Bottle cap

Abstract

The invention discloses a push bottle cap, comprising an outer push cap, an inner ejecting cap, a striker and a waterproof cap. The inner ejecting cap is tightly connected to the upper portion of the waterproof cover, forming a hollow chamber; the top of the inner ejecting cap is tightly attached to the upper inner wall of the outer push cap; the upper portion of the inner ejecting cap is provided with a telescoping device; the waterproof cover comprises a waterproof layer, the outer wall of the waterproof cap and the outer push cap are locked together through a fastener, and the waterproof cap is in screwed connection with a bottle in a threaded manner; the striker is inserted into the upper portion of the inner ejecting cap and located in the hollow chamber, the telescoping device surrounds the striker, and the tip of the striker points to but has no contact with the waterproof layer. The shelf life problem of effervescent tablets or other powders is solved, the whole bottle cap structure may be opened smoothly through the outer push cap, and the different needs of people for drinks and purified water can be met.
