Claim:
A water bottle cap for a water bottle having an opening and a water chamber, comprising: a cap body comprising a sealing platform and a surrounding sealing wall extended from said sealing platform for sealedly enclosing around said opening of said water bottle, wherein said sealing wall is adapted to be unsealedly torn off for removing said cap body from said opening of said water bottle; and a water dispensing arrangement, comprising a guiding channel extended from said sealing platform of said cap body and defining a water passage for communicating said water chamber of said water bottle with outside, and a sealing member having a sealing edge sealed at said guiding channel to sealedly close said water passage, wherein said sealing edge of said sealing member defines a breakable edge portion and a retaining edge portion having a thickness thicker than a thickness of said breakable edge portion of said sealing edge of said sealing member; and a plugging guider extended from said sealing member at said retaining edge portion thereof for guiding said spigot adapter to inclinedly slide towards said breakable edge portion of said sealing edge; thereby, when said water bottle is installed on a water dispenser, said spigot adapter of said water dispenser is slid along said plugging guider to break said sealing member at said breakable edge portion thereof so as to plug into said water passage while said retaining edge portion of said sealing member is remained to attach to said guiding channel.
