Abstract

A fillable closure is used to initiate emptying of a separately fillable capsule moulded into this closure. The capsule is made oxygen-impermeable on the inside or outside with a vapour-deposited layer of silicon dioxide or metal. The volume of the capsule can be reduced through pressurisation from the top, through deformation of its side walls, for cutting or rupturing a sealing foil. The capsule has an asymmetric push button with a pusher surface, a deformable front and side wall and a stable rear wall. The upper end of the rear wall forms a stationary edge, on which the pusher surface can be pivoted downward through deformation of the front and side wall. On the bottom of the pusher surface, a triangle-shaped blade is formed, which ends in a tip, and its triangle edge forming a cutting edge for piercing and cutting the sealing foil on the bottom of the capsule.

Claims

1. A fillable closure with a push-button to initiate emptying of a capsule (2) that is moulded into the closure, wherein the capsule (2) is separately fillable and sealable, and contents of the capsule (2) are emptied into a liquid container which is closed with the closure, characterized in that the capsule (2) is provided on either an inside or an outside, or on both sides thereof with a smooth mirror-finish coating of 60 nm to 80 nm thickness of metal or silicon dioxide, using a plasma assisted physical vapour deposition process;

and after filling, the capsule (2) is sealed with an oxygen-impermeable sealing foil (6); and

that the capsule (2) has a deformable front and side wall, and a volume of the capsule (2) can be reduced through pressurisation on top of the capsule by deformation of the front and side wall of the capsule (2), for cutting open or rupturing the sealing foil (6).

2. The fillable closure according to claim 1, wherein the volume of capsule (2) can be reduced by a downward pressure and concomitant deformation of the front and side wall of the capsule (2);

and the sealing foil (6) is provided with at least one continuous weakening line (25) so that when an internal pressure in the capsule (2) increases, the sealing foil (6) closing the capsule (2) ruptures along the weakening line (25).

3. The fillable closure according to claim 1, wherein the capsule (2) is asymmetric, and has a pusher surface (7), the deformable front and side wall (11), and a stable rigid rear wall (13), and an upper edge of the rear wall forms a stationary edge (10) on which the pusher surface (7) can be pivoted downward through deformation of the front and side wall (11);

and a triangle-shaped blade (8) is formed on a bottom of the pusher surface (7), the triangle-shaped blade (8) ends in a tip (16), and has a triangle edge forming a cutting edge (17) for piercing and cutting the sealing foil (6) on a bottom of the capsule (2).

4. The fillable closure according to claim 3, wherein the rear wall (13) of the capsule (2) is connected with an inner wall (14) of the closure through a bar (12) such that the rear wall (13) is not deformable.

5. The fillable closure according to claim 3, wherein a punch (9) is formed on both sides of the triangle-shaped blade (8) at the bottom of the pusher surface (7) for pressing down two halves of cut sealing foil (6) and thereby ensuring the capsule (2) is emptied completely.

6. The fillable closure according to claim 5, wherein the punch (9) extends downwards lesser than the tip (16) of the triangle-shaped blade (8).

7. The fillable closure according to claim 3, wherein a reinforcing wall (5) is formed on a front end of the triangle-shaped blade (8), connecting along a curved line (26) to the pusher surface (7), for ensuring the triangle-shaped blade not bending laterally when the pusher surface is pressed down.

8. The fillable closure according to claim 1, wherein the capsule (2) is asymmetrically shaped, and has a pusher surface (7), the deformable front and side wall (11), and a stable rear wall (13), and an upper edge of the rear wall forms a stationary edge (10) on which the pusher surface (7) can be pivoted downward through deformation of the front and side wall (11);

and on an underside of the pusher surface (7) a wedge (30) is formed, the wedge forms a cutting edge (17) and ends in a tip (16), for piercing and cutting the sealing foil (6) at a bottom of the capsule (2).

9. The fillable closure according to claim 8, wherein the rear wall (13) of the capsule (2) is connected with an inner wall (14) of the closure through a bar (12) such that the rear wall (13) is not deformable.

10. The fillable closure according to claim 1, wherein the capsule (2) has an asymmetric shape, and has a pusher surface (7), the deformable front and side wall (11), and a stable rear wall (13);

the rear wall forms a stationary edge (10) at a top thereof, and the pusher surface (7) can be pivoted on the stationary edge (10) downward through deformation of the front and side wall (11); and

wherein the pusher surface has a recess (29) that forms a punch (27) protruding downward, for pushing open the sealing foil (6) on a bottom of the capsule (2).

11. The fillable closure according to claim 10, wherein the rear wall (13) of the capsule (2) is connected with an inner wall (14) of the closure through a bar (12) such that the rear wall (13) is not deformable.

12. The fillable closure according to claim 1, wherein the capsule (2) has a pusher surface (7), the deformable front and side wall (11), and an edge (10) arranged on one side of the closure, above a lower edge of the deformable front and side wall (11) in such a way that the edge (10) forms a pivot hinge on the one side of the closure, and on a diametrically opposite side of the edge (10), the front wall is foldable in a section lower than the edge (10).

13. The fillable closure according to claim 1, wherein the closure comprises a lid (18) formed on a hinge (19) on an edge of the closure to provide a tamper-proof seal, and a latch (20) is moulded to an opposite side of the hinge (19) as a snap fit element;

when the lid (18) is closed, the latch (20) engages with a window (22) formed in a strip (21) on an edge of the closure.

14. The fillable closure according to claim 1, wherein the sealing foil comprises one or a plurality of continuous, non-intersecting weakening lines (25) in a form of fillets.
