DETAILED DESCRIPTION

(6) In the description, the terms relating to positioning in space are understood with reference to the position of the bottle shown in the drawings.

(7) With reference to the drawings, the following are described below: a system for actuating a member 1 for dispensing a fluid product, a dispensing member 1 equipped with such an actuating system and a bottle intended to contain a fluid product and on which such a member 1 is mounted with a view to dispensing said fluid product. In particular examples, the product may be a liquid, a gel or a cream, for a cosmetic use or for pharmaceutical treatments.

(8) The bottle may be made of rigid material, in particular of glass or plastics material, in order to comprise a body 2 which defines a container 3 for packaging the product. The body 2 has a neck 4 mounted thereon which is formed in one piece with said body. The dispensing bottle also comprises a dispensing member 1 that is mounted on the neck 4, providing the means 5 for supplying said member inside the container 3, in order to allow said member to be supplied with packaged product.

(9) In the embodiments shown, the dispensing member 1 comprises a pump which has a body of which the periphery is mounted in the neck 4 without clamping. The body has a lower part which is provided with a supply opening, the supply means 5 comprising a dip tube having an upper part that is fixed in the opening and a lower part that extends in the container 3.

(10) The dispensing member further comprises a system for allowing it to be attached to the neck 4 of the bottle, said system having a socket 6 that is intended to be attached to said neck in a sealed manner. In the embodiments shown, the attachment socket 6 comprises a frame 7 which has an outer envelope of revolution, the dispensing member 1 being rigidly connected to said frame within said envelope.

(11) With reference to the drawings, the frame 7 comprises an annular bearing surface 8 on which the outer envelope is formed, and a radial wall 9 which is mounted on top of said annular bearing surface. Furthermore, the frame 7 comprises an upper wall 10 which is provided with an opening in which the dispensing member 1 is mounted, said upper wall being connected to the radial wall 9 by means of a wall 11. Moreover, in order to ensure that the frame 7 is rigidly connected to the dispensing member 1, the wall 11 comprises a recess 12 for latching with a groove 13 that is formed on the body of said dispensing member.

(12) In the embodiments shown, the dispensing member 1 is attached to the neck 4 by interposing an annular seal 14 between the upper wall of the neck 4 and the radial wall 9 of the frame 7, said upper wall further comprising a sealing band 15. In a variant, the body of the dispensing member 1 may be clamped in sealed manner in the neck 4 such that it is possible to omit the seal.

(13) The frame 7 also comprises a skirt 16 which has a mounting configuration (FIGS. 1 and 2) in which said skirt can be positioned around an outer side wall of the neck 4 and a clamping configuration (FIG. 3-6) of said skirt around said side wall to ensure attachment.

(14) In the embodiments shown, the skirt 16 has tabs 16a that are arranged to latch under the outer side wall of the neck 4 in the mounting configuration. In a variant, the skirt 16 may have tabs 16a which can be folded radially from the mounting configuration into the clamping configuration.

(15) Moreover, the socket 6 comprises a flange 17 that is mounted around the outer envelope of the frame 7 so as to slide between a raised position and a lowered position. Therefore, the tabs 16 of the skirt 16 may be kept in the clamping configuration as the flange 17 is being moved into the lowered position.

(16) The dispensing member 1 further comprises an actuating system for allowing the fluid product to be dispensed, said system comprising a push button 18 of which the body 19 has a well 20 for mounting on a tube 21 for supplying said member 1 and a path 22 for dispensing said product as far as a discharge passage 23 that is formed in said push button.

(17) The actuating system further comprises a bushing 24, in which the push button 18 is axially movable over an actuating course of the dispensing member 1. In the embodiments shown, the bushing 24 comprises a cylindrical coupling 25 which is axially immobilised on the socket 6 with the option of rotation.

(18) In order to do this, the cylindrical coupling 25 has a cylindrical envelope which defines an upper cavity in which the push button 18 is axially movable, and a lower cavity for receiving the socket 6. In particular, the envelope comprises at least one projection 26 which extends radially from the lower wall thereof and close to the bottom of the lower cavity, said projection latching under an annular bead 27 that is formed on the flange 17 in order to allow the cylindrical coupling 25 to be axially immobilised on said flange with the option of rotation.

