Definitions
- Fixing member for fixing a dispensing member to a reservoir opening and dispenser comprising such a fixing member
- the present invention relates to a fixing member for fixing a dispensing member to an opening of a reservoir, as well as a distributor using such a fixing member.
- the fixing member generally comprises receiving means, for example by snap-fastening, intended to receive the dispensing member.
- the fixing member may comprise a substantially cylindrical skirt intended to be forcibly engaged in the opening of the reservoir to make a tight tight contact there.
- This type of fixing member is frequently used in fluid dispensers in the field of perfumery, cosmetics or even pharmacy.
- Document EP-0 823 288 describes a fixing member of this type.
- the skirt of the fixing member can engage inside or outside the opening formed by the reservoir.
- the skirt In the version where the skirt is forcibly engaged inside the tank, it includes a continuous cylindrical upper part and a vertically grooved cylindrical lower part. This vertically grooved part extends to the lower end of the skirt.
- the air present inside the tank can escape through the vertical grooves.
- the air from the tank escapes therefrom until the continuous cylindrical upper part comes into tight tight engagement in the opening of the tank. From this moment, the inside of the tank is sealed from the outside.
- the final assembly is obtained when a radial flange formed by the skirt comes to bear on the upper end of the opening of the reservoir.
- a comparable venting system is described in document EP-0 628 355, in which a fixing member supporting a pump comprises a skirt formed with a continuous cylindrical upper section below which are formed a series of vertical grooves intended to allow the venting of the tank before the final mounting of the fixing member.
- the fixing member of document EP-0 823 288 is more particularly intended to be mounted on small capacity tanks made of glass. In general, these are sample distributors.
- the problem with this type of glass vial is that the tolerance on the internal diameter of the vial is relatively large. Therefore, it may happen that the vertical grooves formed on the lower part of the skirt are completely crushed when the internal diameter of the opening of the vial is reduced. To overcome these drawbacks, the depth of the grooves can be increased, but this requires forming the skirt with a greater wall thickness, which is hardly compatible with the samples for reasons of size.
- the present invention aims to remedy this aforementioned drawback of the prior art by defining a fixing member implementing another type of venting.
- the present invention proposes that the skirt be formed with at least one vent hole passing through the thickness of the skirt.
- the inside of the skirt located inside the tank can communicate with the outside as long as a seal is not formed above the vent hole.
- the flow of air from the reservoir no longer takes place along the external wall of the skirt, but through the interior of the skirt through the through vent hole.
- the hole is formed below an upper section of increased diameter intended to come into tight tight contact in the opening. It is precisely this upper section of increased diameter which will cut the communication between the vent hole and the exterior at the end of mounting of the fixing member in the opening of the tank. Indeed, it does not matter that a seal is already made below the vent hole, since it does not prevent the exit of air from the tank through the vent hole.
- the hole is formed at a middle section of increased diameter intended to come into tight tight contact in the opening.
- a seal can be directly formed around the vent hole where it opens onto the outer wall of the skirt.
- the diameter of the middle section can be identical to that of the upper section, but one can also provide a middle section having a diameter which is less than that of the upper section, or at least less than part of the upper section.
- the hole is formed above a lower section comprising a portion of increased diameter intended to come into tight sealing contact in the opening. Thus, a seal can be achieved by pressing contact below the section where the vent hole is formed.
- the lower section can have a constant diameter so as to form a cylinder, but it can also have a variable diameter of which at least a part can come into tight tight contact in the opening.
- the sealed contact made at the level of the lower section does not cut the communication which exists between the tank and the exterior through the vent hole.
- the upper section and / or the lower section form (s) a rod projecting outwardly intended to be crushed in the opening of the tank.
- the rest of the upper and / or lower section can also come into tight sealing contact with the internal wall of the opening.
- the tight contact will be stronger at the level of the crushed rod.
- the skirt forms an abutment flange intended to come into abutment contact with the opening. The stop of the flange on the upper end of the opening marks the final mounting position of the fixing member, in which the vent hole is advantageously isolated from the outside by the upper section of increased diameter.
