/or other potentially harmful effects resulting from contact with a beverage (e.g., coffee, tea, water, etc.). 
     In order to minimize or prevent undesirable sloshing, splashing and/or spilling of a beverage, an anti-splash device can be positioned between the liquid surface of the beverage and the top of the container through which the beverage discharges. The anti-splash device can be secured to or otherwise positioned within a container using one or more methods. As discussed in greater detail herein, in some embodiments, the anti-splash device is sized, shaped and otherwise configured to be snugly positioned at or near the brim of a cup or other container. 
     Regardless of its exact configuration or design, an anti-splash device can help prevent the undesirable movement of liquid contained below it. The device may act as a barrier to reduce or prevent the sloshing or splashing of a beverage. The reduction or prevention of such undesirable liquid movements can help avoid spills, dangerous burns and the like. This can be especially important for cups and other containers that are subject to persistent, strong and/or sudden movements, such as, for example, disposable coffee cups subjected to the movement of a user who is walking or driving, cups or other containers served on airplanes and trains and the like. In addition, such anti-splash devices can help reduce the rate of heat loss out of the container. Further, the anti-splash devices can be configured to form a better seal at the seam of a cup or other container, thereby reducing the likelihood of leaky connections between the cup and the lid or other closure device. Moreover, the anti-splash device can help enhance the structural integrity of the cup, especially at or near the location where the anti-splash device contacts the cup. For example, an anti-splash device which is configured to snugly fit within and contact the interior walls of a cup can help maintain the shape the cup (e.g., generally circular) even when internal or external forces are exerted on the cup (e.g., by grasping or otherwise handling the outside of the cup). 
     The openings of an anti-splash device can advantageously permit liquid to easily flow through the device during dispensing or drinking from the container. For example, when a user wishes to consume a beverage (e.g., coffee, tea, etc.), he or she can simply tilt the cup as he or she would normally do. Coffee or another beverage positioned below the anti-splash device is able to flow through the openings of the device and toward a user. In some embodiments, the rate and pattern of liquid flow through the openings of the anti-splash device can be identical or substantially identical to liquid flow when no anti-splash device is used. However, in other embodiments, the anti-splash device can be configured to slow the flow through the device. To accomplish this, the number, size, shape and/or other properties of the openings can be advantageously modified. 
     In some embodiments, the anti-splash device can be configured to simply float on top of a beverage surface. Thus, it may be desirable for at least a portion of the anti-splash device to have a density which is lower than that of the beverage. For example, the anti-splash device can comprise one or more materials that have a relatively low density, such as polystyrene, foam and/or the like. Alternatively, the anti-splash device can include air pockets, voids and/or one or more other features, materials or components to help it float on the liquid surface. In such arrangements, the anti-splash device can move to generally correspond with the orientation and position of the liquid surface in the cup. Therefore, the vertical position of the anti-splash device relative to a cup&#39;s walls can change as a volume of beverage is added to or removed from a cup. Further, a floatable anti-splash device can be configured to rotate as the cup is tilted or otherwise moved. 
     As discussed, the shape of the anti-splash device can be generally planar and/or non-planar irrespective of whether or not the anti-splash device is free-floating or is secured to one or more portions of the cup. For example, the anti-splash device can be convex, concave, domed, spherical, conical, fluted, wavy, curled, grooved, channeled, irregular-shaped and/or the like. 
     The outer diameter of the anti-splash device can be equal to or smaller than the inner diameter of a cup into which the device may be inserted. Thus, the anti-splash device can fit loosely within the interior of a cup or other container. However, depending on the shape and dimensions of the cup, the anti-splash device may not be capable of lowering beyond a particular cup depth. 
     For example, as illustrated in  FIG. 5 , if a cup  50  includes a draft angle D such that its inner diameter widens toward the top, an anti-splash device  10  can float on the beverage surface as long as the outer diameter of the device  10  does not contact the inner diameter of the cup  50 . In such embodiments, the height of the anti-splash device  10  within the cup or other container can remain generally fixed when the beverage level B drops below a particular height. In other embodiments, the diameter of the device  10  can be greater than the interior diameter of the cup, so long as the device  10  comprises a deformable body whose shape can be resiliently modified. 
     In embodiments where the outer diameter or other outside dimension (e.g., length, width, etc.) of the anti-splash device is consistently smaller than the inner diameter of the cup, the device  10  can be configured to float on or near the beverage surface throughout the entire cup height. The anti-splash device can be sized, shaped and otherwise configured to maintain one or more gaps between the outside of the device and the inside of the cup. However, the size of such gaps can negatively affect the extent to which anti-splash devices minimize or prevent sloshing, splashing, spilling or other movement of the beverage. In addition, such gaps can influence the flowrate at which a beverage is discharged from the cup and/or the device&#39;s ability to thermally insulate a beverage. 
     With reference to  FIG. 6 , an anti-splash device  10  can include an outer sealing portion  30  that is shaped, sized and otherwise configured to engage an internal wall of a cup  50 . As illustrated, the sealing portion  30  can be flexible so that it can deform when a force is applied to it. In some embodiments, the entire perimeter of the anti-splash device  10  comprises such a sealing portion  30 . Alternatively, only one or more perimeter regions of the anti-splash device  10  can include a sealing portion  30 . A sealing portion  30  can be included regardless of the exact shape of the anti-splash device. In addition, any of the embodiments of the anti-splash device described and/or illustrated herein can comprise one or more sealing portions. 
     According to some embodiments, a sealing portion  30  can be an extension of the anti-splash device  10 . For example, the sealing portion  30  can comprise the same or similar materials as one or more other portions of the anti-splash device  10 . In some embodiments, the sealing portion  30  may be thinner and/or may have a different shape than one or more other portions of the anti-splash device  10  in order to provide the sealing member  30  with additional flexibility and/or resiliency. Alternatively, the sealing member  30  can comprise one or more different materials or features than the anti-splash device  10  or a thinner section or piece of the same material. For example, the sealing member  30  can include one or more materials that are softer and/or more flexible than those used on the sealing member  30 , such as, for example, rubber, soft plastic, thin plastic or cardboard or the like. 
     In other embodiments, the sealing portion  30  can be a separate item that is subsequently attached to the anti-splash device  10 . For example, the sealing portion  30  can be attached to the anti-splash device  10  using adhesives, friction fit connections, slip fit connections (e.g., placing an annular sealing member around a disc-shaped anti-splash device) or any other type of attachment device or method. Alternatively, an anti-splash device  10  can be glued, sonic welded, pressure bonded, laser bonded, heat bonded or otherwise attached to the interior of the cup  50 . It should be appreciated that one or more of these attachment methods can be used to connect the anti-splash device  10  to the cup  50  for any of the embodiments disclosed herein. In addition, one or more of these attachment methods can be used to attach the anti-splash device  10  to a lid  500  ( FIGS. 14A and 14B ), an intermediate member  566  ( FIG. 15 ) and any other portion, member or device associated with a cup or other container. In other embodiments, as illustrated in  FIG. 25A , an anti-splash device can include a channel or other resilient feature along its exterior edges that allows a user to snugly position the device within a cup or other container. In such arrangements, the circumferential channel or other feature can be configured to deform (e.g., change its effective diameter or other outer dimension) when urged into a cup against the cup&#39;s interior walls. 
     As illustrated in  FIG. 6 , an anti-splash device  10  can be urged far enough into an interior cavity of a cup  50  so that the sealing portion  30  engages a wall of the cup  50 . Thus, the sealing portion  30  can be used to at least temporarily secure the position of an anti-splash device  10  relative to a cup  50  (e.g., within an interior portion of a cup  50 ). In addition, the sealing portion  30  can help minimize heat exchange between the beverage contained underneath the anti-splash device  10  and the headspace above the anti-splash device  10 . Thus, an anti-splash device  10  with a sealing portion  30  can provide certain insulating advantages. In some embodiments, it may be desirable for the anti-splash device  10  to engage the interior of the cup  50  at or near the upper portion of the cup  50  (e.g., near the cup brim). In other arrangements, as illustrated and discussed with reference to  FIG. 25A , an anti-splash device can include one or more other types of features or members that are configured to engage an interior portion of the cup or other container. In yet other embodiments, an anti-splash device can be adapted to temporarily or permanently engage the interior walls of a cup or some other portion of a container. 
