DETAILED DESCRIPTION

(34) There has been represented in FIG. 1 a display unit 1 including a support 2 provided with a plurality of openings 3 each receiving a dispensing system 10 including a container 20 and a dispensing device 30 fixed to that container 20.

(35) Each container 20 contains a bulk product, preferably a dry product, in particular a food product, for example cereals, dried fruits, spices, sugar, flour, preserves, etc, . . . .

(36) The display unit 1 includes at least one space 4 enabling placing under the dispensing orifice 31 of a device 30 a collecting means 40 such as a jar, a box or a sachet, to collect the product delivered by gravity by the dispensing system 10. As illustrated, the collection means is preferably a jar having a threaded neck 41, as illustrated in FIGS. 2 and 3.

(37) The dispensing device 30 includes a body 32 which as shown may include a shouldered cylindrical part 32a connected at the top by a conical part 32b to a cylindrical part 32c of greater diameter serving as a nozzle for connecting the container 20.

(38) The cylindrical part 32c is threaded internally for fixing it to a threaded neck 21 of the container 20.

(39) The shouldered cylindrical part 32a is also threaded internally to enable the collecting jar 40 to be screwed onto the device 30, as illustrated in FIGS. 1 and 3.

(40) The body 32 may include an interior shoulder 34 at the base of the cylindrical part 32c serving as a seat for an annular seal 50 that is clamped between the end of the neck 21 and the shoulder 34.

(41) The shouldered cylindrical part 32a may include a wall 35 situated at the level of the shoulder in this part, which serves as a seat for an annular seal 51 intended to be placed between the wall 35 and the end of the neck 41 of the jar 40.

(42) The region of the body 32 situated between the wall 35 and the conical part 32b houses a first part 70 provided with a control handle 71, as shown in FIGS. 4 and 5, a second part 80 and a third part 90 equipped with an adjustment lever 91.

(43) The first part 70 and the second part 80 together form a shutter.

(44) The second part 80 is fixed relative to the body 32 and the first part 70 is able to turn about the longitudinal axis X of the system 10 when the user moves the handle 71. The latter is accessible from the outside through a first opening 81 in the second part 80 and a second opening 37, overlapping the first, in the body 32.

(45) The second part 80 includes a tubular skirt 82 and a bottom wall 83 through which pass four openings 84 disposed at 90° to one another.

(46) The first part 70 includes a tubular skirt 72 concentric with the skirt 82 and guided in its rotation movement by the latter and a bottom wall 73 through which pass openings 74.

(47) The third part 90 includes a tubular wall 92 interrupted angularly over an angular sector 94 the extent of which is for example between 90° and 150° inclusive.

(48) The body 32 includes an opening 38 through which the adjustment lever 91 exits and air inlet orifices 39 on the opposite side.

(49) In the FIG. 2 example the openings 37 and 38 are situated on the same side of the body 32 so that the handle 71 and the lever 91 are easily actuated by the person wishing to use the device.

(50) A return spring 100 acts between the first and second parts 70 and 80 to urge the first part into a blocking position in which the openings 74 in the bottom wall 73 overlap the solid parts of the bottom wall 83. This spring 100 is for example a coil spring attached at its ends to the parts 70 and 80, respectively, extending outside the skirt 72 around the latter. The skirt 82 may include a corresponding slot 88 receiving the spring 100 within its thickness, as can be seen in FIG. 6 in particular.

(51) The blocking position advantageously corresponds to the handle 71 coming to abut against one end of the opening 81 and/or of the opening 37, the openings 81 and 37 advantageously having the same angular extent and the same height.

(52) When the handle 71 is actuated the first part 70 is moved angularly relative to the second 80 and the openings 74 and 84 overlap, enabling the product to pass through.

(53) The spring 100 advantageously allow complete overlapping of the openings 74 and 84, and this position preferably corresponds to the handle 71 coming to abut against one end of the opening(s) 81 and/or 37.

(54) When the handle 71 is released, the spring 100 returns it into the blocking position.

(55) The third part 90 is situated axially under the second 80 and is able to turn relative to the latter if the user operates the adjustment lever 91.

