PURPOSE:To enable user to form a vessel simply and also enable several kinds of vessels to be formed in one machine by forming a case manufacturing mechanism into a cassette that is capable of being selectively mounted on the forming machine. CONSTITUTION:An expansion plate A is prepared beforehand and a cassette 2 corresponding to the expansion plate A is mounted on the cassette mounting part 12 of a main body 1 and then electrification to a heating plate 22 is made into a possible state. When a packing vessel B is formed, the heating plate 22 is heated and the expansion plate A is inserted into the upside of the cassette 2, at the same time, fitted to a positioning wall plate 23, and when a cylinder 11 is actuated and the expansion plate A is pressed into a hole defined by inclined wall surfaces 21, each side plate (a) of the expansion plate A rises, simultaneously, the end periphery (b) of each side plate (a) comes into contact with the heating plate 22 and thus melted, so that they are welded each other for forming a vessel B. |
