FIELD OF THE INVENTION
The present invention relates to the field of medical treatment systems, more particularly, to a system and method for treating an infestation of head lice.
BACKGROUND OF THE INVENTION
Infestation of the human body by lice is an increasingly prevalent social and health problem in many countries in the world. Lice infest hundreds of millions of people each year. Lice are very small insects, about 2-3 mm in length. They deposit eggs either on a hair or fabric fiber and attach them firmly with a cement-like excretion.
The life cycle of lice comprises an egg stage, three nymphal stages, and an adult stage, and takes about one month. A female louse lays approximately 100 eggs, which are glued to hairs of the host. The eggs generally hatch in about six to ten days, depending on temperature. The nymphs, (the larval stage in insect development), and adults suck blood, causing disturbance (itching, also known as pruritus) and secondary infection. The empty shells remaining after the nymphs emerge from the eggs look like white grains of sand.
Lice, being insects, use tracheae for respiration. Tracheae are a system of internal tubes (invaginations of the cuticle) penetrating the insect's body, through which air diffuses or is being pumped directly to the body tissues. Within body cells, chemical respiration takes place in the mitochondria, where ATP is produced under oxygen consumption.
The common treatment methods against lice involve liquids or lotions.
An apparatus and process for killing human and animal vermin, which discloses treatment of lice within a gas-tight garment by using a volatile liquid, specifically methyl-formate, that is spread on a pad inside the garment and evaporates inside the garment, is described in U.S. Pat. No. 2,033,357 of Riker et al. patented 1936.
A method and device for eradicating lice and nits form an infested area, particularly the scalp of a human being, comprises a plastic or rubber cap for covering the head of a human being, and means for filling the cap with an inner gas, such as carbon dioxide from a pressurized-gas cartridge, in order to suffocate the lice and the nits enclosed by the cap, is described in European Patent Application No. 86630160.9, publication No. EP0221004, of Scolnik et al. filed Oct. 30, 1986.
A formulation for controlling human lice, which discloses pediculicidal formulations comprising a spinosyn, or a physiologically acceptable derivative or salt thereof, and a physiologically acceptable carrier, and methods of controlling lice infestations in a human with these formulations are provided in International Patent Application No. PCT/US1999/013925, publication No. WO/2000/001347, of Snyder, filed Jun. 21, 1999.
A pediculicide composition, in particular, a composition comprising a sesquiterpene alcohol and a suitable carrier, is described in International Patent Application No. PCT/AU2006/001720, publication No. WO/2007/056813, of Found, filed Nov. 17, 2006.
A method and composition for controlling lice on an organism is described in International Patent Application No. PCT/NL2000/000196, publication No. WO/2000/057704, of Kussendrager et al. filed Mar. 23, 2000.
All of these applications are incorporated by reference for all purposes as if fully set forth herein.
Although the various breeds of human lice are related, each of them has specific characteristics with regard to habitat and feeding. For example, head lice are small hard-shelled ectoparasites which cling to hair shafts while feeding, mating and laying eggs. The louse must remain on the head or it will die within a short period of time. Head lice proliferate at an incredible rate. A louse is ready to mate and reproduce within 10 hours after hatching. Under ideal conditions, a female louse may produce up to 300 eggs in its lifetime. Ideal conditions include an adequate food supply, environmental temperatures from about 28° C. to about 32° C., and relative humidity of about 70% to about 90%.
The louse's hard chitinous exoskeleton serves as protection from external elements. Lice eggs (or ova) are similarly protected by a chitinous sheath surrounding the eggs and attached to the hair shaft. Although lice may be affected by the use of an insecticide, the eggs often remain resistant to attack. Thus, present art optimum treatment of a lice infestation includes both a pediculicide, which kills the adult lice, and an ovicide, which interrupts the development of the eggs.
