Title: Beverage can marketing device with removable center cover

Description:
FIELD OF THE INVENTION 
     The present invention relates to a branding and marketing device that secures to a beverage can top. The device includes a removable central cover or dome that peals away from a rim section. The rim section can remain in place to cover and eliminate the countersink grove found on beverage can tops, while providing continuation branding as the user drinks from the can. The removable central cover can provide under-the-cap like promotions to consumers and can enable a mobile app to scan a code on the underside of the central cover (not visible until the cover is removed) to allow real-time geo-location specific contests, promotions, giveaways and tracking of precisely where the beverage can is opened for consumption. 
     BACKGROUND 
     Conventional beverage cans such as aluminum, tin or steel cans are commonly used to package and contain a variety of carbonated, noncarbonated, and alcoholic and nonalcoholic liquid beverages. Examples of beverages or other consumables that are packaged in beverage cans include carbonated and noncarbonated soda, pop, fruit juice, water, mixers, alcoholic beverages such as beer and wine, and other consumable and even sometimes non-consumable liquids. 
       FIG. 1  provides an illustration of a typical conventional metallic beverage can  100 . A typical beverage can container holds twelve fluid ounces of a liquid such as beer, juice or soda. Conventional can dimensions include heights, diameters and subtle features of the can such as tapering near the top vary and depend often on vendor choice, branding and marketing requirements. Details of the construction of a typical conventional modern beverage can are disclosed in an article/paper entitled “The Aluminum Beverage Can”, written by William F. Hosford and John L. Duncan that was published in the September 1994 issue of Scientific American Magazine, copyright 1994 by Scientific American, Inc. The entire contents of this paper is hereby incorporated by reference in its entirety. This paper shows various example details of conventional beverage can construction. 
     In  FIG. 1 , the typical beverage can  100  includes a can body  105  and a lid or can top  120  (as used herein, the term “can top” refers to a can lid used to cover a beverage can). The body  105  is formed from a piece of continuous metal such as aluminum alloy or steel or other metal that is drawn, ironed, extruded, stretched, pressed, molded, stamped or otherwise shaped into a cylindrical shape to form the body  105 . The above referenced paper provides details on one example process of forming the can body or housing a cold forming and ironing process. Once formed, the can housing or body  105  includes a lower end  108  and an upper end  109 . The lower end  108  typically tapers slightly inwards to form a base or bottom portion  106  of the can that typically tapers inwards at its lowermost end and is smaller in diameter at it base (the portion contacting a surface when the can is upright in position) than a middle area of the body  105 . In many conventional can body designs, the upper end  109  or neck of the body  105  tapers slightly inward at a top of the body  105  and terminates at an upper body edge  110 . The cylindrical-shaped outer surface of the body  105  typically includes decoration that provides a label on the metallic surface of the body that identifies a brand of liquid as well as the contents, ingredients, manufacturer of liquid contained within the can  100  and other information. 
     The can  100  shown in  FIG. 1  is fully assembled, filled with liquid contents and “sealed”. Sealing the can is a process performed during a bottling or canning process when a manufacturer affixes a can top  120  to the upper body edge  110  after placing liquid contents into the can body  105 . In a conventional canning/bottling/seaming process, a canning machine (not shown in this figure) dispenses liquid into the body  105  and thereafter the same or a different machine affixes the can top  120  to the upper body edge  110  by crimping, seaming or pinching a peripheral edge  121  of the can top  120  around the upper body edge  110 , thus forming an airtight and liquid-tight seal between the can top  120  and the body  105 . This seam is sometimes referred to as a double seam and forms the rim at the top of the can. Manufacturers may make and sell can tops  120  and bodies  105  as separate individual items that are then combined as generally explained above during the canning process by a canning/bottling company or beverage/liquid manufacturer to form the can  100  as shown in  FIG. 1 . 
     Prior to canning or bottling, a conventional can top  120  (for example as shown in  FIG. 1  sealed onto the can  100 ) is formed using a can top press, chuck and/or mold(s) that stamp, roll, press or otherwise form a piece of metal such as aluminum alloy or steel into the desired shape of the can top  120 . Once formed, a conventional can top  120  includes a central panel area or upper surface  129  that provides a top or exterior side and that has an underside facing into the can (not shown in  FIG. 1 ) opposite the upper surface  129  of the can top  120  (i.e. the underside of the can top is exposed to the liquid contents contained within the can  100 ). The upper surface  129  of the can top  120  is substantially flat in some conventional can designs, and in other designs the upper surface  129  may have a slight curvature, domed or arced shape with a center region being slightly higher in elevation than an outer peripheral upper surface edge. The conventional can top  120  also includes a tab  115  affixed via a tab connector  116  to the upper surface  129  of the can top  120 . The tab connector  116  may be a rivet or spot weld located at or near a center region of the can top  120 . The tab  115  includes a lifting end  118  and a leveraged end  119 . The leveraged end  119  of the tab  115  is aligned over an openable section  124  defined by a breakaway seam  123  on the can top  120 . The openable section is commonly a circular or oval shaped region defined on the upper can top surface by being pressed, punched, scratched or etched into the upper surface  129  of the can top  120 . This openable section  124  includes a breakaway seam  123  in the upper surface  129  of the can top. The tab  115  and openable section  124  allow a person to open the can  100  to dispense (e.g. drink or pour into a container) the liquid contents of the beverage can  100 . Upon opening, the tab  115  remains affixed to the can top to minimize debris or garbage produced by cans that are sold and opened by consumers. 
