Abstract
Official abstract text for this publication.
Provided herein are pouched products including a chromogenic material or an electronic component, wherein the chromogenic material and the electronic component are responsive to a stimulus. The stimulus may be a change in pH, a change in temperature, or exposure to moisture. Such pouched products can be employed to detect various changes associated with the pouched product.
First claim
Opening claim text (preview).
What is claimed is: 1 . A pouched product configured for oral use, comprising a porous pouch material which is a nonwoven fleece material comprising a chromogenic material which is a moisture-sensitive indicator, and further comprising a composition enclosed within the porous pouch material, the composition comprising: a particulate cellulose-based filler in an amount of at least 30% by weight, based on the total weight of the composition; and one or more flavorants, active ingredients, or both. 2 . The pouched product of claim 1 , wherein the chromogenic material is adsorbed in the porous pouch material. 3 . The pouched product of claim 1 , wherein the chromogenic material is embedded in the porous pouch material. 4 . The pouched product of claim 1 , wherein the chromogenic material is printed on the porous pouch material. 5 . The pouched product of claim 1 , wherein the chromogenic material is covalently bound to the porous pouch material. 6 . A pouched product configured for oral use, comprising a porous pouch material which is a nonwoven fleece material comprising a thermochromic material, and further comprising a composition enclosed within the porous pouch material, the composition comprising: a particulate cellulose-based filler in an amount of at least 30% by weight, based on the total weight of the composition; and one or more flavorants, active ingredients, or both. 7 . The pouched product of claim 6 , wherein the thermochromic material is a liquid crystal. 8 . The pouched product of claim 6 , wherein the thermochromic material is a leuco dye. 9 . The pouched product of claim 6 , wherein the thermochromic material is adsorbed in the porous pouch material. 10 . The pouched product of claim 6 , wherein the thermochromic material is embedded in the porous pouch material. 11 . The pouched product of claim 6 , wherein the thermochromic material is printed on the porous pouch material. 12 . The pouched product of claim 6 , wherein the thermochromic material is covalently bound to the porous pouch material.
