Mechanism to prevent actuator of a pump dispenser to prematurely open and leak

The present invention is directed to a dispensing pump for dispensing material from a container comprising a chaplet comprising a rotating ring and a stationary ring, wherein the rotating ring is connected to an actuator and the stationary ring is connected to an actuator assembly; a rotating ring affixed to the actuator wherein the rotating ring comprises a cut-out arc having an angle between about 45 degrees to about 345 degrees, wherein the remaining portion of the rotating ring is an uncut portion; a stationary ring attached to the actuator assembly a key protruding from the stationary ring which fits along the cut-out arc of the rotating ring; wherein the actuator rotates with the rotating ring until the uncut portion of the rotating ring is stopped by the key wherein the actuator starts to unscrew from the rotating ring until the actuator is released. 本发明涉及种用于从容器分配材料的分配泵，该泵包括由旋转环和静态环构成的芯撑，其中旋转环连接到致动器，并且静态环连接到致动器组件；附连到致动器的旋转环，其中旋转环包括切割弧，该切割弧具有介于约45度至约345度之间的角度，其中旋转环的剩余部分是未切割部分；附接到致动器组件的静态环，从静态环突出的键，该静态环沿
