Description

This invention relates to the field of portable refillable vaporizers known as bag, pocket or travel sprays. BACKGROUND OF THE INVENTION In known manner, a portable rechargeable vaporizer comprises a cartridge having a reservoir in which is mounted a dispensing pump. The dispensing pump comprises a pump body and a push button slidably mounted in said pump body to allow dispensing of liquid from the reservoir. The vaporizer further comprises a housing, having a main body in which is housed the cartridge, and a cap, removably mounted on the main body, to protect the push button and prevent inadvertent dispensing. Such a vaporizer comprises a large number of parts, which complicates the replacement of the cartridge and has a first disadvantage. In addition, a vaporizer with a removable cap is impractical since the latter is likely to be lost, resulting in an involuntary distribution of perfume in the bag of its user. In addition, when replacing the cartridge, it is necessary to completely replace the dispensing pump, from the pump body to the push button. In order to reduce the cost of a cartridge, it is generally provided a low quality push button, which presents a disadvantage for users. On the other hand, a cartridge is likely to be accidentally emptied when stored, for example, in a handbag, any contact with the cartridge push button resulting in perfume delivery. In addition, in use, the force applied by a user to the valve of the refillable vaporizer must be calibrated to allow optimal perfume dispensing by the cartridge while avoiding inadvertent dispensing. Finally, such a vaporizer has a limited life because its outer shell is subjected to shocks that affect its aesthetics. In addition, the outer shell is likely to get dirty when perfume flows on its case, which penalizes both the aesthetics of the case and its hygiene. In order to eliminate at least some of these drawbacks, the invention relates to an alcohol product cartridge, in particular of the perfume type, intended to be mounted in a portable rechargeable vaporizer, the cartridge comprising a reservoir storage tank, the tank extending vertically and comprising an upper dispensing opening in which is mounted a dispensing pump, the dispensing pump comprising a pump body and a dispensing tube which is slidably mounted in said pump body and which comprises a dispensing orifice extending vertically, the dispensing pump further comprising a connection head, mounted on said dispensing tube, and a resilient spring mounted between said connection head and said pump body so as to allow the dispensing a volume of alcoholic product through the dispensing orifice during vertical displacement down the connection head. Since the dispensing tube comprises a dispensing orifice extending vertically, a vertical pressure on the dispensing tube closes the dispensing orifice, which also avoids any involuntary dispensing. The use of a connection head also makes it possible to define a bearing surface sufficient to move the dispensing tube. Preferably, the storage tank has a capacity of between 1 ml and 7 ml, which distinguishes it from conventional large cartridges.

Preferably, the connection head is cylindrical, which allows to introduce such a cartridge into a vaporizer regardless of its orientation. Moreover, the cartridge can advantageously be removed in translation.

More preferably, the connecting head has an annular shoulder so as to define an upper portion and a lower portion, the diameter of the lower portion greater than the diameter of the upper portion. Such a connection head allows alignment and centering of the cartridge in a vaporizer, which is advantageous.

Preferably, the diameter of the lower part is between 3 mm and 6 mm and the diameter of the upper part is between 2 mm and 4 mm in order to form a bearing zone sufficient for the displacement of the head of the connection, while maintaining a limited cost price. According to a preferred aspect, the volume of liquid dispensed for a pressure of the connection head is between 0.05 ml and 0.15 ml, more particularly equal to or close to 0.05 ml.

Preferably, the cartridge has a vertical length of between 60 mm and 80 mm, which allows the cartridge to be in abutment in the bottom of the spray box during its actuation.