     To open the can  100 , a person (not shown) inserts a fingertip, fingernail or other prying device under the lifting end  118  of the tab  115  (between the lifting end  118  and the upper surface  129  of the can top  120 ) and applies an upward or lifting force to the lifting end  118  of the tab  115  up and away from the upper surface  129  of the can top  120 . In response to the raising the lifting end  118  in this manner, the tab  115  pivots at the tab connector  116  and the leveraged end  119  applies a downward force against the openable section  124  causing the openable section  124  to be forced downwards into the can housing  105  relative to the upper surface of the can top  120 . When enough force is applied, the openable section  124  breaks away from the can top  120  along the breakaway seam  123  and bends downwards and inwards into the inside of the can  100 . After opening the can  100  in this manner, the tab  115  remains fixed to the top surface  129  via the rivet  116  and the openable section  124  remains connected to the can top  120  via a small region of the upper surface  129  of the can top that remains connected between the upper surface  129  and the openable section  124  (that is now depressed or bent down into the can body  105 ). That is, the openable section  124  remains attached to the can top  120  since the breakaway seam  123  does not completely surround the openable section  124 . In this manner, the openable section  122  and tab  115  do not break off completely from the can top  120  and avoid becoming loose in the liquid contents of the can  100 . 
     Once the conventional can  100  has been opened by a person in this manner, a person is able to dispense liquid contents from the can  100  by tipping or tilting the can  100  sideways from its upward position toward the openable section  124  (that now provide a hole in the can) in order to pour liquid from the “now open” openable section  124 . The person may dispense the liquid contents of the can  100  into another beverage container such as a glass, cup, bowl or the like, or quite frequently the person may drink directly from the can  100  using his or her mouth. 
     U.S. Pat. No. 6,065,634 discloses some examples of conventional can top designs and also teaches and shows details of machinery to securely seal a can top to a can body using conventional techniques. This patent further shows details of an example seam between a can and can top. The entire teachings and contents of this reference patent are hereby incorporated herein by reference. 
     BRIEF DESCRIPTION 
     Conventional beverage can and beverage can top configurations such as those described above suffer from a variety of deficiencies. In particular, conventional beverage cans and beverage can tops such as the can  100  and can top  120  as shown in  FIG. 1  are subject to contamination issues on their outer surfaces. Surfaces such as the upper surface  129  of the can lid or top  120  and the upper end  109  or neck of the can  100  are highly susceptible to exposure to substances that are containments or debris such as dirt, dust, grime, germs, bacteria, viruses, microbials, fungus, mold, toxins or other depositions. Exterior surfaces of conventional cans and can tops often become “dirty” or unsanitary from exposure to various environmental contaminants shortly after the canning process is complete. Additionally, liquid consumed either directly or indirectly from conventional beverage cans may become contaminated from debris or bacteria on the can tops due to the design of conventional beverage cans and can top or lids. 
     In particular, after the can top and body manufacturing and/or canning process is complete, a conventional can and can top are often exposed to a variety of unsanitary environments. Such unsanitary environments may exist during the conventional processes of can and/or can top manufacturing, filling (canning or bottling)/seaming, packaging and shipping, and while awaiting purchase by the consuming public (e.g., while sitting on supermarket shelves and/or in refrigerators or vending machines), and after purchase but before opening of a conventional can. These contaminants can be swept up in the flow of liquid over a conventional can top when dispensing the liquid from the can. 
       FIG. 2  shows a detailed cross-sectional, profile or cut-away side view of the cross sectional shape of one example design of a conventional can top  120 . Note that in  FIG. 2 , the coupling between the can top  120  and can body or housing  105  are shown only generally and details of the double seam that form the rim  122  of the can are not shown in this figure. During a conventional canning/bottling process, a conventional canning machine (not shown in this figure) forms a rim  122  of the can top  120  by seaming an outside peripheral edge  121  of the can top  120  to the upper end of can body  105  to form a liquid and airtight seal between the can top  120  and the can body  105 . Once the top or lid  120  is seamed to the can housing or body  105  in this manner, the inside surfaces  111  of the can are protected from the outside environment by an airtight seal. To form the seal, the outside edge  121  of the rim may be folded and wrapped around and under the upper body edge  110  to form a double seam that creates the rim  122 . The circular rim  122  continues around the circumference of the can top  120 . The shape or profile (as shown in  FIG. 2 ) of a conventional can top  129  also defines a well area or countersink groove  130  located just inside the rim  122 . Note that depending on the can top  120 , the slope, profile or angle of the inside edge  127  of rim  122  of the can top  120  can be greater or less than that illustrated in this example. Depending upon the manufacturer and process of forming the can top, can housing and seaming process, the exact profile and size of a beverage can housing  105  and top  120  may vary from this figure. 
     The countersink groove  130  defined by a conventional can top  120  is a recessed crevice-like area of open space defined between the inside edge  127  of the rim  122  of the can and an outer edge  135  of the upper surface  129  (i.e. the central panel  129 ) of the can top (the outer edge  135  of this central panel  129  also generally defines the top inside edge of the groove  130 ). The groove  130  dips down in elevation below the upper surface  129  of the can top at the peripheral or outer edge  135  of the upper surface  129  of the can top  120 . If a can  100  is positioned upright, the groove  130  is formed by the surface of the can top between an inside of the rim  122  (on the side of the rim facing the center of the can top) and dips or extends in elevation below the top surface  129  of the can top and ends where the upper surface of the can top begins (at the edge  135 ). The bottom of the groove  130  is typically the lowest point in elevation on the entire can top surface. One purpose of providing this groove is to allow the can top  120  to not distort when the contents of the can are under pressure. Thus the groove  130  provides strength to the can top design and most conventional beverage cans in use today include a groove of this nature. 
     In conventional can and can top designs, the groove is problematic since the groove is a countersink area that is very susceptible to collecting debris such as dirt, dust, sand, or other particulate matter that may settle onto the cap top surface and that may fall into or be pushed or wiped into the groove  130 . As an example, many health conscious consumers who consume liquids from conventional beverage cans  100  have a desire to have the least amount of contamination possible in the liquid dispensed from the can  100 . In an attempt to clean the can top  120  of as much debris as possible, many consumers often wipe the top  120  of a conventional beverage can  100  with a cloth or with their fingers prior to opening the can. This wiping action may result in pushing or forcing debris and contaminants such as dust and dirt into the groove  130  defined by a conventional can top  120  just prior to opening of the can. Additionally, even if not wiped, any loose dirt or contaminants that reside on the top of the can may simply shake loose during handling and fall into the groove prior to opening the can. The groove  130  defined in a conventional can top thus serves as a receptacle or collection area for much of the dirt and debris on a can top. 
