FIELD: transportation; packing.
SUBSTANCE: self-sealing metering valve contains circumferential affixed part, by means of which it is fixed dose structure, through which production is back off from its source. Flexible circumferential sleeve pass from circumferential attaching part. Flexible elongated head is located sideways from circumferential sleeve. Head allows thickness and at least one elongated slot, determinative two opposite discovered sections. Central elongated part of circumferential sleeve allows two located at a distance from each other elongated side walls. Each of two shorter end parts of circumferential sleeve contains end wall, connected to side walls. Each end wall allows strict section between two crooked section, each of which is connected with one of side walls. There are provided more three versions of valve implementation.
EFFECT: convenience increasing in usage and expansion of operational functionalities.
