c Id: 3779060 1 SPRAYING CONTAINER BACKGROUND OF INVENTION The invention relates to the packing technique field and can be used, e.g. in spray cans applied for the varnish and paint, perfumery industry, fire technique and in the everyday life for spraying of household chemical goods and drink aeration. The known spray container consists of the body, dispensing valve, which is placed in the opening on the body side, a liquid to be sprayed, propellant, a propellant sorbed by a sorbent material, placed inside the body (International Application PCT/RU92/00129, filed: 26.06.92; Priority Date 29.06.91; International Publication Number WO 93/00277, Date: 07.01.93, International Classification 5 B 65 D 83/14). The charging of this spray container is accomplished by means of the charging valve for sorbent substance and propellant and by the dispensing valve, which permits the high grade of packing charging by the liquid to be dispensed and high charging quality. With that the known device requires providing more time for charging the spray container, and it requires providing automatic rotor systems for charging of such containers which would provide the required sorbent and a propellant liquid filling taking into account time needed for the sorbent material processes inside the can. There is also known the spray container, which includes the body, the dispensing valve, installed in the opening of the body wall, the liquid to be dispensed, propellant, capsule, which are placed inside the body, sorbent substance particles saturated with propellant gas and placed inside the capsule, and the filter element, which serves as a capsule body cover. The device is permeable for propellant gas because of the openings in the gas-proof material and has sorbent particle retention properties (United States Patent No. 3964649).

c Id: 3779060 2 This device is relatively simple, since the spray container can be charged with the dispensing liquid and capsule through the opening (orifice) in the body wall before the installation of the dispensing valve. This method can worsen the quality of the sorbent substance saturation by propellant gas because the materials, which have higher absorption heat in sorbent substance than the propellant, can penetrate the sorbent substance. Besides, the operation of the pressurized dispensing container and the capsule filling because of the deformation and the capsule cover gas detaining are difficult from the point of view of the processes automatization. This is firstly stipulated by the charging lines and gating devices creation hermetization necessity, since the filter element, which is penetrating for a propellant gas and is capable for the sorbing particles detaining, is made as the hydrophobic capsule cover. There is known a capsule for gas storage, which (capsule) contains a gas impermeable body inside which the particles of a sorbent material saturated with a gas are placed, and which is supplied with an outlet sealed channel. The capsule body contains free from a sorbent material space, the volume of which is enough for the sorbed gas given quantity in solidified phase, and made with the possibility of introducing inside the cover of the sorbed gas in a solidified phase. As a sorbed gas it is considered the possibility of the CO 2 usage, and as a sorbent material - adsorbent carbon (Patent RU 2171765 Publication Date August 10, 2001, International Classification 5 B 65 D 83/14). In this device there appears a danger of recompression (the creation of non-permitted high pressure) in case of the capsule placement, charged with CO 2 in a solidified phase ("dry ice"), in the spray container, e.g. in plastic-made spray container, which has limits in solidity, as the CO 2 evaporation and this gas outcome in the spray can at insufficient by the sorbed dynamics absorbent carbon characteristics will create high pressure inside the can for a short period of time, what causes a danger of its damage. Reference to any prior art in the specification is not, and should not be taken as, an acknowledgment or any form of suggestion that this prior art forms part of the common general knowledge in Australia or any other jurisdiction or that this prior art could reasonably be expected to be ascertained, understood and regarded as relevant by a person skilled in the art. SUMMARY OF THE INVENTION c Id: 3779060 3 The task, being solved by the invention, consists in the choice of material and constructive technical decisions, allowing to heighten the process safety of the pressure creation in the spray container and at its work to improve the spraying characteristics at the spraying liquid evacuation. The technical result, which can be received at the invention realization, is in the risk decreasing of the spray container damage and the provision of more homogeneous pressure at spaying of the liquid to be dispensed.

