Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-liquid mixing / dispensing container. 2. Description of the Related Art If two kinds of different liquids are stored in a mixed state, they may react with each other and lose their effectiveness. Various containers are known, for example, Japanese Utility Model Application Laid-Open No. 61-147133.
The container described in the above publication raises the mouth and neck from the upper end of the trunk, and a lower container body in which the inner plug is fitted to the inner surface of the mouth and neck, and the lower peripheral wall is screwed to the upper outer surface of the mouth and neck. And an upper container body having a lower push-down rod hanging down from the lower surface of the upper small-diameter tape-shaped pouring cylinder rising from the upper end of the peripheral wall. The lower end of the lower rod pushes down the inner plug to drop it into the lower container so that the liquid in the upper and lower containers can be mixed. [0003] However, the above-mentioned conventional container is formed so that different kinds of liquids are mixed by removing the inner stopper separating the upper container from the lower container from the mouth and neck, so that the different kinds of liquid in the upper and lower containers are once mixed. In some cases, the mixed liquid may be obtained more than necessary, and the mixed liquid is not suitable for long-term storage.
It was uneconomical because it tended to be discarded without being used. According to the present invention, a cylindrical portion vertically extending from both the left and right portions of the lower surface of a horizontal plate is fitted to the outer surface of each of the mouth and neck portions of the left and right small containers containing different liquids. Form a flow channel for allowing different liquids to flow out to the left and right inside the pouring cap attached to the cap, and form a single pouring cylinder above the pouring cap that serves as a common outlet for both the left and right flow channels By doing so, it is formed so that different kinds of liquids can be mixed and poured out from the dispensing cylinder, and provided so that a required amount of the mixed liquid can be obtained. By forming so that the amount of dissimilar liquid is poured out,