Treatment for eliminating head lice traditionally included home remedies such as smearing mayonnaise, olive oil, hair pomade, or some other heavily viscous material about an infested scalp coupled with rigorous combing of the hair and meticulous removal of adult lice, nymphs, and nits. Though these home remedies do not kill head lice, the prevailing thought is that the viscosity of the material makes it hard for head lice to roam about the scalp, making for easy removal. Such home remedies are usually ineffective at controlling head lice due to the ability of the lice to revive rapidly once these materials are removed.
More effective treatments for eliminating head lice involve massaging the infested scalp with over-the-counter (OTC) topical creams containing active insecticides. Because of their potential toxicity to the human host, the use of these topical formulas is regulated by the FDA. Over-the-counter insecticides typically have pyrethrins or permethrin as active ingredients
Biologically active agents have been used for some time in attempts to control lice. For example, lindane (gammabenzene hexachloride), organophosphates (malathion), natural pyrethrins, and synthetic compounds known as pyrethroids (such as permethrin) have been used as pediculicides in lice treatment formulations. These agents however, have drawbacks. Lindane has a poor safety profile, and lice have developed resistance to it. Natural pyrethrin requires frequent follow-up treatments because it provides only short term residual action. Synthetic pyrethroids, although more effective against lice than natural pediculicides, are often more toxic to the subject being treated.
Strains of head lice have been identified worldwide which are resistant to all currently available topical treatments. Possible neural damage to the human host prevents raising the insecticide levels above the current threshold in an attempt to combat these newer treatment resistant head lice.
A system for treating lice with gaseous compounds in an airtight space is described in European Patent Application No. 09163262.0 publication No. EP2255778, of Ritterband, Menachem and Shlomi, Yinon, which is incorporated by reference for all purposes as if fully set forth herein.
FIG. 1a of the prior art illustrates a system for treating lice and nits 1, on a head 10 of a patient, according to European Patent Application No. 09163262.0.
A container 14 is connected on both ends to connecting tubes 13. In this configuration, the container 14 contains active agent 15 in a gas state. The flow of the active agent 15 is achieved by releasing vaporizing and circulating gas 12 from within a vaporizing and circulating gas source 11. The releasing is enabled by opening a valve, for example by a gas source handle 11a. 
FIG. 1b of the prior art shows a container 14, according to the European Patent Application No. 09163262.0.
The container 14 contains an immersed material 16, which is a sponge, immersed with active agent 15. In this configuration, an active agent 15, of acetic acid type is inserted into the container 14 and then evaporates.
This method of storage of the active agent 15 is insufficiently effective.
FIG. 2 of the prior art is a schematic block diagram of a system for treating lice and nits 1, according to the European Patent Application No. 09163262.0.
A vaporizing and circulating gas source 11 contains a vaporizing and circulating gas 12, which during activation flows through a connecting tube 13 to a container 14. Container 14 contains active agent 15 and immersed material 16, such as a sponge.
The vaporizing and circulating gas 12 vaporizes the active agent 15 and causes it to flow through a connecting tube 13 to a cap 17 for the purpose of performing the treatment of lice and nits.
None of the prior art provides a sufficiently effective solution, and there is therefore a need for a system and a method for treating an infestation of head lice.
SUMMARY OF THE INVENTION

Note: when the association of a reference number to a specific one of the two embodiments of the present invention needs to be distinguished, the reference number associated to the first embodiment will be marked with a single apostrophe, and the reference number associated to the second embodiment will be marked with a double apostrophe, for example: system for treating lice and nits 1′, (in accordance with the first embodiment of the present invention), and system for treating lice and nits 1′′, (in accordance with the second embodiment of the present invention).
The disclosed invention describes a system and method for treating lice on a patient's head. The invention utilizes a cap for defining the space around the treated hair, and an airtight sealing of the space around the treated hair, to apply an active agent for treating lice. Reducing the volume that is treated allows using a small amount of active agent, such that in case of releasing the active agent outside the cap, the patient faces no danger due to the strong dilution of the active agent. Keeping the active agent compressed in a container enables a rapid delivery of the active agent into the airtight space.
