Cartridge for pump assembly carrying rasp
First Claim
1. A pump assembly for dispensing of a fluid and of particles of a solid material comprising:
- a fluid pump which in a cycle of operation draws the fluid through a fluid inlet and dispenses the fluid out a fluid outlet,a block of the solid material,a pump housing body,the fluid pump including a movable member mounted to the body for reciprocal movement relative the body parallel to an axis in the cycle of operation to draw and dispense the fluid,the block received axially between the body and the movable member presenting a first axially directed surface directed toward the movable member,a rasp member comprising a resilient finger member having a first end and a distal end,the first end of the finger member coupled to the movable member to move axially relative the axis with the movable member,the finger member extending from the first end axially away from the first end and radially outwardly from the axis to the distal end which carries an axially directed rasp surface directed axially toward the first axially directed surface of the block in opposition to the first axially directed surface of the block,the axially directed rasp surface and the first axially directed surface of the block biased axially into engagement with each other,in the cycle of operation, when the body and the movable member move axially toward each other, the finger member is axially compressed between the first axially directed surface of the block and the movable member and the finger member resiliently deflects between the first end and the distal end against an inherent bias of the finger member reducing the axial length between the first end and the distal end and moving the distal end radially outwardly,in the cycle of operation, when the body and the movable member move axially away each other, under the inherent bias of the finger member, the finger member deflects between the first end and the distal end increasing the axial length between the first end and the distal end and moving the distal end radially inwardly,wherein during the cycle of operation the rasp surface in engagement with the first axially directed surface of the block moves radially relative the first axially directed surface of the block disengaging particles of the solid material from the block at a location that the particles drop under gravity downwardly adjacent the fluid outlet.

Abstract
A pump assembly for generating and dispensing of particles of a solid material with or without dispensing of a fluid. The pump assembly preferably includes a fluid pump which in a cycle of operation draws the fluid through a fluid inlet and dispenses the fluid out a fluid outlet. The pump assembly carries a block of the solid material coalesced together and a rasp member, which during the cycle of operation, moves relative the rasp in engagement with the block whereby the rasp member disengages particles of the solid material from the block which particles drop under gravity downwardly adjacent the fluid outlet, for example, onto a user'"'"'s hand as in the case that the fluid is a hand cleaning fluid and the solid is a solid soap.
