Filling element used for flavor inhalation article and method for manufacturing filling element

Abstract

Provided is a filling element used for a flavor inhalation article, the filling element including: a sheet fill section obtained by randomly gathering and reducing the diameter of one sheet in a width direction that intersects the longitudinal direction of the sheet; and, a roll paper wrapped around the sheet fill section. The sheet is a dry nonwoven fabric obtained by bonding plant-derived fibers together with a binder and drying the fibers.

1 . A filling element used for a flavor inhaling article, the filling element comprising:
 a sheet filled part reduced in diameter by randomly gathering a sheet in a width direction intersecting with a longitudinal direction of the sheet; and   a wrapping paper wrapping the sheet filled part, wherein   the sheet is a dry nonwoven fabric obtained by bonding plant-derived fibers to each other with a binder and drying the plant-derived fibers.   
     
     
         2 . The filling element according to  claim 1 , wherein
 the filling element has a diameter of 5.2 mm to 8.2 mm, and   the sheet has a basis weight of 30 g/m 2  to 100 g/m 2 , a thickness of 0.7 mm to 2.0 mm, and a sheet width in the width direction of 40 mm to 350 mm.   
     
     
         3 . The filling element according to  claim 1 , wherein the sheet has crimped parts arranged in the width direction and extending in the longitudinal direction. 
     
     
         4 . The filling element according to  claim 3 , wherein a crimped depth of each crimped part is less than or equal to 1.2 mm. 
     
     
         5 . A manufacturing method for a filling element used for a flavor inhaling article, the manufacturing method comprising:
 a sheet processing step of processing a serial sheet made of a dry nonwoven fabric obtained by bonding plant-derived fibers to each other with a binder and drying the plant-derived fibers, while conveying the serial sheet;   a gathering step of forming a gathering rod reduced in diameter by gathering the sheet, processed in the sheet processing step, in a width direction intersecting with a longitudinal direction of the sheet in a course of conveying the sheet;   a wrapping step of wrapping the gathering rod, formed in the gathering step, with a wrapping paper to form a filler rod; and   a cutting step of cutting the filler rod, formed in the wrapping step, into the filling element.   
     
     
         6 . The manufacturing method for a filling element according to  claim 5 , wherein, in the sheet processing step, a crimping process of forming crimped parts, arranged in the width direction and extending in the longitudinal direction, in the sheet is performed in a course of conveying the sheet. 
     
     
         7 . The manufacturing method for a filling element according to  claim 6 , further comprising
 a sheet feeding step of, before the sheet processing step, feeding the serial sheet to a conveying path, wherein   in the sheet feeding step, an S-feed process of spanning the sheet unreeled from a bobbin in an S-shape between a pair of rollers spaced apart up and down and feeding the sheet to the conveying path is performed.
