Definitions

  • the present invention relates to the package technics and can be used, for example, in aerosol package, used varnishdye covering, in medicine mainly for prophylaxis and breast disease treatment and local anaesthesia, as well as in perfumeery industry and also in housekeeping for household chemistry substances spraying and so on.
  • the working gas is dissolved in the spraying substance that must have some sorbent characteristics in reference to the working gas, that however limits the range of substances that can be dispersed ( sprayed ) this way.
  • This task is solved in such a way that in the method of making an excess pressure of sorbent gas in the working volume of the aerosol package the essence of which ( method ) is desorption of the sorbent gas, dissolved in a sorbent, the sorbent gas is put into the working volume and it can be, for example, carbon dioxide CO2, desorpted from sorbent having larger absorbing quality in reference to sorbent gas in a package in comparison with a spraying substance and keeping its quantity invariable while being sprayed.
  • the sorbent gas can be, for example, carbon dioxide CO2, desorpted from sorbent having larger absorbing quality in reference to sorbent gas in a package in comparison with a spraying substance and keeping its quantity invariable while being sprayed.
  • the desorpted sorbent gas is transmitted to the working volume while getting necessary differential pressure between the isolated spraying subtance and the sorbent.
  • the desorption of the sorbent gas is fulfilled in a separate capacity and/or at the periphery of the working volume of the package.
  • An activated charcoal and/or zeolite is used as sorbent in a solid phase.
  • a solid or liquid phase of the sorbent gas is used as a sorbent gas while it's being dissolved in sorbent.
  • This method of creating an excess pressure in the volume of the aerosol package decreases damage influence upon the environment while using aerosol packages.
  • Package loading with sorbent gas, for example, with CO2 just in a solid phase makes package loading operation easier.
  • the given method can be realised in package for different substance dispertion ( spraying ).
  • the construction of the aerosol unit is a sealed capacity 1, made as a cylindrical case 2 ( reffering Fig. 1 and Fig. 2 ) with a bottom 3 and a cover 4, which is hermetically connected with a dispersion head 5 and a valve 6.
  • a dispersion head 5 and a valve 6 As it is shown in Figure 1 inside of the out case 2 there is an inner casing 7 with a working volume 8, filled with dispersed substance 9 ( liquid ).
  • a sorbent 11 for example, an activated charcoal ( it can be zeolite ).
  • an activated charcoal it can be zeolite
  • the working volume 8 is communicated with the cavity 10.
  • a tube 13 for delivery of the dispersed liquid 9 to the inlet of the dispersion head 5.
  • sorbent gas there can be used carbon dioxide ( CO2 ) highly used in aerosol packages that answers ecological demands, put to sorbent gases of package, as well as - hydrocarbons, ethers and etc.
  • CO2 carbon dioxide
  • FIG. 2 there shown another possible positioning of the sorbent 11 inside the inner casing 7 of the package and/or at the top part of the working volume 8 above the dispersed ( spraying ) liquid level 9. It is also possible to position the sorbent 11 out of the outer case 2 of the package, but in this case it must be put in a separate sealed cavity, communicating by means of a supply main of the desorption gas with a gas cavity of the working volume ( it is not shown in the drawing ). In the top part of the case 2 there set a charging valve 15 for a dispersed substance. Charging valves 14 and 15 can be set at any convenient place on the outer case 2. The movement schemes of the desorption gas and dispersed substance are shown by arrows in the drawing.
  • dispersed substance supply 9 is provided by means of creating a pseudo-liquated layer by bringing desorption gas, desorpted from the sorbent 11, at the moment of pressure lavering in the working volume 8 when opening the valve 6 of the dispersion head 5.
  • the desorption gas can be brought to the working volume 8 as from the communicated with the working volume cavity 10 where there is a sorbent 11, by the way, this cavity can be got by a ring space between the inner casing 7, containing the dispersed substance 9, and the outer case 2 of the package ( see Fig. 1 ), and - from the sorbent 11, situated just in the working volume 8 ( see Fig. 2 ).
  • energy supply necessary for gas desorption from the package environment it carried out is important to provide a thermal contact between the outer case 2 of the package and the substance of sorbent 11, which is enough for gas exhaust with a sufficient speed, creating dynamics of recovery of demanded pressure in the working volume 8 at the moment after the package action that is to say immediately after the termination of a regular rate of spraying.
  • Package filling is carried out by the dispersed substance 9 and sorbent 11 and then, for example, by CO2, brought inside the cavity 10 with the sorbent either as a gas state ( at a lower temperature and heat exhaust from the package ) or as liquid (also at a low temperature, for example, about-73 C), or as a solid phase - in a state of "dry ice".
  • Package filling is made taking into account, for example such quantity of CO2 supply into the sorbent cavity which is possible to be absorpted in sorbent in given loading conditions .
  • Sorbent volume in CO2 is determined in this case as by a sorbent type and by a demanded pressure ( P ) of CO2 in the working volume at a given operation temperature ( for example, 17 C ).
  • P a demanded pressure
  • the volume ( a ) of such sorbent as activated charcoal ( type A ⁇ ) is about 33 g of CO2 for 100 g of coal at a temperature ( t ) of 17 C.
  • the initial rate of sorbent filling by CO2 is larger, i.e. it consists of 50 g of CO2 for 100 g of sorbent.
  • working gas supply from the cavity 10 with the sorbent 11 to the working volume 8 is fulfilled only when some given differential pressure between these spaces is obtained, that can be fulfilled by means of the work of the spring valve ( as the work of the valve 6 of the dispersion head 5 ), which opens the inlet of the working gas from volume 8 only at a lower pressure in the working volume (for example, on the state of sraying ) and/or at an increased pressure in the cavity 10 of sorbent (for example, at temperature increasing in this cavity ).
  • activated charcoal characterised by a rather high absorption capability as for as CO2 is concerned and relatively low price, as well as zeolite, the characteristics of which can provide higher pressure P at a given working temperature.
  • liquid sorbents for convenient loading of the package there can be used liquid sorbents as well as in combination with solid ones in the state of which there can be used some organic combinations, in particular, dimethylethertetraethylenealcohol or halogenides.

Abstract

L'invention concerne des techniques de conditionnement, c'est-à-dire des procédés de création de pression positive permettant de décharger le contenu d'un conditionnement, et vise à produire un débit uniforme de la substance atomisée, augmentant l'efficacité, ainsi qu'à diminuer les effets négatifs sur l'environnement lorsque l'on utilise des conditionnements aérosols. Un conditionnement aérosol, dans la cavité de travail duquel, lorsqu'on l'utilise, est créée une pression positive d'un gaz sorbé, comprend un récipient hermétique (1) rempli d'une substance (liquide) (9) à atomiser et doté d'un coussin de gaz contenant un gaz sorbé, par exemple CO2. Le récipient est relié à l'ajutage d'atomisation (5) par un tube (13) dont l'entrée est située au-dessous du niveau de la substance (9) à atomiser. Le conditionnement comprend également un sorbent (11) contenu dans une cavité (10) isolé de l'atmosphère extérieure à l'extérieur du récipient (1) et de la substance (9) à atomiser, tandis que ladite cavité (10) est reliée hydrauliquement au coussin de gaz. On utilise, comme sorbent, une substance ayant une capacité d'absorption de gaz sorbé supérieure à celle de la substance (9) à atomiser, par exemple le carbone ou la zéolite activée. Le procédé permet de réduire les effets nocifs de l'activité humaine sur l'environnement.