The granulated porous carbon matrix can be capable of adsorbing under a pressure between 0.3 MPa and 0.6 MPa at a temperature of -10*C at least 0.75 mmol of carbon dioxide per I g of the adsorbent carbon upon a pressure increase of 0.1 MPa. The adsorbent carbon can be made by chemical or steam-gaseous activation of peat or coconut peel. The adsorbent carbon may contain carbon matrix the surface of mesopores of which with a size between 1.5 and 200 nm can be at least 50 m 2 /g. The adsorbent carbon can be made with carbon matrix of the pore volume of which can be between 0.5 and 1.2 cm 3 /g and wherein a pore surface in the carbon matrix is at least 500 m 2 /g. The adsorbent carbon mass can be between I and 10% of a mass of the spray liquid. The outlet valve can be placed in a lower part of the capsule. The capsule can be made of a material with low thermal conductivity. The posed task was accomplished with successful technical result by application of the above indicated spray container, comprising a body comprising: a dispensing valve in an opening in a wall of the body; a spray liquid inside the body; carbon dioxide inside the body; a gas-proof capsule inside the body, the gas-proof capsule comprising a release valve and being chargeable with solid cId: 3779060 4 carbon dioxide; adsorbent carbon particles saturated with carbon dioxide inside the gas-proof capsule, adsorbent carbon of which contains a granulated porous carbon matrix capable of adsorbing under a pressure between 0.3 MPa and 0.6 MPa at a temperature of 20'C not less than 0.5 mmol of carbon dioxide per 1 g of the absorbent carbon upon a pressure increase of 0.1 MPa.

DETAILED DESCRIPTION The spray container (FIG. 1) consists of a dispensing valve 1, placed in the opening of the body wall 2, liquid to be dispensed 3, gaseous CO 2 (it isn't shown in FIG. 1), siphon pipe 4, capsule 5, inside which the sorbent - absorbent carbon particles are placed, saturated with CO.sub.2, and also the outlet valve 7 for the capsule gas outlet, the blisters 6 of which make liquid 3 gaseous. According to the invention capsule 5 is made from a gas proof material, and it is supplied with the outlet valve 7.

c Id: 3779060 5 In the FIG. I one can also see the siphon pipe 4 for the supply of the liquid 3 to be dispensed to the dispensing valve 1, and also situated above the liquid 3 level a free space in the body 2, the so-called "gas cushion". The dispensing liquid 3 and capsule 5 can be placed inside the body 2 through the opening, being settled for the dispensing valve 2, which can be made with the usage of any hermetic connection: demountable or one-piece, allowing to make dismantling and to open the body 2, for instance, for the change of the liquid 3 to be dispensed, the dispensing valve I and capsule 5, that helps to achieve high technology and construction maintainability. In case of the body 2 usage, made, for example, as a metal cylinder cover with rolled bottoms one can place the capsule 5 inside the body 2 also through one of the bottoms during the body 2 assembling, but before this bottom rolling with the cylinder cover. Such method of the capsules 5 placement inside the spray container, being industrially produced, allows to use as the capsule 5 cover the existing standard constructions of small displacement spray cans, the external diameter of which, as a rule, is more than a diameter of a settled opening for the dispensing valve 1. By the usage of the plastic body 1, made, for instance, from polyethilentereftalat (PET) is similar to the bottles for effervescent beverages: the dispensing valve 1 can be placed in the body 2 with the help of rotating screw fuse making hermetic thread connection with the body 2. As substantial outlet valve 7constructions one can use any known valves constructions, allowing to provide the capsules 5 filling outside the body 2. By means of capsulation the capsules 5 provision through the outlet valve 7 they manage to provide the constancy of the dispensed liquid 3 composition and high dispersion quality, and also to minimize the sorbent - absorbent carbon quantity in the capsule 5. The reduction of the sorbent quantity in the capsule 5 allows to raise the degree of fullness of the body 2 of the spray container by the dispensed liquid 3. Besides, it is possible to re-use the body 2, of the capsule 5 with different dispensed liquids 3. The