PURPOSE:To obtain a container with a label having excellent appearance, durability and peeling resistance by sticking a label on a film base having a plastic inside and a printed layer visible from the outside to the inner surface of a blow-type cavity and conducting a plastic parison into the blow-type mold for blow molding. CONSTITUTION:A label 1 comprises a plastic film base material 12 and a printed layer 3 applied on the outer surface. In the open condition of blow molds 30a, 30b, there is a part to keep a label 1 on the cavity surface 31 of at least one of these two. On this part, a decompressive mechanism 32 is equipped to keep the label 1 on the cavity surface 31 by the suction thereof. Melted plastic parison 34 is extruded from a die 33 and the divided blow molds 30a, 30b are closed and then compressed air is charged in the closed parison 34. The swelled up parison in the mold is held on the surface of the mold for adhesion with the label by the compression. The swelled parison is cooled by contact with the metal mold surface and finally a vessel with a label is completed. |
