Definitions

  • the present invention relates to a device and a method for automatically maintaining a constant pressure on liquid media, which device is intended for dispensing pressurized liquid or creamy products, at least containing an inner elastic container (2), a tensioning element made of macromolecular material Rubber type, a valve which is connected to the elastic container and a solid core and is comprised of the elastic container and the elastic strapping element.
  • propellant gases such as chlorofluorinated hydrocarbons or butane-propane mixtures not only serve as expulsion energy in the aerosol cans, but also when relaxing in contact with the outside air not only significantly reduce the product drops mechanically reduced by the related atomizers, but also very quickly evaporate, because every droplet also contains a certain amount of gas. Since these liquid propellants also serve as solvents, it goes without saying that the product concentrates dissolved in them actually achieve the desired effect, especially with insecticides and air fresheners. In the case of hair lacquer, perfumes, body deodorants, etc., of course, the majority of the product concentrates are lost due to premature evaporation. This can be made easily visible by spraying a surface with a commercially available paint spray. If it is a light color, you will find a finely divided layer of paint on dark objects even 2 m away from the sprayed object.
  • C02 or nitrous oxide in aerosol cans is limited only acceptable, it osenrestvolumens is proportional to a pressure loss of product output amount and the associated increase of the D, affects the qualities such as linear ejection volume constant particle size and so on.
  • the inventor of the present invention has developed an alternative for the known gas aerosol bombs, which, under the title "Device for the Dispensing of Gaseous, Liquid or Creamy Products and Processes for Their Manufacture" in German Offenlegungsschrift No. 27 47 045 of April 27, 1978.
  • This device contains an inner bag made of deformable but non-stretchable material for receiving the product and an element enveloping this bag made of macromolecular material of the rubber type.
  • a valve element for controlling the delivery quantity of the product and a product dispensing element connected.
  • the maximum filling volume of the device is determined by the dimensioning of the bag. When filled, the enveloping element is not stretched beyond the point where it leaves the linear zone of its expansion diagram.
  • the device can be provided with valves and nozzles which enable microscopic atomization of aqueous solutions under a pressure which is very low compared to the usual spray cans.
  • a core is described, the cross-sectional area of which is preferably 75% larger than that in the interior of the unclamped covering element. It is thereby achieved that the wrapping element cannot contract as far as, even after permanent deformation, it leaves the linear zone of its expansion and contraction diagram. This is of the utmost importance because the linear zone extends from approx. 30% to 45% elongation. This means that when the permanent elongation is 30%, the 75% larger core limits the contraction of the wrapping element by the percentage where - despite permanent stress and aging stretching - the stretched wrapping element is still in the linear zone.
  • H aarlack about 30% of the global aerosol market, or about 2 billion units per year, requires a particle size of about 10 microns, which must be discharged at a high speed, so that they not only fall on the hair, but also to lie in between come to guarantee an airy hairstyle through an invisible fixation. Furthermore, the hair lacquer must dry as quickly as possible to avoid streaking when pushing the hairstyle into place.
  • Insecticides and air fresheners together about 12% of W elt modes, or about 750 million units per year, requiring a particle size of about 5 microns, so that they float in the air and neither furniture nor stain walls and parquet. You must also leave the packaging at high speed to penetrate as much as possible into the room to be treated.
  • the inner bag of the device described in the DOS mentioned must be welded from a plasticized aluminum foil in order to be gas-tight and spore-tight, the material being as thin, ie as flexible as possible must be possible in order to provide the wrapping element with as little mechanical resistance as possible.
  • the spray nozzle described in patent application no. 2024 / 78-6 is able to compensate for certain pressure losses in such a way that the particle size remains small enough, but it cannot prevent a reduction in the second ejection rate and that the ejection speed decreases, But what is not acceptable for hair lacquers, various medications, insecticides and air fresheners and, of course, depending on customer taste, also for the products to be sprayed described above.
  • the quickly evaporating products such as hair varnishes, insecticides, air fresheners, leather care products, ski waxes, shoe creams etc. demand as a solvent e.g. Methylene chloride, trichlorethylene, 1, 1, 1, trichloroethane, which additionally have the advantage of being non-flammable, but which must be stored in containers which are resistant to these solvents.
