PURPOSE:To make a container not bulky, by a method wherein connectedly molded main bodies of bases are fitted in cavities defined by a fixed metallic mold and a movable metallic mold, and then a soft synthetic resin stamp member is molded on each of the main bodies while a portion of the resin is charged into slip-off preventing parts. CONSTITUTION:The first fixed metallic mold 8 and the first movable metallic mold 11 are set to form the cavities for the main bodies 3 of the bases. A hard synthetic resin is injected into a resin-introducing part 14 as indicated by an arrow (a), whereby it is charged under pressure into each cavity through each runner 14a. Then, each of the main bodies 3 is placed in each recessed part 17 of the second fixed metallic mold 16, and the second movable metallic mold 18 is set onto the mold 16, whereby the cavities 20 for stamp members 4 are formed. Then, a soft synthetic resin is injected into a resin-introducing part 21 as indicated by an arrow (b) by an injection molding machine, whereby it is charged under pressure into each of the cavities 20 through each runner 21a. |