This specification is not intended in any way to limit the present invention to any specific method of applying pressure to the material in order to deliver it in gas form.
The subject matter regarded as the invention is particularly pointed out and distinctly claimed in the concluding portion of the specification. The invention, however, both as to organization and method of operation, together with objects, features, and advantages thereof, may best be understood by reference to the following detailed description when read with the accompanying drawings in which:
FIG. 3a illustrates a cap 17 of a first embodiment of a system for treating lice and nits 1′, (not fully shown in the present drawing), according to the present invention, upon which a section plane a-a is marked.
Cap 17 is shown in the present illustration from its inside, with its central part pulled and diverted toward the left side of the illustration, and being equipped with a distributor 17a. During treatment, the distributor 17a receives a supply of active agent 15 at a higher pressure than that of the environment.
The active agent 15 comes through the connecting tube 13 and the distributor 17a disperses its circulation to several injection tubes 17b. The injection tubes 17b are attached to the interior side of the cap 17c. An injection tube 17b includes openings through which the active agent 15 flows.
FIG. 3b is a cross sectional view a-a illustration of an injection tube 17b, of the cap 17 of the first embodiment of the system for treating lice and nits 1′, according to the present invention.
The injection tube 17b can be composed of a thin material, relative to its lateral section, for example fabric, folded double lengthwise. Along the injection tube edges 17e are injection tube stitches 17d, which connect these edges however do not seal them, and comprise a flow opening 17f. 
FIG. 4a is a side view schematic illustrations of a container 14′ of the first embodiment of the system for treating lice and nits 1′, according to the present invention.
FIG. 4b is an isometric view schematic illustration of an active agent container 14′ of the first embodiment of the system for treating lice and nits 1′, according to the present invention.
FIG. 4c is a top view schematic illustration of an active agent container 14′ of the first embodiment of the system for treating lice and nits 1′, according to the present invention, upon which a section plane b-b is marked.
FIG. 4d is a cross sectional view b-b illustration of an active agent container 14′ of the first embodiment of the system for treating lice and nits 1′, according to the present invention.
The present illustration shows the container 14′, in storage state, when it is inactive, and contains immersed material 16 and active agent 15 in a liquid state, absorbed within the immersed material 16. The immersed material 16 can be a sponge in a single lump, several smaller lumps, or a large number of unbound small crumb-size pieces, spherical or of another shape, including amorphous pieces, or porous particles. The pieces of the immersed material 16 improve the evaporation.
The container 14′ can be designated for single-time use.
A particularly effective form of the active agent 15 for this specific purpose is acetic acid (CH3COOH).
A sufficient quantity of acetic acid for one treatment, stored in container 14′, can be in the range of 1 to 5 cubic milliliters.
During circulation of the vaporizing and circulating gas source 11, (not shown in the present illustration), the liquid part of the active agent 15, if there is part of it in a liquid state, evaporates, and only its vapors emerge and flow from the container 14′.
The container 14′ includes a container main wall 14a′, whose shape can be as of a cylindrical tube wall, with a circular section, having at each of its ends, the container main wall end 14aa, a container end wall 14b, the shape of each can include a conical segment, which tapers and becomes narrower in the outward direction, having a circular section, which extends into a segment resembling a cylindrical tube wall, with a circular section, creating at it center a fluid passage 14c. 
One fluid passage 14c serves as an inlet, while the other serves as an outlet.
In storage state, the container 14′ is closed on both ends by lids 14d which are removed from their places prior to use. Near the end of each fluid passage 14c, a sealing disc 14e′ can be placed to prevent any leakage of active agent 15 during storage.
The sealing discs 14e′ are broken during preparation for use, for example during assembly of a connector 13a, (not shown in the present illustration, shown in FIG. 5).
Furthermore, the container 14′ can include two o-ring seals 14g and two filters 14l′.