  • a solvent e.g. Methylene chloride, trichlorethylene, 1, 1, 1, trichloroethane, which additionally have the advantage of being non-flammable, but which must be stored in containers which are resistant to these solvents.
  • the bag described in the aforementioned patent applications has a polyethylene or polypropylene film as the inner covering. However, the abovementioned solvents migrate through these foils and dissolve the adhesive that connects them to the polyester or aluminum foil. This dissolving of the adhesive would still be acceptable if there were no delamination behind the weld seams, which then makes the bag leak.
  • the aluminum bag described in the aforementioned patent applications is comprised of a pleated composite film which is welded to the side lengths, so that the e- g fold point becomes the bottom of the bag. This has to be because, due to the open wrapping element spanning the bag bottom, the bag contents come into contact with the atmospheric pressure, as a result of which the thrust resulting from the wrapping element squeezing pressure fully affects the bag bottom, which relieves the side weld seams. If the bag bottom had been welded, this weld seam would tear, as tests have shown. In the embodiment described, however, the bag bottom bulges in the direction of the valve and thus in the direction of the core. Therefore, the core must be considerably shorter, approx.
  • a shorter core means product loss due to the product remaining in the part of the bag that is not around the core and leads to a loss of pressure when the device is nearing final emptying, since the core missing in this part does not hinder the wrapping element can get into the zone where there is no linear pressure.
  • the resistance to stretch which the open end of the sheathing element emits is less than that at the level of its attachment to the valve. This means that when the bag is filled, it first expands at the bottom of the bag, than where the resistance of the wrapping element is at its lowest, which leads to the aforementioned curvature of the bottom of the bag.
  • the dimensioning of an aforementioned device is determined by the outer diameter of the commercially available aerosol cans and held so that it does not disturb the habits of the consumer, especially as regards the handiness of erosoldosen A.
  • An example is a commercially available format, in which the outer diameter of the can is 50 mm and the inner diameter, depending on the wall thickness, e.g. Is 48 mm.
  • a wrapping element which has an inside diameter of 46 mm at 450% elongation, has an inside diameter of untensioned, unused If you want to give it a pre-tension of 75% using the core, the outer diameter of the core must be be.
  • the aforementioned device takes on either a conical-oval or ovoid-oval shape thanks to the shape of the aluminum bag, both of which lead to a substantial lengthening of the wrapping element.
  • An outer container containing the aforementioned device cannot be precisely adapted to the aforementioned device for aesthetic or technical reasons.
  • an outer container must offer enough space to accommodate the extension part of the wrapping element that results from the filling process, unless it is cut off.
  • this is not only uneconomical because of the additional work that arises as a result, but when the device is emptied it can happen that when the wrapping element is shortened, the cut-off part is missing and the aluminum bag escapes from the wrapping element.
  • the extended wrapping element therefore requires a longer outer container, which causes a lost volume that is not filled with product.
  • the loss of tension after 12 months of storage under an expansion of the wrapping element of 225% is only 19%, which means that immediately after filling, an ejection pressure of 3 bar and on the 365th day of 2.3 - 2.5 bar is measured.
  • Differences in the measurements result from the high tolerances that apply to rubber, because multiple factors such as rubber mixture, filling material, accelerator, type of vulcanization, vulcanization time, heat of vulcanization play a role in quality, among other things.
  • measurement fluctuations result from the atmospheric external pressure if the measurements are not carried out under identical conditions.
  • the ambient temperature during storage also influences the aging process of the rubber. So you may switch M essunter Kunststoffe of + 15% fixed.
  • the present invention is therefore the object of the disadvantages of the known device for dispensing gaseous liquid-described and other, I sigen or creamy products by means of a device for automatically maintaining a constant pressure acting on liquid media to overcome und.eine Vorrich tion that can be used for the majority of products stored in gas aerosol cans.
  • the invention is intended to include a method that serves the same purpose and include a manufacturing method for the device.
  • this object is achieved on the one hand by a device which is characterized in that the elastic container is made of rubber, which is resistant to the respective product stored therein, that the tensioning element is made of natural rubber, that the inside diameter of the elastic container is before it is attached the core corresponds to the outer diameter of the same, that the inner diameter of the elastic clamping element in the untensioned state is at least 20% smaller than the outer diameter of the core plus the wall thickness of the elastic container attached to it, but is not more than 25% smaller, and that core, elastic container and elastic tensioning element are firmly and sealingly connected to one another in the region of the two core ends.
