Abstract
The present invention relates to a closure including a first stationary part and a second removable part. The second part includes a storage chamber and a dispensing opening. The first part includes a closing member and at least one passage opening. Upon first opening, the second part moves relative to the first part from a first configuration to a second configuration to cause the dispensing opening to disengage from the closing member and allow the product in the storage chamber to flow out into the container. In the first configuration, the first part engages the second part to form a first sealing portion, a second sealing portion, and a safety chamber arranged between the first sealing portion and the second sealing portion.