(56) The third part includes a tubular skirt 92 and a bottom wall 94 through which pass openings 95 that are for example, as shown, four in number and disposed at 90° to one another. The skirt 92 includes an open sector 99.

(57) Depending on the angular position of the third part relative to the second, the openings 95 overlap the openings 84 to a greater or lesser extent and the passage section offered to the product is modified, which makes it possible to act on the flow rate of the flow.

(58) The angular extent of the open sector 99 is sufficiently large for the orifices 39 not to be masked by the skirt 92 regardless of the position of the lever 71 in the opening 38.

(59) The device 30 may equally include an annular deflector 110 that as shown in FIG. 6 comes to be positioned above the assembly formed by the nesting of the parts 70 and 80, has a top face 111 having the same inclination as the conical part 32b, and the bottom edge of which is situated vertically in line with the radially interior surface of the skirt 72.

(60) The device 30 includes a spout 120 that defines the dispensing orifice 31 at its bottom end.

(61) In the example considered, this spout 120 has circular symmetry about the longitudinal axis X of the device 30 with a flange at its top edge fixed to the wall 35.

(62) The cylindrical part 32a of the body 32 is threaded internally to enable the jar 40 to be screwed on, if necessary, as illustrated in FIG. 1.

(63) Numerous modifications may be made to the dispensing device without departing from the scope of the present invention.

(64) In particular, as illustrated in FIG. 7, there may be used containers 20 of conical general shape with a threaded neck 21 connected at the base of the cone by a wall 22 generally perpendicular to the longitudinal axis of the container.

(65) When it is coupled to the dispensing device 30 the container may rest with its wall 22 on the support 1 with the neck 21 oriented downward.

(66) When the container must be filled or changed, it may be positioned on the support 1 after turning it over, as illustrated in FIG. 7. The diameter of the opening 3 of the support 1 is smaller than that of the container, as measured at the base of the cone.

(67) The opening 3 may be flanked by an annular depression 4 such as a recess, as can be seen in FIG. 7, which enables the container to be centered in the opening 3 when it is in the position of use, the diameter of this recess 4 substantially corresponding to the greatest diameter of the container at the base of the cone.

(68) There has been represented in FIGS. 8 and 9 a variant support 1 including a first ring 130 at its base, resting on the floor, and three feet 131 connected at their bottom end to the ring 130 and joined at their top end by a second ring 132 of smaller size than the first but with an inside diameter less than the greatest diameter of the container 20 so as to retain the latter when it is turned over, as illustrated in FIG. 8.

(69) The ring 132 may as illustrated be flanked by a peripheral rib 133 for centering the container 20 when the latter is positioned on the support 1 with the neck 21 at the bottom, as in FIG. 9.

(70) A variant dispensing device 30 will now be described with reference to FIGS. 10 to 16.

(71) In this variant the spout 120 is a part adapted to be screwed onto the body 32 and to this end includes an externally threaded skirt 123 in the top part. The seal 51 may be positioned between the bottom of the housing receiving the skirt 123 and the end of the latter, as can be seen in FIG. 12.

(72) The air inlet orifices 39 are in this example positioned under the opening 38 allowing the flow rate adjustment lever 91 to exit.

(73) The skirt 92 of the third part may include a notch 98 facing these orifices so that the latter are not blocked by the skirt 92.

(74) The first part 70 includes separators 150 more particularly visible in FIG. 15.

(75) These separators 150 have inclined flanks 151 that open at the bottom onto the orifices 74 in such a manner as to guide the flow of product toward the latter.

(76) It is seen in FIG. 15 that the separators 150 may extend radially as far as a central region 78 of the bottom wall 73, which improves the mechanical retention of the latter. The separators 150 may have a height that decreases toward the center of the first part, as illustrated.

(77) The skirt 72 of the first part 70 may include a lug 79 in the top part that engages in a corresponding notch 89 formed in the top edge of the skirt 82 of the second part 80 so as to limit the angular movement of the first part relative to the second between the completely closed and fully open positions.

