In addition to overdosing and increased perfume consumption, which results in an increased economic burden for the user, the more frequent need to refill the container inevitably shortens its usability. This is also negatively influenced by the removal valve, which is essential for the usability of the container, by the implementation and after. Completion of the gassing, necessary removal and replacement of the spray head, by inserting it at an angle or by using the valve of the propellant gas Eaciifüllpackunt becomes damaged, rendering the container unusable. The propellant gas filling is also made more difficult because the drain and fill valve must be mechanically operated on both sides, for which a force of at least 4 kg is required. In order to achieve the lowest possible delivery rate per unit of time, the flow cross-sections of the extraction valve should be made as small as possible, so that the propellant gas incidence time is relatively long and the flow rate of the gas is low. As a result, and in connection with the long Veg of the propellant gas through the ".Int took valve and the riser pipe, there is insufficient mixing of propellant gas and liquid and thus imperfect filling, the latter in particular as part of the liquefied form in The propellant gas entering the intake valve evaporates on the long supply path, through which the liquid enters the gas phase, there, supported by the increasing reduction of the gas aura as the container is filled, builds up a higher pressure than the state of equilibrium and thus brings the fumigation process to a standstill prematurely . in particular, with slow Begasungsverlauf can by the ^ ^r andwärme of the propellant gas-Wachfii 11behälters exceed the user of the internal pressure of the refillable container, which makes it koiiiirit of the refill container to a Hückatrömutig and thus contamination. Another disadvantage is that in the known Vorrichtu The seal of the container closure acting exclusively in the axial direction.

Becomes difficult during the closing and opening process. the The proposed attachment of key surfaces on the outer surface of the container brings about an improvement in this regard, however, requires additional tools and degrades the appearance of the container. Furthermore, the exclusively axially acting sealing elements are only effective over a short lock away, so that already The slightest opening movements lead to a leak. on Because of the various disadvantages described above, the known refillable reel containers could not find general use.

De2 · JJTl'iuduur is based on the task of creating a refillable container for the production and removal of a sprayable propellant gas -iAliiooi.-j.eits-Geiiiiöehes, while avoiding the indicated compartment parts of known arrangements while ensuring a long usability and a reliable and smooth running sealing the Eehälterver.Schlusses _c rapid and complete fumigation with simple, foolproof and Eeschädigun; sraöglichkeiten the decisive for the service life of the filling and Wntnahü.eventile "vveitestgehend exclusive handling allows the container in mass production with substantial use of commercially available components easy to manufacture and should have a pleasing visual appearance and can also be provided with extraction valves with a metering device.

Container and propellant gas source automatically opening without actuation aid and a backflow is formed by an automatic closure preventing pressure relief valve.

Due to the conical design of the filling opening of the propellant gas filling valve, there is primarily no additional sealing elements with the Plastic valve cone of the propellant filler pack against this, a reliable, tolerance-free and, within certain limits, diameter-insensitive seal is achieved.

The fact that the liquefied propellant gas in a sharp jet is entered into the liquid to be atomized from below at a high flow rate and the container is in an upright position, a faster and more complete gassing process ensured.

This process can also be favorably influenced by the fact that the liquefied propellant gas through a downstream pressure relief valve tangentially arranged bore into which the liquid flows.

The filling opening for the liquid to be atomized is through sealing elements preloaded or preloading during the closure, sealing elements acting radially or radially and axially, whereby a particularly safe and smooth closure is given.

Because within the liquid filler cap at least one relief bore between the sealing element and the screw thread is provided, the pressure of the container is reliably relieved before it is finally opened.

It is advisable to use a metering valve as the extraction valve, the dosage amount is preferably chosen between 30 and 60 mg.

The container content is between 2 and 30 ecm, mainly between 4 and 12 ecm.

A good observation of the filling process and the filling level, connected with a pleasing appearance, is achieved in that the container is made of a transparent material, primarily glass, is manufactured,

The upper part of FIG. 1 shows the refillable container according to the invention in a particularly advantageous design, while the illustration arranged below shows the Tre.ibgas refill container. The refillable container consists of the body 1, the upper, not shown opening of which is closed by the extraction valve 2 and the lower opening by the filler cap 3. In this example, the extraction valve 2 is firmly connected to the body 1 by rolling up the valve capsule made of I.letall in a known manner. The protective cap 5 covers the removal valve and the spray head 6 with the spray nozzle 7 arranged on it. The riser pipe 8, which extends to the bottom of the container, takes over the conveyance of the sprayable mixture to the extraction valve constricting body is arranged, wherein the neck opening is provided on the outside with a counter-thread 12 sum internal thread 9 of the filler cap. A sealing element is provided between the thread 9 and the extension 10. In the drawing, possible embodiments of this sealing element are shown with 13> 14, 15 and 16, arrangement 13 showing a purely radially acting seal, while the other arrangements are effective both radially and axially. It is advisable to use light elements based on natural or synthetic lastoins with properties specially tailored to the intended use. It is also advisable to make the seal on the inner wall 17 and / or the top surface 18 of the Halnöt'furig 11, since the sealing circumference is the smallest here.

