Abstract
A method and apparatus is proposed for sealing hard gelatine capsules or similar hollow containers filled with liquid, so that a secure sealing of the fill opening is attained with the aid of a sealant and in which an escape of the sealant--as a result of which the fill opening would be sealed either incorrectly or not at all--is avoided.
Claims3
A method for filling and sealing hard gelatine capsules or the like having a dome-shaped end wall comprising the steps of, forming a spherical depression in said capsule end wall, inserting a hollow needle through said capsule end wall centrally of said spherical depression to form a fill opening, introducing a medicant into the interior of said capsule through said hollow needle, and filling said spherical depression with a sealing mass to seal said fill opening and conform said end wall containing said spherical depression to substantially its original shape.
