     FIELD OF THE INVENTION 
       [0002]    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 
       [0003]    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. 
         [0004]    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. 
         [0005]    Lice, being insects, use tracheae for respiration. Tracheae are a system of internal tubes (invaginations of the cuticle) penetrating the insect&#39;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. 
         [0006]    The common treatment methods against lice involve liquids or lotions. 
         [0007]    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. 
         [0008]    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. 
         [0009]    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. 
         [0010]    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. 
         [0011]    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. 
         [0012]    All of these applications are incorporated by reference for all purposes as if fully set forth herein. 
         [0013]    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%. 
         [0014]    The louse&#39;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. 
         [0015]    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. 
         [0016]    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 
         [0017]    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. 
         [0018]    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. 
         [0019]    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. 
         [0020]      FIG. 1   a  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. 
         [0021]    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  11   a.    
         [0022]      FIG. 1   b  of the prior art shows a container  14 , according to the European Patent Application No. 09163262.0. 
         [0023]    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. 
         [0024]    This method of storage of the active agent  15  is insufficiently effective. 
         [0025]      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. 
         [0026]    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. 
         [0027]    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. 
         [0028]    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.

         [0217]    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). 
         [0218]    The disclosed invention describes a system and method for treating lice on a patient&#39;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. 
         [0219]    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. 
         [0220]    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: 
         [0221]      FIG. 3   a  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. 
         [0222]    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  17   a . During treatment, the distributor  17   a  receives a supply of active agent  15  at a higher pressure than that of the environment. 
         [0223]    The active agent  15  comes through the connecting tube  13  and the distributor  17   a  disperses its circulation to several injection tubes  17   b . The injection tubes  17   b  are attached to the interior side of the cap  17   c . An injection tube  17   b  includes openings through which the active agent  15  flows. 
         [0224]      FIG. 3   b  is a cross sectional view a-a illustration of an injection tube  17   b , of the cap  17  of the first embodiment of the system for treating lice and nits  1 ′, according to the present invention. 
         [0225]    The injection tube  17   b  can be composed of a thin material, relative to its lateral section, for example fabric, folded double lengthwise. Along the injection tube edges  17   e  are injection tube stitches  17   d , which connect these edges however do not seal them, and comprise a flow opening  17   f.    
         [0226]      FIG. 4   a  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. 
         [0227]      FIG. 4   b  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. 
         [0228]      FIG. 4   c  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. 
         [0229]      FIG. 4   d  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. 
         [0230]    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 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. 
         [0231]    The container  14 ′ can be designated for single-time use. 
         [0232]    A particularly effective form of the active agent  15  for this specific purpose is acetic acid (CH 3 COOH). 
         [0233]    A sufficient quantity of acetic acid for one treatment, stored in container  14 ′, can be in the range of 1 to 5 cubic milliliters. 
         [0234]    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 ′. 
         [0235]    The container  14 ′ includes a container main wall  14   a ′, 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  14   aa , a container end wall  14   b , 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  14   c.    
         [0236]    One fluid passage  14   c  serves as an inlet, while the other serves as an outlet. 
         [0237]    In storage state, the container  14 ′ is closed on both ends by lids  14   d  which are removed from their places prior to use. Near the end of each fluid passage  14   c , a sealing disc  14   e ′ can be placed to prevent any leakage of active agent  15  during storage. 
         [0238]    The sealing discs  14   e ′ are broken during preparation for use, for example during assembly of a connector  13   a , (not shown in the present illustration, shown in  FIG. 5 ). 
         [0239]    Furthermore, the container  14 ′ can include two o-ring seals  14   g  and two filters  14   l′.    
         [0240]      FIG. 4   e  is an isometric view schematic illustration of filter compartment  14   i  and a filter  14   l ′, of the container  14 ′, (not shown in the present drawing), of the system for treating lice and nits  1 ′, according to the first embodiment of the present invention. 