     When dispensing (i.e. pouring) liquid contents from a conventional can from the openable section  124 , a person tilts the can so that the liquid contents within the can is able to flow or be poured from the openable section. This tilting action may cause debris that resides in the groove to roll, slide or otherwise move towards a portion of the groove  130  that is adjacent or close to the openable section  124  of the conventional can  100 . As the liquid contents flows out of the conventional can  100 , the liquid flows out of the opening  124  and over a portion of the upper surface  129  of the can top  120 , into and through the groove  130 , and then over and off of the outer edge rim  122  of the conventional can  100 . The turbulent flow of the liquid over this path may cause the liquid to pick up and transport debris from within the groove. Such debris or contaminants can be picked up by the flowing liquid and/or absorbed or dissolved into the liquid and transported for ingestion by the person consuming the liquid either directly or indirectly from the can. In general then, conventional cans and can tops provide for a less sanitary design and the groove  130  provides a receptacle for dirt and debris that is difficult to effectively clean. Further still, the presence of the groove  130  in the path of the liquid can introduce turbulent flow that causes extra release of carbonation within the liquid being poured from a conventional beverage can  100  prior to consumption. Thus the groove  130  in a conventional can and can top design can cause premature release of carbonation that can negatively impact the feeling and taste of the liquid as experienced by a person consuming the liquid. 
     Embodiments disclosed herein provide methods and apparatus to reduce or inhibit the collection of debris on the outer surfaces of beverage cans and can tops, including the rim, groove area, as well as the upper can top surface. Mechanisms and techniques disclosed herein provide embodiments that reduce health risks, cleanliness and sanitary issues posed by designs of conventional beverage cans, can tops and methods of manufacture and use thereof. 
     Generally, embodiments disclosed herein reduce the ability of outer surfaces of a can top and body to collect, trap and/or support growth of debris or other contaminant substances. Embodiments disclosed herein thus provide “clean can” technology that reduces the ability of a can top, rim and upper can housing area to collect debris. 
     Issued U.S. Pat. No. 8,534,490, and issued U.S. Pat. No. 8,708,188 are both invented by the same inventor as the present disclosure. These patents disclose a ring shaped device that secures to a beverage can top (applied either before double seaming the can top to the can housing, or applied after the can top is seamed to the housing). The devices provide a groove cover that essentially covers and removes the surface presence of the groove on the can top. Some embodiments in these patents extend over the rim of the can, while others secure to the can top. The devices can be applied before, during or after the canning operation and are able to remain on the can during shipping, and while opening and drinking from the can. Some versions are able to be removed prior to drinking, and some have portions that can be removed while some portions remain affixed to the can while opening and dispensing the liquid form the can. 
     The groove cover is these two patents can be placed over the groove (e.g. in the canning line while bottling the beverage in the can) and provides an upper groove cover surface that enables easy wiping of the exterior surfaces of the can top. The groove cover of these patents provides an upper surface that slopes up the inside area of the rim and thus provides a nice seamless (e.g. no edges or corners to clean or trap dirt) transition to wipe dirt up and over the rim. Some embodiments of these two patents fill in the groove, while others reside totally above the groove. By filling in or covering or providing an upper surface that resides above the groove and providing a smoother and cleaner can top surface (as opposed to the presence of the groove on a conventional can top), a more health friendly can top results. The devices of these two patents also substantially reduce the metallic taste found in beverages packaged in aluminum beverage cans. This is because the devices of these two patents in many embodiments covers much of the aluminum that contacts a person&#39;s mouth while drinking from the can. The devices of these two patents also promote easier removal of contaminants that resides on the exterior can top surfaces. The devices of these two patents can include an antimicrobial (e.g. within the plastic) to reduce the growth of germs, and the the devices of these two patents can be made of biodegradable materials (e.g. biodegradable plastic) to be an environmentally friend (e.g. eco-friendly or green) product. The devices of these two patents does not limit the recycling process of cans, nor does it interfere with the six pack holder rings (commonly known as Hi-Cones in the Industry). The devices of these two patents device also do not interfere with stacking of the cans. 
     Embodiments disclosed herein include devices that secure to a beverage can top. One example embodiment of such a device includes a rim section having an upper surface that slopes downwards and radially inwards from an upper region of a rim of the can top towards a central panel of the can top. The upper surface of the rim section extends above and across at least a portion of a countersink groove defined by the can top. The rim section includes an inner edge that resides adjacent to the central panel of the can top. A central cover secures to the can top at the inner edge of the rim section. The central cover extends over the top of a central panel of the can top and covers a tab and openable section of the can top. The central cover is removable from the rim section at a releasable boundary defined at the inner edge of the rim section. 
     In another embodiment, the releasable boundary defined at the inner edge of the rim section is a tear away seam defined between the rim section and the central cover. In another embodiment the tear away seam is defined as a thin continuous connection joining the central cover to the inner edge of the rim section. In another embodiment the tear away seam is defined as either a perforated seam joining the central cover to the inner edge of the rim section, or a series of periodic connections that each joining the central cover to the inner edge of the rim section seam, or an adhesive that secures the central cover to the inner edge of the rim section. 
