Definitions

• Fixing ring and fluid dispenser device comprising such a ring
• the present invention relates to a ring for fixing a dispensing member, such as a pump or a valve, to a neck of a container containing product to be dispensed, as well as a device for dispensing a fluid product comprising such a Ring.
• a dispensing member such as a pump or a valve
• the fixing of a dispensing member to a container neck is known in the state of the art and can in particular be done by crimping, screwing or snap-fastening.
• a fixing ring holding the body of a dispensing member is fixed to the neck of the container with the interposition of a seal, called a neck seal, in order to guarantee the tightness of the fixed ring. on said pass.
• the object of the present invention is to provide a fixing ring which does not reproduce the abovementioned drawbacks.
• the present invention therefore proposes to provide a fixing ring for a dispensing member on a container containing product to be dispensed, not requiring a seal.
• Another object of the present invention is to provide a dispensing device comprising such a fixing ring which is simpler, less expensive and easier to assemble.
• Another object of the present invention is further to provide a dispensing device in which the fixing ring is securely snapped onto the neck of a container without the possibility of tearing off said ring.
• Yet another object of the invention is to provide a ring for fixing a dispensing member to a container containing the product to be dispensed, making it possible to compensate and / or to absorb any tolerances or dimensional and / or geometric variations. of the container neck.
• the present invention therefore relates to a fixing ring for a dispensing member, such as a pump or a valve, on a neck of a container containing product to be dispensed, said fixing ring comprising deformable sealing means cooperating with said neck of said container to ensure a tight fixing of said dispensing member on said container.
• said sealing means comprise at least one elastically deformable lip.
• said sealing means comprise two deformable lips.
• said sealing means are produced in a single piece with said fixing ring.
• said sealing means are molded onto said fixing ring.
• the ring comprises latching means comprising a contact surface adapted to cooperate with a shoulder surface of said neck of the container to fix the dispensing member on said container, said contact and shoulder surfaces being substantially radial.
• the ring is produced in a single piece with a spindle fixed to the dispensing member and / or a ferrule defining the rest position of the dispensing member.
• the present invention also relates to a fluid dispenser device comprising a container and a dispenser member, such as a pump or a valve, further comprising a fixing ring as described above.
• said sealing means of the ring ensure a tight fixing of the dispensing member on the container.
• said neck of the container comprises an axially projecting part capable of cooperating with said deformable sealing means of the fixing ring.
• said deformable sealing means of the fixing ring cooperate with said neck of the container to define a sealed contact area providing the seal, said sealed contact area being at least partially oblique.
• said fixing ring makes it possible to compensate for dimensional and / or geometric variations in the neck of the container, linked to manufacturing tolerances.
• FIG. 1 represents a schematic view in longitudinal section of a dispensing device incorporating a fixing ring according to a first embodiment of the invention
• FIG. 2 represents a detailed view of the fixing ring shown in Figure 1
• Figure 3 shows a detailed view of a fixing ring according to a second embodiment.
• a product dispenser as shown comprises a container 3, a dispensing member 2 extended by a dispensing head 4 and a fixing ring 1.
• the container 3 contains product to be dispensed.
• This container 3 has a neck 30 defining an upper edge. The structure and function of this neck 30 will be described later.
• the dispensing member 2 can be any and in particular a pump, as shown in Figure 1, or a valve.
• the pump 2 is fixedly held on the container 3 by the annular fixing ring 1 fixed on the neck 30 of the container.
• the pump 2 can be fixed in a spinner 20 itself fixed on the container 3 by the fixing ring 1.
• said spinner 20 is produced in a single piece with said ring 1.
• a ferrule 11 can extend into the body of the pump 2 to define the rest position thereof.
• this ferrule 11 is also produced in a single piece with said fixing ring 1.
• the dispensing head 4 has a dispensing orifice 41 through which the product can escape following a manual actuation exerted on a support zone 40.
• an internal shoulder 42 located at the dispensing head 4 is designed to come into abutment with an external projection 12 formed on the spinner 20, and therefore advantageously on the fixing ring 1.
• the pump 2 is in the actuating position which explains that the internal shoulder 42 is not in abutment against the external projection 12.
• the cooperation of the internal shoulder 42 with the projection external 12 actually avoids any possibility of tearing off the dispensing head 4, and this cooperation is not necessarily carried out in the pump's rest position, but in the event of an attempt to tear off the head.
• the cooperation of the head with the ring is also used to define the rest position of the pump.
• the fixing ring 1 is advantageously fixed by snap-fastening on the neck 30 of the container 3. This fixing is ensured by snap-fastening means 15 of the fixing ring 1 positioned under the widened upper edge (also called a booklet) defined by the neck 30 of said container 3.
• this snap-in provides for the cooperation of a contact surface 115 formed on said fixing ring 1 with a corresponding shoulder surface 130 formed on said neck 30.
• the contact surface 115 projects inward substantially radially and the shoulder surface 130 forms a corresponding external recess, also substantially radial. Consequently, this cooperation of the contact surface 115 and the shoulder surface 130 can therefore be implemented in a plane that is slightly inclined or even completely radial.
• This embodiment thus guarantees a permanent and irremovable fixing of the fixing ring 1 on the neck 30 of the container and generates an axial latching force which promotes the sealing of the assembly.
• the fixing ring 1 comprises deformable sealing means 10 cooperating with the upper edge of the neck 30.
• the sealing means 10 of the ring 1 may comprise one or two deformable lip (s), preferably made at a radial flange 13 of said ring 1 The fineness of this or these lip (s) thus ensures both perfect sealing of the container neck and perfect compensation for the dimensional and / or geometric tolerances of the container necks.
• two lips are advantageously placed on either side of a projecting part 31 formed on said neck 30.
• this projecting part 31 can form an annular bead which comes into engagement with said sealing means. 10.
• the presence of two sealing lips, in particular on either side of the protruding part improves sealing and compensation of tolerances.
• this implementation makes it possible to produce particularly thin and deformable lips, which, while guaranteeing tightness, adapt perfectly to the neck, in particular the projecting part.
• the sealing means 10 form one or more annular ring (s) capable of cooperating in leaktight manner with the neck 30.
• these means sealing 10 are advantageously profiled so as to be pressed against a chamfered portion 32 of said neck 30 thus forming a sealed contact area at least partially oblique with respect to the radial flange 13 of the ring 1.
• This plating makes it possible to establish contact tightening seal between the radial flange 13 of said ring 1 and said neck 30 of the container 3.
• These sealing means 10 can either be molded at the level of said ring 1, in which case these means 10 can be made of more flexible material, or form with said ring 1 a one-piece assembly.
• a housing 14 can be provided at the level of the radial flange 13.
• FIG. 3 very schematically shows a fixing ring 1 produced in a single piece with a part of the body of the pump 2, the invention also applying to this case in which the fixing ring is not necessarily a separate item.
• the container 3, the dispensing member 2 and the head 4 can of course be made in any way.
• Other modifications are also possible for a person skilled in the art without departing from the scope of the present invention as defined by the appended claims.