- the upper section is formed with at least one vertical groove, one end of which is intended to communicate with the vent hole when the upper section is in tight contact in the opening of the reservoir.
- the vent hole can still continue to perform its venting function until the upper end of the groove is closed.
- the upper end of the groove extends to the top of the upper section of increased diameter, that is to say just below the stop flange. In this case, the seal can be made against the stop flange.
- the hole is formed at the level of a median section of narrowed diameter intended to remain out of contact with the opening of the reservoir.
- the middle section once engaged inside the reservoir opening, forms an annular which can communicate with the groove advantageously formed at the upper section. This allows the vent hole to be made without the need for orientation, since it is the annular which makes the communication between the vent hole and the vertical groove (s).
- the fixing member forms an internal ferrule against which at least one component of the dispensing member is resiliently biased in the rest position.
- the present invention also relates to a liquid or pulverulent fluid product distributor comprising a reservoir, a distribution member and a fixing member of the invention.
- Figure 1 is a front view of a fixing member according to a first embodiment of the invention
- Figure 2 is a vertical cross-sectional view showing the right part of the fixing member of FIG. 1
- FIG. 3 is a view in vertical cross section through the fixing member of FIG. 1 associated with a dispensing member, during mounting in the opening of a reservoir
- Figure 4 is a view similar to that of Figure 3 with the fixing member in the final mounting position inside the opening of the tank
- Figures 5, 6, 7 and 8 are sectional views vertical transverse skirts of fasteners according to four other embodiments of the invention.
- FIGS. 1 and 2 to explain the structure of a fixing member 100 according to a first embodiment of the invention.
- This fixing member 100 can be made of molded plastic. It generally has a symmetry of revolution around the axis A- A of FIG. 2.
- the fixing member 100 comprises a skirt 110 which is generally cylindrical.
- the skirt 110 is extended upwards by a sleeve 130 which extends substantially in the extension of the skirt 110.
- the fixing member comprises a radial flange 120 which s extends inward.
- the radial flange 120 extends downward, forming a substantially cylindrical crown 140.
- the skirt 110, the flange 120 and the crown 140 define an internal housing 132 whose function will be given below.
- the sleeve 130, the flange 120, the crown 140, the shoulder 150 and the ferrule 160 as well as the upper part of the skirt 110 may be common to all the embodiments of FIGS. 5 to 8.
- the present invention is rather situated at the skirt 110, and more particularly at its lower part.
- the skirt forms a transition section 112 which here has a substantially frustoconical outer wall. Above this transition section 112, the skirt forms a lower section 113 which is here substantially or perfectly cylindrical. Beyond this section 113, the skirt forms an intermediate section 114 at the level of which a vent hole 115 is formed through the thickness of the skirt, as can be seen in FIG. 2.
- the intermediate section 114 is here substantially or perfectly cylindrical and is connected to the lower section 113 continuously. We can even foresee that the external diameters of sections 113 and 114 are identical.
- the skirt forms an upper section 116 which here formed with a rod 1161 which projects radially outward.
- the rod 1161 forms a part of the external wall of the upper section 116, but the remainder of the external wall of the upper section 116 can be substantially or perfectly cylindrical and has an external diameter advantageously identical to those of the intermediate section 114 of the lower section 113. This is clearly visible in FIG. 1. It can thus be said that the skirt forms, beyond the frustoconical section 112, a cylindrical section provided near its upper end with a protruding rod 1161.
- the skirt forms a stop flange 117 which also projects radially outwards. Beyond this flange 117, the skirt forms a housing section 118 which partially forms the housing 132 with the connecting flange 120 and the crown 140.
- the internal wall of the skirt 110 can be substantially or perfectly cylindrical. Reference will now be made to FIGS. 3 and 4 to explain how the fixing member 100 of FIGS. 1 and 2 interacts when it is mounted in the opening of a container or of a reservoir for fixing a dispensing member on The reservoir.
- the container or reservoir 2 defines an opening 20 delimited by an internal wall 21 which is for example substantially or perfectly cylindrical.
- the opening 20 is delimited by an upper edge 22.