         [0241]    The present illustration shows one possible configuration for installing the filter  14   l ′ in its place, including a filter compartment  14   i  composed of two parts, a filter compartment first disc  14   ia , and a filter compartment second disc  14   ib  each of which has filter compartment disc holes  14   ic , with the filter  14   l ′ disposed between them. 
         [0242]      FIG. 5  is an isometric view schematic illustration of a vaporizing and circulating gas source  11 , a container  14 ′, a connector  13   a  and a connecting tube  13 , of the first embodiment of the system for treating lice and nits  1 ′, according the present invention. 
         [0243]    The present illustration presents a vaporizing and circulating gas source  11  which is connected directly to the container  14 ′. Likewise, the connecting tube  13  is also connected to the container  14 ′, a connection made, in the case of the present illustration, by means of connector  13   a.    
         [0244]      FIG. 6   a  is a flow chart that schematically illustrating of a method of treating lice and nits on a head  10  of a patient, according to some embodiments of the present invention, the method including the stages of: 
         [0245]    (a) mounting a cap  17  over the head of the patient, the cap  17  includes an inlet tube  13 , a distributor  17   a , and injection tubes  17   b , (stage  82 ); 
         [0246]    (b) connecting a container  14 ′ to the inlet tube  13 , the container  14 ′ includes an active agent  15  in liquid state absorbed in an immersed material  16 , (stage  83   a ); 
         [0247]    (c) connecting the container  14 ′ to a vaporizing and circulating gas source  11 , (stage  83   b ); 
         [0248]    (d) delivering vaporizing and circulating gas  12  through the container  14 ′, and evaporating the active agent  15 , the vaporizing and circulating gas  12  may be air or another suitable gas, or a mixture of suitable gases, (stage  84 ); 
         [0249]    (e) waiting at least a predetermined minimal duration, (stage  85 ); and 
         [0250]    (f) removing the cap  17  from the head  10  after the predetermined minimal duration, (stage  86 ). 
         [0251]    Note: the order of performing some of the stages can differ from what is shown in the flow charts of the present illustration, particularly the order of stage  83   a  and stage  83   b.    
         [0252]      FIG. 6   b  is a flow charts that schematically illustrating a method for connecting the container  14 ′ to the vaporizing and circulating gas source  11 , which are sub-stages of stage  83   b , according to a second embodiment of the present invention, the method including the sub-stages of: 
         [0253]    (ci) holding external cylinder  20   a  of capsule  20 , with the capsule  20  containing the container  14 ″, which contains active agent  15  and porous particles  16   a , (sub-stage  92 ); 
         [0254]    (cii) removing a safety-catch  21  from the capsule  20 , (sub-stage  93 ); 
         [0255]    (ciii) partially inserting an internal cylinder  20   b , of the capsule  20  into an adapter  18 , which includes an adapter tube  18   c , (sub-stage  94 ); 
         [0256]    (civ) after a performing a linear movement of the external cylinder ( 20   a ), the external cylinder second end ( 20   aj ) is halted within the adapter  18 , and continuing pressing of external cylinder  20   a  in linear movement toward the adapter  18  and rotating it while adapter tracks  18   f  apply forces to the external cylinder outer clips  20   ak  until the linear and rotational movement between external cylinder  20   a  and adapter  18  are stopped and they are locked together by force of friction, as a result of the contact generated between external cylinder outer clip  20   ak  and adapter track stoppers  18   g , (sub-stage  95 ); and 
         [0257]    (cv) in the course of the linear movement of the external cylinder  20   a  with regard to the internal cylinder  20   b , perforating two sealing discs  14   e ″ to enable flow from and through container  14 ″ (sub-stage  96 ). 
         [0258]    It has been found that for effective treatment, active agent  15  can be used at a time range of 5 seconds to 5 minutes, with the option for recurrent treatment in intervals of two to ten days. The quantity per treatment is of active agent  15 , which in liquid state in storage takes up a volume of 0.5-5.0 cubic milliliters. 
