- the dispenser comprises a spraying device.
- the device comprises a manual actuating head 6 secured, for example by snapping, to a pump introduced into the neck 3.
- the pump comprises a generally cylindrical pump body 7 having two open ends.
- the pump body 7 delimits a compression chamber in its lower part. Furthermore, the pump body 7 encloses a mechanism in which a piston element 8 which can slide in sealed manner in the pump body 7 cooperates with an inlet valve to fill the compression chamber with the product or to empty it.
- the piston element 8 comprises an axial channel 13 through which fluidic communication is established between the compression chamber and a spray orifice 14 provided on a nozzle 15 mounted on the actuating head 6.
- a tube has an upper end opening into the compression chamber and a lower end located near the bottom wall of the bottle 1.
- the upper end of the pump body 7 is closed by a stent 9 integral with the body 7 and having an axial bore 10 for guiding the piston member 8 during its sliding.
- lugs 11 are formed on the outer face of the expander 9 and are inserted in notches 12 formed on the inner face of the pump body 7 to allow the latching of the expander 9 in the pump body. 7.
- the pump body 7 is extended radially by an annular assembly flange 16 made on the upper part of the body 7.
- the assembly flange 16 is made in one piece with the free end upper body 7.
- the annular assembly flange 16 may be axially offset relative to the upper free end or may be constituted by an annular insert attached rigidly to the pump body 7. In the latter case, one can choose for the collating flange 16 a different material from that of the pump body 7 and adapted to the functions described below of the collar 16.
- the pump is introduced into the neck 3 until the lower face of the flange 16 comes into deforming tight contact on a bearing zone formed on the upper part of the neck 3.
- the bearing zone may comprise a transverse support surface formed on the upper edge 18.
- the transverse support surface may constitute all or part of the upper transverse edge 18.
- the radial dimension of the assembly collar 16 is provided so that its free end is close to the angular edge 29.
- the distributor further comprises an assembly sleeve 19 set on the neck 3 and on the upper face of the assembly flange 16.
- the expander 9 also comprises a radial projection 20 whose lower face rests on the upper face of an inner portion of the assembly flange 16.
- the sleeve 19 is then deformed so as to make a bearing on the face upper radial projection 20 and a bearing on the upper face of the middle and outer portions of the assembly flange 16.
- the sleeve 19 is then folded along the outer side edge 23 of the radial edge 5 and then shaped to perform a snap on the shoulder 24.
- the assembly flange 16 extends radially inwards so as to project on the opening 2 of the neck 3.
- the outside diameter of the pump body 7 may be smaller than the inside diameter of the neck 3 so that the outer lateral face of the pump body 7 is arranged at a distance from the inside face of the neck 3.
- a pump is thus produced said "standard” which can be adapted in a sealed manner to necks of different dimensions and shape without imposing stress on the pump body 7 itself.
- the dimensions of the pump body 7 are adjusted to those of the neck 3.
- the assembly flange 16 has a deformable portion of reduced thickness 21.
- the deformable portion of reduced thickness 21 is median.
- the portion of reduced thickness 21 can thus form hinge so that the outer portion of the flange between the deformable portion of reduced thickness 21 and the free end forms a flexible flange 22.
- the thickness of the flexible wing 22 may decrease near the free end to give a generally rounded shape to the upper face of the flexible wing 22.
- This embodiment simplifies the deformation of the sleeve 19 forming a transition curvature between the middle and outer portions of the flange 16 on the one hand and the outer lateral edge 23 of the radial edge 5 on the other hand.
- the contact of the assembly flange 16 on the transverse support surface of the neck 3 is then distributed over a larger surface and in a uniform manner, which improves the assembly and the sealing of the bottle 1.
- the deformable portion of reduced thickness 21 comprises a groove 25 formed on the lower face of the assembly flange 16.
- the groove 25 is flared to have two inclined walls diverging towards the lower transverse face and ensure, by cooperation with a rod 26 projecting carried by the bearing zone formed on the neck 3, a positioning and a 7.
- the ring 26 may be carried by the transverse support surface.
- the groove 25 placed on the rod 26 by tightening by means of the sleeve 19 also ensures a complementary seal.
- the inclined walls allow the sliding of the outer face of the rod, of frustoconical shape, for example, to facilitate positioning and wedging.
- the ability of the flexible wing 22 to deform allows to overcome the precise relative positioning of the groove 25 relative to the rod 26 and achieve improved positioning and timing while creating a complementary seal. This flexibility also offers better adaptability of the pump to different necks or with dimensional variations.
- the flange 16 thus produced makes it possible to dissociate at least partially the functions of sealing, wedging and positioning of the flange.
- the seal is mainly achieved by the inner and outer portions due to the support of the projection 20 of the expander 9 and the assembly sleeve 19.
- the setting and positioning they are mainly made by the median portion of reduced thickness 21.
- the deformable portion of reduced thickness 21 also comprises a cavity 27 formed on the upper face of the assembly collar 16.
- the bearing zone also comprises a lateral wedging surface provided on all or part of the outer lateral edge 23 and an angular hooking surface formed on all or part of the angular edge 29.
- the flexible wing then has a flange 28 which extends axially downwards. The cuff 28 comes into tight contact with the lateral wedging surface by capping the angular hooking surface.
- the wedging can be achieved by the median portion of the flange 16 with the cooperation of a ring 26 and the groove 25 and / or by the outer portion of the flange 16 with the lapel 28.
- the positioning of the body the flexibility of the flange 22. This flexibility also promotes the attachment of the pump body 7 on collars with dimensional variations.
- the seal it is made radially mainly by the inner and outer portions of the flange 16 and axially by the flange 28.
- the flexible wing 22 is inclined downwardly relative to the inner portion of the collar 16.
- This embodiment shown in Figure 2 allows the flange 16 to better marry the support zone of the upper part of the neck 3 and thus improve the setting and attachment of the pump body 7.
