  • Patent number: 10442604
    Abstract: A plastic aerosol container includes a main body portion that is constructed and arranged to withstand aerosol pressurization within a range that is about 50-300 psig. The plastic aerosol container also includes a finish portion that is unitary with the main body portion. The finish portion may be threaded or unthreaded. The finish portion has a side wall, an upper sealing surface, at least one helical thread and a support ledge beneath the helical thread. Reinforcement structure is positioned beneath the support ledge for reinforcing the finish portion against deformation due to the pressurization. A method of stabilizing a plastic aerosol container is also disclosed.

  • Publication number: 20190152683
    Abstract: An aerosol container includes a main body portion that is constructed and arranged to withstand aerosol pressurization within a range that is about 90-180 prig and a threaded finish portion that is unitary with the main body portion. The threaded finish portion has at least one helical thread, a support ledge beneath the helical thread and a secondary flange that is positioned beneath the support ledge. The secondary flange has an outer circumference that is noncircular in at least one location, whereby it may be engaged during a capping operation to prevent rotation of the container during capping. A method of making an aerosol container in which a preform is capped before the blow molding process is also disclosed.

  • Publication number: 20160236397
    Abstract: Mold hanger for supporting a bottle mold in a molding station, the mold hanger comprising a piston and piston sleeve fully contained within the mold hanger configured to push a moveable insert into the mold. Also disclosed is a method of retrofitting an original rotatable blow molding module having multiple existing blow molding stations, each existing mold hanger defining an existing outer envelope. The disclosed method may include providing an improved mold hanger substantially contained within the respective existing outer envelope and including low-profile drive mechanisms configured opposably to drive moveable inserts into the mold. Further disclosed is a method of manufacturing a blow molded bottle with a deep pinch grip, the method including providing within a mold hanger a drive mechanism to drive a moveable insert into the mold. A bottle made by such methods is also disclosed.

  • Patent number: 8962114
    Abstract: A compression molded preform for forming an invertible base hot-fill container, and systems and methods thereof. The preform includes a body with a first open end, a second closed end or end cap of hemispherical shape, and a sidewall extending between the first end and the second end. At least a portion of the second end is thinner than any portion of the sidewall. Further, the second end is gateless and has an inner surface that is substantially smooth along its entire area. The compression molded preform is blow molded to form a plastic container with an invertible or movable base. The invertible or movable base is responsive to, or can be moved based on, internal forces or pressure associated with processing the container with a filled product.