FIG. 9 is an isometric view schematic illustration of a connecting tube 13, according to the embodiments of the present invention.
Connecting tube 13 serves as a tube enabling flow of active agent 15 and of vaporizing and circulating gas 12 from the container 14′′ to the cap 17.
The connecting tube 13 can also serve as a tube enabling flow of vaporizing and circulating gas 12 from the vaporizing and circulating gas source 11 to container 14′′.
The option of using connecting tube 13 or connecting tubes 13 is in no way limiting the present invention, and connections can be made of the container 14′′ to the cap 17, and of the vaporizing and circulating gas source 11 to container 14′′, without mediation of connecting tubes 13.
(The vaporizing and circulating gas source 11, vaporizing and circulating gas 12, container 14′′, active agent 15, and cap 17, are not shown in the present illustration).
Its dimensions, such as internal and external diameter, and the material composing connecting tube 13 and its features such as rigidity, flexibility, plasticity, and impenetrability, resistibility to environmental conditions in storage and during suitable use are adapted for practical purposes.
FIG. 10 is an isometric view schematic illustration of an adapter 18 and an adapter seal 18a, according to the second embodiment of the present invention.
Adapter 18 enables connecting capsule 20, (not shown in the present drawing), to the vaporizing and circulating gas source 11, (not shown in the present drawing), directly, or by mediation of connecting tube 13, (not shown in the present drawing).
In addition, adapter 18 also assists in breaking seals of capsule 20, (not shown in the present drawing), in order to enable flow through it and from it, as will be further described.
Adapter seal 18a is designated to prevent leakage after the connection of capsule 20 to the adapter 18, in the area of the connection, however without disrupting flow between the parts.
Its external shape, from a top view of the adapter seal 18a, as well as its dimensions, conform to its designated location within adapter 18.
FIG. 11a is a cross sectional isometric view c-c illustration of an external cylinder 20a of the second embodiment of the system for treating lice and nits 1′′, according to the present invention.
The cross section plane c-c can be found in FIG. 14a. 
The external cylinder 20a also serves for holding by hand and transmitting forces during connection of capsule 20 to an adapter 18, (both not fully shown in the present drawing), and for the purpose of breaking both sealing discs 14e′′, (not shown in the present drawing).
The external cylinder 20a has an external cylinder wall 20aa, having two external cylinder windows 20ab designated to receive the internal cylinder hook heads 20bba, (not shown in the present drawings), during assembly of capsule 20, and to enable them a limited range of movement.
The external side of the external cylinder 20a has a gripping means 20ac, such as rigs or roughness, and an arrow mark 20ad indicating the direction of activating force when performing the connection to the adapter 18, (not shown in the present drawing).
The gripping means 20ac enables firm grip and marks the desired location for holding.
In the external cylinder first end 20ae there is an external cylinder end wall 20af, through which an external cylinder tube 20ag passes, and its end contained within the external cylinder 20a is an external cylinder piercer 20ah. The external cylinder tube 20ag has an external cylinder tube internal length 20ai. 
The external cylinder tube 20ag enables connection of capsule 20 to a connecting tube 13, (both not fully shown in the present drawing).
In the external cylinder second end 20aj there are two external cylinder outer clips 20ak, (only one of which is shown in the present illustration), and which when connected in rotational movement of the capsule 20, (not shown in the present drawing), to the adapter 18, (not shown in the present drawing), is subject to force applied by adapter track 18f, (not shown in the present drawing), causing movement and perforation, as will be further described.
The external cylinder outer clips 20ak, and the adapter tracks 18f have a shape in a range of segments of spiral coils of identical pitch.
In other configurations according to the present invention, there can be a different number of external cylinder outer clips 20ak. 
The external cylinder 20a has an external cylinder wall internal diameter 20al. 
FIG. 11b is a cross sectional isometric view c-c illustration of a container cylinder 14m of the second embodiment of the system for treating lice and nits 1′′, according to the present invention.
