Title: Resealable container lid assembly

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to lid assemblies for containers. More particularly, it relates to a resealable lid assembly for a beverage container. 
     Description of the Prior Art 
     In prior art beverage container lid assemblies, beverage containers or cans were provided with a “pull tab” which the consumer would grab by a ring, and pull until the tab was removed from the can. Once removed, consumers could discard the tabs anywhere resulting in a litter problem, the tabs themselves being sharp objects capable of causing injury to others, particularly small children. As a result of these problems, tabs that stayed on the can after opening were devised. 
     The present state of the art is to have a “stay on” tab that is attached to the can lid by a rivet formed in the can lid next to the opening. The opening is formed by a score line, or frangible “kiss cut” which breaks when the tab is pulled up by the consumer. The score line, when broken, produces a hinged flap that stays connected to the can lid, but inside the can. 
     While the cans with stay on type tabs are effective at preventing the problems associated with removable tabs, they suffer from the further drawback that the can is not resealable. While bottles with threaded caps can be resealed to maintain the contents fresh for a short time, can with resealable tab assemblies have not caught on. The main drawback with prior attempts at resealable lid assemblies is that the manufacturing process would have to be drastically altered resulting in great cost. Also, no standard has been established that is acceptable to all manufacturers. Typically, the prior art attempts involve several additional components, which components may be made of materials dissimilar from the can itself. 
     Accordingly, a need exists for improved beverage containers that are resealable, cost effective to produce, and require minimum retooling to manufacture. 
     The present invention provides a resealable beverage container lid assembly. The assembly includes a modified tab assembly which includes a sealing portion for releasable engagement within a standard pour opening formed in the top surface of the container. The tab assembly is configured to displace a scored tear panel by way of lever action. A sealing member may be rotated into position to seal the pour opening with the tear panel in the displaced position. 
     SUMMARY OF THE INVENTION 
     It is a major object of the invention to provide an improved resealable beverage container lid assembly. 
     It is another object of the invention to provide an improved resealable beverage container lid assembly having only a single modified component. 
     It is another object of the invention to provide an improved resealable beverage container lid assembly having a stay on tab rotatable between sealed and unsealed positions. 
     These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings. 
     The present invention meets or exceeds all the above objects and goals. Upon further study of the specification and appended claims, further objects and advantages of this invention will become apparent to those skilled in the art.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to  FIG.  1 - 2   , the assembly of the present invention, generally indicated by the numeral  10 , is shown. The assembly  10  is formed in the top portion of a container  100 . The container includes a container cylindrical sidewall  102 , a container closed container closed bottom wall  104 , integrally formed with the container cylindrical sidewall  102  and a resealable container lid portion  110  connected to the container cylindrical sidewall  102  at the end opposite the container closed container closed bottom wall  104 . In the illustrated embodiment, the closed container closed bottom wall  104  and the container cylindrical sidewall  102  are formed from a single piece of aluminum material, using otherwise known processes. The resealable container lid portion  110  is preferably made of the same lightweight aluminum alloy material, and is joined at the upper end of the sidewall through likewise known processes. The resealable container lid  110  portion includes a cap receiving opening  130  which is formed in the lid upper surface  114 . The cap receiving opening  130  is formed near a peripheral edge or lip of the resealable container lid portion  110  as is customary in the art, to allow drinking from the container  100 . A resealable container sealing tab portion or cap  160  fits into the pour opening or cap receiving opening  130  and engages same in a manner described in more detail below. The cap  160  is a part of the tab assembly  162  as will be described in more detail later. The container cylindrical sidewall  102  of the container  100  is preferably tapered at both the upper and lower ends to provide greater structural integrity, particularly for use with pressurized contents, such as when used for carbonated beverages. 
     The resalable container lid  110  has an outer perimeter that is connected to the upper open end of the container cylindrical sidewall  102  of the beverage container, using known processes, to form an enclosure which contains a beverage. Beverages contained therein are not limited, but include carbonated or non-carbonated beverages, and could also include foodstuffs, and non-edible products. The cap receiving opening  130  is integrally formed in the resealable container lid upper surface  114  of the resealable container lid  110  and includes a cap receiving perimeter. A semi-circular score line  136  is formed in the container lid  110  in order to create the opening  130  by way of lever action in the well known manner. In the opened position, the cap receiving opening tear panel  138  remains connected to the lid  110  due to the fact that the circular score line  136  does not make a complete circle or loop; a tear panel hinge  139  is created where the lid  110  is not scored. 
     As seen in figures, the resealable container cap  160  is sized to fit substantially within the cap receiving socket  130 , the cap being an integral part of the tab assembly  162 . The tab assembly  162  is a standard tab assembly coated with a rubberized sealing material  164 . The material, which may be a rubberized material such as neoprene, is sufficiently flexible to provide sealing engagement within opening  130  by compression fit. The otherwise standard tab assembly functions to create the opening  130  by way of lever action in the well known manner. A rivet  170  positioned in the lid  110  allows for rotating the entire assembly as seen in  FIGS.  1 B- 1 D . The cap  160  has a tapered underside  172  and may optionally include an annular groove to allow for compression fit. 
     In use, the tab assembly  162  is used to form opening  130  in the conventional manner. If desired, the user may then rotate the assembly as shown in  FIGS.  1 C and  1 D  to the sealing position as shown in  FIG.  1 D . 
     From the foregoing description, one skilled in the art can easily ascertain the essential characteristics of this invention and, without departing from the spirit and scope thereof, can make various changes and modifications of the invention to adapt it to various usages and conditions. 
     It is to be understood that the present invention is not limited to the sole embodiment described above, but encompasses any and all embodiments within the scope of the following claims:
