1. A liquid dispenser (10) for dispensing a fluid (80), comprising:

  • a. a housing (20) having a height H and a central axis AA extending between side walls 43 parallel to a housing bottom floor (44) and disposed at the midpoint of the housing height H;

    wherein the housing includes a first housing wall (22), a second housing wall (42) opposite the first housing wall (22), a shaped inner frame (90) having a first inner frame side (92) and a shaped outer frame (24);

    wherein the outer frame (24) connects the first housing wall (22) with the second housing wall (42);

    b. wherein the housing contains a pump (26) configured for pumping the fluid (80), wherein the pump (26) is connected to a pump inlet conduit (28) and a pump outlet conduit (30);

    c. wherein the housing (20) contains a refill bay (70) defined by the shaped inner frame (90) and configured to receive a refill (60) comprising a refill reservoir (40) and a refill adapter (50) that is inserted into the refill bay (70) through the first inner frame side (92) at the rear of the dispenser along either the vector R or R′

    wherein the vector R and the vector R1 are both in the same plane defined by the height H and the axis AA and wherein both vectors intersect the central axis AA on opposite sides at a point midway between the first housing wall (22) and the second housing wall (42);

    wherein the vector R intersects the central axis AA at an angle α

    between 0 and 75 degrees and the vector R′

    intersects the central axis AA at an angle α



    between 0 and minus 75 degrees; and

    d. wherein the refill (60) includes an outlet interface (48) in fluid communication with the refill reservoir (40) and wherein the outlet interface (48) and a pump inlet conduit interface (53) are configured to sealingly engage with each other when the refill (60) is fully inserted into the refill bay (70),and wherein the refill is substantially surrounded by the outer frame,and wherein the refill (60) passes into the refill bay (70) on the opposite side of the dispenser (10) from where a dispenser outlet (12) is located, the dispenser outlet being located at the front of the dispenser.