     In some embodiments, the sealing portion  30  can be sufficiently large and flexible to allow a user to position the anti-splash device  10  along various depths of the cup. In such arrangements, the sealing portion  30  can be configured to deform to a greater extent where the inner diameter of the cup  50  narrows. Thus, the vertical position of the anti-splash device  10  can be adjusted according to a user&#39;s preferences. Further, as illustrated and discussed herein with respect to certain embodiments, the anti-splash device  10  can comprise one or more gripping members (e.g., tabs, openings, handles, etc.) to facilitate positioning, re-positioning or removal of device  10 . 
     As illustrated in the embodiments of  FIGS. 7A through 7C , the shape of the outer perimeter of an anti-splash device can vary. In  FIG. 7A , the anti-splash device  10 A comprises a plurality of rectangular-shaped tabs  30 A that generally extend along the outer perimeter. As shown, the tabs  30 A can be equally spaced or substantially equally spaced from one another. However, in other embodiments, the spacing of the tabs  30 A can vary (e.g., can be non-uniform, irregular, etc.). In some embodiments, the tabs  30 A can be configured to engage an inner wall of a cup (not shown) to maintain the position of the anti-splash device  10 A relative to the cup interior. For example, the tabs  30 A can have a particular size, shape, stiffness or flexibility and/or other characteristics to frictionally or otherwise engage a portion of the cup interior. Alternatively, the tabs  30 A can be adapted to maintain the position of the anti-splash device  10 A relative to the cup by at least partially burrowing into the interior wall of a cup. The tabs  30 A or other engagement members can be located along the entire perimeter of the device  10 A. In other embodiments, the tabs  30 A or other engagement members can be intermittently positioned along only one or more portions of the device&#39;s perimeter. 
     With reference to  FIG. 7B , an anti-splash device  10 B can include a plurality of semi-circular tabs  30 B along its outer perimeter. Alternatively, as illustrated in the embodiment of  FIG. 7C , the tabs  30 C along the outer perimeter of an anti-splash device  10 C can form a saw-tooth pattern. It will be appreciated that the outer perimeter of the anti-splash device can have a different shape, size and/or general configuration than illustrated in the embodiments illustrated and/or described herein. Further, the tabs, other engagement members and edge patterns of the devices described herein, or variations thereof, can be used on any embodiments of an anti-splash device. 
     The shape and other details of the perimeter of an anti-splash device can be selected to permit fluid flow between the device and the interior of a cup or other container. Thus, the tabs positioned along an outer portion of an anti-splash device can be shaped, sized and otherwise configured to serve as engagement members to secure the device within a cup and/or as gaps to permit fluid flow across the outer perimeter of the device. 
       FIGS. 8A and 8B  illustrate another embodiment of an anti-splash device  10 D. As shown, the device  10 D can include an upper portion  12  and a lower portion  14 . In the depicted embodiment, the upper portion  12  and lower portion  14  are joined to one another along an outer perimeter  30 D of the device  10 D. As discussed, the outer perimeter  30 D can be configured to engage an interior portion of a cup wall. In other embodiments, the upper portion  12  and the lower portion  14  can be attached to one another along one or more other areas (e.g., along an interior area), either in lieu of or in addition to being attached along the edges. In some embodiments, one or more attachment members or features can be used to connect the upper and lower portion  12 ,  14  to each other. 
     With continued reference to  FIGS. 8A and 8B , the upper portion  12  can comprise a plurality of openings  20 D. As illustrated, the lower portion  14  can also include a plurality of openings  22 D. The shape, size, spacing, degree of overlap and other characteristics of the openings  20 D,  22 D can vary as desired or required by a particular application or use. In  FIG. 8A , the openings  20 D in the upper portion  12  are offset from the openings  22 D in the lower portion  14 . It will be appreciated that the level to which the openings  20 D,  22 D are offset can be different than shown. For example, in some embodiments, the openings  20 D,  22 D are not offset at all, while in other embodiments, there is little or no overlap between the openings  20 D,  22 D. 
     In the embodiment of the anti-splash device  10 D of  FIGS. 8A and 8B , two layers or portions  12 ,  14  are positioned adjacent to each other. However, in other arrangements, the device  10 D can include more or fewer layers or portions. In some embodiments, the adjacently located layers or portions  12 ,  14  can be configured to rotate relative to each other. Thus, the amount of overlap or offset between openings  20 D,  22 D in adjacent portions  12 ,  14  can be selectively adjusted by a manufacturer and/or a user. In such arrangements, the anti-splash device  10 D can comprise a locking member or other feature to maintain the desired overlap between the openings  20 D,  22 D during use. 
     Anti-splash devices having multiple layers or portions can assist in controlling the flow of fluids (e.g., liquid beverage, air, etc.) through the anti-splash device  10 D. In addition, such embodiments can provide thermal insulation benefits by preventing or minimizing the direct exposure of a liquid or other substance to the ambient air located above the device  10 D. 
     For clarity, many of the embodiments of the anti-splash device discussed and/or illustrated herein include a generally planar shape. However, as discussed, it will be appreciated that the anti-splash devices can be modified to include one or more non-planar shapes, such as, for example, convex, concave, domed, spherical, conical, fluted, wavy, curled, grooved, channeled, irregular-shaped and/or the like. 
       FIG. 9A  illustrates another embodiment of an anti-splash device  110 . Similar to other embodiments discussed herein, the depicted anti-splash device  110  can include a main body portion  112  comprising a plurality of openings  120 . The anti-splash device  110  can further include one or more engagement portions  114  along at least a portion of its perimeter. As shown, the engagement portion  114  can include a substantially cylindrical shape and may be generally perpendicular to the adjacent main body portion  112 . Moreover, the main body portion  112  can be attached to the engagement portion  114  at or near the edge of the engagement portion  114 . However, it will be appreciated that the main body portion  112  and/or the engagement portion  114  can have a different shape, size or configuration. For example, the main body portion can have a different shape (e.g., polygonal, oval, non-planar, planar, convex, concave, domed, spherical, conical, fluted, wavy, curled, grooved, channeled, irregular-shaped, etc.), the main body portion  112  can attach to the engagement portion  114  along a different surface or region of the engagement portion  114  or the like. 
     Some or all of the anti-splash devices described and/or illustrated herein, or variations thereof, can comprise one or more flexible, rigid and/or semi-rigid materials, such as thermoplastics, paper based products (e.g., cardboard, etc.) or the like. Further, the anti-splash devices can be disposable or reusable. Likewise, the cups, mugs or other containers into which such anti-splash devices can be placed may vary. For example, the anti-splash devices can be placed within disposable cups (e.g., paper, coated cardboard, plastic, etc.), reusable travel mugs or other container, foodstuff containers and the like. In addition, such cups or containers may be small or large, and may comprise any flexible, rigid or semi-rigid material. 
       FIG. 9B  illustrates one embodiment of an anti-splash device  110  positioned within a cup  50 . The depicted device  110  includes a main body portion  112  and a cylindrical or substantially cylindrical engagement portion  114 , which may be adapted to engage an interior surface of the cup  50 . In some embodiments, the cylindrical or substantially cylindrical engagement portion  114  is configured to generally conform to the shape of the cup wall (e.g., cylindrical, generally cylindrical with a draft angle or other feature, etc.). In use, the anti-splash device  110  may be inserted through the top opening  52  of the cup  50  and urged or otherwise moved downwardly until the engagement portion  114  frictionally contacts at least a portion of the cup&#39;s interior wall. The anti-splash device  110  can be urged downwardly as described above either before or after a beverage has been poured into the cup  50 . In some arrangements, as discussed with reference to the embodiments of  FIGS. 23A and 25A , the engagement portion can be configured to generally conform to the shape of the cup wall. In one embodiment, the further that the anti-splash device is urged downwardly into the interior of the cup or other container, the more that the engagement portion generally takes on the shape of the adjacent wall with which it is in contact. 
     Alternatively, an anti-splash device  110  can be inserted into a cup when the top surface of the beverage is above the depth at which the device  110  frictionally engages an interior surface of the cup  50 . Thus, the anti-splash device  110  can float or substantially float on or near the top surface of the beverage until the beverage level is sufficiently lowered. In embodiments where the device  110  is not configured to float on the beverage surface, the anti-splash device  110  can sink until the engagement portion  114  contacts the cup&#39;s interior wall. Depending on whether the cup and/or the anti-splash device  110  are disposable, the anti-splash device  110  can be recovered from the cup  50  after use. If the anti-splash device  110  is reusable, it may be removed from the cup interior for washing or the like. In order to assist a user in positioning the anti-splash device  110  into and out of a cup  50  or other container, the device  110  can comprise one or more tabs, openings, handles or other gripping members (not shown). 
     In some embodiments, an anti-splash device can be adapted for placement on or near a protrusion member located along an interior of a cup or other container. For example, a cup can comprise one or more flanges, tabs, lips, ridges or the like that extend from its interior wall at one or more desired depths. Thus, as it is lowered into the cup, an anti-splash device can contact such protrusion members and be retained thereon. In other configurations, a cup can include both upper and lower protrusion members extending from its interior surface to maintain an anti-splash device between a desired lower and upper depth. 
     Regardless of how anti-splash devices interface with cups, when a cup is tilted or otherwise moved, the rate at which a beverage flows upwardly across the device can be slower than the rate at which air flows downwardly across the device. As discussed, in some embodiments, the rate of liquid flow through the device can be identical or similar to that when no device is used. Further, the openings and other features of an anti-splash device can be configured to permit a liquid to quickly pass across it when a cup is being filled. 
       FIG. 10  illustrates a main body cutout pattern  18  which is configured to be formed into a disposable cup having an attached anti-splash device  10 . Such a pattern  18  can be manufactured from paper, plastic, other synthetic and/or natural materials and/or the like. The pattern  18  can be cut from a die, punched, molded (e.g., using injection molding, compression molding, thermoforming or other molding techniques) or the like. The depicted cutout pattern  18  can be subsequently rolled and/or otherwise shaped and assembled to form a cup  50 . For example, the free ends of the main cup portion  56  can be glued, sonic welded or otherwise attached to each other to form the substantially cylindrical part of the cup  50 . In addition, a bottom portion (not shown) can be attached to a lower area of the main portion  56  to complete the cup design. Alternatively, the lower part of the main cup portion  56  can be shaped to form the cup bottom. 
     As illustrated, an upper portion  58  of the pattern  18  can be configured to define the upper rim of the assembled cup  50 . With continued reference to  FIG. 10 , the pattern  18  can optionally include a score  59 , step and/or other delineating feature that separates the upper portion  58  from the main generally cylindrical portion  56  of the cup  50 . The upper portion  58  can be sized, shaped and otherwise configured to receive a lid or other attachment member along its rim. 
     With continued reference to  FIG. 10 , an anti-splash device  10  can be attached to the upper portion  58  of the pattern  18 . In the illustrated embodiment, the anti-splash device  10  is attached to the pattern  18  using a single extension tab member  36 . However, one or more other methods can be used to attach an anti-splash device  10  to the pattern  18 , either in lieu of or in addition to using an extension tab member  36 . For example, the anti-splash device  10  can be glued, sonic welded or otherwise connected to the cup  50 . In other embodiments, the pattern can comprise two or more tab members  36  that connect the anti-splash device  10  to a cup  50 . Alternatively, as discussed, the cup  50  can include a protrusion and/or a slot configured to receive an anti-splash device  10 . 
     Once formed from the pattern  18 , the cups  50  can be advantageously placed within each other and packaged for storage and/or transport. The anti-splash devices  10  can remain outside the formed cup  50  during packaging. In such an arrangement, the anti-splash devices can be protected during storage and/or transport. Thus, a user can move the anti-splash device  10  into the cup interior after a beverage has been poured therein. The anti-splash device can remain attached to the upper portion  58  or other location of the cup  50  while the cup  50  is being used. In one embodiment, the score  59  or step in the cup  50  can be used as a ledge or similar resting surface to engage a lower surface of the anti-splash device  10  when the device  10  is lowered into the cup  50 . 
     To ensure that the anti-splash device  10  has been adequately and securely positioned within the cup interior, the device  10  can comprise one or more engagement members along its perimeter, as described herein. For example, the anti-splash device  10  can include one or more protrusions  34  or openings along its perimeter that engage a portion of the cup interior. Such a protrusion  34  can facilitate the handling (e.g., lifting, lowering, repositioning, etc.) of the anti-splash device  10 . 
     With reference to  FIGS. 11A and 11B , an anti-splash device  210  can comprise an upper flange or lip  216  that may be configured to grasp the brim  54  or other upper portion of a cup  50 . The illustrated anti-splash device  210  is similar to the embodiment of  FIGS. 9A and 9B . However, the depicted device  210  additionally comprises a lip  216  extending circumferentially from the engagement member  214 . As with other embodiments described and illustrated herein, the anti-splash device  210  can include a plurality of openings  220  distributed along the substantially horizontal main body portion  214 . In addition, the anti-splash device  210  can have any generally planar and/or non-planar shape, such as, for example, convex, concave, domed, spherical, conical, fluted, wavy, curled, grooved, channeled, irregular-shaped and/or the like. As illustrated in  FIG. 11A , when properly secured to a cup&#39;s brim, the anti-splash device  210  can surround the entire top opening of that cup  50 . The lip  216  of the anti-splash device  210  can be adapted to squeeze, pinch or otherwise securely retain the anti-splash device  210  on the cup  50 . 
     In other embodiments, as illustrated in  FIG. 11C , the anti-splash device  310  is configured to intermittently engage an upper portion of the cup  50  (e.g., only in certain locations). As shown, the anti-splash device  310  can grasp the brim of the cup  50  in four different areas. It will be appreciated that an anti-splash device  310  can include more or fewer lip members  316  than shown in the embodiment of  FIG. 11C . In addition, the shape, size, dimensions, position, spacing, method of securement to the cup  50  and/or other details of the lip members  316  can vary. 
     The anti-splash devices depicted in  FIGS. 11A through 11C , as well as other embodiments discussed and/or illustrated herein, can be further secured to a cup in which they are positioned by covering the cup with a lid. For example, the lid  500  illustrated in  FIGS. 13A through 13C  can be placed on the brim of a cup. Preferably, such a lid  500  can be configured to secure to the upper portion of a cup even when an anti-splash device  210 ,  310  is used. Such lids  500  can comprise a sipping hole  502  and one or more vent holes  503  for convenient access into the interior of a cup. 
     With continued reference to  FIGS. 13B and 13C , a lid  500  can include a resilient circumferential edge  504  that is adapted to receive the brim of a cup within an inner loop region  506 . In one embodiment, the lid  500  can be pressed downwardly against the cup&#39;s top opening until the brim of the cup snaps or is otherwise positioned into the loop region  506  of the lid  500 . The resilient circumferential edge  504  of the lid  500  can help ensure that the rim of the cup remains within the loop region  506 . The snapping feature of the lid&#39;s resilient edge  504  can be configured to engage both the brim and the lip  216  ( FIGS. 11A and 11B ) or lip members  316  ( FIG. 11C ) of an anti-splash device  210 ,  310 . 
       FIGS. 12A through 12C  illustrate one embodiment of an anti-splash device  410  that can be adapted to attach to or fit within a portion of a cup lid. As shown, the anti-splash device  410  can include a cylindrical engagement portion  414  and a main body portion  412  comprising a plurality of openings  420 . In some embodiments, the engagement portion  414  and the main body portion  412  are molded, cut and/or otherwise formed from a unitary member. Alternatively, the engagement portion  414  and the main body portion  412  can be separate items that are subsequently joined using one or more attachment methods. The anti-splash device  410  can be shaped, sized, dimensioned and/or configured differently than depicted in  FIGS. 12A through 12C . For example, device  410  can have a polygonal, oval or other shape. In addition, the main body portion  412  can have any planar and/or non-planar shape as discussed herein. In other embodiments, the engagement portion  414  can be taller or shorter, or may not be continuous around the periphery of the anti-splash device  410 . 
     As illustrated in  FIGS. 12A and 12B , the main body portion  412  of the anti-splash device  410  can include an inner row of openings  420  and an outer row of openings  424 . In one embodiment, the outside diameter of the main body portion  412  is approximately 3 inches, and the height of the engagement portion  414  is approximately 0.4 inches. In addition, the main body portion  412  can comprise eight evenly-spaced 3/16-inch diameter openings  420  along the inner row. In addition, the main body portion  412  can include sixteen evenly-spaced ⅛-inch diameter openings  424  along the outer row, positioned closer to the periphery of the anti-splash device  410 . In some embodiments, the 3/16-inch diameter openings  420  and the ⅛-inch diameter openings  424  can be positioned approximately 0.8 inches and 1.25 inches from the center of the anti-splash device  410 , respectively. 
