Definitions

  • the invention relates to a device for producing and spraying a mixture consisting of at least two components, for example liquids, and a mixture consisting of propellant gas, according to the preamble of patent claim 1.
  • EP-A 98 476 shows a device for dispensing a highly viscous filling material with two containers arranged one inside the other with a dispensing valve comprising a valve body and a dispensing tube movably mounted therein, with the closure of the inner container in the form of a closure membrane in such a way it can be acted upon that the closure membrane can be pushed or pressed into the inner container during normal actuation of the delivery tube, the closure membrane being assigned an opening of the inner container, and this opening means for fixing the pressed-in closure membrane while forming and maintaining one Has fluid connection through the opening.
  • the inner container is used to hold highly viscous contents; the outer container contains a pressurized propellant.
  • the inner container is delimited by a flexible wall, so that when the dispensing valve is opened, the filling material is discharged from the inner container by the pressure medium acting on the flexible wall thereof.
  • the closure membrane assigned to the opening of the inner container serves to prevent easily volatile substances in the filling material from diffusing out. The closure membrane is pressed into a position closing the associated opening by the excess pressure prevailing in the inner container, forming a mere contact seal. This does not ensure an absolutely tight seal.
  • the present invention has for its object to provide a device of the type mentioned in the preamble of claim 1, which is not only structurally simple, but is also extremely reliable, in which in particular a defined fluid connection between the inner and outer container are made and maintained can, essentially regardless of whether the sealing membrane is pushed in more or less.
  • This object is achieved by the characterizing features of patent claim 1.
  • the means for fixing the pressed-in closure membrane which is assigned to the opening of the inner container and designed according to the invention, ensures that the predetermined fluid connection between the inner and outer container is maintained after opening of the inner container, regardless of how far the closure membrane has been pressed in. It is held in any depressed position while maintaining fluid communication.
  • valve body of the dispensing valve arranged on the outer container also serves as a closure of the inner container, the opening edge of the inner container abutting the valve body in a fluid-tight manner.
  • the sealing membrane is then an integral part of the valve body.
  • the device or the two-chamber container according to FIG. 1 comprises an outer standard aerosol container 10 with a dispensing valve 14 which is conventionally contained in a lid 17 which is tightly fastened to the opening edge 15 of the outer container 10, and an inner container 12 which also consists of a Corrosion-resistant material is like the outer container 10.
  • the outer container 10 contains a product component A
  • the inner container 12 contains a product component B and a suitable propellant T.
  • the dispensing valve 14 fastened in the cover 17 consists of a valve body 18 and an actuating and dispensing tube 30, which is axially movable in this, through which the mixture can be removed from the containers 10, 12.
  • the delivery tube 30 is still closed with a cap 39.
  • the dispensing tube 30 can be moved axially inward against the action of a helical spring 46, the helical spring 46 being supported on the valve body 18 on the one hand and on an annular shoulder 48 formed on the dispensing tube 30 on the other hand.
  • the valve body 18 is anchored in the cover 17 in a positive and non-positive manner.
  • the inner container 12 is designed in the manner of a bottle with a tapered bottle neck 19.
  • the closure 41 of the inner container as shown very clearly in FIGS.
  • closure hood which is placed over the opening edge 24 of the bottle neck 19.
  • the fluid seal between the interior of the inner container and the interior of the outer container takes place by means of an annular seal 34 arranged between the opening edge 24 and the closure hood 4, the additional function of which is explained in more detail with reference to FIGS. 4 and 5.
  • 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 serves for lower support and Centering of the inner container 12 within the outer container 10 is used.
  • 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 cap 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 its opening edge 24 against the closure cap 41 and thus against the valve body of the dispensing valve 14 can also be achieved by a spring element acting between the bottom 38 of the outer container 10 and the bottom 40 of the inner container 12, e.g. 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 filling len of the inner container 12 with propellant gas (arrow 21 in Figure 4) through the passages 58, the ring seal 34 is pressed inward into the annular gap 13 with the formation of a fluid connection between the passages 58 and the annular gap 13.
  • the ring seal 34 therefore has a double function .
  • ball check valves or check membranes could also be arranged in the passages 58.
  • the embodiment shown in FIGS. 4 and 5 with the ring seal 34 is the simplest possible solution in terms of design effort.
  • closure 41 according to FIGS. 1-5 could also be formed as an integral part of the valve body 18.
  • the closure 41 of the inner container 12 for the purpose of filling it with propellant gas has three outer longitudinal grooves 51, 53 and 55 arranged uniformly distributed over the circumference, each of which almost overlaps the entire length of the fully assembled or closed state after filling (see FIG. 7) of the inner container 12 extends into this projecting closure section 47.
  • the inner container 12 is filled as follows:
  • the liquid component B is filled into the inner container 12. 6 is inserted into the opening of the inner container 12 designed in the manner of a bottle neck 19, in such a way that the longitudinal grooves 51, 53 and 55 ensure a fluid connection between the interior of the inner container and the external environment is. Then liquid propellant is filled into the interior of the inner container 12 through the longitudinal grooves 51, 53, 55 by means of a filling head (arrows 21). After the filling has been completed, the closure 41 is pushed or pressed completely into the opening of the inner container 12 according to FIG.
  • the ring seal 34 comes in the closed state of the inner container 12 with the opening edge 44 on the one hand and with one on the closure 41 arranged annular shoulder 11 on the other hand in a fluid-tight system (see FIG. 7), the annular shoulder 11 on the side facing the annular seal 34 having a circumferential pressure rib 49 which ensures absolute tightness even at higher pressures inside the inner container.
  • the longitudinal ribs 6 are intended to hold the closure 41 in a fluid-sealing manner only in the opening of the inner container 12 until the inner container 12 is inserted into the outer container (not shown in FIGS. 6 to 8) and is fixed therein.
  • a permanent fluid seal between the interior of the inner container and the interior of the outer container is ensured only by clamping the closure 41 between the opening edge 24 of the inner container 12 and the valve body of the dispensing valve.
  • the three longitudinal ribs 33, 35 and 37 each extend downward from the annular shoulder 11 towards the free end of the closure section 47 projecting into the container opening, the longitudinal extent 29 of the ribs 33 being shown , 35, 37 corresponds approximately to half the length of the closure section 47 projecting into the container opening or the inner container 12.
  • cap-like closure membrane 28 and the connection thereof with the rest of the closure body via the predetermined breaking point 43 and the membrane fixing ribs 45 correspond to the embodiment according to FIGS. 1 to 5.
