Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
A chewing gum stick having a thickness within the range of from about 1250 to about 2300 microns and having solid flavor particles printed on at least one surface thereof, said flavor particles penetrating the surface thereof to a depth of within the range of from about 35 to about 230 microns, the interior of the stick being substantially free of flavor particles, said flavor particles providing an amount of flavor within the range of from about 0.14 to about 0.54% by weight of said stick.
Claim 2
Dependent Claim
86 words
A chewing gum stick having a thickness within the range of from about 1250 to about 2300 microns and having solid flavor particles printed on at least one surface thereof, said flavor particles penetrating the surface thereof to a depth of within the range of from about 35 to about 230 microns, the interior of the stick being substantially free of flavor particles, said flavor particles providing an amount of flavor within the range of from about 0.14 to about 0.54% by weight of said stick.
Claim 3
Dependent Claim
15 words
A chewing gum stick according to claim 1 wherein the solid flavor particles are microencapsulated.
Claim 4
Dependent Claim
24 words
A chewing gum stick according to claim 1 wherein the microencapsulated flavor particles have a size of from about 1 to about 100 microns.
Claim 5
Dependent Claim
24 words
A chewing gum stick according to claim 3 wherein the microencapsulated flavor particles have a size of from about 1 to about 50 microns.
Claim 6
Dependent Claim
20 words
A chewing gum stick according to claim 1 wherein the solid flavor particles comprise flavors sorbed on an edible substrate.
Claim 7
Dependent Claim
26 words
A chewing gum stick according to claim 1 having solid flavor particles impregnated on both the top and the bottom surface of the chewing gum stick.
Claim 8
Dependent Claim
25 words
A chewing gum stick according to claim 1 wherein the solid flavor particles penetrate the surface thereof to at most 35 to about 45 microns.
Claim 9
Dependent Claim
110 words
A method for preparing a chewing gum stick according to claim 1, which comprises rolling and scoring a mass of chewing gum composition to form sticks of gum, feeding a stick of chewing gum between two cylinders, at least one of the cylinders comprising a printing cylinder having from about 3 to about 120 lines/cm and a cell depth of from about 20 to about 230 microns, said printing cylinder applying a slurry of solid flavor particles to at least one surface of the chewing gum stick, said flavor particles providing an amount of flavor within the range of from about 0.14 to about 1.54% by weight of said stick.
Claim 10
Dependent Claim
22 words
The method as defined in claim 8 wherein the slurry of solid flavor particles comprise an aqueous slurry of microencapsulated flavor particles.