critical dimensions of the capsules 5 are chosen from the provision of the possibility of their placement inside the body (FIG.1), and the capsule 5 cover material should have compatibility with the liquid 3, have low thermal conductivity for the reduction of the mutual thermal influence of the processes inside the capsule 5 and in the liquid 3. Such material should have low price and high c Id: 3779060 6 manufacturing technology, and acceptable qualities have polyethylene, polypropylene and other plastics with high plasticity. For the filling of the capsule 5 by carbon dioxide (CO 2 ) outside the body 2 of the pressurized dispensing container it is necessary to place inside the capsule 5 solidified carbon dioxide (CO 2 ), the so-called "dry ice", as granules or tablets, and then granulose absorbent carbon, after what on the capsule they mount the outlet valve 7 and place in the body 2 till the mounting on it of the dispensed valve 1. For sparging improvement (at occurring inside the capsule 5 evaporation of "dry ice") of the blisters 6 of carbon dioxides of the liquid 3 the outlet valve 7 should be placed in the bottom of the capsule 5 to increase the depth of the mass-changing processes beginning between the liquid 3 and the blisters 6 of carbon dioxides, increasing thus the degree of saturation of the liquid 3 by gas, and, hence, - the dispensing quality. At the same time, the construction, represented in FIG. 1, allows to supply reliable gas feeding from the capsule 5 inside the body I and simplified and relieved from work complexity with high pressure the filling process of the pressurized dispensing container. The filling by the dispensed liquid 3 and by the capsules 5 of the bodies 2 of the spray container can be realized by means of throwing on the rotor lines of the capsules 5 inside the bodies 2, due to what the time of the pressurized dispensing containers filling by beforehand filled capsules 5 by carbon dioxides is reduced. At realization of the construction stated variant and formation of the filled spray container it is important to provide technological restrictions, caused by the limits of safe workability of the device elements and, first of all, allowable gas pressure inside the body 2. The matter is that carbon dioxide amount, placed as "dry ice" in the capsule 5 at its filling, is chosen by sufficient for the required pressure creation in the body 2 and appropriate required saturation of the liquid 3 by gas. Being inside the capsule 5, absorbent carbon also absorbs the evaporating gas and serves as its storehouse for the gas losses compensation at evacuation (dispersion) of the liquid 3. The curves of adsorption of carbon dioxide by adsorbent carbon at temperature 20 0 C are represented at the experimentally obtained graphics FIG. 2 and 3. In FIG. 2 and 3 it is evident that at propagation of its pressure the saturation gas speed varies (curve 1) in different ranges. The pressure in the graphics FIG. 2-7 is given in atmospheres (I atm. is approximately equal to 0.1 MPa). Usually used for adsorption CO 2 adsorbent carbon such as BAU (raw material - beech) demonstrates smaller c Id: 3779060 7 saturating speeds (FIG. 3), than adsorbent carbon, containing according to the invention a granulose porous matrix, adsorbing not less than 0.5 ml of carbon dioxide per I g of adsorbent carbon at carbon dioxide increasing of pressure per 0.1 MPa in its pressures range from 0.3 to 0.6 MPa at a temperature 20 0 C (FIG. 2). There exists minimally acceptable value of saturating speed, being determined by necessary gas storage in a sorbent material, on the one hand, and admissible pressure boost at a system yield "gas - sorbent - liquid - gas cushion" on equilibrium during the filling process. Calculations and experiments with the pressurized dispensing containers and capsules, filled by sorbent - absorbent carbon and carbon dioxide in a solidified phase, defined the lowest admissible limit of adsorbent carbon sorption properties , which makes not less 0.5 ml of carbon dioxide per 1 g of adsorbent carbon at carbon dioxide pressure increase on 0.1 MPa in its pressures range from 0.3 to 0.6 MPa at temperature 20 0 C to provide a safe level of the pressure initial running out at its creation and effective compensating gas feeding from the capsule at liquid evacuation. For providing of high quality of the liquid 3 