(19) The bushing 24 further comprises an outer collar 28 which is connected around the cylindrical coupling 25 for conjoint rotation, it being possible to produce said collar in one piece, in particular from a rigid material such as metal, and for example from aluminium, or from plastics material.

(20) In particular, the inner wall of the collar 28 is provided with ridges 29 which become embedded in the outer wall of the envelope of the cylindrical coupling 25 in order to allow said collar to be connected to said cylindrical coupling for conjoint rotation. In order to do this, in an optimal manner, the material of the collar 28 may have a hardness that is greater than that of the cylindrical coupling 25.

(21) In order to prevent the dispensing member 1 from being involuntarily actuated by the push button 18 being accidentally pressed, the actuating system further comprises a device for reversibly locking said actuation by preventing the axial movement of said push button.

(22) The locking device comprises an insert 30 which is mounted in the cylindrical coupling 25 of the bushing 24 with the option of relative rotation. The insert 30 has connection means for conjoint rotation that are engaged with the socket 6 of the dispensing member 1, and at least one deformable stop that is intended to interfere with the body 19 of the push button 18 in order to prevent the dispensing member 1 from being actuated.

(23) In particular, the insert 30 is arranged in the upper cavity in the cylindrical coupling 25, such that the lower end of the body 19 of the push button 18 comes into axial interference with the deformable stop in order to prevent the dispensing member 1 from being actuated.

(24) The locking device further comprises a structure that is connected to the bushing 24 for conjoint rotation, and in particular is formed inside the cylindrical coupling 25, said structure being arranged, by rotating the bushing 24 relative to the insert 30, to deform the stop between an active state in which said stop is arranged on the actuating course of the dispensing member 1 to interfere with the body 19 of the push button 18, preventing said actuation, and an inactive state in which said stop is at a distance from said course to allow actuation.

(25) In order to do this, the structure has a circumferential ramp 31 on which the stop is arranged, said ramp extending angularly between a minimum radial dimension for arranging the stop in one state and a maximum radial dimension for arranging the stop in the other state.

(26) With reference to FIGS. 1, 3 and 4, a first embodiment is described below in which the cylindrical coupling 25 has an inner plate 32 which extends between the lower and upper cavities, and on which the circumferential ramp 31 is formed. In particular, the inner plate 32 comprises an aperture 33 in a side wall from which the circumferential ramp is formed, and the stop comprises a finger 34 which is engaged in said aperture.

(27) In the above-mentioned figures, the inner plate 32 and the stop each comprise two apertures 33 and two fingers 34 which are distributed symmetrically relative to a longitudinal plane, each finger 34 being engaged in one aperture 33 in each case and comprising a distal end 35 with which the lower end of the body 19 of the push button 18 comes into axial interference when said fingers are in the active state. Therefore, the blocking of the push button 18 in a raised position is axially balanced in order to prevent the dispensing member 1 from being actuated.

(28) With reference to FIGS. 3c and 4b, each aperture 33 has a first end 36 which extends, according to a minimum radial dimension r, relative to the centre of the upper cavity and a second end 37 which extends, according to a maximum radial dimension R, relative to said centre, the ramp 31 extending angularly between said ends, having a radial dimension that varies continuously between said minimum and maximum radial dimensions. Therefore, during rotation of the bushing 24, each ramp 31 slides on the side of a finger 34 in order to progressively deform said finger, and therefore said stop, between the active and inactive states thereof.

(29) Moreover, each end 36, 37 of an aperture 33 is arranged so that the finger 34 abuts said aperture at the end of the angular course of the bushing 24, in order to define the active state and the inactive state of the deformable stop, respectively.

(30) In particular, the fingers 34 form means for connecting the insert 30 to the dispensing member 1 for conjoint rotation. In order to do this, the insert 30 has a ring 38, on which the fingers 34 extend axially, said ring being mounted in the socket 6 so as to be interposed between the flange 17 and the wall 9 of the frame 7. Moreover, the flange 17 has two openings 39 that are distributed symmetrically relative to a longitudinal plane, a finger 34 being angularly immobilised in one of said openings respectively.

(31) With reference to FIGS. 2, 5 and 6, a second embodiment is described below in which the bushing 24 has a rim 40, on the inside of which the circumferential ramp 31 is formed. In particular, the envelope of the cylindrical coupling 25 comprises an upper portion on which the rim 40 is formed, the circumferential ramp 31 being formed on the inner wall of said rim so as to extend in the upper part of the upper cavity.