The cross section plan c-c can be found in FIG. 14a. 
The container cylinder 14m has a container main wall 14a′′ with a container first end 14sa and a container second end 14sb. The container main wall 14a′′ can have several wall thicknesses, such as a container main wall first thickness 14na, in a segment starting with container first end 14sa and continuing to a depth of a container first stair depth 14pa, a container main wall second thickness 14nb, in a segment starting with container second end 14sb and continuing to a depth of a container second stair depth 14pb, a location in which a container interior ring 14od is disposed, and a container main wall third thickness 14nc, which is thicker than both of the aforementioned thicknesses, and is along the remainder of the container main wall.
The container interior ring 14od serves as a stair that provides a rest for the first carrier 14j (not shown in the present drawing) and enables convenient sealing with the sealing ring 20c (not shown in the present drawing) and adhesion of the sealing disc 14e′′ (not shown in the present drawing).
The container first internal stair 14ra serves as a support for one filter 14l′′, and the container second internal stair 14rb serves as a support for another filter 14l′′, (both filters 14l′′ not shown in the present drawing).
As a result, the container cylinder 14m, in the configuration shown in the present illustration, includes three internal stairs, a container first internal stair 14ra, a container second internal stair 14rb, and a container third internal stair 14rc. 
Likewise, the container main wall 14a′′ bears outer rings, three in the configuration shown in the present illustration, a container first outer ring 14oa at the container first end 14sa, a container second outer ring 14ob at the container second end 14sb, and a container third outer ring 14oc in between.
Each one of the container outer rings 14oa, 14ob, and 14oc has a container outer ring diameter marked in FIG. 14b, conforming to the dimensions of other elements composing capsule 20.
In the segment between the container first end 14sa and the container first internal stair 14ra, the length of which is the container first stair depth 14pa, container main wall 14a′′ has a container first internal diameter 14qa. 
In the segment between the containers second end 14sb and the container second internal stair 14rb, the length of which is the container second stair depth 14pb, container main wall 14a′′ has a container second internal diameter 14qb. 
The container first outer ring 14oa serves as a support for first carrier 14j and for good grip of one filter 14l′′ between them, (both not shown in the present drawing).
Similarly, the container second outer ring 14ob serves as a support for the second carrier 14k and the filter 14l′′ between them, (both not shown in the present drawing).
The container third outer ring 14oc helps to fix the container cylinder 14m inside the external cylinder 20a, (not shown in the present drawing), and furthermore enables the internal cylinder 20b, (not shown in the present drawing), to push the container cylinder 14m in order to cause the puncturing of a seal, as will be further detailed.
FIG. 11c is a cross sectional isometric view c-c illustration of an internal cylinder 20b, of the second embodiment of the system for treating lice and nits 1′′, according to the present invention.
The cross section plane c-c can be found in FIG. 14a. 
The internal cylinder 20b, has an internal cylinder wall 20ba having two ends, an internal cylinder first end 20bk and an internal cylinder second end 20bl. 
From the internal cylinder first end 20bk exits along the internal cylinder wall 20ba four internal cylinder slots 20bc, two of which are shown in the present illustration, emerge from the internal cylinder first end 20bk along the internal cylinder wall 20ba. 
In other configurations, there can be more or less internal cylinder slots 20bc. 
Between two adjacent internal cylinder slots 20bc, there is an elastic internal cylinder hook 20bb. This elasticity enables, during the assembly of capsule 20, (not shown in the present drawing), to dispose each internal cylinder hook head 20bba within an external cylinder window 20ab, (not shown in the present drawing), thus limiting the range of movement between the internal cylinder 20b and the external cylinder 20a, (not shown in the present drawing).
On the internal cylinder wall 20ba, at its more distant end from the internal cylinder first end 20bk, there is an internal cylinder outer ring 20bd, which is attached to an internal cylinder base 20be, which is attached to an internal cylinder base ring 20bf. 
