A refrigeration appliance, in particular a domestic refrigerator, comprising - an inner case which forms a refrigeration compartment, - an outer case which encloses a rear surface of the inner case, - one or more than one air escape opening (4, 4a, 4b) for allowing air to escape to an outside during a curing process of foam material which is to be filled into an intermediate region between the inner case and the outer case, wherein the air escape opening (4, 4a, 4b) is formed into the outer case, - one or more than one guiding means for movably arranging one or more than one sealing element (1, 1a, 1b) into the intermediate region respectively and - one or more than one corresponding sealing element (1, 1a, 1b), characterized in that - the sealing element comprises an air impermeable resilient body which has a sealing skirt (7a, 7b) and a counterpart guiding means (12a, 12b) for cooperating with the corresponding guiding means of the refrigeration appliance, - the body is movably mountable into the intermediate region via its counterpart guiding means (12a 12b) so as to float upwards from a first position up to a second position under the pushing action of the curing foam material during a curing process, - at the first position an air gap which fluidly connects the intermediate region with the corresponding air escape opening (4, 4a, 4b) is left above the sealing skirt (7a, 7b) of the body, - at the second position the sealing skirt (7a, 7b) is pushed to cover the corresponding air escape opening (4, 4a, 4b) so as to leak-tightly seal the intermediate region from the outside against leakage of curing foam material, - the outer case has a flat surface in the vicinity of each air escape opening (4, 4a, 4b), - the sealing skirt (7a, 7b) comprises a suction cup (17a, 17b) which touches at the second position the corresponding flat surface. - an inner case which forms a refrigeration compartment, - an outer case which encloses a rear surface of the inner case, - one or more than one air escape opening (4, 4a, 4b) for allowing air to escape to an outside during a curing process of foam material which is to be filled into an intermediate region between the inner case and the outer case, wherein the air escape opening (4, 4a, 4b) is formed into the outer case, - one or more than one guiding means for movably arranging one or more than one sealing element (1, 1a, 1b) into the intermediate region respectively and - one or more than one corresponding sealing element (1, 1a, 1b), characterized in that - the sealing element comprises an air impermeable resilient body which has a sealing skirt (7a, 7b) and a counterpart guiding means (12a, 12b) for cooperating with the corresponding guiding means of the refrigeration appliance, - the body is movably mountable into the intermediate region via its counterpart guiding means (12a 12b) so as to float upwards from a first position up to a second position under the pushing action of the curing foam material during a curing process, - at the first position an air gap which fluidly connects the intermediate region with the corresponding air escape opening (4, 4a, 4b) is left above the sealing skirt (7a, 7b) of the body, - at the second position the sealing skirt (7a, 7b) is pushed to cover the corresponding air escape opening (4, 4a, 4b) so as to leak-tightly seal the intermediate region from the outside against leakage of curing foam material, - the outer case has a flat surface in the vicinity of each air escape opening (4, 4a, 4b), - the sealing skirt (7a, 7b) comprises a suction cup (17a, 17b) which touches at the second position the corresponding flat surface.