         [0259]      FIG. 7  is a schematic block diagram of a system for treating lice and nits  1 ″, according to a second embodiment of the present invention. 
         [0260]    The container  14 ″ is within a capsule  20 . Prior to activation, for the purpose of performing treatment, capsule  20  is partially inserted into adapter  18 , thus perforating seals and enabling flow of vaporizing and circulating gas  12  from the vaporizing and circulating gas source  11  through the adapter  18  to the container  14 ″. Adapter  18  can be connected to circulating gas source  11  directly or by means of connecting tube  13 . 
         [0261]    The vaporizing and circulating gas  12  vaporizes active agent  15  and circulates it for the purpose of treating lice, through an additional connecting tube  13  to the cap  17 . 
         [0262]    Container  14 ″ can also contain an immersed material  16 , such as porous particles. 
         [0263]      FIG. 8  is an exploded isometric view schematic illustration of a capsule  20  and a safety-catch  21 , according to the second embodiment of the present invention. 
         [0264]    Capsule  20  includes the parts shown in the present illustration, the structure of each of which and its function, as well as the manner in which they compose capsule  20 , and the manner in which they move and function will be described in further figures and their accompanying description. 
         [0265]    The typical parts composing the capsule  20  are: an external cylinder  20   a , an internal cylinder  20   b , two sealing rings  20   c , and a container  14 ″. Container  14 ″ includes a first carrier  14   j , and a second carrier  14   k , two sealing discs  14   e ″, and two filters  14   l″.    
         [0266]    The safety-catch  21 , when it is engaged with capsule  20 , prevents movement between the external cylinder  20   a  and the internal cylinder  20   b  as will be further described in detail. 
         [0267]    This list of parts is in no way limiting the present invention, and a capsule  20  including additional parts, less parts, and/or different parts is possible according to the present invention. 
         [0268]      FIG. 9  is an isometric view schematic illustration of a connecting tube  13 , according to the embodiments of the present invention. 
         [0269]    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 . 
         [0270]    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 ″. 
         [0271]    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 . 
         [0272]    (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). 
         [0273]    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. 
         [0274]      FIG. 10  is an isometric view schematic illustration of an adapter  18  and an adapter seal  18   a , according to the second embodiment of the present invention. 
         [0275]    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). 
         [0276]    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. 
         [0277]    Adapter seal  18   a  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. 
         [0278]    Its external shape, from a top view of the adapter seal  18   a , as well as its dimensions, conform to its designated location within adapter  18 . 
         [0279]      FIG. 11   a  is a cross sectional isometric view c-c illustration of an external cylinder  20   a  of the second embodiment of the system for treating lice and nits  1 ″, according to the present invention. 
         [0280]    The cross section plane c-c can be found in  FIG. 14   a.    
         [0281]    The external cylinder  20   a  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  14   e ″, (not shown in the present drawing). 
         [0282]    The external cylinder  20   a  has an external cylinder wall  20   aa , having two external cylinder windows  20   ab  designated to receive the internal cylinder hook heads  20   bba , (not shown in the present drawings), during assembly of capsule  20 , and to enable them a limited range of movement. 
         [0283]    The external side of the external cylinder  20   a  has a gripping means  20   ac , such as rigs or roughness, and an arrow mark  20   ad  indicating the direction of activating force when performing the connection to the adapter  18 , (not shown in the present drawing). 
         [0284]    The gripping means  20   ac  enables firm grip and marks the desired location for holding. 
         [0285]    In the external cylinder first end  20   ae  there is an external cylinder end wall  20   af , through which an external cylinder tube  20   ag  passes, and its end contained within the external cylinder  20   a  is an external cylinder piercer  20   ah . The external cylinder tube  20   ag  has an external cylinder tube internal length  20   ai.    
         [0286]    The external cylinder tube  20   ag  enables connection of capsule  20  to a connecting tube  13 , (both not fully shown in the present drawing). 
         [0287]    In the external cylinder second end  20   aj  there are two external cylinder outer clips  20   ak , (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  18   f , (not shown in the present drawing), causing movement and perforation, as will be further described. 
