Beverage Container with Rotatable Sealing Arrangement

Abstract

A beverage container includes a container body, a lid and a rotatable sealing arrangement. The lid includes a lid body having a top panel and an access opening. The rotatable sealing arrangement includes a cover assembly and a sealing piece. The cover assembly includes a main shaft and a first sealing cover extended from the main shaft and positioned on the top panel of the lid body. The sealing piece is movably coupled to the main shaft, and includes a coupler ring having a through hole and a second sealing cover extended from the coupler ring. When the cover assembly is in an opened position, the cover assembly is rotated so that the first sealing cover is rotated to cover on top of the access opening, while the second sealing cover is driven to move upwardly with respect to the main shaft for blocking the access opening.

What is claimed is: 
     
         1 . A beverage container, comprising:
 a container body having a container cavity; and   a lid, which comprises a lid body detachably attached on said container body to selectively enclose said container cavity, said lid body having a top panel, a through central opening, and an access opening formed on said top panel at a position apart from said through central opening; and   a rotatable sealing arrangement, which comprises:   a cover assembly which comprises a main shaft and a first sealing cover to transversely extended from said main shaft and positioned on said top panel of said lid body; and   a sealing piece movably coupled to said main shaft of said cover assembly, said sealing piece comprising a coupler ring having a through hole formed therein, a second sealing cover sidewardly extended from said coupler ring to position underneath said first sealing cover and said access opening, said cover assembly being rotated on said lid body to operatively move between an opened position and a closed position, wherein in said closed position, said cover assembly is rotated so that said first sealing cover is rotated to cover on top of said access opening, while said second sealing cover of said sealing piece is driven to move upwardly with respect to said main shaft for blocking a bottom side of said access opening so as to prevent liquid from said container cavity to spill out therefrom, wherein in said opened position, said first sealing cover is rotated to expose said access opening to ambient environment, while said second sealing cover is driven to move downwardly with respect to said main shaft so as to allow liquid to flow out of said container cavity through said access opening.   
     
     
         2 . The beverage container, as recited in  claim 1 , wherein said lid body further has at least one securing groove indently formed on a sidewall surrounding said through central opening to form two biasing shoulders with said sidewall at two ends of said corresponding securing groove. 
     
     
         3 . The beverage container, as recited in  claim 2 , wherein said main shaft of said cover assembly has an upper shaft portion, a lower shaft portion, and a middle shaft portion extending between said upper shaft portion and said lower shaft portion, said main shaft further comprising at least one guiding ridge extending along said middle shaft portion along a longitudinal direction thereof in a spiral manner, said guiding ridge having a locking indention formed thereon. 
     
     
         4 . The beverage container, as recited in  claim 3 , wherein said each of said upper shaft portion, said lower shaft portion and said middle shaft portion has a circular cross sectional shape, wherein a diameter of said upper shaft portion of said main shaft is larger than that of said middle shaft portion while a vertical height of said upper shaft portion is smaller than that of said middle shaft portion, said lower shaft portion being divided into a contracted section and a lower end section, wherein a diameter of said contracted section is smaller than that of said lower end section to form a circumferential slot at said lower shaft portion. 
     
     
         5 .