     It will be appreciated that the shape, size, dimensions (e.g., diameter, thickness, height, etc.) and/or other properties of the anti-splash device  410  can vary. Likewise, the shape, quantity, size, position, spacing and other properties of the openings  420 ,  424  can also be different than illustrated or discussed herein. 
       FIGS. 14A and 14B  illustrate the anti-splash device  410  similar to the one depicted in  FIGS. 12A through 12C  positioned within a lower portion of a cup lid  500 . As discussed, the lid  500  can include a sipping hole  502  and one or more vent holes  503 . In addition, the lid  500  can include a resilient circumferential edge  504  that is adapted to receive the brim of a cup within an inner loop region  506 . As illustrated, the lower opening of the lid  500  can be configured to receive an anti-splash device  410 . In some embodiments, the anti-splash device  410  is sized, shaped and otherwise adapted to snugly fit within a cylindrical portion  505  of the lid  500 . 
     With continued reference to  FIGS. 14A and 14B , the anti-splash device  410  and the lid  500  can be joined by frictionally press-fitting the device  410  within the cylindrical portion  505 . In order to ensure that the anti-splash device  410  can be adequately urged into the lid  500 , the lid can include a tab or other protrusion member against which the engagement portion  414  of the device  410  is configured to stop or engage. In addition to or in lieu of the protrusion member, the lid can comprise a positive engagement member or some other indicia (e.g., a member configured to click or make another sound) that the device  410  has been properly positioned within a lid  500 . In other embodiments, the anti-spill device  410  and the lid  500  can be joined using one or more other methods, such as, for example, using adhesives, clips, screw connections, fasteners or the like. 
     Therefore, such anti-splash devices  410  can be manufactured separately from lids  500  and subsequently connected to them by a manufacturer, user, vendor or some other party. Preferably, the devices  410  can be manufactured in a variety of shapes and sizes to fit different types of commercially available lids. Alternatively, the lid and anti-splash device combination depicted in  FIGS. 14A and 14B  can be manufactured as single unit. Depending on whether the lid  500  and/or the anti-splash device  410  are disposable or re-usable, the device  410  can be configured to be removed from the lid  500  after use. It will appreciated that other embodiments of an anti-splash device as discussed and/or illustrated herein can be configured to removably or permanently attach or join to a lid. 
     The size, shape, configuration and/or other characteristics of the anti-splash devices discussed herein can be selected to facilitate the packaging, transport, storage and/or other activities associated with the handling of such devices. In addition, anti-splash devices can be packaged so as to permit a user to easily and hygienically dispense them. In fact, a user may be allowed to attach an anti-splash device  410  of  FIGS. 12A through 12B , or any other anti-splash device discussed or illustrated herein, without physically handling it, such as by pressing it into the lid while holding the lid. 
       FIG. 15  illustrates one embodiment of an intermediate member  560  comprising an internal anti-splash member  570 . As shown, the intermediate member  560  can be configured to fit on an upper portion  58  of a cup  50 . For example, the intermediate member  560  can include a lower portion  562  adapted to snap onto or otherwise securely engage the rim or other upper portion  58  of the cup  50 . 
     With continued reference to  FIG. 15 , a portion of the intermediate member&#39;s  560  sidewall has been hidden to illustrate the anti-splash device  570  positioned therein. As with other embodiments discussed herein, the anti-splash device  570  can include a plurality of openings  580 . The openings  580  can be configured to allow fluids (e.g., a beverage, other liquids, air, other gases, etc.) to pass across the device  570 . In addition, the openings  580  can help insulate a beverage or other item contained within the cup  50 . Further, the anti-splash device  570  can be formed as a unitary body with the intermediate member  560 . Alternatively, the anti-splash device  560  can be a separate member that is subsequently glued, sonic welded, pressure fitted and/or otherwise attached to the intermediate member  560 . 
     As illustrated in  FIG. 15 , an upper portion  566  of the intermediate member  560  can be sized, shaped and otherwise adapted to receive a lid  500  or other closure member. As with the connection between the intermediate member  560  and the cup  50 , the lid  500  can be configured to snap onto or otherwise securely engage the upper portion  566  of the intermediate member  560 . Thus, the intermediate member  560  can provide the benefits of an anti-splash device without the need to position such a device within the interior of a cup. 
     Intermediate members  560  can be manufactured from paper, plastic, foam or other materials, as discussed herein with respect to the different embodiments of anti-splash devices. Further, intermediate members  560  can be configured to be disposable or reusable. In order to enhance the interface between intermediate members  560  and the adjacent portions of the cup  50  and lid  500 , intermediate members  560  can be shaped and sized according to certain industry standards for cup openings, rim sizes and the like. In addition, it will be appreciated that an intermediate member  560  can have a different size, shape and general configuration than the embodiment illustrated in  FIG. 15 .

In addition, the anti-splash device  570  can be connected to the intermediate member  560  at a higher or lower location. 
     With reference to  FIGS. 16A and 16B , an anti-splash device  610  can also be positioned within a travel mug  70  or other reusable container. As shown, the anti-splash device  610  can have a generally circular shape configured to substantially coincide with the inner wall of the mug  70 . Any of the embodiments of the anti-spill devices discussed and/or illustrated herein can be applied to travel mugs  70  or other types of containers. For example, an anti-spill device  610  can be adapted to float on the surface of the beverage. Alternatively, the anti-spill device may be fixed along a portion of the interior wall of the mug  70 . In other embodiments, the anti-splash device  610  can be attached, either permanently or temporarily, to the lid  74  of the mug  70 . In yet other embodiments, the anti-splash device  610  can include a sealing portion along its periphery to more securely engage an interior wall of the mug  70 . In some embodiments, the anti-spill device includes a resilient edge channel or other feature ( FIGS. 23A ,  25 A) that is configured to engage the interior wall of the container. In such arrangements, at least a portion of the edge of the anti-splash device can be adapted to generally conform and/or take substantially the same shape as the interior wall portion of the travel mug or other container. 
     It will be appreciated that the anti-splash device  610  can have any planar and/or non-planar shape, such as, for example, convex, concave, domed, spherical, conical, fluted, wavy, curled, grooved, channeled, irregular-shaped and/or the like. 
     An anti-splash device can be positioned on one or more rails or other guides disposed on the interior of a cup or mug. These guides can allow a user to select the height or range of height at which the anti-spill device is located. Alternatively, such rails or guides can help ensure that the horizontal position of an anti-spill device does not change, regardless of whether the cup or container contains a beverage. 
     In other embodiments, an anti-splash device can be configured to permit a user to easily change the number and/or size of the openings disposed thereon. For example, the anti-splash device can comprise two complementary members (e.g., planar or non-planar discs or other members) that are capable of rotating relative to one another. As a user rotates the members relative to each other, the number of openings and/or their size can be advantageously varied in accordance with a user&#39;s preference. 
     In some embodiments, a cup can be manufactured together with one or more anti-splash devices. This applies to any of the anti-splash designs discussed and/or illustrated herein. For example, the anti-splash devices can be molded, cut or otherwise formed with the cup or other container. 
     As discussed and illustrated herein, the anti-splash device can have any generally planar and/or non-planar shape or configuration. Some non-limiting example of such shapes and configurations are illustrated in  FIGS. 17A through 17D . For example, in  FIG. 17A , the anti-splash device  710 A includes a generally curved or dome shape. Likewise, in the embodiment depicted in  FIG. 17B , the anti-splash device  710  includes a sharper curvature along its surface. Further, in  FIGS. 17A and 17B , the illustrated anti-splash devices  710 A,  710 B are configured so that their middle portions are generally positioned above the respective edge portions of the devices. As shown, the middle portion in each of these embodiments extends above a horizontal line H drawn through the edges of the anti-splash devices  710 A,  710 B. 
       FIG. 17C  illustrates an alternative embodiment of an anti-splash device  710 C having a curved shape. As shown, a middle portion of the anti-splash device  710 C extends generally below a horizontal line H which joins the edges. Thus, the anti-splash device  710 C of  FIG. 17C  forms a recessed area towards the middle portion of its body. It will be appreciated that the shape, curvature and/or other details of the anti-splash device can be different than in the embodiments illustrated and described herein. For example, with reference to  FIG. 17D , the anti-splash device  710 D can include a rippled or fluted shape. 
     Regardless of their exact shape, size, dimensions and other characteristics, the anti-splash devices preferably include one or more openings  720 A-D,  724 A-D through which a beverage, air and/or other fluid may pass. As described herein, the size, shape, spacing, location and other details of the openings can vary as desired or required by a particular application or use. 
