Description

The present 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 the cartridge is housed, 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.

Furthermore, a cartridge is likely to empty accidentally when stored, for example, in a purse, any contact with the push button of the cartridge causing a perfume distribution. In addition, in use, the force applied by a user on the valve of the refillable vaporizer must be calibrated so as to allow a distribution of perfume by the cartridge which is optimal while avoiding an unintended distribution.

Finally, such a vaporizer has a limited life because its outer shell is subjected to shocks that affect its aesthetics. Moreover, the outer casing is likely to get dirty when perfume flows on its housing, which penalizes both the aesthetics of the housing and its hygiene.

GENERAL PRESENTATION OF THE INVENTION

In order to eliminate at least some of these disadvantages, 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 storage tank, the reservoir 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 includes 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 distribution of a volume of alcohol product by the dispensing orifice during vertical downward movement of 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 head of connection 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 connection head, 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 abut 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 further relates to an assembly of a cartridge as presented above, and a portable rechargeable vaporizer comprising:

a protective case, in which is housed said cartridge, comprising a spray orifice,

- Spraying means housed in said protective housing, the spraying means comprising a pusher head having an outlet port aligned with said vaporization orifice and an axial connection housing, into which an inlet port opens, the head connecting the cartridge and the axial connection housing of the pusher head being nested in a sealed and removable manner, 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 aesthetically pleasing pusher head 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 defining an internal cavity for receiving said cartridge, the spring tube being configured to damp the movement of the actuating member during a 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 relative to the axis of the vaporizer so as to provide an optimal pressure surface to the user, and 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 has 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 portion and an upper portion, the diameter of the lower portion 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 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 actuator 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 race, 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 soliciting the connection head of the cartridge.

The invention also relates to a portable rechargeable vaporizer comprising a protective housing comprising a spray orifice and spray means housed in said protective housing, the spray means are adapted to be pressed by a user and comprise a pusher head comprising an inlet port, adapted to connect to a perfume cartridge housed in said protective housing, and an outlet port aligned with said vaporization port, the spraying means also having a spring tube defining an interior cavity adapted to receive said perfume cartridge, the spring tube being configured to dampen the displacement 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 spray against shock and dirt. In addition, the vertical slot allows deformation radial of said shell, which facilitates its mounting if the protective housing is deformed due to shocks 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 sprayer housing.

Preferably, the upper opening extends obliquely with respect to the plane of the lower opening to provide space for ergonomic actuation of the vaporizer. In a preferred manner, the plane of the upper opening and the plane of the lower opening are inclined at an angle of between 35 ° and 55 °.

Preferably, the body comprises a vertical front notch, extending downwardly from the upper opening, to allow the 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 spring tube of the vaporizer. PRESENTATION OF FIGURES

Referring to Figure 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 XI. Subsequently, the vaporizer 1 is presented in a vertical position, the X axis extending vertically from bottom to top, that is from the bottom to the top of the vaporizer 1.

Still as an example, the vaporizer 1 has a vertical length of between 65 mm and 1 30 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 Figures 1 and 2, the vaporizer 1 further comprises a shell 6 adapted to be removably mounted on the protective housing 20 to protect and improve the aesthetics of the vaporizer 1 while allowing the identification of the owner of the vaporizer 1 or the identification of the perfume that the vaporizer 1 dispenses. 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 be presented from now on.

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 illustrated in FIGS. 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 casing 20 as will be shown hereinafter . In this example, the housing 23 is in the form of a vertical cylinder whose bottom face is blind and whose upper face is open, the internal diameter of the cylinder being substantially equal to that of the cartridge 7 as shown in FIG. 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 the 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 of metallic appearance and resistant to the components of the perfume, and an inner part, preferably made of plastic, mounted in said decorative outer portion. Preferably, the housing 23 is made of material from 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, comprises a cylindrical lower portion 24 extending vertically and an upper abutment portion 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 portion 24. Thus, the removable shell 6 is advantageously mounted on the cylindrical lower portion 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 allowing 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 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 XI while the upper opening of the hollow body 21 extends substantially in a plane oblique to the axis XI, preferably, making an angle of between 35 ° and 55 ° 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 the continuity of 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 involuntary dispensing. 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 no dispensing since the upper abutment portion 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. Indeed, such an actuating button 26 allows easy spraying by the user simply using his index.

More preferably, with reference to FIG. 1, the protective housing 20 comprises a vertical mounting tongue 28 projecting radially outwardly from the cylindrical lower portion 24 of the hollow body 2. Such a tongue 28 facilitates the guiding the removable shell 6 during its 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 FIGS. 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 pressure on the cartridge 7 as will be presented by the after.

