First Claim
Patent Images
1. A chewing gum which comprises:
- a gum base;
a water soluble bulk portion; and
,a gradual release structure formed by melt spinning a mixture of active agent and spinnable polymeric wall material, having more than zero but less than about 55 percent by weight active agent, into a fiber, and cutting the fiber.

22. A process for making a chewing gum having a gradual release structure which comprises the steps of:
-
preparing a gum base; preparing a water soluble bulk portion; preparing a mixture of Aspartame and wall material, having from about 10 percent by weight to about 25 percent by weight Aspartame; melt spinning the mixture to form a fiber; stretching the fiber; cutting the fiber; and combining the gum base, water soluble bulk portion and gradual release structure. - View Dependent Claims (23, 24, 25, 26, 27)
