Dispensing of fluent materials
First Claim
1. A dispensing device for use in dispensing measured quantities of fluent material through a resiliently compressible dispensing tube, the device comprising a housing having a compression zone and a cartridge zone for removably receiving a unitary cartridge having a dispensing tube engaged therethrough, collapsing means located in the cartridge zone in said compression zone for collapsing said tube, and displacement means for displacing the collapsing means to advance the compression zone along a compression path to dispense fluent material through the tube;
- and,adjustment means, including an adjustable cam member to cooperate with the collapsing means and control the effective length of a compression path during operation of the collapsing means.

Abstract
A dispensing device for use in dispensing measured quantities of fluent material through a resiliently compressible dispensing tube, the device comprising a housing having a cartridge zone for receiving a cartridge having a dispensing tube associated therewith, collapsing structure adapted to be rotatably driven for collapsing a tube located in the cartridge zone in a compression zone, and drive structure for rotatably driving the collapsing structure to displace the compression zone along a compression arc to dispense fluent material through the tube. A dispensing kit comprising a dispensing device as described, a cartridge receivable in the cartridge zone, and a resiliently compressible dispensing tube associated with the cartridge, with the tube having its trailing end connected to a collapsible fluent material container, and having its leading end connected to a dispensing member. A fluent material pack comprising a cartridge receivable in a cartridge zone of a dispensing device, and a resiliently compressible dispensing tube associated with the cartridge; and a cartridge for use with the dispensing device, the cartridge being adapted to have a resiliently compressible dispensing tube associated therewith.

17. A dispensing device for use in dispensing measured quantities of fluent material through a resilient dispensing tube, said device comprising:
-
a housing having; a base wall; a peripheral wall extending at least partially about the edge of said base wall, and, a front wall extending from said base wall; said base wall, said peripheral wall and said front wall defining an open chamber; a rotatable member having an annular section and a bearing section, said bearing section rollably engaging said housing and supporting said annular section for rotation in said chamber; drive means for driving said annular section in said chamber; the peripheral wall of said annular section spaced apart from said housing peripheral wall to define a compression zone therebetween; and
,a compression member projecting from said annular section into said compression zone toward said housing peripheral wall; wherein said annular section includes; an aperture extending substantially radially through said annular section wall for receiving said compression member; cooperative means disposed in said aperture and on said compression member for holding said compression member in said aperture.

18. A dispensing device for use in dispensing measured quantities of fluent material through a resilient dispensing tube, said device comprising:
-
a housing having; a base wall; a peripheral wall extending at least partially about the edge of said base wall; and
,a front wall extending from said base wall; said base wall, said peripheral wall and said front wall defining an open chamber; a rotatable member having an annular section and a bearing section, said bearing section rollably engaging said housing and supporting said annular section for rotation in said chamber; drive means for driving said annular section in said chamber; the peripheral wall of said annular section spaced apart from said housing peripheral wall to define a compression zone therebetween; and
,a compression member projecting from said annular section into said compression zone toward said housing peripheral wall; further including a cam member disposed within the open, center portion of said annular section and operatively engaging said compression member; said cam member having a cam surface cooperatively engaging said compression member over a selectable portion of the rotation of said rotatable member. - View Dependent Claims (19)

20. A dispensing device for use in dispensing measured quantities of fluent material through a resilient dispensing tube, said device comprising;
-
a housing having; a base wall; a peripheral wall extending at least partially about the edge of said base wall; and
,a front wall extending from said base wall; a base wall, said peripheral wall and said front wall defining an open chamber; a rotatable member having an annular section and a bearing section, said bearing section rollably engaging said housing and supporting said annular section for rotation in said chamber; drive means for driving said annular section in said chamber; the peripheral wall of said annular section spaced apart from said housing peripheral wall to define a compression zone therebetween; and
,a compression member projecting from said annular section into said compression zone toward said housing peripheral wall; a cartridge including a body portion having a bore through a central portion thereof; a cartridge compression wall extending from said body portion generally concentrically aligned with said bore; said cartridge adapted to be disposed in said chamber with said compression wall disposed in said compression zone so that said compression member extends into said compression zone toward said compression wall; a resilient, compressible dispensing tube disposed in said cartridge in position for compression against said compression wall by said compression member, said compression member rotating with said rotatable member; wherein said cartridge compression wall includes a flange extending therealong and wherein said tube includes a tab extending axially therealong and adapted to be disposed in said compression wall flange; an annular clamp for holding said tab in said compression wall flange; the outward edge of said compression wall flange having a rim; a locking ring cooperatively engaging said rim for holding said clamp in place in said compression wall flange whereby, through the cooperative action of said clamp, locking ring and tab, said tube is held in position in said cartridge. - View Dependent Claims (21, 23)
