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.

A steam generator for generating steam at a pressure greater than ambient atmospheric pressure, comprising: a moulded plastic base (1) including a sidewall (36); a moulded plastic lid (2); the lid (2) and the base (1) defining between them a circumferential inter-engagement zone; the lid (2) having at the inter-engagement zone at least one engagement member (24) with an engagement face (38) directed generally away form the base (1), when assembled thereto; the base (1) having at the inter-engagement zone at least one engagement member (39) with an engagement face (40) directed generally away from the lid (2), when assembled thereto; an electrical heating element (4) mounted in the base (1); and an elastomeric sealing ring (29) arranged on assembly, around the circumferential inter-engagement zone, between the base (1) and the lid (2); the lid-engagement and base engagement members (24, 39) engaging via their engagement faces (38, 40) with resilient deformation of either or both of the lid-engagement and base-engagement members (24, 39) on assembly of the lid (2) to the base (1) so as to compress the sealing ring (29) for sealing contact with both the base (1) and the lid (2), for containing steam in the generator at a pressure greater than an ambient atmospheric pressure; and means (P, W) for providing the steam from the generator at the pressure greater than the ambient atmospheric pressure.