dispensing and safety maintenance of the spray container the mass share of sorbent - absorbent carbon - should make from I to 10% of the dispensing liquid 3 mass. The low limit is determined by the gas storage effect beginning in a sorbent material on the dispensing quality. At a sorbent material making according to the invention at characteristic for spray container pressures level 0.3-0.6 MPa the gas share, being stored in a sorbent material, can make in relation to gas, being sorbed in the liquid from 10 to 100% where the smaller numbers are characteristic for the well sorbing CO 2 liquids like acetone, and larger - for alcohol and water containing compositions. In case of less than 1% of a mass share for aqueous compositions sorbent will give not less than 10% of common pressure creating gas, what practically will have no effect on the dispensing quality, so the direct saturation by gas of water based liquid 3 will give practically the same result without the usage of technical solutions according to the invention. In case of more than 10% of the mass share of the further improvement of the dispensing quality will practically take no place, as the pressure decreasing in the liquid 3 evacuation process will not exceed 20-30%, that will not have any efficient effect on the dispensing patterns, submitting dependence 1 p, where p is the liquid pressure on the section of the dispensing valve 1 injector. As the experiments have shown usually the adsorbent carbon mass share, which is 3-4%, is enough for the required improvement of the liquid 3 dispensing quality through the dispensing valve 1.

cid: 3779060 8 At the speed of adsorption of CO 2 in adsorbent carbon less than 0.5 ml of carbon dioxide per Ig of adsorbent carbon at carbon dioxide pressure increase on 0.1 MPa in the range of its pressures from 0.3 to 0.6 MPa at a temperature of 20C, as the experimental researches have shown, the outcome of the evaporated "dry ice" from the capsule 5, placed in the body 2,through the outlet valve 7 will exceed the speed of saturation (absorption) of CO 2 in the liquid 3 so that in "the gas cushion" the pressure will explicate which will exceed an admissible one for spray cans (which is as a rule 1.5 MPa). As during "dry ice" evaporation (sublimation) inside the capsule 5 there is an intensive enough heat taking from adsorbent carbon, in which the sorption warmth precipitates out, the effective sorbent temperature in the first period of the process (hundreds of seconds) is kept on the low level (from -30'C to 0'C) at the characteristic value -10C (263 K), that allows to realize an exuberant in relation to equilibrium sorption of CO 2 in adsorbent carbon with the speed, which, as the experiments have shown (curve 1, FIG. 4) exceeds approximately on 50% the level of values for a room temperature, that is it makes not less than 0.75 ml per 1 g on 0.1 MPa pressure increase at a temperature of -10'C. Thus for sorbent - adsorbent carbon, made according to the invention, it is also possible to realize the technologically required sign, providing the lowering of gas losses in the interval between the placing in the capsule 5 of the given quality of CO 2 in a solidified phase and the capsule 5 placement in the hermetically enclosed body 2. Besides, the low temperature sorption with the features according to the invention allows to slow down the gas outcome from the capsule 5 in the process of gas blisters saturation of the liquid 3, that reduces the level of nonequilibrium recompressing of the body 2 in the process of the system yield on the balance. Such properties to the device are created at absorbent carbon making from raw material on the basis of peat or of coconut peel, being through chemical or steam-gaseous activation. The most effective characteristics are realized at carbon matrix making, the pores volume of which makes from 0.5 to 1.2 cm 3 /g with specific pores surface not less than 500 m 2 /g. The achievement of high characteristics on adsorption - desorption dynamic is determined by the mesopores parameters with the sizes from 1.5 to 200 nm, that is commensurable with the sizes of molecules of CO 2 , but noticeably exceeding them. The obtained empirical dependence of adsorption dynamics from the mesopores surface in carbon matrix has shown that the high required efficiency is achieved at mesopores surface, which exceeds 50 m 2 /g.

