Figure 4 is a perspective view of the dispensing device according to the invention in which the bottle and the protective piece are assembled to one another. The invention relates to a device for dispensing a liquid, especially a cosmetic liquid. The cosmetic liquid is for example a perfuming water or a care liquid.

As illustrated in Figures 1, 2 and 4, the dispensing device comprises a bottle 1 and a protective part 2. The bottle 1 is designed to receive and contain the cosmetic liquid. The protective part 2 is, it, designed to surround the bottle 1 in particular to protect it by covering at least in part. The protection part 2 and the bottle 1 are designed to be assembled and / or interlocked to one another removably by a user.

As illustrated in particular in FIG. 1, the bottle 1 comprises a reservoir part, called reservoir 10, intended to contain and store the cosmetic liquid. The bottle 1 further comprises a positioning part 16, a magnet 14 and a connecting ring 12.

The bottle 1 is here advantageously provided with a dispensing element 18. The bottle 1 is thus usable independently of the rest of the dispensing device. In particular, the user can use the vial 1 independently of the protective part 2. In addition, the dispensing device is designed so that the assembly of the vial 1 and the protective part 2 one with the other can be done without the need to disassemble all or part of the bottle 1.

Here, and as will be described more precisely later, the reservoir 10, the positioning part 16, the magnet 14, the connecting ring 12 and the distribution element 18 are assembled together and secured. one another.

The bottle 1 comprises a lower end 104 and an upper end 109 and extends longitudinally in a main direction of longitudinal extension Xide the lower end 104 at the upper end 109. In particular, the bottle 1 extends longitudinally d a bottom of the tank 10 at an apex of the distribution element 18.

The tank 10 comprises a lower end 104, corresponding to the bottom of the tank 10, and an upper end 106. The tank 10 extends from the lower end 104 to the upper end 106 according to a main axial direction.

The main axial direction of the reservoir 10 is here confused with the main direction of longitudinal extension of the vial 1. In addition, the lower end 104 of the reservoir 10 is here merged with the lower end 104 of the vial 1.

The reservoir 10 has an inner surface 102 designed to be in contact with the cosmetic liquid and an outer surface 101 which faces the outside of the reservoir 10.

The reservoir 10 is here provided with a neck 108, or neck, in the vicinity of its upper end 106. In other words, the reservoir 10 terminates in a narrowing at its upper end 106. In other words again, the reservoir 10 has, at its upper end 106, a portion 108 whose width, measured perpendicularly to the main axial direction of the reservoir 10, is reduced relative to the remainder of the reservoir 10, said portion 108 being located at the upper end 106.

The reservoir 10 has here, at its neck 108, a cross section, the cross section being perpendicular to the main axial direction of the reservoir 10, of circular or substantially circular shape. The tank 10 has here, over the rest of its length, a cross section, of substantially square or rectangular shape.

The reservoir 10 comprises a dispensing orifice 107. Here, the dispensing orifice 107 is arranged at the upper end 106 of the reservoir 10. In other words, the dispensing orifice 107 is located at a free end of the neck 108 of the tank 10.

The reservoir 10 is here transparent. It is for example from glass or plastic. The distribution element 18 is here a pump. It is designed to allow the distribution of the liquid from the inside of the tank 10 to the outside of the tank 10. The pump 18 is here arranged at the dispensing orifice 107 of the tank 10. In particular, the dispensing 18 is designed so that its actuation by a user allows a distribution of the liquid contained in the reservoir 10. In other words, the dispensing element 18 is designed to allow the distribution of the cosmetic liquid from the inside of the reservoir 10 towards the outside of the bottle 1.

The pump 18 here comprises a base 189, a push button 180 and a dip tube 185. The dip tube 185 is designed to be immersed in the cosmetic liquid contained in the tank 10. It allows the suction of the cosmetic liquid to spray it to the outside through a spray orifice 182.

A translational movement of the push button 180, in a so-called actuation direction, relative to the base 189 allows actuation of the pump 18 by the user.