According to a preferred aspect, the connection head is adapted to slide over a range of between 3 mm and 4 mm. The invention furthermore relates to an assembly of a cartridge as presented above, and to a portable rechargeable vaporizer comprising: a protective casing, in which is housed said cartridge, comprising a vaporization orifice, spraying means housed in said shielding housing, the spray means having a pusher head having an outlet port aligned with said vaporization port and an axial connection housing, into which an inlet port opens, the cartridge connection head; and the axial connection housing of the pusher head being sealingly and removably nested, and an actuating member, adapted to be pressed by a user, which is movably mounted in said protective housing and adapted to cooperate with the spray means. The vaporizer thus advantageously comprises a pusher head, the latter being no longer secured to the cartridge as in the prior art. The cost of a cartridge is thus reduced. In addition, a better and more aesthetic pusher head 3034293 4 can be installed in the vaporizer since the same pusher head can be used with several cartridges. Preferably, the spraying means also comprise a spring tube 5 defining an internal cavity for receiving said cartridge, the spring tube being configured to damp the movement of the actuating member during pressure by a user. Thus, the pressure of the user is first damped by the spring tube before soliciting the connection head of the cartridge. In addition, a spring tube distributes all the pressure forces along the length of the vaporizer, which increases its life. Preferably, the protective housing comprises a hollow body and a base removably connected to allow access to the spray means and facilitate the renewal of the cartridge.

According to a preferred aspect, the hollow body comprises an opening in which is mounted an actuating member connected to said connection head. Preferably, the actuating member is inclined with respect to the axis of the vaporizer so as to provide an optimum pressure surface to the user, ergonomically, under his index. Preferably, the actuating member extends in the continuity due to the surface of the hollow body in order to limit the actuating surface and prevent any unintentional dispensing.

Preferably, the base of the protective housing includes a housing adapted to receive a perfume cartridge to stably maintain said cartridge.

According to a preferred aspect, the axial connection housing comprising a lower part and an upper part, the diameter of the lower part is larger than the diameter of the upper part. Thus, the cartridge can easily center in said connection head. Preferably, the radial clearance is a few 5 micrometers between the connection housing and the connection head so as to offer an optimal balance between holding and sealing. The invention also relates to a method of using an assembly as presented above, comprising a step of pressing the actuating member by an operator so as to move, in a first stroke, the cartridge abutting in said protective case then to move, in a second stroke, the connection head of the cartridge to obtain a distribution of alcoholic product. Thus, the pressure of the user is damped by the spring tube before urging the connection head 10 of the cartridge. The invention also relates to a portable rechargeable vaporizer comprising a protective casing comprising a spray orifice and spray means housed in said protective casing, the spray means are adapted to be pressed by a user and comprise a pusher head having an inlet port adapted to connect to a scent cartridge housed in said shield housing, and an outlet port aligned with said spray port, the spray means also including a spring tube defining an interior cavity adapted to receiving said perfume cartridge, the spring tube being configured to damp the movement of the pusher head upon pressure by a user. The invention also relates to a removable shell for mounting in a portable rechargeable vaporizer, the shell having a one-piece body having a cylindrical, axially extending liner shape which includes an upper opening and a lower opening, the body comprising a rear vertical slot connecting the upper opening to the lower opening so as to facilitate the alignment of the shell on the main body and to allow radial expansion of said body.

Thanks to the invention, the removable shell effectively protects a vaporizer against shock and dirt. In addition, the vertical slot allows radial deformation of said shell, which facilitates its mounting if the protective housing is deformed due to shock or thermal expansion. Finally, the one-piece structure of the shell makes it possible to limit its manufacturing cost. Preferably, the lower opening extends in a plane transverse to the axis of the shell to allow its assembly by clamping the base of the evaporator housing. Preferably, the top opening extends obliquely to the plane of the bottom opening to clear space for ergonomic actuation of the vaporizer. Preferably, the plane of the upper opening and the plane of the lower opening are inclined at an angle of between 350 and 550. Preferably, the body comprises a forward vertical notch, extending downwardly from the top opening, to allow passage of a spray during vaporization. The invention further relates to an assembly of a vaporizer as presented above and a removable shell as presented previously mounted on the protective housing of said vaporizer to protect it.

Preferably, the assembly further comprises a perfume cartridge mounted in said vaporizer spring tube.

