Dispensing of fluent materials
First Claim
1. A dispensing device for use in dispensing measured quantities of fluent materials through a plurality of resiliently compressible dispensing tubes, the device comprising:
- a housing having a tube zone for receiving a plurality of dispensing tubes;
collapsing means for collapsing, in compression zones, dispensing tubes when located in the tube zone;
said collapsing means including a plurality of displaceable compression members slideably connected to said collapsing means and projecting beyond the periphery thereof;
displacement means for displacing the collapsing means to advance the compression zones along compression paths to dispense fluent materials through said dispensing tubes;
a plurality of independently adjustable cam members adapted to cooperate with the respective compression members to control the effective length of the compression paths during operation of the collapsing means.

Abstract
A dispensing device for use in dispensing measured quantities of fluent materials through a plurality of resiliently compressible dispensing tubes, the device comprising a housing having a tube zone for receiving a plurality of dispensing tubes; collapsing device for collapsing, in compression zones, dispensing tubes when located in the tube zone; displacement device for displacing the collapsing device to advance the compression zones along compression paths to dispense fluent materials through such dispensing tubes; and adjustment device for adjusting the effective length of at least one of the compression paths effected by the collapsing device during displacement thereof. A dispensing kit comprising a dispensing device as described, and a plurality of resiliently compressible dispensing tubes for location in the tube zone.

8. A dispensing kit comprising:
-
a dispensing device for use in dispensing measured quantities of fluent materials through a plurality of resiliently compressible dispensing tubes, said device including a housing having a tube zone for receiving a plurality of dispensing tubes and having a removable cover plate for the tube zone; a flange connecting said dispensing tubes together; collapsing means for collapsing, in compression zones, said dispensing tubes when located in said tube zone; displacement means for displacing the collapsing means to advance the compression zones along compression paths to dispense fluent materials through said dispensing tubes; adjustment means for adjusting the effective length of at least one of the compression paths effected by the collapsing means during displacement thereof; a plurality of a resiliently compressible dispensing tubes for location in said tube zone; said cover plate having at least one securing flange to cooperate with the walls defining the tube zone for securing said dispensing tubes in position in said tube zone; at least one of said tubes having an engagement flange for location between the securing flange of the cover plate and the walls defining the tube zone, for locating the tubes in position in the tube zone. - View Dependent Claims (9, 10, 11, 12, 13)