Here, the push button 180 has substantially a solid cylinder shape. The push button 180 includes a lower end 186 and an upper end 109 and extends in a main axial direction from one end to the other. The main axial direction of the push button 180 is here confused with its direction of actuation. The push button 180 here comprises a lateral surface 183 which extends parallel to the main axial direction of the upper end 109 of the push button 180 at its lower end 186. The push button 180 is provided at its upper end 109 with a bearing surface 184 designed to allow triggering or actuation of the dispensing element 18 and the distribution of the cosmetic liquid. The bearing surface 184 here extends orthogonally to the main axial direction of the push button 180.

The main axial direction of the push button 180 is here confused with the main direction of longitudinal extension of the bottle 1. The upper end 109 of the push button 180 is here merged with an upper end of the pump 18 and with the upper end 109 of the bottle 1.

The connecting ring 12 is designed to cooperate with the protective part 2. The connecting ring 12 is here a substantially cylindrical piece. Specifically, the connecting ring 12 has substantially a shape of hollow cylinder or crown. It is arranged on the neck 108 of the reservoir 10 in the vicinity of the upper end 106.

The connecting ring 12 here comprises a lower end 124 and an upper end 126 and extends in a main axial direction between the lower end 124 and the upper end 126. The main axial direction of the ring 12 is here confused with the main direction of longitudinal extension of the bottle 1.

The connecting ring 12 comprises an inner surface intended to cooperate with the neck 108 of the reservoir 10 and an outer surface intended to cooperate with the protective part 2. Each of the outer and inner surfaces extends axially from one end to the other. other of the connecting ring 12.

The connecting ring 12 further comprises a protuberance 122. The protuberance 122 here protrudes from the outer surface of the connecting ring 12. The protrusion 122 is for example a substantially cylindrical lug.

The connecting ring 12 is here screwed to the tank 10. For this purpose, the neck 108 of the tank 10 is here threaded at the outer surface 101 of the tank 10. Moreover, a tapping of the inner surface of the connecting ring 12 makes it possible to screw the connecting ring 12 to the tank 10. The connecting ring 12 is thus integral with the tank 10. In a variant, the tank 10 and the connecting ring 12 can be secured to each other for example by snapping, gluing, forced fitting, this without departing from the scope of the invention.

The position-setting piece 16 is a substantially cylindrical piece. It comprises a lower end 164 and an upper end 166 and extends in a main axial direction between the lower end 164 and the upper end 166. The main axial direction of the positioning part 16 is merged here with the main direction of longitudinal extension of the bottle 1.

The positioning member 16 is here arranged so that its lower end 164 is located at the upper end 126 of the connecting ring 12. In other words, the positioning member 16 is adapted to be arranged at the above the connecting ring 12, between the upper end 109 of the bottle 1 and the upper end 126 of the connecting ring 12. In particular, the arrangement of the positioning part 16 relative to the connecting ring 12 is made so as to allow an annular magnet 14 to be retained between the positioning part 16 and the connecting ring 12.

The pump 18 is arranged in the bottle so as to be partially surrounded by the positioning member 16. When the pump 18 is actuated, the push button 180 is seated inside the positioning part 16 so that the position-setting piece 16 then hides a part of the lateral surface of the push-button 180. The position-setting piece 16 serves in particular for an axial guiding of the pump 18.

As illustrated in particular in Figure 2, the protective part 2 extends longitudinally in a main direction of longitudinal extension X2 between an upper end and a lower end.

The protective part 2 here comprises a so-called protective envelope 20, designed to allow protection of the vial 1. The protective envelope 20 here defines an interior space of the protective part 2. The protective envelope 20 is advantageously rigid which contributes for example to the protection function. It comes from a transparent material. It can be made especially of glass or plastic.

In particular, the protective envelope 20 is here designed so as to make visible to the user the reservoir 10 of the bottle 1 through the protective envelope 20. The protective envelope 20 here has a substantially parallelepipedal and elongated shape, on at least part of its length. It has a lower end 204 and an upper end 206. The protective envelope 20 extends here in a main axial direction from the lower end 204 to the upper end 206. The main axial direction of the protective envelope 20 is here confused with the main direction of longitudinal extension of the protective part 2.

Here, the lower end of the protective casing 20 corresponds to a lower end 204 of the protection part 2 as well as to a lower end of the dispensing device when the protective part 2 and the bottle 1 are mounted. one to another.

