Oxygen-impereable, fillable closure with a push button for triggering

摘要

A fillable closure is used to initiate emptying of a separately fillable capsule molded into this closure. The capsule is made oxygen-impermeable on the inside or outside with a vapor-deposited layer of silicon dioxide or metal. The volume of the capsule can be reduced through pressurization 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.

主权项

1. A fillable closure comprising:
a fillable capsule (2) moulded into the closure that is in a form of a cap and configured to connect to a bottle neck, the capsule filling up an inside of the closure in a form of a dome, and the capsule having a coating of metal or silicon dioxide on either an inside or an outside, or on both sides thereof, the capsule (2) comprising: an open bottom sealed by an oxygen-impermeable sealing foil (6) after filling the capsule; a top positioned at an upper end of the closure forming a pusher surface (7) functioning as a push-button of the closure to initiate emptying the capsule; a protruding element (8, 27, 30) formed on an underside of the pusher surface (7) configured to open the sealing foil (6) on the bottom of the capsule; a deformable front and side wall (11) and a rigid rear wall (13) that is not deformable; an upper edge (10) of the rigid rear wall forming a stationary pivot hinge on which the pusher surface (7) can be pivoted downward through deformation of the front and side wall (11); wherein under pressurization on the pusher surface (7), the front and side wall deform below the upper edge of the rigid rear wall, causing opening the sealing foil (6) by the protruding element.
