Definitions

  • Fixing member and fluid dispenser comprising such a fixing member
  • the present invention relates to a fixing member and a fluid dispenser comprising a container, a dispensing member such as a pump or a valve and a fixing member for fixing the dispensing member to the container.
  • a dispensing member such as a pump or a valve
  • a fixing member for fixing the dispensing member to the container.
  • Such dispensers are frequently used in the field of perfumery, cosmetics or even pharmacy to dispense fluid products by manual support using a finger on a pusher.
  • the present invention applies inter alia to a type of container forming an opening or a neck defining an internal wall which forms a narrowed opening section below which the wall is hollowed out at least locally outwards to form a lower opening section hollowed out.
  • the internal wall of the neck can also be cylindrical.
  • the fixing member this comprises receiving means for receiving the body of the dispensing member and a fixing skirt intended to be force fitted into said opening.
  • the skirt comprises an external wall defining a section intended to come into contact with the internal wall of the neck, when the skirt is fitted fully into the neck of the container.
  • a dispenser comprising a fastening member of this type is known from document US 3,937,366.
  • the internal wall of the container neck comprises a peripheral groove in which a rib formed on the external wall of the skirt is snapped on. .
  • the part of the skirt located just above the rib has a diameter less than that of the bottom of the rib, even when the skirt is not yet fitted into the neck of the container.
  • the external profile of the skirt is perfectly complementary to the internal profile of the container neck.
  • the shape of the groove in the inner wall of the neck is exactly complementary to the shape of the rib of the skirt.
  • This member uses a ring on which is mounted a pump or a valve.
  • This ring also cooperates with the internal wall of a container neck which has a narrowed opening section below which extends a hollowed out opening section.
  • the ring is formed with a skirt intended to come to engage inside the neck.
  • This skirt has an external radial projection intended to be housed in the recessed opening section which is here in the form of a simple peripheral recess formed inside the internal wall of the neck.
  • This is a snap system which consists in engaging the external projection of the skirt in the internal recess of the neck. The skirt is deformed only momentarily, until the projection reaches the recess.
  • the skirt relaxes to resume its initial shape.
  • the skirt defines a section of smaller diameter which is received at the level of the narrowed opening section formed just above the internal recess of the neck.
  • the outer diameter of the section of the skirt located at the narrowed opening section of the neck has a diameter less than the latter. This is also not described in the text of this document.
  • the fixing member comprises latching means capable of being housed in said recess of the internal wall of the neck; in this case, these latching means are formed by the external projection.
  • the plastic fixing members are subject to a creep of the plastic at the level where they are in contact pressed against the neck. This results in the medium term in a loosening of the grip of the organ in the cervix, so that the fixing member can be easily torn from the cervix.
  • the present invention seeks to remedy the drawbacks of the prior art by defining a fixing ring which achieves both a solid fixing and a perfect seal, and this even in the long term.
  • the present invention provides a fixing member for fixing a dispensing member on a container neck, said fixing member comprising receiving means intended to receive said distribution member and fixing means intended to cooperate with an internal wall and an abutment surface of the container neck, when the fixing member has reached its final fixing position on the neck, said fixing means comprising a flange which extends outwards and which is intended to abutting on the abutment surface of the neck in the final position and a skirt intended to be engaged in the neck so as to come into tight contact with the internal wall of the neck in the final position, said skirt comprising an upper end and a lower end , characterized in that the skirt comprises an elastically deformable section radially inwards which is adapted to be and remain el astically deformed by contact with the internal wall of the neck in the final position.
  • This contact is a tight and advantageously tight tight contact and is also permanent since the deformable section remains deformed in the final position of the ring in the neck.
  • the upper end of the skirt is substantially non-deformable.
  • the lower end of the skirt can be substantially non-deformable.
  • the deformable section is located between the non-deformable upper and lower ends. This elastically deformable section can then take the form of a flexible crown held firmly at its two solid ends.
  • the lower end forms a contact surface adapted to bear against the dispensing member.
  • the deformable section internally defines an annular housing at which the deformable section is intended to remain out of contact with the dispensing member so that it can be deformed inward without coming into contact of the distribution body.
  • the housing is located above the lower end of the skirt which defines a contact surface, advantageously sealed, which is adapted to bear against the dispensing member.
  • the housing contains a flexible elastic material adapted to be compressed radially inwards by the deformable section, advantageously against the dispensing member.
  • the flexible material is added or molded into the housing. It is preferably in contact with the skirt and the body of the dispensing member without occupying the entire volume of the housing.
  • the deformable section is externally cylindrical.
  • the deformable section is provided with at least one profile projecting towards the outside which can advantageously be adapted to be housed in a recess formed in the internal wall of the container neck.
  • the invention also defines a fluid dispenser comprising a container forming a neck, a dispensing member and a fixing member.
  • the neck defines an internal wall formed with a recess intended to receive the deformable section of the skirt.
  • the skirt is spaced from the body by an intermediate space.
