Claims (8)

In order to heat-seal the heat-welding sheet, a heat-sealing device provided with a heating element that generates heat when energized in the heater base, the heater base has a trident seal portion extending in three directions, A heat-sealing device, wherein the heat generating body is reversed so as to extend in three directions of the heater base and pass through the three-pronged seal portion, and both ends of the heat generating body are connected to a power source. The heat sealing apparatus according to claim 1, wherein the heating element constitutes a sheet heating surface of a heater base. In order to perform heat sealing in a substantially T shape on a long heat-weldable sheet, a heat-sealing device provided with a heating element that generates heat by energizing a heater base, wherein the heating element is the thermal welding A first horizontal portion and a second horizontal portion extending in the longitudinal direction of the adhesive sheet, and a substantially U-shaped U-shaped portion extending in the width direction of the heat-weldable sheet, and one end portion of the first horizontal portion; One end of the U-shaped part is connected, and one end of the second horizontal part and the other end of the U-shaped part are connected, and the other end of the first horizontal part and the second horizontal part. The heat seal apparatus characterized by the other end part of being connected to the power supply. The heat sealing apparatus according to claim 3 , wherein the heating element constitutes a sheet heating surface of a heater base. The U-shaped portion has a pair of vertical portions and a reversing portion, and a heat radiating portion that radiates heat of the heating element in a region where the heat-weldable sheet does not contact when heat sealing is performed on the reversing portion. The heat sealing apparatus according to claim 4 provided. Each of the end portions of the first horizontal portion and the U-shaped portion and the end portions of the second horizontal portion and the U-shaped portion have a predetermined radial width having an outer diameter side edge and an inner diameter side edge. Any one of claims 3 to 5, wherein the outer diameter side edges of the respective bending parts are displaced to the inner diameter side with respect to a virtual arc drawn around the bending center of the inner diameter side edge. The heat sealing apparatus according to 1 . Each of the end portions of the first horizontal portion and the U-shaped portion and the end portions of the second horizontal portion and the U-shaped portion have a predetermined radial width having an outer diameter side edge and an inner diameter side edge. The radial width of the curved portion on the first horizontal portion side is narrower than the width of the first horizontal portion, and the radial width of the curved portion on the second horizontal portion side is the first horizontal portion. The heat seal device according to any one of claims 3 to 5, wherein the heat seal device is narrower than the width of the two horizontal portions . The heat sealing apparatus according to any one of claims 1 to 7 , a medicine distribution apparatus that distributes and discharges medicines by a predetermined amount, and a package in which the medicine discharged from the medicine distribution apparatus is formed by the heat welding sheet.
