Double-layered bottle cap

Abstract

A double-layered bottle cap comprises an inner cap and an outer cap, wherein a helical guide sliding chute is arranged in the inner cap, a bulge corresponding to the guide sliding chute is arranged on the outer cap, and the guide sliding chute is provided with a stop end used for clamping the bulge; a thin sheet is arranged between the inner cap and the outer cap, and a sharp point used for stabbing the thin sheet is arranged inside the outer cap; and granules can be placed in the space between aluminum foil and the outer cap, when the bottle cap is required to be used, the outer cap is selected first for accommodation, due to the restriction function of the bulge, the sharp point glides down and stabs the aluminum foil, and when the bulge is clamped at the stop end, the aluminum foil is gashed by the sharp point, so that the granules slide into the bottle. According to the design of the double-layered bottle cap, the granules are prevented from being contacted with water, so that the guarantee period of beverages such as tea, panax notoginseng beverage, Chinese wolfberry and the like is prolonged, the beverage can be drunk once made, and convenience and fastness are provided. The double-layered bottle cap is unique in design, extra actions are not required, and the rotational direction is not needed to change, namely, the original decapping habit is not needed to change.

Description

technical field [0001] The present invention relates to a bottle cap, more particularly, to a double-layer bottle cap. Background technique [0002] Bottle caps are used to seal bottles.
