Container cap

Abstract

The present invention relates to a container cap comprising an inner cap and an outer cap. The inner cap has a second cylindrical portion and a joint portion. The second cylindrical portion has an open top, and a lower side end which is to be inserted into a neck, and which has a plurality of outlet ports for discharging additives. The joint portion protrudes from the outer circumference of the top of the second cylindrical portion and is detachably joined to a stopper protrusion of the neck. The outer cap has a first cylindrical portion and a threaded portion. The first cylindrical portion is slidably coupled to the inner surface of the second cylindrical portion from the inner surface of an upper plate in a surface-contacting manner, and the lower end thereof extends axially to close the plurality of outlet ports.; The threaded portion extends axially from the outer surface of the upper plate to be fastened to the outer surface of the neck. When the outer cap is partially opened, said outlet ports are opened to introduce the additives from a receiving space into the main body of a container. When the outer cap is fully opened, the inner cap is separated from the main body of the container together with the outer cap.

Description

technical field [0001] The present invention relates to a container cover, in particular to a container cover as follows. Since the container cover can put additives isolated and stored in the container cover into the container body when the outer cover is partially opened in the first stage, the outer cover can be opened in the second stage. When fully opened, the inner lid is separated from the container together with the outer lid, so it is convenient to use. Background technique [0002] Containers for beverages or cosmetics are generally composed of a container body having a storage space capable of containing contents mixed with various raw materials, and a container cap or cap for airtightly sealing the inlet of the container body. [0003] Recently, with the advent of health drinks or cosmetics, there has been a need for a container having a structure capable of mixing various contents just before use by consumers. [0004] That is, most beverages are mixed in advan...

Problems solved by technology

However, the structure in which the external ratchet is formed on the inner periphery of the outer stopper protrusion located in the narrow annular space increases the difficulty in designing the injection mold and requires a precise mold, which eventually leads to an increase in mold manufacturing cost.

[0015] Also, in the prior art container closures described above, if the user does not fully implement the first stage of opening, the end plates cannot adequately seal the annular space, thereby potentially causing leakage of the mixture inside the container
