Definitions

  • the invention relates to a device for dispensing gaseous, liquid or powdery substances according to the introductory part of claim 1.
  • the liquid substances also include those soft, cream-like and foamy or foamable substances of corresponding viscosity, which are by means of the proposed device can be spent.
  • a wide variety of methods and devices are known for spraying and dispensing various substances, the working principle of which generally resembles either the siphon bottles or the spray cans.
  • the common characteristic of the known solutions consists in the presence of a pressure vessel which is suitable for holding the substance to be dispensed, an overpressure being generated in the pressure vessel by means of a corresponding propellant, namely a propellant gas.
  • the excess pressure serves to squeeze the substance out of the pressure vessel and the substance leaves its interior under the influence of the excess pressure via a valve or via another suitable opening.
  • the siphon bottles are fed with the propellant gas from outside the pressure vessel.
  • the pressure vessel can be refilled several times with the substance to be dispensed and used several times with the help of new propellant gas to spray out the substance.
  • This solution is particularly advantageous in the event that a relatively large amount of the substance is to be prepared for spraying and / or that a chemical reaction of the substance to be sprayed out with the propellant gas is to take place in the bottle forming the pressure vessel.
  • the characteristic feature of the spray cans is that the spray material is filled under an overpressure: the pressure vessel is filled with both the substance to be sprayed and the propellant gas at the same time. Since refilling spray cans is very difficult, the spray cans can generally only be used once and should be discarded after use.
  • Fluorocarbons are used as propellants in spray cans.
  • the fluorocarbons are chemically inert and, as inert gases, they would be very advantageous as propellants.
  • the fluorocarbons are very dangerous for the atmospheric ozone layer and therefore for the whole world and for civilization.
  • the presumably negative impact of fluorocarbons appears to be so dangerous that their use has been banned in several countries. This trend is expected to intensify all over the world.
  • the spray cans are relatively expensive: the packaging represents a disproportionately high value compared to that of the substance to be dispensed because the uniqueness of the application - if the safety requirements are met - significantly increases the size of the Manufacturing costs leads.
  • Another problem is to destroy a large amount of the emptied bottles. Destruction can be very difficult, especially if the spray cans have been filled with an explosive or highly flammable propellant, since the remaining unavoidable propellants in the cans can lead to accidents if the cans are not opened carefully enough.
  • a device designed as a spray can is already known with the features from the introductory part of claim 1 (DE-A-2 004 856), which is characterized in that the propellant is in one of the subspaces which is used to hold the substance to be dispensed , is housed by means of the piston separate other sub-space, regardless of the compatibility of the blowing agent with the substance to be dispensed in connection with cheap, non-polluting or non-polluting blowing agents can be used.
  • the invention solves the problem of making the pressure vessel reusable in a device of the type mentioned at the outset and, in addition to the propellant (the propellant gas), also arranging the substance to be dispensed in independent, cheap and disposable packaging after use and in the pressure vessel to use the excess pressure of the blowing agent to open the fabric container inside the pressure container.
  • the propellant the propellant gas
  • the discharge opening of the pressure container can be equipped with an atomizer.
  • the fabric container can be provided with an elastic jacket that presses against the inner wall of the pressure container under the influence of excess pressure.
  • a blowing agent z. B. compressed air or another appropriately cheap gas can be used.
  • the selection of the blowing agent is facilitated by the fact that it does not come into contact with the substance to be dispensed. Under certain conditions, it can also be advantageous if a chemical two-component system that becomes effective under pressure development is used as the blowing agent.
  • the pressure vessel should not be thrown away or destroyed after the emptying of the fabric container, because the device can be put back into operation and used very easily after removing the emptied fabric container and the used propellant container and after inserting the new container.
  • the containers can be made from cheap materials with an aesthetic, pleasing exterior design, the application of the invention creates the simple and inexpensive possibility of realizing a new family of interchangeable elements (containers) of commercial products.
  • the containers pose only the same environmental problems as the other well known plastic packaging.
  • the device which is shown in the drawing has a pressure container 5 which is provided on the one hand with an outlet opening and on the other hand is closed with a closure cap 13.
  • the dispensing opening is formed in the device shown by means of a puncture tube 4, a valve 3 and an atomizer 2 supported on a spring 1.
  • the elements 1 to 4 shown together form a valve device.
  • the cap 13 is tightly connected to the pressure vessel by means of a sealing washer 7.
  • a screw closure as shown in the drawing, or a bayonet closure, not shown in the drawing, or another suitable closure unit can be used.
  • a vent valve 14 communicating with the interior of the pressure vessel 5 and a lancing unit consisting of a needle 6 and a pressure actuating plunger 8 are arranged in the manner shown.
