The present disclosure relates to a fluid dispenser of a type having a housing in which a container filled with a fluid to be dispensed is removably received. The container incorporates a pump and an adapter assembly for securing the pump within an opening or fitment of the container and for removably securing the container within the housing. In another aspect, an improved push bar-type actuator is provided. In certain embodiments, an angled receptacle for receiving the pump and adapter receptacle is provided for ease of emplacing the container within the housing.

1. A dispenser for dispensing fluids from a collapsible container of a type having a pump attached thereto, the pump being of a type which is actuated by axial displacement of an outlet nozzle along a longitudinal axis of the pump, said dispenser comprising: a rear housing section adapted to be attached to a vertical wall;a front housing section pivotally attached to said rear housing section and movable between an open position and a closed position;a push bar pivotally carried on said front housing section;a generally U-shaped lever arm connected to said push bar, said lever arm having two spaced apart bearing members, each bearing member having a proximal end secured to said push bar and a distal end having a bearing surface bearing against the outlet nozzle and transmitting axial movement to the outlet nozzle in response to pivotal movement of said push bar when the pump is received in the nest, the bearing surface having a cammed shape such that a point of contact between the bearing surface is aligned with a centerline of the pump, wherein said point of contact remains substantially aligned with said centerline during pivotal movement of said push bar to reduce off-axis forces on the nozzle, the distal ends of said bearing members having an opening therebetween allowing the pump to pass therebetween when the pump is received in said nest and said front housing section is moved from the open position to the closed position, and wherein said push bar and said lever arm are moved out of operational contact with the pump when the pump is received in said nest and said front housing section is in the open position;a nest formed in the rear housing section for removably receiving the pump in an inverted orientation, said nest including an inclined slot for receiving a portion of the pump, said inclined slot inclined upward toward said front housing section at a first angle ranging from about 5 degrees to about 30 degrees relative to horizontal when said dispenser is mounted in a vertical, operational orientation, whereby the longitudinal axis of the pump is inclined rearward toward an upper end of said dispenser at a second angle ranging from about 5 degrees to about 30 degrees relative to vertical when said dispenser is mounted in a vertical, operational orientation; andsaid push bar having a manually depressible portion which extends in a generally vertical direction from a lower end of the front housing section when said dispenser is mounted in a vertical, operational orientation wherein, during operation, horizontal movement of a user's hand on the manually depressible portion is translated by said push bar and said lever arm into movement in the direction of the pump axis, wherein, the user's hand is moved into alignment with the outlet nozzle of the pump, thereby allowing one-handed operation by the user. 2. The dispenser of claim 1, wherein said first angle is about 7.5 degrees and said second angle is about 7.5 degrees. 3. The dispenser of claim 1, wherein the fluid to be dispensed is liquid soap. 4. The dispenser of claim 1, wherein the fluid to be dispensed is liquid soap admixed with air in the form of a foam. 5. The dispenser of claim 1, wherein the collapsible container includes a plurality of flexible sheets sealed along a periphery to define an interior of the collapsible container and a fitment defining an opening in said collapsible container. 6. The dispenser of claim 1, further comprising: the pump removably received in said nest. 7. The dispenser of claim 6, further comprising: an adapter assembly connecting the pump to the collapsible container; andsaid inclined slot removably receiving an enlarged diameter portion of the adapter assembly. 8. The dispenser of claim 6, further comprising: said pump having an inlet, an outlet, a main body, and a nozzle including a nozzle flange attached to the outlet, wherein said nozzle, nozzle flange, and longitudinal axis are coaxial;an adapter ring including a connector sleeve coaxially receiving said pump, said connector sleeve having a first axial end and a second axial end opposite said first axial end;said first axial end engaging a pump flange of the pump;a retaining ring including a fastener attachable to said first axial end, said retaining ring clamping said pump flange of the pump between said first axial end and said retaining ring;said retaining ring having an annular channel seating a spring between said pump and said nozzle flange; andsaid second axial end including a fastener attaching said second axial end to the collapsible container. 9. The dispenser of claim 8, wherein at least a portion of the main body of the pump is received within the collapsible container. 10. The dispenser of claim 9, further comprising: a spring coaxially received about said nozzle and having a first end seated in said annular channel of the retaining ring and a second end bearing against said nozzle flange and urging said pump to a closed position. 11. The dispenser of claim 10, further comprising: a cap removably attached to said retaining ring and covering said nozzle. 12. The dispenser of claim 8, further comprising: a dip sleeve defining an opening receiving said pump inlet and having one or more channels formed in a wall of said opening defining a flow passageway between the collapsible container and the pump inlet, said one or more channels displaced with respect to said longitudinal axis. 13. The dispenser of claim 8, wherein said adapter ring includes a flange adapted to be removably received in said inclined slot. 14. The dispenser of claim 13, further comprising: one or more flexible spring arms attached to said adapter ring flange; anda latch member on each of said one or more spring arms removably engaging the inclined slot when the pump is received in said nest. 15. The dispenser of claim 14, further comprising: each of said flexible spring arms including a protrusion which engages a complimentary feature within said inclined slot. 16. The dispenser of claim 15, wherein said protrusion has generally tapered shape which facilitates sliding movement of said protrusion past said complimentary feature in a first direction when a pump is placed in said nest and which resists sliding movement of said protrusion past said complimentary feature in a second direction opposite the first direction. 17. The dispenser of claim 8, further comprising: an annular sealing ring disposed between said pump flange and said first axial end.
