Definitions

  • the invention relates to a device for mixing and spraying one of at least two components, for. B. liquids and a propellant mixture, according to the preamble of claim 1.
  • Such devices are used wherever different types of product have to be stored separately and may only be mixed immediately before they are used. As an example of this, only hair dyes or the like are mentioned here.
  • the inner container is designed as an independent aerosol container provided with a separate dispensing valve, the inner container being under a higher internal pressure than the outer container and its dispensing valve communicating with the interior of the outer container in that the dispensing valve of the inner container is kinematically coupled to the dispensing valve of the outer container in such a way that, by normal actuation of the dispensing valve of the outer valve, the dispensing valve of the inner container is opened and that means are also present which hold the dispensing valve of the inner container in its open position . Proposed holding clips, locking cams, clamping sleeves or the like are suggested as such means.
  • the present invention has for its object to provide a device of the type mentioned in the preamble of claim 1, which is structurally simple and yet extremely reliable, and in which a defined fluid connection between the inner and outer container can be made so that a constant good mixing of the components is guaranteed.
  • the construction according to the invention according to claim 1 is characterized by the use of only a single dispensing valve, the valve body of which additionally assumes the function of the separate dispensing valve assigned to the inner container according to European Patent Application No. 82 102 599.6. Due to this constructive measure, the device according to the invention is characterized by a minimum of components with even increased functional reliability. There are no corrosion problems in the area of the discharge opening of the inner container, which could in any way affect the opening of the inner container. Finally, with the device according to the invention, a spontaneous and relatively large opening of the inner container is ensured represents, especially in the structural embodiment according to claim 7.
  • 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 held in a conventional manner in a lid 17 which is tightly fastened to the opening edge 15 of the container 10, and an inner container 12 which consists of a there is also corrosion-resistant material, like the outer container 10.
  • the outer container 10 contains a filling component A, the inner one Container 12 a product component B and a suitable blowing agent T, which is generally an easily liquefiable gas, for. B. butane-propane or the like.
  • the inner filling component can, for. B. hydrogen peroxide and the filling component Alein dye.
  • the dimensions of the containers depend on the volume of product to be dispensed and their ratio.
  • the maximum diameter of the inner container 12 can be just as large as that of the opening edge 15 of the outer container 10, so that the inner container 12 can still be inserted through this opening into the outer container. These dimensions are standardized for common sizes.
  • 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 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, as can be seen very clearly in FIGS. 2 and 3. As can also be seen very clearly in FIGS.
  • the opening edge 24 of the inner container 12 bears in a fluid-tight manner on the valve body 18 of the dispensing valve 14, an annular seal 34 being arranged between the valve body 18 and the opening edge 24, which is made of a preferably elastic and corrosion-resistant Material such as rubber or plastic.
  • the opening edge 24 of the inner container 12 on the side facing the ring seal 34 has a circumferential pressure rib 36 which is an absolute one Tightness guaranteed even at higher pressures.
  • the valve body 18 also serves as a closure 41 and upper holder (the valve body 18 is extended downward (extension 57) and can snap up and hold the inner container 12 for insertion into the outer container 10) of the inner container 12, the opening of the inner one Part 12 closing the container can be broken open by an actuating element 16 which is operatively connected to the dispensing tube 30 of the dispensing valve 14.
  • This actuating element is designed in the form of a crushing tip 44 - optionally provided with laterally formed knife-like blades - and molded onto the underside or the side of the delivery tube 30 facing the opening of the inner container 12.
  • the closing part of the valve body 18 is formed with the formation of a container outlet opening 26 as a discharge tube with a closure membrane 28, to which a hose-like riser pipe 50 extends, which extends to near the bottom 40 of the inner container 12.
  • the valve body 18 thus also serves as a kind of "closure cap” of the inner container with a closure membrane 28 which can be broken open by the breaking tip 44.
