A locking mechanism, a dispensing pump assembly, a container system and a method for using the same

Abstract

The present invention relates to a locking mechanism, a dispensing pump assembly, a container system and a method for using the same. A locking mechanism for a dispensing pump comprises: a movable button actuatable by a user to move between an initial position and a pressed position; a slidable switch embedded in the button, being actuatable by the user to move between an open position and a close position, such that the locking mechanism changes between an unlocking state and a locking state; and a rotatable annular member cooperating with the switch, which can be actuated by the switch such that a sliding movement of the switch causes rotation of the annular member, wherein: when the locking mechanism is in the unlocking state, the annular member allows the user to actuate the button so as to enable a dispensing; and when the locking mechanism is in the locking state, the annular member prevents the movement of the button so as to prohibit the dispensing.