         [0288]    The external cylinder outer clips  20   ak , and the adapter tracks  18   f  have a shape in a range of segments of spiral coils of identical pitch. 
         [0289]    In other configurations according to the present invention, there can be a different number of external cylinder outer clips  20   ak.    
         [0290]    The external cylinder  20   a  has an external cylinder wall internal diameter  20   al.    
         [0291]      FIG. 11   b  is a cross sectional isometric view c-c illustration of a container cylinder  14   m  of the second embodiment of the system for treating lice and nits  1 ″, according to the present invention. 
         [0292]    The cross section plan c-c can be found in  FIG. 14   a.    
         [0293]    The container cylinder  14   m  has a container main wall  14   a ″ with a container first end  14   sa  and a container second end  14   sb . The container main wall  14   a ″ can have several wall thicknesses, such as a container main wall first thickness  14   na , in a segment starting with container first end  14   sa  and continuing to a depth of a container first stair depth  14   pa , a container main wall second thickness  14   nb , in a segment starting with container second end  14   sb  and continuing to a depth of a container second stair depth  14   pb,  a location in which a container interior ring  14   od  is disposed, and a container main wall third thickness  14   nc,  which is thicker than both of the aforementioned thicknesses, and is along the remainder of the container main wall. 
         [0294]    The container interior ring  14   od  serves as a stair that provides a rest for the first carrier  14   j  (not shown in the present drawing) and enables convenient sealing with the sealing ring  20   c  (not shown in the present drawing) and adhesion of the sealing disc  14   e ″ (not shown in the present drawing). 
         [0295]    The container first internal stair  14   ra  serves as a support for one filter  14   l ″, and the container second internal stair  14   rb  serves as a support for another filter  14   l ″, (both filters  14   l ″ not shown in the present drawing). 
         [0296]    As a result, the container cylinder  14   m , in the configuration shown in the present illustration, includes three internal stairs, a container first internal stair  14   ra , a container second internal stair  14   rb , and a container third internal stair  14   rc.    
         [0297]    Likewise, the container main wall  14   a ″ bears outer rings, three in the configuration shown in the present illustration, a container first outer ring  14   oa  at the container first end  14   sa , a container second outer ring  14   ob  at the container second end  14   sb,  and a container third outer ring  14   oc  in between. 
         [0298]    Each one of the container outer rings  14   oa ,  14   ob , and  14   oc  has a container outer ring diameter marked in  FIG. 14   b , conforming to the dimensions of other elements composing capsule  20 . 
         [0299]    In the segment between the container first end  14   sa  and the container first internal stair  14   ra , the length of which is the container first stair depth  14   pa,  container main wall  14   a ″ has a container first internal diameter  14   qa.    
         [0300]    In the segment between the containers second end  14   sb  and the container second internal stair  14   rb , the length of which is the container second stair depth  14   pb , container main wall  14   a ″ has a container second internal diameter  14   qb.    
         [0301]    The container first outer ring  14   oa  serves as a support for first carrier  14   j  and for good grip of one filter  14   l ″ between them, (both not shown in the present drawing). 
         [0302]    Similarly, the container second outer ring  14   ob  serves as a support for the second carrier  14   k  and the filter  14   l ″ between them, (both not shown in the present drawing). 
         [0303]    The container third outer ring  14   oc  helps to fix the container cylinder  14   m  inside the external cylinder  20   a , (not shown in the present drawing), and furthermore enables the internal cylinder  20   b , (not shown in the present drawing), to push the container cylinder  14   m  in order to cause the puncturing of a seal, as will be further detailed. 
         [0304]      FIG. 11   c  is a cross sectional isometric view c-c illustration of an internal cylinder  20   b , of the second embodiment of the system for treating lice and nits  1 ″, according to the present invention. 
         [0305]    The cross section plane c-c can be found in  FIG. 14   a.    
