Definitions

  • the invention relates to an aerosol can o Wall are separated from each other, which can be opened at least one point.
  • a pack of activating agents for one-component polyurethane foam is known from German Offenlegungsschrift 2 917 495.
  • This pack consists of a pressure container in which the activating agent and a propellant are provided under increased pressure.
  • the primary product for the one-component polyurethane foam is in an aerosol can, which is under less pressure. It is therefore possible to drive the activating agent into the aerosol can under the higher pressure of the propellant by connecting the discharge valves of the two pressure vessels.
  • polyurethane foam precursors are available in various can sizes and the size of the associated additional containers varies accordingly, there is a risk that consciously or unconsciously confusion will occur, individual additional containers will be lost or additional containers that are too large in relation to the aerosol can will be used, which are then only partially used these are emptied, which all means that the polyurethane foam is not formed with the formulation which is essential for achieving the desired properties. Even with the cans known from German Offenlegungsschrift 1 959 925, correct mixing is not always guaranteed.
  • the invention is therefore based on the object to provide a combination of an aerosol can or a similar pressure container for dispensing pressurized liquids with an additional container, in which a clear assignment is ensured, so that it is always possible to find the right additive in the right one Mix amount with the content of the aerosol can.
  • a complete union of the contents of the can and the contents of the container should certainly be possible.
  • the invention is characterized in that the space of the additional container available for receiving an additive is scalable down.
  • the additional container is therefore an integrated part of the aerosol can. This makes it much easier to handle the combination, at the same time preventing mix-ups and also removing the possibility for the processor to make changes to the combination of the two containers, thereby avoiding incorrect mixing.
  • the space of the additional container available for receiving the additive can be reduced, preferably down to zero.
  • This reduction in the volume of the additional container makes it possible to dispense its contents into the aerosol can in a defined manner, so that the can space is available as a common space for the contents of both containers.
  • the volume of the additional container is generally 5 to 20%, preferably approximately 10%, of the volume of the aerosol can.
  • the volume ratio can be different and is adapted to the particular application. It is also z. B. possible to keep only one thinner in the additional container, which can be mixed with the contents of the can if necessary.
  • the combination of aerosol can and additional container according to the invention can also be used in an outstanding manner for the production of a two-component foam or for the separate storage of its components.
  • the contents of the aerosol can and the contents of the additional container are separated from one another by a common wall which can be opened at least at one point, so that the mutual mixing can take place.
  • the opening can take place, for example, by tearing open, breaking through, puncturing, for which purpose appropriate devices are provided.
  • the common wall advantageously has at least one releasable closure, which preferably cannot be closed again, so that the space of the additional container is permanently connected to that of the aerosol can or its contents can be transferred into it.
  • the common wall can be opened by a pressure exerted by the interior of the container on the wall, in particular on a closure, which is preferably a pneumatic and / or hydraulic pressure.
  • This pressure is expediently generated only when necessary.
  • the pressure in the container is usually at most the same, preferably a lower, pressure than in the aerosol can.
  • the additional container therefore preferably contains no propellant or compressed gas.
  • the additional container is considerably smaller than the aerosol can. Therefore, in a preferred embodiment of the invention, the additional container is arranged in the can itself.
  • the additional container can advantageously be firmly connected to the can, in particular to the bottom of the can.
  • mechanical links which serve to dispense the contents of the container or to open the container can preferably be passed through the can wall and / or container wall at the connection point.
  • the additional container is formed by a pressure cylinder, one end of which is provided with a releasable closure and in which a pressure piston which is displaceable in the direction of the closure is arranged in a sealing manner.
  • the thus variable space for the content of the additional container is located between the pressure piston and the closure.
  • the pressure piston can be moved mechanically, preferably by means of a plunger, in particular a screw spindle, in the direction of the closure.
  • the plunger is passed through the container wall, preferably at a point at which the additional container is connected to the can with the formation of a seal to the outside, in particular on the bottom of the can.
