FIELD: transportation; package.
SUBSTANCE: propellant is introduced under pressure around stem (15) of valve, outside gasket (21) of stem and down, in space of capacity of packet soft outside (17). Product is introduced under pressure via stem of valve into packet. Valve stem has external intermediate annular surface (34) in the form of truncated cone, and body (16) of valve has internal annular surface (35) in the form of truncated cone. Both surfaces are engaged in annular sealing contact, closing propellant access to packet, when stem of valve is deeply pressed in the first specified position for introduction of propellant under pressure. Groove of stem external surface interacts with radially displaced spring-loaded sliders, blocking stem in the second less pressed specified position for introduction of product via stem down into packet.
EFFECT: simple and efficient device for introduction of propellant and product under pressure in any order with application of ordinary equipment for pressure filling after valve has been installed on reservoir and packet is installed on valve.
