Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
63 words
A substantially anhydrous, non-staling chewing gum composition, which comprises: a two component composition, the first being a homogenous premixture of about 10 to about 60% of a chewing gum base and about 2 to about 20% of a polyisobutylene having an average molecular weight of about 20,000 to about 100,000, a second component being about 38% to about 70% of a sweetening agent.
Claim 2
Dependent Claim
63 words
A substantially anhydrous, non-staling chewing gum composition, which comprises: a two component composition, the first being a homogenous premixture of about 10 to about 60% of a chewing gum base and about 2 to about 20% of a polyisobutylene having an average molecular weight of about 20,000 to about 100,000, a second component being about 38% to about 70% of a sweetening agent.
Claim 3
Dependent Claim
31 words
The chewing gum composition of claim 1, wherein the composition contains about 10 to about 40% chewing gum base, about 3 to about 15% polyisobutylene and remainder of a sweetening agent.
Claim 4
Dependent Claim
21 words
The chewing gum composition of claim 1, wherein the chewing gum composition is a sugar or sugarless containing chewing gum composition.
Claim 5
Dependent Claim
27 words
The chewing gum composition of claim 1, wherein the gum base comprises an elastomer selected from the group consisting of natural rubber, synthetic rubber and mixtures thereof.
Claim 6
Dependent Claim
35 words
The chewing gum composition of claim 4, wherein the gum base elastomer is selected from the group consisting of chicle, jelutong, balata, gutta-percha, lechi-capsi, sorva, butadiene-styrene copolymers, polyisobutylene, isobutylene-isoprene copolymers, polyethylene, polyvinylacetate, and mixtures thereof.
Claim 7
Dependent Claim
22 words
The chewing gum composition of claim 1, wherein there is additionally included fillers, coloring agents, flavoring agents, softeners, plasticizers, and mixtures thereof.
Claim 8
Dependent Claim
51 words
The chewing gum composition of claim 6, wherein the flavoring agent is selected from the group consisting of spearmint oil, cinnamon oil, oil of wintergreen (methylsalicylate), peppermint oil, lemon oil, orange oil, grape oil, lime oil, grapefruit oil, apple essence, strawberry essence, cherry essence, pineapple essence, banana oil and mixtures thereof.
Claim 9
Dependent Claim
30 words
The chewing gum composition of claim 1, wherein the sweetening agent is selected from the group consisting of water-soluble sweetening agents, water-soluble artificial sweeteners, dipeptide based sweeteners and mixtures thereof.
Claim 10
Dependent Claim
58 words
The chewing gum compositions of claim 8, wherein the sweetening agent is selected from the group consisting of saccharin acid, saccharin salts, cyclamate salts, acesulfame-K, L-aspartyl-L-phenylalanine methyl ester, xylose, ribose, glucose, mannose, galactose, fructose, dextrose, sucrose, sugar, maltose, partially hydrolyzed starch or corn syrup solids, sorbitol, xylitol, mannitol; talin, dihydrochalcone,; glycyrrhizin; stevia rebaudiana (stevioside); sucralose and mixtures thereof.
Claim 11
Dependent Claim
98 words
A process for preparing a substantially anhydrous, non-staling chewing gum composition, which comprises: preparing a premixture of about 10 to about 60% of a chewing gum base and about 2 to about 20% of a polyisobutylene having an average molecular weight of about 20,000 to about 100,000 by softening the gum base under heat and blending into the gum base the polyisobutylene until a homogenous mixture is obtained; adding about 38% to about 70% of a sweetening agent to the homogenous mixture and mixing until a uniform chewing gum composition is obtained and recovering the chewing gum composition.
Claim 12
Dependent Claim
98 words
A process for preparing a substantially anhydrous, non-staling chewing gum composition, which comprises: preparing a premixture of about 10 to about 60% of a chewing gum base and about 2 to about 20% of a polyisobutylene having an average molecular weight of about 20,000 to about 100,000 by softening the gum base under heat and blending into the gum base the polyisobutylene until a homogenous mixture is obtained; adding about 38% to about 70% of a sweetening agent to the homogenous mixture and mixing until a uniform chewing gum composition is obtained and recovering the chewing gum composition.
Claim 13
Dependent Claim
28 words
The process of claim 10 wherein the chewing gum composition is further cut into chewing gum pieces and wrapped without conditioning, and then recovering the chewing gum composition.