       FIG. 18A  illustrates one embodiment of an opening  720 E through an anti-splash device  710 E. The depicted opening  720 E is shaped and configured so that it begins and ends at different horizontal locations along the body of the device  710 E. As shown, the opening  720 E can be adapted so that there is some horizontal overlap between the upper location  712 E and lower location  713 E of the opening  720 E. Therefore, the opening  720 E can comprise a channel portion  711 E that passes through an interior portion of the anti-splash device  710 E. Such a channel portion  711 E can facilitate in the thermal insulation of the contents situated below the anti-splash device  710 E (e.g., coffee, tea, other hot beverage, etc.). The interior channel portion  711 E can be configured to advantageously make it more difficult for heat to escape through the opening  720 E. In addition, such openings  720 E can help to further enhance the anti-splash features of an anti-splash device  710 E. 
     Alternative embodiments of such openings are illustrated in  FIGS. 18B and 18C . In  FIG. 18B , the channel portion  711 F positioned within the interior of the anti-splash device  710 F is generally longer than the channel portion illustrated in  FIG. 18A . This further distances the upper and lower locations  712 F,  713 F of the opening  720 F, which may further enhance the thermal insulation and/or anti-splash properties of the device  710 F.  FIG. 18C  illustrates an opening  720 G which includes a spiral or corkscrew shape through the depth of the anti-splash device. Therefore, the beverage, air or other fluid passing through the anti-splash device follows a generally tortuous path, as shown in  FIG. 18C . 
     It will be appreciated that the various embodiments of openings illustrated and described herein, such as, for example, those discussed with reference to  FIGS. 18A-18C , can be used in any type of anti-splash device. 
     With reference to  FIGS. 19A and 19B , an anti-splash device  810  can comprise one or more ribs  830 , grooves and/or other members along one or more of its surfaces. In the illustrated embodiment, the ribs  830  are positioned along the bottom surface  816  of the anti-splash device  810 . As shown, the ribs  830  are oriented in a generally radial pattern so that they generally extend toward the outer perimeter of the anti-splash device  810 . In some embodiments, as illustrated in  FIG. 19B , the ribs  830  can join to each other near the center of the anti-splash device  810 . However, in alternative embodiments, the ribs  830  can include a non-radial configuration and may not be connected to each other. For example, in other arrangements, the ribs  830 , grooves or other members can have a different orientation along one or both surfaces of the anti-splash device  810 . For example, the general shape of the ribs  830  or grooves can be circular, concentric, irregular, random and/or the like. The ribs  830  or other support members can help stabilize the anti-splash device  810 . For instance, the ribs  830  or similar members can help prevent the anti-splash device  810  from overturning or otherwise becoming misaligned within the interior of a cup when the device  810  is first positioned and/or during use. 
     With continued reference to  FIG. 19B , the height, width and/or other dimension of the ribs  830  can vary along their length. In  FIG. 19B , the height of the ribs  830  increases toward the radial exterior or the anti-splash device  810 . Further, the depicted ribs  830  include a generally flat bottom surface and rectangular cross-section.

       FIG. 21A  illustrates one embodiment of an anti-splash device  1010 A that is attached to a lid  500  or other closure member of a cup  50 . As shown, the anti-splash device  1010 A includes a connecting member  1016 A which extends from the upper surface of the anti-splash device  1010 A. In the illustrated embodiment, the connecting member  1016 A includes a generally cylindrical shape and is positioned approximately at the center of the anti-splash device  1010 A. However, in other embodiments, the connecting member  1016 A can have any other shape and can be attached to the anti-splash device  1010 A at locations other than the center. In yet other embodiments, an anti-splash device  1010 A includes two or more different connecting members  1016 A for attachment to the lid  500 . 
     With continued reference to  FIG. 21A , the connecting member  1016 A can be manufactured as a unitary member with the anti-splash device  1010 A. For example, the anti-splash device  1010 A can be molded, cast or otherwise formed (e.g., thermoformed) together with one or more connecting members  1016 A. Alternatively, the anti-splash device  1010 A and the connecting members  1016 A can be separate items which are joined using one or more attachment methods or devices, such as, for example, adhesives, sonic welding, fasteners, friction fittings, snap fittings and/or the like. 
     As illustrated in  FIG. 21A , the lid  500  can comprise one or more receiving members  510  which are sized, positioned and/or otherwise configured to receive one or more corresponding connecting members  1016 A of the anti-splash device  1010 A. The lid  500  can be formed with one or more receiving members  510 . Alternatively, the lid  500  and the receiving members  510  can be separate items which can be joined to each other before the lid  500  is used. In some embodiments, the receiving member  510  comprises the female half of a female-male coupling. For example, the receiving member  510  can include a hollow interior cavity portion into which the connecting member  1016 A can be securely inserted. According to some embodiments, the connecting member  1016 A is simply press-fit or friction-fit into the receiving member  510  of the lid  500 . 
     In some embodiments, as depicted in  FIG. 21A , the connecting member  1016 A can include sloped side walls  1018 A to facilitate insertion of the connecting member  1016 A into the receiving member  510  of the lid  500 . 
     It will be appreciated that other types of connections can be used to join a lid  500  to an anti-splash device  1010 A. For example, the connecting member  1016 A can comprise the female half of a fitting which attaches to a male half on the lid  500 . In other embodiments, other types of connections can be used to join the lid  500  and the anti-splash device  1010 A, such as, for example, fasteners, snap-fittings, adhesives, sonic welds and/or the like. In fact, in some embodiments, the lid  500  and the anti-splash device  1010 A can be manufactured as a unitary item. Consequently, the anti-splash device  1010 A and the lid  500  can be removably or permanently attached to each other, as desired or required by a particular application. 
     In embodiments where the anti-splash device  1010 A and the connecting member  1016 A are separate items, one or more additional securement devices or methods can be used to ensure that the anti-splash device  1010 A and the connecting member  1016 A do not unintentionally detach from one another. For example, one or more adhesives, pins, fasteners, sonic welds, tabs and/or other attachment devices or methods can be used. 
     Once the anti-splash device  1010 A has been attached to the lid  500 , the lid  500  can be placed over the brim of the cup  50 . As described herein with respect to other embodiments, the anti-splash device  1010 A can preferably include a plurality of openings  1020 ,  1024  through which one or more fluids may pass. The anti-splash device  1010 A can advantageously reduce the likelihood that liquid contained with the cup  50  undesirably splashes or is otherwise directed toward the user. It will be appreciated that the shape, size, thickness, other dimensions, location relative to the lid  500  and/or the brim of the cup  50 , materials of construction and other properties of the anti-splash device  1010 A can vary. For example, the anti-splash device  1010 A can have a planar, non-planar, domed (e.g., convex, concave, etc.), conical, fluted, grooved or any other shape. 
     The anti-splash device  1010 A, the one or more connecting members  1016 A and the lid  500  can be manufactured from the same or different materials. For example, in one embodiment, the anti-splash device  1010 A, the one or more connecting members  1016 A and the lid  500  are manufactured from polymeric, thermoplastic (e.g., polystyrene), paper-based materials and/or the like. 
     As with all other embodiments discussed and illustrated herein, the position of the anti-splash device  1010 A relative to the lid  500  and/or the brim of the cup  50  can vary. For instance, in some embodiments, it is desirable for the anti-splash device  1010 A to be situated near the brim of the cup  50 . This can facilitate use of the anti-splash device  1010 A even if the internal contents (e.g., beverage, other foodstuff, etc.) of the cup  50  are relatively close to the brim. For example, it may be desirable to position the anti-splash device  1010 A closer to the lid  500  if the cup  50  will contain whip cream, foam or the like. In some embodiments, the vertical location of the anti-splash device  1010 A can be aligned with the brim of the cup  50 . In other embodiments, however, the anti-splash device  1010 A can be positioned above or below the brim of the cup as desired or required by a particular application or use. For example, the anti-splash device  1010 A can be located within the recessed area of the lid  500 . In other arrangements, the anti-splash device  1010 A can be located below the brim of the cup  50 . For non-planar embodiments of the anti-splash device  1010 A, some portions of the anti-splash device  1010 A may be positioned at or above the cup&#39;s brim while other portions may be positioned at or below the cup&#39;s brim. 
