Definitions

  • the invention relates to a two-chamber package according to the preamble of patent claim 1.
  • Two-chamber packs of this type are used wherever different types of contents have to be stored and may only be brought together immediately before they are used. As an example of this, only hair dyes and the like are mentioned here.
  • Essential requirements for such two-chamber packs are, on the one hand, constructive simplicity and the associated low manufacturing costs, and on the other hand, handling that is as simple and safe as possible, while at the same time ensuring good mixing of the individual filling components.
  • FR patent specification 1 431181 represents the state of the art which corresponds to the preamble of patent claim 1.
  • a two-component pack which consists of two separate aerosol containers, each of which contains one of the contents components together with a propellant.
  • the two containers are matched in terms of shape and can e.g. can be coupled together by screwing. They are each equipped with a valve on the facing surfaces, which open automatically when the two containers are coupled together.
  • the contents of the container under the greater pressure are then emptied into the other container and the two filling material components mix there.
  • This other container is provided with a conventional dispensing valve, by means of which the two filling material components can then be dispensed in a mixed form.
  • the disadvantage of this two-component pack is that it is structurally quite complex and also relatively difficult to handle.
  • FIG. 3718235 Another two-chamber aerosol package is known from US-PS 3718235.
  • an inner container which is closed by an attached lid, is located in an outer container which contains the filling material component and a propellant gas.
  • a spiral spring is held under tension in the inner container, which, when released, blows the lid off the container.
  • the spring is held under tension by two legs of a spring clip that are spread apart by a metal ball. By shaking or pounding the entire package, the ball can be thrown out of the clamp due to inertia, whereby its legs release the coil spring and this finally opens the lid of the container.
  • the two-chamber package according to this US patent does not ensure sufficient security that the inner container opens unintentionally and the two contents are prematurely mixed.
  • this pack is relatively cumbersome to handle and the mixing of the contents does not take place automatically, but requires manipulations such as shaking movements and the like.
  • an aerosol two-component pack which has two flexible inner containers arranged one inside the other in a stable outer container, the two filling material components in one of the two inner containers and the propellant in the space between the larger one Inner container and the outer container.
  • a conventional aerosol valve is embedded in the lid of the package designed as a conventional aerosol container (spray can).
  • a second valve, which closes the innermost container, is coaxially attached to this valve via an adapter. Both valves are connected via a push rod in such a way that when the outer valve is opened, the inner valve is also opened after a slight delay. When the outer valve is released, the inner valve closes again.
  • the two valves and their connecting adapter are designed in such a way that the two filling material components are brought together in the adapter when the valves are opened and are released together through the outer valve. Only the dispensed quantities of the filling components are mixed, the remaining quantities remaining in the package remain unmixed in their respective containers. However, this two-component package does not empty one container into the other container and thus mix the total contents of both containers.
  • Another type of two-component package is also known from DE-A-1 801 518.
  • this pack one of the filling components is located in a glass ampoule arranged in the spray can, which can be broken up by means of a tappet coupled to the dispensing valve.
  • This two-component pack has not proven itself in practice for various reasons and has not been able to establish itself.
  • DE patent no. 1 929 844 also shows a two-component pack which is largely similar to that in the already mentioned FR patent application 2 015 337. In this pack, too, the total quantities of the two filling material components are not mixed, but only the quantities of filling material dispensed are mixed with one another immediately before the dispensing.
  • US Pat. No. 3,080,094 describes a two-component package in which the the two filling components are separated by a membrane in the aerosol container. This membrane can be broken open by a piercing member connected to the dispensing valve, whereby the two components then mix.
  • This pack also has various disadvantages and therefore has not proven itself in practice.
  • a further two-component pack is known from US Pat. No. 3,773,264, in which, similarly to the pack of the already mentioned US Pat. No. 3,718,235, a filling component is located in a separate container in the spray can.
  • This container has a spring-loaded lid that can be opened by a trigger mechanism.
  • the trigger mechanism is actuated by a ball, which can be made to strike the trigger mechanism by suitable shaking movements of the spray can.
  • This known pack is equipped with securing means against unintentional opening of the inner container, but it is structurally quite complicated and also cumbersome to use.
  • European Patent Application No. 0024 659 published under No. 80 10 4853.9 describes a two-chamber package, which comprises an outer and an inner container for a filling component and a compressed gas. Both containers are under the same internal pressure.
