Definitions
- the present invention relates to a retention system comprising a sleeve internally forming retention means and a rod externally forming a retention profile.
- the rod is fixedly and axially engaged in the sleeve with the retention profile engaged with the retention means, so that the rod is integral in axial movement with the sleeve.
- This retention system is used in particular in pumps at the level of the actuating rod, on which a pusher is mounted, which the user can activate by pressing on it with a finger.
- the actuating rod is axially movable back and forth in a pump body 5a against a spring 4a.
- the actuating rod comprises an upper portion on which a pusher is mounted and a lower portion on which a piston 3a is mounted.
- the pump chamber C is formed below the lower portion and the piston 3a.
- the upper portion forms a sleeve 1a and the lower portion forms a rod 2a which is fixedly engaged in the sleeve 1a.
- the piston 3a can slide around the rod 2a and inside the sleeve 1a to open and close an outlet orifice, which communicates with an internal channel 14a formed inside the sleeve 1a.
- the piston 3a comprises a sealing lip 31a engaged in a sealed sliding manner in the sleeve 1a.
- the piston 3a also comprises a contact edge 32a which is urged into sealing contact against a corolla 26a of the rod 2a under the action of the spring 4a.
- the piston 3a associated with the actuating rod and the spring 4a forms the outlet valve of the pump.
- the sleeve 1a of the upper part internally forms retention means 13a and the rod 2a of the lower part externally forms a retention profile 23a.
- the retention means 13a of the sleeve 1a are produced by shoulder sectors separated by passages for the fluid product.
- the retention profile 23a of the rod is produced by an annular shoulder formed below an insertion head 21 a of substantially ogival or pointed shape.
- the insertion head 21 a is engaged in the sleeve 1 a until it comes into contact with the shoulder sectors 13 a of the sleeve 1 a. It is then necessary to exert a very strong axial thrust to pass the insertion head 21 a between the shoulder sectors 13 a. This causes momentary and/or permanent deformations, both at the shoulder sectors and at the insertion head 21 a. This force assembly requires great dimensional precision to ensure tightening and mechanical strength. Very often, the rod 2 a is not immobilized in the sleeve 1 a: a radial clearance remains, which can lead to an offset of the rod 2 a relative to the sleeve 1 a. This is explained by the fact that the insertion head 21a must be large enough to ensure axial attachment, but this size does not allow radial contact to be ensured between the shoulder sectors 13a and the rod 2a below the annular shoulder 23a.
- a solution already envisaged in the prior art and visible in FIG. 1 consists in creating an axial window 27a in the insertion head 21a to give it more elastic deformation capacity.
- this axial window 27a weakens the rod 2a, which can then deteriorate during assembly and/or use.
- This type of retention system with a rod engaged in a sleeve can be found in other configurations, and in particular in a pump, for example at the level of the attachment of the pusher on the actuating rod or at the level of a movable valve member.
- the present invention aims to overcome the drawbacks of the prior art set out above by proposing a new retention system, which requires a lower axial thrust force for assembling the rod in the sleeve. Another aim is to favor elastic deformations and to minimize, or even eliminate, permanent deformations. Yet another aim is to increase the flow section. Finally, the invention also aims to not be constrained to use a very particular type of plastic material, such as PBT, so that the sleeve and the rod can be made with an easily recyclable plastic material, such as PE or PP.
- the present invention proposes a retention system defining a longitudinal axis X and comprising:
- a rod forming externally at least one retention profile, in which the rod is engaged axially along the longitudinal axis X in the sleeve with the retention profile in axial engagement with the shoulder sector, characterized in that at least one of the retention means and the shoulder sector is formed by flexible tabs which extend substantially perpendicular to the longitudinal axis X and which are radially deformable in a plane substantially perpendicular to the longitudinal axis X.
- the flexible legs extend substantially perpendicular to the longitudinal axis X. If the longitudinal axis X can be described as vertical, the flexible legs extend horizontally. Thus, the flexible legs are deformable in a plane perpendicular to the longitudinal axis X.
- the movement of the flexible legs can be compared to that of the blades of a diaphragm: the blades move in a horizontal plane to vary the opening of the diaphragm.
- the flexible legs which move in a horizontal plane relative to the vertical axis X to vary the passage opening of the sleeve and/or reduce the passage diameter of the rod. It can also be said that the flexible legs are radially deformable without an axial component.
