<p><P>PROBLEM TO BE SOLVED: To provide a heat sealing apparatus which can form a protrusion such as a braille on a seal area of a sealed object while preventing a decrease in sealability, a removable member, and the sealed object. <P>SOLUTION: An adhesive sheet 54 detachably arranged to at least one of a first pressing part 4 and a second pressing part 5, is formed with a plurality of small holes 54a. When the sealed object is pressed and held between the first pressing part 4 and the second pressing part 5 and is heated and melted, the heated and melted sealed object enters into the plurality of small holes 54a formed on the adhesive sheet 54 and a plurality of protrusions in shapes corresponding to the plurality of small holes 54a are formed on the seal ares at the same time when sealing takes place. Since there is no protrusion at the pressing parts 4, 5 unlike a structure where a melting operation is performed with a sealed object put between a protrusion and a dent, interference of the protrusion at an edge of the dent owing to positional accuracy does not occur. Therefore, a decrease in sealability by holes formed on the sealed object or the like can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