The internal cylinder base 20be presses on the adapter seal 18a, (not shown in the present drawing), after the connection of capsule 20 to the adapter 18, (both not shown in the present drawing), thus achieving a good seal between them.
Near the closer end of the internal cylinder 20b to the internal cylinder base 20be there is an internal cylinder outer stair 20bm, which prevents movement of container 14′′ into the external cylinder 20a, when a safety-catch 21, (both not shown in the present drawing) is assembled to the container cylinder 14m, thus preventing the puncturing of seals.
Note: use of terms such as: located, attached, disposed, etc., are not in any way limiting to a specific combination of components, and according to the present invention there can be a system including various elements made of a single continuous material, which can be manufactured in a process suitable for designing its shape and attaining additional features, such as casting or machining.
For the dimensions of internal cylinder 20b to conform to other elements composing capsule 20, the following specific dimensions are particularly significant, and are indicated in the present illustration: the internal cylinder wall internal diameter 20bg, the internal cylinder wall exterior diameter 20bh, the internal cylinder base ring exterior diameter 20bi, and the internal cylinder outer ring outer diameter 20bj. 
When in the description and in the claims sections of the present patent application reference is made to the diameters of two components mounted one within the other, using the term substantially, or the like, such as in the following phrasing: “a first element having a diameter substantially equal to the diameter of a second element”, the reference is to dimensions which are very close in size, however maintain a small gap between both diameters, several orders of magnitude smaller than the dimensions of the diameters. The dimensions of the diameters and the possible tolerance are in these cases as is acceptable in engineering design to ensure that there will be longitudinal movement between both of the components in question, without excessive friction, however at the same time without excessive lateral freedom of movement.
This reference also applies to length dimensions and angular dimensions of segments of components.

The safety-catch 21 is shown mounted on the internal cylinder wall 20ba. 
The adapter 18 has adapter base 18e, this base can be a wall of the vaporizing and circulating gas source 11, (not shown in the present drawing), or a separate wall, with the adapter 18 and the vaporizing and circulating gas source 11 being connected to each other by means of a connecting tube 13, in this case the shape from a top view of the adapter base 18e can be circular.
The adapter base 18e is connected to an adapter outer cylinder 18d and an adapter inner cylinder segment 18h, and between them, on part of the adapter base 18e, there are adapter base opening segments 18i. 
The adapter base opening segments 18i are designated to facilitate the manufacturing of the adapter tracks 18f with the adapter track stoppers 18g. This applies to various methods of manufacturing, including casting and machining.
An adapter tube 18c passes through adapter base 18e and its end which is internal relative to adapter 18 is pointed and serves as an adapter piercer 18b. 
When the adapter 18 and the vaporizing and circulating gas source 11 are connected to each other directly and without mediation of a connecting tube 13, there is no need for the part of the adapter tube 18c, which protrudes beneath the adapter base 18e in the orientation shown in the present illustration.
The adapter outer cylinder inner face 18da is connected to two adapter tracks 18f, at the end of each of which is an adapter track stopper 18g.

Its Z axis serves as the adapter's symmetry axis, and plane X-Y is placed on the bottom side of the adapter base 18e. 
The external cylinder 20a is shown in the present illustration rotated at 90 degrees around axis Z relative to the original section plane.
Prior to the engagement of the external cylinder 20a with the adapter 18, the external cylinder 20a is above the adapter 18, according to the defined axis system, in such an orientation that external cylinder outer clip 20ak is not above an adapter track 18f. The engagement process starts with moving the capsule 20, which for the purpose of simplicity is presented here by only the external cylinder 20a, in movement shown here as external cylinder linear movement 20l in a direction along axis Z, and in a direction opposite to its direction.
FIG. 17c is an isometric view schematic illustration of an external cylinder 20a and of an adapter 18 of the second embodiment of the system for treating lice and nits 1′′, according to the present invention, upon which a section plane i-i is marked.