  • FIG. 1 is a schematic cross-sectional view through a dispensing member equipped with a fixing member according to the invention ready to be inserted into a container neck
  • - Figure 2 is a view corresponding to that of the FIG. 1 with the fixing member engaged in the container neck
  • FIG. 3 is a view similar to that of FIG. 1 for a second embodiment
  • FIG. 4 is a view similar to that of FIG. 2 for the second embodiment
  • FIG. 5 is a view similar to that of FIG. 1 for a third embodiment of the invention.
  • FIG. 6 is a view similar to that of Figure 2 for the third embodiment according to the invention.
  • the dispenser of the invention comprises three constituent elements, namely a container 3, a dispensing member 2 and a fixing member 1.
  • the container 3 is here provided with a neck 30 which projects upwards from of the body of the container (not shown) whose function is to contain fluid.
  • the neck defines an opening which allows communication inside the container.
  • the container in which there is no protruding neck, but simply an opening in the body of the container.
  • the tem-inal part of the neck 30 is located directly at the shoulder 37. We can then speak of opening without neck.
  • the protruding neck is therefore not an essential element in the present invention.
  • the neck 30 comprises an internal wall 31 which is not cylindrical, but on the contrary has a narrowed opening section 32 below which a hollowed out opening section 23 is defined.
  • the section narrowed opening is located near the outlet of the neck which forms at this point an upper end 35 of annular shape.
  • the narrowed opening section 32 is connected to the upper end 35 by a tapered or flared attack section 34.
  • the narrowed opening section 32 can be substantially cylindrical.
  • the recessed opening section 14 can also be of substantially cylindrical section.
  • the hollowed out opening section 33 is in the form of a peripheral recess which extends over a certain height of the neck, which is extended downwards by another section of diameter substantially equal to that of the narrowed opening section.
  • the hollowed out opening section is in the form of a plurality of recesses distributed over the internal periphery of the neck. In other words, whatever the shape of the hollowed out opening section, it must at least locally have an internal diameter greater than that of the narrowed opening section.
  • the narrowed opening section is cylindrical, and the hollowed out opening section 14 extends downward from the narrowed opening section 13 starting with a flared transition section.
  • the flared transition section is part of the hollowed out opening section 33 since its diameter is less than that of the narrowed opening section 32.
  • the hollowed out opening section 33 then extends downward to connect to the shoulder 37.
  • the neck has a cylindrical internal wall, at least over the part of its height intended to cooperate with the fixing member.
  • the dispensing member 2 which is here a pump or a valve, comprises a body 20 defining at its upper end a flange 21 which projects outwards. Below this flange, the pump body defines a body part 22 below which a second body part 24 of smaller diameter is connected so that between the two body parts 22 and 24 there is a transition 23 in the form of a frustoconical step, as can be seen more clearly in the figures. Below the second body part 24, the body 20 defines another body part which also has a smaller diameter.
  • the body 20 is four stages, since it comprises four parts of the body decreasing in diameter starting from the flange 21.
  • the pump 2 comprises an actuating rod 25 which slides inside the body 20.
  • This actuating rod 25 is surmounted by a pusher 26 defining a dispensing orifice.
  • a pusher 26 defining a dispensing orifice.
  • the purpose of the fixing member 1 is to secure the dispensing member 2 and fix it in the opening of the neck 30.
  • the member is in the form of a fixing ring comprising receiving means under the form of a sleeve 12 internally defining an encasing housing 120 in which the flange 21 of the pump is received.
  • the fixing ring 1 also includes a fixing skirt 10 intended to be inserted inside the neck. This skirt 10 extends substantially in the extension of the sleeve 12. It may be noted that the skirt 10 is not in contact with the body at the second body part 22, but that there remains a housing or an intermediate space 106 which prevents any contact or interference of the skirt 10 on the body 20.
  • the skirt has an outer wall which is substantially cylindrical as in the embodiment of Figures 3 and 4, or profiled in that of Figures 1, 2, 5 and 6. At its lower end, the skirt can be formed with a chamfer 108 which makes it easier to insert the skirt into the opening of the collar.
  • the skirt 10 therefore extends substantially in the extension of the sleeve 12 away from the body 20 at its upper section 22 to form a housing or an intermediate space 106.
  • the flange 21 of the body 20 is snapped inside the sleeve 12 which gives it a certain rigidity or non-deformability.
  • a flange 11 which projects radially outward.
  • This flange 11 is provided at its lower face with a groove 110 intended to receive a sealing ring 36 formed at the upper end 35 of the neck 30.
  • the radial flange 11 also provides a characteristic of non-deformability of the ring so that the upper end 101 of the skirt is substantially non-deformable.
  • the skirt 10 defines a lower end 102 which is also substantially non-deformable.
  • This characteristic of indeformability is provided here by the fact that the lower end 102 defines a contact surface 105 adapted to come into bearing contact against the body 20, for example at the level of the frustoconical transition section 23 and the section 24.
  • the body 20 is already held in a perfectly stable manner inside the fixing member due to the engagement of the flange 21 in the engagement housing 120 formed by the sleeve 12
  • the contact surface 105 still contributes to the stability of the body 20 in the fixing member, firstly because it encloses the section 24, and secondly because it forms a stop against the frustoconical transition section. 23.
