The present disclosure relates to a method for producing, filling and sealing a medicament container (2′), the method comprising a blow-fill seal process comprising: a molding step, in which a parison (2) is inflated within a mold (1) to form the medicament container (2′), a filling step, in which a medicament (M) is filled into the medicament container (2′), and a sealing step, in which a distal end of a neck (2.2′) of the medicament container (2′) is sealed, wherein the mold (1) is dimensioned such that the neck (2.2′) is formed with an internal radius small enough to allow for a capillary effect of the medicament (M) so that an air bubble remaining in the neck (2.2′) after the filling step and the sealing step is fixed within the neck (2.2′) by capillary forces. The present disclosure also relates to a medicament container (2′) produced by said method.