DESCRIPTION OF ONE OR MORE EMBODIMENTS AND IMPLEMENTATION With reference to FIG. 1, there is shown a portable rechargeable vaporizer 1 according to the invention. Such a vaporizer is, for example, known as a bag, pocket spray, or travel spray vaporizer. The vaporizer 1 has a substantially cylindrical shape and is adapted to extend longitudinally along an axis X1. Subsequently, the vaporizer 1 is presented in a vertical position, the axis X1 extending vertically from bottom to top, that is to say from the bottom to the top of the vaporizer 1. Still as a For example, the vaporizer 1 has a vertical length of between 65 mm and 130 mm, preferably between 80 mm and 100 mm. Similarly, the vaporizer 1 has a diameter of between 15 mm and 30 mm, preferably between 20 mm and 30 mm. Due to its small size, the vaporizer 1 is easily transportable by a user in each of his movements.

As will be presented hereinafter with reference to FIGS. 3 and 4, the vaporizer 1 comprises a protective casing 20 and spray means, mounted in the casing 20, which are able to connect to a perfume cartridge 7 housed in said protective housing 20 to allow the vaporization of a volume of liquid from said perfume cartridge 7.

In this example, with reference to FIGS. 1 and 2, the vaporizer 1 further comprises a shell 6 adapted to be removably mounted on the protective casing 20 in order to protect and improve the aesthetics of the vaporizer 1 all by allowing the identification of the owner of the vaporizer 1 or the identification of the perfume that the vaporizer 1 distributes. The removable shell 6 is a wear part protecting the protective housing 20 which can be easily changed by a user as will be presented later.

The different elements of the vaporizer 1 will now be presented. As illustrated in FIGS. 3 and 4, the protective housing 20 comprises a hollow main body 21, also called a jacket, and a base 22 which is adapted to cooperate with the hollow main body 21 in order to close the protective housing 20.

Preferably, as shown in Figures 2, 3 and 5, the base 22 has a housing 23 adapted to receive a cartridge 7 stably before introduction into the hollow main body 21 of the protective housing 20 as will be represented by the after. In this example, the housing 23 is in the form of a vertical cylinder whose underside is blind and whose upper face is open, the internal diameter of the cylinder being substantially equal to that of the cartridge 7 as illustrated in FIG. Figure 3. Preferably, the base 22 has a flat bottom face so as to maintain the vaporizer 1 in a vertical position. More preferably, the base 22 is weighted to improve the stability of the vaporizer 1 in a vertical position. According to a preferred aspect, with reference to FIG. 5, the base 22 comprises at least two parts: a decorative outer part, preferably metallic in appearance and resistant to the components of the perfume, and an inner part, preferably in plastic mounted in said decorative outer portion. Preferably, the housing 23 is made from the material of the inner part of the base 22. The hollow main body 21 of the protective housing 20, shown in particular in FIGS. 4 and 9, has a cylindrical lower portion 24 extending vertically and 3034293 9 an upper abutment 25 projecting radially from the axis of the cylindrical lower portion 24 to allow mounting of the removable shell 6. The hollow main body 21 of the protective housing 20 is in one piece.

Similarly, as illustrated in FIGS. 9 and 10, the diameter of the base 22 is greater than the diameter of the cylindrical lower part 24. Thus, the removable shell 6 is advantageously mounted on the cylindrical lower part 24 of the hollow body 21 between the upper abutment 25 and the base 22 as shown in Figures 1 and 2. Preferably, the lower edge of the upper abutment 25 of the hollow body 21 is bevelled so as to promote the guiding of the removable shell 6 while by making it possible to hide the thickness of the removable shell 6 in the mounted position. The hollow main body 21 is opened by its lower face to allow the introduction of a cartridge 7. In this example, the hollow main body 21 is also open by its upper face so as to receive an actuating member such as illustrated in Figure 7, in particular, an actuating button 26 also called "on-push"). The lower opening extends in a plane transverse to the axis X1 while the upper opening of the hollow body 21 extends substantially in a plane oblique to the axis X1, preferably at an angle of between 350 and 550 with the plane of the lower opening. Such a housing 20 promotes access to the actuating button 26, which improves the ergonomics. With reference to FIGS. 2 and 4, the hollow main body 21 further comprises a vaporization orifice 27 extending radially with respect to the axis X of the vaporizer 1.