cId: 3779060 9 The carbon matrix characteristics, contained in absorbent carbon, placed in the capsule 5, determined the pressure boost at matrix heat up to marginal temperatures, as a rule being for spray cans 50-55C. As is evident from the experiments, represented on the graphics (curve I of the sorbed gas mass changing, FIG. 5 and FIG. 6), the equilibrium on adsorption of the stationary technological level at a room temperature is achieved in case of heat up to 50"C only at essential pressure increase. Thus, for carbons which don't have attributes according to the invention, (like BAU), the pressure boost (more than 1.8 MPa) exceeds an admissible one (1.5 MPa), that can cause the body 2 damage. For the device, which contains according to the invention, adsorbent carbon with carbon matrix, possessing the signs stated above, the pressure boost doesn't exceed 1.3 MPa, that provides the required maintenance safety. The application of the capsule cover materials with low thermal conductivity provides smoothing of the dynamics of the thermal processes of energy interchanging between the capsule components (sorbent - absorbent carbon and "dry ice" - non-liquid phase CO 2 ), on the one hand, and between liquid and capsule on the other hand, that, in its turn, diminishes peak levels of the pressure boost in the initial period (at the initial pressure creation) and at the increase of temperature environment, enclosing the spray container. Thus, the required maintenance safety is achieved. It is also necessary to notice, that the placement of the outlet valve 7 in the capsule bottom also allows to reduce peak levels of the pressure boost in non-stationary working regimes of the spray container due to the improvement of the mass changes processes of the gas blisters 6, coming out of the capsule, with the liquid, absorbing gas - carbon dioxide by virtue of the sorption properties, that, in its turn, allows to reduce the intrinsic gas pressure in the "gas cushion" above the liquid 3 level in the body 2, also to sate sorbent - absorbent carbon by carbon dioxide simultaneously with the dispensed liquid, and, thus, even more simplify the filling process and increase consumer qualities of the pressurized dispensing containers. The pressurized dispensing container works in the following way. At the placement of the filled both by sorbent and "dry ice" and squeezed by the outlet valve 7 of the capsule 5 inside the body 2 through wrunging out by the exuberant intrinsic pressure of gas CO 2 the outlet valve 7 gas comes out of the capsule 5. By the dispensing valve 1 hermetization in the opening on the body wall 2 with the help of coming in the body 2 volume gas blisters 6 inside the body 2 they create an excessive pressure. Under this pressure influence the dispensed liquid 3 in the cId: 3779060 10 tube 4 is given on the dispensed valve I and at its opening it is dispensed in the environment outside the body 2. Depending on the outlet valve 7 selected construction it is possible to provide high speed and degree of sorbent 6 filling by gas CO 2 and, hence, to raise the degree of the spray container filling with the dispensed liquid 3, as due to the installation of the outlet valve 7 on the capsule 5 and the insulating capsule cover, made from the material with low thermal conductivity, carbon dioxide has no time to sublimate noticeably, as both it and sorbent - adsorbent carbon outside the body 2 practically don't interact with the environment. At the liquid 3 evacuation the pressure inside the body 2 is falling (FIG. 7). For the pressurized dispensing container with the initial volume of the "gas cushion" being equal to 20% of the full internal volume of the body 2 at the usage of water as the dispensing liquid 3 and of CO 2 as gas the dispensing quality will be determined, first of all, by the speed of the gas pressure lowering inside the body 2 and by the degree of the liquid 3 gas saturation. According to the invention for pressure retention in the body 2 in the process of liquid evacuation they use some components: the pressure of the "gas cushion", gas desorption from the gas saturated liquid 3 and gas desorption from absorbent carbon, being in the capsule 5. On the FIG. 7 for the illustration of the role of each of these components and for comparison of the engineering decision, offered in the invention, with analogs they give the alternative variants characteristics. So, in particular, in case of the pressure creation in the body 2 only due to the "gas cushion" (the so-called variant "bag-in-can"), in what way it is realized, e.g. in the device, described in the US Patent 3,869,070, Publication Date