Abstract

The document relates to a method of making a disposable double walled structure comprising an inner wall portion (51) surrounding a product space presenting a cross section and extending along an axial direction, perpendicular to the cross section, between first and second axially spaced apart portions, and an outer wall portion (52) at least partially surrounding the inner wall portion (51), wherein an insulating space is formed between the inner and outer wall portions. The method comprises forming the inner and outer walls (51, 52) in one piece, such that the inner and outer walls are connected at the first axial portion and at least partially overlap as seen in a direction perpendicular to the axial direction, and bending at least one of the inner (51) and outer (52) wall portions in the direction perpendicular to the axial direction towards the other one of the inner (51) and outer (52) wall portions at the second axial portion, so as to form the insulating space.