     According to some embodiments, the anti-splash device  1010 A, when attached to the lid  500 , is positioned at generally the same vertical orientation as the brim of the cup. In other embodiments, the anti-splash device  1010 A, when attached to the lid  500 , is approximately ⅛-inch below the brim of the cup. However, it will be appreciated that in other arrangements, the anti-splash device  1010 A can be located higher or lower than ⅛-inch below the brim of the cup. 
     In addition, according to some embodiments, the connecting member  1016 A comprises a hollow cylindrical shape having an approximate diameter to ½ to ¾ inches. In other embodiments, however, the connecting member  1016 A can be non-hollow, can have a non-cylindrical shape and/or can have a diameter (or other comparable dimension) which is larger or smaller than ½ to ¾ inches. 
       FIG. 21B  illustrates another embodiment of an anti-splash device  1010 B that is attached to a lid  500  of a cup  50 .

Further, the size, shape, thickness, other dimensions, spacing from the adjacent interior walls of the cup and/or other properties of the anti-splash device  1010 B can vary as desired or required by a particular application or use. For example, in the depicted embodiment, there is a relatively small gap between the outer periphery of the anti-splash device  1010 B and the interior wall of the cup  50 . However, in other arrangements, the outer edge of the anti-splash device  1010 B can contact the adjacent interior wall of the cup  50 . In yet other embodiments, the gap between the anti-splash device  1010 B and the cup interior can be greater than shown in  FIG. 21B . 
     According to some embodiments, the anti-splash device  1010 B, the connecting members  1016 B and/or the lid  500  can be permanently or removably attached to one another. For example, the anti-splash device  1010 B, the connecting members  1016 B and the lid  500  can be securely joined to each other so that they cannot be easily separated during use. However, in other arrangements, one or more of the separate components can be detachable and/or attachable to facilitate disposal, transport, storage and/or other procedures or activities. 
     In the cross-sectional view of the embodiment illustrated in  FIG. 21C , an anti-splash device  1010 C is secured within a recessed area  518 C of a lid  500 C.

As shown, the ribs  1130 , grooves or other members positioned on one or both sides of the anti-splash device  1110  can have a generally radial orientation. However, in other embodiments, the ribs  1130 , grooves or other members can have a different orientation along one or both surfaces of the anti-splash device (e.g., circumferential, other non-radial, random, etc.). For example, the general shape of the ribs  1130  or grooves can be circular, concentric, irregular, random or the like. It will be appreciated that such ribs or grooves can be included on any embodiment of an anti-splash device disclosed and/or illustrated herein. In addition, any of the anti-splash embodiments disclosed herein can include one or more features or characteristics of other embodiments. 
     With continued reference to  FIG. 22A , openings  1120 ,  1124  in the anti-splash device  1110  can be positioned between adjacent ribs  1130 , grooves or other members. In the embodiment illustrated in  FIG. 22B , the openings  1120 ,  1124  are spaced and located according to an orderly pattern. In other embodiments, however, the orientation of the openings can be more or less random. In addition, the quantity, size, spacing, location, shape and other characteristics of the openings  1120 ,  1124  can be different than illustrated herein. 
     In  FIG. 22A , the depicted anti-splash device  1110  comprises a central opening  1126 . In some embodiments, such an opening  1126  can facilitate a user to position the anti-splash device  1110  into or out of a cup. For example, the opening  1126  can be configured so that a user can place his or her finger(s) through it to manipulate the position of the anti-splash device  1110  relative to a cup interior. Such an opening  1126  can have a different location, shape, size and/or other characteristics than the one illustrated in  FIG. 22A . In addition, an anti-splash device  1110  can include two or more such openings  1126  to further facilitate the handling and positioning of the device. In other arrangements, as discussed with reference to the embodiment illustrated in  FIG. 25A , an anti-splash device can comprise one or more handles or other gripping devices that can help a user to selectively manipulate the device into and/or out of a cup or other container. It will be appreciated that such openings and/or handles that assist in the handling of an anti-splash device can be used with any of the embodiments discussed and/or illustrated herein. 
     As shown in  FIGS. 22A and 22B , the anti-splash device  1110  can comprise a deformable peripheral edge  1140 . Such an edge  1140  can help secure the anti-splash device  1110  to the interior of a cup. Moreover, the deformable peripheral edge  1140  can help provide a complete or partial seal between the anti-splash device  1110  and the interior wall of a cup. In the illustrated embodiment, the peripheral edge  1140  is generally continuous around the entire circumference of the anti-splash device  1110 . In other embodiments, however, the edge  1140  can be intermittently positioned around the outer portion of the device  1110 . 
     With continued reference to  FIGS. 22A and 22B , the deformable peripheral edge  1140  can be formed by shaping the outer portion of the anti-splash device  1110  into a folded or accordion-like pattern. Thus, the adjacent folds  1142  of the edge  1140  can stretch or compress as the anti-splash device  1110  encounters frictional resistance from an adjacent surface (e.g., interior wall of a cup). This can help a user securely position the anti-splash device  1110  within the interior of a cup. In addition, in some embodiments, the deformable peripheral edge  1140  can form a partial or complete seal between the anti-splash device  1110  and the interior walls of a beverage container. As discussed and/or illustrated herein with respect to other embodiments, the edge of an anti-splash device can have a different configuration. For example, an anti-splash device may not have a deformable peripheral edge. Instead, the anti-splash device can be configured to not engage the adjacent surface of the cup interior. In other embodiments, as discussed with reference to the embodiments of  FIGS. 23A and 25A , a deformable peripheral edge can have a different shape, size, design and/or configuration. 
       FIG. 23A  illustrates an anti-splash device  1210  which is similar to the embodiment discussed herein in relation to  FIGS. 22A and 22B . As shown, the anti-splash device  1210  includes a plurality of radially-oriented ribs  1230 , grooves or other members positioned along one or both of its surfaces. Further, a plurality of openings  1220 ,  1224  configured to permit a beverage, air and/or other fluids to pass therethrough can be positioned along the surface of the anti-splash device  1210 . The anti-splash device  1210  can also include a center opening  1226 , handle or other feature which facilitates the manipulation of the anti-splash device  1210 , especially when it is being inserted into or removed from the interior of a cup. 
     The anti-splash device  1210  can include a deformable peripheral edge  1240  for securing and/or sealing the anti-splash device  1210  within an interior of a cup. As illustrated in the cross-sectional view of  FIG. 23B , the outer portion of the anti-splash device  1210  can be shaped so as to form one or more channels  1250  or grooves. In  FIGS. 23A and 23B , the channel  1250  is defined by a curled outer end  1248  and an interior ridge  1246 . The channel  1250  can be formed at the time the anti-splash device is being molded, cast, thermoformed or otherwise manufactured. Alternatively, the channel  1250  can be produced by shaping the anti-splash device after the anti-splash device has been produced. In yet other embodiments, the deformable peripheral edge  1240  can be a separate member which is attached to the anti-splash device  1210  using one or more connection methods or devices. The deformable peripheral edge  1240  can be continuous around the entire outer portion of the anti-splash device  1210 . Alternatively, the deformable peripheral edge  1240  can be intermittently located along the outer portion of the anti-splash device  1210 . 
     In use, as the anti-splash device  1210  is being lowered into a cup, the deformable peripheral edge  1240  contacts the interior walls of the cup. If a user continues to move the anti-splash device  1210  deeper into the interior of the cup, the curled outer end  1248  of the deformable peripheral edge  1240  will move towards the interior ridge  1246 , thereby at least partially collapsing the annular channel  1250 . This can help secure the anti-splash device along the interior of the cup and/or form a partial or complete seal between the anti-splash device  1210  and the interior walls of the cup. In some embodiments, this will cause at least a portion of the deformable peripheral edge  1240  to contact an interior wall of the cup or other container, thereby causing such a portion of the peripheral edge  1240  to generally match the shape of the adjacent surface of the cup&#39;s interior wall. Thus, in certain embodiments, if an anti-splash device is pushed far enough into a cup interior, the deformable peripheral edge can form a partial or complete seal with the adjacent portions of the cup&#39;s interior wall. It will be appreciated that such a deformable peripheral edge can be included in any of the embodiments of the anti-splash devices described and/or illustrated herein. 
     As discussed herein, according to some embodiments, the anti-splash device  1210  can be manufactured using thermoforming, casting, vacuum forming, molding and/or any other type of production method. In addition, the anti-splash device  1210  can be manufactured from one or more natural or synthetic materials, such as, for example, polymeric materials, thermoplastics, paper-based materials, films, foams and/or the like. 