The actuating button 26 preferably extends in continuity with the hollow main body 21, in particular its upper stop portion 25, in order to limit its actuating surface. In other words, the actuating button 26 is integrated with the hollow main body 21 and does not project from the latter in order to limit the risk of unintended distribution. Indeed, only a localized pressure makes it possible to distribute perfume. An overall pressure on the upper part of the vaporizer 1 does not allow dispensing since the upper abutment 25 of the hollow main body 21 can not be moved.

The upper opening of the hollow body 21 being inclined, the actuating button 26 is also inclined, which improves the ergonomics of the vaporizer 1. In fact, such an actuating button 26 allows easy spraying by the user simply by using his index.

More preferably, with reference to FIG. 1, the protective housing 20 has a vertical mounting tongue 28 projecting radially outwardly from the cylindrical lower portion 24 of the hollow body 2. Such a tongue 28 facilitates guiding the removable shell 6 during assembly. The tongue 28 is preferably made of material of the hollow main body 21. The spraying means, mounted in said protective housing 20, will now be presented with reference to Figures 4, 7 and 8.

As illustrated in FIG. 4, the spraying means comprise a pusher head 4 and a spring tube 5 supporting said pusher head 4. The pusher head 4 is able to exert a pressure on the cartridge 7 as will be presented by the following.

With reference to FIG. 4, the pusher head 4 comprises an inlet orifice 41 extending axially along the axis X 1 and an outlet orifice 42 extending radially to said axis X 1 which is aligned with the spray port 27 of the protective housing 20. The inlet port 41 and the outlet port 42 of the pusher head 4 are fluidly connected through a conduit, preferably at a right angle. In this example, the pusher head 4 has, at its outlet port 42, a spray nozzle. According to the present invention, the pusher head 4 is not replaced when replacing the cartridge 7, which allows to benefit from a quality pusher head 4 whose vaporization is optimal and improved aesthetic appearance.

Preferably, the pusher head 4 comprises, at its inlet orifice 41, a connection housing 43 adapted to cooperate with a perfume cartridge 7 in the axial direction X1. In this example, the connection housing 43 having a lower portion and an upper portion, the diameter of the lower portion is greater than the diameter of the upper portion. In other words, the connection housing 43 comprises an annular groove adapted to cooperate with a cartridge 7 comprising an annular shoulder, which is particularly advantageous for allowing tight cooperation and optimum centering between the cartridge 7 and the pusher head 4 In other words, contrary to the prior art in which the cartridge included an entire dispensing pump, the present invention proposes to divide the dispensing pump into two removable parts in order to limit the cost of dispensing. a cartridge, and, secondly, to provide a pusher head 4 of improved design. Moreover, such a two-part design makes it possible to limit the risk of involuntary distribution 10 as will be detailed later. Preferably, the pusher head 4 also comprises sealing means interposed between the connection housing 43 and a connection head 83 of the cartridge 7, the sealing means being able to be integrated in the connection housing 43. For example, the connection housing 43 and the connection head 83 have complementary shapes so as to limit any risk of leakage. The presence of a relief and / or a surface condition on the connection housing 43 and / or the connection head 83 improves the sealing. Preferably, the radial clearance between the connection housing 43 and the connection head 83 is of the order of a few micrometers in order to seal the assembly while remaining removable. In this example, the connection head 83 is able to fit tightly into the connection housing 43. In other words, after insertion, the cartridge 7 is secured to the pusher head 4. The pusher head 4 is adapted to translate axially along the axis X1 between an inactive high position, in which no vaporization occurs, and an active low position in which a volume of liquid is vaporized. In a preferred manner, the pusher head 4 is made of plastic, but it is obvious that other materials may be suitable. As previously presented, the spraying means also comprise a spring tube 5 supporting the pusher head 4.