     In other embodiments, the central cover includes visible branding content on a top side of the central cover. In another embodiment the central cover includes visible information on an underside of the central cover. In another embodiment the visible information on the underside of the central cover is a scannable code that is operable to be scanned by a computerized device for transmission along with location information of the computerized device at a time of the scan to a remote computer system. This allows tracking of the geographic physical location of where beverage cans are opened. In another embodiment an upper surface of the rim section includes a visible branding message. In yet another embodiment, the visible information on the underside of the central cover can be a coupon providing a discount, or information to allow a consumer to participate in a contest, promotion, or customer loyalty program, or a code to allow a consumer to obtain digital content, such as a free download. 
     In another embodiment the central cover includes a grasping element that extends from the central cover to allow a user to pull on the central cover to remove the central cover from the can top while leaving the rim section secured to the can top. In another embodiment the grasping element can be a tab (e.g. a pull tab extending from the central panel), a ring, a tape-like material, or a cutaway or small finger opening in the central cover allowing grasping of the central cover for removal from the can top. 
     In another embodiment the rim section and the central cover are separate disconnected pieces of the device, and the central cover is secured to the can top by a physical fit between the inner edge of the rim section and an outer edge of the central cover prior to removal of the central panel from the can top. In another embodiment an outer edge of the central cover has a diameter that is slightly larger at at least one location that an inner diameter of an opening defined by the inner edge of the rim section. When the dome in place on the can top, the outer edge of the central cover resides under the inner edge of the rim section prior to removal of the central cover from the can top. The central cover may be deformable during removal to allow the outer edge of the central cover to pass through an opening defined by the inner edge of the rim section. In another embodiment an outer edge of the central cover snaps onto the inner edge of the rim section to create the releasable boundary that between the rim section and the central cover that unsnaps to allow removal of the central cover from the rim section. In another embodiment, the central cover, after removal from the can top, can be snapped back onto the can top to rejoin the central cover and the rim section. 
     In another embodiment the central cover includes a tab connecting mechanism that temporality secures to a tab on the central panel of the can top when the central panel is placed on the can top. The tab connecting mechanism causes the tab on the can top to lift upwards from the central panel of the can top to open at least a portion of the openable section of the can top upon removal of the central cover from the device. In another embodiment the rim section secures to the can top by snapping onto an outside lower edge of the rim of the can top, the outside lower edge being formed on the can top during couple seaming of the can top to a can housing of the beverage can. In another embodiment the rim section secures to the can top along an upper inner edge of the rim of the can top and does not extend over the rim of the can top. In another embodiment the rim section and central cover are secured to the can top prior to double seaming the can top to a beverage can housing. In another embodiment the rim section and central cover are thermoformed to the can top. Thermoforming can allow the central cover to melt during formation to lay flush on the central panel of the can top and conform to the shape of the tab use to open the can. In yet another embodiment, the rim section and central cover are injection molded directly to the can top (where the can top serves to form part of the mold cavity. In another embodiment, the central cover is dome shaped and defines an area underneath the central cover the covers a tab and openable section of the central panel of the beverage can top. 
     Another embodiment provides a device that secures to a beverage can top. The device comprises a rim section that secures to a rim area of a beverage can as well as a central cover coupled to the rim section along an inside edge of the rim section. The central cover covers an openable section and tab area of the beverage can top. The central cover is removable from the beverage can to allow opening of the openable section of the beverage can while the rim section remains in place on the can top after removal of the central cover. 
     It is to be understood that these are example embodiments only and are not intended to be limiting of the embodiments disclosed herein.

     DETAILED DESCRIPTION 
       FIG. 3  shows a can top device  300  configured in accordance with one example embodiment of the present invention.  FIG. 4  shows a beverage can  200  (e.g. a soda can, beer can or other beverage can) on which the can device  300  from  FIG. 3  is installed. 
     The can top device  300  in  FIGS. 3 and 4  includes a rim section  310  and a removable central cover  312 . The rim section  310  is operable to be secured to the top of a beverage can  200  (as shown in  FIG. 4 ) by snapping onto the rim of the can. The rim section  310  in this example includes an outer surface that begins at the lower edge of an outer skirt  313 . The outer surface of the rim section  310  in this example extends up an outside area of the beverage can, over the rim, and slopes downwards towards the central panel of the beverage can top and over a countersink groove inside the rim of the beverage can top. The rim section  310  ends at an inner edge that joins in this example to an outer lower edge of the removable central cover  312  to form a releasable boundary  314  between the rim section  310  and the central cover  312 . 
     The central cover  312  is a circular dome-like structure in this example. The central cover  312  begins at the inner edge of the rim section  310  (at the releasable boundary  314 ) and includes an upper surface that extends upwards and over the top of the central panel of the beverage can top. In this manner, the central cover  312  extends over and covers the upper surface of the central panel of the beverage can top and covers the tab and openable section of the beverage can to keep these areas clean. By covering the entire can top, the device  300  prevents any debris from contacting the upper surface of the beverage can top, thus resulting in a clean can top. 
     The central cover  312  includes a grasping element  316  which, in this example, is formed as an integral part of the central cover  312 . The grasping element  316  is a small tab or ledge in this example that extends horizontally outward from an upper area of the central cover  312 . The grasping element  316  may extend any distance around the perimeter of the central cover  312 . In the illustrated examples, the grasping element  316  extends approximately ⅛ of the distance around the central cover  3 / 12  thus providing enough from for a consumer to insert one or two fingers under the grasping element  316  in order to remove the central cover  312 . In an alternative embodiment, the grasping element  316  can extend entire circumference of the upper region of the central cover  312  and thus the central cover  312  can be pulled and removed from any direction of position when holding a beverage can. 
     As shown in  FIG. 5 , the grasping element  316 , which is a tab in this example, enables a consumer to use a top of his or her finger(s) placed adjacent to and slightly under the grasping element  316  to pull upwards on the grasping element  316  with force. This upward pulling action on the grasping element  316  causes separation of the central cover  312  from the rim section  310  along the releasable boundary  314 . To enable this separation between the central panel  312  and the inner edge of the rim section  310  to occur, the releasable boundary  314  may be formed, for example, of thin plastic material extending around the lower circular edge of the central cover  312  and the circular inner edge of the rim section  310 . In this manner, the releasable boundary  314  is thin enough that, upon upward force of the grasping element  316 , the releasable boundary  314  is able to break away and tear away enabling removal of the central cover  312 . 
