The invention relates to a method for applying capsules (1) to a plastic container (54) which is aseptically filled with a liquid and which is weld-sealed with a membrane (80). The capsule (1) to be applied, which preferably is constituted of two aluminum foils (2, 6) having a collar (58), is placed
The invention relates to a method for applying capsules (1) to a plastic container (54) which is aseptically filled with a liquid and which is weld-sealed with a membrane (80). The capsule (1) to be applied, which preferably is constituted of two aluminum foils (2, 6) having a collar (58), is placed on the membrane (80) with a planar surface thereof and the collar is mechanically bent so that it is reliably secured to the container neck (50). The cap (100) is then pressed onto it so that the collar (58) is retained between the container neck (50) and the cap (100) in a form-and in a force-locking connection. The method according to the invention avoids the risk of the capsule being destroyed, which can happen during welding, and the risk of soiling, which can happen during gluing.

1. A method for filling a plastic container (54) with a neck (50), and an attachment of a capsule (1) thereon, in a bottling installation, wherein the capsule (1) is of a plastic deformable material, with substances enclosed therein in a solid, a liquid or a free-flowing condition, which are to be d
1. A method for filling a plastic container (54) with a neck (50), and an attachment of a capsule (1) thereon, in a bottling installation, wherein the capsule (1) is of a plastic deformable material, with substances enclosed therein in a solid, a liquid or a free-flowing condition, which are to be dispensed into the plastic container (54), the method including the steps of first filling the plastic container (54) in an aseptic manner and then sealing the container neck (50) with a membrane (80), whereupon the capsule (1) is attached onto the membrane (80) and a cap or closure (100) is placed over the capsule (1) onto the container neck (50) and wherein the capsule (1) is manufactured of two aluminium films welded to one another, wherein the lower film (2) forms a receiver space (3) which is deep drawn or pressed, and an upper covering aluminium film (6) is planar, so that both films together have a planar edge around the receiver space (3), in a first step, the edge which is formed together by the two films (2, 6) of the capsule (1), is bent out of the planar surface by less than 90° but by more than 45°, so that a peripheral collar arises with a diameter of a magnitude of the container neck (50), onto which the capsule (1) is placed and held on the container neck (50) with a positive fit and/or a friction fit, the cap (100) is stuck on and holds the capsule (1) at least on the container neck (50) in the required position. 2. A method according to claim 1, wherein the edge is bent up, so that a residual edge (7) flush with the planar film (6) remains, which corresponds approximately to a wall thickness of the container neck (50), and the collar delimits the residual edge to an outside. 3. A method according to claim 1, wherein the capsules (1) are punched from the two film layers (2, 6) only up to break off locations (9) and the capsules (1) connected to the film remains (10) get into the bottling installations as sheets (11). 4. A method according to claim 3, wherein the capsules (1) are pressed out of the sheet (11) amid destruction of the break-off bridge locations (9), and the collar is simultaneously formed. 5. A method according to claim 4, wherein formation of the collar (51) is formed by a punch. 6. A method according to claim 1, wherein the collar is formed by flanging. 7. A method according to claim 1, wherein the collar (51) presses the capsule (1) onto the container neck (50). 8. A method according to claim 7, wherein the container (54) with the container neck (50) is led beyond a running pressing strip in a rotating manner. 9. A method according to claim 1, wherein the membrane (80) is formed of a plastic film or an aluminium film coated with plastic, and is welded onto the container neck (50). 10. A method according to claim 9, wherein parts of the membrane (80) which project beyond the edge of the container neck (50) are pressed onto the container neck (50). 11. A method according to claim 9, wherein the membrane is a coated aluminium film which comprises an embossed structure that ensures a controlled tearing of the film. 12. A method according to claim 1, wherein the closure (100) which is positionable over the capsule (1) on the container neck (50), is pressed on or screwed on, and the closure (100) presses the collar (51) onto the container neck (50). 13. A method according to claim 1, wherein the closure (100) is of plastic which is positionable over the capsule (1) onto the container neck (50) and is heated before being placed on. 14. A method according to claim 13, wherein the closure (100) is heated by a warm air blower (110).
