  • Patent number: 6378573
    Abstract: A removing device for liquid in a flexible packing by means of which an unintentional escape of liquid and the ingress of air, dirt and microorganisms in the product accommodated in said packing can be prevented reliably and permanently. In order to achieve this, the removing device according to the present invention is provided with a tubular straw element including the inlet of the removing device and with a closure element associated with the outlet. The flexible packing according to the present invention, which is used for accommodating a liquid, is provided with an insertion area for inserting a removing device, said insertion area being defined by an opening formed in the envelope of said flexible packing and closed by a foil in the initial state, said foil being of such a nature that it will sealingly wrap itself around the introduced removing device thus forming a tentlike shape.
