Description

Dispensing device for fluid product and container for fluid product

The present disclosure relates to the field of dispensing devices for fluid product and containers for fluid product comprising such dispensing devices.

The present disclosure relates more particularly to the field of dispensing devices for cosmetic fluid product and containers for cosmetic fluid product comprising such dispensing devices.

Generally, the distribution systems for fluid product are formed by a set of four parts, assembled and fixed on the pump of a container in order to allow the distribution of the fluid product.

This four-piece set includes a push button on which a user presses to diffuse the fluid product, a diffuser, through which the fluid product comes out, a cover which generally has an aesthetic function, and a hoop allowing the assembly of the four pieces on the container pump. The hoop generally has one or more springs, allowing the pump to be actuated following pressure on the push button by the user.

Although the set of four parts is efficient in terms of the delivery of the fluid product, the manufacture of four separate parts entails an exponential risk of manufacturing defect, moreover, once assembled the use of four separate parts entails an increased risk of seizing during regular use, especially daily.

There is therefore a need to improve such distribution devices.

It is known in particular from document US20080029551 a dispensing device formed of a push button, a diffuser and a hoop intended to hide the assembly from the outside. The push button features two leaf springs molded directly onto the push button. However, product distribution is not optimal due to the type of spring used.

Reference is now made to the , illustrating a device 10 for dispensing fluid and a container 20 for fluid. The fluid product can be a liquid product or a non-solid product. The fluid product is advantageously a cosmetic product of the perfume, cream, serum type, or any other cosmetic product that can be delivered by a pump.

The dispensing device 10, or device 10, is intended to be fixed on a container 20, and in particular on a pump 21 of the container 20. The container 20 comprises the fluid product.

The dispensing device 10 comprises a push button 11, a diffuser 12, a fixing sleeve 13, a base 14, connected to the fixing sleeve 13 and a deformable structure 15.

These elements are visible more particularly on the .

In particular, the push button 11 is mounted at least in part on the diffuser 12. The diffuser 12 is mounted on an outlet rod 22 of the pump 21 of the container 20. Pressing the push button 1 causes a press on the diffuser 12 allowing the diffusion of the fluid product.

The fixing sleeve 13 allows the docking of the device 10 on the container 20. Thus, for this purpose, the fixing sleeve 13 is mounted on an outer wall of the pump 21 of the container 20.

The fixing sleeve 13 can be mounted on the outer wall of the pump 21 by clamping, snap-fastening, gluing or by any means making it possible to fix the fixing sleeve 13 on the pump 20.

The fixing sleeve 13 has an upper end 13a and a lower end 13b.

The fixing sleeve 13 is connected to a base 14. More particularly, the base 14 extends radially outward from the lower end 13b of the fixing sleeve.

When the fixing sleeve 13 is mounted on the container 20, the lower end 13b of the fixing sleeve 13 as well as the base 14 are coplanar with a neck 23 of the container 20.

In a variant, when the fixing sleeve 13 is mounted on the container 20, the lower end 13b of the fixing sleeve 13 as well as the base 14 are in contact with the neck 23 of the container 20.

When the fixing sleeve 13 is mounted on the container 20, the upper end 13a of the fixing sleeve 13 can face the diffuser 12. More particularly, the fixing sleeve 13 can have an inner enclosure of complementary shape and size. to that of the diffuser 12, allowing the diffuser 12 to be inserted into the enclosure formed by the fixing sleeve 13, in particular at its upper end 13a, when the diffuser is mounted on the outlet rod 22 of the pump 21 of container 20.

In this embodiment, when pressure is exerted by pressing the push button 11, mounted on the diffuser 12, itself inserted into the inner enclosure of the fixing sleeve 13, the diffuser 12 is itself subjected to the same pressure. The diffuser 12 then performs a downward movement while being guided by the inner enclosure of the fixing sleeve 13. After cessation of pressing the push button 11, the diffuser 12 returns to its initial position, still guided by the inner enclosure of the fixing sleeve 13.

In the non-limiting embodiment of the , the fixing sleeve 13 may have, at its upper end 13a, a groove 13c in which the nozzle 12a of the diffuser 12 may be inserted, in order to promote its guidance.

The inner enclosure of the fixing sleeve 13, at its lower end 13b, may also have a shape complementary to the pump 21 of the container 20, thus facilitating the assembly of the fixing sleeve 13 on the pump 21.

Moreover, as seen for example on the , the push button 11 can have a shape such that it can be inserted at least partially into the fixing sleeve 13. This can make it possible to further promote the guiding of the push button 11 when it is subjected to downward pressure. .

The dispensing device 10 further comprises a deformable structure 15. In one embodiment, the deformable structure 15 extends from the base 14 upwards. The deformable structure 15 extends upwards so as to surround at least partially, and preferably completely, the fixing sleeve 13.

The deformable structure 15 also has an opening 15a to provide a passage for a nozzle 12a of the diffuser 12.

Thus, when the diffuser 12 is mounted on the outlet rod 22 of the pump 21 of the container 20, the nozzle 12a of the diffuser is accessible from outside the deformable structure, thus allowing the diffusion of the fluid product.