As illustrated in particular in FIG. 4, it will be noted that when the bottle 1 and the protective part 2 are assembled together, their main directions of longitudinal extension X 1 and X 2 merge with a direction, said direction assembly, the bottle 1 with the protective part 2. The protective casing 20 is designed so that, once assembled to the bottle 1, the lower end 104 of the bottle 1 is arranged between the lower end 204 and the upper end 206 of the protective envelope 20 along the direction of extension of the assembly direction.

In other words, the dispensing device is designed so that, once the vial 1 and the protective part 2 are assembled to each other, the lower end 104 of the reservoir 10 does not protrude from the protective envelope 20 In other words, the vial 1 does not protrude from the protection part 2 at the lower end 204 of the protective casing 20. The lower end 204 of the protective casing 20 is designed to so as to allow the dispensing device to rest on a flat surface, in particular a table, the rim of a sink or a shelf, the lower end 204 being in contact with said flat surface. In this way, the protective part 2 has a function of both protection of the bottle 1 and support of the dispensing device.

Alternatively, the dispensing device may be designed so that, once the vial 1 and the protective member 2 are assembled together, the lower end 104 of the reservoir 10 protrudes from the protective casing 20 The reservoir 10 can then have a flattened shape at its lower end 104, the lower end 104 serving as a support for the dispensing device. The protective casing 20 is open at its lower end 204 so as to allow a passage of the bottle 1 from the outside of the protective part 2 towards the inside of the protective part 2. In other words, protective envelope 20 comprises, at its lower end 204, an opening 205 or an orifice, here an opening, adapted to allow a passage of the bottle 1 through it.

Here an outline of the opening 205 is substantially in a plane orthogonal to the assembly direction. The upper end of the protective casing 206 corresponds to a connection zone of the protective part 2.

In particular, the protective envelope 20 is here provided with a neck 208 or neck at its upper end 206. In other words, the protective envelope 20 ends with a narrowing at its upper end 206. In in other words, the protective envelope 20 has at its upper end 206 a portion 208 whose width, measured perpendicularly to the main extension direction of the protective envelope 20, is reduced compared to the rest of the protective envelope 20, said portion 208 being arranged at the upper end 206 of the protective envelope 20. The protective envelope 20 has here, at its neck 208, a cross section, the section transverse being perpendicular to the main axial direction of the protective envelope 20, of substantially circular shape. The protective envelope 20 has here, over the rest of its length, outside the neck 208, a cross section, of substantially square or rectangular shape.

The dispensing device comprises at least one assembly device designed to allow an assembly of the bottle 1 and the protective part 2 to each other in the assembly direction.

In particular, here, the assembly device comprises a protuberance 122 and a guide element 22. The protrusion 122 and the guide element 22 are intended to cooperate with each other to allow the assembly of the bottle. 1 and the protection part 2 to each other.

The bottle 1 is here provided with the protuberance 122. The protective piece is provided with the guide element 22. In a variant, the bottle 1 may for example be provided with the guide element 22 and the protection 2, it, the protuberance 122.

Here, the guide element 22 is designed to be arranged at the upper end 206 of the protective envelope 20, that is to say at the connection zone of the protective part 2. In particular, the Guiding element 22 is arranged here at least partially within the neck 208 of the protective casing 20. The guide element 22 is for example a hollow cylinder-shaped piece or crown. It extends in a main axial direction, coinciding with the main direction of longitudinal extension of the protective part, between a lower end and an upper end. The guide element 22 is for example made of plastic material. The guide element 22 is advantageously attached inside the neck 208 to which it is for example glued. The guide member 22 here comprises a shoulder or annular plate 225 and a side wall 227.

The side wall 227 has a lower end 224 and an upper end 226 respectively coincident with the lower end and the upper end of the guide member.

The side wall 227 extends in a main axial direction from the lower end 224 to the upper end 226, the main axial direction of the side wall 227 coinciding with that of the guide element 22.