- each flexible leg may comprise a radially movable free end and a fixed connecting end, the free and fixed ends being located substantially at the same axial level, so that the flexible legs are deformable only in a plane perpendicular to the longitudinal axis X.
- the rod may comprise an insertion head and a neck, the insertion head being connected to the neck by an annular shoulder forming the retention profile, this annular shoulder extending radially outwards from the neck, the insertion head deforming the flexible legs of the sleeve radially outwards when the rod is inserted into the sleeve, the flexible legs (13) of the sleeve coming into radial contact with the neck and into axial contact with the annular shoulder.
- the flexible legs of the sleeve all come into pressed radial contact with the neck.
- the rod may comprise an insertion head, the flexible tabs are formed by the insertion head, the flexible tabs deforming radially inwards upon insertion of the rod into the sleeve, the flexible tabs of the rod forming at least in part the retention profile which comes into axial contact with a shoulder sector of the sleeve, which may be formed by flexible tabs or a conventional profile of the prior art.
- both the sleeve and the rod form flexible legs that come into axial contact
- the flexible legs of the sleeve have a curvature that is opposite to that of the flexible legs of the rod, or vice versa. This ensures that the flexible legs are never axially aligned.
- the legs cross, which ensures axial contact.
- the rod can form a truncated section below the neck, the flexible legs of the sleeve forming truncated lower surfaces, which engage with the truncated section of the rod.
- the flexible legs of the sleeve are in contact with both the annular shoulder, the neck and the truncated section of the rod. The rod is thus secured without axial play of the sleeve.
- the sleeve can form fluid product passages around the rod and between the flexible legs. This is the case of the actuating rod of a pump.
- the rod forms a corolla capable of coming into sealed contact with a contact edge to form a valve.
- the rod can internally form a fluid product channel. This is the case of the pusher of a pump or a valve.
- the invention also defines a fluid product dispenser comprising a retention system in which the fluid product passes through the retention system.
- the spirit of the invention lies in the fact that the retention system involves mainly, or even only, elastic deformation, purely radial preference, in order to reduce the axial thrust force of insertion, while guaranteeing perfect axial centering.

- Figures 7a and 7b are views respectively in vertical cross section and in horizontal section through a second variant of the retention system of Figures 2 to 5,
- Figure 8 is a partially cutaway perspective view of a fluid product dispenser incorporating a retention system of the invention.
- Figure 9 is a schematic vertical cross-sectional view of a push rod mounted on an actuating rod of a pump or valve.
- the retention system comprises a sleeve and a rod that is inserted and held in place in the sleeve, such that the two parts are then integral with each other and form an entity.
- the sleeve 1 b and the rod 2 b may be part of an actuating rod comparable to that of Figure 1 , which was used to illustrate the prior art.
- the sleeve 1 b is formed by the upper part and the rod 2 b forms the lower part of the actuating rod.
- the sleeve 1 b comprises a cylindrical portion 10 which defines a longitudinal axis X and forms an internal wall 11 , which is mainly cylindrical.
- the cylindricity of the wall 11 is broken by several vertical ribs 12, which can extend over all or part of the height of the cylindrical portion 10. These vertical ribs 12 project radially inwards. Between these vertical ribs 12, several passage sections for the fluid product are defined, which travels inside the sleeve 1 b. It can be noted that the passage sections are larger than the horizontal cross sections of the vertical ribs 12.
- the flexible legs 13 extend substantially in the extension of the ribs 12 towards the inside of the sleeve 1b, but in a non-radial manner. Indeed, the flexible legs 13 have a curvature which deviates them from the perfectly radial direction, in the manner of a comma.
- the fixed connection end 131 merges with the rib 12 and the free end 132 extends to the level of the center of the sleeve 1 b.
- the flexible legs 13 form a contact zone 133, oriented towards the center of the sleeve.
- This contact zone 133 defines a cylinder section centered on the X axis, so that all of the contact zones 133 of the different flexible legs 13 define a fictitious cylinder centered on the X axis.
- the flexible legs 13 define upper surfaces 134, which are preferably flat and perpendicular to the X axis and lower surfaces 135, which are preferably frustoconical.