  • the present invention takes advantage of this physical law and creates the basis for creating a device which ensures good imitation of the aerosol cans operated with propellant gas without propellant gas.
  • solvents such as methylene chloride, etc. migrate through the polyethylene or polypropylene coating of the aluminum bag and result in the described leakage.
  • This can be avoided by making the inner layer of the aluminum bag from nylon, which, however, no longer requires pure heat but high frequency welding.
  • nylon is expensive and, with a sufficient thickness, offers the sheathing element a higher mechanical resistance than e.g. Polyethylene.
  • Such a bag must of course also be preformed as described in order to avoid bursting when filling.
  • the aluminum bag not only because it is larger than the rubber bag, also takes on an identical shape to that of the seamless rubber bag when it is folded, also due to the shape of the welding technique, so that the wall of the aluminum bag, however, only on everyone Contact points, is exposed to a constant thrust, so there can be no bursting of the aluminum bag due to highly compressed air.
  • the filling product C02, N20 or N2 is admixed which, in addition to the intended final gasification in the event of a loss of rubber pressure, also temporarily when the device according to the invention is stored at higher temperatures, e.g. 50 ° C, can become gaseous and if this gas bubble does not hit an expandable, but flexible but inextensible wall, as would be the case with the aluminum bag alone, it could burst.
  • the linear force release zone of the described rubber of the wrapping element is between an elongation of 30-450%. It is found that the smaller the inside diameter of the unclamped covering element, the higher the start of the linear force delivery zone. With an inner diameter of 8 mm, this zone begins on the day of filling after an elongation of approx. 30% and with an inner diameter of 14 mm after an elongation of 18%. This is difficult to calculate mathematically, but it looks as if the percentage halves when the inside diameter doubles in the untensioned state, the percentage divides three times with an inside diameter three times larger, and quarter with an inside diameter four times larger.
  • the outer diameter of the outer core which gives the encasing element a prestress, must total approx. 30% (12.3 + 18 %) be larger than the inner diameter of the unclamped sheathing element if one wants to achieve that the sheathing element is already hampered by the core in the contraction when it is still in the linear force delivery zone, which is an outer diameter of an outer core of 18.3 mm represents.
  • the core represents approximately 10% of the filling volume, the device taking on such a shape that there is too much lost volume in an outer container.
  • the core diameter of 18.3 mm now allows the expansion of the wrapping element to be limited to 225% with a product column diameter of 46 mm, thus reducing its tension loss from 70% to approx. 18% and its permanent enlargement from 30% to 12.3% .
  • the device according to the invention In order to comply with the regulations which allow 30% lost volume in a pressure vessel, the device according to the invention must be designed in such a way that it takes on such a form that the lost volume in an outer vessel is at most 13.7%.
  • the device according to the invention shows a device according to the invention, which is created in such a way that the outer container containing it has less than 10% (8.7) of lost volume.
  • the device according to the invention consists of a core 1, a rubber bag 2, an aluminum bag 3, a wrapping element 4, a valve element 5, a product delivery element (not shown), a core base sleeve 6 and an outer container 7.
  • the core 1 is at the upper end 8 with an annular rib 9 , a seal seat 10 and annular grooves 11 and 12 and has a chamber 13 which serves to receive the valve element 5.
  • the bottom of the chamber 13 is provided with bores 14 and 15 which are connected to a transverse channel 16.
  • a pin 17 protrudes axially from the bottom.
  • the core 1 is provided on the outside with a plurality of channels 18, through which the product 19 can flow to the transverse channel 16 when part of the rubber bag 2 is already firmly against the core.
  • the lower end 20 of the core 1 is open and shows an annular groove 21.
  • the core 1 is made of a solvent-resistant plastic material, for example polyamide 66, and is hollow on the inside. Its outer diameter is kept so large that the volume of the core 1 is more than 15% compared to the filling volume if the device according to the invention is stored in an outer container, the filling volume of which is taken into account in the aforementioned regulations.
  • the core 1 is preferably coated with the rubber bag 2 in the immersion process. This can consist of several layers, which is why the immersion process must be given priority.