March 4, 1975; International Classification 222/193, where liquid 3 and gas, making pressure in the body 2, are separated from each other by gas proof over, the pressure in the body submits to the law PV=RT, where P is gas pressure, V is its volume, T is gas temperature, R is universal gas constant value, that cause the fact that in the expanding "gas cushion" at the absence of the liquid saturation by gas the pressure will fall back proportionally to the gas expanding volume (curve 1, FIG. 7). Taking into account the absence of the dissolved in the liquid 3 gas, "blowing up" a drop of the liquid after its outcome from the dispensing valve I in the environment, the dispensing quality in such a variant will be quite unsatisfactory, and the construction of such a pressurized dispensing container and its filling by gas and liquid 3 will become more expensive. One can achieve some improvements of the dispensing quality in the existing level of technique, having achieved at the filling the complete saturation of the liquid 3 by gas at the initial pressure (curve 2, FIG. 7), that will require, however, c Id: 3779060 11 diminishing of the filling line productivity and aggravation of the working conditions in connection with sharp noise effect, caused by leaps of gas amplification at the attachment - detachment of the high pressure receiver with the pressurized dispensing container. An additional usage of sorbent, suggested according to the invention, made as absorbent carbon, containing a granulose porous carbon matrix, absorbing not less than 0.5 ml of carbon dioxide per I g of adsorbent carbon at the pressure increase on 0.1 MPa at the range of its pressures from 0.3 to 0.6 MPa at a room temperature allows with the necessary efficiency to compensate pressure fall (curve 3, FIG. 7). The matter is that adsorbent carbon, made and placed inside the body 2 in the capsule 5 according to the invention in its sorbing power exceeds absorpting capacity of water not less than in 13-15 times and, unlike the liquid 3, isn't being lost from the body 2 in the evacuation process, keeping during the whole working process its sorbing potential for gas pressure retention, that provide eventually high dispensing quality and the safety of the pressurized dispensing container filling and maintenance. Without any dependence from the outlet valve 7 selected substantial constructions for the solution of the task set with the achievement of the technical result it is necessary and enough to realize the described above filling process and sorbent making with the contents of the granulose porous carbon matrix, absorbing carbon dioxide in the range of its pressures from 0.3 to 0.6 MPa at a temperature 20 0 C not less than 0.5 ml of carbon dioxide per I g of absorbent carbon at the pressure increase on 0.1 MPa. It is necessary to emphasize that the outlet valve should safely prevent the liquid 3 coming inside the capsule 5. It is explained by the fact that at the spray container maintenance or keeping CO 2 gas pressure inside the body 2 can quickly exceed CO 2 pressure in the capsule 5 and in such a way there exists danger of the components receipt of the dispensing liquid 3 in the capsule 5. If the dispensing liquid 3 doesn't contain substances, possessing greater that CO 2 gas sorption warmth in the sorbent material, in this case a part of the dispensing liquid 3, arrived in the capsule 5, will not be dispensed, that will worsen the pressurized dispensing container consumer qualities, and if in the composition of the dispensing liquid 3 there are components, possessing greater that CO 2 gas sorption warmth in sorbent - absorbent carbon, then this can also lead to the unplanned pressure boost of gas in the spray container body 2 and to the changing of the components concentration of the dispensing liquid 3, that can also have an effect on the pressurized dispensing container consumer quality.

c Id: 3779060 12 As in the offered engineering decision the capsule 5 is made in the gas proof cover, and the outlet valve 7 has an ability by its function fulfillment to let through gas blisters 6 only from the capsule 5, then the receipt of undesired substances inside the capsule 5 is excluded. As the dispensing liquid 3 one can use water, different perfume, medical etc., liquid compositions, emulsions, suspensions and finely dispersed powders (pseudo-liquid). In case of the finely dispersed powders dispersing gas from the capsule 5 comes into the bottom of the spray container body 2, creating thus a pseudo-liquid layer. The invention can be used in spray containers from the application in medicine, household chemistry, perfumery etc.