  • a substance container 9 containing the substance 10 to be dispensed is arranged in the partial space of the pressure container 5 adjacent to the discharge opening.
  • the fabric container 9 is designed such that it has a wall that withstands the excess pressure on its front side facing the closure cap 13, and has an easily pierceable or tearable wall on its front side facing the valve 3 or the discharge opening.
  • the fabric container 9 can be provided in the manner shown in the drawing with a rigid wall 15 and / or with an elastic sliding jacket 16. Both the rigid wall 15 and at least the annular lip formed on the free edge of the sliding jacket 16 are adapted to the diameter of the inner wall of the pressure vessel 5 in such a way that they are airtight under pressure but slidably bear against the inner wall.
  • the sliding jacket 16 also forms a holder for the propellant container 11.
  • the propellant container 11 containing a fuel 12, for example compressed air, is inserted.
  • the propellant container 11 has on its end facing the closure cap 13 a wall which can be pierced by means of the needle tube 6.
  • the needle 6 is inserted into the wall of the propellant container 11 by means of the pressure actuating plunger 8.
  • the rigid wall 15 or the sliding jacket 16 are placed close to the inner wall of the pressure vessel 5, so that the propellant cannot escape to the dispensing opening. Under the influence of the excess pressure, the fabric container 9 begins to move towards the dispensing opening.
  • the neighboring end wall of the fabric container 9 is pierced by means of the piercing tube 4, so that the interior of the fabric container 9 is thereby connected to the dispensing opening.
  • the overpressure causes the substance 10 to be dispensed to flow out of the substance container 9 through the dispensing opening and possibly the atomizer 1.
  • the wall element separating the interior of the pressure container 5 into two subspaces slowly moves in the direction of the emptying of the substance container 9 moved the dispensing opening. After the substance has been sprayed out, the excess pressure can be compensated by corresponding actuation of the vent valve 14 in order to release the remaining propellant 12.
  • the empty containers 9, 11 can be removed from the pressure container 5 and exchanged for new containers.
  • the two composite containers 9, 11 act as a piston, with which the pressure vessel 5 cooperates as a cylinder.
  • the fabric container 9 may be deformable in such a way that that it is increasingly compressed on the end wall of the pressure vessel 5 having the valve 3 with increasing release of the substance 10 and its volume is thereby reduced.
  • a pressure vessel which has an outlet opening in the form of a valve and a lower closure cap and a lancing unit arranged in the closure cap.
  • the propellant and the substance to be dispensed should be arranged in appropriate containers in the pressure container such that the substance container is closer to the valve and the propellant container at least partially fills the remaining part of the pressure container.
  • the substance container or the fuel container should be designed on their contact surface in such a way that the airtight separation of the two subspaces is ensured on this surface.
  • the pressure vessel is sealed airtight using the cap.
  • the propellant container is opened with the aid of the lancing unit, so that the excess pressure is released.
  • the excess pressure causes the fabric container to move in the direction of the valve.
  • the valve can e.g. B. be provided with an inlet tube which can be pushed through the wall of the fabric container and can be immersed in the fabric container. The substance to be dispensed is sprayed out through the opening of the valve under the influence of the excess pressure.
  • the pressure container can also be provided without the valve, but only with an open dispensing opening, so that the substance is dispensed through the opening immediately after the propellant container is pierced.
  • Another possibility is to assemble the pressure container from two container parts and, on the one hand, to achieve the airtight closure of the pressure container and, on the other hand, to puncture the propellant container by assembling the container parts.
  • the common contact surface of the containers can be formed by a movable partition wall of the containers and the dispensing opening can be covered with an easily tearable layer.
  • the device assembled in this way can be used once: the dispensing opening is opened under the influence of excess pressure and the material can be sprayed out in a continuous flow in the desired direction.
  • the invention enables the construction of effective devices with simple, cheap, easily manufactured components.
  • the containers can be thrown away after use.
  • the blowing agent used is selected from cheap, non-polluting substances, in particular from appropriate gases. Therefore, the device does not pose a risk of explosion and fire if it is subsequently opened violently. Material containers with different materials can be used.
  • prefabricated substance and propellant containers can be used in different aesthetic designs and simple measures can be taken to be able to reliably check the content at any time (the content of the spray cans cannot be checked).
  • the fabric container can also contain the propellant container as an attached component.
  • the design of the fabric container and the propellant container as a structural unit leads to further simplifications in the distribution, transport and use of the device.
  • the device according to the invention can be manufactured 50 to 80% cheaper.
  • the disposable packaging of the fabric container and the propellant container mean a relatively low risk of pollution for the environment in comparison with the spray cans; in addition, the blowing agent can be selected from gases that are biologically and ecologically reliable and safe.