- the tank can be a small bottle comprising a cylindrical drum closed by a bottom.
- the dispensing member 3 may be a valve or a pump, as is the case in the example used to illustrate the invention.
- the pump 3 can for example comprise a pump body 30 internally defining a pump chamber provided with an inlet 31.
- a piston 33 mounted on an actuating rod 35 capped with a plunger 36 fitted with a nozzle 37 can slide in the pump body 30 to modify the volume of the pump chamber and thus put the fluid stored in the chamber under pressure before it is discharged through the actuating rod 35 to be distributed at the nozzle 37.
- the body pump 30 may for example include a latching reinforcement 34 located at its upper end.
- This latching reinforcement 34 is intended to come into latched engagement inside the housing 132 formed by the fixing member 100.
- This is only a non-limiting embodiment: of course, it is possible to imagine yet other embodiments for the means for receiving the fixing member to receive the dispensing member 3. However, this is a completely conventional form.
- the fixing member 100 is shown partially engaged inside the opening 20 of the reservoir 2. More specifically, the skirt 110 of the fixing member is already partially engaged inside the opening 20, and already makes tight sealing contact with the internal wall 21 at its lower section 113. To do this, the external diameter of the lower section 113 must be chosen to be equal to or slightly greater than the internal diameter of the internal wall 21.
- the lower end section 111 and the transition section 112 both have diameters much smaller than the diameter of the wall 21, hence the existence of an intermediate space as can be seen. see in Figure 3.
- a sealed annular contact is already made between the fixing member and the reservoir.
- the interior of the tank can still communicate with the outside through the vent hole 115 which is located above the lower section 113.
- the body 30 of the pump 3 must not be in contact with the vent hole 115 of so as to seal it permanently and hermetically. It can therefore be noted in FIG. 3 that there is a free annular space between the body 30 of the pump and the skirt 110.
- the vent hole 115 will be hermetically sealed as soon as the intermediate section 114 has penetrate inside the opening 20. As soon as the hole 115 is closed, the inside of the tank no longer communicates with the outside. The seal produced extends over a cylindrical section covering the lower section 113 and the intermediate section 114. By continuing to push the skirt 110 inside the tank, the upper section 116 will also penetrate inside the tank opening. Therefore, the protruding rod 1161 will be constrained inside the tank by making a very strong tight contact.
- the fixing member 100 is made of a substantially deformable plastic material so that the rod 161 will be partially or entirely crushed against the internal wall 21 of the opening 20.
- the skirt 110 will undergo deformation at level of its internal wall in the form of an annular boss 1163, as shown in FIG. 4.
- the upper section 116 is then substantially or perfectly cylindrical inside the tank.
- the final mounting position is reached when the stop flange 117 comes into stop contact with the upper edge 22 of the tank. This is shown in FIG. 4. It can then be noted that the skirt 110 is perfectly cylindrical externally at the level corresponding to the sections 113, 114 and 116. The sealing is carried out over the entire height of these sections with a more important tightening contact at the level of the crushed rod 1161.
- FIG. 5 represents a second embodiment for a fixing member according to the invention.
- the numerical references of the first embodiment started from 100.
- the numerical references started from 200, and so on for the following three modes.
- This fixing member 200 comprises a skirt 210 defining a lower end section 211 and a transition section 212 which may be strictly identical to those of the first embodiment. It is the same for the stop flange 217 and the housing section 218.
- the lower section 213 and the intermediate section 214 are here also identical to those of the first embodiment, that is to say substantially shaped or perfectly cylindrical with an outside diameter equal to or slightly greater than that of the internal wall 21 of the neck in which the skirt must be engaged by force.
- the upper section 216 is here also substantially or perfectly cylindrical and extends in the extension of the intermediate section 214.
- the sections 213, 214 and 216 form a substantially or perfectly cylindrical section having a substantially constant diameter equal or slightly larger than the internal diameter of the neck opening.
- FIG. 6 shows the skirt 310 of a fixing member 300 which is identical to the previous embodiment in level of section 311, 312, 317 and 318 corresponding respectively to sections 211, 212, 217 and 218 of FIG. 5.