         [0306]    The internal cylinder  20   b , has an internal cylinder wall  20   ba  having two ends, an internal cylinder first end  20   bk  and an internal cylinder second end  20   bl.    
         [0307]    From the internal cylinder first end  20   bk  exits along the internal cylinder wall  20   ba  four internal cylinder slots  20   bc , two of which are shown in the present illustration, emerge from the internal cylinder first end  20   bk  along the internal cylinder wall  20   ba.    
         [0308]    In other configurations, there can be more or less internal cylinder slots  20   bc.    
         [0309]    Between two adjacent internal cylinder slots  20   bc , there is an elastic internal cylinder hook  20   bb . This elasticity enables, during the assembly of capsule  20 , (not shown in the present drawing), to dispose each internal cylinder hook head  20   bba  within an external cylinder window  20   ab,  (not shown in the present drawing), thus limiting the range of movement between the internal cylinder  20   b  and the external cylinder  20   a , (not shown in the present drawing). 
         [0310]    On the internal cylinder wall  20   ba , at its more distant end from the internal cylinder first end  20   bk , there is an internal cylinder outer ring  20   bd , which is attached to an internal cylinder base  20   be , which is attached to an internal cylinder base ring  20   bf.    
         [0311]    The internal cylinder base  20   be  presses on the adapter seal  18   a , (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. 
         [0312]    Near the closer end of the internal cylinder  20   b  to the internal cylinder base  20   be  there is an internal cylinder outer stair  20   bm , which prevents movement of container  14 ″ into the external cylinder  20   a , when a safety-catch  21 , (both not shown in the present drawing) is assembled to the container cylinder  14   m , thus preventing the puncturing of seals. 
         [0313]    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. 
         [0314]    For the dimensions of internal cylinder  20   b  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  20   bg , the internal cylinder wall exterior diameter  20   bh , the internal cylinder base ring exterior diameter  20   bi , and the internal cylinder outer ring outer diameter  20   bj.    
         [0315]    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. 
         [0316]    This reference also applies to length dimensions and angular dimensions of segments of components. 
         [0317]      FIG. 11   d  is a cross sectional isometric view c-c illustration of a first carrier  14   j  of the second embodiment of the system for treating lice and nits  1 ″, according to the present invention. 
         [0318]    The cross section plane c-c can be found in  FIG. 14   a.    
         [0319]    First carrier  14   j  has a spatial form including a first carrier cylinder  14   ja , one of whose ends has a first carrier disc  14   jb . The first carrier cylinder  14   ja  and the first carrier disc  14   jb  have a first carrier interior diameter  14   je , and the first carrier cylinder  14   ja  has a first carrier cylinder exterior diameter  14   jd . The first carrier  14   j  has a first carrier length  14   jc.    
         [0320]    The first carrier  14   j  serves as a support for filter  14   l ″ and to a sealing disc  14   e ″, (both not shown in the present drawing), disposed at two opposite ends of it. 
         [0321]    The dimension of the first carrier length  14   jc  is sufficiently long in order to prevent puncturing of sealing disc  14   e ″ by the external cylinder piercer  20   ah , (not shown in the present drawing), even when there is relative movement between them. 
         [0322]    The dimensions of the first carrier cylinder exterior diameter  14   jd  and the container first internal diameter  14   qa  are substantially equal. 
         [0323]    The first carrier  14   j  has a first carrier ring disc exterior diameter  14   jh.    
         [0324]      FIG. 11   e  is a cross sectional isometric view c-c illustration of a second carrier  14   k  of the second embodiment of the system for treating lice and nits  1 ″, according to the present invention. 
         [0325]    The cross section plane c-c can be found in  FIG. 14   a.    
         [0326]    Second carrier  14   k  has a spatial form including a second carrier cylinder  14   ka  one of whose ends has a second carrier disc  14   kb,  while the opposite end has a second carrier ring  14   kg  having second carrier ring diameter  14   kf.    
