Patent number: 4238475Abstract: A chewing gum is provided which is capable of releasing into the oral cavity relatively large amounts of finely-divided water-insoluble therapeutic materials, which chewing gum includes a water-soluble phase formed of aqueous softener, and the finely divided therapeutic component to be released, said therapeutic component being coated with a water-soluble coating agent for preventing resorption of therapeutic component back into the gum base and, optionally, a first sweetener, dispersed throughout the aqueous softener, and a relatively water-insoluble phase formed of a plurality of separate and distinct masses suspended in and dispersed throughout the water-soluble phase, each of said masses formed of particles of gum base and, optionally, particles of a second sweetener, suchas mannitol and/or sorbitol or sugar, enveloped by particles of gum base. Upon chewing the above gum, the therapeutic component is, in fact, released in the oral cavity in relatively large quantities, together with the aqueous softener.Type: GrantFiled: August 1, 1979Date of Patent: December 9, 1980Assignee: Life Savers Inc.Inventors: Frank Witzel, Wayne J.

Patent number: 4065579Abstract: A chewing gum is provided which includes a coated chalk-containing base and contains a poorly water-soluble sweetening agent, such as the free acid form of saccharin, and/or food acid, the sweetening agent and/or food acid being coated with an edible coating agent. The coating agent inhibits reaction of the free acid or food acid with chalk (CaCO.sub.3) and thus inhibits formation of soluble salts which are quickly solubilized in the mouth.Type: GrantFiled: October 12, 1976Date of Patent: December 27, 1977Assignee: Life Savers, Inc.Inventors: Donald A. M. Mackay, Daniel Schoenholz
