Definitions

  • the invention relates to packaging technology and can be used, for example, in aerosol dispensers which serve for stretching paint and varnish casings, in the perfume industry, in fire fighting technology and also for atomising household chemicals and carbonating beverages, and the like.
  • a spray container with a disposed in an opening of a housing wall distribution valve, a spray liquid, a propellant, one with the spray liquid saturated and contained in the housing sorbent is known (International application PCT / RU92 / 00129, with the international filing date of 26.06.92, the priority date of 29.06.91, the international publication number WO 93/00277 of 07.01.93 and the international class B65D 83 / 14).
  • the refilling of this spray container is carried out by means of a sorption agent and release agent filling valve and by means of the valve which distributes the spray liquid, so that a high degree of filling of the package with a spray liquid and a high refilling capacity can be achieved.
  • the known spray container requires the provision of a special device for refilling the spray container, namely the provision of automated lines for refilling these spray containers, because the existing filling lines are unable to refill these spray containers, and these spray containers can be used for different spraying substances and gases are not reused, because the cleaning of the housing of the spray container and the preparation of a sorbent are too complicated.
  • a spray container with a housing, disposed in an opening of a housing wall distribution valve, a spray liquid, a propellant, a housing disposed in the capsule, particles of saturated with the gas propellant and disposed in the capsule sorbent and a filter element is known, which for the Gas propellant is not dense and due to openings in a gas-tight material plays the role of a housing environment of the capsule and can cause a delay of the particles of the propellant (US Patent N 3964649 with a release date of 22.06.76, USCl 222/399).
  • the quality of sorbent saturation may be degraded by the gas propellant because substances having a greater heat absorption than the propellant may penetrate into the sorbent.
  • a gas storage canister with a gas tight housing containing particles of a gas saturated sorbent, which gas is delivered via a sealed discharge channel is also known (RU patent 2086489, international class B65D83 / 14, dated 10.08.1997).
  • This known capsule is characterized in that a gas outlet is blocked by means which reduce the degree of saturation of the sorbent by gas and is directed to a given technical opportunity for its opening, thereby narrowing potential uses of the capsule.
  • US Pat. No. 3,813,041 discloses a capsule for storing liquefied gas under pressure in a container from which the liquid as gas can escape into an atmosphere or a region of lower pressure than the storage pressure.
  • the container further comprises a solid polymer on which the liquid acts as a swelling agent, so that the polymer becomes a gel which releases the stored liquid as a gas.
  • the cavity of the capsule is filled with solid pieces of polymer, and the capsule is not sealed, but provided with a gas discharge opening.
  • a gas storage capsule is also known from FR 2 690 142 A1, in which the housing consisting of two housing parts in the upper housing part has a complicated membrane part, which releases an opening of the valve under pressure, so that propellant gas from the lower housing part through this opening and a further, arranged in the upper housing part opening can escape.
  • WO 9 517 340 A discloses a gas storage capsule which is filled with a propellant gas absorbing matrix and provided with a gas discharge opening. This opening is closed with a closure which dissolves in the operating state of the gas storage capsule when immersed in an aerosol liquid of a spray container or otherwise opened when the capsule is put into operation.
  • the result achievable with the realization of the invention is to maintain a high degree of saturation of a sorbent with gas and to extend the capabilities of the capsule.
  • the housing according to the invention contains a sorbent-free cavity whose volume for receiving a predetermined Amount of gas to be sorbed in the solid state sufficient and which is provided with a means for introducing the gas in a solid state in the housing.
  • the sealing of the discharge channel can be effected in that the valve is provided with an elastic element which allows the gas discharge from the capsule only at an overpressure of a predetermined value in the capsule against the external pressure of the capsule.
  • the housing may be formed as a cylinder, which is composed of two or more parts.
  • the valve can be arranged at a connection point of the housing parts.
  • an elastic element of the valve can serve a housing part, which is designed as a ring lip.
  • the sealed discharge channel may be provided with a molecular sieve that allows only molecules of the sorbing gas to pass through.
  • a free cavity is formed according to the invention in the capsule, in which a predetermined amount of the gas to be sorbed is taken up in the solid state.
  • a capsule (Fig. 1) comprises a housing 1, particles of a sorbent 2 for sorption of gas (the gas is not shown in Fig. 1), a sealed discharge channel 3 and a sorbent-free cavity in which a predetermined amount of gas to be sorbed is present in solid form.
  • the sealing of the discharge channel 3 may be formed as a valve, which is provided with an elastic element which allows the release of gas from the capsule 1 only under an overpressure of a predetermined value relative to the external pressure of the capsule.
  • the elastic element 5 may be formed as an elastic ring, as shown in Fig. 2.
  • This ring is arranged in an exhaust outlet of the sealed discharge channel, which is formed in the given training variant by a connection between parts 6 and 7 of the housing.
  • the ring opens the exhaust outlet of the capsule only when the pressure difference between the inner surface and the outer surface of this ring exceeds the working pressure difference. When the gas is exceeded, gas is emitted via the exhaust outlet of the duct 3 expelled.
  • the elasticity of the elastic ring 5 which is made for example of rubber, determined by the necessary, a pressure compaction-generating Einsinkverformung, the overpressure on the working pressure difference causes stretching of the ring.
  • the elastic member 5 may be formed as a ring lip, which is formed by a part of the housing parts, as shown in Fig. 3.
  • This annular lip is the simplest embodiment, which does not require mutual positioning of a mounting surface and which provides a tight seal of the surfaces of the housing parts 6 and 7.
