Abstract
In a liquid dispenser, the pump plunger having a discharge head thereon is locked to the closure cap on a liquid container against relative displacement. A pair of opposed locking elements, attached to the side wall of the discharge head, each having a locking pawl thereon for engagement with inwardly extending lip portions provided on the cap. The locking elements are spring biased into locking engagement, and are capable of being manually moved from a locking position to an unlocking position in which the locking pawls are out of engagement with the lip portions. When out of engagement, the locking elements are retained in their unlocking position to avoid any interference between the locking pawls and the annular lip during plunger reciprocation.
