Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     This invention relates, in general, to a device for packaging and displaying a circular or disc-shaped media and a method for packaging such disc-shaped media and to container lids generally and more particularly, but not by way of limitation to a novel container lid having, a media disc disposed herein and a method of use of the lid.  
         [0003]     Still more particularly, the present invention relates to a new and improved container for initially packaging and thereafter repeated storing of disc-shaped media.  
         [0004]     2. Description of the Related Art  
         [0005]     Media discs disposed in beverage cup lids have become an increasingly popular method of, for example, advertising or offering premiums to buyers of the beverage. Such beverages may, for example, be coffee, soft drinks, or soup. The media disc can be a miniature CD or DVD disc. The patron purchases a drink in the cup and retrieves the media disc from the lid thereof. The media disc can then be played on portable equipment and/or taken to the patron&#39;s home, vehicle or work place for later playing.  
         [0006]     Problems however arise with the closures that have been provided with compartments, particularly when the closures are used for drink cups or other containers containing beverages. Typically, the closure is configured with a opening, such as a pair of crisscrossed slits, for receiving a straw. When a straw is inserted through the slits, liquid can seep through the slits and into the compartment thereby damaging the contents therein, perhaps rendering the contents unusable. Indeed, seepage through the slits is virtually inevitable if the portion of the closure in which the slits is formed is disposed near the level of the beverage. In such a case, downward displacement of the closure as a result of the initial insertion of the straw through the slits typically submerges the slits within the beverage causing substantial seepage through the slits.  
         [0007]     In cases where the closure compartment is at or below the level of the cup lip, the volume of this compartment actually displaces the interior volume of the cup and thus upon attachment of the closure would cause substantial spillage in a fully filled beverage. Moreover, customers at quick service restaurants and the like usually prefer beverages to be filled to the brim. With the beverage filled to the brim, substantial seepage or spillage can occur upon insertion of the straw or attachment of the closure itself causing considerable annoyance to the customer and extra Work for the restaurant staff mopping up the spilled beverages. To avoid this problem, beverage cups are often filled only to a specified level well below the brim of the cup. In restaurants where the cup is automatically filled, automatic filling devices therefore need to be properly set and monitored to ensure that the beverage does not exceed the specified level. If the cup is manually filled by the staff, the staff therefore needs to constantly remember to fill the cup only to the specified level. Furthermore, in many quick service restaurants, the customers fill their own beverage cups, thereby permitting re-fills by the customer. The customers are often not aware that filling the cup to the brim will cause subsequent spillage and, hence, the customers typically overfill the cups resulting in frequent and substantial spillage, in the vicinity of the beverage dispensers.  
         [0008]     In general, a substantial risk of seepage or spillage occurs if either the criss-crossed slits of the closure or the compartment itself are positioned such that, when the closure is mounted to the drink container, the slits or the bottom of the compartment are positioned at or below the top perimeter edge of the drink container. Unfortunately, prior art compartment closures for drink containers are typically configured to position both the criss-crossed slits and the bottom of the compartment well below the top perimeter edge of the drink container. These prior art beverage lids have leakage into the compartment.  
         [0009]     U.S. Pat. No. 6,070.752 to Nava, et al. addressed the leakage problem by raising the straw entry openings, by providing a raised portion within which the criss-crossed slits are formed, the slits are thereby disposed, in use, well above the level of any liquid within the drink container such that, even with a straw inserted through the slits, it is highly unlikely during normal use of the cup that any liquid from within the cup will pass through the slits and into the compartment. Hence contents within the compartment are substantially protected from contamination by the liquid even if the cup is initially filled to the brim and even if significant downward displacement of the closure occurs upon insertion of the straw. This results in a lid that rises high above the beverage.  
         [0010]     It would be desirable to provide a merchandise container closure, particularly a closure for use with drink containers, with a compartment wherein the closure is configured to avoid the aforementioned problems without rising high above the beverage and it is to that end that the invention is primarily directed.  
         [0011]     Known such beverage lids suffer from a number of disadvantages. Many are bulky and can&#39;t be loaded automatically. The ones that are taken off a roll are easily stolen. Sealing with RF or adhesives to prevent leakage is expensive and often unattractive.  
         [0012]     The present invention provides a beverage cup lid and method of use that require no adhesive. RF sealing, or like means of attachment and/or sealing.  
         [0013]     The present invention provides a beverage cup lid with a media disc disposed therein that can have the elements thereof mechanically attached.  
         [0014]     The present invention further provides such a beverage cup lid that can be assembled with high-speed equipment.  
         [0015]     The present invention further provides such a beverage lid with a media disc disposed therein that seals the media disc from the contents of the beverage cup and is attractive.  
         [0016]     The present invention further provides such a beverage lid with a media disc disposed therein that seals the media disc from the contents of the beverage cup and is not held high above the cup and beverage.  
         [0017]     The present invention yet further provides such a beverage cup lid that can be handled without it coming apart.  
         [0018]     Other properties of the present invention, as well as particular features, elements, and advantages thereof, will be elucidated in, or be apparent from, the following description and the accompanying drawing figures.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0025]     Reference should now be made to the drawing. Figures on which similar or identical elements are given consistent identifying numerals throughout the various Figures thereof, and on which parenthetical references to Figure numbers, when used, direct the reader to the view(s) on which the element(s) being described is (are) best seen, although the element(s) may be seen on other Figures also.  
