Fillable closure device with triggering pushbutton
View Patent ↗The fillable closure with a triggering pushbutton comprises a filler neck ( 3 ) that is to be screwed onto or joined to a container neck ( 4 ) as well as a closure cap ( 1 ) which is associated to the filler neck ( 3 ) and can be joined, pivoted and snapped-on the filler neck ( 3 ) by means of a hinge connection. A separately fillable container ( 2 ) can be inserted into the filler neck ( 3 ), the container being closed at the bottom with a sealing foil ( 19 ) that can be pierced or cut open. The closure cap ( 1 ) comprises a cap cover as a pusher disc ( 7 ), which can be pressed downward in the axial direction while deforming. By pressing the cap cover downward on the container ( 2 ) inserted in the filler neck or on a rigid opening element accommodated therein, the opening element can be pressed downward so that the sealing foil ( 19 ) of the container ( 2 ) can be pierced and cut open.
1. A fillable closure device with a triggering pushbutton, comprising:
(a) a connector ( 3 ) to be placed on a container neck ( 4 ), said connector ( 3 ) comprising a smooth sleeve ( 31 ) at a lower portion thereof, fitting into an interior of the container neck 4 , and a collecting grid ( 32 ) integrally formed at a bottom of the smooth sleeve ( 31 ) underneath an interior of the smooth sleeve;
(b) a separate container ( 2 ) inserted into the connector ( 3 ) and positioned above the collecting grid ( 32 ), the separate container ( 2 ) having a closed deformable top, an open bottom sealed by a sealing foil ( 6 ) that can be pierced or cut open, and a separate stiff piercing and cutting element ( 8 ) disposed inside the separate container above the sealing foil ( 6 ); and
(c) a cap ( 1 ) removably attached to an upper portion of the connector ( 3 ), the cap ( 1 ) comprising a deformable cap cover ( 30 ) able to be pressed downward in an axial direction, the cap cover situated above the separate container ( 2 ), wherein when the cap cover is pressed downward onto the deformable top of the separate container ( 2 ), the stiff piercing and cutting element ( 8 ) inside the separate container ( 2 ) is pressed downward against the sealing foil ( 6 ), thereby causing the sealing foil ( 6 ) to be pierced and cut open.
2. The fillable closure device with triggering pushbutton according to claim 1 , wherein the collecting grid ( 32 ) collects the separate piercing and cutting element ( 8 ) dropped from the separate container, when the sealing foil ( 6 ) is cut open.
3. The fillable closure device with triggering pushbutton according to claim 1 , wherein the collecting grid ( 32 ) has a star-shaped structure.
4. The fillable closure device with triggering pushbutton according to claim 1 , wherein the deformable top of the separate container ( 2 ) bulges upwardly in the manner of a dome.
5. The fillable closure device with triggering pushbutton according to claim 1 , wherein the stiff piercing and cutting element ( 8 ) has a ring with downwardly directed piercing and cutting teeth and a pressing stem ( 37 ) extending upward from the ring.
6. The fillable closure device with triggering pushbutton according to claim 5 , wherein the pressing stem ( 37 ) is connected in a star-shaped manner to the ring.
7. The fillable closure device with triggering pushbutton according to claim 1 , wherein the separate container ( 2 ) is snapped or clamped into place.
8. The fillable closure device with triggering pushbutton according to claim 1 , wherein the deformable cap cover ( 30 ) of cap ( 1 ) is in a form of upward dome.
9. The fillable closure device with triggering pushbutton according to claim 1 , wherein the cap ( 1 ) has a downwardly extended connector ( 11 ) that is slid into the smooth sleeve ( 31 ) of the connector ( 3 ), and the separate container ( 2 ) is inserted into an interior of the downwardly extended connector ( 11 ).
10. The fillable closure device with triggering pushbutton according to claim 1 , wherein the connector ( 3 ) is in a form of threaded sleeve placed on container neck 4 .
11. The fillable closure device with triggering pushbutton according to claim 1 , wherein the cap ( 1 ) is threaded onto a threaded portion of the connector ( 3 ).
12. The fillable closure device with triggering pushbutton according to claim 1 , wherein the separate container ( 2 ) is filled separately.
