Abstract
Abstract A coextruded chewing gum is provided which includes an extruded center portion surrounded by and bonded to an extruded outer shell portion. The center portion of the coextruded chewing gum will be of a generally soft consistency, substantially softer than that ordinarily employed in chewing gums of conventional structure, while the outer shell portion will provide a protective layer or coating for the core portion to inhibit sweating and stickiness and thereby allow for use of conventional wrapping machines.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
151 words
A coextruded chewing gum having a soft gum center portion, comprising an extruded soft gum core portion and an outer shell portion formed of chewing gum and extruded simultaneously with said core portion, said core portion formed of chewing gum containing more than about 5 up to about 10% by weight moisture based on the weight of the core portion and containing therein a preformed recrystallized sweetener combination including at least two sweeteners which have been recrystallized as a mixture, dispersed as said recrystallized mixture in said gum base, and one or more flavors dispersed in said gum base, said outer shell portion, which contains any of gum base, bulking agents, sweeteners, and flavors and has a harder consistency than said core portion, being bonded to said core portion to provide a support and protective barrier therefor to retain said moisture in said core portion and retard migration of moisture therefrom.
Claim 2
Dependent Claim
151 words
A coextruded chewing gum having a soft gum center portion, comprising an extruded soft gum core portion and an outer shell portion formed of chewing gum and extruded simultaneously with said core portion, said core portion formed of chewing gum containing more than about 5 up to about 10% by weight moisture based on the weight of the core portion and containing therein a preformed recrystallized sweetener combination including at least two sweeteners which have been recrystallized as a mixture, dispersed as said recrystallized mixture in said gum base, and one or more flavors dispersed in said gum base, said outer shell portion, which contains any of gum base, bulking agents, sweeteners, and flavors and has a harder consistency than said core portion, being bonded to said core portion to provide a support and protective barrier therefor to retain said moisture in said core portion and retard migration of moisture therefrom.
