mechanism 26 "for preventing undesired triggering of main trigger 21."
Foster teaches (column 1, line 34, to column 2, line 4) that:
An object of the present invention is to provide a child-resistant pump
dispenser which overcomes the disadvantages associated with conventional
pump dispensers. Another object is the provision of a pump dispenser having
child-resistant features which are not easily operated by a child, but which are
easily operated by an adult. A further object of the present invention is the
provision of a child-resistant pump dispenser which is capable of releasably
preventing movement of the trigger and pump mechanism. Yet another object of
the present invention is the provision of a child-resistant pump dispenser which is
relatively low in cost and which is relatively simple in construction.
In general, a child-resistant liquid dispenser of the present invention
comprises a dispenser body, a pump mechanism, a first locking mechanism, and
a second locking mechanism. The dispenser body has an fluid intake port and a
fluid discharge port. The pump mechanism is adjacent the dispenser body and
includes a moveable member. The moveable member is moveable relative to the
dispenser body between first and second positions along an axis. The pump
mechanism is configured to draw liquid into the intake port and discharge it
through the discharge port upon movement of the moveable member between its
first and second positions. The first locking mechanism is adjacent the pump
mechanism and dispenser body and is moveable between locked and unlocked
positions. The first locking mechanism is engageable with both the moveable
member of the pump mechanism and the dispenser body when the first locking
mechanism is in its locked position in a manner to prevent movement of the
