带有阀防移除特征结构的预成型件
摘要：
本发明公开了一种适于吹塑成可用于加压气溶胶分配器(20)的外容器(22)的预成型件(60)。预成型件(60)具有纵向轴线和封闭端底部、开口颈部(24)。颈部(24)具有用于接收具有互补螺纹(25)的阀(28)的螺纹(25)。至少一个棘爪(74)或棘轮(73)与预成型件(60)的周边操作地并置。至少一个棘爪(74)或棘轮(73)允许互补阀(28)沿向前方向向前旋转并且防止阀(28)沿反向旋转方向脱离。可将任何这样的预成型件(60)吹塑成相应的外容器(22)，并且任何这样的外容器(22)可由相应的预成型件(60)吹塑而成。
摘要（英）：

A threaded valve (28) for an aerosol container (22). The threaded valve (28) comprises a housing (28H), a moving assembly (28M) disposed in the housing (28H), threads (25) suitable for threadable onward attachment onto a complementary neck (24) of an outer container (22) for an aerosol dispenser and a plurality of pawls (74) and/or ratchets (73) disposed on and extending from the housing (28H). The pawls (74) and/or ratchets (73) allow onward rotation of the valve (28) onto the complementary neck (24) and impeding rotational detachment of the valve (28) in a reverse direction.