     While the grasping element is shown as a tab in this example, it can be provided in other shapes and configurations. For example, the grasping element may be a tape-like structure that lies flat and is lightly adhered to the sloping surface of the rim section, and may extend as a pullable tab that extends up the sloped upper surface and over the rim. When a consumer purchases the can, he or she can grasp this tab like piece of tape (that can extend over the rim and down a portion of the outside of the rim section (and even down a portion of the side of the can. When doing so, the consumer can pull this tape-like tab to unstick its backside form the outer surface of the rim section. This tape-like tab connects to the base of the central cover and upon pulling this tape-like tab upwards, the releasable boundary  314  begins to breakaway and tear, thus enabling removal of the central cover  312 . The tape-like removing tab can remain affixed to the central cover  312  after removal. In another embodiment, the releasable boundary is provided by an adhesive that extends around the perimeter of the base of the central cover  312 , and when the consumer removes the central panel  312 , they can replace it back onto the can top and the adhesive can re-stick or re-bond the central cover back in place substantially in its original position prior to removal. 
     In another example embodiment, the releasable boundary  314  may be formed as a perforation between the central cover  312  and the rim section  310 . Upon upward force of the grasping element  316 , the perforated releasable boundary  314  tears along the perforation at the inner edge of the rim section thus enabling removal of the central cover  312  from the rim section  310 . In these examples, during removal of the central cover  312 , the rim section  310  remains affixed to the rim of the beverage can upon which the device  300  is secured. 
       FIG. 6  shows the appearance of the beverage can containing the rim section  310  after removal of the central cover  312 . As demonstrated by the above description of a beverage can containing the device  300 , when a consumer purchases a beverage can, the entire can top of the beverage can is covered and free from dirt and debris due to the presence of the device  300 . When the consumer desires to open the beverage can to consume its contents, he or she can remove the central cover  312  as described above to expose the central panel of the can top. The consumer can operate the tab to open the openable section on the can top while the rim section  310  of the device  300  remains affixed to the can. The rim section  310  thus provides continuous branding and marketing to the consumer while consuming the beverage due to the visible information  320  on the rim section  310 . Additionally, since the rim section  310  remains affixed to the can when a consumer opens the can and when the consumer dispenses the liquid from the can, the liquid does not pass into the countersink groove of the can top that exists below the upper surface of the rim section  310 . The smooth sloped upper surface of the rim section  310  produces a less turbulent flow when pouring the liquid from the can. For carbonated beverages the decreased turbulence can reduce the loss of carbonation when pouring from the can and can increase taste when drinking directly from the can. 
     In other embodiments, the rim section  310  can include a flavoring that is picked up by the flow of liquid from the openable section as it passes over the rim section (e.g. during pouring from the can). The flavoring can mix with the liquid to enable a consumer to experience a different taste for the liquid. In still other embodiments, the device  300  can include thermochromic material that can change color based on temperature. This can enable the device  300  to indicate whether or not the can is cold, warm or hot. 
       FIG. 7  shows a slightly different version of the device  600  that does not include the side skirt that extends below the outside of the can. As shown in the example in  FIG. 7 , the releasable boundary  314  extends around the lower perimeter of the removable central cover  312  less than the entire circumference of the lower edge of the central cover  312 . That is, the releasable boundary  314  includes a beginning  314 - 1  and an end  314 - 2 . In this example, the releasable boundary  314  extends between the beginning  314 - 1  and the end  314 - 2 . The region outside of the beginning  314 - 1  and the end  314 - 2  defines a disconnected region  322  at the base of the central cover  312  that is in proximity to (e.g. that is below) the grasping element  316 . That is, in this example the lower outer edge of the central cover  312  that is in proximity to the grasping element  316  does not couple to the inside edge of the rim section  310 . In this embodiment, when a consumer grasps the grasping element  316  in order to remove the central cover  312 , because the outer lower edge of the central cover  312  in proximity to the grasping element  316  does not couple to the region of the inner edge of the rim section  310  that is also in proximity to the grasping element  316 , there is less upwards resistance when pulling upwards on the grasping element  316  since there is no connection between central cover  312  and the inner edge of the ring section  310  in this disconnected region  322 . This enables easier upward lifting and removal and subsequent disconnect of the central cover  312  from the rim section  310 . This also enables the beginning and end of the releasable boundary  314  to begin to tear easier upon upward lifting of the grasping element  16  than if the releasable boundary  314  is fully connected around the entire circumference of the base of the central cover  312 . 
     As a specific example of an embodiment of the device  300  that includes this disconnected region  322 , the perforated edge or thin plastic region that forms the releasable boundary  314  around the lower perimeter of the central cover  312  can extend approximately 300° around the base of the central cover  312 , while the remaining 60° of the circumference of the base of the central cover  312  can remain disconnected from the inside edge of the rim section  310  thus forming the disconnected region  322 . It is to be understood that these degree distances are given by way of example only and that changes to these dimensions are contemplated within the scope of embodiments of the invention. 
       FIGS. 8 and 9  show cross sectional views of example embodiments of the invention as described above and show more particularly the placement of connected regions of the releasable boundary  314  and the disconnected region  322  as described above. 
       FIGS. 8 and 9  also show an example cross sectional profile of the central cover  312 . It is to be understood that this profile, which is dome-like in this example, is not meant to be limiting. In particular, in alternative embodiments the central cover  312  can be shaped in a lower profile manner to define a region to accept the tab that is riveted to the central panel of the beverage can top. In this configuration, when placing the device  300  on the beverage can top, the central cover  312  defines a tab region and needs to be rotationally oriented or aligned with the tab on the can top. The tab region defined in the central cover  312  can receive the tab of the beverage can top in this manner (i.e. when properly aligned) to provide a low profile central cover  213 . 
