Abstract: This disclosure relates to a cover and a water or liquid container using the cover. An example cover includes a base; an opening in the base; a lid hinged to the base, the lid including a retention feature; a pressing ring hinged to the base, the pressing ring releasably couplable with the retention feature and a button pivotally coupled to the base, the button releasably couplable with the retention feature, wherein rotation of the pressing ring releases the pressing ring from the retention feature, causes rotation of the button, and releases the button from the retention feature, wherein release of the pressing ring and the button from the retention feature enables the lid to move from a first position in which the lid covers the opening to a second position in which the opening is exposed.

Abstract: This disclosure relates to a cover and a water container using the cover. The cover comprises a cover base, an upper cover, a bracket, a pressing ring and a button. The upper cover is hinged to the cover base and has a first snap portion. The pressing ring is hinged to the bracket and has a snap-fit portion for snapping the upper cover. The button is pivotally arranged on the cover base in a lever manner and has an upper end and a lower end. The upper end of the button has a second snap portion. The pressing ring is connected to the cover base by a reset elastic member. When the pressing ring is turned relative to the bracket and pushes against the lower end of the button, a pushing force is applied to the lower end of the button to disengage the second snap portion from the first snap portion. The user operates the overturn of the pressing ring with one hand to disengage the pressing ring from the upper cover and disengage the button from the upper cover, and then the cover is completely opened.
