US Patent 6877642 Wall-mounted dispenser for liquids

A dispenser for dispensing liquid from a collapsible bag has a back plate and a cover hingedly attached thereto for movement between open and closed positions. The back plate carries a bag retainer and pump support which receives the bag which, in turn, carries a collapsible dome-type pump on its front surface adjacent its bottom edge. The pump includes a transparent collapsible dome and the dispenser cover includes a push bar for collapsing the dome to expel material. The push bar also has a clear window overlying the collapsible dome when the cover is closed.
