Description

Aerosol spray for drain cleaning [0002]

The present invention relates to an aerosol spray for cleaning a drain pipe, and more particularly, to an aerosol spray for a drain pipe cleaning which is excellent in foam cleaning effect by spraying a drain pipe cleaning composition to a sink drain hole and a drain pipe.

The drainage pipe and the drain pipe of the sink are food which remains in the process of cooking or throwing out food, and it is always wet in water and the microorganism is easy to grow, which makes it easily messy and causes a bad smell. However, it is inconvenient, time-consuming and labor-intensive to clean the sewer or drain line to keep it clean, which is problematic because there is no special alternative to the method of replacing the drain line or the drain line.

To solve this problem, U.S. Patent Application No. 2014-529388 discloses a two-component system in which hydrogen peroxide is foamed with a hydrolytic enzyme such as amylase to clean the piping. However, such a system is disadvantageous in that the bactericidal bleaching power of hydrogen peroxide is significantly lower than that of sodium hypochlorite, so that the bactericidal bleaching effect is not sufficiently exhibited.

In addition, U.S. Patent Application Publication No. 2003-0171234 discloses a method in which a sodium hypochlorite composition having a viscosity and a foaming agent are poured at the same time and foamed to clean the pipe. However, in such a cleaning method, sodium hypochlorite and the foaming agent are difficult to uniformly mix, and there is a limit to maintain the cleaning power because the foam is not discharged for a long time to the vertically installed pipe of the sink. Therefore, it is necessary to develop a composition or a method capable of cleaning the sink drain pipe more effectively by increasing the duration of the cleaning effect of the foam cleaning composition.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an aerosol spray for cleaning a drain pipe that can be sprayed on a sink drain and a drain pipe to exhibit a foam cleaning effect.

The ejection time of the aerosol spray of the present invention can be adjusted to eject the detergent composition for about 1 to 10 minutes, preferably 1.5 to 8 minutes, more preferably 2 to 5 minutes. If the ejection time is less than one minute, the foamed detergent composition may be insufficient to fill the drain hole and the drain pipe. If the ejection time is more than 10 minutes, the detergent composition may be unnecessarily overdischarged.

In order to sufficiently exhibit the cleaning effect, the discharged foamed detergent composition can be left in the drain and drain pipes for 10 minutes to 180 minutes, preferably 20 minutes to 150 minutes, more preferably 30 minutes to 120 minutes. If the cleaning time is less than 10 minutes, the cleaning agent composition does not stay for a long time and the cleaning effect is insufficient. When the cleaning agent composition is used for more than 180 minutes, the cleaning time is unnecessarily increased, Problems can arise.

In addition, the present invention provides a method for cleaning a drain hole and a drain pipe using an aerosol spray for cleaning the drain pipe.

Preferably, in the cleaning method of the present invention, the aerosol spray for cleaning the drain pipe is combined with the inlet of the drain hole to allow the cleaning agent to be discharged for a predetermined time (FIG. 1).
