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.本公開涉及一種用於生產、填充和密封藥劑容器(2')的方法,所述方法包括吹製-填充-密封製程,所述吹製-填充-密封製程包括:- 模製步驟,在模製步驟中,型坯(2)在模具(1)內膨脹,形成藥劑容器(2'),- 填充步驟,在填充步驟中,藥劑(M)被填充到藥劑容器(2')中,- 密封步驟,在密封步驟中,密封所述藥劑容器(2')的頸部(2.2')的遠端,- 其中,模具(1)的尺寸被確定為使得頸部(2.2')形成有足夠小的內半徑(r),允許對藥劑(M)形成毛細效應,使得在填充步驟和密封步驟之後保留在頸部(2.2')中的氣泡藉由毛細力固定在頸部(2.2')內。本公開還涉及藉由所述方法生產的藥劑容器(2')。
