Abstract: 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.

Abstract: A double chamber aerosol container has a soft elastic inner sack, mounted within a metal container body, and a housing mounted to a top end of an inner periphery of the inner sack. The inner sack is in contact with special sized temporarily fitting portion as well as insertion contact portion of the housing to prevent the propellant from leaking out. Where an inner diameter of the top end of the inner periphery of the inner sack is 1, the outer diameter of an insertion contact portion of the housing is set to 1.02 to 0.98, the maximum outer diameter of the temporarily fitting portion is set to 0.97 to 0.95, the minimum outer diameter of the temporarily fitting portion is set to 0.94 to 0.88, and the minimum portion is formed below the maximum portion as well as the width in the up and down directions of the temporarily fitting portion is set to 0.19 to 0.10.

Abstract: 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.

Abstract: In a flow controller mounted in a valve assembly for aerosol container, a stem body and a piston are inserted in a housing of the valve assembly in placing a spring between the stem body and the piston. The piston is formed with a controlling sleeve at a bottom of which an introduction hole for flowing the aerosol contents is opened in the piston. The controlling sleeve can enter into an insertion space formed between a cylinder formed at the stem body and an insertion member. Inner and outer round passageways capable of communicating with one another, are formed between the inner round surface of the controlling sleeve and the outer round surface of the insertion member and between the outer round surface of the controlling sleeve and the inner round surface of the cylinder, respectively.

Abstract: A double-walled aerosol spray container includes a hollow outer jacket and a flexible bag therein. A substance to be sprayed is held in the bag, while a propellant is charged into a space outside of the bag and within the jacket. The construction of the aerosol spray container helps ensure that the bag does not slip off during manufacture or use thereof. The bag includes a flange about its open end, and the flange abuts an inwardly projecting engagement ridge formed on a corresponding part of the jacket, preferably with an annular packing therebetween. The bag has a storage section that is thinner than the flange, and is easily deflatable or deformable. The aerosol spray container also includes a housing in which a spray valve mechanism is incorporated. The housing includes an inner frame that is inserted into the open end of the bag so that the bag is securely held between the jacket and the housing.

Abstract: 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.
