Abstract: A push button for powder aerosol has a push button body, a nozzle and a guide passage. The nozzle is formed in the push button body with a diameter in a range of 0.4 mm to 1.0 mm and a length in a range of 0.3 mm to 2.0 mm in communication with a stem of an aerosol container. The guide passage is formed in the push button body in continuation with an outer end of the nozzle in extending in a spraying direction of the nozzle and formed with a diameter of a range of 1.0 mm to 3.0 mm that is larger than the diameter of the nozzle and a length of a range of 3.0 mm to 20.0 mm for guiding the contents of the powder aerosol. The nozzle flows out the contents with diffusion suppressed, so that accurate application can be made to the limited range on aimed areas such as skins.

Abstract: A subdividing apparatus for aerosol container for aerosol contents includes a fixed amount chamber formed in an apparatus body disposed with a stem of the aerosol container, and a piston capable of pressing the aerosol contents introduced in the fixed amount chamber is slidably attached in the apparatus body. A subdividing nozzle that can spray the aerosol contents in the fixed amount chamber is formed as to connect with the apparatus body via a subdividing valve. With the subdividing apparatus, spraying in a fixed amount in a prescribed period can be done with multiple spraying operations from the subdividing nozzle to limit overuse of, e.g., medicines and cosmetics.

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: Disclosed herein is a valve device for an aerosol container, comprising a housing the upper end of which is fixed to the interior of a lid, a partition wall arranged in the housing and provided with an insertion hole, an upper chamber provided above the partition wall, a lower chamber provided below the partition wall, a stem vertically movably installed in the upper chamber and provided with a pressing part at its lower end, the upper end of said stem being biased and projected outward from the lid through a stem gasket, a change-over valve vertically movably installed in the lower chamber facing the pressing part situated at the lower end of the stem, and a flow path for small spraying, which is made in the change-over valve and communicates the upper chamber with the lower chamber, wherein the change-over valve is pressed against and biased toward a valve seat provided on the lower surface of the partition wall, whereby the communication of the upper chamber with the lower chamber is cut off except for thr

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.

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: The invention relates to a nozzle connected to an aerosol vessel 1 which has an obliquely-handling valve 3. When a finger piece 18 protruding sideways from the nozzle body 14 is pressed toward the aerosol vessel 1, the obliquely-handling valve 3 can be opened easily by lever action without requiring a strong force, and the aerosol contents can be discharged continuously from a discharge portion 17 onto a target area 27 through a discharge path 16 for a relatively long period of time, without tiring the finger of the user.

Abstract: A powder aerosol composition is obtained by first preparing a suspension consisting of a hydrophobic powdered substance having its pH adjusted to fall within the range 5 to 9, alcohol and water, adding, if required by the desired powder system, an intentional medicine and other auxiliary agents to the suspension and mixing the suspension with 5 to 40 wt % of a propellant in an aerosol container. The thusly produced composition has an improved safety in application, prevents flying properties, has an improved adhesion to the skin and can be produced inexpensively. Thus, the composition is best suited for use in applications such as baby powder, dry shampoo, water-eczema remedy and antiperspirant.