Referring again to Figures 4, 7 and 8, the spring tube 5 extends axially along the axis X1 and is adapted to receive in its interior cavity a perfume cartridge 7. The spring tube 5 is adapted to compress elastically along the axis X1 in the manner of a spring. In this example, with reference to FIG. 4, the spring tube 5 comprises an upper support part 51, an intermediate compression part 52 and a lower connection part 53. The spring tube 5 further comprises an upper face and a 10 in this example, the section of the lower connecting portion 53 is larger than the section of the upper support portion 51 to prevent movement of the cartridge 7 through the upper opening of the spring tube 5.

In this example, the lower connecting portion 53 of the spring tube 5 is integrally mounted in the hollow main body 21 of the protective housing 2, in particular by means of clips. The compression intermediate portion 52 comprises a plurality of circular rings 20 connected by elementary pins so as to allow compression of said spring tube 5 along the axis Xl. Nevertheless, it goes without saying that other means of elastic compression could be suitable, for example, turns. In this example, the spring tube 5 is adapted to compress on a first stroke Cl, of the order of 2 mm, following a low pressure of the order of 400 g / cm 2 and on a second stroke C2 25 of the order of 1.5 mm, following a higher pressure of the order of 2 kg / cm 2. In other words, the pressure must be increasing to compress the spring tube 5. The adjustment of the races C1, C2 of the spring tube 5 are advantageously adjusted by modifying its compression intermediate portion 52.

The lower connecting portion 53 of the spring tube 5 is removably mounted on the base 22 of the protective housing 20 via connecting means which are preferably in the form of a balancer connection 54. However, it goes without saying that other means could be suitable, for example, a screw connection. In the mounted position, the spring tube 5 is integral with the base 22. As illustrated in FIG. 7, the upper support part 51 of the spring tube 5 is adapted to connect firmly to the pusher head 4 so that it it is mounted resiliently with respect to the protective housing 20 via the spring tube 5. Furthermore, the upper support portion 51 has a shape complementary to that of the actuating button 26 to improve the transmission of the axial efforts. In particular, the spring tube 5 comprises an axial bearing surface 55 as illustrated in FIG. 7 to receive a pressure force applied to the actuating button 26. Thanks to the spring tube 5, the pusher head 4 is mounted so that elastically with respect to the base 22 to allow the pusher head 4 to go up axially to its inactive high position following its compression in the active down position. According to a preferred aspect, with reference to FIG. 8, the spring tube 5 further comprises a flexible tongue 56 projecting towards the axis X 1, preferably curved, adapted to radially constrain a cartridge 7 in order to press it into the tube spring 5 and thus eliminate any radial play. In this way, the cartridge 7 is blocked and is not likely to move during the transport of the vaporizer 1. Referring to Figure 11, there is shown a removable shell 6 adapted to be mounted on a protective housing 20 Such a removable shell 6 is advantageous as such since it allows to deform freely in case of deformation of the protective housing 20, in particular, because of thermal expansion. Such deformation also facilitates mounting by allowing radial play, which is particularly advantageous when the protective housing 20 has suffered shocks.

