  • the closure cap 41 is clamped between the opening edge 24 of the inner container 12 or the ring seal 34 and the valve body 18 of the dispensing valve 14, the clamping effect being achieved by an elastic element acting on the bottom of the inner container 12, which at the same time provides lower support and centering the inner container 12 within the outer container 10.
  • the contact pressure of this elastic element 20 is so great that a secure seal with respect to the filling space of the outer container 10 is obtained between the closure cap 41 and the opening edge 24 of the inner container 12, including the ring seal 34.
  • the elastic element 20 is formed by a pot-like holder comprising the bottom region of the inner container 12 with feet 42 which are elastically supported with respect to the side and bottom walls of the outer container 10.
  • the pot-like holder also serves to fix the inner container 12 within the outer container 10 and to press it elastically against the closure 41 or valve body 18 of the dispensing valve 14.
  • the lower edge of the closure hood 41 is provided with inwardly projecting latching cams or an inwardly projecting latching bead 23 which engage behind the opening edge 24 (see FIGS. 2 to 5).
  • the actual fixing of the closure hood 41 in the filled state of the two containers takes place — as explained above — by the clamping between the opening edge 24 of the inner container 12 and the valve body 18 of the dispensing valve 14.
  • the elastic pressure of the inner container 12 or the opening edge 24 against the closure cap 41 and thus against the valve body of the dispensing valve 14 can also by an effective between the bottom 38 of the outer container 10 and the bottom 40 of the inner container 12 spring element, for. B. coil spring.
  • the delivery tube 30 Before the device is put into use, the delivery tube 30 is in the position shown in FIGS. 1 and 2.
  • the dispensing tube 30 of the dispensing valve 14 is pressed axially inward and a closure membrane 28 designed here in the form of a cap is pushed into a central passage, breaking open an annular predetermined breaking point 43, which, in the exemplary embodiment shown, the component outlet opening 26 of the inner container 12 defines and is an integral part of the closure cap 41.
  • the broken or opened state of the inner container 12 is shown in Figure 3.
  • the closure membrane 28, as can be clearly seen in FIGS. 2 to 5, is an integral part of the closure hood 41 and is connected to it via a predetermined breaking point in the form of an annular weak point 43.
  • the closure membrane 28 pushed or pressed into the opening 26 by means of the delivery tube 30 is held in this opening by three longitudinal ribs 45 which are evenly distributed over the circumference, forming a defined fluid connection between the interior of the inner container and the interior of the outer container (arrow 27 in Figure 3).
  • a conventional riser tube 50 is connected to the passage defining the container outlet opening 26.
  • the double function of the ring seal 34 will be explained in more detail with reference to FIGS. 4 and 5.
  • the ring seal 34 thus also acts as a check valve.
  • the closure hood 41 has openings 58 which are in the region of an annular gap 13 between the central passage defining the container opening 26 and the bottle neck 19 of the inner container 12 lie.
  • the closed position of the ring seal 34 is shown in Figure 5.
  • the propellant gas located inside the inner container 12 presses the ring seal 34 upward in such a way that the passages 58 in the closure hood 41 are closed.
  • the direction of pressure of the propellant gas T is identified by the arrows 31 in FIG.
  • the ring seal 34 When the inner container 12 is filled with propellant gas (arrow 21 in FIG. 4) through the passages 58, the ring seal 34 is pressed inward into the finger gap 13 with the formation of a fluid connection between the passages 58 and the ring gap 13.
  • the ring seal 34 accordingly has a Dual function.