- the lower section 313 forms above the transition section 112 a first substantially cylindrical section 3132 , then a protruding rod 3131 which is extended by another substantially cylindrical section
- the two substantially cylindrical sections 3132 have advantageously the same outside diameter which may be equal to or slightly greater than the inside diameter of the container opening.
- the protruding rod 3131 it is adapted to be crushed against the internal wall 21 of the container, for example generating an internal boss comparable to that shown in FIG. 4 with the reference numeral 1163. Therefore, once the rod 3131 crushed against the internal wall 21, it can return substantially to the same cylinder as that defined by the adjacent sections 3132.
- the lower section forms a third section 3133 whose external diameter is less than that of sections 3132.
- the diameter of this section 3133 is preferably less than the diameter of the internal wall
- the upper section 316 may be identical to that corresponding to FIG. 5 referenced 216.
- the upper section 316 may be substantially or perfectly cylindrical and have an external diameter equal or substantially greater than the internal diameter of the wall 21.
- the external diameter of the sections 3132 and 316 is identical.
- the skirt 410 forms sections 411, 412, 417 and 418 which can be identical to those corresponding to the previous embodiments.
- the lower section 413 can also be formed with a protruding rod 4131 intended to be crushed against the internal wall 21 of the tank.
- the skirt forms the intermediate section 414 at which the vent hole 415 is located.
- the upper section 416 extends over a greater height than in the previous embodiments by forming a substantially or perfectly cylindrical section in the extension of the intermediate section 414 and a projecting rod 4161 located near or just below the flange 417.
- a groove 4162 extends over a part or even the entire height of the upper section 416.
- This groove extends vertically and connects with its lower end the vent hole 415.
- the external diameter of the intermediate section 414 and of the upper section 416 in its cylindrical part is advantageously identical or slightly greater than the internal diameter of the reservoir at the level of the internal wall 21.
- the rods 4131, 4161 they are intended to come into contact press against this internal wall 21.
- a cylindrical seal is produced, but this is interrupted at the level of the groove 4162.
- a complete peripheral seal is produced at the level of the rod 4131.
- a seal can be produced at the level of the flange 417 against which the end edge 22 can come into sealing contact.
- the venting is possible up to the final mounting position, since the groove 4162 makes the vent hole 415 communicate with the outside even when the internal wall 21 is already engaged at the level of the upper section 416. Since the groove 4162 breaks the seal at the upper section 416, this will mainly have a fixing and retaining function. The sealing function but also the fixing function will be ensured by the lower section 413. The groove can, however, stop below the rod 4161, so that the latter will achieve complete annular sealing.
- the last embodiment implements a skirt 510 comprising sections 510, 512, 517 and 518 identical to those corresponding to the previous embodiments.
- the lower section 513 may firstly have a substantially or perfectly cylindrical part whose diameter is equal to or slightly greater than the internal diameter of the wall 21. It is also possible make this lower part of the lower section 513 with an outer diameter less than the outer diameter of the inner wall 21, so that there is no seal at this level. Beyond this lower part, the section 513 can form another upper part whose diameter is less than the diameter of the wall 21.
- the intermediate section 514 can also have a diameter less than the diameter of the internal wall 21. As for the upper section 516, it can first extend in the extension of the section
- part of section 516 is formed with one or more vertical grooves 5162 which extend from the reduced diameter part towards the top without extending to the flange 517.
- the skirt 410 of FIG. 7 can be devoid of a protruding rod.
- the skirt 510 of Figure 8 can be provided with one or even two protruding rod (s).
- the embodiment of Figure 1 can also be provided with a communication groove which extends at the level of section 116. It is also possible reahser one or two section (s) among the lower, middle and upper sections with an external diameter less than the internal diameter of the internal wall 21 of the opening, so that there is no tight contact at the level of this or these section (s). We can even foresee that there is no complete peripheral tight contact at the level of the lower, middle and upper sections. By choosing for example one or more groove (s) sufficiently long (s) and / or sufficiently narrow (s), it is possible both to vent during assembly and to prevent any leakage of fluid product by a phenomenon of capillarity.