The side wall 227 of the guide member 22 here comprises an outer surface facing the outside of the guide member 22 and an inner surface facing the inside of the guide member 22. In other words, the inner surface defines an inner space of the guide member 22. Each of the surfaces extends from one end to the other of the guide member 22 parallel to each other. The shoulder 225 is designed to encircle the side wall 227 and is integral therewith. In particular, the shoulder 225 projects radially from the outer surface of the side wall 227. The shoulder 225 here comprises a lower surface and an upper surface both extending orthogonal to the main axial direction of the guide element. 22. The shoulder 225 is designed to allow the arrangement of the guide member 22 at the upper end 206 of the protective casing 20. In particular here, the annular plate 225 is designed so that the bottom surface the shoulder is in contact with and bears on the free end of the neck 108 of the protective envelope 20.

As illustrated in particular in FIGS. 3a to 3c, the guiding element 22 is designed to cooperate mechanically with the connecting ring 12. In particular, the guiding element 22 is designed to cooperate mechanically with the protrusion 122 of the connecting ring 12. In other words, the protuberance 122 of the connecting ring 12 of the bottle 1 is designed to cooperate mechanically with the guide 222 the guide member 22 of the protective part 2. For this purpose, the side wall 227 of the guide element 22 is provided with a guide 222.

The guide 222 is here a longitudinal lumen crossing on both sides the side wall 227 of the guide member 22. In a variant, the guide 222 may be for example a recess or a groove formed on the inner surface of the wall lateral 227.

The guide 222 includes an abutment end 229 and an inlet end 220 and extends longitudinally along a guide path, not necessarily rectilinear, from the inlet end 220 to the abutment end 229. The inlet end 220 of the guide 222 is here located at the lower end 224 of the guide element 222. The inlet end 220 of the guide 222 is designed to allow the protrusion 122 of the bottle 1 of the engaging with the guide 222 of the protection member 2. The stop end 229 of the guide 222 corresponds to the end of the guide path of the guide 222 so that the protuberance can cooperate with the guide 222 while moving from the inlet end 220 to the stop end 229.

In other words, the protrusion 122 and the guide 222 are respectively designed as a cam and a cam path.

The guide 222 has a dimension called width measured perpendicularly to its direction of longitudinal extension. The width of the guide 222 is on most of its length at least equal, with a clearance, to a larger transverse dimension of the protuberance 122.

In particular, the guide 222 comprises at its inlet end 220 a portion 221, called flared portion. In particular, the flared portion 221 of the guide 222 at which the width of the guide 222 increases as one approaches the inlet end 220.

The flared portion 221 facilitates the entry of the protrusion 122 inside the guide 222. In other words, the flared portion 221 facilitates the engagement of the protuberance 122 inside the guide 222 and thus facilitate the interlocking and / or the assembly of the bottle 1 and the protective part 2 one in the other.

The guide 222 here comprises a first portion 228, said entry path, and a second portion 223, said locking path. The entry path 228 and the locking path 223 follow each other along the guide between the entry end 220 and the stop end 229. In other words, the guide 222 is designed to so that the protuberance 122 can move mechanically cooperating with, successively, the input path 228 and the guide path 223.

The inlet path 228 extends obliquely with respect to the main axial direction of the side wall 227 of the guide element 222. The locking path 223 extends substantially orthogonal to the direction axial axis of the side wall 227.

When the protrusion 122 cooperates with the locking path 223, the orientation of the locking path 223 relative to the direction of extension of the side wall 227, and thus relative to the assembly direction, makes it possible to block any translation of the protrusion 122 relative to the guide element 22 in the direction of extension of the protective part 2.

In other words, the locking path 223 of the guide 222 is designed so that, when the protuberance 122 is inside the locking path 223, then the vial 1 and the protective part 2 are blocked one by one. relative to the other in translation in the direction of assembly. In other words, when the protrusion 122 is located inside the locking path 223, the protective part 2 and the bottle 1 are locked relative to one another in translation in a direction of interlocking of the bottle. 1 inside the protection part 2.

The locking path 223 of the guide 222 is provided with a narrowing zone 2220 at which the width of the guide 22 is slightly reduced relative to the rest of the guide 22. The narrowing zone 2220 is arranged at a distance from the end stop of the guide. In particular, the narrowing zone 2220 is arranged along the guide 222 between the abutment end 229 and the inlet path 228.

