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

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. 设想了一种具有配合为嵌套壳的内盖和外盖的防儿童开启封闭件。施加到封闭件的向下的力接合系列配合的凸耳和棘爪，以接合防儿童开启特征，同时薄壁和在壳的接合表面上的配合的、斜坡状的裙部提高了沿着预限定的圆周的周向强度，以避免封闭件和容器颈部上的螺纹的脱离/脱离接合。还可以提供可选的防拆封环，以及形成在内壳的顶部面板中的防燃烧通气孔。