  • the inner container is closed by a sliding piston. By releasing part of the compressed gas from the outer container, the piston in the inner container is displaced due to the pressure imbalance and thereby opens communication openings to the outer container, so that the filling material components can mix.
  • the present invention is now intended to create a two-chamber pack which is suitable for dispensing the filling material in aerosol form and which particularly meets the requirements mentioned at the outset.
  • the package should be able to be implemented using the standard components used in aerosol technology as far as possible and thus be cost-effective to produce. Another requirement is that the package should preclude incorrect manipulation as far as possible or that incorrect manipulation should not have any adverse effects.
  • the two-chamber pack shown in FIGS. 1 and 2 is the simplest embodiment. It comprises an outer standard aerosol container 1 with a standard aerosol valve 2, which is held in the usual way in a lid 4 tightly attached to the opening edge 3 of the container 1 and an inner standard aerosol container 5 with lid 6 and standard aerosol valve 7 contained therein.
  • Aerosol valves have an actuating and dispensing tube which can be moved axially inward against the restoring force of a spring or another elastic component for opening the valve and through which the filling material can be removed from the respective container.
  • the outer container 1 contains the filling component A
  • the inner container 5 contains the filling component B and a suitable propellant T, which generally contains an easily liquefiable gas, e.g. Freon or the like.
  • the dimensions of the containers depend on the volume of product to be dispensed and their ratio.
  • the maximum diameter of the inner container can be just as large as that of the opening edge 3 of the outer container, so that the inner container can still be inserted through this opening into the outer one. For the common sizes, this condition can usually always be met with standard aerosol containers.
  • the dispensing tube 8 of the valve 7 of the inner container 5 extends through the valve housing 9 of the outer valve 2 to the dispensing tube 10 of the latter, so that the two actuating and dispensing tubes are thus kinematically coupled.
  • the dispensing tube 8 has a lower, thicker section 8a and an upper and front, thinner section 8b, respectively.
  • a resilient bracket 11 sits on the thicker portion 8a of the tube 8. In Figures 1 and 2, this bracket 11 is shown separately for clarity.
  • the dispensing valve 2 of the outer container 1 is now briefly opened by pushing the dispensing tube 10 inward (FIG. 2). Due to the kinematic coupling of the two delivery tubes, the tube 8 of the inner valve 7 is also pressed in and the valve is opened. Due to the downward movement of the inner delivery tube 8, the clamp 11 comes into engagement with the thinner tube section 8b and, by being supported on the valve housing 9 of the outer valve 2, holds the inner valve 7 in the open position even when the tube 10 of the outer one Valve 2 has been released.
  • the filling material mixture A + B is now removed in the usual way through the outer valve 2, the container 1 being held with the valve 2 downward.
  • all of the propellant gas required for emptying the pack is originally in the inner container, while the outer container is depressurized.
  • the inner container then e.g. would have to be kept under a higher pressure by means of an additional nitrogen cushion or the like.
  • the inner and, if appropriate, also the outer container as a so-called two-chamber pack with a compressible inner bag, in which case the contents would be arranged in this bag and the propellant gas would be in the space between it and the container in question.
  • the inner container must be under a higher pressure than the outer container.
  • the inner container 5 is supported on the bottom of the outer container 1. If the length of the inner container is not sufficient for this, a corresponding base or the like can of course also be provided.
  • FIGS. 1 and 2 show four further exemplary embodiments of the two-chamber pack according to the invention.
  • the same or corresponding parts are provided with the same reference numerals as in FIGS. 1 and 2.
  • the dispensing valve 2 of the outer container 1 is a so-called high-performance type, in which the dispensing tube 10 is held in an elastic sleeve 14 such that it can be tilted and adjusted axially inward.
  • the inner container 5 is here rotated in a holding sleeve 15 by 180 ° relative to the outer container 1.
  • the sleeve 15 is attached to the opening edge 3 of the outer container 1.
  • the sleeve 15 sits tightly on the inner container 5 and holds it by friction. It is equipped in its upper area with openings 16 through which the contents of the outer container can reach its valve 2.