(32) Moreover, the insert 30 has a deformable ring 41 which is mounted in the rim 40 and has an upper wall 42, with which the lower end of the body 19 of the push button 18 comes into axial interference when the stop is in the active state.

(33) In particular, the fact that the upper wall 42 extends circumferentially and continuously around a longitudinal axis allows the blocking of the push button 18 in a raised position to be axially balanced, in order to prevent the dispensing member 1 from being actuated.

(34) In order to ensure that the ring 41 is connected to the dispensing member 1 for conjoint rotation, the socket 6 comprises at least one projection 43 on which said ring is angularly immobilised.

(35) More specifically, the frame 7 comprises four projections 43 that are formed on the wall 9 and are distributed symmetrically in pairs relative to a longitudinal plane, the flange 17 having two openings 44, in each of which a pair of projections 43 is arranged so as to extend axially. Moreover, the ring 41 comprises two lower cutouts 45 which are distributed symmetrically relative to a longitudinal plane, and in each of which a pair of projections 43 is intended to be arranged in order to angularly immobilise said ring.

(36) As shown in particular in FIGS. 5c and 6b, the ring 41 has two radial dimensions that are minimum and maximum respectively, said dimensions being arranged together with the dimensions of the ramp 31 so that said ring interferes with the body 19 of the push button 18 when the maximum dimensions of said ramp and said ring are arranged opposite each other (FIGS. 5b and 5c), and so that said ring does not interfere with said body when a maximum dimension and a minimum dimension of said ring and said ramp are arranged opposite each other (FIGS. 6a and 6b).

(37) In order to do this, the ring 41 and the rim 40 each have an elliptical geometry which, by a relative offset of 90, successively form a substantially cylindrical hole in the inactive state (FIG. 6b) and a substantially elliptical hole in the active state (FIG. 5c).

(38) More specifically, the ring 41 and the rim 40 each have two wall portions 46, 47 having a minimum radial thickness a, c and two wall portions 48, 49 having a maximum radial thickness A, C, the wall portions 46, 48, 47, 49 having the same radial thickness a, A, c, C being arranged opposite one another in pairs.

(39) Therefore, when the thickest wall portions 47, 49 of the rim 40 and of the ring 41, therefore the respective maximum radial thicknesses A, C, are arranged opposite one another in pairs, the ring 41 is deformed so as to form an elliptical hole, of which the small diameter forms a minimum radial dimension allowing the thickest wall portions 47 of the stop to interfere with the body 19 of the push button 18.

(40) Similarly, when the thickest wall portions 47, 49, therefore the maximum radial thicknesses A, C, of one of the rim 40 and the ring 41 are arranged opposite the thinnest wall portions 46, 48, therefore the minimum radial thicknesses a, c, of the other of said ring and said rim, the ring 41 is deformed so as to form a cylindrical hole, of which the diameter forms a maximum radial dimension allowing the wall portions 46, 47 of the stop to be at a distance from the actuating course of the push button 18.

(41) Advantageously, this second embodiment makes it possible to activate or deactivate the locking device independently of the direction of rotation of the bushing 24, and this facilitates said activation and hence the use of the bottle.

(42) Moreover, the rim 40 and the ring 41 have a relative-rotation interface which is provided with means for indexing the state of the ring 41.

(43) With reference to the drawings, the rim 40 comprises four axial recesses 50 which are formed on the circumferential ramp 31 so as to be spaced apart in pairs by an angle of 90. Similarly, the ring 41 comprises two axial projections 51 which are formed on an outer wall of said ring so as to be spaced apart in pairs by an angle of 180, said projections being intended to be engaged in two diametrically opposed recesses 50 in order to arrange said ring in one or the other of its states.

(44) Therefore, to move the ring 41 from one state to another, it is sufficient to turn the bushing 24 over an angular course of 90, first to remove the projections 51 from the recesses 50 defining the first state and then until said projections are engaged in the recesses 50 defining the second state.

(45) Moreover, the projections 51 and/or the recesses 50 may be arranged so that arranging said projections in two of said recesses is accompanied by a characteristic clipping sound in order to indicate to the user of the bottle that the locking device has been correctly activated or deactivated.