     In the illustrated configurations described and shown thus far, it is noted that no particular rotational orientation is required when securing the device  300  to a beverage can top. That is, the device can be rotationally oriented with the grasping elementary  16  in any direction relative to the circular shape of the beverage can top and the dome shaped central cover  312  provides enough clearance in any orientation to provide sufficient space for the tab of the beverage can top two reside underneath the central cover  312 . It is also noted that the height of the central cover  312  and existence of the grasping element  316  do not interfere with stacking of the beverage cans equipped with the device  300 . Additionally, in an alternative embodiment of the invention, instead of having a grasping element  316  that protrudes as a small ledge from the top of central cover  312 , the grasping element  16  can be a small recess or indentation within the central cover  312  enabling, for example, a consumer to place his or her fingernail or tip of their finger in the recess or indentation to enable the consumer to pool upwardly on the central cover  312  facilitating its removal. 
     In another alternative configuration, the central cover  312  can include a section on its upper surface and an outer upper peripheral edge that is open (e.g. a small opening or slot). That is, the central cover  312  can define a small opening, slot or hole that has no material present thus enabling a consumer to place his or her fingers into the slot or hole and pull upwardly on the central cover  312  to facilitate its removal. In this example, the grasping element  316  would be the defined opening located on the upper surface of the central cover  312  somewhere along its upper outer peripheral edge. Such an opening the can facilitate insertion of a fingernail or fingertip to remove the central cover  312 . 
       FIG. 10  illustrates an alternative configuration in which the central cover  312  does not get fully removed when a consumer pulls upward on the grasping element  316 . In particular, in this example, the releasable boundary  314  is defined up and across a portion of the central cover  312 /only a portion (e.g., approximately ½ of) central cover is removed when lifting in the grasping elementary  16 . As shown in FIG.  10 , in this configuration central cover  312  includes a removable portion  312 - 2  and a fixed portion  312 - 1  that remains in place after pulling on the grasping elementary  16 . This configuration can be useful and beverage can designs that provide for a push opening in the can top that does not require lifting of a tab rather, requires a user to depress a portion of the central panel of the beverage can top downwards to open the beverage can. 
       FIG. 11  illustrates an alternative configuration of a beverage can top cover device  300  in which the device is composed of two separate parts. In particular, the device  300  includes the central cover  312  which is placed onto the beverage can top in order to cover the openable section and tab of the beverage can top prior to placement of the rim section  310 . The central cover  312  in this configuration can be self-centering within the opening defined by the inner edge of the rim section  310 . The outer lower base of the central cover  312  can have a diameter that is slightly larger than a diameter of the hole defined by the lower inner edge of the ring section  310 . In this manner, when the central cover  312  is placed onto the beverage can top and the rim section  310  is placed over the rim of the can, the central cover  312  self-centers within the hole defined by the rim section  310  and is held in place for the rim section  310  with the rim section snaps onto the beverage can top. This embodiment provides for the ability to manufacture and brand the rim section  310  separately from the central cover  312 . By producing these parts separately and then mating them together during placement onto the beverage can, a beverage manufacture can provide separate branding and marketing messages on each of the central cover  312  and the rim section  310 . For example, the central panel  312  may provide for branding and marketing of a sports team, hotel, airline or other franchise as a tie-in to beverage sales while the rim section  310  provides branding for the beverage brand itself. This enables a beverage manufacture to provide for different central cover  312  that provides branding for different geographic regions or for smaller manufacturing runs of the central cover  312  for a particular event while keeping the rim section  310  consistent with the beverage brand nationwide. These are provided as examples only and it will be apparent to advertising and marketing executives of the many possibilities available for branding and marketing provided by the combination of the rim section  310  and central cover  312 . 
       FIG. 12  illustrates a beverage can top covering device  300  configured in accordance with another embodiment of the invention in which the central cover  312  includes a tab connecting mechanism  340  that is operable to couple to the tab  315  of the central panel of the beverage can top of the beverage can during placement or installation of the device  300  onto the beverage can. In particular, the tab connecting mechanism  340  in this example configuration extends downwards from the underside of the central cover  312  in order to rigidly insert within an opening defined in the tab  315 . Upon insertion of the tab connecting mechanism  340  rigidly into the tab opening of the tab  315 , the tab connecting mechanism  340  secures to the tab  315 . In the illustrated configuration, the tab connecting mechanism  340  includes a base portion that is slightly wider in diameter than the inside diameter of the opening defined in the tab  315 . When the device  300  is oriented with the tab and is pressed onto the beverage can top, the base of the tab connecting mechanism  340  is aligned with the opening defined in the tab  315  and this base portion compresses slightly during pressing of the device  300  onto the can top and the base is forced through the opening defined in the tab  315 . After passing through the opening defined in the tab  315 , the base portion of the tab connecting mechanism  340  expands within the opening and resides just under the tab. This design can benefit from a tab that is optimally designed with an opening to accommodate coupling of the tab connecting mechanism for a secure connection between the central cover  312  and the tab  315 . In this manner, when a consumer pulls upwardly on the grasping element  316 , the tab connecting mechanism  340  concurrently pulls upwardly on the tab  315  in order to begin the process of opening the openable section defined in the beverage can top. In this manner, when a consumer begins removal of the central panel  312 , the consumer simultaneously begins opening of the openable section of the can top. This mechanism may be beneficial to avoid consumers from attempting to remove and steal the central cover  312  prior to purchase of the beverage can in a store because attempted removal of the central cover  312  will result in the breaking of the seal of the openable section of the can top due to the upward lifting of the tab  315  (from its connection to the tab connecting mechanism  340 ). Under the cap like promotions can thus be provided since information on the underside of the central cover is not accessible until the can is at least partially opened. The tab connecting mechanism  340  can be arranged so as to separate from the tab when pulled upward, thus leaving the can slightly opened, while allowing removal of the dome from the tab. 