  • Valve body 18 each have a slightly smaller wall thickness than the other parts of the valve body 18 (about half of them), which means that when the inner container 12 is emptied, ie when the pressurized component B comes out of the inner container 12, a "spreading or "Widening" of the discharge opening 52. This results in a large-area discharge opening 52, which enables a relatively spontaneous and good mixing of the filling components A and B.
  • FIGS. 1 In the exemplary embodiment according to FIGS.
  • the inner container 12 is pressed with its opening edge 24 under the action of an elastic element 20 or 22 against the valve body 18, namely an annular shoulder 32 thereof.
  • the contact pressure of the elastic elements 20 and 22 is so great that a secure seal with respect to the filling space of the outer container 10 is obtained between the annular shoulder 32 of the valve body 18 and the opening edge 24 of the inner container 12, including the ring seal 34.
  • the inner container 12 is otherwise bottle-shaped.
  • the elastic element is formed by a pot-like holder 20 comprising the bottom region of the inner container 12 with feet 42 which are elastically supported with respect to the side and bottom wall of the outer container 10.
  • the pot-like holder 20 thus also serves to fix the inner container 12 within the outer container 10 and to press it elastically against the annular shoulder 32 of the valve body 18.
  • the inner container 12 or its opening edge 24 is pressed elastically against the annular shoulder 32 of the valve body 18 by a spring element, namely coil spring 22, which acts between the bottom 38 of the outer container 10 and the bottom 40 of the inner container 12
  • a spring element namely coil spring 22
  • the inner container 12 is fixed within the outer container 10 in the bottom region of the inner container 12 in the same way as in the embodiment according to FIG. H. by means of a pot-like holder comprising the bottom region of the inner container 12, which is supported by means of laterally formed feet against both the side and bottom wall 38 of the outer container 10.
  • the dispensing tube 30 Before the device or the two-chamber container is put into use, the dispensing tube 30 is in the position shown in FIG. 1 or FIG. 2. To mix the two filling material components A and B, the dispensing tube 30 of the dispensing valve 14 is pressed axially inward and the sealing membrane 28 is thus broken open. Since the outer container 10 is depressurized, the filling component A located in it does not escape despite the valve 14 being opened for a short time. As long as the dispensing tube 30 is pressed in with its breaking tip 44, it seals the opened dispensing opening 52 of the inner container 12 relatively well, so that the filling component B located in the inner container cannot escape from it (FIG. 3).
  • the device or the two-chamber container according to FIG. 4 in turn comprises an outer standard aerosol container 10 with a dispensing valve 14 which is held in a conventional manner in a lid 17 which is tightly fastened to the opening edge 15 of the outer container 10, and an inner container 12 which is made of a material which is as corrosion-resistant as the outer container 10.
  • the outer container 10 also contains, as in the previous embodiments a filling component A, the inner container 12 a filling 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 (as in the embodiments according to FIGS. 1-3).
  • 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 is designed as a closure hood which is placed over the opening edge 24 of the bottle neck 19.

  • the closure hood 41 is 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 clamped, 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 the lower support and centering of the inner container 12 within the outer container 10.
  • the contact pressure of this elastic element 20 is so great that a secure seal against 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, similarly to FIG. 2, 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 wall 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. 5 to 8).
  • 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 pressing of the inner container 12 or its opening edge 24 against the closure hood 41 and thus against the valve body of the dispensing valve 14 can also by an effective between the bottom of the outer container 10 and the bottom of the inner container 12 spring element, for. B. coil spring, take place similarly to Fig. 3rd
  • the delivery tube 30 Before the device is put into use, the delivery tube 30 is in the position shown in FIGS. 4 and 5.
  • 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 6.
  • the closure membrane 28, as can be clearly seen in FIGS. 5 to 8, is an integral part of the closure hood 41 and is connected to it by 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 6).
  • a conventional riser tube 50 is connected to the passage defining the container outlet opening 26.