  • a part 7 arranged on the inside of the sealing unit can be provided with slots 9 in the retaining strip, so that the movement of the parts during the installation of the part 6 is facilitated.
  • the element 5 As a membrane, as an elastic pressure cap, clamp, wedge and other known components having a certain pressure value of the elastic element 5 and a possibility of gas delivery.
  • the elastic element 5 can be formed as a pressure cap, which consists for example of rubber and is arranged in a window 10 of the housing 1, as shown in FIG. 4 can be seen.
  • this can serve as a valve which closes an opening of the window 10 after filling the capsule with particles of the sorbent 2 and with the gas to be sorbed in the solid state.
  • the sealing of the sealed discharge channel 3 can be carried out by means of a molecular sieve take place, as shown in Figs. 1 and 5.
  • the molecular sieve is disposed in an exhaust outlet of the sealed discharge channel 3, which is formed in the given design variant of a solid housing.
  • Such an element serves to pass only molecules of the gas to be sorbed via the discharge channel and interferes with the penetration of larger diameter molecules, such as organic chemistry, into the housing 1, these larger molecules being characteristic of structures which comprise virtually all possible applications of the invention Include capsules formed according to the invention.
  • the discharge channel may be provided with a rupture membrane 12 be.
  • the prevention of the release of gas during changes in state of the gas to be sorbed is also achieved in the presence of the seal of the discharge channel 3, which is formed for example in FIG. 2 as an elastic ring 5 or as a valve-pressure cap in the filling window 10, said sealing elements after filling of the gas and the sorbent and serve as additional means of preventing the intrusion into the housing 1 under the effect of a higher pressure than the pressure within the capsule and wherein the surrounding components cause the replacement of the gas by the sorbent or the required quality of the environment as in the case of using the capsule as the source of a gas propellant in the perfume aerosol dispensers.
  • These means may be porous elements which are formed as part of the housing and as a grid in an inlet opening of the channel 3 or as inserts in the form of a molecular sieve 11, which separates a cavity adapted to the particles of the sorbent from the mouth of the channel 3 and as special, gas-permeable filter element is formed.
  • the elastic element 5 may be formed as an elastic stocking, which covers the housing such that in the absence of the differential pressure on the inside and outside of the housing 1, the delivery of the gas is blocked from the capsule.
  • the capsule works like this:
  • the internal overpressure in the capsule does not reach a preset value until the time the solid state gas to be sorbed is submerged evaporates the action of the environment and does not saturate the sorbent to a given value; This is caused by the reduced absorption temperature that results from heat absorption during the gas transition state.
  • the gas-transfer state causes the pressure in the capsule to increase, and the elastic element 5, for example, as a resilient sealing lip 8 (Fig 3) is opened and is expressed under the action of the capsule internal pressure from a settling surface, whereby the cavity with the sorbent 2 is connected to the surrounding environment of the capsule via the discharge channel 3. Therefore, gas leaves the capsule until the external pressure of the capsule has not increased to a value different from the pressure value in the cavity of the sorbent 2 from the intended value. Due to its own elasticity, the elastic sealing element 5 (FIGS. 1, 2 and 4), 8 (FIG. 3) then returns to the initial position and blocks the passage of the gas from the cavity with the sorbent 2 through the exhaust outlet of the channel 3 ,
  • the gas is supplied to the capsule before filling the capsule with the sorbent.
  • the capsule is formed as a cylinder of two or more parts.
  • Such a refilling method is advantageous for operation in a conveyor mode which precedes immediately, provided a capsule in the device containing it, for example an aerosol dispenser, for the purpose of maximizing the use of the gas contained in the capsule.
  • the typical time of state transition of CO 2 (assuming CO 2 in a densified solid state plastic cylinder) is ten seconds, more than an order of magnitude exceeding typical operating speeds in industrial aerosol operating lines.
  • the amount of gas expelled from the capsule within the spray container should not be less than 750 ml or about 1.5 g when using CO 2 gas.
  • the spray liquid If water or water-based structures are used as the spray liquid to provide the necessary pressure within the package, it is also necessary to take into account the absorption of the gas by the water which desorbs from the capsule for an initial pressure of 0.75 MPa of 0.4g additional gas required, and to consider filling the free volume with gas requiring 0.4g more gas.
  • the total amount of the gas filled in the capsule is about 3 g at a loss amount in refilling.
  • the required amount of sorbent should be about 5g, so that a volume of not less than 12ml at a filling density by a sorbent of the capsule of 0.4 g / ml is required.
  • the volume required for the cavity which is necessary for the adaptation of CO 2 in its solid state and with its given amount of 2.5 g, is about 2.5 ml (in the case of the condensation of the solid state up to 1 g / ml).
  • the gas CO 2 , Ar, N 2 , O 2 , N 2 O and as sorbent an activated carbon, zeolite, silica gel or mixtures thereof.
  • sorbents e.g., the activated carbon + zeolite
  • the sorbent prepared for refilling in which the preparation in the degasification by, for example, a preliminary pumping out with heat supply, is supplied to the housing 1 of the capsule and then the capsule, which uses, for example, a window 10 in the housing 1, then it enters the condensed, solid state CO 2 (so-called dry ice), which has the shape of a tablet, pill or ball, and then into the window 10, which is located in the immediate vicinity of an exhaust outlet and in which the elastic element 5 in the given Variant is designed as a rubber pressure cap.
  • CO 2 condensed, solid state CO 2
  • the invention can be used in medicine, in the fire fighting industry for the formation of pressure in extinguishing equipment, in household chemistry, in the perfume industry, as a gas source for inflatable bodies and for beer kegs, etc.
