Or household products such as detergents and laundry finishes are used.

As a component of the content liquid, a component that exhibits a liquid state at room temperature does not cause solidification in the nozzle.
However, at room temperature, the components that are essentially solid, viscous liquid, and paste are all solidified and cause clogging.
For example, these components include surfactants, polymers, organic or inorganic insoluble powders, higher alcohols, inorganic and organic salts, organic or inorganic pearlizing agents, and clouding agents.

In addition, each component is liquid at room temperature, but solidified, viscous liquid, or pasty as a result of chemical reaction or ionic or hydrophobic bond interaction in the product. Cause.
When the amount obtained by removing water from the composition is called a solid component, if the solid component exceeds 10% of the total composition, solidification is likely to occur in a nozzle or the like, and solidification is likely to occur particularly in a thin nozzle or the like.

  Further, the polymer promotes the occurrence of solidification, and is particularly remarkable in the case of a composition in which the solid component exceeds 10% of the total composition and the polymer is blended.

  In the liquid discharger of the present invention, even when the solid component exceeds 10% of the total composition and a polymer is blended as the content liquid, the discharge port portion 26 is rotated upward after the content liquid is discharged. Thus, the content liquid adhering to the inside of the discharge port portion 26 and the flow path 24a of the nozzle base 24 can be removed and kept clean, so that clogging in the nozzle can be prevented.

  In addition, even if the content liquid remains in the flow path 24a of the nozzle base 24 and solidifies to cause clogging, the discharge port portion 26 can be opened upward before use of the liquid discharger so that it can be easily cleaned. Even easy-to-use liquids can be used without problems.

Next, as examples of liquid cosmetics, examples are given for hair styling and liquid soaps that are often used, and their components are described.
