Abstract

An antiseptic soap dispenser (A) is mounted to a wall by a secure mounting system (E). A latching and locking mechanism (D) inhibits tampering with the dispenser or theft of a replaceable soap reservoir (B), received within a dispenser housing (C). The housing includes a front cover (18) pivotally connected to a back plate (20). The mounting mechanism (E) removably mounts the back plate of the housing to a wall mounting plate (24), which is attached by screws or other fixing means to a wall or other suitable mounting surface. The back plate includes mounting tabs (172) which engage a corresponding releasable engagement portion (170) on the mounting plate to secure the housing to the mounting plate. A latch plate (60), is movably carried by the back plate. The latch plate provides the latching and locking mechanism (D) which releasably locks the housing in a manner which is not readily obvious to a casual observer, yet which avoids the need for a key. The latching and locking mechanism (D) secures the front cover to the back plate. The latch plate includes a plurality of latching hooks (80) which engage tabs (90) on an interior of the front cover. The latching hooks are moved downward, and out of engagement, by pressing upward on a push bar (78) mounted to a lower end of the latch plate. A locking plate (110), pivotally connected to the latch plate, provides an optional additional locking system when pivoted to a position in which downward motion of the latch plate is prevented.