         [0026]      FIGS. 1 and 2  illustrate a container cup lid, generally indicated by the reference numeral  20 , disposed over an open-top container cup  22 . Container cup lid  20  includes a generally planar top  30 , the upper element and a generally planar bottom  32 , the lower element with a generally planar disc-shaped media  34  disposed therebetween. A pair of concentric raised seal rings  40  and  42  are formed on the upper surface of upper element  30 . Seal rings  40  and  42  are hollow, forming spaces  49  and  51  respectively. Seal ring  40  is a major seal and seal ring  42  is a minor seal ring. The terms “major” and “minor” refer to the relative size of the rings, the ring with the larger diameter being the “major” ring. Seal rings may be, without limitation, conical, cylindrical, reverse conical, partially conical and partially cylindrical in shape.  
         [0027]     Container cup lid  20  further includes a generally planar lower element  32 . A pair of concentric raised seal rings  54  and  41  are formed on the upper surface of lower element  32 . Rings  40  and  42  are positioned and dimensioned to sealingly engage rings  54  and  41 , respectively when upper element  30  and lower element  32  are aligned and pressed together forming, an annular chamber to receive and hold a disc-shaped media  34 , which has a central aperture  60  such that it is larger than the outer diameter of seal ring  41  in lower element  32 . The space  52  between concentric seal rings  41  and  54  is sized to retain the disc-shaped media  34 , The space between rings  41  and  54  will vary and is adjusted to the space needed to contain the disc-shaped media  34 . This relationship can be seen with reference to  FIG. 2 . In the alternative, one or more additional seal rings may be incorporated into the cup lid  20  wherein the additional rings are outside the space defined by the minor and major seal rings illustrated in the Figures. The term “ring” as utilized herein is not limited to circular structures. Ring refers to any shape that will permit the incorporation of a disc-shaped media and provide a seal between the upper and lower elements at the central annular aperture and the outer dimension of the disc-shaped media.  
         [0028]     The seals formed by mating rings  40  and  42  with  54  and  41 , respectively are resistant to liquids. When upper element  30  and lower element  32  are sealingly engaged. disc-shaped media  34 , retained therebetween, is protected from contact with the beverage or other material contained in cup  22  when container cup lid  20  is placed thereover.  
         [0029]      FIG. 3  illustrates the elements of container cup lid  20  with media disc  34  disposed therein fitted on top of cup  22 . Upper element  30  has a descending generally cylindrical or generally conical center portion  50 . The lower element  32  is designed to keep the liquid in container cup  22  by sealingly engaging the cup top at the periphery,  72  of lower element  32 .  
         [0030]      FIG. 4  illustrates the configuration of container cup lid  20  with a straw  80  inserted through opening  50  in upper element  30 , the central aperture  60  of the disc-shaped media  34  and the opening  70  in the lower element  32 . The opening  70  in the lower element  32  preferably comprises an X-shaped or similar cuts to facilitate passage of the straw therethrough. Upper element opening  50  preferably has a hole cut into it or, in the alternative, may comprise an X-shaped or similar cuts aligned with similar cuts in opening  70  to facilitate passage of a straw therethrough. It is preferable to use a round opening  50  die-cut in upper element  30  and an X-shaped die-cut opening  70  in lower element  32 .  
         [0031]      FIG. 5  illustrates the central portion of the lower element  32 . Surrounding the minor seal ring  41  are a series of indentations  52  in the planar surface of lower element  32  which are separated by un-indented material of lower element  32 . Two or more indentations may be formed into lower element  32  with four to eight such indentations being preferred.  FIG. 5  illustrates six of said indentations. The result is a spoke-like structure. This spoke-like structure strengthens the plane of element  32 . When lid  20  containing this spoke-like structure is assembled, the resulting lid has been stiffened and resists being deformed and pressed into the beverage container  22  when straw  80  is inserted through the lid. When the disc-shaped media  34  is inserted into lid  20 , the resulting lid structure is further stiffened and provides even greater resistance to being deformed by insertion of a straw  80 .  
         [0032]     Upper element  30  and lower element  32  may be constructed by vacuum-forming or injection molding certain well known plastic materials in a manner well known in the art. The thickness of the plastic sheet material from which blanks are formed may range from about 0.005 inches to, in some extreme cases, to about 0.060 inches. In a particular embodiment, when vacuum formed, 12-mil thick polystyrene or other suitable material is preferred. An important feature of container lid  20  is that the container lid won&#39;t come apart when handled.  
         [0033]     Container cup lid  20  can be assembled using high-speed assembly equipment to combine upper element  30 , lower element  32  and disc shaped media disc.  
         [0034]     In the embodiments of the present invention described above, it will be recognized that individual elements and/or features thereof are not necessarily limited to a particular embodiment but, where applicable, are interchangeable and can be used in any selected embodiment even though such may not be specifically shown.  
         [0035]     Spatially orienting terms such as “above”, “below”, “upper“, “lower“, “innier”, “outer”, “inwardl”, “outwardly”, “vertical”. “horizontal”, and the like when used herein, refer to the positions of the respective elements shown on the accompanying drawings figures and the present invention is not necessarily limited to such positions.  
         [0036]     Although described primarily with respect to digital media disks, it is also to be understood that the closures of the invention may be formed in different configurations to hold and display many different items, such as game cards, game pieces, toys, coupons, stamps and stickers, scratch-off cards and the like.  
         [0037]     It is further to be understood, as part of the invention, that in certain applications of the invention it may be found desirable to permanently join the inner and outer members as by sonic welding or thermal welding, so that the closure must be “broken” in order to gain access to the premium or other item contained between the inner member and the outer member.  
         [0038]     What have been described are various exemplary embodiments of closures for use with drink cups. It should be a understood, however, that the examples described herein merely illustrate aspects of the invention and should not be construed as limiting the scope of the invention which may be implemented in any manner consistent with the general principles of the invention described therein.
