Abstract
A non-barrier type aerosol container (10) dispensing a fluent material. A generally cylindrical can body (12) has a relatively thin sidewall thickness of between 0.004 inches and 0.010 inches depending upon the type of metal from which the container is made. The can body has beads (30) formed at regular intervals substantially its length. The beading adds structural strength to the container so the container is not readily deformed when un-pressurized. The aerosol container also can withstand a vacuum of at least 23 inches of Mercury without collapsing. A valve assembly (14) includes a spray valve (20) for dispensing the fluent material stored in the container. The container is filled with the fluent material and a propellant stored in the container under pressure.
Claims28
A non-barrier type aerosol container for dispensing a fluent material comprising:
- a generally cylindrical can body having a relatively thin sidewall thickness, the can body being a beaded can body having beads formed substantially the entire length thereof from one end of the container to the other with the beading adding structural strength to the container so the container is not readily deformed when subjected to a vacuum during filling with the fluent material, or other external forces;
- and,
- a valve assembly for dispensing the fluent material stored in the container, the container being filled with the fluent material and a propellant therefore, the fluent material and propellant being stored in the container under pressure.
A non-barrier type aerosol container for dispensing a fluent material comprising:
- a generally cylindrical can body made of steel and having a sidewall thickness of between 0.004 inches (0.102 mm) and 0.008 inches (0.205 mm), the can body being a beaded can body having beads formed substantially along the entire length of the can body from one end of the container to the other, the beading adding structural strength to the container so the container is not readily deformed when subjected to vacuum during filling with the fluent material, or other external forces;
- and,
- a valve assembly for dispensing the fluent material stored in the container, the container being filled with the fluent material and a propellant therefore which are stored in the container under pressure.
A non-barrier type aerosol container for dispensing a fluent material comprising:
- a generally cylindrical can body made of aluminum and having a sidewall thickness of between 0.004 inches (0.102 mm) and 0.010 inches (0.255 mm), the can body being a beaded can body having beads formed substantially along the entire length of the can body from one end of the container to the other, the beading adding structural strength to the container so the container is not readily deformed when subjected to a vacuum during filling with the fluent material or other external forces;
- and,
- a valve assembly for dispensing the fluent material stored in the container, the container being filled with the fluent material and a propellant therefore which are stored in the container under pressure.
A process for dispensing a fluent material from an aerosol container comprising:
- forming an aerosol container having a generally cylindrical can body of a relatively thin sidewall thickness, the can body being a beaded can body having beads formed substantially the entire length of the can body from one end of the container to the other, the beads adding structural strength to the container so the container does not readily deform when subjected to a vacuum or external forces;
- fitting a valve assembly to one end of the can body, the other end of the can body being closed, the valve assembly including a spray valve for dispensing the fluent material;
- and,
- filling the container with the fluent material and a propellant for dispensing the fluent material, the fluent material and propellant being stored in the container under pressure.
