LIGHTWEIGHT, CHILD RESISTANT CLOSURE WITH TAMPER EVIDENT, COMBUS-TION RESISTANT, AND/OR STRIP-TORQUE RESISTANT FEATURES

摘要

A child-resistant closure having inner and outer caps cooperating as a nested shell is contemplated. Downward force applied to the closure engages a series of cooperating lugs and detents to engage the child resistant feature, while thinned walls and cooperating, ramped skirts on the shells' interfacing surfaces to improve the hoop strength along a predefined circumference to avoid stripping/disengagement of the threads on the closure and container neck. An optional tamper evident ring may also be provided, as well as a combustion resistant vent formed in the top panel of the inner shell.
