Abstract

The invention provides a composite double-layer opening sandwich bottle cap. The composite double-layer opening sandwich bottle cap comprises a lower cap body and an upper cap body which are separable, wherein the upper cap body is provided with a top cap which can be opened and closed; the upper cap body is internally provided with a cavity body capable of containing materials and a structure which can prevent liquid from returning; the structure is positioned at the lower part of the cavity body capable of containing the materials. The composite double-layer opening sandwich bottle cap provided by the invention has the advantages that on the basis of an existing single-layer bottle cap, an inner cavity of the bottle cap is enlarged, so that bags filled with eatable granular materials can be placed in the inner cavity; simultaneously, since two openable parts are arranged, the bottle cap can realize different functions, i.e., pure original liquid can be poured by opening the openable part at the lower part and liquid meeting the drinking needs can be poured by opening the openable part at the upper part, so that the needs of different individuals can be met.

Description

technical field [0001] The invention belongs to the technical field of bottle container packaging, relates to a bottle cap, in particular to a composite double-layer opening sandwich bottle cap.
