A lid for a container body having a container cavity, comprising:
- 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, said main shaft of said cover assembly having 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 transversely extending from said middle shaft portion;
- and
- a rotatable sealing arrangement, which comprises:
- a cover assembly which comprises a main shaft and a first sealing cover 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 from spilling out therefrom, wherein in said opened position, said first sealing cover is rotated to expose said access opening to an 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;
- wherein said coupler ring has a boundary wall surrounding said through hole, said sealing piece further comprising a guiding rim inwardly and peripherally extending from said boundary wall of said coupler ring and slidably engaging with said guiding ridge, said main shaft being arranged to penetrate said through hole of said coupler ring with said guiding ridge slidably engaging with said guiding rim, said guiding rim having a plurality of indentions spacedly formed thereon to divide said guiding rim into a corresponding number of sections between two adjacent indentions, each of said indentions detachably accommodating said guiding ridge so as to provide a temporary locking effect to said main shaft, each of said sections of said guiding rim having an inclined contour so that when said main shaft is rotated, said guiding ridge is arranged to travel along said corresponding guiding rim following a corresponding identical inclined contour so as to move vertically with respect to said lid body.