  • the upper 101 and lower 102 ends of the skirt 10 are substantially non-deformable.
  • the skirt 10 further defines an elastically deformable section 103 which here extends between the non-deformable ends 101 and 102.
  • This elastically deformable section 103 is here in the form of a substantially cylindrical section whose two ends 101 and 102 are substantially non-deformable. It should be noted that this characteristic of elastic deformability is given by the fact that the ends are substantially undeformable so that the elastically deformable section is somehow maintained or "stretched" between these ends.
  • the elastically deformable section 103 is located at the level where the housing or intermediate space 106 is formed which separates the skirt 10 from the pump body 20 at the level of the upper section 22.
  • this housing 106 is formed by the internal wall of the skirt 10, non-deformable lower end 102 of the skirt 10, the upper section 22 of the body 20 and the flange 21 snapped into the sleeve 12.
  • This housing 106 which is largely delimited by the skirt 10 allows the elastically deformable section 103 to be deformed radially inward without coming into contact with the body 20. It can thus be said that the housing 106 serves as clearance space to allow the deformation of the section elastically deformable 103 inwards.
  • this housing 106 contains an elastic flexible material 4, which is preferably very little subject to material creep.
  • this material 4 must have a characteristic of permanent elasticity even after a long period of time.
  • the piece of flexible material 4 partially rempht the housing 106 so as to leave a free or empty part 107.
  • the material 4 can come to expand in the empty part 107 when the elastically deformable section 103 is constrained radially inwards , and thereby decreases the volume of the housing 106.
  • the material 4 is preferably arranged so as to be in contact with both the internal wall of the skirt and the external wall of the upper section 22 of the pump body 20.
  • the elastically deformable section 103 can play the function of spring or elastic return making it possible to confer on the elastically deformable section 103 its characteristic of elastically deformability, in the event that it comes to lose it by creep of material.
  • the plastic material constituting the skirt 10 is flowable, it is preferable to partially fill the housing 106 with such a flexible elastic material 4. This material makes it possible to permanently push the skirt 10 against the internal wall of the neck by reaction on the pump body 20.
  • the piece of flexible elastic material 4 consequently supplements the elastically deformable section 103 in case this is necessary.
  • the neck 30 is formed with a narrowed opening section 32 which is extended downwards by a hollowed section 33.
  • the skirt 10 is formed at its outer wall with a projecting annular bead 104 which is located in the lower part of the elastically deformable section 103.
  • the narrowed opening section 32 Since the internal diameter of the narrowed opening section 32 is less than the external diameter of the elastically deformable section 103, before the fixing member is fitted into the neck, the narrowed opening section 32 has the effect of deforming the elastically deformed section able 103 inwards so as to form a boss 134 which reduces the internal volume of the housing 106 in which the piece of flexible material can be placed 4.
  • the elastically deformable section 103 is thus deformed around the narrowed opening section 32 so that the upper part of the elastically deformable section extends slightly over the frustoconical section 34 of the neck and the lower part of the elastically deformable section provided with the cord 104 is housed in the hollowed section 33, which contributes to or improves the fixing and blocking of the fixing member inside the neck.
  • the cord 104 is snapped into the hollowed out section 103 while the elastically deformable section is pressed against the opening section.
  • this pressure action can advantageously be supplemented by the presence of the piece of elastic material 4 in the housing 106.
  • the elastically deformable section 103 has an outer wall substantially or perfectly cylindrical.
  • the neck is similar or identical to that of the embodiment of Figures 1 and 2, that is to say with a narrowed opening section 32 which is extended downwards by a hollowed section 33.
  • the skirt 10 is deformed in the same manner as in Figure 2.
  • the skirt 10 of Figures 3 and 4 does not have protruding cord 104 formed at the lower part of the elastically deformable section 103.
  • the result is practically identical except that the lower part of the elastically deformable section 103 does not penetrate as much into the hollowed section 33 of the neck. This demonstrates that the skirt 10 can be cylindrical or formed with more or less projecting profiles.
  • the third embodiment of Figures 5 and 6 is substantially identical with respect to the fixing member to that of Figures 1 and 2, in that the skirt 10 is formed with a protruding bead 104 formed at the elastically deformable section 103.
  • the internal wall 31 of the neck 30 is here perfectly cylindrical. Once engaged in the neck, the skirt 10 is deformed at the level of its elastically deformable section 103 towards the inside so as to form a boss 134 which penetrates into the housing 106 and thus deforms the piece of flexible material 4.
  • the external wall of the skirt 10 it has a configuration identical to that of the cylindrical internal wall 31 of the neck 30.
  • the skirt engaged in the neck is elastically deformable (and not deformed by displacement of material or creep): this characteristic of elastic deformability allowing the skirt to exert constant pressure over time against the internal wall of the neck.
  • the skirt can be helped in this by a piece of durable elastic flexible material placed inside the skirt.