The removable shell 6 has a one-piece body 60 which has a cylindrical liner shape extending along the axis X6 which comprises an upper opening 6A and a lower opening 6B. The lower opening 6B extends in a plane transverse to the axis X6 while the upper opening 6A extends in an oblique plane 3034293 14 to the axis X6, preferably, making an angle of between 350 and 550 with the plane of the lower opening 6B. Still with reference to FIG. 11, the removable shell 6 includes a rear vertical slot 61, connecting the upper opening 6A to the lower opening 6B, and a front vertical notch 62 extending downwardly from the top opening. 6A to allow the vaporization of perfume from the spray orifice 27. In other words, the rear vertical slot 61 is diametrically opposite to the vertical notch before 62. The removable shell 6 has a wall of constant thickness. Preferably, its upper edge is bevelled so as to cooperate with the beveled lower edge of the upper abutment 25 of the protective housing 20, which promotes cooperation and improves aesthetics, the removable cover 6 being advantageously integrated into the protective case 20. Due to its shape, the removable shell 6 can slide on the hollow body 20 of the protective casing 2 so as to protect it, in particular, shocks. Such a removable shell 6 is preferably made of a semi-rigid material, for example, made of plastic material in order to be easily washed. The rear vertical slot 61 advantageously makes it possible to give the removable shell 6 a flexibility in the radial direction. Thus, if the protective housing 20 is heated and expands thermally, the removable shell 6 is deformed because of its flexibility, without risk of rupture. Referring now to FIG. 12, there is shown a perfume cartridge 7 to be mounted in a portable refillable vaporizer 1 as previously discussed. The cartridge 7 comprises a perfume storage tank 70 extending axially along an axis X7 and comprising an upper dispensing opening 30 in which a dispensing pump 8 is mounted. In this example, the storage tank 70 has a capacity of between between 1 ml and 7 ml, preferably between 4.6 ml and 5.4 ml, more preferably equal to 5 ml. The storage tank 70 is in the form of a cylindrical bottle only opened by its upper opening. Preferably, the outer diameter of the reservoir 70 is substantially smaller than the inner diameter of the spring tube 5 to allow optimal guidance. In this example, the storage tank 70 is made of plastic or glass.

The cartridge 7 has a vertical length, preferably between 60 mm and 70 mm, which is less than the length between the connection housing of the pusher head 4 of the protection base 22. In other words, when the cartridge 7 is mounted integrally with the pusher head 4, the latter is spaced from the protection base 22 of an operating clearance J of the order of 2 mm as illustrated in Figure 14. Referring to Figures 12 and 13, the dispensing pump 8 comprises a pump body 80 and a dispensing tube 81 which is slidably mounted in said pump body 80 and which includes a vertically extending dispensing orifice 82. The dispensing pump 8 further comprises a connection head 83, mounted on said dispensing tube 81, and an elastic spring 84 mounted between said connection head 83 and said pump body 80 so as to allow the dispensing of a dispenser. perfume volume through the dispensing orifice 82 during the vertical downward movement of the connection head 83. Thus, the connection head 83 is adapted to translate along the axis X7 between an inactive high position and a low position. active. In this example, the elastic spring 84 is mounted externally to the dispensing tube 81, which reduces the cost of the cartridge 7.

The connection head 83 is cylindrical and has a central bore, adapted to internally receive said dispensing tube 81. Such a cylindrical connection head 83 is particularly advantageous since it can be introduced in any orientation in the spray 1.

In this example, with reference to FIG. 13, the connection head 83 has an annular shoulder 86 adapted to form a bearing surface in order to axially move the connection head 83 along the axis X7. The connection head 83 thus defines an upper part and a lower part, the diameter D2 of the lower part 3034293 being greater than the diameter D1 of the upper part. Thus, the connection head 83 advantageously forms a means for centering the cartridge in a vaporizer 7. Preferably, the upper diameter D1 is of the order of 2 mm to 4 mm while the lower diameter D2, corresponding to the the annular shoulder 86 is between 3 mm and 6 mm. Such dimensions make it possible to ensure a compromise between the mechanical strength during a pressure and a limited manufacturing cost. The dispensing pump 8 is configured to dispense a liquid volume of between 0.05 ml to 0.15 ml, preferably 0.05 ml for each movement of the connection head 83 of the cartridge 7. Thus, a Cartridge 7 ensures about a hundred sprays. The elastic spring 84 of the cartridge 7 is configured to keep the connection head 83 in the inactive high position. For this purpose, the elastic spring 84 is calibrated so as to allow a displacement of the connection head 83 in the active low position only if a downward axial force is applied to the connection head 83. In this example, a pressure of 1 kg / cm 2 on the connection head 83 allows distribution by moving the connection head 83 by 1.5 mm.

