Abstract
To provide a heat-sealing apparatus capable of achieving an excellent heat-sealing wherein no generation of defective sealing is found even when heat-sealing under severe conditions with a fluid, such as when filling/packing a vegetable juice abundant in water-insoluble vegetable fiber, without providing a ridge on the action face of a high-frequency coil. The high-frequency heat-sealing apparatus consists of a sealing jawprovided with an openable-and-closable high-frequency coiland an opposing jawprovided with a sealing rubberhaving a flat action face, which transversely heat-seals a tubular packing material with a fluid, wherein a grooveinscribed in the end portion on the container's interior side of the sealed zone where both right and left sides are rounded and narrowed, is extended, on the action face of the sealing jaw, over the whole area in the longitudinal direction along the container's interior side of the sealed zone, and a flash portionfor a molten resin is formed adjacent to the outer side on the cutting side of the high-frequency coil. The aforementioned groovemay be a groove wherein its width partially differs.
