Definitions
- the present invention relates to a fluid dispenser comprising a fluid reservoir formed with an opening, a dispensing member formed with a body and a fixing member for fixing the body in the opening.
- This type of dispenser is frequently used in the field of perfumery, cosmetics or even pharmacy to distribute fluid products such as perfumes, lotions, creams, gels, liquid or even powdered pharmaceutical products.
- a well-known configuration implements a ring forming an external skirt provided internally with a hooking head or with a continuous hooking cord. The skirt can be continuous or split so as to form legs separated by slits.
- the opening is in the form of a neck defining an external wall formed with a reinforcement delimited at its lower part by an inward shoulder.
- the attachment heads or the attachment cord are intended to come into engagement with this shoulder inwards and the skirt is then locked in position by a covering band which comes to surround the skirt.
- a variant even provides for using the lower edge of the covering band to deform by creep the lower part of the skirt so as to deform it inwards under the reinforced part of the neck.
- JQ also exists other types of fixing member allowing fixing inside the opening.
- More elaborate techniques provide one or more recesses inside the internal wall of the opening intended to receive protruding parts of the fixing member. It is then an internal click.
- this technique it is necessary to exert a relatively strong thrust on the fixing member, or even sometimes on the dispensing member, to embed the fixing member inside the opening.
- the fact of embedding or force fitting the fixing member in the opening creates an overpressure inside the tank, which can be harmful in the case where the tank has a very low capacity.
- the present invention aims to remedy the aforementioned drawbacks of the prior art by defining a fixing member inside the opening which requires almost no pushing force on the fixing member and which does not create overpressure inside the tank.
- the attachment is very secure.
- the present invention provides a fluid dispenser comprising a fluid reservoir formed with an opening, the opening being formed by a neck comprising an upper end and an internal wall defining a narrowed opening section nearby.
- a dispensing member formed with a body, a fixing member for fixing said body in the opening, said fixing member comprising a skirt intended to come into engagement in the opening and a sleeve intended to come into engagement around the body, characterized in that the body forms a cam section to deform the skirt towards the outside in pressed contact in the opening, the skirt comprising a sealing zone coming in final position in leaktight contact with the narrowed opening section and a fixing zone coming, in posi tion, in close contact with the hollowed out section.
- the body of the fixing member serves as a tool for bringing the skirt into the final mounting position.
- the skirt cooperates with the opening at the level where it is in pressed contact, and preferably does not extend below the opening inside the tank.
- the opening is formed by a neck defining an internal wall
- the skirt cooperates with this internal wall and does not extend below the neck at the level where the neck is connected to the body of the reservoir.
- the body comprises an enlarged section on which the sleeve comes into tight sealing engagement in the final mounting position.
- the body comprises an intermediate section situated above the cam section and below the enlarged section, the skirt coming into tight engagement with this intermediate section in the final mounting position, the sleeve being engaged with this intermediate section. before the skirt engages the cam section.
- the body comprises a reduced section located below the cam section, the skirt being engaged with this reduced section when the sleeve is engaged with the intermediate section.
- the sleeve is initially engaged and momentarily held in position at the intermediate section of the body, and is then moved along the body so as to engage on the enlarged section, with which it defines a tight tight grip corresponding to the final mounting position.
- the skirt is initially engaged on the body at the reduced section, and is then moved along the body passing over the cam section to reach the final mounting position engaged with the intermediate section.
- the cam section and the intermediate section form only one profiled section, for example in a frustoconical manner.
- the opening may have a substantially cylindrical inner wall.
- the part of the skirt which comes into pressed contact with the cylindrical internal wall of the opening ensures both sealing and fixing.
- the skirt forms legs separated by slots.
- the tabs formed by the skirt only guarantee the fixing, and the seal is ensured by the upper part of the skirt which is not split but which is nevertheless deformed against the internal wall of the opening.
- the body forms an upper collar under which the sleeve abuts in the final position.
- the sleeve comprises an internal wall forming a retaining ring adapted to come into tight engagement with the intermediate section to hold the fixing member in place on the body during its introduction into the neck, before reaching its final mounting position.
- the skirt may include an internal wall formed with a cam ring intended to come into engagement with the cam section.
- the skirt includes a lower lip in contact with the body. In this case, the skirt can be in contact with the intermediate section only with the cam ring and the lower lip.
- the fixing member comprises a support flange intended to come to bear freely on the opening without force fitting.
- the dispensing member can be pre-engaged inside the fixing member with the sleeve located at the intermediate section and the skirt at the reduced section. This sub-assembly can then be easily introduced into the opening without tight contact or friction until the support flange comes to bear on the opening. Thus, no overpressure is created inside the tank.
- FIGS. 1 to 3 represent three successive stages of mounting a dispenser according to a first embodiment of the invention
- FIG. 4 is an enlarged view of a detail of FIG. 3, and
- FIGS. 1 to 4 are views similar to Figures 1 to 3 for a second embodiment of the invention.
- the partially represented distributor includes three constituent elements, namely, a reservoir 1 forming a neck 10 which defines an opening which communicates with the interior of the reservoir, a dispensing member 2 which may be a pump or a valve, and a fixing member 3 making it possible to fix the dispensing member 2 in the neck 10.
- the reservoir 1 can typically be a glass reservoir which is used as a bottle, particularly in the field of perfumery.
- the neck 10 of this reservoir comprises an upper end wall 12 of annular shape which can advantageously be provided with a sealing profile 122.
- the neck 10 further comprises an internal wall 11 which is connected to the end wall 12 by an input chamfer
- the internal wall 11 forms a narrowed opening section 111 which can advantageously be substantially cylindrical. Below this narrowed opening section 111, the internal wall 11 forms a hollowed out section 112 whose internal diameter is greater than that of the narrowed opening section 111. Below the hollowed out section 112, the internal wall 111 forms a rounded section 113 which is connected to the internal wall of the shoulder which makes it possible to connect the neck 10 to the body of the reservoir (not shown). The diameter of the section 113 is less than that of the section 112, and advantageously also less than that of the section 111. This is a completely conventional design for a glass tank neck produced by blowing.
- the dispensing member 2 comprises a body 20 inside which an actuating rod 21 is movable by pressing on a pusher 22 mounted at the upper end of the rod 21.
- the body 20 defines at its lower end a sleeve inlet 201 which defines an inlet allowing the interior of the reservoir to communicate with the interior of the body 20.
- the body Above the sleeve 201, the body forms a transition section 202 which widens outwardly frustoconical and / or cylindrical. Above this transition section 202, the body forms a reduced cylindrical section 203.
- This section 203 is connected upwards to a cam section 204 which is here of frustoconical shape by flaring outwards and towards the high.
- the body forms a cylindrical intermediate section 205. Beyond this section 205, the body forms a junction section 206 which flares here frustoconically outward and upward. Beyond this junction section 206, the body forms an enlarged section 207 which is advantageously of cylindrical shape. Finally, beyond this expanded section
- the fixing member 3 is here in the form of a ring comprising a skirt 31 in the lower part, a sleeve 32 in the upper part and a support flange 33 which extends radially outwards at the level where the sleeve 32 is connected to the skirt 31.
- the skirt 31 can be perfectly continuous, but preferably it is split over at least part of its height so as to define a solid upper crown 313, from which extend legs 314 separated by slots 315, as this is visible from Figures 1, 2 or 3.
- the skirt, at the level where it forms the legs 314 defines an external wall forming an outer bead 312.
- the diameter of the skirt at the bead 312 is greater than that of the skirt at the level of the continuous upper crown 313.
- the skirt 31 always at the level of the legs 314 defines an internal wall forming at its lower end a lip 316.
- the internal wall of the skirt 31 forms a rod 311 which can for example be in the form of a series of protuberance formed on each leg 314 and arranged along a circular line. It is the same for the lip 316 which can also be in the form of a series of reinforcements arranged at the lower ends of the legs 314. Of course, it is also possible to use a continuous skirt with a continuous lip 316 as well than a continuous rod 311.
- the rod 311 has a cam function as will be seen below.
- the sleeve 32 includes a free annular upper end 322 as well as an internal wall defining a retaining ring 321.
- the support flange 33 advantageously forms an annular housing 331 intended for the reception of the sealing profile 122 formed by the upper end wall 12 of the neck 10.
- FIG. 1 Reference will now be made to FIG. 1 to explain how the fixing ring 3 is initially engaged on the body 20 before mounting the ring in the neck 10.
- the sleeve 32 is engaged on the intermediate section 205 of the body 20.
- the retaining ring 321 is in tight engagement with the intermediate section 205. Consequently, the internal diameter of the ring 321 has a diameter slightly less than the external diameter of the section 205, while the rest of the internal wall of the sleeve 32 may have an internal diameter slightly greater than the external diameter of the section 205.
- the sleeve 32 is in contact with the section 205 only at the level of the retaining ring 321.
- the skirt 31 which begins below the support flange 33, extends partially at the intermediate section 205, but also at the cam section 204 and the reduced section 203. It can be seen in FIG. 1 that the tabs 314 formed by the skirt extend entirely at the level of the cam section 204 and of the reduced section 203.
- the cam ring 311 is situated at the level of the cam section 204, without however coming into contact with it. As for the lower lip 313, it comes into contact, advantageously not tightening, with the reduced section 203. Only the continuous upper crown 313 is located at the level of the intermediate section 205, without however coming into contact with the section 205.