(78) The separators 150 may be a different shape, and there has been represented in FIG. 16 by way of example a variant shutter in which the separators take the form of straight partitions connected perpendicularly to the bottom wall 73 in the median plane separating the two adjacent openings 74.

(79) The handle 71 may take multiple forms, for example the form of a straight rod with no ball at its end, as illustrated in FIG. 17.

(80) The support 1 may be produced so as to enable placement of the dispensing devices 30 from above, the latter being retained for example by pressing a flange 160 provided at the end of the body 32 against the top face of the support wall 1 flanking the opening 3, as can be seen in FIG. 18.

(81) Each opening 3 may be provided with a cutout 6 allowing the passage of the handle 71 and, where appropriate, of the adjustment lever 91.

(82) Of course, the invention is not limited to the embodiments that have just been described.

(83) Numerous other modifications may be made to the containers, dispensing devices or supports without departing from the scope of the present invention.

(84) For example, the dispensing device 30 may be produced with no flow rate adjustment lever, the third part 90 being absent or mounted in a manner that is not adjustable from the outside in a position corresponding to the required flow rate. If necessary, the flow rate may be adjusted merely by moving the handle 71 of the shutter.

(85) The number of openings and the shape of the openings produced in the first and second parts may be different.

(86) Markers or detents may be provided to assist the user to assess the movement of the handle 71 of the shutter or of the lever 91 for adjustment of the flow rate.

(87) A variant of the dispensing device 30 has been represented in FIGS. 19 to 27.

(88) In the example illustrated the dispensing device 30 includes a body 32 having a top part 32c of cylindrical shape threaded internally for fixing it into the threaded neck 21 of the container 20, as illustrated in FIG. 19.

(89) The body 32 includes separators 150 projecting toward the container 20.

(90) The body 32 is connected at the bottom to a second part 80. Unlike in the embodiments described above, the second part 80 is disposed outside the body 32.

(91) This second part is fixed relative to the body 32. The latter is in particular fixed in a permanent manner, for example by welding, brazing, riveting, gluing or any other means.

(92) Alternatively, the second part is fixed to the body in a removable manner, for example screwed thereto.

(93) In the example illustrated, the second part 80 includes tubular skirt 82 and a bottom wall 83 through which pass three openings 84 disposed at 120° to one another.

(94) To facilitate the flow of the bulk product toward these openings 82 the separators 150 of the body 32 advantageously have inclined flanks 151, as illustrated in FIG. 20 in particular.

(95) The flow may equally be guided by means of a guide member 170 serving as a funnel. The latter is disposed at the center of the body 32, in particular at the bottom of the flanks 151.

(96) In the example illustrated, the guide member 170 includes a rod having an axis coinciding with the longitudinal axis X of the system 10. The rod 170 includes first and second rod portions 171 and 172 with different diameters separated by a shoulder 173.

(97) The first rod portion 171 includes a plurality of paddles 174 and 175 extending laterally from the rod, for example perpendicularly thereto.

(98) FIG. 25 illustrates an example in which the first rod portion 171 includes two pairs of paddles 174 and 175 extending at different heights from the shoulder 173. The paddles of each pair extend on either side of the rod, at the same height, in opposite directions along the same axis of extension Y1 or Y2. The axes of extension of the two pairs Y1 and Y2 are preferably perpendicular.

(99) The second rod portion 172 extends through a central opening 195 in the body 32.

(100) The opening 195 is preferably formed by a tubular abutment 190 of the body extending downward along the longitudinal axis X of the system 10 through an orifice 180 in the second part 80.

(101) The tubular skirt 82 includes a thread for fixing a spout 120, as illustrated in FIGS. 19 and 24.

(102) The second part 80 accommodates a first part 70 provided with a control handle 71 and a third part 90, as illustrated in FIGS. 26 and 27.

(103) The first part 70 and second part 80 together form a shutter.

(104) As described above, the first part 70 is mobile relative to the second part 80. The latter is able to turn about the longitudinal axis X of the system 10 when the user moves the handle 71. The latter is accessible from the outside through an opening 81 in the second part 80. In the example illustrated, the handle 71 is a straight rod.

