Claims13
A closure for pharmaceutical packages, comprising:
- a cap made of a dielectric material and attachable on a vial;
- a metal foil which in its assembled state rests on a rim of said vial, wherein at least on a surface that rests on the rim the metal foil is provided with an adhesive which is meltable inductively through the metal foil;
- and
- an elastic seal inserted above the metal foil;
- wherein the cap has a base wall with at least one opening through which the elastic seal and the metal foil can be perforated;
- wherein the elastic seal is adapted so that once the cap has been applied on the vial the metal foil is already sealingly pressed onto the rim of the vial without the adhesive having been melted yet;
- and
- wherein the closure is a snap-on closure.

A method for sealing a vial with a closure for pharmaceutical packages which comprises
- a cap made of a dielectric material and attachable on a vial;
- a metal foil which in its assembled state rests on a rim of said vial, wherein at least on a surface that rests on the rim the metal foil is provided with an adhesive which is meltable inductively through the metal foil;
- and
- an elastic seal inserted above the metal foil;
- wherein the cap has a base wall with at least one opening through which the elastic seal and the metal foil can be perforated;
- and
- wherein the method comprises the steps of:
- filling the vial;
- then applying the closure in an aseptic area, wherein the vial is already sealed when the closure is applied;
- and
- subsequently heating the metal foil by induction so that the adhesive melts thereby creating a material bond between the metal foil and a rim of the vial, wherein the inductive heating of the metal foil is performed after leaving the aseptic area.