The external cylinder 20a and the adapter 18 are engaged with each other and shown here as smaller than they are shown in the majority of illustrations of the present illustration, for purposes of convenience.
FIG. 17d is a cross sectional view i-i illustration of the external cylinder 20a and of the adapter 18 of the second embodiment of the system for treating lice and nits 1′′, according to the present invention.
After the external cylinder 20a has been inserted sufficiently deep into the adapter 18 it is manually rotated in the direction marked by the external cylinder rotational direction 20r. In this state, the adapter tracks 18f force the external cylinder outer clip 20ak to maintain the linear movement of the external cylinder 20a until it is locked.
FIG. 18a is an isometric view schematic illustration of a capsule 20, onto which is mounted a safety-catch 21, of the second embodiment of the system for treating lice and nits 1′′, according to the present invention.
The safety-catch 21 is shown in the present illustration as engaged with capsule 20. The two safety-catch stopper arms 21b are in the gap between the internal cylinder outer stair 20bm and the external cylinder second end 20aj whose size substantially equals the safety-catch stopper arm width 21c, thus preventing relative closing movement along axis Z between the external cylinder 20a and the internal cylinder 20b. 
FIG. 18b is a cross sectional view c-c illustration of a capsule 20, and a safety-catch 21, of the second embodiment of the system for treating lice and nits 1′′, according to the present invention.
The safety-catch 21 prevents relative closing movement along axis Z between the external cylinder 20a and the internal cylinder 20b. 
FIG. 18c is a cross sectional view d-d illustration of a capsule 20 and an adapter 18, of the second embodiment of the system for treating lice and nits 1′′, engaged with each other, according to the present invention.
After withdrawal of the safety-catch 21, (not shown in the present drawing), from capsule 20 and pressing capsule 20 toward the adapter 18 in the direction −Z, closing movement is achieved in this direction of the external cylinder 20a relative to the internal cylinder 20b. This movement cannot be larger than the value of an external cylinder movement range 21d. 
FIG. 19 is an isometric view schematic illustration of a container 14′′, of the second embodiment of the system for treating lice and nits 1′′, according to the present invention.
The container 14′′ includes container cylinder 14m, a first carrier 14j, a second carrier 14k, and two sealing discs 14e′′, and for as long as a sealing disc 14e′′ has not been punctured, the container 14′′ contains active agent 15.
Furthermore, according to an embodiment of the present invention, it contains immersed material 16, which in the present illustration includes a plurality of porous particles 16a. Strictly for the purpose of showing the active agent 15 and the porous particles 16a in the present illustration, part of the container main wall 14a′′ has been removed.
The plurality of porous particles 16a enables preserving the active agent 15 in liquid state during storage, and enables fast vaporization of the active agent 15 when vaporizing and circulating gas 12, (not shown in the present illustration), flows through the container 14′′.
The vaporization rate is dependent on several parameters also including: surface areas, the type of liquid, (the active agent 15), the flow speed of the vaporizing and circulating gas 12 and the temperature of the active agent 15.
According to the present invention, different kinds of vaporizing and circulating gas 12 can be used, also including Butane, Freon, and Nitrous Oxide.
Adding organic and non-organic solvents materials, such as acetone or ethanol, to vaporizing and circulating gas 12 has been found to expedite the vaporizing rate of the active agent 15.
FIG. 20 is an isometric view schematic illustration of a porous particle 16a. 
The porous particle 16ais an inert component, miniscule relative to the dimensions of the container 14, having pores 16aa. Each pore 16aa has at least one pore opening 16ab, having an opening diameter 16ac in the order of magnitude of single to several tens of microns. The porous particle 16a has a porous particle size 16ad in the order of magnitude of several tens to several hundreds of microns. The porous particle size 16ad is the largest distance between two surface points 16p upon porous particle surface 16ae. The porous particle 16a can be amorphous or of a defined spatial shape, such as a cylinder, a sphere, etc., and it can be composed of materials such as thermoplastic polymers, glass, etc.
