Abstract

An easily usable bottle cap includes a cap base, an upper cap, two press buttons, a flexible sucking tube and a straw. The cap base has a lower connect member to engage with an upper end of a bottle containing water or the like. A user only presses the two press buttons inward to compress two coil springs for disengage engage blocks from the upper cap so as to let the upper cap swung up by resilience recovery of the flexible sucking tube. Then a user can use the sucking tube to drink liquid contained in a bottle threadably combined with the cap base through the straw connected with the sucking tube. The upper cap can be kept closed on the cap base by swinging down to engage the engage blocks with hooks of the upper cap.