  • the pressure cylinder preferably its end facing away from the closure, is sealingly attached to the edge of an opening provided in the container wall, and the plunger is guided through this opening into the pressure cylinder.
  • the fastening of the printing cylinder on the edge of the wall Opening can be done with the help of a rubber seal, for example by screwing or bracing.
  • the length of the plunger is advantageously dimensioned such that the closure can also be mechanically pressed out of the cylinder by means of the piston.
  • the drawing shows a longitudinal section through an embodiment of the invention.
  • an aerosol can having a volume of approximately 300 ml for a one-component polyurethane foam pre-product is provided as the storage container for the liquid to be dispensed.
  • the can can of course be larger or smaller.
  • the can 1 is tapered on its dispensing side in the usual way and is sealed there with a so-called clinch cover 2, which carries a conventional aerosol tilting valve 3.
  • the aerosol can is formed in one piece, i. H. the bottom 4 of the aerosol can, which is slightly drawn in, merges seamlessly into the cylindrical outer jacket 5 of the can.
  • the bottom can also be designed as a separate cover and connected to the jacket in a sealing manner.
  • a sealed additional container 6 which is arranged coaxially with the aerosol can and protrudes into the interior of the aerosol can from the bottom 4 to which it is attached.
  • a threaded end 7 is passed through a bore 8 in the can bottom 4 and rests with a shoulder 9 with the interposition of a rubber seal 10 sealingly against the edge of the bore.
  • a threaded nut 11 screwed onto the end 7 of the additional container 6 ensures a tight, sealing fit.
  • the additional container 6 has a cylindrical wall 18. Its outer diameter is approximately 1/3 of the diameter of the can.
  • the end 12 of the additional container 6 facing away from the bottom 4 is closed with a conventional plastic stopper 13, which has lateral sealing lips 14, and with its widened outer edge 15 rests on the end face of the cylindrical additional container, so that it cannot be pressed into the container .
  • a cylindrical thrust piston 16 which is sealingly guided in the cylindrical additional container. The space in the additional container between stopper 13 and thrust piston 16 serves as a space separate from the space of the aerosol can for storing a liquid to be mixed with the content of the aerosol can.
  • a feed screw 17 is used to advance the pushing piston 16 in the direction of the plug 13, which extends through the end 7 of the additional container attached to the can base and into a corresponding counter thread is guided.
  • the length of the spindle is measured so that the piston 16 can be guided close to the end 12 of the additional container 6.
  • the contents of the additional container can be completely dispensed, which is particularly advantageous for pasty masses.
  • this is not necessary, since the plug 13 is pressed out after a short advance of the thrust piston 16 by the pressurized liquid in the additional container, so that it can flow out and mix with the contents of the aerosol can. Since the aerosol can is not completely filled anyway for safety reasons, such mixing is possible in a simple manner.
  • the additional container protrudes from the bottom 4 to approximately the center of the aerosol can 1 and its space available for receiving the additional liquid corresponds to approximately 5 to 10% of the remaining interior of the aerosol can.
  • This volume is sufficient to accommodate an accelerator which is mixed with the polyurethane foam pre-product shortly before it is dispensed, in order to achieve faster curing if desired.
  • the combination of aerosol can or other pressure container and additional container according to the invention can also be used for mixing other liquids to be dispensed from the pressure container. If it is desired to gradually or intermittently empty the contents of the additional container into the aerosol can, the one with the plug 13 or.
  • Another openable closure provided opening of the additional container can also be kept very small, so that after opening the closure only the liquid part that exits from the additional container Feed of the pushing piston 16 is pressed out of the additional container by the corresponding volume reduction.
  • the opening formed in the additional container by removing the closure is of the same order of magnitude as that of the additional container.
  • Conventional aerosol cans can be used for the invention, the bottom or bottom cover of which is opened for the insertion of the additional container, whereupon the additional container is sealingly attached to the can base. This avoids the complex construction of the known can combinations.