recess "is flush with the head surface of the extension 10 and is permanently attached in this, for example by retaining beads 24. The actual sealing element of the propellant gas filler valve is held with the insertion surface 25 of the insert 23 and sealed to the outside under prestress. With the interior of the container the propellant gas fill valve is connected via a bore 26 or, as in FIG. 2, via a tangentially guided bore 27. The propellant gas fill valve is designed as an automatically opening and closed pressure relief valve. In Pig. 1, this is formed from a ball 29 sealing the inner bore of the sealing washer 28. However, it is also possible, omitting the sealing washer 28, to seal the bore 21 directly with a rubber ball. A very light spring support for the ball can also be recommended. A particularly advantageous embodiment of the propellant gas filler valve is shown in FIG. In this case, a molded rubber part 30 made from one piece, which is held on the collar-shaped outer edge 31 by the insert 23 and at the same time sealed from the outside, acts as the pressure relief valve. As can be seen from Figo 3, the molded part has an axial bore 32, dia sioii upwards to Lo ρ ff lä. before 33 of the molded part narrows to a slot 34. The fact that the cylindrical outer part 35 is flattened by lateral flanks 36, 3 ^ 'to the junction surface 33 h ± Y) results in a lip-shaped design of the same.

The propellant Mach filling container is available in the commercial version together from the actual can body 37 and dei ;. Self-closing valve 38, which is attached in a known manner to this with the interposition of a seal 39. Inside the valve 38 is the valve housing 40 with a pierced extension 41 and a riser pipe 42 attached to it, which is inserted into the propellant gas filling 43 immersed to the bottom of the container, firmly arranged. In the housing 40- "the ur.d, which is prestressed by means of a spring 44, is attached to the Sealing washer 45 sealing valve cone 4o guided, the one hollow Has shaft 47, in the one or more radial bores 48 flow in, with the Aui3eiiauroliinest; he of the villain ^ / in order of magnitude on the filling opening 22 d «s after filling.: ^ age is matched.

this is in: emptied, sprayed, basic state to be refilled is located.

The operator opens the filler cap 3 in the manner of a normal screw cap. As soon as the sealing torque between the Haisoffuung 11 and the sealing element 13, 14, 15 or 16 arranged inside the filler cap is canceled, the residual gas in the refillable container from the previous filling escapes through the relief bore 19. Additional threads 9, 12 are ensured that the complete opening of the container is only possible in the pressure-relieved state. In order to ensure this even when the container is filled, the relaxation bore 19 is dimensioned correspondingly large, or several stress-relieving bores are distributed over the circumference. For filling the container with the liquid to be sprayed comparable ä 49 of this is placed in inverted position, v / obei advantageously the top surface of the protective cap 5 can be used as a standing surface. The filling amount of the liquid to be sprayed is either predetermined by appropriate portion packs or is filled into the container body 1 through the neck opening 11 by the user up to a marking attached to the latter. The filler cap 3 is then placed back on the container and screwed as far as it will go. The refillable container is then placed in an upright position with the filling opening 22 on the shaft 47 of the self-closing valve 38 of the propellant gas refill pack and this is opened by pressing the two packs against each other in that the valve cone 46 is moved into the valve against the closing direction of the spring 44 and the radial bores 43 enter the interior of the housing 40 from the sealing area of the sealing washer 45. The liquefied propellant gas automatically opens the pressure relief valve of the refillable container due to its own pressure, either as in Pig, depending on the design of the container. 1 by lifting the ball from the sealing seat or as in Pig. 2 by opening the lips of the rubber mold 30, and flows directly into the liquid 49 to be gassed via the filling bore 26 or the tangent bore 27.

Filling container and within the propellant gas filler valve 20 of the refillable container to be larger than the cross section the filling hole 26, 27 itself. However, this must still be kept so large that the gassing process takes place within a few seconds has ended and thus the high inflow speed required for the intimate mixing of propellant gas and liquid given is. As soon as the pressure between the refillable container and the propellant gas refill container is equalized, it closes the "overpressure valve of the refillable container either through Sinking of the ball onto the seal seat 28 or by closure of the slot 34 of the molded rubber part 30, so that an overpressure occurring in the refillable container does not lead to a backflow can lead to the propellant refill container. After separating the two containers, the sealing of the "pressure relief valve" of the refillable The container further reinforced by the internal pressure of the same. The refillable container is ready for use after removal the contents of the protective cap 5 can be removed in sprayed form by actuating the spray head.