  • the dispensing tube 8 of the inner valve 7 is supported with its thicker section 8a on the bottom 17 of the sleeve and projects with its thinner section 8b through an opening 18 in the bottom 17. Further openings 19 in the bottom 17 prevent the formation of a pressure cushion in the lower part of the sleeve 15.
  • the dispensing tube 10 of the outer valve 2 does not rest on the bottom of the inner container 5, but is at a slight distance from it. This allows the outer valve e.g. to open the outer container for the purpose of filling with propellant gas, without opening the inner valve at the same time. With a suitable dimensioning of the individual components, the latter is only possible if the delivery tube 10 of the outer valve 2 is pressed completely inwards.
  • the inner container 5 is fastened to the housing 9 of the valve 2 of the outer container 1 by means of an adapter 20.
  • the adapter 20 is attached to an undercut neck of the valve housing 9 and engages behind an annular undercut of the lid 6 of the inner container with claws 21. Lateral openings 22 connect the valve 7 to the interior of the outer container.
  • a plunger 24 provided with a shoulder 23 is provided.
  • This shoulder 23 engages behind a shoulder 25 in when the outer valve 2 is actuated and thus the tappet 24 is pushed downward, due to the lateral deflection forces which are always present in practice Adapter 20 so that the tappet can no longer move back upwards when the outer valve is released and the inner valve 7 is thus kept open.
  • the inner container is surrounded by a corrosion protection sleeve 26 which is fastened by means of an adapter 27 to the housing 9 of the valve 2 of the outer container.
  • a plunger 28 couples the delivery tube 10 of the outer valve 2 to the bottom of the inner container 5, which is displaceable in the sleeve 26.
  • the delivery tube 8 of the valve 7 thereof is supported in a socket 30 of the corrosion protection sleeve 26 provided with a passage opening 29.
  • FIG. 6 shows an embodiment in which the dispensing valve 2 of the outer container 1 is again designed as a high-performance type.
  • the inner container 5 is arranged with its valve facing downward in a cup 32 closed at the bottom by means of a support base 31.
  • the base is provided with resilient locking cams 33, which are initially engaged in the lower of two circumferential grooves 34 and 35 in the cup 32.
  • the dispensing tube 8 of the inner valve 7 is supported on an intermediate wall 37 of the base 31 provided with an opening 36.
  • the base itself protrudes almost to the bottom of the outer container 1 or stands directly on it.
  • Figures 7 to 9 show a particularly useful embodiment of the two dispensing valves 2 and 7, which enables a structurally simple and inexpensive connection of the same.
  • the same or corresponding parts are identified in the same way as in the previous exemplary embodiments.
  • the general arrangement or design of the pack essentially corresponds to that according to FIGS. 1 and 2, ie. H. the inner container is supported directly or via a corresponding base or the like on the bottom of the outer container, so that the inner valve 7 reaches as far as possible directly to the outer valve 2.
  • Both valves 2 and 7 are essentially of the same design and, as is common with many standard aerosol valves, are held in their closed positions by a coil spring 2a or 7a.
  • the discharge tube 8 of the inner valve 7 protrudes into the housing 9 of the outer valve 2, corresponding to FIGS. 1 and 2. It has a conical seat 8c (FIG. 9) at its upper end, which cooperates with a cone 10b of the same kind on an inner extension 10a of the delivery tube 10 of the outer valve 2 and forms an intermediate valve therewith.
  • the delivery tubes 10 and 8 of the two delivery valves are equipped with a shoulder 10c and 8d, on the one hand, the coil springs 2a and 7a are supported and, on the other hand, the outward movement of the delivery tubes is limited.
  • a few axially parallel, somewhat flexible or deformable ribs 9a or 13a are formed on the inner circumference of the valve housings 9 and 13.
  • the ribs 9a of the outer valve 2 have no special function.
  • the ribs 13a of the inner valve 7 cooperate with the sawtooth-shaped shoulder 8d of the dispensing tube 8 of the inner valve 2 in such a way that the shoulder cuts into them when the dispensing tube 8 is pressed inward and thereby holds the dispensing tube in its pressed-in position , so that it can no longer press the spring 7a and the inner valve 7 thereby remains open (FIGS. 8 and 9).
  • valves according to FIGS. 7 to 9 is structurally particularly favorable and ver also avoids incorrect operation of the package, which could lead to the undesired leakage of the filling material or makes such incorrect manipulation ineffective.