- the upper surfaces 134 constitute shoulder sectors within the meaning of the invention, which are intended to come into axial contact with the annular shoulder 23 of the rod 2b.
- the stem 2b is preferably solid, except at its lower end, which forms a truncated corolla 26. Above this corolla 26, the stem 2b forms a main trunk 20, which is cylindrical in shape. Above the trunk 20, the stem 2b forms a truncated section 25, which reduces the diameter of the main trunk 20.
- a neck 24 connects to the truncated section 25: the neck 24 is preferably cylindrical, but with a diameter which is smaller than that of the main trunk 20. It can be said that the truncated section 25 makes the connection between the trunk 20 and the neck 24, both cylindrical.
- the rod 2b forms an insertion head 21, which connects the neck 24 by forming an annular shoulder 23, which extends in a plane perpendicular to the longitudinal axis X.
- the maximum diameter of the head 21 is greater than that of the neck 24.
- the insertion head 21 defines an external surface 22 of ogival or truncated shape to facilitate its insertion between the flexible tabs 13 of the sleeve 1 b.
- the corolla 26 may be intended to come into sealed contact with a contact edge formed by a piston or a fixed part.
- the rod 2b is seen being axially engaged in the sleeve 1b: only the head 21 of the rod 2b is inserted into the sleeve 1b. It is easy to understand that the head 21 of the rod 2b will come into contact with the flexible tabs 13. More precisely, the external surface 22 of the head 21 will come into contact with the lower surfaces 135 of the flexible tabs 13. The contact of the ogival or truncated shape of the external surface 22 against the truncated shape of the lower surfaces 135 induces a cam movement on the flexible tabs 13, which will be deformed radially outwards, as previously described, in the manner of the blades of a diaphragm.
- the free ends 132 of the flexible tabs 13 are moved towards the internal wall 11 of the sleeve 1b, with no or almost no axial component.
- the deformation of flexible legs 13 is progressive depending on the configuration of the external surface 22 until reaching a maximum deformation, corresponding to the maximum diameter of the head 21, at its annular shoulder 23.
- the flexible legs 13 will be able to relax elastically, as soon as the annular shoulder 23 of the head 21 has reached above the upper surfaces 134 of the flexible legs 13. This elastic relaxation can be described as snap-fastening.
- the flexible legs 13 are then housed around the neck 24: the curved contact zones 133 advantageously come into pressed contact against the external wall of the neck 24.
- the flat upper surfaces 134 of the flexible legs 13 advantageously come into contact with the annular shoulder 23 of the rod 2b and the frustoconical lower surfaces 135 advantageously come into contact with the frustoconical section 25 of the rod 2b.
- the flexible legs 13 completely fill the space formed by the neck 24.
- the external surface 22 of the head 21 can however remain away from the vertical ribs 12.
- Figures 6a and 6b illustrate a first variant embodiment in which the sleeve 1b is identical or similar to that of the embodiment of Figures 2 to 5.
- the stem 2c of Figures 6a and 6b differs from that of Figures 2 to 5 in that the neck 24c is longer than the neck 24, which implies that the annular shoulder 23 is further from the frustoconical sector 25 than in the first embodiment of Figures 2 to 5. Since the flexible legs 13 of the sleeve 1b are identical to those of Figures 2 to 5, it follows that the upper surfaces 134 and the lower surfaces 135 cannot both come into contact with the annular shoulder 23 and the frustoconical sector 25 at the same time. A pressed contact of the flexible legs 13 against the neck 24c is preferred.
- Figures 7a and 7b illustrate a second variant embodiment in which the sleeve 1b is identical or similar to that of the embodiment of Figures 2 to 5.
- the rod 2d of Figures 7a and 7b differs from that of Figures 2 to 5 in that the insertion head 21d of the rod 2d forms flexible tabs 213, which are deformable in the same manner as the flexible tabs 13 of the sleeve 1b, i.e. radially in the manner of a diaphragm.
- the flexible tabs 13 are deformable radially outward to open the passage of the head 21 or 21d, while the flexible tabs 213 are deformable radially inward to reduce the useful diameter of the head 21d.
- the flexible legs 213 are here in the form of twisted or helical strips, which extend over a major part of the height of the head 21 d.
- the legs 213 together form an annular shoulder 214, which comes in contact, preferably pressed, against the upper surfaces 134 of the legs 13 of the sleeve 1 b.