- the internal wall of the crown 313 extends in the extension of the internal wall of the sleeve 32 which is in contact with the intermediate section 205 only at the level of the retaining ring 321. It is in this initial position before mounting that the fixing ring 3 is engaged on the body 20 of the dispensing member.
- the dispensing member 2 with its fixing ring thus forms a momentary unitary unit which is engaged in the neck 10 so as to make the skirt 31 penetrate the neck 10 until the support flange 33 comes rest on the upper end 12 of the neck.
- the maximum external diameter of the skirt 31, situated at the level of the external bead 312 is equal to or slightly less than the minimum internal diameter of the neck situated at the level of the reduced section 111.
- the skirt 31 can be engaged in the neck 10 without excessive friction or effort.
- the bead 312 of the skirt 31 has an external diameter very slightly greater than the internal diameter of the reduced section so that the skirt can be engaged with very reduced pressure inside the neck 10.
- the third mounting step consists in exerting a pressing force F on the dispensing member, that is to say on its pusher or on the flange 208.
- the pump body 20 moves inside the fixing ring 3. Firstly, the cam ring 311 comes into contact with the cam surface 204 of the body 20.
- the internal diameter of the sleeve 32 is slightly less than the external diameter of the enlarged section 207.
- the lip 316 located initially at the level of the reduced section 203 moves on the cam section 204 to arrive at the level of the intermediate section 205
- the passage of the lip 316 from the reduced section 203 to the intermediate section 205 also generates a deformation by expansion of the skirt, which has the effect of further increasing the external diameter of the skirt, particularly at its bead 312
- the final position is reached when the upper end 322 of the sleeve 32 abuts under the flange 208 as shown in FIG. 3 and FIG. 4.
- the skirt 31 is entirely situated at the level of the intermediate section 205. It may also be noted that the internal wall of the skirt 31 is in contact with the section 205 only at the level of the cam ring 311 and the lower lip 316 Everywhere else, there remains a space between the skirt and the intermediate section 205. Thanks to the cam ring 311 and to the lower lip 316, the expansion of the skirt towards the outside to come into tight and tight contact with the internal wall.
- the neck thus operates in two stages, namely an initial stage during which the cam ring 311 engages the cam section 204 to finally reach the level of the intermediate section 205, and a second stage during which the lip 316 follows the same path.
- the cam ring 311 rather has the effect of expanding the skirt at its crown 313 and the upper end of the legs 314 while the lip 316 rather has the effect of expanding the lower end of the legs.
- the bead 312 which is located between the rod 311 and the lip 316 undergoes expansion in two successive stages generated by the raising of the cam rod 311 then of the lip 316 on the cam section 204 to reach to the intermediate section 205.
- FIGS. 5 to 7 illustrate an alternative embodiment in which the dispensing member 2 can be strictly identical to that of FIGS. 1 to 4.
- the body 20 can be on the same floor way, or at least realized with a reduced section, a cam section, an intermediate section and then an enlarged section.
- the reservoir 1 here comprises a neck 10 ′ having an internal wall 11 which is substantially cylindrical over the entire height.
- the upper end wall of the neck 10 ′ may be identical to that of the previous embodiment. There is therefore no hollowed out part at the level of the internal wall 11 'of this neck 10'.
- the fixing member 3 ' may include an upper sleeve 32 and a support flange 33 strictly identical to those of the previous embodiment.
- the skirt 31 ' differs from that of the previous embodiment in that it comprises a substantially cylindrical outer wall and an inner wall forming an upper cam shoulder 311' located just below the cam section 204 in position pre-assembly initial. This is visible in Figures 5 and 6.
- This cam shoulder 311 ' will play the same role as the cam ring 311 of the previous embodiment.
- the skirt 31 ' can be engaged inside the neck 10' without exerting considerable force.
- the external diameter of the skirt 31 ' is somewhat less than the internal diameter of the internal wall 11' of the neck 10 '.
- the skirt 31 ' can be placed inside the neck 10' until the support flange 33 comes to bear on the upper end of the neck 10 '.
- the cam shoulder 311 ' is then still still located below the cam section 204.
- the cam shoulder 311' will engage with the cam section 204 then go back to the intermediate section 205.
- the sleeve 32 will go up on the enlarged section 207 as in the previous embodiment until it comes into abutment with its upper end under the flange 208 of the body 20.
- skirt 31 ' Being given that the skirt 31 'is also produced with a lower lip 316, this will also go up on the cam section 204 to reach the intermediate section 205. The raising of the lip 316 also generates a dilation which improves or completes the tight tight grip of the skirt 31 'against the wall 11'.
- the fixing and sealing of the fixing member 3 ′ is only carried out by a tight tightening cylinder against cylinder.
- the flared part 112 formed by the internal wall 11 of the neck 10 still has the effect of making a hooking or blocking below the narrowed opening section 111. This was all the more favored by the presence of the peripheral bead 312.