       FIG. 24  illustrates one embodiment of an anti-splash device  1310  comprising three finger guides  1350  near its outer portions. As shown, the finger guides  1350  are generally equally-spaced from each other. However, it will be appreciated that in other embodiments, that an anti-splash device can include more or fewer finger guides  1350 , and the location, size, shape, dimensions, spacing and other details regarding the finger guides  1350  can be different than shown and illustrated herein. 
     With continued reference to  FIG. 24 , the finger guides  1350  provide targeted points of contact on which a user may push or exert one or more other forces, stresses, moments and/or the like while positioning an anti-splash device within or onto a cup or other container. In some embodiments, the finger guides  1350  are identical or similar to the adjacent portions of the anti-splash device  1350 . For example, the area comprising a finger guide  1350  can be constructed from the same material, can have the same thickness and/or one or more other characteristics of the adjacent portions of the anti-splash device  1310 . Alternatively, the finger guides  1350  can have a different thickness, shape, materials of construction, surface features or texture and/or other characteristics than the adjacent portions of the anti-splash device  1310 . 
     In some embodiments, the finger guides  1350  can be raised or depressed relative to the adjacent portions of the anti-splash device  1310 . In other embodiments, the finger guides  1350  can have enhanced structural properties relative to one or more other portions of the anti-splash device  1310 . For example, a finger guide  1350  can be thicker, manufactured from stronger or more durable materials and/or the like. In other embodiments, the finger guides  1350  can include reinforcing features, such as, for example, structural members, trusses and/or the like. 
     In some embodiments, the finger guides  1350  can comprise a unique surface texture that facilitates a user in realizing that he or she should exert a force primarily at those locations. In other embodiments, the finger guides  1350  and/or other portions of the anti-splash device  1310  can include text, an image or other indicia that provides instructions, such as, for example, “PUSH HERE” text. Such instruction indicators can be located on or near a surface of an anti-splash device. Alternatively, such instructions can be located on or near a surface of a cup, cup lid and/or the like. 
     According to some embodiments, the finger guides  1350  reduce the undesirable contact of a user with one or more other portions of an anti-splash device  1310 . For example, a beverage seller or buyer can position the anti-splash device  1310  within a desired location of a cup, lid or the like, without unnecessarily touching or contacting portions of the anti-splash device  1310  other than the finger guides  1350 . This can provide an improved hygienic environment. For instance, someone handling the anti-splash device will be encouraged to avoid contact with certain portions of the anti-splash device  1310  when positioning it within a cup, lid and/or the like. In addition, the inclusion of finger guides  1350  can help ensure that the anti-splash device  1310  is positioned correctly within the cup (e.g., right-side-up) and/or that the device  1310  is not damaged during the exertion of pushing, pulling and/or other forces and stresses. 
     It will be appreciated that one or more finger guides or similar devices can be included on any of the embodiments of an anti-splash device discussed herein. 
       FIGS. 25A through 25F  illustrate another embodiment of an anti-splash device  1410  configured for placement within a cup or other beverage container. The depicted anti-splash device  1410  is similar to the embodiment illustrated and described with reference to  FIG. 23A . As shown, the anti-splash device  1410  can have a generally circular shape. According to some embodiments, the outer diameter of the device  1410  is approximately 3.2 inches. However, it will be appreciated that the shape, diameter, other dimensions and/or other characteristics of the anti-splash device  1410  can be different than illustrated and discussed herein. For example, the diameter of the device  1410  can be greater or smaller than 3.2 inches as desired or required by a particular application or use. 
     With continued reference to  FIGS. 25A-25F , the depicted anti-splash device  1410  can include a plurality of openings  1420 ,  1420 , ribs  1420  and/or other members or features along one or more of its surfaces. In addition, the anti-splash device  1410  can advantageously include a handle  1460  or similar grasping member. Such a handle  1460  or grasping member can help a user manipulate (e.g., position, re-position, remove, etc.) the anti-splash device relative to a cup interior. In the illustrated embodiment, the anti-splash device comprises a single handle  1460  located at or near its center. However, in other arrangements, the quantity, location, size, shape and/or other details of the handle  1460  or other grasping member can vary. In some embodiments, an anti-splash device  1410  can include an aperture or other opening (see  FIG. 23A ) that can be used to manipulate the device  1410 , either in lieu of or in addition to a handle or other grasping member. 
     As shown in  FIG. 25A , the handle  1460  can comprise a top ridge  1464  and adjacent side surfaces  1466 . In some embodiments, as illustrated in  FIG. 25A , the side surfaces  1466  can include ridges, texture and/or one or more other features. Such ridges or other features can improve a user&#39;s grasp of the handle  1460  and/or help to further enhance the aesthetics of the device  1410 . As with other embodiments discussed and illustrated herein, the anti-splash device  1410  can be manufactured using one or more methods, such as, for example, molding, casting, thermoforming, other forming methods and/or the like. 
     Further, the anti-splash device  1410  can comprise one or more synthetic and/or natural materials, such as, for example, thermoplastics (e.g., polystyrene), paper products, foam and/or the like. The handle  1464 , ribs  1430 , outer peripheral edge and/or one or more other components of the anti-splash device  1410  can be manufactured as a single member or two or more members that are subsequently joined to each other. In addition, as with other embodiments disclosed herein, the illustrated anti-splash device  1410  can comprise a single layer of plastic or other material throughout its entire surface. Alternatively, in other embodiments, the anti-splash device  1410  comprises two or more layers of plastic or other materials, along all or some of its surfaces. 
     With reference to the cross-sectional views of  FIGS. 25D and 25F , the anti-splash device  1410  can include a deformable peripheral edge  1440  that is sized, shaped and otherwise configured to engage an interior wall portion of a cup or other container. As with other embodiments described and/or illustrated herein, the deformable peripheral edge  1440  can be continuous around the entire circumference of the anti-splash device  1410 . Alternatively, the peripheral edge  1440  can be intermittently located along selected sections of the device&#39;s circumference. 
     With continued reference to  FIGS. 25D and 25F , the deformable peripheral edge  1440  comprises a generally U-shaped or V-shaped channel, which defines an interior space  1444 . As the anti-splash device  1410  is moved into and/or out of a cup, the peripheral edge  1440  can be configured to contact or otherwise engage one or more portions of the cup&#39;s interior walls. For example, the internal diameter of a cup that includes a draft angle generally decreases with increasing depth. Thus, as the anti-splash device  1410  is lowered into a cup, the deformable peripheral edge  1440  may contact the cup&#39;s interior wall. With continued urging deeper into the interior of the cup, the peripheral edge  1440  can begin to deform. For example, the effective diameter of the anti-splash device  1410  may decrease as the circumferential edge of the device  1410  begins to move inwardly. Consequently, in some embodiments, the interior space  1444  defined by the peripheral edge  1440  may shrink relative to its uncompressed, normal state. 
     In some embodiments, the outer peripheral edge  1440  of the anti-splash device  1410  can comprise one or more resilient materials or configurations. This can help create an enhanced seal between the anti-splash device  1410  and the cup or other container, as the resiliency can be configured to force the outer peripheral edge  1440  circumferentially outwardly in the direction of the interior walls of the cup. As illustrated in  FIG. 25F , the outermost portion  1448  of the anti-splash device  1410  can be shaped so as to form an angle  1470  relative to vertical. In some embodiments, this angle can be selected to match or approximate the draft angle of a cup into which the anti-splash device  1410  may be placed. For example, in one embodiment, the angle  1470  is approximately 2 to 20 degrees (e.g., 5, 10, 15 degrees, etc.). However, in other arrangements, the angle  1470  is greater than 20 degrees or less than 2 degrees, as desired or required by a particular application or use. In still other embodiments, the angle  1470  need not match the orientation, size or any other characteristic of a cup&#39;s draft angle. 
     In some arrangements, the outermost portion  1448  of an anti-splash device  1410  does not include a generally flat or uniform surface. For example, the outermost portion  1448  can be ruffled, rippled, textured, fluted, accordion-shaped and/or differently configured. In yet other embodiments, an anti-splash device can include two or more U or V-shaped channels along its peripheral edge. In still other arrangements, one or more other types of deformable features can be included, either in lieu of or in addition to the various embodiments of the peripheral edge described and illustrated herein. For example, an anti-splash device can include a soft, malleable or otherwise deformable resilient material (e.g., rubber, soft plastic, etc.) that does not comprise a channel or other compressible space. 
