The purpose of the invention is to create a packaging pouch possessing properties similar to an ordinary bottle, which stands steadily, is easy to use and pour from, is easy to open and close after opening, is suitable for carbonated liquids, and can also be fitted with various devices and applicators. The requirements were met by designing the packaging pouch in the shape of a bottle with a special neck shape (figure 1), which is self-closing and can also be sealed completely by folding and inserting the upper part under a cross strip attached to the neck of the bottle (figure 2). The usefulness of the pouch is greatly enhanced by providing the neck of the pouch with a lock ring (figure 10) with provision for fitting a screw cap, snap-action cap and many other devices (figure 4). The invention may be used as a packaging medium in almost all industries in which packages for hermetic sealing of liquids and dry materials are used.