         [0327]    According to another variation the second carrier  14   k  does not include a second carrier ring  14   kg  and it is identical in shape to the first carrier  14   j  (not shown in the present drawing), with the single difference being in the dimensions of the second carrier ring disc exterior diameter  14   kh , which conform to internal cylinder wall internal diameter  20   bg , and the first carrier ring disc exterior diameter  14   jh , which conforms to the external cylinder wall internal diameter  20   al.    
         [0328]    The second carrier cylinder  14   ka  and the second carrier disc  14   kb  have a second carrier interior diameter  14   ke,  and the second carrier cylinder  14   ka  has a second carrier cylinder exterior diameter  14   kd.  The second carrier  14   k  has a second carrier length  14   kc.    
         [0329]    The second carrier  14   k  serves as a support for a  14   l ″ and a sealing disc  14   e ″, (both not shown in the present drawing), both disposed at its opposite ends. 
         [0330]    The dimension of the second carrier length  14   kc  is long enough to prevent puncturing of sealing disc  14   e ″ by the adapter piercer  18   b , (both not shown in the present drawing), even when there is relative movement between them. 
         [0331]    The dimensions of the second carrier cylinder exterior diameter  14   kd  and the container second internal diameter  14   qb  are substantially equal. 
         [0332]      FIG. 12  is a cross sectional isometric view c-c illustration of a safety-catch  21  of the second embodiment of the system for treating lice and nits  1 ″, according to the present invention. 
         [0333]    The cross section plane c-c can be found in  FIG. 14   a.    
         [0334]    The safety-catch  21  includes a safety-catch handle  21   a  and two safety-catch stopper arms  21   b , one of which is shown in the present illustration. 
         [0335]    The safety-catch stopper arms  21   b  is retractable, thus enabling manual removal of the safety-catch  21  by pulling the safety-catch handle  21   a . The safety-catch stopper arms  21   b  have a safety-catch stopper arm width  21   c , which conforms to the distance of movement the safety-catch  21  covers between the external cylinder  20   a  and the internal cylinder  20   b,  (both not shown in the present drawing). 
         [0336]      FIG. 13  is a cross sectional isometric view c-c illustration of an adapter seal  18   a  of the second embodiment of the system for treating lice and nits  1 ″, according to the present invention. 
         [0337]    The cross section plane c-c can be found in  FIG. 14   a.    
         [0338]    The adapter seal  18   a  has an adapter seal body  18   aa , the perimeter of which has two adapter seal niches  18   ab,  one of which is shown in the present illustration, whose shape, from a top view, is conform with the shape of the adapter inner cylinder segment  18   h,  (not shown in the present drawing), also from a top view, and at its center, from a top view, is an adapter seal hole  18   ac.    
         [0339]      FIG. 14   a  is a side view schematic illustrations of a connecting tube  13 , a capsule  20 , and 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 c-c is marked. 
         [0340]    The connecting tube  13  shown in the present illustration is designated to connect the capsule  20  to a cap  17 , (not shown in the present drawing), and can be made of a flexible material. 
         [0341]    The state shown in the present illustration is inactive, in which the capsule  20  and the adapter  18  are separated from each other. 
         [0342]      FIG. 14   b  is a cross sectional view c-c illustration of a connecting tube  13 , a capsule  20 , a safety-catch  21  and an adapter  18 , of the second embodiment of the system for treating lice and nits  1 ″, according to the present invention. 
         [0343]    The container first outer ring  14   oa  has a container first outer ring diameter  14   oad,  the container second outer ring  14   ob  has a container second outer ring diameter  14   obd,  and the container third outer ring  14   oc  has a container third outer ring diameter  14   ocd.  The container first outer ring diameter  14   oad,  the container second outer ring diameter  14   obd  are substantially equal in size to the external cylinder wall internal diameter  20   al , (not shown in the present drawing), and the container third outer ring diameter  14   ocd  is substantially equal in size to the internal cylinder wall internal diameter  20   bg.    
