A pouched product for oral use comprising a liquid permeable cover material and a filling material

Abstract

A pouched product ( 1 ) for oral use comprising a liquid permeable cover material ( 2 ) enclosing a filling material ( 3 ), the filling material comprising a particulate material consisting of water insoluble particles and one or more water-soluble components in addition to the particulate material. The particles ( 4 ) of the particulate material have a particle density and a bulk density, the particle density being in the range of from 0.9 g/cm3 to 2.0 g/cm3 and being at least 1.4 times greater than the bulk density of the particulate material. The filling material has a pre-use moisture content of from 1% by weight of the filling material to 35% by weight of the filling material ( 3 ) and is free from tobacco material or comprises tobacco material in an amount within the range of from 0.05 wt % to 10 wt % based on the total weight of the filling material.

1 . A pouched product for oral use comprising a liquid permeable cover material and a filling material comprising a particulate material consisting of water insoluble particles, and one or more water-soluble components in addition to the particulate material, the filling material being enclosed by the liquid permeable cover material, the particles of the particulate material having a particle density and a bulk density, characterized in that the particles of the particulate material have a particle density in the range of from 0.9 g/cm 3  to 2.0 g/cm 3 , the particle density being at least 1.4 times greater than the bulk density of the particulate material, the filling material having a pre-use moisture content of from 1% by weight of the filling material to 35% by weight of the filling material, and the filling material being free from tobacco material or the filling material comprises tobacco material in an amount within the range of from 0.05 wt % to 10 wt % based on the total weight of the filling material. 
     
     
         2 . A pouched product according to  claim 1 , wherein the particle density is 1.4 to 5 times greater than the bulk density of the particulate material. 
     
     
         3 . A pouched product according to  claim 1 , wherein the particles of the particulate material comprises water insoluble hydrophilic particles. 
     
     
         4 . A pouched product according to  claim 1 , wherein the particles of the particulate material constitute 75% by dry weight to 99% by dry weight of the filling material. 
     
     
         5 . A pouched product according to  claim 1 , wherein the particles of the particulate material have an average particle size within the range of from 0.3 mm to 3.0 mm. 
     
     
         6 . A pouched product according to  claim 1 , wherein the particulate material contains less than 0.5% of particles which are small enough to pass through a sieve having a mesh size of 250 μm. 
     
     
         7 . A pouched product according to  claim 1 , wherein the filling material comprises nicotine, the nicotine being added in the filling material in the form of a nicotine compound. 
     
     
         8 . A pouched product according to  claim 1 , wherein the filling material comprises an additive selected from the group consisting of a flavouring agent, a sweetener, a humectant, and any mixture thereof. 
     
     
         9 . A pouched product according to  claim 10 , wherein the additive comprises a flavouring agent. 
     
     
         10 . A pouched product according to  claim 1 , wherein at least one of the one or more water-soluble components is present on a surface of at least some of the particles of the particulate material. 
     
     
         11 . A pouched product according to  claim 1 , wherein at least one of the one or more water-soluble components is present in interstices between the particles of the particulate material. 
     
     
         12 . A pouched product according to  claim 1 , wherein the liquid permeable cover material is a nonwoven material.
