Abstract
A pouched tobacco product includes a lined pouch material of a web and a water-soluble liner adjacent the web and a tobacco component contained within the lined pouch material. The water-soluble liner is interposed between the web and the tobacco component. The liner preferably reduces staining of the web by the tobacco component. Additionally, the liner may include a flavorant.
Claims14
A pouched tobacco product to impart tobacco flavor to the oral cavity, comprising:
- a lined pouch material comprising:
- an outer saliva-permeable water-insoluble web;
- and
- a discrete, separately-formed water-soluble sheet disposed as a liner adjacent said saliva-permeable water-insoluble web;
- and
- a tobacco component contained within said lined pouch material;
- wherein said discrete, separately-formed water-soluble liner sheet is interposed between said saliva-permeable water-insoluble web and said tobacco component, said discrete, separately-formed water-soluble liner sheet thereby reducing the tendency of said tobacco component to impart stain to said outer saliva-permeable water-insoluble web during storage prior to use and retaining freshness of said tobacco component and upon contact with saliva undergoing dissolution so as to allow saliva to reach said tobacco component and to allow said tobacco component to permeate outward through said outer saliva-permeable water-insoluble web.