  • the rubber bag 2 must be made of Viton, epychloride, butyl, nitrile, neoprene, Bfuna or silicone.
  • the outer layers of the rubber bag 2 made of natural rubber should be of great purity, because this has the greatest permanent elasticity and therefore the smallest permanent enlargement is the result of long-term storage in a stretched, filled state.
  • This permanent enlargement remains very small with the rubber bag anyway, approx. 12% after 24 months, because its elongation is only 150% with a product column diameter of 46 mm, since its diameter is approx. 18.3 mm when unstressed.
  • the product 19 is therefore in contact with the inner layer of the rubber bag 2 and not with the polyethylene or polypropylene layer of the aluminum bag 3. This prevents migration of the product solvent and there is no delamination of the aluminum bag 3. As shown in FIG.
  • this consists of several layers, for example an inner layer made of polyethylene, then polyester, then aluminum and outside again polyester, the polyester layer between aluminum and polyethylene layer avoiding the scissor effect of aluminum.

In the closed state, the transverse channel 27 is sealed by the sealing washer 24 thanks to the compression spring 25. If one presses on the piston 23 by means of the product delivery element (not shown), the transverse channel 27 comes to lie below the seal 24 and the product 19 is expelled by the pressure of the rubber bag 2 and the wrapping element 4 via the axial channel 26 and the output element, not shown, whereby the cone 23a of the piston 23 prevents product leakage along the piston 23 by pressing on the sealing washer 24.

  • the 225% curve shows that the squeeze pressure drops rapidly and begins to stabilize after 10 days and has stabilized after 30 days so that the subsequent pressure drop due to long-term storage is relatively small compared to the pressure losses of the first 10 days.
  • Fig. 12 shows that due to the reduction in residual volume after product ejection, there is no .. ejection pressure reduction.
  • a strong drop in the pressure of the rubber counter pressure is found during each discharge, but this is brought back to the pressure value before the discharge by a recovery of the rubber wrapping element, of course minus a percentage which is approx. 10% between the full and completely empty product container.
  • Two factors, not shown here, help to compensate for this temporary pressure drop, on the one hand the practically constant surface of the product level which acts on the C02 pressure which remains constant due to the volume reduction and on the other hand the spray nozzle described in patent application 2024/78, which can compensate for pressure drops, so that the spray behavior does not change significantly.
  • FIG. 13 shows a section through a device according to the invention on the filling day, on which the rubber back pressure of the wrapping element 4 is greater than the CO 2 pressure, so that it cannot gasify and remains completely dissolved in the product 19.
  • FIG. 14 illustrates a device according to the invention after storage for approx. 30 days, during which the rubber counterpressure of the wrapping element 4 has decreased so that part of the dissolved CO 2 can gasify until the C02 pressure together with the remaining rubber back pressure has reached the pressure value which forces the C02 remaining in the product 19 to remain dissolved therein.
  • FIG. 15 illustrates that when the product container is emptied, the wrapping element 4 first contracts at the valve 23, as a result of which its wall thickness becomes thicker and thus helps to press the CO 2 bubble 41 against the product level 42, that is to say reduces the remaining volume of the product container continuously proportional to the output of product 19.
  • the device according to the invention of Fig. 16 fulfills these requirements. It shows a section through a device according to the invention for dispensing two different media, both of which can either be liquid or creamy, or one can be liquid and one creamy, or one of the media can be gaseous.
  • the core 1, essentially identical to that of FIG.
  • a further seat 62a which serves to receive a sealing washer 63.
  • This is pressed onto the seat 62a by means of a clamping ring 64, which is firmly connected to the upper core end 8 thanks to a snap lock 65.
  • the clamping ring 64 is provided with multiple openings 66, the number of which is so large that min at least one comes to lie in front of an opening of the transverse channel 16.
  • the piston 67 is provided with a longitudinal channel 68, which opens into a longitudinal channel 69, which can optionally be smaller, larger or identical in diameter to that of the longitudinal channel 68. Before the mouth of the longitudinal channel 68 is a transverse channel 70, which is closed with the sealing washer 24.
  • the longitudinal channel 69 opens into a transverse channel 71, which is sealed by a sealing washer 63.
  • the piston 67 is expanded into a flat plate which, thanks to a compression spring 73, which is supported on the clamping ring 64, is pressed firmly against the sealing washer 24 and thus closes the upper valve stage.