- the legs 13 preferably come into pressed contact against the neck 24 and the lower surfaces 135 come into contact with the truncated sector 25.
- the legs 13 of the sleeve 1 b have a curvature which is opposite to that of the legs 213 of the head 21 d, in order to guarantee constant axial contact between the legs 13 and 213.
- the sleeve 1b and the rod 2b, 2c and 2d can be made of any suitable plastic material, and preferably of PE or PP, whose recycling process is efficient.
- the retention systems of the invention which have just been described with reference to FIGS. 2 to 7b can be implemented in various applications, in various devices, and in particular in a fluid product dispenser equipped with a pump or a valve. In the latter case, fluid product is intended to pass through the retention system, either between the flexible tabs 13 and/or 213, or inside the rod.
- FIG 8 we see an embodiment of the invention which is similar to that of Figures 1 to 5, namely a controllable valve.
- the corolla 26a serves as a sealed support zone for the piston 3a, which is axially movable around the rod 2a and inside the sleeve 1a.
- the sleeve 1e and the rod 2e are axially movable against a return spring 4.
- the corolla 26 of the rod 2e is in constrained support against a sealing edge 32, which is fixed.
- the attachment of the rod 2e inside the sleeve 1e can be strictly identical or similar to that of the first embodiment of figures 2 to 5, that is to say with flexible legs 13 engaged under an insertion head 21 forming an annular shoulder 23 and a narrowed neck 24.
- the movement of the integral assembly formed by the sleeve 1e and the rod 2e makes it possible to detach the corolla 26 from the support edge 32, so as to open a passage for the fluid product, which will then flow inside the sleeve 1e around the rod 2e, and in particular around its insertion head 21.
- the retention system of the invention has been implemented to mount a pusher P on an actuating rod, and in particular on the free end of a sleeve 1f.
- the pusher P forms an outlet duct P1, which opens at a dispensing orifice P2.
- This outlet duct P1 is connected upstream to a channel 27 formed inside a rod 2f, which forms at its lower end an insertion head 21, similar or identical to that of the previous embodiments.
- the head 21 forms a flat annular shoulder 23 which is then extended by a narrowed neck 24 and a truncated cone section 25.
- the channel 27 passes through the entire rod 2f and opens at the lower end of the insertion head 21f.
- the sleeve 1f internally forms several flexible tabs 13, which may be identical or similar to the tabs 13 of the first embodiment. It may however be noted that there are no vertical ribs 12 in this embodiment: the flexible tabs 13 are directly connected to the inner wall of the sleeve 1f. The tabs 13 are elastically snapped into the housing formed by the neck 24, advantageously coming into contact with the annular shoulder 23 and the frustoconical section 25. To ensure the sealing of the rod 2f inside the sleeve 1f, a sealing ring 28 is also provided which projects radially outwards and comes into contact with the inner wall of the sleeve 1f.
- the actuating rod By axially pressing on the pusher P, the actuating rod is pushed inside the pump body, which has the effect of opening the outlet valve, which may be similar or comparable to that of FIG. 1, so that a dose of fluid product is forced into the sleeve 1 f, then through the channel 27 and finally through the outlet conduit P1 which opens at the level of the distribution orifice P2.
- the product passes through the retention system, and more particularly the rod 2f, which was not the case in the previous embodiments.
- the retention system of the invention comprises flexible tabs, which flex elastically radially outwards or inwards without axial component, during the passage of the insertion head of the rod to be housed by elastic relaxation and snap-fastening at the neck forming a local narrowing of the rod.
- Contact with the annular shoulder and the truncated cone section is advantageous, but not essential.
- the pressed contact of the flexible tabs radially against the external wall of the neck is advantageous, but not obligatory.
- the invention provides for implementing flexible legs that move radially without an axial component in the manner of the blades of a diaphragm at the level of the attachment of a rod inserted into a sleeve.
- the flexible legs can be produced at the level of the sleeve, as is the case in all the figures, or at the level of the rod, in particular at the level of the insertion head 21, as is the case in FIGS. 7a and 7b.
- the aim of the invention remains the same, namely that the insertion of the rod inside the sleeve only generates reversible elastic deformations. radial without axial component, and very little or no permanent deformations.
