The invention relates to a cigarette butt receiving bag of disposable type for receiving and extinguishing glowing cigarettes, which bag (1) comprises a forward sheet (2), a rearward sheet (4), which sheets are sealed to each other along their outer edges (6) leaving an edge portion unsealed so as to provide an opening (8) for receiving a cigarette butt (10), thereby forming a cigarette butt receiving compartment (12) between said forward and rearward sheets (2, 4), and comprising a fluid (14), which is disposed in two heat insulating volumes (16, 18) within the cigarette butt receiving compartment (12). A first heat insulating volume (16) is delimited by the forward sheet (2) and a forward inner layer material (20) which is sealed against the forward sheet (2). A second heat insulating volume (18) is delimited by the rearward sheet (4) and a rearward inner layer material (22) which is sealed against the rearward sheet (4). The invention also relates to a method of manufacturing a cigarette butt receiving bag of disposable type.
