DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-liquid mixing / dispensing container.

[0002]

[Prior art]

When two kinds of different liquids are stored in a mixed state, they cause inconveniences such as reacting with each other and losing their efficacy. Therefore, various containers are known which are used by mixing at the time of use. For example, see 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 with a 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 an 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.

[0004] As a container capable of solving the above-mentioned drawback, there is, for example, a container described in Japanese Utility Model Laid-Open No. 4-50682. A mounting member which is vertically attached from both left and right portions of the horizontal tube portion is fitted to each other, and a pouring member which stands up the pouring tube portion from the middle in the left and right direction of the horizontal tube portion is provided, and the pouring member is pressed down. It is formed so that the mixed liquid is discharged from the discharge cylinder portion when both stems are lowered.

[0005] However, in the conventional example, since different kinds of liquids are mixed inside the horizontal cylinder, if the ejection is stopped,
If the mixed liquid in the horizontal cylinder portion and the discharge cylinder portion remains without being poured out and the residual liquid is left for a long period of time, the mixed liquid having lost the effect will be poured out first in the next use. In recent years, the problem has been that Freon gas used in aerosol containers destroys the ozone layer, and a container that can obtain the required amount of mixed liquid without using an aerosol container is required. Have been.

FIG. 1, FIG. 2, and FIG. 3 show a first aspect of the present invention in which a spout cap with a nozzle is fitted to each mouth and neck of the front and rear small containers respectively storing different kinds of liquids, and The nozzle of the outlet cap is formed in a semi-cylindrical shape with a rear opening, and the nozzle of the rear outlet cap is inclined obliquely upward and forward, and the outlet at the tip of the nozzle is disposed close to the upper rear of the nozzle of the front outlet cap. Then, by forming the different liquids discharged from both the front and rear small containers at the upper part of the nozzle of the front discharge cap, it is possible to obtain the required amount of the liquid mixture, and after the completion of the discharge, the mixed liquid is mixed. It was provided so as not to remain inside the container.

[0007] In addition to the above objects, the invention of claim 2 shown in Figs. 4 and 5 is formed so that the outside air for replacement can be supplied into the first and second small containers at the time of pour-out, and the same is achieved by its own weight. By forming so that a different amount of different liquids can be poured out, the different liquids can be surely mixed at a constant mixing ratio.
