    • A portable electric wallpaper steamer has a generator (G) including a base (1) and lid (2), both injection molded of plastic material. An elastomeric sealing ring (29) is seated in a recess in a circumferential interengagement zone between the lid and base and is held compressed by the interengagement of engagement members (24) on the lid with cooperating engagement members (39) on the base. The lid-engagement members (24) and base-engagement members (39) comprise integrally molded parts of the lid and base and one or both are resiliently deformable so that they can be brought into snap-fit engagement with each other by downward movement of the lid relative to the base to form a steam pressure tight seal. An electric heating element (6) is mounted in the base for heating water therein to generate steam. The lid includes a handle (9), filling port (10), safety valve (13) and a steam outlet port (21) connected to a wall paper steaming plate (W) by a pipe.