         [0344]    The safety-catch  21  is shown mounted on the internal cylinder wall  20   ba.    
         [0345]    The adapter  18  has adapter base  18   e , 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  18   e  can be circular. 
         [0346]    The adapter base  18   e  is connected to an adapter outer cylinder  18   d  and an adapter inner cylinder segment  18   h , and between them, on part of the adapter base  18   e , there are adapter base opening segments  18   i.    
         [0347]    The adapter base opening segments  18   i  are designated to facilitate the manufacturing of the adapter tracks  18   f  with the adapter track stoppers  18   g . This applies to various methods of manufacturing, including casting and machining. 
         [0348]    An adapter tube  18   c  passes through adapter base  18   e  and its end which is internal relative to adapter  18  is pointed and serves as an adapter piercer  18   b.    
         [0349]    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  18   c , which protrudes beneath the adapter base  18   e  in the orientation shown in the present illustration. 
         [0350]    The adapter outer cylinder inner face  18   da  is connected to two adapter tracks  18   f , at the end of each of which is an adapter track stopper  18   g.    
         [0351]      FIG. 15   a  is a side view schematic illustrations 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, upon which a section plane d-d is marked. 
         [0352]      FIG. 15   b  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. 
         [0353]    During movement of the external cylinder  20   a  in the direction −Z relative to the adapter  18 , the external cylinder piercer  20   ah  pierces a puncture in one sealing disc  14   e ″, and the adapter piercer  18   b  pierces a puncture in the second sealing disc  14   e″.

         [0376]    For the purpose of better understanding the relative movements between the external cylinder  20   a  and the adapter  18  when they are engaged with each other, a Cartesian X, Y, and Z axis system is defined, attached to the adapter  18 . Its Z axis serves as the adapter&#39;s symmetry axis, and plane X-Y is placed on the bottom side of the adapter base  18   e.    
         [0377]    The external cylinder  20   a  is shown in the present illustration rotated at 90 degrees around axis Z relative to the original section plane. 
         [0378]    Prior to the engagement of the external cylinder  20   a  with the adapter  18 , the external cylinder  20   a  is above the adapter  18 , according to the defined axis system, in such an orientation that external cylinder outer clip  20   ak  is not above an adapter track  18   f . The engagement process starts with moving the capsule  20 , which for the purpose of simplicity is presented here by only the external cylinder  20   a , in movement shown here as external cylinder linear movement  20   l  in a direction along axis Z, and in a direction opposite to its direction.

         [0388]    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  20   a  relative to the internal cylinder  20   b.  This movement cannot be larger than the value of an external cylinder movement range  21   d.    
         [0389]      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. 
         [0390]    The container  14 ″ includes container cylinder  14   m , a first carrier  14   j , a second carrier  14   k , and two sealing discs  14   e ″, and for as long as a sealing disc  14   e ″ has not been punctured, the container  14 ″ contains active agent  15 . 
         [0391]    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  16   a . Strictly for the purpose of showing the active agent  15  and the porous particles  16   a  in the present illustration, part of the container main wall  14   a ″ has been removed. 
         [0392]    The plurality of porous particles  16   a  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 ″. 
         [0393]    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 . 
         [0394]    According to the present invention, different kinds of vaporizing and circulating gas  12  can be used, also including Butane, Freon, and Nitrous Oxide. 
         [0395]    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 . 
         [0396]      FIG. 20  is an isometric view schematic illustration of a porous particle  16   a.    
         [0397]    The porous particle  16   a  is an inert component, miniscule relative to the dimensions of the container  14 , having porous poriferous  16   aa . Porous poriferous  16   aa  has at least one poriferous opening  16   ab,  having a poriferous opening diameter  16   ac  in the order of magnitude of single to several tens of microns. The porous particle  16   a  has a porous particle size  16   ad  in the order of magnitude of several tens to several hundreds of microns. The porous particle size  16   ad  is the largest distance between two surface points  16   p  upon porous particle surface  16   ae.  The porous particle  16   a  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.