     In use, the anti-splash device  1410  can be lowered into the interior of a cup by a user. According to some embodiments, a user can grasp the device  1410  using a handle  1460 , an opening  1226  ( FIG. 23A ) and/or any other member or feature. In some embodiments, the anti-splash device is configured to engage the interior walls of the cup at, near and/or just below the brim of the cup. By urging the anti-splash device  1410  deeper into the cup, the user can cause the outer peripheral edge  1440  to compress (e.g., move inwardly) so as to snugly secure the device  1410  within the interior walls of the cup and/or to form an enhanced seal between the device  1410  and the interior walls of the cup. As discussed, this can help prevent undesirable dislodging of the anti-splash device  1410  relative to the cup during use. Further, such a relatively tight fit can help reduce the amount of heat loss that occurs across the anti-splash device. According to some embodiments, urging the anti-splash device  1410  into the interior of a cup increases the contact area between the interior walls of the cup and the outermost portion  1448  of the device  1410 . In some embodiments, the outermost portion  1448  of the anti-splash device  1410  can generally conform to the shape, draft angle and/or other characteristics of the interior of the cup. Consequently, at least a section of the outermost portion  1448  of the anti-splash device  1410  can contact and have substantially the same draft angle as the interior wall of the cup. 
     In addition, a user can remove or reposition (e.g., move upwardly or downwardly, tilt or change the angle relative to horizontal, etc.) the anti-splash device using the handle  1460  or some other feature. Once the anti-splash device  1410  is properly secured within a cup, a lid or other closure member can be optionally attached to the brim of the cup. The anti-splash device can be disposable or reusable, as desired or required by a particular application. For example, the anti-splash devices  1410  can be manufactured as single use items (e.g., thermoformed from polystyrene or one or more other thermoplastic materials). If the anti-splash device comprises more durable and expensive materials (e.g., stainless steel, other metals), the anti-splash device can be removed and reused. 
     With further reference to  FIGS. 25A through 25F , the anti-splash device  1410  can be sized, shaped and otherwise configured to be secured at, near or below the brim of a cup. In embodiments where the anti-splash device  1410  is configured to be situated at or near the brim of a cup, the anti-splash device  1410  can provide certain additional benefits. For example, the anti-splash device  1410  can enhance the structural integrity of the upper portion of the cup, as the cup may be less likely to deform, collapse or otherwise change shape as a result of internal and/or external forces (e.g., grasping force by a user handling the cup, impact force by some object contacting an exterior portion of the cup, etc.). This can help ensure that the beverage or other contents of the cup are not accidentally spilled or compromised. In addition, such a configuration can help ensure that the lid or other closure member remains securely attached to the cup during use. 
     In addition, as discussed, having an anti-splash device  1410  positioned at, near or just below the brim of the cup can help ensure that a beverage does not leak at the interface between the brim of the cup and lid. Certain popular cup designs include a seam (e.g., vertical overlapping seam in a paper disposable coffee cup) or other similar feature that exists as part of the manufacturing process. The anti-splash device  1410  can help seal the seam near the brim of the cup where the cup would otherwise forms a generally poor seal with an adjacent lid or other closure device. Consequently, undesirable leaks can be reduced or prevented. 
     It will be appreciated that the outer peripheral edge  1440  as discussed with reference to the embodiment illustrated in  FIGS. 25A through 25F  can be included in any other embodiment of an anti-splash device described and/or illustrated herein, or a variation thereof. 
       FIGS. 26 and 27  illustrate a cup lid  2400  having a plurality of finger guides  2450  positioned on or near its top surface. As shown, the lid  2400  comprises a total of three finger guides  2450 , spaced approximately 120 degrees from each other. As discussed herein with respect to the anti-splash device illustrated in  FIG. 24 , the quantity, size, spacing, location, shape, dimensions, materials of construction and/or any other characteristics or properties of the finger guides  2450  can vary as desired or required by a particular application or use. 
     With continued reference to the lid illustrated in  FIGS. 26 and 27 , the finger guides  2450  can be positioned near the outer edge of the tops surface of the lid  2400 . However, as discussed, the finger guides  2450  can be positioned in different locations, can have a different size or shape and/or can be configured differently in other embodiments. The finger guides  2450  depicted in  FIGS. 26 and 27  are angled relative to the top surface of the lid  2400 , as well as relative to the side, cylindrical surface of the lid  2400 . In some embodiments, the angle relative to adjacent surfaces can vary between 0 and 90 degrees. In addition, the finger guides  2450  can be textured and/or have one or more other features that help a user determine that the lid should be contacted and/or handled at the finger guides  2450 . 
     The surface of the finger guides  1350 ,  2450  can be planar or non-planar. For example, in some embodiments, the finger guides can be convex or concave, to enhance the feel to a user&#39;s fingers. As discussed, the finger guide surfaces can be textured or smooth. 
     In use, an anti-splash device and/or a lid is contacted, handled and/or pushed relative to a cup using the finger guides. For example, an anti-splash device can be pushed into a lid, into a cup and/or any other location by pushing along its finger guides. Likewise, a cup lid can be snapped onto the brim of a cup by exerting a pushing force on the finger guides. Thus, the finger guides  1350 ,  2450  provide a preferred point of contact for a user of such devices. Consequently, the structural integrity of the device being pushed can be maintained. In addition, the finger guides provide certain hygienic advantages, as the risk of contamination resulting from contact with other portions of such devices can be advantageously reduced or eliminated. 
       FIG. 28  illustrates a cup lid  2400  configured to receive an anti-splash device  2510  within its recessed area. This is similar to the embodiment illustrated in  FIG. 21C . The cup lid  2400  includes one or more finger guides  2450  as discussed above. In some embodiments, the anti-splash device  2510  can include one or more finger guides (not shown), either in lieu of or in addition to the finger guides  2450  of the lid  2400 . Therefore, when the anti-splash device  2510  and the lid  2400  are pushed relative to each other to engage the anti-splash device  2510  within an intended portion of the lid  2400 , a user can advantageously handle the lid  2400  and/or the anti-splash device  2510  at the finger guides. 
     As discussed, any of the embodiments of the anti-splash device described herein and illustrated in  FIGS. 1A through 28  can comprise a planar or non-planar shape. For example, the shape of an anti-splash device can be planar, non-planar, curved (e.g., convex, concave), domed, spherical, conical, fluted, wavy, curled, grooved, channeled, irregular-shaped and/or the like. In addition, such embodiments can comprise features and/or characteristics described and/or illustrated in one or more other embodiments. 
     Further, some of the embodiments of an anti-splash device disclosed herein, such as, for example, those illustrated in  FIGS. 1A-2 ,  5 ,  6 ,  8 A- 9 B,  16 B,  17 A- 20 B,  22 A- 22 F, other embodiments disclosed herein, variations thereof, etc., are configured to be used either as independent members which are not attached to a lid or as members that can be incorporated into or otherwise attached to a lid or other closure device. For example, as discussed and illustrated herein, in embodiments where such anti-splash devices are separate from the lid or other closure member, the anti-splash devices can be configured to be free-floating within a cup interior. In other embodiments, such devices can be configured to secure to, engage, contact and/or otherwise interact with one or more portions of a cup (e.g., interior walls of the cup). Devices that are not configured to contact, attach to or be associated with a lid, other closure member or the like can be stand-alone devices, free-floating devices or members, free standing devices or members, unattached devices or members, independent devices or members, free devices or members, disconnected devices or members, disengaged devices or members, separated devices or members, interior devices or members and/or the like. 
     Alternatively, any of the embodiments of the anti-splash devices described and illustrated herein can be modified or otherwise adapted to be included as part of a lid, other closure member and/or another portion of the cup system. Such devices can be incorporated devices, members or lids, engaged devices, members or lids, dependent devices, members or lids, tandem devices, members or lids, joined devices, members or lids, unitary devices, members or lids, combination devices, members or lids and/or the like. 
     Although this invention has been disclosed in the context of certain preferred embodiments and examples, it will be understood by those skilled in the art that the present invention extends beyond the specifically disclosed embodiments to other alternative embodiments and/or uses of the invention and obvious modifications and equivalents thereof. In addition, while a number of variations of the invention have been shown and described in detail, other modifications, which are within the scope of this invention, will be readily apparent to those of skill in the art based upon this disclosure. It is also contemplated that various combinations or subcombinations of the specific features and aspects of the embodiments may be made and still fall within the scope of the invention.