  • the lower valve stage is also closed because the piston 67 is provided with a barb 76 which, thanks to the compression spring 73, is pulled against the sealing disk 63, so that the transverse channel 71 is covered by it and thus closed.
  • the cone 74 of the sealing disk 63 leaves sufficient scope to allow it to bulge upwards under the pressure of the medium 77, which is located in the rubber bladder 78, and thus firmly against the seat 75 of the piston 63 to create.
  • the rubber bladder 78 mentioned is preferably molded onto the sealing disk 63, assuming the shape 79 in the empty state. Such a rubber bladder 78 is only required if the medium stored therein has to be ejected with practically constant pressure, which, as already described, is the case thanks to the rubber. If a rubber bladder 78 is used, the base sleeve 6 must be provided with an opening 80 which prevents overpressure when filling and the creation of a vacuum inside the core 1 when emptying.
  • FIG. 17 shows a device according to the invention which, apart from the missing rubber bladder 78, is identical to the device of FIG. 16, whereby the possibilities of the valve arrangement described also apply here.
  • This embodiment of the invention can also contain known liquid propellants.
  • the cavity 20 of the core 1 contains the liquid propellant gas 81 with a gas phase 82.
  • the cavity 20 is, as in FIG. 6 shown, provided with a reinforcement partition 62 which has the cutout 83 to allow the piston 67 to move axially.
  • the ground sleeve 6 serves as a hermetic, pressure-proof closure of the cavity 20.
  • the same embodiment can be used if you want to store a gas medium in the cavity 20 that does not have to be expelled at constant pressure, using C02, N2 or N20 or can only use air. The functioning of the double-stage valve is explained with reference to FIGS. 20, 21 and 22.
  • FIG. 18 shows a valve element according to FIGS. 1 and 2 in the closed state and FIG. 19 shows the same valve element in the open state.
  • FIGS. 16 and 17 illustrates a closed valve element according to FIGS. 16 and 17.
  • stage A opens first and gas 82 can already escape while upper valve stage B is still closed.
  • This arrangement has the advantage that when closing the process takes place in reverse, that is, stage B closes first and only afterwards stage A.
  • FIG. 22 shows the valve element of FIGS. 20 and 21 fully open, so that both media, as described with reference to FIG. 14, are expelled and mix in the longitudinal channel 68.
  • the compression spring of a valve element can be held much stronger, which on the one hand guarantees an instantaneous closure of the valve element in the presence of a low ejection pressure and on the other hand is so strong that a child's hand cannot generate the force , which is necessary for opening a valve element, quite apart from the fact that the dimensioning of the device can already be held in such a way that a child's hand cannot encompass it and can also press it.
  • the outer container 7 is provided along a neck 84 with walls 85, in which semicircular notches 86 serve as hinge seats.

  • the device is mounted in a closure cap 94 which holds it together and prevents the movable pressure walls 87 and 88 from moving in the wrong direction.
  • the closure cap is provided with the openings 95 and 96, which allow lateral pressure to be exerted on the pressure walls 87 and 88, as indicated by the arrows 97 and 98. This results in a rotary movement of the pressure walls 87 and 88 at the level of the hinges 86, so that their bars 91 and 92 with the oblique sides 91a and 92a press on the dispensing element 93 in such a way that it moves in the direction of the arrow 99, which opens the Valve element leads.
  • a decrease in the pressure on the pressure walls 87 and 88 has the consequence that a strong compression spring of a valve element described raises the output element 93 upwards and the pressure walls 87 and 88 into it Pushes the starting position back, which also closes the valve element.
  • the output element 93 can optionally be provided with a spray nozzle or a jet nozzle.

  • the oblique sides of the pressure beams 112 and 113 exert pressure on the plate 101, as a result of which the piston 100 is moved downward and opens a described valve element.
  • the emerging product expands the Squeeze point 115 of hose 102 and it can escape through opening 116. If the pressure on the clamping jaws 103 and 104 decreases, the spring 109 compresses them again, the plate 101 is released and the gripping jaws 110 and 111 squeeze the hose together again at level 115 and close it frontally.
  • the treatment of plants requires the use of plant care and protection agents, which can be highly toxic in concentrated form and must therefore be used diluted.