In other words, the elastic spring 84 keeps the connection head 83 in the inactive high position to prevent the cartridge 7 from being emptied involuntarily. In addition, even if the user inadvertently applies a downward axial pressure on the dispensing pump 8, no dispensing occurs as, on the one hand, the dispensing orifice 82 is susceptible to it is obstructed in the event of pressure 25 and, on the other hand, the elastic spring 84 keeps the connection head 83 in the inactive high position. Preferably, in order to avoid any risk of unintentional dispensing, the dispensing pump 8 is protected by a cap 9 which is removably mounted on the upper part of the tank 70 as illustrated in FIG. , the cartridge 7 comprises a module for recharging its reservoir 70.

A tank 70 containing perfume has been presented, but the invention applies to any alcoholic product, in particular an alcoholic product, for example ethanol, for cleaning the internal duct of the pusher head 4.

A method of mounting a perfume cartridge 7 in a vaporizer 1 will now be presented. First, the actuating button 26 is mounted in the main hollow body 21, then the pusher head 4 and the spring tube 5 are successively introduced into the main hollow body 21 by its lower opening. In this example, the spring tube 5 is integrally mounted with the main hollow body 21 by means of clips or elastic tongues. In other words, the spring tube 5 holds the actuating button 26 and the pusher head 4 in the inactive high position.

Then, as illustrated in FIGS. 5 and 6, the lower part of the cartridge 7 is inserted into the housing 23 of the base 22 so that the axis of the vaporizer X1 is coaxial with the axis of the cartridge X7. Then, the cartridge 7 is inserted axially into the spring tube 5 until the connection head 83 of the cartridge 7 snaps tightly into the connection housing 43 of the pusher head 4. After interlocking, the cartridge 7 and the pusher head 4 are integral in axial translation. The protective casing 20 is then closed by securing the base 22 to the spring tube 5.

In this example, the lower portion 53 of the spring tube 5 cooperates by a bayonet connection 54 with the base 22 to be integral. Thus, the cartridge 7 is axially locked in the spring tube 5. Advantageously, the flexible tongue 56 of the spring tube 5 makes it possible to cancel any radial clearance of the cartridge 7 in the spring tube 5, which prevents any premature wear of the makes vibrations. In this position, the connection head 83 of the cartridge 7 is in the high idle position. The lower part of the cartridge 7 is integrally mounted to the pusher head 4, which is spaced from the protection base 22 by an operating clearance J of the order of 2 mm as illustrated in FIG. 14 .

In a preferred manner, a removable shell 6 is mounted on the hollow main body 21 when it is connected to the base 22 as shown in FIG. 1. Such a removable shell 6 has an outer surface that can be customized.

Following its assembly, the vaporizer 1 is in an inactive position, the pusher head 4 of the vaporizer 1 and the connection head 83 of the cartridge 7 being respectively held in inactive high positions by the spring tube 5 and the elastic spring 84 .

The use of a vaporizer 1 in which is mounted a cartridge 7 will now be presented with reference to Figures 14 and 15. The vaporizer 1, because of its reduced dimensions, can be advantageously stored in a purse or a pouch. In addition, since it has a one-piece structure, that is to say without a cap, it can not disassemble, which is very advantageous. Although the actuating button 26 can be directly pressed, the risk of unintentional spraying is very low. Indeed, its surface is limited since it does not project from the housing 20. Only a localized and therefore deliberate pressure makes it possible to dispense perfume. In addition, the pressing force must be sufficient so that the actuating button 26, resting on the pusher head 4 opposes, on the one hand, the elasticity of the spring tube 5, and on the other hand to the elasticity of the elastic spring 84 of the cartridge 7.

To perfume, it is sufficient for the user to grasp his vaporizer 1 by hand and to press, for example with his index finger, the actuating button 26 in order to move it axially downwards as illustrated in FIG.

