ABSTRACT:
A material supply device in a stowing and packaging machine wherein a supplied film or sheet (S) is continuously introduced around a vertically placed guide tube (1) and sealed along the length thereof by a sealer (14), and the contents are stowed between upper and lower seals while the film or sheet is sealed across the width thereof at spaced positions by a sealing device (17) to form a packaging member (S'). The contents consists of a liquid material and powder or granular solid material with hygroscopicity and solubility in the liquid body. A liquid supply tube (3) supplying the liquid into the packaging member (S"), and a solid material supply tube (2) supplying the solid material are disposed in the guide tube (1), and have lower ends (18, 19) located below the lowermost end of the guide tube (1), and above the packaging section. A blast pipe (4) supplies a dry gaseous material to prevent the solid body material from getting wet and is disposed internally of the solid body supply tube (2,20).
