Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a liquid discharger, and more particularly, to a liquid discharger that can mix and discharge two kinds of liquids and includes a comb-shaped discharger.
[0002]
[Prior art]
As a liquid discharger, the stem protrudes from the upper surface so that it can be pushed down in an upward biased state, and when the stem is pushed in, the built-in discharge valve opens, and an aerosol container body configured to discharge liquid by gas pressure is fitted to the stem. What consists of a discharge tool is known. The discharge tool generally has a discharge hole on the front surface and is configured to be fitted to the tip of the stem to discharge the liquid forward, but a comb-type discharge tool having comb teeth is also known. . For example, these are configured by protruding comb teeth on the front surface of a long extraction tube fitted to a stem and opening a discharge hole in the extraction tube at the base end portion of the comb teeth.
[0003]
Dischargers equipped with these comb-shaped dischargers are mainly used for hair cosmetics, etc., but some of these cosmetics are used by mixing two liquids at the time of use, for example, hair dyeing. Generally, these mixed liquids have high viscosity. After these mixed liquids are discharged through the discharge tool, a part of the liquid may remain attached to the discharge tool, and there may be a problem that smooth discharge cannot be performed when it is used again.
[0004]
Since the conventional comb-type dispenser of this type of dispenser does not consider removal, it is troublesome to remove it even if it is to be cleaned, and there is a risk that it will be forcibly broken. Further, even when it is safely removed, there is a disadvantage that sufficient cleaning cannot be performed because the flow path of the mixed liquid is inside.
[0005]
[Problems to be solved by the invention]
The present invention provides an excellent liquid discharger that can be easily removed by disassembling and disassembling a comb-type discharge tool, and can be easily detached from the container body at that time, and does not have a risk of disconnection during use. It is what we propose. The present invention also proposes a liquid ejector that is extremely easy to disassemble after removal. Furthermore, the present invention proposes a liquid ejector that can prevent inadvertent leakage of liquid at all times and can eject the mixed liquid satisfactorily by a simple operation during liquid ejection.
[0006]