(105) The second part 80 includes a passage 85 for the handle 71 thereby facilitating mounting and demounting the first part 70.

(106) The first part 70 includes a tubular skirt 72 concentric with the skirt 82 and guided in its movement in rotation by the latter and a bottom wall 73 through which openings 74 pass, here three in number.

(107) Like the embodiments referred to above, a return spring, not shown, is disposed between the first and second parts 70 and 80. The latter acts between the first and second parts 70 and 80 to urge the first part into a blocking position in which the openings 74 in the bottom wall 73 overlie the solid parts of the bottom wall 83.

(108) The blocking position advantageously corresponds to the handle 71 coming to abut against one end of the opening 81.

(109) When the handle 71 is actuated, the first part 70 is moved angularly relative to the second 80 and the openings 74 and 84 overlap, as illustrated in FIGS. 21a and 21b, which allows the product to pass through.

(110) When the handle 71 is released the spring returns it to the blocking position as illustrated in FIG. 22.

(111) The third part 90 is situated axially under the second part 80, between the latter and the first part. This third part includes a bottom wall 94 with openings 95 through it that are for example, as illustrated in FIG. 27, three in number and disposed at 120° from one another.

(112) In the example illustrated the third part 90 is mounted in a manner that is not adjustable from the outside in a position corresponding to the required flow rate. Accordingly, depending on the angular position of the third part relative to the second, the openings 95 overlap to a greater or lesser degree the openings 84 and the passage section offered to the product is modified, as illustrated in FIGS. 28a to 28c, which makes it possible to act on the flow rate of the flow.

(113) The third part 90 has a central orifice 200, visible in FIG. 27, for the passage of the abutment 190. This allows in particular the fixing of the third part 90 relative to the second. This also allows the bottom wall 92 to come into direct contact with the wall 82 of the second part. Of course, the invention is not limited to the embodiments that have just been described.

(114) For example, the fixing of the container 20 on the dispensing device 30 can be carried out other than by screwing, as described with reference to FIGS. 29 and 30.

(115) In the embodiment illustrated in these figures, the body 32 of the device has a cylindrical part 32c serving as a nozzle for the removable fixing of the container.

(116) The body 32 has an internal part 32d disposed inside the cylindrical part 32c. This part has a frustoconical shape that widens toward the container. The two parts are fixed by welding for example.

(117) The internal part 32d is connected at the bottom to a second part 80. The part 80 may be fixed to the internal part, in particular by welding it thereto.

(118) As described above, the second part 80 has a tubular skirt 82 and a bottom wall 83 through which pass three openings 84 arranged at 120° to one another.

(119) In the same way as in the embodiment illustrated in FIGS. 19 to 28c, the separators 150 of the body 32 have inclined flanks 151, as illustrated in FIG. 30 in particular.

(120) The flow is also guided by means of a guide member 170 serving as a funnel. This is arranged at the center of the body 32, in particular at the foot of the flanks 151, and is similar to the guide member described above.

(121) The tubular skirt 82 has a thread for fixing a spout 120, as can be seen in FIGS. 29 and 30.

(122) The second part 80 accommodates a first part 70, provided with a control handle 71, and a third part 90, as illustrated in FIGS. 26 and 27.

(123) The first part 70 and the second part 80 together form a shutter.

(124) In the example illustrated, the handle is accessible from the outside through a first notch 86 of the second part 80 and a second notch 36 of the body 32 superimposed on the first.

(125) The first part 70 includes a tubular skirt 72 concentric with the skirt 82 and guided in its rotation movement by the latter and a bottom wall 73 through which pass openings 74, here three in number.

(126) As in the embodiments mentioned above, a return spring, not illustrated, is disposed between the first and second parts 70 and 80. The latter spring acts between the first and second parts 70 and 80 to urge the first part into a blocking position in which the openings 74 in the bottom wall 73 overlie the solid parts of the bottom wall 83.