       FIG. 13  illustrates an alternative embodiment of a tab connecting mechanism  340 . In  FIG. 13 , when the device  300  is installed onto the beverage can top, the tab connecting mechanism  340  includes fingers  345  that extends downwards from the underside of the central cover  312 . These fingers are positioned and aligned in order to receive and surround the end of the tab  315  of the beverage can top that a consumer&#39;s finger would lift in order to open the beverage can. These tab connecting fingers essentially snap onto and around the end of the tab. Subsequently, when a consumer grasps the grasping element  316  in order to remove the central cover  312 , the fingers pull upwards on the end of the tab thus causing partial opening of the beverage can and subsequent separation of the central panel from the tab. 
     In an alternative configuration, to secure a portion of the underside of the central cover  312  to a portion of the tab  315 , a ring of adhesive  350  (e.g., a food grade epoxy) can be placed on the underside of the central cover  312  prior to installation of the device  300  onto a beverage can  200 . This adhesive ring  350  can be sized with a diameter to coincide with aligning of the radially outmost portion of the top of the tab  315  on the top of the beverage can. In this manner, when the device  300  is installed on the beverage can top, a certain section of the adhesive ring will come into contact with the radially outmost portion of the top of the tab  315 . When the adhesive dries to this section of the tab  315 , the underside of the central cover  312  is effectively temporarily secured to the top of the tab  315 . Accordingly, when a consumer pulls on the central cover  312  for removal, the portion that is adhered to the top of the tab  315  pulls upwards on the tab  315  causing the can to partially open. The adhesive can be of a variety that will allow the central cover  312  to be removed from (i.e. broken off of) the tab  315  with sufficient force thus removing the central cover  312  without interfering with consuming the beverage from the can. When the central panel is pulled upwards via the grasping element  316 , the angle of lift of the tab as compared to the central panel are different since the tab pivots on a central rivet on the can top while the central panel peels away and upwards. This divergent angle (between the panel and the tab) that increases as the central panel is lifted more and more upwards can provide the necessary force to cause the connecting mechanism  340  to separate from the tab during the lifting procedure of the central panel, but this separate can occur after the tab has been lifted enough to cause the openable section to be broken on the can top, thus effectively opening the can. The user may be required to further lift the tab after separation and removal of the central panel to fully open the openable section to obtain access to the liquid contents of the can. 
       FIG. 14  illustrates an alternative configuration of a device  300  for covering a beverage can top in which the central panel  312  provides for a releasable boundary  314  that does not fully extend around the entire inside perimeter of the inside edge of the rim section  310 . Instead, a small section of the material in between the central cover  312  in the rim section  310  forms a connected boundary  365  that can remain in place after opening of the central cover  312 . The connected boundary  365  thus allows the central cover  312  to remain secured and affixed to the beverage can even after opening of the central cover  312  to expose the openable section on the can top. As illustrated by dotted lines in  FIG. 14 , the tab and the openable section (that reside under the central cover  213 ) can be oriented orthogonally to the grasping element  316  thus enabling the central cover  312  to open off to the side of the opening in the beverage can top while the central cover  312  hinges on the connected boundary. In this manner, a consumer can open the central cover  312  which hinges on the connected boundary  365 , then open the can using the tab, and the central cover does not become a separate piece of disposable waste, but rather stays with the can. 
     In yet another configuration, the boundary between the central cover  312  and the inside edge of the rim section  310  can include a seal mechanism allowing the central cover  312  can be reached secured in place after removal or opening. That is, in this configuration, the releasable boundary  314  can be a resealable boundary that is releasable for some period of time to enable the consumer to open and drink from or pour the contents of the beverage can out and thereafter the consumer can reseal the central cover  312  back down onto the rim section  310 . This configuration can prevent spillage of the liquid within the can is a consumer does not empty the entire contents. It will be apparent to those skilled in the art that there be me may be many types of resealable seems that can be utilized to reconnect the central cover  312  to the rim section  310 . As an example, a Ziploc type connector seam can be used between the central cover  312  in the rim section  310  that enables the consumer to press the central cover  312  back into place on the rim section  310 . Another example connector would be a magnetic connection between the central cover  312  in the rim section  310  in which the central cover  312  secure itself by having a small metallic ring installed within its base that would be magnetically attracted to a magnetic portion of the rim section  310  located along the inside edge of the rim selection. Another alternative arrangement would be a resealable adhesive will between the central cover  312  in the rim section  310  that enables the central cover to be stuck back down onto the rim section  310  after removal. A food grade re-sticking adhesive can be used for this purpose. 
       FIGS. 15 and 16  illustrate an alternative configuration of a device  300  in accordance with example embodiments of the invention in which a portion of the device includes information on an underside of either the rim section  310  or the central cover  312 . The information can be used to provide contests, giveaways, promotions, coupons, discounts, customer loyalty programs or the like or for other uses as may be seen fit by a beverage company. 
     In this example, the underside of the central cover  312  includes promotion information  450  such as a coupon code or scannable QR code, bar code, game code, or numeric or alpha numeric code or message. A consumer purchases a beverage can containing the device  300  and can either remove the entire device  300  itself or can remove the central cover  312  as explained previously and can thereafter use his or her mobile device&#39;s  410  camera  412  to scan the QR code on the underside of the device  300 . In doing so, the scan application  410  operating within the mobile device can transmit the scanned QR code along with information such as GPS data  417  and time of day, date and/or user identification  418  to a server  460  on a computer network  470  such as the Internet. The server  460  can operate a customer loyalty and tracking application  490  to receive the scanned code  450  and other information ( 417 ,  418 ) and perform a database lookup to determine whether or not the consumer scan the code is an instant winner of a game, contest or promotion. Other information that can be identified with the time and date that the scan to place. The QR code for  50  could include information to identify the particular production date of the beverage and thus beverage companies could identify the amount of time that takes place between the time of production of a beverage and the actual consumption date of the beverage. 
