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.

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 psig 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.

Disclosed is a mold for forming a deep grip container, the mold having drive mechanisms opposably to drive moveable inserts into the mold. The drive mechanisms may be located entirely within the mold and may include a slotted cam. Also disclosed is a method of manufacturing a blow molded bottle with a deep pinch grip comprising: providing a mold hanger having an outer envelope and providing within the outer envelope a drive mechanism to drive moveable inserts into the mold after blowing molten plastic into contact with the mold. Further disclosed is a blow molded bottle with a deep pinch grip manufactured according to the disclosed methods.

Bottle

Disclosed is a mold hanger for supporting a bottle mold in a blow 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.

Container

A plastic container includes a shoulder portion having an annular rib defined therein and a generally cylindrical main body portion having a longitudinal axis. At least one gripping recess is defined in the main body portion that has an oblong shape when viewed in front elevation and that is defined in part by a curved concave inner surface when viewed in side elevation. The gripping recess includes a plurality of horizontal indentations, each of which is sized to receive a finger of a consumer when the plastic container is being gripped by the consumer.