In an embodiment presented on the , the opening 15a of the deformable structure 15 has the shape of a slot, open at its upper end. Thus, the assembly of the diffuser is done by inserting the nozzle of the diffuser 12 into the opening 15a in the form of a slot.

In one embodiment, the push button 11, intended to bear against the diffuser 12 when it is mounted on the deformable structure 15, may have a tab 11a. The tab 11a has a shape complementary to that of the slot-shaped opening 15a. The tongue 11a may also have a shorter length than that of the slot-shaped opening 15a, so that when the push button 11a is mounted on the deformable structure 15a, the tongue closes the upper end of the opening. 15a in the form of a slit.

In another embodiment, the opening 15a of the deformable structure 15 has any other shape allowing the nozzle 12a of the diffuser 12 to be inserted inside.

In particular, as seen on the , the opening 15a is closed at its upper end. Thus, the nozzle 12a of the diffuser 12 can be inserted by force into the opening 15a.

In one embodiment, the fixing sleeve 13, the base 14 and the deformable structure 15 form a single part 16.

In one embodiment, part 16 is manufactured by 3D printing.

In another embodiment, the part 16 is formed by molding or any other manufacturing process making it possible to obtain the same part 16.

In one embodiment, part 16 is made of a polyamide, elastomer or polypropylene material.

FIGS. 3a and 3b illustrate a schematic sectional view of the dispensing device 10 mounted on the container 20 respectively in a rest position and in an actuation position during which a downward pressure is operated on the push button, causing the diffusion of the fluid product. .

In the rest position, the total height H of the device 10 is defined by the height of the push button 11 assembled on the deformable structure 15

When a downward pressure is exerted on the push button 11, a downward movement of the diffuser 12 and of the pump 21 of the container 20 is caused.

To allow this displacement, the deformable structure 15 deforms elastically towards an actuation position illustrated .

The deformable structure 15 therefore makes it possible to play the role of leaf springs known from the prior art.

The elasticity of the deformable structure 15 can be obtained according to different embodiments.

According to one embodiment, the deformable structure 15 is capable of deforming elastically vertically downwards in a homogeneous manner under the effect of pressure exerted downwards on the push button 12.

In this embodiment, the deformable structure 15 may have a mesh structure formed by structural elements 15b.

In particular, the structural elements 15b can be intersected, in order to form the mesh.

The structural elements 15b can in particular intersect at an angle of 90°.

The structural elements 15b can be spaced at a regular distance from each other. The distance is for example between 0.5 and 1.5 mm.

Thus, when the push button 11 is actuated, the structural elements 15b collect on themselves, causing the elastic deformation of the deformable structure 15.

In the embodiment illustrated in Figures 2, the structural elements 15b are arranged in a helical distribution. Thus, the structural elements 15b can be distributed according to a helix pitch comprised between once the height of the deformable structure 15 and twice its height. This example is non-limiting and a larger propeller pitch could be defined.

Structural elements 15b can be distributed in a helical arrangement to the left and other structural elements 15b can be distributed in a helical arrangement to the right.

According to this arrangement, the structural elements 15b arranged to the right can intersect the structural elements 15b arranged to the left at an obtuse angle comprised between 110° and 170° or at an acute angle comprised between 10° and 70°, in order to ensure good elasticity of the deformable structure.

According to another embodiment, the deformable structure 15 may have recesses rather than a mesh. Thus, the deformable structure 15 may comprise recesses spaced apart from each other. Thus, the deformable structure 15 may comprise recesses spaced apart from each other. This spacing can be made in a regular or pseudo-regular pattern.

The recesses may be spaced the same distance from each other.

The recesses can have any geometric shape. Thus, the recesses can be circles, diamonds, squares, triangles, etc.

According to another embodiment, the deformable structure 15 may have horizontal grooves, making it possible to deform the elastically deformable structure vertically and downwards.

According to another embodiment, the deformable structure 15 is capable of deforming elastically downwards according to a twisting movement under the effect of pressing the push button downwards.

Thus, a mesh ensuring this torsion is provided on the deformable structure 15.

Similarly, the patterns of the recesses described above can fulfill this function.

According to another embodiment, the deformable structure 15 is capable of deforming elastically downwards and radially under the effect of pressing the push button downwards.

In this embodiment, the deformable structure 15 can then have a domed shape, for example towards the outside, deforming according to the orientation of the curvature of the domed shape, under the effect of pressing the push button 11.

Similarly, the deformable structure 15 may have an inwardly domed shape, folding as described above, but in the opposite orientation.

In another embodiment, the deformable structure may have a structure according to the Voronoi diagram.

In one embodiment, the deformable structure 15 has a generally cylindrical shape.

In this embodiment, the base 14 can be an annular base, the push button 11 having a cylindrical shape so as to match the shape of the deformable structure 15.

In another embodiment, the deformable structure 15 has any other shape, in particular square or pseudo-cylindrical, diamond-shaped or triangular.

According to this embodiment, the base 14 and the push button 11 have the same shape as that of the deformable structure, giving the dispensing device 10 a pleasant and coherent external appearance.
