In the case of a hot-water reservoir with an insulating layer 8 foamed in between a receptacle (tank) 1 and a jacket (outer casing) 2, it is intended to be able to manufacture with little waste a foam element 9, which prevents the escape of insulating foam during the foaming. The foam element 9 consists of a slotted, rectangular cut-to-size piece 12. The slot 13 forms two longitudinal parts 14 and 15 which, when spread apart, lie around the flange 4. <IMAGE>
