Claims

[Scope of utility model registration request]

A heat-sealing device for heat-sealing a sealing film around the opening of a cup-shaped container, the inner sealing plate being movable up and down, each having a ring-shaped pressing part having a widthwise central part protruding forward at its tip. and an outer sealing plate which is arranged around the inner sealing plate and is movable up and down, and the sealing film is pressed into the cup-shaped container by the pressing portions of the inner sealing plate and the outer sealing plate, which are heated to a predetermined temperature. When the sealing film is heat-sealed to the container by pressing against the periphery of the opening of the container, the pressing part of the inner sealing disc is configured to press the sealing film with a stronger pressing force than the pressing part of the outer sealing disc. A heat sealing device featuring:
