The present invention provides a method of manufacturing liquid-filled capsules for use in smoking articles. The method comprises the steps of: providing a capsule shell (101) defining a cavity (106) and having an open end (105)； dispensing a volume of liquid (L) into the cavity (106) through the open end (105) of the shell (101), whereby a clearance (δ) is left between an upper surface of the liquid (L) dispensed into the cavity (106) and the open end (105) of the shell (101)； and sealing the open end (105) of the shell (101) with a portion of sheet material to provide a liquid-filled capsule (100) containing the volume of liquid (L). The present invention also provides an apparatus for manufacturing liquid-filled capsules for use in smoking articles. The apparatus comprises: a holder for holding one or more capsule shells (101)； a conveyor for moving or transporting the holder with the one or more capsule shells (101)； a filling station (3) for dispensing a liquid into a cavity (106) of each of the capsule shells (101) held by the holder, wherein the filling station (3) is configured to provide a pre-defined clearance (δ) between the liquid dispensed into the cavity (106) and the open end (105) of each shell (101)； and a sealing station (4) for covering and sealing an open end (105) of each capsule shell (101) with a sheet material to form a capsule (100). The invention further provides a liquid-filled capsule (100) for use in smoking articles, wherein the capsule comprises: a capsule shell (101) defining a cavity (106) and having an end (105) providing a filling opening； a volume of liquid (L) contained within the cavity (106)； and a cap (102) which covers and seals the end (105). A pre-defined clearance (δ) is provided between an upper surface of the liquid (L) contained in the cavity (106) and the end (105) of the shell (101).本發明提供一種用於菸品之充液膠囊的製造方法。該方法包括下列各步驟：提供一膠囊殼體(101)，該殼體界定出一空穴(106)並設有一開口端(105)；經由殼體(101)的開口端(105)將一定數量的液體(L)配送到空穴(106)內，藉以在配送到空穴(106)之液體(L)的上表面
