Fluid dispenser

1. A fluid dispenser comprising:

a pump assembly for receiving fluid to be dispensed and responsive to a displacement input to pump said fluid;

an elongated housing connected to said pump assembly and delivering said fluid from said pump assembly, said housing having a first portion extending from said pump assembly to a fluid delivery end and a second portion extending in an opposite direction from said first portion, said housing further including a pair of pivot journal points;

a handle pivotally connected to said housing, said handle having a pivot location, said pivot location being positioned on said second portion, wherein said handle having a pair of trunions receivable over said journal points to provide said pivotal connection;

a mechanical connection between said handle and said pump assembly for providing said displacement input when said handle is pivoted, so that a mechanical advantage is applied to said pump assembly; and

wherein said housing has a pair of circular openings co-axial with said journal points and said housing further comprises a flexible clip having a pair of circular recesses for receiving said trunions, said clip being removeably received in said handle so that said circular recesses are held in said housing openings, said clip being elastically deformable to permit said trunions and said handle to be removed from said housing.

2. Apparatus as claimed in claim 1 wherein said clip has ramped surfaces facing the end of the second portion of said housing for assembly of said handle onto said housing by pushing said trunions over said ramped surfaces and into said circular recesses.

3. Apparatus as claimed in claim 2 wherein said handle has an opening between said pivot and the free end of said handle.

4. The fluid dispenser of claim 3 wherein said pump assembly receives displacement input through an integral T-shaped element and wherein said foot is slotted to embrace said T-shaped element to provide bi-directional input to said pump assembly from said handle.

5. A fluid dispenser comprising:

a pump assembly for receiving fluid to be dispensed and responsive to a displacement input to pump said fluid;

an elongated housing connected to said pump assembly and delivering said fluid from said pump assembly, said housing having a first portion extending from said pump assembly to a fluid delivery end and a second portion extending in an opposite direction from said first portion;

a handle pivotally connected to said housing, said handle having a pivot location positioned on said second portion;

a mechanical connection between said handle and said pump assembly for providing said displacement input when said handle is pivoted, so that a mechanical advantage is applied to said pump assembly, said mechanical connection comprising a foot affixed to said handle and adapted to abut said pump assembly for displacement thereof, wherein said housing having an opening therein for receiving said foot to transfer displacement of said handle to said pump assembly, wherein said pump assembly having a substantially flat head for receiving said displacement input and wherein said foot having a curved surface for abutting said flat head whereby side loads on said pump assembly ale minimized; and

wherein said foot has curved side walls extending into said hole in said housing and a lip adjacent the curved pump assembly contacting surface for limiting pivoting movement of said handle away from said pump assembly by abutting said hole, said curved side walls having an end bevel cooperating with said lip to permit removal of said handle and foot from said housing only when said lip abuts said hole.

6. A fluid dispenser comprising:

a pump assembly having a base and a plunger having a fluid outlet end and being reciprocable to pump fluid to said fluid outlet end;

an elongated housing having a fluid outlet end and connected to said base, the outlet end of said plunger being positioned within and reciprocable in said housing,

a handle pivotally connected to said housing;

a mechanical connection between said plunger and handle for providing said reciprocal displacement when said handle is pivoted so that a mechanical advantage is applied to said pump assembly;

a flexible tube connecting the fluid outlet end of said plunger to the fluid outlet end of said housing whereby when said handle is pivoted, said fluid is delivered from said housing at a position unaffected by displacement of said plunger; and

wherein said pump assembly base has a circular configuration and said housing comprises:

upper and lower halves connected to each other at an overlapping joint, each half having a semicircular opening to embrace the circular configuration of said pump assembly base when said halves are connected to each other.

7. The fluid dispenser of claim 6 wherein said upper and lower halves have a flange at said semicircular opening; and said apparatus further comprises a collar releasably connected to the pump assembly base and overlapping said flanges to maintain said upper and lower housing halves together.

8. The fluid dispenser of claim 7 for use with a fluid container having a generally planar top to which said dispenser is affixed, said top having a circular opening corresponding to the circular configuration of said base, said base and circular flanges of said halves being inserted through said opening and wherein said base has threads and said collar has corresponding inwardly-facing threads to releasably connect said dispenser to said planar top.

9. The fluid dispenser of claim 8 wherein said threaded collar has a pair of wings radially extending therefrom to facilitate threading and unthreading of said collar.

10. The fluid dispenser of claim 6 wherein said housing further comprises an outlet having a passage therethrough fluidly connected to said flexible tube, said outlet overlapping the upper and lower halves of said housing near the delivery end thereof to maintain the housing halves together.