(127) The blocking position advantageously corresponds to the handle 71 coming to abut against one end of the notch 86 and/or of the notch 36, the notches 86 and 36 advantageously having the same angular extent and the same height.

(128) The operation of the first part is similar to that of the embodiments described above.

(129) The third part 90 is situated axially under the second part 80, between the latter and the first part. This third part includes a bottom wall 94 through which pass openings 95 that, as illustrated in FIG. 27, are advantageously three in number and disposed at 120° to one another.

(130) In the example illustrated the third part 90 is mounted in a manner that is not adjustable from the outside in a position corresponding to the required flow rate.

(131) The tubular skirt 82 includes a thread for fixing a spout 120, as described above with reference to FIGS. 29 and 30.

(132) The support 1 may be adapted to allow placement of the dispensing devices 30 from above, the latter devices being for example retained by a flange 160 provided at the end of the body 32 bearing against the top face of the support wall 1 flanking an opening 3 in the latter, as can be seen in FIG. 30.

(133) In this example, unlike the above embodiments, the container is fixed without screwing, the container being simply placed on the device after turning it over so that the neck of the latter comes to bear against the lateral wall 32d of the body 32.

(134) In the examples illustrated the guide member 170 is fixed relative to the body 32.

(135) Alternatively, this guide member 170 is mobile relative to the body 32, as will be described hereinafter with reference to FIGS. 31 to 38.

(136) In this example, as described above, the guide member consists of a rod 170 including first and second rod portions 171 and 172 with different diameters separated by a shoulder 173.

(137) The first rod portion 171 includes a plurality of paddles 174 and 175 extending laterally from the rod, for example perpendicularly thereto.

(138) The rod 170 is advantageously rigidly attached to the first part 70, in particular screwed thereto. The second rod portion 172 can therefore include a thread that is engaged in a threaded central orifice 77 of the bottom wall 71.

(139) Also, when the first part 70 is moved angularly relative to the second 80 by the handle the rod 170 and the paddles 174, 175 and 176 are driven in rotation which enables both guiding of the product toward the openings 84 of the second part and stiffing thereof.

(140) In the embodiments illustrated the second part 80 includes a skirt 82 of frustoconical shape.

(141) The second part 80 includes openings 84 and between the openings thereof separators 150 projecting toward the container 20.

(142) These separators 150 advantageously have inclined flanks 151 guiding the flow toward the openings 84 situated at their base.

(143) The second part 80 is fixed, in particular welded, to the body 32 of the device.

(144) The second part 80 includes a central orifice 180 for the second rod portion 171 to pass through.

(145) A return spring 100 is attached at its ends to the parts 70 and 80, respectively. To this end the first and second parts each include an attachment point 270 and 260 of the corresponding end of the spring 100, as can be seen FIGS. 34 and 35 in particular.

(146) In this embodiment the third part 90 is absent. If necessary, the flow rate can be adjusted merely by moving the handle 71 of the shutter. The system 1 advantageously includes a plurality of first parts with openings of different sizes that mount in the device as a function of the bulk product and the flow rate required.

(147) The device includes a spout 120 that nests in the body 32. The latter preferably includes an abutment 33 to prevent undesirable descent of the spout into the body. The spout 120 includes spigots 123, in particular flexible spigots, to improve the retention of the latter against the internal wall of the body 32.

(148) The system 10 also includes a clamping part 230 for retaining the dispensing device 30 on the support 1.

(149) As illustrated in FIG. 32, the clamping part advantageously includes a plate 232 that comes to abut against the lateral edge 5 of the support 1 and two forks 235 substantially perpendicular to the plate 232.

(150) In the example illustrated, the forks 235 engage in grooves 250 formed on the lateral wall of the body 32, which enables tilting of the system once installed on the support to be prevented.

(151) In order to improve the retention of the clamping part 230 against the support the forks 235 may each include a slot 236 for the passage of one or more fixing means 400 such as screws for example.

(152) The clamping part 230 may also serve for fixing a label 300 for displaying for example information relating to the type of bulk product, its source, its price or any other useful information, as can be seen in FIGS. 31 to 33 in particular.