The pressure force P causes the actuating knob 26 to move and a support, according to the axial bearing surface 55, on the spring tube 5 which compresses on a first stroke Cl until the cartridge 7 enters In fact, as the pusher head 4 is secured, on the one hand, to the upper part of the spring tube 5 and, on the other hand, to the cartridge 7, a displacement of the part 3034293 19 upper 51 of the spring tube 5 causes a displacement of the cartridge 7 downwards, which cancels the functional clearance J. During this first race Cl of the order of 2 mm, only the spring tube 5 is compressed, the elastic spring 84 of the cartridge 7 not being requested. No perfume distribution occurs during the first race Cl, which forms a safety against inadvertent dispensing. Thus, no cap is necessary for the vaporizer 1, which is advantageous. The pressure force P of the operator required for the first stroke C1 is small, of the order of 400 g / cm 2, which makes it possible to damp the pressure force P without giving the user a feeling of blocking of the actuating button 26. To allow dispensing, the pressure P of the user must be greater in order to oppose both the elastic force F5 of the spring tube 5 and the elastic force F84 of the spring spring 84 on the second race C2. In this example, to allow dispensing, the actuating button 26 must be moved on the order of 1.5 mm with a pressure force P greater than 3 kg / cm 2 to oppose the elastic force F5 of the tube spring 5, about 2kg / cm2, and the elastic force F84 of the elastic spring 84, about 1kg / cm2. In other words, the total stroke of the actuating button 26 is 3.5 mm and requires a pressure P of the order of 3.5 kg / cm 2. At the end of the stroke, the actuating button 26, the pusher head 4 and the connection head 83 are all in the active down position. In other words, the spring tube 5 calibrates the force required to apply to the connection head 83 of the cartridge 7 to distribute a volume of perfume. Thanks to the spring tube 5 and the spring 84, the pressure force P received by the connection head 83 is damped and calibrated so that the connection head 83 is optimally moved to its active down position. to release a volume of perfume. Following the release, a volume of perfume is distributed axially through the dispensing orifice 82 of the cartridge 7 to enter the inlet port 41 of the pusher head 4 and radially out through the spray orifice 27 of the vaporizer 1 as illustrated in FIG.

Thus, even if the pressure force P of the user is excessive, the vaporizer 1 makes it possible to compensate for this force to allow optimal distribution, which limits the wear of the vaporizer 1.

Replacing an empty cartridge 7 with a new cartridge 7 is particularly simple. It is sufficient for the user to open the protective housing 20 by separating the base 22 from the hollow main body 21. By removing the base 22, the user advantageously removes the empty cartridge 7 which is mounted in the housing 23 of the base 22 without affecting the spring tube 5 or the pusher head 4 which remain 10 housed in the hollow main body 21. Such a withdrawal is all the easier as the connection head 83 of the cartridge 7 is cylindrical. It then suffices for the user to remove the empty cartridge 7 from the connection housing 43 and to replace it with a new cartridge 7 which is mounted in place of the empty cartridge 7. The base 22, equipped with its new cartridge 7, can then be introduced into the spring tube 5 and connected to the hollow main body 21 in order to close the protective housing 20. The introduction of the new cartridge 7 is particularly simple since the connection head 83 makes it possible to center the cartridge 7 in the pusher head 4. Advantageously, thanks to the invention, the replacement of a cartridge 7 is performed under optimal hygiene conditions, the user not being forced to manipulate the head connection 83 of the cartridge 7 or the pusher head 4 of the vaporizer 1 through which the liquid perfume passes. Advantageously, it is not necessary to replace the pusher head 4 which remains connected to the vaporizer 1. In addition, the cartridge 7 can be of simple design, which reduces its manufacturing cost. Similarly to the replacement of a cartridge 7, the replacement of a removable shell 6 is easy. It is sufficient for the user to open the protective housing 20 by separating the base 22 from the hollow main body 21. Following removal of the base 22, the removable shell 6 can then be slid down to remove it. the hollow main body 21. A new removable shell 6 can then be slid on the hollow main body 21 in place of the old removable shell 6. The vertical tongue 28 of the hollow body 21 can guide the removable shell 6 when the his withdrawal and his introduction. In addition, the radial flexibility of the shell 6 makes it possible to overcome the deformations of the protective housing 20. The connection of the base 22 to the hollow main body 21 makes it possible to constrain the removable shell 6 against the upper abutment 25, the hull removable 6 being then positioned intimately on the protective housing 20 in a reduced time. 10