With reference to FIG. 4, the pusher head 4 comprises an inlet orifice 41 extending axially along the axis XI and an outlet orifice 42 extending radially to said axis XI, which is aligned with the orifice 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 cartridge of perfume 7 according to the axial direction XI. 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 has 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. Otherwise said, unlike the prior art in which the cartridge had a whole dispensing pump, the present invention proposes to divide the dispensing pump into two removable parts to, firstly, to limit the cost of a cartridge and, on the other hand, 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, 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 into the connection housing 43. In this 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 adapted to fit tightly into the connection housing 43. In other words, after introduction, the cartridge 7 is integral with the pusher head 4. The pusher head 4 is adapted to translate axially along the axis XI between an inactive high position, in which no vaporization occurs, and an active low position in which a volume of liquid is vaporized. Preferably, the pusher head 4 is made of plastic but it goes without saying that other materials could be suitable. As previously described, the spraying means also comprise a spring tube 5 supporting the pusher head 4. Still referring to FIGS. 4, 7 and 8, the spring tube 5 extends axially along the axis XI 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 XI 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 bottom face which are open as shown in FIG. 7. In this example, the section of the lower connection portion 53 is larger than the section of the upper support portion 51 to prevent any movement of the cartridge 7 to 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 connected by elementary tenons so as to allow compression of said spring tube 5 along the axis XI. 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 C1, of the order of 2 mm, following a low pressure of the order of 400 g / cm ² and on a second stroke C2 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 casing 20 by means of connection means which are preferably in the form of a bayonet connection 54 as shown in Figure 8. Nevertheless, it goes without saying that other means could be suitable, for example, a connection by screwing. 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 integrally with the pusher head 4 so that it is mounted resiliently with respect to the protective casing 20 by the intermediate 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 axial forces. 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.

With the spring tube 5, the pusher head 4 is resiliently mounted relative to the base 22 to allow the pusher head 4 to return 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 XI, preferably curved, adapted to radially constrain a cartridge 7 so as to press it into the spring tube 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 1 1, 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 the thermal expansions. 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 comprises a one-piece body 60 which has a cylindrical jacket shape extending along the axis X6 which comprises an upper opening 6A e † a lower opening 6B. The lower opening 6B extends in a plane transverse to the axis X6 while the upper opening 6A extends in a plane oblique to the axis X6, preferably, making an angle of between 35 ° and 55 ° with the plane of the lower opening 6B.

Still with reference to FIG. 11, the removable shell 6 comprises a rear vertical slot 61, connecting the upper opening 6A to the lower opening 6B, and a front vertical notch 62 extending downwards from the upper 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 housing 20. Due to its shape, the removable shell 6 can slide on the hollow body 20 of the protective housing 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 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 Figure 12, there is shown a perfume cartridge 7 to be mounted in a portable refillable vaporizer 1 as presented above. The cartridge 7 comprises a perfume storage tank 70 extending axially along an axis X7 and comprising an upper dispensing opening in which a dispensing pump 8 is mounted. In this example, the storage tank 70 has a capacity of 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 opened only 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 separating the connection housing from the pusher head 4 of the protection base 22. In other words, when the cartridge 7 is mounted integrally to the pusher head 4, it is remote 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 distribution tube 81, and an elastic spring 84 mounted between said connection head 83 and said pump body 80 so as to allow the distribution of a volume perfume 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 an active low position. . 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 into the vaporizer 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 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 and 0.15 ml, preferably equal to 0.05 ml for each movement of the connection head 83 of the cartridge 7. Thus, a cartridge 7 ensures about a hundred spraying.

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 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 in the event of pressure being obstructed and, secondly, the elastic spring 84 keeps the connection head 83 in the inactive high position.

Preferably, in order to avoid any risk of inadvertent 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. 12. According to a preferred aspect, the cartridge 7 comprises a module for recharging its reservoir 70. There is shown a reservoir 70 comprising perfume, but the invention applies to any alcoholic product, in particular an alcoholic product, for example ethanol, to clean 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 Figures 5 and 6, the lower portion of the cartridge 7 is introduced into the housing 23 of the base 22 so that the axis of the vaporizer XI is coaxial with the axis of the cartridge X7.

Then, the cartridge 7 is introduced axially into the spring tube 5 until the connection head 83 of the cartridge 7 fits tightly in 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 housing 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 bottom part of the cartridge 7 is integrally mounted to the pusher head 4, the latter is distant from the protective base 22 of an operating clearance J of the order of 2 mm as illustrated in FIG. preferred, a removable shell 6 is mounted on the hollow main body 21 when connected to the base 22 as shown in Figure 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 size, can be advantageously stored in a purse or a pocket. In addition, since it has a monobloc structure, that is to say without a cap, that 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 protrude 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 suffices 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 axially downwards as shown in Figure 15. The pressure force P causes the actuating button 26 to move and a support, according to the axial bearing surface 55, on the spring tube 5 which compresses on a first stroke C1 until the cartridge 7 enters into position. In fact, since the pusher head 4 is integral with the upper part of the spring tube 5 and with the cartridge 7, a displacement of the upper part 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 unintended distribution. 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 low, of the order of 400 g / cm ² , which makes it possible to damp the pressure force P without giving the user an impression 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 elastic spring 84 on the second stroke C2. In this example, to allow dispensing, the actuating button 26 must be displaced 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 / cm ² , and the elastic force F84 of the elastic spring 84, about 1 kg / cm ² . 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 elastic 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 so that 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 compensates 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 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 is then sufficient for the user to remove the empty cartridge 7 from the connection housing 43 and 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 to close the protective housing 20. The introduction of the new cartridge 7 is particularly simple since the connection head 83 can 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 connection head 83 of the cartridge 7 or the head of the cartridge. pusher 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 from the hollow main body 21. A new removable shell 6 can then be slid over the hollow main body 21 in place of the old removable shell 6. The vertical tongue 28 of the hollow body 21 guides the removable shell 6 during its withdrawal and its introduction . In addition, the radial flexibility of the shell 6 makes it possible to offset 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.
