Abstract
A dip tube whose tip portion can reach the nooks at the bottom of an aerosol container, so that the aerosol content therein can be assuredly sprayed with substantially no aerosol content being left unused. A weight fixed around the dip tube is arranged so that it does not hit the inner surface of the aerosol container. The dip tube is provided in an aerosol container and an end portion thereof is connected to a valve mechanism. The opposite end of the dip tube is left free. The dip tube conveys the aerosol content from the container to the valve mechanism where it is emitted as an aerosol spray. The dip tube includes a pliable tube main body and a tubular weight fixed on the tube main body adjacent to the free end. An end portion of the tube main body is therefore left exposed by the tubular weight. The length of the exposed end portion is selected so that the end portion is assuredly interposed between the weight and the interior surface of the container.