The narrowing zone 2220 is designed to provide a mechanical resistance to the passage of the protuberance 122. The width of the guide 220 at the narrowing zone 2220 is, for example, slightly less than the largest transverse dimension of the protuberance 122.

Advantageously, the passage of the protuberance 122 at the narrowing zone 2220 of the guide 222 is by elastic deformation. This elastic deformation allows the user to feel when the protrusion 122 passes in the guide 222 at the narrowing zone 2220.

In addition to this warning function, the narrowing zone 2220 furthermore mechanically prevents the protuberance 122 from accidentally or involuntarily leaving the stop end 229. In other words, the narrowing zone 2220 makes it possible to secure the blocking of the bottle 1 and the protective part 2 with each other.

Apart from the flared portion 221 and the narrowing zone 2220, the width of the guide 222 is substantially equal, within one set, to the largest transverse dimension of the protuberance 122.

Figures 3a to 3c illustrate different steps of the assembly of the bottle 1 and the protective part 2 to each other. In FIG. 3a, the protuberance 122 is located at the inlet of the guide 222 at the flared portion 221. In FIG. 3b, the protuberance is situated in the vicinity of a junction between the locking portion 223 and a path 228. Precisely, the protrusion 122 is situated between the narrowing zone 2220 and the junction between the locking path 223 and the entry path 228. In FIG. 3c, the protuberance 122 is situated in a position, called stop, between the abutment end 229 and the narrowing zone 2220. As mentioned above, when the protuberance 122 is thus located, the vial 1 and the protective part 2 are locked in translation relative to each other according to the assembly direction.

As illustrated in FIG. 2, the protective part 2 comprises, for example, a magnet 24. The magnet 24 is designed to draw the bottle 1 towards the protection part 2 so that the protrusion 122 reaches the locking path 223 of the Guiding element 22. In other words, the magnet 24 participates in placing the bottle 1 in position relative to the protection part 2 when they are assembled to one another. The magnet 24 is designed to be arranged in the vicinity of the upper end 206 of the protective envelope 20. In particular, the magnet 24 is for example arranged at the upper end of the guide element 22 .

The dispensing device is designed so that the bottle 1 can be inserted inside the protection part 2 through the opening 205 of the protective casing 20. Precisely, when the user wishes to assemble the piece of 2 to the bottle 1, the user brings the connecting ring 12 of the bottle 1 into contact with the lower end 224 of the guide member 22 of the protective part 2. More precisely, the user brings the protuberance 122 of the connecting ring 12 at the lower end 224 of the guide member 22. The assembly is then made by bringing in particular the protrusion 122 at the inlet end 220 of the guide 222 of the guide member 22. The flared portion 221 of the guide 222 at the inlet end 220 is designed to allow the user to easily position the vial 1 and the shield 2 relative to each other. other e n view of their assembly.

In particular, the presence of the flared portion 221 makes it easy to cause the protrusion 122 to cooperate with the guide 222 by rotating the bottle 1 relative to the protective part 2. From there, the protuberance 122 is able to move to the stop position 229 through the entry path 228 and the locking path 223. The assembly of the bottle 1 and the protective part 2 is made in particular by rotation of relative to each other about an axis of rotation coincides with the assembly direction. The assembly device is then designed to transform the rotation into a translation movement along the assembly direction so as to cause the assembly of the bottle 1 and the protective part 2 with each other.

Advantageously, as illustrated in FIG. 1, the bottle 1 is also provided with a magnet 14. The magnet 14 of the bottle 1 is here designed and arranged in such a way that the bottle 1 is attracted by the magnet 28 of the protection part 2 during assembly. The magnet 14 may be replaced by an element, particularly metallic, ferromagnetic or magnetic, so as to be attracted by the magnet 24 arranged in the vicinity of the upper end 206 of the protective envelope 20, this without leaving the frame of the invention.

Similarly, the magnet 24 provided in the vicinity of the upper end 206 of the protective envelope 20 may be replaced by an element, in particular metallic, ferromagnetic or magnetic, so as to be attracted by the magnet 14 of the bottle 1 , this without departing from the scope of the invention.