     In this manner, the device  300  provides the ability to for the consumer to remove some or all of the device such as the central cover  312  in order to reveal information enabling a consumer to participate in customer loyalty programs provided by beverage companies or other third-party companies. This allows the device  300  configured in accordance with embodiments of the invention to provide Coke rewards-like functionality as provided by the Coca-Cola Corporation using bottle caps, but for beverage cans. Coke and Coca-Cola are registered Trademarks of Coca-Cola Corporation. By providing a removable central cover  312 , the device  300  can also provide coupons, giveaways or other content on the underside of the central cover  312  thus increasing consumer interest in a given beverage brand that contains the device  300 . When a consumer scans information for  50 , and transmit this information to the server  460 , information such as GPS data  417  can identify exactly where geographically the information was scanned. Since consumers typically remove the central cover  312  and scan the information  450  just prior to opening the beverage can, this would enable beverage companies to identify the specific geographic location where the can was opened and consumed, as well as the time and date and identity of the consumer performing the scan of the central cover  312 . The server computer system can thus track information concerning where beverage cans are opened for consumption. This can be compared with demographic information for these geographic locations to provide valuable insight for beverage marketing purposes. 
     In example embodiments, upper surfaces of both the rim section  310  and central cover  312  can include visible information  320  such as logos (e.g., beverage company logos, sports team logos, or any other logo for a product or service), trademarks, brand names, or other marketing or promotional information. The information  320  can be embossed in or on the device (e.g. raised lettering), embedded in the device or printed on the device, or formed when the device is injection molded (molded in the plastic) or provided for in any other visible manner (e.g. printed on the device  300 ) so that consumers purchasing a beverage can containing the device  300  can see the visible information  320 . The device thus provides an excellent branding and marketing surface over the entire beverage can top, while also keeping the can top clean and free of external debris, dust, germs, bacteria, etc. The device  300  can include an antimicrobial embedded in its material (e.g. antimicrobial contained within the plastic, or sprayed on) to inhibit the growth of germs and bacteria. The device  300  can be made from biodegradable material such as a cellulose plastic that can break down quickly when recycled. The device  300  can be manufactured in large quantities in an inexpensive manner and can be applied in an automated manner quickly in a canning line just after the beverage can top is double seamed to the can housing (e.g. just after filling the can with the beverage or other liquid). 
     It is also to be understood that any of the configurations the device identified and the &#39;490 patent can be equipped with a central cover  312  as explained in the present disclosure. Accordingly, while the present disclosure shows figures containing a device that goes over the rim of the beverage can top, it is to be understood that versions of the device that are adhered to an inside edge of the rim of a can top can also be produced that have a central panel  312  along with the features and functionality described herein. Such a configuration could be glued in or otherwise adhered to the beverage can top and would not extend over the rim of the can. 
     In another configuration, the device itself could be formed on the beverage can top by directly injection molding plastic to the beverage can. In such configurations, the can itself would serve as a portion of the surface for the injection mold. In other words, an injection mold had could be lowered onto the can to produce a rim cover portion  310  the injection molding liquid plastic onto the beverage can itself which hardens to form the rim section  310 . The rim section injection molded directly onto the can top in this manner could include a rich or channel defined along the inside edge of the rim section. This channel could receive the lower edge of the central panel  312  that could snap into the channel. Central panel would thus be placed onto the can after placement of the rim section  310  (either by injection molding or snapping onto the can or otherwise adhering onto the can top). In one configuration, the rim section  310  can also include an inside edge that is operable to receive and secure the lower edge of the central cover  312  within a groove, channel or other fixation mechanism such as snap fitting. The central cover  312  could thus be snap onto the rim section  310  after applying the rim section  310  to the beverage can top. 
     Still further configurations, the central cover  312  and/or the rim section  310  can be manufactured from will a clear or transparent material thus enabling the consumer to see some or a portion of the tab, openable section or other region of the beverage can top through the device  300 . 
     It is to be understood that an important aspect of the certain embodiments disclosed herein is that the when the device  300  is placed onto a beverage can top, the rim section  310  can secure in a fixed manner to the rim of the can (e.g. as disclosed in the &#39;490 patent). In most embodiments, this rim section is not intended to be removed during opening and drinking or dispensing liquid from the can. The central panel  312  is removable as explained above, leaving the rim section  310  behind and in place on the can top. After removal, the rim section  310  provides the inner edge (that defines a central opening) that resides in close proximity to, or lies directly on top of a portion of the central panel of the beverage can top at a location that is in proximity to the openable section of the beverage can top. The inner edge of the rim section thus remains flush against the central panel of the beverage can top after removal of the central cover  312 , thus providing the benefits of the rim section as described in the &#39;490 patent. The central panel combined with the rim section enables the entire can top to be covered and protected from debris, dirt, germs, etc. After removing of the central panel  312 , the consumer may still chose to wipe the upper can top surface, and the upwardly sloped surface of the rim section will assist in easy wiping and removal of any dust or dirt that may have settled onto the sloped surface of the rim section. 
     In an alternative embodiment, the central cover  312  is adhered to the beverage can top via and adhesive and the base of the central cover  312  is shaped to conform to the shape and profile of the sloped surface of the rim section  310 . In this configuration, the base of the central cover  312  can cover a majority of the portion of the sloped surface of the rim section  310  when installed (e.g. via an adhesive). When removing the central cover  312 , the adhesive backing of the underside of the central cover enables the base of the central panel to peel away and expose the sloped surface of the rim section. This configuration enables the central cover  312  to cover not only the central panel of the beverage can top (i.e. the tab and openable sections), but also to cover and protect from debris the sloped upper surface of the rim section that slopes upwards towards the top of the rim of the beverage can.
