A double chamber aerosol container capable of filling contents in the container has a container cap that constitutes a liquid container with an inner sack to be temporarily fitted to a bead portion of an outer container while the inner sack is placed within the outer container. When the inner sack is placed with the outer container, the lower end of the inner sack is not in contact with the bottom of the interior of the outer container. The propellant is filled in the outer container upon forming a filling gap between the container cap and the bead portion, and then the container cap is surely clinched to the bead portion of the outer container.

Double chamber aerosol container and manufacturing method therefor

A double chamber aerosol container capable of filling contents in the container upon cutting off open air has an inner sack, whose volume is reducible according to reduction of contents, formed with temporarily engaging portions. A housing to which a valve assembly is arranged is inserted in the inner sack where the temporarily engaging portions are temporarily engaged with a ring-shaped neck portion of an outer container. After propellant is filled in a space between the inner sack 1 and the outer container during this temporarily engagement, the inner sack is inserted in the outer container to form the double chamber aerosol container.

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.

Effective application of enough of the contents of an aerosol container to carpets and floor coverings to give thorough extermination of insects and mites infesting such floor coverings is accomplished by the method of this invention, comprising the steps of leading the contents from a stem to an applicator part formed on a lateral side of the aerosol container and allowing the contents to exude from an application face of the applicator part. This method is worked advantageously by an application type aerosol apparatus which comprises an applicator prop disposed in the vertical direction on the outside of the aerosol container, having the applicator part fixed in the longitudinal direction on the outer surface thereof, having a guide chamber for the contents of the aerosol solution formed on the inner surface of the applicator part and a guide inlet communicating with the stem of the aerosol container connected to the applicator prop and adapted to enable the incoming contents to exude from the outer surface of the applicator prop.
